Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a net-making method for making a knotless net and a net-making machine for carrying out the method.

<Conventional technology> Conventionally, a normal two-strand knotless net using a penetrating cross has two twisting weight wheels with four engaging parts and a pairing ring with the same number of engaging parts that rotates counterclockwise. Two weight wheels are arranged alternately, and a shuttle is held on each weight wheel.
The net is knitted by a knotless net making machine in which different supporting weights are engaged, while moving the supporting weights, that is, shuttles, as shown in the supporting weight transition locus diagram in FIG. 5. That is, first, the supporting spindle engaged with the left twisting weight ring 11
A ₁ and A ₂ sequentially move to group weight 13, and then
The supporting weights B ₁ and B ₂ engaged with the right twisting weight wheel 12 are transferred to the setting weight wheel 13 . Then, the support spindle A ₁ rotates once together with the right twisting weight wheel 12 and moves to the setting weight wheel 13, and then again transfers to the right twisting weight wheel 12 after rotating once here. On the other hand, the support spindle B ₁ moves to the grouping weight wheel 13, rotates 11/2 times together with the grouping weight wheel 13, and then moves to the left twisting weight wheel 11, whereby each of the weights 11, 12, 13 is rotated 2 3/4 times to form the intersection of each strand.

<Problems to be Solved by the Invention> However, when making a knotless net using the conventional net making machine and method as described above, there was a problem in which it was difficult to improve productivity.

In other words, in this type of conventional net making machine, the spindle wheel is generally driven to rotate at about 85 rpm, but in this case, the time required for one rotation of the spindle wheel is about 0.7 seconds. Since on-off valves are arranged at four locations around the assembly weight wheel, which has four engaging portions, the opening and closing operations of the on-off valves are performed in 0.17 seconds. Therefore, increasing the rotational speed of the spindle wheel any higher than this will interfere with the smooth operation of the on-off valve and may cause a breakdown, so increasing the rotational speed of the spindle wheel will increase the productivity of the net. I had a difficult problem.

<Means for Solving the Problems> The present invention has been made to solve the above problems, and improves the hourly production of knotless nets, that is, productivity, without putting a burden on the net making machine. The purpose of the present invention is to provide a net making method and a net making machine thereof, which are configured as follows.

The twisting weight wheel is configured to rotate in opposite directions at twice the rotational speed of the tying weight wheel.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

First, I will explain the outline of the knotless net making machine.
Figure 1 shows the arrangement of a set of spindle wheels.

One set of spindles includes two sets of spindles 1, 2 and two twisted spindles 3, 4 arranged adjacent to each other alternately, and each spindle is supported by a spindle (not shown). The grouping weight wheels 1 and 2 rotate at a constant speed in the clockwise direction in FIG.
It is rotated at twice the rotational speed. The assembly weight wheels 1 and 2 have a diameter approximately twice that of the twisting weight wheels 3 and 4, and four engaging portions 5 are provided at 90 degree intervals on their outer peripheries. Two engaging parts 6 are provided at 180 degree intervals on the outer periphery of the 1/2 diameter twisting weight wheels 3 and 4, and the engaging parts 5 and 6 have supports attached to the base of the shuttle. Weights A ₁ , A ₂ , B ₁ , and B ₂ are engaged.

The shuttle's supporting weights A ₁ , A ₂ ,
The on _- off valves 7 _, 8,
9 is provided.

These on-off valves 7, 8, and 9 operate in conjunction with a gear guard device (not shown), and operate to move the supporting weight between adjacent spindle wheels at a predetermined timing.

A bobbin wound with strands is stored in each shuttle, and a large number of sets of twisting weight wheels 3, 4 and grouping weight wheels 1, 2 are arranged consecutively, for example, on a cylinder, and each of the twisting weight wheels The shuttles, each of which has a supporting weight engaged with the engaging part, are arranged radially, and the strands are pulled out from the tips of the numerous shuttles by an unillustrated feeding mechanism during the twisting process, and the knotless net is knitted. The net making machine is configured to do this.

Next, a method of making a two-strand knotless net using the net making machine having the above configuration will be explained with reference to a support spindle transition trajectory diagram in FIG.

Figure 2 shows one crossing process that is carried out after the twisting process in which two strands are twisted to form the legs of the net, and each step from 1 to 9 consists of the twisting weight wheel 3,
4 rotates 180 degrees, and the positions of the supporting weights A ₁ , A ₂ , B ₁ , B ₂ are shown over time each time the assembly weight wheels 1 and 2 rotate 90 degrees.

First, a pair of supporting weights A ₁ are attached to one twisting weight ring 3,
A ₂ is engaged, and a pair of supporting weights are attached to the other twisting weight ring 4.
From the state in which B ₁ and B ₂ are engaged and the support weights A ₁ , A ₂ , B ₁ , and B ₂ are located in a straight line, the support weight A ₁ is transferred from one twisting weight ring 3 to one set weight. Moves to ring 1, moves from the grouping weight wheel 1 to the other grouping weight wheel 2 via the other twisting weight wheel 4, then moves to the other twisting weight wheel 4, and the supporting weight A ₂ After rotating one of the twisting weight wheels 3,
It moves to the other twisting weight wheel 4 via one of the twisting weight wheels 1 and rotates, and after the supporting weight B ₁ rotates with the other twisting weight wheel 4, The support spindle B ₂ moves to the other twisting weight wheel 2 and then moves to one of the twisting weight wheels 1 via the other twisting weight wheel 4. Move, and at this time, the supporting spindle
A ₁ and B ₁ are shifted to intersect at the other twisting weight ring 4 (steps 3-4), and the supporting weight A ₂ and
B ₂ moves to intersect at the other twisting spindle 4 (steps 6-7), causing the two pairs of strands to intersect, and then the pair of supporting weights A ₁ and A ₂ intersect at the other twisting spindle 4. The supporting weights B ₁ and B ₂ rotate on one of the twisting weight wheels 3 to twist the two pairs of strands.

That is, to explain based on FIG. 2, first, the shuttle spindle A ₁ that engaged with the left twisting weight wheel 3 in step 1 moves to the twisting weight wheel 1, and rotates at 90 degrees with the twisting weight wheel 1. Rotate. On the other hand, the shuttle spindles B ₁ and B ₂ engaged with the right twisting weight ring 4 rotate 180 degrees there. Then, in steps 2 and 3, the shuttle spindle _B2 , which was engaged with the right twisting weight wheel 4, is transferred to the right twisting weight wheel 2, and in steps 3 and 4, it is transferred to the left twisting weight wheel 1. The shuttle spindle A ₁ that was engaged is transferred to the twisting weight ring 4 .

Next, in steps 4 to 5, the shuttle spindle B ₁ that was engaged with the right twisting weight wheel 4 is transferred to the left twisting weight wheel 1, and the supporting weight A ₁ is transferred to the right twisting weight wheel 2. Move to. Then, in steps 5 and 6, the support weight _B1 , which was engaged with the left twisting weight ring 1, is transferred to the left twisting weight ring 3.
, the supporting weight A ₂ is transferred to the twisting weight ring 4 on the right side,
The support spindle B ₂ that was engaged with the right-hand twisting weight wheel 2 is transferred to the right-hand twisting weight wheel 4.

Subsequently, in steps 6-7, the support spindle _B2 , which was engaged with the twisting weight wheel 4 on the right side, moves to the twisting weight wheel 1 on the left side, and in steps 7-8, it moves to the twisting weight wheel 2 on the right side. The engaged supporting weight A ₁ moves to the twisting weight ring 4 on the right side,
Further, in steps 8 to 9, the support spindle B2, which has been engaged with the left-hand twisting weight wheel _1, is transferred to the left-hand twisting weight wheel 3, and the crossing process is completed.

In this way, the shuttle weights A ₁ , A ₂ and the support weights B 1 , B ₂ of the shuttle, which were engaged with the left and right twisting weight wheels 3 and _4,
first moves to the right-hand grouping weight wheel 1 or 2, respectively, and crosses through the twisting weight wheel 4 on the right side (the twisting weight wheel located between the two grouping weight wheels 1 and 2). , and finally move to the twisting weight ring on the opposite side. Due to the movement of the two pairs of shuttle spindles A ₁ , A ₂ , B ₁ , and B ₂ , one crossing portion is formed by the two pairs of strands pulled out from the shuttle. In addition, 1 to 9 above
In steps 1 and 9, steps 1 and 9 can enter the twisting process, so the actual crossing process is carried out in 7 steps, which is much better than the conventional net making method shown in Figure 5. This means that the intersection can be created with a small number of steps.

Following the above-described crossing process, a twisting process is performed, and the pair of shuttle spindles A ₁ , A ₂ or B ₁ ,
By rotating the twisting weight wheels 3, 4 on both sides that engage _B2 , a pair of strands from each shuttle is twisted to form the legs of the net. At this time, the twisting weight wheels 3 and 4 rotate at twice the rotational speed of the grouping weight wheels 1 and 2, so compared to the conventional device that rotates at the same speed as the grouping weight wheels, twisting takes half the time. process can be carried out.

The knotless net made by the above-mentioned process is shown in FIGS. 3 and 4, and is similar to the net made by the conventional process shown in FIG. 5. That is, strand C ₁ passes above strand D _{1 and} below strand D ₂ , strand C ₂ passes below strand D ₁ and above strand D ₂ , and strand D ₁ passes below strand C 1 and above strand D ₂ . _{Strand D 2 passes} over strand C ₁ and under strand C ₂ to form a crossover.

<Effects of the Invention> As explained above, according to the knotless netting machine of the second invention, a pair of assembly weight wheels having four engaging parts and a pair of assembly weight wheels having two engaging parts are provided. Since the pairs of twisting weight wheels are arranged adjacent to each other alternately, the twisting weight wheels are
It can be rotated at twice the rotational speed, and the twisting process can be performed in half the time compared to conventional methods.

Further, according to the net making method of the first invention, the supporting spindle
In order to intersect the two pairs of strands, A ₁ and B ₁ are shifted to intersect at the twisting weight wheel 4, and support weights A ₂ and B ₂ are shifted to intersect at the twisting weight wheel 4. , it is possible to make nets with fewer steps than in the past, and the amount of nets produced per hour can be increased.
