Vorrichtung und Verfahren zum Reinigen eines Zylinders oder einer Walze einer DruckmaschineDevice and method for cleaning a cylinder or roller of a printing press

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Reinigen eines Zylinders oder einer Walze einer Druckmaschine mit einer Reinigungsmittelbahn, wobei für die Reinigungsmittelbahn eine erste Vorratsrolle zum Abspulen der Reinigungsmittelbahn und eine zweite Vorratsrolle zum Aufspulen der Reinigungsmittelbahn vorgesehen ist, wobei eine Spuleinrichtung zum abschnittsweisen Vorschub der Reinigungsmittelbahn mit einer Antriebseinrichtung drehbeweglich antreibbar ist, wobei eine Messeinrichtung vorgesehen ist, die den Radius mindestens einer Vorratsrolle erfasst und wobei eine Stelleinrichtung vorgesehen ist, womit der Betrag einer jeweiligen Drehbewegung der Spuleinrichtung in Abhängigkeit des erfassten Radius der Vorratsrolle veränderbar ist .The invention relates to a device and a method for cleaning a cylinder or a roller of a printing press with a cleaning agent web, a first supply roll for unwinding the cleaning agent web and a second supply roll for winding up the cleaning agent web being provided for the cleaning agent web, a winding device for feeding the section by section Detergent web is rotatably drivable with a drive device, a measuring device is provided which detects the radius of at least one supply roll and an adjusting device is provided, with which the amount of a respective rotary movement of the winding device can be changed as a function of the detected radius of the supply roll.

Solche Reinigungsvorrichtungen werden an Druckmaschinen eingesetzt, um überschüssige Betriebsmittel, beispielsweise überschüssige Druckfarbe, von einem Zylinder oder einer Walze abzunehmen. Die Begriffe Zylinder und Walze sollen deshalb nachfolgend als Synonyme verwendet werden.Such cleaning devices are used on printing presses in order to remove excess operating materials, for example excess printing ink, from a cylinder or a roller. The terms cylinder and roller should therefore be used as synonyms below.

Aus der DE 43 06 676 AI ist eine derartige Reinigungsvorrichtung mit zwei Spindeln bekannt, wobei auf der einen Spindel die Vorratsrolle mit der sauberen Reinigungsmittelbahn und auf der anderen Spindel die Abfallrolle mit der verbrauchten Reinigungsmittelbahn gelagert ist. Zum Antrieb der Spindeln sind Elektromotoren vorgesehen, so dass die Reinigungsmittelbahn entsprechend einem Steuerungsprogramm abschnittsweise weitergefördert und schließlich nach vollständigem Verbrauch der Vorratsrolle zurückgespult werden kann. Aus der US 5,275,104 ist ebenfalls eine Reinigungsvorrichtung bekannt, bei der die Abfallrolle durch einen Elektromotor schrittweise und im Dauerbetrieb angetrieben wird, während die Reinigungsbahn durch eine Walze pneumatisch gegen einen zu reinigenden Zylinder gedrückt wird.Such a cleaning device with two spindles is known from DE 43 06 676 AI, with the supply roll with the clean detergent web being stored on one spindle and the waste roll with the used detergent web on the other spindle. Electric motors are provided for driving the spindles, so that the cleaning agent web can be conveyed in sections according to a control program and finally rewound after the supply roll has been completely used up. A cleaning device is also known from US Pat. No. 5,275,104, in which the waste roll is driven step by step and in continuous operation by an electric motor, while the cleaning track is pressed pneumatically against a cylinder to be cleaned by a roller.

Aus der DE 41 42 422 AI ist eine weitere Reinigungsvorrichtung zur Führung einer Reinigungsmittelbahn bekannt . Bei dieser Vorrichtung wird die Reinigungsmittelbahn mit wechselnder Anpressung des Anstellkörpers gegen den entsprechenden Zylinder angedrückt, um dadurch einen quasi kontinuierlichen Vorschub zu gewährleisten.From DE 41 42 422 AI another cleaning device for guiding a cleaning agent web is known. In this device, the cleaning agent web is pressed against the corresponding cylinder with alternating pressing of the adjusting body, in order thereby to ensure a quasi-continuous feed.

Nachteilig an diesen bekannten Vorrichtungen ist es, dass sich der Vorschub der Reinigungsmittelbahn in Abhängigkeit des Radius der Abfallrolle ändert. Dies führt dazu, dass bei einer Abfallrolle mit großem Radius mit jedem abschnittsweisen Vorschub der Reinigungsmittelbahn mehr Reinigungsmittelbahn als zur Reinigung der Walze oder des Zylinders erforderlich weitergefördert wird. Dieser unnötige Verbrauch von Reinigungsmittelbahn führt zu relativ hohen Betriebskosten.A disadvantage of these known devices is that the feed of the cleaning agent web changes depending on the radius of the waste roll. As a result, in the case of a waste roll with a large radius, with each section-wise advance of the cleaning agent web, more cleaning agent web is conveyed on than is necessary for cleaning the roller or the cylinder. This unnecessary consumption of detergent web leads to relatively high operating costs.

Weiter ist aus der US 5,150,650 eine Reinigungsvorrichtung der eingangs genannten Art bekannt, bei der die Spuleinrichtung zum Aufspulen der Abfallrolle mehrmals pro Reinigungsvorgang pneumatisch angetrieben wird, um dadurch den Vorschub der Reinigungsmittelbahn zu gewährleisten, während sie über einen Kreisbogen an dem zu reinigenden Zylinder angedrückt bleibt. Jeder Reinigungsvorgang verbraucht eine grosse Länge der Reinigungsmittelbahn.Furthermore, from US 5,150,650 a cleaning device of the type mentioned is known, in which the winding device for winding the waste roll is pneumatically driven several times per cleaning process, in order to thereby ensure the advancement of the cleaning agent web, while it remains pressed onto the cylinder to be cleaned via an arc , Each cleaning process consumes a large length of the detergent path.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren zum Reinigen eines Zylinders oder einer Walze einer Druckmaschine zu schaffen, wobei der Verbrauch an Reinigungsmittelbahn so gering wie möglich gehalten wird.The invention has for its object to provide a device and a method for cleaning a cylinder or a roller of a printing press, the consumption of cleaning agent web as low as possible is held.

Die Aufgabe wird erfindungsgemäß durch eine Vorrichtung der eingangs genannten Art gelöst, bei der die Reinigungsmittelbahn mittels einer Andrückeinrichtung gegen den Umfang des Zylinders oder der Walze andrückbar ist, wobei die Andrückeinrichtung auch mittels der Antriebseinrichtung zwischen einer angestellten Arbeitsposition und einer abgestellten Ruheposition verstellbar ist.The object is achieved according to the invention by a device of the type mentioned at the outset, in which the cleaning agent web can be pressed against the circumference of the cylinder or the roller by means of a pressing device, the pressing device also being adjustable between an employed working position and a parked rest position by means of the drive device.

Erfindungsgemäss wird ein Verfahren ausgeführt, wobei die Reinigungsmittelbahn von einer ersten Vorratsrolle abgespult und auf einer zweiten Vorratsrolle taktweise aufgespult wird, wobei die Reinigungsmittelbahn pro Arbeitstakt um eine annähernd konstante Länge weitertransportiert wird, wobei die Reinigungsmittelbahn pro Arbeitstakt jeweils zwischen einer an dem Zylinder oder der Walze angestellten Arbeitsposition und einer abgestellten Ruheposition verstellt wird, und wobei der jeweilige Weitertransport ausschließlich bei der Anstellbewegung oder ausschließlich bei der Abstellbewegung in nur eine Drehrichtung erfolgt .According to the invention, a method is carried out in which the detergent web is unwound from a first supply roll and wound on a second supply roll in cycles, the detergent web being transported by an approximately constant length per work cycle, the detergent web per work cycle in each case between one on the cylinder or the roller employed working position and a parked rest position, and the respective further transport takes place only in the turning movement or only in the parking movement in only one direction of rotation.

Die erfindungsgemäße Lehre beruht auf dem Grundgedanken, dass der Radius einer Rolle, insbesondere einer Abfallrolle, erfasst wird, so dass die Spuleinrichtung zum Aufspulen der Abfallrolle dann nur jeweils soweit gedreht wird, dass die erforderliche Lauflänge der Reinigungsmittelbahn auf den Umfang der Abfallrolle aufgespult wird. Bei jedem Reinigungsarbeitsgang wird jeweils nur diese Lauflänge verbraucht und zum nächsten Arbeitsgang durch eine frische Länge ersetzt. Im Ergebnis bedeutet dies, dass die Drehbewegung der Spuleinrichtung bei jedem abschnittsweisen Vorschub der Reinigungsmittelbahn in Abhängigkeit des Radius der Abfallrolle verändert werden kann. Bei kleinem Radius der Abfallrolle muss die Spuleinrichtung um einen relativ großen Drehwinkel weitergefördert werden, um den erforderlichen Vorschub der Reinigungsmittelbahn zu gewährleisten. Bei großem Radius der Abfallrolle dagegen ist nur eine relativ kleine Drehbewegung der Spuleinrichtung zur Gewährleistung des entsprechenden Vorschubs der Reinigungsmittelbahn erforderlich.The teaching according to the invention is based on the basic idea that the radius of a roll, in particular a waste roll, is recorded, so that the winding device for winding up the waste roll is then only rotated to such an extent that the required length of the cleaning agent web is wound onto the circumference of the waste roll. In each cleaning operation, only this run length is used and replaced by a fresh length for the next operation. As a result, this means that the rotational movement of the winding device can be changed with each section-wise feed of the cleaning agent web depending on the radius of the waste roll. If the radius of the waste roll is small, the winding device must have a relatively large one Angle of rotation are conveyed further to ensure the necessary feed of the cleaning agent web. With a large radius of the waste roll, on the other hand, only a relatively small rotary movement of the winding device is required to ensure the corresponding advance of the detergent web.

Besonders vorteilhaft ist es dabei, wenn der Betrag der Drehbewegung der Spuleinrichtung beim abschnittsweisen Vorschub der Reinigungsmittelbahn derart verändert wird, dass die Länge des Vorschubabschnitts unabhängig vom Radius der Abfallrolle jeweils annähernd konstant bleibt. Durch diese Maßnahme wird gewährleistet, dass jeweils ein Vorschubabschnitt mit konstanter Länge weitergefördert wird, wobei die Länge des Vorschubabschnittes gerade so zu wählen ist, dass eine ausreichende Reinigungswirkung erzielt wird.It is particularly advantageous if the amount of the rotary movement of the winding device is changed during the section feed of the cleaning agent web in such a way that the length of the feed section remains approximately constant regardless of the radius of the waste roll. This measure ensures that in each case a feed section with a constant length is conveyed further, the length of the feed section being selected so that a sufficient cleaning effect is achieved.

Nach einer bevorzugten Ausführungsform der Erfindung wird die Reinigungsmittelbahn mittels einer andrückrakelartigen Andrückeinrichtung gegen den Umfang des Zylinders oder der Walze gedrückt. Durch diese Maßnahme wird die mit der Reinigungsmittelbahn erzielbare Reinigungswirkung stark erhöht und der Verbrauch vermindert .According to a preferred embodiment of the invention, the cleaning agent web is pressed against the circumference of the cylinder or the roller by means of a pressure-type doctor device. This measure greatly increases the cleaning effect that can be achieved with the cleaning agent web and reduces consumption.

Die Andrückeinrichtung soll dabei zwischen einer angestellten Arbeitsposition und einer abgestellten Ruheposition verstellbar sein. Durch diese Maßnahme kann erreicht werden, dass der Zylinder oder die Walze nicht permanent gereinigt wird, sondern eine Reinigung nur bei Verstellung der Andrückeinrichtung in die angestellte Arbeitsposition durchgeführt wird.The pressing device should be adjustable between an employed work position and a parked rest position. This measure ensures that the cylinder or the roller is not permanently cleaned, but is only cleaned when the pressing device is adjusted to the working position employed.

Um einen möglichst einfachen Aufbau der Reinigungsvorrichtung zu erreichen ist es besonders vorteilhaft, wenn mit der Antriebseinrichtung zur Verstellung der Andrückeinrichtung auch die Spuleinrichtung der Abfallrolle mittelbar oder unmittelbar drehbeweglich antreibbar ist. Im Ergebnis wird dadurch erreicht, dass mit nur einer Antriebseinrichtung, beispielsweise einem pneumatischen oder hydraulischen Stellzylinder, sowohl die Spuleinrichtung der Abfallrolle als auch die Andrückeinrichtung angetrieben wird.In order to achieve the simplest possible construction of the cleaning device, it is particularly advantageous if the drive device is used for adjustment the pressing device, the winding device of the waste roll can be driven indirectly or directly rotatably. As a result, both the winding device of the waste roll and the pressing device are driven with only one drive device, for example a pneumatic or hydraulic actuating cylinder.

Um einen intermittierenden Vorschub der Reinigungsmittelbahn zwischen den verschiedenen Reinigungszyklen gewährleisten zu können, kann zwischen der Antriebseinrichtung zum gleichzeitigen Antrieb der Spuleinrichtung und der Andrückeinrichtung und der Spuleinrichtung der Abfallrolle eine Freilaufeinrichtung vorgesehen sein. Durch diese Freilaufeinrichtung wird die Stellbewegung der Antriebseinrichtung nur in einer Richtung auf die Spuleinrichtung übertragen. In der anderen Richtung läuft der Freilauf frei, so dass die Spuleinrichtung in nur einem Drehsinn angetrieben wird.In order to be able to ensure an intermittent feed of the cleaning agent web between the different cleaning cycles, a freewheel device can be provided between the drive device for simultaneously driving the winding device and the pressing device and the winding device of the waste roll. With this freewheel device, the actuating movement of the drive device is transmitted to the winding device only in one direction. In the other direction, the freewheel runs freely, so that the winding device is driven in only one direction.

Besonders einfache Reinigungsvorrichtungen können durch Einsatz von mechanischen Hebelwerken realisiert werden. Zur Gewährleistung der Funktion ist es dabei erforderlich, dass die effektive Hebellänge des Hebelwerks in Abhängigkeit des Radius der Abfallrolle veränderbar ist. Dies bedeutet mit anderen Worten, dass die erforderliche Veränderung des Antriebsdrehwinkels durch Veränderung der effektiven Hebellänge des Hebelwerks gewährleistet wird.Particularly simple cleaning devices can be implemented using mechanical lever mechanisms. To ensure the function, it is necessary that the effective lever length of the lever mechanism can be changed depending on the radius of the waste roll. In other words, this means that the required change in the drive rotation angle is ensured by changing the effective lever length of the lever mechanism.

Die Verstellung der effektiven Hebellänge des Hebelwerkes kann beispielsweise durch einen Stellhebel übernommen werden, an dessen einem Ende eine Laufrolle drehbar gelagert ist, und wobei die Laufrolle am Umfang der Abfallrolle zur Anlage kommt. Durch Änderung des Radius der Abfallrolle wird dieser Stellhebel dann in seiner Position verändert, wobei durch die Änderung der Position des Stellhebels die effektive Hebellänge des Hebelwerks beeinflusst wird.The adjustment of the effective lever length of the lever mechanism can be carried out, for example, by an adjusting lever, at one end of which a roller is rotatably mounted, and the roller comes to rest on the circumference of the waste roller. By changing the radius of the waste roll, this position lever is then changed in its position, whereby by the Changing the position of the control lever affects the effective lever length of the lever mechanism.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im Folgenden näher beschrieben.An embodiment of the invention is shown in the drawings and is described in more detail below.

Die in Fig. 1 dargestellte Vorrichtung 01, z. B. eine Reinigungsvorrichtung 01, dient zur Reinigung einer in einem Farbwerk feststehend gelagerten Farbwalze 02. In der Vorrichtung 01 wird eine Reinigungsmittelbahn 03, beispielsweise eine Bahn aus Reinigungspapier oder einem Reinigungstuch, von einer Vorratsrolle 04 abgespult. Zum Vorschub der Reinigungsmittelbahn 03 wird eine Spuleinrichtung 06, beispielsweise eine Antriebsspindel 06, intermittierend drehend angetrieben, wobei sich dadurch auf der Spuleinrichtung 06 eine zweite Vorratsrolle 07, insbesondere eine Abfallrolle 07, bildet. Bei dem in Fig. 1 dargestellten Prozesszustand ist die Vorratsrolle 04 gerade neu gewechselt und die Abfallrolle 07 weist somit ihren minimalen Radius, der im Wesentlichen dem Radius der Spuleinrichtung 06 entspricht, auf .The device 01 shown in FIG. 1, e.g. B. a cleaning device 01 is used to clean a fixed in an inking roller 02. In the device 01, a cleaning agent web 03, for example a web of cleaning paper or a cleaning cloth, is unwound from a supply roll 04. To advance the cleaning agent web 03, a winding device 06, for example a drive spindle 06, is driven in an intermittently rotating manner, thereby forming a second supply roll 07, in particular a waste roll 07, on the winding device 06. In the illustrated in Fig. 1 Process state, the supply roll 04 has just been changed and the waste roll 07 thus has its minimum radius, which essentially corresponds to the radius of the winding device 06.

Um die Reinigungswirkung der Reinigungsmittelbahn 03 zu erhöhen, wird diese über eine Andrückeinrichtung 08, die in der Art eines Andrückrakels 08 ausgebildet ist, geführt. Die Andrückeinrichtung 08 ist fest mit einem Stellhebel 09 verbunden, der mittels einer Antriebseinrichtung 11, die in der Art eines pneumatischen AntriebsZylinders 11 ausgebildet ist, um eine Drehachse 12 verschwenkt werden kann. Durch Verschwenken des Stellhebels 09 kann die Andrückeinrichtung 08 an die Farbwalze 02 angestellt werden.In order to increase the cleaning effect of the cleaning agent web 03, it is guided over a pressure device 08, which is designed in the manner of a pressure doctor blade 08. The pressing device 08 is firmly connected to an adjusting lever 09, which can be pivoted about an axis of rotation 12 by means of a drive device 11, which is designed in the manner of a pneumatic drive cylinder 11. The pressing device 08 can be set against the inking roller 02 by pivoting the adjusting lever 09.

Die Antriebseinrichtung 11 wirkt über die Stellhebel 13, 14 und 16, die gemeinsam ein Hebelwerk bilden, auf die Spuleinrichtung 06. Dazu umfasst das eine Ende des Stellhebels 16 die Spuleinrichtung 06 mit einer Freilaufeinrichtung 15. Im Ergebnis wird dadurch erreicht, dass bei Ausfahren der Stellstange 17 der Antriebseinrichtung 11, die Andrückeinrichtung 08 an die Farbwalze 02 angestellt und die damit verbundene Drehbewegung des Stellhebels 16 auf die Spuleinrichtung 06 übertragen wird, so dass die Reinigungsmittelbahn 03 ein stückweit auf die Abfallrolle 07 aufgespult wird. Damit steht beim Anstellen der Reinigungsmittelbahn 03 an die Farbwalze 02 ein jeweils frischer Abschnitt der Reinigungsmittelbahn 03 zur Verfügung.The drive device 11 acts on the winding device 06 via the setting levers 13, 14 and 16, which together form a lever mechanism. For this purpose, one end of the setting lever 16 includes the winding device 06 with a freewheel device 15. As a result, when the Adjusting rod 17 of the drive device 11, the pressing device 08 is placed on the inking roller 02 and the associated rotary movement of the adjusting lever 16 is transmitted to the winding device 06, so that the cleaning agent web 03 is wound onto the waste roll 07 to a certain extent. A fresh section of the cleaning agent web 03 is thus available when the cleaning agent web 03 is placed against the inking roller 02.

Wird die Stellstange 17 anschließend wieder eingefahren und die Andrückeinrichtung 08 damit abgestellt, so läuft die Freilaufeinrichtung 15 frei, so dass die Drehbewegung des Stellhebels 16 entgegen dem Uhrzeigersinn nicht auf die Spuleinrichtung 06 übertragen wird. Um ein spielfreies Anliegen des Hebelwerkes aus den Stellhebeln 13, 14 und 16 jederzeit gewährleisten zu können, ist zwischen dem Stellhebel 09 und der Verbindungsachse zwischen den Stellhebeln 13 und 14 eine Federelement 18, insbesondere eine Spannfeder 18, vorgesehen.If the actuating rod 17 is then retracted again and the pressing device 08 is thus switched off, the freewheel device 15 runs free, so that the rotational movement of the actuating lever 16 in the counterclockwise direction is not transmitted to the winding device 06. A spring element 18, in particular a tension spring 18, is provided between the control lever 09 and the connecting axis between the control levers 13 and 14 in order to be able to ensure that the lever mechanism from the control levers 13, 14 and 16 can rest at any time without play.

Der Durchmesser der Abfallrolle 07 wird mit einer Laufrolle 19 erfasst, die am Ende eines Stellhebels 21 drehbar gelagert ist. Das andere Ende des Stellhebels 21 ist mit der Verbindungsachse zwischen den Stellhebeln 13 und 14 verbunden. Entsprechend dem Radius der Abfallrolle 07 wandert der Stellhebel 21 nach unten bzw. nach oben und verändert dadurch entsprechend die effektive Hebellänge des aus den Stellhebeln 13, 14 und 16 gebildeten Hebelwerks.The diameter of the waste roller 07 is detected with a roller 19 which is rotatably mounted at the end of an actuating lever 21. The other end of the control lever 21 is connected to the connecting axis between the control levers 13 and 14. In accordance with the radius of the waste roller 07, the adjusting lever 21 moves downward or upward, thereby changing the effective lever length of the lever mechanism formed from the adjusting levers 13, 14 and 16.

In Fig. 2 ist die Vorrichtung 01 im nachfolgenden Prozessschritt dargestellt, nachdem die Stellstange 17 ausgefahren wurde. Durch Verstellung des Stellhebels 16 im Uhrzeigersinn wurde die Reinigungsmittelbahn 03 ein stückweit auf die Abfallrolle 07 aufgespult und damit weitergefördert. Zugleich wurde die Andrückeinrichtung 08 durch Verschwenken des Stellhebels 09 in Uhrzeigersinn an die Farbwalze 02 angestellt. In Fig. 1 ist die Stellung des Stellhebels 16 im Prozesszustand gemäß Fig. 2 strichliniert angedeutet. Man erkennt, dass aufgrund der relativ großen effektiven Hebellänge des Hebelwerkes beim Ausfahren der Stellstange 17 der Stellhebel 16 um einen relativ großen Winkel verschwenkt wird. Die Vorschublänge beim Weiterfördern der Reinigungsmittelbahn 03, die sich aus dem Radius der Abfallrolle 07 und dem Schwenkwinkel des Stellhebels 16 ergibt, wird dadurch trotz des relativ geringen Radius der Abfallrolle 07 auf einem ausreichend hohen Maß erhalten.2, the device 01 is shown in the subsequent process step after the actuating rod 17 has been extended. By adjusting the adjusting lever 16 clockwise, the cleaning agent web 03 was wound a little way onto the waste roll 07 and thus conveyed further. At the same time, the pressing device 08 was turned against the inking roller 02 by pivoting the setting lever 09 clockwise. The position of the actuating lever 16 in the process state according to FIG. 2 is indicated by dashed lines in FIG. 1. It can be seen that, due to the relatively large effective lever length of the lever mechanism, the adjusting lever 16 is pivoted through a relatively large angle when the adjusting rod 17 is extended. The feed length when conveying the cleaning agent web 03, which results from the radius of the waste roller 07 and the pivoting angle of the actuating lever 16, is thereby maintained to a sufficiently high degree despite the relatively small radius of the waste roller 07.

In Fig. 3 ist die Vorrichtung 01 in einem Prozesszustand dargestellt, bei dem die Vorratsrolle 04 beinahe vollständig erschöpft ist und die Abfallrolle 07 einen entsprechend großen Radius aufweist. Zugleich ist die Stellstange 17 eingefahren und somit die Andrückeinrichtung 08 von der Farbwalze 02 abgestellt .3 shows the device 01 in a process state in which the supply roll 04 is almost complete is exhausted and the waste roll 07 has a correspondingly large radius. At the same time, the actuating rod 17 is retracted and thus the pressing device 08 is switched off by the inking roller 02.

Aufgrund des großen Radius der Abfallrolle 07 ist der Stellhebel 21 weit nach unten gedrückt, wodurch sich die effektive Hebellänge des Hebelwerks aus den Stellhebeln 13, 14 und 16 entsprechend verringert.Due to the large radius of the waste roller 07, the actuating lever 21 is pressed far down, as a result of which the effective lever length of the lever mechanism from the actuating levers 13, 14 and 16 is correspondingly reduced.

In Fig. 4 ist die Vorrichtung 01 in dem an den in Fig. 3 nachfolgenden Prozesszustand dargestellt, nachdem die Andrückeinrichtung 08 durch Ausfahren der Stellstange 17 an die Farbwalze 02 angestellt ist. Man erkennt, dass durch die Verringerung der effektiven Hebellänge des Hebelwerkes erreicht wird, dass bei vollem Ausfahren der Stellstange 17 der Stellhebel 16 nur um einen relativ kleinen Winkel im Uhrzeigersinn angetrieben wird. Somit ist gewährleistet, dass trotz des relativ großen Radius der Abfallrolle 07 die Reinigungsmittelbahn 03 nur um einen Längenabschnitt vorgeschoben wird, dessen Länge annähernd der Länge des Vorschubabschnittes entsprechend dem Vorschub zwischen den in Fig. 1 und Fig. 2 dargestellten Prozesszuständen entspricht. Das heißt, dass durch die Verstellung des Stellhebels 21 erreicht wird, dass trotz der konstanten Stellbewegung der Antriebseinrichtung 11 und trotz der Vergrößerung des Radius der Abfallrolle 07 die Vorschublänge im Wesentlichen konstant gehalten werden kann.4 shows the device 01 in the process state following that in FIG. 3, after the pressing device 08 is set against the inking roller 02 by extending the actuating rod 17. It can be seen that by reducing the effective lever length of the lever mechanism it is achieved that when the adjusting rod 17 is fully extended, the adjusting lever 16 is only driven clockwise by a relatively small angle. This ensures that, despite the relatively large radius of the waste roll 07, the cleaning agent web 03 is only advanced by a length section whose length approximately corresponds to the length of the feed section corresponding to the feed between the process states shown in FIGS. 1 and 2. This means that the adjustment of the actuating lever 21 ensures that, despite the constant actuating movement of the drive device 11 and despite the increase in the radius of the waste roller 07, the feed length can be kept essentially constant.

In Fig. 5 sind die verschiedenen Teile der Vorrichtung 01 im Querschnitt von oben dargestellt, wobei die verschiedenen Teile aufgrund der versetzten Zeichnungsdarstellung nicht dem relativen Längenmaßstab entsprechen. Bezugszeichenliste5 shows the different parts of the device 01 in cross section from above, the different parts not corresponding to the relative length scale due to the offset drawing.
