Description

[Detailed Description of the Invention] [Object of the Invention] (Field of Use in Work) The present invention is a coin for a coin processing machine, such as a coin counting machine or a coin wrapping machine, which processes coins at high speed and continuously. The present invention relates to a sorting passage device, and more particularly, to a coin sorting passage device that identifies a coin to be conveyed and excludes different coins such as coins other than a predetermined coin and false coins based on the identification result.

(Prior Art) A conventional coin sorting passage device is, for example, the one shown in Japanese Patent Application No. 60-198552 filed by the applicant of the present invention, which is a basic device for eliminating different coins. The structure is
It is as shown in FIGS. 6 and 7. That is, a coin passage 2 on which coins sent from the rotary disc 1 slide, a conveyor belt 3 for pressing and transferring coins into the coin passage 2, and an identification unit (sensor) 4 for identifying coins to be transferred. , A stopper 5 provided on the downstream side of the identification portion 4 so as to be able to advance and retreat in the coin passage 2 for locking the transferred coin.
And a passage switching member 6 provided on the downstream side of the stopper 5 so as to be capable of advancing and retracting in the coin passage 2 in order to convert the transfer direction of different coins to another direction in the radial direction and remove the different coins from the conveyor belt 3. A predetermined coin dropping hole 7 provided at the end of the coin passage 2 (the sorting passage continues in the apparatus of Japanese Patent Application No. 60-198552), and a different coin dropping provided at a side position of the conveyor belt 3. And holes 8. In addition, stopper 5
Is swingably driven by a solenoid S, and the passage switching member 6
Is driven to rotate by a rotary solenoid RS.

Then, if the identification result of the coin identified by the identification unit 4 is a preset predetermined coin, the coin is conveyed as it is and drops into the predetermined coin drop hole 7. On the other hand, when the identification result is a different coin other than the predetermined coin, the passage switching member 6 is actuated to enter the coin passage 2, the transfer direction of the different coin is changed, and the different coin is removed from the conveyor belt 3. It is dropped into the drop hole 8. At the same time, the stopper 5 is actuated to enter the coin passage 2 and lock the next coin of the different coins. Then, after a lapse of a predetermined time, the conveyor belt 3 is reversed to temporarily return the coins locked by the stoppers 5 to the upstream side of the identification unit 4, the path switching member 6 and the stoppers 5 are retracted from the coin path 2, and Again, the conveyor belt 3 is rotated in the forward direction to restart the identification.

(Problems to be Solved by the Invention) In the conventional coin sorting passage device, when dissimilar coins conveyed by the conveyor belt 3 are excluded, since the conveyor belt 3 exists, the different coins are excluded in the radial direction. Therefore, the passage switching member 6 is inserted into the coin passage 2 on the same plane as the coin passage 2 to convert the transfer direction of different coins to the radial direction and select different coins from the predetermined coins. for that reason,
Since the passage switching member 6 has to be largely moved in the radial direction of the coin, the responsiveness is poor, the entry timing tends to be delayed, and different coins may flow toward the predetermined coin side.

In addition, since the passage switching member 6 must be kept inserted until the transfer direction of different coins is completely changed, the passage switching member 6 is allowed only when different coins among the coins that are continuously conveyed pass. It is difficult to instantaneously move in and out of the coin to remove only the different coins, and the stopper 5 for locking the next coin on the coin passage 2 is inevitable.

As described above, in the conventional apparatus, when the heterogeneous coins conveyed by the conveyor belt 3 are excluded, since the conveyor belt 3 exists, the passage switching member 6 that switches the passages to eliminate the different coins has a coin diameter of It is necessary to move the coin in the same direction, the movement amount is large and the responsiveness is poor, and therefore it is necessary to separately provide a stopper 5 for locking the next coin of different coins, and further, to operate each In order to do so, a drive source such as a solenoid is required, which causes a problem of high cost.

Further, since the passage switching member 6 and the stopper 5 are operated separately, there is a problem that the operation timing is very difficult to take.

The present invention has been made in view of the above problems,
Even when coins are transferred at high speed and continuously by the conveyor belt, if different types of coins are identified, the transfer direction of different types of coins is converted to the thickness direction of the coins to switch the passages to improve responsiveness. In addition, it is an object of the present invention to provide a low cost coin sorting passage device that does not require a special stopper for locking the next coin.
