In a CLOOS robot system the industrial vehicle specialist Junton welds smaller attached parts and accessories for tippers. Five QIROX robots type QRC-350 weld more than 60 different workpiece versions. The focus of the system is on an intelligent shuttle system which automatically distributes the workpieces with the fixtures to the different welding robots. The shuttle in the loading area recognises automatically to which welding station the workpiece is sent. The welding robot also identifies from the jig which welding program to use for the component. The shuttle is equipped with a double gripper that allows a nearly simultaneous loading and unloading of the components. The CLOOS system enabled Junton to significantly improve both the quality of the production processes and the work environment and to increase the repeatability.
