[0001] The present invention relates to a device for storing and dispensing products. This
device may be integrated in a drawer of a dispensing machine such as those commonly
used in offices, schools, hospitals, railroad stations and more in general any public
or private environment in which a product vending service may be provided. In particular,
the device of the present invention is arranged to dispense bottles, cans or similar
products.
[0002] Automatic product dispensing machines, and particularly product vending machines,
are well known in the art. These machines have the purpose of dispensing a product
upon payment by the user. Payment may be made in cash or, more and more frequently,
with electronic money. Dispensing machines can dispense any type of product, most
typically food products such as soft drinks and snacks even though, especially at
airports and railroad stations, different products, such as consumer electronics and
travel accessories, are being increasingly dispensed thereby.
[0003] Devices for storing and dispensing products are known in the field of dispensing
machines. These devices comprise a storage compartment for products. In particular,
the storage compartment has a front area having an opening for dispensing products,
and a rear area, opposite to the front area.
[0004] For example, one type of product dispensing machines comprises a coil within the
storage compartment. Such coil extends from the rear area to the front area. The products
to be dispensed are arranged in a row in the storage compartment, each arranged between
two turns of the coil. By this arrangement, the dispensing operation simply requires
the coil to be rotated about its axis for the product situated at the opening to be
pushed out, and for the other products to be fed in the storage compartment from the
rear area to the front area.
[0005] One drawback of the structure of the coil dispensing system is that it limits the
number of products that can be stored in the storage compartment. The maximum number
of storable products is given by number of turns of the coil, and the pitch between
turns must be necessarily greater than the size of the product, to prevent the mechanism
from jamming.
[0006] US 2009/084812 discloses another type of product dispensing machines, with products arranged in
a row in the storage compartment. In addition to the above discussed storage compartment,
this dispensing machine also comprises a door at the opening of the storage compartment
and a plate opposite to the opening. In particular, the plate contacts the product
in the row that is farthest away from the opening. During dispensing, the door opens
and the product that is closest to the opening is allowed to come out. At the same
time, the plate causes all the row of products to advance toward the opening, and
makes them ready for later dispensing.
[0007] One drawback of this mechanism is that it limits product arrangement to one row.
No element is provided to stop the products in addition to the door, and if the products
were arranged in more than one row, multiple products would be dispensed at the same
time.
[0008] US 2015/102052 discloses a dispensing machine with different rows of products arranged in its storage
compartment. All the products are arranged on a roller, which feeds them during dispensing.
This dispensing machine comprises a stop member, which contacts the product closest
to the opening, and is configured to afford controlled dispensing. In particular,
during dispensing the stop member is disabled and the roller moves thereby causing
the product to come out. As soon as the product has passed, the stop member is enabled
and the roller stops. The device also comprises a dispensing element, which receives
the product that has passed the stop member and lets it fall or guides it to the opening
for dispensing.
[0009] One drawback of this arrangement is that the size and shape of the product must conform
with the above discussed dispensing element, which also requires the dispensing operation
to include an additional step.
SUMMARY OF THE INVENTION
[0010] Therefore, the technical purpose of the present invention is to provide a device
for storing and dispensing products that can obviate the aforementioned prior art
drawbacks.
[0011] In particular, an object of the present invention is to provide a device for storing
and dispensing products that can store a larger number of products in a storage compartment
having a smaller or equal volume. Also, an object of the present invention is to provide
a simpler device that affords quicker dispensing.
[0012] The aforementioned technical purpose and objects are substantially fulfilled by a
device for storing and dispensing products that comprises the technical features as
disclosed in one or more of the accompanying claims.
[0013] More in particular, a device for storing and dispensing products of the present invention
is adapted to dispense products whose predominant axis of extension is the center
axis.
[0014] The device comprises a storage compartment. The storage compartment has a front area
with an opening for dispensing products and a rear area opposite to the front area.
[0015] The storage compartment is configured to accommodate a plurality of products to be
dispensed with their central axes arranged vertically and that products grouped in
two parallel rows. These parallel rows extend from the rear area to the front area
of the storage compartment. The rows are offset from each other so that each product
of each row partially fits between two products of the other row.
[0016] The device 1 comprises feeding means which are configured to contact the product
of each row that is farthest away from the opening, thereby pushing all the products
toward the opening.
[0017] A stop member is situated at the opening to stop both rows of products by abutting
the product that is closest to the opening.
[0018] The device also comprises dispensing means operable on the stop member to disable
it and allow product dispensing. These dispensing means are configured to contact
the product that is closest to the opening and push the product out of the opening.
[0019] This device solves the aforementioned technical problem, as it can dispense products
having an axially symmetrical geometry, arranged vertically and in two offset rows.
This is the most efficient arrangement for this type of products, whereby a storage
compartment having a given volume will be able to contain a larger number of products
than in the prior art.

DETAILED DESCRIPTION
[0021] Referring to the annexed figures, numeral 1 generally designates a device for storing
and dispensing products according to the present invention.
[0022] The device 1 is adapted to dispense the products 100. These products 100 are not
themselves part of the present invention, but will be briefly described to better
illustrate the structure and operation of the inventive device 1.
[0023] Each product 100 has a shape with a center axis "A". In particular, the product 100
extends symmetrically with respect to the axis "A". Preferably, the product 100 has
a cross section transverse to the center axis "A" with a polygonal, or more preferably
circular shape. In the embodiments as described and illustrated herein, the products
100 are embodied by axially symmetric containers, such as bottles or cans, e.g. containing
water and/or beverages.
[0024] Particularly referring to Figure 3, the device 1 comprises a storage compartment
2. The storage compartment 2 has a front area 2a, a rear area 2b opposite to the front
area 2a and a pair of sides 2c, extending from the rear area 2b to the front area
2a. The front area 2a has an opening 3 for dispensing the products 100.
[0025] More in detail, the storage compartment 2 is delimited by a pair of side walls 4
which particularly extend from the front area 2a to the rear area 2b of the storage
compartment 2. In particular, the side walls 4 are located at the sides of the storage
compartment 2. It shall be noted that the aforementioned opening 3 is partially defined
by the side walls 4.
[0026] The storage compartment 2 also has a bottom 5, which has the purpose to support the
products 100. This bottom 5 is placed between the side walls 4. Furthermore, the bottom
5 extends substantially seamlessly from the front area 2a to the rear portion 2b.
[0027] The storage compartment 2 may further comprise a flexible element (not shown), for
example a cable or a spring. Such flexible element is located at the opening 3 and
has the purpose of maintaining the orientation of the products 100 during dispensing.
[0028] According to the present invention, the storage compartment 2 is configured to accommodate
a plurality of products 100 to be dispensed with the central axes "A" of the products
100 arranged vertically. In addition, the products 100 are grouped in the storage
compartment 100 in two rows 101. These rows 100 are particularly parallel and extend
from the rear area 2a to the front area 2b of the storage compartment 2.
[0029] It shall be noted that the rows 101 are offset from each other so that each product
100 of each row 101 partially fits between two products 100 of the other row 101.
In other words, in any central zone of the rows 101, each product 100 contacts two
products of the same row 101, and two products 100 of the other row 101.
[0030] More in detail, the products 100 are fed in the storage compartment 2 from the rear
area 2b to the front area 2a, i.e. is along the rows 101. This will define a direction
of feed "B" of the products 100 oriented parallel to the rows 101.
[0031] It shall be noted that the offset arrangement of the rows 101 causes the products
100 of each row to be unable to slide relative to the products 100 of the other row.
As a result, the rows 101 cannot be fed independently of each other in the direction
of feed "B", but are forced to be fed together. In other words, by simply stopping
the feed of one row 101 both will be stopped.
[0032] In order to move the products 100 in the storage compartment 2, the device 1 comprises
feeding means 19 configured to contact the product 100 that is farthest away from
the opening 3 of each row 101 and push all the products 100 toward the opening 3;
These feeding means 19 are embodied by a movable wall 20 situated between the side
walls 4. The movable wall 20 particularly faces the opening 3. More in particular,
the mobile wall 20 is driven by a first motor 21 between the rear area 2b and the
front zone 2a of the storage compartment 2. The feeding means 19 also comprise a limit
stop sensor (not shown), which has the purpose to disable the first motor 21 when
the movable wall 20 arrives proximate to the opening 3.
[0033] To prevent undesired ejection of products 100 from the storage compartment 2, the
device 1 comprises a stop member 6. This stop member 6 is particularly placed at the
opening 3 and, more in particular, substantially halfway between walls 4. By this
arrangement, the stop member 6 will be able to stop both rows 101 of products 100
by abutting the product 100 that is closest to the opening 3, as shown for example
in Figure 2.
[0034] More in detail, the stop member 6 comprises a wedge 11 placed between the rows 101
of products 100. This wedge 11 has the purpose of stopping the feed of both rows 101.
In operation, wedge 11 is able to move in a direction transverse to the aforementioned
direction of feed "B" of the products 100, to thereby alternately clear the passage
for the products 100 of one row 101 or the other. Further details about the wedge
11 will be provided hereinbelow.
[0035] Particularly referring to Figure 1, it will be appreciated that the device 1 has
dispensing means 7. These dispensing means 7 are operable on the stop member 6, to
thereby disable it and allow dispensing of the products 100. The dispensing means
7 are further configured to contact the product 100 that is closest to the opening
3 and push it out of the opening 3.
[0036] More in detail, the dispensing means 7 comprise a pair of pushing members 8. These
pushing elements 8 are located substantially at the front area 2a of the storage compartment
2. Each pushing member 8 is particularly associated with a respective row 101 of products
100, to thereby contact the foremost product 100 of the respective row 101, in particular
the one directly in front of the opening 3.
[0037] Particularly referring to Figure 5, each pushing member 8 comprises a wheel 9. Each
wheel 9 has a perimeter 9a. The wheels 9 are disposed at the opening 3, in particular
each at a respective side 2c of the storage compartment 2. The center of the wheels
9 is particularly located below the bottom 5 of the storage compartment 2. Referring
to Figure 1, it shall be noted that the wheels 9 partially emerge from the bottom
5.
[0038] More in detail, the wheels 9 are coaxial. In particular, the wheels 9 are rigidly
joined to a shaft 12. As a result, the wheels 9 are adapted to rotate together and
particularly in a direction of rotation "R".
[0039] In order to drive the wheels 9, the device 1 is equipped with a second motor 13 which
is actuated when a product 100 is being dispensed. This second motor 13 is connected
to the wheel 9 via transmission means 14. In particular, the transmission means 14
comprise a toothed edge 15 formed on one of the two wheels 9. Furthermore, the transmission
means 14 comprise a gear 16. This gear 16 meshes with the toothed edge 15, and is
driven by the second motor 13 to rotate the wheels 9.
[0040] Particularly referring to Figure 1, it shall be noted that at least one of the two
wheels has at least one recess 25 particularly formed at its perimeter 9a. Preferably,
this wheel has a pair of recesses 25 located in diametrically opposite positions of
the perimeter 9a. Detection means (not shown) of the type known to the skilled person
detect the passage of the recesses 25 during rotation of the wheels 9 and, upon such
detection, disable the second motor 13.
[0041] Each pushing member 8 further comprises a protrusion 10 connected to its respective
wheel 9. The projection 10 extends into the storage compartment 2. Furthermore, the
projection 10 is located at the perimeter 9a of its respective wheel 9. The projection
10 preferably has an arc shape to conform with part of the perimeter 9a. Preferably,
the projection 10 extends over an angular width that ranges from 30° to 70°, and is
preferably 50°.
[0042] More in detail, each projection 10 comprises a first portion 10a which extends into
the storage compartment 2 to a first length. The projection 10 further comprises a
second portion 10b, which extends into the storage compartment 2 to a second length
which is particularly less than the first length. It shall be noted that the first
portion 10b directly follows the first portion 10a when the wheel 9 moves in the direction
of rotation "R".
[0043] More in detail, each projection 10 has a front edge 23 particularly located at the
first portion 10a. Likewise, each projection has a rear edge 24 located on the second
portion 10b and particularly opposite to the front edge 23. It shall be noted that,
in operation, the front edge 23 is designed to contact the product 100 to be dispensed
to push it toward the opening 3.
[0044] It shall be noted that the bottom 5 of the storage compartment 2 has a pair of slots
17. Each pushing member 8 is associated with a respective slot 17, to extend therethrough
and contact the product 100 to be dispensed. In particular, each projection 10 is
associated with a respective slot 17 to extend therethrough.
[0045] More in detail, each slot 17 is adjacent to a respective side 2c of the storage compartment
2, and is located substantially at the perimeter 9a of the wheel 9 adjacent thereto.
Thus, as the wheel 9 rotates, the projection 10 can extend through the slot 17 and
enter the storage compartment through the bottom 5. It shall be noted that, when the
dispensing means 7 are inactive, one of the front edges 23 is placed substantially
at its respective slot 17.
[0046] In order to cooperate with the stop member 6, each pushing member 8 comprises an
abutment area 18 for the wedge 11. Such abutment area18 is formed on its respective
wheel 9, and is configured to prevent displacement of the wedge 11 in the direction
of its respective wheel 9. The abutment area 18 is particularly arranged to contact
the wedge 11 and/or release the wedge 11 depending on the rotation of its respective
wheel 9. It shall be noted that, when the wedge 11 is released, it is displaced sideways
by the product 100 that moves toward the opening 3. Once the dispensing operation
has been completed, elastic means 22 return the wedge 11 to the central position.
[0047] It shall be noted that each abutment area 18 is defined on a respective projection
10, in particular at the first portion 10a. The wheels 9 are oriented such that their
first portions 10a are offset by 180°.
[0048] Particularly referring to figure 6, it shall be noted that, according to the present
invention, multiple devices 1 may be integrated in a single drawer 50 for product
dispensing machines. Advantageously, the modularity of the device 1 allows devices
for different products, possibly having different sizes, to be integrated in a single
solution. It shall be noted that, by this arrangement, the side walls 4 of the storage
compartments 2 of two devices 1 are adjacently shared, i.e. is belong to both devices
1.
[0049] The device 1 operates as follows. The dispensing means 7 are actuated, and namely
their wheels 9 are rotated in the direction of rotation "R", namely through 180°,
to dispense the product 100 that is closest to the opening 3. This will cause the
projection 10 associated with the product 100 being dispensed to emerge from the slot
17, and abut the product 100, thereby feeding the latter toward the opening 3. At
the same time, the rotation of the other wheel 9 moves the abutment area 18 away from
the wedge 11, thereby allowing the product 100 to pass by pushing it sideways. Hence,
the product 100 is pushed out of the opening 3.
[0050] Once the product has been dispensed, the feeding means 19 are actuated, namely by
moving the movable wall 20 forward toward the opening 3. By this arrangement, the
first product of the other row 101 will be moved in front of the opening 3, and be
ready to be dispensed.
