On the other hand, the present invention relates to a beating method and apparatus for a three-dimensional multi-axis woven fabric loom having four or more axes in which weft rods are inserted from at least a plurality of tilt directions that are not parallel or perpendicular to the warp rod group.

[Prior Art] A rod type three-dimensional triaxial woven fabric is woven by inserting weft direction rods from two directions orthogonal to each other to a large number of warp direction rods arranged in parallel. In a weaving machine for weaving such a three-dimensional three-axis fabric, since all the latitudinal rods to be inserted are arranged in parallel, the latitudinal rods provided with a large number of holes for inserting the respective longitudinal rods are used to sequentially insert the latitudinal rods. It is possible to perform a beating.

However, in the three-dimensional multiaxial fabric having four axes or more as shown in FIGS. 1, 7, and 8, the weft direction rod groups inserted from a plurality of directions with respect to the warp direction rod group are not parallel to each other. However, it cannot be beaten by the above-mentioned reeds because it has a complicated slanting projection, and some kind of reeding means was developed to obtain a three-dimensional multiaxial fabric with high density insertion of the weft direction rod. Had to do.

[Problems to be Solved by the Invention] The present inventors actually weaved a three-dimensional multiaxial woven fabric using rods, and as a result of observing the properties of the woven fabric in detail, the longitudinal direction of the inserted latitudinal rod It was confirmed that repulsion was possible by pressing the part protruding outward from the rod group in the axial direction of the longitudinal rod group. This is 4
In a three-dimensional multiaxial woven fabric with axes or more, the weft direction rods inserted from a plurality of directions between the warp direction rods are in a state of being combined with each other, and even if a part of the weft direction rods is pressed, the weaving state is It is thought that this is because it does not easily collapse, and this tendency is particularly large when the arrangement state of the longitudinal rod groups is fixed and the latitudinal rods are densely inserted between them.

The present invention is based on such knowledge, and the technical problem thereof is that in a rod-type three-dimensional multiaxial woven fabric of four or more axes, it is possible to effectively beat, and the beating has a simple structure. To get the means.

[Means for Solving the Problems] A beating method according to the present invention for solving the above problems is directed to a large number of longitudinal rod groups set in advance in an array state.
At least in the weaving process of a rod-type three-dimensional multiaxial fabric in which weft rods are sequentially inserted from a plurality of slant directions that are not parallel or perpendicular to the warp rod group, the outer side of the inserted weft rods from the warp rod group The reciprocating member opposed to the protruding portion and the woven fabric that has already been woven are relatively moved in the axial direction of the warp direction rod group to reciprocate the inserted weft direction rod. is there.

Further, the repulsion device of the present invention is a holding means for a longitudinal rod group in which a large number of longitudinal rod groups can be set in advance, a relative movement in the axial direction of the longitudinal rod group, A rod-type three-dimensional multiaxial weaving loom including rod-inserting means for inserting a latitudinal rod from at least a plurality of tilt directions that are not parallel or perpendicular to the warp rod group, and a woven fabric already woven A reciprocating member that relatively reciprocates in the axial direction of the longitudinal rod group to beat the reciprocating rod group, and the repulsing member surrounds the longitudinal rod group and projects outward from the longitudinal rod group of the weft rod. Formed into a substantially ring shape facing each other, and its rod pressing surface is inserted into the latitudinal direction rods when the pressing of the latitudinal direction rods is completed after one cycle of the latitudinal direction rod insertion is completed. It is characterized in that it has shaped to strike the.

In the above-mentioned beating device, the beating member can have a function as a guide for the insertion weft direction rod.

[Operation] In the weaving process of sequentially inserting the weft direction rods into the warp direction rod group from a plurality of tilt directions and weaving the weft direction rods, the beating which opposes the part of the inserted weft direction rods protruding outward from the warp direction rod group. When the member and the already woven fabric are relatively moved in the axial direction of the warp direction rod group and the inserted latitudinal rod is beaten, the latitudinal rod group remains in its three-dimensional arrangement. The pitch between can be narrowed.

This is because in a three-dimensional multi-axis fabric having four or more axes, the weft direction rods inserted from a plurality of directions between warp direction rod groups are combined with each other, and for example, a part of the weft direction rods is warped. This is because even if the rod group is pressed in the axial direction, the weaving state does not easily collapse.

Therefore, in a three-dimensional multi-axis woven fabric having four or more axes, it is possible to effectively beat and obtain a beating means having a simple structure.

[Embodiment] FIGS. 1 to 3 show the construction of a three-dimensional multi-axis weaving loom equipped with a beating device according to the present invention, and FIGS.
