ABSTRACT:
A three dimensional sorting apparatus utilizes a plurality of frame members, supported for circulating movement in a closed path. A tray is mounted for up and down movement on each of the frame members and is guided along rails which determine its height. Change-over rails, controlled to move up and down, are provided to connect a first guide rail extending past an intake station to a selected one of a plurality of secondary guide rails extending at different levels past a plurality of discharge stations. This enables an article to be discharged into a selected one of several discharge ports at a selected discharge station. Discharge is carried out by pivoting the tray forward upon release of a tray-retaining latch by a discharge assisting device at each discharge station. Alternatively, the article is carried on a conveyor driven by a pinion which is activated by a discharge assisting rack at each discharge station.
