Abstract
PURPOSE: To detect easily abnormal states or troubles arised at any crank angle by providing a circuit which compares a control information at normal operation memorized beforehand with a control information detected at the working operation of a press.
CONSTITUTION: An angle detector 2 detecting a crank angle is equipped to a press main body 1 to generate a clock signal at every position of a define datum angle. This signal is input to a detecting angle setting part 3, an address setting part 4, and a writing signal generating circuit 5. The address setting part 4, upon writing an information at normal operation outputs an address at every datum angle due to the clock signal to a memory part 8. And also the angle detecting troubles is set in the detecting angle setting part 3. An information writing executing signal 9 at normal operation is input to the write signal generating circuit 5, and an information write signal 10 at every datum angle is output to the memory part 8. A memorized information 10' at normal operation is input together with a control information 11 detected at the working time into a comparator 6, so that a trouble signal 12 will be output in a case of trouble.
