Abstract
Description
Die Erfindung betrifft eine Waschvorrichtung zur Reinigung von Zylindern eines Offsetdruckwerkes, die gleichzeitig an zwei benachbarte Zylinder anstellbar ist, mit einer drehend antreibbaren Waschwalze und einer Einrichtung zum Befeuchten der Waschwalze mit einer Waschflüssigkeit.The invention relates to a washing device for cleaning cylinders Offset printing unit, which can be adjusted simultaneously to two adjacent cylinders, with a rotatably drivable washing roller and a device for moistening the Washing roller with a washing liquid.
Beim Drucken bleiben auf den Zylindern eines Offsetdruckwerks, Papierfasern und gegebenenfalls Farbreste zurück, die bei einem Auftragswechsel bzw. bei zu starker Verschmutzung entfernt werden müssen. Für diesen Zweck sind aus den DE-OS 17 61 111 und 42 08 079 Waschvorrichtungen der eingangs genannten Art zur Reinigung des mit einem Gummituch bezogenen Zylinders bekannt. Bei Bedarf sind diese Waschvorrichtungen an den Gummituchzylinder anstellbar, wobei die Waschwalze mit einer Lösungsmittel enthaltenden Waschflüssigkeit benetzt und zu dem sich drehenden Gummituchzylinder gegenläufig drehend über das Gummituch geführt wird. Bei einer Rollenrotationsdruckmaschine mit zwei Druckwerken, bei denen die Papierbahn zum Zweck des beidseitigen Bedruckens zwischen den beiden Gummizylindern durchgeführt wird, ist es aus der DE-AS 15 61 008 bekannt, an beiden Gummizylindern je eine Waschvorrichtung vorzusehen.When printing remain on the cylinders of an offset printing unit, paper fibers and if necessary, paint residues back, when changing the order or when too strong Contamination must be removed. For this purpose, DE-OS 17 61 111 and 42 08 079 washing devices of the type mentioned for cleaning of the cylinder covered with a rubber blanket. If necessary, these are Washing devices adjustable on the blanket cylinder, the washing roller with a washing liquid containing solvent and to which rotating rubber blanket cylinder counter-rotating over the rubber blanket becomes. In a web-fed rotary printing press with two printing units, in which the Paper web for double-sided printing between the two Rubber cylinders is carried out, it is known from DE-AS 15 61 008 to provide a washing device for each of the two rubber cylinders.
Aus der DE-AS 25 31 886 ist ein Verfahren bekannt, mit dem bei einer Bogenoffsetdruckmaschine der Gummituchzylinder und der Gegendruckzylinder gleichzeitig gewaschen werden können. Bei diesem Verfahren wird eine Waschvorrichtung nach Druckabstellung der Zylinder in die Betriebsstellung an den Gummizylinder angestellt, wobei das Druckwerk ohne Papierlauf betrieben wird. Nach Inbetriebnahme der Waschvorrichtung wird der Gummizylinder an den Gegendruckzylinder angestellt. Hierbei wird der Gegendruckzylinder über den Gummizylinder gereinigt, wodurch eine gesonderte Waschvorrichtung für das automatische Waschen des Gegendruckzylinders sowie der hierfür vorzusehende Bauraum eingespart werden kann. Dieses bekannte Verfahren hat jedoch den Nachteil, daß der Waschvorgang vergleichsweise zeitaufwendig ist, da das Gummituch erst während einiger Umdrehungen des Gummizylinders gewaschen werden muß, bevor der Gummizylinder an den Gegendtuckzylinder angestellt werden kann. Weiterhin ist die Reinigungswirkung des Gummituchzylinders vergleichsweise gering, so daß auch aus diesem Grund eine längere Dauer des Waschvorgangs erforderlich ist.From DE-AS 25 31 886 a method is known with which in a sheet-fed offset printing press the blanket cylinder and the impression cylinder at the same time can be washed. In this method, a washing device is used Pressure shutdown of the cylinders in the operating position on the rubber cylinder, the printing unit being operated without a paper feed. After commissioning the Washing device, the rubber cylinder is placed on the impression cylinder. Here, the impression cylinder is cleaned via the rubber cylinder, which creates a separate washing device for automatic washing of the impression cylinder and the space to be provided for this can be saved. This known method has the disadvantage that the washing process is comparatively is time consuming since the rubber blanket takes only a few turns of the Rubber cylinder must be washed before the rubber cylinder to the Counter-pressure cylinder can be turned on. Furthermore, the cleaning effect of the Blanket cylinder comparatively small, so that for this reason too longer duration of the washing process is required.
Aus FR-A 1 351 365 ist eine Waschvorrichtung mit Waschwalze zur Reinigung von zwei einfärbbaren Gummituchzylindern bekannt, wobei die Waschwalze gleichzeitig an beide Gummituchzylinder zustellbar ist.FR-A 1 351 365 describes a washing device with a washing roller for cleaning two inkable blanket cylinders known, the washing roller simultaneously is deliverable to both blanket cylinders.
Gemäß DE-A 37 36 397 ist eine Waschvorrichtung mit einem Tuch bekannt, wobei die Waschvorrichtung auf Führungsbahnen linear an einen Gummituchzylinder zuführbar ist.According to DE-A 37 36 397 a washing device with a cloth is known, the Washing device on guideways can be fed linearly to a blanket cylinder is.
Nach US-A 5,257,578 ist eine Reinigungseinrichtung zum Reinigen eines Gummituchzylinders in einer Rollenoffsetdruckmaschine bekannt, wobei die Reinigungseinrichtung eine Bürstenwalze aufweist, welche mit einer niedrigeren Antriebsgeschwindigkeit als der Gummituchzylinder betreibbar ist, wobei die Bürstenwalze in der gleichen Richtung zum Gummituchzylinder drehbar ist.According to US-A 5,257,578 is a cleaning device for cleaning a Blanket cylinder known in a web offset printing machine, the Cleaning device has a brush roller, which with a lower Drive speed as the blanket cylinder is operable, the Brush roller is rotatable in the same direction to the blanket cylinder.
Weiterhin ist gemäß DE-A 31 20 983 eine Vorrichtung zum Waschen des Gummituchzylinders mittels einer in einem Gehäuse aufgenommenen Bürstenwalze bekannt. Die Vorrichtung weist weiterhin eine Befeuchtungseinrichtung, einen Abstreifer sowie eine Auffangrinne auf.Furthermore, according to DE-A 31 20 983, a device for washing the Blanket cylinder by means of a brush roller accommodated in a housing known. The device also has a moistening device, a Scraper and a gutter.
Letztlich ist aus EP-A-0 004 605 eine Waschvorrichtung mit einer Waschwalze für Zylinder an Druckmaschinen bekannt, welche eine Steuervorrichtung aufweist, durch die die Waschwalze über die Greiferreihen eines Druckzylinders hinweghebbar ist. Ultimately, EP-A-0 004 605 describes a washing device with a washing roller for Known cylinders on printing presses, which has a control device, by which the washing roller can be lifted over the gripper rows of a printing cylinder.
Der Erfindung liegt die Aufgabe zugrunde, eine Waschvorrichtung der eingangs genannten Art zu schaffen, deren Waschwalze an beide Zylinder gleichmäßig anstellbar ist.The invention has for its object a washing device of the beginning to create mentioned type, the washing roller on both cylinders evenly is employable.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Drehachse der Waschwalze in der tangentialen Berührungsebene zweier benachbarter Zylinder bewegbar angeordnet ist. Hierdurch wird ein gleiches Anstellen der Waschwalze an beide Zylinder gewährleistet. Auf diese Weise können zwei Zylinder, beispielsweise der Gummituchzylinder und der Gegendruckzylinder oder der Gegendruckzylinder und ein Transferzylinder gleichzeitig und in direktem Kontakt mit der Waschwalze gereinigt werden. Hierbei hat sich gezeigt, daß in der Zeit, die zum alleinigen Waschen eines einzigen Zylinders auf herkömmliche Weise erforderlich ist, mit der erfindungsgemäßen Vorrichtung zwei Zylinder gereinigt werden können, wobei sich die erforderliche Reinigungszeit jeweils nach dem stärker verschmutzten Zylinder richtet. Für das gleichzeitige Reinigen des zweiten, weniger stark verschmutzten Zylinders, ist daher kein zusätzlicher Zeitaufwand erforderlich.The object is achieved in that the axis of rotation of the Wash roller in the tangential plane of contact of two adjacent cylinders is movably arranged. As a result, the washing roller is turned on the same way both cylinders guaranteed. In this way, two cylinders, for example the blanket cylinder and the impression cylinder or the impression cylinder and a transfer cylinder cleaned simultaneously and in direct contact with the washing roller become. It has been shown that in the time for washing only one single cylinder is required in a conventional manner, with the device according to the invention two cylinders can be cleaned, whereby the required cleaning time after the heavily soiled cylinder judges. For simultaneous cleaning of the second, less soiled Cylinder, therefore no additional time is required.
Die Umfangsgeschwindigkeit der Waschwalze wird vorzugsweise größer oder kleiner bemessen als die Umfangsgeschwindigkeit der Zylinder beim Waschvorgang, um zu erreichen, daß die Waschwalze auch gegenüber dem gleichlaufenden Zylinder eine Relativbewegung ausführt. Die Drehrichtung der Waschwalze wird vorteilhaft so gewählt, daß sie zu dem stärker verschmutzenden Zylinder gegenläufig ist, d.h. den gleichen Drehsinn wie der stärker verschmutzende Zylinder hat.The peripheral speed of the washing roller is preferably larger or smaller dimensioned as the peripheral speed of the cylinders during the washing process in order to achieve that the washing roller against the synchronous cylinder Executes relative movement. The direction of rotation of the washing roller is advantageously so chosen to be opposite to the more fouling cylinder, i.e. the has the same direction of rotation as the more polluting cylinder.
Erfindungsgemäß kann weiterhin vorgesehen sein, daß die Waschwalze in einer auswechselbaren Kassette angeordnet ist, die eine Befeuchtungseinrichtung, einen Abstreifer und eine Auffangrinne für das verschmutzte Waschmittel hat. Auf diese Weise kann die Waschvorrichtung für Wartungszwecke leicht ein- und ausgebaut werden. Um eine Beschädigung der Waschwalze durch die Greiferreihen eines Zylinders, beispielsweise des Druckzylinders zu vermeiden, kann erfindungsgemäß die Waschvorrichtung mit einer Steuervorrichtung versehen sein, durch die die Waschwalze über die Zylinderkanäle und die Greiferreihen der ihr zugeordneten Zylinder hinweggehoben wird.According to the invention it can further be provided that the washing roller in a replaceable cassette is arranged, the humidifier, a Scraper and a gutter for the dirty detergent. To this The washing device can easily be installed and removed for maintenance purposes become.
