ABSTRACT:
Disclosed is a chain-type conveyor having a direction-changing roller capable of easily changing the orientation of an article to continuously transfer the article, without using any separate direction-changing unit at a corner part of the conveyor, in the case in which the transfer direction of the article has to be changed during the transfer of the article by a conveyor, thereby reducing a cost of the article and usefully utilizing a limited space. The chain-type conveyor for transferring an article in a straight direction when the chain-type conveyor is driven by driving means includes a plurality of chain plates foldably connected to each other, a pair of brackets each having a lower portion symmetrically fixed to an outer surface of the chain plate in a front/rear direction and an inclined upper portion, and direction-changing rollers rotatably coupled to the brackets in a diagonal direction and changing a transfer direction of the article, which is transferred along a roller-type conveyor and then stopped by a stopper roller rotatably installed to a front portion of the chain-type conveyor, by a rotational force generated by friction between the article and the direction-changing roller.
