Title: Terminal detecting device for plate material
Inventor: ONARI HIROSHI
IPC: G01V9/00
Filed: 1986-05-27
Abstract: PURPOSE:To accurately detect a terminal of a plate material by detecting the quantity and direction of movement of a roller when a plate material to be conveyed is supplied to a pinch roller. CONSTITUTION:The plate material 3 is conveyed on a roller 1, its front end contacts the pinch roller 7, and the material is moved up while pushing up the roller 7. Then, contacting ends of touch sensors 15 and 17 send out signals by being pressed by a shaft 9 and the front end of the plate material 3 is detected. Further, the plate material 3 is conveyed on the roller 1 and when its rear end passes the roller 7, the roller 7 is pressed against the roller 1 by a spring 11. The contacting terminals of the sensors 15 and 17 leave a shaft 9 and the sensors 15 and 17 stop sending the signals, so that the rear end of the plate material 3 is detected. When the thickness and shape of the plate material 3 are not equal in the width direction, only one of the sensors 15 and 17 sends out the signal and the other sensor stops sending its signal. Therefore, when one of the sensors 15 and 17 transmits the signal, the entry of the front end of the plate material 3 is detected and when the both send out the signals, the separation of the rear end of the plate material 3 is detected to perform accurate terminal detection.
