Description
Die Erfindung betrifft eine Galetteneinheit zum Führen eines multifilen Fadens gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a godet unit for guiding a multifilament yarn according to the preamble of
Eine gattungsgemäße Galetteneinheit ist aus der
Die bekannte Galetteneinheit weist eine Galette und eine in der Galette zugeordnete Beilaufrolle auf, um einen Faden mit einer Mehrfachumschlingung zu führen. Zwischen der Galette und der Beilaufrolle ist eine Verwirbelungseinrichtung angeordnet. Die Verwirbelungseinrichtung ist eine zwischen der Galette und der Beilaufrolle gespannten Fadenstück zugeordnet, um an dem laufenden Faden eine Verwirbelung zu erzeugen. Bei dem Verwirbeln, das auch unter der Bezeichnung Tangeln bekannt ist, wird ein Druckluftstrom auf den Faden gerichtet, so dass eine Verschlingung der einzelnen Filamente des Fadens entsteht und somit ein Fadenschluss an dem Faden hergestellt wird. Dabei bilden sich je nach Intensität der Druckluft mehr oder weniger ausgeprägte Verwirbelungsknoten aus, die in regelmäßigen Abständen den Fadenschluss des Fadens für eine Weiterbearbeitung erzeugen. Hierbei wird eine Mindestanzahl an Knoten pro Längeneinheit des Fadens gewünscht, um ein Aufspreizen des Filamentbündels bei der Weiterverarbeitung zu vermeiden. Insbesondere bei Fäden, die eine endgültigen Weiterverarbeitung zugeführt werden, wie beispielsweise Teppichgarne ist eine hohe Gleichmäßigkeit und eine relativ hohe Anzahl der Verflechtungsknoten pro Fadenmenge gewünscht.The known godet unit has a galette and a godet roller associated with the galette in order to guide a thread with a multiple loop. Between the galette and the auxiliary role, a swirling device is arranged. The swirling device is associated with a tensioned between the godet and the fan roller piece of thread to create a swirling on the current thread. In the swirling, which is also known as tangling, a stream of compressed air is directed onto the thread, so that an entanglement of the individual filaments of the thread is formed and thus a thread closure is made on the thread. Depending on the intensity of the compressed air, more or less pronounced turbulence nodes are formed, which at regular intervals produce the thread closing of the thread for further processing. In this case, a minimum number of knots per unit length of the thread is desired in order to avoid spreading of the filament bundle during further processing. In particular, in the case of yarns which are subjected to a final further processing, such as carpet yarns, a high degree of uniformity and a relatively high number of interlacing knots per yarn amount is desired.
Bei der bekannten Vorrichtung wird eine stationäre Verwirbelungseinrichtung verwendet, bei welcher der Faden nach Ablauf von der Galette durch einen Behandlungskanal der Verwirbelungseinrichtung geführt wird, in welcher eine Düsenbohrung mit einem Luftstrom mündet. Derartige stationäre Vorrichtungen haben den Nachteil, dass bei höheren Fadengeschwindigkeiten Lücken ohne Verflechtungsknoten bzw. unzureichende Anzahl von Verflechtungsknoten in dem Faden erzeugt werden. Desweiteren behindert eine in einer Galetteneinheit integrierte Verwirbelungseinrichtung, die üblicherweise zwischen einer Galette und einer Beilaufrolle oder zwischen zwei Galetten angeordnet ist, den Fadenlauf der benachbarten Fadenumschlingungen. Insoweit müssen Mindestabstände zwischen den Fadenumschlingungen in der Galetteneinheit eingehalten werden, um durch die aus der Verwirbelungseinrichtung austretenden Luft benachbarter Fadenläufe nicht zu behindern.In the known device, a stationary swirling device is used, in which the thread is guided after the expiry of the galette through a treatment channel of the swirling device, in which a nozzle bore opens with an air flow. Such stationary devices have the disadvantage that at higher yarn speeds Gaps without merge nodes or insufficient number of merge nodes are generated in the thread. Furthermore, an integrated in a godet unit Verwirbelungseinrichtung, which is usually arranged between a godet and a flywheel or between two godets hinders the threadline of the adjacent Fadenumschlingungen. In that regard, minimum distances between the thread wraps must be maintained in the godet unit, so as not to hinder by the air emerging from the vortexing device adjacent threadlines.
Es ist nun Aufgabe der Erfindung, die gattungsgemäße Galetteneinheit zum Führen eines multifilen Fadens derart auszubilden, dass benachbarte Umschlingungen des Fadens an der Galetteneinheit selbst bei relativ dichten Fadenabständen von der Verwirbelungseinrichtung nicht beeinträchtigt werden.It is an object of the invention to form the generic godet unit for guiding a multifilament yarn such that adjacent wraps of the thread to the godet unit are not affected even at relatively dense thread pitches of the turbulator.
Ein weiteres Ziel der Erfindung liegt darin, eine Galetteneinheit mit einer Verwirbelungseinrichtung bereitzustellen, die auch bei Fadengeschwindigkeiten oberhalb von 3.000 m/min. eine ausreichende Anzahl von Verflechtungsknoten erzeugt.Another object of the invention is to provide a godet unit with a swirling device, which is also at yarn speeds above 3,000 m / min. generates a sufficient number of merge nodes.
Diese Aufgabe wird erfindungsgemäß für eine Galetteneinheit dadurch gelöst, dass die Verwirbelungseinrichtung unmittelbar der Galette zugeordnet ist und mit der Galette ein Kombinationsaggregat bildet.This object is achieved according to the invention for a godet unit in that the swirling device is assigned directly to the godet and forms a combination aggregate with the godet.
Vorteilhafte Weiterbildungen der Erfindung sind durch die Merkmale und Merkmalskombinationen der jeweiligen Unteransprüche definiert.Advantageous developments of the invention are defined by the features and feature combinations of the respective subclaims.
Die Erfindung zeichnet sich dadurch aus, dass der Zwischenraum zwischen der Galette und der Beilaufrolle frei zur Führung des Fadens genutzt werden kann. Die Verwirbelungseinrichtung ist unmittelbar in der Galette integriert, so dass der Faden bei Auflauf oder bei Ablauf von der Galette eine Luftbehandlung durch die Verwirbelungseinrichtung erhält.The invention is characterized in that the space between the godet and the battress roller can be freely used to guide the thread. The swirling device is directly in the Galette integrates, so that the thread receives an air treatment by the swirling device at casserole or at the end of the galette.
Das derart gebildete Kombinationsaggregat weist gemäß einer vorteilhaften Weiterbildung der Erfindung bevorzugt einen drehend angetriebenen Führungsmantel mit mehreren axial hintereinander liegenden Führungsabschnitten auf, wobei an einem der Führungsabschnitte des Führungsmantels eine umlaufende Führungsnut mit zumindest einer den Führungsmantel durchdringenden Düsenbohrung ausgebildet ist und wobei dem Führungsabschnitt im Innern des Führungsmantels eine Druckluftzuführeinrichtung zugeordnet ist. Damit lässt sich der Faden ohne zusätzliche Hilfsführungsmittel vorteilhaft in mehreren Umschlingungen an den Führungsmantel des Kombinationsaggregates führen. In einem der Führungsabschnitte wird der Faden in der Führungsnut geführt, in welcher in einer Winkellage des Führungsmantels eine Luftbehandlung an dem Faden zur Erzeugung von Verflechtungsknoten ausführbar ist.According to an advantageous development of the invention, the combination unit formed in this way preferably has a rotationally driven guide casing with a plurality of axially successive guide sections, wherein a circumferential guide groove with at least one nozzle bore penetrating the guide casing is formed on one of the guide sections of the guide casing and wherein the guide section in the interior of the Guide shell is associated with a compressed air supply. Thus, the thread without additional auxiliary guide means can advantageously lead in several wraps on the guide shell of the combination unit. In one of the guide sections, the thread is guided in the guide groove, in which, in an angular position of the guide jacket, an air treatment can be carried out on the thread to produce interlacing nodes.
In Abhängigkeit von den Verfahrensparametern und dem Fadentyp lässt sich der Führungsabschnitt mit der Führungsnut gemäß einer vorteilhaften Variante der erfindungsgemäßen Galetteneinheit an einer Randzone des Führungsmantels oder in einem mittleren Bereich des Führungsmantels ausbilden.Depending on the process parameters and the thread type, the guide section can be formed with the guide groove according to an advantageous variant of the godet unit according to the invention at an edge zone of the guide casing or in a central region of the guide casing.
Um unabhängig von der Lage in der Führungsnut an dem Führungsmantel eine für die Verwirbelung optimale Fadenspannung zwischen den Fadenumschlingungen einstellen zu können, ist die Galetteneinheit bevorzugt derart ausgeführt, dass der Führungsabschnitt mit der Führungsnut an einer Durchmesserstufe des Führungsmantels ausgebildet ist.In order to be able to set an optimum for the turbulence thread tension between the Fadenumschlingungen regardless of the position in the guide groove on the guide casing, the godet unit is preferably designed such that the guide portion is formed with the guide groove at a diameter stage of the guide casing.
Je nach Anforderung, ob eine Erhöhung der Fadenspannung oder eine Absenkung der Fadenspannung gewünscht ist, lässt sich der zur Führungsnut benachbarte Führungsabschnitt des Führungsmantels im Durchmesser gleichgroß oder ungleichgroß der Durchmesserstufe ausbilden. Somit ist eine hohe Flexibilität sowohl in der Führung als auch in der Verwirbelung des Fadens gegeben. Insbesondere lassen sich damit auch Geschwindigkeitsdifferenzen zwischen der Umfangsgeschwindigkeit der Führungsnut und des Fadens realisieren, um weitere Parameter zur Erzeugung von möglichst stabilen Verflechtungsknoten zu erhalten.Depending on the requirement, whether an increase in the thread tension or a reduction in the thread tension is desired, the adjacent guide groove to the guide section of the guide sheath in Diameter equal or unequal sized form the diameter stage. Thus, a high flexibility is given both in the leadership and in the swirling of the thread. In particular, speed differences between the peripheral speed of the guide groove and the thread can thus also be realized in order to obtain further parameters for generating as stable as possible interlacing nodes.
Die Führungsabschnitte des Führungsmantels können hierbei zylindrisch oder auch konisch ausgebildet sein.The guide portions of the guide shell can be cylindrical or conical.
Um die Fadenführung und die Fadenverwirbelung an dem Kombinationsaggregat unabhängig voneinander ausführen zu können, ist das Kombinationsaggregat gemäß einer besonders vorteilhaften Weiterbildung der Erfindung derart ausgebildet, dass das Kombinationsaggregat einen drehend angetriebenen Führungsmantel und ein dem Führungsmantel zugeordneten drehenden Düsenring aufweist, der am Umfang an eine umlaufende Führungsnut und zumindest eine in die Führungsnut mündende Düsenbohrung aufweist, wobei der Düsenring mit einer im Innern des Düsenringes angeordneten Druckluftzuführeinrichtung zusammenwirkt. Hierbei wird der Düsenring koaxial zu dem Führungsmantel angeordnet, wobei der Düsenring entweder den zulaufenden Faden oder aber auch den ablaufenden Faden aufnehmen kann. Grundsätzlich besteht dabei auch die Möglichkeit, dass der Führungsmantel des Kombinationsaggregates und der Düsenring unabhängig voneinander angetrieben werden. Somit lässt sich der Führungsmantel als beheizte Galette oder unbeheizte Galette ausbilden.In order to perform the thread guide and the Fadenverwirbelung to the combination unit independently, the combination unit according to a particularly advantageous embodiment of the invention is designed such that the combination unit has a rotating driven guide sheath and the guide sheath associated rotating nozzle ring on the circumference to a circumferential Guiding and at least one opening into the guide groove nozzle bore, wherein the nozzle ring cooperates with a arranged in the interior of the nozzle ring compressed air supply. Here, the nozzle ring is arranged coaxially to the guide casing, wherein the nozzle ring can accommodate either the incoming thread or else the running thread. Basically, there is also the possibility that the guide casing of the combination unit and the nozzle ring are driven independently. Thus, the guide sheath can be formed as a heated galette or unheated galette.
Bevorzugt ist jedoch die Ausführung der Galetteneinheit, bei welcher der Führungsmantel und der Düsenring des Kombinationsaggregates mit einer Antriebswelle verbunden sind und synchron durch einen Elektroantrieb antreibbar ausgebildet sind. Der Düsenring und der Führungsmantel können hierbei gleichgroße oder ungleich große Durchmesser aufweisen, so dass ebenfalls die Fadenspannung oder eine Relativgeschwindigkeit zwischen dem Faden und der Führungsnut des Düsenringes einstellbar sind.However, preferred is the execution of the godet unit, in which the guide casing and the nozzle ring of the combination unit are connected to a drive shaft and are designed to be drivable synchronously by an electric drive. The nozzle ring and the guide casing can in this case have the same size or unequal diameter, so that also the thread tension or a relative speed between the thread and the guide groove of the nozzle ring are adjustable.
Unabhängig davon, ob das Kombinationsaggregat aus einem Führungsmantel oder aus einem Führungsmantel und einem separaten Düsenring gebildet ist, lässt sich die Druckluftzuführeinrichtung bevorzugt durch einen Stator mit einer Druckkammer und einer Kammeröffnung ausbilden, der mit der Kammeröffnung an einer Innenseite des Führungsmantels oder an einer Innenseite des Düsenringes gegenüberliegend zu der Führungsnut angeordnet ist. Der Stator ist ortsfest und wird mit seiner Kammeröffnung bevorzugt in einen mittleren Bereich einer durch die Teilumschlingung des Fadens gebildete Kontaktstrecke zwischen Faden und Führungsnut angeordnet.Regardless of whether the combination unit is formed from a guide casing or from a guide casing and a separate nozzle ring, the compressed air supply device can preferably be formed by a stator having a pressure chamber and a chamber opening which communicates with the chamber opening on an inner side of the guide casing or on an inner side of the Nozzle ring is arranged opposite to the guide groove. The stator is stationary and is preferably arranged with its chamber opening in a central region of a formed by the partial looping of the thread contact distance between the thread and guide groove.
Um bei dem Übergang von dem stationären Stator auf die in der Führungsnut ausgebildete Düsenbohrung ohne größere Druckverluste zu ermöglichen, ist gemäß einer vorteilhaften Weiterbildung der Stator mit einer Gleitfläche ausgebildet, in welcher die Kammeröffnung mündet und welche gegenüber der Innenseite des Führungsmantels oder gegenüber der Innenseite des Düsenringes einen Dichtspalt bildet. Somit lässt sich der Stator an eine innere Kontur des Führungsmantels oder an einer innere Kontur des Düsenringes optimal anpassen.In order to allow for the transition from the stationary stator to the nozzle bore formed in the guide groove without major pressure losses, according to an advantageous embodiment of the stator is formed with a sliding surface in which the chamber opening opens and which with respect to the inside of the guide casing or against the inside of the Nozzle ring forms a sealing gap. Thus, the stator can be optimally adapted to an inner contour of the guide casing or to an inner contour of the nozzle ring.
Besonders vorteilhaft und für die Gleichmäßigkeit der erzeugten Verflechtungsknoten ist die Galetteneinheit gemäß einer vorteilhaften Weiterbildung derart ausgeführt, dass der Führungsnut auf einer Außenseite gegenüberliegend zum Stator eine ortsfeste Abdeckung zugeordnet ist, die sich radial über einen Teilbereich der Führungsnut erstreckt. Damit ist der Faden während der Verwirbelung in einer abgedeckten Führungsnut geführt.According to an advantageous further development, the godet unit is particularly advantageous and designed for the uniformity of the generated interlacing nodes such that the guide groove on an outer side opposite the stator is assigned a stationary cover which extends radially over a partial region of the guide groove. Thus, the thread is guided during the turbulence in a covered guide.
Um ebenfalls nach Möglichkeit keine höheren Luftverluste in die Umgebung zu behalten, weist die Abdeckung eine an dem Umfang der Führungsnut angepasste Dichtfläche auf, die mit einem Spalt oberhalb zum Führungsabschnitt oder zum Düsenring angeordnet ist. Insoweit wird die Druckluft im Wesentlichen zu beiden Seiten der Abdeckung durch die Führungsnut abgeleitet.In order to retain as far as possible no higher air losses into the environment, the cover has a matched to the circumference of the guide groove sealing surface which is arranged with a gap above the guide portion or the nozzle ring. In that regard, the compressed air is substantially derived on both sides of the cover by the guide groove.
Für den Fall, dass bei dem Kombinationsaggregat der Führungsmantel mehrere Führungsabschnitte aufweist, wobei zumindest eine der Führungsabschnitte eine Führungsnut zumindest einer Düsenbohrung im Nutgrund enthält, lässt sich vorteilhaft unmittelbar eine derart ausgebildete Galette verwenden. Insoweit ist eine erfindungsgemäße Galette mit einem drehend angetriebenen Führungsmantel besonders bevorzugt in einer derartigen Galetteneinheit verwendet. Die Führungsabschnitte der Führungsmäntel, die benachbart zu dem Führungsabschnitt mit der umlaufenden Führungsnut ausgebildet sind, können alternativ auch zusätzlich beheizt werden.In the event that in the combination aggregate of the guide casing has a plurality of guide portions, wherein at least one of the guide portions includes a guide groove at least one nozzle bore in the groove bottom, can advantageously directly use such a trained godet. In that regard, a godet according to the invention with a rotatably driven guide sheath is particularly preferably used in such a galette unit. The guide sections of the guide shells, which are formed adjacent to the guide section with the circumferential guide groove, can alternatively also be heated.
Die erfindungsgemäße Galetteneinheit ist insbesondere in Schmelzspinnprozessen, in welchen multifile Fäden erzeugt werden, zum Führen und Verwirbeln der Fäden geeignet. Grundsätzlich können dabei auch mehrere Fäden parallel nebeneinander im Führungsmantel geführt werden. Hierbei würde jedem der Fäden eine separate Führungsnut zur Verwirbelung zugeordnet.The godet unit according to the invention is particularly suitable in melt spinning processes, in which multifilament threads are produced, for guiding and swirling the threads. In principle, several threads can be guided parallel to each other in the guide sheath. In this case, each of the threads would be assigned a separate guide groove for swirling.
Die erfindungsgemäße Galetteneinheit wird nachfolgend anhand einiger Ausführungsbeispiele unter Bezug auf die beigefügten Figuren nachfolgend näher erläutert.The godet unit according to the invention will be explained in more detail below with reference to some embodiments with reference to the accompanying figures.

Das Ausführungsbeispiel der erfindungsgemäßen Galetteneinheit zum Führen von einem multifilen Faden weist ein Kombinationsaggregat 1 und eine in Abstand dem Kombinationsaggregat 1 zugeordnete Beilaufrolle 17 auf. Das Kombinationsaggregat 1 ist derart ausgebildet, dass es innerhalb der Galetteneinheit die Funktion einer Galette 30 und die Funktion einer Verwirbelungseinrichtung 21 übernimmt. Das Kombinationsaggregat 1 weist hierzu einen antreibbaren Führungsmantel 2 auf, der über einen mittleren Steg 26 und eine Nabe 11 mit einer Antriebswelle 6 drehfest verbunden ist. Der Steg 26 und die Nabe 5 sind innerhalb des zylindrischen Führungsmantels 2 ausgebildet.The embodiment of the godet unit according to the invention for guiding a multifilament yarn has a
Am Umfang des Führungsmantels 2 sind mehrere axial hintereinander liegende Führungsabschnitte 4.1 und 4.2 ausgebildet. An einem ersten Führungsabschnitt 4.1, der in diesem Ausführungsbeispiel eine rechte Randzone des Führungsmantels 2 bildet, ist eine umlaufende Führungsnut 7 ausgebildet. Im Nutgrund der Führungsnut 7 mündet eine Düsenbohrung 8. In diesem Ausführungsbeispiel sind in der Führungsnut 7 zwei um 180° versetzt angeordnete Düsenbohrungen 8 ausgebildet. Die Düsenbohrungen 8 durchdringen den Führungsmantel 2 bis zu seiner Innenseite. Im Innern des Führungsmantels 2 ragt von einer Antriebsseite her eine Druckluftzuführeinrichtung 9 in das Innere des Führungsmantels 2. Die Druckluftzuführeinrichtung 9 ist in diesem Ausführungsbeispiel durch einen zylindrischen Stator 10 gebildet, der im Zentrum eine Lagerbohrung 24 aufweist, in welcher die Antriebswelle 6 durch mehrere Lager 23 drehbar gelagert ist. Innerhalb des Führungsmantels 2 erweist der Stator 10 einen Führungskragen 12 mit einer äußeren Gleitfläche 28 auf, die an den Innendurchmesser des Führungsmantels 2 angepasst ist. Der Stator 10 ist ortsfest und wird über einen Galettenträger 3 gehalten.At the periphery of the guide casing 2 a plurality of axially successive guide sections 4.1 and 4.2 are formed. At a first guide section 4.1, which forms a right edge zone of the
Auf einer zur Beilaufrolle 17 gegenüberliegenden Seite des Führungsmantels 2 weist der Stator eine Druckkammer 15 auf, die über einen Druckluftanschluss 11 mit einer hier nicht dargestellten Druckluftquelle gekoppelt ist. Die Druckkammer 15 weist im Bereich des Führungskragens 12 eine Kammeröffnung 16 auf, die mit der umlaufenden Führungsnut 7 in einer gemeinesamen Ebene angeordnet ist. Die Kammeröffnung 16 mündet in die Gleitflächen 28, so dass die in der Führungsnut 7 angeordneten Düsenbohrungen 8 bei Drehung des Führungsmantels 2 abwechselnd in den Öffnungsbereich der Kammeröffnung 16 gelangen. Die Kammeröffnung 16 ist in radialer Richtung als ein Langloch ausgebildet, so dass sich eine definierte Öffnungszeit an der jeweiligen Düsenbohrung 8 einstellt, in welcher eine aus der Druckkammer 15 austretender Druckluftstrom impulsartig über die Düsenbohrung 8 in die Führungsnut 7 gelangt.On a side opposite the

Gegenüberliegend zur Kammeröffnung 16 im Stator 10 ist der Führungsnut 7 an dem Führungsabschnitt 4.1 eine Abdeckung 13 zugeordnet. Die Abdeckung 13 ist über eine Schwenkachse 14 beweglich an dem Galettenträger 3 gehalten, so dass die Abdeckung 13 zu Prozessbeginn zum Einfädeln des Fadens von der Führungsnut 7 wegbewegt werden kann.Opposite the chamber opening 16 in the
Die Abdeckung 13 erstreckt sich in radialer Richtung über einen Teilbereich der Führungsnut 7, wobei die Abdeckung 13 eine an den Umfang der Führungsnut 7 angepasste Dichtfläche 31 aufweist, die mit einem Dichtspalt 29 oberhalb zum Führungsabschnitt 4.1 angeordnet ist.The
Am Umfang des Führungsmantels 2 ist im ersten Führungsabschnitt 4.1 unmittelbar ein zweiter Führungsabschnitt 4.2 zugeordnet. Der zweite Führungsabschnitt 4.2 und der erste Führungsabschnitt 4.1 weisen einen identischen Aussendurchmesser auf, so dass die Führungsnut 7 am Umfang des Führungsabschnittes 4.1 eine Vertiefung bildet. Der zweite Führungsabschnitt 4.2 erstreckt sich über den gesamten Bereich des Führungsmantels 2 bis hin zu einem frei hin auskragenden Stirnende. Die Länge des Führungsabschnittes 4.2 ist derart ausgebildet, dass ein Faden 20 gemeinsam mit der Beilaufrolle 17 in mehreren Umschlingungen führbar ist.At the periphery of the
Die Antriebswelle 6 wird in diesem Ausführungsbeispiel durch einen Elektromotor 19 angetrieben. Im Betrieb wird der Führungsmantel 2 mit einer vordefinierten Umfangsgeschwindigkeit angetrieben, so dass ein Faden von einem vorgeordneten Behandlungsaggregat abgezogen werden kann. In dem in
