Das Lieferwerk besteht aus zwei Galetten, die von den Fäden teilumschlungen sind. Dabei wird in den Fäden oberhalb der Galetten eine Fadenzugkraft aufgebaut, die ein Verstrecken der Fäden bewirkt. Die Fadenzugkraft, mit der die Fäden aufgewickelt werden, ist geringer als die zur Verstreckung aufgebaute Fadenzugkraft.Such a method and such devices are from DE 42 03 076 known. Here, the threads by means of a delivery plant withdrawn from the spinning zone at high take-off speed. The The delivery plant consists of two godets, which are partially wrapped by the threads are. There is a thread tension in the threads above the godets built up, which causes the threads to stretch. The thread tension, with the thread to be wound on is less than that for drawing built thread tension.

Bei dem bekannten Verfahren erfolgt ein Fadenzugkraftsabbau, indem das Lieferwerk mit einer Umfangsgeschwindigkeit angetrieben wird, die größer ist als die Fadenauflaufgeschwindigkeit. Somit wird ein für die Aufwicklung niedriges Fadenzugkraftniveau bereits unmittelbar nach Ablauf von der letzten Galette eingestellt. Nach Ablauf von der Galette werden die Fäden zu den einzelnen Aufwickelstellen einer Aufwickeleinrichtung geführt.In the known method, thread tension is reduced by the Delivery plant is driven at a peripheral speed that is greater is than the thread take-up speed. Thus, one for the Rewinding of a low level of thread tension immediately after expiry set by the last godet. After the expiry of the godet the threads to the individual winding positions of a winding device guided.

Hierbei tritt nun das Problem auf, daß jeder Faden eine vom Fadenlauf abhängige spezifische Fadenzugkraft aufweist. Bereits beim Einlaufen in das Lieferwerk besitzen die Fäden aufgrund einer mehr oder weniger starken Umlenkung nach Austritt aus der Spinnzone unterschiedliche Fadenzugkräfte. Insbesondere bei Spinnanlagen, bei denen eine Mehrzahl von Fäden parallel in der Spinnzone gleichzeitig ersponnen werden, erfolgt vor dem Auflaufen auf das Lieferwerk ein Zusammenraffen sowie nach Verlassen des Lieferwerks ein Auseinanderspreizen der Fäden, um zu der jeweiligen Aufwickelposition geführt zu werden. Hieraus resultieren erhebliche Fadenzugkraftsschwankungen zwischen den einzelnen Aufwickelpositionen.
Derartige Unterschiede in den Fadenzugkräften führt in den Aufwickelpositionen zu Spulen, die in ihrer Qualität voneinander sehr abweichen.
The problem now arises here that each thread has a specific thread tensile force which is dependent on the thread run. When entering the delivery plant, the threads have different thread tensile forces due to a more or less strong deflection after exiting the spinning zone. In spinning machines in particular, in which a plurality of threads are spun simultaneously in the spinning zone, the threads are gathered together before they come into contact with the delivery plant and the threads are spread apart after leaving the delivery plant in order to be guided to the respective winding position. This results in considerable thread tension fluctuations between the individual winding positions.
Such differences in the thread tensile forces in the winding positions lead to bobbins that differ greatly in quality.

Aus der PCT-Patentanmeldung WO 96/09425 sind desweiteren ein Verfahren und eine Vorrichtung bekannt, bei welcher vor der Aufwickeleinrichtung zwei lange Galetten angeordnet sind, die einen parallelen Fadenlauf ermöglichen. Bei Spinnvorrichtungen mit acht und mehr Fäden, die gleichzeitig gesponnen werden, müssen demnach Galetten mit einer Länge von über 120 cm eingesetzt werden. Um die Fäden anlegen zu können, sind die Galetten nur einseitig auskragend an einem Träger gelagert. Hieraus folgt, daß derartig lange Galetten nur bei einer mittleren Geschwindigkeit des Fadens einsetzbar sind. Bei Fadengeschwindigkeiten von größer 6.000 m/min und einem Galettendurchmesser im Bereich von 100 bis 150 mm müssen die Galetten mit bis zu 20.000 U/min betrieben werden was erhebliche Standzeitprobleme mit sich bringt.PCT patent application WO 96/09425 also includes a Method and an apparatus known in which in front of the winding device two long godets are arranged, one parallel Allow thread running. For spinning devices with eight or more threads, which are spun at the same time must therefore have godets with one Length of over 120 cm can be used. To put the threads on can, the godets are only cantilevered on one support stored. From this it follows that such long godets only for a medium one Speed of the thread can be used. At thread speeds greater than 6,000 m / min and a godet diameter in the range of The godets have to operate from 100 to 150 mm at up to 20,000 rpm become what brings significant downtime problems.

Eine Vorrichtung zum Texturieren eines einzelnen Fadens ist in der Patentschrift US 3,743,202 beschrieben. Dabei wird der Faden mittels eines ersten Lieferwerkes von einer Vorlagespule abgezogen. Zum Aufbau einer Fadenspannung ist zwischen der Vorlagespule und dem ersten Lieferwerk eine Fadenbremse angeordnet. Der Fadenspannungsaufbau mittels der dargestellten Fadenbremse kann jedoch zu einer Klemmung des Fadens führen, so daß dieser beschädigt wird. Mittels eines zweiten Lieferwerkes wird der Faden verstreckt und zu einer Aufwickeleinrichtung geführt, wobei zwischen dem zweiten Lieferwerk und der Aufwickeleinrichtung ein Fadenspannungsmesser angeordnet ist, der zur Regelung der Aufwickelgeschwindigkeit dient. Die offenbarte Vorrichtung stellt eine selbständige Einheit dar, die nicht für eine parallele Bearbeitung mehrerer Fäden geeignet ist.A device for texturing a single thread is in the patent US 3,743,202. The thread is pulled by means of a first Subtracted from a supply spool. To build up a thread tension is a thread brake between the supply spool and the first delivery plant arranged. The thread tension build-up by means of the shown However, thread brake can lead to a clamping of the thread, so that this is damaged. The thread is drawn by means of a second delivery unit and led to a winding device, between the second delivery unit and the winding device is arranged a thread tension meter is used to control the winding speed. The device disclosed represents an independent unit, not for parallel processing several threads is suitable.

Demgemäß ist es Aufgabe der Erfindung, ein Verfahren und Vorrichtungen zum Spinnen und Aufwickeln von endlosen Fäden zu schaffen, bei dem die Fäden mit einer vorwählbaren Fadenzugkraft in jeder Wickelstelle und einer hohen Fadengeschwindigkeit aufgewickelt werden. Accordingly, it is an object of the invention, a method and Devices for spinning and winding endless threads create in which the threads with a preselectable thread tension in every winding point and a high thread speed become.

Die Lösung der Aufgabe ergibt sich mit einem Verfahren mit den Merkmalen des Anspruchs 1, mit einer Spinnvorrichtung mit den Merkmalen des Anspruchs 12 und mit einer Aufwickeleinrichtung mit den Merkmalen des Anspruch 30.The problem is solved with a method using the Features of claim 1, with a spinning device with the Features of claim 12 and with a winding device with the features of claim 30.

Vorteilhafte Ausgestaltungen des Verfahrens und der Vorrichtungen sind in den jeweiligen Unteransprüchen angegeben.Advantageous embodiments of the method and the devices are shown in the respective subclaims.

Die Erfindung bietet den Vorteil, daß die individuellen Einflüsse auf die Fadenzugkraft eines Fadens, die vom Spinnen bis zum Aufwickeln, wie z.B. bei der Kühlung, der Präparation, der Tangelung, dem Aufheizen oder der Fadenführung, auftreten, eliminiert werden können. An jedem Faden kann unabhängig von den benachbarten Fäden eine durch das dem Faden zugeordneten Lieferwerk bestimmte Fadenzugkraft eingestellt werden. Dazu werden die Lieferwerke durch angetriebene oder nichtangetriebene Rollen gebildet, die vom Faden teilumschlungen werden. Dabei wird jeder der Fäden zur Fadenspannungsbehandlung durch ein separates Lieferwerk von mehreren parallel angeordneten Lieferwerken geführt, wobei die Lieferwerke jeweils im Fadenlauf des zu behandelnden Fadens angeordnet sind, so daß jeder der Fäden bei Eintritt in die Aufwickelzone eine durch das dem Faden zugeordnete Lieferwerk bestimmte Fadenzugkraft aufweist. Insbesondere zum Aufwickeln läßt sich der Faden mit der einen optimalen Spulenaufbau bewirkenden Fadenzugkraft aufspulen.
Beispielsweise bei der Herstellung von gefärbten Fäden in unterschiedlichen Farben haben die Fäden unterschiedliche Eigenschaften; die sich auch bei Aufwickeln in unterschiedlichen Spulen auswirken. Durch das erfindungsgemäße Verfahren können jedoch in jeder Wickelstelle gleiche Spulenqualitäten hergestellt werden.
The invention offers the advantage that the individual influences on the thread tension of a thread, which occur from spinning to winding, such as during cooling, preparation, threading, heating or thread guidance, can be eliminated. A thread tension determined by the delivery mechanism assigned to the thread can be set on each thread independently of the neighboring threads. For this purpose, the delivery mechanisms are formed by driven or non-driven rollers, which are partially wrapped in the thread. Each of the threads for thread tension treatment is guided by a separate feed mechanism from a plurality of feed mechanisms arranged in parallel, the feed mechanisms being arranged in each case in the thread path of the thread to be treated, so that each of the threads has a thread tension determined by the feed mechanism assigned to the thread when it enters the winding zone having. In particular for winding, the thread can be spooled with the thread tensile force which brings about an optimal bobbin build-up.
For example, in the manufacture of colored threads in different colors, the threads have different properties; which also have an effect on winding in different bobbins. However, the same coil qualities can be produced in each winding station by the method according to the invention.

Bei der Herstellung von Fäden mit im wesentlichen gleichen physikalischen Eigenschaften wird angestrebt, daß die Fäden mit gleicher Fadenspannung aufgewickelt werden. Durch eine besonders vorteilhafte Weiterbildung des erfindungsgemäßen Verfahrens läßt sich dieses Problem lösen. In jeder Wickelstelle kann somit eine Spule mit gleichem Wicklungsaufbau und gleicher Packungsdichte gewickelt werden.When producing threads with essentially the same physical Characteristics is aimed at that the threads with the same Thread tension can be wound up. Through a particularly advantageous This problem can be further developed in the method according to the invention to solve. A coil with the same can therefore be used in each winding station Winding structure and the same packing density.

Eine besonders vorteilhafte Verfahrensvariante ermöglicht, daß die Fäden mit hoher Fadenzugkraft bis kurz vor Eintritt in die Aufwickelzone geführt werden. Dadurch wird ein sicherer Galettenbetrieb zum Verstrecken des Fadens gewährleistet, wobei beim Ablauf von der Galette keine Gefahr der Wicklerbildung besteht.A particularly advantageous process variant enables the threads with high thread tension until shortly before entering the winding zone be performed. This makes safe godet operation Stretching of the thread ensures that the godet runs off there is no risk of winder formation.

Durch die Steuerung oder Regelung der Lieferwerke in Abhängigkeit von der gemessenen Fadenzugkraft im Fadenlauf vor den Lieferwerken besteht die Möglichkeit, direkt auf Veränderungen während des Prozesses zu reagieren. Die Steuerung oder Regelung kann mit Hilfe der veränderbaren Umfangsgeschwindigkeit oder der veränderbaren Fadenumschlingung durchgeführt werden.By controlling or regulating the delivery plants depending on the measured thread tension in the thread run in front of the supplying plants the ability to jump straight to changes during the process react. The control or regulation can be changed with the help of Peripheral speed or the variable thread wrap be performed.

Die Weiterbildung des Verfahrens dadurch, daß die herrschende Fadenzugkraft im Fadenlauf hinter dem Lieferwerk gemessen wird, besitzt den Vorteil, daß ebenfalls die aus der Aufwicklung hervorgehenden Fadenzugkraftsänderungen wie z.B. der Changierung auszugleichen. Insbesondere ist es auch möglich, den Fadenzugkraftsabfall beim Fadenwechsel von der vollen Spule auf die Leerhülse auszugleichen. Hierbei wird, wie in der DE 40 33 960 beschrieben, eine Fadenbremse dazu genutzt, eine höhere Fadenzugkraft aufzubauen. Dadurch wird eine hohe Laufsicherheit und Fangsicherheit beim Spulenwechsel erreicht.The further development of the process in that the prevailing Thread tension is measured in the thread path behind the delivery unit the advantage that also the resulting from the winding Thread tension changes such as to compensate for the change. In particular, it is also possible to decrease the thread tension when Compensate for thread changes from the full bobbin to the empty tube. Here, as described in DE 40 33 960, a thread brake used to build up a higher thread tension. This will make one high running safety and catching safety when changing bobbins.

Um den Aufwand zur Verstellung der einzelnen Lieferwerke gering zu halten, ist es von Vorteil, die Lieferwerke in Abhängigkeit von der Fadenzugkraft einer Referenzstelle zu steuern. In dem Fall, daß die Fäden beim Ablauf von einer vor der Aufwickelzone angeordneten Galette auseinandergespreizt werden, um zu den einzelnen Aufwickelstellen zu gelangen, weisen die Fäden, die außen liegen und somit die stärkste Umlenkung erhalten, einen im Vergleich zu den mittleren Fäden ein höheres Fadenzugkraftsniveau auf. Hierbei ist es zweckmäßig, die Referenzmeßstelle in den Fadenlauf eines der mittleren Fäden zu legen. In order to minimize the effort for adjusting the individual delivery plants hold, it is advantageous to depend on the supplying plants To control the thread tension of a reference point. In the event that the Threads when a godet is arranged in front of the winding zone be spread apart to reach the individual winding stations get the threads that are on the outside and thus the strongest Receive redirection, one compared to the middle threads higher thread tension level. It is advisable to use the reference measuring point to place one of the middle threads in the thread path.

Das Verfahren kann jedoch auch derart modifiziert werden, daß ein bestimmtes Fadenzugkraftsniveau vorgegeben wird, um etwa eine bestimmte Qualität der Aufspulung zu erhalten.However, the method can also be modified such that a certain thread tension level is specified by about one to obtain certain quality of the winding.

Die Variante, bei der die Lieferwerke durch zwei angetriebene Rollen gebildet wird, die vom Faden S-förmig umschlungen sind, ist insbesondere für den Fadenzugkraftsabbau geeignet, so daß die Fadenzugkraft im Fadenlauf hinter den Lieferwerken auf einem geringeren Nieveau liegt als die Fadenzugkraft vor dem Lieferwerk. Beide Förderrollen können auch derart zueinander angeordnet sein, daß sie vom Faden Z-förmig umschlungen werden.The variant in which the delivery plants are driven by two driven rollers is formed, which are wrapped in an S-shaped thread, is in particular suitable for thread tension reduction, so that the thread tension in Thread run behind the delivery plants is at a lower level than the thread tension in front of the delivery plant. Both conveyor rollers can too be arranged to each other so that they are Z-shaped from the thread are embraced.

Die Verfahrensvariante, bei der die Lieferwerke durch zwei nicht angetriebene Rollen gebildet wird, die vom Faden S-förmig umschlungen sind, ist insbesondere zu einer Erhöhung der Fadenzugkraft in der Aufwickelzone geeignet.The process variant in which the supplying plants do not have two driven rollers is formed, which is wound in an S-shaped thread are, in particular to increase the thread tension in the Suitable winding area.

Das erfindungsgemäße Verfahren ist geeignet, um in einem Arbeitsgang zu voll- oder teilverstreckten Fäden (FOY oder POY) zu gelangen. Hierbei können alle Arten von Fadenmaterialien wie Polypropylen, Polyester, Polyamid und Viskose vorteilhaft nach diesem Verfahren gesponnen und aufgewickelt werden.The method according to the invention is suitable for in one operation fully or partially drawn threads (FOY or POY). in this connection can handle all types of thread materials such as polypropylene, polyester, Polyamide and viscose advantageously spun and by this method be wound up.

Die Erfindung bietet weiterhin den Vorteil, daß die Messung der Fadenzugkraft gleichzeitig zur Überwachung der Fadenqualität dient, wie in der EP 0644 282 beschrieben. Dabei könnten die Meßsignale, die insbesondere im Fadenlauf vor dem Lieferwerk gewonnen werden, dazu dienen, den tatsächlichen Prozeßverlauf in der Spinnzone und in der Streckzone zu beeinflussen. The invention also has the advantage that the measurement of Thread tension also serves to monitor the thread quality, such as described in EP 0644 282. The measurement signals could especially in the thread run in front of the delivery plant serve the actual process in the spinning zone and in the To influence the stretch zone.

Eine besonders vorteilhafte Weiterbildung der Vorrichtung sieht vor, daß die Lieferwerke mit dem Maschinengestell der Aufwickeleinrichtung verbunden sind. Somit läßt sich eine Fadenzugkraft in dem Faden direkt vor Einlauf in den Kopffadenführer der Aufwickeleinrichtung einstellen. Desweiteren läßt sich die Bedienbarkeit der Lieferwerke mit der Bedienung der Aufwickeleinrichtung verbinden. Eine für die Bedienung der Aufwickeleinrichtung zuständige Person könnte über die Bedienung der Lieferwerke direkt Einfluß nehmen auf die Qualität der gewickelten Spulen.A particularly advantageous development of the device provides that the delivery plants with the machine frame of the rewinder are connected. Thus, a thread tension can be directly in the thread adjust before entering the winding head of the take-up device. Furthermore, the operability of the delivery plants with the Connect operation of the rewinder. One for the operation of the Rewinder responsible person could operate the Delivery plants have a direct influence on the quality of the wound coils.

Durch die Anordnung der Lieferwerke unmittelbar vor dem Kopffadenführer können sich zudem die aus der Changierbewegung resultierenden Fadenschwingungen nur bis zum Lieferwerk fortpflanzen. Es hat sich bereits gezeigt, daß ein Lieferwerk mit einer angetriebenen vom Faden teilumschlungenen Förderrolle zur Qualitätsverbesserung des gewickelten Fadens, insbesondere der Einfärbbarkeit, geführt hat. Die vom Faden umschlungene Förderrolle wird hierbei mit einer Umfangsgeschwindigkeit angetrieben, die größer ist als die Fadenlaufgeschwindigkeit. Hierüber wird zwischen dem Faden und dem Umfang der Förderrolle ein Schlupf erzeugt, der zum Abbau einer Fadenzugkraft führt. Der Antrieb der Förderrolle könnte jedoch auch derart erfolgen, daß die Umfangsgeschwindigkeit der Förderrolle kleiner ist als die Fadenlaufgeschwindigkeit. Damit ergeben sich Bremseffekte, die eine Fadenspannungserhöhung bei der Aufwicklung bewirken.By arranging the delivery mechanisms directly in front of the head thread guide can also result from the traversing movement Propagate thread vibrations only up to the delivery plant. It has already shown that a delivery plant with a driven by the thread partially wrapped conveyor role to improve the quality of the wound Fadens, especially the colorability. The thread wrapped conveyor roller is at a peripheral speed driven, which is greater than the thread speed. About this creates a slip between the thread and the circumference of the conveyor roller, which leads to the reduction of thread tension. The drive of the However, the conveyor roller could also be such that the peripheral speed the feed roller is less than the thread speed. This results in braking effects that increase the thread tension effect when winding up.

Eine weitere bevorzugte Variante wird durch ein Lieferwerk mit drei angetriebenen Förderrollen gebildet. Eine derartige Vorrichtung ist insbesondere zum Abbau von hohen Fadenzugkräften geeignet. Damit lassen sich Spulen bei sehr geringem Niveau der Fadenzugkraft herstellen. Another preferred variant is a supply plant with three driven conveyor rollers formed. Such a device is Particularly suitable for reducing high thread tension. In order to bobbins can be produced with a very low level of thread tension.

Um die Einstellung der Fadenzugkraft innerhalb des Lieferwerks zu beeinflussen, ist es von Vorteil, wenn zumindest eine der Rollen in den Fadenlauf ein- oder ausschwenkbar ausgeführt ist. Damit kann der Umschlingungswinkel an den Rollen und damit die Reibverhältnisse zwischen dem Faden und den jeweiligen Oberflächen der Förderrollen beeinflußt werden.To adjust the thread tension within the supplying plant too influence, it is advantageous if at least one of the roles in the Thread run is designed to swivel in or out. So that the Wrap angle on the rollers and thus the friction conditions between the thread and the respective surfaces of the conveyor rollers to be influenced.

Darüberhinaus besitzt die Spinnvorrichtung, bei welcher das Lieferwerk einen Zustand einnehmen kann, in dem die Fadenzugkraft nicht beeinflußt wird, den Vorteil, daß ein Anlegen der Fäden in die Lieferwerke auf einfache Weise durchführbar ist. Zur Unterstützung können dabei die Förderrollen eine am Umfang angebrachte Anlegeschräge aufweisen.In addition, the spinning device, in which the delivery plant can assume a state in which the thread tension does not affect is, the advantage that a threading in the supply plants is simple to carry out. To support you can Conveyor rollers have a bevel attached to the circumference.

Bei einer weiteren besonders vorteilhaften Weiterbildung der Erfindung werden die Förderrollen an dem Lieferwerk unabhängig voneinander angetrieben. Damit ergibt sich ein weiterer Parameter, um die Einstellung der Fadenzugkraft im Faden zu verändern. Die Rollen können hierbei mittels Einzelmotoren oder über Gruppenantriebe angetrieben werden. Der Antrieb über Einzelmotoren ist von Vorteil, wenn große Fadenzugkraftunterschiede in den einzelnen nebeneinander gesponnenen Fäden auftreten.In a further particularly advantageous development of the invention the conveyor rollers at the delivery plant are independent of each other driven. This gives another parameter to the setting to change the thread tension in the thread. The roles here driven by single motors or group drives. The Single motor drive is beneficial when large Differences in thread tension in the individual spun next to each other Threads occur.

Bei im wesentlichen parallelen Verlauf der Fäden zueinander lassen sich die Förderrollen benachbarter Lieferwerke bevorzugt durch einen Gruppenantrieb antreiben.With the threads running essentially parallel to one another, the conveyor rollers of neighboring supply plants preferably by one Drive group drive.

Bei der direkten Anbindung der Lieferwerke an die Aufwickeleinrichtung ist es besonders günstig, wenn die Lieferwerke in den Ablauf der Aufwickeleinrichtung integriert ist. Somit läßt sich beim Spulenwechsel die Lieferwerke direkt über das Steuergerät der Aufwickeleinrichtung derart ansteuern, daß beispielsweise beim Wechsel kein Verschlappen des Fadens eintritt.With the direct connection of the supplying plants to the winding device it is particularly favorable if the supplying plants are involved in the expiry of Rewinder is integrated. Thus, when changing the bobbin Delivery plants directly via the control unit of the winding device control that, for example, the thread does not sag when changing entry.

Durch die Steuerung oder Regelung der Lieferwerke in Abhängigkeit von der gemessenen Fadenzugkraft im Fadenlauf vor dem Lieferwerk besteht die Möglichkeit, direkt auf Veränderungen während des Prozesses zu reagieren.By controlling or regulating the delivery plants depending on the measured thread tension in the thread run in front of the delivery plant the ability to jump straight to changes during the process react.

In Fig. 1 ist schematisch eine Spinnvorrichtung zur Durchführung des erfindungsgemäßen Verfahrens dargestellt. Dem Spinnkopf 1 wird ein aufgeschmolzenes Polymer mittels eines Extruders zugeführt. Das Polymer wird sodann durch eine Spinnpumpe zu einer Spinndüse 3 geführt und über zahlreiche Düsen-bohrungen in der Spinndüse 3 zu einer Vielzahl von Filamenten gesponnen. Die Spinnanlage weist insgesamt vier Spinnstellen auf. Da jeder Faden einer Spinnstelle gleich behandelt wird, wird der Prozeß anhand eines Fadenlaufs beschrieben.In Fig. 1 is a spinning device for performing the represented method according to the invention. The spinning head 1 becomes a melted polymer fed by means of an extruder. The polymer is then passed through a spinning pump to a spinneret 3 and over numerous nozzle bores in the spinneret 3 to a variety spun from filaments. The spinning plant has a total of four Spinning on. Since every thread in a spinning station is treated equally, the process is described using a thread run.

Nachdem das Filamentbündel 4 aus der Spinndüse 3 ausgetreten ist, durchläuft das Filamentbündel 4 einen Kühlschacht 2. Hierbei wird vorzugsweise mit Blasluft das Filamentbündel 4 abgekühlt. Nach der Abkühlung wird das Filamentbündel 4 im Fadenführer 5 zu einem Faden 12 zusammengeführt. Der Faden 12 durchläuft anschließend eine Präparationseinrichtung 6, um einen Fadenschluß herzustellen. Die Präparationseinrichtung 6 könnte auch an die Stelle des Fadenführers 5 angeordnet werden: In diesem Fall-würde der Fadenführer 5 entfallen. Daran anschließend wird der Faden 12 in eine Verstreckzone geführt, die durch die Galetten 8 und 10 gebildet wird. Die Verstreckzone ist hierbei durch eine strichpunktierte Umrandung in der Fig. 1 gekennzeichnet. Da die Breite der Spinnzone der parallel nebeneinander angeordneten Spinnstellen größer ist als die Breite der Lauffläche der Galette 8, müssen die Fäden in Abhängigkeit von ihrer Lage mehr oder weniger stark zu jeweils einem Fadenführer 7 umgelenkt werden, um die Galetten 8 und 10 parallel zu durchlaufen. Die Galette 8 wird vom Galettenmotor 9 angetrieben. Die Galette 10 wird von dem Galettenmotor 11 angetrieben. Hierbei wird die Galette 10 mit einer höheren Umfangsgeschwindigkeit angetrieben als die Galette 8. Der Faden 12 umschlingt die Galetten 8 und 10 S- oder Z-förmig. Bei dieser Ausbildung der Verstreckzone ist die Galette 8 beheizt, um den Faden zu erwärmen.After the filament bundle 4 has emerged from the spinneret 3, the filament bundle 4 passes through a cooling shaft 2 preferably the filament bundle 4 is cooled with blowing air. After The filament bundle 4 becomes a thread in the thread guide 5 12 merged. The thread 12 then runs through Preparation device 6 to produce a thread closure. The Preparation device 6 could also replace thread guide 5 be arranged: In this case, the thread guide 5 would be omitted. Then the thread 12 is guided into a drawing zone, which is formed by the godets 8 and 10. The stretch zone is here characterized by a dash-dotted outline in FIG. 1. There the width of the spinning zone of the parallel arranged side by side Spinning positions is greater than the width of the tread of the godet 8, must the threads increase more or less depending on their location a thread guide 7 are deflected to the godets 8 and 10 to go through in parallel. The godet 8 is driven by the godet motor 9 driven. The godet 10 is driven by the godet motor 11. Here, the godet 10 with a higher peripheral speed driven as the godet 8. The thread 12 wraps around the godets 8 and 10 S or Z-shaped. In this configuration, the stretching zone is Galette 8 heated to heat the thread.

Zur Verstreckung und Fixierung des Fadens ist es jedoch auch möglich, zwischen der Präpariereinrichtung 6 und der Galette 8 eine Heizeinrichtung anzuordnen. Die Heizeinrichtung kann dabei als geradegestrecktes Heizrohr oder als Heizschiene ausgebildet sein.However, to stretch and fix the thread, it is also possible to between the preparation device 6 and the godet 8 one To arrange heating device. The heater can be as straight heating tube or be designed as a heating rail.

Nachdem der Faden von der Galette 10 abgelaufen ist, wird der Faden 12 vom Fadenführer 21 zu einem Kopffadenführer 14 geführt. Der ortsfeste Kopffadenführer 14 gehört zu einer von insgesamt vier Wickelstellen 41 einer Aufwickeleinrichtung. In jeder Wickelstelle 41 durchläuft der Faden eine Changiereinrichtung 15, die den Faden 12 im wesentlichen quer zu der Fadenlaufrichtung entlang eines Changierhubes hin- und herverlegt. Die Changiereinrichtung 15 kann als Flügelchangierung oder als Kehrgewinde-Wellenchangierung ausgeführt sein. Zwischen der Changiereinrichtung 15 und dem Kopffadenführer 14 bildet sich das sogenannte Changierdreieck aus. Der Faden läuft auf eine hinter der Changiereinrichtung angeordnete Andrückwalze 16 auf, die in dem Maschinengestell 20 drehbar gelagert ist. Die Andrückwalze 16 wird vom Faden teilumschlungen und danach auf die Spule 18 abgelegt. Die Spule 18 ist auf einer Spulspindel 17 aufgesteckt. Die Spulspindel 17 wird mittels des Spindelmotors 19 angetrieben. Der Spindelmotor 19 wird in Abhängigkeit von der Umfangsgeschwindigkeit der Andrückwalze derart geregelt, daß die Umfangsgeschwindigkeit der Spule stets konstant ist, so daß der Faden mit einer gleichbleibenden Aufwickelgeschwindigkeit aufgespult wird.After the thread has run off the godet 10, the thread 12 guided by the thread guide 21 to a head thread guide 14. The Fixed head thread guide 14 belongs to one of a total of four Winding points 41 of a winding device. In each winding station 41 the thread passes through a traversing device 15 which the thread 12 in essentially transverse to the thread running direction along a traversing stroke moved back and forth. The traversing device 15 can be used as Wing traversing or as a reversible thread shaft traversing. This is formed between the traversing device 15 and the head thread guide 14 so-called traverse triangle. The thread runs on one behind the Traversing device arranged pressure roller 16, which in the Machine frame 20 is rotatably mounted. The pressure roller 16 is from Partially wrapped thread and then placed on the spool 18. The sink 18 is placed on a winding spindle 17. The winding spindle 17 will driven by the spindle motor 19. The spindle motor 19 is in Dependence on the peripheral speed of the pressure roller in such a way regulated that the peripheral speed of the coil is always constant, so that the thread with a constant winding speed is wound up.

Da die Spulspindel 17 länger ist als die Galette 10, ist es erforderlich, daß die Fäden 12 nach Ablauf von der Galette 10 mehr oder weniger stark ausgelenkt werden, um in die jeweilige Aufwickelstelle parallel einzulaufen. Da sowohl die Zusammenführung der Fäden vor der Galette 8 als auch das Auseinanderführen der Fäden nach der Galette 10 nur mit Hilfe von Fadenführern 7 und 21 möglich ist, wird eine je nach Grad der Umlenkung abhängige Reibkraft in dem Faden 12 erzeugt. Somit werden in jedem Faden unterschiedliche Fadenzugkräfte aufgebaut. Für ein hochwertiges Garn ist es jedoch erforderlich, daß der Faden mit im wesentlichen konstanter Fadenzugkraft zu einer Spule gewickelt wird. Erfindungsgemäß durchläuft der Faden 12 jeweils ein Lieferwerk 13, deren Wirkungsweise später beschrieben wird. Die Lieferwerke 13 ist zwischen dem Fadenführer 21 und dem Kopffadenführer 14 angeordnet. In dem Lieferwerk 13 wird an dem Faden 12 eine Fadenzugkraft ab- oder aufgebaut. In der in Fig. 1 gezeigten Spinnanlage erfolgt ein Abbau der Fadenzugkraft. Hierbei ist die Einstellung der Lieferwerke 13 in jedem Fadenlauf so eingestellt, daß die Fäden im Fadenlauf hinter dem Lieferwerk 13 eine im wesentlichen gleiche Fadenzugkraft aufweisen. Daher ist der Spannungsabbau in den äußeren Fäden aufgrund der stärkeren Auslenkung höher als bei den mittleren Fäden. Jedes der Lieferwerke hat somit eine vom Fadenlauf abhängige vorgegebene Einstellung.Since the winding spindle 17 is longer than the godet 10, it is necessary that the threads 12 more or less after the end of the godet 10 be strongly deflected to parallel in the respective winding point einzulaufen. Since both the merging of the threads in front of the godet 8 and the spreading of the threads after the godet 10 only with Help from thread guides 7 and 21 is possible, depending on the degree the deflection dependent frictional force generated in the thread 12. Consequently different thread tensile forces are built up in each thread. For a high quality yarn, however, it is necessary that the thread with in substantially constant thread tension is wound into a bobbin. According to the invention, the thread 12 passes through a delivery mechanism 13, whose mode of operation will be described later. The delivery plants 13 is arranged between the thread guide 21 and the head thread guide 14. In the supply mechanism 13 is a thread tension on or off the thread 12 built up. In the spinning plant shown in Fig. 1, the Yarn tension. Here is the setting of the supply plants 13 in each Thread run adjusted so that the threads in the thread run behind the Delivery mechanism 13 have a substantially equal thread tension. Therefore, the tension release in the outer threads is due to the stronger Deflection higher than with the middle threads. Each of the delivery plants thus has a predefined setting that is dependent on the yarn path.

Mit dem in Fig. 1 beschriebenen Verfahren werden vorteilhaft POY-Game hergestellt. Hierbei ist es jedoch auch möglich, daß die Fäden direkt von der Aufwickelvorrichtung ohne Zwischenschaltung eines Streckwerkes (Galetten) aus der Spinnzone abgezogen werden. Der Aufbau der Spinnvorrichtung würde der Spinnvorrichtnng aus Fig. 1 ohne die strichpunktiert gekennzeichnete Streckzone entsprechen. Bevor die Fäden in die Aufwickeleinrichtungen einlaufen, passieren sie die jeweiligen Lieferwerke zur Einstellung der Fadenzngkraft. Die Fäden werden dabei vorteilhaft parallel aus der Spinnzone bis zu den Lieferwerken geführt. With the method described in FIG. 1, POY games are advantageous manufactured. Here, however, it is also possible that the threads directly from the winding device without the interposition of a drafting system (Godets) are withdrawn from the spinning zone. The structure of the Spinning device would the Spinnvorrichtnng from Fig. 1 without the the stretch zone marked with dash-dotted lines. Before the threads in the take-up devices run in, they pass through the respective Supplying units for setting the thread tension. The threads are there advantageously guided in parallel from the spinning zone to the delivery plants.

In Fig. 2 ist eine Spinnvorrichtung gezeigt, die speziell zur Herstellung von FDY-Garnen geeignet ist. Da der Verfahrensablauf vom Spinnen bis zum Aufwickeln ähnlich dem in Fig. 1 gezeigten Spinnverfahren ist, werden an dieser Stelle nur die Abweichungen gegenüber dem Verfahren und der Vorrichtung nach Fig. 1 beschrieben. Ansonsten wird auf die Beschreibung zu Fig. 1 Bezug genommen.In Fig. 2 a spinning device is shown, which is especially for production of FDY yarns is suitable. Since the process flow from spinning to for winding is similar to the spinning process shown in Fig. 1, only the deviations from the procedure and the device of FIG. 1 described. Otherwise, the Description to Fig. 1 referenced.

Nach Verlassen der Spinnzone werden die Fäden 12.1 bis 12.4 derart zusammengefaßt, daß sie mit geringem Abstand zueinander auf die Galette 24 auflaufen können. Hierzu dient ein vor der Galette 24 angeordneter Fadenführer 22. Die Galette 24 wird von den Fäden mehrfach umschlungen, wobei die Fäden zwischen einer Überlaufrolle 23 und der Galette 24 hin- und hergeführt werden. Von einer Streckgalette 27 werden die Fäden von der Galette 24 abgezogen. Die Galette 27 mit der Überlanfrolle 26 wird ebenfalls mehrmals von den Fäden 12 umschlungen. Die Galette 24 wird mittels dem Galettenmotor 25 angetrieben. Die Galette 27 wird mittels dem Galettenmotor 28 angetrieben. Zur Verstreckung der Fäden wird die Galette 27 mit höherer Umfangsgeschwindigkeit betrieben als die Galette 24. Auch hierbei ist die Galette 24 zur Erwärmung der Fäden beheizt. Es ist jedoch auch möglich, das Verfahren mit kalten Galetten zu betreiben. Hierbei erfolgt die Erwärmung zischen der Galette 24 und der Präparationseinrichtung 6 mittels eines Heizrohres oder einer Heizschiene. Es ist jedoch auch möglich, den Faden vor Auflauf auf die Galette 24 durch eine Dampfdüse zu führen.After leaving the spinning zone, the threads 12.1 to 12.4 become like this summarized that they are close to each other on the godet 24 can accumulate. For this purpose, one arranged in front of the godet 24 is used Thread guide 22. The godet 24 is repeated by the threads looped, the threads between an overflow roller 23 and the Galette 24 to be moved back and forth. From a stretch godet 27 the threads are removed from the godet 24. The godet 27 with the Overlap roll 26 is also wrapped several times by the threads 12. The godet 24 is driven by the godet motor 25. The Galette 27 is driven by the godet motor 28. to Drawing of the threads becomes the godet 27 at a higher peripheral speed operated as the godet 24. Also here is the godet 24 heated to heat the threads. However, it is also possible that Operate procedures with cold godets. This is where the heating takes place hiss the godet 24 and the preparation device 6 by means of a heating pipe or a heating rail. However, it is also possible to Thread into the godet 24 through a steam nozzle before emergence to lead.

Nachdem die Fäden die Verstreckzone durchlaufen haben, erfolgt nach dem Fadenführer 29 eine Aufspreizung der Fäden zu den einzelnen Anfwickelstellen der Aufwickeleinrichtung. Zwischen dem Fadenführer 21 und dem Kopffadenführer 14 ist wiederum ein Lieferwerk 13 in dem Fadenlauf angeordnet. Die Lieferwerke 13 ist über einen Stellmotor 34 ansteuerbar. Der Stellmotor 34 ist mit einer Steuereinrichtung 32 gekoppelt. Im Fadenlauf zwischen dem Fadenführer 21 und dem Lieferwerk 13 ist ein Fadenzugkraftsensor 31 angeordnet. Der Fadenzugkraftsensor 31 ist ebenfalls mit der Steuereinrichtung 32 verbunden. Durch diese Verfahrensvariante ist es möglich, die Lieferwerke 13 in Abhängigkeit von der Fadenzugkraft des in die Lieferwerke eintretenden Fadens zu steuern. Zusätzlich kann mit der Steuereinrichtung 32 ein Wert vorgegeben werden, der bei der Aufwickhmg des Fadens unbedingt einzuhalten ist. Durch diese Anordnung ist es möglich, Fadenzugkraftänderungen, die während des laufenden Prozesses in dem Faden auftreten können, z.B. durch Verschleißerscheinungen, direkt auszuregeln. Die Lieferwerke 13 erhält keine vorgegebene Einstellung. Die Fadenzugkraft in dem Faden wird somit in Abhängigkeit von den Prozeßparametern ständig der für die Aufwicklung erforderlichen Fadenzugkraft angepaßt.After the threads have passed through the stretching zone, follows the thread guide 29 a spreading of the threads to the individual Rewind points of the rewinder. Between the thread guide 21 and the head thread guide 14 is in turn a delivery unit 13 in the Thread run arranged. The delivery mechanism 13 is via a servomotor 34 controllable. The servomotor 34 is provided with a control device 32 coupled. In the thread path between the thread guide 21 and the Delivery mechanism 13, a thread tension sensor 31 is arranged. The Thread tension sensor 31 is also connected to the control device 32 connected. This process variant makes it possible to supply the plants 13 depending on the thread tension in the supplying plants to control entering thread. In addition, with the control device 32 a value can be specified when the thread is wound up must be strictly observed. With this arrangement it is possible Thread tension changes that occur during the ongoing process in the Thread can occur, e.g. through wear and tear, directly auszuregeln. The delivery plants 13 do not receive a predefined setting. The Thread tension in the thread is thus dependent on the process parameters constantly the thread tension required for winding customized.

In Fig. 3 ist schematisch ein Lieferwerk 13 dargestellt, die es ermöglicht, eine Fadenzugkraft im Faden abzubauen. Das Lieferwerk weist einen scheibenförmigen Träger 33 auf. An dem Träger 33 sind die Rollen 35 und 36 drehbar gelagert. Die Rolle 35 und die Rolle 36 sind angetrieben. Der scheibenförmige Träger 33 ist über den Verstellmotor 34 in Verstellrichtung 37 drehbar. Der Faden 12 ist um die Rolle 35 und 36 S-förmig geführt. Je nach Einstellung werden die Rollen 35 und 36 mehr oder weniger stark von dem Faden 12 umschlungen. Durch die Veränderung der Umschlingungswinkel an den Rollen 35 wird der Grad des Abbaus der Fadenzugkraft eingestellt. Ein Abbau der Fadenzugkraft erfolgt hierbei über einen Schlupf, der zwischen dem Faden und der Rolle 35 oder 36 eingestellt wird. Hierzu ist die Umfangsgeschwindigkeit der Rolle 35 oder 36 höher als die Auflaufgeschwindigkeit des Fadens. In Fig. 3, a delivery plant 13 is shown schematically, which enables to reduce a thread tension in the thread. The delivery plant has one disc-shaped carrier 33. The rollers 35 are on the carrier 33 and 36 rotatably mounted. The roller 35 and the roller 36 are driven. The disk-shaped carrier 33 is in via the adjusting motor 34 Adjustment direction 37 rotatable. The thread 12 is S-shaped around the roller 35 and 36 guided. Depending on the setting, the rollers 35 and 36 become more or less wrapped in the thread 12. By the change the wrap angle on the rollers 35 becomes the degree of Reduction of the thread tension set. The thread tension is reduced in this case via a slip which is between the thread and the roller 35 or 36 is set. This is the peripheral speed of the roll 35 or 36 higher than the thread speed.

Für den Fall, daß eine Fadenzugkraft aufgebaut werden muß, können die Rollen 35 und 36 durch nicht angetriebene Rollen oder feststehende Stifte ersetzt werden. Somit kann die Reibung zwischen dem Faden 12 und der jeweiligen feststehenden Rolle/Stift durch den Grad der Umschlingung eingestellt werden, was einen Fadenzugkraftaufbau zur Folge hat.In the event that a thread tension must be built up, the Rollers 35 and 36 by non-driven rollers or fixed pins be replaced. Thus, the friction between the thread 12 and the respective fixed role / pin by the degree of wrap can be set, which results in a thread tension build-up.

In Fig. 4 und 5 sind zwei weitere Modifikationen des Lieferwerkes gezeigt, wie sie in einer Spinnvorrichtung in Fig. 1 oder 2 eingesetzt werden könnte. In Fig. 4 ist gezeigt, daß der Fadenzugkraftsensor 31 im Fadenlauf vor der Lieferwerk 13 angeordnet ist und über eine Steuereinrichtung 32 mit dem Lieferwerk 13 gekoppelt. Die Steuereinrichtungen 32.1, 32.2 und 32.4 sind mit einem Steuergerät 39 verbunden. Das Steuergerät 39 ist mit der Steuereinrichtung 32.3 gekoppelt. Die Steuereinrichtung 32.3 ist ebenfalls mit einem Fadenzugkraftsensor 31.3 verbunden, wobei der Fadenzugkraftsensor 31.3 im Fadenlauf hinter dem Lieferwerk 13.3 angeordnet ist. Die Fadenzugkraftmessung an dem Faden 12.3 wird hierbei als Referenzmeßstelle verwendet. Das Meßsignal des Fadenzugkraftsensors 13.3 wird über das Steuereinrichtung 32.3 dem Steuergerät 39 zugeführt. Vom Steuergerät 39 erfolgt eine Weiterleitung des Referenzsignals zu den Steuereinrichtungen 32.1, 32.2 und 32.4.4 and 5 are two further modifications of the delivery plant shown as used in a spinning device in Fig. 1 or 2 could be. In Fig. 4 it is shown that the thread tension sensor 31 in Thread run is arranged in front of the delivery mechanism 13 and via a Control device 32 coupled to the delivery unit 13. The Control devices 32.1, 32.2 and 32.4 have a control device 39 connected. The control device 39 is connected to the control device 32.3 coupled. The control device 32.3 is also with a Thread tension sensor 31.3 connected, wherein the thread tension sensor 31.3 is arranged in the thread path behind the delivery mechanism 13.3. The thread tension measurement on the thread 12.3 is used here as a reference measuring point used. The measurement signal of the thread tension sensor 13.3 is via the Control device 32.3 supplied to control device 39. From control unit 39 the reference signal is forwarded to the control devices 32.1, 32.2 and 32.4.

In der Steuereinrichtung 32.1, 32.2 und 32.4 erfolgt ein Abgleich zwischen dem Referenzsignal und dem Signal aus der Fadenzugkraftmessung im Fadenlauf vor dem jeweiligen Lieferwerk. Die Differenz wird sodann als Stellsignal des jeweiligen Lieferwerks vorgegeben. Somit wird erreicht, daß die Fäden 12.1, 12.2, 12.3 und 12.4 eine gleiche Fadenzugkraft bei Eintreten in die Aufwickelzone aufweisen. A comparison takes place in the control device 32.1, 32.2 and 32.4 between the reference signal and the signal from the thread tension measurement in the thread run in front of the respective delivery plant. The The difference is then used as a control signal from the respective supplier specified. It is thus achieved that the threads 12.1, 12.2, 12.3 and 12.4 an equal thread tension when entering the winding zone exhibit.

In Fig. 5 ist ein weiteres Ausführungsbeispiel gezeigt, das im Vergleich zu der Anordnung von Fig. 2 sich dadurch unterscheidet, daß der Fadenzugkraftsensor 31 nicht im Fadenlauf vor dem Lieferwerk sondern im Fadenlauf nach dem Lieferwerk 13 angeordnet ist. Diese Anordnung ist insbesondere zur Regelung der Fadenzugkraft geeignet. Hierzu wird der Steuereinrichtung 40 jeweils eine Fadenzugkraft durch ein Steuergerät 39 vorgegeben, die mit dem Lieferwerk 13 eingestellt wird. Durch die Messung der Fadenzugkraft nach das Lieferwerk durch den Fadenzugkraftsensor 31 wird der Steuereinrichtung 40 das Meßsignal zugeführt und mit dem vorgegebenen Wert verglichen. Die Abweichungen zwischen dem Vorgabewert und dem Meßwert werden als Regelgröße dem Lieferwerk 13 zugeführt. Diese Anordnung besitzt zudem den Vorteil, daß Fadenzugkraftschwankungen, die aus der Aufwicklung resultieren durch das Lieferwerk 13 ausgeglichen werden können.5 shows a further embodiment, which is compared 2 differs in that the Thread tension sensor 31 not in the thread run in front of the delivery plant but is arranged in the thread path after the feed mechanism 13. This arrangement is particularly suitable for regulating the thread tension. For this, the Control device 40 each have a thread tension by a control device 39 predetermined, which is set with the delivery plant 13. Through the Measurement of the thread tension according to the delivery plant by the thread tension sensor 31 the control signal 40 is supplied with the measurement signal compared to the specified value. The deviations between that The default value and the measured value are sent to the supplying plant 13 as a controlled variable fed. This arrangement also has the advantage that Thread tension fluctuations that result from the winding by the Supply plant 13 can be compensated.

Das erfindungsgemäße Verfahren ist zur Veränderung der Fadenzugkraft der Fäden in einer mehrstelligen Spinnanlage sowohl zur Herstellung von FDY-, POY-, BCF-, Technisch Garn und HOY-Garnen geeignet. Ebenso sind alle Arten von Fadenmaterialien wie Polypropylen, Polyester, Polyamid und Viskose mit dem Verfahren zu bearbeiten.The method according to the invention is for changing the thread tension of the threads in a multi-digit spinning plant for the production of FDY, POY, BCF, technical yarn and HOY yarns are suitable. As well are all types of thread materials such as polypropylene, polyester, Machining polyamide and viscose using the process.

Da jede Wickelstelle 41 den gleichen Aufbau besitzt, werden nachfolgend die Vorrichtungsteile anhand einer Wickelstelle erläutert. Die Förderrolle 42 ist mit einer Antriebswelle 47 verbunden, die mittels eines Motors 49 angetrieben wird. Die Förderrolle 43 ist an der Antriebswelle 48 befestigt, die mittels des Motors 50 angetrieben wird. Die Förderrollen 42 und 43 werden vom Faden 12 Z-förmig umschlungen.6 and 7 is a winding device with integrated Supplying plants shown. In this respect, the following description applies to Fig. 6 and Fig. 7 alike. The winding device consists of a Machine frame 20. There are a total of four on the machine frame 20 Winding points 41.1, 41.2, 41.3 and 41.4 arranged. Each of the Winding points 41.1 to 41.4 initially point in the thread running direction Delivery plant 13 on. The delivery plants 13.1 to 13.4 are on a carrier 44 arranged. The carrier 44 is fixed to the machine frame 20 connected. Each of the delivery plants 13.1 to 13.4 have two below one another arranged conveyor rollers 42 and 43. Since each winding point 41 den has the same structure, the device parts are based on a winding point explained. The conveyor roller 42 is with a drive shaft 47 connected, which is driven by a motor 49. The supporting role 43 is attached to the drive shaft 48, which by means of the motor 50 is driven. The conveyor rollers 42 and 43 are Z-shaped by the thread 12 entwined.

Unterhalb der Lieferwerke 13 ist ein Kopffadenführer 14 und danach eine Changiereinrichtung 15 angeordnet. Zwischen dem Kopffadenführer 14 und der Changiereinrichtung 15 wird das sogenannte Changierdreieck 45 gebildet. Die Changiereinrichtung 15 ist hierbei als Flügelchangierung ausgeführt. Dabei wird der Faden durch zwei oder mehrere gegensinnig angetriebene Flügel innerhalb eines Changierhubes hin- und hergeführt. An den Changierhubenden erfolgt jeweils die Übergabe zwischen zwei in einem Übergabepunkt aufeinandertreffende Flügeln. Unterhalb der Changiereinrichtung 15 ist eine Andrückwalze 16 in einer Schwinge 46 mit einer Achse 51 gelagert. Die Andrückwalze 16 liegt mit einer vorgegebenen Kraft auf der Spulenoberfläche der Spule 18 auf. Die Spule 18 wird auf einer Hülse 52 gewickelt. Die Hülse 52 ist auf einer Spulspindel 17 aufgesteckt. Die Spulspindel 17 ist drehbar auskragend im Maschinengestell 20 gelagert.Below the feed mechanisms 13 is a head thread guide 14 and then one Traversing device 15 arranged. Between the head thread guide 14 and the traversing device 15 becomes the so-called traversing triangle 45 educated. The traversing device 15 is in this case as wing traversing executed. The thread becomes counter-rotating by two or more driven wings back and forth within a traversing stroke. On the transfer ends are transferred between two in wings meeting at a transfer point.

Der einlaufende Faden 12 in der Wickelstelle 41.1 läuft zunächst in das Lieferwerk 13.1 ein. Die Förderrollen 42 und 43 des Lieferwerks 13.1 sind mit einer Umfangsgeschwindigkeit angetrieben, die größer ist als die Fadengeschwindigkeit. Somit wird ein bestimmter Abbau der Fadenzugkraft im Faden erreicht. Der Spannungsabbau wird hierbei im wesentlichen über die eingestellte Umfangsgeschwindigkeit bestimmt. Die Umschlingungswinkel an den Förderrollen sind in diesem Ausführungsbeispiel fest vorgegeben. Anschließend läuft der Faden in das Changierdreieck hinein und wird mittels der Changiereinrichtung 15 und der Andrückwalze 16 auf der Spule 18 abgelegt. Die Umfangsgeschwindigkeit der Spule 18 ist hierbei konstant. Die Regelung der Umfangsgeschwindigkeit de Spule erfolgt über einen Spindelmotor, der in Abhängigkeit von der Drehzahl der Andrückwalze gesteuert wird.The incoming thread 12 in the winding station 41.1 initially runs into the Delivery plant 13.1. The conveyor rollers 42 and 43 of the delivery plant 13.1 are driven at a peripheral speed that is greater than that Yarn speed. Thus, a certain reduction in the thread tension reached in the thread. The voltage reduction is essentially about determines the set peripheral speed. The Wrap angles on the conveyor rollers are in this Embodiment predefined. Then the thread runs into it Traverse triangle and is by means of the traversing device 15 and the pressure roller 16 placed on the spool 18. The The peripheral speed of the coil 18 is constant. The regulation the peripheral speed of the coil is carried out by a spindle motor is controlled depending on the speed of the pressure roller.

Um einen kontinuierlichen Spulvorgang zu ermöglichen, kann die Spulspindel 17 in einem Spulrevolver (hier nicht gezeigt) gelagert sein. Der Spulrevolver ist dabei drehbar im Maschinengestell angeordnet. An dem Spulrevolver ist um 180° versetzt zu der ersten Spulspindel eine weitere Spulspindel angeordnet. Sobald die Spulen 18 auf der Spulspindel 17 fertig gewickelt sind, wird der Spulrevolver verschwenkt, so daß die zweit Spulspindel mit Leerhülsen in die entsprechende Arbeitsposition geschwenkt wird.To enable a continuous winding process, the Be winding spindle 17 in a winding turret (not shown here).

Die in Fig. 6 und 7 gezeigte Aufwickeleinrichtung könnte in der Spinnvorrichtung aus Fig. 1 oder 2 eingesetzt werden. Es ist jedoch auch möglich, eine derartige Aufwickeleinrichtung in eine Spinnanlage einzusetzen, bei welcher die Fäden im parallelen Lauf zwischen der Spinndüse und den Wickelstellen angeordnet sind.6 and 7 could be in the Spinning device of Fig. 1 or 2 are used. However, it is also possible, such a winding device in a spinning system to use, in which the threads in the parallel run between the Spinneret and the winding stations are arranged.

In Fig. 8 ist ein weiteres Ausführungsbeispiel eines Lieferwerks gezeigt, wie sie in der Spinnvorrichtung aus Fig. 1 und Fig. 2 oder in einer Aufwickeleinrichtung nach Fig. 6 eingesetzt werden könnte. Das Lieferwerk besteht hierbei aus drei Förderrollen 42, 43 und 53. Die Förderrollen 42 und 43 sind mit Abstand zueinander parallel zum Fadenlauf des Fadens 12 angeordnet. Die Förderrolle 42 wird hierbei über die Antriebswelle 47 und die Förderrolle 43 über die Antriebswelle 48 angetrieben. Die Förderrole 53 ist mit einer Antriebswelle 54 verbunden, die in einer Gabel 55 gelagert ist. Die Gabel 55 ist an einer Verstelleinrichtung 56 angeordnet, so daß die Gabel 55 im wesentlichen quer zur Fadenlaufrichtung verschiebbar ist. Die Förderrolle 53 ist zu den Förderrollen 42 und 43 auf der gegenüberliegenden Seite des Fadenlaufs angeordnet. In der gezeigten Stellung ist die Verstelleinrichtung 56 mit der Förderrolle 53 im eingefahrenen Zustand, also aus dem Fadenlauf ausgeschwenkt, gezeigt. Hierbei kann der Faden 12 ohne Umschlingung ungehindert das Lieferwerk passieren. Die Förderrolle 53 ist nun in der Mitte zwischen den Förderrollen 42 und 43 plaziert. Da der Abstand zwischen den Förderrollen 42 und 43 größer ist als der Durchmesser der Förderrolle 53, kann die Förderrolle 53 mittels der Verstelleinrichtung 56 in den Zwischenraum der Förderrollen 42 und 43 eingeschwenkt werden. Dabei durchdringt die Förderrolle 53 die Fadenlaufebene, so daß der Faden 12 durch die Förderrolle 53 zwangsgeführt wird und jede der Förderrollen 42, 43 und 53 teilumschlingt. Diese Stellung ist in der Fig. 8 gestrichelt dargestellt. Der Verstellweg in der Förderrolle 53 ist variabel, so daß unterschiedliche Umschlingungswinkel einstellbar sind.8 shows a further exemplary embodiment of a delivery plant, as in the spinning device from FIG. 1 and FIG. 2 or in a 6 could be used. The The delivery plant consists of three conveyor rollers 42, 43 and 53. The Conveyor rollers 42 and 43 are parallel to each other at a distance Thread run of the thread 12 arranged. The conveyor roller 42 is over the drive shaft 47 and the conveyor roller 43 via the drive shaft 48 driven. The conveyor roller 53 is connected to a drive shaft 54, which is mounted in a fork 55. The fork 55 is on an adjusting device 56 arranged so that the fork 55 is substantially transverse to Thread running direction is displaceable. The conveyor roller 53 is one of the Conveyor rollers 42 and 43 on the opposite side of the thread path arranged. In the position shown, the adjusting device 56 is included the conveyor roller 53 in the retracted state, that is, from the thread path swung out, shown. Here, the thread 12 can be looped pass the delivery plant unhindered. The conveyor roller 53 is now in the Placed midway between conveyor rollers 42 and 43. Because the distance between the conveyor rollers 42 and 43 is larger than the diameter of the Conveyor roller 53, the conveyor roller 53 can by means of the adjusting device 56 in the Space between the conveyor rollers 42 and 43 are pivoted. there passes through the conveyor roller 53, the thread running plane, so that the thread 12th is positively guided by the conveyor roller 53 and each of the conveyor rollers 42, 43 and 53 partially wrapped. This position is dashed in Fig. 8 shown. The adjustment path in the conveyor roller 53 is variable, so that different wrap angles are adjustable.

Die Förderrollen 42, 43 und 53 sind an einem Träger 61 angebracht. Seitlich an dem Träger 61 ist eine Fadenaushebevorrichtung befestigt, die einen Schwenkarm 59 und einen Fadenführer 58 aufweist. Der Schwenkarm 59 ist an der Achse 60 gelagert. Der Fadenführer 58 durchdringt mit seinem freien Ende die Fadenlaufebene. Somit wird beim Verschwenken des Schwenkarms in Richtung aus der Zeichnungsebene heraus der Faden 12 vom Fadenführer 58 erfaßt.The conveyor rollers 42, 43 and 53 are attached to a carrier 61. A thread lifting device is attached laterally to the carrier 61 has a swivel arm 59 and a thread guide 58. The Swivel arm 59 is mounted on the axis 60.

Auf der dem Träger 61 gegenüberliegenden Stirnseite weisen die Förderrollen 42, 43 und 53 jeweils eine Anlegeschräge 57 auf. Damit wird das Anlegen eines Fadens unterstützt. An dem Träger 61 ist ebenfalls der Schwenkarm 59 an der Achse 60 schwenkbar gelagert. An dem freien Ende des Schwenkarms 59 ist der Fadenführer 58 befestigt. Der Fadenführer 58 durchdringt dabei die Fadenlaufebene. In der Betriebsstellung ist der Schwenkarm parallel zur Fadenlaufrichtung ausgerichtet. In dieser Situation wird der Faden 12 über den Fadenführer 21 durch das Lieferwerk zu dem Fadenführer 14 geführt. Wird nun der Schwenkarm 59 in Richtung des Fadens 12 verschwenkt, so durchdringt er die Fadenlaufebene, so daß der Faden nach 90°-Verschwenkung durch den Fadenführer 58 aus dem Lieferwerk ausgehoben wird. Beim Anlegen des Fadens in das Lieferwerk wird der Schwenkarm in seine Ausgangsposition zurückverschwenkt. Der Faden 12 gleitet sodann selbsttätig in den Bereich der Förderrollen 42 und 43 ein.FIG. 9 is a schematic side view of the delivery plant from FIG. 8 shown. Here, the conveyor rollers 42, 43 and 53 are on a carrier 61 arranged. On the end face opposite the carrier 61 the conveyor rollers 42, 43 and 53 each have a contact slope 57. This supports the threading. On the carrier 61 also the swivel arm 59 is pivotally mounted on the axis 60. On the free end of the swivel arm 59, the thread guide 58 is attached. The thread guide 58 penetrates the thread running plane. In the operating position the swivel arm is aligned parallel to the thread running direction.

Now the swivel arm 59 pivoted in the direction of the thread 12, it penetrates the Thread running level, so that the thread after 90 ° pivoting through the Thread guide 58 is lifted out of the delivery plant. When creating the Thread into the delivery plant, the swivel arm is in its starting position swiveled back. The thread 12 then slides automatically into the area the conveyor rollers 42 and 43.

In Fig. 10 ist schematisch eine weitere Anordnung von Lieferwerken, wie sie in der Spinnvorrichtung aus Fig. 1 oder 2 eingesetzt werden könnte, gezeigt. Es sind insgesamt sechs Lieferwerke 13.1 bis 13.6 nebeneinander angeordnet. Hierbei wird jedes der Lieferwerke wiederum durch zwei Förderrollen, wie zuvor in Fig. 6 beschrieben, gebildet. Die Förderrollen 42 und 43 sind jeweils auf einer Welle 63 und 64 befestigt. Hierbei sind die Eingangsförderrollen 42.1 und 42.2 benachbarter Lieferwerke 13.1 und 13.2 über einen Riemen 66 miteinander verbunden. Eine der Wellen 64.1 der Förderrollen 42 wird sodann über einen Riementrieb 71 angetrieben. Der Riementrieb 71 ist hierbei mit einer durch einen Motor angetriebenen Antriebswelle 68 und dem Riemen 67 ausgeführt. Der Riemen 67 umschlingt die Welle 64.1 und die Antriebswelle 68. Bei der in Fig. 10 gezeigten Anordnung werden jeweils zwei Förderrollen gemeinsam über einen Antriebe angetrieben. Es ist jedoch auch möglich, mehrere Förderrollen mit nur einem Antrieb anzutreiben. Eine derartige Kopplung der Antriebe der Förderrollen ist jedoch nur dann sinnvoll, wenn die Fadenzugkräfte in den Fäden vor Einlauf in die Lieferwerke im wesentlichen auf einem gleichen Niveau liegen.In Fig. 10 is a further arrangement of supply plants, such as it could be used in the spinning device of FIG. 1 or 2, shown. There are a total of six supply plants 13.1 to 13.6 side by side arranged. Here, each of the supply plants is in turn by two Conveyor rollers, as previously described in Fig. 6, formed. The conveyor rollers 42 and 43 are each mounted on a shaft 63 and 64. Here are the input conveyor rollers 42.1 and 42.2 of adjacent supply plants 13.1 and 13.2 connected to each other via a belt 66. One of the Waves 64.1 of the conveyor rollers 42 is then a Belt drive 71 driven. The belt drive 71 is here with a drive shaft 68 and belt 67 driven by a motor executed. The belt 67 wraps around the shaft 64.1 and Drive shaft 68. In the arrangement shown in Fig. 10 are each two conveyor rollers driven together by one drive. It is however, it is also possible to use several conveyor rollers with just one drive drive. Such coupling of the drives of the conveyor rollers is However, this only makes sense if the thread tensile forces are present in the threads Entry into the supply plants are essentially at the same level.

Der Antrieb der Ausgangsförderrollen 43.1 und 43.2 erfolgt analog mittels dem Gruppenantrieb 62 über die Antriebswelle 65 und den Riemen 70 und 69.The output conveyor rollers 43.1 and 43.2 are driven analogously by means of the group drive 62 via the drive shaft 65 and the belt 70 and 69th

Die Lieferwerke 13.3 und 13.4 sowie die Lieferwerke 13.5 und 13.6 sind ebenfalls - wie zuvor anhand der Lieferwerke 13.1 und 13.2 beschrieben - angetrieben. The supplying plants 13.3 and 13.4 as well as the supplying plants 13.5 and 13.6 are likewise - as before using the supplying plants 13.1 and 13.2 described - driven.
