Description

Glass plate manufacturing method and manufacturing apparatus

The present invention relates to a glass plate manufacturing method including a step of processing an end face of the glass plate, and a glass plate manufacturing apparatus for executing the method.

As is well known, in the manufacturing process of a glass plate, the glass plate is often cut in order to cut it into a product size. Since the end face of the glass plate formed along with the cutting contains a large number of defects such as microcracks, the end face of the cut glass plate is subjected to grinding, etc. for the purpose of removing these defects. It is customary to carry out the processing step.

Here, Patent Document 1 discloses an example of a specific mode for executing the above-described steps. In the aspect disclosed in this document, each of the parallel both end faces of the glass plate protruding from the work table in a state where the rectangular glass plate is placed and fixed on the work table (precision surface plate). In contrast, grinding is performed with a grindstone.

A large number of suction holes are formed on the mounting surface of the glass plate provided in the work table, and the glass plate is fixed to the work table by the suction holes adsorbing the glass plate. In the same aspect, suction holes are uniformly formed on the mounting surface so as to fix the entire glass plate to the work table, except for the portion protruding from the work table.

However, when the end face of the glass plate is processed in the above-described manner, there are the following problems to be solved.

That is, in the end face processing of the glass plate, a part of the glass plate is cut by a grindstone to become glass powder. Further, the grindstone is consumed by the processing, and abrasive grains and bonds are separated from the grindstone to become grindstone scraps. And in said aspect, there exists a difficulty that the quality of a glass plate falls easily resulting from glass powder or grinding stone waste. The reason for this is that when the glass plate is fixed to the work table, the lower surface is easily scratched by glass powder or grinding stone scraps sandwiched between the lower surface of the glass plate and the mounting surface of the work table. .

Further, although not limited to the process of processing the end face, it is required to reduce the cost required for each manufacturing process as much as possible when manufacturing the glass plate. From the viewpoint of cost reduction, there is still room for improvement in the above aspects.

The present invention made in view of the above circumstances has a technical problem to suppress the deterioration of the quality of the glass plate and reduce the cost for processing when processing the end face of the glass plate.

The present invention devised to solve the above-mentioned problems is a glass plate including an end face processing step for processing the end face of the glass plate protruding from the support stage in a state where the glass plate is fixed on the support stage. The manufacturing method is characterized in that the support stage is provided with a fixing portion that can fix the glass plate and a support portion that supports the glass plate with a plurality of elastic members.

In this method, it is possible to suppress the deterioration of the quality of the glass plate due to glass powder or grinding stone scraps. This is because, in the support portion provided on the support stage, even if glass powder or the like is sandwiched between each of the plurality of elastic members and the lower surface of the glass plate, It is because it can suppress that the lower surface of damaging. In addition, according to the present method, it is possible to reduce the cost required for the end face processing step by the amount that the support portion is provided on the support stage. This is because the support part does not have a mechanism for fixing the glass plate, so that the operation cost of the mechanism for fixing is inevitably unnecessary, and high accuracy is required for the installation of the elastic member. Because there is nothing to do. In addition, although the mechanism for fixing a glass plate does not exist in a support part, a support stage can fix a glass plate by a fixing part. For this reason, this method can perform an end face processing process without a problem. From the above, according to this method, when processing the end face of the glass plate, it is possible to suppress the deterioration of the quality of the glass plate and reduce the cost for processing.

In the above method, the support portion is preferably a brush support portion that supports the glass plate with a brush.

In this way, even if glass powder or the like is sandwiched between the brush tip and the lower surface of the glass plate, the lower surface of the glass plate is damaged by the glass powder or the like because the brush hair is bent. It can be effectively suppressed.

In the above method, when the glass plate has a rectangular shape and both end faces extending in parallel with each other in the end face processing step are processed, the support stage is provided with a fixed portion along the both end faces. A first outer fixing portion and a second outer fixing portion extending are provided, the first outer fixing portion is disposed closer to one of both end surfaces than the support portion, and the second outer fixing portion is positioned at both ends of the support portion. It is preferable to arrange it close to the other surface.

In this way, since the peripheral portion of the end face of the glass plate is fixed by the outer fixing portion, the processing accuracy of the end face can be improved.

In the above method, it is preferable that the support portion extends along the direction in which both end surfaces extend.

When processing both end surfaces of the glass plate extending in parallel with each other, the glass plate before processing is carried into the support stage using a transport belt capable of transporting the glass plate in a direction parallel to the both end surfaces. At the same time, the processed glass plate may be unloaded from the support stage. For this reason, if the support portion extends along the direction in which both end surfaces extend, the conveyance belt and the support portion extend in parallel, and it is ensured that the support portion obstructs the operation of the conveyance belt. Can be avoided.

In the above method, it is preferable to provide the support stage with an inner fixing portion disposed between the first outer fixing portion and the second outer fixing portion as the fixing portion.

In this way, the fixing by the outer fixing portion can be assisted by the inner fixing portion, and the glass plate can be fixed more firmly. For this reason, even if it is a large sized glass plate (For example, the glass plate which is 1000 mm or more in length and 1000 mm or more in width), the processing precision of an end surface can be improved.

In the above method, it is preferable that the support stage has a symmetric configuration with respect to an axis of symmetry extending in parallel with both end faces.

In this way, a force acts equally on the glass plate on the support stage from the support stage on both the part existing on one side of the axis of symmetry and the part existing on the other side. This is advantageous in accurately executing the end face machining process.

The above method preferably includes a positioning step of positioning the glass plate by moving it on the support stage before the end face processing step.

In this way, it is possible to improve the processing accuracy of the end face by executing the positioning step before the end face processing step. Furthermore, in this method, by providing the support portion on the support stage, the following effects can be obtained at the time of performing the positioning step. That is, when the glass plate is moved on the support stage for positioning, the resistance applied to the glass plate can be suppressed, so that the glass plate can be easily moved as desired. As a result, positioning accuracy can be improved. In addition, when the glass plate is flexible, it is likely that it is difficult to move the glass plate on the support stage. Can be moved easily.

In the above method, the fixing portion supplies a fluid between the suction hole that sucks and fixes the lower surface of the glass plate when the end face processing step is performed, and between the fixing portion and the lower surface of the glass plate when the positioning step is performed. It is preferable to have a supply port.

In this way, when the end face processing step is executed, the end face can be processed favorably by adsorbing and fixing the lower surface of the glass plate with the suction holes at the fixing portion. In addition, when performing the positioning process, by supplying fluid from the supply port between the fixed part and the lower surface of the glass plate, resistance applied to the glass plate can be suppressed, so the glass plate is moved as desired. It becomes easy to let you.

In the above method, it is preferable that the number of suction holes of the first outer fixing portion and the second outer fixing portion is larger than the number of suction holes of the inner fixing portion.

Here, when both the outer fixing portion and the inner fixing portion are compared, the inner fixing portion has a smaller influence on fixing in the vicinity of both end faces. If the above-mentioned composition is adopted, the neighborhood of the both end faces in a glass plate can be fixed firmly efficiently.

In the above method, after the end face processing step is performed, when the releasing step of releasing the fixing of the glass plate by the fixing portion by injecting gas from the suction hole is included, the suction holes are arranged along the direction in which both end faces extend. The suction hole array and the supply port array in which the supply ports are arranged along the direction in which both end surfaces extend are disposed in the fixed portion, and the suction hole array in the suction hole array and the supply port array is disposed in the fixed portion. It is preferable to arrange it close to the end face close to.

In this way, when the suction hole array is close to the end face, the glass plate is more easily released in the release process than when the supply port array is close to the end face. For this reason, even if it cancels fixation of a glass plate at a cancellation | release process, the trouble which a glass plate and a fixing | fixed part closely_contact | adhere can be reduced.

In addition, the present invention created to solve the above-mentioned problems protrudes from a support stage that can be fixed in a state where the glass plate is supported from below and a support stage of the glass plate that is fixed on the support stage. An apparatus for manufacturing a glass plate provided with an end face processing means for processing an end face, wherein the support stage has a fixing portion that can fix the glass plate and a support portion that supports the glass plate with a plurality of elastic members. Characterized by In this apparatus, the support part is preferably a brush support part that supports the glass plate with a brush.

According to this glass plate manufacturing apparatus, it is possible to obtain the same actions and effects as the above glass plate manufacturing method.

According to the present invention, when processing the end face of the glass plate, it is possible to suppress the deterioration of the quality of the glass plate and to reduce the cost for processing.

A plurality of (in this embodiment, five) conveyor belts 4 are wound around a drive pulley and a driven pulley (not shown), between blocks B and C, between blocks D and E, and between blocks F and G. , And extends between the blocks H and I and between the blocks J and K along the feed direction. Each transport belt 4 can change the height position of the transport surface 4a by an elevator mechanism (not shown).

The plurality of conveyor belts 4 can sequentially perform the following operations (1) to (3) in a synchronized state.

(1) First, when the glass plate 2 is carried into the support stage 3, the height position of the transport surface 4 a of each transport belt 4 is set to the support surface 12 of the outer fixing portion 9 and the inner fixing portion 10, and the brush. The glass plate 2 is conveyed in the feed direction in a state where it is higher than the hair ends.

(2) When the glass plate 2 reaches the support stage 3, the height position of the transport surface 4a is gradually lowered. And if the height position of the conveyance surface 4a becomes lower than the support surface 12 of the outer side fixing | fixed part 9 and the inner side fixing | fixed part 10, and the hair tip of a brush, the glass plate 2 will receive to the support stage 3 from each conveyance belt 4. Passed. As a result, the glass plate 2 is supported by the outer fixing portion 9, the inner fixing portion 10, and the brush support portion 11. Each transfer belt 4 after delivering the glass plate 2 to the support stage 3 waits until the processing of both end faces 2a, 2a is completed in the space S formed between the blocks arranged on both sides of the conveyor belt 4. . In addition, the width of the space S along the arrangement direction is wider than the width of each conveyance belt 4.

(3) When the processing of both end faces 2a, 2a is completed, the height position of the transport surface 4a is gradually raised. And if the height position of the conveyance surface 4a becomes higher than the support surface 12 of the outer side fixing | fixed part 9 and the inner side fixing | fixed part 10, and the hair tip of a brush, the glass plate 2 will receive to each conveyance belt 4 from the support stage 3. Passed. Finally, the glass plate 2 is transported in the feed direction in a state where the height position of the transport surface 4a is higher than the support surface 12 of the outer fixed portion 9 and the inner fixed portion 10 and the brush tip. Thereby, the glass plate 2 is carried out from the support stage 3.

As shown in FIG. 1, two pressing members 5 are arranged. Each of the two units includes a columnar tip portion 5a that abuts one of the two end faces 2a and 2a, and an actuator 5b for moving the tip portion 5a in the U direction.

The positioning pins 6 are arranged side by side along the feed direction. Each positioning pin 6 can stop the movement of the glass plate 2 along the U direction by coming into contact with the other of the both end faces 2a, 2a.

When the glass plate 2 is positioned, the pressing member 5 and the positioning pin 6 cooperate as follows. Initially, the front-end | tip part 5a of the pressing member 5 contact | abuts one of the both end surfaces 2a and 2a. And the glass plate 2 is pushed to the U direction by the front-end | tip part 5a which moved toward the U direction by the actuator 5b. When the other end face 2a, 2a comes into contact with the positioning pin 6 and the movement of the glass plate 2 is stopped, the positioning of the glass plate 2 is completed. After the positioning is completed, both 5 and 6 are separated from the glass plate 2 and retreat to a position where contact with the grindstone 7 can be avoided.

The grindstone 7 is arranged for grinding one of the two end faces 2a and 2a and for grinding the other. Each of the grindstones 7 and 7 moves in the T3 direction along a linear track by being guided by a guide (not shown) while rotating around an axis extending in the vertical direction. The T3 direction of the present embodiment is opposite to the feed direction, but may be the same direction. In the present embodiment, both the grindstones 7 and 7 perform grinding while running in parallel with the glass plate 2 interposed therebetween.

Hereinafter, the manufacturing method of the glass plate using said manufacturing apparatus 1 is demonstrated.

Here, the thickness of the glass plate 2 to be processed on both end faces 2a and 2a is not particularly limited, but in the present embodiment, a thickness that can provide flexibility (for example, 700 μm or less). The glass plate 2 formed in (1) is the object of processing.

First, the glass plate 2 whose both end faces 2a, 2a are not processed (unprocessed) is carried into the support stage 3 by a plurality of conveyor belts 4.

Next, the glass plate 2 carried into the support stage 3 is supported by the outer fixing part 9, the inner fixing part 10, and the brush support part 11. At this time, the glass plate 2 is not fixed to the support stage 3. Then, as a positioning step, the glass plate 2 is positioned on the support stage 3 by both the pressing member 5 and the positioning pins 6. When this positioning step is executed, fluid is supplied from the supply port 14 in each of the outer fixing portion 9 and the inner fixing portion 10.

Next, when the positioning process is completed, the supply of fluid from the supply port 14 is stopped in each of the outer fixing portion 9 and the inner fixing portion 10. The supply of fluid from the supply port 14 may be continued. Then, the glass plate 2 is fixed on the support stage 3 by adsorbing and fixing the lower surface 2 b of the glass plate 2 through the adsorption holes 13. And as an end surface processing process, it grinds with respect to the both end surfaces 2a and 2a of the glass plate 2 with both the grindstones 7 and 7. FIG. After the end face processing step is completed, gas is injected from the suction holes 13 to release the suction, and the fixation of the glass plate 2 to the support stage 3 is released (release step).

Finally, the glass plate 2 after both end faces 2a, 2a are processed (processed) is unloaded from the support stage 3 by a plurality of conveyor belts 4.

Hereinafter, main actions and effects of the manufacturing apparatus 1 and the glass plate manufacturing method using the manufacturing apparatus 1 will be described.

According to the manufacturing apparatus 1 and the glass plate manufacturing method described above, in the brush support portion 11 provided on the support stage 3, glass powder or grinding stone waste is between the brush tips and the lower surface 2 b of the glass plate 2. Even if it is pinched, since the hair of the brush has elasticity, the hair of the brush bends. For this reason, it can suppress that the lower surface 2b of the glass plate 2 is damaged with glass powder or grindstone scraps. Therefore, it can suppress that the quality of the glass plate 2 falls due to glass powder or grinding stone scrap. Furthermore, since the mechanism for fixing the glass plate 2 does not exist in the brush support part 11, the operating cost of the mechanism for fixing becomes unnecessary, and high accuracy is required for the installation of the brush. Therefore, the cost for processing the end face 2a can be reduced.

In the present embodiment, the outer fixing portion 9 and the inner fixing portion 10 extend along the end surface 2a of the glass plate 2, and the brush support portion 11 is arranged along the direction in which the end surface 2a of the glass plate 2 extends. Other configurations may be adopted. For example, you may employ | adopt the structure which arrange | positions a brush support part inside it while arrange | positioning a fixing | fixed part in loop shape. Or you may employ | adopt the structure which arrange | positions both a fixing | fixed part and a brush support part in zigzag form.

From the viewpoint of further suppressing the deterioration of the quality of the glass plate 2 and further reducing the cost, the occupation ratio of the brush support portion 11 is preferably 5% or more, and more preferably 20% or more. On the other hand, from the viewpoint of securely fixing the glass plate 2 to the fixing portion, the occupation area of the brush support portion 11 is preferably 90% or less, and more preferably 70% or less. Here, the occupation ratio of the brush support part 11 means that the area of the brush support part 11 (the area of the block on which the brush support part 11 is arranged) is the total area of the brush support part 11, the outer fixing part 9 and the inner fixing part 10. This is the ratio of the total area of all blocks.

In this embodiment, the brush support portion 11 that supports the glass plate 2 with a plurality of elastic members is used as a support portion that supports the glass plate 2, and each bristle group 16 included in the brush constitutes an elastic member. However, the present invention is not limited. For example, instead of the bristle group 16, the elastic member of the support portion may be constituted by the rod-like member 17 shown in FIG. 3, the coil spring-like member 18 shown in FIG. 4, or the plate-like member 19 shown in FIGS. 5a and 5b. Good. In order to facilitate understanding of the drawings, FIGS. 3 to 5b show only a part of the glass plate 2 and the elastic members 17 to 19 of the support portion, and the other components are not shown.

When the rod-like member 17 and the coil spring-like member 18 are employed, the lower ends in the vertical direction (longitudinal direction) of both the members 17 and 18 are fixed to the flat plate 15 (not shown in FIGS. 3 and 4), and the upper ends are It contacts the glass plate 2. Each of the members 17 and 18 can be deformed by expanding and contracting in the vertical direction according to the force applied to itself. Here, as a material of the rod-shaped member 17, for example, sponge, rubber, urethane, silicone, NC nylon, or the like can be employed. Further, as the material of the coil spring-like member 18, for example, sponge, rubber, urethane, silicone or the like can be adopted.

When the plate-shaped member 19 is employed, the main surface (front and back surfaces) is arranged so as to be parallel to the vertical surface, and the lower end surface of the plate-shaped member 19 is a flat plate 15 (not shown in FIGS. 5a and 5b). The upper end surface (tip) is in contact with the glass plate 2. Further, the main surface of the plate-like member 19 may be parallel to the alignment direction as shown in FIG. 5a, or may be parallel to the feed direction as shown in FIG. 5b. Furthermore, the main surface of the plate-like member 19 may be inclined with respect to both the feeding direction and the arrangement direction. A plurality of the plate-like members 19 are arranged along the thickness direction. Each plate-like member 19 can be deformed so that its upper end surface (tip) is displaced in the thickness direction as shown by a double-ended arrow in FIG. Here, as a material of the plate-like member 19, for example, sponge, rubber, urethane, silicone or the like can be adopted.

When the rod-shaped member 17, the coil spring-shaped member 18, or the plate-shaped member 19 is used, the glass has a elasticity between the tip (upper end) of the member and the lower surface 2 b of the glass plate 2 because the members have elasticity. Even if powder or grinding stone waste is caught, the member is deformed accordingly. Therefore, it can suppress that the quality of the glass plate 2 falls due to glass powder or grinding stone scrap.
