DruckvorrichtungPrinting device

Die Erfindung betrifft eine Druckvorrichtung für ein durch Ausspritzen von Farbe erfolgendes Herstellen von Zeichen, Symbolen und dergleichen mit einer Pumpe zum Fördern der Farbe.The invention relates to a printing device for a by ejection of Color making of characters, symbols and the like with a pump to deliver the paint.

Es ist ein vorzugsweise für Elektrokardiographen verwendbarer Strahlschreiber bekannt, der eine Pumpe zum Fördern der Schreibflüssigkeit aufweist. Als Pumpe dienen zwei im Gegentakt arbeitende Kolbenpumpen mit kraftschlüssig verbundenen Kolben. Die Pumpenkolben werden von einem Nocken über jeweils einen Backen einer Zange betätigt. Zur Pumpe gehört eine Ventilanordnung mit Einlaß- und Auslaßventilen, die sämtlich in einem besonderen Ventilgehäuse untergebracht sind. In dem Ventilgehäuse wird eine Trennung der Schreibflüssigkeit von der Arbeitsflüssigkeit der Doppelpumpe vorgenommen. Als Arbeitsflüssigkeit dient öl. Die Notwendigkeit einer Arbeitsflüssigkeit zusätzlich zur Schreibflüssigkeit ruft besondere Dichtungeprobleme und einen erhöhten konstruktiven Aufwand hervor, wodurch die Funktionssicherheit nicht günstig beeinflußt wird. Außerdem ist die Massenträgheit der massereichen Einstellteile für die beiden Kolbenpumpen und die Doppelkolben jederIt is a beam recorder that can preferably be used for electrocardiographs known, which has a pump for conveying the writing fluid. Two push-pull piston pumps with non-positively connected pistons serve as the pump. The pump pistons are driven by a cam operated by one jaw each of a pair of pliers. A valve assembly is part of the pump with inlet and outlet valves, all of which are housed in a special valve housing. There is a separation in the valve housing the writing fluid made by the working fluid of the double pump. Oil is used as the working fluid. The need for a working fluid In addition to the writing fluid, it causes special sealing problems and an increased design effort, which increases the functional reliability is not favorably influenced. In addition, the inertia of the massive adjustment parts for the two piston pumps and the double pistons each

dieser Kolbenpumpen ziemlich groß, so daß die Ansprechzeit des Schreibers ziemlich lang ist.these piston pumps quite large, so that the response time of the recorder is quite long.

Nachteile dieses bekannten Strahlschreibera vermeidet die Erfindung dadurch, daß in einem Zylinder eine durch die Kraft einer Feder gegen die Mündungsöffnung eines mit dem Farbbehälter verbundenen Rohres gedrückte Kugel aus ferromagnetischem Material mit etwas geringerem Durchmesser als der Zylinderinnendurchmesser angeordnet ist, daß der Zylindermantel eine Wicklung aufnimmt und die andere Zylinder Stirnseite Öffnungen größeren Querschnittes als der Ringspalt zwischen Kugel und Zylinder aufweist, die in einen der Düsenöffnung vorgelagerten Hohlraum münden und daß die Federkonstante, der Federweg und die Windungen der Wicklung so aufeinander abgestimmt sind, daß die Kugel mit großer Geschwindigkeit von denn mit dem Farbbehälter verbundenen Rohr weg und mit kleinerer Geschwindigkeit gegen dasselbe bewegbar ist. Demzufolge besitzt die erfindungsgemäße Pumpe einen wesentlich einfacheren Aufbau und ist masseärmer als der bekannte Strahlschreiber, so daß eine gegenüber demselben wesentlich kürzere Ansprechzeit erzielbar ist, wodurch selbst bei einem Druckvorgang mit sehr hoher Geschwindigkeit ein sauberes Druckbild erzielbar ist. Die Nichtnotwendigkeit zweier voneinander getrennt zu haltender Flüssigkeiten wirkt sich hierbei besonders vorteilhaft aus, da reibungserzeugende Trennelemente entbehrlich sind und insgesamt die Anzahl der bewegbaren Teile vermindert ist.The invention avoids disadvantages of this known jet pen in that that in a cylinder one pressed by the force of a spring against the mouth of a tube connected to the paint container Ball made of ferromagnetic material with a slightly smaller diameter than the inner diameter of the cylinder is arranged that the cylinder jacket accommodates a winding and the other cylinder face has openings with a larger cross-section than the annular gap between the ball and the cylinder, which open into a cavity upstream of the nozzle opening and that the spring constant, the spring deflection and the turns of the winding are as follows are coordinated that the ball at high speed away from the pipe connected to the paint container and at a lower speed is movable against the same. Accordingly, the invention has Pump has a much simpler structure and is lower in mass than the known jet pen, so that one opposite the same significantly shorter response time can be achieved, whereby a clean print image can be achieved even when printing at a very high speed is. The lack of need for two liquids to be kept separate from one another has a particularly advantageous effect because they generate friction Separating elements are unnecessary and the number of movable parts is reduced overall.

Der Zylinder 2, der aus verschiedenen Teilen bestehen kann, weist das Rohr 9 auf, das mit seinem freien Ende in den durch das Rohr 11 auf Außendruck gehaltenen Druckfarbbehälter 10 eintaucht. Die Kugel 1 kann in dem Zylinder 2 aus ihrer Lage 1' durch die Schraubenfeder 3 in ihre Ruhelage 2' bewegt werden, in welcher sie das Rohr 9 verschließt. Der in den Zylinder 2 eingeschraubte Teil 7 besteht aus Weicheisen und wirkt als Magnetkern für die Spule 4, als Anschlag für die Kugel 1 und als Träger für die Schraubenfeder 3. Der Teil 7 füllt den Zylinder 2 nicht völlig aus, sondern besitzt zwei abgeflachte Seiten (Fig. la). Dadurch entstehen die Zwischenräume 6, die den Hohlraum 5 der Düse 8 mit dem Zylinderteil 2' , in dem die Kugel 1 sich in ihrer Ruhelage 2* befindet. Wird die Wicklung 4 erregt, entsteht ein magnetisches Feld, das die aus ferromagnetischem Material kleiner Remanenz bestehende Kugel 1 bewegt. Bei dieser Bewegung der Kugel 1, die am Anschlag 7 endet, wird die Schraubenfeder 3 zusammengedrückt. The cylinder 2, which can consist of different parts, has the tube 9, the free end of which is immersed in the printing ink container 10 held at external pressure by the tube 11. The ball 1 can be moved in the cylinder 2 from its position 1 'by the helical spring 3 into its rest position 2', in which it closes the tube 9. The part 7 screwed into the cylinder 2 consists of soft iron and acts as a magnetic core for the coil 4, as a stop for the ball 1 and as a support for the helical spring 3. The part 7 does not completely fill the cylinder 2, but has two flattened sides (Fig. La). This creates the intermediate spaces 6, which form the cavity 5 of the nozzle 8 with the cylinder part 2 ' , in which the ball 1 is in its rest position 2 *. If the winding 4 is excited, a magnetic field is created which moves the ball 1 made of ferromagnetic material with a small remanence. During this movement of the ball 1, which ends at the stop 7, the helical spring 3 is compressed.

Das erzeugte magnetische Feld ist so stark, daß trotz des Zusammendrükkens der Schraubenfeder 3 die Kugel sehr schnell in Richtung auf den Teil 7 bewegt wird.The generated magnetic field is so strong that despite the compression the coil spring 3, the ball is moved very quickly in the direction of the part 7.

Der Durchmesser der Kugel ist etwas kleiner als der Innendurchmesser des Zylinders, wodurch der Ringspalt 2" zwischen der Kugel und der Zylinder innenwandung entsteht. Da die Verschiebung der Kugel sehr schnell erfolgt, kann*die zwischen der Kugel 1 und dem Teil 7 befindliche Druckfarbe nur verwirbelt und mit kleiner Menge durch den Ringspalt 2" fließen. Die Farbe wird dann durch die größeren Zwischenräume 6 in den Hohlraum 5 ausgestoßen, dessen Inhalt wiederum durch die Düse 8 gedrückt wird. Bei dieser sehr schnellen Bewegung gegen den Teil 7 öffnet die Kugel 1 die Öffnung des Rohres 9» wodurch ein Unterdruck entsteht, der Druckfarbe aus dem Behälter 10 ansaugt. Diese Farbe füllt während der Bewegung der Kugel 1 gegen den Teil 7 den Raum, den die Kugel 1 in ihrer Ruhelage 2* einnimmt. 9 0 9 8 4 3 /0 0 6 3The diameter of the sphere is slightly smaller than the inner diameter of the cylinder, creating the 2 "annular gap between the ball and the cylinder inner wall is created. Because the displacement of the ball very quickly occurs, the printing ink located between the ball 1 and the part 7 can * only flow swirled and with a small amount through the annular gap 2 ". The paint is then ejected through the larger spaces 6 into the cavity 5, the contents of which are in turn pushed through the nozzle 8. at This very rapid movement against the part 7 opens the ball 1 the opening of the tube 9, whereby a negative pressure arises, the printing ink from the container 10 sucks. During the movement of ball 1 towards part 7, this color fills the space that ball 1 in its rest position 2 * occupies. 9 0 9 8 4 3/0 0 6 3

Wenn die Wicklung 4 stromlos wird, kehrt die Kugel durch die Wirkung der Feder 3 in ihre Ruhelage zurück. Diese Bewegung erfolgt weniger schnell, so daß in dem, von der Kugel 1 in ihrer Ruhelage 2' eingenommenen Raum kein Unterdruck erzeugt wird und die in diesem Raum befindliche Farbe durch den Ringspalt 2" wirbelfrei hindurchfließen kann. Wenn die Rückbewegung der Kugel beendet ist, wird das Rohr 9 wieder verschlossen, und die im Zylinder 2" befindliche Farbe ist dann bereit für ein Aus-• stoßen in den Hohlraum 5 während der nächsten Arbeitsbewegung der Kugel 1.When the winding 4 is de-energized, the ball returns through the action the spring 3 back to its rest position. This movement occurs less quickly, so that no negative pressure is generated in the space occupied by the ball 1 in its rest position 2 ', and that which is in this space Color can flow through the annular gap 2 "without vortices. If the return movement of the ball has ended, the tube 9 is closed again, and the paint in the cylinder 2 "is then ready to be switched off. bump into the cavity 5 during the next working movement of the ball 1.

Es sind Farben verschiedener Viskosität verwendbar, jedoch müssen die Durchmesser der Kugel und des Zylinders als auch die Feder spannung entsprechend abgeändert werden. Das Ende derJDüse 8 geht in einen rohrförmigen Ansatz über, wodurch mehrere derartige Vorrichtungen auf einem begrenzten Raum anordenbar sind. So ist es möglich, durch entsprechende zeitliche Steuerung mehrerer derartiger Vorrichtungen eine Druckma- **" trix zu bilden, welcljpraus Punkten zusammengesetzte unterschiedliche Zeichen herstellen kann. Sind hierbei die Einzelpunkte nahe genug angeordnet, wird der Eindruck einer ununterbrochenen Linie erweckt.Inks of different viscosities can be used, but they must The diameter of the ball and the cylinder as well as the spring tension can be changed accordingly. The end of the nozzle 8 goes into a tubular one Approach over, whereby several such devices can be arranged in a limited space. It is thus possible, by appropriate time control of several such devices, to print a ** " trix to form welcljpraus composed of different points Can make characters. If the individual points are arranged close enough, the impression of an uninterrupted line is created.

Es ist sogar möglich, durch Verwendung unterschiedlicher Druckfarben in den einzelnen Vorrichtungen einen Mehrfarbendruck zu erzeugen.It is even possible by using different inks to produce a multicolor print in the individual devices.
