Abstract
An automatic system for depalletizing or destacking items, containers or crates. The automatic depalletizing system includes an electronically controlled, automated, lift conveyor having a specialized pick mechanism at its free end, and having a self-contained hydraulic power supply system. The conveyor sequentially lifts pre-stacked crates, containers or items and places them in a single-file on a rotating conveyor automatically (hands free operation or individually controlled). Crates, containers, or items are automatically destacked or depalletized by placing the free end of the depalletizing conveyor in its uppermost position, pushing a dolly having a number of crates stacked thereon adjacent the free end of the depalletizing conveyor, pressing the cycle start button to activate the depalletizing conveyor and pick mechanism, the pick mechanism retrieves the uppermost crate and pulls it onto the upper end of the depalletizing conveyor and thereafter indexes downwardly to a position adjacent the second item from the top of the stack. This sequential removal of the crates from the stack continues until the lowermost crate is removed. When the last crate has been transferred to the conveyor, a lower limit switch is energized which causes an up solenoid valve to move the free end of the conveyor upwardly until the uppermost ready position has been reached and immediately stops belt rotation.
