<P>PROBLEM TO BE SOLVED: To provide a temporal stopper of a conveying line, which does not emit noises, is hardly damaged and does not cause a flaw to be generated in a material to be conveyed. <P>SOLUTION: The stopper of a conveying line catches a circular steel tube 10 to temporarily stop it at a descent terminal end of a descending slope 1 conveying the circular steel tube in a diametrical direction of the circle of the circular steel tube 10. The stopper of the conveying line includes: a receiving member 2 for receiving the material to be conveyed that arrives at the descent terminal end of the descending slope, on a recessed curved surface 3 that has a recessed curve in a conveying direction; and a backward-feed stopper 4 that is provided in an end of the receiving member on an entering side of the material to be conveyed and configured to be movable upward and downward so as to allow the catching of the material to be conveyed in the moved downward 8 state thereof and prevent the backward-feed of the material to be conveyed that is received on the recessed curved surface 3 in the moved upward 7 state of the backward-feed stopper. <P>COPYRIGHT: (C)2012,JPO&INPIT |
