Description

Die Erfindung betrifft ein Verfahren zur Vereinzelung plattenförmiger Werkstücke aus Holz oder Holzersatzwerkstoffen.The invention relates to a method for separating panel-shaped workpieces made of wood or wood substitute materials.

Im Zuge der Verarbeitung plattenförmiger Holz- oder Holzersatzwerkstoffe, beispielsweise im Rahmen der Produktion von Möbeln, ist es häufig notwendig, plattenförmige Werkstücke mit gewünschten Maßen zur Weiterverarbeitung bereitzustellen. Diese plattenförmigen Werkstücke werden dabei aus ebenfalls plattenförmigen Halbzeugen herausgetrennt und dadurch vereinzelt.In the course of processing board-shaped wood or wood substitute materials, for example in the production of furniture, it is often necessary to provide board-shaped workpieces with the desired dimensions for further processing. These plate-shaped workpieces are separated from semi-finished products that are also plate-shaped and thereby isolated.

Dabei erfolgt das Heraustrennen der Werkstücke aus den Halbzeugen nach vorgegebenen Schnittmustern. Diese werden regelmäßig so gewählt, dass der Verschnitt gering ist, d.h. dass eine möglichst große Gesamtfläche weiter verarbeitbarer Werkstoffe aus einem plattenförmigen Halbzeug gewonnen wird. Aus DE 10 2009 033 813 A1 ist ein Verfahren nach dem Oberbegriff des Anspruchs 1 bekannt. Dort wird eine großformatige Platte zunächst formatiert, indem ein stufiger Rückschnitt über die gesamte Breite der Platte durchgeführt wird. Anschließend wird dieses gestufte Format über einen Trennschnitt abgetrennt. Danach werden Schnitte durchgeführt, die einzelne Teile aus diesem Format vereinzeln. Dieses Procedere wird wiederholt.The workpieces are separated from the semi-finished products according to specified cutting patterns. These are regularly selected in such a way that the waste is low, ie that the largest possible total area of further processable materials is obtained from a plate-shaped semi-finished product. the end DE 10 2009 033 813 A1 a method according to the preamble of claim 1 is known. There, a large-format panel is first formatted by cutting back in stages across the entire width of the panel. This graded format is then separated using a separating cut. Then cuts are made that separate individual parts from this format. This procedure is repeated.

Dabei ist das Heraustrennen der einzelnen plattenförmigen Werkstücke aus dem Halbzeug jedoch zeitaufwendig, da das Bearbeitungsaggregat, mit dem die Werkstücke aus dem Halbzeug herausgetrennt werden, oft komplizierte Verfahrwege zurücklegen muss.However, cutting out the individual plate-shaped workpieces from the semi-finished product is time-consuming, since the processing unit with which the workpieces are cut out from the semi-finished product often has to cover complicated travel paths.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Vereinzelung plattenförmiger Werkstücke aus Holz oder Holzersatzwerkstoffen anzugeben, welches mit kürzeren Bearbeitungszeiten durchgeführt werden kann.The invention is therefore based on the object of specifying a method for separating panel-shaped workpieces made of wood or wood substitute materials, which can be carried out with shorter processing times.

Die Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen des Anspruchs 1. Die Merkmale der abhängigen Ansprüche betreffen vorteilhafte Ausführungsformen. Erfindungsgemäß wird zunächst eine Mehrzahl Schnitte vorzugsweise ausgehend von der Randkontur des Halbzeugs vorgenommen. Während der Vornahme dieser Schnitte bleiben die einzelnen Bereiche des Halbzeugs, welche später die einzelnen Werkstücke bilden, ein zusammenhängendes Gebilde. Die Vereinzelung der Werkstücke erfolgt dann durch einen weiteren, die einzelnen Schnitte verbindenden Schnitt. Dieser Schnitt verläuft vorzugsweise durch die Endpunkte und/oder Endbereiche der zuvor vorgenommenen Schnitte, so dass sich ein kammartiges Schnittmuster ergibt. Dabei führt das Erreichen eines der zuvor vorgenommenen Schnitte durch den weiteren Schnitt zur Vereinzelung eines Werkstücks, d.h. zur vollständigen Abtrennng eines das Werkstück bildenden Bereichs von dem restlichen Halbzeug.The object is achieved by a method having the features of claim 1. The features of the dependent claims relate to advantageous embodiments. According to the invention, a plurality of cuts is first made, preferably starting from the edge contour of the semi-finished product. While these cuts are being made, the individual areas of the semi-finished product, which will later form the individual workpieces, remain a coherent structure. The workpieces are then separated by a further cut that connects the individual cuts. This cut preferably runs through the end points and/or end areas of the previously made cuts, resulting in a comb-like cutting pattern. The achievement of one of the previously made cuts by the further cut leads to the separation of a workpiece, i.e. to the complete separation of an area forming the workpiece from the remaining semi-finished product.

Dabei ist es vorteilhaft, wenn der weitere Schnitt zur Vereinzelung der Werkstücke entlang einer Linie erfolgt, die vorzugsweise so im Halbzeug orientiert ist, dass die Linie quer zur Förderrichtung des Halbzeugs bei dessen Verarbeitung verläuft.It is advantageous if the further cut for separating the workpieces is made along a line which is preferably oriented in the semi-finished product in such a way that the line runs transversely to the conveying direction of the semi-finished product during its processing.

Die Linie weist erfindungsgemäß einen gestuften Verlauf auf. Auf diese Weise entsteht eine Art Streifen aus Werkstücken, die mit einem gemeinsamen weiteren Schnitt vereinzelt werden. Nach der Vereinzelung eines solchen Streifens aus Halbzeugen können dann vorzugsweise weitere Streifen an Werkstücken durch eine Wiederholung des oben beschriebenen Vereinzelungsverfahrens erzeugt werden. Dabei zeichnet sich das Schnittmuster vorzugsweise im Wesentlichen dadurch aus, dass die streifenförmig angeordneten Halbzeuge entgegen der Durchlaufrichtung des Halbzeugs bei der Verarbeitung an eine gemeinsame Schnittlinie grenzen. Die in die Förderrichtung weisenden Wandkonturen der zu vereinzelnden Werkstücke können dagegen unterschiedlichste Geometrien aufweisen. In diesem Zusammenhang ist es vorteilhaft, wenn zunächst die Randkontur des in die Bearbeitung nach dem erfindungsgemäßen Verfahren einlaufenden Halbzeugs bearbeitet wird und zwar insbesondere an der in Förder- bzw. Durchlaufrichtung weisenden Randkontur. Ausgehend von der so erzeugten Randkontur werden dann nach dem erfindungsgemäßen Verfahren zunächst eine Mehrzahl Schnitte vorgenommen, welche dann durch den weiteren Schnitt zur Vereinzelung der einzelnen Werkstücke verbunden werden.According to the invention, the line has a stepped profile. In this way, a kind of strip of workpieces is created, which are separated with a further joint cut. After the separation of such a strip of semi-finished products, further strips of workpieces can then preferably be obtained by repeating the above separation method described are generated. In this case, the cutting pattern is preferably essentially characterized in that the semi-finished products arranged in a strip-like manner adjoin a common cutting line counter to the through-feed direction of the semi-finished product during processing. In contrast, the wall contours of the workpieces to be separated, pointing in the conveying direction, can have the most varied of geometries. In this context, it is advantageous if the edge contour of the semi-finished product entering the processing according to the method according to the invention is processed first, in particular on the edge contour pointing in the conveying or throughput direction. Starting from the edge contour produced in this way, a plurality of cuts are then initially made according to the method according to the invention, which are then connected by the further cut for separating the individual workpieces.

Dabei ist es vorteilhaft, wenn die einzelnen Werkstücke während des Durchführens der Schnitte, insbesondere während der Durchführung des weiteren Schnitts zur Vereinzelung der Werkstücke durch eine Fixiereinrichtung gehalten werden. Die Fixierung vorteilhafterweise des Werkstücks und/oder dem verbleibenden Halbzeug, insbesondere im Moment seiner vollständigen Abtrennung von dem verbleibenden Halbzeug, wirkt sich positiv auf eine saubere Ausführung der Schnitte aus, da bis zum vollständigen Abschluss des Schnittvorgangs die Position, insbesondere beider zu trennenden Plattenbereiche, sichergestellt ist.It is advantageous if the individual workpieces are held by a fixing device while the cuts are being made, in particular while the further cut is being made to separate the workpieces. The fixation advantageously of the workpiece and/or the remaining semi-finished product, in particular at the moment of its complete separation from the remaining semi-finished product, has a positive effect on a clean execution of the cuts, since until the complete completion of the cutting process the position, in particular of both plate areas to be separated, is ensured.

Dabei kann es von Vorteil sein, wenn die Fixiereinrichtung so ausgebildet ist, dass sie in der Lage ist, sämtliche Werkstücke eines Streifens des Schnittmusters gleichzeitig zu fixieren. Alternativ oder ergänzend können auch eine Mehrzahl Fixiereinrichtungen vorhanden sein, die das Fixieren einzelner Werkstücke eines Streifens durch jeweils den einzelnen Werkstücken zugeordnete Fixiereinrichtungen ermöglichen.It can be advantageous if the fixing device is designed in such a way that it is able to fix all the workpieces of a strip of the cutting pattern at the same time. Alternatively or additionally, a plurality of fixing devices can also be present be, which allow the fixing of individual workpieces of a strip by fixing devices assigned to the individual workpieces.

Vorteilhafterweise erfolgen Schnitte durch Fräsen. Die Fräsbearbeitung hat den Vorteil, dass nahezu beliebige Schnittgeometrien bzw. Schnittmuster realisiert werden können. Insbesondere lässt sich die Schnittrichtung eines Fräsers während der Durchführung des Schnittes abrupt ändern.Cuts are advantageously made by milling. Milling has the advantage that almost any cutting geometry or cutting pattern can be realized. In particular, the cutting direction of a milling cutter can be changed abruptly while the cut is being made.

Die Erfindung wird im Folgenden anhand der Figuren 1 bis 6 schematisch näher erläutert.

  • Fig. 1 zeigt ein bespielhaftes erfindungsgemäßes Schnittmuster mit einer streifenfömigen Anordnung der Werkstücke.
  • Fig. 2 und 3 zeigen das Halbzeug aus Fig. 1 in verschiedenen Stadien der Durchführung des erfindungsgemäßen Verfahrens während im Halbzeug endende Schnitte mit gleichzeitiger Bearbeitung der Randkontur in Förderrichtung vorgenommen werden.
  • Fig. 4 zeigt das Halbzeug aus Fig. 1 nach erfolgter Bearbeitung der Randkontur.
The invention is based on the Figures 1 to 6 schematically explained in more detail.
  • 1 shows an exemplary cutting pattern according to the invention with a strip-like arrangement of the workpieces.
  • 2 and 3 show the semi-finished product 1 in various stages of implementation of the method according to the invention while ending cuts are made in the semi-finished product with simultaneous processing of the edge contour in the conveying direction.
  • 4 shows the semi-finished product 1 after the edge contour has been processed.

Die Fig. 5 und 6 zeigen das Halbzeug aus Fig. 1 unmittelbar vor und nach der Durchführung des weiteren Schnitts zur Vereinzelung der Werkstücke nach dem erfindungsgemäßen Verfahren.the figure 5 and 6 show the semi-finished product 1 immediately before and after the implementation of the further cut for separating the workpieces according to the method according to the invention.

Vorteilhafterweise läuft zunächst ein plattenförmiges Halbzeug 1 in einer Förderrichtung X in den Bereich der zur Durchführung des Verfahrens verwendeten und nicht dargestellten Bearbeitungseinrichtung ein. Das erfindungsgemäße Verfahren kann nun beispielsweise in einer Reihenfolge der Bearbeitungsschritte durchgeführt werden, die sich aus den Fig. 1, 2, 3, 5 und 6 ergibt. In diesem Fall wird zunächst mit einem geeigneten Bearbeitungsaggregat, beispielsweise einem Fräser, eine Mehrzahl Schnitte 4 vorgenommen, die im gezeigten Beispiel ausgegehend von der, vorzugsweise in Förderrichtung X weisenden, Randkontur 6 in das plattenförmige Halbzeug 1, vorzugsweise entgegen der Förderrichtung X, hineinlaufen und in der, vorzugsweise quer zur Förderrichtung X verlaufenden, Richtung Y die einzelnen Werkstücke 2.1 bis 2.7 voneinander separieren. Während der Durchführung dieser Prozessschritte bleiben die Werkstücke 2.1 bis 2.7 mit dem verbleibenden Halbzeug 3 verbunden. Abhängig von der genauen Gestaltung des Schnittplans ist es dabei möglich, Werkstücke - wie im gezeigten Beispiel die Werkstücke 2.8 und 2.9 - vorzusehen, die zwischen der Randkontur des Halbzeugs und dem eigentlichen aus den Werkstücken 2.1 bis 2.7 gebildeten Streifen angeordnet sind. Diese Werkstücke 2.8 und 2.9, bei denen es sich auch um Verschnittstücke handeln kann, werden zwischen der Durchführung einzelner im Halbzeug 1 endender Schnitte 4 durch entsprechend winklig geführte Schnitte 5 vereinzelt.Advantageously, first a plate-shaped semi-finished product 1 runs in a conveying direction X in the area used for carrying out the method and not shown processing device. The inventive method can now be carried out, for example, in a sequence of processing steps resulting from the 1 , 2 , 3 , 5 and 6 results. In this case, first a plurality of cuts 4 are made with a suitable processing unit, for example a milling cutter separate the individual workpieces 2.1 to 2.7 from one another in the direction Y, which preferably runs transversely to the conveying direction X. While these process steps are being carried out, the workpieces 2.1 to 2.7 remain connected to the remaining semi-finished product 3. Depending on the exact design of the cutting plan, it is possible to provide workpieces - such as workpieces 2.8 and 2.9 in the example shown - which are arranged between the edge contour of the semi-finished product and the actual strip formed from workpieces 2.1 to 2.7. These workpieces 2.8 and 2.9, which can also be offcuts, are separated between the execution of individual cuts 4 ending in the semifinished product 1 by cuts 5 made at an appropriate angle.

Nach der Durchführung der im Halbzeug endenden Schnitte weist das Halbzeug 1 die in Fig. 5 dargestellte Geometrie auf. Um die in Fig. 6 dargestellte Vereinzelung der den Streifen 7 bildenden Werkstücke 2.1 bis 2.7 zu erreichen, wird ein weiterer Schnitt 8, welcher die im Halbzeug endenden Schnitte miteinander verbindet, durchgeführt. Durch den Schnitt 8 werden die Werkstücke 2.1 bis 2.7 vereinzelt. Der verbleibende Bereich des Halbzeugs 3 kann nun analog zu dem die Werkstücke 2.1 bis 2.9 beinhaltenden Schnittmuster nach einem weiteren vorzugsweise ebenfalls streifenförmigen Schnittmuster bearbeitet werden, vorzugsweise bis das halbzeug 1 vollständig zu Werkstücken verarbeitet worden ist.After making the cuts ending in the semi-finished product, the semi-finished product 1 has the in figure 5 geometry shown. To the in 6 To achieve the illustrated separation of the workpieces 2.1 to 2.7 forming the strip 7, a further cut 8, which connects the cuts ending in the semi-finished product with one another, is carried out. The workpieces 2.1 to 2.7 are separated by the cut 8 . The remaining area of the semi-finished product 3 can now preferably also be cut analogously to the cutting pattern containing the workpieces 2.1 to 2.9 strip-shaped patterns are processed, preferably until the semi-finished product 1 has been completely processed into workpieces.

Im Hinblick auf die Reihenfolge der einzelnen Bearbeitungsschritte ist es ebenfalls möglich und insbesondere bei der Verwendung mehrerer Aggregate zur Durchführung der Schnitte, insbesondere mehrerer Frässpindeln, auch vorteilhaft, wenn die Vereinzelung der Werkstücke 2.1 bis 2.9 nach dem in er Sequenz der Fig. 1, 4, 5 und 6 dargestellten beispielhaften erfindungsgemäßen Verfahren erfolgt. Dies sieht vor, dass zunächst die Bearbeitung der in Förderrichtung X weisenden Randkontur 6 des Halbzeugs 1 erfolgt. Dies beinhaltet insbesondere die Entfernung von Verschnittstücken bzw. zwischen Randkontur und dem eigentlichen Streifen 7 der Werkstücke 2.1 bis 2.7 beispielhaft dargestellter Werkstücke 2.8 und 2.9.With regard to the order of the individual processing steps, it is also possible and particularly advantageous when using multiple units to carry out the cuts, in particular multiple milling spindles, if the separation of the workpieces 2.1 to 2.9 after the sequence in it 1 , 4 , 5 and 6 illustrated exemplary method according to the invention takes place. This provides that the edge contour 6 of the semi-finished product 1 pointing in the conveying direction X is first machined. This includes in particular the removal of offcuts or between the edge contour and the actual strip 7 of the workpieces 2.1 to 2.7 of workpieces 2.8 and 2.9 shown as examples.

Ist die Randkontur 6 in Förderrichtung X soweit bearbeitet wie es in fig. 4 dargestellt ist, nämlich so, dass ausgehend von der für den Schnit 8 vorgesehenen Schnittlinie in Förderrichtung X sich an jeder Stelle des halbzeugs 1 nur noch ein Werkstück 2.1 bis 2.7 an den verbleibenden Bereich 3 des Halbzeugs 1 anschließt, so können nun die im Halbzeug endenden Schnitte 4 vorgenommen werden, um zu der in Fig. 5 dargestellten Geometrie zu gelangen. Dabei können vorteilhafterweise, wenn eine Mehrzahl Bearbeitungsaggregate zur simultanen Bearbeitung zur Verfügung steht, eine Mehrzahl Schnitte 4 gleichzeitig durchgeführt werden. Dadurch ist diese Variante der Verfahrensführung beispielsweise bei mehrspindeligen Fräsmaschinen, die zur Durchführung des Verfahrens verwendet werden, vorteilhaft.If the edge contour 6 is processed in the conveying direction X as far as it is in figure 4 is shown, namely in such a way that, starting from the cutting line provided for the cut 8 in the conveying direction X, only one workpiece 2.1 to 2.7 adjoins the remaining area 3 of the semi-finished product 1 at each point of the semi-finished product 1, so the ones ending in the semi-finished product can now Cuts 4 are made in order to figure 5 geometry shown. Advantageously, if a number of processing units are available for simultaneous processing, a number of cuts 4 can be carried out simultaneously. As a result, this variant of the procedure is advantageous, for example, in the case of multi-spindle milling machines that are used to carry out the procedure.

Die Vereinzelung der Werkstücke 2.1 bis 2.7 erfolgt dann auch bei dieser Variante des Verfahrens wie in den Fig. 5 und 6 dargestellt und oben beschrieben.The workpieces 2.1 to 2.7 are then also separated in this variant of the method as in FIGS figure 5 and 6 shown and described above.
