Abstract

The carding engine to form a fiber web has a drum to carry the fibers, with a air shaft along it to deliver an air flow downwards from above, to be detached from the drum and fly freely through the air shaft. A jet (10) is in front of the air shaft (4), in the direction of the air flow, with adjustment to set the angle of the air stream against the drum surface. The carding engine, to form a fiber web, has a jet which pivots on an axis which is parallel to the drum axis. Two air channels (8,9) are upstream of the drum (2) which, together, form the air shaft. One channel is a blowing conduit, for the air to be blown, and the other channel (8) is for suction. The jet is located in the blowing channel.

Description

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

Aus der EP 00 93 585 B1 ist eine gattungsbildende Vlieskrempel bekannt. Der Luftschacht dient dort ausschließlich zum Ansaugen von Luft, wobei am unteren Ende des Schachtes eine luftdurchlässige Faserablagefläche vorgesehen ist, beispielsweise ein luftdurchlässiges Transportband, und wobei unterhalb dieser luftdurchlässigen Faserablagefläche ein Sauggebläse vorgesehen ist, welches die Luft durch die Ablagefläche und durch den gesamten Luftschacht am Tambour vorbei ansaugt.From EP 00 93 585 B1 is a generic Vlieskrempel known. The air shaft is used there exclusively for suction of air, wherein at the bottom of the shaft a permeable fiber storage surface is provided, for example an air-permeable conveyor belt, and being below This air-permeable fiber storage surface a suction fan is provided, which the air through the shelf and through the entire air shaft sucking past the drum.

Besonders kritisch ist die Führung der Luft im Bereich der Faserabgabezone, denn in diesem Übergangsbereich, wo sich die Fasern, die zunächst am Tambour anliegen, vom Tambour lösen und dann im freien Flug durch die Luft bis zur Ablagefläche getragen werden sollen, sind Unregelmäßigkeiten in der Luftführung möglichst zu vermeiden, um eine möglichst gleichmäßige Verteilung der Fasern zu ermöglichen und dementsprechend die Herstellung eines möglichst regelmäßig ausgebildeten Vlieses. Particularly critical is the leadership of the air in the area of Fiber delivery zone, because in this transitional area, where the fibers, which initially rest on the drum, from the drum loosen and then in free flight through the air to the storage area are to be borne, are irregularities in the To avoid air flow as much as possible in order to achieve a uniform as possible To allow distribution of the fibers and accordingly the production of a regularly trained Batt.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vlieskrempel dahingehend zu verbessern, dass diese in möglichst kurzer Zeit eine optimale Einstellung der Vlieskrempel in Anpassung an die jeweils spezifischen Arbeitsverhältnisse der Vlieskrempel ermöglicht.The invention is based on the object, a generic Fleece card to improve to the extent that this in as possible short time an optimal adjustment of the fleece card in Adaptation to the specific employment conditions of each Fleece card possible.

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

Die Erfindung schlägt mit anderen Worten vor, die Anströmung der Luft an die Tambour-Oberfläche zu beeinflussen und hierzu eine Düse in Strömungsrichtung vor dem Tambour vorzusehen, sodass die an den Tambour gelangende Luft in ihrer Strömungsrichtung beeinflusst werden kann und insbesondere der Winkel beeinflusst werden kann, unter welchem die Tambour-Oberfläche angeströmt wird.In other words, the invention proposes the flow influence the air to the drum surface and this to provide a nozzle upstream of the spool, so that the air reaching the tambour in its flow direction can be influenced and in particular the angle can be influenced, under which the Tambour surface is flown.

Sowohl bei der Neuinstallation einer gesamten Krempel als auch bei wechselnden Betriebsbedingungen einer Krempel, beispielsweise bei der Verarbeitung unterschiedlicher Fasern oder bei unterschiedlichen Tambourdrehzahlen, ist auf diese Weise eine besonders schnelle Anpassung der Krempel an die jeweiligen Betriebsbedingungen möglich. Insbesondere kann eine Optimierung hinsichtlich der Faserverteilung in möglichst kurzer Zeit dadurch erreicht werden, dass die Düse verstellt wird, sodass der Vorgang optimiert wird, wie sich die Fasern von der Tambour-Oberfläche ablösen, und sodass dementsprechend auch der Flug der Fasern vom Tambour bis auf die Faserablagefläche optimiert und vergleichmäßigt werden kann.Both when reinstalling a whole clutter as well in changing operating conditions of a clutter, for example in the processing of different fibers or at different spool speeds, is this way a particularly fast adaptation of the clutter to the respective Operating conditions possible. In particular, an optimization can in terms of fiber distribution in the shortest possible time be achieved by the nozzle is adjusted so that The process is optimized as the fibers from the tambour surface replace, and so, too the flight of fibers from the spool to the fiber tray surface optimized and evened out.

Falls eine Runddüse vorgesehen ist, sind vorteilhaft über die Tambourbreite mehrere derartige Düsen verteilt angeordnet, um über die gesamte Tambourbreite ähnliche Strömungsverhältnisse zu bewirken. Vorteilhaft jedoch kann statt einer Anordnung mehrerer Runddüsen eine Flachdüse vorgesehen sein, welche sich über etwa die gesamte wirksame Breite des Tambours erstreckt, also über etwa die Breite, auf welcher Fasern auf dem Tambour gefördert werden. So können optimal gleichmäßige Luftströmungsverhältnisse über die gesamte Breite ermöglicht werden, wo die Fasern von der Luftströmung beeinflusst und getragen werden.If a round nozzle is provided, are advantageous over the Tambourbreite several such nozzles arranged distributed to over the entire Tambourbreite similar flow conditions to effect. Advantageously, however, instead of an arrangement several round nozzles a flat nozzle may be provided, which extends over about the entire effective width of the spool, so about about the width on which fibers on the Tambour be promoted. So can be optimally uniform Air flow conditions over the entire width allows where the fibers are influenced and carried by the air flow become.

Vorteilhaft kann die Veränderbarkeit der Düse auf konstruktiv einfache und kostengünstige Weise dadurch erzielt werden, dass nicht die eigentliche Düsengeometrie an sich beeinflusst wird, sondern dass vielmehr die gesamte Düse schwenkbeweglich gelagert ist, sodass der austretende Luftstrahl durch Verschwenken der Düse entsprechend unterschiedlich gelenkt werden kann. Vorteilhaft kann dabei die Schwenkachse der Düse etwa parallel zur Tambour-Achse verlaufen, sodass über die gesamte wirksame Tambourbreite bei einer Verstellung der Düse jeweils gleiche Strömungverhältnisse erzielt werden.Advantageously, the variability of the nozzle on constructive simple and inexpensive way to be achieved by that does not affect the actual nozzle geometry itself but rather that the entire nozzle is pivotable is stored, so that the exiting air jet by pivoting be steered differently according to the nozzle can. Advantageously, the pivot axis of the nozzle approximately parallel to the drum axis, so that over the entire Effective spool width with an adjustment of the nozzle each same flow conditions can be achieved.

Vorteilhaft können zwei Luftkanäle vorgesehen sein, welche in Strömungsrichtung vor dem Tambour gemeinsam den Luftschacht bilden. Dabei handelt es sich um einen Ansaugkanal, der ähnlich wie beim gattungsbildenden Stand der Technik von Luft durchströmt wird, die unterhalb der Faserablagefläche angesaugt wird. Weiterhin handelt es sich um einen Blaskanal, in welchen die Luft von einem zusätzlichen Gebläse eingeblasen wird und der ebenfalls von oben nach unten durchströmt wird. Diese Blasluft unterstützt einerseits die Saugleistung, denn dadurch, dass die Fasern die luftdurchlässige Faserablagefläche teilweise abdecken, muss eine vergleichsweise hohe Ansaugleistung installtiert werden.Advantageously, two air channels can be provided, which in Direction of flow before the drum together the duct form. This is a suction channel, similar to the generic state of the art of Air is flowed through, which sucked in below the fiber storage area becomes. Furthermore, it is a blow channel, in which blown in the air from an additional blower is and is also flowed through from top to bottom. This blowing air on the one hand supports the suction power, because thereby, that the fibers are the air-permeable fiber storage surface partially cover, has a comparatively high intake capacity be installed.

Zudem ist vorteilhaft die veränderbare Düse in dem Blaskanal angeordnet. Durch die Veränderung der Düse und gegebenenfalls durch eine zusätzliche Beeinflussung der Gebläseleistung kann eine Beeinflussung des Blasluftstromes erfolgen und die gesamte Anordnung optimal auf die jeweiligen Betriebsbedingungen der Vlieskrempel eingestellt werden.In addition, the variable nozzle in the blower duct is advantageous arranged. By changing the nozzle and if necessary by an additional influence on the blower output can affect the blowing air flow and the entire arrangement optimally to the respective operating conditions the fleece card will be set.

Ab der Faserabnahmezone kann dann vorteilhaft ein einziger Kanal in Form des Luftschachtes vorgesehen sein, in dem sich die Fasern bewegen.From the fiber removal zone can then advantageously a single Channel be provided in the form of the duct in which move the fibers.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung nachfolgend näher erläutert. Dabei ist mit 1 allgemein und lediglich ausschnittsweise eine Vlieskrempel bezeichnet, mit einem Tambour 2 und mit zwei oberen Cardmastersegmenten 3 und mit einem Luftschacht 4, durch welchen Luft in Richtung der beiden Pfeile P von oben nach unten am Tambour 2 entlang strömt.An embodiment of the invention will be with reference to the drawing explained in more detail below. It is with 1 general and only partially a fleece card called, with a Tambour 2 and with two upper cardmasters segments 3 and with an air shaft 4, through which air in the direction of both arrows P from top to bottom along the drum 2 flows.

Der Tambour dreht sich bei dem dargestellten Ausführungsbeispiel im Uhrzeigersinn und fördert Fasern zwischen der Tambour-Oberfläche und den Cardmastersegmenten 3 in den Luftschacht 4, wo sich in einer Faserabnahmezone die Fasern vom Tambour lösen und durch den Luftschacht 4 nach unten zu einer luftdurchlässigen, nicht dargestellten Faserablagefläche fliegen.The spool turns in the illustrated embodiment in a clockwise direction and promotes fibers between the tambour surface and the Cardmaster segments 3 in the air shaft 4, where in a fiber take-off zone the fibers from Tambour solve and through the air shaft 4 down to a air-permeable, not shown Faserablagefläche fly.

Auf Höhe des Tambours 2 ist der Luftschacht 4 auf der rechten Seite durch eine Schachtwandung 5 begrenzt, die aus zwei gelenkig aneinander anschließenden Schacht-Wandungsabschnitten 5 o (oben) und 5 u (unten) gebildet ist. Die gesamte Schachtwandung 5 kann horizontal verschoben werden, für die Einstellung unterschiedlich weiter Abstände zum Tambour 2. Zusätzlich können die Schacht-Wandungsabschnitte 5 o und 5 u gelenkig verstellt werden, und zwar um einen unteren Schwenkpunkt 6 und einen mittleren Knickpunkt 7. So ergeben sich vielfältige Einstell- und Anpassungsmöglichkeiten, um den Luftschacht 4 in dem Bereich der Faserabnahmezone zu verändern und so die in dieser Zone wirkenden Luftströmungs- und Luftdruckverhältnisse beeinflussen zu können. At the height of the spool 2, the air shaft 4 is on the right Side bounded by a shaft wall 5, consisting of two articulated adjoining manhole wall sections 5 o (top) and 5 u (bottom) is formed. The whole Shaft wall 5 can be moved horizontally, for the Setting different distances to the drum 2. In addition, the shaft wall sections 5 o and 5 u be adjusted articulated, namely to a lower pivot point 6 and a mean break point 7. So arise manifold Adjustment and adjustment options to the air shaft 4 in the region of the fiber take-off zone and so the air flow and air pressure conditions acting in this zone to be able to influence.

In Strömungsrichtung vor dem Tambour 2 besteht der Luftschacht 4 aus zwei unterschiedlichen Kanälen:In the flow direction before the drum 2, the air shaft 4 from two different channels:

Einerseits ist ein Ansaugkanal 8 vorgesehen, in welchen die von unten angesaugte Luft am oberen Ende des Ansaugkanals 8 frei einströmt. Weiterhin wird der Luftschacht 4 in diesem Bereich durch einen Blaskanal 9 gebildet, in welchen Luft von einem oberen, in der Zeichnung nicht dargestellten Gebläse eingeblasen wird. Der Blaskanal 9 endet mit einer Düse 10, die, wie durch den Doppelpfeil angedeutet, schwenkbeweglich gelagert ist und durch welche die Luft aus dem Blaskanal 9 gegen die Tambour-Oberfläche geleitet wird.On the one hand, a suction channel 8 is provided, in which the of sucked down air at the upper end of the intake passage 8 free flows. Furthermore, the air duct 4 in this area formed by a blow channel 9, in which air from a blown above, not shown in the drawing blower becomes. The blower 9 ends with a nozzle 10, which, as indicated by the double arrow, pivotally mounted is and through which the air from the blower 9 against the Tambour surface is passed.

Die Düse 10 ist als Schlitzdüse ausgestaltet und erstreckt sich etwa über die Breite des Tambours 2, um auf der gesamten Breite, auf welcher Fasern vom Tambour 2 abgelöst werden sollen, die Strömungsverhältnisse der Luft zu beeinflussen.The nozzle 10 is configured as a slot nozzle and extends about the width of the spool 2, on the whole Width on which fibers are detached from the drum 2 intended to influence the flow conditions of the air.
