To provide a product direction changing device which rapidly and consistently changes the conveying direction of products conveyed in one row in the longitudinal direction at a predetermined angle, for example, to provide a product direction changing device which changes the flow of the products in the longitudinal direction to the flow in the transverse direction if the angle of change is 90°.

Products A, B, C conveyed in one row in the longitudinal flow from the previous process are corrected in a predetermined pitch by a spacing correction conveyor including an intermittent operation type belt conveyor 2b. A moving and changing mechanism 24 is operated by the drive of a driving mechanism 22, and suction cups 45, 45 of suction members 42, 42 suck the products A, B above the conveyor while moving a suction unit 23 at the same speed as that of the carrying conveyor. The suction member 42 is turned by the cam operation between a plate cam 55 and a cam follower 59, and when the direction is changed by, for example, 90°, the suction is released to deliver the products to the conveyor. The spacing of the products is corrected, and the direction is changed after the suction, changing the direction stably.
