Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a jet nozzle 1 for weft yarn introduction in a spray chamber, and in particular, it has an excellent performance which is indispensable for obtaining high-speed operation. Convergent high-speed water jet nozzle. [Known Technology] The jet chamber of the automatic knitting machine is equipped with a jet nozzle that can convert the high-pressure water supplied by the pump into a jet stream to perform the weft transfer and the weft introduction. This type of jet nozzle includes a rectifier for rectifying the high-pressure water supplied by the pump in the nozzle body, and a spray hole for sequentially narrowing the flow path of the high-pressure water on the downstream side of the rectifier. A member; and a needle having a yarn exit hole arranged on the same shaft. The jet water flow is released from the gap between the reduced diameter angle Θ portion of the nozzle hole member and the outer diameter oblique portion (reduced angle angle portion) at the tip of the needle, and has the function of transporting the weft yarn in a predetermined direction by the jet water flow. An important issue for the jet nozzle is how to turn the high-pressure water supplied by the pump into a rectified state as much as possible to produce a jet stream of water with excellent convergence. Conventional nozzles for introducing weft yarns are disclosed in, for example, Japanese Unexamined Patent Publication No. 62-88779; Japanese Unexamined Patent Publication No. 4-18053. These jet nozzles are those who want to use the rectifier to turn the high-pressure water supplied by the pump into a rectified state as much as possible, and then obtain a jet stream with good convergence.

Description of the invention €) A By providing a hollow portion that can suppress cavitation on the downstream side of the rectifier, jet nozzles for releasing a stable jet of water are released. Although these jet nozzles have been gradually improved and developed to this day, their initial stage The structure of the nozzle of the stage is formed by the structure shown in Fig. 11 and Fig. 12.

Description of the invention P) This rectifier 8 series is formed with: slits that can divide the internal flow path into a plurality of radial cross-sectional shapes, which can be borrowed The high-pressure water supplied from outside is passed through these slits to rectify the high-pressure water. In addition, the relationship between the nozzle hole member and the needle of the conventional jet nozzle is composed of the form shown in FIG. The angle of inclination β of the diameter reduction of the nozzle hole 7 in the exit direction is generally 6 to 12 degrees, and especially in the knitting industry, 8 to 12 degrees are mostly used. The angle 0 of this inclined plane is generally thought that if the angle is to be small, the jet water flow released from the outlet of the nozzle member will be concentrated at a sharper angle, which is better. In addition, the range of the bevel angle α of the diameter reduction of the needle tip toward the downstream side is 2 to 5 degrees, and among them, needles having a bevel angle of 5 degrees are particularly used. In addition, the length 1 from the corner 7b of the outlet of the nozzle member to the tip 2 2 of the needle protruding therefrom is about 1 mm to 1.5 mm. [Problems to be Solved by the Invention] The required characteristics of the jet nozzle include: good convergence and less diffusion of the jet stream; fast velocity of the jet stream; strong force to transport the weft by the jet stream; and the need to transport the weft It consumes less water; moreover, it can correspond to the high-speed operation of the hydraulic knitting machine and can achieve a stable weft introduction operation. These required characteristics are achieved by improving the convergence of the jet stream released from the nozzle of the jet. Therefore, people have been working on inventions or creations that seek to improve the convergence of the jet stream for a long time. However, the countermeasures used to improve convergence in the past are based on the fact that this paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 public love)-6-ϋ I nnnn V It aK ft n * t) SJ_ nn I fi n I (please read the notes before you fill out this page and then fill out this page) 4 Consumption Cooperation by Employees of Intellectual Property Bureau of the Ministry of Economic Affairs 3 4 3 3 6 A7 -------- V. Description of Invention θ) The bevel angle α of the needle 3 is 2 to 5 degrees, and the bevel angle β of the nozzle member 7 is in the range of 6 to 12 degrees. The smaller the angle Θ is, the better the concept is. For the structure of the rectifier, The study of materials and how to create a flow path that can reduce the fluid resistance of high water is mainly designed. In addition, as shown in FIG. 10 (c), the conventional nozzle for weft thread introduction described above “high-pressure water injected into the nozzle from the eight water injection holes 2 will lie on the outer periphery of the needle 3 in the assembly chamber and collide with each other. Because turbulence is caused, a pressure loss will occur, and the turbulent flow state after the turbulence will flow to the rectifier 8 ′. Therefore, there is still a limit to using the rectifier 8 to perform the rectification function. Therefore, 'the traditional jet nozzle can fully cope with the condition that the operating speed of the hydraulic knitting machine is less than 1 000 rpm. However, the speed of the 7 low-power knitting machines in the future, 100 rpm is only the minimum speed, which has been It is required to reach above 1 200 rpm, and even up to I 500 rpm. Therefore, the speed of such an ultra-high-speed hydraulic knitting machine still has a problem that it is impossible to achieve stable weft introduction for a long time. In addition, the shape of the needle is the outer diameter portion of the front end of the inclined surface portion 5 of the needle 3 shown in FIG. 13, and it is a monomer, scale, and the like that easily accumulate and disperse the fibers dispersed in the circulating supply water. As a result, the jet of water released from the gap between the inclined surface 7 a of the nozzle member and the needle 3 will be diffused outward due to the existence of deposits attached to the tip of the needle 5 of the needle 3. Changes in the flying direction and angle of the jet water flow (weft) cause the convergence of the jet water flow to deteriorate. In view of this, the present invention provides a jet nozzle, regardless of whether the speed of the hydraulic braiding machine is 100 rpm or above 1200 rpm, and even the Chinese National Standard (CNS) A4 specification (210 X 297 mm) is applied to this paper size- ----- I -----— — — — — — — I— ^. --- I ---- Jun (Please read the notes on the back before filling this page) Employees of the Intellectual Property Bureau of the Ministry of Economic Affairs Cooperative Du Printing 4 343 3 6 A7 _______B7__ 5. Description of the invention θ) Under ultra-high-speed running conditions up to 1 500 rpm, the jet water flow still has excellent convergence, and can achieve long-term stable weft introduction. [Means to solve the problem] The jet nozzle of the first invention of the present invention has a plurality of water injection holes on the outer peripheral wall of the nozzle body, and a weft thread introduction needle is coaxially installed inside the nozzle body.

Nozzle member, and a jet nozzle provided with a rectifier for rectification on the upstream side of the nozzle member, characterized in that the front end portion of the needle is an exit corner portion that intersects from the downstream flow path of the nozzle member and the downstream end face When the protruding length is 1, and from the intersection of the extension line of the bevel angle (reduction angle) Θ of the flow path of the nozzle member and the extension line of the bevel angle (reduction angle) α of the needle tip to the exit When the length dimension up to the corner is L; the relationship between the two is 1 = θ / 360. X10LXY, where Υ 値 is in the range of 0.2 5 to 0.7. Thereby, the jet water flow released from the gap between the beveled inner surface of the nozzle hole member and the outer diameter inclined surface of the needle front end portion can reduce the amount of air attracted from the weft hole 4 of the needle 3 within a proper range. Compared with the traditional jet nozzle, it can play a higher speed and better closing performance, and the weft yarn transporting power is stronger, and does not generate diffusion flying maggots and so on.

Description of the Invention f) The fifth invention is combined separately, Can achieve better nozzle performance. [Embodiment of the invention] FIG. 1 is a longitudinal sectional view of an important part of a jet nozzle of the present invention, and is a nozzle body 1 that is supplied with high-pressure water from a valve plunger in conjunction with the operation of a hydraulic braiding machine. The needle 3 is coaxially assembled. The hollow nozzle body 1 is an outer peripheral wall of a substantially middle portion in the axial direction, and an appropriate number of water injection holes 2 are provided at regular intervals along the circumferential direction, and the same high-pressure water can flow from these water injection holes 2. The needle 3 assembled on the inner side of the nozzle body 1 penetrates a yarn hole 4 for weft in the axial direction. When assembled to the nozzle body 1, a needle hole 3 is formed from a position rearward than the water injection hole 2 The bevel portion 5 of the outline shape that tapers toward the front at the bevel angle Θ (refer to FIG. 7). The outer diameter of this inclined surface portion 5 is reduced toward the front end, and the front end is assembled so as to protrude slightly from the end of the inclined surface portion 7a of the nozzle member. In the nozzle body 1, a nozzle member 7 and a rectifier 8 shown in Fig. 10 (b) are assembled coaxially, respectively. Furthermore, the nozzle hole member 7 is assembled into a portion corresponding to the inclined surface portion 5 of the needle 3 so that an annular flow path cross-section is formed between the inclined surface portion 7 a of the injection hole member 7 and the inclined surface portion 5 of the needle 3. A gap 9 is formed which can be used to accelerate the high-pressure water into a jet of water. As described in the description column of the conventional technology, the high-size paper flowing from the water injection hole 2 is applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) -1〇.

Description of the invention ㊁) Pressurized water will be in the assembly room (picture 1, remove it) The space between the needles 3 on the outer wall of the partition wall 10) collides with each other, which results in pressure loss or flows to the rectifier 8 in a disordered turbulent state. Therefore, the rectifying effect of the rectifier 8 still has its limit. As a result, it is not possible to obtain a high-speed jet of water with excellent convergence, and thus it is impossible to fully meet various characteristics required for the nozzle for weft introduction. Therefore, in the present invention, a partition wall 10 is provided between the water injection hole 2 and the water injection hole 2 in the axial direction of the nozzle body 1. Therefore, the collision of high-pressure water on the outer periphery of the needle can be avoided. Before flowing into the rectifier 8, it has been rectified beforehand, so that it can pass through the gap 9 after it has been rectified almost completely, so that it can generate a high-speed jet water flow with excellent convergence. Fig. 2 is a longitudinal sectional view of the nozzle body of the present invention; Fig. 3 is a sectional view taken along line a_a in Fig. 2. In addition, the cross-sectional view taken along line b_b in FIG. 2 is the same as the cross-sectional view of the rectifier part shown in FIG. 6 (b), and therefore description thereof is omitted. In FIG. 3, a partition wall 10 is formed between the water injection hole 2 and the water injection hole 2, that is, on both sides of the water injection hole outlet 2a. It is preferable that the front end of the partition wall 10 is a position adjacent to the bevel portion where the pin 3 does not contact the needle 3. In addition, although the cross-sectional shape of the partition wall 10 is preferably a triangular shape with the front end shown in FIG. 3, it may be a rectangular front end or a circular arc end with the same thickness. . The sprayer nozzle of the present invention is provided with a partition wall between the water injection hole 2 and the water injection hole 2.

Description of the invention P) 1 〇, the directionality of the high-pressure water after water injection can be determined, which can improve the rectification of the collection room. As a result, the turbulent flow easily generated in the conventional nozzle for weft introduction can be greatly reduced, and the rectifier 8 supplies water that has been rectified in advance, so that it can further exert an excellent leveling effect. Therefore, the jet water stream ejected from the nozzle of the jet can obtain a jet water stream with higher convergence and higher speed which has not been achieved in the past. Fig. 9 is a conceptual diagram for explaining an important part of the amount of air attracted by the jet of water from the yarn hole 4 of the needle 3. In FIG. 9, the jet of water flowing along the surface of the bevel portion 5 of the needle 3 is released from the tip of the needle 3 toward the bevel angle α of the needle, and then, because there are a large number of bevel angles toward the nozzle hole member 7 The action of the jet water flow released in the direction of Θ receives a concentrated force from the tip of the needle 3 toward the direction indicated by the dotted line and at the same angle as the bevel angle 0 of the nozzle member. The conical portion surrounded by the dotted line from the tip 22 of the needle in FIG. 9 becomes a vacuum state due to a high-speed jet of water. Therefore, it is equivalent to a vacuum container that can absorb air from the yarn hole 4. Therefore, the amount of air sucked from the yarn hole 4 is proportional to the volume of the tip of the needle and the volume of the conical portion surrounded by the dotted line. Therefore, the amount of air sucked from the yarn hole 4 tends to be such that the smaller the bevel angle 0 of the nozzle hole member 7, the larger the amount of air it sucks. However, since the conventional jet nozzle system forms the inclined angle Θ of the orifice member 7 from 6 to 12 degrees, the amount of air absorbed from the yarn hole 4 of the needle 3 is considered to be more than necessary.

Description of the invention (! 〇) was mixed into the jet stream and released Therefore, the more the air is mixed in, the lower the density of the water forming the jet water flow is, so the conveying force for conveying the weft yarn is also weakened. Therefore, the conventional jet nozzle has too much air mixed in the jet water flow, so even if the rectification of the pressure water is improved or the flow path of the high-pressure water is made into the most appropriate shape, the convergence of the jet water flow is improved. The performance still has its limits, and due to the large number of flying scatters from the jet water stream, it is easier to damage the weft yarn. In addition, for high-speed operating conditions where the speed of the hydraulic weaving machine exceeds 1000 rpm, the speed of the jet water stream or the Disadvantage of insufficient transport power. In the present invention, the inclined angle β of the nozzle hole member 7 is formed to 15 to 35 degrees, and preferably 15 to 30 degrees, thereby reducing the amount of air mixed into the jet water flow and generating A jet of water with more excellent convergence. In addition, the jet water stream released from the jet nozzle of the present invention is very high-speed and has a strong force for transporting weft yarns, so there is no problem when the speed of the hydraulic braiding machine is 1000 rpm, even if it exceeds 1200 rpm or even more than 1500 rpm. High-speed running conditions allow stable weft insertion for a long period of time. Fig. 5 is a longitudinal sectional view showing an important part of the present invention and a conventional jet nozzle enlarged. In FIG. 5, the inner diameter of the injection hole member 7 is a release opening that is reduced in diameter on the inner side surface 7 a of the inclined surface portion toward the downstream side at an inclined surface angle 0 and is enlarged toward the outer diameter side from the position of the exit corner portion 7 b. 10 formed. In addition, the outer side 5 of the beveled surface of the needle 3 shown in FIG. 5 is reduced in diameter toward the downstream side at an inclined angle Θ, and the front end 2 of the needle 3 is a paper standard of China National Standards (CNS) A4 (210x297 mm).

Description of the invention (11) It is assembled so as to protrude from the position of the exit corner 7b of the nozzle member 7 to the position of length 1. The bevel angle 0 of the needle 3 of the conventional spray nozzle is 2 degrees to 5 degrees, and the bevel angle Θ of the nozzle member 7 is 6 degrees to 12 degrees, and the protruding length of the tip of the needle exceeds 1 mm, and Most of them are made from 1.0 to 1.5 mm. The conventional jet nozzle with a protruding length 1 of the tip of the needle of 1.0 to 1.5 mm and a bevel angle of 6 »of 6 to 12 degrees, although it can be presumed that it is based on long-term experience and consideration of the convergence of the jet stream. It is adopted as the optimal size, but because the amount of air sucked in from the yarn hole 4 of the needle 3 and mixed into the jet water flow is too much, the speed is more than 1000 m Pm, especially more than 1 200 rpm Regarding the speed of the hydraulic knitting machine, 'it is still unable to produce a jet of water for stable use. Fig. 6 is a longitudinal sectional view showing an important part of the constitutional elements of a jet nozzle of another invention of the present invention. In the present invention, the bevel angle 0 of the injection hole member 7 is set to 15 degrees to 35 degrees, and preferably 15 degrees to 30 degrees, and the protruding length 1 of the tip of the needle can meet 1 = 0 / Relational expression of 360 ° X10LXY.

The protruding length 1 of the tip of the needle must be smaller than the aforementioned size L. It is an absolute condition. Assuming that the protruding length 丨 is greater than the size L, then the tip of the needle will become the paper size applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm ^). 14-(Please read the notes on the back before filling out this page) tr --------- So 丨 printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, printed by the staff of the Intellectual Property Bureau of the Ministry of Economic Affairs 4 34 3 3 β Α7 Β7 V. Description of the invention (! 2) Compared with the extension line of the bevel angle Θ of the nozzle member 7 shown in FIG. 3, the result is more prominent. 1 It was originally intended to converge along the bevel angle 0. The jet water flow will collide with the tip of the needle and spread out, so it will hinder the convergence of the jet water flow. In addition, the aforementioned relationship can also be rewritten as: 1 / L = 0 / 36O ° X 1 OxY, and Y 値 is 0.2. A range of 5 to 0.7 is particularly preferred, a range of 0.2 to 5 is 0.5, so 1 / L is also equivalent to 1 0 Θ / 3 6 0 ° X25% to 10Θ / 360.

Therefore, other inventions in this case are made by making the nozzle body into Let the bevel angle 0 of the nozzle member be 15 degrees to 35 degrees, and the protruding length 1 of the tip of the needle conforms to the relational expression of 0/360 ° xlOLx 0.25 to 0/360 ° X10LX0.7, thereby 'can play : Of course, there is no problem when the operating speed of the hydraulic knitting machine is 1 000 rpm, even if the jet water flow required for ultra-high speed operation exceeding 120 rpm or more is excellent; there is no jet water flow that diffuses the flying maggots; and High-speed and strong weft-jetting water jets; further reduce the functionality of the water weaving machine per 1 ι · ριη, etc. In addition, for reference, the nozzle of the jet nozzle of the present invention A component that specifically calculates the length of the protruding length of the tip of the needle 1-for example, the following. First, the angle θ of the bevel of the needle is 5 degrees, and the outer diameter of the tip of the needle is 1 _ 4 mm; the exit corner of the nozzle member The diameter of this paper is 2 · 1 mm and the wattage of this paper is compliant with China National Standard (CNS) A4 (210 X 297 mm) -15-__________I I * I__ (Please read the precautions on the back before filling this page) Order --------- Smart Money Board members Η case consumer cooperative printed clothes 4 34 3 3 6 A7 ________B7 five, description of the invention) the angle β is 30 degrees, the size L system is 1.4mm.

[Embodiment 1] A spray nozzle provided with a partition wall according to the present invention having a size of: outer diameter of a needle = 2.0 mm, diameter of an exit corner portion of a nozzle hole member = 2.7 mm and 2.8 mm was used for a nozzle of 1 5 Weft yarn with 0 denier / 4 8 monofilament and 2 2 40 twist / meter, was introduced at the speed of 700 rpm of the hydraulic weaving machine and the shuttle stroke was 70 mm. Compared with the conventional weft introduction nozzle, the slip phenomenon is 10 degrees earlier when viewed from the cam rotation angle. This phenomenon means that the convergence of the jet water flow is good and that the weft introduction is ended early. The scattering of the water jets at the detector unit (at a position of 1900 mm) for detecting the arrival of the weft yarn is almost invisible, but it converges very much, and the weft yarn can be transported stably. [Example 2] Convergence of the jet water flow generated by the nozzle for weft introduction shown in Fig. 1 of the present invention and the conventional jet nozzle having the nozzle body shown in Fig. 10 was based on the following experiments: Compare. First, high-pressure water generated by a valve plunger pump with a hydraulic braiding machine operating speed of 1000 rpm and a cylinder inner diameter of 12 · 5 m m and a stroke of 11 m m was supplied to a jet nozzle.

Description of the invention ¢ 4) (Please read the notes on the back before filling in this page) About the method of evaluating the convergence of the jet water, the thickness is 15 mm. The gypsum board was set at a distance of 2 meters from the nozzle of the jet, and the hydraulic knitting machine was operated for 1 minute, and the sizes of X, Y, and z eroded by the jet of water were measured for evaluation. (1) The traditional nozzle for weft introduction: X = 5 5 mm; Y = 45mm; Z = 20mm. (+ 2) Nozzle for weft introduction according to the present invention: X = 2 5 mm; Y 22.5 mm; 0 mm. The above results show that according to the jet nozzle of the present invention, the diameter of the end portion of the jet water flow converges to about 1/2 of the same part of the conventional nozzle, and because the convergence is good and the density is high, The transportation force is very strong. [Embodiment 3] The employee's cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs has printed the tip of the needle as shown in Fig. 7 to reduce the diameter to a smaller outer diameter than that formed by the bevel angle β of the needle. The needle was assembled into a conventional nozzle body, and then a test for the weft introduction operation was performed. The results are as follows. First, it was found that the scale and the adhesion and accumulation of the fiber monomer were extremely rare. Secondly, even after a long period of weft introduction operation, even if a few scales and fiber monomers accumulate, the diameter of the front end of the needle is reduced to a small extent, so that the jet water does not spread to the outside at all. In addition, because the front end of the needle is reduced in diameter, the jet of water released is also strong due to the reduced diameter of the front end of the needle.

Description of the invention 〇9) And 'this implementation The degree of convergence of the jet water flow measured in the examples is shown in Table 1. It can be seen from Table 1 that X 値 measured by the conventional nozzle is very large ', indicating that the amount of water splash after diffusion is large. Moreover, γ 値 is large, but Z 値 is small, which shows that the convergence of the jet stream is poor, and the jet stream has a low velocity and weak water potential. Secondly, the A-type nozzle of the present invention corresponding to the claim 4 of the present application, no matter how the bevel angle 0 of its orifice member is changed between 15 ° and 35 °, all show its splash The diffusion range is small. Therefore, both X 値 and Y 値 are small, and the convergence is good. The water potential is very strong, so the Z 値 is larger than that of the traditional nozzle (see Table 1). Secondly, the X-type and Y-type nozzles of the B-type and C-type nozzles of the present invention corresponding to claims 5 and 6 of the present case are smaller than the A-type nozzles of the present invention, showing that they have very little water spray. And Z 値 is close to Y 値, and it can be seen that the convergence of the jet water flow is very good, the velocity of the jet water flow is fast and the water potential is very strong. [Effects of the Invention] The jet nozzle of the present invention can exhibit the following performance and effects. (1) The present invention is because a partition wall is provided between the water injection hole and the water injection hole, which can eliminate the phenomenon that high-pressure water collides with each other at the outer periphery of the needle 'and that the flow has entered a rectified state before it enters the rectifier. Since the pressure loss in the nozzle for weft introduction is reduced, a high-speed water jet can be obtained with excellent convergence. As a result, the interference of warp yarns caused by the water spray scattered by the jet stream can be almost completely eliminated, and a powerful paper size of CNS A4 (21QX 297) can be obtained.

Description of the invention? 〇) The power of conveying weft yarns can be achieved to introduce the weft yarns stably. (2) The present invention is to assemble a needle with a reduced diameter at the front end of the needle to a conventional nozzle body or the nozzle body provided with a partition wall between the water injection hole and the water injection hole of the present invention, thereby obtaining a more excellent Convergent and high-speed jets of water prevent the warp yarn from being disturbed at all, and the knitting machine can operate at high speed, which can remove deposits attached to the tip of the needle, which can significantly reduce the number of man-hours required for maintenance. (3) The present invention is to arrange at least two rectifiers in a plurality of stages, whereby the external appearance of the nozzle body is almost the same shape as the conventional nozzle body, but it can obtain a jet stream of water with excellent convergence. The warp is hardly disturbed, and stable weft insertion can be achieved. In addition, by combining the first, second, and third inventions of the present invention separately, the multiplication effect can be exerted to provide an ideal weft yarn introduction spray. (4) The amount of air drawn in from the needle hole of the needle can be reduced to the minimum required, so the amount of air mixed into the jet stream is reduced, and there are few diffused droplets (water sprays) in the jet stream, which can release convergence Jet water stream with excellent performance. (5) Because the spray water jet has few diffused droplets, it will not cause warp yarn to fluff or damage the warp yarn. (6) Because the jet water flow with high speed and strong weft conveying force can be released, weaving machine can be introduced stably for a long period of time at a weaving machine speed of more than 1200 rpm, which cannot be achieved by conventional jet nozzle The work can therefore be achieved.

C) a? ______B7_____ 5. Description of the invention? 1) (7) Because it is possible to obtain a jet of water with excellent convergence, only a small amount of water is required to achieve the work of introducing weft yarns, so it is more economical. (8) Even if the speed of the weaving machine is the same In addition, the weft conveying force of the jet water flow is also very strong. The pump system for generating high-pressure water can use a lower pressure than the pump used in the traditional jet nozzle, so it is more power-saving. (9) Each time the size of the needle and the orifice member is changed, the traditional method must first perform a number of tests to introduce the weft before determining the protruding length of the front end of the needle, but as long as i = 0 / 3 6 0. The relationship of X 1 〇LXY can easily calculate the protruding length 1 9 (10) In addition, the first, second, third, fourth, and fifth inventions of this case can be combined together It can also provide the ideal nozzle for weft introduction by exerting the multiplication effect.
