Description

200406516 (1) Description of the invention: [Technical field to which the invention belongs] This volume relates to a device that maintains the straightness of jetting water used for weft-injection of water-jet loom to stabilize weft-injection. [Previous technology] Non-shot shooting weaving ~~ / Move on to enter the office. It is speculated that this phenomenon is caused by the upward movement of the box formed by a plurality of pieces of… placed between the upper and lower mouth gold parts side by side (for example, Lingzhao Patent Document i). The principle of weeping and tick / machine generation is that after beating up, u% after weaving, the air on the side of the weaving mouth is pushed ^ ^ 1 to the side of the buckle, and then when the weed advances, the attracted air That is pushed ^ a AU sentence on the juice. In addition, the phenomenon that the spray water moves upwards is caused by high speed and provincial bismuth P taxis and yagu. It is easy to occur, and the spray 4 moving upwards causes warp damage. Therefore, in order to make the spray water pass through the warp yarn opening ', it is necessary to improve the rigidity of the spray water from the weft-injection nozzle, or it is difficult to increase the straightness by considering the upward movement. With the direction of the jet, such an adjustment

Patent Document 1: [Summary of the Invention] Japanese Patent Publication No. 41 758 (the first problem to be solved

The invention of JiJg's husband: The present invention was developed in consideration of the above-mentioned situations. ^ It is a dry hand that solves the problem by suppressing the swinging motion of the 筘. ^ In order to solve the problem, the present invention is based on the name above The part is provided in the form of a 200406516-body or an individual body, and a member extending on the mouth side of the warp yarn opening. When weaving the loom at high speed, the warp direction protrudes into a bow shape. ιφ η transport to the opening — arched. Among them, the warp opening range here is 2 warp yarns: the range of the maximum warp openings when running beyond the limit. In other words: “Opening the siege without false banknotes” means to open up and down, respectively, “the bismuth hole (combined eye) and the weaving mouth, the silk thread of Zhaxi 9 Shifu” ... 2 straight lines connecting my mouth, and The 2 straight lines. Set the component in the area surrounded by the opening of the warp yarn. In order to prevent the damage of the warp yarn, it is better to damage the Si. ′ Take the component and set it outside the opening of the warp yarn, and outside the range where the warp yarn runs beyond the limit. Consuming the other features of this month, it is in the way of the lower side or as a unit. 1 It is ancient as the earth ° 丨 It is placed on the side that extends into an integrated side, beyond the opening of the warp and facing the weave. The feature body is provided in a manner that the supporting member is formed into a body or a member. in! The area of the yarn opening, which extends towards the weaving mouth side, if it is located on the lower mouth part or on the box holding member, it is more susceptible to damage than the swing center of Λ. The mouth plate moves and the impact of the party is also small, so it is less ^ in = ^ in the σ gold part or 15 retaining members (hereinafter referred to as the mouth gold part temple) in the direction of the weft insertion 1, see, or only set in Any position within full width. Second: In the case where the Γ gold section becomes an individual, it is also possible to install a member whose width is narrower than the full width in the latitude direction, such as the section, so that the position can be adjusted in the direction of the gold X ,, and early. Similarly, if the width of the component in the weft-feeding direction is different from :: in the component g to the structure #, the width of the component installed in the structure can be changed. Among other special features, jetting jets * ~ there are members that extend from above the range of the weft-feeding nozzle to the weaving mouth side. The feature of jetting jet = is that the box tooth is provided with a member ′ below the jetting nozzle 2 from the weft-injection nozzle and extends to the weaving mouth side. The pinch is maximum 7, so: the front end of the air resistance bulges more than other parts and the direct water hits the component. The nucleus of plutonium. Another component is installed to avoid spraying the component, and it can also be set in multiple pieces. King 4 may have only other features of the present invention, and the length direction of the system is at right angles. "The extension direction of the piece, relative to the box tooth = angle" refers to an angle that can be visually recognized as a substantially right angle, and is not an angle that requires a precise numerical value. Moreover, the angle here is formed by m ^ cattle Among the angles, the angle is located on the side of the warp yarn opening ^ shooting area. The other feature of the present invention is the curved part of the structure. There is an opening on the tooth side of the box, the front part of the component and the right side Μ Μ Μ The special feature of the curved part of the opening of the Μ is in the various aspects of the present invention described above, which is regarded as "", the opening of the gold section is provided as a body or as an individual. The components of the water jet loom's "Technical Wefting Girl's Equipment" and "the teeth (5) are provided above the front end range (17) of the water injection nozzle sprayed from the weft injection nozzle 200406516 (0) and headed to the weaving mouth.

The seventh flat shown in FIG. 4A is also extended. Π faces the doorway lower than the flat portion of the airflow suppressing portion 9. The eighth to tenth examples shown in the curved portion 4D are curved. The section 丨 1 is opened in the state shown in Fig. 4B to Fig. 8 and the eighth example is an example in which the portion of the airflow suppressing section 9 to the sprocket 5 is a bent section 11, Then, the airflow is suppressed from ST: the entire part is made into a curved part U. The seventh example of P 9 as shown in FIG. 4A is to make the curved part 1 arc-shaped. So-come, by bending The part 11, compared with the example of less than a semicircle, can smoothly guide the airflow downwards, and can prevent people from being injured. Since it is arc-shaped = eight cases, it is a curved part U An example of a semicircular shape. Dishan Nine Cases 'The front part of the airflow suppressing part 9 is composed of the curved part I on the base side] and the curved part 12' The curved part 11 is semicircular and reversely bent. The tenth example of a circular arc shape that is less than a semicircle in the direction of opening is that the airflow suppression part 9 is curved as a whole, and the front 11 is arc shape that is less than a semicircle.

In the tenth example of the basis, any of the examples is all the front ends b in the field which are closer to the 9th part than the airflow suppression part 91 = the place a. The place far away from the air-suppressing soil (the place where it is easy to touch the hand) is located at the bending part U 10 200406516 'Therefore, it can prevent people from being injured more than the seven cases of the younger ... Use the air-suppressing part of the warp opening to the air-suppressing part: one side ) To suppress the airflow to be inhibited :: Partly, take the side of the tooth of the q king in the direction of the curved part ^ smoothly, and hunt this, to suppress the upward airflow. The tenth _ ^ ^ _ example of the more stable and stable device than the seven cases of the younger brother is shown in FIG. 5, and the special feature lies in the fact that the air-k suppression unit 9 is an individual, in the upper and lower mouth. The neighbors 70 produced Meng Yan 7,8 different σ 7, 8 Set the airflow suppression section 9 &amp; β installed and the position can be adjusted to the weft-throwing direction, and the moon dagger 180 was set. In the latter case, the gold = restraining portion 9 is also set to be able to set F at the upper and lower mouths, and the position of the breast can be adjusted to the weft insertion direction. The 7,8 'system is opened to form the upper part of the front sheet 13 and the κ ^ 哉 哉, and the rear end of the keratome C and the rear sheet 14 are raised, so that 1, 5, 1 and 6 are away from the square clothes of the teeth 5 The full width extension # of the film along the right angle and the direction of weft insertion is formed by opening screw holes ii on the mounting plates 15, 16 at intervals of one hour, 0 days, X Wang Jian extension. Also, the 'air flow suppression section 9' is a ratio The full width is also narrow, and at the opposite bank 蟫 H, the direction of the slave weft-the position of the screw hole H is formed. The ϋ, which is not shown in the picture. Hunting this, 筘 4, as shown in Figure 6, The settings of the plates 15, 16 are symmetrical up and down and left and right, even if the box is fixed to the 或 holding member 3 after the box is up or down or left and right = 18 °, the air flow suppression section 9 is still set. The place of the king of clothing and the king of Sochi is convenient to use. Fourteen examples of the twelfth m 7D jelly device of the weft-stabilizing device are shown in Figure 7A, 7B, and 7C. The characteristics of the examples are: the airflow suppressing part 9 is set on the box tooth 5, shot from the $, the front side of the water jet _ Π, and extends to the side of the weaving mouth 200406516 10, Wei see the sprocket 5 and air flow suppression Qiu 〇 ~ One body. In addition, the airflow suppression part 9 ° 9 in any of the examples forms a right-angle direction formed by the length direction of 5. It is the twelfth example with the teeth, which is in the front end range of the spray water 17 and before the spray water The airflow suppression section 9 is provided below the rudder 17. The 13th example of the airflow suppression section 9 is not provided. The fourteenth example is the flow suppression section 9 at the front end of the spray water. The airflow suppression section 9 is a type = sprayed on the felt paper disposed on the side of the counter-feeding yarn. The test method is based on the speed of the loom. · WOO, sec. Test conditions, the full length of the box in the weft input direction, two teeth. Full length in the length direction: 35_ The reference is inclined downwards 15.

The test results are shown in Figures 8A to 8D in terms of Type i to Type 4, Figures 9A to 9D are in terms of Type 5 to Type 8, and Figure 10A and Figure 8 show Type 9 and Type 10 in sequence. . The shaded area 18 in the figure is a place where the paper is discolored (a place where water touches). The hatched area 18 is an area where the actual discoloration state of the pressure sensitive paper is simplified and expressed. In the figure, the shaded area 18 greatly exceeds the opening range of the warp yarn, but the test is as before? The state of no warp is installed to carry out 'so the state of the actual warp in the farm.' He shoots water in the warp opening range 2 Qiu .y yI hardly spread.外 Outside the opening range 2 According to Figures 8 to 10, compared to the box of type 2

Most of the types 3 to 4 of the suppression section 9 τ n ± W ^ / JlL 18, / / ^, the hatched area is shot ^ 隹 ® shape ^ This can be said to be caused by the provision of the airflow suppression section 9 in. Also in the above test of Type 2 and Type 1 (1, the crankshaft angles of the main shafts at 90 ° and 90 ° are from 90 to 215. The shape of the front end is continuously jealous. The result is θ 4 4 and the feeling of He Sheshui ^ / type 10 (with the moon shape of the airflow suppression part 9), which is more concentrated than the case with only the box type + 1 9 shape. Compared to y, the above test results of the front shape of He Sheshui are summarized in Figure 11 * Master A The center of the hatched area of 1 is the reference table pair value, which is based on the pattern momentum and the amount of movement in the weaving direction .: Table; The suppression part 9 reduces the amount of upward movement. Equipped with airflow suppression section = the shape of the moving dan in the direction of &amp; cross-wefting and weaving, which reduces the amount of movement and private movements more. In the case of type 9, 'to 13 200406516 weaving direction The increase in the amount of movement is caused by the airflow from the bottom to the upper side of the airtight side of the airtight side of the airtight side of the airtight side of the airtight side of the airtight side of the airtight side of the airtight side of the airway. The device is not limited to the above example. For example, the airflow suppression section 9 in the form shown in the second to tenth examples is a It is limited to the upper opening gold part 7, and it can also be provided to the lower opening gold part 8. Also, the extension part of the component 9 can also be outside the limit operation range of the warp. In this case, the component 9 extends above and below the name 4 The range of the portion is smaller than that outside the opening range of the warp yarn. Therefore, the air resistance of the member 9 becomes smaller.

发明 之 功 # The present invention uses a member extending to the weaving mouth side to suppress the updraft generated in front of the fS that swings during weft insertion, thereby inhibiting the weft injection nozzle to shoot water on the water. As a result, the adjustment of the spraying direction of the spraying water becomes easier, and the wefting becomes more stable. Therefore, it is possible to prevent the warp yarn from being damaged by the weft-injection water, and to reduce the amount of water and the pressure of the ejection water when weft-in.

In addition, due to the swing of the buckle, the airflow usually changes above and below the member. However, if the member is extended in a direction perpendicular to the longitudinal direction of the box tooth, the extension direction of the member becomes the tangential direction of the swing of the box. The member is eliminated. Changes in airflow caused. b. The front part of the upper part on the right side has an opening toward the tooth side ^. When the upward airflow in the warp opening is suppressed by the side of the airflow suppression part, the suppressed airflow escapes away from 筘Part: I the curved part is flat, and the ground is at least guided to the lower side, so that the updraft can be ^ ^. In addition, it is possible to prevent a person from being injured by the bent portion. 14 200406516 [Brief description of the drawings] (I) Schematic part Figure 1 is a side view showing the first example of a weft-stabilizing device. 2A, 2B, and 2C are side views showing the second, third, and fourth examples of the weft-stabilizing device.
