Description

The present invention relates to a method for manufacturing 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 do not come into direct contact with each other during storage, packing, or transfer to the next process. As described above, the interleaving paper is sandwiched between the adjacent glass plates to prevent scratches, breakage, and adhesion between the glass plates.

The step of laminating the interleaving paper on the glass plate surface when assembling such a glass plate package is, for example, the surface of the glass plate to be slanted against the diagonally vertically stacked pallet, or the flat placement on the flat pallet from now on. This is done by stacking the interleaving paper on the surface of the glass plate to be tried.

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

(First Embodiment)
FIG. 1 is a diagram showing a method for manufacturing a glass plate package according to the first embodiment of the present invention. FIG. 1 shows a glass plate handling having a suction pad 106 at the tip of a diagonally vertically placed type pallet 105 composed of a base portion 101, a back surface portion 102, an inclined pedestal portion 103, and an inclined backrest portion 104. The glass plate 108 is placed on the pallet 105 by the device 107.

Here, the glass plate 108 and the interleaving paper 109 are placed on the pallet 105 in a state of being adhered to each other. It is possible to prevent problems such as the interleaving paper 109 being laminated at a position deviated from the intended position, the interleaving paper 109 being laminated with wrinkles, and the interleaving paper 109 being laminated in a folded state. , It is possible to manufacture a glass plate package in which the glass plate is not easily damaged.

In the present embodiment, the glass plate 108 and the interleaving paper 109 are adhered to each other through the adhering material 110 between the glass plate 108 and the interleaving paper 109. The glass plate 108 and the interleaving paper 109 can be firmly adhered to each other through the adhesive material 110.

The adhesive material 110 preferably has a 180 ° peeling adhesive force defined by JIS Z 0237 of 10 N / 25 mm or more and 20 N / 25 mm or less. The interleaving paper 109 can be attached to such an extent that it cannot move freely, and the interleaving paper 109 can be easily peeled off from the glass plate 108 at the time of unpacking.

Further, the adhesive material 110 preferably has an interaction distance of the Hansen solubility parameter (also referred to as HSP) with water at 25 ° C. of 17 or less. Since the adhering material 110 is easily dissolved in water, it is easy to remove the adhering material 110 remaining on the surface of the glass plate 108 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 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 expressed 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 with water δ _D1 : Dispersion force term δ _P1 : of Hansen solubility parameter of additive Dipole intermolecular force term δ _H1 : Additive Of the Hansen solubility parameters, the hydrogen bond force term

The Hansen solubility parameter is the solubility parameter introduced by Hildebrand, which Hansen divides into three components, the dispersion term δ _D , the polar term δ _P , and the hydrogen bond term δ _H , and shows them in a three-dimensional space. It is a thing. The dispersion term δ _D indicates the effect of the dispersion force, the polar term δ _P indicates the effect of the dipole interpole force, and the hydrogen bond term δ _H indicates the effect of the hydrogen bond force. The closer the coordinates of a specific substance X and the coordinates of a certain solvent in the three-dimensional space are, the easier it is for the substance X to dissolve in the solvent. Details of the definition and calculation method of the Hansen solubility parameter are described in the following documents; Hansen, "Hansen Solubility Parameters: A Users Handbook", CRC Press, 2007.

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

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

FIG. 2 is a view of the glass plate 108, the interleaving paper 109, and the adhering material 110 from the direction from the tip of the arrow toward the root in the Y direction in the state of FIG. 1 (the glass plate handling device 107 is not used). Illustrated).

It is preferable that the glass plate 108 and the interleaving paper 109 are adhered to each other in the peripheral region of the glass plate 108 as shown in FIG. Specifically, the adhering material 110 is arranged in the peripheral region of the glass plate 108, and the glass plate 108 and the interleaving paper 109 are adhered to each other. The glass plate 108 and the interleaving paper 109 may be attached only in the peripheral region. Since the peripheral region is removed in the process of becoming the final product or is difficult to be visually recognized in the final product, it is not necessary to excessively consider the residue of the adhering material 110 on the glass plate 108. In other words, the influence of the residual adhesive material 110 on the glass surface can be minimized.

Here, the "peripheral region" refers to a region occupying a width of 20 mm inward from the contour line of the glass plate 108 in a plan view from the plate thickness direction of the glass plate 108, for example. In FIG. 2, it refers to a region surrounded by the outline of the glass plate 108 and the broken line 201.

In FIG. 2, the adhering material 110 is arranged as a jumping ground 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 interleaving paper 109 is attached to the glass plate 108. Since the corner portion of the interleaving paper 109 is particularly liable to shake, it is possible to more effectively suppress problems such as the interleaving paper 109 being turned over and the interleaving paper 109 being laminated in a folded state.

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

Further, the adhesion between the glass plate 108 and the interleaving paper 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 with the main surface parallel to the ground, the adhering material 110 is placed on the main surface of the glass plate 108, the interleaving paper 109 is laminated on the glass plate 108, and the glass plate 108-adhesive material 110 is laminated. -A laminated body of the interleaving paper 109 may be formed and then laminated on the pallet 105 using the glass plate handling device 107. At this time, the glass plate handling device 107 may directly hold the glass plate 108 by the suction pad 106, and after considering the air permeability of the interleaving paper 109, adsorbs the glass plate 108 through the interleaving paper 109. It may be held by the pad 106. When the glass plate 108 and the interleaving paper 109 are adhered in this way, in the present embodiment, since the pallet 105 is a diagonal vertical installation type, the glass plate 108 has a main surface from a state where the main surface is parallel to the ground. Changes its posture so that it is tilted with respect to the ground. As described above, in the present embodiment, it is possible to include a step of changing the posture of the glass plate 108 in the process of placing the glass plate 108 on the pallet from the state where the glass plate 108 is attached to the interleaving paper 109. A wider variety of glass plates can be transported until the placement on the pallet is completed.

This embodiment is suitably used for a rectangular interleaving paper 109 having a side size of 800 mm or more. If the size of one side of the interleaving paper 109 is 800 mm or more, it is easy to shake when placed on the pallet due to 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.

Although the present embodiment shows the form of diagonally vertically stacked pallets, the present embodiment is not limited to this. It can also be used for flat pallets. The conceptual diagram is shown in FIG. In the case of a flat stacking pallet, for example, a glass plate 108 is prepared with the main surface parallel to the ground, an adhering material 110 is placed on the main surface of the glass plate 108, and the interleaving paper 109 is laminated on the glass plate 108. A laminate of the plate 108-adhesive material 110-insertion paper 109 is formed, and then the glass plate 108 is held by the suction pad 106 via the interleaving paper 109 and placed on a pallet using the glass plate handling device 107. In this case, the movement of the interleaving paper 109 is suppressed to some extent by the suction pad 106, but the interleaving paper 109 in the portion where the suction pad 106 does not exist may move due to the wind during glass transportation or the vibration during placement. rice field. According to this embodiment, the movement of the interleaving paper 109 can be suppressed. In particular, it is possible to suppress the movement of the peripheral portion and the corner portion of the interleaving paper.

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

In addition, in FIGS. 1 and 7, the thickness of the adhering material 110 is intentionally described as thick for easy understanding, but the thickness of the adhering material 110 is compared with the glass plate 108 and the interleaving paper 109. It may be extremely thin. Therefore, in FIG. 7, the glass plate 108 is held by suction with the suction pad 106.

(Modification example)
FIG. 3 is a diagram showing a modified example of the first embodiment of the present invention. First, in (a), a glass plate laminate 301 composed of 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 interleaving paper 109 may be laminated in advance at another place, and the glass plate laminate 301 may be conveyed to the front of the pallet 105. Alternatively, the glass plate 108 and the interleaving paper 109 may be laminated in front of the pallet 105 to form the glass plate laminate 301. Further, in the case of this modification, only the uppermost pair of the glass plate laminate 301 may be bonded to the glass plate 108 and the interleaving paper 109 via the adhesive material 110. This is because the lower glass plate 108 and the interleaving paper 109 of the uppermost pair make it difficult for the interleaving paper to move when placed due to the weight of the uppermost pair. Alternatively, all the pairs of the glass plate 108 and the interleaving paper 109 may be attached by the adhering material 110.

Next, as shown in (b), a part of the conveyor 303 is movable in a state where the glass plate laminated body 301 is in contact with the receiving plate 302. A part of the conveyor 303 operates as shown by the arrow in (b) so that the glass plate laminate 301 rises at an angle with respect to the horizontal plane (XY plane).

Then, as shown in (c), the glass plate laminate 301 is placed on the pallet 105 so as to collapse, and a part of the conveyor 303 returns to its original position until a sufficient amount is loaded on the pallet 105. (A)-(c) are repeated.

In the modified configuration, the glass plate 108 and the interleaving paper 109 can be processed for each batch without being placed on the pallet 105 one by one, so that efficient placement is possible.

Further, since only the uppermost pair of the glass plate laminate 301 can be attached, the productivity is improved as compared with the state where all the pairs are attached.

The present modification is not limited to the first embodiment. It can also be suitably used as a modification of the second embodiment and the third embodiment.

(Second Embodiment)
FIG. 4 is a diagram showing a method for manufacturing a glass plate package according to a second embodiment of the present invention. Those having the same configuration as that of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted. Further, the description regarding the attached range, interpretation of terms, modification, etc. shall be the same as in the first embodiment unless otherwise specified.

In the second embodiment, the glass plate 108 and the interleaving paper 109 are adhered to each other through water between the glass plate 108 and the interleaving paper 109. The glass plate 108 and the interleaving paper 109 can be temporarily adhered to each other through moisture.

Moisture may be, for example, sprayed with a liquid, and may be impregnated into the interleaving paper 109. Specific examples of the liquid used as water include pure water and alcohol. It is preferable that the glass plate 108 and the interleaving paper 109 are not affected, and that the foreign matter contained in the interleaving paper 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.

Further, the liquid used as water preferably has volatility at room temperature (for example, 20 degrees). If the glass plate 108 and the interleaving paper 109 are adhered only until the glass plate laminate is placed on the pallet 105, and then volatilized, the surface quality of the glass plate 108 even if the entire surface of the glass plate 108 is adhered. The effect on can be reduced.

Further, 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 interleaving paper 109, the glass plate 108 and the interleaving paper 109 are brought into contact with each other and adhered to each other. By spraying, the glass plate 108 and the interleaving paper 109 can be uniformly adhered to each other, and it is possible to prevent both of them from excessively containing water. For example, the glass plate 108 is prepared with the main surface parallel to the ground, the liquid is sprayed toward the upper surface of the glass plate 108 with a spray device, the interleaving paper 109 is laminated on the glass plate 108, and the glass plate 108-adhesive material is laminated. A laminated body of 110-blanket 109 may be formed and then laminated on the pallet 105 using the glass plate handling device 107. The liquid may be sprayed on the interleaving paper 109 side by the spraying device.

(Third Embodiment)
FIG. 5 is a diagram showing a method for manufacturing a glass plate package according to a third embodiment of the present invention. Those having the same configuration as that of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted. Further, the description regarding the attached range, interpretation of terms, modification, etc. shall be the same as in the first embodiment unless otherwise specified.

In the third embodiment, the adhesion between the glass plate 108 and the interleaving paper 109 is performed by generating a Coulomb force between the glass plate 108 and the interleaving paper 109. By utilizing the Coulomb force, the glass plate 108 and the interleaving paper 109 can be temporarily adhered to each other. Further, 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 acting between charged particles, and what is used in this embodiment is an attractive force acting between charges of different codes among the Coulomb forces.

In FIG. 5, the electrode 501 having a voltage having an absolute value of 10 kV or more is brought close to the glass plate 108 and / or the interleaving paper 109 to generate a Coulomb force between the glass plate 108 and the interleaving paper 109. When 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 chargeability of the glass plate 108 and the interleaving paper 109. As a result, of the positive ions and negative ions generated when the corona discharge occurs, the negative ions are attracted to the electrode side, and the positive ions are likely to be imparted 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 interleaving paper 109, it is preferable that the electrode 501 has a negative voltage in consideration of the chargeability of the glass plate 108 and the interleaving paper 109. As a result, of the positive ions and negative ions generated when the corona discharge occurs, the positive ions are attracted to the electrode side, and the negative ions are likely to be imparted to the interleaving paper 109. As a result, the Coulomb force can be efficiently applied.

The absolute value of the voltage possessed by the electrode 501 is preferably 15 kV or more, more preferably 20 kV or more, still more preferably 25 kV or more, still more 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 interleaving paper 109.

In the present embodiment, the Coulomb force is preferably generated by applying an electric charge to the interleaving paper 109 in a state where the glass plate 108 and the interleaving paper 109 are in contact with each other as shown in FIG. As described above, the Coulomb force is generated by applying the ions generated by the corona discharge to the interleaving paper 109. Adhesive force can be applied after the glass plate 108 and the interleaving paper 109 are laminated to form a glass plate laminate. The glass plate laminate may be prepared in a state where the main surface is parallel to the ground, and a Coulomb force may be applied. Further, the Coulomb force may be applied in a state where the glass plate laminate is tilted. When applying in an inclined state, apply a sufficient Coulomb force before the interleaving paper 109 falls, or apply a sufficient Coulomb force to the glass by a support device (not shown) until a sufficient Coulomb force can be applied. It may be supported in the vicinity of the plate 108.

In the present embodiment, the distance between the electrode 501 and the interleaving paper 109 is preferably 10 mm or more. The electrode 501 can prevent damage to the interleaving paper. Further, the distance between the electrode 501 and the interleaving paper 109 is preferably 100 mm or less. Coulomb force can be applied efficiently in a short time.

In the present embodiment, the time for bringing the electrode 501 closer to the interleaving paper 109, that is, the time for applying the Coulomb force is preferably 1 second or longer. Sufficient Coulomb force can be applied to suppress the movement of the interleaving paper. Further, the time for bringing the electrode 501 close to the interleaving paper 109 is preferably 30 seconds or less. The electrode 501 can prevent damage to the interleaving paper.

Further, the glass laminate is placed on the pallet 105 while the Coulomb force is being generated between the glass plate 108 and the interleaving paper 109, or within 60 seconds after the generation is completed. Is preferable. Since the Coulomb force attenuates with time, the movement of the interleaving paper 109 can be suppressed more stably by placing the paper under the above conditions. In addition, a wider variety of glass plates can be transported, for example, by changing the posture of the glass from horizontal to diagonal within 60 seconds.

Here, "in the process of generating Coulomb force" means, for example, in the process of supplying electric charge from a source of Coulomb force. The state where the electrode 501 is brought close to the interleaving paper 109 and the like can be mentioned. Further, "after the generation is completed" is, for example, a time when the electric charge is no longer supplied from the source of the Coulomb force. Examples thereof include a state in which the electrode 501 is kept away from the interleaving paper 109.

The 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, still more preferably within 10 seconds after the Coulomb force has been generated. Is preferable. The movement of the interleaving paper 109 can be suppressed more stably.

Further, 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 interleaving paper 109 to bend, which can be prevented. By distributing the amount of charge in the glass plate surface, even if the amount of charge is excessively charged in a certain region, it can be attenuated in the surface toward the region where the amount of charge is sparse.

Further, it is preferable that the region where the Coulomb force is generated changes over time. Overcharging can be prevented by not continuing to charge the same area. The region where the Coulomb force is generated may be an excursion or may be continuously formed.

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

(Example of glass plate packaging)
FIG. 6 is a diagram showing a glass plate package manufactured according to an embodiment of the present invention. The glass plate packing body has a plurality of alternately laminated glass plates 108 and a plurality of interleaving sheets 109, and the plurality of interleaving sheets 109 have the specific interleaving paper 109B and the specific interleaving paper 109. 109B has less wrinkles than other interleaving papers 109A.

The specific interleaving paper 109B is an interleaving paper adhered to the glass plate 108 by the methods exemplified in various embodiments of the present invention. Therefore, the specific interleaving paper 109B is less likely to wrinkle than the other interleaving paper 109A, and the number of wrinkles formed is small. This makes it possible to make the glass plate less likely to be damaged. Further, the thickness of the glass plate laminate 301 can be reduced, and the load capacity of the glass plate 108 on the pallet 105 can be increased.

Less wrinkles are formed, for example, when the specific interleaving paper 109 is sandwiched between two glass plates, the image taken through the glass plates is binarized at a predetermined fighting value (for example, the wrinkles are formed). Black, flat areas are white, etc.) and can be evaluated by the ratio of black to white. The specific interleaving paper 109B manufactured in one embodiment of the present invention can be, for example, 0.01 or less.

Further, in the specific interleaving paper 109B, the wrinkles are unevenly generated. For example, wrinkles can be particularly reduced in the portion where the glass plate 108 and the interleaving paper 109 are adhered by the Coulomb force. By controlling such wrinkle bias, it is possible to make the glass plate less likely to be damaged. Further, the thickness of the glass plate laminate 301 can be reduced, and the load capacity of the glass plate 108 on the pallet 105 can be increased. The places where wrinkles are particularly small are, for example, the places where the glass plate 108 adheres to the peripheral edge portion, and the corner portions of the interleaving paper which adhere to the glass plate 108.

Further, the specific interleaving paper 109B exists at an arbitrary cycle counting from the interleaving paper forming the outermost surface of the glass plate laminated body 301. This occurs when only the pair of the uppermost glass plate 108 and the interleaving paper 109 is attached when the glass plate laminate 301 is placed on the pallet for each batch as in the modified example. By doing so, it is possible to use it as a guideline for the quantity when handling the glass plate 108, such as when unpacking the glass plate package.

Note that FIG. 6 illustrates the glass plate package created by the modification of the first embodiment of the present invention, but the present invention is not limited to this. It may be any of the first, second, and third embodiments, any modification, and may be created by another embodiment recalled from them.

It is preferable that the material of the specific interleaving paper 109B and the other interleaving paper 109A are the same. There is no need to use both properly, which simplifies the manufacture of glass plate packaging.

The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, and the like. In addition, the material, shape, size, numerical value, form, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary as long as the present invention can be achieved, and are not limited.

In this specification, the adhesion between the glass plate and the interleaving paper may be such that the interleaving paper and the glass plate do not shift at least until they are placed on the pallet. For example, it is sufficient that the glass plate can withstand the shearing force due to the wind when placed on the pallet in a horizontal state, and the paper does not fall due to its own weight when the glass plate is inclined or perpendicular to the horizontal plane. The specific value is not particularly limited, but is preferably 0.1 N / m ² or more when the tensile shear adhesive strength according to JIS K6850 is applied to the glass plate and the interleaving paper. ..

Further, the adhesion between the glass plate and the interleaving paper may be temporary. That is, the adhered glass plate and the interleaving paper may be released after being placed on the pallet.

Further, a pair of a certain glass plate and the interleaving paper (hereinafter, also referred to as the first pair) is placed on the pallet in a state of being attached, and the next pair of the glass plate and the interleaving paper (hereinafter, also referred to as the second pair) is placed on the pallet. ) May continue to adhere to the first pair until it is laminated on top of the first pair. Since the movement of the interleaving paper of the first pair can be suppressed until the second pair is placed, it is possible to manufacture a glass plate package in which the glass plate is not easily damaged.

Further, when the adhesive force 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 laminated on the first pair, the first pair is attached. Adhesion may be reapplied to the pair. Examples of the realization method include a method as in the third embodiment. Since the movement of the interleaving paper of the first pair can be suppressed until the second pair is placed, it is possible to manufacture a glass plate package in which the glass plate is not easily damaged.
