残留する脱気インクの空気溶解を防止する技術に関する
ものである。Detailed Description of the Invention [Technical Field] The present invention relates to an inkjet recording device, and more specifically, the present invention relates to an inkjet recording device, and more particularly, to an inkjet recording device that uses air to dissolve degassed ink remaining in an ink supply tube used in a movable part in an ink supply system. This relates to technology to prevent this.
従来、インク供給系内の可動部に使用されるインク供給
チューブとしては、柔軟性に富み、かつ、耐インク性の

的とする。However, since polyethylene has a high air permeability, a large amount of air can dissolve into the degassed ink remaining in the ink supply tube in a short period of time, causing printing defects due to missing dots even when the printer is used normally. It had the disadvantage of causing The present invention aims to solve this problem.

実施例を図面に基づいて説明する。In order to eliminate these conventional drawbacks, the present invention uses a conventional strong ink-resistant plastic material such as polyethylene on the inside that comes into contact with the ink, and air-fills the outside that does not come into contact with the ink. The purpose is to prevent the degassed ink remaining in the ink supply tube from causing dot dropout during normal use by using a plastic material such as vinylidene chloride, which has extremely low permeation, so that there is no intervening air space. It is something. The structure and embodiments thereof will be explained below based on the drawings.

A two-layer tube is formed by adhering vinylidene chloride 3 with a wall thickness of 0.2 mm to the outside with an adhesive 2 such as polyolefin with a thickness of about 5 μm.

クジェットヘッド５に脱気インクを供給している。FIG. 2 shows an embodiment of the present invention, in which the inkjet head 5 mounted on the carriage shaft 4 is movable left and right. The supply tube 6 must be made of a flexible plastic material. Also,
When moving left and right, the head 5 experiences a pressure change of 1 J due to vibration, etc.
It must not give J. The ink supply system that supplies ink to the inkjet head 5 has a stainless steel pipe 8 that does not allow air to pass through from the ink tank 9 containing the degassed ink to the movable parts to prevent foreign matter such as dust from flowing into the head. Connect filter 7. From the filter 7 to the inkjet head 57, since the inkjet head 5 can move from side to side, an ink supply tube 6 which is flexible and has excellent bending resistance is connected to supply deaerated ink to the inkjet head 5. There is.

の間に大量のを気がとけ込んですぐに飽和してし１う。FIG. 3 shows that when ink is sealed in a conventional polyethylene tube and the double-layered tube described in the previous embodiment and the tube is left standing, the ink in the tube is dissolved by air, m'l1i-
It is expressed as a measurement value of nitrogen by gas chromatography against the standing time. According to this, despite having the same wall thickness, the polyethylene tube 100 quickly dissolves a large amount of nitrogen in a short period of time. I'm saturated.

せず、印字は極めて良好なものとなる。If a polyethylene tube is used as the ink supply tube 6, a large amount of air will be trapped even during the time when the degassed ink passes through the ink supply tube 6, causing microbubbles to grow in the ink and cavitation. This causes dots to fall out. However, in the case of the double-layered tube 200, since the amount of air permeation with respect to the standing time is extremely small, the degassed ink passing through the ink supply tube 6 is supplied to the inkjet head 5 with almost no air dissolved therein. . Therefore, no missing dots occur and the printing is extremely good.

シのインク量が決１シ、また侠求仕様から応答周波数が
決する。It was also stated in Jing that in an inkjet recording device, deaerated ink has the effect of dissolving and removing air bubbles remaining in the flow path and preventing air bubbles from being generated due to cavitation. In the design of an inkjet head, the number of nozzles in the multi-nozzle determines the required dot diameter, that is, the required amount of ink per dot = 5 - 1, and the response frequency is determined by the desired specifications.

限界溶存チッ素量を表わしたものである。尚９ノズルヘ
ツドでは、各ノズル間隔は１／７２インチ、２４ノズル
ヘツドでは１／１８０インチである。According to the experimental results that investigated the relationship between these basic specifications and the degree of deaeration of ink, Figure 4 shows the relationship between the number of nozzles and the required amount of ink ejected per dot, and Figure 5 shows the response frequency versus bubbles due to cavitation. This represents the limit amount of dissolved nitrogen in ink to prevent the occurrence of nitrogen. Note that for a 9 nozzle head, the nozzle spacing is 1/72 inch, and for a 24 nozzle head, the spacing between each nozzle is 1/180 inch.
図から９ノズルヘツドで約１．５ＫＨ２以上、２４ノズ
ルヘツドで約２ＫＨ２以上で動作するためには、ヘッド
として約８ ｐｐｍ以下のインクが必要であった。As can be seen from the figure, in order for the 9-nozzle head to operate at approximately 1.5 KH2 or higher and the 24-nozzle head to operate at approximately 2 KH2 or higher, the head required approximately 8 ppm or less ink.
第３因に示した例によれば、ポリエチレンチューブでは
数分〜数十分で、二層チューブで大体６５０〜４００時
間経過してはじめてａ ｐｐｍに達することがわかる。According to the example shown in the third factor, it can be seen that a ppm is reached in a few minutes to several tens of minutes in a polyethylene tube, and after about 650 to 400 hours in a double layer tube.

ものでなければならない。1 In order to suppress air permeation, it is important to make the wall thick and to use a material with a small permeability coefficient = 6- However, as mentioned in the example in Fig. 2, the ink supply tube has a high durability. It must have excellent flexibility and stability when moving the head.

性、曲げ易さ、からポリエチレンが最も適していた。The material used for the inside that comes into contact with the ink can be polyethylene, polypropylene, polyester, Teflon, nylon, etc., but polyethylene was the most suitable because of its price, bending resistance, and ease of bending.

When used as an ink supply tube, it was able to maintain bending resistance over 5 million cycles.

対し重要な材料を摩耗やキズから保護できる。Other ink supply tube embodiments include tubes having more than just two layers, including at least materials with low permeability coefficients such as those described above. According to it,
Ink resistance can also be imparted to the outer material, and the material, which is important for air permeation, can be protected from abrasion and scratches.

。Figure 6 shows the inner diameter j, 4tMI+outer diameter 2.6111. This is an example of a tube in which polyethylene, nylon, and polyethylene are used from the inside, and the float of each material is 0.21 an. Polyethylene has a large elongation at break and has excellent bending resistance, and by disposing it on the inside and outermost parts of the ink supply tube, the bending life of this ink supply tube can be increased.

Reference numeral 11 is a 2JWI tube whose inner material is polyethylene and outer material is nylon 6, and reference numeral 12 is a Teflon tube whose outer diameter is larger than that of the 2M tube 11. By handling with the Teflon tube 12, even if ink builds up on the two-layer tube 11, the surface will not be corroded. In addition, the Teflon tube 12 is heat resistant,
Since it has excellent abrasion resistance, it protects the two-layer tube 11. Furthermore, the increased rigidity of the Teflon tube 12 prevents the tube from vibrating or falling when the head moves during serial printing.

3 has been overturned. First, insert the tube 11 into the shrink tube 14.
It is passed through and then shrunk, making it easy to assemble and fit tightly.

ため、その間にインクが浸入しない利点もある。According to this embodiment, first, the spring member 13 prevents the tube from vibrating or falling down when the head moves, thereby preventing pressure fluctuations from being applied to the head and from contacting other members. Covering the shrink tube closely with the two-layer tube prevents the two-layer tube from vibrating little by little within the gap, causing pressure fluctuations to the head, and preventing damage to the surface of the head due to repeated blows. are doing. Furthermore, even if the carriage moves violently or there is a disturbance, the two-layer tube does not bend at a curved portion, but bends at a somewhat uniform curvature, which improves bending resistance. Furthermore, since the coating is closely bonded, there is an advantage that ink does not penetrate between the coatings.

By using all tubes made of polyethylene, polypropylene, etc., which have excellent reeds and bending resistance, p1
It is possible to supply stable deaerated ink to the inkjet head, which has the effect of preventing dot dropouts.
