<P>PROBLEM TO BE SOLVED: To enhance durability of a device itself by restraining a roller from deflecting, even when carrying a product of a heavy load, to surely make a double speed conveyor chain (19) carry and travel by using small driving and driven sprockets (11a, 11b, and 17a, 17b), and to reduce the size and weight in the device itself. <P>SOLUTION: Chain unit members (21) are endlessly connected in the required length by inserting a connecting pin (31) into a bearing hole (23b) and shaft support holes (23e and 29a) coincident in a state of arranging shaft support parts (23d) of the other chain unit member (21) so as to be positioned on the inside surface side of a bearing large diameter part (23a) of the adjacent one chain unit member (21) and arranging a double speed roller (29) between the pair of shaft support parts (23d). <P>COPYRIGHT: (C)2013,JPO&INPIT |
