[0006]
(Function and effect)
By printing the warp yarn with an ink jet printer, the number of colors to be selected is not limited, and various designs such as warp and slanting blur can be printed, resulting in an abundant design. By weaving the weft yarn on the printed warp yarn group thereafter, a woven fabric having a three-dimensional feeling different from the one printed on the whole is obtained. At this time, not only a single color as a warp, but also a knitted fabric of an unprecedented design can be obtained by devising the use of the color of the warp. For example, weaving monochromatic or multicolored weft yarns with stripes or patterns on a group of warp yarns with a blur or gradation, and the color scheme and pattern of the weft yarns are combined with the design of the warp yarn group, making it complicated. It is possible to obtain a woven fabric having a novel design and texture as compared with conventional prints and patterns.
Here, the printing by the head of the ink jet printer has a limited printing area, and in order to obtain a long object, it is suitable to perform the movement of the head according to the present invention and the repeated printing and weaving.
It is not impossible to keep the printing and weaving continuous by synchronizing the printing speed of the printer and the weaving speed of the loom, but the warp yarn tension from the loom side during the operation varies over time. It is effective to separate the operation of the loom and the printing to prevent fluctuations in tension during printing, and to allow various fine-tuning stages. is there.
Further, even if the mark print is performed on the lateral end of the warp yarn group, the portion is not used, and therefore there is no problem for the woven product. Further, since the mark printing is performed together with the printing on the main body of the aligned warp yarn group, it is possible to directly detect the print length by detecting the print mark with a sensor. . Although it is possible to detect the warp yarn feed movement length during weaving, the warp yarn moves about 1 cm when weaving the weft yarn during weaving, so it is possible to detect the exact warp feed movement length. It is also based on the knowledge that it is difficult.
In particular, according to the present invention, as described later, it is possible to accurately link the print length and the warp feed moving length by weaving.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a conceptual diagram of the present invention. Warp yarn X having a desired length is warped from cheese 1 and set on a delivery roll (beam, male winding) 2. Reference numeral 3 denotes a loom for weaving warp yarn X and weft yarn Y such as a jacquard loom equipped with a jacquard 3a. The inkjet printer 4 faces the surface where warp yarn groups are aligned in parallel upstream of the loom 3. The head 4a is disposed. The weft Y can be supplied directly by the shuttle 3b in the case of a shuttle loom, or directly by the cheese 3c in the case of a high-speed loom such as a rapier loom, and is not limited to the supply of loom and weft and the weaving form. .
[0012]
Printing on the warp while moving the head 4a in the lateral direction, and then moving the head 4a to a position different in the warp direction, and printing on the warp while moving the head 4a in the lateral direction at that position. Is repeated.
[0013]
After the repetition of printing is completed with a certain length in the warp direction, the loom 3 is operated and weaved. When the weaving of a predetermined length is completed, the loom 3 is stopped, and printing is resumed instead. Finally, the fabric after weaving is taken up as a wound fabric 5.
[0014]
As a specific example of the apparatus, reference is made to the drawings after FIG. That is, from the upstream side, the warp yarn feeding device 10, the ink jet printer printer 4 and the printer feeding device 20, the optical sensor 30 (for example, a color sensor) as a warp yarn feeding amount (weaving amount) detecting means, and the warp yarn after printing provided as necessary. Feeding surface adjusting means (not shown) for adjusting the vertical height position of the group alignment surface, and the loom 3 are provided.
[0015]
Since the known warp yarn feeding device 10 can be used, the description thereof is omitted.
[0016]
The peripheral device of the ink jet printer 4 in the embodiment is mounted on a pair of left and right mounts 6 and 6, and the head 4 a is mounted on a transverse drive guide means 7 straddling the main body portions 4 b and 4 b on the mounts 6 and 6. It can be moved laterally along. This lateral movement is basically the same as the driving means of the head of the impact dot printer, and is performed by an equipped drive motor (not shown). Accordingly, the transverse drive guide means 7 constitutes a lateral movement means of the head of the present invention.
[0017]
The pair of left and right mounts 6 and 6 are placed on a pair of left and right slide rails 21 and 21 installed with respect to the base, and the mounts 6 and 6 further include forward and backward advance rods 22 such as a feed ball screw. 22, feed pulleys 23, 23 are integrated at the ends of the forward / reverse feed rods 22, 22, respectively. Both the feed pulleys 23, 23 are wound around the output shaft of one servomotor 24. They are connected by hooked timing belts 25, 25. These elements constitute the longitudinal movement means of the present invention.
[0018]
Therefore, the forward and reverse rotation of the servo motor 24 causes the feed pulleys 23 and 23 and the forward and backward advance rods 22 and 22 to rotate via the timing belts 25 and 25, for example, so that the forward and backward advance rod 22 is used as a feed ball screw. Accordingly, the leg portions 6A of the mounts 6 and 6, which are screwed together, move forward and backward on the slide rails 21 and 21.
[0019]
The lateral movement means (configured with the transverse drive guide means 7 in the embodiment) of the head 4a and the longitudinal movement means (configured with the printer feeding device 20 in the embodiment) of the head are a printer. The drive means are configured so that they operate independently and the transversal movement means is activated after the lateral movement is completed.
[0020]
On the other hand, as shown in the drawing, warps (leads) 8 and 8 for passing warp yarns are provided before and after the head 4a. For example, it is desirable that the length (lead) 8 is 90 (whale size) and that four warp threads are put in one eye (about 0.4 mm) so that the warp threads do not overlap during printing.
[0021]
As the warp feed amount (weaving amount) detecting means, in order to detect the warp feed amount by actual weaving, printing on the main body on the surface where the warp yarn groups are aligned in parallel by the head 4a of the ink jet printer 4; At the same time, the print mark is printed with the warp length also present at the lateral end of the warp yarn group, and the print mark is detected by the optical sensor 30 supported on the main body 4b via the support member 30a. To.
[0022]
(About operation)
In the present invention, the head 4a of the ink jet printer 4 disposed opposite to the surface in which the warp yarn groups are arranged in parallel upstream of the loom 3 for weaving the warp and weft yarns is moved while moving in the lateral direction. Next, the head 4a is moved to a different position in the warp direction, and printing is performed on the warp yarn X while moving the head 4a in the lateral direction at that position.
[0023]
Specifically, the warp yarn is printed in the horizontal movement process of the head by the horizontal movement means (transverse drive guide means 7), and when the movement of the predetermined width in the horizontal direction is completed, the warp is completed. The direction moving means (printer feeding device 20) is actuated to move the head 4a to the next different position in the warp direction, and to print on the warp yarn while moving the head 4a laterally at that position. Repeatedly, when the print length in the warp direction becomes a predetermined length due to the repetition, the printer driving means is stopped.
[0024]
The loom 3 is operated after the printer driving means is stopped, the warp feed length associated with the weaving is detected by the warp feed length detecting means (optical sensor) 30 and the weaving of a predetermined length is completed. At this point, the operation of the printer driving means is resumed.
[0025]
On the other hand, the operation of printing and weaving will be described with reference to FIG. Process A is a stage in which weaving in the previous step is completed, the loom 3 is stopped, and printing is resumed. The head 4a stands by in a state where it is positioned at the weaving end position. Process B shows a stage where printing is resumed and printing is completed while printing the print mark PM. The head 4a performs printing while traversing during the backward movement of the traversing drive guide means 7. At this time, the optical sensor 30 also moves backward. Step C shows a stage in which the optical sensor 30 moves to the standby position in Step A, that is, the weaving end position after the head 4a moves to the head origin after the printing is completed. Process D shows the stage which starts weaving and moves after we move. With the weaving, the rear end position of the print mark PM advances. Process E shows a stage where the optical sensor 30 detects the trailing edge of the print mark PM. When the rear end of the print mark PM is detected, the operator of the loom 3 is notified by the display means or the like, and the weaving is finished. Step F shows a stage where the head 4a has moved to the weaving end position and is waiting for the start of printing. This standby stage is the process A of the next step. In this way, printing and weaving are performed while the steps A to F are repeated for each step.
According to such a form, the head 4a can be matched with the end position of weaving for each step. Therefore, continuity of printing can always be ensured.
[0026]
(Other matters)
In the above example, the ink jet printer 4 is connected to an image processing apparatus such as a computer, and a color signal for the warp yarn having a predetermined design is given to the ink jet printer 4. This color signal is a color signal corresponding to the lateral and warp positions of the warp X group. Since printing is performed by the inkjet printer 4, complicated dyeing is possible. Blur dyeing is also possible. As a matter of course, the weft thread may be a single color or a plurality or multiple colors. In the latter case, weaving with a more complex design is possible.
[0027]
Weaving can be plain weaving, oblique weaving, satin weaving, and these modified weaving, but satin weaving and its weaving are particularly desirable in order to give a sense of complexity and luxury.
[0028]
In the above example, the entire inkjet printer 4 is moved sideways and left and right. However, the head and the main body can be separated, and only the head can be moved sideways and left and right.
[0029]
If necessary, an ink drying means can be provided on the exit side of the ink jet printer 4.
[0030]
【The invention's effect】
As described above, according to the present invention, the respective advantages of the post-dyed fabric and the pre-dyed fabric are utilized to the maximum, giving a high-class feeling due to the fineness, the depth of shade, etc. as the texture, the number of colors is free, and the gradation is Free, easy dyeing process and low cost.
