this disclosure describes an exemplary concept and plan of operation for the processing and distribution of milk in an economic , effective and efficient manner and embodiment ( s ) of implementing the exemplary concept and plan by way of particular equipment and facilities . in addition to the foregoing , in its broader aspects , a design and lay - out of a building structure is described , which serves as a distribution point and also as a retail store / restaurant and which is laid out and / or constructed as to most effectively serve the purposes that the processed milk / original milk products may be unloaded from the mobile processing plant at the distribution point or in an adjacent retail store — restaurant ; that the raw milk from a milk truck may be delivered and stored in the embedded milk cooling tank ; that the processed milk / original milk products may be conveniently stored for distribution at the station ; and that the customers may be most effectively served by an automated system or robot at the attached retail store / restaurant . as will be apparent , the concept and implementation thereof makes possible a complete and , in effect , a closed cycle of operation at the distributing station . full automatic vending using an industrial robot as an actual vendor is not only economically efficient as it saves human labor , but also the robot itself may play an important role in marketing and promotion of the system . the use of the term robot is broadly understood to encompass automated systems , as are well known in the industrial arts , and is not limited to a robot with arms and legs , as is the common public connotation . the phenomenon of a direct interaction human - machine in a retail store has never been used in a worldwide range . industrial robots are used mainly in industrial applications such as automobiles etc . if in direct interaction with a human , the human must be properly trained to work with the machine . some robot makers have developed a safety robot concept , which is an industrial robot with safety software ready for direct interactions human - machine . however , there have been only very few limited cases when such robot application was used . there has been one prior suggestion of a robot milk bar which is depicted in cz patent 303 , 571 , filed by the present inventor . in this patent , there is an industrial robot equipped with an end effector which can carry only one cup at a time , which means at least three ( 3 ) times slower operation and less performance , which is not sufficient in real life operation . also , glasses used as packaging for products which is inconvenient due to the fact that they can be easily broken and are hard to sanitize — none of these disadvantages can be accepted by current retail operators , as this solution is not economically efficient and requires much investment into the packagings &# 39 ; automatic sanitation technology . there are also fermentation tanks , but they are also used for pasteurization of milk , which may cause an undesired “ cooked ” taste to the final pasteurized milk product , and their operation is generally less cost - efficient if compared to a high temperature short time ( htst ) plate pasteurizer . the use of steam as a heating medium is currently considered as less - economic and less - convenient , since steam increases the milk temperature too quickly which may change typical milk characteristics and taste . another important distinction of the patent is that its unit is not equipped with the possibility of making the products on stock . rather , its production performance was dependent solely upon the customers who visit the adjacent retail store / restaurant and buy the products there . in contrast , in the current invention , the products are made and distributed also to the adjacent stock and at anytime can be redistributed . these features provide greater economic advantages in comparison to the prior patent approach . the concept of a bar that serves milk was wide spread from 1920 &# 39 ; s to 70 &# 39 ; s of the 20 th century . with a rise of fast food chains and global retail concepts which changed average consumer &# 39 ; s behavior and food preferences , classic milk bars almost disappeared . the milk bar has been present in former middle and eastern europe communist countries until the end of 1980 &# 39 ; s . for instance , the decline of australian milk bars and its reasons are solved in the article http :// www . howretro . com / 2011 / 06 / old - milkbar . html ( published oct . 10 , 2011 ). the brief article on the same issue , for great britain , can be found at http :// hasardheureux . tumblr . com / post / 1262941279 / oncewasengland - black - white - milk - bar ( published oct . 10 , 2011 ). a robot milk bar should play a key role in resurrection of a milk bar concept in the 21 st century with its “ state of the art ” technology . an exemplary robot milk bar described herein resolves in a fully satisfactory manner the problems set forth in the above articles . to that end and more specifically , a robot milk bar can be comprised of four ( 4 ) basic functional parts : a milk processing part with a pasteurizer , fermentation tanks , ice water machine , milk cooling tank , central sanitation “ cip ” unit , pneumatic compressor , pipes and accessories ; a robot filling , packing and vending part with an attached cold storage room and a stock for packaging ; and all these parts together can fit in an area of one thousand ninety one ( 1291 ) ft 2 and can be at least partially interconnected . in one embodiment , raw milk brought by a milk truck is either pumped into the milk cooling tank where it can be stored for up to four ( 4 ) days , or directly to a htst plate pasteurizer . the pasteurizer itself is able to provide three general product outputs : 1 ) to the fermentation tanks ; 2 ) to the pasteurized milk storage tank ; 3 ) to the ice cream base mix tank . after having been processed in the fermentation tanks , the pasteurized milk / basic original cultured milk product is pumped through the plate cooler to at least one storage tank which is located in a cold storage room of the robot filling , packing and vending part , whereat a condensing unit and an ice - water chiller is placed too . the storage tank is directly connected to the fermentation tank while being filled and sanitized . when full , the storage tank is moved and reconnected to the robot filling , packing and vending line and / or stored in a cold room , its content being continuously agitated . said robot line is made of a square robot work area with an industrial robot mounted on the floor in the center of the area . specific pneumatic rotary end effector to hold , carry and release cups are mounted in the end of the robot arm , on the turning disc . the robot work area is from three ( 3 ) sides surrounded by programmable logic controller ( plc ) controlled electrically and pneumatically operated devices such as auto cup dropping stations , auto filling stations , auto cup ( sealing ) alu lid dropping station , auto cup alu lid sealing station , and auto plastic lid dropping and pressing station . there are touch - screen operated payment terminals and vending windows where customers can get packed products . said robot work area is also equipped with a belt conveyor which transports paper cup boxes to the filling position , and when they are filled with milk products , they are transported by the conveyor belt to the cold storage room . a robot milk bar can perform multiple functions at the same time for example , a milk processing , a storage and distribution of milk products , a robot filling , a robot packing and a robot direct vending in the retail store / restaurant part of the concept . the embodiment supports both 1 ) redistribution of processed milk / milk products to retail outlets , 2 ) direct distribution to consumers in the retail store / restaurant . in one embodiment , the robot milk bar contains a robot filling , packing and vending line with a robot work area . said industrial robot is equipped with a food - safety pneumatic end effector with four ( 4 ) grippers to hold and release cups . the robot work area further contains automatic filling machines to fill , for example , pasteurized milk , cultured milk products , ice cream , organic flavor additives such as fruit syrup , jam , jelly , honey , cocoa paste etc ., and of automatic cup dropping machines , and of an automatic seal lid dropping machine , and of an automatic cup sealing machine , and eventually of an auto plastic lid dropping and pressing machine . the industrial robot may be equipped with a sensor to detect objects in its work range . vending windows and payment terminals can be located in the retail store / restaurant part . said robot puts packed products into the vending windows . the payment terminals are touch controlled and provide user friendly interface for consumers . there are multiple payment options enabled such as coin accepting , bill validating , bank card payments , smart phone online / offline payment . an embedded microprinter prints out the bill per each purchase realized . in a three - step full automatic vending procedure , at first consumers select the product they like while being clearly informed on the price , second they select the most convenient payment method and pay , and third they get a receipt with an id number and a bar code , and last when their id is visually or audibly announced via a led panel , they can go to the vending window and get their ordered products from the robot . most of the parts of the exemplary system are fully automated and controlled by plc units . it is estimated that only two ( 2 ) people are needed to operate the whole system . thanks to the state of the art in automation , the retail store / restaurant may be open 24 / 7 . in one embodiment , there can be at least 40 seats for consumers , a small restroom with a chemical or water flush toilet , and a children &# 39 ; s corner in the retail store / restaurant , if so desired . in one or more embodiments , such a robot milk bar provides several benefits : milk processing and multiple distribution is realized in one place ; mobility ; operability by a wide range of subjects from farmers to retailers ; minimizes human labor ; a state of the art in automation ; global use ; health food . the embodiment ( s ) bring a new use of an industrial robot arm in food retail industry while developing a high level human - machine interface , and achieves the economic result and objective of delivering a raw product directly from the point of production from the farm to the point of sale , in bulk and directly to the ultimate consumer , without having to go to an intermediate processing plant and then be redistributed . with some modifications , the embodiment ( s ) can be used to process and distribute other kinds of food or casually non - food products . referring now to the drawings , it should be noted that the exemplary robot milk bar of the present invention can be disposed in four ( 4 ) modified forty ( 40 ) foot containers and functionally is also divided into four ( 4 ) parts . of course , other sizes and configurations are possible . in one embodiment , there is a cloakroom , bathroom , lab , and a central power -

based detergent from the cans 93 , an exit solenoid valve 95 , a sanitation valve 96 for the circuit one ( 1 ) and a sanitation valve 94 for the circuit two ( 2 ). the valves 95 , 96 and 94 should be automatically controlled . in the circuit one ( 1 ) the cleaning solution , from a central sanitation tank 36 , is sucked in the system by the product filling pumps 27 , 26 and flows in the cip line 37 through the manually opened sanitation valves 88 , while the product outlet valves 22 are closed , directly to the hoppers of automatic filling stations 30 and by its filling heads 65 out to the cip return line 89 and by gravity flows back to the tank 36 . in the circuit two ( 2 ) the cleaning solution is circulated by the cip pump 39 in the cip line 38 , then it is sprayed by spraying nozzles installed on top of hoppers of the automatic filling stations 30 , and it also flows into the liquid flavour storage tanks 28 where it is sprayed by spraying heads 15 and via the outlet valve 29 and product filling pumps 27 goes into the automatic filling station 30 hoppers and through the filling heads 65 it is flown by gravity back to the tank 36 . the following cases , which in describe the manner in which raw milk can be processed in the robot milk bar , are for illustrative purposes and are understood not to be limiting to how the embodiment may process raw milk , as multiple other approaches may be devised , according to design preference . raw milk is pumped from a milk truck by a hose which is connected to the system at the input manual butterfly valve 57 . raw milk is firstly pumped into the milk cooling tank 15 through the pneumatic butterfly valve 6 , after the level sensor 59 signals that the tank 15 is full the valve 6 is closed , and some volume of raw milk can be pumped through the pneumatic butterfly valve 58 and through the milk pump 7 directly to the balance tank 53 of the plate pasteurizer 8 . the valves 6 and 58 are controlled by the pasteurizer 8 central programmable logic controller ( plc ). the operation of the pasteurizer 8 is conventional , milk is pumped from the balance tank 53 through the heating section of the desk heat exchanger to the flow divert valve where it is returned back to the balance tank 53 unless the required pasteurization temperature of approximately seventy two ( 72 )° c . and holding time of approximately twenty ( 20 ) seconds is reached , then a flow divert valve directs the milk through the cooling section 34 to another flow divert valve and out of the pasteurizer when the required product outlet temperature of approximately four ( 4 )° c . is reached , or the milk overflowed is returned to the balance tank 53 . the cooling is made at the integrated heat exchanger 34 by ice water which is made in the ice water machine 33 and is circulated by an ice water pump 54 through the ice water lines . pasteurized milk at approximately four ( 4 )° c . is then transported through the open pneumatic butterfly valve 9 directly to the pasteurized milk storage tank 18 while the valves 60 , 61 , 62 are kept closed . pasteurized milk is stored at a storage tank 18 in the cold storage room 66 of the robot filling , packing , vending and storage part 2 at temperature of approximately 4 - 8 ° c . the storage tank 18 is connected via top - lid mounted manual butterfly valve 63 and the stainless steel line 10 to the pasteurizer 8 . said storage tank 18 is then moved to the robot filling , packing and vending line 52 where is connected via an exit manual butterfly valve 22 to the line 64 and pasteurized milk is then transported by a product pump 27 into the hopper of an automatic filling station 30 . plc commands the robot 41 to go to the position of auto cup dropping stations 42 whereat a cup is dropped into the gripper 48 of the robot end effector 46 . the robot end effector 46 is mounted on a robot 7 th ax flange 47 , and has four ( 4 ) robot grippers 48 which are operated by pneumatic cylinders 49 controlled by electromagnetic 24vdc valves 50 . each gripper 48 is also equipped with an object detection analog sensor 66 . the cup held by the gripper 48 , the robot 41 moves to a filling head 65 of the automatic filling station 30 , when the gripper 48 with a cup is in the filling position , the robot 41 signals to the plc , which switches the auto filling station 30 on , to fill a preset dose of the pasteurized milk , the auto filling station 30 signals to the plc when the operation is finished . the auto filling station 30 works in a known manner using two actuated pneumatic cylinders controlled by two electromagnetic 24vdc valves while the dose level is manually preset on the dosing cylinder . the cup with pasteurized milk is then carried by the robot 41 to the auto seal lid dropping station 43 whereat a seal lid is dropped onto the cup still held by the gripper 48 . the specific operation of auto seal lid dropping station 43 of the present invention is such that a pneumatic cylinder is actuated and turns the suction grabbing head upwards towards a seal lid down in a vertical hopper , the vacuum is activated by the pneumatic ejector and the suction grabbing head , with a seal lid sucked on , goes back downwards until a seal lid is in the centered position above the cup rim . then the vacuum is switched off . in next step the robot 41 moves to the auto lid sealing station 44 where the seal lid is sealed onto the cup rim . the auto lid sealing station 44 is a conventional designed device with one pneumatic cylinder , controlled via a solenoid valve , which moves the sealing copper head consisting of heating elements down towards the position where the cup with a lid on is held by the gripper 48 , while pressing down and heating at preset sealing temperature , the seal lid is sealed tight onto the cup rim . this operation finished , the robot 41 is commanded to move to the auto plastic lid dropping & amp ; pressing station 45 wherein a plastic lid is put onto the sealed cup and pressed down so the lid be fitted over the cup rim . the station 45 operates in a known manner using two pneumatic cylinders , actuated via two solenoid valves , while one of the cylinders divides the plastic lid from a column and makes it out , and the other cylinder is used to press down a dropped lid onto the cup . that is the end of a filing and packing procedure . from this point on , packed cups are either dropped into the carton cup box 67 and transported by the conveyor 31 to the cold storage room 66 , or put into the vending window 32 whereat customers can pick it up . in the first case robot 41 , ideally carrying in all four ( 4 ) grippers 48 closed / sealed cups with milk products , is commanded to move to a position above the belt conveyor 31 , where are placed and transported carton cup boxes 67 . when three ( 3 ) carton cup boxes 67 are in the robot 41 cup dropping position , which is defined by signals from optical sensors 68 and physically made by on - belt mounted dividers 69 , the robot is initiated to go with a gripper 48 above the cup hole in the carton box 67 and the cup is dropped into the hole by releasing of gripper 48 jaws . each position / cup hole which has already been filled with a cup is stored by the plc application , when all three ( 3 ) carton cup boxes 67 are filled with cups , they are transported by the belt conveyor 31 to the cold room 66 and stocked . in the second case , prior to a direct robot vending to consumers , a consumer &# 39 ; s order must be made at the order / payment terminal 78 whereas a receipt with an id and bar code is printed out , then the robot 41 , carrying cup ( s ) with ordered products , moves to the vending window 32 . the vending window 32 is provided with two ( 2 ) safety transparent sliding windows 70 with embedded sliding rollers 74 , two ( 2 ) pneumatic cylinders 72 with a control solenoid valve 73 , a germicidal lamp 76 and reflective light sensors 75 . the safety window 70 on the side of a robot work area 52 is slided up as soon as the robot 41 gripper 48 is moved into the vending window 32 and the cup is dropped into the position defined by a reflective light sensor 75 . cup ( s ) in position , the gripper 48 is moved out of the vending window 32 , the safety window 70 is slid down and a particular order id is announced on the lcd displays 77 . the consumer with such id on the receipt may approach the vending window 32 and have the barcode reader 71 check the barcode printed on her / his receipt , the barcode read , the safety window 70 on the side of a retail store 3 may be slid up and the consumer can take the cups out of the vending window 32 , when an inner space is empty ( cups have been take away ), which is recognized by the reflective light sensors 75 , the safety window 70 is slid down , the germicidal lamp 76 is switched on for a preset time and , when switched off , the vending window 32 is empty and ready for next customer . the procedure is almost the same as in case 1 with the difference that there is also a liquid flavour portion added to the pasteurized milk by an automatic filling station 30 . the procedure is such as in case 2 with the difference that there is also an ice cream portion added to the flavoured pasteurized milk by another automatic filling station 30 . the procedure is almost the same as in case 1 with the following differences : pasteurized milk , leaving the pasteurizer at temperature which may vary from approximately twenty - five ( 25 ) to approximately forty - five ( 45 )° c ., is then transported through the open pneumatic butterfly valve 61 and product inlet valve 82 directly to the ice cream base mixture tank 13 while the valves 60 , 9 , 62 are kept closed . the capacity of the base mixture tank 13 is typically one hundred ( 100 ) liters , but may vary . ice cream base mixture ingredients are added / dosed to the pasteurized milk and the desired base mix is constantly agitated while getting cold to four ( 4 ) to eight ( 8 )° c . base mix is then pumped out by the dosing product pump 19 and flown through the no - return valve 23 into the gelato / ice cream making machine 24 . the ice cream making machine 24 is a component which may be of type well known commercially with two principle requirements : it must combine functions of a batch pasteurizer ( heating ) and a batch freezer ( freezing ), and must have two ( 2 ) processing speeds — low for italian gelato , and high for overrun american ice - creams . the ice cream and / or gelato is typically processed in ten ( minutes ) and desired final flavour is added to the base mix before the processing starts in the machine 24 . then the product outlet valve 25 is opened and final product is pumped by , preferably , a piston pump 26 into the hopper of one of automatic filling stations 30 . the rest of the procedure is same as in case 1 , only with a modification that the ice cream / gelato must be kept filled and packed until the hopper of automatic filling station 30 is empty . the reason is that this product melts quickly . the procedure is almost the same as in case 1 with the following differences : the operation of the pasteurizer 8 is conventional , milk is pumped from the balance tank 53 through the heating section of the desk heat exchanger to the flow divert valve where it is returned back to the balance tank 53 unless the required pasteurization temperature of approximately eighty - three ( 83 )° c . and holding time of approximately twenty ( 20 ) seconds is reached , then a flow divert valve directs the milk through the cooling section 34 to another flow divert valve and out of the pasteurizer when the required product outlet temperature of twenty - five ( 25 )° c . is reached , or the milk overflowed is returned to the balance tank 53 . pasteurized milk , leaving the pasteurizer at temperature of twenty - five ( 25 )° c ., is then transported through the open pneumatic butterfly valve 60 and product inlet valve 84 directly to the fermentation tank 14 while the valves 61 , 9 , 62 , and also the sanitation valve 9 , are kept closed . the yogurt cultures , either in form of liquid or powder , are dosed into the fermentation tank 14 and the agitation is started . the tank is also equipped with a temperature sensor 56 , and level sensors 55 . the temperature of cultured milk must be kept constant of approximately twenty - five ( 25 )° c . during the whole fermentation period which typically takes about approximately ten ( 10 ) to twelve ( 12 ) hours . the fermentation temperature may also vary from approximately twenty - five ( 25 ) to thirty ( 30 )° c . fermentation finished , the product is flown out through the open product outlet valve 20 , and a product pump 16 . to get a required storage temperature of approximately four ( 4 ) to eight ( 8 )° c ., the product flows through the plate cooler 17 , which is connected to the ice water machine 33 . thereafter , the cold product flows via the product inlet valve 21 ending in the product storage tank 18 . the rest of the procedure is the same as in case 1 . the procedure is such as in case 5 with the difference , that there is also a liquid flavour portion added to the product by an automatic filling station 30 . the procedure is such as in case 5 with the following differences : pasteurized milk , leaving the pasteurizer at temperature of approximately forty ( 40 ) to forty - five ( 45 )° c ., is then transported through the open pneumatic butterfly valve 60 and product inlet valve 84 directly to the fermentation tank 14 while the valves 61 , 9 , 62 , and also the sanitation valve 9 , are kept closed . the temperature of cultured milk must be kept constant of approximately forty ( 40 )° c . during the whole fermentation period which typically takes approximately twenty ( 20 ) to twenty - two ( 22 ) hours . the fermentation temperature may also vary from approximately thirty - eight ( 38 ) to forty - five ( 45 ° c . the rest of the procedure is such as in case 1 . the procedure is such as in case 7 with the difference , that there is also a liquid flavour and / or ice cream portion added to the product by automatic filling stations 30 . what has been described above includes examples of one or more embodiments . it is , of course , not possible to describe every conceivable combination of components or methodologies for purposes of describing the aforementioned embodiments , but one of ordinary skill in the art may recognize that many further combinations and permutations of various embodiments are possible . accordingly , the described embodiments are intended to embrace all such alterations , modifications and variations that fall within the spirit and scope of the appended claims . furthermore , to the extent that the term “ includes ” is used in either the detailed description or the claims , such term is intended to be inclusive in a manner similar to the term “ comprising ” as “ comprising ” is interpreted when employed as a transitional word in a claim .
