Conveyer 218 comprises that a running roller structure (does not specifically illustrate, but it can contain three running rollers, they are positioned over flexible pipe 220 by quadrature and enter conveyer 218 parts), it be used for flexible pipe 220 move from the direction of basic horizontal along machine 10 inside the top (promptly, at X, in the Y direction) be redirected to the direction perpendicular (that is, in the Z direction) with it.Like this, the free end generation that will impel flexible pipe 220 of moving of conveyer 218 is moved, thereby itself and a selected storage cabinet 216 are axially aligned.Afterwards, a flexible pipe driving mechanism (does not specifically illustrate, but it can comprise " the clamping running roller " of a cover routine work) but driven to order about the storage cabinet 216 that pick-up head 224 is come in and gone out and selected by the motor 508 of a direction, take out the purpose that is stored in commodity wherein thereby reach.In illustrated embodiment, the flexible pipe driving mechanism is installed in the middle of the conveyer 218, but, In yet another embodiment, motor 241 and clamping running roller or other driving mechanism (as articulated jib) can be installed along the length direction of flexible pipe 220 and be moved with other place on this length direction.
This structure, that is, flexible pipe 220 moves in the plane at the X identical with the plane of movement of conveyer 218, Y, has simplified the small-sized flexible pipe location among the present invention and the embodiment of driving mechanism
As previously mentioned, because flexible pipe 220 from its end that is connected with source of suction until form with continuous material till the pick-up head 224 of its other end, so the device of hose storage and/or recovery need be provided during X, Y and Z direction suitably move when commodity are sold operation at pick-up head 224.
Therefore, as shown in Figure 3, an inwall 246 is placed on the next door of the outer wall 248 of cabinet 12 abreast, between outer wall and inwall, to form a hose storage district 222.The area of section in hose storage district 222 is a bit larger tham the area of section of the hose loop that wherein forms.Wall 246 and wall 248 are partly clipped in the drawings, in order to show a flow by gravity that the forms annular take-up device/recovering mechanism 250 that bounces back in flexible pipe 220.Mobile be restricted of annular take-up device 250 in hose storage district 222, sliding hammer 252 pullings that it is had by self to a certain extent, edge along sliding hammer has groove 253, be used to make sliding hammer in hose storage district 222, to keep constant centralized positioning, and be used on flexible pipe 220, providing the tension force of constant " a formation loop ".In addition, can cause the centralized positioning of flexible pipe 220, thereby prevent that flexible pipe 220 from rubbing with the sidewall in hose storage district 222 during X, the Y of pick-up head 224 and Z reorientate process the centralized positioning of the sliding hammer 252 that has groove in the hose storage district 222.In order to prevent flexible pipe 220 clots, the size of sliding hammer 252 is designed to be slightly larger than the diameter of flexible pipe 220, and the width dimensions in hose storage district 222 is slightly larger than the width dimensions of sliding hammer 252.The concrete weight of sliding hammer 252 is problems of design alternative, and fixed, for example, the weight of commodity to be moved is used for the intensity at the motor of Z direction driving flexible pipe according to various factors for it, or the like.In yet another embodiment, also can utilize the bottom that a spring will be slided hammer 252 and cabinet 12 to couple together, thereby increase another tension force for annular take-up device 250.
Should also be noted that this recovery based on gravity/hose storage technology both can satisfy the conveyer 218 storage requirement that move on (left side/right side and front/rear) on X and Y direction, also can satisfy the requirement that pick-up head 224 moves on the Z direction.Certainly, this recovery based on gravity/hose storage technology also can be worked finely in such an embodiment, and in this embodiment, the flexible pipe detent mechanism has adopted R, θ, tongs, articulated jib or other technologies automatically.In addition, for purposes of the invention, illustrated recovery based on gravity/hose storage technology is not essential, can replace above-mentioned technology with an all or part of electrified driving recovery technology fully.
Shown in Fig. 2 and 3, when 223 picked 224 of commodity along its path from storage cabinet 216 when moving to chute 210, it is placed with through being installed in commodity identifications (ID) device 254 in the cabinet 12.The commodity ID device that does not need particular type for the present invention, and restriction according to system, this device can comprise, for example barcode scanner or other light image/pattern recognition system, perhaps even can be anoptic system, such as radio frequency identification (RFID), or be installed in system in the cabinet 12, to discern uniquely and to confirm that the commodity of being sold are exactly selected commodity based on magnetic.The formation of this commodity recognition device is a technique known for those skilled in the art, therefore need not further specifying about this one side.
Other embodiment of aforesaid automatic mechanism is contemplated within the scope of the present invention.For example, pneumatic sensor in the illustrated embodiment that the back will illustrate and vacuum brake also can be applied in the sale equipment with other type robotization steady arm, as, rotary-type equipment (R, θ), articulated jib, draw-tube or tongs system, or the like.
In addition, though in illustrated embodiment, only show a Storage 215, flexible pipe 220 and conveyer 218, but the present invention also can be applied in the middle of the dispenser/commodity processor of the type with a plurality of Storages and/or automatic commodity processing mechanism, for example, two automatic processor structures (vertical or horizontal positioned), each device is respectively different Storages, and (for example one is the chill space, another is non-chill space, perhaps one is used for vertically placing product, and another is used for the horizontal positioned product) service is provided.They in this case, need independent flexible pipe, flexible pipe detent mechanism and hose storage district, though may share a source of suction (for example, the hair-dryer motor 226), airflow sensor device and vacuum brake.In addition, also can only use single flexible pipe, flexible pipe detent mechanism and hose storage district in another embodiment, wherein single flexible pipe can provide service for a plurality of warerooms district.Each robotization commodity processing mechanism can have the commodity ID equipment of oneself, perhaps also can share a commodity ID equipment.
In illustrated embodiment, hair-dryer motor 226 provides a higher relatively airshed and low relatively negative pressure.As the selection of design, hair-dryer motor 226 can comprise a vacuum pump, is used to provide the negative pressure of enough degree, still, because the restriction of size and cost has correspondingly also reduced airshed.Under latter event, the diameter of air hose 220 will be littler than the diameter shown in Fig. 2 and Fig. 3, and in application more of the present invention, this point is particularly important.When picking up flexible packaging, illustrated embodiment is particularly useful, its reason is, in picking up the process of flexible packaging, moment or or even the gas leakage that continues can not cause packing to drop usually yet, meanwhile, owing to have the ability of the object of the multiple shape that can pick up Different Weight and size, so it also can provide great dirigibility.Contain at hair-dryer motor 226 under the situation of a vacuum pump, it both can use separately, also can use with a hutch that links to each other with inhaling hose by valve or air hose, in order to bigger airshed to be provided.In addition, also can unite compressor of use and Venturi tube equipment and produce vacuum.
The functional-block diagram of Fig. 4 shows the general operation of technology many aspects and that obtain implementing according to the present invention in comprising as automatic vending machine 10 such commodity vending machines.As shown in Figure 4, control system 400 comprises a microprocessor 402 and relevant memory circuit 404, and this system is built on the control panel 212.Control system 400 also can suitably comprise the electronic section in other parts of automatic vending machine 10.Comprise ROM and RAM high-speed cache in the memory circuit 404, the former is used to preserve running program (known embedded software is used to realize the control of automatic vending machine 10), and the latter then is used for interim service data and other required data of preserving during system operation.Control system 400 response users to payment and selective system 406 (comprise coin shown in Fig. 1 and bank note mechanism 28 and 30 and selector button 40) operation, operate with user interface and commodity treating apparatus automatic vending machine 10, and then the required commodity of dispensing user.More particularly, when the user utilizes payment and after selective system 406 correctly pays the commodity of its selection, control system 400 will be operated X/Y (left side/right side and front/rear) drive motor 408 so that pick-up head 224 is aimed at the storage cabinet 216 of the commodity of wherein preserving user's selection.Then, control system 400 is installed within the conveyer 218 with one and is connected with the flexible pipe drive motor 410 (Z is to motor) of its motion, flexible pipe 220 is urged to the top of the commodity among the storage cabinet of being aimed at.At pick-up head 224 and appropriate time before commodity to be removed contact (in one embodiment of the invention, there is not cold air in the cabinet 12, then this reasonable time can be to be right after before pick-up head 224 enters cabinet 216, if but cold air is arranged, wish that then this time is only with before required commodity contact, its objective is in order to reduce scattering and disappearing of cold air to greatest extent), control system 400 activates hair-dryer motors 226, thereby provides the rising inspiratory force for pick-up head 224.When position transducer 412 is determined pick-up head 224 and has firmly been contacted with required commodity, control system 400 will be impelled flexible pipe drive motor 410 its directions of counter-rotating, from the storage cabinet of aiming at 216, regaining flexible pipe, and then will select commodity and from storage cabinet 216, extract.Then, conveyer 218 is driven to a position of carrying chute 210 to align with commodity.Along with required commodity 233 216 move to chute 210 along its path from storage cabinet, it will be through commodity ID device 254 to be used for unique identification and to confirm that the commodity of selling are exactly the commodity that the user selectes.When sensor 412 perceive conveyer 218 with carry chute 210 aim at after (in this case, sensor 412 can contain a reed switch that is installed on the cabinet antetheca, and magnet that is installed in the forward position of conveyer 218), control system 400 will be closed hair-dryer motor 226, and the commodity that the forfeiture of vacuum will cause selecting are fallen into the client and fetched district 22.As previous described, frangible and can not fall into and fetch the district or be subjected under the situation of this impulsive force at commodity, the bottom that flexible pipe 220 can be urged to conveying chute 210 commodity that get loose again.Should be noted that position transducer 512 can comprise the pneumatic sensor 229 of connecting box, perhaps in another embodiment, it also can comprise the plunger piston type position transducer that mechanically operated and a pick-up head 224 are relevant.In addition, position transducer 412 also can comprise a reed switch that is installed on the cabinet antetheca, and a magnet that is installed in the forward position of conveyer 218.
As mentioned above, the benefit that the excitation of hair-dryer motor 226 is accurately controlled particularly in, under the situation of cabinet internal refrigeration storage, accurately control can reduce the cooling air amount that hair-dryer motor 226 is provided.In a preferred embodiment, microprocessor 402 will encourage hair-dryer motor 226 when pick-up head 224 arrives required commodity, and be actually when its during at once near required commodity (not shifting to an earlier date), because control system 400 has been preserved the relevant up-to-date information of height with the commodity heap of each cabinet 216.When the operator loaded commodity to automatic vending machine 10, this height was in a predeterminated level by hypothesis.When extracting the commodity trial first time after the Storage is filled, by make pick-up head 224 with the speed that reduces towards the commodity that are positioned at cabinet 216 tops, height and true altitude to hypothesis compares then, and control system 400 just can be confirmed this hypothesis height.Control system 400 can also make pick-up head 224 with higher speed near the commodity in this Storage, and have only and just can slow down when at once will be near " top " commodity in this cabinet.This technology helps to guarantee to make the commodity of storage can not be damaged.
Notice that in another embodiment, the height of each commodity can be optional.A kind ofly need not to know that it is just to open hair-dryer motor 226 before knowing the cargo height of before having sold goods that specific commodity stockpile height just can be controlled the comparatively simple method of the operation of hair-dryer motor 226.The certain height that is kept at the commodity among this heap can be enrolled in the storer of control system 400 in advance, perhaps also can compare and calculate the storage height of next commodity to be sold by the height to previous goods in each storage cabinet and known.
When the machine operator activated " resetting " (not shown) switch, control system 400 adopted above-mentioned height detection technology with automatic defaultly, because it supposes that the operator may change the product height in product load level and each cabinet.
Concerning described each embodiment herein, the excitation that can suppose hair-dryer motor or other air-breathing generation equipment (perhaps its substitute, as utilize the vacuum source of valve working) is equivalent to a rapid item grasp force on the pick-up head 224, that is, and and inspiratory force.
Be connected with a communication system 414 on the control system 400, it is used to far-end that the inventories of commodity and the operation information of automatic vending machine are provided, and allows from afar the operation of automatic vending machine to be controlled.In this, communication system 414 can comprise a coupling arrangement, is used for setting up communication link by wired and/or transceiver interface and remote computer.In addition, communication system 414 can communicate with a plurality of automatic vending machines that other has similar coupling arrangement that are in areal, and utilizes wireline interface or radio communication to communicate between them.Communication system 414 even can also provide with a plurality of by LAN (LAN (Local Area Network)), LAWN (WLAN (wireless local area network)) or WAN (wide area network) and be positioned at automatic vending machine of this area and/or communicating to connect of home server/controller.Remote computer can comprise a database, it can receive and/or accumulate the service data from one or more automatic vending machines, then, other people, as deliver goods driver, machine operator, machine master, product vendor etc., just can visit these data (for example, by the internet, perhaps by wired or wireless connection) by utilizing suitable coding.In addition, far-end also can provide the feedback information that is used to control its operation (as, authorization message) to automatic vending machine and carries out subsequent operation to allow it.
In illustrated embodiment, hair-dryer motor 226 provides a higher relatively airshed and appropriate relatively negative pressure.As the selection of design, hair-dryer motor 226 can provide a negative pressure greatly, and still, because the restriction of size and cost, it has also correspondingly reduced airshed.Under latter event, the diameter of air hose 220 will be littler than the diameter shown in Fig. 2 and Fig. 3, and in application more of the present invention, this point is particularly important.When picking up flexible packaging, illustrated embodiment is particularly useful, its reason is, in picking up the process of flexible packaging, with commodity junction moment or or even the gas leakage that continues can not cause packing to drop usually, meanwhile, owing to have the ability of the object of the multiple shape that can pick up Different Weight and size, so it also can provide great dirigibility.An alternative construction of hair-dryer motor 226 can be equipped with a vacuum pump, and it both can use separately, also can use with a hutch that links to each other with inhaling hose by valve or air hose.In addition, also can unite compressor of use and Venturi tube equipment and produce vacuum.In order to make vacuum pump obtain the operating performance close, just need a hutch and/or a vacuum pump with large-size with conventional hair-dryer motor 226.
Fig. 5 and Fig. 6 show the details according to the air connecting box 229 of principle formation of the present invention and operation, and Fig. 7 shows an embodiment of the connecting rod that can be used for its operation.More particularly, box 229 comprises a shell 504, and it has an air intake opening 506 that links to each other with flexible pipe 220 and a gas outlet 508 that links to each other with hair-dryer motor 226 by flexible pipe 235.As previously described, hair-dryer motor 226 produces a negative pressure (promptly, inspiratory force), this air pressure passes shell 504 in order to producing inspiratory force on pick-up head 224 through port 506 and 508, thereby allows pick-up head 224 and to need the article loosely of processing to be connected.Described according to an aspect of the present invention, the inside of air connecting box 229 comprises a pneumatic sensor structure 600 (being shown specifically) in Fig. 6, and its outside comprises a vacuum brake mechanism 500.Vacuum brake mechanism 500 comprises the baffle mechanism 510 of a rotation, and it is positioned at the top of shell 504.Baffle plate 510 comprises a foam seal spare 512, and it aligns attached to the downside of baffle plate 510 and with it, thereby has covered the aperture 514 (more clearly illustrating in Fig. 6) in the shell 504.Baffle plate 510 comprises that towards last lateral parts, pivot 515 passes wherein, and when an end of a pitman arm 516 is depressed tab portion 518 of baffle plate 510, baffle plate 510 will rotate up around it.When baffle plate 510 rotated up, hole 614 was exposed under the atmospheric environment, caused the quick forfeiture of vacuum in the flexible pipe 220 (that is inspiratory force) thus.In illustrated embodiment, pitman arm 516 is around rotating with the linkage assembly 624 contacted pivots 520 that are arranged in Qianmen (Fig. 1 14).Linkage assembly 724 has been shown among Fig. 7.
Can be clear that more from Fig. 6, comprise a pneumatic sensor structure 600 in the shell 504, it can produce a signal that can change with the air-flow degree of air hose 220 inside.In illustrated embodiment, pneumatic sensor structure 600 comprises two parts switch, first comprises a reed switch 602 that is installed on shell 504 tops, second portion comprises the magnet 604 on the free end that is installed in swing arm 606, the operation of this swing arm meeting very near switch 602 time " triggering " switch 602.Swing arm 606 responds air-flows and swing (seeing arrow 610) around axle 608, is flapped toward port 508 from port 506 by shell 504.During air blast, swing arm 606 is maintained at the direction of basic horizontal, makes magnetic head 604 and switch 6,020 minutes approaching thus, and reed switch 602 is in the close position.Preferably air reflecting plate 612 and 614 is contained in the shell 504, with guarantee to make swing arm 606 during the variations in flow (it may commodity pick-up head 224 with wait that the article of being sold occur before producing enough excellent contact) enough height that can rise to be to finish the proper operation of reed switch 602
Before pick-up head 224 touched commodity packaging, the air blast of process shell 504 can make swing arm 606 essentially horizontally swing, thereby makes reed switch 602 closures.After pick-up head 224 touches article, the surface of article will stop the air intake that enters pick-up head 224.This will cause sharply reducing of shell 504 interior air-flows.The reducing of this air-flow will cause swing arm 606 to lower swing, and reed switch 602 is opened, and then send signal to control system 400.This signal indication pick-up head 224 has produced with article and has firmly contacted, and can begin to make 410 counter-rotatings of flexible pipe (Z) drive motor and activate X and Y drive motor 408, thereby article are removed and be discharged into the dispensing district from the Storage.But the signal that reed switch 602 is produced also Be Controlled system 400 is used for the conveyer 218 that arrives an accurate known location (for example, one " virtual original position " (virtual home)) is checked.In case conveyer 218 arrives the tram of sending objects, its forward position will drive the connecting rod 724 among Fig. 7, and connecting rod 724 links to each other with quick air release valve door and drives its work.Notice that in shell 504, the snap-out release of vacuum will cause reed switch 602 that a signal (because article no longer stop the air-flow that enters flexible pipe 220) is provided once more, this signal can be used for being sold to control system 400 expression article.Therefore, this signal can be used to close hair-dryer motor 226 and start the position that conveyer 218 is back to its " original position ".
Notice that reed switch 602 can be Chang Kai or normally closed type, in other embodiments, reflecting plate 612 and 614 also can not need can need.In addition,, also can adopt the sensor of other type to indicate moving of swing arm 606 though in illustrated embodiment, adopted the switch element of magnetic reed switch as pneumatic sensor 600, as, capacitive character or inductive sensor/switch structure.In addition, also can design the physical construction of other type so that the part of pneumatic sensor is mobile in shell 504, for example, the swing arm of being made by enough soft material 606 can respond the variation of air-flow and move, just as linking to each other with shell 504 by rotating shaft.
According to another aspect of the present invention, because control system keeps following the tracks of (for example moving of flexible pipe 220 and conveyer 218, by detecting) from being positioned at the shaft encoder on each drive motor or the pulse of other distance measuring equipments, the signal that is produced by reed switch 602 when conveyer 218 arrives virtual original position can be used as one and check signal, to guarantee that control system 400 can accurately be counted the motor-driven pulse, and under the situation of needs, also can recalibrate this positioning system according to this virtual original position.
In addition, should note, lose the electric signal that contacts with magnetic head 504 from the representative swing arm 506 of reed switch 602 and also can be provided for control system 400, with as one be used for representing conveyer 218 arrived in the machine 10 the precalculated position (promptly, the position that it is the most forward) electric signal can improve the precision by the position control of 400 pairs of conveyers 218 of control system thus.
As shown in Figure 7, door 14 the top along automatic vending machine 10 is equipped with a door connecting rod 724.Connecting rod 724 comprises: be fixed on the first U-shaped support 723 of door on 14, be fixed on the second U-shaped support 725 on the support 723, and pivot arm parts 726, it rotates around axle 728, and axle 728 is supported by the reverse side of support 725.One end of arm 726 has a compliant member 730, and when conveyer 218 placed commodity to be sold commodity to fetch the top of district and chute 210, elastomeric element 730 can contact (as shown in Figure 1) with the forward position of conveyer 218.The opposite end 732 of arm 726 comprises a pad 733, and it is used for contacting with the part 534 of connecting rod 516 shown in Figure 5, and this part is given prominence to and passed a hole (not illustrating especially) that is positioned at support plate 202 tops (as shown in Figure 2).
Note, comprise a torsion spring (not shown) on the axle 728, it makes arm 726 biasings, thereby end 732 is normally separated with the part 534 of connecting rod 516.In addition, should also be noted that when the commodity of preparing to select when conveyer 218 are released into chute 210 that compliant member 730 is used to provide some extended-travels or tolerance limit in the forward location in the forward position of conveyer 218.
In operation, when conveyer has placed commodity to be sold when getting thing district or chute 210, its forward position will touch the end 730 of arm 726, the end 534 that arm 726 is rotated and make the other end 732 order about connecting rod 516 advances near the pivot 22, and then depress the tab portion 518 of baffle plate 510, and make foam seal 512 rise on the hole 614 in the shell 504 and no longer sealing.Hole 614 packing less pure effects are to make the air pressure in the shell 504 reach balanced rapidly, thereby cause the rapid forfeiture of the inspiratory force of pick-up head 224, and then cause commodity 223 to be released into the client rapidly fetching in the chute 210.
Illustrated embodiment is an example in the particular, also should be considered to predictable to its substantial modifications and conversion.For example, in another embodiment, connecting rod 516 and sealing 512/ baffle plate 510 can be integrated with a mechanism, and in this mechanism, connecting rod 516 will cause hermetic unit on the connecting rod 516 to lose sealing to the aperture in the shell 504 around pivot 520 rotations.For example, connecting rod 516 can be placed with its forward position is rotated along the side slip of shell 504 rather than towards its top.In an alternative, connecting rod 516 slides along a side of shell 504, the side of connecting rod 516 can be meshed and be sealed on the aperture of shell 504 1 sides, and like this, the rotation that it is ordered about by door connecting rod 724 can directly make the aperture on shell 504 1 sides lose sealing.
Another alternative also should be considered, for example, and different types of linkage assembly 724.Such embodiment can comprise the rod of a horizontal positioned, and it contains a straight ends branch to form one " crank ".The end that conveyer contacts this rod can make it produce rotation, rather than in the rotation of using under connecting rod 724 situations.The other end of rod is partly installed corresponding mode and is rotated, thereby depresses the tab portion 518 of baffle plate 510, and commodity are fast released.Can contain a baffle plate 510 that is directly driven by solenoid among another embodiment, when sensor arrived suitable forward position to conveyer, it can be activated.In these alternate embodiments, increase and decrease and to realize specific advantage.For example, door connecting rod 724 can be installed by the top along the front portion of automatic vending machine cabinet 12, rather than is installed on the door 14.But perhaps this is not a preferred positions because it might perturbation operation person to the automatic vending machine cabinet inside work of product filled again.These and other modification all is considered to be included within the scope of the present invention.
In addition, before the bottom that product has been moved to product delivery chute 210 up to pick-up head, do not need under the situation of snap-out release commodity, need a kind ofly to be different from aforementioned connecting rod shown in Figure 7 and to be different from the device that is used for activating snap-out release that can perception conveyer 218 have alignd yet near switch with chute 210.In this embodiment, the snap-out release valve can respond additional moving of conveyer 218 and be activated.For example, can adopt a forward that replaces being transported device 218 through the connecting rod of revising 724 to move the connecting rod 724 of activation, the level (left side/right side) that this amended connecting rod need be transported device moves and activates.Moving horizontally of this conveyer can be carried out after pick-up head arrives chute 210 bottoms at once.
As mentioned above, the present invention by provide for control gear be used for representing shown in the electric signal that changes of inspiratory force on the free end of flexible pipe, thereby all foregoing advantages are provided, for example:
1. encourage a mechanism so that its according to than in pick-up head, discharge gradually inspiratory force faster mode discharge commodity;
2. activate relief valve and need not independent circuit;
3. the technology that low-cost and high reliability and fault-tolerance are provided is to be used for determining whether product or is still clamped;
4. provide feedback information working properly for system controller to show suction mechanism;
