Description

Die Erfindung betrifft einen Zylinderantrieb für eine RotationsdruckmaschineThe invention relates to a cylinder drive for a rotary printing press

Aus der DE 41 38 479 C2 ist ein gattungsgemäßer Zylinderantrieb einer Rotationsdruckmaschine bekannt. Ein mittels einer Exzenterbuchse in einem Seitengestell schwenkbarer Zylinder wird mittels eines Elektromotores direkt angetrieben. Dazu ist ein Rotor des Elektromotores fest mit einem Zapfen des Zylinders verbunden. Ein Stator des Elektromotors ist mittels einer Vorrichtung zum Nachführen mit dem Seitengestell fest verbunden.
Nachteilig ist hierbei, daß eine aufwendige Vorrichtung zum Nachführen des Stators notwendig ist. Zudem sind Stator und Rotor des Elektromotores nicht direkt relativ zueinander drehbar gelagert, so daß ein gleichbleibender Luftspalt zwischen Rotor und Stator nicht gewährleistet ist. Derartige Ungenauigkeiten können insbesondere durch Fertigungsungenauigkeiten, Montagefehler oder die Vorrichtung zum Nachführen selbst auftreten. Hierdurch können unerwünschte Schwingungen entstehen, die beispielsweise zu Dublieren im Druckbild führen können.From DE 41 38 479 C2 a generic cylinder drive of a rotary printing press is known. A cylinder that can be swiveled in a side frame by means of an eccentric bushing is driven directly by an electric motor. For this purpose, a rotor of the electric motor is firmly connected to a pin of the cylinder. A stator of the electric motor is firmly connected to the side frame by means of a tracking device.
The disadvantage here is that a complex device for tracking the stator is necessary. In addition, the stator and rotor of the electric motor are not directly rotatably supported relative to each other, so that a constant air gap between the rotor and stator is not guaranteed. Such inaccuracies can occur in particular due to manufacturing inaccuracies, assembly errors or the device for tracking itself. This can cause undesirable vibrations, which can lead to duplication in the printed image, for example.

Die DE 44 22 097 A1 beschreibt eine Anordnung eines Elektromotors zum Antrieb eines Druckzylinders einer Rotationsdruckmaschine, der in einer verstellbaren Exzenterbuchse drehgelagert ist. Dabei ist ein Rotor des Elektromotors mit dem Zylinder starr verbunden.DE 44 22 097 A1 describes an arrangement of an electric motor for driving a printing cylinder of a rotary printing press, which is rotatably supported in an adjustable eccentric bushing. A rotor of the electric motor is rigidly connected to the cylinder.

Die DE 44 30 693 A1 zeigt eine Offsetrotationsdruckmaschine mit einer Druckeinheit mit einem in einer Exzenterbuchse gelagerten Zylinder. Dieser Zylinder wird mittels eines Elektromotors direkt angetrieben, wobei ein Stator des Elektromotors an einem Zapfen des Zylinders starr befestigt ist.DE 44 30 693 A1 shows an offset rotary printing press with a printing unit with a cylinder mounted in an eccentric bushing. This cylinder is driven directly by means of an electric motor, a stator of the electric motor being rigidly attached to a pin of the cylinder.

Die DE 34 32 572 A1 offenbart einen Zylinderantrieb, bei dem ein Rotor eines Elektromotors mittels einer Schnellkupplung mit einem Zapfen des Zylinders verbunden ist. Diese Schnellkupplung verbindet Zapfen und Rotor starr.
Die CH 452 288 zeigt einen Antrieb eines in einer Exzenterbuchse verschwenkbaren Plattenzylinders, wobei ein Antrieb über ein Antriebsrad eines Getriebes und ein Kupplungsteil erfolgt, welches eine Winkelbeweglichkeit zwischen einem Zapfen des Zylinders und dem Antriebsrad ermöglicht.DE 34 32 572 A1 discloses a cylinder drive in which a rotor of an electric motor is connected to a journal of the cylinder by means of a quick coupling. This quick coupling rigidly connects the journal and rotor.
CH 452 288 shows a drive of a plate cylinder which can be pivoted in an eccentric bushing, a drive being effected via a drive wheel of a transmission and a coupling part which enables angular mobility between a pin of the cylinder and the drive wheel.

Der Erfindung liegt die Aufgabe zugrunde, einen Zylinderantrieb einer Rotationsdruckmaschine zu schaffen.The invention has for its object to provide a cylinder drive of a rotary printing press.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 oder 2 gelöst.This object is achieved by the features of claim 1 or 2.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß bei Verstellung des Zylinders keine Relativbewegung zwischen Stator und Rotor eines den Zylinder antreibenden Elektromotors auftreten kann. Somit ist ein gleichbleibender Luftspalt zwischen Stator und Rotor gewährleistet, wodurch gleichbleibend gute Laufeigenschaften des Elektromotors sichergestellt sind.The advantages which can be achieved with the invention consist in particular in that, when the cylinder is adjusted, no relative movement between the stator and rotor of an electric motor driving the cylinder can occur. This ensures a constant air gap between the stator and rotor, which ensures consistently good running properties of the electric motor.

Bei dem erfindungsgemäßen Zylinderantrieb wird beispielsweise ein Flanschmotor verwendet, dessen Flansch direkt stirnseitig an einer den Zylinder aufnehmenden Exzenterbuchse, befestigt ist. Hierzu sind keine aufwendigen Nachführeinrichtungen notwendig. Herstellungs- und Montagekosten sowie Ungenauigkeiten werden minimiert.
Ist der Zylinder und der Elektromotor mittels einer Kupplung verbunden, kann diese beispielsweise Fehler wie Achsversatz, Schrägstellung der Achsen oder Winkelfehler ausgleichend angebracht sein, wodurch solche Fehler keinen Einfluß auf beispielsweise Lebensdauer oder Laufeigenschaften des Elektromotors haben. Dies ist insbesondere bei einem mittels einer Exzenterbuchse verstellbaren Zylinder vorteilhaft, da dieser je nach Stellung der Exzenterbuchse unterschiedlich belastet sein kann und deshalb beispielsweise ein Achsversatz zwischen Rotor des Elektromotors und Zapfen des Zylinder verschieden groß sein kann.In the cylinder drive according to the invention, for example, a flange motor is used, the flange of which is fastened directly on the end face to an eccentric bushing receiving the cylinder. No complex tracking devices are required for this. Manufacturing and assembly costs as well as inaccuracies are minimized.
If the cylinder and the electric motor are connected by means of a clutch, this can, for example, compensate for errors such as axis misalignment, inclined axes or angular errors, so that such errors have no influence on, for example, the service life or running properties of the electric motor. This is particularly advantageous in the case of a cylinder adjustable by means of an eccentric bushing, since this can be loaded differently depending on the position of the eccentric bushing and therefore, for example, an axial offset between the rotor of the electric motor and the journal of the cylinder can be of different sizes.

Der erfindungsgemäße Zylinderantrieb ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.The cylinder drive according to the invention is shown in the drawing and is described in more detail below.

Ein Zapfen 1 eines als Form-,Gummi- oder Druckzylinder ausgeführten Zylinders 2 einer Rotationsdruckmaschine ist in einem Seitengestell 3 beispielsweise mittels eines Wälzlagers 4 um seine Drehachse 6 drehbar gelagert. Dieses Wälzlager 4 ist in einer Exzenterbuchse 7 angeordnet, die wiederum mittels eines Wälzlagers 8 in dem Seitengestell 3 schwenkbar gelagert ist. An dieser Exzenterbuchse 7 greift ein erstes Ende eines Stellantrieb, beispielsweise eines steuerbaren Arbeitszylinders 9 mittels eines ersten Gelenkes an. Ein zweites Ende des Arbeitszylinders 9 ist mittels eines zweiten Gelenkes mit dem Seitengestell 3 verbunden. Mit dem Arbeitszylinder 9 können Feineinstellvorrichtungen zusammenwirkend angeordnet sein. Somit ist die Exzenterbuchse 7 mit dem Seitengestell 3 verdrehgesichert und einstellbar verbunden und eine Lage der Drehachse 6 des Zylinders 2 ist in einer von dem Seitengestell 3 aufgespannten Ebene mittels der Exzenterbuchse 7 veränderbar. Mit dem Zylinder 2 ist ein lagegeregelter Elektromotor 11 zusammenwirkend angeordnet. Dazu ist der Zapfen 1 des Zylinders 2 mittels einer Kupplung 12 mit einer Rotorwelle 13 eines Rotors 14 des Elektromotors 11 drehsteif verbunden. Die Kupplung 11 kann wie im dargestellten Beispiel als einfache Flanschkupplung oder beispielsweise auch als gelenkige Ausgleichskupplung wie z. B.
Doppelkardangelenk, Bogenzahnkupplung ausgeführt sein. Der Rotor 14 bzw. die Rotorwelle 13 ist in einem Flansch 16 und einem Deckel 17 eines einen Stator 18 enthaltenden Gehäuses 19 beispielsweise mittels Gleitlager gelagert. Der Flansch 16 ist stirnseitig mit der Exzenterbuchse 7 verbunden.
Der Elektromotor 11, d.h. sein Stator 18, ist somit vorzugsweise ausschließlich an der Exzenterbuchse 7 befestigt.A pin 1 of a cylinder 2 of a rotary printing press designed as a forme, rubber or impression cylinder is mounted in a side frame 3, for example by means of a roller bearing 4, so that it can rotate about its axis of rotation 6. This roller bearing 4 is arranged in an eccentric bushing 7, which in turn is pivotally mounted in the side frame 3 by means of a roller bearing 8. A first end of an actuator, for example a controllable working cylinder 9, engages on this eccentric bushing 7 by means of a first joint. A second end of the working cylinder 9 is connected to the side frame 3 by means of a second joint. Fine adjustment devices can be arranged to cooperate with the working cylinder 9. Thus, the eccentric bush 7 is secured against rotation and adjustably connected and a position of the axis of rotation 6 of the cylinder 2 can be changed in a plane spanned by the side frame 3 by means of the eccentric bush 7. A position-controlled electric motor 11 is arranged to cooperate with the cylinder 2. For this purpose, the pin 1 of the cylinder 2 is connected to a rotor shaft 13 of a rotor 14 of the electric motor 11 in a torsionally rigid manner by means of a coupling 12. The coupling 11 can, as in the example shown, as a simple flange coupling or, for example, also as an articulated compensating coupling such as. B.
Double cardan joint, curved tooth coupling. The rotor 14 or the rotor shaft 13 is mounted in a flange 16 and a cover 17 of a housing 19 containing a stator 18, for example by means of slide bearings. The flange 16 is connected on the end face to the eccentric bushing 7.
The electric motor 11, ie its stator 18, is therefore preferably exclusively attached to the eccentric bushing 7.

Anstelle der Gleitlager sind auch Wälzlager anwendbar.Instead of plain bearings, rolling bearings can also be used.

Auch ist ein Hohlwellenmotor anwendbar, der auf direkt auf den Zapfen 1 aufschiebbar ist. Der Zapfen 1 ist dabei zum Rotor des Hohlwellenmotors mittels Paßfeder, Vielkeilwelle oder Kerbverzahnung verdrehgesichert. Zwischen Elektromotor 11 und Zapfen 1 kann auch ein Getriebe zwischengeschaltet sein, das auch ausschließlich auf der Exzenterbuchse 7 angeordnet ist. Dieses Getriebe ist als Planetenradgetriebe ausgebildet und koaxial zum Zapfen 1 angeordnet.A hollow shaft motor can also be used, which can be pushed directly onto the journal 1. The pin 1 is secured against rotation to the rotor of the hollow shaft motor by means of a feather key, splined shaft or serration. A transmission can also be interposed between the electric motor 11 and the pin 1, which is also arranged exclusively on the eccentric bushing 7. This gear is designed as a planetary gear and arranged coaxially to the pin 1.

Die Funktionsweise des erfindungsgemäßen Zylinders 1 ist folgendermaßen: Wird der Arbeitszylinder 9 beispielsweise zur Druckanstellung betätigt, übt dieser eine Kraft in Umfangsrichtung auf die Exzenterbuchse 7 aus. Dadurch wird die Exzenterbuchse 7 in Umfangsrichtung geschwenkt bis beispielsweise ein nichtdargestellter Anschlag erreicht wird. Dadurch wird die Lage der Drehachse 6 des Zylinders 2 zum Seitengestell 3 und damit beispielsweise zu einem zweiten Zylinder verändert. Dabei wird auch gleichzeitig eine Lage sowohl des Rotors 14 wie auch des Stators 18 verändert. Es entsteht aber keine Relativbewegung zwischen Rotor 14 und Stator 18, so daß ein Luftspalt zwischen Rotor 14 und Stator 18 konstant bleibt.The operation of the cylinder 1 according to the invention is as follows: If the working cylinder 9 is actuated for pressure adjustment, for example, it exerts a force in the circumferential direction on the eccentric bushing 7. As a result, the eccentric bushing 7 is pivoted in the circumferential direction until, for example, a stop (not shown) is reached. This changes the position of the axis of rotation 6 of the cylinder 2 relative to the side frame 3 and thus, for example, to a second cylinder. A position of both the rotor 14 and the stator 18 is also changed at the same time. However, there is no relative movement between rotor 14 and stator 18, so that an air gap between rotor 14 and stator 18 remains constant.
