Description

Die Erfindung betrifft ein Verfahren zur Regelung eines Rollenwechslers einer Rollendruckmaschine nach dem Oberbegriff des Anspruchs 1. Weiterhin betrifft die Erfindung einen Rollenwechsler einer Rollendruckmaschine.The invention relates to a method for controlling a reel changer of a web-fed printing press according to the preamble of claim 1. Furthermore, the invention relates to a reel changer of a web-fed printing press.

Rollenwechsler von Rollendruckmaschinen übernehmen in erster Linie drei Hauptaufgaben, erstens das Abspulen einer Bedruckstoffbahn von einer Bedruckstoffrolle mit einer definierten Bahngeschwindigkeit, zweitens das Aufbringen einer definierten Bahnspannung auf die abzuspulende Bedruckstoffbahn und drittens die Ausführung eines Rollenwechsels zwischen einer auslaufenden Bedruckstoffrolle und einer neuen Bedruckstoffrolle. Rollenwechsler werden auch als Rollenträger bezeichnet. Beim Abspulen der Bedruckstoffbahn von der Bedruckstoffrolle steht das Einhalten der definierten Bahngeschwindigkeit sowie das Aufbringen der definierten Bahnspannung im Vordergrund. Soll hingegen ein Rollenwechsel zwischen einer auslaufenden Bedruckstoffrolle und einer neuen Bedruckstoffrolle ausgeführt werden, so muss die neue Bedruckstoffrolle auf die Umfangsgeschwindigkeit der auslaufenden Bedruckstoffrolle beschleunigt werden, um so die Bahngeschwindigkeiten der jeweiligen Bedruckstoffbahnen zu synchronisieren.Role changers of web presses take over primarily three main tasks, first, the unwinding of a substrate web from a Bedruckstoffrolle with a defined web speed, secondly the application of a defined web tension on abzuspulende substrate web and third, the execution of a roll change between a leaking Bedruckstoffrolle and a new Bedruckstoffrolle. Reel changers are also referred to as roller carriers. When unwinding the printing material web from the printing material roll is the maintenance of the defined path speed and the application of the defined web tension in the foreground. If, on the other hand, a reel change between an outgoing substrate roll and a new substrate roll is to be carried out, then the new substrate roll must be accelerated to the peripheral speed of the emerging substrate roll so as to synchronize the web speeds of the respective printing material webs.

Die Einhaltung einer definierten Bahngeschwindigkeit sowie einer definierten Bahnspannung der von der Bedruckstoffrolle abzuwickelnden Bedruckstoffbahn sowie das Beschleunigen einer neuen Bedruckstoffrolle auf die Umfangsgeschwindigkeit einer auslaufenden Bedruckstoffrolle beim Rollenwechsel erfolgt mithilfe eines Regelungsverfahrens.Compliance with a defined web speed and a defined web tension to be handled by the substrate roll substrate and the acceleration of a new Bedruckstoffrolle on the peripheral speed of a leaking Bedruckstofrolle when reel change using a control method.

Aus der Praxis ist es bereits bekannt, zur Regelung der Drehzahl eines eine Bedruckstoffrolle antreibenden Motors und damit zur Regelung der Umfangsgeschwindigkeit der Bedruckstoffrolle bzw. der Bahngeschwindigkeit der abzuwickelnden Bedruckstoffbahn einen Kaskadenregelkreis aus einer Stromregelung und einer der Stromregelung überlagerten Drehzahlregelung einzusetzen. Weiterhin ist es aus der Praxis bekannt, die definierte Bahnspannung durch eine Tänzerwalze bereitzustellen, die mit einer definierten Kraft in eine Schlaufe der von der Bedruckstoffrolle abgewickelten Bedruckstoffbahn drückt. Die Tänzerwalze soll dabei über eine Lageregelung in einer Mittellage gehalten werden, d.h. dass die Bahngeschwindigkeit der Bedruckstoffbahn vor bzw. stromaufwärts der Tänzerwalze der Bahngeschwindigkeit der Bedruckstoffbahn nach bzw. stromabwärts der Tänzerwalze entsprechen soll. Hierzu ist dem Kaskadenregelkreis aus der Stromregelung und Drehzahlregelung im Sinne einer weiteren Kaskade eine Lagerregelung überlagert, welche die Tänzerwalze in der definierten Mittellage hält.From practice it is already known to use a cascade control loop from a current control and a speed control superimposed on the current control for controlling the speed of a motor driving a Bedruckstoffrolle engine and thus to control the peripheral speed of the Bedruckstoffrolle or the web speed of the unwinding. Furthermore, it is known from practice to provide the defined web tension by a dancer roller which presses with a defined force in a loop of the unwound from the Bedruckstoffrolle substrate web. The dancer roller is to be held via a position control in a central position, i. the web speed of the printing material web before or upstream of the dancer roller should correspond to the web speed of the printing material web after or downstream of the dancer roller. For this purpose, a storage control is superimposed on the cascade control loop from the current control and speed control in terms of another cascade, which keeps the dancer roller in the defined center position.

Das obige, aus dem Stand der Technik bekannte Regelkonzept für einen Rollenwechsler neigt zu Schwingungen, welche die Regelgüte negativ beeinträchtigen. Dies liegt unter anderem darin begründet, dass sowohl die Bedruckstoffrolle als auch die Tänzerwalze durch ein integrales Regelungsverhalten gekennzeichnet sind, was letztendlich zu Regelschwingungen führen kann.The above, known from the prior art control concept for a reel splitter tends to oscillate, which negatively affect the control performance. This is partly due to the fact that both the printing material roller and the dancer roller are characterized by an integral control behavior, which can ultimately lead to control vibrations.

Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zugrunde, ein neuartiges Verfahren zur Regelung eines Rollenwechslers einer Rollendruckmaschine sowie einen neuartigen Rollenwechsler zu schaffen.On this basis, the present invention is based on the problem to provide a novel method for controlling a reel changer of a web-fed printing press and a novel reel splicer.

Dieses Problem wird durch ein Verfahren zur Regelung eines Rollenwechslers einer Rollendruckmaschine gemäß Anspruch 1 gelöst. Erfindungsgemäß wird bei einem Rollenwechsel zur Synchronisation der Umfangsgeschwindigkeit einer neuen Bedruckstoffrolle auf die Umfangsgeschwindigkeit der auslaufenden Bedruckstoffrolle die Lageregelung der Tänzerwalze deaktiviert und zur Bildung eines Sollwerts der Stromregelung einer Ausgangsgröße der Drehzahlregelung als Vorsteuerkomponente der differenzierte Sollwert der Drehzahlregelung aufgeschaltet; nach erfolgtem Rollenwechsel wird im Lauf bzw. beim Abwickeln der Bedruckstoffbahn die Lageregelung der Tänzerwalze aktiviert und zur Bildung des Sollwerts der Stromregelung der Ausgangsgröße der Drehzahlregelung als Vorsteuerkomponente der differenzierte Istwert der Lageregelung aufgeschaltet.This problem is solved by a method for controlling a reel changer of a web-fed printing press according to claim 1. According to the invention, the position control of the dancer roller is deactivated in the case of a reel change to synchronize the peripheral speed of a new printing material roll to the peripheral speed of the outfeed printing material roll and to form a nominal value of the current regulation of an output variable of the rotational speed control as pre-control component the differentiated setpoint of the speed control is activated; after the roll change, the position control of the dancer roller is activated during the run or when unwinding the printing material web and switched to form the target value of the current control of the output of the speed control as a pilot component of the differentiated actual value of the position control.

Im Sinne der hier vorliegenden Erfindung wird vorgeschlagen, beim Rollenwechsel und bei deaktivierter Lageregelung der Tänzerwalze bei der Bildung des Sollwerts für die Stromregelung des Kaskadenregelkreises aus Stromregelung und Drehzahlregelung als Vorsteuerkomponente das zeitliche Differential des Sollwerts der Drehzahlregelung zu verwenden. Nach erfolgtem Rollenwechsel wird bei aktivierter Lageregelung der Tänzerwalze bei der Bildung des Sollwerts der Stromregelung als Vorsteuerkomponente das zeitliche Differential des Istwerts der Lageregelung verwendet. Hierbei kann sowohl beim Rollenwechsel als auch nach erfolgten Rollenwechsel Regelschwingungen entgegengewirkt werden, wodurch sich ein gutes Regelverhalten erzielen lässt. Weiterhin ist ein robustes Regelverhalten realisierbar, welches gegenüber Fehlanpassungen zwischen dem Motor und der Bedruckstoffrolle, wie es bei großen Bedruckstoffrollen auftreten kann, unempfindlich ist. Bei großen Massenträgheiten der Bedruckstoffrollen können relativ kleine Motoren mit geringer Leistung verwendet werden. Die ist ein weiterer, ökonomischer Vorteil des erfindungsgemäßen Verfahrens.For the purposes of the present invention, it is proposed to use the time differential of the desired value of the speed control when changing roles and when the position control of the dancer roller is deactivated in the formation of the set value for the current control of the cascade control circuit from current control and speed control. After the roll change has been made, when the position control of the dancer roller is activated, the time differential of the actual value of the position control is used as the precontrol component in forming the desired value of the current control. This can be counteracted both when reel change and after the roll change control oscillations, whereby a good control behavior can be achieved. Furthermore, a robust control behavior can be realized, which is insensitive to mismatches between the engine and the Bedruckstoffrolle, as it may occur in large Bedruckstoffrollen. With large inertia of the printing material rollers relatively small motors with low power can be used. This is another economic advantage of the method according to the invention.

Der erfindungsgemäße Rollenwechsler einer Rollendruckmaschine ist in Anspruch 6 definiert.The reel changer according to the invention of a web-fed printing press is defined in claim 6.

Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung. Ein Ausführungsbeispiel der Erfindung wird, ohne hierauf beschränkt zu sein, an Hand der Zeichnung näher erläutert. Dabei zeigt:

Preferred embodiments of the invention will become apparent from the dependent claims and the description below. An embodiment of the invention will be described, without being limited thereto, with reference to the drawing. Showing:
Fig. 1:
a block diagram for illustrating the inventive method for controlling a roll changer a web press.

Nachfolgend wird die hier vorliegende Erfindung unter Bezugnahme auf Fig. 1 in größerem Detail beschrieben.Hereinafter, the present invention will be described with reference to FIG Fig. 1 described in more detail.

Fig. 1 zeigt ein Blockschaltbild einer erfindungsgemäßen Regelstruktur für einen Rollenwechsler einer Rollenrotationsdruckmaschine, wobei gemäß Fig. 1 von einer Bedruckstoffrolle 10 im Sinne des Pfeils 11 eine Bedruckstoffbahn 12 abgewickelt wird, die im Sinne des Pfeils 13 einer Rollenrotationsdruckmaschine zugeführt wird. Die Bedruckstoffrolle 10 ist auf einem im Detail nicht-dargestellten Rollenwechsler gelagert, wobei ein Rollenwechsler auch als Rollenträger bezeichnet wird. Die Bedruckstoffrolle 10 wird von einem Motor 14 angetrieben, wobei aus der Drehzahl des Motors 14 und dem Radius bzw. Durchmesser der Bedruckstoffrolle 10 die Umfangsgeschwindigkeit der Bedruckstoffrolle 10 und damit die Bahngeschwindigkeit der abzuwickelnden Bedruckstoffbahn 12 errechnet werden kann. Da sich der Radius der Bedruckstoffrolle 10 beim Abwickeln der Bedruckstoffbahn 12 ändert, muss zur Einhaltung einer konstanten Bahngeschwindigkeit die Drehzahl des Motors 14 laufend angepasst werden. Fig. 1 shows a block diagram of a control structure according to the invention for a reel changer of a web-fed rotary printing press, wherein according to Fig. 1 from a printing material roll 10 in the direction of the arrow 11, a printing material web 12 is unwound, which is fed in the direction of the arrow 13 of a web-fed rotary printing press. The printing material roll 10 is mounted on a roll changer, not shown in detail, wherein a roll changer is also referred to as a roll carrier. The Bedruckstoffrolle 10 is driven by a motor 14, wherein from the rotational speed of the motor 14 and the radius or diameter of the Bedruckstoffrolle 10, the peripheral speed of Bedruckstoffrolle 10 and thus the web speed of the unwinding substrate web 12 can be calculated. Since the radius of the printing material roll 10 changes during unwinding of the printing material web 12, the rotational speed of the motor 14 must be constantly adapted to maintain a constant web speed.

Die von der Bedruckstoffrolle 10 abgewickelte Bedruckstoffbahn 12 wird an Walzen 15, 16 und 17 unter Bildung einer Schlaufe 18 geführt, wobei es sich bei den Walzen 15 und 17 um Umlenkrollen und bei der Walze 16 um eine sogenannte Tänzerwalze handelt. Die Tänzerwalze 16 drückt im Sinne des Pfeils 19 mit einer bestimmten Kraft in die Schlaufe 18, um eine definierte Bahnspannung bereitzustellen. Die Bahngeschwindigkeit der Bedruckstoffbahn 12 soll vor bzw. stromaufwärts der Tänzerwalze 16 genauso groß sein wie nach bzw. stromabwärts der Tänzerwalze 16. Ist dies der Fall, so befindet sich die Tänzerwalze 16 in der in Fig. 1 dargestellten Mittellage. Tritt hingegen an der Tänzerwalze 16 eine Differenzgeschwindigkeit auf, so wird die Tänzerwalze 16 im Sinne des Doppelpfeils 20 gegenüber dieser Mittellage entweder nach oben oder nach unten ausgelenkt. Dies soll vermieden werden.The unwound from the Bedruckstoffrolle 10 substrate web 12 is guided on rollers 15, 16 and 17 to form a loop 18, wherein it is the rollers 15 and 17 to deflection rollers and the roller 16 is a so-called dancer roller. The dancer roller 16 presses in the direction of the arrow 19 with a certain force in the loop 18 to provide a defined web tension. The web speed of the printing material web 12 should be as large as before or upstream of the dancer roller 16 as well as after or downstream of the dancer roller 16. If this is the case, then the dancer roller 16 is in the in Fig. 1 illustrated middle position. If, on the other hand, a differential speed occurs at the dancer roller 16, then the dancer roller 16 becomes in the sense of the double arrow 20 deflected either up or down towards this central position. This should be avoided.

Ziel der in Fig. 1 dargestellten Regelstruktur ist es, die Bedruckstoffbahn 10 mit einer definierten Bahngeschwindigkeit von der Bedruckstoffrolle 10 abzuwickeln und dabei die Tänzerrolle 16 in ihrer Mittellage zu halten, sodass an der Tänzerwalze 16, welche die Bahnspännung an der Bedruckstoffbahn 12 erzeugt, keine Differenzgeschwindigkeit auftritt.Goal of in Fig. 1 The illustrated control structure is to unwind the printing substrate 10 at a defined web speed of the Bedruckstoffrolle 10 while keeping the dancer roller 16 in its central position, so that at the dancer roller 16, which generates the Bahnspännung on the printing material 12, no differential speed occurs.

Zur Regelung der Umfangsgeschwindigkeit der Bedruckstoffrolle 10 und damit der Bahngeschwindigkeit der Bedruckstoffbahn 12 wird die Drehzahl des die Bedruckstoffrolle 10 antreibenden Motors 14 mithilfe eines Kaskadenregelkreises aus einer Stromregelung 21 und einer der Stromregelung 21 überlagerten Drehzahlregelung 22 geregelt. Gemäß Fig. 1 wird ein Sollwert 23 für die Bahngeschwindigkeit der Bedruckstoffbahn 12 und damit für die Umfangsgeschwindigkeit der Bedruckstoffrolle 10 vorgegeben, wobei dieser Sollwert 23 zur Bereitstellung eines Sollwerts 24 für die Drehzahlregelung 22 des Motors 14 mit einer Hilfsgröße 25 verrechnet wird. Bei der Hilfsgröße 25 handelt es sich um den Durchmesser der Bedruckstoffrolle 10, der sich, wie bereits erwähnt, während des Abspulens der Bedruckstoffbahn 12 von der Bedruckstoffrolle 10 laufend ändert. Der Sollwert 24 für die Drehzahlregelung 22 wird mit einem am Motor 14 erfassten Istwert 26 der Motordrehzahl verrechnet, wobei die Drehzahlregelung 22 eine Ausgangsgröße 27 bereitstellt, aus der ein Sollwert 28 für die Stromregelung 21 generiert bzw. ermittelt wird.To control the peripheral speed of the printing material roll 10 and thus the web speed of the printing material web 12, the speed of the printing material 10 driving motor 14 is controlled by means of a cascade control circuit from a current control 21 and the current control 21 superimposed speed control 22. According to Fig. 1 is a setpoint 23 for the web speed of the printing substrate 12 and thus set for the peripheral speed of the Bedruckstoffrolle 10, wherein this target value 23 is offset to provide a setpoint 24 for the speed control 22 of the motor 14 with an auxiliary size 25. In the auxiliary size 25 is the diameter of Bedruckstoffrolle 10, which, as already mentioned, during the unwinding of the printing substrate 12 of the Bedruckstoffrolle 10 changes continuously. The setpoint value 24 for the speed control 22 is offset with an actual value 26 of the motor speed detected at the motor 14, wherein the speed control 22 provides an output variable 27 from which a desired value 28 for the current control 21 is generated or determined.

Dem Kaskadenregelkreis aus der Stromregelung 21 und der Drehzahlregelung 22 ist im Sinne einer weiteren Kaskade eine Lageregelung 29 für die Tänzerwalze 16 überlagert. Mithilfe der Lageregelung 29 soll die Tänzerwalze 16, die der Bereitstellung einer definierten Bahnspannung dient, in ihrer Mittellage gehalten werden, sodass demnach an der Tänzerwalze 16 keine Differenzgeschwindigkeit auftritt. Die Bahngeschwindigkeit vor der Tänzerwalze 16 soll also genauso groß sein wie die Bahngeschwindigkeit nach der Tänzerwalze 16. Hierzu wird die Lage der Tänzerwalze 16 mithilfe eines Sensors 30 überwacht, und ein entsprechender Istwert 36 wird der Lageregelung 29 zugeführt.The cascade control loop from the current control 21 and the speed control 22 is in the sense of another cascade a position control 29 for the dancer roller 16 superimposed. With the aid of the position control 29, the dancer roller 16, which serves to provide a defined web tension, is held in its middle position, so that, accordingly, no differential speed occurs at the dancer roller 16. The web speed in front of the dancer roller 16 should therefore be the same as the web speed after the dancer roller 16. For this purpose, the position of the dancer roller 16 is monitored by means of a sensor 30, and a corresponding actual value 36 is the position control 29 is supplied.

Stromregelung 21 und Drehzahlregelung 22 werden vorzugsweise über PI-Regler realisiert. Die Lagerregung 29 hingegen ist vorzugsweise über einen PID-Regler ausgeführt. Der I-Anteil der als PID-Regler ausgeführten Lageregelung 29 sorgt dafür, dass auch bei falscher Hilfsgröße 25, also bei unrichtig bestimmtem Durchmesser der Bedruckstoffrolle 10, eine exakte Mittellage der Tänzerwalze 16 eingehalten werden kann.Current control 21 and speed control 22 are preferably realized via PI controller. The bearing excitation 29, however, is preferably carried out via a PID controller. The I component of the position control 29 embodied as a PID controller ensures that an exact central position of the dancer roller 16 can be maintained even if the auxiliary auxiliary size 25 is incorrect, that is, if the diameter of the printing material roll 10 is incorrect.

Gemäß Fig. 1 ist die Lageregelung 29 der Tänzerwalze 16 über einen Schalter 31 aktivierbar sowie deaktivierbar. Zur Ausführung eines Rollenwechsels ist die Lageregelung 29 der Tänzerwalze 16 deaktiviert, nach erfolgtem Rollenwechsel hingegen aktiviert. Fig. 1 zeigt die Regelstruktur mit geöffnetem Schalter 31, also in einem zur Durchführung eines Rollenwechsels vorliegenden Zustand.According to Fig. 1 the position control 29 of the dancer roller 16 can be activated and deactivated via a switch 31. To perform a roll change the position control 29 of the dancer roller 16 is deactivated, activated after a roll change, however. Fig. 1 shows the control structure with open switch 31, ie in a present to perform a roll change state.

Bei bzw. zur Durchführung eines Rollenwechsels wird zur Bildung des Sollwerts 28 für die Stromregelung 21 der Ausgangsgröße 27 der Drehzahlregelung 22 das zeitliche Differential des Sollwerts 24 der Drehzahlregelung 22 aufgeschaltet. So zeigt Fig. 1 ein Differentiationsglied 32, welchem beim Rollenwechsel bedingt durch die Stellung des Schalters 33 als Eingangsgröße der Sollwert 24 der Drehzahlregelung 22 zugeführt wird, wobei das Differentiationsglied 32 dann als Ausgangsgröße 34 das zeitliche Differential des Sollwerts 24 der Drehzahlregelung 22 bereitstellt. Die Ausgangsgröße 34 wird mit einer Hilfsgröße 35 verrechnet, nämlich multipliziert und anschließend auf die Ausgangsgröße 27 der Drehzahlregelung 22 addiert, um so den Sollwert 28 der Stromregelung 21 zu bilden. Bei der Hilfsgröße 35 handelt es sich um die dritte Potenz des Radius der Bedruckstoffrolle 10 multipliziert mit der Rollenbreite derselben.When or to carry out a roll change the time differential of the setpoint 24 of the speed control 22 is switched to form the setpoint value 28 for the current control 21 of the output variable 27 of the speed control 22. So shows Fig. 1 a Differentiationsglied 32, which is supplied to the role change due to the position of the switch 33 as input of the setpoint value 24 of the speed control 22, wherein the Differentiationsglied 32 then as output 34, the time differential of the setpoint 24 of the speed control 22 provides. The output variable 34 is offset with an auxiliary variable 35, namely multiplied and then added to the output variable 27 of the speed control 22, so as to form the set value 28 of the current control 21. The auxiliary size 35 is the third power of the radius of the printing material roll 10 multiplied by the roll width of the same.

Zur Durchführung eines Rollenwechsels und demnach zur Synchronisation der Umfangsgeschwindigkeit einer neuen Bedruckstoffrolle an die Umfangsgeschwindigkeit der auslaufenden Bedruckstoffrolle wird demnach bei deaktivierter Lageregelung 29 der Tänzerwalze 16 die Drehzahlregelung 22 des Motors 14 dadurch entlastet, dass der Stromregelung 21 eine Vorsteuerkomponente bereitgestellt wird, wobei es sich bei der Vorsteuerkomponente dann um das zeitliche Differential des Sollwerts 24 der Drehzahlregelung 22 handelt. Hierdurch wird eine Momentvorsteuerung beim Rollenwechsel bereitgestellt, sodass eine Geschwindigkeitsänderung der Druckmaschine oder eine Sollwertrampe beim Synchronisieren der Umfangsgeschwindigkeit von neuer Bedruckstoffrolle zu auslaufender Bedruckstoffrolle relativ exakt vorgesteuert werden kann, wodurch einer Schwingungsneigung entgegengewirkt wird.To carry out a roll change and thus to synchronize the peripheral speed of a new Bedruckstoffrolle to the peripheral speed of the outgoing Bedruckstoffrolle is thus deactivated when the position control 29 of the dancer roller 16, the speed control 22 of the motor 14, characterized in that the flow control 21, a pilot component is provided, which is at the pilot component is then the time differential of the setpoint value 24 of the speed control 22. As a result, a torque feedforward control is provided during the roll change, so that a change in speed of the printing machine or a setpoint ramp when synchronizing the peripheral speed of the new bed of material to expiring Bedruckstoffrolle can be precompressed relatively accurately, whereby a tendency to oscillate is counteracted.

Nach erfolgtem Rollenwechsel wird im Sinne der Erfindung die Regelstrategie dadurch geändert, dass beide Schalter 31 und 33 der Fig. 1 umgelegt werden, es wird demnach durch Schließen des Schalters 31 die Lageregelung 29 der Tänzerwalze 16 aktiviert, weiterhin wird durch Umlegen des Schalters 33 dem Sollwert 28 der Stromregelung 31 eine veränderte Vorsteuerkomponente aufgeschaltet.After the roll change, the control strategy is changed in the sense of the invention characterized in that both switches 31 and 33 of the Fig. 1 Accordingly, the position control 29 of the dancer roller 16 is activated by closing the switch 31, and by switching the switch 33, the setpoint value 28 of the current control 31 is switched to a modified pilot control component.

Nach erfolgtem Rollenwechsel wird nämlich als Vorsteuerkomponente für die Stromregelung 21 das zeitliche Differential der Ausgangsgröße 36 des Sensors 30 bereitgestellt. Bei der Ausgangsgröße 36 des Sensors 30 handelt es sich um den Istwert der Lageregelung 29 der Tänzerwalze 16. Nach erfolgtem Rollenwechsel wird demnach bei aktivierter Lageregelung 29 zur Bildung des Sollwerts 28 der Stromregelung 21 der Ausgangsgröße 27 der Drehzahlregelung 22 als Vorsteuerkomponente der differenzierte Istwert 36 der Lageregelung 29 aufgeschaltet. Auch in diesem Fall wird das vom Differentiationsglied 32 bereitgestellte Ausgangssignal 34 mit der Hilfsgröße 35 verrechnet, bei der es sich wiederum um die dritte Potenz des Radius der Bedruckstoffrolle multipliziert mit der Rollenbreite derselben handelt.After the role has been changed, the time differential of the output variable 36 of the sensor 30 is provided as a pre-control component for the current regulation 21. With the output variable 36 of the sensor 30 is the actual value of the position control 29 of the dancer roller 16. After the roll change is thus activated with attitude control 29 to form the setpoint 28 of the current control 21 of the output variable 27 of the speed control 22 as a pilot component of the differentiated actual value 36 of Position control 29 switched. In this case too, the output signal 34 provided by the differentiation element 32 is offset with the auxiliary quantity 35, which in turn is the third power of the radius of the printing material roll multiplied by the roll width of the same.

Durch die erfindungsgemäße Umstellung der Vorsteuerkomponente nach erfolgtem Rollenwechsel auf das zeitliche Differential des Lagesignals der Tänzerwalze kann die Schwingungsneigung der Tänzerwalze reduziert werden. So wird die Tänzerwalze mit dem erfindungsgemäßen Regelungsverfahren zu deutlich weniger Regelschwingungen angeregt. Weiterhin steigt die Robustheit der Regelung gegenüber Parameterungenauigkeiten bzw. Parameterfehlern im Regelkreis und gegenüber möglichen Störgrößen.Due to the inventive conversion of the pilot component after a roll change to the time differential of the position signal of the dancer roller, the tendency to vibration of the dancer roller can be reduced. Thus, the dancer roller is excited with the control method according to the invention to significantly less control vibrations. Furthermore, the robustness of the control increases with respect to parameter inaccuracies or parameter errors in the control loop and with respect to possible disturbance variables.

Abschließend sei darauf hingewiesen, dass das erfindungsgemäße Verfahren nicht nur beim Abwickeln einer Bedruckstoffbahn von einer Bedruckstoffrolle sondern analog auch beim Aufwickeln oder Umwickeln verwendet werden kann.Finally, it should be pointed out that the method according to the invention can be used not only when unwinding a printing material web from a printing substrate roll but also during winding or wrapping.
