Abstract
Die Erfindung betrifft eine Einrichtung zum Verhindern von Verschmutzungen von Greifersystemen, im Kanal u. ä beim Waschen an Druckzylindern von Druckmaschinen durch die Zylinderwascheinrichtung. DOLLAR A Aufgabe der Erfindung ist es, Verschmutzungen am Druckzylinder, ohne dass die Wascheinrichtung beim Waschprozess vom Druckzylinder weggesteuert wird, durch die Wascheinrichtung zu verhindern. DOLLAR A Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass im Kanal (1) des Druckzylinders (2) eine Walkleiste (7) mit einer Rakelspitze (8) fest angeordnet und die Rakelspitze (8) mit dem Waschtuch (4) beim Waschvorgang in Kontakt bringbar ist.The invention relates to a device for preventing contamination of gripper systems, in the channel u. When washing on printing cylinders of printing machines through the cylinder washing device. DOLLAR A object of the invention is to prevent contamination of the printing cylinder without the washing device is steered away from the printing cylinder during the washing process by the washing device. DOLLAR A According to the invention the object is achieved in that in the channel (1) of the printing cylinder (2) a Walkleiste (7) with a doctor blade (8) fixedly arranged and the doctor blade tip (8) with the washing cloth (4) brought into contact during the washing process is.
Description
Die Erfindung betrifft eine Einrichtung zum Verhindern von Verschmutzungen von Greifersystemen, im Kanal u. ä. beim Waschen an Druckzylindern von Druckmaschinen durch die Zylinderwascheinrichtung.The The invention relates to a device for preventing soiling of gripper systems, in the channel u. Ä. When washing on pressure cylinders of Printing machines through the cylinder washing device.
Druckzylinderwascheinrichtungen arbeiten z. B. mit einer aufblasbaren Gummilippe und einem darüber liegenden Waschtuch. Der Reinigungsvorgang erfolgt durch Anpressen des gefeuchteten Waschtuches an die bewegte Druckzylinderoberfläche.Printing cylinder washing devices work z. B. with an inflatable rubber lip and an overlying Wash cloth. The cleaning process is carried out by pressing the moistened washing cloth to the moving impression cylinder surface.
Beim Kanaldurchgang wird das mit Waschmittel und aufgenommener Farbe getränkte Waschtuch durch die Greiferrücken und die Kanalkante ausgewrungen und gibt seine Rück stände an die Mechanismen der Greifer und Auswerfer (bei Druckzylinder vor der Wendetrommel in S/W-Maschinen) ab.At the Passage through the duct will be done with detergent and absorbed paint impregnated Washing cloth through the gripper back and the channel edge wrung out and gives its back to the mechanisms of Gripper and ejector (for impression cylinder in front of the beater in B / W machines).
Nach dem Verdunsten der Waschmittel härtet die Farbe wieder aus und behindert zunehmend die Bewegung der Mechanismen. Eine Reinigung ist durch die schlechte Zugänglichkeit für entsprechende Schaber in dem verwinkelten Bauraum nur mit scharfen Reinigungsmitteln möglich, die gesundheitsschädlich sind und sich aggressiv gegenüber verschiedenen Bauteilen verhalten.To the evaporation of the detergent hardens the color again and increasingly obstructs the movement of the mechanisms. A cleaning is due to the poor accessibility for appropriate Scraper in the winding space only with sharp cleaning agents possible, the harmful are and are aggressive towards different ones Behave components.
In der Praxis ist es auch üblich, die Wascheinrichtung über den Zylinderkanal abzuheben. Dies hat den Nachteil, dass eine komplizierte Steuerung notwendig ist und ausserdem wird der Druckzylinder ab Greiferbereich nicht gewaschen.In In practice, it is also common the washing device over lift off the cylinder channel. This has the disadvantage of being a complicated one Control is necessary and also the pressure cylinder is off Gripper area not washed.
Aus
der
Ausgehend von diesen Nachteilen aus dem Stand der Technik ist es Aufgabe der Erfindung, Verschmutzungen am Druckzylinder, ohne dass die Wascheinrichtung beim Waschprozeß vom Druckzylinder weggesteuert wird, durch die Wascheinrichtung zu verhindern.outgoing Of these disadvantages of the prior art, it is the task of Invention, contamination on the printing cylinder, without the washing device during the washing process of Pressure cylinder is controlled away, through the washing device to prevent.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des 1. Anspruchs gelöst.According to the invention this Problem solved by the features of the first claim.
Die Anordnung einer Walkleiste im Kanal des Druckzylinders mit der aus dem Waschtuch beim Vorbeifahren an der Wascheinrichtung die Flüssigkeit herausgequetscht und Schmutzpartikel abgestrichen werden, hat den Vorteil, dass die Wascheinrichtung über den Kanal und dem Greifersystem nicht abgehoben zu werden braucht. Die Flüssigkeit selbst wird vorüber gehend bis zur Säuberung von der Walkleiste aufgenommen. Das Waschtuch ist beim Überfahren des Greifersystems weitestgehend trocken und schmutzfrei. Damit kann das Greifersystem, aber auch der Kanal durch das Waschtuch nicht beschmutzt oder anderweitig negativ beeinträchtigt werden.The Arrangement of a Walkbar in the channel of the printing cylinder with the off the washing cloth squeezed out the fluid when passing by the washing device and dirt particles are scraped off, has the advantage that the Washing device over the channel and the gripper system need not be lifted. The liquid itself is passing until the purge taken from the wallop The washcloth is when driving over of the gripper system largely dry and free of dirt. In order to Can the gripper system, but also the channel through the washing cloth not be soiled or otherwise adversely affected.
