ABSTRACT:
A trash bag opener and removal apparatus has a feed conveyor, a housing assembly and a discharge conveyor for opening and removing plastic and paper bags filled with material and discharging the material at a chute end of the discharge conveyor. The bags are routed by the feed conveyor into the housing assembly, which has a separate input conveyor, a slicer assembly, a slitter assembly, a bag stripper assembly and first and second paddle wheels. The input conveyor is located proximate to the feed conveyor and travels faster than the feed conveyor to upset the bags and ensure that the bag bottoms are exposed for the slicer assembly. The slicer assembly has a rotating, cylindrical drum with three serrated blades along its length and oscillates to tear the bags open. The paddle wheels retard and assist in moving the bags and refuse from the slicer assembly to the slitter assembly, which has rotating notched disk blades to rip the bags open, and then to the discharge conveyor. The bags and refuse then pass beneath the bag stripper assembly, which has rotating, extending fingers that grab and remove the torn bags from the refuse. The fingers retract as the bag stripping assembly rotates and then drop the bags on top of the refuse. The discharge conveyor then moves the bags and refuse to the chute end for discharging the refuse.
