Description

Die Erfindung betrifft eine Stellvorrichtung für Fünfzylinder Druckwerke von Offset-Rotationsdruckmaschinen zum wahlweisen ein- oder beidseitigen Bedrucken eines Bedruckstoffes.The invention relates to an actuating device for five-cylinder printing units of offset rotary printing presses for optional printing on one or both sides of a printing material.

Aus der DE-PS 12 38 929 ist bereits für eine Fünfzylinder-Rotationsoffsetbogendruckmaschine eine Druckan- und -abstellvorrichtung mit einer getrennten Vorrichtung zum wahlweisen Verlagern eines der Gummituchzylinder vom Druckzylinder an den anderen Gummituchzylinder bekannt. Jedoch ist dort für die Umstellung vom zweifarbigen Schöndruck (2/0) auf einfarbigen Schön- und Widerdruck (1/1) eine aufwendige Steuerung erforderlich, bei der bei stehender Maschine nach Wegschwenken des dem einen Gummituchzylinder zugeordneten Plattenzylinders eine Bolzenkupplung aus einer Raststellung ausfährt, ein Ritzel einen Kurbelarm samt einer Flanschbüchse zunächst in eine um 90° gegenüber der Ausgangsstellung gedrehte Zwischenstellung bringt, der Bolzen hier wieder einrastet und sodann ein Hilfsantrieb betätigt wird, der den Gummituchzylinder in die richtige Zahneingriffsstellung zum angesteuerten Gegendruckzylinder bringt. Danach wird der Kupplungsbolzen erneut ausgerückt und die Umstellbewegung bis zum Erreichen der gewünschten Lage fortgesetzt, in der der Kupplungsbolzen in eine dritte Raststellung einrückt. Erst nach Druckanstellung mittels des Hydraulikzylinders kann dann der Druck in der anderen Druckart erfolgen. Dieser Umstellvorgang erfordert aufgrund der Abhängigkeit der Umstellbewegung von der Stellung der Bolzenkupplung einerseits und der dazu erforderlichen Lösung des An- und Abstellmechanismus' vom Umstellmechanismus andererseits umfangreiche Schalt- und Überwachungsmaßnahmen.From DE-PS 12 38 929 is already known for a five-cylinder rotary offset sheet printing machine a printing on and off with a separate device for selectively moving one of the blanket cylinders from the impression cylinder to the other blanket cylinder. However, there is a complex control required for the change from two-color face printing (2/0) to single-color perfecting (1/1). a pinion first brings a crank arm together with a flange sleeve into an intermediate position rotated by 90 ° with respect to the starting position, the bolt snaps back into place and then an auxiliary drive is actuated, which brings the rubber blanket cylinder into the correct tooth engagement position for the controlled impression cylinder. The coupling pin is then disengaged again and the changeover movement continues until the desired position is reached, in which the coupling pin engages in a third latching position. Only after the pressure has been adjusted by means of the hydraulic cylinder can the pressure be carried out in the other pressure type. Due to the dependency of the changeover movement on the position of the bolt coupling on the one hand and the solution of the switching mechanism of the changeover mechanism required for this purpose, this changeover process requires extensive switching and monitoring measures.

Die Aufgabe der Erfindung ist es, ein Fünfzylinder-Druckwerk einer Offset-Rotationsdruckmaschine mit einer einfachen Vorrichtung auszustatten, die die Möglichkeit der Umstellung vom einseitigen zum beidseitigen Bedrucken und die Möglichkeit der Abstellung von den beiden Druckpositionen sowie das Aufbringen des erforderlichen Anstelldruckes durch ein einziges Stellorgan mit einfachen Übertragungsmitteln schafft.The object of the invention is to provide a five-cylinder printing unit of a rotary offset printing press with a simple To equip device that creates the possibility of switching from one-sided to two-sided printing and the possibility of switching from the two printing positions and the application of the required contact pressure by a single actuator with simple transmission means.

Die Lösung dieser Aufgabe besteht in der Anwendung der Merkmale des Kennzeichens des Patentanspruchs 1. Gemäß der Erfindung wird als einziges Stellorgan für die Umstellung vom ein- auf beidseitigen Druck und umgekehrt und die An- und Abstellung in diesen beiden Druckpositionen eine Einheit aus zwei unmittelbar hintereinander angeordneten druckmittelbetätigten Zylindern verwendet, deren drei Hubstellungen, beide Zylinder eingefahren, ein Zylinder ein- und einer ausgefahren und beide Zylinder ausgefahren über eine Kolbenstange als Drehbewegung auf ein drehbar gelagertes erstes Getriebeglied übertragen werden, welches mit einem zweiten, auf einer Synchronwelle sitzenden Getriebeglied im Eingriff steht, das die Drehbewegung über ein Übertragungsgestänge auf die exzentrische Lagerbuchse des zu verstellenden Gummituchzylinders weitergibt und durch eine Verdrehung derselben die entsprechende Position des Gummituchzylinders herstellt. Eine solche integrierte Vorrichtung für das Umstellen und das An- und Abstellen gewährleistet bei einem Miminum an Aufwand unter Wegfall aller besonderen Kupplungs- und Überwachungseinrichtungen und ohne ein Wegschwenken des zugehörigen Plattenzylinders eine schnelle und sichere Positionierung des Gummituchzylinders für die gewünschte Druckart.The solution to this problem consists in the application of the features of the characterizing part of patent claim 1. According to the invention, the only actuator for the changeover from one-sided to two-sided printing and vice versa and the switching on and off in these two printing positions is a unit of two in immediate succession arranged pressure medium-actuated cylinders are used, the three stroke positions, both cylinders retracted, one cylinder extended and one extended and both cylinders extended via a piston rod as a rotary motion to a rotatably mounted first gear member, which engages with a second gear member seated on a synchronous shaft stands, which passes on the rotary movement via a transmission linkage to the eccentric bearing bush of the blanket cylinder to be adjusted and by rotating the same produces the corresponding position of the blanket cylinder. Such an integrated device for changing over and switching on and off ensures a quick and safe positioning of the blanket cylinder for the desired printing type with a minimum of effort, eliminating all special coupling and monitoring devices and without pivoting away the associated plate cylinder.

Das in den Zeichnungen dargestellte Fünfzylinder-Offsetdruckwerk, vorzugsweise für Offset-Rollenrotationsdruckmaschinen, besteht aus einem gemeinsamen Druckzylinder (1), den beiden Gummituchzylindern (2) und (3) sowie den Plattenzylindern (4) und (5). Beim Schöndruck nach Fig.1 sind beide Gummituchzylinder (2) und (3) an den gemeinsamen Druckzylinder (1) angestellt und bedrucken die um diesen herumgeführte Papierbahn (6) einseitig. Beim Schön- und Widerdruck nach Fig.2 wird der Gummituchzylinder (3) vom Druckzylinder (1) ab- und an den anderen Gummituchzylinder (2) angestellt und bedruckt unter Benutzung des anderen Gummituchzylinders (2) als Gegendruckzylinder die zwischen beiden hindurchgeführte Papierbahn (6) beidseitig. Der Druckzylinder (1) dient in diesem Falle nur der Weiterleitung der über ihn geführten Papierbahn (6), falls dies gewünscht ist. Der Gummituchzylinder (2) ist gelagert in einer Exzenterbuchse (7), die durch einen Hebel mit einer nicht näher gezeigten Einstellvorrichtung verbunden ist, und in einer zweiten exzentrischen Buchse (8), auf die zur An- und Abstellung über ein Gestänge (9) ein Stellorgan (10) wirkt.The five-cylinder offset printing unit shown in the drawings, preferably for offset web-fed rotary printing presses, consists of a common printing cylinder (1), the two blanket cylinders (2) and (3) and the plate cylinders (4) and (5). 1, both blanket cylinders (2) and (3) are placed against the common printing cylinder (1) and print the paper web (6) around them on one side. 2, the blanket cylinder (3) is moved from the impression cylinder (1) and placed on the other blanket cylinder (2) and prints on the paper web (6th) passed between the two using the other blanket cylinder (2) as an impression cylinder ) on both sides. In this case, the printing cylinder (1) only serves to forward the paper web (6) guided over it, if this is desired. The blanket cylinder (2) is mounted in an eccentric bushing (7), which is connected by a lever to an adjusting device (not shown in more detail), and in a second eccentric bushing (8), on which a rod (9) is used to switch it on and off. an actuator (10) acts.

Der Gummituchzylinder (3) ist gelagert in einer Exzenterbuchse (11), die durch einen Hebel mit einer nicht näher gezeigten Einstellvorrichtung verbunden ist, sowie in einer zweiten exzentrischen Buchse (12), an der zur Anstellung an den Gummituchzylinder (2) oder an den Druckzylinder (1) oder zum Abstellen von beiden ein Gestänge (13) angebracht ist, das mit seinem anderen Ende mit dem auf der Synchronwelle (14) gelagerten Getriebeglied (15) verbunden ist. Dieses steht mit einem weiteren Getriebeglied (16) in Eingriff, das über ein Übertragungsglied (17) mit dem die drei Positionen ansteuernden Stellorgan (18) verbunden ist.The blanket cylinder (3) is mounted in an eccentric bushing (11), which is connected by a lever to an adjusting device (not shown in more detail), and in a second eccentric bushing (12), on which the blanket cylinder (2) or the Pressure cylinder (1) or a rod (13) is attached for parking both, the other end of which is connected to the gear member (15) mounted on the synchronous shaft (14). This engages with a further gear element (16) which is connected via a transmission element (17) to the actuator (18) which controls the three positions.

Im ausgeführten Beispiel nach Fig.1 sind in der Druckstellung 2/0, d.h. zweifacher Schöndruck, beide Stufen des Stellorgans (18) eingefahren. Das Übertragungsgestänge (13) befindet sich gegenüber dem Mittelpunkt der das Getriebeglied (15) tragenden Synchronwelle (14) in gestreckter Lage oder wenige Winkelgrade darüber hinaus, so daß das Stellorgan (18) von rückwirkenden Lagerkräften der Exzenterbuchse (12) freigehalten wird. Das Ausfahren einer der beiden Stufen des Stellorgans (18) bewirkt durch eine Drehung des Getriebegliedes (16) eine Drehung um etwa 90° des Getriebegliedes (15); das Übertragungsgestänge (13) verdreht entsprechend die Exzenterbuchse (12) und der Gummituchzylinder (3) erreicht eine Mittellage, in der er weder den Druckzylinder (1) noch den anderen Gummituchzylinder (2) berührt.In the example shown in Fig. 1 in the printing position 2/0, i.e. double fine print, both stages of the actuator (18) retracted. The transmission linkage (13) is located opposite the center of the synchronizer shaft (14) carrying the gear member (15) in an extended position or a few degrees beyond, so that the actuator (18) is kept free from retroactive bearing forces of the eccentric bushing (12). The extension of one of the two stages of the actuator (18) causes a rotation of the gear member (16) by approximately 90 ° of the gear member (15); the transmission linkage (13) rotates the eccentric bushing (12) accordingly and the blanket cylinder (3) reaches a central position in which it does not touch the impression cylinder (1) or the other blanket cylinder (2).

Durch das Ausfahren der zweiten Stufe des Stellorgans (18) wird durch Weiterdrehung des Getriebegliedes (16) eine gegenüber der Druckstellung 2/0 um etwa 180° gedrehte Stellung des Getriebegliedes (15) bewirkt, wodurch das Übertragungsgestänge (13) erneut in eine gestreckte Lage oder wenige Winkelgrade darüber hinaus gerät und das Stellorgan (18) auch in dieser Druckposition 1/1 von rückwirkenden Lagerkräften der Exzenterbuchse (12) freigehalten wird.By extending the second stage of the actuator (18) by rotating the gear member (16), the gear member (15) is rotated by about 180 ° with respect to the pressure position 2/0, causing the transmission linkage (13) to return to an extended position or a few degrees of angle beyond and the actuator (18) is kept free from retroactive bearing forces of the eccentric bushing (12) in this printing position 1/1.

Die Umstellbewegung von Druckstellung 2/0 nach 1/1 kann durch gleichzeitiges Ausfahren beider Stufen des Stellorganes (18) auch ohne einen Halt in der Mittelstellung, in der der Gummituchzylinder (3) sowohl vom Druckzylinder (1) als auch vom Gummituchzylinder (2) abgestellt ist, erreicht werden.The changeover from printing position 2/0 to 1/1 can be carried out by simultaneously extending both stages of the actuator (18) without stopping in the middle position, in which the blanket cylinder (3) both from the impression cylinder (1) and from the blanket cylinder (2) is turned off can be achieved.

Die Synchronwelle (14) überträgt alle Umstellbewegungen auf die andere Maschinenseite; die Stellorgane (18) und (10) sind daher nur auf einer Seite erforderlich.The synchronous shaft (14) transmits all changeover movements to the other machine side; the actuators (18) and (10) are therefore only required on one side.

Die Verwendung des oberen oder des unteren Druckwerkes zur Erstellung von wechselnden Eindrucken ist mit der beschriebenen An-, Ab- und Umstellvorrichtung in Verbindung mit der An- und Abstellvorrichtung des anderen Gummituchzylinders (2) ebenfalls in vorteilhafter Weise möglich.The use of the upper or lower printing unit to create changing impressions is with the described on, off and changeover device in connection with the on and Parking device of the other blanket cylinder (2) also possible in an advantageous manner.

Die Stellorgane (10) und (18) können beispielsweise als Pneumatikzylinder oder Hydraulikzylinder ausgeführt sein, es sind jedoch ebensogut andere Antriebsarten denkbar.The actuators (10) and (18) can be designed, for example, as pneumatic cylinders or hydraulic cylinders, but other types of drive are equally conceivable.

Die in den Figuren 1 und 2 als Zahnsegmente ausgebildeten Getriebeglieder (15) und (16) sind ebenso in anderen Ausführungsformen denkbar, wie z.B. als Vollzahnräder, Kettenräder mit Kettentrieb, Zahnriemenscheiben mit Zahnriemen, wobei diese Aufzählung keinen Anspruch auf Vollzähligkeit erhebt.The gear members (15) and (16) designed as tooth segments in FIGS. 1 and 2 are also conceivable in other embodiments, such as e.g. as full gears, sprockets with chain drive, toothed belt pulleys with toothed belts, this list does not claim to be complete.
