Aspects of a turn conveyor system are described. In one embodiment, the turn conveyor system includes a first conveyor, a second conveyor adjacent to the first conveyor, a lateral conveyor extending between the first conveyor and the second conveyor, and a turn arm. The turn arm may extend across the second conveyor and be coupled to the second conveyor at a position corresponding to an end of the lateral conveyor. In one embodiment, the turn arm includes an extension bar, a rolling bumper having an angular degree of freedom, and an extension down shaft. According to various aspects, the turn conveyor system may displace an article in a first direction with the first conveyor, laterally displace the article in a second direction onto the lateral conveyor, laterally convey the article toward the turn arm, and rotate the article from a first orientation to a second orientation using the turn arm.
