Description

Die Erfindung betrifft eine Texturiermaschine zum Verstrecken und Kräuseln synthetischer Fäden gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a texturing machine for drawing and crimping synthetic threads according to the preamble of claim 1.

Eine gattungsgemäße Texturiermaschine ist aus der WO 2004/018749 A1 bekannt.A generic texturing machine is from WO 2004/018749 A1 known.

Die bekannte Texturiermaschine weist eine Vielzahl von Bearbeitungsstellen auf, um in jeder der Bearbeitungsstellen einen Faden zu verstrecken und zu kräuseln. Hierzu sind in den Bearbeitungsstellen jeweils mehrere Lieferwerke, mehrere Behandlungseinrichtungen und eine Spuleinrichtung zum Aufwickeln des gekräuselten und verstreckten Fadens zu einer Spule angeordnet. Hierzu sind die Lieferwerke und die Behandlungseinrichtungen üblicherweise innerhalb eines Maschinengestells zu einem Fadenlauf angeordnet. Um bei einem Prozessbeginn das Einfädeln des Fadens in einer der Bearbeitungsstellen zu erleichtern, weist die bekannte Texturiermaschine eine pneumatische Hilfseinrichtung mit mehreren Führungsrohren und mehreren Injektoren auf. So lässt sich der Faden in der Bearbeitungsstelle pneumatisch der Spuleinrichtung zuführen. Die Spuleinrichtung weist eine Absaugung auf, durch welche der Faden in der Spuleinrichtung aufgenommen und zum Einfädeln geführt wird.The known texturing machine has a large number of processing points in order to stretch and crimp a thread in each of the processing points. For this purpose, several delivery systems, several treatment devices and a winding device for winding the crimped and drawn thread into a spool are arranged in the processing points. For this purpose, the delivery systems and the treatment devices are usually arranged within a machine frame to form a yarn path. In order to facilitate the threading of the thread in one of the processing points at the start of a process, the known texturing machine has a pneumatic auxiliary device with a number of guide tubes and a number of injectors. In this way, the thread can be fed pneumatically to the winding device in the processing point. The winding device has a suction device, through which the thread is received in the winding device and guided for threading.

Bei der bekannten Texturiermaschine müssen hierzu teilweise größere Fadenabstände zwischen den Blasöffnungen und Saugöffnungen der Hilfseinrichtung zur Übergabe des Fadens überbrückt werden. Derartige Abstände erfordern jedoch eine exakte Ausrichtung der sich gegenüberliegenden Blasöffnungen und Saugöffnungen der pneumatischen Hilfseinrichtung sowie der in der Spuleinrichtung vorgesehenen Absaugung.In the case of the known texturing machine, larger thread distances between the blow openings and suction openings of the auxiliary device for transferring the thread have to be bridged in some cases for this purpose. However, such distances require an exact alignment of the blow openings and suction openings of the pneumatic auxiliary device located opposite one another and of the suction provided in the winding device.

Es ist daher Aufgabe der Erfindung, die gattungsgemäße Texturiermaschine zum Verstrecken und Kräuseln synthetischer Fäden derart zu verbessern, dass eine sichere Fadenführung beim Einfädeln eines Fadens bis zur Spuleinrichtung in einer der Bearbeitungsstellen zu Prozessbeginn möglich ist.It is therefore the object of the invention to improve the generic texturing machine for stretching and crimping synthetic threads in such a way that reliable thread guidance is possible when threading a thread up to the winding device in one of the processing points at the start of the process.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Absaugeinrichtung einen schwenkbaren Saugrüssel aufweist, welcher zur Übernahme des Fadens mit einem kurzen Abstand gegenüberliegend zum Blasende des Führungsrohres positionierbar ist.This object is achieved according to the invention in that the suction device has a pivotable suction nozzle which can be positioned at a short distance opposite the blowing end of the guide tube in order to take over the thread.

Vorteilhafte Weiterbildungen sind durch die Merkmale und Merkmalskombinationen der jeweiligen Unteransprüche definiert.Advantageous developments are defined by the features and feature combinations of the respective dependent claims.

Die Erfindung besitzt den besonderen Vorteil, dass zur Übernahme des Fadens in der Spuleinrichtung die Hilfseinrichtung mit einer positionierbaren Absaugeinrichtung zusammenwirkt. So lässt sich über den schwenkbaren Saugrüssel ein möglichst minimaler Abstand zwischen dem Blasende des Führungsrohres und der Absaugeinrichtung realisieren. Zudem lässt sich über die Bewegbarkeit des Saugrüssels dieser mit hoher Genauigkeit gegenüber dem Blasende des Führungsrohres positionieren.The invention has the particular advantage that the auxiliary device interacts with a suction device that can be positioned to take over the thread in the winding device. In this way, the smallest possible distance between the blowing end of the guide tube and the suction device can be achieved via the swiveling suction nozzle. In addition, the mobility of the suction nozzle allows it to be positioned with great accuracy relative to the blowing end of the guide tube.

Die Weiterbildung der erfindungsgemäßen Texturiermaschine, bei welcher der Abstand zwischen einer Saugöffnung des Saugrüssels und einer Blasöffnung des Führungsrohres in einer Übergabeposition des Saugrüssels <150mm ist, ist besonders vorteilhat, um Fäden sowohl mit feinem Titer als auch Fäden mit grobem Titer fangsicher zu übertragen. Bei größeren Abständen oberhalb 150 mm können insbesondere Luftwiderstände bei feinen Fadentitern ungewünschte Ablenkungen erzeugen.The development of the texturing machine according to the invention, in which the distance between a suction opening of the suction nozzle and a blowing opening of the guide tube in a transfer position of the suction nozzle is <150mm, is particularly advantageous for securely transferring threads with both fine titers and threads with coarse titers. At greater distances above 150 mm, air resistance in particular can produce undesirable deflections with fine yarn deniers.

Um den vom Saugrüssel übernommenen Faden unmittelbar der Spuleinrichtung zuführen zu können, ist die Weiterbildung der Erfindung bevorzugt ausgeführt, bei welcher der Saugrüssel der Absaugeinrichtung der Spuleinrichtung im Fadenlauf vorgeordnet ist und innerhalb eines Drehwinkel von mind. 180° bewegbar ist. Somit lässt sich einerseits der Abstand zwischen der Saugöffnung des Saugrüssels und der Blasöffnung des Blasendes weiter reduzieren. Andererseits kann der dem Saugrüssel kontinuierlich zulaufende Faden mittels der Bewegung des Saugrüssels der Spuleinrichtung übergeben werden. So ist beispielsweise bekannt, dass die zum Halten einer Spulhülse verwendeten Klemmteller sowohl Fang- als auch Schneidmittel aufweisen, um einen laufenden Faden zu übernehmen.In order to be able to feed the thread taken from the suction nozzle directly to the winding device, the further development of the invention is preferably designed in which the suction nozzle of the suction device is arranged upstream of the winding device in the thread path and can be moved within a rotation angle of at least 180°. Thus, on the one hand, the distance between the suction opening of the suction nozzle and the blowing opening of the blowing end can be further reduced. On the other hand, the thread running continuously to the suction nozzle can be transferred to the winding device by means of the movement of the suction nozzle. For example, it is known that the clamping plates used to hold a bobbin tube have both catching and cutting means in order to take over a running thread.

Damit eine möglichst genaue Positionierung und Ausrichtung des Saugrüssels gegenüber dem Blasende des Führungsrohres möglich ist, wird als Schwenkantrieb bevorzugt ein Schrittmotor eingesetzt. Damit eine wiederkehrende exakte Positionierung des Saugrüssels gegenüber einem stationären Blasende des Führungsrohres möglich.So that the suction nozzle can be positioned and aligned as precisely as possible with respect to the blowing end of the guide tube, a stepper motor is preferably used as the swivel drive. This enables a recurring exact positioning of the suction nozzle in relation to a stationary blowing end of the guide tube.

Üblicherweise wird innerhalb einer Bearbeitungsstelle der Faden durch ein Lieferwerk der Spuleinrichtung zugeführt. Zur Einfädelung des Fadens an einem Lieferwerk ist hierzu die Weiterbildung der Erfindung vorgesehen, bei welchem das Führungsrohr gegenüberliegend zum Blasende einen der Führungsrohre einen der Injektoren mit einem Saugrohr aufweist, wobei ein Saugende des Saugrohres einer schwenkbaren Andruckrolle eines der Lieferwerke zugeordnet ist, welche Andruckrolle mit einer Lieferwelle zur Führung des Fadens zusammenwirkt und wobei ein Blasende eines weiteren Führungsrohres der Andruckrolle im Fadenlauf vorgeordnet ist. So lässt sich der Faden im Betrieb durch einen Klemmspalt zwischen der Andruckrolle und der Lieferwelle führen. Zum Einfädeln ist die Andruckrolle schwenkbar ausgeführt, so dass ein Einfädeln möglich wird.Within a processing point, the thread is usually fed to the winding device by a delivery system. For threading the thread on a delivery system, the development of the invention is provided for this purpose, in which the guide tube opposite the blowing end of one of the guide tubes has one of the injectors with a suction tube, with a suction end of the suction tube being assigned to a pivotable pressure roller of one of the delivery systems, which pressure roller with a delivery shaft for guiding the thread and wherein a blowing end of another guide tube is arranged in front of the pressure roller in the thread path. In this way, the thread can be guided through a clamping gap between the pressure roller and the delivery shaft during operation. For threading, the pressure roller is pivotable so that threading is possible.

Hierzu kreuzt eine Verbindungslinie zwischen dem Blasende des vorgeordneten Führungsrohres und einem Saugende des nachgeordneten Saugrohres eine Bewegungsbahn der Andruckrolle. Damit ist gewährleistet, dass ein zwischen dem Blasende und dem Saugende gespannter Faden allein durch die Bewegung der Andruckrolle erfasst werden kann.For this purpose, a connecting line between the blowing end of the upstream guide tube and a suction end of the downstream suction tube crosses a movement path of the pressure roller. This ensures that a thread stretched between the blowing end and the suction end can be gripped solely by the movement of the pressure roller.

Die Andruckrolle ist hierzu an einem beweglichen Klemmhalter gehalten, welcher durch ein Halterantrieb zwischen einer Einfädeleinstellung oder einer Klemmstellung führbar ist. Somit kann die Andruckrolle automatisiert nach dem Einfädeln des Fadens in die Klemmstellung geführt werden.For this purpose, the pressure roller is held on a movable clamping holder, which can be guided by a holder drive between a threading setting and a clamping position. In this way, the pressure roller can be automatically guided into the clamping position after threading the thread.

Da innerhalb eines Maschinengestells die Prozessaggregate und Lieferwerke nicht in einem geraden Fadenlauf hintereinander angeordnet werden können, sondern Umlenkungen zwischen den Prozessaggregaten und Lieferwerken unumgänglich sind, kommt der Weiterbildung der erfindungsgemäßen Texturiermaschine eine besondere Bedeutung zu, bei welchem dem Saugende des nachgeordneten Saugrohres eine Prallplatte zugeordnet ist, die gegenüberliegend einer Blasöffnung vom Blasende des vorgeordneten Führungsrohres angeordnet ist. So wird das lose Fadenende, das aus einer Blasöffnung eines Blasendes ausgeblasen wird durch die gegenüberliegende Prallplatte aufgefangen und ermöglicht eine direkte Übernahme durch eine Saugöffnung am Saugende des Saugrohres. Somit lassen sich auch speziell Fadenumlenkungen ohne starke Krümmungen in den Führungsrohren und Saugrohren überwinden.Since the processing units and delivery systems cannot be arranged one behind the other in a straight thread path within a machine frame, but deflections between the processing units and delivery systems are unavoidable, the further development of the texturing machine according to the invention is of particular importance, in which the suction end of the downstream suction pipe has a baffle plate is assigned, which is arranged opposite a blowing opening from the blowing end of the upstream guide tube. In this way, the loose thread end that is blown out of a blowing opening of a blowing end is caught by the opposite baffle plate and enables it to be taken over directly through a suction opening at the suction end of the suction pipe. This means that thread deflections in particular can also be overcome without sharp bends in the guide tubes and suction tubes.

Die Weiterbildung der erfindungsgemäßen Texturiermaschine, bei welcher das vorgeordnete Führungsrohr einen weiteren Injektor mit einem Saugrohr aufweist, das an einem Auslass einer Heizröhre einer Heizeinrichtung angeschlossen ist, wird bevorzugt bei den Bearbeitungsstellen eingesetzt, bei welcher vor dem Aufwickeln des Fadens eine thermische Behandlung zum Abbau von Spannungen erforderlich ist. Damit besteht die Möglichkeit, dass der Faden über einen Einlass der Heizröhre der Heizeinrichtung aufgenommen und mit Hilfe der Hilfseinrichtung automatisiert der Spuleinrichtung zugeführt wird. Damit ergeben sich wesentliche Vorteile beim Einfädeln der Fäden in den Bearbeitungsstellen, die den Aufwand für einen Operator minimieren und zudem eine sichere Übergabe des Fadens in die Spuleinrichtung gewährleisten.The development of the texturing machine according to the invention, in which the upstream guide tube has a further injector with a suction tube which is connected to an outlet of a heating tube of a heating device, is preferably used at the processing points in which a thermal treatment is carried out before the thread is wound up to break down tension is required. This makes it possible for the thread to be taken up via an inlet of the heating tube of the heating device and automatically fed to the winding device with the aid of the auxiliary device. This results in significant advantages when threading the threads in the processing points, which minimize the effort for an operator and also ensure a safe transfer of the thread into the winding device.

Die erfindungsgemäße Texturiermaschine ist nachfolgend anhand eines Ausführungsbeispiels unter Bezug auf die beigefügten Figuren näher erläutert.The texturing machine according to the invention is explained in more detail below using an exemplary embodiment with reference to the attached figures.

In der Fig. 1 ist schematisch eine Bearbeitungsstelle der erfindungsgemäßen Texturiermaschine zum Verstrecken und Kräuseln eines synthetischen Fadens schematisch dargestellt. Derartige Texturiermaschinen weisen üblicherweise eine Vielzahl von Bearbeitungsstellen auf, die innerhalb eines Maschinengestells nebeneinander angeordnet sind. Der Aufbau der Bearbeitungsstellen innerhalb der Texturiermaschine ist hierbei identisch ausgebildet, so dass jede der Bearbeitungsstellen mehrere Lieferwerke, mehrere Behandlungseinrichtungen und eine Spuleinrichtung zum Wickeln einer Spule aufweisen. Hierbei werden die Lieferwerke, die Behandlungseinrichtungen und die Spuleinrichtung zum Wickeln einer Spule in dem Maschinengestell zu einem bestimmten Fadenlauf angeordnet. Da die Behandlungseinrichtungen und Lieferwerke im Verhältnis zu der Spuleinrichtung eine geringere Breite aufweisen, sind somit mehrere Spuleinrichtungen in dem Maschinengestell etagenförmig übereinander und nebeneinander angeordnet. Da derartige Maschinenkonstruktion der Texturiermaschinen allgemein bekannt sind, wird hier nur ein Schema einer der Bearbeitungsstellen mit den darin enthaltenen Lieferwerken, Behandlungseinrichtungen und Spuleinrichtung in Fig. 1 gezeigt.In the 1 a processing point of the texturing machine according to the invention for stretching and crimping a synthetic thread is shown schematically. Such texturing machines usually have a large number of processing points which are arranged next to one another within a machine frame. The design of the processing points within the texturing machine is identical here, so that each of the processing points has a number of delivery mechanisms, a number of treatment devices and a winding device for winding a coil. In this case, the delivery systems, the treatment devices and the winding device for winding a bobbin are arranged in the machine frame for a specific thread run. Since the treatment devices and delivery mechanisms have a smaller width in relation to the winding device, several winding devices are arranged in tiers one above the other and next to each other in the machine frame. Since such machine constructions of texturing machines are generally known, only a schematic of one of the processing points with the delivery mechanisms, treatment devices and winding device contained therein is shown here 1 shown.

Bei dem Ausführungsbeispiel nach Fig. 1 sind insgesamt drei Lieferwerke 3, 7 und 19 vorgesehen, um einen Faden zu führen. Ein erstes Lieferwerk 3 ist durch eine angetriebene Galette 3.1 und eine Überlaufrolle 3.2 gebildet. Hierbei schließt das erste Lieferwerk 3 und da nachfolgende zweite Lieferwerk 7 eine sogenannte Texturierzone ein, in welcher als Behandlungseinrichtungen eine erste Heizeinrichtung 4, eine Kühleinrichtung 5 und eine Kräuseleinrichtung 6 angeordnet sind. Das zweite Lieferwerk 7 wird in diesem Ausführungsbeispiel ebenfalls durch eine angetriebene Galette 7.1 und eine Überlaufrolle 7.2 gebildet.In the embodiment according to 1 are a total of three delivery mechanisms 3, 7 and 19 provided to guide a thread. A first delivery mechanism 3 is formed by a driven godet 3.1 and an overflow roller 3.2. The first delivery mechanism 3 and the subsequent second delivery mechanism 7 enclose a so-called texturing zone in which a first heating device 4, a cooling device 5 and a crimping device 6 are arranged as treatment devices. In this exemplary embodiment, the second delivery mechanism 7 is also formed by a driven godet 7.1 and an overflow roller 7.2.

Im weiteren Verlauf folgt dem zweiten Lieferwerk 7 eine zweite Heizeinrichtung 10 und das dritte Lieferwerk 19, durch welches der Faden zur Spuleinrichtung 21 geführt wird. Das dritte Lieferwerk 19 wird in diesem Fall durch eine Lieferwelle 19.1 und eine Andruckrolle 19.2 gebildet, die über einen Klemmhalter 19.3 am Umfang der angetriebenen Lieferwelle 19.1 gehalten ist. Dem Klemmhalter 19.3 ist ein Halterantrieb 19.4 zugeordnet, durch welche die Andruckrolle 19.2 schwenkbar ist.In the further course, the second delivery mechanism 7 is followed by a second heating device 10 and the third delivery mechanism 19, through which the thread is guided to the winding device 21. In this case, the third delivery mechanism 19 is formed by a delivery shaft 19.1 and a pressure roller 19.2, which is held on the circumference of the driven delivery shaft 19.1 by a clamping holder 19.3. A holder drive 19.4, through which the pressure roller 19.2 can be pivoted, is assigned to the clamp holder 19.3.

Die Spuleinrichtung 21 ist schematisch dargestellt und weist einen Spulenhalter 21.1, eine Treibwalze 21.4 und mehrere am Ende des Spulenhalters 21.1 angeordnete Klemmteller 21.2 auf, die eine hier nicht dargestellte Spulhülse tragen. Die Treibwalze 21.4 ist angetrieben. Zur Führung des Fadens beim Wickeln einer Spule ist der Treibwalze 21.4 eine Changiereinrichtung 21.5 vorgeordnet, die einen oszillierend angetriebenen Changierfadenführer aufweist.The winding device 21 is shown schematically and has a bobbin holder 21.1, a drive roller 21.4 and a plurality of clamping plates 21.2 arranged at the end of the bobbin holder 21.1 and carrying a bobbin tube, not shown here. The drive roller 21.4 is driven. To guide the thread when winding a bobbin, the drive roller 21.4 is preceded by a traversing device 21.5, which has an oscillatingly driven traversing thread guide.

Der zweiten Heizeinrichtung 10, dem dritten Lieferwerk 19 sowie der Spuleinrichtung 21 ist eine pneumatische Hilfseinrichtung 11 zugeordnet, um bei einem Prozessbeginn ein Einfädeln des Fadens zu ermöglichen. Die Hilfseinrichtung 11 wirkt dabei mit einer Absaugeinrichtung 22 zusammen, die im Fadenlauf der Spuleinrichtung 21 vorgeordnet ist. In diesem Ausführungsbeispiel weist die Absaugeinrichtung 22 einen schwenkbaren Saugrüssel 22.1 auf, der über einen Schwenkantrieb 22.2 zwischen mehreren Positionen verschwenkbar ist. In der in Fig. 1 dargestellten Situation befindet sich der Saugrüssel 22.1 in einer Übergabeposition, in welcher das Einfädeln eines Fadens erfolgt.A pneumatic auxiliary device 11 is assigned to the second heating device 10, the third delivery system 19 and the winding device 21 in order to enable threading of the thread at the start of a process. The auxiliary device 11 interacts with a suction device 22 which is arranged upstream of the winding device 21 in the yarn path. In this exemplary embodiment, the suction device 22 has a pivotable suction nozzle 22.1, which can be pivoted between a number of positions via a pivot drive 22.2. in the in 1 In the situation shown, the suction nozzle 22.1 is in a transfer position in which a thread is threaded.

In der Übergabeposition des Saugrüssels 22.1 liegt eine Saugöffnung 22.3 des Saugrüssels 22.1 genau gegenüber einer Blasöffnung 16 von einem Blasende 15.2 eines Führungsrohres 12.2. Das Führungsrohr 12.2 der Hilfseinrichtung 11 weist an einem gegenüberliegenden Ende zum Blasende 15.2 einen Injektor 13.2 auf. Der Injektor 13.2 weist auf der Saugseite ein Saugrohr 14.2 auf, das ein Saugende 17.2 mit einer Saugöffnung 18 enthält. Das Saugende 17.2 des Injektors 13.2 ist im kurzen Abstand dem dritten Lieferwerk 19 zugeordnet.In the transfer position of the suction nozzle 22.1, a suction opening 22.3 of the suction nozzle 22.1 is located exactly opposite a blowing opening 16 of a blowing end 15.2 of a guide tube 12.2. The guide tube 12.2 of the auxiliary device 11 has an injector 13.2 at an end opposite to the blowing end 15.2. The injector 13.2 has a suction pipe 14.2 on the suction side, which contains a suction end 17.2 with a suction opening 18. The suction end 17.2 of the injector 13.2 is assigned to the third delivery system 19 at a short distance.

Auf der gegenüberliegenden Seite des dritten Lieferwerkes 19 ist ein weiteres Führungsrohr 12.1 der Hilfseinrichtung 11 angeordnet. Das dem dritten Lieferwerk 19 vorgeordnete Führungsrohr 12.1 ragt mit seinem Blasende 15.1 bis zum dritten Lieferwerk 19. An dem zum Blasende 15.1 gegenüberliegenden Ende weist das Führungsrohr 12.1 einen weiteren Injektor 13.1 auf, der auf seiner Saugseite mit einem Saugrohr 14.1 verbunden ist. Das Saugrohr 14.1 ist mit einem Auslass 10.3 einer Heizröhre 10.1 der Heizeinrichtung 10 gekoppelt.On the opposite side of the third delivery system 19, another guide tube 12.1 of the auxiliary device 11 is arranged. The guide tube 12.1 arranged upstream of the third delivery mechanism 19 projects with its blowing end 15.1 to the third delivery mechanism 19. At the end opposite the blowing end 15.1, the guide tube 12.1 has a further injector 13.1 which is connected on its suction side to a suction pipe 14.1. The suction tube 14.1 is coupled to an outlet 10.3 of a heating tube 10.1 of the heating device 10.

Zum Einfädeln eines Fadens 24 werden die Injektoren 13.1 und 13.2 mit einer Druckluftquelle (hier nicht dargestellt) verbunden, so dass an den jeweiligen Blasenden 15.1 und 15.2 der Führungsrohre 12.1 und 12.2 ein Blasstrom erzeugt wird. An den Saugenden 17.1 und 17.2 der Saugrohre 14.1 und 14.2 wird jeweils eine Saugströmung erzeugt. Die Saugwirkung des Injektors 13.1 wird über die Verbindung mit der Heizröhre 10.1 bis zu einem Einlass 10.2 der zweiten Heizeinrichtung 10 fortgepflanzt. Insoweit ist am Einlass 10.2 der Heizeinrichtung 10 eine Saugströmung vorhanden, durch welcher ein loses Fadenende in die Heizröhre 10.1 einsaugbar ist.To thread a thread 24, the injectors 13.1 and 13.2 are connected to a compressed air source (not shown here), so that a blowing current is generated at the respective blowing ends 15.1 and 15.2 of the guide tubes 12.1 and 12.2. A suction flow is generated at the suction ends 17.1 and 17.2 of the suction pipes 14.1 and 14.2. The suction effect of the injector 13.1 is propagated via the connection with the heating tube 10.1 to an inlet 10.2 of the second heating device 10. In this respect, there is a suction flow at the inlet 10.2 of the heating device 10, through which a loose thread end can be sucked into the heating tube 10.1.

Um einen Prozess zum Verstrecken und Kräuseln eines synthetischen Fadens der Bearbeitungsstelle zu starten, wird ein Faden 24 von einer Vorlagespule 1.1 abgezogen. Die Vorlagespule 1.1 ist an einem Gatterplatz 1 angeordnet und mit einer Reservespule 1.2 gekoppelt. Der Faden 24 wird hierzu durch einen Handinjektor 8 aufgenommen und mit mehreren Umschlingungen an das erste Lieferwerk 3 und nachfolgend in der ersten Heizeinrichtung 4, der Kühleinrichtung 5 und der Kräuseleinrichtung 6 eingefädelt. Anschließend wird der Faden 24 mit mehreren Umschlingungen an das zweite Lieferwerk 7 angelegt. Nun wird der Faden dem Einlass 10.2 der Heizröhre 10.1 zugeführt und durchtrennt, so dass ein loses Fadenende durch die Saugströmung des Injektors 13.1 in die Heizröhre 10.1 eingesogen und zum Blasende 15.1 des Führungsrohres 12.1 geführt. Um den Faden 24 an das dritte Lieferwerk 19 anzulegen, wird zusätzlich zu den Figuren 3.1 und 3.2 Bezug genommen.In order to start a process for stretching and crimping a synthetic thread at the processing point, a thread 24 is drawn off from a template spool 1.1. The template coil 1.1 is arranged at a gate location 1 and coupled to a reserve coil 1.2. For this purpose, the thread 24 is picked up by a hand injector 8 and threaded with several loops onto the first delivery system 3 and subsequently into the first heating device 4 , the cooling device 5 and the crimping device 6 . The thread 24 is then applied to the second delivery system 7 with several loops. The thread is now fed to the inlet 10.2 of the heating tube 10.1 and severed, so that a loose thread end is sucked into the heating tube 10.1 by the suction flow of the injector 13.1 and guided to the blowing end 15.1 of the guide tube 12.1. To create the thread 24 to the third delivery mechanism 19, in addition to the Figures 3.1 and 3.2 referenced.

In den Fig. 3.1 und 3.2 ist das dritte Lieferwerk 19 in verschiedenen Betriebssituationen vor und nach dem Einfädelvorgang dargestellt. So zeigt Fig. 3.1 die Betriebssituation des dritten Lieferwerkes 19 während des Einfädelns des Fadens durch die Hilfseinrichtung 11 und Fig. 3.2 die Situation, in welcher das dritte Lieferwerk 19 betriebsbereit ist.In the Figures 3.1 and 3.2 the third delivery mechanism 19 is shown in different operating situations before and after the threading process. So shows Figure 3.1 the operating situation of the third delivery system 19 during the threading of the thread by the auxiliary device 11 and Figure 3.2 the situation in which the third delivery mechanism 19 is operational.

Wie aus der Darstellung in Fig. 3.1 hervorgeht, ist dem Saugende 17.2 des Saugrohres 14.2 eine Prallplatte 20 zugeordnet. Die Prallplatte 20 erstreckt sich in dem Bereich der Saugöffnung 18 des Saugrohres 14.2.As shown in the illustration in Figure 3.1 shows that a baffle plate 20 is assigned to the suction end 17.2 of the suction pipe 14.2. The baffle plate 20 extends in the area of the suction opening 18 of the suction pipe 14.2.

Auf der zum dritten Lieferwerk 19 gegenüberliegenden Seite ist das Blasende 15.1 mit einer Blasöffnung 16 mit Abstand gegenüberliegend zu der Prallplatte 20 angeordnet. Die Andruckrolle 19.2 ist durch den Halterantrieb 19.4 und den Klemmhalter 19.3 in eine Einfädelposition geführt und bildet einen Freiraum zur Lieferwelle 19.1. In dieser Situation lässt sich ein loses Fadenende über das Blasende 15.1 in Richtung der Prallplatte 20 ausblasen, wobei die an dem Saugende 17.2 wirkende Saugströmung den Faden erfasst und über das Führungsrohr 12.2 weiterführt. In dieser Situation bildet der Faden 24 zwischen dem Blasende 15.1 und dem Saugende 17.2 eine Verbindungslinie, die eine Bewegungsbahn der Andruckrolle 19.2 kreuzt. Somit lässt sich der Faden 24 durch Verschwenken der Andruckrolle 19.2 selbsttätig in einen Klemmspalt zwischen der Andruckrolle 19.2 und der Lieferwelle 19.1 führen. Hierzu wird der Halterantrieb 19.4 aktiviert und die Andruckrolle 19.2 wird in ihre Klemmstellung geführt.On the opposite side to the third delivery system 19, the blowing end 15.1 is arranged with a blowing opening 16 at a distance opposite the baffle plate 20. The pressure roller 19.2 is guided into a threading position by the holder drive 19.4 and the clamping holder 19.3 and forms a free space for the delivery shaft 19.1. In this situation, a loose yarn end can be blown out via the blowing end 15.1 in the direction of the baffle plate 20, with the suction flow acting on the suction end 17.2 grasping the yarn and guiding it further via the guide tube 12.2. In this situation, the thread 24 forms a connecting line between the blowing end 15.1 and the sucking end 17.2, which crosses a movement path of the pressure roller 19.2. The thread 24 can thus be guided automatically into a clamping gap between the pressure roller 19.2 and the delivery shaft 19.1 by pivoting the pressure roller 19.2. For this purpose, the holder drive 19.4 is activated and the pressure roller 19.2 is guided into its clamping position.

Wie aus der Darstellung in Fig. 1 hervorgeht, wird der Faden zur Übergabe in die Spuleinrichtung 21 durch den Saugrüssel 22.1 der Absaugeinrichtung 22 übernommen. Hierzu ist das Blasende 15.2 mit einer Blasöffnung 16 der Spuleinrichtung 21 zugewandt. Der Saugrüssel 22.1 wird durch den Schwenkantrieb 22.2 in der Übergabeposition gehalten. In der Übergabeposition ist zwischen der Saugöffnung 22.3 des Saugrüssels 22.1 und der Blasöffnung 16 des Blasendes 15.2 ein Abstand ausgebildet. Der Abstand ist in Fig. 1 mit dem Großbuchstaben A gekennzeichnet. Der Abstand A zwischen dem Saugrüssel 22.1 und dem Blasende 15.2 ist hierbei kleiner 150 mm ausgeführt. In dieser Übergabeposition wird das lose Fadenende durch das Führungsrohr 12.2 aufgrund der Blasströmung des Injektors 13.2 aus dem Blasende 15.2 herausgeblasen und unmittelbar gegenüberliegend von der Saugöffnung 22.3 des Saugrüssels 22.1 der Absaugeinrichtung 22 aufgenommen. Der Saugrüssel 22.1 ist mit einer hier nicht dargestellten Abfallleitung gekoppelt, um dem Faden zu einem Abfallbehälter zu führen.As shown in the illustration in 1 shows that the thread is transferred to the winding device 21 by the suction nozzle 22.1 of the suction device 22. For this purpose, the blowing end 15.2 faces the winding device 21 with a blowing opening 16 . The suction nozzle 22.1 is held in the transfer position by the swivel drive 22.2. In the transfer position, a distance is formed between the suction opening 22.3 of the suction nozzle 22.1 and the blowing opening 16 of the blowing end 15.2. The distance is in 1 marked with the capital letter A. The distance A between the suction nozzle 22.1 and the blowing end 15.2 is made smaller than 150 mm. In this transfer position, the loose thread end is blown out of the blowing end 15.2 through the guide tube 12.2 due to the blowing flow of the injector 13.2 and is picked up directly opposite by the suction opening 22.3 of the suction nozzle 22.1 of the suction device 22. The suction nozzle 22.1 is coupled to a waste line, not shown here, in order to lead the thread to a waste container.

Zur weiteren Erläuterung wird neben der Fig. 1 auch zu der Fig. 2 Bezug genommen. In Fig. 2 ist die Spuleinrichtung 21 in einer Draufsicht dargestellt. Insoweit gilt die nachfolgende Beschreibung für beide Figuren.For further explanation next to the 1 also to that 2 referenced. In 2 the winding device 21 is shown in a plan view. In this respect, the following description applies to both figures.

Wie aus der Fig. 2 hervorgeht, ist eine Spulhülse 21.3 zwischen den Klemmtellern 21.2 gespannt und wird von dem Spulenhalter 21.1 an der Treibwalze 21.4 gehalten. Der Saugrüssel 22.1 befindet sich in Fig. 2.1 ebenfalls in der Übergabeposition. Sobald der Faden von dem Saugrüssel 22.1 erfasst ist, wird der Schwenkantrieb 22.2 aktiviert, um dem Saugrüssel 22.1 um einen Drehwinkel im Bereich von mind. 180° zu verschwenken. So lässt sich der Saugrüssel 22.1 dem Klemmteller 21.2 zuführen, durch welchen eine Übernahme des Fadens folgt. Diese Situation ist in Fig. 2 gestrichelt dargestellt. Der Schwenkantrieb 22.2 des Saugrüssels 22.1 ist vorzugsweise als ein Schrittmotor ausgeführt, um eine wiederholbare und exakte Positionierung zur Übernahme und zur Weitergabe des Fadens einstellen zu können. In der Fig. 2 ist der Drehwinkel des Saugrüssels mit dem Bezugskennzeichen α dargestellt.How from the 2 shows, a bobbin tube 21.3 is clamped between the clamping plates 21.2 and is held by the bobbin holder 21.1 on the drive roller 21.4. The suction nozzle 22.1 is also in the transfer position in FIG. 2.1. As soon as the thread is gripped by the suction nozzle 22.1, the swivel drive 22.2 is activated in order to swivel the suction nozzle 22.1 through a rotation angle in the range of at least 180°. In this way, the suction nozzle 22.1 can be fed to the clamping plate 21.2, through which the thread is taken over. This situation is in 2 shown dashed. The swivel drive 22.2 of the suction nozzle 22.1 is preferably designed as a stepping motor in order to be able to set a repeatable and exact positioning for the takeover and for the passing on of the thread. In the 2 the angle of rotation of the suction nozzle is shown with the reference α.

Wie aus der Darstellung in Fig. 1 hervorgeht, ist das Führungsrohr 12.1 der Hilfseinrichtung 11 unterhalb einer Plattform 23 angeordnet. Da die Spuleinrichtungen 21 benachbarter Bearbeitungsstellen etagenförmig unterhalb oder oberhalb der dargestellten Spuleinrichtung 31 angeordnet sind, weisen die benachbarten Führungsrohre 12.2 der benachbarten Hilfseinrichtungen unterschiedliche Längen auf. Die Spuleinrichtungen sind daher bevorzugt an einem Wickelgestellt angeordnet, das gegenüber einem Prozessgestell, in welcher die zweite Heizeinrichtung 10 gehalten ist, einen Bedienungsgang vorsieht. Insoweit ist das Führungsrohr 12.1 bevorzugt zur Überbrückung einer unteren Plattform 23 vorgesehen. Hierzu ist in Fig. 1 schematisch die Situation eines Bedienungsganges aufgezeigt.As shown in the illustration in 1 shows, the guide tube 12.1 of the auxiliary device 11 is arranged below a platform 23. Since the winding devices 21 of adjacent processing points are arranged in tiers below or above the winding device 31 shown, the adjacent guide tubes 12.2 of the adjacent auxiliary devices have different lengths. The winding devices are therefore preferably arranged on a winding stand that provides an operating aisle opposite a process stand in which the second heating device 10 is held. In this respect, the guide tube 12.1 is preferably provided for bridging a lower platform 23. For this is in 1 schematically shows the situation of a service aisle.

Grundsätzlich ist die in Fig. 1 dargestellte Anordnung der Hilfseinrichtung 11 jedoch nicht auf bestimmte Querschnittsformen von Maschinengestellen beschränkt. Wesentlich hierbei ist, dass die sich zwischen den Blasenden 15.1 und 15.2 und den Saugenden 17.1 und 17.2 ausbildenden Freistrecken möglichst kurz gehalten werden, um eine sichere und reproduzierbare Fadenführung beim Einfädeln des Fadens zu erhalten.Basically, the in 1 However, the arrangement of the auxiliary device 11 shown is not limited to specific cross-sectional shapes of machine frames. It is essential here that the free sections formed between the blowing ends 15.1 and 15.2 and the suction ends 17.1 and 17.2 are kept as short as possible in order to obtain reliable and reproducible thread guidance when threading the thread.
