Definitions
- a vend mechanism for back-to-back staggered stacks of cans or for a single staggered stack of bottles has opposed vend gates for each stack.
- Each pair of opposed vend gates is actuated by a rotary cam and these cams are rotated by a single shaft which extends beneath the stacks of cans or bottles and acts to support the lowest can or bottle in the stack against the adjacent gate.
- An electric motor rotates that shaft in 90 increments for back-to-back staggered stacks of cans and rotates the shaft through 180 increments for a single staggered stack of bottles.
- a limit switch in the motor circuit is actuated by adjustable tabs rotated by the shaft to obtain the desired increments of rotation.
- One of the pairs of end gates is provided with a releasable portion when bottles are to be vended to prevent the bottle cap from sticking against the adjacent vend gate and blocking the vend mechanism.
- various vend mechanisms have been suggested for individually dispensing one bottle or one can at a time from staggered stacks of cans or bottles and from such stacks in back-to-back relationship.
- Various cam mechanisms have been proposed for actuating release mechanisms for this purpose.
- the following patents are considered to be representative of such dispensing mechanisms: U.S. Pat. Nos. 1,944,499; 2,267,525; 2,438,503; 2,585,011, 2,638,396; 2,834,512; 2,941,643; and 3,074,593.
- each of these patents operate a vend mechanism through cams and in Johnson and in Holt the vend mechanisms are driven in 90 increments so that the bottles or cans are dispensed alternately from side-byside stacks or from back-to-back staggered stacks.
- the cams for the release mechanism are at each end of a motor driven shaft while in Johnson the link arms and crank arms of the release mechanism are at the same end of the driving shaft and are connected to it through gearing.
- the Kemp patent discloses cams similar to those employed in the present concept.
- This prior art does not disclose the concept of supporting the cans or bottles in staggered stacks on the drive shaft for the cams against the adjacent vend gate and rotating the drive'shaft in desired increments to dispense alternately from the stacks when the stacks are back-toback and to dispense alternately on each side of the shaft for each stack.
- FIG. 1 is a front view of the vend mechanism
- FIG. 2 is a rear view of the embodiment of FIG. 1;
- FIG. 3 is a view from above of the embodiment of FIG. 1 with the staggered stacks of cans or bottles omitted for clarity;
- FIG. 4 is a side elevation of the lower portion of the embodiment of FIG. 1 as seen from the right in FIG. 1;
- FIG. 5 is a side elevation corresponding to that of FIG. 4 with the driving mechanism and side panel omitted and arranged for dispensing a staggered stack of bottles;
- FIG. 6 is a detail of a cam and tabs disposed for actuation of the limit switch for 180 increments of rotation of the cam shaft used when dispensing a bottle at a time from a staggered stack of bottles;
- FIG. 7 is a figure similar to FIG. 6 showing the tabs disposed for 90 increments of rotation of the cam shaft single staggered stack with the lowermost bottle of the staggered stack resting on the cam drive shaft and against the adjacent vend gate.
- the prior art does not disclose mechanism for dispensing bottles from staggered stacks having a portion of an adjacent vend gate which may readily be freed from actuation with its vend gate to prevent a bottle cap from sticking in the vend gate mechanism and blocking the machine.
- Tray 10 is provided with front wall 11 and rear wall 12 as well as with turned side walls 13 and 14.
- a motor base plate 15 is bolted or otherwise secured to front wall 11 and a suitable electric motor 16 is secured thereto.
- Rear wall 12 supports upstanding plate 17 and a corresponding plate 18 is secured in spaced parallel relationship thereo and with plate 15 by brackets 19 and 20. (FIG. 4).
- Side plates 21 and 22 extend between and are secured to plates 17 and 18 and are spaced apart to receive cans or bottles 23 in staggered stack as seen in FIGS. 1, 2 and 5.
- Plates 21 and 22 are of sufficient length to receive two staggered stacks of cans back-to-back or one staggered stack of longer bottles as seen in FIG. 5. Plates 21 and 22 are turned inwardly at each end as at 24, 25, 26 and 27, respectively, to prevent the cans or bottles from longitudinal movement and are inwardly directed at 28 and 29 to assure that only one can or bottle at a time from a stack is in dispensing position.
- a cap 30 fits on top of plates 21 and 22 to hold them in position and the several plates may be aperturcd to reduce the weight of the structure.
- a cam drive shaft 31 is rotated by motor 16 and extends through plates 17 and 18 medially between the lower ends of extensions 28 and 29 of side plates 21 and 22. As will be seen in the drawings, the lowermost can or bottle in each staggered stack rests in part on shaft 31.
- a front oblate hollow cam 32 is mounted for rotation on and with shaft 31 in front of plate 18 and a rear oblate hollow cam 33 is mounted for rotation on and with shaft 31, cams 32 and 33 being spaced by an angle of 90 in the direction of rotation of shaft 31, counterclockwise in FIG. 1.
- the lower end of side 21 is provided at front and rear with outstanding lugs 34 and 35 supporting between them a pivot shaft 36.
- the lower end of side 22 is provided at front and rear with outstanding lugs 37 and 38 supporting between them and a pivot shaft 39.
- Vend gates 40 and 41 are mounted for rotation on shaft 36 and similar vend gates 42 and 43 are mounted for rotation on shaft 39.
- Vend gate 40 has cam follower 44 mounted thereon and engaging in cam 32.
- Vend gate 42 has cam follower 45 mounted thereon and also engaging in cam 32.
- Vend gate 41 has cam follower 46 mounted thereon and engaging in cam 33 and vend gate 43 has cam follower 47 mounted thereon and also engaging in cam 33.
- Vend gates 41 and 43 are split, as clearly seen in FIGS. 4 and 5, and each gate has portion 48 provided with finger 49 and auxiliary portion 50 normally held inside finger 49 by compression spring 51 when backto-back staggered stacks of cans are to be vended.
- the auxiliary portion or gate 50 is moved to the left when adjusting the mechanism against spring 51, as seen in FIG. 4, and portion 50 is arranged to the position seen in FIG. on the outside of finger 49 for reasons which will appear more fully hereinafter.
- Shaft 31 should be rotated in 90 increments when the mechanism is to dispense one can at a time from back-to-back staggered stacks of cans.
- the electric circuit for energizing motor 16 as disclosed in US. Pat. No. 3,486,601 referred to above includes a switch 52 actuated by arm 53. Arm 53 is inturn engaged and actuated by cam shoulders 54 and 55 (FIG. 7) carried by base 56 secured for rotation on shaft 31 and by shoulders 57 and 58 carried by base 59 mounted loosely on shaft 31 and held in four prongs 60, 61, 62 and 63 carried by base 56 by spring 64 which surrounds shaft 31 and bears against plate and base 59.
- cam shoulders 54 and 55 FIG. 7
- motor 16 should rotate shaft 31 through 180.
- the mechanism is adjusted by sliding base 59 against the action of spring 64 out of prongs 60-63 and then rotating base 59 until shoulders 57 and 58 lie within shoulders 54 and 55 as seen in FIG. 6. Thereafter, spring 64 will hold base 59 in prongs 60-63 and only shoulders 54 and 55 will actuate switch 52 for each 180 rotation of shaft 31.
- a guide plate 64 is placed within side plates 21 and 22 to loosely engage the bottle caps and keep the bottles in position. Plate 64' is held in place by upper comb 65 and lower'comb 66 which frictionally engage between side plates 21 and 22.
- a plurality of the mechanisms as above-described can be used in a single refrigerated vending machine so that various flavors of canned or bottled beverages may be vended.
- four such mechanisms may be used to vend four flavors or types of beverages. Some of these mechanisms may vend cans and others bottles or all may vend cans or all may vend bottles. Great flexibility of use is therefore obtained.
- a vend mechanism for back-to-back staggered stacks of cans or a single staggered stack of bottles comprising vertically disposed means for holding said stacks, a lower opening defined by said means beneath the stacks, a pair of opposed vend gates carried by said means partially closing said opening beneath each stack, a shaft extending medially between said pairs of vend gates and medially of said opening, the lowermost can or bottle of the stacks resting on said shaft and against the adjacent one of said vend gates, a cam for each pair of said vend gates mounted for rotation on and by said shaft, and electric motor means for driving said shaft in predetermined increments of rotation, said cams opening and closing said vend gates in predetermined sequence whereby one can or bottle is released for vending for each increment of rotation of said shaft.
