Abstract
Description
Die Erfindung betrifft eine Gummituchwaschvorrichtung zum Reinigen der Gummituchdruckzylinder in Rotationsdruckmaschinen mit einem Gummituchwaschapparat, der entlang der Schienen-Längsrichtung einer an der Rotationsdruckmaschine gehaltenen und vor einem Gummituchdruckzylinder angeordneten Führungsschiene verfahrbar ist, wobei die Gummituchwaschvorrichtung eine Düsenanordnung zum Aufbringen einer Reinigungsflüssigkeit hat und wobei der Gummituchwaschapparat zumindest eine Reinigungsbürste zum Abbürsten des Gummituchdruckzylinders aufweist.The invention relates to a blanket washing device for Cleaning the blanket printing cylinders in rotary printing machines with a blanket washer running along the length of the rails one held on the rotary printing press and arranged in front of a blanket printing cylinder Guide rail is movable, the blanket washing device a nozzle arrangement for applying a Has cleaning fluid and the blanket washer at least one cleaning brush for brushing off the blanket printing cylinder having.
An Rotationsdruckmaschinen entstehen prozeßbedingt, abhängig von der Druckfarbe und dem zu bedruckenden Papier, Farb- und Papierstaubablagerungen, welche mit steigender Druckauflage zunehmen und ab einer gewissen Menge die Druckqualität negativ beeinflussen.On rotary printing presses arise depending on the process of the printing ink and the paper to be printed, color and Paper dust deposits, which increase with the print run increase and from a certain amount the print quality is negative influence.
In den meisten Fällen werden die Gummituchdruckzylinder während eines Maschinenstop manuell gereinigt, was neben dem Aufwand auch Sicherheitsrisiken für das Personal darstellt, da die Zylinder motorisch getrieben rotieren.In most cases, the blanket cylinders are during a machine stop cleaned manually, which in addition to the effort also represents security risks for the personnel, since the cylinders rotate driven by a motor.
Seit geraumer Zeit werden automatisierte Gummituchwaschsysteme zum Reinigen der Gummituchdruckzylinder eingesetzt. Diese Systeme basieren auf einer rotierenden Bürste oder einem sich im Takt abwickelnden Reinigungstuch, welche über ein Düsensprühsystem mit Waschmittel und Wasser benetzt werden. Durch ein Anstellen an den rotierenden Gummituchdruckzylinder entsteht der Reinigungsvorgang. So hat man bereits eine Reinigungsvorrichtung geschaffen, die eine sich im wesentlichen über die gesamte Länge des zu reinigenden Druckzylinders erstreckende und in Längsrichtung am Druckzylinder anliegende Reinigungsbürste aufweist (vgl. EP-A-0 419 289).Automated blanket washing systems have been used for some time used to clean the blanket printing cylinder. This Systems are based on a rotating brush or one cleaning cloth, which unwinds in time, which over a Nozzle spray system can be wetted with detergent and water. By lining up with the rotating blanket printing cylinder the cleaning process arises. So you already have one Cleaning device created, which is essentially a over the entire length of the printing cylinder to be cleaned extending and lying in the longitudinal direction on the impression cylinder Has cleaning brush (see. EP-A-0 419 289).
Aus der DE 44 12 821 ist es bereits bekannt, den auf den Gummituchdruckzylindern befindlichen Schmutz mit Hilfe erhitzten Wassers oder Wasserdampfs anzulösen. Ansonsten arbeiten die meisten vorbekannten Systeme zum Reinigen des Gummituchdruckzylinders unter Anwendung von Waschmitteln.From DE 44 12 821 it is already known that on the blanket printing cylinders Any dirt found with the help of heated Water or water vapor to dissolve. Otherwise they work most known systems for cleaning the blanket printing cylinder using detergents.
Derartige Gummituchwaschsysteme sind ausschließlich fest dem Gummituchdruckzylinder zugeordnet und werden eingesetzt, um im bestimmtem Zyklus, nach einer Anzahl von Drucken und nach Produktionsende, den Gummituchdruckzylinder zu waschen. Durch dieses Waschen werden die Farb- und Papierstaubablagerungen abgewaschen. Das frisch gereinigte Gummituch des Gummituchdruckzylinders gewährleistet einen qualitativ ordnungsgemäßen Fortdruck der laufenden Druckauflage oder die ordnungsgemäße Startbedingung nach einem Auftragswechsel.Such blanket washing systems are only fixed Blanket printing cylinders are assigned and are used to im certain cycle, after a number of prints and after End of production to wash the blanket printing cylinder. By this washing becomes the paint and paper dust deposits washed. The freshly cleaned rubber blanket of the Blanket printing cylinder ensures a qualitative proper printing of the current print run or the proper starting conditions after a job change.
Die Waschsysteme werden meist automatisch zugeschaltet, an den Gummituchdruckzylinder angestellt und über ein definiertes Waschprogramm vom Bedienungspult der Rotation oder über einen Leitrechner gestartet. The washing systems are usually switched on automatically Blanket printing cylinder started and over a defined Washing program from the control panel of the rotation or via a Master computer started.
Aus der US-A 4 555 989 ist eine Gummituchwaschvorrichtung bekannt, die einen Gummituchwaschapparat hat, der an einer an der Rotationsdruckmaschine befestigten Führungsschiene in Schienen-Längsrichtung verfahrbar ist. Der Gummituchwaschapparat weist zum Reinigen des ihm zugeordneten Gummituchdruckzylinders eine Reinigungsbürste und ein Reinigungstuch auf, welches Reinigungstuch in einem zwischen einer Abwickelwalze und einer Aufwickelwalze vorgesehenen Teilbereich an dem Gummituchdruckzylinder angedrückt wird. Um eine Reinigungsflüssigkeit aufbringen zu können, sind in den Gummituchwaschapparat der vorbekannten Vorrichtung Flüssigkeitsbehälter und Flüssigkeitspumpen integriert. Die durch den Gummituchdruckzylinder verschmutzte Reinigungsflüssigkeit wird anschließend in einer unterhalb der Reinigungsbürste angeordneten Wanne aufgefangen. Da die in den Gummituchwaschapparat integrierten Flüssigkeitsbehälter nur einen begrenzten Vorrat haben, da die zum Auffangen der Schmutzflüssigkeit vorgesehene Wanne manuell entleert werden muß, und da jeder Gummituchwaschapparat der vorbekannten Vorrichtung jeweils nur einem Gummituchdruckzylinder fest zugeordnet ist, ist die aus US-A 4 555 989 vorbekannte Vorrichtung mit einem hohen Aufwand in Konstruktion und Handhabung verbunden.A blanket washing device is known from US Pat. No. 4,555,989, who has a blanket washer attached to one on the Rotary printing machine fastened guide rail in the longitudinal direction of the rail is movable. The blanket washer points to clean the rubber blanket cylinder assigned to it Cleaning brush and a cleaning cloth on which cleaning cloth in one between an unwinding roller and a winding roller provided section on the blanket printing cylinder is pressed. To apply a cleaning liquid to be in the blanket washer of the known Device liquid container and liquid pumps integrated. The soiled by the blanket printing cylinder Cleaning liquid is then in a below the Cleaning brush arranged in the tub. Since the in the Blanket washer built-in liquid container only have a limited supply, as those for collecting the The drain pan provided for the dirty liquid can be emptied manually must, and since each blanket washer of the known device only permanently assigned to one blanket printing cylinder is the device previously known from US-A 4,555,989 a lot of effort in construction and handling.
Aus der EP 0 747 219 A2 ist eine Reinigungsvorrichtung für Druckmaschinenzylinder bekannt, die eine sich im wesentlichen über die gesamte Länge des zu reinigenden Gummituch- oder dergleichen -druckzylinders erstreckende Reinigungsbürste hat. Diese Reinigungsbürste ist in einem Gehäuse angeordnet, das bis auf eine an den Druckzylinder angenäherte Reinigungsöffnung geschlossen ist. Die vorbekannte Reinigungsvorrichtung weist eine Absaugung auf, deren Absaugöffnungen die Reinigungsöffnungen umgrenzen. Das während des Reinigungsvorganges im Vorrichtungsgehäuse vorhandene Gemisch von Reinigungsfluid, Reinigungsdampf, Farbpartikeln und Schmutz kann somit aus dem Reinigungsgehäuse abgesaugt und ein Austreten von Reinigungsfluid und Schmutz aus dem Bereich der Reinigungsöffnung vermieden werden.EP 0 747 219 A2 describes a cleaning device for Printing press cylinders are known which are essentially one over the entire length of the blanket or the like to be cleaned -pressure cylinder-extending cleaning brush. This cleaning brush is arranged in a housing that up closed on a cleaning opening approximated to the pressure cylinder is. The known cleaning device has one Suction on, the suction openings, the cleaning openings circumscribe. That during the cleaning process in the device housing existing mixture of cleaning fluid, cleaning steam, Color particles and dirt can thus come out of the cleaning housing aspirated and leakage of cleaning fluid and Dirt from the area of the cleaning opening can be avoided.
Der Nachteil aller sich am Markt befindlichen Gummituchwaschsysteme ist die feste Zuordnung zum Gummituchdruckzylinder. Diese macht eine aufwendige Integration beziehungsweise Montage notwendig. Zudem sind bei jedem Rotationsmaschinentyp und Rotationsmaschinenformat zylinderumfangsabhängig entsprechende konstruktive mechanische Anpassungen am Gummituchwaschsystem und an der Rotationsmaschine erforderlich.The disadvantage of all blanket washing systems on the market is the fixed assignment to the blanket printing cylinder. This makes complex integration or assembly necessary. In addition, for each type of rotary machine and rotary machine format corresponding design dependent on the cylinder circumference mechanical adjustments to the blanket washing system and required on the rotary machine.
Nachteilig ist auch, wenn die vorbekannten Gummituchwaschsysteme die Breite des zu reinigenden Zylinders haben, da durch die feste Installation und Zuordnung zum jeweiligen Gummituchdruckzylinder der Druckzylinder verbaut und dessen Zugänglichkeit für das Bedienpersonal eingeschränkt ist. So können die sich auf dem Gummituchdruckzylinder befindlichen Gummitücher, welche durch Beschädigung oder oder Abnutzung während oder nach dem Produktionsprozeß gewechselt werden müssen, nur gewechselt werden, wenn das jeweilige Gummituchwaschsystem ausgebaut und entfernt wird.Another disadvantage is when the previously known blanket washing systems have the width of the cylinder to be cleaned because of fixed installation and assignment to the respective blanket printing cylinder the pressure cylinder installed and its accessibility is restricted for the operating personnel. So they can blankets located on the blanket printing cylinder, caused by damage or wear during or after the production process need to be changed, just changed when the respective blanket washing system is removed and Will get removed.
Ein weiterer Nachteil ist, daß die Systeme durch die feste Zuordnung zum jeweiligen Gummituchdruckzylinder in der Regel untereinander nicht austauschbar und analog der Anzahl von Gummituchdruckzylindern auch Gummituchwaschsysteme zu installieren sind.Another disadvantage is that the systems are hard-coded to the respective blanket printing cylinder usually with each other not interchangeable and analogous to the number of blanket printing cylinders also to install blanket washing systems are.
Ein weiterer Nachteil ist der durch den hohen technischen Aufwand bedingte Service-, Reinigungs- und Unterhaltsaufwand.Another disadvantage is the high technical effort conditional service, cleaning and maintenance expenses.
Weitere Nachteile sind, daß durch die notwendige Anwendung von Waschmittel und Wasser zwei Mittel angewendet werden, welche je nach Verschmutzungsgrad der Gummituchdruckzylinder nicht effizient genug sind bzw. eine entsprechende Waschdauer erforderlich machen. Ebenso die Tatsache, daß systembedingt nach dem Reinigungsprozeß, in der Regel bei den Bürstensystemen, der Gummituchdruckzylinder nicht abgetrocknet ist. Dies kann je nach den Bedingungen in der Rotationsdruckmaschine zu Problemen beim Produktionsstart durch Papierbahnrisse führen.Further disadvantages are that due to the necessary application of Detergent and water two detergents are used, each not efficient due to the degree of soiling of the blanket printing cylinders enough or a corresponding washing time is required do. Likewise the fact that after the Cleaning process, usually in the brush systems, the Blanket cylinder has not dried. This can ever according to the conditions in the rotary printing press to problems Lead through paper web breaks at the start of production.
Es besteht daher die Aufgabe, eine Gummituchwaschvorrichtung zu schaffen, welche die obengenannten Nachteile systembedingt nicht aufweist. .It is therefore the task of a blanket washing device create, which the above disadvantages inherent in the system does not have. ,
Die erfindungsgemäße Lösung dieser Aufgabe besteht bei der Gummituchwaschvorrichtung der eingangs erwähnten Art insbesondere darin, daß der Gummituchwaschapparat mehreren Gummituchdruckzylindern zugeordnet und dazu an Fahrschlitten lösbar befestigbar ist, welche Fahrschlitten auf den vor jeweils einem Gummituchdruckzylinder angeordneten Führungsschienen in Schienen-Längsrichtung verfahrbar sind, daß die Gummituchwaschvorrichtung eine Absaugeinrichtung zum Absaugen des vom Gummituchdruckzylinder verschmutzten Gemischs aus Druckfarbe und Reinigungsflüssigkeit hat und daß der Gummituchwaschapparat über wenigstens eine Versorgungsleitung mit einer gegenüber der Rotationsdruckmaschine separaten Versorgungseinheit verbunden ist.The solution to this problem according to the invention is in the blanket washing device of the type mentioned in particular in that the blanket washer has several blanket printing cylinders assigned and releasably attachable to the carriage is which carriage on each in front of a blanket cylinder arranged guide rails in the longitudinal direction of the rails are movable that the blanket washing device a suction device for suctioning the rubber blanket cylinder dirty mixture of printing ink and cleaning fluid has and that the blanket washer over at least one supply line with one opposite the Rotary printing press connected to separate supply unit is.
Die erfindungsgemäße Gummituchwaschvorrichtung weist einen Gummituchwaschapparat auf, der gleichzeitig mehreren Gummituchdruckzylindern zugeordnet ist. Dieser Gummituchwaschapparat ist im Vergleich zur Längserstreckung des Gummituchdruckzylinders derart ausgestaltet, daß der Gummituchwaschapparat über einen Fahrschlitten entlang der Schienen-Längsrichtung einer an der Rotationsdruckmaschine gehaltenen Führungsschiene verfahrbar ist. Mit dem an der Führungsschiene in Längsrichtung verfahrbaren Fahrschlitten ist der Gummituchwaschapparat nur lösbar verbunden, so daß er vom Fahrschlitten gelöst und auf den einem anderen Gummituchdruckzylinder zugeordneten Fahrschlitten aufgesetzt werden kann. Da somit die wesentlichen Bauteile der erfindungsgemäßen Gummituchwaschvorrichtung an mehreren Gummituchdruckzylindern eingesetzt werden können, kann der mit einer solchen Gummituchwaschvorrichtung verbundene Herstellungsaufwand verteilt und somit erheblich reduziert werden. Die vergleichsweise handliche Ausgestaltung des Gummituchwaschapparates erleichtert nicht nur den Transport und die Handhabung der erfindungsgemäßen Vorrichtung, vielmehr ist auch der entsprechende Gummituchdruckzylinder selbst leicht einsehbar und zugänglich. Da die erfindungsgemäße Gummituchwaschvorrichtung eine Absaugeinrichtung hat, läßt sich der Gummituchdruckzylinder auch zeitsparend reinigen und trocknen, ohne daß auf ein zeitraubendes Trocknen der Gummituchdruckzylinder gewartet werden müßte. Dabei ist der Gummituchwaschapparat über wenigstens eine Versorgungsleitung mit einer gegenüber der Rotationsdruckmaschine separaten Versorgungseinheit verbunden.The blanket washing device according to the invention has a blanket washing apparatus on the simultaneous multiple blanket printing cylinders assigned. This blanket washer is compared to the longitudinal extension of the blanket printing cylinder designed such that the blanket washer over a carriage along the longitudinal direction of one the guide rail held movable is. With the longitudinally movable on the guide rail The blanket washer can only be detached from the carriage connected so that he detached from the carriage and on the another carriage assigned to another blanket printing cylinder can be put on. Since the essential components of the Blanket washing device according to the invention on several blanket printing cylinders can be used with a Such blanket washing device associated manufacturing costs distributed and thus significantly reduced. The comparatively Handy design of the blanket washer not only facilitates the transport and handling of the device according to the invention, rather is the corresponding Blanket cylinder itself easily visible and accessible. Since the blanket washing device according to the invention has a suction device, the blanket cylinder also clean and dry in a time-saving manner without time-consuming drying of the blanket printing cylinders maintained should be. The blanket washer is over at least one supply line with one opposite the Rotary printing press connected to separate supply unit.
