A stacker assembly for a conveyor system. The conveyor system includes a belt conveyor to convey a plurality of articles having a size such that the sides of the articles overhang the side edges of the conveyor. A pair of lift blocks are disposed beneath and on opposite sides of the conveyor and can be moved from an outer retracted position to an inner lifting position. In the lifting position the inner edges of the lift blocks are located beneath the overhanging sides of an article stopped on the conveyor. The lift blocks are elevated by means of a fluid cylinder to raise the article above the conveyor and into a storage rack. As the article is elevated, cams on the lift blocks engage cam surfaces on spaced support members to wedge the support members apart and enable the articles to be elevated above the support members. The support members automatically return to the supporting position to hold the article in the storage rack. The lift blocks are then moved laterally outwardly and then downwardly to their original position beneath the level of the conveyor.
