Abstract

PURPOSE:To prevent the occurrence of noise by carrying a work by guide rollers which are moved by endless chains, and thereby concurrently moving moving bodies in the transverse direction so as to be shifted to each side of branch paths in a shifting device by which a carrying path is shifted from an inner carrying path to each branch carrying path. CONSTITUTION:A group of rollers 20 is circulated so as to be moved with chains 19 driven by a drive device 12, so that a particle 56 is thereby carried along a main carrying path 2. At this time, a guide rollers (not shown) is moved together with the group of rollers 20 in the transverse direction of the group of rollers 20 so as to be reciprocated while being guided by a group of guide bodies 30, and/or is moved straight along the main carrying path 21. For example, selection is determined by a direction device 52A whether each guide roller of moving bodies 25 guided by each start end guide section 31A is moved straight or is moved to the oblique direction while being guided by an inner moving 12A. If movement in the oblique direction is therefore selected, the carrying path can thereby be shifted to each branch path 53A or 53B.
