Definitions

  • a device for refilling ink in a printhead of an ink-jet printer comprises two juxtaposed cylinders. One contains ink, the other a piston and acts as a suction pump when filling. From the cylinders are hollow needles, which are inserted into the container of the printhead. The tips of the hollow needles are protected by pins, which are pulled off before use.
  • the present invention has for its object to improve this device. This object is achieved by the feature combination of the claims.
  • EP-510 854A a container for liquids is described.
  • the container is closed at the top by a collar and a waistband.
  • a lid is screwed, on which a centric cylindrical-conical projection projects with a longitudinal bore downwards. This extension breaks through when screwing the lid the collar.
  • the longitudinal bore opens into a pin, in which it is flared.
  • the pin is conical outside.
  • the mouth of the syringe is inserted without needle into the conical bore.
  • an ampoule is docked to the conical outer surface of the pin.
  • the apparatus of Figures 1 and 2 comprises a cylinder 1 which is only a fractional, e.g. to less than half filled with ink 2.
  • a piston 3 with a piston rod 4 which has a handle head 5 at the free end.
  • a hollow needle 6 is attached with a sealing ring. 7
  • the print head 10 To refill the print head 10, first its nozzle openings 11 are sealed airtight with a sealing cap 12. Through an opening in the cover 13 of the print head 10, the hollow needle 6 is inserted until the sealing engagement of the sealing ring 7 on the cover 13. Subsequently, the piston 3 is pulled up into the position of FIG. In this case, part of the air in the print head 10 is sucked through the ink. When releasing the grip head 5, the ink 2 is now sucked into the print head 10 by the negative pressure prevailing therein. In order to facilitate the inflow of the ink 2, the cylinder 1 may have an air supply opening 8 adjacent to its upper end. Through this Air flows in as soon as the piston 3 has reached its upper end position shown in FIG.
  • the device described is considerably simpler than those according to the aforementioned DE-GM 295 02 908 and requires only a single opening in the lid 13 of the print head 10, which is usually present anyway. It has been found that by sucking the ink under vacuum into the foam body 32, it can be filled considerably more efficiently and a decrease in the filling capacity after several fillings can be avoided. This is attributed to the fact that the vacuum in the air-filled pores of the foam body 32 is sucked by the negative pressure.
  • FIGS. 3 to 6 differs principally from that according to FIGS. 1 and 2 in that, in the delivery state, a pin 20 is plugged onto the free end of the hollow needle 6, which is pierced by the cover 13 of the print head 10 when the hollow needle 6 is inserted ,
  • the pin 20 is centered in a coaxial with the opening 21 in the lid 13 arranged conical countersink 22.
  • This design ensures that the pin 20 does not have to be removed before inserting the needle 6!
  • no ink can spray from the needle 6 into the environment.
  • This embodiment is also suitable for filling the print head with pressure, ie where the piston 3 is not first pulled up, but pressed down. This assumes that the printhead is not airtight.
  • the pin 20 also serves as a stop when inserting the needle 6 so that it penetrates to the optimum height within the print head 10.
  • the device described is also suitable for filling other containers with liquid, e.g. in the medical field.
