An eine Rasterwalze 1 eines Kurzfarbwerkes ist eine insgesamt mit 2 bezeichnete Kammerrakeleinrichtung anstellbar. Die Kammerrakeleinrichtung 2 kann aus einer Farbwanne 3 mit einem etwa U-förmigen Profil bestehen, welche sich mit einer Länge l unterhalb und achsparallel zur Rasterwalze 1 erstreckt. Die Länge l der Farbwanne 3 kann ein Viertel der Gesamtlänge der Rasterwalze 1 betragen, so daß vier verschiedene Farbwannen 3 unter der Rasterwalze 1 angeordnet sein können. Jede Farbwanne 3 weist stirnseitige Schließbleche 4, 6 auf, welche das U-Profil beidseitig z. B. mittels Schrauben verschließen. Die Schließbleche 4; 6 sind mit ihrer der Rasterwalze 1 zugewandten Seite der Peripherie der Rasterwalze 1 angepaßt. An beiden Schließblechen 4; 6 sind in achsparalleler Richtung zur Rasterwalze 1 sowie ins Innere der Kammerrakeleinrichtung 2 weisende Achszapfen 7; 8 befestigt, auf welchen über Kugellager 9; 11 beidendig eine Walze, z. B. Gummiwalze 12 rotierbar gelagert ist. Die Gummiwalze 12 weist auf ihrem Mantel 15 Erhebungen 13 auf, die z. B. rhombenförmig ausgebildet sein können (in Fig. 2 ausschnittsweise dargestellt). Die Gummiwalze 12 ist in einem solchen Abstand a zur Rasterwalze 1 angeordnet, daß diese bei Drehung der Rasterwalze 1 durch Reibung angetrieben werden kann, wobei sich zwischen der Rasterwalze 1 sowie der Gummiwalze 12 ein auf die Rasterwalze 1 zu übertragender Film von Druckfarbe befindet. Die Gummiwalze 12 kann auch separat durch eine nichtdargestellte Antriebseinheit, z. B. einen Elektromotor, angetrieben werden. Am Boden 14 der Farbwanne 3, d. h. in einem geringen Abstand zu diesem sowie in einem Abstand b zum Mantel 15 der Gummiwalze 12 sind mehrere, z. B. zwei in achsparalleler Richtung nebeneinander befindliche angetriebene Scheiben 17; 18 angeordnet, deren Antriebswellen 19; 21 rechtwinklig zur Rotationsachse 22 verlaufen und zu außerhalb der Kammerrakeleinrichtung 2 befindlichen, nichtdargestellten Antrieben führen können. Die Antriebe können z. B. außen am Boden 14 der Farbwanne 3 angeflanscht sein. Der Abstand b der Scheiben 17; 18 zur Gummiwalze 12 ist für jede Scheibe 17; 18 einzeln einstellbar. Es ist aber auch möglich, daß der Abstand b der Scheiben 17; 18 zur Gummiwalze 12 für beide Scheiben 17; 18 gemeinsam einstellbar ist. Die Kammerrakeleinrichtung 2 weist zwei in einem Abstand zueinander angeordnete, an die Gummiwalze 12 anstellbare federnde Rakelblätter - eine Arbeitsrakel 23 sowie eine Schließrakel 24 - auf, die sich in achsparalleler Richtung zur Rasterwalze 1 erstrecken und in leistenförmigen Haltern 26; 27 festgeklemmt sind. Die Halter 26; 27 für die Rakel 23; 24 sind beidendig formschlüssig mit den Schließblechen 4; 6 der Kammerrakeleinrichtung 2 verbunden. Die antreibbaren Scheiben 17; 18 sind zweckmäßigerweise kreisrund ausgebildet und können an ihrer Peripherie eine Verzahnung aufweisen. Weiterhin können die Scheiben 17; 18 mit verschiedenen Durchgangslöchern versehen sein, um z. B. Luftansammlungen zwischen der bodennahen Seite der Scheiben 17; 18 sowie dem Boden 14 der Farbwanne 3 zu vermeiden. Die Kammerrakeleinrichtung 2 ist durch eine angedeutete bekannte Hub- und Senkeinrichtung 28 höhenverstellbar und somit an die Rasterwalze 1 anstellbar. Eine linke obere Seitenwand (Fig. 1) der Farbwanne 3 ist schwenkbar ausgebildet, so daß in abgeschwenktem Zustand der Seitenwand Druckfarbe in die Farbwanne 3 ein- bzw. nachgefüllt werden kann.On an anilox roller 1 of a short inking unit is one a total of 2 chambered doctor blade device employable. The chambered doctor device 2 can consist of a Ink tray 3 with an approximately U-shaped profile, which is with a length l below and axially parallel extends to anilox roller 1. The length l of the paint tray 3 can be a quarter of the total length of the anilox roller 1 amount so that four different paint pans 3 under the anilox roller 1 can be arranged. Any paint tray 3 has front locking plates 4, 6, which the U-profile on both sides z. B. by means of screws close. The striking plates 4; 6 are with their the Anilox roller 1 facing the periphery of the Anilox roller 1 adapted. On both striking plates 4; 6 are in the axis-parallel direction to the anilox roller 1 and inside the chambered doctor blade device 2 Journal 7; 8 attached, on which via ball bearings 9; 11 both ends of a roller, e.g. B. rubber roller 12 is rotatably mounted. The rubber roller 12 has her coat 15 surveys 13, the z. B. can be rhomboidal (in FIG. 2 shown in sections). The rubber roller 12 is in such a distance a from the anilox roller 1, that this by rotation of the anilox roller 1 by friction can be driven, being between the Anilox roller 1 and the rubber roller 12 on the Anilox roller 1 film of printing ink to be transferred located. The rubber roller 12 can also be separated by a Drive unit not shown, e.g. B. one Electric motor to be driven. At the bottom 14 of the Paint tray 3, d. H. at a short distance from this and at a distance b from the jacket 15 of the rubber roller 12 are several, e.g. B. two in the axis-parallel direction driven disks 17; 18th arranged, the drive shafts 19; 21 perpendicular to Rotation axis 22 run and to outside of Chambered doctor blade device 2, drives not shown. The drives can e.g. B. outside on the bottom 14 of the paint tray 3 be flanged. The distance b between the disks 17; 18 to Rubber roller 12 is for each disc 17; 18 individually adjustable. But it is also possible that the distance b the disks 17; 18 to the rubber roller 12 for both disks 17; 18 is adjustable together. The Chamber doctor device 2 has two at a distance arranged to each other, adjustable to the rubber roller 12 resilient squeegee blades - a working squeegee 23 and one Closing doctor blade 24 - on, which is in axially parallel Extend towards anilox roller 1 and in strip-shaped holders 26; 27 are clamped. The Holder 26; 27 for the squeegee 23; 24 are both ends form-fitting with the striking plates 4; 6 of Chamber doctor device 2 connected. The drivable Discs 17; 18 are expediently circular trained and can at their periphery Have teeth. Furthermore, the disks 17; 18 to be provided with different through holes in order e.g. B. Air accumulations between the near-ground side of the Discs 17; 18 and the bottom 14 of the ink tray 3 avoid. The doctor blade device 2 is by a Known known lifting and lowering device 28 height adjustable and thus to the anilox roller 1 employable. A left upper side wall (Fig. 1) of the Ink tray 3 is pivotable, so that in pivoted state of the side wall printing ink in the Ink tray 3 can be filled or refilled.

Die Funktion der Kammerrakeleinrichtung 2 ist wie folgt: während des Betriebszustandes, d. h. während der Drehung der Rasterwalze 1, z. B. im Uhrzeigersinn (Fig. 1) dreht sich die Gummiwalze 12 mitläufig im Gegenuhrzeigersinn, wobei sich die Scheiben 17; 18 so drehen, daß in einem Spalt 29 zwischen beiden Scheiben 17; 18 ein Strom von Druckfarbe 20 in Richtung der Längsseite der Farbwanne 3 gefördert wird, welche die Schließrakel 24 aufweist, so daß die Gummiwalze 12 die Druckfarbe wieder in Richtung Rasterwalze 1, und die Rasterwalze 1 die Druckfarbe 20 in Richtung Arbeitsrakel 23 transportiert. In einer vergrößerten Darstellung sind die Drehrichtungen der Scheiben 17; 18 sowie der Gummiwalze 12 mittels Kreisen mit einem Punkt dargestellt, wobei das Kreis-Punkt-Zeichen 30 bedeutet, daß sich dieser so gekennzeichnete Teil aus der Ebene des Zeichnungsblattes in Richtung des Betrachters der Zeichnung herausbewegt.The function of the doctor blade device 2 is as follows: during the operating state, d. H. during the rotation the anilox roller 1, z. B. rotates clockwise (Fig. 1) the rubber roller 12 rotates counterclockwise, the disks 17; 18 turn so that in one Gap 29 between the two disks 17; 18 a stream of Ink 20 in the direction of the long side of the ink tray 3 is promoted, which has the closing doctor blade 24, so that the rubber roller 12 the ink back in the direction Anilox roller 1, and anilox roller 1 the printing ink 20 transported in the direction of the doctor blade 23. In a enlarged directions are the directions of rotation Discs 17; 18 and the rubber roller 12 by means of circles shown with a dot, the Circle dot sign 30 means that this is so marked part from the level of the drawing sheet moved out towards the viewer of the drawing.

Es wäre durchaus auch möglich, daß sich die Gummiwalze 12 gegenläufig zur Rasterwalze 1 bewegt, d. h. im Uhrzeigersinn, so daß sich an der Rasterwalze 1 zwischen der Arbeitsrakel 23 und der rasterwalzennahen Mantellinie der Gummiwalze 12 ein Farbwulst bildet.It would also be quite possible that the rubber roller 12 moved in the opposite direction to the anilox roller 1, d. H. in the Clockwise, so that on the anilox roller 1 between the working squeegee 23 and the anilox roller near Surface line of the rubber roller 12 forms an ink bead.

Nach einem anderen, nichtdargestellten Ausführungsbeispiel können beide Scheiben 17; 18 als miteinander kämmende Zahnräder ausgeführt sein, die dann auch nur einen gemeinsamen Antrieb benötigen.Another, not shown Embodiment can both discs 17; 18 as intermeshing gears are designed, which then need only a common drive.

Nach einem weiteren Ausführungsbeispiel (Fig. 3) ist es möglich, zwischen beiden als Zahnräder ausgeführten Scheiben 17; 18 eine in Nähe des Bodens 14 und innerhalb der Farbwanne 3 gelagerte und außerhalb der Farbwanne 3 angetriebene Schneckenwelle 31 anzuordnen, welche sowohl mit beiden Zahnrädern 17; 18 als auch mit einer am Umfang der Gummiwalze 12 befindlichen Verzahnung 32 kämmt. Die Verzahnung 32 der Gummiwalze 12 befindet sich an der Stelle der Hälfte der Länge l der Farbwanne 3 und ragt nicht über die Mantelfläche 15 der Gummiwalze 12 heraus. Es ergibt sich die vorgenannte Bewegungsrichtung der Teile 17; 18; 32 (Fig. 3).According to a further embodiment (Fig. 3) it is possible between the two designed as gears Discs 17; 18 one near the bottom 14 and inside the paint tray 3 stored and outside the paint tray 3 to arrange driven worm shaft 31, which both with both gears 17; 18 as well as with a Scope of the rubber roller 12 located teeth 32nd combs. The toothing 32 of the rubber roller 12 is located at the point of half the length l of the ink tray 3 and does not protrude over the outer surface 15 of the rubber roller 12 out. The above-mentioned direction of movement results of parts 17; 18; 32 (Fig. 3).

Es ist auch möglich, nur eine antreibbare Scheibe 18 oder 19 im Boden 14 der Farbwanne 3 anzuordnen. Die Farbwanne 3 ist, wie insbesondere aus Fig. 1 ersichtlich, senkrecht unter einer Rotationsachse 16 der Rasterwalze 1 angeordnet. Es ist jedoch auch möglich, daß eine durch die Rotationsachse 16 der Rasterwalze 1 verlaufende senkrechte Mittellinie 25 der Farbwanne 3 um einen Winkel plus oder minus Alpha geschwenkt wird, so daß die Farbwanne 3 seitlich an der Rasterwalze anliegt. It is also possible to have only one drivable disk 18 or 19 in the bottom 14 of the ink tray 3 to be arranged. The Ink tray 3 is, as in particular from FIG. 1 can be seen perpendicular to an axis of rotation 16 of the Anilox roller 1 arranged. However, it is also possible that one through the axis of rotation 16 of the anilox roller 1 running vertical center line 25 of the ink tray 3 um panning an angle plus or minus alpha, so that the ink tray 3 rests laterally on the anilox roller.

Dabei würde dann die antreibbare Scheibe 17; 18 nur teilweise in die Druckfarbe 20 eintauchen.Then the drivable disk 17; 18 only partially immerse in ink 20.

Der Winkel Alpha kann zwischen Null und 45° liegen. Eine Füllhöhe h der Druckfarbe 20 kann zwischen einem Viertel bis zur Hälfte des Durchmessers der Walze 12 betragen. The angle alpha can be between zero and 45 °. A Filling height h of the printing ink 20 can be between a quarter be up to half the diameter of the roller 12.
