Description

Die Erfindung befasst sich mit einer Lösung zur Befestigung eines Antriebes, wie er in Druckmaschinen mit Seitenregisterverstellung verwendet wird.The invention relates to a solution for fixing a drive, as used in printing machines with side register adjustment.

Aus dem Stand der Technik sind derartige Anordnungen bekannt. Beispielsweise zeigt die DE 41 43 597 C2 eine Druckmaschine mit einem elektromotorisch angetriebenen Zylinder, welcher axial längs verstellbar ist. Der Zylinder wird von einem Direktantrieb angetrieben. Die Seitenregisterverstellung wird unter anderem dadurch gewährleistet, dass der Luftspalt zwischen Stator und Rotor ausgenutzt wird. Bei dieser Lösung müssen der Rotor oder der Stator länger ausgeführt sein, um ohne Drehmomentverlust eine axiale Beweglichkeit zu gewährleisten. Dies bedeutet einen erhöhten Materialaufwand und damit erhöhte Kosten.Such arrangements are known from the prior art. For example, the shows DE 41 43 597 C2 a printing machine with an electric motor-driven cylinder, which is axially adjustable longitudinally. The cylinder is driven by a direct drive. The side register adjustment is ensured, inter alia, that the air gap between the stator and rotor is utilized. In this solution, the rotor or the stator must be made longer in order to ensure axial mobility without loss of torque. This means an increased cost of materials and thus increased costs.

Die Aufgabe der Erfindung liegt darin, einen kostengünstigen und im Servicefalle leicht auswechselbaren Druckmaschinenantrieb für Druckmaschinen mit Seitenregisterverstellung zu realisieren.The object of the invention is to realize a cost-effective and easily replaceable in case of service printing press drive for printing presses with side register adjustment.

Die Erfindung löst diese Aufgabe mittels eines Direktantriebes für eine Druckmaschine mit Seitenregisterverstellung, wobei der Antrieb einen Rotor und einen Stator sowie Verbindungsmittel zur mechanischen Verbindung des Antriebs mit einem ortsfesten Widerlager umfasst und der Rotor mit der Welle eines Druckmaschinenzylinders verbindbar ist, wobei das Verbindungsmittel ein mittelbar oder unmittelbar am Außenmantel des Antriebes angebrachtes, torsionssteifes Abstandsmittel ist, welches in Richtung der Motorachse zur Kompensation von axialen Bewegungen der anschließbaren Druckmaschinenzylinderwelle elastisch ausgebildet ist.The invention solves this problem by means of a direct drive for a printing machine with side register adjustment, wherein the drive comprises a rotor and a stator and connecting means for mechanically connecting the drive with a stationary abutment and the rotor with the shaft of a printing press cylinder is connectable, wherein the connecting means indirectly or directly mounted on the outer jacket of the drive, torsionally rigid spacer means which is designed to be elastic in the direction of the motor axis for compensation of axial movements of the connectable printing cylinder cylinder shaft.

Der Vorteil der Erfindung liegt darin, dass der Antrieb als komplette Einheit die axiale Bewegung des Druckmaschinenzylinders mitmacht und völlig unabhängig' von der Konfiguration der Druckmaschine hergestellt werden kann. Außerdem kann der Antrieb klein und kompakt gebaut werden, weil die gesamte Statorlänge bzw. Rotorlänge zur Drehmomenterzeugung genutzt wird. Im Servicefalle ist der Antrieb als Ganzes leicht aüswechselbar, ganz im Gegensatz zu dem im Stand der Technik gezeigten Antrieb, welcher zunächst von seiner aufwendigen Lagerung befreit werden müsste, um die Einzelteile des Antriebes auszuwechseln.The advantage of the invention is that the drive participates as a complete unit the axial movement of the printing press cylinder and can be made completely independent 'of the configuration of the printing press. In addition, the drive can be made small and compact, because the entire stator length or rotor length is used for torque generation. In case of service the drive as a whole is light azuswechselbar, in contrast to the drive shown in the prior art, which would first have to be freed from its complex storage to replace the individual parts of the drive.

Bevorzugt ist der Querschnitt des Verbindungsmittels entsprechend des Außenquerschnittes des Antriebes ausgebildet und liegt am Außenmantel oder einem am Stator angebrachten Zwischenlager an. Ein Zwischenlager kann unter Umständen erforderlich sein, wenn die axiale Kraft des Motors nicht zur Verschiebung gegen die Kraft des Verbindungselements ausreicht.Preferably, the cross section of the connecting means is formed according to the outer cross section of the drive and is located on the outer jacket or attached to the stator intermediate storage. An intermediate bearing may be required in circumstances where the axial force of the motor is insufficient to displace the force of the connecting element.

Besonders bevorzugt ist das Verbindungsmittel mittels eines Federelementes, vorzugsweise einer am Antriebsumfang angeordneten Tellerfeder, realisiert. Die Tellerfeder hat den Vorteil, dass diese torsionssteif und axial weich ausgebildet ist, was die Abfederung der axialen Bewegung bewirkt.Particularly preferably, the connecting means is realized by means of a spring element, preferably a plate spring arranged on the drive circumference. The plate spring has the advantage that it is torsionally rigid and axially soft, which causes the cushioning of the axial movement.

Alternativ kann das Verbindungsmittel mittels eines Kragarmes realisiert werden, welcher an mindestens einer Stirnseite den Stator an einem Widerlager abstützt: Der Kragarm ersetzt dann die oben erwähnte Tellerfeder. Der Vorteil dieser Variante besteht darin; daß besonders geringe Gegenkräfte bei der axialen Verstellung zu überwinden sind. Somit wäre eine solche Ausführung insbesondere für Asynchronmaschinen und Reluktanzmaschinen geeignet, um so die geringeren Rückstellkräfte auszunutzen.Alternatively, the connecting means can be realized by means of a cantilever, which supports the stator on an abutment on at least one end face: The cantilever then replaces the above-mentioned disc spring. The advantage of this variant is; that particularly low opposing forces are to overcome in the axial adjustment. Thus, such an embodiment would be particularly suitable for asynchronous machines and reluctance machines, so as to take advantage of the lower restoring forces.

Besonders bevorzugt wird der Außenquerschnitt des Antriebes, im wesentlichen rechteckig ausgeführt, da hierdurch eine große Kontaktfläche zum meist ebenfalls rechteckigen Querschnitt des Widerlagers realisierbar ist. Zusätzlich wird hierdurch ein langer Federweg realisiert, was zu einem geringeren Kraftaufwand führt, um den Druckmaschinenzylinder zu bewegen.Particularly preferably, the outer cross-section of the drive is made substantially rectangular, since in this way a large contact area can be realized to the usually also rectangular cross-section of the abutment. In addition, this provides a long spring travel, resulting in less effort to move the printing press cylinder.

Vorzugsweise umfasst der Antrieb eine Feedbackeinrichtung, welche mit dem Rotor verbunden und am Stator abgestützt ist. Bei einer axialen Verschiebung der Welle des Druckmaschinenzylinders verschieben sich der Rotor, der Stator und der Geber gleichzeitig und relativ zum Gehäuse mit der Welle. Die Geberankopplung gestaltet sich daher sehr einfach und es ist keine separate, axial verschiebbare:Lagerung des Gebers erforderlich.Preferably, the drive comprises a feedback device, which is connected to the rotor and supported on the stator. With an axial displacement of the shaft of the printing press cylinder, the rotor, the stator and the encoder move simultaneously and relative to the housing with the shaft. The encoder coupling is therefore very simple and there is no separate, axially displaceable: storage of the encoder required.

Wird eine Druckmaschine mit Seitenregisterverstellung mit einem Direktantrieb nach einem der vorherigen Ansprüche ausgestattet, so erhält man eine bezüglich des Direktantriebes wartungsfreundliche und einfach zu montierende Maschine. Der Motor kann als Komplettmotor montiert und demontiert werden. Aufwändige Motorbausätze und Lagerungen entfallen. Die Druckmaschine kann außerdem kompakter realisiert werden, da weniger Bauraum für den Antrieb bereitgehalten werden muss.If a press is equipped with side register adjustment with a direct drive according to one of the preceding claims, we obtain a respect to the direct drive maintenance-friendly and easy to install machine. The motor can be assembled and disassembled as a complete motor. Elaborate engine kits and bearings eliminated. The printing press can also be realized more compact, since less space must be kept ready for the drive.

Figur 1 und 2 zeigen zwei Varianten des erfindungsgemäßen Direktantriebes 10, dessen Rotor 7 an der Welle 2 einer Walze 1 mittels eines Klemmelementes 12 aufgeklemmt ist. Die Welle 2 ist mittels der Wellenlagerung 3 gelagert. Diese Wellenlagerung 3 liegt an einer Wandung 4 an, durch die die Druckmaschinenwelle 2 geführt ist. Gegenüber der Lagerung 3 ist der Antrieb 10 angeordnet, welcher von einem Gehäuse 5 abgedeckt ist. Außerdem ist der Stator 8, Tellerfedern 9, die Statorarretierung 11, ein Stator-Rotor Lager 13 (nur Figur 1) sowie ein Geber 6 gezeigt.Figures 1 and 2 show two variants of the direct drive 10 according to the invention, the rotor 7 is clamped on the shaft 2 of a roller 1 by means of a clamping element 12. The shaft 2 is supported by means of the shaft bearing 3. This shaft bearing 3 abuts against a wall 4, through which the printing machine shaft 2 is guided. Opposite the bearing 3, the drive 10 is arranged, which is covered by a housing 5. In addition, the stator 8, disc springs 9, the Statorarretierung 11, a stator-rotor bearing 13 (only Figure 1) and an encoder 6 is shown.

Bei der in Figur 1 gezeigten Variante der Erfindung handelt es sich um einen Antrieb 10, welcher keine permanente Kraftwirkung aufweist und dessen Luftspalt mittels der zusätzlichen Lagerung 13 zur Arretierung des Stators 8 realisiert wird. Der Rotor 7 des Antriebs 10 ist aufgrund seiner Anordnung am Umfang der Welle 2 koaxial zum Stator 8 angeordnet. Der zwischen Stator 8 und Rotor 7 vorhandene Luftspalt bleibt aufgrund dieser Lagerung konstant, auch wenn kein Magnetfeld wirkt.The variant of the invention shown in FIG. 1 is a drive 10 which has no permanent force effect and whose air gap is realized by means of the additional bearing 13 for locking the stator 8. The rotor 7 of the drive 10 is arranged coaxially to the stator 8 due to its arrangement on the circumference of the shaft 2. The existing between stator 8 and rotor 7 air gap remains constant due to this storage, even if no magnetic field acts.

Bei der zweiten Variante (siehe Figur 2) ist kein Stator-Rotor Lager 13 erforderlich, weil ein Magnetfeld permanent vorhanden ist und somit automatisch den für den Betrieb der Anordnung erforderlichen Lusftspalt zwischen Rotor 7 und Stator 8 aufrecht erhält.In the second variant (see Figure 2) no stator rotor bearing 13 is required because a magnetic field is permanently present and thus automatically maintains the required for the operation of the arrangement Lusftspalt between the rotor 7 and stator 8 upright.

In beiden Fällen wird der Antrieb mittels der Tellerfeder(n) 9, welche zwischen dem äußerem Umfang der Rotorarretierung 11 und dem Gehäuse 5 des Antriebs 10 angeordnet ist (sind), koaxial zur Drehachse gehalten. Die Tellerfeder(n) 9 ist (sind) torsionssteif und hält (halten) den Antrieb 10 auch bei Drehung der Welle 2 in radialer Richtung innerhalb des Gehäuses auf im wesentlichen konstanter Position. Bewegt sich die Welle 2 jedoch axial bei Durchführung einer Seitenregisterverstellung, so gibt die in axialer Richtung weiche Feder 9 nach und ermöglicht eine radial gelagerte Bewegung der Anordnung (Zylinder 1 + Antrieb 10) in axialer Richtung. Der Geber 6 ist mit dem Rotor 7 fest verbunden und wird am Stator 8 abgestützt. Bewegt sich die Welle 2 in axialer Richtung, so bewegt sich der Antrieb 10 zusammen mit der Welle 2 und dem Geber 6 innerhalb des Gehäuses ebenfalls in axialer Richtung. Im Wartungsfalle ist der Antrieb 10 durch Entfernen des Gehäuses 5 leicht zugänglich, kann von der Welle 2 abgezogen und somit ohne großen Aufwand ausgewechselt werden.In both cases, the drive by means of the plate spring (s) 9, which is (are) arranged between the outer periphery of the rotor lock 11 and the housing 5 of the drive 10, coaxial with the axis of rotation. The plate spring (s) 9 is (are) torsionally rigid and keeps (hold) the drive 10 even when the shaft 2 rotates in the radial direction within the housing at a substantially constant position. However, the shaft 2 moves axially when performing a Seitenregisterverstellung, so gives the soft spring 9 in the axial direction and allows a radially mounted movement of the assembly (cylinder 1 + drive 10) in the axial direction. The encoder 6 is fixedly connected to the rotor 7 and is supported on the stator 8. If the shaft 2 moves in the axial direction, then the drive 10 together with the shaft 2 and the encoder 6 within the housing also moves in the axial direction. In the case of maintenance, the drive 10 is easily accessible by removing the housing 5, can be deducted from the shaft 2 and thus replaced without much effort.

Anstelle der Tellerfeder 9 könnte beispielsweise an der dem Stator 8 zugewandten Innenseite der Gehäuseabdeckung 5 und an der Stirnseite des Stators 8 eine Kragarmkonstruktion angeordnet sein, welche eine axiale Verschiebung der Anordnung zulässt. Auch Kragarme an weiteren geeigneten Stellen wären denkbar.Instead of the plate spring 9, a cantilever construction could, for example, be arranged on the inner side of the housing cover 5 facing the stator 8 and on the end face of the stator 8, which permits an axial displacement of the arrangement. Even cantilevers in other suitable places would be conceivable.
