Description

  The present invention relates to a flat plate display, particularly a large glass plate for a liquid crystal display, a plasma display (PDP), etc., and a glass plate packing box for packing and transporting a large glass plate of an intermediate product in the manufacturing process, a packing method and unpacking Regarding the method.

  In recent years, there has been an increasing need to increase the size of glass plates used for glass for liquid crystal displays, etc., but conventionally, as a means for conveying large glass plates for general use, the glass plates are placed side by side and then fixed. A packaging rack is used (see, for example, Patent Document 1). However, since this packaging rack is transported in a state where the glass plate is exposed or covered with a plastic bag or the like, the glass surface becomes dirty or causes scratches due to intrusion of dust or the like. Moreover, the number of members increases with the use of a plastic bag or the like.

  On the other hand, Patent Document 2 describes a glass plate packaging box that uses a box-shaped packaging box to store and transport a glass plate for a liquid crystal display. However, since this packing box has a groove for sliding and storing the glass plate on the inner wall, the operator must store the glass plate from above along this, and the workability is poor. It is. Also, when the storage of the glass plate is automated, equipment with a large movable range in the vertical direction is required as the glass plate becomes larger, resulting in an increase in equipment size and cost. Further, since the number of glass plates stacked is small and the number of sheets that can be stored and transported at a time is limited, the transport efficiency is poor. In addition, this packing box is prepared on the premise that a glass plate having a size of 600 × 500 to 1300 × 1100 (mm) or the like is packed, and workability is required for packing a glass plate of a larger size. There are difficulties in terms of strength and transport costs.

Hereinafter, the packaging of the glass plate using the glass plate packaging box according to the present invention will be described in order.
FIG. 6 is a view showing a state before placing the glass plate, (A) is a front view, (B) is a side view, and (C) is a top view. 7A is a front view, and FIG. 7B is a side view when the bottom receiving plate and the back receiving plate are attached to the bottom piece and the vertical piece of FIG.
As illustrated, a bottom piece 12 and a vertical piece 13 are provided on the bottom plate 3. The upper portion of the vertical piece 13 is provided with the plate material 27 described above, and is fixed by the rear plate 6 and screws 28. A bottom receiving plate 14 is placed on the bottom piece 12, and a back receiving plate 15 is leaned on the vertical piece 13 to constitute the base 2. The upper surface of the bottom piece 12 is an inclined surface on which the rear plate 6 side is lowered, and the inclination angle is preferably 5 to 25 °, more preferably 10 to 20 °, and particularly preferably about 18 °. The vertical piece 13 is inclined obliquely rearward so as to be approximately 90 ° with the upper surface of the bottom piece 3 in accordance with the inclination angle. Note that the top surface inclination angle of the bottom piece 12 may be adjustable.

  Cushioning materials 29a and 29b are attached to the bottom receiving plate 14 and the back receiving plate 15, respectively, to prevent damage due to contact with the glass plate when the glass plate is placed. As this cushioning material, it is a material with a high elastic modulus, a high elastic recovery rate, and it is difficult for dust to come out by friction with the end face of the glass plate, and a polyethylene (PE) type cushioning material which is a material with little degassing, An elastomer or the like is preferable. Affixing a predetermined cushion material 29a to the entire surface of the base plate 14 shifts the natural frequency of the pedestal from the frequency of conveyance by a truck, etc., and can reduce resonance, thus preventing vibration of the glass plate during conveyance. And can be transported safely and efficiently. Further, if the cushion material 29b is attached to the entire surface of the back support plate 15, the entire surface of the glass plate is received by the cushion material 29b when the glass plate is pressed against the back support plate 15 during conveyance. It can be transported safely. At this time, if the width of the bottom receiving plate 14 is made smaller than the width of the glass plate to be placed, it is possible to prevent the cushion material 29a from being worn or damaged due to contact with the corners of the glass plate. Further, the bottom receiving plate 14 and the back receiving plate 15 may be provided with ribs (not shown) in order to ensure strength as necessary.

FIG. 8 is a view showing a state in which a glass plate is placed on a pedestal, where (A) is a front view and (B) is a side view.
The glass plate 18 is stood and placed side by side from the back plate 15 side. At this time, since the glass plate 18 is stood along the inclination of the back support plate 15, the operator can easily, efficiently and safely perform the work of placing the glass plate. Since each glass plate 18 is in contact with the glass plate 18 on the back support plate 15 side by its own weight, there is no useless gap between the glass plates 18. Moreover, since stabilization of the glass plate in conveyance can be aimed at, the shift | offset | difference and collapse of the glass plate 18 can be prevented, and the damage | wound and crack of the glass plate 18 can be prevented.

  Between each glass plate 18, in order to prevent the glass plates 18 from interfering with each other during transportation and to be damaged, and to place a large number of glass plates, a slip sheet 30 is sandwiched. The slip sheet 30 is a sheet sandwiched between the glass plates 18 to avoid direct contact between the glass plates. For example, a sheet is sandwiched between glass plates by placing a sheet (such as a slip sheet or a resin sheet that adheres to the glass) on the top surface of a glass plate that is placed flat in a clean room. The glass plate and the sheet portion protruding from the glass plate are adsorbed by a robot or the like, and the sheet and the glass plate are placed on the pedestal. Thereby, it can prevent that dust etc. mix between a glass plate and a sheet | seat. The slip sheet 30 is a large glass for a liquid crystal display. In order to prevent the resin component in the slip sheet from being transferred to the surface of the glass plate 18 and causing a paper texture, scorch or dirt, the smoothness of the paper In JIS P 8119 (1976) for a rough surface of 20 seconds or less, preferably 18 seconds or less, more preferably 10 seconds or less, thereby reducing the contact area with the surface of the glass plate 18 and transferring the resin content. By preventing the resin content of the paper from 1.0%, preferably 0.06%, more preferably 0.05% and even more preferably 0.04% or less in JIS P 8205 (1976), the rough surface What maintains the quality of the glass plate 18 by the combined action is used. As a result, even when particles or the like (pulp or fine resin scraps) are generated due to the slip sheet, the particles adhere to the surface of the glass plate in combination with placing the glass plate upright on the base. And can be easily removed by subsequent cleaning of the glass plate. In addition to the interleaving paper, a resin sheet such as polypropylene (PP) or polyethylene (PE) can be used. In this case, the thickness is preferably 1 to 2 (mm), and the inside is preferably hollowed so as to receive the periphery of the glass plate. Moreover, the some strip-shaped sheet | seat which receives only the important point of a glass plate may be sufficient. Further, it may be a thin film-like resin sheet covering the front surface of the glass plate. In consideration of placing many glass plates and removing the sheet easily, slip sheets are particularly preferable.

  The interleaving paper 30 protrudes above the upper side of the glass plate 18 and is sandwiched between the glass plates 18. Thereby, a glass plate can be peeled from a slip sheet only by providing the apparatus for pressing a slip sheet upward. The interleaving paper 30 may be sandwiched so as to protrude from both sides of the glass plate 18. The slip sheet 30 is preferably larger than the surface area of the glass plate 18, and the protrusion length is preferably 30 to 100 (mm), and more preferably about 50 (mm) in consideration of the deflection of the slip sheet. Thus, by interposing the interleaf 30 so as to protrude upward, when the glass plate 18 is taken out from the pedestal 2, the glass plate 18 can be taken out while pressing the interleaf 30, and is compressed and closely adhered during conveyance. The glass plate 18 and the slip sheet 30 can be easily taken out. At this time, static electricity generated between the interleaf 30 and the glass plate 18 is neutralized by blowing static elimination air between the interleaf 30 and the glass plate 18 from above (not shown). The slip sheet 30 and the glass plate 18 can be easily separated, and workability is improved.

  Since the base 2 and the bottom plate 3 are formed by welding or screwing an iron material, a large glass for a liquid crystal display exceeding 1300 × 1100 (mm), for example, 1850 × 1500 (mm), 2200 × 1870 (mm) ), 2400 × 2200 (mm), and a plurality of glass sheets having a thickness of 0.5 to 0.7 (mm), etc., it is possible to cope with the weight in strength. Since all the weight of the glass plate 18 is received by the base 2 and the bottom plate 3, the rear plate 6 is made of a resin plate member (for example, plastic corrugated cardboard made of polypropylene) having a hollow portion with an aluminum frame as described above (FIG. 4). A relatively lightweight material such as a reinforced one is used.

FIG. 9 is a view showing a state in which glass plates are bound together, (A) is a front view, and (B) is a side view.
After placing a plurality of glass plates 18 on the pedestal 2, the front side of the glass plate housing 19 made of the plurality of glass plates 18 is covered with a protective plate 21 made of resin or the like, and angle members 22 are arranged at both corners. These are bound together with a band 20 (two in the figure). The band 20 securely binds the glass plate storage body 19 together with the vertical piece 13 by engaging a fixing bracket (not shown) provided at the end of the belt member whose length can be adjusted with a toggle clamp (not shown). . Thus, by binding the glass plate storage body 19 using the band 20, the whole can be firmly fixed with a simple mechanism. Further, if the protective plate 21 is a member having cushioning properties (elasticity), the toggle clamp can be bound more firmly after the glass plate 18 is bound by the band 20.

FIG. 10 is a view showing a state in which the side plate is attached, in which (A) is a front view and (B) is a side view.
After binding the glass plate storage body 19, the side plate 7 is fitted into the U-shaped member 8 provided on the bottom plate 3. At this time, the side plate 7 is fitted into an aluminum material 44 (FIG. 4) having a U-shaped cross section of the rear plate 6 and fixed by a screw 10 such as a thumbscrew. As described above, by using the U-shaped member 8 and the aluminum material 44 to fit the side plate 7, the packaging box 1 can be formed easily and reliably, and workability is improved.

FIG. 11 is a schematic view showing an engaging portion between the side plate and the bottom plate.
A columnar protrusion 11 having an engagement member 17 at the tip is formed on the lower surface of the bottom plate 7. On the bottom surface of the U-shaped member 8, an engagement hole 23 is formed in which a wide hole 23a and a narrow hole 23b are continuously formed. When the side plate 7 is fitted into the U-shaped member 8 of the bottom plate 3, the columnar protrusion 11 is inserted into the wide hole 23 a of the engagement hole 23, and then slid in the direction of the arrow S to make the columnar protrusion 11 narrow. The engaging member 17 is engaged with the narrow hole 23b, and the side plate 7 is fixed to the bottom plate 3.

  The engaging member 17 may be an L-shaped hook member. In this case, the engagement hole 23 is simply a long hole, and the side plate 7 and the bottom plate 3 are locked to each other by inserting and sliding the hook.

  FIG. 12 is a view showing a state where the front plate is attached, (A) is a front view, (B) is a side view, and FIG. 13 is a schematic view showing a fitting portion between the front plate and the side plate.

  The front plate 5 is fitted into a U-shaped member 8 provided on the side edge of the bottom plate 3. At this time, the side plate 7 is fitted into an aluminum material 9 having a U-shaped cross section, and is fixed to the side plate 7 with screws 10 provided on the upper portion of the front plate 5. At the time of this fitting, the projections 24 formed on the aluminum material 37 of the front plate 5 are engaged with the cut holes 25 formed on the upper surface of the side plate 7, so that the joining between them is ensured and made stronger. be able to.

  If the mounting positions of the screws 10 on the front plate 5 and the rear plate 6 are the same and the left and right surfaces of the side plate 7 have the same specifications, the side plate 7 can be mounted even if the left and right sides are interchanged.
