Apparatus for transporting lithographic plates

Apparatus for transporting lithographic plates from a first location at which the plates are delivered on edge by an overhead conveyor to a second location vertically below the first location, comprising:

• input means at the first location for loading individual said lithographic plates, said input having a chute means defining a curved path for receiving the lithographic plates as oriented on edge and re-orienting the lithographic plates along the curved path for substantially horizontal placement;
• and,
• storage means for receiving the lithographic plates at the first location and delivering the lithographic plates in succession to the second location, the storage means having a rotary shelf conveyor in which a series of plate trays mounted on an endless loop and operable to bear the lithographic plates on their sides are moved around an endless path including a portion extending vertically between said first and second locations, and the plate trays being upwardly inclined from the endless loop during movement thereof along said portion of the path extending vertically between the first and second locations, the input means delivering the lithographic plates onto the plate trays at a substantially horizontal orientation, and the input means having a transfer conveyor for transferring the lithographic plates received from the chute means onto an adjacent tray of the rotary shelf conveyor.
