Industrial Applicability The present invention accurately controls the rotation control of a temporary holding unit of a coin processing machine that accepts coins and performs necessary processing such as ticketing processing and payment processing, such as an automatic ticket vending machine or an automatic payment machine. The present invention relates to a temporary holding device of a coin processing machine that can perform the processing.

[0002]

2. Description of the Related Art Conventionally, for example, in an automatic ticket vending machine, coins inserted in the main body of the automatic ticket vending machine are not immediately collected in a change hopper or a safe in the main body, but until one ticket processing for one customer is completed. , The coins inserted by the customer are temporarily stored in a holding section, and the customer is matched with the inserted coins to prevent trouble, or the customer has stopped purchasing the ticket after coin insertion. At times, it is configured so that the inserted coin itself can be returned.

[0003] When collecting coins received in the temporary holding section, the temporary holding section is inverted by a reversible motor in response to a collection command when the ticketing process of one user is completed, and the change hopper or the safe is transferred via the chute. On the other hand, in the case of return, in response to a return command of the cancel button pressed by the customer, the temporary holding unit is reversed in the opposite direction to that at the time of collection and returned to the return port via the chute (for example, Kaisho 64-
No. 46879).

[0004]

However, in the above-mentioned conventional device, the motor is rotated forward or backward based on the collection or return command, and therefore, the coins to be returned unless the motor rotates as instructed are used. There was a risk of being collected inside the body.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a temporary holding device of a coin processing machine which can determine whether the motor is rotating as instructed and can surely control the rotation of a temporary holding unit. I have.

[0006]

In order to achieve the above object, the present invention provides a temporary holding unit which is rotated by a motor before collecting coins inserted into the main body of the coin processor into the main body. In a temporary holding device of a coin processing machine that receives or collects or returns the coins in the temporary holding unit by rotating the motor forward or reverse by a receiving or collecting command or a returning command, around the rotation axis of the temporary holding unit. A first arm, a second arm, and a third arm provided at a predetermined angle; a first detection piece provided on the first arm and having a predetermined width along a rotation direction of the rotation shaft; A second detection piece provided on the second arm and wider than the first detection piece and having a slit on one of the left and right sides in the width direction; and a third detection piece provided on the third arm. , The temporary holding section is before The first sensor and the second detecting respectively a substantially central portion of the width direction of the second detection piece and the first detection piece in place when accepting coins put into the body
If the detection pattern when the first sensor and the second sensor respectively detect the first detection piece and the second detection piece at the time of the collection command is a predetermined pattern, the motor rotates normally in the collection direction. Determining means for determining that the motor is normally rotating in the return direction if the detection pattern is a predetermined pattern different from the predetermined pattern at the time of the return command,

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of an apparatus according to an embodiment.
Is a stepping motor (motor) and 1 is a temporary holding section (temporary holding cylinder), which is provided on the frame A of the main body (not shown). Of these, the temporary holding section 1 has 5
There are cylinders 2a to 2d for storing coins of 0 yen, 500 yen, 100 yen, and 10 yen, and rotating shaft shelves 3a and 3b provided on the left and right sides are supported by the frame A.

Gears 4 and 5 are provided on the rotating shaft 3a on the motor M side and the rotating shaft of the motor M, respectively, and a timing belt 6 is stretched between these gears. Therefore, when the motor M rotates, the temporary holding unit 1 also rotates with the rotation.

A detection plate 7 is fixed to the rotating shaft 3a as shown in FIG. The detection plate 7 has a first arm 7a radially extending at an interval of 120 ° from the rotation shaft 3a, and a second arm 7a.
It has three arms, an arm 7b and a third arm 7c, and a first detection piece 8a, a second detection piece 8b, and a third detection piece 8c are provided at the ends of these arms at right angles.

The planar shapes of the detection pieces 8a to 8c are shown in FIGS. 2 (a) to 2 (c). That is, the first detection piece is a small piece located at the center of the first arm,
The width of the second detection piece is wider than that of the first detection piece 8a and is equal to the width of the second arm 7b, and a slit 9 is provided on the left side. The third detection piece 8c is provided on the right side of the third detection piece 7c. In addition, the x mark in the first detection piece 8a and the second detection piece 8b indicates a fixed position (home position) when the temporary holding unit 1 receives a coin inserted into the main body.
2 shows detection positions of a first sensor and a second sensor described later.

First sensor PH1 (hereinafter referred to as PH1)
The second sensor PH2 (hereinafter, referred to as PH2) has a detection element formed of a photocoupler at a U-shaped tip, and the above-described detection pieces 8a to 8c can pass through the U-shaped part. Further, it is provided on the frame F while maintaining the arrangement relation at the fixed position as described above.

In the figure, C is a controller (judgment means, rotation control means) which is constituted by a microcomputer and which inputs a recovery command or a return command and detection signals from PH1 and PH2 to rotate the motor M forward. Or with reverse rotation drive,
The main body 1 is generally controlled.

Next, the control operation of the apparatus of this embodiment will be described with reference to the time chart of PH1 and PH2 in FIG. First, the recovery rotation in which the escrow unit 1 rotates clockwise will be described first.

Now, assuming that a recovery command is given to the controller C, the motor M starts rotating clockwise. By this rotation, PH1 is turned on when the shielding of the first detection piece 8a is released, and PH2 is turned on with the slit 9 positioned.
When the rotation is further continued, PH1 remains ON, but PH2 is again shielded by the second detection piece 8b and OF
It becomes F. In the case of such a detection pattern of PH1 and PH2, it is stored in the memory of the controller C that the rotation is a normal recovery rotation. Therefore, the detection pattern is compared with the pattern in the memory, and the rotation is normal. Is determined.

If the recovery rotation is determined to be normal, the motor M
Is further continued, and PH1 becomes O at the third detection piece 8c.
It is continued until it is set to FF. PH1 is the third detection piece 8c
Is detected, the inclination of the temporary holding unit 1 is sufficient to discharge the coins therein, and the coins in the temporary holding unit 1 are collected by a change hopper (or safe) via a chute (not shown). .

By the way, when the detection patterns detected at PH1 and PH2 are different from those described above, that is, when PH2 is not turned on or off despite PH1 being turned on, the rotation of the temporary holding unit 1 is normal. Since it is not the recovery rotation, the motor is stopped and both PH1 and PH2 are turned off.
The rotation is reversed until the original position becomes F, and the collection rotation operation is started again.

When a return command is input to the controller C,
That is, when the cancel button provided on the main body is pressed by the user or when the return button is pressed by the attendant, the motor M starts rotating in the counterclockwise direction. By this rotation, PH1 is turned on after the shielding of the first detection piece 8a is released, and PH2 is turned on slightly after the turning on of PH1. When such a detection pattern of PH1 and PH2 is stored in the memory of the controller C as a normal return rotation, the detection pattern is compared with the pattern in the memory and the rotation is normal. Is determined.

If the return rotation is determined to be normal, the motor M
Is further continued, and PH2 becomes O at the third detection piece 8c.
It is continued until it is set to FF. PH2 is the third detection piece 8c
Is detected, the inclination of the escrow unit 1 becomes sufficient to release the coins therein, and the coins in the escrow unit 1 are returned to the return port via a chute (not shown).

When the detection patterns detected at PH1 and PH2 are different from those described above, for example, PH1 is turned on.
When PH2 is turned on at the same time as the above, the rotation of the temporary holding unit 1 is not a normal return rotation, so the motor is stopped, and the motor is reversed until it returns to the original position where both PH1 and PH2 are turned off. The return rotation operation is started.

As described above, the apparatus of this embodiment determines whether the rotation of the temporary holding section 1 is normally performed at the beginning of rotation.
The detection pattern detected at PH1 and PH2 is compared with the pattern stored in the controller C to make a determination. Only when the determination is correct, the temporary holding unit 1 is rotated to a predetermined collection position or a return position. Therefore, it is possible to prevent a malfunction of the temporary holding unit 1 before it occurs.

In the above-described embodiment, the motor M and the rotary shaft 3a of the temporary holding section 1 are connected via the gears 4, 5 and the timing belt 6, but are temporarily connected to the rotary drive shaft of the motor M. The rotating shaft of the holding unit 1 may be connected via a coupling.

[0023]

The device of the present invention determines whether rotation is performed normally at the beginning of rotation of the temporary storage unit using the detection patterns detected by PH1 and PH2, and only when the determination is correct, the temporary storage unit Is rotated to a predetermined collection position or a return position, so that a malfunction of the temporary holding unit can be prevented.
