Nachdem die Spule fertiggewickelt ist, erfolgt ein Spulenwechsel. Hierzu ist es erforderlich, daß der Faden zunächst durchtrennt wird, so daß die volle Spule mit losem Fadenende gegen eine neue Leerhülse gewechselt werden kann. Das Fadenende des kontinuierlich zulaufenden Fadens wird während des Wechsels mittels einer pneumatischen Absaugeinrichtung aufgenommen und abgeführt. Nachdem der Spulenwechsel erfolgt ist, wird der Faden mittels einer Fangeinrichtung gefangen und auf der neuen Hülse angewickelt.The device and the method are known from EP 0 311 827.

Hierbei ist nur eine Auslenkung in der Übergabeebene erforderlich. Der Greifarm der Übergabeeinrichtung erfaßt den Faden dabei im Fadenlauf zwischen der bereits abgehobenen Spule und dem Fadenführer. Diese Ausbildung besitzt desweiteren den Vorteil, daß beim Abheben der Spule von der Treibwalze der Faden durch die Übergabeeinrichtung sicher in dem Fadenführer geführt bleibt. Die Übergabeebene ist hierbei vorzugsweise als Normalebene der Spule ausgebildet und enthält den Abbindewickel der Spule.In a particularly advantageous development of the device according to Claim 2 are the thread guide and the suction device in one Transfer plane arranged so that the loose thread end on the full spool can be safely placed on the binding reel. Furthermore, by simple pivoting movement of the thread transfer device into the Cutting device of the suction device are introduced. Here is only a deflection in the transfer level is required. The gripper arm of the Transfer device detects the thread in the thread path between the already lifted bobbin and the thread guide. This training has further the advantage that when lifting the spool from the drive roller the thread is safely guided in the thread guide by the transfer device remains. The transfer level is preferably the normal level Coil formed and contains the binding coil of the coil.

Die Ausführung der Vorrichtung gemäß Anspruch 3 gewährleistet, daß der Faden vor Eintritt in die Schneideinrichtung bereits von dem pneumatischen Absauganschluß erfaßt wird. Das Fadenende des zulaufenden Fadens wird somit sicher nach dem Durchtrennen in der Schneideinrichtung aufgenommen und abgeführt. Die Schneideinrichtung weist hierzu vorzugsweise eine Messerklinge auf, die mit dem Greifarm der Übergabeeinrichtung derart zusammenwirkt, daß der Faden sauber und schnell durch die Messerklinge geschnitten wird.The execution of the device according to claim 3 ensures that the Thread from the pneumatic already before entering the cutting device Suction port is detected. The thread end of the incoming thread is thus safely recorded in the cutting device after severing and dissipated. For this purpose, the cutting device preferably has one Knife blade on the gripper arm of the transfer device such interacts that the thread cleanly and quickly through the knife blade is cut.

Um den laufenden Faden sicher in die Saugöffnung des Absauganschlusses zu führen, ist dieser gemäß Anspruch 4 vorteilhaft geschlitzt ausgeführt. Die besonders vorteilhafte Weiterbildung der Vorrichtung gemäß Anspruch 5 ermöglicht, daß der Faden ohne weitere Hilfsmittel allein durch Bewegung des Fadenführers in der Fangeinrichtung gefangen wird. Hierzu wird der Faden nur in Längsrichtung parallel zur Hülse ausgelenkt. Durch eine zusätzliche gleichgerichtete Bewegung der Absaugeinrichtung läßt sich zudem die Auslenkung des Fadens minimieren.To securely feed the running thread into the suction opening of the suction connection lead, this is advantageously designed slotted according to claim 4. The particularly advantageous development of the device according to claim 5 allows the thread to move without further aids simply by movement the thread guide is caught in the catching device. For this, the Thread deflected parallel to the tube only in the longitudinal direction. By a additional rectified movement of the suction device can also minimize the deflection of the thread.

Bei der erfindungsgemäßen Aufwickelvorrichtung, bei welcher die Hülse zwischen zwei an einem Spulenhalter angeordneten Spannteller gespannt ist und die Fangeinrichtung an einem der Spannteller ausgebildet ist, läßt sich der Faden auf einfache Weise fangen. Hierzu wird der Faden im schrägen Lauf über die Stirnkante des Spanntellers geführt, so daß der Faden in einen in der Stirnkante des Spanntellers eingebrachten Fangschlitz selbsttätig einfällt. In the winding device according to the invention, in which the sleeve is stretched between two clamping plates arranged on a coil holder and the catching device is formed on one of the clamping plates, can catch the thread in a simple way. To do this, thread the thread at an angle Run over the front edge of the tension plate, so that the thread in one in the front edge of the clamping plate inserted slot falls automatically.

Zudem ist die Anordnung des Fadenführers und der Fangeinrichtung derart vorteilhaft, daß der Faden und der Spannteller eine gleichgerichtete Bewegung ausführen. Damit tritt keine Verschlappung und damit keine überhöhte Fadenspannungsschwankung ein.In addition, the arrangement of the thread guide and the catching device is such advantageous that the thread and the tension plate have a rectified movement To run. So there is no waste and therefore no excessive Thread tension fluctuation.

Bei den zuvor beschriebenen Vorgängen zum Spulenwechsel, zum Fangen und zum Anwickeln des Fadens ist vorausgesetzt, daß der Faden zu Beginn des Spulenwechsels mittels einer Hilfseinrichtung auf einem Changierfadenführer geführt und anschließend von dem Fadenführer übernommen wird. Der Fadenführer ist hierbei vorzugsweise mit einem Antrieb ausgeführt, der den Fadenführer in Längsrichtung parallel zur Hülse bewegt und die Bewegung des Fadenführers richtungsunabhängig mit veränderlicher Geschwindigkeit ausführt. In diesem Fall könnte der Antrieb beispielsweise als Linearantrieb ausgeführt sein.In the previously described processes for changing bobbins, catching and for winding the thread is provided that the thread at the beginning of the Bobbin change by means of an auxiliary device on a traversing thread guide guided and then taken over by the thread guide. The Thread guide is preferably carried out with a drive that the Thread guide moved in the longitudinal direction parallel to the tube and the movement of the thread guide regardless of direction with variable speed performs. In this case, the drive could be a linear drive, for example be executed.

Bei einer besonders vorteilhaften Weiterbildung der Erfindung ist der Fadenführer als ein Changierfadenführer einer Changiereinrichtung ausgeführt. Hierzu kann der Changierfadenführer den Faden außerhalb und innerhalb des Spulbereichs in Längsrichtung parallel zur Hülse führen. Diese Ausführung besitzt den Vorteil, daß keine zusätzliche Steuereinheit zur Steuerung der Changiereinrichtung erforderlich ist. Alle Vorgänge während des Aufspulens, während des Spulenwechsels und während des Fangens werden über eine Steuereinrichtung der Changiereinrichtung gesteuert.In a particularly advantageous development of the invention Thread guide designed as a traversing thread guide of a traversing device. For this purpose, the traversing thread guide can take the thread outside and inside the Guide the winding area in the longitudinal direction parallel to the core. This execution has the advantage that no additional control unit for controlling the Traversing device is required. All operations during winding, during the bobbin change and while catching are over a Control device of the traversing device controlled.

Nachdem der Faden gefangen wurde und auf der Hülse angewickelt ist, erfolgt die eigentliche Spulreise, d.h. das Aufwickeln der Spule. Nachdem die Spule fertiggestellt ist, wird zur Einleitung des Spulenwechsels der Faden von der Absaugeinrichtung übernommen. Hierzu bleibt der den Faden führende Changierfadenführer in einer Übergabeebene stehen. Die Übergabeeinrichtung führt sodann den Faden in die Absaugeinrichtung. Nachdem nun der Spulenwechsel erfolgt ist und die Leerhülse in dem Spulenhalter zwischen den Spanntellern gespannt ist, beginnt das Anlegen des Fadens. Zunächst wird die Hülse auf eine für das Anlegen erforderliche Drehzahl beschleunigt. Sobald die Drehzahl erreicht ist, wird der Antrieb des Changierfadenführers aktiviert, und der Changierfadenführer führt den Faden in eine Fangposition, in welcher der Faden schräg über eine Fangebene der Fangeinrichtung läuft, beispielsweise eine Stirnkante des Spanntellers. Die Ausbildung der erfindungsgemäßen Vorrichtung gemäß Anspruch 9 ist besonders vorteilhaft, um den Faden ohne Zeitverzögerung direkt nach Erreichen der für das Aufwickeln erforderlichen Spuldrehzahl mittels der Fangeinrichtung zu fangen und auf der Hülse aufzuwickeln. Hierzu wird die Drehzahl der Hülse laufend erfaßt. Sobald eine vorgegebene Spuldrehzahl erreicht ist, wird der Antrieb des Fadenführers aktiviert. Der Fadenführer führt dann die zum Fangen des Fadens und zum Anwickeln des Fadens auf der Hülse entsprechende Bewegungen aus. Die Spuldrehzahl entspricht der Drehzahl der Hülse, die eine Umfangsgeschwindigkeit an der Hülse erzeugt, die im wesentlichen gleich der Fadengeschwindigkeit ist.After the thread has been caught and wound on the core, the actual winding travel takes place, i.e. winding the spool. After this the bobbin is finished, the thread is used to initiate the bobbin change taken over by the suction device. This remains the thread leading traversing thread guides are on a transfer level. The The transfer device then leads the thread into the suction device. Now that the bobbin has been changed and the empty tube in it The bobbin holder is stretched between the clamping plates, starts to put on the Thread. First, the sleeve is placed on one necessary for the application Speed accelerated. As soon as the speed is reached, the drive of the The traversing thread guide is activated, and the traversing thread guide guides the thread in a catching position in which the thread is inclined over a catching plane of the Catcher runs, for example an end edge of the clamping plate. The Formation of the device according to the invention according to claim 9 particularly advantageous to directly after the thread without time delay Reaching the winding speed required for winding up using the Catch the catching device and wind it up on the core. For this, the Speed of the sleeve continuously recorded. As soon as a predetermined winding speed the drive of the thread guide is activated. The thread guide then lists the for catching the thread and for winding the thread movements corresponding to the sleeve. The spool speed corresponds to Speed of rotation of the sleeve, which produces a peripheral speed on the sleeve, which is essentially equal to the thread speed.

Diese Ausbildung bietet jedoch auch die Möglichkeit, daß der Bewegungsablauf des Fadenführers auch in die Beschleunigungsphase oder Verzögerungsphase der Hülse gelegt wird. Dies ist insbesondere vorteilhaft in den Fällen, bei denen der Faden in der Fangeinrichtung zunächst auf einem größeren Durchmesser als der Hülsendurchmesser gefangen wird. Daher muß zur Einhaltung einer im wesentlichen konstanten Aufspulgeschwindigkeit des Fadens die mit Drehzahl der Hülse rotierende Fangeinrichtung mit einer geringeren Drehzahl als der Spuldrehzahl während des Fangens angetrieben sein.However, this training also offers the possibility that the Sequence of movements of the thread guide also in the acceleration phase or Delay phase of the sleeve is placed. This is particularly advantageous in the cases in which the thread in the catching device is initially on a larger diameter than the sleeve diameter is caught. Therefore to maintain a substantially constant winding speed of the Fadens the catching device rotating with the speed of the sleeve with a driven at a lower speed than the spool speed during catching his.

Eine besonders vorteilhafte Ausführung der erfindungsgemäßen Vorrichtung gemäß Anspruch 10 besitzt den Vorteil, daß der Faden ohne wesentliche Verzögerung sofort bei Erreichen einer Fangposition des Fadenführers von der Fangeinrichtung gefangen wird. Da der Faden bis zum Fangen weiterhin in der Absaugeinrichtung geführt ist, führt diese Variante zu einer Reduzierung der Abfallmenge des Fadens.A particularly advantageous embodiment of the device according to the invention according to claim 10 has the advantage that the thread without essential Delay immediately when the thread guide reaches a catch position of the catching device is caught. Because the thread continues until caught is guided in the suction device, this variant leads to a Reduction of the amount of waste of the thread.

Weitere vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen definiert.Further advantageous developments of the invention are in the Subclaims defined.

Die erfindungsgemäße Vorrichtung sowie das Verfahren sind anhand einiger Ausführungsbeispiele im folgenden unter Hinweis auf die beigefügten Zeichnungen näher beschrieben.The device according to the invention and the method are based on some Embodiments below with reference to the accompanying Drawings described in more detail.

In Fig. 1 und Fig. 2 ist ein erstes Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung innerhalb einer Aufwickelvorrichtung gezeigt, wie sie beispielsweise in einer Texturiermaschine eingesetzt sein kann. Die nachfolgende Beschreibung gilt daher für Fig. 1 und Fig. 2, insoweit nichts anderes gesagt ist.In Fig. 1 and Fig. 2 is a first embodiment device according to the invention shown within a winding device, as it can be used for example in a texturing machine. The The following description therefore applies to FIGS. 1 and 2, insofar as nothing other is said.

Die Aufwickelvorrichtung weist einen schwenkbaren Spulenhalter 26 auf, der an einer Schwenkachse 40 gelagert ist. Die Schwenkachse 40 ist an einem Maschinengestell 41 befestigt. An den freien Enden des gabelförmigen Spulenhalters 26 sind zwei sich gegenüberliegende Spannteller 27 und 28 drehbar gelagert. Zwischen den Spanntellern 27 und 28 ist eine Hülse 13 zur Aufnahme einer Spule gespannt. Hierzu weisen die Spannteller 27 und 28 jeweils einen konischen Zentrieransatz auf, der teilweise in das Hülsenende hineinragt. Damit ist die Hülse 13 zwischen den Spanntellern 27 und 28 zentriert. An der Oberfläche der Hülse 13 liegt eine Treibwalze 29 an. Die Treibwalze 29 ist auf einer Antriebswelle 31 befestigt. Die Antriebswelle 31 ist an einem Ende mit dem Walzenmotor 30 gekoppelt. Der Walzenmotor 30 treibt die Treibwalze 29 mit im wesentlichen konstanter Geschwindigkeit an. Über Friktion wird nun die Hülse 13 mittels der Treibwalze 29 zu einer Spuldrehzahl angetrieben, so daß der Faden 1 auf der Hülse 13 zu einer Spule aufgewickelt wird. Hierzu ist vor der Treibwalze 29 im Fadenlauf ein Changierfadenführer 6 angeordnet. Der Changierfadenführer ist mit einem Changierantrieb gekoppelt, welcher den Changierfadenführer 6 innerhalb des Spulbereiches oszillierend antreibt. Der Changierantrieb kann beispielsweise durch eine Kehrgewindewelle oder einen Riementrieb gebildet sein.The winding device has a pivotable bobbin holder 26 which is mounted on a pivot axis 40. The pivot axis 40 is at one Machine frame 41 attached. At the free ends of the fork-shaped Coil holder 26 are two opposing clamping plates 27 and 28 rotatably mounted. Between the clamping plates 27 and 28 is a sleeve 13 for Picking up a coil tensioned. For this purpose, the clamping plates 27 and 28 each have a conical centering shoulder, which is partially in the sleeve end protrudes. The sleeve 13 is thus between the clamping plates 27 and 28 centered. A drive roller 29 bears against the surface of the sleeve 13. The Driving roller 29 is fastened on a drive shaft 31. The drive shaft 31 is coupled to the roller motor 30 at one end. The roller motor 30 drives the drive roller 29 at a substantially constant speed. Via friction, the sleeve 13 now becomes a by means of the drive roller 29 Spindle speed driven so that the thread 1 on the sleeve 13 to a Coil is wound. For this purpose, is in front of the drive roller 29 in the thread path Traversing thread guide 6 arranged. The traversing thread guide is with one Coupling drive coupled, which the traversing thread guide 6 within the Drives the winding area oscillating. The traversing drive can, for example be formed by a reverse thread shaft or a belt drive.

Zwischen dem Changierfadenführer 6 und der Hülse 13 ist ein beweglicher Fadenführer 18 angeordnet. Der Fadenführer 18 ist mit einem Antrieb 19 gekoppelt, welcher den Fadenführer 18 in einer parallelen Ebene zur Hülse 13 derart hin- und herbewegt, daß der Fadenführer 18 sowohl innerhalb des Spulbereiches als auch außerhalb des Spulbereiches positionierbar ist. Der Antrieb 19 ist mit einer Steuereinrichtung 8 verbunden. Die Steuereinrichtung 8 kann als Option in Verbindung mit einem an dem Spulenhalter 26 angeordneten Sensor 32 verbunden sein. Der Sensor 32 ist im Bereich des Spanntellers 27 angeordnet und sensiert die Lage einer Fangnut 21 einer Fangeinrichtung 14. Die Fangeinrichtung 14 ist am Spannteller 27 ausgebildet. Der Sensor 32 kann beispielsweise als Impulsgeber ausgeführt sein, der pro Umdrehung ein Signal in Abhängigkeit von der Fangnut 21 abgibt. Diese Impulse werden in der Steuereinrichtung 8 zur Auswertung zur Lage der Fangnut und der Drehzahl der Hülse 13 umgewandelt. Die Hülse 13 ist derart zwischen die Spannteller 27 und 28 eingespannt, daß die Spannteller 27 und 28 ohne Schlupf mit der Drehzahl der Hülse 13 umlaufen.Between the traversing thread guide 6 and the sleeve 13 is a movable Thread guide 18 arranged. The thread guide 18 is with a drive 19 coupled, which the thread guide 18 in a parallel plane to the sleeve 13 so back and forth that the thread guide 18 both within the Spooling area is positioned as well as outside of the winding area. The Drive 19 is connected to a control device 8. The control device 8 can be used as an option in conjunction with one on the coil holder 26 arranged sensor 32 may be connected. The sensor 32 is in the range of Clamping plates 27 arranged and senses the position of a catch groove 21 Catching device 14. The catching device 14 is on the clamping plate 27 educated. The sensor 32 can be designed as a pulse generator, for example be a signal per revolution depending on the catch groove 21st emits. These pulses are used in the control device 8 for evaluation Location of the catch groove and the speed of the sleeve 13 converted. The sleeve 13 is clamped in such a way between the clamping plates 27 and 28 that the Clamping plate 27 and 28 without slipping at the speed of the sleeve 13 circulate.

Auf der zur Changierung gegenüberliegenden Seite zur Hülse 13 ist eine Absaugeinrichtung 37 angeordnet. Die Absaugeinrichtung 37 besteht hierbei aus einer Schneideeinrichtung 38 und einem Absauganschluß 39. Der Absauganschluß 39 ist hierbei zwischen der Schneideinrichtung 38 und der Hülse 13 angeordnet. Der Absauganschluß 39 besitzt eine schlitzförmige Saugöffnung 46, die fluchtend zu einem Messer 47 der Schneideinrichtung 38 angeordnet ist.On the opposite side to the sleeve 13 for traversing is one Suction device 37 arranged. The suction device 37 is here from a cutting device 38 and a suction port 39. The Suction port 39 is here between the cutting device 38 and the Sleeve 13 arranged. The suction port 39 has a slot-shaped Suction opening 46, which is aligned with a knife 47 of the cutting device 38 is arranged.

Bei der in Fig. 1 gezeigten Situation steht in der Aufwickelvorrichtung ein Spulenwechsel unmittelbar bevor. Um den Spulenwechsel einzuleiten, wird der Fadenführer 18 über den Antrieb 19 in dem Spulenbereich in eine Übergabeebene positioniert. Gleichzeitig wird über eine, hier nicht näher erläuterte Hilfseinrichtung der Faden 1 aus dem Changierfadenführer 1 geführt und in den Fadenführer 18 eingelegt. Die Hilfseinrichtung kann hierbei auf einfache Weise als Rampe ausgeführt sein, die parallel zur Bewegung des Changierfadenführers 6 in den Spulbereich eingeführt wird. Damit könnte der Faden 1 selbsttätig aus dem Changierfadenführer 6 geführt werden. Die Rampe wäre vorteilhaft mit dem Fadenführer 18 gekoppelt, so daß der auf die Rampe gleitende Faden selbsttätig in die Führungsnut des Fadenführers 18 einfällt.In the situation shown in Fig. 1 is in the take-up device Reel change immediately before. To initiate the bobbin change, the Thread guide 18 via the drive 19 in the bobbin area in one Transfer level positioned. At the same time is about one, not closer here auxiliary device of the thread 1 from the traversing thread guide 1 guided and inserted into the thread guide 18. The auxiliary device can can be designed in a simple manner as a ramp parallel to Movement of the traversing thread guide 6 is introduced into the winding area. Thus, the thread 1 could be guided out of the traversing thread guide 6 automatically become. The ramp would advantageously be coupled to the thread guide 18, see above that the thread sliding on the ramp automatically into the guide groove of the Thread guide 18 occurs.

Während der Fadenführer 18 in der Übergabeebene positioniert ist, wird ein Abbindewickel 23 wulstartig auf der Spule 24 gewickelt. Um den Spulenwechsel durchzuführen, wird nun in der Aufwickeleinrichtung der Spulenhalter 26 derart verschwenkt, daß die Spule 24 sich von der Oberfläche der Treibwalze 29 löst. Die Spule 24 wird somit nicht mehr aktiv angetrieben. Der Faden 1 wird weiter als Abbindewulst 23 gewickelt. Nun wird eine seitlich zum Spulenbereich angeordnete Übergabeeinrichtung 42 aktiviert. Die Übergabeeinrichtung 42 besitzt einen Greifarm 43, der mit einem freien Ende die Übergabeebene durchdringt. Der Greifarm 43 ist an einer Schwenkachse 25 drehbar gelagert und wird über einen hier nicht gezeigten Antrieb parallel zur Übergabeebene bewegt. Der Greifarm 43 ist derart dimensioniert, daß das freie Ende des Greifarms 43 den Faden zwischen dem Fadenführer 18 und der Spule 24 ergreift und den Faden 1 in der Übergabeebene zu der Absaugeinrichtung 37 führt. Die Absaugeinrichtung 37 liegt hierbei innerhalb der durch das freie Ende des Greifarms 43 beschriebenen Bewegungsbahn. Damit wird erreicht, daß der Faden 1 in die Schneideinrichtung 38 eintaucht und durch das Messer 47 geschnitten wird. Kurz zuvor bzw. gleichzeitig gelangt der Faden 1 in die schlitzförmige Saugöffnung 46 des Absauganschlusses 39. Das Fadenende des zulaufenden Fadens wird somit unmittelbar nach dem Durchtrennen abgesaugt. Das lose Fadenende der Spule wird durch die auslaufende Spule 24 auf dem Abbindewickel 23 abgelegt. Die Übergabeeinrichtung 42 wird nach dem Durchtrennen des Fadens 1 in ihre Ausgangslage zurückbewegt.While the thread guide 18 is positioned in the transfer plane, a The binding coil 23 is wound in a bead-like manner on the coil 24. To the Carrying out bobbin changes is now carried out in the winding device Coil holder 26 pivoted such that the coil 24 is different from the Surface of the drive roller 29 releases. The coil 24 is therefore no longer actively driven. The thread 1 is further wound as a binding bead 23. Now a transfer device 42 is arranged laterally to the coil area activated. The transfer device 42 has a gripping arm 43, which with a free end penetrates the transfer level. The gripper arm 43 is on a pivot axis 25 is rotatably supported and is not one here shown drive moves parallel to the transfer plane. The gripper arm 43 is dimensioned such that the free end of the gripper arm 43 the thread grips between the thread guide 18 and the bobbin 24 and the thread 1 in the transfer level leads to the suction device 37. The suction device 37 lies within the free end of the gripping arm 43 described trajectory. This ensures that the thread 1 in the Cutting device 38 is immersed and cut by the knife 47. Shortly before or at the same time, the thread 1 reaches the slit-shaped one Suction opening 46 of the suction connection 39. The thread end of the incoming Thread is thus suctioned off immediately after cutting. That loose Thread end of the bobbin is through the outgoing bobbin 24 on the Tying winder 23 stored. The transfer device 42 is after the Cutting the thread 1 moved back to its starting position.

Bei der in Fig. 2 gezeigten Situation ist bereits ein Spulenwechsel erfolgt, und der kontinuierlich zugeführte Faden wird von der Absaugeinrichtung 37 und dem Fadenführer 18 geführt. Aufgrund der Übersichtlichkeit wurde in Fig. 2 auf die Darstellung der Übergabeeinrichtung verzichtet.In the situation shown in FIG. 2, the spool has already been changed, and the continuously fed thread is from the suction device 37 and the thread guide 18 out. Because of the clarity, Fig. 2 dispenses with the representation of the transfer device.

Der Faden 1 wird über die Saugöffnung 46 des Absauganschlusses 39 kontinuierlich mittels eines Saugstromes abgeführt. Die Spule 24 wurde durch eine neue Leerhülse ersetzt, die durch die Treibwalze 29 angetrieben wird. Um den Faden an die Leerhülse 13 zum Aufwickeln anzulegen, wird der Faden 1 von der Absaugeinrichtung 37 durch den Fadenführer 18 geführt. Der Fadenführer 18 wird durch den Antrieb 19 in eine Fangposition außerhalb des Spulbereichs geführt. Diese Fangposition des Fadenführers 18 ist derart gewählt, daß der Faden 1 schräg über die zur Hülse gewandte Stirnkante des Spanntellers 27 läuft. Zuvor wird die Hülse 13 durch die am Umfang anliegende Treibwalze 30 auf eine durch die Treibwalze vorgegebene Spuldrehzahl angetrieben.The thread 1 is fed through the suction opening 46 of the suction connection 39 continuously removed by means of a suction stream. The coil 24 was through replaced a new empty tube, which is driven by the drive roller 29. In order to apply the thread to the empty tube 13 for winding, the Thread 1 guided by the suction device 37 through the thread guide 18. The thread guide 18 is driven into a catch position by the drive 19 out of the winding area. This catch position of the thread guide 18th is selected such that the thread 1 obliquely across the sleeve Front edge of the clamping plate 27 runs. Previously, the sleeve 13 by the on Circumferential drive roller 30 to a predetermined by the drive roller Spindle speed driven.

Bei Verwendung eines Sensors 32 erzeugt dieser bei jedem Passieren der Fangnut 21 einen Umpuls, welcher der Steuereinrichtung 8 aufgegeben wird. Die Steuereinrichtung 8 weist eine Auswerteinrichtung auf, welche aus den pro Zeiteinheit eintretenden Impulsen die momentane Drehzahl des Spanntellers 27 und damit der Hülse 13 ermittelt. Gleichzeitig gibt jeder Impuls die Lage der Fangnut 21 an. Nachdem die Hülse 13 die Spuldrehzahl erreicht und die Fangnut 21 eine zum sicheren Fangen erforderliche Position aufweist, wird der Antrieb 19 der Steuereinrichtung 8 aktiviert, um den Fadenführer 18 in seine Fangposition zu bewegen. Der Faden 1 wird nun von der Fangeinrichtung 14 im Spannteller 27 gefangen.When a sensor 32 is used, it generates the each time it passes Catch groove 21 a pulse, which is given to the control device 8. The control device 8 has an evaluation device which consists of the the momentary speed of the Clamping plate 27 and thus the sleeve 13 determined. At the same time everyone gives Impulse the position of the catch groove 21. After the sleeve 13 the winding speed reached and the catch groove 21 a position required for safe catching has, the drive 19 of the control device 8 is activated to the Thread guide 18 to move to its catch position. Thread 1 is now caught by the catching device 14 in the clamping plate 27.

Nachdem der Faden 1 von der Fangeinrichtung 14 gefangen ist, wird der Faden durch eine zwischen der Fadenabsaugeinrichtung 37 und dem Spannteller 27 angeordnete Schneideinrichtung 45 geschnitten. Nach dem Fangen wird der Fadenführer 18 durch den Antrieb 19 aus der Fangposition ausgelenkt, um eine Fadenreservewicklung auf der Hülse abzulegen. Hierzu wird der Fadenführer 18 in Richtung Hülsenmitte bewegt. Nachdem die Fadenreservewicklung gelegt ist, wird der Faden 1 dem Changierfadenführer 6 übergeben. Hierzu könnte ebenfalls eine als Rampe ausgeführte Hilfseinrichtung eingesetzt werden. Die Aufwicklung beginnt nun mit einer neuen Spulenreise.After the thread 1 is caught by the catching device 14, the Thread through a between the thread suction device 37 and the Clamping device 27 arranged cutting device 45 cut. After this The thread guide 18 is caught by the drive 19 from the catching position deflected to deposit a thread reserve winding on the sleeve. For this the thread guide 18 is moved towards the center of the tube. after the Thread reserve winding is placed, the thread 1 is the traversing thread guide 6 passed. This could also be a ramp Auxiliary device can be used. The winding up now begins with a new spool trip.

In Fig. 3 und 4 ist ein weiteres Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung gezeigt, wie sie bei einer Aufwicklung in einer Texturiermaschine einsetzbar ist. Bei diesem Ausführungsbeispiel wird der Faden 1 zum Spulenwechsel, zum Fangen und zum Anwickeln durch den Changierfadenführer 6 geführt. Da der Aufbau der Aufwickelvorrichtung sich im wesentlichen nur durch die Changiereinrichtung zu der in Fig. 1 gezeigten Aufwickelvorrichtung unterscheidet, haben die Bauteile gleicher Funktion identische Bezugszeichen erhalten. Insoweit wird an dieser Stelle auch auf die Beschreibung zu Fig. 1 und Fig. 2 Bezug genommen.3 and 4 is a further embodiment of an inventive Device shown as in a winding in a Texturing machine can be used. In this embodiment, the Thread 1 for changing bobbins, for catching and for winding through the Traversing thread guide 6 out. Because the structure of the take-up reel itself essentially only by the traversing device to that in FIG. 1 Different winding device shown, the components have the same Function received identical reference numerals. So far at this point also refer to the description of FIGS. 1 and 2.

Die Changiereinrichtung 22 ist als sogenannte Riemenchangierung aufgebaut. Hierbei ist ein Changierfadenführer 6 an einem endlosen Riemen 33 befestigt. The traversing device 22 is constructed as a so-called belt traverse. Here, a traversing thread guide 6 is attached to an endless belt 33.

Der Riemen 33 wird zwischen zwei Umlenkrollen 34.1 und 34.2 parallel zur Hülse 13 geführt. In der Riemenebene ist eine vom Riemen teilumschlungene Antriebsrolle 35 parallel zu den Umlenkrollen 34.1 und 34.2 angeordnet. Die Antriebsrolle 35 ist auf einer Antriebswelle 44 eines Elektromotors 36 befestigt. Der Elektromotor 36 treibt die Antriebsrolle 35 oszillierend an, so daß der Changierfadenführer 6 in dem Bereich zwischen den Umlenkrollen 34.1 und 34.2 hin- und hergeführt wird. Der Elektromotor ist über die Steuereinrichtung 8 steuerbar. Die Steuereinrichtung 8 steht in Verbindung mit dem an dem Spulenhalter 26 angeordneten Sensor 32, der die Fangnut 21 der Fangeinrichtung 14 sensiert.The belt 33 is parallel to between two pulleys 34.1 and 34.2 Sleeve 13 out. In the belt plane there is a part wrapped around the belt Drive roller 35 arranged parallel to the deflection rollers 34.1 and 34.2. The Drive roller 35 is on a drive shaft 44 of an electric motor 36 attached. The electric motor 36 drives the drive roller 35 in an oscillating manner, so that the traversing thread guide 6 in the area between the deflection rollers 34.1 and 34.2 back and forth. The electric motor is about that Control device 8 controllable. The control device 8 is connected with the sensor 32 arranged on the coil holder 26, which detects the catch groove 21 of the catching device 14 sensed.

In den Figuren 3 und 4 ist die Aufwickelvorrichtung in verschiedenen Betriebssituationen gezeigt. In Fig. 3 ist die Aufwickelvorrichtung am Ende einer Spulreise gezeigt. Nachdem die Spule 24 zu Ende gewickelt ist, wird der Changierfadenführer 6 in eine Übergabeebene positioniert. In dieser Übergabeebene verharrt der Changierfadenführer 6. Auf der Spule 24 wird nun ein Abbindewickel 23 erzeugt. Gleichzeitig wird der Spulenhalter 26 mit der Spule 24 aus der Betriebsstellung verschwenkt. Nun tritt eine Übergabeeinrichtung 42 in Aktion, indem ein Greifarm 43 mit seinem freien Ende in den Fadenlauf zwischen der Vollspule 24 und dem Changierfadenführer 21 eingreift. Der Greifarm 43 wird aus einer Ruhestellung in eine Übergabestellung verschwenkt. Hierbei ergreift er den Faden 1 und führt den Faden in der Übergabestellung zur Absaugeinrichtung 37. In der Schneidvorrichtung 38 wird der Faden sodann geschnitten und von dem Absauganschluß 39 übernommen. Das lose Fadenende wird auf der Spule im Bereich der Abbindewickel gelegt. Nun kann die Spule 24 durch eine Leerhülse ausgetauscht werden. Hierbei ist von Vorteil, daß der Sensor an dem Spulenhalter befestigt ist und somit den Stillstand der Spule dadurch signalisiert, daß kein Impuls mehr erfolgt. Das Sensorsignal kann somit zur Aktivierung einer Wechselvorrichtung eingesetzt werden. Nachdem die Spule 24 durch eine Hülse ersetzt wurde, beginnt der Ablauf des Anlegens.In Figures 3 and 4, the winding device is different Operating situations shown. In Fig. 3 the winder is at the end a winding trip shown. After the coil 24 is wound to the end the traversing thread guide 6 is positioned in a transfer plane. In this The traversing thread guide 6 remains on the transfer plane now produces a binding wrap 23. At the same time, the bobbin holder 26 becomes the coil 24 pivoted from the operating position. Now one kicks Transfer device 42 in action by a gripper arm 43 with its free End in the thread course between the full spool 24 and the Traversing thread guide 21 engages. The gripper arm 43 becomes one Rest position pivoted into a transfer position. Here he takes hold of the Thread 1 and leads the thread in the transfer position to the suction device 37. The thread is then cut in the cutting device 38 and by the suction port 39 taken over. The loose thread end is on the Coil placed in the area of the binding reel. Now the coil 24 can an empty tube can be replaced. The advantage here is that the sensor is attached to the coil holder and thus the standstill of the coil signals that there is no more pulse. The sensor signal can thus Activation of a changing device can be used. After the coil 24 has been replaced by a sleeve, the process of laying on begins.

In Fig. 4 ist der Beginn des Anlegevorgangs gezeigt. Der kontinuierlich zugeführte Faden wird von der Absaugeinrichtung 37 und dem Changierfadenführer 6 geführt. Hierzu ist das Fadenende ineine Saugöffnung des Absauganschlusses 39 eingesogen. Der Changierfadenführer 6 wird in Richtung des Spanntellers 27 in eine Fangposition außerhalb des Spulbereichs geführt. Die Hülse 13 wird durch die am Umfang anliegende Treibwalze 29 auf eine durch die Treibwalze vorgegebene Spuldrehzahl angetrieben. Der Sensor 32 erzeugt bei jedem Passieren der Fangnut 21 einen Impuls, welcher der Steuereinrichtung 8 aufgegeben wird. Die Steuereinrichtung 8 weist eine Auswerteeinrichtung auf, welche aus der pro Zeiteinheit eintretenden Impulse die momentane Drehzahl des Zentriertellers und damit der Hülse ermittelt. Gleichzeitig gibt jeder Impuls die Lage der Fangnut 21 an. Nachdem die Hülse 13 die Spuldrehzahl erreicht und die Fangnut eine zum sicheren Fangen erforderliche Position aufweist, wird durch die Steuereinrichtung 8 der Elektromotor 6 derart gesteuert, daß der Elektromotor den Changierfadenführer 6 in die Fangposition bringt. Der Faden 1 kreuzt nun die Fangebene der Fangeinrichtung 14, so daß er von der Fangnut 21 gefangen wird. Der Faden 1 wird mit der Fangnut 21 gefangen und mit einem in der Fangeinrichtung bzw. dem Spannteller 27 integrierten Messer geschnitten. Ein derartiger Spannteller ist beispielsweise aus der EP 0 403 949 bekannt. Insoweit wird auf die genannte Druckschrift bezug genommen.4 shows the start of the application process. The continuously fed thread is from the suction device 37 and the Traversing thread guide 6 out. For this purpose, the thread end is in a suction opening of the suction port 39 sucked. The traversing thread guide 6 is in Direction of the clamping plate 27 into a catch position outside the winding area guided. The sleeve 13 is driven by the peripheral roller 29 driven to a spool speed predetermined by the drive roller. The Sensor 32 generates a pulse each time it passes through the catch groove 21 the control device 8 is abandoned. The control device 8 has one Evaluation device, which from the pulses occurring per unit of time the current speed of the centering plate and thus the sleeve is determined. At the same time, each pulse indicates the position of the catch groove 21. after the Sleeve 13 reaches the spool speed and the catch groove one for safe Catching required position is controlled by the control device 8 the electric motor 6 controlled so that the electric motor Traversing thread guide 6 brings in the catch position. Thread 1 now crosses the catch level of the catching device 14, so that it from the catch groove 21st is caught. The thread 1 is caught with the catch groove 21 and with a knife integrated in the catching device or the clamping plate 27 cut. Such a clamping plate is for example from EP 0 403 949 known. In this respect, reference is made to the publication mentioned.

Nach dem Fangen wird der Changierfadenführer 6 aus der Fangposition zum Spulbereich geführt. Hierbei wird der Faden 1 auf der Hülse 13 außerhalb des Spulbereichs zu einer Fadenreservewicklung gewickelt. Die Bildung der Fadenreservewicklung könnte hierbei durch einen in einer Position verharrenden Changierfadenführer 6 erfolgen. Dann weist die Fadenreservewicklung eine Anzahl von Parallelwicklungen auf. Der Changierfadenführer 6 kann aber auch mit einer durch den Elektromotor 36 bestimmten Geschwindigkeit zum Spulbereich geführt werden, so daß nebeneinanderliegende Windungen in der Fadenreservewicklung erzeugt werden. Sobald der Fadenführer den Spulbereich erreicht, beginnt die Spulreise. Der Changierfadenführer 6 wird sodann innerhalb des Spulbereichs durch die Changiereinrichtung 22 oszillierend angetrieben. Der anwachsende Spulendurchmesser der Spule 24 wird durch eine Schwenkbewegung des Spulenhalters 26 ermöglicht. Der Spulenhalter 26 weist hierzu Kraftgeber auf, die einerseits einen zum Antrieb der Spule erforderlichen Anpreßdruck zwischen der Spule 24 und der Treibwalze 29 erzeugen und andererseits eine Schwenkbewegung des Spulenhalters 26 ermöglichen. After catching, the traversing thread guide 6 becomes from the catching position Led winding area. Here, the thread 1 on the sleeve 13 outside of the winding area wound into a thread reserve winding. The formation of the Thread reserve winding could be done by one in one position persistent traversing thread guide 6. Then the Thread reserve winding on a number of parallel windings. The Traversing thread guide 6 can, however, also be operated with one by the electric motor 36 certain speed to the winding area so that adjacent turns generated in the thread reserve winding become. As soon as the thread guide reaches the winding area, the begins Winding cycle. The traversing thread guide 6 is then within the winding area driven oscillating by the traversing device 22. The growing Coil diameter of the coil 24 is by a pivoting movement of the Coil holder 26 allows. For this purpose, the coil holder 26 has force transmitters, on the one hand a contact pressure required to drive the coil generate between the coil 24 and the drive roller 29 and on the other hand Allow pivotal movement of the bobbin holder 26.
