Self-retracting pallet retention device

Abstract

A product unloader for product sortation systems includes a self-retracting pallet retention device for capturing and retaining upended pallets. The product unloader has at least one self-retracting pallet catch. The pallet catch includes a connector for maintaining the catch in an operative position, a guide configured for directing movement of the connector between raised and lowered positions, and a limiter defining the guide positions. The connector, guide, and limiter combine to allow the catch to move by force of gravity about an axis of rotation of the connector. The catch further includes a catch edge that is in contact with the pallet.
