Description

[0001] APPARATUS FOR SUPPLYING INK [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink supply device and an ink supply device for supplying ink to a printer.

It is called DIGITAL PRINITING that when a publicity material such as a banner, a poster, a signboard, a frame panel, etc. is produced, Since the output can be used by outputting all the shapes such as a desired photo or image to a material, the use thereof is rapidly increasing.

For example, in the case of a banner, a cloth may be used as an output material. In the case of a poster, a paper is output from a printer. Various types of jade , Internal and external signboards, and vehicle advertisements can be printed out using a PVC material (media) as an output material, and also used as an interior decoration for interior decoration.

However, in the large-sized printer, such a large-sized printer outputs ink as an ink. In general, a large-sized printer is provided with cartridges for outputting various kinds of color inks to a material.

That is, in a small printer connected to a home computer (PC), the amount of ink used is small so that the ink is usually embedded in the cartridge. However, in the case of a large printer, as described above, Therefore, an ink pack (storage container) in which ink is stored is installed in the cartridge, thereby supplying ink to the head of the printer.

Specifically, as shown in Figs. 1 and 2, after the ink pack (storage container) 1 storing the ink is inserted into the case 2, the case 2 is inserted into the supporting member 3, The needle 7 is passed through the discharge portion (rubber drum dog) 1a of the ink pack 1 and the ink is supplied to the printer through the needle 7.

In the course of using the ink supply device, the shape of the needle 7 is deformed and its position is also changed by various external forces, so that the ink 7 flows into the needle 7 from the ink pack 1 The ink leaks to the outside of the needle 7 as shown in FIG. 3, and further, the ink pack 1 may be damaged. In addition, in the process of removing the leaked ink when the ink leaks, a safety accident may be caused by the sharp end of the needle 7.

According to another embodiment of the prior art, as shown in Fig. 4, a method of refilling the ink in the ink tank 9 is utilized.

However, such a system can introduce foreign matter such as dust when ink is supplied, and can cause serious damage to the printer head due to foreign matter. Since the ink tank 9 keeps the ink in the ink tank 9 always in contact with the air for refilling (the ink pack of Fig. 2 is vacuum-packed), bubbles are generated in the ink during the supply of the ink And the concentration of saturated oxygen may increase. In such a case, there is a problem that nozzle detachment occurs in the printer and the quality of the output is deteriorated.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a storage container having a solid position fixing structure without using a discharging structure penetrating the needles, Which can continuously confirm the capacity of the ink supply device.

Referring to the drawings, the present invention includes a storage container 100 in which ink is stored, and a support body 200 having a receiving groove 210 in which the storage container 100 is received.

Here, the storage container 100 is a container in which ink is stored in a large capacity, and can be configured to store more than 3 liters of capacity, for example, more than a conventional large capacity.

This storage container 100 has a discharge valve 110 associated with the printer to supply stored ink to the printer. At this time, the discharge valve 110 can solve the problem according to the needle described in the prior art as an opening and closing discharge configuration, rather than a rubberized discharge configuration that is penetrated by a needle as in the prior art.

An ink tube (not shown) having a connection portion to be assembled while enclosing the discharge valve 110 is connected to the discharge valve 110 so that the ink is discharged through the discharge valve 110 and the ink tube Can be supplied to the printer. For reference, a supply amount adjustment unit (not shown) may be provided between the ink tube and the printer, and the supply amount of the ink can be kept constant before being supplied to the printer by the supply amount adjustment unit.

For example, the discharge valve 110 may be formed at a lower portion of one side of the storage container 100 so that the ink is discharged through the discharge valve 110 smoothly by its own weight.

The support body 200 has a receiving groove 210 for receiving the storage container 100 and the storage container 100 is inserted into the receiving groove 210. Accordingly, the storage container 100 can be stably fixed in the support body 200 when ink is supplied to the printer in association with the printer.

The support main body 200 is a main constituent feature of the present invention. The support main body 200 communicates with the receiving groove 210 and guides the discharge valve 110 to protrude outward when the storage container 100 is inserted. A guide fixing hole 220 for fixing the rear discharge valve 110 may be formed.

Specifically, the guide fixing hole 220 guides and fixes and supports the discharge valve 110, which is disposed outwardly from the storage container 100. To this end, the guide fixing hole 220 is formed on one side of the support body 200 And may be formed to be tapered.

More specifically, the guide fixing hole 220 may include an inlet portion 220a as a portion into which the discharge valve 110 is inserted, and a moving portion 220b as a portion to which the discharge valve 110 is moved.

Here, the inlet 220a is formed to be larger than the vertical cross-sectional area of the discharge valve 110 in the outward projecting direction, and the moving part 220b can be tapered from the inlet 220a.

Accordingly, in the process of inserting the storage container 100 into the receiving groove 210 of the support main body 200 in order to be stably received in the support main body 200, the discharge valve 110 smoothly moves outward easily The discharge valve 110 first protrudes outward through the inlet portion 220a of the support body 200 in the receiving groove 210 so that the outlet valve 110 can be protruded.

The inlet 220a is formed to be larger than the vertical cross-sectional area of the discharge valve 110 in the outward direction so that the discharge valve 110 is easily inserted into the support body 200 without interfering with the edge of the inlet 220a. As shown in FIG.

The discharge valve 110 is formed in a tapered structure of the moving part 220b communicating with the inlet part 220a in the process of pushing the storage container 100 deep into the receiving groove 210 of the support body 200 . The discharge valve 110 thus moved is moved to the end of the moving part 220b and is supported and fixed by the end of the moving part 220b so that the end where the discharging valve 110 is supported and fixed in the moving part 220b The discharge valve 110 has a shape corresponding to that of the support portion of the discharge valve 110, so that the discharge valve 110 can be firmly and smoothly fixed at the end of the moving portion 220b.

As described above, according to the present invention, the storage container 100 can be smoothly and easily guided by the tapered guide fixing hole 220 having the inlet portion 220a and the moving portion 220b, It can be inserted into the receiving groove 210, and a rigid position fixing structure can be obtained in a state of being inserted and received in the receiving groove 210.

For example, the guide fixing hole 220 may be formed on one side of the support body 200, and the tapering direction may also be formed as a downward tapered structure directed downward. Accordingly, the insertion operation of inserting the storage container 100 into the receiving groove 210, which is open at the upper part in the support main body 200, can be performed smoothly from the beginning.

The support base 200 may be provided with an inclined support 280 so as to support the ejection of the ink in the storage container 100 toward the guide fixing hole 220 side.

The inclined pedestal 280 has a downward inclined structure toward the guide fixing hole 220 and is disposed at a lower portion of the receiving recess 210 so that ink in the storage container 100 is discharged It can be moved by its own weight to the valve 110 side and discharged smoothly through the discharge valve 110.

That is, when the level of the ink in the storage container 100 is lower than the discharge valve 110 in the absence of the inclined pedestal 280, the storage container 100 is always Resulting in an inefficient ink supply in which a certain amount of unused ink remains.

Furthermore, the inclined pedestal 280 may be formed with an insertion groove 280a at an end of the discharge valve 110 so as to prevent a residual amount of ink from being generated in the storage container 100. [

The support fixing portion of the discharge valve 110 supported and fixed to the guide fixing hole 220 includes a support hole 112 between two support protrusions 111 spaced apart from each other at an outer surface of the discharge valve 110, One support jaw 111 disposed in the receiving groove 210 among the two support jaws 111 of the discharge valve 110 is inserted into the insertion groove 280a of the inclined support 280. [

If there is no insertion groove 280a as described above, one support jaw 111 disposed in the receiving groove 210 of the two support jaws 111 of the discharge valve 110 is supported on the inclined support 280 The substantial discharge level of the discharge valve 110 is formed to be high, so that the ink can not be sufficiently discharged into the storage container 100 and the remaining amount is generated.

Meanwhile, the storage container 100 and the support body 200 may be made transparent or semitransparent, so that the remaining capacity of the ink in the storage container 100 can be easily grasped.

Since the remaining amount of the ink can be easily confirmed by the naked eye, it is possible to stably supply the ink to the outputting printer, thereby preventing the loss of the printing due to the stopping of printing during the printing, It is possible to prevent the head from being damaged because it is not supplied.

In addition, a scale display unit 290 having a plurality of scales spaced apart from each other in the vertical direction may be formed on the support main body 200 so as to display the remaining amount of ink in the storage container 100 inserted into the support main body 200 have. The remaining amount of ink can be more accurately known by the scale display unit 290. [

As a result, as described above, according to the present invention, when the storage container 100 is inserted into the receiving groove 210 of the support main body 200, It is possible to adopt a rigid position fixing structure together with easy insertion.

In addition, according to the present invention, the inclined pedestal 280 downwardly inclined to the guard fixing hole side is formed inside the support main body 200, so that the remaining amount can be prevented from remaining when the ink in the storage container 100 is drained.

Further, since the storage container 100 and the support body 200 are made transparent or semitransparent, the remaining capacity of the ink in the storage container 100 can be easily grasped so that ink can be stably supplied to the printer It is possible to prevent a head loss due to an ink non-supply to the printer head, together with a cost loss due to an accident in which printing is stopped during printing.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
