Description

Die Erfindung betrifft ein umstellbares Heber-/ Filmfarbwerk mit einer an einem Farbkasten angeordneten Farbkastenwalze, einer den nachgeschalteten Farbwalzen Farbe zuführenden Farbwerkwalze, einer an die Farbkastenwalze anstellbaren und davon wegschwenkbaren Heberwalze, deren Schwenkmechanismus im.Filmbetrieb abschaltbar ist, sowie einer zusätzlichen Walze mit einer harten Walzenoberfläche, die im Filmbetrieb an die Farbkastenwalze und die Farbwerkwalze anstellbar ist.The invention relates to a convertible lifter / film inking unit with an ink fountain roller arranged on an ink fountain, an ink fountain roller supplying ink to the downstream ink rollers, a lifting roller which can be adjusted to the ink fountain roller and can be swung away therefrom, the swiveling mechanism of which can be switched off in film operation, and an additional roller with a hard roller Roller surface that can be adjusted to the ink fountain roller and the inking roller in film operation.

Aus der DE-A-2703424 ist ein Farbwerk für Offset-Druckmaschinen der vorangehend spezifizierten Art bekannt. Bei diesem einstellbaren Farbwerk liegt nur die zusätzliche Farbabnahmewalze zwischen der Farbkastenwalze und der Farbwerkwalze, wobei im Heberbetrieb eine Heberwalze zwischen der in einem Farbkasten angeordneten Farbkastenwalze und der zusätzlicheh Farbabnahmewalze verschwenkt wird. Zur Umstellung dieses bekannten Farbwerkes für den Filmbetrieb wird die genannte Farbabnahmewalze direkt an die Farbkastenwalze angestellt, so daß sie als Filmwalze arbeitet, während die Heberwalze in permanenter Anlage mit der Farbabnahmewalze verbleibt, so daß sie als Reiterwalze wirkt. Ein gleichzeitiger Heber-/Filmbetrieb ist mit dieser Anordnung nicht möglich.From DE-A-2703424 an inking unit for offset printing machines of the type specified above is known. In this adjustable inking unit, only the additional ink take-up roller lies between the ink fountain roller and the inking roller, a lifting roller being pivoted between the ink fountain roller arranged in an ink fountain and the additional ink take-off roller during lifting operation. In order to convert this known inking unit for film operation, the said ink take-off roller is placed directly on the ink fountain roller so that it works as a film roller, while the lifter roller remains in permanent contact with the ink take-off roller so that it acts as a rider roller. Simultaneous lifting / film operation is not possible with this arrangement.

Aufgabe der Erfindung ist es, ein umstellbares Farbwerk der eingangs genannten Art so auszubilden, daß im Heberbetrieb die Heberwalze mit der Farbkastenwalze und der Farbwerkwalze zusammenwirkt, wobei auch ein gleichzeitiger kombinierter Heber-/Filmbetrieb möglich sein soll.The object of the invention is to provide a convertible inking unit of the type mentioned in such a way that the lifting roller interacts with the ink fountain roller and the inking unit roller in the lifting operation, a simultaneous combined lifting / film operation should also be possible.

Diese Aufgabe wird gemäß dem Kennzeichen des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie aus der Beschreibung in Verbindung mit den Zeichnungen.This object is achieved in accordance with the characterizing part of patent claim 1. Advantageous developments of the invention result from the subclaims and from the description in conjunction with the drawings.

Ein Vorteil der Erfindung besteht darin, daß die Ausbildung der Walzenoberflächen den Bedingungen für den Heberbetrieb und für den Filmbetrieb individuell angepaßt werden kann. So kann z. B. die mit der Heberwalze zusammenwirkende Farbwerkwalze eine glatte Oberfläche aufweisen, während die im Filmbetrieb mit der Farbkastenwalze zusammenarbeitende Walze eine strukturierte Oberfläche erhalten kann. Ein weiterer Vorteil liegt in der kombinierten Heber-/ Filmbetriebsweise, bei der ohne wesentlichen Mehraufwand den nachgeschalteten Farbwalzen die Farbe sowohl für die Filmwalze als auch über die Heberwalze, d. h. über zwei Wege, zuführbar ist. Das erfindungsgemäße umstellbare Farbwerk kann somit in einem von drei Modi betrieben werden, nämlich Heberbetrieb, Filmbetrieb oder kombiniertem Betrieb.An advantage of the invention is that the design of the roller surfaces can be individually adapted to the conditions for the lifting operation and for the film operation. So z. B. the inking roller cooperating with the jack roller have a smooth surface, while the roller cooperating with the ink fountain roller in film operation can have a structured surface. A further advantage lies in the combined lifter / film mode of operation, in which the ink is connected to the downstream inking rollers without any significant additional effort, both for the film roller and via the lifter roller, ie. H. can be fed in two ways. The convertible inking unit according to the invention can thus be operated in one of three modes, namely lifting operation, film operation or combined operation.

Die Erfindung wird im folgenden anhand von Ausführungsbeispielen im einzelnen beschrieben, wobei Bezug auf die Zeichnungen genommen wird. In diesen zeigt

  • Fig. 1 eine schematische Darstellung des oberen Teiles eines umstellbaren Heber-/Film farbwerkes, und
  • Fig. 2 eine modifizierte Ausführungsform des Farbwerkes nach Fig. 1.
The invention is described in detail below on the basis of exemplary embodiments, reference being made to the drawings. In these shows
  • Fig. 1 is a schematic representation of the upper part of an adjustable lifter / film inking unit, and
  • 2 shows a modified embodiment of the inking unit according to FIG. 1.

In Fig. 1 ist schematisch der obere Teil eines umstellbaren Heber-/Filmfarbwerkes dargestellt, der in bekannter Weise mit einer Anzahl nicht näher bezeichneter Farbübertragungswalzen und -reiber zur Einfärbung eines Plattenzylinders (nicht gezeigt) verwendet wird.In Fig. 1, the upper part of a convertible lifter / film inking unit is shown schematically, which is used in a known manner with a number of ink transfer rollers and ink drivers (not shown) for inking a plate cylinder (not shown).

Der in Fig. 1 dargestellte Teil des umstellbaren Farbwerkes umfaßt eine angetriebene an einem Farbkasten 1 angeordnete Farbkastenwalze 2, eine Heberwalze 3, die durch einen schematisch angedeuteten Schwenkmechanismus 4 zwischen der Farbkastenwalze 2 und einer angetriebenen Farbwerkwalze 5, die beispielsweise als Reiber ausgebildet sein kann und deren Oberfläche mit annähernder oder genauer Plattenzylinderumfangsgeschwindigkeit rotiert, verschwenkbar ist sowie eine durch Reibung mitgenommene zusätzliche Walze 6 mit harter Oberfläche, die zwischen die Farbkastenwalze und die Farbwerkwalze 5 anstellbar ist.The part of the convertible inking unit shown in FIG. 1 comprises a driven ink fountain roller 2 arranged on an ink fountain 1, a lifting roller 3, which is shown by a schematically indicated pivot mechanism 4 between the ink fountain roller 2 and a driven inking roller 5, which can be designed, for example, as a grater and the surface of which rotates at an approximately or precise plate cylinder circumferential speed, can be pivoted, and an additional roller 6 with a hard surface, which is entrained by friction and which can be set between the ink fountain roller and the inking roller 5.

Die Walze 6 ist eine sogenannte harte Walze, d. h. sie weist eine harte Oberfläche beispielsweise aus Stahl auf, die strukturiert sein kann. Vorzugsweise wird als Farbkastenwalze 2 eine Gußwalze verwendet und die Oberfläche der Heberwalze 3 sowie der Walze 7 (Fig. 2) sind gummiert. Die Farbwerkwalze 5 ist ebenfalls eine sogenannte harte Walze. Sie kann mit einem harten Kunststoff beschichtet sein, z. B. mit Rilsan.The roller 6 is a so-called hard roller, i. H. it has a hard surface, for example made of steel, which can be structured. A cast roller is preferably used as the ink fountain roller 2 and the surface of the lifting roller 3 and the roller 7 (FIG. 2) are rubberized. The inking roller 5 is also a so-called hard roller. It can be coated with a hard plastic, e.g. B. with Rilsan.

Die Antriebsmechanismen der Farbkastenwalze 2 und der Farbwerkwalze 5 sind im einzelnen nicht gezeigt, da sie allgemeiner Stand der Technik sind. Das gleiche gilt für die Anstellvorrichtung der Film- bzw. Heberwalze. Im Heberbetrieb wird die Heberwalze 3 durch den Schwenkmechanismus 4 zwischen der Farbkastenwalze 2 und der Farbwerkwalze 5 hin- und hergeschwenkt. Soll nun das Farbwerk als Filmfarbwerk arbeiten, so wird zunächst der Schwenkmechanismus 4 abgestellt und die Heberwalze 3 vorzugsweise an die Farbwerkwalze 5 angestellt, so daß sie als Reiterwalze arbeitet. Gegebenenfalls ist jedoch auch eine Fixierung der Heberwalze 3 in einer mittleren Stellung möglich, bei der sie weder mit der Farbkastenwalze 2 noch mit der Farbwerkwalze 5 in Verbindung steht. Für den Filmbetrieb braucht dann lediglich die Walze 6, die im Heberbetrieb vorzugsweise an die Farbwerkwalze 5 angestellt ist und somit als Reiterwalze wirkt, an die Farbkastenwalze 2 angestellt werden, was durch die strichpunktierte Stellung 6' angedeutet ist. Die für diesen Vorgang erforderlichen Einstellmittel, z. B. exzentrische Lagerung, Pneumatikzylinder usw., sind allgemein bekannt und deshalb nicht dargestellt. Da die Walze 6 durch Friktion von der Farbwerkwalze 5 her oder zwangsweise angetrieben wird und somit ebenfalls mit annähernd Plattenzylindergeschwindigkeit umläuft, während die Farbkastenwalze 2 mit einer wesentlich niedrigeren Geschwindigkeit angetrieben wird, muß zwischen der Walze 6 und der Farbkastenwalze 2 ein entsprechender Farbübertragungsspalt eingehalten werden.The drive mechanisms of the ink fountain roller 2 and the inking roller 5 are not shown in detail since they are general prior art. The same applies to the adjusting device of the film or lifter roller. In the lifting operation, the lifting roller 3 is pivoted back and forth between the ink fountain roller 2 and the inking roller 5 by the pivot mechanism 4. If the inking unit is now to work as a film inking unit, the swivel mechanism 4 is first switched off and the lifting roller 3 is preferably set against the inking unit roller 5, so that it works as a rider roller. If necessary, however, it is also possible to fix the lifter roller 3 in a middle position in which it is not connected to the ink fountain roller 2 or to the inking roller 5. For the film operation then only the roller 6, which is preferably placed on the inking roller 5 in the lifting operation and thus acts as a rider roller, needs to be turned on the ink fountain roller 2, which is indicated by the dot-dash position 6 '. The setting means required for this process, e.g. B. eccentric bearings, pneumatic cylinders, etc., are generally known and therefore not shown. Since the roller 6 is driven by friction from the inking roller 5 or forcibly and thus also rotates at approximately plate cylinder speed while the ink box roller 2 is driven at a much lower speed, a corresponding ink transfer gap must be maintained between the roller 6 and the ink fountain roller 2.

Ein wesentlicher Vorteil des erfindungsgemäßen Farbwerkes besteht in der Möglichkeit, dieses in kombinierter Betriebsweise arbeiten zu lassen. Dies ist bei einer Anstellung der Walze 6 an die Farbkastenwalze 2 und an die Farbwerkwalze 5 und durch gleichzeitige Aktivierung der Heberwalze 3 mittels des Schwenkmechanismus 4 möglich. Dadurch kann quasi parallel Farbe einmal von der Farbkastenwalze 2 über die Walze 6 zu der Farbwerkwalze 5 und zum anderen von der Farbkastenwalze 2 über die Heberwalze zu der Farbwerkwalze 5 transportiert werden.A major advantage of the inking unit according to the invention is the possibility of having it work in a combined mode of operation. This is possible when the roller 6 is positioned against the ink fountain roller 2 and the inking roller 5 and by simultaneous activation of the lifting roller 3 by means of the swivel mechanism 4. As a result, ink can be transported in a quasi-parallel manner from the ink fountain roller 2 via the roller 6 to the inking roller 5 and secondly from the ink fountain roller 2 via the lifting roller to the inking roller 5.

Bei der Ausführungsform gemäß Fig. 1 arbeitet im Filmbetrieb und im kombinierten Betrieb die harte Walze 6 mit der harten Farbwerkwalze 5 zusammen. Da sich beide Walzen annähernd mit gleicher Umfangsgeschwindigkeit drehen, ist dies wenig problematisch. Es kann jedoch vorteilhaft sein, jeweils eine Walze mit harter Oberfläche und eine Walze mit weicher Oberfläche zusammenwirken zu lassen. Diese Walzenfolge ist bei der modifizierten Ausführungsform nach Fig. möglich. In Fig. ist zwischen der Walze 6 und der Farbwerkwalze 5 eine Walze 7 mit weicher Oberfläche angeordnet. Die Walze 7 steht zweckmäßigerweise ständig in Kontakt mit der Farbwerkwalze 5 und mit der Walze 6. Dies gilt für alle drei Betriebsarten. Die weiche Walze 7 arbeitet somit ständig auf der Farbwerkwalze 5 als Reiterwalze. Bei der Ausführungsform gemäß Fig. 2 wird dann lediglich die ständig mit der weichen Walze 7 in Verbindung stehende Walze 6 für den Filmbetrieb und den kombinierten Betrieb an die Farbkastenwalze 2 angestellt, was durch das Bezugszeichen 6' angedeutet ist.In the embodiment according to FIG. 1, the hard roller 6 works together with the hard inking roller 5 in film operation and in combined operation. Since both rollers rotate at approximately the same peripheral speed, this is not a problem. However, it can be advantageous to have a roller with a hard surface and a roller with a soft surface interact. This roller sequence is possible in the modified embodiment according to FIG. In Fig. A roller 7 is arranged with a soft surface between the roller 6 and the inking roller 5. The roller 7 is expediently in constant contact with the inking roller 5 and with the roller 6. This applies to all three operating modes. The soft roller 7 thus works continuously on the inking roller 5 as a rider roller. In the embodiment according to FIG. 2, only the roller 6, which is constantly connected to the soft roller 7, is turned on the ink fountain roller 2 for film operation and combined operation, which is indicated by the reference symbol 6 '.

In der gleichen Weise wie bei der Vorrichtung gemäß Fig. 1 wird die Heberwalze 3 abwechselnd an die Farbkastenwalze 2, was durch das Bezugszeichen 3' angedeutet ist, und an die Farbwerkwalze 5 durch den Schwenkmechanismus4 angelegt.In the same way as in the device according to FIG. 1, the lifting roller 3 is alternately applied to the ink fountain roller 2, which is indicated by the reference symbol 3 ', and to the inking roller 5 by the pivot mechanism 4.

In den vorangehend beschriebenen Ausführungsbeispielen arbeiten die Heberwalze 3 im Filmbetrieb als Reiterwalze auf der Farbwerkwalze 5 und die Walze 6 bzw. die Walze 7 im Heberbetrieb als Reiterwalze auf der Farbwerkwalze 5. Dies bietet Vorteile, da der Farbfilm auf der Farbwerkwalze 5 zusätzlich günstig beeinflußt, d. h. vergleichmäßigt wird. Ein weiterer Vorteil bei der kombinierten Betriebweise besteht darin, daß durch die Heberwalze 3 überschüssiges Feuchtmittel in den Farbkasten zurücktransportiert werden kann.In the exemplary embodiments described above, the lifter roller 3 works in film operation as a rider roller on the inking unit roller 5 and the roller 6 or roller 7 in lifting operation as a rider roller on the inking unit roller 5. This offers advantages since the ink film on the inking unit roller 5 also has a favorable effect, d. H. is evened out. Another advantage of the combined mode of operation is that excess dampening solution can be transported back into the ink fountain by the lifter roller 3.
