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.

Derartige Kreuzspulen herstellende Textilmaschinen sind durch verschiedene Schutzrechtsanmeldungen bekannt.Textile machines producing such packages are through various patent applications known.

Die DE 196 46 564 A1 oder die DE 196 50 932 A1 beschreiben beispielsweise solche als automatische Spulmaschinen ausgebildete Textilmaschinen. Diese sogenannten Kreuzspulautomaten weisen jeweils eine Vielzahl von gleichartigen, in Reihe nebeneinander angeordneten Arbeitsstellen auf. Jede Arbeitsstelle verfügt ihrerseits über eine Spuleinrichtung mit einer einzelmotorisch angetriebenen Spultrommel sowie einen Arbeitsstellenrechner.DE 196 46 564 A1 or DE 196 50 932 A1 describe for example as automatic winding machines trained textile machinery. These so-called Cross-winder machines each have a variety of similar, arranged in a row next to each other Jobs on. Each job in turn has a winding device with a single motor driven Winding drum and a job computer.

Auf den Arbeitsstellen werden Ringspinnkopse zu großvolumigen Kreuzspulen umgespult.
Die Arbeitsstellen werden dabei über ein entlang der Arbeitsstellen verfahrbares Serviceaggregat versorgt, das heißt, bei Bedarf wechselt das Serviceaggregat an der betreffenden Arbeitsstelle selbsttätig eine fertiggestellte Kreuzspule gegen eine Leerhülse aus.At the workplaces, ring spools are rewound into large-volume packages.
The work stations are supplied via a service unit that can be moved along the work stations, that is, if necessary, the service unit at the work station in question automatically exchanges a finished package for an empty tube.

Des weiteren besitzen derartige Textilmaschinen eine Zentralsteuereinheit, die über einen Maschinenbus sowohl mit den Arbeitsstellenrechnern der einzelnen Arbeitsstellen als auch mit der Steuereinrichtung des Serviceaggregates verbunden ist.Furthermore, such textile machines have one Central control unit, which has both a machine bus the job computers of the individual jobs as also connected to the control device of the service unit is.

Das Serviceaggregat, vorzugsweise ein sogenannter Kreuzspulenwechsler, weist zahlreiche Handhabungseinrichtungen zum Überführen der auf den Spuleinrichtungen der Arbeitsstellen fertiggestellten Kreuzspulen auf eine maschinenlange Kreuzspulentransporteinrichtung sowie zum anschließenden Einlegen einer Leerhülse in den Spulenrahmen auf.The service unit, preferably a so-called Cross-wound bobbin changer, has numerous handling devices to transfer the on the winding devices of the jobs finished packages on a machine length Cross-wound bobbin transport device and for subsequent Insert an empty tube into the coil frame.

Solche Kreuzspulenwechsler besitzen unter anderem, wie in der DE 195 33 833 A1 ausführlich beschrieben, einen Fadenheber, der zu Beginn des Wechselvorganges in den Fadenlauf des von der Vorlagespule zur Ablaufspule verlaufenden Fadens eingeschwenkt wird. Der Fadenheber erfaßt dabei den von einer Spultrommel, die vorzugsweise als Kehrgewindewalze ausgebildet ist, changierenden Faden. Der erfaßte Faden wird anschließend durch eine am Fadenheber angeordnete Fadenschneid- und - klemmeinrichtung in einen Unter- und einen Oberfaden zerschnitten.Such packages have, among other things, as in the DE 195 33 833 A1 described in detail, a thread lifter, the at the beginning of the change process in the thread course of the Feed bobbin swung in to the thread running out bobbin becomes. The thread lifter detects that of a winding drum, which is preferably designed as a reversing thread roller, iridescent thread. The captured thread is then through a thread cutting and - arranged on the thread lifter clamping device in a lower and an upper thread cut up.

Der Oberfaden wird anschließend, zum Beispiel als Topcone-Wicklung, auf die Hülsenspitze gewickelt, während der Unterfaden so zwischen der Hülsenaufnahme des Spulenrahmens und einer neuen Leerhülse positioniert wird, daß er beim nachfolgenden Einspannen der Leerhülse geklemmt wird. Beim Wiederanlaufen der spulstelle wird die im Spulenrahmen gehaltenen Hülse durch die Spultrommel reibschlüssig angetrieben und der (Unter)Faden durch den Fadenheber dabei so geführt, daß auf dem Hülsenfuß zunächst eine sogenannte Fuß- oder Reserve-Wicklung entsteht.
Anschließend wird der von einem Ringspinnkops ablaufende Faden in der Fadenführungsnut der Spultrommel so changiert, daß eine neue Kreuzspule entsteht, die in der Wicklungsart

wilde Wicklung" aufweist.The upper thread is then wound, for example as a top-cone winding, on the tube tip, while the lower thread is positioned between the tube holder of the bobbin frame and a new empty tube that it is clamped when the empty tube is subsequently clamped. When the winding unit is restarted, the sleeve held in the bobbin frame is driven by the winding drum in a frictional manner and the (lower) thread is guided by the thread lifter in such a way that a so-called foot or reserve winding is initially created on the tube foot.
Then the thread running from a ring spinning cop is changed in the thread guide groove of the winding drum in such a way that a new cross-wound bobbin is produced, which has the type of winding
Figure 00030001
wild winding ".

Je nach gewünschtem Spulenformat kommen an den Arbeitsstellen Spultrommeln in unterschiedlichenen Ausführungsform zum Einsatz.
Die eingesetzten Spultrommeln können beispielsweise 1,5gängig, 2gängig, 3gängige oder dergleichen sein.Depending on the desired reel format, reel drums in different designs are used at the work stations.
The winding drums used can be, for example, 1.5-speed, 2-speed, 3-speed or the like.

Nachteilig bei den bekannten Kreuzspulautomaten ist allerdings, daß bei der zu Beginn des Wechselvorganges notwendigen Fadenaufnahme die Spultrommeln stets für eine festvorgegebene Zeitspanne angetrieben werden. Diese Zeitspanne ist dabei so bemessen, daß auch bei Spultrommeln mit einer maximalen Gängigkeit noch gewährleistet ist, daß der Faden dem Fadenheber zuverlässig, in der Regel wenigstens zweimal, vorgelegt wird. Das heißt, die Zeitspanne und damit die Anzahl der Umdrehungen, die die Spultrommel während der Fadenaufnahme durchführt, ist stets gleich. Die Gängigkeit der eingesetzten Spultrommel bleibt völlig unberücksichtigt.A disadvantage of the known automatic winding machines is, however, that at the start of the change process necessary Thread take up the winding drums always for a fixed one Period are driven. This time span is so dimensioned that even with winding drums with a maximum Free movement is still ensured that the thread is the thread lifter reliably, usually at least twice. That is, the time span and therefore the number of revolutions, which the winding drum performs during thread take-up always the same. The smoothness of the winding drum used remains completely disregarded.

Ausgehend von Textilmaschinen der vorgenannten Gattung liegt der Erfindung die Aufgabe zugrunde, derartige Textilmaschinen zu verbessern.Starting from textile machines of the aforementioned type the object of the invention, such textile machines to improve.

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 einer Kreuzspulen herstellenden Textilmaschine hat den Vorteil, daß die Umdrehungen der Spultrommel während der Fadenaufnahme stets individuell auf den jeweilig eingesetzten Spultrommeltyp, inbesondere auf die Gängigkeit der Spultrommel, abgestimmt sind.
Dadurch ist einerseits sichergestellt, daß der durch die Spultrommel changierte Faden dem Fadenheber stets so vorgelegt wird, daß er durch den Fadenheber zuverlässig aufgenommen werden kann, andererseits wird mehrmaliges, überflüssiges Changieren des Fadens vermieden.
Das heißt, die für die Fadenaufnahme erforderliche Zeit kann durch die exakte Abstimmung der Spultrommelumdrehungen auf die Gängigkeit der jeweiligen Spultrommel um bis zu 60 % verkürzt werden.
Die dadurch erzielbare Verkürzung der Zykluszeit des Kreuzspulenwechsels wirkt sich insgesamt positiv aus, da die Verfügbarkeit des Serviceaggregates erhöht und damit der Wirkungsgrad der Textilmaschine gesteigert wird.The design of a textile machine producing cross-wound bobbins according to the invention has the advantage that the turns of the winding drum during thread take-up are always individually matched to the type of winding drum used in each case, in particular to the smooth running of the winding drum.
This ensures, on the one hand, that the thread that has been changed by the winding drum is always presented to the thread lifter in such a way that it can be reliably picked up by the thread lifter, on the other hand, repeated, unnecessary traversing of the thread is avoided.
This means that the time required for thread take-up can be reduced by up to 60% by precisely coordinating the number of revolutions of the winding drum to the smooth running of the respective winding drum.
The shortening of the cycle time of the package change that can be achieved in this way has an overall positive effect, since the availability of the service unit is increased and the efficiency of the textile machine is increased.

In einer bevorzugten, im Anspruch 2 beschriebenen Ausführungsform, sind die Daten über die Gängigkeit der eingesetzten Spultrommeln in der Zentralsteuereinheit der Textilmaschine abgelegt.
Da die Zentralsteuereinheit über einen Maschinenbus sowohl mit den einzelnen Arbeitsstellenrechnern als auch mit der Steuereinrichtung des Serviceaggregates verbunden ist, sind die Spultrommeldaten stets verfügbar, bzw. auf bereits zu Beginn des Partieanlaufes auf die betreffenden Steuereinrichtung überspielbar. Zusätzliche Hartware wird dabei nicht erforderlich.In a preferred embodiment described in claim 2, the data on the smoothness of the winding drums used are stored in the central control unit of the textile machine.
Since the central control unit is connected via a machine bus both to the individual workstation computers and to the control device of the service unit, the winding drum data is always available or can be transferred to the control device concerned at the start of the batch. Additional hardware is not required.

Die Ansteuerung des elektromotorischen Einzelantriebes der Spultrommel in Abhängigkeit der vorzugsweise in der Zentralsteuereinheit hinterlegten Spultrommeldaten erfolgt entweder, wie im Anspruch 4 ausgeführt, über den Arbeitsstellenrechner der betreffenden Spulstelle oder, wie im Anspruch 5 dargelegt, über die Steuereinrichtung des an der betreffenden Spulstelle positionierten Serviceaggregates.The control of the electric motor single drive Winding drum depending on the preferably in the Central control unit stored reel data either, as stated in claim 4, via the Job computer of the winding unit concerned or, as in Claim 5 set out on the control device of the at service unit positioned in the relevant winding unit.

Da die Zentralsteuereinheit der Textilmaschine, wie vorstehend bereits erwähnt, über den Maschinenbus sowohl mit den Arbeitsstellenrechnern der einzelnen Spulstellen als auch mit der Steuereinrichtung des Serviceaggregates verbunden ist, ist jederzeit problemlos eine Übertragung der in der Zentralsteuereinheit gespeicherten Spultrommeldaten auf diese elektronischen Steuerungelemente möglich.As the central control unit of the textile machine, as above already mentioned, via the machine bus with both Workstation computers of the individual winding units as well is connected to the control device of the service unit anytime a transfer of the in the Central control unit stored reel data on this electronic control elements possible.

Die Ansteuerung des elektromotorischen Einzelantriebes der Spultrommel in Abhängigkeit von der Gängigkeit der Spultrommel kann daher wahlweise sowohl durch den Arbeitsstellenrechner der betreffenden Spulstelle als auch durch die Steuereinrichtung des vor der Spulstelle positionierten Serviceaggregates erfolgen.The control of the electric motor single drive Winding drum depending on the smooth running of the winding drum can therefore either by the workstation computer relevant winding unit as well as by the control device of the service unit positioned in front of the winding unit respectively.

The finished cross-wound bobbins 11 are rolled out on a cross-wound bobbin transport device 21 by means of an automatically operating service unit, for example by means of a cross-wound bobbin changer 23, and conveyed to a bobbin loading station or the like (not shown) arranged on the machine end.

Derartige Kreuzspulautomaten 1 weisen in der Regel, insbesondere wenn sie im Verbund mit einer oder mehreren Ringspinnmaschinen stehen, eine Logistikeinrichtung in Form eines Spulen- und Hülsentransportsystems 3 auf. In diesem Spulen- und Hülsentransportsystem 3 laufen, auf Transporttellern 8, Spinnkopse 9 sowie Leerhülsen 34 um.Such automatic winder 1 usually have especially when combined with one or more Ring spinning machines are in the form of a logistics facility a coil and tube transport system 3. In this Coil and tube transport system 3 run on Transport plates 8, 9 spinning heads and empty tubes 34 um.

Des weiteren verfügen solche Kreuzspulautomaten 1 über eine Zentralsteuereinheit 37, die über einen Maschinenbus 40 sowohl mit den Arbeitsstellenrechnern 39 der einzelnen Spulstellen 2 als auch mit der Steuereinrichtung 38 eines die Spulstellen 2 selbsttätig versorgenden Serviceaggregates 23 verbunden ist.Furthermore, such cross winding machines 1 have one Central control unit 37, both via a machine bus 40 with the workstation computers 39 of the individual winding units 2 and with the control device 38 one of the winding units 2 automatically supplying service unit 23 is connected.

Wie aus den Figuren 2 und 3 ersichtlich, ist das Serviceaggregat 23 mit Fahrwerken 24, 25 auf maschinenlangen Laufbahnen 25, 27, die oberhalb der Spulstellen 2 angeordnet sind, verfahrbar gelagert. Das Serviceaggregat 23 sorgt dabei nicht nur dafür, daß die auf den Spulstellen 2 fertiggestellten Kreuzspulen 11 auf die Kreuzspulentransporteinrichtung 21 ausgerollt werden, sondern wechselt auch jeweils selbsttätig eine Leerhülse 28 in den Spulenrahmen 18 der betreffenden Spulstelle 2 ein. Die entsprechende Leerhülse 28 entnimmt das Serviceaggregat 23 dabei vorzugsweise einem spulstelleneigenen Leerhülsenmagazin 22.As can be seen from FIGS. 2 and 3, this is Service unit 23 with trolleys 24, 25 on machine-long Raceways 25, 27 arranged above the winding units 2 are movably supported. The service unit 23 ensures this not only that the finished on the winding units 2 Cross-wound bobbins 11 on the cross-wound bobbin transport device 21 are rolled out, but also changes automatically an empty sleeve 28 in the coil frame 18 of the concerned Winding unit 2. The corresponding empty sleeve 28 takes this Service unit 23 preferably a winding unit own Empty sleeve magazine 22.

Wie vorstehend bereits angedeutet, verfügen derartige Textilmaschinen über ein Spulen- und Hülsentransportsystem 3. Von diesem umfangreichen Transportsystem 3 sind in den Figuren 2 und 3 lediglich die maschinenlange Transportstrecke 4, die hinter den Spulstellen 2 verlaufende, reversierende Kopszuführstrecke 5, eine der zu den Spulstellen 2 führenden Quertransportstrecken 6 sowie die Leerhülsenrückführstrecke 7 dargestellt. As already indicated above, such Textile machines via a bobbin and tube transport system 3. Of this extensive transport system 3 are in the Figures 2 and 3 only the machine length Transport path 4, the running behind the winding units 2, reversing Kopszuführstrecke 5, one of the to Winding units 2 leading transverse transport routes 6 and the Empty sleeve return path 7 shown.

Die Spinnkopse 9 werden in den Abspulstellungen 10, die sich im Bereich der Quertransportstrecken 6 befinden, abgespult und auf der Spuleinrichtung der betreffenden Arbeitsstelle 2 zu einer großvolumigen Kreuzspulen 11 aufgewickelt.
Die einzelnen Spulstellen 2 verfügen dazu, wie bekannt und daher nur angedeutet, über verschiedene Einrichtungen, die einen ordnungsgemäßen Betrieb derartiger Arbeitsstellen 2 gewährleisten.The spinning bobbins 9 are unwound in the unwinding positions 10, which are located in the region of the transverse transport sections 6, and wound up on the winding device of the relevant work station 2 to form a large-volume cross-wound bobbin 11.
For this purpose, the individual winding units 2, as is known and therefore only indicated, have various devices which ensure the proper operation of such work stations 2.

In den Figuren 2 und 3 ist mit 30 der von einem Spinnkops 9 zu einer Kreuzspule 11 laufende Faden, mit 12 eine Saugdüse, mit 42 ein Greiferrohr, mit 13 eine Spleißeinrichtung, mit 14 eine Fadenspanneinrichtung, mit 15 ein Fadenreiniger mit Fadenschneideinrichtung sowie mit 16 eine Paraffiniereinrichtung angedeutet.In FIGS. 2 and 3, 30 is that of a spinning cop 9 a cheese 11 running thread, with 12 a suction nozzle, with 42 a gripper tube, 13 a splicing device, 14 a Thread tensioning device, with 15 a thread cleaner with Thread cutting device as well as 16 one Paraffinizing device indicated.

Die, wie in Fig.4a angedeutet, über einen elektromotorischen Einzelantrieb 50 angetriebene Spultrommel 17 beaufschlagt die Kreuzspule 11, die während des Spulvorganges in einem Spulenrahmen 18 gehalten ist, über Reibschluß.
Der Spulenrahmen 18 ist, wie üblich, um eine Achse 19 schwenkbar gelagert. Unterhalb des Spulenrahmens 18 befindet sich, ebenfalls um die Schwenkachse 19 begrenzt drehbar, ein Schwenkblech 20, über das die fertige Kreuzspule 11 auf die hinter den Spulstellen 2 verlaufende Kreuzspulentransporteinrichtung 21 überführbar ist.As indicated in FIG. 4 a, the winding drum 17, which is driven by an electromotive individual drive 50, acts on the cross-wound bobbin 11, which is held in a bobbin frame 18 during the winding process, via frictional engagement.
The coil frame 18 is, as usual, pivotally mounted about an axis 19. Below the bobbin frame 18 there is a pivot plate 20, which can also be rotated to a limited extent about the pivot axis 19, via which the finished cross-wound bobbin 11 can be transferred to the cross-wound bobbin transport device 21 running behind the bobbins 2.

Die Spulstellen 2 werden 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. Anschließend wechselt das Serviceaggregat 23 aus dem Leerhülsenmagazin 22 eine Leerhülse 28 in den Spulenrahmen 18 ein.The winding units 2 are a service unit, one so-called cross-coil changer 23 supplied. That is, the Cross-coil changer 23 ensures that cross-wound bobbins 11, the have reached a predetermined diameter on the Cross-coil transport device 21 are carried out. The service unit 23 then changes from the Empty sleeve magazine 22 an empty sleeve 28 in the coil frame 18th on.

In den Figuren 2 und 3 sind einige der im Zuge des Wechselvorganges Kreuzspule/Leerhülse benötigten Handhabungselemente des Serviceaggregates 23 dargestellt. Die wichtigsten Handhabungselemente sind dabei der Rahmenöffner 29, der Rahmenheber 32, die Spulenführungsvorrichtung 33, der Hülsenzubringer 31 sowie der Fadenheber 41.In Figures 2 and 3 are some of the in the course of Exchange process cheese / empty tube needed Handling elements of the service unit 23 shown. The most important handling elements are Frame opener 29, the frame lifter 32, the Coil guide device 33, the sleeve feeder 31 and the Thread lifter 41.

Am Fadenheber 41 ist endseitig ein Fadenfangblech 43 angeordnet, dessen Fadenfangkonturen nach beiden Seiten trichterartig geöffnet sind.
Unterhalb des Fadenfangbleches 43 befindet sich eine Klemmschere 44, das heißt, eine Fadenschere mit einer vorgeschalteten Fadenklemme. Die Klemmschere 44 ist, vorzugsweise über einen (nicht dargestellten) Pneumatikzylinder, definiert ansteuerbar.
Im Bereich einer Schwenkachse 47 des Fadenhebers 41 ist außerdem ein Fadenführungsblech 45 angeordnet.On the thread lifter 41, a thread catching plate 43 is arranged at the end, the thread catching contours of which are open in a funnel-like manner on both sides.
Below the thread catcher 43 there is a clamping scissors 44, that is, a thread scissors with an upstream thread clamp. The clamping scissors 44 can be controlled in a defined manner, preferably via a pneumatic cylinder (not shown).
A thread guide plate 45 is also arranged in the region of a pivot axis 47 of the thread lifter 41.

Die Figuren 4a bis 4c zeigen verschiedene Ausführungsformen von Spultrommeln, wie sie an den Spulstellen 2 von Kreuzspulen herstellenden Textilmaschinen zum Einsatz kommen können.Figures 4a to 4c show different embodiments of Winding drums, as they are at the winding positions 2 of packages manufacturing textile machines can be used.

Die Fig. 4a zeigt beispielsweise eine sogenannte 2gängige Spultrommel 17. Die Spultrommel 17 wird dabei über einen elektromotorischen Einzelantrieb 50 beaufschlagt. Derartige Elektro-Antriebe sind bekannt und zum Beispiel in der DE 43 36 312 A1 ausführlich beschrieben. 4a shows a so-called 2-course, for example Winding drum 17. The winding drum 17 is over a electromotive single drive 50 is applied. Such Electric drives are known and for example in the DE 43 36 312 A1 described in detail.

Die Spultrommel 17 weist, wie üblich, eine Fadenführungsnut 51 auf, die so in den Trommelkörper eingearbeitet ist, daß der in der Fadenführungsnut 51 geführte Faden nach zwei Trommelumdrehungen von einer Trommelseite zur anderen Trommelseite verlegt ist.As usual, the winding drum 17 has a thread guide groove 51 on, which is incorporated into the drum body so that the in the thread guide groove 51 guided thread after two Drum revolutions from one drum side to the other Drum side is misplaced.

Bei der in Fig. 4b dargestellten 1,5gängigen Spultrommel 17 sind entsprechend eineinhalb Trommelumdrehungen notwendig, um den in der Fadenführungsnut 51 geführten Faden von der einen Trommelseite zur anderen Trommelseite zu verlegen.
Die 3gängige Spultrommel 17 gemäß Fig. 4c erfordert entsprechend drei Trommelumdrehungen für eine Fadenverlegung.In the 1.5-speed winding drum 17 shown in FIG. 4b, one and a half drum rotations are correspondingly necessary in order to move the thread guided in the thread guide groove 51 from one drum side to the other drum side.
The 3-speed winding drum 17 according to FIG. 4c accordingly requires three drum revolutions for thread laying.

Funktion der Einrichtung:Function of the facility:

Wenn an einer der Arbeitsstellen 2 der Kreuzspulen herstellenden Textilmaschine 1 ein Bedienbedarf besteht, weil eine Kreuzspule 11 ihren vorbestimmten maximalen Durchmesser erreicht hat, verständigt der Arbeitsstellenrechner 39 der betreffenden Spulstelle 2 über den Maschinenbus 40 die Steuereinrichtung 38 des Serviceaggregates 23, das daraufhin zu der betreffenden Arbeitsstelle 2 läuft und sich dort verrastet. Gleichzeitig werden über den Maschinenbus 40 dem Arbeitsstellenrechner 39 der betreffenden Spulstelle 2 oder, je nach Antriebskonzept, der Steuereinrichtung 38 des Serviceaggregates 23 von der Zentralsteuereinheit 37 der Textilmaschine 1 die spezifischen Spultrommeldaten x, y übermittelt.
In alternativer Ausführungsform ist es selbstverständlich auch möglich, daß die Spultrommeldaten x, y bereits zu Beginn des Partieanlaufes über den Maschinenbus 40 an die betreffende Steuereinrichtung 39 oder 39 übermittelt und dort gespeichert werden.If there is a need for operation at one of the work stations 2 of the textile machine 1 producing cross-wound bobbins because a cross-wound bobbin 11 has reached its predetermined maximum diameter, the work station computer 39 of the relevant bobbin winder 2 notifies the control device 38 of the service unit 23 via the machine bus 40, which then relates to the relevant one Job 2 runs and locks in there. At the same time, the specific winding drum data x, y are transmitted via the machine bus 40 to the work station computer 39 of the winding unit 2 concerned or, depending on the drive concept, to the control device 38 of the service unit 23 by the central control unit 37 of the textile machine 1.
In an alternative embodiment, it is of course also possible for the winding drum data x, y to be transmitted via the machine bus 40 to the relevant control device 39 or 39 at the beginning of the start of the batch and stored there.

Zu Beginn des Wechselvorganges schwenkt der vor der Spulstelle 2 positionierte Kreuzspulenwechsler 23 zunächst seinen Fadenheber 41 aus der in Fig. 2 angedeuteten Ruhestellung" in die in Fig. 3 dargestellte Fadenaufnahmestellung".
In der Fadenaufnahmestellung ist das endseitig am Fadenheber 41 angeordnete Fadenfangblech 43 im Changierbereich des durch die Spultrommel 17 seitlich verlagerbaren Fadens 30 positioniert.At the beginning of the changing process, the package changer 23 positioned in front of the winding unit 2 first pivots its thread lifter 41 from that indicated in FIG. 2 Rest position "in that shown in Fig. 3 Thread take-up position ".
In the thread take-up position, the thread catch plate 43 arranged on the end of the thread lifter 41 is positioned in the traversing area of the thread 30 that can be laterally displaced by the winding drum 17.

Daraufhin wird der elektromotorische Einzelantrieb 50 der Spultrommel 17 der betreffenden Spulstelle 2 durch die Steuereinrichtung 38 des Serviceaggregates 23 oder den Arbeitsstellenrechner 39 der betreffenden Arbeitsstelle 2 derart angesteuert, daß die Anzahl der Umdrehungen, die die Spultrommel 17 während der Fadenaufnahme ausführt, exakt auf die Gängigkeit der jeweils eingesetzten Spultrommel abgestimmt ist.Thereupon the individual electric motor drive 50 becomes the Reel drum 17 of the winding unit 2 concerned by the Control device 38 of the service unit 23 or the Job computer 39 of the job in question 2 controlled so that the number of revolutions that the Spool drum 17 executes exactly during the thread take-up matched the movement of the winding drum used in each case is.

In einer alternativen Ausführungsform ist es auch denkbar, daß der Antrieb von Kreuzspule und Spultrommel über einen am Serviceaggregat angeordneten Hilfsantrieb erfolgt. Das heißt, ein definiert antreibbares Reibrad wird, wie an sich bekannt, an die Kreuzspulenoberfläche angelegt und rotiert die Kreuzspule sowie über Reibschluß die Spultrommel. Die Kreuzspule wird dabei so beaufschlagt, daß die Anzahl der Umdrehungen der Spultrommel auf der Gängigkeit abgestimmt ist.In an alternative embodiment, it is also conceivable that the drive of the bobbin and winding drum via an am Service unit arranged auxiliary drive takes place. This means, a friction wheel that can be driven in a defined manner, as is known per se, applied to the surface of the package and rotates the Cross-wound bobbin and the winding drum via friction locking. The Cross-wound bobbin is applied so that the number of Revolutions of the winding drum is matched to the smoothness.

Der durch die Spultrommel 17 changierte Faden 30 wird sicher in den Fadenfangkonturen des Fadenfangbleches 43 gefangen und der Fadenheber 41 anschließend wieder in seine Ruhestellung (Fig. 2) zurückgeschwenkt. Der Faden 30 wird dabei, durch das Fadenführungsblech 45 fixiert, in die Klemmschere 44 eingefädelt.The thread 30, which is oscillated by the winding drum 17, is securely in caught the thread catching contours of the thread catching plate 43 and the Thread lifter 41 then again in his Rest position (Fig. 2) pivoted back. The thread 30 will thereby, fixed by the thread guide plate 45, in the Clamping scissors 44 threaded.

Durch den Fadenheber wird der Faden anschließend zunächst als Kopfreserve auf die Hülsenspitze der Kreuzspule 11 aufgewickelt und dann durch die Klemmschere 40 in einen Ober- und einen Unterfaden getrennt.
Im Anschluß wird die Kreuzspule, wie üblich, durch entsprechende Handhabungseinrichtungendes Serviceaggregates auf eine maschinenlange Transportvorrichtung ausgetragen.
Der Unterfaden bleibt dabei vorübergehend in der Klemmschere 44 festgelegt.
Das heißt, der Unterfaden wird nach dem Ausstoßen der Kreuzspule an eine neu eingewechselte Leerhülse angelegt und als Fußreserve auf den Hülsenfuß aufgewickelt.
Der genaue Verfahrensablauf eines solchen Kreuzspulen/Leerhülsenwechsels, insbesondere unter Verwendung des vorbeschriebenen Fadenhebers ist an sich bekannt und beispielsweise in der DE 195 33 933 A1 relativ ausführlich beschrieben.The thread lifter then winds the thread first as a reserve head on the sleeve tip of the package 11 and then separates it into an upper and a lower thread by the clamping scissors 40.
The bobbin is then, as usual, discharged onto a machine-long transport device by appropriate handling devices of the service unit.
The lower thread remains temporarily fixed in the clamping scissors 44.
This means that after the bobbin has been ejected, the lower thread is placed on a newly inserted empty tube and wound up on the tube foot as a foot reserve.
The exact process sequence of such a bobbin / empty tube change, in particular using the thread lifter described above, is known per se and is described in relatively detail, for example, in DE 195 33 933 A1.
