[Problems to be Solved by Invention]

The glass manufacturing apparatus is heated to the use temperature before starting to manufacture glass. At this time, each of the plurality of apparatuses constituting the glass manufacturing apparatus thermally expands. Therefore, in order to prevent the plurality of devices from interfering with each other, gaps are provided between the plurality of devices. However, if the gap is too large, the molten glass will leak. On the other hand, if the gap is too small, the adjacent devices will collide with each other and the devices will be damaged. If the device is damaged, the molten glass will come into contact with the surrounding bricks, etc., and the quality of the glass will be degraded. Moreover, the connection ports of adjacent apparatuses may shift in the direction orthogonal to the flow direction of molten glass. This deviation may cause the flow of molten glass to stagnate, resulting in defects such as streaks.

One aspect of the present invention provides a technique for suppressing the quality degradation of glass. [Technical means to solve problems]

[Effect of invention]

According to one aspect of the present invention, it is possible to suppress the deterioration of the quality of the glass.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each drawing, the same code|symbol is attached|subjected to the same or corresponding structure, and description may be abbreviate|omitted. In addition, in each drawing, the X-axis direction, the Y-axis direction, and the Z-axis direction are mutually perpendicular directions, the X-axis direction and the Y-axis direction are horizontal directions, and the Z-axis direction is a vertical direction. The X-axis direction is the flow direction of the molten glass, and the Y-axis direction is the width direction of the molten glass.

First, with reference to FIG. 1, the glass manufacturing apparatus 1 of this embodiment is demonstrated. The glass manufacturing apparatus 1 is provided with the melting apparatus 2, the conveying apparatus 3, the shaping|molding apparatus 4, the slow cooling apparatus 5, and the processing apparatus 6.

The melting apparatus 2 melts the glass raw material, and manufactures molten glass. The glass raw material is prepared by mixing a plurality of materials. The glass frit may also contain a clarifying agent. The clarifying agent is sulfur trioxide, chloride or fluoride, etc. In order to reuse the glass, the glass raw material may contain glass chips. The glass raw material may be a powder raw material or a granulated raw material obtained by granulating the powder raw material. The glass raw material is determined according to the composition of the glass.

The glass is, for example, alkali-free glass, aluminosilicate glass, borosilicate glass, soda lime glass, or the like. The alkali-free glass refers to a glass that does not substantially contain alkali metal oxides such as Na ₂ O and K ₂ O. Here, "substantially not containing alkali metal oxides" means that the total content of alkali metal oxides is 0.1 mass % or less.

The alkali-free glass is expressed in mass % based on oxide, for example, and contains SiO ₂ : 54% to 66%, Al ₂ O ₃ : 10% to 23%, B ₂ O ₃ : 6% to 12%, MgO+CaO+SrO+BaO: 8% ~26%.

In order to obtain a high strain point, the alkali-free glass preferably contains SiO ₂ : 54% to 68%, Al ₂ O ₃ : 10% to 25%, and B ₂ O ₃ : 0.1%～5.5%, MgO+CaO+SrO+BaO: 8%～26%.

The melting apparatus 2 is a continuous type, and continuously performs supply of glass raw materials and production of molten glass. The input amount per unit time of the glass raw material is the same as the discharge amount per unit time of the molten glass.

The conveyance apparatus 3 is located between the melting apparatus 2 and the shaping|molding apparatus 4, and conveys molten glass. The details of the conveying device 3 will be described later. Between the melting apparatus 2 and the shaping|molding apparatus 4, in addition to the conveying apparatus 3, the clarification apparatus 7 (refer FIG. 3) may be installed.

The refining device 7 removes the air bubbles contained in the molten glass before the molten glass obtained by the melting device 2 is formed by the forming device 4 . As a method of removing air bubbles, for example, at least one selected from the group consisting of a method of depressurizing the surrounding atmosphere of the molten glass and a method of heating the molten glass to a high temperature can be used.

The forming apparatus 4 forms the molten glass obtained by the melting apparatus 2 into glass of a desired shape. As a molding method for obtaining sheet glass, a float method, a melting method, a roll out method, or the like can be used. As a shaping|molding method to obtain a tubular glass, a Vello method, a Danner method, etc. can be used.

The slow cooling device 5 slowly cools the glass formed by the forming device 4 . The slow cooling device 5 has, for example, a slow cooling furnace and a conveyance roller for conveying glass in a desired direction inside the slow cooling furnace. For example, a plurality of conveying rollers are arranged at intervals in the horizontal direction. The glass is slow-cooled while being conveyed from the inlet of the slow-cooling furnace to the outlet. If the glass is cooled slowly, a glass with less residual strain can be obtained.

The processing apparatus 6 processes the glass after slow cooling by the slow cooling apparatus 5 into a desired shape. The processing device 6 may be one or more selected from, for example, a cutting device, a grinding device, a polishing device, and a coating device. The cutting device cuts the glass after slow cooling by the slow cooling device 5 . The cutting device forms a scribe line on the glass after slow cooling by the slow cooling device 5, for example, and cuts the glass along the scribe line. Scribing is formed using a cutter or laser light. The grinding device grinds the glass after slow cooling by the slow cooling device 5 . The grinding device grinds the glass after slow cooling by the slow cooling device 5 . The coating device forms a desired film on the glass after slow cooling by the slow cooling device 5 .

Next, with reference to FIG. 2, the manufacturing method of the glass of this embodiment is demonstrated. As shown in FIG. 2 , the glass manufacturing method includes melting (step S11 ), conveying (step S12 ), forming (step S13 ), slow cooling (step S14 ), and processing (step S15 ). The melting device 2 performs melting (step S11 ), the forming device 4 performs molding (step S13 ), the slow cooling device 5 performs slow cooling (step S14 ), and the processing device 6 performs processing (step S15 ).

In addition, the manufacturing method of glass may further include clarification. The fining removes the bubbles contained in the molten glass, and is performed after melting (step S11 ) and before forming (step S13 ). The clarification is performed, for example, in the middle of conveyance (step S12).

Next, the conveying apparatus 3 and the like will be described with reference to FIGS. 3 and 4 . The glass manufacturing apparatus 1 is equipped with the some conveyance apparatus 3A-3E between the melting apparatus 2 and the shaping|molding apparatus 4. Moreover, the glass manufacturing apparatus 1 is equipped with the some moving apparatus 8A-8E which individually moves the some conveying apparatus 3A-3E. The moving device 8A adjusts the position of the conveying device 3A in the first horizontal direction (for example, the X-axis direction) and the second horizontal direction (for example, the Y-axis direction) that is different from the first horizontal direction. Described below. Moreover, the moving device 8A adjusts the position of the conveying device 3A in the vertical direction. The same applies to the other mobile devices 8B to 8E.

As shown in FIG. 4 , when the heat rises, a gap is formed between the melting device 2 and the conveying device 3A. Moreover, when heat rises, a clearance gap is formed between adjacent conveying apparatuses (for example, the conveying apparatus 3A and the conveying apparatus 3B). When the heat rises, since the molten glass G is not conveyed, even if the gap is large, the molten glass G does not leak. It is possible to prevent the devices from interfering with each other and to prevent the devices from being damaged. As a result, it is possible to prevent the molten glass G from coming into contact with the heat insulating bricks and the like provided around the pipes 31A to 31D and the lip portion 37E described below to cause foreign matter to be mixed into the molten glass G at the time of glass production, thereby preventing the quality of the glass. decline.

After the thermal rise is completed and before the glass production starts, the gap between the melting device 2 and the conveying device 3A is narrowed in the X-axis direction to such an extent that the molten glass G does not leak. Similarly, the gap between the adjacent conveying apparatuses (for example, the conveying apparatus 3A and the conveying apparatus 3B) is narrowed in the X-axis direction. These gaps can also be narrowed to eventually disappear.

However, the heat rise may cause the connection ports of adjacent devices to be displaced in the direction orthogonal to the flow direction of the molten glass G (for example, the Y-axis direction or the Z-axis direction). If the glass production is started without this deviation, the flow of the molten glass G may be stagnant, and defects such as unevenness may be generated.

Therefore, in this embodiment, the conveyance apparatus 3A is moved in the Y-axis direction or the Z-axis direction with respect to the melting apparatus 2 after the completion of the thermal rise and before the start of glass production. Similarly, adjacent conveying apparatuses (for example, conveying apparatus 3A and conveying apparatus 3B) are moved relative to each other in the Y-axis direction or the Z-axis direction. Moreover, the conveying device 3E is moved in the Y-axis direction or the Z-axis direction with respect to the molding device 4 .

Then, as shown in FIG. 3, the conveyance apparatuses 3A-3E convey the molten glass G from the melting apparatus 2 to the shaping|molding apparatus 4, and manufacture of glass is started. Since the connection ports of adjacent devices are aligned with each other in advance, the flow of the molten glass G can be suppressed from being stagnant, and the occurrence of defects such as streaks can be suppressed.

As shown in FIG. 3 , a clarifying device 7 may also be provided between the melting device 2 and the forming device 4 . The clarification apparatus 7 is arrange|positioned, for example between the conveyance apparatuses 3A-3B and the conveyance apparatuses 3C-3E. Hereinafter, various apparatuses located between the melting apparatus 2 and the forming apparatus 4 will be described with reference to FIG. 3 .

The conveyance apparatus 3A contains the duct 31A which conveys the molten glass G. The conduit 31A forms a flow path of the molten glass G, and guides the molten glass G in a desired direction. The conduit 31A is made of metal, for example. The molten glass G can be heated by energizing and heating the metal conduit 31A.

The conduit 31A may be formed of, for example, a metal including at least one selected from platinum (Pt), rhodium (Rh), tungsten (W), iridium (Ir), and molybdenum (Mo). Metals include alloys. Pt, Rh, W, Ir and Mo are excellent in corrosion resistance to molten glass G.

Furthermore, the conduit 31A may be made of refractory bricks. From the viewpoint of being excellent in heat resistance and corrosion resistance to molten glass G, it is preferable to use an electroformed brick as the firebrick. The molten glass G can be heated by providing a heating device around the duct 31A. The same applies to the other conduits 31B to 31D.

The duct 31A includes, for example, a vertical pipe 32A opened above, and two horizontal pipes 33A and 34A. In the vertical pipe 32A, the stirring blade 101A of the stirring device 100A is inserted from above. The stirring apparatus 100A stirs and homogenizes the molten glass G inside the vertical pipe 32A. The vertical pipe 32A is provided between the two horizontal pipes 33A and 34A. The horizontal pipe 33A conveys the molten glass G from the melting device 2 to the vertical pipe 32A. The horizontal pipe 34A conveys the molten glass G from the vertical pipe 32A to the horizontal pipe 33B of the other conveying device 3B.

3A of conveyance apparatuses contain the heat insulating member 35A which heat-insulates the duct 31A, and the support member 36A which supports the duct 31A via the heat insulating member 35A. The heat insulating member 35A is made of ceramics such as heat insulating bricks. The support member 36A is not particularly limited, and is, for example, a mesh cage, which surrounds the heat insulating member 35A, and gathers a plurality of heat insulating bricks constituting the heat insulating member 35A into a desired shape.

The conveyance apparatus 3B contains the duct 31B which conveys molten glass G similarly to 3A of conveyance apparatuses. The duct 31B includes, for example, a vertical pipe 32B opened above, and a horizontal pipe 33B. In the vertical pipe 32B, the rising pipe 72 of the following clarification device 7 is inserted from above. The horizontal pipe 33B conveys the molten glass G to the vertical pipe 32B from the horizontal pipe 34A of the conveying device 3B. Like the conveyance apparatus 3A, the conveyance apparatus 3B may contain the heat insulating member 35B which heat-insulates the duct 31B, and may further contain the support member 36B which supports the duct 31B via the heat insulating member 35B.

The clarification device 7 includes, for example, a decompression defoaming tank 71 , an ascending pipe 72 , and a descending pipe 73 . The decompression defoaming tank 71 decompresses and defoams the molten glass G. The upper space of the decompression defoaming tank 71 is decompressed to a relatively low pressure. The rising pipe 72 is inserted into the vertical pipe 32B of the conveying device 3B from above, and the molten glass G is raised from the vertical pipe 32B to the decompression defoaming tank 71 by the air pressure difference. On the other hand, the descending pipe 73 is inserted into the vertical pipe 32C of the conveying device 3C from above, and the molten glass G is descended from the decompression defoaming tank 71 to the vertical pipe 32C by the air pressure difference.

3C of conveyance apparatuses contain the duct 31C which conveys molten glass G similarly to 3A of conveyance apparatuses. The duct 31C includes, for example, a vertical pipe 32C and a horizontal pipe 34C opened above. In the vertical pipe 32C, the descending pipe 73 of the clarification device 7 is inserted from above. The horizontal pipe 34C conveys the molten glass G from the vertical pipe 32C to the horizontal pipe 33D of the other conveying device 3D. Like the conveyance apparatus 3A, 3C of conveyance apparatuses may contain the heat insulating member 35C which heat-insulates the duct 31C, and may further contain the support member 36C which supports the duct 31C via the heat insulating member 35C.

The conveyance apparatus 3D contains the duct 31D which conveys molten glass G similarly to 3A of conveyance apparatuses. The duct 31D includes, for example, a vertical pipe 32D opened above, and two horizontal pipes 33D and 34D. In the vertical pipe 32D, the stirring blade 101B of the stirring device 100B is inserted from above. The stirring apparatus 100B stirs and homogenizes the molten glass G inside the vertical pipe 32D. The vertical pipe 32D is provided between the two horizontal pipes 33D and 34D. The horizontal pipe 33D conveys the molten glass G from the horizontal pipe 34C of the conveying device 3C to the vertical pipe 32D. The horizontal pipe 34D conveys the molten glass G from the vertical pipe 32D to the other conveying device 3E. Like the conveyance apparatus 3A, the conveyance apparatus 3D may contain the heat insulation member 35D which heat-insulates the duct 31D, and may further contain the support member 36D which supports the duct 31D via the heat insulation member 35D.

The conveying apparatus 3E is different from the other conveying apparatuses 3A-3D, and does not include the duct which conveys the molten glass G, and instead includes the lip part 37E which continuously supplies the molten glass G on the molten metal M. In this case, the shaping|molding apparatus 4 shape|molds the molten glass G into the glass ribbon of a strip shape by a float method. The forming apparatus 4 includes a float bath 41 in which the molten metal M is accommodated. The conveyance apparatus 3E contains the flow-path control shutter 38E which adjusts the flow rate of the molten glass G which flows over the lip part 37E. The larger the gap between the flow path control shutter 38E and the lip portion 37E, the larger the flow rate of the molten glass G is.

Furthermore, as described above, the forming method is not limited to the floating method. Moreover, as mentioned above, the clarification method is not limited to the vacuum defoaming method. Furthermore, the ducts 31A to 31D are not limited to the configuration shown in FIG. 3 . For example, the conduits 31A to 31D may also include inclined tubes inclined with respect to the horizontal plane. In addition, the position in the vertical direction of the horizontal pipes 33A and 34A may be different. The same applies to the horizontal tubes 33D and 34D.

Next, the mobile device 8A of the present embodiment will be described with reference to FIG. 5 . Since the other mobile devices 8B to 8E are configured in the same manner as the mobile device 8A shown in FIG. 5 , illustration and description thereof are omitted. The moving device 8A includes a horizontal direction adjustment mechanism 81 . The horizontal direction adjustment mechanism 81 adjusts the position of the conveying apparatus 3A in two directions of a first horizontal direction and a second horizontal direction different from the first horizontal direction.

Furthermore, in the present embodiment, the first horizontal direction is the X-axis direction, and the second horizontal direction is the Y-axis direction, but the technology of the present invention is not limited to this. By adjusting the positions of the transfer devices 3A in the two horizontal directions that are different from each other, a gap for preventing interference can be formed during the heat rise, and the deviation of the connection ports can be reduced after the heat rise is completed and before the glass production starts. shift.

The horizontal direction adjustment mechanism 81 includes, for example, a first unit 82 that adjusts the position of the conveying device 3A in the X-axis direction. Moreover, the horizontal direction adjustment mechanism 81 contains the 2nd unit 83 which adjusts the position of the conveying apparatus 3A in the Y-axis direction. The position of the conveying device 3A in the X-axis direction and the position of the conveying device 3A in the Y-axis direction can be adjusted individually.

The first unit 82 includes, for example, a bolt 82a and nuts 82b and 82c that are relatively rotatably coupled to the bolt 82a. The axial direction of the bolt 82a is the X-axis direction. The first unit 82 moves the conveying device 3A in the X-axis direction by the rotation of the bolt 82a or the nuts 82b and 82c.

On the other hand, in order to move the conveying device 3A in the positive X-axis direction, first, the nut 82b is loosened, and then the nut 82c is rotated to move the bolt 82a in the positive X-axis direction. After that, the worker or the working robot tightens the nuts 82b and 82c to restrict the movement of the conveying device 3A in the X-axis direction. To restrict movement, the nuts 82b, 82c may also be welded.

In addition, the number and position of the 1st measuring device 85 are not specifically limited. The number and position of the second measuring devices 86 are not particularly limited.

The operator or the working robot uses the first measuring device 85 and the second measuring device 86 to measure the position of the conveying device 3A in the X-axis direction and the position of the conveying device 3A in the Y-axis direction. If these positions are measured before and after the movement of the conveyance device 3A, the movement amount can be managed. Moreover, after the conveyance apparatus 3A moves, you may return the conveyance apparatus 3A to the original position.

The moving device 8A includes rolling elements between the conveying device 3A and the floor Fr. As the rolling elements, in the present embodiment, the first rollers 87a and the second rollers 88a are used as described below, but balls may also be used. The balls roll two-dimensionally. The moving device 8A may further include a guide rail for guiding the rolling elements. By arranging the rolling elements between the conveyance device 3A and the floor Fr, friction can be reduced and the conveyance device 3A can be easily moved.

The rotation center line of the 1st roller 87a is a Y-axis direction. The first roller 87a rolls in contact with the floor Fr. The first jack 87c is a panning screw jack, but may also be a screw jack, a hydraulic jack, or an air pressure jack other than the panning type.

When a worker or a work robot wants to move the conveying device 3A in the X-axis direction, the first roller 87a is in contact with the floor Fr, and neither the second roller 88a nor the following vertical direction adjustment mechanism 89 is in contact with the floor Fr. , the height of the conveying device 3A is adjusted in advance using the first jack 87c.

The height of the conveyance apparatus 3A is adjusted by the 2nd jack 88c. After that, the worker or the working robot moves the conveying device 3A in the Y-axis direction using the second unit 83 . At this time, the second roller 88a rolls in contact with the floor Fr.

The moving device 8A includes a vertical direction adjustment mechanism 89 that adjusts the position of the conveying device 3A in the vertical direction. The vertical direction adjustment mechanism 89 includes, for example, a screw jack, but may also include a hydraulic jack or a pneumatic jack. If the position of the conveying device 3A in the vertical direction is adjusted, the offset between the connection ports can be reduced after the thermal rise is completed and before the glass production starts.

The vertical direction adjustment mechanism 89 includes, for example, a bolt 89a and nuts 89b and 89c that are relatively rotatably coupled to the bolt 89a. The axial direction of the bolt 89a is the Z-axis direction. The vertical direction adjustment mechanism 89 moves the conveying device 3A in the Z-axis direction by the rotation of the bolt 89a or the nuts 89b and 89c.

To move the conveying device 3A in the positive Z-axis direction, first, the upper nut 89c is loosened, and then the lower nut 89b is rotated to move the nut 89b in the positive Z-axis direction. On the other hand, in order to move the conveying device 3A in the negative Z-axis direction, the lower nut 89b is rotated to move the nut 89b in the negative Z-axis direction. After that, the operator or the working robot tightens the nut 89c to restrict the movement of the conveying device 3A in the Z-axis direction.
