Abstract

PURPOSE:To prevent breakage of a sanding belt and occurrence of fire accident by energizing a follower member installed coaxially with a roller, on which the sanding belt is loaded, in the opposite direction to the belt, by sensing the belt end using this follower member, and thereby enhancing the operational stability. CONSTITUTION:When a sanding belt 16 is misplaced during running on its track aside onto either side to have caused dislocation of the belt end from the edge of a guide roller 12, the belt end attains the receipt face a of a follower member 20, and the wear force produced thereby will rotate the follower member 20 in the same rotational direction. When this follower member 20 has rotated for a specific angle, an actuator piece 25 confronts a close switch 26, which will emit a signal to put a steering roller 15 in eccentricity in the opposite direction. This sensing signal is transmitted to a solenoid valve via a control circuit, and the valve changes over the operating direction of a pneumatic cylinder to modify the bely running into the right track by pushing it in the opposite direction, i.e. in the direction moving apart from the follower member 20. Thus sensing of belt end is made with a follower member to provide a high operational stability, which should contribute to suppression of risk for accident occurrence.

That is, the sanding belt 16 is shifted toward one of the force sides due to track running, and the end of the sanding belt 16 is moved toward the guide roller 12.
When it comes off from the end, this ear end reaches the receiving surface a of the passive body 20, and its abrasion force causes the passive body 20 to rotate in the same rotational direction. Then, when the passive body 20 rotates by a predetermined amount of +4, the actuating piece 25 directly faces the proximity switch 26, and the proximity switch 26 sends a signal that biases the take-up roller 5 by 7fT in the opposite direction. This makes it possible to detect the ear tip with good sensitivity and sensitivity from the ear tip contact with the passive object 20 to the signal transmission of the proximal touch 26. Also, when the ear tip is separated from the receiving surface a, the coiled spring 24 The passive body 20 is returned to its original position by the action, and the return operation is also performed reliably and quickly.

In addition, in the present invention, since the receiving surface a faces the extended circumferential surface of the roller on which the sanding belt 16 is suspended, the edge end is smoothly transferred to the receiving surface, thereby preventing damage to the belt. Accidents can be significantly reduced. Furthermore, by forming the receiving surface from a ceramic material, the generation of frictional heat or wear can be minimized, allowing for durable and stable detection operations.
