CENTERING SERPENTINE SENSING DEVICE OF CONVEYOR BELT WITH LIGHT EMITTING UNIT

摘要

PURPOSE: A centering serpentine sensing device of a conveyor belt is provided to easily detect the rigidity reduction of the conveyor belt operated in a simple structure comprising sensors using a light emitting unit and a light receiving unit and to prevent a wrong operation by accurately sensing a serpentine state of the belt. CONSTITUTION: A centering serpentine sensing guide device of a conveyor belt(11) comprises sensing units formed at both sides of a centering roll for holding and supporting the conveyor belt to detect and correct the bias and serpentine of the belt and a centering regulating unit having a cylinder and the centering roll. A centering serpentine sensing device of the conveyor belt has a sensing unit(12) mounted at upper and lower sides of both edge surfaces(11a) of the conveyor belt to detect the serpentine and bias of the belt. The sensing unit comprises a light emitting porter sensor(12a) and a light receiving porter sensor(12b) that are separated from each other.
