                    The industrial vehicle specialist Henan Junton Vehicle welds crane supports and smaller rotating towers with a highly complex chained system. The system consists of four QIROX QRC-410-E welding robots and a storage system. The fixtures are manually loaded. Then the employee scans the bar code at the fixture and it is temporarily stored in the storage system. As soon as the appropriate welding robot is available, a carriage placed on a floor-mounted linear track gets the workpiece and takes it to the welding station. After welding, the carriage picks up the workpiece again and temporarily stores it for cooling down. When the component is cold, it is automatically brought to the unloading station. After unloading, the empty fixture is transported back to the temporary storage. Due to the automated logistics solutions, errors because of a wrong component allocation can be avoided completely. Thus Junton saves much time, space and costs. Furthermore, the cycle times were considerably reduced.
