Abstract

A method for the refinement of a panel and an apparatus for the refinement of a panel according to a method of this type. The method for the refinement of a panel includes: unpacking of a panel having a core made from wood material from a transport-safe packaging, a grounding in the form of at least one synthetic resin layer pressed together with the core and, if appropriate, a primer being arranged on a top side of the core, and a coating being arranged on a core underside lying opposite the top side of the core, and connection and locking means being attached to at least two mutually opposite side faces; application of a decorative layer having a decoration to the grounding or primer; and application of at least one wear layer to the decorative layer.

First claim

The invention claimed is:

1. An apparatus used outside of laminate floor manufacturing facilities for finishing and refinement of an unfinished panel manufactured by the laminate floor manufacturing facilities and transported to a third party for finishing and refinement of the panel, the panel which is unfinished at the floor manufacturing facilities has a core of wood material, the panel has a base coat in the form of at least one synthetic resin layer which is pressed with the core and possibly a primer layer on a top side and a coating on a bottom side which lies opposite the top side, the apparatus for further finishing and refinement of the partly manufactured panel comprising:
a printing unit for printing a decorative pattern directly onto the base coat or the primer layer of the unfinished panel,
an electronic data processing device with an input device for inputting a selection of a decorative pattern which is stored in a data memory in the form of electronic data from a plurality of available decorative patterns,
an electric controller which is set up to read the selected decorative pattern from a data memory and to actuate the printing unit in such a way that the selected decorative pattern is printed onto the unfurnished panel,
a display device, via which available decorative patterns can be displayed to the dealer or a customer of the finished panel,
a coating apparatus having a various reservoirs arranged downstream of the printing unit to provide a coating, which is a wear layer of a synthetic resin or lacquer layer, directly over the decorative pattern of the unfinished panel, and
a curing device and an embossing device arranged downstream of the coating apparatus to provide an embossing in the coating and to cure the unfinished panel into a completed panel;
a second data processing apparatus for controlling the coating apparatus, wherein:
the second data processing apparatus has a merge program by which composition of individual wear layers is controlled in the various reservoirs by mixing their contents to form a desired wear layer;
a first of the reservoirs contains a basic substance of each individual wear layer comprising a synthetic resin or a lacquer; and
further reservoirs contain one of hardeners, corundum for increasing abrasion resistance, and additives, and
wherein the curing device is a first high energy radiation curing device and a second high energy radiation curing, the first curing device positioned downstream from the embossing device and the second curing device positioned upstream from the embossing device.

2. The apparatus according to claim 1 , wherein the printing unit is a digital printer.

3. The apparatus according to claim 1 , further comprising a cleaning apparatus arranged upstream of the printing unit.

4. The apparatus according to claim 3 , wherein the cleaning apparatus is structured to clean a surface of the panels of dirt residues and dust.

5. The apparatus according to claim 1 , wherein the electronic data processing device comprises a camera.

6. The apparatus according to claim 1 , further comprising a CD-ROM drive.

7. The apparatus according to claim 1 , further comprising a scanner.

8. The apparatus according to claim 1 , wherein the coating apparatus has three application apparatuses.

9. The apparatus according to claim 1 , wherein each application apparatus is configured in the form of a roller system.

10. The apparatus according to claim 1 , wherein each application apparatus is configured as a spraying or spray-painting device.

11. The apparatus according to claim 1 , wherein the embossing device has a structured roller, a structured belt, a structure-lending paper or a structure-lending film.

12. The apparatus according to claim 1 , further comprising an acceleration section arranged upstream of the printing unit structured to feed the panel to the printing unit.

13. The apparatus according to claim 12 further comprising guide elements which keep the panels exactly in alignment when the printing unit prints the decorative pattern.

14. The apparatus according to claim 12 , wherein the decorative pattern is updated online.

15. The apparatus according to claim 1 , further comprising guide elements inside the coating apparatus.

16. The apparatus according to claim 1 , further comprising a digitally activated printing head to apply lacquer as a wear layer on the panel.

17. The apparatus according to claim 16 , wherein the coating apparatus comprises the digitally activated printing head to apply the lacquer at specific locations of the panel to generate structure-forming depressions and elevations.

18. The apparatus according to claim 17 , wherein:
the electronic data processing device includes at least one of a scanner and a camera;
the printing unit includes printing heads and guide elements guide the panel into the printing unit; and
the coating apparatus includes: guide elements inside to guide the panels in the coating apparatus and a roller system which is configured to apply radiation-hardenable lacquer on the topside of the panel which is hardened by the curing device.

19. The apparatus according to claim 17 , wherein:
the electronic data processing device includes at least one of a scanner and a camera;
the printing unit includes printing heads and guide elements guide the panel into the printing unit; and
the coating apparatus includes an applicator device comprising a splash or spray-lacquering device, a digital printing head, a casting head or a vacuum apparatus.
