Abstract

PURPOSE:To simplify the structure of the above device for synthetic-resin-made food cups or the like by transferring and aligning articles while supporting the flanges of the transferring articles by a pair of endless belts having a prescribed distance which are traveled in a slower speed than the conveyor provided on a conveyor, so that the articles are returned onto the conveyor on the downstream side. CONSTITUTION:A number of flange-fitted article transferred on a conveyor 3 in an unrestricted condition are turned toward the center of the conveyor 3 by receiving the restriction of guide plates 15a, 15b of a position restricting member 5. Then, the articles are transferred to a pair of endless belts 8a, 8b. And the flanges of the articles are put on the endless belts 8a, 8b so as to be held, so that the articles are transferred at a slower speed than the conveyor 3. Since the transfer speed is slower, subsequent articles are successively brought into a connected state and are aligned. Then, the articles are again discharged from the outlet 4 of an endless belt device 4 onto the conveyor 3. By this constitution, the structure can be simplified.
