DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic furrowing apparatus and a furrowing method using the same, and more particularly, to a process for preparing a weaving in which a warp and a weft are interlaced to weave a fabric. Automatic ridge removal device capable of automatically performing ridge removal while arranging a plurality of types of warp yarns having different types in a desired order, and a method for reliably performing ridge removal using such a device This is very useful for producing high value-added fabrics in which different types of yarns are arranged in the warp.

[0002]

2. Description of the Related Art As is well known, a process of manufacturing a woven fabric includes a weaving process of weaving a woven fabric by interlacing a warp and a weft and a preparation process necessary for this weaving. The preparation process includes the work processes of warp preparation and weft preparation, and the warp preparation work includes repetition work, sizing work, warping work, ridge removal work, heald threading / reeding work, and machine work. is there.

[0003] Among the above-mentioned warp preparation operations, the ridge removal operation is performed by passing a plurality of parallelly arranged warp yarns through a ridge line from the lateral direction and sneaking the ridge line up and down between the warp yarns. In this ridge removal, the heald threading and reeding work in the subsequent process can be smoothly performed by the ridges alternately passed above and below each warp. However, the ridge-removing work is a precise and detailed work in which hundreds or thousands of thin yarns are taken out of warps arranged in parallel in a state of intertwining one by one, and the ridges are passed up and down. Therefore, there is a problem that it is very difficult and troublesome for even a skilled person to perform such work manually.

[0004] Therefore, there has been proposed a ridge removing machine for mechanically performing the ridge removing work as described above.
It is composed of a warp take-out means for selecting and taking out any one of a number of warps indiscriminately, and a ridge string passing means for passing a ridge string between these warps. This makes it possible to automatically take out an arbitrary one of a large number of intricately entangled warps and automatically perform ridge removal.

[0005] However, in the above-mentioned ridge removing machine, since one arbitrary warp is selected and taken out indiscriminately, plural kinds of yarns having different colors and thicknesses are used for the warp. In such a case, there is a drawback that it is not possible to take out the warp yarns in order for each type and to perform ridge removal in a desired arrangement. For this reason, the above-mentioned rowing machine was not useful for producing a high-value-added fabric in which different kinds of warps were arranged in an orderly manner.

[0006]

After positioning the position 11 substantially at the center of each thread sheet, the guide tube 31 forming the insertion path for passing the ridge L is raised to the opening H. Next, the ridge L is guided by the injection nozzle 32 into the guide tube.
After inserting the guide tube 31, the guide tube 31 is lowered. Then, the first ridge cord L is inserted into the opening H formed by each warp. Thereafter, all of the first split rod 21 _first to fourth dividing rods 21 ₄ back from the bottom of the rod receiving portion 23 'at the top of the rod receiving portion 23, wound by the respective yarn sheet is advanced slightly loom beam b side take.

When the second warp string L is inserted by performing the warp sorting operation and the warp string inserting operation again as described above, the pair of warp strings LL are alternately passed as shown in FIG. The ridge is removed in a state where the ridge is removed, and the ridge removal work is completed. In this case, the order of the left and right movement of the lead 11 in the warp sorting operation is left, right, left, and right, which is opposite to the first movement order of the lead 11 (right, left, right, left).

What should be particularly noted in the above ridge removing operation is that the split rod 21 is moved closer to the vicinity of the lead 11 along the longitudinal direction of the thread sheet S and is moved downward. As a result, the thread rod S is handled at a steep angle by the split rod 21, and each warp W of the thread sheet S is
Will be pushed down to the hook part 11a or the valley part 11b,
As a result, it is possible to greatly improve the reliability of the warp handling as compared with the related art.

Finally, an example in which the mechanism for moving the lead 11 back and forth and the tilting mechanism are added to the above-described embodiment will be described with reference to FIGS. 14 and 15. As shown in FIGS. 14 and 15, between the lead 11 and the loom beam b, a pair of left and right guide shafts 15, 15 parallel to the longitudinal direction of the thread sheet S, and parallel to the width direction of the thread sheet S. Guide shaft 16 and the pair of guide shafts 15

17 and a pair of left and right driving units 18 and 18 each composed of a servomotor for rotating each of the feed shafts 17 and 17. When these paired servo motors are driven, the lead 11 moves backward on the pair of guide shafts 15 toward the loom beam b as shown in FIG. Lead 11 in this way
Can be moved back and forth along the longitudinal direction of the thread sheet S, the lead 11 can also be used as a front reed at the time of warping work, and the lead 11 can be effectively used.

When only one of the servo motors is driven, one end of the lead 11 moves backward on the driven guide shaft 15 toward the loom beam b, and the other end of the lead 11 The lead 11 is slid on the shaft 16 and the lead 11 is arranged obliquely with respect to the thread sheet S as shown in FIG. Thereby, the winding width of the yarn sheet S on the loom beam b can be reduced, and the winding width can be changed by changing the inclination angle of the lead 11 as necessary.

Although the embodiments of the present invention are substantially as described above, the present invention is by no means limited to the above-described embodiments, and various modifications are possible within the scope of the claims. For example, for example, the split rod of the present embodiment
At 21, the yarn sheet S moves in the longitudinal direction (lead 11
) And then move it down. However, moving the split rod 21 down and then moving it in the longitudinal direction, or moving it closer to the lead 11 while oscillating it obliquely, etc. It is also possible to program various two-dimensional motion patterns and select and apply the optimal two-dimensional motion pattern to the target warp W,
It goes without saying that such changes also belong to the technical scope of the present invention.
