Abstract

PURPOSE: To improve safety at the time of operating a press by checking trouble in a light-ray type safety device before the start of operation of the press.
CONSTITUTION: In operating a press device, by the operation of a plurality of operational buttons, the corresponding required relays are operated. By this, output Q of flip-flop circuit F/F becomes high level and trouble checking is started by light- emitting elements 2a to 2d and light-receiving elements 4a to 4d. When light-emitting elements 2a to 2d and light-receiving elements 4a to 4d operate normally and a series of trouble checking operations are completed, the output of emergency stop signal generating circuit 6 becomes high level; and relay coil 7 is energized and the contact is closed. By this, the required relays are actuated, and the operation of the press is started. When any of light-emitting elements 2a to 2d and light-receiving elements 4a to 4d fails, the output of emergency stop signal generating circuit 6 does not become high level, and the subsequent operations are stopped.
