Description

Die Erfindung betrifft ein Verfahren zur Bildstörung beim Aufwickeln eines Fadens auf eine Kreuzspule in wilder Wicklung, wobei die Changierfrequenz kontinuierlich zwischen einem Minimal- und einem Maximalwert geändert wird, und die Changierfrequenz bei Annäherung an ein vorgegebenes kritisches Windungsverhältnis, so geändert wird, dass sich der kurzzeitige Mittelwert der Changierfrequenz sprunghaft ändert. Ferner betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens mit einem Antrieb zum Antreiben der Kreuzspule und einem davon unabhängigen Antrieb mit einer Steuereinheit für die Changierung des Fadens.The invention relates to a method for image disturbance in winding a yarn on a cheese in wild winding, wherein the traversing frequency is continuously changed between a minimum and a maximum value, and the traversing frequency is approaching a predetermined critical turns ratio, changed so that the short-term mean value of the oscillation frequency changes abruptly. Furthermore, the invention relates to an apparatus for carrying out the method with a drive for driving the cheese and a drive independent thereof with a control unit for traversing the thread.

Beim Wickeln von Kreuzspulen unterscheidet man grundsätzlich zwischen zwei Wicklungsarten. Das ist zum einen die Präzisionswicklung und zum anderen die wilde Wicklung.When winding cross-wound bobbins, a distinction is basically made between two types of winding. On the one hand this is the precision winding and on the other hand the wild winding.

Bei der Präzisionswicklung besteht während der gesamten Spulenreise zwischen der Spulendrehzahl und der Geschwindigkeit der Fadenchangierung beziehungsweise der Changierfrequenz ein konstantes Verhältnis, so dass das Windungsverhältnis während des gesamten Spulvorganges gleich bleibt. Der Fadenkreuzungswinkel nimmt jedoch bei zunehmendem Spulendurchmesser ab. Bei der Präzisionswicklung treten keine Bildzonen auf. Die Spule weist eine hohe Wicklungsdichte auf und hat gute Ablaufeigenschaften, wodurch hohe Abzugsgeschwindigkeiten erreichbar sind.
Bedingt durch den immer kleiner werdenden Fadenkreuzungswinkel bei wachsendem Spulendurchmesser ist die Stabilität desIn precision winding, there is a constant ratio between the reel speed and the speed of the threading or traversing frequency during the entire reel travel, so that the turns ratio remains the same throughout the reeling process. However, the cross-hair angle decreases with increasing coil diameter. In precision winding, no image zones occur. The coil has a high winding density and has good drainage properties, whereby high take-off speeds can be achieved.
Due to the ever decreasing crosshairs angle with increasing coil diameter, the stability of the

Garnkörpers dagegen eingeschränkt. Zudem verursacht der abnehmende Fadenkreuzungswinkel eine Zunahme der Wickeldichte nach außen hin, was in der Färberei zu einer ungleichmäßigen Durchdringung der Färbeflotte führen kann.In contrast, the package is restricted. In addition, the decreasing crosshair angle causes an increase in the winding density to the outside, which in the dyeing can lead to uneven penetration of the dyeing liquor.

Bei der wilden Wicklung besteht während der gesamten Spulenreise ein festes Verhältnis zwischen der Spulenoberflächengeschwindigkeit und der Changierfrequenz. Hierdurch wird der Fadenkreuzungswinkel konstant gehalten, während das Windungsverhältnis, das heißt, die Anzahl der Spulenumdrehungen pro Doppelhub, bei zunehmendem Durchmesser kleiner wird. Die Vorteile der wilden Wicklung liegen darin, dass relativ stabile Garnkörper erzeugt werden können, die eine sehr gleichmäßige Dichte aufweisen.In the wild winding, there is a fixed relationship between the bobbin surface speed and the traversing frequency throughout the bobbin travel. As a result, the crosshair angle is kept constant, while the turns ratio, that is, the number of coil revolutions per double stroke, becomes smaller as the diameter increases. The advantages of the wild winding are that relatively stable packages can be produced which have a very uniform density.

Nachteilig bei dieser Wicklungsart ist allerdings, dass das Windungsverhältnis hyperbolisch abnimmt und in bestimmten Windungsverhältnisbereichen, in denen das Windungsverhältnis zum Beispiel einen ganzzahligen Wert annimmt, so genannte Bilder oder Spiegel entstehen. In diesen so genannten Bildwickelzonen liegen die Fäden in mehreren aufeinander folgenden Windungsschichten übereinander oder sehr dicht nebeneinander. Die Bilder führen dazu, dass die Kreuzspule in diesem Bereich höher verdichtet ist, so dass beispielsweise beim Färben eine ungleichmäßige Färbung entstehen kann.
Außerdem besteht die Gefahr, dass die aufeinander- oder dicht nebeneinander liegenden Fadenbereiche seitlich aufeinander abrutschen und sich dabei gegenseitig verklemmen, was sich sehr nachteilig auf die Ablaufeigenschaften einer Kreuzspule auswirkt.A disadvantage of this type of winding, however, is that the winding ratio decreases hyperbolic and, in certain winding ratio ranges, in which the turns ratio assumes, for example, an integer value, so-called images or mirrors are produced. In these so-called Bildwickelzonen the threads lie in successive layers of turns one above the other or very close together. The images cause the cross-wound bobbin to be compressed higher in this area so that, for example, dyeing may result in uneven dyeing.
In addition, there is a risk that the successive or closely adjacent thread regions laterally slip on each other and thereby jamming each other, which has a very adverse effect on the flow characteristics of a cheese.

In der Vergangenheit sind daher bereits zahlreiche Vorrichtungen und Verfahren entwickelt worden, die das Entstehen der vorbeschriebenen Bildwickelzonen verhindern sollen. Maßnahmen zur Vermeidung oder Reduzierung von Bildern bezeichnet man als Bildstörung.In the past, therefore, numerous devices and methods have already been developed which prevent the emergence of the to prevent above-described image wrapping zones. Measures for avoiding or reducing pictures are called picture disturbances.

Zur Erzeugung einer Bildstörung muss man dafür sorgen, dass die Kreuzspule Zonen mit kritischen Windungsverhältnissen möglichst schnell durchläuft. Entsprechend der Definition des Windungsverhältnisses ist dies über zwei Einstellparameter möglich. Zum einen kann die Spulendrehzahl anpasst werden und zum anderen die Changierfrequenz.To generate a picture disturbance, it is necessary to ensure that the cross-wound bobbin passes through zones with critical winding conditions as quickly as possible. According to the definition of the turns ratio, this is possible via two setting parameters. On the one hand, the coil speed can be adjusted and on the other the traversing frequency.

Wenn die Kreuzspule mittels einer Nutentrommel angetrieben wird, die gleichzeitig die Führung des Fadens übernimmt, muss ein Schlupf zwischen der Antriebstrommel und der Spule erzeugt, um das Windungsverhältnis zu beeinflussen. Dazu gibt es verschiedene Möglichkeiten.When the cross-wound bobbin is driven by means of a grooved drum which at the same time takes over the guidance of the thread, a slip must be generated between the drive drum and the bobbin in order to influence the turns ratio. For that there are different possibilities.

In der DE 195 19 542 A1 ist eine Spulmaschine zum Wickeln von Kreuzspulen offenbart, bei der die Kreuzspulen mittels Antriebstrommeln, in denen Kehrgewinderillen für die Fadenführung vorgesehen sind, angetrieben werden. Zur Vermeidung von Bildwicklungen wird die Antriebstrommel kontinuierlich mit einem konstanten vorwählbaren Moment beschleunigt und mit einem anderen konstanten vorwählbaren Moment wieder abgebremst.In the DE 195 19 542 A1 discloses a winding machine for winding cheeses, in which the cheeses are driven by means of drive drums in which Kehrgewinderillen be provided for the thread guide. To avoid image windings, the drive drum is accelerated continuously with a constant preselectable torque and decelerated again with another constant pre-selectable torque.

Die DE 198 29 597 beschreibt, im Gegensatz dazu, eine andere Möglichkeit zur Vermeidung von Bildwickeln, bei der die Spulendrehzahl nicht kontinuierlich verändert wird, sondern die Winkelgeschwindigkeit der Kreuzspule nur innerhalb der Bildwickelzone geregelt wird. Dazu wird beim oder kurz vor dem Erreichen einer Bildwickelzone die durch den Durchmesser der Kreuzspule vorgegebene Winkelgeschwindigkeit durch definiertes Einstellen des Auflagedruckes, mit dem die Kreuzspule auf der Fadenführungstrommel aufliegt, auf eine Winkelgeschwindigkeit abgesenkt, die unter der kritischen Winkelgeschwindigkeit der Bildwickelzone liegt.The DE 198 29 597 describes, in contrast, another possibility for avoiding image winding, in which the reel speed is not changed continuously, but the angular speed of the cross-wound bobbin is controlled only within the image winding zone. For this purpose, during or shortly before reaching an image winding zone, the predetermined by the diameter of the cheese angular velocity by defined setting of the contact pressure with which the cheese on the Thread guide drum rests, lowered to an angular velocity which is below the critical angular velocity of the image winding zone.

Durch die zuvor beschriebenen Verfahren tritt immer ein Schlupf zwischen der Antriebstrommel und der Kreuzspule auf. Dadurch wird zwar die gewünschte Bildstörung erreicht, aber es wird auch die Kreuzspule beziehungsweise das auf ihr gewickelte Garn negativ beeinflusst.By the methods described above, there is always a slip between the drive drum and the cross-wound bobbin. As a result, although the desired image disturbance is achieved, but it is also affected the cross-wound bobbin or the yarn wound on her negative.

Dieses Problem tritt nicht auf, wenn man die Bildstörung mittels Änderung der Changierfrequenz bewirkt und die Spulenoberflächengeschwindigkeit im Wesentlichen konstant bleibt. Dazu ist ein unabhängiger Antrieb für die Changierung erforderlich.This problem does not occur if the image disturbance is caused by changing the traversing frequency and the coil surface speed remains substantially constant. This requires an independent drive for traversing.

Auch bei der Anpassung der Changierfrequenz zur Bildstörung gibt es prinzipiell zwei Ansätze. Eine Möglichkeit zeigt die DE 43 37 891 A1 . Dabei wird die Changierfrequenz kontinuierlich zwischen einem Minimalwert und einem Maximalwert verändert. Der so entstehende zeitliche Verlauf wird als Wobbelkurve bezeichnet. Die Änderung kann periodisch oder nicht-periodisch sein. Wie in der zitierten Schrift dargestellt, können zur Herstellung einer nicht periodischen Wobbelkurve die Maximal- und die Minimalwerte zufällig verändert werden.There are also two approaches to adapting the traversing frequency to the image disturbance. One way shows that DE 43 37 891 A1 , The traversing frequency is continuously changed between a minimum value and a maximum value. The resulting time course is referred to as a wobble curve. The change can be periodic or non-periodic. As shown in the cited document, in order to produce a non-periodic sweep curve, the maximum and minimum values can be changed at random.

Aus der DE 10 2005 054 356 A1 ist es weiterhin bekannt, die hinsichtlich der Entstehung von Bildwicklungen besonders kritischen Durchmesser der Kreuzspule zu ermitteln und jeweils kurz vor Erreichen eines dieser kritischen Durchmesser den Kreuzungswinkel auf einen Wert zu ändern, der das Entstehen von Bildwicklungen in diesem Durchmesserbreich ausschließt. Nach Überfahren des kritischen Durchmesserbreichs wird der Kreuzungswinkel wieder auf seinen ursprünglichen Bereich zurückgestellt. Zur Änderung des Kreuzungswinkels wird dabei bevorzugt die Geschwindigkeit des Changierfadenführers geändert.From the DE 10 2005 054 356 A1 It is also known to determine the particularly critical with regard to the formation of image windings diameter of the cheese and shortly before reaching one of these critical diameter to change the crossing angle to a value that precludes the formation of image windings in this diameter range. After crossing the critical diameter range of the Crossing angle returned to its original range. To change the crossing angle while the speed of the traversing yarn guide is preferably changed.

Beide Herangehensweisen zur Bildstörung haben jedoch ihre Nachteile. Die Verwendung einer Wobbelkurve verhindert zwar, dass die gesamte Bildwickelzone wirksam wird, aber durch die kontinuierliche Änderung der Changierfrequenz kann im Allgemeinen nicht verhindert werden, dass die Bildwickelzone trotzdem mehrfach kurzzeitig durchlaufen wird. Wenn die Changierfrequenz vor Erreichen eines Spulendurchmessers mit einem kritischen Windungsverhältnis verändert wird, können zwar die Bildwickel für dieses Windungsverhältnis verhindert werden, es ist jedoch nicht möglich für alle kritischen Windungsverhältnisse so zu verfahren. Neben den besonders kritischen ganzzahligen Windungsverhältnissen gibt es noch eine Vielzahl von Nebenbildern, deren Ausprägung von den Garn- und Spulenparamtern abhängt.However, both approaches to image disorder have their drawbacks. Although the use of a sweep curve prevents the entire image winding zone is effective, but by the continuous change of the traversing frequency can not be prevented in general that the image winding zone is nevertheless repeated several times briefly. If the traversing frequency is changed before reaching a coil diameter with a critical turns ratio, although the image windings for this turns ratio can be prevented, but it is not possible for all critical Windungsverhältnisse to do so. In addition to the particularly critical integer winding conditions, there are still a large number of secondary images, the expression of which depends on the yarn and coil parameters.

Aus diesem Grund wird in der EP 0 093 258 B1 vorgeschlagen, beide Bildstörverfahren miteinander zu kombinieren. Das heißt es wird eine ständige Änderung der Changiergeschwindigkeit zwischen einem Höchstwert und einem Minimalwert über vorgegebene Abschnitte der Spulreise vorgegeben und zusätzlich wird bei Annäherung an ein kritisches Windungsverhältnis, hier Spulfaktor genannt, eine zeitweilige Änderung des Mittelwertes der Changiergeschwindigkeit herbeigeführt. Es ist jedoch zu beachten, dass auch bei einer Änderung des Mittelwertes aufgrund der Wobbelung ein kritisches Windungsverhältnis mehrfach durchfahren werden kann. Deshalb wird in der EP 0 093 258 B1 vorgeschlagen, dass die Änderung des Mittelwertes derart unstetig erfolgt, dass das Windungsverhältnis einen vorgegebenen Mindestabstand von einem vorgegebenen Bild einhält und den Mindestsicherheitsabstand des Bildes sprunghaft durchfährt. Anders ausgedrückt wird hier die Änderung des Mittelwertes der Changiergeschwindigkeit so groß gewählt, dass auch die Maximalbeziehungsweise Minimalwerte der Changiergeschwindigkeit die Bildzone nicht berühren.For this reason, in the EP 0 093 258 B1 proposed to combine both Bildstörverfahren together. This means that a constant change in the traversing speed between a maximum value and a minimum value over predetermined sections of the winding cycle is predetermined and, in addition, a temporary change in the mean value of the traversing speed is brought about when approaching a critical winding ratio, here called the winding factor. However, it should be noted that even with a change in the mean value due to the sweep, a critical turn ratio can be traversed several times. That is why in the EP 0 093 258 B1 proposed that the change of the mean value takes place so discontinuously that the turns ratio maintains a predetermined minimum distance from a given image and the Minimum safety distance of the image passes by leaps and bounds. In other words, here the change in the mean value of the traversing speed is chosen to be so great that even the maximum or minimum values of the traversing speed do not touch the image zone.

Prinzipiell können auf diese Weise Bildzonen vollständig vermieden werden. Die Sprünge müssen dazu jedoch relativ groß gewählt werden, damit der Sicherheitsabstand sicher eingehalten wird. Dementsprechend tritt auch eine starke Änderung im Kreuzungswinkel auf. Dies wirkt sich negativ auf den Aufbau der wilden Wicklung aus, bei der der Kreuzungswinkel zur Erzeugung eines stabilen Garnkörpers mit einer gleichmäßigen Dichte möglichst konstant bleiben soll. Weiterhin können durch starke Änderungen des Kreuzungswickels an den Stirnflächen der Spulen so genannte Flankenringe entstehen, die eine nicht wünschenswerte optische Beeinflussung der Kreuzspule darstellen. Die Flankenringe entstehen, weil mit der Änderung des Kreuzungswinkels auch der Schleppfehler und damit die Verlegebreite der Spule verändert wird.In principle, picture zones can be completely avoided in this way. However, the jumps must be chosen to be relatively large, so that the safe distance is maintained safely. Accordingly, a large change in the crossing angle also occurs. This has a negative effect on the structure of the wild winding, in which the crossing angle should remain as constant as possible to produce a stable package with a uniform density. Furthermore, so-called flank rings, which represent an undesirable optical influence on the cross-wound bobbin, can result from pronounced changes in the crossing windings at the end faces of the bobbins. The flank rings arise because with the change of the crossing angle also the following error and thus the laying width of the coil is changed.

Ausgehend von der zuletzt genannten Schrift liegt der Erfindung die Aufgabe zugrunde, Bildzonen beim Spulen von wilden Wicklungen möglichst vollständig zu verhindern und dabei gleichzeitig negative Einflüsse auf den Spulenaufbau zu verringern.Based on the last-mentioned document, the invention is based on the object as completely as possible to prevent image zones when winding of wild windings and at the same time to reduce negative influences on the coil structure.

Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Verfahrensanspruches 1 sowie des Vorrichtungsanspruches 7 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.The object is achieved by the characterizing features of the method claim 1 and the device claim 7. Advantageous developments of the invention are the subject of the dependent claims.

Zur Lösung der Aufgabe wird die Changierfrequenz zusätzlich zur Änderung des kurzzeitigen Mittelwertes so verändert, dass der Abstand des Minimal- und des Maximalwertes bei Annäherung an das kritische Windungsverhältnis reduziert und nach dem Verlassen des kritischen Windungsverhältnisses wieder erhöht wird.To solve the problem, the traversing frequency is changed in addition to the change of the short-term average so that the distance of the minimum and maximum value is reduced when approaching the critical turns ratio and increased again after leaving the critical turns ratio.

Durch diese Maßnahme kann die sprunghafte Änderung des kurzzeitigen Mittelwertes auf ein Mindestmaß reduziert werden, so dass der Aufbau der Spule durch die Bildstörung nur wenig beeinflusst wird. Die Erfindung ermöglicht es, in den Bereichen, in denen keine Änderung des Mittelwertes erfolgt, größere Abstände des Minimal- und Maximalwertes der Changierfrequenz zuzulassen. Ein größerer Abstand wird zum Beispiel dann gewählt, wenn ein positiver Einfluss auf die Flanken der Spule gewünscht ist.As a result of this measure, the abrupt change in the short-term mean value can be reduced to a minimum, so that the structure of the coil is only slightly influenced by the image disturbance. The invention makes it possible to allow greater distances between the minimum and maximum values of the traversing frequency in the areas in which there is no change in the mean value. A larger distance is chosen, for example, if a positive influence on the flanks of the coil is desired.

Gemäß einer bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens erfolgt die Reduzierung und Erhöhung des Abstandes des Minimal- und des Maximalwertes kontinuierlich. Die Reduzierung des Abstandes erfolgt dabei vorzugsweise durch kontinuierliche Absenkung des Maximalwertes und die Erhöhung des Abstandes erfolgt durch kontinuierliche Absenkung des Minimalwertes. Die Absenkung der Extremwerte folgt dabei vorzugsweise einem hyperbolischen Verlauf. Wenn das Zeitintervall ausreichend klein ist, kann der hyperbolische Verlauf auch durch eine fallende Gerade angenähert werden. Weiterhin ist ein treppenförmiger Verlauf möglich. Durch einen hyperbolischen Verlauf der Extremwerte der Changierfrequenz weisen die Extremwerte des Windungsverhältnisses einen konstanten Verlauf auf. Es kann so ein konstantes Intervall des Windungsverhältnisses generiert werden, in dem keine tatsächlichen Windungsverhältnisse liegen. Gleichzeitig reichen die tatsächlich auftretenden Windungsverhältnisse aber nahe an dieses Intervall heran. Auf diese Weise wird die Wobbelung der Changierfrequenz nur so weit begrenzt, wie zur Vermeidung der kritischen Windungsverhältnisse unbedingt nötig ist.According to a preferred embodiment of the method according to the invention, the reduction and increase of the distance of the minimum and the maximum value takes place continuously. The reduction of the distance is preferably carried out by continuously lowering the maximum value and increasing the distance is carried out by continuously lowering the minimum value. The lowering of the extreme values preferably follows a hyperbolic course. If the time interval is sufficiently small, the hyperbolic curve can also be approximated by a falling straight line. Furthermore, a staircase-shaped course is possible. By a hyperbolic curve of the extreme values of the traversing frequency, the extreme values of the winding ratio have a constant course. It is thus possible to generate a constant interval of the turns ratio in which there are no actual turns ratios. At the same time, however, the actual winding conditions are close enough this interval. In this way, the sweep of the traversing frequency is limited only to the extent necessary to avoid the critical Windungsverhältnisse.

Die Changierfrequenz kann durch einen Nennwert, ihr Maximalwert durch eine Abweichung vom Nennwert nach oben und ihr Minimalwert durch eine Abweichung vom Nennwert nach unten definiert werden.The traversing frequency can be defined by a nominal value, its maximum value by a deviation from the rated value upwards and its minimum value by a deviation from the nominal value downwards.

Im Bereich eines kritischen Windungsverhältnisses kann die Abweichung der Changierfrequenz nach oben und unten reduziert werden. Es kann jedoch von Vorteil sein, die Abweichung entweder nach oben oder nach unten zu begrenzen. Es kann sich dabei während des Durchquerens der Bildzone ändern, welche Abweichung begrenzt wird.In the range of a critical winding ratio, the deviation of the oscillation frequency can be reduced up and down. However, it may be advantageous to limit the deviation either up or down. It may change during the crossing of the image zone, which deviation is limited.

Bei unsymmetrischer Änderung der Abweichung vom Nennwert entspricht der Nennwert nicht mehr dem Mittelwert. Sofern der Nennwert jedoch als Einstellparameter für die Changierfrequenz fungiert, wird bei Annäherung an ein kritisches Windungsverhältnis vorzugsweise diese Vorgabe sprunghaft geändert und die Abweichungen vom Nennwert werden entsprechend darauf abgestimmt. Auf diese Weise wird natürlich auch eine sprunghafte Änderung des kurzzeitigen Mittelwertes bewirkt.In the case of an asymmetrical change in the deviation from the nominal value, the nominal value no longer corresponds to the mean value. However, if the nominal value acts as an adjustment parameter for the traversing frequency, this requirement is changed abruptly when approaching a critical turns ratio and the deviations from the nominal value are adjusted accordingly. In this way, of course, a sudden change in the short-term average value is effected.

Gemäß einer vorteilhaften Ausgestaltung des erfindungsgemäßen Verfahrens wird der Abstand zwischen Minimal- und Maximalwert der Changierfrequenz bereits vor der Änderung des Nennwertes reduziert und der Abstand nimmt, erst nachdem der Nennwert seinen ursprünglichen Wert wieder annimmt, wieder zu. So kann die sprunghafte Änderung des Nennwertes beziehungsweise des kurzzeitigen Mittelwertes der Changierfrequenz auf ein Minimum beschränkt werden. Wie oben beschrieben sind zu große Sprünge in der Changierfrequenz beziehungsweise dem Windungsverhältnis schädlich für den Spulenaufbau.According to an advantageous embodiment of the method according to the invention, the distance between minimum and maximum value of the traversing frequency is reduced even before the change of the nominal value and the distance increases again only after the nominal value returns to its original value. Thus, the sudden change of the nominal value or the short-term average value of the traversing frequency can be kept to a minimum. As described above, too large jumps in the traversing frequency or the winding ratio detrimental to the coil structure.

Zur Lösung der Aufgabe wird ferner eine Vorrichtung zur Durchführung des Verfahrens zur Bildstörung beim Aufwickeln eines Fadens auf eine Kreuzspule in wilder Wicklung vorgeschlagen, wobei ein Antrieb vorhanden ist, der dazu ausgebildet ist die Kreuzspule so anzutreiben, dass die Oberflächengeschwindigkeit der Spule konstant bleibt, und wobei ein unabhängiger Antrieb mit einer Steuereinheit für die Changierung des Fadens vorhanden ist, und wobei die Steuereinheit so einstellbar ist, dass die Changierfrequenz kontinuierlich zwischen einem Minimal- und einem Maximalwert geändert wird, und die Changierfrequenz bei Annäherung an ein mittels der Steuereinheit vorgebbares kritisches Windungsverhältnis, so geändert wird, dass sich der kurzzeitige Mittelwert der Changierfrequenz sprunghaft ändert. Erfindungsgemäß ist die Steuereinheit so ausgebildet ist, dass sie bei Annäherung an das kritische Windungsverhältnis eine Reduzierung des Abstandes des Minimal- und des Maximalwertes und bei Verlassen des kritischen Windungsverhältnisses wieder eine Erhöhung des Abstandes bewirkt.To solve the problem, an apparatus for performing the method of image disturbance in winding a yarn on a cheese in wild winding is also proposed, wherein a drive is provided which is adapted to drive the cheese so that the surface velocity of the coil remains constant, and wherein an independent drive is provided with a control unit for traversing the thread, and wherein the control unit is adjustable so that the traversing frequency is continuously changed between a minimum and a maximum value, and the traversing frequency when approaching a prescribable by the control unit critical Windungsverhältnis , is changed so that the short-term mean of the oscillation frequency changes abruptly. According to the invention, the control unit is designed such that, when approaching the critical turns ratio, it brings about a reduction of the distance between the minimum and maximum values and, on leaving the critical turns ratio, again increases the distance.

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

Die Fig. 1 zeigt die Spulvorrichtung 4 einer Kreuzspulen herstellenden Textilmaschine. Wie in der Zeichnung angedeutet, liegt die in einem (nicht dargestellten) Spulenrahmen frei drehbar gehalterte Kreuzspule 8 auf einer Wickelwalze 11 auf und wird von dieser über Reibschluss mitgenommen. Die Wickelwalze 11 ist dabei an einen Antrieb 12 angeschlossen, der seinerseits über eine Steuerleitung 23 mit einer Steuereinheit 19 in Verbindung steht. Zur Verlegung des Fadens 7 während seines Auflaufens auf die Spule 8 ist außerdem eine Fadenchangiereinrichtung 16 vorgesehen, deren Changierfadenführer 18 durch einen eigenen Antrieb, vorzugsweise einen Schrittmotor 20, oszillierend angetrieben wird. Auch der Schrittmotor 20 ist über eine Steuerleitung 24 an die Steuereinheit 19 angeschlossen und von diesem definiert ansteuerbar. Des Weiteren ist eine Sensoreinrichtung 21 vorgesehen, die über eine Signalleitung 22 mit der Steuereinheit 19 verbunden ist und die die jeweilige Drehzahl der Kreuzspule 8 während des Spulprozesses erfasst. Das heißt, die Steuereinheit 19 wird mit Signalen der Sensoreinrichtung 21 versorgt und berechnet anhand der Drehzahl der Wickelwalze 11, des bekannten Durchmessers der Wickelwalze 11 sowie der durch die Sensoreinrichtung 21 ermittelten Drehzahl der Kreuzspule 8 ständig den augenblicklichen Durchmesser der Kreuzspule 8.The Fig. 1 shows the winding device 4 a cross-wound producing textile machine. As indicated in the drawing, in a (not shown) creel freely rotatably supported cross-wound bobbin 8 on a winding roller 11 and is taken from this by frictional engagement. The winding roller 11 is connected to a drive 12, which in turn is connected via a control line 23 to a control unit 19 in connection. For laying the thread 7 while it rests on the spool 8, a thread-changing device 16 is also provided, the traversing yarn guide 18 is driven by its own drive, preferably a stepping motor 20, oscillating. Also, the stepper motor 20 is connected via a control line 24 to the control unit 19 and controlled by this controlled. Furthermore, a sensor device 21 is provided, which is connected via a signal line 22 to the control unit 19 and which detects the respective rotational speed of the cross-wound bobbin 8 during the winding process. That is, the control unit 19 is supplied with signals from the sensor device 21 and calculated on the basis of the rotational speed of the winding roller 11, the known diameter of the winding roller 11 and determined by the sensor device 21 speed of the cheese 8 constantly the instantaneous diameter of the cheese 8.

Die Figuren 2 und 3 zeigen den zeitlichen Verlauf der Changierfrequenz f und des zugehörigen Windungsverhältnisses w beim Durchlaufen eines kritischen Windungsverhältnissen wK.The Figures 2 and 3 show the time course of the traversing frequency f and the associated turns ratio w when passing through a critical turns ratios w K.

Die Changierfrequenz f wird kontinuierlich mittels der Steuereinheit 19 zwischen einem Minimalwert fmin und einem Maximalwert fmax geändert. Der Minimalwert fmin und der Maximalwert fmax haben den Abstand Δf. Die Vorgabe der Changierfrequenz f erfolgt dabei mittels eines Nennwertes fN und einer Abweichung Δfmax vom Nennwert fN nach oben und einer Abweichung Δfmin von Nennwert fN noch unten. Die Steuereinheit 19 hält die Drehzahl der Wickelwalze 11 konstant und damit die Oberflächengeschwindigkeit der Kreuzspule. Die Drehzahl der Kreuzspule und damit das Windungsverhältnis nehmen hyperbolisch ab. Wie man der Fig.3 entnehmen kann, findet sich die kontinuierliche Änderung der Changierfrequenz im Windungsverhältnis wieder.The traversing frequency f is changed continuously by means of the control unit 19 between a minimum value f min and a maximum value f max . The minimum value f min and the maximum value f max have the distance Δf. The specification of the traversing frequency f is effected by means of a nominal value f N and a deviation Δf max from the nominal value f N upwards and a deviation Δf min from the nominal value f N still below. The control unit 19 keeps the speed of the winding roller 11 constant and thus the surface speed of the cheese. The speed of the cheese and thus the winding ratio decrease hyperbolic. How to get the Figure 3 can be found, is the continuous change of the traversing frequency in the turn ratio again.

Das Windungsverhältnis wK stellt ein kritisches Windungsverhältnis in Bezug auf das Entstehen von Bildwicklungen dar. Deshalb sollen die Windungsverhältnisse zwischen w1 und w2 nicht durchlaufen werden. Zum Zeitpunkt t1 erreicht das Windungsverhältnis den Wert w2. Ab diesem Zeitpunkt wird die Abweichung Δfmax vom Nennwert fN bis zum Zeitpunkt t2 kontinuierlich reduziert. Zum Zeitpunkt t2 hat der Maximalwert fmax den Nennwert fN der Changierfrequenz erreicht. Dann wird der Nennwert fN sprunghaft angehoben und anschließend wieder kontinuierlich reduziert. Gleichzeitig mit der sprunghaften Änderung des Nennwertes wird die Abweichung Δfmax wieder auf den Ursprungswert erhöht. Die Abweichung Δfmin wird dabei unterdrückt, so dass in diesem Zeitbereich der Nennwert fN dem Minimalwert der Changierfrequenz fmin entspricht. Durch die beschriebenen Maßnahmen wird das kritische Windungsverhältnis sprunghaft durchlaufen. Dann wird der Mittelwert des Windungsverhältnisses konstant gehalten, so dass das Windungsverhältnis w1 nicht mehr überschritten wird. Zum Zeitpunkt t3 hat der Nennwert fN durch die kontinuierliche Reduzierung wieder seinen ursprünglichen Wert erreicht. Dann wird die Abweichung Δfmin vom Nennwert nach unten wieder erhöht. Zum Zeitpunkt t4 hat die Changierfrequenz wieder ihren ursprünglichen Verlauf erreicht und die Bildzone wurde ohne das Entstehen vom Bildwicklungen durchlaufen.The turns ratio w K represents a critical turns ratio with respect to the formation of image windings. Therefore, the turns ratios between w 1 and w 2 should not be traversed. At time t 1 , the turns ratio reaches the value w 2 . From this point on, the deviation Δf max is continuously reduced from the nominal value f N to the time t 2 . At time t 2 , the maximum value f max has reached the nominal value f N of the traversing frequency. Then the nominal value f N is suddenly increased and then continuously reduced again. Simultaneously with the sudden change in the nominal value, the deviation Δf max is increased again to the original value. The deviation Δf min is suppressed, so that in this time range the nominal value f N corresponds to the minimum value of the traversing frequency f min . By the measures described becomes the critical turns ratio go through leaps and bounds. Then the mean value of the turns ratio is kept constant, so that the turns ratio w 1 is no longer exceeded. At time t 3 , the nominal value f N has returned to its original value due to the continuous reduction. Then the deviation Δf min is increased from the nominal value down again. At time t 4 , the traversing frequency has returned to its original course and the image zone was traversed without the formation of image windings.

Das dargestellte Ausführungsbeispiel stellt keine Einschränkung des Erfindungsgedanken dar, die Wobbelung beim sprunghaften Durchlaufen von Bildzonen zu reduzieren. Prinzipiell können bekannte Methoden des sprunghaften Durchlaufens von Bildzonen und der Wobbelung kombiniert werden und der Abstand der Extremwerte der Changierfrequenz passend so begrenzt wird, dass ein kritisches Windungsverhältnis nicht mehrfach durchlaufen wird.The illustrated embodiment does not limit the inventive idea to reduce the wobble when jumping through image zones. In principle, known methods of jumping through image zones and wobbling can be combined and the distance between the extreme values of the traversing frequency can be suitably limited such that a critical turn ratio is not passed through several times.
