Description

TECHNICAL FIELD The present invention relates to a cutting method and a cutting apparatus for a meshed or lined glass plate (hereinafter referred to as a meshed glass plate) in which a wire net or a metal wire is placed inside a glass plate. Hereinafter, although a netted glass plate will be described, the object of the present invention includes a lined glass plate.

Netted glass plates are widely used for windows, stair fences, etc. in houses, buildings, schools, stores, etc., but when broken by impacts etc., they can prevent shattering and falling off of fragments, so as skylights, arcades, and top lights Often used when used. In addition, if a glass sheet with mesh is broken by fire in the event of a fire, it is difficult for fragments to fall off, and it has excellent fireproofing properties. A meshed glass is used for the doors and openings.

When producing the above-mentioned netted glass sheet, a product that is formed into a strip shape and is cut and cut in the width direction perpendicular to the sending direction, and then called ears at both ends in the width direction. Cut and remove thick parts that are out of specification or parts that are out of the measuring dimensions to make products.

However, unlike a normal plate glass without a mesh, the meshed glass plate must be cut and separated at the same time when the glass portion is cut into pieces, and the cut surface of the glass plate is cut when the wire mesh is cut. There is also a problem of lacking. Therefore, mechanization is difficult, and conventionally, the cutting of the meshed glass plate has been manually performed.

However, with the recent rise in labor costs, etc., such manual cutting of meshed glass sheets has become one of the factors that increase manufacturing costs. A method of cutting a glass plate using a mechanical device has been studied.

Patent Document 1 proposes a cutting method using a folding device as shown in FIGS. 6 (a) to 6 (d). In this folding apparatus, as shown in FIG. 6 (a), the net portion 202 is sandwiched by the sandwiching piece 205 to cut the meshed glass plate, but in (b) to (d), the sandwiching is performed. The piece 205 is omitted.

This folding device includes a holding piece 205 for holding the meshed glass plate 200, a holding piece driving mechanism for opening and closing the holding piece 205 (not shown), a four-bar parallel link mechanism (not shown), and a link driving mechanism (not shown). First, as shown in (a), a pinching piece drive mechanism (not shown) is driven to hold the ear portion 202 of the meshed glass plate 200 by the pinching piece 205 along the cut line 200a.

Next, as shown in (b), the clamping piece (not shown) is rotated clockwise in the drawing so that the portion of the incision 200a is at the center, whereby the mesh along the incision 200a. Only the glass part of the glass plate 10 is folded and divided into a main body part 201 and an ear part 202. As a result, end surfaces 201 a and 201 b are formed on the main body portion 201 and the ear portion 202.

Next, as shown in (c), by rotating the holding piece (not shown) holding the ear portion 202 counterclockwise in the drawing so that the remaining portion of the net 203 is centered. Then, most of the net 203 of the netted glass plate 200 is cut.
Finally, as shown in (d), the mesh 203 of the meshed glass plate 200 is completely cut by pulling the mesh 203 rightward in the figure by a clamping piece (not shown).

By using the above apparatus, it is possible to perform the cutting operation of the glass sheet with mesh while realizing labor saving.
However, since the ear part 202 is swung in a state of being completely clamped by the clamping piece 205, a large force may act on the end surface 201a of the main body portion 201 when the cut end surfaces 201a and 202a come into contact with each other. There is a problem that it is difficult to completely prevent the end surface 201a of the main body portion 201 from being chipped.

Other inventions related to the apparatus for cutting a meshed glass sheet include those described in Patent Documents 2 to 4, which all cut a belt-shaped meshed glass sheet that has been conveyed perpendicularly to the conveying direction. The invention is intended to be separated from the belt-like netted glass plate, and is slightly different from the method of cutting the ears.

The meshed glass plate 10 is split and cut in a direction (X direction) perpendicular to the transport direction at two previous steps, and then transported to split the ear 12.
As shown in FIG. 4, the splitting device 30 and the net material breaking device 60 are arranged in parallel to the glass conveyance path 200, and the folding device 30 enters the net on the back side of the conveyance path 200. The glass plate 10 is installed at a position close to the end face 10b cut in the direction (X direction) orthogonal to the transport direction. Although not shown, the folding device 30 and the net material breaking device 60 are provided in the left-right direction (both sides) of the glass conveyance path 200. On the side not shown, the folding device 30 is provided. And the net material breaking device 60 are reversed in position, and the folding device 30 is installed at a position near the end surface 10b of the netted glass plate 10 on the near side of the glass conveyance path 200.
This is because when lifting the meshed glass plate 10, it is necessary to lift the meshed glass plate 10 by moving the lifting bracket 49 (see FIG. 3) in the X direction so that it is below the cut line 10 a. This is because it is necessary to move the support plate 46 of the folding device 30 to a position closer to the conveyance path than the ear 12 at a position where it does not collide with the ear 12. Further, the position of the netted glass plate 10 that has been cut and conveyed is detected by a detection device (not shown), and stops at a predetermined position.

The position of the net material breaking device 60 is not particularly limited as long as the hand 101 can loosely insert the ear portion 12, and normally, as shown in FIG. 10 are arranged so as to be approximately in the center.

FIGS. 5A to 5D are explanatory views showing the method for cutting a meshed glass sheet according to the present invention.
In the method for cutting a meshed glass sheet according to the present invention, as shown in FIG.

In this glass plate lifting process, the meshed glass plate 10 enters the mesh from the standby position with the rod-shaped lifting bracket 49 constituting the folding device 30 after the cut lines are formed by the cutter provided in the conveyance path. The incisor 10a formed on the glass plate 10 or the incisor 10a is moved to a lower position closer to the ear than the incisor 10a. Thereafter, the lifting metal fitting 49 is raised and brought into contact with the meshed glass plate 10 at the part of the cut line 10a or the part closer to the ear part than the cut line 10a, and the meshed glass sheet 10 is further lifted.

It is desirable that the lifting metal fitting 49 has a rod shape (columnar shape) or a prismatic shape, and a portion in contact with the lower end surface of the meshed glass plate is a line contact, and is a straight line parallel to the cut line. There is no unevenness on the surface and it is only necessary to be flat, and the diameter and length in the case of the columnar shape or the prismatic shape are not particularly limited.

The lifting bracket 49 is coupled to a horizontal moving means (folding section reciprocating means) and a vertical moving means (folding section lifting / lowering means) via a member that supports the lifting bracket 49. Thus, it is possible to advance / retreat in the width direction (X direction), and ascend / descend from the outside of the ear 12 of the meshed glass plate 10. 5 (a) to 5 (b), only the meshed glass plate 10, the lifting metal fitting 49, the support plate 46, the holding metal fitting 48, and the glass plate supporting device 70 are shown, and other members are omitted. Yes.

The cut line 10a provided on the upper surface of the netted glass plate 10 is formed by a cutter (not shown), and the cut line is set at a position set on the basis of the transfer device 200 (see FIG. 4) for the netted glass plate. 10a is formed. Therefore, the position of the lifting bracket 49 advanced by the moving means can be set in advance so as to be a predetermined position just below the cut line 10a of the meshed glass plate 10 or slightly closer to the ear than directly below the cut line 10a. It ’s fine. You may make it move to a predetermined | prescribed position by detecting the position of the cut line 10a using an optical detection apparatus. “Slightly closer to the ear than the incisor 10a” means a position 20 mm closer to the ear than the position of the incisor 10a to the position of the incisor 10a. This is because, in this range, when the meshed glass plate 10 is folded in the next step, the end surface 11 a is perpendicular to the main surface of the meshed glass plate 10. When the position of the lifting metal fitting 49 is shifted to the main body 11 side rather than just below the cut line 10a, the main body 11 is folded so that the main body 11 is bent, and so-called cracks or the like are generated.

After that, as shown in FIG. 5A, the lifting metal fitting 49 is raised, for example, is brought into contact with the meshed glass plate 10 directly below the cut line 10a, and the meshed glass plate 10 is further lifted. When the meshed glass plate 10 is lifted, only a part of the meshed glass plate 10 is lifted up, and the other portions remain in their original positions, so that the meshed glass plate 10 is in the X direction and the Y direction ( The lifting bracket 49 itself is tilted so as to match this tilt, so that the meshed glass plate and the upper surface of the lifting bracket 49 are in linear contact with each other. This is because a concentrated load is applied to one part of the lifting metal fitting to prevent the glass from being cut and broken.

In the above-described splitting device 30 (see FIG. 2), when pressure is not applied to the piston rod 51a of the air cylinder 51 and the piston rod 51a is in a free state, the frame support plate 59 is free to rotate and can tilt. Accordingly, the lifting bracket 49 and the pressing bracket 48 that are supported and fixed to the frame support plate 59 and are in an interlocked state can also be tilted from the horizontal state. When the meshed glass plate 10 is tilted when 10 is lifted, the lifting bracket 49 is also tilted along the bottom surface of the meshed glass plate 10.

The lifting amount (lifting height) of the meshed glass plate 10 depends on the size of the meshed glass plate 10 and the like and cannot be generally specified, but is preferably about 5 to 20 mm. If the lifting amount is small, when the netted glass plate 10 is folded in the next process, the cut and cut surfaces on the side of the main body 11 are clogged and chipped. On the other hand, if the lifting amount is too large, The portion 12 side is folded so as to be bent, and so-called horns and burrs are generated.

The moving means of the lifting bracket 49 is not particularly limited, and for example, a combination of various actuators such as an air cylinder, a combination of a ball screw and a motor can be used.
When the above-described folding device 30 shown in FIG. 1 is used, the above-described glass plate lifting step is performed by driving the air cylinder 34 and the lifting cylinder 38 that constitute the folding device 30.

Next, a glass plate folding process is performed.
In the glass plate folding step, as shown in FIG. 5B, the presser fitting 48 provided so as to be parallel to the lifting bracket 49 is lowered so as to draw an arc with the lifting bracket 49 as an axis. Then, the raised ears 12 of the netted glass plate 10 are pushed down by the presser fitting 48, and only the glass part is folded and divided into the main body 11 and the ears 12, as shown in FIG.

In this process, the meshed glass plate is folded using the presser fitting 48, but the lower end of the glass plate is folded by lowering the presser fitting 48 so as to draw a substantially arc with the lifting bracket 49 as an axis. Therefore, a stress can be applied so that the crack progresses vertically from the side on which the cut line 10a is formed, and the meshed glass plate 10 can be folded at a right angle without generating an aggression or a chip.

Next, an ear loose insertion process is performed.
In this ear loose insertion step, as shown in FIG. 5C, the folded ear 12 connected to the main body 11 via the net 13 is substantially parallel to the main body 11. The air cylinder (hand reciprocating means) 102 is driven after being lifted and supported by the support 73, and a U-shaped cross section provided at the end of the piston rod 102a constituting the air cylinder (hand reciprocating means) 102. The hand 101 is moved forward with respect to the ear part 12, and the hand 101 and the ear part 12 are put into a loose insertion state.

The support tool 73 only needs to be coupled to a moving device that can lift and support the bent ear portion so as to be substantially parallel to the main body portion. A combination of reciprocating means capable of reversing and reciprocating means capable of ascending or descending may be used. As the reciprocating means, for example, combinations of various actuators such as an air cylinder, an oil cylinder, a combination of a ball screw and a motor can be used. In FIG. 5C, air cylinders 71 and 72 are used as support tool reciprocating means capable of moving forward or backward in the horizontal direction and support tool lifting means capable of moving up or down.

The hand reciprocating means is not particularly limited, and for example, combinations of various actuators such as an air cylinder, an oil cylinder, a combination of a ball screw and a motor can be used. In FIG. 5C, an air cylinder 102 is used as the hand reciprocating means.

The hand 101 has a U-shaped cross section. Although the configuration of the hand 101 is not shown in detail in FIG. 5C, for example, as shown in FIG. 3B, a predetermined interval is secured between the upper plate 101a and the lower plate 101b. The upper plate 101a and the lower plate 101b are supported by brackets 101c at the sides, and the ear portion 12 can be loosely inserted into the hand 101 having a U-shaped cross section. The thickness of the glass plate near the ear may be slightly thicker than the product plate thickness at the center, and the distance between the upper plate 101a and the lower plate 101b is the thickness of the netted glass plate 10. It is wider than that. The distance between the upper plate 101a and the lower plate 101b is preferably set to 1.5 to 2.0 times the thickness of the netted glass plate 10.

Next, a mesh material breaking step is performed.
In this mesh material breaking step, as shown in FIG. 5 (d), after the air cylinder (hand reciprocating means) is made reciprocally movable, the air cylinder (hand reciprocating means) is provided on the support plate 105. An air cylinder (hand turning means) 103 whose tip is pivotally supported in the middle part of 102 is driven, and the hand 101 (pivot part 104a) holding one end of the ear part 12 in the loosely inserted state is substantially centered on the split part. The pivot portion 104a is raised so as to draw an arc, and the net member 13 is broken.

In the above-mentioned ear loose insertion step, the end of the ear 12 is held in the hand 101 in a loosely inserted state. Subsequently, the air from the air cylinder (hand reciprocating means) 102 is removed, Make it reciprocating. The ear portion 12 is not sandwiched and fixed by the hand 101, and is in a state similar to that where one end of the ear portion 12 is placed in the hand 101, and the hand 101 is made of the netted glass plate 10. Since it can move freely with respect to the planar direction, when the ear 12 is in a horizontal state, the hand 101 is attached to a portion connected via the net member 13 or the end face of the ear 12 that is folded. Unreasonable force caused by the will not act.

The hand turning means is not particularly limited, and for example, combinations of various actuators such as an air cylinder, an oil cylinder, a combination of a ball screw and a motor can be used. In FIG. 5D, the air cylinder 103 is used as the hand turning means.

When the hand turning means is driven, as described above, the ear portion 12 and the hand 101 are held in the loosely inserted state, and the hand 101 holding one end of the ear portion 12 is substantially arcuate with a part of the folding portion 11a as a rotation center. In this case, the hand 101 is in a state in which one end of the ear 12 is loosely inserted, and the hand 101 can move freely with respect to the plane direction of the meshed glass plate 10. Since it is in a state, the net member 13 can be broken without an excessive force acting on the end surface of the main body 11 to cause peeling or the like.

The air cylinder (hand reciprocating means) 102 is disposed in a horizontal state on a table on which the air cylinder (hand reciprocating means) 102 is placed, but when the air cylinder (hand turning means) 103 is driven, the air cylinder (hand revolving means) 103 is driven. The pivot 104a moves up. At this time, the hand reciprocating means 99 and the ear portion 12 have a round shape and turn around the folding portion 11a. At the time of turning the hand 101, the ear portion slides while shifting on the surface in the U-shape of the hand 101, and the ear portion is turned around the cut line portion 10a, so that only the net member 13 is stretched and broken. To do.
