Abstract

A sheet guide system transfers the sheet to a printing cylinder at the speed of the latter. The sheet guide device (9) has a sheet guide plate and extends directly up to the printing cylinder at a distance and arched to the sheet guide system (2). The sheet guide plate has blower nozzles which produce a blast of air which follows the path of the sheet guide plate and is directed away from the printing cylinder. The sheet guide plate can be formed as the top side of an air box connected to a blow air source.

Description

Die Erfindung betrifft eine Bogenleiteinrichtung in der Bogenanlage einer Bogendruckmaschine, bestehend aus einer periodisch arbeitenden Schwinganlage, die einen auf einem der Schwinganlage vorgeordneten Anlegtisch mit Hilfe von aus Vorder- und Deckmarken bestehenden Anlegmarken nach der Vorderkante und durch Seitenmarken nach der Seitenkante ausgerichteten Bogen erfaßt und einem der Schwinganlage nachgeordneten, umlaufenden Bogenführungssystem übergibt, welches den Bogen mit mindestens Druckzylindergeschwindigkeit einem nachgeordneten Druckzylinder übergibt, wobei dem Bogenführungssystem Mittel zum beschleunigten Abführen des auf dem Anlegtisch befindlichen Bogens zugeordnet sind.The invention relates to a sheet guiding device in the sheet line of a sheet printing machine, consisting of a periodically operating vibration system, one on one of the Vibration system upstream feed table with the help of front and cover marks Contact marks after the front edge and through side marks after the side edge aligned arc detected and one of the vibrating system downstream, rotating Sheet guiding system, which passes the sheet with at least printing cylinder speed passes a downstream printing cylinder, the sheet guide system Means for accelerated removal of the sheet located on the feed table are.

Derartige Bogenanlagen sind z.B. nach der DE 195 23 887 und 195 23 888 bekannt.Such arch systems are e.g. known from DE 195 23 887 and 195 23 888.

Nachteilig ist bei derartigen im Großformat arbeitenden Bogenanlagen die Tatsache, dass die Leistung der Bogenanlage und damit der Gesamtmaschine dadurch begrenzt ist, dass der Folgebogen erst dann mechanisch seitlich ausgerichtet und eine sichere Doppelbogenkontrolle erreicht werden kann, wenn das Bogenende des abziehenden Bogens den Anlegtisch verlassen hat.A disadvantage of such sheetfed systems working in large format is the fact that the performance of the sheet line and thus the overall machine is limited by the fact that only then is the following sheet mechanically aligned laterally and a safe double sheet inspection can be reached when the sheet end of the pulling sheet the feed table has left.

Um diese Nachteile zu beseitigen, sind nach den DE 503 503, 724 077 Vorrichtungen zum beschleunigten Wegziehen der bereits ausgerichteten Bogen vom Anlegtisch bekannt, bei denen dem umlaufenden Bogenführungssystem Mittel zugeordnet sind, welche die von den Greifern erfaßten Bogen aus der Greiferbahn nach außen drängen. Als Mittel zum Abdrängen des Bogens aus der Greiferbahn sind z.B. Winkelhebel vorgesehen, die der Drehrichtung des Bogenführungssystems folgen und durch eine ortsfeste Kurvenscheibe gesteuert werden.
Es ist auch möglich, zum Abdrängen der Bogen eine umlaufende Bogentrommel bzw. einen Teil einer umlaufenden Zylinderoberfläche exzentrisch zum Mittelpunkt der Greiferbahn zu lagern und mit der gleichen Geschwindigkeit wie die Greifer anzutreiben oder dem Bogenführungssystem Blasdüsen oder Blasrohre zuzuordnen und durch Blasluft die Bogen vom Drehpunkt des umlaufenden Bogenführungssystems wegzuführen.In order to eliminate these disadvantages, devices for accelerating pulling of the already aligned sheets away from the feed table are known from DE 503 503, 724 077, in which means are assigned to the circumferential sheet guiding system which force the sheets detected by the grippers out of the gripper track. Angle levers, for example, are provided as means for pushing the sheet out of the gripper track, which follow the direction of rotation of the sheet guide system and are controlled by a fixed cam.
It is also possible to eject a rotating sheet drum or part of a rotating cylinder surface eccentrically to the center of the gripper track and to drive it at the same speed as the grippers or to assign blow nozzles or blow pipes to the sheet guide system and blow the sheets from the pivot point of the lead away circulating sheet guide system.

Die mechanischen Mittel zum Abdrängen der Bogen aus der Greiferbahn erfordern zu ihrer Realisierung einen hohen Aufwand und bedingen bei schnelllaufenden und großformatigen Maschinen zusätzliche Mittel zum Vorglätten der Bogen, d.h. zum Ausstreichen der Luft zwischen Bogen und Druckzylinder. The mechanical means for pushing the sheets out of the gripper track require them Realization a lot of effort and require high-speed and large format Machines additional means for pre-smoothing the sheets, i.e. to smear the air between Sheet and impression cylinder.

Die Maßnahme, die Bogen mittels dem Bogenführungssystem zugeordneter Blasdüsen aus der Greiferbahn zu drängen, ist bei großformatigen und schnelllaufenden Maschinen sowie bei der Verarbeitung dünner Bedruckstoffe aufgrund der Flatterbildung nicht möglich. Außerdem sind auch zusätzliche Mittel zum Vorglätten der Bogen erforderlich.The measure, the sheets by means of the sheet guide system associated blow nozzles pushing the gripper track is great with large-format and high-speed machines as well not possible when processing thin substrates due to fluttering. Moreover additional means for pre-smoothing the sheets are also required.

Aufgabe der Erfindung ist es, eine Bogenleiteinrichtung zum beschleunigten Abführen eines Bogens vom Anlegtisch zu schaffen, die mit einfachen Mitteln zu realisieren ist, die Bogen vorglättet und auch bei großformatigen und schnelllaufenden Maschinen sowie bei der Verarbeitung dünner Bedruckstoffe ein effektives Betreiben der Gesamtanlage ermöglicht.The object of the invention is a sheet guiding device for the accelerated removal of a To create arches from the feed table, which can be realized with simple means, the arches pre-smoothed and also for large-format and high-speed machines and for processing thin substrates enables the entire system to be operated effectively.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 oder des Anspruchs 3 gelöst.
Die erfindungsgemäße Lösung erlaubt es, mit einfachen Mitteln das freie Ende eines abziehenden Bogens beschleunigt vom Anlegtisch zu fördern, wodurch ein früheres seitliches Ausrichten des Folgebogens und eine sichere Doppelbogenkontrolle möglich ist. Außerdem wird durch die erfindungsgemäße Lösung beim Zuführen der Bogen zum Druckzylinder die zwischen Bogen und Oberfläche des Druckzylinders befindliche Luft ausgestrichen, damit die Bogen vorgeglättet sind und damit eine glatte Auflage auch bei dünnen Materialien gesichert ist.According to the invention the object is solved by the features of claim 1 or claim 3.
The solution according to the invention allows the free end of a pulling sheet to be conveyed from the feed table in an accelerated manner by simple means, as a result of which an earlier lateral alignment of the subsequent sheet and a reliable double sheet control is possible. In addition, by the solution according to the invention, when the sheets are fed to the impression cylinder, the air located between the sheet and the surface of the impression cylinder is smeared out so that the sheets are pre-smoothed and thus a smooth support is ensured even with thin materials.

An einem Ausführungsbeispiel wird die Erfindung näher erläutert. In den zugehörigen Zeichnungen zeigen

  • Fig. 2 die schematische Darstellung einer Bogenleiteinrichtung in Seitenansicht.
    • The invention is explained in more detail using an exemplary embodiment. Show in the accompanying drawings
  • 1 is a schematic representation of a sheet acceleration system in side view,
  • Fig. 2 is a schematic representation of a sheet guide device in side view.

    • In Fig. 1 ist die schematische Darstellung eines Bogenbeschleunigungssystems gezeigt, das aus einer Schwinganlage 1 und einem der Schwinganlage 1 nachgeordneten Bogenführungssystem 2, das im Ausführungsbeispiel als eine exzentrisch gelagerte Beschleunigungstrommel 3 ausgebildet ist, besteht. Dem Bogenführungssystem 2 ist ein Druckzylinder 4 nachgeordnet und der Schwinganlage 1 ein Anlegtisch 5 vorangestellt. Dem Anlegtisch 5 sind periodisch gegen die Vorderkante des Anlegtischs 5 schwingende Vordermarken 6, dem Bogenführungssystem 2 bzw. der Beschleunigungstrommel 3 Greifer 7 und dem Druckzylinder 4 Greifer 8 zugeordnet. Dem Bogenführungssystem 2 ist eine Bogenleiteinrichtung 9 zugeordnet, die aus einem sich über die gesamte Breite des Bogenführungssystems 2 erstreckenden, gewölbt zum Bogenführungssystem 2 verlaufenden Bogenleitblech 10 besteht, das sich bis zum Umfang des Druckzylinders 4 erstreckt, ohne diesen zu berühren. Im Bogenleitblech 10 sind Blasdüsen 11, die mit einer nicht dargestellten Blasluftquelle verbunden sind und einen dem Verlauf des Bogenleitblechs 10 folgenden Blasluftstrom initiieren, vorgesehen. Im Ausführungsbeispiel ist das Bogenleitblech 10 als Oberseite eines Luftkastens 12 ausgebildet, der über einen Stutzen 13 mit einer Blasluftquelle verbunden ist.In Fig. 1, the schematic representation of an arc acceleration system is shown, the from a vibration system 1 and a bow guide system downstream of the vibration system 1 2, in the exemplary embodiment as an eccentrically mounted acceleration drum 3 is formed. The sheet guiding system 2 is a printing cylinder 4 downstream and the vibrating system 1 in front of a feed table 5. The feed table 5 are periodically swinging front marks 6 against the front edge of the feed table 5, the sheet guide system 2 or the acceleration drum 3 gripper 7 and the printing cylinder 4 grippers 8 assigned. The sheet guiding system 2 is a sheet guiding device 9 assigned, which consists of a extending over the entire width of the sheet guide system 2, arched to the sheet guide system 2 extending sheet guide plate 10, that extends to the circumference of the printing cylinder 4 without touching it. In the sheet guide plate 10 are blowing nozzles 11, which are connected to a blowing air source, not shown are and initiate a blow air flow following the course of the sheet guide plate 10, is provided. In the exemplary embodiment, the sheet guide plate 10 is the top of an air box 12 formed, which is connected via a nozzle 13 to a blast air source.

    Wird ein Bogen 14 durch nicht dargestellte Mittel in Bogentransportrichtung 15 auf den Anlegtisch 5 gefördert, werden diese durch die an den Anlegtisch 5 geführten Vordermarken 6 nach der Vorderkante und durch Seitenmarken nach der Seitenkante ausgerichtet, von der an den Anlegtisch 5 positionierten Schwinganlage 1 erfaßt, nachfolgend beschleunigt und an die Greifer 7 des Bogenführungssystems 2 übergeben. Anschließend wird der Bogen 14 durch das Bogenführungssystem 2 zum Druckzylinder 4 gefördert und dabei, falls das Bogenführungssystem 2 als Beschleunigungstrommel 3 ausgebildet ist, weiter beschleunigt auf mindestens die Geschwindigkeit des Druckzylinders 4 und an die Greifer 8 übergeben. In Figur 1 ist die Bahn des Bogens 14 in Vollliniendarstellung gezeigt und zu ersehen, dass das Ende des Bogens 14 noch auf dem Anlegtisch 5 liegt, obwohl dieser bereits durch die Wirkpaarung Greifer 8/Druckzylinder 4 geführt wird, wodurch die seitliche Ausrichtung eines Folgebogens und eine Doppelbogenkontrolle nicht möglich ist.Is a sheet 14 by means not shown in the sheet transport direction 15 on the feed table 5 promoted, these are guided by the front marks 6 guided on the feed table 5 aligned to the leading edge and by side marks to the side edge from which vibrating system 1 positioned on the feed table 5, subsequently accelerated and on hand over the grippers 7 of the sheet guide system 2. Then the bow 14 conveyed through the sheet guide system 2 to the impression cylinder 4 and, if the sheet guide system 2 is designed as an acceleration drum 3, accelerates further transfer at least the speed of the pressure cylinder 4 and to the grippers 8. In Figure 1 shows the path of the sheet 14 in full line and can be seen that the End of the sheet 14 is still on the feed table 5, although this is already due to the knitting Gripper 8 / printing cylinder 4 is guided, which causes the lateral alignment of a subsequent sheet and double sheet control is not possible.

    Bei einer aktivierten Bogenleiteinrichtung 9, die Blasdüsen 11 werden mit Blasluft beaufschlagt, wird der Bogen 14 aufgrund des zwischen dem Bogenleitblech 10 und Bogen 14 wirkenden hydrodynamischen Paradoxon vom Bogenführungssystem 2 weggeführt und folgt dem Verlauf des Bogenleitbleches 10, ohne dieses zu berühren. Die Bahn des ausgelenkten Bogens 14' ist in Figur 1 gestrichelt dargestellt und zeigt, dass das freie Ende des ausgelenkten Bogens 14' eher den Anlegtisch 5 verläßt als das Bogenende des durch die Wirkpaarung Greifer 8/Druckzylinder 4 geförderten und durch das Bogenführungssystem 2 geführten Bogens 14, wodurch ein Folgebogen früher mechanisch seitlich ausgerichtet und eine sichere Doppelbogenkontrolle realisiert werden kann.
    Durch den die Bogen 14' führenden, vom Druckzylinder 4 weggerichteten Blasluftstrom der Bogenleiteinrichtung 9 und deren unmittelbare Zuordnung zum Druckzylinder 4 werden die Bogen 14' beim Zuführen zum Druckzylinder 4 geglättet, d.h. die Luft zwischen Bogen 14' und der Mantelfläche des Druckzylinders 4 wird ausgestrichen, wodurch eine glatte Auflage auch bei dünnen Materialien möglich ist.    With an activated sheet guiding device 9, the blowing nozzles 11 are blown with air, the sheet 14 is guided away from the sheet guiding system 2 due to the hydrodynamic paradox acting between the sheet guiding plate 10 and sheet 14 and follows the course of the sheet guiding plate 10 without touching it. The path of the deflected sheet 14 'is shown in broken lines in FIG. 1 and shows that the free end of the deflected sheet 14' leaves the feed table 5 rather than the sheet end of the sheet conveyed by the effective pairing of the gripper 8 / pressure cylinder 4 and guided by the sheet guiding system 2 14, which means that a subsequent sheet can be mechanically aligned laterally and a secure double sheet inspection can be implemented.
    Due to the blowing air flow of the sheet guiding device 9 leading the sheet 14 'away from the impression cylinder 4 and its direct assignment to the impression cylinder 4, the sheet 14' is smoothed when it is fed to the impression cylinder 4, ie the air between sheet 14 'and the outer surface of the impression cylinder 4 is spread out , which enables a smooth support even with thin materials.

    Es ist auch möglich, die Bogenleiteinrichtung 9 derart auszubilden, dass im Bogenleitblech 10 statt der Blasdüsen 11 an sich bekannte Saugöffnungen vorgesehen und diese mit einer Unterdruckquelle ausgebildet werden, so dass der Bogen 14 mittels Unterdruck vom Bogenführungssystem 2 weggeführt und damit ein schnelleres Abziehen des freien Endes vom Anlegtisch 5 realisiert wird. It is also possible to design the sheet guide device 9 in such a way that in the sheet guide plate 10 instead of the blowing nozzles 11 provided suction openings known per se and these with a Vacuum source are formed so that the sheet 14 by means of vacuum from the sheet guide system 2 led away and thus a faster removal of the free end from Feed table 5 is realized.
