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 considered advantageous. 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, the glass plate package is continuously subjected to vibrations or impacts in the vertical direction, the front-rear direction, and the left-right direction. It is important to obtain an effect.

  So, according to patent document 1, the packaging form which mounted the glass plate laminated body on the upper part of the base via the buffer is disclosed. Furthermore, according to Patent Document 2, the glass plate laminate is accommodated flatly in a plate-like object accommodation box (glass plate accommodation box), and the glass plate accommodation box is placed above the pedestal having the upper material. And a packaging form in which a vibration absorbing material is interposed between the bottom plate of the glass plate storage box and the base portion (upper material). According to the packing form as described above, it is expected that the vibration or impact in the vertical direction applied to the glass plate laminate during transportation or the like is absorbed by the action of the buffer body or the vibration absorbing material.

  By the way, as disclosed in Patent Documents 1 and 2, a glass plate package having a vibration isolating structure on which a glass plate laminate is loaded is separated from an upper portion with a buffer body (vibration absorbing material) as an anti-vibration structure as a boundary. By dividing into lower parts, the influence of vibration and impact can be considered. In that case, the natural vibration of the upper part (the part where the glass plate laminate is present) is usually designed to be a low frequency based on the general frequency in this field. Therefore, if low-frequency vibration (or shock) close to the natural vibration of the upper part is input to the lower part, it will be difficult to absorb the low-frequency vibration with the vibration-proof structure, and the vibration will be effective. This leads to a situation in which it is not absorbed and propagated directly to the glass plate laminate.

  Taking this into account, it is convenient to input high-frequency vibrations clearly different from the upper part into the lower part of the glass plate package. It is effective for anti-vibration to reduce the inertia by reducing the weight of the portion and, in particular, by appropriately reducing the weight of the lower portion relative to the weight of the upper portion.

  However, in the glass plate package disclosed in Patent Document 1, since the upper surface portion of the base also serves as the glass plate receiving portion, the base and the glass plate receiving portion are integrated, and disclosed in Patent Document 2. In the made glass plate package, the pedestal and the glass plate receiving portion are integrated because the upper surface portion of the pedestal also serves as the glass plate receiving portion. Therefore, since both the base described in Patent Document 1 and the base described in Patent Document 2 need to have a rigid structure, it is difficult to reduce weight and reduce inertia. .

  Due to this, low-frequency vibrations close to the natural vibrations of the upper part when the buffer body and the vibration absorbing material are used as boundaries are input from both the base and the pedestal. The low frequency vibrations are not properly absorbed by the respective actions of the buffer and the vibration absorbing material, but are propagated as they are to the glass plate laminate, causing the glass plate to break or break.

  And, if such problems are reflected in reality that it is necessary to increase the number of laminated glass plate laminates in order to increase the loading efficiency of the glass plate package, the above-mentioned base and pedestal are each made of a rigid rigid structure. This has become even more prominent due to their increased weight and increased inertia.

  In the present invention, in view of the above circumstances, a high-frequency vibration that is clearly different from the natural vibration of the upper part is input to the lower part of the lower part of the shock absorber having an appropriate rigid structure. Thus, it is a technical problem to provide a glass plate package capable of ensuring a good vibration isolation function.

The present invention, which was created to solve the above technical problem, has a structure in which a glass plate laminate formed by laminating a plurality of glass plates in a flat position is placed above the base portion of the pallet. A glass plate receiving portion that receives the load of the glass plate laminate is disposed at the top of the portion, and the glass plate laminate is placed on the glass plate receiving portion via a buffer. In the glass plate package,
The base part and the glass plate receiving part are separated, the horizontal movement of the glass plate receiving part with respect to the base part is restricted, and the glass plate receiving part is vertically moved on the upper surface part of the base part. It is characterized by being placed in an edge-cut state that can vibrate freely in the direction. Here, the above “buffer” is synonymous with the shock absorber.

  According to such a configuration, when the glass plate package is divided into the upper part (including the glass plate laminate) and the lower part with the buffer body as a boundary, the lower part is the base part. After being separated from the glass plate receiving portion, the horizontal movement of the glass plate receiving portion with respect to the base portion is restricted. And the glass plate packing body is placed on the base portion in an edge-cut state in which the glass plate receiving portion can freely vibrate in the vertical direction, and the glass plate laminated on the upper portion of the glass plate receiving portion via a buffer. The body is placed. In such a state, the lower part supporting the load of the upper part of the glass plate package can secure sufficient rigidity as a whole, and the glass plate receiving part of the lower part can be Since it is separated from the base portion, the weight is reduced and the inertia is reduced. As a result, when vibration or impact is input to the lower part of the glass plate package during transportation, etc., the glass plate receiving part, which is a part of the lower part, has a high frequency component of vibration transmitted from the base part. Therefore, it becomes easier to vibrate and low frequency components are difficult to convey. For this reason, the glass plate receiving portion vibrates at a high frequency that is clearly different from the low frequency natural vibration of the upper portion. As a result, high-frequency vibrations input to the glass plate receiving part are easily absorbed by the vibration isolating structure consisting of the buffer, and are hardly propagated to the glass plate laminate above it, and the glass plate is broken or damaged. Is significantly reduced. In this case, since the glass plate receiving portion is placed in a state in which the horizontal movement is restricted with respect to the base portion, the glass plate receiving portion can freely vibrate in the vertical direction on the base portion. Regardless, the lateral displacement is appropriately suppressed. In addition, it is preferable that the buffer body is directly laid on the upper part of the glass plate receiving portion, and further, the glass plate laminate is directly placed on the buffer body, or the glass plate laminate is the buffer body. It is preferable to be disposed so as to directly receive the buffering action. However, the glass plate laminate is accommodated in the internal space of the box, and the glass plate is laminated by another structure, such as arranging a buffer between the bottom plate of the box and the glass plate receiving portion. The body may be buffered by the buffer.

  From the above viewpoint, the glass plate package is divided into an upper portion including the glass plate laminate, and a lower portion including the base portion and the glass plate receiving portion, with the buffer body as a boundary, When vibration or impact is input to the lower part, the glass plate receiving part is preferably configured to vibrate at a high frequency clearly different from the low frequency natural vibration of the upper part.

  In this case, the weight of the glass plate receiving part is preferably lighter than the base part.

  If it does in this way, the glass plate receiving part isolate | separated from the base part in the lower site | part of a glass plate package can be made lightweight significantly, and the inertia can be made very small. Therefore, the glass plate receiving part which is a part of the lower part of the glass plate package is more easily vibrated with respect to the high frequency component of vibration transmitted from the base part, and the low frequency natural vibration of the upper part is Will vibrate at a more distinctly different high frequency, so that the vibration is more appropriately absorbed by the vibration isolating structure consisting of the buffer, and propagates to the glass plate laminate above it and the glass plate resulting therefrom Occurrence of cracks and breakage is further reliably reduced.

  In the above configuration, it is preferable that a plurality of press plates for restricting the movement of the glass plate laminate in the horizontal direction are attached to the glass plate receiving portion so as to be separated from each other.

  In this way, the lateral displacement of the glass plate laminate on the glass plate receiving portion is suppressed by the plurality of press plates, and a plurality of these press plates are separated from each other. Thus, compared with the case where the entire periphery of the glass plate laminate is surrounded by the side surface without any gaps, the weight can be reduced and the waste of materials 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 addition, it is preferable that the plurality of press plates are detachably attached to the glass plate receiving portion, and if this is done, the press plates can be removed when the glass plate laminate is unloaded. Therefore, the workability is improved without interfering with the loading / unloading work. Further, the sum of the width direction dimensions of the plurality of presser plates is preferably less than ½ of the total circumferential length of the glass plate laminate, and if this is done, the above plurality of presser plates It is possible to further reduce the weight and avoid waste of materials by separating them from each other.

  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 a plurality of press plates are respectively attached to the side surfaces of the glass plate receiving portion. If this is done, each press plate may be configured not to protrude to the glass plate receiving portion side. Therefore, the glass plate laminate can be appropriately surrounded by the press plates, and the horizontal movement of the glass plate laminate can be regulated without hindrance. Further, the horizontal dimension between the side surface of the glass plate receiving portion and the side surface of the base portion is preferably longer than the plate thickness dimension of the press plate. Since it does not protrude outward from the base part, the glass plate package can be compactly accommodated, and there is no problem that the holding plate becomes an obstacle during transportation or the like. Furthermore, it is preferable to erected support columns that support the upper glass plate package when stacking the glass plate packages in a plurality of stages at the four corners of the base part. During transportation or truck transportation, it is possible to stack the glass plate packages in a plurality of stages and load them in the transportation space, thereby avoiding the problem that the upper space is wasted. Also in this case, it is preferable that each support | pillar does not protrude to the outward side rather than a base part from viewpoints, such as compactization of the above glass plate package.

  In the above configuration, the glass plate receiving portion is a frame body in which frame members are assembled in a lattice shape, and the buffer body is disposed on the upper surface in a form along the upper surface of each frame member of the frame body. It is preferable to have a buffered substrate. 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 this way, since the buffer base material of the buffer body is arranged on the upper surface of the frame material of the frame body forming the skeleton of the glass plate receiving portion, and on the upper surface of the frame material, The load 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 lattice shape, if a buffer base material is placed at an appropriate position on the upper surface of the lattice frame material, an appropriate impact corresponding to the request for the glass plate laminate can be obtained. It is possible to ensure a relaxing action. 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.

  Furthermore, it is preferable that the said buffer body has a flexible sheet arrange | positioned so that the upper part of the said buffer base material may be covered. Here, the above-mentioned “flexible sheet” may perform a buffering action or may not perform a buffering action, but it is the 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 shape that is long in one direction, making the buffer base material extremely easy and fixing a plurality of buffer base pieces to the upper surface of each frame member. The work of attaching or sticking 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.

  In the above configuration, it is preferable that the buffer body is composed of a plurality of buffer base pieces, and the plurality of buffer base pieces are scattered over substantially the entire upper surface of the glass plate receiving portion.

  In the above configuration, it is preferable that the glass plate receiving portion is a frame body in which a frame material is assembled in a lattice shape, and the plurality of buffer base pieces are disposed on an upper surface of the frame material.

  In the above configuration, the width 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, and the dimension in the direction perpendicular to the width direction of the buffer base piece is The dimension in the width direction may be substantially the same.

  In the above configuration, the buffer base piece may be a columnar body.

  In the above configuration, the plurality of buffer base pieces may have two or more types of elasticity of each buffer base piece.

  In the above configuration, the plurality of buffer base pieces may be formed of a laminate of two or more layers in which each buffer base piece has two or more kinds of elasticity.

  In the above configuration, the frame body may be formed by arranging frame members vertically and horizontally, and the upper surface of the vertical frame member and the upper surface of the horizontal frame member may be located on the same plane.

  In the above configuration, the buffer body may include a flexible sheet arranged to cover the upper portions of the plurality of buffer base pieces.

  As described above, according to the present invention, the glass plate package is placed on the base portion in a state where the glass plate receiving portion can freely vibrate in the vertical direction, and is buffered on the upper portion of the glass plate receiving portion. Since it will be in the state by which the glass plate laminated body was mounted through the body, the lower part which supports the weight of the upper part of a glass plate package can ensure sufficient rigidity as a whole. In addition, since the glass plate receiving portion, which is a part of the lower portion, is light in weight and its inertia is reduced, when the vibration or impact is input to the lower portion, the glass plate receiving portion is It becomes easy to vibrate with respect to the high frequency component of the vibration transmitted from the base, and the low frequency component is difficult to transmit. For this reason, the glass plate receiving portion vibrates at a high frequency that is clearly different from the low frequency natural vibration of the upper portion. As a result, the high-frequency vibration input to the glass plate receiving part is easily absorbed by the vibration-proof structure made of the buffer, and hardly propagates to the glass plate laminated body above it, and the glass plate is broken or damaged. The probability of occurrence is greatly reduced.

  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 disposed. 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. More specifically, the glass plate receiving portion 4 is a frame body in which vertical frame members 4b and horizontal frame members 4b are arranged vertically and horizontally, and the upper surface of the vertical frame member 4b and the upper surface of the horizontal frame member 4b are the same surface. Located on the top. The base part 3 is longer in the vertical dimension, the horizontal dimension and the height dimension than the glass plate receiving part 4, and the weight of the glass plate receiving part 4 is that of the base part 3. It is said to be lighter than.

  The base part 3 and the glass plate receiving part 4 constitute the lower part of the glass plate package 1 when the buffer body 5 is used as a boundary. As shown in FIG. 3, the base portion 3 and the glass plate receiving portion 4 are separated into an edge-cut state and formed as separate frame bodies. In the state shown in FIG. 2, the glass plate receiving portion 4 is placed on the upper surface portion of the base portion 3 while being restricted from moving in the horizontal direction and allowed to move in the vertical direction. As a structure for this purpose, as shown in FIG. 3, a total of eight regulating members 3c are fixed to the upper surface of the base portion 3 so as to protrude upward, two on each side of the rectangle along a rectangular track. These restricting members 3c are configured to abut or substantially abut on the inner surface of the frame member 4b existing on the outermost periphery of the glass plate receiving portion 4. Thereby, as shown in FIG. 2, the glass plate receiving part 4 is mounted in the upper surface part of the base part 3 in the state which can vibrate freely to an up-down direction.

  FIG. 4 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. Moreover, the dimension of the direction orthogonal to the width direction of the buffer base piece 5b (direction orthogonal to the width direction on the horizontal plane) is substantially the same as the width direction dimension a. The number of buffer base pieces 5b is preferably 50 to 500, and more preferably 100 to 300.

  FIG. 5 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. 6 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 are 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. Even when the presser plate 7 is attached to the glass plate receiving part 4, the total weight is lighter than that of the base part 3.

  In such a state, the glass plate package 1 shown in FIG. 1 is obtained by erecting pillars at the four corners of the base 3. This glass plate packing plate 1 has a buffer body 5 as a boundary, and a base part 3 and a glass plate receiving part 4 which are constituent elements of the lower part thereof are separated into an edged state, and are attached to the base part 3 The movement of the glass plate receiving portion 4 with respect to the base portion 3 is restricted by the restriction member 3c, and the movement in the vertical direction is possible. Further, the regulating member 3c serves to guide the vertical movement of the glass plate receiving portion 4 with respect to the base portion 3, and the glass plate receiving portion 4 is completely separated from the base portion 6 and freely moves in the horizontal direction. It is allowed to move up to a possible position. And about the glass plate package 1 shown to the same figure, while covering the circumference | surroundings of the glass plate laminated body 6 with a stretch film or a film-like sheet | seat etc. and protecting from dust etc., a fastening member is used as needed. it can. 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. 7, 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 manufactured. 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. In addition, when the glass plate package 1 is stacked in a plurality of stages as described above, the plurality of base portions 3 are connected by the support columns 8 to form a single weight body, and the weight thereof is greatly increased. Since the glass plate receiving part 4 is separated from each base part 3, there is no change in weight.

  When the glass plate package 1 having the above configuration is divided into an upper part and a lower part with the buffer body 5 as a boundary, the glass plate receiving part 4 in the lower part is on the base part 3. Thus, the glass plate laminate 6 in the upper part is placed on the upper portion of the glass plate receiving portion 4 via the buffer body 5. And the upper side part is mainly comprised by the glass plate laminated body 6, and the natural vibration which this upper side part has is made into the low frequency if it is based on the general frequency of the field of glass plate packing. In such a state, the lower part supporting the weight of the upper part can secure sufficient rigidity as a whole due to the presence of the base part 3 and the glass plate receiving part 4, and the glass plate Since the receiving part 4 is separated from the base part 3, the weight is light and the inertia is reduced. Therefore, when vibration is input to the lower portion of the glass plate package 1, the glass plate receiving portion 4 is more likely to vibrate with respect to the high frequency component of vibration transmitted from the base portion 3, and the low frequency component is It becomes difficult to convey. Therefore, the glass plate receiving part 4 vibrates at a high frequency clearly different from the low frequency natural vibration of the upper part. As a result, the high-frequency vibration input to the glass plate receiving portion 4 is easily absorbed by the buffer 5 and hardly propagates to the glass plate laminate 6 above it, and the glass plate is broken or broken. Probability is greatly reduced. In this embodiment, since the weight of the glass plate receiving portion 4 (including the pressing member 7) is lighter than that of the base portion 3, the vibration absorbing effect by the buffer body 5 can be obtained more remarkably. Moreover, as shown in FIG. 7, when the glass plate package 1 is stacked in a plurality of stages, the plurality of base portions 3 are integrated to cause an increase in weight, whereas a plurality of glass plate receiving portions are provided. Since 4 can vibrate freely in the vertical direction independently without causing an increase in weight, the above-described advantages are very remarkable.

  FIG. 8 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.
