Description

Die Erfindung betrifft eine Keilzinkenfräse zur Herstellung von Keilzinken an der Stirnseite von Brettern, die mit mit entsprechenden Keilzinken versehenen Brettern stirnseitig in fortlaufender Folge oder einzeln verleimt werden sollen.The invention relates to a finger joint milling machine for the production of finger joints on the end face of boards which are to be glued on the end face in continuous succession or individually with boards provided with corresponding finger joints.

Bei herkömmlichen Verfahren zur Herstellung von Keilverzinkungen werden Bretter unterschiedlicher Länge hochkant stehend auf einen Frästisch zu Stapeln unter Ausrichten an einer ihrer Stirnseiten zusammengefaßt und dort mit einem Zerspahner oder einer Kreissäge im rechte Winkel zu den Brettersäumen geradegeschnitten. Sodann werden die 10 bis 30 cm langen Keilzinken von einem Profilfräser herausgeschnitten und anschließend mit Leim angegeben. Die Bretter werden im nächsten Schritt an ihren anderen Stirnseiten aufeinander ausgerichtet und von einem zweiten Satz der gleichen Maschinen mit Keilzinken versehen, die mit Leim angegeben werden. Die so bearbeiteten Bretter werden anschließend mit ihren Zinkenprofilen zusammengefügt und während des Abbindens des Leims in einer Keilzinkenpresse verpreßt.In conventional methods for the production of finger joints, boards of different lengths are stacked upright on a milling table and aligned on one of their end faces, where they are cut straight at right angles to the board edges using a cutter or a circular saw. Then the 10 to 30 cm long finger tines are cut out by a profile cutter and then given with glue. In the next step, the boards are aligned with each other on their other faces and are finger-jointed by a second set of the same machines, which are given with glue. The so processed boards are then joined together with their tine profiles and pressed in a finger press during the setting of the glue.

Bei der so gegebenen Notwendigkeit der Verwendung zweier Profil-fräsen für die beiden Bretterenden muß die Geometrie der beiderseitigen Werkzeuge genau aufeinander verpaßt sein, um beim Zusammensetzen der Bretter zu Bahnen einen völlig exakten Fugenverlauf zu erhalten und Verbindungslücken oder Verquetschungen zu vermeiden, vorallem aber um eine Verleimung der Zinken auf ihre gesamte Länge sicherzustellen. Die Verbindung der Bretter muß so sein, daß sie in ihrer statischen Belastbarkeit der von gewachsenem Holz entspricht. Es entstehen also Anpassungsprobleme beim Nachschleifen der Werkzeuge, was zu zeitraubenden Produktionsunterbrechungen führt. Auch erfordert der doppelte Satz von Bearbeitungsmaschinen erheblichen Stellraum. Es wurde vorgeschlagen, den Fräßtisch für die 5 m und mehr langen Bretter einen um 180° schwenkbaren Frästisch anzuordnen, um mit nur einem Satz der Bearbeitungsmaschinen auszukommen, da dann beide Enden des Bretterstapels an der selben Stelle zugerichtet werden können, doch dann ergibt sich ein noch größerer Platzbedarf und eine Verminderung der Leistung je Zeiteinheit.Given the need to use two profile milling cutters for the two board ends, the geometry of the tools on both sides must be precisely matched to one another in order to obtain a completely exact joint course when assembling the boards into strips and to avoid connection gaps or crushing, but above all by one Ensure that the tines are glued along their entire length. The connection of the boards must be such that their static load capacity corresponds to that of grown wood. So there are adjustment problems when regrinding the tools, which leads to time-consuming production interruptions. The double set of processing machines also requires considerable space. It has been proposed to arrange the milling table for the 5 m and more long boards with a milling table which can be swiveled through 180 ° in order to get by with only one set of the processing machines, since both ends of the board stack can then be trimmed in the same place, but this results in even larger space requirements and a reduction in performance per unit of time.

Aufgabe der Erfindung war es, Platzbedarf und Kostenaufwand für eine Keilzinkenfräsanlage wesentlich zu verringern und andererseits ihre Leistung zu erhöhen wie auch ihre Bedienung zu vereinfachen.The object of the invention was to significantly reduce the space and cost of a finger jointing system and, on the other hand, to increase its performance and to simplify its operation.

Diese Aufgabe wird mit den in den Ansprüchen angegebenen Maßnahmen gelöst.This object is achieved with the measures specified in the claims.

Die Erfindung ermöglicht eine erhebliche Verbesserung und wirkungsvolle Beschleunigung der Bearbeitung der für Schichtholzträger bestimmten Bretter. Die automatisch zuführbaren Bretter werden in einem programmierbaren Arbeitsgang beiderseits gefräst und eingeleimt. Sie können dann wieder automatisch zur Keilzinkenpresse transportiert werden. Handarbeit, insbesondere das Herumheben der Bretter ist vermiedenThe invention enables a considerable improvement and effective acceleration of the processing of the boards intended for plywood beams. The automatically feedable boards are milled and glued on both sides in one programmable operation. They can then be automatically transported to the finger press again. Manual work, in particular lifting the boards around is avoided

Die in Figur 1 dargestellte Keilzinkenfräse weist zwei gegeneinander in Richtung der Pfeile 1 und 2 verschiebbaren Tishe 3 und 4 auf, über die die zu bearbeitenden, hochkant liegendenden und zu einem Stapel geordneten Bretter 5 geschoben und durch einen Anschlag 6 zur Bearbeitung ausgerichtet werden. In Richtung der Pfeile 7 und 8 ist die Fräsvorrichtung 9 vor den Stirnseiten der Bretter 5 durch nicht dargestellte Arbeitszylinder verschiebbar. Die Fräsvorrichtung 9 besteht aus einem Zerspaner 10 zum Geradeschneiden der Enden der Bretter 5 in der Ebene der gestrichelten Linie 11, der ein Keilzinkenprofil aufweisenden Fräse 12 zum Schneiden der Keilzinken und der Leimangabevorrichtung 13, mit der die geschnittenen Keilzinken mit Leim versehen werden. Zerspaner 11, Fräse 12 und Leimangabevorrichtung 13 sind auf einer gemeinsamen nicht dargestellten Konsole angeordnet. Die Fräsvorrichtung 9 ist um die senkrechte Achse 14 der Fräse 14 um 180° auf dieser Konsole schwenkbar.The finger jointing machine shown in FIG. 1 has two tables 3 and 4 which can be displaced relative to one another in the direction of arrows 1 and 2, over which the boards 5 to be machined, lying upright and arranged in a stack, are pushed and aligned by a stop 6 for processing. In the direction of arrows 7 and 8, the milling device 9 can be displaced in front of the end faces of the boards 5 by working cylinders, not shown. The milling device 9 consists of a chipper 10 for cutting the ends of the boards 5 in the plane of the dashed line 11, the milling cutter 12 having a finger joint profile for cutting the finger joints and the glue dispensing device 13 with which the cut finger joints are provided with glue. Chipper 11, milling machine 12 and glue dispenser 13 are arranged on a common console, not shown. The milling device 9 can be pivoted about the vertical axis 14 of the milling cutter 14 by 180 ° on this console.

Die Wirkungsweise ist folgende: Die Bretter 5, die verschiedene Längen aufweisen, werden auf den Tisch 3 bei dessen Zurückfahren in Richtung des Pfeiles 2 aufgeschoben und bei dessen Wiedervorfahren in Richtung des Pfeiles 1 an dem dann in die Lage der gestrichelten Linie 11 versetzten Anschlag 6 ausgerichtet, sodaß ihre Stirnseiten in der Ebene des Zerspaners 10 liegen Die Fräsvorrichtung 9 fährt dann in Richtung des Pfeiles 7 durch, schneidet die Enden der Bretter 5 glatt, fräst die Keilzinken und versieht sie mit Leim, wie dies in Figur 2 a dargestellt ist. Die Fräsvorrichtung 9 fährt bis zur Position 15 durch und schwenkt dort um die Achse 14 der Fräse 12 um 180°. Gleichzeitig fahren die Tische 3 und 4 aufeinander zu, wobei der Tisch 4 den Stapel der Bretter 5 beim erneuten Auseinanderfahren der Tische 3 und 4 in Richtung der Pfeile 1 und 2 übernimmt. Nach Versetzen des Anschlages 6 in die in Figur 1 gezeigte Stellung werden die Bretter 5 bei Wiederzurückfahren des Tisches 4 in Richtung des Pfeiles 2 an ihrem anderen Ende auf die gestrichelte Linie 11 ausgerichtet und in der Richtung des Pfeiles 8 glattgeschnitten, auf Keilzinken gefräst und mit Leim versehen, wie dies Figur 2 b zeigt. In ihrer Endposition wird die Keilzinkenfräse 9 wieder um 180° in ihre ursprüngliche Stellung zurückgeschwenkt, um den nächsten ankommenden Bretterstapel zu beschneiden.The mode of operation is as follows: The boards 5, which have different lengths, are pushed onto the table 3 when it moves back in the direction of arrow 2 and when it moves forward in the direction of arrow 1 at the stop 6 which is then moved into the position of the broken line 11 aligned so that their end faces are in the plane of the chipper 10. The milling device 9 then moves in the direction of Arrow 7 through, cuts the ends of the boards 5 smooth, milled the finger joints and provides them with glue, as shown in Figure 2a. The milling device 9 travels to position 15 and pivots there about the axis 14 of the milling cutter 12 by 180 °. At the same time, the tables 3 and 4 move towards one another, the table 4 taking over the stack of boards 5 when the tables 3 and 4 move apart again in the direction of the arrows 1 and 2. After moving the stop 6 into the position shown in Figure 1, the boards 5 are aligned when the table 4 is moved back in the direction of arrow 2 at its other end to the dashed line 11 and cut smooth in the direction of arrow 8, milled on finger joints and with Apply glue, as shown in Figure 2 b. In its end position, the finger jointing machine 9 is pivoted back into its original position by 180 ° in order to trim the next stack of boards arriving.

Die verschiedenlangen Bretter 5 sind dann an beiden Enden mit geometrisch genau gleichen und beleimten Keilverzinkungen versehen und können nun einzeln hintereinander in die Keilzinkenpresse befördert und dort zu einem endlosen Band zusammengesetzt werden.The boards 5 of different lengths are then provided at both ends with geometrically exactly the same and glued finger joints and can now be conveyed one after the other into the finger press and assembled there to form an endless belt.

Bei der Ausführungsform zu Figur 3 sind die Tische 16 und 17 um die senkrechten Achsen 18 und 19 in horizontaler Ebene schwenkbar, sodaß Schrägschnitte möglich sind. Die Anordnung der Keilzinkenfräse 20 ist die gleiche wie die bei der in Figur 1 gezeigte Es ist jedoch statt des Zerspaners 10 eine Kreissäge 10' vorgesehen, da hier die Bretter in einem Winkel, wie er bei 20 gezeigt ist, durchgeschnitten und nicht nur abgerichtet werden müssen.In the embodiment of Figure 3, the tables 16 and 17 are pivotable about the vertical axes 18 and 19 in the horizontal plane, so that bevel cuts are possible. The arrangement of the finger jointing machine 20 is the same as that shown in FIG. 1 However, instead of the chipper 10, a circular saw 10 'is provided, since here the boards have to be cut through at an angle, as shown at 20, and not just dressed.

Die Keilzinkenfräse kehrt hier in gleicher Weise, wenn sie die Bretter an einer Stirnseite beschnittewn hat, nach Schwenken um 180° um, um die anderen Enden der Bretter 5 zu bearbeiten, und sie schwenkt nach Erreichen ihrer Ausgangsposition wieder um 180° zurückThe finger joint milling machine turns here in the same way, if it has trimmed the boards on one end side, after swiveling through 180 ° in order to machine the other ends of the boards 5, and swivels back again after reaching its starting position by 180 °

In Figur 4 sind Holzkonstruktionen aus Schichtholzträgerteilen dargestellt, die sich mit Brettern herstellen lassen, die mit der Anardnung gemäß Figur 3 zugeschnitten und mit Keilverzinkungen versehen sind.FIG. 4 shows wooden structures made of plywood support parts that can be produced with boards that are cut to size according to FIG. 3 and are provided with finger joints.

Bei den gezeigten Ausführungsformen können alle Bewegungen der Tische 3, 4 , 16 und 17 sowie die der Keilzinkenfräsen 9 und 20 bzw. die ihrer Konsolen mit Hilfe von Arbeitszylinder ausgeführt werden, wobei die gesamte hydraulische Anlage auf den beschriebenen Arbeitsgang programmiert sein kann, sodaß Handarbeit im laufenden Arbeitsgang vollständig vermieden wird.In the embodiments shown, all movements of the tables 3, 4, 16 and 17 as well as those of the finger jointing machines 9 and 20 or that of their consoles can be carried out with the aid of working cylinders, whereby the entire hydraulic system can be programmed for the work step described, so that manual work is completely avoided in the current operation.
