The outlet 22 drilled in the enclosure 21 is automatically sealed when the cartridge 20 is mounted on the mounting table 40 for ink injection.

The mounting table 40 is fastened to the support frame 10 by fasteners 41 and 41 so as to support and fix the cartridge 20 into which ink is not injected, and the cartridge 20 is inserted into an inner center thereof. The storage space 42 is formed so that the ink can be injected in the state where the cartridge 20 is inserted into the storage space 42 when the ink is injected, and after the ink is injected, the cartridge from the mounting table 40 It is easy to separate by just lifting 20.

As shown in FIG. 3, the filling device 30 is fixedly arranged to be adjacent to the mounting table 4 fixed on the support frame 10, and the filling device 30 is disposed at least one side by side to fill each filling device 30. By filling ink in the cartridge 20, which is placed on the mounting table 40 by means of 30, ..., or at the same time, each filling device in one cartridge 20 having a space defined therein. 30, 30, ...) to sequentially fill the ink of various colors.

The filling device 30 is supported and fixed to the slider 51 mounted on the base 50 orthogonal to the support frame 10 so that the filling device 30 is cartridged by the cylinder 52 attached to the slider 51. It is comprised so that it may move up and down to the upper side of 20.

The filling device 30 is composed of an ink injection device 31 and an air suction device 36, the respective devices (31, 36) are nozzle holes (311, 361) of the housing (310, 360) made of a hollow body as shown in FIG. The pins 32 and 37 are provided to intervene, and the pins 32 and 37 are fixed to the respective cylinders 33 and 38 installed on the upper side thereof, so that the pins 32 and 37 are cylinders 33 and 38. It is configured to open and close the nozzle holes 311 and 361 by moving up and down by the &quot;

One side of the housing 310 of the ink injection device 31 is provided with a reservoir 34 for temporarily storing the ink supplied from the ink tank so that the ink of the reservoir 34 passes through the ink injection device 31 for the cartridge ( 20, and a hose 390 connected to the vacuum pump 39 is connected to one side of the outer circumferential surface of the housing 360 of the air suction device 36, thereby providing a cartridge 20.

The air inside is discharged to the outside to make a vacuum inside.

The cylinders 33 and 38 move through the nozzle holes 311 and 361 while moving the pins 32 and 37 of the ink injection device 31 and the air suction device 36 based on a signal preset in the controller 60. To control.

The operation relationship of filling ink in the cartridge by the ink filling system of the present invention configured as described above is as follows.

First, in the present invention, once the cartridge 20, the container 21 and the lid 25 are separated, and the inside of the container is cleaned cleanly, and then the lid 25 is closed to seal the inside tightly. 20 is mounted so that there is no flow to the mounting table 40 of the support frame (10).

When the cartridge 20 is mounted on the mounting table 40, the operator operates the switch of the controller 60 to measure the amount of ink required from the tank 34 in which the ink is stored and to supply the ink to the storage tank 340. The cylinder 52 is operated to lower the slider 51.

The filling device 30 descending by the cylinder 52 is formed when the ink injection device 31 and the air suction device 36 are in intimate contact with the ink injection hole 26 and the air suction hole 28 of the cartridge 20. The cylinder 52 is stopped without lowering abnormally. At this time, the cylinder 52 can limit the conveying distance of the cylinder by adjusting the stroke.

When the cylinder 52 stops operating, the controller 60 again operates the cylinder 38 together with the vacuum pump 39 attached to the air suction device 36 to operate the nozzle hole 361 of one of the air suction devices 36. ) Is moved to the upper side, and the nozzle hole 361 is opened.

Then, the air in the cartridge 20 is all discharged to the air intake device 36 through the air inlet 28 and the open nozzle hole 361 by the air intake of the vacuum pump 39, so that the inside of the cartridge 20 Is converted to a vacuum state. At this time, the other ink injection hole 26 is blocked by the ink injection device 31 in which the nozzle hole 311 is closed so that the outside air does not flow into the ink injection device 31 but only the air remaining therein. It is discharged to the outside to achieve a vacuum state.

When the cartridge 20 is evacuated, the controller 60 again closes the nozzle hole 361 using the pin 37 driven by the cylinder 38 of the air suction device 36 and at the same time, the other ink injection device. By operating the cylinder (31) side 33 and moving the pin 32 blocking the nozzle hole 311 upward, the ink that has been metered from the ink tank and supplied to the reservoir 34 is supplied to the ink injection device 31 through the hose. After being injected into, it is injected into the ink inlet 26 of the cartridge 20 through the nozzle hole 311. Since the cartridge 20 is in a vacuum state, all of the ink in the ink injection device 31 is filled into the cartridge 20 by the vacuum suction input of the cartridge 20.

In this way, when all the ink is filled in the cartridge 20, the controller 60 drives the cylinder 33, which has been raised so far, to block the nozzle hole 311 using the pin 32. Will not be injected.

After the ink filling operation is completed in the cartridge 20, the controller 60 moves the ink injection device 31 and the air suction device 36 to the upper side by operating the cylinder 52 of the filling device 30 again. When the cartridge 20 filled with ink is lifted from the mounting table 40 and packed, all the work is completed.

As described above, the present invention can be used repeatedly as long as the cartridge is not damaged by refilling and refilling the cartridge using a filling system. As a conventional method, the manufacturing cost required for cartridge manufacturing is greatly reduced by disposing of the cartridge once after use. In addition, it is economical because consumers can receive cartridges at a lower price.

On the other hand, the ink filling system of the present invention has been described as an embodiment in which only one type of ink of a single color is injected into one cartridge, but in the case of a color printer, ink of various colors is filled together in the cartridge.

In addition, the color printing cartridge is formed with a plurality of ink discharge ports through which the respective ink filled in the respective spaces separated from each other in the housing, and only one ink injection hole is drilled through the lid.

Therefore, when a single cartridge has a plurality of compartments, each space should be able to inject necessary ink.

To this end, in the present invention, the ink injection device 31 'for injecting ink into the cartridge 20' is configured in the same manner as the ink filling system described above, but the ink injection device 31 'is shown in FIG. ) Can be linearly reciprocated up and down by the cylinder 52 placed in the base 50, the air suction device 36 'to remove the air from the cartridge 20' Only the structure attached to the mounting base 40 'is fixed.

In the above configuration, the air suction device 36 'has the same number as the outlets 22', 22 ', ... formed in the cartridge 20' as shown in FIG. Suction devices 36, 36 ', .... block each ink outlet 22', 22 ', ..., or one side of the air

When the nozzle hole of the suction device 36 'is opened, the remaining ink discharge port is blocked.

As described above, the present invention always installs only one ink inlet in a color printer cartridge having a plurality of internal spaces, so that ink is always injected into the ink inlet even when different ink is injected into the ink inlet by each ink injector. It can be filled only in the space that makes a vacuum by the air suction device.

In addition, the cartridge used in the color printer is provided with a mounting table having the same quantity as the plurality of ink injection devices which are to inject different inks like the air suction device.

Therefore, if you want to fill the cartridge with ink, first fill the cartridge with one ink injection device and move it to the other side while moving to the ink injection device side for the ink injection into another color. When the ink is sequentially injected, the ink can be repeatedly used by refilling only the ink for the color printer cartridge as described above.

As described above, according to the present invention, by providing a filling system capable of collecting a cartridge that is out of ink and refilling the cartridge again, the ink is not disposable and used only once, rather than being disposable. When the filling is repeated, it is possible to use a number of times, so that the manufacturing cost of manufacturing the cartridge again as in the related art is greatly reduced.

In addition, the present invention has the effect that the consumer can be provided with the ink cartridge at a lower price by using the cartridge repeatedly, it is much more economical than the conventional.
