[Prior art]
2. Description of the Related Art Conventionally, there is known an apparatus for polishing a coin by passing the coin between a pair of polishing cloths urged in a direction in which the coin approaches.
However, in this polishing method, since coins are polished in a line, the polishing time of coins is a time to multiply the number of coins, and it takes a long polishing time. In addition, a device for sending coins in a row was required.
On the other hand, as a coin counting device, a coin is inserted on a rotating disk, the coin is moved to the inner surface of the annular outer peripheral frame by centrifugal force, and the coin is discharged one by one from its opening while rotating along the inner surface of the outer peripheral frame. There is known a structure in which a coin detector and a coin counter are provided at the location.
In this coin counting device, the inserted coins are thrown on the inner surface of the outer peripheral frame at a high speed by centrifugal force, accumulated so that a large number of coins overlap the inner peripheral portion of the outer peripheral frame, and circulate at this position until discharged. There is a problem in that the contact between coins and the contact between the coin and the inner surface of the outer peripheral frame increase, and the damage to the inner surface of the coin and the outer peripheral frame is great.
Furthermore, in order to count coins and polish coins, two devices, a coin polishing device and a coin counting device, are required. In addition, each device is provided with a coin single-row feeding device that sends coins in a single row, which increases costs, increases the size of the device, and reduces the processing speed.

[0005]
[Action]
In the present invention, when a coin falls from the insertion slot, the coin moves on the center of the rotating disk and moves outward by centrifugal force due to the rotation of the rotating disk. The coin moves on the bristles provided outside the rotating disk and is sandwiched between the upper fixed bristles or the lower bristles and the upper bristles moving at a relative speed. While the coin moves outward due to centrifugal force, the upper and lower surfaces of the coin are polished by the upper and lower brush bristles, come into contact with the inner surface of the outer peripheral frame, roll along the inner surface of the outer peripheral frame, and discharge coins from the opening to the multi-row discharge path It will be discharged through. In the coin multi-row discharge path, the coin detector detects the passage of a plurality of coins, sends a coin detection signal to the coin counter, and adds and counts the number of passing coins.
Also, the coins are fed slowly to the extent that they move to the outer frame by the frictional force between the upper and lower brush bristles, and become one row on the inner surface of the outer frame. In other words, the discharge processing speed of coins ejected from the opening and the feed processing speed to the inner surface of the outer frame can be made substantially the same, so the coins move smoothly so that they do not overlap or form multiple rows on the inner surface of the outer frame. become able to. As a result, contact between coins and the inner surface of the outer peripheral frame is reduced, and damage can be reduced.
Another important point in the present invention is that the polishing and counting operations for coins are completed in a single step, so that the processing speed can be greatly increased.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The distance between the upper end of the lower bristle planted on the upper surface of the rotating disk of the present invention and the lower end of the upper bristle is slightly shorter than the thickness of one coin, and the bristle is in contact with the coin surface to some extent with certainty. It is preferable to do so.
Providing a coin insertion guide tube below the insertion slot facilitates the movement of the coin to the bristles and prevents the coin from being jammed below the insertion slot.
The upper brush bristles can be rotated or fixed relative to the brush bristles of the lower rotating disk, but the fixing method is preferred because the structure and mechanism are simple.
As the coin detector, a plurality of LEDs are embedded on the road surface of the multi-row discharge path so as to intersect the discharge direction, and a light receiver is provided above the LEDs so as to face the plurality of LEDs. It is desirable that a coin passing between the two blocks can detect the passage of the coin by blocking the light of the LED, and can simultaneously detect the passage of a plurality of coins at the same time. The LED and the light receiver may be installed in reverse.
