Roller for curved conveyor, curved conveyor, and curved belt

Abstract

Provided are a curved conveyor, a curved belt, and a roller for a curved conveyor which is capable of suppressing uneven wear of a sleeve or a curved belt. An endless curved belt is mounted on a plurality of rotatable rollers that are radially arranged, and the curved belt is driven by the rotation of a roller 12a, which is a head roller, and a tail roller. A sleeve 18 is fitted to each of the roller 12a and the tail roller, and brought into contact with the rear surface of the curved belt on the outer peripheral side. By making the height ta of the end part of the sleeve 18 on the inner peripheral side larger than the height tb of the end part on the outer peripheral side, a force is made to act on the entire sleeve 18 in a distributed manner.
