Description

Description: TECHNICAL FIELD The present invention relates to a method and an apparatus for laminating a three-dimensional fabric used as a base material of a composite material or the like.

[Conventional technology]

Japanese Patent Application Laid-Open No. Sho 59-7
No. 1475, JP-B-62-14667, JP-A-63-42955 and the like are known.

In the above-mentioned Japanese Patent Application Laid-Open No. 59-71475, an upright bar member is fixed on the upper and lower sides by annular plates, yarns are arranged along the bar members, and finally, each bar member is replaced with a yarn.

In addition, Japanese Patent Publication No. 62-14667 discloses that the yarns are alternately turned in one direction and in a direction intersecting with the arrangement of upright lattice bars in a meandering arrangement and stacked in a desired thickness.
Finally, yarns along the above-mentioned laminating direction are replaced with the respective lattice bars at the positions of the respective lattice bars.

Furthermore, Japanese Patent Application Laid-Open No. 63-42955 discloses a method for producing a three-dimensional woven fabric using a thread guide tube having the same arrangement as the lattice bar, in which case the deflection of the thread guide tube is reduced. It discloses that a spacer that prevents disorder in alignment and that also serves as a pressing member for the laminate is used.

[Problems to be solved by the invention]

In JP-A-59-71457, since the bar member is fixed up and down, the yarn spacing is fixed, so that the yarn density becomes uniform. However, since the bar member is fixed up and down by the annular body, the pitch of the bar member cannot be easily changed, and there is a problem that it is not easy to cope with three-dimensional fabrics of various sizes and shapes.

In addition, Japanese Patent Publication No. 62-14667 has a structure in which a lattice bar is cantilevered, so that bending occurs on the free end side. In particular, in order to increase the yarn density of the three-dimensional fabric, a thin lattice bar is used. Therefore, when the yarn is arranged in a meandering manner, the lattice bar is bent, the alignment of the lattice bar is disturbed, and the three-dimensional fabric is The yarn density becomes uneven.

Furthermore, Japanese Patent Application Laid-Open No. 63-42955 can prevent the lattice bar from being bent by using a spacer.
No suitable spacer is used for laminating the yarn into a cylindrical shape or a partial cylindrical shape, and measures are taken to prevent yarn breakage and fluffing of the yarn and to facilitate switching of yarn types. Not.

As described above, each of the conventionally known techniques has a problem, and has not been satisfactory.

The present invention has been proposed in view of the above-mentioned problems of the prior art, and its object is to be suitable for laminating yarns in a cylindrical or partial cylindrical shape, and to reduce the yarn density. It is an object of the present invention to provide a method and an apparatus for laminating a three-dimensional fabric, which is uniform and facilitates the prevention of thread breakage and fluffing and the switching of thread types.

[Means for solving the problem]

To achieve the above object, one of the methods of the present invention is to arrange a plurality of mutually parallel and perpendicular poles in a cylindrical or sub-cylindrical contour region in a radial arrangement along a plurality of concentric circles. By appropriately changing the yarn supply head in the circumferential direction and the radial direction intersecting the same along the arrangement of the poles and meandering the yarn supply head, the yarns fed from the yarn supply head are arranged in layers between the poles. In a method of laminating a three-dimensional woven fabric that repeats this to a desired thickness,
During the operation of stacking the yarn between the poles by the yarn supply head,
The poles are stacked while the spacing between the poles is fixed by separators inserted in the radial direction between the poles.

In the present invention, the yarn fed from the yarn supply head can be switched and supplied to a yarn of a different kind at an arbitrary time.

Further, in the present invention, the unwinding direction of the yarn unwound from the yarn supply head is inclined backward in the traveling direction of the yarn entanglement head.

One of the devices of the present invention is arranged radially outside the array of poles, has a comb-like tip, is capable of moving back and forth toward the center of the pole array, and has a comb at the entry end. A plurality of separators are used in which the toothed tip is rotatable between a horizontal state and a vertical state, and each pole can be immovably held in the horizontal state.

In addition, the present invention uses a press member that has the same arrangement as the separator, is capable of moving back and forth toward the center of the pole array, and is installed so as to be movable in the longitudinal direction of the pole, and presses the laminate along the pole. Things.

In addition, the present invention has a support base movable along the arrangement of the poles by a two-dimensional driving means together with the separator and the press member, and is pivotably supported on the support base. A plurality of heads having a yarn guide pipe are installed on the swivel table, and each of the heads supports the yarn guide pipe that feeds out and supplies a yarn so as to be tiltable in the traveling direction of the head, and supports the head.
