Description

Die Erfindung betrifft eine Vorrichtung zum Aufwickeln eines Fadens mit einem beweglichen Spulenhalter gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for winding a thread with a movable bobbin holder according to the preamble of claim 1.

Eine gattungsgemäße Vorrichtung zum Aufwickeln eines Fadens geht beispielsweise aus der WO 2004/035446 A1 hervor.A generic device for winding a thread goes for example from the WO 2004/035446 A1 forth.

Die gattungsgemäße Vorrichtung zum Aufwickeln eines Fadens wird üblicherweise in Textilmaschinen eingesetzt, um einen Faden kontinuierlich zu einer Spule aufzuwickeln. Hierzu ist es üblich, dass ein zulaufender Faden am Ende des Prozesses möglichst ohne Unterbrechung zu einer Spule gewickelt werden kann. Insoweit ist das Auswechseln einer Vollspule möglichst automatisiert auszuführen. Die bekannte Aufwickelvorrichtung weist somit einen beweglichen Spulenhalter auf, der die auf eine Hülse gewickelte Spule zwischen zwei Klemmtellern hält. Damit die an dem Spulenhalter gehaltene Spule durch eine leere Hülse ersetzt werden kann, muss der gewickelte Faden von der Vollspule getrennt, während des Spulenwechsels kontinuierlich aufgenommen und zum Wickeln einer neuen Spule neu angelegt werden. Hierzu weist die bekannte Aufwickelvorrichtung eine Hilfseinrichtung auf, die zur Fadenführung an einem schwenkbaren Träger gehalten sind. Der Träger hält an einem frei auskragenden Ende einen Saugrüssel, der über einen Saugkanal mit einer Absaugeinrichtung verbunden ist. Am freien Ende des Saugrüssels ist eine Sauöffnung zur Aufnahme des Fadens ausgebildet. Des Weiteren sind an dem Schwenkarm verschiebbare Fadenführer und eine Schneideinrichtung angeordnet, die ein Durchtrennen und ein Übernehmen des Fadens sowie ein Abgeben des Fadens ausführen. Hierbei lässt sich der Schenkarm in unterschiedliche Positionen relativ zum Spulenhalter anordnen.The generic device for winding a thread is usually used in textile machines to continuously wind a thread into a bobbin. For this purpose, it is customary that a tapering thread can be wound into a bobbin without interruption at the end of the process, if possible. In this respect, the replacement of a full spool should be carried out as automatically as possible. The known winding device thus has a movable spool holder which holds the spool wound on a sleeve between two clamping plates. So that the bobbin held on the bobbin holder can be replaced by an empty tube, the wound thread must be separated from the full bobbin, continuously picked up during the bobbin change, and put on again to wind a new bobbin. For this purpose, the known winding device has an auxiliary device which is held on a pivotable carrier for thread guidance. The carrier holds a suction nozzle at a freely projecting end, which is connected to a suction device via a suction channel. A suction opening for receiving the thread is formed at the free end of the suction nozzle. Furthermore, slidable thread guides and a cutting device are arranged on the swivel arm, which cut and take over the thread and discharge the thread. Here, the arm can be arranged in different positions relative to the spool holder.

Durch EP 1 428 783 A1 ist eine Vorrichtung zum Aufwickeln eines Fadens mit einem beweglichen Spulenhalter, der zwei gegenüberliegende Klemmteller zum Spannen einer Hülse aufweist, mit einer dem Spulenhalter zugeordneten antreibbaren Treibwalze und mit einer Changiereinrichtung, die einen oszillierend angetriebenen Fadenführer (9) aufweist, bekannt. Es ist einer der Treibwalze im Fadenlauf vorgeordnete Hilfseinrichtung zur Führung des Fadens bei einem Spulenwechsel vorgesehen. Die Hilfseinrichtung weist einen mit einer Absaugeinrichtung verbundenen Saugrüssel mit einem Saugkanal auf,
In Praxis wird nun versucht, die Spulenwechsel in möglichst kurzen Unterbrechungszeiten zu realisieren. Insoweit sind schnelle und präzise Bewegungen der Hilfseinrichtungen erforderlich, um möglichst kurze Unterbrechungszeiten zu realisieren. Bei der bekannten Vorrichtung zum Aufwickeln eines Fadens besteht jedoch das Problem, dass die Hilfseinrichtung am auskragenden Ende eines Schwenkarmes getragen wird und somit der Schwenkarm eine hohe Massenträgheit aufweist. Damit lassen sich jedoch nur bedingt schnelle und präzise Positionswechsel ausführen. Zudem sind leistungsstarke Schwenkantriebe erforderlich, um die gesamte Hilfseinrichtung zu bewegen.By EP 1 428 783 A1 A device for winding a thread with a movable bobbin holder, which has two opposing clamping plates for tensioning a sleeve, with a drivable drive roller assigned to the bobbin holder and with a traversing device which has an oscillatingly driven thread guide (9), is known. An auxiliary device for guiding the thread when changing the bobbin is provided upstream of the drive roller in the thread path. The auxiliary device has a suction nozzle connected to a suction device with a suction channel,
In practice, attempts are now being made to change the bobbin in the shortest possible interruption times. In this respect, fast and precise movements of the auxiliary devices are required in order to achieve the shortest possible interruption times. In the known device for winding a thread, however, there is the problem that the auxiliary device is carried on the projecting end of a swivel arm and thus the swivel arm has a high mass inertia. However, this means that changes in position can only be made quickly and precisely to a limited extent. Powerful rotary actuators are also required to move the entire auxiliary device.

Es ist daher Aufgabe der Erfindung, die gattungsgemäße Vorrichtung zum Aufwickeln eines Fadens derart weiterzubilden, dass die Hilfseinrichtung schnelle und präzise Fadenführungen ermöglicht.It is therefore an object of the invention to develop the generic device for winding a thread in such a way that the auxiliary device enables fast and precise thread guides.

Diese Aufgabe wird erfindungsgemäß dadurch eine Vorrichtung zum Aufwickeln eines Fadens mit den Merkmalen des Anspruchs 1 gelöst
Vorteilhafte Weiterbildungen der Erfindung sind durch die Merkmale und Merkmalskombinationen der jeweiligen Unteransprüche definiert.According to the invention, this object is achieved by a device for winding a thread with the features of claim 1
Advantageous developments of the invention are defined by the features and combinations of features of the respective subclaims.

Die Erfindung basiert auf der Erkenntnis, dass die Fadenführung während des Spulenwechsels im Wesentlichen durch den Saugrüssel bestimmt ist, der an seinem Saugende den Faden führt. Somit ist die Positionierung des Saugrüssels zur Übernahme des Fadens nach einem Durchtrennen des Fadens von der Vollspule und die Übergabe des Fadens zum Start einer neuen Wicklung maßgeblich für die Fadenführung. Die direkte Anbindung des Saugrüssels an einen Drehantrieb hat den besonderen Vorteil, dass beliebige Positionen mit dem Saugende des Saugrüssels exakt angesteuert werden können. Damit wird insbesondere die Sicherheit beim Übernehmen des Fadens und beim Abgeben des Fadens wesentlich erhöht.The invention is based on the knowledge that the thread guide during the bobbin change is essentially determined by the suction nozzle, which guides the thread at its suction end. The positioning of the suction nozzle to take over the thread after cutting the thread from the full bobbin and the transfer of the thread at the start of a new winding are decisive for the thread guidance. The direct connection of the suction nozzle to a rotary drive has the particular advantage that any position can be controlled precisely with the suction end of the suction nozzle. In particular, the safety when taking over the thread and when releasing the thread is significantly increased.

Damit die in der Vorrichtung vorgesehene Positionen zur Übernahme des Fadens und zur Abgabe des Fadens in einfacher Art und Weise erreicht werden können, ist des Weiteren vorgesehen, dass der Saugrüssel zwischen dem Anschlussende und dem Saugende eine Rohrkrümmung aufweist, wobei ein Längenabschnitt mit dem Saugende länger ist als ein Längenabschnitt mit dem Anschlussende und wobei der Längenabschnitt mit dem Saugende im Sinne eines Uhrzeigers bewegbar ist. Damit lässt sich das Saugende des Saugrüssels ohne zusätzliche Antriebe in die entsprechenden Positionen führen. Das Saugende des Saugrüssels lässt sich allein durch den Drehantrieb wie das Ende eines Uhrzeigers in die verschiedenen Positionen überführen.In order that the positions provided in the device for taking over the thread and for dispensing the thread can be achieved in a simple manner, it is further provided that the suction nozzle has a pipe curvature between the connection end and the suction end, a length section with the suction end being longer is as a longitudinal section with the connection end and the longitudinal section with the suction end is movable in the sense of a clockwise hand. This allows the suction end of the proboscis to be guided into the corresponding positions without additional drives. The suction end of the proboscis can be transferred to the different positions by the rotary drive like the end of a clock hand.

Das Saugende des Saugrüssels lässt sich durch den Drehantrieb zwischen einer Ruheposition, einer Übernahmeposition und einer Übergabeposition positionieren, wobei in der Übernahmeposition der Saugrüssel quer zum Fadenlauf des zulaufenden Fadens ausgerichtet ist und wobei in der Übergabeposition der Saugrüssel mit dem Saugende einen der Klemmteller zugeordnet ist.The suction end of the suction nozzle can be positioned by the rotary drive between a rest position, a take-over position and a transfer position, wherein in the take-over position the suction nozzle is oriented transversely to the thread path of the incoming thread and in which Transfer position of the proboscis with the suction end is assigned to one of the clamping plates.

Die Übernahme des Fadens wird dabei insbesondere durch die Weiterbildung der Erfindung ermöglicht, bei welcher dem Saugende des Saugrüssels in der Übernahmeposition eine Schneideinrichtung zugeordnet ist, die zwischen einer Ruhestellung und einer Betriebsstellung höhenverstellbar ausgebildet ist. So kann die Schneideinrichtung bereits in der Übernahmeposition angeordnet sein, und nur bei Bedarf durch eine Höhenverstellung in den Fadenlauf geführt werden.The takeover of the thread is made possible in particular by the development of the invention, in which a cutting device is assigned to the suction end of the suction nozzle in the take-over position and is height-adjustable between a rest position and an operating position. The cutting device can thus already be arranged in the take-over position and can only be guided into the thread run by a height adjustment if necessary.

Die Schneideinrichtung wird bevorzugt durch einen Fadenführer und einen Messerhalter mit einer Schneide gebildet, die mit Abstand zueinander zwischen der Saugöffnung des Saugrüssels in der Übernahmeposition und dem Changierfadenführer angeordnet sind. Damit besteht die Möglichkeit, dass allein durch die Bewegung des Changierfadenführers der Faden in die Schneideinrichtung geführt wird. Der Fadenführer der Schneideinrichtung gewährleistet eine Positionierung des Fadens unmittelbar vor der Saugöffnung des Saugrüssels.The cutting device is preferably formed by a thread guide and a knife holder with a cutting edge, which are arranged at a distance from one another between the suction opening of the suction nozzle in the take-over position and the traversing thread guide. There is thus the possibility that the thread is guided into the cutting device solely by the movement of the traversing thread guide. The thread guide of the cutting device ensures that the thread is positioned directly in front of the suction opening of the suction nozzle.

Um in der Übernahmeposition den Faden allein durch die Bewegung des Saugrüssels übernehmen zu können, ist die Weiterbildung der Erfindung bevorzugt ausgeführt, bei welcher an dem Saugende des Saugrüssels eine Schneideinrichtung mit Abstand zu der Saugöffnung gehalten ist. So lässt sich die Schneideinrichtung durch die Bewegung des Saugrüssels in den Fadenlauf führen.In order to be able to take over the thread in the take-over position solely by the movement of the suction nozzle, the development of the invention is preferably carried out, in which a cutting device is held at a distance from the suction opening at the suction end of the suction nozzle. The cutting device can be guided into the thread run by the movement of the suction nozzle.

Damit der Faden selbsttätig erfasst und geschnitten werden kann, ist vorgesehen, dass die Schneideinrichtung eine zur Saugöffnung hervorragende Fadenleitkante und eine am Ende der Fadenleitkante V-förmige Messeranordnung aufweist, wobei eine Schneidkerbe der Messeranordnung gegenüber der Saugöffnung zurückversetzt ausgebildet ist. Damit ist gewährleistet, dass das Fadenende nach dem Durchtrennen des Fadens unmittelbar in die Saugöffnung am Saugende aufgenommen werden kann. Durch die hervorragende Fadenleitkante der Schneideinrichtung wird zudem ermöglich, dass selbst bei einem changierten Faden dieser mühelos in die Schneidkerbe gelangt.In order that the thread can be detected and cut automatically, it is provided that the cutting device has a thread guide edge which protrudes toward the suction opening and a V-shaped knife arrangement at the end of the thread guide edge, with a cutting notch of the knife arrangement being set back from the suction opening. This ensures that the thread end can be picked up immediately after cutting the thread in the suction opening at the suction end. The excellent thread guide edge of the cutting device also makes it possible for it to effortlessly get into the cutting notch, even if the thread changes.

Zur Unterstützung und Positionierung des Fadens ist die Weiterbildung der Erfindung besonders vorteilhaft, bei welcher der Saugrüssel am Saug-ende eine Halterung mit zumindest einem Führungsblech aufweist, welches eine Fadenführungskante zur Führung des Fadens bildet. So kann das Saugende des Saugrüssels unabhängig von der Saugöffnung zusätzliche Fadenführungsfunktionen übernehmen.To support and position the thread, the development of the invention is particularly advantageous, in which the suction nozzle at the suction end has a holder with at least one guide plate, which forms a thread guide edge for guiding the thread. So the suction end of the proboscis can take over additional thread guiding functions independent of the suction opening.

Derartige Führungsfunktionen können noch dadurch verbessert werden, indem die Halterung an dem Führungsblech einen Fadenführer trägt, der eine separate Fadenführungsnut zur Führung des Fadens aufweist.Such guide functions can be further improved by the holder on the guide plate carrying a thread guide which has a separate thread guide groove for guiding the thread.

Gemäß einer besonders vorteilhaften Ausbildung der Erfindung, ist der Fadenführer in einem Abstand zur Saugöffnung des Saugrüssels derart gehalten, dass die Saugöffnung des Saugrüssels und der Fadenführer einen geraden Fadenlauf aufspannen. Somit ist der Saugrüssel geeignet, um am Saugende einen Fadenabschnitt des zulaufenden Fadens zu führen.According to a particularly advantageous embodiment of the invention, the thread guide is held at a distance from the suction opening of the suction nozzle such that the suction opening of the suction nozzle and the thread guide span a straight thread run. The suction nozzle is therefore suitable for guiding a thread section of the incoming thread at the suction end.

Ein derartiger Fadenabschnitt ist somit besonders geeignet, um von einer rotierenden Fangeinrichtung erfasst zu werden. Insoweit ist die Weiterbildung der Erfindung besonders vorteilhaft, bei welcher der Längenabschnitt des Saugrüssels mit dem Saugende eine derartige Länge aufweist, dass in der Übernahmeposition des Saugendes ein zwischen der Saugöffnung und dem Fadenführer gespannter Fadenabschnitt einen Tellerrand des Klemmtellers umschlingt. Derartige Klemmteller weisen vorzugsweise am Tellerrand Fangnasen auf, die somit den Faden in einfacher Art und Weise vom Saugrüssel abgreifen können.Such a thread section is therefore particularly suitable for being gripped by a rotating catching device. In this respect, the development of the invention is particularly advantageous in which the length section of the suction nozzle with the suction end has such a length that in the takeover position of the suction end a thread section stretched between the suction opening and the thread guide wraps around a plate edge of the clamping plate. Clamping plates of this type preferably have catch tabs on the edge of the plate, which can thus easily pick up the thread from the proboscis.

Bei der Variante der Erfindung, bei welcher die Schneideinrichtung durch den Saugrüssel getragen wird, ist die Weiterbildung der Erfindung bevorzugt ausgeführt, bei welcher die Halterung an dem Saugende des Saugrüssels zu einer Seite der Saugöffnung die Schneideinrichtung und zu einer gegenüberliegenden Seite der Saugöffnung das Führungsblech mit dem Fadenführer trägt. Hierbei können vorteilhaft die Führungskante des Führungsbleches und die Fadenleitkante der Schneideinrichtung zusammenwirken, um beim Einschwenken des Saugrüssels den laufenden Faden zu erfassen.In the variant of the invention in which the cutting device is carried by the suction nozzle, the further development of the invention is preferably carried out in which the holder on the suction end of the suction nozzle has the cutting device on one side of the suction opening and the guide plate on an opposite side of the suction opening carries the thread guide. The guide edge of the guide plate and the thread guide edge of the cutting device can advantageously cooperate in order to detect the running thread when the suction nozzle swings in.

Um mit möglichst geringer Saugwirkung ein effektives Einsaugen des Fadens am Saugende des Saugrüssels zu ermöglichen, ist die Weiterbildung der Erfindung besonders vorteilhaft, bei welcher der Saugrüssel am Saugende eine Führungskerbe aufweist, die die Saugöffnung durchdringt. So lässt sich beispielsweise der Faden in der Übernahmeposition in die Führungskerbe am Saugende des Saugrüssels führen, so dass bereits die am Saugende eintretende Umgebungsluft auf den Faden einwirkt.In order to enable effective suction of the thread at the suction end of the suction nozzle with the lowest possible suction effect, the development of the invention is particularly advantageous in which the suction nozzle has a guide notch at the suction end which penetrates the suction opening. For example, the thread in the take-over position can be guided into the guide notch at the suction end of the suction nozzle, so that the ambient air entering at the suction end already acts on the thread.

Gemäß einer weiteren vorteilhaften Weiterbildung wird der Drehantrieb des Saugrüssels durch einen Schrittmotor gebildet, wobei der Längenabschnitt mit dem Saugende im Uhrzeigersinn und entgegen dem Uhrzeigersinn drehbar ist. So können alle Bewegungen des Saugrüssels schnell und präzise sowie mit hoher Wiederholbarkeit ausgeführt werden.According to a further advantageous development, the rotary drive of the suction nozzle is formed by a stepper motor, the length section being rotatable clockwise and counterclockwise with the suction end. In this way, all movements of the proboscis can be carried out quickly, precisely and with high repeatability.

Die erfindungsgemäße Vorrichtung zum Aufwickeln eines Fadens besitzt somit den besonderen Vorteil, dass die Spulenwechsel mit immer wiederkehrender Präzision ausführbar sind.The device according to the invention for winding a thread thus has the particular advantage that the bobbin changes can be carried out with recurring precision.

Im Nachfolgenden wird ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung zum Aufwickeln des Fadens unter Bezug auf die beigefügten Figuren näher erläutert.In the following an embodiment of the device according to the invention for winding the thread is explained in more detail with reference to the accompanying figures.

In den Fig. 1 und 2 ist ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung zum Aufwickeln eines Fadens schematisch in mehreren Ansichten dargestellt. In Fig. 1 ist das Ausführungsbeispiel in einer Seitenansicht und in Fig. 2 in einer Draufsicht gezeigt. Insoweit kein ausdrücklicher Bezug zu einer der Figuren gemacht ist, gilt die nachfolgende Beschreibung für beide Figuren.In the Fig. 1 and 2nd An embodiment of the device for winding a thread according to the invention is shown schematically in several views. In Fig. 1 is the embodiment in a side view and in Fig. 2 shown in a top view. Insofar as no express reference is made to one of the figures, the following description applies to both figures.

Das Ausführungsbeispiel der erfindungsgemäßen Vorrichtung zum Aufwickeln eines Fadens weist einen schwenkbaren Spulenhalter 1 auf, der an einer Schwenkachse 3 gelagert ist. Dem Spulenhalter 1 ist ein Schwenkantrieb 4 zugeordnet. An den freien Enden des gabelförmigen Spulenhalters 1 sind zwei sich gegenüberliegende Klemmteller 2.1 und 2.2 drehbar gelagert. Zwischen den Klemmtellern 2.1 und 2.2 ist eine Hülse 5 zur Aufnahme einer Spule gespannt. Hierzu weisen die Klemmteller 2.1 und 2.2 jeweils einen konischen Zentrieransatz auf, die teilweise in das Hülsenende hineinragen. Damit ist die Hülse 5 zwischen den Klemmtellern 2.1 und 2.2 zentriert.The embodiment of the device for winding a thread according to the invention has a pivotable bobbin holder 1 which is mounted on a pivot axis 3. A swivel drive 4 is assigned to the coil holder 1. At the free ends of the fork-shaped coil holder 1, two opposing clamping plates 2.1 and 2.2 are rotatably mounted. A sleeve 5 for receiving a coil is stretched between the clamping plates 2.1 and 2.2. For this purpose, the clamping plates 2.1 and 2.2 each have a conical centering projection which partially protrude into the sleeve end. The sleeve 5 is thus centered between the clamping plates 2.1 and 2.2.

An der Oberfläche der Hülse 5 bzw. an der Oberfläche einer gewickelten Spule 6 liegt eine Treibwalze 7 an. Die Treibwalze 7 ist mit einem hier nicht dargestellten Walzenantrieb gekoppelt, der die Treibwalze 7 mit im wesentlichen konstanter Geschwindigkeit zum Aufwickeln eines Fadens antreibt. Über Friktion wird die Hülse 5 zu einer Spulendrehzahl angetrieben, so dass ein Faden 28 auf der Hülse 5 zu einer Spule 6 aufgewickelt wird.A drive roller 7 rests on the surface of the sleeve 5 or on the surface of a wound coil 6. The drive roller 7 is coupled to a roller drive, not shown here, which the drive roller 7 with drives substantially constant speed for winding a thread. The sleeve 5 is driven to a spool speed via friction, so that a thread 28 is wound on the sleeve 5 to a spool 6.

Zum Aufwickeln des Fadens ist der Treibwalze 5 im Fadenlauf eine Changiereinrichtung 8 mit einem oszillierend angetriebenen Changierfadenführer 9 vorgeordnet. Der Changierfadenführer 9 wird durch einen Riemenantrieb 10 angetrieben. Hierbei ist es üblich, dass der Changierfadenführer 9 an einem Riemen befestigt ist, der über mehrere Umlenkrollen und eine Antriebsrolle geführt wird. Der Riemenantrieb 10 wird durch den Elektromotor 11 betrieben.In order to wind the thread, a traversing device 8 with an oscillatingly driven traversing thread guide 9 is arranged upstream of the drive roller 5 in the thread run. The traversing thread guide 9 is driven by a belt drive 10. It is common for the traversing thread guide 9 to be fastened to a belt which is guided over a plurality of deflection rollers and a drive roller. The belt drive 10 is operated by the electric motor 11.

Dem Changierfadenführer 9 ist im Fadenlauf ein Kopffadenführer 27 vorgeordnet, welcher den Zulauf des Fadens in die Aufwickelvorrichtung führt.The traversing thread guide 9 is preceded by a head thread guide 27 in the thread run, which guides the feed of the thread into the winding device.

In den Fig. 1 und 2 ist die normale Betriebssituation dargestellt, bei welcher der Faden 28 über den Kopffadenführer 27 zugeführt wird und kontinuierlich zur Spule 6 gewickelt wird. Dabei wird der Faden 28 durch den Changierfadenführer 9 oszillierend parallel zur Spulenoberfläche hin- und hergeführt, so dass sich eine Kreuzwicklung ergibt.In the Fig. 1 and 2nd the normal operating situation is shown in which the thread 28 is fed via the head thread guide 27 and is wound continuously to the bobbin 6. The thread 28 is oscillated back and forth by the traversing thread guide 9 parallel to the bobbin surface, so that a cross winding results.

Im Fadenlauf zwischen der Changiereinrichtung 8 und dem Kopffadenführer 27 ist eine Hilfseinrichtung 12 angeordnet, durch welche die Fadenführung während eines Spulenwechsels erfolgt. Die Hilfseirichtung 12 weist einen seitlich angeordneten Saugrüssel 13 auf, der ein bewegliches Sauende 14 mit einer Saugöffnung 20 aufweist. Innerhalb des Saugrüssels 13 ist ein Saugkanal 37 ausgebildet, der mit einer hier nicht dargestellten Absaugeinrichtung und einem Abfallbehälter verbunden ist. Der Saugrüssel 13 weist ein zum Saugende 14 gegenüberliegendes Anschlussende 17 auf, das drehbar gelagert ist und mit einem Drehantrieb 18 gekoppelt ist. Der Drehantrieb 18 weist einen Schrittmotor 19 auf, um an dem Saugende 14 des Saugrüssels 13 eine Schwenkbewegung zu initiieren.An auxiliary device 12 is arranged in the thread path between the traversing device 8 and the head thread guide 27, by means of which the thread is guided during a bobbin change. The auxiliary device 12 has a suction nozzle 13 arranged on the side, which has a movable sowing end 14 with a suction opening 20. A suction channel 37 is formed within the suction nozzle 13, which has a suction device, not shown here and a waste container is connected. The suction nozzle 13 has a connection end 17 opposite the suction end 14, which is rotatably mounted and is coupled to a rotary drive 18. The rotary drive 18 has a stepper motor 19 in order to initiate a pivoting movement at the suction end 14 of the suction nozzle 13.

Wie insbesondere aus der Darstellung in Fig. 1 hervorgeht, ist der Saugrüssel mit einer zwischen dem Saugende 14 und dem Anschlussende 17 ausgebildeten Krümmung 16 versehen. Insoweit weist der Saugrüssel 13 einen ersten Längsabschnitt 15.1 mit dem Saugende und einen zweiten Längsabschnitt 15.2 mit dem Anschlussende 17 auf. Der Längenabschnitt 15.1 ist hierbei wesentlich länger ausgeführt und lässt sich im Sinne eines Uhrzeigers im Uhrzeigersinn und entgegen dem Uhrzeigersinn bewegen.As shown in particular in Fig. 1 emerges, the suction nozzle is provided with a curvature 16 formed between the suction end 14 and the connection end 17. In this respect, the proboscis 13 has a first longitudinal section 15.1 with the suction end and a second longitudinal section 15.2 with the connection end 17. The length section 15.1 is made much longer and can be moved clockwise and counterclockwise.

Zur weiteren Erläuterung des Saugrüssels 13 wird zusätzlich zu den Fig. 3.1, 3.2 und 3.3 Bezug genommen. In den Fig. 3.1 bis 3.3 ist das Saugende 14 des Saugrüssels 13 in mehreren Ansichten dargestellt. In Fig. 3.1 ist eine Vorderansicht, in Fig. 3.2 eine Draufsicht und in Fig. 3.3 eine Seitenansicht gezeigt. Insoweit kein ausdrücklicher Bezug zu einer der Figuren gemacht ist, gilt die nachfolgende Beschreibung für beide Figuren.For further explanation of the proboscis 13 is in addition to the Fig. 3.1, 3.2 and 3.3 Referred. In the Fig. 3.1 to 3.3 the suction end 14 of the suction nozzle 13 is shown in several views. In Fig. 3.1 is a front view, in Fig. 3.2 a top view and in Fig. 3.3 a side view shown. Insofar as no express reference is made to one of the figures, the following description applies to both figures.

An dem Saugende 14 des Saugrüssels 13 ist eine Halterung 29 befestigt. Die Halterung 29 weist mit einem Abstand zur Saugöffnung 20 ein Führungsblech 30 auf. Das Führungsblech 30 trägt an einer Unterseite eine Führungskante 31, die zur Umlenkung des Fadens dient. An einer Seitenflanke des Führungsbleches 30 ist ein Fadenführer 32 eingelassen, der eine offene Führungsnut 33 aufweist. Der Fadenführer 32 ragt an dem Führungsblech 30 gegenüber dem Saugrüssel 13 hervor. Hierbei liegen der Fadenführer 32 und die Saugöffnung 20 im Wesentlichen in einer Fadenlaufebene.A holder 29 is fastened to the suction end 14 of the suction nozzle 13. The holder 29 has a guide plate 30 at a distance from the suction opening 20. The guide plate 30 has a guide edge 31 on an underside, which serves to deflect the thread. A thread guide 32, which has an open guide groove 33, is let in on a side flank of the guide plate 30. The thread guide 32 protrudes from the guide plate 30 opposite the suction nozzle 13. Here are the thread guides 32 and the suction opening 20 essentially in a thread running plane.

An dem Saugende 14 weist der Saugrüssel 13 eine durchgehende Fadenkerbe 34 auf, um einen Faden quer zur Saugöffnung 20 zu führen. Durch die Fadenkerbe 34 am Ende des Saugrüssels 13 lässt sich der Faden derart quer zur Saugöffnung 20 führen, dass bereits eine Saugwirkung am Faden wirksam wird. Die Fadenkerbe 34 am Saugende 14 wirkt mit der Führungskante 31 am Führungsblech 30, um in der Übernahmeposition ein Fadenende einsaugen zu können.At the suction end 14, the suction nozzle 13 has a continuous thread notch 34 in order to guide a thread transversely to the suction opening 20. The thread notch 34 at the end of the suction nozzle 13 allows the thread to be guided transversely to the suction opening 20 such that a suction effect on the thread is already effective. The thread notch 34 at the suction end 14 acts with the guide edge 31 on the guide plate 30 in order to be able to suck in a thread end in the takeover position.

Wie aus der Darstellung in Fig. 1 und 2 hervorgeht, enthält die Hilfseinrichtung 12 eine im mittleren Bereich angeordnete Schneideinrichtung 21. Die Schneideinrichtung 21 weist einen Messerhalter 22 mit einer Schneide 23 auf, welcher eine zur Changiermitte gerichtete Einlauföffnung aufweist. Dem Messerhalter 22 ist im Fadenlauf ein Fadenführer 24 vorgeordnet. Der Messerhalter 22 und der Fadenführer 24 sind gemeinsam an einem beweglichen Träger 25 gehalten, der über einen Hubantrieb 26 in seiner Höhe verstellbar ausgebildet ist.As shown in Fig. 1 and 2nd the auxiliary device 12 contains a cutting device 21 arranged in the central region. The cutting device 21 has a knife holder 22 with a cutting edge 23 which has an inlet opening directed towards the center of the traversing. A thread guide 24 is arranged upstream of the knife holder 22 in the thread path. The knife holder 22 and the thread guide 24 are held together on a movable support 25 which is adjustable in height by means of a lifting drive 26.

In der Fig. 1 und 2 ist die Hilfseinrichtung 12 jeweils außer Betrieb dargestellt. In diesem Fall befindet sich der Saugrüssel 13 in einer Ruheposition. In diesem Fall ist das Saugende 14 des Saugrüssels 13 entgegen der Fadenlaufrichtung seitlich neben dem Changierbereich gehalten.In the Fig. 1 and 2nd the auxiliary device 12 is shown out of operation. In this case, the suction nozzle 13 is in a rest position. In this case, the suction end 14 of the suction nozzle 13 is held laterally next to the traversing area counter to the thread running direction.

Die Schneideinrichtung 21 befindet sich ebenfalls in einer unteren Ruhestellung außerhalb des Fadenlaufs.The cutting device 21 is also in a lower rest position outside the thread path.

Für den Fall, dass eine Spule ihren gewünschten Durchmesser aufweist, wird ein Spulenwechsel eingeleitet. In Fig. 4.1 und 4.2 ist die Situation dargestellt, in welcher eine Fadenübernahme durch die Hilfseinrichtung bevorsteht. Fig. 4.1 zeigt eine Draufsicht und in Fig. 4.2 ist eine Seitenansicht der Betriebssituation zur Übernahme des Fadens gezeigt. Insoweit kein ausdrücklicher Bezug zu einer der Figuren gemacht ist, gilt die nachfolgende Beschreibung für beide Figuren.In the event that a coil has its desired diameter, a coil change is initiated. In Fig. 4.1 and 4.2 the situation is shown in which a thread takeover by the auxiliary device is imminent. Fig. 4.1 shows a plan view and in Fig. 4.2 a side view of the operating situation for taking over the thread is shown. Insofar as no express reference is made to one of the figures, the following description applies to both figures.

Zur Einleitung des Spulenwechsels wird zunächst der Drehantrieb 18 zum Verschwenken des Saugrüssels 13 aktiviert. Der Saugrüssel 13 wird aus der Ruheposition in eine Übernahmeposition geführt. Innerhalb der Übernahmeposition ist der Saugrüssel 13 im Wesentlichen quer zum Fadenlauf ausgerichtet, wobei die Führungskante 31 des Führungsbleches 30 am Saugende 14 über den Fadenlauf geführt ist. Anschließend wird die Schneideinrichtung 21 über den Hubantrieb 26 aus der Ruhestellung in die Betriebsstellung und damit in den Fadenlauf des Fadens 28 geführt. Der Faden wird hierbei von dem Fadenführer 24 erfasst und an der Führungskante 31 des Führungsbleches 30 derart umgelenkt, dass der Faden 28 quer zur Saugöffnung 20 am Saugende 14 verläuft. In dieser Situation wird der Faden durch den Changierfadenführer 9 geführt. Bei einer fortschreitenden Bewegung des Changierfadenführers 9 zu einem Hubende wird der Faden 28 in die Einlauföffnung des Messerhalters 22 geführt und durch die Schneide 23 durchtrennt. Das lose Fadenende wird sofort über die Saugöffnung 20 aufgenommen und über den Saugkanal 37 zu einem Abfallbehälter kontinuierlich geführt. Die Schneideinrichtung 21 wird durch den Hubantrieb 26 in der Ruhestellung zurückgeführt.To initiate the coil change, the rotary drive 18 for pivoting the suction nozzle 13 is first activated. The suction nozzle 13 is guided from the rest position into a takeover position. Within the take-over position, the suction nozzle 13 is aligned essentially transversely to the thread run, the guide edge 31 of the guide plate 30 being guided over the thread run at the suction end 14. The cutting device 21 is then guided via the lifting drive 26 from the rest position into the operating position and thus into the thread path of the thread 28. The thread is here gripped by the thread guide 24 and deflected at the leading edge 31 of the guide plate 30 such that the thread 28 runs transversely to the suction opening 20 at the suction end 14. In this situation, the thread is guided through the traversing thread guide 9. With a progressive movement of the traversing thread guide 9 to one end of the stroke, the thread 28 is guided into the inlet opening of the knife holder 22 and severed by the cutting edge 23. The loose end of the thread is immediately picked up via the suction opening 20 and continuously guided to a waste container via the suction channel 37. The cutting device 21 is returned by the lifting drive 26 in the rest position.

Nachdem die Spule an dem Spulenhalter durch eine neue Hülse ersetzt wurde, lässt sich der Aufwickelvorgang des Fadens fortsetzen. Zu diesem Zweck wird der Drehantrieb 18 der Hilfseinrichtung 12 erneut aktiviert. Hierbei wird zunächst der Saugrüssel 13 entgegen dem Uhrzeigersinn in Richtung der Ruheposition verschwenkt. Hierbei wird der Faden von der Führungskante 31 des Führungsbleches 30 abgestreift und verläuft unmittelbar in die Saugöffnung 20 des Saugrüssels 13. Sobald der Faden die Führungskante 31 des Führungsbleches 30 verlassen hat, wird die Drehbewegung des Drehantriebes 18 umgekehrt, so dass sich der Saugrüssel 13 im Uhrzeigersinn bewegt und in Richtung einer Übergabeposition geführt wird. Hierbei wird der Faden selbsttätig in den an der Seitenflanke des Führungsbleches 30 ausgebildeten Fadenführer 32 aufgenommen. Zwischen dem Fadenführer 32 und der Saugöffnung 20 wird nun ein Fadenabschnitt des Fadens 28 am Saugende 14 des Saugrüssels 13 geführt.After the bobbin on the bobbin holder has been replaced by a new sleeve, the winding process of the thread can be continued. For this purpose, the rotary drive 18 of the auxiliary device 12 is activated again. Here, the proboscis 13 is first pivoted counterclockwise in the direction of the rest position. Here, the thread is stripped from the guide edge 31 of the guide plate 30 and runs directly into the suction opening 20 of the suction nozzle 13. As soon as the thread has left the guide edge 31 of the guide plate 30, the rotary movement of the rotary drive 18 is reversed, so that the suction nozzle 13 in Moved clockwise and is guided in the direction of a transfer position. Here, the thread is automatically picked up in the thread guide 32 formed on the side flank of the guide plate 30. A thread section of the thread 28 is now guided at the suction end 14 of the suction nozzle 13 between the thread guide 32 and the suction opening 20.

Zur Erläuterung der Übergabe des Fadens wird nachfolgend zu der Figur 5 Bezug genommen. In Fig. 5 ist der Saugrüssel 13 in der Übergabeposition gehalten. In der Übergabeposition ist die Länge des Längenabschnittes 15.1 des Saugrüssels 13 bzw. die Position des Drehantriebes 18 derart gewählt, dass der sich zwischen dem Fadenführer 32 und der Saugöffnung 20 erstreckende Fadenabschnitt den Umfang des Klemmtellers 2.1 kontaktiert. Diese Situation ist in Fig. 5 dargestellt.To explain the handover of the thread is the following Figure 5 Referred. In Fig. 5 the proboscis 13 is held in the transfer position. In the transfer position, the length of the length section 15.1 of the suction nozzle 13 or the position of the rotary drive 18 is selected such that the thread section extending between the thread guide 32 and the suction opening 20 contacts the circumference of the clamping plate 2.1. This situation is in Fig. 5 shown.

An dem Klemmteller 2.1 ist am Umfang ein Einschnitt 36 mit einer Fangnase 35 ausgebildet. Bei fortschreitender Bewegung des Klemmtellers 2.1 fällt somit der Fadenabschnitt des Fadens 28 am Rand des Klemmtellers 2.1 in den Einschnitt 36 und wird somit durch die Fangnase 35 gefangen. Der Klemmteller 2.1 weist an einer Innenseite einen Klemm- und Schneidmechanismus auf, so dass der zulaufende Faden fixiert und an der Hülse 5 angewickelt werden kann. Hierbei lässt sich der Faden selbsttätig von dem Changierfadenführer 9 erfassen, so dass eine neue Spulenreise beginnt. Der Saugrüssel 13 wird in seine Ruheposition zurückversetzt, wobei der Saugrüssel 13 vorzugsweise entgegen dem Uhrzeitersinn verschenkt wird. Der Saugrüssel 13 lässt sich dabei über einen Schwenkwinkel von ca. 180° führen. Grundsätzlich sind die verschiedenen Positionen und Schwenkwinkel des Saugrüssels 13 beispielhaft. Im Extremfall wäre es auch möglich, dass der Saugrüssel 13 einen Schwenkwinkel von 360° durchlaufen könnte.An incision 36 with a catch 35 is formed on the circumference of the clamping plate 2.1. As the movement of the clamping plate 2.1 progresses, the thread section of the thread 28 at the edge of the clamping plate 2.1 falls into the incision 36 and is thus caught by the catch 35. The clamping plate 2.1 has a clamping and cutting mechanism on an inside on, so that the incoming thread can be fixed and wound on the sleeve 5. Here, the thread can be picked up automatically by the traversing thread guide 9, so that a new bobbin travel begins. The proboscis 13 is returned to its rest position, the proboscis 13 preferably being given away counter to the clock. The suction nozzle 13 can be guided over a swivel angle of approximately 180 °. Basically, the different positions and swivel angles of the proboscis 13 are exemplary. In an extreme case, it would also be possible for the suction nozzle 13 to pass through a swivel angle of 360 °.

An dieser Stelle sei noch darauf hingewiesen, dass die konstruktive Ausbildung der Hilfseinrichtung 12 insbesondere der mechanischen Einrichtungen zur Fadenführung teilweise beispielhaft sind. So lässt sich das Saug-ende 14 des Saugrüssels 13 auch ohne eine Halterung 29 ausführen, wobei zusätzliche Fadenführungselemente beispielsweise in der Übergabeposition oder in der Übernahmeposition angeordnet werden könnten. Ebenso ist die Ausbildung des Führungsbleches an der Halterung 29 beispielhaft. Wesentlich für die Erfindung ist die Beweglichkeit des Saugrüssels und die damit verbundene flexible Fadenführung während des gesamten Spulenwechsels.At this point it should also be pointed out that the design of the auxiliary device 12, in particular the mechanical devices for thread guidance, are in part exemplary. In this way, the suction end 14 of the suction nozzle 13 can also be designed without a holder 29, additional thread guide elements being able to be arranged, for example, in the transfer position or in the transfer position. The design of the guide plate on the holder 29 is also exemplary. The mobility of the suction nozzle and the associated flexible thread guidance during the entire bobbin change is essential for the invention.

In den Fig. 6.1, 6.2 und 6.3 ist so ein weiteres Ausführungsbeispiel der Hilfseinrichtung 12 gezeigt, wie es beispielsweise in der erfindungsgemäßen Vorrichtung zum Aufwickeln eines Fadens gemäß Fig. 1 und 2 eingesetzt werden könnte. Gegenüber dem Ausführungsbeispiel nach Fig. 1 und 2 ist bei diesem Ausführungsbeispiel der Hilfseinrichtung 12 eine Schneideinrichtung am Saugrüssel gehalten. Die Fig. 6.1 und 6.3 zeigen jeweils eine Seitenansicht und Fig. 6.2 eine Vorderansicht eines Saugendes eines Saugrüssels. Die nachfolgende Beschreibung gilt für alle Figuren, insoweit kein ausdrücklicher Bezug zu einer der Figuren gemacht ist.In the Fig. 6.1, 6.2 and 6.3 A further exemplary embodiment of the auxiliary device 12 is shown, as is the case, for example, in the device according to the invention for winding a thread Fig. 1 and 2nd could be used. Compared to the embodiment Fig. 1 and 2nd In this embodiment of the auxiliary device 12, a cutting device is held on the suction nozzle. The Fig. 6.1 and 6.3 each show a side view and Fig. 6.2 a front view of a suction end of a proboscis. The following description applies to all figures, insofar as no express reference is made to one of the figures.

Der Saugrüssel 13 ist identisch zu den vorgenannten Ausführungsbeispielen und weist einen ersten Längenabschnitt 15.1 mit einem Saugende 14 und einen zweiten Längsabschnitt 15.2 mit einem hier nicht dargestellten Anschlussende. Das Anschlussende ist drehbar gelagert und mit einem Drehantrieb gekoppelt, so dass sich der Längenabschnitt 15.1 mit dem Saugende 14 wie ein Uhrzeigersinn dreht.The suction nozzle 13 is identical to the aforementioned exemplary embodiments and has a first longitudinal section 15.1 with a suction end 14 and a second longitudinal section 15.2 with a connection end (not shown here). The connection end is rotatably mounted and coupled to a rotary drive, so that the length section 15.1 rotates clockwise with the suction end 14.

An dem Saugende 14 des Saugrüssels 13 ist eine Halterung 29 befestigt, die zu einer Seite einer Saugöffnung 20 eine Schneideinrichtung 38 und zur gegenüberliegenden Seite der Saugöffnung 20 ein Führungsblech 30 trägt. Die Schneideinrichtung 38 und das Führungsblech 30 sind in einem Abstand zu der Saugöffnung 20 gehalten.A holder 29 is attached to the suction end 14 of the suction nozzle 13 and carries a cutting device 38 to one side of a suction opening 20 and a guide plate 30 to the opposite side of the suction opening 20. The cutting device 38 and the guide plate 30 are held at a distance from the suction opening 20.

Wie aus der Darstellung in Fig. 6.1 und 6.2 hervorgeht, ist die Schneideinrichtung 38 auf der linken Seite der Saugöffnung 20 angeordnet. Hierbei befindet sich der Saugrüssel 13 in der in Fig. 6.2 gezeigten Situation in einer Ruhestellung. Die Schneideinrichtung 38 ist somit seitlich eines laufenden Fadens gehalten.As shown in Fig. 6.1 and 6.2 shows, the cutting device 38 is arranged on the left side of the suction opening 20. Here, the proboscis 13 is in the Fig. 6.2 shown situation in a rest position. The cutting device 38 is thus held to the side of a running thread.

Die Schneideinrichtung 38 weist in diesem Ausführungsbeispiel eine Fadenleitkante 39 auf, die mit einem freien Ende gegenüber der Saugöffnung 20 hervorragt. Die Fadenleitkante 39 mündet in eine Messeranordnung 40, die aus zwei V-förmig angeordneten Messern 40.1 und 40.2 gebildet ist. Insoweit mündet die Fadenleitkante 39 in eine Schneidkerbe 41 der Messeranordnung 40.In this exemplary embodiment, the cutting device 38 has a thread guide edge 39 which projects with a free end opposite the suction opening 20. The thread guide edge 39 opens into a knife arrangement 40 which is formed from two V-shaped knives 40.1 and 40.2. To this extent, the thread guide edge 39 opens into a cutting notch 41 of the knife arrangement 40.

Auf der gegenüberliegenden Seite der Saugöffnung 20 ist das Führungsblech 30 angeordnet, das eine gegenüber der Saugöffnung 20 hervorstehende Führungskante 31 mit einem freien Ende aufweist. Die Führungskante 31 mündet in eine Führungsnut 33, die einen Fadenführer 32 bildet, wie aus der Darstellung in Fig. 6.3 hervorgeht.On the opposite side of the suction opening 20, the guide plate 30 is arranged, which has a guide edge 31 protruding from the suction opening 20 with a free end. The guide edge 31 opens into a guide groove 33, which forms a thread guide 32, as shown in FIG Fig. 6.3 emerges.

Wie aus den Darstellungen in Fig. 6.1 bis 6.3 hervorgeht, ist an dem Saugende 14 des Saugrüssels 13 eine V-förmige Führungskerbe 34 ausgebildet, die die Saugöffnung 20 durchdringt. Die Führungskerbe 34 ist derart ausgerichtet, dass sich zwischen dem Fadenführer 32, der Führungskerbe 34 und der Schneidkerbe 41 eine Fadenlaufebene aufspannt.As from the representations in Fig. 6.1 to 6.3 a V-shaped guide notch 34 is formed on the suction end 14 of the suction nozzle 13 and penetrates the suction opening 20. The guide notch 34 is oriented in such a way that a thread running plane spans between the thread guide 32, the guide notch 34 and the cutting notch 41.

Um bei der in Fig. 1 und 2 dargestellten Aufwickelvorrichtung den Faden zum Zwecke eines Spulenwechsels zu übernehmen, wird der Saugrüssel 13 durch den Drehantriebe in eine Übernahmeposition verschenkt. In dieser Situation wird der Faden über die Führungskante 31 des Führungsbleches 30 sowie über die Fadenleitkante 39 der Schneideinrichtung 38 erfasst und zur Saugöffnung 20 des Saugrüssels 13 geleitet. Bei fortschreitender Bewegung gelangt der Faden in die Messeranordnung 40 der Schneideinrichtung 38 und wird in der Schneidkerbe 41 durchtrennt. Das sich bildende lose Fadenende wird unmittelbar in der Saugöffnung 20 eingesogen und gemeinsam mit dem Fadenführer 32 geführt.To at the in Fig. 1 and 2nd shown take-up device to take over the thread for the purpose of changing the bobbin, the suction nozzle 13 is given away by the rotary drives in a takeover position. In this situation, the thread is grasped via the guide edge 31 of the guide plate 30 and via the thread guide edge 39 of the cutting device 38 and passed to the suction opening 20 of the suction nozzle 13. As the movement progresses, the thread enters the knife arrangement 40 of the cutting device 38 and is cut in the cutting notch 41. The loose thread end that is formed is sucked directly into the suction opening 20 and guided together with the thread guide 32.

Sobald die Vollspule von dem Spulenhalter abgenommen und durch eine neue Leerhülse ersetzt ist, kann der neue Wickelvorgang beginnen. Hierzu wird nun der Saugrüssel 13 mit dem Saugende 14 in die Übergabeposition geführt. Diese Situation ist identisch zu dem zuvor beschriebenen Ausführungsbeispiel nach Fig. 5. Insoweit wird an dieser Stelle Bezug zu der Fig. 5 genommen.As soon as the full bobbin is removed from the bobbin holder and replaced by a new empty tube, the new winding process can begin. For this purpose, the suction nozzle 13 is now guided into the transfer position with the suction end 14. This situation is identical to the previously described embodiment to Fig. 5 . In this respect, reference is made to the Fig. 5 taken.

Sobald der Faden übernommen und durchtrennt ist, wird der Saugrüssel 13 durch den Drehantrieb zurück in seine Ruheposition versetzt.As soon as the thread has been taken over and severed, the suction nozzle 13 is returned to its rest position by the rotary drive.

Das in Fig. 6.1 bis 6.3 beschriebene Ausführungsbeispiel der Hilfseinrichtung 12 stellen somit eine weitere konstruktive Ausführungsvariante dar, die zur Automatisierung eines Spulenwechsels in einer Aufwickelvorrichtung geeignet ist. Durch die Positioniersicherheit des Saugrüssels durch den als Schrittmotor ausgebildeten Drehantrieb werden sehr hohe Fang- und Übergabesicherheiten zur Führung des Fadens erreicht.This in Fig. 6.1 to 6.3 The exemplary embodiment of the auxiliary device 12 described thus represents a further design variant which is suitable for automating a bobbin change in a winding device. Due to the positioning security of the suction nozzle due to the rotary drive designed as a stepper motor, very high safety catches and handovers for guiding the thread are achieved.
