ABSTRACT:
A denesting apparatus for removing a single packing tray from a stack of trays. The tray has a plurality of cups for containing the fruit. The tray has a plurality of pick receiving areas for receiving picks on the denesting apparatus which engage the tray and remove the tray from the stack. The pick receiving areas are located in a sidewall of the tray, such that the locations of the pick receiving areas are independent of the locations of the cups. The pick receiving areas are shaped to permit substantially unimpeded movement of the picks into the pick receiving areas and clamping of the tray between the picks and adjacent alignment members. The alignment members are located to support the stack of trays while the picks engage a single fruit packing tray.
