Durch die Erfindung soll die Aufgabe gelöst werden, eine bessere Reinigung des Zylinders zu erzielen, insbesondere eine zusätzliche Verschmutzung der Greifer und von im Zylinder gebildeten Gruben beim Reinigungsvorgang zu vermeiden.The object of the invention is to achieve a better cleaning to achieve the cylinder, especially additional pollution of the Grippers and pits formed in the cylinder during the cleaning process avoid.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß eine Steuereinrichtung vorgesehen ist, welche in Abhängigkeit von vorbestimmten Drehwinkelpositionen des Zylinders während eines Reinigungsbetriebes das Anlegen und Abstellen des Andrückelementes an die Zylinder-Umfangsfläche derart steuert, daß während einer ersten Reinigungsphase des Reinigungsbetriebes bei jeder Zylinderumdrehung das Andrückelement an die Zylinder-Umfangsfläche angestellt ist, solange ein vorbestimmter zu reinigender erster Zylinderumfangsabschnitt an ihm vorbeiläuft, jedoch das Andrückelement von der Zylinder-Umfangsfläche abgestellt ist, solange ein vorgestimmter zweiter Zylinderumfangsabschnitt an ihm vorbeiläuft, daß während einer zweiten Reinigungsphase des Reinigungsbetriebes bei jeder Zylinderumdrehung das Andrückelement an dieZylinder-Umfangsfläche angestellt ist, solange der vorbestimmte zu reinigende zweite Zylinderumfangsabschnitt an ihm vorbeiläuft, jedoch das Andrückelement von der Zylinder-Umfangsfläche abgestellt ist, solange der vorbestimmte erste Zylinderumfangsabschnitt an ihm vorbeiläuft, daß jeder der Umfangsabschnitte des Zylinders an einer der Greiferanordnungen beginnt und vor einer anderen der Greiferanordnungen endet. This object is achieved according to the invention in that a Control device is provided, which is dependent on predetermined Angle of rotation positions of the cylinder during a cleaning operation Applying and setting down the pressure element on the circumferential surface of the cylinder controls such that during a first cleaning phase of the Cleaning operation with each cylinder revolution, the pressure element on the Cylinder peripheral surface is employed as long as a predetermined one cleaning first cylinder circumferential section passes him, but that Pressure element is turned off from the cylinder circumferential surface as long as predetermined second cylinder circumferential section passes him that during a second cleaning phase of the cleaning company for everyone Cylinder rotation the pressing element on the cylinder peripheral surface is employed as long as the predetermined second to be cleaned Cylinder circumferential section passes him, but the pressing element of the cylinder peripheral surface is turned off as long as the predetermined first Cylinder circumferential section passes by it that each of the circumferential sections of the cylinder begins at one of the gripper assemblies and before another the gripper assemblies ends.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß die Steuereinrichtung derart ausgebildet ist, daß sie das Andrückelement zusammen mit dem ihn kontaktierenden Reinigungstuchabschnitt bereits innerhalb des Bereiches der Greiferanordnung von der abgestellten Position in die angestellte Position bewegt.According to a preferred embodiment of the invention it is provided that the control device is designed such that it the pressing element already together with the cleaning cloth section contacting him within the area of the gripper arrangement from the parked position in the position moved.

Gemäß einer anderen bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß die Steuereinrichtung derart ausgebildet ist, daß sie das Andrückelement zusammen mit dem ihn kontaktierenden Reinigungsttuchabschnitt bereits kurz zuvor, bevor die Greiferanordnung des zu reinigenden Zylinderumfangsabschnittes das Andrückelement erreicht, von der abgestellten Position in die angestellte Position bewegt.According to another preferred embodiment of the invention provided that the control device is designed such that it Pressing element together with the contacting him Cleaning cloth section just before, before the gripper assembly of the reaches the pressure element to be cleaned, from moved from the parked position to the employed position.

Vorteile der Erfindung:
Das verschmutzte Reinigungstuch kann seinen Schmutz nicht mehr an den Greifern oder den Kanten der Gruben abstreifen, in welchen die Greifer schwenkbar gelagert sind. Dadurch werden die Greifer von dem Reinigungstuch nur gereinigt, jedoch nicht mehr mit Schmutz eines den Greifern vorangehenden Zylinderumfangsabschnittes verschmutzt. Auch wird vermieden, daß das Reinigungstuch Schmutz in die Gruben hineinfördert. Dies hat eine gleichbleibend gute Funktion der Greifer zur Folge, welche zum Festhalten und Freigeben von Papierbögen jeweils Schwenkbewegungen ausführen. Durch die Reduzierung einer Verschmutzung der Greifer haben diese auch eine längere Lebensdauer. Das gleiche trifft für Stifte zu, welche unter den Greifern angeordnet sind und von welchen die Greifern wegschwenkbar sind, damit die Stifte das betreffende Ende eines Papierbogens vom Zylinder wegdrücken können, damit das Papierbogenende auf einen Abscherkamm auflaufen und dadurch vom Zylinder abgeführt werden kann.
Advantages of the invention:
The dirty cleaning cloth can no longer wipe off its dirt on the grippers or the edges of the pits in which the grippers are pivotally mounted. As a result, the grippers are only cleaned from the cleaning cloth, but are no longer contaminated with dirt from a cylinder circumferential section preceding the grippers. It is also avoided that the cleaning cloth carries dirt into the pits. This results in a consistently good function of the grippers, which each perform swiveling movements to hold and release sheets of paper. By reducing contamination of the grippers, they also have a longer service life. The same applies to pins which are arranged under the grippers and from which the grippers can be pivoted away, so that the pins can push the relevant end of a sheet of paper away from the cylinder, so that the end of the paper sheet runs onto a shearing comb and can thus be removed from the cylinder.

According to others However, embodiments can also only have one arrangement or three or more arrangements of grippers 12 and associated pits 14 are provided be for a corresponding number of printed sheets 6.

Die Druckbögen 6 sind in Fig.1 nur strichpunktiert schematisch dargestellt, weil die Erfindung eine Reinigungsvorrichtung und ein Reinigungsverfahren zum Reinigen der Umfangsfläche des Gegendruckzylinders 10 betrifft, wobei während des Reinigungsbetriebes keine Druckbögen 6 auf dem Gegendruckzylinder 10 angeordnet sind.The printed sheets 6 are only shown schematically in FIG. 1 because the invention a cleaning device and a cleaning method for Clean the peripheral surface of the impression cylinder 10, wherein during the cleaning operation no sheets 6 on the Impression cylinder 10 are arranged.

Die Reinigungsvorrichtung enthält ein Andrückelement 20, durch welches während eines Reinigungsbetriebes ein sich über dieses Andrückelement erstreckender Tuchabschnitt 22 eines Reinigungstuches 24 wechselweise an die Umfangsfläche des Gegendruckzylinders 10 anstellbar und wieder abstellbar ist. Das Reinigungstuch 24 kontaktiert in der angestellten Position die Umfangsfläche des Gegendruckzylinders 10, wobei es unbeweglich positioniert ist während es in der abgestellten Position die Umfangsfläche des Gegendruckzylinders 10 nicht kontaktiert und um einen vorbestimmten Tuchabschnitt 22 von einer Saubertuchrolle 26 auf eine Schmutztuchrolle 28 weitertransportiert wird.The cleaning device contains a pressure element 20, through which during a cleaning operation, this pressing element extending cloth section 22 of a cleaning cloth 24 alternately the peripheral surface of the impression cylinder 10 adjustable and again can be switched off. The cleaning cloth 24 contacts in the employed position the peripheral surface of the impression cylinder 10, being immobile is positioned while in the parked position the peripheral surface of the Back pressure cylinder 10 is not contacted and a predetermined Cloth section 22 from a clean cloth roll 26 to a dirty cloth roll 28 is transported further.

Zur Steuerung des Anstellens und Abstellens des Andrückelements 20 mit dem ihn umschlingenden Tuchabschsnitt 22 an die Umfangsfläche des Gegendruckzylinders 10 ist eine Steuereinrichtung 30 vorgesehen. Die Steuereinrichtung 30 ist vorzugsweise eine elektronische Einrichtung mit mindestens einem Datenprozessor und mit Steuerungsprogrammen, welche fest sein können oder von welchen mindestens einige vorzugsweise frei programmierbar sind. To control the starting and stopping of the pressing element 20 with the him wrapping cloth section 22 to the peripheral surface of the Back pressure cylinder 10, a control device 30 is provided. The Control device 30 is preferably an electronic device with at least one data processor and with control programs which can be solid or at least some of which are preferably free are programmable.

Die Steuereinrichtung 30 ist gemäß der Erfindung derart ausgebildet, daß sie in Abhängigkeit von vorbestimmten Drehwinkelpositionen des Gegendruckzylinders 10 und in Abhängigkeit von der Anzahl von Umdrehungen dieses Gegendruckzylinders 10 das Anstellen und Abstellen des Andrückelementes 20 steuert oder regelt.The control device 30 is designed according to the invention such that it depending on predetermined rotational angle positions of the Impression cylinder 10 and depending on the number of Revolutions of this impression cylinder 10 starting and stopping the Pressure element 20 controls or regulates.

Die Steuereinrichtung 30 bewirkt, daß während einer ersten Reinigungsphase eines Reinigungsbetriebes bei jeder Zylinderumdrehung das Andrückelement 20 an die Umfangsfläche des Gegendruckzylinders 10 nur angestellt ist, solange ein vorbestimmter zu reinigender erster Zylinderumfangsabschnitt 10A an ihm vorbeiläuft, jedoch das Andrückelement 20 von der Umfangsfläche abgestellt ist, solange ein vorbestimmter zweiter Zylinderumfangsabschnitt 10B an ihm vorbeiläuft.The control device 30 causes that during a first cleaning phase of a cleaning company the pressing element with each cylinder revolution 20 is only employed on the peripheral surface of the impression cylinder 10, as long as a predetermined first cylinder peripheral portion 10A to be cleaned runs past it, but the pressing element 20 from the peripheral surface is turned off as long as a predetermined second cylinder peripheral portion 10B past him.

Nach mindestens einer, vorzugsweise mehreren vollständigen Umdrehungen des Gegendruckzylinders 10 erfolgt durch die Steuereinrichtung 30 eine Umschaltung, durch welche das Andrückelement 20 um den Umfangsabstand zwischen den beiden aufeinander folgenden Anordnungen von Greifern 12 versetzt an den Gegendruckzylinder 10 angestellt und abgestellt wird. Dadurch ist während einer jetzt folgenden zweiten Reinigungsphase des Reinigungsbetriebes bei jeder Zylinderumdrehung das Andrückelement 20 an die Umfangsfläche des Gegendruckzylinders 10 angestellt, solange der vorbestimmte zu reinigende zweite Zylinderumfangsabschnitt 10B an ihm vorbeiläuft, jedoch das Andrückelement 20 von der Umfangsfläche des Gegendruckzylinders 10 abgestellt, solange der vorbestimmte erste Zylinderumfangsabschnitt 10A an ihm vorbeiläuft.After at least one, preferably several complete revolutions of the impression cylinder 10 is carried out by the control device 30 Switching through which the pressing element 20 by the circumferential distance between the two successive arrangements of grippers 12 is offset and turned on the impression cylinder 10. Thereby is during a second cleaning phase of the Cleaning operation with each cylinder revolution, the pressure element 20 the peripheral surface of the impression cylinder 10 turned on as long as predetermined second cylinder peripheral portion 10B to be cleaned thereon passes, but the pressing element 20 from the peripheral surface of the Back pressure cylinder 10 turned off as long as the predetermined first Cylinder peripheral portion 10A runs past it.

Jeder der Umfangsabschnitte 10A und 10B des Gegendruckzylinders 10 beginnt an einer der Anordnungen von Greifern 12 und endet an der folgenden Anordnung von Greifern 12. Bei der in Fig.1 gezeigten Ausführungsform sind zwei solche Anordnungen von je mehreren Greifern 12 diametral einander gegenüberliegend am Zylinderaußenumfang angeordnet.Each of the peripheral portions 10A and 10B of the impression cylinder 10 begins at one of the arrays of grippers 12 and ends at the following Arrangement of grippers 12. In the embodiment shown in Fig.1 are two such arrangements of several grippers 12 diametrically opposite each other arranged opposite to the outer circumference of the cylinder.

Die Steuereinrichtung 30 ist ferner derart ausgebildet, daß sie einen Weitertransport oder Vorschub des Reinigungstuches 24 um einen vorbestimmten Tuchabschsnitt 22 jeweils nur während der Zeit bewirkt, während welcher das Andrückelement 20 von dem betreffenden Zylinderumfangsabschnitt, 10A oder 10B abgestellt ist.The control device 30 is also designed such that it has a Further transport or advance of the cleaning cloth 24 by one predetermined tissue section 22 is effected only during the time which the pressing element 20 of the concerned Cylinder peripheral portion, 10A or 10B is turned off.

Somit wird während mindestens einer, vorzugsweise mehreren vollständigen Umdrehungen des Gegendruckzylinders 10 ein Tuchabschnitt 22 von dem Andrückelement 20 jeweils nur an den Zylinderumfangsabschnitt 10A und dessen Greifer 12 angelegt, jedoch nicht an den anderen Zylinderumfangsabschnitt 10B und dessen Greifer 12. Jedesmal, wenn dieser andere Zylinderumfangsabschnitt 10B am Gegendruckelement 20 vorbeiläuft, wird das Reinigungstuch 24 um einen Tuchabschnitt 22 weitertransportiert. Dann schaltet die Steuereinrichtung 30 in der genannten Weise um, so daß dann bei jeder Zylinderumdrehung das Andrückelement 20 mit dem Tuchabschnitt 22 an den Zylinderumfangsabschnitt 10B angestellt ist, jedoch vom anderen Zylinderumfangsabschnitt 10A abgestellt ist, so daß in dem anderen Zylinderumfangsabschnitt 10A bei jeder Zylinderumdrehung ein Weitertransport des Reinigungstuches 24 um die Länge eines Tuchabschnittes 22 erfolgt.Thus, at least one, preferably several, is complete Revolutions of the impression cylinder 10 a cloth section 22 of the Pressure element 20 only on the cylinder peripheral portion 10A and the gripper 12 applied, but not on the other Cylinder circumferential section 10B and its gripper 12. Every time this another cylinder circumferential section 10B passes the counter pressure element 20, the cleaning cloth 24 is transported further by a cloth section 22.
