Description
Die Erfindung betrifft eine Einrichtung zur kontinuierlichen Herstellung einer mit einer Dekorschicht kaschierten Spanholzbahn, bestehend aus einer beheizten und sich drehenden Trommel größeren Durchmessers, sich über einen Teil des Umfangs der Trommel erstreckenden mitlaufenden Andrückeinrichtungen und aus Einrichtungen ^um Zuführen der zu beschichtenden IMaterialbahn und des Beschichtungsmaterials zwischen die Andrückeinrichtungen und die Trommel in der Weise, daß das Beschichtungsmaterial der Trommel zugewandt ist.The invention relates to a device for the continuous production of one with a decorative layer Laminated chipboard web, consisting of a heated and rotating drum of larger diameter, revolving pressure devices extending over part of the circumference of the drum and from facilities ^ to supply the to be coated IMaterial web and the coating material between the pressure devices and the drum in the Way that the coating material faces the drum.
Aus der CH-PS 5 13 721 if.; eine i inrichtung bekannt zur kontinuierlichen Herstelling von Spanplattenbahren, wobei das zu verpressende mit nem Bindemittel imprägnierte Spanmaterial auf ein endloses, unter Zugspannung stehendes Stahlband aufgestreut und zwischen diesem und einer beheizten, sich drehenden Preßtrommel kontinuierlich zu einer Bahn verpreßt wird.From CH-PS 5 13 721 if .; an i known establishment for the continuous production of chipboard stretchers, whereby the chip material to be pressed, impregnated with a binder, is placed on an endless, underneath Tensile stress standing steel strip scattered and between this and a heated, rotating Press drum is continuously pressed into a web.
In den nicht vorveröffentlichten Druckschriften DE-OS 22 01 136 und DE-AS 22 01 302 sind Einrichtungen der eingangs genannten Art vorgeschlagen mit einer zentralen, beheizten und sich drehenden Preßtrommel, die teilweise von einem endlosen, unter Zugspannung stehenden Stahlband umschlungen wird. Diese Einrichtungen werden zum kontinuierlichen Kaschieren von Spanholzbahnen mit einer Dekorschicht eingesetzt, wobei zwischen dem endlosen Stahlband und der beheizten Preßtrommel die Bahn kaschiert wird.In the unpublished documents DE-OS 22 01 136 and DE-AS 22 01 302 are devices proposed of the type mentioned with a central, heated and rotating press drum, which is partially wrapped by an endless steel band under tension. These devices are used for the continuous lamination of chipboard strips with a decorative layer used, with the web between the endless steel belt and the heated press drum is concealed.
Mittels des endlosen, unter Zugspannung stehenden Stahlbandes wird auf die zu kaschierende Materialbahn tin Flächendruck ausgeübt, der in Verbindung mit der Von der Preßtrommel ausgehenden Temperatur den Kaschiervorgang bewirkt.The material web to be laminated is applied by means of the endless steel belt, which is under tension tin surface pressure exerted in connection with the temperature emanating from the press drum Laminating process causes.
Aus der GB-PS 10 49 584 ist eine Einrichtung der eingangs genannten Art bekannt. Als Andrückeinrichlungen ist ebenfalls ein Stahlband vorgesehen. Die Einrichtung dient nicht der Kaschierung von Spanholzbahnen. From GB-PS 10 49 584 a device of the type mentioned is known. As pressure devices a steel band is also provided. The device is not used to cover chipboard strips.
Eiiie Käschiereiririchtüng mit einem endlosen Stahlband ist unwirtschaftlich, weil das Stahlband, bedingt durch die vielen Biegewechsel während des Umlaufs um die zentrale Preßtrommel und die Umlenke und Spannwalzen, nur eine kurze Lebensdauer hat. Um auf der anderen Seite den auf das Material auszuübenden Flachendruck so groß wie möglich zu halten, muß das endlose Stahlband sehr stark gespannt werden. Daher muß das Stahlband aus einem hochfesten Stahl, der große Zugkräfte standhält, bestehen, d. h., es muß ein sehr teurer SpezialStahl eingesetzt werden.A cashier direction with an endless steel belt is uneconomical because the steel belt is conditional due to the many bending cycles during rotation the central press drum and the deflectors and tension rollers, only has a short lifespan. In order to On the other hand, to keep the surface pressure to be exerted on the material as great as possible, this has to be done endless steel belt can be very tightly tensioned. Therefore, the steel band must be made of a high-strength steel that withstand large tensile forces, exist, d. i.e., it must be a very expensive special steel can be used.
Der Kaschiervorgang entlang des Umfangs einer beheizten Trommel größeren Durchmessers hat sich auf der anderen Seite deswegen als optimal erwiesen, weil die Aufheizung des zu kaschierenden Materials sehr schnell und gleichmäßig erfolgt. Der Aufheizvoigang des Materials durch Herumführen um eine beheizte Trommel größeren Durchmessers ist daher unübertroffen, weil ein inniger Kontakt zwischen der zu kaschierenden Bahn und der Heizquelle, d. h., der zentralen Trommel, hergestellt wird, der für eine bestimmte Zeit, entsprechend der Länge der Umschlingung, aufrechterhalten wird.The lamination process along the circumference of a heated drum of larger diameter has emerged on the other hand, it has proven to be optimal because the material to be laminated is heated up a lot done quickly and evenly. The heating process of the material by passing it around a heated drum of larger diameter is therefore unsurpassed, because an intimate contact between the web to be laminated and the heating source, d. h., the central drum, which is made for a certain time, according to the length of the wrap, is maintained.
Weiterhin sind Einrichtungen zum Kaschieren von Bahnen bekannt, die den Kaschiervorgang in einem Walzenspalt durchführen (GB-PS 10 17 154, GB-PS 12 95 536, DE-GM 19 69 546, DE-AS 10 92 145 und »Holz als Roh- und Werkstoff«, Dezember 1969, Heft 12, Seite 459). Das Trägermaterial und auch die Dekorschicht werden dabei durch Infrarot- oder anderen Heizungen aufgewärmt und einem Walzenspalt zugeführt, um miteinander verbunden zu werden. Wenn eine Dekorbahn in gespanntem Zustand aufgewärmt wird, erfährt sie eine .' ängung, die zu Faltenbildungen führt. Bei der Kaschierung des Trägermaterials und der Dekorschicht zusammen mit dem Haftvermittler in einem Walzenspalt kann somit nicht ausgeschlossen werden, daß durch die Faltenbildung der Dekorschicht diese Schicht im Walzenspalt zerstört wird. Wenn jedoch von einer Aufheizung der auf das Trägermaterial aufzukaschierenden Schicht abgesehen wird, um Faltenbildungen zu vermeiden und statt dessen nur die Trägerschicht aufgeheizt wird (DE-AS 10 92 145). kann nicht sichergestellt werden, daß ein ausreichender Verbund zustandekommt, zumal nur Liniendruck auf beide Bahnen ausgeübt wird. Auf dies«· Weise läßt sich eine hochwertige Kaschierung nicht erzielen.Furthermore, devices for lamination of webs are known that the lamination process in one Perform roller gap (GB-PS 10 17 154, GB-PS 12 95 536, DE-GM 19 69 546, DE-AS 10 92 145 and "Wood as raw and material", December 1969, issue 12, page 459). The carrier material and also the Decorative layers are warmed up by infrared or other heaters and a roller gap fed to be connected to each other. When a decorative sheet is warmed up in a stretched state she experiences one. ' constriction that leads to wrinkles leads. When laminating the carrier material and the decorative layer together with the adhesion promoter in a nip can therefore not be ruled out that the decorative layer is wrinkled this layer is destroyed in the nip. However, if there is any heating on the carrier material to be laminated layer is disregarded in order to avoid wrinkles and instead only the Carrier layer is heated (DE-AS 10 92 145). can not be guaranteed that a sufficient Composite comes about, especially since only line pressure is exerted on both tracks. In this way one can a high quality lamination cannot be achieved.
Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der eingangs genannten Art zum kontinuierlichen Kaschieren aufzuzeigen, mit der die Kaschierung von Spanholzbahnen ohne die Gefahr von Faltenbildung ohnr I insatz eines aufwendigen Stahlbandes möglich ist.The invention is based on the object of a device of the type mentioned for continuous To show lamination, with which the lamination of chipboard sheets without the risk of Wrinkling is possible without using an expensive steel belt.
Die Lösung dieser Aufgabe besteht gemäß der Erfindung darin, daß die Andruckeinrichtungen aus mehreren Walzen kleineren Durchmessers bestehen, die mechanisch, pneumatisch oder hydraulisch gegen die Trommel gepreßt werden.The solution to this problem is according to the invention that the pressure devices from several rollers of smaller diameter exist, which mechanically, pneumatically or hydraulically against the Drum are pressed.
Bei dieser Einrichtung ist das die Trommel umschlingenae Stahlband vermieden und durch kleinere, gegen die Trommel gedrückte Walzen ersetzt. Die Möglichkeit des gleichmäßigen Aufheizens des Beschichtungsmaterials und des Verbindens der Materialien längs eines Teils des Umfangs der beheizten Trommel ist aber dennoch erhalten geblieben. Beim Betrieb Jer Einrichtung wird das Beschichtungsmaterial im ersten Spalt zwischen der Trommel und der ersten kleineren Walze teilweise verbunden und gegen die beheizte Trommel gepreßt. Dadurch ist zunächst eine sichere Führung herbeigeführt. In den zwischen der Trommel und den Weiteren Walzen gebildeten Weiteren Spalten wird der Verbund weiter verfestigt. Es hat sich überraschend gezeigt, daß die zu kaschierende Spanholzbahri, die von der beheizten Trommel abgewandt ist, hinreichend starrWith this device, the steel belt wrapped around the drum is avoided and by smaller, against the drum replaced pressed rollers. The possibility of uniform heating of the coating material and bonding the materials along a portion of the periphery of the heated drum still preserved. When operating the facility, the coating material is in the first gap partially connected between the drum and the first smaller roller and against the heated drum pressed. This is initially a safe leadership brought about. In the between the drum and the Further columns formed by further rollers will be the Bond further strengthened. It got surprising shown that the chipboard to be laminated, which faces away from the heated drum, is sufficiently rigid
ist, so daß alle Schichten ständig auch zwischen den Walzen gegen die Trommel gepreßt werden. Dadurch tritt keinerlei Faltenbildung auf, und auch die beim Einsatz eines Stahlbandes vorhandene sehr schnelle und sehr gleichmäßige Wärmeübergabe von der Trommel 5 bleibt erhalten.is, so that all layers are constantly pressed against the drum between the rollers. Through this there is no wrinkling whatsoever, and also the very fast and easy that occurs when a steel belt is used very even heat transfer from the drum 5 is retained.
Kleinere Walzen sind verglichen mit den normalerweise aus einem Spezialstah! bestehenden Band preiswerte Bauteile. Außerdem fallen die für das endlose Stahlband bisher erforderlichen L'mlenk- und Spann- iq walzen sowie die Spanneinrichtung selbst weg.Smaller rollers are usually made of a special steel compared to the normal ones! existing band inexpensive components. In addition, the steering and tensioning iq previously required for the endless steel belt roll away as well as the clamping device itself.
Soll eine Spanholzbahn von beiden Seiten mit einer Dekorschicht kaschiert werden, so ist es möglich, die Spanholzbahn in entsprechender Weise durch zwei hintereinander angeordnete Einrichtungen der vorgeschlagenen Art hindurchzuführen.If a chipboard sheet is to be covered with a decorative layer on both sides, it is possible to use the Chipboard web in a corresponding manner by two devices arranged one behind the other of the proposed Kind of lead through.
In der Zeichnung sind zwei Ausführungsbeispiele der erfindungsgemäßen Einrichtung schematisch dargestellt. Two exemplary embodiments of the device according to the invention are shown schematically in the drawing.
Fig. 1 zeigt eine Kaschiereinrichtung im Querschnitt zum einseitigen Kaschieren einer Spanholzbahn.Fig. 1 shows a concealment device in cross section for one-sided lamination of a chipboard sheet.
Fig.2 zeigt eine Kaschiereinrichtung im Querschnitt zum beidseitigen Kaschieren einer Spanholzbahr·2 shows a concealment device in cross section for laminating a chipboard stretcher on both sides
In Fig. 1 ist die Trommel 1 größeren Durchmessers beheizt und die Walzen 2 bis 5 kleineren Durchmessers pressen das zu kaschierende Material gegen die beheizte Trommel 1.In Fig. 1, the drum 1 is of larger diameter heated and the rollers 2 to 5 smaller diameter press the material to be laminated against the heated drum 1.
Eine dünne Spanholzbahn 6 läuft zusammen mit einem bahnförmigen Haftvermittler 8 und einer Dekorschicht 7 in den Spalt zwischen der beheizten Trommel 1 und der Walze 2 ein und wird in den Spalten zwischen den Walzen 2, 3, 4 und 5 und der beheizten Trommel 1 mit der Dekorschicht verbunden. Die einseitig kaschierte Spanholzbahn 10 kann dann in einer Einrichtung, bestehend aus Walzen 9, 9a, mattiert oder geprägt werden, je nachdem aus welchem Material die Dekorschicht besteht.A thin chipboard web 6 runs together with a web-shaped adhesion promoter 8 and one Decorative layer 7 in the gap between the heated drum 1 and the roller 2 and is in the gaps connected between the rollers 2, 3, 4 and 5 and the heated drum 1 with the decorative layer. the One-sided laminated chipboard web 10 can then in a device consisting of rollers 9, 9a, matted or be embossed, depending on what material the decorative layer is made of.
In Fig.2 wird eine ähnliche Einrichtung gezeigt, mit der es möglich ist, eine Spanholzbahn 25 beidseitig mit Dekorschichten 26 und 30 mittels Haftvermittler 27 und 29 zu kaschieren. Die Trommeln 21 und 31 sind jeweils beheizt und das zu kaschierende Material wird durch die Walzen 22 bis 24 und 32 bis 34 gegen die beheizten Trommeln gepreßt. Die beidseitig mit Dekorschichten kaschierte Spanholzbahn 36 kann dann durch eine Prägeinrichtung 35, bestehend aus zwei Walzen, laufen und wird anschließend einer nicht gezeigten Schneid- und Stapeleinrichtung zugeführt.In Fig.2 a similar device is shown, with which it is possible to have a chipboard web 25 on both sides with decorative layers 26 and 30 by means of adhesion promoters 27 and 29 to conceal. The drums 21 and 31 are each heated and the material to be laminated is through the Rolls 22 to 24 and 32 to 34 pressed against the heated drums. The two-sided with decorative layers Laminated chipboard web 36 can then run through an embossing device 35 consisting of two rollers and is then fed to a cutting and stacking device, not shown.
Die Temperaturanpassung beim Kaschieren verschiedener Materialien der Trommeltemperatur ist bekannL Wenn beispielsweise die Dekorschicht eine Papierschicht ist, muß selbstverständlich eine andere Temperatur gewählt werden als bei einer Dekorschicht aus einem Gewebe bzw. aus Kunststoff.The temperature adjustment of the drum temperature when laminating different materials is known If, for example, the decorative layer is a paper layer, a different temperature must of course can be selected as with a decorative layer made of a fabric or made of plastic.
Als Dekorschicht für die Spanholzbahnen kommen bedruckte Papiere, Stoffbahnen und andere Gewebebahnen, Faservliese und auch Kunststoffbahnen oder andere Materialien je nach Verwendungszweck der kaschierten Spanholzbahn in Betracht.As a decorative layer for the chipboard sheets, printed paper, fabric sheets and other fabric sheets are used, Fiber fleece and also plastic sheeting or other materials depending on the intended use of the laminated chipboard into consideration.
Vorzugsweise werden bahnförmige Haftvermittler eingesetzt, beispielsweise längsgereckte Kunststoffolien, weil diese sich beim Erwärmen spannen und somit eine ausgezeichnete Haftung bzw. Verschweißung der Dekorschicht mit der Spanholzplatte ohne jegliche Faltenbildung garantieren. Die zu kaschierende Spanholzbahn kann jedoch auch mittels einer Streichvorrichtung vor dem Kaschiervorgang mit einem flüssigen Haftvermittler behandelt werden. Welcher Haftvermittler im Einzelfall eingesetzt wird, ist weitgehend von dem zu kaschierenden Material abhängig.Adhesion promoters in web form are preferably used, for example longitudinally stretched plastic films, because these stretch when heated and thus excellent adhesion or welding of the Guarantee the decorative layer with the chipboard without any wrinkles. The chipboard to be covered however, it can also be applied with a liquid by means of a coating device prior to the lamination process Adhesion promoters are treated. Which adhesion promoter is used in the individual case largely depends on the depending on the material to be laminated.
Gegebenenfalls kann jedoch auch die Dekorschicht bereits mit einem Haftvermittler behandelt sein, um die .Abwickelstellen einzusparen.If necessary, however, the decorative layer can already be treated with an adhesion promoter in order to achieve the .Save unwinding points.
