Description




TECHNICAL FIELD




The present invention relates to a vending machine for vending articles, most notably beverage or food containers. More particularly, the present invention relates to a vending machine having a cabinet with a plurality of vertically spaced shelves, and an “X-Y” picker assembly for receiving a packaged beverage from a shelf and for delivering the packaged beverage to a delivery port in a front face of the cabinet, or to another location as desired.




BACKGROUND OF THE INVENTION




Various vending machines are known which dispense articles from shelves or storage bins. Conventionally, the dispensed articles fall, under the influence of gravity, away from the shelf or storage bin. A chute is typically located in the path of the falling article and directs the falling article to a discharge port located beneath the shelves or storage bins.




Such conventional vending machines do not fully utilize the interior space of the vending machine. Since gravity is used to deliver the article to the discharge pork the space adjacent and beneath the discharge cannot be used to store vendable articles. Therefore, the discharge port is typically located in the lower portion of the vending machine, which may not always be suitable for the users.




In such prior art dispensing apparatuses, there may also be multiple escapement mechanisms, one for each row of products, which are configured to dispense one of the products iron the front of each row. As may be understood, such escapement mechanisms tend to add to the cost and burden the reliability of the forty-five (45) separate escapement mechanisms.




Other known devices include U.S. Pat. No. 4,867,628 and German Patent No. DE-U-946212. The U.S. reference shows a dispenser that moves an article in or out of a storage compartment via a bin. The bin is operable in the Z-direction via a slide guide. The German reference apparently shows a dispenser that removes an article from a storage compartment via a piercing device that moves in the Z-direction.




Glass door vendors include a glass door on the front, with the glass door being opened from the front by the servicing personnel. This allows the servicing personnel to access the products through a front opening. Products are also visible by the consumer, which is an advantage. However, packout is also a consideration in the building of the devices, especially if the products are standing upright, and have different heights. In such a situation the highest product on a particular shelf may result in poor packout if other lower products are used within the same shelf. Furthermore, the gear motors are used To drive the coils in each of the product dispensing areas in the glass door vendors again tend to add to the cost and burden the reliability of the overall dispensing apparatus.




However, the glass door vendors do have advantages; when a customer walks up to a glass door vendor, he/she can see whether or not there is product in the machine. If a customer cannot see the product, there may be some hesitation on behalf of the customer to use the vendor. The known dispensing devices described above would not be useful in the glass door vendor applications because The dispensers would block the view of the customer to the products.




Therefore, there is a need in the art for an improved product vending apparatus which allows for viewing of the products, provides improved packout, and accommodates a variety of dispensing schemes, while still remaining cost-efficient and reliable.




SUMMARY OF THE INVENTION




The present invention overcomes deficiencies in the prior art by providing an improved product vending apparatus which allows for viewing of the products, provides improved packout, and accommodates a variety of dispensing schemes, while still remaining cost-efficient and reliable.




Generally described, the invention is directed towards an apparatus for storing and dispensing a plurality of products, the apparatus comprising a frame, a plurality of storage locations for storing the products, a discharge location, and a picking apparatus configured to withdraw the products from any one of the storage locations, transport them singularly for a distance, and dispense them into the discharge location.




Therefore it is an object of the present invention to provide an improved dispensing apparatus and method of using same.




It is a further object of the present invention to provide an improved dispensing apparatus which allows for viewing of the products.




It is a further object of the present invention to provide an improved dispensing apparatus which provides improved pack-out.




It is a further object of the present invention to provide an improved dispensing apparatus which accommodates a variety of dispensing schemes.




It is a further object of the present invention to provide an improved dispensing apparatus which is cost-efficient to manufacture and operate.




It is a further object of the present invention to provide an improved dispensing apparatus which is reliable.











Other objects, features, and advantages of the present invention will become apparent upon reading the following detailed description of the preferred embodiment of the invention when taken in conjunction with the drawing and the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Reference is now made to the drawings, in which like numerals designate like elements throughout the several views shown in

FIGS. 1-5

.




General Discussion of Method and Apparatus




Generally described, the present invention relates to a dispensing apparatus which dispenses products such as cans, bottles, boxes, etc., to a waiting consumer.

FIG. 1

is an illustrative view of one such dispensing apparatus


10


which dispenses a plurality of different products


11


out of various rows I, II, III, and IV, by use of a picking assembly


20


which is part of a X-Y traverse assembly


15


.




Referring also to

FIG. 2

, the picking assembly


20


includes rotating fingers


21


, stationary fingers


22


, and left and right block members


23


,


24


, respectively, each of which engage and move horizontally relatively to upper and lower horizontal rods


30


,


31


.




By rotating the rotating fingers


21


of the picking assembly


20


, the picking assembly


20


can “pick” a product, move the product to a remote location by means of the X-Y traverse assembly


15


, and dispense the product as desired.




The Frame




The frame of the overall dispensing apparatus


10


is shown generally as


13


in FIG.


5


. This frame can be as known in the art in that it can provide an enclosure for containing product as well as a framework for supporting various of the other internal components of the apparatus, such as the X-Y traverse assembly


15


.




The X-Y Traverse Assembly


15






Referring now to

FIG. 1

, the X-Y traverse assembly


15


includes the picking assembly


20


, and also includes upper and lower horizontal rods


30


,


31


, left and right traverse assembly blocks


25


,


26


, and left and right vertical rods


32


,


33


.




The left and right vertical rods


32


,


33


, extend in a generally coparallel fashion, and are configured to allow for relative vertical movement of the left and right assembly blocks


25


,


26


along their respective heights. This can be done by providing an interaction of the rods


32


,


33


and the blocks


25


,


26


such as used in conventional X-Y plotter technology.




The horizontal rods


30


,


31


, have each of their ends mounted in left and right traverse assembly blocks


25


,


26


. Left and right block members


23


,


24


, each engage and are configured to be moved horizontally relatively across the upper and lower horizontal rods


30


,


31


. Again the interaction of the rods


30


,


31


and the blocks


23


,


24


can be such as used in conventional X-Y plotter technology.




The picking assembly


20


is moved along an “X” axis by its relative movement along upper and lower horizontal rods


30


,


31


. The picking assembly


20


is moved along its “Y” axis by parallel movement of the left and right traverse assembly blocks


25


,


26


, along corresponding left and right vertical rods


32


,


33


.




Such movement along the X and Y axes allow for the picking assembly to select (a.k.a. “pick”) products, move to a different location, and subsequently release (a.k.a. “release”) them into a single outlet chute (not shown) or into a six-pack container by use of the guide member


50


shown in FIG.


1


.




Picking Assembly


20






As noted above, one picking assembly


20


is moved along both an “X” axis and a “Y” axis relative to the frame of the apparatus


10


. Referencing

FIG. 2

now for more detail, the picking assembly includes not only the previously-discussed left and right picking assembly blocks


23


,


24


, but also a pair of rotating fingers


21


and a pair of stationary fingers


22


.




The pair of stationary fingers


22


are configured to be mounted one each within corresponding left and right picking assembly blocks


23


,


24


. As will be discussed later, the pair of stationary fingers


22


is configured to provide a “cradle” for the product after it is picked by the rotating fingers


21


but before it is discharged by the picking assembly


20


.




The rotating fingers


21


rotate in a single direction (although it may be reversible) with such rotation being around a central, substantially horizontal, axis. This pair of rotating fingers


21


is used to “pick” product from the front of a row of products, with the rotating fingers


21


passing through the comblike fingers


40


in the shelves


12


discussed below.




Besides providing a picking function, as discussed in detail later, the rotating fingers


21


also provide a “block” to the can behind the target can so that the next can does not roll off the shelf under its own momentum.




The Shelves with the Comblike Fingers




Reference is now made to

FIGS. 1 and 3

, in describing the shelves


12


used to contain the products prior to their dispensing. As may be seen in

FIG. 1

, four rows I, II, III, and IV of products


11


are stored on an exemplary single shelf


12


. This shelf is inclined as known in the art and includes dividers as known in the art to provide a plurality of inclined “chutes”, which allow product, especially round product, to slide or roll down to the front of the shelf under the influence of gravity (spring pressure may be used to assist rectangular or irregular product as needed).




At the front edge of the shelf is provided a comblike lip configuration provided by a plurality of spaced-apart “fingers”, which extend generally upwardly from the front edge of the shelf


12


, to provide a retention feature for the front can in each row so that it will not fall off. This retention feature, however, can be overcome by the use of the rotating fingers


21


as noted above, which pass through the comblike fingers


40


and allow for the frontmost product from a particular row to be withdrawn by the picking assembly


20


.




Under the present invention there may be more space than fingers in the comb mechanism. However, once programmed the gripper device will be “smart” enough to know where to go to pick the product.




One Picking Process




Reference is made to

FIGS. 3 and 4

to describe the relative movement of the rotating fingers


21


as they cooperate with stationary fingers


22


in picking a product


11


.

FIG. 3

is a side illustrative view of a plurality of different products


11


loaded within various shelves


12


A,


12


B, and


12


C, also showing by illustration the relative movement of the rotating fingers


21


as they cooperate with stationary fingers


22


in picking a product


11


and moving it through positions shown as


11


-A,


11


-B, and


11


-C. An alternately sized product


11


′ is also shown to illustrate that the apparatus


10


according to the present invention can accommodate differently sized products.





FIGS. 4



a


-


4




d


are illustrative side views showing sequential steps in the picking process of the rotating fingers


21


and stationary fingers


22


, as a target product


11


is picked, and a “next” product takes its place at the front of the product row.




In

FIG. 4



a


, the rotating fingers


21


are at the “ready” position.




In

FIG. 4



b


, the rotating fingers


21


have rotated from the

FIG. 4



a


position and are passing through the comblike fingers and are contacting the target product


11


.




In

FIG. 4



c


, the rotating fingers


21


have rotated from the

FIG. 4



b


position, and the target product


11


has been removed from its row, and is now being supported by the stationary fingers. At the same time, the rotating fingers


21


are “blocking” the next product which is moving into the place of the now-picked product under the influence of gravity. Such blocking can dissipate the energy in the next product to preclude it from jumping over the comblike lip.




In

FIG. 4



d


, the rotating fingers


21


have rotated from the

FIG. 4



c


position and the product is cradled and ready to be carried by the picking assembly


20


to be discharged at a remote location. The “next” product is now in place to be picked next if so desired.




It should be understood that in some instances it has been recognized that the shelf above the item being picked sometimes assists retention of the item as it is being picked, in that the shelf above blocks the item from falling out of the rotating fingers.




Discharge Options




Once the products have been picked by the picking assembly


20


, they can then be carried by the picking assembly


20


to be discharged at a remote location. Such discharge can take many forms.




One type of discharge can be by bringing the product downwardly until one end contacts a stationary surface, thus tipping the product out of the cradle of the picking assembly


20


such that it can fall under the influence of gravity to a waiting chute or guide member (such as


50


in FIG.


1


).




Alternatively, the product could be lowered downwardly on to an inclined ramp, with the inclined ramp being positioned between the two stationary fingers


22


.




Alternately, one of the stationary fingers


22


could “drop-out”, allowing release of the product without contact with any other device.




Operation of

FIG. 1

Configuration with Other Apparatus Modules




Reference is now made to

FIG. 5

, which shows how one can begin with one machine A, and then the machine can be built upon.

FIG. 5

shows different modules. The first picture shows the concept of an “A” module alone. This “A” module could include just an enclosure, shelves, and an X-Y picker assembly.




The second picture (A+B) shows the A module in conjunction with a base module which allows the cans to come out in the front, in the side, or as desired.




The third picture (A+C) shows the A module in conjunction with a base module which allows the cans to come out one at a time in the front, or a multiple pack including multiple products in an erected container could also be provided.




The fourth picture (A+C+D) shows the A module in conjunction with a base module which allows the cans to come out one at a time in the front, or a multiple pack including multiple products in an erected container provided by an on-site erector D could also be provided.




Alternate Picking Apparatus


120




FIGS. 6-10






Reference is now made to

FIGS. 6-10

, which show an alternate picking apparatus


120


which can be used with an alternate apparatus


200


.





FIG. 6

is an isolated pictorial view of an alternate picking assembly


120


. This picking assembly


120


includes a body


119


, a rotating shaft assembly


125


having two rotating fingers


121


, a stationary support rod


122


, a motor


130


, a beveled gear


140


, a beveled gear


141


, and a pair of bearings


150


.




The body


119


is generally “U-shaped” in transverse cross-section, having a main portion and two sidewall portions extending in the same direction from opposing edges from the main portion. These two sidewall portions are substantially planar and coparallel. The two sidewall portions and the main portion combine to form a partially enclosed concealment space for location of a drive motor


130


and other elements discussed elsewhere.




The stationary support rod


122


is substantially rigidly attached relative to one of the side walls of the body


119


, and is configured to cooperate with the rotating shaft


125


as discussed in detail latter.




The rotating shaft assembly


125


includes two rotating fingers, each designated


121


. When suitably manipulated, these two rotating fingers cooperate to support an elongate product


11


such as those shown in

FIG. 1

, and such as shown in phantom in a cradled position in FIG.


7


.




The rotating shaft assembly


125


is rotatably mounted relatively to the body


119


of the picking assembly


120


by use of pair of bearings


150


. One bearing is located within each of the side walls, and is configured to accept the rotating shaft assembly


125


to allow suitable rotation of the rotating shaft assembly


125


relative to the body


119


.




A beveled gear


141


is rigidly attached to and is part of the rotating shaft assembly


125


, at a location along the rotating shaft assembly


125


intermediate the two bearings


150


. The beveled gear


141


is configured to mate with beveled gear


140


, which is rotatably driven by a motor


130


, such that rotation of the motor


130


causes rotation of the rotating shaft assembly


125


.




By suitable control of the motor


130


as known in the art, the rotating shaft assembly


125


may likewise be suitably controlled, such that its rotational position, rotational speed, and rotational direction may all be suitably controlled via electronics or other suitable means known in the art.




The motor


130


can be any type suitable in the art, but in one configuration is contemplated to be a DC gearmotor or a stepper motor.




The main shaft of the rotating shaft assembly


125


may be seen to be substantially parallel to the stationary support rod


122


, and in the preferred embodiment is substantially level with the rotating shaft


125


.




In

FIG. 6

, the rotating shaft assembly


125


may be positioned in what could be thought as a “ready” position, such position being the position in which the picking assembly


120


is positioned when empty and in transit.





FIG. 7

is another view of the picking assembly


120


shown in

FIG. 6

, except in this configuration, the rotating shaft assembly


125


has been rotated to a different position. This position may be thought as the position in which the product


11


has been picked is “dropped” into the cradle provided by the members


125


,


122


. In this position the previously-described “blocking” feature can likewise be performed by the rotating fingers


121


.




It may be understood that once the product has been rolled in place in the cradle provided by members


125


,


122


, the rotating shaft assembly


125


preferably may be rotated back to the position in

FIG. 6

without disturbing the product cradled thereby. This can be done just before the product gets “stripped”, as noted in more detail elsewhere.





FIG. 8

is a front elevational view of the apparatus of

FIGS. 7 and 6

, with certain dimensions, although not absolutely critical to the operation of the invention, being noted as the result of planning by the inventor.




In

FIG. 8

, dimension A can be 3.375 inches. Dimension B can be 5.658 inches. Dimension C can be 1.600 inches. Dimension D can be 3.0 inches. Dimension E can be 1.175 inches. The diameter “d” of the stationary support rod


122


and the main elongate rod of the rotating shaft


125


can be in each instance 0.250 inches.




Apparatus


200


and The Cable Assemblies





FIGS. 9 and 10

illustrate one means in which the apparatus


120


of

FIGS. 6-8

may be moved about a larger supporting apparatus


200


. This larger supporting apparatus


200


includes a first cable portion


201


, and a second cable portion


202


. Further included is a slide member


210


, a vertical position motor


220


, a horizontal position motor


230


, and a dispensing location


240


. As discussed in detail later, the vertical position motor


220


moves the picking assembly


120


in the vertical direction, whereas the horizontal positioning motor


230


moves the picking assembly


120


in the horizontal direction, all by use of first and second cable portions


201


and


202


.




The first cable portion


201


is substantially endless in function, although in practice it can be a single length of cable, cord, or other suitable flexible material having each of its ends attached to a common movable element. Reference is made to both

FIGS. 9 and 10

to illustrate the path of the first cable portion


201


, which is defined by a plurality of conventional guide pulleys


209


, and a motor


230


pulley, all of which are rotatably mounted relative to the frame of the supporting apparatus


200


. This frame is not shown in

FIGS. 9

or


10


but is generally shown in FIG.


11


. In one embodiment, the ends of the first cable portion


201


are attached to the elongate slide member


210


, discussed below. Operation of the horizontal positioning motor


230


, which includes a drive pulley engaging the first cable portion


201


, moves the picking assembly


120


in the horizontal direction as discussed in more detail below.




The picking assembly


120


is slidably mounted relative to the slide member


210


, such that the picking assembly


120


can slide up and down the elongate slide member


210


, subject to the constraints of the second cable portion


202


as discussed below. Vertical position motor


200


is attached relative to the slide member


210


and moves horizontally therewith.




The second cable portion


202


is substantially endless in its function, although in practice it can be a single length of cable, cord, or other suitable flexible material having each of its ends attached to a common movable element. This common movable element could be the picking assembly


120


, such that rotation of the vertical position motor


220


causes movement, either up or down, of the picking assembly


120


. The second cable portion


202


is supported by two pulleys, a cable guide pulley


203


rotatably mounted to the lower end of the slide member


210


, and a drive pulley being part of the vertical position motor


220


.




By suitable control of the vertical position motor


220


, the vertical positioning of the picking assembly


120


can likewise be controlled.




The elongate slide member


210


has an upper end attached relative to the first cable portion


201


, and a lower portion attached relative to the first cable portion


201


. Referring now also to

FIG. 10

, by use of the direction arrows


250


, one can see that the cable portions to which the slide member


210


is attached move in generally the same direction, such that movement of the first cable portion


201


causes the slide member


210


to likewise move in a particular horizontal direction at the same speed as the cable


201


.




As the horizontal position motor


230


drives the first cable portion


201


, the slide member


210


is likewise moved side-to-side depending upon the rotation of the horizontal position motor


230


. Thus, if one assumes that the slide member moves generally to the right, it may likewise be understood that the picking assembly


120


will also be moved to the right, along with the vertical position motor


220


.




Should the vertical position of the picking assembly


120


desired to be varied, the vertical position motor


220


is similarly operated.




Therefore it may be seen that the vertical position motor


220


moves the picking assembly


120


in the vertical direction, whereas the horizontal positioning motor


230


moves the picking assembly


120


in the horizontal direction.




Use of Dispensing Location




After the picking assembly


120


has picked a product


11


and has cradled it as shown in

FIG. 7

, the picking assembly


120


may then be moved generally towards the dispensing location


240


, for deposit therein to be removed by the consumer.




As may be seen, the picking assembly


120


as shown in, for example,

FIG. 7

, is somewhat of a “cantilevered” design, in that the cradled product


11


is positioned to the side of the body


119


of the device. Therefore, it may be seen that this “cantilevered” design makes it possible for the cradled product (as well as the supporting fingers


120


, a portion of the rotating shaft


125


, and a portion of the stationary support rod


122


), to be inserted into the dispensing location


120


.




Once the cradled product is within the dispensing location


120


, the product may then be withdrawn by the consumer with the product still cradled. However, in the preferable alternative, the product may be “stripped” from the picking assembly


120


by suitable means which causes the cradle product to be stripped off of its cradled position as the picking assembly


120


is withdrawn from the dispensing location


120


and back into its picking zone. The consumer could then reach in and grasp the product. If desired suitable barriers could be provided to prevent consumers from being able to reach in and contact the moving assembly


120


.




It should be understood that the dispensing location


240


can include in inlet flap to allow some separation of the picking zone (which may be refrigerated) to the dispensing zone (which may not be refrigerated). Such a flap (or flaps) could be used to provide the stripping function, by being configured as “one-way” flaps which pivot inwardly into the dispensing location cavity, but not outwardly.




Alternatively, on “interference member” could be selectively moved from above, below, or to the side of the position of the cradled product, to provide a stripping function.




Other Alternates




Reference is now made to

FIGS. 11-12

, which show the apparatus


200


as well as alternate apparatuses


300


,


400


, and


500


.





FIG. 11

is a simplified front elevational version showing operation of the apparatus


200


used with the picking apparatus


120


, mainly for comparison with

FIGS. 12-14

.





FIG. 12

shows an alternate version


300


, which includes the use of a central supporting shaft


301


, which moves a rod


302


along its axis, and has a picking assembly


320


attached to its end. By rotational of the central shaft


301


and extension or withdrawal of the captured rod


302


, the picking assembly


320


may be moved to suitable locations within the rectangle which designates the general picking zone.





FIG. 13

shows an alternate version


400


, showing the use of an articulating arm assembly


401


supporting a picking assembly


420


. The articulating arm assembly is mounted to the frame of the overall apparatus outside of the picking zone.





FIG. 14

shows yet another possible embodiment


500


, in which a telescopic arm assembly


501


supports at its free end a picking assembly


520


but said a telescopic arm assembly


501


is supported relative to the frame of the assembly along pivot point


505


.





FIG. 15

shows a vending assembly


200


contemplated by the configuration shown in

FIGS. 6-10

. This vending assembly


200


includes a delivery port


241


into which the consumer can place his/her hand to withdraw the product from the dispensing location.





FIG. 16

shows a prior art vending assembly


1000


for reference purposes.




As noted above, in another alternate configuration the fingers could be independent with each other and at one point one or the other of the fingers could move upwardly, causing tilting to either side.




A “two way” picker could also be used with a hand-like grip. The products could also be standing when gripped with this type of gripper.




As noted above, an option which may be used with the present invention includes the use of “variety packs”, which can be provided by filling the variety pack with different products within the vendor. The holder can dump products into different slots with in the six pack, and the six pack guide member can include slots to allow clearance of the apparatus.




It may also be understood that some “entertainment value” may be derived from use of the machine. As noted above, the X-Y picker will move in view of the user prior to making its picking selection. If so desired, the X-Y picker could be programmed to “follow” the hand of a user should the user place his or her hand on the front glass. In such a situation, the user could move his or her hand on the front glass, and the X-Y picker could effectively follow the hand. If so desired, the apparatus could also be programmed to select the item corresponding to the point at which the user removed his or her hand from the front glass.




It should also be understood that the vending apparatus according to the present invention could also go through movements while it is not being used. In such an instance, the X-Y picker could move through the X and Y axes (without picking) to draw the attention of the user.




Conclusion




Therefore it may be seen that the present invention provides an improvement over the prior art by providing a vending machine for vending articles, most notably beverage or food containers. More particularly, the present invention relates to a vending machine having a cabinet with a plurality of vertically spaced shelves, and an “X-Y” picker assembly for receiving a packaged beverage from a shelf and for delivering the packaged beverage to a delivery port in a front face of the cabinet, or to another location as desired.




While this invention has been described in specific detail with reference to the disclosed embodiments, it will be understood that many variations and modifications may be effected within the spirit and scope of the invention as described in the appended claims.
