Description

TECHNICAL FIELD The present invention relates to a method and an apparatus for inserting a weft direction rod between warp direction rods in a rod type three-dimensional multi-spindle loom.

[Prior Art] The inventors of the present invention previously described in Japanese Patent Application No. 63-249517,
We are making proposals related to a three-dimensional multiaxial woven fabric in which rods formed by connecting fiber bundles in a matrix are oriented in multiaxial directions.

In the case of such a rod-type three-dimensional woven fabric, in which each rod is a triaxial woven fabric that is orthogonal to each other, between the rods in a large number of parallel rod groups arranged in parallel, another orthogonal biaxial latitudinal rod is provided. The weaving can be performed by sequentially inserting the rods forming the group. When inserting this latitudinal rod group, a large number of rods constituting 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 are arranged, and they are inserted all at once between the rods of the longitudinal rod group. That is, rods for one cycle of the weave structure in the group of weft rods inserted from one direction can be arranged in a plane and inserted between the warp rods all at once.

However, the three-dimensional fabric having four or more axes has the following problems. That is, FIGS. 4 and 5 show the structure of a three-dimensional four-axis woven fabric, and in particular, FIG. 5 thereof shows the direction of the rod group 52 from the three directions tilted with respect to the longitudinal rod group 51 arranged in parallel.
The three-dimensional four-axis woven fabric 50 is shown as viewed from the inserting direction of one weft direction rod group 52. As can be seen from this figure, it is seen from one direction with respect to the warp direction rod group 51. Rods 52a, 52b, 52c, 52d, 52e or 52a, 52b, 52c ', 52 for one cycle of the weave structure of the weft direction rod group 52 to be inserted
d ′ and 52e ′ are in a plurality of parallel planes P ₁ and P ₂ slightly displaced in the weaving direction of the warp rod group 51, or one plane P ₃ in a complicated inclined state with respect to the warp rod group 51. It is inside. Therefore, the rods for one cycle of the weave direction rod group 52 which are inserted into the warp direction rod group 51 from one direction are used for the warp direction rod group 51 in the same manner as in the case of the three-dimensional triaxial woven fabric. When trying to insert all at once, the structure and manufacture of the weft direction rod insertion device in the loom become very complicated, for example, the height difference of each rod is added to the supporting surface of the weft direction rod group to be inserted.

[Problems to be Solved by the Invention] The technical problem of the present invention is to simplify the device for inserting the latitudinal rods in the above-mentioned three-dimensional polyaxial fabric, and in particular to arrange the latitudinal rods to be inserted. The purpose of the present invention is to simplify the device for inserting the latitudinal rod by making the supporting surface to be a flat surface installed in a simple orientation.

[Means for Solving the Problems] A rod insertion method of a rod-type three-dimensional multi-axis fabric according to the present invention for solving the above-mentioned problems is performed when inserting a weft direction rod in a rod-type three-dimensional multi-axis fabric having four or more axes. , 1 cycle of the weft direction rod group inserted from one direction is orthogonal to a plane parallel to both the warp direction rod and the weft direction rod, and parallel to the plane including the weft direction rod. Inserting devices that are arranged and arranged, and sequentially move the arranged latitudinal rods in the axial direction of the longitudinal rod group so that the latitudinal rods can be divided and inserted at a plurality of positions corresponding to insertion portions of the latitudinal rods between the longitudinal rods. Thus, the necessary latitudinal rods are selectively inserted from the latitudinal rods for one cycle.

Further, in the method of the present invention, each time the latitudinal rod is selectively inserted by the inserter capable of split insertion, the lapping rod is moved laterally to a position for the next selective insertion. Can also be inserted.

Further, the rod-type three-dimensional multi-axis fabric rod insertion device of the present invention is a device for inserting a weft-direction rod into a four-axis or more rod-type three-dimensional multi-axis fabric fabric. A rod supporting surface on which one cycle of the weave structure of the rod group is arranged is orthogonal to a plane parallel to both the warp direction rod and the weft direction rod, and is set in a plane including the weft direction rod. The insertion device that makes the supporting surface of the latitudinal rod relatively movable in the axial direction of the longitudinal rod group and presses the latitudinal rods arranged on the supporting surface to insert between the longitudinal rods is It is characterized in that it is divided according to the deviation of the weaving direction in one cycle.

[Operation] When inserting a weft direction rod in a four-axis or more rod type three-dimensional multi-axis fabric, one cycle of the weft direction rod group to be inserted from one direction is arranged on a plane with a simple orientation. Although many tissues cannot be inserted all at once, insertion of a latitudinal rod is made possible by selectively inserting the latitudinal rod required at multiple positions corresponding to the insertion part of the latitudinal rod by means of an insertion device that can be split and inserted. The device for is significantly simplified.
