Abstract

The cleaning system uses a washing roller (2) or a washing cloth, brought into contact with the surface of the cylinder to be cleaned. At the beginning of each new cleaning cycle the time interval since the last cleaning cycle and the counted number of printed sheets are used to determine the quantity of supplied cleaning fluid and the number of cleaning cycles. Pref. the next cleaning of the cylinder is initiated in dependence on the number of printed sheets and the amount of cleaning fluid is determined independence on the elapsed time from the last cleaning cycle.

Description

Die Erfindung betrifft ein Verfahren und eine Anordnung zur Reinigung eines Zylinder einer Rotationsdruckmaschine. Die Erfindung eignet sich insbesondere zur Reinigung von Gummituchzylindern, Gegendruckzylindern sowie von Plattenzylindern oder Formzylindern, beispielsweise in einer Lackiereinheit.The invention relates to a method and an arrangement for cleaning a cylinder of a rotary printing press. The invention is particularly suitable for cleaning blanket cylinders, impression cylinders and plate cylinders or forme cylinders, for example in a coating unit.

Aus der DE-AS 1 150 098 ist eine Waschvorrichtung mit einer Waschwalze bekannt, die der Reinigung der Mantelfläche eines Druckzylinders dient. Gemäß der EP 0 004 605 A1 ist eine in einem Drehgelenk gelagerte Waschvorrichtung mit einer Waschwalze bekannt, die im Bereich der Greifer des Druckzylinders eine Steuerkurve aufweist. Über diese Steuerkurve wird die an den Druckzylinder angestellte Waschwalze von der Mantelfläche des Zylinders in einem definierten Winkel abgehoben, damit die Waschwalze nicht mit den Greifer kollidiert.From DE-AS 1 150 098 a washing device with a washing roller is known, which is used to clean the outer surface of a printing cylinder. According to EP 0 004 605 A1, a washing device with a washing roller mounted in a swivel joint is known, which has a control cam in the area of the grippers of the printing cylinder. The wash roller attached to the pressure cylinder is lifted from the lateral surface of the cylinder at a defined angle via this control curve, so that the wash roller does not collide with the gripper.

Nachteilig ist es, daß die Waschmittelmenge unkontrolliert in den Waschzyklus eingebracht wird. Dies führt zur Überfeuchtung der Waschwalzen mit Waschmittel oder die Waschwalze Ist zu trocken bei zu geringer Waschmittelzufuhr. Bei Überfeuchtung wird unnötig viel Waschmittel verbraucht und die Trockenzeiten der Zylindermantelfläche sind hoch oder aber der Zylindermantel ist nicht ausreichend trocken. Dies führt zu unterschiedlichen Waschergebnissen, die sich negativ auf die Druckqualität nachfolgender Bogen auswirkt.It is disadvantageous that the amount of detergent is introduced into the washing cycle in an uncontrolled manner. This leads to overwetting of the washing rollers with detergent or the washing roller is too dry with insufficient detergent supply. In the event of over-humidification, an unnecessarily large amount of detergent is used and the drying times of the cylinder jacket surface are high or the cylinder jacket is not sufficiently dry. This leads to different washing results, which has a negative impact on the print quality of subsequent sheets.

Aufgabe der Erfindung ist es, ein Verfahren und eine Anordnung zu entwickeln, die durch eine gesteuerte Waschmittelzufuhr stets einen annähernd gleichen Feuchtigkeitsgrad bei einer Waschwalze oder einem Waschtuch zu Waschbeginn gewährleistet. Gelöst wird dies durch den kennzeichnenden Teil der Patentansprüche 1 und 4. Weiterbildungen ergeben sich aus den Unteransprüchen.The object of the invention is to develop a method and an arrangement which always have a controlled detergent supply approximately the same degree of moisture is guaranteed with a washing roller or a washcloth at the start of the wash. This is solved by the characterizing part of claims 1 and 4. Further developments result from the subclaims.

Mit der erfindungsgemäßen Lösung wird eine optimale Waschwirkung bei minimalem Waschmittel- und Wasserverbrauch erzielt. Zu Beginn eines Waschvorganges wird die Zeit und/oder die Anzahl der bedruckten Bogen zum vorherigen Waschvorgang ermittelt. Abhängig von der vergangenen Zeit bzw. der Anzahl der vorher bedruckten Bogen wird von einer Steuerung die Menge an Waschmittel und/oder Wasser bestimmt, mit der ein einheitlicher, vorherbestimmter Feuchtigkeitsgrad der Waschwalze oder des Waschtuches vor dem Anstellen an die Zylindermantelfläche in der Phase des Vorfeuchtens erzielt wird. Beim Anstellen von Waschwalze/Waschtuch an den zu reinigenden Zylinder erfolgt dann jeder Waschvorgang mit dem gleichen Feuchtigkeitsgrad von Waschwalze bzw. Waschtuch. Dies reduziert den Waschmittel- und Wasserverbrauch. Das bisher bekannte Austrocknen der Waschwalze/Waschtuch aufgrund unterschiedlich langer Pausen zwischen den Waschvorgängen, in denen Verdunstung eintritt, ist dadurch beseitigt. Die Steuerung kann zeitabhängig und/oder auch abhängig von der Anzahl bedruckten Bogen die Länge des Waschvorganges festlegen. So wird nach Einrichten der Druckmaschine oder bei geringer Auflagenanzahl ein zeitlich kürzerer Waschvorgang gewählt. Anschließend an hohe Auflagenzahlen wird ein zeitlich längerer Waschvorgang gewählt.With the solution according to the invention, an optimal washing effect is achieved with minimal detergent and water consumption. At the beginning of a washing process, the time and / or the number of printed sheets for the previous washing process is determined. Depending on the elapsed time or the number of previously printed sheets, a control determines the amount of detergent and / or water with which a uniform, predetermined degree of moisture of the washing roller or the wash cloth before it comes into contact with the cylinder surface in the pre-moistening phase is achieved. When the washing roller / washcloth is placed against the cylinder to be cleaned, each washing process is then carried out with the same degree of moisture from the washing roller or washcloth. This reduces the consumption of detergent and water. The previously known drying out of the washing roller / washing cloth due to differently long pauses between the washing processes in which evaporation occurs is thereby eliminated. The controller can determine the length of the washing process depending on the time and / or also on the number of printed sheets. For example, after setting up the press or with a small number of runs, a shorter washing process is selected. Following a high number of runs, a longer washing process is selected.

Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden. Dabei zeigt

ein Druckwerk einer Rotationsdruckmaschine gekoppelt mit einer Steuerung.
The invention will be explained in more detail using an exemplary embodiment. It shows
Fig. 1
a printing unit of a rotary printing press coupled with a controller.

In Fig. 1 ist ein Druckwerk einer Mehrfarben-Rotationsdruckmaschine schematisch dargestellt. Es besteht im Wesentlichen aus einem Druckzylinder 1, dem in Bogenlaufrichtung eine Transfertrommel 3 vorgeordnet ist. In an sich bekannter Weise ist dem Druckzylinder 1 ein Gummituchzylinder 4 benachbart, der mit einem Plattenzylinder 5 in Kontakt steht. Der Plattenzylinder 5 besitzt ein Feuchtwerk und ein Farbwerk, welche hier nicht gezeigt sind. Dem Gummituchzylinder 4 und dem Druckzylinder 1 ist je eine Waschvorrichtung 2 zugeordnet. Die Waschvorrichtung 2 erstreckt sich über die jeweilige Breite der Zylinder 1, 4 und besteht im Wesentlichen aus einem Gehäuse, welches eine Waschwalze, z.B. eine Waschbürste drehbar aufnimmt. Im Gehäuse sind zur gesteuerten Zufuhr von Waschmittel und Wasser Sprüheinrichtungen angeordnet. Die Sprüheinrichtungen sind schaltungstechnisch mit einer Steuerung gekoppelt. Diese Steuerung ist wiederum schaltungstechnisch mit einer Zeitermittlung und einem Bogenzähler gekoppelt. Die Waschwalze besitzt einen separaten Antrieb und steht mit einem Rakel ständig im Eingriff. Am tiefsten Punkt des Gehäuses ist ein Ablauf für das Fluid aus Waschmittel und Wasser vorgesehen. Die Waschvorrichtung 2 besitzt zum An- und Abstellen sowie zum Abheben der Vorrichtung von einem Zylinderkanal bzw. von einer Greiferbrücke zwei gestellseitig angelenkte Arbeitszylinder. Als Waschmittel werden vorzugsweise biologische Waschmittel auf Basis von Pflanzenölestern eingesetzt.In Fig. 1, a printing unit of a multi-color rotary printing press is shown schematically. It essentially consists of a printing cylinder 1, which has a transfer drum 3 in the direction of sheet travel is upstream. In a manner known per se, the printing cylinder 1 is adjacent to a blanket cylinder 4 which is in contact with a plate cylinder 5. The plate cylinder 5 has a dampening unit and an inking unit, which are not shown here. A washing device 2 is assigned to the blanket cylinder 4 and the impression cylinder 1. The washing device 2 extends over the respective width of the cylinders 1, 4 and essentially consists of a housing which rotatably accommodates a washing roller, for example a washing brush. Spray devices are arranged in the housing for the controlled supply of detergent and water. In terms of circuitry, the spray devices are coupled to a controller. In terms of circuitry, this control is in turn coupled to a time determination and a sheet counter. The washing roller has a separate drive and is constantly engaged with a squeegee. At the lowest point of the housing there is a drain for the fluid from the detergent and water. The washing device 2 has two working cylinders articulated on the frame side for starting and stopping and lifting the device from a cylinder channel or from a gripper bridge. Organic detergents based on vegetable oil esters are preferably used as detergents.

Die Wirkungsweise ist wie folgt:
Normalerweise befindet sich jede Waschvorrichtung 2 in abgestellter Position. Es wird lediglich eine Vorrichtung 2 am Gummituchzylinder 4 betrachtet. Die Arbeitsweise der Vorrichtung 2 am Druckzylinder ist dazu analog. Zu Beginn eines Waschvorganges wird von der elektronischen Steuerung der Zeitermittler und der Bogenzähler abgefragt. Der Zeitermittler gibt die Zeit vom vorangegangenen Waschvorgang an. Der Bogenzähler gibt die Anzahl der seit dem vorangegangenen Waschvorgang bedruckten Bogen an. Beide Werte werden von der Steuerung verarbeitet und dementsprechend wird die erforderliche Menge an Waschmittel und Wasser zum Vorfeuchten der Waschvorrichtung 2 zugeführt. Über das Kriterium der Zeit läßt sich der Grad der Verdunstung von Waschmittel und Wasser aus der Waschvorrichtung 2 beurteilen und somit auch der Feuchtigkeitsgrad der Waschwalze. Ist die zeitliche Differenz zwischen letztem Waschvorgang und dem beginnenden Waschvorgang relativ groß, so wird die Waschvorrichtung 2, hier die Waschwalze, mit mehr Waschmittel und Wasser vorgefeuchtet. Ist die zeitliche Differenz zwischen letztem Waschvorgang und dem beginnenden Waschvorgang kleiner, so wird die Waschvorrichtung 2, hier die Waschwalze, mit weniger Waschmittel und Wasser vorgefeuchtet. Über das Kriterium der Bogenanzahl läßt sich der Grad der Verschmutzung des jeweils zu reinigen Zylinders, hier des Gummituchzylinders 4, beurteilen. Ist die Anzahl an bedruckten Bogen hoch, so wird der Ablauf des festgelegten Waschvorganges mehrfach wiederholt. Ist die Anzahl an bedruckten Bogen gering, z.B. beim Einrichten, so wird ein zeitlich kürzerer Waschvorgang durchgeführt. Die Steuerung kann auch nur nach einem der Kriterien arbeiten. So ist es möglich, nur den Zeitermittler zu Beginn eines Waschvorganges zwecks Steuerung der Waschmittel- und Wasserzuführung abzufragen. Andererseits kann die Anzahl der Waschvorgänge bei Abfragen des Bogenzählers für die Waschmittel- und Wasserzuführung ausreichend sein. Jeder Waschvorgang beginnt somit stets mit einem gleichen Feuchtigkeitsgehalt der Waschwalze bei Abfrage des Zeitermittlers. Der Waschmittel- und Wasserverbrauch kann damit reduziert werden und die Gefahr des trockenen Anlaufens der Waschvorrichtung bei Anstellung an einen Gummituchzylinder 4 wird vermieden.The mode of action is as follows:
Each washing device 2 is normally in the parked position. Only a device 2 on the blanket cylinder 4 is considered. The operation of the device 2 on the impression cylinder is analogous to this. At the beginning of a washing process, the electronic control interrogates the time determiner and the sheet counter. The time determiner indicates the time from the previous washing process. The sheet counter indicates the number of sheets printed since the previous washing process. Both values are processed by the control and, accordingly, the amount of detergent and water required to pre-wet the washing device 2 is supplied. The degree of evaporation of detergent and water from the washing device 2 and thus also the degree of moisture of the washing roller can be assessed using the criterion of time. Is the time difference between the last one Washing process and the beginning of the washing process relatively large, the washing device 2, here the washing roller, is pre-moistened with more detergent and water. If the time difference between the last washing process and the beginning washing process is smaller, the washing device 2, here the washing roller, is pre-moistened with less detergent and water. The degree of soiling of the cylinder to be cleaned, here of the blanket cylinder 4, can be assessed via the criterion of the number of sheets. If the number of printed sheets is high, the sequence of the specified washing process is repeated several times. If the number of printed sheets is small, for example when setting up, a shorter washing process is carried out. The controller can only work according to one of the criteria. So it is possible to query only the time attendant at the beginning of a washing process in order to control the detergent and water supply. On the other hand, the number of washing processes when querying the sheet counter for the detergent and water supply can be sufficient. Each washing process therefore always begins with the same moisture content in the washing roller when the time-keeping device is queried. The detergent and water consumption can thus be reduced and the risk of the washing device starting dry when it is placed against a blanket cylinder 4 is avoided.
