Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a first glass sheet and a second glass sheet which are opposed to each other while sandwiching a plurality of spacers distributed in the plane direction of the first glass sheet and the second glass sheet, and then fired to form the first glass sheet and the second glass sheet. A spacer arrangement method for a glass panel that seals the second glass sheet over the entire circumference, and the first glass sheet and the second glass sheet sandwich a plurality of spacers distributed in the plane direction thereof, The present invention relates to a glass panel manufacturing apparatus for obtaining a glass panel in which the first plate glass and the second plate glass are sealed all around.

[0002]

2. Description of the Related Art Conventionally, as a glass panel of this kind,
For example, there is a vacuum glass in which the internal space sandwiched between two glass sheets made of a first glass sheet and a second glass sheet is reduced to a substantially vacuum state to improve heat insulation and sound insulation. In the vacuum glass, a plurality of spacers are arranged between the first glass sheet and the second glass sheet in order to maintain the internal space at a predetermined interval while resisting an atmospheric pressure from the outside.

The spacer is made of a small member made of aluminum or the like so as not to be noticeable. However, when a person approaches the vacuum glass, the existence of the spacers becomes apparent. Therefore, it is necessary to arrange the plurality of spacers in order to improve the appearance.

[0004] The operation of arranging the spacers is usually carried out by using a spacer arranging apparatus on the upper surface of the first plate glass held in a substantially horizontal direction. That is, the spacers are arranged on the upper surface of the first glass sheet while setting the positions at predetermined intervals. In this arrangement, the spacers are simply placed on the upper surface of the first glass sheet without using an adhesive or the like. Done. This is because, when an adhesive is used, it is difficult to apply the adhesive to all the spacers under the same conditions, so that the excess adhesive overflows around the spacer, The overflowing excess adhesive may impair the transparency of the vacuum glass, and may cause a problem that the adhesive is gasified and the degree of vacuum is impaired even after the vacuum glass is installed in a building. On the other hand, even if an adhesive or the like is not used, when the vacuum glass is completed, the spacer is stably held because the first plate glass and the second plate glass are subjected to the atmospheric pressure.

[0005]

However, after arranging the spacers on the upper surface of the first glass sheet and before completing the vacuum glass, for example, placing the second glass sheet temporarily on the spacer. Placement step, a sealing step of adhesively sealing the periphery of the first sheet glass and the second sheet glass with low-melting glass, and further sealing the pressure reducing hole provided in the second sheet glass while depressurizing the internal space. It is necessary to go through a reduced pressure sealing step to be performed.

Conventionally, there has been a tendency that the position of the spacer is shifted during the progress of these steps. Such displacement may occur, for example, when the second glass sheet collides with the spacer when the second glass sheet is placed on the spacer, or the second glass sheet may be finely adjusted to finely adjust the position of the placed second glass sheet. When the glass sheet is moved, the spacers are simultaneously moved, and the first glass sheet and the second glass sheet are moved.
When the sheet glass is heat-sealed, the sheet glass vibrates due to the convective air in the heating furnace, and the like, and this is caused.

[0007] Such a positional deviation can be relatively easily solved by rearranging the positions of the spacers at the stage of temporarily placing the second glass sheet.
For example, it has been extremely difficult to correct a position shift or the like that has occurred after the sealing of the peripheral portion has been completed. Therefore, conventionally, in order to prevent the displacement of the spacer, it is necessary to handle the first glass sheet and the second glass sheet with extreme care, and the production efficiency of vacuum glass is low. In addition, it is difficult to completely prevent the displacement of the spacer even if the work is performed carefully,
There are also certain limits to improving the yield associated with the production of vacuum glass.

An object of the present invention is to solve the above-mentioned conventional problems and to provide a glass panel spacer arranging method and a glass panel manufacturing apparatus capable of stabilizing the position of the spacer when manufacturing a glass panel via the spacer. To provide.

Have. [Function and Effect] As in this means, if the water content on the surface of the first glass sheet is set to be larger than the water content on the surface of the second glass sheet, the adhesive force between the first glass sheet and the spacer is set stronger. be able to. That is, by securing a predetermined amount of water between the first glass sheet and the spacer, it is considered that the adhesive force between the first glass sheet and the spacer is increased by a force such as hydrogen bonding due to water or surface tension of water. Therefore, according to the present means, for example, when the spacer is sandwiched between the first glass sheet and the second glass sheet, it is possible to minimize the disturbance of the arrangement position of the spacer, thereby improving the manufacturing efficiency of the glass panel. At the same time, the quality of the glass panel and the yield of the glass material at the time of manufacturing can be improved.

It is characterized in that, after the plurality of spacers S are placed in contact with the first glass sheet G1, the second glass sheet G2 is overlapped. [Function and Effect] As in the present means, of the two end faces of the spacer, the water content of the first end face contacting the first sheet glass is set to be larger than the water content of the second end face contacting the second sheet glass. If so, it is only necessary to add a minimum amount of water necessary for attaching the spacer. In other words, in the case of the present means, the amount of water to be supplied is much smaller than in the case where water is added to the entire surface of the first plate glass, for example. Therefore, not only the drying process after the spacer is sandwiched between the first glass sheet and the second glass sheet is simplified, but also

It is characterized in that a water amount setting device for setting a water amount larger than the water amount between the second plate glass G2 and the spacer S is provided. [Operation and Effect] If the apparatus for manufacturing a glass panel according to this configuration is used, for example, the water content on the surface of the first glass sheet can be set to be larger than the water content on the surface of the second glass sheet. As described above, the adhesive force between the first glass sheet and the spacer can be set to be stronger than the adhesive force between the second glass sheet and the spacer. Therefore, if the present manufacturing apparatus is used, for example, when the spacer is sandwiched between the first glass sheet and the second glass sheet, it is possible to minimize the disturbance of the arrangement position of the spacer, thereby improving the manufacturing efficiency of the glass panel. In addition, the quality of the glass panel and the yield of the glass material at the time of manufacturing can be improved.

Further, the present invention relates to an apparatus for manufacturing the glass panel. Examples of the glass panel according to the present invention include a vacuum glass panel and a multilayer glass panel. Among them, the present embodiment shows an example of manufacturing a vacuum glass panel.

In the present invention, the position of the spacer S is stabilized by adjusting the amount of water existing between the spacer S and the two glass sheets G. For example, the amount of water between the first glass sheet G1 and the spacer S is set to be larger than the amount of water between the second glass sheet G2 and the spacer S, and the adhesion between the first glass sheet G1 and the spacer S is set to be stronger. By doing so, it is possible to minimize the disturbance of the arrangement position of the spacer S when sandwiching the spacer S.
When adjusting the amount of moisture, it can be determined that the adhesive force tends to increase as the amount of moisture between the spacer S and the plate glass G increases. Then, it is considered that the adhesive force is determined by a synergistic effect of hydrogen bonding by moisture and surface tension of water. An experimental example showing the relationship between the water content and the adhesive force will be described later.

(First Embodiment) FIG. 1 shows a manufacturing process of a glass panel according to a first embodiment. Manufacturing a glass panel can be roughly classified into a washing / drying step of the sheet glass G, a spacer arranging step, a sealing step, and a decompression / sealing step.

While being placed on the placing device 1, the sheet is conveyed by a conveying device 2 such as a belt conveyor 2a. At the time of mounting on the mounting device 1, a plurality of points on the lower surface of the first sheet glass G1 are point-supported. By minimizing the contact area between the mounting device 1 and the first glass sheet G1 as described above, it is possible to prevent the cleaning liquid or the like from remaining on the contact portion and becoming dirty on the glass surface. The second glass sheet G2 is conveyed while being suspended by the suspension device 3. The suspension is performed by, for example, sucking and supporting a plurality of locations on the upper surface of the second glass sheet G2 with the suction cup 3a or the like, and engaging and supporting a plurality of locations on the peripheral edge portion using a claw member.

The transported first glass sheet G1 and second glass sheet G2 are cleaned by the cleaning device 4. The cleaning is performed, for example, on the first sheet glass G1 and the second sheet glass G2.

a and the degree of drying in the second drying device 5b are determined by measuring the humidity inside the two drying devices 5 or indirectly recognizing the degree of drying by measuring the temperature, or by directly detecting the moisture content on the surface of the sheet glass G. The dryness is directly recognized by contacting the measuring means.
For this reason, the drying control device 8 controls the heating temperature of the heater 6, the blowing amount of the blower 7, and the like by recognizing and comparing the drying degrees of the first drying device 5 a and the second drying device 5 b. Thus, the degree of drying of the first glass sheet G1 and the second glass sheet G2 is determined. In the present embodiment, the surface moisture content of the first plate glass G1 is set to be large.

<Spacer arranging step> The spacer arranging step is a step of temporarily placing a plurality of spacers S on one of the first glass sheet G1 and the second glass sheet G2. The plurality of spacers S are arranged by the spacer arrangement device 9. As shown in FIGS. 2A and 2B, the spacer arrangement device 9 includes, for example, an upper plate member 9a and a lower plate member 9b, and is configured to be able to move up and down. A plurality of holes 9c are formed in each of the plate members 9a and 9b in accordance with the position of the spacer S. When mounting the spacer S, the upper and lower plate members 9a, 9
b are displaced relative to each other in the plane direction X, for example, by the radius of the hole 9c. That is, the spacer S enters the hole 9c of the upper plate member 9a, and is prevented from falling by the lower plate member 9b. When the spacer S is placed on the upper surface of the first glass sheet G1, the holes 9c of the upper and lower plate members 9a and 9b are aligned, and the spacer S is dropped on the upper surface of the first glass sheet G1. is there. FIG. 3A shows a state in which the spacer S is dropped. In FIG. 3A, a layer W having a large amount of water is formed on the surface of the first plate glass G1. FIG. 4 shows a state in which the arrangement of the spacers S has been completed.

Conversely, when the surface moisture content of the second glass sheet G2 is set to be larger than the surface moisture content of the first glass sheet G1, and a plurality of spacers S are adsorbed and arranged on the lower surface of the second glass sheet G2. In such a case, the spacers S may be lifted and attached to the lower surface of the second glass sheet G2 in such a state that the holes 9c of the upper plate member 9a and the lower plate member 9b do not coincide with each other. This embodiment is illustrated in FIG.

2 is a step of depressurizing the internal space formed in step 2 and sealing the space in this state with respect to the external space. Although not shown, the glass panel on which the four sides have been sealed is conveyed to the inside of the vacuum sealing device. By depressurizing the inside of the decompression sealing device, the internal space is also depressurized. For this purpose, for example, a decompression hole 11 is provided in advance at a corner of the second glass sheet G2.

The pressure in the internal space is reduced to a predetermined value,
In this state, the pressure reducing hole 11 is sealed. For the sealing, a sealing stopper 12 also made of low-melting glass 10 is used. The state is shown in FIG. Specifically, the sealing plug 12 previously formed in accordance with the shape of the pressure reducing hole 11 is inserted into the pressure reducing hole 11, and the sealing plug 1
