Abstract

The method involves rotating a cross wound spool (5) in an unwinding direction (Z) in a frictionally engaged manner for receiving threads. A spool frame (8) is controlled by a torque sensor such that an air gap (S) is temporally provided between a surface (31) of the cross-wound spool that is held in the frame and a spool drive roller (9) that rotates the cross wound spool. A suction nozzle (35) is subjected with low pressure, before the spool, rotating in the unwinding direction, is temporally removed from the spool drive roller.

Description

Die Erfindung betrifft ein Verfahren zum Betreiben von Arbeitsstellen einer Kreuzspulen herstellenden Textilmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a method for operating workstations of a cross-wound textile machine according to the preamble of claim 1.

Bekanntlich muss zur Herstellung einer Kreuzspule die betreffende Textilspule auf der Arbeitsstelle einer Textilmaschine sowohl um ihre Spulenachse rotiert, als auch der auf die Textilspule auflaufende Faden längs der Spulenachse mit relativ hoher Geschwindigkeit traversiert werden.As is known, in order to produce a cross-wound bobbin, the textile bobbin in question must be rotated on the workstation of a textile machine both about its bobbin axis and the thread running on the textile bobbin is traversed along the bobbin axis at a relatively high speed.

Der dabei entstehende Spulenkörper zeichnet sich nicht nur durch einen verhältnismäßig stabilen Aufbau, sondern auch durch ein gutes Ablaufverhalten aus.The resulting bobbin is characterized not only by a relatively stable design, but also by a good flow behavior.

Bei Kreuzspulen unterscheidet man dabei, abhängig von ihrem Wicklungsaufbau, zwischen Kreuzspulen mit so genannter "wilder Wicklung" und Kreuzspulen mit so genannter "Präzisions- bzw. Stufen-Präzisionswicklung".In the case of cross-wound bobbins, a distinction is made between cross-wound bobbins with so-called "wild winding" and cross-wound bobbins with so-called "precision or step precision winding", depending on their winding structure.

Um eine Kreuzspule mit einer Präzisions- oder einer Stufenpräzisionswicklung erzeugen zu können, ist es notwendig, die Rotation der Kreuzspule und die Traversierung des auflaufenden Fadens antriebstechnisch voneinander zu trennen. Das heißt, bei Einrichtungen zur Herstellung von Kreuzspulen mit einer Präzisions- oder einer Stufenpräzisionswicklung liegt die in einem Spulenrahmen drehbar gehalterte Kreuzspule beispielsweise reibschlüssig auf einer Spulenantriebswalze auf, die durch einen definiert ansteuerbaren Einzelantrieb beaufschlagbar ist, während das Traversieren des auflaufenden Fadens zum Beispiel mittels eines so genannten Fingerfadenführers erfolgt, der einen separaten, vorzugsweise ebenfalls definiert ansteuerbaren Antrieb aufweist.In order to be able to produce a cross-wound bobbin with a precision winding or a stepped precision winding, it is necessary to separate the rotation of the cross-wound bobbin and the traversing of the running thread in terms of drive technology. That is, in devices for producing cross-wound bobbins with a precision or a step precision winding which is rotatably supported in a creel cheese, for example, frictionally on a bobbin drive roller, which can be acted upon by a defined controllable single drive, while the traversing of the running yarn, for example by means of a so-called Fingerfadenführers takes place, which has a separate, preferably also defined controllable drive.

Derartige mit Fingerfadenführern ausgestattete und beispielsweise in der DE 198 58 548 A1 beschriebene Fadenchangiereinrichtungen haben sich in der Praxis als äußerst flexibel erwiesen, weisen jedoch den Nachteil auf, dass bei einer Spulunterbrechung stets die Gefahr besteht, dass der mit der Kreuzspule verbundene Oberfaden nicht ordnungsgemäß auf die Kreuzspule aufläuft, sondern zum Beispiel als so genannter Fallfaden neben eine der Stirnseiten der Kreuzspule bis zur Hülse fällt, gegebenenfalls um die Hülse gewunden wird und dann von der Saugdüse der Arbeitsstelle nicht mehr aufgenommen werden kann.Such equipped with finger thread guides and for example in the DE 198 58 548 A1 described Fadenchangiereinrichtungen have proven to be extremely flexible in practice, but have the disadvantage that at a Spulunterbrechung always the danger that the associated with the cheese upper thread does not run properly on the cheese, but as a so-called fall thread next to one the end faces of the cross-wound bobbin falls to the sleeve, possibly wound around the sleeve and then can no longer be absorbed by the suction nozzle of the job.

Es sind daher in der Vergangenheit bereits Vorrichtungen und Verfahren entwickelt worden, mit denen das Auftreten solcher Fallfäden im Falle einer Spulunterbrechung vermieden werden soll.Therefore, devices and methods have already been developed in the past with which the occurrence of such drop threads in the event of a winding interruption should be avoided.

In der DE 10 2004 052 564 A1 ist beispielsweise ein Verfahren beschrieben, bei dem der Antrieb eines Fingerfadenführers bei einer Spulunterbrechung durch einen Spulstellenrechner derart angesteuert wird, dass der Fadenführer sofort in eine Position verlagert wird, in der sichergestellt ist, dass der mit der Kreuzspule verbundene Oberfaden mittig auf die Oberfläche der Kreuzspule aufläuft.In the DE 10 2004 052 564 A1 For example, a method is described in which the drive of a finger thread guide is controlled during a winding interruption by a winding station computer in such a way that the thread guide is immediately shifted to a position in which it is ensured that the upper thread connected to the cross-wound bobbin is centered on the surface of the cross-wound bobbin runs.

Mit diesem bekannten Verfahren konnte zwar zuverlässig vermieden werden, dass es bei einer Spulunterbrechung zur Entstehung eines Fallfadens kommt, es hat sich allerdings herausgestellt, dass bei einem solchen mittig auf die Oberfläche der Kreuzspule aufgelaufenen Oberfaden, insbesondere wenn es sich um einen Faden mit einem relativ geringen Garndurchmesser handelt, die Gefahr besteht, dass der Faden von der Spulenantriebswalze in die Oberfläche der Kreuzspule "eingebügelt" wird.Although it was possible with this known method to reliably avoid the occurrence of a drop thread during a winding interruption, it has been found that with such an upper thread accumulated centrally on the surface of the cheese, in particular if it is a thread with a relative thread low yarn diameter, the There is a risk that the thread will be "ironed" by the bobbin drive roller into the surface of the cross-wound bobbin.

Ein solcher "eingebügelter" Oberfaden kann anschließend von der arbeitsstelleneigenen, mit Unterdruck beaufschlagbaren Saugdüse, die zur Aufnahme des Fadenendes des Oberfadens in den Bereich der Oberfläche der auf der Spulenantriebswalze aufliegenden und von dieser in Abwickelrichtung rotierten Kreuzspule geschwenkt wird, oft nur sehr schwer bzw. nicht mehr erfasst und aufgenommen werden.Such "ironed-in" upper thread can often be very difficult or difficult to move from the workstation's own suction nozzle which can be subjected to negative pressure, which is pivoted to receive the thread end of the upper thread in the region of the surface of the cheese on the reel drive roller and rotated in the unwinding. no longer recorded and recorded.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zu entwickeln, bei dem auch bei der Verarbeitung feiner Garne ein sicherer Betrieb einer Kreuzspulen herstellenden Textilmaschine, insbesondere eine sichere Fadenaufnahme durch die Saugdüse nach einer Spulunterbrechung, gewährleistet ist.Based on the aforementioned prior art, the present invention seeks to develop a method in which a safe operation of a cheese-producing textile machine, in particular a safe thread take-up by the suction nozzle after a Spulunterbrechung is guaranteed even when processing fine yarns.

Diese Aufgabe wird erfindungsgemäß durch ein Verfahren gemäß Anspruch 1 gelöst.This object is achieved by a method according to claim 1.

Vorteilhafte Ausführungsformen des erfindungsgemäßen Verfahrens sind Gegenstand der Unteransprüche.Advantageous embodiments of the method according to the invention are the subject of the subclaims.

Das erfindungsgemäße Verfahren, bei dem die Kreuzspule zur Fadenaufnahme zunächst reibschlüssig in Abwickelrichtung rotiert und anschließend der Spulenrahmen durch einen Drehmomentgeber derart angesteuert wird, das kurzzeitig zwischen der Oberfläche der im Spulenrahmen gehalterten Kreuzspule und der die Kreuzspule rotierenden Spulenantriebswalze ein Luftspalt gegeben ist, hat den Vorteil, dass auch ein Faden, der beim Auflaufen auf die Kreuzspule in die Oberfläche der Kreuzspule "eingebügelt" wurde, durch die Saugdüse wieder erfassbar wird. Das heißt, beim Rotieren der von der Spulenantriebswalze abgehobenen Kreuzspule in Abwickelrichtung stellt sich im Bereich des Luftspaltes eine Luftströmung ein, die dafür sorgt, dass sich das Fadenende des Oberfadens etwas von der Oberfläche der Kreuzspule ablöst und damit für die mit Unterdruck beaufschlagte, arbeitsstelleneigene Saugdüse aufnehmbar wird.The method according to the invention, in which the cross-wound bobbin is initially frictionally rotated in the unwinding direction and then the creel is controlled by a torque transmitter which is given an air gap for a short time between the surface of the cross-wound bobbin and the bobbin-rotating bobbin drive roller in that a thread that has been "ironed" into the surface of the cross-wound bobbin during emergence onto the cross-wound bobbin can also be detected again by the suction nozzle. That is, during rotation of the lifted from the bobbin drive roller cheek in the unwinding turns in the air gap an air flow, which ensures that the yarn end of the upper thread slightly detaches from the surface of the cheese and thus acted upon for the vacuum, workstation's own suction nozzle becomes receivable.

Wie im Anspruch 2 beschrieben, ist in vorteilhafter Ausführungsform vorgesehen, dass die Kreuzspule während des Fadenaufnahmevorganges mehrfach kurz von der Spulenantriebswalze abgehoben wird.As described in claim 2, it is provided in an advantageous embodiment that the cross-wound bobbin is lifted several times briefly from the bobbin drive roller during the thread take-up operation.

Auf diese Weise wird nicht nur sichergestellt, dass die Kreuzspule während des Fadenaufnahmevorganges zuverlässig in Abwickelrichtung rotiert wird, sondern auch gewährleistet, dass ein "eingebügeltes" Fadenende, unabhängig von seiner Lage oder von seinem Auflaufpunkt auf die Oberfläche der Kreuzspule, sicher durch die Saugdüse aufgenommen werden kann.In this way it is not only ensured that the cheese is reliably rotated in the unwinding during the thread take-up process, but also ensures that a "folded" thread end, regardless of its location or from its casserole point on the surface of the cheese, safely absorbed by the suction nozzle can be.

Wie im Anspruch 3 dargelegt, ist vorteilhaft außerdem vorgesehen, dass die Saugdüse bereits in einer Fadenaufnahmestellung positioniert und mit Unterdruck beaufschlagt ist, bevor die in Abwickelrichtung rotierende Kreuzspule kurzzeitig von der Spulenantriebswalze abgehoben wird.As set forth in claim 3, it is also advantageously provided that the suction nozzle is already positioned in a thread receiving position and acted upon by negative pressure, before the cross-wound bobbin rotating in the unwinding direction is briefly lifted off the bobbin drive roller.

Entsprechende Versuche haben gezeigt, dass ein solches frühzeitiges Zuschalten des insbesondere an der Mündung der Saugdüse relativ starken Unterdruckes das Entstehen einer Luftströmung im Luftspalt und damit den Ablösevorgang des freien Fadenendes des Oberfadens von der Oberfläche der Kreuzspule begünstigt, was sich sehr positiv auf die nachfolgende Fadenaufnahme auswirkt.Corresponding experiments have shown that such an early connection of the particularly at the mouth of the suction nozzle relatively strong negative pressure promotes the emergence of air flow in the air gap and thus the detachment process of the free yarn end of the upper thread from the surface of the cheese, which is very positive for the subsequent thread take-up effect.

Um den bei der Fadenaufnahme notwendigen Energieeinsatz in Form von Unterdruck zu minimieren, ist außerdem vorgesehen, dass eine erfolgreiche Fadenaufnahme durch eine in der Saugdüse angeordnete Sensoreinrichtung detektiert und daraufhin der Unterdruck in der Saugdüse reduziert wird (Anspr.4).In order to minimize the energy required in the thread take-up in the form of negative pressure, it is also provided that a successful thread picking detected by a arranged in the suction nozzle sensor device and then the negative pressure in the suction nozzle is reduced (Anspr.4).

Mit den vorstehend beschriebenen Verfahrensschritten wird auf einfache Weise erreicht, dass auch Fadenenden, die nach einer Spulunterbrechung in die Oberfläche der Kreuzspule "eingebügelt" wurden, für die Saugdüse wieder zuverlässig aufnehmbar werden.With the method steps described above, it is achieved in a simple manner that even thread ends which have been "ironed" into the surface of the cross-wound bobbin after a winding interruption can be reliably picked up again for the suction nozzle.

Da ein schwenkbar gelagerter Spulenrahmen mit einem Drehmomentgeber, der, wie beispielsweise in der DE 100 60 237 A1 beschrieben, mittels eines Antriebselementes definiert im Sinne "Spulenrahmen anheben oder Spulenrahmen absenken" ansteuerbar ist, ein im Zusammenhang mit den Arbeitsstellen einer Kreuzspulen herstellenden Textilmaschine übliches und bewährtes Bauteil darstellt, reduziert sich der zusätzliche Aufwand, der zur Durchführung des erfindungsgemäßen Verfahrens benötigt wird, auf eine entsprechende softwaremäßige Ergänzung des Spulstellenrechners.As a pivotally mounted creel with a torque sensor, such as in the DE 100 60 237 A1 described, by means of a drive element defined in the terms "Raise creel or lower creel" is controlled, represents a common and proven component in connection with the jobs of a cheesemaker textile machine, reduces the additional effort required to carry out the method according to the invention on a corresponding software supplement of the winding station computer.

Die Erfindung wird nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispieles näher erläutert.The invention will be explained in more detail with reference to an embodiment shown in the drawings.

Auf diesen Arbeitsstellen 2 werden, wie ebenfalls bekannt und daher nicht näher erläutert, die auf einer Ringspinnmaschine produzierten Spinnkopse 3 zu großvolumigen Kreuzspulen 5 umgespult, die nach ihrer Fertigstellung mittels eines (nicht dargestellten) Serviceaggregates, beispielsweise eines Kreuzspulenwechslers, auf eine maschinenlange Kreuzspulentransporteinrichtung 7 übergeben und zu einer maschinenendseitig angeordneten Spulenverladestation oder dergleichen transportiert werden.At these jobs 2, as also known and therefore not explained in more detail, the spinning cops produced on a ring spinning machine 3 rewound to large-volume cheeses 5, which after their completion by means of a (not shown) service unit, such as a cheese change, handed over to a machine-length cheese package conveyor 7 and transported to a machine loading side arranged Spulenverladestation or the like.

Eine dieser Einrichtungen ist beispielsweise die mit der Bezugszahl 4 gekennzeichnete Spulvorrichtung, die einen um eine Schwenkachse 12 beweglich gelagerten Spulenrahmen 8 aufweist, der, wie in Figur 4 dargestellt, durch einen insgesamt mit der Bezugszahl 60 gekennzeichneten, so genannten Drehmomentgeber definiert anhebbar bzw. absenkbar ist.One of these devices is, for example, the winding device identified by the reference numeral 4, which has a coil frame 8 movably mounted about a pivot axis 12, which, as in FIG FIG. 4 represented by a designated generally by the reference numeral 60, so-called torque sensor defined can be raised or lowered.

Während des regulären Spulprozesses liegt die Kreuzspule 5, wie in den Figuren 1 und 2 dargestellt, mit ihrer Oberfläche 31 auf einer Spulenantriebswalze 9 auf und wird von dieser über Reibschluss mitgenommen.During the regular winding process is the cheese 5, as in the FIGS. 1 and 2 shown with its surface 31 on a bobbin drive roller 9 and is carried along by this frictional engagement.

Die Spulenantriebswalze 9 ist ihrerseits an einen elektromotorischen Einzelantrieb 34 angeschlossen, der über eine Steuerleitung 19 mit dem Spulstellenrechner in Verbindung steht.The bobbin drive roller 9 is in turn connected to an electric motor single drive 34 which is connected via a control line 19 to the winding station computer in connection.

Zur Changierung des während des Spulprozesses auf die Kreuzspule auflaufenden Fadens 16 ist eine Fadenverlegeeinrichtung 10 vorgesehen.For traversing the running up during the winding process on the cross-wound yarn 16, a yarn laying device 10 is provided.

Eine solche in den Figuren lediglich schematisch angedeutete und beispielsweise aus der DE 10 2004 052 564 A1 bekannte Fadenverlegeeinrichtung 10 verfügt über einen Fingerfadenführer 13, der, durch einen elektromotorischen Antrieb 14 beaufschlagt, den Faden 16 zwischen den beiden Stirnseiten 32A und 32B der Kreuzspule 5 traversiert.Such in the figures only schematically indicated and for example from the DE 10 2004 052 564 A1 known thread laying device 10 has a finger thread guide 13, which, acted upon by an electric motor drive 14, the thread 16 traversed between the two end faces 32A and 32B of the cheese 5.

Wie insbesondere aus der Figur 4 ersichtlich, weist der Antrieb 14 eine Motorwelle 33 auf, auf der der fingerartig ausgebildete Fadenführer 13 drehfest angeordnet ist.As in particular from the FIG. 4 can be seen, the drive 14, a motor shaft 33 on which the finger-like yarn guide 13 is arranged rotationally fixed.

Auf der dem Fadenführer 13 gegenüberliegenden Seite des Antriebes 14 ist, vorzugsweise geschützt unter einer abnehmbaren Abdeckkappe, ein an sich bekannter Winkelsensor 17 montiert, dessen Aufbau in der DE 103 54 587 A1 ausführlich erläutert ist.On the opposite side of the thread guide 13 of the drive 14 is mounted, preferably protected under a removable cover, a per se known angle sensor 17, whose structure in the DE 103 54 587 A1 is explained in detail.

Der Antrieb 14 sowie der Winkelsensor 17 sind über Signal- und Steuerleitungen 15 bzw. 18 mit dem Spulstellenrechner 28 der betreffenden Arbeitsstelle 2 verbunden.The drive 14 and the angle sensor 17 are connected via signal and control lines 15 and 18 with the winding station computer 28 of the relevant job 2.

Derartige Arbeitsstellen 2 verfügen in der Regel des Weiteren jeweils über einen Unterfadensensor 40, einen Fadenreiniger 22, eine Fadenschneideinrichtung 23 sowie einen Fadenzugkraftsensor 20, wobei diese Bauteile über Steuer- und Signalleitungen 40, 29, 30 bzw. 21 an den Spulstellenrechner 28 angeschlossen sind. Jede der Arbeitsstellen 2 weist außerdem, wie üblich, eine mit Unterdruck beaufschlagbare Saugdüse 35, ein ebenfalls mit Unterdruck beaufschlagbares, so genanntes Greiferrohr 37 und eine pneumatische Fadenspleißeinrichtung 36 auf.Such workstations 2 generally further each have a lower thread sensor 40, a thread cleaner 22, a thread cutting device 23 and a yarn tension sensor 20, these components are connected via control and signal lines 40, 29, 30 and 21 to the winding station computer 28. Each of the workstations 2 also has, as usual, a suction nozzle 35 which can be acted upon by negative pressure, a so-called gripper tube 37, which can also be subjected to negative pressure, and a pneumatic thread splicing device 36.

Die Saugdüse 35 weist außerdem vorzugsweise, wie in Fig.3 angedeutet, eine Sensoreinrichtung 61 auf, die eine erfolgreiche Fadenaufnahme detektiert.The suction nozzle 35 also preferably has, as in Figure 3 indicated, a sensor device 61 which detects a successful thread take-up.

Wie in Fig.4 in perspektivischer Ansicht dargelegt, weist jede der Arbeitsstellen 2 der Kreuzspulen herstellenden Textilmaschine 1 einen schwenkbar gelagerten Spulenrahmen 8 auf, der, wie vorstehend bereits angedeutet, mittels eines an sich bekannten Drehmomentgebers 60 angehoben bzw. abgesenkt werden kann.As in Figure 4 set forth in perspective view, each of the jobs 2 of the cross-wound textile machine 1 has a pivotally mounted creel 8, which, as already indicated above, can be raised or lowered by means of a known torque sensor 60.

In dem in Figur 4 dargestellten Ausführungsbeispiel ist in einem Spulstellengehäuse 62 einer insgesamt mit 2 bezeichneten Arbeitsstelle eine Spulenantriebswalze 9 gelagert, die von einem Spulenwalzenantrieb 34 in Form eines elektromotorischen Einzelantriebes angetrieben wird.In the in FIG. 4 illustrated embodiment is designated in a winding station housing 62 a total of 2 Working a coil drive roller 9 mounted, which is driven by a spool roller drive 34 in the form of an electric motor single drive.

Die Spulenantriebswalze treibt während des regulären Spulbetriebes die Kreuzspule 5 reibschlüssig an.The bobbin drive roller drives the cross-wound bobbin 5 frictionally during the regular winding operation.

Die Kreuzspule 5 ist dabei in einem Spulenrahmen 8 gehaltert, der drehfest mit einer Schwenkachse 12 verbunden ist, die parallel zur Spulenantriebswalze 9 angeordnet und zum Beispiel über ein entsprechendes (nicht dargestelltes) Lager begrenzt schwenkbar am Spulstellengehäuse 62 gelagert ist.The cross-wound bobbin 5 is held in a creel 8, which is rotatably connected to a pivot axis 12, which is arranged parallel to the bobbin drive roller 9 and for example via a corresponding (not shown) bearing limited pivotally mounted on the winding unit housing 62.

Der Spulenrahmen 8 besitzt seinerseits, wie üblich, zwei Spulenarme, die mit drehbar gelagerten Spulentellern versehen sind, zwischen denen eine Hülse gehaltert ist, auf die der Faden 16 zur Bildung einer Kreuzspule 5 aufgespult werden kann.The bobbin frame 8 in turn has, as usual, two coil arms, which are provided with rotatably mounted bobbin plates, between which a sleeve is mounted, on which the thread 16 can be wound to form a cross-wound bobbin 5.

An der Schwenkachse 12 des Spulenrahmens 8 greift ein insgesamt mit der Bezugszahl 60 gekennzeichneter Drehmomentgeber an.On the pivot axis 12 of the coil frame 8 engages a generally designated by the reference numeral 60 torque sensor.

Der Drehmomentgeber 60 weist unter anderem eine drehfest mit der Schwenkachse 12 verbundene Anschlussscheibe 59 sowie ein koaxial zur Schwenkachse 12 angeordnetes, drehbar gelagertes Zahnrad 50 auf. Die Anschlussscheibe 59 ist mit Anschlussbolzen 51 versehen, die zum Zahnrad 50 hinweisen.The torque transmitter 60 has, inter alia, a connection disk 59, which is connected to the pivot axis 12 in a rotationally fixed manner and has a rotatably mounted gear wheel 50 arranged coaxially with the pivot axis 12. The connection plate 59 is provided with connecting bolts 51, which point to the gear 50.

Am Zahnrad 50 sind entsprechende Anschlussbolzen 52 vorgesehen. Zwischen den Anschlussbolzen 51 der Anschlussscheibe 59 und den Anschlussbolzen 52 des Zahnrades 50 sind als Übertragungselemente identische Federelemente 53, im vorliegenden Fall Schraubenfedern, eingeschaltet.On the gear 50 corresponding connecting bolts 52 are provided. Between the connecting pin 51 of the connection plate 59 and the connecting pin 52 of the gear 50 are identical transmission elements as spring elements 53, in the present case coil springs turned on.

Die Schraubenfedern 53 werden bei relativer Verdrehung von Zahnrad 50 und Anschlussscheibe 59 gegensinnig verformt.The coil springs 53 are deformed in opposite directions with relative rotation of gear 50 and connecting plate 59.

Das drehbar gelagerte Zahnrad 50 kämmt mit einem Ritzel 54 eines Untersetzungsgetriebes, dessen Außenkranz 55 über ein Antriebsritzel 56 an ein Antriebselement 57, vorzugsweise einen Schrittmotor, angeschlossen ist.The rotatably mounted gear 50 meshes with a pinion 54 of a reduction gear, the outer ring 55 via a drive pinion 56 to a drive element 57, preferably one Stepper motor, connected.

Da das Antriebsritzel 56, der Außenkranz 55 und das Ritzel 54 am Spulstellengehäuse 62 drehbar gelagert sind, kann über das Übersetzungsgetriebe jede Drehbewegung des am Spulstellengehäuse 62 festgelegten Schrittmotors 57, beispielsweise im Verhältnis 1 : 25, auf das Zahnrad 50 übertragen werden.Since the drive pinion 56, the outer ring 55 and the pinion 54 are rotatably mounted on the winding unit housing 62, can be transmitted to the gear 50 via the transmission gear each rotational movement of the set on the winding head housing 62 stepping motor 57, for example in the ratio 1:25.

Der Schrittmotor 57, der zum Beispiel für Einzelschritte von circa 1,8 Grad ausgelegt ist, wird über eine Steuerleitung 69 vom Spulstellenrechner 28 angesteuert und vermag so eine vorbestimmte Anzahl von Umdrehungen oder eine vorbestimmte Anzahl von Einzelschritten auszuführen, die mittels des Drehmomentgebers 60 am Spulenrahmen 8 ein Drehmoment, zum Beispiel Mauf, ergeben.The stepping motor 57, which is designed for individual steps of approximately 1.8 degrees, for example, is controlled by a winding line computer 69 via a control line 69 and is thus able to execute a predetermined number of revolutions or a predetermined number of individual steps which are effected by means of the torque transmitter 60 on the creel 8 gives a torque, for example M on .

Über dieses Drehmoment Mauf ist sowohl der Auflagedruck der Kreuzspule 5 auf der Spulenantriebswalze 9 definiert und feinfühlig einstellbar, als auch die Kreuzspule 5 für vorgebbare Zeitspannen von der in Abwickelrichtung rotierten Spulenantriebswalze 9 abhebbar.About this torque M on both the contact pressure of the cheese 5 on the bobbin drive roller 9 is defined and sensitively adjustable, as well as the cross-wound bobbin 5 can be lifted for predetermined periods of the unwinding in the unwinding reel drive roller 9.

Ablauf des erfindungsgemäßen Verfahrens:Procedure of the method according to the invention:

Wie in den Figuren 1 und 2 dargestellt, wird während des regulären Spulbetriebes von einem auf einem Transportteller 11 angeordneten, in einer Abspulstellung im Bereich einer der Quertransportstrecken 6 positionierten Spinnkops 3 ein Faden 16 abgewickelt und auf eine großvolumige Kreuzspule 5 aufgespult, die während des Spulprozesses drehbar zwischen den Lagerarmen eines Spulenrahmens 8 gehalten ist und während des Spulprozesses mit ihrer Oberfläche 31 auf einer Spulenantriebswalze 9 aufliegt.As in the FIGS. 1 and 2 is shown, is arranged during the regular winding operation of a arranged on a transport plate 11, in a Abspulstellung in the region of one of the transverse transport sections 6 Spinnkops 3 a yarn 16 unwound and wound on a large-volume cheese 5, the rotatable during the winding process between the bearing arms of a coil frame. 8 is held and rests with its surface 31 on a bobbin drive roller 9 during the winding process.

Die Spulenantriebswalze 9, die durch einen elektromotorischen Antrieb 34, der über eine Steuerleitung 19 mit dem Spulstellenrechner 28 verbunden ist, definiert antreibbar ist, nimmt die Kreuzspule 5 reibschlüssig mit.The bobbin drive roller 9, which is drivable by an electric motor drive 34 which is connected via a control line 19 to the winding station computer 28, takes the cross-wound bobbin 5 by friction.

Der vom Spinnkops 3 ablaufende Faden 16 durchquert auf seinem Weg zur Kreuzspule 5 unter anderem einen Unterfadensensor 40, eine Fadenschneideinrichtung 23, einen Fadenzugkraftsensor 20 sowie einen Fadenreiniger 22, der den laufenden Faden 16 auf Fadenfehler hin überwacht.The running of the spinning cop 3 thread 16 traversed on its way to the cheese 5, inter alia, a lower thread sensor 40, a thread cutting device 23, a yarn tension sensor 20 and a thread cleaner 22, which monitors the running thread 16 for thread error out.

Das heißt, der laufende Faden 16 erzeugt im Fadenreiniger 22 unter anderem ein dynamisches Fadenlaufsignal, das über die Signalleitung 29 auf den Spulstellenrechner 28 übertragen wird. Bleibt dieses dynamische Fadenlaufsignal, beispielsweise aufgrund eines Fadenbruches, aus, steuert der Spulstellenrechner 28, der über den angeschlossenen Winkelsensor 17 stets über die Momentanposition des Fingerfadenführers 13 informiert ist, über die Steuerleitung 15 den Antrieb 14 des Fingerfadenführers 13 derart an, dass der Fingerfadenführer 13 schnellstmöglich zu der Mitte der Kreuzspule 5 hin überführt wird.That is, the running thread 16 generated in the thread cleaner 22, inter alia, a dynamic yarn running signal, which is transmitted via the signal line 29 to the winding station computer 28. If this dynamic yarn running signal, for example, due to a yarn breakage, off, the winding station calculator 28, which is always informed via the connected angle sensor 17 on the instantaneous position of the finger thread guide 13, controls the drive 14 of the finger thread guide 13 via the control line 15 so that the finger thread guide 13th is transferred as soon as possible to the center of the cheese 5 out.

Das heißt, der Fingerfadenführer 13 sorgt dafür, dass der Oberfaden nach einem Fadenbruch möglichst mittig auf die Kreuzspule 5 aufläuft.That is, the finger thread guide 13 ensures that the upper thread runs after a yarn break as centrally as possible on the cheese 5.

Auch bei einem durch den Fadenreiniger 22 initiierten kontrollierten Reinigerschnitt sorgt der Spulstellenrechner 28 dafür, dass der Fingerfadenführer 13 schnellstmöglich zur der Mitte der Kreuzspule 5 hin überführt wird und der Oberfaden mittig auf die Kreuzspule 5 aufläuft.Even with a initiated by the thread cleaner 22 controlled cleaner cut the winding unit computer 28 ensures that the finger thread guide 13 is transferred as quickly as possible to the center of the cheese 5 out and the upper thread runs centrally on the cheese 5.

Zur Fortführung des Spulprozesses muss der auf die Kreuzspule 5 aufgelaufene Oberfaden in einer Fadenspleißvorrichtung 36 mit einem Unterfaden pneumatisch verwirbelt werden, der mit dem Spinnkops 3 verbunden ist und vom Greiferrohr 37 vorgelegt wird.To continue the winding process, the upper thread that has accumulated on the cross-wound bobbin 5 must be pneumatically swirled in a thread splicing device 36 with a bobbin thread, which is connected to the spinning cop 3 and presented by the gripper tube 37.

Zur Aufnahme des Fadenendes des Oberfadens wird deshalb die Saugdüse 35 zunächst in die Fadenendaufnahmeposition I geschwenkt, in der die Mündung der Saugdüse 35 unmittelbar im Bereich Oberfläche 31 der Kreuzspule 5 angeordnet ist und die Saugdüse 35 mit Unterdruck beaufschlagt.For receiving the yarn end of the upper thread, therefore, the suction nozzle 35 is first pivoted into the Fadenendaufnahmeposition I, in which the mouth of the suction nozzle 35 is disposed directly in the surface 31 of the cheese 5 and the suction nozzle 35 is subjected to negative pressure.

Anschließend wird die Kreuzspule 5 durch die Spulenantriebswalze 9 in Abwickelrichtung Z rotiert und anschließend kurzzeitig, bei Bedarf auch mehrmals nacheinander, von der Spulenantriebswalze 9 abgehoben.Subsequently, the cheese 5 is rotated by the bobbin drive roller 9 in the unwinding Z and then briefly, if necessary, several times in succession, lifted from the bobbin drive roller 9.

Durch dieses Abheben der Kreuzspule 5 entsteht zwischen der Kreuzspule 5 und der Spulenantriebswalze 9 ein Luftspalt S sowie im Luftspalt S eine Luftströmung.By this lifting of the cheese 5 is formed between the cheese 5 and the coil drive roller 9, an air gap S and in the air gap S, an air flow.

Diese Luftströmung sorgt dafür, dass das Fadenende des Oberfadens von der Oberfläche 31 der Kreuzspule 5 freikommt und von der unterdruckbeaufschlagten Saugdüse 35 aufgenommen werden kann.This air flow ensures that the thread end of the upper thread of the surface 31 of the cheese 5 is released and can be absorbed by the vacuum-loaded suction nozzle 35.

Das heißt, das aufgrund des Luftstromes im Luftspalt von der Oberfläche 31 der Kreuzspule 5 gelöste Fadenende des Oberfadens kann relativ problemlos von der Saugdüse 35 aufgenommen und zu einer Fadenspleißvorrichtung 36 überführt werden, wo das Fadenende des Oberfadens mit dem Fadenende eines Unterfadens verbunden wird, den ein spulstelleneigenes Greiferrohr 37 herangeschafft hat.That is, due to the air flow in the air gap of the surface 31 of the cheese 5 dissolved yarn end of the upper thread can be relatively easily absorbed by the suction nozzle 35 and transferred to a yarn splicing device 36, where the yarn end of the upper thread is connected to the yarn end of a lower thread, the has brought a Spulstelleneigen gripper tube 37.

Nach dem Spleißen der Fadenenden von Ober- bzw. Unterfaden wird der reguläre Spulprozess fortgesetzt.After splicing the thread ends of upper or lower thread, the regular winding process is continued.
