Abstract

Ein seitlich auf einen Faden auftreffender Luftstrahl kann einen laufenden Faden durch eine Öffnung transportieren. Dieses "Anlegen" von Fäden in Düsen versagt bei höheren Fadengeschwindigkeiten. Nach der Erfindung gelingt das Anlegen auch bei hohen Fadengeschwindigkeiten, wenn ein kräftiger Treibgasstrahl in der Düse aufgeteilt wird in Randstrahlen, die nach außen umgelenkt werden, und einen feinen Zentralstrahl, der den Faden durch die enge Öffnung befördert.An air jet hitting a thread laterally can transport a running thread through an opening. This "threading" of threads in nozzles fails at higher thread speeds. According to the invention, application is also possible at high thread speeds if a powerful jet of propellant gas is divided into edge jets which are deflected outwards and a fine central jet which conveys the thread through the narrow opening.

Description

Die Erfindung betrifft ein Verfahren zum automatischen Einführen eines oder mehrerer schnell laufender Fäden durch eine enge Öffnung, wobei der Faden zunächst quer vor der Öffnung vorbeigeführt wird, in Fadenlaufrichtung nach der Öffnung getrennt wird und mit einem senkrecht zur bisherigen Fadenlaufrichtung wirkenden Treibstrahl durch die öffnung befördert wird und eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for the automatic insertion of one or more fast-running threads through a narrow opening, the thread first being passed transversely in front of the opening, being separated in the thread running direction after the opening and being conveyed through the opening with a driving jet acting perpendicularly to the previous thread running direction is and an apparatus for performing the method.

Bei der Herstellung synthetischer Fäden muß die ersponnene Faser Behandlungsvorrichtungen durchlaufen, die eine enge Eingangsöffnung haben, beispielsweise eine Texturier-oder eine Falschdralldüse. Das Einführen eines Fadens durch die erwähnten öffnungen wird im nachfolgenden Text als "Anlegen" des Fadens bezeichnet,die enge Öffnung als "Düse" oder"Texturierdüse". Es sind Vorrichtungen, wie Einziehnadeln oder Schlingen bekannt, mit denen ein Faden angelegt werden kann. Es ist auch bekannt, mit einem Gasstrahl den vor der Öffnung laufenden abgetrennten Faden durch die öffnung zu "schießen". Mit den bekannten Vorrichtungen und Verfahren läßt sich jedoch nur arbeiten, wenn die Fadengeschwindigkeit nicht zu groß ist. Bei höheren Fadengeschwindigkeiten reicht der vom Gasstrahl auf den Faden übertragene Impuls nicht aus,um den Faden umzulenken,und der Faden verwickelt sich im Lieferwerk. Wird der Gasstrahl durch einen Flüssigkeitsstrahl ersetzt,wird die Düse innen feucht und muß erst durch das Behandlungsmedium getrocknet werden. Es wird dabei die Düse abgekühlt und bis zur Wiedererreichung der Solltemperatur vergehen mehrere Minuten,in denen Abfall produziert wird.In the production of synthetic threads, the spun fiber must pass through treatment devices which have a narrow entrance opening, for example a texturing or a false twist nozzle. The insertion of a thread through the openings mentioned is referred to in the following text as "applying" the thread, the narrow opening as a "nozzle" or "texturing nozzle". Devices, such as pull-in needles or loops, are known with which a thread can be put on. It is also known to "shoot" the separated thread running in front of the opening through the opening with a gas jet. With the known devices and methods can only work if the thread speed is not too high. At higher thread speeds, the momentum transferred from the gas jet to the thread is not sufficient to deflect the thread, and the thread becomes tangled in the delivery plant. If the gas jet is replaced by a liquid jet, the inside of the nozzle becomes damp and must first be dried by the treatment medium. The nozzle is cooled and several minutes pass in which waste is produced before the target temperature is reached again.

uer Erfindung liegt die Aufgabe zugrunde, mit hoher Geschwindigkeit laufende Fäden in eine enge öffnung einzuführen, ohne daß Faden und Vorrichtung mit Flüssigkeit benetzt werden. Das Verfahren soll auch anwendbar sein, wenn die Fadengeschwindigkeit über 3000 m/min liegt. Die Aufgabe wird verfahrensmäßig dadurch gelöst, daß ein Treibgasstrahl, dessen Querschnitt so groß ist, daß der Strahl nicht mehr vollständig durch die enge Öffnung gelangt, auf den Faden geblasen wird und dieser Strahl vor der engen öffnung durch eine vorgeschaltete Anordnung aufgespalten wird in einen zentralen Strahl, der durch die enge öffnung gelangt, und in Strahlen, die vor der engen öffnung abgeleitet werden.The invention is based on the object of inserting threads running at high speed into a narrow opening without the thread and device being wetted with liquid. The method should also be applicable if the thread speed is over 3000 m / min. The object is achieved procedurally in that a propellant gas jet, the cross section of which is so large that the jet no longer passes completely through the narrow opening, is blown onto the thread and this jet is split into a central one by an upstream arrangement in front of the narrow opening Beam that passes through the narrow opening and into beams that are derived in front of the narrow opening.

Mit dieser Erfindung wird erreicht, daß auch Fäden mit einer Abzugsgeschwindigkeit von über 4000 m/min durch enge öffnungen, wie beispielsweise durch Texturierdüsen, automatisch transportiert werden können und es ist überraschend, daß der Faden sicher in die Düse gelangt und nicht in die seitlichen Bohrungen gelangt.With this invention it is achieved that threads with a take-off speed of over 4000 m / min can be automatically transported through narrow openings, such as for example through texturing nozzles, and it is surprising that the thread arrives safely in the nozzle and not in the lateral bores reached.

Es ist vorteilhaft,wenn zum Anlegen des Fadens in eine Behandlungsvorrichtung das gleiche Fluid verwendet wird, das sich auf gleicher Temperatur befinden soll, wie das zur Garnbehandlung benutzte Fluid.It is advantageous if the same fluid that is to be at the same temperature as the fluid used for the yarn treatment is used to apply the thread in a treatment device.

Es ist weiter vorteilhaft,wenn die der engen Öffnung vorgeschaltete Anordnung aus einem Fadeneinlaufkanal besteht, der sich zu einem Ringraum erweitert,und in dem Ringraum an der Seite nach außen führende Bohrungen oder Kanäle vorhanden sind.It is further advantageous if the arrangement upstream of the narrow opening consists of a thread inlet channel which widens into an annular space, and bores or channels leading outwards on the side are provided in the annular space.

Das erfindungsgemäße Verfahren ist im folgenden beispielhaft beschrieben und in den Zeichnungen dargestellt. Es zeigen:The method according to the invention is described below by way of example and illustrated in the drawings. Show it:

  • 2 thread flow and gas flow before application in a texturing nozzle,
  • Fig. 3 thread flow and gas flow after application in a texturing nozzle.

Der Öffnung 1 der Texturierdüse ist eine Anordnung 2 vorgeschaltet. Diese enthält einen Fadeneinlaufkanal 3, der sich zu einem Ringraum 4 erweitert. Am seitlichen Umfang des Ringraumes 4 sind Bohrungen 5 zur Gasableitung vorhanden.An arrangement 2 is arranged upstream of the opening 1 of the texturing nozzle. This contains a thread inlet channel 3, which widens into an annular space 4. On the lateral circumference of the annular space 4 there are bores 5 for gas discharge.

In den Figuren 2 und 3 ist der Fadenlauf und die Gasströmung schematisch dargestellt. Der Faden 6 läuft vor dem Fadeneinlaufkanal 3 vorbei. Für den Anlegevorgang wird die Treibdüse 7 über das Ventil 8 mit Treibgas beaufschlagt und durch eine beliebige Schneidvorrichtung 9 der Faden 6 in Fadenlaufrichtung nach dem Fadeneinlaufkanal 3 getrennt. Der Faden wird durch das aus 7 auströmende Treibgas in den Fadeneinlaufkanal 3 transportiert. Im Ringraum 4 wird der Treibstrahl so aufgespalten, daß ein zentraler Strahl den Faden 6 in die Öffnung 1 der Texturierdüse transportiert und daß ein Teil des Treibstahls durch die seitlichen Bohrungen 5 nach außen gelangt.In Figures 2 and 3, the thread path and the gas flow is shown schematically. The thread 6 runs in front of the thread inlet channel 3. For the application process, the propellant nozzle 7 is acted upon by propellant gas via the valve 8 and the thread 6 in the thread running direction by any cutting device 9 separated after the thread inlet channel 3. The thread is transported into the thread inlet channel 3 by the propellant gas flowing out of 7. In the annular space 4, the driving jet is split up so that a central jet transports the thread 6 into the opening 1 of the texturing nozzle and that part of the driving steel passes through the lateral bores 5 to the outside.

In der in Figur 3 dargestellten Arbeitsstellung wird das (erwärmte) Treibgas zur Fadenbehandlung verwendet. Das Garn wird durch das über 10 zuströmende Gas weitergefördert.In the working position shown in Figure 3, the (heated) propellant gas is used for thread treatment. The yarn is conveyed further by the inflowing gas.

Der Fadeneinlaufkanaldurchmesser beträgt 1,3 mm, der Durchmesser des Ringraums 2,6 mm bei einer Tiefe von 2 mm. Die teilweise Abführung der Randstrahlen des Treibgases erfolgt durch zwei Bohrungen von je 0,8 mm Durchmesser. Die Treibdüse hat einen Durchmesser von 0,7 mm. Als Treibmittel wird Dampf mit einem Vordruck von 9 bar und einer Temperatur von 2300C eingesetzt.The thread 150 dtex / 34 f has a running speed of 3500 m / min. It is to be applied to a texturing nozzle whose nozzle inlet diameter is 1 mm. The thread inlet channel diameter is 1.3 mm, the diameter of the annular space 2.6 mm at a depth of 2 mm. The marginal jets of the propellant gas are partially discharged through two holes, each 0.8 mm in diameter. The driving nozzle has a diameter of 0.7 mm. Steam with a pre-pressure of 9 bar and a temperature of 230 ° C. is used as the blowing agent.
