When the sorting system sorts the goods, the sorting system determines a transmission route according to the starting position and the end position of the goods, and determines the sorting equipment 100 on the transmission line and the transmission direction of each sorting equipment 100 on the transmission line. The sorting apparatuses 100 then adjust the conveying direction by controlling the corresponding sorting apparatus 100 and sequentially convey the goods.

As shown in fig. 2, the transferring device 130 includes a bracket 131 and a transferring mechanism 132, and the transferring mechanism 132 is mounted on the bracket 131 for receiving the goods and transferring the goods thereon. The transmission mechanism 132 includes a plurality of transmission assemblies 1320 arranged side by side, each transmission assembly 1320 includes a transmission belt 1321 and a supporting structure 1322 for supporting the transmission belt 1321, and the supporting structure 1322 is connected with the bracket 131 so that the transmission mechanism 132 is installed on the bracket 131.

The conveying device 130 further comprises a tensioning mechanism 136, wherein the tensioning mechanism 136 is arranged on the bracket 131 and used for abutting against the rollers of the conveying belts 1321 of the plurality of conveying assemblies 1320 so as to tension the conveying belts 1321 of the plurality of conveying assemblies 1320, so that the conveying belts 1321 of the plurality of conveying assemblies 1320 run more stably, slipping and the like are not easy to occur, and goods on the conveying belts can be stably conveyed.

When the first driving structure 1368 drives the two first sliding members 1366 to slide in the same direction, the first mounting frame 1365 can be driven to slide integrally relative to the bracket 131, so as to drive the tensioning roller 1361 to slide together relative to the bracket 131.

Optionally, the first driving structure 1368 includes a first screw 1369 rotatably connected to the bracket 131, and a length direction of the first screw 1369 forms an angle with a transmission direction of the transmission assembly 1320 and a distribution direction of the transmission assemblies 1320. A first threaded hole adapted to the first screw 1369 is formed in the first sliding member 1366, and the first screw 1369 is inserted into the first threaded hole and is in threaded connection with the first sliding member 1366. By rotating the first screw 1369 relative to the first slider 1366, the first slider 1366 can be slid in the longitudinal direction of the first screw 1369, thereby more conveniently sliding the tension roller 1361.

It should be noted that both the two first sliding members 1366 may be driven by different first screws 1369, one of the first sliding members 1366 may be driven by the first screw 1369, and the other of the first sliding members 1366 may be driven by a telescopic structure such as an air cylinder or a hydraulic cylinder, and of course, the former may facilitate adjustment of the two first sliding members 1366 that slide the same distance.
