Description
Gebiet der ErfindungTerritory of invention
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 The invention relates to a flexographic printing press with a central impression cylinder as well as these surrounding format and color cylinders. Furthermore The invention relates to a method for operating a flexographic printing machine.

Aufgabe der ErfindungTask of invention
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.Of the The invention has for its object to provide a flexographic printing machine, which in a simple structure a fast, accurate and from each other independent Adjustment of a format cylinder and a color cylinder allows. Furthermore, there is the task of the performance of a flexographic printing machine to improve.
Zusammenfassung der ErfindungSummary the invention
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 Tasks are performed by a flexographic press with the features of claim 1 and by a method for operating a flexographic printing machine solved with the features of claim 8. In the following context With the device mentioned embodiments and advantages apply accordingly also for the procedure and vice versa.
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 conventional manner a central Impression cylinder and a plurality of pairs each of a format cylinder and a color cylinder on. During operation of the flexographic printing machine lie the format cylinder on the impression cylinder and in turn contacted by one color cylinder. To change the distances the axes of rotation of the format cylinder and color cylinder of the axis of rotation the counter-pressure cylinder traversing devices are provided. Every moving device allows an independent one 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.To the invention, the shuttle a single, relatively to the axis of the impression cylinder stationary, non-rotatable spindle on which of the leadership two independent mutually movable carriage is used. In every sled, which intended for storage of the color cylinder or the format cylinder is, a spindle nut is supported, which by an electric motor is directly drivable. Here, the rotor of the electric motor is rigid connected to the spindle nut, for example by a clamping or screw connection. Preferably, the engine 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 preferred embodiment, the rotor of the motor is not by means a separate Rotativlagers, but exclusively via a Rotativlager the spindle nut, preferably a double-row angular contact ball bearings, rotatably mounted. This is both a very compact and a game and hysteresis-free Drive the spindle nut 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.To an advantageous development, the traversing a Length measuring device on, which is designed as an incremental or absolute measuring system can be. Instead of a direct position determination of the carriage is also an indirect position determination via a measurement of the angular position the spindle nut-rotor unit 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 Moving device with directly driven spindle nut has the particular advantage that compared with positioning systems with mechanical transmission means, such as toothed belts, work, high accelerations and travel speeds and very short reaction times can be realized. That's it possible, the shuttle not only when changing cylinders, but also to use for active vibration damping. in this connection be vibrations of the impression cylinder by means of a sensor detected and the corresponding signals to a control device forwarded, which drives the traversing such, the a on the spindle nut of the linear drive of the format and / or Color cylinder acting torque of the vibration of the impression cylinder counteracts.
