Abstract
Description
Die Erfindung betrifft eine Bogenoffsetdruckmaschine mit einer Stanzvorrichtung zum Inline-Stanzen von bedruckten Bogen.The The invention relates to a sheet-fed offset printing machine with a punching device For inline punching of printed sheets.
Inline-Stanzen gehört zu den modernen Technologien der Bedruckstoffveredelung, die Arbeitsgänge der Weiterverarbeitung in den Maschinendurchlauf des Druckprozesses vorziehen und so zu großen Kosteneffekten führen.Inline punching belongs to the modern technologies of printing material processing, the operations of Further processing in the machine cycle of the printing process prefer and so big Cost effects lead.
Es ist bekannt, ein konventionelles Farb- oder Lackwerk bei Bedarf in eine Stanzeinrichtung umzurüsten. Dazu wird ein Stanzblech mit den zu realisierenden Konturen auf einem Druckzylinder eines Druckwerkes vorgesehen, das gegen den Gummituchzylinder arbeitet. Es ist auch möglich, das Stanzblech auf dem Gummituchzylinder anzuordnen und gegen einen Druckzylinder zu arbeiten.It is known, a conventional paint or coating unit when needed to convert into a punching device. For this purpose, a stamped sheet with the contours to be realized on a printing cylinder of a printing unit provided against the Blanket cylinder works. It is also possible to stamp the sheet on the To arrange blanket cylinder and to work against a printing cylinder.
Weiterhin ist bekannt, das Stanzgut nicht vollständig auszustanzen. Über dünne Stege bleibt es mit dem Rest des Bogens verbunden, so dass ein schadensfreier Weitertransport zur Auslage und ein späteres Ausbrechen erfolgen kann. Dabei ergibt sich das Problem, dass die Stege häufig nicht sauber reißen und sichtbare Reste am Druckprodukt stehen bleiben.Farther it is known not to punch out the punched goods completely. About thin bridges it stays connected to the rest of the bow, leaving a harmless one Further transport to the delivery and a later breakaway can take place. This results in the problem that the webs often do not tear clean and visible residues remain on the printed product.

Nachteilig an diesen genannten Lösungen ist, dass zum Zeitpunkt der Absaugung die Stanzgute sich meistens noch nicht vom Bogen gelöst haben. Sie sind noch in ihrer Ursprungsposition in die Bogenfläche integriert und in ihrer Schnittkante verfangen. Es ist deshalb ein hoher Unterdruck notwendig, um die Stanzgute sicher zu lösen. Der hohe Unterdruck wirkt sich andererseits nachteilig auf den Bogenlauf aus. Der Bogen wird dadurch spätestens beim Verlassen der Stanzzone mit der bedruckten Oberseite gegen die Saugeinrichtung gesaugt und es kommt zum Abschmieren. Abhilfe könnte ein breiter unbedruckter Rand an der Bogenhinterkante schaffen. Dies ist aber aus wirtschaftlichen Gründen heraus nicht vertretbar.adversely at these mentioned solutions, that at the time of extraction the stamped good mostly still not released from the bow to have. They are still integrated in their original position in the arch surface and caught in its cutting edge. It is therefore a high negative pressure necessary to safely release the punching goods. The high negative pressure works On the other hand disadvantageous to the sheet run. The bow will thereby at the latest at Leaving the punching zone with the printed top against the suction device sucked and it comes to greasing. Remedy could be a broad unprinted Create edge on the sheet trailing edge. But this is economic establish out unreasonable.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Bogenoffsetdruckmaschine mit einer Stanzvorrichtung zu schaffen, die ein Abschmieren des bedruckten Bogens beim Absaugen der Stanzgute sicher vermeidet.Of the The invention is therefore based on the object, a sheetfed offset printing press to provide with a punching device, which is a greasing of the printed bow safely avoided when sucking the punching good.
Erfindungsgemäß wird die Aufgabe durch eine Vorrichtung mit den Merkmalen des 1. Anspruchs gelöst. Vorteilhafte Ausgestaltungen und zweckmäßige Weiterbildungen sind in den jeweiligen Unteransprüchen beschrieben.According to the invention Task by a device having the features of the first claim solved. Advantageous embodiments and expedient developments are in the respective subclaims described.
Durch die erfindungsgemäße Anordnung der Stanzvorrichtung wird eine Umkehr der Saugrichtung bezogen auf die Bogenoberfläche bewirkt, so dass nur noch an der unbedruckten Unterseite abgesaugt wird. Dies hat den Vorteil, dass der für das Absaugen notwendige hohe Unterdruck nicht zum Abschmieren des Bogens führt.By the inventive arrangement the punching device is based on a reversal of the suction direction the arch surface causes so that only sucked on the unprinted bottom. This has the advantage that for the suction necessary high vacuum not to lubricate the Bow leads.
Ein durch die Absaugung bedingtes Abheben des hinteren Randes des bedruckten Bogens wird vermieden.One due to the suction conditional lifting of the back edge of the printed Bow is avoided.
Durch die muldenförmige Gestaltung des Absaugstutzens der Absaugeinrichtung auf der zur Bewegungsbahn des bedruckten und gestanzten Bogens weisenden Seite wird der Bogen durch den wirkenden Unterdruck in die Mulde eingesaugt und damit verformt.Due to the trough-shaped design of the suction of the suction on the for Movement of the printed and punched sheet facing side of the sheet is sucked by the negative pressure acting in the trough and thus deformed.
Durch die Verformung platzen die Stanzgute aus ihrer umlaufenden Schnittkante heraus und können durch den Saugstrom der Saugdüsen leichter erfasst werden. Stützelemente in der Saugdüse sollen das Einsaugen biegeschlaffer Bedruckstoffe verhindern. Mit der axialen Verschiebbarkeit der Stützelemente kann verhindert werden, dass ein Stützelement genau in Flucht mit einem Stanzgut im Bogen steht und so das Absaugen behindert.By the deformation burst the punching good from its circumferential cutting edge out and can by the suction flow of the suction nozzles be detected more easily. support elements in the suction nozzle should prevent the suction of non-sagging substrates. With the axial displacement of the support elements can be prevented be that a support element exactly in alignment with a stamped item is in the bow and so the suction with special needs.
Um sicherzustellen, dass alle Stanzgute abgesaugt werden, ist es vorteilhaft, mehrere Absaugeinrichtungen in das Bogenleitblech zu integrieren. Bevorzugt ist die Anordnung der Absaugeinrichtung an der tiefsten Stelle der Bogenleiteinrichtung und/oder in Bogenlaufrichtung am Anfang der Bogenleiteinrichtung.Around ensure that all the stamped goods are sucked off, it is advantageous integrate several suction in the sheet baffle. Prefers is the arrangement of the suction at the lowest point of the Sheet guiding device and / or in the sheet running direction at the beginning of Sheet guiding device.
Die Gestaltung der Absaugdüse der Absaugeinrichtung über die gesamte Breite des Bogens hat den Vorteil, dass bei Veränderung der Größe, Anzahl oder Lage der Stanzgute keine Umrüstarbeiten erforderlich sind.The Design of the suction nozzle the suction over The entire width of the bow has the advantage that when changing the size, number or Position of the punching good no retooling required are.
Durch die Abdeckung der Absaugöffnung zwischen axial benachbarten Stanzguten z.B. mittels Blechen, kann die zur Absaugung benötigte Luftmenge verringert werden.By the cover of the suction between axially adjacent punchings, e.g. by means of sheets, can the Suction needed Air quantity can be reduced.
Um ein vorzeitiges Lösen des Stanzgutes aus der umlaufenden Schnittkante sicher zu vermeiden, ist es denkbar, nach der Stanzeinrichtung eine Gebläsevorrichtung vorzusehen. Mit Hilfe von Blasdüsen wird der gestanzte Bogen an die Zylinderoberfläche gedrückt. Denkbar ist aber auch, die Zylinderoberfläche als Saugeinrichtung auszugestalten, durch die der Bogen gegen die Zylinderoberfläche gezogen wird.Around a premature release to avoid the stamped material from the peripheral cutting edge, It is conceivable, after the punching device, a blower device provided. With the help of tuyeres The punched sheet is pressed against the cylinder surface. It is also conceivable the cylinder surface to design as a suction device through which the bow against the Cylinder surface pulled becomes.
