Description

Die Erfindung bezieht sich auf einen Farbkasten für Offset- oder Hochdruckmaschinen, mit einer Farbdosiereinrichtung mit auf zonal unterschiedliche Farbspaltdicken zu einer Farbkastenwalze einstellbaren Dosierelementen, die von einer elastischen Folie überdeckt sind und mit Verschlußstücken, die beiderseits stirnseitig den Farbraum abschließen.The invention relates to an ink fountain for offset or High pressure machines, with a paint metering device to zonal different color gap thicknesses to one Ink fountain roller adjustable dosing elements by a elastic film are covered and with closures, that close off the color space on both sides.

Bei einer bekannten Ausführung dieser Art (DE 26 48 098 C3) überdeckt die elastische Folie die Dosierelemente und den Farbkasten über seine ganze Breite, so daß die eingefüllte Druckfarbe auch bei ihrem höchsten Stand nicht unter die Folie gelangen kann. Die Folie selbst läßt sich auf einfache Weise austauschen, muß jedoch nach ihrer Verwendung als Sondermüll entsorgt werden.In a known version of this type (DE 26 48 098 C3) the elastic film covers the dosing elements and the Color box over its entire width, so that the filled Even at its highest level, printing ink is not below the Foil can reach. The film itself can be easily Exchange way, but must be used after Hazardous waste.

Die Aufgabe vorliegender Erfindung ist es, die Kosten der Folie ansich und die Kosten für deren Entsorgung zu verringern und das Farbvolumen im Farbkasten zu verkleinern.The object of the present invention is to reduce the cost of Foil itself and the cost of its disposal too decrease and reduce the ink volume in the ink fountain.

Gemäß der Erfindung wird die Aufgabe dadurch gelöst, daß die beiden Verschlußstücke durch eine Traverse verbunden sind, die den Farbraum gegenüber der Farbkastenwalze begrenzt und daß die elastische Folie an der Traverse befestigt ist. Durch diese Lösung läßt sich die Breite der Folie wesentlich reduzieren, so daß die Kosten hierfür vermindert werden. Außerdem fällt entsprechend weniger Material für die Entsorgung an, so daß auch hierdurch eine Kosteneinsparung entsteht. Durch den begrenzten Farbraum läßt sich ein Auftragswechsel schneller durchführen und der Farbkastenwalze wird ständig frische Druckfarbe zugeführt. Auch das Einfüllen der Farbe und die Kontrolle des Füllstandes wird hierdurch günstig beeinflußt. According to the invention the object is achieved in that the two locking pieces are connected by a crossbar, which limits the ink space compared to the ink fountain roller and that the elastic film is attached to the crossbar. By this solution allows the width of the film to be significant reduce so that the cost of this is reduced. In addition, less material falls for them Disposal, so that this also saves costs arises. Due to the limited color space, one can Carry out job changes faster and the ink fountain roller fresh ink is fed continuously. Filling too the color and the control of the fill level is thereby favorably influenced.

In einer vorteilhaften Ausgestaltung ist an der Traverse eine Klemmleiste zum Festklemmen der elastischen Folie angeordnet. Hiermit ist ein Wechseln der Folie in kürzester Zeit möglich und nach dem Entleeren des Farbraums lassen sich die beiden Verschlußstücke mit der Traverse und der daran befestigten Folie leicht aus dem Farbkasten entnehmen und mit einer neuen Folie versehen. Hierdurch wird die Handhabung erleichtert und die Reinigungsarbeit, z. B. beim Farbwechsel, wesentlich verkürzt.In an advantageous embodiment, there is a on the crossmember Terminal strip arranged to clamp the elastic film. This enables the film to be changed in the shortest possible time and after emptying the color space, the two Locking pieces with the traverse and the attached Slightly remove the film from the ink fountain and use a new one Provided foil. This makes handling easier and the cleaning work, e.g. B. when changing colors, essential shortened.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen schematisch dargestellt.An embodiment of the invention is in the drawings shown schematically.

Es zeigt:

Fig. 1
einen Querschnitt durch den Farbkasten,
Fig. 2
eine Draufsicht auf den Farbkasten.
It shows:
Fig. 1
a cross section through the ink fountain,
Fig. 2
a top view of the ink fountain.

Der Farbkasten 1 ist über seine Länge mit einer Vielzahl zonenbreiten Dosierelementen 2 versehen, die von Farbdosiereinrichtungen 3 steuerbar sind. Die Dosierelemente 2 sind über eine elastische Folie 4 gegenüber einer Farbkastenwalze 5 auf unterschiedliche Farbspaltdicken einstellbar. An beiden Stirnseiten ist der Farbraum 6 von Verschlußstücken 7 begrenzt, die gegenüber der Farbkastenwalze 5 abgedichtet sind. Beide Verschlußstücke sind durch eine Traverse 8 fest miteinander verbunden, die den Farbraum 6 gegenüber der Farbkastenwalze 5 so begrenzt, daß nur ein relativ geringer Farbvorrat zum Einsatz kommt. Die beiden Verschlußstücke 7 mit der Traverse 8 sind in bekannter Weise am Farbkasten 1 befestigt.The ink fountain 1 has a large number over its length zone-wide metering elements 2 provided by Color metering devices 3 are controllable. The Dosing elements 2 are opposite each other via an elastic film 4 an ink fountain roller 5 to different ink gap thicknesses adjustable. The color space 6 is on both ends Closure pieces 7 limited to the Ink fountain roller 5 are sealed. Both locking pieces are firmly connected to each other by a traverse 8, the limited the ink space 6 compared to the ink fountain roller 5, that only a relatively small color supply is used. The two locking pieces 7 with the cross member 8 are in attached to the ink fountain 1 in a known manner.

Die elastische Folie 4 wird zwischen Farbkasten 1 und Traverse 8 hindurchgeführt und auf der dem Farbraum 6 gegenüberliegenden Seite mittels einer Klemmleiste 9 an der Traverse 8 festgeklemmt. Hierdurch wird mit Sicherheit ein Austreten der Druckfarbe aus dem Farbraum 6 verhindert. Auf beiden Seiten erstreckt sich die elastische Folie 4 bis unter die Verschlußstücke 7, so daß auch hier eine sichere Abdichtung des Farbraumes gewährleistet ist. Nach Lösen der Befestigung der beiden Verschlußstücke 7 läßt sich die komplette Einheit bestehend aus beiden Verschlußstücken 7, Traverse 8, Folie 4 und Klemmleiste 9 auf einfache Weise aus der Maschine entfernen, so daß Reinigungsarbeiten oder Folienwechsel auch außerhalb der Maschine durchgeführt werden können. Hierzu kann der Farbkasten 1 nach dem Entleeren der Farbe in bekannter Weise von der Farbkastenwalze 5 abgeschwenkt werden. Zum Dichtstellen der beiden Verschlußstücke 7, lassen sich diese an die Farbkastenwalze 5 anstellen. The elastic film 4 is between ink fountain 1 and Traverse 8 passed and on the color space 6 opposite side by means of a terminal block 9 on the Crossbar 8 clamped. This will definitely Prevention of the ink from the color space 6 prevented. On The elastic film 4 extends on both sides to below the closure pieces 7, so that here too a safe Sealing of the color space is guaranteed. After loosening the Attachment of the two closure pieces 7 can complete unit consisting of two locking pieces 7, Traverse 8, foil 4 and terminal block 9 in a simple manner remove the machine so that cleaning work or Foil changes can also be carried out outside the machine can. For this purpose, the ink fountain 1 after emptying the Color in a known manner from the ink fountain roller 5 be pivoted away. To seal the two Closure pieces 7, these can be on the ink fountain roller 5th hire.
