In this connection, the drive shaft (16, 18) of the distributing roller (1), which is mounted in lateral frames (7) of the rotary printing machine, has an articulated coupling (17). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum formschlüssigem rotativem und changierendem Antrieb von Farb- oder Feuchtwerkswalzen einer Rotationsdruckmaschine.The invention relates to a device for positive rotary and oscillating drive of inking or dampening unit rollers of a rotary printing press.

Die DE-OS 36 28 787 zeigt eine axial bewegbare Verreibwalze, die mit zwei Farbauftragwalzen in Verbindung steht. Die Verreibwalze ist zusammen mit den Farbauftragwalzen von einem Plattenzylinder abstellbar gelagert.DE-OS 36 28 787 shows an axially movable distributor roller, which is connected to two inking rollers. The distributing roller is supported by a plate cylinder, together with the inking rollers.

Ein Antrieb für die Verreibwalze ist nicht vorgesehen. Aus diesem Grund wird die Verreibwalze nur durch Friktion von den Farbauftragwalzen angetrieben. Bei einem Antrieb durch Friktion ist ein gewisser Schlupf zwischen den zusammenwirkenden Walzen jedoch nicht vermeidbar. Besonders auch bei Feuchtwerken ist ein Friktionsantrieb von Nachteil, weil bei erhöhten Feuchtmittelanteilen die Reibwerte zwischen den Walzen erheblich abnehmen. Insbesondere, wenn mehrere hintereinander angeordnete Walzen durch Friktion angetrieben werden, kann dies zu Einfärbeschwierigkeiten der Druckplatte wie Streifenbildung oder Punktverbreiterung führen.A drive for the distribution roller is not provided. For this reason, the distribution roller is only driven by friction from the inking rollers. When driven by friction, however, a certain slippage between the interacting rollers cannot be avoided. A friction drive is also a disadvantage, especially in dampening systems, because the friction coefficient between the rollers decreases considerably with increased dampening solution proportions. In particular, if several rollers arranged one behind the other are driven by friction, this can lead to difficulties in inking the printing plate, such as streaking or point widening.

Durch die US-PS 39 94 222 ist es bereits bekannt, Farbwalzen einer Rotationsdruckmaschine mit einem Rotations- und Changierantrieb zu versehen. Es ist jedoch nicht möglich, die Walzen außerdem noch ortsveränderlich, z. B. verschwenkbar zu lagern. Dies ist jedoch insbesondere dann notwendig, wenn die Reibwalze mit Farbauftragwalzen zusammenwirkt, welche z. B. bei einem Druckplattenwechsel vom Plattenzylinder abgestellt werden müssen.From US-PS 39 94 222 it is already known to provide inking rollers of a rotary printing press with a rotary and traversing drive. However, it is not possible the rollers can also be moved, e.g. B. pivotally. However, this is particularly necessary if the friction roller interacts with inking rollers, which, for. B. must be turned off when changing the printing plate from the plate cylinder.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Antrieb einer ortsveränderlichen Walze zu schaffen, die es ermöglicht, daß die Walze formschlüssig rotativ und changierend antreibbar ist.The invention has for its object to provide a device for driving a movable roller, which enables the roller to be driven in a form-fitting manner in rotation and oscillation.

Die Aufgabe wird erfindungsgemäß durch den kennzeichnenden Teil des Anspruchs 1 gelöst.The object is achieved by the characterizing part of claim 1.

Der Vorteil der Erfindung ist, daß die sowohl zum rotierenden als auch zum changierenden Antrieb vorgesehenen Mittel (z. B. Zahnräder) außerhalb der Seitengestelle angeordnet werden können, wodurch diese gut geschmiert werden können und nicht mit Druckfarbe in Berührung gelangen. Außerdem wird der Reibzylinder nur mit Drehmomenten beaufschlagt. Andere antriebsbedingte Kräfte in x- und y-Richtung werden vom Seitengestell aufgenommen. Hierdurch werden einseitige Belastungen der Reibwalze und damit unterschiedliche Anstelldrücke über die Länge der Walze vermieden.The advantage of the invention is that the means provided for both the rotating and the oscillating drive (eg gear wheels) can be arranged outside the side frames, as a result of which they can be well lubricated and do not come into contact with printing ink. In addition, the distribution cylinder is only subjected to torques. Other drive-related forces in the x and y directions are absorbed by the side frame. In this way, one-sided loads on the friction roller and thus different contact pressures over the length of the roller are avoided.

Die Erfindung wird am Beispiel einer Reibwalze 1 beschrieben, die in Oberflächenkontakt mit zwei Farbauftragwalzen 2, 3 steht. Die Farbauftragwalzen 2, 3 wirken mit einem Plattenzylinder 4 zusammen und sind in einem gemeinsamen Schwenkrahmen 6 jeweils auf beiden Seiten einer nicht dargestellten Rotationsdruckmaschine drehbar gelagert. Die Schwenkrahmen 6 sind schwenkbar an den Innenseiten der Seitengestelle 7 der Rotationsdruckmaschine gelagert, von der der einfachheithalber nur eine Seite dargestellt und beschrieben wird. In dem Seitengestell 7 ist in einer Gestellbohrung 8 ein Antriebszahnkranz 9 mittels einer Buchse 11 dreh- und verschiebbar gelagert. Das Zahnrad 8 ist außerhalb des Seitengestells 7 angeordnet und mittels einer weiteren drehbaren Lagerung 12 mit einem Antrieb 10 (z. B. Kurbel- oder Kurvengetriebe oder einem pneumatischen oder hydraulischen Changierantrieb) für eine Hin- und Herbewegung des Zahnrades 8 verbunden. Das Zahnrad 8 steht im Zahneingriff mit einem vom Maschinenantrieb angetriebenen Zahnrad 13, welches außerhalb des Seitengestells 7 in diesem drehbar gelagert ist. Die Zähne 14 des Zahnrades 13 sind so breit ausgeführt, daß sie auch bei einer Hin- und Herbewegung des Zahnrades 8 immer sicher mit den Zähnen 15 des Zahnrades 8 in Antriebskontakt bleiben.The invention is described using the example of a rubbing roller 1 which is in surface contact with two inking rollers 2, 3. The inking rollers 2, 3 cooperate with a plate cylinder 4 and are rotatably mounted in a common swivel frame 6 on both sides of a rotary printing press, not shown. The pivot frames 6 are pivotally mounted on the inner sides of the side frames 7 of the rotary printing press, of which only one side is shown and described for the sake of simplicity. In the side frame 7, a drive sprocket 9 is rotatably and displaceably mounted in a frame bore 8 by means of a bushing 11. The gear wheel 8 is arranged outside the side frame 7 and connected by means of a further rotatable bearing 12 to a drive 10 (for example a crank or cam gear or a pneumatic or hydraulic traversing drive) for a back and forth movement of the gear wheel 8. The toothed wheel 8 is in meshing engagement with a toothed wheel 13 driven by the machine drive, which is rotatably mounted outside of the side frame 7. The teeth 14 of the gear 13 are so wide that they always remain securely in contact with the teeth 15 of the gear 8 even when the gear 8 is moved back and forth.

Die Buchse 11 umgibt koaxial einen Antriebszapfen 16, der fest mit dem Antriebskranz 9 und der Buchse 11 verbunden ist. Der Antriebszapfen 16 ist mittels einer Gelenkkupplung 17 (z. B. einem doppelten Kardangelenk) mit einem Wellenzapfen 18 der Reibwalze 1 formschlüssig verbunden. Selbstverständlich ist es auch möglich den Antriebszahnkranz 9 drehbar und verschiebefest anzuordnen. In diesem Fall ist der Antriebszapfen 16 gegenüber der Buchse 11 und dem Antriebszahnkranz 9 verschiebbar, jedoch drehfest angeordnet (z. B. mittels einer Keilwellen-, Zahnwellen- oder Polygonverbindung).The socket 11 coaxially surrounds a drive pin 16 which is firmly connected to the drive ring 9 and the socket 11. The drive pin 16 is positively connected to a shaft pin 18 of the friction roller 1 by means of an articulated coupling 17 (for example a double universal joint). Of course, it is also possible to arrange the drive sprocket 9 so that it can rotate and move. In this case, the drive pin 16 is displaceable relative to the bush 11 and the drive sprocket 9, but is arranged in a rotationally fixed manner (for example by means of a spline, spline or polygon connection).

Die Reibwalze 1 ist mittels des Wellenzapfens 18 im Schwenkrahmen 6 dreh- und axial verschiebbar gelagert, so daß diese zusammen mit den Farbauftragwalzen 2, 3 von dem ortsfest drehbar in den Seitengestellen 7 gelagerten Plattenzylinder 4 abstellbar ist.The friction roller 1 is rotatably and axially displaceably mounted in the swivel frame 6 by means of the shaft journal 18 so that it can be switched off together with the inking rollers 2, 3 by the plate cylinder 4 which is rotatably mounted in the side frames 7.

Bei einem ersten Ausführungsbeispiel nach Figur 2 weist der gemeinsame Schwenkrahmen 6 eine drehbar gelagerte Steuerrolle 22 auf, die mit einer Steuerkurve 23 in Kontakt stehend angeordnet ist. Der Schwenkrahmen 6 weist eine Druckfeder 24 auf, die an einem der Lagerung des Schwenkrahmens 6 gegenüberliegendem Ende angeordnet ist und stützt sich mittels der Druckfeder 24 am Seitengestell 7 ab.In a first exemplary embodiment according to FIG. 2, the common swivel frame 6 has a rotatably mounted control roller 22 which is arranged in contact with a control cam 23. The swivel frame 6 has a compression spring 24 which is arranged at an end opposite the mounting of the swivel frame 6 and is supported on the side frame 7 by means of the compression spring 24.

Die Farbauftragwalze 2 ist in einem Schlitz des Schwenkrahmens 6 verschiebbar gelagert und mittels einer Einstellschraube 26 verstellbar, so daß ein Achsabstand zwischen der Reibwalze 1 und der Farbauftragwalze 2 einstellbar ist.The inking roller 2 is slidably mounted in a slot of the swivel frame 6 and adjustable by means of an adjusting screw 26, so that an axial distance between the friction roller 1 and the inking roller 2 can be adjusted.

Die Farbauftragwalze 3 ist mittels einer Druckfeder 27 und mittels zweier Einstellschrauben 28, 29 im Schwenkrahmen 6 gelagert, so daß diese an die Reibwalze 1 und den Plattenzylinder 4 anstellbar ist.The inking roller 3 is mounted in the swivel frame 6 by means of a compression spring 27 and by means of two adjusting screws 28, 29, so that it can be adjusted to the friction roller 1 and the plate cylinder 4.

Beim Abstellen der Farbauftragwalzen 2, 3 vom Plattenzylinder 4 drückt die Steuerkurve 23 die Steuerrolle 22 nach außen, so daß der Schwenkrahmen 6 gegen die Kraft der Druckfeder 24 ausgelenkt wird und die im Schwenkrahmen 6 gelagerten Walzen 2 und 3 vom Plattenzylinder 4 abgestellt werden, wobei diese auch zusammen mit dem Reibzylinder 1 gegenüber den Seitengestellen 7 eine ortsverändernde Relativbewegung durchführen.When parking the inking rollers 2, 3 from the plate cylinder 4, the control cam 23 presses the control roller 22 outwards, so that the swivel frame 6 is deflected against the force of the compression spring 24 and the rollers 2 and 3 mounted in the swivel frame 6 are turned off by the plate cylinder 4, whereby they also perform a position-changing relative movement together with the distribution cylinder 1 relative to the side frames 7.

Bei einem zweiten Ausführungsbeispiel ist der Reibzylinder 1 in einem Ende eines verschiebbar im Seitengestell 7 gelagerten Lagerhebels 31 gelagert. Hierbei ist der Lagerhebel 31 sowohl gegenüber dem Seitengestell 7, als auch senkrecht zur Achse des Plattenzylinders 4 verschiebbar angeordnet, wobei sich der Lagerhebel 31 mittels einer Druckfeder 32 am Seitengestell 7 abstützt.In a second exemplary embodiment, the distribution cylinder 1 is mounted in one end of a bearing lever 31 which is displaceably mounted in the side frame 7. Here, the bearing lever 31 is arranged to be displaceable both with respect to the side frame 7 and also perpendicular to the axis of the plate cylinder 4, the bearing lever 31 being supported on the side frame 7 by means of a compression spring 32.

Die Farbauftragwalzen 2, 3 weisen ebenfalls jeder einen eigenen Lagerhebel 33; 34 auf.
Diese sind schwenkbar an einer Innenseite der Seitengestelle 7 angeordnet.
Die Lagerhebel 33; 34 weisen jeweils eine drehbar gelagerte Steuerrolle 36; 37 auf. Zwei gemeinsam betätigbare Steuerkurven 38, 39 sind mit den Steuerrollen 36, 37 in Kontakt stehend angeordnet. Die Lagerhebel 33, 34 weisen je eine Druckfeder 41, 42 auf, mittels der sie sich am Seitengestell 7 abstützen.The inking rollers 2, 3 also each have their own bearing lever 33; 34 on.
These are pivotally arranged on the inside of the side frames 7.
The bearing lever 33; 34 each have a rotatably mounted control roller 36; 37 on. Two jointly operable control cams 38, 39 are arranged in contact with the control rollers 36, 37. The bearing levers 33, 34 each have a compression spring 41, 42, by means of which they are on Support side frame 7.

Beim Abstellen der Farbauftragwalzen 2, 3 vom Plattenzylinder 4 werden mittels der Steuerkurven 38, 39 Steuerrollen 36, 37 nach außen gedrückt, so daß diese zusammen mit den Lagerhebeln 33, 34 und den darin gelagerten Farbauftragwalzen 2, 3 vom Plattenzylinder 4 gegen die Kraft der Federn 41, 42 abgestellt werden.When parking the inking rollers 2, 3 from the plate cylinder 4 are pressed by means of the control cams 38, 39 control rollers 36, 37 so that they together with the bearing levers 33, 34 and the inking rollers 2, 3 stored therein by the plate cylinder 4 against the force of the Springs 41, 42 can be turned off.

Hierbei wirken die Farbauftragwalzen 2, 3 mittels ihrer Oberflächen auf den Reibzylinder 1 ein und verschieben diesen gegen die Kraft der Druckfeder 32, so daß ein Abstand zwischen der Achse 19 des Reibzylinders 1 und der Rotationsachse 21 des Antriebszahnkranzes 9 erzeugt wird.Here, the inking rollers 2, 3 act on the surface of the distribution cylinder 1 and move it against the force of the compression spring 32, so that a distance between the axis 19 of the distribution cylinder 1 and the axis of rotation 21 of the drive ring gear 9 is generated.

In jedem Fall ist ein Spiel s zwischen der Gelenkkupplung 17 und einem Innendurchmesser der Buchse 11 vorgesehen, das es ermöglicht, daß eine Achse 19 des Reibzylinder 1 eine parallele Lageveränderung mit einem Abstand (z. B. ± 5 mm) gegenüber einer Achse 21 des Antriebzahnkranzes 9 durchführt.In any case, a game s is provided between the articulated coupling 17 and an inner diameter of the bushing 11, which enables an axis 19 of the distribution cylinder 1 to make a parallel change in position at a distance (e.g. ± 5 mm) from an axis 21 of the Drive sprocket 9 performs.

In den Ausführungsbeispielen ist nur der Reibzylinder 1 mit der erfindungsgemäßen Antriebsvorrichtung versehen. Selbstverständlich ist es jedoch auch möglich z. B. die Farbauftragwalzen 2 und 3 mit dieser Antriebsvorrichtung auszurüsten.In the exemplary embodiments, only the distribution cylinder 1 is provided with the drive device according to the invention. Of course, it is also possible, for. B. equip the inking rollers 2 and 3 with this drive device.
