Abstract

PURPOSE:To enable a single drive source to actuate individually plural coin holding plates by opening selectively a certain coin holding plate in accordance with the revolving direction of a rotary drive member and at the same time supporting the load of coins applied to the coin holding plate via a fixed locking part. CONSTITUTION:When a rotary drive member 15 is revolved, a coin holding plate 6 or 7 is actuated in accordance with the revolving direction of the member 15. At the same time, a link 16 or 17 is detached from a fixed locking part 18 or 19 when the plate 6 or 7 is opened. Meanwhile a part near one of both ends of the link 16 or 17 is locked by the part 18 or 19 at a basic position. As a result, both plates 6 and 7 can be selectively actuated by a single drive source. Thus the satisfactory supporting force is secured even when a large number of coins are held.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a coin temporary holding device that temporarily holds coins in a deposit machine or the like and selectively sends the held coins to a storage box and a return slot. It is something.

[Conventional technology]

As a conventional device of this kind, for example,
As shown in the 018M publication, the coin holding chamber is provided with a pair of coin holding plates whose upper ends are rotatably supported and whose lower ends are closed in the basic state, while two coin holding plates are provided on the outside of the coin holding chamber. A pair of solenoids are arranged in parallel, a pair of levers are pivotally attached to the upper end of the movable core of each solenoid, one end of each of these levers is supported by a pivot shaft, and a guide groove is provided at the other end of each of the above. It is known that a coin protruding from the coin retaining plate is engaged with the guide groove.

According to this device, each coin holding plate is individually actuated by each of the solenoids via a lever. When the lower ends of both coin holding plates are closed, coins are held, and when one coin holding plate is selectively opened, coins are placed in either the storage box or the return slot. It is discharged.

(Problems to be Solved by the Invention) However, the conventional device as described above requires a separate drive source (solenoid) for each coin holding plate, which has drawbacks such as increased cost. In addition, when both coin storage plates are closed and coins are stored on them, the load is supported by the engagement portion between the bin protruding from the coin storage plates and the guide groove of the lever. With such a support structure, it is difficult to ensure a large supporting force, and therefore there is a problem in that the number of coins that can be temporarily held is limited.

In view of these circumstances, the present invention allows each coin holding plate to be operated individually with a single drive source, and also allows a large number of coins to be temporarily held by increasing the load supporting force when holding coins. A coin temporary storage device is provided.

[Means to solve the problem]

The present invention includes a pair of coin holding plates inside a coin holding chamber having two coin sending ports at the bottom, and each upper end of the pair of coin holding plates has a rotating shaft on both sides of the coin holding chamber. In the coin temporary holding device, each of the coin holding plates is rotatable between a basic state and an open state, with a basic state in which the lower ends of both coin holding plates are closed. a pair of levers fixed to respective ends and biased in the direction of closing the coin holding plate; a rotary drive member located between the two levers, pivoted on a fixed wall and rotated by a drive means; , a pair of links connecting each of the levers and the rotational drive member, and a fixed locking portion that locks a portion near one end of each of the links so as to support the load of the coin held on the coin holding plate. Each of the links has one end connected to the lever so as to be movable relative to the lever in the length direction of the link by a predetermined distance so as to allow separation from the fixed locking part, and a biasing means. The other end is connected to the rotational drive member so as to interlock the lever only in the direction of opening the coin retaining plate.

(Function) According to the above configuration, when the lower end of the coin holding plate is closed and coins are held on the coin holding plate, the load applied to the coin holding plate is applied to the coin holding plate through the rotation shaft, the lever and the link. It is supported by a fixed locking part and provides sufficient supporting force. Also, when the rotational drive member is rotated in one direction, one link moves to a position where it is released from the fixed locking part, and then the lever is rotated, which opens one coin holding plate. be done. The rotary drive member is located between the pair of levers, and each lever is interlocked with the rotary drive member only in the direction of opening the coin holding plate, so that the rotary drive members are arranged symmetrically. Then, one of the coin retaining plates is selectively opened depending on the direction of rotation of the rotational drive member.

In addition, on the outer surface of the end of the hopper 1 opposite to the side where such a mechanism is provided, the basic position and open position of each coin holding plate 6.7 are marked as shown in FIG. Sensors 51 to 54 are provided for detection, respectively. These sensors 51 to 54 are constituted by, for example, photo sensors, and are designed to detect the tip of a detected lever 55, 56 attached to a rotating shaft 8, 9.

The operation of the coin temporary storage device of this embodiment as described above will be explained with reference to FIGS. 4 to 7.

When in the basic state shown in FIG. 4, both coin holding plates 6.
7 is queried, and in this state both coin holding plates 6.7
A load P of the coins is applied to the coin holding plates 6 and 7 by holding the coins thereon. This will cause link 16.17
A force in the direction of arrow a is applied to the outer end of the link 16.
．． A fixed locking portion 18 abuts from above near the outer end of the link 16, 17, thereby preventing movement of the links 16, 17. Therefore, the coin holding plate 6.7 is prevented from opening, and the load is supported by the fixed locking portion 18, and a sufficient supporting force for the load is obtained, so that a large number of coins can be held.

From this state, when the coin retaining plate 6 on the left side in the figure is operated to the open state in response to a signal instructing coin feeding, the rotational drive member 15 is driven by the motor as shown in FIG. By rotating counterclockwise (arrow b), only the link 16 moves as shown by arrow C while the lever 11 remains at the basic position within the range of relative movement between the long hole 41 and the engaging pin 21. By moving inward approximately horizontally, the link 16 is disengaged from the fixed locking portion 18. Then, after the link 16 moves to a state where the outer end of the elongated hole 41 comes into contact with the engagement pin 21, when the rotational drive member 15 further rotates, the link 16 moves as shown in FIG.
With this movement, the lever 11, the rotation shaft 8, and the coin holding plate 6 rotate around the co-movement #18 (arrow d). As a result, the coin holding plate 6 becomes open, and the coins are sent out from the coin delivery port 4.

When such an opening operation of the left coin holding plate 6 is performed, the right link 17 does not cause the rotational drive member 15 and the lever 12 to interlock. That is, when the rotary drive member 15 rotates counterclockwise as described above, the engagement pin 36 of the rotary drive member 15 moves relative to the link 17 on the right side within the elongated hole 44, so that the link 17 Although the inner end side swings up and down, it does not move in the direction in which the lever 12 is pulled, and the lever 12 is kept at the basic position by being biased by the spring 28. Therefore, the coin retaining plate 7 on the right side is held in a state of shielding the coin delivery port 5.

When the coin retaining plate 6 is operated to the predetermined open position shown in FIG. 6, the rotation of the rotary drive member 15 is stopped in response to a signal from the sensor 52 that detects the open position.

When the state shown in FIG. 6 is returned to the basic state, the operation is opposite to that at the time of opening, that is, as the rotation drive member 15 rotates in the return direction, the lever 11 and the link 16 are moved by the spring 27 and the link 16, respectively. 37, the lever 11, rotating shaft 8 and coin holding plate 6 return to their basic positions as shown in FIG. Return to. At this time, in response to a signal output from the sensor 51 when the state shown in FIG. 7 is reached, the rotary drive member 15 continues to rotate by a certain angle from this point, and the rotary drive member 15 returns to the basic position. When the rotation is stopped.

4 to 7 show the case where the coin holding plate 6 on the left side is operated, but by rotating the rotary drive member 15 in the opposite direction to that in this case, the coin holding plate on the right side is also activated in the same way. Ru.

[Effects of the Invention] As described above, according to the coin holding device of the present invention, a pair of levers are respectively fixed to the rotating shafts of a pair of coin holding plates, and a driving means is located between the pair of levers. When the rotary drive member rotates, the rotation drive member is rotated by a rotary drive member, and a pair of links that interlock each lever with respect to the rotary drive member only in the direction of opening the coin holding plate. Since only one of the coin holding plates is operated, each coin holding plate can be selectively operated using one driving source. Furthermore, a fixed locking portion is provided for the link, and the link is allowed to move relative to the lever within a certain range, so that the link is released from the fixed locking portion when the coin holding plate is opened. In the basic position, the part near one end of the link is locked to the fixed locking part, so the load of the coins applied to the coin holding plate when holding coins is supported by the fixed locking part, and a large amount of coins can be held. It is possible to ensure sufficient supporting force even when
