Twisting detecting and correction devices in a tubular belt conveyor.

摘要

A tubular belt conveyor transports bulk material without spillage. The longitudinal side edge of the belt (1a) is held between a pair of pinch rollers (9), and a guide roller (10) is disposed perpendicular to the length of the pinch roller (9). When the tubular belt (1a) is twisted, the edge moves toward the guide roller (10) and presses it up. The movement of the guide roller (10) is transferred via a limit switch electrically (14) to a correction roller (15) under the belt (1a) to correct the twisting. The guide roller (10) itself forces the side edge in the opposite direction to correct the twisting, too.
