  Here, in the drawing, portions indicated by the same symbols are similar elements having similar functions. In addition, in the present specification, when a numerical range is expressed using “˜”, upper and lower numerical values indicated by “˜” are also included in the numerical range.

  Hereinafter, preferred embodiments of a glass sheet package according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 shows a glass plate for packing a glass plate laminate (hereinafter referred to as a “laminate”) 12 in which interleaving paper 10 and glass plates G are alternately arranged with a vertically stacked pallet (packing container) 14. 1 is an overall perspective view of a package (hereinafter referred to as “packaging”) 16. In addition, although the vertical pallet 14 was illustrated as a vertical packing container, it is not limited to this, The box which packs the laminated body 12 in the state of a horizontal stack may be sufficient. Here, packing means a state in which the laminate 12 (glass plate laminate) is placed on the pallet 14 (packaging container).

  As shown in FIG. 1, the pallet 14 includes a pedestal 18 serving as a base, a bottom receiving plate 20 on which a lower end surface of the glass plate G is placed, a triangular frame 22 in side view, and a surface (surface) of the glass plate G. Or a back support plate 24 on which the back surface is supported, a wall body 26, and the like.

  The bottom receiving plate 20 is provided on the mounting surface 28 provided on the upper surface of the base 18 so as to be inclined with respect to the mounting surface 28. The frame 22 is erected on the mounting surface 28. The inclined surface of the front surface of the frame 22 is set to 80 ° to 100 °, particularly preferably about 90 °, with respect to the main surface of the bottom receiving plate 20 (the surface on which the lower edge of the glass plate G is placed). . The back support plate 24 is stood and fixed to the inclined surface. In order to prevent damage to the bottom receiving plate 20 and the back receiving plate 24 due to contact with the glass plate G when the glass plate G is placed, a cushioning material (not shown) such as rubber or hard foamable resin. Is provided.

  A wall body 26 is erected on the rear portion of the mounting surface 28 of the base 18. The frame 22 is supported by the wall body 26. In addition, a pair of openings 30 for inserting and removing forklift claws (not shown) is provided on the front surface of the base 18.

  The bottom receiving plate 20 is inclined and placed on the mounting surface 28 via a plurality of triangular bottom pieces 32 disposed between the mounting surface 28 and the bottom receiving plate 20. Further, the bottom receiving plate 20 is arranged such that its main surface is inclined with respect to the mounting surface 28 of the pedestal 18 preferably at 5 ° to 25 °, more preferably 10 ° to 20 °, and particularly preferably about 18 °. The This facilitates the positioning operation of the glass plate G when the glass plate is loaded on the pallet 14 by the glass plate loading device (not shown). Further, since the main surface of each glass plate G is in contact with the main surface of the glass plate G on the back plate 24 side by its own weight, no useless gap is generated between the main surfaces of the glass plates G. Furthermore, the glass plate G to be placed can be stabilized, the glass plate G can be prevented from shifting or collapsing forward (in the direction opposite to the back plate 24), and scratches and cracks can be prevented.

  Moreover, it is preferable to insert and arrange a bag 36 filled with a desiccant into an opening formed by the bottom receiving plate 20, the mounting surface 28, and the bottom piece 32. As will be described later, the laminate 12 and the pallet 14 are packaged by a packaging bag (not shown). Water in the internal space of the packaging bag can be absorbed by the bag 36 filled with the desiccant. Thereby, since the humidity of laminated body 12 itself can be managed low, it can suppress that wrinkles generate | occur | produce in the interleaf paper 10. FIG.

  Note that the pallet 14 shown in FIG. 1 may be provided with lateral pressing members that restrict lateral displacement of the laminated body 12 at both ends in the longitudinal direction of the bottom receiving plate 20.

  The laminated body 12 is configured by alternately laminating a plurality of glass plates G and a plurality of interleaving papers 10 on the pallet 14. In the present embodiment, the interleaf paper 10 is a sheet arranged alternately with the glass plate, and corresponds to a spacer.

  The glass plate G is preferably used as a glass plate for a light guide plate. The glass plate G for a light guide plate has characteristics that it is superior in mechanical strength, hygroscopicity, and heat resistance to a resin light guide plate such as acrylic. The glass plate G for the light guide plate includes at least one end surface for entering light and a main surface for emitting incident light, and has high transmittance in the visible light region.

  The glass plate G is, for example, a rectangular plate-like body, and has two main surfaces facing each other and four end surfaces. The “rectangular shape” means a square shape or a rectangular shape, and includes a shape in which a corner portion is rounded. The glass plate G for the light guide plate is processed so that at least one end face (hereinafter also referred to as a light incident end face) of the four end faces has lower reflection and lower scattering than other end faces in order to enter light. For example, it is polished. The glass plate G for the light guide plate is configured to allow light incident from the light incident end surface to pass through the glass plate G and to be emitted from at least one main surface of the two main surfaces.

  In the glass plate G for the light guide plate, the minimum value of the internal transmittance in the wavelength range of 400 to 700 nm is 80% or more under the condition of the optical path length of 200 mm, and the difference between the maximum value and the minimum value of the internal transmittance is 15%. % Or less is preferable. The minimum value of the internal transmittance is 85% or more, and the difference between the maximum value and the minimum value of the internal transmittance is more preferably 13% or less. The minimum value of the internal transmittance is 90% or more, More preferably, the difference between the maximum value and the minimum value of the internal transmittance is 8% or less. The internal transmittance of the glass plate G can be measured using an ultraviolet-visible near-infrared spectrophotometer (UH4150, manufactured by Hitachi High-Tech Science Co., Ltd.).

  By arranging a light source such as a light emitting diode on the light incident end face of the glass plate G for the light guide plate, a so-called edge light type surface light emitting device can be configured. The edge light type surface light emitting device can be used as a backlight of a liquid crystal display or as a surface light emitting illumination device.

  The thickness of the glass plate G for the light guide plate is preferably 0.5 to 10 mm. When the thickness of the glass plate G is 0.5 mm or more, attenuation due to reflection on the glass surface of light propagating during use as a light guide plate is reduced. Further, when the thickness of the glass plate G is 10 mm or less, the number of times the propagating light is scattered by the light scattering portion below the light guide plate increases, and the amount of light extracted outside increases. The thickness of the glass plate G for the light guide plate is more preferably 1.0 mm or more, and further preferably 1.5 mm or more.

  In addition, for example, when the planar light emitting device is provided in an edge light type liquid crystal television, the length of one side of the glass plate is 200 mm or more, but the glass plate G for the light guide plate is not limited thereto. Is not to be done.

  As described above, the influence on the quality caused by irradiating the glass plate G for the light guide plate with ultraviolet rays (wavelength 400 nm or less) is a problem. Here, the degree of the influence on the quality by the irradiation of the ultraviolet rays onto the glass plate G can be confirmed by the above-described ultraviolet-visible-near infrared spectrophotometer.

  The laminated body 12 is packed in a pallet at a glass plate manufacturing factory, and then transported to a display manufacturing factory by a transportation means such as a truck. The laminated body 12 carried into the display manufacturing factory is unpacked at the display manufacturing factory, and the glass plate G is taken out. It is important to protect the glass plate G from ultraviolet irradiation during the period from packing to unpacking.

  The interleaf paper 10 is preferably paper of a size larger than the glass plate G in order to prevent contact between the glass plates G and protect the glass plate G from damage such as scratches and adhesion of dust and the like. Further, since the upper piece 10A of the interleaf paper 10 is adsorbed and held by an adsorbing member for interleaf paper (not shown) when the glass plate G is peeled off from the interleaf paper 10, a predetermined amount (from the upper edge of the glass plate G) For example, it protrudes from 50 to 100 mm. Moreover, it can suppress that the edges of the end surface of the glass plate G contact by the upper piece 10A of the interleaving paper 10. FIG. Similarly, the side piece 10 </ b> B of the slip sheet 10 is also sucked and held by the slip sheet suction member when the glass sheet G is peeled off from the slip sheet 10, so that a predetermined amount (from the side edge of the slip sheet 10 ( For example, it protrudes from 50 to 100 mm.

  Further, the interleaving paper 10 may be bonded to the glass plate G. By bonding the interleaf paper 10 to the glass plate G, the glass plate G can be more effectively protected from damage such as scratches and adhesion of dust and the like. Examples of the method of adhering the interleaf paper 10 to the glass plate G include a method of adhering the interleaf paper 10 to one side of the glass plate G with an adhesive or the like, a method of adhering the interleaf paper 10 to both surfaces of the glass plate G, and the like. Conceivable.

  When the two sheets of interleaf paper 10 cover both surfaces of the glass sheet G, instead of adhering the interleaf sheet 10 to the glass sheet G, the four sides of the two interleaf sheets 10 are adhered, so that the glass sheet G is damaged. It can also be more effectively protected from damages and adhesion of dust (not shown). Further, it is also possible to fold one interleaf paper 10 so as to sandwich the glass plate G, and to bond the facing sides of the folded interleaf paper 10 (not shown).

  The raw material of the interleaf paper 10 is preferably virgin pulp, but may be waste paper. Further, weakly acidic paper or neutral paper can be used as the raw material of the interleaf paper 10.

  The slip sheet 10 preferably has a smoothness of 10 seconds or less as defined in JIS-P8119: 1998. By setting the smoothness of the slip sheet 10 to 10 seconds or less, the cushioning property of the slip sheet 10 can be improved. By sandwiching the interleaving paper 10 having a high cushioning property between the adjacent glass plates G, the edge surface of the glass plate G, in particular, the edge of the end surface for entering the light of the glass plate G is more effectively prevented from damage such as scratches. Can be protected.

  Generally, when the smoothness of the slip sheet 10 is 10 seconds or less, the amount of particles generated from the slip sheet 10 increases. Although it is considered that the particles cause deterioration of the quality of the main surface of the glass plate G, damage such as scratches on the main surface has little influence on the quality of the glass plate G in the glass plate G for the light guide plate. Therefore, it is preferable to protect the edge of the end face of the glass plate G by improving the cushioning property with respect to the interleaving paper 10.

  As an example of the spacer, the slip sheet 10 which is one of the sheets has been described, but examples of other sheets include a resin film and a foamed resin. For example, a resin film or a foamed resin mainly composed of a polypropylene (PP) film, a polyethylene (PE) film, a polystyrene film, or a polyester film can be used. Resin films and foamed resins can also be used in the same form as the above-mentioned interleaf paper 10.

  In order to protect the glass plate G from ultraviolet irradiation, it is preferable to add an ultraviolet absorber to the slip sheet 10 that is a sheet and the resin film.

  After placing the laminated body 12 on the pallet 14, for example, a protective plate 34 is disposed in front of the laminated body 12 (in the direction opposite to the back plate 24), and a part or all of the front surface of the laminated body 12 is disposed. cover. Angle members (not shown) are disposed at both corners of the protection plate 34. Bundling members (not shown) are bound in the horizontal direction, and the pallet 14 and the laminate 12 are fixed. The binding member is composed of, for example, a known polypropylene resin band or other band or string used as a packing material.

  As described above, the light incident end face of the glass plate G for the light guide plate is processed to have low reflection and low scattering compared to other end faces, and the light incident end face can be protected from damage such as scratches. is important. Therefore, it is preferable to pack the laminate 12 on the pallet 14 without the light incident end face of the glass plate G for the light guide plate facing downward. In particular, when there is only one light incident end surface, it is more preferable to pack the laminate 12 on the pallet 14 with the light incident end surface of the light guide plate glass plate G facing upward. “Landing the light incident end face of the glass plate G” means a state in which the light incident end face of the glass plate G is placed on the bottom receiving plate 20 of the pallet 14. It means a state in which the end surface opposite to the light incident end surface of the glass plate G is placed on the bottom receiving plate 20 of the pallet 14. By packing the laminate 12 without the light incident end face of the glass plate G facing downward, the light incident end face of the glass plate G can be prevented from touching a packing container such as the pallet 14, and the light incident end face is damaged such as scratches. Can be avoided.
