Abstract

PURPOSE: To ease the detection of a damage or other defects in a conveyor belt, by establishing a constitution in which a pin descends, owing to weight, to a frame, fixed along a belt, in order to operate a microswitch.
CONSTITUTION: With a belt 1 at a prescribed speed, a weight 23 takes and elevated position as shown in chain lines 23'. At this time, since the weight 23 is apart from a pin head 15, the weight 23 does not affect a pin 14. The pin 14 also takes an elevated position 14' because the pin 14 is pushed up by a springly lever 18 of a microswitch 17, so that the microswitch closes the electric circuit to continue the belt 1 running. If the belt 1 should be damaged and come off a pulley 19 because of an accident, the pulley 19 stops because it is no longer driven, and the turning torque due to entrifugal force, which have been affecting the weight 23, disappears. Thus, the weight 23 drops an account of gravity to press down the pin 14 and the lever 18 as well, which makes the microswitch 17 break the electric circuit.
