Description of the Related Art Conventionally, when weft insertion is performed by using a water jet, in order to sufficiently transmit the velocity of the pressure water to the weft and generate a desired conveying force for the weft, It has been considered preferable to make the thickness of the water film of the water jet formed around the weft yarn sufficiently large. Therefore, the flow passage cross-sectional area of the tip opening of the nozzle for injecting the pressure water is set to a value as large as possible.

れていた。Further, the longer the existing length of the pressure water in the weft inserting direction is, the more the weft conveying force increases. Therefore, the existing length of the pressure water in the weft insertion direction tends to be as large as possible so as not to affect the warp shed. Therefore, if the plunger stroke of the pump is constant, the cross-sectional area inside the cylinder is determined in consideration of the flow-path cross-sectional area of the nozzle tip opening and the length of the pressure water in the weft inserting direction.

うという問題もあった。In the case of the above-mentioned conventional technique, when the pressure of the pressure water to be jetted is increased in order to increase the flight speed of the weft as the loom speed increases, There has been a problem that the convergence of the tip of the pressure water is reduced and the tip of the pressure water tends to scatter around.
The scattered pressured water has a problem that it collides with and damages the warp yarns, warp lines are generated to deteriorate the quality of the woven fabric, and further, warp yarn breakage occurs. In addition, there is a problem in that the pressure water that has been scattered causes the warp yarn opening to become defective, resulting in a weft insertion defect, thereby decreasing the loom mobility. Further, since there is a tendency to increase the flow path cross-sectional area of the nozzle tip portion and the existing length of the pressure water in the weft insertion direction, the amount of water used for one weft insertion also increases. There was also.

定条件を求めたものである。In the water jet loom, the tip of the pressure water is scattered not only due to the increase in the pressure of the pressure water but also due to the water film thickness of the pressure water. That is, if the water film thickness is large, the cross-sectional area of the pressure water in the direction perpendicular to the weft inserting direction becomes large, so the resistance received from the air when the pressure water moves increases and the tip of the pressure water scatters. It is thought that. Therefore, the present invention reexamines the conventional concept that the thickness of the water film of the water jet and the existing length in the weft inserting direction may be increased in order to obtain a desired conveying force for the weft. In order to set the optimum and minimum amount of water to obtain the desired conveying force, various experiments have been repeated, and the optimum nozzle cross-sectional area and pump that can obtain the desired conveying force with a small water film thickness. This is a condition for setting the cross-sectional area.

少ないものである。As described above, by setting the cross-sectional area of the nozzle tip opening and the cross-sectional area of the cylinder of the pump,
With the minimum water film thickness and water amount, pressure water capable of generating a desired conveying force for the weft yarn can be jetted from the weft inserting nozzle. And, the fact that the water film thickness of the injected pressure water is small means that the cross-sectional area of the pressure water in the direction perpendicular to the weft inserting direction is small, and the resistance received from the air during the movement in the warp opening is small. Even if the moving speed of water is the same as the conventional one, the tip of the pressure water is less likely to scatter, and the pressure water has good convergence. Therefore, the scattering of the pressure water is also small.

The maximum weft insertion rate at which both the operating rate of the loom and the operating rate of the loom can be maintained favorably and plotted as shown in FIG. The nozzle cross-sectional area SN is a value correlated with the water film thickness of the pressure water, and the cross-sectional area ratio SP / SN is the length of the pressure water in the weft inserting direction.

Even with M, the weaving width is 2.0 m and the loom rotational speed is 700
Even in the case of RPM, both are considered to be equivalent.

件であることが分かった。From FIG. 4, the conditions for obtaining a result exceeding the conventional limit of weft insertion rate of 1300 (m / min) were obtained. (1) Nozzle cross-sectional area SN = 1.3 to 1.9 mm 2 and (2) Ratio of nozzle cross-sectional area SN to cylinder cross-sectional area SP It was found that the weft insertion condition was in the range of SP / SN = 90 to 115.

稼働率や織布の品質が低下してしまうものであった。On the other hand, the nozzle cross-sectional area SN is 1.3.
Even if it is up to 1.9 mm 2 , if the cross-sectional area ratio is 80 to 90, the amount of pressure water is small and the length of pressure water at the time of weft insertion becomes too short, resulting in stable weft flight. Without doing so, the loom mobility tends to decrease. On the contrary, the cross-sectional area ratio SP / SN is 1
If it exceeds 15, the length of the pressure water at the time of weft insertion becomes longer, but the longer the pressure water is, the longer the jetting time becomes, and at the rear end portion of the pressure water flying in the warp opening, it is closed. It becomes easy to collide with the coming warp threads. As a result, warp breakage may occur and the weft may be damaged. Therefore, the operation rate of the loom and the quality of the woven fabric are deteriorated.

Even if it is 5, when the nozzle cross-sectional area SN exceeds 1.9 mm 2 , the tip of the pressure water tends to scatter,
Similar to the problems of the conventional technology, the operation rate of the loom and the quality of the woven fabric are likely to be deteriorated.

3 to 1.9 mm 2 and (2) the weft inserting condition within the ratio SP / SN = 90 to 115 of the nozzle cross sectional area SN and the cylinder cross sectional area SP shows a weft inserting ratio higher than the conventional one, It constitutes the water jet loom of the present invention.

稼働率も向上するものである。According to the water jet loom of the present invention, the water film thickness of the pressure water required to obtain a predetermined conveying force becomes the minimum value, and even if the pressure water moves at the same speed as the conventional one, The scattering of the pressure water is reduced as compared with the conventional one, and the pressure water is less likely to collide with the warp during weft insertion. Therefore, damage to the warp yarns is reduced and the quality of the woven fabric is improved. Further, since the weft insertion failure due to the warp breakage and the warp opening failure does not occur, the operation rate of the loom is improved.

Is. In addition, since the warp is less likely to come into contact with the reed blade and bend due to the collision with the pressure water, that is, the collision with the pressure water, the frictional force between the reed blade and the warp during beating is reduced. ,
It is also believed that the reed wear will be reduced. In addition, since the amount of water splashed is reduced, the amount of water that adheres to peripheral parts is also reduced, rust can be suppressed, and the life of parts can be extended.
