DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin dispensing apparatus used for a coin changer mounted on a ticket vending machine, a vending machine, and the like.

[0002]

2. Description of the Related Art A coin dispensing apparatus used in a conventional coin changer will be described below. A conventional coin dispensing device has a configuration as shown in FIG.

[0003] In FIG. 4, B is a coin storage cylinder portion in which four storage cylinders for stacking and storing coins are connected, and A is a coin dispensing portion provided below the coin storage cylinder portion B. FIG. 5 shows the details of the structure of the coin payout section A.

[0004] That is, the coin dispensing section A includes a base 1 and
A slide plate 5 that is provided on the base 1 and pulls out the coins 2a at the lowermost part of the coin storage cylinder 3 in which the coins 2 are stacked and stored, drops the coins 2a to the bottom 1a of the base 1, and pays out the slide plates 5; The slider 4 was constituted by a slider 4 interlocked with a slide plate 5, and the slider 4 was connected to a drive motor 7 via a drive gear 6. Further, the motor 7 is connected to a detecting means 8 and a control means 9 for controlling the slider 4 as the payout means.

Further, in order to pay out the lowermost coin 2a among the coins stacked in the coin storage cylinder 3, the slide plate 5 shown in FIG. 6 is moved after the operation shown in FIG. 6
(B) Then, the reciprocating operation was performed in the order of returning to FIG. 6 (a). At this time, the movement of the paid-out coin 2a by the slide plate 5 and the operation timing of the slider 4 become abnormal due to deformation and dirt of the coin 2 or distortion of the structural parts, and the coin 2a was sometimes jammed. The state is a coin 2a by a slide plate 5 as represented in FIG.
In a biting state. As described above, once the coin 2a is bitten, an abnormal signal indicating that the coin 2a is jammed is transmitted, and the coin payout operation is stopped until the coin 2a is jammed.

[0006]

However, in such a conventional configuration, when an abnormal state such as a jam of coins occurs in the dispensing device in the coin changer, an abnormal signal is transmitted and the operation is stopped. Unless the serviceman removes the jammed coin 2a, there is a problem that the coin cannot be continuously used as a coin changer.

The present invention solves such a problem, and a coin dispensing apparatus capable of automatically clearing a jam of coins even if the coin is jammed in the coin dispensing apparatus of the coin changer. It is intended to provide.

[0008]

In order to achieve this object, a coin dispensing apparatus according to the present invention is provided by reciprocating a slide plate .
That a detecting means for detecting the dispensing operation, and control means for controlling the dispensing operation by the reciprocal of the slide plate is connected to the detection means is provided, after the dispensing operation by the reciprocal of the slide plate is started, previously If the detection signal from the detection means is not obtained within a predetermined time, the time required for payout by reciprocation of the slide plate
On the other hand , reverse rotation control means for automatically reversely moving the slide plate for a sufficiently short time is provided .

[0009]

With this configuration, even if coin jamming due to the slide plate occurs during the payout operation, the coin jamming is detected by the detecting means for detecting the coin jam, and then the sliding direction when the coin is jammed into the slide plate. The reverse rotation control is performed in the opposite direction, so that the jammed coin is automatically released. Therefore, even if a coin jam occurs, the jammed coin can be automatically released.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a coin dispensing apparatus according to one embodiment of the present invention.

Referring to FIG. 1, the coin dispensing apparatus of the present invention pulls out one coin 22a at the bottom of a base 21 and a coin storage cylinder 23 provided on the base 21 and in which coins 22 are stacked and stored. A slide plate 25 which is dropped on the bottom 21a of the base 21 and paid out;
Motor (used as an example of driving means) 27 for driving
It has. A slide plate 25 is connected to the motor 27 from a main shaft of the motor via a speed reduction mechanism. Further, the slide plate 25 moved by the driving of the motor 27 is provided with a detecting means 28 for detecting a moving time (a photo interrupter 13 as shown in FIG. 2 is used as a detecting means of the present invention. It is also possible to use the contact parts of the above), and a reverse rotation control means 30 controlled by a control means 29 based on an output signal of the detection means 28 is provided.

Further, the configuration of the payout section will be described in detail. FIG. 2 is a perspective view of an essential part for explaining a payout operation of the payout unit in the present invention.

In FIG. 2, reference numeral 11 denotes a payout drive motor, which performs predetermined reduction by gears 12 to 15, and
To the cranks 9 and 10. The rotational force transmitted from the drive motor 11 at a reduced speed is transmitted from the gear 8 to the cranks 9 and 10, where it is converted into a reciprocating linear motion (arrow a motion) of the slider 24. Further, the slider 24 is arbitrarily connected to one of the slide plates 25 (25a to 25e), and the slide plate 25 reciprocates integrally with the slider 24. By this reciprocating movement, the slide plate 25 pulls out the lowermost coin 22a of the coin 22 in the coin storage tube 23 formed above as shown in FIG. 1, and moves the coin 22a downward ( Payout).

Here, if the coin 22 is deformed or stained, the structural parts are distorted, etc., the coin 22a will not move even if the backward movement of the slide plate 25 starts (arrow B operation) as shown in FIG.
May not fall and become stuck (coin jammed). Conventionally, in this case, the coin changer sends an abnormal signal to stop and stop, so that it is necessary to remove a jammed coin.

However, in the present invention, FIG.
As shown in (b), when the coin 22a is jammed and jammed in the dispensing device, the detecting means 28 detects the dispensed coin jam (that is, a signal is obtained 5 seconds after the coin dispensing operation is started). When you can not
This coin jam signal is output. After the engagement by the reverse rotation control means 30, the slider 24 is automatically reversely slid in the direction opposite to the sliding direction until the detection means 28 detects it as standby position control. Furthermore,
As the reverse rotation time control, the maximum time is half the time (200 mS in the present invention) required for the slider 24 to normally pay out, and the slider 24 is automatically reversely slid in the direction opposite to the sliding direction.

That is, by performing such reverse payout control by both time control and position control (driving in the direction of arrow C in the figure), the coin 22a is dropped downward (return port) to release the jamming symptom. ing. As a result, the function of the coin changer can be returned to normal.

The reversal control operation is executed a plurality of times (three times in the embodiment of the present invention, but may be executed more times), so that the coins can be more effectively jammed. Exclusion performance can be improved.

[0018]

As described above, according to the coin dispensing apparatus of the present invention, the detecting means for detecting the reciprocating dispensing operation of the slide plate and the reciprocating dispensing operation of the slide plate are connected to the detecting means. Having a control means, after the reciprocating payout operation of the slide plate is started, when the detection signal from the detection means is not obtained within a predetermined time, the slide plate is automatically moved for a predetermined time. By providing the reverse rotation control means for performing the reverse movement, it is possible to realize an excellent coin dispensing apparatus which does not cause the coin dispensing jam.
