As a result, the weft 2 adjusted to a predetermined tension is pulled out from the lower end 12A of the weft nozzle 12, and the weft nozzle 12 is installed at a predetermined position on the rear frame 1D side of the weft frame 1. deep.

An example is shown in which the weft nozzle 12 reciprocates from the right side to the left side and from the left side to the right side of the weft frame 1, and stretches the weft 2 in a state aligned with the weft frame 1. Referring to FIG. 7, first, FIG.
As shown in (a), the weft nozzle 12 is moved from a stop position 50 mm from the locking needle 3 on the right side frame 1B to a Z position (not shown).
Increase by 20mm due to the operation of the shaft air cylinder, 80mm
When it moves to the right stop line R and stops by the operation of a photomicrosensor (not shown), it moves down to the position shown by the broken line by the operation of the Z-axis air cylinder.

Here, when the weft nozzle 12 is stopped to descend as indicated by the broken line, the lower end 12A of the weft nozzle 12 is located slightly above the upper surfaces of the left and right side frames 1A and 1B. Next, the weft nozzle 12 moves to the left stop line L 30 mm before the locking needle 3 on the left frame 1A of the weft frame 1 in the lowered position and stops. Then, it rises by 20 mm by the operation of the Z-axis air cylinder, moves to the left by 80 mm and stops.

The stopped weft nozzle 12 is lowered by 20 mm by the operation of the Z-axis air cylinder, and stops at the position shown in FIG. At this time, as shown in FIG.
Descends while being guided by the front end face 21B of the weft insertion guide 21.
A is securely inserted between the front and rear locking needles 3.

When this state is reached, the weft holding pin 1
9 moves forward by the operation of the Y-axis air cylinder 19A, and FIG.
As shown in (c), it stops just above the weft 2 located on the upper surface of the left frame 1A. As a result, the weft 2 is suppressed from above by the weft holding pin 19, and cannot be moved upward.

In this state, the weft frame 1 is moved together with the intermittent moving table 7 by one pitch (the distance between the locking needles 3 and 3).
When it moves backward only intermittently, as shown in FIG.
The lower end 12A of the weft nozzle 12 in the lowered state is located between the locking needles 3, 3 immediately before the locking needles 3, 3 in which the weft 2 has already been inserted. Next, the weft nozzle 12
After raising by 20mm by the operation of the shaft air cylinder,
As shown in FIG. 7 (e), it moves to the right by 80 mm and stops above the left stop line L.

Then, as shown in FIG. 7F, after the weft nozzle 12 stopped above the left stop line L is lowered by 20 mm by the operation of the Z-axis air cylinder, the weft holding pin 19 is moved to the Y-axis air position. It is retracted by the operation of the cylinder 19A. As a result, the weft 2 is released from the holding by the weft holding pin 19, and is caught by the locking needle 3 on the left frame 1A. Inserted between the needle 3 for use and the lock needle 3 immediately before.

Further, the weft nozzle 12 which has stopped descending at the left stop line L remains in the right frame 1 of the weft frame 1 in that state.
B: Stops after moving to the right stop line R of 30 mm before the locking needle 3. Then, it rises 20 mm by the operation of the Z-axis air cylinder, moves to the right by 80 mm, and stops. The stopped weft nozzle 12 is lowered by 20 mm by the operation of the Z-axis air cylinder. At this time, as described above, the weft 2
Is lowered while being guided by the front end face 21B of the weft insertion guide 21, and the weft 2 is reliably inserted between the front and rear locking needles 3 from its lower end 21A.

When this state is reached, the weft holding pin 19 advances by the operation of the Y-axis air cylinder 19A and stops just above the weft 2 located on the upper surface of the right frame 1B. It is suppressed from above by the weft holding pin 19 and cannot be moved upward. Further, after the weft nozzle 12 is raised by 20 mm, it is moved to the left and stopped at the right stop line R for 20 mm. By descending, the weft 2 is caught on the locking needle 3 on the right side frame 1B and inserted between the locking needles 3 and 3, and the other operations are the same as in the above case.

In this manner, the weft 2 is alternately locked by the locking needles 3 of the weft frame 1 by repeating the reciprocating operation of the weft nozzle 12 in the left-right and up-down directions. It is stretched in a state where it is aligned along the front-back direction.

Next, means for dyeing a pattern on both the front and back surfaces of the weft 2 stretched on the weft frame 1 as described above will be described with reference to the embodiment shown in FIGS. In the figure, reference numeral 22 denotes an ink jet type printer. A Y-axis traveling unit 24 is fixed to one side of a table 23 of the printer 22 in parallel with the longitudinal direction of the table 23. An X-axis traveling unit 27 is slidably connected to the 24 slide shafts 26.

A cassette holder for a plurality of ink cassettes 29 is mounted on a slide shaft 28 of the X-axis traveling portion 27.
The ink cassette 29 stores inks of different colors such as yellow, magenta, cyan, and black.
Here, the printer device 22 operates based on the original design data stored in the computer in advance.

Reference numeral 30 denotes a case where a pattern is dyed on the weft 2 stretched on the weft frame 1 by the printer device 22.
A frame holding frame for holding the weft frame 1, a pair of support columns 31, 31 which are wider than the left and right width of the weft frame 1 and are separated from each other.
Are arranged on the front and rear sides, respectively, and running rails 32, 32 are fixed on the upper portions of the front and rear support columns 31, respectively, in a parallel and horizontal state.

Here, the pair of running rails 32, 32
Is set wider than the front-rear width of the weft frame 1, and the right end of the running rail 32 extends from the right side of the support column 31 longer than the left-right width of the weft frame 1. I have. On the opposing surfaces of the front and rear running rails 32, holding portions 33 for holding the front and rear side frames 1C and 1D of the weft frame 1 can be freely moved by a support shaft 34 having its center of symmetry axis, and a support shaft 34. It is installed so that it can rotate around.

The height of the frame holding frame 30 is adjusted so that the extension 32A of the traveling rail 32 is inserted between the upper surface of the table 23 of the printer 22 and the lower surface of the X-axis traveling portion 27 without contact. When the height is set to the height, the frame holding frame 30 is movable by casters 35 provided at the lower end of the support column 31.

Next, a description will be given of a dyeing operation for dyeing a pattern pattern on the weft 2 stretched on the weft frame 1 by the printer device 22. First, the front and rear sides of the support column 31 of the frame holding base 30 will be described. The front and rear side frames 1C, 1D of the weft frame 1 are fixed to the holding portions 33, 33, respectively, and the weft frame 1 is held in a horizontal state (shown by dotted lines in FIG. 8). Next, the frame holding gantry 30 is moved, and the right side of the support column 31 is installed on the left side of the printer device 22. Position.

At this time, the support shafts 34 of the front and rear holding parts 33
Is arranged so as to be orthogonal to the X-axis traveling portion 27 of the printer device 22. Then, the weft frame 1 sandwiched between the holding portions 33 is moved to the extending portion 32A of the traveling rail 32, and the upper surface of the table 23 of the printer device 22 is moved to X.
It is fixed between the shaft running portion 27 and the lower surface.

When the printer 22 is operated via a computer, the ink cassette 29 moves in the X-axis direction according to the pattern data, and moves forward to form a predetermined pattern on the surface of the weft 2 by the ink jet method. Printed by. When the printing of the surface of the weft 2 is completed, the weft frame 1 is moved to the running rail 32.
After moving to the support 31 side through the
4, the weft frame 1 is again moved to the extending portion 32A of the running rail 32, and the reverse of the weft 2 is the same pattern as the pattern printed on the front surface (mirror surface). Pattern).

The reason why the weft frame 1 is turned over and printed on both the front and back surfaces of the weft 2 is that when printing only on the front surface, the ink hardly penetrates into the inside of the yarn, deep dyeing cannot be performed, and the yarn cannot be dyed. If ink is excessively adhered to penetrate the inside or the back surface, bleeding occurs due to a capillary phenomenon. Therefore, the pattern does not become clear. When a reverse pattern (mirror pattern) which is the same as the pattern on the front surface and is printed on the back surface of the weft yarn 2, it is natural that the front and back pattern patterns are matched so that there is no color pattern shift.

As described above, the present invention has the above-mentioned structure. (1) It is possible to mechanize and automate the weft pattern dyeing work which has been manually performed so far, and does not require a skilled engineer. Therefore, significant labor saving is possible. (2) A variety of pattern dyeing such as a multicolored kasuri pattern and a blurred kasuri pattern, which have been difficult in the past, can be performed, and can be developed into a differentiated product with high added value. (3) By printing on both the front and back sides of the weft, it is possible to display a clear Kasuri pattern even when the weft is twisted and rotated, and there are various effects that deep dyeing becomes possible. .
