Abstract

The printing machine comprises at least two printing units for perfecting, which are arranged one after the other in the running direction of the printing carrier web and each have two plate cylinders and two blanket cylinders, the printing carrier web being guided between the latter. In order to avoid oscillations which lead to the impairment of the print, the longitudinal axes of the two blanket cylinders of one printing unit in projection are positioned at an angle relative to each other on a tangential plane placed through the printing line on one blanket cylinder. In this case, the longitudinal axes lie in planes parallel to the tangential plane. <IMAGE>

Description

Die Erfindung betrifft eine Rollenoffset-Rotationsdruckmaschine gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a web offset rotary printing press according to the preamble of patent claim 1.

Werden derartige Druckmaschinen mit hohen Produktionsgeschwindigkeiten betrieben, so treten durch Schwingungen bedingt Fehler im Druck auf. Es ist bereits vorgeschlagen worden, vergleiche deutsche Patentanmeldung F 3235 360 Schwingungen der Druckträgerbahn, die beim Abreißen der Bahn von den Gummizylindern auftreten, dadurch zu vermindern, daß die Bahn unter teilweiser Umschlingung eines Gummizylinders in ein Druckwerk einläuft und etwa senkrecht zu einer durch die Achsen der Gummizylinder gelegten Ebene ausläuft. Diese Anordnung wirkt jedoch nicht Fehlern im Druck entgegen, die durch Schwingungen beim harten Anlaufen der Gummizylinder nach Durchlauf der Zylindergruben entstehen, wie beispielsweise Grubenstreifen.If printing machines of this type are operated at high production speeds, errors in printing occur due to vibrations. It has already been proposed to compare German patent application F 3235 360 to reduce vibrations of the print carrier web, which occur when the web is torn off the rubber cylinders, in that the web runs into a printing unit while partially wrapping a rubber cylinder and approximately perpendicular to one through the axes the rubber cylinder expires level. However, this arrangement does not counteract printing errors that arise from vibrations when the rubber cylinders start up hard after passing through the cylinder pits, such as pit strips.

Der Erfindung liegt die Aufgabe zugrunde, eine Rollenoffset-Rotationsdruckmaschine der eingangs genannten Gattung so weiterzubilden, daß sowohl durch den Abriß der Bahn von den Gummizylindern entstehende Schwingungen der Druckträgerbahn, als auch von den Gummizylindern selbst herrührende Schwingungen, die zu Grubenstreifen führen, vermindert werden.The invention has for its object to develop a web offset rotary printing press of the type mentioned so that both the tearing of the web from the rubber cylinders vibrations of the print carrier web, as well as vibrations resulting from the rubber cylinders themselves, which lead to pit strips, are reduced.

Erfindungsgemäß wird diese Aufgdbe durch Anwendung der im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.According to the invention, this object is achieved by applying the features specified in the characterizing part of claim 1.

  • Fig.2 die erfindungsgemäß wesentlichen Teile in einem Schnitt gemäß der Linie II-II in Fig.1,
  • Fig.3 die erfindungsgemäß wesentlichen Teile eines zweiten Ausführungsbeispieles und
  • Fig.4 einen Schnitt entlang der Linie IV-IV in Fig.3.
Further features and advantages result from the following description of two exemplary embodiments with reference to the drawing. Show it
  • 1 shows a first embodiment in a schematic side view,
  • 2 shows the essential parts according to the invention in a section along the line II-II in FIG. 1,

  • 4 shows a section along the line IV-IV in Figure 3.

Fig.1 zeigt zwei hintereinander angeordnete Druckwerke 1, 2 einer Rollenoffset-Rotationsdruckmaschine. Das Druckwerk 1 umfaßt zwei Plattenzylinder 3, 4 und zwei Gummizylinder 5, 6 sowie Farb- und Feuchtwerke, die nicht dargestellt sind. Das Druckwerk 2 ist ebenso aufgebaut wie das Druckwerk 1 und umfaßt zwei Plattenzylinder 7, 8 und zwei Gummizylinder 9, 10, denen wiederum nicht dargestellte Farb- und Feuchtwerke zugeordnet sind. Zwischen den beiden Gummizylindern jedes Druckwerkes 1, 2 läuft eine Druckträgerbahn durch, die somit beidseitig, d.h. im Schön- und Widerdruck, mit je zwei Farben bedruckt werden kann.1 shows two printing units 1, 2 arranged one behind the other of a web offset rotary printing press. The printing unit 1 comprises two plate cylinders 3, 4 and two blanket cylinders 5, 6 as well as inking and dampening units, which are not shown. The printing unit 2 is constructed in the same way as the printing unit 1 and comprises two plate cylinders 7, 8 and two blanket cylinders 9, 10, which in turn are associated with inking and dampening units, not shown. Between the two rubber cylinders of each printing unit 1, 2, a print carrier web runs through, which is thus on both sides, i.e. in perfect and reverse printing, can be printed with two colors each.

Wie die Figuren 1 und 2 erkennen lassen, ist die gestrichelt dargestellte Langsachse 12 des Gummizylinders 5, in der Projektion auf eine durch die Drucklinie einer an diesen Zylinder gelegten tangentialen Ebene 11, die hier mit der Ebene der Druckträgerbahn zusammenfällt, schräg zur Längsachse 13 des Gummizylinders 6 gestellt. Die beiden Längsachsen 12, 13 liegen dabei, wie Fig.1 zeigt, in Ebenen 18, 19, die parallel zur tangentialen Ebene 11 verlaufen. Infolge der Schrägstellung der Längsachsen 12, 13 verläuft auch die Zylindergrube 14 des Gummizylinders 5, die die Spannmittel für das Gummituch aufnimmt, schräg zur Zylindergrube 15 des Gummizylinders 6. Das mit a bezeichnete Maß der Schrägstellung der Längsachsen 12, 13 ist dabei so gewählt, daß es in der Projektion der Längsachsen auf die tangentiale Ebene etwa 1 mm beträgt.As can be seen in FIGS. 1 and 2, the longitudinal axis 12 of the rubber cylinder, shown in broken lines, is 5, in the projection on a through the pressure line of a tangential plane 11 placed on this cylinder, which coincides here with the plane of the print carrier web, placed obliquely to the longitudinal axis 13 of the blanket cylinder 6. As shown in FIG. 1, the two longitudinal axes 12, 13 lie in planes 18, 19 which run parallel to the tangential plane 11. As a result of the inclination of the longitudinal axes 12, 13, the cylinder pit 14 of the rubber cylinder 5, which receives the tensioning means for the rubber blanket, also runs obliquely to the cylinder pit 15 of the rubber cylinder 6. The dimension of the oblique position of the longitudinal axes 12, 13, designated with a, is chosen so that that it is about 1 mm in the projection of the longitudinal axes onto the tangential plane.

Beim dargestellten Ausführungsbeispiel ist die Andruckkraft, die die beiden Gummizylinder 5, 6 auf die Druckträgerbahn 11 ausüben, in der Mitte am größten und fällt beiderseits zu den Stirnseiten der Zylinder ab. Infolgedessen kann die Druckträgerbahn an den Stirnseiten am leichtesten von den Gummizylindern abgezogen werden. Hierdurch wird ein von der Senkrechten zur Bahnlaufrichtung unter einem kleinen Winkel über die Zylinderreihe abweichender Abriß der Bahn von den Gummizylindern 5, 6 erreicht. Damit kann der Druckträgerbahn 11 die Neigung zum Schwingen genommen werden, so daß die Gefahr von Dubliererscheinungen vermindert wird. Durch die Schrägstellung der Längsachse des Gummizylinders 5 laufen weiterhin die Zylindergruben 14, 15 der beiden Gummizylinder 5, 6 nicht schlagartig über die ganze Breite zusammen, sondern etwas zeitlich versetzt. Dadurch werden der bisher auftretende Anlaufstoß gemindert und die daraus resultierenden Zylinderschwingungen reduziert, so daß auch die hierdurch ausgelösten Fehler im Druck, wie Grubenstreifen, vermindert werden. Den gleichen positiven Effekt bringt zusätzlich die Tatsache, daß auch kein schlagartiges Zusammenlaufen der Zylindergrube 14 mit der Zylindergrube des Plattenzylinders 3 erfolgt.In the exemplary embodiment shown, the pressing force which the two rubber cylinders 5, 6 exert on the pressure carrier web 11 is greatest in the middle and drops on both sides to the end faces of the cylinders. As a result, the print carrier web at the end faces is easiest to pull off the rubber cylinders. As a result, the web is torn from the rubber cylinders 5, 6 at a small angle across the row of cylinders from the vertical to the web running direction. The tendency to oscillate can thus be removed from the print carrier web 11, so that the risk of duplication phenomena is reduced. Due to the inclined position of the longitudinal axis of the blanket cylinder 5, the cylinder pits 14, 15 of the two blanket cylinders 5, 6 do not suddenly run together over the entire width, but are offset somewhat in time. As a result, the thrust that has occurred so far is reduced and the resulting cylinder vibrations are reduced, so that the errors in printing such as pit strips triggered thereby are also reduced. The same positive effect is additionally brought about by the fact that the cylinder pit 14 does not suddenly collide with the cylinder pit of the plate cylinder 3.

Um einem eventuell durch die Schrägstellung des Gummizylinders 5 hervorgerufenen Verlaufen der Bahn entgegenzuwirken, ist die Längsachse 16 des Gummizylinders 9, der die gleiche Seite der Druckträgerbahn 11 wie der Gummizylinder 5 bedruckt, in bezug zur Längsachse 17 des Gummizylinders 10 in entgegengesetzter Richtung schräggestellt. Die Einspannlänge der Bahn zwischen zwei Druckwerken hat deshalb auf der Antriebsseite ein anderes Maß als auf der Bedienungsseite, was ebenfalls schwingungshemmend wirkt.In order to counteract any runout of the web possibly caused by the inclination of the blanket cylinder 5, the longitudinal axis 16 of the blanket cylinder 9, which prints on the same side of the print carrier web 11 as the blanket cylinder 5, is inclined in the opposite direction with respect to the longitudinal axis 17 of the blanket cylinder 10. The clamping length of the web between two printing units therefore has a different dimension on the drive side than on the operator side, which also has an anti-vibration effect.

Das in Fig.3 dargestellte Druckwerk weist wiederum zwei Plattenzylinder 20, 21 und zwei Gummizylinder 22, 23 auf, denen nicht dargestellte Farb- und Feuchtwerke zugeordnet sind. Die Gummizylinder 22, 23 sind bei diesem Druckwerk so angeordnet, daß eine in Richtung des Pfeiles c durchlaufende Druckträgerbahn 24 den Gummizylinder 23 beim Einlauf und den Gummizylinder 22 beim Auslauf aus dem Druckwerk teilweise umschlingt. Bei dieser Anordnung ist die Längsachse 25 des Gummizylinders 22 in der Projektion auf die gestrichelt dargestellte, durch die Drucklinie an diesen Gummizylinder gelegte tangentiale Ebene 26 derart gegenüber der Längsachse 27 des Gummizylinder 23 schräggestellt, daß die beiden Längsachsen sich nicht in der Mitte der Gummizylinder, sondern im Bereich der einen Stirnseite kreuzen. Die Längsachsen 25, 27 liegen in zwei Ebenen 28, 29, die parallel zur tangentialen Ebene 26 verlaufen.The printing unit shown in FIG. 3 in turn has two plate cylinders 20, 21 and two blanket cylinders 22, 23, to which inking and dampening units, not shown, are assigned. The rubber cylinders 22, 23 are arranged in this printing unit such that a printing carrier web 24 running in the direction of arrow c partially wraps around the rubber cylinder 23 at the inlet and the rubber cylinder 22 at the outlet from the printing unit. In this arrangement, the longitudinal axis 25 of the blanket cylinder 22 is inclined in the projection onto the tangential plane 26 shown by the dashed line, which is placed on the blanket cylinder by the pressure line, in such a way that the two longitudinal axes are not in the center of the blanket cylinder, but cross in the area of one end. The longitudinal axes 25, 27 lie in two planes 28, 29 which run parallel to the tangential plane 26.

Im Betreib erfolgt bei diesem Druckwerk der Abriß der Druckträgerbahn 24 von dem die Bahn länger führenden Gummizylinder 22 nicht von beiden Seiten gleichzeitig beginnend, sondern von der einen Stirnseite her durchlaufend bis zur anderen Stirnseite, wodurch in gleicher Weise wie beim ersten Ausführungsbeispiel die Neigung der Druckträgerbahn zu Schwingungen gemindert wird. Auch hier erfolgt kein schlagartiges Zusammenlaufen der Zylindergrube des Gummizylinders 22 mit den entsprechenden Zylindergruben des Gummizylinders 23 und des Plattenzylinders 20, so daß auch insoweit dem Entstehen von Schwingungen entgegengewirkt wird. Dabei wirkt ebenfalls schwingungshemmend, daß die freie Einspannlänge bis zum nachfolgenden Druckwerk auf den Antriebs- und Bedienungszeiten unterschiedlich ist.In operation, in this printing unit the print carrier web 24 is torn off from the rubber cylinder 22, which guides the web longer, not simultaneously from both sides, but continuously from one end side to the other end side, which in the same way as in the first exemplary embodiment causes the inclination the print carrier web is reduced to vibrations. Again, there is no sudden convergence of the cylinder pit of the rubber cylinder 22 with the corresponding cylinder pits of the rubber cylinder 23 and the plate cylinder 20, so that the occurrence of vibrations is counteracted to this extent. It also has an anti-vibration effect that the free clamping length up to the subsequent printing unit is different on the drive and operating times.
