[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel wire fence manufacturing apparatus.

[0002]

2. Description of the Related Art A vertical and horizontal steel wire is welded with a spot welding machine to form a coarse mesh, and the upper end or upper and lower ends thereof are bent to form a fence (fence), or a steel made separately without bending. Recently, steel wire fences, such as those made by welding wire-made cylinders, have become widely used. Since there are only three types of steel wire fence manufacturing work: steel wire cutting, welding assembly, and bending, an ordinary shearing machine,
A general-purpose or multi-point welding machine and a bending press are sufficient, and no special mechanical equipment is required. Instead, it took a lot of manpower.

[0003]

[Problems to be Solved by the Invention] Increase in demand for steel wire fences,
In order to cope with the shortage of manpower, it is conceivable to automate equipment machines that were conventionally used manually. However, it is neither easy nor a good idea to mechanize the work performed by the human eyes, hands, and head. As an exclusive welder manufacturer for various mass-produced products, the applicant introduced the first large-scale exclusive welder for steel wire fence manufacturing, using the accumulated technology, and developed an accurate, inexpensive, and robust steel wire fence manufacturing apparatus.

[0004]

According to a first aspect of the invention for manufacturing a steel wire fence of the present invention, an upper end or upper and lower ends of a steel wire flat reticulated panel is inserted into a side opening of a steel wire tubular beam. A manufacturing device of a steel wire fence welded to a longitudinal steel wire of a beam, wherein a steel wire coil stand in which only the number of vertical steel wires of the steel wire fence is arranged,
A panel production department that welds horizontal steel wires of the width of the fence one after another to a strip-shaped flat net to the vertical steel wires fed out from each of the above stands, and cuts this to the height of the fence and sends it out. Similarly, a horizontal flat wire is welded to the vertical steel wire at a narrower interval,
A beam production unit that cuts to the length obtained by subtracting the width of the side opening from the circumference of the beam, and rounds it into a tubular shape, and the panel that came out of the panel production unit continues to lie down, and the beam is supplied back and forth. In a multi-point welding machine with a mechanism, the front end of the above panel is inserted into the beam from one supply mechanism to the welding position for welding, and the rear end of the panel is inserted into the beam from the other supply mechanism and welded. It is characterized in that it is provided with an assembling unit configured to do so.

Similarly, in the second aspect of the invention, a steel wire fence is manufactured in which the upper end or upper and lower ends of a steel wire flat-meshed panel is inserted into the side surface opening of the steel wire tubular beam and welded to the longitudinal steel wire of the beam. In the device, the beam has a large number of steel wire notch rings connected by five horizontal steel wires, and the two horizontal steel wires form a side opening together with the notches of the respective wheels. Yes, the beam supply mechanism for the panel that moves horizontally between the upper and lower electrodes of the multi-point welding machine, the four horizontal steel wires excluding one side opening of the beam are loosely sandwiched from above and below each wire. It consists of an inclined guide material that slides down in the direction perpendicular to and a positioning mechanism that clamps both ends of the beam at the lower end of the guide material and reaches the welding position as it is. The inclination angle of the guide is set so that the parts are almost horizontal. And wherein the are because

[0006] Similarly, in the third invention, in the second invention, the horizontal steel wire on the side opposite to the side opening of the beam attached to the welding position is stopped slightly above the opening. When the tip of the vertical steel wire at the panel end enters through the opening and stops at a fixed position on the lower electrode of the welding machine, it receives the opposite horizontal steel wire that is pushed down by the upper electrode and accepts this vertical wire. It is characterized in that it is provided with a grooved guide member which is guided onto the tip of the steel wire.

[0007]

The object of the present invention is that the panel in which vertical and horizontal steel wires are made into a coarse mesh by welding becomes the main body of the fence, and a large number of steel wire notch rings are connected to the ends of the panel by horizontal steel wires. It is a steel wire fence with a beam. The notch parts of the notch ring are aligned in the same direction, and horizontal steel wires are welded on both sides to form side opening parts of the beam. It is a product in which the tip of the vertical steel wire at the panel end enters the beam through the side opening and is lap-welded to the horizontal steel wire on the opposite side.

In the steel wire fence manufacturing apparatus of the first invention, steel wires are simultaneously fed from as many steel wire coil stands as the number of vertical steel wires of the fence which is the target product, and the width of the fence is extended to these. The horizontal steel wires cut into pieces are welded one after another to form a band-shaped flat net, but the intervals between the horizontal steel wires are different between the panel manufacturing section and the beam manufacturing section. The panel has a horizontal steel wire interval suitable for the main body of the fence, but when the beam is rolled into a tubular shape, at least three horizontal steel wires must pass through the beam, resulting in a narrower interval.

Since the steel wire fed out from the coil stand becomes the vertical steel wire of the fence, all of them are put in a multi-point welding machine in an aligned manner, and after horizontal steel wires are lap welded, they are withdrawn one after another and sent to a shearing machine. Divide it into lengths, and if it is the panel production department, proceed to that point and send it to the assembly part with the beam, and if it is the beam production department, roll it into a cylinder with a bending press. The panel that exits the panel manufacturing section continues to lie down and advances, passing through between the upper and lower electrodes of the multi-point welder in the assembly section, but with a supply mechanism that sends the beam to the welding position on both the front and rear sides of the welder. ing.

Since the first beam is sent from one of the feeding mechanisms and the side opening is directed rearward, the front end of the panel is inserted therein and welded to the horizontal steel wire of the beam. When the welding is complete and the panel has passed the welding equipment of the assembly, one beam from the other supply mechanism is brought into the welding position. Since the side opening is directed forward, the panel is moved backward and the rear end is inserted into the opening and welded to the horizontal steel wire of the beam. This completes the steel wire fence with beams on both ends of the panel. If the beam is attached only to the top of the fence, the supply mechanism is sufficient on one side.

In the second invention, one horizontal steel wire of the beam is provided on each side of the side opening, and one horizontal steel wire which is on the opposite side of the beam is overlap-welded to the vertical steel wire end of the panel. And a beam equipped with a total of five wires, one each passing through the intermediate position between the steel wire and the opening, and using the steel wire arrangement to slide the beam down to the welding position. Keeps the beam attitude of.

That is, the other four horizontal steel wires except one of the two horizontal steel wires at the side opening of the beam are parallel to each other at the four corners of the quadrangle. It can be fed without changing its posture by gently sandwiching it with an inclined guide material and sliding it down in a right angle direction. Therefore, the inclination angle of the glide surface of the inclined guide member is adjusted so that the side opening of the beam is oriented horizontally during the descent. After sliding down to near the welding position, the beam is attached to the welding position by sandwiching both ends with the mechanical positioning mechanism and attaching it to the welding position. Accept the horizontal panel edge as it is.

In a third aspect of the present invention, a horizontal steel wire opposite to the side opening of the beam placed in the welding position in the second invention, that is, a horizontal steel wire to be welded to the panel vertical steel wire enters from the side opening. The end of the vertical steel wire of the panel is not disturbed, and the horizontal steel wire is properly overlapped and welded on the front end of the vertical steel wire of the panel during welding. That is, since the horizontal steel wire of the beam attached to the welding position is located slightly above the side opening, it does not hinder the entry of the vertical steel wire of the panel and is pushed down by the upper electrode during welding. , The horizontal steel wire enters the groove of the grooved guide member and is correctly overlaid on the vertical steel wire tip.

[0014]

1 and 2 show an example of a steel wire fence made by the device of the present invention. The steel wire flat reticulated panel 1 has a normal height as a residential fence (fence), and the middle thereof is omitted in the drawings. The upper and lower ends of the panel 1 enter the side opening 3 of the steel wire tubular beam 2 and are welded to the longitudinal (transverse) steel wire 2b of the beam 2 to form a weld W.

The panel 1 has a horizontal steel wire 1b which is perpendicular to the vertical steel wire 1a.
The beam 2 is formed by welding five horizontal steel wires 2b at a right angle to the notched ring 2a having a rounded vertical line. Two of the five are attached to both sides of the cutout portion of the cutout ring 2a to form the side opening 3. The height of the panel 1, that is, the height of the steel wire fence varies in several types within the range of 0.9 to 1.5 m, but the outer diameter of the beam 2 is 5 in this embodiment.
It is constant at 5 mm. The width is all about 1.8 m. The same device can be used to attach the beam 2 only to the panel 1 not to the upper and lower sides of the panel 1.

FIG. 3 is an overall plan view of an embodiment of the device of the present invention. The beam producing section B and its steel wire coil stand group C are on the upper side, and the panel producing section P and its coil stand group C are on the lower side.
Are arranged. The assembly section A follows to the left of the panel production section P. Each coil stand group C can be made up of a steel wire fence with a width of 1.8 m and a maximum of 40 vertical steel wires 1a,
It is equipped with 40 stands S. All the steel wires drawn from them are aligned in a horizontal line, straightened by a straightening machine D, and sent to each lower electrode of the multi-point welding machine 10. The multi-point welding machine 10 is almost the same for both the beam production section B and the panel production section P. With the horizontal steel wire feeder 10a attached to each,
Weld horizontal steel wires 2b and 1b according to the width of the fence. Up to this point, the detailed description is omitted because it is similar to the well-known technique in welding wire mesh production.

The steel wires that have entered the welding machine 10 side by side come out in the form of a band-shaped flat net.
In the beam producing section B, the notch ring 2a shown in FIG. 2 is cut into a linearly extended dimension, and then the press forming machine 12 rolls it into the required beam 2. The strip-shaped flat net of the panel manufacturing section P is cut by the cutting machine 11 to form the panel 1 shown in FIGS. For both beams and panels, when welding the horizontal steel wire 2b or 1b with the welding machine 10, a cutting allowance (white) is provided before or after the dimension of the notch ring 2a shown in FIG. Need to add. FIG. 4 shows a state in which the cutting machine 11 of the beam manufacturing section B divides the strip-shaped flat net into the dimension material 2 ′ in which the beam 2 is extended one after another. The cutting margin a is the thickness of the upper blade of the cutting machine 11. Since the forming press for rolling the material 2'is a conventional technique, its explanation is omitted.

The panel 1 produced in the panel production section P immediately enters the assembly section a and advances to the bed, and goes to between the upper and lower electrodes of the multi-point welding machine 13 for assembly. As shown in FIGS.
a, 14 and a large number of beams 2 produced by the beam production section B are aligned in each. Before the tip of the panel 1 reaches between the upper and lower electrodes of the welding machine 13, the beam 2 from the beam supply mechanism 14 on the rear side is attached to the welding position. The front end of the panel 1 (the tip of the vertical mesh wire 1a) enters the beam 2 and is welded to the horizontal steel wire 2b of the beam 2 by the upper and lower electrodes (details will be described later).

When the panel 1 having the front end welded with the beam 2 passes through the welding machine 13 and stops, the beam 2 is sent from the front beam supply mechanism 14a to the welding position. Then, the panel 1 is moved backward and the rear end thereof is inserted into the beam and welded. The beam 2 sent from the beam supply mechanism 14 on the rear side has its side surface openings 3 directed rearward, and the beam 2 from the front supply mechanism 14a is directed forward, which will also be described later. In addition, 15 on the left end of FIG. 3 is a product carrier, 16 is a stacking platform, and 1 of FIG.
7 is a feeder. The fact that the arrows indicating the panel traveling direction in FIG. 5 and FIG. 6 are opposite is due to the concept drawing for the former and the manufacturing drawing for the latter, but FIG. 6 is a view of FIG. 5 from the back side.

Next, an embodiment of the second invention will be described with reference to FIGS. As shown in Figs. 1 and 2, the target steel wire fences are the vertical steel wire 1a and the vertical mesh of the flat reticulated panel 1 on the beam 2 in which approximately the same number of notch rings 2a are connected by five horizontal steel wires 2b. The upper and lower ends of the steel wire 1a are inserted and welded, and the two horizontal steel wires 2b of the beam 2 are welded near the notch of the notch ring 2a to form the side opening 3. There is.

Such a beam 2 is difficult even by automatically feeding it, but when feeding it to the multi-point welding machine 13 for assembly, the front and rear ends of the panel 1 which can be moved horizontally can be inserted. , The side openings 3 must be placed in the welding position first backwards and then forwards. A second invention that solves this problem is an assembly unit A shown in FIG.
It is applied to the beam supply mechanisms 14a, 14 before and after the welding machine 13. The beam supply mechanism 14a also shown in FIGS.
Since 14 is symmetrical, only the rear side mechanism 14 will be described with reference to FIGS.

As shown in FIG. 6, the beam supply mechanism 14 has an open upper surface, and a chain conveyor 4 with a receiving plate 4a as shown at the left end of FIG. We will proceed to one by one. Although the steel wire beam 2 as shown in FIGS. 1 and 2 has a shape that is difficult to carry by the conveyor, the chain conveyor 4 of this embodiment, as shown in FIG. 7, connects the horizontal steel wire 2b of the beam to the shoulder of the link plate 4b. The notch ring 4a is restrained from moving back and forth by the receiving plate 4a placed on the top of the link plate 4a and set up at the center of the link plate 4a. Further, one horizontal steel wire 2b of the beam placed on the shoulder of the link plate 4b is one horizontal steel wire 2b on one side of the side opening 3, and the other one is the other adjacent horizontal steel wire 2b on the conveyor 4. All the beams 2 are mounted so that they are carried in the same posture. This embodiment uses beam 2
Is manually placed on the conveyor 4, but it may be automatically sent from the beam forming section B and placed on the conveyor 4.

The beams 2 lined up on the upper surface conveyor 4 of the beam supply mechanism 14 as shown in FIG. 6 transfer to the inclined guide member 5 one after another at the end of the conveyor 4 as shown in FIG. The inclined guide member 5 is a structure in which four horizontal steel wires 2b of the beam 2 are lightly sandwiched between upper and lower parallel plates and gravity slides down. At the place where the conveyor 4 moves to the inclined guide member 5, the pick-up bar 6 attached to the guide member 5 welcomes the beam 2 so as not to float. Shutters 7 are provided at three positions along the inclined guide member 5, and stoppers 8 are attached to the lower ends. The stop plate 7a of the shutter 7 and the stop bar 8a of the stopper 8 normally close the runway of the inclined guide member 5, and when one beam 2 goes out to the welding position S, the stopper 8 first opens and closes. ,
Next, the shutter 7 is sequentially opened and closed from the bottom to replenish the beam 2.

The beam 2, which has been stopped in the correct posture from above and below by the stoppers 8 and 8, has its both ends clamped by the clamping portion 9a with the fluid pressure cylinder of the positioning mechanism 9 shown in FIGS. From the lower end of the inclined guide member 5, the upper and lower electrodes 13a, 13b of the multi-point welding machine 13 for assembly
The welding position S can be reached. Beam 2 at welding position S
Since it is in such a posture that it is sandwiched by the lower end of the inclined guide member 5, its side surface opening 3 is oriented almost in the horizontal direction. This is because the inclination angle θ of the inclined guide member 5 is designed so that the side opening 3 of the beam 2 in the downhill posture is oriented horizontally, and the angle θ in this embodiment is 45 °.

In FIG. 8, the upper electrode 13a of FIG. 7 is lowered and the tip of the vertical steel wire 1a of the panel 1 and the horizontal steel wire 2b of the beam 2 are overlapped and welded by a chain line. The movement of the panel presser 17 with the fluid pressure cylinder 17a to be fixed is also shown. 18 is a cradle. The beam 2 attached to the welding position in FIG. 8 may have the side opening 3 into which the tip of the panel 1 is inserted oriented horizontally, but the beam transverse steel wire 2b to be welded on the opposite side is As shown in the figure, if the panel vertical steel wire 1a is right above the panel from the beginning, the tip may be caught and do not overlap when the panel vertical steel wire 1b enters. Therefore, the tip of the panel 1 can be easily received by slightly changing the inclination angle θ of the inclined guide member 5 or slightly changing the relative position of the horizontal steel wire 2b of the beam 2 itself from the design stage. However, in that case, since the horizontal steel wire 2b pushed down by the upper electrode 13a is separated upward, there is a possibility that the vertical steel wire 1a is not always accurately placed at the fixed position of the tip of the vertical steel wire 1a.

The third invention solves the above problems,
An example thereof will be described with reference to FIG. This embodiment uses beam 2
As a means for placing the horizontal steel wire 2b on the opposite side of the side opening 3 on the upper side away from the entry position of the panel vertical steel wire 1a as shown in the figure, the inclination angle of the inclined guide member 5 and the horizontal steel of the beam I am not changing the line layout. That is, when the beam 2 is sandwiched by the sandwiching portion 9a of the positioning mechanism 9 and is attached to the welding position S, the horizontal steel wire support bases 19 and 1 at the two positions shown in FIG.
9 causes the beam 2 to rotate slightly around the sandwiching portion 9a. Since the rotation angle is slight, the beam lateral steel wire 2b to be welded moves upward without hindering the panel entry from the side opening 3. As shown in FIG. 9, the holding portion 9a has a protruding portion that is inserted into the inside of the beam 2 and is lightly held by the fluid pressure cylinder 9C behind it.
It does not prevent the beam 2 from rotating a little when arriving at.

Incidentally, the central one of the three support bases 19 in FIG. 10, that is, the support base 19 for supporting the horizontal steel wire 2b on the opposite side of the side opening 3 is supported by the spring 19a, and therefore the upper electrode 13a. When the welding pressure is applied to the horizontal steel wire 2b, the horizontal steel wire 2b crushes the support 19 and moves down, and is welded to the tip of the panel vertical steel wire 1a in an overlapping manner. At that time, the horizontal steel wire 2b enters the groove 20a of the grooved guide member 20, is guided to the tip of the vertical steel wire 1a, and is welded to the correct position. At that time, the beam 2 slightly rotates around the holding portion 9a. When the beam 2 is welded to the rear end of the panel 1, the three support bases 19 on the right end support the lower horizontal steel wire 2b of the opening 3 of the beam 2 in the direction opposite to that of FIG.

Although one embodiment has been described above, it is needless to say that the present invention can be changed and applied by a technique known to those skilled in the art without changing the gist thereof. For example, the number, arrangement, welding position, etc. of the horizontal steel wires 2b of the beam 2 are not limited to those in the above-mentioned embodiment, but a part of the entire equipment shown in FIG.
It is up to the implementor to change or omit.

EFFECTS OF THE INVENTION The present invention has completed, as a steel wire fence manufacturing apparatus, for the first time a fully-automated dedicated welding facility for mass production. The steel wire fence manufacturing apparatus of the present invention has opened a mass production method in which a band-shaped flat net is first formed as a manufacturing unit for a steel wire tubular beam, and the flat wire net is divided and rounded. Then, the panel manufacturing section was connected to the assembly section, and the beam supply mechanism was attached to the front and rear of the multi-point welding machine in the assembly section, so the panel just made immediately advanced between the upper and lower electrodes of the welding machine, and one of the supply mechanisms Since the beam is welded to one end of the panel and the beam of the other supply mechanism is welded to the other end of the panel, the troublesome work of inserting the panel end into the side opening of each beam and welding is completely completed. It was automated and was able to achieve both precision and efficiency. Regarding the welded part of the panel and beam, in the conventional individual welding, one panel vertical steel wire is welded to both the horizontal steel wire along the side opening of the beam and the opposite horizontal steel wire, especially along the opening. Although it was difficult to weld it to the horizontal steel wire, it was proved that the welded portion showed sufficient strength at one place by the high quality welding by the multi-point welding machine and the beam supply mechanism of the present invention.

In the second aspect of the invention, when one end of the panel, which lays flat and moves horizontally, advances between the upper and lower electrodes of the multi-point welding machine for assembly, the side opening is oriented substantially horizontally so as to accept it. We have developed a beam supply mechanism that can continuously and automatically supply cylindrical beams. That is, by setting the inclination angle of the inclined guide member that gently sandwiches the four beams except the one of the side opening of the beam with five horizontal steel wires from the top and bottom so that the side opening is oriented in the horizontal direction, Since both feeding and posture control are performed and both ends are clamped and positioned at the welding position in that posture, one end of the panel can be welcomed. The third invention is to make the second invention more reliable, and when the beam is attached to the welding position, the beam horizontal steel wire to be welded is pulled up to a position that does not interfere with the tip of the vertical steel wire of the panel to enter. When pushed down by the upper electrode, the horizontal steel wire is put in the groove of the grooved guide material so that it is surely overlapped on the tip of the vertical steel wire of the panel, so operating accidents are avoided and the welding position is uneven. Could be prevented.
