<p>PROBLEM TO BE SOLVED: To eliminate application of an actuator for a number of jig plates which move to rotate, reduce a failure rate, and improve productivity. SOLUTION: Plural work positioning jigs 13-18 to be selectively used in accordance with sorts of works are installed on respective jig plates 11. Each jig plate 11 is synchronously run with a jig changing unit 12 between a jig changing starting stage S1 in a prestage of a work charging stage S3 and a jig changing completing stage S2. In synchronous run of them, selective change of the work positioning jigs 13-18 is performed by the jig changing unit 12 in accordance with work sort information provided from a host production indication device. The work positioning jigs 13-18 are of such a constitution that can be manually operated, and in case of failure of the jig changing unit 12, they are selectively changed by manual operation.</p> |
