Abstract
A Stacking Apparatus is proposed that performs the purpose of receiving the boxes being produced by a Rotary Die Cutter and transporting the boxes through the apparatus such that stacks of the boxes are created and exit from the discharge end of the apparatus. It embodies the four functional modules, Layboy Function, Shingling Function, Stacking Function and Hopper Function. These four functions are embodied such that it has the advantages of a fixed position Hopper Function and still provides Die Board Access, Running Layboy Roll Out and Sample Sheets.
Claims23
A sheet stacking apparatus, comprising:
- a first set of one or more conveyors including a layboy configured to receive boxes from a rotary die cutter;
- a hopper configured to support a stack of boxes;
- and
- a stacking conveyor configured to move boxes from the first set of one or more conveyors to the hopper, the stacking conveyor includes an input side and an output side, the input side is configured to be moved vertically between a low position where the stacking conveyor receives boxes from the first set of one or more conveyors and a high position that allows at least a portion of the first set of one or more conveyors to be positioned underneath the stacking conveyor, the first set of one or more conveyors is configured to be movable without moving the hopper such that at least a portion of the first set of one or more conveyors can be moved underneath the stacking conveyor when the stacking conveyor is in the high position to allow access to the rotary die cutter.
A sheet stacking apparatus, comprising:
- a first set of one or more conveyors configured to receive boxes from a rotary die cutter;
- a hopper configured to support a stack of boxes;
- a stacking conveyor configured to move boxes from the first set of one or more conveyors to the hopper, the stacking conveyor includes an input side and an output side, the input side is configured to be moved vertically from a low position where the stacking conveyor receives boxes from the first set of one or more conveyors and a high position;
- and
- a sample sheet conveyor with an input end configured to receive boxes from the first set of one or more conveyors when the stacking conveyor is in the high position, the input end is blocked from receiving boxes from the first set of one or more conveyors when the stacking conveyor is in the low position.
A sheet stacking apparatus, comprising:
- a first set of one or more conveyors configured to receive boxes from a rotary die cutter, a gap exists between the first set of one or more conveyors and the rotary die cutter, the first set of one or more conveyors includes wheels for moving the first set of one or more conveyors in a first direction;
- a hopper configured to support a stack of boxes;
- and
- a telescoping stacking conveyor configured to move boxes from the first set of one or more conveyors to the hopper, the telescoping stacking conveyor includes an input side and an output side, shortening the telescoping stacking conveyor allows the input side to move in the first direction, the first set of one or more conveyors are configured to be moved in the first direction away from the rotary die cutter without moving the hopper when the stacking conveyor is shortened and the input side moves in the first direction.
A method of operating a sheet stacking apparatus, comprising:
- transporting boxes from a rotary die cutter to a fixed location hopper via a first set of one or more conveyors and a stacking conveyor;
- and
- providing access to the rotary die cutter by raising the stacking conveyor and moving the first set of one or more conveyors such that at least a portion of the first set of one or more conveyors is beneath the raised stacking conveyor.
A sheet stacking apparatus, comprising:
- a first set of one or more conveyors including a layboy configured to receive boxes from a rotary die cutter;
- a hopper configured to support a stack of boxes;
- and
- a stacking conveyor configured to move boxes from the first set of one or more conveyors to the hopper, the stacking conveyor includes an input side and an output side, the input side and the output side are both configured to be moved vertically, the first set of one or more conveyors configured to be movable with respect to the hopper to allow access to the rotary die cutter such that at least a portion of the first set of one or more conveyors can be moved underneath the stacking conveyor when at least one of the input end and the output end are raised vertically.
