Abstract

The non-woven fabric manufacturing machine has a web unit that is provided with several set of rollers, and output ends of feed chutes (1,2) that are arranged above the axes of end main roller (4). Air sucked through a screen belt or drum screen that is arranged on the sides of several rollers, is guided along the surfaces of the rollers. An independent claim is included for method for manufacturing non-woven fabric.

Description

Seit 1775 gibt es Karden zur Bildung eines Faservlieses. Alle diese Maschinen weisen eine Zuführvorrichtung für eine Fasermatte, mindestens eine Walze, auf, die die Fasermatte mittels Stiften oder Haken auflöst, und eine Vorrichtung zum Abfördern der Fasern von der letzten Auflösetrommel und zur Bildung eines Vlieses.Since 1775 there are cards to form a fiber fleece. All of these machines include a fiber mat feeding device, at least one roller that disintegrates the fiber mat by means of pins or hooks, and a device for removing the fibers from the last disintegrating drum and forming a nonwoven web.

Alle diese Maschinen gehen von einem horizontal orientierten Faserdurchlauf aus, d. h. die Fasermatte wird auf einer Höhe von 0,5 bis 1 m über der Aufstellebene zugeführt, die Auflösewalzen fördern die Fasern zum Teil höher als den Einlauf und das Vlies verlässt die Maschine etwas über der Höhe des Einlaufs. Diese horizontale Anordnung hat Nachteile. Da die Maschinen bis zu 5 m Arbeitsbreite haben, ist die Zugänglichkeit der Maschinen nur an den Seiten der Maschinen gegeben. Es ist deshalb notwendig, die Maschinen auseinander fahrbar zu bauen; dies ist sehr aufwändig. Da viele Anlagen aus mehreren Vliesbildemaschinen bestehen, die auf ein gemeinsames Transportsystem die Vliese ablegen, werden diese Anlagen sehr lang unübersichtlich und durch die Unterbauten teuer. Bei Vliesbildemaschinen ist in die Maschine ein System von Absaugleitungen integriert, um insbesondere an den Enden der Walzen unerwünscht herumfliegende Fasern abzusaugen. Ein solches Rohrsystem wird aus polierten Aluminiumrohren gefertigt und ist in der Anschaffung teuer und durch die hohen Widerstände durch die Verästelungen energieaufwändig. Bei Vliesbildemaschinen mit aerodynamischer Vliesbildung wird Umgebungsluft entlang der letzten Walze gesaugt, die die Fasern mitnimmt und auf einer Siebtrommel oder einem luftdurchlässigen Band ablegt. Um die Abnahme der Fasern zu verbessern, wird die Umgebungsluft zusätzlich zu der Absaugung mit einem Querstromgebläse beschleunigt. Dies ist sehr energieaufwändig.All of these machines are based on a horizontally oriented fiber pass, i. H. the fiber mat is supplied at a height of 0.5 to 1 m above the setting level, the opening rollers convey the fibers partly higher than the inlet and the mat leaves the machine slightly above the height of the inlet. This horizontal arrangement has disadvantages. As the machines have a working width of up to 5 m, the accessibility of the machines is only given on the sides of the machines. It is therefore necessary to make the machines mobile apart; this is very expensive. Since many systems consist of several web forming machines, which store the nonwovens on a common transport system, these systems are very long confusing and expensive by the substructures. In web forming machines, a system of suction lines is integrated into the machine in order to suck off unwanted flying fibers, especially at the ends of the rolls. Such a pipe system is made of polished aluminum pipes and is expensive to purchase and energy-intensive due to the high resistance through the branches. In web-forming machines with aerodynamic web formation, ambient air is sucked along the last roller, which entrains the fibers and deposits them on a screen drum or an air-permeable belt. In order to improve the decrease of the fibers, the ambient air is accelerated in addition to the suction with a cross-flow fan. This is very energy consuming.

Aufgabe der Erfindung ist es, eine kompakte, gut zugängliche Vliesbildemaschine zu schaffen, die eine einfache und günstige Faserabsaugung beinhaltet.The object of the invention is to provide a compact, easily accessible web forming machine, which includes a simple and cheap fiber extraction.

In der US-48132104 hat die Fa. Hollingsworth eine kompakte Karde vorgeschlagen, bei der der Dofferzylinder über dem Hauptzylinder angeordnet war. Es ist jedoch deutlich zu erkennen, dass der Chute Feed die Zugänglichkeit behindert und die Absaugrohre aufwändig sind. Diese Anmeldung betrifft jedoch keine Vliesmaschine für die Non Wovens-Industrie, sondern eine Maschine zum Herstellen eines Faserbandes für die Spinnerei.In the US-48132104 Hollingsworth has proposed a compact card with the doffing cylinder over the master cylinder. However, it can be clearly seen that the chute feed hinders accessibility and the suction tubes are expensive. However, this application does not relate to a nonwoven machine for the nonwovens industry but to a machine for making a sliver for spinning.

Die vorliegende Erfindung betrifft eine Maschine zur aerodynamischen Bildung eines Vlieses. Hier wird die Aufgabe gelöst, indem alle faserführenden Walzen übereinander angeordnet sind, der Ausgang des Chute Feeds über den Hauptzylindern mündet und die Luft zur aerodynamischen Vliesbildung von oben nach unten entlang aller Hauptwalzen geführt wird.The present invention relates to a machine for the aerodynamic formation of a nonwoven. Here, the object is achieved by all fiber-guiding rollers are arranged one above the other, the output of the chute feed opens on the main cylinders and the air for aerodynamic web formation is guided from top to bottom along all main rollers.

Die Erfindung wird anhand 1 erläutert. Die Fasern gelangen über einen Zuführschacht 1) in den Chute Feed 2), wo an Siebflächen die Fasermatte gebildet wird. Eine Einzugswalze 3) zieht die Fasermatte aus dem Chute Feed ab und übergibt sie an die Hauptwalzen 4). An Kardierelementen 6) werden die Fasern geöffnet und von der letzten Hauptwalze durch den Luftstrom und eine Aushebemesser 5) entfernt. Das Vlies wird durch Ansaugung auf dem Transportband 7) gebildet, das um Umlenkwalzen 8) bewegt wird. Die Luft gelangt durch Zuluftöffnungen 11) oben in die Maschine und streicht entlang der Walzen, bevor sie die Fasern abnimmt und auf dem Siebbband 7) ablegt. Die Luft wird durch das Siebband 7) hindurchgesaugt, im Ansaugkasten 9) gesammelt und durch ein Ansaugrohr 10) zum Saugventilator geleitet. Die Walzen sind teilweise mit Abdeckblechen 12) versehen.The invention is based on 1 explained. The fibers pass through a feed chute 1 ) in the chute feed 2 ), where at Siebflächen the fiber mat is formed. A feed roller 3 ) pulls the fiber mat from the chute feed and passes it to the main rollers four ). At carding elements 6 ), the fibers are opened and from the last main roll by the air flow and a Aushebemesser 5 ) away. The fleece is made by suction on the conveyor belt 7 ) formed around deflection rollers 8th ) is moved. The air passes through supply air openings 11 ) into the top of the machine and sweep along the rollers before removing the fibers and on the belt 7 ). The air passes through the sieve belt 7 sucked through, in the intake box 9 ) and through a suction pipe 10 ) to the suction fan. The rollers are partially with cover plates 12 ) Mistake.

Durch die übereinander angeordneten Walzen ist eine gute Zugänglichkeit zu allen Elementen (Walzen, Kardiersegmenten) gegeben. Der Luftzug von oben nach unten erübrigt ein Absaugsystem. Die Maschine bleibt fusselfrei, und der Luftverbrauch und Energieverbrauch werden deutlich reduziert. Die Maschine baut äußerst kompakt.Due to the superposed rollers, good accessibility to all elements (rollers, carding segments) is given. The draft from top to bottom eliminates the need for an exhaust system. The machine remains lint-free and air consumption and energy consumption are significantly reduced. The machine is extremely compact.
