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

摘要

By adopting a workpiece transfer apparatus, which grips a workpiece by use of a predetermined grip device and transfers the workpiece between press apparatuses each of which drives a die, including a transfer control device for controlling a position of the grip device based on a resultant target value obtained by combining a die position of a press apparatus located on an upstream side of a workpiece transfer direction (an upstream side die position) and a die position of a press apparatus located on a downstream side of a workpiece transfer direction (a downstream side die position), in which the transfer control device sets a resultant target value so that the grip device moves smoothly, it becomes possible to suppress vibration in a workpiece transfer apparatus in a press line.
