1 to 4 show an example of the construction of a rod type three-dimensional multi-spindle loom equipped with a warp rod shedding device according to the present invention. In this three-dimensional multi-spindle loom, the warp rods 1a and the weft rods 2a used in the manufacture of the woven fabric are combined into a rod by previously binding a fiber bundle with a matrix, and the weaving described below is performed in the state of the rod thus formed. It is a thing.

The above-mentioned three-dimensional multi-spindle loom holds a warp rod group 1 in which a large number of warp rods 1a are arranged in parallel on a machine frame (not shown) with a required weft rod insertion gap therebetween. A holding member 11 for holding the rear rod group 1 at the lower end is provided. The holding member 11 supports the warp rod group 1 so that the warp rod group 1 can be moved up and down in its orientation direction by an elevating mechanism for elevating and lowering the fabric provided on the machine frame. As will be described later, the elevating mechanism also constitutes repulsion driving means for raising the three-dimensional fabric being woven and pressing the woven portion against the reed to beat the reed.

Further, in the three-dimensional multi-spindle loom, the warp rod group 1 which is arranged and held in parallel through the weft rod insertion gap,
A weft rod inserting device that inserts the weft rod group 2 from two directions orthogonal to the axial direction is provided, and the weaving is performed on three orthogonal axes. This weft rod inserting device is accommodated in a rod magazine 12 and is supplied in a state of being arranged in parallel on one rod arrangement plane 2
Is extruded from the extruding hole 12a by a weft rod extruding rod (not shown) and inserted between the warp rod groups 1 to weave the woven fabric into a three-dimensional multi-axis. The pushing out of the weft rod group 2 accommodated in the rod magazine 12 by the pushing rod is performed by inserting the pushing rod through the insertion hole 12b provided on the back side of the rod magazine 12 and pushing the rod out of the rod magazine. Is.

In the above-mentioned three-dimensional multi-spindle loom, a holding hole 16 for guiding and holding each of the warp rods 1a is provided above the weaving position where the weft rod group 2 is inserted into the warp rod group 1, and A support plate 15 that can be tilted by a shaft 17 is arranged in the central portion. This support plate 15
Is inserted through the large number of holding holes 16 and then, as shown in FIG.
As shown in FIG. 5, when the support plate 15 is held in a state of being obliquely crossed with respect to the war rod group 1, the inserted war rods 1a have a regular pitch, that is, the weft rods are inserted at intervals of the war rods 1a. The holding holes 16 are formed so that they are arranged at a pitch corresponding to the cross-sectional dimension of the weft rod 2a, where the amount of clearance added for ease is substantially eliminated. It should be noted that the holding hole 16 needs to have a margin such that the supporting rod 15 will not be damaged even if the supporting plate 15 tilts. As shown in FIGS. 1 and 2, the shaft 17 supporting the support plate 15 has a state (FIG. 3) in which the support plate 15 is obliquely crossed with respect to the warped rod group 1 and its angle. It is connected to a tilting device 18 which shifts to a state in which it is tilted in a direction orthogonal to (FIG. 4).

Further, as clearly shown in FIG. 1, between the support plate 15 having the warp rod holding hole 16 and the weaving position for inserting the weft rod group 2 into the warp rod group 1, Weft rod 2 inserted around the circumference of rod group 1
A reed 20 is provided that engages with the ends of the a-rod group 1 of a and protrudes to both sides to beat the reed. This reed 20 is fixed to the machine frame, and when the reed is beaten, the holding member 11 is raised by the above-described lifting mechanism, so that the three-dimensional fabric being woven is reed 20.
However, the machine frame may be provided with a repulsion driving means for pressing the reed 20 against the three-dimensional fabric being woven. 1 and 2, reference numeral 21 indicates a part of a machine frame that supports the shaft 17 of the support plate 15.

When weaving is performed using the three-dimensional multi-spindle loom having the above structure, first, the holding member 11 is made to hold a large number of warp rods 1a in parallel through the insertion gap of the weft rod 2a, and further, By inserting the respective warp rods 1a into the holding holes 16 of the support plate 15, the desired arrangement state is maintained. This arrangement is such that when the support plate 15 is held in a slanting state as shown in FIG. 3 with respect to the warp rod group, each inserted warp rod 1a has a regular pitch as shown in FIG. It is arranged at a pitch corresponding to the cross-sectional dimension of 2a.

In order to open the space between the war rods 1a in order to insert the weft rod group 2 into the war rod group 1, the support plate 15 is moved from the oblique state of FIG. As shown in FIG. 4, the rods are dislocated to a state orthogonal to or close to the warped rod group 1. As a result, the distance between the warp rods 1a is evenly widened for inserting the weft rod group 2 by a distance obtained according to the tilt angle of the support plate 15. In this case, the warped rods 1a are opened in the plane orthogonal to the rotation axis of the support plate 15 in one direction (the direction of the straight line L in FIG. 2) with an interval widened, so that the weft rod group 2 is inserted. When the direction is the same as or close to the opening direction of the warped rod, a sufficient opening cannot be obtained between the warped rods when viewed from that direction, but an arrow separated from the direction of the straight line L as much as possible. By setting the weft rod group 2 to be inserted in the A direction or the like, it is possible to obtain a sufficient opening and easily insert the weft rod group.

The insertion of the weft rod group 2 into the warp rod group 1 can be easily performed by using a known means. Further, the beating of the inserted wed rod is performed by inserting the appropriate amount of the wed rod group 2 into the war rod group 1 and then inserting the reed 20 provided so as to surround the perimeter of the war rod group 1 into the war rod 2a. The three-dimensional fabric is pressed against the reed 20 while the three-dimensional fabric is pressed against the reeds 20. The lifting mechanism of the holding member 11 lowers the three-dimensional fabric as the weaving progresses. Can be used as a beating driving means, and the holding member 11 can be raised.

FIGS. 5 and 6 show an example of the structure of a three-dimensional multi-spindle loom which is equipped with the warp rod shedding device according to the present invention and which is suitable for weaving multi-spindle triaxial or four or more axes. Shows. This three-dimensional multi-spindle loom, like the three-dimensional multi-spindle loom described with reference to FIGS. 1 to 4, has a holding member 31 for holding the warp rod group 1 at the lower end on a machine frame (not shown). However, this holding member 31 can be raised and lowered in an inclined direction along the machine frame by an elevating mechanism for raising and lowering the fabric provided on the machine frame. In addition, in the plurality of weft rod inserting devices 30, the rod arrangement planes of the weft rod group 2 to be inserted into the warped rod group 1 are parallel to each other, and are oblique to the axial direction of the warped rod group 1. However, since the rod arrangement planes of the double weft rod inserting device 30 are arranged horizontally, the warp rod group 1 held by the holding member 31 is formed at an angle corresponding to the insertion angle of the weft rod group. It is inclined.

The weft rod inserting device 30 supplies the weft rod group 2 supplied to the rod magazine 32 having the same structure as that of the rod magazine 12 of FIG. 1 in a state of being arranged in parallel on one rod arrangement plane. The weft rod pushing rod 30b housed and driven by the actuator 30a is inserted through the insertion hole (insertion hole 12b of FIG. 1) of the rod magazine 32, and the weft rod group 2 is pushed through the push hole (extrusion hole 12a of FIG. 1).
Is pushed out and inserted between the rod groups 1.

In the three-dimensional multi-spindle loom, a holding cylinder 33 for holding the warp rod group 1 extending upward is provided above the weaving position where the weft rod group 2 is inserted into the warp rod group 1. A support plate 35 having a holding hole (holding hole 16 in FIG. 1) for inserting each of the warp rods 1a is attached to the lower end thereof, like the supporting plate 15 in the loom of FIG. The support plate 35 is tilted together with the holding cylinder 33, and the oblique state with respect to the warped rod group 1 as indicated by the solid line and the angle thereof are determined as follows.
The shaft 37 attached to the holding cylinder 33 is tilted by a tilting device 38 in order to shift the shaft 37 to a state of a chain line tilted in a direction orthogonal to the direction.
Connected to. The inclination angle of the support plate 35 in the oblique state shown by the solid line is parallel to the rod arrangement plane in the plurality of weft rod insertion devices 30 because the support plate 35 also serves as a reed. The structure and operation of the support plate 35 are substantially the same as those described with reference to FIGS. 1 to 4 except for the points described here.

When weaving with the three-dimensional multi-spindle loom having the above-mentioned structure, as in the case described with reference to FIGS. 1 to 4, a large number of warp rods 1a are arranged and held in parallel in the holding member 31, and further Each supporting rod 35 is inserted into the holding hole of the supporting plate 35 to hold the supporting rod 35 in a desired arrangement state, and the supporting rod 35 is opened for inserting the weft rod group 2a. Is driven to shift the solid line position in FIG. 6 to the chain line position in FIG.
As a result, the distance between the warp rods 1a is uniformly widened for inserting the weft rod group 2 by a distance obtained according to the tilt angle of the support plate 35, and the weft rods are inserted from the plural directions by the weft rod inserting device 30. Group 2 insertion is possible.

In the repulsion of the inserted weft rod group 2, the inclination angle of the support plate 35 when the support plate 35 is obliquely made parallel to the rod arrangement plane in the weft rod insertion device 30. The plate 35 can also be used as a reed. Therefore, after inserting an appropriate amount of weft rod groups into the warp rods, the elevating mechanism of the holding member 31 that lowers the three-dimensional fabrics in accordance with the progress of weaving is used as a beating driving means to drive the three-dimensional fabrics being woven into the warp rod axis line. By moving in the direction, the support plate 35 can be beaten.

In this three-dimensional multi-spindle loom, the weft rod group 2 is arranged in a different oblique direction with respect to the warp rod group 1.
In the case of inserting the support plate 35, the support plate 35 is removed from the holding cylinder 33, and then the holding member 31 is attached to the rear rod group 1 and the support plate 35 inserted therethrough.
By rotating the support plate 35 to the holding cylinder 33 in that state by rotating the weft rod group about the central axis of the above, the weft rod group can be inserted in exactly the same manner as described above.

[0027]

As described above in detail, according to the present invention, the distance between the war rods is reduced while using the support plate for the war rods in which the clearance amount added to the distance between the war rods is substantially eliminated. The weft rod can be easily expanded for insertion, and the fiber content of the woven fabric can be significantly increased thereby, and the spacing between the warp rods can be increased by extremely simple means. It is possible to provide a trans-rod opening means which can be simultaneously and uniformly expanded for insertion of the rods and whose opening amount can be arbitrarily set by the inclination amount of the support plate.
