Abstract

The invention relates to a printing machine with an inking unit and a dampening unit which interact by means of ink and moisture spreading rollers with a printing forme, and with a control device for displacement of the moisture spreading roller into a contact or separation position in relation to the printing forme. For simple handling in particular, it is envisaged that, for application of a gumming to the printing forme (8), the moisture spreading roller (7) is supplied with a gumming liquid (13) by a gumming device (11) and is displaced into its contact position in relation to the printing forme (8) by the control device. <IMAGE>

Description

Die Erfindung betrifft eine Druckmaschine mit einem Farb- und einem Feuchtwerk, welche mittels Farb- und Feuchtauftragwalzen mit einer Druckform zusammenwirken, und mit einer Steuereinrichtung zur Verlagerung der Feuchtauftragwalze in eine Anlage- bzw. Abstandsstellung zur Druckform.The invention relates to a printing press with an inking and dampening unit, which cooperate with a printing form by means of inking and dampening application rollers, and with a control device for displacing the dampening application roller into a contact or spacing position from the printing form.

Wenn ein Druckvorgang beendet wird (z.B. Abstellen einer Offset-Druckmaschine über Nacht), so ist es zweckmäßig, die Druckplatte vor Umwelteinflüssen, die z.B. Korrosion verursachen können, zu schützen. Hierzu wird ein sogenanntes Gummierungsmittel eingesetzt, das z.B. Gummiarabikum enthält. Das Gummierungsmittel wird vom Drucker auf die Druckplatte aufgetragen, wodurch sich eine Schutzschicht bildet, die bei der Wiederaufnahme des Druckvorgangs vom Drucker wieder zu entfernen ist. Das bisherige Vorgehen ist zeitaufwendig und - in bezug auf das Entfernen der Schutzschicht aufgrund der einzusetzenden chemischen Mittel - gegebenenfalls nur in Verbindung mit Schutzmaßnahmen durchführbar.When a printing process is ended (e.g. parking an offset printing machine overnight), it is advisable to protect the printing plate from environmental influences, e.g. Can cause corrosion to protect. A so-called gumming agent is used for this purpose, e.g. Contains gum arabic. The gum is applied by the printer to the printing plate, creating a protective layer that must be removed by the printer when printing is resumed. The previous procedure is time-consuming and - with regard to the removal of the protective layer due to the chemical agents to be used - can possibly only be carried out in conjunction with protective measures.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Druckmaschine der eingangs genannten Art anzugeben, bei der auf rationelle und gesundheitlich unbedenkliche Weise das Gummieren der Druckform durchführbar ist. Ferner soll auch auf einfache Weise das Entfernen der Gummierung vorgenommen werden können.The invention is therefore based on the object of specifying a printing press of the type mentioned at the beginning, in which the gumming of the printing form can be carried out in a rational and harmless manner. Furthermore, it should also be possible to easily remove the rubber coating.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zum Aufbringen einer Gummierung auf die Druckform der Feuchtauftragwalze eine in eine Wanne für Gummierungsflüssigkeit eintauchende Gummierungs-Tauchwalze zugeordnet ist. Das Aufbringen der Gummierung erfolgt also nicht mehr manuell, sondern wird automatisch mittels des Feuchtwerks, insbesondere der Feuchtauftragwalze, in der Druckmaschine vorgenommen. Ein Ausbau der zu konservierenden Druckform, insbesondere Druckplatte (Aluminiumplatte), aus der Offset-Druckmaschine ist daher nicht erforderlich. Die im "Normalbetrieb" (z.B. Fortdruckzustand) ein Feuchtmittel zur Druckform liefernde Feuchtauftragwalze übernimmt daher erfindungsgemäß eine Doppelfunktion, indem sie während des Gummierungsvorgangs die Gummierungsflüssigkeit auf die Druckform überträgt. Hierbei fördert die Gummierungs-Tauchwalze die Gummierungsflüssigkeit aus einer Wanne und überträgt einen Gummmierungsfilm auf die Feuchtauftragwalze, die wiederum die übertragung auf die Druckform vornimmt.This object is achieved in that for applying a rubber coating on the printing forme of the dampening roller is assigned a rubber plunging roller immersed in a tub for rubberizing liquid. The application of the rubber coating is no longer done manually, but is automatically done by means of the Dampening unit, especially the dampening roller, made in the printing press. It is therefore not necessary to remove the printing form to be preserved, in particular the printing plate (aluminum plate), from the offset printing press. The dampening roller supplying a dampening solution to the printing form in "normal operation" (for example in the state of the printing press) therefore performs a double function according to the invention in that it transfers the gumming liquid to the printing form during the gumming process. The rubberizing plunger roller conveys the rubberizing liquid from a tub and transfers a rubber lubricating film to the dampening roller, which in turn carries out the transfer to the printing form.

Es ist bekannt, das Feuchtwerk von Offset-Druckmaschinen mit einem Reibzylinder zu versehen, der maschinenangetrieben ist und mit der Feuchtauftragwalze zusammenwirkt. Die Feuchtauftragwalze erhält über den Reibzylinder ein zusätzliches Antriebsmoment, so daß Schlupffreiheit zur Druckform besteht - Bei der Druckform handelt es sich vorzugsweise um die bereits erwähnte Druckplatte, die auf einen Plattenzylinder der Offset-Druckmaschine aufgespannt ist. Der erwähnte Reibzylinder wird vorzugsweise zur übertragung des Gummierungsmittels zur Feuchtauftragwalze verwendet, indem dieser ein Bindeglied zwischen der Gummierungs-Tauchwalze und der Feuchtauftragwalze bildet.It is known to provide the dampening unit of offset printing presses with a distribution cylinder which is machine-driven and which interacts with the dampening application roller. The dampening roller receives an additional drive torque via the distribution cylinder, so that there is no slip to the printing form. The printing form is preferably the printing plate already mentioned, which is clamped onto a plate cylinder of the offset printing press. The mentioned distribution cylinder is preferably used for the transfer of the rubberizing agent to the dampening roller by forming a link between the rubberizing dipping roller and the dampening roller.

Alternativ ist es jedoch auch möglich, eine Sprühvorrichtung zu verwenden, die die Feuchtauftragwalze und/oder den Reibzylinder mit Gummierungsflüssigkeit versorgt. Das heißt, die Gummierungsflüssigkeit wird auf die Mantelfläche der Feuchtauftragwalze und/oder des Reibzylinders aufgesprüht.Alternatively, however, it is also possible to use a spraying device which supplies the dampening roller and / or the distribution cylinder with gumming liquid. This means that the gumming liquid is sprayed onto the outer surface of the dampening roller and / or the distribution cylinder.

Ferner betrifft die Erfindung ein Verfahren zum Gummieren einer Druckform einer Druckmaschine, insbesondere Offset-Druckmaschine, die ein Farb- und ein Feuchtwerk aufweist, wobei die Zuführung der Gummierungsflüssigkeit auf die Druckform über eine Feuchtauftragwalze des Feuchtwerks erfolgt.The invention further relates to a method for gumming a printing form of a printing press, in particular an offset printing press, which has an inking and a dampening unit has, the supply of the gumming liquid to the printing form via a dampening roller of the dampening unit.

Um, wie erwähnt, einerseits das Einmischen von zu viel Feuchtmittel in die Gummierungsflüssigkeit zu verhindern und andererseits nur möglichst wenig oder kein Gummierungsmittel einer Feuchtmittelliefereinrichtung zuzuführen, ist vorgesehen, daß während des Gummierungsvorgangs die Verbindung zwischen der Feuchtauftragwalze und einer Feuchtmittelliefereinrichtung unterbrochen oder auf eine möglichst kleine Feuchtmittelfördermenge eingestellt wird.In order, as mentioned, on the one hand to prevent the mixing of too much dampening solution into the gumming liquid and on the other hand to supply as little or no gumming agent to a dampening solution supply device, it is provided that during the gumming process the connection between the dampening application roller and a dampening solution supply device is interrupted or to the smallest possible Dampening solution flow rate is set.

Zur Entfernung der Gummierung von der Druckform ist es möglich, einen in der Druckmaschine erfolgenden Waschvorgang durchzuführen. Bei diesem Waschvorgang nimmt die Feuchtauftragwalze ihre Anlagestellung zum Plattenzylinder ein, so daß beim Abwaschen der auf den Plattenzylinder aufgespannten Druckplatte die Waschflüssigkeit auch zur Feuchtauftragwalze gelangt, so daß dort vorhandene Gummierungsreste ebenfalls entfernt werden. Insbesondere erfolgt bei diesem Waschvorgang eine Trennung zur Feuchtmittelliefereinrichtung, das heißt, die Waschflüssigkeit gelangt nicht in das Feuchmittelreservoir der Druckmaschine. Bei diesem Waschvorgang kann ferner zur Reinigung eines dem Feuchtwerk angehörenden Reibzylinders dieser in seine Anlagestellung zur Feuchtauftragwalze verlagert werden, so daß sowohl die Druckform und die Feuchtauftragwalze als auch der Reibzylinder von der Gummierung bzw. von Gummierungsrestren befreit werden.To remove the rubber coating from the printing form, it is possible to carry out a washing process which takes place in the printing press. In this washing process, the dampening roller takes up its contact position with the plate cylinder, so that when the printing plate clamped on the plate cylinder is washed, the washing liquid also reaches the dampening roller, so that any gum residues present there are also removed. In particular, this washing process separates the dampening solution delivery device, that is, the washing liquid does not get into the dampening solution reservoir of the printing press. In this washing process can also be moved to cleaning a dampening cylinder belonging to the dampening unit in its contact position to the dampening roller, so that both the printing form and the dampening roller and the distribution cylinder are freed from the rubber coating or from gumming residues.

Fig. 1 zeigt einen Teil der Walzen einer Offset-Druckmachine in schematischer Darstellung. wesentliche Komponenten der Offset-Druckmaschine, wie z.B. das Farbwerk, der Gummituchzylinder und der Druckzylinder sind der Einfachheit halber nicht dargestellt.
Aus Fig. 1 geht ein Feuchtwerk 1 mit einer Feuchtmittelliefereinrichtung 2 hervor, die eine mit Feuchtmittel 3 gefüllte Feuchtmittelwanne 4 aufweist. Eine mit Antrieb versehene Feuchtmittel-Tauchwalze 5 taucht mit einem Abschnitt ihrer Mantelfläche in das Feuchtmittel 3 ein.Fig. 1 shows a part of the rollers of an offset printing machine in a schematic representation. essential components of the offset printing press, such as the inking unit, the blanket cylinder and the printing cylinder are not shown for the sake of simplicity.
1 shows a dampening unit 1 with a dampening solution delivery device 2, which has a dampening solution trough 4 filled with dampening solution 3. A dampening solution immersion roller 5 provided with a drive dips into the dampening solution 3 with a portion of its outer surface.

Das Feuchtwerk 1 weist ferner eine Dosierwalze 6 auf, die über ein Zahnradgetriebe mit der Feuchtmittel-Tauchwalze 5 gekuppelt ist.- Mit der Dosierwalze 6 wirkt eine Feuchtauftragwalze 7 zusammen, die in Anlagestellung in Kontakt mit einer Druckform 8 tritt. Die Druckform 8 ist vorzugsweise als auf einem Plattenzylinder 9 aufgespannte Druckplatte (nicht dargestellt) ausgebildet.The dampening unit 1 also has a metering roller 6, which is coupled to the dampening solution immersion roller 5 via a gear mechanism. A dampening roller 7 cooperates with the metering roller 6 and comes into contact with a printing plate 8 in the contact position. The printing form 8 is preferably designed as a printing plate (not shown) clamped on a plate cylinder 9.

Ferner ist ein angetriebener Reibzylinder 10 vorgesehen, der mit der Feuchtauftragwalze 7 zusammenwirkt.Furthermore, a driven distribution cylinder 10 is provided which interacts with the dampening roller 7.

Im Fortdruckbetrieb der Offset-Druckmaschine wird das Feuchtmittel 3 von der Feuchtmittel-Tauchwalze 5 als dünner Feuchtfilm zur Dosierwalze 6 übertragen und gelangt von dort über die Feuchtauftragwalze 7 zur Druckform 8. Die Dosierung des Feuchtmittels erfolgt einerseits durch Variation des Schlupfs zwischen der Dosierwalze 6 und der Feuchtauftragwalze 7. Der Reibzylinder 10 hat die Aufgabe, Feuchtmittelpartikel (insbesondere Wasser) in die auf der Feuchtauftragwalze befindliche Farbe eines (nicht dargestellten) Farbwerks einzuarbeiten. Diese Farbe stammt von der Druckform 8 und gegebenenfalls von einer Zwischenwalze, die in Anlagestellung zu einer Farbwerkwalze und zur Feuchtauftragwalze 7 steht. Insoweit bildet die Zwischenwalze ein Verbindungsglied zwischen dem Feuchtwerk 1 und dem Farbwerk (nicht dargestellt).In the continuous printing operation of the offset printing machine, the dampening solution 3 is transferred from the dampening solution immersion roller 5 as a thin dampening film to the metering roller 6 and arrives from there Via the dampening roller 7 to the printing form 8. The dampening solution is metered, on the one hand, by varying the slip between the metering roller 6 and the dampening roller 7. The distribution cylinder 10 has the task of adding dampening solution particles (in particular water) to the ink on the dampening roller (not shown) ) Incorporate inking unit. This ink comes from the printing form 8 and possibly from an intermediate roller which is in contact with an inking roller and the dampening roller 7. In this respect, the intermediate roller forms a connecting link between the dampening unit 1 and the inking unit (not shown).

Erfindungsgemäß ist eine Gummierungseinrichtung 11 vorgesehen, die eine Gummierungs-Tauchwalze 12 aufweist, welche in eine mit Gummierungsflüssigkeit 13 gefüllte Wanne 14 eintaucht.According to the invention, a gumming device 11 is provided which has a gumming dipping roller 12 which dips into a tub 14 filled with gumming liquid 13.

In der Fig. 1 nimmt die Walzenanordnung eine Stellung ein, in der auf die Druckform 8 eine Gummierung aufgebracht wird. Von der angetriebenen Gummierungs-Tauchwalze 12 gefördertes Gummierungsmittel 13 wird auf den Reibzylinder 10 und von dort auf die Feuchtauftragwalze-/ übertragen und gelangt dann auf die Druckplatte. Mithin werden dem Feuchtwerk 1 angehörende Walzen, nämlich die Feuchtauftragwalze 7 und der Reibzylinder 10 erfindungsgemäß für einen anderen, weiteren Zweck, nämlich das Gummieren der Druckform 8, verwendet. Es ist daher möglich, die Gummierung automatisch aufzutragen. Die Gummierung bildet eine Schutzschicht, die eine Korrosion usw. der Druckplatte verhindert.In Fig. 1, the roller arrangement assumes a position in which a rubber coating is applied to the printing form 8. Rubberizing agent 13 conveyed by the driven rubber-dipping roller 12 is transferred to the distribution cylinder 10 and from there to the dampening roller / and then reaches the printing plate. Accordingly, rollers belonging to the dampening unit 1, namely the dampening application roller 7 and the distribution cylinder 10, are used according to the invention for another, further purpose, namely the gumming of the printing form 8. It is therefore possible to apply the rubber coating automatically. The rubber coating forms a protective layer that prevents corrosion etc. of the printing plate.

Um sicherzustellen, daß während des Aufbringens der Gummierung möglichst wenig Feuchtmittel 3 zur Feuchtauftragwalze 7 übertragen wird, so daß keine Verwässerung der Gummierungsflüssigkeit 13 erfolgt und überdies zu gewährleisten, daß nur vernachlässigbare Gummierungsflüssigkeitsmengen zur Feuchtmittelliefereinrichtung 2 übertragen werden, wird die Feuchtmittel-Tauchwalze 5 und damit auch die Dosierwalze 6 auf eine sehr geringe Drehzahl eingestellte Ferner wird zur Erzielung oder Verstärkung des gleichen Effekts die Drehzahl der Dosierwalze mittels eines (nicht dargestellten) Feuchtwerkantriebs derart eingestellt, daß ein möglichst geringer Schlupf zwischen der Feuchtauftragwalze 7 und der Dosierwalze 6 besteht.To ensure that as little dampening solution 3 as possible is transferred to the dampening roller 7 during the application of the rubber coating, so that there is no watering down of the rubber coating liquid 13 and, moreover, to ensure that only negligible Gum amounts of liquid are transferred to the dampening solution delivery device 2, the dampening solution immersion roller 5 and thus also the metering roller 6 are set to a very low speed. Furthermore, to achieve or reinforce the same effect, the speed of the metering roller is set by means of a dampening drive (not shown) in such a way that a there is as little slip as possible between the dampening roller 7 and the metering roller 6.

Die Fig. 2 zeigt ein weiteres Ausführungsbeispiel, das sich gegenüber dem Ausführungsbeispiel der Fig. 1 darin unterscheided, daß die Gummierungseinrichtung 11 als Sprühvorrichtung 15 ausgebildet ist, die Gummierungsflüssigkeit auf die Feuchtauftragwalze 7 aufsprüht. Von dort wird dann die Gummierungsflüssigkeit 13 auf die Druckform 8 übertragen. Alternativ ist es auch möglich, daß die Sprüheinrichtung 15 eine Position einnimmt, in der ihr Sprühstrahl auf den Reibzylinder 10 trifft, der die Gummierungsflüssigkeit zur Feuchtauftragwalze 7 überträgt. Auch beim Ausführungsbeispiel der Fig. 2 werden Drehzahl und Schlupf der Dosierwalze 6 - wie oben erwähnt - zur Vermeidung eines Verwässern der Gummierungsflüssigkeit in entsprechender Weise eingestellt.FIG. 2 shows a further exemplary embodiment, which differs from the exemplary embodiment of FIG. 1 in that the gumming device 11 is designed as a spray device 15 which sprays the gumming liquid onto the dampening roller 7. From there, the gumming liquid 13 is then transferred to the printing form 8. Alternatively, it is also possible for the spray device 15 to assume a position in which its spray jet strikes the distribution cylinder 10, which transfers the gumming liquid to the dampening roller 7. Also in the embodiment of FIG. 2, the speed and slip of the metering roller 6 - as mentioned above - are set in a corresponding manner to avoid watering down of the gumming liquid.

Alternativ zum Ausführungsbeispiel der Fig. 1 ist es jedoch auch möglich, mittels einer (nicht dargestellten) Trenneinrichtung die Dosierwalze 6 von der Feuchtauftragwalze 7 abzustellen, so daß im Gummierungsbetrieb keine Gummierungsflüssigkeit in die Feuchtmittelliefereinrichtung 2 bzw. Feuchtmittel 3 in die Gummierungsflüssigkeit 13 eintreten kann.As an alternative to the exemplary embodiment in FIG. 1, however, it is also possible to switch off the metering roller 6 from the dampening application roller 7 by means of a separating device (not shown), so that no gumming liquid can enter the dampening solution delivery device 2 or dampening solution 3 into the gumming liquid 13 in the gumming operation.

Die Abstandsstellung zwischen Feuchtauftragwalze 7 und Dosierwalze 6 ist selbstverständlich auch beim Ausführungsbeispiel der Fig. 2 realisierbar, um auch dort die gewünschten Effekte zu erzielen.The distance between the dampening roller 7 and the metering roller 6 is of course also Embodiment of FIG. 2 realizable to achieve the desired effects there.

Soll die Gummierung wieder von der Druckform 8 entfernt werden, so wird diese mittels einer (nicht dargestellten) Waschvorrichtung gewaschen. Bei diesem Waschvorgang ist gemäß Fig. 4 vorgesehen, daß die Feuchtauftragwalze 7 ihre Anlagestellung an den Plattenzylinder 9 einnimmt. Hierdurch gelangt die Waschflüssigkeit ebenfalls zur Feuchtauftragwalze 7 und von dort auch zum Reibzylinder 10 (sofern dieser vorhanden ist). Um zu verhindern, daß die Waschflüssigkeit zur Feuchtmittelliefereinrichtung 2 und/oder zur Gummierungseinrichtung 11 gelangt, wird mit der Trenneinrichtung eine Abstandsstellung zwischen der Feuchtauftragwalze 7 und der Dosierwalze 8 herbeigeführt sowie die Gummierungseinrichtung 11 derart verlagert, daß der Reibzylinder 10 keinen Kontakt mehr zur Gummierungs-Tauchwalze 12 hat. In der beschriebenen Stellung der Walzenanordnung wird daher nicht nur die Druckform 8 gewaschen, sondern es wird auch die Feuchtauftragwalze 7 und der Reibzylinder 10 von Gummierungsresten befreit. In gleicher Weise läßt sich nach einem Druckvorgang auch die Farbe von der Feuchtwalze abwaschen.If the rubber coating is to be removed again from the printing form 8, it is washed by means of a washing device (not shown). 4, the dampening roller 7 assumes its bearing position on the plate cylinder 9. As a result, the washing liquid also reaches the dampening roller 7 and from there also to the distribution cylinder 10 (if it is present). In order to prevent the washing liquid from reaching the dampening agent delivery device 2 and / or the gumming device 11, the separating device brings about a spacing position between the dampening applicator roll 7 and the metering roll 8 and the gumming device 11 is displaced such that the distribution cylinder 10 no longer has any contact with the gumming device. Dip roller 12 has. In the position of the roller arrangement described, not only is the printing plate 8 washed, but the dampening roller 7 and the distribution cylinder 10 are also freed of gum residues. In the same way, the ink can also be washed off the dampening roller after a printing operation.

Die erfindungsgemäße Lehre erlaubt daher das automatische Gummieren der Druckform 8 sowie die Reinigung der Druckform 8 und der zur Gummierung verwendeten Bauteile der Offsetdruckmaschine. Die erfindungsgemäße Lehre erfaßt selbstverständlich auch den Fall, daß die Gummierungs-Tauchwalze 12 nicht unter Zwischenschaltung des Reibzylinders 10 auf die Feuchtauftragwalze 7 wirkt, sondern eine direkte Kontaktstellung zu letzterer einnimmt.The teaching according to the invention therefore allows the automatic gumming of the printing form 8 and the cleaning of the printing form 8 and the components of the offset printing machine used for gumming. The teaching according to the invention naturally also covers the case in which the rubber plunging roller 12 does not act on the dampening roller 7 with the interposition of the distribution cylinder 10, but instead assumes a direct contact position with the latter.
