  • the drive is turned off or the drive drum is subjected to an opposite moment, ie a braking torque. At this time the time measurement begins.
  • the speed of the drive drum decreases immediately.
  • the cheese of the drive drum can not follow immediately, which initially has even a higher peripheral speed than the cross-wound bobbin.
  • the speed of the cheese initially continues to increase until it reaches a maximum. Only then does the speed of the cross-wound bobbin decrease following the speed of the drive drum.

  • the speed of the cross-wound bobbin reverses, the peripheral speeds of the cheese and the drive drum have substantially approximated. If the drive drum continues to be actively braked, the drive drum may run away again. This unnecessarily generates friction and costs energy.
  • the engine is subjected to a predetermined current or drive torque for acceleration, and the acceleration time of the drive drum is used as the second time duration.
  • the acceleration time of the drive drum depends on the cross bobbin diameter with an unchanged acceleration current. Both the first time period and the second time duration increase in accordance with the cheese diameter. By dividing the diameter influence can be compensated.
  • a slip-free flow time following the first time duration is used as the second time duration.
  • the flow time increases according to the diameter of the cheese.
  • the diameter compensation works analogously.
  • the sum of the acceleration time of the drive drum and the slip-free flow time subsequent to the first time duration can be used as the second time duration.
  • the duration of the entire image disturbance cycle may also be used as the second time duration.
  • the adjustment of the acceleration phase can be done by adjusting the value of the acceleration of the drive drum. This is done by adjusting the drive torque. When the drive torque or the motor current changes, the acceleration time remains dependent on the winding parameters. According to an alternative, the duration of the acceleration of the drive drum is adjusted. This can be done, for example, by adjusting the speed limits between which the drive drum is accelerated. In this case, therefore, no concrete acceleration time will be specified, but the duration of the acceleration will be adjusted so indirectly. The acceleration time thus remains dependent on winding parameters. Of course, the duration and the value of the acceleration can also be adjusted by changing the speed specification. In this case, the acceleration time, as explained above, no longer depends on the Spulparametern.
  • the acceleration of the drive drum is adjusted when the quotient is greater than a first reference value and the acceleration of the drive drum is adjusted in the opposite direction when the quotient is smaller than a second reference value. In this way, a hysteresis is created and the quotient is kept in the band between the two reference values.
  • the control means of the device according to the invention are adapted to detect the first time duration between the maximum of the rotational speed of the drive drum and the subsequent maximum of the speed of the cross-wound bobbin, which corresponds to a first functional section within the image interference cycle, and as the second time duration a time duration dependent on the winding parameters to detect the time duration of another functional section within a frame disturbance cycle or the sum of the durations of functional sections.

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Bildstörung beim Wickeln einer Kreuzspule, die durch eine mit einer Kehrgewinderille für die Fadenführung versehene Antriebstrommel von einem Motor angetrieben wird, wobei in wiederkehrenden Bildstörzyklen die Antriebstrommel beschleunigt und verzögert wird und durch das Beschleunigen und Verzögern der Antriebstrommel ein sich ändernder Schlupf zwischen Antriebstrommel und Kreuzspule erzeugt wird. Es wird ein Quotient aus einer ersten Zeitdauer und einer zweiten Zeitdauer gebildet und die Beschleunigungsphase der Antriebstrommel wird in Abhängigkeit von einem Vergleich des Quotienten mit mindestens einem Referenzwert angepasst wird. Die Erfindung betrifft ferner eine Vorrichtung zum Wickeln einer Kreuzspule und zur Durchführung des Verfahrens. Die Vorrichtung umfasst eine Antriebstrommel mit einer Kehrgewinderille zum Antreiben einer Kreuzspule und zur Fadenführung, einen Motor zum Antreiben der Antriebstrommel und Steuermittel, die dazu ausgebildet sind, den Motor derart mit Strom zu beaufschlagen, dass die Antriebstrommel zur Erzeugung eines eine Bildstörung bewirkenden Schlupfes wiederkehrend beschleunigt und verzögert wird, einen Quotient aus einer ersten Zeitdauer und einer zweiten Zeitdauer zu bilden und die Beschleunigungsphase der Antriebstrommel in Abhängigkeit von einem Vergleich des Quotienten mit mindestens einem Referenzwert anzupassen.The present invention relates to a method of disordering the winding of a package, which is driven by a provided with a Kehrgewinderille for thread guide drive motor by a motor, wherein in repetitive Bildstörzyklen the drive drum is accelerated and decelerated and by accelerating and decelerating the drive drum a changing slip between the drive drum and cross-wound bobbin is generated. A quotient of a first time duration and a second time duration is formed, and the acceleration phase of the drive drum is adjusted as a function of a comparison of the quotient with at least one reference value. The invention further relates to a device for winding a cross-wound bobbin and for carrying out the method. The apparatus comprises a drive drum having a reciprocating groove for driving a cheese and thread guide, a motor for driving the drive drum, and control means configured to energize the motor so as to repetitively accelerate the drive drum to produce a slip causing discrepancy and delaying forming a quotient of a first time period and a second time duration and adjusting the acceleration phase of the drive drum in response to a comparison of the quotient with at least one reference value.

Bei der gattungsgemäßen DE 37 03 869 A1 werden die Umlaufzeiten der Antriebstrommel und der Kreuzspule gemessen und laufend oder intermittierend miteinander verglichen. Der Vergleich erfolgt beispielsweise durch die Bildung eines Quotienten aus den Umlaufzeiten. Der Quotient kann mit Sollwerten verglichen werden. Bei Abweichungen des Vergleichsergebnisses mit den Sollwerten wird in den Spulvorgang eingegriffen und die Antriebsvorrichtung der Antriebstrommel gesteuert oder geregelt. Das Verfahren findet auch in Verbindung mit einem Bildstörungsverfahren Anwendung.In the generic DE 37 03 869 A1 The circulation times of the drive drum and the cheese are measured and compared continuously or intermittently. The comparison is made, for example, by the formation of a quotient of the circulation times. The quotient can be compared with setpoints. In case of deviations of the comparison result with the desired values, the winding process is intervened and the drive device of the drive drum is controlled or regulated. The method also finds application in connection with a picture disturbance method.

Die DE 195 19 542 A1 offenbart ein Verfahren und eine Vorrichtung zur Vermeidung von Bildwicklungen beim Wickeln einer Kreuzspule, die durch eine mit einer Kehrgewinderille für die Fadenführung versehenen Antriebstrommel angetrieben wird. Eine solche Antriebstrommel wird auch als Nutentrommel bezeichnet.The DE 195 19 542 A1 discloses a method and apparatus for preventing image windings when winding a cross-wound bobbin, which is driven by a drive drum provided with a thread guide groove for the thread guide. Such a drive drum is also referred to as grooved drum.

Mittels einer Nutentrommel werden Kreuzspulen mit konstantem Kreuzungswinkel gefertigt. Konstruktionsbedingt ist das Verhältnis der Umfangsgeschwindigkeit der Kreuzspule zur Changierfrequenz des Fadens konstant. Das Windungsverhältnis, das heißt die Drehzahl der Kreuzspule im Verhältnis zur Changierfrequenz des Fadens, nimmt dabei mit zunehmendem Durchmesser ab. Bei bestimmten Windungsverhältnissen treten sogenannte Bildwicklungen auf. Dabei wird der Faden während einer größeren Anzahl von Umdrehungen stets in einem schmalen Bereich auf dem Umfang der Kreuzspule abgelegt, wodurch das Ablaufverhalten einer Kreuzspule negativ beeinflusst wird.By means of a grooved drum cheeses are manufactured with a constant crossing angle. By design, the ratio of the peripheral speed of the cheese to the traversing frequency of the thread is constant. The turns ratio, that is the speed of the cross-wound bobbin in relation to the traversing frequency of the thread, decreases as the diameter increases. At certain Windungsverhältnissen occur so-called image windings. In this case, the yarn is always stored in a narrow range on the circumference of the cross-wound bobbin during a larger number of revolutions, whereby the flow behavior of a cross-wound bobbin is adversely affected.

Durch ein wiederkehrendes Beschleunigen und Verzögern der Antriebstrommel entsteht ein ständig wechselnder Schlupf zwischen Antriebstrommel und Kreuzspule. Der Schlupf ist dabei eine Abweichung zwischen den Umfangsgeschwindigkeiten der Antriebstrommel und der Kreuzspule. Durch den wechselnden Schlupf wird dem langsam und kontinuierlich abnehmenden Windungsverhältnis ein ständiger Wechsel überlagert. Das Entstehen von Bildwicklungen kann auf diese Weise weitestgehend verhindert werden.Through a recurring acceleration and deceleration of the drive drum creates a constantly changing slip between the drive drum and cross-wound bobbin. The slip is a deviation between the peripheral speeds of the drive drum and the cross-wound bobbin. Due to the alternating slip, a constant change is superimposed on the slowly and continuously decreasing turn ratio. The emergence of image windings can be prevented in this way as far as possible.

Die Antriebstrommel kann durch einen elektrischen Motor angetrieben werden. Der Motor übt ein Moment auf die Antriebstrommel aus und bewirkt damit die gewünschte Beschleunigung. Damit der Motor das erforderliche Moment ausübt, wird er mit einem Strom beaufschlagt. Beim Ausschalten des Motors wirkt nur noch das durch Reibung bedingte Bremsmoment auf die Antriebstrommel. Durch dieses Reibmoment wird die Antriebstrommel beim Ausschalten des Motors verzögert. Durch geeignete Beaufschlagung des Motors mit Strom kann der Motor in den Verzögerungsphasen aber auch ein zusätzliches Bremsmoment ausüben.The drive drum can be driven by an electric motor. The motor exerts a moment on the drive drum and thus causes the desired acceleration. For the motor to exert the required torque, it is supplied with a current. When the engine is switched off, only the friction torque due to friction acts on the drive drum. This friction torque delays the drive drum when the engine is switched off. However, by applying a suitable current to the motor, the motor can also exert an additional braking torque in the deceleration phases.

Üblicherweise wird die Drehzahl der Antriebstrommel zwischen vorgegebenen Grenzen variiert. Der Motor übt vorgegebene Beschleunigungs- und Bremsmomente aus. Der tatsächliche Schlupf kann dabei jedoch stark variieren, da er nicht nur von den Motormomenten, sondern auch von den jeweiligen Spulparametern abhängt. Solche Spulparameter, die den Schlupf beeinflussen, sind zum Beispiel der Auflagedruck, die Fadenspannung, die Paraffinierung und der Kreuzspulendurchmesser.Usually, the speed of the drive drum is varied between predetermined limits. The engine exerts specified acceleration and braking torques. However, the actual slip can vary greatly, as it depends not only on the engine torque, but also on the respective winding parameters. Such winding parameters which influence the slip are, for example, the contact pressure, the thread tension, the waxing and the cheese diameter.

Um den tatsächlichen Schlupf zu bestimmen, ist die Kenntnis der Umfangsgeschwindigkeiten von Antriebstrommel und Kreuzspule erforderlich. Die Umfangsgeschwindigkeit der Antriebstrommel lässt sich leicht aus der Drehzahl der Antriebstrommel und dem bekannten Durchmesser der Antriebstrommel bestimmen. Bei der Kreuzspule ändert sich der Durchmesser während des Wickelvorganges, so dass eine Ermittlung der Umfangsgeschwindigkeit aus der gemessenen Drehzahl nicht ohne weiteres möglich ist.In order to determine the actual slip, it is necessary to know the peripheral speeds of the drive drum and cross-wound bobbin. The peripheral speed of the drive drum can be easily determined from the speed of the drive drum and the known diameter of the drive drum. In the cheese, the diameter changes during the winding process, so that a determination of the peripheral speed of the measured speed is not readily possible.

Die WO 2008/107170 A1 betrifft insbesondere die genaue Messung der Spulbeziehungsweise Fadengeschwindigkeit und dazu geeignete Vorrichtungen. Die Spulgeschwindigkeit entspricht angenähert der Umfangsgeschwindigkeit der Kreuzspule. Der Schlupf soll aus der Spulgeschwindigkeit und der Trommeldrehzahl ermittelt werden. Um den Schlupf zu bestimmen, sind also zusätzliche Sensoren erforderlich. Es wird erläutert, dass es so möglich ist, den durch ein Bildstörverfahren gezielt erzeugten Schlupf zwischen der Nutentrommel und der Kreuzspule zu überwachen. Wenn der Schlupf von einem bestimmten Zielwert abweicht oder einen bestimmten Grenzwert über- oder unterschreitet, kann ein Warnsignal ausgegeben und/oder vorteilhafterweise der Bildstörhub durch eine Steuereinheit automatisch korrigiert werden.The WO 2008/107170 A1 in particular, relates to the accurate measurement of coiling and yarn speed and suitable devices. The winding speed corresponds approximately to the peripheral speed of the cross-wound bobbin. The slip should be determined from the winding speed and the drum speed. To determine the slip, so additional sensors are required. It will be explained that it is thus possible to monitor the slippage between the grooved drum and the cross-wound bobbin in a targeted manner by means of a picture disturbing method. If the slip deviates from a certain target value or exceeds or falls below a certain threshold value, a warning signal can be output and / or advantageously the image disturbance can be automatically corrected by a control unit.

Bereits in der DE 196 25 510 A1 wurde ein Verfahren offenbart, das in Verbindung mit dem oben beschriebenen Bildstörverfahren die Ermittlung des Schlupfes nur aus den Drehzahlen von Antriebstrommel und Kreuzspule ermöglicht. Zum Ende der Verzögerungsphase, wenn die Antriebstrommel nicht oder nicht mehr angetrieben wird, rotieren Antriebstrommel und Kreuzspule annähernd schlupffrei. In dieser schlupffreien Auslaufphase wird aus den beiden Drehzahlen der tatsächliche Kreuzspulendurchmesser ermittelt. Wenn kein Schlupf vorhanden ist, stimmt das Verhältnis der Drehzahlen mit dem Verhältnis der Durchmesser von Antriebstrommel und Kreuzspule überein. Aus dem Verlauf des Kreuzspulendurchmessers über mehrere Auslaufphasen kann die Zunahme des Kreuzspulendurchmessers in den Beschleunigungsphasen vorausberechnet werden. Darüber hinaus kann analog zu den Auslaufphasen in der Beschleunigungsphase ein durch den Schlupf verfälschter Durchmesser berechnet werden. Aus der Abweichung beider für die Beschleunigungsphase ermittelten Durchmesser lässt sich der Schlupf berechnen. Die Istwerte des Schlupfes werden mit Sollwerten verglichen und bei Abweichungen werden ein oder mehrere Betriebsparameter der Spulvorrichtung als Stellgröße zum Einregeln der Istwerte auf die Sollwerte verändert. Damit ist es möglich, die Dauer der Beschleunigungsphasen so festzulegen, dass einerseits ein ausreichender und andererseits aber auch kein zu hoher Schlupf entsteht. Damit wird nicht nur die Qualität einer Spule aufgrund einer effektiven Bildstörung verbessert, sondern zusätzlich auch noch der Energieverbrauch der Spulvorrichtung optimiert.
Einrichtungen zum Erfassen der Drehzahlen von Antriebstrommel und Kreuzspule werden in der Regel zur Ermittlung des Kreuzspulendurchmessers ohnehin benötigt. Die Lösung der DE 196 25 510 A1 erfordert also keine zusätzlichen Sensoren. Die Berechnung des Schlupfes, insbesondere die Extrapolation des tatsächlichen Kreuzspulendurchmessers während der Beschleunigungsphasen, erfordert jedoch einen gewissen Rechenaufwand und belegt damit Prozessorleistung.Already in the DE 196 25 510 A1 For example, a method has been disclosed which, in conjunction with the above-described image disturbance method, enables the determination of slip only from the speeds of the drive drum and cross-wound bobbin. At the end of the deceleration phase, when the drive drum is not or no longer driven, drive drum and cross-wound bobbin rotate almost without slippage. In this slip-free phase-out phase, the actual cheese diameter is determined from the two speeds. If there is no slippage, the ratio of the speeds is correct coincide with the ratio of the diameter of the drive drum and cross-wound bobbin. From the course of the cross-coil diameter over several run-out phases, the increase of the cross-coil diameter in the acceleration phases can be predicted. In addition, analogous to the phase-out phases in the acceleration phase, a diameter which is falsified by the slip can be calculated. From the deviation of both determined for the acceleration phase diameter, the slip can be calculated. The actual values of the slip are compared with nominal values and, in the case of deviations, one or more operating parameters of the winding device are changed as a manipulated variable for adjusting the actual values to the nominal values. Thus, it is possible to set the duration of the acceleration phases so that on the one hand sufficient and on the other hand no too high slip occurs. This not only improves the quality of a coil due to an effective image disturbance, but also optimizes the energy consumption of the winding device.
Means for detecting the rotational speeds of the drive drum and cross-wound bobbin are generally required to determine the cross-coil diameter anyway. The solution of DE 196 25 510 A1 does not require additional sensors. The calculation of the slip, in particular the extrapolation of the actual cheese diameter during the acceleration phases, however, requires a certain amount of computation and thus proves processor performance.

Es ist die Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung zur Verfügung zu stellen, die auf einfache Weise ein selbsttätiges Einstellen eines gewünschten Schlupfes unabhängig von den Spulparametern ermöglichen, der eine ausreichende Bildstörung ermöglicht und keine unnötige Energie verbraucht.It is the object of the present invention to provide a method and a device which allow, in a simple manner, an automatic setting of a desired slip independently of the winding parameters, which enables a sufficient picture disturbance and does not consume unnecessary energy.

Zur Lösung der Aufgabe wird die erste Zeitdauer zwischen dem Maximum der Drehzahl der Antriebstrommel und dem darauffolgenden Maximum der Drehzahl der Kreuzspule, die einem ersten Funktionsabschnitt innerhalb des Bildstörzyklus' entspricht, erfasst und als zweite eine von den Spulparametern abhängige Zeitdauer, die der Zeitdauer eines anderen Funktionsabschnittes innerhalb eines Bildstörzyklus' oder der Summe der Zeitdauern von Funktionsabschnitten entspricht, erfasst.To solve the problem, the first period of time between the maximum of the rotational speed of the drive drum and the subsequent maximum of the speed of the cheese, which corresponds to a first functional section within the Bildstörzyklus' detected and second as a dependent on the Spulparametern time duration, the time duration of another Function section within a Bildstörzyklus' or the sum of the durations of functional sections corresponds detected.

Der Erfindung liegt die Idee zu Grunde, dass die Kenntnis eines Absolutwertes des Schlupfes zur Einstellung beziehungsweise Regelung eines für die Bildstörung optimalen Schlupfes gar nicht erforderlich ist. Es reicht aus, eine Größe zu bestimmen, die ein Maß für den Schlupf darstellt und unabhängig von sonstigen Einflüssen ist. Die Zeitmessung zur Erfassung der Zeit beziehungsweise des Zeitraumes gemäß der vorliegenden Erfindung lässt sich mit moderner Steuerungstechnik einfach umsetzen. Die Drehzahl der Antriebstrommel wird in der Regel vorgegeben. Die Antriebstrommel bewegt sich dann zwischen vorgegebenen Drehzahlgrenzen, das heißt zwischen einer unteren und einer oberen Grenze. Deshalb ist bereits bekannt, wann das Maximum der Drehzahl der Antriebstrommel erreicht ist. Wenn die Antriebstrommel eine vorgegebene Drehzahl erreicht hat, wird der Antrieb ausgeschaltet oder die Antriebstrommel wird mit einem entgegengesetzten Moment, also einem Bremsmoment, beaufschlagt. Zu diesem Zeitpunkt beginnt die Zeitmessung. Die Drehzahl der Antriebstrommel nimmt sofort ab. Aufgrund der Trägheit der Kreuzspule kann die Kreuzspule der Antriebstrommel nicht sofort folgen, die ja zunächst noch eine höhere Umfangsgeschwindigkeit als die Kreuzspule besitzt. Die Drehzahl der Kreuzspule steigt zunächst weiter an, bis sie ein Maximum erreicht hat. Erst dann nimmt die Drehzahl der Kreuzspule der Drehzahl der Antriebstrommel folgend ab. Das Maximum der Drehzahl der Kreuzspule lässt sich leicht durch einen Vergleich eines aktuellen Drehzahlwertes mit einem zuvor ermittelten Drehzahlwert bestimmen. Wenn der aktuelle Wert kleiner oder gleich dem vorigen Wert ist, ist das Maximum erreicht und die Zeitmessung kann gestoppt werden.The invention is based on the idea that the knowledge of an absolute value of the slip to set or regulate an optimum for the image disturbance slip is not required. It is sufficient to determine a size that is a measure of the slip and is independent of other influences. The time measurement for detecting the time or the time period according to the present invention can be easily implemented with modern control technology. The speed of the drive drum is usually specified. The drive drum then moves between predetermined speed limits, that is between a lower and an upper limit. Therefore, it is already known when the maximum speed of the drive drum is reached. When the drive drum has reached a predetermined speed, the drive is turned off or the drive drum is subjected to an opposite moment, ie a braking torque. At this time the time measurement begins. The speed of the drive drum decreases immediately. Due to the inertia of the cheese, the cheese of the drive drum can not follow immediately, which initially has even a higher peripheral speed than the cross-wound bobbin. The speed of the cheese initially continues to increase until it reaches a maximum. Only then does the speed of the cross-wound bobbin decrease following the speed of the drive drum. The maximum of the speed of the cheese can be easily determined by comparing a current speed value with a previously determined speed value. If the current value is less than or equal to the previous value, the maximum is reached and the time measurement can be stopped.

Der Zeitpunkt der Drehzahlumkehr der Kreuzspule hängt stark vom Schlupf ab. Je größer der Schlupf, desto größer ist die Zeitdauer vom Beginn der Verzögerung der Antriebstrommel bis zur Drehzahlumkehr der Kreuzspule. Diese Zeitdauer hängt allerdings auch stark von anderen Faktoren ab, insbesondere von dem Kreuzspulendurchmesser. Es dauert länger eine große Kreuzspule abzubremsen als eine kleine.The time of the speed reversal of the cross-wound bobbin strongly depends on the slip. The greater the slip, the greater the time from the beginning of the delay of the drive drum to the speed reversal of the cheese. However, this period of time also depends strongly on other factors, in particular on the cheese diameter. It takes longer to decelerate a large cheese than a small one.

Um die Abhängigkeit von den anderen Parametern zu kompensieren, wird eine zweite von den Spulparametern abhängige Zeitdauer bestimmt. Diese gehört zu einem Funktionsabschnitt des gleichen Bildstörzyklus' und wird damit mit den gleichen Spulparametern, insbesondere dem gleichen Durchmesser, durchgeführt. Indem man beide Zeitdauern ins Verhältnis setzt, werden diese Einflussgrößen kompensiert und der Quotient hängt im Wesentlichen nur noch vom Schlupf ab. Die zweite Zeitdauer lässt sich ebenfalls leicht bestimmen, da Funktionsabschnitte in der Regel in Abhängigkeit bestimmter Zustände oder Messwerte durch Steuereingriffe eingeleitet und beendet werden. Die Zeitpunkte zu denen eine Zeiterfassung gestartet und beendet werden muss, sind als ohnehin bekannt.In order to compensate for the dependence on the other parameters, a second time period dependent on the spooling parameters is determined. This belongs to a functional section of the same Bildstörzyklus' and is thus performed with the same Spulparametern, in particular the same diameter. By putting both time periods in relation, these factors are compensated and the Quotient depends essentially only on the slip. The second period of time can likewise be easily determined since functional sections are generally initiated and terminated as a function of specific states or measured values by means of control interventions. The times at which time recording has to be started and ended are known as already known.

Erfindungsgemäß wird damit auf einfache Weise ein Verhältnis bestimmt, das ein von sonstigen Parametern weitgehend freies Maß für den Schlupf darstellt. Dieses Verhältnis beziehungsweise dieser Quotient kann dann mit einem Referenzwert verglichen werden und so die Parameter der nächsten Beschleunigungsphase bestimmt werden. Der Referenzwert ist unabhängig von den Spulparametern. Der Referenzwert hängt nur von der gewünschten Bildstörung beziehungsweise der gewünschten Energieersparnis ab. Der Referenzwert beziehungsweise die Referenzwerte lassen sich also mit wenig Aufwand empirisch bestimmen. Das ist ein einmaliger Vorgang, da die Referenzwerte, wie oben bereits erläutert, nicht von den Spulparametern abhängen.According to the invention a ratio is thus determined in a simple manner, which is a measure of the slip largely free of other parameters. This ratio or quotient can then be compared with a reference value and thus the parameters of the next acceleration phase can be determined. The reference value is independent of the winding parameters. The reference value depends only on the desired image disturbance or the desired energy savings. The reference value or the reference values can therefore be determined empirically with little effort. This is a one-time process because the reference values, as explained above, do not depend on the spooling parameters.

Vorzugsweise wird ein Motor zum Antreiben der Antriebstrommel zum Verzögern nur für die erste Zeitdauer mit einem Bremsstrom beaufschlagt. Das heißt, der Bremsstrom wird zur Einleitung des Bremsvorganges eingeschaltet und beim Maximum der Drehzahl der Kreuzspule wieder ausgeschaltet. Die Antriebstrommel und die Kreuzspule laufen dann nur gebremst durch die Reibmomente aus. Eine längere Beaufschlagung mit einem Bremsstrom wäre unter Umständen kontraproduktiv. Wenn sich die Drehzahl der Kreuzspule umkehrt, haben sich die Umfangsgeschwindigkeiten der Kreuzspule und der Antriebstrommel im Wesentlichen angenähert. Wenn die Antriebstrommel weiter aktiv gebremst wird, kann die Antriebstrommel wieder weglaufen. Das erzeugt unnötig Reibung und kostet Energie. Durch den beschriebenen Ablauf der Bremsstrombeaufschlagung wird also der Bremsvorgang optimiert und verbraucht weniger Energie.Preferably, a motor for driving the drive drum for decelerating is applied with a braking current only for the first period of time. That is, the braking current is turned on to initiate the braking process and turned off again at the maximum of the speed of the cheese. The drive drum and the cheese then run only braked by the friction moments. Prolonged application of a braking current might be counterproductive. When the speed of the cross-wound bobbin reverses, the peripheral speeds of the cheese and the drive drum have substantially approximated. If the drive drum continues to be actively braked, the drive drum may run away again. This unnecessarily generates friction and costs energy. By the described flow of Bremsstrombeaufschlagung so the braking process is optimized and consumes less energy.

Gemäß einer bevorzugten Ausführungsform wird der Motor zur Beschleunigung mit einem vorgegebenen Strom beziehungsweise Antriebsmoment beaufschlagt und als zweite Zeitdauer wird die Beschleunigungszeit der Antriebstrommel verwendet. Das entspricht der Zeitdauer, die die Antriebstrommel zur Beschleunigung von einer unteren Grenzdrehzahl auf eine obere Grenzdrehzahl benötigt. Da nicht nur die Antriebstrommel selber, sondern auch die aufliegende Kreuzspule beschleunigt werden muss, hängt die Beschleunigungszeit der Antriebstrommel bei unverändertem Beschleunigungsstrom von dem Kreuzspulendurchmesser ab. Sowohl die erste Zeitdauer als auch die zweite Zeitdauer steigt entsprechend dem Kreuzspulendurchmesser an. Durch eine Division lässt sich der Durchmessereinfluss kompensieren.According to a preferred embodiment, the engine is subjected to a predetermined current or drive torque for acceleration, and the acceleration time of the drive drum is used as the second time duration. This corresponds to the length of time required by the drive drum to accelerate from a lower limit speed to an upper limit speed. Not just the drive drum itself, but also the overlying cross-wound bobbin must be accelerated, the acceleration time of the drive drum depends on the cross bobbin diameter with an unchanged acceleration current. Both the first time period and the second time duration increase in accordance with the cheese diameter. By dividing the diameter influence can be compensated.

Es ist auch möglich, der Antriebstrommel durch eine entsprechende Regelung einen Drehzahlverlauf vorzugeben. In diesem Fall werden Spulparameter durch die Regelung kompensiert und die Beschleunigungszeit hängt nicht von den Spulparametern ab. In diesem Fall kann die Beschleunigungszeit nicht als zweite Zeitdauer verwendet werden. Für das erfindungsgemäße Verfahren muss für die zweite Zeitdauer ein anderer Funktionsabschnitt gewählt werden.It is also possible to predetermine the speed of the drive drum by an appropriate control. In this case, winding parameters are compensated by the control and the acceleration time does not depend on the winding parameters. In this case, the acceleration time can not be used as the second time period. For the method according to the invention, a different functional section must be selected for the second time period.

Gemäß einer alternativen Ausführungsform wird als zweite Zeitdauer eine an die erste Zeitdauer anschließende schlupffreie Auslaufzeit verwendet. Die Auslaufzeit erhöht sich entsprechend dem Kreuzspulendurchmesser. Die Durchmesserkompensation funktioniert analog.According to an alternative embodiment, a slip-free flow time following the first time duration is used as the second time duration. The flow time increases according to the diameter of the cheese. The diameter compensation works analogously.

Als weitere Alternative kann als zweite Zeitdauer die Summe der Beschleunigungszeit der Antriebstrommel und der an die erste Zeitdauer anschließende schlupffreie Auslaufzeit verwendet werden.As a further alternative, the sum of the acceleration time of the drive drum and the slip-free flow time subsequent to the first time duration can be used as the second time duration.

Die Zeitdauer des gesamten Bildstörungszyklus' kann ebenfalls als zweite Zeitdauer verwendet werden.The duration of the entire image disturbance cycle may also be used as the second time duration.

Die Anpassung der Beschleunigungsphase kann durch Anpassung des Wertes der Beschleunigung der Antriebstrommel erfolgen. Dies geschieht durch Anpassen des Antriebsmomentes. Bei einer Änderung des Antriebsmomentes beziehungsweise des Motorstromes bleibt die Beschleunigungszeit von den Spulparametern abhängig. Gemäß einer Alternative wird die Dauer der Beschleunigung der Antriebstrommel angepasst. Das kann zum Beispiel durch eine Anpassung der Drehzahlgrenzen erfolgen, zwischen denen die Antriebstrommel beschleunigt wird. In diesem Fall wird also keine konkrete Beschleunigungszeit vorgeben, sondern die Dauer der Beschleunigung wird so indirekt angepasst. Die Beschleunigungszeit bleibt damit von Spulparametern abhängig. Die Dauer und der Wert der Beschleunigung lassen sich natürlich auch durch eine Änderung der Drehzahlvorgabe anpassen. In diesem Fall ist die Beschleunigungszeit, wie oben erläutert, nicht mehr von den Spulparametern abhängig.The adjustment of the acceleration phase can be done by adjusting the value of the acceleration of the drive drum. This is done by adjusting the drive torque. When the drive torque or the motor current changes, the acceleration time remains dependent on the winding parameters. According to an alternative, the duration of the acceleration of the drive drum is adjusted. This can be done, for example, by adjusting the speed limits between which the drive drum is accelerated. In this case, therefore, no concrete acceleration time will be specified, but the duration of the acceleration will be adjusted so indirectly. The acceleration time thus remains dependent on winding parameters. Of course, the duration and the value of the acceleration can also be adjusted by changing the speed specification. In this case, the acceleration time, as explained above, no longer depends on the Spulparametern.

Es ist möglich, nur einen Referenzwert zu verwenden und bei Über- oder Unterschreiten des Referenzwertes den Wert oder die Dauer der Beschleunigung entsprechend nach oben oder unten anzupassen.It is possible to use only one reference value and to adjust the value or the duration of the acceleration correspondingly up or down when the reference value is overshot or undershot.

Gemäß einem alternativen Verfahren wird die Beschleunigung der Antriebstrommel angepasst, wenn der Quotient größer ist als ein erster Referenzwert und die Beschleunigung der Antriebstrommel wird in entgegengesetzter Richtung angepasst, wenn der Quotient kleiner ist als ein zweiter Referenzwert. Auf diese Weise entsteht eine Hysterese und der Quotient wird in dem Band zwischen den beiden Referenzwerten gehalten.According to an alternative method, the acceleration of the drive drum is adjusted when the quotient is greater than a first reference value and the acceleration of the drive drum is adjusted in the opposite direction when the quotient is smaller than a second reference value. In this way, a hysteresis is created and the quotient is kept in the band between the two reference values.

Zur Lösung der Aufgabe wird ferner eine Vorrichtung zur Durchführung des Verfahrens vorgeschlagen. Die Steuermittel der Vorrichtung sind erfindungsgemäß dazu ausgebildet, die erste Zeitdauer zwischen dem Maximum der Drehzahl der Antriebstrommel und dem darauffolgenden Maximum der Drehzahl der Kreuzspule, die einem ersten Funktionsabschnitt innerhalb des Bildstörzyklus' entspricht, zu erfassen und als zweite Zeitdauer eine von den Spulparametern abhängige Zeitdauer, die der Zeitdauer eines anderen Funktionsabschnittes innerhalb eines Bildstörzyklus' oder der Summe der Zeitdauern von Funktionsabschnitten entspricht, zu erfassen.To solve the problem, a device for carrying out the method is also proposed. The control means of the device according to the invention are adapted to detect the first time duration between the maximum of the rotational speed of the drive drum and the subsequent maximum of the speed of the cross-wound bobbin, which corresponds to a first functional section within the image interference cycle, and as the second time duration a time duration dependent on the winding parameters to detect the time duration of another functional section within a frame disturbance cycle or the sum of the durations of functional sections.

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.

a device for winding a cross-wound bobbin;

a time course of the peripheral speeds of the drive drum and cross-wound bobbin.

Die Fig. 1 zeigt eine Vorrichtung 1 zum Wickeln einer Kreuzspule 2. Es handelt sich dabei um einen Teil einer Arbeitsstelle einer Kreuzspulen herstellenden Textilmaschine. Solche Kreuzspulen herstellenden Textilmaschinen sind zum Beispiel Spulmaschinen, die einen Faden von einer Ablaufspule auf die Kreuzspule 2 wickeln, oder Rotorspinnmaschinen, bei denen ein gesponnener Faden direkt auf eine Kreuzspule gewickelt wird.The Fig. 1 shows a device 1 for winding a cross-wound bobbin 2. It is a part of a job of a cheese-producing textile machine. Such cross-wound textile machines are, for example, winding machines that wind a thread from a delivery bobbin on the cheese 2, or rotor spinning machines, in which a spun yarn is wound directly onto a cross-wound bobbin.

Die Wickelvorrichtung umfasst einen Spulenrahmen 4 zum Haltern der Kreuzspule 2. Die Kreuzspule 2 liegt auf einer Antriebstrommel 3 mit einer Kehrgewinderille 9 auf. Die Antriebstrommel 3 nimmt die Kreuzspule 2 über Reibschluss mit. Die Kehrgewinderille 9 sorgt dafür, dass der Faden in kreuzförmigen Fadenlagen auf der Umfangsfläche abgelegt wird. Die Antriebstrommel 3 wird von dem Motor 7 angetrieben. Beide sind direkt über die Welle 13 gekoppelt und rotieren deshalb mit der gleichen Drehzahl. Die Wickelvorrichtung 1 verfügt ferner über eine Steuerung 8. Die Steuerung 8 beaufschlagt den Motor 7 mit Strom. Der Strom bewirkt ein definiertes Motormoment, das auf die Antriebstrommel 3 übertragen wird.The winding device comprises a creel 4 for holding the cross-wound bobbin 2. The cheese 2 rests on a drive drum 3 with a Kehrgewinderille 9. The drive drum 3 takes the cheese 2 via frictional engagement. The Kehrgewinderille 9 ensures that the thread is deposited in cross-shaped thread layers on the peripheral surface. The drive drum 3 is driven by the motor 7. Both are coupled directly via the shaft 13 and therefore rotate at the same speed. The winding device 1 also has a controller 8. The controller 8 supplies the motor 7 with electricity. The current causes a defined engine torque, which is transmitted to the drive drum 3.

Die Steuerung 8 wertet außerdem die Signale der Sensoren 5 und 6 aus. Der Sensor 5 misst die Drehzahl der Kreuzspule 2 und der Sensor 6 misst die Drehzahl der Antriebstrommel 3. In dem dargestellten Ausführungsbeispiel ist der Sensor 6 am Motor 7 angebracht, der die gleiche Drehzahl aufweist wie die Antriebstrommel 3. Alternativ kann die Drehzahl auch direkt an der Antriebstrommel gemessen werden. Es ist auch möglich, die Drehzahl der Antriebstrommel 3 sensorlos aus den elektrischen Größen des Motors 7 zu bestimmen.The controller 8 also evaluates the signals from the sensors 5 and 6. The sensor 5 measures the speed of the cheese 2 and the sensor 6 measures the speed of the drive drum 3. In the illustrated embodiment, the sensor 6 is mounted on the motor 7, which has the same speed as the drive drum 3. Alternatively, the speed also directly to the drive drum are measured. It is also possible to determine the speed of the drive drum 3 sensorless from the electrical variables of the motor 7.

Die Fig. 2 stellt den zeitlichen Verlauf der Umfangsgeschwindigkeiten von Antriebstrommel 3 und Kreuzspule 2 dar. Die Umfangsgeschwindigkeiten sind in den schlupffreien Phasen identisch. Beim Auftreten eines Schlupfes ist die Abweichung der Umfangsgeschwindigkeiten nur gering. Die Drehzahlen von Antriebstrommel 3 und Kreuzspule 2 können dagegen in Abhängigkeit von dem Durchmesser der Antriebstrommel 3 und der Kreuzspule 2 deutlich voneinander abweichen. Die Drehzahl der Antriebstrommel 3 ist stets proportional zu ihrer Umfangsgeschwindigkeit. Die Drehzahl der Kreuzspule nimmt mit wachsendem Durchmesser ab. Die Lage der Extremwerte, auf die es bei der vorliegenden Erfindung ankommt, ist jedoch gleich unabhängig davon, ob die Umfangsgeschwindigkeit oder die Drehzahl ausgewertet wird. Das gilt gleichermaßen für die Antriebstrommel 3 und für die Kreuzspule 2.The Fig. 2 represents the time course of the peripheral speeds of drive drum 3 and cross-wound bobbin 2. The peripheral speeds are identical in the slip-free phases. When a slip occurs, the deviation of the peripheral speeds is only slight. The speeds of drive drum 3 and cross-wound bobbin 2, however, may vary depending on the diameter of the drive drum 3 and the cheese 2 differ significantly. The speed of the drive drum 3 is always proportional to its peripheral speed. The speed of the cross-wound bobbin decreases with increasing diameter. However, the location of the extreme values, which are important in the present invention, is the same irrespective of whether the peripheral speed or the rotational speed is evaluated. This applies equally to the drive drum 3 and the cross-wound bobbin 2.

Aus oben erläuterten Gründen wird die erfindungsgemäße Bildstörung anhand der Darstellung der Umfangsgeschwindigkeiten in Fig. 2 erläutert. Die beschriebenen Auswertungen werden von der Steuerung 8 ausgeführt und der Motor 7 wird von der Steuerung 8 mit dem entsprechenden Strom beaufschlagt. Der Kurvenverlauf 10 stellt die Umfangsgeschwindigkeit der Antriebstrommel 3 dar. Um einen Schlupf zwischen der Antriebstrommel 3 und der Kreuzspule 2 zu erzeugen, wird die Antriebstrommel durch ein geeignetes Motormoment beschleunigt. Die Beschleunigung startet zum Zeitpunkt t0. In Fig. 2 ist der Anstieg der Geschwindigkeit linear. Das heißt, in der Beschleunigungsphase ist das Motormoment konstant. Es ist aber genauso möglich, einen anderen Kurvenverlauf zu verwenden. Wichtig ist nur, dass die Antriebstrommel beschleunigt wird. Der Kurvenverlauf 11, der die Umfangsgeschwindigkeit der Kreuzspule 2 darstellt, folgt der Kurve 10 nur verzögert. Der Abstand 12 zwischen den Kurven 10 und 11 ist der Schlupf. Wenn zum Zeitpunkt t1 die Antriebstrommel 3 eine vorgegebene Drehzahl beziehungsweise eine vorgegebene Umfangsgeschwindigkeit v2 erreicht hat, wird der Motorstrom verändert und die Antriebstrommel durch den Motor 7 mit einem Bremsmoment beaufschlagt. Dann wird der Motor 7 ausgeschaltet. Die vorhandenen Reibmomente sorgen dafür, dass die Trommeldrehzahl weiter abnimmt. Im Prinzip ist es auch möglich, die Antriebstrommel 3 von vornherein ohne zusätzlichen Bremsstrom auslaufen zu lassen. Wenn die Drehzahl beziehungsweise die Umfangsgeschwindigkeit der Antriebstrommel 3 zum Zeitpunkt t3 einen vorgegebenen Wert v1 erreicht, wird die Antriebstrommel wieder beschleunigt und der Vorgang wiederholt sich.For reasons explained above, the image disturbance according to the invention is based on the representation of the peripheral velocities in Fig. 2 explained. The described evaluations are carried out by the controller 8 and the motor 7 is acted upon by the controller 8 with the corresponding current. The curve 10 represents the peripheral speed of the drive drum 3. In order to generate a slip between the drive drum 3 and the cheese 2, the drive drum is accelerated by a suitable engine torque. The acceleration starts at time t 0 . In Fig. 2 the increase in speed is linear. That is, in the acceleration phase, the engine torque is constant. But it is also possible to use a different curve. It is only important that the drive drum is accelerated. The curve 11, which represents the peripheral speed of the cheese 2 follows the curve 10 only delayed. The distance 12 between the curves 10 and 11 is the slip. If at time t 1, the drive drum 3 has reached a predetermined speed or a predetermined peripheral speed v 2 , the motor current is changed and the drive drum is acted upon by the motor 7 with a braking torque. Then the motor 7 is turned off. The existing friction moments ensure that the drum speed continues to decrease. In principle, it is also possible to let the drive drum 3 from the outset without additional braking current. When the rotational speed or the circumferential speed of the drive drum 3 reaches a predetermined value v 1 at time t 3 , the drive drum is accelerated again and the process is repeated.

Zum Zeitpunkt t1 hat die Trommeldrehzahl die obere Grenze erreicht und die Antriebstrommel wird abgebremst beziehungsweise verzögert. Die Kreuzspule 2 kann der Verzögerung jedoch nicht unmittelbar folgen. Die Drehzahl der Kreuzspule 2 steigt zunächst weiter an. Erst zum Zeitpunkt t2 erreicht die Drehzahl der Kreuzspule 2 ihr Maximum. In dem dargestellten Ausführungsbeispiel wird zum Zeitpunkt t2 gleichzeitig der Bremsstrom des Motors 7 abgeschaltet. So wird eine optimale Verzögerungsphase erreicht. Die Zeitdauer Δt mit Δt = t2 - t1 ist stark vom Schlupf abhängig, aber auch von anderen Parametern.At time t 1 , the drum speed has reached the upper limit and the drive drum is decelerated or decelerated. However, the cheese 2 can not follow the delay immediately. The speed of the cheese 2 initially continues to increase. Only at the time t 2 reaches the speed of the cheese 2 her Maximum. In the illustrated embodiment, the braking current of the motor 7 is switched off at the same time t 2 . This achieves an optimal deceleration phase. The time duration Δt with Δt = t 2 -t 1 depends strongly on the slip, but also on other parameters.

Um eine Größe zu erhalten, die ein eindeutiges Maß für den Schlupf darstellt, wird ein Quotient gebildet. Dieser Quotient kann durch Division der Zeitdauer Δt mit der Zeitdauer eines anderen Funktionsabschnittes gebildet werden. Als solche Zeitdauern kommen die Beschleunigungszeit t1 - t0, die Auslaufzeit t3 - t2 oder die Bildstörzykluszeit t3 - t0 in Frage. Es ist auch möglich, Summen der genannten Zeitdauern zu verwenden. So kann die Zeitdauer Δt durch die Summe aus Beschleunigungszeit und Auslaufzeit (t1-t0)+(t3-t2) geteilt werden.In order to obtain a size that represents a definite measure of the slip, a quotient is formed. This quotient can be formed by dividing the time duration Δt by the time duration of another functional section. As such time periods, the acceleration time t 1 - t 0 , the flow time t 3 - t 2 or the Bildstörzykluszeit t 3 - t 0 come into question. It is also possible to use sums of said time periods. Thus, the time period Δt can be divided by the sum of acceleration time and flow time (t 1 -t 0 ) + (t 3 -t 2 ).

Erfindungsgemäß wird ein Quotient der oben beschriebenen Art dazu verwendet, um den Schlupf optimal einzustellen. Dazu wird der Quotient mit einem oder mehreren Referenzwerten verglichen und in Abhängigkeit von dem Vergleich wird die Beschleunigungsphase der Antriebstrommel angepasst.According to the invention, a quotient of the type described above is used to optimally adjust the slip. For this purpose, the quotient is compared with one or more reference values and, depending on the comparison, the acceleration phase of the drive drum is adjusted.

Es ist möglich, entweder den Wert oder die Dauer der Beschleunigung anzupassen. Der Wert der Beschleunigung kann verändert werden, indem das Antriebsmoment des Motors 7, das heißt der Motorstrom, verändert wird. Dadurch wird die Steigung der Kurve 10 geändert. Die Dauer der Beschleunigung kann durch die Differenz Δv zwischen den Geschwindigkeiten v2 und v1 beeinflusst werden.It is possible to adjust either the value or the duration of the acceleration. The value of the acceleration can be changed by changing the drive torque of the motor 7, that is, the motor current. Thereby, the slope of the curve 10 is changed. The duration of the acceleration can be influenced by the difference Δv between the speeds v 2 and v 1 .

Im weiteren Verlauf der Auslaufphase gleichen sich die Umfangsgeschwindigkeiten von Antriebstrommel 3 und Kreuzspule 2 an. Das heißt, ab einem bestimmten Zeitpunkt tritt kein Schlupf mehr auf. Zu diesem Zeitpunkt kann in bekannter Weise aus den Drehzahlen von Antriebstrommel und Kreuzspule der aktuelle Durchmesser bestimmt werden.In the further course of the phase-out phase, the peripheral speeds of drive drum 3 and cross-wound bobbin 2 are equal. That is, at a certain time, no more slip occurs. At this time, the current diameter can be determined in a known manner from the rotational speeds of the drive drum and cross-wound bobbin.
