ABSTRACT:
In a continuous cycle the apparatus denests stacked plant pots and plant flats and fills the flats with the pots. Two piston mounted vacuum grippers employing arrays of suction cups are mounted to a frame. The flat gripper moves vertically to destack an array of plant flats or trays, and the pot gripper moves vertically to destack an array of plant pots. Both grippers are moveable between a retracted position, an unloading position, and a multiplicity of loading positions. A carriage is reciprocated on wheels between a first position beneath the flat gripper in its unloading position and a second position beneath the pot gripper in its unloading position.
Stacks of nested plant flats and arrays of stacks of nested pot--both of which may be contained in their original shipping containers--are positioned beneath their respective grippers and aligned with the flat and pot grippers by means of adjustable alignment flanges.
The pot gripper deposits an array of pots into a flat conveyed by the carriage which is then removed from the carriage by an ejecting mechanism. Pneumatic vibrators vibrate the grippers to prevent lifting of multiple units.
