The flipping component includes a fixing plate 13, a fixing rod 14, a guiding block 15, a third telescopic device 16, a connecting block 17, a moving rod 18 and a moving component.

[0031] The moving component includes a rotating roller 19, a conveyor belt 20, a support shaft 21, rollers 22, a driving gear 23 and a driven gear 24.

The baffles 25 are connected to the guiding blocks 15 through dovetail blocks and dovetail grooves formed in the guiding blocks 15, so as to classify express boxes of different volumes.

[0033] In summary, when the utility model is in use, the express box containing drugs or medical supplies is placed on the belt conveyor 2 after being pasted with a barcode by a machine or manually. It gradually comes into contact with the guide plate 11 during the conveyance of the belt conveyor 2, and gradually moves to the middle position of the belt conveyor 2 under the guidance of the guide plate 11. At the same time, it will come into contact with the cleaning roller 12 connected to the guide plate 11 to clean its surface. The position of the guide plate 11 can be adjusted by the second telescopic device 10 to change its spacing to adapt to express boxes of different sizes. After being guided, the express box enters the first scanning assembly. The three sides of the express box are scanned by the first scanning device 5 and the second scanning device 8 to identify the barcode on its surface. The movement of the mobile ends of the first telescopic device 3 and the double-headed double-out cylinder 6 drives the moving block 7 and the top plate 4 to move, changing the distance between the first scanning device 5 and the second scanning device 8 and the express box to make it at a more appropriate scanning distance. After the express box passes through the upstream scanning assembly, the express box is conveyed by the belt conveyor 2 and enters above the guide block 15. The roller 22 comes into contact with the conveyor belt on the belt conveyor 2 and is driven to rotate. The rotation of the driving gear 23 is driven through the connection of the support shaft 21. The driving gear 23 meshes with the driven gear 24, thereby driving the rotating roller 19 to rotate, making the conveyor belt 20 rotate in the same direction as the conveyor belt on the belt conveyor 2. The express box gradually moves from low to high and then drops to generate a flip to prevent the barcode from being blocked. According to the different sizes of the express box, the telescopic end of the third telescopic device 16 moves to drive the connecting block 17 and the moving rod 18 to move, so that it rotates around the fixed rod 14 to adjust its angle and further adjust the height of the high part of the guide rod 14. The express box is scanned twice by the downstream scanning assembly to complete the barcode scanning work. If the barcode of the express box is blocked after being reversed after the barcode scanning is completed by the previous scanning assembly, or if the barcode of the express box is blocked by the previous scanning assembly, it will be scanned by the downstream scanning assembly through the flipping assembly. The second scanning device 8 in the horizontal direction can also perform scanning, avoiding the problem that the first scanning device 5 at the top cannot scan due to the barcode being pasted at different positions.

[0034] The embodiments of the utility model have been described in detail above in conjunction with the accompanying drawings. However, the utility model is not limited thereto. Various changes can be made without departing from the spirit of the utility model within the scope of knowledge possessed by those skilled in the art to which the utility model pertains.
