Abstract: The present invention provides an article alignment device that can inhibit posture disorderliness when articles land on a conveyor belt. The posture of bags when the bags transfer from an input conveyor to a first aligning conveyor is inclined in such a way that the portions of the bags that land on bags already placed on the first aligning conveyor are higher and the portions of the bags that land directly on the first aligning conveyor are lower, so the bags land on the first aligning conveyor before or at the same time that they contact the bags that were placed on the first aligning conveyor before them. Additionally, the frictional force between the first aligning conveyor and the bags is greater than the frictional force between the bags, so sliding between the bags is prevented, as is posture disorderliness.
