Abstract

The invention relates to a device and method for guiding and cutting a continuously tapering thread (1) when changing bobbins in a winding device. To this end, the thread is guided essentially parallel to a bobbin or to a tube (13) by means of a moveable thread guide (18), said bobbin or tube being driven by a slubbing roller (29). A deflecting device (2) and a suction device (37) are arranged downstream from the thread guide (18), said suction device being comprised of a pneumatic suction connection (46) and of a cutting device (47). The suction device (37) interacts with a transferring device in order to cut the thread when changing bobbins and in order to take up the free thread end of the tapering thread. In order to enable a gentle processing of the thread when changing bobbins, the thread guide (18) is arranged, in the flow of the thread, in front of the driven tube (13), and the deflecting device (2) as well as the suction device (37) are arranged behind said driven tube. In order to catch and wind the thread onto a new tube (13) which is driven by a slubbing roller (29), the thread is guided by the deflecting device (2) and by the thread guide (18) outside of the contact area between the tube (13) and the slubbing roller (29).

In Textilmaschinen wird beispielsweise ein gekräuselter Faden kontinuierlich zu einer Spule gewickelt. 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.In textile machines, for example, a crimped thread is continuously closed a coil wound. After the bobbin has finished winding, a Bobbin change. For this it is necessary that the thread is cut first is so that the full bobbin with loose thread end against a new empty tube can be changed. The thread end of the continuously running thread during the change by means of a pneumatic suction device recorded and discharged. After the bobbin change, the Thread caught by a catcher and on the new tube initially wound.

Bei der aus der EP 0 311 827 bekannten Vorrichtung und bei dem bekannten Verfahren wird der Faden mittels eines beweglichen Fadenführers nach der Fertigstellung der Spule außerhalb des Spulbereiches zu einer seitlich neben dem Spulbereich angeordneten Absaugeinrichtung geführt. Nachdem der Spulenwechsel erfolgt ist und die neue Hülse bereit ist zum Fangen, wird der Fadenführer wieder in den Spulbereich verschwenkt. Zur Übergabe bzw. zum Fangen wird der Faden mittels einer Übergabeeinrichtung zwischen der Absaugeinrichtung und dem Fadenführer ausgelenkt und der Fangeinrichtung zum Fangen angeboten. In the device known from EP 0 311 827 and in the known The thread is moved by means of a movable thread guide according to the Completion of the bobbin outside of the bobbin area to a side next to the Exhaust device arranged winding area. After the The bobbin has been changed and the new tube is ready to be caught Thread guide pivoted back into the winding area. For handover or The thread is caught by means of a transfer device between the Suction device and the thread guide deflected and the catching device for Catch offered.

Die bekannte Vorrichtung und das bekannte Verfahren besitzen den Nachteil, daß am Ende der Spulreise das lose Fadenende auf der fertiggestellten Spule undefiniert anliegt, was insbesondere bei der Weiterverarbeitung das Auffinden des losen Fadenendes erschwert.The known device and the known method have the disadvantage that at the end of the bobbin trip, the loose thread end on the finished bobbin is undefined, which is particularly important for further processing when it is found of the loose thread end difficult.

Des weiteren führt die Auslenkung des Fadens durch die Übergabeeinrichtung zum Fangen des Fadens zu erheblichen Umschlingungen, die im Verhältnis zu der Aufwickelspannung zu größeren Zugkraftschwankungen im Faden führen. Derartige Zugkraftschwankungen können bei vorgeschalteten Förderelementen zu einer Wicklerbildung führen.Furthermore, the deflection of the thread leads through the transfer device to catch the thread to significant wraps that are in relation to the winding tension lead to greater fluctuations in tensile force in the thread. Such fluctuations in tensile force can occur with upstream conveying elements lead to a winder formation.

Die FR 22 47 906 beschribt eine Vorrichtung zum Schneiden eines Fadens, bei der ein Fadenführer hinter einer angetriebenen Walze angeordnet ist.FR 22 47 906 describes a device for cutting a thread a thread guide is arranged behind a driven roller.

Es ist Aufgabe der Erfindung, eine Vorrichtung und ein Verfahren der eingangs genannten Art derart zu schaffen, daß während des Spulenwechsel beim Führen und Fangen des Fadens und beim Anwickeln des Fadens eine möglichst schonende Fadenführung gewährleistet wird.It is an object of the invention, an apparatus and a method of the beginning to create the type mentioned in such a way that during the change of bobbin when guiding and catching the thread and when winding the thread one if possible gentle thread guidance is guaranteed.

Ein weiteres Ziel der Erfindung ist es, nach dem Schneiden des Fadens zu gewährleisten, daß das lose Fadenende am Abbindewulst der Vollspule anliegt und daß der laufende Faden ohne wesentliche Verschlappung an eine neue Hülse angelegt wird.Another object of the invention is to cut after the thread Ensure that the loose end of the thread lies against the binding bead of the full bobbin and that the running thread on a new sleeve without substantial slack is created.

Die Erfindung zeichnet sich dadurch aus, daß der Fadenführer und die Absaugeinrichtung beim Beginn des Spulenwechsels innerhalb des Spulbereiches angeordnet sind. Der Spulbereich ist hierbei der Bereich auf der Hülse, der von dem changierten Faden überdeckt wird. Damit kann der Faden mit relativ geringer Auslenkung geschnitten und von der Fadenabsaugung übernommem werden, so daß während der Wechselphase keine wesentlichen Fadenzugkraftschwankungen auftreten. Die Absaugeinrichtung ist hierbei vorzugsweise ortsfest angeordnet. Bei einer im wesentlichen parallel zur Spule beweglich ausgeführten Absaugeinrichtung besteht die Möglichkeit, das lose Fadenende mit dem Abbindewulst an einer beliebigen Position innerhalb des Spulbereiches zu plazieren. Durch die zwischen der Absaugeinrichtung und dem Fadenführer vorgesehene Umlenkeinrichtung ist eine hohe Flexibilität in der Gestaltung der Fangeinrichtung gegeben. Zudem verhindert die Umlenkeinrichtung, daß der zur Absaugeinrichtung laufende Faden nicht zwischen den Oberflächen einer neuen Hülse und der Treibwalze geklemmt wird. Der Faden wird ohne zu verschlappen von der Vollspule zu einer neuen Hülse übergeben. Ein weiterer Vorteil der Erfindung liegt darin, daß zum Fangen der Faden zu beiden Seiten der Fangeinrichtung geführt ist und somit eine sehr hohe Fangsicherheit erreicht wird.The invention is characterized in that the thread guide and Suction device at the beginning of the bobbin change within the bobbin area are arranged. The winding area is the area on the tube that of the covered thread is covered. This allows the thread to be relatively low Deflection cut and taken over by the thread suction, so that there are no significant thread tension fluctuations during the change phase occur. The suction device is preferably arranged stationary. at one designed to be movable essentially parallel to the coil Suction device there is the possibility of the loose thread end with the The setting bead is closed at any position within the winding area place. By between the suction device and the thread guide The intended deflection device is highly flexible in the design of the Giving device given. In addition, the deflection device prevents the Suction device running thread not between the surfaces of a new one Sleeve and the drive roller is clamped. The thread becomes tangle-free transferred from the full spool to a new tube. Another advantage of Invention is that for catching the thread on both sides of the Catch device is guided and thus a very high level of safety is achieved.

Die besonders vorteilhafte Weiterbildung der Vorrichtung gemäß Anspruch 2 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 Umlenkeinrichtung läßt sich zudem die Auslenkung des Fadens minimieren.The particularly advantageous development of the device according to claim 2 enables the thread to move without further aids simply by moving the Thread guide is caught in the catching device. For this, the thread is only in Longitudinal direction deflected parallel to the sleeve. With an additional rectified movement of the deflection 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. Zudem ist die Anordnung des Fadenführers, der Umlenkeinrichtung und der Fangeinrichtung derart vorteilhaft, daß der Faden und der Spannteller eine gleichgerichtete Bewegung ausführen. Damit tritt keine Verschlappung und damit keine überhöhte Fadenspannungsschwankung beim Fangen auf. 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 tensioning plates, the thread can be catch easily. To do this, thread the thread in an oblique course over the Front edge of the tension plate guided so that the thread in one in the front edge of the clamping plate inserted automatically falls. In addition, the Arrangement of the thread guide, the deflection device and the catching device so advantageous that the thread and the tension plate are rectified Carry out movement. So there is no waste and therefore no excessive Thread tension fluctuation when catching.

Da die Umlenkeinrichtung während des Spulenwechsels nur kurzzeitig eine Führung des Fadens übernimmt, ist die Ausbildung der erfindungsgemäßen Vorrichtung gemäß Anspruch 4 besonders vorteilhaft. Hierbei besteht die Umlenkeinrichtung aus einem beweglichen Umlenkfadenführer und einem steuerbaren Antrieb. Der Umlenkfadenführer wird dabei mittels des Antriebes aus einer Ruhestellung außerhalb des Fadenlaufs heraus bewegt. In der Phase, in welcher der Faden auf einfache Weise durch die Übergabeeinrichtung von der Vollspule in die Absaugeinrichtung geführt wird und während des Wickelns vom Abbindewulst sowie zu Beginn des Spulenwechsels ist eine Führung des Fadens nur durch den Fadenführer bzw. nur durch den Fadenführer und die Absaugeinrichtung möglich. Der Umlenkfadenführer bleibt zunächst in seiner Ruhestellung. Es treten keine wesentlichen Auslenkungen des Fadens und damit keine wesentlichen Umschlingungen auf. Erst kurz bevor die neue Hülse in Kontakt mit der Treibwalze gebracht wird, wird der Umlenkfadenführer durch den Antrieb aktiviert, um den Faden zu erfassen und auszulenken. Die Bewegung des Umlenkfadenführers kann vorteilhaft mit der Bewegung des Fadenführers zur Führung des Fadens in einem Fangbereich derart koordiniert werden, daß beispielsweise die Ansteuerung der Antriebe durch eine gemeinsame Steuereinrichtung vorgenommen wird. Damit läßt sich die Fadenführung im weiteren Verlauf des Spulenwechsels besonders schonend ausführen. Es ist jedoch auch möglich, den Umlenkfadenführer unabhängig von dem Fadenführer vor der angetriebenen Hülse in Richtung zum Hülsenrand zu bewegen.Since the deflection device only briefly during the coil change Taking control of the thread is the training of the invention Device according to claim 4 particularly advantageous. Here is the Deflection device from a movable deflection thread guide and one controllable drive. The deflecting thread guide is made by means of the drive moved out of a rest position outside the thread path. In the phase in which the thread in a simple manner by the transfer device from the Full coil is guided into the suction device and during winding from Binding bead and at the beginning of the bobbin change is a guide of the thread only by the thread guide or only by the thread guide and Suction device possible. The guide thread guide remains in its first Rest. There are no significant deflections of the thread and thus no significant wrapping. Just before the new sleeve in Is brought into contact with the drive roller, the guide thread is guided by the Actuator activated to catch and deflect the thread. The movement of the Deflecting thread guide can be advantageous with the movement of the thread guide Guide the thread in a catch area be coordinated such that for example the actuation of the drives by a common one Control device is made. So that the thread guide in carry out the further course of the bobbin change particularly gently. However, it is also possible to guide the deflecting thread guide independently of the thread guide to move the driven sleeve towards the sleeve edge.

Bei einer besonders vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung nach Anspruch 5 wird der Umlenkfadenführer zwischen der Ruhestellung und einer Umlenkstellung bewegt. Der Umlenkfadenführer durchläuft dabei eine zum Fadenlauf querliegende Bewegungsbahn, so daß der Umlenkfadenführer mit einer die Fadenlaufebene durchdringenden Führungskante den Faden sicher ergreifen und auslenken kann. Der Vorteil dieser Ausbildung liegt darin, daß der Faden aus definierter Position heraus der Fangeinrichtung zum Fangen angeboten werden kann. Eine überlagerte Relativbewegung zwischen Fangeinrichtung und Umlenkfadenführer ist in diesem Fall nicht gegeben.In a particularly advantageous embodiment of the invention Apparatus according to claim 5, the guide thread between the Rest position and a deflection position moves. The guide thread guide passes through a trajectory transverse to the thread path, so that the Deflection thread guide with a guide edge penetrating the thread running plane can seize and deflect the thread safely. The advantage of this training is that the thread from the defined position of the safety gear to Catch can be offered. A superimposed relative movement between In this case, there is no safety gear and deflection thread guide.

Bei einer besonders vorteilhaften Weiterbildung der Vorrichtung gemäß Anspruch 6 sind der Fadenführer und die Absaugeinrichtung in einer Übergabeebene angeordnet, so daß das lose Fadenende an der Vollspule sicher auf dem Abbindewickel abgelegt werden kann. Des weiteren kann durch einfache Schwenkbewegung der Übergabeeinrichtung der Faden in die Schneideinrichtung der Absaugeinrichtung hineingeführt werden. 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 des weiteren den Vorteil, daß beim Abheben der Spule von der Treibwalze der Faden durch die Übergaheeinrichtung 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 6 are the thread guide and the suction device in a transfer plane arranged so that the loose end of the thread on the full spool securely on the Tying wrapping can be stored. Furthermore, by simple Swiveling movement of the thread transfer device into the cutting device the suction device. 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 Yarn guide. This training also has the advantage that when Lifting the bobbin from the drive roller of the thread through the transfer device remains safely guided in the thread guide. The transfer level is here preferably formed as the normal plane of the coil and contains the Tying reel of the spool.

Die Ausführung der Vorrichtung gemäß Anspruch 7 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 7 ensures that the thread before entering the cutting device from the pneumatic Suction port is detected. The thread end of the incoming thread is thus safely taken after cutting in the cutter and dissipated. For this purpose, the cutting device preferably has a knife blade on that cooperates with the gripper arm of the transfer device such that the thread is cut cleanly and quickly by the knife blade.

Um den laufenden Faden sicher in die Saugöffnung des Absauganschlusses zu führen, ist dieser gemäß Anspruch 8 vorteilhaft geschlitzt ausgeführt.To securely feed the running thread into the suction opening of the suction connection lead, this is advantageously designed slotted according to claim 8.

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 sleeve and the movement of the Thread guide executes at variable speed regardless of direction. In this case, the drive could be designed as a linear drive, for example his.

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, the thread guide executed as a traversing thread guide of a traversing device. This can the traversing thread guide the thread outside and inside the winding area Run lengthways parallel to the sleeve. This version has the advantage that no additional control unit for controlling the traversing device is required. All operations during winding, during Bobbin change and while catching are controlled by a control device 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. Zunächst wird auf der Vollspule ein Abbindewulst gewickelt, wobei die Vollspule bereits von der Treibwalze abgehoben wird.. 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. Bevor die neue Hülse auf die Treibwalze gesetzt wird, führt der Changierfadenführer und die Umlenkeinrichtung den Faden aus dem Kontaktbereich zwischen der Hülse und der Treibwalze. Die Hülse wird auf die Treibwalze aufgesetzt und 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.After the thread has been caught and wound on the tube, the actual winding travel, i.e. winding the spool. After the coil is completed, the thread from the Suction device taken over. For this, the thread leading remains Traversing thread guide stand on a transfer level. First, on the Full coil wound a binding bead, the full coil already from the Driving roller is lifted .. The transfer device then leads the thread in the suction device. Now that the bobbin has been changed and the Empty sleeve in the bobbin holder between the clamping plates begins the threading. Before the new sleeve is placed on the drive roller, the traversing thread guide and the deflection device guides the thread out of the Contact area between the sleeve and the drive roller. The sleeve is on the Driving roller attached and at a speed required for the application accelerated. As soon as the speed is reached, the drive of the Traversing thread guide activated, and the traversing thread guide leads the thread in a catch position in which the thread is inclined over a catch plane of the Catcher runs, for example an end edge of the clamping plate.

Das erfindungsgemäße Verfahren zeichnet sich besonders durch schnelle und präzise Spulenwechsel aus. Insbesondere durch die Führung des Fadens vor und hinter der Fangeinrichtung läßt sich der Faden sehr genau positionieren, so daß der Faden sicher und ohne wesentliche Verschlappung von der Fangeinrichtung gefangen wird.The inventive method is particularly characterized by fast and precise bobbin changes. In particular by guiding the thread in front of and behind the catching device, the thread can be positioned very precisely, so that the thread securely and without substantial slack from the catching device is caught.

Die besonders vorteilhaften Verfahrensvarianten nach Anspruch 12 oder 13 lassen eine große Gestaltungsfreiheit für die Fangeinrichtung zu. Zudem können damit unnötige Fadenumschlingungen vermieden werden.Leave the particularly advantageous method variants according to claim 12 or 13 great freedom of design for the safety gear. You can also use it unnecessary thread wrapping can be avoided.

Die Verwendung der erfindungsgemäße Vorrichtung in einer Falschdralltexturiermaschine ist besonders vorteilhaft, da Falschdralltexturiermaschine über eine Vielzahl von Aufwickelvorrichtungen verfügen, die ohne manuelle Bedienung nach jeder gewickelten Spule einen Spulenwechsel ausführen. Eine mit der erfindungsgemäßen Vorrichtung ausgestattet Falschdralltexturiermaschine besitzt somit die bereits zuvor beschriebenen Vorteile.The use of the device according to the invention in a False twist texturing machine is particularly advantageous because False twist texturing machine via a variety of winding devices have one without manual operation after each wound coil Change the bobbin. One with the device according to the invention The false twist texturing machine already has it described advantages.

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.1 and Fig. 2 is a first embodiment of an inventive Device shown within a take-up device, such as, for example can be used in a texturing machine. The following description therefore applies to FIGS. 1 and 2, unless stated otherwise.

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 spool holder 26 which a pivot axis 40 is mounted. The pivot axis 40 is at one Machine frame 41 attached. At the free ends of the fork-shaped Coil holder 26, two opposing clamping plates 27 and 28 are rotatable stored. Between the clamping plates 27 and 28 is a sleeve 13 for receiving a coil tensioned. For this purpose, the clamping plates 27 and 28 each have one conical centering shoulder that partially protrudes into the sleeve end. In order to the sleeve 13 is centered between the clamping plates 27 and 28. On the surface the sleeve 13 is a drive roller 29. The drive roller 29 is on one Drive shaft 31 attached. The drive shaft 31 is at one end with the Roller motor 30 coupled. The roller motor 30 drives the drive roller 29 in the substantially constant speed. The sleeve 13 is now over friction driven by the drive roller 29 to a winding speed, so that the thread 1 is wound on the sleeve 13 into a coil. This is in front of the drive roller 29 a traversing thread guide 6 is arranged in the thread path. The traversing thread guide is coupled to a traversing drive which guides the traversing thread guide 6 drives oscillating within the winding area. The traversing drive can for example, formed by a reverse thread shaft or a belt drive his.

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.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 13th 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.

Die Steuereinrichtung 8 dient ebenfalls zur Ansteuerung einer Umlenkeinrichtung 2. Die Umlenkeinrichtung 2 ist auf der zum Fadenführer 18 gegenüberliegenden Seite der Treibwalze 29 bzw. einer an der Treibwalze anliegenden Hülse 13 angeordnet. Die Umlenkeinrichtung 2 weist einen Antrieb 4 auf, der mit der Steuereinrichtung 8 verbunden ist. Der Antrieb 4 ist mit einem Umlenkfadenführer 3 gekoppelt. Der Umlenkfadenführer 3 wird durch eine L-förmige Stange gebildet. Ein Schenkel des Umlenkfadenführers 3 ist mit dem Antrieb 4 verbunden, der bei Aktivierung eine Drehbewegung auf den Umlenkfadenführer 3 ausübt. Der freie Schenkel des Umlenkfadenführers 3 weist eine Führungskante 5 auf, die durch Drehung des Umlenkfadenführers 3 aus einer Ruhestellung in eine Betriebsstellung verschwenkbar ist. Dabei durchläuft der Umlenkfadenführer 3 eine Bewegungsbahn, die den Fadenlauf eines in einer Absaugeinrichtung 37 einlaufenden Fadens 1 kreuzt. In Fig. 1 ist die Umlenkeinrichtung 2 mit dem Umlenkfadenführer 3 in der Ruhestellung dargestellt. In Fig. 2 ist die Umlenkeinrichtung 2 mit dem Umlenkfadenführer 3 in der Betriebsstellung gezeigt.The control device 8 also serves to control a deflection device 2. The deflection device 2 is on the opposite to the thread guide 18 Side of the drive roller 29 or a sleeve 13 abutting the drive roller arranged. The deflection device 2 has a drive 4, which with the Control device 8 is connected. The drive 4 is with a Deflection thread guide 3 coupled. The guide thread guide 3 is by an L-shaped Rod formed. One leg of the guide thread 3 is with the Drive 4 connected, the rotary motion when activated on the Deflection thread guide 3 exercises. The free leg of the guide thread guide 3 has a leading edge 5, which by rotating the guide guide 3 from a Rest position is pivotable into an operating position. The runs through Deflecting thread guide 3 a path of movement that the thread run one in one Suction device 37 crosses incoming thread 1. 1 is the Deflection device 2 with the deflection thread guide 3 in the rest position shown. 2, the deflection device 2 with the deflection thread guide 3 is in shown the operating position.

Auf der zur Changierung gegenüberliegenden Seite zur Hülse 13 bzw. zur Treibwalze 29 ist die 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 or for Driving roller 29, the suction device 37 is arranged. The suction device 37 here consists of a cutting device 38 and a suction connection 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 a transfer plane positioned. At the same time, one is not described here Auxiliary device of the thread 1 out of the traversing thread guide 1 and in the Thread guide 18 inserted. The auxiliary device can do this in a simple manner be designed as a ramp parallel to the movement of the traversing thread guide 6 is introduced into the winding area. So that the thread 1 could automatically from the Traversing thread guide 6 are guided. The ramp would be beneficial with that Thread guide 18 coupled so that the thread sliding on the ramp automatically in 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. Die Umlenkeinrichtung 2 verharrt während dieser Phase in ihrer Ruhestellung, so daß der Umlenkfadenführer 3 keinen Fadenkontakt hat.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 change the bobbin to be carried out, the bobbin holder 26 is now such in the winding device pivots that the coil 24 detaches from the surface of the drive roller 29. The coil 24 is thus no longer actively driven. Thread 1 continues wound as a binding bead 23. Now one becomes the side of the coil area arranged transfer device 42 activated. The transfer device 42 has a gripper arm 43 which has the free end of the transfer plane penetrates. The gripping arm 43 is rotatably mounted on a pivot axis 25 and is moved parallel to the transfer level via a drive, not shown here. The gripping arm 43 is dimensioned such that the free end of the gripping arm 43 the Grips thread 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 that described by the free end of the gripping arm 43 Trajectory. This ensures that the thread 1 in the cutting device 38 immersed and cut by the knife 47. Shortly before or at the same time the thread 1 enters the slit-shaped suction opening 46 of the Suction port 39. The thread end of the incoming thread is thus aspirated immediately after cutting. The loose thread end of the bobbin is deposited on the binding reel 23 by the outgoing coil 24. The Transfer device 42 is in her after cutting the thread 1 Starting position moved back. The deflection device 2 remains during this Phase in their rest position, so that the guide thread guide 3 none Thread contact.

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 Thread guide 18 out. For reasons of clarity, the Representation of the transfer device dispensed with.

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 die Umlenkeinrichtung 2 und den Fadenführer 18 geführt. Der Fadenführer 18 wird durch den Antrieb 19 in eine Position außerhalb des Spulbereichs geführt. Kurz vorher oder gleichzeitig wird der Antrieb 4 der Umlenkeinrichtung 2 über die Steuereinrichtung 8 aktiviert. Daraufhin wird der Umlenkfadenführer 3 aus seiner Ruhestellung verschwenkt und gelangt mit seiner Führungskante 5 in den Fadenlauf des Fadens 1. Der Faden 1 wird durch die Führungskante 5 des Umlenkfadenführers 3 mitgeführt und ausgelenkt. Nachdem der Umlenkfadenführer 3 seine Betriebsstellung erreicht hat, gleitet der Faden 1 an der Führungskante 5 des Umlenkfadenführers 3 bis zur Anlage, so daß der Faden 1 in einer Umlenkposition geführt ist. Der zulaufende Faden 1 wird durch den Fadenführer 18 und die Umlenkeinrichtung 2 außerhalb des Spulbereichs geführt. Von der Umlenkeinrichtung 2 läuft der Faden 1 weiterhin in die Absaugeinrichtung 37 ein und wird kontinuierlich abgeführt.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. Around to put the thread on the empty tube 13 for winding, the thread 1 of the suction device 37 through the deflection device 2 and the thread guide 18th guided. The thread guide 18 is moved into a position outside by the drive 19 of the winding area. Shortly before or at the same time, the drive 4 becomes the Deflection device 2 activated via the control device 8.
