Description

  The present invention relates to a wire mesh obtained by weaving metal yarn warp and weft with an automatic loom.

  Wire mesh produced by weaving metal wires with an automatic loom is used in a wide range of fields such as screen printing plates, filters, and sieves. From a 2-mesh wire mesh with a coarse opening to a 4000-mesh wire mesh with a very fine opening, it is possible to manufacture with an automatic loom. Here, the mesh means the number of metal wires existing in a width of 1 inch. For example, in the case of 50 mesh, 50 metal wires exist in a width of 1 inch. The wire mesh is composed of warp and weft, but if the number of warp per inch and the number of weft are the same, for example, it is simply 5 mesh. When the number of warp yarns is different from the number of weft yarns, the vertical mesh is 10 mesh and the horizontal mesh is 50 mesh.

  For example, a wire mesh filter described in Patent Document 1 is known as a filter having a small opening (a large mesh). In the wire mesh described in Patent Document 2, the portions overlapping each other are crushed and brought into contact with each other, so that the thickness is reduced in the thickness direction. Wire mesh made by weaving metal wires is often used for filters, screen printing plates, etc. If the mesh is small, finer filtration is possible and finer printing is possible. There are advantages such as. Further, if the thickness of the wire mesh is reduced, there is an advantage that the thickness of the entire filter can be reduced or the thickness of the ink can be reduced. Therefore, as in Patent Documents 1 and 2, there is a high need for a wire mesh with a small opening or a wire mesh with a small thickness.

  FIG. 1 is a schematic side view showing a functional structure of an automatic loom 1 for manufacturing a wire mesh according to an embodiment of the present invention. FIG. 2 is a schematic front view showing a functional structure of the automatic loom 1. The automatic loom 1 includes a drum 2, a first warp feeding device 3, hooks 4 a and 4 b, a kite 5, a rapier 6, a winding device 7, a bobbin 10, a weft sending device 11, And a guiding jig 12. The automatic loom 1 has a first warp feeding device 3 for aligning the direction so that the warp yarn 8 is not twisted and the weft yarn 9 is not twisted with respect to a general rapier type automatic loom. A feature is that a weft feeding device 11 for aligning the directions is added.

  First, the basic structure of the automatic loom 1 will be described. The warp yarn 8 is wound around the drum 2 by the warping process. The warp 8 wound around the drum 2 is passed through the reeds 4a, 4b and reed 5 and attached to the winding device 7. The ridges 4a and 4b move up and down in opposite directions to create a gap between the warp yarns 8. The rapier 6 is inserted into the gap. The guiding jig 12 is a jig for hooking the weft 9 and guiding it to the rapier 6. The rapier 9 hooks the weft 9 extending from the bobbin 10 at the tip of the guide jig 12 and passes the weft 9 between the warps 8. When the weft thread 9 is passed, the heel 5 moves and the weft thread 9 is woven between the warp threads 8. When the weft yarn 9 is woven, both ends of the weft yarn 9 are cut, the hooks 4a and 4b move up and down, the rapier 6 returns to the original position, the weft yarn 9 is hooked again, and the weaving operation is repeated. The winding device 7 sequentially winds the woven wire mesh. The basic operation of such an automatic loom is the same as before, and a commercially available automatic loom can be used. In addition, since it changes suitably according to the weaving methods, such as the number of the collars 4a and 4b and the structure of the rapier 6, it is not limited to the illustrated example. As the weaving method, plain weave, twill weave, plain tatami weave, twill tatami weave and the like can be used.

  In this embodiment, a metal wire having a non-circular cross section is used as the warp yarn 8 and / or the weft yarn 9. A metal wire having a non-circular cross section is referred to as a deformed metal wire. The irregular metal wire includes a flat wire with a square cross section (including chamfered ends), a trapezoidal trapezoidal cross section (including chamfered ends), and a polygonal cross section (end Polygonal lines with a chamfered part), oval lines with an elliptical cross section, rhombus lines with a rhombus cross section (including those with chamfered ends), barrel lines with a cross section in a barrel shape, etc. However, it is not limited to these. Stainless steel, brass, red copper, phosphor bronze, etc. are used as the material for the irregular shaped metal wire, but are not limited thereto.

  The deformed metal wire may be used only for the warp yarn 8, may be used only for the weft yarn 9, or may be used for both the warp yarn 8 and the weft yarn 9. When a deformed metal wire is used for the warp yarn 8 and a round wire having a circular cross section is used for the weft yarn 9, the drum 2 and the first warp yarn are warped with the directions aligned so that the warp yarn 8 is not twisted. The weft delivery device 11 is not required to be used with the delivery device 3. When a round wire is used for the warp yarn 8 and a round wire is used for the weft yarn 9, the drum 2 having a warped round wire is used as before, and the first warp feeding device 3 need not be used. When using a deformed metal wire for both the warp yarn 8 and the weft yarn 9, the drum 2, the first warp yarn feeding device 3, and the weft yarn that are warped in the same direction so that the warp yarn 8 is not twisted are used. The delivery device 11 is used.

  Even if a deformed metal wire is used in a conventional automatic loom as it is, the metal wire may be twisted and the directions may not match. The present invention is characterized in that the directions are aligned so that twisting does not occur.

  In order to prevent the weft 9 from being twisted, the weft delivery device 11 is used in this embodiment. The weft 9 obtained from the bobbin 10 is sandwiched between the upper weft roller device 11a and the lower weft roller device 11b so as not to twist. The upper weft roller device 11a and the lower weft roller device 11b are rotated in opposite directions by power. By rotating the upper weft yarn roller device 11a and the lower weft yarn roller device 11b, the directions are aligned so that the pinched weft yarns are not twisted and fed to the guiding jig 12 side. The rapier 6 can be hooked and weaved between the warps 8 by the wefts 9 aligned in this way.

  In addition, since the weft 9 wound around the bobbin 10 is provided by a metal wire manufacturer, it is unclear whether or not twisting has occurred. It is possible to hook the weft thread 9 on the rapier 6 after eliminating the twisting. Since the direction of the weft 9 wound around the bobbin 10 is aligned, if the weft 9 can be hooked on the rapier 6 so that the weft 9 is not twisted, the weft delivery device 11 is not used. May be. Therefore, the wire mesh of the present invention is characterized by using a deformed metal wire that is not twisted, and the wire mesh manufactured without using the weft delivery device 11 also belongs to the scope of the present invention. In addition, as a mechanism for preventing the weft 9 from being twisted, a roller sandwiched between the upper and lower sides is used, but other mechanisms may be employed in the weft sending device 11. Moreover, when pinching with a roller, you may pinch other than upper and lower sides.

  In order to prevent the warp of the warp yarn 8 from occurring, first, it is necessary to wind the warp yarn 8 around the drum in the same direction so that the warp does not occur at the stage of the warping process. FIG. 3 is a schematic side view showing a functional structure of the warping device 13 used in the warping process. In FIG. 3, the warping device 13 includes a drum 2, a second warp feeding device 14, support portions 15, 16, 18 a, 18 b, 18 c, and bobbins 19 a, 19 b, 19 c. In FIG. 3, an enlarged view surrounded by a circular dotted line is a schematic enlarged plan view shown for easy understanding of the relationship between the warps 17a, 17b, and 17c.

  The plurality of bobbins 19a, 19b, 19c are rotatably attached to a columnar jig (not shown). A plurality of bobbins 19a in the longitudinal direction form a set, and the warp 17a obtained from the plurality of bobbins 19a is changed in angle by the support portion 18a and is stretched in the direction of the support portion 16. The same applies to the other bobbins 19b and 19c. The warps 17a, 17b, and 17c extending from the bobbins 19a, 19b, and 19c are further gathered together in the support portion 16. When the warp yarns 17a, 17b, and 17c are gathered together in the support portion 16, the upper warp roller device 14a and the upper warp roller device 14a of the second warp yarn feeding device 14 are placed on the lower warp yarns 17a, 17b, and 17c so that twisting does not occur. The direction is aligned with the warp roller device 14b. The upper warp roller device 14a and the lower warp roller device 14b are rotated in opposite directions by power. Accordingly, the warp yarns 17a, 17b, and 17c having the same direction are sent out from the second warp yarn feeding device 14. The sent warp yarns 17 a, 17 b, and 17 c are changed in angle by the support portion 15 and wound around the drum 2. The drum 2 is rotated by power and sequentially winds the warp yarns 17a, 17b, and 17c so as not to be twisted.

  The number of warps 17a, 17b, 17c is appropriately selected according to the number of meshes of the wire mesh. Further, the warp yarns 17a, 17b, and 17c corresponding to the width of the wire mesh may be wound around the drum 2 at once, but the partial adjustment is performed such that the warp yarns 17a, 17b, and 17c are partially wound around the drum 2 in a plurality of times. The drum 2 may be completed by way of warp. The drum 2 obtained as described above is set in the automatic loom 1. Note that since the directions of the warp yarns wound around the bobbins 19a, 19b, and 19c are aligned, the second warp yarn feeding device 14 can be used as long as the warp yarns can be wound around the drum 2 so that the warp yarns are not twisted. May not be used. Therefore, the wire mesh of the present invention is characterized by using a deformed metal wire that is not twisted, and the wire mesh manufactured without using the second warp feeding device 14 also belongs to the scope of the present invention. Further, as a mechanism for preventing the warp of the warp from occurring, a roller sandwiched between the upper and lower sides is used. However, other mechanisms may be employed in the second warp-feeding device 14. Moreover, when pinching with a roller, you may pinch other than upper and lower sides.

  The automatic loom 1 is provided with a first warp feeding device 3. When the warp yarn 8 taken up from the drum 2 is passed through the reeds 4a, 4b, reed 5 and the take-up device 7, it must not be twisted. Therefore, the warp yarn 8 is sandwiched between the upper warp yarn roller device 3a and the lower warp yarn roller device 3b. Since the upper warp roller device 3a and the lower warp roller device 3b are rotated in opposite directions by power, the sandwiched warp yarn 8 is sent to the winding device 7 without being twisted. .

  At the stage where the weaving operation starts, the pinching by the upper warp roller device 3a and the lower warp roller device 3b may be released, or the weaving operation may be performed while the warp yarn 8 is sandwiched. In addition, since the warp 8 is not twisted when it is wound around the drum 2, if the warp 8 can be wound without twisting the winding device 7, the first warp feed The device 3 may not be used. Therefore, the wire mesh of the present invention is characterized by using a deformed metal wire that is not twisted, and the wire mesh manufactured without using the first warp feeding device 3 also belongs to the scope of the present invention. Further, as a mechanism for preventing the warp from twisting, a roller sandwiched between the upper and lower sides is used, but other mechanisms may be employed in the first warp feeding device 3. Moreover, when pinching with a roller, you may pinch other than upper and lower sides.

  Thus, by using the automatic loom 1, when using a deformed metal wire as the warp and / or weft, it is possible to manufacture a wire mesh that is woven in the same direction so as not to twist. By using a deformed metal wire as the warp and / or weft, it is possible to provide a thin wire net with a small opening.

  A wire mesh manufactured according to the present embodiment is shown as an example in FIGS. FIG. 4 is an enlarged photomicrograph of a 100 mesh plain weave wire mesh. A flat wire is used as the warp and a round wire is used as the weft. As shown in FIG. 4, the flat wires are woven in a uniform direction without twisting. It can also be confirmed that the opening is square. Regarding the thickness direction of the wire mesh shown in FIG. 4, since the warp is a flat wire, it is thinner than when a round wire is used for the warp. Since the thickness is reduced and the opening is a quadrangular shape, when the opening is viewed three-dimensionally, it is generally a cubic shape. When round lines are used for both warp and weft, the opening is square in plan view, but when viewed three-dimensionally, the opening warps inward due to the curved surface of the round line instead of a cube. It becomes a distorted opening structure. Thus, when a flat wire is used for the warp and / or the weft, the shape of the opening is square compared to the case where both the round wires are used.

  FIG. 5 is an enlarged micrograph of a 1400 mesh twilled woven wire mesh. A round wire is used as the warp and a flat wire is used as the weft. As shown in FIG. 5, the flat lines are woven without being twisted in the same direction. It can be seen that the opening is a shape in which the space on the weft side is straightened by the amount that the weft is a flat wire. Moreover, since the weft is a flat wire, it turns out that thickness is thin. If the weft is a round line, the thickness will increase and the opening will have a more distorted shape. If a flat line is used in this way, the space shape of the opening can be reduced.

  FIG. 6 is an enlarged micrograph of a 2400 mesh twilled woven wire mesh. FIG. 7 is an enlarged micrograph of a 2500 mesh twilled woven wire mesh. 6 and 7 both use a round wire as the warp and a flat wire as the weft. 6 and 7, the cross section is cut so as to be easily understood. 6 and 7, it can be seen that the flat lines are woven without being twisted in the same direction. As can be understood from the assumption that the weft is a round line, it can be seen that in these examples, the thickness is reduced, the shape of the opening is also angular, and the spatial shape is reduced.

  FIG. 8 is an enlarged micrograph of a 2500 mesh plain woven wire mesh. The embodiment of FIG. 8 uses a flat wire as the warp and a round wire as the weft. Also in the embodiment of FIG. 8, it can be seen that the flat lines are woven without being twisted. As can be seen from the assumption that the warp was a round line, it can be seen that in these examples, the thickness is reduced, the shape of the opening is also angular, and the spatial shape is reduced.

  FIG. 9 is an enlarged micrograph of a 2200 mesh plain woven wire mesh. In FIG. 9, the example is woven into the A region using the flat wire for the warp and the round wire for the weft, and the comparative example is woven into the B region using the round wire for both. As can be seen from the cross section of FIG. 9, the thickness of the embodiment is clearly thinner. The opening is also a square shape compared to the comparative example because the flat wire is used for the warp, and the space shape is small. In the comparative example, the opening has a distorted shape with many curved portions.

  FIG. 10 is an enlarged micrograph of a 2200 mesh plain woven wire mesh. In FIG. 10, the example is woven into the D region using the flat wire for the warp and the round wire for the weft, and the comparative example is woven into the C region using the round wire for both. As can be seen from the cross section of FIG. 10, the thickness of the embodiment is clearly thinner. The opening is also a square shape compared to the comparative example because the flat wire is used for the warp, and the space shape is small. In the comparative example, the opening has a distorted shape with many curved portions.

In the above-described embodiment, a wire mesh having 100 to 2500 meshes is shown as the number of meshes. However, the number of meshes of the wire mesh shown in the above-described embodiment is merely an example, and the present invention is not limited thereto. In the rapier loom owned by the present applicant, it is possible to manufacture a wire mesh at least within the following range.
Iron loom: 0.3φ × 20m / s ~ 0.11φ × 100m / s (Twill / Plain)
Cotton loom: 0.12φ x 60m / s to 0.02φ x 635m / s (Twill / Plain)
Iron loom: 0.38φ / 0.26φ × 24/110
Cotton loom: 0.14φ / 0.11φ × 50 / 250m / s to 0.025φ / 0.015φ × 500 / 3600m / s
Therefore, when weaving warp and / or weft with irregular lines using the embodiment of the present invention, as the number of meshes, a wire mesh having a warp mesh and / or a weft mesh of 2 mesh or more is manufactured using this embodiment. It is possible. In view of obtaining the advantage of using a deformed line, the present invention is preferably used for a wire mesh having a vertical mesh and / or a horizontal mesh of 5 mesh or more. Further, as a finer metal mesh, a metal mesh of 20 mesh or more and 500/3600 mesh (a vertical mesh is 500 and a horizontal mesh is 3600; the same applies hereinafter) can be manufactured using this embodiment. If it is an opening, it is possible to manufacture a wire mesh having a opening in the longitudinal direction of 5 mm or less using this embodiment. Of course, it is possible to manufacture a finer wire mesh by using a loom other than the loom owned by the present applicant. There has never been a wire mesh using a deformed metal wire while having such a fine mesh number and opening.

  In the above embodiment, the case where both the warp and the weft are flat lines is not shown, but since the manufacture of the embodiment when only the warp is a flat line and only the weft is a flat line, both have been successfully manufactured. Even if it is a flat wire, it can be said that it can be produced without any problems. Moreover, although the case of a twill weave is not shown in the said Example, since it has succeeded in the manufacture of a plain weave, a plain tatami weave, and a twill woven weave, it can be said that a twill weave can also be manufactured without a problem. In the above example, the case where a deformed metal wire other than a flat wire is used is not shown, but as in the present embodiment, if the deformed metal wire is sandwiched with the upper and lower roller devices aligned in the direction, It can be said that metal wires can be woven without twisting.

  The wire mesh shown in the present embodiment can be used for, for example, a filter, a screen printing plate, and a sieve.

  When used in a filter, the wire mesh portion can be made thin, so that when the multi-way mesh is stacked and used in the filter, the thickness of the entire filter can be reduced. As a result, the filtration resistance is lowered, and the life of the filter is increased. Further, since the space shape of the opening is small, the filtration accuracy is improved. If the wire mesh of this invention is used, it is possible to manufacture the wire mesh which has a filter hole smaller than 5 micrometers which is the minimum filter hole in the applicant's conventional wire mesh, and a filter can also make a filter hole small according to it.

Moreover, when using a wire mesh for a filter, it can use for what is called a sintered filter which laminates | stacks a some filter and bakes and sinters in a heating furnace. For example, the sintered filter is manufactured by sintering 4-5 layers of a metal mesh such as a protective layer, a filtration control layer, a dispersion layer, a reinforcing layer, and a reinforcing layer in a vacuum furnace. If the wire mesh of the present invention is used for at least one of these layers, the thickness of the entire sintered filter can be reduced. The following is an example of a combination of wire meshes to be laminated.
Plain weave / Twill weave: 0.37φ × 20m / s ～ 0.02φ × 635m / s
Tatami weave: 0.57φ / 0.43φ × 12 / 64m / s ~ 0.025φ / 0.015φ × 500 / 3600mesh
For example, when the combination of wire meshes is expressed by the number of meshes, there are the following examples.
Protective layer, filtration control layer, dispersion layer, reinforcing layer, reinforcing layer
(100,500 / 3500,100,12 / 64,64 / 12)
(100,400 / 3000,100,12 / 64,64 / 12)
(100,325 / 2400,100,12 / 64,64 / 12)
(100,250 / 1600,100,12 / 64,64 / 12)
(100,200 / 1400,100,12 / 64,64 / 12)
(100,165 / 1400,100,12 / 64,64 / 12)
(100,165 / 1200,100,12 / 64,64 / 12)
(100,165 / 800,100,12 / 64,64 / 12)
(100,50 / 250,100,12 / 64,64 / 12)
(100,200,100,12 / 64,64 / 12)
(100,150,100,12 / 64,64 / 12)
Needless to say, the number of layers and the number of meshes are not limited to the above example. If the wire mesh of this invention is used for a sintered filter, the thickness of the whole filter can be made thin and filtration resistance can be lowered | hung.

  When the wire mesh of the present invention is used for a screen plate for screen printing, the plate can be made thin. If the plate is thinned, the ink can be printed thinly. Moreover, since the shape of the opening is an angular shape, the outline of the printed material can be sharpened.

  In the case where the wire mesh of the present invention is used for sieving, since the space shape of the opening is an angular shape, an improvement in the accuracy of sieving can be expected.

  In this embodiment, an automatic loom using a rapier is used. However, the present invention can also be applied to an automatic loom using a shuttle. First, when the weft is a round wire and the warp is an irregular metal wire, the round wire wound around the shuttle can be used as it is in the conventional structure, so the warp is wrapped around the beam in the same manner as in this embodiment. The wire mesh of the present invention can be manufactured by preventing twisting at the setting stage of the automatic loom. In the case of using a deformed metal wire as the weft, when the weft is wound around the shuttle, for example, the weft may be wound around the shuttle while aligning the direction so that the upper and lower roller devices do not twist the weft. By using the shuttle with the wefts wound around in this way, the wefts can also be woven so as not to be twisted. Further, the shuttle itself may be provided with a mechanism for sandwiching the weft yarn between the two rollers to prevent twisting. Thus, the automatic loom used for carrying out the present invention is not limited to the rapier type automatic loom.

  Although the present invention has been described in detail above, the above description is merely illustrative of the present invention in all respects and is not intended to limit the scope thereof. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention.

  The present invention relates to a wire mesh and can be used industrially.
