The sheet to be printed can be spread smoothly onto the first blanket cylinder (2) by the second feed drum (4). <IMAGE>

Description

Die Erfindung betrifft eine Bogen-Offsetdruckmaschine für Schön- und Widerdruck, bei der das Bedrucken des Druckbogens zwischen zwei gegeneinander arbeitenden Gummizylindern erfolgt und ein erster Gummizylinder mit Greifern versehen ist, denen die Bogen von einer Anlagevorrichtung zuführbar sind, wobei ein unkontrolliertes Aufbringen von Farbe auf die Bogen durch vor der Druckzone angeordnete Führungseinrichtungen verhindert wird.The invention relates to a sheet-fed offset printing machine for face and back printing, in which the printing of the printing sheet takes place between two mutually working blanket cylinders and a first blanket cylinder is provided with grippers, to which the sheets can be fed by a contact device, with an uncontrolled application of ink the sheet is prevented by guide devices arranged in front of the printing zone.

Eine Druckmaschine dieser Gattung ist beispielsweise durch die DE-PS 543 116 bekannt. Bei derartigen Druckmaschinen erfolgt das Bedrucken des Druckgutes auf Vorder- und Rückseite gleichzeitig. Dabei ist Sorge dafür zu tragen, daß das Bogenende, das ja nicht von Greifern etc. geführt ist, nicht schon vor der eigentlichen Druckzone mit einem der Gummizylinder in Kontakt kommt, denn das auf dem Gummizylinder abgebildete Druckbild würde dann auf dem Bogen abschmieren. Demzufolge kommt es bei derartigen Druckmaschinen darauf an, das Druckgut vor dem Bedrucken exakt zu führen.A printing press of this type is known for example from DE-PS 543 116. In such printing machines, the printing of the printed matter on the front and back takes place simultaneously. Care must be taken to ensure that the end of the sheet, which is not guided by grippers etc., does not come into contact with one of the blanket cylinders before the actual printing zone, because the printed image depicted on the blanket cylinder would then smear on the sheet. Accordingly, it is important in such printing machines to precisely guide the printed matter before printing.

In der DE-PS 341 855 wird eine Rollenrotations-Druckmaschine für Schön- und Widerdruck nach dem Gummi/Gummi-Prinzip beschrieben. Bei dieser Maschine wird das Druckgut von einem zusätzlichen Gegendruckzylinder zunächst auf den ersten Gummizylinder gedrückt und einseitig bedruckt. Anschließend gelangt das Druckgut in die Druckzone zwischen den beiden Gummizylindern, wobei der zweite Druck erfolgt. Vorder- und Rückseite sind dann bedruckt, wobei die untere Seite eigentlich zweimal bedruckt ist, nämlich einmal zwischen Gegendruck-und Gummizylinder undxzweitens zwischen den beiden Gummizylindern. Bei einer Rollenrotationsdruckmaschine liegt das Problem aber gänzlich anders als bei einer Bogen-Rotationsdruckmaschine. Da im Gegensatz zu Rollenmaschinen der Bogenanfang. geführt und das Bogenende freiflatternd ist, ist bezüglich der Bogenführung ein erheblicher Mehraufwand erforderlich.DE-PS 341 855 describes a web-fed rotary printing press for face and back printing based on the rubber / rubber principle. With this machine, the print material is first pressed onto the first rubber cylinder by an additional impression cylinder and printed on one side. The print material then arrives in the printing zone between the two rubber cylinders, the second printing taking place. The front and back are then printed, the lower side actually being printed twice, namely once between the counterpressure and blanket cylinders and x secondly between the two blanket cylinders. The problem with a web-fed rotary printing press is completely different from that with a sheet-fed rotary printing press. In contrast to web presses, the beginning of the sheet. performed and the end of the sheet is fluttering, a considerable amount of additional effort is required with regard to the sheet guidance.

Über die Möglichkeiten der Bogenführung bei Gummi/Gummidruckmaschinen sind in verschiedenen Patentschriften Lösungsmöglichkeiten aufgezeigt.Various patent specifications show possible solutions for the possibilities of sheet guiding in rubber / rubber printing machines.

Bei der Vorrichtung nach der DE-PS 960 994 sind Führungsmittel vorgesehen, welche den Bogen bis zur Kontaktzone zwischen den beiden Gummizylindern heranführen. Weiterhin sind Mittel vorgesehen, mit denen die Greifer unabhängig vom Gummizylinder an der Innenseite jeder Maschinenseitenwand gelagert sind. Diese Anordnung soll gewährleisten, daß der Bogen auf einer Bahn geführt wird, wo eine vorzeitige Berührung mit einem Gummizylinder verhindert wird.In the device according to DE-PS 960 994 guide means are provided which lead the sheet up to the contact zone between the two rubber cylinders. Means are also provided with which the grippers are mounted on the inside of each side wall of the machine independently of the rubber cylinder. This arrangement is intended to ensure that the sheet is guided on a path where premature contact with a rubber cylinder is prevented.

Derartige aus dem Stand der Technik bekannten Bogenführungen sind jedoch konstruktiv sehr aufwendig und auch kompliziert. Trotzdem sind sie nicht geeignet, das Problem zu lösen, einen Bogen ohne Abschmierenbeidseitig im Gummi/ Gummi-Prinzip zu bedrucken.Such sheet guides known from the prior art are structurally very complex and also complicated. Nevertheless, they are not suitable for solving the problem of printing a sheet on both sides in the gum / gum principle without greasing.

Die Aufgabe der Erfindung besteht deshalb darin, eine Schön-und Widerdruckmaschine der eingangs erwähnten Gattung bezüglich der Bogenführung so auszugestalten, daß ein vorzeitiger unkontrollierter Kontakt des Druckgutes mit einem der Gummizylinder mit Sicherheit verhindert wird.The object of the invention is therefore to design a perfecting machine of the type mentioned at the outset with regard to the sheet guide in such a way that premature uncontrolled contact of the printed matter with one of the rubber cylinders is prevented with certainty.

Gelöst wird diese Aufgabe durch das Kennzeichen des ersten Patentanspruchs.This problem is solved by the characteristic of the first claim.

In Abkehr von der bisher bekannten Methode, die Bogen so zu führen, daß sie erst in der Druckzone mit dem Gummizylinder in Kontakt kommen, wird nunmehr vorgeschlagen, den zu bedruckenden Bogen schon vor der Druckzone auf den Gummizylinder aufzuwalzen.In departure from the previously known method of guiding the sheets so that they only come into contact with the blanket cylinder in the printing zone, it is now proposed to roll the sheet to be printed onto the blanket cylinder before the printing zone.

Diese erfindungsgemäße Ausgestaltung hat gegenüber den bekannten Vorrichtungen entscheidende Vorteile. So ist z.B. die zusätzliche Bogenführung vor dem eigentlichen Druckbereich nicht erforderlich. Dadurch wird die Maschine weniger störanfällig und auch bedienungsfreundlicher, da mögliche Störquellen nicht mehr vorhanden sind.This configuration according to the invention has decisive advantages over the known devices. For example the additional sheet guidance in front of the actual printing area is not necessary. This makes the machine less susceptible to faults and more user-friendly, since possible sources of interference are no longer available.

Durch die Zwischenschaltung einer zweiten Zuführtrommel wird eine exakte ruhige Bogenzuführung erreicht, wodurch der zu bedruckende Bogen auf den Gummizylinder aufgelegt werden kann. Der eigentliche Druck kann dann ohne die Gefahr des Abschmierens zwischen den Gummizylindern erfolgen.By interposing a second feed drum, an exact, smooth sheet feed is achieved, whereby the sheet to be printed can be placed on the blanket cylinder. The actual pressure can then take place without the risk of lubrication between the rubber cylinders.

Nachfolgend ist die Erfindung an Hand einer Skizze näher erläutert.The invention is explained in more detail below with the aid of a sketch.

Es zeigt:

  • Fig. 1 eine Schön- und Widerdruckmaschine, bei der der Schön- und Widerdruck zwischen zwei Gummizylindern erfolgt,
  • Fig. 2 die Lagerung einer Zuführtrommel und
  • Fig. 3 die Greiferöffnungskurve für die Zuführtrommel.
It shows:
  • 1 is a perfecting machine, in which the perfecting takes place between two blanket cylinders,
  • Fig. 2 shows the storage of a feed drum and
  • Fig. 3 shows the gripper opening curve for the feed drum.

Wie es aus Fig. 1 zu ersehen ist, handelt es sich um eine Gummi-Gummidruckmaschine, der die Druckbogen 9 von einem Anlegerstapel 1 vereinzelt zugeführt werden. Dabei werden die einzelnen Druekbogen 9 von einem Vorgreifer 10 an eine erste Zuführtrommel 3 gegeben, die wiederum den Druckbogen 9 an eine zweite Zuführtrommel 4 übergibt. Von dieser zweiten Zuführtrommel 4 aus gelangt der Druckbogen 9 auf den ersten Gummizylinder 2. Dieser Gummizylinder ist mit einem Greifersystem ausgestattet, das die exakte Fixierung des Druckbogens 9 gewährleistet und arbeitet mit einem zweiten Gummizylinder 11 zusammen. In der Kontaktzone 12 beider Gummizylinder 2, 11 erfolgt dann der Druck, wobei jeder Gummizylinder Gegendruckzylinder des anderen Gummizylinders ist. Nach dem Durchlaufen der Kontaktstelle 12 der beiden Gummizylinder 2, 11 wird der Bogen vom ersten Gummizylinder 2 abgenommen und einem Auslegerstapel 13 zugeführt.As can be seen from FIG. 1, it is a rubber-rubber printing machine to which the printed sheets 9 are fed individually from a feeder stack 1. The individual printing sheets 9 are fed from a pre-gripper 10 to a first feed drum 3, which in turn transfers the printing sheet 9 to a second feed drum 4. From this second feed drum 4, the printing sheet 9 reaches the first rubber cylinder 2. This rubber cylinder is equipped with a gripper system, which ensures the exact fixing of the printing sheet 9, and works with a second rubber cylinder 11 together. The pressure then takes place in the contact zone 12 of both blanket cylinders 2, 11, each blanket cylinder being an impression cylinder of the other blanket cylinder. After passing through the contact point 12 of the two rubber cylinders 2, 11, the sheet is removed from the first rubber cylinder 2 and fed to a delivery stack 13.

Durch die Verwendung einer zweiten Zuführtrommel 4 zwischen der ersten Zuführtrommel 3 und dem ersten Gummizylinder 2 wird eine Bogenführung erreicht, die ein Abschmieren des Druckbogens verhindert. Dabei ist die zweite Zuführtrommel 4 so zum ersten Gummizylinder 2 angeordnet, daß der Druckbogen 9 lediglich unverrückbar auf den ersten Gummizylinder 2 "aufgestrichen" wird, d.h. es erfolgt zwischen zweiter Zuführtrommel 4 und erstem Gummizylinder 2 kein Druck. Das Druckwerk entspricht in seinem Aufbau einem herkömmlichen Offsetdruckwerk und stellt somit keine Besonderheit dar.By using a second feed drum 4 between the first feed drum 3 and the first blanket cylinder 2, sheet guiding is achieved which prevents the printed sheet from smearing. In this case, the second feed drum 4 is arranged in relation to the first rubber cylinder 2 in such a way that the printed sheet 9 is only "immovably" spread over the first rubber cylinder 2, i.e. there is no pressure between the second feed drum 4 and the first rubber cylinder 2. The structure of the printing unit corresponds to that of a conventional offset printing unit and is therefore not special.

Damit zwischen der zweiten Zuführtrommel 4 und dem ersten Gummizylinder 2 die Möglichkeit einer Einstellbarkeit gegeben ist, ist die zweite Zuführtrommel 4 über ein Exzenterlager 5 zum Gummizylinder 2 einstellbar. Die Einstellung der zweiten Zuführtrommel 4 zum ersten Gummizylinder 2 hängt von der zu bedruckenden Papierstärke ab und ist auch im Bereich bis zum dicksten bedruckbaren Karton variabel.So that the possibility of adjustability is given between the second feed drum 4 and the first rubber cylinder 2, the second feed drum 4 can be adjusted via an eccentric bearing 5 to the rubber cylinder 2. The setting of the second feed drum 4 to the first rubber cylinder 2 depends on the paper thickness to be printed and is also variable in the range up to the thickest printable cardboard.

Damit eine einwandfreie Bogenübergabe zwischen Zuführtrommel 4 und Gummizylinder 2 ermöglicht wird, ist die Greiferöffnungskurve 6 zentrisch zur zweiten Zuführtrommel 4 angeordnet. Dazu weist das Exzenterlager 5 im Bereich, in dem die Greiferöffnungskurve 6 angeordnet ist, einen zur Achse der Zuführtrommel 4 zentrisch gedrehten Bund 15 auf. Durch die Führungsbolzen 7 ist die Anlage am Seitenständer 8 gewährleistet. Durch einen im Seitenständer 8 angeordneten Exzenterbolzen 16, der in eine Ausnehmung 17 in dem Greiferöffnungskurventräger 18 eingreift, ist die Greiferöffnungskurve 6 auf einen minimalen Übergabefehler optimierbar. Diese Anordnung gestattet ein exaktes öffnen und Schließen der Greifer 14 zu den vorgegebenen Zeiten unabhängig von der Stellung der Zuführtrommel 4, d.h. es tritt bei der Übergabe ein extrem geringer Tangentialfehler auf.So that a perfect sheet transfer between the feed drum 4 and the blanket cylinder 2 is made possible, the gripper opening curve 6 is arranged centrally to the second feed drum 4. For this purpose, the eccentric bearing 5 has, in the region in which the gripper opening curve 6 is arranged, a collar 15 rotated centrally with respect to the axis of the feed drum 4. The guide bolts 7 ensure that they rest on the side stand 8. The gripper opening curve 6 can be optimized for a minimal transfer error by means of an eccentric pin 16 arranged in the side stand 8 and engaging in a recess 17 in the gripper opening cam carrier 18. This arrangement allows the grippers 14 to be opened and closed exactly at the predetermined times regardless of the position of the feed drum 4, ie an extremely small tangential error occurs during the transfer.
