[0001] The invention relates to a popcorn vending machine of an improved type.
[0002] Popcorn vending machines are known which are installed especially in meeting places
such as cinemas, game arcades, exhibition spaces, sports facilities and the like.
[0003] These known machines generally comprise a tank for containing grains of corn, a dosage
device for selecting the quantity of corn to be introduced in roasting means, and
means for dispensing the corn that has been roasted and converted into popcorn toward
suitable mixing means, where the popcorn receives the addition of flavoring substances.
[0004] These flavoring substances are constituted, preferably but not exclusively, by salt
or sugar and are contained in appropriately provided tanks, from which they are sent
to the mixing means by way of the selection and dosage devices.
[0005] After mixing, the salted or sugared or otherwise flavored corn is poured by dispensing
means into a container that can be removed manually by the consumer.
[0006] These known vending machines, however, have a series of acknowledged drawbacks.
[0007] A first drawback relates to the problems that they have regarding the management
of the flavoring substances, which are highly hygroscopic, such as sugar and salt.
[0008] These substances in fact tend to agglomerate in lumps inside the corresponding tanks;
if such lumps assume excessively large dimensions, they can block the dispensing ducts
or not pass through them.
[0009] Accordingly, the dosage of the substance is imprecise or nil, with the consequence
that the product is supplied to the consumer without the expected dose of flavoring
substance.
[0010] This of course entails the need, on the part of the operator, to act with accurate
maintenance in order to restore the correct operation of the vending machine.
[0011] It is evident that the problems that these machines have in management especially
of the sugar and salt due to the problem mentioned above also entail the need to perform
frequent preventive maintenance if one wishes to avoid or at least reduce the described
malfunctions.
[0012] A further drawback relates to the aggressiveness, especially of salt, with respect
to some of the elements that compose the vending machine and with which they come
into contact during operation.
[0013] This entails the need to use special materials that entail an increase in manufacturing
costs.
[0014] A further drawback relates to the complexity of these vending machines especially
when the number of flavoring substances to be managed is large.
[0015] It is in fact necessary to provide for each one of them a chute in order to make
each one of such substances flow and gather toward the mixing chamber.
[0016] In order to obviate the mentioned drawbacks, the popcorn vending machine according
to
EP 1 887 533 has been provided in which the dosage of the popcorn flavorings occurs without such
flavorings affecting the correct and regular operation of the machine.
[0017] Moreover, this machine requires less maintenance than known machines, since the flavoring
substances do not come into contact with parts of the machine.
[0018] For this purpose, the vending machine comprises a lid dispenser for closing the containers
into which the popcorn is poured, wherein each lid is provided with a chamber for
containing the flavoring substance.
[0019] The containment chamber is delimited by a film that can be broken by pressing and
is directed toward the inside of the container when the lid is applied to the container.
[0020] Therefore, once filling has occurred, the user takes the container with the popcorn,
associates the lid with it and, by means of pressure applied thereon, breaks the breakable
film, making the flavoring substance fall into the container.
[0021] Shaking of the container on the part of the user entails the mixing of the flavoring
substance with the popcorn prior to consumption.
[0022] The vending machine according to the cited patent, however, also has, together with
the advantage of absolutely not having to manage the dosage of the flavoring substances,
the acknowledged drawback of having to take the container manually from a dispenser
and equally manually placing it at the dispensing means for filling.
[0023] Moreover, another drawback is that the dispenser is arranged outside the machine
and is therefore exposed to vandalism on the part of ill-intentioned individuals.
[0024] The aim of the present invention is to eliminate the above noted drawbacks, by providing
a popcorn vending machine that does not require handling of the container on the part
of the user during preparation and dispensing of the product but only the removal
of the container once dispensing of the product has occurred.
[0025] Within this aim, an object of the machine according to the invention is to allow
better protection of the containers.
[0026] Another object of the machine according to the invention is to have such characteristics
as to make it less vulnerable to vandalism on the part of ill-intentioned individuals.
[0027] This aim and these and other objects which will become better apparent hereinafter
are achieved by a popcorn vending machine, which has the characteristics described
in claim 1, to which reference is made for the sake of simplicity in description.
[0028] Further characteristics and advantages of the machine according to the invention
are described in the dependent claims.
[0029] According to the preferred embodiment described here, the machine comprises an enclosure
constituted by a box-like body which accommodates internally the means for containing
the lids, the means for containing the containers, the means for gripping and transporting
each individual lid to the pick-up position at the disposal of a user, and the means
for transferring the container to move it from the vending machine to the pick-up
region, where filling occurs.
[0030] Advantageously, the presence of all the listed elements makes the operation of the
machine completely automatic, so that the user is only required to insert the amount
that corresponds to the cost of the product and to pick up the container and the lid
once dispensing has occurred.
[0031] Also advantageously, the machine according to the invention is therefore simpler
to use than known machines.
[0032] Even more advantageously, the containment of all the elements of the machine within
the box-like body increases the degree of hygiene of the vending process and also
constitutes a deterrent for any vandalism on the part of ill-intentioned individuals.
[0033] The aim, the objects and the advantages listed will become better apparent from the
following detailed description of a preferred, but not exclusive embodiment of the
invention, illustrated by way of non-limiting example in the accompanying drawings,
wherein:
Figure 1 is a general perspective view of a machine according to the invention;
Figure 2 is a sectional side view of the machine of Figure 1;
Figure 3 is a sectional rear view of the machine of Figure 1;
Figures 4 to 8 are a corresponding number of perspective views of the internal part
of the machine according to the invention in different steps of dispensing;
Figures 9 to 11 are views of details of the machine according to the invention.
[0034] With reference to the Figures, a popcorn vending machine according to the invention
is generally designated by the reference numeral 1.
[0035] As can be seen preferably in Figures 2 to 8, the machine 1 comprises a box-like body
2, which is visible in particular in Figure 1, and contains internally a tank 3 for
corn grains, a dosage device 4 for selecting the quantity of corn to be introduced
in roasting means 5 to be converted into popcorn, and dispensing means 6 for transferring
the prepared popcorn into a container 7 that can be removed manually by a consumer.
[0036] As can be seen, the dispensing means 6 comprise an accumulation vessel 8, which is
connected in input to means 9 for transferring the prepared popcorn into the roasting
means 5; such vessel is provided in output with an inclined plane 10, which is directed
toward the corresponding container 7 that is provided in a region 11 for picking up
the containers 7 after they have been filled with the popcorn.
[0037] In the front part of the dispensing means 6 there is a dispenser 12 of containers
7 and in the lower part of the box-like body 2 there is a dispenser 13 of lids 15,
which is provided with means 14 for gripping and conveying each lid 15 into a pickup
region 16 at the user's disposal.
[0038] As regards the lids 15, each one is of the per se known type, and as can be seen
in Figure 10, is provided with a chamber 15a for containing the flavoring substance,
which is delimited by a film 15b that can be broken by pressing and is directed toward
the inside of the container 7, when the lid is applied to the container 7. The lid
dispenser 13 comprises containment means 17, which are arranged mutually side-by-side,
for at least two stacks 18a, 18b of lids 15 and means 20 for lifting each one of the
stacks 18a, 18b toward the grip and conveyance means 14, which are arranged in the
upper part of such stacks of lids.
[0039] In particular, the lifting means 20, which are visible in detail also in Figure 10,
comprise two lifting pans 21a, 21b, each of which supports one of the stacks of lids
18a, 18b and is coupled to a transmission belt 22, which is wound in a closed loop
between two pulleys 23, 24, which are aligned along a vertical axis Y, which defines
the vertical lifting direction Y of the lifting pans 21a, 21b, designated by the arrow
25.
[0040] One of the pulleys is turned by first motor drive means constituted by an electric
motor 26.
[0041] As regards in particular the grip and conveyance means 14, they comprise a clamp
device 27, which is visible in detail in Figure 11, and is associated with translational
motion means 28 arranged above the stacks of lids 18a, 18b, which define a horizontal
direction of translational motion X of the lifting pans 21a, 21b.
[0042] In particular, the clamp device 27 comprises two mutually opposite grip elements
40, which can slide along guiding bars 42 elastically by contrast with springs 43
which are coaxial to the guiding bars 42.
[0043] Each grip element 40 is provided with a pair of protruding pins 41 for contrast and
grip of the lids 15.
[0044] The translational motion means 28 comprise a transmission belt 29, which is wound
in a closed loop between two pulleys 30, 31 which are aligned along the horizontal
direction of translational motion X of the grip and conveyance means 14.
[0045] One of the pulleys, and in particular the pulley designated by the reference numeral
30, is turned by second motor drive means constituted by an electric motor 32.
[0046] As regards the motor drive means, which in the described embodiment are constituted
by electric motors, respectively the electric motor 26a for lifting the lifting pans
21a, 21b and the electric motor 32a for the translational motion of the grip and conveyance
means 14, they can be of any type, for example of the step type or brushless type
and the like.
[0047] Moreover, they are managed by an electronic central control unit, which controls
and monitors their operation and also the operation of the additional elements that
compose the machine.
[0048] According to the invention, there are means 33 for transferring each one of the containers
7, which arrive from the dispenser 12 of containers, toward a region 34 for picking
up the container 7 that can be accessed by a user.
[0049] The transfer means 33, as can be seen also in detail in Figure 5, comprise a contoured
bracket 35, which is arranged in contact with the container 7 and is associated with
the grip and conveyance means 14 of each one of the lids 15.
[0050] In particular, it is also noted that the contoured bracket 35 has a concave region
36 whose profile 36a can be mated with the outer lateral surface 7a of the container
7.
[0051] Functionally, the cycle for preparing and dispensing popcorn begins with the machine
arranged in the configuration shown in Figure 4, after the user has inserted the required
amount in a slot 1a provided on the front of the machine that can be seen in Figure
1.
[0052] The cycle begins after the user has selected the type of popcorn that he/she intends
to consume, therefore salted or sugared, by means of one of the buttons 1b arranged
on the machine front that can be seen in Figure 1.
[0053] It is evident that even more than two selections may be possible, depending on the
types of flavoring product that are present in the lids and on the number of stacks
of lids installed in the machine.
[0054] The first operation of the cycle provides for picking up one lid 15 by means of the
clamp device 27 of the grip and conveyance means 14, which, as can be seen in Figure
6, lift it so as to separate it from the respective stack.
[0055] Simultaneously, a container descends by gravity from the dispenser 12 of the containers
7 and arranges itself, as can be seen in Figure 6, at the transfer means 33 and particularly
at the contoured bracket 35 that is associated with the grip and conveyance means
14 of the lid 15.
[0056] Then the translational motion of the grip and conveyance means 14 with the lid 15
and the container 7 aggregated therewith occurs in the horizontal direction of translational
motion X and ends when the container 7 is present in the pickup region 34 of the containers
7, as can be seen in Figure 7, and the lid 15 is arranged above a pickup region 38
of the lids 15.
[0057] In this position, the container 7 is arranged below the inclined plane 10 of the
dispensing means 6 in a position adapted to receive filling with popcorn.
[0058] The cycle ends when the machine is arranged in the configuration that can be seen
in Figure 8, in which the container 7 is filled with popcorn and the lid 15 is released
in the pickup region 38 of the lids 15.
[0059] The container 7 and the lid 15 therefore can be both picked up by the user.
[0060] Consumption of the popcorn occurs after applying the lid 15 to the container 7 and
breaking the film 15b that delimits the chamber 15a for containing the salt or sugar.
[0061] On the basis of what has been said, it is therefore understood that the popcorn vending
machine according to the invention achieves the intended aim and objects.
[0062] First of all, the presence of the transfer means 33 allows to arrange the container
7 in the pickup region 34 of the containers 7 at the dispensing means 6 of the popcorn
automatically without user intervention.
[0063] In this manner, greater hygiene of the process is also ensured.
[0064] Further, the arrangement inside the machine of the dispenser 12 of the containers
7 and of all the other elements limits the possibility of damage due to vandalism.
[0065] It is evident that during production the vending machine according to the invention
can also be provided with shapes that are different from the ones described above.
[0066] In particular, all the mechanical or electromechanical devices that compose the functional
assemblies of the machine may be provided in any form, even ones which are different
from the ones that are shown and described.
[0067] Finally, the lid dispenser can be structured to receive more than two stacks of lids
so as to be able to flavor the popcorn with more than two substances.
[0068] It is understood that any other variation that is not described and not mentioned
and might be within the scope of the appended claims is to be understood as being
protected by the present patent.
