Abstract
A retainer arm assembly ( ) for use in a container unloading assembly ( ) for unloading containers (C) of various sizes. Pivot posts ( ) are attached to opposite sides ( ) of a fixture ( ) into which containers to be unloaded are set. The fixture is movable to invert the container and dump its contents. Retaining arms ( ) are mounted on each pivot post and moved by the pivot posts to a position above an open end of the container. The retaining arms now retain container in the fixture as the contents of the container are dumped. A mechanism ( ) is activated to rotate each post from a first position to a second position, after the container is placed in the fixture, for the retaining arms to be located above the container. Other of the retaining arms mounted on each pivot post may contact the container as the pivot posts are rotated.
