With the continuous development of the logistics industry, people use express delivery more frequently, which has greatly promoted the development of the logistics industry. With the increase in express delivery, the types of express delivery have also increased, and there will be express deliveries of different weights, and the transportation costs of express deliveries of different weights will also be different.

[0003] The existing express sorting process is completed manually. Most logistics conveying devices can only transmit the express, and the express items need to be sorted multiple times by size and weight.

[0033] Specifically, the express items are transferred to the delivery air cushion plate 1015 through the pushing plate 905, and the express items exert pressure on the delivery air cushion plate 1015, causing the delivery air cushion plate 1015 to shrink downward, and the gas in the delivery air cushion plate 1015 enters the expansion air bag 1018 through the second air pipe 1017, causing the expansion air bag 1018 to expand. The expanded expansion air bag 1018 is located around the express items to prevent the express items from falling during the weight sorting process, thereby improving the sorting effect.

[0034] Working principle: When sorting express items, the express items are placed on the conveyor belt 4, and the driving motor 3 drives the conveyor belt 4. The express items are transported by the conveyor belt 4. According to the sorting needs of the express items, the first stepper motor 802 drives the first threaded rod 803 to rotate, so that the height of the lifting support 804 changes, and then the height of the express item baffle 805 is adjusted.

The height of the express item is higher than the express item baffle 805 at the corresponding position. 05, the express item contacts the express item baffle 805, and the express items of different heights are sorted out. The express items sorted by the express item baffle 805 contact the contact sensor 806. After the contact sensor 806 contacts the express item, it transmits a signal to the controller. The controller controls the second stepper motor 901 to rotate the second threaded rod 902, and the moving seat 903 moves along the surface of the second threaded rod 902, and the push plate 905 moves accordingly. When the fixed suction cup 908 contacts the express item, the air pump 906 moves the fixed suction cup 908 through the first air pipe 907. The gas inside 8 is extracted to form a negative pressure between the fixed suction cup 908 and the express item, so as to prevent the express item from falling during the transfer process or failing to be transferred due to position deviation, so as to realize the transfer of the express items after high sorting, and transfer the express items to the delivery air cushion board 1015 through the push plate 905. The express items exert pressure on the delivery air cushion board 1015, so that the delivery air cushion board 1015 shrinks downward, and the gas in the delivery air cushion board 1015 enters the expansion air bag 1018 through the second air pipe 1017, so that the expansion air bag 1018 expands. The expanded expansion air bag 1018 is in The express items are prevented from falling during the weight sorting process and the sorting effect is improved. According to the different weights of the express items, the tensioning spring 1014 is compressed to different degrees, so that the transfer base plate 1013 is lowered to different heights. After the height of the transfer base plate 1013 does not change, the flip motor 1020 is controlled to drive the fixed rotating rod 1019 to rotate, and then the delivery air cushion plate 1015 is flipped upward, so that the express items on the delivery air cushion plate 1015 fall to the corresponding position, thereby realizing the sorting of express items of different weights, improving the sorting efficiency of express items and reducing the labor intensity of staff.
