Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a coin processing machine such as a coin counting machine or a coin dispensing machine. 1 layer in the thickness direction
This invention relates to a coin thickness regulating device that feeds coins one by one into a coin passage.

[Conventional technology]

Generally, a coin processing machine using a rotating disk has a fourth
As shown in the figure, the coins to be processed that are supplied onto the rotating disk 1 are moved to the peripheral edge 2 by the centrifugal force caused by the rotation of the rotating disk 1, and the coins are extended outward from the peripheral edge 2 of the rotating disk 1. The coins are sent out onto the coin passageway 3, and while the coins are being fed on the coin passageway 3, necessary processing such as counting and identification is performed.

In such a coin processing machine, the coin passage 3
A coin thickness regulating device 4 is provided above a portion where the rotary disk 1 and the coin passage 3 are connected to each other so that two coins are not sent out in a pile.

Conventionally, the coin thickness regulating device 4 has a rotating disk 1.
The coin thickness regulating member 5 is provided in an overlapping state with an interval that allows only one coin to pass through between the coin thickness regulating member 5 and the coin thickness regulating member 5. The shape of the regulating edge 6 of the thickness regulating member 5 is oriented toward the center of the rotating disc 1 as it goes in the rotation direction F of the rotating disc 1 from the peripheral edge 2 of the rotating disc 1 as a starting point. It is formed so that the overlapping width with the regulating member 5 is increased, and the shape is such that it approaches the peripheral edge portion 2 again after passing the entrance of the coin passage 3.

The coin thickness regulating member 5 allows only the coins in the lowest layer of the coins moving in an overlapping state along the peripheral edge 2 of the rotating disk 1 to pass through and sends them out to the coin passage 3, and also allows the coins in the second layer and above to pass through. The coin of
It moved along the regulating edge 6 of the coin thickness regulating member 5, and after the coin thickness regulating member 6 disappeared, it moved again along the circumferential edge 2 of the rotating disk 1.

[Problem that the invention attempts to solve]

The coins supplied onto the rotating disk 1 are
The peripheral edge 2 of the rotating disk 1 due to the centrifugal force caused by the rotation of
After being moved as it is along the peripheral edge 2 of the rotating disk 1, only the lowest layer of coins among the stacked coins are sent out to the coin passage 3 by the coin thickness regulating member 5, and the coins in the second and higher layers are The coins are moved toward the center of the rotating disk 1 along the regulating part 6 of the coin thickness regulating member 5, but depending on the condition of the coins being overlapped, the upper coin of the overlapped coins may be moved. A part of the coin gets under the coin thickness regulating member 5, and the lower coin tries to get under that coin, so the coin gets caught between the coin thickness regulating member 5 and the rotating disk 1. Occur.

When the bitten coin rotates together with the rotating disk 1, the coin thickness regulating member 5 approaches the center of the rotating disk 1 in the rotation direction F of the rotating disk 1, and overlaps with the rotating disk 1. As the width increases, the biting of the coin becomes even deeper, and eventually the rotation of the rotating disk 1 is locked. For that purpose, rotating disk 1
There was a problem in that it was necessary to rotate the coins in the opposite direction or to manually remove the stuck coins.

The present invention was developed in view of the above-mentioned points, and an object of the present invention is to provide a coin thickness regulating device for a coin processing machine that prevents coins from being caught between the rotating disk and the coin thickness regulating member. It is something to do.

[Means for solving problems]

The present invention moves the coins on the rotating disk 11 to the periphery by the centrifugal force of the rotating disk 11, and the coins are placed at a height facing the upper periphery of the rotating disk 11 to allow passage of only one coin. Thickness regulating member 1
9, the coins are layered in the thickness direction to form a rotating disk 1
In a coin handling machine that sends coins from 1 to a coin passage 17 extending outward, and performs desired processing such as counting or identification while the coins are transferred through this coin passage 17, a coin is placed on the periphery of the rotating disk 11 A coin guide piece 18 that guides a coin moving along the coin from the periphery to the center side, and a shape that starts from near the end of the coin guide piece 18 and moves outward in the radial direction of the rotating disk 11 as it goes in the rotation direction of the rotating disk 11. The thickness regulating member 19 has a regulating edge 20 of .

[Effect]

In the present invention, the coins supplied onto the rotating disk are moved to the center side of the rotating disk by the coin guide piece, and when the coin guide piece is no longer restricted,
The centrifugal force of the rotating disk sends only the lowest layer of coins to the coin passage, and even if a coin is caught between the rotating disk and the coin thickness regulating member, it will be sent out as it goes in the direction of rotation of the rotating disk. The coin thickness regulating member is then removed from the upper surface of the rotating disk, and the coin is released as the rotating disk rotates.
