Description
Die Erfindung betrifft eine Flexodruckmaschine mit einem zentralen Gegendruckzylinder sowie diesen umgebenden Format- und Farbzylindern. Des Weiteren betrifft die Erfindung ein Verfahren zum Betrieb einer Flexodruckmaschine.The invention relates to a flexographic printing press with a central impression cylinder and surrounding format and color cylinders. Furthermore, the invention relates to a method for operating a flexographic printing machine.
Eine Flexodruckmaschine ist beispielsweise aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Flexodruckmaschine anzugeben, welche bei einfachem Aufbau eine schnelle, exakte und voneinander unabhängige Verstellung eines Formatzylinders und eines Farbzylinders ermöglicht. Des Weiteren besteht die Aufgabe, das Betriebsverhalten einer Flexodruckmaschine zu verbessern.The invention has for its object to provide a flexographic printing machine, which allows for a simple structure, a fast, accurate and mutually independent adjustment of a format cylinder and a color cylinder. Furthermore, the object is to improve the performance of a flexographic printing machine.
Diese Aufgaben werden durch eine Flexodruckmaschine mit den Merkmalen des Anspruchs 1 sowie durch ein Verfahren zum Betrieb einer Flexodruckmaschine mit den Merkmalen des Anspruchs 8 gelöst. Im Folgenden im Zusammenhang mit der Vorrichtung genannte Ausgestaltungen und Vorteile gelten sinngemäß auch für das Verfahren und umgekehrt.These objects are achieved by a flexographic printing machine with the features of claim 1 and by a method for operating a flexographic printing machine having the features of
Die Flexodruckmaschine weist in an sich bekannter Art einen zentralen Gegendruckzylinder und mehrere Paare aus jeweils einem Formatzylinder und einem Farbzylinder auf. Beim Betrieb der Flexodruckmaschine liegen die Formatzylinder am Gegendruckzylinder an und werden ihrerseits von jeweils einem Farbzylinder kontaktiert. Zur Veränderung der Abstände der Drehachsen der Formatzylinder und Farbzylinder von der Drehachse des Gegendruckzylinders sind Verfahreinrichtungen vorgesehen. Jede Verfahreinrichtung ermöglicht eine unabhängige Verstellung eines Formatzylinders und eines Farbzylinders.The flexographic printing machine has, in a manner known per se, a central counter-pressure cylinder and a plurality of pairs each consisting of a format cylinder and a color cylinder. During operation of the flexographic printing machine, the format cylinders abut on the impression cylinder and in turn are contacted by a respective color cylinder. Moving devices are provided for changing the distances of the axes of rotation of the format cylinders and color cylinders from the axis of rotation of the impression cylinder. Each traversing device enables independent adjustment of a format cylinder and a color cylinder.
Nach der Erfindung weist die Verfahreinrichtung eine einzige, relativ zur Achse des Gegendruckzylinders ortsfeste, nicht drehbare Spindel auf, welche der Führung zweier unabhängig voneinander verfahrbarer Schlitten dient. In jedem Schlitten, welcher zur Lagerung des Farbzylinders bzw. des Formatzylinders vorgesehen ist, ist eine Spindelmutter gelagert, welche durch einen Elektromotor direkt antreibbar ist. Hierbei ist der Rotor des Elektromotors starr mit der Spindelmutter verbunden, beispielsweise durch eine Klemm- oder Schraubverbindung. Vorzugsweise handelt es sich bei dem Motor um einen Torquemotor.According to the invention, the shuttle has a single, relative to the axis of the impression cylinder stationary, non-rotatable spindle, which serves to guide two independently movable carriage. In each carriage, which is provided for storage of the ink cylinder or the format cylinder, a spindle nut is mounted, which is directly driven by an electric motor. Here, the rotor of the electric motor is rigidly connected to the spindle nut, for example by a clamping or screw connection. Preferably, the motor is a torque motor.
In bevorzugter Ausgestaltung ist der Rotor des Motors nicht mittels eines eigenen Rotativlagers, sondern ausschließlich über ein Rotativlager der Spindelmutter, vorzugsweise ein zweireihiges Schrägkugellager, drehbar gelagert. Damit ist sowohl ein sehr kompakter als auch ein spiel- und hysteresefreier Antrieb der Spindelmutter gegeben.In a preferred embodiment, the rotor of the motor is not rotatably supported by means of a separate Rotativlagers, but exclusively via a rotary bearing of the spindle nut, preferably a double-row angular contact ball bearings. Thus, both a very compact as well as a play and hysteresis-free drive the spindle nut is given.
Nach einer vorteilhaften Weiterbildung weist die Verfahreinrichtung eine Längenmesseinrichtung auf, welche als inkrementelles oder absolutes Messsystem ausgebildet sein kann. Statt einer direkten Positionsbestimmung des Schlittens ist auch eine indirekte Positionsbestimmung über eine Messung der Winkelposition der Spindelmutter-Rotor-Einheit möglich.According to an advantageous development, the traversing device has a length measuring device which can be designed as an incremental or absolute measuring system. Instead of a direct position determination of the carriage and an indirect position determination via a measurement of the angular position of the spindle nut-rotor unit is possible.
Die Verfahreinrichtung mit direkt angetriebener Spindelmutter hat den besonderen Vorteil, dass im Vergleich zu Verfahrsystemen, die mit mechanischen Übertragungsmitteln, etwa Zahnriemen, arbeiten, hohe Beschleunigungen und Verfahrgeschwindigkeiten sowie sehr kurze Reaktionszeiten realisierbar sind. Damit ist es möglich, die Verfahreinrichtung nicht nur beim Auswechseln von Zylindern, sondern auch zur aktiven Schwingungstilgung zu verwenden. Hierbei werden Schwingungen des Gegendruckzylinders mittels eines Sensors erfasst und die entsprechenden Signale an eine Steuereinrichtung weitergeleitet, welche die Verfahreinrichtung derart ansteuert, das ein auf die Spindelmutter des Linearantriebs des Format- und/oder Farbzylinders wirkendes Drehmoment der Schwingung des Gegendruckzylinders entgegenwirkt.The traversing device with directly driven spindle nut has the particular advantage that compared to traversing systems which work with mechanical transmission means, such as toothed belts, high accelerations and traveling speeds as well as very short reaction times can be realized. This makes it possible to use the shuttle not only when replacing cylinders, but also for active vibration damping. Here, vibrations of the impression cylinder are detected by means of a sensor and forwarded the corresponding signals to a control device which controls the traversing device, the one on the spindle nut counteracts the torque acting on the linear drive of the format and / or color cylinder of the oscillation of the impression cylinder.

Um die Position jeder einzelnen Achse A3 eines Formatzylinders 3 sowie jeder Achse A4 eines Farbzylinders 4 relativ zur Achse A2 des Gegendruckzylinders 2 einstellen zu können, ist eine Verfahreinrichtung 5 pro Paar an Zylindern 3, 4 vorhanden. Die Verfahreinrichtung 5 weist eine fest, beispielsweise mittels einer Klemmung 6, in einem Rahmen 7 angeordnete Spindel 8 auf. Diese Spindel 8 dient zusammen mit einer ebenfalls am Rahmen 7 befestigten Linearführung 9 der Führung von zwei Schlitten 10, 11, welche Lagerböcke des Formatzylinders 3 bzw. des Farbzylinders 4 bilden.Both the format cylinder 3 and the color cylinder 4 can be replaced if necessary.

Der elektrische Direktantrieb der Spindelmutter 20 durch den Torquemotor 16 ermöglicht es, die Kräfte, die zwischen den Zylindern 2, 3, 4, insbesondere zwischen dem Formatzylinder 3 und dem Gegendruckzylinder 2, wirken, sehr genau und schnell zu verändern. Diese Eigenschaft ist nutzbar, um Schwingungen des Gegendruckzylinders 2 aktiv zu unterdrücken. Hierbei werden Schwingungen des Gegendruckzylinders 2 mit einem Schwingungssensor 22 gemessen, der entsprechende Signale an eine Steuereinrichtung 23 leitet. Die Steuereinrichtung 23 dient der Ansteuerung des Torquemotors 16, womit Kräfte erzeugt werden, die in der Schwingung des Gegendruckzylinders 2 entgegenwirkender Weise auf den Formatzylinder 3 und/oder den Farbzylinder 4 wirken. Auf diese Weise ist ein geschlossener Regelkreis zur aktiven Schwingungstilgung realisiert.The electric direct drive of the spindle nut 20 by the torque motor 16 makes it possible to change the forces acting between the cylinders 2, 3, 4, in particular between the format cylinder 3 and the impression cylinder 2, very accurately and quickly.
