Abstract

An inking device for a printing machine has an ink rail device, to which the ink is fed from an ink feed device through an ink supply line. In order to be able to carry out a print requiring only a very small amount of ink with small ink losses, coupling means are provided on the ink rail device and on the ink supply line for their detachable connection. In this case, instead of the ink supply line, an ink cartridge provided with corresponding coupling means can optionally be coupled on. The ink cartridge then has additional coupling means for the connection of a pressurised air feed line. <IMAGE>

Description

Die Erfindung betrifft ein Farbwerk mit einem Kammerrakel, dem Farbe durch eine Farbleitung von einer Farbzuführvorrichtung zugeführt wird.The invention relates to an inking unit with a chambered doctor blade, to which ink is fed through an ink line from an ink supply device.

Der Erfindung liegt die Aufgabe zugrunde, ein Farbwerk dieser Gattung so auszubilden, daß ein nur eine sehr kleine Farbmenge benötigender Druck mit geringen Farbverlusten durchgeführt werden kann.The invention has for its object to design an inking unit of this type so that a print requiring only a very small amount of ink can be carried out with little color loss.

Erfindungsgemäß wird diese Aufgabe durch Anwendung der Merkmale des Kennzeichens des Anspruchs 1 gelöst.According to the invention, this object is achieved by applying the features of the characterizing part of claim 1.

Weitere Merkmale und Vorteile ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung zweier Ausführungsbeispiele anhand der Zeichnung. Auf dieser zeigt

  • Fig. 1 eine schematische Seitenansicht eines Rakelfarbwerkes in der normalen Betriebsposition,
  • Fig. 2 das Farbwerk gemäß Fig. 1 nach Ümrüstung für einen nur wenig Farbe benötigenden Druck,
  • Fig. 3 eine Einzelheit einer Variante zur Anordnung gemäß Fig. 2 in einer Ansicht und
  • Fig. 4 einen Schnitt durch eine weitere Farbpatrone.
Further features and advantages emerge from the subclaims and the following description of two exemplary embodiments with reference to the drawing. On this shows
  • 1 is a schematic side view of a doctor blade inking unit in the normal operating position,
  • 2 shows the inking unit according to FIG. 1 after refitting for a print requiring only little ink,
  • Fig. 3 shows a detail of a variant of the arrangement of FIG. 2 in a view and
  • Fig. 4 shows a section through another color cartridge.

Das Rakelfarbwerk gemäß Fig. 1 umfaßt ein Kammerrakel 1 mit einem Träger 2 und einer Farbzuführvorrichtung 3. Das Kammerrakel 1 ist mit der Farbzuführvorrichtung 3 über eine flexible Farbleitung 4 verbunden. Das eine Ende der Farbleitung ist mittels einer Kupplung 5, beispielsweise einer Bajonett-Kupplung oder einer Kupplung mit Überwurfmutter, am Träger 2 des Kammerrakels 1 lösbar befestigt. Das andere Ende der Farbleitung 4 kann wie beim Ausführungsbeispiel fest an der Farbzuführvorrichtung angeschlossen oder ebenfalls über eine Kupplung mit dieser lösbar verbunden sein. Das Kammerrakel 1 wirkt mit einer Rasterwalze 6 zusammen.1 comprises a chambered doctor blade 1 with a carrier 2 and an ink supply device 3. The chambered doctor blade 1 is connected to the ink supply device 3 via a flexible ink line 4. One end of the paint line is by means of a coupling 5, for example a bayonet coupling or a coupling with a union nut, releasably attached to the carrier 2 of the chamber doctor blade 1. The other end of the paint line 4 can, as in the exemplary embodiment, be permanently connected to the paint feed device or can also be detachably connected to it via a coupling. The chambered doctor blade 1 interacts with an anilox roller 6.

Vor der Rasterwalze 6 ist zum Anschluß des Kammerrakels 1 eine Halterung 7 vorgesehen. Die Halterung 7 sitzt auf einer Traverse 8, die an beiden Enden an Seitenwänden der Druckmaschine drehbar gelagert ist, und umfaßt zwei auf die Traverse im Abstand von­einander aufgesetzte Halter 9, die je zwei Halteransätze 10 aufweisen. In die Halteransätze 10 können zwei Bolzen 11, die fest am Träger 2 befestigt sind, eingehängt werden. An der Traverse 8 ist weiterhin neben diesem Halter 9 je ein mittels eines Handhebels 12 drehbarer Exzenter 13 gelagert, der auf die Oberseite des Trägers 2 einwirkt und dadurch die Bolzen 11 in fester Anlage an den Halter­ansätzen 10 halten kann.In front of the anilox roller 6, a holder 7 is provided for connecting the chamber doctor blade 1. The holder 7 is seated on a crossmember 8, which is rotatably supported at both ends on the side walls of the printing press, and comprises two holders 9 placed on the crossmember at a distance from one another, each of which has two holder approaches 10. Two bolts 11, which are firmly attached to the carrier 2, can be suspended in the holder lugs 10. In addition to this holder 9, an eccentric 13 which can be rotated by means of a hand lever 12 is also mounted on the crossmember 8, which acts on the upper side of the carrier 2 and can thereby hold the bolts 11 in firm contact with the holder lugs 10.

Unterhalb der Unterkante jeder Rasterwalze 6 ist eine weitere Halterung vorgesehen, die eine Tragplatte 14 und eine weitere Traverse 15 umfaßt. Sowohl die Tragplatte 14 als auch die Traverse 15 sind an beiden Enden an den Seitenwänden der Druckmaschine angeschlossen. Die Tragplatte 14 dient zur Halterung der Farbzuführvorrichtung 3, während an der Traverse 15 eine Hauptwelle 16 gelagert ist, die über Kegelzahnräder 17, 18 eine Abtriebswelle 19 antreibt. Die Abtriebswelle 19 steht über eine lösbare Kupplung 20, beispielsweise eine Klauenkupplung, mit einer Antriebswelle 21 für eine Farbpumpe 22 der Farbzuführvorrichtung in Verbindung. Die Farbzuführvorrichtung 3 weist weiterhin eine Farbwanne 23 auf, in der die zu druckende Farbe bevorratet ist.A further holder is provided below the lower edge of each anilox roller 6, which includes a support plate 14 and a further cross member 15. Both the support plate 14 and the cross member 15 are connected at both ends to the side walls of the printing press. The support plate 14 serves to hold the ink supply device 3, while a main shaft 16 is mounted on the cross member 15, which drives an output shaft 19 via bevel gears 17, 18. The output shaft 19 is connected via a releasable clutch 20, for example a claw clutch, to a drive shaft 21 for an ink pump 22 of the ink supply device. The ink feed device 3 also has an ink tray 23 in which the ink to be printed is stored.

Diese Anordnung ist zum Verdrucken einer größeren Farbmenge geeignet und vorgesehen.This arrangement is suitable and intended for printing a larger amount of ink.

Soll eine geringere Farbmenge verdruckt werden, kann mittels der lösbaren Kupplung 5 eine Farbpatrone 24 an das Kammerrakel 1 angekuppelt werden, wie Fig. 2 zeigt. Die Farbpatrone 24 weist ein Steigrohr 25 auf, das in die patronenseitige Kupplungshälfte der Kupplung 5 mündet und mit dem Farbe durch ein Rohr 26 dem Kammerrakel 1 zugeführt werden kann. In die Farbpatrone 24 mündet ein weiterer Stutzen 27, an dem die eine Hälfte einer Kupplung 28 sitzt. Die andere Hälfte der Kupplung 28 bildet das Ende einer Druckluftzuleitung 29, die zumindest partiell ebenfalls flexibel ausgebildet ist. In der Druckluftzuleitung 29 sitzt weiterhin ein Drosselventil 30, dessen Drosselwirkung mittels eines Stellrädchens 31 einstellbar ist. Die Farbpatrone 24 ist oben durch einen Deckel 32 abgeschlossen, der zum Nachfüllen von Farbe in die Farbpatrone 24 abschraubbar sein kann.If a smaller amount of ink is to be printed, an ink cartridge 24 can be coupled to the chamber doctor blade 1 by means of the releasable coupling 5, as shown in FIG. 2. The ink cartridge 24 has a riser pipe 25 which opens into the cartridge-side coupling half of the coupling 5 and can be supplied with the paint through a pipe 26 to the chambered doctor blade 1. In the color cartridge 24 opens another nozzle 27 on which one half of a coupling 28 is seated. The other half of the coupling 28 forms the end of a compressed air supply line 29, which is also at least partially flexible. In the compressed air supply line 29 there is also a throttle valve 30, the throttling effect of which can be adjusted by means of a setting wheel 31. The color cartridge 24 is closed at the top by a cover 32 which can be unscrewed into the color cartridge 24 for refilling paint.

Innerhalb des Kammerrakels 1 ist ein Steg 33 vorgesehen, der von der Oberseite 34 ausgeht, sich über die ganze Breite des Kammmerrakels 1 erstreckt und über der Unterseite 35 einen schmalen Durchtrittsschlitz offen läßt.Within the chambered doctor blade 1, a web 33 is provided, which extends from the upper side 34, extends over the entire width of the chambered doctor blade 1 and leaves a narrow passage slot open above the lower side 35.

Weiterhin ist eine Farbauffangwanne 36 vorgesehen, die bei entfernter Farbzuführvorrichtung 3 mittels Stutzen 37 auf die Traverse 15 aufsetzbar ist, oder direkt am Kammerrakel 1 und Träger 2 befestigt wird.Furthermore, an ink collecting trough 36 is provided which, when the ink supply device 3 is removed, can be placed on the crossmember 15 by means of a connecting piece 37, or is attached directly to the doctor blade 1 and support 2.

Zur Durchführung eines nur eine geringe Farbmenge benötigenden Druckes wird die Kupplung 5 gelöst und die Farbzuführvorrichtung 3 von der Tragplatte 14 abgenommen. Anschließend wird die Farbauffangwanne 36 auf die Traverse 15 aufgesetzt und die Farbpatrone 24 mittels der Kupplung 5 an das Kammerrakel 1 angeschlossen. Die Farbpatrone 24 wird dann über die Kupplung 28 mit der Druckluftzuleitung 29 verbunden. Wird nunmehr die Farbpatrone 24 mit Druckluft beaufschlagt, so drückt diese die Farbe über das Steigrohr 25 und das Rohr 26 in die Kammerrakel, über die die Rasterwalze 6 eingefärbt wird. Vom Kammerrakel abtropfende Farbe wird von der Farbauffangwanne 36 aufgenommen. Sinkt der Farbspiegel in der Farbpatrone 24 unter die Unterkante des Steigrohres 25, bläst Druckluft direkt durch das Steigrohr 25 und das Rohr 26 in die Kammerrakel. Hier stellt der Steg 33 sicher, daß ein Teil der in der Kammerrakel befindlichen Farbe noch der Rasterwalze 6 zugeführt wird, bis der Farbspiegel im Raum zwischen dem Rohr 26 und dem Steg 33 die Unterkante des Steges 33 erreicht hat. Es ist also eine sehr weitgehende Ausnutzung der geringen, in der Farbpatrone 24 enthaltenen Farbmenge möglich.To carry out a print requiring only a small amount of ink, the coupling 5 is released and the ink supply device 3 is removed from the support plate 14. Then the ink drip pan 36 is placed on the cross member 15 and the ink cartridge 24 is connected to the chamber doctor blade 1 by means of the coupling 5. The ink cartridge 24 is then connected to the compressed air supply line 29 via the coupling 28. If the ink cartridge 24 is now pressurized with compressed air, it presses the ink via the riser pipe 25 and the pipe 26 into the chamber doctor blade, via which the anilox roller 6 is inked. From the doctor blade dripping paint is taken up by the ink collecting tray 36. If the ink level in the ink cartridge 24 drops below the lower edge of the ascending pipe 25, compressed air blows directly through the ascending pipe 25 and the pipe 26 into the doctor blade. Here, the web 33 ensures that part of the ink in the chamber doctor blade is still fed to the anilox roller 6 until the ink level in the space between the tube 26 and the web 33 has reached the lower edge of the web 33. A very extensive utilization of the small amount of ink contained in the ink cartridge 24 is therefore possible.

Anstelle eines einstellbaren Drosselventiles 30 kann es auch ausreichen, in den patronenseitigen Teil der Kupplung 5 eine Dichtscheibe 38, vgl. Fig. 3, einzulegen, die eine der erforderlichen Drosselwirkung angepaßte Durchtrittsöffnung 39 aufweist.Instead of an adjustable throttle valve 30, it may also be sufficient to insert a sealing washer 38 into the cartridge-side part of the coupling 5, cf. 3, which has a passage opening 39 adapted to the required throttling effect.

In Fig. 4 ist ein weiteres Ausführungsbeispiel einer Farbpatrone 40 dargestellt. Diese Farbpatrone weist einen Stutzen 41 zur Zufuhr der Druckluft auf, der unmittelbar über ihrem Boden 42 mündet. Im oberen Bereich ist ein weiterer Stutzen 43 für die Farbableitung vorgesehen. Innerhalb der Farbpatrone ist ein Kolben 44 abdichtend geführt, auf dessen Oberseite eine Druckfeder 45 einwirkt, deren anderes Ende sich an einem Deckel 46 der Patrone 40 abstützt. In dem die Druckfeder 45 aufnehmenden Raum oberhalb des Kolbens 44 befindet sich der Farbvorrat. Die beiden Stutzen 41, 43 dienen dabei gleichzeitig zur Begrenzung des Weges des Kolbens 44.4 shows another embodiment of a color cartridge 40. This color cartridge has a nozzle 41 for supplying the compressed air, which opens directly above its bottom 42. In the upper area a further nozzle 43 is provided for the color derivation. A piston 44 is sealingly guided within the color cartridge, on the upper side of which a compression spring 45 acts, the other end of which is supported on a cover 46 of the cartridge 40. The ink supply is located in the space accommodating the compression spring 45 above the piston 44. The two connecting pieces 41, 43 serve simultaneously to limit the path of the piston 44.

Wird der Raum unterhalb des Kolbens 44 mit Druckluft beaufschlagt, so drückt der Kolben 44 die Farbe unter Zusammendrücken der Druckfeder 45 durch den Stutzen 43 zum Kammerrakel. Mit dieser Ausführung ist ein Durchblasen der Druckluft in das Kammerrakel 1 ausgeschlossen. Dagegen ist die Restfarbmenge, die nicht mehr zum Druck verwendet werden kann, etwas größer als bei der Anordnung gemäß Fig. 2. Beim Abstellen des Luftdrucks bewirkt die Druckfeder 45 mit einem Zurückstellen des Kolbens 44 auch ein Zurücksaugen von Farbe aus dem Kammerrakel.If the space below the piston 44 is pressurized with compressed air, the piston 44 presses the paint by compressing the compression spring 45 through the nozzle 43 to the chamber doctor. With this design, blowing the compressed air into the chamber doctor blade 1 is excluded. In contrast, the amount of residual ink that can no longer be used for printing is somewhat larger than in the arrangement according to FIG. 2. When the air pressure is switched off, the compression spring 45 also causes ink to be sucked back out of the chambered doctor blade when the piston 44 is reset.
