Abstract

A series-produced sheet-fed offset rotary press having drum transfer systems in which sheet conveyance is carried out entirely through mechanical gripper transfers from a first impression cylinder to a transfer cylinder, then successively to a double-size transfer drum, then to a turning cylinder and then to a second impression cylinder and which are selectively engageable for multi-color printing on one side or alternately for perfecting printing and wherein, to change over sheet movement between these two operational modes the double-size transfer drum is selectively movable into one of two positions and is variable in its direction of rotation, the double-size transfer drum being engageable, in the first position and first direction of rotation and with the transfer cylinder disengaged, with two double-size impression cylinders for one-sided multi-color printing; while, in a second position and in the second direction of rotation, for perfecting, the double-size transfer drum can be lowered into engagement with the turning cylinder and the previously disengaged transfer cylinder can be lowered into engagement with the first double-size impression cylinder and with the double-size transfer drum; and wherein the distance between the impression cylinders is less than the diameter of the double-size transfer drum.

Description

Die Erfindung betrifft eine Bogenoffsetrotationsdruckmaschine in Reihenbauweise nach dem Oberbegriff des ersten Patentanspruchs.The invention relates to a sheet-fed offset rotary printing press in series construction according to the preamble of the first claim.

Eine Bogenoffsetrotationsdruckmaschine genannter Art ist z.B. aus der DE-C 1 107 246 bekannt. Bei Einstellung dieser Druckmaschine auf Schön- und Widerdruck erfassen am Umfang des Wendezylinders vorgesehene Greifer für Schön-und Widerdruck die nachlaufende Bogenkante und nehmen sie vom vorhergehenden doppelt großen Übertragungszylinder ab. Die Greifer schwenken dann um ihre eigene Achse nach innen bis zur Anlage an einem inneren Anschlagelement. Am Umfang des Wendezylinders zusätzlich vorgesehene Zweifarben-Greifer für Zweifarbendruck schwenken ebenfalls um ihre eigene Achse nach innen bis zur Anlage an ein anderes inneres Anschlagelement. Die nachlaufende Bogenkante wird von den nach innen geschwenkten Schön- und Widerdruckgreifern an die damit fluchtenden Zweifarben-Greifer übergeben, so daß der Bogen gewendet wird, wobei die nachlaufende Kante des Bogens jetzt vorlaufende Kante wird. Mit den durchgehend mechanischen Greiferübergaben dieser bekannten Druckmaschine, ist die Erfassung, Übertragung und Abgabe jedes Bogens immer exakt gleichmäßig, so daß die erforderliche Registerhalterung gewährleistet ist. Bei der genannten bekannten Maschine sind zusätzlich Sauger am Umfang des Wendezylinders vorgesehen und zwar in Drehrichtung des Wendezylinders hinter den Greifern. Diese Sauger halten zusätzlich die nachlaufende Bogenkante fest. Der Nachteil bei dieser bekannten Bogenoffsetrotationsdruckmaschine ist, daß wegen der starken Krümmung des Bogens auf den einfach großen Übertragungszylindem und wegen der mehrfachen Krümmungswechsel sowie einer Vielzahl von Greiferübergaben ein unsanfter Bogenlauf und Probleme bei der Registerhalterung im einseitigen Mehrfarbendruck auftreten können, sobald bei höheren Arbeitsgeschwindigkeiten gedruckt wird und steife Druckträger wie z.B. Karton verarbeitet werden sollen. Beim einseitigen Mehrfarbendruck können hier auch nur die niedrigen Arbeitsgeschwindigkeiten angewendet werden, wie sie beim Schön- und Widerdruck üblich sind.A sheet offset rotary printing machine of the type mentioned is e.g. known from DE-C 1 107 246. When this printing machine is set to face and back printing, grippers provided on the circumference of the turning cylinder for back and front printing grasp the trailing sheet edge and remove it from the previous double-sized transfer cylinder. The grippers then swivel inward about their own axis until they rest against an inner stop element. Two-color grippers for two-color printing, which are additionally provided on the circumference of the turning cylinder, also pivot inward about their own axis until they rest against another inner stop element. The trailing edge of the sheet is transferred from the inward and outward-facing grippers to the two-color grippers that are aligned with it, so that the sheet is turned, the trailing edge of the sheet now becoming the leading edge. With the continuous mechanical gripper transfers of this known printing machine, the detection, transmission and delivery of each sheet is always exactly uniform, so that the required register holder is guaranteed. In the known machine mentioned, suction cups are additionally provided on the circumference of the turning cylinder, namely in the direction of rotation of the turning cylinder behind the grippers. These suction cups also hold the trailing sheet edge. The disadvantage of this known sheet-fed offset printing press is that due to the strong curvature of the sheet on the simply large transfer cylinders and because of the multiple changes of curvature and a large number of gripper transfers, rough sheet running and problems with register holding in single-sided multi-color printing can occur as soon as printing is carried out at higher working speeds and stiff pressure carriers such as Cardboard to be processed. With single-sided multi-color printing, only the low working speeds can be used, as are common for face and reverse printing.

Es ist zwar aus der DE-B 2 305 132 bereits eine Rotationsdruckmaschine in Reihenbauweise bekannt, bei der die Bogen mittels durchgehender mechanischer Greiferübergaben von einem ersten doppelt großen Druckzylinder zu einer einzigen doppelt großen Übertragungstrommel und von dort zum zweiten doppelt großen Druckzylinder transportierbar sind. Mit dieser Rotationsdruckmaschine wird bei einseitigem Mehrfarbendruck zwar ein sanfter Bogenlauf erreicht, aber bei Schön- und Widerdruck ist von Nachteil, daß im Übergabebereich der doppelt großen Übertragungstrommel zusätzlich taktmäßig steuerbare Blas- und Saugkästen vorgesehen werden müssen, um ein Abschmieren des Bogens an der Trommel, insbesondere des Bogenendes nach dem Wendevorgang, zu verhindern.From DE-B 2 305 132 a rotary printing press in series construction is already known, in which the sheets can be transported by means of continuous mechanical gripper transfers from a first double-sized printing cylinder to a single double-sized transfer drum and from there to the second double-sized printing cylinder. With this rotary printing machine, smooth sheet travel is achieved with single-sided multi-color printing, but it is disadvantageous with face and reverse printing that, in the transfer area of the double-sized transfer drum, additionally controllable blow and suction boxes must be provided in order to lubricate the sheet on the drum, especially to prevent the bow end after the turning process.

Aufgabe der Erfindung ist es, eine Bogenoffsetrotationsdruckmaschine zu schaffen, bei welcher der im Schön- und Widerdruck über zwei Übertragungszylinder und die doppelt große Übertragungstrommel vorgesehener Bogenlauf für den einseitigen Mehrfarbendruck nur über die doppelt große Ubergabetrommel als einzige Trommel zwischen zwei doppelt großen Druckzylindern ermöglicht und zugleich das Zwischenmaß von Druckwerk zu Druckwerk für eine kompakte Reihenbauweise verringert. wird.The object of the invention is to provide a sheet-fed offset printing press in which the sheet travel provided in perfecting with two transfer cylinders and the double-size transfer drum for single-sided multi-color printing only allows via the double-size transfer drum as the only drum between two double-size printing cylinders and at the same time reduced the intermediate size from printing unit to printing unit for a compact series construction. becomes.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des ersten Patentanspruchs.This object is achieved by the characterizing features of the first claim.

Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie der Zeichnung und der Beschreibung.Further developments of the invention result from the subclaims and the drawing and the description.

Durch diese Maßnahmen ist es möglich, die Vorteile der Bogenwendung mittels Anordnung eines ersten Übertragungszylinders, einer doppelt großen Übertragungstrommel und eines Wendezylinders zwischen zwei Druckzylindern, d.h. dieVorteile einer Drei-Trommel-Wendung, insbesondere hinsichtlich des bekannten abschmierfreien Bogenlaufes und einer registerhaltigen Bogenwendung mittels durchgehend mechanischer Greiferübergaben, durch die zusätzliche Möglichkeit des Umschaltens der doppelt großen Übertragungstrommel mit den bekannten Vorteilen eines sanften, schlanken Bogenlaufes bei Anordnung nur einer einzigen doppelt großen Übertragungstrommel zwischen doppelt großen Druckzylindern, d.h. normalem Zwischentrommellauf, für einen einseitigen Mehrfarbendruck zu verbinden. Der einseitige Mehrfarbendruck in Bogenoffsetrotationsdruckmaschinen genannten Art unterliegt dann nicht mehr den nachteiligen Beschränkungen durch eine Drei-Trommel-Wendung, wie das bisher der Fall war, insbesondere hinsichtlich der Schwierigkeiten bei der Verarbeitung von Karton bei Arbeitsgeschwindigkeiten größer als 10.000 Bogen/h. Außerdem ermöglicht der erfindungsgemäß umschaltbare Bogenlauf eine Reihenbauweise mit Verkürzung des Zwischenmaßes von Druckwerk zu Druckwerk auf weniger als den Durchmesser der doppelt großen Übertragungstrommel 7, weil beim Schön- und Widerdruck die aufeinanderfolgenden drei Trommeln bzw. Übertragungszylinder gegenüber der üblichen Anordnung kompakter miteinander verbunden sind.These measures make it possible to take advantage of the sheet turning by arranging a first transfer cylinder, a double-size transfer drum and a turning cylinder between two printing cylinders, i.e. the advantages of a three-drum turn, especially with regard to the known lubrication-free sheet run and a register-correct sheet turning by means of continuous mechanical gripper transfers, through the additional possibility of switching the double-sized transfer drum with the known advantages of a smooth, slim sheet run when arranging only a single double-sized transfer drum between double-sized impression cylinders, ie normal intermediate drum barrel, for a one-sided multi-color printing. Single-sided multi-color printing in sheet-fed offset printing presses is then no longer subject to the disadvantageous restrictions of a three-drum turn, as was previously the case, in particular with regard to the difficulties in processing cardboard at working speeds greater than 10,000 sheets / h. In addition, the switchable sheet travel according to the invention enables a series construction with a shortening of the intermediate dimension from printing unit to printing unit to less than the diameter of the double-sized transfer drum 7, because in the perfecting, the successive three drums or transfer cylinders are more compactly connected to one another compared to the usual arrangement.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand einer Zeichnung erläutert.

  • Es zeigt: Fig. 1 eine Bogenoffsetrotationsdruckmaschine mit zwei Druckwerken in Reihenanordnung, schematisch, eingestellt für Schön- und Widerdruck.
  • Fig. 2 eine Bogenoffsetrotationsdruckmaschine mit zwei Druckwerken in Reihenanordnung, schematisch, eingestellt für einseitigen Mehrfarbendruck.
An embodiment of the invention is explained below with reference to a drawing.
  • 1 shows a sheet-fed offset printing press with two printing units arranged in a row, schematically, set for face and back printing.
  • Fig. 2 is a sheet-fed offset printing press with two printing units in a row arrangement, schematically, set for single-sided multi-color printing.

Das in Fig. 1 und 2 schematisch dargestellte Zweifarbendruckwerk besteht aus zwei Plattenzylindern 1, 2, zwei Gummizylindern 3, 4 und zwei doppelt großen Druckzylindern 5, 6, zwischen denen ein Übertragungszylinder 17, eine doppelt große Übertragungstrommel 7 und eine Wendetrommel 21 angeordnet sind. Die Bogenübergabe erfolgt generell durch mechanische Greiferübergaben. Hierzu sind am Druckzylinder 5 Greiferreihen 10, 11 am Übertragungszylinder 17 Greiferreihen 9, an der doppelt großen Übertragungstrommel 7 Greiferreihen 12, 13, an der Wendetrommel 21 in bekannter Weise nach innen schwenkbare, zusammenwirkende Greiferreihen 18, 19 sowie am Druckzylinder 6 Greiferreihen 22, 23 befestigt. Die Farbwerke an den Plattenzylindern 1, 2 sind nicht dargestellt. Die doppelt große Übertragungstrommel 7 ist in der Drehrichtung veränderbar und ebenso wie der Übertragungszylinder 17 in schwenkbaren Lagern 8 bzw. 16 angeordnet. Die Bewegung erfolgt entsprechend der in Fig. 1 und 2 eingezeichneten Pfeile in die Position 7' bzw. 17'. Die an der doppelt großen Übertragungstrommel 7 befestigten Greiferreihen 12, 13 weisen Zangengreifer auf. Durch diese Maßnahmen kann die doppelt große Übertragungstrommel 7 für einen zwischen Schön- und Widerdruck (Fig. 1) und einseitigem Mehrfarbendruck (Fig. 2) umschaltbaren Bogenlauf wahlweise in eine von zwei Stellungen gebracht und in der Drehrichtung verändert werden, derart, daß in der ersten Stellung bei abgestelltem Übertragungszylinder 17 Kontakt zu den beiden doppelt großen Druckzylindern 5, 6 für einen einseitigen Mehrfarbendruck besteht, während in der zweiten Stellung und Drehrichtung für den Schön- und Widerdruck die doppelt große Übertragungstrommel 7 nach unten an den Wendezylinder 21 und außerdem der beim einseitigen Mehrfarbendruck abgestellte Ubertragungszylinder 17 von oben an den ersten doppelt großen Druckzylinder 5 und an die doppelt große Übertragungstrommel 7 anstellbar ist.1 and 2 schematically shown two-color printing unit consists of two plate cylinders 1, 2, two blanket cylinders 3, 4 and two double-size printing cylinders 5, 6, between which a transfer cylinder 17, a double-size transfer drum 7 and a reversing drum 21 are arranged are not. The sheet transfer is generally carried out by mechanical gripper transfers. For this purpose, there are 5 gripper rows 10, 11 on the transfer cylinder 17 gripper rows 9, on the double-sized transfer drum 7 gripper rows 12, 13, on the turning drum 21 in a known manner, inwardly pivotable, interacting gripper rows 18, 19 and on the pressure cylinder 6 gripper rows 22, 23 attached. The inking units on the plate cylinders 1, 2 are not shown. The double-sized transfer drum 7 can be changed in the direction of rotation and, like the transfer cylinder 17, is arranged in pivotable bearings 8 and 16, respectively. The movement takes place according to the arrows drawn in FIGS. 1 and 2 into positions 7 'and 17', respectively. The gripper rows 12, 13 fastened to the double-sized transfer drum 7 have pliers grippers. Through these measures, the double-sized transfer drum 7 for a switchable between face and reverse printing (Fig. 1) and single-sided multi-color printing (Fig. 2) can be brought into one of two positions and changed in the direction of rotation, such that in the first position when the transfer cylinder 17 is turned off there is contact with the two double-sized printing cylinders 5, 6 for single-sided multi-color printing, while in the second position and direction of rotation for perfecting, the double-sized transfer drum 7 is facing down to the reversing cylinder 21 and also when one-sided multi-color printing transfer cylinder 17 can be adjusted from above to the first double-size printing cylinder 5 and to the double-size transfer drum 7.

Um eine einwandfreie Anlage des Bogens 20 mit seiner Hinterkante an der doppelt großen Übertragungstrommel 7 und einer registergenauen Übergabe zu erreichen, sind auf das Bogenende einstellbare (s. Pfeile, Fig. 1) Glätteinrichtungen 14, 15 vorgesehen. Es ist aber auch möglich, auf diese Glätteinrichtungen zu verzichten und zusätzlich Sauger am Umfang des Wendezylinders sowie Blas-oder Saugvorrichtungen zum Aufstreichen des Bogens auf die doppelt große Übertragungstrommel 7 in bekannter Weise vorzusehen, um die nachlaufende Bogenkante festzuhalten und einen abschmierfreien Bogenlauf zu sichern. Bogenlauf und -übergabe erfolgen beim einseitigen Mehrfarbendruck mit nur einer doppelt großen Übertragungstrommel 7 zwischen doppelt großen Druckzylindern 5, 6 bzw. auch beim Schön- und Widerdruck mit einem Übertragungszylinder 17, einer doppelt großen Übertragungstrommel 7 und der Wendetrommel 21 zwischen den doppelt großen Druckzylindern 5, 6 jeweils in bekannter Weise, so daß sich eine nähere Erläuterung erübrigt. Es ist lediglich erforderlich, die entsprechenden Umschaltungen vorzunehmen.In order to achieve a perfect contact of the sheet 20 with its rear edge on the double-sized transfer drum 7 and a register-accurate transfer, smoothing devices 14, 15 are provided on the sheet end (see arrows, FIG. 1). However, it is also possible to dispense with these smoothing devices and to additionally provide suction devices on the circumference of the turning cylinder and blowing or suction devices for spreading the sheet onto the double-sized transfer drum 7 in a known manner in order to hold the trailing sheet edge and to ensure a lubrication-free sheet run. Sheet travel and transfer take place in single-sided multi-color printing with only one double-sized transfer drum 7 between double-sized printing cylinders 5, 6 and also in perfecting with a transfer cylinder 17, a double-sized transfer drum 7 and the reversing drum 21 between the double-sized printing cylinders 5 , 6 each in a known manner, so that a further explanation is unnecessary. It is only necessary to make the appropriate switchovers.

Das Abschwenken von Übertragungstrommel 7 und Übertragungszylinder 17 ist nicht auf die genannten schwenkbaren Lager 8, 16 beschränkt, sondern es sind auch andere bekannte Vorrichtungen anwendbar, mittels denen die geometrische Lage und die Drehrichtung einer Antriebsachse zum Zwecke des Umschaltens des Bogenlaufes verändert werden kann.The pivoting of the transfer drum 7 and transfer cylinder 17 is not limited to the mentioned pivotable bearings 8, 16, but other known devices can be used, by means of which the geometric position and the direction of rotation of a drive axis can be changed for the purpose of switching the sheet travel.
