ABSTRACT:
A high speed apparatus for selectively discharging articles from a conveyor system, including a conveyor to convey the articles in a path of travel. A rotatable discharge member is mounted for rotation above the conveyor and includes a plurality of parallel grooves that extend longitudinally of the path of travel. Each article, as it moves along the conveyor, enters and is stopped within one of the grooves, and the discharge member is then rotated by a pair of cooperating drive units to discharge the article laterally from the conveyor. A first of the drive units includes a fluid cylinder that operates to rotate the discharge member through an arc that is less than the arc between adjacent grooves, and the second drive unit includes a cam mechanism which completes the indexing of the discharge member while the first drive unit is returned to its original position. A locking mechanism can be incorporated with the second drive unit to lock the discharge member in the indexed position.
