Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a method for pouring gutter in a fluid-jet green gutter.

BACKGROUND OF THE INVENTION Generally, in a fluid injection type loom, a weft yarn supplied from a weft supply holder is inserted from a main nozzle into a warp enclosure via a weft sub-lengthening device and a W storage basket. For example, as shown in Fig. 1, the length of the weft Y supplied from the weft measuring section (shown @) is measured according to the weaving width by length measuring rollers 1 and 2 that constitute the sub-length device. The sub-length weft yarn Y is once stored in a storage device constituted by a nostle 3 and a storage vibrator 4, and as the gripper 5 is bent, the fluid is injected from the king nozzle 1 mounted on the slay 6. The weft yarn Y that is injected from the king nozzle 1 is formed by the kite holes 8a (shown in FIG. 2) K of the weft kite part ladles 8, which are arranged in parallel in the threading direction on the slay 6. The threads are inserted into the guide path T. This milling motion occurs when the guide m 8 enters the opening of the warp threads y1 and y2 formed by the upward movement of the belt 9, as shown in FIG. This is done when the weft is of a length that matches the width of the shaft of the shaft W.
When the weft thread is inserted into the thread, it is rotated in the direction of arrow P in Fig. 2 around the sleigh sword 10 supporting the sleigh 6 or the locking shaft 11, but at this time, the weft thread within the guiding axis T is The weft thread escapes from the guide passage T through the escape passage U formed by the escape slit 8b of the member 8, and the weft leaves a rut 71'' by the reed 12 which is erected in the soil of the sleigh 6, facing the kite part ladle 8. The needle thread Y1 and the child thread Y2 are inserted into the belt 9 while the thread sword 10 is rotated in the direction opposite to the arrow P.
The 1,000-th movement of the threads replaces each other, and the 01J j11 threads are woven into the woven fabric W. Then, the guide section row 8 returns to the misaligned position shown in FIG. 2 again.

By the way, in order to make sure that the weft thread during girth-filling runs stably without flying out through the arm exit opening 02 from the guide = @T, and to fully support the weft's water flow, we used a thread of 6t.
Auxiliary nostle 13 is installed at a distance of a pigeon in the direction of gating.
13A is provided. These auxiliary nostles 13, 13A are provided opposite to the kite hole 14 which has a large opening toward the formation 12, and as shown by the arrow in FIG. From there, you can complete the suspension of service by heading toward the guide (m) T.

As shown in Fig. 3, the 1Ijl shot from the auxiliary nozzle 13.13A is carried out sequentially from the main nozzle 1 side, rotating as the cotton yarn reaches the water level. When the yarn Y1 and the child yarn Y2 almost overlap and the weft yarn that has been inserted is gripped by the warp yarns Y1+y2, it is necessary to hold the weft yarn gradually f4v: even in the weft up to t2. An injection of 13A (designated Hl in FIG. 3) takes place.

The one stroke angle 0 of the Urasuke nostle 13 with respect to the gist-setting direction needs to be set to about 25°-45° during the weft flight. The weft threads fly all the way through the Rainai-dori I@T while being bent by the axillary vibrations such as the jet from the auxiliary nostle 13, but conventionally,
Since the auxiliary nozzle 13A L7)lIJi on the opposite side of gutter insertion is also unified to the above-mentioned setting, it is impossible to change the bent state of the cotton yarn to a straight state even in the flying end role. Therefore, the weft threads that have been fitted are beaten in a bent state and are woven into the fabric W in the bent state, which is a major drawback in terms of purchasing woven fabrics.

The completeness of the purpose was made in consideration of all the above disputes,
The objective is to provide a complete feeding method for fluid injection double ruts that can maintain the orientation of the weft in a straight line after the flight is completed.

Embodiment Hereinafter, an explanation will be given based on FIGS. 4 and 5 while referring to FIG. 2, which embodies the present invention. The weft Y, which is red and white (not shown), is ejected from the main nozzle 7 and is inserted into the guide passage T formed by the kite members 8 and 14. Similar to the conventional structure, auxiliary nozzles 13 and 13A are provided on the slay 6 with an appropriate gap in the gating direction, and the king nozzle 701u to
It is designed to be shot. This auxiliary nostle 13.13
The injection angle 0 (shown in Figure 4) with respect to the guttering direction of A is 25° to 45° to stabilize the weft flight and assist the landlord.
is set to . Further, on the side opposite to width insertion, there is a traction nozzle 1 having a spray angle 01 different from that of the auxiliary nozzle 13.
A pair of 5 are provided. This injection angle 01 is 00~2
It is set at 5°.

Now, as shown in Fig. 5, in synchronization with the flying range of the weft yarn being inserted into the guide passage T by the main nozzle 7, the king nozzle 70i! Fluid is sequentially injected from the auxiliary nozzles 13 of I. When the flying of the cotton yarn approaches the end, that is, when the tip of the weft yarn approaches the vicinity of the Yusuke nozzle 13A on the anti-poling side, jetting from both nozzles 13A (denoted by Hl in Fig. 5) begins. Both nozzles 13A at t1 when the weft finishes flying.
Although the jet (2) from the weft is stopped, the weft yarn flying in the guide passage T is bent due to the influence of the jet from the auxiliary nozzles 13, 13A. At m4, when the jet 02 from the opposite nozzle 13A is purified, the jets from the left nozzle 15711 and others (indicated by H3 in FIG. This continues until time t2 (when the L thread Y1 and the bobbin thread Y2 merge in FIG. 2). That is, the tip of the weft yarn that has finished flying is pulled toward the υ grain insertion side by the injection H3K from both pulling nosles 15, and this state continues until the same weft yarn is gripped by the fine yarns Y1+Y, 2 at the time of warp closure. .

Since the spray angle θ1 of the image traction nostle 15 is set at a shallow angle of 0° to 25°, the cotton thread that has flown while being fully bent within the guide JIltl T will be drawn into a straight line when it finishes flying. It is done. Therefore, the posture of the weft yarn in the guide passage T is maintained in a single shell line state, and the same weft thread is reeded. At times, a warrior or weaver escapes from the guide passage T through the entire escape passage U while maintaining this posture. The upper thread Y1 and the t thread Y2 are woven into the front W1, and the upper thread Y1 and the t thread Y2 are woven into the cloth W in a straight line as the belt 9 moves upward. That is, in the weft insertion method of the present invention, unlike in the case of the conventional centering method, the weft yarn is not drawn in a bent concave state, but is always drawn in a @ line state, and the desired weft without defects is obtained. You can get the print cloth.

It should be noted that the present investigation is not limited to the above-mentioned embodiments. For example, even after the end of the weft water foot, the injection H2 of the auxiliary nostle 13A on the opposite culm insertion side is continued for a while, and the injection H3 of the traction nostle 15 is The start time is the end of weft flying 11f
tl or later, arbitrarily changing the number of towing nozzles 15, using a kite part ladle with an auxiliary nozzle or a towing nozzle integrally formed, etc., without departing from the spirit of this research. It is also OJh to do it.

Effects As mentioned above, the weft insertion method of this study is to fully inject the fluid from the Sosuke nozzle on the anti-weft insertion side until the weft ends, and then from the end of the weft to the end of the warp opening. In the dark, by making the fluid flow from a towing nozzle installed on the weft side in a curved manner at a predetermined time, it was possible to maintain the same type of stability in a straight line after the weft had finished flying. What can be done with delayed effects?
