ABSTRACT:
A magnetic roller conveyor wherein a plurality of magnetic rollers are arranged in a row, each of which includes an outer drum and an inner drum disposed in the outer drum and having magnets mounted thereon. The outer drum is rotated while the inner drum is fixed, whereby objects are conveyed by making use of magnetic forces of the magnets. Each roller includes a dampingly magnetized segment mounted past the vertex of the roller, the force of the segment decreasing in the direction of travel to facilitate transfer to the adjacent roller.
