Abstract

The transfer drum has air outlets in the drum's cap(3) so as to form an air cushion between the cap and a sheet of paper to transported. The interior of the transfer drum is supplied with air at excess pressure by an air-supply system (15). The cap has flap (4) sealing off the drum's interior from outside, near the rear edge (11) of the drum-cap. The other end of the flap is joi to the transfer drum. The flap is movably positioned by means of rollers (6) in a guide (7).

Description

Die Erfindung betrifft eine Übergabetrommel mit schwenkbaren Trommelkappen zwischen Druckwerken oder nach Lackierwerken von Bogendruckmaschinen.The invention relates to a transfer drum with pivotable drum caps between Printing units or after coating units of sheet-fed printing machines.

Bogenübergabetrommeln von Druckmaschinen müssen so beschaffen sein, dass ein Abschmieren der bedruckten oder lackierten Flächen des Bogens am Trommelmantel vermieden wird. Da sich einerseits die zu transportierenden Bögen in Abhängigkeit von ihrer Biegesteifigkeit beim Transport unterschiedlich verhalten und andererseits je nach vorhergehenden Druckstufen unterschiedliche Bogenführungsmittel bevorzugt werden, wurden verschiedene Bogenführungsvarianten an Übergabetrommeln entwickelt die jeweils nur für bestimmte Materialsorten und Druckvarianten optimal geeignet sind.
Um das Abschmieren von Papierbögen an der Übergabetrommel zu verhindern, wird beispielsweise mit Hilfe von Blasluft, die durch Luftaustrittsöffnungen im Trommelmantel strömt, ein Luftpolster auf der Trommeloberfläche aufgebaut (DE 4 434 778).
Beim Transport von Kartonbögen ist diese Lösung jedoch mit intensivem Einsatz von Blasluft und damit hohen Betriebskosten verbunden und für dickere Kartonsorten nicht mehr geeignet.
Insbesondere für die abschmierfreie Führung biegesteifer Kartonbögen sind deshalb zur Schaffung der benötigten Freiräume für den Bogen anstelle eines zylindrischen Trommelmantels sekantenartig angeordnete Bogenleitbleche aus der EP 230 032 bekannt. Die darin beschriebene Übergabetrommel kann auf die Verarbeitung von Papier umgerüstet werden, indem zusätzliche Bogentragelemente in den Trommelmantel eingefügt werden. Nachteilig wirkt sich dabei aus, dass der Umrüstaufwand infolge manueller Montagearbeiten recht hoch ist und die für den Papiertransport modifizierte Trommel durch das Fehlen eines äußeren Luftpolsters nicht die für jeden Anwendungsfall ausreichende Sicherheit gegen Abschmieren bietet.Sheet transfer drums of printing presses must be designed in such a way that the printed or varnished surfaces of the sheet on the drum shell are not smeared. Since on the one hand the sheets to be transported behave differently depending on their bending stiffness during transport and on the other hand different sheet guiding means are preferred depending on the previous pressure levels, different sheet guiding variants on transfer drums were developed which are only optimally suited for certain types of material and printing variants.
In order to prevent sheets of paper from smearing on the transfer drum, an air cushion is built up on the drum surface, for example with the aid of blown air which flows through air outlet openings in the drum jacket (DE 4 434 778).
When transporting cardboard sheets, however, this solution involves intensive use of blown air and thus high operating costs and is no longer suitable for thicker cardboard types.
In particular for the lubrication-free guidance of rigid cardboard sheets, therefore, to create the required clearances for the sheet, instead of a cylindrical drum jacket, sheet guide plates arranged in secant fashion are known from EP 230 032. The transfer drum described therein can be converted to process paper by inserting additional sheet support elements into the drum jacket. The disadvantage here is that the conversion effort due to manual assembly work is quite high and the drum modified for paper transport does not offer sufficient protection against lubrication due to the lack of an external air cushion for every application.

In der DE 3 536 442 wird ein Bogenführungszylinder für ein breites Spektrum von Papiersorten beschrieben, auf dessen Umfang schwenkbare Kappensegmente angeordnet sind, aus denen Blasluft radial austritt und die durch zwischen den Segmenten befindliche Staubleche gegeneinander abgedichtet sind. Von Nachteil sind bei dieser Konstruktion der hohe konstruktive Aufwand, die zusätzlich notwendige manuelle Verstellung des abschließenden Staubleches über ein Schneckengetriebe und die vielen Einstellparameter für den Bediener. DE 3 536 442 describes a sheet guiding cylinder for a wide range of paper types described, on the circumference of which pivotable cap segments are arranged, from which blowing air emerges radially and through the baffles located between the segments are sealed against each other. The disadvantage of this construction is the high constructive effort, the additional necessary manual adjustment of the final Dust bites via a worm gear and the many setting parameters for the operator.

Aufgabe der Erfindung ist es deshalb, eine flexibel einsetzbare Übergabetrommel zu schaffen, die mit geringem Umstellaufwand eine für jede zu verarbeitende Materialstärke optimale abschmierfreie Führung von bedruckten oder lackierten Bögen gewährleistetThe object of the invention is therefore to create a flexible transfer drum, the one that is optimal for every material thickness to be processed with little changeover effort Lubrication-free guidance of printed or varnished sheets guaranteed

Diese Aufgabe wird durch die kennzeichnenden Merkmale des ersten Anspruches gelöst.This object is achieved by the characterizing features of the first claim.

Die beweglichen Klappen zwischen den Hinterkanten radial schwenkbarer Trommelkappen und dem Trommelkörper schließen den Trommelinnenraum nach außen ab und ermöglichen dadurch die Erzeugung eines Überdruckes im Trommelinneren durch ein geeignetes Luftversorgungssystem. Über Luftaustrittsöffnungen in den Trommelkappen entsteht dann das für die abschmierfreie Bogenführung von bedrucktem oder lackiertem Papier gewünschte äußere Luftpolster.
Für den Transport von Kartonbögen werden die Trommelkappen zusammen mit den erfindungsgemäßen Klappen nach innen eingeschwenkt. In den dadurch geschaffenen Freiräumen können sich biegesteife Bögen entspannen, ohne dass die bedruckte oder lackierte Fläche beschädigt wird.
Damit kann dieselbe Übergabetrommel bei nach außen geschwenkten Trommelkappen mit Luftpolster vorzugsweise für den Transfer von Papier und mit nach innen geschwenkten Trommelkappen ohne Luftpolster vorzugsweise für biegesteifen Karton eingesetzt werden.The movable flaps between the rear edges of the radially swiveling drum caps and the drum body close off the interior of the drum and thereby enable the generation of overpressure inside the drum by means of a suitable air supply system. The air cushion required for the smear-free sheet guidance of printed or coated paper is then created via air outlet openings in the drum caps.
For the transport of cardboard sheets, the drum caps are pivoted inwards together with the flaps according to the invention. Rigid arches can relax in the resulting free spaces without damaging the printed or painted surface.
This means that the same transfer drum can be used preferably for the transfer of paper when the drum caps with the air cushion are pivoted outwards, and preferably for rigid cardboard with the drum caps pivoted inwards without the air cushion.

Die erfindungsgemäße Übergabetrommel kann im Einzelnen wie in Fig. 1 dargestellt aussehen.
An einem drehbaren Trommelkörper 10 sind Seitenteile 1 befestigt, die jeweils auf ihrer Innenseite einen am Umfang verlaufenden Anschlag 2 für zwei schwenkbare Trommelkappen 3 aufweisen, der gleichzeitig die Abdichtung zwischen Trommelkappen 3 und Seitenteilen 1 übernimmt.
Die Trommelkappen 3 besitzen Luftaustrittsöffnungen und sind jeweils an ihren in Bogenlaufrichtung gesehen vorderen Kanten drehbar an diametral gegenüberliegenden Trommelkappengelenken 14 am Trommelkörper 10 gelagert und werden mit Hilfe zweier Pneumatikzylinder 8 entweder in eine ausgeschwenkte äußere Position 3a (Volllinien) oder eine eingeschwenkte innere Position 3b (Strichpunktlinien) bewegt. Die Pneumatikzylinder 8 sind dazu unterhalb der Greiferbrücken 9 am Trommelkörper 10 befestigt und greifen mit den Kolbenstangenköpfen in entsprechende Gelenke 16 auf den jeweiligen Trommelkappenunterseiten ein.
An den Hinterkanten 11 der Trommelkappen 3 befinden sich die erfindungsgemäßen Klappen 4. Sie sind über seitlich angebrachte Rollen 6 in Führungsbahnen 7 an den Trommelkappenunterseiten tangential verschiebbar gelagert und über ein Scharnierband 5 mit Blechen 12 verbunden, die im Bereich der Greiferbrücken 9 am Trommelkörper 10 angesetzt sind.
Für den Transport von Papierbögen werden die zwei Trommelkappen 3 in die äußere Position 3a ausgeschwenkt. Die Seitenteile 1 der Übergabetrommel, die schwenkbaren Trommelkappen 3, die Klappen 4 und die Bleche 12 bilden in dieser Position zwei nach außen geschlossene Trommelinnenräume, die durch geeignete Luftversorgungssysteme 15 mit Luftüberdruck beaufschlagt werden können. Diesen Zweck erfüllen z.B. in den Seitenteilen 1 eingebaute, in Fig. 1 nur angedeutete Ventilatoren. Durch die Seitenteile 1 wird Blasluft ins Trommelinnere geleitet und über Luftaustrittsöffnungen in den Trommelkappen 3 das äußere Luftpolster aufgebaut.
Zur Verringerung unerwünschter Druckverluste befinden sich an den nach innen abgewinkelten Kappenhinterkanten 11 Dichtungsprofile 13, an denen die Klappen 4 in ausgeschwenkter Position 4a anliegen.
Vorzugsweise für den Transport biegesteifer Kartonbögen werden die Trommelkappen 3 pneumatisch nach innen bis an die Bleche 12 geschwenkt (3b) und vergrößem dadurch den zur Entspannung des Bogens benötigten Freiraum zwischen Bogen und Trommelkappe 3. The transfer drum according to the invention can look in detail as shown in FIG. 1.
On a rotatable drum body 10, side parts 1 are fastened, each of which has on its inside a circumferential stop 2 for two pivotable drum caps 3, which at the same time takes over the sealing between drum caps 3 and side parts 1.
The drum caps 3 have air outlet openings and are each rotatably supported at their front edges, as seen in the direction of sheet travel, on diametrically opposite drum cap joints 14 on the drum body 10 and, with the aid of two pneumatic cylinders 8, are either in a pivoted-out outer position 3a (solid lines) or a pivoted-in inner position 3b (dash-dot lines) ) emotional. The pneumatic cylinders 8 are attached to the drum body 10 below the gripper bridges 9 and engage with the piston rod heads in corresponding joints 16 on the respective underside of the drum cap.
The flaps 4 according to the invention are located on the rear edges 11 of the drum caps 3. They are mounted tangentially displaceably on guide rollers 7 on the underside of the drum caps by means of laterally attached rollers 6 and are connected via a hinge band 5 to metal sheets 12 which are attached to the drum body 10 in the area of the gripper bridges 9 are.
For the transport of sheets of paper, the two drum caps 3 are swung out into the outer position 3a. In this position, the side parts 1 of the transfer drum, the pivotable drum caps 3, the flaps 4 and the sheets 12 form two drum interiors which are closed to the outside and which can be subjected to air pressure by suitable air supply systems 15. This purpose is fulfilled, for example, by fans built into the side parts 1 and only indicated in FIG. 1. Blown air is conducted into the inside of the drum through the side parts 1 and the outer air cushion is built up via air outlet openings in the drum caps 3.
To reduce undesirable pressure losses, there are sealing profiles 13 on the inwardly angled rear edges 11 of the cap, against which the flaps 4 rest in the pivoted-out position 4a.
Preferably for the transport of rigid cardboard sheets, the drum caps 3 are pivoted pneumatically inwards up to the metal sheets 12 (FIG. 3b) and thereby increase the space between the sheet and the drum cap 3 required to relax the sheet.

Dabei werden die beweglichen Klappen 4 am Scharnierband 5 zwangsläufig miteingeschwenkt und unter die jeweils korrespondierenden Trommelkappen 3 geschoben (4b). In dieser Trommelkappenposition bleiben die Ventilatoren 15 abgeschaltet.
Die Figuren 2 und 3 zeigen zwei Einsatzvarianten für die beschriebene Übergabetrommel18. Der Bogentransport zwischen jeweils zwei Druckwerken 17 oder auch zwischen Lack- und Trockenwerken innerhalb von bogenverarbeitenden Offsetdruckmaschinen in Reihenbauweise erfolgt durch eine oder drei Übergabetrommeln 18, wobei jeweils mindestens eine Übergabetrommel 18 erfindungsgemäß gestaltet ist The movable flaps 4 on the hinge strap 5 are inevitably swiveled in and pushed under the corresponding drum caps 3 (FIG. 4b). The fans 15 remain switched off in this drum cap position.
FIGS. 2 and 3 show two variants of use for the transfer drum 18 described. The sheet transport between two printing units 17 or between coating and drying units within sheet-processing offset printing presses in series is carried out by one or three transfer drums 18, at least one transfer drum 18 being designed according to the invention
