Claims

[Scope of Claim for Utility Model Registration] 1. A self-aligning device for a belt conveyor, in which a number of protrusions protrude from the surfaces of a pair of left and right rollers. 2. A central carrier roller rotatably provided on the conveyor machine frame, and on the left and right sides of this central carrier roller, the outer side of the axis is raised and the outer side of the axis is located on the front side in the conveyor traveling direction, A self-aligning device for a belt conveyor, which has a pair of left and right carrier rollers rotatably provided on a conveyor frame, and a number of protrusions protrude from the surfaces of these left and right carrier rollers. 3. A belt conveyor in which the self-aligning device according to claim 2 is installed such that its carrier roller is located at a higher position than other carrier rollers. 4. A rotating frame provided horizontally on the conveyor machine frame and facing downward, and a pair of left and right return rollers rotatably provided on this rotating frame with the outside of the axis being lower. A self-aligning device for a belt conveyor, which has a large number of protrusions protruding from the surfaces of these left and right return rollers, so that a conveyor belt comes into contact with the left and right return rollers from below. 5. A belt conveyor in which the self-aligning device according to claim 4 is installed such that its left and right return rollers are located at a lower position than other return rollers supporting the conveyor belt on the upper side.
