Description

[Detailed description of the device] "Industrial application field" This device is installed in trains, buses, etc., and is installed in a fare box for collecting the fare of coins. After confirmation, it relates to a coin batch discharging mechanism that discharges downward.

"Prior Art" Fig. 3 shows a conventional coin batch discharge mechanism in a fare box. Acrylic transparent plate 11 is installed diagonally vertically,
A damper 13 having a receiving plate 12 closely facing the back surface (lower side) of the
Is rotatably arranged. The coins 14 slide down in the gap between the transparent plate 11 and the receiving plate 12 from an oblique direction, are caught by the claws 15 at the lower end of the receiving plate 12, and are accumulated, and the inserted amount is visually confirmed. When the accumulated coins 14 reach a certain number, the damper 13 is rotated to open the lower portion of the damper 13 with respect to the transparent plate 11 as indicated by a chain double-dashed line, and the accumulated coins are collectively discharged downward.

The upper end of the damper 13 is rotatably connected to the frame 17 by a stop shaft 16, and the damper 13 is always pulled toward the transparent plate 11 by a tension spring 18. Further, the damper 13 is a connecting rod 19
It is connected to the plunger 22 of the solenoid 21 via.
The solenoid 21 is fixed to the frame 17, the plunger 22 is pulled in the direction of the arrow by the suction of the solenoid 21, and the damper 13 rotates about the stop shaft 16 against the force of the tension spring 18 (see FIG. 3). Therefore, the coins 14 accumulated in the gap between the receiving plate 12 of the damper 13 and the transparent plate 11 are released and discharged downward by free fall.

"Problems to be solved by the invention" In the conventional coin batch discharge mechanism, when the damper 13 is opened to discharge coins, the damper 13 must be rotated until the receiving plate 12 facing upward faces downward. Coins were sometimes caught in the lower claw 15 and not ejected. Since the opening angle of the damper 13 is large, the size is large as a whole, and it is necessary to use a large and expensive solenoid 21 having a large stroke and suction force.

It is an object of the present invention to provide a coin batch discharging mechanism which can prevent the coins from being stagnant or caught in the damper when the coins are discharged, and the opening angle of the damper can be made smaller than that of the conventional one, so that the coin can be downsized.

[Means for Solving the Problems] According to the present invention, a damper is rotatably arranged between a transparent plate and a frame, and a receiving plate of the damper closely opposes the transparent plate to insert coins into them. The upper end of the damper is rotatably attached to a stop shaft fixed to the frame, and the damper is rotationally biased by a first tension spring so that its receiving plate approaches the transparent plate. A coin hook is rotatably attached to the damper so as to face the opposite side of the damper from the transparent plate, and the claw at the lower end of the coin hook projects to the transparent plate side from the lower end of the receiving plate, so that the coin hook The upper end of the coin is an engaging portion that can be engaged with the frame, and the coin hook is pivotally biased by the second tension spring so that the pawl projects from the receiving plate. Coins between the receiving plates are received. Drive means are provided which can rotate the damper so that the receiving plate separates from the transparent plate against the spring force of the first tension spring. When the damper is rotated by this driving means, the engaging portion of the coin hook engages with the frame, the coin hook rotates against the second tension spring, the claw retracts from the receiving plate, and the receiving plate. More coins fall.

In other words, in this invention, the damper part is separated into a damper that opens and closes with respect to the transparent plate by the driving means and a coin hook that has a claw that supports the coin and prevents the coin from falling, and when the coin is discharged, the claw of the coin hook is dampered. By pulling the coin from the receiving plate, the coin can be prevented from being caught, the coin can be completely discharged, and the turning space of the damper can be reduced.

[Embodiment] FIG. 1 shows an embodiment of the coin batch discharging mechanism according to the present invention, and the portions corresponding to those in FIG. Also in this invention, the damper 13 having the receiving plate 12 is provided, but the receiving plate 12 is not provided with the claw 15. Instead, a coin hook 23 for supporting coins on the opposite side of the receiving plate 12 from the transparent plate 11 to prevent the coins from falling is provided with a damper 13 by a stopper shaft 34
, The coin hook 23 has a degree of freedom around the stop shaft 34. The claw 24 at the lower end of the coin hook 23 projects from the lower end of the receiving plate 12 toward the transparent plate 11 side. The coin hook 23 is pivotally biased by the second tension spring 25 so that the claw 24 projects from the receiving plate 12, and the transparent plate 11 and the receiving plate 12 are projected by the projecting claw 24.
The coins 14 inserted in between are caught and prevented from falling. The upper end of the coin hook 23 approaches the frame 17 and serves as an engaging portion 26 that can engage with the frame 17. The damper 13 is rotated and biased by the first tension spring 18 so that the receiving plate 12 approaches the transparent plate 11, and the damper 13 is rotated by the solenoid 21 as a driving means against the first tension spring 18. it can. The lower end of the receiving plate 12 is engaged with the protrusion 27 of the transparent plate 11 while the damper 13 is rotated toward the transparent plate 11 side.
The distance between 11 and the receiving plate 12 is set to a predetermined value so that the coins 14 can easily reach the claw 24 one by one without overlapping.

When the coins 14 accumulated between the transparent plate 11 and the receiving plate 12 become a certain amount and the solenoid 21 is de-energized, its plunger 22
Is sucked, the damper 13 is rotated against the first tension spring 18, and is separated from the transparent plate 11 as indicated by a chain line. At this time, the engaging portion 26 of the coin hook 23 engages with the frame 17, the coin hook 23 rotates counterclockwise in the figure against the second tension spring 25, and as shown by the chain line. 24 withdraws from backing plate 12. Therefore, the coin 14 on the receiving plate 12 is dropped and discharged without being caught by the claw 24. In this way, the claw 24 is retracted and the coin 14 is dropped, so that the opening angle of the damper 13 can be much smaller than in the conventional case.

FIG. 2 shows that the inserted coin 14 is guided by the guide plate 28 and guided between the transparent plate 11 and the receiving plate 12, and the damper 13
The coins 14 dropped from the receiving plate 12 by the rotation of are supplied to the discharge path 29. The transparent plate 11 is fixed to the frame 17, and the plunger 22 of the solenoid 21 fixed to the frame 17 has a string 31.
This is the case when it is connected to the damper 13.

[Advantage of Invention] According to the present invention, as described above, the coin hook for supporting the coin of the damper part is structurally independent, and the claw 24 of the coin hook 23 is automatically retracted from the receiving plate 12 at the time of discharging, thereby the coin.
Since 14 can be completely discharged and the opening angle of the damper 13 can be made small, the stroke of the solenoid 21 can be small, and an inexpensive and small solenoid with a small suction force can be substituted. Since the damper 13 rotates little, it can be made compact. Further, since the coin hook 23 is operated by using the turning force of the damper 13, it is possible to realize cost reduction and weight reduction.
