Description
Die Erfindung betrifft ein Verfahren, mit welchem insbesondere aus Holz oder holzartigem Material bestehende Werkstücke in einfacher und rascher Weise dübelartig verbunden werden können. Der Schreiner sieht zur Verbindung von plattenförmigen Bauteilen an der Stoßstelle Gehrungen vor, die miteinander verleimt werden und mit Hilfe von in Bohrungen oder Nuten eingesetzten Dübeln oder Federn stabilisiert werden. An dieser Technik hat sich seit Jahrhunderten wenig verändert. Zwar sind aus Kunststoff, z. B. aus Polyvenylazetat, Epoxypolyesterharz u. dgl. hergestellte Leime, die in relativ kurzer Zeit abbinden, sowie aus Kunststoff oder Metall bestehende Dübel oder Federn entwickelt worden, jedoch hat sich an der eigentlichen Verbindungstechnik wenig verändert. Stets müssen die miteinander zu verbindenden Teile mit sehr genau angebrachten Bohrungen, Nuten bzw. Dübeln, Zapfen oder Federn versehen werden.The invention relates to a method with which in particular wood or wood-like material existing workpieces can be connected like dowels in a simple and rapid manner. Of the Schreiner provides for the connection of plate-shaped components at the joint before miters, which with each other are glued and with the help of dowels or springs inserted into holes or grooves be stabilized. Little has changed in this technology for centuries. Although are out Plastic, e.g. B. made of polyvinyl acetate, epoxy polyester resin and the like. Glues made in a relatively short Bind time, as well as plastic or metal dowels or springs have been developed, however, little has changed in terms of the actual connection technology. They always have to work together Parts to be connected with very precisely drilled holes, grooves or dowels, tenons or springs are provided.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren vorzuschlagen, bei dem es im Gegensatz zu den bisher bekannten nicht darauf ankommt, daß die Bohrungen oder dergleichen Ausnehmungen bzw. die Zapfen und Dübel an genau vorher bestimmter Stelle plaziert werden. Hierdurch kann es von ungelernten oder zumindest angelernten Kräften ausgeführt werden, ohne daß die Qualität der Verbindung leidet. Vielmehr wird die Festigkeit wesentlich erhöht und gleichzeitig die für den Abbindevorgang notwendige Standzeit als auch die zur Vorbereitung erforderliche Arbeitszeit erheblich verkürzt. Diese Aufgabe wird gemäß der Erfindung durch ein Verfahren gelöst, nach welchem die Werkstücke im Bereich ihrer Stoßstelle mit kommunizierenden Ausnehmungen, wie Bohrungen oder Nuten, versehen werden, in welche rasch erhärtende Materialien im flüssigen oder teigigen Aggregatzustand eingegossen, eingespritzt oder eingepreßt werden.The invention is based on the object of proposing a method in which there is in contrast to the previously known does not matter that the holes or the like recesses or the tenons and dowels are placed at a precisely determined location. Through this it can be carried out by unskilled or at least semi-skilled workers without affecting the quality of the connection suffers. Rather, the strength is significantly increased and at the same time that for the setting process The necessary downtime as well as the working time required for preparation are significantly reduced. This object is achieved according to the invention by a method according to which the workpieces in the area of their joint with communicating recesses, such as holes or grooves are poured into which rapidly hardening materials in the liquid or pasty aggregate state, injected or pressed in.
Als Material zur Verbindung von insbesondere aus Holz oder holzartigem Material bestehenden Werkstücken eignet sich vor allem thermoplastischer Kunststoff, wie z. B. Polyamid, Polykarbonat, Polystyrol, Polyäthylen od. dgl.As a material for connecting in particular made of wood or wood-like material Workpieces are especially suitable for thermoplastic material, such as B. polyamide, polycarbonate, polystyrene, Polyethylene or the like.
Die Vielzahl der zur Verfügung stehenden Kunststoffe gestattet es, die Verbindung den unterschiedlichsten Anforderungen anzupassen. So ist es möglich, sowohl sehr starre als auch sehr elastische Verbindungen nach Maßgabe des ausgewählten Kunststoffes herzustellen. Darüber hinaus können sogar scharnierartig ausgebildete Verbindungen erzeugt werden, wenn als Bindemittel ein sehr elastischer Werkstoff, z. B. Gummi, eingebracht wird.The large number of plastics available allows the connection of the most varied To adapt to requirements. So it is possible to have both very rigid and very elastic connections to produce according to the selected plastic. In addition, they can even be hinged formed connections are created if the binding agent is a very elastic material, z. B. rubber is introduced.
Falls eine widerstandsfähigere Verbindung hergestellt werden soll, kann nach einem weiteren Vorschlag der Erfindung eine zusätzliche Armierung in Form von Drähten od. dgl. vorgesehen werden, welche in den eingespritzten Kunststoff gleichzeitig eingebettet wird.If a more resistant connection is to be established, a further suggestion can be made the invention, an additional reinforcement in the form of wires or the like can be provided, which is embedded in the injected plastic at the same time.
Die bei einer bestimmten Temperatur verflüssigten Kunststoffe können bei der Durchführung des Verfahrens mit an sich bekannten Spritz- oder Preßgußeinrichtungen eingebracht werden. Bei der Verbindung von aus holzartigem Material bestehenden Werkstoffen haben sich thermoplastische Kunststoffe als zweckmäßig erwiesen, die bei einer Temperatur von 200 bis 250° C und bei einem Druck von 50 bis 400 at einen flüssigen oder zumindest teigigen Aggregatzustand haben.The plastics liquefied at a certain temperature can be used in the implementation of the Process can be introduced with known injection or compression molding equipment. When connecting Thermoplastics have proven to be made of materials made of wood-like material Proven to be useful at a temperature of 200 to 250 ° C and at a pressure of 50 up to 400 at have a liquid or at least doughy aggregate state.
Es ist jedoch auch möglich, verflüssigte Verbindungsmaterialien bei normalem Druck einzubringen. Schließlich besteht die Möglichkeit, an sich bekannte, aus mehreren Komponenten bestehende Bindemittel zu verwenden, die erst beim Zusammenfügen der beiden Komponenten abbinden. Hierbei sind die beiden Komponenten erst beim Einbringen in die Ausnehmungen der zu verbindenden Werkstücke zusammenzufügen, worauf sie in bekannter Weise rasch abbinden und hierbei je nach Wahl der Ausgangsstoffe eine starre oder elastische Verbindung entsteht.However, it is also possible to introduce liquefied connecting materials at normal pressure. Finally, there is the possibility of known per se, consisting of several components To use binders that only set when the two components are joined. Here are the two components only when they are introduced into the recesses of the workpieces to be connected join together, whereupon they set quickly in a known manner and this depending on the choice of starting materials a rigid or elastic connection is created.
Während selbst bei Verwendung modernster Leime im Schreinereibetrieb mit Trockenzeiten von 2 bis 8 Minuten gerechnet wurde, ermöglicht das erfindungsgemäße Verfahren eine Verkürzung der Abbindezeit, d. h. der Standzeit, auf weniger als 10 Sekunden. Die derart hergestellte Verbindung ist darüber hinaus weit widerstandsfähiger, was darauf zurückzuführen ist, daß das Bindemittel alle Ausnehmungen, Bohrungen, Fugen und Poren im Bereich der Stoßstellen ausfüllt. Dieser Vorteil tritt insbesondere bei Verwendung poröser Materialien wie z. B. bei Holzspanplatten in Erscheinung, die heute in großem Maße in der Möbelindustrie eingesetzt werden.Even if the most modern glues are used in the joinery business with drying times of 2 to 8 minutes was calculated, the inventive method enables a shortening of the setting time, d. H. the service life to less than 10 seconds. The connection so established is above also far more resistant, which is due to the fact that the binder all recesses, Fills holes, joints and pores in the area of the joints. This advantage occurs in particular when using porous materials such. B. with chipboard in appearance today are widely used in the furniture industry.
Ein weiterer Vorteil ist, daß das erfindungsgemäße Verfahren die Einhaltung wesentlich engerer Toleranzen gestattet, obwohl es von ungelernten oder angelernten Arbeitskräften ausführbar ist. So brauchen die zu verbindenden Teile lediglich in eine geeignet ausgebildete Vorrichtung eingebracht zu werden, wozu es keiner besonderen Fachkenntnis bedarf. Diese Vorrichtung besteht z. B. aus einer an sich bekannten Spritzguß-, Druckguß- oder Preßgußmaschine mit einer oder mehreren Austrittsdüsen, in deren Bereich Spannwerkzeuge zum Einspannen der zu verbindenden Werkstücke angeordnet sind.Another advantage is that the method according to the invention allows for significantly narrower tolerances permitted, although it can be carried out by unskilled or semi-skilled workers. So need the parts to be connected only have to be introduced into a suitably designed device, for which purpose no special expertise is required. This device consists, for. B. from a known per se Injection molding, die casting or compression molding machine with one or more outlet nozzles in their area Clamping tools for clamping the workpieces to be connected are arranged.
Als Spannwerkzeug sind bei einem Ausführungsbeispiel des Gegenstandes der Erfindung gegeneinander vorzugsweise mit Hilfe von Preßluft- oder Hydraulikzylindern betätigbare Spannbacken vorgesehen. Damit das unter Druck eingebrachte, in der Regel flüssige Bindemittel nicht durch die Fugen der Stoßstellen austritt, sind die Spannbacken zweckmäßigerweise derart ausgebildet, daß sie die Fugen der zu verbindenden Werkstücke im Bereich der Stoßstellen überdecken.As a clamping tool are in one embodiment of the subject matter of the invention against each other clamping jaws which can be operated with the aid of compressed air or hydraulic cylinders are preferably provided. So that the usually liquid binding agent introduced under pressure does not get through the joints of the Joints emerges, the clamping jaws are expediently designed such that they close the joints of the workpieces to be connected in the area of the joints.
Derartige Vorrichtungen eignen sich vor allem für die Serienfertigung. Damit sie dennoch möglichst universell angewandt und ausgenutzt werden können, sind die oberhalb und/oder seitlich des Spannwerkzeuges angeordneten Austrittsdüsen verschwenkbar und/oder höhenverstellbar ausgebildet.Such devices are particularly suitable for series production. So that they still as possible Universally applied and exploited are those above and / or to the side of the clamping tool arranged outlet nozzles are designed to be pivotable and / or adjustable in height.
Eine hervorragende Bedeutung hat die Erfindung bei der Verbindung relativ dünner, plattenförmiger, winklig zueinander angeordneter Werkstücke, insbesondere wenn diese aus porösem Material·, ζ. Β. Holzspanplatten, bestehen. Hierfür wurde ein besonderes Spannwerkzeug entwickelt, welches aus einer feststehenden Backe mit entsprechend dem Verbindungswinkel winklig zueinander verlaufenden Anlageflächen und einer gegenüber der ersteren verschiebbaren Spannbacke mit gleichfalls winklig zueinander verlaufenden Druckflächen besteht.The invention is of outstanding importance in the connection of relatively thin, plate-shaped, Workpieces arranged at an angle to one another, especially if they are made of porous material ·, ζ. Β. Chipboard, exist. For this purpose, a special clamping tool was developed, which consists of a fixed Jaw with contact surfaces that run at an angle to one another according to the connection angle and one with respect to the former displaceable clamping jaw also at an angle to one another running pressure surfaces.
Die erfindungsgemäße Technik, nach welcher die zu verbindenden Werkstücke im Bereich der Stoßstelle eine oder mehrere ineinander übergehende, mitThe technique according to the invention, according to which the workpieces to be connected in the area of the joint one or more merging, with
erhärtetem Material gefüllte, quer zur Verbindungsfläche verlaufende Ausnehmungen, wie Bohrungen, Nuten od. dgl. aufweisen, führt zwangläufig zu völlig neuartigen Verbindungselementen.recesses that are filled with hardened material and run transversely to the connecting surface, such as bores, Having grooves or the like inevitably leads to completely new connecting elements.
Zunächst ist es möglich, entsprechend den bisher bekannten Feder- bzw. Dübelverbindungen aus Kunststoff od. dgl. bestehende Elemente in einem Arbeitsgang einzuspritzen. Zu diesem Zweck sind in den Stoßflächen der zu verbindenden Werkstücke Ausnehmungen in Form von senkrecht oder winklig zu den Stoßflächen verlaufenden Nuten oder Bohrungen vorzusehen. In neuartiger Weise ist es jedoch auch möglich, den Nuten einen Schwalbenschwanzartigen Querschnitt zu geben, wodurch die Festigkeit der Verbindung wesentlich erhöht wird. Weiterhin können sich im Bereich der Stoßflächen überkreuzende Nuten mit den Bindemitteln gefüllt werden.First of all, it is possible to use the previously known spring or dowel connections To inject plastic or the like existing elements in one operation. For this purpose, in the abutting surfaces of the workpieces to be connected, recesses in the form of perpendicular or angled to provide grooves or bores running towards the abutment surfaces. In a novel way, however, it is also possible to give the grooves a dovetail-like cross-section, which increases the strength the connection is increased significantly. Furthermore, in the area of the abutment surfaces intersecting Grooves are filled with the binders.
Schließlich wurde eine Verbindungsart entwickelt, bei welcher vorzugsweise auf der Außenfläche der zu verbindenden Werkstücke ineinander übergehende ao Nuten eingefräst sind, in welche eine Vielzahl von die beiden Werkstücke durchsetzende, kommunizierende Bohrungen münden. Hierdurch ist eine außerordentlich stabile Eckverbindung erzielbar.Finally, a type of connection was developed in which preferably on the outer surface of the to connecting workpieces into one another merging ao grooves are milled into which a large number of the two workpieces penetrating, communicating bores open. This is an extraordinary one stable corner connection achievable.
Das erfindungsgemäße Verfahren vereinfacht und verbessert nicht nur die Verbindung plattenförmiger Werkstoffe, sondern auch die Verbindung von Leisten, wie sie insbesondere bei der Herstellung von Stühlen, Rahmen od. dgl. erforderlich ist. Sollen z. B. im Bereich eines Stuhlbeines drei oder mehrere leistenförmige Werkstücke miteinander verbunden werden, ist lediglich ein mittleres Werkstück mit einer Einfüllbohrung zu versehen, in welche mehrere, die übrigen Werkstücke durchsetzende, miteinander verbundene Bohrungen münden. Durch Einbringen des Bindematerials in erfindungsgemäßer Weise werden die drei Teile mit einer Festigkeit verbunden, die mit der hergebrachten Verleimungstechnik bislang nicht erzielbar war.The method according to the invention not only simplifies and improves the plate-shaped connection Materials, but also the connection of strips, such as those used in particular in the manufacture of Chairs, frames or the like. Is required. Should z. B. three or more strip-shaped in the area of a chair leg Workpieces are connected to each other, is only a middle workpiece with a To provide filling hole, in which several, the other workpieces penetrating, interconnected Open holes. By introducing the binding material in a manner according to the invention the three parts are connected with a strength that has not yet been achieved with traditional gluing technology was achievable.
