Abstract

Sheet pressing means for a multi-color sheet-fed press adapted for both first-side printing and perfecting printing wherein the press includes a press frame and first and second impression cylinders with a sheet-turning cylinder therebetween. The sheet pressing means includes a plurality of hollow air-blowing fingers disposed after the printing zone of the first impression cylinder for directing blown air to press a sheet onto the surface of the first impression cylinder, with the fingers being disposed in substantially equidistant relationship to one another on a support tube which is disposed above the first impression cylinder and substantially parallel to the axis thereof along substantially the entire length of the first impression cylinder. Preferably, the fingers each have at the downstream end thereof an air exit surface with air exit orifices formed therein, and the exit surfaces are formed to conform generally to the convex external contour of the first impression cylinder and have a downstream tip end adapted to be positioned closely adjacent the point of tangency between the first impression cylinder and the sheet-turning cylinder. In the preferred embodiment, an articulated linkage is mounted on the press frame for selectively moving the support tube, the fingers and the tip ends thereof toward said point of tangency for perfecting printing and away from said point of tangency for first-side printing and a valve is provided for controlling the air flow through the fingers.

Description

Aus der Praxis ist es bereits bekannt, eine oder mehrere achsparallele Blasleisten vor oder nach der Druckzone ober­halb eines Druckzylinders so zu verteilen, daß der Bogen auf die Oberfläche des Druckzylinders abgesehen von der Blasluft, praktisch berührungslos glatt aufgestrichen wird.From practice it is already known to distribute one or more axially parallel blow strips before or after the printing zone above a printing cylinder so that the sheet is spread onto the surface of the printing cylinder apart from the blowing air, practically without contact.

Diese Blasvorrichtungen arbeiten im Schöndruck befriedigend. Sie sind aber ungeeignet, um auch das passerhaltige Abnehmen eines gewendeten Bogens vom vorgeordneten Druckzylinder mittels am Bogenwendezylinder angeordneter Sauger, Greifer oder dgl. zu verbessern bzw. auch ungeeignet die knitterfreie Übergabe ins nachfolgende Druckwerk des bereits gewendeten Bogens zu ermöglichen.These blowing devices work satisfactorily in straight printing. However, they are unsuitable for improving the register-containing removal of a turned sheet from the upstream printing cylinder by means of suction cups, grippers or the like arranged on the sheet turning cylinder, or also unsuitable for enabling the wrinkle-free transfer to the subsequent printing unit of the sheet already turned.

Es ist auch bereits aus mehreren Veröffentlichungen bekannt, den Bogen im Tangentenpunkt durch mechanische Mittel, z.B. am Umfang des Bogenwendezylinders befindliche Leitsegmente (s. DE-AS 2 040 712) oder aufblasbare Luftschläuche (s. JP-PA 58-145450) gegen die Oberfläche des dem Bogenwendezylinder vorgeordneten Druckzylinders zu pressen. Dadurch soll eine passerhaltige Abnahme des Bogens vom Druckzylinder an seiner Hinterkante und zugleich eine knitterfreie Übergabe des gewendeten Bogens im folgenden Druckwerk ermöglicht werden.It is also known from several publications that the arc at the tangent point by mechanical means, e.g. to press guiding segments (see DE-AS 2 040 712) or inflatable air hoses (see JP-PA 58-145450) on the circumference of the sheet-turning cylinder against the surface of the pressure cylinder arranged upstream of the sheet-turning cylinder. This is intended to enable the sheet to be removed from the printing cylinder at its trailing edge, and at the same time to ensure that the sheet that has been turned is not creased in the following printing unit.

Bei diesen Vorrichtungen ist von Nachteil, daß die mechanischen Mittel, falls keine druckfreien Korridore vorhanden sind, stets das Druckbild verwischen bzw. beein­trächtigen.A disadvantage of these devices is that the mechanical means, if there are no pressure-free corridors, always blur or impair the printed image.

Es ist deshalb Aufgabe der Erfindung, eine Vorrichtung in Mehrfarbenbogenrotationsdruckmaschinen für Schöndruck und Schön- und Widerdruck zu schaffen, mit der das Anpressen des bedruckten Bogens im Bereich vor dem Tangentenpunkt zwischen einem Bogenwendezylinder und dem vorgeordneten Druckzylinder an die geschlossene Oberfläche des Druckzylinders bis zum Erfassen des Bogenendes durch an dem Bogenwendezylinder angeordnete Sauger, Greifer o. dgl. berührungslos durch die Kraftwirkung strömender Luft ermöglicht wird.It is therefore an object of the invention to provide a device in multi-color sheet-fed rotary printing machines for straight printing and To create perfecting, with which the pressing of the printed sheet in the area in front of the tangent point between a sheet turning cylinder and the upstream printing cylinder to the closed surface of the printing cylinder until the sheet end is gripped by suction pads, grippers or the like arranged on the sheet turning cylinder is made possible by the force of flowing air.

Gelöst wird diese Aufgabe gemäß dem Kennzeichen des ersten Patentanspruches. Weiterbildungen ergeben sich aus den Unter­ansprüchen in Verbindung mit der Beschreibung und der Zeichnung.This object is achieved according to the characterizing part of the first claim. Further developments result from the subclaims in connection with the description and the drawing.

Der Vorteil der Erfindung besteht darin, daß nicht nur im Schöndruck sondern auch im Schön- und Widerdruck die Kraft­wirkung strömender Luft zum Anpressen eines Bogen auf den Druckzylinder ausgenutzt werden kann, was bisher nicht mög­lich war.The advantage of the invention is that the force of flowing air can be used to press a sheet onto the impression cylinder not only in face printing but also in perfecting, which was not previously possible.

Die Erfindung wird nachstehend in einem Ausführungsbeispiel anhand der Zeichnung näher beschrieben.The invention is described below in an embodiment with reference to the drawing.

Es zeigt:

  • Fig. 2 die erfindungsgemäße Vorrichtung in Seitenansicht,
  • Fig. 3 eine Ansicht in Richtung X gemäß Fig. 1, als Ausschnitt, teilweise schematisch,
  • Fig. 4 einen Koppelstelltrieb zum Anheben und Absenkenn der Vorrichtung gegenüber dem Übergabebereich (Tangentenpunkt).
It shows:
  • 1 is a side view of a sheet turning device of a multi-color rotary printing machine for straight printing and for face and back printing, schematically,
  • 2 shows the device according to the invention in side view,
  • 3 is a view in the direction X of FIG. 1, as a detail, partially schematic,
  • Fig. 4 shows a coupling actuator for raising and lowering the device relative to the transfer area (tangent point).

Im Ausführungsbeispiel ist zwischen einem Druckzylinder 1 und Druckzylinder 2 aufeinander folgender Druckwerke ein Bogen­wendezylinder 3 angeordnet. Der Durchmesser dieses Zylinders ist gleich dem Durchmesser der Druckzylinder 1, 2 und doppelt so groß wie der Durchmesser der übrigen Zylinder. Auf den Druckzylindern 1 und 2 befinden sich je zwei feststehende diametral angeordnete Greifersystem 4, 5, 6, 7.In the exemplary embodiment, a sheet-turning cylinder 3 is arranged between a printing cylinder 1 and printing cylinder 2 of successive printing units. The diameter of this cylinder is equal to the diameter of the impression cylinders 1, 2 and twice as large as the diameter of the other cylinders. On the impression cylinders 1 and 2 there are two fixed diametrically arranged gripper systems 4, 5, 6, 7.

Auf dem Bogenwendezylinder 3 sind ebenfalls zwei Sauger­systeme 8, 10 und zwei Greifersysteme 9, 11 diametral auf je einer exzentrisch zur Achse des Bogenwendezylinders 3 drehbar gelagerten Welle angeordnet.On the sheet turning cylinder 3, two suction systems 8, 10 and two gripper systems 9, 11 are also arranged diametrically on a shaft rotatably mounted eccentrically to the axis of the sheet turning cylinder 3.

In Fig. 1 ist zu sehen, wie der Bogen 13 auf der geschlos­senen Oberfläche des Druckzylinders 1 aufliegt. Die Vorder­kante des Bogens 13 ist von den Greifern des Greifersystems 4 über den Tangentenpunkt 12 hinweg geführt worden und das Bogenende hat den Tangentenpunkt erreicht. Sauger 16 des Saugersystems 8 saugen unmittelbar vor oder im Tangentenpunkt 12 das Bogenende von der Oberfläche des Druckzylinders 1 ab und die Greifer des Greifersystems 4 des Druckzylinders 1 geben den Bogen 13 frei.In Fig. 1 it can be seen how the sheet 13 rests on the closed surface of the printing cylinder 1. The front edge of the sheet 13 has been guided over the tangent point 12 by the grippers of the gripper system 4 and the end of the sheet has reached the tangent point. Suction cups 16 of the suction system 8 suck the bow end from the surface of the printing cylinder 1 immediately before or at the tangent point 12 and the grippers of the gripper system 4 of the printing cylinder 1 release the sheet 13.

Das Saugersystem 8 und das Greifersystem 9 werden während der weiteren Drehung der Zylinder 1, 2, 3 auf die Mitte des Bogenwendezylinders 3 und aufeinander zu in bekannter Weise geschwungen. Der Bogen 13 wird während der weiteren Drehung der Zylinder 1, 2, 3 von den Greifern des Greifersystems 9 übernommen. Nach erfolgter Übergabe werden beide Systeme 8, 9 in bekannter Weise wieder in die Ausgangslage zurückge­schwungen.The suction system 8 and the gripper system 9 are swung during the further rotation of the cylinders 1, 2, 3 onto the center of the sheet turning cylinder 3 and towards one another in a known manner. The bow 13 is during the further rotation of the cylinders 1, 2, 3 by the grippers of the gripper system 9 accepted. After the transfer, both systems 8, 9 are swung back into the starting position in a known manner.

Der Bogen 13 ist somit gewendet und wird vom Greifersystem 9 mit der Hinterkante voran zum nachfolgenden Tangentenpunkt geführt. Dort wird der Bogen 13 vom Greifersystem 9 an das Greifersystem 6 des Druckzylinders 2 übergeben. Das Greifer­system 6 des Druckzylinders 2 führt den gewendeten Bogen 13 zum Bedrucken der Bogenrückseite dem foglenden Druckwerk zu.The arch 13 is thus turned and is guided by the gripper system 9 with the trailing edge first to the subsequent tangent point. There, the sheet 13 is transferred from the gripper system 9 to the gripper system 6 of the printing cylinder 2. The gripper system 6 of the printing cylinder 2 leads the turned sheet 13 to the following printing unit for printing on the back of the sheet.

Ein dem Bogen 13 beim Fortdruck folgender Bogen wird in derselben Weise von den entsprechenden, zu den beschriebenen System diametral angeordneten Bogenführungssystemen, d.h. dem Greifersystem 5 auf dem Druckzylinder 1, dem Saugersystem 10 und dem Greifersystem 11 auf den Bogenwendezylinder 3 und dem Greifersystem 7 auf dem Druckzylinder 2 durch die Maschine geführt.A sheet following the sheet 13 during the printing process is in the same way by the corresponding sheet guide systems arranged diametrically to the described system, i.e. the gripper system 5 on the pressure cylinder 1, the suction system 10 and the gripper system 11 on the sheet turning cylinder 3 and the gripper system 7 on the pressure cylinder 2 through the machine.

Wird die Druckmaschine so umgestellt, daß das Greifersystem 9; 11 den Bogen 13 an der Vorderkante vom Greifersystem 4; 5 des vorhergehenden Druckzylinders 1 übernimmt, dann wird der Bogen 13 durch das Greifersystem 9; 11 zwischen den aufeinan­der folgenden Druckwerken so geführt, daß er in beiden Druckwerken auf derselben Seite bedruckt wird (Schöndruck).If the printing press is converted so that the gripper system 9; 11 the sheet 13 on the front edge of the gripper system 4; 5 of the previous printing cylinder 1 takes over, then the sheet 13 by the gripper system 9; 11 between the successive printing units so that it is printed in both printing units on the same side (face printing).

Die Schwingbewegung der Saugersysteme 8; 10 und der Greifer­systeme 9; 11 wird in diesem Fall unwirksam gemacht. Während der Umdrehung des Bogenwendezylinders 3 verbleiben die Saugersysteme 8; 10 und die Greifersysteme 9; 11 in ausgeschwungener Stellung.The oscillating movement of the suction systems 8; 10 and the gripper systems 9; 11 will be rendered ineffective in this case. During the rotation of the sheet turning cylinder 3, the suction systems 8 remain; 10 and the gripper systems 9; 11 in the swing-out position.

Zum berührungslosen Aufpressen des Bogens 13 durch Blasluft auf die Oberfläche des Druckzylinders 1 unmittelbar bis in die Übergabezone am Tangentenpunkt 12 ist eine Vor­richtung vorgesehen, die ein Blasfingertragrohr 15 aufweist, welches oberhalb des Druckzylinders 1 achsparallel verläuft und sich über die Gesamtlänge des Druckzylinders 1 erstreckt. Auf dem Blasfingertragrohr 15 sind voneinander beabstandet Blasfinger 14 drehfest angeordnet, die mit ihren unteren Luftaustrittsflächen 18 sowie Luftaustrittsöffnungen 17 aufweisenden Bereich in die Übergabezone bis zum Tangenten­punkt 12 zwichen die Sauger 16 der Greifersysteme 8; 10 geführt sind. Die Luftaustrittsfläche 18 ist der Kontur des Druckzylinders 1 angepaßt, so daß sich eine konstante Spalt­breite ergibt.For contactless pressing of the sheet 13 by blowing air onto the surface of the impression cylinder 1 directly up to the transfer zone at the tangent point 12 is a device which has a blowing finger support tube 15 which runs axially parallel above the printing cylinder 1 and extends over the entire length of the printing cylinder 1. Blown fingers 14 are arranged on the blower finger support tube 15 at a distance from one another, the area with their lower air outlet surfaces 18 and air outlet openings 17 into the transfer zone up to the tangent point 12 between the suction devices 16 of the gripper systems 8; 10 are performed. The air outlet surface 18 is adapted to the contour of the printing cylinder 1, so that there is a constant gap width.

Im Schöndruckbetrieb wird die erfindungsgemäße Vorrichtung mittels einer Verstelleinrichtung 19 aus dem Übergabebereich abgehoben und sie kann bei Schön- und Widerdruck wieder mittels dergleichen Vorrichtung abgesenkt werden. Das hierzu vorgesehene Koppelgetriebe ist in Figur 4 schematisch darge­stellt. Gemäß dem Ausführungsbeispiel (Fig. 2 und 4) weist die Verstelleinrichtung 19 je einen abgewinkelten Tragbügel 23 auf, der mit einem Arm an dem jeweiligen Ende des Blas­fingertragrohres 15 befestigt ist. Im anderen Arm des abgewinkelten Tragbügels 23 ist eine Nutkurve 24 einge­arbeitet, die an einem gestellfesten Bolzen 21 gleitet. Im Scheitelpunkt des abgewinkelten Tragbügels 23 ist ferner mittels eines Drehgelenkes 27 ein Handhebel 25 angelenkt, der einen gestellfesten Bolzen 20 aufweist. Durch Verschwenken des Handhebels 25 gegen den Uhrzeigersinn um den gestell­festen Bolzen 20 kann die Vorrichtung aus der Arbeitsstellung Schön- und Widerdruck zusammen mit den Blasfingern 14 in die in Figur 2 gestrichelt dargestellte Position 14′ abgehoben werden. Durch die Nutkurve 24 und den gestellfesten Bolzen 21 wird der kreisförmigen Schwenkbewegung des Handhebels 25 eine Schubbewegung überlagert.In straight-printing operation, the device according to the invention is lifted out of the transfer area by means of an adjusting device 19 and it can be lowered again by means of the same device in the case of perfecting. The coupling gear provided for this purpose is shown schematically in FIG. 4. According to the exemplary embodiment (FIGS. 2 and 4), the adjusting device 19 each has an angled support bracket 23 which is fastened with one arm to the respective end of the blowing finger support tube 15. In the other arm of the angled bracket 23, a groove curve 24 is incorporated, which slides on a bolt 21 fixed to the frame. At the apex of the angled support bracket 23, a hand lever 25 is further articulated by means of a swivel joint 27, which has a bolt 20 fixed to the frame. By pivoting the hand lever 25 counter-clockwise around the bolt 20 fixed to the frame, the device can be lifted from the working position perfecting together with the blowing fingers 14 into the position 14 'shown in dashed lines in Figure 2'. A pushing movement is superimposed on the circular pivoting movement of the hand lever 25 by the groove curve 24 and the bolt 21 fixed to the frame.

Durch Zurückschwenken des Handhebels 25 im Uhrzeigersinn läßt sich die erfindungsgemäße Vorrichtung wieder in die Arbeits­stellung Schön- und Widerdruck in den Übergabebereich unmittelbar zum Tangentenpunkt 12 hin absenken.By swiveling back the hand lever 25 in a clockwise direction, the device according to the invention can be lowered back into the working position perfecting and printing in the transfer area directly to the tangent point 12.

Der in den Fig. 2 und 3 durch Pfeile angedeutete Luft­strom wird über ein Luftzuführungsrohr 29 einem Kloben 28 zugeführt, der auf dem Blasfingertragrohr 15 sitzt. Das Blasfingertragrohr 15 ist an dieser Stelle mit einer Öffnung versehen, so daß der zugeführte Luftstrom in das Blasfinger­tragrohr 15 und weiter über Bohrungen 32 in den Hohlraum 31 der Blasfinger 14 gelangen kann.The air flow indicated by arrows in FIGS. 2 and 3 is fed via an air supply pipe 29 to a block 28 which is seated on the blowing finger support pipe 15. The blower finger support tube 15 is provided with an opening at this point, so that the air flow supplied can get into the blower finger support tube 15 and further via bores 32 into the cavity 31 of the blow finger 14.

Die Menge des Luftstromes ist regelbar, z.B. durch ein nicht näher dargestelltes Regelventil oder durch eine im Luftzuführungsrohr 29 zwischengeschaltete Drosselklappe 30.The amount of air flow is adjustable, e.g. by a control valve (not shown in more detail) or by a throttle valve 30 interposed in the air supply pipe 29.

Damit der Luftstrom in Abhängigkeit vom Bogenformat nur im Bereich von Anfang und Ende des Bogens 13 fließt, sind in nicht näher dargestellter Weise auf einer eintourigen Welle zwei in Umfang gegeneinander verstellbare Steuerscheiben angeordnet, die in bekannter Weise mit einem zur Freigabe des Luftstromes in den gewünschten Intervall ausgebildeten Steuerventil zusammenwirken.So that the air flow, depending on the sheet format, flows only in the area of the beginning and end of the sheet 13, two control disks, which are adjustable in circumference relative to one another, are arranged in a manner not shown on a single-speed shaft Interval trained control valve interact.

Der Bogenwendezylinder 3 weist am Umfang ferner regelmäßig über die Breite des Wendezylinders verteilt Eindrehungen 26 so auf, daß eine Kollision mit der Spitze der Blasfinger 14 in der Arbeitsstellung Schön- und Widerdruck vermiedet wird. Falls die Blasfinger 14 den Greifersystemen 9; 11 gegenüber­liegend angeordnet werden sollen, müssen diese Greifersysteme 9 bzw. 11 außerdem rechtzeitig in Richtung auf die Mitte des Bogenwendezylinders 3 während der Umdrehung der Trommel eingeschwungen sein, um im Schön- und Widerdruck, d.h. in der Arbeitsstellung, die Kollision mit den Blasfingern 14 zu vermeiden. Dies läßt sich in bekannter Weise durch Verlängerung des entsprechenden Kurvenabschnittes der Steuer­kurve erreichen. Kollisionen mit den Blasfingern 14 im Schöndruck sind nicht möglich, da die Vorrichtung bei dieser Betriebsart der Druckmaschine aus dem Übergabebereich zuvor mittels der Verstelleinrichtung 19 abgehoben werden muß.The sheet turning cylinder 3 also regularly has recesses 26 distributed over the circumference across the width of the turning cylinder so that a collision with the tip of the blowing fingers 14 is avoided in the working position perfecting. If the blowing fingers 14 the gripper systems 9; 11 to be arranged opposite one another, these gripper systems 9 and 11 must also have swung in time in the direction of the center of the sheet-turning cylinder 3 during the rotation of the drum, in order to print in perfecting, ie in the Working position to avoid the collision with the blowing fingers 14. This can be achieved in a known manner by extending the corresponding curve section of the control curve. Collisions with the blower fingers 14 in straight printing are not possible, since in this operating mode of the printing press the device has to be lifted from the transfer area beforehand by means of the adjusting device 19.
