[0001] The present invention relates to a vending machine with trays.
[0002] As used herein, the term vending machine with trays means a vending machine comprising
a storage area, possibly refrigerated, containing products offered for sale, which
are arranged in orderly rows on trays.
[0003] In terms of structure, such vending machines comprise a cabinet, which is closed
by a front wall, usually having a transparent area, a plurality of trays accommodated
inside the cabinet in the storage area, a drop channel situated between the trays
and the front wall and a pickup station communicating with the drop channel, and through
which the user can pick up the selected product.
[0004] The trays are usually supported by special horizontal guides, such that they can
be partially pulled out of the storage area, to facilitate the task of the operators
in charge of replenishing the vending machine. These guides are rigidly joined to
uprights located at the sides of the storage area. Particularly, the storage area
is delimited by two vertically-extending side partitions facing the storage area,
a substantially horizontally-extending bottom wall, a top wall, also extending horizontally,
and a vertically-extending rear wall. The above mentioned uprights having the horizontal
tray guides connected thereto are supported by the side partitions and are connected
to the latter, usually by rivets. Therefore, the uprights are placed behind the side
partitions, i.e. on the side facing away from the storage area. The side partitions
and the uprights are rigidly joined to the frame of the vending machine by screws
or the like.
[0005] Service spaces (delimited at their sides by the uprights) are usually defined behind
the respective side partitions, and may be used for various purposes, e.g. for the
passage of wiring to supply power to displays on the trays, or the passage of cooled
air for the storage compartment, or other purposes.
[0006] These two service spaces may be reconfigured in case of reconfiguration of the storage
area. The reconfiguration of the storage area is a task that includes, for example,
repositioning the trays at different heights (to accommodate a change of format of
the products offered for sale) and, as a result, changing the wiring arrangement of
the trays, or reconfiguring the temperature at which the space occupied by the tray
has to be maintained. The reconfiguration of the service spaces necessarily requires
removal of the side partitions for access to wiring (in the first example) or for
replacement (in the second example). This is because the temperature at which a tray
has to be maintained is given, in the vending machines in which cooled air flows in
the service space, by the density (and/or shape and/or size) of holes formed in the
side partitions level with the tray. Therefore, it shall be understood that a redistribution
of temperatures within the storage compartment will require the side partitions to
be replaced with side partitions having an adequate distribution of holes.
[0007] The reconfiguration of the service spaces, and particularly the removal of the side
partitions of the frame is a task that requires a skilled operator as well as a non-negligible
down time. Indeed, it requires removal of the horizontal tray guides and then of the
side partitions, while taking care that the threads of the frame holes are not damaged,
such that the same holes may be used during the next mounting operation. If reconfiguration
does not require replacement of the side partition, the latter may be mounted back
to the frame. If replacement of the side partition is required, then a new panel shall
be provided, with the uprights integrated therein.
[0008] Also, the gap reconfiguration task cannot be carried out by the operators in charge
of replenishing the products offered for sale, as it requires equipment (such as screw
drivers, possibly self-drilling screws, riveters, drills, and the like) that do not
form part of the equipment of such operators. Therefore, the work of two operators
shall be coordinated for a change of format of the products offered for sale, which
will entail obvious consequences in terms of operation readiness.
[0009] In light of the above, the object of the present invention is to provide a vending
machine with trays that can obviate the above mentioned prior art drawbacks.
[0010] This object is fulfilled by a vending machine with trays as defined in one or more
of the annexed claims.
[0011] Further features and advantages of the vending machine with trays of this invention,
will be apparent from the following description of one preferred embodiment thereof,
which is given by way of illustration and without limitation with reference to the
accompanying figures, in which:
- Figure 1 shows a perspective view of a vending machine with trays of the present invention,
- Figure 2 shows a side view of a detail of the vending machine of Figure 1,
- Figure 3 is a partially sectional perspective view of a detail of Figure 1.
[0012] Referring to the accompanying figures, numeral 1 generally designates a vending machine
of the present invention.
[0013] The vending machine 1 comprises a frame 2 that defines a storage compartment 3 for
products to be dispensed.
[0014] The frame 2 comprises outer walls 2 a, namely a top wall, a bottom wall, a rear wall
and two side walls, which define the footprint of the vending machine.
[0015] The vending machine 1 further comprises a front panel 4 that closes the frame 2.
Particularly, the front panel 4 is hinged to the frame 2 to allow the front panel
4 to be opened and closed for product loading and maintenance purposes.
[0016] In the preferred embodiment of the invention, the storage compartment 3 is refrigerated
by refrigeration means located in a lower area of the frame. In this respect, the
storage area 3 is thermally insulated from the rest of the vending machine by insulating
material placed between the outer walls 2a of the frame, namely the walls encircling
the storage compartment 3, and counter walls 2b (see Figure 3). The counter walls
2b are placed at least at a back wall, a top wall and two side walls of the storage
compartment 3. It shall be noted that the counter walls placed at the top and back
walls of the storage compartment 3 are themselves the top and back walls of the storage
compartment 3. The side walls of the storage compartment 3 are defined by side partitions
5, located at such a distance from the corresponding counter walls 2 as to define
two respective service spaces 6 (as shown in the partially sectional view of Figure
3).
[0017] In the preferred exemplary embodiment of the invention, the service spaces have the
purpose of controllably conveying cooled air from the lower section of the vending
machine into the storage compartment 3. For this purpose, the side partitions 5 are
formed with a plurality of holes 5a, whose size, arrangement and density define the
operating temperature of the corresponding area of the storage compartment 3. The
service spaces 6 may be configured to serve functions other than that described above,
such as containing electrical wiring and connectors to supply power to power-consuming
units located in the storage compartment 3.
[0018] The products to be dispensed by the vending machine are placed on trays 7 (as diagrammatically
shown in Figure 1). Particularly, the vending machine 1 comprises a plurality of trays
7 which are placed in the storage compartment 3 one above the other. Each tray 7 has
a plurality of seats (not shown) for holding the products to be dispensed. The front
panel 4 of the vending machine may comprise a selection portion 8, for selection of
the product to be dispensed, and an exposure portion made of a transparent material,
for direct display of the products contained in the trays 7. A drop channel is defined
between the trays 7 and the front panel 4, where the products dispensed by the trays
7 are intended to be dropped in. In the preferred embodiment of the invention, the
trays 7 are equipped with product dispensing members, which are adapted to displace
the products from their seats on the tray 7 to the drop channel. For enabling the
user to pick up the selected product, the vending machine 1 comprises a pick-up area
9 (see Figure 1), having an opening closed by a door to allow and prevent access to
the pick-up area 9.
[0019] The trays 7 are mounted to guides 10, as diagrammatically shown in Figures 2 and
3. The guides 10 may be, for instance, of fixed type and act as rails, or of telescopic
type. Irrespective of the specific type of guide 10 in use, at least one pair of guides
10 is provided for each pull-out tray 7, and each guide operates on one of two opposed
sides of the tray. The guides 10 are oriented horizontally, i.e. extend along a horizontal
direction X. Each guide 10 is rigidly joined to a pair of uprights 11 which extend
in a vertical direction Y. The uprights 11 are placed inside the storage compartment
3 and directly faces therein. The uprights 11 are attached in pairs to opposed counter
walls and particularly the counter walls 2b which face the side partitions 5 and form
the service spaces 6. Particularly, a first upright 11 is located proximate to the
front panel 4 and a second upright is located proximate to the back wall of the storage
compartment 3.
[0020] Each side wall 5 extends between two uprights 11 without overlapping them, i.e. is
interposed between two uprights without extending over them. The horizontal guides
10 are rigidly joined to the uprights 11 and hold the side partitions 5 in position
between the uprights. Thus, the panels 5 need no further connection to be held in
position. In other words, the side partitions 5 of the present invention have no load-bearing
function, unlike prior art arrangements, in which the side walls have the function
of supporting the uprights and the guides fastened thereto by screws. When the guides
10 are removed (as required to reconfigure the storage compartment 3), the side partitions
5 become readily accessible and removable without requiring any complex and delicate
action to remove screws, rivets or the like. Spacers are provided between the side
partitions 5 and the counter walls 2b to provide the required service space. These
spacers may be replaced or assisted by parts of the side partition itself (appropriately
bent or shaped).
[0021] In order to avoid that the removal of all the guides 10 may cause accidental displacements
or failures of the side partitions (which are no longer supported by the guides),
attachment members 12 (as diagrammatically shown in Figure 2) are provided to be operative
between the side partitions 5 and their respective counter walls 2b of the frame 2,
These attachment members 12 are configured to require no use of tools (screw drivers,
wrenches, or else) or further connection members (screws, rivets, nuts or the like),
such that they may be actuated by the operator in charge of replenishing the vending
machine. In the preferred embodiment of the invention, the attachment members 12 comprise
a magnet and a ferromagnetic element, one of them being rigidly joined to the counter
wall 2b and the other being rigidly joined to the side partition 5 on the side that
faces the counter wall 2b. It shall be noted that the magnet and the ferromagnetic
element may also form the above mentioned spacer between the side partition and the
counter wall. Preferably, the attachment members 12 are located in a top end portion
of the side partitions.
[0022] In the embodiment as shown in the accompanying figures, the side partitions 5 comprise
a substantially horizontal panel 5b which at least partially defines the base wall
of said storage compartment 3, as diagrammatically shown in Figure 3.
[0023] For an even easier removal of the side partition 5, the horizontal guides 10 are
adapted to be attached to the uprights 11 by means of appendages of the guides which
fit into through openings 11a of the uprights. For this purpose, each guide 10 comprises
appendages 12 that are adapted to be freely introduced into respective through openings
11a in the uprights 11 (Figure 2). As used herein, the term "freely introduced" is
intended as a direct introduction, which is obtained without using auxiliary tools
or devices and is completely reversible. Therefore, these appendages fit into the
openings of the uprights and allow the guides to be mounted and removed without using
tools such as screw drivers or the like and without using screws, rivets and the like.
[0024] It shall be appreciated from the foregoing description that the vending machine of
the present invention can obviate the above mentioned prior art drawbacks, as the
side partition can be readily removed even by operators that have no special equipment
(such as the operators in charge of replenishing products in the trays of the vending
machine).
[0025] Those skilled in the art will obviously appreciate that a number of changes and variants
may be made to the invention as described hereinbefore to meet specific needs, without
departure from the scope of the invention, as defined in the following claims.
