Description
Die Erfindung betrifft ein Verfahren zur Reinigung der Siebschablone einer Siebdruckeinrichtung, bei dem eine Papierbahn für einen Zwischendruck unter die Siebschablone gebracht und durch eine über diese laufende Rakel bedruckt wird. Die Erfindung betrifft auch eine Siebdruckmaschine zur Durchführung dieses Verfahrens.The invention relates to a method for cleaning the screen stencil of a screen printing device, in which a paper web for an intermediate pressure is placed under the screen template and printed by a doctor blade running over it. The invention also relates to a screen printing machine for carrying out this method.
Ein Reinigungsverfahren und eine zur Durchführung des Reinigungsverfahrens geeignete Siebdruckmaschine ist aus der
Maschinen dieser Art arbeiten zufriedenstellend, können aber den Nachteil nicht verhindern, dass die Siebdruckfarbe zum Teil eintrocknet und das Siebgewebe verstopft. Es ist daher bei Siebdruckeinrichtungen trotz der Anordnung eines zur Siebreinigung verwendeten Zwischendrucktisches notwendig, die Produktion anzuhalten, um das Sieb zu reinigen.Machines of this type work satisfactorily, but can not prevent the disadvantage that the screen printing ink dries in part and clogs the screen cloth. It is therefore necessary in screen printing devices, despite the arrangement of an intermediate printing table used for screen cleaning, to stop production in order to clean the screen.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine solche Reinigung weitgehend automatisch vorzunehmen und zwar, um einen Produktionsausfall zu vermeiden, während des Betriebes. Gleichzeitig damit sollen bessere Arbeitsbedingungen geschaffen und eine Fehlproduktion vermieden werden.The present invention has for its object to perform such a cleaning largely automatically and indeed to avoid production loss during operation. At the same time, it aims to create better working conditions and avoid mis-production.
Zur Lösung dieser Aufgabe wird bei einem Verfahren der eingangs genannten Art vorgesehen, dass vor der Ausführung des Zwischendruckes die Unterseite der Siebschablone mit einem Reinigungsmittel benetzt wird. Durch diese Maßnahme werden auch Farbreste vom Sieb gelöst, die schon eingetrocknet sind und daher durch die Maßnahme eines Zwischendruckes, der durch die Bewegung des Rakelwerkes auf ein Zwischendruckpapier erfolgt, das dann aufgerollt und entfernt wird, nicht von der Siebschablone entfernt hätten werden können.To achieve this object, it is provided in a method of the type mentioned that before the execution of the intermediate pressure, the underside of the screen stencil is wetted with a detergent. By this measure, paint residues are also released from the sieve, which are already dried and therefore by the measure of an intermediate pressure, which takes place by the movement of the squeegee on an intermediate printing paper, which is then rolled up and removed, could not have been removed from the screen template.
In weiterer Ausgestaltung des erfindungsgemäßen Verfahrens erfolgt das Benetzen durch eine in Kontakt mit der Unterseite der Siebschablone gebrachte rotierende Walze oder Bürste, die in ein Reinigungsmittel eintaucht. Durch die Rotation der Walze oder Bürste wird das Reinigungsmittel aus dem Bad herausgefördert und an die Unterseite der Siebschablone gebracht, wo es angetrocknete Farbreste lösen kann, die dann beim Zwischendruck entfernbar sind.In a further embodiment of the method according to the invention, the wetting is carried out by a placed in contact with the underside of the screen template rotating roller or brush, which dips into a cleaning agent. The rotation of the roller or brush, the detergent is conveyed out of the bath and brought to the bottom of the screen template, where it can dissolve dried paint residues, which are then removable at intermediate pressure.
Die Erfindung betrifft auch eine Siebdruckmaschine zur Durchführung des Reinigungsverfahrens, wobei die Siebdruckmaschine mit einer Zwischendruckeinrichtung, mit der eine Papierbahn unter die Siebschablone zum Zweck der Reinigung einführbar ist, ausgerüstet ist. Die neue Siebdruckmaschine ist gekennzeichnet durch eine der Zwischendruckeinrichtung zugeordnete und quer zur Bewegungsrichtung der Zwischendruckenrichtung angeordneten Rotationskörper, der mit einem Reinigungsmittel beschichtbar ist und vor dem Zwischendruck in Kontakt mit der Unterseite der Siebschablone kommt und an dieser entlangführbar ist.The invention also relates to a screen printing machine for carrying out the cleaning method, wherein the screen printing machine is equipped with an intermediate printing device with which a paper web is inserted under the screen template for the purpose of cleaning. The new screen printing machine is characterized by one of the intermediate pressure device associated and arranged transversely to the direction of the intermediate pressure direction of rotation body, which is coatable with a detergent and comes before the intermediate pressure in contact with the underside of the Siebschablone and can be guided along this.
Durch diese Ausgestaltung kann die Reinigung selbsttätig und in der Siebdruckmaschine vorgenommen werden.By this configuration, the cleaning can be done automatically and in the screen printing machine.
In Ausgestaltung der Erfindung kann als Rotationskörper eine Walze vorgesehen werden, die in ein Bad des Reinigungsmittels eintaucht. Dieses Reinigungsmittel kann in Weiterbildung der Erfindung in einem die Walze unten umfassenden und der Form der Walze angepassten Behälter enthalten sein, wobei die Oberfläche der Walze aufgeraut ausgebildet wird, um eine ausreichend dicke Schicht des Reinigungsmittels zu halten und gegen die Siebschablone bringen zu können.In an embodiment of the invention can be provided as a rotating body, a roller which dips into a bath of the detergent. This cleaning agent may be contained in a further development of the invention in a roll comprising the bottom and adapted to the shape of the roll container, wherein the surface of the roll is formed roughened to hold a sufficiently thick layer of the detergent and to bring against the Siebschablone.
In Weiterbildung der Erfindung ist die Walze rotierend angetrieben, und sie greift zu diesem Zweck mit seitlich angeordneten Ritzeln in eine Zahnstange ein, die neben der Siebschablone am Druckwerk angeordnet ist.In a further development of the invention, the roller is driven in rotation, and it engages for this purpose with laterally arranged pinions in a rack, which is arranged next to the screen template on the printing unit.
Die Zwischendruckeinrichtung selbst ist absenkbar und anhebbar und damit an- und abklappbar ausgebildet, wobei eine Steuereinrichtung zur Bestimmung des Reinigungszyklus vorgesehen sein kann, so dass beispielsweise nach jedem zweiten, dritten oder fünften Druck ein Reinigungsdruckvorgang vorgenommen wird.The intermediate pressure device itself can be lowered and raised and thus formed and folded down, wherein a control device may be provided for determining the cleaning cycle, so that, for example, after every second, third or fifth printing, a cleaning printing operation is performed.
In vorteilhafter Weiterbildung ist die Walze und der ihr zugeordnete Behälter, dem das Reinigungsmittel in einfacher Weise im Kreislauf zugeführt wird, an dem der Siebschablone zugewandten Ende einer in Richtung der Rakelbewegung verschiebbar gelagerten Papier-Gegendruckwalze angeordnet.In an advantageous development, the roller and its associated container, to which the cleaning agent is supplied in a simple manner in the circuit, arranged at the screen stencil facing the end of a slidably mounted in the direction of blade movement paper counter-pressure roller.
Um die Möglichkeit des Anhebens und Absenkens für die Reinigungsmittelwalze zu verwirklichen, kann die Walze mit dem Behälter zweckmäßig auf einem Schwenkhebelpaar angeordnet sein, das von pneumatischen Zylindern so beaufschlagbar, dass die seitlichen Ritzel der Walze in die Zahnstange eingreifen, die fest neben der Siebschablone verläuft. In an sich bekannter Weise kann schließlich die Zwischendruckwalze mit Papier versehen und mindestens um die Länge der Siebschablone verfahrbar angeordnet werden, so dass vor dem Zwischendruck die gesamte Unterseite der Siebschablone mit einem Reinigungsmittel benetzbar ist. In der Praxis genügt die Benetzung im Druckbereich.In order to realize the possibility of raising and lowering of the detergent roller, the roller with the container may be conveniently arranged on a pair of pivot levers which acted upon by pneumatic cylinders so that the lateral pinion of the roller engage in the rack, which runs fixed next to the Siebschablone , In known manner, finally, the intermediate pressure roller can be provided with paper and arranged to be movable at least by the length of the screen template, so that before the intermediate pressure, the entire bottom of the screen template with a cleaning agent is wettable. In practice, the wetting in the pressure range is sufficient.
Anstelle der Zwischendruckwalze mit einer sich abwickelnden Papierbahn kann auch ein endloses Bandmaterial zur Aufnahme des Zwischendruckes vorgesehen sein, oder auch eine Druckträgerwalze. In beiden Varianten kann für eine kontinuierliche Reinigung der Endlosbahn oder der Druckträgerwalze gesorgt werden. Verbrauchsmaterial in der Form von Papier fällt dann nicht an.Instead of the intermediate pressure roller with a unwound paper web can also be an endless strip material for receiving the intermediate pressure may be provided, or even a print carrier roll. In both variants, a continuous cleaning of the endless web or the print carrier roll can be ensured. Consumables in the form of paper then do not accrue.
