[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cutting a glass plate with a net / wire material, which is capable of forming a good cut end surface to improve the product yield when cutting the front end side of the glass plate with a net / wire material. And equipment.

[0002]

2. Description of the Related Art Among flat glass, in addition to normal type flat glass, there is a flat glass with a net / wire material in which a wire mesh or metal wire is inserted in the center layer to reduce scattering and falling of fragments even if it breaks due to impact. Flat glass with nets and wire rods is widely used for windows of houses, buildings, schools, shops, fences of stairs, etc. It is also used for the openings, roofs and arcades of buildings that are obligatory.

At the production site of the above-mentioned plate / glass containing net / wire material, when the tip end of the plate / glass containing net / wire material that is continuously sent out in the form of a band is cut as a cut-out portion, Unlike the case, not only cutting the glass portion is necessary, but also the wire netting and the metal wire must be broken at the same time. Therefore, various cutting devices have been proposed so far.

FIG. 3 shows, among the above-mentioned conventional devices, Japanese Examined Patent Publication Sho 53.
25 shows a cutting process in the case of using a net glass-containing plate glass cutting device, which has been published as an application of No. 25326.

According to the drawing, the cutting step is a step of engraving the cutting groove 3 in the plate glass 1 containing the net material 2 and dividing the cutting into the main body portion 4 side and the cutting portion 5 side. (A) and the cutout portion 5 defined by the cutting groove 3
The step of dividing the plate glass 1 (b) which is pushed down from the engraving side along with the step (b), and the cutout part 5 connected to the main body part 4 side through the net material 2 remaining after the plate glass 1 is divided is lifted. The lifting step (C) and the breaking step (D) of breaking the net material 2 by pulling the cut-out portion 5 after lifting in the counterclockwise direction are sequentially performed.

[0006]

By using the above-mentioned conventional apparatus, it is possible to carry out the cutting work of the plate glass with the netting material while realizing labor saving.

However, in the case of the conventional apparatus, the process is not so different from that performed manually, and it is necessary to swing the cutout portion 5 up and down in order to break the net material. There is a possibility that the cut end surfaces 4a and 5a may be damaged by being in contact with each other at the time of movement, and that the fracture shape of the net material may be deformed.

[0008]

The present invention has been made in view of the above problems found in the prior art.
A structural feature of the cutting method according to claim 1 is that a cutting groove is formed in a width direction intersecting a feeding tip side of a plate / glass containing a net / wire to cross a feeding direction, and a cutting groove is formed on a main body side and a cutout side. A cutting groove engraving step for partitioning, a plate glass breaking step for breaking the cutout portion defined by the cutting groove from the engraving side of the cutting groove along the cutting side, and the main body side via a net / wire material The chuck holding process in which the cut-out portion after breaking that is connected to the chuck is repositioned and held in the chuck, and the cut-out portion held by the chuck is cantilevered with a fulcrum near the main body, It consists of a net / wire breaking step in which the wire / wire is pulled and ruptured by rapidly feeding the cutout portion in the direction of feeding the sheet-containing glass.

The cutting device according to a second aspect of the present invention is characterized in that the cutting device has a high-speed horizontal feed mechanism fixedly arranged on a support, and is connected to the high-speed horizontal feed mechanism to be freely driven in the horizontal direction. A horizontally movable member to be disposed, a supporting arm member vertically provided on the horizontally movable member, and a cantilevered shaft supported by the supporting arm member. A swing member having a chuck for holding the cut-out side of a plate / glass plate with a net / wire cut off from it, and an axis fulcrum of the swing member interposed between the swing member and the horizontal movable member. It is composed of a drive mechanism that freely controls the swinging in the vertical direction by using as a fulcrum.

[0010]

[Function] Therefore, for plate glass with nets / wires that are continuously fed horizontally, after engraving a cutting groove that divides the main body side and the cutout side, the cutout side is pushed down to cut. By applying stress so as to grow vertical cracks from the groove side, it is possible to break the cutout portion from the main body portion side while leaving the nets / wires connecting to each other.

Under such a condition, after the cutout portion is bent from the body portion side, the cutout portion side is held by a chuck, and a fulcrum is raised near the body portion, and at the same time, in the horizontal direction. By rapidly projecting, the residual mesh / wire material interposed between the main body portion and the cutout portion can be reliably broken under a strong tensile force.

Therefore, the net / wire remaining after connecting the main body portion and the cutout portion after splitting should be broken without contacting the cut end face of the cutout portion with the side of the cut end surface of the main body portion. As a result, it is possible to form a good quality cut end face without damaging the cut end face side, improve the product yield, and also improve the strength of the material used as a net or wire. The cullet powder is prevented from being generated by eliminating the damage on the cut end face side, and it is possible to have a wider selection range.Trouble such as damage to the glass surface that is likely to occur secondarily by the cullet powder. Can be wiped out.

The tip portion 30 of 29 is the support shaft 3
It is arranged while being pivotally supported by 1 so as to be freely linked to the swing member 21 in the swing direction.

Next, the cutting method according to the present invention, which is carried out by using the apparatus of the present invention constructed as described above, will be described together with its operation with reference to the explanatory view showing the working steps shown in FIG.

Continuously fed horizontally at a speed of 200 to 400 m / H, for example, a thickness of 6 to 10 mm and a width of 1.
The mesh / wire rod-containing plate glass 35 of 5 to 3.0 m and the invented device have a positional relationship as shown in FIG. 1. Under such a positional relationship, the delivery tip side of the mesh / wire rod-containing plate glass 35 is A cutting groove 37 is formed on the upper surface in the width direction intersecting the delivery direction.
First, the net / wire-containing plate glass 35 is divided into the main body portion 38 side and the cutout portion 39 side (cutting groove engraving step).

Next, the cut-out portion 39 defined by the cutting groove 37 is pushed down from the engraved side of the cutting groove 37 along with it, and vertical cracks are applied to the plate / glass 35 with net / wire material from the cutting groove 37 side. By applying a stress to grow the wire, the cutout portion 39 is broken from the side of the main body portion 38 as shown in FIG. Process).

After the cut-out portion 39 is folded from the main body portion 38 side in this manner, the cut-out cut-out portion 39 connected to the main body portion 38 side through the net / wire 36 is returned to the original horizontal position. Then, the cut-out portion 39 that has been repositioned is adsorbed by using the chuck 25 provided on the swinging member 21, and is held as shown in FIG. 2B (chuck holding). Process).

After the cutout 39 is held on the swing member 21 side by using the chuck 25, the swing member 21 is pivotally supported on the support arm member 18 side via the support shaft 23. ,
That is, while the fulcrum (axial fulcrum) is formed at an upper position in the vicinity of the cut end surface 38a of the main body 38 in the net glass / wired glass 35, the cylinder 27, which is the drive mechanism 26, is driven and controlled in the direction in which the rod 29 is retracted. Then, the swinging member 21 is pulled up in a cantilever manner, and the cutout portion 39 held via the chuck 25 also follows the cutout portion 39, and the internal angle θ is approximately equal to that shown in FIGS. At the same time as being pulled up within the range of 20 to 25 degrees, the rapid horizontal feed mechanism 1
1 starts its operation, and the rod 13 of the cylinder 12 moves horizontally for a predetermined distance, for example, 400
It moves forward about 0.7 to 3 m at a high speed of up to 1,000 m / H, and the horizontal movable member 15 connected to it also follows the high speed movement in the horizontal direction, so it is pulled up. A sudden moving force in the horizontal direction is applied to the oscillating member 21 that is being generated, and these forces are combined so that the cutout portion 39 held by the oscillating member 21 via the chuck 25 is also obliquely upward. As a result, the net / wire 36 remaining between the main body 38 and the cutout 39 is subjected to a tensile force of 50 to 200 kg / mm ² so that the net / wire 36 can be torn off. ) Will be broken (net / wire rod breaking step).

Since the method of the present invention is carried out through such a series of steps, the net / wire 36 remaining after connecting the main body portion 38 and the cutout portion 39 after the splitting is connected to the main body portion 38. The cut end face 3 of the cutout portion 39 is provided on the cut end face 38a side.
Since 9a can be broken without contacting it,
The cutting end faces 38a, 39a can be formed with good quality without damage to the cutting end faces 38a, 39a, and the product yield can be improved.

Moreover, the breakage of the net / wire material 36 remaining after connecting the main body portion 38 and the cutout portion 39 after breaking is
Since it can be performed by applying a large tensile force of 50 to 200 kg / mm ^2, for example, the net / wire 36 can be fractured under a good fracture shape with little deformation, and the mesh / wire 36 is intended to be used. The mesh / wire material 36 can also be made wider to some extent to reduce material restrictions.

Furthermore, when the cut-out portion 39 is cut from the main body portion 38 side of the plate / glass 35 with net / wire material, it is possible to eliminate the damage to the cut end faces 38a, 39a as described above. Therefore, by cleaning away the cullet powder generated by the scratches, it is possible to eliminate the troubles such as the scratches on the glass surface which are likely to occur secondarily.

[0029]

As described above, according to the present invention, the plate glass with the net / wire material continuously fed horizontally is provided with a cutting groove for partitioning the main body side and the cutout side. After that, by pushing down the cutout side and applying stress so that vertical cracks grow from the side of the cutting groove, the cutout part can be broken from the main body side while leaving the nets / wires connecting to each other. .

Under this condition, after the cutout portion is folded from the body portion side, the cutout portion side is held by a chuck, and a fulcrum near the body portion is pulled up, and at the same time, in the horizontal direction. By rapidly projecting, the residual mesh / wire material interposed between the main body portion and the cutout portion can be reliably broken under a strong tensile force.

For this reason, the net / wire remaining after connecting the main body portion and the cutout portion after the splitting should be broken without making the cut end face of the cutout portion abut against the cut end surface of the main body portion. As a result, it is possible to form a good quality cut end face without damaging the cut end face side, improve the product yield, and also improve the strength of the material used as a net or wire. The cullet powder is prevented from being generated by eliminating the damage on the cut end face side, and it is possible to have a wider selection range.Trouble such as damage to the glass surface that is likely to occur secondarily by the cullet powder. Can be wiped out.
