Striker [57] ABSTRACT The operation of a production line including a cigarette making machine and a filter cigarette machine is regulated by a shift register which transports signals serving to initiate the starting and stoppage of various assemblies in the production line in a predetermined sequence. The shift register also serves to transport further signals produced by detectors which track filter cigarettes and their components. Such further signals are transmitted to an ejecting device which segregates those cigarettes which exhibit one or more defects or which are likely to exhibit defects because they are produced during certain stages of operation of the production line. The detectors scan the splices in a web of cigarette paper, the seam on the wrapper of a cigarette rod, plain cigarettes, filter rods, filter plugs and filter cigarettes.

No. 535 filed Jan. 5, I970, now US. Pat. No. 3,672,373 granted June 27, I972.  
 BACKGROUND OF THE INVENTION The present invention relates to improvements in apparatus for the production of rod-shaped articles, particularly for the production of plain and/or filtertipped cigarettes, cigars, cigarillos or analogous rod-shaped articles wherein two or more components are connected to or otherwise assembled with each other, for example, by means of adhesive-coated uniting bands or the like. The invention also relates to a novel method of producing and assembling two or more components to form plain and/or composite rod-shaped articles. The invention further relates to improvements in a method and means for segregating defective rodshaped articles and/or their components from satisfactory articles and/or components.  
  It is already known to provide a filter cigarette machine or a cigarette packing machine with detectors which produce signals whenever they locate a defective cigarette and/or a defective component of a cigarette. Such signals are stored and thereupon used to effect ejection or segregation of defective articles or components when such articles reach a predetermined ejecting station. The means for delaying the transmission of signals to the ejecting device may include a chain of time-lag relays or a shift register through which the signals indicating defective articles and/or components are caused to travel stepwise in synchronism with travel of defective articles and/or components toward the ejecting station. A magnetic shift register is disclosed, for example, in British Pat. No. 1,071,985.  
 SUMMARY OF THE INVENTION An object of the invention is to provide a filter cigarette machine or another apparatus for the production of rod-shaped articles (particularly rod-shaped tobacco-containing products) with novel and improved means for storing and transporting signals which are indicative of defective articles and/or components and to construct the signal storing and transporting means in such a way that it can perform one or more additional important functions.  
  Another object of the invention is to provide an apparatus (such as a production line including one or more machines) which embodies the improved signal storing and transporting means.  
 A further object of the invention is to provide an apparatus wherein the production of components and the and further treatment of components of rod-shaped articles are automatically started and stopped in a predetermined sequence to reduce waste and to facilitate supervision.  
  Still another object of the invention is to provide a novel method of operating a production line which includes one, two or more discrete machines and of operating the assemblies &#39;of parts in such machine or machines in an optimum sequence.  
  A further object of the invention is to provide a novel method of programming the operation of various assemblies in a production line, of automatically starting, regulating and terminating the operation of such assemblies, and of automatically segregating defective articles or their components with minimal losses in time and material.  
  The method of the present invention is utilized for regulating the operation of apparatus which includes assemblies for the production and/or processing of cigarettes or analogous rod-shaped articles and wherein the articles and their components travel along a predetermined path. The apparatus may include a cigarette making machine and/or a filter cigarette machine. The method comprises the steps of tracking the articles and their components along the path, generating first signals in response to detection of defective articles and- /or components, producing a succession of shift pulses and utilizing such pulses for transport of first signals, at the speed of travel of articles, to at least one first station, generating second signals for starting and/or stoppage of asseblies, and utilizing the pulses for transport of second signals to at least one second station. The first signals can be utilized at the first station to effect segregation of respective (defective) articles and/or components from the path.  
  The first and second signals are preferably transported by a shift register which transports the signals at the operating speed of the apparatus and whose inputs and outputs are connected with controller circuits which respectively initiate stoppage and starting of various assemblies in a predetermined sequence.  
  The novel features which are considered as characteristic of the invention are set forth in particular in the appended claims. The improved apparatus itself, however, both as to its construction and its mode of operation, together with additional features and advantages thereof, will be best understood upon perusal of the following detailed description of certain specific embodiments with reference to the accompanying drawing.  
 BRIEF DESCRIPTION OF THE DRAWING FIG. 1a is a schematic front elevational view of a cigarette making machine which forms one part of the improved apparatus;  
  FIG. lb is a schematic front elevational view of a filter cigarette machine which forms another part of the improved apparatus; and  
  FIG. 2 (composed of FIGS. 20 and 2b is a diagram of the means for controlling the operation of the apparatus which includes the machines of FIGS. 1a and 1b.  
 DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. la and lb illustrate an apparatus, here shown as a production line, which includes a cigarette making machine (FIG. 1a of the type: known as GARANT and produced by Hauni-Werke Korber &amp; Co. K.G., of  
 I-Iamburg-Bergedorf, Western Germany, and a filter cigarette machine (FIG. lb of the type known as MAX and also produced by the Hauni-werke. The filter cigarette machine receives plain cigarettes Z from the cigarette making machine and is placed at right angles thereto. For the sake of clarity, the machine of FIG. lb is shown at right angles with reference to its position relative to the machine of FIG. 1a.  
  The cigarette making machine of FIG. 1a comprises a distributor 1 which discharges tobacco shreds into an elongated channel 2 and onto the upper stretch of an endless belt 3. The latter advances the resulting tobacco steam&#39;lengthwise toward and into the circumferential groove of a suction wheel 7 which is driven to rotate in a counterclockwise direction, as viewed in FIG. 1a. A trimming device 8 is adjacent to the groove of the suction wheel 7 and serves to remove the surplus so that the uppermost part of the suction wheel 7 transports a filler stream which advances along the lower stretch of a compacting belt 13. The latter subjects the filler stream to a compressing action and the thus compressed filler stream thereupon enters a wrapping unit 14 which applies therearound a continuous web 17 of cigarette paper in a manner well known in the art. The web 17 is drawn from a reel 16 and is led above the upper stretch ofa garniture belt in the wrapping unit 14.  
  A photosensitive detector 419 (shown in the lower left-hand portion of FIG. 1a) forms part of a testing or control unit 319 (FIG. 2a) and serves to generate signals in response to detection of splices between successive sections of the web 17. Such splices are preferably opaque to facilitate detection by the detector 419.  
  The wrapped cigarette rod Zs is transported lengthwise along a paster 4 which applies adhesive to at least one of the marginal portions of the web 17. The thus coated marginal portions pass along a sealer or heater 6 which applies heat and pressure to form a reliable seam and to thus convert the filler and the web 17 into the wrapped cigarette rod Zs. The paster 4 is movable by an electromagnet 404 (FIG. 2a) which activates the paster in response to starting of the cigarette making machine. The heater 6 is movable up and down toward and away from the path of the cigarette rod Zs by an electromagnet 406 (FIG. 2a) which lowers the heater and places it in operative position in response to starting of the cigarette making machine. The formation of the seam on the wrapper of the cigarette rod Zs is tracked by a photosensitive detector 407 which forms parts of a controller circuit 807 (FIG. 2a) for starting the cigarette making machine. The detector 407 generates signals as long as the heater 6 fails to produce a satisfactory seam.  
  A cigarette rod mutilating or breaking device 9 is located downstream of the detector 407 and is movable between an operative position 9A and an inoperative or idle position 98. When in the position 9A, the multilating device 9 directs the cigarette rod Zs into a collecting receptacle 18; this takes place when or as long as the seam on the wrapper of the rod Zs is unsatisfactory. When the multilating device 9 moves from the position 9A to the position 9B, it breaks or severs the rod Zs whereupon the leading end of the satisfactory rod (delivered by the garniture belt 15) advances past the multilating device 9 and into the aligned tubes 19 ofa cutoff 21. A tube cleaner, here shown as a blower nozzle 403a, is located at the cutoff 21 to expel cigarettes, to-  
 bacco shreds and dust from the tubes 19 on starting of the cigarette making machine. The cutoff 21 severs 21 the rod Zs at regular intervals to produce a single file of cigarettes Z of unit length. The nozzle 403a receives compressed fluid in response to opening of a solenoidoperater valve 403 (FIG. 2a)  
  The cigarette making machine further comprises a controller circuit 810 (FIG. 2a) which also regulates the starting of assemblies in the machine and includes a photosensitive detector 410 located past the cutoff 21. The detector 410 is designed to detect the absence of cigarettes Z in the path along which the cigarettes move away from the left-hand tube 19. For example, if the leading end of the cigarette rod Zs which was broken off by the mutilating device 9 fails to enter the tubes 19, the detector 410 generates signals to indicate the absence of cigarettes Z at the outlet of the cutoff 21.  
  The detector 410 is followed by an ejecting device 11 which preferably includes a nozzle 411a serving to discharge compressed air or other suitable gaseous fluid to thereby expel from the path a certain number of those cigarettes Z which are produced immediately after starting of the cigarette making machine. The admission of pressurized fluid into the nozzle 411a is controlled by a solenoid operated valve 411 (FIG. 2a).  
  A further photosensitive detector 413, which forms part of a controller circuit 813 (FIG. 20) tracks the entry of cigarettes Z into the flutes of a transfer drum 26. The controller circuit 813 regulates the operation of the cigarette making machine and the detector 413 tracks the entry of cigarettes Z into the flutes of the drum 26 when the machine is started and accelerated. The drum 26 transfers cigarettes Z to the filter cigarette machine of FIG. 1b. The detector 413 generates signals when the flow of cigarettes into the flutes of the transfer drum 26 is interrupted. Once the cigarette making machine operates at normal speed, the detector 413 takes over or performs the functions of the detector 407 and 410.  
  Referring to FIG. lb, the filter cigarette machine includes a magazine or hopper 35 for filter rods F of 6 times unit length. Such rods are discharged through a duct 33 into the flutes ofa cutting drum 36 which cooperates with two rotary disk-shaped knives 34 to subdivide each rod F into three filter plugs of double unit length. A photosensitive detector 421 tracks the filter rods F in the duct 33 and forms part of a controller circuit 821 (FIG. 2a) which serves to supervise the operating condition of the filter cigarette machine. The detector 421 generates signals in response to interruption of feed or filter rods F toward the cutting drum 36.  
  The filter plugs of double unit length are staggered on a staggering or shuffling conveyor 37 which comprises three wheels having different diameters and/or travelling at different speeds. The shuffling conveyor may be similar to that shown in FIGS. 25 in U.S. .Pat. No. 3,164,243 Rudszinat et a]. On leaving the conveyor 37, the filter plugs of double unit length are accepted by an aligning drum 38 which causes them to form a single file whereinthe plugs move sideways into the flutes (not shown) of a further drum 39. The drive for the drum 39 includes an electromagnetic clutch 414 which can be disengaged to thus interrupt the transport of filter plugs to the flutes (not shown) of a transfer drum 40. The drum 39 drives the drums 36, 37, 38 through a system of matinggears, not shown, so that these drums are arrested in response to disengagement of the clutch 414.  
  The transfer drum 26 at the discharge end of the cigarette making machine arrays the cigarettes Z in two rows and moves the cigarettes sideways into the flutes of an aligning drum 27 which in turn transfers pairs of cigarettes Z into successive flutes (not shown) of an assembly drum 28 in such a way that the cigarettes Z of each pair are spaced from each other by a distance which at least equals the length of a filter plug of double unit length.  
  The drum 49 is an accelerating drum which moves the plugs of double unit length at a speed exceeding the speed of such plugs on the drum 39 and serves to deliver filter plugs of double unit length into the gaps between pairs of cigarettes Z in successive flutes of the assembly drum 28. Thus, once a flute of the assembly drum 28 moves past the transfer station between the drums 28 and 40, it accommodates a group of coaxial rod-shaped articles including a centrally located filter plug of double unit length flanked by two cigarettes Z of unit length. The groups are delivered into the flutes of a further transfer drum 29 which provides each group with an adhesive-coated uniting band. Such bands are supplied bu a suction drum 46 which receives a continuous tape or web 410 from a bobbin 41. The tape 41a is. drawn by two advancing rolls 47 and is moved along a roller-shaped applicator 43 of a paster 42. The applicator 43 receives a film of paste from a roll 43a which dips into the adhesive-containing tank of the paster 42. The leading end of the tape 41a is severed by a revolving cutter 44 so that the tape yields a succession of uniting bands which are coated with adhesive at those sides which face away from the periphcry of the suction drum 46 and adhere to successive groups in the flutes of the transfer drum 29. The drive for the advancing rolls 47 of the feeding means for uniting bands includes an electomagnetic clutch 416 which can be disengaged to thus terminate the delivery of uniting bands to the transfer drum 29. The paster 42 becomes effective in response to energization of an elcctormagnet 417 whose armature 417a constitutes a lever ans supports a pair of rolls flanking a portion of the tape 4141. When the electromagnet 417 is energized. the armature 417a moves the adjacent portion of the tape 41:: downwardly and into contact with the film of adhesive on the applicator 43. A control unit 323 (FIG. 212) includes a detector 424 (FIG. lb) which is adjacent to the applicator 43 and produces a signal at the start and on termination of application of paste to the tape 41a. Such signal is transmitted by way of an electric switch 423. The energy source for the switch 423 has been omitted for the sake of clarity.  
  The groups of rod-shaped articles in the flutes of the transfer drum 29 (each such group is connected with an adhesive-coated uniting band delivered by the suction drum 46) advance past a further detector or initiator 426 which forms part of a control unit 326 (FIG. 2b) and serves to produce signals in response to detection of splices between successive lengths of the tape 410. Such splices are made readily detectable by application of pieces of metallic foil or the like in said splices. The drum 29 thereupon delivers groups and adhesive-coated uniting bands to a wrapping or rolling drum 48 which causes the groups to roll about their axes (preferably more than once) and to thus convert each uniting band into a tube which connects the respective filter plug of double unit length to the adjoining ends of aligned cigarettes Z. Thus, the drum 48 converts each group and the associated uniting band into a filter cigarette of double unit length. The shaft 48a of the drum 48 carries certain elements of a synchronization device 332. This device comprises a disk 332a on the shaft 48a and magnetic heads 332b, one for each flute (not shown) of the drum 48. The synchronization device 332 further comprises an induction coil 3320 which is adjacent to the path of magnetic heads 33211 and produces shift pulses at the rate at which the drum 48 receives and transports groups and uniting bands. The disk 332a rotates with and at the speed of the drum 48. The freshly wrapped filter cigarettes of double unit length move past and displace the trip 427a of an electric switch 427 which forms part of a control unit 327 (FIG. 2b). The trip 427a is positioned in such a way that it detects the presence or absence of filter plugs in successive filter cigarettes of double unit length. The switch 427 is caused to close when the trip 427a detects a defective cigarette of double unit length, i.e., a cigarette which does not include a filter plug of double unit length.  
  The presence or absence of uniting bands (i.e., tubes) in successive filter cigarettes of&#39; double unit length is detected by a photosensitive detector 428 which is located past the trip 427a and is also adjacent to the periphery of the wrapping drum 48. The detector 428 forms part ofa control unit 328 (FIG. 2b) and generates a signal in response to detection of a filter cigarette of double unit length which is without a convoluted uniting band.  
  The wrapping drum 48 delivers filter cigarettes of double unit length into successive flutes (not shown) of a testing drum 49 which is provided and associated with means for determining the presence ofleaks in the convolted uniting band and/or in the wrappers of cigarettes Z. Such means includes a nozzle 429a which blows a stream of testing air through successive filter cigarettes of double unit length. An evaluating device 429 evaluates the streams which have passed through the cigarettes and forms part of a testing or control unit 329 (FIG. 2b). The device 429 may include a diaphragm which causes the generation of an electric current having a strength which is indicative of the quality of tested cigarettes. A suitable testing unit which can be used in the machine of FIG. 1b is disclosed, for example, in US. Pat. No. 3,412,856.  
  The testing drum 49 transport filter cigarettes of double unit length past the solenoid valve controlled nozzle or nozzles 431 of an ejecting or segregating device 31. which receives signals from the unit 329 and expels from the drum 49 defective cigarettes before such cigarettes enter the flutes (not shown) of a cutting drum 50. The latter cooperates with a rotary disk-shaped cutter 50a which severs successive cigarettes of double unit length so that each such cigarette yields two filter cigarettes of unit length. The cutting drum 50 delivers pairs of filter cigarettes of unit length to an inverting drum 51 which inverts one cigarette or each pair end-for-end so that the filter plugs of all cigarettes face in the same direction. Such cigarettes are then delivered to a transfer drum 52 which transports them to a take-off drum 53. The latter can feed cigarettes to a belt or the like which transports them to a tray filling device or directly to a packing machine, not shown.  
  FIGS. 2a and 2b show schematically a shift register 300 which includes the synchronizing device 332 and has inputs 1 to Xll for signals indicating defects and/or serving to trigger the terminate various operation, and outputs D to T for such signals.

FlGS. 2a and 2b further show the aforementioned control units 319, 323, 326, 327, 328, 329 and a logical connection 912. These means detect defective products (cigarettes) or their components. The numeral 331 denotes the electrical means of the device 31 which serves for segregating or ejecting defective articles from their path. Still further, FIGS. 2:: and 2b illustrate the operative connections between the just enumerated means and the shift register 300. The latter includes one hundred and twenty shifting stages 51 to S120 for signals which serve to control the operation of the production line and for signals which indicate defects, and corresponding driving stages 333 (indicated by broken lines) for pulses furnished by the synchronization device 332. The register 300 is assembled in integrated building blocks of the series DT-MU-L produced by the Firm SGS of Milan, Italy. The number of stages in the register 300 corresponds to the number of discrete and unsevered cigarettes between the channel 2 of the cigarette making machine and the nozzle 431 in the filter cigarette machine. Each of the shifting stages S1 to S120 is a JK-Master-Slave flip-flop. The register 300 is of the type which is cleared prior to reeeption of a signal for starting or stoppage of the production line.

  The operation of the circuitry shown in FIGS. 2a and 2b (with continuous reference to the machines shown in FIGS. 1a and lb) is as follows:  
  It is assumed that the wrapping unit 14 of the cigarette making accommodates a length of the filler stream and a length of the web 17. The automatic starting of assemblies in the production line is then carried out in the following way. The master switch 418 is closed to start the low-speed operation of the cigarette making machine. The thus produced signal or pulse is transmitted to the trigger 518 which converts the signal into a definite control signal and transmits the signal to the input XII of the register 300 by way of the OR-gate 618. The control signal also causes the output d of the storage 320 to produce a signal A which remains there until the input a of the storage 320 receives an erasing signal. The control signal from the trigger 518 transmits an erasing signal to the input a of the storage 330 so that no signal B is present at the latters output (I. The storage 609 is caused to produce at its output 0 a signal which is transmitted to the amplifier 509. The latter emits a signal which energizes the electormagnet 409 so that the mutilating device 9 is moved to the position 9A.  
  Closing of the master switch 418 also causes the transmission of a signal in the direction indicated by arrow 1,000 to the starter of the drive for the cigarette making machine. Such drive preferably includes a pole reversible electric motor which drives the filter cigarette machine of FIG. 1b by way of the cigarette making machine of FIG. 1a. The just mentioned signal causes the drive to operate the belts and other movable conveying parts of the machine of FIG. 1a in the production line at a low speed.  
 The synchronization device 332 produces transporting pulses in synchronism with the operating speed of the production line and such pulses are transmitted parallel to all of the shifting stages S1 to S120. Such pulses push the control signal, which was admitted into the stage S11 at the input Xll, through the shift register 300 in stepwise fashion. This control signal triggers a series of operations during travel through the register 300, and such operations are started in a predetermined sequence. The output D emits a signal which is transmitted to one input of the AND-gate 70312; the other input of the AND-gate 703!) receives the signal A from the storage 320. The output of the AND-gate 7031) then produces a signal which is transmitted to the input b of the storage 603 whereby the output a of the storage 603 produces a signal which is transmitted to the amplifier 503. The signal which is produced at the output of the amplifier 503 actuates the valve 403 so that the latter admits pressurized fluid into the nozzle 403a of the cleaner for the tubes 19 of the cutoff 21.  
  In response to five successive stepwise advances, the control signal in the register 300 reaches the shifting stage 516. The output E then delivers a signal to one input of the AND-gate 703a. The other input of the AND-gate 703a receives the signal A and its output transmits a signal to the input a of the storage 603. Such signal erases the signal at the output (I of the storage 603 so that the valve 403 closes to terminate the cleaning of tubes 19.  
  In response to two further stepwise advances of the control signal through the register 300, the signal reaches the shifting stage S18. The output F then transmits a signal to one input of the AND-gate 704 the other input of which receives the signal A. The output of the AND-gate 704 transmits a signal to the input a of the storage 604 whereby the output of the storage 604 transmits a signal to the amplifier 504. The output of the amplifier 504 transmits a signal which energizes the electromagnet 404 for the paster 4. The latter then applies paste to one marginal portion of the web 17.  
  In response to seven further stepwise advances the control signal in the register 300 reaches the shifting stage S whereby the output G emits a signal to the corresponding inputs of the AND-gates 706 and 707. The other inputs of the AND-gates 706, 707 receive the signal A. The output of the AND-gate 706 transmits a signal to the input a of the storage 606 whereby the output 0 of this storage transmits a signal to the amplifier 506. The latter actuates the electromagnet 406 which moves the heater 6 to operative position. ie. the heater heats the seam which is formed by the overlapping marginal portions of the web 17 (with a film of paste furnished by the paster 4 therebetween). The output of the AND-gate 707 transmits a signal to the input I; of the storage 607 whereby the output a of this storage transmits a signal to the amplifier 507 which completes the circuit of the light source 407a in the photosensitive detector 407 at the time when the electromagnet 406 moves the heater 6 to operative position. The receiver 407b of the detector 407 then produces a signal as long as and until the seam between the marginal portions ofthe web 17 is defective. Such signal is transmitted to one input of the AND-gate 960.  
  When the control signal in the register 300 reaches the shifting stage S32, the output emits a signal to one input of the AND-gate 970; the other input of this gate receives the signal A. The output of the AND-gate 970 then emits a signal to one input of the AND-gate 960. If the seam of the web 17 is not closed during travel of the control signal from the stage S25 to the stage S32 (seven steps), the receiver 407] of the detector 407 continues to transit a signal to the other input of the AND-gate 960. The output of the gate 960 then emits a signal which is transmitted to the amplifier 508 by way of the OR-gate 530 and 608. The output signal from the amplifier 508 actuates the relay 408 which opens the circuit of the electric motor in the drive for the cigarette making machine so that .the latter is brought to a full stop.  
  The signal at the output of the OR-gate 530 is transmitted to one input of the OR-gate 608 and to the input a of the storage 607 (by way of the OR-gate 720). This erases the output signal of the storage 607 so that the circuit of the light source 4070 in the detector 407 is interrupted. Still further, the output signal from the OR-gate 530 is transmitted to the storage 330 by way of the OR-gate 340 so that the output d of the storage 330 produces a signal 8. This signal is transmitted to the inputs b and erases the output signals of the storages 606 and 604. When the storages 606 and 604 cease to transmit output signals, the heater 6 and the paster 4 become inoperative in response to deenergization of the electromagnets 406 and 404, respectively. Furthermore, the output signal from the OR-gate 530 is transmitted to the input a and erases the output signal of the storage 607. This deactivates the detector 407 by opening the circuit of the light source 407a.  
  1f the seam between the maginal portions of the web 17 closes properly in response to travel of the control signal from the shifting stage S25 to the stage S32, the receiver 40722 of the detector 407 does not produce a signal so that no output signal is produced by the AND- gate 960. The output of the NOT-gate 950 produces a signal which is transmitted to one input of the AND- gate 940. The other input of the AND-gate 940 receives the output signal from the AND-gate 970. Therefore, the output of the AND-gate 940 transmits a signal to the input VIII of the register 300. Such signal constitutes a fresh second control signal for starting of the production line as a function of closing of the seam during travel of the first control signal between the shifting stages S25 and S32. The first control signal is pushed through the register 300 behind the second control signal and cannot initiate any operations because the condition of the storages does not change in response to reception of additional signals.  
  The second control signal must perform five stepwise advances prior to reaching the shifting stage S37. The output K transmits a signal to one input of the AND- gate 709; the other input of this gate receives the signal A and its output transmits a signal to the input b of the storage 609 to thus erase the output signal from 609. This interrupts the circuit of the electromagnet 409 whereby the springbiased mutilating device 9 moves from the position 9A to the position 98 to thereby break or sever the cigarette rod 25.  
  After eight additional stepwise advances, the second control signal reaches the shifting stage S45 whereby the output L transmits a signal to the one input each of the AND-gates 710 and 711b. The other inputs of these AND-gates receives the signal A. The output of the AND-gate 710 transmits a signal to the input a of the storage 610 whereby the latters output 0 transmits a signal to the amplifier 510 which completes the circuit of the light source 410a in the detector 410. The latter is located downstream of the cutoff 21.  
  The receiver 410b of the detector 410 produces a signal in response to absence of cigarettes Z; this occurs, for example, when the leading end of the cigarette rod Zs fails to enter the tubes 19. The signal from the receiver 410b is transmitted to the amplifier 508 by way of the OR-gates 530 and 608. The amplifier 508 actuates the relay 408 which opens the circuit of the motor in the drive of the cigarette making machine to immediately bring the production line to a full stop.  
  The output signal from OR-gate 530 is further transmitted to the input b of the storage 610 (by way of the OR-gate 720) whereby the output signal from the storage 610 is erased and the detectors 407, 410 become inactive (opening of the circuits of light sources 407a and 410a). The output signal from the OR-gate 530 isfurther transmitted to the input b of the storage 330 (by way of the OR-gate 340) whereby the storage 330 produces the signal B which is transmitted to the inputs b of the storages 604, 606. This erases the output signals of the storages 604, 606 whereby the paster 4 and heater 6 are deactivated in the same way as described above (i.e.. in response to deenergization of the electromagnets 404, 406).  
  The output signal from the AND-gate 711!) is transmitted to the input 12 of the storage 611 so that the latters output d emits a signal which is transmitted to the amplifier 511. The latter transmits an amplified signal to the valve 411 for the nozzle 411a in the ejecting device 11.  
  If the flow of cigarettes Z is uninterrupted, no signal is transmitted by the detector 410. Then. in response to three further stepwise advances. the second control signal reaches the shifting stage S48 whereby the output M transmits signals to one input each of the AND-gates 712 and 711a. The other inputs of these AND-gates receive the signal A. The output of the AND-gate 711a transmits a signal to the input a of the storage whereby the latter erases its output signal. The valve 411 is then closed and the nozzle 411a of the device 11 ceases to eject cigarettes Z. Thus. the foremost three cigarettes Z are automatically ejected from the path in which they travel lengthwise toward the fluted drum 26.  
  The output of the AND-gate 712 transmits a signal to the input b of the storage 612 whereby the latters output d transmits a signal to the amplifier 512. This energizes the relay 412 which effects operation of the production line at a higher second speed.  
  When the second control signal reaches the shifting stage S51, the output N transmits a signal to one input of the AND-gate 713; the other input of the gate 713 receives the signal A and its output transmits a signal to the input b of the storage 613 so that the latters output d transmits a signal to the amplifier 513 which completes the circuit of the light source 413a in the detector 413. As mentioned above, the detector 413 forms part of the controller circuit 813.  
  The receiver 413b of the detector 413 produces a signal when no orderly transfer of cigarettes Z takes place into the flutes of the transfer drum 26. Such signal is transmitted to one input of the AND-gate 640. The other input of the gate 640 receives the signal A and the output of this gate transmits a signal to the amplifier 508 by way of the OR-gates 530 and 608. The output of the amplifier 508 transmits a signal to the relay 408 which immediately stops the two machines and the starting procedure is repeated, from the beginning. The output signal of the OR-gate 608 is also transmitted to the input a of the storage 612 whereby the latter deenergized the relay 412 which has caused the machine to operate at the higher speed. The output signal from the OR-gate 530 is further transmitted to the inputs b and a of the storages 610 and 607 by way of the ORgate 720. The storages 610 and 607 erase their output signals to thus deactivate the photosensitive detectors 410 and 407. Still further, the output signal from the OR- gate 530 is transmitted to the input b of the storage 330 by way of the OR-gate 340; the storage 330 then pro duces the signal B which is transmitted to the inputs h of the storages 604 and 606 whereby the latter storages erase their output signals to deenergize the electromagnets 404 and 406 and to thus deactivate the paster 4 and heater 6. The signal B is further transmitted to the input a of the storage 613 so that the latter erases its output signal and causes opening of the circuit of the light source 4130 in the detector 413.  
  When the second control signal reaches the shifting stage S (after nineteen additional steps). the output R emits a signal which is transmitted to the corresponding inputs of the AND-gates 716a and 714a. The other inputs of these AND-gates receive the signal A. The output of the AND-gate 714a transmits a signal to the input a of the storage 614 whereby the latters output c transmits a signal to the amplifier 514 which engages the magnetic clutch 414 in the filter cigarette machine. The output of the AND-gate 716a transmits a signal to the input a of the storage 616 whose output transmits a signal to the amplifier 516 which engages the clutch 416 for the advancing rolls 47. Thus, the bobbin 41 begins to pay out the tape 41a.  
  When the second control signal reaches the stage 876 (after six additional steps), the output S transmits a signal to one input of the AND-gate 717a the other input of which receives the signal A. The output of the AN D gate 717a then transmits a signal to the input a of the storage 617 whose output c transmits a signal to the amplifier 517 which energizes the electromagnet 417 so that the armature 417a lowers the tape 41a into contact with the applicator 43 of the paster 42. The signal from the output S is further transmitted to the OR- gate 720 and thence to the inputs b and a of the storages 610 and 607, respectively. This erases the output signals of the storages 610 and 607. Thus, the detectors 407 and 410 become inactive and the detector 413 takes over their functions. The signal from the output S is further transmitted to the input a of the storage 320 (by way of the OR-gate 720) whereby the storage 320 erases its output signal A (at d). This completes automatic starting of the production line.  
 The production line is stopped in the following way:  
  The first control signal is used for energization of the controller circuit 821 during starting of the production line. The output signal at J is transmitted to the input b of the storage 521 whose output d transmits a signal to one input of the AND-gate 621. This completes en ergization of controller circuit 821, i.e., the photosensitive detector 421 can participate in regulation of operation of the filter cigarette machine because one input of the AND-gate 621 receives a signal from the output 41 of the storage 521. Thus. the AND-gate 621 can transmit a signal as sson as its other input receives a sig&#39; nal from the detector 421. If the feed of filter rods F in the duct 33 is interrupted, the detector 421 transmits such signal to the other input of the AND-gate 621 whereby the latter&#39;s output transmits a signal to the trigger 721 whose output transmits a signal to the trigger 721 whose output transmits a control signal to the input 1X (shifting stage 531) of the register 300. At the same time. the output signal of the trigger 721 is transmitted to the input [2 of the storage 330 by way of the OR-gates 722 and 340 whereby the output (1 of the storage 330 produces the signal B. The signal B is transmitted to the input [2 of the storages 604 and 606 so that these storagcs erase their output signals to thereby deactivate the paster 4 and heater 6. The signal B is furthcr transmitted to the input a of the storage 613 which erases its output signal and deactivates the detector 413 ofthe controller circuit 813. Still further, the signal B is transmitted to the input a of the storage 521 which erases its output signal and deenergizes the controller circuit 821. The testing unit 319 is rendered inactive in response to transmission of the signal B to the input a of the storage 519.  
  The aforementioned third control signal which is transmitted to the input 1X in the shifting stage S31 travels stepwise and initiates operations which result in automatic stoppage of the production line. The operations which bring about the stoppage take place in a predetermined sequence to make sure that satisfactory cigarettes Z which are located in the flutes of drums in the filter cigarette machine are provided with filter plugs to form therewith filter cigarettes. During evacuation of cigarettes from the filter cigarette machine, the filler rod is caused to enter the collecting receptacle 18 (FIG. In) as soon as the electromagnet 404 deactivates the paster 4 and the electromagnet 406 deactivates the heater 6.  
  When the third control signal reaches the stage S52 (21 steps). the register output 0 transmits a signal to one input of the AND-gate 71412 the other input of which receives the signal B. The output of the AND- gate 714]: then transmits a signal to the input b of the storage 614 whereby the latter erases its output signal to deencrgize the clutch 414. When the third control signal reaches the stage S56, the output P transmits a signal to one input of the AND-gate 71711 the othet input of which receives the signal B. The output of the AND-gate 7171) then transmits a signal to the input b of the storage 617 which erases its output signal and thereby deenergizes the electromagnet 417 whose armature 417u moves the tape 41a away from the applicator 43.  
  When the third control signal reaches the stage S60, the output 0 transmits a signal to one input of the AND-gate 71611 the other input of which receives the signal B. The output of the AND-gate 716b then transmits a signal to the input b of the storage 616 which erases its output signal whereby the clutch 416 is deenergized and the rolls 47 stop the transport of the tape 41a.  
  When the third control signal reaches the shifting stage S70, the output R transmits a signal to one input of the AND-gate 708 the other input of which receives the signal B. The output of the AND-gate 708 transmits a signal to the amplifier 508 by way of the OR-gate 608 and the amplifier 508 deenergizes the relay 408 which immediately stops the motor of the drive for the cigarette making machine. At the same time, the input a of the storage 612 receives a signal which erases the output signal from storage 612 so that the relay 412 is deenergized. When energized, the relay 412 causes the motor for the cigarette making machine to operate at the higher speed.  
  The controller circuit 813 is energized by the second control signal during automatic starting of the production line. This controller circuit remains energized upon completion of starting of the production line. If there develops a flaw in operation of the machines. e.g., if the detector 413 detects the absence of cigarettes Z at the transfer drum 26, this detector produces a signal which is transmitted to corresponding inputs of the AND-gates 620 and 640. Since the signal A is erased on completion of starting of assemblies in the production line, the other input of the AND-gate 640 is without a signal and this gate fails to transmit a signal which, when present, would cause immediate stoppage of the motor for the cigarette making machine. The transmission of signal A is also terminated to the input of the NOT-gate 630, i.e., the gate 630 produces an output signal which is transmitted to one input of the AND-gate 620. The other input of the AND-gate 620 receives a signal from the detector 413 so that the gate 620 transmits a signal to the input b of the storage 330 by way of the OR-gate 340. The output (I of the storage 330 then produces the signal B which causes stoppage of various assemblies of the production line in the aforementioned sequence. The output signal from the AND-gate 620 is also transmitted to the trigger 622 by way of the OR-gate 522 whereby the trigger 622 transmits a control-signal to the input VII (stage $36) of the register 300. This fourth control signal travels through the register and causes automatic stoppage of various assemblies in the necessary sequence. This was de scribed above.  
  The production line can be stopped manually by way of the switch 422; When this switch is closed by hand, a signal is transmitted to the input of the trigger 622 by way of the OR-gate 522 whereby the trigger 622 transmits a signal to the input V11 of the register 300. The resulting control signal travels through the register and causes stoppage of various assemblies of the produc&#39; tion line in the aforedescribed predetermined sequence. The signal which is produced in response to actuation of the switch 422 is further transmitted to the input b of the storage 330 by way of the OR-gates 722 and 340 so that the output a of the storage 330 emits the signal B.  
  The various testing and ejecting devices which locate and segregate defective portions of the cigarette rod 25, defective cigarettes Z and other components are operated in the following way:  
  The first control signal is utilized to activate the testing unit 319 during starting of various assemblies of the production line. The testing unit 319 determines the presence of splices in the web 17. When the first control signal reaches the shifting stage S29, the output H transmits a signal to the input b of the storage 519. The output d of the storage 519 then transmits a signal to one input of the AND-gate 619. The detector 419 transmits a signal when it detects a splice in the web 17 and such signal is transmitted to the other input of the AND gate 619 whose output then transmits a signal to the trigger 719. The latter transmits a signal to the inputs X of the register 300. The testing unit 319 is activated only when the first control signal advances past the shifting stages S26, S27, S28, i.e., past those stages which receive the signal from the output of the trigger 719. This insures that the signals which indicate the presence of defective splices in the web 17 and enter the register ahead of the first control signal cannot start the assemblies of the production line. Thus, those splices which are detected while the first control signal travels from the input XII (stage S11) to the stage S29 (eighteen steps) cannot cause the generation of signals which would enter the register 300 because the storage 519 does not as yet transmit a signal to the corresponding input of the AND-gate 619.  
 The signal which appears at the output of the AND- gate 712 (and is transmitted by way of storage 612 and amplifier 512 to the relay 412 which effects operation of the motor at a higher second speed) is also transmitted to the inputs X1 by way of the logical connection 912 and controller circuit 812. The logical connection 912 is further connected with the input XII by way of the OR-gate 618. Thus, the inputs XI and XII receive signals which are indicative of defective articles. This is desirable because it was determined, by experience, the the fillers of cigarettes which are produced during shifting from lower speed to higher speed are unsatisfactory, i.e., that the weight of cigarettes which contain such fillers is without an optimum range.  
  The detector 424 of the control unit 323 transmits a signal to the trigger 523 during the initial stage of application of paste to the tape 41a. The signal transmitted by the trigger 523 is indicative of defective material and is admitted to the register 300 by way of the inputs VI. This is desirable because it was found that it re quires a certain interval of time before the paster 42 begins to apply adhesive at an optimum rate, i.e., that cigarettes containing the corresponding uniting bands should be segregated. The same applies for the last series of cigarettes which are produced directly prior to stoppage of the production line. The detector 424 produces a signal upon completion of operation of the paster 42 and such signal is transmitted to the trigger 524 which transmits a signal to the inputs V of the register 300.  
  The splices between the sections of the tape 41a consists of adhesive-coated aluminum foil. When such a splice passes along the initiator 426 of the control unit 326, the initiator produces a signal which is transmitted to the trigger 526. The latter then transmits a signal (indicative ofa defect) to the inputs IV of the register 300.  
  The trip 427a of the switch 427 in the control unit 327 contacts successive groups in the flutes of the wrapping drum 48 to detect the presence or absence of filter plugs of double unit length. The switch 427 transmits a signal to the trigger 527 whenever the trip 427a detects the absence of a filter plug, and the trigger 527 transmits a signal (indicative of a defect) to the input III) of the register 300.  
  The photosensitive detector 428 of the control unit 328 detects the presence or absence of convoluted uniting bands on the filter cigarettes of double unit length. If the detector 428 detects the absence of a uniting band, it produces a signal (indicative of a defeet) which is transmitted to the trigger 528. The latter transmits a signal to the input II of the register 300.  
  The signal evaluating device 429 of the testing device 329 is the last detecting or monitoring means along the path of cigarettes and of their components in the production line. This evaluating device is adjacent to the testing drum 49 and its function is to determine the presence or absence of leaks in the wrappers of filter cigarettes of double unit length. Such leaks can develop as a result of damage to wrappers during travel in the machines of FIGS. 1a and 1b, as a result of opening of a seam on a cigarette Z, as a result of imperfect convolution of a uniting band around the corresponding filter plug and the adjacent cigarettes Z, and/or for other reasons. The testing device 329 tests the streams of air which are conveyed through filter cigarettes of double unit length and compares the results of measurement with a standard value. For example, if a tested filter cigarette of double unit length has a leak, the rate of air&#39; flow is greater than normal. Some air will always pass through the wrapper of a filter because the web 17 is normally porous. The evaluating device 429 produces electric signals which are transmitted to the trigger 529. In the event that the signal transmitted to the trigger 529 is indicative of a defective article, the trigger transmits a signal to the input l of the register 300.  
  The ejection of defective articles is carried out in the following way:  
  When the register 300 receives a signal from the means 321, control unit 323, 326, 327 or 328, testing unit 329 or controller circuit 812, such signal travels toward the shifting stage S whereby the output T transmits a signal to the amplifier 531 which amplifies the signal and transmits it to the nozzle 431 of the means 331. The nozzle 431 then expels the defective article from the corresponding flute (not shown) of the testing drum 49. It will be seen that, irrespective of the nature of their defects, all defective completed articles can be segregated from satisfactory articles at a single station.  
  In heretofore known cigarette making machines, the tubes of the cutoff which severs a cigarette rod to form discrete cigarettes are cleaned manually by resorting to bellows, brushes or the like. In the apparatus of the present invention, the valve 403 which controlls the tube cleaning nozzle 403a receives a signal directly from the output D of the register 300 and insures automatic cleaning of tubes 19 at an appropriate time during starting of the apparatus. The control signal which reaches the output E of the register 300 automaticaly terminates the cleaning of tubes 19.  
  Also, in conventional cigarette making machines the heater and the paster for the web of cigarette paper are activated with a predetermined delay following starting of the machine. In such machine, the means for starting the paster and the heater normally comprises time-lag devices which delay the signal for a predetermined period of time to insure that the paster does not apply adhesive to the web and that the heater does not heat and press the seam until the conditions are such that the paster can engage a properly convoluted web which surrounds a satisfactory filler rod.&#39;ln the improved apparatus, the signals for activating the paster 4 and heater 6 are received from the outputs F and G of the register 300 so that they need not be stored in separate time-lag devices. Proper timing of activation of paster 4 and heater 6 is desirable to avoid ejection of too many satisfactory cigarettes and/or the formation of an unsatisfactory cigarette rod which must be discarded prior to reaching the cutoff2l. As a rule, defective sections of the rod Zs and defective cigarettes Z are opened up in special machines which serve to recover tobacco shreds for reuse in the cigarette making machine.  
  An advantage of the detector 407 is that it immediately detects a satisfactory seam so that the multilating device 9 can immediately break off the defective part of the rod and thus insures that the leading end of thesatisfactory rod can enter the tubes 19 of the cutoff 21. In many presently known cigarette making machines, the formation of the seam is observed by the person in charge; this requires much experience and care, especially in a modern machine wherein the rod travels at a high speed. The mutilating device 9 reacts to signals which are furnished by the register 300 (output K).  
  In accordance with presently prevailing practice, a cigarette making machine is designed to automatically eject a certain number of cigarettes which are produced immediately after starting of the machine. The device which effects such ejection receives a signal in response to starting of the machine and remains operative for a predetermined interval of time of average length. This is normally achieved by employing a suitable time-lag relay or the like. As a rule, the ejecting device is set to effect segregation of more cigarettes than necessary. In the apparatus of the present invention, the number of segregated cigarettes (namely, of those cigarettes which are produced immediately after starting) is reduced to a minimum because the ejection is started and termuated in response to signals which are shifted through the register 300. The means for ejecting those cigarettes which are produced immediately after starting of the cigarette making machine is capable of ejecting a certain minimum number of cigarettes irrespective of the operating speed of the machine. The register 300 transports signals which initiate ejection of presumably defective articles immediately after starting as well as such signals which terminate the ejection of potentially defective articles. It will be seen that the register 300 performs a large number of operations including transport of signals which are used to control the operation of various assemblies in the production line in a predetermined sequence during starting and stoppage as well as the transport of signals which are indicative of defective articles or defective components of articles and are used either to stop the production line (or one of its machines) or to effect segregation of defective articles or components.  
  The shift register also controls the changes in operation of the drive for the machine from low speed to higher speed. This reduces waste because the number of cigarettes which are produced durng the shortlasting low-speed operation is reduced to a minimum. At the present time, the person in charge determines the moment when the speed of the cigarette making machine is changed from lower to higher speed. This requires much experience and much carefulness on the part of the personnel.  
  As described above, the register also transmits signals which are used to stop the apparatus in response to detection of faulty operation. Stoppage in response to faulty operation is initiated by the detectors 413 (cigarettes Z) and detector 421 (filter rods F). In presently known apparatus, the signals which are produced in response to detection of flaws in operation of the machine or machines immediately stop the conveying parts. This produces considerable waste because many partly assembled components of the filter cigarettes remain in the apparatus. The register of the present invention causes stoppage of various assemblies in a predetermined sequence so that the waste is reduced to a minimum.  
  All such filter cigarettes which include one or more defective components are ejected at a single station (testing drum 49). Signals which are indicative of defective articles or components are transported to the output T.  
  Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that fairly constitute essential characteristics of the generic and specific aspects of the above described contribution to the art and, therefore, such adaptation should and are intended to be comprehended within the meaning and range of equivalence of the claims.
