Overload detector and interrupt for conveyor chain |
摘要 |
A conveyor system that may be driven in a forward or a reverse direction is provided with jam detectors that are effective to interrupt the operation of the conveyor chain (10) upon encountering a jam condition in either direction of drive. The chain (10) is driven about idler sprockets (19 and 53) mounted in housings (21 and 51) that are slidably mounted on a T-bar frame (22). When the chain is driven in a forward direction A, a jam condition causes housings (21) to slide and operate a switch (23) to interrupt power to a motor (18). When the direction of drive is reversed, housing (21) is held from movement by a lock (47), and a lock (54) associated with housing (51) is released to allow the housing (51) to shift in response to a jam condition to operate a switch (58) to again interrupt the power applied to the motor (18).
