DEVICE FOR CONVEYOR BELT CENTERING Russian patent published in 2008 - IPC B65G39/71 B65G15/64 B65G21/12 

FIELD: transportation.

SUBSTANCE: device contains through roller with possibility of conveyor belt resting on it and consisting of rollers located on bracket mounted capable to yaw relative to pin joint fixed using cross-beam on belt runs, track wheels capable to roll over fixed on runs guides. Pin joint is equipped with additional horizontal hinge providing possibility for carrying roller to rotate in vertical plane. Track wheels are made with round face shape of their rims and are mounted on additional brackets fixed on free ends of carrying roller bracket on its bottom. Both guides are made flat, tilted to runs plane with raise in direction of conveyor belt travel and are equipped with retainers capable to interact with track wheels when carrying roller is rotated in horizontal plane by limit angle. Clearance between inner edges of guides is selected from relation b≤(B²-h²)^0.5cosα, where b - clearance between inner edges of guides, m, B - distance between track wheels, m, h - rise height of guides, m, α - limit angle of carrying roller rotation, degrees.

EFFECT: increase of centering effect for conveyor belt.
