with reference to fig1 an automatic glass blowing machine 11 is schematically presented , in which products 12 , for example , glass bottles or other containers , are blown out of a liquid glass mass . the products 12 leave the automatic glass blowing machine 11 on a conveyor belt , which is the delivery conveyor belt 13 of a weighing apparatus generally indicated with the reference symbol 14 . the weighing apparatus 14 , which will be more specifically described in the following in connection with fig2 is arranged at the point of transfer placed between the delivery conveyor belt 13 and a removal conveyor belt 15 and which is at an acute angle to it ; the removal conveyor belt 15 leads into a cooling oven 16 . the angle between the two conveyor belts 13 and 15 can be as desired and does not have to be an acute angle . it results from the spacial relationships ; that is , the respective arrangements of automatic glass blowing machine 11 and cooling oven 16 . it ought to be considered that usually the side of the apparatus which , as seen from the automatic glass blowing machine 11 , lies on the right of the removal conveyor belt 15 , must be , for operational reasons , very accessible , whereas the space between the automatic glass blowing machine 11 and the cooling oven 16 is unused . in fig2 the details of the weighing apparatus 14 can be better recognized . in this case , in the acute angle formed between the conveyor belts 13 and 15 , a weighing device 17 is arranged which has , as its core , a weighing cell 18 , which is an ordinary closed compartment that converts a weight placed on its upper weighing piston 19 into an electrical weighing signal . in fig3 one can recognize that a u - shaped bridge 20 , as seen from the side view , is mounted on the piston 19 . the top u - arch stretches over the weighing cell 18 . one lateral leg of the arch supports a driving motor 21 and a stationary angle gear 22 standing in combination with this , while the other leg supports two bushings 23 and 24 for the two shafts 25 and 26 . the shaft 25 goes through both legs of the bridge 20 , and is supported on its one side in the gear 22 and driven by it . it projects beyond the bushing 23 and carries on this end a cylinder - like cog wheel 27 , that forms one of the turning rollers of a weighing belt 28 . this turning roller is made of metal like a chain belt to be able to withstand high temperatures . the two free tracks of the weighing belt 28 run horizontally . the second turning roll is also constructed like a cog wheel 27 which is supported on the floating shaft 26 . the weighing belt 28 can also consist of two or more small chains arranged in parallel intervals . the parts of the weighing apparatus 14 arranged on a foundation plate 29 are enclosed by a housing 30 with the exception of the weighing belt 28 . the housing consists of two hoods 31 and 32 which are separated from each other and between which is constructed a hallow space 33 . one of these hoods can be provided with a heat insulation . the hollow space 33 is connected to an air intake 34 , through which cool air is blown through the hollow space between the two hoods 31 and 32 . this air goes out preferably in the area of the exit path openings 35 , after it has been circulated around through corresponding conduction paths especially for the cooling of the side facing toward the weighing belt 28 of which the shafts 25 and 26 project through the housing 30 at the exit path openings toward the outside in order to support the weighing belt 28 , which is pivoted loosely , outside the housing 30 . in this way ( i . e . air going out the shafts projecting ) the entrance of dirt is hindered at this one weak point in the housing 30 and a cooling of the weighing belt 28 is brought about . by means of a corresponding ventilation of the inner space , the motor heat which is generated can also be removed . it can be seen from fig2 that the weighing device 17 is so arranged , that the weighing belt 28 points into the angle between the two conveyor belts 13 and 15 . it is arranged with its middle axis just about in the bisection of the angle . the conveying direction of the weighing belt 28 , which is indicated by the arrow 36 , runs from the delivery conveyor 13 to the removal conveyor 15 . the triangular spaces between the conveyor belts 13 and 15 and the weighing belt 28 are filled by the transfer plates 37 . also the triangular space between the two conveyors 13 and 15 and the weighing belt 28 is occupied by a transfer plate 38 . a transfer conveyor 40 in the form of a finger - chain conveyor which runs around the vertical turning rollers 41 and 41 &# 39 ; extends over the delivery conveyor belt 13 , the weighing belt 28 , and the removal conveyor belt 15 . its track 42 , which is turned toward the weighing belt 28 , runs with respect to the conveyor direction 36 of the weighing belt 28 , at a small angle b , such that the running direction of the track 42 and the conveyor direction diverge at the angle b . the driving of the weighing belt 28 is monitored with respect to its number of revolutions by a first tachogenerator 43 seen in fig3 and this number of revolutions is synchronized also with the speed of the drive of the transfer conveyor 40 which is monitored by a second tachogenerator that is not shown . this synchronization is such that the weighing belt 28 has a higher speed than the transfer conveyor 40 by a constant factor . a signal source 44 arranged at any position in the area of the path of revolution of the transfer conveyor 40 is executed as a contact - less feeler for the purpose of operating together with the fingers 45 of the finger - chain conveyor or with other parts which are placed in the intervals between the fingers on the finger - chain conveyor . the weighing apparatus works as follows : the products 12 which have been produced by the automatic glass blowing machine 11 and placed onto the delivery conveyor belt 13 , and run toward the track 42 of the transfer conveyor 40 and because it revolves clockwise , are caught by the fingers 45 and pushed over the first transfer plate 37 onto the weighing belt 28 . thereby , as can be seen in the lower part of fig2 the products rest against the finger 45 as well as on the track 42 . since they are driven by it , they are conveyed in the transfer conveyor direction 36 , when they come onto the weighing belt 28 . as a consequence of the fact that the speed of the weighing belt 28 is somewhat faster than that of the transfer conveyor 40 , the products move a little ahead of the finger 45 . at the same time they move away from the track 42 because of the divergence between the transport direction 36 and the direction of the track at the angle b . therefore , the product 12 stands free on the weighing belt 28 shortly after its arrival thereon so that no falsification of the weighing result can occur . the weight of the bridge 20 , which has been increased by the weight of the product 12 , affects correspondingly the weighing cell 18 , which because of its built - in damping device undertakes a quick transient to the correct weight . shortly before the product 12 has run the full length of the weighing belt 28 , one of the fingers 45 of the transfer conveyor goes past the signal initiator 44 and thereby releases a call - off impulse for the weighing signal . in this moment , therefore , the momentary value of the electrical weighing signal of the weighing cell 18 is taken and shown or analyzed . in the process , indeed , a weighing signal is released , when no product is on the weighing belt 28 , but it is simple to eliminate the resulting weighing signal &# 34 ; 0 &# 34 ; by the determination of an average value . when the product 12 is transported from the weighing belt 28 to the adjoining transfer plate 37 , it becomes slower because it is no longer transported by the weighing belt 28 ; for this reason , it is caught by a finger 45 again , which shoves it over the transfer plate 37 onto the removal conveyor belt 15 , on which the product then goes into the cooling oven 16 . whereas the conveyor belts 13 and 15 and the weighing belt 28 as well as the transfer conveyor 40 can be executed to be sufficiently sturdy and resistant to temperature , as were the construction parts tested in practice , so as to be able to stand up against the extraordinarily high temperatures and the dirt which is generated , this is not the case with the sensitive weighing cell 18 , the electro - motor 21 and the support bushings 23 and 24 for the shafts 25 and 26 of the weighing belt 28 . these are , however , enclosed in the housing 30 and are thereby protected from dirt and air turbulence , as well as protected from the heat by an air - cooled double wall . as already mentioned , air is led into the double wall through the nozzle 34 and goes out by way of the openings 35 . thereby , the heat conduction over the shafts 25 and 26 is also lessened . the weighing apparatus 14 stands , in the arrangement shown , in a place which is not usable in the operation anyway , and can therefore be constructed sufficiently sturdily and enclosed with a housing 30 for which nothing need be spared on the dimensions . the transfer of the articles 12 from the delivery conveyor belt 13 onto the removal conveyor belt 15 which is necessary anyhow , is neither disturbed nor complicated by the weighing process . if it should happen that a malfunction of the weighing device does occur or that a weighing is not necessary at the moment , then the weighing belt 28 can be eliminated from the path of the transfer by means of a pivoting of the transfer conveyor 40 around the axis of the turning roller 41 . this position is represented in fig1 and 2 by dotted lines . it is also to be recognized that in the process , the products 12 are pushed from the delivery conveyor belt 13 to the transfer plate 38 and from this directly , that is while the weighing belt 28 is bypassed , onto the removal conveyor belt 15 . this device is also advantageous when occasional spot checks are to be made with the weighing device . in the example presented , the products 12 arrive on the delivery conveyor 13 in a single file . when in the case of a correspondingly executed manufacturing machine , two rows next to each other arrive , it will be necessary to shift the device as shown and described . then it can be advantageous to provide , in addition to the transfer conveyor 40 , another similarly constructed transfer conveyor whose turning rollers 41 rotate around horizontal axes . such a device is indicated in fig4 . the transfer conveyor 40 shown there can , under certain conditions , be also provided alone or there can be two transfer conveyors of this kind running parallel . the fingers catch from above in this case . the use of two separate weighing belts is also possible . in the usage of the weighing device with an automatic glass blowing machine 11 as described , the weighing signal is the entrance signal for a regulating device 50 that , as is indicated in fig1 affects the automatic glass blowing machine 11 such that it regulates the feed - in elements for the glass to the individual blowing molds as a function of the weight of the products 12 . by this means , it is possible , by way of the weight of the manufactured containers , to keep the capacity and the thickness of their walls precisely constant , and by this means the thickness of the walls can be reduced to the necessary minimum thus saving material . it is also possible to be able to sell to the consumer of the product in the containers in exact proportion . one should also note that the bridge 20 occupies a very stable position as shown in fig3 by the arrangement of the weighing belt 28 and of the motor 21 below the point of support of the bridge 20 on the piston 19 . furthermore , it is a great advantage that the fingers 45 of the transfer conveyor 40 are each in contact with the product 12 only a very short time and no longer touch them during the weighing procedure . this way they have sufficient time to cool down further ; for that reason it becomes possible to provide them with a coating , which avoids change blemishes or reduces them to a minimum . further , the free - supporting bushing of the weighing belt 28 makes easily possible its changing or repair . it is a further advantage that due to the excellent guidance of the products onto the transfer plates , a weighing belt of relatively large diameter can be chosen , which improves the smoothness of the weighing belt &# 39 ; s operation . by eliminating all wobbling tendencies of the products with such a large diameter weighing belt , the weighing results are thereby improved . the invention is especially advantageously mountable in the described possible application in glass manufacturing . it is , however , in comparable circumstances , always usable when products which are transported on belts must be weighed and of great advantage when these products or their method of production , have a high temperature , create a great amount of dirt or produce in other ways , harmful and insufferable environmental conditions for weighing devices . the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof , and , accordingly , reference should be made to the appended claims , rather than to the foregoing specification as indicating the scope of the invention .
