Description

Die Erfindung betrifft ein Verfahren zum Herstellen von Brettschichtholz bzw. Balkenschichtholz, bei dem Bretter bzw. Balken mehrlagig zu Schichtholz verleimt werden und das verleimte Schichtholz anschließend zur Erzielung des gewünschten Maßes gehobelt und zur Erzielung der gewünschten Oberflächengüte erforderlichenfalls an Fehlstellen lokal repariert wird.The invention relates to a method for producing glulam or laminated timber, in which boards or beams are multilayered Laminated wood are glued and then the glued laminated wood planed to achieve the desired size and to achieve the desired surface quality if necessary locally at defects is repaired.

Beim üblichen Verfahren, beispielsweise nach DIN 1052, werden die Werkstücke (Brettschichtholz oder Balkenschichtholz) in einem ersten Prozeßschritt gehobelt und anschließend werden in einem zweiten Prozeßschritt Oberflächenfehler ausgebessert. Das Ausbessern der Oberflächenfehler kann hierbei insbesondere so vonstatten gehen, daß die gehobelten Werkstücke von entsprechend geschultem Personal visuell kontrolliert werden und im Falle von Oberflächenfehlern wie insbesondere Harzgallen, Ausfalläste, Waldkante, kleine Ausrisse und eingewachsene Rinde, also im Falle von optischen Fehlern und kleinen Beschädigungen, im Bereich dieser Oberflächenfehler je nach geforderter Oberflächenqualität lokal repariert werden. Eine solche Reparatur kann beispielsweise dadurch erfolgen, daß die Fehlstellen mittels handgehaltener Werkzeuge an den Fehlstellen ausgefräst werden und entsprechende Flickstücke ( ein- oder mehrschiffige Harzgallenflicken, Flickleisten in jeweils unterschiedlichen Längen und Dimensionen, Naturersatzäste, Querplattl usw.) eingesetzt werden. Auch können geeignete Füllstoffe wie Holzkitt, Schmelzkleber, PUR-Filler usw. zum Einsatz kommen.In the usual method, for example according to DIN 1052, the Workpieces (glulam or beams) in a first Process step planed and then in a second Process step surface defects corrected. Mending the Surface defects can occur in particular in such a way that the planed workpieces visually by appropriately trained personnel are checked and in the case of surface defects such as in particular Harzgallen, drop branches, forest edge, small tears and ingrown Bark, in the case of optical defects and minor damage, in the area of these surface defects depending on the required Surface quality can be repaired locally. Such a repair can take place, for example, in that the imperfections by means hand-held tools are milled out at the defects and Corresponding patches (single or multi-aisle resin gall patches, Patch bars in different lengths and dimensions, Natural replacement branches, cross plates, etc.) are used. Can too suitable fillers such as wood putty, hot melt adhesive, PUR filler etc. for Come into play.

Nach dem Einsetzen der Flickstücke bzw. dem Aushärten der Füllstoffe ist es zum Erzielen einer gleichmäßigen Oberfläche erforderlich, die reparierten Bereiche durch Nachhobeln oder Nachschleifen nochmals nachzuarbeiten, was ebenfalls mittels handgehaltener Werkzeuge erfolgt.After inserting the patches or curing the fillers it is necessary to achieve a uniform surface that repaired areas by planing or regrinding again rework what is also done with hand-held tools.

Der Erfindung liegt die Aufgabe zugrunde, das gattungsgemäße Verfahren so weiterzubilden, daß eine noch höhere Oberflächenqualität des Endprodukts erzielt werden kann.The invention has for its object the generic method to develop so that an even higher surface quality of the End product can be achieved.

Diese Aufgabe wird erfindungsgemäß im wesentlichen durch folgende Verfahrensschritte gelöst: Erste Kontrolle der Oberflächengüte des verleimten Schichtholzes nach dem Verleimen sowie Vorreparieren des Schichtholzes, Hobeln des vorreparierten Schichtholzes auf das gewünschte Endmaß, Endkontrolle der Oberflächengüte des vorreparierten und gehobelten Schichtholzes und gegebenenfalls Nachreparieren ausgewählter Bereiche, sowie Nachbearbeiten der nachreparierten Bereiche.This object is achieved essentially by the following Process steps solved: First control of the surface quality of the glued plywood after gluing and pre-repairing the Laminated wood, planing the prepared laminated wood onto the desired final dimension, final inspection of the surface quality of the prepared and planed plywood and if necessary Repairs of selected areas, as well as reworking the repaired areas.

Während somit im Falle des bekannten Standes der Technik die Reparatur der Fehlstellen einschließlich der Nachbearbeitung der reparierten Bereiche nach dem Hobeln der Werkstücke erfolgt, wird beim erfindungsgemäßen Verfahren der größte Teil der Fehlstellen vor dem (letzten) Hobeln der Werkstücke repariert und die Nachbearbeitung der reparierten Fehlstellen erfolgt im anschließenden maschinellen Hobelvorgang. Das manuelle Nachbearbeiten dieser reparierten Fehlstellen, welches personalintensiv und daher kostspielig ist, entfällt daher beim erfindungsgemäßen Verfahren. Darüber hinaus kann auf diese Weise im Bereich dieser Fehlstellen eine höhere Oberflächengüte erzielt werden als im Falle des Nacharbeitens von Hand. Auch wird aufgrund des erfindungsgemäßen Verfahrens der Durchsatz erhöht, da das maschinelle Hobeln sehr viel schneller vonstatten geht als das maschinelle Nachbearbeiten. Anschließend an das Hobeln wird erfindungsgemäß die Endkontrolle durchgeführt und es werden dann nur noch die möglicherweise verbleibenden, einige wenigen Fehlstellen von Hand nachrepariert und schließlich von Hand nachgearbeitet.Thus, while in the case of the known prior art Repair of the defects including post-processing of the repaired areas after planing the workpieces is done at inventive method the majority of the defects before (last) planing of the workpieces repaired and the reworking of the repaired defects occur in the subsequent mechanical Planing operation. Manual reworking of these repaired Defects, which are personnel-intensive and therefore expensive, are eliminated therefore in the method according to the invention. In addition, this can Achieved a higher surface quality in the area of these defects be as in the case of reworking by hand. Also due to the The method according to the invention increases the throughput since the machine Planing is much quicker than machine Refinishing. Following planing, the Final inspection carried out and then only the possibly remaining, a few missing parts by hand repaired and finally reworked by hand.

Die Erfindung ermöglicht somit eine gegenüber dem Stand der Technik gesteigerte Oberflächenqualität bei gleichzeitig vermindertem Einsatz an manueller Nachbearbeitung und höherem Durchsatz.The invention thus enables one compared to the prior art increased surface quality with reduced use manual post-processing and higher throughput.

In bevorzugter Weiterbildung der Erfindung ist vorgesehen, daß das Schichtholz zwischen dem Schritt des Verleimens und dem Schritt der ersten Kontrolle einschließlich der Vorreparierens zunächst auf ein Zwischenmaß vorgehobelt wird, welches größer ist als das Endmaß. Hierdurch wird eine saubere und gut bearbeitbare Holzoberfläche erzeugt. Insbesondere dann, wenn die Holzoberflächen, besonders die seitlichen Oberflächen der Bauteile, sehr sauber aus der der Verleimstation nachgeschalteten Presse kommen, kann auf diesen Verfahrensschritt auch verzichtet werden.In a preferred development of the invention it is provided that the Laminated wood between the step of gluing and the step of first check including pre-repair first on a Intermediate dimension is planed, which is larger than the final dimension. This creates a clean and easily editable wooden surface. Especially when the wooden surfaces, especially the side ones Surfaces of the components, very clean from the gluing station downstream press can come to this process step also be dispensed with.

In alternativer Ausgestaltung der Erfindung kann der Schritt der ersten Kontrolle und/oder der Schritt des Vorreparierens maschinell erfolgen; hierzu können geeignete Scanner und entsprechende, über EDV gesteuerte Bearbeitungszentren eingesetzt werden.In an alternative embodiment of the invention, the step of the first Control and / or the preparatory step is carried out mechanically; suitable scanners and corresponding ones can be used for this purpose controlled machining centers are used.

Weitere vorteilhafte Merkmale der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung, in der anhand der Zeichnung ein bevorzugtes Ausführungsbeispiel der Erfindung näher beschrieben wird.

Balkenschichtholz) werden zunächst in der Station 402 auf ein Zwischenmaß vorgehobelt, welches größer ist als das gewünschte Endmaß, so daß die Werkstücke eine saubere und gut bearbeitbare Oberfläche aufweisen.The workpieces glued and pressed in station 400 (Glued laminated timber or laminated timber) are first in the station 402 planed to an intermediate dimension, which is larger than that desired gauge block, so that the workpieces are clean and good have machinable surface.

In der Station 404 erfolgt dann eine erste visuelle Kontrolle der vorgehobelten Werkstücke durch geschultes Personal und eine Reparatur der ermittelten Fehlstellen von Hand unter Einsatz geeigneter Handwerkzeuge und Reparaturmaterialien. Das visuelle Auffinden und manuelle Reparieren erfolgt für jede Fehlstelle von ein und derselben Person. Ein manuelles Nachbearbeiten der reparierten Fehlstellen mittels Schleifen oder Hobeln ist hier nicht erforderlich.A first visual check is then carried out in station 404 Pre-planed workpieces by trained personnel and a repair the identified defects by hand using suitable ones Hand tools and repair materials. The visual finding and manual repairs are carried out for each defect from one and the same Person. A manual reworking of the repaired defects using Grinding or planing is not necessary here.

Die auf diese Weise reparierten Werkstücke werden anschließend in der Station 406 auf das gewünschte Endmaß gehobelt.The workpieces repaired in this way are then in the Plan station 406 to the desired final dimension.

Schließlich werden die reparierten und gehobelten Werkstücke der Station 408 zugeführt, in der dann eine visuelle Endkontrolle der Werkstücke durch geschultes Personal erfolgt und je nach gewünschter bzw. geforderter Oberflächenqualität werden etwa noch vorhandene Fehlstellen von Hand unter Einsatz geeigneter Handwerkzeuge und Reparaturmaterialien repariert.
