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 durch mindesten eine Zuleitung 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, connected by at least one supply line to a supply system is, which dosed the cleaning fluid and by means of compressed air the lance supplies.
Eine
derartige Reinigungsvorrichtung ist aus der
Die Realisierung eines gleichmäßigen Sprühbildes wird jedoch dadurch behindert, dass beim Ausblasen der Reinigungsfluidsäule sich diese mit der treibenden Luftsäule vermischt. Dabei wird das Reinigungsfluid mit Luft verwirbelt und zusätzlich an den Leitungs- bzw. Rohrwandungen sowie Umlenkstellen (z.B. Winkelanschlüssen) in partielle Fraktionen aufgelöst. Damit steht in dem Sprührohr kein homogenes Gemisch zum Versprühen zur Verfügung, sondern es liegen stochastisch entstandene, partiell unterschiedlich homogene Gemischfraktionen vor, durch die die einzelnen Düsen des Sprührohres unterschiedlich beaufschlagt werden, so dass ein gleichmäßiges Sprühbild nicht realisiert werden kann.The Realization of a uniform spray pattern However, it is hindered by the fact that when blowing the cleaning fluid column itself this with the driving air column mixed. The cleaning fluid is swirled with air and in addition the line or Pipe walls and deflection points (for example angle connections) in partial fractions dissolved. This is in the spray tube no homogeneous mixture for spraying to disposal, but there are stochastisch resulting, partially different homogeneous mixture fractions through which the individual nozzles of the spray pipe be applied differently, so that a uniform spray pattern is not can be realized.
In
der
Aufgabe der Erfindung ist es, eine bekannte Reinigungsvorrichtung so zu verändern, dass mit einfachen Mitteln stets ein gleichmäßiges Sprühbild realisiert wird.task The invention is to a known cleaning device so change, that with simple means always a uniform spray pattern is realized.
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 wird das aufgrund des Ausblasens mittels Druckluft stochastisch in partiell unterschiedlich homogene Fraktionen überführte Reinigungsfluid in ein homogenes Flüssigkeits-Luft-Gemisch überführt und damit ein gleichmäßiges Ausbringen des Reinigungsfluids über die Länge des Sprührohres realisiert.By the solution according to the invention becomes due to the blowing out by means of compressed air stochastic in partial different homogeneous fractions transferred cleaning fluid in a homogeneous liquid-air mixture transferred and thus a uniform spreading of the cleaning fluid the length of the spray tube realized.
