In order to achieve a safe, register-correct sheet transfer from the storage drum (8) and a lubrication-free sheet transfer, fixedly positioned face-pressure grippers (14, 15) and counterpressure grippers (16, 17) adjustable to the sheet format and, viewed in the direction of rotation, provided behind the clamping grippers (18, 19) on the storage drum (8) on the sheet end adjustable smoothing devices (20, 21).

Description

Die Erfindung betrifft eine Bogenwendevorrichtung für Rotationsdruckmaschinen in Reihenbauweise nach dem Oberbegriff des 1. Patentanspruches. Eine Bogenwendevorrichtung genannter Art ist aus der DE-OS 2 633 183 bekannt. Mit dieser bekannten Bogenwendevorrichtung ist jedoch eine Registerhaltung des Bogens für das nachfolgende Bedrucken nicht möglich. Die Übertragung der Bogenkanten beim Schön- und Widerdruck erfordert eine Genauigkeit, die mit der dort vorgesehenen Mehrgelenk-Schwinggreifer-Obergabe (siehe Fig. 7 bis 9) nicht ermöglicht werdenkann. Es hat sich nämlich gezeigt, daß die nachlaufende Bogenkante während der Übertragung auf die Greifer nichtnur fest erfaßt, sondern der Bogen gestrafft auf den Mantel der Speichertrommel aufgelegt werden muß. Hierfür ist die dort verwendete Mehrgelenk-Schwinggreifer-Konzeption zwischen θbergabe- und Speichertrommel nicht geeignet. Weil der nachfolgende Bogen bereits ankommt, bevor der vorhergehende Bogen weggeführt ist, muß eine Steuerung auf verschiedenen Bahnen erfolgen (siehe Fig. 8). Außerdem besteht im Übergabebereich die Gefahr des Abschmierens des Bogens - an dem unter dem Bogenlauf angeordneten Mehrgelenk-Schwinggreifer.The invention relates to a sheet turning device for rotary printing presses in series construction according to the preamble of the first claim. A sheet turning device of the type mentioned is known from DE-OS 2 633 183. With this known sheet turning device, however, it is not possible to keep the sheet in register for the subsequent printing. The transfer of the sheet edges in the perfecting requires an accuracy which cannot be made possible with the multi-link vibrating gripper transfer provided there (see FIGS. 7 to 9). It has been shown that the trailing sheet edge is not only firmly gripped during the transfer to the gripper, but the sheet must be placed tightly on the jacket of the storage drum. The multi-link vibrating gripper design between the transfer and storage drum used there is not suitable for this. Because the following sheet arrives before the previous sheet is led away, control must take place on different tracks (see FIG. 8). In addition, there is a risk of the sheet smearing in the transfer area - on the multi-link vibrating gripper arranged under the sheet run.

Durch die DE-OS 2 625 750 ist es bekannt, die Druckzylinder aufeinander folgender Druckwerke durch einen einzigen Obertragungszylinder zu verbinden, und das Wenden generell mit zusammenwirkenden Klemmgreiferreihen ausschließlich auf dem Umfang des Obertragungszylinders zu erreichen.From DE-OS 2 625 750 it is known to connect the printing cylinders of successive printing units by means of a single transfer cylinder, and to achieve turning generally with interacting rows of clamping grippers only on the circumference of the transfer cylinder.

Von Nachteil ist, daß eine erhöhte Abschmiergefahr beim Abheben des Bogens während des Wendevorgangs besteht, weil der Bogen mit seiner frisch bedruckten Seite sich relativ unkontrolliert trotz Unterstützung mittels Blasluft bewegen kann. Dadurch kann nicht mit Sicherheit verhindert werden, daß die frisch bedruckte, zunächst innen liegende und dem Umfang des Obertragungszylinders berührende Bogenseite nach dem Abheben noch einmal mit dem Zylinderumfang in Berührung kommt. Außerdem weist diese Vorrichtung keine zusätzliche, als Bogenführung im Schöndruck geeignete Speichertrommel auf.The disadvantage is that there is an increased risk of smearing when lifting the sheet during the turning process, because the sheet with its freshly printed side can move relatively uncontrolled despite support by blowing air. This cannot be prevented with certainty be that the freshly printed, initially inside and touching the circumference of the transfer cylinder sheet side comes back into contact with the cylinder circumference after lifting. In addition, this device has no additional storage drum suitable for sheet guiding in straight printing.

Es ist auch bereits eine Bogenwendevorrichtung für Rotationsdruckmaschinen in Reihenbauart aus der DE-AS 2 305 132 bekannt, bei denen die Druckzylinder aufeinander folgender Druckwerke durch eine einzige Oberführtrommel verbunden sind und zum Wenden zwei Paar aus zwei zusammenwirkenden Klemmgreiferreihen bestehende Greifersysteme, die im halben Umfang versetzt zueinander an dem auf die überführtrommel in Transportrichtung folgenden Druckzylinder angeordnet sind, vorgesehen sind. Diese Bogenwendevorrichtung weist zwar durchgängig mechanische Greiferübergaben auf, der Nachteil ist aber, daß im Übergabebereich der Oberführtrommel Blas- oder Saugkästen vorgesehen werden müssen, um ein Abschmieren der Bogen auf der Trommel, insbesondere des Bogenendes nach dem Wendevorgang, zu verhindern. Eine maximale Wirkung für verschiedene Papierformatlängen ist nur erreichbar, wenn eine taktmäßige Steuerung der Saug- oder Blaskästen erfolgt. Eine derartige Steuerung ist nicht nur aufwendig, sondern mit ständig höherer Druckgeschwindigkeit auch funktionsunsicher. Außerdem weist diese Bogenwendevorrichtung keine zusätzliche, als Bogenführung im Schöndruck geeignete Speichertrommel auf.There is also already known a sheet turning device for rotary printing machines in series from DE-AS 2 305 132, in which the printing cylinders of successive printing units are connected by a single top guide drum and two pairs of gripper systems consisting of two interacting rows of gripper grips which are offset by half the circumference are arranged on the pressure cylinder following the transfer drum in the transport direction. This sheet turning device has mechanical gripper transfers throughout, but the disadvantage is that blowing or suction boxes must be provided in the transfer area of the top guide drum in order to prevent smearing of the sheets on the drum, in particular the sheet end after the turning process. A maximum effect for different paper format lengths can only be achieved if the suction or blow boxes are controlled in cycles. Such a control is not only complex, but also functionally unsafe with a constantly higher printing speed. In addition, this sheet turning device has no additional storage drum suitable as sheet guide in straight printing.

Aufgabe der Erfindung ist es, eine Bogenwendevorrichtung eingangs genannter Art derart weiterzubilden, daß nicht nur eine sichere, registerhaltige Bogenübernahme von der Speichertrommel gewährleistet, sondern zugleich in dem folgenden Obergabebereich die Abschmiergefahr völlig beseitig wird.The object of the invention is to develop a sheet turning device of the type mentioned in such a way that not only a safe, register-based sheet transfer from the Storage drum guaranteed, but at the same time the risk of lubrication is completely eliminated in the subsequent transfer area.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des ersten Patentanspruchs. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie der Zeichnung und der Beschreibung.This object is achieved by the characterizing features of the first claim. Further developments of the invention result from the subclaims and the drawing and the description.

Durch diese Maßnahmen ist es nicht nur möglich, lediglich mit einer Obergabetrommel und ohne Sauggreifer zwischen zwei Druckwerken auszukommen, sondern es wird auch eine einwandfreie Registerhaltigkeit bei allen zur Verarbeitung kommenden Druckträgern, Drucklängen und hohen Druckgeschwindigkeiten erreicht, ohne daß im Obergabebereich nach dem Wendevorgang eine Abschmiergefahr besteht. Durch die Verwendung doppelt großer Zylinder wird außerdem ein für die Verarbeitung von Karton bei höchsten Arbeitsgeschwindigkeiten erforderlicher sanfter und schlanker Bogenlauf erzielt.These measures not only make it possible to use only one transfer drum and no suction gripper between two printing units, but also ensure that all print media, print lengths and high printing speeds are kept in perfect register without the risk of greasing in the transfer area after the turning process consists. The use of double-sized cylinders also achieves a smooth and slender sheet run required for processing cardboard at the highest working speeds.

Ein Ausführungsbeispiel der Erfindung wird nachstehend an Hand einer Zeichnung erläutert.

  • Es zeigt: Fig. 1 eine Bogenoffsetrotationsdruckmaschine mit nur einer doppelt großen Obergabetrommel zwischen doppelt großen Druckzylindern und einer zusätzlichen doppelt großen Speichertrommel, schematisch, eingestellt für Schöndruck,
  • Fig. 2 eine Bogenoffsetrotationsdruckmaschine wie Figur 1, schematisch, eingestellt für Schön- und Widerdruck.
An embodiment of the invention is explained below with reference to a drawing.
  • 1 shows a sheet-fed offset rotary printing press with only one double-sized transfer drum between double-sized printing cylinders and an additional double-sized storage drum, schematically set for straight printing,
  • Fig. 2 is a sheet-fed offset printing machine like Figure 1, schematically, set for perfecting.

Das in Figur 1 und 2 schematisch dargestellte Zweifarbendruckwerk besteht aus zwei Plattenzylindern 1, 2, zwei Gummizylindern 3, 4 und zwei doppelt großen Druckzylindern 5, 6, diemit nur einer doppelt großen Obergabetrommel 7 verbunden sind. Eine Speichertrommel 8 ist der Obergabetrommel 7 zusätzlich zugeordnet. Die Farbwerke an den Plattenzylindern 1, 2 sind nicht gezeigt. Die zu bedruckenden Bogen 9 werden in bekannter Weise dem Druckzylinder 5 zugeführt und vom Druckzylinder 6 wieder abgenommen. Die Druckzylinder 5, 6 sind jeweils mit zwei Reihen von Klemmgreifern 10, 11 bzw. 12, 13 versehen, die einander in bekannter Weise gegeüber liegen und entsprechend gesteuert zum Transport des Bogens 9 dienen. Für den Schöndruck weist die Übergabetrommel 7 zwei Greiferreihen von Schöndruckgreifern 14, 15 auf. Die Schöndruckgreifer 14, 15 die im halben Umfang versetzt zueinander angeordnet sind, arbeiten mit den Klemmgreifern 10, 11 bzw. 12, 13 der Druckzylinder 5, 6 zusammen und die Speichertrommel 8 wirkt im Schöndruck infolge ausgeschalteter Greiferübergaben zugleich als zusätzliche Bogenführungstrommel. Um ein Wenden des Bogens 9 zu ermöglichen, weist die Übergabetrommel 7 außerdem auf das Bogenende (siehe Pfeile) einstellbare Widerdruckgreifer 16, 17 auf. Im Schöndruck sind die Widerdruckgreifer 16, 17 in das Zylinderinnere der Obergabetrommel 7 außer Funktion eingeschwenkt (Fig. 1).The two-color printing unit shown schematically in FIGS. 1 and 2 consists of two plate cylinders 1, 2, two blanket cylinders 3, 4 and two double-size printing cylinders 5, 6, which are connected to only one double-size transfer drum 7. A storage drum 8 is additionally assigned to the transfer drum 7. The inking units on the plate cylinders 1, 2 are not shown. The sheets 9 to be printed are fed to the printing cylinder 5 in a known manner and removed from the printing cylinder 6 again. The pressure cylinders 5, 6 are each provided with two rows of clamping grippers 10, 11 and 12, 13, which face each other in a known manner and are used for the transport of the sheet 9 in a controlled manner. For the straight printing, the transfer drum 7 has two gripper rows of straight printing grippers 14, 15. The straight printing grippers 14, 15, which are arranged offset to one another by half the circumference, work with the clamping grippers 10, 11 and 12, 13 of the printing cylinders 5, 6 and the storage drum 8 also acts as an additional sheet guide drum in straight printing as a result of the gripper transfers being switched off. In order to enable the sheet 9 to be turned, the transfer drum 7 also has counterpressure grippers 16, 17 which can be adjusted to the sheet end (see arrows). In straight printing, the counterpressure grippers 16, 17 are pivoted into the cylinder interior of the transfer drum 7 out of function (FIG. 1).

Beim Schön- und Widerdruck arbeiten die Schöndruckgreifer 14, 15 mit Klemmgreifern 18, 19 der Speichertrommel 8 zusammen. Dabei treten die Widerdruckgreifer 16, 17 erst in Funktion, wenn der Bogen 9 vollständig auf der Speichertrommel 8 am betreffenden Mantelabschnitt anliegt. Um eine einwandfreie Anlage des Bogens 9 mit seiner Hinterkante an der Speichertrommel 8 und eine registergenaue übernahme durch die Widerdruckgreifer 16, 17 zu erreichen, sind auf das Bogenende einstellbare (siehe Pfeile) Glätteinrichtungen 20, 21 an der Speichertrommel 8 vorgesehen. Sobald der Bogen 9 geglättet auf der Speichertrommel 8 aufliegt, wird seine Hinterkante von den Widerdruckgreifern 16, 17 sicher erfaßt. Erst dann wird die Bogenvorderkante von den sich öffnenden Klemmgreifern 18, 19 der Speichertrommel 8 freigegeben. Die letzte Phase der Bogenwendung ist in Figur 2 gestrichelt dargestellt. Die ursprüngliche Bogenhinterkante wird zur Bogenvorderkante und der Bogen 9 wird ohne Abschmiergefahr an die Klemmgreifer 12, 13 des zweiten Druckzylinders 6 übergeben.In the case of perfecting, the straight-sided printing grippers 14, 15 work together with clamping grippers 18, 19 of the storage drum 8. The counterpressure grippers 16, 17 only come into operation when the sheet 9 lies completely on the storage drum 8 on the relevant jacket section. In order for the sheet 9 to rest properly with its trailing edge on the storage drum 8 and for register-accurate takeover by the counterpressure grippers 16, 17 reach, adjustable on the bow end (see arrows) smoothing devices 20, 21 are provided on the storage drum 8. As soon as the sheet 9 lies smoothly on the storage drum 8, its trailing edge is reliably gripped by the counterpressure grippers 16, 17. Only then is the leading edge of the sheet released by the opening grippers 18, 19 of the storage drum 8. The last phase of the turn is shown in dashed lines in Figure 2. The original trailing edge of the sheet becomes the leading edge of the sheet and the sheet 9 is transferred to the clamping grippers 12, 13 of the second printing cylinder 6 without risk of smearing.

Die Umstellung auf Schön- und Widerdruck erfolgt derart, daß die Glätteinrichtungen 20, 21 der Speichertrommel 8 jeweils auf das Bogenende eingestellt werden und das Druckwerk des zweiten Druckzylinders 6 so verdreht wird, daß der gewendete Bogen 9 von den auf das Bogenformat eingestellten Widerdruckgreifern 16, 17 an die Klemmgreifer 12, 13 des Druckzylinders 6 übergeben wird.The changeover to perfecting takes place in such a way that the smoothing devices 20, 21 of the storage drum 8 are each set to the end of the sheet and the printing unit of the second printing cylinder 6 is rotated such that the sheet 9 turned by the counterpressure grippers 16 set to the sheet format 17 is passed to the clamping grippers 12, 13 of the pressure cylinder 6.

Die Widerdruckgreifer 16, 17 können als bekannte Zangengreifer oder auch als bekannte Wendegreifer ausgebildet sein.The counter pressure grippers 16, 17 can be designed as known pliers grippers or also as known turning grippers.

Um zu verhindern, daß die fest positionierten Schöndruckgreifer 14, 15 im Bereich des zweiten Druckzylinders dessen geschlossene Oberfläche tangieren, ist eine bekannte Steuereinrichtung vorgesehen, um die Schöndruckgreifer 14, 15 unter die Drucklinie zeitgerecht abzusenken.In order to prevent the fixedly positioned fine-pressure grippers 14, 15 from touching its closed surface in the region of the second printing cylinder, a known control device is provided in order to lower the straight-pressure grippers 14, 15 below the pressure line in good time.

Die Erfindung ist nicht auf das beschriebene Beispiel beschränkt, sondern kann auch bei einer doppelt großen Obergabetrommel 7 zwischen einfach großen Druckzylindern verwendet werden. Ebenso kann die Speichertrommel 8 auch einfach groß ausgeführt sein.The invention is not restricted to the example described, but can also be used for a double-sized upper Gabetrommel 7 can be used between simply large printing cylinders. Likewise, the storage drum 8 can also be simply large.
