Description

Die Erfindung betrifft ein Farbwerk für Rotationsdruckmaschinen, bei welchem die Farbe von einer Farbkastenwalze über einen nachgeschalteten Farbtransportstrang, der aus einer veränderbaren Zahl von in Farbtransportrichtung in Reihe hintereinander angeordneten Farbwerkswalzen besteht, mindestens einer Auftragwalze zuführbar ist.The invention relates to an inking unit for rotary printing presses, in which the ink can be fed from at least one applicator roller from an ink fountain roller via a downstream ink transport line which consists of a variable number of inking unit rollers arranged in series in the ink transport direction.

Ein Farbwerk dieser Gattung ist aus der US-A-2 158 474 bekannt. Bei diesem Farbwerk kann eine Heberwalze die Farbe wahlweise von der mit geringer Geschwindigkeit umlaufenden Farbkastenwalze oder von einer an die Farbkastenwalze anstellbaren Zusatzwalze abnehmen und dann den weiteren Farbwerkswalzen zuleiten. Die Zusatzwalze soll vorzugsweise schneller als die Farbkastenwalze umlaufen, um zwischen diesen beiden Walzen eine Farbverreibung zu erreichen, die unaufgelöste Farbpartikel beseitigen soll. Die Geschwindigkeitsdifferenz zwischen der Farbkastenwalze und der Heberwalze führt auch dazu, daß die Farbschicht auf der Zusatzwalze dünner ist als auf der Farbkastenwalze. Die Heberwalze nimmt zwar von der Farbkastenwalze einen dickeren Farbfilm ab als von der Zusatzwalze, die Farbkastenwalze läuft jedoch mit geringerer Geschwindigkeiten um als die Zusatzwalze. Auch ist die Anlagezeit der Heberwalze an der Farbkastenwalze wegen des längeren Schwenkweges eher kürzer als die Anlagezeit an der Zusatzwalze. Von der Farbkastenwalze wird daher ein dickerer Farbstreifen abgenommen, der jedoch kürzer ist als der dünnere Farbstreifen, der von der Zusatzwalze abgenommen wird. Somit wird die verminderte Dicke des von der Zusatzwalze abgenommenen Farbstreifens durch dessen größere Länge ausgeglichen. Die Heberwalze führt daher bei beiden Einstellungen etwa die gleiche Farbmenge zu den nachgeschalteten Farbwerkswalzen.An inking unit of this type is known from US-A-2 158 474. With this inking unit, a siphon roller can either remove the ink from the ink fountain roller rotating at low speed or from an additional roller that can be adjusted to the ink fountain roller and then feed it to the other inking roller. The additional roller should preferably rotate faster than the ink fountain roller in order to achieve ink rubbing between these two rollers, which is intended to eliminate undissolved ink particles. The speed difference between the ink fountain roller and the lifter roller also means that the ink layer on the additional roller is thinner than on the ink fountain roller. Although the siphon roller removes a thicker ink film from the ink fountain roller than from the additional roller, the ink fountain roller rotates at lower speeds than the additional roller. Also, the time it takes for the lifter roller to attach to the ink fountain roller is shorter than the time it takes for the additional roller to move. A thicker ink strip is therefore removed from the ink fountain roller, but this is shorter than the thinner ink strip that is removed from the additional roller. Thus, the reduced thickness of the ink strip removed from the additional roller is compensated for by its longer length. The lifter roller therefore supplies approximately the same amount of ink to the downstream inking unit rollers in both settings.

Der Erfindung liegt die Aufgabe zugrunde, ein derartiges Farbwerk so weiterzubilden, daß eine Änderung des Dickenbereiches des an den Plattenzylinder abzugebenden Farbfilmes ohne Änderung der Farbmessereinstellung erreichbar ist. Die Forderung nach einer Veränderbarkeit der Dicke des von einem Farbwerk gelieferten Farbfilmes tritt insbesondere bei Farbwerken auf, die sowohl für Offsetdruck als auch für Dilitho-Druck verwendet werden sollen. Während bei Offsetdruck eine sehr dünne Farbschicht erwünscht und brauchbar ist, benötigt der Dilitho-Druck dann eine dickere Farbschicht, wenn Papiere bedruckt werden sollen, die keine glatte Oberfläche haben. Infolge des Entfalls des nachgiebigen Gummituches und des Druckes direkt von der harten Platte besteht hier der Nachteil, daß dünne Farbschichten nicht in alle Vertiefungen der Papieroberfläche gelangen, so daß das Sujet nicht vollständig ausgedruckt wird.The invention has for its object to develop such an inking unit so that a change in the thickness range of the ink film to be delivered to the plate cylinder can be achieved without changing the ink knife setting. The requirement for the thickness of the ink film supplied by an inking unit to be changeable arises in particular in inking units which are to be used both for offset printing and for dilitho printing. While a very thin layer of ink is desirable and usable in offset printing, dilitho printing requires a thicker layer of ink when printing papers that do not have a smooth surface. As a result of the elimination of the flexible rubber blanket and the printing directly from the hard plate, there is the disadvantage that thin layers of color do not reach all the depressions in the paper surface, so that the subject is not printed out completely.

Die gestellte Aufgabe wird durch Anwendung der Merkmale des Kennzeichens des Anspruches gelöst.The object is achieved by applying the features of the characterizing part of the claim.

Weitere Merkmale und Vorteile ergeben sich aus den Unteransprüchen in Verbindung mit der Beschreibung eines Ausführungsbeispieles der Erfindung anhand der Zeichnung. In dieser zeigt :

  • Figur 1 ein erfindungsgemäßes Farbwerk in der Einstellung auf geringe Farbschichtdicken und
  • Figur 2 das gleiche Farbwerk in der Einstellung auf größere Farbschichtdicken.
Further features and advantages result from the subclaims in connection with the description of an embodiment of the invention with reference to the drawing. In this shows:
  • 1 shows an inking unit according to the invention in the setting for small ink layer thicknesses and
  • Figure 2 shows the same inking unit in the setting for larger ink layer thicknesses.

Das dargestellte Farbwerk umfaßt eine mit geringer Oberflächengeschwindigkeit angetriebene Farbkastenwalze 1, an die ein Farbmesser 2 mehr oder minder stark anstellbar ist. Von der Farbkastenwalze 1 wird die Farbe in der Einstellung nach Fig. 2 über fünf Farbwerkswalzen 3 bis 7 auf zwei Auftragwalzen 8, 9 übertragen, die ihrerseits die Farbe an eine Platte auf einem Plattenzylinder 10 abgeben. Zweckmäßig weisen die Farbwerkswalzen 3, 5 und 7 eine metallische, harte Oberfläche auf und sind als Reiber ausgebildet, also in Längsrichtung changierend angeordnet.The inking unit shown comprises an ink fountain roller 1 driven at low surface speed, against which an ink knife 2 can be adjusted more or less strongly. The ink in the setting according to FIG. 2 is transferred from the ink fountain roller 1 via five inking rollers 3 to 7 to two applicator rollers 8, 9, which in turn deliver the ink to a plate on a plate cylinder 10. The inking rollers 3, 5 and 7 expediently have a metallic, hard surface and are designed as a grater, that is to say they are arranged so as to change in the longitudinal direction.

Vor den beiden Enden der an nicht dargestellten Farbwerksseitenwänden gelagerten Farbwerkswalzen 3 und 7 sind um mit ihren Achsen fluchtende Achszapfen 11, 12 schwenkbare Hebel 13, 14 gelagert, zwischen deren anderen Enden die Farbwerkswalzen 4 und 6 mit ihren Achszapfen 15, 16 drehbar gelagert sind. Zweckmäßig sind weiterhin die Farbwerkswalzen 3, 5 und 7 angetrieben, und zwar mit der gleichen Oberflächengeschwindigkeit wie der Plattenzylinder 10, während die Farbwerkswalzen 4 und 6 sowie die Auftragwalzen 8 und 9 durch Reibung mitgenommen werden. Zur Betätigung der Hebel 13,14 dienen Hydraulikzylinder 17, 18 mit Stellstangen 19, 20, die an den Hebeln 13, 14 angelenkt sind.In front of the two ends of the inking unit rollers 3 and 7 mounted on inking device side walls (not shown), levers 13, 14 which are pivotable about axles aligned with their axes are mounted, between the other ends of which the inking unit rollers 4 and 6 are rotatably mounted with their axle journals 15, 16. The inking unit rollers 3, 5 and 7 are also expediently driven, at the same surface speed as the plate cylinder 10, while the inking unit rollers 4 and 6 and the application rollers 8 and 9 are carried along by friction. Hydraulic cylinders 17, 18 with adjusting rods 19, 20, which are articulated on the levers 13, 14, are used to actuate the levers 13, 14.

Weiterhin sind zwei ebenfalls an den Farbwerksseitenwänden gelagerte Zusatzfarbwerkswalzen 21, 22 vorgesehen, an die, wie Fig. 1 zeigt, die Farbwerkswalzen 4 bzw. 6 angeschwenkt werden können. Vor den beiden Enden der Zusatzfarbwerkswalzen 21, 22 sind mittels Achszapfen 23, 24, die mit den Achsen der Zusatzfarbwerkswalzen 21, 22 fluchten, Hebel 25, 26 schwenkbar gelagert. An den Hebeln 25 sind Achszapfen 27 einer weiteren Zusatzfarbwerkswalze 28 drehbar gelagert, während die Hebel 26 zur Lagerung der Achszapfen 29 einer Zusatzfarbwerkswalze 30 dienen. Die Hebel 25, 26 sind wiederum mittels Hydraulikzylindern 31, 32 und Stellstangen 33, 34 schwenkbar.Furthermore, two additional inking unit rollers 21, 22, also mounted on the inking unit side walls, are provided, to which, as shown in FIG. 1, the inking unit rollers 4 and 6 can be pivoted. In front of the two ends of the additional inking unit rollers 21, 22, levers 25, 26 are pivotably mounted by means of axle journals 23, 24, which are aligned with the axes of the additional inking unit rollers 21, 22. Axle journals 27 of a further additional inking unit roller 28 are rotatably mounted on the levers 25, while the levers 26 serve to support the axle journals 29 of an additional inking unit roller 30. The levers 25, 26 are in turn pivotable by means of hydraulic cylinders 31, 32 and adjusting rods 33, 34.

In der in Fig. 2 wiedergegebenen Anordnung der Teile wird die Farbe über die durch den strichpunktierten Linienzug A miteinander verbundenen Farbwerkswalzen 3 bis 7 zu den Auftragwalzen 8 und 9 geführt. In dieser ersten Einstellung wird den Auftragwalzen 8, 9 ein verhältnismäßig dicker Farbfilm zugeführt. Das Farbwerk kann daher in dieser Einstellung für Dilitho-Druck Verwendung finden. Diese Einstellung kann aber auch bei Offsetdruck verwendet werden, wenn große zusammenhängende Flächen bedruckt werden sollen.In the arrangement of the parts shown in FIG. 2, the ink is guided to the applicator rollers 8 and 9 via the inking unit rollers 3 to 7 which are connected to one another by the dash-dot line A. In this first setting, the application rollers 8, 9 are fed a relatively thick ink film. The inking unit can therefore be used in this setting for dilitho printing. This setting can also be used for offset printing when large contiguous areas are to be printed.

Wird dagegen ein dünnerer Farbfilm auf den Auftragwalzen 8, 9 gewünscht, so werden die Hydraulikzylinder 17, 18, 31, 32 betätigt. Hierdurch wird die Farbwerkswalze 6 von der Farbwerkswalze 5 abgehoben, so daß zwischen diesen beiden Walzen ein Spalt entsteht und gleichzeitig zur Anlage an der Zusatzfarbwerkswalze 22 gebracht. In gleicher Weise wird die Farbwerkswalze 4 von der Farbwerkswalze 5 abgehoben und zur Anlage an der Zusatzfarbwerkswalze 21 gebracht, so daß auch zwischen den Walzen 4 und 5 wiederum ein Spalt entsteht. Die beiden so entstandenen Spalte werden dadurch überbrückt, daß die Zusatzfarbwerkswalzen 28 und 30 so weit um die Walzen 21, 22 geschwenkt werden, daß sie zur Anlage an der Farbwerkswalze 5 kommen. Nunmehr ergibt sich der in Fig. 1 durch die strichpunktierte Linie B angedeutete längere Farbtransportweg. Bei dieser zweite Einstellung wird jeder Spalt zwischen den Farbwerkswalzen 4, 5 bzw. 5, 6 durch zwei Zusatzfarbwerkswalzen überbrückt. Es kann daher auch beim längeren Farbtransportweg abwechselnd eine Walze mit einer harten Oberfläche und eine Walze mit einer weichen Oberfläche vorgesehen werden.If, on the other hand, a thinner ink film is desired on the application rollers 8, 9, the hydraulic cylinders 17, 18, 31, 32 are actuated. As a result, the inking roller 6 is lifted from the inking roller 5, so that a gap is formed between these two rollers and at the same time brought to bear on the additional inking roller 22. In the same way, the inking roller 4 is lifted from the inking roller 5 and brought into contact with the additional inking roller 21, so that again a gap is formed between the rollers 4 and 5. The two gaps thus created are bridged in that the additional inking unit rollers 28 and 30 are pivoted so far about the rollers 21, 22 that they come to rest on the inking unit roller 5. Now there is the longer ink transport path indicated by the dash-dotted line B in FIG. 1. With this second setting, each gap between the inking rollers 4, 5 and 5, 6 is bridged by two additional inking rollers. A roller with a hard surface and a roller with a soft surface can therefore be alternately provided even with the longer ink transport path.

Bei Anwendung der Erfindung wird durch Ein-oder Auschalten der Zusatzfarbwerkswalzen 21, 22, 28, 30 zunächst ohne Einstellung des Farbmessers 2 eine Änderung der Farbfilmdicke an den Auftragwalzen 8, 9 erreicht. Das Farbmesser 2 dient somit lediglich zur Feineinstellung der Farbfilmdicke innerhalb des durch die Veränderung der Zahl der Walzen des Farbtransportstranges voreingestellten Dickenbereiches. Es kann somit verhindert werden, daß der Drucker versucht, das Farbmesser 2 so weit zu öffnen, daß die Farbfilmdicke an der mit größerer Geschwindigkeit umlaufenden Farbwerkswalze 3 so groß wird, daß die Farbe abspritzt.When the invention is applied, switching the additional inking unit rollers 21, 22, 28, 30 on or off initially changes the ink film thickness on the application rollers 8, 9 without adjusting the ink knife 2. The ink knife 2 is therefore only used for fine adjustment of the ink film thickness within the thickness range preset by changing the number of rollers of the ink transport strand. It can thus be prevented that the printer tries to open the ink knife 2 to such an extent that the ink film thickness on the inking roller 3 rotating at a higher speed becomes so great that the ink squirts off.

Bei der beim Ausführungsbeispiel gezeigten Abstellbarkeit der Farbwerkswalzen 4 und 6 von der Farbwerkswalze 5 besteht weiterhin die Möglichkeit, eine Zwischenstellung für eine mittlere Farbfilmdicke einzustellen, beispielsweise dadurch, daß die Farbwerkswalze 6 und die Zusatzfarbwerkswalze 30 die in Fig. 1 angegebene Stellung einnehmen, während die Farbwerkswalze 4 und die Zusatzfarbwerkswalze 28 in der in Fig. 2 dargestellten Lage belassen werden. Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt. Anstelle der Unterbrechung des kurzen Farbtransportstranges an zwei Stellen kann dieser auch an einer oder drei Stellen unterbrochen werden. Weiterhin besteht die Möglichkeit, zur Überbrükkung der Unterbrechungsstellen des kurzen Farbtransportstranges auch entweder eine oder mehr als zwei Walzen einzuschalten, die dann in Reihe hintereinander anzuordnen sind.In the case of the fact that the inking unit rollers 4 and 6 can be switched off from the inking unit roller 5 as shown in the exemplary embodiment, there is also the possibility of setting an intermediate position for a medium ink film thickness, for example by virtue of the fact that the inking unit roller 6 and the additional inking unit roller 30 assume the position shown in FIG. 1 while the Inking roller 4 and the additional inking roller 28 are left in the position shown in Fig. 2. The invention is not restricted to the exemplary embodiment shown. Instead of interrupting the short ink transport strand at two points, it can also be interrupted at one or three points. There is also the possibility of switching on either one or more than two rollers, which are then to be arranged in series, in order to bridge the interruption points of the short ink transport strand.
