Description

Die Erfindung betrifft eine Kreuzspulen herstellende Textilmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a cheese making Textile machine according to the preamble of claim 1.

Solche Kreuzspulen herstellenden Textilmaschinen sind in verschiedenen Ausführungsformen bekannt.Such textile machines producing cross-wound bobbins are in known various embodiments.

Die DE 39 04 065 C2 beschreibt beispielsweise einen Kreuzspulautomaten, dessen Spulstellen jeweils eine Einrichtung zum Regeln der Fadenspannung während des Spulprozesses aufweisen.
Diese bekannten Einrichtungen besitzen eine Vorrichtung zum Erfassen der Drehzahl der Kreuzspule, eine Vorrichtung, zum Berechnen des augenblicklichen Durchmessers der Kreuzspule sowie eine Speichervorrichtung mit einem vorgegebenen Fadenspannungsprogramm.
Bei derartig ausgestatteten Einrichtungen wird der Fadenspanner während der Spulenreise dabei so angesteuert, daß die Fadenspannung mit größer werdendem Durchmesser der Kreuzspule allmählich abnimmt.DE 39 04 065 C2 describes, for example, an automatic winder, the winding stations of which each have a device for regulating the thread tension during the winding process.
These known devices have a device for detecting the rotational speed of the cheese, a device for calculating the current diameter of the cheese and a storage device with a predetermined thread tension program.
In devices equipped in this way, the thread tensioner is controlled during the bobbin travel so that the thread tension gradually decreases as the diameter of the package increases.

Durch die EP 0 350 081 A1 ist weiter eine Einrichtung bekannt, bei der die Spulgeschwindigkeit der Spulaggregate in Abhängigkeit von der Restfadenlänge der Vorlagespulen gesteuert wird. Die Einrichtungen weisen außerdem jeweils einen Fadenspanner auf, der während des Spulprozesses im Bedarfsfall durch den Spulstellenrechner definiert ansteuerbar ist.A device is also known from EP 0 350 081 A1, at which the winding speed of the winding units in Controlled depending on the remaining thread length of the supply spools becomes. The facilities also each have one Thread tensioner on during the winding process if necessary can be controlled in a defined manner by the winding unit computer.

Im Zusammenhang mit Kreuzspulautomaten sind Fadenspanner, die eine rotierbar angeordnete Bremstelleranordnung aufweisen, wobei einer der Bremsteller mittels einer Tauchspule axial beaufschlagbar ist, seit langem bekannt. Die DE 41 30 301 A1 beschreibt beispielsweise einen solchen, in der Praxis vielfach bewährten Fadenspanner.In connection with automatic winder, thread tensioners are have a rotatable brake actuator arrangement, wherein one of the brake actuators axially by means of a moving coil has been known for a long time. DE 41 30 301 A1 for example, describes one of these, in practice in many cases proven thread tensioner.

Durch die DE 39 02 182 A1 ist ein Kreuzspulautomat mit einer Vielzahl von Spulstellen bekannt, die jeweils separate Spulstellenrechner aufweisen, welche an eine zentrale Steuereinheit der Textilmaschine angeschlossen sind. Mit dieser zentralen Steuereinheit der Textilmaschine steht außerdem ein die Spulstellen versorgendes Serviceaggregat in Verbindung. Das Serviceaggregat kann über die zentrale Steuereinheit und die Spulstellenrechner den Spulantrieb jeder Spulstelle so ansteuern, daß während des Wechselvorganges Kreuzspule/Leerhülse die Fadenführungstrommel mit einer gegenüber dem 'normalen' Spulprozeß geänderten, d.h. reduzierten Umfangsgeschwindigkeit rotiert.From DE 39 02 182 A1 is an automatic winder with a A variety of winding units are known, each separate Have winding station computer, which to a central Control unit of the textile machine are connected. With this central control unit of the textile machine is also a the service unit supplying the winding units. The service unit can via the central control unit and the winding unit computer the winding drive of each winding unit like this control that during the change process Cheese / empty tube the thread guide drum with a compared to the 'normal' winding process, i.e. reduced peripheral speed rotates.

Die DE 42 21 504 A1 beschreibt einen Kreuzspulautomaten, dessen Arbeitsstellen über eine Busleitung mit einem Servicefahrzeug verbunden sind.
Wenn an einer der Arbeitsstellen ein Bedienbedarf auftritt, setzt die betreffende Arbeitsstelle ein optisches Signal, das von dem vor den Arbeitsstellen patrouillierenden Servicefahrzeug erkannt und nach dessen Positionierung an dieser Arbeitsstelle durch ein Lichtsignal an die Arbeitsstelle bestätigt wird. Durch dieses Lichtsignal wird die betreffende Arbeitsstelle aktiviert, so daß anschließend vom Servicefahrzeug aus, über die Busleitung, Arbeitsbefehle, beispielsweise Antriebswalze rückwärtsdrehen, Arbeitsstelle abblasen oder dergleichen an die betreffende Arbeitsstelle abgesetzt werden können.DE 42 21 504 A1 describes an automatic winder, the workstations of which are connected to a service vehicle via a bus line.
If there is a need for operation at one of the workplaces, the workstation in question sets an optical signal which is recognized by the service vehicle patrolling in front of the workplaces and which is confirmed at the workstation by a light signal to the workstation. This light signal activates the relevant work station, so that work commands, for example, turning the drive roller backwards, blowing off work stations or the like, can then be set down from the service vehicle via the bus line.

Ausgehend vom vorgenannten Stand der Technik, liegt der Erfindung die Aufgabe zugrunde, den in Verbindung mit Kreuzspulautomaten üblichen automatischen Wechselvorgang Kreuzspule/Leerhülse zu verbessern. Based on the aforementioned prior art, the Invention based on the object in connection with Automatic winding machine usual automatic change process To improve the package / empty tube.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung gelöst, wie sie im Anspruch 1 beschrieben ist.This object is achieved by a device solved, as described in claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of Subclaims.

Die erfindungsgemäße Ausbildung hat insbesondere den Vorteil, daß die Einstellung des über den Spulstellenrechner angesteuerten Fadenspanners der Spulstelle sowohl während des Spulprozesses als auch während des Wechselvorganges Kreuzspule/Leerhülse jeweils speziell an die vorliegenden Bedürfnisse angepaßt werden kann.
Das heißt, insbesondere bei den im Zusammenhang mit dem Wechselvorgang Kreuzspule/Leerhülse durchzuführenden Spulenhandhabungsmaßnahmen kann die jeweils erforderliche Fadenspannung mittels des an der Spulstelle angeordneten Fadenspanners entsprechend vom Steuerungsrechner des Serviceaggregates vorgegebener Parameter optimal angepaßt werden. Es ist dabei möglich, während des Wechselvorganges auch kleinere Einstellungen zu wählen als die, die während des Spulprozesses üblich sind.The design according to the invention has the particular advantage that the setting of the thread tensioner of the winding unit controlled via the winding unit computer can be specifically adapted to the present requirements both during the winding process and during the cross-wound / empty tube changing process.
That is to say, in particular in the case of the bobbin handling measures to be carried out in connection with the bobbin / empty tube change process, the thread tension required in each case can be optimally adapted by means of the thread tensioner arranged at the winding point in accordance with parameters specified by the control computer of the service unit. It is possible to choose smaller settings during the changing process than those that are common during the winding process.

Da der Steuerungsrechner des Serviceaggregates den Fadenspanner der Spulstelle über den Maschinenbus exakt ansteuern kann, ist es nicht notwendig, daß das Serviceaggregat, um auch während des Wechselvorganges eine genaue Fadenspannung einhalten zu können, eine eigene Fadenspanneinrichtung aufweist.As the control computer of the service unit the thread tensioner can precisely control the winding unit via the machine bus it is not necessary for the service unit to operate during of the change process to maintain an exact thread tension can have their own thread tensioning device.

In vorteilhafter Ausgestaltung der Erfindung ist vorgesehen (Anspruch 2), daß die vom Steuerungsrechner des Serviceaggregates vorgegebbaren, über den Fadenspanner auf den Faden aufbringbaren Fadenspannungswerte entsprechend den jeweiligen Spulenhandhabungsmaßnahmen des Serviceaggregates individuell anpaßbar sind. Die Fadenspannung wird folglich auch während des Wechselvorganges automatisch optimal eingestellt und richtet sich beispielsweise danach, ob die Kreuzspule eine Kopfreserve in Form einer über die Stirnseite verlaufenden Sehne oder eine Kopfreservewicklung in Form einer auf die Hülsenspitze aufgebrachten sogenannten Topcone-Wicklung erhalten soll. Auch bei der Erstellung der Fußreservewicklung auf der Leerhülse wird automatisch eine spezielle, optimale Fadenspannung eingestellt.In an advantageous embodiment of the invention it is provided (Claim 2) that the control computer of the Service units can be specified via the thread tensioner on the Thread attachable thread tension values according to the respective coil handling measures of the service unit are individually adaptable. The thread tension will consequently also automatically set optimally during the change process and depends, for example, on whether the package is a Head reserve in the form of a head reserve Tendon or a head reserve winding in the form of one on the So-called top-cone winding applied to the sleeve tip should receive. Also when creating the foot reserve winding a special, optimal one is automatically placed on the empty tube Thread tension set.

Die erforderlichen Parameter zur Einstellung des Fadenspanners können dabei vom Steuerungsrechner des Serviceaggregates entweder, wie in Anspruch 3 beschrieben, in absoluten Werten vorgegeben werden oder, wie in Anspruch 4 dargelegt, als prozentuale Abweichung von einstellbaren Sollwerten.The parameters required to set the thread tensioner can from the control computer of the service unit either, as described in claim 3, in absolute values be specified or, as set out in claim 4, as Percentage deviation from adjustable setpoints.

Eine Vorgabe der Einstellparameter als prozentuale Abweichung von Sollwerten ist dabei besonders vorteilhaft, da auf diese Weise auch während des Spulprozesses eine Abstimmung der Einstellung des Fadenspanners auf das momentan verarbeitete Garn, zum Beispiel bezüglich der Reißfestigkeit, möglich ist.A specification of the setting parameters as a percentage deviation of setpoints is particularly advantageous because of these Way also during the winding process Setting the thread tensioner to the currently processed Yarn, for example in terms of tear strength, is possible.

Weitere Einzelheiten der Erfindung sind einem nachfolgend anhand der Zeichnungen erläuterten Ausführungsbeispiel entnehmbar.Further details of the invention are as follows exemplary embodiment explained with reference to the drawings removable.

Des weiteren verfügen solche Kreuzspulautomaten 1 über eine Zentralsteuereinheit 37, die über einen Maschinenbus 40 sowohl mit den separaten Spulstellenrechnern 39 der einzelnen Spulstellen 2 als auch mit dem Steuerungsrechner 38 eines die Spulstellen 2 bedienenden Serviceaggregates 23 verbunden ist. Furthermore, such cross winding machines 1 have one Central control unit 37, both via a machine bus 40 with the separate winding unit computers 39 of the individual Spooling stations 2 as well as with the control computer 38 Service units 23 serving winding stations 2 is connected.

Wie insbesondere aus Fig. 2 ersichtlich, ist das Serviceaggregat 23 mit Fahrwerken 24, 25 auf maschinenlangen Laufbahnen 26, 27, die oberhalb der Spulstellen 2 angeordnet sind, verfahrbar gelagert.
Das Serviceaggregat 23 sorgt nicht nur dafür, daß die auf den Spulstellen fertiggestellten Kreuzspulen 11 auf die Kreuzspulentransporteinrichtung 21 ausgerollt werden, sondern es wechselt auch jeweils selbstständig eine Leerhülse 28 in den Spulenrahmen der betreffenden Spulstelle 2 ein. Die Leerhülse 28 entnimmt das Serviceaggregat 23 dabei vorzugsweise einem spulstelleneigenen Leerhülsenmagazin 22.As can be seen in particular from FIG. 2, the service unit 23 is movably mounted with carriages 24, 25 on machine-long tracks 26, 27 which are arranged above the winding units 2.
The service unit 23 not only ensures that the cross-wound bobbins 11 finished on the winding units are rolled out onto the cross-wound bobbin transport device 21, but it also independently changes an empty tube 28 into the bobbin frame of the winding unit 2 in question. The service unit 23 preferably takes the empty tube 28 from an empty tube magazine 22 that is provided in the winding unit.

Von dem insgesamt relativ umfangreichen und an sich bekannten Spulen- und Hülsentransportsystem 3 ist in Fig. 2 lediglich die maschinenlange Spulenzuführstrecke 4, die hinter den Spulstellen 2 verlaufende Reversierstrecke 5, eine der zu den Spulstellen 2 führenden Quertransportstrecken 6 sowie die Hülsenrückführstrecke 7 dargestellt.
Die über die Zuführstrecke 4 angelieferten und über die Reversierstreckr 5 auf die Querstrecken 6 verteilten Spinnkopse 9 werden in den Abspulstellungen 10, die sich im Bereich der Quertransportstrecken 6 an den Spulstellen 2 befinden, zu großvolumigen Kreuzspulen 11 umgespult.Of the relatively extensive and generally known bobbin and tube transport system 3, only the machine-long bobbin feed path 4, the reversing path 5 running behind the bobbin units 2, one of the transverse transport lines 6 leading to the bobbin units 2 and the tube return path 7 are shown in FIG. 2.
The spinning heads 9, which are supplied via the feed section 4 and distributed over the reversing section 5 to the transverse sections 6, are rewound into large-volume cross-wound bobbins 11 in the unwinding positions 10, which are located in the region of the transverse transport sections 6 at the winding stations 2.

Die einzelnen Spulstellen 2 verfügen dabei, wie bekannt und daher nur angedeutet, über verschiedene Einrichtungen, die einen ordnungsgemäßen Betrieb dieser Arbeitsstellen gewährleisten.
In Fig. 2 ist mit 30 der vom Spinnkops 9 zur Kreuzspule 11 laufende Faden, mit 12 eine Saugdüse und mit 42 ein Greiferrohr gekennzeichnet. Eine Spleißeinrichtung trägt die Bezugszahl 13, eine Fadenspanneinrichtung die Bezugszahl 14. Außerdem verfügen solche Spulstellen über einen Fadenreiniger 15 mit Fadenschneideinrichtung sowie über eine Paraffiniereinrichtung 16. The individual winding units 2 have, as is known and therefore only hinted at, various devices which ensure proper operation of these work stations.
In Fig. 2, 30 is the thread running from the spinning cop 9 to the cheese 11, 12 is a suction nozzle and 42 is a gripper tube. A splicing device bears the reference number 13, a thread tensioning device the reference number 14. In addition, such winding units have a thread cleaner 15 with a thread cutting device and a paraffinizing device 16.

Die Antriebstrommel, die die Kreuzspule 11 während des Spulvorganges über Reibschluß antreibt, trägt die Bezugszahl 17. Während des Spulvorganges ist die Kreuzspule 11 in einem Spulenrahmen 18 gehalten, der um eine Achse 19 schwenkbar gelagert ist. Unterhalb des Spulenrahmens 18 ist, ebenfalls um die Schwenkachse 19 begrenzt drehbar, ein Schwenkblech 20 angeordnet, über das die fertigen Kreuzspulen auf die hinter den Spulstellen 2 verlaufende Kreuzspulentransporteinrichtung 21 überführbar sind.The drive drum that the cheese 11 during the Drives winding process over friction, carries the Reference number 17. During the winding process, the cheese is 11 held in a coil frame 18 which is about an axis 19 is pivotally mounted. Below the coil frame 18 is also rotatable to a limited extent about the pivot axis 19 Swivel plate 20 arranged over which the finished cheese to the one behind the winding units 2 Cross-wound bobbin transport device 21 can be transferred.

Wie vorstehend bereits angedeutet, werden die Spulstellen 2 über ein Serviceaggregat, einen sogenannten Kreuzspulenwechsler 23, versorgt. Das heißt, der Kreuzspulenwechsler 23 sorgt dafür, daß Kreuzspulen 11, die einen vorbestimmten Durchmesser erreicht haben, auf die Kreuzspulentransporteinrichtung 21 ausgetragen werden und daß anschließend aus dem Leerhülsenmagazin 22 jeweils eine Leerhülse 28 in den Spulenrahmen 18 eingewechselt wird.As already indicated above, the winding units 2 via a service unit, a so-called cross-coil changer 23, supplied. That is, the package changer 23 provides ensure that cross-wound bobbins 11 which have a predetermined diameter have reached, on the bobbin transport device 21st be carried out and that subsequently from the Empty sleeve magazine 22 each have an empty sleeve 28 in the Coil frame 18 is replaced.

In Fig. 2 sind einige der im Zuge des Wechselvorganges Kreuzspule/Leerhülse benötigten Handhabungselemente des Serviceaggregates 23 dargestellt, die da sind: Rahmenöffner 29, Rahmenheber 32, Spulenführungsvorrichtung 33 sowie Hülsenzubringer 31.
Der Übersichtlichkeit halber wurde in dieser Figur auf die Darstellung weiterer Handhabungselemente derartiger Kreuzspulenwechsler verzichtet. Die Vorrichtungen zum Erstellen einer Kopfreservewicklung sowie der Fußreservewicklung sind beispielsweise nicht gezeigt.2 shows some of the handling elements of the service unit 23 required in the course of the cross-wound / empty tube change process, which are: frame opener 29, frame lifter 32, coil guide device 33 and sleeve feeder 31.
For the sake of clarity, the illustration of further handling elements of such cross-wound bobbin changers has been omitted in this figure. The devices for creating a head reserve winding and the foot reserve winding are not shown, for example.

Wie in den Figuren 1 bis 3 angedeutet, sind über den Maschinenbus 40 die Zentralsteuereinheit 37 der Textilmaschine 1, die Spulstellenrechner 39 der einzelnen Spulstellen 2 und der Steuerungsrechner 38 des Serviceaggregates 23 miteinander verbunden. As indicated in Figures 1 to 3, are about the Machine bus 40 the central control unit 37 of the Textile machine 1, the winding unit computer 39 of the individual Winding units 2 and the control computer 38 of the Service units 23 connected to each other.

Die Fig. 3 zeigt, daß der Spulstellenrechner 39 mehrere sogenannte Treiber 43 besitzt, die über Befehlsleitungen jeweils mit nachgeordneten Funktionselementen verbunden sind. Die Endstufe 44 des Fadenspanners 14 ist beispielsweise über eine Befehlsleitung 41 an einen der Treiber 43 des Spulstellenrechners 39 angeschlossen.
Der an sich bekannte und bewährte Fadenspanner 14 weist, wie üblich, eine Drehtelleranordnung 47, 48 auf. Dabei ist der Drehteller 47 durch einen Antrieb 49 rotatorisch beaufschlagbar, während der Drehteller 48 durch eine Tauchspule 45, 46 axial verschoben werden kann.
Zwischen den Drehtellern 47, 48 wird der von einem Spinnkops 9 abgezogene Faden 30, der nachfolgend zu einer Kreuzspule 11 aufgewickelt wird, definiert geklemmt. Über das Maß der Klemmung der Bremsteller des Fadenspanners ist dabei die am Faden 30 wirksame Fadenspannung einstellbar.
Das heißt, die Fadenspannung wird bei diesen bekannten Fadenspannern durch entsprechende Bestromung der Tauchspule 45, 46 eingestellt.3 shows that the winding unit computer 39 has a plurality of so-called drivers 43, which are each connected to downstream functional elements via command lines. The output stage 44 of the thread tensioner 14 is connected, for example, via a command line 41 to one of the drivers 43 of the winding station computer 39.
The known and proven thread tensioner 14 has, as usual, a turntable arrangement 47, 48. The turntable 47 can be acted upon in rotation by a drive 49, while the turntable 48 can be axially displaced by a moving coil 45, 46.
Between the turntables 47, 48, the thread 30 drawn off from a spinning cop 9, which is subsequently wound up into a cross-wound bobbin 11, is clamped in a defined manner. The thread tension effective on the thread 30 can be adjusted via the degree of clamping of the brake adjuster of the thread tensioner.
This means that the thread tension in these known thread tensioners is adjusted by energizing the moving coil 45, 46 accordingly.

Funktion der Einrichtung:Function of the facility:

Während des 'normalen' Spulprozesses wird die Fadenspannung am Faden 30 über den Fadenspanner 14 geregelt, der zu diesem Zeitpunkt vom Spulstellenrechner 39 der betreffenden Spulstelle 2 entsprechend angesteuert wird.During the 'normal' winding process the thread tension on the Thread 30 regulated by the thread tensioner 14 to this Time from the winding unit computer 39 of the winding unit concerned 2 is controlled accordingly.

Wenn an einer der Spulstellen 2 des Kreuzspulautomaten 1 eine Kreuzspule 11 ihren vorgegebenen Durchmesser oder ihre vorgegebene Fadenlänge erreicht hat, wird über die Fadenschneideinrichtung 16 zunächst der Faden 30 getrennt und die Kreuzspule durch eine (nicht dargestellte) Spulenabhebevorrichtung von der Antriebstrommel gehoben. Die Kreuzspule 11 läuft dann gebremst oder ungebremst in den Stillstand aus. If at one of the winding units 2 of the automatic winder 1 a Cheese 11 their predetermined diameter or their has reached the specified thread length, is via the Thread cutting device 16 first separated the thread 30 and the cheese through a (not shown) Coil lifting device lifted from the drive drum. The Cross-wound bobbin 11 then runs in the braked or unbraked Standstill off.

Da das Serviceaggregat 23 nur einen laufenden Faden 30 fassen kann, wird die Kreuzspule 11 anschließend wieder auf die inzwischen ebenfalls stehende Antriebstrommel 17 abgesenkt und der Faden 30 in der Spleißeinrichtung 13 der Spulstelle 2 neu verspleißt.
Gleichzeitig wird vom Spulstellenrechner 39 der Kreuzspulenwechsler 23 angefordert. Die Anforderung des Kreuzspulenwechslers kann dabei auch präventiv erfolgen, das heißt, das Anforderungssignal kann bereits abgesetzt werden bevor die Kreuzspule ihren endgültigen Durchmesser erreicht hat.Since the service unit 23 can only take one running thread 30, the package 11 is then lowered again onto the drive drum 17, which has meanwhile also become stationary, and the thread 30 is spliced anew in the splicing device 13 of the winding unit 2.
At the same time, the package changer 39 requests the bobbin changer 23. The request for the cross-wound bobbin changer can also be carried out preventively, that is to say the request signal can be issued before the cross-wound bobbin has reached its final diameter.

Das angeforderte Serviceaggregat 23 positioniert sich an der betreffenden Spulstelle und nimmt mit einem sogenannten Fadenheber zunächst den Faden 30 auf, um ihn für den nachfolgenden Wechselvorgang bereitzuhalten. Außerdem übernimmt jetzt, für die Zeit des Wechselvorganges, der Steuerungsrechner 38 des Serviceaggregates 23 über den Maschinenbus 40 die Führung des Spulstellenrechners 39 der betreffenden Spulstelle 2. Das heißt, während des Wechselvorganges erfolgt auch die Ansteuerung des Fadenspanners 14 über den Steuerungsrechner 38 des Serviceaggregates 23. Die Fadenspannungswerte, die während des Wechselvorganges durch den Fadenspanner 14 eingehalten werden, sind dabei abhängig von den jeweiligen Spulenhandhabungsmaßnahmen beziehungsweise von der gewählten Ausbildung der Kreuzspule 11.
Wenn die Kreuzspule 11 beispielsweise mit einer Topcone-Wicklung versehen wird, muß der im Fadenheber gehaltene Faden 30 mit einer anderen Fadenspannung auf die Hülsenspitze aufgewickelt werden als wenn die Kreuzspule eine Fadenendreserve in Form einer Sehne erhält.
Zum Bilden einer Topcone-Wicklung wird der im Fadenheber gehaltene Faden 30 beispielsweise durch ein entsprechendes (nicht dargestelltes) Arbeitselement in Richtung der Hülsenspitze verlegt und die Kreuzspule dabei langsam in Aufwickelrichtung gedreht. Die Fadenspannung ist dabei vorzugsweise geringfügig höher, als die Fadenspannung auf dem letzten Abschnitt der Spulenreise.
Wenn das Fadenende einer Kreuzspule 11 in Form einer Fadensehne vorliegen soll, wird der Faden im Anschluß an die Spulenreise kurz von der Mantelfläche der Kreuzspule herunter- und sofort wieder auf die Mantelfläche zurückgeführt. In diesem Fall ist es vorteilhaft, wenn mit einer deutlich verringerten Fadenspannung gearbeitet wird.
Das Verfahren zum Erstellen einer solchen Fadensehne ist dabei grundsätzlich bekannt und beispielsweise in der DE 40 40 532 C2 beschrieben.The requested service unit 23 positions itself at the winding station in question and initially picks up the thread 30 with a so-called thread lifter in order to keep it ready for the subsequent changing process. In addition, the control computer 38 of the service unit 23 now takes over the control of the winding unit computer 39 of the winding unit 2 in question for the time of the changing operation. That is, during the changing operation, the thread tensioner 14 is also controlled via the control computer 38 of the service unit 23 The thread tension values which are maintained by the thread tensioner 14 during the changing process are dependent on the respective bobbin handling measures or on the selected design of the cheese 17.
If the package 11 is provided with a top cone winding, for example, the thread 30 held in the thread lifter must be wound onto the sleeve tip with a different thread tension than if the package has a thread end reserve in the form of a tendon.
To form a top-cone winding, the thread 30 held in the thread lifter is, for example, laid in the direction of the sleeve tip by means of a corresponding working element (not shown) and the cross-wound bobbin is slowly rotated in the winding direction. The thread tension is preferably slightly higher than the thread tension on the last section of the bobbin travel.
If the end of a cross-wound bobbin 11 is to be in the form of a thread chord, the thread is briefly led off from the outer surface of the cross-wound bobbin after the bobbin travel and immediately returned to the outer surface. In this case, it is advantageous to work with a significantly reduced thread tension.
The method for creating such a string is basically known and is described, for example, in DE 40 40 532 C2.

Nach dem Aufbringen der gewünschten Reservewicklung wird der Faden 30 geschnitten, wobei der Unterfaden in einer Klemmeinrichtung des Fadenhebers fixiert bleibt.
Anschließend wird über den Rahmenöffner 29 des Serviceaggregates 23 der Spulenrahmen 18 beaufschlagt, so daß die Kreuzspule 11 auf dem Schwenkblech 20 zur Ablage kommt. Durch den Rahmenheber 32 wirg dann das Schwenkblech 20 angehoben, so daß die Kreuzspule auf die Kreuzspulentransporteinrichtung 21 rollt. Die Kreuzspule ist dabei durch eine Spulenführungseinrichtung 33 geführt.After the desired reserve winding has been applied, the thread 30 is cut, the lower thread remaining fixed in a clamping device of the thread lifter.
Then the bobbin frame 18 is acted upon via the frame opener 29 of the service unit 23, so that the cheese 11 comes to rest on the swivel plate 20. The swivel plate 20 is then lifted by the frame lifter 32, so that the cheese rolls onto the cheese transport device 21. The cheese is guided by a bobbin guide device 33.

Im nächsten Schritt wird durch den Hülsenzubringer 31 eine Leerhülse 28 aus dem spulstelleneigenen Leerhülsenmagazin 22 genommen und zwischen den geöffneten Armen des Spulenrahmens 18 positioniert. Gleichzeitig wird der im Fadenheber gehaltene Unterfaden so zwischen der Stirnseite der Leerhülse und der Hülsenaufnahme des Spulenrahmens 18 positioniert, daß er beim Schließen des Rahmens eingeklemmt wird. Das Serviceaggregat 23 sorgt anschließend mit einer (nicht dargestellten) Einrichtung dafür, daß die Leerhülse 28, wie üblich, eine Fußreservewicklung erhält. Auch während der Erstellung dieser Fußreservewicklung übernimmt der Steuerungsrechner 38 des Serviceaggregates 23 die Ansteuerung des Fadenspanners 14 und sorgt in diesem Fall dafür, daß der Faden 30 mit einer gegenüber der normalen Wickelspannung etwas erhöhten Fadenspannung auf die Leerhülse 28 aufgewickelt wird.In the next step, through the sleeve feeder 31 Empty tube 28 from the winding unit's own empty tube magazine 22 taken and between the open arms of the coil frame 18th positioned. At the same time, the one held in the thread lifter So bobbin thread between the front of the empty tube and the Positioned sleeve receptacle of the coil frame 18 that he at Closing the frame is jammed. The service unit 23 then provides with a facility (not shown) for the empty sleeve 28, as usual, a Foot reserve winding receives. Even while creating this The control computer 38 of the foot reserve winding takes over Service units 23 control of the thread tensioner 14 and in this case ensures that the thread 30 with a slightly higher than the normal winding tension Thread tension is wound on the empty tube 28.

Der Spulstellenrechner 39 der Spulstelle 2 übernimmt die Ansteuerung des Fadenspanners 14 erst dann erneut, wenn der reguläre Spulbetrieb wieder einsetzt, das heißt, wenn das Serviceaggregat 23 die Spulstelle verläßt.The winding unit computer 39 of the winding unit 2 takes over Activation of the thread tensioner 14 only when the regular winding operation resumes, that is, if that Service unit 23 leaves the winding unit.
