FIG. 1 shows the details of the straightening device 6 as described above, and 10 is a straightening conveyor wound around a driving roller 11 and a driven roller 12. The coin a dropped from the end is supplied. Reference numeral 14 is a stopper that prevents the coin a from falling through the gap between the two conveyors and that is used for overturning the coin a. The plate-shaped inclined plate 14a and side plate 1 shown in the figure
4b and. Entry side 13 of rectifying conveyor 10
Is inclined so as to be lower than the exit side 15. This inclination angle θ is the coefficient of friction μ between the coin a and the rectifying conveyor 10.
When the rectifying conveyor 10 is made of leather or the like, μ is large at about 0.56. Therefore, if the inclination angle θ is set to about 29.2 ° or less, one coin a does not slip on the belt. Further, when coins a are overlapped with each other, μ between metals is small, about 0.15 to 0.20. Therefore, if the inclination angle θ is set to about 12 °, the coins a overlapped with each other slide down and are separated one by one. It enters the straightening roller 17 to facilitate straightening. A tension roller 16 is provided below the flow straightening conveyor 10. Above the rectification conveyor 10, rectification rollers 17 are arranged at intervals slightly wider than the coin a.
The cover 18 around which the straightening roller 17 is mounted is swingable by a shaft 19, and the distance between the straightening conveyor 10 and the straightening roller 17 can be adjusted by turning a screw 20 screwed into the base end of the cover. . Reference numeral 21 denotes a spring that urges the cover 18 to close, and is provided in the middle of the cover 18. The shaft 19 is provided on the tip of the cover 18 near the flow straightening roller 17, and the screw 20 is attached to the cover 18.
It is provided at the base end of and is attached to the frame of the conveyor 4. Then, by tightening the screw 20, the base end of the cover 18 is lowered, and the rectifying roller 17 is raised as its reaction force. Further, by loosening the screw 20, the base end of the cover 18 goes up and the rectifying roller 17 goes down. Here, the straightening roller shaft and the shaft 19
Since the distance from the straightening roller shaft to the screw 20 is longer than the distance between and, fine adjustment can be performed with a slight force. Therefore, a guide 22 is provided on the exit side 15 of the rectifying conveyor 10, and a drive motor 23 is arranged above the guide 22.

As shown in FIG. 2, a sprocket 25 is attached to a drive shaft 24 of a drive motor 23, and a sprocket 26 is attached to a drive roller 11 of the rectifying conveyor 10.
The power of the drive motor 23 is transmitted via the chain 27. The rotation of the drive roller 11 is transmitted to the rectifying roller 17 via the sprocket 28, the chain 29, and the sprocket 30. Further, the rotation of the drive roller 11 is transmitted to the drive roller 31 of the conveyor 4 via the sprocket 32, the chain 33, and the sprocket 34. With the above power transmission mechanism, each roller rotates counterclockwise in FIG.

In the rectifying device of the embodiment of the present invention having the above construction, the coin a discharged from each ball lending machine 3 is conveyed to the end by the conveyor 4 in the pachinko island 1 and drops, It is supplied to the inlet side 13 of the rectifying conveyor 10. In this way, the coin a supplied to the straightening conveyor 10 in a lying state is sequentially moved to the exit side 15 by the circumferential movement of the straightening conveyor 10, and in the middle thereof, the straightening roller 1
The sheets are rectified in 7 and discharged one by one from the end of the rectifying conveyor 10. In addition, as shown in a ', the rectifying conveyor 1
The coins supplied while standing on the entrance side 13 of 0 do not move to the exit side due to the inclination of the rectifying conveyor 10 and the stopper 14, and temporarily stop at the conveyor entrance side 13. It will be in a closed state, but the conveyor 4
The coins a which are successively supplied from one another collide with each other and are eventually toppled, and the stopper 14 prevents the coins from dropping through the gap between the two conveyors. In this manner, the rectifying conveyor 10 is laid down and moves to the exit side 15 by the circular movement of the rectifying conveyor 10, is rectified by the rectifying roller 17 in the middle thereof, and is discharged one by one from the end of the rectifying conveyor 10. The coins a discharged from the end of the rectifying conveyor 10 are transferred to the guide 22 and fall, and the sensor 7 accurately detects the coins one by one during the fall.

However, the present invention is not limited to the above-mentioned embodiments, and other than coins such as metal for games,
The same can be applied to a rectifying device such as a coin.
When coins a are dropped from the end of the transport conveyor 4 to the entry side 13 of the rectifying conveyor 10 and supplied as in the embodiment, the shock of the fall is used to transfer coins a.
Is more convenient because it can be laid down sideways, and the coin a can be stored in the inlet side 13 of the rectifying conveyor 10 by utilizing the drop between the outlet side of the conveyor 4 and the inlet side of the rectifying conveyor 10. It has the feature that the stock volume can be increased.

[0011]

[Effects of the Invention] In any of the above, in the rectifying device for coins or the like of the present invention, the supplied coins or the like are laid down sideways by a stopper, and a rectifying conveyor and a rectifying roller having an inclination are provided. Since the coins can be surely rectified through and discharged one by one, coins in a standing state do not collect in front of the rectifying roller and a counting error does not occur. Therefore, it becomes easy to manage at a pachinko parlor and the like, and the work efficiency can be improved.
Further, since the stopper prevents coins from dropping from the gap between the transport conveyor and the rectifying conveyor, the coins stop at the inlet side of the rectifying conveyor, with the slanting of the rectifying conveyor. The coins, which are successively supplied from the conveyor, collide with each other and fall down, and the sideways action is doubled. Furthermore, since the rectifying roller corresponding to the rectifying conveyor is pivotally mounted on the swingable cover, the distance between the rectifying conveyor and the rectifying conveyor can be adjusted, the rectifying effect can be improved, and the screw at the base end can be used with the tip axis as a fulcrum. The cover can be swung freely, and the straightening roller is mounted on the tip of the cover so that it can be adjusted with a slight force. Further, since the cover also serves as the adjusting mechanism of the flow straightening roller, it is not necessary to provide another adjusting mechanism, and the device can be formed compactly. Furthermore, since the transport conveyor and the rectification device are separate components, there is a feature that maintenance is easy.
