Description

Die Erfindung betrifft eine Bogen-Offsetrotationsdruckmaschine nach dem Fünfzylinder-System, mit einem die zu bedruckenden Bogen von einem Anleger übernehmenden Gegendruckzylinder, an den, in Transportrichtung der Bogen gesehen, hintereinander zwei Gummizylinder angestellt sind.The invention relates to a sheet-fed offset printing machine according to the five-cylinder system, with a counter-pressure cylinder which takes over the sheets to be printed from a feeder, on which, seen in the transport direction of the sheets, two blanket cylinders are placed one behind the other.

Eine Maschine dieser Art ist aus dem Fachbuch «Einführung in den Offsetdruck" von Wolfgang Walenski, Eggen-Fachbuchreihe, Seite 113, bekannt. Mit dieser Maschine kann ein Bogen auf einer Seite mit einem zweifachen Schöndruck bedruckt werden. Darüber hinaus zeigt die Seite 155 des gleichen Fachbuches eine Bogen-Offsetrotationsmaschine für Schön- und Widerdruck, bei der ein zu bedruckender Bogen zwischen zwei Gummizylindern hindurchgeführt wird, wobei ein Gummizylinder ein Greifersystem trägt. Jede dieser Maschinen ist also auf eine bestimmte Druckart festgelegt. Aus der DE-A-1 913 038 ist es auch bereits bekannt, durch den Offsetteil eines Gegendruckzylinders und mit Hilfe eines Übernahmezylinders sowie des einzufärbenden Plattenzylinders einen Widerdruck zu erzeugen, jedoch handelt es sich hier um ein komplexes Druckwerk.A machine of this type is known from the specialist book "Introduction to offset printing " by Wolfgang Walenski, Eggen specialist book series, page 113. With this machine, a sheet can be printed on one side with double face printing. In addition, page 155 of the In the same technical book, a sheet-fed offset rotary machine for face and back printing, in which a sheet to be printed is passed between two blanket cylinders, one blanket cylinder carrying a gripper system, so each of these machines is fixed to a specific type of printing 038 it is also already known to produce an impression by means of the offset part of a counterpressure cylinder and with the aid of a takeover cylinder and the plate cylinder to be inked, but this is a complex printing unit.

Aufgabe der Erfindung ist es, eine Bogen-Offsetrotationsdruckmaschine der eingangs bezeichneten Art ohne zusätzliche Raumbeanspruchung und insbesondere ohne eine Wendevorrichtung wahlweise im Bedarfsfall auf Widerdruck umschaltbar zu machen.The object of the invention is to make a sheet-fed offset rotary printing press of the type described at the outset without additional space requirements and in particular without a turning device optionally switchable to reverse pressure if necessary.

Diese Aufgabe wird durch die Anwendung der Merkmale des kennzeichnenden Teiles des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen und aus der Beschreibung in Verbindung mit den Zeichnungen. In diesen zeigen

  • Fig. 1 bis 3 den Grundaufbau der erfindungsgemäßen, umschaltbaren Bogen-Offsetrotationsdruckmaschine,
  • Fig. 4 bis 6 eine vorteilhafte Weiterbildung der erfindungsgemäßen Bogen-Offsetrotationsdruckmaschine und
  • Fig. 7 und 8 eine weitere Variante der Erfindung.
This object is achieved by applying the features of the characterizing part of claim 1. Advantageous further developments result from the subclaims and from the description in conjunction with the drawings. Show in these
  • 1 to 3 the basic structure of the switchable sheet-fed offset printing press according to the invention,
  • 4 to 6 an advantageous development of the sheet-fed offset printing press according to the invention and
  • 7 and 8 a further variant of the invention.

In den Darstellungen gemäß Fig. 1 bis 3 ist die Erfindung in der einfachsten Ausführungsform dargestellt. Einem Druckwerk 1 werden von einem Bogenanleger 2 die zu bedruckenden Bogen 3 zugeführt. Bei dieser Ausführungsvariante wird ein sogenannter doppelt großer Gegendruckzylinder 4 verwednet, der mit Greifern zur Übernahme der Bogen 3 ausgestattet ist. Die Hälfte des Umfanges des Gegendruckzylinders 4 ist mit einem Gummituch 5 versehen.1 to 3, the invention is shown in the simplest embodiment. A sheet feeder 2 feeds the sheets 3 to be printed to a printing unit 1. In this embodiment variant, a so-called double-sized impression cylinder 4 is used, which is equipped with grippers for taking over the sheet 3. Half of the circumference of the impression cylinder 4 is provided with a rubber blanket 5.

An den Gegendruckzylinder 4 ist ein erster Gummizylinder 6 angestellt, dem ein Plattenzylinder 7 zugeordnet ist. Hinter dem Gummizylinder 6 ist ein weiteres Zylinderpaar 8, 9 angeordnet, und zwar ein Plattenzylinder 8 und ein ebenfalls an den Gegendruckzylinder 4 anstellbarer Gummizylinder 9. Die im Druckwerk 1 bedruckten Bogen werden an einer Bogenabgabestelle beispielsweise einem Kettensystem 10 übergeben, durch das ein Weitertransport zu einem nachfolgenden Druckwerk oder zu einer Bogenauslage erfolgt.A first rubber cylinder 6, to which a plate cylinder 7 is assigned, is employed on the impression cylinder 4. A further pair of cylinders 8, 9 is arranged behind the blanket cylinder 6, specifically a plate cylinder 8 and a blanket cylinder 9 which can also be adjusted to the impression cylinder 4. The sheets printed in the printing unit 1 are transferred to a sheet delivery point, for example a chain system 10, through which a further transport takes place a subsequent printing unit or a sheet delivery.

Mit diesem Druckmaschinenkonzept ist es zum einen in herkömmlicher Weise möglich, die zu bedruckenden Bogen 3 in üblicher Weise um den Gegendruckzylinder 4 zu führen und nach der Aufbringung eines zweifachen Schöndruckes wieder aus dem Druckwerk 1 herauszuführen. In erfindungsgemäßer Weise ist eine Umstellung dieses Druckwerkes dadurch möglich, daß der Gummizylinder 6 ebenfalls mit einem Greifersystem ausgestattet wird, durch das ein zu bedruckender Bogen 3 von dem Gegendruckzylinder 4 übernommen wird und dieser Bogen 3 um den Gummizylinder 6 herumgeführt wird, wonach der Gegendruckzylinder 4, der in der Zwischenzeit eine halbe Umdrehung ausgeführt hat, wiederum den Bogen 3 übernimmt, und zwar in der Weise, daß dieser nunmehr auf dem Gummituch 5 zu liegen kommt.With this printing press concept, it is possible, in a conventional manner, to guide the sheets 3 to be printed in a conventional manner around the impression cylinder 4 and to lead them out of the printing unit 1 again after applying a double face print. In a manner according to the invention, a conversion of this printing unit is possible in that the blanket cylinder 6 is also equipped with a gripper system, through which a sheet 3 to be printed is taken over by the impression cylinder 4 and this sheet 3 is guided around the blanket cylinder 6, after which the impression cylinder 4 , who has made half a turn in the meantime, again takes over the sheet 3, in such a way that it now comes to rest on the rubber blanket 5.

Die Trennung zwischen den erwähnten Zylindern kann durch Abheben eines Zylinders erreicht werden oder ergibt sich bei ausreichend dicken Papierstärken automatisch, wenn kein Bogen geführt wird.The separation between the above-mentioned cylinders can be achieved by lifting a cylinder or, if the paper is sufficiently thick, it results automatically if no sheet is fed.

Während der Bogen 3 um den Gummizylinder 6 herumgeführt wurde, kann er an seiner Unterseite, die nunmehr bei der Herumführung um den Gummizylinder 6 nach außen zu liegen kommt, durch den Zylinder 6, der bei dieser Betriebsweise als DiLitho-Plattenzylinder arbeitet. Nach der erneuten Übergabe an den Gegendruckzylinder 4 wird der an der Unterseite bedruckte Bogen 3 an dem zweiten Gummizylinder 9 vorbeigeführt, wobei ein Schöndruck auf diesen aufgebracht wird. In erfindungsgemäßer Weise wird dabei während dieser Zeit der Zylinder 7 von dem Gummizylinder 6 geringfügig abgehoben, beispielsweise in der Größenordnung von 3/10 mm. Dadurch wird der Gummizylinder 6 nicht durch den DiLitho-Plattenzylinder 7 eingefärbt, wenn er keinen Bogen führt. Wie die Figuren 1 bis 3 erkennen lassen, ist eine Abstellung des zweiten Gummizylinders 9 vom Gegendruckzylinder nicht erforderlich, wenn der keinen Bogen tragende Umfangsbereich des Gegendruckzylinders 4 an dem Gummizylinder 9 vorbeigeführt wird, da in diesem Bereich mangels fehlender Auflage an sich kein Kontakt entstehen kann. Wird jedoch dieser Bereich beispielsweise ebenfalls in vorteilhafter Weise mit einem Gummituch belegt, sollte auch der Gummizylinder 9 geringfügig während dieser halben Umdrehung von dem Gegendruckzylinder 4 abgehoben werden, um gegebenenfalls ein nicht erwünschtes Einfärben dieses Bereiches des Gegendruckzylinders 4 durch den Gummizylinder 9 zu vermeiden.While the sheet 3 was guided around the rubber cylinder 6, it can pass through the cylinder 6 on its underside, which now comes to lie outside when it is being guided around the rubber cylinder 6, and in this operating mode works as a DiLitho plate cylinder. After the renewed transfer to the impression cylinder 4, the sheet 3 printed on the underside is guided past the second rubber cylinder 9, with a fine print being applied to the latter. In the inventive manner is then lifted slightly during this time, the cylinder 7 of the blanket cylinder 6 mm, for example in the order of 3/10 min. As a result, the rubber cylinder 6 is not colored by the DiLitho plate cylinder 7 if it does not lead to a sheet. As can be seen from FIGS. 1 to 3, it is not necessary to move the second rubber cylinder 9 away from the impression cylinder if the non-arched peripheral region of the impression cylinder 4 is guided past the rubber cylinder 9, since no contact can be made in this region due to the lack of a support . However, if this area is also advantageously covered with a rubber blanket, for example, the rubber cylinder 9 should also be lifted slightly from the impression cylinder 4 during this half revolution in order to avoid undesired coloring of this area of the impression cylinder 4 by the rubber cylinder 9.

Die Figuren 2 und 3 zeigen die diversen Zylinder des Druckwerkes 1 in verschiedenen Winkellagen, so daß der Verlauf der Führung des Bogens 3 erkennbar ist.Figures 2 and 3 show the various cylinders of the printing unit 1 in different angular positions, so that the course of the guide of the sheet 3 can be seen.

Eine vorteilhafte Weiterbildung der Erfindung ergibt sich aus den Figuren 4 bis 6, bei denen hinter der Bogenabgabestelle, beispielsweise an der Kette 10, ein DiLitho-Farb- und Feuchtwerk 12 verwendet wird. Gleichzeitig wird der Gegendruckzylinder 4 zusätzlich mit einer Platte 11 belegt. Beim Vorbeiführen der DiLithoplatte 11 an dem Farb- und Feuchtwerk 12 erfolgt eine Einfärbung, so daß der angelegte Bogen 3 mit einem Widerdruck versehen wird, wenn dieser anschließend um den Gegendruckzylinder 4 zur Bogenauslage geführt wird. Bei der erfindungsgemäßen Betriebsweise kann wiederum der zunächst von dem Gegendruckzylinder 4 übernommene Bogen an den ebenfalls mit Greifern ausgestatteten ersten Gummizylinder 6 übergeben werden und in der bereits beschriebenen Weise dabei einmal um den Gummizylinder herausgeführt werden. Ebenso wie bei der Betriebsweise gemäß Fig. 1 bis 3 wird bei der Ausführungsform gemäß Fig. 4 und 6 dem Druckwerk 1 jeweils nur ein Bogen über eine Umdrehung des Gegendruckzylinders zugeführt, so daß jeweils zwischen aufeinanderfolgenden anzulegenden Bogen eine Lücke vorhanden ist, deren Länge in etwa der Bogenlänge entspricht.An advantageous further development of the invention results from FIGS. 4 to 6, in which a DiLitho inking and dampening unit 12 is used behind the sheet delivery point, for example on the chain 10. At the same time, the opposite Printing cylinder 4 also covered with a plate 11. When the DiLithoplate 11 is guided past the inking and dampening unit 12, inking takes place, so that the sheet 3 created is provided with an impression when it is subsequently guided around the impression cylinder 4 to the sheet delivery. In the operating mode according to the invention, the sheet initially taken over by the impression cylinder 4 can again be transferred to the first rubber cylinder 6, which is also equipped with grippers, and can be guided around the rubber cylinder once in the manner already described. As in the mode of operation according to FIGS. 1 to 3, in the embodiment according to FIGS. 4 and 6 only one sheet is fed to the printing unit 1 over one revolution of the impression cylinder, so that there is a gap between successive sheets to be applied, the length of which in corresponds approximately to the arc length.

Wird nun der nächste Bogen 14 dem Gegendruckzylinder 4 zugeführt, so erfolgt die Aufbringung eines Widerdruckes durch die DiLitho-Druckplatte 11 (Fig. 4). Anschließend erfolgt die Übergabe des mit einem ersten Widerdruck versehenen Bogens 14 an den Gummizylinder 6 und dessen Vorbeiführung an dem Plattenzylinder 7. Dadurch wird in der bereits beschriebenen Weise ein Widerdruck aufgebracht, der hier den zweiten Widerdruck darstellt, der von der DiLitho-Platte 7 übertragen wurde. Danach erfolgt die zweite Übergabe an den Gegendruckzylinder 4 und die Vorbeiführung des Bogens an dem zweiten Gummizylinder 9, an dem der erste Schöndruck aufgebracht wird. Vorzugsweise sollte der zweite Gummizylinder 9 geringfügig vom Gegendruckzylinder 4 abgehoben werden, falls es unerwünscht ist, das Gummituch 5 (Fig. 2, 3) durch diesen einfärben zu lassen. Wie bereits erwähnt, taktet auch bei der Ausführungsform gemäß Fig. 4 bis 6 der Plattenzylinder 7 in der Zeit, in der der Gummizylinder 6 keinen Bogen führt.If the next sheet 14 is now fed to the impression cylinder 4, a back pressure is applied by the DiLitho printing plate 11 (FIG. 4). Subsequently, the sheet 14 provided with a first counterpressure is transferred to the rubber cylinder 6 and its passage past the plate cylinder 7. As a result, a counterpressure is applied in the manner already described, which here represents the second counterpressure transmitted by the DiLitho plate 7 has been. This is followed by the second transfer to the impression cylinder 4 and the passage of the sheet past the second rubber cylinder 9, to which the first printing is applied. Preferably, the second rubber cylinder 9 should be lifted slightly from the impression cylinder 4 if it is undesirable to have the rubber blanket 5 (FIGS. 2, 3) colored by it. As already mentioned, in the embodiment according to FIGS. 4 to 6, the plate cylinder 7 also cycles in the time in which the rubber cylinder 6 does not bend.

Die Darstellungen gemäß Fig. 7 und 8 zeigen eine Variante der erfindungsgemäßen Bogen-Offsetrotationsdruckmaschine. Das dargestellte Druckwerk 15 umfaßt einen ersten Gummizylinder 18 mit einem Plattenzylinder 19 sowie einen zweiten Gummizylinder 20 mit einem Plattenzylinder 21 und einem Ausleger 22, beispielsweise in Form einer Kette. Dem Druckwerk 15 werden von einem Bogenanleger 16 die zu bedruckenden Bogen 17 zugeführt. Zunächst werden die Bogen 17 von einem gemeinsamen Gegendruckzylinder 23 übernommen, der hier den gleichen Umfang aufweist wie die Gummizylinder 18 und 20. Auch hier wird der zu bedruckende Bogen wiederum zum Aufbringen eines Widerdruckes durch die Greifer des Gummizylinders 18 übernommen und an dem Plattenzylinder 19 vorbeigeführt, der in der beschriebenen Weise vom Gummizylinder 18 abgestellt ist, wenn dieser keinen Bogen führt. Anschließend erfolgt die erneute Übernahme des mit einem Widerdruck versehenen Bogens durch die Greifer des Gegendruckzylinders 23, wonach der Gegendruckzyl inder 23 die Bogen an dem zweiten Gummizylinder 20 vorbeiführt, durch den ein Schöndruck aufgebracht wird. Dann erfolgt die Auslage in bekannter Weise. In dem Ausführungsbeispiel gemäß Fig. und 8 ist es, zum Unterschied zu den vorangehend beschriebenen Ausführungsbeispielen, unbedingt erforderlich, daß auch der zweite Gummizylinder 20 von dem Gegendruckzylinder 23 abgehoben ist, wenn dieser keinen Bogen an dem Gummizylinder 20 vorbeiführt. Dadurch wird eine unerwünschte Einfärbung des Gegendruckzylinders 23 vermieden.7 and 8 show a variant of the sheet-fed offset printing press according to the invention. The printing unit 15 shown comprises a first blanket cylinder 18 with a plate cylinder 19 and a second blanket cylinder 20 with a plate cylinder 21 and a delivery arm 22, for example in the form of a chain. The sheet 15 to be printed is fed to the printing unit 15 from a sheet feeder 16. First, the sheets 17 are taken over by a common impression cylinder 23, which here has the same scope as the blanket cylinders 18 and 20. Again, the sheet to be printed is again taken up by the grippers of the blanket cylinder 18 to apply a counterpressure and is guided past the plate cylinder 19 , which is parked in the manner described by the blanket cylinder 18 when it does not bend. Subsequently, the gripping of the impression cylinder 23 takes over again the sheet provided with a counterpressure, after which the impression cylinder 23 guides the sheets past the second rubber cylinder 20, by means of which a surface pressure is applied. Then the display takes place in a known manner. In the exemplary embodiment according to FIGS. 8 and 8, in contrast to the exemplary embodiments described above, it is absolutely necessary that the second rubber cylinder 20 is also lifted off the impression cylinder 23 if the latter does not pass a sheet past the rubber cylinder 20. This prevents undesired coloring of the impression cylinder 23.
