Systems and methods for feeding articles to and removing articles from an automatic washer

Systems, methods, and devices for feeding articles to and removing articles from an automatic washer, for example, a tunnel-type automatic washer are provided. The systems and methods employ conveyors, for example, belt conveyors, gantry-type conveyors, and shuttle-type conveyors, for handling and conveying articles to or from a washer or an intermediate station. The conveyors utilize arm-end tooling adapted to grasp and manipulate at least one article, but may typically handle a plurality of articles. The arm-end tooling includes cylinder-based actuators that can be operated and controlled by an automated control system. The handling of the articles can be assisted by using a vision-based system. Aspects of the invention are suited for use in handling laboratory equipment, for example, utensils and containers, such as, laboratory animal cages, in particular, cage tops and cage bottoms.
