Abstract:
A belted conveyor roller nip point automatic protection device comprising of a primary pull chord length, sleeved with a shorter semi-rigid pliable support rod; the primary pull chord spanning across the width of said conveyor, on the upstream side near any one of a conveyor belt's roller nip point; each end of the said primary pull chord is reeved through guides rigidly attached onto each side of said conveyor, until the ends of the support rod are resting onto their respective guides; one end of the primary pull chord is rigidly attached to one side of the conveyor; the other end of the primary pull chord is linked to a secondary pull chord longitudinal to, and on the opposite side of, the conveyor, this secondary pull chord in turn being connected to a conveyor-disabling safety device, for which, if the primary pull chord is inadvertently entrained into the nip point, it in turn draws on the secondary pull chord which then trips the safety device and automatically de-energizes the conveyor drive motor, stopping the belt.
