[0016] The present invention will be described in detail below with reference to the accompanying drawings.

[0017] Embodiment 1:

[0018] The following is combined with Figure 1 The present embodiment describes a device for detecting missing tablets of a medicine plate, comprising: a main conveyor 1, both sides of the main conveyor 1 are supported by a conveying bracket 2, a tray 3 is provided at the lower part of the conveying end of the main conveyor 1, a quality sensor is connected to the lower part of the tray 3, two groups of sorting conveyors 4 are provided on both sides of the tray 3, the sorting conveyor 4 is supported by a conveying bracket 5, the conveying bracket 5 on one side of the tray 3 is flush with the upper surface of the tray 3, and the conveying bracket 5 on the other side is higher than the upper surface of the tray 3, the conveying bracket 5 on this side is connected with an air duct 6, and the blower blows air to the tray 3 through the air duct 6, the quality sensor can send a quality signal to the controller, and the controller determines which of the air ducts 6 on both sides is out of the air according to the quality signal;

[0019] The medicine plates are discharged to the main conveyor 1, and the main conveyor 1 conveys the medicine plates to the tray 3. The quality sensor detects the quality of the medicine plates and sends the quality signal to the controller. When the quality of the medicine plates is greater than or equal to the standard quality, the controller controls the blower to discharge air from the air duct 6 on one side, and blow the medicine plates to the sorting conveyor 4 on the other side. When the quality of the medicine plates is less than the standard quality and greater than 0, the air duct 6 on the other side discharges air, and blows the medicine plates to the opposite sorting conveyor 4 to complete the sorting. When the weighing quality is 0, no air is discharged, and the sorting is completed without considering the placement position, angle, front and back of the medicine plates.

[0020] The roller ends on both sides of the main conveyor 1 are connected to the roller ends of the sorting conveyor 4 through a belt drive 7;

[0021] The main conveyor 1 provides power for the two sorting conveyors 4, which saves cost and enables simultaneous start and close.

[0022] The conveying support 1-2 of the main conveyor 1 is higher than the upper surface of the conveyor belt, and a baffle 8 is provided on the upper surface of the conveyor belt with a gap, the gap height is not greater than the thickness of two medicine plates and not less than the thickness of one medicine plate, and the baffle 8 is connected to the conveying support 1-2;

[0023] The baffle can effectively prevent the medicine plates from stacking.

[0024] The baffle 8 is located at the conveying end of the main conveyor 1. The side of the end of the baffle 8 is connected to the second air duct 10 through the pipe rack 9. The second air duct 10 is tilted and directly hits the gap at the bottom of the baffle 8. The second air duct 10 is connected to the blower. The controller determines whether the second air duct 10 is discharging air according to the quality signal.

[0025] When the weighed mass is greater than the mass of a medicine plate, the controller controls the air duct 2 10 through the blower to keep the air flowing out, and the air flows directly into the gap below the baffle 8 to block the subsequent medicine plate transportation.
