DETAILED DESCRIPTION OF THE INVENTION

[0011] Preferred embodiments of the present invention will now be described in detail with reference to the drawings.

[0012] The terms "first," "second," etc. in this disclosure are used for identification purposes only and are not intended to impose any order on their objects.

[0013] 1 to 7 show an example of a braided structure manufacturing apparatus according to the present invention. The braided structure manufacturing apparatus A1 of this embodiment includes a stand 1, a shaft material feed mechanism 2, a main support 3, a plurality of individual supports 4, a plurality of carriers 5, a drive motor 6, and a transmission mechanism 7.

[0014] The braided structure manufacturing apparatus A1 is an apparatus for manufacturing a braided structure 9 by winding a plurality of first wires 91 and a plurality of second wires 92 around a shaft material 90. The shaft material 90 is a member having a shape extending in the axial direction N, and the material and specific configuration thereof are not limited in any way. The shaft material 90 may be a solid rod material (strip material) or a hollow tubular material. The material and specific configuration of the first wires 91 and the second wires 92 are not limited in any way. The first wires 91 and the second wires 92 are provided for various purposes, such as improving the rigidity of the shaft material 90, protecting the shaft material 90, or decorating the appearance of the shaft material 90. The material, wire diameter, etc. of the first wires 91 and the second wires 92 are not limited in any way and may be made of, for example, metal, resin, various fibers, etc.

[0015] The frame 1 is a base of the braided structure manufacturing apparatus A1. The frame 1 is made of, for example, steel material or resin. In the illustrated example, the frame 1 has a stand 11. The stand 11 supports the main support 3.

[0016] The shaft material feed-out mechanism 2 is a mechanism that feeds out the braided structure 9 in the axial direction N. The specific configuration of the shaft material feed-out mechanism 2 is not limited in any way, and in the example shown, it has, for example, a motor 21 and a plurality of rollers 22. The motor 21 is a drive source that drives at least one of the plurality of rollers 22. The plurality of rollers 22 feed out the shaft material 90 (braided structure 9) by rotating while sandwiching the shaft material 90 (braided structure 9).

[0017] The main support 3 supports a plurality of individual support members 4. The specific configuration of the main support member 3 is not limited in any way, and in the illustrated example, it has a disk portion 31, a cylindrical portion 32, and a pulley 33.

[0018] The braided structure manufacturing apparatus A1 may include, for example, a brake mechanism (not shown) to maintain the main support 3 fixed to the frame 1. The braided structure manufacturing apparatus A1 may also include a sensor (not shown) for detecting the rotational position of the disk portion 31.

[0019] The disc portion 31 is a circular member when viewed from the front. In this example, the disc portion 31 is composed of a first plate portion 311 and a second plate portion 312. The first plate portion 311 and the second plate portion 312 are each a circular plate-like member, and are arranged parallel to and spaced apart from each other in the axial direction N. An insertion portion 313 is formed in the disc portion 31. The insertion portion 313 is a through hole for inserting the shaft member 90 therethrough.

[0020] The cylindrical portion 32 is a cylindrical member extending in the axial direction N. In this example, the cylindrical portion 32 is inserted into the insertion portion 313 of the disk portion 31. The cylindrical portion 32 and the disk portion 31 are fixed to each other. The cylindrical portion 32 is rotatably supported by the stand 11.

[0021] The pulley 33 is attached near the rear end of the axial direction N of the cylindrical portion 32. The pulley 33 is a portion to which the driving force is transmitted from the transmission mechanism 7. When the driving force is transmitted to the pulley 33, the main support body 3 rotates in the rotation direction R0 in the circumferential direction around the insertion portion 313 (shaft material 90) as shown in FIG.

[0022] As shown in Fig. 4, the plurality of individual supports 4 are capable of primary rotation in a rotation direction R0 in the circumferential direction around the insertion portion 313 (shaft 90) and secondary rotation in which they rotate around their own rotation axes. The plurality of individual supports 4 include a plurality of first individual supports 4A and a plurality of second individual supports 4B. There is no limitation on the number of these, and in the illustrated example, eight individual supports 4 include four first individual supports 4A and four second individual supports 4B. The four first individual supports 4A and four second individual supports 4B are alternately arranged in the circumferential direction around the insertion portion 313 (shaft 90).

[0023] The specific configuration of the individual support member 4 is not limited in any way, and in this example, the individual support member 4 has an engagement fin 41, a shaft 42, and a gear 43. The engagement fin 41 has a generally circular shape when viewed from the front, and in the example shown, one individual support member 4 has two engagement fins 41. The engagement fins 41 perform the function of engaging with the carrier 5. In the example shown, the engagement fin 41 has a plurality of recesses 411. The recesses 411 are portions recessed from the periphery of the engagement fin 41 toward the center. In the example shown, the engagement fin 41 has four recesses 411.

[0024] The shaft 42 is fixed to the center of the engagement fin 41, and is supported by the disk portion 31 of the main support 3 so as to be able to rotate in a secondary direction. The gear 43 is attached near the rear end of the shaft 42 in the axial direction N. A driving force from the drive motor 6 is input to the gear 43 of any of the individual support bodies 4. As shown in FIG. 5, the gears 43 of adjacent individual support bodies 4 mesh with each other. As a result, the four first individual support bodies 4A perform a secondary rotational movement in a first rotational direction Ra, and the four second individual support bodies 4B perform a secondary rotational movement in a second rotational direction Rb opposite to the first rotational direction Ra. The secondary rotational movements of the multiple individual support bodies 4 are linked to each other.

[0025] The plurality of carriers 5 are detachably supported by the plurality of individual supports 4 while feeding out the first wire rod 91 or the second wire rod 92. The specific configuration of the carrier 5 is not limited in any way, and in the illustrated example, the carrier 5 has a bobbin 51, a rod 52, an engagement shaft 53, and an engagement fin 54 as shown in FIG.

[0026] The bobbin 51 has the first wire 91 or the second wire 92 wound thereon and feeds them out. The rod 52 is a rod-shaped member for appropriately guiding the fed first wire 91 or the second wire 92. The engagement shaft 53 extends in the axial direction N and is a portion that fits into and disengages from the recesses 411 of the engagement fins 41 of the individual support bodies 4. The engagement fins 54 are fixed to the engagement shaft 53 and are circular overall. In the illustrated example, one carrier 5 has two engagement fins 54. One of the two engagement fins 54 is located between two engagement fins 41 of the individual support bodies 4. As a result, the carrier 5 is held by multiple individual support bodies 4.

[0027] Various mechanisms may be employed to define the movement path of the carrier 5 in the second mode, which will be described later. For example, a slit 3111 may be formed in the first plate 311, and a guide 314 may be appropriately provided between the first plate 311 and the second plate 312. The slit 3111 is an opening that allows the rear end of the engagement shaft 53 or a predetermined protrusion provided at the rear end of the engagement shaft 53 to enter between the first plate 311 and the second plate 312. The guide 314 defines the movement path of the carrier 5 by appropriately contacting or engaging with the rear end of the engagement shaft 53 or a predetermined protrusion provided at the rear end of the engagement shaft 53. The structure or mechanism for defining the movement path of the carrier 5 is not particularly limited.

[0028] In FIG. 4, for ease of understanding, only the engagement shaft 53 of the carrier 5 is shown. The number of the multiple carriers 5 is not limited in any way, and in the example shown, 16 carriers 5 are provided. The 16 carriers 5 include eight first carriers 5A and eight second carriers 5B. The first carriers 5A and the second carriers 5B have the same configuration as described above. The first carrier 5A feeds the first wire rod 91, and the second carrier 5B feeds the second wire rod 92. The first carrier 5A and the second carrier 5B have different movement paths in the second mode, which will be described later.

[0029] The drive motor 6 is a drive source for rotating the main support 3 and the plurality of individual support bodies 4. The drive motor 6 is a general electric motor, and for example, a servo motor may be used. In this example, a case will be described in which the main support body 3 and the plurality of individual support bodies 4 are driven by one drive motor 6, but this is not limiting, and for example, two dedicated drive motors 6 may be used.

[0030] As shown in FIG. 2 , a first gear 61 and a second gear 62 are provided on both sides of the drive motor 6 in the axial direction N. The first gear 61 transmits driving force to a gear 43 of one of the multiple individual support bodies 4. The second gear 62 transmits driving force to a transmission mechanism 7. In this example, the drive motor 6 is supported by a lifting mechanism 63. The lifting mechanism 63 has, for example, an air cylinder or the like, and raises and lowers the drive motor 6 in the vertical direction. When the drive motor 6 is raised by the lifting mechanism 63, the first gear 61 meshes with the gear 43 of one of the individual support bodies 4. On the other hand, when the drive motor 6 is lowered by the lifting mechanism 63, the second gear 62 meshes with a gear 71 of the transmission mechanism 7.

[0031] The transmission mechanism 7 is a mechanism that transmits the driving force of the drive motor 6 to the main support 3. The specific configuration of the transmission mechanism 7 is not limited in any way. Furthermore, if a dedicated drive motor 6 is provided for driving the main support 3, the transmission mechanism 7 does not need to be provided. In the illustrated example, the transmission mechanism 7 has a shaft 70, a gear 71, a pulley 72, and a belt 73. The shaft 70 is oriented along the axial direction N and is rotatably supported. The gear 71 is attached to one end of the shaft 70 and engages with the second gear 62. The pulley 72 is attached to the other end of the shaft 70. The belt 73 is wound around the pulley 72 and the pulley 33 of the main support 3. When the second gear 62 engages with the gear 71, the driving force is transmitted to the pulley 33 via the shaft 70, the pulley 72, and the belt 73, and the main support 3 rotates in the rotational direction R0 shown in FIG. 4 .

[0032] Next, the operation of the braided structure manufacturing apparatus A1 will be described.

[0033] The braided structure manufacturing apparatus A1 has a first mode and a second mode. In the first mode, the driving motor 6 is lowered by the lifting mechanism 63. This transmits the driving force of the driving motor 6 to the main support 3 via the transmission mechanism 7, causing the main support 3 to rotate in the rotation direction R0. Meanwhile, the multiple individual supports 4 are fixed relative to the main support 3, preventing their individual secondary rotations. As a result, all of the multiple carriers 5 are fixed relative to the main support 3 and all rotate primarily in the rotation direction R0. In this state, a first wire rod 91 from the first carrier 5A and a second wire rod 92 from the second carrier 5B are wound in the same direction around a shaft 90 fed by the shaft feed mechanism 2. The first section ScA of the braided structure 9 shown in FIG. 8 is a section manufactured in the first mode.

[0034] In the second mode, the drive motor 6 is raised by the lifting mechanism 63. As a result, the driving force of the drive motor 6 is transmitted to the multiple individual supports 4, and as shown in Figures 6 and 7, the first individual support 4A performs a secondary rotation in the first rotation direction Ra, and the second individual support 4B performs a secondary rotation in the second rotation direction Rb. Meanwhile, the main support 3 is fixed and prevented from rotating. As a result, the primary rotation of the multiple individual supports 4 is prevented.

[0035] The plurality of carriers 5 sequentially transfer the plurality of individual supports 4 in accordance with the secondary rotation of the plurality of individual supports 4. As the engagement shafts 53 of the first carrier 5A shown in FIG. 4 are sequentially transferred to the recessed portions 411 of the adjacent individual supports 4, the first carrier 5A moves along a first path TrA shown in FIG. 6. As a result, the first carrier 5A moves around the shaft material 90 in a first rotation direction Ra. Meanwhile, as the engagement shafts 53 of the second carrier 5B shown in FIG. 4 are sequentially transferred to the recessed portions 411 of the adjacent individual supports 4, the second carrier 5B moves along a second path TrB shown in FIG. 7. As a result, the second carrier 5B moves around the shaft material 90 in a second rotation direction Rb. In this state, the first wire rod 91 from the first carrier 5A and the second wire rod 92 from the second carrier 5B are wound in opposite directions around the shaft material 90 fed out by the shaft material feeding mechanism 2. The second section ScB of the braided structure 9 shown in FIG. 8 is a section produced in the second mode.

[0036] The switching between the first mode and the second mode may be performed by temporarily stopping the feeding of the shaft material 90, or may be performed while continuing the feeding of the shaft material 90. Also, the switching to the second mode may be performed after the first mode, or the switching to the first mode may be performed after the second mode.

[0037] Next, the operation of the braided structure manufacturing apparatus A1 will be described.

[0038] According to this embodiment, the braided structure manufacturing apparatus A1 can perform the first mode and the second mode without performing so-called changeover work, such as replacing the plurality of carriers 5 or the plurality of individual supports 4, or changing the support state. Therefore, it is possible to appropriately manufacture the braided structure 9 having the first section ScA and the second section ScB in which the first wire rod 91 and the second wire rod 92 are wound in different ways.

[0039] Because each of the multiple individual supports 4 is supported by the main support 3 so as to be capable of secondary rotational movement, the first mode can be performed by rotating the main support 3 while preventing the secondary rotational movement of the multiple individual supports 4. On the other hand, the second mode can be performed by fixing the main support 3 to prevent rotation and allowing the multiple individual supports 4 to perform secondary rotational movement. Switching between the first mode and the second mode can be achieved simply by switching the rotational states of the main support 3 and the multiple individual supports 4, and does not require, for example, changing the setup of the multiple carriers 5. Therefore, it is possible to more efficiently manufacture the braided structure 9 having a first section ScA and a second section ScB in which the first wire 91 and the second wire 92 are wound in different ways.

[0040] The braided structure manufacturing apparatus according to the present invention is not limited to the above-described embodiment, and the specific configuration of each part of the braided structure manufacturing apparatus according to the present invention can be freely designed and modified in various ways.

[0041] Unlike the braided structure manufacturing apparatus A1, the braided structure manufacturing apparatus A1 may not have a main support body 3. For example, the braided structure manufacturing apparatus A1 may have a configuration in which a plurality of individual supports 4 are supported by a member fixed to the frame 1 so as to be capable of main and secondary rotational movement. Furthermore, the mechanism that enables the main and secondary rotational movement of the plurality of individual supports 4 may be any of a variety of mechanisms, such as a mechanism using a plurality of motors, a mechanism using magnetic force, or a mechanism combining mechanical elements such as gears and cam grooves.
