Description

Manufacturing method of glass plate package and glass plate package

The present invention relates to a method for producing a glass plate package and a glass plate package.

Large-sized glass plates used in flat display devices such as liquid crystal display devices, organic EL display devices, and plasma display devices are not in direct contact with each other during storage, packaging, or transfer to the next process. In this way, a slip sheet is sandwiched between adjacent glass plates to prevent scratches, breakage, adhesion between the glass plates, and the like.

The process of laminating the slip sheet on the glass plate surface when assembling such a glass plate package is, for example, the surface of the glass plate that is about to lean diagonally on the diagonally stacked pallet, or the flat plate pallet from now on. This is done by stacking slip sheets on the surface of the glass plate to be tried.

In Patent Document 1, as shown in FIG. 8, both upper corners of the slip sheet 2 are gripped by gripping portions 51, 51 such as a cylinder or a holding chuck, and two upper sides of the slip sheet 2 are suspended by the gripping portions 51, 51. A configuration in which an interleaving paper gripping means 50 is provided is disclosed.

Japanese Unexamined Patent Publication No. 2007-000940

However, in the configuration as described in the cited document 1, several glass plates may be damaged when the glass plate package is unpacked during use. As a result of intensive studies by the inventors of the present application, when the glass plate is loaded on the pallet with the configuration as in the cited document 1, the position where the slip sheet is intended due to the influence of the wind caused by the surrounding environment. Problems such as laminating from the stack, laminating with interleaving on the interleaving paper, laminating with the interleaving paper folded, etc. have occurred frequently, resulting in unintended load on the glass plate I found out.

In view of such a background, the present invention mainly aims to provide a method for producing a glass plate package and a glass plate package that are less likely to damage the glass plate.

In order to achieve the above object, the present invention provides a method for producing a glass plate package, characterized in that the glass plate is placed on a pallet in a state where a glass plate and a slip sheet are adhered.

According to the present invention, it is possible to provide a method for manufacturing a glass plate package and a glass plate package that are less likely to damage the glass plate.

Hereinafter, the glass plate which concerns on one Embodiment of this invention is demonstrated using drawing.

In the drawings for explaining the embodiment of the present invention, coordinates are defined by an arrow at the lower left in the figure, and explanation will be made using these coordinates if necessary. In this specification, the “X direction” refers not only to the direction from the root of the arrow indicating the X coordinate to the tip, but also to the direction from the tip inverted by 180 degrees to the root. Similarly, “Y direction” and “Z direction” indicate not only the direction from the root to the tip of the arrows indicating the Y and Z coordinates, respectively, but also the direction from the tip to the root that is opposite by 180 degrees. In the present specification, the tip side of the arrow in the Z direction is also referred to as “up” and the root side of the arrow is also referred to as “down”.

In the present specification, the term “lamination” does not only refer to stacking slip sheets and / or glass plates on a horizontal glass plate, but includes, for example, slip sheets and / or the surface of inclined or vertical glass plates. The concept includes the overlapping of glass plates.

(First embodiment)
Drawing 1 is a figure showing the manufacturing method of the glass plate packing object of a 1st embodiment of the present invention. FIG. 1 shows a glass plate handling having a suction pad 106 at the tip of a pallet 105 of an oblique vertical type composed of a base part 101, a back part 102, an inclined pedestal part 103, and an inclined backrest part 104. The glass plate 108 is placed on the pallet 105 by the device 107.

Here, the glass plate 108 and the slip sheet 109 are placed on the pallet 105 in an attached state. It is possible to suppress the occurrence of problems such as the slip sheet 109 being stacked out of the intended position, the slip sheet 109 being stacked with wrinkles, and the slip sheet 109 being stacked in a folded state. Thus, a glass plate package in which the glass plate is hardly damaged can be produced.

In this embodiment, the adhesion between the glass plate 108 and the interleaf paper 109 is performed through the adhesive 110 between the glass plate 108 and the interleaf paper 109. Through the adhesive material 110, the glass plate 108 and the interleaf paper 109 can be firmly attached.

It is preferable that the adhesive 110 has a 180 ° peeling adhesive strength defined by JIS Z 0237 of 10 N / 25 mm or more and 20 N / 25 mm or less. The slip sheet 109 can be attached to such an extent that it cannot move freely, and the slip sheet 109 can be easily peeled off from the glass plate 108 during unpacking.

In addition, it is preferable that the adhesion material 110 has an interaction distance of a Hansen solubility parameter (also referred to as HSP) with respect to water at 25 ° C. of 17 or less. Since the adhering material 110 is easily dissolved in water, the adhering material 110 remaining on the surface of the glass plate 108 can be easily removed by cleaning the glass plate 108 after unpacking.

Here, the Hansen solubility parameter is an index indicating the ease of dissolving a certain solute in a certain solvent. Further, the interaction distance Ra (also referred to as HSP vector distance Ra) obtained from the value of the Hansen solubility parameter of the first additive in water is represented by the following equation (1).

Ra ₁ = (4 × (δ _D1 −18.1) ² + (δ _P1 −17.1) ² + (δ _H1 −16.9) ² ) ^0.5 (1)
Ra ₁ : Interaction distance of Hansen solubility parameter in water δ _D1 : Of the Hansen solubility parameter of additive, dispersion force term δ _P1 : Of Hansen solubility parameter of additive, dipole force term δ _H1 : Of the Hansen solubility parameters, the hydrogen bond strength term

The Hansen solubility parameter is a three-dimensional space where the solubility parameter introduced by Hildebrand is divided by Hansen into three components: a dispersion term δ _D , a polar term δ _P , and a hydrogen bond term δ _H. It is a thing. The dispersion term δ _D indicates the effect due to the dispersion force, the polar term δ _P indicates the effect due to the force between the dipoles, and the hydrogen bond term δ _H indicates the effect due to the hydrogen bond force. The closer the coordinates of a specific substance X in a three-dimensional space are to the coordinates of a certain solvent, the easier the substance X is dissolved in the solvent. Details of the definition and calculation method of Hansen Solubility Parameters are described in the following literature; Hansen, “Hansen Solubility Parameters: A Users Handbook”, CRC Press, 2007.

In addition, by using computer software (Hansen Solubility Parameters in Practice (HSPiP)), the Hansen solubility parameter can be easily estimated from the chemical structure.

In the present invention, HSPiP version 4.1.07 is used, and the value is used for substances registered in the database, and the estimated value is used for substances not registered.

2 is a view of the glass plate 108, the interleaf 109, and the adhering material 110 from the direction from the tip of the arrow to the base in the Y direction in the state of FIG. 1 (the glass plate handling device 107 is not suitable). (Illustrated).

The glass plate 108 and the slip sheet 109 are preferably attached in the peripheral region of the glass plate 108 as shown in FIG. Specifically, the adhering material 110 is disposed in the peripheral region of the glass plate 108 and adheres the glass plate 108 and the slip sheet 109. The glass plate 108 and the slip sheet 109 may be attached only in the peripheral region. Since the peripheral area is removed in the process of becoming the final product or is hardly visible in the final product, it is not necessary to excessively consider the residue of the adhesion material 110 on the glass plate 108. In other words, the influence on the glass surface due to the residue of the adhering material 110 can be minimized.

Here, the “peripheral region” refers to, for example, a region that occupies a width of 20 mm from the contour line of the glass plate 108 to the inner side in a plan view from the thickness direction of the glass plate 108. In FIG. 2, the region surrounded by the outline of the glass plate 108 and the broken line 201 is indicated.

In FIG. 2, the adhering material 110 is arranged as an enclave at each corner of the glass plate 108, but may be arranged as a straight line or a frame shape along the side of the glass plate 108.

Further, as shown in FIG. 2, it is preferable that the corner portion 202 of the interleaf paper 109 is attached to the glass plate 108. Since the corner portion of the slip sheet 109 is particularly easily swayed, it is possible to more effectively suppress the occurrence of problems such as the slip of the slip sheet 109 and the lamination of the slip sheet 109 in a folded state.

Here, the “corner portion 202 of the slip sheet 109” refers to a region surrounded by an alternate long and short dash line in FIG. 2, for example, a circle having a radius of 50 mm inscribed in two sides forming the corner of the slip sheet 109. Refers to a range. Further, “the state in which the corner portion 202 of the interleaf paper 109 is attached to the glass plate 108” means that the entire area of the corner portion 202 may be attached to the glass plate 108. As shown in FIG. It is assumed that a part of the region may be attached to the glass plate 108. Further, only the corner portion 202 of the interleaf paper 109 may be attached to the glass plate 108. The effect can be obtained efficiently with a small adhesion area.

Further, the attachment of the glass plate 108 and the slip sheet 109 may be performed at any timing from the sampling of the glass plate 108 to the placement on the pallet 105. For example, the glass plate 108 is prepared in a state where the main surface is parallel to the ground, the adhering material 110 is disposed on the main surface of the glass plate 108, and the slip sheet 109 is laminated thereon, and the glass plate 108-adhering material 110 -A laminate of slip sheets 109 may be formed and then laminated to the pallet 105 using the glass plate handling device 107. At this time, the glass plate handling device 107 may hold the glass plate 108 directly with the suction pad 106, and the glass plate 108 is sucked through the slip sheet 109 in consideration of the air permeability of the slip sheet 109. You may hold | maintain with the pad 106. FIG. When the glass plate 108 and the slip sheet 109 are attached in this manner, in the present embodiment, since the pallet 105 is an obliquely placed type, the glass plate 108 has a main surface from a state in which the main surface is parallel to the ground surface. The posture changes to a state in which is tilted with respect to the ground. As described above, in the present embodiment, the process of changing the posture of the glass plate 108 in the process of placing the glass plate 108 on the pallet from the state in which the slip sheet 109 is attached can be included. A variety of glass plates can be conveyed until the placement on the pallet is completed.

This embodiment is suitably used for a rectangular slip sheet 109 having a side of 800 mm or more. When the size of one side of the slip sheet 109 is 800 mm or more, it is easy to swing when placed on the pallet by an external force such as wind, but this can be suppressed by using this embodiment. The size of one side of the interleaving paper 109 is preferably 1000 mm or more, more preferably 1200 mm or more, and further preferably 1500 mm or more.

In addition, although this embodiment showed the form of the diagonally stacked pallet, it is not limited to this. A flat pallet can be used similarly. The conceptual diagram is shown in FIG. In the case of a flat pallet, for example, the glass plate 108 is prepared in a state where the main surface is parallel to the ground, the adhering material 110 is arranged on the main surface of the glass plate 108, and the slip sheet 109 is laminated thereon, A laminate of the plate 108, the adhering material 110, and the interleaf paper 109 is formed, and then the glass plate 108 is held by the suction pad 106 via the interleaf paper 109 and placed on the pallet using the glass plate handling device 107. In this case, the movement of the slip sheet 109 is suppressed to some extent by the suction pad 106, but the slip sheet 109 in a portion where the suction pad 106 does not exist may move due to wind during glass conveyance or vibration during placement. It was. According to the present embodiment, such movement of the slip sheet 109 can be suppressed. In particular, the movement of the peripheral edge and corner of the slip sheet can be suppressed.

Note that application to a flat pallet is not limited to the first embodiment. It can be suitably used as a modification of the second embodiment and the third embodiment.

In FIG. 1 and FIG. 7, the thickness of the adhering material 110 is intentionally thick for easy understanding, but the thickness of the adhering material 110 is compared with that of the glass plate 108 and the interleaf paper 109. It can be very thin. Therefore, in FIG. 7, the glass plate 108 is held by suction on the suction pad 106.

(Modification)
FIG. 3 is a diagram showing a modification of the first embodiment of the present invention. First, in (a), a glass plate laminate 301 constituted by a plurality of alternately laminated glass plates 108 and a plurality of interleaving papers 109 is prepared in front of the pallet 105. At this time, the glass plate 108 and the interleaf paper 109 may be laminated in advance at different locations, and the glass plate laminate 301 may be conveyed to the front of the pallet 105. Alternatively, the glass plate laminate 301 may be formed by laminating the glass plate 108 and the interleaf paper 109 in front of the pallet 105. Further, in the case of this modification, the glass plate 108 and the slip sheet 109 may be bonded to the uppermost pair of the glass plate laminate 301 via the adhesive material 110. This is because the lower glass plate 108 and the interleaf paper 109 of the uppermost pair are difficult to move when placed due to the weight of the uppermost pair. Or it is good also as a state which made the pair of all the glass plates 108 and the slip sheets 109 adhere with the adhesive material 110. FIG.

Next, as shown in (b), a part of the conveyor 303 moves while the glass plate laminate 301 is in contact with the receiving plate 302. A part of the conveyor 303 operates as indicated by an arrow in (b) so that the glass plate laminate 301 rises with an inclination with respect to the horizontal plane (XY plane).

Then, as shown in (c), the glass plate laminated body 301 is placed so as to collapse onto the pallet 105, and a part of the conveyor 303 returns to the original position again until a sufficient amount is loaded on the pallet 105. Repeat (a) to (c).

With the configuration of the modified example, since the glass plate 108 and the interleaf paper 109 can be processed for each batch without being placed one by one on the pallet 105, efficient placement is possible.

In addition, since only the uppermost pair of the glass plate laminate 301 can be attached, productivity is improved as compared to the case where all the pairs are attached.

Note that this modification is not limited to the first embodiment. It can be suitably used as a modification of the second embodiment and the third embodiment.

(Second Embodiment)
Drawing 4 is a figure showing the manufacturing method of the glass plate packing object of a 2nd embodiment of the present invention. In addition, the same code | symbol is attached | subjected to what has the structure similar to 1st Embodiment, and description is abbreviate | omitted. Further, the description regarding the attached range, interpretation of terms, modification examples, and the like is the same as that of the first embodiment unless otherwise specified.

In the second embodiment, adhesion between the glass plate 108 and the slip sheet 109 is performed by passing moisture between the glass plate 108 and the slip sheet 109. The glass plate 108 and the interleaving paper 109 can be temporarily attached through the moisture.

The moisture may be, for example, a liquid sprayed or may penetrate into the interleaf paper 109. Specific examples of the liquid used as moisture include pure water and alcohol. It is preferable that the glass plate 108 and the slip sheet 109 are not affected and the foreign matter contained in the slip sheet 109 is not dissolved. When the glass plate 108 is used as a final product, it is possible to make it difficult for defects to exist in the glass surface.

Also, the liquid used as moisture is preferably volatile at room temperature (for example, 20 degrees). If the glass plate 108 and the slip sheet 109 are attached only until the glass plate laminate is placed on the pallet 105 and then volatilizes, the surface quality of the glass plate 108 can be obtained even if the entire surface of the glass plate 108 is attached. The impact on the can be reduced.

In the second embodiment, it is preferable that after the droplets are sprayed on the surface of the glass plate 108 or the surface of the interleaf paper 109, the glass plate 108 and the interleaf paper 109 are brought into contact with each other and adhered. By spraying, the glass plate 108 and the interleaving paper 109 can be adhered uniformly, and both can be prevented from containing excessive moisture. For example, the glass plate 108 is prepared in a state where the main surface is parallel to the ground, the liquid is sprayed by the spray device toward the upper surface of the glass plate 108, and the slip sheet 109 is laminated thereon, and the glass plate 108-adhesive material A laminated body of 110-interleaf paper 109 may be formed and then laminated on the pallet 105 using the glass plate handling device 107. Note that the spraying of the liquid by the spray device may be performed on the interleaf sheet 109 side.

(Third embodiment)
FIG. 5 is a diagram showing a method for manufacturing a glass sheet package according to a third embodiment of the present invention. In addition, the same code | symbol is attached | subjected to what has the structure similar to 1st Embodiment, and description is abbreviate | omitted. Further, the description regarding the attached range, interpretation of terms, modification examples, and the like is the same as that of the first embodiment unless otherwise specified.

In the third embodiment, the adhesion between the glass plate 108 and the slip sheet 109 is performed by generating a Coulomb force between the glass plate 108 and the slip sheet 109. By using the Coulomb force, the glass plate 108 and the slip sheet 109 can be temporarily attached. Moreover, since the Coulomb force is attenuated with time, it is possible to make it difficult for defects to exist in the glass surface when the glass plate 108 is used as a final product.

The Coulomb force is a force that works between charged particles, and what is used in this embodiment is an attractive force that works between charges of different signs in the Coulomb force.

In FIG. 5, the Coulomb force is generated between the glass plate 108 and the slip sheet 109 by bringing the electrode 501 having a voltage of 10 kV or more as an absolute value closer to the glass plate 108 and / or the slip sheet 109. In the case where the electrode 501 is brought close to the glass plate 108, it is preferable that the electrode 501 has a positive voltage in consideration of the charging property between the glass plate 108 and the interleaf paper 109. As a result, of the positive ions and negative ions generated when corona discharge occurs, the negative ions are attracted to the electrode side, and the positive ions are easily applied to the glass plate 108. As a result, the Coulomb force can be efficiently applied. On the other hand, when the electrode 501 is brought close to the slip sheet 109, it is preferable that the electrode 501 has a negative voltage in consideration of the charging property between the glass plate 108 and the slip sheet 109. As a result, of the positive ions and negative ions generated when corona discharge is generated, positive ions are attracted to the electrode side, and negative ions are easily applied to the interleaf 109. As a result, the Coulomb force can be efficiently applied.

Further, the absolute value of the voltage of the electrode 501 is preferably 15 kV or more, more preferably 20 kV or more, further preferably 25 kV or more, and further preferably 30 kV or more. Coulomb force can be applied efficiently in a short time. The upper limit is not particularly limited, but is preferably 50 kV or less in consideration of the influence on the glass plate 108 and the slip sheet 109.

In this embodiment, the Coulomb force is preferably generated by applying a charge to the slip sheet 109 in a state where the glass plate 108 and the slip sheet 109 are in contact with each other as shown in FIG. As described above, the Coulomb force is generated by the ions generated by the corona discharge being applied to the interleaf paper 109. Adhesive force can be applied after the glass plate 108 and the interleaf paper 109 are laminated to form a glass plate laminate. In addition, you may prepare a glass plate laminated body in the state in which a main surface is parallel to the ground, and may provide Coulomb force. Moreover, you may give Coulomb force in the state which inclined the glass plate laminated body. When the sheet is applied in an inclined state, the interleaf sheet 109 is made of glass by a support device (not shown) or the like until a sufficient coulomb force is applied before the interleaf sheet 109 drops or a sufficient coulomb force can be applied. You may support in the vicinity of the board 108.

In this embodiment, the distance between the electrode 501 and the slip sheet 109 is preferably 10 mm or more. The electrode 501 can suppress damage to the slip sheet. The distance between the electrode 501 and the slip sheet 109 is preferably 100 mm or less. Coulomb force can be applied efficiently in a short time.

In this embodiment, the time for bringing the electrode 501 closer to the interleaf 109, that is, the time for applying the Coulomb force is preferably 1 second or more. Sufficient coulomb force can be applied to suppress the movement of the slip. The time for bringing the electrode 501 closer to the interleaf 109 is preferably 30 seconds or less. The electrode 501 can suppress damage to the slip sheet.

The glass laminate is placed on the pallet 105 while the Coulomb force is generated between the glass plate 108 and the interleaf 109 or within 60 seconds after the generation. Is preferred. Since the Coulomb force attenuates with time, the movement of the slip sheet 109 can be more stably suppressed by placing the Coulomb force within the above conditions. Further, various glass plates can be conveyed, for example, by changing the posture of the glass from horizontal to oblique within 60 seconds.

Here, “in the middle of generating the Coulomb force” is, for example, in the middle of supplying the electric charge from the source of the Coulomb force. For example, the electrode 501 is close to the slip sheet 109. Further, “after generation is completed” is, for example, a point in time when electric charge is no longer supplied from a coulomb force generation source. For example, the electrode 501 is away from the interleaf 109.

Placement of the glass laminate on the pallet 105 is preferably within 45 seconds, more preferably within 30 seconds, still more preferably within 15 seconds, and even more preferably within 10 seconds after the generation of the Coulomb force. It is preferable. The movement of the slip sheet 109 can be suppressed more stably.

Also, it is preferable that the Coulomb force forms a distribution in the glass plate surface. If the entire surface is uniformly charged and overcharged, a repulsive force may be generated, which may cause the slip sheet 109 to be bent, and can be prevented. By providing the distribution of the charge amount in the surface of the glass plate, even when the charge is excessive in a certain region, the charge amount can be attenuated in the surface toward the sparse region.

Moreover, it is preferable that the region where the Coulomb force is generated changes over time. Overcharging can be prevented by not charging the same region. The region where the Coulomb force is generated may be an enclave or may be formed continuously.

In this embodiment, corona discharge is used as an example. However, any method may be used as long as a Coulomb force can be applied.

(Example of glass plate package)
FIG. 6 is a view showing a glass plate package manufactured in one embodiment of the present invention. The glass plate package includes a plurality of alternately laminated glass plates 108 and a plurality of slip sheets 109, and the plurality of slip sheets 109 includes a specific slip sheet 109B. 109B has fewer wrinkles than the other interleaf paper 109A.

The specific slip sheet 109B is a slip sheet attached to the glass plate 108 by the methods exemplified in the various embodiments of the present invention. Therefore, the specific slip sheet 109B is less likely to wrinkle than the other slip sheet 109A, and fewer wrinkles are formed. Thereby, a glass plate can be made harder to be damaged. Moreover, the thickness of the glass plate laminated body 301 can be reduced, and the loading amount of the glass plate 108 on the pallet 105 can be increased.

For example, a small amount of wrinkles is formed by binarizing an image photographed through a glass plate in a state in which a specific interleaf 109 is sandwiched between two glass plates (for example, a wrinkle portion is reduced). Black, flat areas such as white), and the ratio of black to white can be evaluated. If it is the specific interleaving paper 109B manufactured by one Embodiment of this invention, it can be 0.01 or less, for example.

Also, the specific slip sheet 109B has a wrinkle occurrence location. For example, wrinkles can be particularly reduced at locations where the glass plate 108 and the interleaf paper 109 are attached by Coulomb force. By controlling the bias of such wrinkles, the glass plate can be made more difficult to break. Moreover, the thickness of the glass plate laminated body 301 can be reduced, and the loading amount of the glass plate 108 on the pallet 105 can be increased. The part where the generation of wrinkles is particularly small is, for example, a part attached to the peripheral part of the glass plate 108 or a part attached to the glass plate 108 in the corner part of the slip sheet.

Further, the specific interleaving paper 109B is present at an arbitrary period counting from the interleaving paper forming the outermost surface of the glass plate laminate 301. This occurs when only the pair of the uppermost glass plate 108 and the slip sheet 109 is attached when the glass plate laminate 301 is placed on a pallet for each batch as in the modification. By doing in this way, when unpacking a glass plate package, it can become a standard of the quantity at the time of handling the glass plate 108.

In addition, in FIG. 6, although the glass plate package produced by the modification of 1st Embodiment of this invention was illustrated, it is not limited to this. Any of 1st, 2nd, 3rd embodiment may be sufficient, and any modification may be sufficient and it may be created by another embodiment recalled from them.

Note that the material of the specific interleaf 109B and the other interleaf 109A is preferably the same. There is no need to use both separately, and the production of the glass plate package is simplified.

Note that the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like can be made as appropriate. In addition, the material, shape, dimension, numerical value, form, number, location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

In the present specification, the adhesion between the glass sheet and the slip sheet may be such that the slip sheet and the glass sheet are not displaced at least until they are placed on the pallet. For example, it is sufficient if the glass plate is placed on a pallet in a horizontal state and can withstand shearing force due to wind, and when the glass plate is inclined or perpendicular to a horizontal plane, the paper does not fall by its own weight. Although it does not specifically limit as a specific value, It is preferable in it being 0.1 N / m < ² > or more when the tensile shearing adhesive strength according to JISK6850 is applied to a glass plate and a slip sheet. .

Also, the adhesion between the glass plate and the slip sheet may be temporary. That is, the attachment may be released after the attached glass plate and the slip sheet are placed on the pallet.

Further, a pair of a glass plate and a slip sheet (hereinafter also referred to as a first pair) is placed on the pallet in a state of being attached, and a pair of the next glass plate and the slip sheet (hereinafter also referred to as a second pair). Until the first pair is stacked on the first pair, the first pair may remain attached. Since the movement of the first pair of slip sheets can be suppressed until the second pair is placed, a glass plate package in which the glass plate is not easily damaged can be manufactured.

In addition, when the adhesion of the first pair is attenuated after the first pair is placed on the pallet with the first pair attached and before the second pair is stacked on the first pair, You may give adhesive force to a pair again. As an implementation method, for example, a method as in the third embodiment can be mentioned. Since the movement of the first pair of slip sheets can be suppressed until the second pair is placed, a glass plate package in which the glass plate is not easily damaged can be manufactured.

This application claims priority based on Japanese Patent Application No. 2017-105585 filed with the Japan Patent Office on May 29, 2017. The entire contents of Japanese Patent Application No. 2017-105585 are incorporated herein by reference. .
