  • Patent number: 9004084
    Abstract: An apparatus and method for removing waste from a soiled container that houses laboratory animals and has an opening is disclosed. The apparatus includes a conveyor having a receiving end for receiving containers from a stack of containers. The stack is disposed such that the openings are upwardly oriented. The apparatus also includes a manipulator that aligns with and engages an uppermost container of the stack and causes the uppermost container to be separated from the stack and to be flipped over onto the receiving end of the conveyor such that the opening is downwardly disposed. Waste discarded from the container falls through openings in the conveyor, and a waste receptacle disposed below the conveyor collects the discarded waste. The conveyor advances to transport the container away from the receiving end toward a discharge end of the conveyor.
