耗も少なくなるなどの効果がある。[Effect] According to the present invention, the movement of the edge of the pipe conveyor is detected by the above-described structure and action, and each shape-retaining roller that keeps the shape by rolling the belt is acted to return the belt to the original position. As a result, since the belt is always held in the correct position, there is no possibility that the belt will be twisted and folded in half. In addition, by pushing the vicinity of the edge of the belt inside the overlapping portion of the belt with the belt pressing roller, the edge outside the overlapping portion of the belt is separated from the inside portion of the belt and the position detection roller is sure to contact the edge of the belt. Therefore, there is an effect that abrasion due to rubbing of the edge portion of the belt is reduced.
