Die Erfindung betrifft ein Verfahren und einen Antrieb für eine Verarbeitungsmaschine für Bogenmaterial. Die Erfindung eignet sich insbesondere für eine Verarbeitungsmaschine mit Druck- und/oder Lackwerken.The invention relates to a method and a drive for a processing machine for sheet material. The invention is particularly suitable for a processing machine with printing and / or coating plants.

Die genannten Lösungen eignen insbesondere für Zylinder deren Lage unveränderbar ist.Out
The solutions mentioned are particularly suitable for cylinders whose position is unchangeable.
Der Rotor des Einzelantriebs ist am Formzylinder angeordnet und konzentrisch zum Rotor ist der Stator des Einzelantriebs am Seitengestellt fixiert.
The rotor of the single drive is arranged on the forme cylinder and concentric to the rotor, the stator of the single drive is fixed at the side position.
Aufgabe der Erfindung ist es ein Verfahren und einen Antrieb der eingangs genannten Art derart zu verbessern, dass eine Einzelantriebslösung für einen lageveränderbaren Zylinder realisierbar ist, wobei zumindest die das Bogenmaterial führenden Zylinder über einen gemeinsamen Räderzug von einem Hauptantrieb antreibbar sind.The object of the invention is to improve a method and a drive of the type mentioned in such a way that a single drive solution for a variable position cylinder can be realized, wherein at least the sheet material leading cylinder can be driven via a common gear train of a main drive.
Die Aufgabe wird durch die Ausbildungsmerkmale von Anspruch 1 und 2 gelöst. Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.The object is solved by the training features of
Ein erster Vorteil ergibt sich daraus, dass das Verfahren und die Vorrichtung eine Antriebslösung gewährleisten, die insbesondere für zumindest einen Zylinder in einer Verarbeitungsmaschine geeignet ist, welcher mit einem Einzelantrieb gekoppelt und in seiner Lage, speziell seiner Achsposition, zu einem benachbarten Zylinder, speziell einem Bogenführungszylinder, veränderbar ausgebildet ist. Zylinder mit veränderbarer Achslage können als Gummituchzylinder in Druckwerken, insbesondere Offset- und/oder Flexodruckwerken und/oder Formzylinder in Flexound/oder Lackwerken ausgebildet sein. Derartige Zylinder sind von einem Hauptantrieb mit Räderzug mechanisch getrennt und eigenmotorisch direkt antreibbar.A first advantage results from the fact that the method and the device ensure a drive solution which is particularly suitable for at least one cylinder in a processing machine which is coupled to a single drive and in its position, especially its axis position, to an adjacent cylinder, especially one Sheet guiding cylinder, designed changeable. Cylinders with a variable axis position can be designed as blanket cylinders in printing units, in particular offset and / or flexographic printing units and / or forme cylinders in flexographic and / or coating units. Such cylinders are mechanically separated from a main drive with gear train and self-propelled directly by the motor.
Als zweiter Vorteil ist zu nennen, dass an wenigstens einem mittels Einzelantrieb antreibbaren, lageveränderbaren Zylinder ein Druckplattenwechsel erfolgen kann und der unmittelbar benachbarte, vom Hauptantrieb mit Räderzug antreibbare, beispielsweise Bogenführungszylinder in einem Lackwerk bzw. Flexodruckwerk, mittels einer Waschvorrichtung gleichzeitig oder phasenversetzt gereinigt werden kann. Alternativ kann beispielsweise während an wenigstens einem mittels Einzelantrieb gekoppelten, lageveränderbaren Zylinder ein Druckplattenwechsel erfolgt eine zugeordnete Dosiereinrichtung oder zugeordnete Walzen gereinigt und/oder gewechselt werden. Alternativ kann der einzeln antreibbare Zylinder (vorzugsweise mit Druckform) in Druck-ab Position mit einer ersten Umfanggeschwindigkeit gereinigt werden und der benachbarte Bogenführungszylinder kann - angetrieben vom Hauptantrieb - mit einer zweiten Umfangsgeschwindigkeit angetrieben werden. Weiterhin kann der antreibbare Zylinder (vorzugsweise mit Druckform) allein gereinigt werden. Hierzu sind Waschvorrichtungen bevorzugt mit einer Bürste oder einem Reinigungstuch einsetzbar.
In Druck-ab Position des einzeln antreibbaren Zylinders kann der zugeordnete Einzelantrieb gegebenenfalls stillgesetzt werden (momentenlos geschaltet). In Druck-ab Position kann am einzeln angetriebenen Zylinder beispielsweise das Gummituch gespannt oder gestrippt werden. Weiterhin kann in Druck-ab Position eine dem einzeln antreibbaren Zylinder zugeordnete Auftragwalze bzw. Rasterwalze eingerichtet werden oder der Walzenstreifen der Auftragwalze kann justiert werden oder die eingesetzte Rasterwalze kann gegen eine weitere Rasterwalze gewechselt werden. Zum Voreinfärben (einschließlich Lackieren) kann der einzeln antreibbare, lageveränderbare Zylinder mit zum Bogenführungszylinder höherer Umfangsgeschwindigkeit betrieben werden.
Somit sind mögliche Stillstandszeiten, beispielsweise beim Druckplattenwechsel vermeidbar und insgesamt durch zeitgleich oder phasenversetzt ablaufende Verfahrensschritte am jeweiligen Druck- bzw. Flexodruck-/ Lackwerk können Rüstzeiten verkürzt werden.It should be mentioned as a second advantage that a pressure plate change can take place on at least one cylinder which can be driven by means of a single drive, and the immediately adjacent one, which can be driven by the main drive with gear train, For example, sheet guiding cylinder in a coating unit or flexo printing unit, by means of a washing device can be cleaned simultaneously or out of phase. Alternatively, for example, during at least one position-variable cylinder coupled by means of a single drive, a printing plate change takes place, an associated metering device or associated rollers can be cleaned and / or changed. Alternatively, the individually drivable cylinder (preferably with printing form) may be cleaned in print-off position at a first peripheral speed, and the adjacent sheet-guiding cylinder may be driven at a second peripheral speed driven by the main drive. Furthermore, the drivable cylinder (preferably with printing form) can be cleaned alone. For this purpose, washing devices are preferably used with a brush or a cleaning cloth.
In pressure-from position of the individually drivable cylinder, the assigned individual drive can be stopped if necessary (switched torqueless). In pressure-off position, for example, the rubber blanket can be stretched or stripped on the individually driven cylinder. Furthermore, in pressure-off position, a mandrel or screen roller assigned to the individually drivable cylinder can be set up or the roller strip of the applicator roller can be adjusted or the screen roller used can be exchanged for another screen roller. For pre-inking (including painting), the individually drivable, variable-position cylinder can be operated with the sheet guiding cylinder higher peripheral speed.
Thus, possible downtime, for example, when changing the printing plate can be avoided and overall by simultaneously or out of phase running process steps at each printing or flexographic printing / coating unit setup times can be shortened.
Als dritter Vorteil kann aufgeführt werden, dass der zumindest eine lageveränderbare Zylinder in Druck-an Stellung sowie Druck-ab Stellung bewegbar ist. Alternativ kann ebenso eine zwischen Druck-an Stellung und Druck-ab Stellung liegende sanfte Druckbeistellung eingenommen werden. Beispielsweise ist diese Betriebsweise für nicht am Druck-/Lackierprozess beteiligte, lageveränderbare Zylinder geeignet zur Verbesserung der Bogenführung im Druck-/Lackspalt. Bei einer derartigen Lageveränderung des zumindest einen Zylinders, d.h. Veränderung der Achsposition zu einem benachbarten, das Bogenmaterial führenden und ortsfest gelagerten Zylinder, kann der am lageveränderbaren Zylinder angeordnete, gesamte Einzelantrieb bei diesen Veränderungen synchron mitbewegt werden. Weiterhin ist von Vorteil, dass der zumindest eine lageveränderbare Zylinder mittels des Einzelantriebs synchron oder asynchron zu dem benachbarten das Bogenmaterial führenden und ortsfest gelagerten Zylinder antreibbar ist oder bei Bedarf stillsetzbar ist (momentenlos geschaltet). Bei einer sanften Druckpressung (bei nicht am Druck-/Lackierprozess beteiligtem Zylinder) sind die Umfangsgeschwindigkeiten von einzeln angetriebenen Zylinder und Bogenführungszylinder annähernd synchron.As a third advantage can be listed that the at least one variable-position cylinder in the pressure-on position and pressure-off position is movable. Alternatively, a gentle Druckbeistellung between pressure-on position and pressure-off position can also be taken. For example, this mode of operation is not involved in the printing / coating process, variable position cylinder suitable for improving the bowing in the printing / lacquer gap. In such a change in position of the at least one cylinder, ie change in the axial position to an adjacent, the sheet material leading and stationarily mounted cylinder, the variable position arranged cylinder, entire single drive can be moved synchronously in these changes. Furthermore, it is advantageous that the at least one variable position cylinder by means of the single drive synchronously or asynchronously to the adjacent leading the sheet material and stationarily mounted cylinder is driven or shut down when needed (switched torqueless). In a soft pressure (in not involved in the printing / painting process cylinder), the peripheral speeds of individually driven cylinder and sheet guiding cylinder are approximately synchronous.
Ein vierter Vorteil liegt dahingehend vor, dass der einzeln angetriebene, lageveränderbare Zylinder auch schräg registert werden kann. Hierzu können die beiden Verstelleinrichtungen einzeln und unterschiedlich betätigt werden, so dass die Achsposition des einzeln angetrieben Zylinders die Achsposition des benachbarten Bogenführungszylinders in einem definierten Winkel schneidet.A fourth advantage is to the effect that the individually driven, variable position cylinder can also be registered obliquely. For this purpose, the two adjusting devices can be actuated individually and differently, so that the axial position of the individually driven cylinder intersects the axial position of the adjacent sheet guiding cylinder at a defined angle.
