Abstract
Description
Es ist ein Verfahren zum Betreiben einer Vorrichtung zum Legen eines Vlieses aus endlichen Fasern nach dem Luftlegeverfahren bekannt, wobei die Vorrichtung aus einer drehbar gelagerten Legetrommel besteht, deren Mantel für die Fasern durchlässig ist. Die Legetrommel wird von einem Luftstrom radial in Richtung eines das zu legende Vlies tragenden, entlang der Legetrommel vorwärts laufenden Endlosbandes durchströmt, wobei die zu einem Vlies zu fegenden Fasern stirnseitig in Achsrichtung der Legetrommel zugeführt werden.It is a method of operating a device for laying a fleece of finite fibers known the air laying process, the device from a rotatable stored laying drum, the jacket of which is permeable to the fibers. The laying drum is driven radially in the direction of an air stream carrying the fleece to be laid, running forward along the laying drum Flows through endless belt, the fibers to be swept into a fleece face in the axial direction fed to the laying drum become.
Die Zuführung der Pulpfasern erfolgt nach diesem Stand der Technik im Bereich des Außendurchmessers der Legetrommel, also exzentrisch. Innerhalb der Legetrommel ist eine Kammtrommel, deren Kämme die Mantelfläche der Legetrommel nur entlang einer Linie berühren, ebenfalls exzentrisch gelagert. Dieser Legetrommel ist parallel eine zweite Trommel zugeordnet, die über Rohre miteinander verbunden sind, die ebenfalls an den Stirnseiten angreifen. Eine Legeeinrichtung besteht also aus zwei Legetrommeln, zwischen denen Fasern im Kreislauf fließen.The pulp fibers are fed according to this state of the art in the area of the outer diameter of the laying drum, so eccentric. Inside the laying drum is a comb drum, their combs the lateral surface touch the laying drum only along a line, also mounted eccentrically. A parallel drum is assigned to this laying drum, the above Pipes are connected to each other, which are also on the end faces attack. A laying device therefore consists of two laying drums, between which fibers flow in a cycle.
Die Legetrommeln erstrecken sich über die ganze Arbeitsbreite, die bis zu 4 oder 5 m reichen kann. Um eine gleichmäßige Verteilung der Fasern auf dem Endlosband zu erzielen, müssen die Trommeln einen entsprechenden Durchmesser aufweisen. Dieser ist aber beschränkt durch die erforderlichen Ausmaße der Kugellager, die zur drehbaren Lagerung der Legetrommel an ihrem Außendurchmesser angeordnet sind. Grund dafür sind die notwendigen exzentrischen Öffnungen in den Stirnseiten der Legetrommeln. Die Kugellager können in ihrem Durchmesser nun nicht in jeder beliebigen Größe gebaut werden. Bei einer höheren Drehzahl – wie das hier beim Betrieb der Legetrommeln notwendig ist – laufen die Kugeln der Kugellager bei zu großen Durchmessern, die über einem Meter liegen, in den Lagerschalen zu schnell, so dass der Schmierfilm abreißt.The laying drums extend over the whole Working width that can reach up to 4 or 5 m. For an even distribution To achieve the fibers on the endless belt, the drums must have an appropriate one Have diameter. However, this is limited by the required dimensions the ball bearing, which is used for the rotatable mounting of the laying drum on your outer diameter are arranged. the reason for this are the necessary eccentric openings in the end faces the laying drums. The ball bearings can now in their diameter not built in any size become. At a higher one Speed - like that is necessary here when operating the laying drums - run the balls of the ball bearings if the diameters are too large, Meters lie in the bearing shells too quickly, so the lubricating film interrupted.
Der Erfindung liegt die Aufgabe zugrunde, eine Lösung für das Problem zu finden. Die Legetrommeln sollen in jedem gewünschten Durchmesser hergestellt werden können, der sich nämlich aus der jeweiligen Breite des zu legenden Vlieses ergibt. Außerdem ist ein größerer Durchmesser der Legetrommeln für die Produktionsgeschwindigkeit des zu legenden Vlieses von Vorteil.The invention has for its object a solution for the Finding problem. The laying drums should be in any desired Diameter can be produced which is namely results from the respective width of the fleece to be laid. Besides, is a larger diameter of the laying drums for the production speed of the fleece to be laid is an advantage.
Ausgehend von dem Verfahren anfangs genannter Art ist die Lösung darin gefunden, dass die Fasern zentrisch in die Legetrommel geführt werden. Mit Vorteil werden die Fasern beiden Stirnseiten der Legetrommel zentrisch zugeführt.Starting from the procedure initially the type mentioned is the solution found that the fibers are guided centrally into the laying drum. With The fibers are advantageously centered on both ends of the laying drum fed.
Die Vorrichtung zum Legen eines Vlieses aus endlichen Fasern wie auch Pulpfasern nach dem Luftlegeverfahren ist mit einer in einem Gehäuse drehbar gelagerten durchlässigen Legetrommel mit einer stirnseitigen Öffnung zur Zuführung der Fasern versehen, wobei die Legetrommel oberhalb eines das zu legende Vlies tragenden Endlosbandes angeordnet ist, dem unterhalb ein Saugkasten zum Absaugen des der Legetrommel radial oberhalb zugeführten Luft zugeordnet ist. Nach der Erfindung ist nunmehr die stirnseitige Öffnung zur Zuführung der Fasern in die Legetrommel zentrisch angeordnet ist. Es ist damit die Achse der Legetrommel als Faserzuführrohr ausgebildet, das nur einen so großen Durchmesser aufweisen muss, dass die notwendige Menge an Fasern einbringbar ist. Damit ist der Durchmesser der notwendigen Kugellager zur drehbaren Lagerung der Legetrommel völlig unabhängig vom Außendurchmesser der Legetrommel. Die Legetrommeln können in jedem beliebigem Ausmaß gebaut werden, die Kugellager werden auch bei hoher Umfangsgeschwindigkeit nie heiß laufen.The device for laying a fleece finite fibers as well as pulp fibers according to the air laying process can be rotated with one in a housing stored permeable Laying drum with an opening at the front for feeding the Fibers provided, the laying drum above the one to be laid Fleece-carrying endless belt is arranged, below which a suction box for extracting the air supplied to the laying drum radially above assigned. According to the invention, the front opening is now for feed the fibers are arranged centrally in the laying drum. It is with it the axis of the laying drum is designed as a fiber feed tube, that only such a big one Diameter must have the necessary amount of fibers can be introduced. This is the diameter of the necessary ball bearings for the rotatable mounting of the laying drum completely independent of the outside diameter of the laying drum. The laying drums can built to any extent the ball bearings are also at high peripheral speed never run hot.
In der Legetrommel ist eine Kammtrommel zu lagern, deren Kämme von der Innenseite am Mantel der Legetrommel reiben und die Fasern durch die Öffnungen des Mantel fördern. Diese Kammtrommel wird ebenfalls zentrisch in der Legetrommel gelagert, und zwar bildet diese Kammtrommel in der Achse die Faser-Einführöffnung und um das entsprechende Einführrohr ist dann das Lager der Legetrommel angeordnet.A comb drum is closed in the laying drum store their combs from the inside rub against the jacket of the laying drum and the fibers through the openings promote the coat. This comb drum is also stored centrally in the laying drum, and this comb drum forms the axis of the fiber insertion opening and around the corresponding insertion tube then the bearing of the laying drum is arranged.
