Description
Die Erfindung bezieht sich auf eine Offsetrotations-Bogendruckmaschine mit mehreren Druckwerken in Reihenbauweise für den Mehrfarbendruck, bei der die hintereinander angeordneten Druckwerke um einen Phasenwinkel zueinander versetzt und zwischen den Druckwerken jeweils mindestens ein Umführzylinder angeordnet ist.The invention relates to a Offset rotary sheet-fed printing machine with several printing units in series for multi-color printing, in which the printing units arranged one behind the other by a phase angle offset from each other and between each printing unit at least one transfer cylinder is arranged.
Der Phasenwinkel ist dabei als derjenige Winkel zwischen den Druckwerken definiert, um den gleiche Druckereignisse, zum Beispiel Druckanfang, Druckende, Kanalüberrollung, Farbhebereinsatz und Kurvenmomente, bezogen auf den eintourig drehenden Zylinder, im Vergleich zu den Nachbardruckwerken versetzt einsetzen. Durch diese und andere Parameter werden in den Druckwerken Schwingungen in einem breiten Spektrum initiiert und unerwünschte Schwingungsfrequenzen der Druckmaschine mit nachteiligem Einfluß auf die Druckqualität hervorgerufen. Besonders starke Anregungen der Maschineneigenfrequenzen gehen von den für die Greifersteuerung benötigten Kurvenmomenten in den papierführenden Zylindern aus, die zu Druckstörungen, wie Dublieren oder Übergabepasserfehler, führen.The phase angle is the angle between the Printing units defined to the same printing events to Example print start, print end, channel rollover, Ink lifter insert and cornering moments, based on the single-speed rotating cylinder, compared to the neighboring printing units use offset. Through this and other parameters A wide range of vibrations in the printing units initiated and unwanted vibration frequencies of the Printing machine with an adverse impact on print quality evoked. Particularly strong suggestions from the Machine natural frequencies go from those for Gripper control required cornering moments in the paper-guiding cylinders leading to pressure disturbances, such as Duplication or transfer register errors.
Eine Vorgabe für einem Winkel α in einer Druckmaschine ist aus der DE-OS 40 32 442 bekannt. Es handelt sich um die Festlegung des Winkels zwischen dem Druckzylinder und dem Übergabezylinder derart, daß die Konstellation der Plattenzylinder bei unterschiedlicher Anzahl von Übergabetrommeln zwischen benachbarten Druckzylinder stets gleich ist. Es werden 18 oder 54° bei einfach großen Platten- und Gummizylindern bzw. doppeltgroßen Druckzylinder und dreifach großen Übergabezylinder für diesen Winkel vorgeschlagen, um dadurch einen Schön- und Widerdruck mit einer Druckmaschine konstruktiv einfach realisieren zu können. A default for an angle α in a printing press is known from DE-OS 40 32 442. It is the Determination of the angle between the impression cylinder and the Transfer cylinder such that the constellation of the Plate cylinder with different number of Always transfer drums between adjacent printing cylinders is equal to. There are 18 or 54 ° for simply large plate and Rubber cylinders or double-sized impression cylinders and triple-sized transfer cylinders for this angle proposed to thereby have a perfecting with to be able to implement a printing press in a structurally simple manner.
Aus der DE-OS 32 03 879 ist eine Offsetrotations-Bogendruckmaschine besonderer Bauart mit hintereinander angeordneten Druckwerken, jedoch ohne Umführzylinder zwischen den Druckwerken, bekannt, wobei der Druckzylinder des Druckwerks am Gummituchzylinder des benachbarten Druckwerks anliegt. Bei dieser Anordnung ist zwischen den Verbindungslinien der Achsen der Gummituchzylinder und der Druckzylinder jeweils benachbarter Druckwerke ein Winkel zwischen 70 und 175° vorgesehen. Dieser Winkel ergibt sich in Verbindung mit konstruktiven Maßnahmen zur Verringerung der Zahl der für den Bogentransport benötigten Bauteile.From DE-OS 32 03 879 is one Offset rotary sheet printing machine of a special design with printing units arranged one behind the other, but without Transfer cylinder between the printing units, known, the Printing cylinder of the printing unit on the blanket cylinder of the adjacent printing unit is present. With this arrangement between the connecting lines of the axes of the Blanket cylinder and the impression cylinder each adjacent Printing units provided an angle between 70 and 175 °. This Angle results in connection with constructive measures to reduce the number of for sheet transport required components.
Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Reduzierung der Maschinenschwingungen zur Verringerung von dadurch bedingten Druckstörungen durch eine Phasenwinkelanordnung möglichst ohne konstruktive Bauteiländerung zu erreichen.The invention is based on the object, a Reduction of machine vibrations to reduce resulting pressure disturbances by a Phase angle arrangement if possible without constructive To achieve component change.
Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, daß
in Mehrfarbendruckmaschinen mit mehreren Druckwerken in
Reihenbauweise und zwischen den Druckwerken angeordneten
Umführzylindern die Druckwerke um einen Phasenwinkel gemäß
Patentanspruch 1 zueinander versetzt angeordnet sind.The inventive solution to this problem is that
in multicolour printing machines with several printing units in
Row construction and arranged between the printing units
Transfer cylinders according to the printing units by a
Weil aufgrund von Toleranzen eine exakte Synchronisation schwierig ist, kann ein Bereich von jeweils plus bzw. minus zwei Grad Phasenwinkel, ausgehend von den Nenn-Phasenwinkeln 90°, 120°, 180°, noch zugelassen werden. Gegenüber den exakten Winkeln , Nenn-Phasenwinkeln, zeigen Phasenwinkel aus diesem Bereich ein schlechteres Verhalten bezüglich Maschinendynamik. Allerdings zeigen diese Winkel noch ein deutlich günstigeres Verhalten im Vergleich zu beliebig gewählten Phasenwinkeln. Because an exact synchronization due to tolerances A range of plus or minus can be difficult two degrees phase angle, based on the nominal phase angles 90 °, 120 °, 180 °, are still allowed. Compared to the exact angles, nominal phase angles, show phase angles worse behavior in this area Machine dynamics. However, these angles still show significantly cheaper behavior compared to any selected phase angles.
Durch diese Maßnahme wird erreicht, daß Störquellen, wie zum Beispiel Kurvenereignisse für die Greifersteuerung eines papierführenden Zylinders, in wenigstens zwei Druckwerken zeitgleich einsetzen und synchron ablaufen. Im Mittel werden somit die für die Druckqualität schädliche Maschinengrundschwingung (erste Eigenform der Drehschwingung) sowie höhere Eigenschwingungen über einen großen Druckgeschwindigkeitsbereich am wenigsten angeregt. Damit lassen sich Druckstörungen, deren Ursache in der Maschinendynamik begründet ist, vermindern.This measure ensures that sources of interference, such as Example curve events for the gripper control of a paper-guiding cylinder, in at least two printing units Use at the same time and run synchronously. Become on average thus harmful to print quality Machine fundamental vibration (first mode shape of the torsional vibration) as well as higher natural vibrations over a large one Least excited print speed range. In order to can be pressure disorders, the cause of which in the Reduce machine dynamics.
Erreicht wird aber auch eine Verkürzung der Rüstzeiten bei der Maschineneinrichtung, weil wenigstens zwei, gegebenenfalls aber auch mehr Druckwerke, zum Beispiel jedes zweite Druckwerk einer halbtourigen Druckmaschine, in der gleichen Position stehen. Findet beispielsweise der Druckanfang bei einem Phasenwinkel von 90° im n-ten Druckwerk statt, setzen im Druckwerk n+4 die gleichen Druckereignisse zeitgleich ein und laufen dann synchron ab. Ein Phasenwinkel von 120° synchronisiert die Abläufe gleicher Druckereignisse im n-ten Druckwerk und im Druckwerk n+3; und ein Phasenwinkel von 180° synchronisiert die Abläufe im n-ten Druckwerk und in den Druckwerken n+2, n+4,n+6, usw. Im letzteren Falle liegen die Kanäle des Platten- und des Gummituchzylinders des einen Druckwerkes aufeinander, während die Kanäle des Platten- und des Gummituchzylinders im benachbarten Druckwerk sich gegenüberliegen.A reduction in set-up times is also achieved the machine equipment because at least two, but possibly also more printing units, for example each second printing unit of a half-speed printing press, in which stand in the same position. For example, if Start of printing at a phase angle of 90 ° in the nth printing unit instead, the same printing events are set in the printing unit n + 4 at the same time and then run synchronously. A phase angle of 120 ° synchronizes the processes of the same print events in the nth printing unit and in the printing unit n + 3; and a phase angle of 180 ° synchronizes the processes in the nth printing unit and in the printing units n + 2, n + 4, n + 6, etc. In the latter case the channels of the plate and blanket cylinder of one Printing unit on each other, while the channels of the plate and of the blanket cylinder in the neighboring printing unit itself opposite.
Bei einer halbtourigen Druckmaschine, bei der die
Druckzylinder und die Umführzylinder gegenüber dem
Plattenzylinder halbtourig drehen, läßt sich zwischen dem
Phasenwinkel und einem von der Verbindungslinie der Achse des
Druckzylinders und der Achse des Umführzylinders mit der
Waagerechten eingeschlossenen Winkel alpha herstellen. Es
gilt dann die Beziehung, daß der Phasenwinkel achtmal so groß
ist, wie dieser eben definierte Winkel. Ebenso ergibt sich
bei Druckmaschinen mit einem halbtourigen Druckzylinder und
einem dritteltourigen Umführzylinder die Beziehung, daß der
Phasenwinkel zehnmal so groß wie der Winkel zwischen der
Verbindungslinie Druckzylinderachse - Umführzylinderachse und
der Waagerechten ergänzt um den Quotienten 1 durch 180° ist.With a half-speed printing press, where the
Pressure cylinder and the transfer cylinder opposite the
Turn the plate cylinder half-speed, can be between the
Phase angle and one of the connecting line of the axis of the
Printing cylinder and the axis of the transfer cylinder with the
Create a horizontal enclosed angle alpha. It
then the relationship holds that the phase angle is eight times as large
is like this angle just defined. It also results
in printing presses with a half-speed printing cylinder and
a third-speed transfer cylinder the relationship that the
Phase angle ten times the angle between the
Connection line pressure cylinder axis - transfer cylinder axis and
the horizontal is supplemented by the
