Operation apparatus for press

Abstract

The present invention provides an operation apparatus for a press, of simple structure with lower cost. The operation apparatus for a press according to the present invention comprises a controlling system 1 for generating a slide actuation command signal K1 by an ON operation of an operation button or an entrance/escape detection output of a human body by a light-beam type safety apparatus and controlling slide actuation, based on a crank angle signal from an encoder 4; a monitoring system 2 for monitoring controlling operation of the controlling system 1, including slide overrun monitoring function and the like, utilizing operation button ON signal T, operation button-OFF signal /T or the detection output from the light-beam type safety apparatus, position signals Pa and Pb indicative of slide elevating process and slide lowering process, respectively, position signal Ph from a light-beam type safety apparatus, and slide actuation command OFF signal /K1; and an AND gate 3 for generating a slide actuation signal S based on the slide actuation command signal K1 from the controlling system 1, only when the normality judgment signals K2, K3 are being generated from the monitoring system 2.
