Abstract
Description
Die Erfindung betrifft ein Verfahren zum Positionieren eines Plattenzylinders beim Plattenwechsel an bogenverarbeitenden Maschinen, insbesondere Bogendruckmaschinen, gemäß dem Oberbegriff des 1. Anspruchs und eine Vorrichtung gemäß dem Oberbegriff des 7. Anspruchs.The The invention relates to a method for positioning a plate cylinder when changing plates on sheet-processing machines, especially sheet-fed presses, according to the preamble of the first claim and a Device according to the preamble of the seventh claim.

Nachteilig an dieser Lösung ist, dass jeder Plattenzylinder vom Hauptantrieb in die richtige Plattenwechselposition gedreht werden muss. Es kann somit nur jeweils ein einziger Plattenzylinder in eine exakte Plattenwechselposition gebracht werden, wodurch sich längere Rüstzeiten ergeben.adversely At this solution is that every plate cylinder from the main drive must be rotated in the correct plate change position. It can thus only one single plate cylinder in an exact plate change position be brought, resulting in longer setup times result.

Nachteilig an dieser Lösung ist, dass die Einstellung des Korrekturwinkels über das Umfangsregister einen erhöhten Aufwand darstellt. Bei jedem Einstellen des Korrekturwinkels eines jeden Plattenzylinders bei jedem Positionieren wird von der Druckmaschine unnötig Energie verbraucht.adversely At this solution is that the adjustment of the correction angle over the circumferential register represents an increased expense. at each setting of the correction angle of each plate cylinder with each positioning becomes unnecessary from the printing press Energy consumed.

Neben einigen Vorteilen besitzen Direktantriebe auch Nachteile. So ist eine genaueste Synchronisation der einzelnen Antriebe erforderlich, wobei viele Sensoren und Kabelverbindungen in der Maschine untergebracht werden müssen. Direktantriebe erfordern einen hohen Aufwand und sind somit kostenintensiv. Für preisgünstigere Druckmaschinen sind Direktantriebe daher nicht einsetzbar. Nebenbei werden die Gummizylinder weiterhin von Schwenkvorrichtungen bewegt, die den Gummizylinder zwischen der Druck-an-Position und der Druck-ab-Position stellen.Next Some advantages have direct drives also disadvantages. So is a precise synchronization of the individual drives required with many sensors and cable connections housed in the machine Need to become. Direct drives require a lot of effort and are thus costly. For less expensive Printing presses are therefore direct drives can not be used. Beyond that the blanket cylinder continues to be moved by pivoting devices which the blanket cylinder between the pressure-on position and the pressure-off position put.

Nachteilig an dieser Lösung ist, dass die die Druck-Ab-Stellung des Zylinders begrenzenden Anschläge nur als Endlagendämpfer fungieren und keine Positionierung des Plattenzylinders zum Plattenwechsel vorgenommen wird. Diese Anschläge sind auch nicht einstellbar ausgebildet, so dass eine Lageeinstellung der Zylinder in der Druck-Ab-Stellung nicht möglich ist.adversely At this solution is that the pressure off position of the Cylinder limiting stops only as an end shock absorber act and no positioning of the plate cylinder for plate change is made. These attacks are not adjustable formed, so that a position adjustment of the cylinder in the pressure-off position is not is possible.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren anzugeben, welches mit vorhandenen Mitteln eine schnelle und sichere Korrektur der Winkelpositionsfehler der Plattenzylinder ermöglicht.Of the The invention is therefore based on the object of specifying a method which with existing means a fast and safe correction of the Angular position error of the plate cylinder allows.
Erfindungsgemäß wird die Aufgabe durch ein Verfahren mit den Merkmalen des 1. Anspruchs und eine Vorrichtung mit den Merkmalen des 7. Anspruchs gelöst.According to the invention the task by a method having the features of the first claim and a device having the features of the seventh claim solved.
Die Erfindung hat den Vorteil, dass mit bereits vorhandenen und zur Druck-an-und-ab-Stellung des Gummizylinders nötigen Mitteln eine genaue Einstellung der Winkelposition der Plattenzylinder möglich ist. Eine bevorzugte Ausführungsform der Erfindung hat den Vorteil, dass die schon vorhandenen Anschläge nur einstellbar ausgebildet werden müssen und sowohl zur Plattenzylinderpositionierung als auch zur Endlagendämpfungen der Positionierantriebe genutzt werden können, wodurch der Aufprall der Exzenterhebel minimiert wird. Individuelle und systematische Winkelfehler, die z. B. von Toleranzen der Zahnräder des Antriebszahnräderzuges herrühren können, werden durch die einmalig nach dem Aufstellen der Druckmaschine einzustellenden Anschläge kompensiert. Vorteilhafterweise kommt die Kompensation der Winkelfehler schon beim Zusammenrücken der Aggregate zur Anwendung, ohne dass elektronische Hilfsmittel nötig sind. Die sich zwischen den Druckwerken ergebenden Winkelfehler haben somit keine Auswirkung auf die genaue Winkelpositionierung der Plattenzylinder beim Plattenwechsel. Das Verfahren ist mit geringem Aufwand realisierbar und nur einmalig nötig, wodurch ein wirtschaftlicher Vorteil entsteht. Besonders bei langen Maschinen kann das Verfahren zur gezielten Kompensation der oben genannten Fehler genutzt werden.The invention has the advantage that with existing and necessary for the pressure-on-and-off position of the blanket cylinder means an accurate adjustment of the angular position of the plate cylinder is possible. A preferred embodiment of the invention has the advantage that the already existing stops must be formed only adjustable and both Plattenplattenpositionposition tion as well as the end position damping of the positioning can be used, whereby the impact of the eccentric lever is minimized. Individual and systematic angle errors, the z. B. can originate from tolerances of the gears of the drive gear train are compensated by the one time after setting up the printing press stops. Advantageously, the compensation of the angular errors comes already when the aggregates are brought together, without the need for electronic aids. The angular errors resulting between the printing units thus have no effect on the exact angular positioning of the plate cylinders during plate changing. The process can be implemented with little effort and only once necessary, resulting in an economic advantage. Especially with long machines, the method can be used for targeted compensation of the above errors.
