Abstract
Description
Die Erfindung betrifft eine Waschvorrichtung für einen sich drehenden Zylinder in einer Druckmaschine nach dem Oberbegriff des Hauptanspruchs.The The invention relates to a washing device for a person rotating cylinder in a printing press according to the preamble of Main claim.
Im Druckprozess sind je nach Betriebszustand und Anforderungen beim Auftragwechsel die Zylinder – wie Plattenzylinder, Gummizylinder, Druckzylinder, Formzylinder – zu reinigen. Die Gummizylinderreinigung kann auch während der Auflage notwendig sein, wenn sich z. B. Papierstaub oder Fasern auf der Oberfläche des Gummituches festgesetzt haben und zu Fortdruckstörungen führen. Ebenso kann auch die Reinigung des Plattenzylinders während des Auflagendrucks notwendig werden, wenn sich durch Störungen in der Feucht- und Farbführung oder aber auch durch Störungen infolge von Papiereinflüssen die Plattenzylinderoberfläche so verändert hat, dass die Druckqualität abnimmt. Der Druckzylinder ist gegebenenfalls zu reinigen, wenn einerseits fehlerhaft Farbe auf ihn gedruckt wurde oder ein Ablegen der Farbe auf der Oberfläche störend wirksam wird.in the Printing process are dependent on the operating condition and requirements Order change the cylinders - like plate cylinder, rubber cylinder, Printing cylinder, forme cylinder - to be cleaned. The rubber cylinder cleaning may also be necessary during the edition if z. As paper dust or fibers on the surface of the blanket have led to production disruption. As well can also clean the plate cylinder during the Circulation pressure will be necessary if due to interference in the wet and color guide or by interference due to paper influences the plate cylinder surface so has changed the print quality is decreasing. Of the If necessary, clean the printing cylinder if it is faulty Color was printed on it or putting the paint on it Surface is disturbing effect.

Dadurch erfolgt das Waschen des zu reinigenden Zylinders vorteilhaft mit einer rotativen und gleichzeitig changierenden Bewegung der Waschwalze.Thereby the washing of the cylinder to be cleaned is advantageously carried out with a rotary and at the same time iridescent movement of the washing roller.
Durch diese Bewegungsformen sind bereits gute Reinigungsergebnisse erzielbar.By These forms of movement are already achievable good cleaning results.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Reinigen von Zylinderoberflächen zu schaffen, mit der der Reinigungseffekt weiter verbessert werden kann bei gleichzeitiger spürbarer Verkürzung der Waschzeit.Of the Invention is based on the object, a device for cleaning of cylinder surfaces to create, with the cleaning effect can be further improved at the same time noticeable shortening the washing time.
Erfindungsgemäß wird die Aufgabe durch eine Vorrichtung mit den Merkmalen des 1. Anspruchs gelöst.According to the invention the object by a device having the features of the first claim solved.
Die Waschwalze ist in Walzenumfangsrichtung in der an den zu reinigenden Zylinder angestellten Position mit einer Schwingung in Umfangsrichtung bewegbar, deren Periodendauer klein gegenüber der Umlaufdauer des sich drehenden Zylinders ist bzw. deren Frequenz groß gegenüber der Umlauffrequenz des Zylinders ist.The Washing roller is in the roll circumferential direction in the to be cleaned Cylinder employed position with a vibration in the circumferential direction movable, whose period is small compared to the orbital period the rotating cylinder is or whose frequency is large compared the rotational frequency of the cylinder is.
Mit der Aufprägung einer Schwingungsbewegung in Umfangsrichtung der Waschwalze in Kombination mit anderen Bewegungsformen – wie rotative Bewegung und translatorische Changierbewegung der Waschwalze – gegenüber dem zu reinigenden Zylinder, kann der Waschvorgang für jede Waschaufgabe optimal gestaltet werden.With the imprint of a vibration movement in the circumferential direction the washing roller in combination with other forms of movement - such as rotary Movement and translational traversing movement of the washing roller - opposite the cylinder to be cleaned, the washing process for every washing task can be optimally designed.
Die rotative Bewegung wird durch die Drehung der Waschwalze und des zu reinigenden Zylinders realisiert. Die Waschwalze kann im gleichen Drehrichtungssinn wie der Zylinder rotieren, so dass an der Kontaktstelle zwischen Waschwalze und Zylinder eine gegenläufige Relativbewegung der Waschwalze zur Zylindermantelfläche erzeugt wird, die zu einer guten Reinigungswirkung führt. Die Walze kann aber auch gegensinnig zum Zylinder rotieren, dann ergibt sich die Relativbewegung aus unterschiedlichen Umfangsgeschwindigkeiten von Zylinder und Waschwalze. Gemäß einer vorteilhaften Ausgestaltung der Erfindung wird der Schwingungsbewegung der Waschwalze in Umfangsrichtung noch eine Changierbewegung in axialer Richtung aufgeprägt. Die seitliche Bewegung der Waschwalze sowie die Schwingung in Umfangsrichtung erfolgt periodisch oder stochastisch. Sehr gute Reinigungseffekte werden erreicht, wenn die Frequenz der Schwingung in Umfangsrichtung im Ultraschallbereich liegt, vorzugsweise bei 20 bis 40 kHz.The Rotational movement is caused by the rotation of the washing roller and the realized to be cleaned cylinder. The washing roller can be in the same direction of rotation as the cylinder rotate, leaving at the contact point between Wash roller and cylinder an opposite relative movement the washing roller is generated to the cylinder surface, the leads to a good cleaning effect. The roller can but also rotate in opposite directions to the cylinder, then the result Relative movement from different peripheral speeds of Cylinder and washing roller. According to an advantageous embodiment the invention is the vibrational movement of the washing roller in the circumferential direction still imprinted a traversing movement in the axial direction. The lateral movement of the washing roller and the vibration in the circumferential direction occurs periodically or stochastically. Very good cleaning effects will be achieved when the frequency of the vibration in the circumferential direction in Ultrasonic range is, preferably at 20 to 40 kHz.
Die erfindungsgemäße Waschvorrichtung ist in Rotationsdruckmaschinen, insbesondere in Bogenrotationsdruckmaschinen einsetzbar. Weiterhin ist die Waschvorrichtung in bedruckstoffverarbeitenden Maschinen anwendbar.The washing device according to the invention can be used in rotary printing machines, in particular in sheet-fed rotary printing machines. Furthermore, the washing device is processed in printing material applicable to the machines.
Durch die vorgeschlagene Waschvorrichtung kann die Waschzeit insbesondere für hartnäckige Verschmutzungen deutlich verkürzt werden bei gleichzeitiger Verbesserung der Waschergebnisse.By the proposed washing device can in particular the washing time significantly reduced for stubborn dirt while improving wash results.
