The sorting line for finished welding wire is 460 meters in length, for which 6 truss sorting robots are arranged with the adoption of the rack free control system. Also, the peak production volume of the production line can be satisfied with the optimized cycle design using the multi-machine joint operation method. The upper computer performs unified scheduling and command on safety protection among multiple robots with the shared system position coordinates.

The rack free control system is adopted, which is composed of 1 rectifier module, 1 control module, and 1 one-to-four driver. There is neither a control cabinet nor wiring construction.
