BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of a method and an apparatus for manufacturing a net according to the present invention will be described. First, an apparatus for manufacturing a net will be described, and then a method for manufacturing a net will be described. Further, in each embodiment, the same components are denoted by the same reference numerals, and only different components are denoted by different reference numerals.
[0009]
As shown in FIG. 1, the net manufacturing apparatus 1 includes a mounting table 4 provided on a slide plate 3 of a base 2 at appropriate intervals, and a rotating plate 5 provided on both sides of the base 2 so as to face each other. The horizontal frame member 6 is disposed between the upper portions of the rotary plates 5 and is movable up and down, and the torsion bars 7 are provided on the horizontal frame member 6 at appropriate intervals in a hanging state.
[0010]
As shown in FIGS. 2 and 3, the slide plate 3 is installed over the entire upper surface of the base 2 via a linear bearing 10 composed of a rail 8 and a slide guide 9, and is slid by an air cylinder 11 connected to one end. I can do it. Stands 12 are erected at appropriate intervals on the slide plate 3, and a top plate 13 is fixed to the upper surface of the stand 12 to constitute the mounting table 4. Therefore, a large number of mounting tables 4 are erected on the slide plate 3 with a slight space therebetween, and can be slid in the lateral direction by the air cylinder 11.
[0011]
On the top plate 13 of the mounting table 4, hook pins 14, 15 are erected on the front and rear end sides, and the hook pin 14 on the front end side is erected on the tip of the air cylinder 16, and slides in the long hole 17. I can do it. Therefore, as shown in FIG. 4, the bent portion 19 of the first mountain-shaped row line 18 is hooked on the latch pin 15 on the rear end side, and the second mountain-shaped row line is hooked on the latch pin 14 on the front end side. When the bent portions 21 of 20 are latched, a small loop 22 and a large loop 23 in which the bent portions 19 and 21 overlap each other are formed between the mounting tables 39 and on the mounting table 4. An insertion hole 27 is opened at the center of the top plate 13, and a small mesh hooking pin 28 projects from the top surface of the top plate 13.
[0012]
FIG. 5 shows the mounting table 4 installed at both ends. The toggle clamp 29 of the top plate 13 presses down the ends of the mountain-shaped row lines 18 and 20 hooked to the mounting table 4. Things. Therefore, when the grip 30 is lifted in the upper direction (the direction of the arrow), the holding plate 31 rotates in a direction away from the top plate 13, and when the grip 30 is rotated in the lower direction, on the other hand, the holding plate 31 moves to the top. The end portions of the mountain-shaped row lines 18 and 20 can be pressed by being pressed against the plate 13.
[0013]
The rotating plates 5 installed on both sides of the base 2 are rotated about a shaft 36 by a driving motor 33 (see FIG. 1). As shown in FIG. 6, a horizontal frame member 6 is stretched between the upper portions of the rotary plate 5 via a linear bearing 10 including a rail 8 and a slide guide 9. A connecting member 37 connected to an end of the horizontal frame member 6 is connected to the slide guide 9 of the linear bearing 10, and a tip end of an air cylinder 38 installed on the rotating plate 5 is connected to the connecting member 37. Therefore, the horizontal frame member 6 moves up and down due to the expansion and contraction of the air cylinder 38, and also rotates around the front end with the rotation of the rotating plate 5.
[0014]
As shown in FIG. 6, the torsion bars 7 are provided on the horizontal frame member 6 so as to hang down at appropriate intervals so that the distal end is located between the mounting tables 39. Accordingly, the torsion bar 7 also moves up and down due to the expansion and contraction of the air cylinder 38, and also rotates around the distal end with the rotation of the rotating plate 5. Further, the torsion bar 7 is lifted when the mountain-shaped row lines 18 and 20 are hooked on the mounting table 4, and is lowered after the mountain-shaped row lines 18 and 20 are hooked on the mounting table 4, and the tip end is lowered. Plugged into small loop 22.

Next, a method for manufacturing a net using the above-described net manufacturing apparatus 1 will be described with reference to FIGS. 1 and 7 to 10. First, as shown in FIG. 1, the torsion bar 7 is pushed up and pulled out from the space 39 between the mounting tables. Next, as shown in (1) of FIG. 7, the bent portion 19 is hooked on the locking pin 15 on the rear end side, and the first mountain-shaped row line 18 is set on the mounting table 4. Next, when the bent portion 21 is hooked on the front end side hooking pin 14 and the second mountain-shaped row line 20 is set on the mounting table 4, the small loop 22 and the large loop 23 where the bent portions 19 and 21 overlap each other are set. Are formed between the mounting tables 39 and on the mounting table 4. Next, as shown in (2) of the same figure, the horizontal frame member 6 is lowered and the tip of the torsion bar 7 is inserted into the small loop 22. When the horizontal frame member 6 is rotated by the rotation of the rotating plate 5, the torsion bar 7 is rotated around the tip portion, and the small loop 22 is twisted. Then, after the torsion bar 7 rotates about 180 °, the horizontal frame member 6 is lowered by the air cylinder 38, the tip of the torsion bar 7 is pulled out from the small loop 22, and the rotary plate 5 is rotated in the reverse direction to rotate the horizontal frame. Return the material 6 to its original position (upper side).
[0016]
Next, the torsion bar 7 is lowered by the same operation as described above, and its tip is inserted into the small loop 22 and rotated in the same manner as described above. When this operation is repeated several times, a small mesh 24 and a large mesh 25 are simultaneously formed as shown in FIG. When the small loop 22 is twisted to form the small mesh 24 and the large mesh 25 in this manner, the tension of the large mesh 25 increases, and the small mesh 24 cannot be pulled out from the hook pins 14 and 15. Then, as shown in (2) of the figure, if the tension of the large mesh 25 is weakened by sliding the front end side locking pin 14 with the air cylinder 16, the large mesh 25 is pulled out from the locking pins 14 and 15. Becomes possible. The small mesh 24 and the large mesh 25 can be formed by twisting with the torsion bar 7 inserted into the small loop 22 or by twisting the small loop 22 with a sandwiching plate.
[0017]
Next, as shown in (1) of FIG. 9, the horizontal frame member 6 is lifted by the air cylinder 38, and the torsion bar 7 is pulled up from the space 39 between the mounting tables. Then, the toggle clamp 29 of the mounting table 4 at both ends is loosened, the mesh wire 26 formed with the small mesh 24 and the large mesh 25 is pulled out from the hook pins 14 and 15, and the mounting table 4 is held by the air cylinder 11. It is moved to a position directly below the torsion bar 7, that is, a position where the small mesh 24 is formed. Then, as shown in (2) of the figure, when the small mesh 24 is hooked on the retaining pin 28 for the small mesh, the large mesh 25 comes to be located between the mounting tables 39.
[0018]
Next, the mounting table 4 is moved to the original position, that is, the position where the torsion bar 7 is located between the mounting tables 39 by the air cylinder 11. Then, as shown in (1) of FIG. 10, when the bent portion 40 is hooked on the hook pin 14 on the front end side and the third mountain-shaped row line 41 is set on the mounting table 4, the bent portion 21 of the large mesh And a small loop 22 in which the bent portion 40 of the mountain-shaped row line 41 overlaps is formed between the mounting tables 39. Then, the small loop 22 is twisted in the same manner as described above to form a small mesh 24. By repeating such operations sequentially, a net 42 as shown in FIG. This mesh body 42 has small meshes 24 formed at the entangled portions of the large meshes 25, and has meshes 23 and 24 of different sizes.
[0019]
FIG. 11 shows a mesh body 43 in which the small meshes 24 are perpendicular to the large meshes 25, and this mesh body 43 is manufactured in substantially the same manner as described above. FIG. 12 shows the manufacturing method. As shown in (1), the rotation of the torsion bar 7 is made more or less than the above, and the vertical mesh 24 is formed. Next, as shown in (2), the mesh wire 26 pulled out from the hook pins 14 and 15 is set on the mounting table 4 by the same method as described above, and the vertical small mesh 24 is inserted into the insertion hole 27. Then, the third mountain-shaped row line 41 is set on the mounting table 4 in the same manner as described above to form the small loop 22 and the large loop 23. The small loop 22 is twisted to form the vertical small mesh 24 with the horizontal small mesh 24. A large mesh 25 is formed (not shown). By repeating such operations sequentially, the net 43 shown in FIG. 11 is manufactured.
