Vorrichtung zum Reinigen der Gummitücher von Offset - Druckmaschinen.Device for cleaning the rubber blankets of offset printing machines.

BeschreibungDescription

Die Erfindung bezieht sich auf eine Vorrichtung zum Reinigen der Zylinder in der Offset - Druckmaschine, die mit einem Gummituch bespannt sind, wobei vor jedem Gummituch ein Reinigungstuch über eine Wickelvorrichtung schrittweise vorbeigeflihrt wird. Ein doppeltes Düsensystem besprüht von hinten das Reinigungstuch wahlweise mit Reinigungsmittel oder mit Wasser. Offset - Druckmaschinen haben den Nachteil, daß sich die Druckfarbe auf das Papier übertragende Gummituches der Zylinder während des Drückens mit Farbresten und anderen Verunreinigungen wie z.B. Papierstaub verschmutzt und daß dadurch die Druckqualität leidet. Eine Reinigung der Gummitücher muß deshalb vorgenommen werden. Die landläufig bekannte Reinigungsart besteht darin, daß die Druckmaschine angehalten wird, um die verschmutzten Gummitücher von Hand mit Putztüchern und Reinigungsflüssigkeit zu waschen. Dieser zeit- und personalaufwendige Vorgang, der mehrmals während einer Schichtausgeführt werden muß,ergibt einen sehr hohen Produktionsausfall, da alle Druckwerke einzeln von Hand gereinigt werden müssen.The invention relates to a device for cleaning the cylinders in the offset printing machine, which are covered with a rubber blanket, whereby a cleaning cloth is guided step by step in front of each rubber blanket over a winding device. A double nozzle system sprays the cleaning cloth from behind with either cleaning agent or water. Offset printing machines have the disadvantage that the printing ink of the rubber blanket of the cylinder, which transfers to the paper, becomes dirty with ink residues and other contaminants such as paper dust during printing, and this affects the print quality. The rubber blankets must therefore be cleaned. The commonly known method of cleaning consists in stopping the printing machine in order to wash the dirty rubber blankets by hand with cleaning cloths and cleaning fluid. This time-consuming and labor-intensive process, which has to be carried out several times during a shift, results in a very high loss of production, since all printing units have to be cleaned individually by hand.

Eine Kunsstoff beschichtete Metalleiste drückt das Reinigungstuch gegen das Gummituch. Ein in einem Metallkörper eingebetteter, aufblasbarer, elastischer Schlauch schiebt diese Metalleiste in den Arbeitsbereich vor das Gummituch. Da die Metalleiste über ihre Formgebung einen unverrückbaren Endanschlag hat, wird der Zustellweg genau angefahren. Das hat den Vorteil, daß selbst breite Kanäle in den Gummituchzylindern problemlos überbrückt werden können, z.B. bei Bogenoffsetmaschinen. Dieser so ablaufende Arbeitsvorgang kann während des Laufes der Maschine an allen Druckwerken gleichzeitig vorgenommen werden, ohne das Papier bedruckt wird, also kein Makulaturanfall ensteht. Dadurch, daß alle Druckwerke gleichzeitig gereinigt werden können, ergibt sich eine Zeitersparnis von großem Ausmaß ( ca. 80% ), die den Produktionsausfall erheblich mindert.A plastic-coated metal bar presses the cleaning cloth against the rubber blanket. An inflatable, elastic hose embedded in a metal body pushes this metal bar into the working area in front of the rubber blanket. Since the metal bar has an immovable end stop due to its shape, the feed path is precisely followed. This has the advantage that even wide channels in the rubber blanket cylinders can be bridged without any problem, e.g. in sheet-fed offset machines. This work process can be carried out on all printing units simultaneously while the machine is running, without printing on paper, so there is no waste. The fact that all printing units can be cleaned at the same time results in a huge time saving (approx. 80%), which significantly reduces production downtime.

Hinzu kommen Ersparnisse an Reinigungsmitteln und Handputztüchern. Da der Vorgang automatisch abläuft, sei noch erwähnt, daß das Unfallrisiko gleich „Null" ist und Personalkosten gespart werden können.There are also savings on cleaning agents and hand cleaning cloths. Since the process is automatic, it should also be mentioned that the risk of accidents is "zero" and personnel costs can be saved.

Der in einem Metallkörper ( 2 ) eingebettete, elastische, aufblasbare Schlauch (3) schiebt die kunstoffbeschichtete Metalleiste (7) an den Endanschlag des Metallkörpers (4) und gewährt somit eine genaue Position zum Gummituch, damit auch breite Kanüle überbrückt werden können. Um das Reinigunstuch genau positionieren zu können, ist diese starre Anordnung über die kunststoffbeschichtete Metallleiste (7) in Verbindung mit dem Festanschlag (4) erforderlich Die Achsen (5) und (6) dienen zur Aufnahme des Reinigungstuches.The elastic, inflatable hose (3) embedded in a metal body (2) pushes the plastic-coated metal strip (7) to the end stop of the metal body (4) and thus ensures a precise position to the rubber blanket so that even wide cannulas can be bridged. In order to be able to position the cleaning cloth precisely, this rigid arrangement over the plastic-coated metal strip (7) in conjunction with the fixed stop (4) is required. The axes (5) and (6) are used to hold the cleaning cloth.
