Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a knotless net weight distribution device that allows a larger strand winding diameter to be obtained compared to the conventional twin knotless net knitting method.

The conventional twin knotless braiding method involves arranging three spindles with four notches for transferring the strands in a straight line in the order of twisting ring → braiding ring → twisting ring at 180 degrees. Place a pair of strands a and b in one twisting ring, and place the other pair of strands c and d in the other twisting ring so that the phase between the pairs is 90°.
After the twisting process is completed, strands a and b are replaced with strands c and d, and then strands are braided. For example, the one shown in Fig. 1 is a conventional braiding device with penetrating knots, in which A ₁ and A ₂ are twisted rings, B is a braided ring, a, b, c, and d are strands, and they are rotated by 90 degrees. As one process, the knots are braided in steps (1) to (13), but in this braiding method, the two strands are placed in adjacent notches on the same ring, so the strands are stored. Because the diameter of the tsum can only be 0.7 times the diameter of the ring's pitch circle,
This method has the disadvantage that the amount of winding of the strand is small, the strand replacement cycle becomes early, and the operating rate of the braiding device decreases.

In addition, Figure 2 shows the method for transferring strands using the method shown in Japanese Patent Application Laid-Open No. 52-59758.
Two stranded wheels A ₁ A ₂ with two notches, two auxiliary wheels C ₁ , C ₂ and one assembled ring B are combined into a stranded ring A ₁ → auxiliary wheel
C ₁ Set of wheels B → Auxiliary wheel C ₂ → Twisted ring A ₂ → A pair of strands a and b arranged in a straight line so that each other has a phase of 180 is attached to one twisted ring A ₁ between the pair. Place the other strands c and d on the other twisting ring _A2 so that the phases of the two strands are 180° with respect to each other, and rotate 90° in one turn.
This is a method of braiding in steps (1) to (15).
However, in this case, the phase between the closest strands during the braiding process is 180°, so the diameter of the thread can be made close to the pitch circle diameter of the spindle, but in order to enable continuous rotation, it is necessary to A complicated mechanism is required in which the rotation of wheel B is 1/2 times the rotation of twisting wheel A and auxiliary wheel C.

Furthermore, Fig. 3 shows the method disclosed in Japanese Patent Application Laid-Open No. 52-59758, in which five spindle wheels each having two notches for transferring the bobbin are twisted from twisting wheel A ₁ to auxiliary wheel C ₁ .
→ Grouped ring B → Auxiliary wheel C ₂ → Twisted ring A _{A pair of strands a} and b arranged in a straight line with each other at a phase of 180°
is placed on one twisting wheel _A1 , and another pair of strands c and d, whose phase is 180° to each other, is placed on the other twisting wheel _A2 , and rotation by 90° is regarded as one step.
This is a method of loop braiding in steps (1) to (11), but according to this method, the phase between the closest strands in the braiding process of the knots is 180°, so the diameter of the loop is the same as the pitch circle of the spindle. It is possible to get close to the diameter of the twisted ring.
Since it is necessary to operate a 1/2-turn clutch at A ₁ and A ₂ , the mechanism is complicated and it has the disadvantage that continuous rotation is not possible.

The symbol △ in the figure indicates clutch operation.

Furthermore, FIG. 4 shows a method disclosed in Japanese Patent Application Laid-Open No. 118936/1986, in which five large unloading weight rings, or twisting rings, each having two notches for transferring the strands are used.
A ₁ , A ₂ set of wheels B, auxiliary wheels C ₁ , C ₂ have a pitch circle diameter that is 1/2 times the pitch circle diameter of this large luck spindle, and have two notches for transferring the strands. There are two small auxiliary wheels D _{1 and} D 2 that have twice the angular velocity as the large auxiliary spindle, a total _{of seven auxiliary wheels D 1 →}
Twisted wheel A ₁ → Auxiliary wheel C ₁ → Grouped ring B → Auxiliary wheel C ₂ → Twisted wheel A ₂
→ Small auxiliary wheel D ₂ → A pair of strands a and b with a phase of 180 degrees to each other is arranged in a straight line on one twisting wheel A ₁ , so that the phase between the pair of strands is 180 degrees. Then tie another pair of strands c and d to the other twisting ring.
This is a method in which the knots are braided in steps (1) to (11), with 90° rotation being placed in A ₂ as one step. However, according to this method, a total of seven weight wheels are required, so although continuous rotation is possible, the entire device becomes large in size.

FIG. 5 shows a weight distribution device disclosed in Japanese Patent Application Laid-open No. _56-118936 , which uses the same weight wheel as shown in _FIG . Analyze this braiding method using a weight distribution device in which braided ring B → auxiliary wheel C ₂ → twisted ring A ₂ → small auxiliary wheel _{D 2} are arranged in a straight line, and another twisted ring A ₁ is connected at right angles to auxiliary wheel C 1. Then, the knots can be continuously braided in steps (1) to (13) with 90° rotation as one step, but the drawback is that the number of braiding steps is greater than in FIGS. 3 and 4.

Therefore, this invention is a knotless net weight distribution device that allows the diameter of the bobbin-accommodating bobbin to be brought closer to the diameter of the spindle, reduces the size of the entire device, reduces the number of braiding steps, reduces continuous rotation, and enables continuous rotation. This is what we are trying to provide.

In other words, as shown in Fig. 6, twisting wheels A ₁ and A ₂ each have four notches for transferring the strands.
The strands B ₁ and B ₂ have a pitch circle diameter 1/2 that of the twisting ring (and the strand ring), have an angular velocity twice that of the twisting ring, and have two points for transferring the strands. A total of six spindles, small auxiliary wheels D ₁ and D ₂ with notches, are connected to the small auxiliary wheel D ₁ → Grouped ring B ₁ → Twisted ring A ₁ → Grouped ring B ₂ → Twisted wheel A ₂
→ Pair two strands that are arranged in a straight line with the small auxiliary wheel D ₂ and have a 180° phase with each other, and make both twisted wheels A so that the two pairs of strands a, b, c, and d maintain a 180° phase with each other. When one pair is placed in each of ₁ and A ₂ as a knitting unit of knots, and a 90° rotation is considered as one process (1)
~ (11) It is something that is continuously braided in the process. The transfer of the strand from one spindle to another via an on-off valve is conventional, and is therefore not shown. FIG. 7 shows connecting rings E ₁ and E ₂ that have four notches for transferring the strands to the braided unit explained in FIG. 6 and have the same angular velocity as the twisted rings (and braided rings). This is a weight distribution device connected to each of the twisting wheels A ₁ and A ₂ at right angles. A, b, ha, d,
Ho, He, are the respective strands a ₁ , b ₁ , c ₁ ,
This is a net leg consisting of d ₁ , a ₂ , b ₂ , c ₂ , d ₂ , a ₃ , b ₃ , c ₃ , d ₃ , indicating that this net leg is arranged in a meandering manner as a whole. . α, β, and γ are the braiding units of the knots. FIG. 8 shows the position of the strands after being changed for braiding and the position of each strand after being transferred to the twisting wheel. In other words, 1 is the state in which the twisting process has been completed, and 2 is the net legs A and B, C and D,
3 is a state in which the strands of the net legs A, H, H, and G are each transferred to the twisted ring on the braided unit on the right side, 4
After twisting in state 3, the net leg B and other net legs (consisting of strands expressed without reference numbers in Figure 8), A and D, H and H, H and CH, and T. 5 is a state in which the strands of the other net portions have been replaced, and 5 is a state in which net portions B, D, F, and H are transferred to the twisted ring on the adjacent braid unit on the left. The state of the net braided in this manner is as shown in FIG. 9. FIG. 10 shows a different arrangement of connecting rings from that shown in FIG. 7, and α', β', and γ' are different braid units.

As described above, according to the present invention, since the weights can be arranged in a meandering manner, the entire apparatus can be made smaller, and the process of braiding the knots can be reduced to enable continuous operation.
