A device for assembling large flexible panel layers into press packs, for the production of layered pressed panels, the device including a plurality of parallel layer collecting lines with two layer stacks each, arranged on opposite sides of a transversely extending press pack assembly conveyor. The latter advances from collecting line to collecting line, as a collecting carriage in each collecting line alternatingly collects panel layers from its two layer stacks. The collecting carriages are moved by means of crank drives; the layer stacks are adjustably positioned under light beam position markers.

A device for collecting large flexible panel layers, including very thin panel layers, from separate layer stacks and for assembling them into press packs, ready for transfer to a panel press, for the production of layered press panels, for example, the device comprising in combination: a plurality of parallel layer collecting lines arranged side-by-side and uniformly spaced from one another; each layer collecting line having at least one layer stack associated therewith; a press pack assembly conveyor having an endless conveyor belt running transversely to the layer collecting lines and past all layer stacks at a short distance therefrom; and means for driving the press pack assembly conveyor in a stepping motion, the distance of each step being equal to the spacing between the layer collecting lines; and wherein the press pack assembly conveyor defines a press pack collecting station for each layer collecting line; each layer collecting line includes: a collecting carriage; means for guiding the collecting carriage for shuttle movements between its layer stack and its collecting station on the press pack assembly conveyor; a suction bank on the collecting carriage capable of singulating a panel layer from the layer stack and of transferring it, under the movement of the collecting carriage, to the collecting station; and a horizontal crank drive connected to the collecting carriage for the creation of said shuttle movements; the crank drives of all layer collecting lines operate in unison; the suction bank of each carriage is guided for vertical movements in relation to the carriage and each carriage includes means for moving the suction bank vertically; at least one of the collecting lines has two layer stacks arranged on opposite sides of the press pack assembly conveyor, in alignment with and identically spaced from the collecting station on said conveyor; the collecting carriage of said line executes shuttle movements for the alternating pickup and collection of panel layers from both of said layer stacks; the collecting carriage guide means of said line includes overhead guide rails extending across said conveyor; the crank drive for the collecting carriage of said line has a crank radius for a carriage stroke which is equal to the distance to be travelled by a panel layer between its stack and the collecting station; said crank drive further includes a mechanism for creating a supplemental stroke of the collecting carriage which is equal to the distance between the point of release of one panel layer on the collecting station and the point of pickup of the next panel layer on the opposite layer stack, said supplemental stroke mechanism being so related to the crank drive that its effect on the movement of the suction bank on the collecting carriage is to longitudinally shift its crank-generated stroke by the supplemental stroke; and the suction banks on the collecting carriages are arranged to engage the panel layers in the area of the edges which are located nearest to the press pack assembly conveyor, lifting only an edge portion of each panel, as the suction banks move vertically, and transferring each panel from its stack to a collecting station on the press pack assembly conveyor by pulling the panel sideways from its stack, as the collecting carriage executes its shuttle movement.
