Title:
AUTOMATIC CORRECTION OF LATERAL CONVEYOR BELT DRIFT
Document Type and Number:
WIPO Patent Application WO/2005/108250
Kind Code:
A1
Abstract:
The invention provides a conveyor belt support frame assembly (12) which automatically mechanically corrects lateral conveyor belt drift. The assembly (12) includes a movable swivel frame (22) mounted on a base frame (18), and at least one, preferably three, support rollers (24, 26, 28) mounted on the movable frame (22). At least one sensing member (50, 150) is positioned for automatic displacement in response to lateral drift of the conveyor belt beyond a predetermined tolerance, the sensing member (50, 150) being connected to the movable frame by a mechanical linkage (54, 154) for effecting automatic displacement of the movable frame (22) in response to forced displacement of the sensing member (50, 150), to move the movable frame (22) into a position for correcting lateral drift of the conveyor belt by interaction of the conveyor belt and the support rollers (24, 26, 28).
