Description

Die Erfindung betrifft eine Vorrichtung zum Reinigen der Mantelfläche eines Zylinders einer Druckmaschine mit einem eine dem Zylinder zugekehrte Öffnung aufweisenden Gehäuse zur Aufnahme eines mit dem Zylinder in Kontakt bringbaren, drehbeweglichen Reinigungselements, einer Zuführung für ein Reinigungsfluid und einer Zuführung für Wasser und mit einem Ablauf zur Abführung von verschmutztem Reinigungsfluid.The invention relates to a device for cleaning the lateral surface of a cylinder of a printing press with a cylinder-facing opening having a housing for receiving a cylinder in contact, rotatable cleaning element, a supply for a cleaning fluid and a supply of water and a drain for Removal of contaminated cleaning fluid.

Bei einer aus DE 296 12 400 U1 bekannten Reinigungsvorrichtung der angegebenen Art bestehen die Zuführungen für Reinigungsfluid und Wasser aus zwei in dem Gehäuse angeordneten Sprührohren, die sich über die Breite der Reinigungsvorrichtung erstrecken und mehrere über die Länge in Abständen verteilt angeordnete Öffnungen haben, die auf das Reinigungselement gerichtet sind. Die Sprührohre sind mit einer Zuführleitung gekoppelt, über die mit Hilfe eines Druckmittels das Reinigungsfluid bzw. Wasser zugeführt wird. Die Reinigungsvorrichtung weist eine in dem Gehäuse drehbar gelagerte Waschwalze auf, deren Welle mit einem eigenen Antrieb gekoppelt ist. Mit der Waschwalze ist eine Rakel ständig im Eingriff, die an dem Gehäuse befestigt ist.In one known from DE 296 12 400 U1 cleaning device of the specified type, the feeds for cleaning fluid and water from two arranged in the housing spray tubes that extend across the width of the cleaning device and have a plurality of spaced over the length spaced openings arranged on the cleaning element are directed. The spray pipes are coupled to a supply line, via which the cleaning fluid or water is supplied by means of a pressure medium. The cleaning device has a washing roller rotatably mounted in the housing, the shaft of which is coupled to its own drive. With the washing roller, a doctor blade is constantly engaged, which is fixed to the housing.

Es ist weiterhin aus DE 298 19 374 U1 eine Reinigungsvorrichtung zum Reinigen der Mantelfläche eines Zylinders in einer Druckmaschine bekannt, bei der in einem Gehäuse mit einer darin drehbar gelagerten Waschwalze zwei vorzugsweise durch Sprührohre gebildete Zuführsysteme zur Zuführung eines Reinigungsfluids angeordnet sind. Zumindest ein Zuführsystem ist hierbei drehbar am Gehäuse gelagert und mit einer Betätigungsvorrichtung gekoppelt, durch die das Zuführsystem in verschiedene Stellungen drehbar ist. Durch Drehen des Zuführsystems kann das aus Öffnungen austretende Reinigungsfluid auf die Waschwalze gerichtet oder von der Waschwalze abgewendet werden. Weiterhin kann hierbei ein Zuführsystem mit der Oberfläche der Waschwalze in Kontakt sein, um als Abstreifelement zu dienen.It is also known from DE 298 19 374 U1 a cleaning device for cleaning the lateral surface of a cylinder in a printing machine, in which are arranged in a housing with a rotatably mounted therein washing roller two preferably formed by spray pipes feeding systems for supplying a cleaning fluid. At least one feed system is in this case rotatably mounted on the housing and coupled to an actuating device, by means of which the feed system can be rotated into different positions. By rotating the delivery system, the cleaning fluid emerging from openings can be directed onto the washing roller or turned away from the washing roller. Furthermore, in this case, a feed system may be in contact with the surface of the washing roller to serve as a stripping element.

Das in Reinigungsvorrichtungen der angegebenen Art eingesetzte Reinigungsfluid hat die Aufgabe, Farbreste und Schmutz zu lösen, die auf der Oberfläche des zu reinigenden Zylinders haften. Das Reinigungsfluid ist daher in seiner Zusammensetzung auf das jeweils zum Drucken verwendete Farbsystem abgestimmt. So wird beispielsweise für herkömmliche Offset-Farbsysteme ein anderes Reinigungsfluid benötigt, als für die modernen UV-vernetzenden Farbsysteme oder für Lacke. Die unterschiedlichen. Reinigungsfluids sind vielfach miteinander unverträglich und dürfen daher nicht miteinander vermischt werden. Für den Druckbetrieb folgt hieraus, daß bei einem Wechsel des Farbsystems auch das der Reinigungsvorrichtung zugeführte Reinigungsfluid gewechselt werden muß, was mit einem zusätzlichen Umrüstaufwand und dem Verlust des Waschmittelinhalts der Zuführleitungen verbunden ist.The cleaning fluid used in cleaning devices of the specified type has the task of dissolving paint residues and dirt adhering to the surface of the cylinder to be cleaned. The cleaning fluid is therefore matched in its composition to the color system used in each case for printing. For example, a different cleaning fluid is required for conventional offset ink systems than for modern UV-curing ink systems or for coatings. The different ones. Cleaning fluids are often incompatible with each other and therefore must not be mixed together. For the printing operation follows that when changing the color system and the cleaning device supplied cleaning fluid must be changed, which is associated with an additional retooling and the loss of the detergent content of the supply lines.

Der Erfindung liegt die Aufgabe zugrunde, eine Reinigungsvorrichtung der eingangs genannten Art zu schaffen, die bei einem Wechsel des Farbsystems keinen besonderen Umrüstaufwand erfordert und Verluste an Reinigungsfluid hierbei vermeidet.The invention has for its object to provide a cleaning device of the type mentioned above, which requires no special conversion work and changes losses of cleaning fluid avoids this when changing the color system.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß wenigstens zwei voneinander getrennte Zuführungen für Reinigungsfluid vorgesehen sind. Wobei jede Zuführung über eine eigene Förderleitung mit einem eigenen Vorratsbehälter verbunden ist.The object is achieved in that at least two separate feeds are provided for cleaning fluid. Each feeder is connected via its own delivery line with its own storage container.

Die erfindungsgemäße Reinigungsvorrichtung ermöglicht den Einsatz unterschiedlicher Reinigungsfluids ohne besondere Umstellungsmaßnahmen. Bei der Umstellung des Druckbetriebs auf ein anderes Farbsystem kann daher der Austausch des Behälters für Reinigungsfluid und der Wechsel des Leitungsinhalts in den Zuführleitungen der Reinigungsvorrichtung entfallen. Hiermit verbunden sind die Einsparungen von Waschmittel und Umrüstzeit, die Gefahr einer versehentlichen Vermischung unverträglicher Waschmittel im Leitungssystem und eventuell dadurch bedingte Störungen werden vermieden, die Betriebssicherheit wird erhöht. Werden für unterschiedliche Zwecke bestimmte, jedoch miteinander verträgliche Reinigungsfluids eingesetzt, so besteht bei der erfindungsgemäßen Reinigungsvorrichtung auch die Möglichkeit, beide Reinigungsfluids gleichzeitig zu verwenden.The cleaning device according to the invention allows the use of different cleaning fluids without special conversion measures. When changing over the printing operation to another color system, therefore, the replacement of the container for cleaning fluid and the change of the line contents in the supply lines of the cleaning device can be omitted. Linked to this are the savings of detergent and changeover time, the risk of accidental mixing of incompatible detergents in the pipe system and possibly resulting disturbances are avoided, the reliability is increased. If certain, but mutually compatible, cleaning fluids are used for different purposes, it is also possible for the cleaning device according to the invention to use both cleaning fluids at the same time.

FIG. 2
a cleaning device according to the invention with a washing roller and a rotatable and two fixed feeds for cleaning fluid.

Die in Figur 1 gezeigte Reinigungsvorrichtung ist an einem Zylinder 1, beispielsweise einem Gummituchzylinder, Formzylinder oder Druckzylinder einer Druckmaschine angeordnet. Die Reinigungsvorrichtung besitzt ein Gehäuse 2 von annähernd rechteckigem Querschnitt, das sich über die gesamte Breite des Zylinders 1 erstreckt. Das Gehäuse 2 besteht aus einem Gehäuseoberteil 3 und einem daran lösbar angebrachten Gehäuseunterteil 4. An dem Gehäuseunterteil 4 befindet sich ein Ablauf 5. Das Gehäuse 2 weist eine der zu reinigenden Mantelfläche des Zylinders 1 zugewandte Öffnung 6 auf, durch welche eine in dem Gehäuse 2 drehbar gelagerte Waschwalze 7 soweit herausragt, daß sie in der in Figur 1 gezeigten Anstellposition der Reinigungsvorrichtung mit dem Zylinder 1 in Kontakt ist. Die Waschwalze 7 ist durch einen Antrieb in Pfeilrichtung antreibbar.The cleaning device shown in Figure 1 is arranged on a cylinder 1, for example a blanket cylinder, forme cylinder or printing cylinder of a printing press. The cleaning device has a housing 2 of approximately rectangular cross-section, which extends over the entire width of the cylinder 1. The housing 2 comprises an upper housing part 3 and a lower housing part 4 releasably attached thereto. A drain 5 is located on the lower housing part 4. The housing 2 has an opening 6 facing the cylindrical surface 1 to be cleaned, through which one in the housing 2 rotatably mounted washing roller 7 protrudes so far that it is in the setting position of the cleaning device shown in Figure 1 with the cylinder 1 in contact. The washing roller 7 can be driven by a drive in the direction of the arrow.

Parallel zur Waschwalze 7 erstrecken sich in dem Gehäuse 2 ein erstes Sprührohr 8 zur Zuführung eines ersten Reinigungsfluids, ein zweites Sprührohr 9 zur Zuführung eines zweiten Reinigungsfluids und ein drittes Sprührohr 10 zur Zuführung von Wasser. Die Sprührohre weisen eine Vielzahl kleiner Öffnungen oder Düsen auf, die in regelmäßigen Abständen voneinander über die gesamte Länge der Sprührohre verteilt sind. Die Sprührohre 8, 9 sind dem oberen Bereich der Waschwalze 7 benachbart und befinden sich in einem Abstand von dieser. Das Sprührohr 10 liegt der Kontaktstelle der Waschwalze 7 mit dem Zylinder 1 gegenüber und greift in die von Borsten gebildete Außenkontur der Waschwalze 7 ein. Hierdurch erfüllt das Sprührohr 10 zusätzlich die Funktion eines Abstreifers. Von den Sprührohren 8, 9, 10 führen Zuführleitungen 11, 12, 13 zu einem als 3/3-Wege-Ventil ausgebildeten Ventilblock 14, dem aus drei voneinander getrennten Vorratsbehältern 15, 16, 17 über drei voneinander unabhängige Pumpen 18, 19, 20 die beiden Reinigungsfluide und Wasser zugeführt werden. Die Sprührohre 8, 9, 10 sind um ihre Längsachse drehbar an dem Gehäuse 2 gelagert und mit außerhalb der Reinigungsvorrichtung angeordnetem Stellantrieben gekoppelt. Hierdurch können die Sprührohre 8, 9, 10 in verschiedene Arbeitspositionen gedreht werden, wie dies im einzelnen in DE 298 19 374 U1 beschrieben ist.Parallel to the washing roller 7 extend in the housing 2, a first spray tube 8 for supplying a first cleaning fluid, a second spray tube 9 for supplying a second cleaning fluid and a third spray tube 10 for supplying water. The spray tubes have a plurality of small openings or nozzles which are distributed at regular intervals from one another over the entire length of the spray tubes. The spray tubes 8, 9 are adjacent to the upper portion of the washing roller 7 and are at a distance therefrom. The spray tube 10 is the contact point of the washing roller 7 with the cylinder 1 opposite and engages in the bristle formed outer contour of the washing roller 7 a. As a result, the spray tube 10 additionally fulfills the function of a scraper. From the spray pipes 8, 9, 10 lead supply lines 11, 12, 13 to a 3/3-way valve valve block 14, which consists of three separate reservoirs 15, 16, 17 via three independent pumps 18, 19, 20th the two cleaning fluids and water are supplied. The Spray tubes 8, 9, 10 are rotatably mounted about the longitudinal axis of the housing 2 and coupled with arranged outside the cleaning device actuators. In this way, the spray tubes 8, 9, 10 are rotated in different working positions, as described in detail in DE 298 19 374 U1.

Der Ventilblock 14 ist über die Maschinensteuerung in drei Stellungen schaltbar. In jeder Stellung ist eine andere der Zuführleitungen 11, 12, 13 mit der ihr zugeordneten Pumpe 18, 19, 20 und dem ihr zugeordneten Vorratsbehälter 15, 16, 17 verbunden. Bei der in der Zeichnung gezeigten Mittelstellung des Ventilblocks 14 ist die Verbindung von dem Vorratsbehälter 16 zum Sprührohr 9 offen und die Verbindung von den Vorratsbehältern 15, 17 zu den Sprührohren 8, 10 gesperrt. Es kann daher nur das in dem Behälter 16 befindliche, beispielsweise für Offset-Farbe bestimmte Reinigungsfluid über das Sprührohr 9 der Sprühvorrichtung zugeführt werden. Soll ein anderes Reinigungsfluid aus dem Vorratsbehälter 15 oder Wasser aus dem Vorratsbehälter 17 zugeführt werden, so wird eine entsprechende Betätigung des Ventilblocks 14 durch die Maschinensteuerung erforderlich. Anstelle des Ventilblocks 14 können selbstverständlich auch andere Ventilsteuerungen, beispielsweise drei einzelne, voneinander unabhängig schaltbare Wegeventile vorgesehen sein. Diese können derart ansteuerbar sein, daß gleichzeitig aus zwei oder drei Sprührohren die entsprechenden Medien zuführbar sind.The valve block 14 is switchable via the machine control in three positions. In each position, another of the supply lines 11, 12, 13 with its associated pump 18, 19, 20 and its associated reservoir 15, 16, 17 is connected. In the middle position of the valve block 14 shown in the drawing, the connection from the reservoir 16 to the spray tube 9 is open and the connection from the storage containers 15, 17 to the spray tubes 8, 10 is blocked. Therefore, only the cleaning fluid in the container 16, for example for offset ink, can be supplied via the spray tube 9 to the spray device. If another cleaning fluid from the reservoir 15 or water from the reservoir 17 are supplied, a corresponding actuation of the valve block 14 by the machine control is required. Instead of the valve block 14, of course, other valve controls, for example, three individual, independently switchable valves can be provided. These can be controlled so that the same media can be fed from two or three spray tubes simultaneously.

Bei der in Figur 2 gezeigten Reinigungsvorrichtung, die in ihrem grundsätzlichen Aufbau der Reinigungsvorrichtung gemäß Figur 1 gleicht, ist nur das obere Sprührohr 8 drehbar. Die beiden anderen Sprührohre 9, 10 sind fest an dem Gehäuse 2 angeordnet. Auch das Sprührohr 10 befindet sich in einem Abstand von der Außenkontur der Waschwalze 7. Die Abstreiffunktion übernimmt stattdessen ein aus einem zylindrischen Stab bestehender Abstreifer 21, der zwischen den Sprührohren 9, 10 angeordnet und an dem Gehäuse 2 befestigt ist. Die Zuführung der beiden Reinigungsfluide und des Wassers erfolgt wie bei dem Ausführungsbeispiel gemäß Figur 1 aus voneinander getrennten Vorratsbehältern über die getrennten Zuführleitungen 11, 12, 13.In the cleaning device shown in Figure 2, which is similar in its basic structure of the cleaning device of Figure 1, only the upper spray tube 8 is rotatable. The two other spray pipes 9, 10 are fixedly arranged on the housing 2. Also, the spray tube 10 is located at a distance from the outer contour of the washing roller 7. The Abstreiffunktion takes over instead of a cylindrical Rod existing scraper 21 which is disposed between the spray tubes 9, 10 and fixed to the housing 2. As in the exemplary embodiment according to FIG. 1, the two cleaning fluids and the water are supplied from separate storage containers via the separate supply lines 11, 12, 13.
