Abstract
Description
Die Erfindung betrifft eine Vorrichtung und Verfahren zum Transport von Materialbahnen und zum Festlegen derselben auf einer Gegenlage.The The invention relates to an apparatus and method for transportation of material webs and for fixing the same on a counter-surface.
Vorrichtungen
mit diesen Funktionen sind druckschriftlich bekannt. So zeigen die
Die noch unveröffentlichte deutsche Patentanmeldung mit dem Aktenzeichen 103 21 599 zeigt eine andere Wickelvorrichtung, bei der mehrere übereinanderliegende Materialbahnen oder Materialschläuche schon vor Erreichen der letzten Transportwalze des Wicklers mit einer elektrostatischen Ladung versehen werden. Ziel dieser Maßnahme ist die Herbeiführung eines Anhaftverhaltens zwischen diesen Materialbahnen beziehungsweise zwischen der Ober- und der Unterseite des Folienschlauches, welches verhindert, dass die Materialbahnen bei ihrem Transport durch ihren Luftwiderstand voneinander abgehoben werden. Dieses Verfahren ist in allen Arten von Vorrichtungen, in welchen Materialbahnen oder Folienschläuche transportiert werden, vorteilhaft einsetzbar. So werden beispielsweise in Schlauchfolienextrusionsanlagen Folienschläuche über längere Strecken transportiert, wobei ein Abheben der Oberseite von der Unterseite des Schlauches unerwünscht ist.The still unpublished German patent application with the file number 103 21 599 shows another Winding device, in which several superposed material webs or material hoses already before reaching the last transport roller of the winder with a be provided electrostatic charge. The aim of this measure is the induction an adhesion between these webs or between the top and the bottom of the film tube, which prevents the webs of material from being transported through their Air resistance are lifted off each other. This procedure is in all types of devices, in which webs or film tubes be transported, advantageously used. For example transported in tubular film extrusion lines film hoses over long distances, taking a lift off the top of the bottom of the hose undesirable is.
Wenn man das Wort ,Materialbahnen' auch als Oberbegriff zu Folienschläuchen ansieht und unter dem Begriff ,Gegenlage' alle Arten von Auflagemöglichkeiten für Materialbahnen, wie zum Beispiel andere Folienschläuche andere Materialbahnen und Wickelhülsen, zusammenfasst, lassen sich die in den drei Druckschriften dargestellten Maschinen folgendermaßen charakterisieren: Es handelt sich um Vorrichtungen zum Transport von Materialbahnen und zum Festlegen derselben auf einer Gegenlage, wobei die Vorrichtung folgende Merkmale aufweist:
- – zumindest eine Transportwalze zum Transport der Materialbahnen und
- – Mittel zum Beaufschlagen zumindest von Teilen der Materialbahn mit einer elektrostatischen Ladung, deren elektrostatische Kräfte zum Fixieren dieser Teile auf einer Gegenlage beitragen.
- - At least one transport roller for transporting the material webs and
- - Means for applying at least parts of the material web with an electrostatic charge whose electrostatic forces contribute to fixing these parts on a counter-surface.
Alle diese Vorrichtungen lassen Wünsche bezüglich der Zuverlässigkeit des Anhaftverhaltens der Materialbahn auf ihrer Gegenlage offen.All these devices leave you wanting in terms of the reliability the Anhaftverhaltens of the web on its counterclaim open.
Daher besteht die Aufgabe der vorliegenden Erfindung darin, eine Vorrichtung vorzuschlagen, mit der sich das Anhaften der Materialbahn auf ihrer Gegenlage noch zuverlässiger herbeiführen lässt als bisher.Therefore the object of the present invention is a device to propose, with the adhesion of the material web on their Counter even more reliable cause leaves as so far.
Diese Aufgabe wird dadurch gelöst, dass zumindest eine Transportwalze Mittel zum Beaufschlagen zumindest von Teilen der Materialbahn mit einer elektrostatischen Ladung umfasst.These Task is solved by that at least one transport roller means for applying at least of parts of the web comprising an electrostatic charge.
Der Umfang der Verbesserung des Anhaftverhaltens durch die erfindungsgemäße Maßnahme ist überraschend. Offenbar ist der geringere Abstand, den die Materialbahnen zu den Transportwalzen haben, sowie der Umstand, dass sie eben direkten Kontakt zu diesen haben und je nach Umschlingungswinkel und Bahngeschwindigkeit den Kontakt auch eine gewisse Zeit halten können, für diesen Umstand hauptverantwortlich. Bevorzugte Einsatzorte der Erfindung sind Wickelvorrichtungen für Folienmaterial, wobei auch Papierwickler in Frage kommen. Wie erwähnt kann die Erfindung auch in anderen Maschinen, in denen Materialbahnen transportiert werden, eingesetzt werden.Of the Scope of the improvement of the adhesion behavior by the measure according to the invention is surprising. Apparently, the smaller distance that the webs to the Transport rollers have, as well as the fact that they just direct Contact with these and depending on the wrap angle and web speed The contact can also hold a certain time, for this circumstance chiefly responsible. Preferred locations of the invention are winding devices for film material, although paper winder come into question. As mentioned can the invention also in other machines in which webs be transported, are used.
Weitere Ausführungsbeispiele der Erfindung werden anhand der gegenständlichen Beschreibung und der Patentansprüche deutlich.Further embodiments The invention will be apparent from the description and the claims clear.

Zur Bereitstellung einer solchen Schicht kommen vor allem sogenannte elektrisch leitfähige Kunststoffe in Betracht, die in der Regel aus Makromolekülen bestehen, die eine Vielzahl delokalisierbarer Elektronen aufweisen. Diese Elektronen entstammen oft Mehrfachbindungen zwischen den Atomen der Moleküle. Darüber hinaus werden solche Kunststoffe durch die Zugabe (Dotierung) leitfähiger Stoffe wie Metallen oder Graphit leitfähiger gemacht.to Providing such a layer are mainly so-called electrically conductive Plastics, which as a rule consist of macromolecules, which have a multiplicity of delocalizable electrons. These Electrons are often derived from multiple bonds between the atoms of the molecules.
