Abstract
Description
Die Erfindung betrifft eine Umführtrommel für Bogendruckmaschinen
gemäß dem Oberbegriff von Anspruch 1.The invention relates to a transfer drum for sheet-fed printing machines
according to the preamble of
Bei Bogendruckmaschinen werden die zu bedruckenden Bogen mittels Umführtrommeln zwischen den Druckwerken transportiert. Um ein Abschmieren der Bogen an der bedruckten Seite zu verhindern, sind eine Vielzahl von Bauformen derartiger Umführtrommeln bekannt geworden. Die Umführtrommeln können beispielsweise als Zylinder aufgebaut sein, wobei hier jedoch der Bogen mit der bedruckten Seite flächig in Kontakt mit der Zylinderoberfläche kommt.In sheet printing machines, the sheets to be printed transported between the printing units by means of transfer drums. To smear the sheets on the printed side To prevent a variety of designs are such Transfer drums became known. The transfer drums can for example, be constructed as a cylinder, but here the sheet with the printed side flat in contact with the Cylinder surface comes.
Weitere typische Bauformen für Umführtrommeln sind die als Transferter bezeichneten Umführtrommeln der Druckmaschinen R700, R900 der MAN Roland Druckmaschinen AG. Diese Umführtrommeln sind im wesentlichen als Kasten aufgebaut, wobei die den Bogen zugewandten Außenseiten des Kastens entweder eben bzw. konkav und/oder konvex gewölbt ausgebildet sind. Diese Außenflächen der Transferter können geschlossen oder mittels Durchbrüchen luftdurchlässig gestaltet sein.Other typical designs for transfer drums are the as Transferter designated transfer drums of the printing press R700, R900 from MAN Roland Druckmaschinen AG. These bypass drums are essentially constructed as a box, the the outside of the box facing the bow either flat or are concave and / or convex. This External surfaces of the Transferter can be closed or by means of Breakthroughs are designed to be permeable to air.
Diesen Transfertern sind zusätzlich mit Blas- und/oder Saugluft beaufschlagbare Bogenleitbahnen im unteren Bereich zugeordnet, wodurch zusätzlich die Gefahr des Abschmierens der bedruckten Seite des Bogens minimiert wird. Dies gilt sowohl für sehr dünne als auch für dicke Bedruckstoffe (Karton, Kunststofffolien).These transferters are also equipped with blowing and / or suction air Actuable arch guideways in the lower area assigned, which also increases the risk of greasing the printed side of the sheet is minimized. this applies for both very thin and thick substrates (cardboard, Plastic films).
Mögliche Bauformen der beschriebenen Transferter sind aus der DE 44 31 114 A1 bekannt. Die in dieser Schrift gezeigten Transferter weisen wenigstens zwei Greiferbrücken auf, die gleichmäßig am Umfang der Umführtrommel verteilt angeordnet sind. Die Außenflächen dieser prismatisch aufgebauten Transferter sind durch Ebenen gebildet, die zu den transportierten Bogen gewandten Außenseiten können jedoch auch konkav und/oder konvex gewölbt ausgebildet sein.Possible designs of the Transferter described are from the DE 44 31 114 A1 known. The ones shown in this document Transferters have at least two gripper bridges, the evenly distributed around the circumference of the transfer drum are. The outer surfaces of these prismatic transferters are formed by levels that are transported to the Arched outer sides can also be concave and / or be convex.
Bei sehr biegesteifen Bedruckstoffen (Schwerkarton, Wellpappe) besteht jedoch die Gefahr, dass gerade das Ende des Bogens nach dem Passieren des letzten Druckspaltes sowie nach Übergabe an den nächsten Gegendruckzylinder an der Außenfläche des Transferters (der Umführtrommel) anschlägt und es so zum Abschmieren kommt.For very rigid substrates (heavy cardboard, corrugated cardboard) however, there is a risk that the very end of the After passing the last pressure nip as well as after Transfer to the next impression cylinder on the outer surface of the transferter (the transfer drum) and so comes to smear.
Aus diesen Grunde ist es bekannt, die zuvorstehend beschriebenen Umführtrommeln mittels als Kappen bzw. Bügeln ausgebildeten Bogenführungen zu versehen. Diese Trommelkappen bzw. Bügel sind aus farbabstossendem Material gefertigt, so dass sich der Bogen insbesondere mit nicht druckenden Stellen abstützten kann. Ein sinnvoller Einsatz derartiger Einrichtungen ist jedoch nur dann möglich, wenn der Druckbogen entsprechende farbfreie Stellen im Sujet aufweist. Gerade schwere und biegesteife Bedruckstoffe, wenn auch weitestgehend vollflächig bedruckt, erschweren jedoch die Verwendung derartiger Einrichtungen bzw. machen den Einsatz derartiger Einrichtungen gar unmöglich. Beim Einsatz von Bedruckstoffen mit hohem Flächengewicht kann es ferner auch zur Beschädigung der Oberfläche im nicht bedruckten Bereich kommen. Auch dadurch wird Makulatur verursacht.For this reason, it is known to those described above Transfer drums by means of caps or brackets To provide bow guides. These drum caps or Temples are made of color-repellent material, so that the sheet in particular with non-printing areas can support. A sensible use of such facilities is only possible if the printed sheet has corresponding color-free spots in the subject. Just heavy and rigid substrates, albeit largely printed over the entire surface, however, make use more difficult such facilities or make the use of such Facilities impossible. When using substrates with a high basis weight it can also cause damage the surface in the unprinted area. Also this causes waste.
Die DE 41 11 262 C1 beschreibt eine Bogenführung an Bogenführungstrommeln von Bogendruckmaschinen, bei welcher der zu transportierende Bogen durch zwei den Kanten des Bogens zugeordnete und diesen an konischen Stützflächen tragende Stützscheiben gehalten wird. Die als Kegelradsegmente ausgebildeten Stützscheiben sind entsprechend dem Bogenformat auf der Achse der Trommel einstellbar montiert. Diese vorbekannte Bogenführungstrommel weist lediglich eine Greiferbrücke auf, d.h. die Trommel dreht eintourig.DE 41 11 262 C1 describes a sheet guide on sheet guide drums of sheet-fed printing machines, in which the to transporting arch through two the edges of the arch assigned and bearing these on conical support surfaces Support discs is held. The trained as bevel gear segments Support washers are based on the arch format the axis of the drum mounted adjustable. This previously known Sheet guide drum only has a gripper bridge, i.e. the drum turns one-speed.
Aus der DE-PS 725 705 ist eine Umführtrommel innerhalb einer Blechdruckmaschine bekannt, wobei die Umführtrommel zwei Greiferbrücken aufweist. Diese vorbekannte Umführtrommel besteht im wesentlichen aus einer Welle, an der die Greiferbrücken mittels radial verlaufenden Tragarmen befestigt ist. Unterhalb der Greiferbrücke und innerhalb der die Greiferbrücke tragenden Tragarme sind entsprechend dem Format der Blechtafeln verstellbar Stützscheiben mit konischen Tragflächen angeordnet.From DE-PS 725 705 is a transfer drum within one Sheet metal printing machine known, the transfer drum two Has gripper bridges. This known transfer drum consists essentially of a shaft on which the gripper bridges is attached by means of radially extending support arms. Below the gripper bridge and within the gripper bridge supporting arms are according to the format of the Sheet metal adjustable support discs with conical wings arranged.
Auch im Falle der letztgenannten Schrift sind die auf den Kantenbereich des Bogens einwirkenden Stützkörper als Scheiben ausgebildet, so dass eine derartige Bogenführungseinrichtung bei einer wie in der DE 44 31 114 A1 beschriebenen Umführtrommel mit zwei oder mehreren Greiferbrücken nicht verwendbar ist. Um gerade bei schnelldrehenden Bogendruckmaschinen eine passgerechte Bogenübergabe zu erzielen, müssen die Umführtrommeln eine ausreichend große Stabilität aufweisen, so dass entsprechend groß gestaltete und derartige Scheiben aufnehmende Durchbrüche durch den Trommelkörper nicht möglich sind.Even in the case of the last-mentioned font, these are based on Edge area of the arch acting support body as disks formed so that such a sheet guiding device in one as described in DE 44 31 114 A1 Transfer drum with two or more gripper bars is not is usable. Especially for fast-moving sheet-fed printing machines to achieve a suitable sheet transfer the transfer drums are sufficiently stable, so appropriately sized and such Disc-receiving openings through the drum body are not possible.

für Bogendruckmaschinen gemäß dem Oberbegriff von
Anspruch 1 derartig zu erweitern, so dass eine sichere und
vom Sujet unabhängige abschmierfreie Führung gerade von
schweren und biegesteifen Bedruckstoffen möglich ist.The object of the present invention is therefore a transfer drum
