ABSTRACT:
An automatic stacker is disclosed having finned rotors to be turned incrementally so respective fins are horizontal and are spaced to support thereon the edges of a flat partition. Such partitions are successively moved onto the horizontal fins and the rotors are successively incrementally turned so as to drop the partition held thereon and to receive the next succeeding partition. The partitions thus dropped fall onto a conveyor on which succeeding partitions are overlapped, and such partitions are moved in groups to an inclined plate at which the partitions are forced to incline upwardly and close together to form an inclined stack. Different arrangements are disclosed for orienting the inclined stack to the vertical and thence moving the vertical stack to a tie station, including a movable inclined plate and cylinders with pistons for successivly moving the inclined stack to the vertical and forcing it to the tie station, and including a fixed inclined plate and pushers operated by a linear actuator or chains to move the inclined stack along a plate that makes a transition from the incline to the vertical.
