In the existing logistics sorting equipment, the main structural forms include cross-belt type, slider type sorting and rotor type sorting. The rotor type sorting has the characteristics of small occupied space, flexible installation form and high sorting efficiency, and is widely used in the express industry.

[0003] In the rotor type sorting device, the goods are conveyed by multiple rotor units, referring to Figure 2 Each modular rotor unit can turn. The rotor type sorting device is mainly divided into roller type, electric roller type and belt type according to the structure of the conveying mechanism. The roller type sorting usually adopts a motor to drive the main shaft to rotate, and an O-shaped belt obtains power transmission to the roller to rotate and convey. After long-term operation, the O-shaped belt is aged and relaxed, causing slip and wear, low transmission efficiency, and even running out of the roller groove. The conventional electric roller type sorting usually adopts a brushless direct drive motor to provide power to drive the roller to convey. Its structure is flexible and has many combination styles, but in the conveying process, the electric roller has limited carrying capacity. When conveying heavy packages, the motor overload fault alarm is triggered. SUMMARY
