Reference numeral 41 is a heat insulating plate inserted between the flat nets 32a and 32b, and 42a and 42b are feed rollers of the heat insulating plate 41.

In the production of a three-dimensional wire net by the production apparatus configured as described above, the flat nets 32a and 32b along the guide devices 31a and 31b are intermittently transferred. When the flat nets 32a and 32b are stopped, the feeding device 3
Since 5a and 35b pass the tip portions of the web wire rods 34a and 34b through the flat net 32a and feed them to the flat net 32b, the web wire rods 34a and 34b
The welding machine 37 welds the tip of the to the flat screen 32b. The cutter 36 cuts the web wire rods 34a and 34b whose ends are welded to the flat net 32b. At this time, depending on the thickness of the cutter 36,
The protruding portions 40 of the web wire rods 34a and 34b protruding from the flat net 32a are formed.

As described above, in the flat nets 32a, 32b that are intermittently advanced at the same time, when the web wire rods 34a, 34b whose ends are welded and cut to the flat net 32b reach the welding machine 38, the web wire rods 34a, 34b. The welder 38 welds the end of the
The web wire rods 34a, 34b connect the 32a, 32b to each other.

Further, when the flat nets 32a, 32b progress intermittently and the respective web wire rods 34a, 34b reach the trimming shear 39, the web wire rods 3

When interposing the heat insulating plate 41 between the flat nets 32a and 32b, the heat insulating plate 41 is fed to the supply passage 33 between the guide devices 31a and 31b.
It is supplied by 2a, 42b and is intermittently transferred together with the flat nets 32a, 32b.

{Problems to be Solved by the Invention} The conventional method and apparatus for manufacturing a three-dimensional wire mesh are
Flat meshes 32a, 3 along the guide devices 31a, 31b provided at intervals.
By transferring 2b, the flat nets 32a and 32b are maintained at the same intervals as the preset intervals. When the heat insulating plate 41 is interposed between the flat nets 32a and 32b, the heat insulating plate 41 is fed into the supply passage 33 formed between the guide devices 31a and 31b.

Therefore, it is necessary to provide the guide devices 31a and 31b, and the size of the supply passage 33 is determined according to the thickness of each of the guide devices 31a and 31b. There is a problem that the maximum thickness of the heat insulating plate 41 that can be used is restricted. It is also necessary to advance the heat insulating plate 41 by the feed rollers 42a and 42b separately from the flat nets 32a and 32b.

Then, as described above, the web wire rods 34a, 34b whose ends are welded to the flat nets 32a are cut by the cutter 36 while being transported to the flat nets 32a, 32b at preset intervals.
Therefore, the cutter 36 can only be moved along the surface of the flat net 32a, and the flat net 32a hinders the cutting of the web wire rods 34a, 34b by the cutter 36. Therefore, it is impossible to cut the web wire rods 34a, 34b along the surface of the flat net 32a, corresponding to the thickness of the cutter 36, the web wire rod 34a protruding to the front surface side of the flat net 32a, 34b
The protrusion 40 is generated. Therefore, the web wire 34a,
After welding 34b to the flat net 32a, a trimming shear 39 for cutting the protrusion 40 is provided, and it is necessary to cut the protrusion 40, and the waste of the web wire rods 34a, 34b becomes large. There's a problem.

The present invention is to solve the above problems,
Corresponding to the distance between the pair of flat nets, it is possible to interpose a porous plate for the purpose of heat insulation or the like between them, and in the case of interposing the porous plate, A three-dimensional wire mesh that does not require a transfer means of only a perforated plate and enables the wire connecting the pair of flat nets to be cut to a required length, so that the wire can be used efficiently. An object of the present invention is to obtain a manufacturing method and a manufacturing apparatus therefor.

{Means for Solving the Problems} A method for manufacturing a three-dimensional wire netting according to the present invention is such that a pair of flat meshes that are parallel to each other are maintained at an interval smaller than a preset interval for the pair of flat nets. Then, it is arranged on the transfer line so as to be slidable in the direction parallel to the surface of the flat screen, and the pair of flat screens are transferred intermittently at the same time, and with respect to each of the intermittent feeds, with respect to the transfer direction of the flat screen. A splicing wire may be intermittently supplied in the intersecting direction, the first welding end portion of the splicing wire end may be welded to the flat mesh on the supply direction side, and then the pair of flat meshes may maintain the preset interval. The wire is cut to a possible length, and the second welded end, which is the end opposite to the first welded end of the cut wire, is pushed in a direction in which a pair of flat nets are arranged, Move the welded wire mesh in the direction away from the other wire mesh and The second welding end is brought close to the opposite flat mesh, and the second flat wire
It is characterized in that the welded ends are welded to each other so that the distance between the pair of flat screens is set to the above-mentioned set interval, and the respective flat screens are connected by a connecting wire.

The pair of flat meshes that are parallel to each other are used as a means for maintaining an interval smaller than a preset distance between the pair of flat meshes on both sides of a perforated plate that is thinner than the preset distance between the pair of flat meshes. It is also possible to superimpose each flat net on the surface and to intermittently transfer them at the same time.

In addition, depending on the use of the three-dimensional wire mesh, it is possible to close and close the mesh of the flat mesh by stacking and fixing an iron plate on almost the entire surface of either one of the pair of flat meshes. Is.

Further, the feeding direction of the connecting wire to the flat screen may be substantially vertical to the flat screen or may be inclined to the flat screen. Therefore, after the first welded end is welded to one of the flat screens, the length of the connection line cut into a required length is as follows:
If the wire length is almost corresponding to the interval set in advance for a pair of flat screens and the connecting line is inclined with respect to the flat screen,
Corresponding to the inclination angle, the distance becomes longer than the preset distance between the pair of flat screens.

The three-dimensional wire mesh manufacturing apparatus of the present invention is arranged such that a pair of flat meshes which are parallel to each other are maintained at a distance smaller than a preset distance between the pair of flat meshes and are parallel to the surface of the mesh. A transfer line for transferring in a direction, and an intermittent transfer means for intermittently transferring the pair of flat nets along the transfer line, corresponding to the intermittent transfer of the pair of flat nets by the intermittent transfer means, Intermittent wire supply means for intermittently supplying a wire in a direction intersecting the transport direction of the wire net, and bringing the first welding end portion of the wire end close to the wire net on the supply direction side, the wire intermittent wire. First welding means for welding the first welding end portion of the joint wire supplied by the supplying means to the flat mesh on the supply direction side, and the joint for welding the first welding end portion to the flat mesh by the first welding means. Lines can be maintained on the pair of flat screens at preset intervals. Cutting means for cutting into an effective length, at a position apart from the cutting means, a second welding end portion which is an end portion on the side opposite to the first welding end portion of the splice wire, in a direction in which a pair of flat nets are arranged. To move the welded wire mesh in a direction away from the other wire mesh, and bring the second welding end close to the wire mesh opposite to the moving direction. Second welding means for welding the second welding end portion to the adjacent flat mesh are arranged along the transfer line.

The pair of flat meshes that are parallel to each other are used as a means for maintaining an interval smaller than a preset distance between the pair of flat meshes, on both sides of a perforated plate that is thinner than the preset distance between the pair of flat meshes. It is also possible to superimpose each flat mesh on the surface and transfer them intermittently at the same time.

{Operation} The method and apparatus for manufacturing a three-dimensional wire netting according to the present invention cause a pair of flat nets that are parallel to each other to maintain an interval smaller than a preset interval for the pair of flat nets. For example, the pair of flat nets are stacked on both side surfaces of a perforated plate for the purpose of heat insulation, which is appropriately thinner than the set interval. The pair of flat nets and the perforated plate are arranged in a transfer line, and they are simultaneously and intermittently transferred by an intermittent transfer means, and the intermittent wire intermittent supply means responds to the intermittent transfer by a pair of flat wires. The wire is intermittently supplied, and the first welding end portion of the connection wire tip is brought close to the flat mesh on the supply direction side. The first welding means welds the first welding end portion close to the flat screen to the flat screen. Next, the cutting means cuts the joining wire to which the first welding end portion is welded to a length that allows the distance between the pair of flat nets to be the preset distance.

When the wire cut by the cutting means reaches the interval setting means by the transfer of each flat mesh, the space setting means pushes the second welding end portion of the wire, and the flat wire having the first welding end welded, The wire is moved in a direction away from the other wire mesh, and the second weld end is brought close to the wire mesh opposite to the moving direction. With this movement of the tie wire, the distance between the pair of wire nets becomes a predetermined distance therebetween, so that the second welding means welds the second welding end of the wire tie to the wire mesh adjacent to it. Then, a three-dimensional wire net is manufactured.

When the perforated plate is not needed, instead of the perforated plate, a jig such as a similar plate is fixedly arranged, and a pair of flat nets are slid along the jig to perform the same operation as described above. Manufacture a three-dimensional wire mesh connected by connecting wires at required intervals.

As described above, after the pair of flat screens is welded with the first welding end portion to one of the flat screens during the intermittent transfer while maintaining the interval smaller than the preset interval, The splicing wire is cut into a length that allows the pair of flat screens to have a predetermined spacing therebetween. That is, since the wire is cut by the cutting means at a position distant from the surface of the flat wire, the flat wire does not hinder the cutting of the wire by this cutting means. It is possible to disconnect.

Moreover, as described above, the second welding end portion side of the connection wire that is accurately cut to the required length is pushed by the gap setting means to bring the second welding end portion close to the flat mesh, and to the flat mesh. Since the second welded end is welded, it is possible to prevent the end of the wire from significantly protruding from the wire mesh when the second welded end of the wire is welded to the wire mesh.

Further, since a pair of flat nets are first transferred intermittently while maintaining an interval smaller than a preset interval between them, when inserting a perforated plate such as heat insulation inside the three-dimensional wire net, the perforated plate It is not necessary to stack a pair of flat nets on both sides and intermittently transfer the perforated plate together with the flat net, or the transfer means dedicated to the perforated plate is unnecessary.

Therefore, when inserting a heat insulating or other perforated plate into the three-dimensional wire net, by transferring each flat net on both sides of the perforated plate at the same time,
It is possible to manufacture a three-dimensional wire netting in which the perforated plate is inserted. Further, the perforated plate can be transferred at the same time by the transfer of each flat net, and since the transfer means dedicated to the perforated plate is not required, the cost can be reduced and the perforated plate can be of almost any thickness. It is possible to use perforated plates.

Supplying a connecting wire to the pair of flat nets that are intermittently transferred,
After the first welding end portion of the joining wire is welded to the wire netting on the supply direction side by the first welding means, the distance between the pair of wire nets can be set to a preset distance. Then, the connecting wire is cut by a cutting means. Therefore, the position of the wire distant from the wire mesh is determined according to the dimensional difference between the distance between the wire wire and the distance between the wire mesh when the wire is welded to the wire mesh and the distance set in advance between the wire mesh. Since the cutting means cuts, the flat mesh does not hinder the cutting of the wire by the cutting means, and the wire can be accurately cut to a required length by the cutting means.

Then, as described above, the first welding end is welded to the flat mesh,
And, the second welding end portion of the wire cut to a required length is pushed by the spacing setting means to move the flat net to which the first welding end portion is welded, and the second welding end portion to the other flat net. Are made to be close to each other, and the pair of flat nets are set to have a predetermined spacing therebetween, and the second welding end portion thereof is welded to the flat net by the second welding means.

Therefore, since it is possible to perform welding with the second weld end of the splicing wire substantially aligned with the surface of the flat mesh, the end of the splicing wire protruding from the flat mesh is trimmed as in the conventional example. There is no need for labor and it is possible to use the connecting wire efficiently. Also, a three-dimensional wire mesh having an arbitrary thickness can be manufactured by cutting a joining wire in which the first welding end is welded to the wire mesh to a length corresponding to the interval set for the pair of wire mesh. Is.
