  The glass plate holder disclosed in Patent Document 1 is suitable for holding a glass plate having a relatively small external dimension. When the glass plate has a relatively large external dimension and a thin glass plate, Deflection deformation of the plate is likely to occur. This makes it difficult to stably hold the glass plate on the glass plate holder. For example, there has been a problem that the glass plates interfere with each other during the operation of holding the glass plate by the glass plate holder or the conveyance of the glass plate held by the glass plate holder, resulting in damage or damage.

It is preferable to include a displaceable second restricting member.

  Here, in a state where the movement of the first glass plate inserted into the slot is regulated by the regulating member, the second glass plate is inserted into the slot adjacent to the first glass plate, so that the second glass relative to the first glass plate is obtained. It is easy to avoid the collision of the plates. Furthermore, for example, in a state where the movement of the second glass plate inserted into the slot is regulated by the regulating member, the third glass plate is inserted into the slot adjacent to the second glass plate, so that a third relative to the second glass plate is obtained.

<Method for producing glass article>
Next, a method for manufacturing a glass article will be described together with a method (action) of using the glass plate holder 11 and an operation (action) of the glass plate movement restriction device 71.

The method for manufacturing a glass article includes a holding step of holding the glass plate G on the holder body 21 and a processing step of processing the glass plate G with a chemical strengthening liquid.
The holding process of this embodiment is performed using the glass plate holder 11 and the glass plate movement restricting device 71. The holding step includes a first stage in which the first glass plate G1 is inserted into the slot S, and a second stage in which the second glass plate is inserted into the slot S adjacent to the slot S in which the first glass plate G1 is inserted. .

  In the first stage of the holding process, the first glass plate G1 is inserted into the slot S of the holder body 21 by a glass plate supply device (not shown). The glass plate supply device is configured to hold the glass plate G from the glass plate G supply source and insert the glass plate G into the slot S.

  The first regulating member 62 of the glass plate movement regulating device 71 (glass plate holder 11) is driven (displaced) from the non-regulating position of the first glass plate G1 to the regulating position of the first glass plate G1 after the first stage. The At this time, the upper end insertion recessed part 61a in the 1st control member 62 of the glass plate holder 11 has a shape which becomes narrow as it goes inside. For this reason, when the 1st control member 62 is driven (displaced) to the control position of the 1st glass plate G1, the upper end part Ga of the 1st glass plate G1 does not collide easily with the opening end of the upper end insertion recessed part 61a. Moreover, in the 1st control member 62 of a control position, it is possible to raise the precision which controls the movement of the upper end part Ga of the 1st glass plate G1.

  FIG. 2A is a schematic side view showing the second stage, and FIG. 2B is a schematic plan view thereof. As shown in FIGS. 2A and 2B, the second stage of the holding process is performed in a state where the first restricting member 62 is located at the restricting position with respect to the first glass plate G1. Here, when the 1st glass plate G1 inserted in the slot S bends and deforms, the upper end part Ga of the 1st glass plate G1 moves relatively with respect to another part. When the movement of the upper end Ga of the first glass plate G1 proceeds, there is a possibility of colliding with the second glass plate G2 inserted into the slot S next to the first glass plate G1. In this regard, excessive movement of the upper end portion Ga due to the deflection deformation of the first glass plate G <b> 1 is restricted by the first restricting member 62.

In the second stage, the second glass plate G2 is inserted into the slot S adjacent to the slot S into which the first glass plate G1 is inserted by a glass plate supply device (not shown).
At this time, the movement of the upper end Ga of the first glass plate G1 inserted into the slot S is restricted by the first restricting member 62, and the slot S adjacent to the slot S into which the first glass plate G1 is inserted is Two glass plates G2 can be inserted. Thereby, it becomes easy to avoid the collision of the lower end part of the 2nd glass plate G2 with respect to the 1st glass plate G1.

  FIG. 3A is a schematic sectional side view showing a state in which the second restricting member 63 is displaced to the restricting position of the second glass plate G2, and FIG. 3B is a schematic plan view thereof. As shown in FIGS. 3A and 3B, after the second stage, the second restricting member 63 is driven from the non-regulating position of the second glass plate G2 to the restricting position of the second glass plate G2. (Displaced). At this time, the second restricting member 63 is also located at the restricting position with respect to the first glass plate G1.

  As described above, when the first glass plate G1 and the second glass plate G2 are sequentially regulated by the regulating member 61, the first regulating member 62 and the second regulating member 63 are alternately used, whereby the first regulating member 62 is used. As for either one of the second restricting member 63 and the second restricting member 63, it is possible to wait at the non-restricting position of the glass plate G to be restricted next. Thereby, it is possible to shorten the time from when the glass plate G is inserted into the slot S until it is regulated by the regulating member 61.

The holding step includes a third stage in which the third glass plate is held in the slot S adjacent to the slot S in which the second glass plate G2 is inserted.
FIG. 4A is a schematic sectional side view showing the third stage, and FIG. 4B is a schematic plan view thereof. As shown in FIGS. 4A and 4B, the third stage of the holding process is performed in a state where the second restricting member 63 is located at the restricting position with respect to the second glass plate G2. In the third stage, the third glass plate G3 is inserted into the slot S by the glass plate supply device as in the second stage. In the third stage, the first regulating member 62 is in a state of being positioned at a non-regulating position with respect to the third glass plate G3.

  Thus, in the state which controlled the movement of the upper end part Ga of the 2nd glass plate G2 inserted in the slot S with the 2nd control member 63, it is in the slot S adjacent to the slot S in which the 2nd glass plate G2 was inserted. A third glass plate G3 can be inserted. Thereby, it becomes easy to avoid the collision of the lower end part of the 3rd glass plate G3 with respect to the 2nd glass plate G2.

  FIG. 5A is a schematic sectional side view showing a state in which the first restricting member 62 is displaced to the restricting position of the third glass plate G3, and FIG. 5B is a schematic plan view thereof. As shown in FIG. 5A and FIG. 5B, after the third stage, the first regulating member 62 is driven from the non-regulating position of the third glass plate G3 to the regulating position of the third glass plate G3. Although not shown for the subsequent steps, the fourth step of inserting the fourth glass plate into the slot S is performed. Thus, in the holding step, the step of holding the glass plate G is repeated according to the number (N) of the glass plates G to be held by the holder main body 21.

  FIG. 6A is a schematic sectional side view showing a state where the third regulating member 64 is displaced to the regulating position of the glass plate G, and FIG. 6B is a schematic plan view thereof. As shown in FIGS. 6A and 6B, when the last glass plate GN is inserted into the slot S, the movement of the upper end Ga of all the glass plates G inserted into the slot S It is regulated by the third regulating member 64 of the plate holder 11. Thus, the holding process is completed. In addition, the 1st control member 62 and the 2nd control member 63 of the glass plate movement control apparatus 71 are driven to the position which can carry out the holder main body 21. FIG.

  Fig.7 (a) is a schematic sectional side view which shows the state of the glass plate G provided to a process, FIG.7 (b) is the schematic plan view. As shown in FIGS. 7A and 7B, the holder body 21 in a state where the movement of the upper end portion Ga of the glass plate G is regulated by the third regulating member 64 is used for the processing step in this state. Is done. In the processing step, the holder body 21 is immersed in the chemical strengthening solution. At this time, the chemical strengthening liquid flows into the holder body 21 and contacts the glass plate G, and the glass plate G is chemically strengthened.

  By treating the glass plate G with the chemical strengthening solution, ion exchange occurs in which ions contained in the glass plate G and ions contained in the chemical strengthening solution are exchanged. Is introduced. Thereby, the compressive-stress layer is formed in the chemically strengthened glass plate as an obtained glass article.

  Although a chemical strengthening liquid is not specifically limited, For example, a potassium nitrate liquid, a sodium nitrate liquid, and a potassium carbonate liquid are mentioned. For example, in the case of a potassium nitrate solution, the temperature of the chemical strengthening solution is preferably in the range of 350 to 550 ° C. The immersion time of the glass plate G in the chemical strengthening liquid is, for example, in the range of 1 to 8 hours.

  Here, when the movement of the upper end Ga of the glass plate G held by the holder main body 21 is not regulated in the conveyance from the holding step to the processing step or the processing step, the warp is caused by the deformation of the glass plate G. There exists a possibility that the chemically strengthened glass plate which it has may be obtained. In this regard, in the present embodiment, all the glass plates G held by the holder body 21 are in a restricted state using the third restricting member 64. Thereby, in the process of processing the glass plate G held on the holder main body 21 with the chemical strengthening liquid when the holder main body 21 holding the glass plate G is transported, the deformation of all the glass plates G is deformed. It is suppressed.

  The chemically strengthened glass plate that has completed the treatment process with the chemical strengthening solution is cleaned by the cleaning process. At this time, it is also possible to wash the chemically strengthened glass plate while being held by the holder body 21. Moreover, the chemically strengthened glass plate which completed the washing | cleaning process may be dried. At this time, it is also possible to dry the chemically strengthened glass plate while being held by the holder body 21.

According to the embodiment detailed above, the following effects are exhibited.

It is configured to be displaceable. According to this configuration, the movement of the glass plate G is restricted by the restriction member 61 (the first restriction member 62, the second restriction member 63, or the third restriction member 64) displaced to the restriction position. The bending deformation of the inserted glass plate G is suppressed. Thereby, the glass plate G can be stably held by the holder main body 21.

  (2) The holder body 21 of the glass plate holder 11 includes a plurality of slots S into which a plurality of glass plates G can be inserted. The restriction member 61 of the glass plate holder 11 includes a first restriction member 62 and a second restriction member 63. In this case, when the movement of the glass plate G is sequentially regulated by the regulating member 61, the first regulating member 62 and the second regulating member 63 are alternately used, so that the first regulating member 62 and the second regulating member 63 are used. About either of these, it can be made to stand by in the non-regulation position with respect to the glass plate G which it is going to regulate next. Thereby, it is possible to shorten the time from when the glass plate G is inserted into the slot S until it is regulated by the regulating member 61. Therefore, the efficiency of the holding process for holding the glass plate G on the holder body 21 can be increased.

  (3) The restriction member 61 of the glass plate holder 11 further includes a third restriction member 64. The third restricting member 64 can be displaced to a restricting position with respect to all the glass plates G inserted into the slots S. In this case, when the holder body 21 holding the glass plate G is transported or in the processing step of processing the glass plate G held on the holder body 21 with the chemical strengthening liquid, all the glass plates G are bent and deformed. It is suppressed. Thereby, since the curvature of the chemically strengthened glass plate as a glass article obtained is suppressed, it is advantageous in terms of improvement in yield and quality in the chemically strengthened glass plate.

For this reason, it is advantageous from the viewpoint of improving the yield and quality of the chemically strengthened glass plate.

  (9) The holding step of the glass article manufacturing method includes a first step of inserting the first glass plate G1 into the slot S, and a second glass plate in the slot S adjacent to the slot S into which the first glass plate G1 is inserted. A second stage of inserting G2. This 2nd step is performed in the state where the 1st control member 62 of the glass plate movement control apparatus 71 (glass plate holder 11) was located in the control position with respect to the 1st glass plate G1.

  According to this method, the slot adjacent to the slot S in which the first glass plate G1 is inserted in a state where the movement of the upper end portion Ga of the first glass plate G1 inserted in the slot S is regulated by the first regulating member 62. The 2nd glass plate G2 can be inserted in. Thereby, it becomes easy to avoid the collision of the lower end part of the 2nd glass plate G2 with respect to the 1st glass plate G1. Therefore, the glass plate G can be stably held by the holder main body 21.

(Example of change)
The above embodiment may be modified as follows.
-The 3rd control member 64 of the glass plate holder 11 may be abbreviate | omitted. In this case, for example, the movement of the upper end portions Ga of all the glass plates G inserted into the slots S can be restricted using the first restricting member 62 or the second restricting member 63. Specifically, for example, an attachment / detachment mechanism capable of attaching / detaching the first restriction member 62 to the first drive unit 81 of the glass plate movement restriction device 71 is provided. Then, after the first restricting member 62 is positioned at the restricting position with respect to all the glass plates G inserted into the slots S, the first restricting member 62 is detached from the first driving portion 81. However, in this case, the first restricting member 62 is transported together with the holder main body 21, and when driving the first restricting member 62, it takes time to attach to and detach from the first drive unit 81. Become. Thus, since the handling of the 1st control member 62 or the 2nd control member 63 becomes complicated, it is preferable that the glass plate holder 11 is provided with the 3rd control member 64. FIG.

  The restriction member 61 of the glass plate holder 11 may be configured only from the first restriction member 62. In this case, the glass plate G hold | maintained at the holder main body 21 can be controlled in order by displacing the 1st control member 62. FIG.

  The restriction member 61 of the glass plate holder 11 may be configured only from the third restriction member 64. Even in this case, since the bending deformation of the glass plate G inserted into the slot S is suppressed, the glass plate G can be stably held by the holder main body 21.

  -The 1st control member 62 and the 2nd control member 63 of the said glass plate holder 11 are comprised so that all the glass plates G inserted in the slot S can be controlled. At least one of the first regulating member 62 and the second regulating member 63 is not limited to a configuration capable of regulating all the glass plates G, and may be changed to a configuration capable of regulating one or more glass plates G. . In this case, when the glass sheets G are sequentially inserted into the slots S, the movement of the glass sheets G that are already inserted in the slots S adjacent to the slots S into which the glass sheets G are to be inserted can be restricted. Thereby, the glass plate G can be inserted and held smoothly.

  However, the first restricting member 62 and the second restricting member 63 are the first and last glass plates G to be inserted into the slot S first, from the viewpoint of more stably holding the glass plate G in the holder body 21. When the glass plate G inserted into the Nth is N-th, it is preferable to be configured as follows. That is, one of the first restriction member 62 and the second restriction member 63 is configured such that the first to (N-1) th glass plates G are restricted, and the other is from the first to the (N-2) th. It is preferable that the glass plate G is configured to be regulated. One of the first restricting member 62 and the second restricting member 63 is configured such that the first to Nth glass plates G are restricted, and the other is the first to N−1th glass plates. It is more preferable that G is regulated.

  -The number of the regulating members 61 of the glass plate holder 11 may be changed as appropriate. For example, the glass plate holder 11 is changed to a configuration including a fourth restriction member that can be displaced independently of any of the first restriction member 62, the second restriction member 63, and the third restriction member 64. Also good. For example, the fourth restricting member restricts the movement of the upper end portion Ga of the glass plate G when the glass plate G is sequentially inserted into the slot S, similarly to the first restricting member 62 and the second restricting member 63. Can be used. The fourth restricting member may be used to restrict the movement of the upper end portions Ga of all the glass plates G inserted into the slots S, similarly to the third restricting member. Also in the glass plate movement restricting device 71, the number of restricting members 61 may be changed as appropriate.

  -In the glass plate movement control apparatus 71, any one of the 1st drive part 81 and the 2nd drive part 91 may be abbreviate | omitted. Further, the glass plate movement restriction device 71 may be changed to a configuration further including a third drive unit that drives the third restriction member 64. The third regulating member 64 is detachably provided on the third drive unit.

  -As shown to Fig.8 (a) and FIG.8 (b), the regulating member 61 of the glass plate holder 11 may be changed into the caterpillar type regulating member 65 which has a caterpillar structure. The caterpillar type regulating member 65 includes a band body 65a and a roller 65b around which the band body 65a is wound. The band 65a has an upper end insertion recess 61a into which the upper end Ga of the glass plate G is inserted. The caterpillar type restricting member 65 shown in FIGS. 8A and 8B is a restricting position with respect to the first glass plate G1, and the second glass plate G2 is inserted into the slot S in this state. Then, as shown in FIGS. 9A and 9B, after the second glass plate G2 is inserted into the slot S, the caterpillar type regulating member 65 is advanced to move the caterpillar type regulating member 65 to the first one. 2 Displaced to the restriction position with respect to the glass plate G2. Thus, with the caterpillar type regulating member 65, it is easy to sequentially regulate the movement of the upper end portion Ga of the glass plate G inserted into the slot S. The caterpillar type regulating member 65 may be manually operated or may be driven by a drive unit.

  -Although the shape of the upper end insertion recessed part 61a which the regulating member 61 in the said glass plate holder 11 has is a shape which becomes narrow as it goes inside, it is not limited to this, For example, it is wide as it goes inside. The shape may be changed.

  -Although the restriction member 61 of the said glass plate holder 11 has the upper end insertion recessed part 61a, it may be changed into the restriction member which abbreviate | omitted the upper end insertion recessed part 61a. For example, even if it changes to the control member which has a flat surface which presses the upper end part Ga of the glass plate G, the movement of the upper end part Ga of the glass plate G is controlled by the press. However, the restricting member having the upper end insertion recess 61a is advantageous in that the upper end Ga of the glass plate G can be suppressed from being excessively loaded and the movement of the upper end Ga can be restricted. It is further advantageous to have a shape that becomes narrower toward the inside.

  -About the regulation member 61, such as the said glass plate holder 11, the shape, a dimension, etc. may be changed suitably. For example, the first restricting member 62 may be changed so as to simultaneously restrict a plurality of portions in the upper end portion Ga of one glass plate G.

  In the glass plate holder 11 or the like, for example, the first restriction member 62 and the caterpillar type restriction member 65 may be combined to implement a combination of restriction members having different mechanisms or shapes.

  The first restricting member 62 and the second restricting member 63 of the glass plate holder 11 are configured to be driven by the first drive unit 81 and the second drive unit 91, respectively, but are all performed manually. May be configured. The holding step of the glass article manufacturing method can also be performed manually.

  -The 1st drive part 81 of the glass plate movement control apparatus 71 is not limited to the 1st vertical drive part 82 and the 1st horizontal drive part 83, It changes into the other mechanism which can drive the 1st control member 62 to a predetermined position. May be. Also about the 2nd drive part 91 of the glass plate movement control apparatus 71, you may change into another mechanism.

  The holder body 21 is arranged so that the glass plate G is inserted along the vertical direction, but the holder is so inserted that the glass plate G is inclined with respect to the vertical direction. The main body 21 may be disposed to be inclined with respect to the horizontal plane.

  The holder body 21 may be changed to a horizontal type so that the glass plate G is inserted into the slot S along a substantially horizontal direction. In this case, the lower end support part 41 may be omitted. In the horizontal holder main body, for example, a bending deformation occurs in which the glass plate G already inserted into the slot S becomes convex downward. Regarding the progress of the bending deformation, by restricting the movement of the end portion of the glass plate G by the regulating member 61, the glass plate G can be stably held by the holder main body 21. Thus, in the glass plate G, the part by which a movement is controlled using the control member 61 is not limited to upper end part Ga.

-In the said holder main body 21, the shape of the lower end support part 41 or the side end holding part 51, the number, and the fixed position with respect to the main body frame 31 may be changed suitably.
-Although the said holder main body 21 is used for the use which hold | maintains the glass plate G when processing the glass plate G with a chemical strengthening liquid, for example, it is used when processing the glass plate G other than a chemical strengthening solution. Also good. Examples of the treatment of the glass plate G other than the chemical strengthening liquid include, for example, a heat treatment for heating the glass plate G held by the holder main body 21, a cleaning process for washing the glass plate G held by the holder main body 21, and a holder. The drying process which dries the glass plate G hold | maintained at the main body 21 is mentioned. Further, the holder body 21 may be used for a reforming process in which the glass plate G held by the holder body 21 is modified with a liquid. The holder body 21 may be used for a single process or may be used for a plurality of processes.

  -The composition and application of the glass plate G are not particularly limited. The glass plate G may be non-alkali glass, for example. Examples of the use of the glass plate G include display use, touch panel use, photoelectric conversion panel use, electronic device use, window glass use, building material use, and vehicle use.
