Description
Verfahren und Vorrichtung zur Bearbeitung von Holzwerkstoffplatten Method and device for processing wood-based panels
Die Erfindung betrifft ein Verfahren zur Bearbeitung von Holzwerkstoffplatten nach dem Oberbegriff des Anspruches 1 sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for processing wood-based panels according to the preamble of claim 1 and an apparatus for performing the method.
Aus der WO 99/51361 ist es bekannt, eine Holzwerkstoffplatte, insbesondere eine Spanplatte (welche zunächst als Rohplatte vorliegt) in einer Fertigungsanlage zunächst einem Fräsvorgang und dann einem Schleifen zu unterziehen. Sodann tragen Profϊlwalzen eine schnell aushärtbare Verfüllmasse - hier eine Lackmasse - auf, die mit Formrollen eingespachtelt und geglättet wird. Mit einem geeigneten Verfahren, z.B. mittels einer UV-Trocknung, härtet die Masse aus. Daraufhin erzeugen Profilschleifaggregate die endgültige Form der Kante (z.B. eine Abrun- dung) mit guter Oberflächenqualität. Die Holzwerkstoffplatten werden sodann mit Bürsten gereinigt.From WO 99/51361 it is known to first subject a wood-based panel, in particular a particle board (which is initially in the form of a raw panel), to a milling process and then a grinding in a production system. Then profile rollers apply a quickly hardenable filler compound - here a lacquer compound - which is filled in and smoothed with form rollers. With a suitable method, e.g. by means of UV drying, the mass hardens. Then profile sanding units produce the final shape of the edge (e.g. a rounding) with good surface quality. The wood-based panels are then cleaned with brushes.
Ein weiteres Verfahren zum Vorbehandeln des Kantenbereiches mit einer Verfüllmasse ist aus der DD 240 523 AI bekannt.Another method for pretreating the edge area with a filling compound is known from DD 240 523 AI.
Diese Verfahren haben sich an sich bewährt. Nicht optimal ist nach dem Stand der Technik aber die weitere Verarbeitung der Holzwerkstoffplatte. Üblicherweise wird die Platte oder das Dekorpapier zunächst vollständig mit Klebstoff beschichtet. Dann werden diese beiden Elemente zusammengefügt, wobei das Dekorpapier auch um den Kantenbereich der vorbehandelten Platte gelegt wird. Dabei genügt aber insbesondere die Qualität der verklebten Oberfläche, insbesondere auch im Kantenbereich, oftmals nicht den gestellten Ansprüchen.These methods have proven themselves. According to the state of the art, however, the further processing of the wood-based panel is not optimal. Usually, the plate or decorative paper is first completely coated with adhesive. Then these two elements are put together, the decorative paper also being placed around the edge area of the pretreated plate. However, the quality of the bonded surface, especially in the edge area, often does not meet the requirements.
Die Erfindung zielt daher darauf ab, das gattungsgemäße Verfahren derart weiter- zuentwickeln, daß die Qualität der verklebten Oberfläche, insbesondere auch im Kantenbereich, verbessert wird.The invention therefore aims to further develop the generic method in such a way that the quality of the bonded surface, in particular also in the edge area, is improved.
BESTATIGUNGSKOPIE Die Erfindung soll ferner eine geeignete Vorrichtung zur Durchführung des Verfahrens schaffen.BESTATIGUNGSKOPIE The invention is also intended to provide a suitable device for carrying out the method.
Die Erfindung erreicht dieses Ziel in Hinsicht auf das Verfahren durch den Ge- genstand des Anspruches 1 und in Hinsicht auf die Vorrichtung durch den Gegenstand des Anspruches 11.The invention achieves this aim with regard to the method by the subject matter of claim 1 and with regard to the device by the subject matter of claim 11.
Sie schafft ein Verfahren zur Bearbeitung von Holzwerkstoffplatten, vorzugsweise Spanplatten mit einem offenporigen Kantenbereich, welcher mit einer Vergü- tungsmasse verfüllt und/oder abgedeckt ist, mit folgenden Schritten:It creates a method for processing wood-based panels, preferably chipboard, with an open-pore edge area that is filled and / or covered with a coating compound, with the following steps:
- Auftragen eines ersten Klebstoffes, insbesondere auf die Ober- und/oder Unterseite der Holzwerkstoffplatte oder auf ein Dekorpapier, wobei der Kantenbereich der Holzwerkstoffplatte oder der Randbereich des Dekorpapiers, welcher zum Ummanteln des Kantenbereichs der Holzwerkstoffplatte bestimmt ist, nicht oder nur in einem Übergangsbereich mit dem ersten Klebstoff bedeckt wird;- Applying a first adhesive, in particular on the top and / or bottom of the wood-based panel or on a decorative paper, the edge region of the wood-based panel or the edge region of the decorative paper, which is intended for sheathing the edge region of the wood-based panel, not or only in a transition region covering the first adhesive;
- Auftragen eines zweiten Klebstoffes auf den Kantenbereich der Holzwerkstoffplatte oder auf den Randbereich des Dekorpapiers (oder einer Dekorfolie), welcher zum Ummanteln des Kantenbereichs der Holzwerkstoffplatte be- stimmt ist;Applying a second adhesive to the edge area of the wood-based panel or to the edge area of the decorative paper (or a decorative film), which is intended to encase the edge area of the wood-based panel;
- Kaschieren der Ober- und/oder der Unterseite der Holzwerkstoffplatte mit dem Dekorpapier;- Laminating the top and / or bottom of the wood-based panel with the decorative paper;
- Ummanteln des Kantenbereichs mit dem Randbereich des Dekorpapiers, der mit dem zweiten Klebstoff versehen ist.- Wrapping the edge area with the edge area of the decorative paper, which is provided with the second adhesive.
Der zweite Klebstoff ist dabei in irgendeiner Form anders als der erste Klebstoff beschaffen.The second adhesive is in some form different from the first adhesive.
Die Erfindung eignet sich insbesondere für Spanplatten, aber auch für andere Holzwerkstoffplatten wie mitteldichte Faserplatten ohne vergütete Kanten oder gl.. Die Erfindung schafft ferner eine Vorrichtung zur Durchführung des Verfahrens, welche folgendes aufweist:The invention is particularly suitable for chipboard, but also for other wood-based panels such as medium-density fiberboard without tempered edges or smooth. The invention also provides an apparatus for carrying out the method, which has the following:
- wenigstens eine erste Auftrageinrichtung zum Auftragen eines ersten Klebstoffes auf die Ober- und die Unterseite der Holzwerkstoffplatte; - wenigstens eine zweite Auftrageinrichtung zum Auftragen eines zweiten Klebstoffs, insbesondere Heißschmelzklebers auf den Randbereich eines Dekorpapiers;- At least one first application device for applying a first adhesive to the top and bottom of the wood-based panel; - At least one second application device for applying a second adhesive, in particular hot melt adhesive, to the edge area of a decorative paper;
- wenigstens eine den zwei Auftrageinrichtungen nachgeschaltete Kaschiereinrichtung zum Kaschieren der Ober- und/oder Unterseite der Holzwerkstoffplat- te mit dem Dekorpapier, und- At least one laminating device downstream of the two application devices for laminating the top and / or bottom of the wood-based panel with the decorative paper, and
- eine vorzugsweise der Kaschiereinrichtung nachgeschaltete Ummantelungsein- richtung zum Ummanteln des Kantenbereichs der Holzwerkstofφlatte.- A sheathing device, preferably downstream of the laminating device, for sheathing the edge area of the wood-based panel.
Unter den Begriff „Dekorpapier" sind hier sowohl die eigentlichen Dekorpapiere im engeren Sinne als auch Dekorfolien aus Kunststoff und dergleichen zu fassen.The term "decorative paper" includes both the actual decorative papers in the narrower sense and decorative films made of plastic and the like.
Mit Hilfe der Erfindung wird die Qualität der verklebten Oberflächen nicht nur im Kantenbereich sondern auch im Bereich der übrigen Oberflächen an der Ober- und/oder der Unterseite der Holzwerkstoffplatte deutlich erhöht, da sowohl für die Oberfläche als auch für den Kantenbereich jeweils separat der optimale Klebstoff ausgewählt und eingesetzt wird. Insbesondere kann auch im Bereich der Kanten eine hohe, mit der Qualität der Oberfläche vergleichbare Qualität erreicht werden. Am vorteilhaftesten ist es, wenn der erste Klebstoff auf die Plattenober- und/oder Unterseite und der zweite Klebstoff auf das Dekorpapier aufgebracht wird.With the help of the invention, the quality of the bonded surfaces is not only significantly increased in the edge area but also in the area of the other surfaces on the top and / or the underside of the wood-based panel, since the optimal adhesive is separately available for both the surface and the edge area is selected and used. In particular, a high quality comparable to the quality of the surface can also be achieved in the area of the edges. It is most advantageous if the first adhesive is applied to the top and / or bottom of the plate and the second adhesive to the decorative paper.
Im Bereich der Oberfläche an der Ober- und/oder Unterseite der Holzwerkstoffplatte werden bevorzugt nacheinander ein Härter und dann ein Harnstoffkleber aufgetragen, wohingegen es sich im Bereich der Kante als besonders vorteilhaft erwiesen hat, einen Heißschmelzkleber einzusetzen. Dieser wird vorzugsweise nicht mit auf die Spanplatte aufgetragen, sondern auf den Randbereich des Dekorpapiers, welcher zum Abdecken des Kantenbereiches der Holzwerkstoffplatte bestimmt ist. Die Reihenfolge des Auftrags von Härter kann auch umgekehrt werden oder gleichzeitig (bzw. in einer Vorrichtung) erfolgen, zudem ist es auch denkbar, den Härter u.U. auf das Dekorpapier aufzutragen.A hardener and then a urea adhesive are preferably applied in succession in the area of the surface on the top and / or underside of the wood-based panel, whereas in the area of the edge it has proven particularly advantageous to use a hot-melt adhesive. This is preferably not applied to the chipboard, but to the edge area of the decorative paper, which is intended to cover the edge area of the wood-based panel. The order of application by Härter can also be reversed or simultaneously (or in one device), it is also conceivable to apply the hardener to the decorative paper.
Im Bereich der Fläche ergibt sich dadurch eine duroplastische Verklebung, die aufgrund des Einsatzes der üblichen Kaschiervorrichtungen wie auch Kalandern zu einer deutlich besseren Qualität der verklebten Oberfläche führt.In the area of the surface, this results in a thermosetting bond, which leads to a significantly better quality of the bonded surface due to the use of the usual laminating devices as well as calenders.
Im Bereich der Kante ergibt sich ebenfalls ein entsprechender Vorteil, denn die Qualität der Kante wird verbessert. Es ergibt sich eine besonders glatte sowie beanspruchbare, verschleißfeste Oberfläche, die für hochwertige Möbel eingesetzt wird, wobei die Ummantelung mit geringsten Klebermengen erfolgen kann.There is also a corresponding advantage in the area of the edge, since the quality of the edge is improved. The result is a particularly smooth and resilient, wear-resistant surface that is used for high-quality furniture, whereby the covering can be done with the smallest amount of adhesive.
Es ist ferner möglich, durch die spezielle Auswahl der Klebstoffe für den Flächenbereich und den Kantenbereich dünnste Dekorpapiere einzusetzen.It is also possible to use the thinnest decorative papers for the surface area and the edge area due to the special selection of the adhesives.
In der Praxis zeigt sich, daß der Übergang zwischen Fläche und Kantenbereich ohne erkennbare Formveränderung ausgebildet ist. Es treten i.allg. weder Beulen noch Ecken oder Glanzgradunterschiede zwischen der Oberfläche an der Ober- und Unterseite und dem Kantenbereich auf.In practice, it can be seen that the transition between the surface and the edge area is formed without any discernible change in shape. Generally. neither bumps nor corners or differences in gloss level between the surface on the top and bottom and the edge area.
Dazu ist es besonders vorteilhaft, wenn die beiden Klebstoffe derart aufgetragen werden, dass sie sich - im zusammengefügten Zustand - bereichsweise, z.B. in einem einige wenige mm breiten Streifen - aber nicht vollständig überlappen. Dies führt zu einer guten Verformbarkeit und damit zu einem besonders guten Über- gang zwischen dem Kantenbereich und der Ober- und/oder Unterseite derFor this purpose, it is particularly advantageous if the two adhesives are applied in such a way that - in the assembled state - they partially, e.g. in a strip a few mm wide - but do not overlap completely. This leads to good deformability and thus to a particularly good transition between the edge area and the top and / or bottom of the
Holzwerkstoffplatte. Alternativ kann aber auch versucht werden, eine möglichst klare Trennzone zwischen den Bereichen auszubilden.Wood panel. Alternatively, however, an attempt can also be made to form the clearest possible separation zone between the areas.
Ebenfalls vorteilhaft ist, daß mittels der Erfindung der Einsatz von Rollen als Formwerkzeuge möglich wird. Hier ist der Vorteil, daß die Rollen oder nicht stillstehenden Formwerkzeuge das Dekor nicht verkratzen können, wobei natürlich der Einsatz von Profilschuhen o.dgl., also von stillstehenden Formwerkzeugen prinzi- piell möglich bleibt. Es muss kein profilspezifisches Werkzeug eingesetzt werden, obwohl der Einsatz eines solchen Werkzeugs natürlich theoretisch denkbar ist.It is also advantageous that the use of rollers as molding tools is possible by means of the invention. The advantage here is that the rollers or molds that are not at a standstill cannot scratch the decor. remains possible. No profile-specific tool has to be used, although the use of such a tool is of course theoretically conceivable.
Weitere vorteilhafte Ausgestaltungen sind den übrigen Unteransprüchen zu ent- nehmen.Further advantageous configurations can be found in the remaining subclaims.

This can be done, for example, in the manner of WO 99/51361 Apply a quickly curable lacquer to the open-pore edge area and then dry using UV drying.
Die derart vorbehandelte und gereinigte Holzwerkstofφlatte wird unmittelbar nach dem Aushärten und Reinigen oder aber nach einem Zwischenstapeln und Lagern der Platten dem Verfahrensschritt der Figur 2 zugeführt. Das Verfahren kann damit unabhängig von dem Verfällen der Holzwerkstofφlatte in einer zweiten separaten Fertigungslinie durchgeführt werden.The pretreated and cleaned wood-based panel is fed to the method step of FIG. 2 immediately after curing and cleaning or after intermediate stacking and storage of the panels. The method can thus be carried out in a second separate production line regardless of the deterioration of the wood-based panel.
Figur 2 zeigt schematisch das Auftragen von Härter 2 auf die Oberseite 3 derFigure 2 shows schematically the application of hardener 2 on the top 3 of the

Das Auftragen des Härters 2 erfolgt hier mittels einer ersten Walzenauftragsmaschine 5, die schematisch auch in Figur 1 zu erkennen ist.The hardener 2 is applied here by means of a first roller application machine 5, which can also be seen schematically in FIG. 1.
Sodann wird der Härter 2 angetrocknet (hier nicht detailliert dargestellt) und gemäß Fig. 3 einer zweiten Walzenauftragsmaschine 6 zugeleitet, welche auf der Oberseite 3 der Spanplatte 1 auf den Härter einen ersten Klebstoff, hier einen Hamstoffharzleim 7 aufträgt. Der Kantenbereich 4 bleibt wiederum frei bzw. wird nicht vom Hamstoffharzleim 7 mit bedeckt. Sodann wird auch der Hamstoffharzleim 7 angetrocknet (nicht dargestellt).Then the hardener 2 is dried (not shown in detail here) and fed to a second roller application machine 6 according to FIG. 3, which applies a first adhesive, here a urea resin glue 7, to the hardener on the top 3 of the particle board 1. The edge area 4 again remains free or is not covered by the urea resin glue 7. The urea resin glue 7 is then also dried (not shown).

Im Anschluss an diesen Vorgang wird das Dekorpapier 9 von einer Druckwalze 8 gegen die Oberfläche 3 der Spanplatte 1 gedrückt. Das Kaschieren der Oberseite 3 und der Unterseite 15 kann gemäß Fig. 5 mit einer oder mehreren beheizten Druckwalzen 8 (Kalander) mit handelsüblicher Dekorfolie oder einem handelsüblichen Dekorpapier 9 erfolgen.Following this process, the decorative paper 9 is pressed by a pressure roller 8 against the surface 3 of the chipboard 1. The upper side 3 and the lower side 15 can be laminated according to FIG. 5 with one or more heated printing rollers 8 (calenders) with commercially available decorative film or with a commercially available decorative paper 9.
Wichtig ist, daß lediglich die Ober- und/oder die Unterseite bzw. -flächen der Spanplatte 1 kaschiert wird/werden. Der Kantenbereich 4 bleibt in diesem Verfahrensschritt unbearbeitet, d.h. im Kantenbereich steht von der Spanplatte ein Randbereich 13 des Dekorpapiers 9, der mit dem Heißschmelzkleber 11 beschichtet ist, frei nach außen vor.It is important that only the top and / or the underside or surfaces of the chipboard 1 is / are laminated. The edge area 4 remains unprocessed in this process step, i.e. in the edge area, an edge area 13 of the decorative paper 9, which is coated with the hot-melt adhesive 11, projects freely outward from the chipboard.
In einem letzten Verfahrensschritt, der in Figur 6 dargestellt ist, wird auch der Randbereich 13 des Dekoφapiers 9 an den Kantenbereich 4 angedrückt. Dies kann mittels einer Ummantelungseinrichtung 14 erfolgen, die hier lediglich schematisch dargestellt ist und mit Druckrollen oder Profilschuhen versehen sein kann.In a last method step, which is shown in FIG. 6, the edge area 13 of the decorative paper 9 is also pressed onto the edge area 4. This can be done by means of a sheathing device 14, which is only shown schematically here and can be provided with pressure rollers or profile shoes.
Danach wird noch jeweils der zwangsweise nicht zu vermeidende Randüberstand des Dekorpapiers (hier nicht dargestellt) durch Schleifen, Fräsen oder einen sonstigen Trennvorgang entfernt.Then the inevitably unavoidable overhang of the decorative paper (not shown here) is removed by grinding, milling or another separation process.
Sodann werden ggf. in einer nachgeschalteten Trennstation (hier nicht dargestellt) die Dekorfolien 9 zwischen den Holzwerkstoffplatten getrennt. Es ist optional möglich (nicht dargestellt), dass das Dekorpapier 9 vor dem Kaschieren in der Breite beschnitten wird. Die einzelnen Holzwerkstofφlatte können zudem auch vor oder hinter der Ummantelungseinrichtung 14 einem oder mehreren Nachdruck- oder Glättekalandern zugeführt werden (hier nicht dargestellt). BezugszeichenlisteThen, if necessary, the decorative foils 9 are separated between the wood-based panels in a downstream separation station (not shown here). It is optionally possible (not shown) that the decorative paper 9 is trimmed in width before lamination. The individual wood-based panels can also be fed in front of or behind the casing device 14 to one or more holding or smoothing calenders (not shown here). LIST OF REFERENCE NUMBERS
