Description

Technical Field

[0001] The invention relates to a sorting device, belonging to the technical field of logistics equipment. Background Art

[0002] The logistics industry developed relatively late, and many of them are still mainly sorted by hand. The main characteristics of the existing sorting industry are low automation and limited application of sorting equipment. There are still many problems to be overcome in the current express delivery industry to achieve automation, such as:

[0003] (1) The construction speed of large-scale sorting centers is slow. Since the sorting equipment in large centers is expensive, many express delivery companies are small and cannot afford the high prices.

[0016] The working principle of the present invention is:

[0017] The present invention is composed of a scanning mechanism, a transmission mechanism, an actuator, and a sorting mechanism. Due to the advantages of the relatively simple structure, small footprint, and low cost of the sorting machine, it is suitable for small and medium-sized enterprises in my country's express delivery industry. The scanning mechanism of the sorting machine mainly uses the mature two-dimensional code scanner for scanning. The two-dimensional code scanner has the advantages of fast scanning speed, which can be completed in about 0.1 seconds, and low scanning error rate. The two-dimensional code scanner is installed on the frame of the transmission mechanism. When the goods are placed on the transmission mechanism, the conveyor belt sends the goods to the two-dimensional code scanner for scanning; the transmission mechanism mainly uses a conveyor belt for transmission, and according to the required transmission speed, the motor is decelerated by using a secondary reducer to achieve the expected transmission speed; the actuator adopts a crank slider mechanism. When the goods run to the specified position, the mechanism starts to work and pushes the goods to the sorting port for sorting. When the goods arrive at the sorting port, the sorting mechanism manipulator starts to work and sends the goods to the next sorting port or the mechanism for loading goods to complete the mobile sorting of the goods.

[0018] The present invention connects the main motor 24 to the high-speed shaft of the secondary reducer 23 through a coupling, and the motor is decelerated by the reducer so that its low-speed shaft outputs a relatively low speed; the low-speed shaft of the reducer is connected to the active roller 25 through a pulley, so that the active roller 25 rotates and transmits the speed to the active roller. The rotation of the active roller 25 realizes the transmission of the conveyor belt 2. Since the conveyor belt 2 is connected to the driven roller 22, when the conveyor belt 2 moves, the driven roller 22 realizes synchronous rotation.

[0019] When the push rod motor 11 rotates, it drives the small bevel gear 28 to rotate. The small bevel gear 28 cooperates with the large bevel gear 29, thereby driving the movement of the large bevel gear 29. Due to the mutual meshing of the small bevel gear 28 and the large bevel gear 29, the movement of the large bevel gear 29 is driven. Since the large bevel gear 29 is coaxially connected to the large gear 9 through the shaft, the small gear 10 meshes with the large gear 9, the large gear 9 drives the small gear 10 to rotate, and the small gear 10 rotates coaxially with the gear sleeve 7. The gear sleeve 7 drives the connecting rod 12 to reciprocate through the rotation movement, and the rear half of the bearing sleeve 7 is connected to the push rod bracket 8 through the shaft, so when the two gears move, the bearing sleeve will be driven to move around the push rod bracket 8. The connecting rod 12 is connected to the push rod 13, so when the bearing sleeve 7 moves, it will drive the connecting rod 12 to move and thus drive the movement of the push rod 13. Since the push rod 12 can only move forward and backward in the push rod sleeve 14, when the motor rotates, through a series of transmissions, the push rod 13 can achieve the pushing effect of the goods.

[0020] When the goods are about to arrive at the sorting place, the horizontal motor 20 of the manipulator rotates, driving the long threaded rod 6 to rotate through the coupling. Since one side of the manipulator arm is connected to the long threaded rod 6 through the threaded hole at the bottom end of the mechanical claw fixing block 16, when the long threaded rod 6 rotates, it will drive the manipulator arm to move along the long threaded rod 6. The vertical motor 30 of the mechanical claw rotates, driving the short threaded rod 31 to rotate through the coupling 19. Since the short threaded rod 31 cooperates with the threaded hole of the moving block 17 and is fixed to the moving block 17 by a nut, when the short threaded rod 31 rotates, it will drive the moving block 17 to move forward and backward. The moving block 17 is connected to the connecting rod 15, and the connecting rod 15 is connected to the mechanical claw 4. When the moving block 17 moves forward and backward, the mechanical claw 4 is driven to move through the action of the connecting rod 15, so that the mechanical claw opens and closes to perform a grabbing action, thereby performing mobile sorting.

[0021] The beneficial effects of the present invention are as follows: compared with existing products, the present invention has the advantages of low cost, simple and convenient maintenance, etc., and is easy to promote. It is convenient to use and has high efficiency, which is conducive to the introduction and development of sorting equipment for small and medium-sized enterprises in the express sorting industry.
