PROBLEM TO BE SOLVED: To solve the problems of carrying a cargo on a conveyor belt even if a round portion has a small diameter, by one belt without changing to another one and enabling cargo not to escape from the belt, not to have the belt sliding up on the outside of this curve, and not have the belt folding in two on the inside of this curve.SOLUTION: A vertical roller is arranged on the inside and the outside of a round portion of the belt, to restrain a slide in the lateral direction of the belt. A semispherical push roller is also pushed against loose places, and its inner peripheral side distance and an outer peripheral side distance are adjusted in a state of keeping a balance of tension between the inside and the outside of the belt. |
