Description

Die Erfindung betrifft eine Bogenführungseinrichtung in einer Druckmaschine nach dem Oberbegriff des Hauptanspruches.The invention relates to a sheet guiding device in a Printing machine according to the preamble of the main claim.

[Stand der Technik][State of the art]

Eine Bogenführungseinrichtung ist beispielsweise aus EP 0306682 A2 bekannt. Die Einrichtung besteht im Wesentlichen aus zwei mit Blasluft beaufschlagten Blasleisten, die vor und nach dem durch einen Gummituchzylinder und einen Druckzylinder gebildeten Druckspalt über die Zylinderbreite achsparallel angeordnet sind. Die in Förderrichtung vordere Blasleiste ist im zwickelförmigen Raum oberhalb des einlaufenden Bogens zwischen Gummituchzylinder und Druckzylinder angeordnet. Der Blasluftstrom ist dabei auf den Gummituchzylinder, in die Druckzone selbst sowie auf die Oberseite des auf dem Druckzylinder im Greiferschluß geführten Bogens gerichtet. Die in Förderrichtung nach der Druckzone angeordnete hintere Blasleiste erzielt einen Blasluftstrom, welcher auf die Oberseite des auf dem Druckzylinder geführten Bogens und auf den Gummituchzylinder entgegen der Förderrichtung gerichtet ist. Die Erfindung beschreibt primär die Bogenführungseinrichtung im Druckbetrieb (Druck an-Stellung). Es ist darüber hinaus in der Druckpraxis gebräuchlich, dass bei abgestellten Gummituchzylinder (Druck ab-Stellung) der Blasluftbetrieb beibehalten wird, beispielsweise bei Kontrolle des Papierlaufes oder wenn ein Druckwerk nicht am Druck beteiligt ist. Der Bedruckstoff wird dann im Greiferschluß auf dem Druckzylinder durch den Druckspalt kontaktlos zum inaktiven Gummituchzylinder mittels Blasluft durch das Druckwerk gefördert.A sheet guiding device is, for example, from EP 0306682 A2 known. The setup is essentially made of two blow strips acted upon by blowing air, the front and after that by a blanket cylinder and an impression cylinder formed pressure gap across the cylinder width axially parallel are arranged. The front blow bar in the conveying direction is in the gusset-shaped space above the incoming arch arranged between blanket cylinder and impression cylinder. The Blown air flow is on the blanket cylinder in the Printing zone itself as well as on top of that on the impression cylinder the bow guided in the gripper closure. In the Direction of delivery rear blow bar arranged after the pressure zone achieves a blown air flow, which on top of the sheet guided on the impression cylinder and on the blanket cylinder is directed against the conveying direction. The Invention primarily describes the sheet guiding device in Print mode (print on position). It is also in the printing practice common that with parked blanket cylinder (Pressure down position) maintain the blown air mode , for example when checking the paper flow or if a printing unit is not involved in the printing. The Printing material is then in the gripper closure on the printing cylinder through the pressure gap contactless to the inactive blanket cylinder conveyed through the printing unit by means of blown air.

Aus dem UK-Patent GB 2267059 B ist eine Lackiereinrichtung für eine Druckmaschine bekannt, welche dem letzten Druckwerk nachgeordnet ist. Bei einem nicht am Druckvorgang bzw. einem nicht am Lackiervorgang (das Lacksystem ist abgestellt) beteiligten Lackwerk kann der Kontakt einer frisch gedruckten Oberseite des Bedruckstoffes am Formzylinder beim Durchlaufen des Druckspaltes verhindert werden. Dabei ist die Lackiereinrichtung zweiteilig als Unterteil und Oberteil ausgebildet. Das Unterteil nimmt den Gegendruckzylinder und das Oberteil den Formzylinder mit dem Lackdosiersystem auf. Bei abgestelltem Lackvorgang wird das in Drehgelenken am Unterteil gelagerte Oberteil vom Unterteil und damit vom bogenführenden Druckzylinder abgeschwenkt. Damit ist ein relativ großer Abstand zwischen Formzylinder und Druckzylinder im Druckspalt bzw. dem Lackierspalt erzielbar und der Bogen kann ohne den Einsatz von pneumatischen Bogenführungsmitteln abschmierfrei die Lackiereinrichtung passieren. Soll der Lackiervorgang erneut durchgeführt werden, so wird das Oberteil zum Unterteil und somit der Formzylinder zum bogenführenden Druckzylinder wieder angestellt. Hierbei muß der vorher entkoppelte Antrieb des Formzylinders mit dem Antrieb des Druckzylinders eingekoppelt werden.From the UK patent GB 2267059 B is a painting device known for a printing press, which the last printing unit is subordinate. With one not at the printing process or one not on the painting process (the paint system is switched off) involved coating unit can contact a freshly printed Top of the substrate on the forme cylinder as it passes through of the pressure gap can be prevented. Here is the painting facility formed in two parts as the lower part and the upper part. The lower part takes the impression cylinder and the upper part the forme cylinder with the coating system. When turned off The painting process is carried out in swivel joints on the lower part Upper part of the lower part and thus of the bow-guiding Printing cylinder swung down. This is a relatively large one Distance between forme cylinder and impression cylinder in the printing nip or the painting gap and the sheet can be made without the Use of pneumatic sheet guide means without greasing pass the painting facility. Should the painting process be carried out again, the upper part becomes the lower part and thus the forme cylinder to the sheet-guiding printing cylinder hired again. Here the previously decoupled Drive of the forme cylinder with the drive of the impression cylinder be coupled.

[Aufgabe der Erfindung]OBJECT OF THE INVENTION

Der Erfindung liegt die Aufgabe zu Grunde eine Bogenführungseinrichtung in einer Druckmaschine zu schaffen, die eine gleichmäßige Führung eines Bedruckstoffes auf einem Bogenführungszylinder gestattet und ein verbessertes Durchlaufen des Bedruckstoffes durch einen von Gummituch-/Formzylinder und Bogenführungszylinder gebildeten Druckspalt bzw. Lakkierspalt, bei inaktiven Gummituch-/Formzylinder, gewährleistet.The invention is based on the object of a sheet guiding device in a printing press to create the one uniform guidance of a printing material on a sheet guiding cylinder allowed and an improved run through the Printing material through a blanket / form cylinder and Sheet guiding cylinder formed printing gap or painting gap, with inactive blanket / form cylinders, guaranteed.

Die Aufgabe wird durch die Ausbildungsmerkmale des Hauptanspruches gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen.The task is determined by the training characteristics of the main claim solved. Further training results from the subclaims.

Bei Bogenrotationsdruckmaschinen in Reihenbauweise mit Druckwerken für den Mehrfarbendruck sind für die Inlineveredelung auch ein oder mehrere Lackwerke den Druckwerken zuordbar. Ein Lackwerk ist dabei mit einem Druckwerk vergleichbar. Der Gummituchzylinder des Druckwerkes entspricht dann bekanntlich dem Formzylinder des Lackwerkes, der mit einer Auftragwalze sowie einem Lackdosiersystem in Funktionsverbindung ist. Ein Druckzylinder ist dabei sowohl im Druckwerk als auch im Lackwerk als Bogenführungszylinder eingesetzt.For sheet-fed rotary printing presses in series with printing units for multi-color printing are for inline finishing one or more coating units can also be assigned to the printing units. On The coating unit is comparable to a printing unit. The As is known, the blanket cylinder of the printing unit then corresponds the forme cylinder of the coating unit, which has an applicator roller as well as a paint dosing system in functional connection. On Printing cylinder is both in the printing unit and in the Coating unit used as sheet guiding cylinder.

Ein erster Vorteil der erfindungsgemäßen Einrichtung ist darin begründet, dass bei einem nicht am Druckprozess beteiligten Gummituch-/Formzylinder der Freiraum im Druckspalt/Lackspalt zwischen Gummituchzylinder bzw. Formzylinder und dem Bogenführungszylinder definiert durch einen Schwenkmechanismus einstellbar ist. Ja nach Flächengewicht und/oder Elastizität des bogenförmigen Bedruckstoffes ist somit die Größe des Freiraumes durch eine Schwenkbewegung eines Gummituch-/Formzylinders mittels Schwenkmechanismus festlegbar.A first advantage of the device according to the invention is is based on the fact that one is not involved in the printing process Blanket / form cylinder the free space in the printing gap / lacquer gap between blanket cylinder or forme cylinder and the sheet guide cylinder defined by a swing mechanism is adjustable. Depending on the basis weight and / or The elasticity of the sheet-like printing material is therefore the Size of the free space through a swiveling movement of a blanket / form cylinder can be fixed using a swivel mechanism.

Von Vorteil ist weiterhin, dass zur Realisierung der Schwenkbewegung des Gummituch-/Formzylinders eine Trennung des Gummituch-/Formzylinderantriebes vom Antrieb des Bogenführungszylinders, vorzugsweise des Druckzylinders, nicht erforderlich ist. Damit ist ein Abschwenken von Gummituch/Formzylinder aus der Druck an-Stellung sowie ein Einschwenken von Gummituch-/Formzylinder in die Druck an-Stellung während des Betriebes der Druckmaschine durchführbar. Alternativ sind die Schwenkbewegungen auch beim Maschinenstillstand realisierbar.Another advantage is that to realize the pivoting movement the blanket / forme cylinder a separation of the Blanket / form cylinder drive from the drive of the sheet guide cylinder, preferably the impression cylinder, not required is. This is a swiveling of the blanket / forme cylinder from the pressure on position and swiveling in from blanket / forme cylinder to the print on position feasible during the operation of the printing press. alternative are the swiveling movements even when the machine is at a standstill realizable.

Vorteilhaft ist ebenso, dass der Gummituch-/Formzylinder in abgeschwenkter sowie in eingeschwenkter Position stets mit einer benachbarten Auftragwalze antriebsseitig in Funktionsverbindung ist. Die Auftragwalze sowie ein zugeordnetes Dosiersystem für Farbe bzw. für Lack behalten dabei ihre festgelegte Position innerhalb der Druckmaschine. Damit ist ein mögliches Antrocknen von Druckfarbe bzw. Lack auf dem Gummituchzylinder verhinderbar oder ein sonst erforderlicher Reinigungsprozeß von Gummituchzylinder-/Formzylinder ist hinfällig.It is also advantageous that the blanket / form cylinder in always swiveled in as well as in swiveled position an adjacent applicator roller in functional connection on the drive side is. The application roller and an associated one Dosing system for paint or lacquer keep theirs fixed position within the press. So that is a possible drying of printing ink or varnish on the Blanket cylinder preventable or an otherwise necessary Cleaning process of blanket cylinder / forme cylinder is obsolete.

The intermediate gear 16 is with the gear of the pressure cylinder 11 and the gear of rastered application roller 14 constantly engaged on the drive side. There is between the intermediate gear 16 (or intermediate gears) and the gear of the forme cylinder 12 on the drive side no connection.

Der Formzylinder 12 ist mit einer Lagerung 20 in einem Schwenkmechanismus 19,20,21 drehbar gelagert. Dieser Schwenkmechanismus 19-21 besteht aus wenigstens einer jeweils in einem Seitengestell 18 mit einem gestellfest angeordneten Drehgelenk 19 innenseitig schwenkbar gelagerten Tragplatte 21. Bevorzugt ist jedes im Seitengestell 18 angeordnete Drehgelenk 19 zu einem an der Innenseite des Seitengestells 18 fixierten Walzenlager 22 fluchtend angeordnet. Es ist auch eine vom Walzenlager 22 abweichende, beidseitige Anordnung des Drehgelenkes 19 realisierbar.The forme cylinder 12 is with a bearing 20 in one Swivel mechanism 19, 20, 21 rotatably mounted. This swivel mechanism 19-21 consists of at least one each in a side frame 18 with a frame fixed Swivel joint 19 on the inside pivotally mounted support plate 21. Each is preferably arranged in the side frame 18 Swivel 19 to one on the inside of the side frame 18 fixed roller bearings 22 arranged in alignment. It is also a two-sided arrangement deviating from the roller bearing 22 of the swivel 19 realizable.

Das Walzenlager 22 nimmt dabei die gerasterte Auftragwalze 14 auf. In dieser bevorzugten Ausbildung ist die Relativlage von Walzenlager 22 und Drehgelenk 19 derart, dass diese fluchten. Alternativ ist deren Relativlage auch seitenversetzt parallel ausführbar.The roller bearing 22 takes the screened applicator roller 14 on. In this preferred embodiment, the relative position of Roller bearing 22 and swivel joint 19 such that they are aligned. Alternatively, their relative position is parallel and offset laterally executable.

In Fig. 3 ist ein Schwenkmechanismus gezeigt, welcher in bevorzugter Weise durch zwei an einem Seitengestell 18 innen und außen drehbar im Drehgelenk 19 endseitig angeordnete Tragplatten 21 gebildet ist. Diese beidseitige Anordnung von Tragplatten 21 ergibt einen verbindungssteifen Schwenkmechanismus 19 - 21. Jedes Seitengestell 18 weist einen Durchbruch 24 auf, derart dass je nach Größe dieses Durchbruches 24 der Schwenkbereich der Tragplatten 21 mit dem Formzylinder 12 um die Achse des Drehgelenkes 19 definiert ist. Hierbei ist zwischen den Tragplatten 21 die Lagerung 20 für den Formzylinder 12 angeordnet.In Fig. 3 a pivot mechanism is shown, which in preferably by two on a side frame 18 inside and rotatably arranged on the outside in the swivel 19 at the end Support plates 21 is formed. This bilateral arrangement of Support plates 21 result in a connection-rigid pivot mechanism 19 - 21. Each side frame 18 has an opening 24, such that, depending on the size of this opening 24, the Swivel range of the support plates 21 with the forme cylinder 12 around the axis of the swivel 19 is defined. Here is between the support plates 21, the storage 20 for the forme cylinder 12 arranged.

Im Druck-/Lackierbetrieb ist der Formzylinder 12 in Druck an-Stellung dem Druckzylinder 11 im Druck-/Lackierspalt 17 in Kontakt zugeordnet und der Hauptantrieb erfolgt über einen Räderzug, ausgehend vom Zahnrad des Druckzylinders 11 über das Zahnrad des Formzylinders 12 zum Zahnrad der gerasterten Auftragwalze 14. Der wesentliche Kraftfluß geht im Druck/Lackierbetrieb antriebsseitig über den Räderzug von Druckzylinder 11, Formzylinder 12 und Auftragwalze14.In the printing / painting operation, the forme cylinder 12 is in the printing on position the impression cylinder 11 in the printing / painting gap 17 in Assigned contact and the main drive takes place via a Gear train, starting from the gear of the pressure cylinder 11 the gear of the forme cylinder 12 to the gear of the grid Applicator roller 14. The main flow of force is in the printing / painting operation on the drive side via the wheel train of the pressure cylinder 11, forme cylinder 12 and applicator roller 14.

Durch den Druck-/Lackierspalt 17 wird der auf der Mantelfläche des Druckzylinders 11 im Greiferschluß geführte, bogenförmige Bedruckstoff in Förderrichtung 23 transportiert und bedruckt bzw. lackiert. Synchron erfolgt der Hilfsantrieb ausgehend vom Zahnrad des Druckzylinders 11 über das Zwischenzahnrad 16 zum Zahnrad der gerasterten Auftragwalze 14. Das Zwischenrad 16 läuft bevorzugt lose ohne wesentlichen Kraftfluß mit.Through the printing / painting gap 17 is on the outer surface of the pressure cylinder 11 guided in the gripper closure, arcuate Printing material transported in conveying direction 23 and printed or varnished. The auxiliary drive is synchronous starting from the gear of the pressure cylinder 11 via the intermediate gear 16 to the gear of the screened applicator roller 14. The intermediate wheel 16 preferably runs loose without essential Power flow with.

Ist ein Druckwerk 1 bzw. hier das Lackwerk 2 nicht am Druck/Lackierprozeß beteiligt, zum Beispiel bei Kontrolle des Papierlaufes im Druckwerk 1 bzw. Lackierwerk 2, so wird der Schwenkmechanismus 19-21 betätigt. Die Tragplatten 21 schwenken synchron um die Achse des Drehgelenkes 19, so dass der Druck-/Lackierspalt 17 freigelegt ist und der Formzylinder 12 vom Druckzylinder 11 antriebsseitig getrennt ist. D. h. der Räderzug des Hauptantriebes ist entkoppelt. Der in den Tragplatten 21 gelagerte Formzylinder 12 ist dabei antriebsseitig in ständigem Kontakt zur gerasterten Auftragwalze 14, wird dabei um deren Mantelfläche geschwenkt und ist in einer definierten Position fixierbar. Antriebsseitig erfolgt der Kraftfluss ausgehend vom Zahnrad des Druckzylinders 11 über das Zwischenzahnrad 16 auf das Zahnrad der gerasterten Auftragwalze 14 und von dieser auf das Zahnrad des Formzylinders 12. Soll der Formzylinder 12 wieder am Druck-/Lackierprozeß beteiligt werden, so wird der Schwenkmechanismus 19-21 betätigt, die Tragplatten 21 mit dem Formzylinder 12 schwenken auf den Druckzylinder 11 zu und die rotierenden Zahnräder von Formzylinder 12 und Druckzylinder 11 können im Stillstand oder während des Maschinenlaufs eingekoppelt werden.If a printing unit 1 or here the coating unit 2 is not in the printing / coating process involved, for example in controlling the Paper run in the printing unit 1 or coating unit 2, so the Swivel mechanism 19-21 operated. The support plates 21 pivot synchronously around the axis of the swivel joint 19, so that the Printing / painting gap 17 is exposed and the forme cylinder 12 is separated from the pressure cylinder 11 on the drive side. I.e. the The main drive gear train is decoupled. The one in the support plates 21 mounted forme cylinder 12 is drive side in constant contact with the screened applicator roller 14 swung around their lateral surface and is in one defined position fixable. The drive side Power flow starting from the gear of the pressure cylinder 11 the intermediate gear 16 on the gear of the screened application roller 14 and from this to the gear of the forme cylinder 12. Should the forme cylinder 12 back on the printing / painting process involved, the swivel mechanism 19-21 is actuated, pivot the support plates 21 with the forme cylinder 12 to the pressure cylinder 11 and the rotating gears from Forme cylinder 12 and impression cylinder 11 can be at a standstill or be coupled in while the machine is running.

Die Druckbeistellung erfolgt hierbei mittels Lagerung 20, welche zum Beispiel als Dreiringlager ausgebildet ist. Alternativ kann die Druckbeistellung auch über die Beistellung (Schwenkbewegung) der Tragplatten 21 selbst erfolgen.The pressure is provided by means of storage 20, which is designed as a three-ring bearing, for example. Alternatively, the provision of pressure can also be made via the provision (Swivel movement) of the support plates 21 themselves.

In einer weiteren Ausführung ist der Einsatz des Zwischenrades 16 nicht erforderlich, wenn die Auftragwalze 14 mit einem separaten - vorzugsweise elektrischen - Antrieb gekoppelt ist. Beispielsweise kann dies ein Hilfsantrieb und/oder ein separater Walzenantrieb sein.
Hierbei ist der Formzylinder 12 über das stirnseitig angeordnete Zahnrad mit dem Zahnrad der Auftragwalze 14 in Eingriff. Mittels Schwenkmechanismus 19-21 ist der Formzylinder 12 wiederum um die Auftragwalze 14 mittels Drehgelenk 19 schwenkbar. Hierbei wird die Antriebsverbindung des Zahnrades des Druckzylinders 11 und des Zahnrades des Formzylinders 12 getrennt, wobei jedoch das Zahnrad des Formzylinders 12 mit dem Zahnrad der Auftragwalze 14 in Funktionsverbindung bleibt. Der Formzylinder 12 sowie Auftragwalze 14 sind auch im abgeschwenkten Zustand vom separaten Antrieb antreibbar, so dass ein mögliches Antrocknen von Lack (oder Farbe) verhindert wird. Beim Zurückschwenken des Formzylinders 12 in Richtung Druckzylinder 11 ist der separate Antrieb elektrisch derart synchronisierbar, dass das Zahnrad des Formzylinders 12 mit dem Zahnrad des Druckzylinders 11 wieder in einer definierten Winkelposition in Eingriff bringbar ist.In a further embodiment, the use of the intermediate wheel 16 is not necessary if the application roller 14 is coupled to a separate — preferably electrical — drive. For example, this can be an auxiliary drive and / or a separate roller drive.
Here, the forme cylinder 12 is in engagement with the gear of the applicator roller 14 via the gear arranged on the end face. By means of the pivot mechanism 19-21, the forme cylinder 12 can in turn be pivoted about the application roller 14 by means of a swivel joint 19. Here, the drive connection of the gear wheel of the pressure cylinder 11 and the gear wheel of the forme cylinder 12 is separated, but the gear wheel of the forme cylinder 12 remains in functional connection with the gear wheel of the applicator roller 14. The forme cylinder 12 and applicator roller 14 can also be driven by the separate drive in the pivoted-down state, so that a possible drying of lacquer (or paint) is prevented. When the forme cylinder 12 is pivoted back in the direction of the impression cylinder 11, the separate drive can be electrically synchronized in such a way that the gearwheel of the forme cylinder 12 can be brought into engagement with the gearwheel of the impression cylinder 11 again in a defined angular position.

Der Schwenkmechanismus 19-21, speziell die Tragplatte 21, ist mit einer Betätigungseinrichtung (nicht gezeigt) in Funktionsverbindung, um die Schwenkbewegungen zu realisieren. Bevorzugt ist an der Tragplatte 21 ein Zahnsegment angeordnet, welches mit einem Stellmotor mit Ritzel als Betätigungseinrichtung in Eingriff ist. Alternativ ist statt des Stellmotors mit Ritzel auch ein Arbeitszylinder, z.B. mit Gewindespindel, an der Tragplatte 21 anlenkbar.The pivot mechanism 19-21, especially the support plate 21, is with an actuating device (not shown) in functional connection, to realize the swivel movements. A toothed segment is preferably arranged on the support plate 21, which with an actuator with pinion as an actuator is engaged. Alternatively, instead of the servomotor with pinion also a working cylinder, e.g. with threaded spindle, articulated on the support plate 21.

Die vorstehenden Ausbildungsmerkmale sind nicht auf das beschriebene Ausführungsbeispiel beschränkt. Vielmehr sind die Ausbildungsmerkmale auch in beiden Lackwerken einsetzbar bzw. in einem Druckwerk wenn diese Werke nicht am Druck- bzw. Lackierprozeß beteiligt sind. Weiterhin ist das Dosiersystem 13 nicht auf eine Auftragwalze 14 mit zugeordnetem Kammerrakel 15 oder mit zugeordneter Dosierwalze beschränkt. Vielmehr sind auch hier alternative Dosiersysteme einsetzbar.The above training features are not based on that described embodiment limited. Rather are the training features can also be used in both coating plants or in a printing unit if these units are not on the printing or Painting process are involved. Furthermore, the dosing system 13 not on an applicator roller 14 with an associated chamber doctor blade 15 or limited with an associated metering roller. Much more alternative dosing systems can also be used here.

Die Antriebsverbindung von Druckzylinder 11 zur Auftragwalze 14 ist dabei nicht auf die Anordnung von einem oder mehreren Zwischenrädern 16 zwecks Bildung eines Räderzuges (Zahnradgetriebe) beschränkt. Vielmehr sind alternative getriebtechnische Lösungen, z.B. als Zugmittelgetriebe, zur Antriebsübertragung zwischen dem Druckzylinder 11 und der Auftragwalze 14 einsetzbar. The drive connection from the pressure cylinder 11 to the application roller 14 is not based on the arrangement of one or more Intermediate wheels 16 for the purpose of forming a gear train (gear transmission) limited. Rather, there are alternative transmission technology Solutions, e.g. as a traction mechanism gearbox, for drive transmission between the impression cylinder 11 and the application roller 14 used.
