Description

  The present invention relates to a glass plate package, and more particularly, to an improvement technique for a glass plate package in which a glass plate laminate is accommodated above a base portion of a pallet.

  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.

  However, if the glass plate storage box described in the above-mentioned Patent Document 4 is easily deformed or loses its shape, the function as the storage box is impaired and the original operational effects cannot be obtained. Therefore, it must be rigid. Therefore, the glass plate laminate is directly supported by the glass plate storage box made of a rigid body, and this glass plate storage box is a direct object that receives the vibration absorbing action by the vibration absorbing material. .

  Therefore, in this packing form, the weight of the glass plate laminated body is light in order to increase the loading efficiency of the glass plate packing body, regardless of whether the weight of the glass plate laminated body is light in relation to the vibration absorption capacity with respect to the glass plate storage box. Considering the fact that it is necessary to increase the number of laminated plates, it is impossible to avoid breakage of the glass plate, no matter how vibration absorption is performed on the glass plate storage box. In other words, when the number of glass plates stacked is increased, it is necessary to strengthen the shock absorbing function to meet the increase in the weight of the glass plate laminate, and the glass plate storage box also has a more rigid structure. There is a need.

  Therefore, the pressure or stress received by the glass plate laminate having increased weight from the bottom plate of the glass plate containing box with increased rigidity increases synergistically, and in particular, the surface of the glass plate present in the lower layer portion of the glass plate laminate. The pressure becomes unreasonably large, and the probability of occurrence of breakage of the glass plate becomes extremely high. As a result, in this packing form, it is impossible to cope with an increase in the number of laminated glass plates to meet the recent demand for reduction in transportation costs.

  Patent Documents 2 and 3 disclose that the shock absorber is attached to the outer bottom surface of the glass plate storage box and the shock absorber is attached to the inner bottom surface of the glass plate storage box. However, since all these glass plate storage boxes are connected to each other without any gaps, the rigidity of the storage box is increased and the depth is increased in order to meet the demand for an increase in the number of glass plates loaded as described above. If it is deepened, fatal defects such as a significant increase in weight of the glass plate package and an unreasonable waste of materials will occur.

  In view of the above circumstances, the present invention is capable of appropriately mitigating the impact acting on the glass plate laminate even when the number of laminated glass plates is increased, and is capable of significantly increasing the weight and improper material. It is a technical problem to provide a glass plate package capable of suppressing generation of waste and the like.

  The present invention, which was created to solve the above technical problem, is configured to accommodate a glass plate laminate formed by laminating a plurality of glass plates in a flat position above the base portion of the pallet. In the glass plate package, a glass plate receiving portion having a size corresponding to the size of the glass plate is disposed on the upper portion of the base portion, and the upper portion of the glass plate receiving portion covers substantially the entire area thereof. The buffer plate is laid, the glass plate laminate is placed on the buffer, and the glass plate is positioned on the glass plate receiving portion on the outer side of the buffer and the glass plate laminate. It is characterized in that a plurality of press plates that regulate the horizontal movement of the laminated body are attached to be separated from each other. Here, the “buffer” is synonymous with the shock absorber.

  According to such a configuration, the buffer plate is laid on the upper portion of the glass plate receiving portion on the base portion, and the glass plate laminate is placed on the upper portion of the buffer body. Directly receives a buffering effect by the body. Therefore, the impact generated in the glass plate laminate during transportation or the like is directly mitigated by the buffer, and the impact that causes the glass plate to breakage does not act. Furthermore, even when the number of laminated glass plates is increased, the buffer body deforms more flexibly as the pressure generated between the glass plate laminate and the buffer body increases, and the adjacent buffer material is the same. When the glass surface pressure is dispersed by being deformed to the extent, local stress concentration does not act on the glass plate, and the probability of occurrence of breakage of the glass plate is reduced. In addition, since a plurality of press plates that regulate the movement of the glass plate laminate in the horizontal direction are mounted apart from each other, the entire circumference of the glass plate laminate is surrounded by the side surface without any gap as in the case of a box. Compared with the case where it is, the weight is reduced and the waste of material does not occur. Such an advantage is remarkably obtained when the presser plate is raised with an increase in the number of laminated glass plates.

  In this case, it is preferable that the plurality of presser plates are detachably attached to the glass plate receiving portion.

  In this way, the presser plate can be removed at the time of loading and unloading the glass plate laminate, so that it does not interfere with the loading and unloading work and the workability is improved.

  Moreover, it is preferable that the value of the sum total of the dimension of the width direction of these some pressing plate is less than 1/2 of the circumferential direction full length of the said glass plate laminated body.

  In this way, the weight reduction and the avoidance of material waste due to the plurality of the above-described presser plates being separated from each other can be further ensured.

  In the above configuration, it is preferable that the glass plate receiving portion is formed upright from a position on the inner side of the upper surface periphery of the base portion.

  In this way, a space is formed in the vicinity of the peripheral edge of the upper surface of the base portion, and this space can be effectively used for a mounting space for the pressing plate, a mounting space for a column to be described later, and the like.

  In this case, it is preferable that the plurality of presser plates are respectively attached to the side surfaces of the glass plate receiving portion.

  In this way, each presser plate can be configured so as not to protrude toward the glass plate receiving part, so that the glass plate laminate is appropriately surrounded by each presser plate and hinders horizontal movement of the glass plate laminate. It becomes possible to regulate without any loss.

  Moreover, it is preferable that the separation dimension in the horizontal direction of the side surface of the said glass plate receiving part and the side surface of the said base part is longer than the plate | board thickness dimension of the said holding plate.

  In this way, the presser plate does not protrude outward from the base part, so that the glass plate package can be compactly accommodated, and the problem that the presser plate becomes an obstacle during transportation or the like does not occur.

  Furthermore, it is preferable to stand upright at the four corners of the base portion to support the upper glass plate package when stacking the glass plate package in a plurality of stages.

  In this way, it is possible to stack the glass plate packages in multiple stages during air transportation, sea transportation, truck transportation, etc., and avoid the problem that the upper space is wasted. can do.

  The glass plate receiving part is preferably a frame body in which frame members are assembled in a lattice shape, and the upper surface of each frame member of the frame body is preferably the upper surface of the glass plate receiving part.

  In this way, since the upper surface of the frame that forms the skeleton of the glass plate receiving portion is the upper surface of the glass plate receiving portion, sufficient rigidity and strength necessary to receive the weight of the glass plate laminate are sufficiently secured. It becomes possible to do.

  Further, the buffer body includes a buffer base material disposed on the upper surface in a form along the upper surface of each frame member of the frame body, and a flexible sheet disposed to cover the upper part of the buffer base material. It is preferable that it is comprised from these. Here, “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 placed on the upper surface of each frame member of the frame body. It also includes the case where it is placed on it in a state of being interposed. In addition, the “flexible sheet” may be one that performs a buffering action or may not perform a buffering action, but it is preferably a buffer base material 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 material.

  In this case, since the flexible sheet covers the upper portion of the buffer base material, the buffer base material does not exist because the buffer base material is arranged in a mode along the upper surface of each frame member of the frame body. The plurality of holes or recesses 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.

  In this case, the buffer base material is preferably composed of a plurality of buffer base pieces, and the plurality of buffer base pieces are arranged so as to be separated from or connected to each other.

  If it does in this way, what is necessary is just to let each buffer base piece be a columnar body of a column shape or a prism shape. Preferably, the shape may be a cubic shape, a rectangular parallelepiped shape, or a line-shaped rectangular parallelepiped shape, and the production of the buffer base material is greatly facilitated, and a plurality of buffer base pieces are fixed or attached to the upper surface of each frame member. Work is also facilitated.

  Moreover, it is preferable that the width direction dimension of the said buffer base piece is substantially the same as the width direction dimension of the upper surface of the said frame material, or it is shorter than it.

  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.

  As described above, according to the present invention, the impact generated in the glass plate laminate during transportation or the like is directly mitigated by the buffer, and the impact that causes the glass plate to break does not work, and the glass Even when the number of laminated plates is increased, the buffer body deforms more flexibly as the pressure generated between the glass sheet laminate and the buffer body increases, and the adjacent buffer material deforms to the same extent. By dispersing the glass surface pressure, local stress concentration does not act on the glass plate, and the probability of breakage of the glass plate is reduced. In addition, since a plurality of press plates that regulate the horizontal movement of the glass plate laminate are mounted apart from each other, the entire circumference of the glass plate laminate is not spaced by the side of the box as in the case of a box. Compared to the surrounding case, the weight can be reduced and the material is not wasted.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. In the present embodiment, the glass plate is a substantially rectangular glass substrate for FPD (particularly for a liquid crystal display) (vertical dimension is 1000 to 3500 mm, lateral dimension is 1000 to 3500 mm, and plate thickness is 0.3 to 0.00. 7 mm).

  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 each side surface 4a of the glass plate receiving portion 4, and a total of eight press plates 7 are attached. The total size of the eight press plates 7 in the width direction is the glass plate laminate. 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, a plurality of buffer base pieces 5b are provided on the upper surface portion of the glass plate receiving portion 4 integrally fixed on the base portion 3 of the pallet 2. Since the buffer body 5 composed of the flexible sheet 5 c is laid and the glass plate laminate 6 is placed on the upper surface of the buffer body 5, the glass plate laminate 6 has a buffering action by the buffer body 5. Receive directly. Therefore, the impact generated in the glass plate laminate 6 during transportation or the like is directly mitigated by the buffer body 5, and the probability of occurrence of breakage of the glass plate is greatly reduced. Further, even when the number of laminated glass plates is increased, the buffer body is more flexibly deformed as the pressure generated between the glass plate laminate 6 and the buffer body 5 increases, and the adjacent buffer material Since the glass surface pressure is dispersed by deforming to the same extent, local stress concentration does not act on the glass plate, and the probability of occurrence of breakage of the glass plate is effectively reduced. In addition, since a plurality of press plates 7 that regulate the horizontal movement of the glass plate laminate 6 are mounted apart from each other, the entire circumference of the glass plate laminate 6 is a box with no gap as in the case of a box. Compared to the case of being surrounded by the side surface, the weight is reduced and the material is not wasted. Moreover, since the presser plate 7 is detachably attached, the presser plate 7 can be removed when the glass plate laminated body 6 is unloaded, and the workability can be greatly improved.

  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, a substantially rectangular buffer base corresponding to the upper surface portion of the glass plate receiving portion 4 is used. A single buffer base material may be used in which a portion where the frame members 4b of the frame body are not present is removed from the material.

  In order to confirm the effect of the glass plate package 1 described above, the present inventors made a comparison between Examples 1 to 4 of the present invention and a comparative example as follows.

  Example 1 of the present invention is as follows. First, the base part 3, the glass plate receiving part 4, the presser plate 7 and the support column 8 of the pallet 2 are made of an aluminum alloy, and basically the glass plate package 1 having the configuration shown in FIG. . Secondly, as the glass plate laminate 6, 200 glass plates having a horizontal dimension of 2200 mm, a vertical dimension of 2500 mm, and a thickness of 0.7 mm are laminated, and a foamed resin sheet is interposed between these glass plates. Disguised. Thirdly, 200 buffer base pieces 5b made of sponge rubber having a horizontal dimension of 70 mm, a vertical dimension of 70 mm, and a thickness of 30 mm are used in the second embodiment shown in FIG. The density was arranged at 1.3 times the number surface density of the peripheral part. Fourth, as the flexible sheet 5c, a polypropylene three-fold foamed resin sheet (trade name: Palonia (registered trademark)) having a thickness of 10 mm was used.

  In Example 2 of the present invention, paper was interposed between the glass plates of the glass plate laminate 6, and the other configurations were the same as those in Example 1 described above.

  Example 3 of the present invention is as follows. First, the base part 3, the glass plate receiving part 4, the presser plate 7, and the support column 8 of the pallet 2 are made of aluminum alloy, and basically the glass plate package 1 having the configuration shown in FIG. . Secondly, as the glass plate laminate 6, 100 glass plates having a horizontal dimension of 2200 mm, a vertical dimension of 2500 mm, and a thickness of 0.7 mm are laminated, and a foamed resin sheet is interposed between these glass plates. Disguised. Third, 270 buffer base pieces 5b made of sponge rubber having a horizontal dimension of 55 mm, a vertical dimension of 55 mm, and a thickness of 30 mm were arranged in the form of the fourth embodiment shown in FIG. Fourth, as the flexible sheet 5c, a polypropylene three-fold foamed resin sheet (trade name: Palonia (registered trademark)) having a thickness of 10 mm was used.

  In Example 4 of the present invention, paper was interposed between the glass plates of the glass plate laminate 6, and the other configurations were the same as those of Example 3 above.

  A comparative example is as follows. First, as shown in FIG. 14, the base portion 3 of the pallet 2 and the protruding portion 3x above the pallet 2 are made of an aluminum alloy, and both are integrated by welding (same as the structure shown in FIG. 2). A grid-like glass plate receiving portion 4 made of aluminum alloy was installed above the protruding portion 3x via a vibration-proof rubber 11, and a single rubber sheet 12 having a thickness of 5 mm was laid on the upper surface portion. Second, as shown in FIG. 15, as the glass plate laminate 6, 200 sheets of glass plates having a horizontal dimension of 2200 mm, a vertical dimension of 2500 mm, and a thickness of 0.7 mm are interposed between each other. The glass plate laminate 6 was stacked and placed on the upper surface of the rubber sheet 12. Thirdly, the holding plate 7 that restricts the horizontal movement of the glass plate laminate 6 is fixed to the side surface of the glass plate receiving portion 4, and pillars (not shown) are erected at the four corners of the base 3. Finally, a glass plate package 1 was obtained.

  About the above Examples 1-4 and the comparative example, the same kind of glass plate package was loaded on the loading platform of the truck in three rows and transported. The results are shown in Table 1 below.

  As a result of the above-mentioned truck transportation, if Table 1 is taken into consideration, all of Examples 1 to 4 did not cause a lateral shift or breakage of the glass plate, but only the comparative example was a glass plate in each glass plate package. The lowermost glass plate of the laminate was damaged. This breakage position coincided with the position of the frame member of the glass plate receiving portion 4. In the comparative example, the damage was eliminated by setting the number of laminated glass plates to 150, and the anti-vibration function was not exhibited by reducing the number of sheets to 100, and three damages occurred again.

  Next, in Examples 1 to 4 and Comparative Example described above, the same type of glass plate package was loaded in three rows in three rows on a truck bed and transported. The results are shown in Table 2 below.

  As a result of truck transportation in this case, if Table 2 was taken into consideration, none of Examples 1 to 4 caused lateral displacement and breakage of the glass plate, but only the comparative example caused frequent breakage and nine cases. The total number of damaged sheets in the glass plate package was 11, and all the damaged positions were near the lowest position of the glass plate laminate. Moreover, the weight of the base part connected with the other glass plate package was increased substantially by stacking in the comparative example, and thereby the vibration-proof function was considerably lowered. For this reason, vibration generated in the glass plate laminate could not be absorbed, and a lateral displacement of the glass plate was generated by 8 mm. In this case, even if the number of stacked glass plates was reduced to 100 to 150, the number of breakage was reduced, but it was impossible to prevent appropriately. On the other hand, in Examples 1-4, each characteristic was utilized and the lightweight and heavy glass plate laminated body of 100 sheets and 200 sheets was able to be conveyed safely.
