Definitions

  • the present invention relates to an apparatus for refilling an ink cartridge for an ink jet printer according to the preamble of claim 1, and a corresponding method.
  • cartridges with integrated printheads on the one hand and cartridges with an ink outlet opening which can be coupled to the ink supply of an ink jet head.
  • the aforementioned printheads include a plurality of very fine jet nozzles through which the ink is transferred to a print carrier.
  • a so-called wick is usually arranged in the latter and in fluid communication with an ink reservoir arranged inside the ink cartridge and consisting of absorbent material.
  • the aforementioned nozzles are directly in fluid communication with the ink reservoir disposed within the cartridge.
  • the ink reservoir is made either of fibrous material or of a foam. Since this is a known measure in this respect, a more detailed description of the same is unnecessary here.
  • Cartridges with integrated printheads must be broken up or resealed very carefully to refill with ink. The effort is correspondingly large and not profitable for cartridges with small quantities.
  • syringe refill systems are known for cartridges of the aforementioned type, by means of which an original cartridge can be refilled.
  • the respective sets include a drill, a hot glue gun, at least four syringes with cannula, ink, a conventional rubber band and closure.
  • the aforementioned systems are commercially available. However, they are characterized by unwieldiness and disproportionate effort in terms of material and tools.
  • Cartridges with an integrated printhead are in practice bought very expensive on the so-called “recycling market.” They are then mechanically opened, cleaned and provided with a new ink reservoir, eg sponge or the like All this work can only be done by a special refill company, not by the user himself.
  • the Applicant has already proposed an improvement for refilling ink cartridges for an ink jet printer, namely in PCT / EP2007 / 009808, such that an ink filled container is provided having an opening in which one enters the ink immersed and with the ink reservoir of the ink cartridge can be brought into contact capillary element is, for example like a wick.
  • the refilling of the ink cartridge thus takes place through the Tintenauslenfinö réelle or the ink nozzles.
  • the present invention is based on the object, one outside of a
  • printers usable device for refilling an ink cartridge for an ink jet printer which is easy to manufacture and in particular easy to handle, so that it can be easily controlled by the end user. It should also be equally effective for cartridges with integrated print heads as well as cartridges with an ink outlet opening which can be coupled to the ink supply of an ink jet head.
  • a reasonable refilling time is about 15 to 30 minutes with a refilling amount of 6 to 15 gr.
  • An essential aspect of the present invention thus resides in a separate receiving device for the ink cartridge to be refilled on the one hand and an ink refilling container on the other hand, wherein either the ink cartridge or the ink refilling container or both can be positioned within the receiving device so that the connecting element for transferring the ink from the Tintennach Stahl- container in the ink reservoir of the ink cartridge at or alternatively through an opening therethrough with the ink reservoir in fluid contact can be brought. It is therefore a separate, usable outside the printer device for refilling an ink cartridge. When doing so, use the vent opening in the ink cartridge, if possible, to gain access to it To get ink storage inside the ink cartridge.
  • the assignment of ink cartridge and Tintennach Stahlllb e humiliater within the common recording device can be done in many ways.
  • the ink cartridge, the Tintennach Stahler or both are slidably mounted within the receiving device, so that they are movable towards each other for filling the ink cartridge and after filling away from each other.
  • Tintennach Stahlixer has at least one, in particular two latching hooks by means of which the ink cartridge during its filling with the Tintennach Stahlixer is lockable such that both containers a fixed or immovable Define building unit. This ensures that the refilling takes place essentially without danger of leaks or other such contamination.
  • the connector associated with the ink refill container is either a capillary element, e.g. EP 0 536 980 B1, or a capillary needle, wherein the capillarity of the connecting element is slightly smaller than the capillarity of the ink reservoir in the ink cartridge
  • Capillary connection must therefore always be slightly smaller than the absorbency of the ink reservoir, to ensure a Nachsaugen of ink in the ink reservoir.
  • the suction effect must preferably always be so great that the static pressure of the liquid column in the ink reservoir is overcome, it being based in this regard about 1 mbar per cm liquid column.
  • capillary needles with a diameter of 0.05 to 1.5 mm, in particular of 0.1 to 1.0 mm are well suited.
  • a capillary needle instead of a capillary needle, a wick, sponge, a tube filled with a corresponding material or the like can also be used as a connecting element.
  • a sealing element around the connecting element, which ensures a fluid seal against the external environment during the refilling of the ink cartridge, ie when the ink cartridge and ink refilling container for the purpose of refilling the ink cartridge are locked together.
  • the mentioned sealing element thus lies around the connecting element between ink cartridge and Tintennach Stahl orer, preferably under a slight axial pressure, so that the above-mentioned sealing effect against the external environment is ensured.
  • the wall of the ink Vietnamese spallyogll mattersers is at least partially formed so thin or resilient that it can be pressed for the purpose of building increased pressure within the Tintennach spall mattersers, for example, between index finger and thumb.
  • the receiving device has a shaft accessible in particular from above for receiving and positioning an ink cartridge to be replenished and a guide receptacle for the ink refilling container extending transversely thereto.
  • the ink refilling container preferably together with the connecting element, is mounted so that it can be displaced back and forth along the guide receptacle extending transversely to the ink cartridge receiving shaft.
  • the ink cartridge and the ink refilling container are interlocked with each other for the purpose of refilling the ink cartridge.
  • This locking occurs outside of a printer at any location where refilling of the ink cartridge is to occur. It ensures a safe and leak-free and clean refilling of the ink cartridge within a relatively short time, and it is also conceivable to put the receiving device during refilling on a pad so that the Tintennachglall capableer is above the ink cartridge or the ink storage of the same. The resulting increased static pressure accelerates refilling.

  • FIG. 2 shows the receiving device according to FIG. 1 with positioned ink cartridge and coupled ink refilling container, likewise in a perspective view;
  • Fig. 3 shows the arrangement of Figure 2 in longitudinal section.
  • the apparatus shown schematically in FIGS. 1 to 3 for refilling an ink cartridge 10 for an ink jet printer, not shown here, comprises a separate receptacle 11 for the ink cartridge 10 to be refilled and an ink refill receptacle 12 also located inside the receptacle 11, and FIG Although back in the direction of the double arrow 13 in Fig. 1 and herverschiebbar.
  • the Tintennach Valll matterer 12 is reciprocally mounted within the receiving device 11 and thus according to FIG. 2 can be coupled to the householdzufe Jewishde ink cartridge 10 and after filling of this again decoupled.
  • the ink cartridge 10 comprises an in Fig. 3 only indicated ink reservoir 14, which is made for example of absorbent material.
  • This ink reservoir 14 can be brought into fluid communication via a ventilation opening B in the ink cartridge 10 or in the housing thereof with a connecting element 16 in the form of a capillary needle.
  • Ink is introduced from the separate Tintennachhell orer 12 into the ink reservoir 14 via this capillary needle.
  • the ink refilling container 12 is shifted from the left end position shown in Fig. 1 in the illustrated in Figures 2 and 3 right end position within the receiving device 11 to the ink cartridge 10 out.
  • the capillary needle 16 is moved into the ink reservoir 14 through the ventilation opening 15.
  • the slightly higher suction force of the ink reservoir 14 causes ink to be sucked into the ink reservoir 14 from the ink refilling container 12 through the capillary needle 16, until the ink reservoir 14 is saturated with ink or substantially completely refilled.
  • the ink refilling container 12 is reciprocated within a transverse shaft of the receiving device in the direction of the double arrow 13. slidably mounted. This transverse shaft extends substantially perpendicular to an upwardly open vertical shaft 17 for receiving the ink cartridge 10.
