Description

  The present invention relates to a wire mesh used for manufacturing a wire mesh-containing glass plate used for architectural window glass, and more particularly to a rhombus welded wire mesh with a salvage wire.

  A glass plate with a wire mesh is excellent in preventing scattering of glass pieces when broken, is excellent in preventing scattering, is supported by a wire mesh even if it breaks, and has a function of preventing similar burning in a fire and is widely used as a window glass for construction.

  As a wire mesh strip to be enclosed in this wire mesh-filled glass plate, the length of the mesh strip is placed on a number of straight metal wires A arranged in parallel at predetermined intervals in an oblique direction of about 45 degrees with respect to the length direction. A plurality of linear metal lines B arranged in parallel at the predetermined intervals in an oblique direction opposite to the metal line A at approximately 45 degrees with respect to the vertical direction are overlapped, and two adjacent metal lines A and Each metal wire A and each metal wire B are welded to each other at the position of each crossing point in a state where the two adjacent metal wires B cross each other to form a square or rhombus network. Ryonet strips are widely used.

In the production of a wire mesh-containing glass plate, when the rhomboid strip is inserted into the ribbon-like glass, the mesh strip is pulled and inserted, but when the tensile force changes, the mesh shape is easily deformed. In order to prevent such deformation, by using a salvage wire-attached rhombus welded wire mesh band in which the salvage wire is welded along both edges in the width direction of the rhombic belt body and both edges of the mesh belt body are constrained, It is known from Patent Document 1, Patent Document 2 and Patent Document 3 that deformation can be prevented.
WO2003 / 028919 (pages 21-22) JP 2007-001776 A JP 2007-153663 A

  This salvage wire-attached rhombus welded wire mesh band is wound on a winding roll during the net making, and when it is wound on the roll after surface treatment such as plating after the net making, an external force is applied in the length direction. Added. The mesh portion of the wire mesh band where the metal wires are obliquely welded at about 45 degrees is easily deformed by the tensile external force, but when the wire mesh belt is unwound from the winding roll and the tensile external force is lost, the original mesh is removed. Restore shape. This tensile external force exerts a stress within the bending elastic limit on the metal wire in the mesh portion of the wire mesh band. However, since the stress exceeds the elastic limit on the salvage wire, the salvage wire undergoes plastic deformation (elongation), and tensile Even if the external force is eliminated, it does not shrink and does not return to its original length. Therefore, in the state where it has been unwound from the winding roll, a difference in length occurs between the central portion in the width direction of the wire mesh strip and the salvage wire near both edges. As a result, when the wire mesh strip wound around the winding roll is unwound and spread on a flat surface, the length of the both ends of the wire mesh strip is longer than the central portion in the width direction. Waves in the thickness direction occur. When manufacturing a glass sheet with a wire mesh, if the wire mesh is enclosed in a glass strip with the edges undulated in this way, the mesh depth in the glass will not be constant, sometimes protruding from the glass, or at the edge of the mesh There are inconveniences such as bending and overlapping.

  The object of the present invention is to remove the problems of the prior art as described above and provide a rhombus welded wire mesh strip with a salvage wire for a meshed glass plate with small waviness in the thickness direction at both edges of the wire mesh strip width direction. There is to do.

  That is, the present invention is a rhombus band for a meshed glass plate, comprising a number of linear metal wires A arranged in parallel at predetermined intervals in an oblique direction with a predetermined angle with respect to the length direction of the net band. On top of this, a large number of linear metal wires B arranged in parallel at the predetermined intervals in an oblique direction opposite to the metal lines A at the same angle as the predetermined angle with respect to the length direction of the net-like body. In the state where two adjacent metal lines A and two adjacent metal lines B cross each other to form a square or rhombus network, each metal line A and each metal line B Are welded to each other at each crossing point, and salvage lines are arranged on the mesh strip along the respective edges on both sides in the width direction. The salvage lines are connected to the metal lines A in contact with the salvage lines. Welded to each other at each crossing point with the crossing point and metal wire B, The distance between the two adjacent weld points is shortened by plastic bending deformation of the salvage line portion between the two weld points so as to bend at the intermediate portion thereof, and the distance between the adjacent metal lines at the edge of the mesh band is This is a rhombus band for a glass sheet with a mesh that is made to approach the interval between adjacent metal wires in the center of the band.

Hereinafter, the present invention will be described in detail with reference to examples.
As shown in FIGS. 1 and 2, the rhomboid strip for a glass-containing glass plate of the present invention has a predetermined interval α, for example, about 20 mm in an oblique direction with a predetermined angle α, for example, about 45 degrees with respect to the length direction 2 of the net strip 1. And a large number of linear metal lines A3 arranged in parallel with each other, and the same length as the predetermined angle with respect to the longitudinal direction 2 of the net-like body, which is superimposed thereon, is about 45 degrees opposite to the line A3. A large number of linear metal wires B4 arranged in parallel in the oblique direction at the predetermined interval of about 20 mm, and a salvage wire 5 along each edge on both sides in the width direction of the mesh band, The metal wire A3 and the metal wire B4 are welded at the crossing point 6, the metal wire A3 and the salvage wire 5 are welded at the crossing point 7, and the metal wire B4 and the salvage wire 5 are welded at the crossing point 7 ′, respectively. Yes. The adjacent metal line A3 and the adjacent metal line B4 form a square or rhombus mesh 8. The salvage wire 5 is preferably welded to the metal wires A and B while avoiding the intersection 6 between the metal wire A3 and the metal wire B4. This is because the thickness of the net-like body increases when the intersection 6 and the intersections 7 and 7 'overlap. It is more preferable to arrange the salvage line 5 so that the crossing points 7 and 7 'are located at approximately the center of each of the two sides (metal lines A and B) of the mesh.

  As shown in FIG. 3, the salvage wire metal portion 5 between the weld points 7 and 7 'of the adjacent metal wire A3, metal wire B4, and salvage wire 5 is a direction crossing the length direction of the salvage wire, for example, an arrow from above. By pressing as shown in FIG. 2, the plastic bending deformation is performed so as to bend at an intermediate portion thereof to become 5 ′, and the metal wires A3 and B4 become 3 ′ and 4 ′, respectively. A difference between the most bent portion and the original position is defined as a bending value d. The average value of the bending values d at 20 locations of the salvage line portion 5 continuous along the length of the belt-like body is defined as the average bending value. Since the length of the salvage line portion 5 between the two welding points itself is bent and deformed, the distance between the two welding points 7 and 7 'decreases from K to k'. Accordingly, the interval between adjacent metal lines A3 and the interval between adjacent metal lines B4 are also shortened.

  If the plastic bending deformation of the salvage line between the two weld points is not performed, the distance between the adjacent metal wires in the center of the mesh band is expanded by elastic bending deformation of the metal wires A and B due to the tensile external force during knitting. On the other hand, in the vicinity of the salvage line at the other edge of the mesh, the interval between the adjacent metal lines is expanded to substantially the same interval as described above due to the plastic elongation of the salvage line. When the net wound in this state is fed out from the take-up roll, the tensile external force is released and the interval between the adjacent metal wires at the center of the mesh returns to the original interval, but the salvage is near the salvage line at the net edge. The distance between the metal lines near the welded part of the line remains unchanged. Therefore, undulation is generated in the net due to the difference in the interval. In the case of the present invention, the interval between the metal wires at the welded portion of the salvage wire is shortened, so in the net fed from the take-up roll, the interval between the adjacent metal wires at the center of the mesh and the adjacent metal wires at the edge of the mesh The difference from the interval is reduced, and undulation is prevented.

  The direction and direction of plastic bending deformation so that each salvage line portion between two adjacent metal wires and adjacent weld points of the salvage wire 5 is curved at the intermediate portion thereof is as shown in FIG. In addition to bending inward in the direction, it may be curved outward in the thickness direction of the mesh as shown in FIG. 4, or inward in the width direction of the mesh as shown in FIG. 5 or as shown in FIG. Thus, it can be respectively curved outward in the width direction of the net, or a direction and direction in which these are combined can be taken. Among these, as shown in FIG. 3, it is preferable to bend inward in the thickness direction of the net because it can be most easily performed.

  One of the specific methods of plastic bending deformation so that the salvage line between the two adjacent welding points is curved is that of the salvage line of the net-like body traveling on the take-up roll, transport roll and other supports. A cylindrical or frustoconical presser is placed on top of the presser and the salvage wire is continuously pressed by its own weight while freely rotating the presser. Can be bent. According to this, the welded portion between the salvage wire and the metal wire B hardly deforms because the load of the presser is dispersed, but the intermediate portion between the welded portion of the salvage wire and the welded portion is plastically bent downward by the load of the presser. Deform. Instead of pressurization by the weight of the presser, the pressurizer may be pressurized using hydraulic pressure or the like. In addition, if a roll having radial protrusions at the end is pressed against the salvage wire before winding from the bottom and pressed from the opposite side of the thickness direction of the mesh strip, the portion of the salvage wire between the welding points will be It can be bent outward in the thickness direction. When the salvage wire is bent in the thickness direction as described above, it is preferable to bend the thickness inward because it is easier to operate than to bend the thickness outward.

  As an example of a specific method of bending the salvage line in the width direction of the net, a roll having radial conical protrusions or hemispherical protrusions at the end is placed slightly above the salvage line from the top or bottom of the salvage line. By shifting in the width direction, for example, inward in the width direction and pressing the line sideways, the welded portion of the salvage wire and the intermediate portion of the welded portion can be curved outward in the width direction of the net. Further, if the center of the protrusion is shifted outward in the width direction of the salvage line, the welded portion of the salvage wire and the intermediate portion of the welded portion can be curved outward in the width direction of the net.

  If the degree of plastic bending deformation is too small, the effect of preventing undulation will not be sufficient. Conversely, if it is too large, the central part of the net will be deformed into a convex or concave shape. The appropriate range of plastic bending deformation varies depending on the individual knitting network device, the material of the mesh wire and the salvage wire, the size, the mesh size of the mesh, etc., but the adjacent two metal wires and the salvage wire are adjacent to each other. When plastic bending deformation is performed so that each salvage line portion between the points is bent at the intermediate portion, the bending value (d in FIG. 3) of the intermediate portion is a depth of 0.10 to 0.50 mm as an average value. Or it is preferable to set it as the width. This value can be controlled by adjusting the load, size, etc. of the pressing element.

  When winding the braided net on a take-up roll, the salvage wire, metal wire B, and salvage wire are the places where each salvage wire portion between adjacent welding points is plastically deformed so as to bend at the intermediate portion. Can be any of the process of welding the steel, the transporting process, and the process of winding on a take-up roll, but it is most effective after or at the time when the largest tensile external force is applied. Most preferably, it is performed in a step of winding around a roll. If the plastic bending deformation is performed before the tensile external force is applied, the bending disappears when the tensile external force is applied thereafter, so that the effect of preventing undulation cannot be obtained.

  Compared to the tensile external force that acts on the mesh band in the above case to wind up the woven mesh band, the tension that acts on the mesh band when the woven mesh is wound after surface treatment such as plating. Since the external force is generally large, the latter is more likely to be wavy in the prior art. Therefore, when winding the net by plating or other surface treatment, the locations of the plastic bend deformation so that each salvage line portion between the welding points is bent at the intermediate portion are the pretreatment step, plating step, and cleaning. Any of the process, the drying process, and the winding process may be performed, but it is most effective to be performed after or at the time when the largest tensile external force is applied. It is preferable to perform plastic bending deformation in the process.

  The above describes the case of plastic bending deformation so that the salvage line portion between two adjacent welding points of two adjacent metal wires and the salvage wire is bent at the intermediate portion thereof, as described below, The same effect can be obtained when the salvage wire portions between the two welding points of two metal wires and salvage wires adjacent to each other are separated by plastic bending so that the salvage wire portion is curved at the intermediate portion thereof.

  As shown in FIG. 7, a salvage line portion 15 between two welding points 14, 14 of two adjacent metal wires B <b> 11, 11 and a salvage wire 13 with one metal wire A <b> 10 in between is an intermediate portion thereof. It is plastically bent and deformed to be curved and becomes 15 '. Accordingly, the metal wire A10 and the metal wires B11, 11 are respectively 10 '. 11 '. Move to 11 '. Since the length of the salvage line portion 15 between the two welding points itself is bent and deformed, the distance M between the two welding points 14 and 14 is shortened, and the distance M between the adjacent metal wires B14 ′ and 14 ′. 'become. In this way, the distance between the two welding points is shortened, and the distance measured along the mesh band plane of the adjacent metal line at the edge of the mesh band is made closer to the distance between the adjacent metal lines at the center of the mesh band. As a result, in the net fed from the take-up roll, the difference between the distance between the adjacent metal lines at the center of the net and the distance between the adjacent metal lines at the net edge is reduced, thereby preventing undulation. The bending value (d in FIG. 7) of the intermediate part is preferably an average value of a depth of 0.20 to 1.0 mm.

  The plastic bending deformation of the salvage wire portion can be performed, for example, by curving in the thickness direction of the net in the salvage wire welding process as described below.

  As shown in FIG. 8 and FIG. 9, the salvage wire is welded by supplying the salvage wire 18 from above while intermittently feeding the wire mesh welded with the metal wire A <b> 16 and the metal wire B <b> 17 in the direction indicated by the arrows two by two. Then, when the lower electrode plate 19 and the two upper electrode bars 20 and 21 have two adjacent intersections between the metal line B17 and the salvage line 18 between the two electrodes, the two upper electrode bars 20 , 21 is lowered, the portion of the salvage wire 18 in contact with the upper electrode rod 20 is pushed down, and the upper electrode rod is energized and welded in the pressed state. A metal wire is formed by providing a vertical step at a position where the two intersections on the lower electrode plate 19 are pressed and pressing and welding the lower end surfaces of the two upper electrode bars with a vertical difference corresponding to the lower electrode step. A step in the thickness direction can be added to each welding point of B17 and the salvage wire.

  As another example of plastic bending deformation of the salvage line portion, a presser is installed above the salvage line in the process of advancing a knitted net or a surface-treated net toward the winding roll, and passes there One of the metal wires A and B to be detected, for example, the metal wire A is detected, and the welding point between the salvage wire and the metal wire A is pressed to bend inward in the thickness direction of the net.

  The metal wires and salvage wires that make up the wire mesh are made of mild steel or ferritic stainless steel, and these wires are subjected to surface treatment such as chemical polishing or nickel plating, chrome plating, or tin plating as necessary. The applied one is used. Those having a diameter of 0.35 to 0.65 mm are preferably used.

As the mesh to be knitted, a mesh having a mesh size of 16 to 21 mm on one side and a rhombus shape close to a square or a square is preferably manufactured.
The rhomboid wire mesh band is stretched in the direction of travel when inserted into the glass band, and the rhombus shape of the wire mesh net is deformed into a shape extending in the above direction of travel. For the metal lines A and B constituting the mesh, a wire mesh disposed at an angle larger than 45 degrees, preferably an inclination angle of 46 to 49 degrees, with respect to the length direction of the mesh band is preferably used.

  In the case of enclosing a wire mesh band in glass, a meshed glass plate is produced by setting the mesh feed rate slightly lower than the glass feed rate to prevent sagging. For this reason, naturally, a tension | tensile_strength is applied to a net | network and a net | network is stretched before enclosing in glass or glass. Since the tension tends to concentrate on the salvage line, accidents that cause the salvage line to break have been easy to occur. According to the present invention, by bending the salvage line in advance, the tension is relaxed so that the bent portion is straightened, so that the salvage line can be prevented from being cut.

According to the present invention, a rhombus welded wire mesh strip with a salvage wire with small waviness in the thickness direction at both edges in the width direction is obtained, and a meshed glass plate with a constant mesh depth in glass is produced using this. can do.
Furthermore, according to the present invention, it is possible to prevent the breakage of salvage wire, which has been easy to occur in the past when the wire mesh is enclosed in glass.

Embodiments of the present invention will be specifically described below.
FIG. 10 shows a knitting net apparatus for producing a net-like band for a glass sheet with mesh according to the present invention. The braided netting device includes a wire lead-out portion that draws a metal wire such as a stainless steel wire and cross-arranges it to form a metal wire intersection, a fixing means that forms a net by welding and fixing the intersection of each metal wire, and a metal wire such as a wire A salvage wire fixing means for pulling out a salvage wire made of stainless steel wire and placing it on both edges of the metal wire intersection and welding and fixing the intersection of the salvage wire and the metal wire, and FIG. A take-up roll and a presser are provided that wind while pulling in the lower right direction.

  The wire lead-out portion 31 has an underline trolley 35A that pulls out the metal wire A41 from a bobbin (not shown) around which the metal wire A41 is wound, and an upper line side that pulls out the metal wire B42 from a bobbin (not shown) around which the metal wire B42 is wound. There is a truck 35B, and a conveyor 35C that conveys a wire material crossing 43 in which the metal wire A41 and the metal wire B42 are crossed by the underline truck 35A and the upper line truck 35B.

  The underline trolley 35A and the upper line trolley 35B are oriented at an angle of about 45 degrees with respect to the transport direction of the net-like body 44 to be manufactured and in different directions. Accordingly, the underline-side trolley 35A and the upper-line side trolley 35B reciprocate the metal wire A41 and the metal wire B42 at an angle of approximately 45 degrees with respect to the transport direction of the net-like body 44 to be manufactured and at different intervals in different directions. Supply while letting.

  Therefore, such a wire drawing portion 31 is configured to cross and arrange the metal wire A41 and the metal wire B42 so that one of the diagonal lines in the rhombic mesh is parallel to the transport direction. On the other hand, in the conveyor 35C, a large number of plate members 35D having a predetermined width are arranged in an endless track shape, and the metal wire A41 and the metal wire B42 are locked to both ends in the longitudinal direction of each plate member 35D so as to reciprocate. In order to route, the distance between the metal lines is reliably maintained at a desired distance. The fixing means 33 is a spot welder having an upper electrode portion 38 and a lower electrode portion 39 that sandwich the crossing portions of the metal wires of the wire crossing 43. The fixing means 33 is configured so that the upper electrode portion 38 can move closer to and away from the fixed lower electrode portion 39. The clamping pressure, current value, and proximity time (time for clamping the metal wire) by the upper electrode part 38 and the lower electrode part 39 can be appropriately selected.

  The net strip 44 manufactured in this way is cut off at both ends 44A in the transport direction. The underline side trolley 35A and the upper line side trolley 35B are continuously folded and supplied at both ends without cutting the metal wire A41 and the metal wire B42. In the case of using a type that supplies a metal wire that has been cut and straightened, it is not necessary to cut off both end portions 44A of the mesh strip 44. A salvage wire 46 is placed on both edges of the wire intersection belt from the salvage wire lead-out portion 45 disposed immediately above both edges, and then above both edges of the wire intersection belt and The crossing portion between the metal wire A41 and the salvage wire 46 and the crossing portion between the metal wire B42 and the salvage wire 46 are welded and fixed by the salvage wire fixing means arranged below. The salvage wire fixing means includes an upper electrode portion 47 and a lower electrode portion 48, and has the same structure as the fixing means 33.

  The net 44 manufactured in this way is wound up by the winding roll 34 together with both ends in the transport direction including the salvage wire. When winding on the take-up roll, a presser 49 is arranged on the salvage wire 46 at each end of the portion where the wire mesh band contacts the take-up roll, and the wire mesh band is taken up while applying the load of the presser. Wind it on a roll. Due to the pressurization by the load of the presser, the weld point between the metal wire A41 and the salvage wire 46 and the salvage wire portion between the weld point between the metal wire B42 and the salvage wire 46 adjacent to the weld point are within the thickness direction of the mesh strip. Bent in the direction. Thus, the net-like body wound up by the take-up roll 34 is used in the manufacturing process of the netted glass plate.

  According to FIG. 11 showing the details of the pressing element, a frustoconical pressing element 49 is placed on the salvage wire 46 at each end edge where the wire mesh band 44 is in contact with the take-up roll 34. The presser rotates with the progress of the wire mesh band 44, and the presser portion of the large diameter portion carries the load of the presser's own weight on the salvage line. The wire mesh band 44 is wound around the winding roll 34 while being applied. Even if the wire mesh band 44 is wound around the winding roll and the diameter of the winding body increases, the pressing element 49 is a frame body whose axial center of the pressing element can move up and down so that the pressing can be continued. (Not shown).

The present invention will be specifically described below.

A rhombus welded wire mesh band with a salvage wire for a meshed glass plate having a shape (the length of the mesh is 500 m and the width of the mesh is 2.8 m).

  As the underline-side trolley 35A and the upper-line side trolley 35B, a type that supplies metal wires that are formed by cutting the metal wires A and B at both ends into straight lines was used. The salvage wire was welded to the metal wires A and B at a position on the inner side in the width direction of about 7.4 mm from the intersection of the metal wires A and B at the edge of the net.

  The presser when winding the net on the take-up roll had a weight of 3 kg, and a frustoconical presser with outer diameters of 10 cm and 6 cm was used so that the portion with the outer diameter of 10 cm was on the outside. The wound wire mesh band was unrolled on a flat surface to a length of about 5 m, and the waviness value was measured. As shown in FIG. 12, the waviness value is defined by the difference h between the height of the wave valley at the edge and the height of the mountain. The period of the wave is defined by the distance L between the peaks of the wave at the edge. The value of undulation was 0 cm (below the lower limit of measurement), and no undulation occurred. The salvage wire had an inward bending value (d in FIG. 3) of 0.1 to 0.4 mm in the thickness direction of the wire mesh, and an average bending value of 0.25 mm.

Comparative Example 1
A wire mesh band with a salvage wire is wound around a winding roll in the same manner as in Example 1 except that the pressing element is not provided in Example 1 above. Thereafter, the wire mesh band was unrolled on a plane in the same manner as in Example 1, and the degree of edge waving was measured. As a result, the waving value was 5 cm and the wave period was 55 to 80 cm. The bend of the salvage wire was 0.1 mm or less.

Example 2
After continuously feeding the rhombus welded wire mesh with the salvage wire obtained in Comparative Example 1 from the winding roll and passing through a pretreatment tank, a plating tank, a washing tank, and a tin plating surface treatment apparatus consisting of a drying furnace in this order, It was made to wind up on a winding roll. When winding on the take-up roll, a cylindrical presser having a weight of 0.5 kg and an outer diameter of 5 cm is placed on the salvage wire at each edge where the wire mesh band contacts the take-up roll. While rotating the child, it is pressed onto the salvage line by the load of the weight of the pressing member. After winding on the take-up roll, the wire roll was unwound and unrolled on a flat surface about 5m in length, and the degree of edge waviness was measured. The wavy value was 0 cm (below the measurement limit). There was no waviness. The salvage wire was bent inward in the thickness direction of the wire mesh by a value of 0.2 to 0.5 mm and an average value of 0.35 mm.

Comparative Example 2
A wire mesh strip with a salvage wire subjected to tin plating is wound around a winding roll in the same manner as in Example 2 except that the pressing member provided on the winding roll in Example 2 is not provided. Thereafter, the wire mesh band was spread on a plane in the same manner as in Example 2 to measure the degree of edge undulation. As a result, the value of undulation was 8 cm and the wave period was about 30 to 75 cm. The bend of the salvage wire was 0.1 mm or less.

Each metal line A and each metal line B are welded to each other at the position of each crossing point in a state where B is crossed to form a square or rhombus mesh, Further, a salvage line is arranged along each edge on both sides in the width direction, and the salvage line is welded to each other at each crossing point with the metal line A and each crossing point with the metal line B. In the method of manufacturing a woven mesh strip for a glass plate, the woven mesh strip After the knitting net or after the surface treatment, when the winding roll is wound, a presser that can be rotated from above the salvage line of the rhomboid strip is wound in the length direction of the salvage line. By continuously pressing in the crossing direction and plastic bending deformation so that the salvage line part between adjacent adjacent weld points bends at the intermediate part, the distance between both adjacent weld points is shortened and wound. The manufacture of a rhomboid strip for a glass plate with a mesh, characterized in that the spacing between adjacent metal lines at the edge of the strip-shaped body after the cutting operation is made closer to the spacing between adjacent metal lines B at the center of the strip-shaped body Method.
