Description

Die Erfindung betrifft ein Farbmesser für eine Farbkastenwalze von Druckmaschinen, mit einem in einer Halterung einspannbaren Klemmbereich und einem frei auskragenden Arbeitsbereich, der durch nutartige, am Rücken des Farbmessers und von dessen Vorderkante ausgehend angeordnete Aussparungen in einzeln verstellbare, jedoch zusammenhängende Teilbereiche untergliedert ist, von denen jeder zur Einstellung einer Farbschichtdicke in einer Farbzone mittels eines Stellgliedes individuell an die Farbkastenwalze anstellbar ist.The invention relates to an ink knife for an ink fountain roller of printing presses, with a clamping area which can be clamped in a holder and a freely projecting working area which is subdivided into individually adjustable but coherent partial areas by groove-like cutouts arranged on the back of the ink knife and from its front edge each of which can be adjusted individually to the ink fountain roller for setting an ink layer thickness in an ink zone by means of an actuator.

Farbmesser mit diesen Merkmalen sind aus der DE-A-25 45 737 und der US-A-2 283 830 bekannt. In beiden Fällen ist beiderseits eines Teilbereiches des Farbmessers jeweils nur eine nutartige Aussparung angeordnet, welche Aussparungen zudem in ihrer Erstreckungsrichtung parallel zueinander verlaufen. Im Falle der DE-A besitzen die nutartigen Aussparungen einen halbkreisförmigen Querschnitt, im Falle der US-A einen rechteckigen oder alternativ hierzu einen dreieckigen Querschnitt, wobei die letztere Ausführung gemäß der US-A sich von der Vorderkante des Farbmessers ausgehend keilförmig verengt. Bei keiner dieser bekannten Lösungen ist jedoch gewährleistet, daß bei Anstellung eines Farbmesserteilbereiches an die Farbkastenwalze die benachbarten Teilbereiche und deren Funktion unbeeinflußt bleiben. Letzteres hat zur Folge, daß auch keine Farbzonen mi: definierter Breite ohne Überzeichnung des Randbereiches benachbarter Farbzonen erzielbar sind.Color meters with these features are known from DE-A-25 45 737 and US-A-2 283 830. In both cases only a groove-like recess is arranged on both sides of a partial area of the color knife, which recesses also run parallel to one another in their direction of extension. In the case of DE-A, the groove-like recesses have a semicircular cross section, in the case of US-A a rectangular or alternatively a triangular cross section, the latter embodiment narrowing in a wedge shape starting from the front edge of the color knife according to US-A. In none of these known solutions, however, it is ensured that when a part of the ink knife is placed against the ink fountain roller, the adjacent parts and their function remain unaffected. The latter has the result that no color zones mi: defined width can be achieved without overwriting the edge area of adjacent color zones.

Es ist daher Aufgabe der Erfindung, ein Farbmesser mit einer solchen Geometrie zu schaffen, die in jeder Einstellung der einzelnen Teilbereiche des Farbmessers eine definierte Farbmenge bei gleichbleibender Schichtdicke über die Breite einer Farbzone ohne Beeinflussung benachbarter Farbzonen ermöglicht.It is therefore an object of the invention to provide a color meter with such a geometry that, in each setting of the individual partial areas of the color meter, enables a defined amount of color with a constant layer thickness over the width of a color zone without influencing adjacent color zones.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß zwischen jeweils zwei benachbarten Teilbereichen des Farbmessers jeweils zwei nutartige Aussparungen vorgesehen sind, die, ausgehend von der Vorderkante des Farbmessers zum Klemmbereich desselben, V-förmig aufeinander zulaufen.This object is achieved in that two groove-like recesses are provided between each two adjacent sections of the color knife, which, starting from the front edge of the color knife to the clamping area of the same, converge in a V-shape.

Diese konstruktiv gegebene Verformbarkeit des Farbmessers 3 gewährleistet eine exakt definierte Farbmenge in jeder Farbzone ohne Beeinflussung angrenzender Farbzonen, so daß hervorragende Druckergebnisse zu erzielen sind.This structurally given deformability of the ink knife 3 ensures a precisely defined amount of ink in each ink zone without influencing adjacent ink zones, so that excellent printing results can be achieved.

Die Erfindung ist im Zusammenhang mit einem in der Zeichnung dargestellten Ausführungsbeispiel näher erläutert. In der Zeichnung zeigen :

  • Figur 1 eine schematische Darstellung eines Farbmessers in bezug auf eine Farbkastenwalze,
  • Figur 2 eine Schnittansicht des Farbmessers nach der in Fig. 1 eingetragenen Schnittlinie 11-11,
  • Figur 3 einen vergrößerten Ausschnitt des Farbmessers in Relation zur Farbkastenwalze, entsprechend Ansicht A von Fig. 1,
  • Figur 4 den gleichen Farbmesserausschnitt wie nach Fig. 3, jedoch hier mit einem an die Farbkastenwalze angestellten Teilabschnitt.
The invention is explained in connection with an embodiment shown in the drawing. The drawing shows:
  • FIG. 1 shows a schematic illustration of an ink knife in relation to an ink fountain roller,
  • FIG. 2 shows a sectional view of the color knife along the section line 11-11 shown in FIG. 1,
  • 3 shows an enlarged section of the ink knife in relation to the ink fountain roller, corresponding to view A of FIG. 1,
  • Figure 4 shows the same ink knife section as shown in Fig. 3, but here with a section of the ink fountain roller.

Bei der schematischen Darstellung nach Fig. 1 ist mit 1 ein Farbkasten, mit 2 eine Farbkastenwalze und mit 3 ein Farbmesser bezeichnet. Letzteres besitzt einen Klemmbereich 4, mit dem es in einer am Farbkasten 1 befestigten, mehrteiligen Halterung 5 eingespannt ist, und einen frei auskragenden Arbeitsbereich 6. Der Arbeitsbereich ist durch nutartige, am Rücken 7 des Farbmessers 3 und von dessen Vorderkante 8 ausgehend angeordnete Aussparungen 9 in einzeln verstellbare, jedoch zusammenhängende Teilbereiche 10 untergliedert; jeder dieser Teilbereiche ist zur Einstellung einer Farbschichtdicke in einer Farbzone 11 mittels eines Stellgliedes 12 - im gezeigten Ausführungsbeispiel einer Stellschraube, die in der Halterung 5 drehbar gelagert ist - individuell an die Farbkastenwalze 2 anstellbar.1, 1 denotes an ink fountain, 2 denotes an ink fountain roller and 3 denotes an ink knife. The latter has a clamping area 4, with which it is clamped in a multi-part holder 5 fastened to the ink fountain 1, and a freely projecting working area 6. The working area is formed by groove-like cutouts 9 arranged on the back 7 of the ink knife 3 and from its front edge 8 divided into individually adjustable but coherent sections 10; Each of these subareas can be adjusted individually to the ink fountain roller 2 in order to set an ink layer thickness in an ink zone 11 by means of an actuator 12 - in the exemplary embodiment shown an adjusting screw which is rotatably mounted in the holder 5.

Erfindungsgemäß sind zwischen jeweils zwei benachbarten Teilbereichen 10 des Farbmessers 3 jeweils zwei nutartige Aussparungen 9 vorgesehen, die ausgehend von der Vorderkante 8 des Farbmessers zu dessen Klemmbereich hin V-förmig aufeinander zulaufen - siehe auch Fig. 2 -. Die geradlinig oder gegebenenfalls auch bogenförmig aufeinander zulaufenden nutartigen Aussparungen besitzen einen rechteckigen Querschnitt und sind derart in das Farbmesser 3 eingeformt, daß zwischen dessen Unterseite 13 und dem Nutgrund ein Biegebereich 14 - siehe Fig. 3 und 4 - mit rechteckigem Querschnitt sowie zwischen den einander zugewandten Seitenflächen der Aussparungen 9 jeweils ein keilförmiges Messerteil 15 verbleibt. Die beiden, jeweils V-förmig aufeinander zulaufenden Ausparungen 9 sind spitzwinklig zueinander angeordnet, gehen vorzugsweise unmittelbar vor dem Klemmbereich 4 ineinander über und besitzen eine Tiefe von etwa der Hälfte der Farbmesserdicke.According to the invention, two groove-like recesses 9 are provided between each two adjacent subregions 10 of the color knife 3, which run from the front edge 8 of the color knife toward its clamping area towards one another in a V-shape - see also FIG. 2. The straight or possibly also arc-shaped groove-like recesses have a rectangular cross-section and are molded into the color knife 3 such that between its underside 13 and the groove base there is a bending area 14 - see FIGS. 3 and 4 - with a rectangular cross-section and between the mutually facing ones Side faces of the recesses 9 each have a wedge-shaped knife part 15. The two recesses 9, each tapering in a V-shape, are arranged at an acute angle to one another, preferably merge into one another directly in front of the clamping region 4 and have a depth of approximately half the ink knife thickness.

Die Breite einer Farbzone 11 ist durch den Abstand zweier Mittellinien bestimmt, die durch die Mitte zweier benachbarter Paare von V-förmig aufeinander zulaufenden Aussparungen 9 verlaufen. Die Breite jeder der Farbzonen 11 bleibt aufgrund der erfindungsgemäßen Farbmessergestaltung sowohl in Farbauftragsstellung eines Teilbereiches 10 als auch in Rakelstellung desselben exakt erhalten. Zur Verdeutlichung dieses Sachverhaltes ist anhand von Fig. 3 und 4, in denen die Verhältnisse am Farbmesser 3 in Bezug auf dessen Lage zur Farbkastenwalze 2 vergrößert dargestellt sind, eine der Farbzonen 11 näher betrachtet.The width of a color zone 11 is determined by the distance between two center lines which run through the center of two adjacent pairs of recesses 9 which converge in a V-shape. The width of each of the ink zones 11 is retained exactly due to the ink knife design according to the invention both in the ink application of a partial area 10 and in the doctor blade position thereof. To clarify this fact, one of the ink zones 11 is considered in more detail with reference to FIGS. 3 and 4, in which the conditions on the ink knife 3 are shown enlarged in relation to its position relative to the ink fountain roller 2.

In Fig. 3 ist die betrachtete Farbzone 11/1 zwischen den Pfeilen vollständig, die links und rechts derselben angrenzende Farbzone 11/2 bzw. 11/3 dagegen nur teilweise dargestellt. Die Unterseite 13 des Farbmessers 3 ist, wie aus Fig. 3 ersichtlich, über die ganze dargestellte Breite gleich weit von der Farbkastenwalze 2 entfernt, so daß in allen drei dargestellten Farbzonen 11/1, 11/2 und 11/3 von der Farbkastenwalze 2 Farbe mit gleichbleibender Schichtdicke an eine nachfolgende Walze weitergeleitet wird. Bei der Anordnung der Teile nach Fig. 4 dagegen erfolgt ein Farbtransport im wesentlichen nur in den Farbzonen 11/2 und 11/3, da in der Farbzone 11/1 der zugeordnete Teilbereich 10/1 des Farbmessers 3 vollständig an die Farbkastenwalze 2 angestellt ist und die Farbe in diesem Bereich abgerakelt wird. Die Anstellung des Teilbereiches 10/1 an die Farbkastenwalze 2 erfolgt durch entsprechende Verstellung der Stellschraube 12, die dabei - wie in Fig. 2 gezeigt - etwa am Punkt 16, also nahe der Farbmesservorderkante 8 sowie mittig am betrachteten Teilbereich 10/1 angreift und diesen in Richtung Farbkastenwalze 2 drückt. Der besagte Teilbereich 10/1 verbiegt sich dabei wegen der Geometrie der an ihn angrenzenden Aussparungen 9/1, 9/2 und der Messerteile 15 nicht oder nur ganz unwesentlich ; letzteres deshalb, weil durch die beiden an den Teilbereich 10/1 angrenzenden Aussparungen 9/1 und 9/2 mit ihren querschnittsseitig geschwächten Biegebereichen 14 eine Scharnierwirkung gegeben ist, wobei sich - wie aus Fig. 4 ersichtlich - bei Anstellung des Teilbereiches 10/1 an die Farbkastenwalze 2 die Biegebereiche 14 gewissermaßen als Scharnierdrehpunkte verhaltend verbiegen, die Messerteile 15 jedoch weitgehend ihre gerade Form behalten und sich dabei im Bereich der Vorderkante 8 des Farbmessers 3 etwa wie zweiseitig eingespannte starre Träger verhalten.In Fig. 3, the considered color zone 11/1 between the arrows is complete, the color zone 11/2 or 11/3 adjacent to the left and right of the same, however, is only partially shown. The underside 13 of the color knife 3 is, as from FIG. 3 can be seen, across the entire width shown equidistant from the ink fountain roller 2, so that in all three ink zones 11/1, 11/2 and 11/3 shown by the ink fountain roller 2 color with a constant layer thickness is passed on to a subsequent roller. In contrast, in the arrangement of the parts according to FIG. 4, ink is transported essentially only in the ink zones 11/2 and 11/3, since in the ink zone 11/1 the assigned sub-area 10/1 of the ink knife 3 is completely set against the ink fountain roller 2 and the paint is scraped off in this area. The adjustment of the partial area 10/1 to the ink fountain roller 2 takes place by corresponding adjustment of the adjusting screw 12 which, as shown in FIG. 2, engages at about point 16, i.e. near the leading edge 8 of the ink knife and in the middle on the partial area 10/1 under consideration and this presses in the direction of the ink fountain roller 2. Said portion 10/1 does not bend, or only insignificantly, because of the geometry of the recesses 9/1, 9/2 and the knife parts 15 adjoining it; the latter because the two recesses 9/1 and 9/2 adjoining the partial area 10/1, with their bending areas 14 weakened on the cross-section side, give a hinge effect, which - as can be seen from FIG. 4 - occurs when the partial area 10/1 is turned on Bend the bending areas 14 to the ink fountain roller 2, to a certain extent as hinge pivot points, but the knife parts 15 largely retain their straight shape and behave in the region of the front edge 8 of the ink knife 3 approximately as rigid supports clamped on two sides.
