Abstract
PURPOSE: To increase reliability in predicting disorders with a simple device by detecting the necessary time for a movable part to move for a fixed distance.
CONSTITUTION: Limit switches 12W15 are set at moving ends of a cylinder 11 moved by a cylinder 10 and of a head 16 moved by a cylinder 11, and they are connected to a disorder-predicting device 1 through a sequence control circuit 7. Thus, according to the change-over signal of electromagnetic valves 8, 9 from the sequence control circuit 7 and the detecting signals of each limit switch at the cylinder 11 and the head 16, a detector circuit 3 detects the time required between the operation starting signal of the cylinder 11 and the head 16 and the signal detected at a moving groove. The time thus required is compared with the standard time of the fixed circuit 2 at a comparing circuit 4, which result is judged at a judging circuit 5 and indicated at an indicating circuit 6, thus a disorder at a machining device 17 is predicted.
