Abstract

In inking systems working without ink circulation, special importance is attacked to sealing off the inking chamber. With the present proposal, the lateral sealing-off of an inking chamber equipped with an upper and a lower doctor can be improved in that the sealing lips are provided with oblique grooves which generate a conveying effect counter to a possible lateral outflow of ink.

Description

Vorrichtung zum AbschließenDevice for locking

einer Farbauftragskammer für Flexo- und Tiefdruckmaschinen Die Zusatzanmeldung betrifft eine vorteilhafte Ausführung der seitlichen Abdichtungen des Farbantragsraumes 7 und eine Vorrichtung zum Transportieren von Farbe und Reinigungsmittel durch das Farbführungs- und Verteilungssystem.an inking chamber for flexographic and gravure printing machines the Additional application relates to an advantageous embodiment of the side seals of the paint application room 7 and a device for transporting paint and cleaning agents through the paint feed and distribution system.

Gemäß Anspruch 9 der Hauptanmeldung bilden die Rakel 8 und 9 die obere und untere Begrenzung des Farbantragraumes 7* Da mit zunehmendem Rakelverschleiß eine Positionsveränderung der Farbkammer 2 gegenüber der Rasterwalze 1 stattfindet, wird vorgeschlagen, die seitliche Abdichtung so auszubilden, daß die Dichtleisten der Positionsänderung ohne Änderung des Anpreßdruckes folgen Im einzelnen ist eine vorschlagsgemäße Ausführung in Fig.12( und FigZdr dargestellt.According to claim 9 of the main application, the doctor blades 8 and 9 form the upper one and lower limit of the ink application space 7 * Da with increasing squeegee wear a change in position of the ink chamber 2 with respect to the anilox roller 1 takes place, it is proposed to design the side seal so that the sealing strips follow the change in position without changing the contact pressure the proposed design is shown in Fig. 12 (and FigZdr.

In die Schwalbenschwanznut 15 wird beiderseits ein Dichtleistenträgerteil 14 eingeschoben. Die Dichtleiste 17 wird durch die Federn 16 in Richtung Rasterwalze angedrückt, Auf der Gleitfläche der Dichtleiste befinden sich flache, schräg angeordnete Rillen 18, die durch die Umlaufbewegung der Rasterwalze 1 eine Förderwirkung auf die nach außen drängende Farbe in Richtung Farbkammer 7> ausüben und damit eine verbesserte Dichtwirkung erzielen. Das Dichtungsplättchen 19 verhindert das seitliche Austreten von Farbe oder Reinigungsflüssigkeit durch das Dichtungsträgerteil 14.In the dovetail groove 15, a sealing strip support part is placed on both sides 14 inserted. The sealing strip 17 is moved by the springs 16 in the direction of the anilox roller pressed, on the sliding surface of the sealing strip are flat, inclined Grooves 18, which have a conveying effect through the revolving movement of the anilox roller 1 exert the outward pushing color in the direction of the color chamber 7> and thus a achieve improved sealing effect. The sealing plate 19 prevents the lateral Leakage of paint or cleaning fluid through the seal carrier part 14.

Gemäß Anspruch 4 der Hauptanmeldung kann der Druck zum Transportieren der Farbe oder der Reinigungsflüssigkeit durch eine drehzahlvariable Tauchpumpe erzeugt werden Zur weiteren Vereinfachung beim Farbwechsel wird vorgeschlagen, sowohl die Farbe als auch die Reinigungsflüssigkeit so in eine durch Luft oder Gas beaufschlagte Druckkammer zu stellen, daß die jeweils benötigte Flüssigkeit durch Einschieben einer Röhre durch eine Dichtmuffe in den einen oder anderen Flüssigkeitsbehälter zur Farbkammer gepumpt wird. Der Pumpdruck kann in bekannter Weise durch ein Druckreduzierventil eingestellt werden.According to claim 4 of the main application, the pressure can be used for transport the paint or the cleaning fluid by a variable-speed submersible pump To further simplify the color change, it is suggested both the paint as well as the cleaning liquid in one acted upon by air or gas Provide pressure chamber that the required liquid by pushing a tube through a sealing sleeve into one or the other liquid container is pumped to the ink chamber. The pump pressure can be adjusted in a known manner by means of a pressure reducing valve can be set.
