Description: 1 DISPENSING MEANS FOR VENDING MACHINE TECHNICAL FIELD The present invention relates to a dispensing means for use in a vending machine for selectively dispensing containers having a circular cross sectional shape. BACKGROUND ART Vending machines are in common usage throughout the world and generally include a plurality of parallel upright vending channels in which are stored a plurality of soft drink containers having a circular cross-section. The vending channels can be in fluid communication with a refrigeration system to allow refrigerated air circulate and cool the soft drink containers. Various forms of dispensing means are located at the lower end of each channel which allow for single dispensing of the required soft drink following payment and selection. In the vending industry it is usual for a vending machine to be particularly constructed for one configuration of vending channels and with particular allocated dispensing means limited to dispense containers only from a predetermined vending channel. The dispensing means must be purpose built therefore not allowing for easy and cost effective retrofitting of a plurality of dispensing means. Access to the dispensing means for service of various parts of the vending machine, is generally limited and requires the vending machine to be out of operation for a considerable time. As vending machines are usually refrigerated, the machine is not commercially useable until expiration of a further down time in which the containers must be sufficiently refrigerated following completion of the service or repair of the vending machine. Another problem of known vending machines is the need for a plurality of vending channels to be able to hold different quantities of different types of soft drinks so that a large quantity of the most popular soft drink is available while still allowing smaller quantities of 2 the less popular soft drinks. Also vending machines generally cannot cater for a range of sizes of containers. It is therefore an object of the invention to provide a vending machine that overcomes or ameliorates one or more of the above problems by providing more flexibility and accessibility of a vending machine and its components. It is also an object of the invention to provide a vending machine with an improved dispensing means.

MODE FOR CARRYING OUT THE INVENTION 7 According to one aspect of the invention as shown in Figures 1 to 5, there is provided a vending machine 1 1 including a plurality of vending channels 13 defined by parallel upright walls 15 spaced across an upper part of the vending machine 1 1. Each wall 15 of the vending machine defining the vending channels 13 ends at a common lower height with escape openings 16 at the lower ends of each vending channel 13. A plurality of circular cross sectional containers, being cans or bottles, can be stacked in a lying position within the vending channels 13 and can escape through respective lower escape openings 16. The vending channels 13 include vertical dividers 19 which divide the depth of each vending channel 13 into a plurality of separate defined portions of vending channels located respectively behind each other. Therefore a vending machine having seven laterally adjacent vending channels 13 can be multiplied to twenty-one vending channels by vertical dividers 19 separating each vending channel 13 into 3 channels located respectively behind each other. Different combinations of portions of vending channels can also be configured to allow various depths that accommodate various sized containers. A dispensing means 21 is located below the vending channels 13 and adjacent the escape openings 16 but is separate therefrom to allow for retrofitting or removal for repair or servicing. The dispensing means 21 includes a plurality of releasing mechanisms 22 associated with each vending channel 13 or portion of vending channel to allow separate dispensing of containers from each channel or part . The releasing mechanisms 22 are located in the path of containers escaping through the escape openings 16 of the vending channels 13. A plurality of drop chutes 23 intermediate the releasing mechanisms 22 and the escape openings 16 of the vending channels 13 deflect the containers towards the releasing mechanisms 22. The releasing mechanism 22 includes a rocking body 26 located in the path of containers escaping through the escape opening 16 of each respective vending channel 13 8 and which in combination with the drop chute 23 prevents the lowest container being released. The subsequently higher containers are thereby retained above the lowest container. The rocking body 26 includes a planar top abutting arm 28 extending from one side of 5 an intermediate body portion and laterally offset to a lower straight arm extending from an opposite side and which in combination with the intermediate body forms a cradling arm 29 in the shape of a reversed reclined L-shape. The abutting arm 28 and lower straight arm of the cradling arm being at an obtuse angle to the intermediate body portion. Each rocking body 26 is pivotally mounted below the surface of the abutting arm 28 10 and cradling arm 29 and is able to be latched or unlatched by a solenoid 31 such that in a first state the solenoid 31 latches the rocking body 26 in a position such that the abutting arm 28 is located a distance from the end 24 of the drop chute 23 which is smaller than the cross sectional size of the container falling from the escape opening 16 of the vending channel 13. The lowest container A is thereby held in position between the abutting arm 28 and the end 15 24 of the drop chute 23. By control of the solenoid 31 the rocking body 26 is in its second state and unlatched results in the weight of the lowest container A to force the rocking body 26 to pivot around the pivot 27 away from the end 24 of the drop chute 23 to enlarge the opening such that the lowest container A falls into the cradling arm 29. The weight of the lowest container and a return spring rotates the rocking body 26 back to the first position 0 releasing container A through outlet 36 of the dispensing means 21 and causes the abutting arm 28 to engage the second lowest container B and retain it in the lowest position with the solenoid 31 latching the rocking body 26 into the retaining position in its first state. By having separate controls of a plurality of releasing mechanisms 22 located behind each other in a particular vending channel 13, it is possible to divide the vending channel 13 9 into a plurality of separate portions which can accommodate various lengths of containers. As shown in Fig. 4, it is possible to dispense three separate cans with each releasing mechanism controlling the release of each row of cans, when three releasing mechanisms 22 including solenoids 31 and rocking bodies 26 are located behind each other. In another configuration it is possible to dispense two rows of bottles lying behind each other which are longer than cans but can be dispensed by activation of the respective front and rear releasing mechanisms while the intermediate releasing mechanism is not active. In a still further configuration two coacting adjacent releasing mechanisms release a bottle which is the size of two releasing mechanisms with cans being dispensed by the third mechanism. In another configuration a bottle the length of all three mechanisms can be released by coacting three adjacent releasing mechanisms. In order to accommodate the various circumferential sized containers in the dispensing means an adjusting rod 41 as shown in Fig. 2 can be inserted through the front of the dispensing means to engage with respective drop chutes 23 so as to ensure by positioning of the adjusting rod 41 in position one or position two the relative position of the drop chute 23 as shown in Fig. 5 can be adjusted so that the distance between the end 24 of the drop chute and the abutting arm 28 in its first position is sized smaller than the diameter of the respective containers and thereby is able to hold the containers in a retaining position. As well as being able to separately dispense containers of various lengths, the arrangement of the releasing mechanisms 22 behind each other below a single vending channel 13 allows the releasing mechanisms 22 to be mounted on a single carrier 39 that is separably removable from the dispensing means 21 by being slidable out through a front opening 40. This allows for any servicing or replacement of any one releasing mechanism 22 on the entire carrier 39 of releasing mechanism 22. 10 Referring to Fig. 6, 7 & 8 there is shown an alternative control means of releasing mechanisms whether they be the releasing mechanisms 22 of the first embodiment including the rocking body 26 and drop chute 23 or releasing mechanisms 41 including a pair of opposing drop rocking bodies 42 which on an upper outer side has a container holding face 43 able to engage the lowermost container in a vending channel 13 and pivotally rotatable so as to dispense the required container from the vending channel or other releasing mechanism. In Figure 6 there is shown three release mechanisms 41 located behind each other to dispense containers from one or more defined portions of a vending channel 13 located behind each other. The control and movement of the plurality of drop rocking bodies 42 around their respective pivots by elongated latching levers 46 including rods 47 extending parallel from each release mechanism 41 through a central lower part of the front release mechanisms 41 to the front of the dispensing means 21 and ending with cams 48. A solenoid bank 51 which is drivable along a linear drive 52 extending across the front of the dispensing means 21 allows the solenoid bank 51 to be located and engage the cams 48 of the latching levers 46 associated with any one of the seven laterally adjacent vending channels 13. By the structure of the linear drive means this can be separably removable from the dispensing means 21. As shown in Fig. 7 when three releasing mechanisms including drop rocking bodies 42 are located behind each other, it is possible to dispense three separate cans with each releasing mechanism controlling the release of each row of cans. In another configuration it is possible to dispense two rows of bottles lying behind each other which are longer than cans but can be dispensed by activation of the respective front and rear releasing mechanisms by the respective latching levers 46 while the intermediate releasing mechanism is not active. In a still further configuration two adjacent releasing mechanisms is jointly coactivated to 1 1 release a bottle which is the size of two releasing mechanisms with cans being dispensed by the third mechanism. In another configuration a bottle the length of all three mechanisms can be released by coactivating three adjacent releasing mechanisms.
