Description

Die Erfindung betrifft eine Vorrichtung zum Einsetzen von Verbindungselementen in die Stirn- und/oder Längsseiten technischer Holzprodukte.The invention relates to a device for inserting connecting elements in the front and / or long sides of technical wood products.

Es ist bekannt, technische Holzprodukte, wie Fußbodenpaneele, Möbelplatten, MDF- Platten, HDF- Platten OSB-Platten u.ä. im kontinuierlichen Betrieb zu fertigen. Zum Zusammenfügen der vorgenannten technischen Holzprodukte zu größeren zusammenhängenden Gebilden, wie Fußböden, Wänden, Möbeln werden diese an den äußeren Längs- und / oder Stirnseiten mit Verbindungselementen versehen, allgemein als Nut- Feder- Verbindung bekannt. Die Verbindungselemente werden dabei aus dem technischen Holzprodukt herausgefräst. Nachteilig ist, dass die aus den Holzprodukten herausgefrästen Federn beim Transport beschädigt werden können und herausbrechen. Insbesondere bei Fußbodenpaneelen kann es bei den Stirnseiten bei teilweiser herausgebrochener Feder zu Komplikationen beim Zusammenbau führen, was zu einer Minderung der Verbindungsfestigkeit führt.It is known technical wood products, such as floor panels, furniture panels, MDF boards, HDF boards OSB boards and the like. to produce in continuous operation. For joining the aforementioned technical wood products to larger contiguous structures, such as floors, walls, furniture these are provided on the outer longitudinal and / or end faces with connecting elements, commonly known as tongue and groove connection. The fasteners are milled out of the technical wood product. The disadvantage is that the milled out of the wood products springs can be damaged during transport and break out. Especially with floor panels, it can lead to complications during assembly at the end faces with partially broken spring, resulting in a reduction of the connection strength.

Aus der CH-Patentschrift 24980 ist eine Maschine zur Herstellung von Platten aus Holzklötzchen bekannt. Dabei werden die Holzklötzchen, die auf zwei sich gegenüberliegenden Seiten Nuten aufweisen aus einer Bevorratung in mehreren Reihen nebeneinander und hintereinander liegend einem Tisch mit Pressschlitten zugeführt. Auf dem Tisch werden in die Nuten der Holzklötzchen Federn eingepresst. Die Federn werden aus Magazinen, in notwendiger Anzahl nebeneinander gelagert sind gleichzeitig in die Nuten der Holzklötzchen eingepresst. Nachdem eine Platte hergestellt wurde, wird diese entfernt und der Vorgang für die nächste Platte beginnt. Mit dieser Maschine ist nur eine diskontinuierliche Produktion möglich, wobei aus einzelnen Holzteilen ein größeres Holzprodukt entsteht. Durch den hohen Druck beim Einpressen der Federn kommt es leicht zum Zerbrechen der Feder oder Ausbrechen der Nut und damit zu einem schlechten Zusammenfügen der Einzelteile mit verminderter Festigkeit. Das Zusammenfügen der Einzelteile kann nur in der Produktionsstätte erfolgen.From the Swiss Patent 24980 is known a machine for making slabs of wooden blocks. The wooden blocks, which have grooves on two opposite sides of a storage in several rows next to each other and one behind the other lying a table supplied with press carriage. On the table, springs are pressed into the grooves of the wooden blocks. The springs are stored in magazines, in necessary number next to each other are pressed simultaneously into the grooves of the wooden blocks. After a plate is made, it is removed and the process for the next plate begins. With this machine, only a discontinuous production is possible, resulting in a larger wood product from individual pieces of wood. Due to the high pressure when pressing in the springs, it is easy to break the spring or breakout of the groove and thus poor assembly of the items with reduced strength. The assembly of the individual parts can only be done in the production facility.

Des Weiteren ist aus der DE 142 293 ein Verfahren zur Herstellung von Bodenplatten aus Prismenstücken bekannt. Die Prismenstücke werden durch von sich kreuzenden Verbindungsstäben zusammengehalten. Die Verbindungsstäbe fallen zum Zusammenfügen der Prismenstücke aus einem oberhalb des Liegeplatzes der Prismenstäbe angeordneten Magazins auf die Nut in den Prismenstücken und werden durch einen Stempel in die Nut gepresst. Eine Übergabevorrichtung für die Verbindungsstäbe wird nicht eingesetzt und der Verbindungsstab wird über seine gesamte Länge in einem Pressvorgang bei ortsfest angeordneten Prismenstücken eingebracht. Ein solches Verfahren lässt nur eine diskontinuierliche Zusammenfügung der Prismenstücke erreichen.Furthermore, from the DE 142 293 a method for producing floor slabs from prism pieces known. The prism pieces are held together by intersecting connecting rods. The connecting rods are for joining the prism pieces of a arranged above the mooring of the prism bars magazine on the groove in the prism pieces and are pressed by a punch in the groove. A transfer device for the connecting rods is not used and the connecting rod is introduced over its entire length in a pressing operation with fixed prism pieces. Such a procedure leaves only one achieve discontinuous assembly of the prism pieces.

Man ist deshalb dazu übergegangen, in die Holzprodukte, an den Stirn- und/oder Längsseiten jeweils eine Nut einzufräsen und erst beim Verarbeiten die Federn einzusetzen. Das erfordert einen hohen Zeitaufwand, da die Federn erst auf die gewünschte Länge geschnitten und dann mit Vorsicht in die Nut einer Stirn- und/oder Längsseite eingepasst werden müssen. Ein schiefes Ansetzen der Federn kann zum Ausbrechen oder teilweisen Ausbrechen der Nut führen.It has therefore gone over to milled in the wood products, on the front and / or longitudinal sides in each case a groove and to use only when processing the springs. This requires a lot of time, since the springs must first be cut to the desired length and then fitted with care in the groove of a front and / or long side. An oblique application of the springs can lead to breaking or partial breaking of the groove.

Aus der DE-Offenlegungsschrift 100 34 409 A1 ist eine Einrichtung zum Verbinden von Bauplatten mit einem Kern aus Holzwerkstoff bekannt. Hier werden die auf zwei sich gegenüberliegenden Seitenkanten mit einer Nut versehenen Bauplatten mit einem Verbindungselement zusammengefügt. Das Verbindungselement, eine in der Holzindustrie bekannte Feder, weist spiegelsymmetrisch zu seiner Mitte auf jeder Seite eine Mehrzahl von Widerhaken auf. Durch die Widerhaken wird ein besseres Haftvermögen der Feder in den Nuten der zusammenzufügenden Teile, zum Beispiel Bodenpaneele zu Bauplatten, erreicht. Die Verbindungselemente entsprechen in der Länge den Nuten in den zusammenzufügenden Teilen, wobei die Verbindungselemente am Ort der Verarbeitung eingesetzt werden. Auch hier kommt es oft zum Ausbrechen oder teilweisen Ausbrechen der Nut und damit zu einer schlechten Verbindung der einzelnen zusammenzufügenden Holzteile.From the DE-Offenlegungsschrift 100 34 409 A1 a device for connecting structural panels with a core of wood-based material is known. Here, the building panels provided with a groove on two opposite side edges are joined together with a connecting element. The connecting element, a spring known in the wood industry, has a plurality of barbs symmetrically symmetrical about its center on each side. By the barbs a better adhesion of the spring in the grooves of the parts to be joined, for example, floor panels to building boards, achieved. The connecting elements correspond in length to the grooves in the parts to be joined, wherein the connecting elements are used at the place of processing. Again, it often comes to breaking or partial breaking out of the groove and thus to a poor connection of the individual pieces of wood to be joined together.

In der vorangemeldeten EP 1 582 653 wird die Einbringung einer Feder in eine Nut von Holzprodukten im kontinuierlichen Betrieb beschrieben, jedoch dient zur Aufnahme der Feder ein seitlich neben der Transporteinrichtung angeordnetes Magazin. Die seitliche Anordnung des Magazins neben der Transporteinrichtung macht einen neben der Transporteinrichtung vorgesehenen Mitnehmer, der als in Richtung der Magazine vorhandenen Stift ausgebildet ist und um eine Achse quer zur Transporteinrichtung schwenkbar und linear verschiebbar ist.In the pre-registered EP 1 582 653 the introduction of a spring is described in a groove of wood products in continuous operation, however, serves to receive the spring arranged laterally next to the transport device magazine. The lateral Arrangement of the magazine next to the transport device makes a provided next to the transport means driver, which is designed as existing in the direction of the magazine pen and is pivotable about an axis transverse to the transport device and linearly displaceable.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zu schaffen, bei der die Verbindungselemente industriell in den kontinuierlich laufenden Produktionsprozess der Herstellung der technischen Holzprodukte, beispielsweise Fußbodenpaneele in die Stirn- und/oder Längsseite der technischen Holzprodukte eingefügt werden.The invention has for its object to provide a device in which the connecting elements are industrially inserted into the continuous production process of the production of technical wood products, such as floor panels in the front and / or long side of the technical wood products.

Erfindungsgemäß wird die Aufgabe durch eine Vorrichtung mit den Merkmalen des Anspruches 1 gelöst. Besondere Ausgestaltungen finden sich in den kennzeichnenden Merkmalen der Unteransprüche.According to the invention the object is achieved by a device having the features of claim 1. Particular embodiments can be found in the characterizing features of the subclaims.

Erfindungsgemäß besteht die Vorrichtung zum Einsetzen von Verbindungselementen aus einem oder mehreren an einer Längsseite der Transporteinrichtung für die technischen Holzprodukte zur Aufnahme der Verbindungselemente angeordneten Magazinen, die oberhalb oder unterhalb der Transporteinrichtung angeordnet sind, einer Übergabevorrichtung für die Verbindungselemente von dem/ den Magazin/en zum Einpressaggregat, ebenso können die Verbindungselemente von einer endlosen Bevorratung kommend der Übergabevorrichtung zugeführt werden, wobei sie unmittelbar vor oder in der Übergabevorrichtung auf die gewünschte Länge geschnitten werden und einem quer zur Förderrichtung der technischen Holzprodukte verfahrbaren Einpressaggregat oder einer quer zur Fördervorrichtung der technischen Holzprodukte angeordneten schiefen Ebene oder einer Anpressrolle als Einpressaggregat zugeführt werden.According to the invention, the device for inserting connecting elements from one or more arranged on a longitudinal side of the transport device for the technical wood products for receiving the fasteners magazines, which are arranged above or below the transport device, a transfer device for the connecting elements of the / the magazine / s Einpressaggregat, as well, the connecting elements can be supplied from an endless storage coming from the transfer device, where they are cut immediately before or in the transfer device to the desired length and obliquely to the conveying direction of the technical wood products traversable Einpressaggregat or arranged transversely to the conveying device of technical wood products Level or a pressure roller are fed as Einpressaggregat.

Bei der erfindungsgemäßen Einrichtung werden die Verbindungselemente, die aus Holz oder Kunststoff bestehen, auf die gewünschte Länge geschnitten und bei einer Variante in Magazine eingeordnet. Dabei können in den jeweiligen Magazinen Verbindungselemente unterschiedlicher Länge oder aber gleicher Länge abgelegt werden. Bei den Magazinen mit Verbindungselementen gleicher Länge kann ein leeres gegen ein volles Magazin bei laufender Produktion ausgetauscht werden.In the device according to the invention, the connecting elements, which consist of wood or plastic, cut to the desired length and arranged in a variant in magazines. In this case, connecting elements of different lengths or the same length can be stored in the respective magazines. For the magazines with fasteners of the same length, an empty can be exchanged for a full magazine during production.

Bei einer anderen Variante werden vorkonfektionierte Verbindungselemente auf einem Band sortiert, in die gewünschte Richtung positioniert, der Übergabevorrichtung zugeführt.In another variant, pre-assembled connecting elements are sorted on a belt, positioned in the desired direction, fed to the transfer device.

Bei einer weiteren Variante ist die Bevorratung für die Verbindungselemente als Sortiertopf ausgebildet, der in einer horizontalen Ebene oberhalb oder unterhalb der horizontalen Ebene des Transports der Holzprodukte angeordnet ist. Mittels des Sortiertopfes werden ungeordnet zugeführte Verbindungselemente vereinzelt und ausgerichtet an die Übergabevorrichtung übergeben. Die Übergabevorrichtung besteht dabei beispielsweise aus einem ungetakteten und einem getakteten Riemenförderer. Der ungetaktete Riemenförderer weist einen Transportriemen und einen Druckriemen auf. Die Verbindungselemente werden zwischen dem Transportriemen und dem Druckriemen des ungetakteten Riemenförderers durch Klemmung gehalten und durch die Wirkung der Reibkraft zwischen der Oberfläche des Verbindungselementes und der Oberfläche mindestens eines der beiden Riemen transportiert. Der Transport erfolgt dabei von der horizontalen Ebene des Sortiertopfes in die horizontale Ebene des Transports der Holzprodukte. Nach Umlenkung der Richtung des ungetakteten Riemenförderers, die mittels Riemenscheiben geschieht, erfolgt die Übergabe des Verbindungselementes von dem ungetakteten Riemenförderer an den getakteten Riemenförderer. Dabei wird ein erstes Verbindungselement unterhalb des getakteten Riemenförderers gegen einen nicht dargestellten Anschlag gefördert und ein zweites, dem ersten Verbindungselement nachfolgendes Verbindungselement wird gegen das erste Verbindungselement gefördert und so fort. Dabei rutschen sowohl der Transportriemen als auch der Druckriemen des ungetakteten Riemenförderers unter Überwindung der zuvor zum Transport genutzten Reibkraft über die Verbindungselemente hinweg. Das erste Verbindungselement wird entsprechend der gewählten Taktung von dem getakteten Riemenförderer aus dieser quasi Wartestellung übernommen und so fort.In a further variant, the storage for the connecting elements is designed as a sorting pot, which is arranged in a horizontal plane above or below the horizontal plane of transport of the wood products. By means of the sorting pot, randomly supplied connecting elements are separated and transferred in an aligned manner to the transfer device. The transfer device consists for example of an untacted and a clocked belt conveyor. The untimed belt conveyor has a transport belt and a pressure belt. The connecting elements are clamped between the transport belt and the pressure belt of the untimed belt conveyor and transported by the action of frictional force between the surface of the connecting element and the surface of at least one of the two belts. The transport takes place from the horizontal plane of the sorting pot in the horizontal plane of transport of wood products. After redirecting the Direction of the untimed belt conveyor, which is done by means of pulleys, there is the transfer of the connecting element from the untimed belt conveyor to the clocked belt conveyor. In this case, a first connecting element is conveyed below the clocked belt conveyor against a stop, not shown, and a second, the first connecting element subsequent connecting element is conveyed against the first connecting element and so on. Both the conveyor belt and the pressure belt of the untimed belt conveyor slip over the connecting elements, overcoming the frictional force previously used for transport. The first connecting element is taken over by the clocked belt conveyor from this quasi waiting position according to the selected timing and so on.

Anstelle des Sortiertopfes ist in einer anderen Variante auch der Einsatz einer Kaskadensortierung für die Verbindungselemente möglich, die wiederum oberhalb als auch unterhalb der horizontalen Ebene des Transportes der Holzprodukte angeordnet ist.Instead of the sorting pot in another variant, the use of a cascade sorting for the connecting elements is possible, which in turn is arranged above and below the horizontal plane of transport of the wood products.

Bei Verwendung von Magazinen werden die einzelnen Verbindungselemente mit der Übergabevorrichtung aus einem Magazin erfasst, auf die Höhe der Nut in den technischen Holzprodukten gebracht und dem Einpressaggregat zugeführt. Die Übergabevorrichtung für die Zuführung der Verbindungselemente arbeitet mit den Mitnehmern für die technischen Holzwerkstoffe auf der Förderstrecke programmgesteuert zusammen. Dadurch ist gewährleistet, dass die Verbindungselemente passgenau in eine stirn- oder längsseitige Nut der technischen Holzprodukte eingeführt werden.When using magazines, the individual fasteners are detected with the transfer device from a magazine, brought to the height of the groove in the technical wood products and fed to the Einpressaggregat. The transfer device for the supply of the connecting elements works together programmatically with the carriers for the technical wood-based materials on the conveyor line. This ensures that the connecting elements are accurately inserted into a frontal or longitudinal groove of the technical wood products.

In einer besonderen Ausgestaltung der erfindungsgemäßen Einrichtung werden die Verbindungselemente und die technischen Holzprodukte über einen gemeinsamen Mitnehmer erfasst und der Verarbeitung zugeführt.In a particular embodiment of the device according to the invention, the connecting elements and the technical wood products are detected by a common driver and fed to the processing.

Wird als Einpressaggregat eine schiefe Ebene oder eine Anpressrolle verwandt, so wird das durch die Übergabevorrichtung gehaltene Verbindungselement mit seinem in Förderrichtung zeigenden Ende in das vorn liegende Ende der stirn- oder längsseitigen Nut der technischen Holzprodukte eingehakt. Beim Weitertransport der technischen Holzprodukte wird das Verbindungselement problemlos vollständig durch die schiefe Ebene oder die Anpressrolle in gewünschter Weise in die Nut eingedrückt.If an inclined plane or a pressure roller is used as an injection unit, the connecting element held by the transfer device is hooked with its end pointing in the conveying direction into the front end of the frontal or longitudinal groove of the technical wood products. During further transport of technical wood products, the connecting element is easily pressed completely by the inclined plane or the pressure roller in the desired manner in the groove.

Wird als Einpressaggregat eine quer zur Fördervorrichtung der technischen Holzprodukte arbeitende Anordnung angesetzt, so wird das Verbindungselement von der Übergabevorrichtung erfasst und auf die passende Höhe zur Nut der technischen Holzprodukte geführt und parallel zu den Abmessungen des gerade auf der Förderanlage aufliegenden technischen Holzproduktes gehalten. Sodann wird durch Querfahren der Einpressanordnung das Verbindungselement in die Nut eingedrückt.Is applied as a press-fitting a transversely to the conveyor of the technical wood products working arrangement, the connecting element is detected by the transfer device and guided to the appropriate height to the groove of the technical wood products and kept parallel to the dimensions of the currently resting on the conveyor technical wood product. Then the connecting element is pressed into the groove by transversely driving the press-fit.

Die Einpressanordnung wird durch ein linear bewegtes oder über einen Kurvenläufer beeinflusstes Hubsystem angetrieben.The Einpressanordnung is driven by a linearly moved or influenced by a cam rotor lifting system.

Während des Querfahrens der Einpressanordnung wird diese in der Geschwindigkeit des Förderbandes in Förderrichtung verschoben. Selbstverständlich erfolgen diese Arbeitsgänge ebenfalls programmgesteuert.During the transverse travel of the press-in arrangement, it is displaced in the conveying direction at the speed of the conveyor belt. Of course, these operations are also programmatically.

Die mit einem Verbindungselement zu versehenden technischen Holzprodukte werden auf dem Förderband parallel ausgerichtet dem Einpressaggregat zugeführt. Das wird durch die auf dem Förderband vorgesehenen Mitnehmer für die technischen Holzprodukte und durch ein auf der gegenüberliegenden Seite des Einpressaggregates angeordnetes Gegenlager erreicht.The technical wood products to be provided with a connecting element are fed in parallel on the conveyor belt to the press-in unit. This is achieved by the driver provided for on the conveyor for the technical wood products and by a arranged on the opposite side of the Einpressaggregates abutment.
