Description

Die Erfindung betrifft ein Verfahren zum Aufwickeln einer Materialbahn auf einen Wickelkern einer Wikkelstation, bei dem die Materialbahn mit einem Umschlingungswinkel kleiner als 180° um eine Anpreßwalze geführt wird, die gegen einen drehenden Wickel der Materialbahn anliegt, sowie eine Vorrichtung zum Aufwikkein einer Materialbahn.The invention relates to a method for winding a material web onto a winding core of a winding station, in which the material web is guided with a wrap angle of less than 180 ° around a pressure roller, which bears against a rotating winding of the material web, and a device for winding up a material web.

Bei der Produktion von bahnförmigen Materialien aus Papier, Kunststoff und dergleichen wird das Endprodukt im allgemeinen auf einen Wickelkern aufgewickelt. Hierzu werden Zweifach- und Dreifach-Wendewickler eingesetzt, bei denen die Wickelvorrichtung, wie der Name besagt, aus zwei oder drie Wickelstationen besteht. Zweifach- und Dreifach-Wendewickler erlauben, die Produktion beim Abschlagen der Materialbahn ohne Unterbrechung fortzusetzen. Sobald der maximale Wickeldurchmesser beim Aufwickeln der Materialbahn erreicht ist, schwenkt derwendewickler einen leeren Wickelkern in eine Position, die ein Abschlagen bzw. ein Abtrennen der laufenden Materialbahn ermöglicht. Dies geschieht in einer Weise, bei der die Materialbahn von dem leeren Wickelkern mitgenommen wird.In the production of sheet materials made of paper, plastic and the like, the end product is generally wound on a winding core. For this purpose, double and triple turret winders are used, in which the winding device, as the name suggests, consists of two or three winding stations. Double and triple turret rewinder allow production to continue without interruption when the web is cut off. As soon as the maximum winding diameter is reached when winding the material web, the reversing winder swivels an empty winding core into a position which enables the running material web to be cut off or cut off. This is done in such a way that the material web is carried along by the empty winding core.

Aus der DE-OS 3 040 398 ist eine Vorrichtung zum Auswechseln von fertigen Wickeln gegen leere Wikkelkerne in einer Dopeltragwalzenwickelmaschine zum Aufwickeln von Bahnen, insbesondere Papierbahnen, bekannt. Der fertige Wickel wird mittels einer Ausdrückvorrichtung von der Wickelstation zu einer eine seitlich angeordnete Ausziehvorrichtung aufweisenden Ausziehstation zum Ausziehen der Wickelachse geholt. An beiden Bahnseiten ist je ein Hebel gelagert, dessen freies Ende einen Greifer zum Erfassen des leeren Wickelkerns aufweist. Die Hebel sind derart zwischen der Ausziehstation und der Wickelstation gelagert, daß sich die Greifer in einer Endstellung in der Ausziehstation zur Aufnahme eines leeren Wickelkerns und in der anderen Endstellung in der Wickelstation zur Abgabe des Wickelkerns befinden.DE-OS 3 040 398 discloses a device for exchanging finished windings for empty winding cores in a double carrier roll winding machine for winding webs, in particular paper webs. The finished roll is brought from the winding station to a pull-out station having a pull-out device arranged on the side for pulling out the winding shaft by means of a push-out device. A lever is mounted on both sides of the web, the free end of which has a gripper for gripping the empty winding core. The levers are mounted between the pull-out station and the winding station in such a way that the grippers are in one end position in the pull-out station for receiving an empty winding core and in the other end position in the winding station for dispensing the winding core.

Die DE-OS 3 216 110 beschreibt eine Wickelmaschine mit einer zwischen kraftbetätigten Wickelhebeln gelagerten Aufwickelachse, einer mit der Aufwickelsachse zusammenwirkenden Andruckwalze und einer Tragwalze für den Wickel. Est werden bei dieser Wickelmaschine die Schwenkbewegungen der Wickelhebel und von Schwenkhebeln für jeden Wickeldurchmesser der Tragwalze einander überlagert. Die Schwenkhebel stützen den Wickel im wesentlichen von unten ab. Durch die Fortsetzung der Schwenkbewegungen sowohl der Wickel hebel als auch der Tragwalze über den Wickelbereich hinaus entfernen sich die Tragwalze und der Wickel soweit voneinander, daß der Wickel auf einer Palette oder einem Wagen abgelegt werden kann, ohne daß die Tragwalze dabei hinderlich ist.DE-OS 3 216 110 describes a winding machine with a winding axis mounted between power-operated winding levers, a pressure roller interacting with the winding axis and a support roller for the winding. In this winding machine, the pivoting movements of the winding levers and of pivoting levers for each winding diameter of the supporting roller are superimposed on one another. The swivel levers support the winding essentially from below. By continuing the pivoting movements of both the winding lever and the support roller beyond the winding area, the support roller and the winding are so far apart that the winding can be placed on a pallet or a trolley without the support roller being a hindrance.

Um einen bestimmten definierten Folienaufbau zu erreichen, ist es Stand der Technik, beim Wickeln einer Folienbahn die Zugkraft in der Folienbahn als konstant oder als Funktion der Zeit vorzugeben. Dies geschieht normalerweise durch Vorgabe eines bestimmten Drehmomentes für den Antriebsmotor der Wickelstation, auf deren Wickelkern gerade die Folienbahn aufgewickelt wird. So ist in der DE-OS 2 712 436 ein Verfahren zur kontinuierlichen Herstellung von biaxial orientiertem wärmefixiertem Polymerfilm bekannt, der einer Spannung ausgesetzt wird, die mindestens dreimal so groß wie die normale beim Filmtransport zwischen den Verstreckstationen und der Aufwickelstation auftretenden Spannung ist, während der Film bei einer Temperatur zwischen Raumtemperatur und dem Einfrierpunkt des Films gehalten wird. Der Polymerfilm wird der hohen Längsspannung zwischen dem Wärmefixieren und dem Aufwickeln ausgesetzt, wobei die Längsspannung mindestens die fünffache normale Transportspannung beträgt.In order to achieve a certain defined film structure, it is state of the art to specify the tensile force in the film web as constant or as a function of time when winding a film web. This is usually done by specifying a certain torque for the drive motor of the winding station, on the winding core of which the film web is being wound. For example, DE-OS 2 712 436 discloses a process for the continuous production of biaxially oriented heat-set polymer film which is subjected to a tension which is at least three times as great as the normal tension occurring during film transport between the stretching stations and the winding station, during which Film is kept at a temperature between room temperature and the freezing point of the film. The polymer film is subjected to the high longitudinal tension between heat setting and winding, the longitudinal tension being at least five times normal transport tension.

Der Wickelaufbau einer Rolle wird verbessert, wenn die Materialbahn um eine Anpreßwalze geführt wird, die selbst unmittelbar an dem Wickel mit einer vorgegebenen Anpreßkraft anliegt. Normalerweise beträgt der Umschlingungswinkel der Materialbahn für die Anpreßwalze 180°, wodurch bewirkt wird, daß die Zugkraft in der Materialbahn keine Komponente in Richtung oder entgegen der Richtung der Anpreßkraft aufweist. Die Anpreßkraft, mit der die Anpreßwalze in diesem Fall auf den Wickel drückt, ist dann gleich der Kraft, beispielsweise erzeugt durch einen Druckluftzylinder, der mit der Anpreßwalze verbunden ist, um die Anpreßwalze anzudrücken. Um die Zugkraft in der Materialbahn als auch die Kraft, mit der die Anpreßwalze auf den Wickel wirkt, konstant zu halten oder als Funktion der Zeit vorzugeben, werden beispielsweise Rechner eingesetzt, um die Kräfte zu regeln.The winding structure of a roll is improved if the material web is guided around a pressure roller which itself lies directly on the winding with a predetermined contact pressure. Normally, the wrap angle of the material web for the pressure roller is 180 °, which causes the tensile force in the material web to have no component in the direction of or against the direction of the pressure force. The pressure force with which the pressure roller presses on the roll in this case is then equal to the force, for example generated by a compressed air cylinder which is connected to the pressure roller in order to press the pressure roller. In order to keep the tensile force in the material web and the force with which the pressure roller acts on the winding constant or to specify it as a function of time, computers are used, for example, to regulate the forces.

Wendewickler, bei denen der Umschlingungswinkel um die Anpreßwalze 180° beträgt, sind häufig schlecht zu bedienen, da dieser Umschlingungswinkel Konstruktionen erfordert, die ein Durchfädeln der Materialbahn nur unter schwierigen Umständen zulassen.Turret winders, in which the wrap angle around the pressure roller is 180 °, are often difficult to operate, since this wrap angle requires constructions which only permit threading of the material web under difficult circumstances.

In der Praxis wird daher häufig ein Umschlingungswinkel kleiner als 180° angewandt, was zur Folge hat, daß eine Komponente der Kraft in Richtung bzw. entgegen der Richtung der Materialbahn entgegengesetzt zu der Anpreßkraft der Anpreßwalze an den Wickel wirkt. Es ist dann nur durch eine sehr aufwendige Steuerung möglich, die Anpreßkraft der Anpreßwalze so zu erhöhen, daß die Zugkraft in der Materialbahn in etwa kompensiert wird und eine fest vorgegebene Wickelspannung und fest vorgegebene Anpreßkraft eingehalten werden können.In practice, therefore, a wrap angle less than 180 ° is often used, with the result that a component of the force in the direction or counter to the direction of the material web acts counter to the contact pressure of the pressure roller on the roll. It is then only possible by means of a very complex control system to increase the contact pressure of the pressure roller in such a way that the tensile force in the material web is approximately compensated for and a fixedly specified winding tension and fixedly specified contact force can be maintained.

Aufgabe der Erfindung ist es, Materialbahnen mit vorgegebener Wickelspannung und vorgegebener Anpreßkraft zwischen dem Wickel und der Anpreßwalze, ohne aufwendige Steuerung, mit einfachen Mitteln auf einen Wickelkern einer Wickelstation eines Mehrfachwicklers aufzuwickeln.The object of the invention is to wind up material webs with a predetermined winding tension and a predetermined contact force between the winding and the pressure roller, without complex control, with simple means on a winding core of a winding station of a multiple winder.

Diese Aufgabe wird durch ein Verfahren nach dem Oberbegriff des Anspruchs 1 in der Weise gelöst, daß die Zugkraft Fb in der Materialbahn, die entgegengesetzt zu der Zugkraft in der Materialbahn ist, laufend gemessen und einer vorgegebenen Anpreßkraft Fp, mit der die Anpreßwalze an dem Wickel anliegt, zu einer Kraft F aufaddiert wird, mit der als Sollwert die Anpreßwalze gegen den Wickel angedrückt wird.This object is achieved by a method according to the preamble of claim 1 in such a way that the tensile force F b in the material web, which is opposite to the tensile force in the material web, is measured continuously and a predetermined contact pressure Fp with which the pressure roller on the Winding is present, is added to a force F, with which the pressure roller is pressed against the winding as a setpoint.

Weitere verfahrensmäßige Schritte für die Vorgabe der Anpreßkraft Fp der Anpreßwalze an den Wickel ergeben sich aus den Merkmalen der Verfahrensansprüche 2 bis 6.Further procedural steps for specifying the contact pressure Fp of the contact roller on the winding result from the features of process claims 2 to 6.

Die Vorrichtung zum Aufwickeln einer Materialbahn auf einen Wickelkern einer Wickelstation, bei der die Materialbahn durch eine Anpreßwalze an einen drehenden Wickel herangeführt ist und mit einem Umschlingungswinkel kleiner als 180° um die Anpreßwalze geführt ist, zeichnet sich dadurch aus, daß in Aufwickelrichtung der Materialbahn der Anpreßwalze eine stationäre Meßwalze vorgeschaltet ist, über die die Materialbahn geführt ist, um die Zugkraft Fb in der Materialbahn zu messen und daß die gemessene Kraft Fb mit der vorgegebenen Anpreßkraft Fp, die im Berührungspunkt von Anpreßwalze und Wickel der Wickelstation angreift, addiert wird, und die Summe beider Kräfte Fb, Fp die Kraft F ergibt, mit der die Anpreßwalze an den Wickel angedrückt wird.The device for winding a material web onto a winding core of a winding station, in which the material web is guided to a rotating winding by a pressure roller and is guided with a wrap angle of less than 180 ° around the pressure roller, is characterized in that the material web is wound in the winding direction The pressure roller is preceded by a stationary measuring roller over which the material web is guided in order to measure the tensile force F b in the material web and that the measured force F b is added to the predetermined pressure force Fp which acts at the point of contact between the pressure roller and the winding of the winding station , and the sum of both forces F b , Fp gives the force F with which the pressure roller is pressed onto the roll.

Die Weiterbildung der erfindungsgemäßen Vorrichtung ergibt sich aus den übrigen Ansprüchen 8 bis 14.The development of the device according to the invention results from the remaining claims 8 to 14.

Mit der Erfindung wird der Vorteil erzielt, die Kraft Fb nämlich die Wickelspannung, in der Materialbahn während des Wickelns ständig zu regeln und darüber hinaus die Anpreßkraft Fp zwischen Anpreßwalze und Wickel sehr schnell und sehr genau regeln zu können. Als weiterer Vorteil kommt eine leichte Bedienbarkeit der Anlage hinzu, d.h. ein leichtes Durchfädeln der Materialbahn durch die Walzen hindurch, da der Umschlingungswinkel der Materialbahn um die Anpreßwalze herum nur 90° beträgt.With the invention, the advantage is achieved that the force F b, namely the winding tension, in the material web during the winding is constantly regulated and, moreover, the pressure force Fp between the pressure roller and the winding can be regulated very quickly and very precisely. Another advantage is the ease of use of the system, ie easy threading of the material web through the rollers, since the wrap angle of the material web around the pressure roller is only 90 °.

In Figur 1 ist schematisch ein an sich bekannter Zweifach-Wendewickler 16 gezeigt, bei dem zwei Wickelkerne 4a,4b an den Enden einer Schwinge 19 angebracht sind, die schwenkbar am oberen Ende eines Stränders 18 gelagert ist. An der einen Seite des Ständers 18 befindet sich etwa in Höhe der Lagerung der Schwinge 19 eine Hilfsrolle 20, auf die eine Materialbahn 2, wie beispielsweise eine Folien- oder Papierbahn, unmittelbar nach dem Abschlagen eines Wickels 3 auf dem ersten Wickelkern 4a solange aufgewickelt wird, bis der leere, zweite Wickelkern 4b in die ursprüngliche Aufwickellage des ersten Wickelkerns 4a geschwenkt ist, in der eine Anpreßwalze 5 an dem sich ausbildenden Wickel anliegt. Sobald die Schwinge 19 geschwenkt wurde, kann der Wickel 3 von dem Wickelkern 4a, der sich dann in der Entnahmestellung befindet, abgenommen werden.FIG. 1 schematically shows a double-turn winder 16 known per se, in which two winding cores 4a, 4b are attached to the ends of a rocker 19 which is pivotably mounted on the upper end of a stretcher 18. On one side of the stand 18 there is an auxiliary roller 20 approximately at the level of the mounting of the rocker 19, onto which a material web 2, such as a film or paper web, is wound as long as a roll 3 is knocked off on the first winding core 4a until the empty, second winding core 4b is pivoted into the original winding position of the first winding core 4a, in which a pressure roller 5 lies against the winding that is being formed. As soon as the rocker 19 has been pivoted, the winding 3 can be removed from the winding core 4a, which is then in the removal position.

Die Anpreßwalze 5 ist an unteren Ende eines Trägers 12 befestigt, dessen oberes Ende mit einen Druckzylinder 13 verbunden ist. Der Druckzylinder 13 ist entlang einer Gleitschiene 22 verschiebbar, so daß stets sichergestellt ist, daß die Anpreßwalze 5 am Wickel 3 anliegt, unabhängig davon, wie groß der Durchmesser des Wickels 3 ist. Die Materialbahn 2 wird mit einem Umschlingungswinkel von 90° um eine Umlenkwalze 17 zu der Anpreßwalze 5 geführt und umschlingt diese mit einem Umschlingungswinkel von 180°. Von der Anpreßwalze 5 läuft die Folienbahn 2 auf den Wickel 3 auf, der mit einem Drehmoment Md des nicht gezeigten Antriebsmotors der Wickelstation angetrieben wird.The pressure roller 5 is attached to the lower end of a carrier 12, the upper end of which is connected to a pressure cylinder 13. The pressure cylinder 13 is displaceable along a slide rail 22, so that it is always ensured that the pressure roller 5 bears against the winding 3, regardless of how large the diameter of the winding 3 is. The material web 2 is guided with a wrap angle of 90 ° around a deflection roller 17 to the pressure roller 5 and wraps around it with a wrap angle of 180 °. The film web 2 runs from the pressure roller 5 onto the winding 3, which is driven with a torque M d of the drive motor of the winding station, not shown.

Der Umschlingungswinkel von 180° um die Anpreßwalze 5 herum bewirkt, daß die Zugkraft Fb in der Materialbahn 2 keine Komponente in Richtung order entgegen der Richtung der Anpreßkraft Fp hat. Die Anpreßkraft Fp, mit der die Anpreßwalze 5 an dem Wickel 3 anliegt, ist dann gleich der Kraft F, mit der der Druckzylinder 13, beispielsweise ein Druckluft- oder ein Hydraulikzylinder, die Anpreßwalze 5 gegen den Wickel 3 drückt.The wrap angle of 180 ° around the pressure roller 5 has the effect that the tensile force F b in the material web 2 has no component in the direction or against the direction of the pressure force Fp. The contact pressure Fp with which the contact roller 5 bears against the winding 3 is then equal to the force F with which the pressure cylinder 13, for example a compressed air or hydraulic cylinder, presses the contact roller 5 against the winding 3.

Sowohl die Kraft Fb in der Materialbahn 2 als auch die Kraft Fp, mit der die Anpreßwalze 5 auf den Wickel 3 wirkt, können konstant sein oder in Abhängigkeit von der Zeit vorgegeben werden, wofür entsprechende Rechner eingesetzt werden können.Both the force F b in the material web 2 and the force Fp with which the pressure roller 5 acts on the roll 3 can be constant or can be predetermined as a function of time, for which purpose suitable computers can be used.

Zweifach-Wendewickler 16, die mitAnpreßwalzen 5 ausgestattetsind, bei denen der Umschlingungswinkel der Materialbahn 2 um die Anpreßwalze 180° beträgt, lassen ein Durchfädeln der Materialbahn 2 bei Maschinenanfahrt oder nach Bahnabriß nur unter schwierigen Umständen zu. In der Praxis wird daher häufig auf den vollen Umschlingungswinkel von 180° verzichtet, was zur Folge hat, daß stets eine der Komponente der Kraft Fb entgegengesetzt zu der Anpreßkraft Fp wirkt. Es ist dann nur durch eine sehr aufwendige Steuerung möglich, die Kraft F so zu erhöhen, daß die Komponente der Kraft Fb in der Materialbahn in etwa kompensiert wird.Double turret winders 16, which are equipped with pressure rollers 5, in which the angle of wrap of the material web 2 around the pressure roller is 180 °, permit threading of the material web 2 when the machine starts up or after web breakage only under difficult circumstances. In practice, therefore, the full wrap angle of 180 ° is often dispensed with, which has the consequence that one of the components of the force F b always acts counter to the contact pressure Fp. It is then only possible through a very complex control to increase the force F in such a way that the component of the force F b in the material web is approximately compensated.

In Figur 2 ist eine Vorrichtung 1 nach der Erfindung zum Aufwickeln der Materialbahn 2 auf einen Wickelkern 4 einerWickelstation 9 gezeigt. Teile dieser Vorrichtung 1, die mit entsprechenden Teilen nach den Figuren 1 und 3 übereinstimmen, sind mit den gleichen Bezugszeichen belegt.FIG. 2 shows a device 1 according to the invention for winding the material web 2 onto a winding core 4 of a winding station 9. Parts of this device 1, the corresponding parts according to the figures 1 and 3 match, are given the same reference numerals.

Die Materialbahn 2 wird auf Leitwalzen 10 und 11 in Aufwickelrichtung C über eine Meßwalze 6 geführt, die der Anpreßwalze 5 vorgeschaltet ist. Die Meßwalze 6 ist auf Kraftmeßdosen 7 gelagert, die auf einem Ständer 8 angeordnet sind. In Figur 2 ist eine der Kraftmeßdosen 7 schematisch im oberen Teil des Ständers 8 angedeutet. Die Zugkraft Fb in der Materialbahn 2, wird mit Hilfe der Meßwalze 6 fortlaufend bestimmt. Die Materialbahn 2 wird horizontal über die Unterseite der Leitwalzen 10 und 11 geführt und steigt schräg nach oben zu der Meßwalze 6 an. Nach der Meßwalze 6 verläuft die Folienbahn 2 horizontal in Richtung der Anpreßwalze 5 und ist um diese mit einem Umschlingungswinkel von 90° herumgeführt und wird zu dem Wickel 3 mit einem Wickelradius R auf dem Wickelkern 4 aufgewickelt. Der Wickelradius R wird entweder laufend gemessen oder aus den Foliendaten Lauflänge, Dicke und Wickeldichte berechnet. Die Messung von R kann mit Hilfe eines nicht dargestellten Wegaufnehmers geschehen, der sich z.B. mit dem Träger 12 bewegt. Der Wickel 3 läuft mit einem Drehmoment Md im Gegenuhrzeigersinn um. Die fortlaufend gemessene Kraft Fb wird mit der vorgegebenen Anpreßkraft Fp, mit der die Anpreßwalze 5 gegen den Wickel 3 drücken soll, addiert, und die Summe der beiden Kräfte Fb und Fp ergibt den Sollwert der Kraft F, mit der die Anpreßwalze 5 in Richtung auf den Wickel gehalten wird.The material web 2 is guided on guide rollers 10 and 11 in the winding direction C over a measuring roller 6, which is connected upstream of the pressure roller 5. The measuring roller 6 is mounted on load cells 7, which are arranged on a stand 8. In Figure 2, one of the load cells 7 is indicated schematically in the upper part of the stand 8. The tensile force F b in the material web 2 is continuously determined using the measuring roller 6. The material web 2 is guided horizontally over the underside of the guide rollers 10 and 11 and rises obliquely upwards to the measuring roller 6. After the measuring roller 6, the film web 2 runs horizontally in the direction of the pressure roller 5 and is guided around it with a wrap angle of 90 ° and is wound onto the winding 3 with a winding radius R on the winding core 4. The winding radius R is either measured continuously or calculated from the film data, length, thickness and winding density. The measurement of R can take place with the aid of a displacement sensor, not shown, which moves with the carrier 12, for example. The winding 3 rotates counterclockwise with a torque M d . The continuously measured force F b is added to the predetermined contact pressure Fp with which the contact roller 5 is to press against the winding 3, and the sum of the two forces F b and Fp results in the desired value of the force F with which the contact roller 5 in Direction on the wrap is held.

Die Anpreßwalze 5 ist an dem unteren Ende des Trägers 12 befestigt, ebenso wie bei dem Zweifach-Wendewickler 16 nach Figure 1. Der Träger 12 steht mit dem Kolben des Druckzylinders 13 in Verbindung, der entlang der Gleitschiene 22 verschiebbar ist.The pressure roller 5 is fastened to the lower end of the carrier 12, as is the case with the double turret winder 16 according to FIG. 1. The carrier 12 is connected to the piston of the pressure cylinder 13, which can be moved along the slide rail 22.

Bei dem Druckzylinder 13 handelt es sich um einen Luftdruck- oder einen Hydraulikzylinder, dessen Mediumdruck durch das Ausgangssignal eines ersten Regelkreises 14 geregeltwird. In den Regelkreis 14 werden ein elektrisches Signal, das der durch die Kraftmeßdosen 7 bestimmten Kraft Fb entspricht, und ein weiteres elektrisches Signal eingespeist, das äquivalent der vorgegebenen Anpreßkraft Fp der Anpreßwalze 5 ist. Diese beiden elektrischen Signale werden zu dem Ausgangssignal des ersten Regelkreises 14 addiert, das dann in entsprechender Weise den Mediumdruck des Druckzylinders 13 so regelt, daß die Anpreßwalze 5 im Berührungspunkt A mit dem Wickel 3 die Kraft Fp auf den Wickel 3 ausübt. Die Kraft Fp ist der Sollwert, mit der die Anpreßwalze 5 gegen den Wickel 3 gedrückt wird.The pressure cylinder 13 is an air pressure or a hydraulic cylinder, the medium pressure of which is regulated by the output signal of a first control circuit 14. An electrical signal which corresponds to the force F b determined by the load cells 7 and a further electrical signal which is equivalent to the predetermined contact force Fp of the pressure roller 5 are fed into the control circuit 14. These two electrical signals are added to the output signal of the first control circuit 14, which then regulates the medium pressure of the printing cylinder 13 in such a way that the pressure roller 5 exerts the force Fp on the winding 3 at the point of contact A with the winding 3. The force Fp is the desired value with which the pressure roller 5 is pressed against the winding 3.

Des weiteren ist noch ein zweiter Regelkreis 15 vorhanden, den, dem das der gemessenen Kraft Fb entsprechende elektrische Signal der Kraftmeßdosen 7 eingespeist wird. In dem Regelkreis 15 wird dieses Signal mit einem zeitlich variablen/oder konstanten Signal des Sollwertes Fb verglichen, das dem vorgegebenen Drehmoment Md entspricht. Das vorgegebene Drehmoment Md ist gleich dem Sollwert des Drehmoments, und daraus wird gemäß der Gleichung Fb = Md/R der Sollwert Fb berechnet. Das Ausgangssignal des zweiten Regelkreises 15 wird dem nicht gezeigten Antriebsmotor der Wickelstation 9 zugleitet und regelt somit das Drehmoment Md des Wickels 3 in einer Weise, daß die auf die Materialbahn 2 ausgeübte Zugspannung Fb dem vorgegebenen Drehmoment Md entspricht.Furthermore, there is a second control circuit 15, which is fed with the electrical signal of the load cells 7 corresponding to the measured force F b . In the control circuit 15, this signal is compared with a time-variable / or constant signal of the target value F b , which corresponds to the predetermined torque M d . The predetermined torque M d is equal to the target value of the torque, and the target value F b is calculated from this in accordance with the equation F b = M d / R. The output signal of the second control circuit 15 is fed to the drive motor of the winding station 9, not shown, and thus regulates the torque M d of the winding 3 in such a way that the tensile stress F b exerted on the material web 2 corresponds to the predetermined torque M d .

Bei der Anordnung nach Figur 2 erlaubt der geringe Umschlingungswinkel von 90° der Materialbahn 2 um die Anpreßwalze 5, eine konstruktive Anordnung der Walzen des Wendewicklers, wenn es sich beispielsweise um einen Zweifach-Wendewickler nach Figur 1 oder um einen Dreifach-Wendewickler nach Figur 3 handelt, vorzunehmen, die eine leichte Bedienbarkeit, d.h. ein leichtes Durchfädeln der Materialbahn 2 gestattet.In the arrangement according to FIG. 2, the small wrap angle of 90 ° of the material web 2 around the pressure roller 5 permits a constructive arrangement of the rollers of the turret winder, for example if it is a double turret winder according to FIG. 1 or a triple turret winder according to FIG. 3 is to make, which is easy to use, ie easy threading of the material web 2 allowed.

Durch die Meßwalze 6, die auf den Kraftmeßdosen 7 des Ständers 8 gelagert ist, wird ständig die Kraft Fb in der Materialbahn 2 bestimmt. Diese Kraft wird mit derAnpreßkraft Fp, die im Berührungspunkt Azwischen der Anpreßwalze 5 und dem Wickel 3 wirkt, zu der Kraft F aufaddiert, die den Sollwert darstellt, mit der die Anpreßwalze 5 in Richtung auf den Wickel gehalten wird.The force F b in the material web 2 is continuously determined by the measuring roller 6, which is mounted on the load cells 7 of the stand 8. This force is added with the contact force Fp, which acts at the point of contact A between the contact roller 5 and the winding 3, to the force F, which represents the setpoint value with which the contact roller 5 is held in the direction of the package.

Wie schon voranstehend erwähnt ist, ermöglicht es die dargestellte Anordnung, eine Wickelcharakteristik, d.h. die Kraft Fb in der Materialbahn 2, als Funktion der Zeit vorzugeben. Dies geschieht durch die Vorgabe des Drehmoments Md, das konstant oder von der Zeit abhäng ig sein kann. Das konstante Drehmoment Md bzw. der gewünschte zeitliche Verlauf des Drehmoments Md kann auch mechanisch oder elektronisch abgespeichert und als Sollwert für eine Regelung vorgegeben werden. In diesem Fall kann dann der voranstehend beschriebene zweite Regelkreis 15 entfallen. Es ist auch möglich, den zeitlichen Verlauf der Kraft Fb in der Materialbahn 2 als Sollwert vorzugeben, indem die Wickelspannung bzw. die Zugkraft auf die Materialbahn 2 vorab festgelegt wird, und diesen Sollwert mit dem Meßwert der Kraft Fb, wie er von der Meßwalze 6 und den Kraftmeßdosen 7 festgestellt wird, zu vergleichen und den Antrieb der Wickelstation 9 bzw. das Drehmoment Md so zu regeln, daß Soll- und Meßwert übereinstimmen. Dies geschieht mit Hilfe des zweiten Regelkreises 15, wie dies voranstehend schon beschrieben wurde.As already mentioned above, the arrangement shown makes it possible to specify a winding characteristic, ie the force F b in the material web 2, as a function of time. This is done by specifying the torque M d , which can be constant or dependent on time. The constant torque M d or the desired time profile of the torque M d can also be stored mechanically or electronically and specified as a setpoint for a control. In this case, the second control circuit 15 described above can then be omitted. It is also possible, the time profile of the force F b to specify as a desired value in the web of material 2 by the winding tension and the pulling force is set to the material web 2 in advance, and b this desired value with the measured value of the force F, as determined by the Measuring roller 6 and the load cells 7 is determined to compare and to control the drive of the winding station 9 or the torque M d so that the target and measured values match. This is done with the help of the second control circuit 15, as has already been described above.

In Figur 3 ist ein Dreifach-Wendewickler 23 schematisch dargestellt, mit den an den Ecken eines Rollenwechslers 21, der eine dreiecksförmige Gestalt besitzt, drehbar gelagerten Wickelkernen 4a, 4b, 4c. Einer dieser Wickelkerne, nämlich der Wickelkern 4a, befindet sich in der Aufwickelstellung und trägt einen Wickel 3, gegen den die Anpreßwalze 5 im BerührungspunktAanliegt. Der Rollenwechsler21 ist mittig auf einem Ständer 18 gelagert und in Richtung des Pfeils B im Gegenuhrzeigersinn schwenkbar, so daß nach dem Abschlagen des Wickels 3, sobald dieser seine vorgegebene Größe erreicht hat, der nächste Wickelkern 4c in die Aufwikkelstellung gebracht werden kann.FIG. 3 schematically shows a triple turret winder 23 with the winding cores 4a, 4b, 4c, which are rotatably mounted at the corners of a reel changer 21, which has a triangular shape. One of these winding cores, namely the winding core 4a, is in the winding position and carries a winding 3 against which the pressure roller 5 rests at the contact point A. The reel changer 21 is mounted centrally on a stand 18 and can be pivoted in the direction of arrow B in the counterclockwise direction, so that after knocking off of the winding 3, as soon as it has reached its predetermined size, the next winding core 4c can be brought into the winding position.

Die Materialbahn 2 umschlingt die Anpreßwalze 5 mit einem Umschlingungswinkel von 90° und ist über die der Anpreßwalze 5 in Aufwickelrichtung R vorgelagerte Meßwalze 6 geführt, die auf Kraftmeßdosen 7 auf dem Ständer 8 gelagert ist.The material web 2 wraps around the pressure roller 5 with a wrap angle of 90 ° and is guided over the measuring roller 6 upstream of the pressure roller 5 in the winding direction R, which is mounted on load cells 7 on the stand 8.

Die Anpreßwalze 5 ist in dergleichen Artwie bei der Anordnung nach Figur am unteren Ende des Trägers 12 angebracht, der mit seinem oberen Ende mit einem nichtgezeigten Druckkolben des Druckzylinders 13 verbunden ist, der längs der Gleitschiene 22 horizontal hin und her verschiebbar ist. Die übrigen Teile dieser Anordnung, wie der erste und der zweite Regelkreis und die Leitwalzen, sind identisch mit den entsprechenden Teilen der Anordnung nach Figur 2 und wurden aus Vereinfachungsgründen weggelassen.The pressure roller 5 is attached in the same way as in the arrangement according to the figure at the lower end of the carrier 12, which is connected at its upper end to a pressure piston (not shown) of the pressure cylinder 13 which can be moved horizontally back and forth along the slide rail 22. The remaining parts of this arrangement, such as the first and the second control circuit and the guide rollers, are identical to the corresponding parts of the arrangement according to FIG. 2 and have been omitted for reasons of simplification.

Für die Regelung der Gesamtkraft F bzw. der Anpreßkraft Fp und die Messung der Kraft Fb in der Materialbahn 2 gilt das im Zusammenhang mit der Beschreibung der Figur 2 gesagte.What has been said in connection with the description of FIG. 2 applies to the regulation of the total force F or the contact pressure Fp and the measurement of the force F b in the material web 2.
