Abstract

The method for the laying of long wound material (20), such as wire, insulated or uninsulated leads, glass fibers, and suchlike, entails recording the position of the flanges (13,14) of the winding reel (11) by means of a sensing unit (37), and from the measured values of the sensing unit deriving control signals for the movement of the deflection roller. The speed of feed of the wound material is also recorded by a speed measurement unit and this value is also used for deriving the control signals for movement of the deflection roller. An independent claim is included for a device for implementing the method in which the laying unit (32) has a sensing unit which records at least the position of the reel flanges and also the coil diameter of the already laid material.

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Verlegen von langgestrecktem Wickelgut wie beispielsweise Draht, isolierten oder nicht-isolierten Litzen, Glasfasern und dergleichen sowie eine Vorrichtung zur Durchführung des Verfahrens.The present invention relates to a method for laying elongated winding material such as wire, insulated or non-insulated strands, glass fibers and the like, and an apparatus for performing the method.

Bei bekannten Wickelverfahren wird ein strangförmiges Gut beispielsweise auf eine sich drehende Spule aufgebracht und damit auf den Kern der Spule aufgewickelt. Um eine lagenweise Wicklung zu erreichen, d.h. die Drahtwindungen nebeneinander auf die Spule zu legen, bewegt sich eine Umlenkrolle, die das Wickelgut zur Spule führt, im wesentlichen parallel zur Achsrichtung der sich drehenden Spule. Es ist auch bekannt, die Spule feststehend anzuordnen und um die Spule einen sich zusätzlich axial bewegenden Flyer laufen zu lassen, der das Wickelgut lagenweise um die Spule legt.In known winding method, a strand-like material is applied, for example, to a rotating coil and thus wound on the core of the coil. To achieve a layered winding, i. To place the wire windings next to each other on the spool, a deflection roller, which leads the winding material to the spool, moves substantially parallel to the axial direction of the rotating spool. It is also known to arrange the coil stationary and to let the coil run an additionally axially moving flyer, which places the winding material in layers around the coil.

Um eine besondere Wicklungsart (Lage an Lage) zu erhalten, ist es auch bekannt, die axial verschiebliche Verlegeeinheit, auf welcher die Umlenkrolle angeordnet ist, der normalen Steigungsrichtung um einen gewissen Betrag nachlaufen zu lassen. Dadurch entsteht zwischen dem auflaufenden Wickelgut und der bereits liegenden Wicklung ein seitlicher Druck, der das Wickelgut bis zu letzten Windung der betreffenden Lage in gewünschter Weise verlegt.In order to obtain a special type of winding (position on layer), it is also known that the axially displaceable laying unit, on which the deflection roller is arranged to run after the normal pitch direction by a certain amount. This creates a lateral pressure between the winding up winding material and the already lying winding, which moves the winding material up to the last turn of the respective layer in the desired manner.

Erfolgt keine rechtzeitige Umkehr der Bewegungsrichtung der Verlegeeinheit, so erreicht das Wickelgut den Spulenflansch. Es steigt auf die letzte Windung der vollständig gewickelten Lage und bildet, bei weiter ausbleibender Richtungsumkehr direkt am Flansch einen so genannten "Berg" der Wicklung aus.If there is no timely reversal of the direction of movement of the laying unit, the winding material reaches the reel flange. It rises to the last turn of the fully wound layer and forms, with no further reversal of direction directly on the flange of a so-called "mountain" of the winding.

Dabei ergibt sich bei zu spät erfolgender Richtungsumkehr der Verlegeeinheit ein axialer Druck auf den Spulenflansch, der sich hierdurch - insbesondere bei Kunststoffspulen - elastisch verformt. Dies wirkt sich einerseits nachteilig auf die Haltbarkeit der Kunststoffspulen aus, andererseits ergeben sich durch die elastischen Rückstellkräfte des Flansches Probleme beim späteren Abwickeln des langgestreckten Wickelguts von der Spule.This results in too late reversal of direction of the laying unit, an axial pressure on the spool flange, thereby elastically deformed - especially in plastic coils. On the one hand, this has a disadvantageous effect on the durability of the plastic bobbins, on the other hand problems arise during the subsequent unwinding of the elongated winding material from the bobbin due to the elastic restoring forces of the flange.

Direkt nach der Richtungsumkehr der Verlegeeinheit im Wickelprozess fehlt der Gegenflankendruck einer vorausgegangenen Wicklung. Daher hat das Wickelgut an dieser Stelle die Neigung, sich abhängig von der Größe des Einlaufswinkels in anfangs größeren Abständen, also mit größerer Steigung, aufzuwickeln. Dadurch entstehen zu Beginn in jeder Wicklungslage Zwischenräume, sogenannte "Täler", in die sich die Windungen der darüber liegenden Lage einwickeln, was zu Schwierigkeiten beim späteren Abwickeln des Wickelguts führen kann.Immediately after the reversal of direction of the laying unit in the winding process, the back pressure of a previous winding is missing. Therefore, the winding material at this point has the tendency to wind depending on the size of the inlet angle initially larger distances, ie with a larger pitch. This creates at the beginning in each winding layer gaps, so-called "valleys", in which wrap the turns of the overlying layer, which can lead to difficulties in the subsequent unwinding of the winding material.

Erfolgt die Richtungsumkehr der Verlegeeinheit jedoch zu spät, so überlappen sich, wie oben bereits erwähnt, mehrere Windungen am betreffenden Spulenflansch. Solche Häufungen von Wickellagen werden als Berge bezeichnet. In der Folge dieser Erscheinungsformen bilden sich, vermehrt in den Randbereichen der Wicklung, ungleichmäßige Lagen aus.However, if the direction reversal of the laying unit too late, so overlap, as already mentioned above, several turns on the relevant coil flange. Such accumulations of winding layers are referred to as mountains. As a result of these manifestations, uneven layers are formed, increasingly in the peripheral areas of the winding.

Ebenso wird die Ausbildung von "Bergen" und "Tälern" durch eine unsachgemäße Einstellung der Verlegebreite des Wickelguts oder - wie erwähnt - infolge einer Verformung der Spulenflansche verursacht.Similarly, the formation of "mountains" and "valleys" by an improper adjustment of the laying width of the winding material or - as mentioned - caused by a deformation of the reel flanges.

Zusätzlich zu den durch die Ausbildung von Bergen und Tälern bedingten ungleichmäßigen und dadurch ungenügenden Nutzung des Wickelraums wird das jeweilige Wickelgut übermäßig beansprucht und kann somit beschädigt werden.In addition to the uneven and thus insufficient use of the winding space due to the formation of mountains and valleys, the respective winding material is excessively stressed and can thus be damaged.

Zur möglichst optimalen Nutzung des Wickelraums sowie zur Vermeidung einer elastischen Verformung von Spulenflanschen ist es daher anzustreben, bei der lagenweisen Verlegung des Wickelguts die Entstehung von Bergen und Tälern zu vermeiden.For the best possible use of the winding space and to avoid elastic deformation of spool flanges, it is therefore desirable to avoid the formation of mountains and valleys in the layered laying of the winding material.

Zum Zweck der Geschwindigkeitssynchronisation sind Steuereinrichtungen, so genannte "Tänzer" bekannt, die entweder die Laufgeschwindigkeit der Spule oder die Laufgeschwindigkeit des die Spule umkreisenden Flyers beeinflussen. Zur Erfassung von "Bergen" und "Tälern" wird beispielsweise die Geschwindigkeit des Wickelguts über das Tänzersignal oder mittels eines Analogtachos ermittelt. Diese Verfahren liefern relativ ungenaue Signale, aufgrund derer keine Aussage über die Amplituden der Berge und Täler gemacht werden kann.For the purpose of speed synchronization, control devices, so-called "dancers" are known which influence either the running speed of the spool or the running speed of the flyer orbiting the spool. To record "mountains" and "valleys", for example, the speed of the winding material is determined via the dancer signal or by means of an analogue tacho. These methods provide relatively inaccurate signals, due to which no statement about the amplitudes of the mountains and valleys can be made.

Aus der DE 196 45 992 A1 ist eine Steuervorrichtung bekannt, die einen Drehzahlsensor zum Ermitteln der Drehzahl eines Flyers oder eines Wicklers aufweist, weiterhin eine Steuereinheit zum Aufnehmen von Signalen des Drehzahlsensors und eine Verlegeeinheit zum Aufbringen des langgestreckten Wickelguts auf die Spule. Zum Ansteuern der Verlegeeinheit kann die Steuereinheit entsprechend eines ermittelten Verlegegeschwindigkeits-Sollwerts die Verlegeeinheit ansteuern und eine Verlegebreitenverstellung durchführen. Auch eine automatische Verlegebreiteneinstellung kann realisiert werden. Dabei werden z. B. die Toleranzen der Spule berücksichtigt oder auch die Veränderung der Spulenmaße, die durch eine elastische Verformung der Flansche beim Wickeln entstehen kann. Zusätzlich kann die Steuereinheit eine automatische Umschaltpunktkorrektur durchführen. Die Verlegebreitenabweichung wird dabei im Bereich langsamer Drehzahlen über eine Änderung der Drehzahl im Verhältnis zu einer Referenzdrehzahl ermittelt, die mitten auf der Spule gemessen wird. Bei höheren Drehzahlen wird ein Tänzersignal herangezogen, welches den Wickler steuert.From the DE 196 45 992 A1 a control device is known, which has a rotational speed sensor for determining the rotational speed of a flyer or a winder, furthermore a control unit for receiving signals of the rotational speed sensor and a laying unit for applying the elongate winding material to the spool. For controlling the laying unit, the control unit can control the laying unit in accordance with a determined laying speed setpoint and carry out a laying width adjustment. An automatic laying width adjustment can also be realized. This z. B. takes into account the tolerances of the coil or the change in the coil dimensions, which can be caused by elastic deformation of the flanges during winding. In addition, the control unit can perform an automatic switching point correction. The laying width deviation is determined in the range of slow speeds by changing the speed in relation to a reference speed, which is measured in the middle of the coil. at higher speeds, a dancer signal is used, which controls the winder.

Andere bekannte gewordene Systeme verwenden zur digitalen Erfassung von Bergen und Tälern die Drahteinlauflänge, bezogen auf eine bestimmte Anzahl von Spulenumdrehungen, als Parameter. Dabei wird ein Mittelwertsdurchmesser auf der Spule ermittelt und dieser mit den Durchmessern an den Umschaltpunkten verglichen.Other known systems use the wire inlet length, with respect to a certain number of coil revolutions, as a parameter for the digital detection of mountains and valleys. An average diameter on the coil is determined and compared with the diameters at the switching points.

Nachteilig an diesen beiden Systemen ist die indirekte Erfassung der Wicklungsqualität anhand von Parametern wie der Drehzahl, der Drahteinlauflänge oder der Verlegegeschwindigkeit. Eine Verlegebreitenverstellung kann erst vorgenommen werden, wenn Abweichungen dieser Parameter auftreten oder die Spulenflansche schon verformt sind, es also bereits zu einem "deutlich" ungleichmäßigen Wicklungsbild gekommen ist.A disadvantage of these two systems is the indirect detection of the winding quality based on parameters such as the rotational speed, the wire inlet length or the laying speed. A laying width adjustment can be made only if deviations of these parameters occur or the coil flanges are already deformed, so it has already come to a "clearly" uneven winding pattern.

In der DE 200 084 05 U1 wird vorgeschlagen, dass ein Laserabstandssensor mit seinem Laserstrahl so angebracht wird, dass er mit dem aufzuspulenden Draht eine fluchtende Linie bildet. Dieser Laserabstandssensor erfasst den Abstand zu einem auf einen Spulenkörper gewickelten Wickelgut und gibt den Wert an eine SPS-Steuerung aus. Diese vergleicht den Wert mit hinterlegten Daten, errechnet und wertet Änderungen aus und sendet damit Steuersignale an eine Verlegeeinheit, die hierdurch ihre Geschwindigkeit ändert, so dass eine gleichmäßige Wicklung auf der Spule entsteht. Dabei erkennt der Laserabstandssensor auch den Flansch des Spulenkörpers. Diese große Abstandsänderung wird in der Steuerung als Wendesignal ausgewertet und führt zur einer automatischen Reversion der Bewegungsrichtung der Verlegeeinheit.In the DE 200 084 05 U1 It is proposed that a laser distance sensor with its laser beam is mounted so that it forms an aligned line with the wire aufzuspulenden. This laser distance sensor detects the distance to a wound on a bobbin winding material and outputs the value to a PLC controller. This compares the value with stored data, calculates and evaluates changes and thus sends control signals to a laying unit, which thereby changes their speed, so that a uniform winding is formed on the coil. In this case, the laser distance sensor also detects the flange of the bobbin. This large change in distance is evaluated in the controller as a turn signal and leads to an automatic reversion of the direction of movement of the laying unit.

Nachteilig an diesem System ist, dass mit dem Laserabstandssensor nur der Abstand der Umlenkrolle zum Wickelgut erfasst wird. Der Durchmesser der Wicklung wird nicht ermittelt und bleibt unberücksichtigt. Damit kann zwar ein Signal zur Beschleunigung oder Verlangsamung der Verschiebeeinheit abgeleitet werden, eine exakte Berechnung der zum Ausgleich der ungleichmäßigen Oberfläche erforderlichen Geschwindigkeit der Verlegeeinrichtung ist in der beschriebenen Weise jedoch nicht möglich.A disadvantage of this system is that with the laser distance sensor only the distance of the deflection roller is detected to the winding material. The diameter of the winding is not determined and is ignored. This can indeed a Signal for accelerating or decelerating the displacement unit are derived, however, an exact calculation of the required speed to compensate for the uneven surface speed of the laying device is not possible in the manner described.

Der Spulenflansch wird aufgrund der mit dem aufzuspulenden Wickelgut fluchtenden Anordnung des Laserabstandssensors erst dann erkannt, wenn sich die Verlegeeinheit mit dem Wickelgut auf Höhe des Spulenflansches befindet. Der optimale Zeitpunkt zum Umschalten der Verfahrrichtung der Verlegeeinheit ist dann bereits vorbei. In der Folge entsteht eine elastische Verformung des Spulenflansches und die Ausbildung eines sich am Flansch anlehnenden Berges.Due to the arrangement of the laser distance sensor aligned with the winding material to be wound up, the reel flange is only recognized when the laying unit with the winding material is at the level of the reel flange. The optimum time for switching the travel direction of the laying unit is then already over. As a result, an elastic deformation of the coil flange and the formation of a leaning on the flange mountain arises.

Der Einsatz der bekannten Verfahren zur Verbesserung des Wickelbildes bei der Verlegung von Wickelgut ist zudem erschwert, wenn die Energieversorgung und der Signalaustausch wie beispielsweise bei Verlitzmaschinen nur über rotierende Bauelemente möglich ist.The use of the known method for improving the winding pattern in the laying of winding material is also difficult if the power supply and the signal exchange, such as in Verlitzmaschinen only via rotating components is possible.

Die vorliegende Erfindung stellt sich die Aufgabe, ein Verfahren zum Verlegen von langgestrecktem Wickelgut zur Verfügung zu stellen, welches ein möglichst gutes Wickelbild ohne Berge und Täler auf beliebigen Spulen erzeugt. Zudem soll das Verfahren möglichst bedienerfreundlich gestaltet sein und auf allen Spulsystemen eingesetzt werden können. Ferner soll eine Vorrichtung zur Durchführung dieses Verfahrens angegeben werden, welche die Energieversorgung und den Signalaustausch über rotierende Bauelemente ermöglicht.The present invention has as its object to provide a method for laying elongate winding material available, which produces the best possible winding image without mountains and valleys on any coil. In addition, the method should be designed as user-friendly as possible and can be used on all winding systems. Furthermore, an apparatus for carrying out this method is to be specified, which enables the power supply and the signal exchange via rotating components.

Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des Anspruchs 1 gelöst. Die erfindungsgemäße Vorrichtung zur Durchführung des Verfahrens ist Gegenstand des Anspruchs 7. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.This object is achieved by the subject matter of claim 1. The device according to the invention for carrying out the method is the subject of claim 7. Advantageous developments are the subject of the dependent claims.

Mit dem erfindungsgemäßen Verfahren wird eine Möglichkeit zur Erzielung eines möglichst guten Wickelbildes ohne Berge und Täler auf beliebigen Spulen zur Verfügung gestellt, die gleichzeitig eine elastische Verformung der Spulenflansche vermeidet und gegenüber den im Stand der Technik bekannten Verfahren erhebliche Vorteile aufweist.With the method according to the invention, a possibility for achieving the best possible winding image without mountains and valleys on any coil is provided, which simultaneously avoids an elastic deformation of the reel flanges and has considerable advantages over the methods known in the prior art.

Besonders vorteilhaft ist es, wenn sich die Wickelspule während des Wickelvorgangs dreht. In diesem Fall wird dann eine sich hin- und her bewegende Verlegeeinheit verwendet, die das strangförmige Gut in der jeweils gewünschten Position zur Spule führt und sich im wesentlichen parallel zur Achse der Spule bewegt. Dabei kann die Spule sowohl horizontal als auch vertikal angeordnet sein.It is particularly advantageous if the reel spool rotates during the winding process. In this case, then a reciprocating laying unit is used, which leads the strand-like material in the respectively desired position to the coil and moves substantially parallel to the axis of the coil. In this case, the coil can be arranged both horizontally and vertically.

In einer anderen vorteilhaften Weiterbildung des erfindungsgemäßen Verfahrens steht die Wickelspule während des Wickelvorgangs still. In diesem Fall bewegt sich die Verlegeeinrichtung mit einem sogenannten Flyer auf einer im wesentlichen zylindrischen Fläche um die Spule herum und legt dabei das Wickelgut auf die Wickelspule.In another advantageous embodiment of the method according to the invention, the reel spool stands still during the winding process. In this case, the laying device moves with a so-called flyer on a substantially cylindrical surface around the coil and thereby places the winding material on the reel spool.

Das Wickelgut wird über eine Umlenkrolle zur Spule geführt, welche auf der Verlegeeinheit angeordnet ist. Das erfindungsgemäße Verfahren verwendet bevorzugt eine Sensoreinrichtung mit mindestens einem Laserabstandssensor, der nach dem Triangulationsverfahren arbeitet und ebenfalls auf der Verlegeeinheit angeordnet ist.The winding material is guided over a deflection roller to the coil, which is arranged on the laying unit. The method according to the invention preferably uses a sensor device with at least one laser distance sensor which operates according to the triangulation method and is likewise arranged on the laying unit.

Zur Messung des Abstands des Wickelguts bzw. des Spulenkörpers von der Verlegeeinheit ist es möglich Sensoren zu verwenden, welche die Laufzeit von Schallwellen, Lichtwellen beispielsweise im sichtbaren oder Infrarotbereich oder generell elektromagnetischem Wellen, insbesondere im Mikrowellenbereich, erfassen und bevorzugt nach dem Triangulationsverfahren auswerten. Dabei kann, bei einer Aussendung von Pulsen beispielsweise auch das Pulslaufzeitverfahren zur Ermittlung des Abstandswerts verwendet werden. Ferner können dabei auch Sensoren mit einer Laser- oder LED-Lichtquelle eingesetzt werden, die zur Messwertbestimmung vorzugsweise das Triangulationsverfahren verwenden.For measuring the distance of the winding material or the bobbin from the laying unit, it is possible to use sensors which detect the propagation time of sound waves, light waves, for example in the visible or infrared range or generally electromagnetic waves, especially in the microwave range, and preferably evaluate according to the triangulation method. In this case, when pulses are transmitted, for example, the pulse transit time method can also be used to determine the distance value. You can also do this It is also possible to use sensors with a laser or LED light source which preferably use the triangulation method to determine the measured value.

Die Sensoreinheit vermisst beim erfindungsgemäßen Verfahren während der Fahrt der Verlegeeinheit die Spule sowie die Position der Spulenflansche und ermittelt so Spulenwinkel, Wickelgutwinkel, sowie Berge und Täler der Wicklung. Zur Steuerung des Verfahrens werden vorzugsweise keine festen Spulengeometrien vorgegeben, so dass dieses Verfahren auf allen bekannten Spulenformen, wie beispielsweise zylindrischen, konischen und bi-konischen Spulen eingesetzt werden kann.The sensor unit measures in the process of the invention while driving the laying unit, the coil and the position of the coil flanges and thus determines coil angle, winding material, as well as mountains and valleys of the winding. For controlling the method preferably no fixed coil geometries are given, so that this method can be used on all known coil shapes, such as cylindrical, conical and bi-conical coils.

Vorzugsweise wird zusätzlich mittels einer Geschwindigkeitsmesseinrichtung die Zufuhrgeschwindigkeit des Wickelguts erfasst und anhand der ermittelten Werte der Sollwert für die Positionssteuerung der Verlegeeinheit sowie für die Antriebsgeschwindigkeit der Wickelspule bzw. des Flyers abgeleitet.Preferably, the feed rate of the winding material is additionally detected by means of a speed measuring device, and based on the determined values, the desired value for the position control of the laying unit and for the drive speed of the reel spool or the flyer are derived.

Beim erfindungsgemäßen Verfahren wird die Sensoreinheit auch zur Erkennung der Spulenflansche verwendet. Dabei wird bevorzugt bei jedem Verlegehub anhand der Messwertänderungen der Sensoreinheit die Position des Flansches ermittelt und die Werte für die darauf folgende Steuerung der Richtungsumkehr verwendet. Vorzugsweise sorgt das erfindungsgemäße Verfahren automatisch für die notwendige Nachführung der Umschaltpunkte. Durch diese permanente Korrektur der Umschaltpunkte wird eine unerwünschte Berg- bzw. Talbildung des Wickelgutes am Flansch verhindert. Zudem ergibt sich eine sehr hohe Bedienerfreundlichkeit, da keine Korrektur der Umschaltpunkte durch das Bedienpersonal erforderlich ist. Zudem ist diese Funktion unabhängig vom verwendeten Verlegemuster der Wicklung.In the method according to the invention, the sensor unit is also used to detect the reel flanges. In this case, the position of the flange is preferably determined on each laying stroke on the basis of the measured value changes of the sensor unit, and the values for the subsequent control of the direction reversal are used. Preferably, the method according to the invention automatically ensures the necessary tracking of the switching points. This permanent correction of the switching points an undesirable mountain or valley formation of the winding material is prevented at the flange. In addition, there is a very high level of user-friendliness, since no correction of the switching points by the operating personnel is required. In addition, this function is independent of the used laying pattern of the winding.

Wird die Spule beispielsweise nach dem in der Patentschrift EP 0 334 211 B1 bekannt gewordenen Wickelverfahren bewickelt, so ist eine im erfindungsgemäßen Verfahren vorgesehene Erfassung des Spulen- bzw. Wickelgutwinkels erforderlich. Bei der Verlegung nach dem in dieser Patentschrift beschriebenen Muster wird der Spulenkern gezielt schief bewickelt. Der Wickelgutwinkel kann beim erfindungsgemäßen Verfahren anhand der Sensoreinheit vermessen, überwacht und mittels einer geeigneten Verlegesteuerung nachgeregelt werden. Hierzu sieht das Verfahren vor, den Spulendurchmesser an beiden Spulenseiten kurz vor dem Flansch zu speichern. Über die Differenz der Spulendurchmesser (d1 und d2) und der Distanz der Messpunkte (Länge I) kann der Winkel des Wickelgutes wie folgt berechnet werden: a = arctan l d 1 - d 2

Figure imgb0001
If the coil, for example, after that in the patent EP 0 334 211 B1 wound wrapping process wound, so provided in the inventive method detection of the coil or winding material is required. When laying according to the pattern described in this patent, the bobbin is deliberately wound obliquely. The winding material angle can be measured in the inventive method using the sensor unit, monitored and readjusted by means of a suitable laying control. For this purpose, the method provides to store the coil diameter at both coil sides just before the flange. The difference between the coil diameters (d 1 and d 2 ) and the distance of the measuring points (length I) allows the angle of the winding material to be calculated as follows: a = arctan l d 1 - d 2
Figure imgb0001

Durch die Ermittlung des Spulen- bzw. Wickelgutwinkels und die automatische Flanscherkennung ist es möglich, dieses Verfahren unabhängig vom Spulenaufbau einzusetzen. Die ermittelten Winkel werden in die Steuerung der automatischen Verlegung, bzw. in die Flanscherkennung mit einbezogen. Daher kann beispielsweise eine in der EP 0 334 211 B1 beschriebene schiefe Wicklung sowie die Verlegung auf zylindrischen, konischen und bi-konischen Spulen gesteuert werden. Dabei kann, nach dem Erfassen von Tälern, die Wickelgeschwindigkeit über eine Verminderung der Drehgeschwindigkeit der Spule bzw. des Flyers gesenkt und/oder die axiale Geschwindigkeit der Verlegeeinheit gedrosselt werden. Bei einer Erfassung von sogenannten Bergen kann, um ein gleichmäßiges Wickelbild wieder herzustellen, die Wickelgeschwindigkeit erhöht und/oder sogenannte Schiebeschritte der Verlegeeinheit in Richtung der Spulenachse durchgeführt werden.By determining the coil or winding material angle and the automatic flange detection, it is possible to use this method regardless of the coil structure. The determined angles are included in the control of the automatic installation or in the flange detection. Therefore, for example, in the EP 0 334 211 B1 described oblique winding and the installation on cylindrical, conical and bi-conical coils are controlled. In this case, after the detection of valleys, the winding speed can be lowered via a reduction in the rotational speed of the coil or of the flyer and / or the axial speed of the laying unit can be throttled. In the case of detection of so-called mountains, in order to restore a uniform winding pattern, the winding speed can be increased and / or so-called sliding steps of the laying unit in the direction of the coil axis can be carried out.

Fig. 1 zeigt einen schematischen Querschnitt durch eine Wickelvorrichtung 1 zur Durchführung des erfindungsgemäßen Verfahrens. In der Figur ist links die rechte Hälfte einer Wickelspule 11, bestehend aus dem Spulenkern 12 und den beiden Flanschen 13 und 14 im Schnitt gezeigt. Aufgabe des erfindungsgemäßen Verfahrens ist es, den Spulenkern 12 möglichst gleichmäßig zur optimalen Nutzung des Wickelvolumens der Wickelspule 11 mit langgestrecktem Wickelgut 20 zu bewickeln. Dabei sind in der Figur die beispielhaft dargestellten unterwünschten Täler mit 22 und die Berge mit 21 bezeichnet.Fig. 1 shows a schematic cross section through a winding device 1 for carrying out the method according to the invention. In the figure, the right half of a winding spool 11, consisting of the spool core 12 and the two flanges 13 and 14 is shown in section on the left. The object of the method according to the invention is to wind the spool core 12 as evenly as possible for optimal utilization of the winding volume of the reel spool 11 with elongate winding material 20. In the figure, the unwanted valleys exemplified are designated 22 and the mountains 21.

Rechts in der Fig. 1 ist die Verlegeeinrichtung 31 dargestellt. Die Verlegeeinheit 32 ist auf einer Spindelachse 39 gelagert. Eine Drehbewegung der Spindelachse 39 im oder gegen den Uhrzeigersinn bewirkt eine Bewegung der Verlegeeinheit 32 in einer mit dem Doppelpfeil 30 angedeuteten Richtungen im wesentlichen parallel zur Spulenachse. Angetrieben wird die Spindelachse 39 durch den Motor 38. Die Verlegeeinheit 32 weist einen Träger 33 auf, auf dem die Umlenkrolle 34 sowie die Sensoreinheit 37 angeordnet sind.Right in Fig. 1, the laying device 31 is shown. The laying unit 32 is mounted on a spindle axis 39. A rotational movement of the spindle axis 39 in the clockwise or counterclockwise direction causes a movement of the laying unit 32 in a direction indicated by the double arrow 30 directions substantially parallel to the coil axis. The spindle axis 39 is driven by the motor 38. The laying unit 32 has a carrier 33 on which the deflection roller 34 and the sensor unit 37 are arranged.

Bei der Verlegung des Wickelguts auf der Spule wird dieses über die Umlenkrolle 34 zur Wickelspule 11 geführt. Dabei wird zur gleichmäßigen Verteilung des Wickelguts auf der Spule die Verlegeeinheit 32 mittels des Motors 38 und der Spindelachse 39 bewegt.When laying the winding material on the spool this is guided over the deflection roller 34 to the winding spool 11. In this case, the laying unit 32 is moved by means of the motor 38 and the spindle axis 39 for uniform distribution of the winding material on the spool.

Die bereits verlegte Wicklung und die Spule werden während des Verfahrens von der Sensoreinheit 37 vermessen. Die Sensoreinheit ist in der Lage, die Spulenflansche 13 und 14 sowie den Wicklungsdurchmesser der zuletzt verlegten Lage zu erfassen. Die optischen Sensoren der Sensoreinheit 37 arbeiten in einer bevorzugten Ausführungsform nach dem Triangulationsverfahren und benötigen somit keinen Reflektor.The already laid winding and the coil are measured by the sensor unit 37 during the process. The sensor unit is capable of detecting the reel flanges 13 and 14 as well as the winding diameter of the last laid layer. The optical sensors of the sensor unit 37 operate in a preferred embodiment according to the triangulation method and thus require no reflector.

Die Sensoreinheit 37 dient auch zur Erkennung der Position der Spulenflansche. Bei jedem Verlegehub wird anhand der Messwertänderungen der Sensoreinheit die Position des Flansches ermittelt und für die darauffolgende Richtungsumkehr verwendet. Alternativ zur Benutzung zweier Sensoren, die zu beiden Seiten der Umlenkrolle angeordnet sind, kann das Verfahren auch mit einer Sensoreinheit, bestehend aus nur einem Sensor, arbeiten. Die Sensoreinheit muss in diesem Fall derart ausgeführt sein, dass dieser eine Sensor während des Betriebes zu den Umschaltpunkten hin verfahrbar bzw. schwenkbar ausgeführt ist.The sensor unit 37 also serves to detect the position of the spool flanges. With each laying stroke, the position of the flange is determined on the basis of the measured value changes of the sensor unit and used for the subsequent reversal of the direction. Alternatively to the use of two sensors, which are arranged on both sides of the deflection roller, the method can also work with a sensor unit consisting of only one sensor. In this case, the sensor unit must be designed in such a way that, during operation, it is designed to be movable or pivotable relative to the switching points.

In dieser Ausführungsform der Vorrichtung weist die Steuereinrichtung 51 eine Mikroprozessorrecheneinheit 55 sowie einen dieser zugeordneten Speicher 53 auf. Die Energieversorgung und der Signalaustausch zwischen den Elementen der Steuereinrichtung 51 gestaltet sich bei der beispielhaft dargestellten Verlitzmaschine besonders schwierig, da die Energieversorgung und der Signalaustausch nur über eine rotierende Welle möglich sind. Die Verbindungsleitung zum Motor 38 der Verlegeeinrichtung 31, ist in Fig. 2 beispielhaft durch die Leitung 52 gezeigt. Auf die Darstellung der weiteren Elemente der Steuereinrichtung 51, die in Fig. 3 schematisch gezeigt ist, wird in Fig. 2 aus Gründen der Übersichtlichkeit verzichtet.Fig. 2 shows the device 1 for carrying out the method according to the invention, in which the data-processing elements of the control device 51 is largely installed in the bobbin. In this embodiment of the device, the control device 51 has a microprocessor computing unit 55 and a memory 53 associated therewith. The power supply and the signal exchange between the elements of the control device 51 is particularly difficult in the case of the Verlitzmaschine shown as an example, since the power supply and the signal exchange are possible only via a rotating shaft. The connecting line to the motor 38 of the laying device 31 is shown by way of example in FIG. 2 through the line 52. On the representation of the other elements of the control device 51, which is shown schematically in Fig. 3, is omitted in Fig. 2 for reasons of clarity.

Fig. 3 zeigt ein schematisches Blockschaltbild der Steuereinrichtung 51 für das erfindungsgemäße Verfahren. Die Eingangswerte der Mikroprozessoreinheit 55 werden im wesentlichen von der Sensoreinheit 37 und der Geschwindigkeitsmesseinrichtung 57 für die Zuführung des Wickelgutes erfasst. Die Mikroprozessorrecheneinheit 55 ist mit einem Speicher 53 verbunden, der in beliebig viele, auch unterschiedliche Speicherbereiche aufgeteilt sein kann. In diesem Speicher 23 ist ein Programm gespeichert, welches die Mikroprozessorrecheneinheit 55 steuert. Aus den Eingangsdaten der Sensoreinheit 37 und der Geschwindigkeitsmesseinrichtung 57 für die Zuführung des Wickelguts leitet die Mikroprozessorrecheneinheit 55 die Steuersignale für den Motor 38 der Spindelachse 39 sowie für den Wickelantrieb 56 ab, der bei der beispielhaft beschriebenen Verlitzmaschine die Wickelspule 11 antreibt.3 shows a schematic block diagram of the control device 51 for the method according to the invention. The input values of the microprocessor unit 55 are essentially detected by the sensor unit 37 and the speed measuring device 57 for the supply of the winding material. The micro-processor unit 55 is connected to a memory 53 which may be divided into any number of memory areas, including different ones. In this memory 23, a program is stored which controls the micro-processor unit 55. From the input data of the sensor unit 37 and the speed measuring device 57 for the supply of the winding material, the microprocessor computing unit 55 derives the control signals for the motor 38 of the spindle axis 39 and for the winding drive 56, which drives the winding reel 11 in the case of the Verlitzmaschine described by way of example.

Die im erfindungsgemäßen Verfahren verwendete Steuereinrichtung 51 beinhaltet eine diskrete Schnittstelle zu gängigen Antriebssystemen. Im Falle der Verlitzmaschine, für die das erfindungsgemäße Verfahren beispielhaft dargestellt ist, ist dies eine Schrittmotorlösung, die mit analogen und digitalen Signalen angesteuert wird. Zusätzlich erfolgt hierüber eine Positions-Ist-Wert-Erfassung für das Positioniermodul. Als weitere Schnittstelle zum Antrieb weist die Steuereinrichtung 51 eine CAN-Bus Schnittstelle auf. Die Kommunikation erfolgt in der bevorzugten Ausführungsform über die Schnittstelle RS485. Eine Profi-Bus Ansteuerung zur Kommunikation mit gängigen Steuerungstypen ist vorgesehen.The control device 51 used in the method according to the invention includes a discrete interface to conventional drive systems. In the case of the Verlitzmaschine for which the inventive method is shown by way of example, this is a stepper motor solution, which is driven with analog and digital signals. In addition, this is done via a position-actual value detection for the positioning module. As a further interface to the drive, the control device 51 has a CAN bus interface. Communication in the preferred embodiment is via the RS485 interface. A professional bus control for communication with common control types is provided.
