Description

[0001]
[Industrial applications]
The present invention relates to a package for a glass plate, for example, a package in which glass plates or the like for a liquid crystal display are arranged and stored in parallel in a substantially upright posture by a packaging holding material, and the periphery thereof is covered with an enclosure. About.
[0002]
[Prior art]
As is well known, a glass plate used for manufacturing a glass panel for various image display devices such as a liquid crystal display (LCD), a plasma display (PDP), an electroluminescence display (ELD), and a field emission display (FED), A glass plate used as a substrate for forming an electronic display function element or a thin film is usually transported from a glass maker or the like to a display maker or the like as a package in a state in which a plurality of sheets are stored and held as a group. is there.
[0003]
Further, for example, in the production of the above-described various image display devices and the like, a method in which a plurality of glass panels are produced from a single piece of base glass has been adopted, and accordingly, the glass panel is formed and processed by a glass maker. At present, raw glass sheets are being made larger.
[0004]
In detail, for example, the size of a glass panel of a liquid crystal display is generally about 10 to 20 inches diagonally, but in order to reduce the manufacturing cost and improve the production efficiency (throughput), Since the multi-system in which a large number of glass panels are formed on the base glass has been adopted, attempts have been made to make the base glass manufactured by a glass maker as large as possible.
[0005]
Specifically, in the early stage of commercial mass production, the size of the base glass was about 300 × 400 mm, but thereafter, with the increase in the number of glass panels taken, 370 × 470 mm size, 550 × 650 mm The size of the sheet glass has been increased to 680 × 680 mm or the like, and a raw glass sheet having a size of about 1000 × 1200 mm has now been manufactured.
[0006]
In addition, the above-listed glass plates and the glass plates according to them are, in fact, thin and easy to break, with the size increase, and the packing is strictly performed. There is a need. Therefore, various means have been devised for this type of glass plate packing means as described in Patent Documents 1 to 4 below.
[0007]
Specifically, for example, according to Patent Literature 1, four L-shaped holding pads (packing holding materials) are attached to four corners of a plurality of glass plates arranged in a substantially upright parallel arrangement, respectively, and a packing unit body is mounted. In addition, there is disclosed a package in which the single package unit is used as an internal container, and the entire periphery of the internal container is covered with a casing made of plastic cardboard. The package is configured to house and hold an internal container (packing unit; primary package in the document) with an air cushion interposed in the housing. In addition, the following Patent Document 2 discloses a package having a similar configuration.
[0008]
Further, for example, according to Patent Document 3 below, a plurality of glass plates are inserted and held in a pair of middle boxes in a state of being arranged substantially upright and side by side, and the entire periphery of the middle boxes is covered with a packaging material such as a polyethylene bag. A package is disclosed that is wrapped and that the upper and lower sides and side circumferences of the wrapped internal contents (in the same document, the middle box) are surrounded by an outer box with a cushioning material such as a urethane foam sheet or block interposed therebetween. ing. In addition, the following Patent Document 4 discloses a package having a similar configuration.
[0009]
On the other hand, when this kind of glass plate is transported over a long distance, such as when importing and exporting, the above-mentioned package is placed vertically and horizontally in a container having a bottom wall, a ceiling wall, and side walls. Are arranged in a plurality of rows and a plurality of rows are arranged vertically.

[Problems to be solved by the invention]
By the way, like the package disclosed in each of the above-mentioned documents, the upper and lower sides and the side periphery of the internal container are surrounded by a cushioning material such as an air cushion or urethane foam, and the surrounding body such as a housing or an outer box. Although the influence of the vibration acting on the glass plate at the time of transport can be mitigated when covered with, the following problem arises on one side.
[0012]
In other words, when the packages are stacked one on top of the other, the load of the upper package acts on the internal contents via the cushioning material of the lower package, and as a result, undesired deformation or deformation of the glass plate occurs. This causes a problem that cracks and the like occur.
[0013]
In particular, a situation in which the side walls of the casing and the outer box constituting the lower package are bulged outward and deformed or crushed and deformed due to the load of the upper package. When the occurrence occurs, the probability of occurrence of cracks or the like in the glass plate becomes extremely large.
[0014]
In view of the fact that the weight of one package is increasing to about 140 kg to 160 kg with the increase in the size of the glass plate as described above, such a problem becomes more remarkable.
[0015]
The present invention has been made in view of the above circumstances, and even when a load acts on the lower package from the upper side, such as when stacking the packages vertically, this load is It is a technical object to avoid as much as possible to directly act on the container, and to greatly reduce the probability of occurrence of undesired deformation or cracking of the glass plate.
[0016]
[Means for Solving the Problems]
The present invention made in order to solve the above technical problem has a packaging unit in which corners of a plurality of glass plates are covered with a packing holding material and each glass plate is held in a state of being arranged substantially upright in parallel. An internal container having one or more bodies, and a top plate for the internal container, a bottom surface, and a glass plate package including a surrounding body surrounding the four side surfaces,
The surrounding body includes two side plates that respectively cover at least two opposing side portions of the internal container, and an upper lid and a bottom lid that respectively cover an upper surface portion and a bottom surface portion of the internal container, and A restraining member is provided for pressing and supporting each side plate against each side surface of the internal container, and a space is provided between the entire upper surface portion of the internal container and the inner bottom surface of the upper lid. It is assumed that.
[0017]
According to such a configuration, a space is formed between the entire upper surface of the inner container and the inner bottom surface of the upper lid in a state in which each side plate is pressed against each side surface of the inner container by the restricting member and is restrained and supported. Therefore, even if a load is applied to the lower package from the upper side as in the case where the packages are stacked up and down, the presence of the space reduces the load to the internal container (package). Acting on the unit body) can be avoided, and the probability of occurrence of cracks or the like in the glass plate held in the packing unit body is drastically reduced. That is, since each side plate is pressed and restrained by the restraining member against each side portion of the internal container, even if a load from the upper stage acts on each side plate, each side plate is outwardly applied. The space is maintained at such a height that the load cannot be transmitted to the internal container. In other words, each side plate is restrained and supported so as not to be separated from each side portion of the internal container, and from a different viewpoint, each side plate is reinforced by the internal container, so that it is not easily deformed, Therefore, a situation in which the space is crushed and disappeared by the load from above is less likely to occur. As a result, the glass plate of the internal container is less likely to be unduly deformed or cracked due to the action of the load from above, and the glass plate is appropriately protected.
[0018]
In such a configuration, it is preferable that the space has a height dimension set to 5 mm to 20 mm.
[0019]
That is, if the height dimension of the space is less than 5 mm, even if the side plate is only slightly deformed by the load from the upper side, the space disappears and at the same time, the load on the internal container is reduced. This may cause a situation in which the glass plate acts, which may lead to undue deformation or cracking of the glass plate. On the other hand, when the height dimension of the space exceeds 20 mm, the package body is subjected to vibration during transportation or the like, so that a force acting on the internal container in the vertical direction is applied to the side portion of the internal container. When the internal support material overcomes the restraining support force by pressing against the side plate pressed against the side plate, the internal container moves up and down over an unduly long distance with respect to each side plate, and An object may alternately and strongly collide with the inner bottom surface of the upper lid and the inner bottom surface of the bottom lid, and in this case, the glass plate may be unduly deformed or cracked. In consideration of such circumstances, the height dimension of the above-described space is preferably 5 mm to 20 mm, but is 10 mm to 20 mm in consideration of safety regarding deformation of the side plate due to a load from above. Is more preferable.
[0020]
Further, in such a configuration, it is preferable that the height of the side plate is longer than the height of the internal container by the height of the space.
[0021]
That is, even if the difference between the height of the side plate and the height of the internal container does not correspond to the height of the space, the interposition member is provided between the inner bottom surface of the upper lid and the upper end of the side plate. A space similar to the above can be formed by interposing the above, but in such a case, the number of parts is increased and the packing operation (assembly operation) is complicated. Therefore, according to the above-described configuration in which the height dimension of the side plate is relatively increased by the required dimension, such a problem does not occur, which is advantageous in reducing the number of parts and simplifying the packing operation. It becomes.
[0022]
In the above configuration, it is preferable that the restraining member is formed of a film that wraps around a portion from the upper lid to the bottom lid. Here, the “film” may be colored or colorless, but is preferably a film whose inside can be seen through, such as a colorless transparent film, a colored transparent film, and a translucent film. As the film, a stretchable stretch film capable of reliably performing restraint support by a pressing force is suitable. For example, a heat-shrinkable synthetic resin film or the like may be used.
[0023]
By doing so, the thickness of the restraining member can be reduced, so that it is possible to contribute to downsizing and weight reduction of the package, and it is possible to restrain and support by applying a uniform pressing force over the whole. In addition, it is possible to reduce the cost and facilitate the packaging operation. In addition, the package can be made firmly overall by the film winding action, and the entire periphery of the internal storage can be sealed, contributing to the cleaning of the inside of the package. can do.
[0024]
Furthermore, in the above configuration, the side plates are provided with only two opposing plates, and the upper end and the lower end of the two side plates are respectively formed by the upper lid and the bottom lid formed separately from these. Covered, and the restraint member extends from the outer side surface of the side portion of the upper lid to the outer side surface of the two side plates and the outer side surface of the side portion of the bottom lid through the side surface portion of the internal container. It is preferred that it be wound over.
[0025]
With this configuration, since the top cover and the bottom cover are formed separately from the two side plates, if the restraining member is unwound, the two side plates, the top cover, and the bottom cover are all removed. These components can be separated and these components can be compactly stored when the used enclosure is returned and transported. Moreover, despite the fact that the number of side plates is two, the restraining member moves from the outer side surface of the side portion of the upper lid to the outer side surface of the two side plates and the side portion of the internal container through the side portion of the bottom lid. Since it is wound around the outer surface, sufficient strength can be ensured by the winding force and the like.
[0026]

[0031]
In the internal container 3, the packing units 2 are all arranged in the same direction. Then, when this internal container 3 is regarded as one aggregate composed of each packing unit 2, the internal container 3 as the aggregate includes an upper surface portion 3A, a bottom surface portion 3B, and a front side surface. There are provided a total of six surface portions including a portion 3C, a rear side portion 3D, a right side portion 3E, and a left side portion 3F.
[0032]
On the other hand, as shown in FIG. 3, the surrounding body 4 includes a top cover 9, a bottom cover 10, and a right side plate 11 that respectively cover the top surface 3 </ b> A, the bottom surface 3 </ b> B, the right side surface 3 </ b> E, and the left side surface 3 </ b> F of the internal container 3. And a left side plate 12 and a partition plate 13 interposed between the two packing units 2 adjacent to each other on the left and right. In this case, the right side plate 11, the left side plate 12, and the partition plate 13 have substantially the same height dimension and substantially the same width dimension (front-back dimension). The height of each of the plates 11, 12, and 13 is longer than the height of each of the packing units 2 (the internal contents 3) by 5 mm to 20 mm, preferably 10 mm to 20 mm. I have.
[0033]
The upper lid 9 and the bottom lid 10 have substantially the same size, and both the lids 9 and 10 are formed of paper cardboard or plastic cardboard, respectively, and have four side portions 9a and 10a. It has a rectangular shallow box shape. Adjacent side portions of the four side portions 9a, 10a of the lids 9, 10 may be separated from each other at the corner portions 9b, 10b, or may be separated without being connected. You may. That is, a structure in which the four lids 9 and 10 can be made flat by returning the four side portions 9a and 10a of the lids 9 and 10 that are bent during use to the non-folded state when not in use. It has been.
[0034]
The right side plate 11 and the left side plate 12 are the same article having compatibility, and may be made of wood, resin, light metal, or other materials. As shown, reinforcing woods 11b and 12b are fixed to the outer surfaces of the veneer plywood 11a and 12a in a framed state, and buffering plates 11c and 12c made of paper or plastic cardboard are fixed to the inner surfaces thereof. Is used. Similarly, the partition plate 13 is not particularly limited in its material, but when it is formed of a wood-based plate material, for example, paper or plastic cardboard is provided on both sides of the veneer plywood 13a as shown in the figure. What fixed the buffer plates 13b and 13c is used.
[0035]
The distance between the sides (9a, 9a) and (10a, 10a) on the front and rear sides of the upper lid 9 and the bottom lid 10 is set to be substantially the same as the longitudinal dimension of each of the plates 11, 12, and 13 described above. Have been. In other words, the plates 11, 12, and 13 can be inserted and removed between the side portions (9a, 9a) and (10a, 10a) on the front and rear sides of the lids 9, 10. , Dimensions have been set.
[0036]
Further, the surrounding body 4 includes a pallet 14 (base) having a rectangular shape having substantially the same area as the lids 9 and 10 in plan view (area when viewed from above) and a stretch film 15 as a transparent film. Have. The bottom cover 10 is placed on the upper surface of the pallet 14, and a plurality of through holes 14 b are formed in each of four side walls 14 a of the pallet 14.
[0037]
The stretch film 15 is made of polyethylene and has an appropriate elasticity, and wraps and wraps a required portion of the enclosure 4 including the open side surfaces 3C and 3D of the internal container 3 at the same time. A pressing force for pressing each of the side plates 11 and 12 against the entire side surfaces 3E and 3F of the internal container 3 is applied by the wrapping action of the wrap packaging, and the side plates 11 and 12 are pressed to the respective side portions 3E. , 3F.
[0038]
The assembling procedure (packing procedure) of the package 1 having the above-described components and the configuration after assembly will be described below.
[0039]
First, with the bottom cover 10 placed on the upper surface of the pallet 14, the lower end of the right side plate 11 is made to enter the bottom cover 10, and the lower end of the right side plate 11 is attached to the right side of the bottom cover 10. The bottom cover is brought into contact with the inner surface of the portion 10a, and the two packing units 2 are placed in such a manner that the two packing units 2 come into contact with each other back and forth, and the right side portions of both come into contact with the buffer plate 11c of the right side plate 11. Place in 10. In this case, in a state where the two packages 1 are in front and rear contact, the total length in the front and rear direction is substantially the same as the mutual separation dimension of the side portions 10a and 10a on both the front and rear sides of the bottom cover 10. The dimensions are set so that
[0040]
Thereafter, the lower end of the partition plate 13 is made to enter the bottom cover 10, and the buffer plate 13 b on the right side of the partition plate 13 is brought into contact with the left side portion of the two packing unit bodies 2. The remaining two packing units 2 are placed in the bottom lid 10 such that the two abut against each other and the right side portions of the two abut against the buffer plate 13c on the left side of the partition plate 13. . Next, the lower end of the left side plate 12 is inserted between the inner side surface of the left side portion 10a of the bottom cover 10 and the remaining two packing units 2, and the buffer plate 12c of the left side plate 12 is inserted. Then, the remaining two packing units 2 are brought into contact with the left side surfaces. At this point, the left and right side plates 11 and 12, the partition plate 13, and the glass plate G of each packing unit 2 are all parallel.
[0041]
Under such a state, the upper end of the internal container 3 composed of four packing units 2, the upper end of the partition plate 13 interposed at the center in the left-right direction of the internal container 3, The upper lid 9 is put over the upper end portions of the left and right side plates 11 and 12 that cover the left and right outer surface portions of the container 3. In this case, as shown in FIGS. 4 and 5, the height dimensions of the left and right side plates 11, 12 and the partition plate 13 are longer than the height dimensions of each packing unit 2. Under a state where the inner bottom surface of the upper lid 9 is in contact with the upper ends of the plates 11, 12, and 13, the height t is 5 mm between the entire upper surface portion of each packing unit 2 and the inner bottom surface of the upper lid 9. A space 16 of 20 mm, preferably 10 mm-20 mm (15 mm in this embodiment) is formed.
[0042]
Thereafter, as shown in FIG. 1, the outer wrapping band 18 passing through the through hole 14 b of the side wall portion 14 a of the pallet 14 is wound from the bottom cover 10 to the upper surface of the upper cover 9, so that the upper At the same time as the side plates 11, 12 and the bottom cover 10 are bound together. After the binding, the entire periphery of the region from the outer surface of each side 9a of the top cover 9 to the outer surface of each side 10a of the bottom cover 10, that is, the outer surface of each side 9a of the top cover 9 Outer surfaces of left and right side plates 11 and 12, front and rear outer end surfaces of partition plate 13, front and rear side portions 3 </ b> C and 3 </ b> D of internal container 3, and outer surfaces of side portions 10 a of bottom lid 10. Is wound around with the stretch film 15. In this case, it is preferable to wrap the stretch film 15 up to the outer surface of each side wall portion 14a of the pallet 14. Instead of the above procedure, winding by the outer wrapping band 18 may be performed after wrapping by the stretch film 15.
[0043]
As a result of executing the above procedure, the package 1 shown in FIG. 1 is obtained. According to the package 1, the right side 3E and the left side 3F of the four side parts 3C to 3F of the internal container 3 composed of the four packing units 2 are separated by the right and left side plates 11, 12. Although it is covered, the front side 3C corresponding to the front and the rear side 3D corresponding to the back are in an open state and are covered only by the transparent stretch film 15, so that the packing unit 2 The lot label 8 attached to the front can be visually recognized. Therefore, the information such as the type of the glass plate G stored in the packing unit 2 from the outside can be transmitted to the lot label 8 without removing the packing unit 2 from the surrounding body 4 each time or removing the side plate. Thus, the inside of the package 1 can be easily checked at the time of shipment from a glass maker or the like. In addition, since the bar code attached to the lot label 8 or the like can be read by a bar code reader from the outside, the glass plate G inside the package 1 can be read, for example, at the time of receiving at a display manufacturer. There is also obtained an advantage that various kinds of information regarding can be obtained efficiently and accurately.
[0044]
Further, since neither side surface plate is provided in the portion corresponding to the front side surface and the rear side surface of the enclosure 4, as can be understood from FIG. 5, the thickness corresponds to the plate thickness of the two side surface plates. The front and rear dimensions of the top lid 9 and the bottom lid 10 are shortened by that much, and thus the front and rear dimensions of the package 1 are short. Thereby, the package 1 is made compact. For example, as shown in FIG. 6, the plurality of packages 1 are placed in a container so that the longitudinal direction of the container 17 and the front-rear direction of the package 1 coincide. At the time of loading into the inside of the package 17, the number of packages 1 that can be loaded can be increased, and transportation costs can be reduced.
[0045]
In addition, the packing body 1 is configured such that the left and right side plates 11 and 12 and the partition plate 13 are higher than the packing unit body 2, so that the entire upper surface portion of each packing unit body 2 and the inner bottom surface of the upper lid 9 are formed. Since the space 16 is provided between them, when the packages 1 are vertically stacked, the load of the upper package 1 is mainly applied to the side plates 11 and 12 and the partition plate 13 of the lower package 1. This prevents a situation in which an unreasonable load acts on the packing unit 2. That is, since the side plates 11, 12 and the partition plate 13 in this embodiment have high rigidity, the strength against a vertical load is large, and more specifically, the rigidity is higher than the corrugated cardboard forming the upper lid 9 and the bottom lid 10. Therefore, problems such as bending and deformation of the side plates 11, 12 and the partition plate 13 are less likely to occur, and a situation in which a vertical load acts on the packing unit 2 from the upper stage can be avoided.
[0046]
In this case, even if the side plates 11 and 12 and the partition plate 13 have the same rigidity or strength as that of corrugated cardboard, the partition plate 13 is sandwiched between the unit packages 1 from both sides, and the side plates 11 and 12 are stretched. Because the film 15 is pressed against the entire side surface of the unit package 1 by the winding action of the film 15 and is restrained and supported, these plates 11, 12, and 13 may be deformed or crushed by a vertical load from the upper stage. Problems are less likely to occur. Therefore, even in this case, the problem that the vertical load acts on the packing unit 2 is avoided as much as possible, and the glass plate G is unduly deformed or broken due to the action of the vertical load on the packing unit 2. Etc. occurrence probability is drastically reduced.
[0047]
Focusing on the effect of the vertical load as described above, the height t of the space 16 is preferably 5 mm or more, more preferably 10 mm or more. On the other hand, when the package 1 is vibrated during transportation or the like, the package unit 2 moves up and down relative to the side plates 11 and 12, and the inner bottom surface of the top cover 9 and the bottom cover The glass plate G collides with the inner bottom surface of the glass plate 10, and in this case, there is a possibility that the glass plate G may be unduly deformed or cracked. In consideration of this, the height t of the space 16 is preferably equal to or less than 20 mm.
[0048]
Further, when the package 1 has been used, the pallet 14, the top cover 9, the bottom cover 10, the left and right side plates 11, 12 and the partition plate 13 are separated from each other, and these are aligned in a predetermined state. If they are tied together, they can be stored more compactly. Furthermore, if the side parts 9a, 10a of the upper lid 9 and the bottom lid 10 are separated and developed at the corners 9b, 10b, they can be stored more compactly. .
[0049]
In this embodiment, the four packing units 2 are used as the internal contents 3. However, other packing units 2 such as one, two, six, eight, or nine are used. The internal container 3 may be used. In this embodiment, the partition plate 13 is interposed between the packing units 2 adjacent to each other on the left and right. However, even if the use of the partition plate 13 is abolished, the function as the package 1 is sufficiently exhibited. can do.
[0050]
Further, in this embodiment, the side wall of the enclosure 4 is constituted by the right side plate 11 and the left side plate 12, but the side wall of the enclosure 4 A front side plate and / or a rear side plate covering the front side portion 3C and / or the rear side portion 3D may be separately provided. That is, you may make it cover three or four side parts of the internal container 3 with three or four side plates, respectively.
[0051]
Further, in this embodiment, the stretch film 15 is used as a restraining member for wrapping around a portion from each side 9a of the top cover 9 to each side 10a of the bottom cover 10, but for example, a transparent resin It may be a heat-shrinkable film or another transparent film. In addition, the constraining member may be a film that is not transparent and has a light-shielding property, and may be a resin cloth instead of a film.

Furthermore, in this embodiment, four L-shaped ones into which the four corners of the glass plate G are inserted and held are used as packing holding materials (holding pads) which are components of the packing unit. The number of the holding members is not particularly limited, and may be, for example, two, and the shape is not particularly limited, and may be, for example, a box shape or a similar shape.
[0053]
Further, in this embodiment, a space 16 where nothing exists is formed between the entire upper surface portion 3A of the internal container 3 and the inner bottom surface of the upper lid 9. For example, when a cushioning material is interposed in this space 16. The height dimension of the space 16 from which the thickness in the height direction of the cushioning material is subtracted is 5 mm to 20 mm (preferably 10 mm to 20 mm).

【The invention's effect】
As described above, according to the package according to the present invention, the upper surface portion and the lower surface portion of the internal container consisting of one or a plurality of packing units in which a plurality of glass plates are stored and held in a substantially upright side-by-side configuration. A top cover and a bottom cover, and a restraining member for pressing and supporting at least two side plates against two opposing side portions of the internal container, and constraining and supporting the entire upper surface portion of the internal container and the inner bottom surface of the upper lid. Even if a load is applied to the lower package from the upper side as in the case where the packages are stacked up and down as in the case where the packages are stacked up and down, due to the presence of the space, the load is reduced to the internal container ( Acting on the packaging unit), and the probability of occurrence of cracks or the like in the glass plate held in the packaging unit is drastically reduced.
[0055]
In this case, if the height of the space is set to 5 mm to 20 mm (preferably 10 mm to 20 mm), the space disappears when the side plate is only slightly deformed by the load from above. At the same time as the trouble is avoided, the inner container moves up and down over an unduly long distance with respect to each side plate when the package is in a state of being subjected to vibration, such as during transportation, and the top cover The occurrence of cracks in the glass plate or the like due to alternate strong collision with the inner bottom surface of the bottom lid and the inner bottom surface of the bottom lid is also suppressed.
[0056]
In addition, if the height of the side plate is longer than the height of the internal container by the height of the space, the difference between the heights of the two components can be provided only by providing a difference in height. A matching space is formed, and the packing operation can be simplified without unnecessarily increasing the number of parts.
[0057]
Furthermore, if the restraining member is formed of a film that wraps around the portion from the top lid to the bottom lid, the restraining member can be reduced in thickness and weight, and can contribute to the compactness of the package. A uniform pressing force can be exerted over the entire body to restrain and support it, and it is also possible to reduce the cost and facilitate the packing operation. In addition, by the action of winding the film, the package can be made to be entirely solid, and the entire periphery of the internal container can be sealed, which contributes to the cleaning of the inside of the package. be able to.
[0058]
In addition, the above-mentioned side plates are provided only with two opposing ones, and the upper lid and the bottom lid are separate from each other. By tightening the restraining member over the outer surface of the side of the bottom lid through the part, it is possible to compactly store each of these components when returning and transporting the used enclosure In addition, despite the two side plates, sufficient strength can be ensured by the tightening force of the restraining member and the like.
