The front movable frame 4 is located at the center of the frame facing the front frame 2A. The front movable shaft 5 is fixed to the outside of the front frame portion 2A while being mounted so as to be rotatable with respect to the front frame portion 2A by the front movable shaft 5 fixed to the front frame portion 2A. Connected to a reversing motor 7 via a gear box 6.

Reference numeral 8 denotes a thread pay-out roll (man winding) installed in the front movable frame 4 for winding a warp T for dyeing a Kasuri pattern. It is rotatably supported by the front movable frame 4 by a support shaft 9 extending from both side walls. The male winding 8 is detachable from the support shaft 9, and the support shaft 9 is configured to rotate integrally with the male winding 8 by a motor.

Reference numeral 10 denotes a warp tension adjusting mechanism provided at one end of the support shaft 9 for applying a predetermined tension to the warp T mounted between the male winding 8 and a yarn winding roll (thousand winding) 22 described later. It is for. That is, when a kasuri pattern described later is printed on the warp T, the warp T
The tension is adjusted so as to apply the same amount of tension as the tension applied to the pattern. By adjusting both tensions in this way, it is possible to prevent the occurrence of pattern collapse.

As shown in FIG. 4, the warp tension adjusting mechanism 10 has a brake shaft 1 coaxial with one end of the support shaft 9.
1 is fixed, and a brake fitting 12 divided into two parts is disposed above and below the brake shaft 11 with a small gap therebetween. The upper and lower brake fittings 12 are fixed to the side wall of the front movable frame 4, and the upper and lower brake fittings 12 are respectively provided on the half-peripheral surfaces of the upper and lower brake fittings 12 facing the outer peripheral surface of the brake shaft 11. Shoe 13
Is attached.

Therefore, the upper and lower brake fittings 12,

The rear movable shaft 16 of the rear movable frame 15 installed on the rear frame 2B side is the same as the front movable shaft 5 of the front movable frame 4 installed on the front frame 2A side. The front movable frame 4 and the rear movable frame 15 before and after this are arranged on the axis.
8 is set so that it can be inverted 180 ° in synchronization. In the figure, S is a stopper for holding the front and rear movable frames 4 and 15 in a horizontal state before and after inversion.

As described above, the male winding 8 and the later-described chimaki 2
The reason why the reversing mechanism for reversing the warp T mounted between the warp T and the rear warp T via the front movable frame 4 and the rear movable frame 15 is provided is that the dyeing of the warp T by the printer device 26 described later is performed. The dye hardly penetrates into the inside and prints only on the surface, not on the back. Therefore, even with a slight twist rotation of the warp T, the Kasuri pattern is broken and becomes unclear. For this purpose, it is necessary to reverse the warp yarn T and print the Kasuri pattern on the back surface.

Reference numerals 19 and 20 denote a pair of front and rear healds, and 21 denotes a reed. When winding a warp T on which a Kasuri pattern is printed on the aforementioned Chimaki 22, the weft is coarsely woven so that the printed Kasuri pattern is not displaced. It is for weaving. In the illustrated embodiment, the healds 19 and 20 and the reed 21
Although it is installed at the front position of the rear movable frame 15, it may be installed at the rear position of the front movable frame 4, and the latter is more preferable to prevent the printed kasuri pattern from shifting. .

Reference numeral 22 designates a thousand rolls for winding the warp T on which a Kasuri pattern is printed and then temporarily woven.
2 is installed at a lower position of the reed 21,
2 is supported by a support shaft 23 extending from both ends thereof to the outside of both side walls of the rear movable frame 15, and is installed so as to be rotatable with respect to the rear movable frame 15. It should be noted that, while the thousand winding 22 is detachable from the spindle 23, the spindle 23 is configured to rotate integrally with the thousand winding 22.

Reference numeral 24 denotes a take-up motor for driving the aforesaid winding machine 22, reference numeral 25 denotes a roll paper for preventing pollution, and the roll paper 25 for preventing pollution is rotatably mounted at a position behind the aforesaid winding machine 22. This is to prevent mutual contamination between the warp T immediately after printing and the warp T printed earlier and wound up in the 1,000 winding 22. Therefore, the roll paper unwound from the pollution prevention roll paper 25 is the same as that of the 1000 rolls.
It is wound together with the warp along the back side of the warp wound in 2, and inserted between the warp layers. In the drawings, OP is an operation panel.

Reference numeral 26 denotes an ink jet printer for dyeing a kasuri pattern on the warp T. The printer 26 is arranged on the side of the opening 3A of the space 3 in the warp kasumi pattern dyeing apparatus 1.
On the table 27 of the printer device 26, a Y-axis traveling portion 28 is fixed on one side thereof in parallel with the longitudinal direction of the gantry 2, and the slide shaft 29 of the Y-axis traveling portion 28 is fixed.
Is connected to the X-axis traveling unit 30 so as to be slidable in the Y-axis direction.

The slide shaft 3 of the X-axis traveling unit 30
1, a cassette holder of four ink cassettes 32 is slidably connected in the X-axis direction, and yellow, magenta, cyan, and black inks are stored in the ink cassettes 32, respectively. Here, the printer device 26 operates based on the original Kasuri pattern data stored in the computer in advance.

Although not shown, the printer 26 is provided with a charge-coupled device camera (CCD camera) connected to a computer for recognizing a print start position. This is because the center in the width direction of the warp T mounted between the male winding 8 and the 1,000 winding 22 and its rotation center (the front portion) for inverting the center through the front movable frame 4 and the rear movable frame 15. The movable shaft 5 does not always coincide with the rear movable shaft 16).
Therefore, when the warp T is reversed, it is not necessarily reversed to the same position, and there is a possibility that the warp T is slightly displaced. In order to print the Kasuri pattern on both the front and back surfaces of the warp T, as shown in FIGS. It is necessary to perform pattern matching between the print on the front side and the print on the back side.

That is, the pattern matching is performed as shown in FIGS.
As shown in A, the intersection of the right end of the warp T before the reversal and the print start line L is A, the intersection of the left end of the warp T and the print start line L is B, and the position of the intersection A when printing on the surface of the warp T Is recognized by a CCD camera. Then, when printing the back side of the warp T after printing the front side, the warp T is reversed left and right, and the position of the intersection B is
Recognize with CD camera. The misalignment between the intersection A and the intersection B is measured by a computer and is displayed on a monitor in dot units. Based on the measured data, the printing start point on the back surface of the warp T is corrected, and thereafter printing is performed.

Next, the operation of the above embodiment will be described. First, the warp threads T are arranged in parallel in the number required for the weaving width dimension and wound around the male winding 8, and the other end is wound on the heald 2
1 and 22 and the reed 23 and fixed to the 1,000 winding 22 are set in the warp kasuri pattern dyeing apparatus 1. Then, when the winding motor 24 is operated to slightly rotate the 1,000 winding 22 in the winding direction, a predetermined brake is applied to the male winding 8 by the warp tension adjusting mechanism 10. Warp T mounted between Omaki 8 and Chimaki 22
Is applied with the same amount of tension as in the loom.

Next, as shown in FIG. 5, the warp kasuri pattern dyeing device 1 is moved toward the printer device 26, and the printer device 26 is set in the space 3 from the opening 3A. As a result, as shown in FIGS. 1 and 6, the warp T is
7 and the ink cassette 32. At this time, the left and right corners of the table 27 are aligned with the positioning portions P of the gantry 1.
1 and P2 for positioning.

Therefore, when the printer 26 is operated via a computer, the ink cassette 32 reciprocates in the X-axis direction according to the kasuri pattern data, and moves forward to move a predetermined kasuri pattern on the surface of the warp T. Is printed.
When the printing of the Kasuri pattern on the surface of the warp is completed,
As shown in FIG. 7, after pulling out the warp kasuri pattern dyeing device 1 from the printer device 26, the front and rear reversing motors 7, 18 are used.
Operate. Thereby, the front movable frame 4 and the rear movable frame 1
5 is a front movable shaft 5 and a rear movable shaft 1 as shown in FIG.

° Synchronous rotation, then horizontal.

After the warp T is turned over, as shown in FIG. 9, the warp kasuri pattern dyeing device 1 is moved again in the direction of the printer device 26, and the back surface of the warp T is scanned by the CCD camera as described above. After the correction of the printing start point, a reverse Kasuri pattern (mirror pattern) opposite to the Kasuri pattern printed on the front surface is also printed on the back surface of the warp T.

When the printing on the front and back surfaces of the warp T is completed, the weft is coarsely woven into the warp T to prevent temporary displacement in order to prevent the warp T from shifting. That is, FIG.
As shown at 0, the foot pedals F1 and F2 are alternately depressed to move the healds 19 and 20 up and down alternately, thereby forming a space (a shed) between the odd and even sets of two warps T. . Then, after a weft (not shown) is passed through the shed, beating is performed by the reed 23. This temporary weaving may be performed before printing on the warp T as described above.

The temporarily woven warp T is taken up by a winding motor 2.
The reels are sequentially wound around the 1,000-turn 22 rotating at 4. At this time, between the warp T to be newly wound up and the warp T already wound up, as shown in FIG. 10, the pollution preventing roll paper 25 is inserted and wound up. This prevents contamination of the previously wound warp T. Then, when the printing operation was completed, the male winding 8 was removed from the front movable frame 4 and the thousand winding 22 was removed from the rear movable frame 15, and these were installed on a loom. Warp T
By carrying out the main weaving while paying out from No. 2, a Kasuri fabric dyed with a Kasuri pattern is obtained.

The positioning of the printer device 26 in the space 3 of the warp kasuri pattern dyeing device 1 is performed by positioning the left and right corners of the printer device 26 in front of the table 27 with the positioning portion P1 of the gantry 2. , P2. However, a rail is attached to the floor in the direction of the printer device 26, and the warp-kasari pattern dyeing device 1 is mounted along the rail so as to be able to travel freely. Warp kasuri pattern dyeing device 1
There is no need to position the camera every time it is moved.

Embodiment 1 FIG. 11 and FIG. 12 show a multicolor suture underlay K. Table 1 shows design data of the underlay K. The feature of this pattern is that the ancient rice Ryu Kasuri pattern is arranged in our production area in a modern style, and the background uses an abstract painting. The round pattern in the figure is an accent, and the entire pattern is given a gradation (blur) that was difficult with conventional Kasuri patterning. Also, an unclear Kasuri pattern printed on the front side alone and a clear Kasuri pattern printed on the front and back sides were mixed. The print position of the pattern is lower than the item, so the upper and lower body, upper front body, upper front layer,
It was set so that the pattern would enter the warp threads that would be the right outer sleeve and the left inner sleeve.

[0031]

[Table 1]

The ink is subjected to full-color printing using four colors of acid dyes, yellow, magenta, cyan, and black. In addition, since there is a risk that the pattern may be deformed due to the weaving shrinkage ratio during weaving, the shrinkage ratio in the vertical and horizontal directions due to the trial weaving is calculated, the Kasuri pattern is enlarged in advance corresponding to them, and the pattern is used as warp. Printed. After weaving, it was kept in steam at 100 ° C. for 20 minutes to fix the dye.
Excess dye was removed by treating with a soaping agent for preventing acid dye white spot contamination at 50 ° C. for 10 minutes, followed by washing with water and drying.
