  • Side push divider
    Patent number: 4069908
    Abstract: Objects moving single file on an infeed conveyor are diverted onto an intermediate conveyor where they are separated, and then sequentially pushed onto a wider take away conveyor having lane defining means for receiving the objects in discrete lanes. A side push conveyor has an upper run which moves at a speed related closely to that of the intermediate conveyor, and has cam operated slats or pushers which cooperate to define pockets for urging the objects off the intermediate conveyor onto the take away conveyor and into the appropriate lanes.
