Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sinker line and a float line that float in water or in the sea, and to a fishing net using these.
[0002]
[Prior art]
In general, it is known to use a scorpion and a float as a fishing net such as a winding net and a trawl net, and a stab net, a stationary net, an aquaculture net, and the like are also known. Therefore, the conventional scorpion rope used in the above-mentioned various fishing nets has a weight made of lead or the like fixed to a rope at an appropriate interval. On the other hand, the conventional levator rope has a buoyant body called a float made of synthetic resin foam or the like fixed to a rope at an appropriate interval.
[0003]
In addition, in the case where a winding net or trawl net is provided using the above-described scorpion rope and buoyant rope, the sinking force of the scorpion rope and the buoyancy of the buoyant rope are made uneven and are given to a continuous rope. The size and number of weights or floats were adjusted so that the settling force or buoyancy changed partially. As described above, the reason for changing the sinking force or buoyancy in the scorpion and floats is to change the fishing net mechanism according to the conditions of the fishing ground and the type of seafood to be captured.
[0004]
In this case, if the tow line that is continuous with the fishing net is towed by a net ship, such as a seine net or trawl net, the entire scorpion line will sink to the vicinity of the seabed, and the entire buoyant line will float near the water surface. In addition, the sinker rope is made heavy by the weight in the vicinity of the net ship so that the sinking force is strengthened so that it does not easily float by towing. In addition, a bag-shaped net portion called a “bag net” (or “fish catch”) is formed at the center of the fishing net such as the winding net or trawl net. Even in the area, a sinking force is applied so that the sash rope can stay near the seabed. And since the tow by a net ship becomes easy as a whole, the size of the weight is adjusted so as to limit the settling force. In this case, the limit of the settling force is adjusted by the number of weights, and this weight connects a bag-shaped weight body enclosing lead or the like to a predetermined portion of the scorpion rope.
[0005]
On the other hand, in the float, the strength of the buoyancy is adjusted in accordance with the arrangement of the weight in the above-described scorpion rope, A powerful buoyancy was imparted. This is to expand the opening of the fishing net as described above in the range from near the sea floor to near the water surface. When a large float is added to the float, it is adjusted by increasing the number of floats. It was a thing.
[0006]
[Problems to be solved by the invention]
However, each of the above-described scorpion and floats has a structure in which a weight or float is fixed to the surface of each rope, and these weights or floats protrude significantly on the surface of the scorpion or float. It was. Accordingly, since the surfaces of both ropes have a distorted uneven shape, when winding the winding net or trawl net, not only the drum part of the winding winch may not be wound, but the weight or float When entangled in a net, the net may be damaged, or the float or the rope main body may be damaged. In addition, the connection tool (usually the string material) for connecting the weight or float may be worn out, and the weight or float may be detached from the scorpion or float. Especially when the weight is detached, As a result, the lead that is normally used remains on the seabed, causing a problem of adversely affecting fish. After the capture operation, it is necessary to check the presence or absence of the damage, and when the damage is discovered, a repair operation must be performed.
[0007]
In addition, since the conventional scorpion rope or buoyant rope adjusts the settling force or buoyancy according to the number of weights or floats installed, the sinking between the place where the weight or float is provided and the place where it is not provided. Force or buoyancy is extremely different, and the scorpion or floats where the weights or floats are provided are subject to tension in the vertical direction in the water, but are loosened in tensions where no weights or floats are provided. The entire rope formed a so-called arch shape. This is conspicuous in the sash rope, and the sash stakes where the weight is not provided has a slight buoyancy, and this part floats, so the part provided with the weight sinks to the sea floor, The part surfaced and a large arch was formed. Therefore, the seafood to be captured can pass through the arch-shaped hole, resulting in a decrease in the amount captured.
[0008]
The present invention has been made in view of the above-mentioned points. The object of the present invention is to eliminate the need to connect a weight or float to the sacrificial rope or buoyant rope, and to partially reduce the settling force or buoyancy of the braided rope itself. It is to provide a continuous sinker line or float line, and to provide a fishing net using these.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, an embodiment of the present invention relating to a braided sinker line will be described. As shown in FIG. 1, the sinker line 1 of the present embodiment is a braided rope called a sash rope, 12... 17 are braided into a continuous braided shape. In this sinker line 1, a plurality of the same kind of settling members 2 are built in continuously in the longitudinal direction, and the surface in a state where a predetermined number of settling members 2 are bundled with braid cords 11, 12,... Braided.
[0019]
Here, as shown in FIG. 2 (a), the settling member 2 has a lead settling body 22 fixed to a continuous thread-like member 21 with an appropriate interval. 21 and the gap between the sediments 22 constitute a flexible state similar to the string as a whole. That is, although the sediment 22 itself is not flexible, the gap portion between the adjacent sediments 22 can be deformed by the flexibility of the thread-like member 21, and the deformation is allowed within a range where the adjacent sediment 22 does not contact. It has been done.
[0020]
Moreover, it is possible to concentrate the settling force of each settling body 22 by changing the number of the settling members 2. Accordingly, as shown in FIG. 2 (b), the portion A in which many sedimentation members 2 are bundled has a large diameter, while the diameters of the portions B and C are gradually reduced as the number is decreased. The diameter of the entire rope braided also changes gradually according to the diameters of these portions A, B, and C.
[0021]
Therefore, when the sediment 22 is made of lead and the specific gravity of lead is 11.34 g / cm @ 3, a weight of about 300 g can be obtained with 26.455 cm @ 3 of lead. If the cylindrical sediment 22 having a radius of 3 mm is provided, the length is about 935.65 mm, and if this is divided into 64 pieces, the length per piece may be about 14.62 mm. In addition, if the gap between the sediments 22 is 1 mm, the sedimentation member 2 having about 300 g per 1 m (1000 mm) can be provided.
[0022]
When the sedimentation member 2 configured as described above is used, for example, by bundling the 11 sedimentation members 2 of about 300 g / m, a weight of 3300 g / m can be obtained, and 17 bundles are bundled. Thus, 5100 g / m can be obtained, and further 20 bundles can obtain respective weights of 6000 g / m. If the bundles of the settling members 2 are braided with the braid cords 11, 12,... 17, an error occurs due to the weight of the braid cords, but the 11 bundles are approximately 4 kg / m, 17 bundles. Thus, a sinker line of 6 kg / m can be obtained, and a bundle of 20 can provide a sinker line of 7 kg / m.
[0023]
In this case, as described above, the outer diameter of each part of the sinker line 1 to be braided is different, but the outer diameter is 16 mm in the part where the sinking member 2 is not built in and the outer part C in which the 11 sinking members 2 are bundled. The diameter B is 30 mm, the portion B where the 17 settling members 2 are bundled has an outer diameter of 36 mm, and the portion A where the 20 settling members 2 are bundled has an outside diameter of 38 mm. In addition, the change to each part A-C as mentioned above does not generate | occur | produce an extreme outer diameter change by increasing / decreasing a number gradually, Thereby, it can be made to wind smoothly on the drum of a winding winch. Is possible.
[0024]
Next, a second embodiment will be described. In this embodiment, as shown in FIG. 3A, in addition to the sedimentation member 2 built in the sinker line 1 or in place of the sedimentation member 2, a non-sedimentation member 3 is built. . The non-sedimenting member 3 is made of a polymer compound such as polyethylene and is excellent in rigidity with respect to the longitudinal direction of the sinker line 1. On the other hand, although the specific gravity is smaller than seawater or fresh water, buoyancy can be obtained. It is not a thing. If there is a part of the sinker line 1 that does not require any settling force or buoyancy, a braided rope that contains only the non-settling member 3 is formed at that place. Thus, by providing the non-sedimenting member 3 continuously inside the sinker line 1 regardless of the presence or absence of the sedimenting member 2, the sinker is in the stage before braiding with the braid cords 11, 12,. The original shape of line 1 can be preconfigured. That is, by connecting the thread-like member 21 of the sedimentation member 2 with the non-sedimentation member 3 as a base material, the braided cords 11, 12,... A desired sinker line 1 can be configured.
[0025]
As a third embodiment, as shown in FIG. 3B, the sinker line 1 is used as a core material, and braided cords made of different materials are braided around the sinker line 1. It is. According to the said structure, the sinker line 1 of 1st or 2nd embodiment can be incorporated in the center of the sinker line 101 comprised with the braid cord of the said material. If comprised in this way, according to the use of the sinker line 101, what has abrasion resistance etc. can be comprised.
[0026]
In the third embodiment, when the sinker line 1 in the first embodiment is used as a core material, the outer diameter of the sinker line 101 of the present embodiment is used if the above-described lead sediment 22 is used. Is 32 mm in the portion where the settling member 2 is not built in, 40 mm in the portion where 11 settling members 2 are provided, 45 mm in the portion where 17 settling members 2 are similarly provided, and in the portion where 20 settling members 2 are provided. 49 mm. In addition, the braided cord that is braided in any of the first to third embodiments does not impart sinking force or buoyancy to the sinker line 1, 101, and thus affects the function as a sinker line in water. Does not give.
[0027]
Next, an embodiment according to the braided float line will be described. The float line of the present embodiment is a braided rope also called a float rope, and instead of the sediment 22 used in each of the embodiments in the sinker lines 1 and 101, a buoyancy body made of a synthetic resin foam is provided, This buoyancy body constitutes a buoyancy member. If comprised in this way, the float line which consists of the structure similar to the said sinker lines 1 and 101 can be provided, and the buoyancy member comprised similarly to the said sedimentation member 2 can be incorporated in the inside. It is. That is, a buoyancy member having a flexible structure is formed by fixing a buoyancy body to the thread-like member 21 used for the settling member 2, and the specific gravity is partially adjusted by changing the number of the buoyancy members. .
[0028]
As described above, the built-in buoyancy member also in this embodiment is formed by fixing a plurality of buoyancy bodies to the thread-like member. Like the sinking body 22 of the sinker line 1, the buoyancy member has a radius of 3 mm and a length of 935. .65 mm synthetic resin foam is divided into 64 pieces and each gap is set to 1 mm, the same effect as a float having a volume equivalent to about 26.454 cm 3 per buoyancy member can be obtained. 11 bundles are equivalent to the case where a float corresponding to about 290.994 cm 3 is provided, and the outer diameter at this time is about 30 mm.
[0029]
In the float line, as in the case of the sinker line, it is possible to constitute the second and third embodiments in addition to the first embodiment. That is, when braiding with a braided cord, a non-buoyant member continuous in the longitudinal direction can be built in, and this non-buoyant member can be composed of a polymer compound such as polyethylene as well. Furthermore, it is also possible to configure the float line according to the third embodiment in which the float line according to the first or second embodiment is used as a core material and the periphery thereof is braided with braided cords.
[0030]
In addition, about the said sedimentation member 2 and a buoyancy member, both the said sedimentation body 22 and a buoyancy body can be shape | molded in a substantially cylindrical shape, and this can be fixed, penetrating with a thread-like member, In some cases, it may be sandwiched by mechanical means, or may be bonded or welded by chemical means. Any method can be used as long as it can be fixed with an appropriate interval.
[0031]
Since the sinker line and the float line of the present embodiment are configured as described above, the lead sediment 22 and the buoyant body of the synthetic resin foam are both incorporated in the sinker line 1, 101 or the float line. Thus, even if friction or the like acts on the surface of these lines, the sediment 22 or the buoyancy body is not easily detached. Thereby, in particular, the sediment 22 does not remain in the sea, and it is possible to prevent the seafood from being adversely affected. In addition, the surface of the braided rope forming both the lines has a difference in the outer diameter, but the weight is not extremely protruded from the braided rope. Even when a lifting winch is used, both the above lines can be wound around a drum. Furthermore, among the continuous sinker lines 1, 101 or the float line, it can be easily determined that the large-diameter portion is configured to have a larger settling force or buoyancy than the other portions. Therefore, it can be used without misidentifying the state of settling force or buoyancy when the rope is used.
[0032]
Next, a winding net or trawl net using this embodiment will be described. First, the configuration of a general winding net or trawl will be described. As shown in FIG. 4, two tow ropes 4 and 5 to be towed by a towed ship are arranged symmetrically, and these tow ropes 4 , 5 are connected to the cocoon ropes 4 and 5, respectively. A fishing net such as a winding net or a trawl net is constructed by a net member 8 being stretched between the sagittal rope 6 and the floating float 7. Here, the sash rope 6 and the float rope 7 are each constituted by one continuous piece, and a bag called a “bag net” or “fish catch” (hereinafter referred to as a bag net) 9 is provided at substantially the center of the net member 8. A portion formed in a shape is provided, and the slat rope 6 and the float rope 7 at a position corresponding to the opening of the bag net 9 can be widened greatly. In addition, the weight 61 is fixed to the sash rope 6 at an appropriate interval, and the float 71 is similarly fixed to the floating rope 7 at an appropriate interval. In the weight 61, several weights are concentrated in one place so that the individual weights are 5.25 kg to 6.0 kg, and the concentrated weights are appropriately fixed. One float 71 is composed of a single lump of synthetic resin foam.
[0033]
The winding net or trawl net having the above-described configuration is towed by the so-called net boat at the tip of the leopard ropes 4 and 5, so that the sagote rope 6 and the float float 7 connected to the leash ropes 4 and 5 are located near the sea surface. Or it moves around the sea bottom, respectively, and guides the seafood to be captured to the bag net 9. Thereafter, one dredger 5 is moved by the so-called dredger to the other so-called main ship, and the seafood captured by the bag net 9 is rolled up by sequentially winding from both the leash 4 and 5 on this single main ship. It can be done. Here, the hoisting by a single parent ship is operated by a hoisting winch, and the leopard ropes 4 and 5, the scorpion rope 6 and the float rope 7 are wound around the drums constituting the winch, respectively. In the purse seine and the bottom trawl net, only the scorpion rope 6 is used, and the target fish and shellfish are captured while moving the scorpion rope 6 that sinks near the seabed.
[0034]
Therefore, in the embodiment according to the fishing net of the present invention, the sinker line D as shown in FIG. 5 is used as the sacrificial rope 6, and this sinker line D is obtained by partially changing the settling force. is there. That is, as shown in the drawing, near the both ends of the sinker line D, there are provided non-sedimentation portions 10 and 50 in which no sedimentation member is incorporated. Since the non-sedimentation parts 10 and 50 are used as parts corresponding to the above-described ropes 4 and 5, they do not require a sedimentation force, and are thus configured to be the lightest. Then, following one (left side in the figure) of the non-sedimentation portion 10, an intermediate sedimentation portion 20 containing an intermediate (17 in the above example) sedimentation member is provided. Since the intermediate sedimentation portion 20 has an outer diameter larger than that of the non-sedimentation portion 10, the boundary portion between both has a taper and is braided so that the diameter gradually increases.
[0035]
Further, a light sedimentation portion 30 containing a small amount (11 in the above example) of sedimentation members is provided following the intermediate sedimentation portion 20. This lightly settled portion 30 is a portion that is disposed over most of the above-described fishing net, and is also disposed at the opening of the bag net 9. Since the lightly settled portion 30 has an outer diameter smaller than that of the intermediately settled portion 20, the lightly settled portion 30 is braided so as to have a taper at the boundary portion between the two.
[0036]
Further, between the light sedimentation portion 30 and the non-sedimentation portion 50 at the other end (right end in the figure), a heavy sedimentation portion 40 containing a large amount (20 in the above example) sedimentation members is provided. . The heavy sedimentation portion 40 is provided after the tip 50 on the side that moves frequently. When moving the non-sedimentation portion 50 used as a leash, other heavy sedimentation portions 40 are used so as not to easily float from the vicinity of the seabed. The specific gravity is higher than this part. That is, the non-sedimentation part 50 continuing to the severe sedimentation part 40 is towed by the dredger.
[0037]
In the sash class using the sinker line D, the length distribution of the non-sedimentation parts 10 and 50 and the sedimentation parts 20, 30, and 40 is as follows. The non-sedimentation parts 10 and 50 are 2 m, the medium sedimentation part 20 is 5 m, the mild sedimentation part 30 is 85 m, and the heavy sedimentation part 40 is 10 m. If comprised in this way, the heavy weight sinking parts 20 and 40 will be arrange | positioned in the part close | similar to a main ship and a dredger, and the rise of a scorpion rope can be prevented by the movement of a main ship and a dredger. In addition, the sash rope has different outer diameters at the same time as the weight is changed. However, the outer diameter changes extremely because the outer surface is braided in response to these changes in outer diameter. is not. Therefore, when hoisting and hoarding are hoisted by a hoisting winch on the ship, there is no possibility that the change in the outer diameter interferes with each hoisting process.
[0038]
On the other hand, if the float line used for the float 7 is described, as shown in FIG. 6, the float line E is provided with the buoyancy changed as in the case where the sinking force of the sinker line D is changed. ing. Here, in the fishing net of the present embodiment, the buoyancy of the float line E is adjusted and distributed corresponding to the sinking force of the sinker line D described above. That is, in the vicinity of both ends, non-buoyant portions 110 and 150 having no built-in buoyancy member are provided, followed by one (left side in the figure) non-buoyant portion 110, followed by medium buoyancy portion 120, light buoyancy portion 130, The heavy buoyancy portions 140 are successively formed. The lengths of the non-buoyancy portions 110 and 150 at both ends are 2 m, the medium buoyancy portion 120 is 5 m, the light buoyancy portion 130 is 85 m, and the heavy buoyancy portion 140. Is 10 m, and a light buoyancy portion 130 is provided at a portion facing the light sedimentation portion 30 constituting most of the above sinker line D, while a portion facing the portion 40 having a large sedimentation force is provided at A portion 140 having a large buoyancy is provided.
[0039]
Since the structure is as described above, the fishing net in which the net member 8 is arranged between the sacrificial rope 6 using the sinker line D and the float rope 7 using the float line E, the sacrificial rope 6 sinks near the seabed. Even if the severely settled portion 40 sinks strongly, the relationship is balanced by the severely buoyant portion 140 of the leopard rope 7, and the net member 8 can be made to be in a state suitable for fishing by expanding up and down. .
[0040]
The embodiment of the present invention is as described above, but various modes can be taken without departing from the spirit of the present invention. For example, the sediment 22 is shown only for lead. However, the sediment 22 may be composed of other high specific gravity materials, and the buoyancy body is limited to a synthetic resin foam. Instead, materials that are widely used as floats can be used. Moreover, about embodiment concerning a fishing net, although the winding net | network or trawl net | network which uses the sinker rope 6 and the floater rope 7 which use a sinker line and a float line simultaneously were demonstrated as a representative example, either one line is used as a scorpion rope. 6 or other nets used as the float 7 can be configured, and in this case, the distribution of the weight is naturally different depending on the type of the desired net. Furthermore, the sinker line or float line can be used for purposes other than fishing nets, and an extreme example is the use of the float line as a course rope for a pool. In this case, it is possible to configure the entire course rope with a uniform diameter, but in order to obtain a form similar to an existing course rope, the large diameter portion and the small diameter portion can be provided intermittently.
[0041]
【The invention's effect】
As described above, according to the braided sinker line and the braided float line of the present invention, since the buoyant body or the sediment can be built in the braided rope, the sediment is formed so as to protrude from the surfaces of the two lines. Or it is not necessary to stick a buoyancy body. In addition, when using as a scorpion or float that is used for fishing nets, the outer diameter is different, but it does not protrude greatly, so it can be wound with a hoisting winch. is there.
[0042]
Furthermore, since the sinker line or float line has a plurality of settling members or buoyancy members built in and the weight can be changed only by increasing or decreasing the number of settling members or buoyancy members, Alternatively, it is easy to partially change the buoyancy. Further, according to the configuration in which the non-sediment member is provided inside the sinker line or the configuration in which the non-buoyancy member is provided inside the float line, the settling member or the buoyancy member is attached to the non-sediment member or Since it becomes possible to make it continue to a non-buoyancy member, the braiding of each line can be performed easily. Moreover, since both the lines are braided with braided cords, it is possible to incorporate a sedimentation member or a buoyancy member.
[0043]
On the other hand, according to the present invention relating to a fishing net, when a hoisting operation is performed by a hoisting winch, the weight or float is not caught by the drum portion or the like of the hoisting winch. The situation of withdrawal can be resolved. As described above, since the weights or floats do not exist so as to protrude, these weights or floats do not get entangled in the net when throwing or lifting nets, causing damage to the nets, etc. There is no need for network repairs. Furthermore, since the specific gravity of the braided rope itself can be adjusted, the rope can be entirely settled or levitated by giving a settling force or buoyancy to the entire rope, and a settling force or buoyancy is partially applied. By changing, it is possible to achieve the same settling and buoyancy state as a conventional fishing net.
