The reverse - side chute 27 is arranged on the side away from the coin queue. An air nozzle is also provided on the first belt conveyor 21. The air nozzle is arranged behind the identification camera, and baffles are symmetrically arranged on both sides of the air nozzle to prevent the coins from being blown off the belt during the conveying process. When the reverse - side identification part 25 identifies that the reverse side of the coin is facing up, the coin can move perpendicular to its transmission direction on the surface of the first belt conveyor 21 under the blowing force of the air nozzle, move to one side of the reverse - side chute 27, and then move along it to the reverse - side chute 27 for turning over under the action of the inclined coin - arranging rod 28. Both the coin - arranging rod 24 and the inclined coin - arranging rod 28 are fixed above the belt through mounting brackets and have a gap with the belt surface to avoid causing friction and damage to it. Moreover, their positions and inclinations on the mounting brackets can be adjusted to limit the trajectory of the coins. A coin collection box 29 is arranged on one side of the intersection of the coin - arranging rods 24 arranged in a figure - eight shape to prevent the coins from piling up at the queue where the trajectory changes and falling off the belt. The coins sliding out of the belt can be collected in each coin collection box 29.

[0040] In this embodiment, the normal chute 26 is a curved chute. The normal chute 26 is a curved chute with a gradually decreasing height.

The inner side of the reverse - side chute 27 faces the first belt conveyor 21. The top of the semi - circular arc chute is connected to the end of the first belt conveyor 21, and it is slightly higher than the surface of the first belt conveyor 21 to allow the coins to enter. The bottom of the semi - circular arc chute is connected to the surface of the second belt conveyor 22. The coins with the reverse side facing up smoothly pass through the semi - circular arc chute and then land on the surface of the second belt conveyor 22 with the front side facing up and flow, and are conveyed in a queue with other coins sliding down from the normal chute 26 under the action of the coin - arranging rod 24.

[0041] As Figure 1 、 3As shown in the figure, the height of the first glass turntable conveying part 3 is higher than that of the second glass turntable conveying part 5. A front vision detection and sorting part 8 is arranged on the first glass turntable conveying part 3.

The coins that pass the detection are turned over by the secondary turning and conveying part 4 and then conveyed to the second glass turntable conveying part 5. A reverse vision detection and sorting part 9 is arranged on the second glass turntable conveying part 5. The reverse vision detection and sorting part 9 is used for visually detecting the reverse side of the coins that are qualified on the front side. Among them, the layout of the front vision detection and sorting part 8 on the first glass turntable conveying part 3 is the same as that of the reverse vision detection and sorting part 9 on the second glass turntable conveying part 5, and their structures are correspondingly the same. Now, taking the front vision detection and sorting part 8 and the first glass turntable conveying part 3 as examples, their structures will be specifically described. An installation disk 31 arranged coaxially with it is provided above the first glass turntable conveying part 3. The first glass turntable conveying part 3 and the installation disk 31 can rotate driven by a rotating shaft 32. Among them, the diameter of the installation disk 31 is smaller than that of the first glass turntable conveying part 3. A plurality of installation stations 33 are arranged on the edge of the installation disk 31.

The turning baffle 42 is in a semi-circular arc shape and is arranged at the end of the third belt conveyor 41 and its bottom is connected to the head end of the fourth belt conveyor 43. After the coin queue with the front side facing up flows onto the surface of the first glass turntable conveying section 3, under the limitation of the coin sorting structure, it gradually moves to each station for various item detections. After the detection is completed, the good coins without any defects flow into the third belt conveyor 41, are turned over by the turning baffle 42, and then are conveyed to the second glass turntable conveying section 5 through the fourth belt conveyor 43. They pass through each detection station of the reverse vision detection and sorting section 9 in sequence for various index detections. The good coins without defects on both the front and back sides after being detected by the front vision detection and sorting section 8 and the reverse vision detection and sorting section 9 are conveyed to the discharging and sorting section 6.
