Description

[Detailed description of the invention] [Industrial application field] The present invention relates to coin handling machines such as coin counting machines and coin dispensing machines, and particularly relates to a rotating disk that feeds coins one by one into a coin passage using centrifugal force. .

[Conventional technology]

Conventionally, in a coin processing machine using a rotating disk, the coins to be processed fed onto the rotating disk are moved to the periphery of the rotating disk by centrifugal force caused by the rotation of the rotating disk, and the coins that are extended outward from the periphery of the rotating disk are removed. The coins are sent out onto a passageway, and necessary processing such as counting and identification is performed while the coins are being sent along the coin passageway.

A coin thickness regulating member was provided above the connecting portion between the rotary disk and the coin passage to regulate the thickness of passing coins so that two coins would not be sent out to the coin passage.

[Problem that the invention attempts to solve]

The coins supplied onto the rotating disk fall onto the top surface of the rotating disk, and the fallen coins are moved to the periphery of the rotating disk by the centrifugal force caused by the rotation of the rotating disk, and continue to move along the periphery of the rotating disk. After that, only the lowest layer of coins among the stacked coins are sent out to the coin passage by the coin thickness regulating member, but depending on the coin supply condition, the coins may fall onto the top surface of the rotating disk. Instead, the coins may move in an upright state, leaning against a peripheral wall provided at the periphery of the rotating disk, or leaning against each other. In this case, the coin in the upright state cannot fit under the coin thickness member, so it is not sent out to the coin passage, but circulates on the rotating disk several times, due to centrifugal force and the action of the coin thickness regulating member, etc. Then, after falling over, it is sent out to the coin passage as described above. In this way, when the supplied coins are in an upright state, there is a problem in that it takes time to send out the coins.

In addition, even if the coins are supplied onto a rotating disk and move around the periphery in an overturned state, some of the upper coins of the stacked coins may fall off the coin thickness regulating member depending on how the coins overlap. Since the coins on the lower side try to enter below, the coins get caught between the coin thickness regulating member and the rotating disk. If the coin stops while it is stuck, the delivery of the coin will be interrupted, and subsequent coins will become stagnant one after another, eventually locking the rotation of the rotating disk. . Therefore, there was a problem in that the rotating disk had to be rotated in the opposite direction or the stuck coins had to be removed manually.

The present invention was developed in view of the above-mentioned points, and an object of the present invention is to provide a rotating disk for a coin processing machine that can automatically overturn coins in an upright state and remove stuck coins. It is.

[Means for solving problems]

In the present invention, the centrifugal force of the rotating disk 11 moves the coins on the rotating disk 11 to the periphery, and the coins are stacked in one layer in the thickness direction by the coin thickness regulating member 19 provided facing the upper part of the periphery of the rotating disk 11. A coin passage 17 extending outward from the rotating disk 11
In a coin processing machine that performs necessary processing such as counting or identification while the coins are transferred through the coin passage 17, a coin is placed on the upper surface of the rotating disk 11 starting from the vicinity of the periphery of the rotating disk 11. A slotted hole 13 is formed so as to approach the center of the rotating disk 11 as it goes in the counter-rotation direction, and this slotted hole 13 stands up on the rotating disk 11 as the rotating disk 11 rotates. The coin is caused to fall over and the coin that is caught between the upper surface of the rotating disk 11 and the coin thickness regulating member 19 is removed.

[Effect]

In this invention, the lower part of the coin in an upright state is inserted into the slot of the rotating disc, and as the rotating disc rotates, the lower part of the coin is moved along the slot toward the center of the rotating disc. The coin, which was in an upright position, falls over, and the coin caught between the rotating disk and the coin thickness regulating member gets caught in the slot, and as the rotating disk rotates, the coin falls along the slot. By moving the coin toward the center of the rotating disk, the trapped coin is removed.

[Embodiment] Hereinafter, the configuration of an embodiment of the present invention will be described with reference to the drawings.

1 and 2, reference numeral 11 denotes a rotating disk whose upper surface is supplied with coins to be processed. It is rotationally driven in the rotation direction F shown. A groove hole 13 is formed on the upper surface of the rotating disk 11 so as to approach the center of the rotating disk 11 as it goes in the counter-rotation direction of the rotating disk 11, starting from the vicinity of the peripheral edge 11a of the rotating disk 11. 1
They are provided at four locations on the circumference of 1. The slots 13 are formed such that the adjacent slots 13 approach the center of the rotating disk 11 differently, and both opposing slots 1 on the circumference of the rotating disk 11
3 are formed symmetrically, and each slot 13
As shown in FIGS. 4 and 5, each groove hole 13 is formed in a substantially semicircular groove shape, and a dust hole 1 is provided at both ends of each groove hole 13 to remove dust that has entered the groove hole 13.
4 are provided to penetrate through the upper and lower surfaces of the rotating disk 11, respectively.

Along the outer peripheral edge of the rotating disk 11, the rotating disk 1
A peripheral wall 15 is disposed to support a coin that moves to the periphery due to the centrifugal force of 1, and a notch 16 is provided in a part of this peripheral wall 15. A coin passage 17 is provided along the direction.

A coin guide piece 18 that guides coins moving along the peripheral wall 15 toward the center of the rotating disk 11 is arranged on the entrance side of the coin passage 17, and this coin guide piece 18 is arranged on the starting end side (first (left side in the figure) is arranged on the peripheral edge 11a of the rotating disk 11, and the end side is arranged so as to approach the center of the rotating disk 11, and faces the top surface of the rotating disk 11 so that coins cannot pass therethrough. It is located.

A coin thickness regulating member 19 is disposed on the upper part of the rotating disk 11 extending from the end of the coin guide piece 18 to the coin passage 17, and feeds the coins to the coin passage 17 in a single layer in the thickness direction. This coin thickness regulating member 19 is arranged at a height relative to the upper surface of the rotating disk 11 that allows only one coin to pass through the coin passage 17, and is located at the edge of the coin thickness regulating member 19 and has two layers. Regulating edge 2 that restricts the passage of coins larger than 1
0 are arranged continuously at the terminal end of the coin guide piece 18, and are arranged so as to move away from the center of the rotating disk 11 as it goes in the rotation direction F of the rotating disk 11, that is, in contact with the peripheral edge 11a of the rotating disk 11. They are arranged so that the overlap width decreases, and their terminal ends are located at the peripheral edge 11a of the co-rotating disk.

The coin passage 17 includes a lower passage plate 21 whose upper surface is disposed substantially flush with the upper surface of the rotating disk 11, and an upper passage plate 22 whose lower surface is disposed approximately flush with the lower surface of the coin thickness regulating member 19. A long slot 23 is formed in the lower passage plate 21 along the coin passage 17, and a pulley 2 is disposed in the long slot 23 at the lower part of the starting end and the terminal end of the long slot 23.
A conveyor belt 26 spanning between the coin passages 4 and 25 is disposed to protrude above the coin passage 17, and the rotation of the conveyor belt 26 in the conveying direction presses the coins fed into the coin passage 17 against the upper passage plate 22. The coins are conveyed toward the terminal end of the coin passage 17.

In addition, notches 27 and 28 are formed in the lower passage plate 21 and the upper passage plate 22 so as to face each other facing the coin passage 17.

Next, the operation of this embodiment will be explained.

The coins supplied onto the rotating disk 11 move to the periphery of the rotating disk 11 due to the centrifugal force caused by the rotation of the rotating disk 11, and then move along the periphery.
The coin is moved toward the center of the rotating disk 11 by the coin guide piece 18 . Then, when the coin guide piece 18 reaches the end and the coin guide piece 18 is no longer restricted, the coins in the lowest layer touching the upper surface of the rotating disk 11 are
Due to the centrifugal force of 1, the coin jumps out in the tangential direction and enters under the coin thickness regulating member 19, and is conveyed through the coin passage 17 by the conveyor belt 26. On the other hand, the second or higher layer coins riding on the upper surface of the coins fed into the coin passage 17 come into contact with the regulating edge 20 of the coin thickness regulating member 19 and move along this regulating edge 20. Then, it moves along the periphery of the rotating disk 11 again.

Also, depending on the supply condition, the coins that stand up on the rotating disk 11 are placed on the peripheral wall 1 provided at the periphery of the rotating disk 11, as shown in FIGS. 3 and 4.
5, the coins are in a state of leaning against each other, and there is very little contact between the coin and the rotating disk 11, so there is little friction, so the coin in the upright state is
It moves considerably behind the rotational movement of the rotating disk 11. Therefore, the lower part of the coin gets caught in the slot 13 of the rotating disk 11, and this rotating disk 11
As the coin rotates, the lower part of the coin is moved toward the center of the rotating disk 11 along the slot 13, and the coin, which was in an upright position, falls over.

Also, as shown in FIGS. 3 and 5, depending on how the coins overlap, a part of the upper coin among the overlapped coins may get under the coin thickness regulating member 19, and then When a part of the lower coin enters into the space between the upper surface of the rotating disk 11 and the coin thickness regulating member 19, the part of the lower coin below the upper coin becomes The upper coin is pressed against the upper surface of the rotating disk 11, and when the slot 13 of the rotating disk 11 comes into contact with it, a part of the periphery of the lower coin gets caught in the slot 13, and the rotating disk 11, the lower coin is moved along the slot 13 toward the center of the rotary disk 11, and the lower coin is pulled out from the lower part of the upper coin to be released.

Note that the slot 13 of the rotating disk 11 is
1. One or more slots 13 may be formed on the upper surface of the rotary disk 11, and the shape of the grooves 13 may also be different from the peripheral edge 11 of the rotating disk 11.
The slot 13 may have a linear shape or a curved shape as long as it is formed so as to approach the center of the rotary disk 11 in the counter-rotation direction of the rotary disk 11 starting from the vicinity of point a.

[Effect of idea]

According to the present invention, since a slot is provided on the top surface of the rotating disk, the lower part of an upright coin can be caught in this slot, and the coin can be instantly overturned by the rotation of the rotating disk. This allows quick feeding without wasting time in feeding the coins into the coin passage, and also allows coins caught between the rotating disk and the coin thickness regulating member to be caught in the slot. The coin is removed by the rotation of the rotating disk and the coin jamming condition is automatically resolved.
As in the past, every time a coin gets caught, the machine is stopped and the stuck coin is manually removed.
It is possible to eliminate the need for removing stuck coins by rotating the rotating disk in the opposite direction.
