WORKPIECE TRANSFER APPARATUS, CONTROL METHOD FOR WORKPIECE TRANSFER APPARATUS, AND PRESS LINE

摘要

A work conveying device holding a work by using a prescribed holding means between press devices where molds are driven and conveying the work. The work conveying device comprises a conveyance control means controlling the position of the holding means based on a target synthetic value obtained by synthesizing the mold position of the press device positioned on the upstream side in a work conveying direction (upstream side mold position) and the mold position of the press device positioned on the downstream side (downstream side mold position). The conveyance control means can suppress the vibration of the work conveying device in a press line by adopting a means for setting the target synthetic value so that the holding means can be smoothly moved.
