Abstract
Description
Bei Leisten Brettern, Bohlen, Balken und ähnlichen Werkstücken, besteht sehr häufig Bedarf an langen Einheiten, die aus Vollholz nur schwer zu schneiden sind. Man hat zur Gewinnung langer Einheiten, insbes. bei Rundholz, mit grossem Aufwand, die Holzteile mit langen diagonalen Schnitten geschäftet um ausreichend grosse Verbindungsflächen für die Verleimung der Teile zu bekommen. Eine andere bekannte und bewährte Methode zur stirnseitigen Verbindung von Werkstücken, ist das Einfräsen von keilförmigen Zinken in deren Stirnflächen, die unter Einsatz von Klebstoffen und Druck miteinander verbunden werden. Mit dieser Methode werden Verbindungen für beliebig lange Werkstücke erreicht, die in etwa den Eigenschaften von Vollholz entsprechen.For strips, planks, beams and the like Workpieces, exists very often Need for long units that are difficult to cut from solid wood are. You have to get long units, especially with logs, with great effort, the wooden parts with long diagonal cuts scarfed for sufficiently large connecting surfaces for gluing the parts to get. Another known and proven method for frontal Connection of workpieces, is milling in wedge-shaped Tines in their end faces, which are bonded together using adhesives and pressure become. With this method, connections for workpieces of any length are achieved, which roughly correspond to the properties of solid wood.
Nach dem Einfräsen der Keilzinken in die Stirnseiten der Werkstücke, wird in die gefrästen Stirnseiten Klebstoff eingebracht und diese dann unter Druck so ineinander geschoben, dass allein diese Druckverbindung ausreichend fest ist, die verbundenen Werkstücke problemlos weiter in den Bereich einer Einrichtung zu bewegen, in der die Werkstücke auf die gewünschte Länge geschnitten werden.After the finger joints have been milled into the end faces the workpieces, is in the milled end faces Glue introduced and then pushed together under pressure so that this pressure connection alone is sufficiently firm, the connected ones workpieces move easily into the area of a facility, in of the workpieces the desired Cut length become.
Für das Bewegen, Ausrichten und Einspannen der Werkstücke auf einem Presstisch zur Vorbereitung des nachfolgenden Fräs-Arbeitsganges, ergeben sich ebenso wie bei den Folgearbeiten, vom Zusammenpressen der Werkstücke bis zum Transport, dadurch unerwünschte Standzeiten und damit Verlustzeiten, weil die nachfolgenden Werkstücke erst nach der Rückführung der Fräseinrichtung in die Ausgangsstellung, ausgerichtet und eingespannt werden können.For moving, aligning and clamping the workpieces a press table to prepare the subsequent milling operation, result from the pressing together, just as with the follow-up work of the workpieces until transportation, thereby undesirable Downtimes and thus lost times, because the subsequent workpieces first after the return of the milling device in the starting position, can be aligned and clamped.
Bei diesen Anlagen ist also die Richtarbeit für das Einspannen und Fixieren der Werkstücke erst freigegeben, wenn die Fräseinrichtung für den folgenden Arbeitsgang in die Ausgangsposition zurückgeführt ist. Üblicher Weise steht das Fräsaggregat nach der Bearbeitung der Stirnflächen der Werkstücke oberhalb des Arbeitsplatzes an dem die Werkstücke bearbeitet und gepresst wurden, also oberhalb der Auflageflächen der Presstische. Dieser Arbeitsbereich wird für das Ausrichten und Einspannen der Werkstücke benötigt, kann aber nicht genutzt werden, weil vorher das Fräsaggregat aus dieser Position in die unterhalb der Presstischebene liegende Ausgangsposition gebracht werden muss. Das kann nur geschehen, wenn die unter Druck ineinander geschobenen Werkstücke den Arbeitsbereich des Fräsers verlassen haben und das nachfolgende Werkstück noch nicht bis zur Bearbeitungsstelle nachgeschoben ist. Hier ergeben sich von einem Arbeitsbereich zum nächsten Verlustzeiten.With these systems, therefore, is the leveling work for the Clamping and fixing the workpieces only released when the milling device for the following operation is returned to the starting position. usual The milling unit is inferior the machining of the end faces of the workpieces above the workplace where the workpieces are machined and pressed above the contact surfaces of the press tables. This Workspace is for alignment and clamping of the workpieces is required, but cannot be used because the milling unit from this position to the starting position below the press table level must be brought. That can only happen when under pressure nested workpieces the working area of the router have not left the following workpiece and have not yet reached the machining point is pushed. Here arise from one work area to the next Lost time.
Ein anderes bekanntes Verfahren teilt den Arbeitszyklus in drei Arbeitsprozesse die in parallel arbeitende Arbeitsstationen aufgeteilt werden können, so dass unter Einschaltung von Zwischenlagern ohne Verlustzeiten durchgearbeitet werden kann. Bei diesem Verfahren wird zumindest das Fräsen und das Zusammenpressen auf getrennten Arbeitsplätzen durchgeführt, was hinsichtlich des Aufwandes an Raum, Transportbewegungen und vor allem wegen der geringeren Passgenauigkeit der gefrästen Zinken unerwünscht istAnother known method shares the work cycle in three work processes that in parallel Workstations can be divided, so that with activation can be worked through from interim storage facilities without loss of time. In this process, at least the milling and pressing together in separate workplaces carried out, what about the amount of space, transport movements and especially undesirable because of the less precise fit of the milled tines
Der Erfindung liegt die Aufgabe zugrunde, unter Beibehaltung einer hohen Qualität, mit einer einstufigen Bearbeitungsstelle zu arbeiten, bei der die durch die Folgearbeiten an den bewegten Werkstücken sich ergebenden Zeitverluste vermindert, die Leistung also gesteigert ist.The invention is based, below Maintaining high quality, to work with a one-step processing center, where the time losses resulting from the subsequent work on the moving workpieces reduced, so the performance is increased.
Gemäss der Erfindung wird dies durch eine Anlage zum stirnseitigen Verbinden von Werkstücken aus Holz oder ähnlichem Material unter Verwendung von Klebstoff erreicht, bei der die auf einem Presstisch eingespannten Werkstücke an den zu verbindenden Stirnseiten von einem Fräsaggregat so bearbeitet werden, dass kongruent ineinander passende Zinken entstehen, die unter Einsatz von Druck ineinander greifend eine stabile Verbindung ergeben.According to the invention, this is through a system for the frontal connection of workpieces Wood or the like Material achieved using glue at which the on a press table clamped workpieces on the to be connected End faces of a milling unit are machined in such a way that the tines fit together arise that interlock using pressure result in stable connection.
Gemäss der Erfindung wird diese Aufgabe durch die im Kennzeichen des Anspruches eins angegebenen Mittel und Einrichtungen erreicht.According to the invention, this is Task by the specified in the characterizing part of claim one Funds and facilities reached.
An Hand der Zeichnungen wird eine Anlage gemäss der Erfindung beschrieben und deren Wirkungsweise erläutert.Based on the drawings, a Plant according to described the invention and its operation explained.

Mit der Anlage nach der Erfindung wird erreicht, dass der aus drei Arbeitsgängen bestehende Arbeitsprozess zur Verbindung von Stirnflächen an Brettern oder dgl., nämlich das Profilieren der Stirnflächen, das Auftragen von Klebstoff und das Zusammenfügen der Werkstücke in einem durchlaufenden Arbeitsgang ohne Zusatzzeiten, mit hoher Passgenauigkeit erfolgt. Diese damit verbundene Zeitersparnis ist möglich, weil das Richten, das Fräsen und das Zusammenfügen eines Werkstückes auf dem gleichen Presstisch und mit den genau ausgerichteten, synchron laufenden Fräsköpfen, gleichzeitig oder zumindest zeitlich überlappend erfolgt, also Verlustzeiten vermeidet.With the system according to the invention is achieved that the work process consisting of three work steps for connecting end faces on boards or the like, namely profiling the end faces, the application of glue and the assembly of the workpieces in one continuous operation without additional times, with high accuracy of fit he follows. This time saving is possible because straightening, milling and putting it together of a workpiece on the same press table and with the precisely aligned, synchronous running milling heads, simultaneously or at least overlapping in time takes place, thus avoiding loss times.
