Abstract
Description
Die Erfindung betrifft einen Querschneider für eine kontinuierlich zugeführte Papierbahn gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a cross cutter for a continuously fed paper web according to the generic term of claim 1.
Solches imprägniertes Papier ist z.B. einseitig bedruckt und mit einem Gemisch aus Melaminharz und Korund beschichtet. Das fertige Papier kann aus mehreren Lagen bestehen, die durch das Harz miteinander verbunden sind. Es wird unter anderem für die Herstellung von Fußbodenbelägen als Dekorschicht benutzt, wobei der Korund eine harte, verschleißfeste Beschichtung darstellt.Such impregnated Paper is e.g. printed on one side and with a mixture of melamine resin and corundum coated. The finished paper can consist of several layers exist, which are interconnected by the resin. It will for, among other the production of floor coverings as Decorative layer used, wherein the corundum a hard, wear-resistant coating represents.
Querschneider werden z.B. in der Papierveredelung eingesetzt, um imprägnierte und/oder beschichtete Papierbahnen in zumindest annähernd rechtwinklige Bogen zu schneiden. Hierfür sind beispielsweise als mechanische Vorrichtungen sogenannte Rotationsquerschneider bekannt, bei denen Messer auf zwei drehbaren Walzen montiert sind, zwischen denen die Papierbahn transportiert wird. Wenn ein Schnitt erfolgen soll, werden die Walzen angetrieben, so dass die Papierbahn von den Messern senkrecht zur Bahnlaufrichtung durchtrennt wird. Nachteil der mechanischen Querschneider ist, dass bei korundhaltigen Beschichtungen die Messer sehr schnell verschleißen und entsprechend häufig ausgetauscht werden müssen. Dies führt zu Stillstandszeiten für den Austausch der Messer und zu hohen Materialkosten. Gehärtete Messer oder solche aus Hartmetall sind teuer und bringen keine wesentlichen Verbesserungen.Sheeter are used e.g. used in paper finishing to impregnate and / or coated paper webs in at least approximately rectangular To cut bow. Therefor are, for example, as mechanical devices so-called rotary cross cutter known in which knives are mounted on two rotatable rollers between where the paper web is transported. If a cut done should, the rollers are driven so that the paper web of the knives is severed perpendicular to the web running direction. disadvantage The mechanical sheeter is that with corundum coatings The blades wear out very quickly and replaced frequently Need to become. this leads to at downtime for the replacement of the knives and high material costs. Hardened knives or those made of carbide are expensive and bring no significant Improvements.
Aus
der
Aufgabe der Erfindung ist es, einen Querschneider für mit abriebfestes Material enthaltendem Harz beschichtete Papierbahnen zu schaffen, der einen sicheren Schnitt gewährleistet und lange Standzeiten aufweist.task The invention is a cross cutter for abrasion resistant material containing resin-coated paper webs to provide a guaranteed safe cutting and has long lifetimes.
Die Aufgabe ist durch Anspruch 1 gelöst. Die fehlende Unterstützung der Papierbahn im Bereich des Schnitts bewirkt, dass der Laserstrahl die Papierbahn sicher durchtrennen kann, ohne dass hierbei Teile des Querschneiders in den schneidenden Bereich des La serstrahls gelangen. Dies verlängert einerseits die Standzeit es Querschneiders und verhindert andererseits, dass zusätzliche Dämpfe entstehen und die Qualität der Papierbahn beeinträchtigen können. Die Absaugung oberhalb und unterhalb der Papierbahn bewirkt, dass die beim Laserschneiden entstehenden Dämpfe schnell und vollständig abgeführt werden und dann entsorgt werden können. Dies ist besonders wichtig, weil die Papierbahn auch nennenswerte Anteile an Harzen und an abriebfestem Material wie z.B. Korund und/oder Silicium enthält.The The object is solved by claim 1. The lack of support the paper web in the area of the cut causes the laser beam can safely cut through the paper web, without this parts of the cross cutter into the cutting area of the laser beam reach. This is extended on the one hand, the life of it cross cutter and on the other hand prevents that extra fumes emerge and the quality can affect the paper web. The Extraction above and below the paper web causes the During laser cutting vapors are dissipated quickly and completely and then be disposed of. This is especially important because the paper web is also worth mentioning Proportions of resins and abrasion resistant material, e.g. Corundum and / or Contains silicon.
Die Unteransprüche betreffen die vorteilhafte Ausgestaltung der Erfindung.The under claims relate to the advantageous embodiment of the invention.
Die Ausbildung der unteren Mittel zum Absaugen als Strahlenfalle verhindert, dass schädliche Laserstrahlen aus dem Querschneider austreten können.The Forming the lower means of suction as a radiation trap prevents that harmful laser beams can emerge from the sheeter.
Die Verfahrbarkeit der Mittel zum Umlenken des Strahls in einem Tragarm in deren Längsrichtung, wobei der Tragarm sich im wesentlichen über die Breite der Papierbahn erstreckt und mit einer Bahnlaufrichtung der Papierbahn einen Winkel α einschließt, erlaubt eine präzise Schnittführung.The Movability of the means for deflecting the beam in a support arm in the longitudinal direction, wherein the support arm substantially over the width of the paper web extends and encloses an angle α with a web running direction of the paper web allowed a precise one Cut.
Ein Saugrohr, das mit den Mitteln zum Umlenken verfahrbar ist, erlaubt eine sichere Absaugung der Dämpfe bei minimaler Saugluftmenge.One Suction tube, which is movable with the means for deflecting allowed a safe extraction of vapors with minimal amount of suction air.
Laser bis 750 Watt sind preisgünstig erhältlich.laser up to 750 watts are inexpensive available.
Ein zusätzlicher mechanischer Querschneider erlaubt die einfache Herstellung von Probebögen, die ein kleineres Format aufweisen als die üblichen Bögen und nur in vorwählbaren zeitlichen Abständen hergestellt werden.One additional mechanical cross cutter allows easy production of Test sheets, which have a smaller format than the usual bows and only in preselected time intervals getting produced.
