(Points of interest)
Japan is surrounded by the sea on all sides and has a long north-south territory. The weather conditions vary greatly depending on the season and region, the rainy season front appears in the early summer, which is the agricultural season, and the hot and humid days appear in summer. In addition to being sometimes hit by typhoons and torrential rains, it is characterized by severe daily weather changes, and crops must be selected according to the local weather conditions. In addition, there is a characteristic that there are relatively many farmers who are engaged in institutional farming using glass greenhouses and plastic houses that maintain appropriate temperature of crops for easy cultivation efficiency and easy countermeasures against wind and rain and pests.

    Such facility-type agriculture, especially solar-powered cultivation, has the advantage of reducing construction costs and operating costs by using glass or plastic film as a covering material, thereby reducing cultivation costs. Because it has the property of requiring fine grain management such as ensuring air permeability and shielding light according to seasonal changes and being easily affected by the outside world by opening the covering material accompanying such management work, insect control, The use of various agricultural nets according to various purposes such as bird protection, beast protection, wind protection, fence protection, light shielding, and heat insulation has become necessary and indispensable for producing high quality crops.

    However, as shown in the perspective view of the conventional agricultural net stuck to the pipe house of FIG. When it is pinched and fixed using individual packers (clasps) T, T, etc., it will be damaged by loosening and wear gradually under the influence of strong winds, and pests, birds, monkeys, etc. will enter through the gaps. There is a risk of forgiveness, and it is relatively easy to cut by the strong contact when it is sandwiched between the packers (clasps) T, T,... The nets that have been damaged cannot be easily repaired, and will require a great amount of repair costs and repair man-hours. Therefore, the entire farm net 1 must be replaced in the early stages. It was.

    Furthermore, as shown in FIG. 4, the agricultural net 1 mounted so as to hang down on the peripheral wall of the pipe house H, when rolled up for lighting, humidity management, ventilation, etc., loosened parts after tensioning However, it is difficult to maintain a horizontal posture, and it becomes impossible to form a uniform opening in the ridge direction of the pipe house H, making it difficult to uniformly manage the environment inside the house H. It was what had.

(Conventional technology)
Among them, as a possible solution to this problem, as in the “net-like” invention disclosed in Japanese Patent Application Laid-Open No. 2003-89942, propylene and α- A propylene copolymer layer composed of an olefin, a three-layer flat yarn comprising a polypropylene layer in the middle core layer is used as one of the weft yarns, and the sheath component is propylene and an α-olefin. A sheath-core type composite monofilament yarn having a propylene copolymer consisting of polypropylene and a core component is woven as the other of the warp and weft. Preventing misalignment and unraveling of the edge, obtaining sufficient strength and withstanding repeated exhibition books, and disclosed in Japanese Patent Application Laid-Open No. 2001-251976 “netting” invention The warp and weft are knitted, and at least one of the warp and weft is a net using cross-linked continuous yarns in which a plurality of monofilaments are arranged side by side, and is durable against misalignment. A non-woven fabric in which long fibers filaments of synthetic resin are deposited and bonded in a high density and in a non-directional direction are slit into narrow widths, which is capable of providing a net, and disclosed in Japanese Patent Application Laid-Open No. 10-327684 "Shading Net" invention Durability and weather resistance to withstand long-term outdoor use by heat-sealing tape-like yarns at least on one side of a net fabric obtained by weaving or crossing flat yarns or filaments of synthetic resin. Or a net-shaped fiber molded body and a method for producing the same disclosed in Japanese Patent Application Laid-Open No. 8-23796. , Laminate a reinforcing material at the end, heat-bond the intersection of the net and the net and the reinforcing material by heat treatment, or increase the weave density of the end, and further fix the annular member to the reinforcing part There are some things that prevent misalignment and have reinforced ends.

    However, the former “net-like” is one in which a three-layer flat yarn is used for either one of the warp yarns and a sheath-core type composite monofilament yarn is used for either one of the warp yarns. Compared to a net formed by binding traditional warp and weft yarns, the wall thickness is easy to enlarge, and the area of mesh opening (mesh) is narrowed, so high air permeability cannot be secured. The weight per unit area increases and the handling workability is deteriorated, and the above-mentioned “netting” also has at least one of the warp and weft with a plurality of monofilaments. It is intended to provide a strong net that can prevent misalignment by using continuous yarns with cross-sectional shapes arranged side by side, but because the continuous yarn is used over almost the entire surface of the mesh, the conventional type Small compared to the mesh It was those that leave the disadvantage becomes eye if set.

Similarly, the “light-shielding net” is obtained by heat-sealing a non-woven tape-like thread at least on one side of the net base fabric with a relatively narrow interval. It is a desirable structure for a shading net because it blocks the daylighting, but it cannot but be said that it is almost impossible to use as a birdproof net or an animal net that emphasizes daylighting and breathability. In addition, the structure of heat-welding non-woven tape-like yarns that are different from the material of the net base fabric has the disadvantage of increasing raw material costs and complicating the manufacturing process. Furthermore, the latter “net-like fiber molded body and its manufacturing method” is also made by laminating a reinforcing material on the end of the net and thermally fusing it, or increasing the weave density at the end of the net. Increase strength Although the things, the structure in which the reinforcement only at the end of the net, had a disadvantage that it is not possible to reliably prevent the misalignment or looseness and the like of the near net center in Zhang after casting.

(Awareness of problems)
As mentioned above, the previously proposed “net-like”, “netting” and “light-shielding net” are either warp or warp so as to ensure sufficient strength and prevent misalignment. One of the width dimensions has been expanded to increase strength, and it can be said that it has an effective structure as a light-shielding net. In addition, the “net-shaped fiber molded body and its manufacturing method” are said to have increased strength by reinforcing the end of the net, but in the vicinity of the center of the net. Insufficient strength was provided, and it was not possible to reliably prevent slack and misalignment after tensioning.

(Object of invention)
Therefore, the present invention does not cause a new problem, is almost as light as a conventional product, has excellent handling workability at a high place, and has high dimensional maintenance and shape maintenance performance. Judging whether it is possible to develop a new industrial net that reliably prevents later slack, misalignment, and deformation, and also has excellent durability against pinching with fasteners, it can be done quickly. As a result of starting development and research, and repeating trial and error over many years and many trial productions and experiments, we have finally succeeded in realizing an agricultural net with a new structure. The configuration of the present invention will be described in detail together with an embodiment representative of the present invention shown in the drawings.

(Structure of the invention)
As can be clearly understood from the embodiments representing the present invention shown in the drawings, the agricultural net of the present invention basically comprises the following configuration.
That is, for a plurality of warps arranged in parallel for each predetermined pitch dimension, a plurality of weft cords are crossed in a graticule shape so as to have a predetermined mesh size, and a square mesh is formed as a combined shape. 1 or two or more warps in parallel with each other within a predetermined plurality of adjacent warp pitch dimensions each having a predetermined interval between both ends of each weft cord. In addition to forming a section, it is formed by inserting a tying rope that is set at a length that exceeds the overall length of the warp string along at least the distance between the weft straps in the vicinity of the inner edge of the reinforcement band disposed at both ends of each weft strap. This is an agricultural net with the intended structure as its gist.

    This can be expressed in a different way. For multiple warps arranged in parallel for each predetermined pitch dimension, multiple weft cords are crossed into a graticule so as to have a predetermined scale size. As a mesh having a square mesh, and one or two or more warps are placed in each of a predetermined plurality of adjacent warp pitch dimensions at predetermined intervals between the ends of each weft cord. In addition to forming a reinforcement band through the parallel shape, at least the length of the tie strap set to a length exceeding the total length of the warp string along the weft string interval near the inner edge of the reinforcement band part arranged at both ends of each weft string When the tying rope is inserted and each warp string is substantially horizontal and each weft string is stretched in the vertical direction, each reinforcement band reinforces the mesh surface and the entire mesh surface An agricultural net designed to prevent the occurrence of slack and bias.

    And if it shows as a thing of a more concrete structure, it will be arranged in parallel for every predetermined pitch dimension, and each will be arranged with a plurality of warp strings which twisted a plurality of strands, and a plurality of each Between the plurality of weft strings formed by bundling the strands of the book and the strands of the former plurality of warp strings, each of the latter weft strings has a predetermined size. A mesh-like mesh body that is passed through the graticules to form a square mesh, and within a predetermined plurality of adjacent warp pitch dimensions at predetermined intervals between the weft cord ends. In each of the above, one or two or more warps are passed in parallel to form a reinforcing band portion, and at least according to the weft string interval near the inner edge of the reinforcing band portion arranged at both ends of each weft strap The tie ropes that are set to a length that exceeds the total length of the warp string are inserted into the strands of each weft string in a cross shape. It can be said that the agricultural net consisting formed.

    More specifically, each of the predetermined pitches 1 to 50, which are arranged in parallel with each other, is a plurality of warp strings each of which is twisted with a plurality of synthetic resin strands, and a plurality of each of them. Between the strands of the wefts made by bundling the strands of the yarn and the strands of the former plurality of warps, each of the latter wefts has a mesh size of 1 to 50 · In the arrangement as described above, it is a mesh net-like mesh body that is passed in a graticule shape to form a square mesh, and each weft cord has a width of about 80. A reinforcing band portion is formed by passing one or two or more warps parallel to each other within 100 to 2 adjacent warp pitches within a range of The tie ropes that are set to a length that exceeds the overall length of the warp cords along the distance between the weft cords near the inner edge of the belt part, It is possible that sequentially inserted through and becomes one with the agricultural net in cross shape.

    In other words, a plurality of warps arranged in parallel for each predetermined pitch dimension, each of which is a twist of a plurality of strands, and the plurality of warps Each part of the yarn is branched from the middle of the length direction for each predetermined size and twisted together with the adjacent warp strands to form a binding shape. A reticular mesh-like mesh body in which a plurality of weft cords made of bundle-like strands intersecting at right angles is formed, and a square mesh mesh intersecting in a graticule shape is formed between the ends of each weft cord A reinforcing band is formed by passing one or two or more warps parallel to each other within a predetermined plurality of adjacent warp pitch dimensions at predetermined intervals, and is arranged at least at both ends of each weft cord. For each weft strap, connect the tie rope that is set to a length that exceeds the total length of the warp straps along the distance between the weft straps near the inner edge of the reinforcement strap. It is possible that it is agricultural net was made through sequentially inserted in the cross-shaped in the yarn bundles.

    As described above, according to the agricultural net of the present invention, a plurality of warp cords and a plurality of weft cords are crossed into a graticule line so as to have a predetermined mesh size, and are combined into a square mesh. In the formed net-like body, one or two or more warps are passed in parallel within a predetermined plurality of adjacent warp pitch dimensions at predetermined intervals between both ends of the weft cords to form a reinforcing band portion. It is almost the same weight as ordinary conventional net products, has excellent handling operability at high places, and at least between the weft straps near the inner edge of the reinforcing band arranged at both ends of each weft strap It is assumed that the tying rope for tie-wearing set to a length exceeding the total length of the warp cord is inserted along with the joint, and the reinforcement belt part bears the tension transmitted from the tying rope to the net-like body at the time of netting. Endurance strength can be greatly improved, excellent dimensional maintenance and shape Exerts a lifting performance Zhang after casting of slack or misalignment, the adverse effects such as deformation reliably prevented, in which Su features is obtained that can exhibit high durability even pinching by fasteners such.

    In addition, the cross-sectional shape and dimensions of each of the weft cords that form the reinforcing band portion are the same as those of the weft cords that form the other net-like body portions in the agricultural net, and only the warp cords or the weft cords Compared to a net with a structure in which the density of either one is increased and the cross-sectional shape of a conventional warp is enlarged or changed, or a reinforcing material is laminated and heat-sealed at appropriate intervals on at least one side. A wide range of mesh bodies can be set to the appropriate dimensions according to the purpose of bird protection, protection, and animal protection, ensuring high daylighting and air permeability, and manufacturing with less increase in the number of materials used The effect of reducing man-hours will be demonstrated.

    Furthermore, each of the plurality of warps is made by twisting a plurality of strands, and a predetermined mesh size is provided between the strands of each of the plurality of warps. A plurality of weft strings, each of which is made by bundling a plurality of strands, are passed through a graticule to form a square mesh, and only a single strand is used As a result, the entire net can be manufactured, and an agricultural net excellent in production efficiency and economy can be provided.

    1 or 2 or more warps are passed in parallel through 100 to 2 adjacent warp pitches within a range of about 80 · in the weft strap direction width at intervals of 1 m between the ends of each weft strap. In the case where the reinforcing band portion is formed, about 90% or more of daylighting ability and air permeability can be secured as compared with the conventional net having no reinforcing band portion, and economical efficiency, handling workability, economical efficiency, etc. An agricultural net with excellent performance balance can be provided.

    Each of the plurality of warps is made by twisting a plurality of strands, and a part of the plurality of warps is separated from each lengthwise portion of each predetermined size. Stretch the middle part of the yarn, twist it between the strands of adjacent warp strands to form a binding shape, and form multiple weft strands consisting of bundle-like strands that cross substantially perpendicularly to each warp strand In the case of a reticulated mesh-like mesh formed by forming a square mesh that intersects the graticule, the entire mesh is produced by a single production process that is produced in the warp direction using an automatic mesh making machine. It is possible to manufacture an agricultural net with excellent production efficiency while obtaining the above-described reinforcing structure.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
The net-like body has a function that ensures a high durability by securing a mesh size that can be used for agriculture such as insect-proof, bird-proof, rod-proof, and beast-proof. A plurality of weft cords are crossed in a graticule shape so as to have a predetermined mesh size, and a square mesh is formed as a combined shape, and a plurality of adjacent ones at predetermined intervals in the weft cord direction. Each band within the warp pitch dimensions must be formed with a reinforcing band that is made by passing one or more warps in parallel, for example, a knot, no knot, cocoon net or woven In addition to being able to have an appearance such as a net, a synthetic resin-integrated net, or multiple warps twisted by twisting multiple strands are arranged in parallel, and each warp has a predetermined pitch Part of each yarn halfway part is stretched in a branching manner to the adjacent warp and twisted together to form a binding Forming a weft cord plurality as those obtained, which can be substantially like that weft cord a plurality of each via string is to form the net to intersect orthogonally shape.

    The warp string has the function of securing the strength in the crossing direction when the agricultural net is stretched in the form of a stretch and forming a meridian component of the mesh body, which is higher in tension than the weft string. The strength should be ensured, and as shown in the examples described later, a plurality of strands can be twisted together and formed from a single strand. The middle part of the yarn that is formed integrally with the weft string or part of the yarn that forms the warp string is pulled out at a certain pitch and attached to the middle part of the adjacent warp string. It is possible to form a string.

    The yarn functions to make it possible to form a weft string by twisting or bundling a plurality of yarns, and more specifically, it is made of natural cotton yarn, blended yarn or the like. Although it is possible to improve durability and waterproofness, it can be made of synthetic resin formed into a linear shape of polyester, vinylon, polypropylene, polyethylene, acrylic, nylon, rayon, acetate, etc. that can be reduced in weight, etc. In other words, it can be said that the wire material is 300 to 400 denier, preferably 380 denier, and below 300 denier, it can be used for insect-proofing, bird-proofing, rod-proofing or animal-proofing. However, if it exceeds 400 denier, the weight will increase and a net that is easy to handle at high places will not be provided. Are those, it can be said that it is desirable to use a 380 denier as performance balance between weight and strength of the net is the most su been.

    The weft cords are crossed with the warp cords to form a mesh of a predetermined mesh size, and fulfill the function of forming the weft-line component of the mesh body. Although it is not, it must be able to secure sufficient strength to suspend its own weight of the mesh and sufficient durability according to the purpose of bird protection, protection, and animal protection, as shown in the examples described later. As described above, a plurality of strands can be bundled, and can be formed from a single strand, and can be formed integrally with a warp or warp It is possible that the middle part of the partial yarn forming the thread is pulled out at a constant pitch and bound to the middle part of the adjacent weft string to form a meridian shape.

    Reinforcing band part is to fulfill the function of ensuring excellent dimensional maintenance and shape maintenance performance, as well as ensuring the daylighting and breathability etc. of the reticulated body, more specifically, It can be said that one or two or more warps are passed in parallel in a predetermined plurality of adjacent warp pitch dimensions at predetermined intervals between the ends of each weft cord. For example, one or more warps in each of 100 to 2 adjacent warp pitches within a range of about 80 · in the weft strap direction width at intervals of 1 m between the ends of each weft strap. It is possible to pass the strings in parallel, and moreover, between each weft string pitch corresponding to the band-shaped range to be formed, one or more weft strings, It can also be arranged so that it passes through the warps in a cross shape.

    The tie rope functions to make it possible to attach the reinforcing band of the mesh body near both ends to the object to be stretched, such as between a pipe house and a plurality of poles, with sufficient strength. It is provided near the inner edge of the reinforcement band part arranged on both ends of the cord, and is longer than the overall length of each warp cord (mesh spanning width), and can be connected to both ends. It should be long enough to maintain a sufficient contact area, and should be set to a thickness that can maintain a sufficient contact area. For each of the weft strings adjacent to each other, it can be alternately passed from the front and back sides, or can be sequentially inserted into the strand of adjacent weft strings in a cross shape, etc. In addition to natural cotton yarn and blended yarn, etc., it has excellent durability and waterproofness and is lightweight. Polyester capable, vinylon, polypropylene, polyethylene, can be acrylic, nylon, rayon, synthetic resin yarn-making molded acetate or the like to a linear string, and the like that twisted into rope form.
