Description

Die Erfindung bezieht sich auf ein Verfahren zum Schären mit einer Konusschärmaschine, die Fäden bandweise auf eine Schärtrommel aufwickelt, bei dem ein Support für ein Fadenleitriet entsprechend der anwachsenden Wickeldicke und vorbestimmter Schärdaten relativ zur Schärtrommel von einen Vorschubantrieb parallel verschoben wird, wobei das erste Band während einer Meßphase von einer Walze unter Anpreßdruck abgetastet und der abgetastete Verstellweg in Abhängigkeit von der Anzahl der Umdrehungen der Schärtrommel registriert wird und wobei die Walze nach der Meßphase beim weiteren Aufwikkeln entsprechend einem mit der Meßphase gewonnenen Mittelwert zurückgenommen wird und auf den Wickel drückt.The invention relates to a method for warping with a cone warping machine, the threads on a band Winding up the warping drum, with a support for a thread guide according to the increasing winding thickness and predetermined Warping data relative to the warping drum from a feed drive is moved in parallel, the first volume scanned by a roller under contact pressure during a measurement phase and the scanned adjustment path depending on the number of revolutions of the warping drum is registered and the roller after the measuring phase during further winding according to an average obtained with the measurement phase is withdrawn and presses on the wrap.

Beim Schären wird eine Vielzahl von das Fadenleitriet passierenden und dadurch geführten Fäden bandweise auf die einen Stützkonus aufweisende Schärtrommel gewickelt. Das erste Fadenband wird mit einem durch den Konuswickel der Trommel bestimmten parallelogrammförmigen Querschnitt aufgewikkelt. Danach wird das zweite Band unter Ausnutzung der Stützwirkung des erstens Bands ebenfalls mit parallelogrammförmigen Querschnitt aufgewickelt. Entsprechende Vorgänge wiederholen sich für die nächstfolgenden Fadenbänder, bis die gesamte Fadenkette aufgewickelt ist. Der Aufbau aller Fadenbänder ist stark von den Eigenschaften der aufzuwickelnden Fäden abhängig, beispielsweise von deren Kapillaren, Färbung, Drehung, Spinnverfahren usw. Beim Wickeln ergeben sich zu harte oder zu weiche Wickel. Ergibt sich beispielsweise ein zu weicher Wickelaufbau des ersten Bandes, so arbeitet sich das zweite Band in die Flanke des ersten Bandes ein, das infolgedessen nicht hoch genug aufwächst. Seine Kettlänge ist kürzer, als die des ersten Bandes. Bei einem zu harten Wickelaufbau des ersten Bandes wird das zweite Band höher, da der Raum für das zweite Band durch die ausbeulende Flanke des ersten Bandes verkleinert wurde. Die Kettlänge ist dann größer, als die des ersten Bandes. Beides führt zu ungleichmäßigen verzogenen und gemusterten Geweben, die dementsprechend fehlerhaft sind.A large number of thread guides are used in warping passing and thereby guided threads in strips on the a warping drum having a supporting cone is wound. The first Thread band is with a through the cone winding of the drum certain parallelogram-shaped cross-section. After that, the second band is made use of the support effect the first band also with parallelogram Cross-section wound. Repeat the corresponding procedures up for the next thread straps until the entire Thread chain is wound. The construction of all thread bands is strong on the properties of the threads to be wound dependent, for example on their capillaries, color, rotation, Spinning processes etc. When winding, the result is too hard or too soft wraps. For example, if the result is too soft This is how it works second band into the flank of the first band, as a result not growing up high enough. Its warp length is shorter, than that of the first volume. If the winding structure is too hard of the first volume, the second volume increases because the Space for the second band through the bulging flank of the first volume was reduced. The warp length is then larger than that of the first volume. Both lead to uneven warped and patterned fabrics accordingly are faulty.

Aus der DE 26 31 573 C3 ist ein Verfahren mit den eingangs genannten Verfahrensschritten bekannt, bei dem das unter Druck erfolgende Messen während der Meßphase verwirklicht ist. Anschließend soll unter dem gleichen Druck das erste Band fertig kopiert und alle weiteren Bänder sollen unter Druck kopiert werden.DE 26 31 573 C3 describes a method with the above known process steps in which the under Pressure measurements carried out during the measurement phase is. Then the first should be under the same pressure The tape is copied and all other tapes should be under Print can be copied.

Aus der DE 34 32 276 A1 ist ein Schärverfahren bekannt, bei dem ein Vorschubantrieb mit einem einem Prozessor eingegebenen theoretisch errechneten Vorschub gesteuert wird. Zu Beginn des ersten Schärbandes wird eine Meßphase absolviert, nach der der entstandene Wickel kontrolliert und in Bezug auf seinen Sollzustand mit den im Prozessor gespeicherten Daten verglichen wird. Erforderlichenfalls wird eine Korrektur der Schärschlittenlage und des im Prozessor gespeicherten Programms vorgenommen, bedarfsweise auch mit einer zweiten Meßphase. Danach wird das erste Band fertiggeschärt und hierauf beim Schären aller folgenden Bänder die Vorschubbewegungen entsprechend denjenigen beim Schären des gesamten ersten Bandes gesteuert. Die gegebenenfalls erforderliche Korrektur erfolgt unter Zuhilfenahme eines Tasters, der von der Walze beaufschlagt wird und die Walzenstellung erfaßt.A warping method is known from DE 34 32 276 A1, in which a feed drive with a processor entered theoretically calculated feed is controlled. To A measuring phase is completed at the beginning of the first warping belt, after which the resulting wrap is checked and related its target state with the data stored in the processor is compared. If necessary, a correction of the Warping carriage position and the program stored in the processor made, if necessary also with a second measurement phase. After that, the first band is finished and then on when all subsequent belts are warmed, the feed movements corresponding to those in the warping of the entire first volume controlled. Any necessary correction is made with the help of a button that is acted upon by the roller is detected and the roller position.

In beiden vorbeschriebenen Verfahren wird während des Kopierens des ersten Bandes keine Überprüfung vorgenommen, ob der Wickelaufbau korrekt ist. Vielmehr muß die Meßphase so eingerichtet und durchgeführt werden, daß fehlerfreie Webketten aufgewickelt werden können.In both of the above procedures, during the Copy of the first volume no check made whether the winding structure is correct. Rather, the measurement phase must be like this be set up and carried out that flawless weaving chains can be wound up.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, ein Verfahren mit den eingangs genannten Merkmalen so zu verbessern, daß eine Einflußnahme auf den Wickelaufbau auch noch während des Kopierens des zumindest ersten Bandes ermöglicht wird.In contrast, the invention is based on the object to improve a method with the features mentioned at the beginning, that an influence on the winding structure also enabled during the copying of the at least first tape becomes.

Diese Aufgabe wird dadurch gelöst, daß der Druck der Walze auf den Wickel während der Meßphase und/oder beim weiteren Aufwickeln bzw. Kopieren fortlaufend meßtechnisch überwacht wird und im Falle einer Abweichung des Überwachungsergebnisses von einem vorbestimmten Sollwert eine Korrektur des Supportvorschubs erfolgt.This object is achieved in that the pressure of the Roll on the reel during the measuring phase and / or during the further Rewinding or copying continuously monitored by measuring technology and in the event of a deviation in the monitoring result a correction of the predetermined setpoint Support feeds are made.

Durch ein solches Verfahren wird erreicht, daß ein Eingriff in den Aufbau des Wickels auch noch während des Kopierens möglich ist. Entspricht der effektiv vorhandene Druck nicht dem Solldruck unter Berücksichtigung von Toleranzschwellen, so kann eine Reaktion ausgelöst werden, die beispielsweise in einer Korrektur des Supportvorschubs besteht. Der Supportvorschub kann also verringert bzw. unterbrochen oder vergrößert werden. Dies hat eine verringerte bzw. vergrößerte Wickeldickenzunahme zur Folge, so daß der Wickelaufbau auch noch während des Kopierens korrigierend vergleichmäßigt werden kann. Es ist eine komplette Ausregelung des Drucks der Walze während des gesamten Wickelaufbaus möglich. Infolgedessen ist es möglich, Einflüsse auszuschalten, die während einer Meßphase oder auch mehrerer Meβphasen nicht erfaßt werden können, beispielsweise die Zunahme der Fadenspannung infolge abnehmenden Fadenvorrats der Spulen des Spulengatters oder nicht genauer Eingabeparameter, deren Abweichungen zu einem Multiplikationseffekt bei länger werdenden Ketten führen.Such a procedure ensures that an intervention in the build-up of the wrap even while copying is possible. Corresponds to the effectively existing pressure not the target pressure considering tolerance thresholds, a reaction can be triggered, for example consists of a correction of the support advance. The support feed can therefore be reduced or interrupted or be enlarged. This has decreased or increased Increase in winding thickness, so that the winding structure corrected even during copying can be. It is a complete adjustment of the Pressure of the roller possible during the entire winding build-up. As a result, it is possible to eliminate influences that not recorded during a measurement phase or even several measurement phases can be, for example, the increase in thread tension due to decreasing thread supply of the bobbin creel or not more precise input parameters, their deviations to a multiplication effect with longer chains to lead.

Das bezüglich der Meßphase beschriebene Verfahren kann so durchgeführt werden, daß die Meßphase mit einem Druck-Sollwert gestartet wird, der in Abhängigkeit von Kenngrößen der aufzuwickelnden Fäden ausgewählt wird. Es erfolgt eine Anpassung des Wickelvorgangs an das Verhalten der aufzuwikkelnden Fäden, das z.B. durch die Anzahl der Kapillaren, durch die Färbung, durch die Drehung oder durch das Spinnverfahren bestimmt wird. Diese Anpassung ist von Bedeutung, weil bereits kleine Abweichungen dieses artikelspezifischen Druck-Sollwerts zu Fehlern bei der Bildung des Mittelwerts führen, der aufgrund der registrierten Meßwerte während der Meßphase gewonnen wird. Solche Fehler können sich erheblich auswirken, weil die großen Kettlängen einen entsprechenden Multiplikationseffekt bewirken.The method described with regard to the measurement phase can be carried out so that the measurement phase with a pressure setpoint is started, depending on parameters of the threads to be wound is selected. There is a Adaptation of the winding process to the behavior of those to be wound up Threads that e.g. by the number of capillaries, by coloring, by turning or by spinning is determined. This adjustment is important because even small deviations from this article-specific pressure setpoint lead to errors in the averaging, based on the registered measured values during the measuring phase is won. Such mistakes can have a significant impact because the large warp lengths have a corresponding multiplication effect cause.

Das bezüglich der Meßphase beschriebene Verfahren kann aber auch so durchgeführt werden, daß für die Meßphase ein Vorschub bestimmt wird, dessen Größe von Kenngrößen der aufzuwickelnden Fäden ausgewählt wird. Eine derartige Bestimmung des Vorschubs, der also errechnet ist, führt zu einer relativen Verschiebung der Schärtrommel nicht nur unter Berücksichtigung des Konuswinkels, sondern zusätzlich auch unter Berücksichtigung der Kenngrößen der aufzuwickelnden Fäden. Ein solches Verfahren ist insbesondere dann notwendig, wenn der Druck der Walze während der Meßphase praktisch Null sein soll oder lediglich beim Kopieren eine meßtechnische Überwachung erfolgt. Die Anwendung eines errechneten Vorschubs während der Meßphase kann aber auch in Ergänzung zur Überwachung des Drucks der Walze auf den Wickel während der Meßphase angewendet werden, wobei der errechnete Vorschub in der Meßphase mittels des Drucksensors verändert wird, so daß nach Abschluß der Meßphase wieder ein korrekter Vorschub entsteht.The method described with regard to the measurement phase can but also be carried out so that for the measurement phase Feed is determined, the size of which is to be wound up by parameters Threads is selected. Such a provision of the feed, which is thus calculated, leads to a relative one Shifting the warping drum not only taking into account of the cone angle, but also taking into account the parameters of the threads to be wound. On Such a procedure is particularly necessary if the Pressure of the roller should be practically zero during the measuring phase or only a metrological monitoring when copying he follows. The application of a calculated feed during the measurement phase can also be used in addition to monitoring the Pressure of the roller applied to the roll during the measuring phase be, the calculated feed in the measuring phase is changed by means of the pressure sensor, so that after completion a correct feed occurs again during the measuring phase.

Zur Einflußnahme auf den gesamten Schärwickel ist es vorteilhaft, das Verfahren so durchzuführen, daß die Korrektur des Supportvorschubs auch beim Kopieren von auf das erste Band folgenden Bändern erfolgt. Es wird erreicht, daß auch vom Konus entfernt geschärte Bänder in ihrem Aufbau gleichmäßig zum Wickelaufbau des ersten Bandes sind.It is to influence the entire warp winding advantageous to carry out the method so that the correction of the support advance even when copying from the first Tape following tapes is done. It is achieved that too The structure of sharpened bands removed from the cone is even to build up the first tape.

Das Verfahren kann so durchgeführt werden, daß die Korrektur des Supportvorschubs im Falle einer Druckzunahme oder einer Druckabnahme schrittweise über die Trommeldrehung verteilt erfolgt. Damit ergibt sich die Möglichkeit, entsprechenden Einfluß auf den Wickelaufbau zu nehmen, nämlich im Sinne einer Vergleichmäßigung über den Umfang gesehen. Es ist beispielsweise möglich, größere Druckzunahmen nicht schlagartig abbauen zu müssen. Plötzliche Druckzunahmen im Sinne von Druckspitzen ergeben sich beispielsweise im Einhängbereich der Fäden an der Konustrommel. Das ist in gewissem Umfang auch dann der Fall, wenn die Einhängstellen in der Konustrommel versenkt sind.The procedure can be carried out so that the correction the support advance in the event of an increase in pressure or a decrease in pressure gradually distributed over the drum rotation he follows. This results in the possibility of corresponding To influence the winding structure, namely in Seen a leveling out of the scope. It is for example, it is not possible for larger pressure increases to occur suddenly to dismantle. Sudden pressure increases in the sense of Pressure peaks occur, for example, in the hanging area the threads on the cone drum. To some extent, that is also the case if the hanging points in the cone drum are sunk.

Es kann auch von Vorteil sein, das Verfahren so durchzuführen, daß kurzzeitig auftretende Druckänderungen während der Meßphase und/oder während des Kopierens bei der Gewinnung des Mittelwerts und/oder bei dem Überwachen des Drucks unberücksichtigt bleiben. Im Fall derartiger kurzzeitiger Druckänderungen kann davon ausgegangen werden, daß sich keine gravierenden Änderungen des Wickelaufbaus ergeben werden. Sofern also auftretende Druckänderungen eine vorgegebene Zeit nicht überschreiten, erfolgt keine Korrektur des Supportvorschubs. Ein derartiges Verfahren findet praktischerweise statt, wenn querliegende Schnüre eingewickelt werden müssen, oder wenn durch das Einhängen bedingte Verdichtungen des Bandes auftreten, die dann jeweils ausgeblendet werden.It can also be advantageous to carry out the method in such a way that briefly occurring pressure changes during the measuring phase and / or during copying during extraction of the mean and / or not taken into account when monitoring the pressure stay. In the event of such brief pressure changes can be assumed that no serious Changes in the winding structure will result. Provided therefore, pressure changes that occur do not occur for a predetermined time the support advance will not be corrected. Such a procedure conveniently takes place when transverse cords need to be wrapped, or if the belt is compressed due to the hanging, which are then hidden.

Das Verfahren kann so durchgeführt werden, daß die während der Meßphase auftretenden Vorschubveränderungen bzw. Lageänderungen des Supports, die in Abhängigkeit von der Anzahl der Umdrehungen der Schärtrommel erfaßt wurden, in Folgebändern kopiert werden. Infolgedessen werden Änderungen des Wikkelaufbaus während der Meßphase des ersten Bandes in die der Meßphase des ersten Bandes entsprechenden Anfangsbereiche der Folgebänder übernommen, so daß hier jeweils Gleichförmigkeit des Wickelaufbaus vorliegt.The process can be carried out so that the during changes in feed or changes in position occurring during the measuring phase of support depending on the number of the revolutions of the warping drum were recorded in subsequent belts be copied. As a result, changes in winding construction during the measurement phase of the first volume in the Measuring phase of the first volume corresponding initial areas of the Subsequent tapes taken over, so that here in each case uniformity of the winding structure is present.

Es kann vorteilhaft sein, das Verfahren so durchzuführen, daß das erste Band mit konstanter Fadenzugkraft aufgewickelt wird, und beim Kopieren ab dem zweiten Band eine Beeinflussung der Fadenzugkraft der aufgewickelten Fäden anstelle oder in Ergänzung einer Korrektur des Supportvorschubs erfolgt. Änderungen der Fadenzugkraft helfen, Vorschubkorrekturen zu vermeiden. Sie können sie vollständig ersetzen, falls Druckänderungen durch die Walze unerwünscht sind.It can be advantageous to carry out the method in such a way that the first tape is wound with constant thread tension and an influence when copying from the second volume the thread tension of the wound threads instead or in addition to a correction of the support feed he follows. Changes in thread tension help feed corrections to avoid. You can completely replace them if pressure changes through the roller are undesirable.

Die Erfindung bezieht sich auch auf eine Konusschärmaschine, mit einem ein Fadenleitriet tragenden Support, der an einem Maschinengestell parallel zu einer Schärtrommel verstellbar ist, mit einem von einer Steuereinrichtung steuerbaren motorischen Vorschubantrieb zur Erzeugung von dem Wickeldickenzuwachs entsprechenden Relativbewegungen zwischen der Schärtrommel und dem Support, mit einer den Wickelumfang mit Druck abtastenden Walze, deren Verstellweg in Abhängigkeit von der Anzahl der Umdrehungen der Schärtrommel mit der Steuereinrichtung speicherbar ist.The invention also relates to a cone warping machine, with a support carrying a thread guide, the a machine frame adjustable parallel to a warping drum is, with a controllable by a control device Motorized feed drive for the generation of the winding thickness increase corresponding relative movements between the Warping drum and the support, with one with the winding circumference Pressure-sensing roller, the adjustment path depending on the number of revolutions of the warping drum with the control device is storable.

Um die vorbeschriebenen Verfahren durchführen zu können, wird die Konusmaschine so ausgebildet, daß die Walze an mindestens einem Drucksensor abgestützt ist, der die Steuereinrichtung während der Meßphase und/oder beim weiteren Aufwikkeln bzw. Kopieren beaufschlagt, welche die Walze im Falle eines Abweichens des gemessenen Drucks von einem vorbestimmten Sollwert im Korrektursinn steuert. Die von dem Wickel beaufschlagte Walze vermag in einfacher Weise einen Drucksensor zu beaufschlagen, dessen Meßwert von der Steuereinrichtung ausgewertet werden kann. Solche Drucksensoren können sowohl überschüssigen Druck erfassen, als auch Minderdruck. Zur Korrektur des Drucks der Walze auf den Wickel kann die Steuereinrichtung nach den bei Regelkreisen allgemein bekannten Kriterien ausgelegt werden. Es ist nicht erforderlich, besondere Stelleinrichtungen einzusetzen, die zusätzlich zu den ohnehin benötigten Stelleinrichtungen sind.In order to be able to carry out the procedures described above, the cone machine is designed so that the roller at least a pressure sensor is supported, which the control device during the measuring phase and / or during further winding or copied, which the roller in the case a deviation of the measured pressure from a predetermined one Controls setpoint in the direction of correction. The one impacted by the wrap The roller can easily handle a pressure sensor to apply, the measured value of the control device can be evaluated. Such pressure sensors can both record excess pressure as well as low pressure. For correction the control device can apply the pressure of the roller to the reel according to those generally known in control loops Criteria are interpreted. It is not required to be special Use actuators that in addition to Actuators required anyway.

Die Konusschärmaschine ist dahingehend ausgestaltet werden, daß die Walze mit einem Servomotor gegen den Wickel gedrückt wird. Infolgedessen entfallen Bauteile, die benötigt wurden, um die Verstellung der Walze in Abhängigkeit vom Vorschubantrieb des Supports zu bewerkstelligen. Beispielsweise entfallen ein Getriebe, die Kupplungen und Spindelbauteile. Der im Support eingebaute Servomotor wird aktiv, wenn der Istdruck der Regelwalze vom Solldruck abweicht. Der Servomotor verstellt dann, z.B. bei zu hohem Druck, den Support achsparallel. Über eine der Konussteigung entsprechende Übersetzung wird der Support gleichzeitig senkrecht zur Schärtrommelachse verstellt.The cone warping machine is designed for this purpose be that the roller with a servo motor against the winding is pressed. As a result, components that are needed are eliminated were used to adjust the roller depending on the feed drive of support. For example there is no need for a gearbox, the couplings and spindle components. The servo motor built into the support becomes active when the Actual pressure of the regulating roller deviates from the target pressure. The servo motor then adjusts e.g. if the pressure is too high, support axially parallel. Via a translation corresponding to the congestion the support becomes perpendicular to the warping drum axis adjusted.

Wenn die Walze an einem Schwenkarm gelagert ist, kann der Drucksensor weitgehend unabhängig vom dem elastischen Verhalten der Walze eingesetzt werden, was sich vorteilhaft auf die Genauigkeit der Messung auswirkt.If the roller is mounted on a swivel arm, can the pressure sensor largely independent of the elastic Behavior of the roller can be used, which is advantageous affects the accuracy of the measurement.

Eine Konusschärmaschine weist als wesentlichen Bestandteil eine Schärtrommel 11 auf, die von einem nicht dargestellten Schärtrommelantrieb drehbar ist. An ihrem einen Ende besitzt die Schärtrommel 11 einen aus den Fig. 1,3 ersichtlichen Konus 19, welcher der Abstützung der bandweise aufgewikkelten Fäden 10 dient, die der Konusschärmaschine von den Spulen eines nicht dargestellten Spulengatters zulaufen. Die Fäden 10 bilden eine Fadenschar, die durch ein Fadenleitriet 13 auf Bandbreite geordnet sind und über eine Meßwalze 20 geführt werden. Die Meßwalze 20 wird von der Fadenschar 10 gedreht, so daß es möglich ist, die Fadenlänge zu messen. Von der Meßwalze 20 gelangt die Fadenschar unter teilweiser Umschlingung einer Umlenkwalze 21 zur Schärtrommel 11. Die Fäden 10 der Fadenschar werden bündelweise verknotet und an nicht dargestellen Einhängvorrichtungen der Trommel 11 befestigt. Die drehangetriebene Schärtrommel 11 zieht dann die Fäden 10 von den Spulen des Spulengatters ab und wickelt sie auf.A cone warping machine has an essential component a warping drum 11 by one, not shown Warping drum drive is rotatable. At one end the warping drum 11 has one that can be seen in FIG. 1.3 Cone 19, which the support of the tapes wound up Threads 10 is used by the cone warping machine Coils of a creel, not shown, run in. The Threads 10 form a thread sheet which is guided by a thread guide 13 are arranged on bandwidth and guided over a measuring roller 20 become. The measuring roller 20 is rotated by the thread sheet 10, so that it is possible to measure the thread length. Of the measuring roller 20 passes the thread sheet with partial wrap a guide roller 21 to the warping drum 11. The threads 10 of the thread cluster are knotted in bundles and attached Not shown hangers of the drum 11 attached. The rotary driven warping drum 11 then pulls the Threads 10 from the bobbin of the creel and winds them on.

Das Aufwickeln der Fäden 10 erfolgt bandweise gemäß Fig. 3. Die Fäden eines Bandes werden in vielen Lagen übereinander gewickelt, wobei sich ein parallelogrammförmiger Querschnitt der Bänder ergibt, z.B. des Bandes 14. Wird dieser Querschnitt erreicht, ist das erste Band 14 von dem Konus 19 der Schärtrommel in deren axialer Richtung abgestützt. Um den aus Fig.3 ersichtlichen parallelogrammförmigen Querschnitt des ersten Bands 14 zu erreichen, müssen die Aufwickelstellen der Fäden auf die Schärtrommel 11 bzw. auf die bewickelten Fadenlagen axial verlagert werden. Dies geschieht durch entsprechende Relativbewegungen zwischen der Schärtrommel 11 und einem das Schärriet 13 bzw. die Meßwalze 20 und die Umlenkwalze 21 tragenden Support 12. Diese schärtrommelachsparallele Relativbewegung ist der sogenannte Supportvorschub, der beispielsweise durch einen nicht dargestellten Vorschubantrieb erzeugt wird, beispielsweise durch einen Servomotor, der supportfest ist und in eine Bodenschiene oder in eine zahnschiene des in Fig.1 schematisch dargestellten ortsfesten Maschinengestells 17 eingreift.The threads 10 are wound up in strips according to FIG. 3. The threads of a tape are superimposed in many layers wound, with a parallelogram cross-section the bands result, e.g. of volume 14. This cross section reached, the first band 14 of the cone 19 of the The warping drum is supported in its axial direction. To the out 3 shows parallelogram-shaped cross section of the To reach the first bands 14, the take-up points of the Threads on the warping drum 11 or on the wound thread layers be axially displaced. This is done by appropriate Relative movements between the warping drum 11 and one the Schärriet 13 or the measuring roller 20 and the deflection roller 21 supporting support 12. This relative movement parallel to the warping drum is the so-called support feed, for example by a feed drive, not shown is generated, for example by a servo motor that is support-resistant and in a floor rail or a tooth rail of the stationary machine frame shown schematically in Fig.1 17 engages.

Der Supportvorschub erfolgt unter Berücksichtigung des Konuswinkels und proportional der beim Aufwickeln anwachsenden Wickeldicke. Während der Konuswinkel eine fixe Größe ist und bei der Bestimmung des Supportvorschubs entsprechend berücksichtigt wird, muß die anwachsende Wickeldicke meßtechnisch erfaßt werden. Das geschieht mit einer Regelwalze 15, die praktisch bandbreit ist und am Support 12 drehbar lagert. Die Regelwalze 15 wird zu Wickelbeginn an der Schärtrommel 11 angestellt, wobei der Konusanfang 19' die Ausgangs- oder Nullstellung bestimmt. Entsprechend den Fadenspezifika baut sich der Wickel 16 schneller oder langsamer auf und muß dementsprechend der Supportvorschub größer oder kleiner sein. Ist das Garn beispielsweise dick, nimmt die Wickeldicke schneller zu und der Vorschub bzw. die axiale Verstellung der Regelwalze 15 in mm je Winkelgrad bzw. je Trommelumdrehung muß größer sein.The support feed takes into account the Cone angle and proportional to the increase during winding Winding thickness. While the cone angle is a fixed size and taken into account accordingly when determining the support advance , the increasing winding thickness must be measured be recorded. This is done with a regulating roller 15, which is practically bandwidth and rotatably mounted on the support 12. The regulating roller 15 is on the warping drum 11 at the start of winding employed, the cone beginning 19 'the output or Zero position determined. Builds according to the thread specifics the winding 16 moves faster or slower and must accordingly the support feed may be larger or smaller. For example, if the yarn is thick, the winding thickness increases faster and the feed or the axial adjustment of the Guide roller 15 in mm per degree of angle or per drum revolution must be bigger.

Die Regelwalze 15 ist in nicht dargestellter Weise senkrecht zur Achse der Trommel 11 verstellbar und wird vor Wikkelbeginn gegen die Schärtrommel verfahren. Wenn die Schärtrommel 11 gedreht wird, baut sich der Wickel 16 lagenweise auf. Zu Beginn des Aufwickelns des ersten Bandes 14 wird eine Meßphase 23 durchgeführt, die sich beispielsweise über 100 Umdrehungen der Schärtrommel 11 erstreckt. Während der Meßphase 23 wird also das Band unter Anpreßdruck abgetastet und bei einer Überschreitung des Solldrucks wird mittels des Servomotors eine achsparallele Bewegung und gleichzeitig eine radiale Bewegung solange ausgelöst, und zwar in kleinen Schritten, bis der Solldruck wieder vorhanden ist. Nach Ablauf der Meßphase 23 wird ein Mittelwert bestimmt, also der mittlere Verstellweg je Schärtrommelumdrehung und damit ein mittlerer Vorschub. Diesem entspricht der Vorschub, der während des der Meßphase 23 nachfolgenden Kopierens angewendet wird.The regulating roller 15 is vertical in a manner not shown adjustable to the axis of the drum 11 and is before winding start move against the warping drum. If the warping drum 11 is rotated, the winding 16 builds up in layers on. At the beginning of the winding of the first tape 14, a Measurement phase 23 carried out, for example, over 100 Rotations of the warping drum 11 extends. During the measurement phase 23 so the tape is scanned under contact pressure and if the set pressure is exceeded, the servo motor an axis-parallel movement and at the same time one radial movement triggered as long, and in small Steps until the set pressure is available again. After expiration the measurement phase 23 an average value is determined, that is average adjustment path per warp drum revolution and thus one medium feed. This corresponds to the feed rate during of the copying following the measuring phase 23 applied becomes.

Die Meßphase 23 erstreckt sich nur über eine vergleichsweise geringe Wickeldicke. Es ist daher möglich, daß die Messung nicht genau genug ist, und daß sich im Laufe des weiteren Aufwickelns des ersten Bandes Änderungen des Drucks der Regelwalze 15 auf den Wickel 16 ergeben. Die Folge wäre ein falscher Wickelaufbau. Es ist daher vorgesehen, den Druck der Regelwalze 15 auf den Wickel 16 zu kontrollieren.The measurement phase 23 extends only over a comparatively low winding thickness. It is therefore possible that the measurement is not accurate enough, and that in the course of the further Winding up the first tape changes the pressure of the Rule roller 15 on the roll 16 result. The consequence would be one wrong winding structure. It is therefore intended to reduce the pressure of the Control roller 15 on the reel 16.

Zum Messen des Drucks der Regelwalze 15 auf den Wickel 16 des Bandes 14 ist die Walze am Support 12 angelenkt. Die Anlenkung erfolgt mit einem Schwenkarm 39 an jedem Ende der Regelwalze 15, der Relativbewegungen zum Support 12 zuläßt. Jeder Schwenkarm 19 lagert ein Ende 15' einer Regelwalzenachse der Regelwalze 15 mit einem Lager 23. An dem Lager 23 ist ein Druckstift 18' eines Drucksensors 18 abgestützt, der seinerseits maschinengestellfest ist. Verlagerungen der Regelwalze 15 bzw. des Schwenkarms 39 führen daher zu einer Verstellung des Druckstifts 18' und infolgedessen zu einem Meßwert des Drucksensors 18. Die Einstellung des Drucks der Regelwalze 15 auf den Wickel 16 erfolgt also dadurch, daß die Regelwalze 15 mit dem Support 12 solange gegen die Schärtrommel 11 geschoben wird, bis der vorbestimmte Druck erreicht wird. Da der Meßwert des Drucksensors kontinuierlich zur Verfügung steht, ist es möglich, ihn kontinuierlich zu überwachen und bedarfsweise zu verändern. Das kann während des Schärens des ersten Bandes beispielsweise dadurch geschehen, daß der Supportvorschub innerhalb des Kopiervorgangs korrigiert wird.For measuring the pressure of the regulating roller 15 on the reel 16 of the belt 14, the roller is articulated on the support 12. The Articulation takes place with a swivel arm 39 at each end of the Guide roller 15, which allows relative movements to support 12. Each swivel arm 19 supports one end 15 'of a control roller axis the regulating roller 15 with a bearing 23. At the bearing 23 a pressure pin 18 'of a pressure sensor 18 is supported, which in turn is fixed to the machine frame. Shift of the regulating roller 15 and the swivel arm 39 therefore lead to an adjustment of the push pin 18 'and consequently to a measured value of the pressure sensor 18. Adjustment of the pressure of the regulating roller 15 on the winding 16 is done in that the Regulating roller 15 with the support 12 against the warping drum 11 is pushed until the predetermined pressure is reached becomes. Because the measured value of the pressure sensor is continuously available it is possible to monitor it continuously and change if necessary. This can happen during the The first band is warmed, for example, by that the support advance is corrected within the copying process becomes.

Das Verfahren während der Meßphase 23 wird anhand von Fig.4 erläutert. Fig.4 zeigt den Drucksensor 18 als Block, der sein Meßergebnis einer Regeleinrichtung 27 zuleitet. In der Regeleinrichtung 27 ist der Verlauf v1 dieses Drucks in Abhängigkeit von der Zeit beispielsweise schematisch dargestellt. Der Druck v1 schwankt um einen Mittelwert v2, der als fadenspezifischer Druck von einem Datenspeicher 27' der Regeleinrichtung 27 vorgegeben ist. Für v2 ist ein Toleranzfeld vorgegeben, das in der Regeleinrichtung 27 durch ein Minuszeichen und ein Pluszeichen gekennzeichnet ist. Bewegt sich der vom Drucksensor 18 gelieferte Meßwert v1 innerhalb dieser Toleranzgrenzen, ist eine Lageänderung des Supports nicht nötig. Überschreitet das Meßergebnis des Drucksensors 18 die Toleranzschwelle der Regeleinrichtung 27, so erfolgt ein Signal an die Steuereinrichtung 24. Von dort wird der Servomotor 25 betätigt, der dann den Support 12 verstellt. Der Drucksensor 18 überschreitet die Toleranzschwelle der Regeleinrichtung 27 fast permanent, falls kein Vorschub vorgegeben ist und erst in der Meßphase ein Vorschub ermittelt wird. Die Steuereinrichtung 24 beaufschlagt einen Speicher 29 für die Meßphase mit dem Vorschub je Umdrehung der Schärtrommel 11. In der Steuereinrichtung 24 sind auch die Daten zur Wickelgeschwindigkeit, zur Kettlänge, zur Bandbreite, zur Anzahl der zu wickelnden Bänder und zur Fadenzugkraft abgelegt. The method during the measurement phase 23 is based on Fig.4 explained. 4 shows the pressure sensor 18 as a block, which forwards its measurement result to a control device 27. In of the control device 27 is the curve v1 of this pressure in Depicted schematically for example as a function of time. The pressure v1 fluctuates around an average value v2, which as thread-specific printing from a data memory 27 'of the control device 27 is specified. There is a tolerance zone for v2 specified in the control device 27 by a minus sign and a plus sign is marked. Is moving the measured value v1 supplied by the pressure sensor 18 within this Tolerance limits, it is not necessary to change the position of the support. If the measurement result of the pressure sensor 18 exceeds the Tolerance threshold of the control device 27, a signal is issued to the control device 24. From there the servo motor 25 actuated, which then adjusts the support 12. The pressure sensor 18 exceeds the tolerance threshold of the control device 27 almost permanent if no feed is specified and a feed is only determined in the measuring phase. The Control device 24 acts on a memory 29 for the Measuring phase with the feed per revolution of the warping drum 11. The control device 24 also contains the data on the winding speed, to warp length, to bandwidth, to the number of to be wound tapes and thread tension.

In Fig.5 wird das Verfahren beim weiteren Aufwickeln des ersten Bandes nach der Meßphase erläutert. Die Regeleinrichtung 27 gibt den gemittelten Vorschub aus der Meßphase kontinuierlich an die Steuereinrichtung 24 weiter. Von dort wird der Servomotor 25 betätigt, der wiederum den Support 12 verschiebt. Der Drucksensor 18 übermittelt fortlaufend Meßwerte v1 an die Regeleinrichtung 27. Sobald diese Werte v1 den aus dem Datenspeicher 27' übermittelten fadenspezifischen Druck in der +/--Toleranzschwelle über- oder unterschreiten, wird der gemittelte Vorschub aus der Meßphase solange verändert, bis v1 wieder innerhalb der Toleranzschwellen von v2 verläuft. Die Korrektur des Supportvorschubs erfolgt direkt über die Steuereinrichtung 24' auf den Servomotor 25. Die Steuereinrichtung 24 veranlaßt, daß der neue Vorschub in einem Speicher 30 für die Kopierphase des ersten Bandes abgespeichert wird. Derartige Korrekturen werden bedarfsweise wiederholt durchgeführt. Fig.3 zeigt Kopierphasen 32, in denen jeweils Vorschubänderungen erfolgen, falls der in der Meßphase 23 ermittelte Vorschub nicht geeignet ist, die Walze 15 im Toleranzfeld von v2 zu halten.In Fig.5, the method is further winding the first volume after the measurement phase. The control device 27 gives the averaged feed from the measuring phase continuously to the control device 24. From there the servo motor 25 is actuated, which in turn shifts the support 12. The pressure sensor 18 continuously transmits measured values v1 to the control device 27. As soon as these values v1 from thread-specific pressure transmitted to the data memory 27 ' in the + / - tolerance threshold will be exceeded the averaged feed from the measuring phase is changed as long as until v1 again runs within the tolerance thresholds of v2. The correction of the support advance is made directly via the control device 24 'on the servo motor 25. The control device 24 causes the new feed in one Memory 30 is stored for the copying phase of the first tape becomes. Such corrections are repeated as necessary carried out. 3 shows copying phases 32, in each of which Feed changes are made, if in the measuring phase 23 determined feed is not suitable, the roller 15 in Keep tolerance of v2.

In Fig.3 wird an der rechten Flanke des ersten Bandes 14 dargestellt, daß diese Flanke während der Meßphase 23 nicht ideal glatt ist. Es ergibt sich eine Abstufung, auf die verfahrensmäßig kein Einfluß genommen ist, abgesehen von dem Druck der Regelwalze 15. Die Abstufung kommt dadurch zustande, daß sich bei Wickelbeginn sofort ein Druck aufbaut und die Minustoleranzschwelle der Regeleinrichtung 27 überschritten wird. Das ist jedenfalls dann der Fall, wenn kein Vorschub vorgegeben ist. An die Meßphase schließt sich eine Kopierphase 32 an, während der die Regelwalze 15 entsprechend v2 oder entsprechend dem während der Meßphase 23 gewonnenen, nicht dargestellten Mittelwert v2' zurückgenommen wird und dabei entsprechend auf den Wickel 16 drückt. Es ergibt sich eine feinere Abstufung der rechten Flanke des ersten Bandes, die durch einen geraden Flankenabschnitt 33 dargestellt wurde. Sollte sich im Verlauf des weiteren Aufwickels bzw. Kopierens die Notwendigkeit einer Änderung des Anpreßdrucks ergeben, so erfolgt eine Korrektur des Supportvorschubs. Es ergeben sich wiederum Abstufungen, die ähnlich denen in der Meßphase sind und die als Einzelheit A vergrößert dargestellt wurden. In dem Speicher 30 kann das Anwachsen der Wickeldicke des gesamten ersten Bandes 14 oberhalb des in der Meßphase 23 gewickelten Anteils in Abhängigkeit von der Anzahl der Trommelundrehungen abgespeichert sein.3 shows 14 on the right flank of the first band shown that this edge is not during the measurement phase 23 is ideally smooth. There is a gradation on the procedural no influence apart from that Pressure of the regulating roller 15. The gradation occurs because that a pressure builds up immediately at the start of winding and the minus tolerance threshold of the control device 27 is exceeded becomes. In any case, this is the case when there is no feed is specified. A copying phase follows the measuring phase 32, during which the regulating roller 15 accordingly v2 or corresponding to that obtained during the measurement phase 23, mean value v2 ', not shown, is withdrawn and presses accordingly on the winding 16. It follows a finer gradation of the right flank of the first volume, which was represented by a straight flank section 33. Should change in the course of further winding or copying result in the need to change the contact pressure, so the support advance is corrected. Surrender it turn, gradations similar to those in the Measurement phase and are shown enlarged as detail A. were. In the memory 30, the increase in the winding thickness can of the entire first band 14 above that in the measuring phase 23 wound portion depending on the number of drum revolutions be saved.

Nach dem Kopieren des ersten Bandes 14 erfolgt das Kopieren des zweiten Bandes 15, was in Fig.6 erläutert wird. Der Supportvorschub wird von den Speichern 29,30 gesteuert. Der Speicher 29 steuert den Supportvorschub exakt so, wie dieser für die Meßphase 23 des ersten Bandes aufgezeichnet und abgespeichert wurde. Danach übernimmt der Speicher 30 die Steuerung des Supportvorschubs über das Steuergerät 24 und den Servomotor 25. Dementsprechend ergeben sich im zweiten Band 15 Änderungen des Supportvorschubs, wie sie beim weiteren Aufwickeln des ersten Bandes 14 nach der Meßphase 23 festgehalten wurden. Auch die weiteren Bänder werden entsprechend geschärt, also sowohl entsprechend den Werten der in der Meßphase 23 aufgetretenen Druckänderungen, als auch entsprechend den während der Kopierphase des ersten Bands aufgetretenen Vorschubänderungen in den Änderungsphasen 31.After the first tape 14 has been copied, the copying takes place of the second band 15, which is explained in Fig.6. The support feed is controlled by the memories 29.30. The memory 29 controls the support feed exactly as this is recorded for the measurement phase 23 of the first tape and saved. Then the memory 30 takes over Control of the support feed via the control unit 24 and the servo motor 25. Accordingly, in the second Volume 15 Changes in the support feed, as in the further Winding up the first tape 14 after the measurement phase 23 were detained. The other tapes are also corresponding sharpened, both according to the values of in the pressure phase 23 occurring pressure changes, as well as accordingly those that occurred during the copy phase of the first tape Feed changes in the change phases 31.

Es ist durchaus möglich, daß insbesondere während der Meßphase 23 Druckspitzen auftreten, mit denen das Toleranzfeld von v1 verlassen wird. Solche Druckspitzen entstehen beispielsweise durch eingelegte Teilschnüre oder durch Vertiefungen im Trommelumfang, die zum Einhängen von Fadenbündeln bestimmt sind. Da diese Druckspitzen, also positive oder negative, nur kurzzeitig auftreten, sollten sie nicht zu einer Korrektur des Supportvorschubs beitragen. Sie können daher von der Steuereinrichtung 24 ausgeblendet werden und gelangen nicht z.B. in den Speicher 29. Während der Meßphase bleibt sie also bei der Ermittlung des Mittelwerts unberücksichtigt und während der Kopierphase bleiben sie beim Überwachen des Drucks unberücksichtigt.It is quite possible that especially during the Measuring phase 23 pressure peaks occur with which the tolerance field is left by v1. Such pressure peaks arise for example, through inserted partial cords or through depressions in the circumference of the drum, for hanging thread bundles are determined. Because these pressure peaks, i.e. positive or negative, occur only briefly, they should not become one Correct the support advance. So you can are hidden by the control device 24 and arrive not e.g. into memory 29. During the measurement phase it is therefore not taken into account when determining the mean and during the copying phase they stay on monitoring the pressure is not taken into account.

In Fig.3 ist außer dem ersten Band 14 auch ein zweites Band 15 dargestellt. Dieses zweite Band 15 und etwaige weitere Bänder werden dem ersten Band 14 entsprechend kopiert. Es entstehen also Bänder mit Wickelanteilen 23', die wie in der Meßphase 23 aufgebaut sind. Bis zur Fertigstellung des kompletten zweiten Bandes 15 wird dann ebenso gewickelt, wie der Rest des ersten Bandes nach der Meßphase 23. Auch beim Kopieren des Bandes 15 und etwaiger weiterer Bänder kann eine Drucküberwachung erfolgen. Es ergeben sich zusätzliche, nicht dargestellte Änderungsphasen 31 im zweiten Band 15, die in die folgenden Bänder übernommen werden können.In FIG. 3 there is also a second one in addition to the first one Volume 15 shown. This second volume 15 and any other Tapes are copied according to the first tape 14. It So there are tapes with winding portions 23 ', as in the Measurement phase 23 are constructed. Until the completion of the complete second tape 15 is then wound as well Rest of the first tape after the measurement phase 23. Also when copying of the tape 15 and any other tapes can Pressure monitoring. There are additional, not shown change phases 31 in the second volume 15, which in the following tapes can be adopted.

Das Korrigieren des Vorschubs erfolgt zweckmäßigerweise in Schritten. Beispielsweise wird eine entstehende Druckzunahme in der sich anschließenden Trommelumdrehung in kleinsten Schritten je 10 Winkelgrad Trommelumdrehung abgebaut. Die Anzahl der Schritte ist abhängig von der Druckzunahme oder von der Druckabnahme. Kleine Druckänderungen bedingen weniger Schritte, größere Druckänderungen erfordern viele Schritte. Dabei kann die Anzahl der Schritte auch über eine Trommelumdrehung hinaus gehen. Bei schrittweiser Vorschubkorrektur ergibt sich ein besonders sauberer Aufbau des Bandes, da große Vorschubsprünge vermieden werden.The feedrate is expediently corrected in steps. For example, an emerging pressure increase in the following drum rotation in the smallest Steps reduced by 10 angular degrees of drum rotation. The number of steps depends on the increase in pressure or from the decrease in pressure. Small pressure changes are required fewer steps, larger pressure changes require many Steps. The number of steps can also be one Go out of drum rotation. With gradual feed correction the tape is particularly clean, because large jumps in feed are avoided.

Vorstehend wurde angenommen, daß in der Steuereinrichtung 24 kein Vorschub eingegeben ist, sondern daß der sich ab Wickelbeginn aufbauende Druck zu einer Überschreitung der Minustoleranz führt und eine entsprechende Vorschubänderung verursacht, bei der auch der Konuswinkel berücksichtigt wird. Das Verfahren kann aber auch so durchgeführt werden, daß die Steuereinrichtung 24 einen festen Vorschub aufweist, der bereits während der Meßphase 23 zur Wirkung kommt. Der feste Vorschub beruht beispielsweise auf Erfahrungswerten oder ist errechnet, indem er in Abhängigkeit von fadenspezifischen Daten bestimmt wird, wie Fadenfärbung, Drehung usw.Above it was assumed that in the control device 24 no feed has been entered, but that the off Start of winding build-up pressure to exceed the minus tolerance leads and a corresponding feed change caused, which also takes into account the cone angle. The method can also be carried out so that the Control device 24 has a fixed feed, which already comes into effect during the measurement phase 23. The firm For example, feed is based on empirical values or is calculated by depending on thread-specific data it is determined how thread coloring, rotation etc.

Anhand von Fig.7 wird ein Verfahren erläutert, bei dem das Kopieren des zweiten Bandes 15 und weiterer Bänder so durchgeführt wird, wie es zu Fig.6 erläutert wurde. Zugleich wird jedoch auch die Regeleinrichtung 27 ständig mit Druckmeßwerten des Drucksensors 18 beaufschlagt. Liefert der Drucksensor 18 Werte v1',v1'', welche außerhalb des -/+-Toleranzfeldes des vorgegebenen Druckwerts v2 bzw. des Mittelwerts v2' liegen, so wird ein Regelkreis 40 beaufschlagt, der Einfluß auf die Fadenzugkraft nimmt. Dies geschieht mit einem nicht näher dargestellten Verstellmotor 41, der Einfluß auf eine nicht näher dargestellte Verstelleinrichtung 42 zur Beeinflussung der Fadenzugkraft nimmt, beispielsweise auf eine Zentralverstellung der Gatterbremsen, welche die aufgewickelten Fäden weniger stark bremsen, wenn die Minustoleranzschwelle v1'' überschritten wird, und die die Fäden stärker bremsen, wenn die Plustoleranzschwelle v1' überschritten wird. Damit nimmt der Sensor 18 direkt Einfluß auf die Gatterfadenzugkraft.A method is explained with the aid of FIG copying the second tape 15 and other tapes like this is carried out, as was explained for Fig.6. at the same time However, the control device 27 is also constantly with measured pressure values of the pressure sensor 18 is applied. Delivers the Pressure sensor 18 values v1 ', v1' ', which are outside the - / + - tolerance field the predetermined pressure value v2 or the mean value v2 ', a control circuit 40 is applied, which Influences the thread tension. This happens with one Adjustment motor 41, not shown, the influence on an adjusting device 42, not shown, for influencing the thread tension increases, for example to one Central adjustment of the gate brakes, which the wound up Brake threads less strongly when the minus tolerance threshold v1 '' is exceeded, and the threads are stronger brake if the plus tolerance threshold v1 'is exceeded becomes. The sensor 18 thus has a direct influence on the creel tension.
