The plate is fixed to a guide-section (5) next to the sheet-smoother, which is movable along the guide track along a straight guide. The plate is movably mounted on the machine frame on an axle parallel to the sheet smoother. The parts (5,6) of the guide on both sides of the smoother are also fixed to the machine frame. The cover plate has openings (14) connected to the air-gap (15) of the sheet-smoother.

Description

Die Erfindung betrifft eine Vorrichtung zur Einwirkung auf Bogen in einem Bogenausleger einer Druckmaschine, in der Bogen wahlweise einseitig oder beidseitig bedruckt werden können, wobei ein Bogenglätter zur Entrollung der Bogen bei einseitigem Druck und eine Leitvorrichtung zur berührungsfreien Führung der Bogen bei beidseitigem Druck vorgesehen sind.The invention relates to a device for acting on sheets in a sheet delivery of a printing press, in which sheets can be printed either on one side or on both sides, a sheet straightener for unrolling the sheets when printing on one side and a guide device for contact-free guidance of the sheets when printing on both sides are provided.

Bei einer aus der DD-225 409 A1 bekannten Vorrichtung der eingangs genannten Art ist der Bogenglätter an einem Hebel befestigt, der schwenkbar am Maschinengestell gelagert ist und über ein eine Kurve, eine Antriebsschwinge und eine Koppel umfassendes Getriebe mit einem Leitelement verbunden ist. Das Leitelement ist verschiebbar an einer Gradführung gelagert und läßt sich mit Hilfe des Getriebes im Schön- und Widerdruck in den im Schöndruck vom Bogenglätter eingenommenen Raum bewegen, wobei gleichzeitig der Bogenglätter unter die Bogenlaufbahn geschwenkt wird. Auf diese Weise wird im beidseitigen Druck ein Abschmieren der Farbe beim Transport der Bogen zum Auslegerstapel vermieden. Im einseitigen Druck, bei dem die Bogen zum Rollen neigen, wird das Leitelement längs der Bogenlaufbahn verschoben und der Bogenglätter in die Bogenlaufbahn geschwenkt, wobei er über die Leitbleche und Leitstäbe hinausragt, damit die Bogen angesaugt und entrollt werden können.In a device of the type mentioned at the beginning of DD-225 409 A1, the sheet straightener is attached to a lever which is pivotally mounted on the machine frame and is connected to a guide element via a gear comprising a curve, a drive rocker and a coupling. The guide element is displaceably mounted on a degree guide and can be moved with the help of the transmission in perfecting into the space occupied by the sheet straightener, while at the same time the sheet straightener is pivoted under the sheet track. In this way, in two-sided printing, smearing of the ink is avoided when the sheets are transported to the delivery stack. In one-sided printing, in which the sheets tend to roll, the guide element is displaced along the sheet path and the sheet straightener is pivoted into the sheet path, over the guide plates and guide rods protrude so that the sheets can be sucked in and unrolled.

Aus der DD 22 5411 A1 ist eine weitere Vorrichtung der eingangs genannten Art bekannt, bei der der Bogenglätter und das Leitelement zu einem Bauteil miteinander verbunden sind, das um eine zur Bogenlaufbahn parallele Achse drehbar im Maschinengestell gelagert ist. Der Bogenglätter und das Leitelement befinden sich auf entgegengesetzten Längsseiten des Bauteils und können durch eine Drehung des Bauteils um 180° jeweils in den Wirkungsbereich der Bogenlaufbahn geschwenkt werden. Das Leitelement ist an eine Luftversorgungseinrichtung anschließbar, die Austrittsöffnungen mit Blasluft beaufschlagt, so daß die Bogen unter der Wirkung der Blasluft berührungsfrei im Bogenausleger zum Bogenstapel transportiert werden können.DD 22 5411 A1 discloses a further device of the type mentioned at the outset, in which the sheet straightener and the guide element are connected to one another, which is rotatably mounted in the machine frame about an axis parallel to the sheet path. The sheet straightener and the guide element are located on opposite long sides of the component and can be pivoted into the effective range of the sheet track by rotating the component by 180 °. The guide element can be connected to an air supply device which acts on the outlet openings with blown air, so that the sheets can be transported to the sheet stack without contact in the sheet delivery under the action of the blown air.

Die bekannten Vorrichtungen sind aufwendig in der Herstellung, da der Bogenglätter und das Leitelement mit Hilfe geeigneter Getriebe bei der Umstellung von einseitigem auf beidseitigen Druck bewegt werden müssen.The known devices are complex to manufacture, since the trowel and the guide element have to be moved with the aid of suitable gears when changing from one-sided to two-sided printing.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die sich durch einen einfachen Aufbau und einen geringen Bauaufwand auszeichnet.The invention has for its object to provide a device of the type mentioned, which is characterized by a simple structure and low construction costs.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Bogenglätter ortsfest am Maschinengestell in einer in Bezug auf die Führungsbahn der Leitvorrichtung zurückgesetzten Position angebracht ist und daß ein Leitelement in Form einer Platte vorgesehen ist, die zur Abdeckung des Bogenglätters bei beidseitigem Druck in den Freiraum zwischen Bogenlaufbahn und Bogenglätter bewegbar ist.The object is achieved in that the sheet straightener is fixed to the machine frame in a position set back in relation to the guide track of the guide device and that a guide element is provided in the form of a plate which is used to cover the sheet straightener with double-sided pressure in the space between sheet track and sheet straightener is movable.

Bei der erfindungsgemäßen Vorrichtung ist ein aufwendiges Getriebe zur Koordinierung der Bewegung von Bogenglätter und Leitelement nicht erforderlich. Der Bogenglätter ist ortsfest eingebaut und benötigt daher keine bewegliche Lagerung und keine beweglichen Anschlüsse für die Zuführung von Saug- und gegebenenfalls Blasluft. Die Bewegbarkeit des plattenförmigen Leitelements läßt sich mit einfachen baulichen Maßnahmen erreichen. So kann nach einem Vorschlag der Erfindung vorgesehen sein, daß die Platte an einem dem Bogenglätter benachbarten Abschnitt der Leitvorrichtung befestigt ist, wobei dieser Abschnitt in einer Gradführung längs der Führungsbahn der Leitvorrichtung bewegbar ist. Gemäß einer anderen Ausgestaltung der Erfindung kann die Platte um eine zum Bogenglätter parallele Achse schwenkbar am Maschinengestell gelagert sein, wobei die beiderseits des Bogenglätters liegenden Abschnitte der Leitvorrichtung ebenfalls ortsfest am Maschinengestell befestigt sein können. In beiden Fällen läßt sich das plattenförmige Leitelement mit einfachen Antriebsmitteln in die jeweils gewünschte Betriebsstellung bewegen.In the device according to the invention, a complex gear mechanism for coordinating the movement of the sheet straightener and guide element is not required. The sheet straightener is installed in a fixed position and therefore requires no movable storage and no movable connections for the supply of suction and possibly blown air. The movability of the plate-shaped guide element can be achieved with simple structural measures. Thus, according to a proposal of the invention, it can be provided that the plate is attached to a section of the guide device that is adjacent to the smoothing device, this section being movable in a degree guide along the guide path of the guide device. According to another embodiment of the invention, the plate can be mounted on the machine frame so as to be pivotable about an axis parallel to the smoothing machine, wherein the sections of the guiding device lying on both sides of the smoothing machine can also be fixed in place on the machine frame. In both cases, the plate-shaped guide element can be moved into the desired operating position with simple drive means.

Eine weitere vorteilhafte Ausgestaltung der erfindungsgemäßen Vorrichtung wird dadurch erreicht, daß die Abdeckplatte an den Luftspalt des Bogenglätters anschließbare Öffnungen hat und der Bogenglätter im Schön- und Widerdruck an eine Blasluftzufuhr anschließbar ist. Durch Umstellen des Bogenglätters von Saugen auf Blasen läßt sich hierdurch auf einfache Weise bei beidseitigem Druck im Bereich des Leitelements zusätzlich Tragluft zuführen.A further advantageous embodiment of the device according to the invention is achieved in that the cover plate has openings which can be connected to the air gap of the sheet straightener and the sheet straightener can be connected to a blown air supply in the perfect and reverse printing. By switching the sheet straightener from suction to bubbles, additional air can be supplied in a simple manner with double-sided pressure in the area of the guide element.

Die Darstellung in Figur 1 zeigt einen Bogenausleger mit einem Kettenkreis 1, an dem Greifer 2 angeordnet sind, die Bogen von einem Druckwerk 3 zu einem Bogenstapel 4 transportieren. Längs der Greiferbahn ist eine aus drei Abschnitten 5, 6, 7 bestehende Leitvorrichtung angeordnet. Die Abschnitte der Leitvorrichtung bestehen aus Hohlkörpern in der Art von flachen Kästen, deren Hohlraum mit einer Blasluftzufuhr verbindbar ist. In ihren der Greiferbahn zugekehrten Fläche sind die Abschnitte 5, 6, 7 mit Luftaustrittsöffnungen 8 versehen.The illustration in FIG. 1 shows a sheet delivery with a chain circle 1, on which grippers 2 are arranged, which transport sheets from a printing unit 3 to a sheet stack 4. A guiding device consisting of three sections 5, 6, 7 is arranged along the gripper track. The sections of the guide device consist of hollow bodies in the manner of flat boxes, the cavity of which can be connected to a blown air supply. The sections 5, 6, 7 are provided with air outlet openings 8 in their surface facing the gripper track.

Zwischen den Abschnitten 5, 6 befindet sich in einem Zwischenraum ein Bogenglätter 9, der aus zwei in einem parallelen Abstand zueinander angeordneten Rohren 10 und einem Luftkasten 11 besteht, der die Rohre 10 miteinander verbindet. Der Luftkasten 11 ist wahlweise mit einer Blasluft- oder Saugluftquelle verbindbar. Der Abschnitt 5 der Leitvorrichtung ist in einer Gradführung 12 in Längsrichtung zur Greiferbahn bewegbar gelagert und kann mittels einer nicht näher dargestellten Betätigungseinrichtung wahlweise von Hand, pneumatisch oder elektrisch zwischen zwei Endstellungen hin- und herbewegt werden. An dem Abschnitt 5 der Leitvorrichtung ist auf der dem Bogenglätter 9 zugekehrten Seite ein durch eine Platte 13 mit Luftöffnungen 14 gebildetes Leitelement befestigt.Between the sections 5, 6 there is an arc straightener 9 in an intermediate space, which consists of two tubes 10 arranged at a parallel distance from one another and an air box 11 which connects the tubes 10 to one another. The air box 11 can optionally be connected to a blown air or suction air source. Section 5 of the guiding device is mounted so that it can move in the longitudinal direction of the gripper track in a degree guide 12 and can be moved back and forth between two end positions by hand, pneumatically or electrically by means of an actuating device (not shown). A guide element formed by a plate 13 with air openings 14 is fastened to the section 5 of the guide device on the side facing the sheet straightener 9.

Figur 1 zeigt den Abschnitt 5 in der für beidseitigen Druck (Schön- und Widerdruck) vorgesehenen Position. Die Platte 13 deckt in dieser Position des Abschnitts 5 den Bogenglätter 9 vollständig ab, wobei sich die Öffnungen 14 über dem Luftspalt 15 zwischen den Rohren 10 befinden, vgl. strichpunktierte Darstellung in Figur 2. Die Bogenbahn der Leitvorrichtung ist dadurch geschlossen. Zusätzlich wird dem Bogenglätter 9 Blasluft zugeführt, die durch den Luftspalt 12 und die Öffnungen 14 austritt und die Bogen beaufschlagt, um die berührungsfreie Bogenführung zu unterstützen.FIG. 1 shows section 5 in the position provided for double-sided printing (face and back printing). The plate 13 completely covers the sheet straightener 9 in this position of section 5, the openings 14 being located above the air gap 15 between the tubes 10, cf. dash-dotted representation in Figure 2. The arc path of the guide device is closed. In addition, blown air is fed to the sheet straightener 9, which exits through the air gap 12 and the openings 14 and acts on the sheets in order to support the contact-free sheet guidance.

In der für einseitigen Druck (Schöndruck) vorgesehenen Position des Abschnitts 5 befindet sich die Platte 13 seitlich neben dem Bogenglätter 9. Diese Position ist in Figur 2 gezeigt und in Figur 1 mit strichpunktierten Linien veranschaulicht. Hierbei liegt der Bogenglätter 9 frei und kann bei Bedarf eingesetzt werden, indem er an eine Saugluftquelle angeschlossen wird. Dadurch werden die an dem Bogenglätter 9 entlanggeführten Bogen angesaugt, zwischen die Rohre 10 gezogen und durch die dabei bewirkte Verformung entrollt.In the position of section 5 intended for one-sided printing (straight printing), plate 13 is located laterally next to sheet straightener 9. This position is shown in FIG. 2 and illustrated in FIG. 1 with dash-dotted lines. Here, the sheet smoother 9 is exposed and can be used if necessary by connecting it to a suction air source. As a result, the sheets guided along the sheet straightener 9 are sucked in, drawn between the tubes 10 and unrolled by the deformation caused thereby.

Bei dem in Figur 3 dargestellten Ausführungsbeispiel sind die Abschnitte 5 und 6 der Leitvorrichtung und der dazwischen liegende Bogenglätter 9 ortsfest zueinander am Maschinengestell befestigt. Die als Leitelement dienende Platte 13 ist an ihren Schmalseiten an Armen 16 befestigt, die um eine unterhalb des Bogenglätters 9 und zu diesem parallele Achse drehbar im Machinengestell gelagert sind. An einem der Arme 16 ist die Kolbenstange 17 eines pneumatischen Hubzylinders 18 befestigt, durch den das Leitelement aus seiner in Figur 3 dargestellten Position für einseitigen Druck in die strichpunktiert dargestellte Position geschwenkt werden kann, in der die Platte 13 den Bogenglätter 9 abdeckt und dadurch die Bogenbahn schließt.In the exemplary embodiment shown in FIG. 3, sections 5 and 6 of the guiding device and the sheet straightener 9 located therebetween are fixed in place on the machine frame. The plate 13 serving as a guide element is fastened on its narrow sides to arms 16 which are mounted in the machine frame so as to be rotatable about an axis parallel to the smoothing device 9 and parallel to the latter. On one of the arms 16, the piston rod 17 of a pneumatic lifting cylinder 18 is fastened, by means of which the guide element can be pivoted from its position shown in FIG. 3 for one-sided pressure into the position shown in broken lines, in which the plate 13 covers the sheet straightener 9 and thereby the Archway closes.
