Description

Die Erfindung bezieht sich auf einen Antrieb für Farbreiber im Farbwerk von Rotationsdruckmaschinen, bei welchem die Antriebseinleitung ausgehend von einem Druckwerkzylinder erfolgt und mindestens ein Reibzylinder im Farbwerk angeordnet ist, welcher eine seitliche, verreibende Bewegung ausführt.The invention relates to a drive for ink rubbers in the inking unit of rotary printing presses, in which the drive is initiated from a printing unit cylinder and at least one distribution cylinder is arranged in the inking unit, which carries out a lateral, rubbing movement.

Aus dem Stande der Technik, DE 28 08 856 C2 ist ein Farbwerkantrieb bekannt, bei dem die Einleitung des Antriebes an zwei Einleitungsstellen erfolgt. Dazu wird der obere Teil eines Farbwerkes durch eine vertikal eingebaute Längswelle und ein Kegelradgetriebe angetrieben, während der Antrieb im unteren Teil des Druckwerkes über ein Doppelkegelradgetriebe eingeleitet wird. Die Antriebsentkopplung zwischen einer Farbübertragungswalze im oberen Farbwerkteil und einer Verreibwalze im unteren Farbwerkteil bedingt demnach den Einsatz zweier Kegelradgetriebe einer zusätzlichen Antriebswelle sowie eine Synchronisation beider Antriebsstränge zueinander.An inking unit drive is known from the prior art, DE 28 08 856 C2, in which the drive is initiated at two introduction points. For this purpose, the upper part of an inking unit is driven by a vertically installed longitudinal shaft and a bevel gear, while the drive in the lower part of the printing unit is initiated by a double bevel gear. The decoupling of the drive between an ink transfer roller in the upper inking unit part and a distribution roller in the lower inking unit part therefore requires the use of two bevel gear units of an additional drive shaft and a synchronization of both drive trains with respect to one another.

US 3,118,373 offenbart einen Verreibwalzenantrieb an einer Druckmaschine. Bei dieser Vorrichtung des Standes der Technik erfolgt der Antrieb eines Zentralrades, mit dem wiederum die einzelnen Reibzylinder angetrieben werden, über eines der mit den Verreibwalzen changierenden Zahnräder. Über dieses changierende Zahnrad wird mithin die gesamte zum Antrieb der Reibwalzen erforderliche Antriebsleistung übertragen. Da dieses in Rede stehende Zahnrad zugleich translatorisch und rotatorisch beansprucht wird, ist es komplexen Beanspruchungszuständen ausgesetzt, die einen frühzeitigen Austausch dieses Zahnrades nach sich ziehen können.US 3,118,373 discloses a distributor roller drive on a printing press. In this device of the prior art, the drive of a central wheel, with which the individual distribution cylinders are in turn driven, takes place via one of the gearwheels which oscillate with the distribution rollers. The entire drive power required to drive the friction rollers is therefore transmitted via this oscillating gear. Since the gear in question is subjected to translational and rotational stresses at the same time, it is exposed to complex stress conditions which can result in the early replacement of this gear.

Durch die Erfindung werden die dem Stande der Technik anhaftenden Nachteile ausgeräumt.The disadvantages inherent in the prior art are eliminated by the invention.

Aufgabe der vorliegenden Erfindung ist es, Bauraum zu sparen sowie eine Reduzierung der Beanspruchung mechanischer Komponenten eines Antriebes für Farbreiber zu verwirklichen.The object of the present invention is to save installation space and to reduce the stress on mechanical components of a drive for ink rubbers.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß ein Reibzylinder antreibendes Zentralrad mit einem Zwischenrad in Eingriff steht, welches an einer exzentrisch zu einem Reibzylinder angeordneten Buchse gelagert ist.According to the invention, this object is achieved in that a central wheel driving a friction cylinder engages with an intermediate wheel which is mounted on a bushing arranged eccentrically to a distribution cylinder.

Von Vorteil bei dieser Lösung ist die Verlagerung des Kraftflusses von axial bewegten Reibzylinderzahnrädern auf ein axial festgelegtes Zwischenrad, wodurch die Bauteilbeanspruchung der Reibzylinderzahnräder entscheidend herabgesetzt wird. Durch die exzentrische Lagerung des Zwischenrades ist der zu überbrückende Abstand im Antriebsräderzug derart gestaltet, daß die axiale Verreibbewegung des Reibzylinders in keiner Weise eingeschränkt wird, die Beanspruchung des Reibzylinderzahnrades jedoch erheblich vermindert sind.The advantage of this solution is the shifting of the power flow from axially moving friction cylinder gearwheels to an axially fixed idler gear, as a result of which the stress on the components of the distribution cylinder gearwheels is significantly reduced. Due to the eccentric bearing of the idler gear, the distance to be bridged in the drive gear train is designed in such a way that the axial rubbing movement of the distribution cylinder is in no way restricted, but the stress on the distribution cylinder gear is considerably reduced.

In vorteilhafter Ausgestaltung des der Erfindung zugrunde liegenden Gedankens erstreckt sich ein Zapfen eines Reibzylinders durch eine Zwischenradbuchse. Dies ermöglicht unter optimaler Bauraumausnutzung die Plazierung eines den Kraftfluß übertragenden Zahnrades ohne Einschränkung der seitlichen Verreibbewegung. Ferner ist vorgesehen, daß der Durchmesser des Zwischenrades, welches axial festgelegt ist, den der Reibzylinderzahnräder der Reibzylinder übersteigt. Eine weitere vorteilhafte Ausgestaltung des der Erfindung zugrunde liegenden Gedankens liegt darin, daß ein bewegbares Rad mit dem Zwischenrad in Eingriff bringbar ist. Dadurch ergibt sich eine einzelne auskuppelbare Krafteinleitungsstelle für den Farbreiberantrieb.In an advantageous embodiment of the idea on which the invention is based, a journal of a distribution cylinder extends through an intermediate wheel bushing. This enables the placement of a gearwheel that transmits the power flow without restricting the lateral rubbing movement while making optimal use of the installation space. It is also provided that the diameter of the intermediate wheel, which is axially fixed, exceeds that of the distribution cylinder gears of the distribution cylinders. A further advantageous embodiment of the idea on which the invention is based is that a movable wheel can be brought into engagement with the intermediate wheel. Thereby there is a single disengageable force application point for the ink driver.

Weitere Merkmale der Erfindung können den weiteren Unteransprüchen entnommen werden.Further features of the invention can be found in the further subclaims.

In Fig. 1 ist ein schematisch dargestellter Querschnitt durch ein Druck- und Farbwerk dargestellt.1 shows a schematically represented cross section through a printing and inking unit.

Der Farbfluß in einem Farbwerk 1 erfolgt ausgehend von einem Farbkasten 2 über zwischen die einzelnen Farbwalzen geschaltete Reibzylinder 3, 4 und 5 an Auftragwalzen 7 und 8. Im hier gezeigten Farbwerk 1 sind einem Druckformzylinder 12 beispielsweise zwei Auftragwalzen 7 und eine weitere Auftragwalze 8 zugeordnet. Der durch besagte Auftragwalze 7 und 8 eingefärbte Druckformzylinder 12 färbt seinerseits einen Gummituchzylinder 13 ein, welcher wiederum mit seinem Gegenstück aus dem unteren Druckwerk eine durchlaufende Materialbahn beidseitig bedruckt. Am Reibzylinder 5 ist ein Reibzylinderzahnrad 10 befestigt, welches mit einem Zentralrad 11 kämmt. Die Reibzylinder 3 und 4 führen ebenfalls je ein Reibzylinderzahnrad 10; diese wurden jedoch aus Gründen der Übersichtlichkeit nicht dargestellt. Demnach werden die Reibzylinderzahnräder 10 aller Reibzylinder 3, 4, und 5 über das Zentralrad 11 angetrieben. Neben dem Reibzylinderzahnrad 10 befindet sich das Zentralrad 11 in Eingriff mit einem Zwischenrad 18, welches exzentrisch zum Reibzylinder 5 und dessen Reibzylinderzahnrad 10 angeordnet ist. Unterhalb des Zwischenrades 18 ist ein axial bewegbares Kupplungsrad 9 dargestellt, mit welchem ein Feuchtreiber antreibbar ist.The ink flow in an inking unit 1 takes place starting from an ink fountain 2 via distribution cylinders 3, 4 and 5 on application rollers 7 and 8 connected between the individual inking rollers. The printing form cylinder 12 inked by said application roller 7 and 8 in turn dyes a blanket cylinder 13, which in turn prints a continuous web of material on both sides with its counterpart from the lower printing unit. On the distribution cylinder 5, a distribution cylinder gear 10 is attached, which meshes with a central wheel 11. The distribution cylinders 3 and 4 also each have a distribution cylinder gear 10; however, these have not been shown for reasons of clarity. Accordingly, the distribution cylinder gears 10 of all distribution cylinders 3, 4 and 5 are driven via the central wheel 11. Next to the In the distribution cylinder gear 10, the central wheel 11 is in engagement with an intermediate wheel 18, which is arranged eccentrically to the distribution cylinder 5 and the distribution cylinder gear 10. Below the intermediate wheel 18, an axially movable clutch wheel 9 is shown, with which a wet driver can be driven.

Fig. 2 zeigt einen Längsschnitt, durch eine Reibzylinderlagerung oberhalb eines kuppelbaren Rades.Fig. 2 shows a longitudinal section through a distribution cylinder bearing above a detachable wheel.

An einer Seitenwand 14 eines Farbwerkes 1 ist mittels eines Hebels 17 ein in Wälzlagern 15 drehbar gelagertes Kupplungsrad 9 axial bewegbar angeordnet. Die Position der Wälzlager 15 wird durch Sicherungsringe 16 festgelegt.On a side wall 14 of an inking unit 1, a clutch wheel 9 rotatably mounted in roller bearings 15 is axially movable by means of a lever 17. The position of the roller bearings 15 is determined by circlips 16.

Oberhalb des Kupplungsrades 9 ist ein Zwischenrad 18 an einer Zwischenradbuchse 19 gelagert. Das Zwischenrad 18 ist als Zahnkranz ausgeführt und durch Lager 20 und 21 auf der Zwischenradbuchse 19 aufgenommen. Das Zwischenrad 18 wird in einer definierten Axialposition gehalten. Die Zwischenradbuchse 19 ist über mehrere Halteschrauben 26 mit einer Reiberlagerung 22 verschraubt und auf diese Weise an der Seitenwand 4 aufgenommen. Gegenüber dem innerhalb der Reiberlagerung 22 axial bewegbar gelagerten Reibzylinderzapfen 6 ist die Zwischenradbuchse 19 um eine Exzentrizität 25 versetzt angeordnet. Innerhalb der Reiberlagerung 22 sind zwei Dichtringe 24 angeordnet, die den mit einer Druckölzuleitung 23 in Verbindung stehenden Hohlraum an der Reiberlagerung 22 abdichten. An dem Reibzylinderzapfen 6 schließt sich der Walzenkörper des Reibzylinders 5 an, der jedoch nicht dargestellt ist. Am Reibzylinderzapfen 6 befindet sich das zum Antrieb des Reibwalzenkörpers dienende Reibzylinderzahnrad 10. Die Einleitung der axialen Verreibbewegung erfolgt über einen fliegend gelagerten Axialantrieb 27. Durch die im oberen Bereich des Reibzylinderzahnrades 10 markierten Doppelpfeile ist der Verreibhubbereich angedeutet.An intermediate gear 18 is mounted on an intermediate gear bushing 19 above the clutch gear 9. The idler gear 18 is designed as a ring gear and received by bearings 20 and 21 on the idler gear bushing 19. The intermediate wheel 18 is held in a defined axial position. The intermediate wheel bushing 19 is screwed to a friction bearing 22 via a plurality of retaining screws 26 and is thus received on the side wall 4. Compared to the friction cylinder journal 6, which is axially movably mounted within the friction bearing 22, the intermediate wheel bushing 19 is arranged offset by an eccentricity 25. Arranged within the friction bearing 22 are two sealing rings 24 which seal the cavity on the friction bearing 22 which is connected to a pressure oil supply line 23. The roller body of the distribution cylinder 5 adjoins the distribution cylinder journal 6, but is not shown. The distribution cylinder gear 10, which drives the distribution roller body, is located on the distribution cylinder journal 6. The axial rubbing movement is initiated via a floating axial drive 27 The area of the friction cylinder gear 10 marked double arrows indicates the displacement stroke area.

Sowohl das Zwischenrad 18, wie auch das Reibzylinderzahnrad 10 kämmen mit dem Zentralrad 11. Dabei verbleibt das Zentralrad 11 in ständigem Eingriff mit dem Zwischenrad 18. Das mit dem Kupplungsrad 9 - im eingekuppeltem Zustand - kämmende Zwischenrad 18 bildet demnach die Krafteinleitungsstelle für den Farbreiberantrieb. Das sich axial bewegende Reibzylinderzahnrad 10 des Reibzylinders 5 ist mithin entlastet. Die durch den Axialantrieb 27 erzeugte seitliche Verreibbewegung des Reibzylinders 5 kann deshalb vollständig ausgenutzt werden, weil die Nabe des Reibzylinderzahnrades 10 in eine vergrößert ausgeführte Bohrung 28 der Zwischenradbuchse 19 bei ihrer Bewegung auf die Seitenwand 14 zu, eintauchen kann und mithin die volle Breite des Zahnrades 11 ausgenutzt wird.Both the idler gear 18 and the friction cylinder gear 10 mesh with the central gear 11. The central gear 11 remains in constant engagement with the idler gear 18. The idler gear 18 meshing with the clutch gear 9 - in the engaged state - thus forms the force introduction point for the ink driver drive. The axially moving distribution cylinder gear 10 of the distribution cylinder 5 is therefore relieved. The lateral rubbing movement of the distribution cylinder 5 generated by the axial drive 27 can therefore be fully utilized because the hub of the distribution cylinder gear 10 can be immersed in an enlarged bore 28 of the intermediate gear bushing 19 as it moves towards the side wall 14 and thus the full width of the gear 11 is used.

Das Zentralrad 11 ist über Wälzlager auf einem an der Seitenwand 14 befestigten Zapfen gelagert. Die Zahnbreite des Zentralrades 11 ermöglicht zum einen eine stabile Kraftflußeinleitung über das exzentrisch gelagerte Zwischenrad 18 sowie den Antrieb der axial bewegbaren Reibzylinderräder 10. Durch Verwendung der exzentrisch gelagerten Zwischenradbuchse 19 kann der Antrieb des Zentralrades 11 durch ein im Durchmesser vergrößertes Zwischenrad 18 erfolgen, wodurch bei optimaler Bauraumausnutzung an der Seitenwand 14 die seitliche Verreibbewegung des Reibzylinders 5 nicht eingeschränkt ist.The central wheel 11 is mounted on roller bearings on a pin fastened to the side wall 14. The tooth width of the central wheel 11 enables a stable introduction of power flow via the eccentrically mounted intermediate gear 18 and the drive of the axially movable friction cylinder wheels 10. By using the eccentrically mounted intermediate gear bushing 19, the drive of the central gear 11 can be done by an enlarged intermediate gear 18, thereby at optimal use of space on the side wall 14, the lateral rubbing movement of the distribution cylinder 5 is not restricted.
