Description

Technical Field

[0001] The present invention relates to the technical field of logistics equipment, and in particular to a traction drive device for a multi-layer sorting machine and a control method thereof. Background Art

[0002] Sorting machines are often used in the field of logistics equipment. Common sorting machines use tracks and a vehicle body that can move on the track through a drive device. Users place goods on the vehicle body, and the vehicle body moves along the guide rails to deliver the goods on the vehicle body to the designated location. There are also higher requirements for the efficiency of the sorting system, which requires the sorting system to be faster, more efficient, stable and reliable in operation, and lower in energy consumption. Some manufacturers also use double-layer sorting devices, including conveyor line 1 and conveyor line 2, at different heights in the vertical direction to increase sorting efficiency. However, such a structure requires the manufacturer to set up two conveyor lines and equip them with sliding plates to guide the goods into different conveyor lines, which is costly.

[0003] With the continuous increase in the volume of logistics and express delivery business, various express delivery companies have urgently proposed to improve the sorting efficiency of sorting machines and increase the number of sorting slots. Therefore, each sorting center has gradually configured double-layer, three-layer and four-layer sorting machine equipment from single-layer sorting machine equipment. For example, patent publication number CN105035673A proposes a conjoined double-layer cross-belt sorting machine, which connects the trolleys to each other through cantilever support rods. When the trolleys are connected in series into a ring, each trolley will have a support rod. The support rod reduces the load area of ​​the tray, which is easy to block the sorted items, increase the difficulty of loading, and affect the accuracy of loading.

[0004] Another example is the patent publication number CN110817305A double-layer cross-belt sorting equipment and the patent publication number CN 110861882A a multi-track sorting trolley conveying mechanism. A driving method of using multiple cantilever support rods connected to the lower trolley to push the upper line body is proposed. When the lower line body pushes the upper line body through the cantilever support rod, the upper end of the support rod is subjected to the reaction force of the upper line body, causing the lower line body to bear the torque along the loop line, causing the vertical wheel of the lower trolley to bear greater pressure and the other end to warp. Summary of the invention
