Object orientation adjusting device

An object orientation adjusting device for a roller conveyor configured to convey an object, the object orientation adjusting device comprising:

• a first roller chain part comprising:
• a plurality of sprockets configured to rotate in a direction perpendicular to a conveying direction;
• and
• a roller chain;
• a second roller chain part comprising:
• a plurality of sprockets configured to rotate in the direction perpendicular to the conveying direction;
• and
• a roller chain;
• a lifting apparatus configured to simultaneously lift the first roller chain part and the second roller chain part;
• a sensor configured to detect an orientation of the object on a plane;
• and
• a plurality of conveyor rollers configured to convey the object in the conveying direction,
• wherein
• the first roller chain part and the second roller chain part align in the conveying direction and are disposed between the plurality of conveying rollers,
• when a center of gravity of the object being conveyed in the conveying direction by the plurality of conveyor rollers is positioned between the first roller chain part and the second roller chain part in the conveying direction, the lifting apparatus is configured to lift the first roller chain part and the second roller chain part to a position higher than a height of the plurality of conveying rollers,
• the first roller chain part and the second roller chain part are configured to rotate in directions opposite to each other or rotate in a same direction at different speeds after being lifted to the position higher than the height of the plurality of conveying rollers,
• the object orientation adjusting device further comprises a stopper oriented in the direction perpendicular to the conveying direction and disposed on one side of a conveying path,
• the first roller chain part and the second roller chain part are configured to rotate in a same direction as each other to move the object to just upstream of the stopper after the orientation of the object is adjusted, and
• the stopper is configured to be pushed toward the object and to be pressed against the object after the object moves to just upstream of the stopper.
