Beschrei bungDescription
ZylinderantriebCylinder drive
Die Erfindung betrifft einen Zylinderantrieb für eine Rotationsdruckmaschine gemäß dem Oberbegriff des Anspruc hes 1.The invention relates to a cylinder drive for a rotary printing press according to the preamble of claim 1.
Aus der DE 41 38 479 C2 ist ein gattungsgemäßer Zyl nderantrieb einer Rotationsdruckmaschine bekannt. Ein mittels einer Exzenterbuchse in einem Seitengestell schwenkbarer Zylinder wird mittels eines E lekt romotores direkt angetrieben. Dazu ist ein Rotor des E lekt ro otore s fest mit einem Zapfen des Zylinders verbunden. Ein Stator des Elektromotors ist mittels einer Vorrichtung zum Nachführen mit dem Seitengestell fest verbunden.From DE 41 38 479 C2 a generic cylinder drive of a rotary printing press is known. A cylinder that can be swiveled by means of an eccentric bushing in a side frame 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.
Nachteilig ist hierbei, daß eine aufwendige Vorrichtung zum Nachführen des Stators notwendig ist. Zudem sind Stator und Rotor des E lekt romotores nicht direkt relativ zueinander drehbar gelagert, so daß ein gleichbleibender Luftspalt zwischen Rotor und Stator nicht gewährleistet ist. Derartige Ungenauigkei ten können insbesondere durch Fe rt i gungsungenaui gke i en, Montagefehler oder die Vorrichtung zum Nachführen selbst auftreten. Hierdurch können unerwünschte Schwingungen entstehen, die beispielsweise zu Dublieren im Druckbild führen können.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 one another, 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 Druckzyl nders 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 a Electric motor for driving a Druckzyl nders a rotary printing press, which is rotatably mounted in an adjustable eccentric bush. A rotor of the electric motor is rigidly connected to the cylinder.

Of f set rotat i onsdruc k as chi ne 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.Of f set rotat i onsdruc k as chi ne with a printing unit with a cylinder mounted in an eccentric bush. 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 Zyl nderantrieb, bei dem ein Rotor eines Elektromotors mittels einerDE 34 32 572 A1 discloses a cylinder drive, in which a rotor of an electric motor by means of a
Sc hne l l kupplung mit einem Zapfen des Zylinders verbunden ist. Diese Sehne l l kupplung verbindet Zapfen und Rotor starr.Quick coupling is connected to a pin of the cylinder. This tendon oil coupling rigidly connects the journal and the rotor.
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 kennzeichnenden Teiles des Anspruches 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß bei Verstellung des Zylinders keine Relat bewegung zwischen Stator und Rotor eines den Zylinder antreibenden Elektromotors auftreten kann. Somit ist ein gleichbleibender Luftspalt zwischen Stator und Rotor gewährleistet, wodurch gle chble bend gute Lauf ei genschaften des Elektromotors sichergestellt sind.The advantages that can be achieved with the invention are, in particular, that when the cylinder is adjusted, no relat 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 the 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. Her s te l lungs- und Montage kos ten sowie Ungenaui gke t en werden minimiert.A flange motor, for example, is used in the cylinder drive according to the invention Flange is directly attached to an eccentric bushing receiving the cylinder. No complex tracking devices are necessary for this. Manufacturing and assembly costs as well as inaccuracies are minimized.
Ist der Zylinder und der Elektromotor mittels einer Kupplung verbunden, kann diese be spielswe se Fehler wie Achsversatz, Schrägstellung der Achsen oder Winkelfehler ausgleichend angebracht sein, wodurch solche Fehler keinen Einfluß auf beispielsweise Lebensdauer oder Lauf e i gens chaf ten 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.If the cylinder and the electric motor are connected by means of a clutch, these errors, for example errors such as axis misalignment, inclined axes or angular errors, can be compensated, 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 axis 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 rotierendes Bauteil, vorzugsweise ein Zapfen 1 eines Zylinders 2 (z. B. Form-, Gummi- oder Druckz linder) einer Rotationsdruckmaschine ist in einem Seitengestell 3 beispielsweise mittels eines Wälzlagers 4 um seine Drehachse 6 drehbar gelagert. Dieses Wälzlager 4 ist i 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, beispielswe se eines steuerbaren Arbeitszylinders 9 mittels eines ersten Gelenkes an. Ein zweites Ende des Arbeitszylinders 9 ist mittels eines zweiten Gelenkes mit dem Se i tenges t e L l 3 verbunden. Mit dem Arbei sz linder 9 können Fe i nei nste l l vor r i cht ungen 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 aufgespannt n Ebene mittels der Exzenterbuchse 7 veränderbar. Mit dem Zylinder 2 ist vorzugsweise ein lagegeregelter Elektromotor 11 zusammenwirkend angeordnet. Dazu ist beispielsweise 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 Ausg le i chs upp lung wie z. B.A rotating component, preferably a pin 1 of a cylinder 2 (z. B. Form-, rubber or Druckz linder) of a rotary printing press is rotatably mounted in a side frame 3, for example by means of a roller bearing 4 about its axis of rotation 6. This roller bearing 4 is arranged in an eccentric bushing 7, which in turn can be pivoted in the side frame 3 by means of a roller bearing 8 is stored. At this eccentric bush 7 engages a first end of an actuator, for example se a controllable working cylinder 9 by means of a first joint. A second end of the working cylinder 9 is connected by means of a second joint to the side leg L l 3. With the working lens 9, finest features can be arranged interactively. 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 an n plane spanned by the side frame 3 by means of the eccentric bush 7. A position-controlled electric motor 11 is preferably arranged to cooperate with the cylinder 2. For this purpose, for example, the pin 1 of the cylinder 2 is connected by means of a coupling 12 to a rotor shaft 13 of a rotor 14 of the electric motor 11 in a torsionally rigid manner. The coupling 11 can, as in the example shown, as a simple flange coupling or, for example, also as an articulated compensation such as. B.
Doppe l kardange lenk, 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.Double l cardan steering, curved tooth coupling to be executed. 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.
Der Elektromotor 11, d.h. sein Stator 18, ist somit vorzugsweise ausschließlich an der Exzenterbuchse 7 bef est i gt . Anstelle der Gleitlager sind auch Wälzlager anwendbar. Für den Fall, daß der Stator 18 fest mit dem Zapfen 1 verbunden ist, kann die interne Lagerung des Elektromotors 11 auch ganz entfallen.The electric motor 11, ie its stator 18, is therefore preferably attached exclusively to the eccentric bushing 7. Instead of plain bearings, rolling bearings can also be used. In the event that the stator 18 is firmly connected to the pin 1, the internal mounting of the electric motor 11 can also be omitted entirely.
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, i e l ke Iwe l le oder Kerbverzahnung verdrehgesichert. Zwischen Elektromotor 11 und Zapfen 1 kann auch ein Getriebe zwischengeschaltet sein, das auch ausschließlich auf der Exzenterbuc se 7 angeordnet ist. Dieses Getriebe ist vorzugsweise alsA 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 key, i e l ke Iwe l le or serration. Between the electric motor 11 and pin 1, a transmission can also be interposed, which is also arranged exclusively on the Exzenterbuc se 7. This gear is preferably as
P l ane t enradget ri ebe ausgebildet und koaxial zum Zapfen 1 angeordnet .P l ane t enradget ri ebe formed and arranged coaxially to the pin 1.
Die Funktionsweise des erf ndungsgemäßen Zylinders 1 ist folgendermaßen: Wird der Arbeitsz linder 9 beispielsweise zur Druckanstellung betätigt, übt dieser eine Kraft in Umf ang s ri ch tung auf die Exzenterbuchse 7 aus. Dadurch wird die Exzenterbuchse 7 in Umf angs r i chtung geschwenkt bis beispielsweise ein ni c htda rgeste l Ite r 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 Re L a t i bewegung 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 example, for pressure adjustment, 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 low-pressure stop is reached. As a result, 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 is changed. A position of both the rotor 14 and the stator 18 is also changed at the same time. But there is no re lati movement between rotor 14 and stator 18 so that an air gap between rotor 14 and stator 18 remains constant.
