Abstract

The interval or spacing between rotational axes of adjacent cylinders in a rotary printing press, between a print-on position and a print-off position is accomplished using eccentric bushings for the cylinder journals of at least one of the cylinders. A printing gap between the two cylinders can also be varied using separate eccentric bushings. The effective eccentricity of the bushings extends parallel to a line connecting the axes of rotation of the cylinders.

Die erste Zylinderbuchse 09 ist z. B. mittels eines Linearantriebes 16 um einen Stellwinkel α von 20 bis 30° , z. B. 25° aus einer Druck- An- Stellung A in eine Druck-Ab-Stellung B verschwenkbar (in Fig. 1 gestrichelt dargestellt).

B. einem doppelt wirkenden Druckluftzylinder bestehen, dessen freies Ende 18 der Kolbenstange über ein Gelenk 20 mit einer an der Seite der ersten exzentrischen Zylinderbuchse 09 befestigten Lasche 19 verbunden ist. Etwa 90 Grad zur Lasche 19 ist an der Seite der Zylinderbuchse 09 eine zweite Lasche 21 angeordnet, deren freies Ende als Auflager dient. Dieses Auflager wirkt in Druck-An-Stellung A mit einem seitengestellfesten Anschlag 22 zusammen. Dabei kann der Anschlag 22 z. B. als Gleitlager 22 ausgebildet sein.The first cylinder liner 09 is e.g. B. by means of a linear drive 16 by an angle α of 20 to 30 °, z. B. 25 ° from a pressure on position A into a pressure down position B (shown in dashed lines in Fig. 1). Here, the linear drive 16 from a pivotally mounted in the side frame working cylinder 17, z. B. consist of a double-acting pneumatic cylinder, the free end 18 of the piston rod is connected via a joint 20 with a bracket 19 attached to the side of the first eccentric cylinder bushing 09. About 90 degrees to the bracket 19, a second bracket 21 is arranged on the side of the cylinder liner 09, the free end of which serves as a support. This support cooperates in the print-on position A with a stop 22 fixed to the side frame. The stop 22 z. B. be designed as a slide bearing 22.
Die zweite Zylinderbuchse 12 ist z.

B. by means of a linear drive 24 by an adjustment angle β of about two to five degrees, for example three degrees from a wide position C of the pressure gap 06 into a narrow position D of the pressure gap 06.
Der Linearantrieb 24 kann z. B. aus einem am Seitengestell angelenkten und mittels Handrad 26 betätigbaren Gewinde-Spindelantrieb bzw. Schneckenantrieb 27 bestehen. Ein freies Ende 28 der Gewindespindel 29 bzw. des Schneckenantriebes 27 ist über ein Gelenk 30 mit einer an der Seite der zweiten exzentrischen Zylinderbuchse 12 befestigten Lasche 31 verbunden.The linear drive 24 can, for. B. consist of a hinged to the side frame and actuated by handwheel 26 threaded spindle drive or worm drive 27. A free end 28 of the threaded spindle 29 or of the worm drive 27 is connected via a joint 30 to a tab 31 fastened to the side of the second eccentric cylinder bush 12.
Die Anordnung arbeitet wie folgt: Durch Betätigen des Arbeitszylinders 17 und somit Verdrehen der ersten exzentrischen Zylinderbuchse 09 kann der Gummizylinder 01 von der Druck-An-Stellung A in die Druck-Ab-Stellung B verbracht werden (Fig. 1). Dabei wird zwischen den Gummizylindem 01 ; 04 der bisherige Druckspalt 06 in eine Druck-Ab-Position vergrößert und gleichzeitig zwischen den Gummizylinder 01 und Formzylinder 03 der Druckspalt 06 in eine Druck-Ab-Position vergrößert. Der Gummi- oder Gegendruckzylinder 04 kann ebenfalls mittels nicht dargestellter Exzenterbuchsen von einer Druck-An-Stellung G in eine Druck-Ab-Stellung H verstellt werden.The arrangement works as follows: By actuating the working cylinder 17 and thus rotating the first eccentric cylinder bushing 09, the rubber cylinder 01 can be moved from the pressure-on position A to the pressure-down position B (FIG. 1). It is between the rubber cylinders 01; 04 the previous printing gap 06 is enlarged in a printing-down position and at the same time the printing gap 06 is enlarged in a printing-down position between the blanket cylinder 01 and forme cylinder 03. The rubber or impression cylinder 04 can also be adjusted from a pressure-on position G to a pressure-down position H by means of eccentric bushes, not shown.
Infolge der Betätigung des Linearantriebes 24 für das Verstellen der zweiten exzentrischen Zylinderbuchse 12 kann in Druck-An-Stellung A des Gummizylinders 01 eine Veränderung der Weite des Druckspaltes 06, z. B. von - 50 μm bis + 100 μm, von der eingestellten Nulllage erzielt werden. Dies geschieht zwischen der Engstellung D und der Weitstellung C des Druckspaltes 06 (Fig. 2), z. B. zwischen + 50 μm.As a result of the actuation of the linear drive 24 for adjusting the second eccentric cylinder sleeve 12, a change in the width of the pressure gap 06, for. B. from - 50 microns to + 100 microns, can be achieved from the set zero position. This happens between the constriction D and the expansion C of the pressure gap 06 (Fig. 2), z. B. between + 50 microns.
Die Wirkungsrichtung der Exzentrizität f der zweiten Zylinderbuchse 12 verläuft in etwa parallel zu einer gedachten Verbindungslinie 32 zwischen der Rotationsachse 08 des Gummizylinders 01 und einer nicht dargestellten Rotationsachse des benachbarten Formzylinders 03.The direction of action of the eccentricity f of the second cylinder sleeve 12 runs approximately parallel to an imaginary connecting line 32 between the axis of rotation 08 of the blanket cylinder 01 and an axis of rotation of the adjacent forme cylinder 03, not shown.
Die Rotationsachsen 08 der Zylinder 01; 04 sind mit einer gedachten Verbindungslinie 33 verbunden.The axes of rotation 08 of the cylinder 01; 04 are connected with an imaginary connecting line 33.
Wenn der zwischen den Zylindern 01 ; 04 während der Druck-An-Stellung A bestehende Druckspalt 06 von einer Normalstellung O, z. B. für eine Grammatur von 80 g/m2 infolge einer verringerten Papierdicke in eine Engstellung D geändert werden soll, so wird der Linearantrieb 24 nach links bewegt (Fig. 2).If the between the cylinders 01; 04 existing during the print-on position A pressure gap 06 from a normal position O, z. B. for a grammage of 80 g / m 2 due to a reduced paper thickness in a narrow position D, the linear drive 24 is moved to the left (Fig. 2).
Soll eine Weitstellung C des Druckspaltes 06 erreicht werden, so wird der Linearantrieb 24 von der Normalstellung O in die Gegenrichtung bewegt.If a wide position C of the pressure gap 06 is to be reached, the linear drive 24 is moved from the normal position O in the opposite direction.
Während der Verstellung der exzentrischen zweiten Zylinderbuchse 12 um ihre Rotationsachse 13 mittels des Linearantriebes 24 wird die erste exzentrische Zylinderbuchse 09 sowie das Auflager 21 auf dem Gleitlager 22 verschoben. Die Rotationsachse 11 der ersten Zylinderbuchse 09 verändert ihre Lage O-C bzw. O-D parallel zu einer Einstellkurve 34 der Papierdicke, welche von der Rotationsachse 08 des Gummizylinders 01 bei der Veränderung der Papierdicke beschrieben wirdDuring the adjustment of the eccentric second cylinder liner 12 about its axis of rotation 13 by means of the linear drive 24, the first eccentric cylinder liner 09 and the support 21 are displaced on the slide bearing 22. The axis of rotation 11 of the first cylinder liner 09 changes its position OC or OD parallel to an adjustment curve 34 of the paper thickness, which is described by the axis of rotation 08 of the blanket cylinder 01 when the paper thickness changes
Jeder Punkt auf der Einstellkurve 34 hat in etwa den gleichen Abstand zur Rotationsachse des Formzylinders 03 und verändert diesen Abstand somit nicht, d. h. es verbleibt die Peripherie 02 des Gummizylinders 01 in der Nähe der Peripherie des Formzylinders 03.Each point on the setting curve 34 has approximately the same distance from the axis of rotation of the forme cylinder 03 and therefore does not change this distance, i. H. the periphery 02 of the blanket cylinder 01 remains in the vicinity of the periphery of the forme cylinder 03.
Unter annähernd parallel ist ein Öffnungswinkel zweier Geraden von ±10°, insbesondere von +5° zu verstehen. An approximately parallel opening angle of two straight lines is to be understood as ± 10 °, in particular + 5 °.
