  • Patent number: 4192359
    Abstract: Container filling apparatus and method are disclosed in a form for loading green beans into containers, such as hampers, boxes, crates and the like. A conveyor deposits the beans onto a turntable having a continuous series of ports along its peripheral portion for passage of the beans into the containers below the ports. Beans which do not drop through the ports remain on the turntable and are carried to a first rotary unit which propels the beans in a direction opposite the rotational direction of the turntable and at least partially into the ports to substantially fill the containers. The rotary units are above the path of the ports and remove excess beans from atop the ports. A compactor for the beans in the containers is provided along the path of the ports immediately downstream of the rotary unit, to eliminate voids between the beans and the beans on the turntable are carried to a second rotary unit which again propels the beans away from itself for ultimate removal through the ports.
