Title: Conveying article stopper for roller conveyor
Inventor: YAMAZAKI FUMIO
IPC: B65G47/88
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To enable conveying speed high even in a conveying article having a low strength by providing a flat plate member that has been provided so as to be retractable through the gap between the rollers that have been arranged in parallel, so that the surface pressure at the time of collision of the conveying article can be reduced. SOLUTION: Suppose that a conveying article 6 is conveyed from right to left, first, the piston rod 32 and the fixed plate 33 of an elevator 3 are moved upwards, and accordingly the flat plate member 2 is also raised, so that at least a part thereof is projected upwards through between the rollers 51. When the conveying article 6 is still conveyed, it is soon abutted on the abutting surface 22 of the flat plate member 2. In that case, the flat plate member 2 is slightly turned making a base end part 21 a center, and pushes in the operating rod 42 of a shock absorber 4. As a result, the shock absorber 4 absorbs the kinetic energy of the conveying article 6. Thus, even if the strength of the conveying article 6 itself is low, the damage given to the conveying article 6 can be reduced as compared with the conventional one.
