Abstract:
A reversible belt steering assembly (1) for centering of conveyor belts which during operation is subjected to a lateral displacement away from a neutral position, comprising:a rotating mechanism (3, 19) which supports at least one steering roller for the conveyor belt, and which is rotatably attached to a first fixed beam (2) for rotation about an axis (a) perpendicular to the conveyor belt,a first set of guide rollers (9) for abutting the sides of the conveyor belt, and which is thus displaced laterally depending on the lateral displacement of the conveyor belt, anda first transfer mechanism supporting the first set of guide rollers (9) for transferring the lateral displacement of the first set of guide rollers (9) to the rotating mechanism (3, 19), to rotate the steering roller to a position where it guides the conveyor belt back to the neutral position, characterized inthat the reversible belt steering assembly (1) comprises a second set of guide rollers (9') corresponding to the first set of guide roller, and a second transfer mechanism corresponding to the first transfer mechanism,that the two sets of guide rollers (9,9') and the two transfer mechanisms are arranged mutually opposite and inverted with respect to an intermediate axis of symmetry which is transverse to the longitudinal direction of the belt and extends through the axis (a) of the rotating mechanism, andthat the reversible belt steering unit (1) also comprises a switch mechanism for disconnecting and connecting the first and second transfer mechanisms in relation to the rotating mechanism (3, 19).
