[0001] The invention is about a mechanism to supply products placed inside containers whose
tops have a protruding rim all the way round forming a lip, a device appliable to
coin-operated vending machines, and containers stacked in set columns in these machines.
[0002] Everybody is familiar with the vending machines located in public places, commercial
outlets and many other public service centres; these machines store certain kinds
of goods which the consumer can obtain simply by placing the coins which will operate
the internal mechanism of the machine, so that it will release the item. Of these
machines we can mention cigarette vending machines, drinks, packets of coins as change
for banknotes, and many others which we shall not mention at the moment.
[0003] Nevertheless, although there are different kinds of vending machines, which dispense
different kinds of items or products, it is also true that these machines are not
designed to dispense products inside containers whose tops have a protruding rim or
lip, this container could keep any kind of product, food items, goods or small articles,
etc., in order to enable the sale of any product or article kept in the above mentioned
type of container.
[0004] To summarize we can say that there are no vending machines designed to fill the gap
that exists because many small products and/or products cannot be obtained by the
consumer anytime anywhere.
[0005] The mechanism of the invention has been devised for this. The said mechanism is appliable
to conventional coin-operated vending machines, and its aim is for the machine to
supply or dispense products kept in a container whose top has a protruding rim, so
that these containers are stacked up in piles or columns which are set up inside the
machine, so that by introducing the right coins, they will activate conventional devices
such as electromagnets or such like, which activate the mechanism of the invention,
thus dispensing the container and, therefore, the product or item inside it, in the
same way as, for example, with cigarette or drink vending machines.
[0006] To be more precise, the mechanism being announced has two pairs of triggers set at
the corners of the front rim of the container, taking it to have a back rim, a front
rim and two side rims. These pairs of triggers are mounted in their respective axles
which are activated via their respective levers. These levers are swung through respective
"U" shape profiles which, linked to a frame, are activated via a lever which in turn
is activated through the internal mechanism (electromagnet or similar) of the machine,
when this mechanism is activated by coins.
[0007] Each pair of trigger is devised so that one of the triggers is set at a higher level
than the other one, and they are also out of phase in angle. This design permits when
these triggers are made to rotate around their mounting axle - a rotation which is
only in part and reversible,- that, while one trigger is ho the containers, the other
one is releasing or free from the containers, so that the said rotation forces the
release of the lower container by the respective trigger, making the other trigger
place itself under the next container, thus holding the stacked up pile of containers
in that column. Therefore, the triggers act alternatively each time they are activated,
always holding the containers by resting the protruding lip on one or other of the
two triggers of each pair.
[0008] Naturally, the mechanism is aided, although independently, by the positioning and
alignment profiles of the containers, so that they can be properly ejected without
any problem.
[0009] To provide an easier understanding of the characteristics of the invention, a detailed
description based on a set of plans will be made and attachached to the present description
as an integral part of it whereby in a merely orientative and not limitative way
the following has been shown.
In fig. 1 can be seen a front view of a vending machine that has the device of the
invention, although it cannot be seen. In this vending machine you can see the containers
to be dispensed in stacks forming columns.
In fig. 2 we show a diagram of the cross section II-II in fig. 1.
In fig. 3 we show a front view of the device.
In fig. 4 we show a front view of the side of a column of containers, with the device
of the invention.
In fig. 5, we show a detail of one of the pairs of triggers in the retaining position
of the containers, viewed from a position as per indicated by arrow "A" in fig. 4.
In fig. 6 we show a front view of the side of a column of containers with the retaining
mechanism in the release position for the containers.
Finally, in fig. 7 we show a detail of the retaining triggers in position of releasing
the bottom container and retaining the rest of the column. This detail corresponds
to the view in the direction indicated by arrow B in fig. 6.
[0010] As these figures show, and especially fig. 1, the s device is appliable to coin -operated
vending machines (1), inside which the containers (2) are stacked up in columns,
with some front plates (3) which can be tilted, allowing the loading of the containers
(2) in the machine.
[0011] The containers (2) have a protruding rim (4) through which the stacked up packets
are retained, until the supply mechanism comes into operation.
[0012] The said containers (2) are stacked up between a back plate (5) of the vending machine
(1) and some tubular side profiles (6); these profiles are fixed to supporting beams
(7). In front of the back plate (5) an omega profile (8) has been devised to mark
the back position of that column of containers (2), as well as a small positioning
ramp (9) for the bottom container of the column of containers, forcing this bottom
container into the right position to be dispensed easily, all of this in such a way
that in front of the lower part of the said ramp (9) a horizontal profile (10) has
been devised to hold the back of the container (2) by the lip (4), ready to be dispensed.
This profile (10) also supports the beams (7).
[0013] As for the device itself, it is made up of two pairs of identical triggers, set up
so that each pair is in an area corresponding to the corners of the containers (2),
as can be seen in fig. 2. Each of the said pairs includes two triggers (11) and (12);
firmly held in a common axle (13); these triggers (11) and (12) are out of phase in
angle and out of phase horizontally with each other, so that trigger (11) is set higher
than trigger (12), while the unit is supported on a horizontal plane (14).
[0014] The mounting axle (13) of each pair of triggers (11) and (12), is extended downwards,
in order to join, individually, to a lever (15) from which a stub (16) comes out which
is set between the side parts of a plane (17) or slotted piece, which is firmly held
to a rotating slotted part (18) to which a lever (19) with its axle (20) is linked.
[0015] With this structuration, when the right coins are introduced in the vending machine
(1), the respective mechanism (electro-magnet or similar) will be activated, and
through it a lever is activated, making it swing abd thus making the slotted part
(18) rotate on the axle (20). The rotation of this slotted part causes the swinging
of the plane (17) or slotted piece, making its internal part butt against the stub
(16) of the lever (15), driving it and, therefore, rotating the axle (13). The said
rotation, which will only be in part, will also cause the rotation of the pair of
triggers (11) and (12), so that trigger (12), which was holding the bottom container
(2) by its lip (4) comes away in this partial rotation and allows the bottom container
(2) to fall; its lowest support on the profile (10) will be freed by gravity and so
the next container will fall in the said plane (10), thus avoiding the need of a second
set of triggers, which would make the whole device rather more complicated. At the
same time, the other trigger (11), will have turned as well and will have placed itself
under the container inmediately above it, so that this container will be the bottom
one when the previously mentioned container falls, being held by the other trigger
(11). So, each time a different trigger acts to hold or support the pile of containers
(2).
[0016] Naturally, the reason for just mentioning one pair of triggers and the parts attached
to it is because the device is repeated on both sides (right and left) and both work
in synchroni, in the same way and simultaneously.
1º.- Device to supply products inside containers with a top which has a protruding
rim forming a lip, which has been devised to be applied in coin-operated vending machines
where the containers will form units piled up in columns properly guided by profiles
which hold the said column of containers, both by the back and by the sides, and which
is mainly characterized because it is made up of two identical pairs of triggers
set in the positions corresponding to the front angle of the container, containers
which have a protruding lip which is supported by one of the two triggers of each
pair, with the peculiarity that these triggers are out of phase in angle and horizontal,
thus one of the triggers is higher than the other one, so that when the former holds
and retains the pile of containers the latter is free from that pile or column, while
the fall of the bottom container causes the other trigger to become of retention of
the column of containers; it has been devised means so that each pair of triggers
is simultaneously activated by the action of a lever which is itself activated by
a conventional mechanism or gadget (electromagnet or silmilar) activated by the introduction
of coins, having intermediate means which link the said lever to the pair of triggers.
2º.- Device to supply products held in containers whose tops have a protruding rim
all the way round forming a lip, as said in claim 10, characterized because the axle
to which the two triggers from each pair are linked, is extended downwards to join
a lever with a stub freely inserted between the two side parts of a "U" shape profile
or slotted piece,which is linked to a rotating part on a rotating axle; it is from
this slotted part that the initial actuation lever stems from.
3º.- Device to supply products held in containers whose tops have a protruding rim
that form a lip, as said in the previous claims, characterized because the back guidance
of the column of containers is done through an omega shape profile, while the sides
are guided through their respective tubular profiles supported on horizontal beams;
a positioning ramp has also been devised to position correctly the bottom container,
before it is ejected, supporting the said bottom container by its lip on a higher
horizontal plane which is also a support for the supporting beams of the tubular profiles
to guide the sides.
