Definitions
- EP-A 322 131 describes a device according to The preamble of claim 1 is known.
- a printhead an inkjet printer has several with foam filled chambers. The foam is inked soaked. A hollow needle is inserted into each chamber, which via a hose with a storage container is associated with free ink. If the ink supply is in the containers are used up, the containers with Refilled bottles. When a reservoir is complete is emptied, however, is the restart problematic after refilling.
- the object of the present invention is to achieve Basically a device of the type mentioned to be specified, which enables safe commissioning. This task is characterized by the Features of claim 1 solved.
- the 1 has a housing 1 in which a carriage 2 can be moved horizontally.
- the Carriage 2 carries a print head 3.
- the print head 3 has several inkjet nozzles 4 and an ink supply, e.g. in Form of an ink-soaked foam body 5.
- a reservoir 10 is included free ink 11 (FIG. 3) with a free surface 12 arranged.
- the container 10 is vertical in a tub 13 movably guided and supported on springs 14.
- the spring constant of these springs 14 is dimensioned in such a way that the surface 12 is independent of the ink supply volume remains at approximately the same level. This level is slightly lower than the level of the nozzles 4, so that a slight negative pressure in the print head 3 is formed.
- the reservoir 10 is with the print head 3rd connected via a connecting line 20.
- This consists of a tube immersed in the ink 11 21, one inserted into the foam body 5 Hollow needle 22 and a tube 21 and the Needle 22 connecting, flexible connecting hose 23.
- a pumping agent is to be filled on the container lid 15 arranged.
- This is indicated in Fig. 3 as an air pump 26.
- the pump 26 shown in simplified form exists from a domed rubber membrane 27, which in the Has a hole 28 in the middle and on the edge of the container lid 15 is attached. Has below the membrane 27 the lid 15 an opening 29, the inside through a removable, flexible film tab 30 is closed. This forms a check valve.
- This pump 26 can be done manually by pressing the membrane several times 27 a little overpressure in the airspace above the Ink surface 12 are generated. With that the Ink 11 driven into the connecting line 20. As soon as this is filled, i.e.
- the air space above surface 12 pressurized again with atmospheric pressure.
- This can e.g. a rubber stopper 35 from an opening 36 of the Cover 15 pulled out above the surface 12 become.
- the vent can also be in the pump 26 be integrated.
- the ink supply according to the invention enables long, uninterrupted printhead operation 3 without needing to be replaced.
- Plotters for making drawings can e.g. about Night without supervision, what the today's inkjet plotters because of the limited ink supply is not possible in print head 3.
- feed devices described are suitable also for printheads 3 that do not have a foam body, but contain a cavity filled with ink.
