Abstract

Fibers from the card cylinder (3) are deposited in an airflow through a chute (2) on an air-permeable conveyor (11) to form a non-woven. The position of the chute side (4) together with the roller (5) can be adjusted. In addition, the side (7) together with the delivery edge (8) is also adjustable to control the distance for which fibers remain on the cylinder (3) after the last card segment (9). The chute (2) has an airflow splitter (6), which is also adjustable. The conveyor (11) runs in the opposite direction to the airflow and at an angle to it.

Description

Die Erfindung betrifft eine Vlieskrempel nach dem Oberbegriff des Anspruchs 1.The invention relates to a nonwoven card according to the preamble of claim 1.

Aus der Praxis sind derartige Vlieskrempel bekannt, siehe z.B DE 202 05 954 U . Dabei ist es bekannt, durch Verstellungen im Bereich des Luftschachtes, sei es durch eine Wandung des Luftschachtes oder sei es durch die Verstellung von einer im Luftschacht vorgesehenen Düse bzw. von einem im Luftschacht vorgesehenen Luftteiler den Luftstrom derart zu beeinflussen, dass hierdurch der Faserstrahl gelenkt werden kann bzw. der Ablösungsvorgang der Fasern vom Tambour sowie die Ablage der Fasern auf dem Ablageband beeinflusst werden kann.From the practice of such fleece cards are known, see, for example DE 202 05 954 U , It is known, through adjustments in the air duct, be it by a wall of the duct or be it by the adjustment of a nozzle provided in the duct or by an air duct provided in the air divider to influence the air flow such that thereby directs the fiber jet can be influenced or the detachment process of the fibers from the drum as well as the filing of the fibers on the storage belt.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vlieskrempel dahingehend zu verbessern, dass eine möglichst vielseitige und effektive Beeinflussung des Luftstrahls möglich ist.The invention has for its object to improve a generic Vlieskrempel to the effect that the most versatile and effective influencing of the air jet is possible.

Diese Aufgabe wird durch eine Vlieskrempel mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a fleece card with the features of claim 1.

Die Erfindung schlägt mit anderen Worten vor, nicht nur eine sondern beide Wandungen des Luftschachtes zu verstellen. So können beispielsweise beide Wandungen um eine Achse verschwenkt werden, die parallel zur Achse des Tambours verläuft, oder die beiden Wandungen können parallel gemeinsam bewegt werden, so dass der Luftschacht quasi gegenüber dem Tambour verschoben wird und das tangentiale Auftreffen der Luft auf den Tambour auf diese Weise beeinflusst wird, so dass insbesondere der Bereich, in welchem die Fasern vom Tambour abgeschleudert werden, beeinflussbar ist und auf diese Weise der weitere Faserverlauf bis auf das Ablageband beeinflusst werden kann.In other words, the invention proposes to adjust not only one but both walls of the air shaft. Thus, for example, both walls can be pivoted about an axis which is parallel to the axis of the main cylinder, or the two walls can be moved together in parallel, so that the air duct is moved virtually opposite to the spool and the tangential impingement of the air on the spool on this Way is influenced, so that in particular the area in which the fibers are thrown off the spool, can be influenced and in this way the further fiber flow can be influenced up to the storage belt.

Ein Ausführungsbeispiel der Erfindung wird anhand der rein schematischen Zeichnung nachfolgend näher erläutert.An embodiment of the invention will be explained in more detail below with reference to the purely schematic drawing.

Bei einer Krempel 1 ist ein einstellbarer Luftschacht 2 vorgesehen, welcher Luft tangential an einen Tambour 3 führt und durch zwei Wandungen begrenzt wird. Eine tambourferne Wandung 4 des Luftschachtes 2 ist, wie durch den Doppelpfeil in der Zeichnung angedeutet, gemeinsam mit einer unteren Walze 5 seitlich verstellbar. Innerhalb des Luftschachtes 2 befindet sich kurz bevor die Luft den Tambour 3 erreicht ein Luftteiler 6.In a carding 1, an adjustable air duct 2 is provided, which leads tangentially air to a spool 3 and is bounded by two walls. A tambourferne wall 4 of the air shaft 2 is, as indicated by the double arrow in the drawing, together with a lower roller 5 laterally adjustable. Within the air shaft 2 is located just before the air reaches the drum 3, an air divider. 6

Die tambournahe Wand 7 des Luftschachtes 2 ist gemeinsam mit einer Abschleudernase 8 ebenfalls seitlich verstellbar, wie ebenfalls durch einen Doppelpfeils angedeutet. Durch die Verstellbarkeit der Abschleudernase wird der Faserstrahl von Textilfasern, die auf dem Tambour im Spalt zwischen der Tambouroberfläche und dem dargestellten Kardiersegment 9 sowie ggf. vorhandenen, nicht dargestellten Kardiersegmenten gefördert werden, so beeinflusst, dass die Fasern entweder noch länger am Tambour anliegen, nachdem sie die Abschleudernase 8 passiert haben, oder dass der Faserstrahl weiter entfernt davon fliegt, so dass der Ablösepunkt an welchem die Fasern den Tambour verlassen, beeinflusst werden kann.The tambournahe wall 7 of the air shaft 2 is also adjustable laterally together with a skimmer 8, as also indicated by a double arrow. Due to the adjustability of the haul-off nose, the fiber jet of textile fibers, which are conveyed on the spool in the gap between the spool surface and the illustrated carding segment 9 and possibly existing carding segments (not shown), is influenced so that the fibers either rest even longer on the spool, after they have passed the haul-off nose 8, or that the fiber jet is farther away from it flies, so that the separation point at which the fibers leave the tambour can be influenced.

Die Ablösung beginnt grundsätzlich bereits am Ende des Kardiersegmentes 9, also wenn die Fasern am rechts dargestellten Ende des Kardiersegmentes 9 angelangt sind. Dort beginnt ein Abschleuderkanal 10, der sich bis zur Abschleudernase 8 erstreckt. Das entsprechende Ende des Kardiersegmentes 9 ist mit A gekennzeichnet, wobei dies den Abschleuderpunkt bezeichnet.The detachment generally begins at the end of the carding segment 9, ie when the fibers have arrived at the end of the carding segment 9 shown on the right. There begins a Abschleuderkanal 10, which extends to the skimmer nose 8. The corresponding end of the carding segment 9 is marked A, which denotes the Abschleuderpunkt.

Der Luftteiler 6 ist gemeinsam mit der Abschleudernase und der tambournahen Wand 7 des Luftschachtes 2 verstellbar.The air divider 6 is adjustable together with the Abschleudernase and the tambournahen wall 7 of the air shaft 2.

Die Fasern werden gleichmäßiger verteilt auf einem luftdurchlässigen Ablageband 11 abgelegt, wenn das Band entgegen der Richtung des Luftstroms verläuft, also in Richtung des rechts am Ablageband 11 angedeuteten Pfeils.The fibers are deposited evenly distributed on an air-permeable storage belt 11 when the tape runs counter to the direction of the air flow, ie in the direction of the arrow indicated on the right on the storage belt 11.

Die Schrägstellung des Ablagebandes 11 dort, wo der Faserstrahl auf das Ablageband 11 auftritt, also der Winkel zwischen Ablageband 11 und Faserstrahl, kann durch eine verstellbare Umlenkrolle 12 beeinflusst werden, wobei gemeinsam mit der Umlenkrolle 12 auch ein Abdichtungsbauteil 14 verstellt werden kann, damit dies möglichst eng an dem Ablageband 11 geführt ist.The inclination of the storage belt 11 where the fiber jet occurs on the storage belt 11, so the angle between storage belt 11 and the fiber jet, can be influenced by an adjustable guide roller 12, wherein together with the guide roller 12, a sealing member 14 can be adjusted so this as close as possible to the storage belt 11 is guided.

Unterhalb des Ablagebandes 11 erstreckt sich in an sich bekannter Weise ein Saugkanal 15.Below the storage belt 11 extends in a conventional manner, a suction channel 15th
