DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod type three-dimensional multi-axis loom in which a reinforcing fiber bundle is formed into a rod by means of a matrix, and weaving is performed using the rod. It concerns the device.

[0002]

2. Description of the Related Art In a rod type three-dimensional multi-axis loom,
A large number of long warp rods are arranged and attached in parallel to a loom in advance, and weft rod groups are inserted into the warp rod groups from various directions at various inclination angles to perform multiaxial weaving. In this weaving, when inserting a weft rod group from a certain direction to a warp rod group in a parallel state, in a state where the rods constituting the weft rod group are arranged in parallel on one plane The insertion into the warp rod group is advantageous for simplifying the construction of the loom, controlling the weaving operation, and the like, and further facilitating beating.

In many cases, the weft rod group is inserted into the warp rod group at a constant inclination angle from a plurality of directions around the warp rod group. It is advantageous to hold the position and rotate the warp rod group around its central axis in accordance with its weft rod insertion direction, and furthermore, to position a large number of parallel arrangement weft rods on one horizontal plane. It is advantageous to make the warp rod group into which it is inserted rotatable in a state where it is tilted by a required angle in order to further simplify the construction of the loom, the control of the weaving operation, and the like. Of course, it may be possible to simplify the weaving control by inclining the plane in which a number of weft rods are arranged in parallel in relation to the insertion direction with respect to the warp rod, but in any case, the warp rod may be simplified. Advantageously, the group is tilted at an angle while being able to rotate about its central axis.

FIGS. 1 and 2 show an example of a rod type three-dimensional multi-axis loom to which the present invention is applied. It has a configuration capable of rotating around an axis. The configuration will be briefly described. A lower support 13 having a holding bottom 13a for holding a large number of the warp rods in a parallel state as a warp rod group is provided on an inclined guide 11 on a machine frame 10 of the multi-axis loom. The tilt guide 11 on the machine frame 10 is supported by the linear actuator 14 so as to be able to move up and down, and holds the upper part of the warp rod group.
Has an upper support 15 attached thereto. The lower support 13 and the upper support 15 are formed in a cylindrical shape with the central axes aligned, and are used for holding and holding a large number of warp rods in a state of being arranged in parallel and inclined.
As can be seen from FIG. 7, reed plates 16 and 17 are provided at the opposite ends, and are rotatable around their central axes by rotating motors 18 and 19.

In order to insert the weft rod group 2 arranged in parallel on one plane into the warp rod group 1 arranged in parallel between the reed plates 16 and 17, Two sets of weft rod insertion devices 2 for inserting weft rod groups 2
1 and 22 are provided. These weft rod insertion devices

6 and 17, are sequentially inserted into the warp rod group 1 from various directions.
The beating is performed by raising the lower support 13 having 3a.

However, in such a three-dimensional multi-axis loom, a large number of long warp rods in a parallel arrangement are formed by the warp rod group 1.
7, the warp rods are bent by their own weight as shown in FIG. 7, and as shown schematically in FIG. 8, the regular arrangement of the warp rods defined by the holes of the reed plates 16 and 17 ( A deviation occurs between the actual warp rod arrangement and the actual warp rod arrangement, making it difficult to insert the weft rod group, or moving the warp rod group 1 relative to the reed plate 17 with respect to the axis line for beating and pulling out the fabric. In the relative movement in the direction, there is a problem that the warp rod bites into the edge of the hole of the reed board 17 and the weaving operation becomes unstable. Further, when using the reed plates 16 and 17 having holes for aligning the warp rod group 1 properly, it is necessary to guide and insert the tip of the warp rod into each hole of the reed plate. Preparation requires relatively complicated work.
