Abstract
A vending machine for increasing consumer interest in the vending process and vended product includes a tipping mechanism. The tipping mechanism is positioned at a first end of a shelf, and modifies the orientation of an article being delivered from the shelf to a conveyor. The tipping mechanism causes the article to be tipped from an upright orientation to a perpendicular, lateral orientation. The tipping mechanism includes a ramp supported by the shelf, a spacer that provides the ramp with an incline from the shelf, and a product rotator extending from the shelf toward the conveyor. The conveyor then delivers the article to a vend port, where it is dispensed in the upright position. The conveyor may be mounted on internal elevator that carries the conveyor between one or more shelves and the vend port. A transparent window is provided on the face of the vending machine whereby a consumer can view the dispensing operations.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a vending machine having an elevator for transporting products to a vend port. A transparent window is provided in the face of the machine such that the consumer can see the dispensing operation.




2. Description of the Background Art




Conventionally vending machines have a closed front such that the internal operation of the machine is not visible to the consumer. Conventional vending machines which do have transparent faces which drop articles into a bin in the lower front portion of the machine. The consumer can then reach into the bin and withdraw the products after viewing the vend operation. However, for certain products, such a vending operation is unacceptable. For example, if beverages, and in particular, carbonated beverages, were to be dispensed, this dropping operation would unsatisfactorily shake-up the product.




Other vending machines are known wherein an internal elevator lowers articles to a discharge port. For example, U.S. Pat. No. 4,108,333 discloses a vending machine with an interior elevator for lowering selected articles from a storage shelf to a vend port. The operation is visible through a front window of the vending machine. This arrangement, however, is primarily used for food products, such as sandwiches, salads, lunch platters and dessert items. These items will slide onto the elevator from their storage shelf. Because the items generally have a low center of gravity, they will not tip over. However, when dispensing certain items such as beverage containers, the center of gravity is higher than that contemplated for items dispensed in this U.S. Pat. No. 4,108,333. Thus, if beverage bottles, cans or juice boxes were attempted to be dispensed from this known vending machine, they would likely tip over. Moreover, no provision of horizontal movement of the elevators is provided in this known machine and as such, a rather large and awkward vend port is required.




Accordingly, a need in the art exists for a simple and effective transparent front vending machine that avoids the drawbacks of the prior art machines. This vending machine should increase consumer interest in the vending process and the vended product in order to thereby increase sales.




SUMMARY OF THE INVENTION




Accordingly, the primary object of the present invention is to provide a transparent front vending machine that will display the vending process to attract consumer interest.




A further object of the present invention is to provide a vending machine that has an interior elevator that moves the product both vertically and horizontally.




Still another object of the present invention is to provide a vending machine with an elevator that has either a powered conveyor or a tilt slide mechanism for moving vended objects to a vend port.




A further object of the present invention is to provide a vending machine that can dispense products, such as beverage cans or containers, in a desired orientation without unnecessarily shaking them.




To this end, a further object of the present invention is to provide a vending machine that can dispense elongated products in an upright position, if so desired.




Yet another object of the present invention is to provide a vending machine which will fully display all rows of items to be vended and wherein the vending mechanism will not obstruct this display.




Yet another object of the present invention is to provide a method for dispensing articles which will provide an attractive display for generating consumer interest in the vended product.




Still another object of the present invention is to provide a vending machine which is simple to operate and easy to maintain.




These and other objects of the present invention are fulfilled by providing a vending machine comprising at least one shelf for holding articles; an elevator vertically movable relative to the at least one shelf, the elevator having a bottom member; a conveyor mounted on the elevator for transporting articles from the at least one shelf, the conveyor being horizontal, articles on the conveyor being movable relative to the bottom member of the elevator during transport by the conveyor, both the conveyor and the bottom member of the elevator being vertically movable with the elevator; and a vend port for receiving articles from the elevator and for discharging articles from the vending machine, the horizontal conveyor enabling articles to remain in an upright position during transport to the vend port.




Moreover, these and other objects of the present invention are further provided by a vending machine comprising at least one shelf for holding articles; an elevator vertically movable relative to the at least one shelf, the elevator having a bottom member, articles being deliverable from the at least one shelf to the elevator in a first direction; a conveyor mounted on the elevator, the conveyor being movable relative to the bottom member of the elevator, the conveyor being movable in a second direction which is perpendicular to the first direction, both the conveyor and the bottom member of the elevator being vertically movable with the elevator; and a vend port for receiving articles from the elevator and for discharging articles from the vending machine, the vend port being in a front face of the vending machine, the first direction being a direction toward the front face of the vending machine.




Additionally, these and other objects of the present invention are fulfilled by a method of vending articles from a vending machine comprising the steps of displaying articles on the shelves of the vending machine; releasing a selected article from one of the shelves to an elevator within the vending machine; vertically transporting the selected article on the elevator within the vending machine; horizontally transporting the selected article on the elevator, the selected article moving relative to a bottom member of the elevator; discharging the selected article from the vending machine; and continually displaying the selected article during the steps of releasing, vertically transporting and horizontally transporting, the selected article being visible through a window provided in the vending machine.




In another aspect, the vending machine includes a shelf for holding articles in a substantially upright orientation and a tipping mechanism positioned at a first end of the shelf. The tipping mechanism modifies an orientation of an article being delivered from the shelf to a conveyor. The substantially horizontal conveyor is positioned adjacent the first end of the shelf and receives the article delivered from the shelf. The vending machine also includes a vend port for receiving the article from the conveyor and accommodating the discharge of the article from the vending machine in a substantially upright orientation.




In yet another aspect, a method of vending articles from a vending machine includes providing articles on a shelf of the vending machine in a substantially upright position and tipping the articles as they reach an end of the shelf proximal a conveyor within the vending machine. The method further includes delivering an article from the shelf to the conveyor, horizontally moving the conveyor to orient the article in a second position substantially perpendicular to the upright position, horizontally transporting the article on the conveyor within the vending machine, and discharging the article from the vending machine in the substantially upright position.




Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.




Referring in detail to the drawings and with particular reference to

FIG. 1

, a first embodiment of the vending machine


10


of the present invention is shown. This vending machine


10


has a transparent window


12


through which the operation of the vending machine can be viewed. In the disclosed embodiments, the window


12


occupies a majority of the area of the front face of vending machine


10


. Of course, the size of this window


12


could be varied. Any suitable material can also be used for this transparent window


12


, such as glass or plastic. Moreover, the window can be omitted such that the internal operation of the machine would not be seen. In most situations, however, visibility of the machine's internal operation will draw consumer interest and therefore, increase sales. Accordingly, provision of the window is a good sales technique. Moreover, the window allows ready inspection of the machine such that restocking and maintenance operations are facilitated. While a window


12


is contemplated, the glass or plastic could be omitted such that the face of the machine would be open. However, in most situations, an open front would be unsatisfactory because a barrier is normally needed between the products to be vended and a consumer.




In the first embodiment of the vending machine


10


as shown in

FIG. 1

, a front face


14


of the vending machine is curved. The window


12


could also be flat or curved independently of or in correspondence with the face of the vending machine


10


. As will been seen in later versions, this face can be flat. It should further be appreciated that while a certain curvature is shown in

FIG. 1

, other curvatures can be used. For example, the convex and concave portions of the front face of the vending machine can be switched or multiple undulations could be provided along the face of the vending machine. Moreover, the face of the vending machine can be curved about a vertical instead of a horizontal axis, if so desired. Many different configurations for the machine face are possible.




In the front face


14


of the vending machine


10


, a vend port


16


is provided. While this vend port


16


is shown in a lower right-hand position of the vending machine


10


, its location can be changed. As will subsequently be explained, an elevator (not visible in

FIG. 1

) is provided within the vending machine


10


. This elevator could therefore lift the articles to be dispensed from any suitable height for vending. In fact, multiple vend ports could be provided such that the height of the vended item could be based on the height of the user receiving the product. Moreover, depending on type of application, the particular location of the vend port could varied if so desired. Not only could the height of the vend port be varied, but this vend port could be located on the right-hand side (as shown) or the left-hand side or centrally located in the vending machine


10


. Thus, it should be appreciated that due to the use of an elevator which is both vertically and horizontally moveable as will be described below, great variety can be had in placing the vend port


16


.




The vending machine


10


as shown in

FIG. 1

has a curved front face


14


, which can be a pivotable door


18


. This door


18


would be pivoted to an open position for loading of shelves


20


in the vending machine. For example, in

FIG. 1

, the door could pivot about a vertical axis at the left-hand corner. In this situation, the entire face of the machine would constitute the door. Alternatively, the panel covering the vend port


16


on the right side of the machine face could be separate from the door and would therefore stay in place when pivoting the door


18


. Other door arrangements are possible.




In

FIG. 1

, five shelves


20


are shown in the vending machine


10


. It should be appreciated, however, that any number of shelves can be used. Moreover, any number of rows of items can be provided on the different shelves of the vending machine. It is possible that the heights of the shelves could be varied and that the spacing between shelves could be non-uniform. Because an elevator is used within the vending machine that will be described below, great variety can be had with the positioning of the storage shelves


20


. It is contemplated that forty-five facings can be provided due to the number of shelves and rows of items. Thus, many potential varieties or brands of products can be displayed and dispensed from machine


10


. This provides many choices for the consumer. Moreover, while beverage containers are contemplated as being vended, it should be appreciated that beverages in cans, bottles, two liter bottles or any other suitable size can be handled by the vending machine


10


. In addition, products other than beverages could be dispensed from machine


10


.




Behind the face


14


of the vending machine is a vending machine housing


22


. The shelves


20


extend into this housing


22


. Conventional vending machine components, such as a condenser, can be provided in this housing


22


. The housing


22


rests on two feet


24


as shown in

FIG. 1. A

covering can be provided to hide these feet


24


. Rather than using two feet, four feet at each of the corners could also be used or any other suitable arrangement can be used as so desired.




On the top of the pivotable door


18


, a side panel


26


is provided as seen in

FIGS. 1 and 4

. This side panel


26


can be hinged to the vending machine housing


22


about pivot


28


as seen in FIG.


4


. Alternatively, this side panel


26


could be hinged to the door


18


. As seen in

FIGS. 1 and 4

, the contour of the side panel can match the contour of the face of the vending machine. Different embodiments of the side panel are seen in

FIGS. 1 and 4

with the rear of the side panel is curved in FIG.


1


and the rear of the side panel is straight in FIG.


4


. This variation illustrates that different configurations for the side panel are possible.




Turning now to

FIG. 2

, operation of the elevator


30


will be described. This elevator


30


is not visible in FIG.


1


. Pending U.S. application Ser. No. 09/045,005, filed Mar. 20, 1998 by A. Rudick, P. Carlson and T. Howell discloses a vending machine with an interior elevator. The entire contents (and not just the disclosure of the elevator) of this pending application Ser. No. 09/045,005 are incorporated herein by reference. In

FIG. 2

, the first embodiment of the elevator


30


includes a horizontal conveyor


32


. The elevator


30


′, which will be described with reference to

FIG. 6

instead, uses a tilting elevator bed. The conveyor


32


in

FIG. 2

is a belt conveyor. However, a conveyor consisting of a series of links or jointed segments could instead be used. Any known type of conveyor


32


can be used in the vending machine


10


of the present invention. An alternate elevator design will be described hereinbelow with reference to

FIGS. 6-10

. Also, a series of roller conveyors with a pusher bar, a series of linked cars in a train or a single shuttle car could be used as a conveyor.




A drive


34


is provided for moving this conveyor


32


. In

FIG. 2

, the conveyor


32


moves a selected article


36


horizontally. The top surface of the conveyor


32


is flat and horizontal in order to convey the selected article


36


in an upright position. Of course, this conveyor


32


could be inclined or could be a gravity-feed conveyor. Such a gravity-feed conveyor could not include a roller conveyor. However, when conveying articles


36


such as beverage bottles, an inclined conveyor has a disadvantage in that articles could tip due to their relatively high centers of gravity. It is therefore desirable to use a flat conveyor. As noted above, many different types of conveyors are suitable for use in the vending machine


10


of the present invention.




As indicated by arrow


38


, the selected article


36


is discharged from a shelf


20


onto the top surface of conveyor


32


. The article


36


is then moved in the direction of arrow


40


. The conveyor will wrap around end rollers


44


and


46


as indicated by arrow


42


. Thus, an endless conveyor is provided in FIG.


2


. Known release mechanisms are provided at the end of each of the shelves


24


releasing a single item to the conveyor


32


. Of course with suitable programming, multiple items can be vended simultaneously to the conveyor


32


in order to discharge a plurality of item. However, in normal operation, a single item will be vended for each use of the vending machine


10


.




In

FIG. 2

, only a single shelf


20


is shown for clarity. Of course, a plurality of shelves are contemplated as being used in the machine. Also, in

FIG. 2

, five rows of items per each shelf


20


are shown. Of course, different numbers of rows can be provided per shelf as discussed above.




In

FIG. 2

, dividers


48


are shown for separating the different rows of articles. These dividers


48


can also be omitted. The selected article


36


in

FIG. 2

is a beverage bottle. The instant invention is also suitable for dispensing beverage cans, juice boxes, large beverage containers, such as two-liter bottles, or any other suitable item. The instant invention is particularly suitable for dispensing elongated items that should remain in their upright position during vending.




A motor


50


is shown in FIG.


2


. This motor


50


is connected to the four corners of the elevator


30


by four cables


52


. A guide rail


54


is also indicated in

FIG. 2

for stabilizing the vertical movement of the elevator


30


. While only one guide rail


54


is shown in

FIG. 2

, it should be realized that a guide rail is provided on the left-hand side of the elevator as well (but is not shown). Of course a single guide rail


54


, four guide rails or any other combination of guide rails could be used. Other types of stabilizing devices could be used for aiding in the vertical movement of the elevator


30


.




A control wire


56


is shown extending from the drive


34


for the conveyor


32


on elevator


30


. This control wire


56


is operatively connected to the controller for the vending machine. As an alternate design, the wire


56


could extend downwardly from the elevator


30


. The control signals for the drive


34


can be transmitted through this control wire


56


. Due to the coiled nature of the control wire


56


, vertical movement of the elevator


30


can be easily accommodated.




A guide roller


58


is shown in the upper left-hand corner of the vending machine


10


. The left-hand elevator cables


52


pass over this guide rail


58


. Instead, a two guide sheaves or other suitable guide can be provided. The right-hand cables


52


also have such a suitable guide.




While cables


52


are shown extending to each side of the elevator, the provision of suitable guides such as guide rails


54


on the front corners could lend the elevator


30


to only having a single cable


52


or a cable only attached to each side of the elevator


30


. Nonetheless, in order to provide a smooth lifting and lowering operation, cables


52


on each side of the elevator are preferred.




In

FIG. 2

, the selected article


36


is shown being dispensed from the selected row on shelf


20


. A guide (not shown) can be provided to aid in the transition from the shelf


20


to the conveyor


32


. After loading the conveyor


32


and before the article


36


is moved in the direction of arrow


40


, the elevator


30


could be lowered. An alignment device


60


(not shown in

FIG. 2

) can be used to guide the selected article


36


from the shelf


20


onto the conveyor and then to hold the article during vertical transport of the elevator


30


. This alignment device


60


can then be retracted in order to permit horizontal transport of the article


36


in the direction of arrow


40


. This operation can occur after lowering of the elevator such that the article will be dispensed directed to the vend port


16


. Of course, if this vend port


16


is located in some other position, different movement of the elevator


30


and conveyor


32


are possible. For example, if the vend port


16


were on the left-hand side of the vending machine, then the positioning of the drive


34


could be switched and the conveyor could operate in a direction opposite to that of arrow


40


. Also, the article


36


could first be moved in the direction of arrow


40


and then the elevator could be lowered or these operations could occur simultaneously.




The alignment device


60


will now be described with reference to FIG.


5


. In

FIG. 5

, an exploded view of the alignment device


60


is shown. The belt


62


of conveyor


32


extends over the elevator bottom frame


64


. The drive


34


and end rollers


44


,


46


for the conveyor are mounted on this elevator frame


64


. In the embodiment of

FIG. 5

, the conveyor drive


34


′ is mounted differently from the previously described conveyor drive


34


. In particular, the belt


68


connects the motor


34


′ and roller


44


. A vertical roller


66


is provided for guiding this belt


68


. The drive


34


′ and belt


68


can be positioned within the elevator frame


64


in an out-of-the-way position. The previously described control wire


56


can operatively be connected to this conveyor drive


34


′.




This alternative mounting for the conveyor drive


34


′ merely illustrates some different variations possible with the vending machine


10


of the present invention. The elevator drive


34


could also be attached to either end of the elevator frame


64


as noted above.




Within the elevator frame


64


, a tension roller


70


is provided. This roller


70


aids in maintaining the belt


62


taunt. The conveyor


32


is moveable relative to the elevator frame


64


.




One of the elevator cables


52


is shown in FIG.


5


. This cable is attached to the elevator frame


64


by clamp


72


. It should be appreciated that the other corners of the frame


64


could also be connected to the cables


52


other arrangements for mounting of the cables


52


are possible as has been described above.




The alignment device


60


includes a panel


74


mounted to the elevator frame


64


. This panel


74


in

FIG. 5

is transparent. However, only a partially transparent or totally opaque panel


74


could be provided, if so desired.




A plurality of support members


76


are provided on the inner face of the panel


74


. The opposite side of the panel


74


faces the transparent window


12


of the vending machine


10


.




An upper bar


78


and a lower bar


80


are pivotally mounted to the panel


74


. Brackets


82


engage the support member


76


in order to pivotally hold the upper and lower bars


78


,


80


. Each of the bars


78


,


80


have outwardly extending tines


84


. In

FIG. 5

, the upper bar


78


is shown with V-shaped tines, while the lower bar has straight linear tines


84


. In

FIG. 5

, the tines define a plurality of slots


86


therebetween. While nine slots are shown in

FIG. 5

, it is contemplated that any number of slots could be provided. Each row of articles on shelves


20


should have an associated slot


86


. Therefore, when the elevator


30


reaches the desired position, the selected item


36


can move from the shelf


20


onto the conveyor


32


. This selected article will be received in one of the slots


86


which corresponds to the shelf from which it was dispensed.




Because the illustrated selected article


36


is a beverage bottle with the upper diameter being smaller than its lower diameter, the V-shaped upper tines


84


help accommodate this change in container shape. Of course, if cylindrical or square items, for example, were being dispensed, then the upper tines


84


could be straight tines similar to the tines


84


on lower bar


80


. Any arrangement for the tines


84


is possible.




Both the upper and lower bars


78


,


80


are connected to rod


88


. The connection


90


for the rod


88


to the bars


78


,


80


additionally has a return spring


92


. This spring


92


will urge the rod


88


in a downward direction in order to maintain the bars


78


,


80


in the position as shown in FIG.


5


.




The elevator frame


64


has a solenoid


94


and bell-crank


96


connected thereto. The solenoid


94


is extendable and retractable in order to move the bell-crank


96


to raise and lower the rod


88


. Upon activation of the solenoid


94


, the rod


88


is moved in order to pivot the bars


78


,


80


to raise or lower the tines


84


.




It is contemplated that when a selected article


36


is dispensed to one of the slots


86


, the tines


84


will help hold this article in its upright position. The elevator


30


then can be moved to the height of the vend port


16


. Thereafter, the solenoid


94


can raise the rod


88


and therefore, pivot the tines


84


to an out-of-the-way position. The belt


62


of conveyor


32


is then moved by drive


34


or


34


′ in order to horizontally transport the selected article


36


. Of course, the conveyor


32


could first be activated and then the elevator


30


could be raised or lowered. Moreover, if articles that did not tend to tip over were being handled, then the alignment device


60


could be omitted if so desired. Of course, vending machine


10


could dispense a combination of items, some of which require use of alignment device


60


while others do not.




The brackets


82


and the support members


76


allow the bars


78


,


80


to pivot on the panel


74


. A bumper


98


is provided on panel


74


in order to cushion engagement between the selected article


36


and the panel


74


. This bumper


98


could be omitted if so desired.




Because the panel


74


is transparent, the dispensing operation of the selected article


36


is not obstructed. Operation of the rods


78


,


80


and the conveyor


32


is visible by a consumer, therefore increasing interest in the vended product. Of course, this panel


74


does not need to be completely transparent or could instead be opaque, if so desired.




Along the bottom edge


100


of panel


74


, a place for indicia


102


can be provided. Such indicia


102


is shown in FIG.


2


. The end rollers


44


,


46


are not visible through bottom edge


100


due to the frame


64


, but could be visible if so desired, for example as shown in FIG.


2


. The panel


74


is mounted to the elevator bottom frame


64


and is therefore vertically moveable therewith. The panel


74


is between the conveyor


32


and the face of the vending machine


10


. When dispensing a selected article


36


, it will first move from shelf


20


towards the window


12


in the vending machine


10


. Then the conveyor


32


will move the article in the direction perpendicular to the front face of the vending machine. While it is contemplated that flat shelves


20


will be used, it is possible that a conveyor arrangement can also be used on the shelves. For example, a power conveyor for each row of articles or roller conveyors could be used if so desired.




In

FIGS. 1

,


2


, and


3


, different vending machine face arrangements are shown. All of these arrangements have selection buttons


104


. In

FIG. 1

, the vend port


16


is open whereas in

FIG. 2

, a slidable cover


106


is provided. A bill validator


108


, coin slot


110


, and coin return


112


are provided in the face of the vending machine of FIG.


3


. The coin slot


110


and coin return


112


are used in conjunction with coin mechanism


118


. Of course, any of the vending machines can have any combination of these conventional features. In addition, a video display, such as


114


in

FIG. 3

, could be provided in any of the vending machines. Of course, instead of a video display


114


, a conventional light box with an associated graphics panel could be utilized.




In

FIGS. 3 and 4

, the A.C. distribution box


116


is mounted in the vending machine housing


22


and is schematically shown. The dotted-line section


120


in

FIG. 4

represents an interior wall of the vending machine. Other conventional components for a vending machine can be provided in the machine


10


of the present invention.




In operation, a consumer can insert a bill into the bill validator


108


or coins into the coin slot


110


. The consumer will then choose an item through selection buttons


104


. The subsequent dispensing operation can be viewed through the transparent window


12


. The elevator


30


will move to the desired height if not already in position. The selected article


36


will move from the shelf


20


onto the conveyor


32


. A suitable ramp or lip can be provided on either the shelf


20


or elevator


30


in order to aid in the transit of the article


36


from the shelf to the elevator


30


as noted above.




If the alignment device


60


is provided, it will aid in maintaining the article


36


in the upright position during vertical transport. This alignment device


60


can then be lifted and the article horizontally conveyed. Alternatively, the alignment device


60


can be moved to an out-of-the-way position and horizontal transport can first occur before vertical transfer occurs or these operations can take place simultaneously. Depending on the item being dispensed, different operations of the vending machine


10


are possible. Moreover, as has been noted above, the alignment device


60


can totally be omitted if so desired.




Nonetheless, to discuss one possible vending operation, the selected article


36


is moved onto conveyor


32


. The alignment device


60


will hold it in position while the elevator


30


is lowered or raised to the height of the vend port


16


. The solenoid


94


will then pivot the bars,


78


,


80


in order to raise tines


84


. Thereafter, the conveyor


32


can be activated in order to move the selected article


36


to the vend port


16


. The consumer can view this entire operation in order to thereby increase interest in the vending operation. With increased interest, increased sales should result.




During this raising and lowering of the elevator


30


, it is linearly moved adjacent to the transparent window


12


. The bottom member frame


64


of the elevator


30


extends in a longitudinal direction that is generally parallel to the transparent window


12


. Basically, the elevator


30


moves in a first direction while the conveyor


32


moves in a second, perpendicular direction.




Turning now to the embodiment of

FIG. 6

, a modified form of the elevator


30


′ is shown. Instead of using the above-described conveyor


32


on the elevator, a simpler design is utilized. In particular, a tiltable elevator bed


122


is provided on the frame


64


of vertically movable elevator


30


′. This type of slide and dump elevator


30


′ as will be described hereinbelow can be used with the vending machine described in the above-identified U.S. patent application Ser. No. 09/045,005. In fact the previously described elevator


30


with conveyor


32


could be used in the vending machine of U.S. patent application Ser. No. 09/045,005.




In the modified form of the elevator


30


′, the elevator bed


122


is pivotable about point


124


. An actuation device


126


is provided on the wall of elevator shaft adjacent the path of the elevator


30


′. In the

FIG. 6

arrangement, the pivot point


124


is shown on the left-hand side of the elevator. As should be appreciated, the pivot point


124


could instead be on the right-hand side of the elevator shaft with the actuation means device


126


being on the left-hand wall. Other arrangements for the activation device


126


will become apparent in view of the description to follow.




A selected article


36


is provided on the elevator bed


122


in FIG.


6


. This article has simply been dispensed from the shelves


20


of the vending machine


10


. In

FIG. 3

, a single tilt rail


128


is shown at the end of one of the dividers


48


. It should be appreciated that each divider


48


could have such a downwardly and leftward slopping tilt rail


128


(as shown in FIG.


3


). These


128


rails work such that upon dispensing of a selected article


36


from a row on shelf


20


, the top of the article will be laid down onto the elevator bed


122


. The ends of the tilt rails


128


do not extend into the path of the elevator


30


′ such that they will not interfere with moving of the elevator


30


′. Because the right and left dividers


48


for each rail would have such a rail


128


, the article can be securely guided into its tilted position. As noted above, only a single tilt rail


128


is shown in

FIG. 3

for simplicity. However, each of the dividers


48


could have such a rail. Moreover, instead of being a separate element from the rail, the ends of the dividers


48


themselves could be bent such that their full length or only a partial height thereof would be utilized in tilting the articles from the vertical to a horizontal orientation.




Due to the downward and leftward slope of the tilt rail


128


shown in

FIG. 3

, the top of the selected article


36


would face the right-hand portion of the vending machine. In

FIG. 6

, an opposite arrangement is shown. This arrangement of

FIG. 6

is contemplated as having a discharge port


16


adjacent the left-hand portion of the elevator shaft. However, in the

FIG. 3

embodiment, the discharge port would be adjacent the right-hand portion of the elevator shaft such that the selected article


36


would be tilted to have its bottom


130


facing the vend port


16


. As will be explained, this orientation can result in dispensing of an upstanding article or at least dispensing of an article having its top above its bottom


130


. Therefore, it should be appreciated in the

FIG. 6

arrangement that if the vend port where actually on the right-hand side of the shaft, then the pivot point


124


for the elevator bed


122


would be located on the right-hand side of the elevator


30


′. Also, the tilt rails


128


would tilt the articles such that the bottom


130


would face the right-hand side of the elevator


30


′. If elongated articles such as beverage cans or bottles are not dispensed, but instead articles with relatively low centers of gravity were dispensed, then the tilting of the article by the tilt rails could be omitted. The article would just simply slide from one of the rows on shelves


20


onto to the elevator


122


and then slide on the elevator bed


122


to a chute


132


. Thus, the elevator bed


122


acts as a conveyor or slide.




In

FIG. 6

, the fixed chute


132


will now be described. This chute


132


is provided adjacent the elevator path and leads to the vend port


16


. Anti-pilfer devices can be provided between the vend port


16


and this chute


132


, if so desired.




The actuation device


126


is mounted on the wall of the shaft area of the vending machine opposite chute


132


. This actuation device


126


includes solenoid


134


operatively connected to actuation lever


136


. This lever


136


is pivotable about point


138


.




Upon actuation of solenoid


134


, the lever


136


will move from its inoperative position shown in

FIG. 6

to the operative position shown in FIG.


7


. In this actuated position, the lever


136


extends into the path of the elevator


30


′. A catch


140


is provided at the end of elevator bed


122


. This catch


140


will be engaged by the actuation lever


136


in order to lift the elevator bed


122


to a raised position as shown in FIG.


8


. The actuation device


126


is fixed on the wall of the vending machine or to the shaft. Lifting of the bed


122


occurs after engagement with lever


136


and continued downward movement of the elevator


30


′ as will be described below. In the

FIG. 8

position, the selected article


36


will slide from the elevator bed


122


onto chute


132


. From the chute


132


, the article will be available at the vend port


16


of vending machine


10


.




The catch


140


is better shown in

FIGS. 9 and 10

. This catch


140


is spring loaded by spring


142


to normally be in its retracted position as shown in FIG.


9


. However, when engaged by the actuated lever


136


, the catch


140


will be moved to the extended position as shown in

FIG. 10

thereby compressing spring


142


. Of course, this spring arrangement could be modified to instead use a tension spring. Extension of the lever


142


and subsequent tilting of the bed


122


is carried out by the elevator


30


′ moving in a downward direction. In particular, when the lever


136


is actuated to move into the path of the elevator, the catch


140


will be engaged by this lever


136


as the elevator


30


′ moves downwardly. Continued downward movement of the elevator


30


′ causes the catch


140


to extend and causes compression of spring


142


. This downward movement will also cause the elevator bed


122


to pivot about point


124


. As noted above, this action will cause the selected article


136


to slide from the elevator bed


122


onto chute


132


.




It is contemplated that the elevator bed


122


can simply be a flat surface but a groove or V-shape could be used to center the article


36


. For example, a metal sheet or wooden platform can be used. Of course, this elevator bed


122


can be coated with material in order to aid sliding of the article


36


. In fact, rollers or other non-powered conveyor means could be used on the tiltable elevator bed


122


. In addition, a powered conveyor arrangement similar to the first embodiment could be used on this elevator bed


122


if so desired.




The modified elevator


30


′ of

FIGS. 6-8

has an advantage over the powered conveyor


32


used on the elevator


30


of the first embodiment. In particular, this elevator


30


′ with tiltable elevator bed


122


is less expensive to manufacture and maintain.




It should be noted that when the actuation device


126


is in the neutral or non-activated position of

FIG. 6

, the elevator


30


′ is free to travel along the elevator path. The catch


140


will not interact with this actuation device


126


until it moves to the position of FIG.


7


. The location of the actuation device


126


and chute


132


could be varied such that the vend port


16


would be located at any suitable height of the vending machine. For example, if the vend port


16


were near the top of the vending machine, it would be possible for the elevator


30


′ to move downwardly passed the unactuated device


126


. The elevator would then receive the selected article


136


from a shelf


20


and move upwardly passed the actuation device


126


. After the elevator has reached this position, it would then return to a downward movement after or during pivoting of the lever


136


to the

FIG. 7

position. Continued downward movement of the elevator


30


′ would cause the catch


140


to be engaged with the lever


136


for subsequent dispensing of the article


36


to chute


132


. Of course, if the vend port


16


were located towards the bottom of the vending machine, it may be necessary to have the elevator


30


′ first receive a product and then move upwardly to a position above the actuation device


126


. Rather, the elevator


30


′ could move to a suitable location to receive an article from one of the shelves


20


. Then the elevator would simply move downwardly in order to engage the actuated lever


136


for subsequent discharge of article


36


to chute


132


. Either way, it is possible to have many different designs for the location of vend port


16


.




After the selected article


36


has been dispensed to chute


132


, the elevator


30


′ can move upwardly from its position in FIG.


8


. This will disengage the catch


140


from the actuation device


126


. The solenoid


134


can return the actuation lever


136


to its inoperative position of FIG.


6


. Alternatively, rather than using a powered solenoid arrangement, a return spring or other arrangement could be used for pivoting this lever


136


back to its inoperative position. As the elevator


30


′ moves upwardly to disengage the catch


140


from the lever


136


, the bed


122


will pivot in a clockwise direction about point


124


in order to return to its horizontal orientation. When the catch


140


and lever


136


are disengaged from one another, the spring


142


will return the catch


140


to its retracted position as shown in FIG.


9


. Of course, rather than using a spring


142


, other arrangements are possible for returning this catch


140


to its inoperative position.




Until the actuation device


126


is again turned on to move lever


136


into the path of movement of the elevator


30


′, the elevator


30


′ is free to move upwardly and downwardly passed this actuation device


126


without subsequent tilting of the elevator bed


122


. However, when it is desired to dispense an article, then the actuation device


126


can again be activated




Another exemplary embodiment of the vending machine of the present invention is shown in

FIGS. 11-16

. As embodied herein and referring to

FIGS. 3

,


11


,


12


, and


14


, the vending machine


10


includes a shelf


220


and a conveyor


232


. The conveyor


232


may include an endless belt mounted around two opposed rollers, similar to that described above. The shelf


220


supports one or more articles


212


that may be selectively vended from the machine


10


. The articles


212


may be, for example, bottles, cans, boxes, or pouches containing a beverage. The shelf


220


supports the articles


212


in an upright orientation, such that the bottom


214


of an article rests on the shelf


220


and the top


216


of the article extends away from the shelf


220


.




The articles


212


are typically aligned in one or more rows


218


extending from the front end


222


of the shelf to the rear end


224


of the shelf, the front of the shelf being the end nearest the conveyor


232


The rows of articles may be separated by dividers


248


to help maintain the alignment of the articles. For purposes of clarity,

FIGS. 11 and 12

illustrate only one of the rows of articles on the shelf. The features shown in

FIGS. 11 and 12

could be implemented in each row, if desired, and with the modifications described below for the left-most and right-most rows


226


,


228


.




The articles may be delivered from the shelf


220


to the conveyor


232


by any known method, as described above. For example, in one embodiment, the shelf


220


slopes downward at an angle of approximately 10° from the rear end


224


to the front end


222


to effect a gravity feed of the articles from the shelf


220


toward the conveyor


232


. In addition or alternatively, a gating system (not shown) may be employed with or without a spring-biased pusher to deliver articles from the shelf


220


to the conveyor


232


.




The vending machine


10


also includes a tipping mechanism


250


for a row


219


of articles. As illustrated in

FIGS. 11 and 12

, the tipping mechanism


250


includes a ramp


252


that extends from the front


222


of the shelf to the rear


224


of the shelf and a spacer


254


between the shelf


220


and the ramp


252


. The spacer


254


is positioned at the front end


222


of the shelf and toward the right side of the row


219


. At the rear end


224


of the shelf, the ramp


252


rests generally flat on the shelf


220


; while at the front end


222


of the shelf, the ramp


252


angles upward from the shelf


220


, with the right side of the ramp supported by the spacer


254


. Thus, the ramp slopes gently upward from the rear end


224


of the shelf to the front


222


and from the left side of the row


219


to the right. As a result, the tops


216


of the articles nearer to the front end


222


of the shelf tip toward the left, and the articles supported at the rear


224


of the shelf are oriented more upright that those supported toward the front.




The tipping mechanism


250


may also include a product rotator


256


extending from the shelf


220


. The product rotator


256


is positioned toward the right side of the row


219


of articles. A top surface


258


of the product rotator


256


is substantially aligned with a top surface


221


of the shelf


220


. In an embodiment where the shelf


220


slopes downward from the rear


224


to the front


222


, the product rotator


256


is positioned at a vertical height below that of the ramp


252


, but the top surface


258


of the product rotator


256


is aligned with the top surface


253


of the ramp


252


, as illustrated in FIG.


11


. The product rotator


256


maintains or increases the tipped orientation of an article being delivered from the shelf


220


to the conveyor


232


. The product rotator


256


may extend from the shelf


220


to any point that does not interfere with the operation of the conveyor


232


. The product rotator


256


may, for example, be an L-shaped flange, as shown in FIG.


13


. The rounded corner of the flange shown in

FIG. 13

assists with tipping the article.




In operation, the shelf supports one or more rows


218


of articles


212


. The articles toward the front


222


of the shelf are tilted toward the left as a result of the tipping mechanism


250


. In particular, the spacer


254


causes a front corner of the ramp


252


to be elevated from the shelf


220


. An article is selectively delivered from the shelf


220


to the conveyor


232


in accordance with a selection request input by a consumer.




As the article exits the shelf


220


, the right portion of the bottom


214


of the article contacts the product rotator


256


, causing the article to tip further toward the left. The article continues tipping until is reaches the conveyor


232


. Eventually, the article attains a lateral orientation substantially perpendicular to the original, upright orientation.




In a preferred embodiment, the conveyor


232


is driven substantially simultaneously with the delivery of the article from the shelf


220


to the conveyor


232


. The conveyor


232


is driven in a direction opposite to the tipping direction of the article. For example, as the top


216


of the article tips toward the left, the conveyor


232


is driven from left to right. As the bottom


214


of the tipping article comes in contact with the conveyor


232


, the conveyor


232


contributes to the tipping motion of the article, thereby assisting the article to attain the lateral orientation.




With the article in the lateral orientation and the bottom


214


of the article facing in a direction of the vend port


16


, the conveyor


232


transports the article horizontally toward the vend port


16


. As the bottom


214


of the article over the roller nearest to the vend port


16


, the bottom


214


begins to tip downward and the top


216


begins to tip upward until the article attains the substantially upright orientation and arrives at the vend port


16


.




It should be appreciated that in order to facilitate the re-orientation of the article to the substantially upright orientation and delivery of the substantially upright article to the vend port


16


, the conveyor


232


must be positioned at a horizontal level at least toward the top of the vend port


16


. Also, the region of the vending machine between the conveyor


232


and the vend port is configured so as not to impede the reorientation of the article to the substantially upright position.




As can be seen from

FIG. 3

, the left-most and right-most rows


226


,


228


of articles are positioned proximal to the left- and right-side walls


206


,


208


of the vending compartment. These side walls


206


,


208


may affect the operation of the invention, described above, for the left- and right-most rows


226


,


228


of articles. Thus, the tipping mechanisms for these rows are modified so that the articles can be tipped as they are delivered from the shelf


220


to the conveyor


232


, without interference from the side walls


206


,


208


, and eventually attain a lateral orientation.




As shown in

FIGS. 14 and 15

, the left end


234


of the conveyor


232


includes a slide


260


. The slide


260


is positioned on the conveyor


232


to align toward the left side of the left-most row


226


of articles, while not impeding progress of an article from the shelf


220


to the conveyor


232


. As the article is delivered from the shelf


220


to the conveyor


232


, the slide


260


assists the bottom


214


of the article in moving toward the right, thus allowing the top


216


of the article to continue tipping toward the left. Also, the left-most row does not includes a product rotator, since the product rotator would hinder the rightward movement of the bottom


214


of the article as it is delivered from the shelf


220


to the conveyor


232


.




Also illustrated in

FIG. 14

, the right end


236


of the conveyor includes a tip arm


262


. The tip arm


262


is positioned on the conveyor


232


to align toward the right side of the right-most row


228


of articles while not impeding progress of an article from the shelf


220


to the conveyor


232


. As the article is delivered from the shelf


220


to the conveyor


232


, the tip arm


262


contacts an upper portion of the article, causing the top


216


of the article to continue tipping toward the left. As shown in

FIGS. 15 and 16

, the tip arm


262


may include an angled flag portion


264


for contacting the article and a jogged post


266


to provide clearance for the article delivered to the conveyor


232


.




In one embodiment, the vending machine includes a plurality of shelves, each shelf having a plurality of rows of articles to be vended. In this embodiment, the conveyor is mounted on an elevator, similar to that described above. The elevator moves the conveyor, and any article on the conveyor, in a vertical direction between the shelves and the discharge port. Preferably, the conveyor is not driven while the elevator moves vertically. Alternatively, a conveyor carrying an article could be driven while the elevator moves as long as a sensor or other mechanism is employed to ensure that the article does not prematurely leave the conveyor.




It should be appreciated that a tiltable elevator, similar to that described above with respect to

FIGS. 6-10

, may also be employed to deliver a laterally-oriented article to the discharge port. In this situation, the elevator may or may not include the conveyor


232


for assisting with the tipping of articles from the substantially upright orientation to the lateral orientation.




It should also be appreciated the vending machine may include the vend port on a left-hand side, i.e., opposite that shown in

FIGS. 1-3

. As a result, the features and operation as described with respect to

FIGS. 11-14

would simply need to be reversed. For example, the spacer and product rotator would be positioned toward the left side of the row, the slide would be on the right end of the conveyor and the tip arm would be on the left, and the tops of the articles would tip toward the right as they approach the front end of the shelf


220


and are delivered to the conveyor.




Yet further, it should be appreciated that the shelf


220


may include a corrugated, finned, or knurled surface in order to reduce the surface area of the shelf in contact with the bottom


214


of an article.




Anti-pilfer devices can be provided in the area of the vend port


16


of all embodiments. Such anti-pilfer devices are conventional in the art. Morecver, the vending machine of the present invention is readily portable.




Accordingly, the present invention provides a vending machine


10


that can increase consumer's interest in the vended products and therefore, increase sales. Great flexibility is had with the vending machine


10


due to the provision of the elevator


30


and conveyor


32


or tiltable elevator bed


122


. The vend port


16


can be located in many different locations thereby varying the look and operation of the vending machine


10


. When using the conveyor


32


arrangement along with the alignment device


60


, if so desired, the vending machine can aid in maintaining dispensed products in a desired vertical orientation. Therefore, elongated articles can be maintained in their upright position during dispensing.
