Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin handling device such as an automatic transfer device or an automatic money changer for promptly and reliably taking in inserted coins into the device.

[0002]

2. Description of the Related Art In recent years, financial institutions such as banks use automatic transaction devices (hereinafter referred to as ATM) to automatically perform withdrawal and deposit of deposits, transfer to other accounts, and exchange operations. Activities are carried out in an effort to reduce the work of the counter and save labor.

In the ATM having a coin processing device, conventionally, a single rotary disk having a conical projection near the center of rotation is provided at the coin inlet.
The coins thrown in from the coin inlet were sequentially drawn out toward the outer edge of the rotating disk by the centrifugal force, and the coins were taken in one by one to be taken in the ATM main body.

[0004]

[Problems to be Solved by the Invention] AT for banking business
In M, when the coins were taken into the main body of the apparatus, the centrifugal force of a single rotating disc having a conical protrusion was used to pay out coins toward the outer edge of the rotating disc and take them in one by one.

In such a rotating disk, the peripheral speed of the rotating disk is increased in order to obtain a sufficient centrifugal force for reliably delivering coins. To increase the peripheral speed of the rotating disk, It is necessary to increase the diameter of the rotating disk or increase the number of rotations. However, in the case of being mounted on an ATM or the like, the coin processing device itself is required to be downsized and narrowed, and the size of the diameter of the rotating disc including the conical projection is also limited.

In addition, in the coin processing device, it is necessary to open a certain distance between coins sequentially dispensed from the rotating disc in order to inspect the coins dispensed to the outer edge of the rotating disc and sort the coins by the gate. is there. For this reason, there is also a method of increasing the transfer speed of coins to open an interval on the transfer path after feeding, but the upper limit of this transfer speed is restricted by the operating speed of the sorting gate. Therefore, the upper limit of the payout speed of the rotary disk, that is, the number of rotations of the rotary disk is also restricted by the restriction of the coin transport speed after the payout.

Therefore, in the vicinity of the center of rotation on the inner side of the rotating disk, the diameter of the rotating disk becomes smaller, so that the peripheral speed becomes smaller, sufficient centrifugal force cannot be obtained, and coins tend to remain. Especially for 1 yen coins that are light in weight, if the surface is wet or the deposits are attached, the coins will stick to the rotating disk and remain on the disk without being pushed out toward the outer edge, which may cause erroneous operation. Was there.

When residual coins on the rotating disk are detected,
The rotating disk rotates forward → stops → until all the coins are paid out
Since the reversing operation must be repeated in the order of reverse rotation → stop → forward rotation, there is a problem that the feeding process takes time and impairs speediness.

In view of the above, the present invention eliminates the above-mentioned problems. Despite the miniaturization of the rotating disk, all the inserted coins can be reliably and quickly paid out without leaving any coins remaining. It is an object of the present invention to provide a coin processing device which improves the reliability of the coin and, in turn, improves the service to users.

It is driven separately.

In order to solve the above problems, the present invention makes the rotation of the inner disk by the above-mentioned first drive means faster than the rotation of the outer disk by the second drive means.

Further, in order to solve the above-mentioned problems, the present invention provides
The inner disc is made of a material having a lower friction coefficient than the outer disc.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in FIGS.

FIG. 1 shows an ATM 10 for automatic transfer and the like.
FIG. 1 is a schematic view showing the external appearance of a touch panel 11, which also functions as a display device and an input device, a card insertion slot 12, a passbook insertion slot 13, and a bill processing device (not shown) for taking bills. The banknote insertion port 14 and the coin processing device 16 are provided with a coin insertion port 17 for taking in coins.

Here, the coin processing device 16 is constructed as shown in FIG. The coin slot 17 is a rotatable saucer 1
7a and a sliding shutter 17 for opening and closing the upper surface thereof
a coin 1 which has b and is dropped from the tray 17a below
A coin feeding unit 20 for feeding 8 coins one by one is provided.

On the bottom surface of the coin feeding portion 20, an inner disk 21 made of stainless steel having a conical projection 21a at the center thereof, and a urethane rubber 22a on a part of the stainless disk concentric with the inner disk 21 are provided. Outer disk stuck 2
A rotating disk 23 composed of 2 and 3 is provided. An annular hopper 24 is provided at the peripheral edge of the outer disk 22 so that the inner peripheral surface thereof receives coins.

Numeral 26 is an opening for taking out the coins 18 one by one in the direction of the coin transport path 27, and is provided with a thickness regulating member 26a for preventing two coins from being taken out. 2 more
Reference numeral 8 denotes an optical sensor, which is a residual detection means including a photodiode 28a and a phototransistor 28b, for detecting residual coins on the rotary disk 23.

On the other hand, the inner disk 21 has a first motor 30c whose rotation speed is variable, a first drive gear 30a, a second drive gear 30b and a first shaft 30d. The outer disk 22 is fixed to the shaft 30d of the first motor 31c and the third drive gear 31.
a, the fourth drive gear 31b, and the second shaft 31d. The second drive means 31 is fixed to the second shaft 31d.

The rotation speed Nb of the second shaft 31d
Is set to a predetermined value by the outer diameter of the outer disk 22 and the peripheral speed Vc for obtaining a sufficient centrifugal force required for feeding coins. However, the peripheral speed Vc of this outer disk 22
The upper limit is regulated so that Vc <V1 <V2, where V1 is the conveying speed of the pickup belt 27a in the coin conveying path 27 and V2 is the conveying speed of the speed increasing belt 27b.

On the other hand, in the inner disk 21 having an outer diameter smaller than that of the outer disk 22, it is necessary to increase the number of rotations in order to obtain a sufficient centrifugal force equivalent to that of the outer disk 22. Since the peripheral speed of 21 is not restricted by the operating speed of the gate described later, that is, the conveying speed V2 of the speed increasing belt 27b, the rotation speed Na of the first shaft 30d is sufficient for the coin 18 on the inner disk 21. It is set to be higher than the rotation speed Nb of the first shaft 31d so that the rotation speed gives a centrifugal force.

Next, reference numeral 32 denotes a coin inspection section provided on the speed increasing belt 27b for detecting the denomination of the coin 18 from the material and size thereof, and 33a to 33f correspond to the detection result of the coin inspection section 32. The first to sixth gates are opened and closed and are provided at the entrances of the first to sixth temporary holding units 34a to 34f. 36 and 37 are first and second return conveyor belts for returning the inserted coins 18. Further, 38 is a recovery gate for recovering coins that cannot be detected by the coin inspection section 32, and 39 is a return gate for returning coins missed at each gate. The undetectable substances recovered by the recovery gate 38 are returned to the first return belt 36 via the recovery path 40 or are recovered on the recovery belt 41a of the safe 41, and the return gate 39 is used. The coins taken in are returned to the coin slot 17 by the first and second return conveyor belts 36 and 37.

Further, 38 is a gate for inserting the coin 18 into the temporary holding section 40 when the first to sixth safes 42a to 42f for storing the inserted coins 18 are full. From the temporary holding unit 40, it is stored in the safe 41. Reference numeral 39 is a return gate for recovering coins that cannot be detected by the public inspection unit 32 and for returning coins missed at each gate. The recovered undetectable material is returned to the inlet 17 via the first and second return conveyor belts 36 and 37.

Further, 42a to 42f are temporary holding units 34a to 34a.
First to sixth safes for storing coins 18 from 34f, 43 is safes 42a to 42f or recovery belt 41.
It is a storage belt that conveys the coins 18 and undetectable objects from a to the storage unit 44.

Next, the operation of the coin feeding section 20 will be described. The coins 18 inserted from the coin slot 17 are
When the coin 18 is dropped from the saucer 17a to the coin feeding portion 20, the coin 18 slides down the conical protrusion 21a, and the coin 21 moves.
Alternatively, it is placed on the outer disk 22. As a result, the first and second motors 30c and 31c start driving, the inner disk 21 is rotated at the rotation speed Na, and the outer disk 22 is rotated at the rotation speed Nb. Then, the coin 18 sequentially reaches the peripheral edge of the outer disc 22 by the rotation of the inner disc 21 and the outer disc 22, and is fed out from the opening 26 to the coin transport path 27 side by the pickup belt 27a.

Although the inner disc 21 has a smaller outer diameter than the outer disc 22, the rotational speed Na is sufficiently large, so that a sufficient centrifugal force is applied to the coin 18 on the inner disc 21. , Will not be left behind. However, if a residual coin is generated and the residual coin is detected by the optical sensor 28, the first motor 30c is controlled by the control device (not shown).
The residual coins are delivered by controlling the driving of the coins, for example, further increasing the rotation speed, or temporarily stopping and then reversing the balance to break the balance between the centrifugal force and the frictional force acting on the coins 18. .

The coins dispensed from the coin dispenser 20 in this manner are conveyed by the pickup belt 27a and the speed-increasing belt 27b, and the coin inspection unit 32 and each gate 33a.
Through 33f, the data is held in the temporary holding units 34a to 34f. Then, when a match between the input amount and the check amount is input from the touch panel 11, the temporary holding units 34a to 34f.
It will be stored in the safes 42a to 42f.

According to this structure, the rotary disk 23 is divided into the inner disk 21 and the outer disk 22, and the rotation speed of the outer disk 22 depends on the operating speed of the gates 33a to 33f. Gates 33a-33
Since the upper limit of the rotation speed is not restricted in the inner disk 21 that is not restricted by the operation speed of f, the centrifugal force required to pay out the coin 18 can be easily obtained by increasing the rotation speed. , Coin 18 does not remain. Even if residual coins are generated, no restrictions are imposed when controlling the operation of the inner disk 21, so that the rotational speed can be increased or reversed freely.
Residual coins can be easily dispensed, and coins can be processed more quickly and accurately.

The present invention is not limited to the above-mentioned embodiment, but can be modified within the scope of the invention, and the material and shape of the inner disk and the outer disk are arbitrary, for example, the inner disk. In this case, in order to further reduce the coefficient of friction, the surface may be provided with irregularities, and the outer disk may not be attached with urethane rubber or the like. Further, the first and second driving means for driving the inner disc and the outer disc may be combined with a drive motor by changing the clutch and the gear ratio.

Further, the inner disc and the outer disc may be arbitrarily rotated. For example, the inner disc and the outer disc are normally rotated at a constant speed, and the inner disc is rotated at a high speed only when the residual coin is detected by the residual detecting means. You may choose to

[0032]

As described above, according to the present invention, even a small rotating disk can be divided into an inner disk and an outer disk and can be driven individually, so that the outer disk rotates. Despite being regulated in number, the inner disc can freely set the rotation speed, and by increasing the rotation speed due to its small outer diameter, it is possible to give a sufficient centrifugal force even for a light coin, Coins can be quickly and reliably fed out without generating residual coins, and the reliability of the device is improved. Even if residual coins are generated, the inner disc can be driven freely for feeding out the residual coins, so it is possible to dispense residual coins extremely easily and quickly compared to the conventional integrated rotary disc, and speed up the coin processing. It can be upgraded and the service to customers is improved.
