  • Patent number: 5441381
    Abstract: This is a box stacker which is related with a box shaping machine. The boxes come out at the bottom of the machine and drop by gravity onto a conveyor belt and are conveyed to one end of this belt where the stacker which is object of this invention is located. It has upright adjustable guides, two in front and two at the rear which correspond to the vertical corners of the box, and are at the same time coupled in pairs to two cross shanks respectively, which are in turn coupled at the end to the cross shafts which are joined by longitudinal screws. The screws turn in either direction and the upright guides will be adjusted to fit to the dimensions of the boxes. When one of these lies between the four upright guides, a pusher goes up and moves the box to allow room for another one and so on successively. When a stacked row has been formed, which is automatically counted, it will be moved by a pusher towards a platform which is formed by two plates at right angle.

  • Patent number: 5435541
    Abstract: A frame is designed for temporarily supporting a horizontal plate-like workpiece until it undergoes a vertical translation between guiding and squaring stops, which frame is located in a machine. The frame comprises lateral retractable supporting surfaces which are either edges of a horizontal flat bar or sides of a horizontal flat bar. When the supporting surfaces are the edges of the horizontal flat bar, the bar is mounted so that it can be moved from a straight line position retracted from the supporting of the sheet to a curved position for supporting the edge of the sheet. The bars can also be positioned utilizing the side and are moved either by pivoting or by a four-bar linking arrangement between the retracted and engaged positions. Finally, the bars can be mounted for rotation along one edge between the engaging and retracted positions.

  • Patent number: 5282716
    Abstract: A stack of signatures are dropped upon the platform halves of a rotatable platform, the platform halves being raised to reduce the free fall distance from the point where the stack of signatures are dropped and a lower stack ejection position. The platform halves are lowered as each stack of signatures is delivered thereto. Eventually, the platform is lowered to the stack ejection position and the pusher is pushed through a gap provided between the platform halves to eject a completed bundle from the platform. The pusher moves through the gap as the platform is being raised or lowered to significantly reduce the cycle time. Stack compressors are selectively movable to a position above the turntable and by selectively raising the platform halves, the accumulated stack of signatures on the platform halves are squeezed between the compression members and the platform halves to form a neat, compressed bundle. The turntable is rotatable through a half-revolution to form compensated stacks.
