ABSTRACT:
The device shown is a dual purpose unloader for the sheet holder bins of a paper distribution system, such as a collator. The bins of a collator are sometimes sloped to allow gravitational settling of the sheets as they are fed into the pockets. The illustrated unloader is an elongated open channel with an internal slidable rod. One set of grippers is mounted on the open channel and another set of grippers on the rod. A spring urges the two sets to move into a gripper closed position, and manual handles provide a means for opening the set of grippers. A mounting frame is available for guiding the unloader into proper registration with the collator pockets if manual placement is not convenient or desired.
