Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a method and apparatus for beating during the weaving process in a rod-type three-dimensional multi-axis textile loom, and in particular to The present invention relates to a beating method and apparatus for a three-dimensional multiaxial textile loom having four or more axes, in which weft rods are inserted from a plurality of oblique directions that are not parallel or perpendicular to at least a group of warp rods.

[Prior Art] A rod-type three-dimensional triaxial fabric is woven by inserting weft direction rods into a large number of longitudinal direction rods arranged in parallel from two mutually orthogonal directions. In machines that weave such three-dimensional triaxial fabrics, the weft-direction openings and ends to be inserted are all arranged in parallel. It is possible to beat the latitudinal rods.

However, in a three-dimensional multiaxial fabric with four or more axes as shown in Figure 1, Section 7, and Figure 8, the latitudinal rod groups inserted from multiple directions with respect to the warp rod group are not parallel to each other. However, in order to obtain a three-dimensional multiaxial fabric with high-density weft-direction rods inserted, some kind of reeding method was developed. I needed to.

[Problems to be Solved by the Invention] The present inventors actually weaved a three-dimensional multiaxial fabric using rods, and as a result of detailed observation of the properties of the fabric, the longitudinal direction of the inserted weft rod It was confirmed that reed beating was possible by applying pressure in the axial direction of the longitudinal rod group on the part that protruded outward from the rod group. This is 4
In a three-dimensional multiaxial fabric with more than one axis, the weft rods inserted from multiple directions between the warp rods are combined with each other, and even if a part of the weft rods is pressed, the weaving state cannot be changed. This is thought to be because they do not easily collapse, and this tendency is particularly strong when the longitudinal rod group is arranged in a fixed manner and the latitudinal rods are densely inserted between them.

The present invention is based on this knowledge, and its technical problem is to provide a method for effectively reeding a rod-type three-dimensional multiaxial fabric with four or more axes, and a simple structure for reeding. It's about getting the means.

[Means for Solving the Problems] In order to solve the above problems, the reed beating method of the present invention includes a method for reeding a large number of longitudinal rods set in advance in an array.
In the weaving process of a rod-type three-dimensional multiaxial fabric in which weaving is performed by sequentially inserting weft rods from a plurality of oblique directions that are not parallel or perpendicular to the warp rod group, the weft rods are inserted outward from the warp rod group. It is characterized by beating the inserted weft rods by relatively moving the beating member facing the protruding part and the already woven fabric in the axial direction of the group of warp rods. be.

In addition, the reed beating device of the present invention includes a longitudinal rod group holding means that can set a large number of longitudinal rod groups in a pre-arranged state, and a longitudinal rod group holding means that is capable of relative movement in the axial direction of the longitudinal rod group. A woven fabric that has already been woven in a rod-type three-dimensional multiaxial textile loom, which is equipped with rod insertion means for inserting weft rods into the rod group from at least a plurality of oblique directions that are not parallel or perpendicular to the longitudinal rod group. The reeding member is provided with a reeding member that moves relatively in the axial direction of the longitudinal rod group to beat the reeding member, and the reeding member is a part that surrounds the longitudinal rod group and protrudes outward from the longitudinal rod group of the latitudinal rod. The rod pressurizing surface is formed into a general ring shape facing the latitudinal rod, and its rod pressurizing surface is shaped so that it simultaneously hits the latitudinal rods when the insertion of the latitudinal rods ends after one cycle of latitudinal rod insertion. It is characterized by the fact that it has been formed.

In the above-mentioned reeding device, the reeding member can have a function as a guide for the inserted latitudinal rod.

[Function] In the weaving process in which weaving is performed by sequentially inserting weft rods into a group of warp rods from a plurality of inclination directions, a reed that faces the part of the inserted weft rod that protrudes outward from the group of warp rods. With hammered parts.

When the woven fabric that has already been woven is moved relative to the axial direction of the warp rod group and the inserted weft rod is beaten,
The pitch between the latitudinal rods can be reduced while maintaining the three-dimensional arrangement of the latitudinal rods.

This is because in a three-dimensional multiaxial fabric with four or more axes, weft rods inserted from multiple directions between groups of warp rods are combined with each other, for example, some of the weft rods are This is because even if the lot group is pressed in the axial direction, its woven state will not easily collapse.

Therefore, it is possible to obtain a beating means that can effectively beat a three-dimensional multiaxial fabric having four or more axes and has a simple configuration.

[Example 1] Figures 1 to 3 show the configuration of a three-dimensional multi-axis textile loom equipped with a beating device according to the present invention, and Figures 4 to 6
The figure shows the configuration of the reed beating member.

In the present invention, the fiber bundles used for manufacturing the three-dimensional multiaxial fabric are bonded in advance by a matrix to form a rod, and the rod thus formed is subjected to weaving as described below.

In the three-dimensional multiaxial textile weaving apparatus shown in FIGS. 1 to 3, a holding means 11 is provided on the machine frame 1O for holding a large number of the rods as a longitudinal rod group 1 in a parallel state at required intervals. , is supported by a feed screw 12 so that it can be raised and lowered, and a machine frame 1 is used to hold the upper part of the longitudinal rod group 1.
A perforated plate 13 is attached to 0.

The rod insertion device 15 for inserting the weft rod group 2 between the warp rod groups l has a rod support surface 16 for arranging one cycle of the textile structure of the weft rod group 2 inserted from one direction. There is. This rod support surface 16 is inclined according to the structure of the multiaxial fabric to be woven, but is perpendicular to a plane parallel to both the warp rod and the weft rod, and includes the weft rod. installed within a plane.

In order to insert the weft rods supported by the rod support surface 16 between the warp rod groups 1, they are sequentially moved relative to the weaving direction in the warp rod group 1 as weaving progresses, so that appropriate weaving can be achieved. Must be held in position. This movement may be carried out by raising and lowering the holding means for the transverse rod group 1 by 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.

Insertion bag N1 inserted between longitudinal rod group 1 by pressing one cycle of the latitudinal rods arranged on the support surface 16
5 is attached with a rod magazine 17 that sequentially supplies a group of weft rods 2 for one cycle of the textile structure onto the support surface 16. This rod magazine 17 has an opposing wall 18 in order to supply the latitudinal rod group 2 in a desired arrangement.
．． The weft direction rods 2a are fitted and held between the corresponding grooves 19 and 19 provided in the weaving grooves 18, respectively, and the weft direction rods 2a held in these corresponding grooves 19 and 19 fall naturally as weaving progresses. They are sequentially fed onto the rod support surface 16. The length of the latitudinal loft 2a held in each corresponding groove 19, 19 is adjusted depending on the shape of the three-dimensional multiaxial fabric to be woven.

In this three-dimensional multiaxial textile loom, a multiaxial textile 3 as shown in FIGS. 7 and 8 is woven. In such a three-dimensional multiaxial textile 3, weft direction rods inserted from one direction It is not possible to arrange all the rods for one cycle of the textile structure in a group in one plane on the support surface 16 and insert them between the longitudinal rods at once.

That is, as shown in FIG. 8, in the three-dimensional four-axis fabric 3 in which the weft rod groups 2 are inserted in three inclined directions relative to the longitudinal rod groups 1 arranged in parallel,
When viewed from the insertion direction of one weft rod group 2, the rods 2A, 2B, 2C, 2 for one cycle of the textile structure of the weft rod group 2 inserted into the warp direction rond group l
D, 2E or 2A, 2B, 2C'.

2D' and 2E' are in a plurality of parallel planes p, , p, which are slightly shifted in the weaving direction in the warp rod group 1, or in a complex inclined state with respect to the warp rod group l. It lies within the plane P. Therefore, if you try to insert the rods for one cycle of the textile structure of the weft rod group 2 into the warp rod group 1 at once into the warp rod group 1, the rods in the weft direction The structure and manufacture of the weft direction rod insertion device in the loom become very complicated, such as by adding height differences for each rod to the support surface of the rod group.

Therefore, as can be seen from FIGS. 2 and 3, in the insertion device 15 for the latitudinal rod group 2, the latitudinal rods 2a located within the plurality of planes p, , p in FIG. Then, the bushing rod for press-inserting the latitudinal rod is divided, and these split bushing rods 20a,
20b are individually attached to drive members 21a and 21b. These driving members 21a.

21b is slidably disposed on a sliding table 22 provided on the machine frame 10, and is independently pushed and driven in the insertion direction of the weft direction rod 2a by a drive device (not shown) such as a fluid pressure cylinder. The bushing rod 20a of the drive member 21a located far from the longitudinal rod group 1 is slidably passed through the drive member 21b of one example of the longitudinal rod group.

A fabric guide 24 arranged on the machine frame 10 so as to surround the woven three-dimensional fabric 3 guides the fabric 3 and at the same time prevents the matrix 4 impregnated into the fabric 3 from leaking out. It forms an impregnated part, and an injection pipe 27 for injecting the resin constituting the matrix is opened in the upper part of the part, and the textile guide 24 itself has a tapered shape at the bottom in consideration of curing shrinkage of the matrix. A heater 25 for heating the matrix 4 is provided around the matrix.

In addition, in order to weave a three-dimensional four-axis fabric as shown in FIGS. 7 and 8, as can be seen from FIG. 3
It will be installed in the direction.

The rod insertion device 15 inserts the latitudinal rods 2a between the warp rod groups 1 while lowering the warp rod groups 1 in accordance with the progress of weaving. By selectively driving the drive members 21a and 21b, the desired bushing rods 20a and 20b are protruded at a plurality of positions corresponding to the insertion portions of the bushing rods 20a and 20b. are sequentially inserted between longitudinal rod groups 1. FIG. 3 shows a state in which the bushing rod 2Db is projected by driving the driving member 21b, and the latitudinal rod in the plane P is inserted at its tip.

In order to sequentially beat the three-dimensional multiaxial fabric during weaving, a beater member 31 is mounted on the machine frame 10 above the weaving position, as shown in FIG. As shown in detail in FIGS. 4 to 6, this reed beating member 31 is generally a ring that surrounds the longitudinal rod group 1 and faces a portion of the latitudinal rod 2a that protrudes outward from the longitudinal rod group 1. The rod pressurizing surface 32 facing the latitudinal rods is formed in a shape such that it simultaneously hits the latitudinal rods 2a when the insertion of the latitudinal rods 2a ends after one cycle of insertion of the latitudinal rods. The perforated plate 13 is mounted on this reed beating member 31.

When beating the woven three-dimensional fabric 3 using the beating member 31, the bushing rod 20a or 20b is used to beat the weft rods 2a against the group 1 of the longitudinal rods set in an array by the holding means 11. each time the holding means 11 is inserted into the feed screw 12.
The longitudinal rod group 1 is moved in the axial direction, and the portion of the inserted latitudinal rod 2a that protrudes outward from the longitudinal rod group 1 is pressed against the beating member 31.

In the above-mentioned rod-type three-dimensional multiaxial fabric 3, the latitudinal rods 2a are inserted from a plurality of directions between the longitudinal rod groups l.
are in a state where they are combined with each other, so that even if a part of the weft direction rod 2a is pressed, the weaving state does not easily collapse. It is possible to perform sufficient reed beating without having to compact the entire area.

Note that during the above-mentioned beating, it is also possible to hold the longitudinal rod group 1 fixed on the machine frame 10 and press the beating member 31 against the woven three-dimensional fabric.

Moreover, since the beating member 31 is disposed above the weaving position, it can also be used as a guide for the inserted weft direction rod 2a.

[Effects of the Invention] According to the present invention detailed above, in a rod-type three-dimensional multiaxial fabric with four or more axes, by extremely simple means,
It is possible to carry out effective reed beating.
