TECHNICAL FIELD
The present application relates generally to vending machines and mechanisms and more particularly relates to simplified vending mechanisms positioned within a cooler.
BACKGROUND OF THE INVENTION
Traditional vending machines generally are intended to be positioned in locations of moderate to heavy consumer traffic. Locations with less consumer traffic, such as certain offices, hospitals, schools, retail establishments, and the like, may not be well suited for the usual size and expense related to the use of a traditional vending machine. Specifically, the components of the vending machine, such as the vending mechanism, the refrigeration equipment, the payment equipment, the product stocks, and the like, may be relatively expensive to provide and operate. Moreover, the size of the traditional vending machine may result in a slow rotation of product through the vending machine.
Coolers, particularly glass door coolers, may be somewhat less expensive to provide and operate given the lack of at least the vending mechanism. Glass door coolers also generally offer the advantage of allowing the consumer to see the products available within the cooler. Such visibility may provide the opportunity to promote the products therein and also may promote impulse purchases. The lack of the vending mechanism, however, generally means that the removal of products from the cooler cannot always be controlled.
There is thus a desire therefore for an improved vending machine. Such a vending machine may offer the positive features of a glass door cooler but with appropriate vending controls. Further, such an improved vending machine should be less expensive to provide and operate as compared to a traditional vending machine and the like.
SUMMARY OF THE INVENTION
The present application thus provides a product vending module for vending a number of products. The product vending module includes a product row configured to contain a number of products therein. The product vending module also includes a product gate positioned about the product row and rotatable from a closed position preventing access to the number of products to an open position allowing access to one of the number of products while preventing access to a remainder of the number of products, the product gate including a biased base. The product vending module further includes a product locking system in communication with the product gate, the product locking system including a locking pin releasably engaging the biased base and movable from a first position allowing rotation of the product gate toward the closed position to a second position restricting rotation of the product gate toward the closed position.
The present application further provides a method of vending a number of products. The method includes the steps of providing a product vending module containing a number of products therein, allowing a product gate of the product vending module to rotate from a closed position preventing access to the number of products to an open position allowing access to one of the number of products while preventing access to a remainder of the number of products, moving a locking pin from a first position to a second position to maintain the product gate in the open position, and moving the locking pin from the second position to the first position to allow rotation of the product gate toward the closed position.
The present application further provides a vendor for vending a number of products. The vendor includes a number of product vending modules. Each of the product vending modules includes a product row configured to contain a number of products therein, and a product gate positioned about the product row and rotatable from a closed position preventing access to the number of products to an open position allowing access to one of the number of products while preventing access to a remainder of the number of products, the product gate including a biased base. Each of the product vending modules also includes a product locking system in communication with the product gate. The product locking system includes a latch releasably engaging the biased base and movable from a first position restricting rotation of the product gate toward the open position to a second position allowing rotation of the product gate toward the open position. The product locking system also includes a locking pin releasably engaging the biased base and movable from a first position allowing rotation of the product gate toward the closed position to a second position restricting rotation of the product gate toward the closed position.
These and other features and improvements of the present application will become apparent to one of ordinary skill in the art upon review of the following detailed description when taken in conjunction with the several drawings and the appended claims.

DETAILED DESCRIPTION
The present application concerns the vending of any number of products 10. Although the products 10 are shown, by way of example only, in the form of cans 20, it is understood that the products 10 may include any type or size of container including, but not limited to, cans, bottles, pouches, boxes, wrapped items, and/or any type of rigid or flexible packaging. The products 10 may include beverages, food items, non-food items, consumer products, and/or any type of product 10 that may be vended. The scope of the application is in no way limited by the nature of the products 10 intended to be vended herein or otherwise. Similarly, while one use herein is for a chilled product 10, it will be understood that the products 10 herein may be at ambient temperatures, elevated temperatures, or at any temperature.
Referring now to the drawings, in which like numerals refer to like elements throughout the several views, FIG. 1 shows a vendor 100 as may be described herein. The individual components of the vendor 100 described in detail below may be generally modular in nature. As such, the various components may be original equipment and/or retrofitted as desired. Likewise, not all of the components may be required to operate the vendor 100 as a whole. Rather, many alternative configurations may be used herein. The vendor 100 may be primarily intended for indoor use but may be located anywhere adjacent to an electrical power source and the like.
The vendor 100 may include a cooler 110. As is shown in FIG. 2, the cooler 110 may include an outer frame 120 enclosed by a door 130. The frame 120 and the door 130 may be largely of conventional design and may be insulated as desired. The door 130 may include a transparent panel 140 therein. The transparent panel 140 may be made out of glass and the like. The door 130 may swing open and may include a lock or other type of anti-tamper mechanisms thereon. The cooler 110 may have any desired size or shape.
The vendor 100 also may include a refrigeration/heating cassette 150 positioned within the cooler 110. Specifically, the refrigeration/heating cassette 150 may be positioned within a refrigeration/heating compartment 160 of the frame 120 or otherwise. The refrigeration/heating cassette 150 may be modular and may be of conventional design. An example of the refrigeration/heating cassette 150 is shown in commonly owned U.S. Pat. No. 7,117,689, entitled “Removable Refrigeration Cassette for a Hot and Cold Vending Machine” to Rudick, et al. U.S. Pat. No. 7,117,689 is incorporated herein by reference in full. Other types of heating and/or refrigeration devices may be used herein. Refrigeration, heating, and/or both thus may be provided herein.
The vendor 100 also may include a payment device 170. The components of the payment device 170 may be positioned about the frame 120 and the door 130 of the cooler 110. Specifically as is shown in FIG. 3, the door 130 may include a money slot 180, a money return button 190, and a money return holder 200. A status display panel 210 also may be positioned on the door 130. These and other components of the payment device 170 positioned on the door 130 in turn may cooperate with the components positioned within the frame 120.
As shown in FIG. 4, these components may include a money channel 220 in communication with the money slot 180 and a money return channel 230 in communication with the money return holder 200. Also positioned about the frame 120 may be a payment system 240, a money return unit 250, and a money box 260. The components of the payment device 170 may be controlled by an electronic control 270. The electronic control 270 may be a conventional programmable microprocessor and the like. The electronic control 270 also may communicate with other components of the overall vendor 100 as will be described in more detail below. The payment device 170 also may include other or different components and other or different configurations.
The vendor 100 further may include a vending device 300. The vending device 300 may be positioned within a vending compartment 310 of the cooler 100. The vending device 300 and the vending compartment 310 may be in communication with the refrigeration/heating cassette 150 positioned within the refrigeration/heating compartment 160. The vending device 300 may have any size or shape. Other configurations may be used herein.
As is shown in FIGS. 1 and 5, the vending device 300 may include a number of product shelves 320. The product shelves 320 may be positioned on a pair of fixed guides 330 or otherwise. The product shelves 320 may be slidable within the fixed guide 330 so as to provide for easy first in, first out loading for the products 10 and also to remove the product shelves 320 themselves. One or more of the product shelves 320 may be positioned at an angle from back to front so as to promote self feeding of the products 10 therein via gravity. Other types of shelf configurations also may be used herein.
FIG. 6 shows one of the product shelves 320. Each product shelf 320 may have a number of lateral walls 340 that define a number of product rows 350. Any number of product rows 350 may be used. Likewise, the product rows 350 may have any dimension. Different sizes and shapes of product rows 350 also may be used together. As is shown, a number of the products 10 may be positioned within each of the product row 350.
The lower end of each product row 350 may include a product gate system 360. The product gate system 360 ensures that only one product 10 is removed from the product shelf 320 during each vend. Each of the product gate systems 360 includes a product gate 370. The product gate 370 preferably may be made from a transparent material such that the products 10 therein may be visible in whole or in part. The product gate 370 may have a somewhat convex shape and may extend for about the length of the product 10 intended to be positioned therein. Other shapes and sizes may be used herein. Each product gate 370 includes a largely vertically extending door 380 positioned on a pivoting base 390. The pivoting base 390 may be attached to the end of the product row 350. Although the base 390 is shown as largely circular in shape, any size or shape may be used herein.
As is shown in FIGS. 7 and 8, the product gate system 360 also may include a number of levers, a first lever 400 and a second lever 410. The first lever 400 may be attached to the base 390 and pivots therewith so as to pull the second lever 410 along as the base 390 rotates. The second lever 410 in turn pulls a flap 420. The second flap 420 serves to block the following product 10 once the first product in the product row 350 is removed from the base 390. Specifically, the levers 400, 410 rotate the flap 420 into contact with the next product 10 once the product gate 370 is rotated open. The terms “lever” and “flap” simply refer to any type of extended member and may have any size of shape. Other configurations may be used herein.
FIGS. 9 and 10 show a further embodiment of a product gate system 430. The system 430 also uses the first lever 400, the second lever 410, and the flap 420. This system 430 also uses a third lever 440 attached to a second flap 450. One end of the third lever 440 rides along a circular rib 460 positioned on the base 390. Rotation of the base 390 pivots the third lever 440 and the accompanying second flap 450 so as to provide a further barrier to the next product 10 in the row 350. Other configurations may be used herein.
As is shown in FIG. 11, the vending device 300 of the vendor 100 also may include a product shelf locking system 500 associated with the product gate systems 360. The product shelf locking system 500 prevents the remaining product gates 370 on a given product shelf 320 from opening once any one product gate 370 on the product shelf 320 is opened.
The product shelf locking system 500 may include a number of cams 510. The cams 510 may be attached to the base 390 of each product gate system 360 for rotation therewith. The product shelf locking system 500 also may include a number of cursors 520 or other type of movable position marker positioned about each set of cams 510. The cams 510 and the cursors 520 may have any desired size or shape. A cam spring 530 also may be attached to each cam 510 to return the cam 510 to its original position. The product shelf locking system 500 also may include an end cursor 540 positioned on one end thereof and having a cursor spring 550 attached to the adjacent cam 510. Rotation of any one of the product gates 570 also causes the related cam 510 to rotate as is shown in FIG. 12. This rotation pushes the remaining cursors 520 to the right such that their related cams 510 are blocked from rotation. This blocking thus prevents the remaining product gates 370 from rotating. As such, once one product gate 370 on a given product shelf 320 is rotated, then the remaining product gates 370 are locked. Other configurations may be used herein.
FIGS. 13-16 show an alternative embodiment of a product gate system 600. The product gate system 600 includes any number of product vending modules 610 with two such modules 612, 614 shown herein for purposes of example only. Each product vending module 610 may include an angled product row 620. Each angled product row 620 may be defined by a shelf floor 630 and one or more lateral walls 640. A number of the products 10 may be positioned within the angled product row 620 for gravity feeding therein. The angled product rows 620 may have any angle sufficient for gravity feeding. A number of product vending modules 610 may share a common shelf floor 630 and the lateral walls 640.
The product vending module 610 may include a vending frame 650. The vending frame 650 may be positioned about an end of the angled product row 620. The vending frame 650 may define a product area 660 for one of the products 10. The vending frame 650 may be enclosed by a product gate 670. The product gate 670 preferable may be made from a transparent material such that the products 10 therein may be visible in whole or in part. The product gate 670 may have a somewhat convex shape and may extend for about the length of the product 10 intended to be positioned therein and/or the length of the vending frame 650. Other components and other configurations may be used herein.
Each product gate 670 may include a largely vertically extending door 680 positioned on a pivoting base 690. Although the base 690 is shown as largely circular in shape, any size or shape may be used herein. The product vending module 610 also includes a support base 700. The support base 700 supports the vending frame 650 and the door 680 and the base 690 of the product gate 670. Other components and other configurations may be used herein.
Referring now to FIGS. 17-20, the product vending module 610 also may include a product locking system 710. The product locking system 710 may be positioned within the support base 700 so as to cooperate with the door 680 and the base 690 of the product gate 670. The product locking system 710 may include a latch 720 positioned about the base 690. The latch 720 may include a number of cam arms 730. The cam arms 730 may cooperate with and travel along a number of cam tracks 740 extending from the base 690. The latch 720 may be operated by a solenoid 750 and may be biased into a desired position via a latch spring 760. The base 690 likewise may be biased into position via a base spring 770. Other components and other configurations may be used herein.
The product locking system 710 also may include a micro-switch 780. The micro-switch 800 may be positioned about the base 690 and may include a switch arm 790 that rides along the cam tracks 740 thereof so as to determine the position and rotation of the base 690. Other configurations and other components may be used herein. The micro-switch 780 may be in communication with the control 270. A damper 785 also may be used about the base 690.
In use, FIGS. 13, 15, and 17 show an example of the product vending module 610 in a closed and locked position. The base 690 and the door 680 of the product gate 670 are locked. Upon receipt of an appropriate amount of credit as is described in more detail below, the control 270 may “arm” the solenoid 750 adjacent to the latch 720. Once the micro-switch 780 detects a small amount of movement of the base 690 caused by the opening of the door 680, the solenoid 760 releases the latch 720 so as to allow the base 690 to rotate as is shown in FIG. 18. The control 270 also guarantees that no two solenoids 750 may be open at one time. As is shown in FIG. 19, further opening of the door 680 and rotation of the base 690 mechanically pushes the latch 720 back into positioned via the cam track 740 and the latch spring 760. The product 10 may now be removed from the product area 660 as is shown in FIG. 16. The curvature of the door 680 prevents access to the next product 10 on the angled product row 620.
FIG. 20 shows the door 680 of the product gate 670 returning to the closed and locked position. The base 690 and the door 680 may rotate back to the original position via the base spring 770. Further opening of the door 680 may be prevented by a number of ratchets 800 positioned on the cam tracks 740 that interact with the cam arms 730 of the latch 720. The next product 10 may move into the product area 660 under the force of gravity once the door 680 clears the angled product row 620.
FIG. 21 shows a vendor 810 with a number of the product vending modules 610 positioned therein. In this example, a selection button 820 may be positioned about each product shelf 320. When credit has been established equal to the selected price for that product shelf 320, the selection button 820 may flash so as to indicate that the products 10 therein are available. The lighted selection button 820 thus indicates that the consumer may select a product 10 from that particular product shelf 320. The solenoids 750 for each product vending module 610 thus may be armed when the appropriate credit is entered. Opening the door 680 of any of the product vending modules 610 triggers the solenoid 750 therein to open the latch 720 while disarming the remaining solenoids 750 such that no other door 680 may be opened. The vend may be considered complete as the door 680 is rotated to the open position. The product 10 then may be removed and the product gate 670 may rotate shut. The consumer must open the door 680 by a sufficient degree of rotation to remove the product 10 therein for the vend to be considered complete. Alternatively, each product vending module 610 also may have an individual selection button 830 such that each product vending module 610 may be set at different price. Other configurations and other components also may be used herein.
Each product vending module 610 may be removable for easy reloading. Alternatively, an entire shelf 320 of the product vending modules 610 also may be removable. The product vending module 610 may accommodate different row widths, different row heights, and different packaging sizes while using the same product locking system 710. The vendors 100 described herein thus provide a low cost but flexible vending machine for lower volume locations and the like. The visibility of a glass door cooler is provided with simplified vending mechanisms for appropriate control and safety.
FIGS. 22-29 show an alternative embodiment of a product locking system 910 as may be used in the product vending module 610. The product locking system 910 may be positioned within the support base 700 so as to cooperate with the product gate 670, particularly the base 690 of the product gate 670. The product locking system 910 may include a latch 912 positioned about the base 690. As described in more detail below, the latch 912 may releasably engage the base 690 and be movable, such as by rotation, from a first position to a second position. The first position may be an engaged position, and the second position may be a released position. When in the first position, the latch 912 may restrict rotation of the product gate 670 toward the open position. When in the second position, the latch 912 may allow rotation of the product gate 670 toward the open position.
As is shown, the latch 912 may include a number of latch arms configured to releasably engage and cooperate with one or more cam tracks 914 of the base 690. Specifically, the latch 912 may include a first latch arm 916 configured to engage the cam track 914 when the latch 912 is in the first position. When the latch 912 is in the first position, the first latch arm 916 and the cam tracks 914 may cooperate to restrict rotation of the product gate 670 toward the open position. The latch 912 also may include a second latch arm 918 configured to engage the cam tracks 914 when the latch 912 is in the second position. When the latch 912 is in the second position, the second latch arm 918 may allow rotation of the product gate 670 toward the open position. As described in more detail below, as the product gate 670 is rotated from the closed position toward the open position, the second latch arm 918 and the cam tracks 914 may cooperate to control movement, such as rotation, of the latch 912.
As is shown, the product locking system 910 also may include a locking pin 920 configured to releasably engage and cooperate with the base 690. Specifically, the locking pin 920 may releasably engage a flange portion 922 of the base 690 and be movable from a first position to a second position. The first position may be a released position, and the second position may be an engaged position. When in the first position, the locking pin 920 may allow rotation of the product gate 670 toward the closed position. When in the second position, the locking pin 920 may restrict rotation of the product gate 670 toward the closed position. As is shown, the locking pin 920 may be at least partially received within a mating aperture 924 defined in the second latch arm 918. The locking pin 920 may be biased to extend out of the aperture 924, such as by a compression spring or other elastic component positioned within the aperture 924. As described in more detail below, when the latch 912 is in the second position and the product gate 670 is rotated from the closed position toward the open position, the locking pin 920 may engage a ramp 926 of the flange portion 922 of the base 690.
The latch 912 may be biased toward a desired position via a latch spring 928. Specifically, when the latch 912 is in the first position, the latch spring 928 may bias the latch 912 to maintain the first position. When the latch 912 is in the second position, the latch spring 928 may bias the latch to maintain the second position. As is shown, the latch spring 928 may be formed as a leaf spring, although other spring configurations may be used. The latch 912 may be moved from the first position to the second position via a solenoid 930. The base 690, and thus the entire product gate 670, may be biased toward a desired position via a base spring 932. Specifically, the base spring 932 may bias the base 690, and thus the entire product gate 670, toward the closed position. As is shown, the base spring 932 may be formed as a torsion spring, although other spring configurations may be used.
The product locking system 910 also may include a micro-switch 934. The micro-switch 934 may be positioned about the base 690 and configured to detect rotation of the base 690 and thus the entire product gate 670. Specifically, the micro-switch 934 may include a switch arm 936 configured to engage and ride along the cam tracks 914 of the base 690 so as to detect the rotational position of the base 690 and thus the entire product gate 670. The micro-switch 934 may be in communication with the control 270 so as to communicate information relating to the rotational position of the base 690 and thus the entire product gate 670. Other configurations and other components may be used herein.
FIGS. 22-29 illustrate an example of operation of the product locking system 910 as a part of the product vending module 610. FIGS. 22 and 26 show the product locking system 910 in a locked configuration as may be assumed when the product gate 670 is in the closed position (FIGS. 13 and 15). As is shown, the latch 912 is in the first position, such that the first latch arm 916 and the cam tracks 914 engage one another and cooperate to restrict rotation of the product gate 670 toward the open position. The latch spring 928 biases the latch 912 to maintain the first position. Upon receipt of an appropriate amount of credit, the control 270 may “arm” the solenoid 930. Once the micro-switch 934 detects a small amount of movement of the base 690 caused by initially rotating the door 680, and thus the entire product gate 670, by an angle α1 toward the open position, the solenoid 930 activates and moves the latch 912 from the first position to the second position. The angle α1 may be within a range of about 1 degree to about 15 degrees. As is shown, the angle α1 may be about 5 degrees, although other suitable angles may be used. The control 270 guarantees that only one solenoid 930 of one product vending module 610 may be activated at a time.
FIGS. 23 and 27 show the latch 912 in the second position allowing further rotation of the product gate 670 toward the open position. As is shown, the second latch arm 918 and the cam tracks 914 engage one another, and the locking pin 920 is positioned adjacent the flange portion 922 of the base 690. The latch spring 928 biases the latch 912 to maintain the second position. As the product gate 670 is rotated beyond the angle α1, the second latch arm 918 and the cam tracks 914 continue to engage one another, and the profile of the cam tracks 914 forces the second latch arm 918 to move away from a rotational axis of the product gate 670. The movement of the second latch arm 918 opposes the biasing force of the latch spring 928, thereby increasing frictional forces generated between the second latch arm 918 and the cam tracks 914. The frictional forces generated between the second latch arm 918 and the cam tracks 914 may restrict rotation of the product gate 670 toward the closed position. Accordingly, when the latch 912 is in the second position, the latch 912 may restrict rotation of the product gate 670 toward the closed position.
Meanwhile, as the product gate 670 is rotated beyond the angle α1, the locking pin 920 engages the ramp 926 of the flange portion 922, which forces the locking pin 920 to retract into the aperture 924. The retraction of the locking pin 920 compresses the compression spring or other elastic component positioned within the aperture 924, thereby increasing frictional forces generated between the locking pin 920 and the flange portion 922. The frictional forces generated between the locking pin 920 and the flange portion 922 may restrict rotation of the product gate 670 toward the closed position. Accordingly, when the locking pin 920 is in the second position and engages the flange portion 922, the locking pin 920 may restrict rotation of the product gate 670 toward the closed position. When the locking pin 920 is in the second position and engages the flange portion 922, the locking pin 920 may maintain a rotational position of the product gate 670 in the event of removal of external forces on the product gate 670 (i.e., the product gate 670 is no longer being held or rotated by a user toward the open position). In other words, the frictional forces generated between the locking pin 920 and the flange portion 922 may be greater than opposing forces, such as the biasing force provided by the base spring 932, which tend to urge the product gate 670 toward the closed position.
FIG. 28 shows the latch 912 in the second position following further rotation, beyond the angle α1, of the product gate 670 toward the open position. As is shown, the second latch arm 918 and the cam tracks 914 continue to engage one another, while the locking pin 920 continues to engage the ramp 926 of the flange portion 922 and retract further into the aperture 924. In this manner, the locking pin 920 may continue to restrict rotation of the product gate 670 toward the closed position.
FIG. 24 shows the latch 912 in the second position following still further rotation of the product gate 670 to an angle α2 corresponding to the open position of the product gate 670 allowing access to one of the products 10 contained in the product row 620 while preventing access to a remainder of the products 10. The angle α2 may be within a range of about 55 degrees to about 90 degrees. As is shown, the angle α2 may be about 72.5 degrees, although other suitable angles may be used. As is shown, the second latch arm 918 and the cam tracks 914 continue to engage one another, while the locking pin 920 continues to engage the flange portion 922 and retract further into the aperture 924. In this manner, the locking pin 920 may continue to restrict rotation of the product gate 670 toward the closed position and may maintain the product gate in the open position. As the product gate 670 is rotated beyond the angle α2, the profile of the cam tracks 914 forces the second latch arm 918 to move further away from a rotational axis of the product gate 670. The movement of the second latch arm 918 causes the locking pin 920 to release from the flange portion 922 and extend out of the aperture 924. The movement of the second latch arm 918 also causes the entire latch 912 to rotate such that the latch spring 928 reorients and biases the latch 912 toward the first position.
FIG. 25 shows the latch 912 in the first position following still further rotation of the product gate 670 to an angle α3 corresponding to a fully open position of the product gate 670 (i.e., the product gate 670 cannot rotate any further). The angle α3 may be within a range of about 80 degrees to about 110 degrees. As is shown, the angle α3 may be about 95 degrees, although other suitable angles may be used. As is shown, the first latch arm 916 and the cam tracks 914 engage one another and cooperate to restrict rotation of the product gate 670 toward the open position. The latch spring 928 biases the latch 912 to maintain the first position. Meanwhile, the locking pin 920 is in the first position allowing rotation of the product gate 670 toward the closed position.
FIG. 29 shows the latch 912 in the first position following rotation of the product gate 670 toward the closed position. As is shown, the locking pin 920 is in the first position allowing further rotation of the product gate 670 toward the closed position. Meanwhile, the first latch arm 916 and the cam tracks 914 continue to engage one another and cooperate to restrict rotation of the product gate 670 toward the open position. As the product gate 670 is further rotated toward the closed position, the locking pin 920 remains in the first position and travels along the radially outer edge of the flange portion 922. The product gate 670 ultimately returns to the closed position shown in FIGS. 13 and 15, and the product locking system 910 returns to the locked configuration shown in FIGS. 22 and 26.
It should be apparent that the foregoing relates only to certain embodiments of the present application and that numerous changes and modifications may be made herein by one of ordinary skill in the art without departing from the general spirit and scope of the invention as defined by the following claims and the equivalents thereof.
