Abstract
A press system and a control method of the press system that can automatically set a timing for coordinating a press machine and a feeding device. A leveler feeder includes feed rolls that convey a coil material to the press machine in a closed state in which the coil material is clamped, and are brought into an open state in which the coil material is released when stamping by the press machine is started. The press machine includes a sensor for detecting a load F at a time of the stamping, a pilot pin that is inserted into a hole pierced in the coil material for positioning at a time of the stamping, and a controller for controlling the leveler feeder and the press machine so as to perform the stamping in coordination with each other. The controller determines a release start timing Tos (a position Ps+L) at which the feed rolls are switched from the closed state to the open state based on a result of detecting by the sensor as well as a length L of the pilot pin.
