Thereby, since the load concentration part does not generate | occur | produce in the glass substrate G, generation | occurrence | production of the streak-like transfer trace which arises when particles, such as paper dust of the interleaf paper 12, are transcribe | transferred to the glass substrate G can be suppressed.

Description

  The present invention relates to a plate-shaped packing pallet, and more particularly, to a flat panel display (FPD) glass substrate such as a liquid crystal display and a plasma display, and a packing pallet for packing a glass plate of an intermediate product in the manufacturing process.

  In recent years, there is an increasing need for large glass substrates used for FPDs and the like. As a packaging pallet for packaging such a large glass substrate, a packaging rack for fixing a glass substrate in a state in which a plurality of glass substrates are arranged upright as disclosed in Patent Document 1 is known.

However, since the packaging rack of Patent Document 1 is transported in a state in which the glass substrate is erected, when it becomes a large glass substrate, the airplane has a low (for example, 2 m or less) storage room or a conventional truck bed (for example, 2). .2m or less) could not be stored due to height restrictions. In addition, when transporting the glass substrate in an upright state, it is necessary to increase the size of one side of the bottom surface (for example, the height of the packaging pallet is 0) in order to secure stability such as preventing the packing pallet from falling. .5 times).
For this reason, the packaging rack of Patent Document 1 has a drawback that the transportation efficiency is poor because the volume and weight of the packaging rack increase as compared with the number of glass substrates to be loaded.

  In order to solve such a problem, the present applicant has proposed a flat packaging box in Patent Document 2. The packaging box of Patent Document 2 is composed of a pedestal and a plate-shaped body storage box placed on the pedestal, and a glass substrate is stacked on a flat bottom plate of the plate-shaped body storage box via interleaving paper. To be stacked. Further, in this packing box, the bottom plate is bent into a V shape (V-shaped angle: 160 ° to less than 180 °), and a glass plate bent into a concave shape by flat stacking is formed along the V-shaped bottom plate. And keep it stable.

Note that the V-shaped bend line of the bottom plate is parallel to the longitudinal direction of the bottom plate. On the other hand, the slip sheet preferably has a rough surface with a smoothness of, for example, 18 seconds or less (JIS P 8119, 1976). The contact area is reduced, and the resin content of the slip sheet is transferred to the glass substrate so that the paper surface has a paper surface. Paper quality that does not cause skin pattern, burns, dirt, etc. is selected. In addition, the resin content of the interleaving paper is 0.05% by mass or less (JIS
P 8205, 1976) is preferable, and the paper quality is selected so that the quality of the glass substrate itself is not adversely affected by the combined effect with the paper surface roughness described above.

In addition, a packaging box is also known in which glass substrates are stacked and stored without interleaving paper.

  However, in the packaging box in which the glass substrates are stacked without interposing the interleaving paper, there is a risk that streak scratches may occur on the surface of the glass substrate. In addition, in the packaging box of Patent Document 2 in which the interleaving paper that does not adversely affect the quality of the glass substrate is interposed as described above, particles such as interleaf paper dust may be transferred in a streak pattern on the surface of the glass substrate. was there.

  The generation of the scratches and the transfer of particles such as paper dust are caused by the concentration of load on a certain location in the glass substrate surface. That is, as shown in FIGS. 12A and 12B, the flat bottom plate 2 of the packaging box 1 on which the glass substrate G is laminated has a pedestal 4 via a plurality of steel materials 3, 3... Having different heights. Is bent in a V shape or curved downward in a convex shape. When a large number of glass substrates G, G... Are stacked on the bottom plate 2 having such a support structure, the glass substrate G, as shown in FIG. The load of G ... concentrates, and the scratches may occur on the surface of the glass substrate G of the load concentration portion 6 or particles 7 such as paper dust of the interleaf paper 5 may be transferred in a streak shape. If the number of glass substrates G stacked on the bottom plate 2 is reduced, the risk of scratches and transfer marks is reduced, but as many glass substrates G, G... As possible can be stored in one packaging box 1. It is not practical to reduce the number of glass substrates G stored in one packing box 1 because it is desired in terms of improving the transportation efficiency.

  The present invention has been made in view of such circumstances, and in particular, even when a large number of plate-like bodies are stacked using interleaving paper, the plate-like bodies are stored without affecting the quality of the plate-like bodies. It is an object of the present invention to provide a packing pallet for a plate-like body.

  In order to achieve the above object, the present invention provides a pedestal and a plate-like body mounting plate which is installed on the pedestal via a support member and a plurality of plate-like bodies are stacked substantially horizontally on the upper surface. And a plate-shaped body mounting pallet having an upper surface curved in a V-shaped cross section, wherein the plate-shaped body mounting plate is constituted by a honeycomb plate. It is a feature.

  In the present invention, it is preferable that the plurality of plate-like bodies are laminated with interleaving paper interposed between the plate-like bodies.

  In the present invention, the preferable packing pallet is provided with a plurality of slip sheet pressing members that press a part of the slip sheet that protrudes from the end face of the plate-like body from the side surface, and the slip sheet pressing surface of the slip sheet pressing member includes: An inclined surface is formed in a direction away from the plate-like body from the upper part toward the lower part.

  In the present invention, the preferred packing pallet includes a plurality of guide members protruding upward from the pedestal corners, and a pallet laminating means comprising a plurality of openings formed on the bottom surface of the pedestal and fitted with the guide members. Is provided.

  According to the packing pallet for a plate-like body according to the present invention, the plate-like body mounting plate is a honeycomb plate having a lightweight, flexible, and highly rigid characteristic, so that the surface of the plate-like body is scratched. Further, since particles such as paper dust of interleaving paper are suppressed from being transferred to the plate-like body, the plate-like body can be stored well without affecting the quality of the plate-like body.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a plate-like packaging pallet according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an external view of a plate-shaped packaging pallet 10 according to the present embodiment, and FIG. 2 is a perspective view illustrating a configuration of a packaging pallet 10 including a plurality of glass substrates (plate-shaped bodies) G, G. FIG.
In this packing pallet 10, a plurality of (for example, 80 to 150) rectangular glass substrates G, G... Are formed in a rectangular shape with a larger area than the glass substrate G between the glass substrates. Stacked and stored via paper 12, 12. The glass substrate G shown in this example is a thin large glass substrate used for FPD. For example, the plate thickness is 0.5 mm to 2.8 mm, and the vertical and horizontal sizes are about 2400 mm × 2100 mm to 3200 mm × 3000 mm. It is a glass substrate. Further, the interleaf paper 12 has a rough surface with a smoothness of 18 seconds or less (JIS P 8119, 1976), for example, and the resin area of the interleaf paper 12 is transferred to the glass substrate G by reducing the contact area. Paper quality that does not cause paper texture, burns, dirt, etc. is selected and used. Further, the resin content of the interleaf paper 12 is 0.05% by mass or less (JIS P 8205, 1976), and the paper quality that does not adversely affect the quality of the plate-like body G itself due to the combined effect with the paper surface roughness described above. Selected and used.

  As shown in FIG. 2, the packing pallet 10 mainly includes a pedestal 14 having a rectangular shape in plan view, a plate-like body placing plate 16, and an interleaf sheet pressing member 18. Since the guide members 20, 20... Constituting the pallet stacking means are erected at the four corners of the packing pallet 10, it is advantageous when the packing pallet 10 is stacked in a plurality of stages in the vertical direction and transported. . This pallet stacking means will be described later.

  As shown in FIG. 3, the pedestal 14 is configured in a frame shape by a plurality of steel materials 22, 22. The steel material 22 is manufactured by, for example, an extruded material made of an aluminum alloy or a material obtained by cutting a steel plate into a predetermined shape, and at least two of these steel materials 22, 22. The frame is constructed by assembling with the steel material 22 so that the lattice planes are substantially parallel. Any metal and resin can be used as long as the material has rigidity and does not generate particles, but aluminum or an aluminum alloy is preferable in terms of weight, rigidity, and cost.

  Further, as shown in FIGS. 1 and 2, forklift openings 28 into which forks of a forklift (not shown) are inserted are formed at two positions on one side surface of the pedestal 14 on all side surfaces of the pedestal 14. As a result, the fork of the forklift can be inserted into the packing pallet 10 from any direction of the vertical and horizontal side surfaces of the pedestal 14, and work can be performed efficiently.

  As shown in FIG. 3, the plate-like body mounting plate 16 is mounted on the pedestal 14 via the vibration absorbing member 30, the inclination angle setting member 32, and the like.

  The vibration absorbing member 30 is composed of a number of shrinkage absorbing materials 34, 34... And extension absorbing materials 36, 36... And is interposed between the pedestal 14 and a tray 38 on which the tilt angle setting member 32 is provided. 14 has a function of absorbing vibration transmitted from the plate-like body mounting plate 16 to the plate-like body mounting plate 16.

  As shown in FIG. 4 (A), the shrinkage absorbing material 34 includes a gel material 40 having elasticity, and a concave bracket 44, a metal plate 42, 42 is provided at the upper end and the lower end of the gel material 40, 44 is fixed by bolts 46 and 46. The lower bracket 44 is fixed to the base 14 with screws 48 and the upper bracket 44 is fixed to the tray 38 with screws 48.

  As shown in FIG. 4B, the stretch absorbent material 36 includes a gel material 50 having elasticity, and a substantially U-shaped bracket 52 is fixed to the upper end of the gel material 50 by a pin 54. The lower end of the bracket 52 is fixed to the pedestal 14 with a bolt 56. A substantially U-shaped bracket 58 is disposed below the gel material 50 with a predetermined gap, and the upper end of the bracket 58 is fixed to the tray 38 by a pin 59.

  As shown in FIG. 3, the contraction absorbent 34 and the stretch absorbent 36 are regularly (eg, alternately) disposed on substantially the entire bottom surface of the tray 38. Thereby, the vibration of the plate-like body mounting plate 16 attached to the pedestal 14 via the receiving tray 38 is absorbed in the vertical direction accompanying the shaking of the pedestal 14 due to vibration during transportation. That is, when the space between the tray 38 and the pedestal 14 is compressed (in the direction of arrow F1 in FIG. 4A), the gel material 40 constituting the shrinkage absorbing material 34 is compressed and contracted, so that the direction of the arrow F1 is reduced. It can absorb vibrations effectively. Further, when the space between the tray 38 and the pedestal 14 is extended (in the direction of arrow F2 in FIG. 4B), the gel material 50 constituting the extended absorbent material 36 is compressed and contracted by the bracket 52 and the bracket 58. Thus, vibration in the direction of arrow F2 can be effectively absorbed. In either case, the gel materials 40 and 50 themselves absorb vibration when compressed. Therefore, it is possible to prevent problems such as positional deviation of the glass substrate G caused by vibrations transmitted from the pedestal 14 to the plate-like body placement plate 16 via the tray 38.

  In addition, it is preferable that the gel materials 40 and 50 are materials that can efficiently absorb, for example, a vibration frequency of 8 to 20 Hz in consideration of a natural frequency generated in a vehicle or an airplane during land transportation or air transportation. For example, a vibration absorbing material such as rubber, resin, or silicone can be used. Further, instead of the gel materials 40 and 50, an elastic body such as compression rubber or a metal compression spring may be used. Furthermore, an elastic body having an elastic action against tension can be used.

  As shown in FIGS. 2 and 3, the tray 38 is configured by assembling a plurality of steel materials 61, 61... Obtained by cutting an extruded material made of, for example, an aluminum alloy or a steel plate into a predetermined shape in a grid pattern vertically and horizontally. And an inclination angle setting member 32 composed of a plurality of steel materials (support members) 60, 60... Fixed on the tray frame 39 and having different heights. That is, the steel materials 60, 60,... Having different heights so that a line segment in a direction parallel to the short side connecting the tops of all the steel materials 60, 60,. Are arranged in a staircase pattern. Each steel material 60 is formed to have a length substantially equal to the length of the long side of the plate-like body mounting plate 16. When the plate-like body placement plate 16 is placed on the tilt angle setting member 32 configured as described above, the plate-like body placement plate 16 is moved by its own weight as shown in FIG. Bending in a V-shaped cross section along the short side of the packing pallet 10. Thereafter, the plate-like body mounting plate 16 is bonded and fixed to the steel materials 60, 60,... With a double-sided adhesive tape or an adhesive, for example, and the V-shaped bent surface is maintained.

In addition, the shape of the plate-shaped body mounting plate 16 is not limited to a V-shaped cross section, and may be formed to be curved downward and convex. That is, the glass substrate G laminated on the plate-like body mounting plate 16 may have a shape corresponding to a shape deformed by its own weight or a shape approximate thereto. Accordingly, in the present invention, the V-shaped cross section includes a downwardly convex curved shape unless otherwise specified. Thereby, since the glass substrate G is laminated in a state of being bent along the plate-like body placement plate 16 by its own weight, the glass substrate G is stably held by the plate-like body placement plate 16 and laterally vibrates. In contrast, the positional deviation between the glass substrates G and G can be suppressed, and a stable packaging state is maintained. The V-shaped angle is preferably 160 ° to less than 180 °, and more preferably 170 ° to 178 °.
The V-shaped bending line D of the plate-like body mounting plate 16 is preferably parallel to the longitudinal direction of the plate-like body mounting plate 16. In the case of a downwardly convex curved plate mounting plate, the convex curved cross section is along the short side (that is, the generatrix formed by the curved surface of the plate mounting plate 16 is the long side. Preferably, they are formed in parallel. As a result, even when the number of the laminated layers is the same, the laminated glass substrate G is compared with the plate-like body mounting plate in which the V-shaped bent line D and the bus formed by the curved surface are formed along the short side. , G... The overall height can be kept low, and the displacement between the glass substrates G and G due to vibration can be further suppressed.

  In addition, the upper surface of the plate-like body mounting plate 16 is covered with a resin sheet 62 in order to buffer vibrations generated during conveyance and the like, and a plurality of glass substrates G, G. It is laminated through. The slip sheet 12 is laminated such that the slip sheet 12 protrudes from each side of the glass substrate G by aligning the approximate center of the slip sheet 12 and the glass substrate G in the planar direction. In this embodiment, the resin sheet 62 uses high-functional urethane foam (Polon: manufactured by Roger Sinoac Co., Ltd.). However, the material is not particularly limited, and has excellent cushioning properties, good workability, and thermal deformation. Any material that is small and does not cause degassing that affects the glass may be used.

  As shown in FIG. 1, for example, two slip sheet pressing members 18 are arranged at predetermined intervals on each of the four sides of the tray 38, and are fixed to the tray 38 with screws 64 and 64. When the slip sheet pressing member 18 is fastened by the screw 64, the glass substrate G is pressed from the side by the slip sheet pressing member 18, and the four sides are sandwiched by the four side slip sheet pressing members 18, 18,. Is done. 6, the slip sheet 12 protruding from each of the four sides of the glass substrate G is pressed by the slip sheet pressing member 18, and the slip sheet 12 is mounted on the plate-shaped body by the slip sheet pressing members 18, 18. Fixed to the mounting plate 16. Thus, the further laminated glass substrates G, G... Are fixed to the plate-like body mounting plate 16 via the interleaf paper 12. In this embodiment, the two slip sheet pressing members 18 and 18 are arranged on each side of the tray 38, but the present invention is not limited to this, and the length of each side is set on each side of the tray 38. Only one corresponding one may be provided, or three or more short slip sheet pressing members may be provided along each side.

  Further, the slip sheet pressing member 18 presses the slip sheet 12 that protrudes from the side surface of the glass substrate G and hangs downward as shown in FIG. 6 in the side surface direction of the glass substrate G. At this time, since the overlapped portion of the end portion of the slipping paper 12 is pressed by the slipping paper pressing member 18, the slipping paper pressing member 18 does not directly contact the side surface of the glass substrate G. While protecting the glass substrate G with flexibility, the laminated body of the glass substrates G can be reliably pressed from the side surfaces of the four sides. Further, even if the glass substrate G tries to move up and down due to vibration, the hanging slip sheet 12 is gripped between the paper pressing member 18 and the side surface of the glass substrate G, and the slip sheet is attached to the plate-like body mounting plate 16. Since the glass substrate G is fixed, the vertical movement of the glass substrate G can be suppressed. In addition, the lateral displacement of the glass substrate G can be prevented.

  By the way, the slip sheet pressing surface 19 of the slip sheet pressing member 18 is formed with an inclined surface in a direction away from the glass substrate G from the upper part toward the lower part according to the thickness of the overlapping slip sheets 12, 12. Thereby, the interleaf sheet 12, 12... Can be surely pressed by the interleaf sheet pressing member 18, and the pressing force applied to the edges of the glass substrates G, G. Therefore, there is no possibility of damaging the glass substrate G by applying an excessive load to the glass substrate G.

  The graph of FIG. 7 shows the relationship of the side paper overlap thickness (mm) to the number of laminated glass substrates G. In the graph of FIG. 7, the number of stacked layers indicates the position of each glass substrate G with the upper surface of the resin sheet 62 in the case where 120 glass substrates G are stacked on the packing pallet 10 being set to 0. The direction indicates the position in terms of the number of glass substrates G in the downward direction from the upper surface of the resin sheet 62. According to the graph of FIG. 7, the overlapping thickness of the interleaf sheets 12, 12... On the side surface of the glass substrate G is about 4 mm from the position of the resin sheet 62 where the number of stacked sheets is 0 to the position of the 70th sheet. From the 71st sheet position to the 120th sheet position, it can be seen that the overlapping thickness of the side slip sheets 12, 12,... Decreases from about 4 mm to 0 mm. That is, when the interleaf pressing surface 19 of the interleaf pressing member 18 is formed vertically, the first to 70th interleaf sheets 12 can be pressed, but the 71st and subsequent interleaf sheets 12 are interleaved. Since a gap is formed between the pressing surface 19 and the interleaf sheet 12, it is difficult to reliably press the interleaving sheet 12. Therefore, the slip sheet pressing member 18 of the present embodiment is an upwardly facing slip sheet pressing surface 19 facing the glass substrate G side so that the 71st and subsequent slip sheets 12 can be securely pressed. Yes. Thus, the slip sheet 12 can be reliably pressed by the slip sheet pressing member 18 and the pressing force from the slip sheet pressing member 18 can be equally applied to all the laminated glass substrates G, G. In this embodiment, the inclination angle of the interleaf sheet pressing surface 19 is preferably 5 ° to 15 °, but is set as appropriate according to the thickness of the interleaf sheet 12 and the number of overlapping sheets 12, that is, the number of stacked glass substrates G. It is what is done.

  Next, features of the packaging pallet 10 configured as described above will be described.

  Since this packing pallet 10 is based on the premise that the glass substrate G is transported in a state where the glass substrates G are horizontally stacked, a sufficient loading efficiency for the transporting means is achieved compared to the conventional vertical transport mode. It can be provided, and even a hangar with a low ceiling, such as an airplane or a truck, can be easily stored as compared with a vertical transfer type.

  Further, the plate-like body placement plate 16 of the packing pallet 10 has a surface on which the glass substrate G is placed curved along a short side of the glass substrate G so as to have a V-shaped cross section or a downward convex shape. Yes. The glass substrate G stacked flat on the plate-like body mounting plate 16 tries to bend into a concave shape by its own weight. At this time, the surface of the plate-like body mounting plate 16 is V-shaped in cross section or convex downward. Therefore, the glass substrate G is laminated in a state where it is bent along the surface of the plate-like body mounting plate 16 by its own weight. As a result, the glass substrate G is stably held on the plate-like body mounting plate 16, and the positional deviation between the glass substrates G and G can be suppressed against vibration, and a stable packaging state is maintained. it can.

  In addition, as shown in FIG. 8, when the packaging pallet 10 is landed by the truck 70, the bent line D (see FIG. 5) of the V-shaped top portion of the plate-like body mounting plate 16 or the generatrix of the convex curved surface is It is preferable to load the packing pallet 10 on the loading platform 72 of the truck 70 so as to be parallel to the traveling direction of the truck 70. Thereby, even if the force at the time of acceleration and deceleration of the track 70 is applied to the laminated glass substrates G, G..., The positional deviation between the glass substrates G, G.

  FIG. 8 shows a transportation form in which the packing pallets 10, 10, 10 stacked in three stages are fixed to the loading platform 72 of the truck 70 by the tacking belts 74, 74.

  As shown in FIG. 9, a locking member in which a plurality of locking holes 78, 78... Are connected to the lower surface edge of the pedestal 14 of the packing pallet 10 to be inserted and locked. 80 is fixed, and a similar locking member 80 is also fixed to the loading platform 72 of the truck 70. The hooks 76, 76 attached to both ends of the belt 74 are locked to the predetermined locking holes 78 of the locking member 80 of the packing pallet 10 and the locking member 80 of the loading platform 72. .., And the stacked packing pallets 10, 10... Are stably fixed to the loading platform 72 of the truck 70. In the present embodiment, the method of hanging the belt is assumed to be staking, but it is not limited to this, and the stacked packing pallets 10, 10... Are stably fixed to the loading platform 72 of the truck 70. It is only necessary to use such a method, and the belts do not have to cross each other.

  FIG. 10 shows (A) an explanatory diagram of the support structure of the plate-like body placing plate 16 of this embodiment and (B) load distribution applied to the plate-like body placing plate 16 when the glass substrate G is loaded on the packing pallet 10. It is explanatory drawing which showed. Since the plate-like body mounting plate 16 is a honeycomb plate as shown in FIG. 5, due to the high rigidity characteristic of the honeycomb plate, the load of the glass substrate G is the supporting point of the steel material 60 as shown in FIGS. Instead of concentrating on P, the entire plate-like body mounting plate 16 is applied uniformly. Thereby, since the load concentration part does not generate | occur | produce in the glass substrate G, generation | occurrence | production of the streak-like transfer trace which arises when particles, such as paper dust of the interleaf paper 12, are transcribe | transferred to the glass substrate G can be suppressed.

  Further, even when a large number of glass substrates G, G,... Are stacked without interposing the interleaving paper 12, no scratches due to load concentration occur on the glass substrate G. Therefore, the glass substrate G can be satisfactorily stored without affecting the quality of the glass substrate G even in the packing pallet in which the glass substrates G are stacked flat.

In addition, it is preferable that the material of the honeycomb plate is made of aluminum because a plate-like body mounting plate 16 having a light weight and high rigidity can be provided. Further, when the honeycomb plate is placed on the upper surface of the inclination angle setting member 32, it is necessary to adjust to the V-shaped upper surface (the honeycomb plate has a self-weight and has a V-shaped cross section). That is, the honeycomb plate has flexibility in the plane direction and has rigidity for receiving the weight of the glass substrate G in the thickness direction. In the present embodiment, in order to prevent foreign matter such as dust and pride from entering from the outside, a material in which plate materials are pasted on the upper and lower sides of the honeycomb plate is applied. The thickness of the honeycomb plate is 4 mm, and the thickness of each of the upper and lower plate members of the honeycomb plate is 0.6 mm. The thicker the thickness is, the higher the rigidity is, but the thinner is preferable for suppressing the bulk of the packaging box. When the thickness of the honeycomb plate exceeds 10 mm, the flexibility in the surface direction is lost, and the inclination angle setting member 32 is not easily adapted to the V shape.
Furthermore, when the thickness is made thinner than 3 mm, for example, when 120 glass substrates G are laminated, the weight of the glass substrate G is superior to the rigidity in the thickness direction of the honeycomb plate, and the load is concentrated on the glass substrate G. There is a risk. For the above reasons, when the honeycomb plate is made of aluminum and 120 glass substrates G are laminated, the thickness of the honeycomb plate is preferably 3 to 10 mm. When the number of glass substrates G is less than 120, the thickness may be appropriately set to 3 mm or less so that the load is not concentrated on the glass substrate G. The material of the honeycomb plate is not limited to aluminum, and may be stainless steel or any other material that has flexibility in the plane direction and rigidity to receive the weight of the glass substrate G in the thickness direction. It may be made of metal such as iron, resin or paper. When applying iron, it is preferable to carry out a rust prevention process. The aluminum honeycomb plate is suitable for the plate-like body mounting plate 16 because it is durable and lightweight. Further, the form of the honeycomb plate can be changed within a range in which substantially the same function as the honeycomb structure can be obtained.

  Therefore, according to the packing pallet 10 of the present embodiment, the glass substrate G can be satisfactorily stored without affecting the quality of the glass substrate G. In addition, it is preferable that the honeycomb plate is made of aluminum because the plate-like body mounting plate 16 having high rigidity and light weight can be provided.

  On the other hand, according to this packing pallet 10, a portion of the interleaf paper 12 covering the upper surfaces of the laminated glass substrates G, G... That protrudes from the side surface of the glass substrate G is disposed around the glass substrate G. The interleaf sheet pressing members 18, 18... Are pressed from the side surface of the glass substrate G, and the interleaf sheet 12 is fixed to the plate-like body mounting plate 16 by the plural interleaf sheet pressing members 18, 18. By sandwiching G, G..., The laminated glass substrates G, G.

  This eliminates the need for an upper lid or cushion material provided with a pressing function for covering the upper surface of the glass substrate G, so that a simple, small, and lightweight packaging pallet 10 can be provided. In addition, when the glass substrate G is packed and when it is unpacked at the carry-in destination, it is possible to omit the work of attaching or removing the upper lid with a pressing function, so that packing and unpacking is easy and efficient. Can do. Further, since the slip sheet pressing surface 19 of the slip sheet pressing member 18 is formed with an inclined surface corresponding to the thickness of the overlapping slip sheets 12, the slip sheet pressing member 18 can securely fix the slip sheet. In addition, the pressing force from the interleaf pressing member 18 can be equally applied to the laminated glass substrates G, G.

  Furthermore, according to this packing pallet 10, as shown in FIG. 11, pallet stacking means for stacking the packing pallets 10 in multiple stages is provided, so that a plurality of packing pallets on which glass substrates G are stacked in a stack are provided. Can be stacked in multiple stages in the height direction. As the pallet stacking means, four guide members 20, 20... Projecting upward from the four corners of the upper surface of the pedestal 14, and tips formed at the four corners of the lower surface of the pedestal 14 and formed on the upper surface of the guide member 20. A means comprising four openings 90, 90... Fitting with the sharpened portion 21 is preferable. The guide member 20 has a sharp tip 21 on the upper surface and a flat tip 20A around the tip. An impact absorbing sheet 92 is attached to the flat tip 20A, and the shock absorbing sheet 92 provides a lower packing pallet. The impact transmitted from 10 to the upper packing pallet 10 is reduced. Furthermore, a rectangular tube-shaped member 94 is fixed around the upper portion of the opening 90, and the prismatic base 21 </ b> A of the sharpened tip 21 fitted in the opening 90 is fitted into the rectangular tube member 94. As a result, stable loadability is ensured. In addition, although the front-end | tip sharp part 21 of a present Example illustrated the square pyramid shape, for example, a cone shape may be sufficient.

  According to this pallet stacking means, in a state where a plurality of packing pallets 10 are stacked, the opening 90 of each packing pallet (excluding the lowermost packing pallet) 10 is a guide for the packing pallet 10 located below the opening pallet 10. Since it fits with the prismatic base 21 </ b> A of the sharpened tip 21 of the member 20, a stable laminated state can be maintained. Further, when stacking the packing pallets 10, the upper packing pallet 10 is positioned at a proper position while being guided by the sharp tip 21 of the guide member 20 of the lower packing pallet 10. Therefore, the pallet stacking means in which the sharp tip 21 of the guide member 20 is formed in a sharp shape also functions as a positioning means for the packing pallets 10 and 10 positioned above and below.

  In addition, this packing pallet 10 can reuse the empty packaging pallet 10 as it is, after packing and conveying the glass substrate G, unpacking, and taking out the glass substrate G. Such reuse can be repeated many times.

As an example of use of the present invention, not only the glass substrate G but also a product that can be stacked flatly on a plate-like body, a plate-like body such as a resin plate or a metal plate can be packed on the packing pallet 10 of the present invention. it can. Considering that a large and thin plate-like body can be stably and efficiently transported safely, it is particularly effective for a glass plate and further a large glass substrate for FPD.
