PURPOSE:To prevent the one-sided traveling and meandering of a conveyor belt which carries-out assortment of the transported articles having the length larger than the width of the belt in the direction perpendicular to the direction of advance by extending a bead in the longitudinal direction on the back surface of the belt and installing the ball bearings for supporting the bead shoulder part. CONSTITUTION:A belt conveyor 4 is traveled in a prescribed direction by the drive of a driving pulley 31, and since a bead 2 for preventing the one-sided travel or meandering of a belt 1 is installed onto the back surface of a belt body 10, all the range of the belt surface forms the effective transport range. Therefore, even if a transported article has a dimension larger than the width of the belt, transportation is not obstructed. Further, the bead 2 on the back surface 11 of the belt is supported from the both sides by ball bearings 41 and 41, meandering of the belt 1 during traveling is suppressed. Therefore, even if a heavy transported article is delivered in the transverse direction of the belt 1, the one-sided traveling of the belt following the transported article is prevented, and stable traveling in a prescribed direction is permitted, since the belt 1 is supported and fixed in the prescribed direction by the bead 2. |
