Servo transfer feeder and control method of servo transfer feeder

摘要

A servo transfer feeder is configured to transfer a workpiece that is held by a holding member between an upstream press and a downstream press, and includes a storage section that stores a basic cam curve, a maximum velocity, and a maximum acceleration, a moving time calculation section that respectively calculates different moving times as to the moving distance of the holding member by limiting the basic cam curve respectively to the maximum velocity and the maximum acceleration, and a cam curve generation section that generates a motion cam curve by reflecting the moving distance and a longer one of the different moving times to the basic cam curve. The holding member moves between the upstream press and the downstream press, based on the motion cam curve.
