ABSTRACT:
A misgrip detection control system for detecting unholding or misgrip of a workpiece from a transfer bar in a press.
The system comprises a workpiece memory circuit for storing electrically data indicating whether a workpiece is in position of a corresponding station in the press or not, a workpiece presence/absence checking circuit for detecting the presence or absence of the respective said workpiece by sensors mounted in transfer bars and a misgrip detecting circuit for detecting misgrip of the workpiece by comparison of data from said both circuits.
In one preferred embodiment, all of said circuits are constructed by relays.
