Vorrichtung zum Durchmischen von Tinten- und Lacksuspensionen in Schreibsystemen. Device for mixing ink and lacquer suspensions in writing systems.
Die Erfindung betrifft eine Vorrichtung zur Verhinderung des Absetzens von Tinten- und Lacksuspensionen bei der Verarbeitung in Schreibsystemen, insbesondere in Ink-Jet-Schreibsystemen. The invention relates to a device for preventing the settling of ink and lacquer suspensions in the Processing in writing systems, especially in ink-jet writing systems.
Bei Schreibsystemen, die im wesentlichen mit Tinten- und Lacksuspensionen arbeiten, wird die Schreibflüssigkeit tröpfchenförmig aus einer oder aus mehreren Düsen eines vom Aufzeichnungsträger abgehobenen Schreibkopfes gegen einen normalerweise bewegten Aufzeichnungsträger gespritzt. Sie bildet dort ein rasterförmiges Zeichen. Ein solches Verfahren ist beispielsweise in der Siemens-Zeitschrift, Heft 4, April 1977, Seiten 219 bis 221 beschrieben. In einem Schreibwerk sind dabei eine Reihe von Düsen in einer Matrixform angeordnet. Jede dieser Düsen kann durch einen piezoelektrischen Wandler getrennt angesteuert werden.In writing systems that essentially work with ink and lacquer suspensions, the writing fluid in droplets from one or more nozzles of a write head lifted from the recording medium injected a normally moving recording medium. There it forms a grid-shaped symbol. A Such a method is described, for example, in Siemens-Zeitschrift, No. 4, April 1977, pages 219 to 221. A row of nozzles are arranged in a matrix form in a writing unit. Any of these nozzles can controlled separately by a piezoelectric transducer.
Die Anforderungen, die an die verwendete Tinte bzw. den Lack gestellt werden, sind vielfältig. Für eine sichere Funktion des Schreibsystems ist eine bestimmte Oberflächenspannung und Viskosität der Schreibflüssigkeit notwendig. Die Schreibflüssigkeit soll auf Normalpapier eine kontrastreiche Schrift ergeben, die wischfest, dokumenten- und lichtecht ist. Sie darf in den Düsenöffnungen nicht eintrocknen, soll aber auf dem Papier sofort wischfest sein. Den verwendeten Tinten und Lacken sind in der Regel Pigmente beigemischt. Dabei besteht die Gefahr,The requirements that are placed on the ink or varnish used are diverse. For a safe The function of the writing system is a certain surface tension and viscosity of the writing fluid necessary. The writing fluid should produce a high-contrast writing on normal paper, which is smudge-proof, document- and is lightfast. It must not dry out in the nozzle openings, but should be on the paper immediately be smudge-proof. Pigments are usually added to the inks and varnishes used. There is a risk of

Der Erfindung liegt die Aufgabe zugrunde, die eingangs beschriebene Vorrichtung zum Durchmischen von Tinten- und Lacksuspensionen zu konzipieren. Diese Aufgabe wird dadurch gelöst, daß ein oder mehrere Schwingquarze am Tintenvorratsbehälter und/oder an den Kapillaren sowie Schreibkanälen angebracht sind.The invention is based on the object of the initially described device for mixing ink and To design lacquer suspensions. This object is achieved in that one or more oscillating crystals on the ink reservoir and / or are attached to the capillaries and writing channels.
Bei dem in der Siemens-Zeitschrift beschriebenen Schreibwerk werden die Düsenkanäle konzentrisch von Wandlern umschlossen. Bei diesen Wandlern handelt es sich um Röhrchen aus Piezokeramik. Nach einer Weiterbildung der Erfindung wird bei derartigen Schreibwerken in den Schreibpausen die Energie an den Röhrchen aus Piezokeramik so weit abgesenkt, daß sie keine Tröpfchen mehr auslöst, aber zur Durchmischung der Flüssigkeit ausreicht.In the writing mechanism described in the Siemens magazine, the nozzle channels are concentrically enclosed by transducers. These transducers are small tubes made of piezoceramic. According to a further development of the invention in writing pauses of this type, the energy at the piezoceramic tubes is reduced to such an extent that that it no longer releases droplets, but is sufficient to mix the liquid.
Mit der Erfindung wird erreicht, daß die Pigmente in der Suspension verbleiben. Außerdem werden Farbstoffe, die sich nicht immer ganz auflösen, durch die Schwingungen allmählich vollständig in Lösung gebracht. Gleichzeitig besteht die Möglichkeit, den oder die Schwinger zur Füllstandsermittlung zu benutzen. Die Vorrichtung nach der Erfindung eignet sich auch vorzugsweise zum pulsweisen Betrieb, und zwar immer dann, wenn der Schreibkopf nicht in Betrieb ist (Schreibpause, Wagenrücklauf).With the invention it is achieved that the pigments remain in the suspension. Also, dyes that do not always dissolve completely, gradually brought into solution by the vibrations. Simultaneously it is possible to use the transducer or transducers to determine the level. The device according to the The invention is also preferably suitable for pulse-wise operation, always when the writing head is not is in operation (writing pause, carriage return).
Die Erfindung ist für alle Schreibsysteme verwendbar. Ein wesentlicher Vorteil besteht darin, daß es sich um eine miniaturisierte Bauweise ohne bewegte Teile handelt. Die Vorrichtung nach der Erfindung verhindert ein Absetzen des Farbstoffes im Schreibkopf und in den Düsen..Außerdem ermöglicht sie das Verarbeiten von pigmentierten Tinten und Lacken. Bei der Verwendung des Schwingers zur Füllstandsermittlung kann gleichzeitig eine Verbilligung desThe invention can be used for all writing systems. A major advantage is that it is a miniaturized construction with no moving parts. The device according to the invention prevents settling of the dye in the print head and in the nozzles. It also enables the processing of pigmented inks and varnishes. When using the oscillator to determine the level, the
