Description

Die Erfindung betrifft eine pneumatische Bogenführungseinrichtung in einer Druckmaschine nach dem Oberbegriff des Hauptanspruches.The invention relates to a pneumatic sheet guiding device in a printing press according to the preamble of Main claim.

[Stand der Technik][State of the art]

Eine Bogenführungseinrichtung dieser Art ist aus EP 0 802 053 A1 bekannt. An einem hohlen Blasrohr sind über die Formatbreite mehrere der Krümmung eines Druckmaschinenzylinders angepasste Leitelemente angeordnet, die Austrittsöffnungen zum Anpressen des Bogens auf die Mantelfläche des Zylinders mittels Luft aufweisen. Am Blasrohr ist jedem Leitelement eine Stelleinrichtung zum Zu- und Abschalten der Blasluft zugeordnet. Dabei weist jede Stelleinrichtung ein Verschlusselement auf, welches einer zwischen jedem Leitelement und dem Blasrohr angeordneten Durchströmöffnung zugeordnet ist.A sheet guiding device of this type is out EP 0 802 053 A1 is known. On a hollow blowpipe are over the format width of several of the curvature of a printing press cylinder adapted guide elements arranged, the outlet openings for pressing the sheet onto the outer surface of the Have cylinders with air. Everyone is on the blowpipe Guide element an actuator for switching on and off Blown air assigned. Each actuator instructs Closure element, which one between each guide element and assigned to the blow pipe arranged throughflow opening is.

Aus DE 36 08 795 A1 ist eine weitere Bogenführungseinrichtung bekannt. Danach ist vor und nach einer Druckzone die Anordnung eines über die Breite des Bogens wirkenden Blasrohres mit Düsen bekannt, die zwischen Bogen und Blasrohr ein Stellelement aufweisen.Another sheet guiding device is known from DE 36 08 795 A1 known. Then the arrangement is before and after a pressure zone a blowpipe acting across the width of the arc known with nozzles, an actuator between the arc and blowpipe exhibit.

Von Nachteil ist, dass die Bogenführungseinrichtungen relativ aufwendig sind und ausschließlich mit Blasluft betreibbar sind. Aus DE 36 08 795 A1 sind unter dem Aspekt der Berücksichtigung des Bogenformates keine Hinweise zu entnehmen. Über das Bogenformat hinausgehende Luftaustrittsöffnungen wirken sich bekanntlich negativ auf die Bogenführung aus, da an den Seitenkanten der Bogen unterblasen werden kann. Dies führt zu einem unruhigen Bogenlauf und fördert die Abschmiergefahr. The disadvantage is that the sheet guiding devices are relative are complex and can only be operated with blown air are. From DE 36 08 795 A1 are taking into account the aspect no information can be found in the sheet format. Air outlet openings that go beyond the sheet format are known to have a negative effect on the sheet guidance, since can be blown at the side edges of the sheet. This leads to a restless sheet run and promotes the risk of greasing.

Aus DE 195 30 039 C2 ist eine Blaseinrichtung in einer Druckmaschine zur Unterstützung der Bogenführung auf einem zylindrischen Körper unter Vermeidung des Unterblasens der Seitenkanten und bei Berücksichtigung des Flächengewichtes bekannt. Hierbei ist ein inneres Blasrohr - bei Verarbeitung von Karton - oder das innere und ein äußeres Blasrohr - bei Verarbeitung von Papier - zur Unterstützung der Bogenführung einsetzbar. Das äußere Blasrohr weist Düsenbohrungen zur Beeinflussung des Bogens im Randbereich auf. Das innere Rohr ist zum äußeren Rohr feststehend und weist das äußere Rohr durchdringende Bohrungen auf zur Beeinflussung des Bogens im Mittenbereich. Durch Schaltventile ist wahlweise eine Blasluftbeaufschlagung des inneren Blasrohres oder des inneren und des äußeren Blasrohres realisierbar.DE 195 30 039 C2 describes a blowing device in a printing press to support the sheet guidance on a cylindrical Body while avoiding blowing the side edges and known considering the basis weight. Here is an inner blowpipe - when processing Cardboard - or the inner and one outer blowpipe - at Processing of paper - to support the sheet guidance used. The outer blow pipe has nozzle holes Influencing the arch in the edge area. The inner tube is fixed to the outer tube and faces the outer tube penetrating holes to influence the arc in the Midrange. Blowing air is optionally available through switching valves the inner blowpipe or the inner one and the outer blowpipe can be realized.

Von Nachteil ist hierbei, dass die Blaseinrichtung relativ aufwendig ist und zu wenig die unterschiedlichen Formatbreiten bogenförmiger Bedruckstoffe in einer Druckmaschine berücksichtigt. Darüber hinaus ist die Bogenführungseinrichtung ausschließlich im Blasluftbetrieb betreibbar.The disadvantage here is that the blowing device is relative is complex and too little the different format widths sheet-shaped substrates in a printing machine. In addition, the sheet guiding device can only be operated in blown air mode.

Gemäß DE-A-38 35 266 ist eine Bogenführungseinrichtung bekannt, die in zwei Betriebsweisen betreibbar ist. In der ersten Betriebsweise werden auf einem über die Breite der Druckmaschine sich erstreckenden Rohr mehrere in Abständen angeordnete, auf druckfreie Bereiche einstellbare Rollen als Bogenführungselemente eingesetzt.
In der zweiten Betriebsweise erfolgt die Bogenführung pneumatisch. Hierzu wird ein in dem Rohr gelagertes, zweites Rohr mit Blasluft beaufschlagt, welche aus über das Rohr verteilte Düsen in Richtung Bogenmaterial ausströmt. Das zweite Rohr ist mittels eines Antriebsmechanismus gekoppelt, so dass das zweite Rohr vertikal bewegbar und die Düsen des zweiten Rohres durch Öffnungen des ersten Rohres hindurchtreten können. Diese Betriebsweise ist für Bogenmaterial einsetzbar, das keine druckfreien Bereiche aufweist.According to DE-A-38 35 266, a sheet guiding device is known which can be operated in two operating modes. In the first mode of operation, a plurality of rollers arranged at intervals and adjustable to pressure-free areas are used as sheet guiding elements on a tube which extends across the width of the printing press.

Here is the blowing device formed by the sheet guide device according to the invention.

Die pneumatische Bogenführungseinrichtung hat erfindungsgemäß nachstehenden Aufbau: Es ist ein rohrförmiges Außenteil 1 vorgesehen, dass zumindest über die maximale Formatbreite einer Druckmaschine reicht und in axialer Richtung wenigstens eine Reihe von Öffnungen 3 für den Luftdurchtritt aufweist. Dabei erstrecken sich die Öffnungen 3 über das Maximalformat der Druckmaschine. Die Öffnungen 3 sind beispielsweise in einer Ausbildung in einem definierten Winkel, insbesondere im Außenbereich, schräg angeordnet, um den Bogen im Blasluftbetrieb in Förderrichtung bzw. in Richtung Seitenkante auszustreichen.The pneumatic sheet guide device has according to the invention The following structure: It is a tubular outer part 1 provided that at least over the maximum format width a printing press is sufficient and at least in the axial direction has a series of openings 3 for the passage of air. The openings 3 extend over the maximum format the printing press. The openings 3 are, for example, in training at a defined angle, especially in Outside area, arranged obliquely to the arch in the blown air mode in the direction of conveyance or in the direction of the side edge.

Die Öffnungen 3 sind z.B. bei Ausbildung der erfindungsgemäßen Bogenführungseinrichtung als Druckzylinderblasvorrichtung auf die Mantelfläche des Druckzylinders gerichtet, um Blasluftstrahlen auf den im Greiferschluß auf den Druckzylinder geführten Bogen zu richten.The openings 3 are e.g. when training the invention Sheet guiding device as a pressure cylinder blowing device directed to the outer surface of the printing cylinder to blow air on the pressure cylinder in the gripper closure directed bow.

Bei einer Ausbildung der Bogenführungseinrichtung als Saugersystem einer Wendetrommel mit einem Außenteil 1 als Saugerrohr sind an dem schwenkbar gelagerten Außenteil 1, unter Berücksichtigung der Greiferteilung in Abständen in Achsrichtung, Saugerfinger für das Ansaugen der Bogenhinterkante angeordnet. In dieser Ausbildung tragen die Saugerfinger die Öffnungen 3 für den Luftdurchtritt, welche mit dem Inneren des Außenteiles 1 (Saugerrohr) leitungsseitig in Funktionsverbindung sind. When the sheet guiding device is designed as a suction system a turning drum with an outer part 1 as a suction tube are on the pivotally mounted outer part 1, under Taking into account the gripper pitch at intervals in the axial direction, Suction fingers for sucking the trailing edge of the sheet arranged. In this training, the suction fingers wear Openings 3 for the passage of air, which with the interior of the outer part 1 (suction pipe) on the line side in functional connection are.

Dem rohrförmigen Außenteil 1 ist konzentrisch ein rohrförmiges Innenteil 2 drehbar und vorzugsweise axial bewegbar zugeordnet. Das rohrförmige Innenteil 2 weist in Achsrichtung wenigstens eine Reihe von Steueröffnungen 4 für die Steuerung des Luftdurchtrittes auf, welche sich in mehreren Abständen 8 bis 15 über die maximale Formatbreite einer Druckmaschine in Achsrichtung erstrecken. Das Maximalformat ist somit durch die Abstände 8 bis 15 definiert.
Weiterhin weist das rohrförmige Innenteil 2 in Achsrichtung formatvariabel weitere Reihen von Steueröffnungen 5, 6, 7 für die formatvariable Steuerung des Luftdurchtrittes auf, welche analog der Steueröffnungen 4 umfangsseitig am Innenteil 2 angeordnet sind.A tubular inner part 2 is concentrically assigned to the tubular outer part 1 so that it can rotate and is preferably axially movable. The tubular inner part 2 has at least one row of control openings 4 in the axial direction for controlling the passage of air, which extend at several intervals 8 to 15 across the maximum format width of a printing press in the axial direction. The maximum format is thus defined by the distances 8 to 15.
Furthermore, the tubular inner part 2 has further rows of control openings 5, 6, 7 for the variable-format control of the air passage in the axial direction, which are arranged circumferentially on the inner part 2 analogously to the control openings 4.

In jeder Reihe der Steueröffnungen 4 oder 5 oder 6 oder 7 (Innenteil 2) sind die Abstände 8 - 15 in gleicher Teilung zu den Abständen der Öffnungen 3 (Außenteil 1) angeordnet. Dabei erstrecken sich die Steueröffnungen 7 in den Abständen 11, 12 über die minimale Formatbreite einer Druckmaschine. Das Minimalformat ist somit durch die Steueröffnungen 7 mit den Abständen 11, 12 definiert. Die zwischen dem Minimalformat und dem Maximalformat angeordneten weiteren Reihen von Steueröffnungen 5 mit den Abständen 9 bis 14 bzw. Steueröffnungen 6 mit den Abständen 10 bis 13 entsprechen bevorzugt den üblicherweise in Druckmaschinen verarbeitbaren Formatbreiten. Bevorzugt sind die Reihen von Steueröffnungen 4 - 7 in Abständen 8 - 15 für das Maximalformat zu Abständen 11,12 für das Minimalformat mehrfach gestuft, insbesondere für Zwischenformate, angeordnet.In each row of control openings 4 or 5 or 6 or 7 (Inner part 2), the distances 8 - 15 are in the same division the distances between the openings 3 (outer part 1). there the control openings 7 extend at intervals 11, 12 about the minimum format width of a printing press. The Minimal format is thus through the control openings 7 with the Distances 11, 12 defined. The between the minimal format and the further format arranged further rows of control openings 5 with the distances 9 to 14 or control openings 6 with the distances 10 to 13 preferably correspond to Format widths which can usually be processed in printing presses. The rows of control openings 4-7 are preferably at intervals 8 - 15 for the maximum format at intervals of 11.12 for the minimal format has multiple levels, especially for intermediate formats, arranged.

Das Außenteil 1 und das konzentrisch eingesetzte Innenteil 2 sind stirnseitig dicht angeordnet. Zumindest das Innenteil 2 ist mittels wenigstens einer axial und/oder radial einspeisenden Versorgungsleitung mit einem Lufterzeuger verbunden, um wahlweise die Bogenführungseinrichtung mit Saugluft bzw. Blasluft zu versorgen. Zumindest das Innenteil 2 ist zum Außenteil 1 drehbar, bevorzugt zusätzlich axial bewegbar, angeordnet. Das Verdrehen des Innenteils 2 um die Achse ist manuell oder mittels einer Betätigungseinrichtung in definierten Positionen entsprechend der Reihen von Steueröffnungen 4 - 7 realisierbar.
Das Innenteil 2 ist darüber hinaus bevorzugt axial zum Außenteil 1 bewegbar. Dies ist beispielsweise bei asymmetrischer Bogenverarbeitung in der Druckmaschine von Vorteil. Hierbei ist bevorzugt nachdem umfangsseitig eine Reihe des Innenteiles 2 mit den entsprechenden Steueröffnungen 4 oder 5 oder 6 oder 7 zu einer Reihe von Öffnungen 3 des Außenteiles 1 deckungsgleich positioniert ist, das Innenteil 2 zum Außenteil 1 axial bewegbar. Dabei sind die Steueröffnungen 4 oder 5 oder 6 oder 7 um wenigstens einen Abstand der Abstände 8-15 axial versetzt bewegbar und in der Endposition fixierbar, der der Differenz von der ursprünglich symmetrischen zur asymmetrischen Bogenverarbeitung entspricht. Voraussetzung ist hierbei, dass die Abstände 8-15 von Steueröffnungen 4-7 zu den Öffnungen 3 gleich sind. Das Positionieren des Innenteiles 2 ist bevorzugt mittels Kugelrast unter Verwendung einer Betätigungseinrichtung realisierbar.The outer part 1 and the concentrically inserted inner part 2 are tightly arranged on the end face. At least the inner part 2 is connected to an air generator by means of at least one axially and / or radially feeding supply line in order to optionally supply the sheet guiding device with suction air or blown air. At least the inner part 2 is rotatable, preferably additionally axially movable, to the outer part 1. The inner part 2 can be rotated about the axis manually or by means of an actuating device in defined positions corresponding to the rows of control openings 4-7.
The inner part 2 is also preferably axially movable to the outer part 1. This is advantageous, for example, for asymmetrical sheet processing in the printing press. In this case, after a row of the inner part 2 with the corresponding control openings 4 or 5 or 6 or 7 is positioned congruently to a row of openings 3 of the outer part 1, the inner part 2 is axially movable relative to the outer part 1. The control openings 4 or 5 or 6 or 7 can be moved axially offset by at least a distance of the distances 8-15 and can be fixed in the end position, which corresponds to the difference between the originally symmetrical and asymmetrical sheet processing. The prerequisite here is that the distances 8-15 from control openings 4-7 to openings 3 are the same. The positioning of the inner part 2 can preferably be achieved by means of a ball catch using an actuating device.

Die pneumatische Bogenführungseinrichtung ist je nach Anforderung in den Betriebsarten "Blasluftbetrieb" bzw. "Saugluftbetrieb" getaktet betreibbar.The pneumatic sheet guiding device is depending on the requirement in the operating modes "blown air mode" or "suction air mode" clocked operable.

Das Außenteil 1 kann dabei gestellfest gelagert oder verdrehbar, z.B. mittels einer Betätigungseinrichtung, gelagert sein. Die verdrehbare Lagerung des Außenteils 1 ist beispielsweise vorteilhaft, wenn die Bogenführungseinrichtung als Druckzylinderblasvorrichtung in unterschiedlichen Neigungswinkeln Blasluftstrahlen auf den Bogen richten soll. The outer part 1 can be fixed to the frame or rotated, e.g. by means of an actuator his. The rotatable mounting of the outer part 1 is for example advantageous if the sheet guiding device as a pressure cylinder blowing device at different angles of inclination Blast air jets aimed at the bow.

Bevorzugt ist jede Betätigungseinrichtung mit einer zentralen Steuerung, z.B. einem Leitstand, einer Druckmaschine schaltungstechnisch verbunden, so dass zumindest das Verdrehen des Innenteils 2, bei Bedarf auch das Verdrehen des Außenteils 1, automatisiert durchführbar ist. In einer weiteren Ausbildung ist neben dem Verdrehen des Innenteils 2 auch dessen axiale Bewegung automatisiert durchführbar.Each actuating device with a central is preferred Control, e.g. a control center, a printing press in terms of circuitry connected so that at least twisting the Inner part 2, if necessary also turning the outer part 1, can be carried out automatically. In further training is in addition to the rotation of the inner part 2, its axial Movement can be carried out automatically.

Ist in der Druckmaschine ein bogenförmiger Bedruckstoff im Maximalformat zu verarbeiten, so ist das rohrförmige Innenteil 2 zu der Reihe Öffnungen 3 des Außenteiles 1 verdrehbar, derart, dass eine Überdeckung der Öffnungen 3 mit den Steueröffnungen 4 vorliegt. In dieser Position wird das Innenteil 2 zum Außenteil 1 positioniert. Soll ein bogenförmiger Bedruckstoff mit (bis zum Minimalformat) verringerter Formatbreite verarbeitet werden, so werden die über die jeweilige Formatbreite hinaus reichenden Öffnungen 3 verschlossen durch Verdrehen des Innenteils 2 (und bei Bedarf wieder freigelegt). Dazu wird das Innenteil 2 mit den Steuerbohrungen 5 oder 6 oder 7 derart verdreht, dass die jeweils relevante Reihe der Steuerbohrungen 5 oder 6 oder 7 mit den Öffnungen 3 des Außenteiles 1 in einzelner Uberdeckung steht. Die endseitig angeordneten Öffnungen 3 sind durch das verbleibende Vollmaterial des Innenteiles 2 damit verschlossen.Is an arc-shaped substrate in the printing press To process maximum format, that's the tubular inner part 2 rotatable to the row of openings 3 of the outer part 1, such that an overlap of the openings 3 with the control openings 4 is present. In this position, the inner part 2 positioned to the outer part 1. Should be an arch-shaped substrate with a reduced format width (down to the minimum format) are processed, they are over the respective format width beyond 3 openings closed by Twist the inner part 2 (and if necessary, uncovered again). For this purpose, the inner part 2 with the control holes 5 or 6 or 7 rotated so that the relevant one Row of control holes 5 or 6 or 7 with openings 3 of the outer part 1 is in individual overlap. The end arranged openings 3 are through the remaining Solid material of the inner part 2 closed with it.

Beispielsweise im Minimalformat sind lediglich die Steueröffnungen 7 im Abstand 11, 12 mit den korrespondierenden Öffnungen 3 des Außenteils 1 in Funktionsverbindung und die endseitigen Öffnungen 3 (Abstände 8 bis 10; 13 bis 15) sind verschlossen.For example, only the control openings are in minimal format 7 at a distance 11, 12 with the corresponding openings 3 of the outer part 1 in functional connection and the end Openings 3 (distances 8 to 10; 13 to 15) are closed.

Die Ausführungen sind nicht auf die hier angegebene Anzahl an Öffnungen 3 bzw. Steueröffnungen 4 bis 7 beschränkt. Vielmehr sind weitere Reihen von Steueröffnungen umfangsseitig am Innenteils 2 für unterschiedliche Formatbreiten, vorzugsweise abgestuft, anordbar. Die Öffnungen 3 sowie die Steueröffnungen 4 - 7, einschließlich weiterer Öffnungen (3 bzw. 4-7), sind bevorzugt als Bohrungen oder Schlitze ausführbar. The statements are not based on the number specified here Openings 3 and control openings 4 to 7 limited. Much more are further rows of control openings on the circumference Inner part 2 for different format widths, preferably graduated, can be arranged.
