Abstract
Description
Die Erfindung betrifft eine Reinigungsvorrichtung für einen Zylinder oder eine Walze einer Druckmaschine mit mindestens einem sich über die Breite des Zylinders oder der Walze erstreckenden, ein Reinigungsfluid zuführenden Sprührohr, das mit einem Versorgungssystem verbunden ist, welches das Reinigungsfluid dosiert und mittels Druckluft dem Sprührohr zuführt.The The invention relates to a cleaning device for a cylinder or a Roller of a printing machine with at least one over the Width of the cylinder or roller extending, a cleaning fluid afferent spray tube, which is connected to a supply system which contains the cleaning fluid dosed and fed by compressed air to the spray tube.
Eine
derartige Reinigungsvorrichtung ist aus der
Die Realisierung eines gleichmäßigen Sprühbildes wird jedoch dadurch verhindert, dass die zwischen dem in dem Zwischenspeicher befindlichen Reinigungsfluid und den Düsen des Sprührohrs befindliche Luftsäule nicht schlagartig über die Düsen evakuiert werden kann. Das führt dazu, dass nahe der Einspeisungen in das Sprührohr das Reinigungsfluid bereits versprüht wird, während entfernt davon das Sprührohr noch entlüftet wird, wodurch insbesondere bei großformatigen Maschinen nur eine ungleichmäßige Benetzung der zu reinigenden Mantelflächen realisiert wird. Zur Beseitigung dieses Nachteils ist es bekannt, unterschiedlich große Düsenbohrungen verteilt über die Breite der Sprührohre vorzusehen. Das führt jedoch zu einem erhöhten Fertigungsaufwand, wobei durch diese Maßnahme nicht sichergestellt wird, dass bei jedem Betriebszustand ein gleichmäßiges Sprühbild realisiert wird.The Realization of a uniform spray pattern However, this is prevented by the fact that between the in the cache located cleaning fluid and the nozzles of the spray tube located air column not abruptly over the nozzles evacuated can be. Leading to that near the feeds into the spray tube, the cleaning fluid already sprayed will, while removed from it the spray pipe still vented becomes, whereby in particular with large-format machines only one uneven wetting the lateral surfaces to be cleaned is realized. To overcome this disadvantage, it is known different sizes nozzle bores spread over the width of the spray pipes provided. Leading however, to an increased Production costs, which is not ensured by this measure is that in every operating condition, a uniform spray pattern is realized.
Aufgabe der Erfindung ist es, eine bekannte Reinigungsvorrichtung so zu verändern, dass mit einfachen Mitteln in jedem Betriebszustand ein gleichmäßiges Sprühbild realisiert werden kann.task The invention is to a known cleaning device so change, that realized by simple means in any operating condition, a uniform spray pattern can be.
Erfindungsgemäß wird die Aufgabe durch eine Reinigungsvorrichtung nach den Merkmalen des Anspruchs 1 gelöst.According to the invention Task by a cleaning device according to the features of Claim 1 solved.
Durch die erfindungsgemäße Lösung ist es möglich, das Sprührohr beim Zuführen von Reinigungsfluid problemlos zu entlüften, so dass das Reinigungsfluid gleichzeitig versprüht und damit ein gleichmäßiges Sprühbild über das Sprührohr realisiert wird.By the solution according to the invention it is possible the spray tube when feeding of cleaning fluid to easily vent, leaving the cleaning fluid sprayed at the same time and thus a uniform spray pattern over the lance is realized.
Die Erfindung wird an einem Ausführungsbeispiel näher erläutert. In den zugehörigen Zeichnungen zeigenThe Invention is based on an embodiment explained in more detail. In the associated Drawings show
