Description

The present invention, mutually placed set a pair of netting each mesh, about manufacturing network device of a double network that integrates.

  A fishing method (bottom stab) that catches seafood (sardines, yellowtails, Japanese flounder, flatfish, flatfish, cod, Thai, crabs, prawns, turban shells, etc.) caught in a net. A stabbed net used for a net, a floating stabbed net, etc.) is based on a configuration in which a single net is used, and as shown in Patent Documents 1 to 5, a double net is formed by laminating nets with different mesh sizes. There is also a stabbed net or triple stabbed net. These double stabbed nets or triple stabbed nets are configured to intermittently connect a supplementary net with a large mesh (meeting net) to the basic net (meat net, Patent Document 1). The fish catches seafood by enhancing its ability to catch seafood (hereinafter referred to as “fishing action”).

  In order to improve the fishing effect similar to the double stabbed net or the triple stabbed net, as shown in Patent Document 6, a fallen net having an appropriate length of play half eye attached to a single net. There is. Japanese Patent Laid-Open No. 2004-228561 clearly describes that a similar function or effect can be obtained for a sash net, that is, a net use amount can be saved and a damage prevention effect can be obtained.

  Double stabbed nets or triple stabbed nets have a higher catching action than basic single stabbed nets, but the nets that are mainly entangled with seafood are basic nets. From now on, the size of fish and shellfish that can be caught will depend on the mesh size of the basic mesh. Also, if the basic netting and the supplementary netting are entangled with seafood equivalently, the entanglement will be complicated, and it will be difficult to remove the caught seafood this time (hereinafter, netting). .

  From now on, in order to catch fish and shellfish reliably, the fish catching action that entangles the seafood in the net and the netting action that removes the entangled seafood from the net do not require contradictory action on the gill net. looks like. However, it is clear that stabbed nets that meet these conflicting requirements are most preferred. Therefore, both the catching action that can catch seafood of different sizes equally regardless of the size of the mesh and the release action that can easily remove the caught seafood from the net. In order to develop a double net suitable for a stabbed net, it was studied.

As a result of the examination, the developed one is composed of independent first and second nets, and forms a first net of the first net and a second net of the second net. This is a double net making apparatus in which yarns are alternately crossed and the first and second nets are entangled and integrated. That is, in the double net made by the net making apparatus of the present invention, the separate first and second nets are made separately and are not overlapped after the net making. Provided is a double net in a state where yarns forming each other's mesh are alternately crossed in advance in a stage.

The double net made by the net making apparatus of the present invention is, for example, a yarn that forms the first and second nets of the first net and the second net which are flat knotless nets. Can be made by adhering or welding the portions corresponding to the nodule portions to each other in a state where they are alternately hidden. However, when used as a fishing net, it is desirable that at least one net is a knot net from the viewpoint of the strength of the knot. That is, in the double mesh of the present invention, the first mesh is a knot network composed of the first warp and the first weft, one or both of the first warp and the first weft, and the second mesh. The yarns forming the second mesh are alternately crossed and the first mesh and the second mesh are entangled together, or the second mesh is a knot network composed of the second warp and the second weft, One or both of the second warp yarn and the second weft yarn and the yarn forming the first mesh of the first mesh are alternately crossed, and the first mesh and the second mesh are entangled and integrated. For the knot portion, a conventionally known rod or the like can be used.

More preferably, in the double net made by the net making apparatus of the present invention, the first net is composed of a knot net composed of the first warp and the first weft, and the second net is composed of the second warp and the second weft. A knot network, one or both of the first warp and the first weft and one or both of the first warp and the first weft are alternately crossed, and the first network and the second network are entangled It is the structure made into one. In this case, there is an advantage that a net making apparatus for making an existing nodule net can be used, and the double net of the present invention can be easily made without greatly changing the net making procedure.

In the double net made by the net making apparatus of the present invention, the yarn forming the first mesh of the first mesh and the yarn forming the second mesh of the second mesh are alternately integrated. Although there is a feature in the point, the first network and the second network are also characterized in that they are independent network. From here on, each network can set the type (material), thickness, or color of the thread to be used regardless of the network of the other party, and the present invention comprises the first network and the second network with the same specifications. In addition to the double network, a double network of the present invention comprising a first network and a second network with different specifications can also be configured. Specifically, (1) the first net is a double net that forms the first net with different types (different materials) of the yarn that forms the second net of the second net, and (2) the first net The mesh is a double mesh having a first mesh with yarns of a different thickness from the yarn forming the second mesh of the second mesh, or (3) the first mesh forms the second mesh of the second mesh For example, a double mesh that forms a first mesh with yarns of a different color from the yarn to be performed can be exemplified. Differences in the types or thicknesses of the yarns used for the first and second nettings lead to differences in strength and durability of the respective nettings. Moreover, the difference in the color of each thread | yarn used for a 1st netting and a 2nd netting brings about a difference in visibility.

  The type, thickness or color of the yarn is as follows: (a) the first mesh and the second mesh when the first mesh is a double mesh having the same size as the second mesh of the second mesh Since there is no master-slave in the network, it may be selected and combined as appropriate according to the purpose or demand of the double network. In contrast, (b) the first network is a double network having a first network larger than the second network of the second network, and (c) the first network is smaller than the second network of the second network. A double network having a first network is also conceivable. When both nets are knotted nets, the difference in the tensile force applied to each netting during the heat setting that is the finishing process brings about a difference in the shrinkage rate, and the first netting has a different mesh size. And a 2nd network can be comprised. In such a double net having different mesh sizes, there is a master-slave relationship due to the difference in the relative sizes of the first and second meshes. For example, the yarn used for the main mesh is thickened. It is possible to increase the strength or make the material special. In any case, although the double net of the present invention is entangled and integrated with each other, the first net and the second net are independent nets, so that the free thread can be selected. There is.

One of the features of the double net made by the net making apparatus of the present invention is that it can be made even by using an existing net making apparatus. Specifically, using a net making apparatus that knits the knit knit fabric by alternately knotting the warp yarns that meander between the adjacent weft yarns of the many weft yarns to be twisted with each of the adjacent weft yarns. The first weft and the second weft arranged in the same way, and the first warp that meanders between the first wefts while straddling the second weft is knotted with each first weft to form the first net that is a knot network The first warp of the first knitted fabric is knitted by knitting the second warp, which is a knot knitted fabric, by tying the second warp that meanders between the second wefts while straddling the first weft. Are alternately crossed with the second weft of the second netting, the second warp of the second netting is alternately crossed with the first weft of the first netting, and the first netting and the second netting are entangled. A double net making method is used to obtain a double net integrated.

Since the above-described double net-making method uses a network-making device for making a network having an existing knot, both the first network and the second network become knots. The net making method used in the net making apparatus of the present invention is such that the first weft of the first net straddles the first weft of the second net and the second weft of the second net is the first of the first net. 2 Stretch across the weft. In other words, the meandering is performed at intervals between adjacent wefts, whereas the present invention differs in that the wefts are meandered every other intervening intervening other wefts. In order to realize such meandering of the weft yarn, the reciprocating distance of the yarn swinging meandering the weft yarn may be doubled. That is, the first warp and the second warp are alternately inserted at equal intervals every other yarn, and the first and second wefts of the first and second wefts alternately arranged at equal intervals alternately. The yarn swing is reciprocated to the left and right at twice the arrangement interval of the second weft yarns, the first warp yarns of the first mesh fabric are alternately intersected with the second weft yarns of the second mesh fabric, and the second mesh fabric second A method is used in which the warp yarns are alternately crossed with the first weft yarns of the first netting. In order to double the reciprocation distance of the yarn swing, for example, the fulcrum of the rod for reciprocating the yarn swing by the swinging motion is adjusted, the undulation of the cam transmitting the swinging motion to the rod is doubled, etc. Can be considered.

  The cam undulation and the adjustment of the fulcrum of the rod can be easily applied to an existing net making apparatus, resulting in the following apparatus configuration. That is, the cam is rotated by the rotational power generated from the drive source, the rod is swung according to the cam undulation, and the yarn swinging through the warp is reciprocated within a predetermined reciprocating range by the rocking movement of the rod. In the net making apparatus having the yarn swinging means, the yarn swings are alternately arranged alternately, and through holes for inserting the first weft yarn and the second weft yarn are opened at equal intervals, and the first warp yarns are adjacent to each other. (A) Enlarging the cam and increasing the rocking width of the rod to meander between the first weft straddling two wefts and to meander between the second weft straddling the first weft adjacent to each other. To increase the swinging width of the rod by adjusting the fulcrum of the rod, or (2) adjusting the fulcrum of the rod. A networking device with a reciprocating range that is twice as long as the spacing between the insertion holes That.

The double net made by the net making apparatus of the present invention can provide a double stab net particularly suitable as a fishing net. Conventional double stab nets are obtained by simply laminating two separate nets, the sizes of the nets being fixed, and the nets of each net do not affect each other. On the other hand, since the double stab net by the double net of the present invention is in a state where the first net and the second net of the first net and the second net are intertwined, the relative position of each net Depending on the relationship, a mesh of varying size can be constructed. For example, if the sizes of the first mesh and the second mesh are equal, if the yarns constituting each mesh are overlapped, the maximum mesh is obtained, and if the yarns constituting each mesh are shifted halfway up or down or left and right The minimum mesh that the yarns constituting each mesh intersect can be configured. As a result, seafood is caught in large meshes, and the fish catching action that is captured by tightening the meshes while rampant, and the netting action that allows the fishes to be easily removed by spreading the nets after catching are combined. A barbed net can be provided.

Further, the double net made by the net making apparatus of the present invention is also a double net that can be used as a single unit with a separate network, and as described above, By stretching in a state where the yarns constituting each mesh of the second mesh are overlapped, the second mesh has a feature that can be used as a reinforced ground net. Here, it is conceivable that the ground net is composed of two yarns similar to the state where the yarns are overlapped. However, in the ground net composed of two yarns, the degree of freedom of two yarns per mesh. Is restricted, and it becomes only a ground net inferior in flexibility. On the other hand, the double network of the present invention is basically composed of separate first network and second network, so even if the yarns are overlapped in each network, the entire network is still mutually connected. Has a degree of freedom, and the degree of freedom as a ground net is not hindered. As described above, the present invention can provide a double net suitable not only as a fishing net but also as a ground net.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing an example in which a double stabbed net 3 is constituted by a double net according to the present invention, FIG. 2 is a partially enlarged perspective view in which a part of the double stabbed net 3 is enlarged, and FIG. FIG. 4 is a plan view corresponding to FIG. 1 showing a state in which the maximum mesh Smax is formed by overlapping the yarns 12, 13, 22, and 23 constituting the meshes 11 and 21, and FIG. Fig. 5 is a front view showing an example of the configuration, and Fig. 5 is a partial excerpt of the net making device 5 for explaining an example of realizing the double net making of the present invention using the existing net making device 5. In FIG. 1, the lower side of the intersecting yarns is subjected to hidden line processing (partially cut at the intersecting portion) with respect to the upper yarns so that the cross relationship between the illustrated upper yarns can be easily understood. In the following example, the same material and the same thickness are used for the first warp yarn 12, the first weft yarn 13, the second warp yarn 22 and the second weft yarn 23, and the sizes of the first mesh 11 and the second mesh 21 are set. An example of the same first network 1 and second network 2 is used.

  As shown in FIG. 1, the double net of the present invention appears to be composed of a single net in appearance, but actually the separate first net 1 and second net 2 are entangled. It is a configuration. Specifically, as shown in FIG. 2, for example, the first warp 12 constituting the first mesh 11 of the first mesh 1 passes the second weft 23 of the second mesh 21 of the second mesh 2 from above. The yarns 12 and 13 constituting the meshes 11 and 21 are straddled so that the first weft yarns 13 constituting the first mesh 11 are dived from below the second warp yarns 22 of the second mesh 21 of the second mesh 2. , 22, and 23 are alternately crossed so that the first network 1 and the second network 2 are entangled in mesh units (the first network in FIG. 2 is indicated by a bold line). However, since the first net 1 and the second net 2 are separate from each other, and the mutual threads 12, 13, 22, and 23 cross each other alternately, they are in a free state with each other. The overlapping degree of the mesh 11 and the second mesh 21 changes.

  Except for such entanglement in each mesh, each network 1, 2 is independent, and the structure of each network 1, 2 is not different from the existing network. Speaking of the double stabbed net 3 of this example, the first net 1 is composed of a first warp 12 and a first warp 13 connected by a first knot 14 such as a hook or the like to form a first net 11. Then, both sides are aligned with the first ear threads 25, 25, the first upper edge 16 is connected to the buoyant rope 31 and the first lower edge 17 is connected to the sword rope 32. In the second mesh 2, the second warp yarn 22 and the second weft yarn 23 are connected by a second knot portion 24 such as a cocoon or the like to form a second mesh 21, and both ears are provided with second ear yarns 25, 25 on both sides. The second upper edge 26 is connected to the floating line 31 and the second lower edge 27 is connected to the sediment line 32. In this example, the first network 11 and the second network 21 are the same because the existing network manufacturing device 5 described later is used to simultaneously network the first network 1 and the second network 2 entangled. The first knot portion 14 and the second knot portion 24 have the same specifications (for example, the same struts) in size (the length of the legs from the knot portions 14, 24 is the same). Here, if there is a difference in the tensile force applied to the meshes 1 and 2 during the heat setting that is the finishing process, the shrinkage rates of the meshes 1 and 2 are different, and the sizes of the meshes 11 and 21 are changed. Can be different.

  When the first network 1 and the second network 2 are configured as an integral double stabbed net 3, the floating cable and the sink cable can be separated, but the first and the second are commonly used as in this example. If the ear threads 15 and 15 and the second ear threads 25 and 25 are separately provided, the first net cloth 1 and the second net cloth 2 remain free from each other. As a result, the positional relationship between the first mesh 11 and the second mesh 21 changes, and the size of the mesh that actually catches seafood can be changed. For example, the state shown in FIG. 1 is that the first knot portion 14 or the second knot portion 24 of each of the meshes 11 and 21 of the first mesh 1 and the second mesh 2 is exactly in the middle of the meshes 11 and 21 of each other. The position, that is, the smallest mesh Smin (the portion indicated by the arrow A in FIG. 1) is formed (for convenience of illustration, the meshes 11 and 21 are drawn slightly shifted). Since the first mesh 1 and the second mesh 2 in this example are the same size, the minimum mesh Smin is 1/4 of the size of the first mesh 11 or the second mesh 21 (one side is 1/2). Therefore, the area is 1/4). On the other hand, when the yarns 12, 13, 22, and 23 constituting the meshes 11 and 21 overlap each other, as shown in FIG. 3, the maximum mesh Smax (approximately equal to the first mesh 11 or the second mesh 21). 3 can be formed. Usually, with a stabbed net, the size of the net is determined according to the type and size of the fish and shellfish to be caught, and the size of the net is fixed. For this reason, a large number of gill nets are required for various seafood. Since the double stab net 3 by the double net of the present invention can change the size of the nets Smax and Smin that actually catch the seafood, even if the size of the seafood to be caught changes somewhat. The same fishing effect can be demonstrated. Thus, the double net of the present invention provides a double stab net 3 with a wide range of fishing targets.

  In addition, the four sides of the first and second nets 1 and 2 illustrated above, that is, the ear threads 15 and 25, the upper edges 16 and 26, and the lower edges 17 and 27 are all integrated with the edge cloth 41. 4 and stretched between the poles 42 and 42 as shown in FIG. 4, the ground net 4 in which the first and second nets 1 and 2 entangled with each other in one plane can be configured. At this time, if the first network 1 and the second network 2 are in a relationship that forms the minimum network Smin (see FIG. 1), the first network 11 and the second network 21 of each network 1, 2 are connected. Although it is large, the ground net 4 having a small mesh as a whole can be obtained. On the contrary, if the maximum mesh Smax (see FIG. 3) is formed, the yarns 12, 13, 22, 23 of the first mesh 1 and the second mesh 2 are overlapped and can be reinforced with each other. Here, the feature of the terrestrial network 4 using the double network of the present invention is that it is composed of a first network 1 and a second network 2 that are entangled with each other but independent of each other. For this reason, even when the obstacle collides, each of the meshes 1 and 2 can be deformed to the maximum, so that the obstacles can be easily received and the meshes 1 and 2 reinforce each other. It is hard to be torn by a collision. Thus, unlike the conventional case, the double network of the present invention provides a ground net 4 that is flexible but difficult to break.

  The 1st network 1 and the 2nd network 2 which comprise the double network of this example are the structures which have the 1st knot part 14 and the 2nd knot part 24, respectively. A double network composed of the first network 1 and the second network 2 having the knot portions 14 and 24 can be easily manufactured using the existing network device 5 as shown in FIG. Specifically, every other first warp thread 12 and second warp thread 22 are arranged side by side through a plurality of winding rods 51 and thread swings 53 extending along triangular teeth 52 and inserted into insertion holes 54 respectively. Then, by making meander every other warp straddling the warp yarns 12, 22, yarns constituting the first mesh 11 and the second mesh 21, respectively, specifically, the first warp yarn 12 and the second weft yarn 23, And the 1st weft 13 and the 2nd warp 22 cross | intersect mutually, and become the double net | network where the 1st net 1 and the 2nd net 2 were entangled. In the double netting network of the present invention using the existing netting device 5, the sizes of the nets 11 and 21 of the first net 1 and the second net 2 are equal, and the nets 11 and 21 are the same. The nodules 14 and 24 are of the same type, for example, the same saddle. However, since the networking procedure is the same as the conventional one, there is an advantage that the double network of the present invention can be easily networked without causing an increase in the networking cost.

  Since the meandering of the first warp yarn 12 and the second warp yarn 22 follows the reciprocating motion of the yarn swing 53, it can be seen that the reciprocating range of the yarn swing 53 may be doubled as compared with the conventional method. Many conventional netting devices 5 rotate the cam 56 by the rotational power generated from the drive source 55, swing the rod 57 according to the undulation of the cam 56, and swing the yarn by the swinging motion of the rod 57. Yarn swinging means 58 is configured to reciprocate 53 within a predetermined reciprocating range. From this point, for example, if the undulation 561 of the cam 56 is doubled or the oscillating width of the rod 57 is increased by adjusting the fulcrum 571 of the rod 57, the predetermined reciprocating range of the yarn swing 53 can be easily doubled. Such remodeling of the existing net making apparatus 5 does not involve any significant apparatus remodeling, so that the equipment cost required for making the double net of the present invention can be kept low. In addition, the double net making using the existing net making device 5 thus modified is the same as the conventional net making procedure, so the net making cost does not change. The cost required for net production can be minimized.
