- Fig. 1 is a printing unit of a multi-color rotary printing machine shown schematically. It essentially consists of one Printing cylinder 1, a transfer drum 3 in the direction of sheet travel is upstream. In a manner known per se, the printing cylinder 1 a blanket cylinder 4 adjacent, which with a plate cylinder 5th is in contact. The plate cylinder 5 has a dampening system and an inking unit, which are not shown here.
- the blanket cylinder 4 and the pressure cylinder 1 is assigned a washing device 2.
- the washing device 2 extends over the respective Width of the cylinder 1, 4 and consists essentially of one Housing which has a washing roller, e.g. a wash brush rotatable records. In the housing are for the controlled supply of detergent and water spray devices arranged.
- the spray devices are connected in terms of circuitry to a controller.
- This Control is in turn circuitry with a time determination and a sheet counter coupled.
- the washing roller has one separate drive and is constantly engaged with a squeegee. At the lowest point of the housing is a drain for the fluid Detergent and water provided.
- the washing device 2 has for starting and stopping and lifting the device from one Cylinder channel or two on the frame side of a gripper bridge articulated working cylinders.
- Preferred detergents are biological detergents based on vegetable oil esters.
- 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.
- 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.
- the washing device 2 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 control system can also only query the time determiner at the beginning of a washing process for the purpose of controlling the detergent and water supply. 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.

Abstract
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 of a cylinder of a rotary printing press. The invention is particularly suitable for cleaning blanket cylinders, Impression cylinders as well as plate cylinders or forme cylinders, for example in a painting 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.DE-AS 1 150 098 discloses a washing device with a washing roller known that the cleaning of the outer surface of a printing cylinder serves. According to EP 0 004 605 A1, one is in one Washing device mounted on a pivot joint with a washing roller is known, a control curve in the area of the gripper of the printing cylinder having. This control curve is used to attach the pressure cylinder employed washing roller from the outer surface of the cylinder in one defined angle so that the washing roller does not match the Gripper collides.
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 in the uncontrolled Washing cycle is introduced. This leads to over-humidification of the Washing rollers with detergent or the washing roller is too dry at insufficient detergent supply. In case of over-humidification, a lot becomes unnecessarily Detergent consumed and the drying times of the cylinder surface are high or the cylinder jacket is not sufficient dry. This leads to different washing results that differ has a negative impact on the print quality of subsequent sheets.
Eine weitere Reinigungsvorrichtung für Zylinder einer Druckmaschine ist aus der DE 4301410A1 bekannt. Die Reinigungsvorrichtung weist eine auf den Zylinder gerichtete Sprühvorrichtung auf, die eine vorgeschaltete Speicherleitung besitzt. Die Speicherleitung besitzt Schaltventile, welche abhängig von Parametern und Betriebszuständen steuerbar sind.Another cleaning device for cylinders of a printing press is from DE 4301410A1 known. The cleaning device has one directed towards the cylinder Spray device that has an upstream storage line. The storage line has switching valves which can be controlled depending on parameters and operating states are.
Aus der WO 91/13760 ist ein Sprühfeuchtwerk für Zylinder einer Druckmaschine bekannt, welches auch mit Waschmittel betrieben werden kann. Die Ventile für die Waschmittelzufuhr werden von einer Steuereinheit geschaltet. Dazu wird die Anzahl der Zylinderumdrehungen erfaßt.A spray dampening unit for cylinders of a printing press is known from WO 91/13760, which can also be operated with detergent. The valves for the detergent supply are switched by a control unit. To do this, the number of cylinder revolutions detected.
Letztlich ist aus der EP 0654350 A1 ein Verfahren zum Reinigen von Zylindern einer Druckmaschine bekannt. Zur Ermittlung des optimalen Waschablaufprogrammes wird das zurückliegende Druckvolumen bzw. der Verschmutzungsgrad oder die Länge des Intervalls seit dem letzten Waschvorgang als Betriebsparameter berücksichtigt.Ultimately, EP 0654350 A1 describes a method for cleaning cylinders Printing machine known. To determine the optimal wash cycle program, this is past print volume or the degree of contamination or the length of the interval taken into account as an operating parameter since the last wash.
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 3.
Weiterbildungen ergeben sich aus den Unteransprüchen.The object of the invention is to provide a method and an arrangement
develop that always by a controlled detergent supply
approximately the same degree of moisture in a washing roller or
a washcloth at the start of the wash. This will be solved
by the characterizing part of
Mit der erfindungsgemäßen Lösung wird eine optimale Waschwirkung bei minimalem Waschmittel- und Wasserverbrauch erzielt. Zu Beginn eines Waschvorganges wird die Zeit und ggf. die Anzahl der bedruckten Bogen zum vorherigen Waschvorgang ermittelt. Abhängig von der vergangenen Zeit und ggf. 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 there is an optimal washing effect achieved with minimal detergent and water consumption. At the start the time and, if necessary, the number of prints Sheet determined for the previous washing process. Depending on the past time and, if applicable, the number of previously printed sheets the amount of detergent and / or water is controlled by a controller with which a uniform, predetermined level of moisture the washing roller or washcloth before starting achieved the cylinder surface in the pre-wetting phase becomes. When placing the washing roller / washcloth on the one to be cleaned Cylinder then each washing process with the same degree of moisture of washing roller or washcloth. This reduces the consumption of detergent and water. The previously known drying out of Wash roller / wash cloth due to different lengths of breaks between the washing processes in which evaporation occurs thereby eliminated. The control can be time-dependent and / or also depending on the number of sheets printed, the length of the washing process establish. So after setting up the press or if the number of runs is small, the washing time is shorter chosen. Subsequent to high circulation numbers becomes a temporal longer washing process selected.
Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden. Dabei zeigt
- Fig. 1
- ein Druckwerk einer Rotationsdruckmaschine gekoppelt mit einer Steuerung.
- 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 is a printing unit of a multi-color rotary printing machine
shown schematically. It essentially consists of one
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
den
Zeitermittler zu Beginn eines Waschvorganges zwecks Steuerung der
Waschmittel- und Wasserzuführung abfragen.
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:
