Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a knitting machine and a knitting method for knitting a three-piece knotless net.

Conventionally, in knotless nets, one or three strands are twisted to form the legs of the net, and the intersections are, for example,
1/-21037, since the strands are not intersected in a precise manner, as proposed by No. 1/21037.
When the net is broken, the twists are easily untwisted, which has a large effect on the other wires, causing the net to be easily damaged, and the intersecting portions are also easily loosened and deformed.

This invention was created in order to solve the above-mentioned drawbacks, and it is possible to efficiently knit a three-strand knotless net by machine knitting, which is difficult to untwist and expand the broken area when the net is broken. The purpose is to provide a netting machine and a netting method.

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a mid-longitudinal sectional view of the upper part of the knitting net machine, and FIG. 1 shows a partial plan view of the same net machine. Knitting Machine Co., Ltd. engages a large number of radially arranged shuttles with the Tonari-gumi-unweight wheel and the group-unweight wheel 3 installed inside a cylindrical side control, and rotates the shuttles while drawing a constant trajectory. While moving, each shuttle/
The strands are pulled out from the tip of the net to knit a three-strand knotless net. FIG. 3 shows the front arrangement of the adjacent group weight wheel λ and the group weight wheel 3 that support and move the shuttle l. A large number of spindles are supported by bearings at regular intervals circumferentially, and a drive gear j is attached to the outer end of each spindle. are the adjacent gears j
In addition, a specific spindle is connected to a rotational drive device, and all spindles are configured to be rotationally driven in a predetermined direction. - The Tonari-gumi Unkei wheel is made up of two spindle wheels that rotate in opposite directions, which are pivoted on a single spindle arranged in one row above and below. As shown in FIG. 3, the spindle wheels 3 forming the spindles are successively arranged as shown in FIG. 3, and each spindle wheel is driven to rotate in a predetermined direction by a spindle reference. Furthermore, there are 6
Six retaining parts Ja, Ja are formed at 0 degree intervals, and a supporting weight attached to the end of the shuttle l is engaged with these engaging parts, 2a, Ja, and each supporting weight is Fortune wheel 2
It rotates while drawing a predetermined locus from 3VC, and operates so as to be transferred to the adjacent set-up spindle wheel or set-up weight wheel 3 by the operation of the on-off valve 7 which is connected to and operated by a jacquard device (not shown). . In addition, the opening/closing valve 7 is placed in the vicinity of the neighboring group weight ring 2 and group weight ring 3, and the supporting weights (A+~AJ, river~BI) that have been moved here! It is pivotally supported so as to be able to swing so as to be transferred to the adjacent adjacent set weight wheel or set weight wheel 3, and is operated at a predetermined tie ring by driving from a jacquard device. In addition, a pull-out device (not shown) for pulling out a net knitted by strands pulled out from the shuttle l is installed below the tip of the radially arranged shuttles l.

Next, a method of knitting a three-piece knotless net using the knitting machine with the above configuration will be explained using the support spindles A1 to As e in FIGS. 4 and 5.
This will be explained with reference to the locus diagrams of B1 to B. ◎First, since three strands form a set to form the legs of the net, the supporting spindles of the three shuttles IS// and the seven sets. As a result, as shown in the top row of FIG. 4, the engaging portions 2aK of the adjacent weight wheels on both sides are engaged at regular intervals. Then, when the two spindles of the adjacent spindle λ are rotated in opposite directions,
Engagement part - aK Three engaged support spindles A1 to AI or Ji
B+~B, is the 4th! A Kf-shaped movement is performed as shown in the locus diagram in the figure. In other words, the supporting spindles A1~^, B1~B1 that come close to the two upper and lower weight wheels rotate and move so that they are always transferred from top to bottom or from bottom to top. The legs of the net are formed by intersecting each other, and the three strands 01 to CI or 3 to Di are assembled to form the legs of the net (No. JyJ).

Next, when the on-off valves 7 provided close to both sides of the assembly weight wheel 3 operate due to the operation of a jacquard device (not shown), the valves 7 engage with the adjacent assembly weight wheels 3 on both sides and perform an L-shaped 4 movement. Each of the three supporting weights A1 to A, , B, to B are the group-un weights 3.
When approaching the point where it approaches the adjacent grouping weight wheel 2, the engagement part jaK of the grouping weight wheel 3 changes one by one, making a half turn due to the rotation of the grouping weight wheel 3, and then approaches the adjacent grouping weight wheel 2 on the opposite side. 7 to the engaging portion 2a of this spindle wheel by the operation of the on-off valve 7 at the location.
Can be changed one by one. Such supporting spindles A1 to AI,
B.

~Bl is alternately moved via the assembly weight wheel 3, so that each shuttle l intersects while changing its trajectory, and as shown in the figure, each strand C1~Cs, DI-DI is assembled alternately. A mesh intersection is formed.

Next, the supporting spindles A1 moved to the neighboring group un weight wheels 3' on both sides.
Bunsha B1 to EIFi, again as shown in FIG. 4, the two spindle wheels perform a T-shaped movement as the two spindles rotate, and the shuttle l performs a similar movement to form the legs of the net. After the legs of a certain length are formed, the support spindles A1 to Asa that are engaged with the adjacent group weight wheel between the centers 7 are moved to the next neighboring group weight wheel - through the group weight wheel 3 on the right side. Instead, the supporting weights B1 to B engaged with the left leg weight wheel 2 are transferred to the next leg weight wheel λ via the group weight wheel 3 on the left side, and the same operation is repeated. As a result, a three-piece knotless net is knitted.

As described above, according to the three-piece knotless net knitting machine and the knitting method according to the present invention, the set unloading weight ring is placed between the leg unloading ring consisting of two unloading weight rings. 1. Engage the three shuttle spindles with the retaining parts provided on these spindles, and rotate the spindle of one of the leg spindles to make the spindle into a T-shape. The legs of the net are formed by movement, and the supporting weights, which are engaged with the leg weight rings on both sides, are transferred via the grouping weight rings to form the intersecting parts of the net, thereby forming a three-piece set without knots. Since the net is constructed to be knitted, compared to conventional two-strand or three-strand knotless nets, it is possible to efficiently knit a durable net with less impact on other parts when the net breaks, by machine knitting. can. In addition, compared to a two-strand knitting machine, the number of gold threads in each strand can be reduced in the case of a net of the same thickness, so the spring amount of the bobbin in the shuttle increases, and the knitting machine itself also This has advantages such as miniaturization.
