Abstract

Disclosed are a method and a device for continuously winding up several threads to bobbins (5). According to the invention, the bobbins (5) are simultaneously retained and wound on two driven bobbin spindles (7.1, 7.2). Each of said bobbin spindles (7.1, 7.2) is disposed on two rotatably mounted bobbin revolvers (10.1, 10.2) which are provided with two additional driven bobbin spindles (11.1, 11.2) for taking over the threads and continuing the winding process. During the winding process, the threads are fed to the bobbins (5) by means of two pressing rollers (6.1, 6.2) which are allocated to the bobbin spindles and rest against the circumference of the bobbins (5). In order to ensure that all threads are pulled as uniformly as possible off a device that is mounted upstream when changing bobbins on both bobbin spindles (11.1, 11.2), the pressing rollers (6.1, 6.2) are driven at a thread-guiding circumferential speed which is greater than the circumferential speed of the bobbins (5) of both bobbin spindles (11.1, 11.2) when changing the bobbin spindle. To this avail, both pressing rollers (6.1, 6.2) are driven by a joint roller drive unit which is connected to a control device (21) that controls the rotary drive of the bobbin revolvers (10.1, 10.2).

Description

Die Erfindung betrifft ein Verfahren zum kontinuierlichen Aufwickeln mehrerer Fäden zu Spulen gemäß dem Oberbegriff des Anspruchs 1, sowie eine Vorrichtung zur Durchführung des Verfahrens gemäß dem Oberbegriff des Anspruchs 7.The invention relates to a method for continuously winding a plurality of threads into coils according to the preamble of claim 1, and to an apparatus for carrying out the method according to the preamble of claim 7.

Ein gattungsgemäßes Verfahren und eine gattungsgemäße Vorrichtung sind aus der WO 03/068648 A1 bekannt.A generic method and a generic device are from the WO 03/068648 A1 known.

Bei dem bekannten Verfahren und der bekannten Vorrichtung werden die Fäden gleichzeitig in zwei nebeneinander angeordneten Spulspindeln zu Spulen aufgewickelt. Hierzu sind die Spulspindeln durch jeweils einen Spindelantrieb angetrieben. Jeder der Spulspindeln ist einer Andrückwalze zugeordnet, die über eine Schwinge radial beweglich zur Spulspindel gehalten ist. Während des Aufwickelns der Fäden zu Spulen, liegen die frei drehbaren Andrückwalzen am Umfang der Spulen an. Beide Spulspindeln sind auskragend an jeweils einem Spulrevolver angeordnet. Die Spulrevolver tragen jeweils eine zweite um 180° versetzt angeordnete Spulspindel. Durch Drehung der Spulrevolver können somit abwechselnd die Spulen an beiden dem Spulrevolver zugeordneten Spulspindeln gewickelt werden. Zum Spulenwechsel wird die jeweils in Betriebsstellung befindliche Spulspindel mit den Vollspulen durch Drehbewegung der Spulrevolver von den zugeordneten Andrückwalzen wegbewegt. Gleichzeitig gelangt die jeweilig zweite Spulspindel zur Übernahme der Fäden in Kontakt mit den Andrückwalzen.In the known method and the known device, the threads are simultaneously wound in two juxtaposed winding spindles into coils. For this purpose, the winding spindles are driven by a respective spindle drive. Each of the winding spindles is associated with a pressure roller, which is held by a rocker radially movable to the winding spindle. During the winding of the threads into coils, the freely rotatable pressure rollers abut the circumference of the coils. Both winding spindles are arranged cantilevered on each one Spulrevolver. The winding turrets each carry a second winding spindle arranged offset by 180 °. By rotating the spool turrets, the spools can thus be alternately wound on both spool spindles associated with the spool turret. To change bobbins, the winding spindle, which is in each case in the operating position, is moved away from the associated pressure rollers with the full bobbins by rotary movement of the bobbin turrets. At the same time the respective second winding spindle comes to take over the threads in contact with the pressure rollers.

Bei dem bekannten Verfahren und der bekannten Vorrichtung besteht der Nachteil, dass aufgrund von Toleranzen im Aufbau der Vorrichtung sowie aufgrund von Titerschwankungen des Fadens an beiden Spulspindeln Spulen mit unterschiedlichem Durchmesser gewickelt werden können. Insbesondere in der Phase eines Spulenwechsels, bei welchem die Spulspindeln mit den Vollspulen ohne Kontakt zu den Andrückwalzen den Abzug der Fäden ausführen, sind Fadenspannungsschwankungen, die insbesondere bei vollverstreckten Fäden bis zum Verschlappen der Fäden führen können, unvermeidlich.In the known method and the known device has the disadvantage that due to tolerances in the structure of the device as well as due to titer variations of the thread on both winding spindles coils with different diameters can be wound. In particular, in the phase of a bobbin change, in which the winding spindles with the full bobbins without contact with the pressure rollers perform the withdrawal of the threads, are thread tension fluctuations, which can lead to slipping of the threads especially in fully drawn threads, inevitable.

Aus der WO03/068648 A ist eine automatische Gamwickelmaschine des Drehtyps mit mindestens zwei jeweils um eine Achse drehbaren Drehkopftischen bekannt, von denen jeder wenigstens zwei drehbar darauf befestigte Spulenhalter trägt.From the WO03 / 068648 A there is known an automatic yarn winding machine of the rotary type having at least two rotary head tables each rotatable about an axis, each of which carries at least two spool holders rotatably mounted thereon.

Ferner ist aus der EP 0 391 101 A1 ein Spulenwechselverfahren mit Domantrieb bekannt. Dabei wird beim verlustlosen Spulenwechsel in einem Spuler mit einer Kontaktwalze und Domantrieb die Drehzahl der Kontaktwalze während des Spulenwechsels gegenüber dem Spulbetrieb erhöht.Furthermore, from the EP 0 391 101 A1 a bobbin change method with Domantrieb known. In this case, the speed of the contact roller during the bobbin change compared to the winding operation is increased in the lossless bobbin change in a winder with a contact roller and Domantrieb.

Demgemäß ist es Aufgabe der Erfindung, ein Verfahren und eine Vorrichtung der eingangs genannten Art so weiterzubilden, dass ein gleichmäßiger Abzug der Fäden ohne wesentliche Fadenspannungsschwankungen während eines Spulwechsels an allen gleichzeitig gewickelten Fäden erhalten bleibt.Accordingly, it is an object of the invention to develop a method and an apparatus of the type mentioned so that a uniform withdrawal of the threads without significant thread tension fluctuations during a Spulwechsels is maintained at all simultaneously wound threads.

Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den Merkmalen nach Anspruch 1 und durch eine Vorrichtung mit den Merkmalen nach Anspruch 7 gelöst.This object is achieved by a method with the features of claim 1 and by a device having the features of claim 7.

Vorteilhafte Weiterbildungen der Erfindung sind durch die Merkmale und Merkmalskombinationen der jeweiligen Unteransprüche definiert.Advantageous developments of the invention are defined by the features and feature combinations of the respective subclaims.

Die Erfindung war auch nicht dadurch nahegelegt, dass grundsätzlich Aufspulmaschinen bekannt sind, die mehrere Fäden an einer Spulspindel zu Spulen wickeln, wie beispielsweise aus der EP 0 391 101 A1 bekannt. Hierbei wird die Spulspindel durch einen Spindelantrieb und die Andrückwalze durch einen Walzenantrieb angetrieben. In den Phasen eines Spulenwechsels wird die Umfangsgeschwindigkeit der Andrückwalze erhöht, um die Fadenspannung im Fadenlauf oberhalb der Andrückwalze auf einem bestimmten Niveau zu halten. Damit wird zwar vorteilhaft die Fadenzuführung zu einer Spulspindel beeinflusst. Die Problematik der gleichzeitigen Zuführung mehrerer Fäden zu zwei Spulspindeln bleibt hierbei jedoch völlig unberücksichtigt.The invention was not suggested by the fact that in principle winding machines are known which wind several threads on a winding spindle to coils, such as from EP 0 391 101 A1 known. Here, the winding spindle is driven by a spindle drive and the pressure roller by a roller drive. In the phases of a bobbin change, the peripheral speed of the pressure roller is increased in order to keep the yarn tension in the yarn path above the pressure roller at a certain level. This will be beneficial influences the thread feed to a winding spindle. The problem of the simultaneous feeding of several threads to two winding spindles remains completely unconsidered.

Die Erfindung besitzt den besonderen Vorteil, dass trotz möglicher unterschiedlicher Wickeldurchmesser die Zuführung der Fäden an beiden Spulspindeln maßgeblich durch die zwischen den Fäden und den Andrückwalzen eingestellten Umschlingungsverhältnisse bestimmt sind. Hierzu werden beide Andrückwalzen während des Wechsels der Spulspindel mit einer überhöhten Umfangsgeschwindigkeit zurThe invention has the particular advantage that despite possible different winding diameters, the feeding of the yarns on both winding spindles are largely determined by the looping ratios set between the yarns and the pressure rollers. For this purpose, both pressure rollers during the change of the winding spindle with an excessive peripheral speed for

Führung der Fäden angetrieben, die größer ist als jede der Spulumfangsgeschwindigkeiten der Spulen beider Spulspindeln. Die erfindungsgemäße Vorrichtung weist hierzu einen Walzenantrieb für beide Andrückwalzen auf, wobei der Walzenantrieb mit einer den Drehantrieb der Spulrevolver zugeordneten Steuereinrichtung verbunden ist. Damit ist sichergestellt, dass die Veränderungen der Umfangsgeschwindigkeiten der Andrückwalze in Abhängigkeit von der Drehbewegung des Spulrevolvers ausführbar ist.Guiding the filaments driven, which is greater than each of the Spulumfangsgeschwindigkeiten the coils of both winding spindles. For this purpose, the device according to the invention has a roller drive for both pressure rollers, wherein the roller drive is connected to a control device associated with the rotary drive of the spindle turret. This ensures that the changes in the peripheral speeds of the pressure roller in dependence on the rotational movement of the winding turret is executable.

Die Erhöhung der Umfangsgeschwindigkeit an den Andrückwalzen erfolgt durch synchrone Beschleunigung beider Andrückwalzen. Hierzu kann der Walzenantrieb durch jeweils einen Elektromotor mit einem Getriebemittel, welches beide Andrückwalzen miteinander verbindet, oder durch jeweils zwei separate Elektromotoren, die durch ein gemeinsames Steuergerät angesteuert werden, gebildet sein.The increase of the peripheral speed at the pressure rollers is effected by synchronous acceleration of both pressure rollers. For this purpose, the roller drive can be formed in each case by an electric motor with a gear means, which connects both pressure rollers with each other, or by two separate electric motors, which are controlled by a common control device.

Um möglichst beide im Betrieb befindlichen Spulspindeln mit identischen Drehzahlen und damit identischen Umfangsgeschwindigkeiten der Spulen betreiben zu können, wird jede der Spulspindeln synchron angetrieben und gesteuert.In order to be able to operate as possible both spool spindles in operation with identical speeds and thus identical peripheral speeds of the coils, each of the winding spindles is synchronously driven and controlled.

Die erfindungsgemäße Verfahrensvariante, bei welcher die Andrückwalzen während des Wickelns der Spulen derart angetrieben bleiben, dass eine Schlupfeinstellung zwischen den Spulen und den Andrückwalzen möglich ist, bietet den besonderen Vorteil, dass die während der Spulreise auftretenden Unterschiede im Anwachsen der Spulendurchmesser vorteilhaft kompensiert werden können. So lassen sich die Andrückwalzen gegenüber den Spulen sowohl treibend als auch bremsend antreiben. Vorzugsweise begünstigt eine leichte Überhöhung der Andrückwalzendrehzahl das Aufwickeln der Fäden.The method variant according to the invention, in which the pressure rollers during the winding of the coils remain driven in such a way that a slip adjustment is possible between the coils and the pressure rollers, offers the particular advantage that the differences occurring during the winding cycle in the increase of the coil diameter can be compensated advantageous. Thus, the pressure rollers can drive both the driving and braking against the coils. Preferably, a slight exaggeration of the Andrückwalzendrehzahl favors the winding of the threads.

Eine weitere Stellmöglichkeit zur Beeinflussung des Spulenaufbaus ist durch die Verfahrensvariante gemäß der erfindungsgemäßen Weiterbildung nach Anspruch 3 und 4 gegeben. Hierzu sind die Andrückwalze bevorzugt starr mit einem höhenverstellbaren Halter verbunden, so dass an jeder Spulspindel im wesentlichen gleiche gemischte Zuordnungen gehalten werden können. Zudem lässt sich eine für das Aufwickeln der Spulen an beiden Spulspindeln die von den Andrückwalzen aufzubringende Anlagekraft mit einfachen Mitteln einstellen.Another possibility for influencing the coil structure is given by the process variant according to the invention according to claim 3 and 4. For this purpose, the pressure roller are preferably rigidly connected to a height-adjustable holder, so that substantially identical mixed assignments can be maintained on each winding spindle. In addition, one can set for the winding of the coils on both winding spindles applied by the pressure rollers contact force with simple means.

Es ist jedoch grundsätzlich auch möglich, die Andrückwalzen über bewegliche Mittel mit dem Halter zu verbinden.However, it is in principle also possible to connect the pressure rollers via movable means with the holder.

Die während des Aufspulens der Fäden an beiden im Betrieb befindlichen Spulspindeln erforderliche Ausweichbewegung zum Anwachsen der Spulen, lässt sowohl durch wegführen der Andrückwalzen mittels des beweglichen Halters oder durch Drehbewegung vorzugsweise synchrone Drehbewegung der beiden Spulrevolver ausführen. Zur Bewegung des Halters wird insbesondere ein Schlitten und eine Schlittenführung vorgeschlagen, durch welchen beide Andrückwalzen synchron bewegt werden können.The evasive movement required for winding the bobbins during winding of the threads on both winding spindles in operation can be carried out both by moving the pressure rollers away by means of the movable holder or by rotational movement, preferably synchronous rotational movement of the two winding turrets. To move the holder, in particular a carriage and a slide guide is proposed, by which both pressure rollers can be moved synchronously.

Alternativ besteht jedoch auch die Möglichkeit, die Andrückwalzen jeweils an zwei beweglichen Schwingen zu halten, die unmittelbar schwenkbar an dem Maschinengestell befestigt sind. Diese Weiterbildung ist im besonderen für die Verfahrensvariante geeignet, bei welcher die Ausweichbewegung ausschließlich durch Drehung der beiden Spulrevolver ausgeführt wird.Alternatively, however, it is also possible to hold the pressure rollers each on two movable rockers, which are directly pivotally mounted on the machine frame. This development is particularly suitable for the process variant in which the evasive movement is performed exclusively by rotation of the two winding turret.

Damit während des Aufwickelns der Fäden am beiden Spulspindeln ein möglichst konstanter Abzug der Fäden und Zuführung der Fäden gewährleistet ist, erfolgt die Regelung der Spindelantriebe zur Einstellung der Spulenumfangsgeschwindigkeit bevorzugt synchron. Hierzu wird vorzugsweise die Drehgeschwindigkeit einer der Andrückwalzen erfasst und als Regelgröße zur Einstellung der Spulumfangsgeschwindigkeiten verwendet. Diese Weiterbildung der Erfindung zeichnet sich besonders dadurch aus, dass die Veränderung der Antriebsdrehzahlen der Spulspindeln während des Aufwickelns der Spulen durch einen gemeinsamen Regelkreis gesteuert werden können. Mittels einer Steuereinrichtung wird in Abhängigkeit von der jeweilig gemessenen Drehgeschwindigkeit der Andrückwalze eine kollektive Änderung der Antriebsdrehzahlen der Spulspindeln derart durchgeführt, dass die Drehgeschwindigkeit der detektierten Andrückwalze im wesentlichen konstant bleibt. Dabei wird automatisch die zweite nicht im Regelkreis eingebundene Andrückwalze in den gleichen Zustand versetzt, wie die durch einen Sensor überwachte Andrückwalze. Die Weiterbildung der erfindungsgemäßen Vorrichtung weist zur Durchführung dieser Verfahrensvariante einen Drehzahlsensor auf, der einer der Andrückwalzen zugeordnet ist, um deren Drehgeschwindigkeiten zu erfassen. Der Drehzahlsensor ist mit den Spindelantrieben der in Betriebsstellung befindlichen Spulspindeln durch eine Steuereinrichtung zu einem Regelkreis verbunden. Das Sensorsignal kann somit vorteilhaft zur Ansteuerung beider Spindelantriebe genutzt werden.In order to ensure the most constant possible withdrawal of the threads and feeding of the threads during the winding of the threads on the two winding spindles, the control of the spindle drives for setting the circumferential speed of the coil is preferably synchronous. For this purpose, the rotational speed of one of the pressure rollers is preferably detected and used as a controlled variable for setting the Spulumfangsgeschwindigkeiten. This development of the invention is characterized in particular by the fact that the change in the drive speeds of the winding spindles during the winding of the coils by a common Control circuit can be controlled. By means of a control device, a collective change of the drive speeds of the winding spindles is carried out in such a manner depending on the respective measured rotational speed of the pressure roller, that the rotational speed of the detected pressure roller remains substantially constant. In this case, the second non-integrated in the control loop pressure roller is automatically placed in the same state as the monitored by a sensor pressure roller. The development of the device according to the invention has for carrying out this process variant on a speed sensor which is assigned to one of the pressure rollers to detect their rotational speeds. The speed sensor is connected to the spindle drives of the winding spindles in the operating position by a control device to a control loop. The sensor signal can thus be used advantageously for controlling both spindle drives.

In den Fig. 1 bis 4 ist ein erstes Ausführungsbeispiel der erfindungsgemäßen Aufspulvorrichtung in mehreren Ansichten dargestellt. Hierbei zeigt die Fig. 1 eine Seitenansicht des Ausführungsbeispiels, Fig. 2 eine Draufsicht der Spulspindeln des Ausführungsbeispiels sowie Fig. 3 und 4 eine Vorderansicht des Ausführungsbeispiels in verschiedenen Betriebssituationen. Insoweit kein Bezug zu einer der Figuren gemacht ist, gilt die nachfolgende Beschreibung für alle Figuren.In the Fig. 1 to 4 a first embodiment of the winding device according to the invention is shown in several views. This shows the Fig. 1 a side view of the embodiment, Fig. 2 a plan view of the winding spindles of the embodiment and Fig. 3 and 4 a front view of the embodiment in different operating situations. Inasmuch as no reference is made to one of the figures, the following description applies to all figures.

Das Ausführungsbeispiel der erfindungsgemäßen Aufspulvorrichtung weist zwei Spulstellten 29.1 und 29.2 auf, die die nebeneinander in einem Maschinengestell 12 ausgebildet sind. Hierbei sind die Spulstellen 29.1 und 29.2 spiegelbildlich zu einer mittleren Symmetrieebene angeordnet. So besteht die rechte Spulstelle 29.1 aus einem drehbar in dem Maschinengestell 21 gelagerten Spulrevolver 10.1. An dem Spulrevolver 10.1 sind eine erste auskragende Spulspindel 7.1 und 180° versetzt eine zweite auskragende Spulspindel 11.1 gehalten. In der dargestellten Betriebssituation befindet sich die erste Spulspindel 7.1 in einer Betriebsstellung zum Aufwickeln mehrerer Fäden. Die zweite Spulspindel 11.1 befindet sich in einer Wechselstellung zum Austausch von Vollspulen gegen leere Spulhülsen.The embodiment of the winding device according to the invention has two winding points 29.1 and 29.2, which are formed side by side in a machine frame 12. Here, the winding units 29.1 and 29.2 are arranged in mirror image to a central plane of symmetry. Thus, the right winding unit 29.1 consists of a rotatably mounted in the machine frame 21 Spulrevolver 10.1. At the Spulrevolver 10.1 a first cantilevered winding spindle 7.1 and 180 ° offset a second cantilevered winding spindle 11.1 held. In the illustrated operating situation, the first winding spindle 7.1 is in an operating position for winding a plurality of threads. The second winding spindle 11.1 is in a change position for replacing full bobbins with empty bobbins.

Spiegelbildlich zu ersten Spulrevolver 10.1 ist in der zweiten Spulstelle 29.2 ein zweiter in gleicher horizontalen Ebene angeordneter Spulrevolver 10.2 in dem Maschinengestell 12 gehalten. Der Spulrevolver 10.2 trägt die auskragenden Spulspindeln 7.2 und 11.2. In der dargestellten Betriebssituation befindet sich die Spulspindel 7.2 in der Betriebsstellung und die Spulspindel 11.2 in einer Wechselstellung.Mirrored to first Spulrevolver 10.1 a second arranged in the same horizontal plane Spulrevolver 10.2 is held in the machine frame 12 in the second winding unit 29.2. The winding turret 10.2 carries the projecting winding spindles 7.2 and 11.2. In the illustrated operating situation, the winding spindle 7.2 is in the operating position and the winding spindle 11.2 in a change position.

Beide Spulrevolver 10.1 und 10.2 sind mit einem gemeinsamen Drehantrieb 30 gekoppelt, wobei die Spulrevolver 10.1 und 10.2 mit gegensinnigem Drehsinn antreibbar sind. Der Drehantrieb 30 ist mit einer zentralen Steuereinrichtung 21 verbunden. Jeder der an den Spulrevolvern 10.1 und 10.2 gehaltenen Spulspindeln 7.1, 7.2, 11.1 und 11.2 ist jeweils ein Spindelantrieb zugeordnet. In Fig. 1 sind die Spindelantriebe 23.2 und 31.2 der Spulspindel 7.2 und 11.2 der Spulstelle 29.2 gezeigt. Die Spindelantriebe 23.1, 23.2, 31.1 und 31.2 der Spulspindel beider Spulstellen 29.1 und 29.2 sind mit der zentralen Steuereinrichtung 21 verbunden, wie aus Fig. 2 hervorgeht.Both Spulrevolver 10.1 and 10.2 are coupled to a common rotary drive 30, wherein the Spulrevolver 10.1 and 10.2 are driven with opposite directions of rotation. The rotary drive 30 is connected to a central control device 21. Each of the winding spindles 7.1, 7.2, 11.1 and 11.2 held on the winding turrets 10.1 and 10.2 is assigned a respective spindle drive. In Fig. 1 are the spindle drives 23.2 and 31.2 of the winding spindle 7.2 and 11.2 of the winding unit 29.2 shown. The spindle drives 23.1, 23.2, 31.1 and 31.2 of the winding spindle of both winding units 29.1 and 29.2 are connected to the central control device 21, as shown Fig. 2 evident.

Jedem der Spulrevolver 10.1 und 10.2 ist im Fadenlauf jeweils eine Andrückwalze 6.1 und 6.2 vorgeordnet. In der Spulstelle 29.1 wirken dabei die Andrückwalzen 6.1 mit den Spulspindeln 7.1 zusammen, um mehrere Fäden 1.1 zu jeweils einer Spule zu wickeln. Während des Aufwickelns der Fäden 1.1 legt die Andrückwalze 6.1 am Umfang der zu wickelnden Spulen 9 an.Each of the Spulrevolver 10.1 and 10.2 is preceded by a pressure roller 6.1 and 6.2 in the yarn path. In the winding unit 29.1, the pressure rollers 6.1 cooperate with the winding spindles 7.1 in order to wind a plurality of yarns 1.1 to a respective spool. During the winding of the threads 1.1, the pressure roller 6.1 engages the circumference of the coils 9 to be wound.

In der Spule 29.2 wirkt dementsprechend die Andrückwalze 6.2 mit der in der Betriebsstellung befindlichen Spulspindel in diesem Fall 7.2 zusammen, um eine zweite Fadenschar von Fäden 1.2 zu Spulen zu wickeln. Auch hierbei liegt die Andrückwalze 6.2 am Umfang der zu wickelnden Spulen 9 an.Accordingly, in the coil 29.2, the pressure roller 6.2 cooperates with the winding spindle located in the operating position in this case 7.2 in order to wind a second group of threads of threads 1.2 into coils. Here, too, the pressure roller 6.2 abuts the circumference of the coils 9 to be wound.

Die Andrückwalzen 6.1 und 6.2 sind drehbar an einem Halter 13 gelagert und durch den Halter 13 starr miteinander verbunden. Hierbei ist den Andrückwalzen 6.1 und 6.2 ein Walzenantrieb 17 zugeordnet, wie in Fig. 1 dargestellt.The pressure rollers 6.1 and 6.2 are rotatably mounted on a holder 13 and rigidly connected to each other by the holder 13. Here, the pressure rollers 6.1 and 6.2, a roller drive 17 is assigned, as in Fig. 1 shown.

Der Halter 13 trägt ein den Andrückwalzen 6.1 und 6.2 vorgeordnetes Changiermittel 4. Das Changiermittel 4 ist in einer Mittelebene der Fadenzuführung zwischen den Spulstellen 29.1 und 29.2 angeordnet und weist zu jeder Spulstelle 29.1 und 29.2 mehrere Changierfadenführer 5.1 und 5.2 auf, durch welche die zulaufenden Fäden 1.1 und 1.2 innerhalb eines Changierhubes hin- und herverlegt werden. Das Changiermittel 4 läßt sich beispielsweise durch eine Kehrgewindewelle ausbilden, die am Umfang ein oder mehrere Nuten zur Führung der Changierfadenführer 5.1 und 5.2 aufweist.The holder 13 carries the pressure rollers 6.1 and 6.2 upstream of traversing 4. The traversing means 4 is arranged in a median plane of the yarn feed between the winding units 29.1 and 29.2 and has to each winding unit 29.1 and 29.2 several traversing yarn guides 5.1 and 5.2, through which the tapered yarns 1.1 and 1.2 are moved back and forth within a traverse stroke. The traversing means 4 can be formed for example by a Kehrgewindewelle having one or more grooves on the circumference for guiding the traversing yarn guides 5.1 and 5.2.

Auf einer Oberseite des Halters 13 ist ein Fadenführerträger 3 vorgesehen, welcher zwei Gruppen von Kopffadenführern 2.1 und 2.2 trägt. Die Kopffadenführer 2.1 und 2.2 bilden die Fadenzuführung zwischen den Spulspindeln 7.1 und 7.2.On an upper side of the holder 13, a yarn guide carrier 3 is provided, which carries two groups of head thread guides 2.1 and 2.2. The head thread guides 2.1 and 2.2 form the thread feed between the winding spindles 7.1 and 7.2.

Hierbei ist die Gruppe der Fadenführer 2.1 der Spulstelle 29.1 zugeordnet und die Gruppe der Fadenführer 2.2 der Spulstelle 29.2 zugeordnet.Here, the group of yarn guide 2.1 of the winding unit is assigned 29.1 and assigned the group of yarn guide 2.2 of the winding unit 29.2.

Der Halter 13 ist durch einen Schlitten 15 und die Schlittenführung 14.1 und 14.2 vertikal beweglich an dem Maschinengestell 12 gehalten. Der Schlitten 15 wird dabei durch einen Kraftgeber 32 in der Schlittenführung 14.1 und 14.2 derart gehalten, dass die Andrückwalzen 6.1 und 6.2 mit jeweils einer vorbestimmten Anlagekraft während des Aufwickelns der Fäden 1.1 und 1.2 an den jeweiligen Spulen 9 anliegen. Der Kraftgeber 32 ist in diesem Ausführungsbeispiel durch zwei Entlastungszylindereinheiten 16.1 und 16.2 ausgebildet, durch welche das Gesamtgewicht der beiden Andrückwalzen 6.1 und 6.2 sowie des Halters 13 und den zusätzlich an dem Halter 13 angebrachten Bauteilen wie das Changiermittel 4 abgestützt wird. Die Entlastungszylindereinheiten 16.1 und 16.2, die zu beiden Seiten der Vorrichtung an den Schlitten 15 eingreifen, sind mit einer Steuereinrichtung 21 verbunden, durch welche die Entlastungszylindereinheit 16.1 und 16.2 in ihrer Stützwirkung steuerbar sind. Somit wird die während des Aufwickelns zwischen den Andrückwalzen 6.1 und 6.2 und den Spulen 9 wirkende Anlagekraft durch einen Gewichtsanteil von dem Gesamtgewicht bestimmt.The holder 13 is held by a carriage 15 and the carriage guide 14.1 and 14.2 vertically movable on the machine frame 12. The carriage 15 is held by a force transmitter 32 in the carriage guide 14.1 and 14.2 such that the pressure rollers 6.1 and 6.2, each with a predetermined contact force during the winding of the threads 1.1 and 1.2 abut the respective coil 9. The power transmitter 32 is formed in this embodiment by two relief cylinder units 16.1 and 16.2, by which the total weight of the two pressure rollers 6.1 and 6.2 and the holder 13 and additionally attached to the holder 13 components such as the traversing means 4 is supported. The relief cylinder units 16.1 and 16.2, which engage on both sides of the device to the carriage 15, are connected to a control device 21 through which the relief cylinder unit 16.1 and 16.2 are controllable in their supporting action. Thus, the force acting during the winding between the pressure rollers 6.1 and 6.2 and the coil 9 contact force is determined by a weight fraction of the total weight.

Bei dem in den Fig. 1 bis 4 gezeigten Ausführungsbeispiel werden in den Spulstellen 29.1 und 29.2 jeweils vier Fäden zu jeweils einer Spule gewickelt. Grundsätzlich ist die Anzahl der gleichzeitig gewickelten Fäden beispielhaft. So können pro Spulstelle 29.1 und 29.2 ein oder mehrere Fäden gleichzeitig gewickelt werden. In Praxis werden derartige Aufspulvorrichtungen jedoch ausschließlich zum Aufwickeln einer Vielzahl von Fäden eingesetzt.In the in the Fig. 1 to 4 In the exemplary embodiment shown, four threads are wound in each case into a coil in the winding stations 29.1 and 29.2. Basically, the number of simultaneously wound threads is exemplary. Thus, one or more threads can be wound simultaneously per winding unit 29.1 and 29.2. In practice, however, such winders are used exclusively for winding a plurality of threads.

Um einen Spulvorgang an den Spulspindeln 7.1 und 7.2 zu beginnen, werden die Andrückwalzen 6.1 und 6.2 durch den Schlitten 15 und die Entlastungszylindereinheit 6.1 und 6.2 in eine untere Position geführt. Nachdem die Fäden 1.1 und 1.2 der Fadenschar an den Spulhülsen gefangen und die Fadenreserven gewickelt wurden, beginnt die Spulreise. Während des Wickelns der Spulen 9 werden die Entlastungszylindereinheiten 16.1 und 16.2 derart geregelt und angesteuert, dass eine vorgegebene Anlagekraft an den Spulen 9 wirkt. Die Anlagekraft wird vorzugsweise während des Aufwickelns der Fäden an den Spulspindeln 7.1 und 7.2 konstant gehalten. Es ist jedoch auch möglich, während der Spulreise ein bestimmtes Kräfteprofil der Anlagekraft einzustellen. Hierzu wird beispielsweise der Entlastungsdruck in den Entlastungszylindereinheiten 16.1 und 16.2 auf einen vorgegebenen Wert eingestellt, sensiert und über die Steuereinrichtung 21 geregelt. Mit einer derartigen Druckregelung lässt sich auch vorteilhaft die Ausweichbewegung des Schlittens 15 steuern.To begin a winding operation on the winding spindles 7.1 and 7.2, the pressure rollers 6.1 and 6.2 are guided by the carriage 15 and the relief cylinder unit 6.1 and 6.2 in a lower position. After the threads have been caught 1.1 and 1.2 of the yarn sheet on the winding tubes and the thread reserves were wound, the winding cycle begins. During the winding of the coil 9, the Relief cylinder units 16.1 and 16.2 regulated and controlled so that a predetermined contact force acts on the coil 9. The contact force is preferably kept constant during the winding of the threads on the winding spindles 7.1 and 7.2. However, it is also possible to adjust a certain force profile of the contact force during the winding cycle. For this purpose, for example, the relief pressure in the relief cylinder units 16.1 and 16.2 set to a predetermined value, sensed and controlled by the control device 21. With such a pressure control can also be advantageous control the evasive movement of the carriage 15.

Die während des Aufwickelns der Fäden 1.1 und 1.2 aufgrund des Anwachsens der Spule 9 erforderliche Ausweichbewegung lässt sich grundsätzlich bei diesem Ausführungsbeispiel sowohl durch den beweglich gehaltenen Schlitten 15 als auch durch die beweglich gehaltenen Spulspindeln 7.1 und 7.2 ausführen. Durch die feste Anordnung der Andrückwalzen 6.1 und 6.2 an dem Halter 13 kann das Anwachsen der Spulen 9 durch Bewegung des Schlittens 15 synchron erfolgen.The deflection movement required during the winding of the threads 1.1 and 1.2 due to the growth of the bobbin 9 can basically be carried out in this exemplary embodiment both by the carriage 15 held movably and by the winding spindles 7.1 and 7.2 which are movably held. Due to the fixed arrangement of the pressure rollers 6.1 and 6.2 on the holder 13, the growth of the coils 9 can be effected synchronously by movement of the carriage 15.

Der Drehantrieb 30 der Spulrevolver 10.1 und 10.2 lässt sich zur Ausübung einer Ausweichbewegung vorzugsweise stufenweise oder kontinuierlich betreiben. Dabei sind beide Spulrevolver 10.1 und 10.2 durch ein Getriebemittel miteinander gekoppelt.The rotary drive 30 of the Spulrevolver 10.1 and 10.2 can be operated preferably in stages or continuously to exercise an evasive movement. Both spool turrets 10.1 and 10.2 are coupled together by a gear means.

In Fig. 4 ist das Ausführungsbeispiel in einer Betriebssituation dargestellt, bei welchem die Spulspindeln 7.1 und 7.2 durch Aktivierung des Drehantriebes 30 der Spulrevolver 10.1 und 10.2 zum Spulenwechsel verschwenkt sind. Dabei lösen sich die Vollspulen 9 vom Kontakt der Andrückwalzen 6.1 und 6.2. In dieser Phase wird gleichzeitig durch die Steuereinrichtung 21 eine Beschleunigung der Andrückwalzen 6.1 und 6.2 über den Walzenantrieb 17 eingeleitet. Beide Andrückwalzen 6.1 und 6.2 werden auf eine vorgegebene Umfangsgeschwindigkeit synchron beschleunigt, die im Verhältnis zu den Spulumfangsgeschwindigkeiten der weggeschwenkten Vollspulen an den beiden Spulspindeln 7.1 und 7.2 größer ist. Dadurch wird an jeden der zu den Vollspulen 9 der Spulspindel 7.1 und 7.2 zulaufenden Fäden jeweils eine antreibende Fadenreibung erzeugt. Die Umfangsgeschwindigkeit der Andrückwalzen 6.1 und 6.2 ist somit höher als die Fadenlaufgeschwindigkeit der einzelnen Fäden. Dieser Zustand bleibt während des Spulwechsels erhalten, und wird in Abhängigkeit von der Drehbewegung des Spulrevolvers gesteuert. Sobald ein neuer Kontakt zwischen den Andrückwalzen 6.1 und 6.2 und den neu zu bildenden Spulen der Spulspindel 11.1 und 11.2 erfolgt, werden die Andrückwalzen 6.1 und 6.2 auf den Ursprungswert zum kontinuierlichen Aufwickeln der Fäden zurückverstellt.In Fig. 4 the embodiment is shown in an operating situation in which the winding spindles 7.1 and 7.2 are pivoted by activating the rotary drive 30 of the winding turret 10.1 and 10.2 for bobbin change. In this case, the full bobbins 9 detach from the contact of the pressure rollers 6.1 and 6.2. In this phase, an acceleration of the pressure rollers 6.1 and 6.2 via the roller drive 17 is simultaneously initiated by the control device 21. Both pressure rollers 6.1 and 6.2 are synchronously accelerated to a predetermined peripheral speed, the larger in relation to the Spulumfangsgeschwindigkeiten the weggeschwenkten full bobbins on the two winding spindles 7.1 and 7.2 is. As a result, each one of the full bobbins 9 of the winding spindle 7.1 and 7.2 tapering threads each generates a driving yarn friction. The peripheral speed of the pressure rollers 6.1 and 6.2 is thus higher than the yarn running speed of the individual threads. This condition is maintained during the spool change, and is controlled in response to the rotation of the spool turret. As soon as a new contact between the pressure rollers 6.1 and 6.2 and the newly formed coils of the winding spindle 11.1 and 11.2, the pressure rollers are 6.1 and 6.2 zurückverstellt back to the original value for continuous winding of the threads.

Zur Erläuterung des Antriebskonzeptes des zuvor beschriebenen Ausführungsbeispiels der erfindungsgemäßen Aufspulvorrichtung ist nachfolgend anhand der Fig. 5 eine mögliche Ausführung erläutert. Aufgrund der Übersichtlichkeit sind in Fig. 5 nur die zum Antreiben erforderlichen Vorrichtungsteile der Spulstellen 29.1 und 29.2 schematisch dargestellt.To explain the drive concept of the previously described embodiment of the winding device according to the invention is described below with reference to the Fig. 5 a possible embodiment explained. Due to the clarity are in Fig. 5 only the device parts required for driving the winding units 29.1 and 29.2 shown schematically.

Bei dem Antriebskonzept nach Fig. 5 ist in der Spulstelle 29.1 die Spulspindel 7.1 mit dem Spindelantrieb 23.1 gekoppelt. Dem Spindelantrieb 23.1 ist ein Steuergerät 24.1 zugeordnet, das mit übergeordneten Steuereinrichtungen 21 verbunden ist. Die an der Spulspindel 7.1 gewickelte Spule 9 ist hierbei gestrichelt dargestellt. Am Umfang der Spule 9 liegt die Andrückwalze 6.1 an, die ebenfalls gestrichelt dargestellt ist. Die Andrückwalze 6.1 weist ein Walzenende 18.1 auf. An dem Walzenende 18.1 ist ein Drehzahlsensor 20 zugeordnet, durch welchen die Drehgeschwindigkeit der Andrückwalze 6.1 erfassbar ist. Der Drehzahlsensor 20 ist mit der Steuereinrichtung 21 verbunden.According to the drive concept Fig. 5 is in the winding unit 29.1 the winding spindle 7.1 coupled to the spindle drive 23.1. The spindle drive 23.1 is associated with a control unit 24.1, which is connected to higher-level control devices 21. The wound on the winding spindle 7.1 coil 9 is shown here by dashed lines. At the periphery of the coil 9 is the pressure roller 6.1, which is also shown in dashed lines. The pressure roller 6.1 has a roller end 18.1. At the end of the roller 18.1 a speed sensor 20 is assigned, by which the rotational speed of the pressure roller 6.1 can be detected. The rotational speed sensor 20 is connected to the control device 21.

Das Walzenende 18.1 der Andrückwalze 6.1 ist mit dem Walzenende 18.2 der zweiten Andrückwalze 6.2 durch ein Getriebemittel 19 gekoppelt. Das Getriebemittel 19 in diesem Ausführungsbeispiel durch einen Riemen oder eine Kette mechanisch ausgebildet, so dass beide Andrückwalzen 6.1 und 6.2 beider Spulstellen mit gleicher Drehzahl gegensinnig umlaufen. Zum Antrieb des Getriebemittels 19 ist eine Elektromotor 25 mit einem Antriebsrad 33 verbunden. Das Antriebsrad 33 ist mit dem Getriebemittel 19 gekoppelt. Dem Elektromotor 25 ist ein Steuergerät 27 zugeordnet, welches mit der Steuereinrichtung 21 gekoppelt ist. Das Steuergerät 27, der Elektromotor 25, das Antriebsrad 33 und das Getriebemittel 19 bilden somit den Walzenantrieb 17.The roller end 18.1 of the pressure roller 6.1 is coupled to the roller end 18.2 of the second pressure roller 6.2 by a gear means 19. The transmission means 19 in this embodiment mechanically formed by a belt or a chain, so that both pressure rollers rotate 6.1 and 6.2 both winding units with the same speed in opposite directions. To drive the transmission means 19 an electric motor 25 is connected to a drive wheel 33. The drive wheel 33 is coupled to the transmission means 19. The electric motor 25 is associated with a control unit 27 which is coupled to the control device 21. The control unit 27, the electric motor 25, the drive wheel 33 and the gear means 19 thus form the roller drive 17th

Zum Antrieb der Spulrevolver 10.1 und 10.2 sind die jeweiligen Revolverachsen 34.1 und 34.2 durch eine Getriebemittel 35 beispielsweise eine Kette miteinander gekoppelt. Dabei wird die Revolverachse 34.1 durch den Drehantrieb 30 angetrieben. Der Drehantrieb 30 wird durch das zugeordnete Steuergerät 36 gesteuert, wobei das Steuergerät 36 mit der zentralen Steuereinrichtung 21 verbunden ist.To drive the winding turret 10.1 and 10.2, the respective turret axes 34.1 and 34.2 are coupled together by a gear means 35, for example, a chain. In this case, the turret axis 34.1 is driven by the rotary drive 30. The rotary drive 30 is controlled by the associated control unit 36, wherein the control unit 36 is connected to the central control device 21.

In der Spulstelle 29.1 wird die an dem Spulrevolver 10.1 gehaltene zweite Spulspindel 11.1 durch den Spindelantrieb 31.1 und dem zugeordneten Steuergerät 24.3 angetrieben. Das Steuergerät 24.3 ist mit der Steuereinrichtung 21 gekoppelt.In the winding unit 29.1, the second winding spindle 11.1 held on the winding turret 10.1 is driven by the spindle drive 31.1 and the associated control device 24.3. The control unit 24.3 is coupled to the control device 21.

In der Spulstelle 29.2 wird die Spulspindel 7.2 durch den Spindelantrieb 22.2 gegen den Uhrzeigersinn angetrieben, um die Fäden zu Spulen zu wickeln. Hierbei dreht sich die Andrückwalze 6.2 am Umfang der Spulen im Uhrzeigersinn mit entsprechenden Drehzahl der Andrückwalze 6.1. Die Drehübertragung zwischen den Andrückwalzen 6.1 und 6.2 erfolgt durch das Getriebemittel 19. In beiden Spulstellen 29.1 und 29.2 werden die Fäden synchron gewickelt, so dass an jeder Spulspindel 7.1 und 7.2 ein identischer Aufbau der Spulen 9 stattfindet.In the winding unit 29.2, the winding spindle 7.2 is driven by the spindle drive 22.2 counterclockwise to wind the threads into coils. In this case, the pressure roller 6.2 rotates clockwise at the circumference of the coils with the corresponding speed of the pressure roller 6.1. The rotation transmission between the pressure rollers 6.1 and 6.2 is carried out by the gear means 19. In both winding units 29.1 and 29.2, the threads are wound synchronously, so that at each winding spindle 7.1 and 7.2, an identical structure of the coil 9 takes place.

Die in der Spulstelle 29.2 in der Ruhestellung gehaltene Spulspindel 11.2 lässt sich über den Spindelantrieb 31.2 und dem zugeordneten Steuergerät 24.4 antreiben. Das Steuergerät 24.4 ist mit der Steuereinrichtung 21 verbunden.The winding spindle 11.2 held in the winding position 29.2 in the rest position can be driven via the spindle drive 31.2 and the associated control device 24.4. The control unit 24.4 is connected to the control device 21.

Um eine konstante Aufwickelgeschwindigkeit der Fäden zu erhalten, wird die Drehgeschwindigkeit der Andrückwalze 6.1 durch den Drehzahlsensor 20 kontinuierlich erfasst und der Steuereinrichtung 21 aufgegeben. In der Steuereinrichtung 21 ist eine Soll-Drehzahl der Andrückwalze 6.1 hinterlegt. Sobald zwischen der sensierten Ist-Drehgeschwindigkeit der Andrückwalze 6.1 und der hinterlegten Soll-Drehgeschwindigkeit der Andrückwalze 6.1 eine unzulässige Abweichung erfasst wird, wird ein Steuersignal generiert und den Steuergeräten 24.1 und 24.2 aufgegeben. Die Steuergeräte 24.1 und 24.2 verändern die Antriebsdrehzahlen der Spindelantriebe 23.1 und 23.2 in dem gewünschten Sinn. Somit lässt sich während des gesamten Aufwickelns der Fäden eine konstante Umfangsgeschwindigkeit der Spulen einstellen. Die Spindelantriebe 23.1 und 23.2 werden hierbei vorzugsweise durch Asynchronmotoren oder durch Synchronmotoren gebildet.In order to obtain a constant winding speed of the threads, the rotational speed of the pressure roller 6.1 is continuously detected by the speed sensor 20 and the control device 21 abandoned. In the control device 21 is a target speed of the pressure roller 6.1 deposited. As soon as between the sensed actual rotational speed of the pressure roller 6.1 and the stored target rotational speed of the pressure roller 6.1 an impermissible deviation is detected, a control signal is generated and the control units 24.1 and 24.2 abandoned. The control units 24.1 and 24.2 change the drive speeds of the spindle drives 23.1 and 23.2 in the desired sense. Thus, a constant peripheral speed of the coils can be adjusted during the entire winding of the threads. The spindle drives 23.1 and 23.2 are preferably formed by asynchronous motors or by synchronous motors.

Durch den Elektromotor 25 lässt sich überlagert ein Lastverhältnis zwischen den Walzenantrieb der Andrückwalzen 6.1 und 6.2 und den Antrieben der Spulspindeln 7.1 und 7.2 einstellen. Somit können die Andrückwalzen 6.1 und 6.2 sowohl antreibend als auch bremsend auf die Spulenoberfläche der Spulen wirken. Das Lastverhältnis wird durch die Steuereinrichtung 21 aufgegeben und geregelt.By the electric motor 25 can be superimposed on a load ratio between the roller drive of the pressure rollers 6.1 and 6.2 and the drives of the winding spindles 7.1 and 7.2 set. Thus, the pressure rollers 6.1 and 6.2 can act both driving and braking on the coil surface of the coils. The load ratio is given up and regulated by the control device 21.

Für den Fall, dass die gewickelten Spulen einen vorbestimmten maximalen Durchmesser erreicht haben, wird über die Steuereinrichtung 21 und dem Steuergerät 36 der Drehantrieb 30 aktiviert, so dass die Spulrevolver 10.1 und 10.2 sich gegensinnig derart bewegen, dass die Spulspindeln 7.1 und 7.2 mit den Vollspulen von den Andrückwalzen 6.1 und 6.2 weggeführt werden. Gleichzeitig wird über die Steuereinrichtung 21 und dem Steuergerät 27 der Elektromotor 25 des Walzenantriebes derart angesteuert, dass die Andrückwalzen 6.1 und 6.2 auf eine erhöhte Umfangsgeschwindigkeit beschleunigt werden. Durch das Getriebemittel 19 wird erreicht, dass beide Andrückwalzen 6.1 und 6.2 synchron beschleunigt werden, so dass die Einwirkung auf alle Fäden gleich erfolgt. Somit lassen sich vorteilhaft Spulwechselvorgänge ohne Auswirkung auf die vorgeordneten Behandlungseinrichtungen oder Spinneinrichtungen selbst bei einer Vielzahl von Fäden ohne wesentliche Auswirkung ausführen.In the event that the wound coils have reached a predetermined maximum diameter, the rotary drive 30 is activated via the control device 21 and the control unit 36, so that the spool turrets 10.1 and 10.2 move in opposite directions such that the winding spindles 7.1 and 7.2 with the full bobbins be led away from the pressure rollers 6.1 and 6.2. At the same time, the electric motor 25 of the roller drive is controlled in such a way via the control device 21 and the control unit 27 that the pressure rollers 6.1 and 6.2 are accelerated to an increased peripheral speed. By the gear means 19 is achieved that both pressure rollers 6.1 and 6.2 are accelerated synchronously, so that the action on all threads is the same. Thus, it is advantageous to perform winder exchanges without any effect on the upstream treatment devices or spinning devices even with a plurality of filaments without significant effect.

In Fig. 6 ist ein weiteres Ausführungsbeispiel eines Antriebskonzeptes für das in Fig. 1 gezeigte Ausführungsbeispiel er erfindungsgemäßen Vorrichtung dargestellt.

Der Walzenantrieb der Andrückwalzen 6.1 und 6.2 wird durch die beiden Elektromotoren 28.1 und 28.2 und einem den Elektromotoren zugeordneten Steuergerät 27 gebildet. Das Steuergerät 27 ist mit der Steuereinrichtung 21 gekoppelt, so dass jeder der Elektromotoren 28.1 und 28.2 mit gleichen Einstellungen betrieben werden kann, um die Andrückwalzen 6.1 und.6.2 anzutreiben.In Fig. 6 is another embodiment of a drive concept for in Fig. 1 shown embodiment he illustrated device according to the invention. This in Fig. 6 shown drive concept is essentially identical to the previous embodiment of a drive concept according to Fig. 5 , In that regard, reference can be made to the preceding description, so that at this point only the differences are mentioned. The roller drive of the pressure rollers 6.1 and 6.2 is formed by the two electric motors 28.1 and 28.2 and a controller 27 associated with the electric motors. The control device 27 is coupled to the control device 21, so that each of the electric motors 28.1 and 28.2 can be operated with the same settings in order to drive the pressure rollers 6.1 and 6.2.

Des weiteren sind gegenüber dem vorhergehenden Ausführungsbeispiel nach Fig. 5 die Spindelantriebe 23.1 und 23.2 der Spulspindeln 7.1 und 7.2 jeweils durch ein Steuergerät 24.1 gesteuert. Die Spindelantriebe 23.1 und 23.2 können dabei als Synchronmotoren oder als Asynchronmotoren ausgebildet sein. Ebenso sind den Spindelantrieben 31.1 und 31.2 ein Steuergerät 24.2 zugeordnet. Die Steuergeräte 24.1 und 24.2 sind mit der Steuereinrichtung 21 verbunden.Furthermore, according to the previous embodiment Fig. 5 the spindle drives 23.1 and 23.2 of the winding spindles 7.1 and 7.2 are each controlled by a control unit 24.1. The spindle drives 23.1 and 23.2 can be designed as synchronous motors or asynchronous motors. Likewise, the spindle drives 31.1 and 31.2 associated with a control unit 24.2. The control devices 24.1 and 24.2 are connected to the control device 21.

Der Drehantrieb der Spulrevolver 10.1 und 10.2 wird durch zwei separate Drehantriebe 30.1 und 30.2 gebildet, die gemeinsam über ein Steuergerät 36 ansteuerbar sind. Das Steuergerät 36 ist mit der Steuereinrichtung 1 verbunden.The rotary drive of the winding turret 10.1 and 10.2 is formed by two separate rotary actuators 30.1 and 30.2, which are jointly controlled by a control unit 36. The control unit 36 is connected to the control device 1.

In Fig. 7 ist ein weiteres Ausführungsbeispiel der erfindungsgemäßen Vorrichtung schematisch in einer Vorderansicht dargestellt. Das Ausführungsbeispiel nach Fig. 7 ist im wesentlichen identisch zu dem Ausführungsbeispiel nach Fig. 1, so dass zu der vorhergehenden Beschreibung Bezug genommen wird und an dieser Stelle nur die Unterschiede aufgezeigt werden. Hierbei haben die Bauteile mit gleichen Funktionen identische Bezugszeichen erhalten.In Fig. 7 a further embodiment of the device according to the invention is shown schematically in a front view. The embodiment according to Fig. 7 is essentially identical to the embodiment according to Fig. 1 so that reference is made to the foregoing description and at this point only the differences are shown. Here, the components having identical functions have been given identical reference numerals.

Gegenüber dem vorhergehenden Ausführungsbeispiel werden bei den in Fig. 7 dargestellten Ausführungsbeispiel die Andrückwalzen 6.1 und 6.2 durch zwei separate Schwingen 37.1 und 37.2 schwenkbar an dem Maschinengestell 12 gehalten. Den Schwingen 37.1 und 37.2 ist jeweils ein Hubsensor 38.1 und 38.2 zugeordnet, durch welche eine Bewegung der Andrückwalzen 6.1 und 6.2 sensierbar ist. Die Hubsensoren 38.1 und 38.2 sind über Signalleitungen mit der hier nicht dargestellten Steuereinrichtung verbunden.Compared to the previous embodiment are in the in Fig. 7 illustrated embodiment, the pressure rollers 6.1 and 6.2 held by two separate rockers 37.1 and 37.2 pivotally mounted on the machine frame 12. The rockers 37.1 and 37.2 are each assigned a stroke sensor 38.1 and 38.2 by which a movement of the pressure rollers 6.1 and 6.2 can be sensed. The stroke sensors 38.1 and 38.2 are connected via signal lines with the control device, not shown here.

Den Andrückwalzen 6.1 und 6.2 sind im Fadenlauf jeweils separate Changiermittel 4.1 und 4.2 zugeordnet. Jedes der Changiermittel 4.1 und 4.2 ist in diesem Ausführungsbeispiel als eine Flügelchangierung ausgeführt. Dabei wird jeder der Fäden in seiner Spulstelle mittels gegensinnig angetriebenen Flügeln hin- und hergeführt.The pressure rollers 6.1 and 6.2 are each assigned in the yarn path separate traversing 4.1 and 4.2. Each of the traversing means 4.1 and 4.2 is designed in this embodiment as a Flügelchangierung. Each of the threads is guided back and forth in its winding unit by means of oppositely driven wings.

Alle hier nicht weiter erläuterten und dargestellten Bauteile und Antriebe sind identisch zu dem vorhergehenden Ausführungsbeispiel ausgebildet.All components and drives not further explained and illustrated here are identical to the previous exemplary embodiment.

Bei der dargestellten Betriebssituation werden jeweils mehrere Spulen 9 an den in Betriebsstellung befindlichen Spulspindeln 7.1 und 7.2 gewickelt. Während des Aufwickelns der Fäden 1.1 und 1.2 wird die Ausweichbewegung durch den Drehantrieb der Spulrevolver 10.1 und 10.2 ausgeführt. Hierzu wird die Hubbewegung der Andrückwalzen 6.1 und 6.2 durch die zugeordneten Hubsensoren 38.1 und 38.2 erfasst und der Steuereinrichtung signalisiert. Sobald eine der Andrückwalzen 6.1 oder 6.2 eine von einem vorgegebenen Sollbereich abweichende IstStellung einnimmt, wird innerhalb der Steuereinrichtung ein Steuerbefehl zur Aktivierung des Drehantriebes der Spulrevolver 10.1 und 10.2 ausgelöst. Die Drehbewegung des Spulrevolvers 10.1 und 10.2 erfolgt so lange bis die Andrückwalzen 6.1 und 6.2 ihren Soll-Bereich wieder eingenommen haben.In the illustrated operating situation several coils 9 are wound on the winding spindles 7.1 and 7.2 in the operating position. During the winding of the threads 1.1 and 1.2, the evasive movement is performed by the rotary drive of the winding turret 10.1 and 10.2. For this purpose, the lifting movement of the pressure rollers 6.1 and 6.2 detected by the associated stroke sensors 38.1 and 38.2 and the control device signals. As soon as one of the pressure rollers 6.1 or 6.2 assumes an actual position deviating from a predetermined nominal range, a control command for activating the rotary drive of the reel turrets 10.1 and 10.2 is triggered within the control device. The rotational movement of the winding turret 10.1 and 10.2 takes place until the pressure rollers 6.1 and 6.2 have resumed their desired range.

Der Antrieb der Andruckwalzen 6.1 und 6.2 ist identisch zu den vorhergehenden Ausführungsbeispielen ausgeführt, so dass während eines Spulenwechsels beide Andrückwalzen 6.1 und 6.2 auf eine überhöhte Umfangsgeschwindigkeit beschleunigt werden, die größer ist als jede der Spulgeschwindigkeiten der weggeführten Vollspulen an den Spulspindeln 7.1 und 7.2.The drive of the pressure rollers 6.1 and 6.2 is identical to the preceding embodiments, so that during a bobbin change both pressure rollers 6.1 and 6.2 are accelerated to an excessive peripheral speed which is greater than each of the winding speeds of the swept away full bobbins on the winding spindles 7.1 and 7.2.

Das erfindungsgemäße Verfahren sowie die erfindungsgemäße Vorrichtung ist insbesondere zum Aufwickeln frisch gesponnener Fäden geeignet. Hierbei können die Fäden aus einer Spinneinrichtung oder aus einer Behandlungseinrichtung abgezogen werden. Durch die Gewährleistung einer im wesentlichen konstanten Abzugskraft der Fäden, insbesondere während eines Spulwechselvorgangs, lässt sich eine gleichmäßige Behandlung aller Fäden in den vorgeschalteten Behandlungseinrichtung bzw. der Spinneinrichtung erreichen.The inventive method and the device according to the invention is particularly suitable for winding freshly spun threads.
