In accordance with the example shown in FIG. 3 and FIG. 4, the rotation drive mechanism 7 is comprised of a rotation drive source 11 connected to the second bobbin carrier driving disk 6B via a rotation shaft 10B.

For instance, when the first bobbin carrier driving disk 6B is rotated anti-clockwise with the rotation drive source 11, it is possible to rotate the first bobbin carrier driving disk 6A and the third bobbin carrier driving disk 6C clockwise respectively.

[0050] A bobbin carrier transfer mechanism 8A of the first embodiment shown in FIG. 3 and FIG. 4 is constructed on the upper end of the rotation shaft 10 in the respective bobbin carrier driving disks 6. The bobbin carrier transfer mechanism 8A of the first embodiment, for instance, comprising six pieces of a movable pressure piece 16 which is gained momentum in the closed direction all the time by a spring 15, a pressure support member 17 to pressurize the movable pressure piece 16 in the open direction, as opposed to the spring 15, to support, and a rotation shaft vertical motion means 18 to move the rotation shaft 10 up or down, maintains the movable pressure piece 16 in the closed condition, while the rotation shaft 10 is ascending by the rotation shaft vertical motion means 18, and maintains the movable pressure piece 16 in the open condition, while the rotation shaft 10 is descending.

[0051] In accordance with FIG. 3 and FIG. 4, the movable pressure piece 16 in the first bobbin carrier driving disk 6A on the diverged is in the closed condition, and the movable pressure piece 16 in the second bobbin carrier driving disk 6B in the center is in the open condition, and the bobbin carrier 2 is stowed to be supported in the condition of being pushed into the bobbin carrier shaft receiving entrance 9 in the first bobbin carrier driving disks 6A with an action end 16a of the movable pressure piece 16 in the second bobbin carrier driving disk 6B.

In accordance with FIG. 3, when the rotation shaft 10 of the first bobbin carrier driving disk 6A side is ascending, the movable pressure piece 16 is kept closed. In this condition, if the rotation shaft 10 of the first bobbin carrier driving disk 6B side descends, it opens the movable pressure piece 16 of the second bobbin carrier driving disk 6B side and the bobbin carrier 2 is accepted in the bobbin shaft receiving entrance 9 of the first bobbin carrier driving disk 6A side to be supported.

[0054] As is apparent from FIG. 4, in accordance with the bobbin carrier transfer mechanism 8 of the first embodiment, when the movable pressure piece 16 of the first bobbin carrier driving disk GA side is in the closed condition, the surrounding movable pressure pieces 16 of the second bobbin carrier driving disks 6B side and the third bobbin carrier driving disks 6C side are all in the open condition, and three pieces of bobbin carriers 2 are accepted in the bobbin shaft receiving entrance 9 of the first bobbin carrier driving disk 6A side to be supported.

As described above, by following the process of FIG. 6, FIG. 7 and FIG. 8, a 3X structure ST1 is composed.

For instance, when the first bobbin carrier driving disk 6B is rotated anti-clockwise with the rotation drive source 11, it is possible to rotate the first bobbin carrier driving disk 6A and the third bobbin carrier driving disk 6C clockwise respectively.

[0064] The bobbin carrier transfer mechanism 8B of the second embodiment shown in FIG. 5A is constructed on the upper end of the rotation shaft 10 in the respective bobbin carrier driving disks 6. This bobbin carrier transfer mechanism 8B of the second embodiment, for instance, provided with a cam member 23 which has a large-diameter cam face 23a and a small-diameter cam face 23b, both having a shape of an inverted truncated cone, a cam follower 24 installed on the bottom end side of the bobbin carrier 2 described later, and a rotation shaft vertical motion means 25 to move the rotation shaft 10 up or down, is composed so that the cam follower 24, installed on the bottom end side of the bobbin carrier 2, touches the small-diameter cam face 23b of the cam member 23, while the rotation shaft 10 is ascending by the rotation shaft vertical motion means 25, and the cam follower 24, installed on the bottom end side of the bobbin carrier 2, touches the large-diameter cam face 23a of the cam member 23, while the rotation shaft 10 is descending.

The bobbin carrier driving disk is rotated several times to individually twist and entangle the linear structures A1, C2, L3, D4, the linear structures A2, D3, B4, F1, the linear structures A3, F4, G1, E2, and the linear structures A4, E1, M2, C3, which are from respective bobbin carrier 2, in the 4X confounding form, forming the 4X confounding section Tw2 of the second layer respectively, and adjacent linear structures are confounded each other in the 4X form, linking to compose a three dimensional structure in succession.

[0070] Referring now to FIG. 11, FIG. 12 and FIG. 13, the following is the explanation regarding the composition process of a 6X-3X three dimensional structure ST3 shown in FIG. 2C. FIG. 11 through FIG. 13 illustrates the detailed manufacturing process of a 6X-3X structure shown in FIG. 2C, and FIG. 11 is a schematic plan view showing the condition that six bobbin carriers are respectively supported by each of the first bobbin carrier driving disk, and FIG. 12 illustrates the condition that, in the condition shown in FIG. 11, the bobbin carrier driving disk is rotated several times to twist and entangle linear structures from respective bobbin carriers in a 6X confounding form, forming the 6X confounding section Tw1 of the first layer, then the bobbin carrier is transferred three at a time from each of the first bobbin carrier driving disk 6A to each of the second bobbin carrier driving disk 6B to be supported, and FIG. 13 shows the condition that six pieces of bobbin carriers are transferred to be supported. As mentioned above, a three dimensional 6X-3X structure ST3 is composed by going through the steps of FIG. 11, FIG. 12 and FIG. 13.

[0071] In the stage shown in FIG. 11, six pieces of bobbin carriers 2 are respectively supported to each of the first bobbin carrier driving disk 6A, and linear structures A1, A2, A3, A4, A5, A6 are controlled by one of the first bobbin carrier driving disk 6A, and the bobbin carrier driving disk is rotated several times to twist and entangle the linear structures A1, A2, A3, A4, A5, A6 from each bobbin carrier 2 in the 6X confounding shape, forming a 6X confounding section Tw1 of the first layer. And then, the bobbin carrier 2, controlled by the first bobbin carrier driving disk 6A, is transferred to six pieces of the second adjacent bobbin carrier driving disks 6B, and the first of which controls linear structures A1, G3, B5, and the second of which controls linear structures A2, B4, C6, and the third of which controls linear structures A3, C5, D1, and the fourth of which controls linear structures A4, D6, E2, and the fifth of which controls linear structures A5, E1, F3, and the sixth of which controls linear structures A6, F2, G4. The bobbin carrier driving disk is rotated several times to individually twist and entangle the linear structures A1, G3, B5, the linear structures A2, B4, C6, the linear structures A3, C5, D1, the linear structures A4, D6, E2, the linear structures A5, E1, F3, and the linear structures A6, F2, G4, which are from respective bobbin carriers 2, in the 3X confounding form to form the 3X confounding section Tw2 of the second layer respectively, and adjacent linear structures are confounded each other in the 6X form and 3X form alternately, linking to compose three dimensional structures in succession.

[0072] Referring now to FIG. 14 and FIG. 15, the following is the explanation regarding the beating means for beating convergent junction of said linear structure 2 in a manufacturing apparatus for a three dimensional structure of the present invention. FIG. 14 is a schematic perspective diagram showing the concrete composition example of beating means 4 for beating this confounding section after the linear structures are twisted and entangled to form a confounding section in the manufacturing apparatus for a three dimensional structure of the present invention, and FIG. 15 illustrates the concrete composition example of a reed structured solid in said beating means 4, and FIG. 15A is a schematic plan view showing a closed condition of reeds in a reed structured solid with a solid line and an open condition of reeds with an assumed line, and FIG. 15B is a schematic perspective view showing one form of reeds in the reed structured solid.

[0073] The beating means 4 is composed of three reed structured solids 26 which beat convergent junction of the linear structures from at least three directions. The reed structured solid 26 in the beating means 4, as shown in FIG. 15A and FIG. 15B, comprises a pair of pivots 28 and a plurality of reed pieces 29 provided at a base section 27. A plurality of reed pieces 29 mentioned above are connected via the pivots 28 by a connecting rod 30 so that they come closer or come away in parallel with each other in the direction of the length of reed pieces 29.

[0074] The beating means 4 comprises a reed structured solid drive mechanism 31, which is composed to drive the reed solid 26 forward or backward in arrows Y2 directions, and a reed piece open/close mechanism 32 to open or close the reed pieces 29 in the reed structured solid 26. The reed structured solid drive mechanism 31 is provided with a reed support device 34, which is in a rectilinear reciprocating motion by a drive source 33, and it is possible to reciprocate in arrows Y1 directions in FIG. 1. The reed piece open/close mechanism 32, constructed on the reed support device 34, has a block member 36 which moves back and forth rectilinearly by a drive source 35 and the reed structured solid 26, constructed towards the block member 36 via link mechanism 37, and open or close the reed pieces 29 in the reed structured solid 26 as the reed structured solid 26 is moved back and forth by the drive source 35.

[0075] In a manufacturing apparatus for a three dimensional structure of the present invention, when a linear structure 1 applied as a material of the three dimensional structure is metal fiber, which possesses a relatively high stiffness such as a wire, it is impossible to carry out enough beating only with the beating means 4 and enough certain torsion to give at the X confounding structural section. Thus, with reference to the beating means 4, the present invention comprises at least one of the combination of a torsion reinforcing means 41, a forced torsion means 51, and forced transferring means 61, 71, 81.

[0076] In a manufacturing apparatus for a three dimensional structure of the present invention, FIG. 16 is a concrete example of the torsion reinforcing means 41 to reinforce a turning force to the linear structure 1, when the linear structure 1 applied as a material of the three dimensional structure is metal fiber, which possesses a high stiffness such as a wire, and FIG. 16A is a schematic plan view thereof, and FIG. 16B is a schematic elevation thereof. The torsion reinforcing means 41 of this embodiment is comprised of combinations as follows, a driven spur gear 44 with the first plate 42A, a driving spur gear 43 with the second plate 42B, the driven spur gear 45 with the third plate 42C, and the driven spur gears 44, 45 engaged in the driving spur gear 43. The respective plates 42A, 42B, 42C and the respective spur gears 43, 44, 45 are provided with six flutes 46 respectively to accept the linear structure 1.

[0077] On the other hand, FIG. 17 illustrates the torsion reinforcing means of another composition example shown in FIG. 16 and is a schematic elevation showing an example which torsion reinforcing means is composed of helical gears 47, 48, 49 instead of the spur gears 43, 44, 45. In the case of this embodiment, the respective plates 42A, 42B, 42C and the respective spur gears 47, 48, 49 are provided with six flutes 46 respectively to accept the linear structure 1.

[0078]
FIG. 18 is a schematic elevation showing a basic composition example of the forced torsion means 51 combined to twist the linear structure forcibly nearby the torsion confounding section, and FIG. 19 illustrates the details of a torsion section in said forced torsion means 51, and FIG. 19A is a schematic elevation thereof, and FIG. 19B is a schematic end view showing the side of end section.

[0079] In this embodiment, the forced torsion means 51 is composed of rotation shafts 52A, 52B, 52C, which have respective universal joints 53A, 53B, 53C reaching from respective rotation shafts 10A, 10B, 10C in the bobbin carrier driving disks 6A, 6B, 6C, and linear structure torsion set members 54A, 54B, 54C at the tip sections. The linear torsion set members 54A, 54B, 54C are provided with six receiving flutes 55 to direct the linear structure 1 to accept.

[0080] Furthermore, FIG. 20 illustrates the first example (a select rod system) of the forced transfer means 61 to transfer the wire forcibly near the confounding section, when the linear structure possesses a high stiffness such as a wire, and FIG. 20A is a schematic plan view thereof, and FIG. 20B is a schematic side view seen in the direction of an arrow Y3 in FIG. 20A, and FIG. 21 is a schematic section view showing the main section of the second example (a balloon system) of the forced transferring means to forcibly transfer the linear structure, which possesses a high stiffness such as a wire, near the confounding section, and FIG. 22 is a schematic section view showing the main section of the third example (a cylinder system) of the forced transfer means to forcibly transfer the linear structure, which possesses a high stiffness such as a wire, near the confounding section.

[0081] The forced transfer means 61 by the select rod system shown in FIG. 20 as the first example in the present invention, for instance, is composed of comb blade members 62A, 62B, 62C entering from three directions at intervals of a 120-degree angle. The comb blade members 62A, 62B, 62C, for instance, which are combined on the free end side of the linear structure torsion set members 54A, 54B, 54C shown in FIG. 19, as mentioned in FIG. 20B, certainly allocate respective linear structures 1 to designated sections spaced at a 120-degree angle and twist to entangle said linear structure 1 in such a condition when the comb blade members 62A, 62B, 62C enter (indicated with a an assumed line in FIG. 20B).

[0082] In the forced transfer means 71 which is a balloon system of the second example shown in FIG. 21, for instance, air transport mechanisms 72A, 72B, 72C, composed of the linear structure torsion set members 54A, 54B, 54C shown in FIG. 19, fitted with the air transport mechanisms 72A, 72B, 72C, has air transport paths 73A, 73B, 73C connected to an air supply source (not shown in the drawings), and the air transport paths 73A, 73B, 73C are connected to a crossroad 74 extending in the radial directions in the tip side 73a and send out the supplied air to the air transport paths 73A, 73B, 73C via the crossroads 74A, 74B, 74C. Polyurethane rubber members 75A, 75B, 75C are installed outside of the crossroads 74A, 74B, 74C at each of the linear structure torsion set members 54A, 54B, 54C and composed to be inflated outward by the air transport.

[0083] In accordance with FIG. 21, with reference to the linear structure torsion set member 54B in the center, the air transport mechanism 72B is in the OFF position, and with reference to the linear structure torsion set member 54A, 54C on both sides, the air transport mechanism 72A, 72C are in the ON position. By the inflation of the polyurethane rubber member 75A, 75C, the linear structure 1 as shown in FIG. 21 is pushed to be pressed forcibly into a flute of the linear structure torsion set member 54B and stowed to be supported, surely maintaining the linear structure 1 immediately in front of the torsion section of the linear structure 1. In the case of this embodiment, it is preferable that a gauge member G is set in order to secure clearance between respective adjacent X confounding points.

[0084] Moreover, the forced transferring means 81, the cylinder system of the third example shown in FIG. 22, for instance, is composed of the linear structure torsion set member 54A, 54B, 54C shown in FIG. 19 fitted with cylinder mechanisms 82A, 82B, 82C. The cylinder mechanisms 82A, 82B, 82C comprising collar members 84A, 84B, 84C on the free end side of releases 83A, 83B, 83C, are composed so that the collar members 84A, 84B, 84C come closer or come away along the shaft direction against the linear structure torsion set member 54A, 54B, 54C on the rear end side of the linear structure torsion set members 54A, 54B, 54C.

[0085] In accordance with FIG. 22, with reference to the linear structure torsion set member 54B in the center, the collar member 84B in the cylinder mechanism 82B in a backward position, and with reference to the linear structure torsion set members 54A, 54C on both sides, the collar member 84A in the cylinder mechanism 82A and the collar member 84C in the cylinder mechanism 82C are in the forward position. The linear structure 1 as shown in FIG. 22 is pushed to be pressed forcibly into a flute of said linear structure torsion set member 54B and stowed to be supported, surely maintaining the linear structure 1 immediately in front of the torsion section of the linear structure 1. In the case of this embodiment, it is also preferable that a gauge member G is set in order to secure clearance between respective adjacent X confounding points.

[0086] In accordance with a manufacturing method for a three dimensional structure of the present invention and its manufacturing method, the three dimensional structure is composed on the principle of braid composition, and, a 3X three dimensional structure, a 4X three dimensional structure, and a 6X-3X three dimensional structure may be composed. When these structures are placed in a fluid channel of a distillation device and employed as a filler for a mass transfer, a heat exchange, and so on, a fluid flows from three directions to a junction and flows in three directions in a 3X three dimensional structure, and a fluid flows from four directions to a junction and flows in four directions in a 4X three dimensional structure, and a fluid flows from six directions to a junction and flows in six directions, then each of them respectively separates in three directions to a 3X junction and flows in three directions in a 6X-3X three dimensional structure. It may be said that it acts extremely effectively on the point of the superior processing ability and the improvement of processing efficiency by reduction of a pressure force loss.
