Description

Die Erfindung betrifft ein Spülfarbwerk für eine Rotationsdruckmaschine mit einem an die Farbauftragswalze anstellbaren Rakelmesser, das an einer um eine zur Farbauftragswalzenachse parallele und oberhalb von dieser angeordneten _ Achse schwenkbaren Rakelmesserhalterung befestigt und durch eine auf die Rakelmesserhalterung wirkende Druckmittel-Kolben-Zylinder-Einheit an die Farbauftragswalze anstellbar ist, mit einer zwischen dem Rakelmesser, der Rakelmesserhalterung und der Farbauftragswalze gebildeten Farbverteilungsrinne, mit einer die Farbe zuführenden Leitung und einer die aus der Farbverteilungsrinne ablaufende Farbe auffangenden Wanne.The invention relates to a rinsing inking unit for a rotary printing press with a doctor blade which can be adjusted to the inking roller, which is attached to a doctor blade holder which can be pivoted about an axis parallel to the inking roller axis and which is arranged above it, and to the doctor blade cylinder unit which acts on the doctor blade holder Ink application roller is adjustable, with an ink distribution channel formed between the doctor blade, the doctor blade holder and the ink application roller, with a line supplying the ink and a trough collecting the ink flowing out of the ink distribution channel.

Bei einem aus der DE-AS 18 06 140 bekannten Spülfarbwerk dieser Art ist die Rakelmesserhalterung an einem stützenden Träger befestigt, der um Zapfen schwenkbar an einem gestellfesten Sammelrohr gelagert ist. An dem Sammelrohr sind hydraulische Ausstellvorrichtungen befestigt, die sich mit ihren Betätigungsstößeln auf dem Träger abstützen und über diesen das Rakelmesser an die Farbauftragswalze andrücken.In a flushing inking unit of this type known from DE-AS 18 06 140, the doctor blade holder is fastened to a supporting support which is pivotably mounted on a collecting tube fixed to the frame. Hydraulic Ausstellvorrichtungen are fixed to the collecting pipe, which are supported with their actuating tappets on the support and by the press on the doctor blade to the F arbauftragswalze.

Bei der bekannten Vorrichtung muß die hydraulische Anstellvorrichtung die gesamte das Rakelmesser andrückende Kraft aufbringen. Aufgabe der Erfindung ist es daher, das bekannte Spülfarbwerk dadurch zu verbessern, daß zur feinfühligen Anstellung des Rakelmessers von der Druckmittel-Kolben-Zylinder-einheit nur geringe oder überhaupt keine Anstellkräfte aufgebracht werden müssen.In the known device, the hydraulic adjusting device must exert the entire force pressing on the doctor blade. The object of the invention is therefore to improve the known S pülfarbwerk in that little or no contact forces have to be applied by the pressure medium piston-cylinder unit for sensitive adjustment of the doctor blade.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Farbverteilungsrinne durch ein zweites an der Rakelmesserhalterung befestigtes und an die Farbauftragswalze anstellbares Rakelmesser geschlossen und die die Rakelmesserhalterung bildende Leiste pendelartig an einer Welle derart befestigt ist, daß sich die Rakelmesser seitlich auf dem Mantel der Farbauftragswalze abstützen.According to the invention this object is achieved in that the F arbverteilungsrinne closed akelmesser by a second fixed to the doctor blade holder and Unemployable to the inking roller R and the doctor blade holder forming strip is pendulously mounted on a shaft such that the doctor blades laterally on the jacket of the inking roller support.

Der Aufbau des erfindungsgemäßen Spülfarbwerks und dessen Handhabung sind gegenüber bekannten Vorrichtungen wesentlich vereinfacht.The structure of the flushing inking unit according to the invention and its handling are considerably simplified compared to known devices.

zweckmäßigerweise besteht ein Rakelmesser aus elastischerem Material als das andere, damit auch dann eine gute Anlage der Rakelmesser an der Rasterwalze gewährleistet ist, wenn die Rakelmesser nicht genau zu dieser ausgerichtet sind. Durch seine größere Elastizität und Biegeweichheit gleicht das elastischere Rakelmesser eventuelle Fehlstellungen der Farbauftragsleiste aus.advantageously, there is a doctor blade made of a more elastic material than the other, so that a good contact of the R akelmesser ensured on the anilox roll when the doctor blades are not aligned exactly to this. Due to its greater elasticity and flexural softness the more elastic doctor blade any F resembles ehlstellungen the inking bar.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben worden.Advantageous embodiments of the invention have been described in the subclaims.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. In dieser zeigt

  • Fig. 1 eine Draufsicht auf die Farbauftragswalze sowie die das Spülfarbwerk tragende Welle, allerdings ohne das Spülfarbwerk selbst,
  • Fig. 2 einen Schnitt durch die Vorrichtung nach Fig. 1 längs der Linie II - II mit an der Welle befestigtem Spülfarbwerk und
  • .Fig. 3 einen Schnitt durch die Vorrichtung längs der Linie III - III in Fig. 1.
An embodiment of the invention is explained below with reference to the drawing. In this shows
  • 1 is a plan view of the inking roller and the shaft carrying the flushing inking unit, but without the flushing inking unit itself,
  • Fig. 2 shows a section through the device of FIG. 1 along the line II - II with flushing inking unit attached to the shaft and
  • . 3 shows a section through the device along the line III-III in FIG. 1.

Die die Farbauftragswalze bildende Rasterwalze 1 ist in Farbwerksböcken 2, 3 gelagert. Auf den Farbwerksböcken 2 und 3 sind Trägerplatten 4, 5 aufgeschraubt, auf denen Lagerböcke 6, 7 befestigt sind. In den Lagerböcken 6, 7 ist eine Welle 8 drehbar und längsverschieblich gelagert, die in dem zwischen den Lagerböcken 6, 7 liegenden Abschnitt quadratisch ausgebildet ist. Die Käfige 6, 7 der Kugelumlauflagerung für die Welle 8 erstrecken sich über die Breite der Lagerböcke 6, 7 hinaus. Nach rechts ist.die Welle 8 verlängert.The anilox roller 1 forming the inking roller is mounted in inking units 2, 3. Carrier plates 4, 5 are screwed onto the inking blocks 2 and 3, on which bearing blocks 6, 7 are fastened. In the bearing blocks 6, 7, a shaft 8 is rotatably and longitudinally displaceably, which is square in the section lying between the bearing blocks 6, 7. The cages 6, 7 of the recirculating ball bearing for the shaft 8 extend beyond the width of the bearing blocks 6, 7. The wave 8 is extended to the right.

Auf dem überstehenden Teil der Welle 8 ist ein Führungsstück 12 drehbar gelagert, jedoch durch einen in die Welle 8 eingreifenden Sicherungsring 13 gegen Längsverschiebung auf der Welle 8 gesichert. Das Führungsstück 12 weist eine Gabel 14 auf, in die ein Kugellager 15 eingepaßt ist, dessen Innenring mittels eines Bolzens 16 im Lagerbock 7 befestigt ist. Durch diese Anordnung wird das Führungsstück 12 gegenüber der Welle 8 an einer Drehung gehindert, die Bewegung, d. h. die Rakelbewegung, in Richtung der Längserstreckung der Welle 8 ist jedoch ermöglicht. Diese Rakelbewegung wird durch einen Elektromotor 17 erzeugt, der an einem am Farbwerksbock 3 befestigten Lagergehäuse 18 angeschraubt ist. Im Lagergehäuse 18 ist eine Welle 19 drehbar gelagert, in die der Antriebszapfen 20 des Elektromotors 17 eingreift. Auf der Welle 19 ist ein Innenring eines Kugellagers 21 exzentrisch befestigt, dessen Außenring in eine Nut 22 eingepaßt ist, die in einer Platte 23 eingearbeitet ist. Die Platte 23 ist am Führungsstück 12 befestigt, so daß die exzentrische Bewegung des Kugellagers 21 auf die Welle 8 als hin- und hergehende Bewegung übertragen wird.On the protruding part of the shaft 8, a guide piece 12 is rotatably supported, but is secured against longitudinal displacement on the shaft 8 by a locking ring 13 engaging in the shaft 8. The guide piece 12 has a fork 14 into which a ball bearing 15 is fitted, the inner ring of which is fastened in the bearing block 7 by means of a bolt 16. This arrangement prevents the guide piece 12 from rotating with respect to the shaft 8, the movement, ie the squeegee movement, in the direction of the longitudinal extent of the Wave 8 is however possible. This squeegee movement is generated by an electric motor 17 which is screwed to a bearing housing 18 fastened to the inking unit 3. In the bearing housing 18, a shaft 19 is rotatably mounted, in which the drive pin 20 of the electric motor 17 engages. On the shaft 19, an inner ring of a ball bearing 21 is fastened eccentrically, the outer ring of which is fitted into a groove 22 which is incorporated in a plate 23. The plate 23 is attached to the guide piece 12 so that the eccentric movement of the ball bearing 21 is transmitted to the shaft 8 as a reciprocating movement.

Auf dem überstehenden Teil der Welle 8 ist schließlich ein Hebel 25 festgeklemmt, dessen freies Ende mit der Kolbenstange eines Pneumatikzylinders 26 gelenkig verbunden ist.. Am Pneumatikzylinder 26 sind Ohren 27 vorgesehen, die mit einer an der Platte 23 angearbeiteten Gabel 28 gelenkig verbunden sind, so daß sich der Pneumatikzylinder 26 bei Betätigung frei bewegen kann. Durch den Pneumatikzylinder 26 kann die Welle 8 um ihre Längsachse geschwenkt werden und dadurch an die Rasterwalze 1 angedrückt oder von ihr abgehoben werden.Finally, on the protruding part of the shaft 8, a lever 25 is clamped, the free end of which is articulated to the piston rod of a pneumatic cylinder 26. Ears 27 are provided on the pneumatic cylinder 26, which are articulated to a fork 28 worked on the plate 23, so that the pneumatic cylinder 26 can move freely when actuated. By means of the pneumatic cylinder 26, the shaft 8 can be pivoted about its longitudinal axis and thereby pressed against the anilox roller 1 or raised from it.

Am mit quadratischem Querschnitt ausgebildeten, zwischen den Lagerböcken 6, 7 liegenden Teil der Welle 8 ist eine an ihrem Ende verstärkte Leiste 30 befestigt, an die eine Farbauftragsleiste 31 mit Hilfe zweier gleichmäßig auf der Länge der Farbauftragsleiste 31verteilter Knebelschrauben 32 angeschraubt ist. Die Knebelschrauben greifen durch etwas größer ausgebildete Durchgangslöcher in der Leiste 30 hindurch, so daß sich die Farbauftragsleiste 31 in begrenztem Maß verschieben läßt.On the part of the shaft 8 which is formed with a square cross section and is located between the bearing blocks 6, 7, a bar 30 which is reinforced at its end is fastened, to which a paint application bar 31 is screwed by means of two toggle screws 32 which are evenly distributed over the length of the paint application bar 31. The toggle screws reach through somewhat larger through holes in the bar 30, so that the paint application bar 31 can be moved to a limited extent.

Im quadratischen Teil der Welle 8 sind in gehörigem Abstand voneinander justierbare Anschlagschrauben 33 vorgesehen, an die die Auftragsleiste 31 anschlagen kann, so daß sie die vorgesehene Stellung zur Rasterwalze 1 einnimmt. Bei einer Drehrichtung der Rasterwalze 1 in Richtung des Pfeils 1.1 ist an der Farbauftragsleiste 31 ein Rakelmesser 34 und ein Abstreifmesser 35 verschraubt. Daher bildet sich zwischen der Rasterwalze 1, der Farbauftragsleiste 31 und den Messern 34, 35 ein Hohlraum 36, der durch eine sich über die gesamte Länge der Farbauftragsleiste 31 erstreckende Ausnehmung vergrößert wird. Dem Hohlraum 36 führt ein Schlauch 38 über ein Rohr 39 in nicht dargestellter Weise Farbe zu. Damit die Farbe nicht sofort über die Stirnseiten abläuft, sind diese in bekannter, -jedoch nicht dargestellter Weise durch Deckbleche abgedeckt, die z. T. auch die Stirnflächen der Rasterwalzen 1 überdecken. Diese Deckbleche schließen zur Rasterwalze 1 nicht exakt ab, so daß dort Farbe und evtl. Verunreinigungen in der Farbe abfließen können, die in einem nicht dargestellten Tropfblech aufgefangen werden.In the square part of the shaft 8 adjustable stop screws 33 are provided at a suitable distance from one another, against which the application bar 31 can strike, so that it assumes the intended position relative to the anilox roller 1. When the anilox roller 1 rotates in the direction of arrow 1.1, a doctor blade 34 and a doctor blade 35 are screwed to the ink application bar 31. Therefore, a cavity 36 is formed between the anilox roller 1, the ink application bar 31 and the knives 34, 35, which is enlarged by a recess extending over the entire length of the ink application bar 31. A hose 38 feeds the cavity 36 via a tube 39 in a manner not shown. So that the color does not run off immediately on the end faces, these are covered in a known, but not shown manner by cover plates which, for. T. also cover the end faces of the anilox rollers 1. These cover plates do not close off from the anilox roller 1, so that there color and any contaminants in the paint can flow away, which are collected in a drip plate, not shown.

Der Schwerpunkt der Farbauftragsleiste 31 liegt unter der Welle 1 derart, daß sie bereits durch ihr Eigengewicht an der Rasterwalze 1 anliegt. Wenn die Farbe gewechselt werden soll, kann die Farbauftragsleiste 31 durch Betätigung des Pneumatikzylinders 26 von der Rasterwalze 1 abgehoben und nach Lösen der Schrauben 32 aus der Maschine herausgenommen werden. Durch Betätigung des Pneumatikzylinders 26 im anderen Sinn kann die Farbauftragsleiste 31 gegen die Rasterwalze 1 angedrückt werden, falls dies notwendig ist.The focus of the ink application bar 31 is under the shaft 1 such that it already bears against the anilox roller 1 by its own weight. If the color is to be changed, the ink application bar 31 can be lifted from the anilox roller 1 by actuating the pneumatic cylinder 26 and can be removed from the machine after loosening the screws 32. By actuating the pneumatic cylinder 26 in the other sense, the ink application bar 31 can be pressed against the anilox roller 1 if this is necessary.
