Abstract
Description
Die Erfindung betrifft ein Heberfarbwerk für eine Druckmaschine
gemäß dem Oberbegriff von Anspruch 1.The invention relates to a lifter inking unit for a printing press
according to the preamble of
Bei den meisten Bogenoffsetdruckmaschinen erfolgt die Farbzufuhr über mit einer Farbkastenwalze zusammenwirkenden Farbdosierelemente und einer der Farbkastenwalze nachgeordnete Heberwalze. Die Heberwalze hat zeitweise Kontakt mit der Farbkastenwalze und gibt die dabei aufgenommene Farbmenge während des Kontaktes mit einer nachgeordneten Farbwerkwalze an diese ab. Die der Heberwalze nachgeordnete Farbwerkwalze ist meist als Reiberwalze ausgeführt, d.h. diese führt in Hub und Frequenz einstellbare Changierbewegungen aus.Most sheetfed offset presses are fed with ink via ink metering elements interacting with an ink fountain roller and one downstream of the ink fountain roller Vibrator roller. The lifter roller is temporarily in contact with the Ink fountain roller and gives the amount of ink picked up during contact with a downstream inking roller to this. The inking unit roller downstream of the lifting roller is usually designed as a friction roller, i.e. this leads to hub and frequency adjustable oscillation movements.
Über den der Heberwalze nachgeordneten Walzenzug wird die durch die Heberwalze in das Farbwerk eingebrachte Farbmenge entsprechend oft gespalten, um schließlich über die Farbauftragwalzen auf die Druckform aufgetragen zu werden. Aufgabe der Farbwerkwalzen ist es, ein in Richtung Druckform weisendes Schichtdickengefälle (Duktor / Farbauftragwalzen) herzustellen. Insgesamt soll ein Heberfarbwerk eine vom Sujet unabhängige gleichmäßige Einfärbung der druckenden Bildstellen ermöglichen. Die Druckbildstellen sollen dabei mit einem Farbfilm definierter Dicke versehen werden.About the roller train downstream of the jack roller amount of ink introduced into the inking unit by the jack roller split accordingly often, finally, over the inking rollers to be applied to the printing form. task of the inking unit rollers is one pointing towards the printing form Produce layer thickness gradients (ductor / inking rollers). Overall, a lifter inking unit is said to be one of the subject Independent, even coloring of the printed image areas enable. The print image locations should be with a Color film of defined thickness can be provided.
Beim konventionellen Offsetdruck ist dem Farbwerk ein Feuchtwerk zugeordnet, wobei das Feuchten der Druckform über eine separate Feuchtauftragwalze oder kombiniert über die erste Farbauftragwalze erfolgen kann. Aus der DE 195 20 841 A1 ist eine kombinierte Farb-/Feuchtauftragwalze bekannt, welche hinsichtlich der Umfangsgeschwindigkeit mit einer Differenz zu der Umfangsgeschwindigkeit des Formzylinders (Plattenzylinder) betrieben wird. In conventional offset printing, the inking unit is a dampening unit assigned, with the dampening of the printing form over a separate dampening roller or combined over the first Ink roller can be done. From DE 195 20 841 A1 a combined ink / dampening roller known with a difference in peripheral speed to the peripheral speed of the forme cylinder (plate cylinder) is operated.
Konventionelle Heberfarbwerke von Bogenoffsetdruckmaschinen weisen eine große Anzahl von Walzen auf. Durch die Anzahl der Walzen ergibt sich eine große Fläche, was insgesamt ein ausgeprägtes Trägheitsverhalten mit entsprechend langen Reaktionszeiten bedingt. Durch die große Walzenfläche nimmt ein derartiges Farbwerk auch eine große Farbmenge auf, welche im Falle eines Farbwechsels durch einen Waschvorgang wieder entfernt werden muß. Dies bedingt entsprechend lange Waschzeiten. Durch den zeitweisen Kontakt der Heberwalze mit der nachgeordneten Farbwerkwalze (Reiber) wird ferner auch ein Impuls in den Walzenzug des Farbwerkes übertragen, der Druckstörungen bewirken kann. Weiterhin entsteht zusätzlich zu der Unstetigkeit des Farbtransportes durch den Heber ein sogenannter Hebereinsatzstreifen, welcher durch Spaltvorgänge und somit eine entsprechende Anzahl von Walzen im Farbwerk wieder ausgeglichen werden muß. Eine große Anzahl von Walzen im Farbwerk bedingt ferner auch hohe Herstellungskosten.Conventional lifter inking units of sheetfed offset presses have a large number of rollers. By the number of Rolling results in a large area, which is a total pronounced inertia behavior with correspondingly long Response times conditional. Due to the large roller area such an inking unit also has a large amount of ink, which in the event of a color change by washing again must be removed. This requires correspondingly long washing times. Due to the temporary contact of the lifting roller with the downstream inking roller (Reiber) is also a Impulse transferred to the roller of the inking unit, the pressure disturbances can effect. Furthermore, in addition to the Discontinuity of the color transport through the lifter a so-called Lifter insert strips, which by splitting processes and thus a corresponding number of rollers in the inking unit again must be balanced. A large number of rollers in the Inking unit also entails high manufacturing costs.
Aus der DE-A-2 309 850 ist ein Farbwerk für eine Rotationsdruckmaschine bekannt, bei welchem die an der Heberwalze nachgeordneten Reiberwalzen unterschiedliche und gegenüber dem Druckformzylinder reduzierte Umfangsgeschwindigkeiten aufweisen. Die der Heberwalze direkt nachgeordnete Reiberwalze weist dabei eine geringere Umfangsgeschwindigkeit auf als die über eine Zwischenwalze nachgeordnete zweite Reiberwalze.From DE-A-2 309 850 an inking unit for a rotary printing press is known from which the different friction rollers arranged on the jack roller different and have reduced peripheral speeds compared to the printing form cylinder. The the friction roller directly downstream of the lifting roller has a lower one Peripheral speed on than the second downstream via an intermediate roller Distributor roller.
Aufgabe der vorliegenden Erfindung ist es, ein Heberfarbwerk
für Druckmaschinen gemäß dem Oberbegriff von Anspruch 1
derartig zu erweitern, so daß unter Vermeidung der zuvorstehend
genannten Nachteile die Anzahl der in einem Farbwerk
vorzusehenen Walzen verringert werden kann.The object of the present invention is a lifter inking unit
for printing presses according to the preamble of
Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale
von Anspruch 1. Weiterbildungen der Erfindung ergeben sich
aus den Unteransprüchen.This task is solved by the characteristic features
of
Gemäß der Erfindung ist vorgesehen, daß die mit der Druckform in Kontakt stehenden Auftragwalzen sowie die vorgeordneten Farbwerkwalzen eine Umfangsgeschwindigkeit aufweisen, die der Umfangsgeschwindigkeit des Druckformzylinders entspricht. Eine zweite Gruppe Farbwerkwalzen wird durch die Heberwalze sowie der Heberwalze nachgeordnete Walzen gebildet, wobei diese Walzen eine Umfangsgeschwindigkeit aufweisen, welche gegenüber der Umfangsgeschwindigkeit des Druckformzylinders (Druckform) stark verringert ist. Hier können Differenzgeschwindigkeiten zwischen vorzugsweise 8% und 15% vorgesehen sein.According to the invention it is provided that with the printing form contact rollers and the upstream ones Inking rollers have a peripheral speed that the Corresponds to the peripheral speed of the printing form cylinder. A second group of inking rollers is through the siphon roller and rollers arranged downstream of the lifting roller, wherein these rollers have a peripheral speed which compared to the peripheral speed of the printing form cylinder (Printing form) is greatly reduced. Differential speeds can be found here between preferably 8% and 15% his.
Durch die hinsichtlich der Umfangsgeschwindigkeit vorgenommene Unterteilung des Walzenzuges ergibt sich an einer Spaltstelle zwischen den entsprechenden Walzen ein Schlupf. Durch diesen Schlupf wird die in die Spaltstelle eingeförderte große Schichtdicke der die Farbe zuführenden Walze (Umfangsgeschwindigkeit gegenüber Druckform verringert) in eine geringe Farbschichtdicke der farbabnehmenden Walze gespalten. Dadurch ergibt sich eine Schichtdickenänderung, wie diese sonst nur durch mehrere Walzen und entsprechende Spaltstellen erzielt wird.Because of the circumferential speed Subdivision of the single drum roller results at a nip a slip between the corresponding rollers. By this slip is introduced into the gap large layer thickness of the roller feeding the ink (peripheral speed reduced compared to printing form) in one split the thin ink layer thickness of the ink-removing roller. This results in a change in layer thickness like this otherwise only through several rollers and corresponding nips is achieved.
Das erfindungsgemäße Farbwerk weist im Walzenzug zwischen Heberwalze und Druckform wenigstens eine Schlupfwalze auf, welche im Vergleich zur Umfangsgeschwindigkeit der Druckform (Druckformzylinder) eine schwach reduzierte Umfangsgeschwindigkeit ausführt, wobei diese Umfangsgeschwindigkeit aber noch höher ist als die der Heberwalze nachgeordneten Walzen. Eine derartige Schlupfwalze weist so mindestens zwei Schlupfstellen auf, nämlich einmal mit der langsamer drehenden vorgeordneten und einmal mit der schneller drehenden nachgeordneten Walze (Umfangsgeschwindigkeit der Druckform).The inking unit according to the invention points in the roller train between the lifting roller and printing form at least one slip roller, which in Comparison to the peripheral speed of the printing form (printing form cylinder) a slightly reduced peripheral speed executes, but this peripheral speed is even higher is than the rollers downstream of the lifting roller. Such The slip roller thus has at least two slip points on, namely once with the slower rotating upstream and once with the faster rotating downstream roller (Peripheral speed of the printing form).
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung kann vorgesehen sein, daß die der Heberwalze nachgeordnete Farbwerkwalze mit zwei Schlupfwalzen in Kontakt steht, wobei diese Schlupfwalzen wiederum mit zwei weiteren mit Umfangsgeschwindigkeit des Druckformzylinders rotierenden Walzen in Kontakt steht. Somit ergeben sich insgesamt vier Schlupfstellen, welche einen optimalen Ausgleich (Glättung) des Heberstreifens bewirken. Zur Aufteilung des Farbflusses führen die Schlupfwalzen vorzugsweise zueinander unterschiedliche Umfangsgeschwindigkeiten aus.According to a further preferred embodiment of the invention can be provided that the downstream of the lifting roller Inking roller is in contact with two slip rollers, these slip rollers in turn with two more Rotating peripheral speed of the printing form cylinder Rollers is in contact. This results in a total of four Hatches, which optimal compensation (smoothing) of the squeegee strip. For dividing the color flow guide the slip rollers preferably different from each other Peripheral speeds.
Eine weitere bevorzugte Ausführungsform der Erfindung sieht vor, daß die der Heberwalze nachgeordnete und mit gegenüber der Druckform stark verringerter Umfangsgeschwindigkeit rotierende Walze mit einer Schlupfwalze in Kontakt steht und diese Schlupfwalze (Umfangsgeschwindigkeit gegenüber Druckform schwach verringert) mit zwei weiteren mit Umfangsgeschwindigkeit der Druckform rotierenden Walzen zusammenwirkt. Diese Schlupfwalze weist also insgesamt drei Schlupfstellen auf, wobei diese Schlupfwalze über die eine Spaltstelle Farbe aufnimmt und über die beiden anderen Schlupfstellen Farbe an die übrigen Farbwalzen abgibt.Another preferred embodiment of the invention provides that the subordinate to the lifter roller and opposite the printing form greatly reduced peripheral speed rotating roller is in contact with a slip roller and this slip roller (peripheral speed compared to printing form weakly reduced) with two others at peripheral speed the printing form rotating rollers cooperates. This slip roller therefore has a total of three slip points on, this slip roller over the one nip paint picks up and takes on color over the other two hatches releases the remaining ink rollers.
Die Unterteilung des erfindungsgemäßen Heberfarbwerkes in Walzen mit wenigstens zwei Umfangsgeschwindigkeiten erfolgt vorzugsweise dadurch, daß die mit der Umfangsgeschwindigkeit der Druckform bzw. des Druckformzylinders angetriebenen Walzen über einen Räderzug direkt von diesem getrieben werden. Dabei kann vorgesehen sein, daß die Changierbewegungen ausführenden Reiber über einen Räderzug (Getriebezug) vom Druckformzylinder her getrieben werden und über Friktionen die Farbauftragwalzen treiben. Die mit gegenüber der Umfangsgeschwindigkeit der Druckform herabgesetzter Umfangsgeschwindigkeit rotierenden Walzen des Farbwerkes können über Untersetzungsgetriebe vom Druckformzylinder her angetrieben werden, wobei die der Heberwalze erstnachfolgende Schlupfwalze einen eigenen steuerbaren Antrieb aufweist. The division of the lifter inking unit according to the invention into Rolling takes place with at least two peripheral speeds preferably in that the peripheral speed the printing form or the printing form cylinder driven Rollers can be driven directly by a gear train. It can be provided that the traversing movements executing friction on a gear train from Printing form cylinders are driven here and over friction drive the inking rollers. The one with the peripheral speed the printing form reduced peripheral speed rotating rollers of the inking unit can via reduction gears are driven by the printing form cylinder, the slip roller only following the lifting roller has its own controllable drive.
