Abstract: In order to solve problems of complex structure and high cost of existing handling system, the paper proposed a design scheme of small-scale automatic handling system. The system uses supports and ropes to handing goods through control mode of multi-computer network, and uses interpolation algorithm to set or optimize handling paths. The system realizes functions of sorting inbound, palletizing and distributing outbound through manual mode, semi-automatic mode or automatic mode. The debugging and running results showed that the system realizes expected functions perfectly.
