Abstract
Description
- The present invention refers to an automatic vending apparatus for the sale of goods of various kind that require being stored and preserved under differentiated temperature conditions. In particular, it refers to an improved cooling system for an automatic vending apparatus of this kind.
- An automatic vending apparatus has essentially the appearance of a cabinet, in the interior of which there is arranged a vertical-axis drum that is rotatably driven by an electric motor. Such a drum carries a plurality of horizontal shelves, which are in turn subdivided into individual compartments by vertical partitions: the items stored there for vending, and which require being preserved at adequately low temperatures, are arranged in such compartments on said shelves. The drum is mounted around a hollow central column, through which the cooling air is caused to flow upon being cooled down by a refrigeration arrangement contained in the cabinet and usually installed in the base thereof. Through proper apertures, the refrigerated air flows from the hollow space in the central column into the compartments containing the items to be sold. The return flow of the air towards the refrigeration arrangement is brought about by such an air being drawn in through appropriate channels defined by vertical walls provided in the cabinet between the drum and the side walls of the same cabinet.
- An automatic vending apparatus of such a kind is described in the patent publication US 4,831,841. However, the purpose of the solution described in said patent is to ensure a uniform product storage temperature in all of the storage compartments of the apparatus. As a result, such a vending apparatus enables only products of a same kind, or at most products requiring to be stored under similar temperature conditions, to be stored there for vending purposes. Furthermore, it should be noticed that the technical solution described in the above mentioned publication cannot anyway ensure a uniform temperature throughout the storage compartments of the vending apparatus, since the flow of the cooling air is actually affected to a considerable extent by the hindrances it meets with, as represented in particular by the loads of products that are continuously varying in the various compartments owing to the successive product withdrawals.
- It would on the contrary be desirable, and it actually is a main purpose of the present invention, to provide a much more versatile automatic vending machine that is capable of enabling products of different kinds requiring different storage temperatures to be sold therethrough. This is for instance the case of various food items, such as freshly prepared sandwiches or packaged snacks, which are contained in single-dose packages, and also drinks contained in cans or bottles. For the desired result to be obtained, the need arises for the possibility to be provided for the temperature to be adjusted in a differentiated manner in the various compartments of the storage shelves, or at least in definite, preferably adjustable-volume zones inside the vending apparatus.
- According to the present invention, this aim is reached in an automatic vending apparatus of the afore described kind, in which means are provided for adjusting the flow of refrigeration air, said means being mounted on the central hollow column and being adapted to create homogeneous, but differentiated temperatures in a plurality of zones arranged above each other in the storage room of the vending apparatus, as this is recited in the main appended claim.
- As this will become apparent further on in this description, the basic idea behind the present invention may be implemented in a variety of different embodiments.
- The features and advantages of the present invention will anyway be more readily and clearly understood from the description that is given below by way of non-limiting example with reference to the accompanying drawings, in which

- Figure 11 is an enlarged cross-sectional view of the lower portion of the vending apparatus illustrated in Figures 9 and 10.
- An automatic vending apparatus for the sale of different products, which are usually contained in packages, cans or the like, is generally constituted by a parallelepiped cabinet 20 (Figure 1) which defines an
inner storage room 50 and a base portion 51 (Figure 2). Thestorage room 50 is closed on its front side by adoor 21, which is provided with a plurality of clear, ie. see-throughglazed wickets 22 to ensure visibility of the products stored inside the vending apparatus and to enable the same products to be removed therefrom. On thedoor 21 there are provided selection means 23 (Figure 1) for the selection of the product to be dispensed, whereas payment means 24 are preferably arranged on a front panel of the cabinet. These means are of a kind that is generally known in the art, so that they do not require any further detailed description. - Inside the
storage room 50, the products are arranged on a vertical-axis drum 25 (Figure 2) formed by a plurality ofhorizontal shelves 26, which are mounted on a centralhollow column 27. Theshelves 26 are subdivided into individual compartments by means of vertical partitions 28 (Figure 3). Thedrum 25 is rotatable owing to the action of an electric motor-reduction gear unit 29 (Figures 6 and 7) mounted in the base of the vending apparatus and provided with anoutput shaft 30. The latter carries apinion 31 that is in gear with atoothed disk 32, which is attached to the lower end portion of thecolumn 27 and which rests on thebottom 33 of the storage room by means ofwheels 34. As a result, when a product is selected for vending, the motor-reduction gear unit 29 causes the drum to rotate until the compartment containing said product is brought into the product dispensing position in correspondence of the respective wicket 22 (Figure 3). - In the
base 51 of thecabinet 20 there are installed the devices needed for cooling, ie. refrigerating the air and circulating it inside the vending apparatus to the purpose of preserving the products stored there at the required temperature. The refrigeration devices comprise a refrigerating circuit that is normally provided with acompressor 35, anevaporator 36, acondenser 37 and a fan 38 (Figures 6 and 7). The air circulation is on the contrary brought about by afan 39 which delivers the air, through anaperture 40 provided in thebottom 33 of the storage room, into the centralhollow column 27 of thedrum 25. The air rises along thecolumn 27 and distributes radially over thevarious shelves 26 by flowing through corresponding arrays of ports provided in the cylindrical wall of the column. The air then returns to the refrigeration unit in the base of the vending apparatus by flowing back through the free space comprised between the periphery of thedrum 25 and the inner walls of the storage room 50 (Figure 2). - In order to adjust the flow of the cooling air in such a manner as to create substantially homogeneous, but differentiated temperatures in various zones arranged above each other in the
storage room 50, on the hollowcentral column 27 there are mounted a plurality ofsleeves 60, which are provided with passing-throughapertures 61, corresponding to a plurality ofapertures 62 provided in the wall of the column 27 (Figure 4). Each one of saidsleeves 60 is connected by pin-slot coupling means to alever 63 which is pivotally hinged on to the wall of thecolumn 27, in such a manner that a rotation of thelever 63 about its horizontal hinge-on axis translates into a rotation of thesleeve 60 about its vertical axis coinciding with the axis of thecolumn 27. As a result, theapertures 61 of eachsleeve 60 can take, relative to thecorresponding apertures 62 of thecolumn 27. a position of full closure (Figure 5A), or a position of partial opening (Figure 5B), or a position of full opening (Figure 5C). To each one of these positions there corresponds a different condition of the flow of cooling air, as this is best shown by the arrows in Figures 5A to 5C. - As an alternative thereto, it can be readily appreciated that the
sleeves 60 can be mounted and actuated so as to slide longitudinally along thecolumn 27, instead of rotating about the same column. This different mechanical solution can anyway be easily and readily implemented by anyone skilled in the art. - The
sleeves 60 are actuatable manually and individually, but can clearly be provided with an automatic actuation system and controlled, for instance, by means of a thermostatic device. Furthermore, they can also be actuated in clusters or groups, for instance by connecting a plurality oflevers 63 together by means of a bar. - In a preferred manner, to each
such sleeve 60 there is associated an indicating device 64 (Figure 4), which may for instance be constituted by a jumper-type index, or the like, that is adapted to cooperate with corresponding reference nicks provided on the edge of the sleeve. Thedevice 64 enables the precise, actual opening or closing condition of the apertures for the passage of the cooling air on theindividual shelves 26 to be most conveniently and readily verified. - A second, more complete and sophisticated embodiment of the present invention calls for the addition of an intermediate partitioning diaphragm 42 (Figure 8) inside the storage room 50 (Figure 8). This
diaphragm 42 is preferably constituted by a first portion attached to the centralhollow column 27, and a second portion attached to the inner wall of thestorage room 50. The position of thisdiaphragm 42 is variable along the height of thestorage room 50 so as to create two distinct zones arranged above each other and kept at different temperatures. The lower zone may for instance be used to store fresh products to be kept at a temperature of 3 to 4°C, whereas the upper zone may be used to store packaged products (ie. the so-called snacks) or drinks in bottles or cans to be kept at temperatures of anywhere between 8 and 15°C. - In order to prevent the lower zone to be negatively affected by a return flow of warm air, it may prove adequate to provide a
channel 43, worked out in the wall of thestorage room 50, for directly connecting the upper zone of the storage room with the refrigeration unit installed in thebase 51 of the vending apparatus. Throttling the flow of cooling air circulating in thestorage room 50 keeps of course being made possible thanks to the presence of theadjustable sleeves 60 mounted on the central column, in the same way as described afore with reference to the first embodiment. - The constructional configuration of this embodiment calls for the use of just a single temperature probe (not shown) to control the more sensitive zone of the storage room, ie. the lower zone holding the fresh food products.
- This second solution is effective in ensuring that the return flow of the air from the upper zone of the storage room is fully separated from the flow of air circulating in the lower zone. This therefore enables a greater stability of the colder temperature, ie. the storage temperature actually required in the lower zone of the storage room, to be obtained. This solution is found to be of particular advantage in the case in which a distinct, clear differentiation is required among the temperatures prevailing in various zones of the storage room.
- In a third embodiment of the vending apparatus according to the present invention (Figures 9 and 10), the differentiated-temperature zones in the
storage room 50 are fed separately through at least twodistinct channels hollow column 27. In a preferred manner, thesechannels channel 44 forms the passage of the cooled air towards the upper zone of the storage room. Thechannel 45 is plugged on top, in correspondence of theintermediate diaphragm 42, so as to be able to deliver the cooling air into the lower zone of the storage room. - The
channels aperture 40 in the bottom 33 of thestorage room 50 and, at the inlet openings thereof, there are providedrespective throttle valves 46 and 47 (Figure 11) that are arranged downstream of thedelivery fan 39. By correspondingly selecting, either manually or by automatic control, the operating setting of thevalves storage room 50 to be refrigerated. In this case, the need arises for two temperature probes (not shown) to be used to control the two zones at different temperatures. - Use of the throttling
sleeves 60 of the afore described embodiments (not shown in Figures 9 and 10 for reasons of greater simplicity in the illustration) is made also in this third embodiment of the present invention. These sleeves make it possible for the air flow to be more specifically adjusted on thevarious shelves 26 so as to create further differentiated zones within each one of said two zones at different temperature. - It will of course be appreciated that the above described automatic vending apparatus may be the subject of a number of further modifications or variants without departing from the scope of the invention.
