Abstract

The re-usable lock is provided for a printhead ink supply container. The ink supply line from the printhead to the container is covered by a rubber elastic closure by a hollow needle (5). In the base of the container, two electrodes are fitted through as components of an ink end detector. A cover device (2) is provided for at least one electrode (142). This can be released irreversibly by inserting the needle once. An electrode is surrounded by a ring-shaped member. An electrode is fitted in a recess in the base (14). The edge of the recess extends beyond the electrode.

Description

Die Erfindung betrifft eine Wiederverwendbarkeitssperre für einen Behälter für die Tintenversorgung eines Tintendruckkopfes.The invention relates to a reusability lock for a container for the ink supply of an ink printhead.

Derartige Tintendruckköpfe werden sowohl in den üblichen Bürodruckern als auch in kleinen schnellen Druckern eingesetzt.
Letztere sind Bestandteil von modernen Maschinen zum Drucken von Adressen oder zur Produktbeschriftung und zukünftig auch zum Frankieren von Postgut.
Für die Druckköpfe soll die Funktion so gewährleistet sein, daß möglichst keine Druckpunktausfälle auftreten. Das ist nicht nur wegen der Druckbildqualität im allgemeinen von Bedeutung, sondern insbesondere für sicherheitstechnisch relevante Druckbilddaten, wie Wert, Datum und Maschinennummer bei Frankierabdruck wichtig. Um Druckpunktausfälle und Beschädigungen des Druckkopfes zu verhindern, ist unter anderem eine möglichst blasenfreie Versorgung des Tintendruckkopfes mit der für diesen zugelassenen Tinte unbedingt zu gewährleisten.
Es ist üblich, siehe DE 27 09 730 C2, die Tintenverbindungsleitung vom Tintendruckkopf zum Behälter für die Tintenversorgung - im weiteren Frischtintenbehälter - über eine Hohlnadel an den Behälter anzudocken, wobei dieser mit einem gummielastischen Verschluß versehen ist, der von der Hohlnadel durchstoßen wird. Damit werden sowohl ein Lufteintritt in die Tintenversorgungsleitung als auch ein ungewollter Tintenaustritt aus dem Behälter vermieden. Es ist bei diesem Andockprinzip aber möglich, daß durch nicht autorisierte Personen der teilweise oder ganz entleerte Frischtintenbehälter mit irgendeiner Tinte wieder aufgefüllt und in den Drucker eingesetzt wird.
Das kann zu Ausfällen oder sogar zu Beschädigungen des Tintendruckkopfes führen.Such ink printheads are used both in the usual office printers and in small, fast printers.
The latter are part of modern machines for printing addresses or for product labeling and in future also for franking mail.
For the printheads, the function should be guaranteed so that there are no pressure point failures. This is important not only because of the print image quality in general, but especially for security-relevant print image data such as value, date and machine number when franking. Around To prevent pressure point failures and damage to the printhead, it is imperative, among other things, to ensure that the ink printhead is supplied with the ink that is approved for it, as free of bubbles as possible.
It is common, see DE 27 09 730 C2, to dock the ink connection line from the ink print head to the container for the ink supply - in the further fresh ink container - via a hollow needle to the container, which is provided with a rubber-elastic closure which is pierced by the hollow needle. This prevents both air from entering the ink supply line and unwanted ink from the container. However, it is possible with this docking principle that the partially or completely empty fresh ink container is refilled with any ink and inserted into the printer by unauthorized persons.
This can lead to failures or even damage to the ink printhead.

Zur sicheren Tintenversorgung ist es wichtig, Tintenende zu erkennen und rechtzeitig zu signalisieren. Es ist eine Tintenendeerkennung bekannt, siehe DE 27 27 283 C2, bei der im Boden des Frischtintenbehälters zwei Elektroden durchgehend eingebracht sind und der Übergangswiderstand zwischen diesen Elektroden gemessen und ausgewertet wird. Die Elektroden sind in Mulden angeordnet, die in den Behälterboden eingeformt sind. Voraussetzung für den Einsatz einer derartigen Tintenendeerkennung ist die Verwendung einer elektrisch leitfähigen Tinte.To ensure reliable ink supply, it is important to recognize the end of ink and signal it in good time. Ink end detection is known, see DE 27 27 283 C2, in which two electrodes are continuously inserted in the bottom of the fresh ink container and the contact resistance between these electrodes is measured and evaluated. The electrodes are arranged in depressions which are molded into the bottom of the container. The use of an electrically conductive ink is a prerequisite for the use of such an ink end detection.

Zweck der Erfindung ist eine Erhöhung der Funktionssicherheit.The purpose of the invention is to increase functional reliability.

Der Erfindung liegt die Aufgabe zugrunde, unter Beibehaltung der eingangs beschriebenen Andockung des Frischtintenbehälters und einer Tintenendeerkennung mittels im letzteren angeordneter Elektroden, eine Wiederverwendbarkeitssperre zu entwickeln, die nur den Einsatz von vom Hersteller des Druckers vorgeschriebenen neuen Frischtintenbehältern zuläßt. Der Einsatz von bereits einmal im Betrieb genommenen und wieder nachgefüllten Frischtintenbehältern ist zu unterbinden.The invention has for its object to develop a reusability lock while maintaining the docking of the fresh ink container described above and an ink end detection by means of electrodes arranged in the latter, which only permits the use of new fresh ink containers prescribed by the manufacturer of the printer. The use of fresh ink containers that have already been put into operation and refilled must be prevented.

Erfindungsgemäß wird diese Aufgabe gemäß den Patentansprüchen gelöst.
Indem mittels der Hohlnadel für die Tintenandockung eine Abdeckvorrichtung für mindestens eine der Elektroden einmal unumkehrbar auslösbar ist, wird erreicht, daß für einen einmal angedockten Frischtintenbehälter nach dem Ziehen der Hohlnadel stets Tintenende signalisiert wird, unabhängig davon, wieviel Tinte tatsächlich in dem Behälter vorhanden ist.
Ein einmal abgedockter und erneut angedockter Frischtintenbehälter ist demzufolge nicht mehr für die Tintenversorgung einsetzbar, sondern wenn überhaupt, nur noch für die Tintenentsorgung als Alttintenbehälter.According to the invention, this object is achieved according to the patent claims.
By irreversibly triggering a covering device for at least one of the electrodes by means of the hollow needle for ink docking, it is achieved that for a fresh ink container which has been docked once the end of the ink is always signaled after the hollow needle has been pulled, regardless of how much ink is actually present in the container.
Once the fresh ink container has been undocked and redocked, it can no longer be used for ink supply, but if at all, only for ink disposal as an old ink container.

Die Erfindung wird nachstehend am Ausführungsbeispiel näher erläutert.

Zur Vereinfachung und zum besseren Verständnis ist die Zeichnung teilweise schematisiert ausgeführt.To simplify and for a better understanding, the drawing is partially schematic.

Gemäß Fig. 1 weist ein Frischtintenbehälter 1 in seiner Frontwand 11 eine Bohrung 111 auf, in die ein gummielastischer Verschluß 4 eingesetzt ist. Durch den gummielastischen Verschluß 4 ist eine Hohlnadel 5 gesteckt, die über eine Tintenverbindungsleitung 6 in nicht dargestellter Weise an einen Tintendruckkopf angeschlossen ist. Die Seitenwände 12 und die Rückwand 13 des Frischtintenbehälters sind als glatte Wände ohne Durchführungen ausgebildet. In den Boden 14 ist eine muldenförmige Vertiefung 143 eingearbeitet in deren Bereich die Hohlnadel 5 mündet. Die Hohlnadel 5 weist seitlich eine Tintenöffnung 51 auf. Außerhalb der Vertiefung 143 sind zur Frontwand 11 hin in den Boden 14 zwei Elektroden 142 eingepaßt, die von einer diese überragenden Wulst 141 umgeben sind.
Am Boden 14 ist in der Vertiefung 143 eine Abdeckvorrichtung 2 angeordnet. Die Abdeckvorrichtung 2 besteht im wesentlichen aus einer um eine Achse 22 drehbeweglich gelagerten Wippe 21, zwei Lagerböcken 23 für die Achse 22 und einem federnden Rasthaken 25 sowie einer Druckfeder 24, vergleiche auch Fig. 2.
Die Abdeckvorrichtung 2 ist am Boden 14 so angeordnet und im einzelnen so ausgebildet, daß diese teilweise im Steckbereich der Hohlnadel 5 liegt. Zu diesem Zweck dient ein Zahn 2122 an der Wippe 21.
In Fig. 2 sind Einzelheiten des Aufbaus und des Wirkungsablaufes dargestellt. Bevor die Hohlnadel 5 mit der Wippe 21 in Wirkverbindung tritt, ist diese mit einem ersten kurzen hakenförmigen Hebelarm 211 der Wippe 21 an den Rasthaken 25 arretiert, vergleiche Fig. 2a. Zu diesem Zweck sind sowohl der Rasthaken 25 mit einer Nase 251 als auch der kurze Hebelarm 211 mit einer Nase 2111 versehen. Der Rasthaken 25 ist elastisch in Richtung kurzer Hebelarm 211 gebogen, so daß beide Nasen 251, 2111 kraftschlüssig miteinander verhakt sind.
Der kurze Hebelarm 211 ist außerdem durch die Druckfeder 24 zum Boden 14 hin abgefedert und wird durch dieselbe nach oben gegen den Rasthaken 25 gedrückt. Auf diese Weise ist der Frischtintenbehälter 1 ausreichend gegen eine ungewollte Auslösung der Abdeckvorrichtung 2 gesichert.
Der andere zweite, etwas längere Hebelarm 212 ist so ausgebildet, daß eine Elektrode 142 und der Steckbereich der Hohlnadel 5 in dessen Schwenkbereich liegen. Zwecks sicherer Abdeckung der Elektrode 142 beziehungsweise der diese umgebenden Wulst 141 ist der Hebelarm 212 am Ende innenseitig mit einem entsprechend angepaßten Belag 2121 versehen. Im Steckbereich der Hohlnadel 5 ist an dem Hebelarm 212 ein Zahn 2122 angeformt, an dessen Frontfläche die gesteckte Hohlnadel 5 mit der Spitze 52 kraftschlüssig anliegt. Wenn die Hohlnadel 5 mit ihrer Spitze auf die Frontfläche des Zahns 2122 trifft, werden der lange Hebelarm 212 nach oben und der kurze Hebelarm entgegen der Federkraft der Druckfeder 24 nach unten gedrückt. Infolgedessen wird der Rasthaken 25 freigegeben und gelangt außerhalb des Schwenkbereichen des kurzen Hebelarms 211, vergleiche Fig. 2b. Damit ist die Abdeckvorrichtung 2 entsichert.
Gemäß dem Übersetzungsverhältnis zwischen den beiden Hebelarmen 211, 212 beziehungsweise dem Angriffspunkt der Druckfeder 24 und dem Ansatzpunkt des Zahns 2122 liegt der lange Hebelarm 212 mit dem Zahn 2122 kraftschlüssig an der Hohlnadel 5 an. Wird die Hohlnadel 5 herausgezogen, so wird die Wippe 21 durch die Druckfeder 24 um die Achse 22 so weit herumgeschwenkt, daß der Belag 2121 auf der Wulst 141 kraftschlüssig aufliegt und der Zahn 2122 unterhalb des Steckbereiches der Hohlnadel 5 liegt. Wenn die Hohlnadel 5 erneut gesteckt wird, verbleibt die Wippe 21 in der geschilderten Lage. Die elektrische Verbindung zwischen den beiden Elektroden 142 ist damit unterbrochen und wird ständig als Tintenende ausgewertet. Somit ist ein erneuter Druckbetrieb mit diesem Frischtintenbehälter nicht mehr möglich.1, a fresh ink container 1 has a bore 111 in its front wall 11, into which a rubber-elastic closure 4 is inserted. A hollow needle 5 is inserted through the rubber-elastic closure 4 and is connected to an ink print head via an ink connection line 6 in a manner not shown. The side walls 12 and the rear wall 13 of the fresh ink container are designed as smooth walls without feedthroughs. A trough-shaped depression 143 is worked into the bottom 14, in the area of which the hollow needle 5 opens. The hollow needle 5 has an ink opening 51 on the side. Outside the recess 143 are to the front wall 11 two electrodes 142 are fitted into the base 14, which are surrounded by a bead 141 projecting therefrom.
A cover device 2 is arranged on the bottom 14 in the depression 143. The covering device 2 essentially consists of a rocker 21 mounted rotatably about an axis 22, two bearing blocks 23 for the axis 22 and a resilient latching hook 25 and a compression spring 24, see also FIG. 2.
The covering device 2 is arranged on the bottom 14 and designed in such a way that it partially lies in the plug-in area of the hollow needle 5. A tooth 2122 on the rocker 21 is used for this purpose.
In Fig. 2 details of the structure and the sequence of effects are shown. Before the hollow needle 5 comes into operative connection with the rocker 21, the latter is locked to the latching hook 25 with a first short hook-shaped lever arm 211 of the rocker 21, cf. FIG. 2a. For this purpose, both the locking hook 25 are provided with a nose 251 and the short lever arm 211 with a nose 2111. The latching hook 25 is elastically bent in the direction of the short lever arm 211, so that both lugs 251, 2111 are non-positively hooked together.
The short lever arm 211 is also cushioned by the compression spring 24 towards the bottom 14 and is pressed by the same upwards against the locking hook 25. In this way, the fresh ink container 1 is adequately secured against unwanted triggering of the cover device 2.
The other second, somewhat longer lever arm 212 is designed such that an electrode 142 and the plug-in area of the hollow needle 5 lie in its swivel area. For the purpose of securely covering the electrode 142 or the bead 141 surrounding it, the lever arm 212 is provided on the inside with a correspondingly adapted covering 2121. In the plug-in area of the hollow needle 5, a tooth 2122 is integrally formed on the lever arm 212, on the front surface of which the inserted hollow needle 5 with the tip 52 abuts in a non-positive manner. When the hollow needle 5 hits the front surface of the tooth 2122 with its tip, the long lever arm 212 is pushed up and the short lever arm is pressed down against the spring force of the compression spring 24. As a result, the latch hook 25 is released and moves outside the swivel range of the short lever arm 211, see FIG. 2b. The cover device 2 is thus unlocked.
According to the gear ratio between the two lever arms 211, 212 or the point of application of the compression spring 24 and the starting point of the tooth 2122, the long lever arm 212 abuts the hollow needle 5 with the tooth 2122. If the hollow needle 5 is pulled out, the rocker 21 is pivoted about the axis 22 by the compression spring 24 to such an extent that the coating 2121 lies non-positively on the bead 141 and the tooth 2122 lies below the plug-in area of the hollow needle 5. If the hollow needle 5 is inserted again, the rocker 21 remains in the position described. The electrical connection between the two electrodes 142 is thus interrupted and is continuously evaluated as the ink end. This means that printing with this fresh ink container is no longer possible.
