Description

Die Erfindung betrifft ein Wälzelement zum Andrücken einer flexiblen Druckplatte an den Formzylinder eines Druckwerkes einer Rotationsdruckmaschine beim Plattenwechsel nach dem Oberbegriff des Patentanspruchs 1 oder 6.The invention relates to a rolling element for pressing a flexible Printing plate on the form cylinder of a printing unit Rotary printing machine when changing plates according to the generic term of Claim 1 or 6.

Das JP-Schutzrecht 1-176558 zeigt eine Vorrichtung zur Montage und Demontage einer flexiblen Druckplatte. Beim Wickeln der Druckplatte auf den oder von dem Formzylinder bedient sich die Vorrichtung zweier Rollen, mit denen die Druckplatte gegen den sich drehenden Formzylinder gedrückt wird. Die Rollen sind zueinander beabstandet und werden von jeweils einem Arbeitszylinder angestellt, an deren Kolbenstangen sie drehbar befestigt sind. Bei dieser Vorrichtung ist nachteilig, daß die Rollen bei der Demontage einer Druckplatte von deren eingefärbtem Bild mit Druckfarbe verschmiert werden. Vor dem Montieren einer neuen Druckplatte müssen die Rollen zeitaufwendig gesäubert werden. Anderenfalls verschmieren die Rollen die neue Druckplatte, und als Folge dessen fällt beim Druckbeginn Makulatur an, bis sich die Druckplatte beim Drucken säubert.The JP property right 1-176558 shows a device for assembly and Disassembly of a flexible pressure plate. When winding the pressure plate the device uses or on the forme cylinder two rollers with which the pressure plate against the rotating Forme cylinder is pressed. The rollers are spaced apart and are employed by one working cylinder at the other Piston rods they are rotatably attached. In this device is disadvantageous that the roles when dismantling a printing plate of whose colored image is smeared with printing ink. Before the Assembling a new pressure plate means the rollers are time consuming to be cleaned. Otherwise the rollers will smear the new one Printing plate, and as a result, paper waste falls at the start of printing until the printing plate cleans itself during printing.

Bei einer stationär am Formzylinder angeordneten Andrückrolle (DE 42 18 602 C2) besteht weiterhin die Gefahr, daß die Andrückrolle durch Farbspritzer und Farbnebeln verschmutzt wird. Bei der Montage einer neuen Druckplatte stellen sich dann ebenfalls die aufgezeigten Nachteile ein.In the case of a pressure roller arranged stationary on the forme cylinder (DE 42 18 602 C2) there is still the danger that the pressure roller will Paint splatter and paint mist is dirty. When assembling one new printing plate then also face those shown Disadvantages.

Es ist Aufgabe der Erfindung, ein Wälzelement zum Andrücken der Druckplatte zu schaffen, das die Druckplatte bei deren Montage nicht mit Farbe verschmiert. It is an object of the invention to provide a rolling element for pressing To create pressure plate that the pressure plate is not when it is assembled smeared with paint.

Erfindungsgemäß wird diese Aufgabe bei einer gattungsgemäßen Vorrichtung durch die Anwendung der Merkmale des Kennzeichens des Patentanspruchs 1 gelöst. Durch die Trennung des Wälzelements in erste und zweite Rollen werden die lediglich bei der Druckplattenmontage verwendeten ersten Rollen bei einer Druckplattendemontage nicht mit Farbe verschmiert und verschmutzen so nicht die neue Druckplatte. Maschinenstillstandszeiten sparend braucht nicht mehr laufend das Wälzelement gewaschen zu werden, und für diesen Vorteil muß keine Makulatur in Kauf genommen werden. In Verbindung mit einem geeigneten Plattenspannsystem eröffnet das Wälzelement die Möglichkeit eines vollautomatischen Plattenwechsels.According to the invention, this object is achieved with a generic Device through the application of the characteristics of the mark of the Claim 1 solved. By separating the rolling element in first and second roles are only in the Printing plate assembly used the first roles in a Pressure plate disassembly not smeared with paint and dirty not the new printing plate. Saves machine downtimes the rolling element no longer needs to be washed continuously, and no waste has to be accepted for this advantage. This opens up in connection with a suitable plate clamping system Rolling element the possibility of a fully automatic plate change.

Die Aufgabe wird auch erfindungsgemäß mit den kennzeichnenden Merkmalen des Patentanspruchs 6 gelöst. Der Schmutzschutz vermeidet das Verschmutzen von Andrückelementen durch Farbspritzer und Farbnebeln und erspart deren Reinigen. Auch Rollen, die nur zur Montage einer Druckplatte verwendet werden und so ggf. stationär angeordnet sind und über die Breite der Druckplatte reichen, brauchen nunmehr keinen häufigen Reinigungen mehr unterzogen zu werden.The task is also inventively with the characteristic Features of claim 6 solved. The dirt protection avoids the soiling of pressure elements by paint splashes and Color mist and saves you having to clean it. Even roles that are only for Mounting a pressure plate can be used and so stationary if necessary are arranged and extend across the width of the printing plate, no longer need to be subjected to frequent cleaning become.

1 shows a printing unit of an offset rotary printing machine with the printing units 1 and 2. Each printing unit 1, 2 contains a forme cylinder 3, 4 and a transfer cylinder 5, 6. On the forme cylinder 3 there are rolling elements in the form of first and second rollers 7, 8 arranged (Fig. 2), namely the first and second rollers 7, 8 are alternately arranged side by side. In each case two rollers 7 are rotatably mounted on an axis 10 which is fastened to the piston rod 11 of a working cylinder 12. Similarly, two rollers 8 are each rotatably mounted on an axis 22 which is fastened to the piston rod 23 of a working cylinder 24. The working cylinders 12 and 24 are arranged on a crossmember 13 which is fastened to a roller guard 15 which is pivotably mounted in the side walls 14 of the printing unit 1. By pivoting the roller guard 15 about its pivot point 34 into the position shown in broken lines in FIG. 1, the rollers 7, 8 are thus simultaneously pivoted away from the forme cylinder 3, the latter being easily accessible. Dispensing with this possibility of exposing the forme cylinder 3, the cross member 13 can also be fixedly attached to the side walls 14.

Die Rollen 7, 8 haben einen Gummi- oder anderweitigen elastischen Belag, damit sie bei der Anlage an der Druckplatte diese nicht beschädigen. Die Ausführung kann auch dahingehend geändert sein, daß an einer Kolbenstange 11, 23 nur eine, ggf. breitere Rolle angeordnet wird. Im Grenzfall kann auch nur eine einzige erste Rolle zum Einsatz kommen, die etwa über eine Hälfte der Druckplatte reicht, während eine einzige zweite Rolle im Bereich der anderen Hälfte der Druckplatte anstellbar ist. The rollers 7, 8 have a rubber or other elastic Covering so that they do not attach to the printing plate to damage. The design can also be changed so that only one, possibly wider, roller on a piston rod 11, 23 is arranged. In the borderline case, only one can be used Roll are used, which is about half of the printing plate ranges while a single second role in the other Half of the pressure plate is adjustable.

Die Rollen 7 und 8 mitsamt den Arbeitszylindern 12 und 24 und der Traverse 13 sind in einem Schmutzschutz 16 untergebracht. Letzterer ist kastenförmig ausgebildet und weist zum Formzylinder 3 hin eine schwenkbare Öffnungsklappe 17 auf. Am Schmutzschutz 16, genauer gesagt an der Traverse 13, ist ein Arbeitszylinder 18 befestigt, dessen Kolbenstange 19 über eine Koppel 20 gelenkig mit der Öffnungsklappe 17 zu deren Betätigung verbunden ist (Fig. 7).The rollers 7 and 8 together with the working cylinders 12 and 24 and the Traverse 13 are housed in a dirt protection 16. The latter is box-shaped and points towards the forme cylinder 3 pivotable opening flap 17. On dirt protection 16, more precisely said on the traverse 13, a working cylinder 18 is attached, whose piston rod 19 is articulated via a coupling 20 with the Opening flap 17 is connected to its actuation (Fig. 7).

Zur Montage der Druckplatte 25 wird diese zunächst mit ihrem vorlaufenden Ende an den Spannkanal 26 an den Formzylinder 3 herangeführt. Anschließend wird der Arbeitszylinder 18 umgesteuert und seine Kolbenstange 19 herausgefahren. Diese schwenkt dabei über die Koppel 20 die Öffnungsklappe 17 in die in Fig. 4 gezeichnete Öffnungstellung (Öffnungsstellung ist in Fig. 7 strichpunktiert gezeichnet). Danach werden durch Umsteuern der Arbeitszylinder 12 deren Kolbenstangen 11 herausgefahren und dadurch die Rollen 7 an den Formzylinder 3 angestellt. Die Rollen 7 klemmen nun die Vorderkante der Druckplatte 25. Beim anschließenden Drehen des Formzylinders 3 in der angegebenen Richtung (Fig. 4 und 5) wird die Druckplatte 25 auf den Formzylinder 3 aufgezogen. Sie wird dabei von der Bürstenwalze 27 gestützt. Außerdem wird durch den mit großen Radien gerundeten Walzenschutz 15 verhindert, daß sich das nachlaufende Ende der Druckplatte 25 verhakt. Beim Aufziehen der Druckplatte 25 stehen die Rollen 7 mit dem Formzylinder 3 in Rollkontakt und drücken die Druckplatte 25 an den Formzylinder 3 an. Die geöffnete Öffnungsklappe 17 dient dabei als Einlaufschutz für den Einlaufspalt 28 zwischen Formzylinder 3 und Rolle 7. Beim Aufziehen der Druckplatte ist von Vorteil, daß die Anlage des Übertragungszylinders 5 am Formzylinder 3 nicht benötigt wird. Statt dessen befindet sich der Übertragungszylinder 5 in der Druckabstellung, so daß bei einem Plattenwechsel, also sowohl bei der Plattenmontage, wie auch bei der weiter unten beschriebenen Plattendemontage die später zu bedruckende Bahn 29 nicht gekappt zu werden braucht. To assemble the pressure plate 25, this is first with your leading end to the clamping channel 26 to the forme cylinder 3 introduced. Then the working cylinder 18 is reversed and extended its piston rod 19. This swings over the coupling 20, the opening flap 17 into that shown in FIG. 4 Open position (open position is dash-dotted in Fig. 7 drawn). Then, by reversing the working cylinder 12 the piston rods 11 moved out and thereby the rollers 7 on the forme cylinder 3 employed. The rollers 7 now clamp the Front edge of the pressure plate 25. When turning the Forme cylinder 3 in the specified direction (Fig. 4 and 5) Pressure plate 25 mounted on the plate cylinder 3. It is from the brush roller 27 supported. In addition, the large Radius rounded roller guard 15 prevents that trailing end of the pressure plate 25 hooked. When winding up the Pressure plate 25, the rollers 7 with the forme cylinder 3 in Roll contact and press the pressure plate 25 to the plate cylinder 3. The open opening flap 17 serves as a run-in protection for the inlet gap 28 between forme cylinder 3 and roller 7. At Pulling up the pressure plate is advantageous that the system of the Transfer cylinder 5 on the forme cylinder 3 is not required. Instead of which is the transfer cylinder 5 in the Print shutdown, so that when changing plates, i.e. both plate mounting, as also described below Disassembly of the plate does not cut the web 29 to be printed later are needed.

In Fig. 6 ist die Demontage der Druckplatte 25 gezeigt. Die Öffnungsklappe 17 des Schmutzschutzes 16 befindet sich durch entsprechendes Ansteuern des Arbeitszylinders 18 bereits in der Öffnungsstellung. Durch Umsteuern der Arbeitszylinder 24 werden deren Kolbenstangen 23 aus der in Fig. 2 gezeigten Stellung in die in Fig. 6 gezeichnete Stellung gebracht, d. h. ausgefahren. Dadurch werden die Rollen 8 an den Formzylinder 3 herangefahren und liefern zu diesem den Abrollkontakt beim Abwickeln der Druckplatte 25. Es kommen also lediglich diese Rollen 8 mit der eingefärbten, zu demontierenden Druckplatte 25 in Kontakt und werden mit Farbe beschmutzt. Für die Montage einer neuen, sauberen Druckplatte 25 stehen dann wieder die sauberen Rollen 7 zur Verfügung.6 shows the disassembly of the pressure plate 25. The Opening flap 17 of the dirt protection 16 is through appropriate control of the working cylinder 18 already in the Open position. By reversing the working cylinder 24 whose piston rods 23 from the position shown in Fig. 2 in the brought in position shown in Fig. 6, d. H. extended. Thereby the rollers 8 are moved up to the forme cylinder 3 and deliver to this the rolling contact when unwinding the pressure plate 25. It So only these rolls 8 come with the colored one disassembling printing plate 25 in contact and be with paint soiled. For the assembly of a new, clean pressure plate 25 the clean rollers 7 are then available again.

Ein weiteres Wälzelement mit ersten und zweiten Rollen 7, 8 ist am Formzylinder 4 des unteren Druckwerkes 2 angeordnet. Die Befestigung der Rollen 7, 8 erfolgt am Walzenschutz 30, der im Schwenkpunkt 31 in den Seitenwänden 14 gelagert ist. Somit sind die ersten und zweiten Rollen 7, 8 zusammen mit dem Walzenschutz 30 um den Schwenkpunkt 31 vom Formzylinder 4 wegschwenkbar (strichpunktiert gezeichnete Lage in Fig. 1).Another rolling element with first and second rollers 7, 8 is on Form cylinder 4 of the lower printing unit 2 arranged. The attachment the rollers 7, 8 take place on the roller guard 30, which is at the pivot point 31 is stored in the side walls 14. So the first and second rollers 7, 8 together with the roller guard 30 around the Pivot point 31 can be pivoted away from the forme cylinder 4 (dash-dotted lines drawn position in Fig. 1).

Die Arbeitszylinder 12, 18 und 24 werden vorteilhaft mit Druckluft betrieben. Dabei ist die Druckluft für den Arbeitszylinder 18 hinsichtlich ihres Druckes so begrenzt, daß die betätigte Öffnungsklappe 17 beim Öffnen oder Schließen die Hände einer Bedienperson nicht verletzt.The working cylinders 12, 18 and 24 are advantageously with compressed air operated. The compressed air for the working cylinder is 18th limited in pressure so that the operated Opening flap 17 when opening or closing the hands of one Operator not injured.

Das Plattenspannsystem der Formzylinder 3, 4 selbst mitsamt der zugehörigen Betätigungselemente 32, 33 wird nicht beschrieben, da dies nicht Gegenstand der Erfindung ist.The plate clamping system of the forme cylinders 3, 4 together with the associated actuators 32, 33 is not described because this is not the subject of the invention.
