A de-traying method and apparatus for removing articles from trays, is useful with a plurality of 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. The bottom is liftable from said base. A tray that is supporting an article on said bottom is transported to a detraying assembly. The article is detrayed at the detraying assembly by elevating the bottom at least to the level of the tray rim with an article lifter from below the tray. The article lifter includes a lifting base and a plurality of lifting blocks fixed to the lifting base. The lifting blocks are sized and arranged to engage the tray bottom through the opening in response to the lifting base being elevated. The lifting blocks are sized and arranged 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.

A caster wheel alignment system for selectively re-orienting improperly oriented caster wheels for transport vehicles of a conveyor system, such as a circular sorter. The alignment system includes a main support frame couplable with the conveyor at a drive track of the conveyor. The system includes a horizontal cam for adjusting an orientation of the caster wheel from a leading orientation to a trailing orientation. In some forms, the alignment system may include a bypass system, such as a float frame, supporting the horizontal cam, and a vertical cam. The vertical cam provided to temporarily move the float frame and horizontal cam away from the transport vehicle and/or drive track to permit the vehicle to move through the alignment system. The vertical and horizontal cams coordinate to intercept and correct improperly oriented wheels without significantly impeding the movement of the transport vehicle along the drive track.

A conveyor system for grouping containers including a conveyor module configured to convey and meter a stream of containers of various dimensions a first star wheel and a second star wheel configured to move a plurality of first containers along a first travel path, wherein the first containers each have a first geometric center, and wherein the first travel path is defined by the geometric center of the first containers, and a third star wheel and a fourth star wheel configured to move a plurality of second containers along a second travel path, wherein the second containers each have a second geometric center, and wherein the second travel path is defined by the geometric center of the second containers, wherein the first travel path and the second travel path are substantially similar.
