Description

CURRENCY DISPENSER

Field of the Invention

The present invention relates to a dispenser

of coins, designed to be used to deliver

5

unit coins in applications such as machines

automatic vending, recreational, collection

parking lots, etc.

The dispenser of the invention is of the type of

comprising a coin store and a unit extractor

1 o

of coins.

More specifically the dispenser of the invention

It is of the type whose extractor consists of a housing

which defines a cylindrical chamber with lateral outlet, in the

that houses a rotating drive disc that limits by a

fifteen

side the coin store and has a number of

cavities that are closed, on the opposite side to the occupied

for the coin store, for a support base. The

cavities house and drag the coins and dispose in the

wall, from the edge facing the support base, of

twenty

a recess that delimits with said base a passage

facing the side outlet of the cylindrical chamber, for

The output of the coins.

Background of the invention

They are already known coin dispensers

25

used as coin return machines in

change, recreational, vending, etc.

EP 1717762 Bl, EP 1968018 A2, WO

2004/114228 Al, and US 05074824 describe mechanisms of

return of coins based on a rotating disk in which

30 coins are transported to the exit, thanks to the action of a rotating disk with a special geometry and a stop or trigger. This type of device is suitable for extracting different currencies but with the limitation that the cavities must have an adequate geometry to extract the

35 coin of greater diameter and / or of greater thickness, and at the same time two coins of small diameter and / or thickness cannot be extracted. This limitation means that this coin dispenser must be modified depending on the range of coins of greater and lesser diameter and the desired thickness, in some cases the compatibility of coins of different diameters and / or thicknesses with the same extraction disk is impossible.

EP 1717762 Bl, describes a coin extraction system that uses a fixed stop or trigger and a mobile one. This system has the peculiarity that the distance between the fixed stop and the moving trigger must be regulated for each coin range, different systems being necessary for each coin range.

In the mechanism described in EP 1968018 A2 and WO 2004/114228 Al, the coin extraction system uses a mobile trigger, consisting of one or two pieces, and a fixed adjustable plate, responsible for ejecting the coins. This system has a lower complexity than other trigger systems, but it still has the limitation of the coin ranges, it being necessary to define a mobile trigger system and adjustment plate for different coin ranges.

Finally, document EP O95 943 7 Bl, describes a coin dispenser, based on a rotating disc as described above, in which two rotating discs are superimposed, and the diameter of accepted coins can be adjusted by offsetting a disc with respect to the disc other. This device has better behavior regarding quantity

from

discs used for the extraction  from coins, but

keep presenting

limitations from rank.

Description of

the invention

The

Present invention have by object a

coin dispenser that provides unitary delivery of coins efficiently and prevents

drawbacks of the systems known to the state of the art. An object of the invention is to solve the exposed problems, by means of a coin dispenser, of the

initially indicated type, which manages to work reliably

with a wide range of coins, both in diameter and in

thickness.

Another object of the invention is to develop a

5

coin dispenser that is of simple construction and

robust, which also facilitates its use in

applications that require low cost and high reliability,

as is the case for example of vending machines,

recreational or random machines, etc.

10

Starting from the general constitution commented, the

dispenser of the invention is characterized in that of the

surface of the support base facing the disk of

drag protrudes a stop that is opposite the direction of

disk spin This stop radially crosses the path

fifteen

circular of the drive disc cavities and is of

height equal to or less than the thickness of the coin of less

allowable thickness The commented cap is scrollable according to a

concentric circular path with the drive disc

between an advanced position, in which it faces the

twenty

lateral outlet of the cylindrical chamber, limiting the length

of said outlet to a dimension smaller than the diameter of the

coin of smaller admissible size, and a delayed position,

in which it is located immediately behind the

side outlet, according to the direction of rotation of the disc

25

drag The commented cap is constantly driven

towards the advanced position by means of a spring.

According to another feature of the invention, the

drag disc is carrier, for each cavity, of a

retractable part that partially protrudes from the surface

3 o

rear of the disc intercepting the cutout that limits

with the base of support the passage for the exit of coins of

The cavity. In addition, the disc subsequently has a

arched coin-driving wall that is located at

continuation of the retractable part and part in position

35

tangent to said cavity, running towards the periphery of the

   disc, with convexity directed towards the cavity. This

The wall shall be at least equal in height to that of the coin with the highest allowable thickness. With the constitution described, each of the cavities for the accommodation of coins is defined by

5 the corresponding hollow or emptying of the drive disk and the retractable part which, together with the geometry of the drive disk, form the circular cavity housing of the coins. These cavities shall be of equal diameter to that of the coin with the largest admissible diameter, being

10 this diameter of the cavity smaller than the sum of the diameters of two coins of the minimum allowed diameter, so that two coins of the smallest allowed diameter cannot be accommodated on the basis of each cavity. In addition, the retractable parts have a path, perpendicular to the disk of

15 drag, slightly larger than the thickness of the coin with the highest allowable thickness. In this way it is possible to increase the range of coins, both in diameter and thickness, which can be issued one at a time, with the same dispensing device.

20 The support base from which the stop mentioned above protrudes can be constituted by a base disk disposed between the bottom of the cylindrical chamber and the drive disk, concentric with said disk. The commented base disk can be rotatable together with the drag disk

2 5 between the positions mentioned above advanced and delayed the top. The stop may consist of one or more projections protruding from the base disk, in radial alignment thereon. According to an execution variant, the base disk

30 can be fixed and provided with concentric arcuate grooves and angular amplitude at least equal to the displacement that the stop may suffer between its advanced and delayed positions. The stops will consist of teeth that are located below the base disk, aligned

35 radially with respect to said disk, in number and position coinciding with the arcuate grooves of the base disk. These

Teeth protrude through the slots at a height equal to or less than the thickness of the coins of the lowest allowable thickness. In addition, the teeth will be movable along the grooves between the advanced and delayed positions of the stop.

In the rest position of the projections or teeth, in the aforementioned embodiments, these are located so that they partially intercept the lateral outlet of the cylindrical chamber in which the drag disk is housed, leaving a passage section that is smaller than the diameter of the smallest allowable coin.

All the exposed and other characteristics of the invention, as well as the mode of operation of the dispenser of the invention, will be explained in greater detail in the embodiment shown in the attached drawings. Brief description of the drawings

Figure 1 shows a coin dispenser constituted according to the invention, which is comprised of a coin store 1, with a loading port 2, and

a

extractor from coins 3 that understands a Case 4 to the

that

be set the warehouse one.

According to

may appreciate in the figures 2 Y 3, the

Case

4 define a camera cylindrical 5 that has from a

side outlet for the coins, as will be explained below, and in which a drive disc 7 is housed that limits the storage area l.

Additionally, other components not shown are mounted on the housing 4, such as a geared motor for driving the drive disk 7, output detectors and coin levels, electronic control, etc., not shown and all of them of known arrangement.

The drive disk 7 has circumferentially distributed cylindrical cavities, which are closed, on the opposite side to that occupied by the coin store 1, by a support base which in the example shown is configured in the form of a base disk 9 , disposed between the bottom of the cylindrical chamber 5 and the drive disc 7. The cavities 8 will be of sufficient depth to accommodate two or more overlapping coins and of diameter at least equal to that of the coin of greatest admissible dimension, but less than twice the diameter of the coin with the smallest allowable diameter.

As can be seen in Figures 4 and 5, the

wall that limits the cavities 8 presents, from the edge

facing the base disk 9, a recess 10 that runs

between points 11 and 12, along an arc of amplitude

5

enough to allow the passage of the admissible currency of

larger diameter This arc will be of equal angular amplitude or

greater than 180�. In coincidence with the recess 10 of each

cavity 8 the disc is a carrier of a retractable piece 13

facing the base disk 9 which, as can be seen in

10

Figures 6 to 9, is mounted in a housing 14 of the disk

drag 7, where it is scrollable in direction

perpendicular to said base disk 9 between a position

extracted, figure 8, and a retracted, figure 9. In position

removed the retractable part partially intercepts the

fifteen

recess 10, leaving a section of it free, between

points 11 and 15, figure 4, whose rope is shorter

than the diameter of the coin of smaller admissible diameter.

This retractable piece is driven to the position

extracted by means of a spring 16, figure 8.

2 o

Figures 1 O and 11 show the part

Retractable 13, which has projections 17 that protrude to

through recesses 18 of the housing 14, figures 8 and 9.

In addition, these retractable parts 13 also have

projections 19 supporting on stops 20, figure 7, shaped

2 5

in housings 14 to limit the maximum position

Removing the retractable part 13.

As can be seen in Figures 18, 21 and 23,

between the notch 10 of the drive disc and the disk of

base 9 delimits a passage 21 that remains partially

30

intercepted by retractable piece 13, in position

extracted from it.

From the drag disc 7 protrudes, from the

surface facing the base disk 9 and for each cavity

8, a coin-conducting wall 22 located at

35

continuation of each retractable piece 13, which starts in

   position tangent to said cavity, starting at point 12, and

runs with arched path towards the periphery of the disk of

drag, with convexity directed towards the retractable piece

13. This wall shall be at least equal to the thickness of

the thickest coin allowed.

5

In the example shown the base disk 9, which

It constitutes the support base for the drive disc 7,

it has concentric nerves 9 ', figures 3, 12 and 13, whose

height varies to define stops 23 aligned radially and

oriented in the opposite direction to the rotation of said disk of

1 o

drag, so that these stops will radially cross the

circular trajectory of the cavities 8. The stops 23 will be

of height equal to or less than the thickness of the coin of less

allowable thickness

The base disk 9 is rotatable, along with the

fifteen

drag disc 7, between an advanced position, in which

the stops 23 face the side exit 6 of the

cylindrical chamber 5, intercepting said outlet and limiting

the free length of it to a dimension smaller than the

diameter of the smallest allowable coin, as

twenty

represents with a continuous line in figure 24, and a position

delayed in which the stops 23 ', which are represented with

dashed line, they are located immediately behind

of the side outlet 6, according to the direction of rotation of the disc of

drag 7. The base disk 9 and with it the stops 23, are

25

propelled to the advanced position 23 of figure 24

by means of a spring 24, for example of traction, mounted

between a hitch 25 of the base disk 9, figure 13, and a

hitch 26 of the cylindrical chamber 5. The spring 24 will be of

greater tension than spring 16 responsible for driving the

30

retractable piece towards its removed position.

In the position removed from the retractable piece,

Figure 8, the projections 17 thereof are separated from the

support base defined by the base disk 9 a distance

less than the thickness of the coin of less admissible thickness.

35

In the retracted position, figure 9, the projections 16 do not

   they protrude in the 1O recess, said recess being of

depth at least equal to the thickness of the largest coin

allowable thickness The displacement of the retractable piece

between its positions of maximum extraction and retraction will be�

slightly larger than the thickness of the largest coin

5

allowable thickness

As can be seen in Figures 8 and 9, the

projections 17 of the retractable part 13 are limited by the

side directed towards the corresponding cavity 8, by a

inclined surface 2 8, progressively retracted towards the

1 o

free edge.

With the constitution described, the pieces

Retractable 17 in their extracted position partially close

the recess 10 of the cavities 8 and with it the passage 21,

Figures 18, 21, 22 and 23, leaving between points 11 and 15,

fifteen

Figure 4, a restricted passage 10, which does not allow the passage of

Coins of smaller allowable diameter, thus being

capable of cavities 8 dragging one or more coins 2 9

from the coin store 1, as

depicted in figures 14 and 15, until the disk of

twenty

drag reaches a more advanced position than the one represented

in figure 14, in which coin 2 9 supports against

stops 23 of the base disk 9, similar to how

depicted in figure 17.

The process of extracting coins 29 is

25

Performs in four phases. In a first phase, the disk of

drag 7 collect coins 2 9 from the hopper or warehouse

coins 1, which are positioned in cavities 8 of the

drag disc 7. In this first phase they are only transported

the coins to the exit zone 6, and the pieces

30

Retractable 13 are at all times removed

delimiting the circular cavities 8 for the coins 29.

The second phase of extraction begins when a coin 29

find the highlights 23 of the base disk 9.

projections 23, being of a maximum height equal to the thickness

35

minimum currency allowed, will exert force exclusively

   on a coin 29 which will transmit this force on the

chamfering of the retractable parts 13, causing their displacement perpendicular to the drive disk towards the top of said disk, all thanks to its chamfered geometry 28, figures 8 and 9, to the tension of the spring 16, which drives to the retractable piece 13 towards its extracted position and to the tension of the spring 24-34 that drives the stop 23 towards its advanced position, allowing the coin 29 to pass to the coin extraction zone 6. In a possible embodiment, the spring 24-34 may be of greater tension than the spring 16. Once the retractable part 13 has been retracted, the third phase begins. The stops 23 of the base disk 9 continue to exert force on the coin 29, which is moving along the wall 22. In this phase two simultaneous movements occur, the coin 29 is moving supported on the wall 22 of the drive disk 7, and the base disk 9 is rotating in the same direction of rotation as the drag disk 7. The duration of this phase and the path rotated by the base disk 9 will depend on the size of the coin 29 to be ejected, ending said phase when coin 29 reaches the coin exit zone 6 of chamber 5 of the coin dispenser, then the last phase of coin extraction will begin. In this fourth phase, the coin 29 finds the exit zone 6 of the coin extractor 3 and due to the force exerted on the coin by the base disk 9, the coin 29 tends to exit through said coin outlet 6 ejected at high speed due to the action of spring 24 of the base disk,

he

which tour according the currency goes coming out, in sense

contrary

to the of the disk from drag 7, and drives to the currency

stranded towards exteri

or.

So,

in the figure 14 to twenty be It represents the

solution

to the trouble typical that be presents in the

state-of-the-art dispensers, thanks to the action of the retractable parts 13, of the stops 23 of the base disk 9 and of the coin-supporting wall 22 of the drive disc 7.

Next, it will be described how the

extraction of one in one of the 29 coins, from a phase

initial in which the coins are in cavity 8

of accommodation in an area before the exit zone 6 of

5

the coins, until they are completely ejected.

In the first phase of coin extraction

29, as can be seen in figure 14, coin 29 is

located in cavity 8 in an area other than the zone of

coin output 29. In that position the pieces

1 o

Retractable 13 are fully extended, such as

it can be seen in the detail view in figure 15,

limiting cavities 8.

Figure 21 represents exactly the same

situation described for figure 15, with the difference of

fifteen

that instead of a coin, in the coin cavity of the

drag disc 7, two coins are positioned

superimposed 29 and 29 'of the smallest diameter allowed for said

rank.

In figures 14 and 15 the coin 29 is represented,

twenty

in an area near the coin exit zone 6. In this

position the base disk 9, is still in its

resting position, and coins 29, are not yet

exerting pressure on the retractable parts 13.

Figure 21 represents exactly the same

2 5

situation described for figures 14 and 15, with the

difference that instead of a coin, in cavity 8 to

drag disc coins 7, are positioned

two overlapping 29 and 29 'coins, of the smallest diameter

allowed for that range, on the surface of the disk

3 o

base. You can see how two coins are positioned

smaller diameter allowed for that range when they approach

to the exit zone 6 of coins, at the time before

that the bumpers 23 of the base disk 9 start exercising

force against them.

35

In figures 17 and 18 the coin 29 is represented

   in its second phase of extraction, when the currency is

found in the exit zone 6 coins. In this position

the stops 23) of the base disk 9 are exerting force

against the retractable part 13, on the chamfers 28,

moving it to the retracted position 13 'of Figure 18,

5

letting coin 29 out of the disk of

drag 7.

Once the retractable piece 13 has let the

coin 29, begins the third phase in the expulsion of

coins The coin 29 rests on the wall 22 of the disk of

10

drag 7, as shown in figures 19 and

2O. Simultaneously, the base design 9 driven by the

currency, which is in turn driven by the disk of

drag 7, rotates in the same direction of rotation as the disc of

drag 7, as can be seen in figures 16 to 18.

fifteen

Figures 21 and 22 represent a situation

equivalent to that described for figures 15 and 18, with the

difference that instead of a coin, in cavity 8 to

drag disc coins 7, are positioned

two overlapping 29 and 29 'coins of smaller diameter

2 o

permitted. In the detail view of Figure 22, you can

observe how two coins of the smallest diameter are positioned

allowed, when they are in exit zone 6 of

coins, at the time you highlight them 23 on the disk of

base 9 begin to exert force against it. In the figure

2 5

in detail 22, it can be seen how in the case that in a

same coin cell there are two coins

positioned, will only go to the outer area of the disk

coin drag 7, third phase in the extraction,

saving the retractable piece 13, the most positioned currency

30

next to the ejector disk, since this will be the only one that

interferes with the stops 23 of the base disk 9, because

the height of these stops is calculated so that in no

case is greater than the thickness of the coin of smaller thickness

allowed Therefore, currencies that are not found

35

positioned on the surface of the base disk 9 will not be

   ejected out of the dispenser, thus ensuring

the extraction of the coins one by one, as can be seen in Figure 23.

The fourth phase of extracting a coin 29, occurs when said coin finds the coin exit zone 6. With the extractor disk 7 at rest, the dimension of the coin outlet opening 6 is defined by 9 and the bottom part of the outlet 6, said dimension being smaller than the diameter of the coin with the smallest diameter allowed. In this fourth phase, the coin 29 reaches the exit zone 6 of the coin dispenser. Under these conditions and due to the force exerted on the coin by the base disk 9, the coin 29 tends to exit through the opening created in the coin exit zone 6 of the dispenser, and it is ejected once the ejector disk has rotated enough so that the distance from the stops 23 to the bottom of the outlet 6 allows the coin to exit

29. The expulsion of the coin takes place at high speed due to the action of the spring 24 of the base disk 9 which rotates in the opposite direction to that of the drag disc as the coin 29 goes out, to its resting position, driving the outward currency. Once the coin 29 has been removed, the retractable pieces 13 will return to their resting position fully removed, thanks to the action of the springs 16, as well as the base disk 9, thanks to the action of the return spring 24. In this way the extractor system will be ready to perform the next coin extraction.

In figures 25 to 29 a variant of the base disk 9 of figure 3 is shown. In this variant of execution the base disk, indicated with reference 30, is fixed and has arcuate grooves 31 concentric with said disk and of amplitude angular at least equal to the described displacement of the stops 23 between their advanced and backward positions. The stops are constituted by teeth 32 which, like the stops 23, are radially aligned. These teeth are part of a sector 33 located behind the base disk 30, concentric with said disk and rotatable thereon, together with the drive disk 7, between the advanced and delayed positions of the stops 23, figure

24. Sector 33 is driven towards the advanced position of

5 the teeth 32 by means of the spring 34 and as in the embodiment of figure 3, the tension of this spring 34 is higher than that of the spring 16 of the retractable part 13. The height of the teeth 32 will meet the exposed conditions for stops 23.

10 Moreover, both the functionality and the mode of operation of this system is identical to that described for the base disk 9. The variant of figures 25 to 29 has the advantage that the coins 29 rest against the fixed disk 30

15 and not against the mobile base disk 9, whereby better system behavior is achieved, by decreasing the friction between currency and base disk.
