Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weaving machine weaving method used for producing a weaving weave having a large number of colors such as Nishijin weave.

[0002]

2. Description of the Related Art In Nishijin weave, which is known as the highest-class shuttlecock weave, the basic unit in the direction in which wefts are arranged, that is, the basic unit in the weaving direction is called "exit", and the basic unit in the direction in which warp threads are arranged is called "mouth".
The number of weft yarns is much larger than that of other shuttlecocks, and it is not uncommon that several tens of weft yarns are used for weaving one weft.
On the other hand, the shuttle box that houses the shuttle is 12 at maximum on one side.
One of the features is that there are only a few and the number of weft threads used is smaller than that used.

In such Nishijin weaving, when the design is completed, a design drawing is created prior to weaving. As shown in Fig. 1, the design drawing shows the design by color for each unit, and on the side of the design drawing, the color used in the design drawing, that is, the weft thread The use range of directions is color-coded and linearly entered. This is called a meter, and its arrangement is usually in the order of wide-use weft threads,
It often corresponds to the position of the shuttle in the shuttle box.

When the design drawing is completed, the operating order and the operating direction of the shuttle are determined in consideration of the meters. The movement order and movement direction of the shuttle are called exchanges, and the assembled exchanges are recorded on a given form. When manufacturing the woven fabric, the shuttle is operated according to the assembled replacement, and when the shuttle is operated, the vertical movement of the warp yarn is operated based on the design pattern. Before the introduction of the computer, the operation of the warp thread was performed by a paper pattern with punching holes.

[0005]

By the way, recently, the introduction of a computer is also progressing in Nishijin textile. As mentioned above, the operation of the warp thread was performed on the pattern paper, but even now with the introduction of computers, the word “textile paper” is widely used to represent the state of the warp thread when the shuttle operates. Used, the use of blank paper means that the warp threads are not manipulated so that no pattern is produced.

[0006] In the Nishijin machine weave in which a computer is introduced, the change of the shuttle and the movement of the warp yarn are input to the floppy disk. And by the floppy disk,
The shuttle is automatically operated along with the warp threads. However,
In many places where the meter arrangement is changed, the loom is still temporarily stopped and the shuttles are replaced by hand.

The change of this shuttle in Nishijin textile is
Previously, it wasn't a big deal. This is because the array of meters was hardly changed. However, if the meter is kept fixed, the weft thread is frequently caught and pressed, and the usage amount increases.
When the amount of weft yarns used for weaving the same pattern increases, the weight of the woven fabric becomes low, the commercial value decreases, and the woven fabric becomes expensive and loses competitiveness. Therefore, in recent design drawings, the arrangement of meters is finely changed. As a result, frequent change of the shuttles has become necessary, and the decrease in the productivity of the fabric due to the frequent stop of the loom has become a serious problem.

The present invention was devised in view of the above circumstances, and an object of the present invention is to provide a shuttlecock machine weaving method capable of efficiently producing a high-quality woven fabric with a small amount of weft thread usage. .

[0009]

SUMMARY OF THE INVENTION In a shuttlecock machine weaving method according to the present invention, the operation sequence and the operation direction of the shuttlecock when changing the accommodation position of the shuttlecock in the shuttle box are incorporated in the exchange of the shuttlecock, and the assembled exchange is carried out. By automatically operating the shuttle according to the above, even when the storage position of the shuttle is changed, the shuttle is automatically moved to the target storage position without stopping the loom.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a schematic diagram showing a metric arrangement changing portion in the design drawing, FIG. 3 is a schematic diagram showing a transfer procedure of the shuttle in the metric arrangement changing portion, and FIG. 4 is a schematic view showing a state of accommodation of the shuttle after the transfer. .

According to FIG. 2, meters are drawn in the order of ground, haku, middle yellow, purple, nand, grass, vermilion, red, brown, and white until n. For this meter, as shown in Fig. 3, the shuttles are placed in the shuttle box on the left side from bottom to top in the order of ground, haku, middle yellow,
It is assumed that purple, nando, grass, vermilion, red, brown, and white are stored in that order. In addition, as for the shuttle box, the one for both 10 is used here.

On the other hand, the meter from n + 1 Yue is
The order is ground, haku, middle yellow, grass, purple, dark purple, white, vermilion, brown, red, and nando. In other words, the number of colors has increased from 10 to 11 by the addition of dark purple, and the meters after 4 chome have been changed except for red and red. Along with this, as shown in FIG. 4, the shuttles are housed in the order of 1 to 9 steps from the bottom of the left shuttle box in the order of ground, haku, middle yellow, grass, purple, dark purple, vermilion, red and nando, and the right side. In the shuttle box, the 7th and 8th rows from the bottom are white,
Each shall contain tea.

In order to shift the shuttle from the state of FIG. 3 to the state of FIG. 4, in the shuttleless machine weaving method according to the present invention, the shuttles are moved in the order shown in FIG. move. At this time, the warp threads are in a pattern-free state, that is, in a state where blank paper is used. In fact, if you used blank paper,
The number of sheets used is eight. In order to reduce the number of empty sheets used, if there is a shuttle that can be moved by the time when the change over n is completed, the change can be performed at the time of change over n.

The purple contained in the 7th tier from the top of the left shuttle box is transferred to the 7th tier from the top of the right shuttle box. The nand stored in the 6th tier from the top of the left shuttle box is moved to the 6th tier from the top of the right shuttle box. The grass stored in the 5th row from the top of the shuttle box on the left,
Move to the 5th step from the top of the right shuttle box. The tea stored in the second tier from the shuttle box on the left side,
Move to the third tier from the top of the right shuttle box. The nando that was moved to the 6th level from the top of the right side shuttle box is returned to the 2nd level from the top of the left side shuttle box. The white contained in the first tray of the left shuttle box is moved to the fourth tray from the top of the right shuttle box. The grass transferred from the top of the right side shuttle box to the fifth level is returned to the seventh level from the top of the left side shuttle box. The purple transferred from the top of the right side shuttle box to the seventh level is returned to the sixth level from the top of the left side shuttle box.

Due to the above, the shuttle is automatically shifted from the state of FIG. 3 to the state of FIG. However, the dark purple on the fifth row from the top of the shuttle box on the left side has not been stored yet. During ~, there is no interference between warp and weft, so no pattern is formed. Also, although there is some interference between the weft threads, it is limited to one over, so
Weft consumption due to the interference is not a problem. When the operation of is finished, the exchange after n + 1 is started. The stop for putting dark purple in the fifth row from the top of the shuttle box on the left side is put, for example, after the ground yarn of n + 1 crosses has run.

Such exchange of the shuttles is incorporated in the normal exchanges or after the exchanges having a stop at the arrangement change position of the meter are assembled once. In either case, the exchange is automatically assembled based on the design drawing data, the metric data, etc. and input to the floppy disk. Further, the stop switching list as shown in FIG. 5 is displayed according to the data input to the floppy disk. The list of FIG. 5 shows the stop switching from FIG. 3 to FIG. 4, and is a stop which is entered after the running of the n + 1-over ground yarn, and indicates the addition of deep purple. The circled numbers in the figure showing the accommodation position of the shuttle are the metric line numbers (chome).

If the shuttle is automatically operated by such replacement, the loom is not stopped even when the accommodation position of the shuttle in the shuttle box is changed. The loom is stopped only when the number of colors is added or decreased. In addition, the number of operations for removing the shuttle is drastically reduced. Therefore, the woven fabric is efficiently manufactured. Also,
Frequent meter re-arrangement is possible because metric re-arrangement does not lead to reduced productivity, which results in a reduction in the amount of yarn in the fabric. Further, by displaying the list, the weft thread can be pulled out without error, and the accommodation state of the shuttle in the shuttle box can be grasped, so that accurate repair can be performed even when the weft thread is broken.

The method of moving the shuttle when changing the accommodation position of the shuttle is not limited to (1) to (5). Generally, the movement order and the movement direction of the shuttle are determined in consideration of the following points.

The number of movements of the shuttle, in terms of blank paper, should be as small as possible in order to avoid unnecessary movement of the shuttle.

As shown in FIG. 6, when the shuttle is stored in the shuttle box on one side both before and after changing the storage position of the shuttle, when the shuttle is returned from the shuttle box on the right side to the shuttle box on the left side, , Move the shuttle to the next storage position. However, as shown in FIG. 7, after the shuttle is once returned to the shuttle box on the left side, it is possible to change the accommodation position of the shuttle by using an empty paper.

If the same shuttle is subsequently moved with an empty paper, the weft thread will cause it to hang. Therefore, avoid this as much as possible. When fluttering is unavoidable, the weft thread can be hooked on a small amount of warp thread to prevent fluttering. In this hooking, the position is selected so that the pattern generated by the hooking is covered with the pattern of the other color.

When moving the shuttle, avoid the movement of the shuttle which causes the shuttle box to move up and down. If such a need arises, take measures such as temporarily moving the shuttle to an intermediate position or moving the shuttle that should not be moved.

The shuttle is not operated while being housed in the shuttle box,
When the loom continues to operate, the shuttle may move inside the shuttle box, and the shuttle may gradually come out of the shuttle box. Therefore, when weaving is continued without being operated while the shuttle is stored in the shuttle box, the maximum allowable number of operations of the shuttle is determined in advance, and when the shuttle reaches the predetermined number of times, the shuttle is automatically moved and replaced. Good to do.

[0024]

As described above, in the case of the shuttleless machine weaving method according to the present invention, when the accommodation position of the shuttle is changed, the change is automatically made. Although the number of operations of the shuttle is slightly increased by this automatic replacement, the weaving machine is not stopped and the operation of replacing the shuttle is not required, and as a result, the fabric is efficiently manufactured. The automatic change of the shuttle may cause the interference of the weft thread, but the interference is limited to more than one, and rather, the arrangement change of the meter does not lead to the inefficiency, so that the frequent change of the meter becomes possible. Needless to say, the effect of reducing the yarn amount is much greater.
