Definitions

  • the invention relates to a method for producing panels.
  • Laminate panels have been state-of-the-art for quite some time nowadays and can no longer be imagined today in a variety of applications, in particular as a replacement for real wood panels.
  • a particularly large field of application consists in the cladding of walls, ceilings and floors, where from respective wall, ceiling and floor panels, the respective panel is assembled.
  • a floor panel is naturally exposed to much greater loads than, for example, a wall or ceiling paneling.
  • a support plate for example made of a wood material such as MDF, HDF or OSB, provided and this coated with several layers optionally different materials.
  • a decorative layer is applied on a possibly pretreated surface of a wood-based panel, which was provided as the core of the panel to be produced.
  • This can be impregnated, for example, in the form of a printed Paper happen.
  • the paper can also be printed directly on top of the wood-based panel. This can be done by means of pressure rollers or a digital printer.
  • a primer layer can be applied to the surface of the wood-based panel.
  • This decor must, in particular if the panel is to be used as a floor panel, be covered by at least one wear layer.
  • This can for example consist of a paint or a synthetic resin.
  • abrasion-resistant particles eg corundum
  • the layer structure with optionally several synthetic resin layers is finally pressed in a press under pressure and temperature influence, as in EP 1 454 763 B1 to which reference is made in its entirety. Subsequently, the still large-format now coated wood-based panel is divided into individual panels.
  • the coating can also be carried out with lacquer layers, which is then cured by the use of high-energy radiation, for example electron and UV radiation.
  • high-energy radiation for example electron and UV radiation.
  • the large-sized coated carrier plate is divided into panels only after complete curing of the applied layers.
  • a method for producing a panel having the features a) to f) of claim 1 is known in which a primer is first applied to the top of a large-sized wood-based panel.
  • the so-primed wood-based panel is optionally pressed and then divided into individual panels. Only then are the individual panels printed with the desired decor.
  • the problem to be solved according to the invention therefore consists in the fact that, for economic reasons, it is not possible in the current manner in which the laminate panels desired by the end customer are produced Delivery time to satisfy even unusual customer requirements, unless a minimum lot size is required, and that even if the minimum lot size should be reached (for example, in the contract area, so the equipment of large offices or hotels) a longer delivery time must be taken into account, because of course Plant at the panel manufacturer must first be converted accordingly, which is not possible even in the worst order situation within a few hours or days.
  • This problem can be solved by interrupting the chain of the manufacturing process and allowing the dealer, who receives the decoration request of the end customer, to apply the decoration himself to the panels.
  • the dealer can not handle and divide wood-based panels in dimensions of several meters.
  • the invention is therefore based on the object to provide a method by which the possibility is created that a dealer, the raw panels are provided, this can then be provided according to customer requirements with a decor, so that even the smallest order sizes flexible and economical can be produced and at the same time the storage and material costs are reduced.
  • a semi-finished product is first created, which is considered not yet marketable by itself.
  • the dealer can but according to his needs buy semi-finished products and store them with him.
  • the primed raw panels have already been produced by the manufacturer in such a way that they fulfill their technical function. So they are suitable to be interconnected by the connecting and locking means and used as wall, ceiling or floor panels. However, since a wear layer on the surface of the panels is missing, the panels are exposed to the stresses, especially when used as a floor panel, largely unprotected. They also have no decor.
  • the primed raw panels which are also the method described, differ from finished panels only by the lack of decorative layer and the missing at least one wear layer.
  • the end customer can choose from the dealer a decor and a color for the panels, and this printed on the individual prefabricated panels ready and sealed the decor. This allows extremely flexible response to customer requirements, because the decor of both the grain (wood decor) and its color is arbitrarily combinable.
  • the manufacturer of the semi-finished product can produce economically, because only one type of panels is produced, which are then delivered to the various dealers and stored there.
  • the dealer can reduce his inventory of panels, because he can fulfill immediately every wish of the customer.
  • the primer can be applied in the form of a resin-impregnated paper or a directly applied to the top resin.
  • the primer may also be glued to the top of the wood-based panel in the form of a foil, which is coated in particular with a synthetic resin.
  • a resin containing resin can be used.
  • a structure is advantageously impressed into the primer.
  • the primer is advantageously colored.
  • a primer can also be applied to the primer.
  • the connecting and locking means are milled out of the panel.
  • the panels Before the transport-safe packaging, the panels preferably cleaned.
  • a panel according to the invention has a core of a wood-based panel, on whose upper side exclusively a primer in the form of a synthetic resin layer and optionally a primer is applied, which are pressed with the core, wherein on its underside a coating is applied and on opposite side surfaces of the panel mutually corresponding connection and locking devices are provided.
  • the roughness of an upper side of the panel is advantageously less than 20 ⁇ m, particularly preferably less than 10 ⁇ m.
  • the test standard for surface roughness is predominantly ISO 4287-1.
  • a brightness parameter L is greater than 92 for the color of a top of the panel in the CIELAB color space and a red-green value A is between -5 and +5, preferably between -2 and + 2, and a yellow-blue value B is between -15 and +15, preferably between -8 and +8.
  • the standard DIN 6174 serves as the normative basis for this color space.
  • the top of the panel has a structure.
  • the connecting and locking devices may be integrally formed with the wood material board.
  • mutually corresponding connection and locking means are provided on all opposite side surfaces.
  • the invention is based on the idea to make the production of laminate panels, in particular for use as wall, ceiling and floor coverings more flexible, simpler and cheaper.
  • primed panels are produced as semi-finished products.
  • These have a core of wood-based material, the for example, may be formed as OSB, MDF or HDF.
  • This is coated with a primer, which is pressed with the core of the wood-based panel. This results in an easily printable surface that has the required properties to ensure an excellent print image during subsequent printing.
  • the primer in the form of a synthetic resin layer can be applied in various forms to the core of wood-based material.
  • Conceivable for example, the application in the form of a resin-impregnated paper, as applied directly to the top resin layer or in the form of a finish foil, which is laminated, for example, with an adhesive that may contain synthetic resin. All these applied primers lead to a particularly high surface quality.
  • a coating is applied to the lower side of the upper side of the wood-based panel. This can, for example, take over the function of a countermove. This is particularly necessary when a tensile force is exerted parallel to the surface of the wood-based panel on the wood-based panel during drying of the applied primer.
  • the primer is applied, for example, in the form of a coated film which has already been cured, the application of a counterpull may be unnecessary.
  • the coating applied to the underside can then prevent, for example, the absorption of moisture in the underside of the wood-based panel or have only optical reasons.
  • the acceptance of a panel in the market at the end user can be increased in particular by the fact that even on the underside of the panels, which are no longer visible in the installed state, the wood-based panel acting as the core can no longer be seen.
  • the layer structure is pressed. This can be done under pressure and temperature influence. This is especially necessary if at least one of the applied layers should connect to the wood-core material. If the primer is laminated in the form of an already cured film, compression under pressure is sufficient.
  • connecting and locking means may consist of simple tongue and groove profiles or comprise more complicated profiles, with which a locking of two connected panels is ensured, for example, both in the vertical and in the horizontal direction.
  • connecting and locking means can be worked on side edges of panels, in the still separate connection elements, which may for example consist of plastic, are used. For laying or connecting two identical panels, however, it is advantageous if connecting and locking means worked out of the panel, for example, be milled out that two identical panels can be interconnected and locked without additional fasteners.
  • the primed panels produced in this way are finally packed safe for transport. Prior to this, quality control can be carried out to ensure the highest possible quality of the primed panels.
  • the laminate manufacturer produces only primed panels on which no decorative layer must be applied, reduce for the laminate manufacturer both the warehousing and the material costs. There is no need to stock decor papers in different decors, or to provide embossing or embossing plates to make panels with different decors. This significantly reduces both the required storage space and the tied capital. In addition, no changeover times, as all panels have the same primer. As a result, the production plant can work more economically and the production costs are further reduced.
  • the primer is in particular dyed.
  • several colors are possible, examples being white or beige.
  • dyed papers are used as the printing base, whose color corresponds to the brightest shade in the decor to be printed.
  • a white or at least very light primer is advantageous.
  • any other color is also conceivable as a primer.
  • a structure can already be introduced into the primer. This is advantageously done when pressing the layer structure, in particular by embossing plates or embossing rollers used.
  • pre-primed panels produced in this way generally have a very smooth surface.
  • the surface is homogeneous and, if the primer is colored, good coverage. This is very important in combination with a very low defect frequency due to surface defects or dirt particles, in particular for digital printing in which the pre-primed panel is printed directly by means of a digital printer.
  • a colored wood-based panel can at least partially take over the function of a primer.
  • the paint When the wood-based panel or primer is colored, it is advantageous for the paint to have a brightness parameter L greater than 92, a red-green value A between -5 and +5, preferably between -2 and +2 and a yellow-blue Value B is between -15 and +15, preferably between -8 and +8.
  • the values given describe colors in the CIELAB color space. The normative basis of this color space is DIN 6174.
  • the color of the primer or the dyed wood-based panel should correspond to the brightest shade in the decor to be applied. If this, as in the present case, is not yet known, a particularly bright, in particular white, surface color naturally offers itself.
  • Such pre-primed panels are stored at the laminate manufacturer in a central warehouse, such as a high-bay warehouse. Previously, they can in particular be cleaned and packaged in such a way that they can be directly printed or processed in the further processing plant without the panels having to be cleaned there again. However, this only has to be maintained for a single type of panel, so that a space-intensive storage of panels with different decors, different surface structures or different surface finishes is no longer necessary.
  • the primed panels are then transported to a further processing plant.
  • This may, for example, be a franchise operation associated with the laminate manufacturer, a hardware store, an interior decorator, a retailer or a floor publisher.
  • a decorative layer is applied with a decor according to direct customer request to the primer or primer and covered by at least one wear layer.
  • the application of the decorative layer on the primer or the primer can be done in different ways.
  • the decorative layer can be printed directly onto the primer or the primer.
  • the pre-primed panel passes through a printing unit, which is advantageously a digital printer. This makes it possible, in particular different designs quickly and easily to print successively on different panels without having to convert the printing unit to the new decor.
  • the printing unit can be made small and compact and thus space and cost.
  • a decor paper which can be kept in the form of large rolls, be printed with a decor and then laminated as a decorative layer on the primer or the primer.
  • the decorative layer should be covered by at least one wear layer.
  • the number and type of applied wear layers depends heavily on the intended location of the so decorated panels. Especially with wall and ceiling panels, it is often sufficient if the at least one wear layer covers the decorative layer wipe-resistant. However, if the printed panels are used as a floor panel, they are exposed to a significantly higher load. In this case, in particular a plurality of wear layers can be applied, to which additives are added which increase an abrasion and / or scratch resistance of the upper side of the then finished panels.
  • the at least one wear layer can consist of a synthetic resin and be cured after application by compression under the influence of pressure and temperature.
  • a structure which corresponds in particular to the decoration of the decorative layer can also be embossed into the at least one wear layer so as, for example, to make the natural appearance of a real wood decoration more realistic.

  • the further reservoirs 130 include, for example, hardener, corundum to increase the abrasion resistance of the finished coated panel and other additives that are selected depending on the intended use of the then finished panel.
  • various panel formats can also be processed in the coating apparatus 124.
  • the panels 102 to be coated are guided over guide elements 122.
  • a possible layer structure consists of several layers of radiation-curable lacquer.
  • two layers of an antiabrasive UV basecoat are applied with a roller system in an application amount of, for example, 35 g / m 2 onto the top surface of the panel 102 to be coated.

  • the previously applied lacquer layer is cured by means of UV or electron beams.
  • the various wear layers which may in particular also consist of a synthetic resin, are applied directly one after the other without drying the wearing layer previously applied by an application device 126.
  • An applicator 126 in the form of rollers can be operated both in the same and in the opposite direction. In order to coat as many panels 102 as possible in a given time, high feed rates of such applicators 126 are preferred. In particular, feed speeds of between 10 m / min and 30 m / min are suitable.
  • these application devices 126 can also be in the form of an injection or spray painting device, a digital print head, a casting head or a vacuum be.
  • Abrasion-resistant particles, for example corundum, or other additives may be present in each applied layer. These depend on the later use of the then finished panel.
  • the wear layers applied in the coating device 124 which may for example be in the form of a lacquer, are only gelatinized by high-energy rays, for example electrons or UV rays.
  • a stamping device 134 a structure is embossed in the upper side of the coated panel, that is to say the useful layers. This structure corresponds in particular to the selected decor of the decorative layer applied in the printing unit 110.
  • the embossing of the structure can be done, for example, by means of a structured roller, a structured belt or a structure-regulating paper or a structure-forming film.
  • an overlay paper sheet can be placed and then pressed in a short-cycle press under the action of pressure and heat.
  • structures are provided in particular in the press plates, which impress during pressing into the top of the panel 102.
  • the panel 102 passes through a second curing device 136.
  • the optionally-gelled wear layers are completely cured so that a surface suitable for the respectively selected use of the panel 102 is produced.
  • the panels 102 pass through a quality assurance 138, possibly a label 140 or the like, if necessary, in addition also a cleaning device and are finally packed and can be taken by the customer.
  • the electronic data processing device 114 is coupled to the second electronic data processing device 128.
  • a customer will be given in the processing operation then for example by means of a program different choices. He can choose, for example, whether the panel 102 private or commercial, to be used in the dry or wet area, with references to various commercial use classes are given. In addition, the customer can decide whether the panel to be coated 102 will later be a floor, wall or ceiling panel. This information is important for the wear layers to be applied in the coating device 124. In a device for refining a panel, the useful layers with the required additives and additives are then automatically applied to achieve a certain degree of wear, for example AC3 according to DIN EN 13329. Painting and curing take place automatically.
  • the customer can also choose the format of the panel and the thickness of the support plate as well as the desired decor and possibly a structure to be impressed.
  • both the printing unit 110 and the coating device 124 can be set to the thickness and the format of the panels 102 to be coated.
  • the panels can only be placed in a cardboard box or by means of a film, such as a shrink film, also protected against splashing water.
  • the customer can decide, for example, whether he would like to take the finished panels with him or pick them up at a later time or whether they should be delivered by a third-party company.
  • An installation option by a specialist company is also conceivable.
  • the customer may, for an additional charge, select warranty and warranty options and, if necessary, decide whether to buy or rent the panels.
  • the coating and the curing of the paint layers can be done automatically. Since the lacquers or resin layers used, which are applied as useful layers, can be optimized for this application, in particular with regard to their viscosity, a smooth application without increased or minimum lacquer applications at the beginning and at the end of the panels 102 to be coated can be ensured. In order to protect the connecting and locking elements already formed on the panels 102, masks may be used which prevent soiling or contamination of these connecting and locking elements. In particular, when curing lacquer layers applied by the adjustment of the radiation intensity, the adhesion of the individual layers to each other and the final curing can be realized and guaranteed. For multiple jobs, the corresponding part of the installation, ie coating device 124 and first curing device 132 and second curing device 136, can be run through multiple times.
  • the method described has a number of advantages. After completion of the surface, the customer can immediately take the finished product in the desired quantity and quality. This solves in particular the problem of small quantities for the laminate panel manufacturer since he only has to manufacture one type of panel, namely pre-primed and structured panels, if necessary in different dimensions. Since the connecting and locking means are milled in this process on pre-primed panels or worked in any other form, the resulting milling waste is reduced in particular by the fact that on the pre-primed panels no decorative paper or overlay paper is applied. As a result, the production costs are significantly reduced. In addition, the described method significantly reduces transport damage or transmission errors in orders, because the customer can stand directly in front of the device and enters his wishes. A transfer of an order to a laminate manufacturer is no longer necessary.
