Workpiece changing system

摘要

A workpiece changing system capable of automatically changing a heavy workpiece using a robot. A jig for attaching a workpiece thereto is mounted on a jig mounting device. The jig mounting device comprises a jig mounting unit having a rotary member and a swing member. The rotary member rotates the jig and the workpiece on the jig and hold them at a desired rotary position. The tilting member swings around an axis to tilt the jig and the workpiece on the jig and hold them at a desired tilting position. As the jig and the workpiece on the jig can take a suitable orientation or posture for being handled by the handling robot, the handling robot can hold a heavy workpiece without exerting excessive load on the robot wrist.
