Abstract

See full text

The present invention relates to a conveyor belt alignment system by which a pair of alignment rollers are mounted on a carrier frame about a pivot axis that is situated at the approximate transverse center between opposed longitudinal side edges of a conveyor belt. The alignment rollers are spaced longitudinally to accept and form a portion of the conveyor belt into a substantial 's' configuration. The centrally pivoted carrier frame and alignment rollers are pivoted by a pair of bladders 50, 51. Inflation of the bladders is controlled through a sensor 54 provided to detect the transverse position of an adjacent belt edge. If the belt edge shifts in one direction, the sensor detects such motion and operates the drive to selectively inflate one or the other of the air bladders to correspondingly shift the belt aligning rollers. The misaligned belt is brought back to the desired tracking configuration where the sensor detects the desired orientation and permits the system to return to a normal, desired operating mode.
