Definitions
- the invention relates to a melt spinning device for a plurality of multifilament yarns according to the preamble of claim 1 and to a process for applying a plurality of multifilament yarns in a melt spinning device according to the preamble of claim 15.
- a plurality of strand-like filaments are first extruded from a plurality of spinnerets.
- each of the spinnerets has a plurality of nozzle bores, so that the filament strands extruded from a spinneret form a filament bundle.
- each of the filament bundles is brought together separately to form a thread, so that a so-called first convergence point is formed in the spinning line.
- This convergence point which defines the merger of the individual filament strands, is assigned to the spinnerets, so that a thread pitch is established which is substantially equal to a center distance of two adjacent spinnerets.
- a spinning device is for example from the DE 199 29 817 A1 known.
- the filament bundles are brought together in the convergence point by a preparation device into individual threads. Subsequently, the threads are guided with small thread spacing side by side in the downstream treatment device and treated.
- the individual filament bundles are picked up by a manually guided suction device, preferably a suction gun, and withdrawn continuously from the spinnerets. Subsequently, the separation of the held together in a suction filament bundle to the threads in the convergence point and a merging of the threads to a treatment distance.
- the separation is a time-consuming manual work, while much waste is produced. A quick application of the threads is therefore desirable to avoid larger amounts of waste.

- Each filament bundle forms a straight line between the suction opening and the respective associated spinneret. Due to the center distance between the spinnerets, which is also referred to in the art as a nozzle division, these straight lines run at an angle to each other on the opening of the suction device.
- the convergence points of the filament bundles can be defined independently of the center distance of the spinnerets.

- the filament bundles can thus be advantageously introduced from their natural run out into the preparation device.
- the auxiliary guiding means is preferably formed by a deflecting rod with sliding edge extending parallel to the thread lubrication means and held on a pivoting arm.
- the filament bundles can be applied in a simple manner before separating on the sliding edge of the deflection bar. Even with a larger distance between the preparation device and the application aid, the thread spacings which increase during the guidance of the suction device can occur without hindrance on the deflection bar of the auxiliary guidance means.
- a plurality of thread oiling means are associated with a thread, wherein the yarn oiling means associated with a thread adjoin with their thread guiding surfaces face.
- the auxiliary guide means can be supplemented by a second deflecting bar, which is assigned to the downstream thread guiding means.

- the development of the invention according to claim 11 is particularly advantageous for this purpose.
- the Tangelvorraum is disposed in the transition between the spinning plane and the treatment level, wherein the individual thread channels of the Tangelvorraum offset from each other.
- the threads can be introduced in a simple manner after threading in the Tangelvortechnisch in a subsequent treatment device such as a drafting system.
- the application of the threads can be further improved by arranging an auxiliary separating device in the thread run between the spinneret and the placement aid, by means of which the predispensing of the filament bundles takes place during application.
- the Hilfsseparier rose can be formed by separating plates in a chute or preferably by a shaped sheet with multiple cuts, which is pivotally movable between the cooling shaft and a chute in the yarn path.

Description
Die Erfindung betrifft eine Schmelzespinnvorrichtung für mehrere multifile Fäden gemäß dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zum Anlegen mehrerer multifiler Fäden in einer Schmelzespinnvorrichtung gemäß dem Oberbegriff des Anspruchs 15.The invention relates to a melt spinning device for a plurality of multifilament yarns according to the preamble of claim 1 and to a process for applying a plurality of multifilament yarns in a melt spinning device according to the preamble of
Bei der Herstellung von schmelzgesponnenen multifilen Endlosfäden werden zunächst aus mehreren Spinndüsen eine Vielzahl von strangförmigen Filamenten extrudiert. Jede der Spinndüsen weist hierzu eine Vielzahl von Düsenbohrungen auf, so dass die aus einer Spinndüse extrudierten Filamentstränge ein Filamentbündel bilden. Jedes der Filamentbündel wird nach Abkühlung der Filamentstränge separat zu einem Faden zusammengeführt, so dass sich in der Spinnlinie ein so genannter erster Konvergenzpunkt ausbildet. Dieser Konvergenzpunkt, welcher den Zusammenschluss der einzelnen Filamentstränge definiert, ist den Spinndüsen zugeordnet, so dass sich ein Fadenabstand einstellt, der im wesentlichen gleich einem Mittenabstand zweier benachbarter Spinndüsen ist. Eine derartige Spinnvorrichtung ist beispielsweise aus der
Bei der bekannten Spinnvorrichtung werden die Filamentbündel in dem Konvergenzpunkt durch eine Präparationseinrichtung zu einzelnen Fäden zusammengeführt. Anschließend werden die Fäden mit kleinem Fadenabstand nebeneinander in den nachgeordneten Behandlungseinrichtung geführt und behandelt.In the known spinning device, the filament bundles are brought together in the convergence point by a preparation device into individual threads. Subsequently, the threads are guided with small thread spacing side by side in the downstream treatment device and treated.
Zum Erstanlegen der Fäden ist es üblich, dass nach dem Anspinnen der Filamentbündel durch die Spinneinrichtung die einzelnen Filamentbündel durch eine manuell geführte Absaugeinrichtung vorzugsweise eine Saugpistole gemeinsam aufgenommen werden und kontinuierlich von den Spinndüsen abgezogen werden. Anschließend erfolgt nacheinander die Separierung der in einer Saugöffnung zusammengehaltenen Filamentbündel zu den Fäden in dem Konvergenzpunkt und ein Zusammenführen der Fäden zu einem Behandlungsabstand. Dabei ist insbesondere die Separierung eine zeitraubende manuelle Arbeit, während der viel Abfall entsteht. Ein schnelles Anlegen der Fäden ist daher zur Vermeidung größerer Abfallmengen wünschenswert.For the first application of the threads, it is customary that after piecing the filament bundles through the spinning device, the individual filament bundles are picked up by a manually guided suction device, preferably a suction gun, and withdrawn continuously from the spinnerets. Subsequently, the separation of the held together in a suction filament bundle to the threads in the convergence point and a merging of the threads to a treatment distance. In particular, the separation is a time-consuming manual work, while much waste is produced. A quick application of the threads is therefore desirable to avoid larger amounts of waste.
Um möglichst an jedem der Fäden gleiche physikalische Eigenschaften zu erhalten, ist es bei den bekannten Spinnvorrichtungen des weiteren bekannt, bestimmte Auslenkwinkel zum Zusammenführen der Fäden in den Behandlungsabstand nicht zu überschreiten. Somit sind bei einer Vielzahl von parallel gesponnenen Fäden größere Bauhöhen der Schmelzspinnvorrichtung unumgänglich, das wiederum die Anlegeprozedur der Fäden zum Separieren und Zusammenführen erschwert.In order to obtain the same physical properties as possible on each of the threads, it is also known in the known spinning devices not to exceed certain deflection angles for bringing the threads into the treatment distance. Thus, in a plurality of parallel-spun threads larger heights of the melt spinning device are inevitable, which in turn complicates the application procedure of the threads for separating and merging.

Es ist nun Aufgabe der Erfindung, eine Schmelzspinnvorrichtung der gattungsgemäßen Art mit einer Fadenführung auszugestalten, die eine geringe Bauhöhe der Schmelzespinnvorrichtung sowie ein schnelles Erstanlegen der Fäden ermöglicht.It is an object of the invention to provide a melt spinning device of the generic type with a thread guide, which allows a low overall height of the melt spinning device and a fast Erstanlegen the threads.
Eine weitere Aufgabe der Erfindung ist es, ein Verfahren zum Anlegen der multifilen Fäden zu schaffen, bei welchem ein hoher Automatisierungsgrad erreichbar ist.A further object of the invention is to provide a method for applying the multifilament threads, in which a high degree of automation can be achieved.
Diese Aufgabe wird erfindungsgemäß durch eine Schmelzspinnvorrichtung für mehrere multifile Fäden mit den Merkmalen nach Anspruch 1 sowie durch ein Verfahren zum Anlegen multifiler Fäden in einer Schmelzspinnvorrichtung mit den Merkmalen nach Anspruch 15 gelöst.This object is achieved by a melt spinning apparatus for a plurality of multifilament yarns with the features of claim 1 and by a method for applying multifilament yarns in a melt spinning apparatus having the features of
Vorteilhafte Weiterbildungen der Erfindung sind durch die Merkmale und Merkmalskombinationen der Unteransprüche definiert.Advantageous developments of the invention are defined by the features and feature combinations of the subclaims.
Die Erfindung beruht auf der Erkenntnis, dass die Filamentbündel aus einzelnen Spinndüsen extrudiert werden, die einen Abstand zueinander aufweisen. Beim Anspinnen und Anlegen der Filamentbündel werden diese gemeinsam von einer Absaugvorrichtung aufgenommen, so dass alle Filamentstränge der Filamentbündel in einer Saugöffnung der Absaugvorrichtung zusammengeführt werden. Jedes Filamentbündel bildet dabei eine Gerade zwischen der Saugöffnung und der jeweils zugeordneten Spinndüse. Aufgrund des Mittenabstand zwischen den Spinndüsen, der in der Fachwelt auch als Düsenteilung bezeichnet wird, laufen diese Geraden mit einem Winkel zueinander auf die Öffnung der Absaugvorrichtung zu. Somit lassen sich die Konvergenzpunkte der Filamentbündel unabhängig von dem Mittenabstand der Spinndüsen definieren. Die erfindungsgemäße Schmelz-spinnvorrichtung weist ein Anlegehilfsmittel mit mehreren Separierfadenführern im Fadenlauf hinter der Präparationseinrichtung auf. Die Separierfadenführer besitzen einen Fadenabstand, welcher Fadenabstand wesentlich kleiner ist als der Mittenabstand zwischen den Spinndüsen, wobei den Separierfadenführern ein Führungsblech zugeordnet ist, das zu jedem Separierfadenführer ein Führungsschlitz aufweist. Somit werden die insbesondere äußeren Filamentbündel in der Schmelzspinnvorrichtung mit einer Auslenkung derart geführt, dass sich der Abstand zwischen den Filamentbündeln bis zum Separieren ständig verkleinert. Der Fadenabstand beim Separieren der Filamentbündel ist dabei derart gewählt, dass einerseits keine gegenseitige Beeinflussung der Filamentbündel eintritt und andererseits eine zulässige maximale Auslenkung der Filamentstränge nicht überschritten wird.The invention is based on the finding that the filament bundles are extruded from individual spinnerets which are at a distance from each other. When piecing and applying the filament bundles they are shared by a Suction taken so that all filament strands of the filament bundles are brought together in a suction opening of the suction device. Each filament bundle forms a straight line between the suction opening and the respective associated spinneret. Due to the center distance between the spinnerets, which is also referred to in the art as a nozzle division, these straight lines run at an angle to each other on the opening of the suction device. Thus, the convergence points of the filament bundles can be defined independently of the center distance of the spinnerets. The melt-spinning device according to the invention has a landing aid with several Separierfadenführern in the yarn path behind the preparation device. The Separierfadenführer have a thread pitch, which thread spacing is substantially smaller than the center distance between the spinnerets, wherein the Separierfadenführern a guide plate is assigned, which has a guide slot for each Separierfadenführer. Thus, the particular outer filament bundles are guided in the melt spinning device with a deflection such that the distance between the filament bundles is constantly reduced until separation. The thread spacing when separating the filament bundles is chosen such that on the one hand no mutual influence of the filament bundles occurs and on the other hand, a permissible maximum deflection of the filament strands is not exceeded.
Aufgrund des verringerten Fadenabstands beim Separieren der Filamentbündel lassen sich die Filamentbündel vorteilhaft beim Anlegen unmittelbar durch die Absaugvorrichtung führen. Bei einer manuell geführten Absaugvorrichtung in Form einer Absaugpistole kann der Separiervorgang durch einfache Handhabung durch eine Bedienperson ausgeführt werden. Ein zusätzlicher manueller Bediengang durch Vereinzelung der Filamentbündel aufgrund zu großer Fadenabstände kann entfallen.Due to the reduced thread spacing when separating the filament bundles, the filament bundles can advantageously be guided directly through the suction device during application. In a manually guided suction device in the form of a suction gun, the separation process can be carried out by simple handling by an operator. An additional manual operation by separating the filament bundles due to excessive thread distances can be omitted.
Um bereits vor dem Separieren das Anlegen der Filamentbündel in der vorgeordneten Präparationseinrichtung zu ermöglichen, ist die Weiterbildung der Erfindung gemäß Anspruch 2 besonders vorteilhaft. Hierbei ist der Präparationseinrichtung ein Hilfsführungsmittel zugeordnet, welches Hilfsführungsmittel zum Einführen der Fäden in die Präparationseinrichtung aus einer Auslenkposition in eine Betriebsposition bewegbar ist.In order to enable the filament bundles to be created in the upstream preparation device even before separation, the development of the invention according to claim 2 is particularly advantageous. Here, the preparation device is associated with an auxiliary guide means, which auxiliary guide means for insertion the threads in the preparation device from a deflection position in an operating position is movable.
Besonders vorteilhaft ist hierbei die Ausbildung des Hilfsführungsmittels mit einer Gleitkante, an denen die Filamentbündel geführt sind. Damit ist unabhängig vom Abstand der Absaugvorrichtung zu dem Hilfsfübrungsmittel jeder sich einstellende Fadenabstand realisierbar.Particularly advantageous here is the formation of the auxiliary guide means with a sliding edge on which the filament bundles are guided. Thus, regardless of the distance of the suction device to the Hilfsfübrungsmittel each adjusting thread spacing can be realized.
Um durch Verstellung des Hilfsführungsmittels eine Einfädelung der Filamentbündel in die Präparationseinrichtung zu erhalten, ist die Präparationseinrichtung vorteilhaft derart im Fadenlauf den Separierfadenführern vorgeordnet, dass die Filamentbündel ohne wesentliche Umlenkung zwischen der Spinndüse und einer der Präparationseinrichtung nachgeordneten Fadenführung führbar sind. Die Filamentbündel lassen sich somit vorteilhaft aus ihrem natürlichen Lauf heraus in die Präparationseinrichtung einführen.In order to obtain a threading of the filament bundles in the preparation device by adjusting the auxiliary guide means, the preparation device is advantageously upstream of the Separierfadenführern in the threadline that the filament bundles without substantial deflection between the spinneret and one of the preparation device downstream thread guide are feasible. The filament bundles can thus be advantageously introduced from their natural run out into the preparation device.
Für den Fall, dass die Präparationseinrichtung mehrere den Fäden zugeordnete Fadenölungsmittel aufweist, wird das Hilfsführungsmittel vorzugsweise durch eine sich parallel zu den Fadenölungsmitteln erstreckende Umlenkstange mit Gleitkante gebildet, welche an einem Schwenkarm gehalten ist. Somit können die Filamentbündel auf einfache Art und Weise vor dem Separieren an der Gleitkante der Umlenkstange angelegt werden. Selbst bei größerem Abstand zwischen der Präparationseinrichtung und der Anlegehilfe können die während der Führung der Absaugvorrichtung sich vergrößernden Fadenabstände an der Umlenkstange des Hilfsführungsmittels ohne Behinderung eintreten. Durch Verschwenken der Umlenkstange aus der Auslenkposition in die Betriebsposition werden nach dem Separieren die Filamentbündel selbsttätig in die Fadenölungsmittel einlaufen.In the event that the preparation device has a plurality of thread oiling means associated with the threads, the auxiliary guiding means is preferably formed by a deflecting rod with sliding edge extending parallel to the thread lubrication means and held on a pivoting arm. Thus, the filament bundles can be applied in a simple manner before separating on the sliding edge of the deflection bar. Even with a larger distance between the preparation device and the application aid, the thread spacings which increase during the guidance of the suction device can occur without hindrance on the deflection bar of the auxiliary guidance means. By pivoting the deflecting rod from the deflection position to the operating position, the filament bundles are automatically run into the thread oiling agent after separation.
Um bei größerer Filamentzahl eine intensive Benetzung des Filamentbündels zu erhalten, werden mehrere Fadenölungsmittel einem Faden zugeordnet, wobei die einem Faden zugeordneten Fadenölungsmittel sich mit ihren Fadenführungsflächen gegenüberstehen. Hierbei lässt sich vorteilhaft das Hilfsführungsmittel um eine zweite Umlenkstange ergänzen, die den nachgeordneten Fadenführungsmitteln zugeordnet ist.In order to obtain an intensive wetting of the filament bundle with a larger number of filaments, a plurality of thread oiling means are associated with a thread, wherein the yarn oiling means associated with a thread adjoin with their thread guiding surfaces face. In this case, advantageously, the auxiliary guide means can be supplemented by a second deflecting bar, which is assigned to the downstream thread guiding means.
Bei einer besonders vorteilhaften Weiterbildung der Erfindung weist das Hilfsführungsmittel neben der Umlenkstange eine sich mit Abstand parallel zu der Umlenkstange erstreckende Auslenkstange auf, die gemeinsam mit der Umlenkstange zwischen einer Auslenkposition und einer Betriebsposition verschwenkbar ist. In der Betriebsposition werden die Fäden durch die Auslenkstange an die Fadenölungsmittel gehalten.In a particularly advantageous embodiment of the invention, the auxiliary guide means in addition to the deflection bar on a distance parallel to the deflection bar extending Auslenkstange, which is pivotable together with the deflection bar between a deflection position and an operating position. In the operating position, the threads are held by the Auslenkstange to the Fadenölungsmittel.
Um das Separieren der einzelnen Filamentbündel mit möglichst kleinem Fadenabstand und damit in einer Position relativ nahe einem Divergenzpunkt der Absaugpistole durchführen zu können, ist die Weiterbildung der Erfindung besonders vorteilhaft, bei welcher die Separierfadenführer an einem Führungsblech ausgebildet sind. Hierbei ist jedem der Separierfadenführer ein Führungsschlitz in dem Führungsblech zugeordnet, die in einer Anlegkante des Führungsbleches münden. Dabei ist der Abstand zwischen dem Führungsschlitz an der Anlegkante vorzugsweise kleiner ausgebildet als der Fadenabstand zwischen den Separierfadenführem. Zum Einfädeln der Filamentbündel in den Führungsschlitz lässt sich die Absaugvorrichtung mit der Saugöffnung in relativ kleinem Abstand zu der Anlegekante führen.In order to carry out the separation of the individual filament bundles with the smallest possible thread spacing and thus in a position relatively close to a divergence point of the suction gun, the development of the invention is particularly advantageous, in which the Separierfadenführer are formed on a guide plate. Here, each of the Separierfadenführer is associated with a guide slot in the guide plate, which open into a contact edge of the guide plate. The distance between the guide slot at the contact edge is preferably smaller than the thread spacing between the Separierfadenführem. To thread the filament bundles into the guide slot, the suction device can be guided with the suction opening at a relatively small distance from the contact edge.
Das Anlegen der Fäden in die nachfolgende Behandlungseinrichtung ist für den Fall besonders vorteilhaft, bei welchem den Separierfadenführern unmittelbar eine Tangelvorrichtung nachgeordnet ist. In diesem Fall kann das Einfädeln in die Tangelvorrichtung mit Hilfe der Separierfadenführer erfolgen.The application of the threads in the subsequent treatment device is particularly advantageous for the case in which the Separierfadenführern immediately downstream of a Tangelvorrichtung. In this case, threading into the tying device can be done by means of the separating thread guides.
Dabei ist es besonders vorteilhaft, wenn der Tangelvorrichtung ein erstes Führungsblech mit den Separierfadenführern vorgeordnet und ein zweites Führungsblech mit mehreren Auslauffadenführern nachgeordnet ist. Die Führungsbleche weisen vorzugsweise Führungsschlitze zum Einführen der Fäden auf, die somit ein sicheres Einfädeln in die Tangelvorrichtung ermöglichen.It is particularly advantageous if the Tangelvorrichtung upstream of a first guide plate with the Separierfadenführern and a second guide plate is arranged downstream with a plurality of outlet yarn guides. The guide plates preferably have guide slots for insertion of the threads, which thus allow a secure threading in the Tangelvorrichtung.
In vielen Fällen sind die Behandlungseinrichtungen um 90° verdreht zu den Spinndüsenreihen angeordnet. In diesen Fällen ist es somit erforderlich, dass die Fäden aus einer Spinnebene in eine Behandlungsebene überführt werden müssen. Die Weiterbildung der Erfindung gemäß Anspruch 11 ist hierzu besonders vorteilhaft. Die Tangelvorrichtung ist in dem Übergang zwischen der Spinnebene und der Behandlungsebene angeordnet, wobei die einzelnen Fadenkanäle der Tangelvorrichtung versetzt zueinander angeordnet sind. Damit lassen sich die Fäden auf einfache Art und Weise nach dem Einfädeln in die Tangelvorrichtung in eine nachfolgende Behandlungseinrichtung beispielsweise einem Streckwerk einführen.In many cases, the treatment devices are arranged rotated by 90 ° to the spinneret rows. In these cases, it is thus necessary that the threads must be transferred from a spinning plane to a treatment level. The development of the invention according to
Bei einer großen Anzahl von parallel gesponnenen Fäden lässt sich das Anlegen der Fäden noch dadurch verbessern, dass in dem Fadenlauf zwischen der Spinndüse und dem Anlegehilfsmittel eine Hilfssepariereinrichtung angeordnet ist, durch welche die Vorteilung der Filamentbündel während des Anlegens erfolgt.In the case of a large number of parallel-spun threads, the application of the threads can be further improved by arranging an auxiliary separating device in the thread run between the spinneret and the placement aid, by means of which the predispensing of the filament bundles takes place during application.
Die Hilfssepariereinrichtung kann durch Trennbleche in einem Fallschacht oder vorzugsweise durch ein Formblech mit mehreren Einschnitten gebildet werden, welches beweglich zwischen dem Kühlschacht und einem Fallsschacht in den Fadenlauf einschwenkbar ist.The Hilfssepariereinrichtung can be formed by separating plates in a chute or preferably by a shaped sheet with multiple cuts, which is pivotally movable between the cooling shaft and a chute in the yarn path.
Das erfindungsgemäße Verfahren zum Anlegen mehrerer multifiler Fäden in eine Schmelzspinnvorrichtung zeichnet sich durch eine einfache und schnelle Handhabung durch eine Bedienperson aus. Nachdem die Filamentbündel angesponnen und durch die Saugöffnung einer Absaugvorrichtung vorzugsweise einer Saugpistole aufgenommen wurden, lassen sich die Filamentbündel durch Führung der Saugpistole auf einfache Art und Weise mit Hilfe des Anleghilfsmittels separieren und führen.The inventive method for applying a plurality of multifilament yarns in a melt spinning device is characterized by a simple and quick handling by an operator. After the filament bundles have been spun and taken up by the suction opening of a suction device, preferably a suction gun, the filament bundles can be separated and guided by guiding the suction gun in a simple manner with the help of the positioning aid.
Hierbei werden die Filamentbündel vorzugsweise vor der Separierung zur Einführung in die Präparationseinrichtung an ein Hilfsführungsmittel angelegt, durch welches die Filamentbündel bis zur Separierung in einer Auslenkposition geführt sind. Zur Einführung der Filamentbündel in die Präparationseinrichtung wird das Hilfsführungsmittel aus der Auslenkposition in eine Betriebsposition verschwenkt. Dabei werden die Filamente selbsttätig in die Präparationseinrichtung eingeführt.Here, the filament bundles are preferably applied before separation for introduction into the preparation device to an auxiliary guide means, through which the filament bundles are guided until separation in a deflection position. To introduce the filament bundles into the preparation device, the auxiliary guide means is pivoted from the deflection position into an operating position. The filaments are automatically introduced into the preparation device.
Nachfolgend wird die erfindungsgemäße Schmelzspinnvorrichtung sowie das Verfahren zum Anlegen der multifilen Fäden in der Schmelzspinnvorrichtung anhand einiger Ausführungsbeispiele unter Bezug auf die beigefügten Figuren näher erläutert.Hereinafter, the melt spinning apparatus of the present invention and the method for applying the multifilament yarns in the melt spinning apparatus will be explained in more detail with reference to some embodiments with reference to the accompanying drawings.

In den
Insoweit kein ausdrücklicher Bezug zu einer der Figuren gemacht ist, gilt die nachfolgende Beschreibung für alle Figuren.Unless expressly made to any of the figures, the following description applies to all figures.
Die Schmelzspinnvorrichtung weist mehrere Spinndüsen 2.1, 2.2 und 2.3 auf, die an einer Unterseite eines beheizbaren Spinnbalkens 1 angeordnet sind. Den Spinndüsen 2.1 und 2.2 und 2.3 ist eine Schmelzeverteilung 3 zugeordnet, die mit einem Schmelzeerzeuger (hier nicht dargestellt) verbunden ist. Unterhalb der Spinndüsen 2.1, 2.2 und 2.3 ist ein Kühlschacht 5 und ein sich unmittelbar an dem Kühlschacht 5 anschließender Fallschacht 6 angeordnet. Der Kühlschacht 5 ist mit einem Kühlstromerzeuger 41 verbunden, durch welchen ein quer zum Kühlschacht 5 strömender Kühlluftstrom erzeugbar ist.The melt spinning device has a plurality of spinnerets 2.1, 2.2 and 2.3, which are arranged on an underside of a heated spinneret 1. The spinnerets 2.1 and 2.2 and 2.3 is associated with a
Unterhalb des Fallschachtes 6 ist eine Präparationseinrichtung 7 sowie mehrere Behandlungseinrichtungen 15.1 und 15.2 angeordnet. Die Ausbildung der Behandlungseinrichtungen 15.1 und 15.2 ist abhängig von dem jeweils durch den Schmelzspinnprozess herzustellenden Fadentyp. So ist beispielsweise zur Herstellung von voll verstreckten Fäden (FDY) die zweite Behandlungseinrichtung 15.2 durch ein Streckwerk mit mehreren Galetteneinheiten (gestrichelt angedeutet) gebildet, um die Fäden zu verstrecken. Die erste Behandlungseinrichtung 15.1 könnte dabei als eine Tangeleinrichtung ausgebildet sein, um einen verbesserten Fadenschluss durch Verwirbelung der Filamentstränge zu erhalten.Below the
Am Ende weist die Schmelzspinnvorrichtung eine Aufwickeleinrichtung 16 auf, durch welche Spulen 17 an einer Spulspindel 18 gewickelt werden.At the end, the melt spinning device has a take-up
Im Betrieb werden mit der Schmelzspinnvorrichtung mehrere Filamentbündel 4.1, 4.2 und 4.3 parallel nebeneinander extrudiert. Hierzu wird eine Kunststoffschmelze unter Druck den Spinndüsen 2.1, 2.2 und 2.3 zugeführt. Die Spinndüsen 2.1, 2.2 und 2.3 weisen auf ihrer Unterseite eine Düsenplatte auf, in denen eine Vielzahl von Düsenbohrungen enthalten sind. Durch jede der Düsenbohrungen wird ein Filamentstrang extrudiert. Die Anzahl der Filamentstränge pro Spinndüse 2.1, 2.2 und 2.3 bilden jeweils ein Filamentbündel. So wird das Filamentbündel 4.1 durch die extrudierten Filamentstränge der Spinndüse 2.1 gebildet. Die Filamentstränge der Filamentbündel 4.1, 4.2 und 4.3 werden über Abzugorgane in den Behandlungseinrichtungen 15.1 oder 15.2 von den Spinndüsen 2.1, 2.2 und 2.3 abgezogen. Dabei durchlaufen die Filamentstränge der Filamentbündel 4.1, 4.2 und 4.3 den Kühlschacht 5 und den Fallschacht 6, wobei in dem Kühlschacht 5 ein Kühlmedium auf die Filamentstränge einwirkt. Am Ende des Fallschachtes 6 werden die Filamentbündel 4.1, 4.2 und 4.3 durch eine Präparationseinrichtung 7 geführt, um die einzelnen Filamentstränge der Filamentbündel 4.1, 4.2 und 4.3 zu benetzen. Dabei entsteht ein Zusammenschluss der Filamentstränge der Filamentbündel 4.1, 4.2 und 4.3, so dass sich jeweils ein multifiler Faden 8.1, 8.2 und 8.3 ausbildet. Jede der Filamentbündel 4.1, 4.2 und 4.3 wird somit nach der Präparationseinrichtung 7 als Faden 8.1, 8.2 und 8.3 den anschließenden Behandlungseinrichtungen 15.1 und 15.2 zugeführt. Am Ende der Behandlung werden die Fäden 8.1, 8.2 und 8.3 zu jeweils einer Spule 17 in der Aufwickeleinrichtung 16 gewickelt. Die Aufwickeleinrichtung 16 weist hierzu eine Changiereinrichtung (nicht näher dargestellt) sowie eine am Umfang der Spulen 17 anliegende Andrückwalze 19 auf, um die Fäden 8.1, 8.2 und 8.3 auf die Spulen 17 zu legen.In operation, a plurality of filament bundles 4.1, 4.2 and 4.3 are extruded parallel side by side with the melt spinning device. For this purpose, a plastic melt is fed under pressure to the spinnerets 2.1, 2.2 and 2.3. The spinnerets 2.1, 2.2 and 2.3 have on their underside a nozzle plate in which a plurality of nozzle bores are included. Through each of the nozzle bores a filament strand is extruded. The number of filament strands per spinneret 2.1, 2.2 and 2.3 each form a filament bundle. Thus, the filament bundle 4.1 is formed by the extruded filament strands of the spinneret 2.1. The filament strands of the filament bundles 4.1, 4.2 and 4.3 are withdrawn via extraction elements in the treatment devices 15.1 or 15.2 of the spinnerets 2.1, 2.2 and 2.3. The filament strands of the filament bundles 4.1, 4.2 and 4.3 pass through the cooling
Bevor der Spinnprozess der zuvor beschriebenen Art durchgeführt werden kann, müssen die Fäden in den Einrichtungen der Schmelzspinnvorrichtung eingelegt werden. Um das Erstanlegen der Fäden möglichst schnell und auf einfache Art und Weise durch eine Bedienperson ausführen zu können, weist die Schmelzspinnvorrichtung Hilfsmittel auf, die nachfolgend näher beschrieben sind. Im Fadenlauf ist der Präparationseinrichtung 7 ein Hilfsführungsmittel 9 zugeordnet. Das Hilfsführungsmittel 9 wird in diesem Ausführungsbeispiel durch eine Führungsstange 10 gebildet, die sich parallel zu einer Fadenlaufebene erstreckt, in welcher die Filamentbündel 4.1, 4.2 und 4.3 geführt sind. An der Führungsstange 10 greift ein Aktor 11 an, durch welchen die Führungsstange 10 zwischen einer Auslenkposition und einer Betriebsposition hin und her verstellbar ist.Before the spinning process of the type described above can be carried out, the threads must be inserted in the devices of the melt spinning device. In order to be able to carry out the initial application of the threads as quickly and easily as possible by an operator, the melt spinning device has aids which are described in more detail below. In the yarn path of the
Im Fadenlauf ist der Präparationseinrichtung 7 ein Anlegehilfsmittel 12 nachgeordnet. Das Anlegehilfsmittel 12 weist mehrere Separierfadenführer 13.1, 13.2 und 13.3 auf. Die Separierfadenführer 13.1, 13.2 und 13.3 sind in der Fadenlaufebene nebeneinander mit Abstand angeordnet. Der Fadenabstand zwischen den Separierfadenführern 13.1, 13.2 und 13.3 ist hierbei wesentlich kleiner als der Abstand der Filamentbündel 4.1, 4.2 und 4.3 während des Extrudierens durch die Spinndüsen 2.1, 2.2 und 2.3. Der Abstand der Filamentbündel 4.1, 4.2 und 4.3 während des Extrudierens ist gleich einem Mittenabstand M zwischen den Spinndüsen 2.1, 2.2 und 2.3. Der Mittenabstand M bezeichnet hierbei den Abstand der Mittelachsen der Spinndüsen. Der Mittenabstand M wird auch als Düsenteilung bezeichnet. Der Mittenabstand der Filamentbündel 4.1, 4.2 und 4.3 ist wesentlich größer als der Abstand zwischen den Fäden während der Behandlung. Der Abstand zwischen den Fäden 8.1, 8.2 und 8.3 während der Behandlung wird hier als Behandlungsabstand B bezeichnet. Der Behandlungsabstand B liegt vorzugsweise in einem Bereich von 8 mm bis 30 mm.In the yarn path of the preparation device 7 a

Den Separierfadenführern 13.1, 13.2 und 13.3 ist ein Führungsblech 14 zugeordnet. Das Zusammenwirken der Separierfadenführer 13.1, 13.2 und 13.3 mit dem Führungsblech 14 wird nachfolgend unter Bezug auf die Fig. 1.3 erläutert.The Separierfadenführern 13.1, 13.2 and 13.3 is assigned a
Das den Separierfadenführern 13.1, 13.2 und 13.3 zugeordnete Führungsblech 14 weist zu jedem der Separierfadenführern 13.1, 13.2 und 13.3 jeweils einen Führungsschlitz 21.1, 21.2 und 21.3 auf. Ein Ende der Führungsschlitze 21.1, 21.2 und 21.3 mündet unmittelbar in Höhe unmittelbar vor den Separierfadenführern 13.1, 13.2 und 13.3. Ein gegenüberliegendes Ende der Führungsschlitze 21.1, 21.2 und 21.3 mündet an einer Anlegekante 20, die mit Abstand zu den Separierfadenführern 13.1, 13.2 und 13.3 angeordnet ist. Die Mündungsenden der Führungsschlitze 21.1, 21.2 und 21.3 an der Anlegekante 20 weisen dabei einen Fadenabstand auf, der vorzugsweise kleiner dem Fadenabstand der Separierfadenführer 13.1, 13.2 und 13.3 ausgebildet ist.The
Zum Erstanlegen der Filamentbündel 4.1, 4.2 und 4.3 werden diese zunächst nach dem Anspinnen durch die Spinndüsen 2.1, 2.2 und 2.3 gemeinsam durch eine Absaugeinrichtung 23 aufgenommen. Die Absaugeinrichtung 23, die vorzugsweise durch eine manuell geführte Saugpistole gebildet ist, weist eine Saugöffnung 22 auf, wie in den
Um die Filamentbündel 4.1, 4.2 und 4.3 voneinander zu trennen, wird nun die Absaugeinrichtung 23 kurz unterhalb des Führungsbleches 14 in Richtung der Anlegkante 20 geführt. Da die Filamentbündel 4.1, 4.2 und 4.3 nach wie vor unmittelbar durch die Absaugeinrichtung 23 von den Spinndüsen 2.1, 2.2 und 2.3 abgezogen werden, vergrößert sich der Abstand zwischen den Filamentbündeln mit zunehmendem Abstand zu der Saugöffnung 22. Durch Bewegung der Absaugeinrichtung 23 gegen die Anlegkante 20 lässt sich eine Aufteilung der Filamentbündel 4.1, 4.2 und 4.3 derart vornehmen, so dass jedes der Filamentbündel 4.1, 4.2 und 4.3 in einen der Führungsschlitze 21.1, 21.2 und 21.3 einfällt und bei weiterer Bewegung der Absaugeinrichtung 23 selbsttätig in die Separierfadenführer 13.1, 13.2 und 13.3 eingefädelt werden. Nun sind die Filamentbündel 4.1, 4.2 und 4.3 voneinander getrennt, so dass sich die Fäden 8.1, 8.2 und 8.3 durch die Absaugeinrichtung 23 manuell auf einfache Art und Weise in die nachfolgenden Einrichtungen eingelegt werden können. Die Separierfadenführer 13.1, 13.2 und 13.3 stellen somit einen Konvergenzpunkt dar, in welchem die Filamentstränge jedes der Filamentbündel 4.1, 4.2 und 4.3 zu einem Faden zusammengeführt werden. Unmittelbar nach der Separierung der Filamentbündel 4.1, 4.2 und 4.3 wird das Hilfsführungsmittel 9 in eine Betriebsposition verschwenkt, so dass die Filamentbündel 4.1, 4.2 und 4.3 selbsttätig in die Präparationseinrichtung 7 eingeführt werden. Hierzu wird der Aktor 11 aktiviert, so dass die Führungsstange 10 aus der Auslenkposition in die Betriebsposition geführt wird. Diese Situation ist in

Als weiteren Unterschied werden die Filamentbündel 4.1, 4.2 und 4.3 in einer Spinnebene zu den Fäden 8.1, 8.2 und 8.3 geführt. Die Behandlung der Fäden 8.1, 8.2 und 8.3 erfolgt jedoch an einer um 90° versetzten Behandlungsebene, so dass zwischen der Behandlungseinrichtung 15 und der Präparationseinrichtung 7 eine Drehung der Fadenschar aus einer Spinnebene in eine Behandlungsebene erfolgt. Hierzu ist zwischen der Präparationseinrichtung 7 und der Behandlungseinrichtung 15 eine Tangelvorrichtung 35 und ein Stiftfadenführer 30 angeordnet. Die Tangelvorrichtung 35 weist pro Faden einen Behandlungskanal 34 auf (
Zum Präparieren der in den Spinndüsen 2.1 bis 2.3 abgezogenen Filamentbündel 4.1, 4.2 und 4.3 weist die Präparationseinrichtung 7 mehrere den Filamentbündel 4.1, 4.2 und 4.3 zugeordnete Fadenölungsmittel 24.1, 24.2 und 24.3 auf. Den Fadenölungsmitteln 24.1 bis 24.3 sind im Fadenlauf jeweils ein Gegenfadenölungsmittel 31.1 bis 31.3 derart nachgeordnet, so dass sich die Fadenölungsmittel 24.1 bis 24.3 und die Gegenfadenölungsmittel 31.1 bis 31.3 mit ihren Fadenkontaktflächen gegenüberstehen.

Zum Erstanlegen der Filamentbündel 4.1 bis 4.3 ist der Präparationseinrichtung 7 ein Hilfsführungsmittel 9 zugeordnet. Das Hilfsführungsmittel 9 ist durch eine erste Umlenkstange 25.1 und eine zweite Umlenkstange 25.2 gebildet. Die erste Umlenkstange 25.1 ist den Fadenölungsmitteln 24.1 bis 24.3 zugeordnet, wobei die Umlenkstange 25.1 sich parallel zu den in einer Ebene angeordneten Fadenölungsmitteln 24.1 bis 24.3 erstreckt. Die zweite Umlenkstange 25.2 ist den Gegenfadenölungsmitteln 31.1 bis 31.3 zugeordnet. Die Umlenkstangen 25.1 und 25.2 werden auskragend an einem Schwenkarm 26 gehalten. Der Schwenkarm 26 ist um eine Schwenkachse 27 drehbar gelagert. Die Drehbewegung des Schwenkarmes 26 lässt sich dabei durch einen Drehaktor 28 ausführen. Durch die Bewegung des Schwenkarmes 26 können die Umlenkstangen 25.1 und 25.2 zwischen einer Auslenkstellung und einer Betriebsstellung hin und her verstellt werden.For first application of the filament bundles 4.1 to 4.3, the

Die erfindungsgemäße Spinnvorrichtung sowie das erfindungsgemäße Verfahren zum Anlegen multifiler Fäden wurde anhand einiger Ausführungsbeispiele erläutert. Hierbei können die für das Verfahren wesentlichen Vorrichtungsteile in jeder zur Herstellung von multifilen Fäden geeigneten Schmelzspinnvorrichtungen eingesetzt werden. So ist die erfindungsgemäße Schmelzspinnvorrichtung geeignet, um textile, technische oder gekräuselte multifile Fäden herzustellen. Als Fadentyp können somit FDY, POY, HOY oder BCF Monocolor/Multicolor hergestellt werden. Durch die der Präparationseinrichtung nachgeordneten Separierung lässt sich die Bedienung zum Anlegen der Filamentbündel von einer Ebene her durch eine Bedienperson ausführen. Durch die Verlagerung des Konvergenzpunktes der Filamentbündel hin zur Behandlungseinrichtung ermöglicht eine sehr geringe Bauhöhe und kompakte Bauart der erfindungsgemäßen Schmelzspinnvorrichtung. Die Ausbildung der Hilfsführungsmittel und der Anlegehilfsmittel ist hierbei ebenfalls beispielhaft. Grundsätzlich können als Hilfsführungsmittel jegliche fadenführende Elemente verwendet werden, die ein Auslenken und Einfädeln der Filamentbündel in einer Präparationseinrichtung ermöglichen. Ebenso ist die Anzahl der Fäden in den dargestellten Ausführungsbeispielen beispielhaft und nicht auf die erfindungsgemäße Schmelzspinnvorrichtung beschränkt.The spinning device according to the invention and the inventive method for applying multifilament threads has been explained with reference to some embodiments. In this case, the device parts which are essential for the method can be used in any melt spinning device suitable for the production of multifilament threads. Thus, the melt spinning device according to the invention is suitable for producing textile, technical or crimped multifilament yarns. As thread type FDY, POY, HOY or BCF Monocolor / Multicolor can be produced. By separating the preparation device downstream, the operation for applying the filament bundles from one plane can be carried out by an operator. By shifting the point of convergence of the filament bundles towards the treatment device, a very small overall height and compact design of the inventive melt spinning device are possible. The design of the auxiliary guide means and the landing aids is also exemplary here. In principle, any thread-guiding elements which make it possible to deflect and thread the filament bundles in a preparation device can be used as auxiliary guiding means. Likewise, the number of threads in the illustrated embodiments is exemplary and not limited to the melt spinning device according to the invention.
