JP4911276B2 - Plate body packing box, plate body transport method - Google Patents

Description

  The present invention packs a plate-shaped body, particularly a flat panel display (FPD), that is, a large-sized plate-shaped body for a liquid crystal display, a plasma display or the like, or a large-sized plate-shaped body of an intermediate product in the manufacturing process thereof, and then opens again after transporting. The present invention relates to a plate-shaped body packing box formed so as to be packed, and a plate-shaped body transport method, a plate-shaped body loading method, and a plate-shaped body take-out method using the plate-shaped body packing box.

  In recent years, needs for large plate glass used for FPD glass and the like are increasing. As a means for conveying such a large plate glass, for example, a packaging rack in which each plate glass is fixed in a state where a plurality of plate glasses are arranged upright is known (see, for example, Patent Document 1).

However, since this packaging rack is transported in a state where the plate glass is erected, in the case of air transportation, the height dimension is large (for example, 2 m or more), and there are cases where it cannot be smoothly stored in the airplane storage room.

  Further, when transporting the plate glass in an upright state, the dimension of one side of the bottom surface is increased to ensure the stability of the packaging box (for example, 0.5 times the height of the packaging box). However, in a clean room where a display panel manufacturing process is performed, the weight that can be transported by a forklift is limited. For this reason, the number of plate glasses that can be loaded in one packing box is limited. Accordingly, the volume and weight of the packaging box increase with respect to the number of sheet glasses to be loaded, and the conveyance efficiency decreases.

Conventionally, the sheet glass is conveyed in a bare state or covered with a plastic bag or the like. For this reason, the surface of the plate glass has become dirty due to the intrusion of dust or the like, and has also caused scratches. Moreover, when using a plastic bag etc., a plastic bag must be prepared separately and the number of members required for packing increases, and conveyance preparation work and plate glass taking-out work after conveyance become troublesome.
The plate glass has been described above, but the same applies to plate-like bodies such as resin plates and metal plates.

JP 2000-272684 A

  The present invention considers such a current situation, prevents dust from entering the packaging box, can be easily stored in a storage room with a low ceiling by reducing the height dimension during transportation, and It is an object of the present invention to provide a plate-shaped body packaging box that can efficiently and stably transport the plate-shaped body, a plate-shaped body transportation method using the plate-shaped body packaging box, and a plate-shaped body loading / unloading method.

In the state where the packaging boxes are stacked, the opening of each plate-like packaging box (excluding the lowermost packaging box) engages with the guide member of the plate-like packaging box located below, and the packaging box Is supported in a stable state.

FIG. 1 is a longitudinal sectional view of a reference example of a plate-shaped packaging box for explaining a plate-shaped packaging box according to the present invention. In this example, the plate-like body G is applied to a large plate glass. The plate-like body packaging box 1 stores a plurality of (for example, 50) plate-like bodies G in a state of being stacked substantially horizontally. The packaging box 1 includes a pedestal 3, an upper lid 2 installed on the pedestal 3, and a plate-like body accommodation box 14 installed on the pedestal 3 in the upper lid 2.

  The pedestal 3 forms a frame by assembling a plurality of I-shaped frame members 9 formed of an extruded material made of, for example, an aluminum alloy in the form of a grid in the vertical and horizontal directions, and the upper material 4 is fixed to the upper surface of the frame. The underlay material 10 is fixed to the lower surface.

  The plate-like body storage box 14 is placed on the upper material 4 of the pedestal 3 via the vibration absorbing material 17. The storage box 14 is a box having an open top surface, and is constituted by a rectangular bottom plate 15 and four side plates 16a to 16d (FIGS. 5 and 6) provided on four sides thereof. As will be described later, a plurality of plate-like bodies G are stacked in the storage box 14 in a flat position.

  The vibration absorber 17 is preferably a material that can efficiently absorb, for example, a vibration frequency of 8 to 20 Hz in consideration of the frequency generated in the vehicle (or airplane) itself during land transportation or air transportation. For example, a vibration absorbing material such as rubber, resin, or silicone can be used.

The upper lid 2 has an open bottom surface and surrounds the outside of the storage box 14 from above. The upper lid 2 is composed of four side frames 5 and a top plate 6, and has an internal space S for storing a plate-like body therein. Define. The side frame 5 may be an iron plate or the like, or an I-shaped frame material 9 similar to the pedestal 3 may be used. Vibration absorbing means such as a cushion material (airbag or air cylinder) 20 is disposed on the lower surface side of the top plate 6 to elastically fix and hold the plate body G loaded in the plate body storage box 14.

  In addition, if the cushion material 20 exists between the top plate 6 and the plate-like body G, and can press and hold the plate-like body G elastically from the top, it will be outside the side plates 16a-16d of the plate-like-body storage box 14. It may stick out.

FIG. 2 is a top view of the plate-like package box 1. The plate-like packaging box 1 is preferably rectangular in plan view in accordance with the shape of the plate-like body G to be stored. When loading a plate-like body into the internal space S and when taking out the plate-like body from the internal space S, the upper lid 2 is removed from the base 3 by appropriate means such as human power or a robot.

When the plate-like body packaging box 1 is transported to a destination by, for example, a truck, an airplane, or the like (hereinafter referred to as transport means), it is stored in a loading platform or a storage chamber of the transport means in a stacked state over a plurality of stages. Therefore, it is assumed that another plate-shaped packaging box is stacked on the top plate 6 of the upper lid 2, and an impact absorbing pad (buffer material) 7 for protecting the plate-shaped body is provided around the upper surface. Are pasted. The shock absorbing pad 7 is made of an elastic material such as rubber.

At each corner of the top plate 6, the top plate 6 has a square frustum-shaped guide member 8 projecting upward from the shock absorbing pad 7 in order to align with the upper plate-shaped body packaging box to be placed. Fixed on top. The shape of the guide member 8 is not limited to a square frustum shape, and may be a truncated cone shape, for example. The part of the plate-like packaging box that engages with the guide member 8 will be described later.

FIG. 3 is a bottom view of the plate-like body packaging box 1. In order to stably support the plate-shaped object storage box 14, the I-shaped frame material 9 is assembled in a lattice shape by a plurality of vertical and horizontal pieces. Intersections between the I-shaped frame members 9 are integrated by means such as welding.

As shown in FIG. 1, the pedestal 3 is configured by a lattice frame made of an I-shaped frame material 9. A rectangular opening (guide hole) 11 for receiving the guide member 8 of the packing box 1 stacked on the lower side is formed at each corner of the underlay material 10 fixed to the lower surface of the pedestal. An impact absorbing device (shock absorber) 12 can be attached to the lower surface of the upper covering material 4 above the opening 11 in order to reduce the impact with the guide member 8. The impact absorbing device 12 is composed of, for example, an air cylinder, a rubber damper, and the like. When the packaging boxes are stacked, the lower portion of the impact absorbing device 12 is stacked on the lower side entering from below through the opening 11. It is provided at a position where it abuts against the guide member 8 of another plate-like packaging box 1.

The upper material 4 is made of, for example, an iron plate, and is necessary for stably placing the storage box 14 on the pedestal 3 and for preventing dust from entering the internal space S (FIG. 1) for storing the plate-like body. It is. Similarly, the underlay material 10 is made of, for example, an iron plate, and is necessary for smoothly transporting the packaging box 1 by a conveyor when the packaging box 1 is conveyed by a roller conveyor or the like. However, if the conveyance by a conveyor or the like can be performed without any problem, the underlaying material 10 can be omitted.

For example, two forklift holes 13 for receiving a fork of a forklift (not shown) are attached to one I-shaped frame material 9 in the vertical and horizontal I-shaped frame material 9. As a result, the fork of the forklift can be received in the plate-like body packaging box 1 from both the vertical and horizontal directions of the rectangular pedestal.

FIG. 4 is a perspective view showing a state before the guide member 8, the opening 11, and the impact absorbing device 12 are engaged when a plurality of the plate-like packaging boxes 1 are stacked. When another plate-shaped packaging box 1 is placed on the plate-shaped packaging box 1, the upper plate-shaped packaging box 1 is placed in the lower plate-shaped body in the opening 11 formed in the underlaying material 10. The guide member 8 of the packing box 1 is positioned so as to enter, and is gradually lowered toward the lower plate-shaped packing box 1. At this time, the guide member 8 of the lower plate-shaped packaging box 1 enters the opening 11 of the upper plate-shaped packaging box 1. As described above, the guide member 8 is formed in the shape of a square frustum, and the opening 11 for receiving the guide member 8 is also rectangular. Therefore, even if the guide member 8 and the opening 11 are not accurately positioned. In the approaching process, the side wall of the guide member 8 and the opening 11 interfere with each other, so that the horizontal displacement between the upper plate-like packaging box 1 and the lower plate-like packaging box 1 is automatically corrected. Thus, accurate alignment between the packaging boxes at the time of stacking is achieved (positioning means).
The upper end surface of the guide member 8 comes into contact with the lower end surface of the vibration absorbing device 12 of the upper packaging box 1 and a vibration absorbing action in the vertical direction is obtained in a stacked state.

FIG. 5 is an external perspective view of the plate-like body storage box 14, and FIG. 6 is a cross-sectional view seen from the direction of arrow V in FIG. 5.
The plate-like body storage box 14 is composed of a bottom plate 15 and four side plates 16a to 16d around it. The plate-like body G is stored in a stacked state in a box body having an open top composed of the bottom plate 15 and the four side plates 16a to 16d. In order to protect the plate-like body G against an impact from the outside of the packaging box, a plurality of vibration absorbing materials 17 are arranged between the bottom plate 15 and the upper material 4 of the base 3 (FIG. 1).

As shown in FIG. 1 and FIG. 6, the bottom plate 15 of the plate-like object storage box 14 has the whole bottom plate with respect to the upper material 4 with one apex (corner) P as the lowest point among the four corners. For example, it is arranged on the upper material 4 so as to be inclined at a predetermined angle α in a range of 0 to 5 degrees (preferably about 2 degrees). For this reason, in this embodiment, each vibration absorbing member 17 is interposed between the bottom plate 15 and the upper covering member 4 so as to have different thicknesses as shown in FIG. As will be described later, the bottom plate 15 may be inclined by 0 degree (that is, not inclined) as long as the bottom plate 15 has a concave shape so that lateral displacement of the plate-like body can be suppressed.

Thus, by tilting the bottom plate 15 with respect to the upper material 4 at a predetermined angle α, the two side plates 16a, 16b in which each plate-like body G forms the apex P in the plate-like body loading state. Therefore, the plate-like body G is stably held against the vibration in the lateral direction, and the positional deviation between the plate-like bodies is also corrected.

In this connection, as shown in FIG. 5, of the four side plates 16 a to 16 d that surround the four sides of the bottom plate 15, the two side plates 16 a and 16 b constituting the apex P as the lowest point are used as they are. The side plates 16c and 16d located on both sides of the vertex Po diagonally opposite to the vertex P are fixed to the bottom plate 15 or other members (for example, shown in the figure) so as to be slidable on the bottom plate 15. It is attached to the rod tip of an air cylinder that does not. That is, the side plates 16a and 16b are fixed side plates, and the side plates 16c and 16d are movable side plates.

Thus, for example, when the plate-like body G is placed on the bottom plate 15 or when the plate-like body G is taken out from the bottom plate 15, the side plates 16c and 16d are temporarily moved from the opposing side plates 16b and 16a. By separating them, the plate-like body receiving area on the bottom plate 15 can be enlarged, and the glass loading operation and the glass removing operation can be facilitated. In the state where the loading of the plate-like bodies is completed, the movable side plates 16c and 16d are arranged on the side surfaces of the plate-like body G so that the individual plate-like bodies G do not move in the plate-like body storage box 14 during the transportation. It is held in the butted state.

When the bottom plate 15 is inclined, in the above example, one vertex P is set as the lowest point. However, for example, two points P and P ₁ may be set as the lowest point. However, in consideration of easily aligning the positions of the plate-like bodies G, one vertex is preferable at the lowest point position.

FIG. 7 shows another reference example .
In this embodiment, a cushion member 25 is disposed between the plate-like body 14 housed in the plate-like body housing box 14 and the side plates 16a, 16c, 16d. In this case, for example, when the bottom plate 15 is inclined with the apex P as the lowest point as shown in FIG. 5 described above, the plate-like body G is abutted against the side plate 16b and placed on the remaining three sides. A material 25 is disposed.

Alternatively, as described above, the vertex P, (as the side plates of the lowermost position ie the side plate 16b) to two points as the lowest point of the P _1, abutted against a plate-like body G is placed on the side plate 16b, then The cushion material 25 is disposed on the remaining side plates 16a, 16c and 16d.

FIG. 8 shows still another reference example .
In this embodiment, the side frames 5 on the four sides of the upper lid 2 are fixed on the pedestal 3 so that the top plate 6 can be separated from the side frames 5, and only the top plate 6 is removed from the pedestal 3 when packing or unpacking. The upper surface of the base 3 is opened, and the plate-like body G is loaded or taken out. In this case, only the side plate 16b is provided among the side plates 16a to 16d of the plate-like body storage box 14, and the other three side plates 16a, 16c and 16d are omitted. The bottom plate 15 is inclined with the two apexes P and P1 (FIG. 5) described above as the lowest point. Here, the plate body G is abutted against the side plate 16b at the lowest position and positioned on the bottom plate 15, and the cushion material 25 is placed between the remaining three sides and the side frame 5 fixed to the pedestal 3. It arrange | positions and the plate-shaped body G is fixedly held elastically. Such a configuration simplifies the configuration of the plate-like body storage box 14.

9 (A) and 9 (B) are explanatory views of the shape of the plate-shaped object storage box in which the bottom plate is recessed. The bottom plate 15 takes into account the deflection (due to its own weight) of the entire plate-like body to be placed, for example, with a curvature of a radius of 10 m to 25 m, in the short side direction of the plate glass, in the long side direction, or in the short side and long side. It may be formed in a slightly concave shape in the side direction. As a result, the plate-like body G loaded on the bottom plate 15 can be prevented from being displaced due to lateral vibration, and can be stably held. The direction of curve formation is particularly preferably the short side direction.

The size of the plate-like body G to be stored is, for example, a large plate-like body having a plate thickness of 0.5 mm to 1.3 mm and a length and width of about 1400 mm × 1700 mm to 2400 mm × 2800 mm. In addition, when stacking in the plate-like body storage box 14, in order to avoid that the plate-like bodies G are in direct contact with each other, they are stacked with a thin interleaf paper 18 sandwiched between the plate-like bodies. Is preferred. The interleaf paper 18 has a rough surface with a smoothness of 18 seconds or less (JIS P 8119, 1976), the contact area is reduced, the resin content in the interleaf paper 18 is transferred to the plate-like body G, and the paper surface is made of paper. Paper quality that does not cause skin patterns, burns, dirt, etc. is preferred. Further, the resin content of the interleaf paper 18 is 0.05% or less (JIS P 8205, 1976), and the paper quality is such that the quality of the plate-like body G itself is not adversely affected by the combined effect with the paper surface roughness described above. .

Thus, the plate-like body G laminated on the bottom plate 15 is elastically provided by a cushioning material 20 such as an airbag provided on the lower surface side of the top plate so as not to vibrate up and down on the bottom plate 15 during the conveyance process. Press the plate-like body G. As a result, the plate-like body storage box 14 including the plate-like body G is supported in a floating state by the cushioning material 20 from the top and the vibration absorbing material 17 from the bottom, and an impact is imposed from the outside when the packaging box is transported. Even if the packaging box itself vibrates up and down with conveyance, the plate-like body G is held in a stable state.

As described above, the plate-like packaging box 1 according to the present embodiment can stably store a plurality of large plate-like bodies G in a flat stacked state. Moreover, the conveyance is performed in the state which piled up the same packing box 1 in many steps up and down with the plate-shaped body G with flat stacking. Thus, by transporting the large plate-like bodies in a flat state, they can be easily and efficiently accommodated in a storage room or the like having a low ceiling height, and a large number of plate-like bodies can be stably transported by various transportation means.

When the plate-like body G is loaded on the plate-like body packaging box 1 or when the plate-like body G is taken out from the plate-like body packaging box 1 after being transported, the storage box 14 of the plate-like body packaging box 1 is placed in a horizontal plane. The packaging box 1 can be raised to form a predetermined angle of 0 to 90 degrees, preferably 75 to 85 degrees.

FIG. 10 is an external perspective view of a tilting table for placing the packing box 1 and raising it at a predetermined angle, and FIGS. 11A and 11B are diagrams showing the usage state of the tilting table.
The raising / lowering base 21 is an L-shaped member that includes a large table portion 22 and a small table portion 23 that stands upright from one end of the large table portion 22. The raising / lowering base 21 is provided at a position where a predetermined plate-like body G is loaded and unloaded on a conveyance path of a chain conveyor formed of the chain C. The large table portion 22 and the small table portion 23 are formed with two parallel grooves 24 for passing the chain C of the conveyor along the transporting direction of the packing box.

When being transported by the chain conveyor, when the packing box 1 reaches the raising / lowering base 21 with the large table portion 22 in a horizontal state, the packing box 1 abuts against the small table portion 23 as shown in FIG. Thereafter, as shown in FIG. 11B, the raising / lowering base 21 is raised (arrow D). This standing angle can be appropriately adjusted between horizontal and almost right angles. This standing angle is adjusted to an optimum angle at which the robots for loading and unloading the plate-like body smoothly operate.

By using such a raising / lowering table, the plate-shaped body G is loaded from the plate-shaped body packaging box 1 in the horizontal state as it is by loading and unloading the plate-shaped body with the packaging box 1 raised from the horizontal. Compared to the case where the plate-like body G is taken out or newly stacked on the plate-like body G in the plate-like body storage box 14, the plate-like body G itself is easy to handle, and the plate can be obtained by a robot or human power. The plate-like body G can be easily extracted from the inside of the plate-like body storage box 14, or the plate-like body G can be easily loaded on the plate-like body storage box 14. In addition, the loading / unloading method of the plate-like body that loads or takes out the plate-like body in the state where the packaging box is raised in this manner reduces the load on the plate-like body G and reduces the possibility of glass damage.

As described above, the plate-shaped body packaging box according to the present invention has a plate-shaped body storage box on which a plurality of large plate-shaped bodies can be mounted in a flat stack, and a frequency within a predetermined range under the plate-shaped body storage box. By including the vibration absorbing material that absorbs vibration, a plurality of large plate-like bodies can be conveyed in a stable state in which vibration from the outside is not easily transmitted to the plate-like body. In addition, since this plate-like body packaging box is premised on being transported in a state of being flattened substantially horizontally, it has sufficient loading efficiency for transport vehicles compared to the conventional vertical transport mode. It can be provided and can be carried into a storage room with a narrow height direction such as an aircraft without any trouble.

  The plate-like body packaging box of the present invention can be used again as it is after the plate-like body is packed and conveyed, unpacked after conveyance and taken out of the plate-like body. Such reuse can be repeated many times.

FIG. 12 shows a plate- like package box according to another reference example, and FIG. 13 is a top view thereof.
As shown in the figure, the plate-like body packaging box 1 includes a pedestal 3 and a plate-like body storage box 14. The pedestal 3 forms a frame by assembling a plurality of I-shaped frame members 9 formed of an extruded material made of, for example, an aluminum alloy in the form of a grid in the vertical and horizontal directions, and the upper material 4 is fixed to the upper surface of the frame. The underlay material 10 is fixed to the lower surface. The pedestal 3 may be formed by assembling a member such as a square pipe as a frame material in addition to the I-shaped frame material 9.

  At four corners of the pedestal 3, pillar members 31 (stacked members in the claims) are provided protruding upward. The shock absorbing pad 7 is affixed to the upper surface of the column member 31, and the guide member 8 is attached thereon. By inserting and fitting the guide member 8 into the opening 11 provided on the lower surface of the column member 31, a plurality of plate-shaped packaging boxes 1 can be stacked (see FIG. 19). Note that the column member 31 may be fixed to the base 3 using an angle material (not shown) or the like. Further, the column member 31 is not limited to the columnar shape, and may be a wall-shaped member formed on the base 3 along one side.

  The plate-like body storage box 14 is placed on the upper material 4 of the pedestal 3 via the vibration absorbing materials 32 and 33. The vibration absorbing material is composed of the shrinkage absorbing material 32 and the extension absorbing material 33, whereby the vertical vibration with respect to the plate-like body G being conveyed can be mitigated. The plate-like body G is placed on the bottom plate 15 of the plate-like body storage box 14. The side wall of the plate-like container 14 is composed of a fixed side plate 34, a movable side plate 35, and a presser roll 36, and the interleaf paper 18 interposed between the plate-like bodies G is sandwiched between the presser roll 36 and the bottom plate 15. The plate-shaped body storage box 14 is covered with a cover 42 after the plate-shaped body G is stored. Thereby, adhesion of dust to the plate-like body G can be prevented. In FIG. 13, the cover 42 is omitted.

  As shown in FIG. 13, the side plates 34 and 35 are provided on opposite long sides of the rectangular bottom plate 15 of the plate-like object storage box 14. Two presser rolls 36 are provided on each of the opposing short sides. As shown in FIG. 12, the bottom plate 15 is bent in a V shape, and a bending line D (FIGS. 13 and 15) at the V-shaped top is parallel to the long side of the bottom plate 15.

  The pillar members 31 at the four corners of the pedestal 3 are provided with triangular or rectangular reinforcing walls 31a along the sides of the pedestal (the example in the figure is a triangle).

FIG. 14 shows another example of the plate-like body packaging box.
In this example, column members 31 are provided on the upper surface of the upper material 4 of the base 3, and openings 11 are formed at the four corners of the lower material 10. Other configurations are the same as the example of FIG.

FIG. 15 is a schematic view of the plate-shaped body storage box, and FIG. 16 is a cross-sectional view of the vicinity of the presser roll in a state where the plate-shaped body is stored.
As described above, the plate-like body storage box 14 includes the bottom plate 15, the fixed side plate 34, the movable side plate 35, and the presser roll 36. The movable side plate 35 is rotatable with respect to the bottom plate 15 in the direction of arrow R with the side plate lower side as an axis. The presser roll 36 is movable in the vertical direction with respect to the bottom plate 15. When the plate-like body G is accommodated in the plate-like body packaging box 14, one side of the plate-like body G is abutted against the fixed side plate 34 in a state where the movable side plate 35 is tilted and placed on the bottom plate 15. Next, the interleaf paper 18 is placed on the plate-like body G, and the plate-like body G is placed thereon again. When a predetermined number of plate-like bodies G are stacked, the movable side plate 35 is raised. Next, the presser roll 36 is lowered (arrow F), and the slip sheet 18 protruding from the plate-like body G is sandwiched between the presser roll 36 and the bottom plate 15. Thereby, the plate-like body G is fixed by the presser roll 36 via the interleaf paper 18. Thereby, even if the plate-like body G tries to move up and down by vibration, it can be suppressed by the presser roll 36. Further, it is possible to prevent the plate-like body G from being displaced in the lateral direction. The presser roll 36 may have any shape as long as it can suppress the slip sheet, such as a columnar shape.

  If a presser roll having a diameter larger than the height of the stacked plate-like bodies G is used, the lateral displacement of the plate-like bodies G can be reliably suppressed.

  Instead of the rotary side plate 35, it may be slidable in the direction of arrow B as shown in FIG. By providing such a movable side plate 35, the opening surface on the bottom plate 15 is widened, so that the work for inserting and removing the plate-like body G is facilitated. When the side plate 35 is returned to the original state after the plate-like body G is mounted, the plate-like body G is formed in a size and shape so as to press the plate-like body G toward the fixed side plate 34 through the slip sheet protruding from the plate-like body G. It is preferable. Therefore, it is preferable that the size of the slip sheet is such that it protrudes from the plate-like body G in the three side directions on both the short side and the long side on which the movable side plate 35 is provided.

  The bottom plate 15 is bent in a V shape, and the bending line D is parallel to the longitudinal direction of the bottom plate 15. Instead of the bottom plate bent in a V shape, a curved arcuate bottom plate convex downward may be used. Also in this case, the curved surface is preferably formed along the short side (that is, the generatrix of the curved surface is parallel to the long side). Thus, by making the bottom plate 15 into a concave shape, the plate-like body G can be stably placed, and the plate-like body G can be prevented from being obliquely displaced in the axial direction during conveyance. The V-shaped angle is preferably 160 ° to 180 °, and more preferably 170 ° to 176 °. The bottom plate 15 is preferably placed so as to be horizontal with respect to the pedestal 3, but may be inclined so that one side is lowered as described above (FIG. 6).

FIG. 17 shows an example of a vibration absorbing material, where (A) is a shrinkage absorbing material and (B) is a cross-sectional view of an elongation absorbing material.
The shrinkage absorbing material 32 is configured by attaching a gel material 38 having elasticity via a metal plate 39 to a bent bracket 37 fixed to the bottom plate 15 and the upper covering material 4 by screws 43. The gel material 38 and the metal plate 39 are fixed by an adhesive or the like, and the bracket 37 is fixed by a bolt 40 fixed to the metal plate 39 or integrally formed.

  The stretch absorbent member 33 is configured by attaching an elastic gel member 38 via a metal plate 39 between two brackets 41 having a substantially U-shaped cross section fixed to the bottom plate 15 and the upper covering member 4 by screws 43. The The gel material 38 and the metal plate 39 are fixed by an adhesive or the like, and the bracket 37 is fixed by a bolt 40 fixed to the metal plate 39 or integrally formed.

The contraction absorbent 32 and the stretch absorbent 33 are regularly arranged on the substantially entire lower surface of the bottom plate 15. Thereby, the up-and-down vibration of the plate-shaped object storage box 14 accompanying the shaking of the base 3 by the vibration in conveyance can be suppressed. That is, in the case of (A), when the space between the bottom plate 15 and the upper covering material 4 is compressed (arrow F ₁ ), the gel material 38 is compressed to provide an effective cushioning action. In the case of (B), when the space between the bottom plate 15 and the upper covering material 4 is extended (arrow F ₂ ), the gel material 38 is compressed and an effective cushioning action is obtained. In either case, the gel material 38 itself provides a cushioning action when compressed. Instead of the gel material 38, an elastic material such as compression rubber or a compression spring material such as metal may be used. An elastic body having an elastic action against tension can also be used.
