Abstract
PURPOSE: To control the laminated thickness in high accuracy, using the ordinary contactless sensor of low accuracy, by detecting the marked iron core sheet with the contactless sensor, and by computing the average sheet thickness.
CONSTITUTION: The length L, from the entrance of the laminated iron core sheet on the lower die in the fourth stantion to the center line of the contactless sensor 15, is previously memorized by the control unit 17. The output of the sensor 15 is inputted to the control unit 17 through the A-D converter 18, and hereby, the distance l between the center line of the sensor 15 and that of the iron core sheet 16 is obtained. Meanwhile, the number N of the laminated iron core sheets B, being laminated upon the iron core sheet 16, is equal to the number of the iron core sheets piled up after actuating the solenoid 12 for marking the hole; this number N is discriminated by the control unit 17 by counting the signal of the microswitch 6. Accordingly, the average thickness ta of N iron core sheets is computed according to the formula ta=(L+l)/(N-0.5).
