Definitions
- the present invention relates to an ink supply mechanism of an ink jet printer for continuously supplying ink to an ink jet head for a long time without interruption.
- the ink jet head 10 is a medium such as a sheet mounted on a platen 20 (recording medium) 30.
- a platen 20 recording medium
- Direction or vertical direction (front and back sides in the figure), and eject ink droplets from the nozzles 12 arranged on the bottom of the ink jet toward the surface of the media 30 so that 2.
- An ink jet printer that prints a picture or / and a character composed of an array of a plurality of ink dots is well known.
- an ink supply cartridge 60 is replaceably inserted into an ink supply port 50 provided in the printer body 40 as shown in FIG.
- the ink is supplied to the ink jet head 10 from the ink supply port 50 through a flexible long resin tube 52 or the like.
- the ink supplied to the ink jet head 10 is ejected from the nozzles 12 arranged on the lower surface of the ink jet head toward the surface of the medium 30 mounted on the platen 20. I have.
- the ink supply port 50 is shown enlarged away from the printer main body 40 to clarify its structure.
- the ink jet printer having such a structure replaces the cartridge 60 when the ink of the cartridge 60 is used up and exhausted.
- the ink filled in the new cartridge 60 can be easily re-supplied to the ink jet head 10 simply by replacing another new cartridge 60 with the ink supply port 50 of the printer body.
- the handling of the supply mechanism is excellent.
- an ink jet printer having such a structure is continuously operated for a long time, day or night, the printer user may not be able to monitor, become unmanned, become unmanned, etc.
- the ink of the power cartridge 60 inserted into the ink supply port 50 of the printer body sometimes disappeared. Then, the printer is stopped or the printer is operated in a so-called idling state (in spite of the fact that the printer is operating, the media is running) without the ink-depleted cartridge 60 being replaced with another new power cartridge 60. Picture or characters are not printed at the same time).
- the cartridge 60 supplying ink inserted into the ink supply port 50 of the printer must be unattended.
- the cartridge is replaced with another new cartridge 60 that is sufficiently filled with ink, such as at night before the battery is changed to a new one.
- An object of the present invention is to provide an ink supply mechanism (hereinafter, referred to as an ink supply mechanism) of an ink jet printer that can solve such a problem.
- a first ink supply mechanism of the present invention includes a plurality of ink supply cartridges provided in an ink supply port provided in a printer body for supplying ink to an ink jet head.
- the replaceable cartridge extension section is connected via the ink flow path. Then, the ink is supplied to the ink supply port of the printer main body through the ink flow paths of the plurality of cartridges inserted into the cartridge extension section.
- the ink is continuously supplied from one of the plurality of cartridges inserted into the cartridge extension portion to the ink supply port through the ink flow path, and the remaining amount of ink in the one cartridge is reduced. When it becomes zero or near zero, it is detected and the ink of the next one cartridge inserted into the same cartridge extension is supplied to the ink supply port through the ink flow path.
- a second ink supply mechanism of the present invention includes an ink supply port provided in a printer body for supplying ink to an ink jet head. There is provided a dummy cartridge which can be exchangeably inserted with the cartridge, and a cartridge extension portion into which a plurality of ink supply cartridges can be inserted so as to be exchangeable.
- the dummy cartridge and the cartridge extension section are connected to each other via an ink flow path. Then, the ink of each of the plurality of cartridges inserted into the cartridge extension portion is supplied to the ink supply port of the printer main body through the ink flow path and the dummy cartridge inserted into the ink supply port.

It is advisable to insert another new fully-washed washing cartridge 120. Then, in the same manner as described above, the cleaning liquid of the new cleaning cartridge 120 is supplied to the ink flow path 90, the ink flow path 72 inside the dummy cartridge and the ink jet head using the switching means 130. It is better to circulate through the nozzles 12 lined up with the nozzle and discharge them to the washing liquid receiving tray installed below the nozzles 12.
- the ink remaining in the ink flow path 90 or the ink flow path 72 of the dummy cartridge / the nozzle 12 be continuously and sufficiently washed with the cleaning liquid.
- the printer user is surely notified of the fact that the cleaning liquid of the cleaning power cartridge 120 inserted in the insertion portion 84 of the cartridge extension portion has run out so as not to overlook the printer user. You should be able to do it. Then, the printer user replaces the cleaning cartridge 120 that has been used up with the cleaning liquid and has replaced it with another new cleaning cartridge 120 that is sufficiently filled with the cleaning liquid. It is good to be able to replace the insertion part 84 without delay.
- the ink supply cartridge 60 inserted into the slot 82 of the cartridge addition section and the cleaning cartridge 120 inserted into the insertion section 84 of the cartridge addition section It is better to use the same size and the same structure as the general-purpose cartridge 60 to be inserted into the ink supply port 50 of the printer, but the structure and size are different from the general-purpose cartridge 60. It is also possible to use
- the dummy cartridge 70 preferably has the same external shape and the same size as the general-purpose cartridge 60, but is different from the general-purpose cartridge 60. Different shapes and sizes are possible.
- the second ink supply mechanism when the dummy cartridge 70 has the same size and the same outer shape as the general-purpose cartridge 60, Can insert the dummy cartridge 70 into the ink supply port 50 of the printer body in a replaceable manner with a general-purpose cartridge 60 for supplying ink.
- the ink supply port 50 into which the general-purpose cartridge 60 is exchangeably inserted is connected to a general ink jet printer provided in the printer main body 40 without changing the structure of the printer at all.
- the second ink supply mechanism can be optionally used as it is. In other words, instead of a general-purpose power cartridge 60 for supplying ink to the ink supply port 50 of the printer main body, only a dummy cartridge 70 is replaced, and the printer has a second ink supply mechanism. It becomes possible.
- the first and second ink supply mechanisms are applicable to printers that use various inks such as water-based pigment inks, water-based dye inks, solvent inks, oil inks, and UV inks (inks that cure by irradiation with ultraviolet light). It is.
- the first and second inking supply mechanisms supply ink to the inkjet head 10 for inks of different colors such as yellow (yellow), magenta (red), cyan (blue), and black (black). , Respectively.
- the plurality of ink supply mechanisms allow inks of different colors such as yellow, magenta, cyan, and black to be continuously supplied to the ink jet head 10 without interruption for a long time. And supply it.
- first and second ink supply mechanisms allow ink of only one color of yellow, magenta, cyan, and plaque to be continuously supplied to the inkjet head 10 without interruption for a long time. Of course, it is also possible to supply them.
- the first and second ink supply mechanisms of the present invention are widely used in an ink jet printer having a structure in which an ink supply port is provided in a printer main body and ink is supplied to the ink jet head from the ink supply port. It is possible. Further, in the second ink supply mechanism of the present invention, the printer main body is provided with an ink supply port into which an ink supply cartridge is replaceably inserted, and ink is supplied to the ink jet head from the ink supply port. It can be used as an option for any type of ink jet printing without changing the structure of the printing.
