Abstract
A de-traying method and apparatus for removing articles from trays, each of the trays having a base, a rim around the base and an opening in said base and a bottom covering said opening and liftable from said base. A tray supporting an article is transported to a detraying assembly where the article is detrayed by elevating the bottom at least to the level of the tray rim with an article lifter having a lifting base and a plurality of lifting blocks. The lifting blocks are sized and arranged to engage the tray bottom through the opening in response to the lifting base being elevated, and to maintain orientation of the tray with at least one of said blocks positioned outside of the tray adjacent the rim. The article is displaced off of the elevated tray bottom.
