Abstract
Description
Die Erfindung betrifft ein Verfahren zur Entfernung von Schablonenbeschichtungen auf Siebdruckformen, insbesondere deren Schablonenträgern. Desweiteren bezieht sich die Erfindung auf eine Vorrichtung zur Durchführung dieses Verfahrens.The invention relates to a method for removing Stencil coatings on screen printing forms, in particular their template carriers. Furthermore, the Invention on a device for performing this Procedure.
Für den Sieb- und Filmdruck werden im Prinzip zwei verschiedene Druckformen verwendet. Für den Flachsiebdruck kommt eine ebene Siebdruckform zur Anwendung, bei der der Schablonenträger auf einen rechteckigen Siebdruckrahmen aufgespannt ist und im wesentlichen aus einer gewebten Gaze aus Kunststoff- oder Metallfäden besteht. Für den Rotationssiebdruck (Filmdruck) ist eine zylindrische Druckform vorgesehen, bei der sich der Schablonenträger als zylindrischer Mantel zwischen zwei Endringen erstreckt. Gewöhnlich wird der Schablonenträger bei Rotationsdruckformen galvanisch aus Nickel hergestellt.In principle, two different ones are used for screen and film printing Printing forms used. For flat screen printing a flat screen printing form is used, in which the Stencil holder on a rectangular screen printing frame is stretched and essentially of a woven Gauze consists of plastic or metal threads. For the Rotary screen printing (film printing) is a cylindrical one Printing form provided in which the stencil holder extends as a cylindrical jacket between two end rings. The stencil carrier is usually used in rotary printing forms galvanically made of nickel.
Um ein bestimmtes Druckbild zu erreichen, werden Teile des Schablonenträgers, die nicht drucken sollen, mittels einer als Sperrschicht wirkenden Schablonenbeschichtung versehen, so daß sich farbundurchlässige und farbdurchlässige Bereiche ergeben. Für die Herstellung der Schablonenbeschichtung gibt es verschiedene Verfahren.To achieve a certain print image, parts the stencil carrier, which should not print, by means of a stencil coating acting as a barrier layer provided so that there are opaque and translucent Areas result. For the production of the stencil coating there are different procedures.
In gewissen Abständen steht die Entfernung der Schablonenbeschichtung an, beispielsweise um die Siebdruckform für die Herstellung eines anderen Druckbildes herzurichten. Im allgemeinen werden hierfür immer noch chemische Mittel verwendet, und zwar insbesondere dann, wenn es sich um gehärtete Schablonenbeschichtungen handelt. In diesem Fall sind sehr starke Oxidationsmittel (Jodate oder Periodate, Manganperoxid, Osmiumtetraoxid, Selendioxid usw.) aufbauend auf Polyvinylalkohol- oder Celluloseschichten erforderlich. Bei Gelatineschichten werden Enzyme eingesetzt. Auf jeden Fall wird hierdurch das Abwasser stark in Mitleidenschaft gezogen, so daß das Abwasser in teuren Anlagen aufbereitet werden muß.The stencil coating is removed at certain intervals , for example around the screen printing form to prepare for the production of another printed image. Generally, chemical ones are still used for this Means used, especially when it are hardened stencil coatings. In In this case, very strong oxidizing agents (iodates or periodate, manganese peroxide, osmium tetraoxide, selenium dioxide etc.) based on polyvinyl alcohol or cellulose layers required. With gelatin layers Enzymes used. In any case, the wastewater badly affected, so the sewage must be processed in expensive plants.
In jüngerer Zeit sind Vorschläge gemacht worden, Schablonenbeschichtungen mit Hilfe von Wasserstrahlen mit teilweise sehr hohen Drücken zu entfernen (vgl. EP 0 391 491 A1; EP 0 641 649 A1). Dabei kann auf die Anwendung von chemischen Substanzen nur dann verzichtet werden, wenn besonders hohe Drücke angewendet werden. Die hierfür erforderlichen Vorrichtungen sind aufwendig und deshalb teuer. Außerdem müssen Vorkehrungen getroffen werden, damit die Siebdruckform nicht durch den Wasserstrahl beschädigt wird. Recently, proposals have been made for stencil coatings with the help of water jets with partial to remove very high pressures (cf. EP 0 391 491 A1; EP 0 641 649 A1). The application of chemical substances can only be dispensed with if particularly high pressures are used. The necessary for this Devices are expensive and therefore expensive. Precautions must also be taken to ensure that the screen printing form is not damaged by the water jet becomes.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren bereitzustellen, mit dem sich Siebdruckformen ohne den Einsatz von Chemikalien entschichten lassen, und bei dem der apparative Aufwand vergleichsweise gering ist. Eine weitere Aufgabe besteht darin, eine Vorrichtung zur Durchführung dieses Verfahrens vorzuschlagen.The invention has for its object a method to provide with the screen printing forms without the Let the use of chemicals be decoated, and at the the outlay on equipment is comparatively low. A another object is to provide a device for Propose implementation of this procedure.
Der erste Teil der Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Siebdruckform mit dem Schablonenträger in ein Flüssigkeitsbad eingetaucht und durch Einwirkung einer Ultraschalleinrichtung entschichtet wird. Grundgedanke der Erfindung ist also der Einsatz von Ultraschall in einem Flüssigkeits-, insbesondere Wasserbad, und zwar in der Weise, daß ein direkter Kontakt zwischen Ultraschalleinrichtung und Siebdruckform entsteht. Der Schablonenträger kann dann nicht mehr durch Mitschwingen ausweichen, so daß der volle Druck der Ultraschalleinrichtung übernommen wird. Dies führt zu einer Sprengung der Schablonenbeschichtung, wobei die Wirkung auch auf der Rückseite vorhanden ist. Sollte diese Wirkung nicht ausreichen, kann die Siebdruckform nach dem ersten Entschichtungsvorgang umgedreht und dann nochmals der Ultraschalleinwirkung ausgesetzt werden.The first part of the task is according to the invention solved that the screen printing form with the stencil holder in a liquid bath immersed and by the action of a Ultrasonic device is decoated. Basic idea the invention is the use of ultrasound in a liquid, especially water bath, in the way that direct contact between the ultrasound device and screen printing form is created. The template holder can then no longer avoid swinging along, so that the full pressure of the ultrasound device is taken over. This will cause the stencil coating to explode, the effect also on the back is available. If this effect is not sufficient, the screen printing form after the first stripping process turned over and then again the effect of ultrasound get abandoned.
Der Ultraschall besteht aus hochfrequenten Schallwellen mit Frequenzen über 16 kHz, die in der Flüssigkeit Dampf- oder Gasblasen entstehen lassen, die nach einer Expansionsphase implodieren. Hierdurch entstehen hohe Druckstöße und Turbulenzen und auch Hitzewellen, die bei Einwirkung auf den Schablonenträger bei entsprechender Intensität zu einer Entschichtung führt. Die Intensität der Ultraschalleinrichtung kann so eingestellt werden, daß hierdurch der Schablonenträger nicht angegriffen wird.The ultrasound consists of high-frequency sound waves with frequencies above 16 kHz which are vaporized in the liquid or create gas bubbles after an expansion phase implode. This creates high pressure surges and turbulence and also heat waves that when exposed towards the stencil holder with the appropriate intensity de-coating. The intensity of the ultrasound device can be set so that this the template carrier is not attacked.
Die Vorteile gegenüber den konventionellen Verfahren liegen darin, daß auf den Einsatz von Chemikalien vollständig verzichtet werden kann, d. h. alle damit verbundenen Nachteile, wie Verschmutzung, Luftemission, Brandgefahr, Verätzungsgefahr sowie das Vorhalten solcher Chemikalien fallen hier weg. Die abgelösten Schablonenbeschichtungen können durch einfaches Abfiltrieren oder Ausfällen aus dem wäßrigen Medium des Flüssigkeitsbades entfernt und deponiert werden, soweit sie nicht aufbereitet werden können. Es ergibt sich eine gründliche Reinigung selbst an den Fadenkreuzungen des Gewebes des Schablonenträgers, selbst wenn gehärtete Schablonenschichten vorhanden sind.The advantages over conventional methods are in that on the use of chemicals completely can be dispensed with, d. H. all related Disadvantages such as pollution, air emissions, fire risk, Risk of chemical burns and the provision of such chemicals fall away here. The detached stencil coatings can by simple filtering or precipitation removed the aqueous medium of the liquid bath and be deposited, unless they are processed can. Thorough cleaning itself results at the crosshairs of the fabric of the template carrier, even if there are hardened stencil layers.
Im Vergleich zu der Entfernung mit Hilfe von Wasserstrahlen ist der apparative Aufwand wesentlich geringer. Auch die anfallenden Flüssigkeitsmengen halten sich in Grenzen. So reicht für eine flache Siebdruckform ein Flüssigkeitsbad aus, bei dem die Siebdruckform gerade eben eintaucht.Compared to the distance using water jets the outlay on equipment is considerably less. Also the amount of liquid is limited. A liquid bath is sufficient for a flat screen printing form where the screen printing form is just dipping.
Zwar ist es aufgrund der JP-A-4-351594 bekannt, Metallmasken oder Siebmasken in einem Flüssigkeitsbad von Druckmaterial wie beispielsweise Lötpaste, dadurch zu reinigen, daß die Maske in ein Flüssisgkeitsbad eingetaucht und mittels einer Mechanik hin- und herbewegt wird sowie zusätzlich durch eine Ultraschalleinrichtung beaufschlagt wird. Ein solches Verfahren ist jedoch für die Entschichtung von Siebdruckformen, also die Entfernung der Schablonenbeschichtung, nicht geeignet.Although it is known from JP-A-4-351594, metal masks or screen masks in a liquid bath from Print material such as solder paste, too clean that the mask is immersed in a liquid bath and is moved back and forth by means of a mechanism and additionally acted upon by an ultrasound device becomes. However, such a procedure is for the Stripping of screen printing forms, i.e. the removal the stencil coating, not suitable.
Es kann zweckmäßig sein, daß die Ultraschalleinwirkung auf Teile des Schablonenträgers begrenzt wird und die Ultraschalleinrichtung und der Schablonenträger relativ und parallel zueinander bewegt werden. Auf diese Weise besteht die Möglichkeit, Bereiche des Schablonenträgers von der Ultraschalleinwirkung auszunehmen, damit dort vorhandene Schablonenklebstoffe oder Schablonenlacke nicht angegriffen werden.It may be appropriate for the ultrasound to act is limited to parts of the template carrier and the ultrasonic device and the template carrier relative and be moved parallel to each other. That way there is the possibility of areas of the template carrier to exclude the effect of ultrasound, so that existing there Stencil adhesives or stencil coatings not attacked become.
Eine Vorrichtung zur Durchführung des vorbeschriebenen Verfahrens ist erfindungsgemäß durch eine Flüssigkeitswanne zum Einsetzen einer Siebdruckschablone und durch eine Ultraschalleinrichtung zum Einschallen von Ultraschall in Richtung auf die Flüssigkeitswanne gekennzeichnet. Es wird deutlich, daß diese Vorrichtung relativ einfach aufgebaut und somit der apparative Aufwand gering ist.A device for performing the above The method is according to the invention through a liquid pan for inserting a screen printing stencil and through an ultrasound device for sonicating ultrasound marked towards the liquid pan. It is clear that this device is relatively simple built up and thus the expenditure on equipment is low is.
In Sonderheit ist vorgesehen, daß die Ultraschalleinrichtung derart in die Flüssigkeitswanne hineinragt, daß die Ultraschalleinrichtung bei gefüllter Flüssigkeitswanne in die Flüssigkeit eintaucht. Dabei ist es zweckmäßig, wenn die Ultraschalleinrichtung an eine in die Flüssigkeitswanne eingelegte Siebdruckform angelegt wird. Dies kann beispielsweise mit Hilfe einer Hubeinrichtung geschehen, über die der Abstand zur Siebdruckform bzw. zum Schablonenträger bis hin zur Anlage der Ultraschalleinrichtung einstellbar ist.In particular, it is provided that the ultrasound device protrudes into the liquid pan such that the Ultrasonic device with filled liquid tank in the liquid dips. It is useful if the ultrasonic device to a in the liquid pan inserted screen printing form is created. This can for example with the help of a lifting device, about the distance to the screen printing form or to the stencil holder to the installation of the ultrasound device is adjustable.
Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß die Ultraschalleinrichtung an einem Träger angeordnet ist, der in einer horizontalen Ebene verfahrbar ist, damit die gesamte Fläche des Schablonenträgers mit Ultraschall beaufschlagt werden kann. Konkret kann dies dadurch geschehen, daß der Träger als Trägerbrücke ausgebildet ist, welche beidseits im Randbereich der Flüssigkeitswanne verfahrbar geführt ist, wobei die Trägerbrücke zweckmäßigerweise in einer Richtung verfahrbar ausgebildet und die Ultraschalleinrichtung quer dazu relativ zu dem Träger verfahrbar aufgehängt ist.According to a further feature of the invention, that the ultrasound device is arranged on a support is that is movable in a horizontal plane, so the entire surface of the template carrier with ultrasound can be applied. This can be done in concrete terms happen that the carrier is designed as a girder bridge which is on both sides in the edge area of the liquid pan is guided, the support bridge expediently designed to be movable in one direction and the ultrasound device transverse to it relative to the carrier is suspended.
Zur Beschleunigung der Entschichtung kann es vorteilhaft sein, wenn die Ultraschalleinrichtung mehrere Ultraschallerzeuger, auch Sonotroden genannt, aufweist.It can be advantageous to accelerate the stripping be if the ultrasound device has several ultrasound generators, also called sonotrodes.
Zum Auffangen der abgelösten Beschichtungsteilchen sollte in dem Abfluß der Flüssigkeitswanne eine Filtereinrichtung vorgesehen sein.To catch the detached coating particles should a filter device in the drain of the liquid pan be provided.
