Definitions

  • the invention relates to a reusability lock for a container for the ink supply of an ink printhead.
  • 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.
  • 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.
  • security-relevant print image data such as value, date and machine number when franking.
  • 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.
  • the purpose of the invention is to increase functional reliability.
  • 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.
  • this object is achieved according to the patent claims.
  • 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.
  • 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.
  • 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.
  • the lever arm 212 is provided on the inside with a correspondingly adapted covering 2121.
  • 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.
  • 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.
