Description

TECHNICAL FIELD The present invention relates to a knot forming method that enables various mesh shapes in a knotted mesh, a method for manufacturing the same, and a knitted mesh apparatus.

Conventional knotted knitting devices are occupied by those that perform knitting using frogmata or main knots. Especially in knitted nets of general knotted nets, the frog or knot knitted net device is widely used because of the advantage that the knots are less likely to be misaligned compared to the main knots. As shown in FIG. 2(A), any of the knitting net devices employs a knotting method in which a bobbin shuttle 13 containing weft yarns 15a is passed through a knotting loop made of warp yarns 14a. Possible knotting techniques are limited to the frogmata or honme shown in FIG. 2(B), or variations thereof. Further, in the conventional knotted knitting net device, the knot spacing is adjusted by feeding a fixed length of stitches according to the mesh size in the stitch feeding mechanism including the yarn swinging frame 17 . An example of a recent knotted knitted mesh device and a knitted mesh method using the same is given in Patent Document 1.
These knitted net devices have been developed for the limited application of manufacturing knotted fishing nets. ing. For this reason, it is difficult to adapt to a mesh shape suitable for a new application, such as a regular hexagonal mesh (Patent Document 3) for the purpose of preventing wild birds from stalking.

On the other hand, conventionally, in the production of tortoiseshell netting using metal wires, a method has been adopted in which a wire is pulled out from a bobbin in a fixed direction, and the two wires are twisted together by hanging them on a pin on a knitting net roller to create a mesh. In recent years, a tortoiseshell mesh manufacturing apparatus using hard plastic wire rods (Patent Document 2) has also been used. However, due to the nature of the material, it is not possible to form a knitted net with looped knots.

In traditional handicrafts such as macrame, there are knitted netting techniques that combine various knotting techniques and mesh adjustment, and various netting and knitted fabric interiors and personal items are produced. However, most of them are limited to small items made by hand, and industrial production of land nets using a knitting machine is hardly performed.

FIG. 1 shows the basic configuration of an embodiment of a knotted mesh device of the present invention.
In the bobbin mechanism of the knotted knitting net apparatus according to one embodiment of the present invention, the bobbins 3 prepared according to the number of meshes to be knitted are pulled out on the bobbin rack 6 so as to pull out the net yarn 12 in the knitting direction. The bobbin gauges 5 are arranged at regular intervals, and are provided with grooves for passing the net yarn 12 in accordance with the arrangement of the bobbins 3.例文帳に追加
The knotted loop forming mechanism of the knotted woven net apparatus according to one embodiment of the present invention includes a mesh form 1 combining a mesh form plate 18 having knot guide pins 19 arranged in accordance with the shape of the mesh to be formed, and a bobbin gauge. A knot guide hook 4 arranged according to the scale width of 5, a knot guide pin 19 and a knot guide hook on a mesh form plate 18 arranged at a knot loop forming position by scooping the net thread 12 pulled out from the bobbin 3. It consists of a knotted arm 2 that operates between 4 to form a knotted loop for the desired knotting technique.
The bobbin operation mechanism of the knotted netting apparatus of the embodiment of the present invention includes a bobbin arm 8 for picking up the bobbin 3 on the bobbin rack 6 and passing it through the knotted loop, and an extra arm used for the knotted loop. A knitting yarn 12 is unwound from a bobbin 3 and converged around a knot guide pin 19 to form a temporary knot.
The mesh completion mechanism of the knotted knitted netting apparatus according to the embodiment of the present invention removes the temporarily knotted mesh from the mesh form plate 18 moved to the mesh removing position on the mesh form 1, and pulls the knotted part. It is composed of a mesh adjusting device 9 for squeezing to complete knots and adjusting the mesh, and a mesh winding device 10 for incorporating the adjusted mesh into the mesh 29 and winding it.

The arrangement of each device constituting the bobbin mechanism will be described.
The bobbins 3 on the bobbin rack 6 are installed at a position lower than the knot guide hook 4 and the bobbin gauge 5 at equal intervals so as to match the scale of the bobbin gauge 5, and the knot guide hook 4 is moved to the rear of the bobbin rack 6 to perform the knot. The mesh thread 12 on the side of the knotted guide hook 4 of the knotted loop is passed over the bobbin 3 when the loop is expanded (Fig. 6). The bobbin 3 draws out the net yarn 12 in a fixed direction so that the winding direction of each net yarn 12 matches the rotation method of the net yarn winding device 7 . The upper part of the bobbin gauge 5 is made to have a smooth curved surface so that the mesh yarn 12 does not get caught when it passes.

Among the devices constituting the knot loop forming mechanism, the mesh formwork 1 will be described.
As shown in FIG. 3, on the upper b of the mesh mold 1, the spacing 20a of the horizontal arrangement grid 20 of the knot guide pin 19 is adjusted to match the gauge width 5a of the bobbin gauge 5, and the vertical width is adjusted to match the shape of the mesh. A mesh formwork plate 18 is installed. Polygonal prisms formed by combining a plurality of mesh form plates 18 and mesh form plates 18 having a function of dynamically adjusting the arrangement of knot guide pins 19 are prepared in accordance with the shape of the mesh to be knitted. . The net yarn 12 pulled out from each bobbin 3 through the yarn opening of the bobbin holder 11 passes through a bobbin yarn gate on the bobbin gauge 5 and is guided to a predetermined position on the mesh formwork 1 (Fig. 4). The knot loop forming operation is carried out around the knot guide pins 19 on the mesh form plate 18 which is placed on top of the mesh form 1 .

For example, when knitting a net of regular hexagons shown in FIG. (Fig. 3). The vertical width of the regular hexagonal vertical lines of the mesh form plate 18a corresponds to the length of one side of the regular hexagon, and the vertical width of the diagonal line mesh form plate 18b corresponds to the length of one side of the regular hexagon and the bobbin gauge 5. Calculated from the scale of . A bobbin 3 is passed through a knotted loop created on a mesh formwork 1, and a net thread 12 is rewound onto the bobbin 3 to converge the knotted loop. It is formed. The vertical width of the mesh formwork plate 18 is calculated in consideration of the margin of the temporary knot portion. In addition, selvage knot guide pins 19b can be arranged at the ends of the mesh form plate 18 in order to treat the selvage portion of the mesh fabric.

The mesh formwork 1 can also be used in combination with mesh formwork plates 18 corresponding to different meshes, such as a combination of meshes and regular hexagons. In addition, an auxiliary guide pin can be arranged separately from the knot guide pin 19 at the knot point, and a cloisonné knot can be woven. Further, a knotting guide pin 19b for the selvage thread can be arranged at the end position of the mesh form plate 18. As shown in FIG.

A knitting process using a knotted knitting machine that is an embodiment of the present invention will be described.
FIG. 4 shows the basic arrangement of the bobbin 3 and bobbin gauge 5 for one mesh unit, the knot guide hook 4, the mesh form plate 18 and the knot guide pin 19 at the knot loop forming position on the mesh form 1 in the knot preparation process. shown in The net yarn 12 pulled out from the bobbin 3 passes through the bobbin yarn opening on the bobbin gauge 5 while maintaining an appropriate tension, passes beside the knot guide pin 19 of the mesh formwork plate 18 at the knot loop forming position, and reaches the front stage. The knot guide pins 19 on the mesh form plate 18 used in the formation of the knot loops in FIG.
In the knot preparation step, the above arrangement setting is performed for one stage of the mesh to be knitted.

5 and 6 show an example of operation for forming a knot loop in the knot loop forming step.
The knot arms 2 are knotted between the knot guide pins 19 on the mesh form plate 18 arranged at the knot loop forming position of the mesh form 1 and the knot guide hooks 4 arranged on the bobbin gauge 5. 12 is scooped (Fig. 5), and while pulling out the net thread 12 from the bobbin 3, it is wound around the knot guide pin 19 and the knot guide hook 4 in accordance with the desired knotting technique to form a knotted loop (Fig. 6). This knot loop forming operation is performed for one mesh stage.
The knotting arm 2 allows the thread to pass through as many knotting guide hooks 4 as the number of bobbins the knotting loop passes through plus one (Fig. 6). For example, when making a knotted loop for passing through two adjacent bobbins 3, the net yarn 23 is hung on the three knotted guide hooks 4 on both sides and between the two bobbins. When only one bobbin is passed through, the net thread 22 is hung on the knot guide hooks 4 on both sides of the corresponding bobbin.
After the knot loop is formed between the knot guide pin 19 and the knot guide hook 4, the knot guide hook 4 is moved backward to enlarge the knot loop so that the bobbin 3 can pass through the knot loop (Fig. 7 ( A)).

FIG. 10 illustrates the basic shape of the knotted loop to be formed.
FIG. 10(A) shows the shape of the knotted loop forming an open knot in which the bobbin does not pass through the knotted loop formed by the net yarn 12 pulled out from the bobbin 3 . For example, the bobbin 3b is passed through a knotted loop 25a formed of net thread 22a, or the bobbin 3a is passed through a knotted loop 25b formed of net thread 23a. The frog or knot shown in FIG. 2(B) is an open knot formed by passing the weft 15b through the knot loop formed by the warp 14b.
FIG. 10(B) shows the shape of a knotted loop forming a closed knot that passes through the knotted loop formed by the net yarn 12 pulled out from the bobbin 3 . For example, passing the bobbin 3a through the knotted loop 25c formed by the thread 22a or passing the bobbin 3b through the knotted loop 25d formed by the thread 23a results in a closed "hard knot" knot.
Various knotting techniques can be implemented by combining the basic shapes of these knotting loops and adjusting the number and arrangement of bobbins to be passed through.
For example, in order to form a knot corresponding to the regular hexagonal knot 24a in FIG. 9(A), which is shown in FIG. A knotted loop 25c is formed from the starting position 26c of the bobbin 3a. In order to form a knot corresponding to the regular hexagonal knot 24b of FIG. 9(A), which is shown in FIG. 9(C), the bobbins 3a and 3b are passed through the knot loop 25d, and the net thread 22a is scooped to form a knot. A nodule loop 25c is formed from the loop start position 26a to pass through the bobbin 3a.

The knotted arm 2 grasps the positions of the knotted guide pin 19 and the knotted guide hook 4 based on the bobbin gauge 5, and forms a knotted loop according to the desired knotting technique. The formation loop formation operation is determined by factors such as the basic shape of the knotted loop shown in FIG. The knotted loop forming operation of the knotted arm 2 may be digitized and controlled by a computer.
The knotted arms 2 may be prepared as many as the knotted loops to be formed in one stage, or one knotted arm may be used to form knotted loops for one stage.
The knotted loop forming operation of the knotted arm 2 does not need to be common for one stage of mesh. Multiple knot loop forming operations can be incorporated.

FIG. 7 shows an operation example of the bobbin 3 in the temporary knot network forming process.
The knotted loop formed in the knotted loop forming step is expanded by pulling the knotted guide hook 4 backward, and the bobbin 3 can be passed through as shown in FIG. 7(A). In this state, the bobbin arm 8 is inserted into the bobbin rack 6 to pick up the individual bobbins 3 and pass them through the knotted loop (FIG. 7(B)).
The bobbin 3 may be provided with an attachment device or a storage case for smoothly pulling out and rewinding the yarn. Also, a bobbin holder 11 for holding the bobbin 3 when the bobbin arm 8 is operated to pass through the knotted loop can be attached.
A bobbin hook 8a for hooking each bobbin 3 is arranged side by side at the tip of the bobbin arm 8. - 特許庁By lowering the bobbin arm 8 to grasp an individual bobbin 3 on the bobbin rack 6 and raising the bobbin arm 8 to pick up the bobbin 3, the individual bobbin 3 can be passed through the knotted loop.

After the bobbin 3 passes through the knotted loop, the net thread of the knotted loop hooked on the knotted guide hook 4 is released. When the knotted loop is released, the bobbin gauge 5 is lowered so as not to interfere with the drawing of the knotted loop (Fig. 7(C)).
The surplus yarn 12 of the released knot loop is wound back onto the bobbin 3 by the yarn winding device 7 and converges around the knot guide pin 19 (FIG. 8(A)). A temporary nodule is formed (FIG. 8(B)).

The yarn winding device 7 may be installed for each bobbin 3 or may control the unwinding operation of all the bobbins 3 by one unit. Also, even if the yarn winding device 7 is installed at a position where the bobbin arm 8 pulls up the bobbin 3, it is installed below the bobbin rack 6 so that when the bobbin 3 comes into contact with the yarn winding device 7, the yarn is wound. may work. By adjusting the yarn winding device 7, the mesh knot guide pins 19 are adjusted so that the yarns (the yarns 22 and 23) knotted on the mesh formwork plate 18 at the knot loop forming position maintain an appropriate tension without slack. A temporary knot (FIG. 8(B)) is formed around the knot 24 .

After the step of forming a temporary knotted network for forming a temporary knotted network for one stage is completed, knot preparation is performed for the next stage of the mesh.
The mesh form plate 18 for forming the next temporary nodule mesh on the mesh form 1 is moved to the nodule loop forming position. The bobbin gauge 5 is put back in place and the knot guide hook 4 is repositioned on the bobbin gauge 5 . Further, the bobbin arm 8 is operated to return each bobbin 3 to a predetermined position on the bobbin rack 6.例文帳に追加
As described above, the temporary knot knitted mesh comprising the knot preparation step, the knot loop forming step, and the temporary knotted mesh forming step is performed for each stage of the mesh, and this is repeated.

FIG. 11 shows an example of the mesh completion process.
The mesh adjusting device 9 is arranged at a position where the temporarily knotted portion of the mesh temporarily knotted by the movement of the mesh formwork 1 can be easily removed from the knot guide pin 19 . When the temporarily knotted mesh reaches the removal position, the mesh for one stage is removed from the mesh mold with the help of the mesh removal hook 9a. The temporary nodule mesh that has reached the mesh removing position is required to be removed while maintaining the formed temporary nodule mesh shape, and the temporary nodule mesh 28a can be removed without applying force or performing any special operation by the mesh removal hook 9a. It is desirable to have a structure in which the knot part can be smoothly removed from the knot guide pin 19 .
A temporary knot 27a before drawing is formed in the temporary knot mesh 28a before adjustment. For the temporary knotted mesh to be adjusted, for example, the knot stop 9b is inserted into the knot position on the side of the mesh removal hook 9a, the other knot is hooked to the knot draw and draw hook 9c, and the knot draw and draw hook 9c is pulled to stretch the net thread 12, Firmly squeeze the nodule 27b. At this time, the direction, distance, and strength of stretching the net yarn 12 are adjusted depending on the material of the net yarn 12, the mesh shape to be formed, and the like. By adjusting the distance between, for example, the knot stops 9b and the knot draw hooks 9c, it is possible to form a mesh with sides of the correct length.
The mesh 28b that has passed through the mesh adjuster 9 is incorporated into the mesh 29 and wound up by the mesh winding device 10. - 特許庁

The mesh completion process can be carried out in parallel with the series of temporary knot knitting processes, and can be processed for each stage of the mesh, or multiple stages of the mesh can be processed at the same time. When it is desired to knit a net fabric that combines a plurality of mesh shapes and knotting techniques, or to adjust the mesh shape of the entire net fabric, the mesh adjusting device 9 is provided with a function of adjusting the mesh patterns of a plurality of patterns. can be done.

As described above, according to the embodiments of the present invention, various and accurate sizes and mesh shapes can be obtained by knotting techniques and mesh shapes that could not be produced by conventional knotted net devices, such as regular hexagons, and combinations thereof. of knotted nets can be produced industrially.
In particular, by combining a closed knot formed by passing through the bobbin 3 with a knot loop formed by the net thread 12 pulled out from the bobbin 3 as shown in FIG. It is possible to produce a knotted mesh that is less prone to misalignment. Moreover, by using the mesh formwork 1, it is possible to form a mesh of an accurate size and shape.

Furthermore, according to the embodiment of the present invention, by forming knots by tightening the temporary knots in the mesh finishing process, the location where a strong force is applied to the mesh yarns 12 is limited to the mesh adjusting device 9 . A conventional knotted knitting net device is increased in size and speed, and a large load may be applied to the net yarn 12 and the knitting net device in the stitch feeding mechanism and the knitting mechanism. It is considered that by cutting the net, the load applied to the net yarns 12 and the knitting net device during knitting can be significantly reduced as compared with the conventional knotted netting device.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.
For example, the mesh adjusting device 9 may be composed of a pair of rollers arranged vertically. In this case, the pair of rollers pinches the temporary knotted mesh that has been detached from the knot guide pin 19 and feeds it to the netting winding device side, while drawing the temporary knotting using the winding tension of the netting winding device. You may make it complete a nodule.
