Abstract

The present invention provides a denesting apparatus ( 100, 200 ), the apparatus comprising: •—one or more closed loop conveying tracks ( 130, 230 ), each closed loop conveying track comprising a plurality of sets of one or more de-stacking means ( 140, 240 ) movingly configured thereon through one or more de-stacking means moving mechanism ( 150, 250 ): •—one or more stacking magazines ( 120, 220 ), each adapted to hold a stack of sheets ( 110, 210 ) supported thereon: wherein each of the plurality of sets of de-stacking means is adapted to selectively engage an uppermost sheet from at least one of the stacking magazines in any desired order either sequentially and/or simultaneously so as to discharge the picked-up sheets onto an out-feed conveyor ( 180, 280 ) in any desired manner either one besides another or otherwise one overlapping the other.

First claim

The invention claimed is:

1. A denesting apparatus, the apparatus comprising:
one or more closed loop conveying tracks, each closed loop conveying track comprising a plurality of sets of a plurality of de-stacking means movingly configured thereon through one or more de-stacking means moving mechanism; and
one or more stacking magazines, each adapted to hold a stack of sheets supported thereon;
wherein each of the plurality of sets of de-stacking means is adapted to selectively engage an uppermost sheet from at least one of the one or more stacking magazines so as to discharge picked-up sheets onto an out-feed conveyor; wherein the denesting apparatus is configured to discharge the picked-up sheets on to an out-feed conveyor in a plurality of manners, including one besides another and otherwise one overlapping the other;
wherein the de-stacking means are selectively engaged by an engagement means having an articulating engagement mechanism;
wherein the articulating engagement mechanism comprises:
a supporting plate adapted to fixedly support one or more de-stacking means thereupon; and
a pivotally movable mounting bracket having a first open end connected to a first articulated mover, a second open end connected to a second articulated mover and a pivotally movable central end connected to the supporting plate; and

wherein a longitudinal movement of the first articulated mover and the second articulated mover towards and/or away from each other enables a generally perpendicular movement of the supporting plate relative to the rail system of the movers.

2. The apparatus of claim 1 , comprising one, or two or more parallel closed loop conveying tracks and wherein de-stacking means moving mechanism includes a plurality of de-stacking lugs movingly configured onto the one, or two or more parallel multiple closed loop conveying tracks through one or more de-stacking movers movingly configured thereon and wherein the de-stacking movers on the parallel closed loop conveying tracks are independently controlled to achieve translation of the picked-up sheet.

3. The apparatus of claim 2 , comprising a powering means for enabling a movement of each of the plurality of movers including the de-stacking movers and stacking movers of the stacking magazines wherein further the powering means for enabling a movement of each of the plurality of movers is selected from a linear motor, servo motors and synchronic and/or asynchronic motor drives.

4. The apparatus of claim 2 , wherein the de-stacking means and the de-stacking means moving mechanism are wirelessly powered and wirelessly controlled.

5. The apparatus of claim 1 , comprising a first powering means for enabling a movement of the closed loop conveying tracks, wherein the first powering means is a linear motor.

6. The apparatus of claim 1 , wherein each of the plurality of sets of de-stacking means is adapted to selectively engage an uppermost sheet from two or more stacks of sheets of at least one of the one or more stacking magazines in any desired order either sequentially or simultaneously so as to discharge the picked-up sheets onto an out-feed conveyor; wherein the denesting apparatus is configured to discharge the picked-up sheets on to an out-feed conveyor in a plurality of manners, including one besides another and otherwise one overlapping the other.
