[Stand der Technik][State of the art]

Eine Bogenleiteinrichtung dieser Art ist aus DE 201 01 835 U1 bekannt. Die Bogenleiteinrichtung ist unterhalb des Bogentransportweges in einem Abstand zum Bogenmaterial angeordnet und besteht aus wenigstens einem mit einem als Luftversorgung ausgebildeten Pneumatiksystem in Funktionsverbindung stehenden kastenförmig ausgebildeten Strömungskanal, welcher eine dem Bogenmaterial zugewandte, geschlossene Leitfläche mit mehreren eingearbeiteten Düsenöffnungen für den Luftdurchtritt aufweist. Die Leitfläche ist bevorzugt ein Leitblech und ist zu einem feststehenden, einseitig in Richtung Leitfläche offenen Strömungskanal bewegbar angeordnet. Die Leitfläche ist in oder gegen die Bogenförderrichtung verschiebbar und ist weiterhin aus der Verarbeitungsmaschine entfernbar bzw. in diese einsetzbar.
Bei Verarbeitungsmaschinen mit benachbart angeordneten, rotierenden Bogenhaltesystemen, insbesondere angeordnet an Bogenführungszylindern, und unterhalb des Bogentransportweges angeordneter Bogenleiteinrichtung liegen für die Bogenleiteinrichtung - je nach Zylinderlage - häufig beengte Platzverhältnisse vor.A sheet guiding device of this kind is made DE 201 01 835 U1 known. The sheet guiding device is arranged below the sheet transport path at a distance from the sheet material and consists of at least one with a formed as an air supply pneumatic system in operative connection box-shaped flow channel, which has a sheet material facing, closed guide surface with several incorporated nozzle openings for the passage of air. The guide surface is preferably a baffle and is arranged to be movable to a fixed flow channel open on one side in the direction of the guide surface. The guide surface is displaceable in or against the sheet conveying direction and is further removable from the processing machine or used in this.
In processing machines with adjacently arranged, rotating sheet holding systems, in particular arranged on sheet guiding cylinders, and below the sheet transport path arranged sheet guiding device are - depending on the cylinder position - often cramped space conditions for the sheet guiding device.

Derartige Bogenleitelemente können mit oder ohne Gebläse ausgebildet sein. Weiterhin können die Bogenleitelemente im Leitblech Düsen aufweisen, wobei das entsprechende Leitblech mit einem Gebläse ausgebildet ist. Das Gebläse kann dabei unterhalb des Bogenleitelementes angeordnet sein. Alternativ kann das jeweilige Bogenleitelement mit einem wenigstens eine Kammer enthaltenden, gestellfesten Kasten einen Strömungskanal bildend ausgeführt sein, wobei das Gebläse innerhalb des Kastens oder außerhalb am Kasten angeordnet ist. Die Bogenleiteinrichtung ist wenigstens aus einem ersten und einem zweiten Bogenleitelement zusammensetzbar, wobei eine Führung vorhanden ist, welche mindestens eines der Bogenleitelemente beim Zusammensetzen führt.Out DE-A-199 14 178 Another sheet guiding device is known, which comprises various configurations of sheet guiding elements, such as rods, baffles. Such sheet guiding elements can be designed with or without a fan. Furthermore, the sheet guiding elements may have nozzles in the guide plate, wherein the corresponding guide plate is formed with a blower. The blower can be arranged below the sheet guiding element. Alternatively, the respective sheet guiding element with a housing containing at least one frame-fixed box can be made a flow channel forming, wherein the fan is disposed within the box or outside the box.

[Aufgabe der Erfindung]OBJECT OF THE INVENTION

Der Erfindung liegt die Aufgabe zugrunde eine Bogenleiteinrichtung mit einer Leitfläche der eingangs genannten Art zu schaffen, deren Bewegbarkeit der Leitfläche unterhalb des Bogentransportweges eines Bogenhaltesystems und zwischen diesem Bogenhaltesystem und einem weiteren Bogenhaltesystem verbessert ist und deren Leitfläche einfacher handhabbar ist.The invention has for its object a sheet guide with a guide surface of the type mentioned above create, whose mobility of the guide surface is improved below the sheet transport path of a sheet holding system and between this sheet holding system and another sheet holding system and the guide surface is easier to handle.

Die Aufgabe wird durch die Ausbildungsmerkmale von Anspruch 1 gelöst. Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.The object is solved by the training features of claim 1. Further developments emerge from the dependent claims.

Ein erster Vorteil der Bogenleiteinrichtung ist darin begründet, dass einem für die Bogenführung in einer Rotationsdruckmaschine gestellseitig angeordneten, einseitig offenen und mit einem Pneumatiksystem gekoppelten Strömungskanal (Unterteil mit Seitenwandungen) eine bewegbare Leitfläche als Deckfläche in Führungen zugeordnet ist. Dabei ist diese Leitfläche in oder gegen die Bogenförderrichtung zum einseitig offenen Strömungskanal verschiebbar angeordnet. D.h. die Leitfläche ist nicht mit dem gestellfesten, einseitig offenen Strömungskanal verbunden, sondern ist durch am Strömungskanal angeordneten Führungen lediglich diesem Strömungskanal zwecks Bildung eines geschlossenen Strömungskanals positioniert zugeordnet.A first advantage of the sheet guiding device is due to the fact that a flow channel (lower part with side walls) arranged on the frame side for the sheet guide in a rotary printing press and unidirectionally open and coupled to a pneumatic system is assigned a movable guide surface as a cover surface in guides. In this case, this guide surface is displaceably arranged in or against the sheet conveying direction to the flow channel open on one side. That the guide surface is not connected to the frame-fixed, unilaterally open flow channel, but is assigned by arranged on the flow channel guides only this flow channel positioned to form a closed flow channel.

Ein zweiter Vorteil besteht darin, dass die Leitfläche in einem definierten Abstand unterhalb des Bogentransportweges eines Bogenhaltesystems und zwischen diesem Bogenhaltesystem und einem weiteren, d.h. vor- oder nachgeordneten Bogenhaltesystem einfacher bewegbar ist, indem der Strömungskanal gestellseitig in je einem auf einer gemeinsamen Drehachse fluchtenden Drehgelenk schwenkbar angeordnet ist und die Leitfläche zum Strömungskanal in dieser Schwenkstellung bewegbar ist. In Schwenkstellung ist der Abstand der Leitfläche zum zugeordneten Bogenhaltesystem verringert und die Leitfläche ist zwischen zwei benachbarten Bogenhaltesystemen nach oben aus der Verarbeitungsmaschine entfernbar bzw. von oben wieder einsetzbar.
Vorteilhaft ist dabei, dass die bevorzugt als Leitblech ausgebildete Leitfläche durch die schwenkbare Anordnung des Strömungskanals annähernd im vorgegebenen Krümmungsverlauf verbleibt, um zwischen zwei Bogenhaltesystemen aus der Verarbeitungsmaschine entfernt bzw. eingesetzt zu werden.A second advantage is that the guide surface at a defined distance below the sheet transport path of a sheet holding system and between this sheet holding system and another, ie upstream or downstream sheet holding system is easier to move by the flow channel frame side in a respective aligned on a common axis of rotation swivel pivot is arranged and the guide surface is movable to the flow channel in this pivotal position. In pivot position, the distance of the guide surface is reduced to the associated sheet-holding system and the guide surface is between two adjacent sheet-holding systems removable from the processing machine or reusable from above.
It is advantageous that the guide surface preferably designed as a baffle by the pivotal arrangement of the flow channel remains approximately in the predetermined curvature to be removed or used between two sheet holding systems from the processing machine.

Von Vorteil ist weiterhin, dass die Oberfläche einer derart bewegbar angeordneten Leitfläche, bevorzugt außerhalb der Rotationsdruckmaschine, reinigbar ist und anschließend wieder mit dem in der Verarbeitungsmaschine verbliebenen, einseitig offenen Strömungskanal in Funktionsverbindung bringbar ist. Alternativ kann in der Zwischenzeit eine zweite, von Verunreinigungen freie Leitfläche dem einseitig offenen Strömungskanal austauschbar zugeordnet werden, was u.a. die Stillstandszeit bzw. Rüstzeit verkürzt.A further advantage is that the surface of such a movable arranged guide surface, preferably outside the rotary printing press, can be cleaned and then again with the remaining in the processing machine, unilaterally open flow channel in functional connection can be brought. Alternatively, in the meantime, a second, impurities-free guide surface can be assigned to the unilaterally open flow channel interchangeable, which u.a. the downtime or set-up time is shortened.

Ein weiterer Vorteil besteht darin, dass die Leitfläche gegen eine zweite Leitfläche, beispielsweise mit einer anderen Düsengeometrie und/oder einer anderen Oberfläche (Struktur bzw. Beschichtung), austauschbar ist. Damit ist eine verbesserte Abstimmung der pneumatisch unterstützten Bogenführung in Abhängigkeit von dem zu verarbeitenden Bogenmaterial realisierbar.A further advantage is that the guide surface is exchangeable for a second guide surface, for example with another nozzle geometry and / or another surface (structure or coating). For an improved coordination of the pneumatically assisted bowing in response to the sheet material to be processed is feasible.

Von Vorteil ist ebenso, dass die Bogenleiteinrichtung mit einer derart bewegbaren Leitfläche für die Bogenführung in einem definierten Abstand jedem beliebigen Bogenhaltesystem zugeordnet werden kann. D.h. das Bogenhaltesystem ist bevorzugt an einem Bogenführungszylinder, beispielsweise einem Transferzylinder, einem Druckzylinder oder einer Wendetrommel, angeordnet oder es ist mit einem umlaufenden Fördersystem im Ausleger verbunden.It is also advantageous that the sheet guiding device can be associated with such a movable guide surface for sheet guiding at a defined distance any sheet-holding system. That is, the sheet holding system is preferably arranged on a sheet guiding cylinder, for example a transfer cylinder, a printing cylinder or a turning drum, or it is connected to a circulating conveyor system in the boom.

Bei rotierenden Bogenhaltesystemen liegen somit Übergabebereiche für den Bogentransport zwischen zwei benachbarten Bogenführungszylindern mit Bogenhaltesystemen bzw. einem Bogenführungszylinder (mit Bogenhaltesystem) bzw. einem umlaufenden Greiferwagen (mit Bogenhaltesystem) und einem benachbarten Bogenführungszylinder vor.In rotating sheet holding systems are thus transfer areas for the sheet transport between two adjacent sheet guiding cylinders with sheet holding systems or a sheet guiding cylinder (with sheet holding system) or a rotating gripper carriage (with sheet holding system) and an adjacent sheet guiding cylinder.

Beim bevorzugten Einsatz von wenigstens einem Bogenführungszylinder mit abgenommenen Trommelkappen, wie beispielsweise aus DE-AS 1 254 645 bekannt, oder ohne Trommelkappen mit bevorzugt sekantenförmig ausgebildeten, geraden oder gekrümmten Seitenwänden, wie beispielsweise aus DE 44 31 114 bekannt, ist es von Vorteil, dass zwischen zwei benachbarten Bogenführungszylindern (wenigstens einer mit o.g. Ausbildung) zusätzlich Platz zum Austausch einer verschiebbaren Leitfläche vorhanden ist. Eine derartige Leitfläche ist bevorzugt zwischen zwei Bogenführungszylindern nach oben verschiebbar aus den Führungen heraus bzw. in die Führungen hinein bewegbar. Dazu ist der keine Trommelkappen aufweisende Bogenführungszylinder in eine derartige Position bewegbar, dass zwischen zwei benachbarten Bogenführungszylindern ausreichend Platz für die Verschiebung (Abförderung bzw. Zuführung) der entsprechenden Leitfläche gewährleistet ist.In the preferred use of at least one sheet guiding cylinder with removed drum caps, such as from DE-AS 1 254 645 known, or without drum caps with preferably secant formed, straight or curved side walls, such as from DE 44 31 114 known, it is advantageous that between two adjacent sheet guiding cylinders (at least one with the above-mentioned training) additional space for exchanging a sliding guide surface is present. Such a guide surface is preferably movable between two sheet guiding cylinders upwardly out of the guides or into the guides. For this purpose, the sheet guide cylinder having no drum caps can be moved into such a position that sufficient space for the displacement (discharge or supply) of the corresponding guide surface is ensured between two adjacent sheet guiding cylinders.
