Abstract

Zur Bildung eines Vlieses aus Stapelfasern werden die Fasern zwischen 2 Saugbänder geworfen. Die Verdichtung erfolgt zwischen den Saugbändern. Funktionswinkel sind einstellbar.To form a fleece from staple fibers, the fibers are thrown between 2 suction belts. The compression takes place between the suction belts. Function angles are adjustable.

Description

In der Textilindustrie gibt es neben dem Herstellen eines Vlieses mittels eines Doffers seit Jahrzehnten die aerodynamische Vliesherstellung. Hierbei werden typischerweise die Fasern von einer letzten Trommel abgesaugt und auf eine Siebtrommel oder ein Siebband angesaugt, z.B. US3906588 . Bei hohen Flächengewichten ist die einseitige Ansaugung an ein Sieb oder an eine Trommel nicht ausreichend. Es werden deshalb 2 Siebtrommeln wie in AT 207674 oder ein Siebband und eine Siebtrommel verwendet. Bei diesen Konstruktionen ist es schwierig, den Abstand, auf den die gebildete Vliesmatte zusammengepresst wird, zu variieren. Bei Kombination von Siebband und Saugtrommel sind die Ansaugspunkte versetzt und die Fasern werden schräg abgelegt. Es entsteht der unerwünschte Schindeleffekt.In the textile industry, in addition to the production of a nonwoven using a doffer, there has been aerodynamic nonwoven production for decades. Here, the fibers are typically sucked off a last drum and sucked onto a sieve drum or a sieve belt, e.g. US3906588 . With high weights per unit area, suction on one side of a sieve or drum is not sufficient. Therefore, 2 screen drums as in AT 207674 or a screen belt and a screen drum are used. With these constructions it is difficult to vary the distance to which the formed nonwoven mat is compressed. When a sieve belt and suction drum are combined, the suction points are offset and the fibers are placed at an angle. The undesirable shingle effect is created.

Aufgabe der Erfindung ist es, ein leicht zu verstellendes Ablagesystem zu schaffen, das den Schindeleffekt vermeidet.The object of the invention is to create an easily adjustable storage system that avoids the shingling effect.

Die Erfindung wird anhand 1 beschrieben. Eine Auflöse- oder Abschlagwalze 1) liefert Fasern/Flocken, die an einem Messer 2) abgeschlagen werden in einen Schacht, der an 2 Seiten durch Siebbänder 3) gebildet wird. Eine Füllhöhenüberwachung 9) verhindert ein Überfüllen des Schachtes und kann die Einfüllmenge beeinflussen. Die herabfallenden Fasern werden durch die umlaufenden Siebbänder 3) verdichtet. Die Ansaugungen 4) verhindern, dass die Fasern an den Siebbändern nicht durchrutschen und Staub austritt. Die Siebbänder können in ihrem Abstand am Auslauf 10) eingestellt werden. Der Winkel α), den die Siebflächen an der Saugseite zur Fasertransportrichtung einnehmen, kann zwischen 0° und 30° betragen. Die Siebbänder bilden 2 Seiten eines parallelen oder in Materiallaufrichtung sich verjüngenden Schachtes. Es ist vorteilhaft, die Umlenkwalzen in einem weiteren Abstand zum Abförderband 8) als die Umlenkwalzen 7) und 11) zu platzieren, um ein Stauchen der abzuführenden Fasermatte zu verhindern. Die Umlenkwalze 7) oder 11), um die die gebildete Fasermatte umgelenkt und von dem Transportband 8) abgeführt wird, sollte einen größeren Abstand vom Abführtransport haben als die anderen der beiden. Die beiden nicht durch Siebbänder gebildeten Seiten des Abführschachtes werden durch keilförmige Wände, vorzugsweise aus durchsichtigem Kunststoff, gebildet. Dadurch entsteht ein Winkel β). Die Bänder können mit einer automatischen Innen- und Außenreinigung versehen sein. Die Bänder werden durch Getriebemotoren vorzugsweise an der oberen Walze 5) angetrieben. Die Bandgeschwindigkeit der Bänder 3) ist maximal 20 % langsamer als die Geschwindigkeit des Bandes 8). Um zusätzlich die Matte zu verdichten, kann sie auch bis zu 100 % schneller sein.The invention is based on 1 described. An opening or chopping roller 1 ) delivers fibers / flakes attached to a knife 2 ) are knocked off in a shaft, which is on 2 sides by sieve belts 3 ) is formed. A level monitoring 9 ) prevents overfilling of the shaft and can influence the filling quantity. The falling fibers are carried by the rotating sieve belts 3 ) compressed. The suction 4th ) prevent the fibers from slipping through the sieve belts and dust from escaping. The sieve belts can be spaced at the outlet 10 ) can be set. The angle α) that the screen surfaces make on the suction side to the fiber transport direction can be between 0 ° and 30 °. The sieve belts form two sides of a chute that is parallel or tapering in the direction of material flow. It is advantageous to place the deflecting rollers at a further distance from the discharge conveyor belt 8th ) than the deflection rollers 7th ) and 11 ) to prevent compression of the fiber mat to be removed. The guide roller 7th ) or 11 ), around which the formed fiber mat is deflected and off the conveyor belt 8th ) should be at a greater distance from the removal transport than the other of the two. The two sides of the discharge chute not formed by sieve belts are formed by wedge-shaped walls, preferably made of transparent plastic. This creates an angle β). The belts can be provided with an automatic internal and external cleaning system. The belts are driven by gear motors, preferably on the top roller 5 ) driven. The belt speed of the belts 3 ) is a maximum of 20% slower than the speed of the belt 8th ). In order to additionally compact the mat, it can also be up to 100% faster.
