Description

Die Erfindung betrifft ein Feuchtwerk für eine Offsetdruckmaschine mit einer Dosierwalze, einer Auftragwalze zum Auftrag von Feuchtmittel auf einen Plattenzylinder, einer unter gegenseitiger Pressung der Dosierwalze und der Auftragwalze gebildeten Kontaktzone entlang sich berührender achsparalleler Mantellinien dieser Walzen, Antriebsmitteln zur Drehung der Dosierwalze und der Auftragwalze mit im Bereich der Kontaktzone im wesentlichen nach unten weisender Richtung der Umfangsgeschwindigkeiten dieser Walzen, einem oberhalb der Kontaktzone befindlichen, von den Mantelflächen der Dosierwalze und der Auftragwalze und von Abdichtmitteln an den Enden dieser Walzen gebildeten Vorratsraum für Feuchtmittel und einer mit einer Walzenoberfläche zusammenarbeitenden traversierenden Reibwalze.The invention relates to a dampening system for an offset printing machine with a metering roller, an application roller for applying dampening solution to a plate cylinder, a contact zone formed by mutual pressing of the metering roller and the application roller along axially parallel surface lines of these rollers, drive means for rotating the metering roller and the application roller in the area of the contact zone essentially pointing downward in the direction of the peripheral speeds of these rollers, a storage space for dampening solution located above the contact zone, formed by the lateral surfaces of the metering roller and the application roller and by sealing means at the ends of these rollers, and a traversing friction roller which cooperates with a roller surface.

Ein derartiges Feuchtwerk ist aus der DE-OS 22 06 498 bekannt. Hierbei ist eine oszillierende Reibwalze vorgesehen, die an der Auftragwalze zwischen deren Kontaktstelle mit dem Plattenzylinder und dem Vorratsraum für Feuchtmittel im Zwickel zwischen der Auftragwalze und einer daran angestellten Dosierwalze angeordnet ist.Such a dampening system is known from DE-OS 22 06 498. Here, an oscillating friction roller is provided, which is arranged on the applicator roller between its contact point with the plate cylinder and the reservoir for dampening solution in the gusset between the applicator roller and a metering roller attached to it.

In jüngerer Zeit wurde bei ähnlichen Feuchtwerkssystemen auf eine an sich wünschenswerte Verreibung verzichtet, um einen ungehinderten Rücktransport von überschüssigem Feuchtmittel vom Plattenzylinder zum Vorratsraum zu ermöglichen (siehe US-PS 4,455,938).More recently, a similarly desirable dampening system has been dispensed with in the case of similar dampening system in order to enable unhindered return of excess dampening solution from the plate cylinder to the storage space (see US Pat. No. 4,455,938).

Die Aufgabe der vorliegenden Erfindung besteht darin, ein gattungsgemäßes Feuchtwerk vorzuschlagen, mit dem sowohl eine Verreibung als auch ein ungehinderter Rücktransport von überschüssigem Feuchtmittel vom Plattenzylinder zum Vorratsraum für Feuchtmittel möglich ist.The object of the present invention is to propose a generic dampening system with which both a rubbing and an unhindered return transport of excess dampening solution from the plate cylinder to the storage space for dampening solution is possible.

Diese Aufgabe wird gelöst mit einem Feuchtwerk gemäß Anspruch 1.This object is achieved with a dampening unit according to claim 1.

Die erfindungsgemäße Anordnung der Reibwalze wirkt sowohl dem sogenannten Schabloniereffekt als auch einem linienförmigen Überfeuchten entgegen.The arrangement of the friction roller according to the invention counteracts both the so-called stenciling effect and a linear over-moistening.

Durch diese Anordnung der Reibwalze muß der Vorteil ihrer vergleichmäßigenden Wirkung nicht durch einen anderen störenden Einfluß erkauft werden, der bei bekannten gattungsgemäßen Feuchtwerken dadurch erwächst, daß die Mantelfläche der Auftragwalze auf ihrem Weg vom Plattenzylinder zum Vorratsraum für das Feuchtmittel von einer Reibwalze kontaktiert wird, wodurch ein ungehinderter Feuchtmittelrücktransport vom Plattenzylinder zum Vorratsraum für das Feuchtmittel gestört werden kann.With this arrangement of the distribution roller, the advantage of its comparative effect does not have to be bought through another disruptive influence which arises in known dampening units of the generic type in that the outer surface of the application roller is contacted by a distribution roller on its way from the plate cylinder to the reservoir for the dampening solution, whereby an unhindered return of dampening solution from the plate cylinder to the storage area for the dampening solution can be disturbed.

Ein sicherer Antrieb der Reibwalze wird durch formschlüssige Antriebsmittel für die Dosierwalze gewährleistet.A secure drive of the distribution roller is guaranteed by positive drive means for the metering roller.

Überdies hat die erfindungsgemäße Anordnung der Reibwalze auch den Vorteil, daß eine ungestörte Übertragung des in der Kontaktzone gebildeten Feuchtmittelfilms auf den Plattenzylinder erfolgen kann.In addition, the arrangement of the friction roller according to the invention also has the advantage that an undisturbed transfer of the dampening solution film formed in the contact zone to the plate cylinder can take place.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.In the drawing, an embodiment of the invention is shown schematically.

Das an einen Plattenzylinder 2 angestellte Feuchtwerk 1 umfaßt eine Dosierwalze 3, eine Auftragwalze 4 für das Feuchtmittel und eine Reibwalze 5. Die Welle 6 der Dosierwalze 3 ist beiderseits in ortsfesten Lagerungen der Maschine aufgenommen. An den Stirnseiten der Dosierwalze 3 ist je eine Lagerplatte 7 auf je einem Wellenzapfen der Welle 6 um diese schwenkbar angeordnet. Die beiden Lagerplatten 7 sind mittels Traversen 8 miteinander verbunden. Die Auftragwalze 4 ist mit ihren Enden in je einem Gleitschuh 9 gelagert, der seinerseits an in die Lagerplatten 7 eingearbeiteten geradlinigen Führungsflächen 10 gleitet. Diese Führungsflächen 10 sind im wesentlichen parallel zu der Richtung einer Tangente an den Plattenzylinder 2 in einem Berührungspunkt mit der Auftragwalze 4. Der jeweilige Gleitschuh 9 ist mit einem am freien Ende mit Gewinde versehenen Schaft 11 verbunden, der in Richtung der Führungsflächen 10 verläuft und von der jeweiligen Lagerplatte 7 geführt ist. Je eine an der Lagerplatte 7 abgestützte Druckfeder 12 beaufschlagt den jeweiligen Gleitschuh 9 in Richtung "Lösen des Kontakts mit der Dosierwalze". Der Schaft 11 durchdringt weiterhin eine Aussparung 13 in der jeweiligen Lagerplatte 7, in der jeweils ein Stellantrieb für den jeweiligen Gleitschuh 9 vorgesehen ist. Der jeweilige Stellantrieb ist gebildet aus einer gleitbar auf dem Schaft 11 angeordneten und gegen eine auf das Gewinde des Schaftes 11 aufgeschraubte Stellhülse 18 angestellten Zahnstange 17 und einem (nicht dargestellten) mit der Zahnstange 17 kämmenden und mit einem Schneckenrad 16 koaxialen Zahnrad. Die (nicht dargestellten) Zahnräder zur Verstellung der jeweiligen Zahnstange 17 sind gemeinsam auf einer Stellwelle 19 befestigt. Auf dieser Stellwelle 19 ist weiterhin das mit einer Schnecke 15 in Eingriff stehende Schneckenrad 16 befestigt, so daß die Stellwelle 19 mittels eines an der Schnecke 15 angeordneten Betätigungsteils 14 verdrehbar ist.The dampening unit 1 employed on a plate cylinder 2 comprises a metering roller 3, an applicator roller 4 for the dampening solution and a friction roller 5. The shaft 6 of the metering roller 3 is accommodated on both sides in stationary bearings of the machine. On the end faces of the metering roller 3, a bearing plate 7 is arranged on each shaft journal of the shaft 6 so as to be pivotable about the latter. The two Bearing plates 7 are connected to one another by means of crossbeams 8. The applicator roller 4 is supported with its ends in a slide shoe 9, which in turn slides on straight guide surfaces 10 incorporated into the bearing plates 7. These guide surfaces 10 are substantially parallel to the direction of a tangent to the plate cylinder 2 at a point of contact with the application roller 4. The respective slide shoe 9 is connected to a shaft 11 which is threaded at the free end and runs in the direction of the guide surfaces 10 and from the respective bearing plate 7 is guided. A compression spring 12 supported on the bearing plate 7 acts on the respective sliding shoe 9 in the direction of “releasing the contact with the metering roller”. The shaft 11 also penetrates a recess 13 in the respective bearing plate 7, in each of which an actuator for the respective sliding block 9 is provided. The respective actuator is formed from a slidably arranged on the shaft 11 and against a screwed onto the thread of the shaft 11 an adjusting sleeve 18 and a rack 17 (not shown) meshing with the rack 17 and 16 coaxial with a worm gear. The gearwheels (not shown) for adjusting the respective toothed rack 17 are fastened together on an adjusting shaft 19. The worm wheel 16, which is in engagement with a worm 15, is also fastened on this adjusting shaft 19, so that the adjusting shaft 19 can be rotated by means of an actuating part 14 arranged on the worm 15.

Im oberen Zwickel zwischen der Dosierwalze 3 und der Auftragwalze 4 befindet sich das Feuchtmittel, das hierin durch geeignete(nicht dargestellte) Abdichtmittel an den Stirnseiten dieser Walzen eingeschlossen ist. Eine durch die gegenseitige Pressung dieser Walzen mit Hilfe des Betätigungsteils 14 einstellbare Feuchtmittelmenge wird durch die Kontaktzone 20 dieser Walzen über die unter der Kontaktzone 20 befindliche Mantelfläche der Auftragwalze 4 zum Plattenzylinder 2 befördert. Hierzu besitzt das Feuchtwerk Antriebsmittel 21, 22 zur Drehung der Dosierwalze 3 und der Auftragwalze 4 mit im Bereich der Kontaktzone 20 nach unten weisender Richtung der Umfangsgeschwindigkeiten dieser Walzen. Diese Antriebsmittel treiben die Dosierwalze 3 mit der Umfangsgeschwindigkeit des Plattenzylinders 2 an. Dies geschieht über ein Triebrad 21 eines Zahnräderzuges der Druckmaschine, das mit einem Zahnrad 22 kämmt, welches koaxial zur Dosierwalze 3 angeordnet und mit dieser über einen (nicht dargestellten) Freilauf verbunden ist.In the upper gusset between the metering roller 3 and the applicator roller 4 is the dampening solution, which is enclosed here by suitable (not shown) sealing means on the end faces of these rollers. An adjustable amount of dampening solution by the mutual pressing of these rollers with the aid of the actuating part 14 is through the contact zone 20 of these rollers on the under Contact zone 20 located outer surface of the applicator roller 4 is conveyed to the plate cylinder 2. For this purpose, the dampening unit has drive means 21, 22 for rotating the metering roller 3 and the applicator roller 4 with the circumferential speeds of these rollers pointing downward in the region of the contact zone 20. These drive means drive the metering roller 3 at the peripheral speed of the plate cylinder 2. This takes place via a drive wheel 21 of a gear train of the printing press, which meshes with a gear 22 which is arranged coaxially with the metering roller 3 and is connected to the latter via a freewheel (not shown).

Die Auftragwalze 4 wird durch die Dosierwalze 3 über Friktion in der Kontaktzone 20 angetrieben.The application roller 4 is driven by the metering roller 3 via friction in the contact zone 20.

Gegenüber der Kontaktzone 20 ist an die Dosierwalze 3 eine traversierende Reibwalze 5 angestellt, deren Drehung und Traversierung durch Friktion an der Dosierwalze 3 bewerkstelligt wird. Hierzu ist die Achse 23 der Reibwalze 5 mit ihren Enden drehfest in je einem Langloch 24 der jeweiligen Lagerplatte 7 aufgenommen. Das Langloch 24 erstreckt sich im wesentlichen in Richtung auf die Dosierwalze 3 hin und ist in seiner Breite an den Durchmesser der Achse 23 angepaßt. Innerhalb dieses Langloches 24 ist diese Achse 23 jeweils mit einer in die Lagerplatte 7 eingeschraubten Stellschraube 25 befestigt, welche die Achse 23 auf eine gegenüber der Stellschraube in der Lagerplatte 7 angeordnete Druckfeder 26 andrückt.Compared to the contact zone 20, a traversing friction roller 5 is set on the metering roller 3, the rotation and traversing of which is accomplished by friction on the metering roller 3. For this purpose, the ends of the axis 23 of the friction roller 5 are rotatably received in an elongated hole 24 of the respective bearing plate 7. The elongated hole 24 extends essentially in the direction of the metering roller 3 and its width is adapted to the diameter of the axis 23. Within this elongated hole 24, this axis 23 is in each case fastened with an adjusting screw 25 screwed into the bearing plate 7, which presses the axis 23 onto a compression spring 26 arranged in relation to the adjusting screw in the bearing plate 7.
