Description

  The present invention relates to a glass plate package, and more specifically, the glass plate laminate is accommodated above the base portion of the pallet, and the load of the glass plate laminate via a buffer below the glass plate laminate. The present invention relates to a technology for improving a glass plate package in which a glass plate receiving portion for receiving a glass plate is disposed.

  As is well known, various types of glass plates represented by glass substrates for flat panel displays (FPD) such as liquid crystal displays, plasma displays, field emission displays (including surface emission displays) and electroluminescence displays have recently become large-sized. The actual situation is that promotion is being promoted. As an example, a glass substrate for a liquid crystal display has a side length exceeding 2000 mm and a plate thickness of 0.7 mm has become widespread and has become thinner. Since such a large and thin glass plate is easily damaged, it is extremely difficult to handle it when it is packed and transported. In particular, the packaging form is regarded as important.

  This type of glass plate packaging is to stack a plurality of glass plates in a flat position (substantially horizontal position) as a glass plate laminate housed above the base of the pallet and pack in this state. Is advantageous (see, for example, Patent Documents 1 to 3). In other words, when this type of glass plate is stacked and packed in a vertical posture (tilted posture), the glass plate is damaged during packaging and transportation due to stress concentration occurring near the lower side of the glass plate. Invite. On the other hand, if this type of glass plate is stacked and packaged in a flat position, the glass plate is supported by surface contact, so stress concentration occurs near some sides of the glass plate as described above. From this point of view, it can be expected to suppress breakage of the glass plate.

  By the way, as a transportation means of the glass sheet packaged body in which the glass sheet laminate is accommodated flat on the base part of the pallet, air transportation, sea transportation, truck transportation, or handling with a forklift can be mentioned. However, in all these cases, since the impact in the vertical direction, the front-rear direction, and the left-right direction acts continuously on the glass plate package, the stacking posture of the glass plate laminate is broken and applied to each glass plate. It becomes a factor which increases surface pressure.

  In this case, considering that the occurrence of impact due to the external transportation environment cannot be avoided, the generated impact is appropriately absorbed by the structural surface of the glass plate package, and each glass plate is adversely affected. It is important to avoid it. Moreover, each glass plate in the glass plate package must be accurately held in its loading position after transportation, and the glass plate is displaced from front to back and left and right due to impacts in the front and rear direction and the left and right direction. In such a case, an error or the like is caused when the glass plate is taken out, so that it cannot be put into the production line.

  Therefore, according to Patent Document 4, the glass plate laminate is accommodated flatly in a plate-like body storage box (glass plate storage box), and the glass plate storage box is mounted on a pedestal (base) having an upholstery material. A packaging form is disclosed in which a vibration absorbing material is interposed between the bottom plate of the glass plate storage box and the base portion (upholstery material). According to this packing form, the action of the vibration absorbing material absorbs the impact in the vertical direction applied to the glass plate laminate during transportation and the like, and the front and rear, left and right of each glass plate by the inner surface of the glass plate storage box It can be expected to prevent misalignment.

  By the way, the glass plate package described in the above-mentioned Patent Document 4 is configured to receive the load of the glass plate laminated body on the base part upper member through the shock absorber. That is, the glass plate receiving part which receives the load of a glass plate laminated body is comprised by the upper material arrange | positioned on the upper surface of the base part which consists of a frame body.

  If the shock absorber is simply placed on the upper surface of the upper material without any ingenuity, it is necessary to increase the number of laminated glass plates in order to increase the loading efficiency of the glass plate package. In other words, there arises a problem that the upper material is bent and deformed due to an increase in the weight of the glass plate laminate.

  More specifically, since the load of the glass plate laminate must be received through the shock absorber even by the part where the frame material of the frame body does not exist below the upper material, There is a possibility that the rigidity and strength may be insufficient, and due to this, there is also a drawback that the support mode of the glass plate laminate is distorted.

  In view of the above circumstances, the present invention appropriately performs the impact mitigating action on the glass plate laminate after sufficiently securing the rigidity and strength of the glass plate receiving portion that receives the load of the glass plate laminate via the buffer. It is a technical object to provide a glass plate package that can be used and that does not cause an unreasonable weight increase.

  The present invention, which was created to solve the above technical problem, accommodates a glass plate laminate formed by laminating a plurality of glass plates in a flat position above a base portion of a pallet, and the glass In a glass plate package in which a glass plate receiving portion that receives a load of the glass plate laminated body via a buffer is disposed below the plate laminated body, the glass plate receiving portion assembles a frame material in a lattice shape The buffer body is characterized by having a buffer base material disposed on the upper surface in a manner along the upper surface of each frame member of the frame body. Here, the “buffer” is synonymous with the shock absorber. The “glass plate receiving portion” may be a part of the base portion (upper surface portion), or may be a component different from the base portion. In addition, the above-mentioned “arranged on the upper surface in a manner along the upper surface of each frame member of the frame body” means that another member (for example, an upper material or the like) is interposed on the upper surface of each frame member of the frame body. It also includes the case where it is placed on it in the state where

  According to such a configuration, since the buffer base material of the buffer body is disposed on the top surface of the frame body of the frame body that forms the skeleton of the glass plate receiving portion, and on the top surface, the glass plate The load of the laminated body is received by each frame member of the frame body through the buffer base material. Accordingly, the glass plate receiving portion that receives the load of the glass plate laminate has sufficient rigidity and strength, and it becomes possible to avoid the support mode of the glass plate laminate becoming distorted. . Furthermore, since the frame body is an assembly of frame materials in a grid shape, if a buffer base material is placed at an appropriate position on the upper surface of the grid frame material, an appropriate impact mitigating action is secured on the glass plate laminate. It becomes possible to do. In addition, since the frame body is effectively used for the arrangement of the buffer base material, the upper material can be made thin, light, or unnecessary, so that it is possible to avoid an undue weight increase of the glass plate package.

  In this case, the said buffer base material can be comprised with a some buffer base piece, and these some buffer base pieces can be arranged mutually spaced apart.

  In this way, it is only necessary to arrange a plurality of buffer base pieces corresponding to only appropriate positions of each frame member of the frame body, so that waste of the buffer material is avoided and the load of the glass plate laminate is reduced. The receiving mode can be a desired mode. In this case, it is not necessary for all of the plurality of buffer base pieces to be separated from each other, and some of them may be arranged in series.

  In such a configuration, the plurality of buffer base pieces can be arranged with a uniform number density over substantially the entire area of the glass plate receiving portion. Here, the “number density” means the density of the number of buffer base pieces existing per unit area.

  In this way, when a non-large glass plate or a non-thin glass plate that is not easily deformed flexibly is laminated and subjected to the load, the glass plate laminate is maintained in a horizontal posture and supported by a plurality of buffer base pieces. It becomes possible.

  The plurality of buffer base pieces may be arranged such that the number density of the central portion of the glass plate receiving portion is large and the number density gradually decreases as it moves to the outer peripheral side.

  That is, when the glass plate is large and thin, if the plurality of buffer base pieces are arranged so that the number density is uniform, the glass plate laminate is likely to be bent and deformed by its own weight, particularly in the central portion. There is a tendency to deform so that it sinks. Therefore, as described above, if the plurality of buffer base pieces are arranged so that the number density gradually increases as they move to the central portion, the surface pressure received by each buffer base piece from the glass plate laminate is equal. This is advantageous in supporting this type of glass plate laminate in a horizontal position.

  Further, the plurality of buffer base pieces are symmetrical on both sides with respect to the center line between the two opposite side edges of the glass plate receiving portion, and the number density gradually increases as the distance from the center line increases. It may be arranged as follows.

  In this way, when the glass plate laminate is placed on top of the plurality of buffer base pieces, the compression amount of the buffer base piece near the center line is large, and the compression amount of the buffer base piece as it moves away from the center line Therefore, the glass plate laminate is placed in a curved shape so as to be recessed at the center between the two opposing side surfaces. Thereby, it becomes difficult to produce the horizontal shift | offset | difference to the curve direction of a glass plate laminated body, and it can hold | maintain the stable position with respect to the impact of a horizontal direction.

  Further, the plurality of buffer base pieces may have two or more different elasticity of each buffer base piece.

  If it does in this way, it will become possible to change the degree of compression deformation of a buffer base piece according to the difference in the field of a glass plate receiving part. For example, if a buffer base piece that is difficult to compress and deform is arranged in the central region of the glass plate receiving portion, and a buffer base piece that is easy to compress and deform as it moves to the outer peripheral side region, the above-mentioned large thin glass plate It is possible to cope with the deformation at the center of the laminate. Also, a buffer base piece that is easily compressed and deformed is disposed in the region near the center line between the two opposite side edges of the glass plate receiving portion, and a buffer base piece that is difficult to compress and deform as the distance from the center line is increased. For example, as described above, the glass plate laminate can be placed in a curved manner so that the center portion between the two side surfaces facing each other is depressed.

  Further, the plurality of buffer base pieces may be composed of a laminate of two or more layers in which each buffer base piece has two or more kinds of elasticity.

  If it does in this way, it will become possible to support a glass plate layered product in the state stabilized very much to vibration. In other words, a structure having an anti-vibration mechanism may resonate at a specific vibration frequency (natural frequency) and amplify the vibration, but as a laminate of two or more layers having two or more kinds of elasticity. If each buffer base piece is configured, the vibration isolation mechanism can have a damping function, and vibration amplification due to resonance can be prevented.

  On the other hand, the buffer base material can be composed of a plurality of buffer base pieces, and the plurality of buffer base pieces can be connected to each other and arranged.

  In this way, since the number of buffer base pieces can be reduced by making each buffer base piece a long buffer base piece extending along each frame member, the buffer base pieces can be fixed or adhered. This makes it possible to save work and improve workability. In this case, it is not necessary for all of the plurality of buffer base pieces to be connected to each other, and some of them may be arranged separately.

  In the above configuration, it is preferable that the width-direction dimension of the buffer base piece is substantially the same as or shorter than the width-direction dimension of the upper surface of the frame member.

  If it does in this way, it will become possible to fix or stick a buffer base piece reliably and appropriately using the upper surface of each frame material of a frame body effectively.

  In the above configuration, it is preferable that the buffer body further includes a flexible sheet arranged so as to cover the upper portions of the plurality of buffer base pieces. Here, the “flexible sheet” may be one that performs a buffering action or may not perform a buffering action, but it is the buffer base piece that performs the main buffering action to the last. Therefore, it is preferable that the flexible sheet has higher rigidity or hardness than the buffer base piece.

  In this case, the buffer base piece exists because the flexible sheet covers the upper portions of the plurality of buffer base pieces, and the buffer base pieces are arranged in a manner along the upper surface of each frame member of the frame body. A plurality of holes or recesses that are not present are covered with the flexible sheet, and the support of the lower end surface of the glass plate laminate can be satisfactorily performed over the entire region.

  As described above, according to the present invention, since the load of the glass plate laminate is received by each frame member of the frame body via the buffer base material, as the glass plate receiving portion that receives the load of the glass plate laminate. Thus, sufficient rigidity and strength are provided, and it becomes possible to avoid the support mode of the glass plate laminate from becoming distorted. Furthermore, since the frame body is an assembly of frame materials in a grid shape, if a buffer base material is placed at an appropriate position on the upper surface of the grid frame material, an appropriate impact mitigating action is secured on the glass plate laminate. It becomes possible to do. In addition, since the frame body is effectively used for the arrangement of the buffer base material, the upper material can be made thin, light, or unnecessary, so that it is possible to avoid an undue weight increase of the glass plate package.

  FIG. 1 is a perspective view showing the overall configuration of the glass plate package according to the first embodiment of the present invention. As shown in the figure, the glass plate package 1 has a plane corresponding to the size of the glass plate on the upper surface of the base portion 3 having a substantially rectangular plan view as a component of the pallet 2. A glass plate receiving portion 4 having a substantially rectangular shape is fixed integrally. The glass plate receiving portion 4 is formed to rise (raise) from a position on the inner side of the periphery of the upper surface portion of the base portion 3, and therefore, the vicinity of the periphery of the upper surface portion of the base portion 3 extends over the entire periphery. The predetermined width portion is exposed. A buffer body 5 is laid on the upper surface portion of the glass plate receiving portion 4 over substantially the entire area, and a plurality of (for example, 50 to 300) glasses are provided on the upper surface portion of the buffer body 5. The glass plate laminated body 6 which mounts protective sheets, such as a slip sheet and a foamed resin sheet, between the board | substrates is mounted. In addition, in the uppermost part of the glass plate laminated body 6, the foam sheet (buffer material or cushion material) which is thicker and harder than that is stacked on the upper surface of the protective sheet.

  Further, the lower end portions of the plurality of press plates 7 are detachably attached to the four side surfaces 4a of the glass plate receiving portion 4 using stoppers, and the glass plate laminate 6 is moved in the horizontal direction by these press plates 7. Is regulated. More specifically, two press plates 7 are attached to one side surface 4a of the glass plate receiving portion 4, and a total of eight press plates 7 are attached. The length of the body 6 is shorter than ½ of the entire circumferential length. Further, at the four corners of the base 3, specifically, at the four corners of the exposed portion of the upper surface of the base 3, support columns 8 that support the upper glass plate package when the glass plate package 1 is stacked in a plurality of stages. These columns 8 are detachably attached. In this case, all of the four support columns 8 are arranged in a state in which they do not protrude outward from the base portion 3 of the pallet 2. The base 3 is formed with a fork hole 9 into which a fork of a forklift is inserted and removed.

  Next, each element which comprises this glass plate package 1 is demonstrated in detail. FIG. 2 is a perspective view showing the base portion 3 and the glass plate receiving portion 4 of the pallet 2. As shown in the figure, the base portion 3 is a frame body in which a frame material 3b made of a metal such as an aluminum alloy is assembled in a lattice shape, and the glass plate receiving portion 4 is also a frame made of a metal such as an aluminum alloy. It is a frame body in which the material 4b is assembled in a lattice shape. And the base part 3 is longer than the glass plate receiving part 4 in the vertical dimension, the horizontal dimension and the height dimension, and the glass plate receiving part 4 is welded on the base part 3. Etc. are fixed integrally.

  FIG. 3 is a perspective view showing a state in which a buffer base material 5 a that is a constituent element of the buffer body 5 is laid on the upper surface of the glass plate receiving portion 4. As shown in the figure, the buffer base 5a is composed of a plurality of cube-shaped or rectangular parallelepiped-shaped (may be columnar or the like) buffer base pieces 5b, and the plurality of buffer base pieces 5b It is arranged so as to be scattered at an even arrangement density over substantially the entire region of the upper surface of the portion 4. Specifically, the plurality of buffer base pieces 5b are fixed or adhered to the upper surfaces of the frame members 4b while being spaced apart from each other in a manner along the upper surfaces of the frame members 4b of the frame body constituting the glass plate receiving portion 4. Has been. And these buffer base pieces 5b consist of buffer materials, such as rubber | gum, sponge rubber, resin, foamed resin, silicone, for example, The width direction dimension a of the buffer base piece 5b is the width direction dimension of the upper surface of the frame material 4b. It is substantially the same as or shorter than b. The number of buffer base pieces 5b is preferably 50 to 500, and more preferably 100 to 300.

  FIG. 4 is a perspective view showing the entire structure of the buffer body 5 laid on the upper part of the glass plate receiving portion 4. As shown in the figure, the buffer body 5 was laid so as to cover the entire area of the buffer base piece 5b on the plurality of buffer base pieces 5b and above the plurality of buffer base pieces 5b. It is comprised from the substantially rectangular flexible sheet 5c. The flexible sheet 5c is a relatively hard foamed resin sheet having a foaming ratio of 3 to 5 times capable of slightly buffering. In this embodiment, the flexible sheet 5c is a polypropylene three-fold foamed resin sheet (trade name: Paronia ( Registered trademark)).

  FIG. 5 shows a state in which the glass plate laminate 6 is placed on the buffer body 5 (strictly, the flexible sheet 5 c), and a plurality of press plates 7 are attached to the glass plate receiving portion 4. It is a perspective view shown. As shown in the figure, a glass plate laminated body 6 is placed on the upper portion of the buffer body 5 so as to receive a buffering action directly by a plurality of buffer base pieces 5b, and the buffer body 5 and the glass plate laminated body 6 A plurality of presser plates 7 are detachably attached to the side surface 4a of the glass plate receiving portion 4 so as to surround the outer side. In this case, each presser plate 7 is formed of a metal such as an aluminum alloy, and the glass plate is laminated such that no gap is formed between the inner surface of each presser plate 7 and the side surface 6 a of the glass plate laminate 6. A spacer having elasticity for suppressing horizontal displacement of the body 6 is attached. Further, these presser plates 7 are spaced apart from each other, and are longer than the widthwise dimension of the presser plate 7 at the center in the width direction of at least two side surfaces 6a of the glass plate laminate 6 facing each other. A gap S is formed. The horizontal dimension T1 (T2) between the side surface 4a of the glass plate receiving part 4 and the measurement surface 3a of the base part 3 is longer than the plate thickness dimension t1 of the presser plate.

  In such a state, the glass plate package 1 shown in FIG. 1 is obtained by erecting the pillars at the four corners of the base portion 3, and the periphery of the glass plate laminate 6 is covered with a stretch film or a film-like sheet. Thus, a fastening member can be used as needed. That is, a pressing force or a pulling force toward the base portion 3 side is applied to the uppermost portion of the glass plate laminate 6 using a fastening member such as a belt or a fastening bracket while utilizing the separation gap S between the holding plates 7. Various transports and the like are carried out in the state of being held. In this case, as shown in FIG. 6, a plurality of (two in the illustrated example) glass plate package 1 having the same configuration is manufactured, and the four support columns 8 in the lower glass plate package 1 are formed. The glass plate package 1 is integrated into a plurality of stages by fitting the convex portion 8a formed on the upper end into a recess (not shown) formed on the lower surface of the base 3 in the upper glass plate package 1. Various transports and the like can be performed in the state.

  According to the glass plate package 1 having the above-described configuration, the buffer base material 5a is in a mode along the upper surface of each frame member 4b of the frame body forming the skeleton of the glass plate receiving portion 4 and on the upper surface thereof. Since the plurality of buffer base pieces 5b constituting the same are arranged, the load of the glass plate laminate 6 is received by each frame member 4b of the frame body through the plurality of buffer base pieces 5b. Therefore, the glass plate receiving portion 4 that receives the load of the glass plate laminate 6 has sufficient rigidity and strength, and it is possible to avoid the support mode of the glass plate laminate 6 from becoming distorted. It becomes possible. Furthermore, since the frame body constituting the glass plate receiving portion 4 is an assembly of the frame material 4b in a lattice shape, if the buffer base piece 5b is disposed at an appropriate position on the upper surface of the lattice frame material 4b, the glass body It is possible to ensure an appropriate impact mitigating action on the plate laminate 6. In addition, since the frame body itself that constitutes the glass plate receiving portion 4 is effectively used for the arrangement of the buffer base pieces 5b, a high-rigidity and high-strength upholstery material is not required, and therefore, an unreasonable weight of the glass plate package 1 The increase can be avoided.

  FIG. 7 is a perspective view showing a main part of the glass plate package 1 according to the second embodiment of the present invention. The glass plate package 1 according to the second embodiment differs from the glass plate package 1 according to the first embodiment described above in that a plurality of buffer groups arranged on the upper surface portion of the glass plate receiving portion 4. The number density (number surface density) per unit area of the piece 5b is large at the central portion, and is gradually reduced as it moves to the outer peripheral side. That is, as in the case of the first embodiment described above, if the plurality of buffer base pieces 5b are arranged on the upper surface of the glass plate receiving portion 4 so that the number surface density of the entire region is equal, the glass plate is large. When it is thin, the glass plate laminate 6 tends to be bent and deformed by its own weight, and in particular, tends to be deformed so that the central portion sinks. Therefore, as in the case of the second embodiment, if the buffer base pieces 5b are arranged so that the number surface density gradually increases as it moves to the center, the individual buffer base pieces 5b are laminated on the glass plate. The surface pressure received from the body 6 can be made equal, and the glass plate laminate 6 can be supported while being maintained in a horizontal posture. Note that the number surface density of the buffer base pieces 5b in the central portion is 1.15 to 1.45 times, more preferably 1.3 times the number surface density of the buffer base pieces 5b in the peripheral region. It is preferable to form equal density bands on concentric circles. Since the other configuration is the same as that of the first embodiment described above, the common components in FIG.

  FIG. 8 is a perspective view showing a main part of the glass plate package 1 according to the third embodiment of the present invention. The glass plate package 1 according to the third embodiment differs from the glass plate package 1 according to the first embodiment described above in that the buffer base piece 5b has two or more types (three types in the illustrated example) of elasticity. Are arranged at a uniform number surface density over the entire area. Specifically, in the drawing, the buffer base piece 5b having a dark color at the center is hardly elastically deformed, and is easily elastically deformed as the color of the buffer base piece 5b becomes lighter as it moves to the outer peripheral side. It has become. Therefore, also in the third embodiment, similarly to the second embodiment described above, it is possible to maintain and support the glass plate laminate 6 placed on the top of each buffer base piece 5b in a horizontal posture. Become. Since the other configuration is the same as that of the first embodiment described above, the common components in FIG.

  FIG. 9 is a perspective view showing the overall configuration of the glass plate package 1 according to the fourth embodiment of the present invention. The glass plate packaging body 1 according to the fourth embodiment is different from the glass plate packaging body 1 according to the first embodiment described above in the central portion between the two side surfaces 6a facing the glass plate laminate 6 (see FIG. In the example, it is curved in such a manner that it is depressed at the center in the left-right direction) and is placed on the upper surface of the buffer body 5. The origin of the glass plate stack 6 being curved and mounted as described above is that, as shown in FIG. 10, the plurality of buffer base pieces 5 b arranged on the upper surface of the glass plate receiving portion 4 are made of glass plate holders. The center line in the left-right direction (the center line between the two opposite side edges 4c) X on the upper surface of the part 4 is symmetrical with respect to the left side and gradually becomes denser as the distance from the center line X increases. This is because they are arranged in a state of gradually increasing. Thus, in the state which arranged the several buffer base piece 5b in the upper surface part of the glass plate receiving part 4, and laid the flexible sheet 5c on it, it is a glass plate laminated body on the upper surface part of this flexible sheet 5c. 11, since the compression amount of the buffer base piece 5b near the center line X is large and the compression amount of the buffer base piece 5b decreases as the distance from the center line X increases as shown in FIG. The plate laminate 6 is curved in the above-described manner. If the glass plate laminated body 6 is curved and supported in this manner, lateral displacement in the bending direction is unlikely to occur, and a stable position can be maintained against a horizontal impact. Since the other configuration is the same as that of the glass plate package 1 according to the first embodiment described above, the same reference numerals are given to the common components in FIGS. 9 to 11 and the description thereof is omitted.

  FIG. 12: is a perspective view which shows the principal part of the glass plate package 1 which concerns on 5th Embodiment of this invention. The glass plate package 1 according to the fifth embodiment differs from the glass plate package 1 according to the first embodiment described above in that there are two or more individual buffer base pieces 5b (two types in the illustrated example). ) In the point of comprising a laminate of two or more layers having elasticity. If it does in this way, it will become possible to support the glass plate laminated body 6 in the state stabilized further with respect to the vibration. That is, in general, a structure having a vibration isolation mechanism may resonate at a specific vibration frequency (natural frequency) and amplify the vibration. However, as in the fifth embodiment, if individual buffer base pieces 5b are produced by combining buffer materials having different kinds of elasticity, the vibration isolation mechanism can have a damping function, and vibration caused by resonance can be obtained. Amplification can be prevented. Since the other configuration is the same as that of the glass plate package 1 according to the first embodiment described above, the common components in FIG.

  FIG. 13: is a perspective view which shows the principal part of the glass plate package 1 which concerns on 6th Embodiment of this invention. The glass plate package 1 according to the sixth embodiment differs from the glass plate package 1 according to the first embodiment described above in that each buffer base piece 5b is a frame body of the glass plate receiving portion 4. It has a form extending linearly along the upper surface of the frame member 4b to be configured, and the buffer base pieces 5b are all arranged in a connected state. In addition, each buffer base piece 5b may be spaced apart by shortening the buffer base piece 5b of a required location. If it carries out as mentioned above, each buffer base piece 5b can be attached to each frame material 4 of the frame body of the glass plate receiving part 4 with troublesome and labor-saving, and workability is improved. . Since the other structure is the same as that of the glass plate package 1 according to the first embodiment described above, the common components in FIG.

  In the above embodiment, a plurality of buffer base pieces 5b are used as the buffer base material 5a constituting the buffer body 5, but instead of this, a substantially rectangular shape corresponding to the upper surface portion of the glass plate receiving portion 4 is used. A single buffer base material obtained by removing a portion of the frame body where each frame member 4b does not exist from the buffer base material may be used.

  Further, in the above embodiment, the buffer body 5 is configured by the buffer base material 5 a or the plurality of buffer base pieces 5 b and the flexible sheet 5 c, but the flexible sheet 5 c is used as a component of the buffer body 5. May be eliminated.

  Furthermore, in the above embodiment, the glass plate laminate 6 is placed on the upper surface portion of the buffer 5. However, for example, the glass plate laminate 6 is accommodated in a box having a bottom plate and a side plate, and the buffer The box may be placed on the upper surface of the body 5.
