Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for discharging coins (including metal coins), which is used in a vending machine or the like.

[Conventional technology]

Vending machines are provided with coin ejecting devices for discharging change, and arcade game machines are provided with metal payout devices for refunding the number of metal coins corresponding to winnings. Note that since this has the same configuration as the coin ejecting device described above, it will also be referred to as a coin ejecting device in this specification. As shown in Japanese Unexamined Patent Publication No. 51-72395, conventional coin ejecting devices store a large number of coins in a stacked state in a coin storage tube that is slightly larger than the coins. A push-out plate is arranged at the bottom of the storage tube so that it can be taken in and out. The push-out plate is connected to a disc or cam rotated by a motor via a connecting member such as an arm, and linearly reciprocates once per rotation of the motor to push the bottom of the coin storage tube. It is designed to push out one coin.

[Problem that the invention attempts to solve]

In such conventional coin ejecting devices, the tip of the extruding plate that slides or swings pushes the back of the coin, so it is not possible to eject the coins at a high speed. Further, since it is necessary to take a large coin extrusion stroke of the extrusion plate, there is a drawback that the device becomes large.

Furthermore, when counting the number of coins that have been ejected, since the pushing plate may spin idly, conventionally a micro switch is installed in the path of the ejected coins to detect the passing of coins. I have to. Therefore, when the coin ejecting device is sold as a unit, the manufacturer who purchases the device must install a microswitch, which is extremely inconvenient.

[Purpose of invention]

The present invention provides a coin ejecting device that can eject coins at a high speed and is convenient when installed in a vending machine etc. by incorporating a switch for detecting coin ejection into the coin ejecting device. The purpose is to

[Means for solving problems]

In order to achieve the above object, the present invention includes a push-out plate for pushing out the coins at the bottom of the coin storage tube, an arm that rotates when pressed by the coins pushed out by the push-out plate,
A spring that biases this arm in the return direction, that is, a direction closer to the push-out plate, and a switch that is operated by this arm when the arm is rotated by the pressure of the coin that has been pushed out. It was established.

[Effect]

According to the above configuration, the coin pushed out of the coin storage tube by the push-out plate is once held between the arm and then the push-out plate further moves to push the arm against the spring. You will be able to rotate it. As the arm is rotated as the coin is pushed, when the center of the coin passes through the contact area with the arm, the restoring force of the spring stored by the rotation of the arm is released. , the arm returns to its original position with force. At this point, the rear end of the coin is still partially held between the push-out plate and the arm, so as the arm returns forcefully as described above, the coin is thrown away. It is a matter of fact. Further, when the arm rotates while holding a coin between it and the push-out plate, the arm operates a switch, so that the discharge of the coin can be detected by this switch.

〔Example〕

1 and 2, a motor base 11 is fixed to the lower part of an L-shaped base, and a motor 12 with a speed reducer is attached to this. A substantially crank-shaped plate 13 is fixed onto the motor base 11, and a motor shaft 14 projects so as to pass through the plate 13 and the motor base 11. A disk 15 is fixed to the upper end of this motor shaft 14,
It is rotated by a motor 12.

As shown in detail in FIG. 3, the disk 15 and the push-out plate 17 are connected by a telescopic connecting means 18. The connecting means 18 includes a link 19 having a substantially U-shape and a spring guide 20 having a substantially L-shape. Said link 19
The long bent portion 19a and the short bent portion 1
9b and a long hole 19c are formed, and the vicinity of the bent portion 19a is screwed into the disk 1 by means of a screw 21.
5 for rotation. The spring guide 20 is formed with a bent portion 20a and a long hole 20b corresponding to the long hole 19c of the link 19, and the bent portion 20a is formed in the link 19.
The screw 22 is placed over the bent portion 19b of the
The tip of the spring guide 20 is fixed to the slot 19 formed in the bent portion 19a.
It is fitted in d. A coil spring 23 and a spring receiver 24 are fitted into the spring guide 20, and the spring receiver 24 is urged rightward by the coil spring 23. The long hole 19c and 2
A pin 25 is fitted into 0b, and this pin 25
is planted on the extrusion plate 17. In addition,
Reference numeral 26 is a washer, and reference numeral 27 is a pin that prevents the washer 26 from coming off.

Two spacers 32 are placed on the plate 13 to form an ejection port 31 for the coin 30.
33 is arranged, and a guide cover 34 is fixed thereon. A space somewhat larger than the thickness of the coin 30 is formed by the plate 13 and the guide cover 34, and the extrusion plate 17 is housed in this space so as to be rotatable about the shaft 35. The guide cover 34 has a hole 34a to which the lower end of the coin storage tube 36 is fixed, and a hole 34a through which the pin 2 is fixed.
A notch 34b into which the number 5 is inserted is formed.

An arm 40 biased counterclockwise by a spring 39 is disposed above the guide cover 34 and rotatably supported by the shaft 35 . A pin 41 protruding downward is implanted at the tip of the arm 40, and a collar 42 is fitted into the pin 41. This pin 41 passes through the slot 34c of the guide cover 34, etc. When the arm 40 is pushed by the coin 30, it rotates clockwise to turn on the micro switch 43.

The operation of the embodiment of the present invention configured as described above is as follows. Before the coin is ejected,
Since the push-out plate 17 is stopped at the position shown in FIG. 2, the push-out portion 17a of the push-out plate 17 is
It is retracted from the bottom of the coin storage tube 36. When coins are ejected, the motor 12 is driven by a control circuit (not shown) to rotate the disk 15 at high speed. Since the disc 15 is connected to the push-out plate 17 via the connecting means 18, the push-out plate 17 is pushed and rotated clockwise.

As shown in FIG. 4, when the push-out plate 17 is rotated, its push-out portion 17a enters the lower part of the coin storage tube 36, thereby pushing the coin 30 at the bottom of the coin storage tube 36. This pressed coin 30 moves along the end face of the spacer 33 and hits the collar 42, so the arm 40 is rotated clockwise against the spring 39. This arm 40 retreats along the slot 34b etc. and turns on the micro switch 43 with a part of it.

When the pushing plate 17 further rotates clockwise, the center of the coin 30 passes through the collar 42. When the center of the coin 30 passes through the collar 42, the arm 40 rapidly returns counterclockwise due to the stored force of the spring 39, so the coin 30 is pushed back by the arm 40 and exits from the outlet 31 as shown in the arrow in FIG. Jump out at high speed in the direction indicated by the line. The coin 30 ejected from the discharge port 31 enters a coin receptacle (not shown) via a chute (not shown). Even after this coin 30 is ejected, the disc 15 continues to rotate clockwise, but in this case, the pushing plate 17 rotates counterclockwise, so the pushing plate 17 rotates counterclockwise.
7a retreats from the lower part of the coin storage tube 36.

When the arm 40 is returned to the position shown in FIG. 2 by the spring 39, the micro switch 43 is activated.
turns off, and it is detected that one coin has been ejected. This micro switch 43
A counter (not shown) is set up at the timing of turning off. Similarly, the disk 15
One coin is ejected every time the motor 12 rotates once, and when a predetermined number of coins have been ejected, the rotation of the motor 12 is stopped and the ejection of coins is completed.

When the push-out plate 17 retreats from the lower part of the coin storage tube 36, the coin to be pushed out next slides down from the push-out plate 17 in an oblique state. When the push-out plate 17 swings at high speed, the push-out plate 17 enters the lower part of the coin storage tube 36 before the fallen coin settles horizontally on the plate 13, causing the coin to fall diagonally. Extrusion part 17 above or below the coin that is floating
a may get in there, causing the push-out plate 17 and the coin to engage with each other. In this case, disk 1
5 rotates, the pin 25 remains in the long holes 19a, 20b.
Since it can escape along the extrusion plate 1
Only the disc 15 rotates while the disc 7 remains stopped. Then, the disk 15 further rotates and the extrusion plate 17
When the retraction stroke starts, the push-out plate 1
7 rotates counterclockwise and leaves the coin. As a result, the push-out plate 17 and the coin are disengaged, so that the coin falls onto the plate 13 and becomes horizontal, and the coin is reliably ejected in the next push-out stroke. In addition, the extrusion plate 17
The coin engages with the coin at the beginning of the extrusion stroke, so the micro switch 43 is turned on.
It has not been. Therefore, no counter is set up in this case.

[Effect of idea]

As explained above, in the coin ejecting device of the present invention, unlike the case where coins are ejected simply by the stroke of the pushing plate, the coins pushed out by the pushing plate are biased by the spring in the return direction. The coin is received by the arm that is held in place, the coin is held between the pushing plate and the arm, and the coin is pushed out while rotating the arm against the spring, and the coin is held between the pushing plate and the arm. When the center of the coin passes over the contact area between the coin and the arm, the stored force of the spring is released, and when the arm returns to its original position, the coin is thrown away with force. In this way, by bouncing the coins and ejecting them, it is possible to increase the coin ejection speed while reducing the movement stroke of the pusher plate compared to the case where the coins are ejected only by the pusher plate. It becomes like this. Furthermore, the arm that rotates while holding the coin between it and the push-out plate and is used for flipping the coin is also used to operate the coin ejection detection switch, which is different from the conventional arm. There is no need to separately install a switch at a position away from the coin ejecting device, unlike other devices, and there is also the effect that it can be easily incorporated into a vending machine or the like.
