Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method and apparatus for inserting a weft rod between warp rods in a rod-type three-dimensional multi-shaft loom.

[Prior Art] The present inventors have previously disclosed, in Japanese Patent Application No. 63-249517, etc., a three-dimensional multiaxial fabric in which rods formed by bonding fiber bundles through a matrix are oriented in multiaxial directions. We are making proposals.

In the case of such a rod-type three-dimensional fabric, where each rod is a triaxial fabric in which the rods are orthogonal to each other, between the rods in a large group of longitudinal rods arranged in parallel, there are other latitudinal rods in two orthogonal axial directions. The weaving can be carried out by sequentially inserting the rods forming the group. When inserting this latitudinal rod group, a large number of rods that make up the latitudinal rod group are arranged in parallel in a plane orthogonal to the longitudinal rod group, and they are inserted all at once between the rods of the longitudinal rod group. Then, the latitudinal rods in the direction orthogonal to the latitudinal rods may be arranged, and they may be inserted all at once between the rods of the longitudinal rod group. That is, the rods for one cycle of textile structure in the warp rod group inserted from one direction can be arranged in a plane and inserted between the warp rods at once.

However, three-dimensional fabrics with four or more axes have the following problems. That is, FIGS. 4 and 5 show the structure of a three-dimensional, four-axis fabric, and in particular, FIG. 5 shows a structure in which a group of latitudinal rods 52 are oriented from three directions inclined with respect to a group of longitudinal rods 51 arranged in parallel. The three-dimensional four-axis fabric 50 that is inserted is shown in the insertion direction of one latitudinal rod group 52, and as can be seen from this figure, the longitudinal rod group 51
The openings/rods 52a, 52b, S2 for one cycle of the textile structure of the weft direction rod group 52 inserted from one direction
c, S2d, 52e or 52a, S2b, S2c
', S2d', 52e' are a plurality of parallel planes Pl, Pz that are slightly shifted in the weaving direction in the warp direction orad group 5,
Alternatively, it is within one plane P that is in a complicated inclined state with respect to the group of longitudinal rods 51. Therefore, the rods for one cycle of the textile structure of the weft rod group 52 inserted from one direction into the warp rod group 51 are inserted into the warp rod group 51 in the same way as in the case of the three-dimensional triaxial fabric. If it is attempted to insert the rods all at once, the construction and manufacture of the weft rod insertion device in the loom will become very complicated unless the support surfaces of the weft rods and throat groups to be inserted have different heights for each rod.

[Problems to be Solved by the Invention] The technical problem of the present invention is to simplify the device for inserting the weft rods in the three-dimensional multiaxial fabric, and in particular to arrange the weft rods to be inserted. The purpose of this invention is to simplify the device for inserting the latitudinal rod by making the support surface a plane with a simple orientation.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the rod insertion method for a rod-type three-dimensional multiaxial fabric of the present invention includes a method for inserting a weft direction rod into a rod-type three-dimensional multiaxial fabric having four or more axes. , one cycle of the textile structure of a group of weft rods inserted from one direction is perpendicular to a plane parallel to both the warp rods and the weft rods, and parallel to the plane containing the weft rods. An insertion device that can be arranged in an array and sequentially move the arranged latitudinal rods relative to each other in the axial direction of a group of longitudinal rods, and can be inserted separately at a plurality of positions corresponding to the insertion portions of the latitudinal rods between the longitudinal rods. According to the above l
This method is characterized in that necessary latitudinal rods are selectively inserted from among the latitudinal rods for a cycle.

Furthermore, the rod insertion device for a rod-type three-dimensional multiaxial fabric of the present invention is a device for inserting a weft rod into a rod-type three-dimensional multiaxial fabric having four or more axes. A rod support surface for arranging one cycle of the textile structure of the rod group is installed in a plane that is perpendicular to a plane parallel to both the longitudinal rod and the upper and the upper latitudinal rods, and that includes the latitudinal rods. , the support surface of this latitudinal rod is made relatively movable in the axial direction of the longitudinal rod group,

Although it is inclined depending on the structure of the multiaxial fabric to be woven, it is installed in a plane that is perpendicular to a plane parallel to both the warp rod and the weft rod and includes the weft rod.

In order to insert the weft rods supported by the rod support surface 16 between the warp rod groups 1, they must be successively moved in the weaving direction in the warp rod groups 1 and held at appropriate weaving positions. This movement may be carried out by raising and lowering the holding means for the transverse rod group 1 using the feed screw 12 as described above, but it is also possible to raise and lower the rod insertion device 15, and in any case, both of the holding means for the transverse rod group 1 may be moved up and down by the feed screw 12. It is only necessary to make it relatively movable in the axial direction.
