Description

Die Erfindung betrifft eine Reinigungseinrichtung für Bogenleiteinrichtungen in Rotationsdruckmaschinen gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a cleaning device for sheet guiding devices in rotary printing presses according to the preamble of Main claim.

Aus der EP 0 004 605 A1 ist eine Wascheinrichtung für Zylinder, speziell Gummituchzylinder und Druckzylinder bekannt. Die Vorrichtung benutzt dabei eine Waschwalze, die mit Waschflüssigkeit besprüht und im Bereich der Greiferbrücke am Druckzylinder abgehoben wird. Die Waschvorrichtung kann statt der Waschwalze auch gemäß DE 3 005 469 C2 ein Reinigungstuch aufweisen, daß von einer Vorratsrolle über ein an- und abstellbares Andruckelement auf eine Schmutztuchrolle geführt wird.EP 0 004 605 A1 describes a washing device for cylinders, especially known blanket cylinders and impression cylinders. The device uses a washing roller with washing liquid sprayed and lifted off the pressure cylinder in the area of the gripper bridge becomes. The washing device can also be used instead of the washing roller according to DE 3 005 469 C2 have a cleaning cloth that a Supply roll on an on and off pressure element on a Dirty cloth roll is guided.

Es sind auch an einen zylindrischen Körper, speziell an Walzen, anstellbare Rakeleinrichtungen gemäß DE 3 627 430 A1 im Druckmaschinenbau bekannt.It's also on a cylindrical body, especially on rollers, adjustable squeegee devices according to DE 3 627 430 A1 in printing press construction known.

Nachteilig bei diesen Lösungen ist es, daß diese lediglich zum Reinigen von zylindrischen Körpern verwendbar sind.The disadvantage of these solutions is that they are only for Cleaning of cylindrical bodies can be used.

Aufgabe der Erfindung ist es, eine Reinigungsvorrichtung für Bogenleiteinrichtungen in Rotationsdruckmaschinen zu entwickeln, die mit geringem Aufwand die Oberfläche (Führungsfläche) der Bogenleiteinrichtungen reinigt.The object of the invention is to provide a cleaning device for To develop sheet guiding devices in rotary printing machines, the surface (guide surface) of the Sheet guiding devices cleans.

Gelöst wird dies durch den Hauptanspruch. Weiterbildungen ergeben sich aus den Unteransprüchen. This is solved by the main claim. Further training results itself from the subclaims.

Die Reinigungseinrichtung beseitigt die an den Bogenleiteinrichtungen anhaftenden Farb- oder Lackreste sowie sonstige Verunreinigungen. Speziell im Widerdruck ist es möglich, daß sich Farb- oder auch Lackpartikel an der Oberfläche (Führungsfläche) von Bogenleiteinrichtungen ablegen. Werden diese nicht beseitigt, so baut sich an den Bogenleiteinrichtungen punktuell Farbe/Lack auf. Diese Ablagerungen, evtl. auch in Kombination mit weiteren Verunreinigungen, bewirken, daß bedruckte Bogen verkratzt werden. Dies kann zu einer Beeinträchtigung der Druckqualität führen. Eine manuelle Reinigung der Bogenleiteinrichtungen ist oft aufgrund ungünstiger Zugänglichkeit sehr aufwendig. Die Bogenleiteinrichtungen sind im allgemeinen den Umführtrommeln, auch Transfertrommeln genannt, innerhalb einer Rotationsdruckmaschine zugeordnet. Dabei eignet sich die Erfindung insbesondere für die Anordnung von einer oder auch mehreren benachbarten Transfertrommeln mit entsprechender Bogenleiteinrichtung zwischen zwei Druckwerken oder auch von Weiterverarbeitungseinheiten, wie z.B. Lackiereinrichtungen.The cleaning device eliminates those on the sheet guiding devices adhering paint or varnish residues as well as other impurities. Especially in reverse printing it is possible that color or also paint particles on the surface (guide surface) of sheet guiding devices lay down. If these are not removed, build selectively paint / varnish on the sheet guiding devices. This Deposits, possibly also in combination with other contaminants, cause printed sheets to be scratched. This can lead to deterioration in print quality. A manual Cleaning the sheet guiding devices is often due to less favorable Accessibility very expensive. The sheet guiding devices are in general the transfer drums, also called transfer drums, assigned within a rotary printing press. It is suitable the invention particularly for the arrangement of one or also several neighboring transfer drums with corresponding ones Sheet guiding device between two printing units or also from Processing units, such as Painting equipment.

Die Reinigungseinrichtung ist insbesondere für Bogenleiteinrichtungen mit Führungsflächen mit und ohne Öffnungen, die auch Luftdüsen aufnehmen können, aber auch für mit Leitstäben gebildete Bogenleiteinrichtungen geeignet. Bezogen auf eine Transfertrommel ist die Reinigungseinrichtung In annähernd radialer Richtung beweglich angeordnet. Dies wird vorzugsweise durch elastische Federverbindungen zwischen Reinigungseinrichtung und Transfertrommel erreicht. Die elastische Anordnung der Reinigungseinrichtung gestattet die Dosierung des Anpreßdruckes der Reinigungseinrichtung gegen die Bogenleiteinrichtung. Sie ist dadurch auch in der Lage Unebenheiten oder anderen Bauteilen, wie z.B. Bogenglättern innerhalb der Führungsfläche oder auch benachbarten Druckzylindern oder Trommeln auszuweichen. Um den Kontakt mit solchen Bauteilen zu vermeiden ist vorzugsweise ein Kurvengetriebe im Bereich dieser Bauteile vorgesehen. Das Kurvengetriebe ist dabei durch je ein gestellfest oder an einem Druckzylinder bzw. einer Trommel angeordnetes Kurvenglied (Kurventräger) und je einem stirnseitig an der Transfertrommel selbst oder der Reinigungseinrichtung angeordnetes Kurvenglied (Eingriffsrolle) gebildet. Das Kurvenglied am Druckzylinder/an der Trommel oder dem Seitengestell Ist dabei das Antriebsglied. Das Kurvenglied (Eingriffsrolle) an der Transfertrommel oder der Reinigungseinrichtung ist das Abtriebsglied. Antriebsglied und Abtriebsglied bilden pro Drehung der Transfertrommel eine periodische Bewegungskopplung mit dem benachbarten Druckzylinder oder der benachbarten Trommel.The cleaning device is particularly for sheet guiding devices with guide surfaces with and without openings, which are also air nozzles can accommodate, but also for those formed with rods Sheet guiding devices suitable. Relating to a transfer drum is the cleaning device in an approximately radial direction arranged movably. This is preferably done by elastic Spring connections between cleaning device and transfer drum reached. The elastic arrangement of the cleaning device allows dosing of the contact pressure of the cleaning device against the sheet guide. It is therefore also in unevenness or other components, e.g. Sheet smoothing inside the guide surface or neighboring Dodge pressure cylinders or drums. To get in touch with Avoiding such components is preferably a cam mechanism provided in the area of these components. The cam mechanism is included by one each on the frame or on a pressure cylinder or one Drum-arranged curve link (curve carrier) and one each on the end of the transfer drum itself or the Cleaning device arranged cam member (engagement roller) educated. The curve link on the pressure cylinder / drum or the Side frame is the drive link. The cam link (engaging roller) on the transfer drum or the cleaning device is the output link. Drive member and output member form pro Rotation of the transfer drum with a periodic coupling of movement the adjacent impression cylinder or drum.

Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden. Dabei zeigen:

The invention will be explained in more detail using an exemplary embodiment. Show:
Fig. 1
the schematic structure of the cleaning device with sheet guide.

In einer Bogenrotationsdruckmaschine ist in Bogenlaufrichtung eine erste Druckeinheit durch einen Druckzylinder 3, einen Gummituchzylinder 2 und einen Plattenzylinder 1 dargestellt. Eine zweite Druckeinheit ist durch einen Druckzylinder 6 einen Gummituchzylinder 7 und einen Plattenzylinder 8 dargestellt. Zwischen den Druckeinheiten (Farb- und Feuchtwerke sind nicht gezeigt) ist eine Transfertrommel 5 angeordnet, welche zwei Greiferbrücken 9 trägt. Jede Greiferbrücke 9 ist in bekannter Weise durch eine Greiferwelle mit einer Vielzahl von Greifern und zugeordneter Greiferauflage gebildet. Der Transfertrommel 5 ist eine Bogenleiteinrichtung 4 zugeordnet, welche außerhalb der Trommel 5 mit geringem Abstand zu deren Hüllkreis angeordnet ist. Im vorliegenden Beispiel ist die Bogenleiteinrichtung durch Blas-/Saugkästen gebildet, welche eine Führungsfläche mit Öffnungen aufweisen. Am Umfang der Transfertrommel 5 ist im Bereich der Greiferbrücken 9 eine Reinigungseinrichtung 10 angeordnet. Die Reinigungseinrichtung 10 ist als kompletter Baustein in eine justierbare Aufnahme lösbar eingesetzt und arretiert, jedoch in annähernd radialer Richtung in einem begrenzten Bereich beweglich angeordnet. Dies wird durch eine elastische Federverbindung zwischen der Reinigungseinrichtung 10 und der Aufnahme oder der Transfertrommel 5 erreicht. Die Reinigungseinrichtung 10 wird weiterhin durch eine Waschwalze 12, z.B. eine Bürstenwalze und ein benachbartes saugfähiges Kissen 11, z.B. einen Schwamm gebildet, welche sich über die gesamte Breite der Bogenleiteinrichtung 4 erstrecken. Die elastische Anordnung der Reinigungseinrichtung 10 dient der Einstellung des Anpreßdruckes der Reinigungseinrichtung 10 an die Führungsfläche der Bogenleiteinrichtung 4. Sie dient aber auch der Verhinderung eines Kontaktes mit benachbarten Druckzylinder-/Trommelmantelflächen während des Reinigungsprozesses. Dies wird erreicht, indem ein Kurvengetriebe die Reinigungseinrichtung 10 vom benachbarten Druckzylinder 3, 6 fernhält. Im vorliegenden Beispiel ist das Kurvengetriebe durch einen Meßring am jeweiligen Druckzylinder 3, 6 als Kurvenglied und eine seitlich an der Reinigungseinrichtung 10 angeordnete Rolle als Eingriffsglied gebildet. Das Kurvengetriebe ist jeweils beidseitig am Maschinengestell oder dem jeweiligen Zylinder und der entsprechenden Reinigungseinrichtung 10 angeordnet.In a sheet-fed rotary printing press, there is one in the direction of sheet travel first printing unit by a printing cylinder 3, a blanket cylinder 2 and a plate cylinder 1 shown. A second Printing unit is a blanket cylinder by a printing cylinder 6 7 and a plate cylinder 8 shown. Between Printing units (inking and dampening units are not shown) is one Transfer drum 5 arranged, which carries two gripper bridges 9. Each gripper bridge 9 is in a known manner by a gripper shaft with a large number of grippers and assigned gripper pads educated. The transfer drum 5 is a sheet guiding device 4 assigned, which is outside the drum 5 at a short distance whose envelope is arranged. In the present example it is Sheet guide device formed by blowing / suction boxes, which a Have a guide surface with openings. On the circumference of the transfer drum 5 is a cleaning device in the area of the gripper bridges 9 10 arranged. The cleaning device 10 is as Complete module releasably inserted in an adjustable holder and locked, but in an almost radial direction in one limited area movably arranged. This is done by a elastic spring connection between the cleaning device 10 and the recording or the transfer drum 5 reached. The Cleaning device 10 is furthermore replaced by a washing roller 12, e.g. a brush roller and an adjacent absorbent pad 11, e.g. formed a sponge that spanned the entire width the sheet guide 4 extend. The elastic arrangement of the Cleaning device 10 is used to adjust the contact pressure the cleaning device 10 to the guide surface of the sheet guiding device 4. But it also serves to prevent contact with adjacent pressure cylinder / drum jacket surfaces during the Cleaning process. This is achieved by using a cam mechanism the cleaning device 10 from the adjacent printing cylinder 3, 6 keeps away. In the present example, the cam mechanism is through a measuring ring on the respective pressure cylinder 3, 6 as a cam member and a roller arranged laterally on the cleaning device 10 as Engagement member formed. The cam mechanism is on both sides on the machine frame or the respective cylinder and the corresponding Cleaning device 10 arranged.

Die Wirkungsweise ist wie folgt:
Zum Einsetzen der Reinigungseinrichtung 10 wird die Transfertrommel 5 in die entsprechende Einbauposition (annähernd die obere Totlage) gedreht. Die Reinigungseinrichtung 10 wird als Baustein in die Aufnahmen eingeschoben und fixiert. Jede Aufnahme ist einmal justiert und muß nicht bei jedem Einsetzen neu justiert werden. Vorher wurde, beispielsweise von einem Leitstand aus, der Papierlauf gestoppt. Ein unbeabsichtigter Druckstart mit eingebauter Reinigungseinrichtung 10 wird schaltungstechnisch damit verhindert. Die Bogenleiteinrichtung 4, speziell deren Führungsfläche wird manuell oder durch gestellfest angeordnete Düsen mit einer Reinigungsflüssigkeit besprüht. Danach wird die Druckmaschine gestartet und die Reinigungsvorrichtung 10 wird vom vorgeordneten Druckzylinder 3 an einem Kontakt gehindert und im Bogenabgang und dem nachfolgenden Bogenaufgang gegen die Führungsfläche der Bogenleiteinrichtung 4 über die Federverbindung gedrückt. Im Bereich des nachgeordneten Druckzylinders 6 wird die Reinigungsvorrichtung 10 wiederum an einem Kontakt mit dessen Mantelfläche durch die Kurvengetriebe gehindert. Die Reinigungseinrichtung 10 wird in diesen möglichen Kontaktzonen in radialer Richtung gegen die Transfertrommelmittel in einem definierten Bereich bewegt. Nach Verlassen der möglichen Kontaktzone wird die Reinigungseinrichtung 10 gegen ihren vorher bestimmten Anschlag gedrückt, so daß der erforderliche Anpreßdruck an den Führungsflächen der Bogenleiteinrichtung 4 gewährleistet ist. Die durch die Reinigungsflüssigkeit angelösten Verunreinigungen werden von der Reinigungseinrichtung 10 entfernt und aufgesogen. Im vorliegenden Beispiel entfernt die Waschwalze 12 die Verunreinigungen und das nachgeordnete saugfähige Kissen 11 nimmt das Gemisch aus Reinigungsmittel und Verunreinigungen auf. Die Reinigungseinrichtung 10 kann für mehrere Umdrehungen an der Transfertrommel 5 fixiert bleiben, bis der Reinigungserfolg eingetreten ist. Die Reinigungsflüssigkeit kann dabei mehrfach auf die Führungsflächen der Bogenleiteinrichtung 4 aufgesprüht werden.
The mode of action is as follows:
To insert the cleaning device 10, the transfer drum 5 is rotated into the corresponding installation position (approximately the top dead center). The cleaning device 10 is inserted and fixed as a module in the receptacles. Each holder is adjusted once and does not have to be readjusted every time it is inserted. Before, for example from a control center, the paper flow was stopped. An unintentional start of printing with built-in cleaning device 10 is thus prevented in terms of circuitry. The sheet guiding device 4, especially its guide surface, is sprayed with a cleaning liquid manually or through nozzles arranged fixed to the frame. The printing press is then started and the cleaning device 10 is prevented from contacting by the upstream printing cylinder 3 and pressed against the guide surface of the sheet guiding device 4 in the sheet outlet and the subsequent sheet emergence via the spring connection. In the area of the downstream pressure cylinder 6, the cleaning device 10 is in turn prevented from contacting its outer surface by the cam mechanism. The cleaning device 10 is moved in these possible contact zones in a radial direction against the transfer drum means in a defined area. After leaving the possible contact zone, the cleaning device 10 is pressed against its predetermined stop so that the required contact pressure on the guide surfaces of the sheet guiding device 4 is ensured. The contaminants dissolved by the cleaning liquid are removed and absorbed by the cleaning device 10. In the present example, the washing roller 12 removes the contaminants and the downstream absorbent pad 11 absorbs the mixture of cleaning agent and contaminants. The cleaning device 10 can remain fixed on the transfer drum 5 for several revolutions until the cleaning is successful. The cleaning liquid can be sprayed several times onto the guide surfaces of the sheet guiding device 4.

Ist der Reinigungsprozeß beendet wird die Transfertrommel 5 wieder In die Einbauposition gedreht. Die Reinigungseinrichtung 10 wird von ihrer Aufnahme gelöst und komplett herausgenommen. Nach Ausbau der Reinigungseinrichtung 10 aus der Druckmaschine kann die Einrichtung 10 separat gereinigt werden. Der Reinigungsprozeß kann vorzugsweise bei Ende eines Druckauftrages oder auch bei Schichtende eingeleitet werden. Mindestens eine Reinigungseinrichtung 10 ist dabei an der Transfertrommel 5 angeordnet. Bei zwei-, drei- oder vierfachgroßen Transfertrommeln 5 (bezogen auf einen einfachgroßen Druckzylinder) können auch zwei, drei oder vier Reinigungseinrichtungen 10 symmetrisch versetzt pro Trommel 5 angeordnet werden. Bei Bogenrotationsdruckmaschinen mit mehreren Transfertrommeln 5 können alle oder auch nur einzelne Trommeln 5 mit Reinigungseinrichtungen 10 ausgerüstet werden, die auch untereinander austauschbar sind. Die Reinigungseinrichtung 10 ist nicht auf das vorher beschriebene Beispiel einer Waschwalze 12 und einem saugfähigen Kissen 11 beschränkt. Vielmehr eignen sich hierzu auch Waschtuch und Andruckelement oder auch ein flexibles Rakelblatt oder sonstige elastische Andruckelemente. If the cleaning process is finished, the transfer drum 5 is again Rotated to the installation position. The cleaning device 10 is detached from its inclusion and completely removed. After removal the cleaning device 10 from the printing press can the device 10 to be cleaned separately. The cleaning process can preferably at the end of a print job or at the end of a shift be initiated. At least one cleaning device 10 is arranged on the transfer drum 5. With two, three or quadruple-sized transfer drums 5 (based on a single-sized Printing cylinders) can also have two, three or four cleaning devices 10 symmetrically offset per drum 5 will. For sheet-fed rotary printing presses with multiple transfer drums 5 can all or only individual drums 5 with Cleaning devices 10 are equipped, which also with each other are interchangeable. The cleaning device 10 is not to the previously described example of a washing roller 12 and one absorbent pillow 11 limited. Rather, they are also suitable for this Washcloth and pressure element or a flexible doctor blade or other elastic pressure elements.
