Abstract

PURPOSE:To improve safety and enable reduction of labor and unattended operation by performing control basing on confirmation signals for important items necessary for safe operation in controlling device of a press. CONSTITUTION:An operation permissin interlock circuit L is operated to perform safety operation of a press by output of a logical product circuit A that receives safety confirmation signals of safety confirming items C1-C8 including inching check, safety stroke check, emergency stop check, restarting prevention check etc. At the same time, safety confirmation signals of safety confirming items C1-C8 are reset, and signals of every cycle during continuous operation and safety confirmation signals of each safety confirming item C1-C8 are inputted to a logical product circuit A. Output of the logical product circuit A is inputted to a monitoring circuit M2. A press controlling circuit P is controlled by the monitoring circuit M2 during operation.
