Description
Technical Field
The present invention relates to a glass plate laminate and a glass plate package body having a sheet interposed between glass plates.
Background
For a glass substrate of a display such as a liquid crystal display or an organic EL (Electro-Luminescence) display, a glass plate having a thickness as thin as, for example, 0.05 to 0.7mm is used. In recent years, the size of the glass substrate for a display glass substrate has been increased, and for example, the size of the 7 th generation glass plate is 1870mm × 2200mm.
In order to transport or store such glass plates for a glass substrate for a display in a state of being stacked vertically, a dedicated tray for packing glass plates is used for packing (for example, japanese patent laid-open No. 2016-033030). The glass sheets are loaded on the glass sheet packaging tray by, for example, a robot while sandwiching the interleaving paper. After the loading, the glass plate is packed and fixed to the back panel. Thereafter, the glass sheets are conveyed for each glass sheet packaging tray.
SUMMERY OF THE UTILITY MODEL
[ problem to be solved by the utility model ]
The glass plate for a glass substrate for a display is manufactured by, for example, a down-draw method. In the down-draw method, a glass ribbon formed by drawing molten glass in a downward direction is cut into pieces of a predetermined length, and the end portions in the width direction to be thick are further cut off to produce glass plates. The glass sheet thus produced has a substantially constant sheet thickness in a region (central portion) including the center in the width direction orthogonal to the drawing direction, whereas the sheet thickness gradually increases from the central portion side toward the end side in the width direction in regions (both end portions) including both ends in the width direction.
When glass plates having such a plate thickness distribution are stacked upright on a glass plate packaging tray so that the width direction is the vertical direction, the upper portion of the upright glass plate may be separated from the rear surface plate of the tray and bent so as to be inclined forward due to the weight of the end portion having a large plate thickness located above the glass plate, as compared with the case where the glass plate is erected so that the width direction is the horizontal direction. In particular, when the number of stacked glass sheets is large, the glass sheets may be greatly bent to be inclined toward the front of the tray, and as a result, the glass sheets may be broken. The chips or dusts of the glass sheet generated by the breakage may damage other glass sheets or adhere to the surface to contaminate them. In this way, while the damaged glass sheet or the contaminated glass sheet is removed from the laminated body or the contamination cause such as the chips or the dusts is removed from the surrounding environment, the production of the glass sheet has to be stopped, and the productivity of the glass sheet is greatly reduced. That is, a significant cost is incurred by breakage of the glass sheets in the laminated body. In addition, a lot of glass plates in which a specific number of loading pieces cannot be secured is generated, and the production efficiency is significantly impaired. Further, when the glass plate tilted forward as described above is conveyed, the posture of the glass plate during conveyance becomes unstable, and there is a problem that breakage, damage, or the like of the glass plate is induced.
The utility model aims to provide a glass plate lamination body and a glass plate package body which can really restrain the bending of glass plates vertically laminated on a tray and prevent the damage of the glass plates.

The tray 1 is configured as described above, but the tray 1 is not limited to the above configuration.
(glass plate laminate)
Fig. 3 shows a glass plate laminate 50.
The glass plate laminate 50 includes a plurality of rectangular glass plates 10 and a plurality of rectangular sheet bodies 60. In fig. 1, the sheet body 60 is not shown.
The plurality of glass plates 10 are rectangular plate bodies arranged to overlap each other. The glass plate 10 is used as a glass substrate for a Flat Panel Display (FPD) such as a liquid crystal Display and an organic EL Display.
The glass plate 10 is made of borosilicate glass, aluminosilicate glass, aluminoborosilicate glass, soda lime glass, alkali silicate glass, alkali aluminosilicate glass, alkali aluminogermanate glass, or the like. As the glass plate of the glass substrate for liquid crystal displays or the glass substrate for organic EL displays, a glass plate containing substantially no alkali or containing only a slight amount of alkali is preferably used. One surface of the glass plate 10 for a liquid crystal display is a smooth surface on which a thin film such as a semiconductor element array or a color filter is formed, and the other surface is a smooth surface on which a polarizing filter is formed.
The glass plate 10 has a composition shown below, for example. The numerical values shown in parentheses below are preferred composition ratios. The following composition ratios% represent mass%.
SiO 2 :50～70％(57～64％)，
Al 2 O 3 ：5～25％(12～18％)，
B 2 O 3 ：0～15％(6～13％)。
The composition shown below may be included as desired.
MgO：0～10％(0.5～4％)，
CaO：0～20％(3～7％)，
SrO:0 to 20% (0.5 to 8%, more preferably 3 to 7%),
BaO:0 to 10% (0 to 3%, more preferably 0 to 1%),
ZrO 2 :0 to 10% (0 to 4%, more preferably 0 to 1%).
In addition, in the above composition, it is particularly preferable to contain SiO 2 ：50～70％、B 2 O 3 ：5～18％、Al 2 O 3 : 10 to 25%, mgO:0 to 10%, caO:0 to 20%, srO:0 to 20%, baO:0 to 10%, RO:5 to 20% (however, R is at least 1 selected from Mg, ca, sr and Ba).
Further, more preferably R' 2 O:0.20% to 2.0% (provided that R' is at least 1 selected from Li, na and K).
It is preferable that the total content of the clarifying agent is 0.05 to 1.5% and that substantially no As is contained 2 O 3 、Sb 2 O 3 And PbO. Here, substantially not containing means less than 0.01% by mass, and not intentionally containing other than impurities.
The content of iron oxide in the glass is preferably 0.01 to 0.2%.
Fig. 4 is a diagram illustrating the distribution of the thickness of the glass sheet 10. In fig. 4, the thickness distribution in the width direction of the glass sheet 10 is shown by thick solid lines so as to correspond to the position in the width direction of the glass sheet 10 in plan view, overlapping the glass sheet 10 in plan view. The thickness of the plate is indicated by the height of the thick solid line.
As shown in fig. 4, the thickness of both end portions 10s in a direction parallel to the bottom side of the glass plate 10 standing and leaning on the tray 1 (hereinafter, referred to as the width direction) is thicker than the thickness of the central portion 10c between the both end portions 10 s. The glass sheet 10 having such a sheet thickness distribution is a glass sheet produced by a down-draw method such as the overflow down-draw method. In the down-draw method, a glass ribbon formed by drawing molten glass downward is cut into pieces of a predetermined length, and the end portions in the width direction to be thick are further cut off to produce glass sheets 10. As shown in fig. 4, the glass sheet 10 thus produced has a substantially constant sheet thickness in a central portion 10c including the center in the width direction X perpendicular to the drawing direction Y during forming, whereas the sheet thickness gradually increases from the central portion 10c side toward the end side in the width direction X in both end portions 10s including both ends in the width direction. For example, the thickness of the central portion 10c is 0.1 to 1.5mm, the upper limit value of the thickness is preferably 1.1mm, 0.7mm, or 0.5mm, and the upper limit value of the thickness is most preferably 0.4mm. The lower limit of the preferred thickness is 0.2mm. On the other hand, the maximum thickness of the both end portions 10s is 0.1 to 1.8mm, and the upper limit values of the maximum thickness are preferably 1.5mm, 0.9mm, and 0.65mm.
In the present specification, the both end portions 10s mean portions extending from each of both ends in the width direction X of the glass sheet 10 to a length area Ws of, for example, 3 to 5% of the width (length in the width direction) of the glass sheet 10, and the central portion 10c means a portion of the width area Wc of the glass sheet 10 connected to the both end portions 10 s.
If glass plates having such a plate thickness distribution are stacked upright on the tray 1 so that the width direction X is the vertical direction, the upper portion of the upright glass plate may be bent so as to be inclined forward away from the rear panel 21 of the tray 1 due to the weight of the thick plate thickness end portion located above the glass plate, as compared with the case where the glass plate is upright so that the width direction X is the horizontal direction. In particular, when the number of laminated glass sheets is large, the glass sheets may be largely bent due to a large forward inclination of the glass sheets, and as a result, the glass sheets may be broken. The glass sheet fragments or dust generated by the breakage may damage other glass sheets or adhere to the surface to contaminate them. In this way, while the damaged glass sheet or the contaminated glass sheet is removed from the laminated body or the contamination cause such as the chips or the dusts is removed from the surrounding environment, the production of the glass sheet has to be stopped, and the productivity of the glass sheet is greatly reduced. That is, a large cost is generated by breakage of the glass sheets in the laminated body. In addition, a lot of glass plates in which a specific number of loading pieces cannot be secured is generated, and the production efficiency is significantly impaired. Further, when the forward-tilted glass sheet is conveyed, the posture of the glass sheet during conveyance becomes unstable, and there is a problem that breakage, damage, or the like of the glass sheet is induced. In the glass plate package 100 of the present embodiment, as described above, the plate thickness of the both end portions 10s in the width direction X of the glass plate 10 is thicker than the plate thickness of the central portion 10c, in other words, by erecting the glass plate 10 so that the width direction X becomes the horizontal direction, the weight of the upper end portion positioned on the upper side of the glass plate 10 is reduced as compared with the case of erecting so that the width direction X becomes the vertical direction, and the upper portion of the erected glass plate 10 is suppressed from being tilted forward and bent so as to be separated from the back panel 21 of the tray 1.
The sheet body 60 is disposed so as to be interposed at least 1 between the glass plates 10. The sheet body 60 is a sheet for protecting the glass plates 10 by preventing the glass plates 10 from directly contacting each other. The sheet body 60 is configured to suppress damage to the surface of the glass plate 10 caused by rubbing against the surface of the glass plate 10. In the glass plate laminate 50 illustrated in fig. 3, the glass plates 10 and the sheet members 60 are alternately laminated one by one, but the sheet members 60 may be arranged in 2 or 3 or more pieces between the glass plates 10 adjacent to each other in the laminating direction.
The at least 1 sheet body interposed between the glass plates 10 includes a liner paper 61 obtained by papermaking of a raw material containing pulp fibers. The sheet body 60 illustrated in fig. 3 is a mount 61. The interleaving paper 61 prevents the surface of the glass plate 10 from being contaminated by organic substances and the like present in the atmosphere during storage and transportation of the glass plate 10 adhering to the surface of the glass plate 10. The surface of the interleaving paper 61 has a certain degree of roughness in order to prevent the resin and the like contained in the interleaving paper 61 from adhering to the surface of the glass plate 10.
Fig. 5 is a diagram illustrating a relationship between the laminated glass plates 10 and the interleaving paper 61.
The interleaving paper 61 is disposed so that the paper-making direction P of the interleaving paper 61 is orthogonal to the bottom side of the glass sheet 10, that is, so that the paper-making direction of the interleaving paper 61 coincides with the stretching direction Y of the glass sheet 10. As described above, in the glass plate package 100, the forward tilting and bending of the glass plate 10 are suppressed by the thickness of the both end portions 10s in the width direction X of the glass plate 10 being thicker than the thickness of the central portion 10 c. On the other hand, the interleaving paper 61 is generally produced by pulling out a specific length region from a long sheet 61A (see fig. 6) wound in a roll shape in the paper-making direction P and cutting the sheet. Therefore, the interleaving paper 61 extending in a planar shape generates a force to form a roll shape in the paper-making direction P, and when the force is applied between the glass plates 10, the force acts on the glass plates 10. At this time, in the glass pane laminate, when the paper-making direction of the interleaving paper coincides with the width direction X of the glass pane 10, the force generated by the interleaving paper 61 acts as a force assisting the both end portions 10s of the glass pane 10 to separate from the back panel 21 of the tray 1, and the glass pane 10 may bend. In the present embodiment, since the interleaving paper 61 is disposed so that the paper-feeding direction P is orthogonal to the bottom side of the glass sheet 10 as described above, the force of the glass sheet 10 tending to bend is cancelled by the force generated by the interleaving paper 61, and the bending of the glass sheet 10 can be reliably suppressed. This prevents the glass plate 10 from being damaged.
Further, since the tear strength of the paper having the paper-making direction in the paper-making direction is weak compared to the direction orthogonal to the paper-making direction, the paper-making direction of the interleaving paper 61 can be specified by tearing the interleaving paper 61 in each of the directions parallel to two sides orthogonal to the four sides, for example.
The thickness of the liner paper 61 is preferably 0.05 to 0.2mm from the viewpoint of securing a force to form a roll shape in the paper-making direction P.
To protect the glass sheets 10, the interleaving paper 61 has a size larger than that of the glass sheets 10. The base sheet 61 is laminated so as to form a protruding portion protruding from the upper side and both side edges of the glass plate 10. Among them, regarding the protruding portions 61a of the backing paper 61 which protrude upward from the upper side of the glass plate 10, the length of the protruding portions 61a, that is, from the upper side of the glass plate 10 to the upper side of the protruding portions 61d is 90mm or less, preferably 40 to 80mm. In the protruding portions 61b and 61c of the base sheet 61 protruding from both sides of the glass sheet 10 and protruding to the sides, the length of the protruding portions 61b and 61c, that is, the length from the side edge of the glass sheet 10 to the side edges of the protruding portions 61b and 61c is 70mm or less, preferably 10 to 50mm.
The glass plate laminate 50 is placed on the tray 1 in a state where the glass plate 10 is standing up against the tray 1. The process of forming the glass plate laminate 50 on the pallet 1 will be specifically described. First, 1 slip sheet 61 is set up against the tray 1 on which nothing is placed. The backing paper 61 that is standing up and leaning against is in close contact with the front surface of the back panel 21. Next, 1 glass plate 10 was set up against the tray 1. The glass sheet 10 which is standing up is in close contact with the interleaving paper 61 which was standing up. Next, 1 slip sheet 61 is stood up against the tray 1. The operation is repeated to alternately stand glass sheets 10 and interleaving papers 61 against the tray 1, thereby forming a glass sheet laminate 50. The number of glass sheets 10 of the glass sheet laminate 50 mounted on the tray 1 is, for example, about 500 in the case of a 5 th generation glass substrate having a central portion 10c with a thickness of 0.5mm, and about 350 in the case of a 5 th generation glass substrate having a central portion 10c with a thickness of 0.7 mm. The glass plate laminate 50 placed on the tray 1 is stored and transported as the glass plate package 100 in a state of being fixed to the tray 1 by using a belt or the like locked to the tray 1.
After the glass plate laminate 50 mounted on the tray 1 is stored and transported as the glass plate package 100, the glass plate 10 is taken out while removing the interleaving paper 61 in a display manufacturing line or the like. At this time, the glass sheets 10 and the interleaving paper 61 are alternately taken out from the glass sheet laminate 50 on the tray 1 in the reverse order of the stacking order. The mount 61 is configured such that the projections 61a are sucked at a plurality of points by a suction device (not shown) extending in a horizontal bar shape and provided with a plurality of suction nozzles, for example, along the width direction W of the glass plate 10. Thereby, the mount 61a is held to take out the mount 61 from the glass plate laminate 50.
According to the glass plate laminate 50 described above, when the glass plate laminate is stood on the tray 1, the glass plate 10 stood on the tray 1 can be surely prevented from being bent, and the glass plate 10 can be prevented from being damaged.
Normally, the glass plate 10 stands and leans on the tray 1 in a posture in which the longitudinal direction is horizontal. The glass plate 10 has dimensions of, for example, 500 to 250mm in the short-side direction and 2500 to 3500mm in the long-side direction. On the other hand, in the glass plate package 100 of the present embodiment, as described above, since the bending of the glass plates 10 stacked upright on the tray 1 can be reliably suppressed, the glass plates 10 can be also stood on the tray 1 in a posture in which the longitudinal direction is vertical.
According to one embodiment, in the glass plate package 100, the backing paper 61 is preferably disposed so that the major surface on the outer peripheral side of the long sheet 61A wound in a roll shape in the paper-making direction P out of the major surfaces on both sides of the backing paper 61 faces forward. In the glass plate package 100, if the interleaving paper 61 is disposed in the sheet 61A such that the main surface facing the outer peripheral side faces rearward, the force generated by the interleaving paper 61 acts strongly forward at both the upper and lower ends of the glass plate 10, and therefore, when the thickness of both the ends 10s of the glass plate 10 is small, the upper portion of the glass plate 10 may be inclined forward or bent.
According to one embodiment, it is preferable that at least 1 of the sheet bodies 60 further include a resin film (not shown). That is, it is preferable that a film is interposed between the glass plates 10 in addition to the interleaving paper 61. This can improve the protective effect of the glass sheet 10 in the glass sheet laminate 50 having a large size and a large number of laminated glass sheets 10. The film is preferably disposed on both sides of the mount 61. Examples of the material of the film include resins such as thermoplastic polyurethane, polyethylene, polybutylene, polyamide, polypropylene, polystyrene, fluororesin, polycarbonate, and polyvinyl chloride. The film may be a sheet made of a foamed resin such as polyethylene, polypropylene, polystyrene, urethane, or a propylene-ethylene copolymer.
Although the glass plate package and the glass plate laminate have been described in detail above, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the scope of the present invention.
