Description

The present invention relates to a glass roll package and a method for producing the same.

As is well known, in recent years, there has been a demand for further thinning of various glass plates including glass substrates for flat panel displays such as liquid crystal displays, plasma displays, organic EL displays, and field emission displays. .. Therefore, in response to the request, the development of a so-called glass film, which has been thinned to a film shape, has been promoted, and for example, a glass film having a thickness of 200 μm or less has been developed.

Further, as a packaging form of the glass film, a glass roll in which the glass film is wound around a winding core in a roll shape is being adopted. Such a packaging form focuses on the flexibility of the glass film, and has various advantages such as space saving, and thus is attracting attention as a packaging form suitable for the glass film.

By the way, since this kind of glass product (glass film) is required to have high surface quality (for example, cleanliness) depending on the application, when the above-mentioned glass film is packed and transported in the form of a glass roll, it is carried. It is necessary to prevent situations that cause contamination of the glass roll, such as adhesion of foreign matter and corrosion.

Here, for example, in Patent Document 1, as a packaging container for glass rolls, a box body in which a storage chamber for storing the glass roll is formed is formed, and a lid member attached to an opening of the box body to seal the storage chamber. A glass roll packaging container is disclosed, which comprises a humidity adjusting unit for adjusting the humidity of the storage chamber, and the storage chamber is adjusted to a dry state by the humidity adjusting unit after the glass roll is stored. Has been done.

Japanese Unexamined Patent Publication No. 2014-80203

As described above, in the case of the packaging container described in Patent Document 1, since the storage chamber of the glass roll provided inside the box body can be sealed, foreign matter that invades the inside of the box body together with the outside air and eventually the outside air can enter the box body. It seems that adhesion to the glass film can be effectively prevented. However, if the inside of the box body is to be sealed as described in Patent Document 1, the structure of the packaging container including the box body becomes complicated. This is not preferable because it may lead to an increase in the manufacturing cost of the packaging container.

In view of the above circumstances, it is a technical problem to be solved by the present invention to produce a glass roll package having a simple structure and capable of preventing contamination of the glass roll.

The solution to the above problems is achieved by the glass roll package according to the present invention. That is, this package supports a glass roll formed by winding a glass film around the winding core in a roll shape with both sides in the axial direction of the winding core exposed, and both sides in the axial direction of the winding core. A glass roll packaging body having a pair of support portions and including a box body for accommodating a glass roll supported by the pair of support portions, in a state where the entire glass roll is covered with a bag body. , The glass roll is characterized by being supported by a pair of supports.

As described above, in the packaging body according to the present invention, the entire glass roll is covered with the bag body in the state of being housed in the box body. The glass film can be protected from the outside air by covering the entire glass film wound in a shape with a bag body. This makes it possible to prevent a situation in which the outside air is exposed to the glass film more easily than in the past, and eventually a situation in which foreign matter adheres to the glass film. Of course, since it is only necessary to prepare the bag body, the glass film can be protected from the outside air at a lower cost than, for example, processing the box body into a closed structure.

Further, in the packaging body according to the present invention, the glass roll is supported by a pair of support portions while the entire glass roll is covered with the bag body as described above. Therefore, for example, the following procedure is performed. By stepping on, the glass roll can be easily loaded inside the box and packed. That is, the entire glass roll is housed inside the bag body which has been installed inside the box body in advance, and at the same time, both sides of the winding core in the axial direction are placed on the pair of support parts. Then, the bag body is closed. As a result, the glass roll is housed in the box body, and the entire glass roll is covered with the bag body and supported by the pair of support portions. From the above, according to the present invention, it is possible to load and pack the glass roll inside the box body with a relatively small number of man-hours. Further, when taking out the glass roll, it is sufficient to open the box body and take out the glass roll together with the winding core, so that the glass roll can be easily taken out from the box body.

Further, in the glass roll package according to the present invention, the bag body may have an opening at one place.

In this way, if a bag body having an opening at one place is provided, it is only necessary to close one place after accommodating the entire glass roll including the winding core inside the bag body through the opening. , The entire glass roll can be easily covered with a bag.

Further, in the glass roll package according to the present invention, flanges facing the entire width direction end surface of the glass film via a predetermined gap are attached to both sides of the winding core in the axial direction. You may. The width direction referred to here means the direction along the winding center of the glass film.

By providing flanges on both sides of the winding core in the axial direction in this way, for example, when the entire glass roll moves in the width direction, the situation where the end face in the width direction of the glass film comes into contact with the box body can be reliably avoided. Damage to the end face can be reliably prevented.

Further, when the flange has the above configuration, in the glass roll package according to the present invention, the bag may cover both the entire glass roll and the flange.

By covering not only the glass roll consisting of the winding core and the glass film but also the flange attached to the winding core with the bag body, the flange regulates the movement of the bag body to the glass roll, and the outer peripheral surface of the glass roll. A certain space can be formed between the bag and the bag. This makes it possible to reliably prevent contamination and breakage of the glass film due to unnecessary contact between the bag body and the glass roll.

Further, in the glass roll package according to the present invention, the flange and the support portion are prevented from falling from one of the support portions of the glass roll due to the movement in the width direction due to the contact between the flange and the support portion. A gap may be set with.

By setting the gap between the flange and the support portion in this way, even if the glass roll shifts in the width direction during transportation, the flange regulates the movement of the glass roll in the width direction at a predetermined position. It is possible to reliably prevent a situation in which one side portion in the axial direction falls from one support portion.

Further, in the glass roll package according to the present invention, the support portion is divided into upper and lower parts, and a lower support portion that supports the lower side of the outer peripheral surface of the winding core and an upper support portion that supports the upper side of the outer peripheral surface of the winding core. The upper support portion may be rotatably supported around a predetermined rotation axis so as to be movable between the support position of the winding core and the retracted position away from the support position.

By adopting the structure in which the support portion is divided into upper and lower parts in this way, the winding core of the glass roll can be easily placed on the support portion or separated from the support portion. Further, at this time, since the divided upper support portion is rotatably supported around a predetermined rotation axis, the upper support portion can be easily moved between the support position and the retracted position of the winding core. Can be. As a result, when loading the glass roll, the upper support portion is first retracted from the space above the lower support portion (that is, the support position of the winding core), and after the glass roll is placed, the upper support portion is rotated in a predetermined manner. Rotate it around the axis to bring it into contact with the upper side of the outer peripheral surface of the winding core. After that, by fixing the upper support portion to the lower support portion, the winding core can be easily sandwiched and fixed between the upper and lower support portions. Also, when taking out the glass roll, the glass roll can be lifted up and taken out from the inside of the box simply by first rotating the upper support part around the rotation axis and retracting it from the space above the lower support part. it can. From the above, according to the support portion having the above configuration, it is possible to efficiently load or take out the glass roll.

Further, in the glass roll package according to the present invention, the box body may have a frame body and a plurality of plate-shaped bodies that have an outer wall of the box body and are detachably attached to the frame body.

In this way, by adopting a structure in which the plate-shaped body forming the outer wall of the box body is detachably attached to the frame body of the box body, the accessibility to the glass roll in the state of being housed in the box body is enhanced. Can be done. That is, by removing the plate-shaped body, the winding core in a state of being supported by the support portion provided on the frame body can be accessed from the side of the box body, so that the winding core can be easily lifted and the glass roll. Can be taken out. Of course, when loading the glass roll, the glass roll can be easily placed inside the box by placing the winding core of the glass roll on the support portion with the plate-shaped body located outside the support portion removed. Can be accommodated in.

Further, when the box body has a frame body and a plurality of plate-shaped bodies, in the glass roll package body according to the present invention, a pair of support portions are formed by a part of the frame body, and the frame body is formed. An insertion portion into which a plate-shaped body can be inserted may be provided outside the support portion.

By forming a pair of support portions with a part of the frame body in this way, the box body can be further simplified and contributes to compactness. Further, by providing an insertion portion into which the plate-shaped body can be inserted outside the support portion of the frame body, the plate-shaped body can be easily attached to and detached from the frame body. As a result, workability related to loading or unloading of the glass roll can be further improved.

Further, the solution of the above problems is also achieved by the method for producing a glass roll package according to the present invention. That is, this manufacturing method includes a step of winding a glass film around the winding core in a roll shape to produce a glass roll with both sides of the winding core exposed in the axial direction, and both sides of the winding core in the axial direction. At the same time as the process of installing the bag body inside the box body having a pair of support parts for supporting the glass roll and the entire glass roll including both axially both sides of the winding core inside the bag body, the shaft of the winding core. It is characterized by having a step of placing both side portions on a pair of support portions and a step of closing the bag body.

As described above, according to the method for producing a package according to the present invention, as in the case of the package described above, the entire glass film wound into a roll is formed into the bag by simply accommodating the glass roll inside the bag. The glass film can be protected from the outside air in a covered state. This makes it possible to prevent a situation in which the outside air is exposed to the glass film more easily than in the past, and eventually a situation in which foreign matter adheres. Of course, since it is only necessary to prepare the bag body, the glass film can be protected from the outside air at a lower cost than, for example, processing the box body into a closed structure. In addition, the entire glass roll is housed inside the bag body that has been installed inside the box body in advance, and at the same time, both sides of the winding core in the axial direction are placed on the pair of support parts, and then the bag body is placed. By closing the opening, the glass roll is housed in the box body, and the entire glass roll is covered with the bag body and supported by a pair of support portions. Therefore, according to the present invention, it is possible to load and pack the glass roll inside the box body with a relatively small number of man-hours. Further, when taking out the glass roll, it is sufficient to open the box body and take out the glass roll together with the winding core, so that the glass roll can be easily taken out from the box body.

As described above, according to the present invention, it is possible to produce a glass roll package capable of preventing contamination of the glass roll while having a simple structure.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 10.

FIG. 1 is an exploded perspective view of the glass roll packing body 10 according to the present embodiment, FIG. 2 is a plan view of the same glass roll packing body 10, and FIG. 3 is a side view of the same glass roll packing body 10. Is. As shown in these figures, the glass roll packing body 10 has a glass roll 11 and a pair of support portions 12 and 12 for supporting the glass roll 11, and a box body 13 for accommodating the glass roll 11 and glass. A bag body 14 that covers the entire roll 11 is provided. Further, in the present embodiment, the glass roll packing body 10 further includes a pair of flanges 15 and 15 attached to the glass roll 11.

Here, as shown in FIG. 4, the glass roll 11 to be packed is formed by winding a long glass film G around the winding core 16, and in the present embodiment, it is formed on the outer peripheral surface of the winding core 16. , The glass film G and the cushioning sheet 17 are in a state of being wound up in a roll shape in a state of being overlapped.

As shown in FIG. 4, for example, the winding core 16 has a hollow cylindrical shape having a hole portion 16a. Further, the axially both side portions 16b and 16b of the winding core 16 are exposed portions in a state where the glass film G is wound in a roll shape, and from a different point of view, the width direction of the glass film G wound in a roll shape. It corresponds to a portion of the glass film G protruding in the width direction from both end faces. The winding core 16 is not limited to the hollow cylindrical shape according to the illustrated example, and may be, for example, a solid cylindrical shape.

The material of the winding core 16 is arbitrary as long as there is no problem in terms of strength, and for example, metals such as aluminum alloy, stainless steel, manganese steel, and carbon steel, phenol resin, urea resin, melamine resin, unsaturated polyester resin, and epoxy. Thermocurable resins such as resins, polyurethanes and diallyl terephthalate resins, thermoplastic resins such as polyethylene, polypropylene, polystyrene, AS resins, ABS resins, methacrylic resins and vinyl chloride, or these thermocurable resins and thermoplastic resins with glass Reinforced plastic, paper, or the like, which is a mixture of reinforcing materials such as fibers and carbon fibers, can be applied as the material of the winding core 16.

The glass film G is formed by, for example, an overflow down draw method, and the thickness dimension is set in the range of 1 μm to 200 μm (preferably 10 μm to 100 μm). The reason for setting such a thickness is that if the thickness is within the numerical range, it is possible to impart appropriate flexibility and strength to the glass film G, and there is no problem during winding. Is.

The width direction dimension of the glass film G is set to, for example, 100 mm or more, preferably 300 mm or more, more preferably 500 mm or more, and further preferably 1000 mm or more. Since the glass film G is used in a wide range of devices from a small screen display such as a small mobile phone to a large screen display such as a large television receiver, the width direction dimension of the glass film G is determined. Ultimately, it is preferably selected as appropriate according to the size of the substrate of the device to be used.

As the glass composition of the glass film G, various glass compositions such as silica glass and silicate glass such as borosilicate glass can be used, but it is preferable to use non-alkali glass depending on the application. This is because when the glass film G contains an alkaline component, a phenomenon called soda blowing occurs and a part of the glass film G becomes structurally rough, and when the glass film G is curved, it deteriorates over time. This is because there is a possibility that damage may occur from the structurally roughened portion. Further, if the glass film G contains an alkaline component, when the glass film G is used for a glass substrate application, the thin film characteristics formed on the surface may be impaired. The non-alkali glass referred to here is a glass that does not substantially contain an alkaline component, and specifically, the alkali metal oxide is 3000 ppm or less (preferably 500 ppm or less, more preferably 300 ppm). The following).

From the viewpoint of protecting the glass film G, the cushioning sheet 17 is wound around the winding core 16 in a state of being overlapped with the glass film G, and when the winding is completed (states shown in FIGS. 1 and 4), the glass is glass. It is interposed between the films G. At this time, the cushioning sheet 17 is arranged so as to cover the entire front and back surfaces (first and second main surfaces) of the glass film G, thereby protecting the entire front and back surfaces of the glass film G. ing. From the viewpoint of protecting the glass film G, the cushioning sheet 17 is positioned on the innermost diameter side and the outermost diameter side of the roll portion 11a in a state where the winding of the glass film G with respect to the winding core 16 is completed. Is preferable. Further, from the same viewpoint, it is preferable that the cushioning sheet 17 protrudes from both end faces in the width direction of the glass film G. Of course, both end faces in the width direction of the cushioning sheet 17 and both end faces in the width direction of the glass film G may be aligned at the same width direction position, or the glass film G bites from both end faces in the width direction of the cushion sheet 17. You may put it out.

The thickness dimension of the cushioning sheet 17 is preferably 10 μm or more from the viewpoint of obtaining a sufficient cushioning effect, and 2000 μm or less from the viewpoint of preventing unreasonable expansion of the roll portion 11a of the glass roll 11. preferable.

In principle, the material of the cushioning sheet 17 is arbitrary, and for example, interleaving paper or non-woven fabric can be applied. In addition to the materials exemplified above, for example, ionomer, polyethylene, polyethylene terephthalate, polypropylene, polyvinyl chloride, polyvinylidene chloride, polyvinyl alcohol, polyester, polycarbonate, polystyrene, polyacrylonitrile, ethylene-vinyl acetate copolymer, ethylene. A resin sheet formed of a resin such as a vinyl alcohol copolymer, an ethylene-methacrylic acid copolymer, nylon (polyamide), polyimide, or cellophane can be applied. From the viewpoint of ensuring both cushioning performance and strength at the same time, it is preferable to use a foamed resin sheet formed of a foamed resin such as polyethylene as the cushioning sheet 17. Further, from the viewpoint of improving the slipperiness with the glass film G, it is preferable to use as the cushioning sheet 17 a resin sheet formed by dispersing silica or the like in the above-mentioned resin. In this case, the slipperiness of the resin sheet can absorb the deviation that occurs between the glass film G and the cushioning sheet 17.

Further, in the present embodiment, a pair of flanges 15 and 15 are attached to the winding core 16 of the glass roll 11. These flanges 15 and 15 are attached to both side portions 16b and 16b in the axial direction of the winding core 16 and face the end face in the width direction of the glass film G and the entire area thereof (see FIG. 2). That is, the outer diameter of the flange 15 is larger than the outer diameter of the roll portion 11a formed by winding the glass film G around the winding core 16. Further, in the present embodiment, each flange 15 faces the end face of the glass film G in the width direction through a predetermined gap in the width direction.

Each flange 15 may be, for example, a disk-shaped integrated product, but in the present embodiment, as shown in FIG. 4, each flange 15 is composed of a first dividing plate 15a and a second dividing plate 15b, both of which form a semi-disk shape. Will be done. In this case, with the axial side portions 16b and 16b of the winding core 16 sandwiched between the first dividing plates 15a and 15a of each flange 15 and the second dividing plates 15b and 15b, the first dividing plate 15a and the first By connecting the two-split plate 15b by, for example, bolting, a pair of flanges 15 and 15 having a disk shape as a whole are fixed to the outer periphery of the winding core 16.

In the present embodiment, for the purpose of reducing the processing cost, the outer peripheral surface of the winding core 16 has a constant outer diameter dimension, but for the purpose of accurately positioning the flange 15 with respect to the winding core 16 in the axial direction. Therefore, for example, although not shown, a step may be provided on the outer periphery of the winding core 16 so that the flange 15 is brought into contact with the step in the axial direction.

The box body 13 has a substantially rectangular parallelepiped shape as a whole, and in the present embodiment, the frame body 18 and a plurality of plate-shaped bodies 19 which form an outer wall of the box body 13 and are detachably attached to the frame body 18. (See FIG. 1). In this case, the glass roll 11 and the bag body 14 are housed inside the box body 13. Further, the frame body 18 is provided with a pair of support portions 12 and 12, and the pair of support portions 12 and 12 support the glass roll 11 housed inside the box body 13.

More specifically, the pair of support portions 12, 12 support the axially both side portions 16b, 16b of the winding core 16, as shown in FIG. At this time, the axially both side portions 16b and 16b of the winding core 16 are supported by a pair of support portions 12 and 12 via the bag body 14, as shown in FIG.

Here, as shown in FIG. 3, each support portion 12 is divided into upper and lower parts, and a lower support portion 20 that supports the lower side of the outer peripheral surface of each axial side portion 16b, and each axial side. It has an upper support portion 21 that supports the upper side of the outer peripheral surface of the portion 16b. Further, the upper support portion 21 is rotatably supported around a predetermined rotation shaft 22 arranged on the frame body 18, whereby the upper support portion 21 is positioned above the lower support portion 20. (That is, the support position of the winding core 16 shown in FIG. 3) and the retracted position (see FIG. 1) away from the support position are movable.

In the present embodiment, the lower support portion 20 is formed by deforming a part of the frame body 18, and the support surfaces 20a of the lower support portion 20 are a pair of slopes that approach each other as they go downward. It is formed (see FIG. 3). Further, in the present embodiment, the upper support portion 21 has a substantially semi-annular curved portion that is separate from the frame body 18, and the support surface 21a of the upper support portion 21 is a semi-annular curved portion. It is formed on the inner peripheral surface of. In this case, in a state where the upper support portion 21 is rotated around the rotation shaft 22 and moved above the lower support portion 20, the axial side portion 16b of the winding core 16 to be supported is moved from the vertical direction. It can be pinched (see Fig. 3).

When a pair of flanges 15 and 15 are attached to the winding core 16 of the glass roll 11, the glass roll 11 moves in the width direction due to contact between the flange 15 and the support portion 12 (here, the lower support portion 20). The gap g1 between each flange 15 and the frame 18 is set to a predetermined size or less so as to prevent the flange 12 from falling from the support portion 12 (see FIGS. 2 and 5). In other words, even if the glass roll 11 moves in the width direction by the amount of the gap g1, the gap g1 is predetermined so that the axial side portion 16b of the winding core 16 remains on the support portion 12 on the side opposite to the moving direction. Is set to the size of. The gap g2 (see FIG. 2) between the flange 15 on the opposite side and the frame 18 is also set to a predetermined size or less for the same reason. Since these gaps g1 and g2 function as play when the glass roll 11 is housed inside the box body 13, it is preferable to set each gap g1 and g2 to a certain size from the viewpoint of loadability. ..

Further, in the present embodiment, an insertion portion 23 into which the plate-shaped body 19 can be inserted downward is provided outside the support portion 12 of the frame body 18 (see FIGS. 1 to 3). The insertion portion 23 has a groove shape, for example, and is adapted to fit the bottom side 19a and the pair of side sides 19b, 19b of the inserted plate-like body 19. Of course, the insertion direction of the plate-shaped body 19 is not limited to the downward direction. For example, although not shown, the insertion portion 23 may be configured so that the plate-shaped body 19 in the vertical posture is slid in the horizontal direction so as to be set at a position forming the outer wall of the box body 18.

In the present embodiment, the bag body 14 has an opening 24 at one place, and as shown in FIG. 1, the bag body 14 can be arranged so that the opening 24 faces upward when it is housed inside the box body 13. It is said that. Further, the opening 24 has a size capable of inserting a glass roll 11 in a state where the pair of flanges 15 and 15 are attached to both side portions 16b and 16b in the axial direction of the winding core 16. At this time, as shown in FIG. 1, the size and shape of the opening 24 are large enough to allow the glass roll 11 to be inserted in a posture in which the width direction of the glass roll 11 (longitudinal direction of the winding core 16) is substantially horizontal. It should be set.

As shown in FIGS. 2 and 3, the bag body 14 having the above configuration accommodates the entire glass roll 11 including the axially both side portions 16b and 16b of the winding core 16. In the present embodiment, the entire glass roll 11 including the pair of flanges 15 and 15 is housed inside the bag body 14. In this case, the opening 24 (see FIG. 1) of the bag body 14 is in a closed state above the glass roll 11, in other words, the opening 24 is closed above the glass roll 11. The portion 25 is formed. Further, in this case, the flange 15 may come into contact with the bag body 14, or by positively contacting the bag body 14, the bag body 14 is partially stretched, and the bag body 14 and the roll portion 11a of the glass roll 11 are partially stretched. The distance from the outer peripheral surface of the glass is secured (see FIG. 5).

In the present embodiment, the box body 13 including all of the glass roll 11, the pair of support portions 12, 12, the bag body 14, and the pair of flanges 15 and 15 having the above configuration further has a lid portion 26 (FIG. See 1). Fitting recesses 26a opened downward are provided at the four corners of the lid 26, and the lid 26 can be fitted into the box body by fitting the fitting protrusions 18a protruding upward from the four corners of the frame 18. 13 is closed.

Hereinafter, an example of a method for manufacturing the glass roll packing body 10 having the above configuration, in other words, an example of a method for loading the glass roll 11 into the box body 13 will be described with reference to FIGS. 6 to 10.

First, as shown in FIG. 6, the frame body 18 of the box body 13 is prepared, and the bag body 14 is installed inside the frame body 18. At this time, the bag body 14 is installed so that the opening 24 of the bag body 14 faces upward. At this point (point before loading the glass roll 11), the plate-like body 19 is in a removed state. At this time, in order to facilitate the introduction of the glass roll 11 described later into the bag body 14, as shown in FIG. 6, the edge 24a of the opening 24 may be installed in a state of being folded outward.

Then, for example, as shown in FIG. 4, a long glass film G is wound around the winding core 16 together with the cushioning sheet 17, and a pair of flanges 15 are formed on both axially side portions 16b and 16b of the winding core 16. A glass roll 11 to which the 15 is attached is prepared, and the prepared glass roll 11 is introduced into the bag body 14 through the opening 24 (see FIG. 7). At this time, the axially both side portions 16b and 16b of the winding core 16 are placed on the pair of support portions 12 and 12 via the bag body 14 (state shown in FIG. 5). , 16b and the entire glass roll 11 are introduced into the bag body 14.

After introducing the glass roll 11 into the bag body 14 in this way, the opening 24 of the bag body 14 is closed. As a result, as shown in FIG. 8, the entire glass roll 11 including the axially both side portions 16b and 16b of the winding core 16 and the pair of flanges 15 and 15 is covered with the bag body 14 and is shielded (sealed) from the outside air. It will be in a state of being. In this case, the closing portion 25 of the bag body 14 is formed above the glass roll 11.

In the present embodiment, as described above, the entire glass roll 11 is housed inside the bag body 14, the opening 24 is closed, and then the upper support portion 21 is rotated around the rotation shaft 22 to lower the lower side. It is moved above the support portion 20 (see FIG. 3). Then, by fixing the upper support portion 21 to the lower support portion 20 by bolting or the like, the axially both side portions 16b and 16b of the winding core 16 are sandwiched. As a result, the axially both side portions 16b and 16b of the winding core 16 are supported by the support surface 20a of the lower support portion 20 via the bag body 14, and the support surface of the upper support portion 21 is supported via the bag body 14. It is in a state of being supported by 21a (see FIG. 9).

After that, the four plate-shaped bodies 19 are inserted into the insertion portion 23 of the frame body 18 from the upper side to the lower side. As a result, the four sides of the glass roll 11 are covered with the plate-shaped body 19 (see FIG. 10).

Finally, the glass roll packing body 10 is completed by fitting the lid portion 26 into the upper part of the frame body 18.

As described above, according to the glass roll packing body 10 according to the present invention, the entire glass roll 11 including the axially both side portions 16b and 16b of the winding core 16 is a bag body in a state of being housed in the box body 13. It becomes a form covered with 14. Therefore, simply by accommodating the glass roll 11 inside the bag body 14, the entire glass film G wound into a roll shape is covered with the bag body 14, and the glass film G can be protected from the outside air. .. As a result, it is possible to prevent the situation where the outside air is exposed to the glass film G and the situation where foreign matter adheres to the glass film G more easily than before. Of course, since it is only necessary to prepare the bag body 14, the glass film G can be protected from the outside air at a lower cost than, for example, processing the box body 13 into a closed structure.

Further, in the method for manufacturing the package of the glass roll 11 according to the present embodiment, the entire glass roll 11 is housed inside the bag body 14 which has been installed inside the box body 13 with the opening 24 facing upward in advance. At the same time, the axially both side portions 16b, 16b of the winding core 16 are placed on the pair of support portions 12, 12. Then, the opening 24 of the bag body 14 is closed. As a result, the glass roll 11 is housed in the box body 13, and the entire glass roll 11 is covered with the bag body 14 and supported by the pair of support portions 12, 12. Therefore, according to the method for producing the present packaging body, the glass roll 11 can be loaded inside the box body 13 and packed with a small number of man-hours. Further, when taking out the glass roll 11, it is sufficient to take out the glass roll 11 together with the winding core 16 regardless of whether the box body 13 is opened and the bag body 14 is opened or closed. Therefore, the glass roll 11 is taken out from the box body. It is also possible to easily take out from 13.

Further, in the present embodiment, a bag body 14 having an opening 24 at one location is used (see FIG. 1). If there is only one opening 24, the entire glass roll 11 is housed inside the bag body 14, and then only one opening is closed, so that the work is easy. Further, if the opening 24 is closed at a position away from the winding core 16, it is possible to save the trouble of tying the opening 24 around the winding core 16 and closing the opening, so that the work is easy. In particular, as in the present embodiment, by providing the lid portion 26 above the box body 13 and providing the opening portion 25 above the glass roll 11, the opening portion 24 can be easily closed while avoiding interference with the surroundings. Further, when the glass roll 11 is taken out at the transport destination, the lid portion 26 can be removed and the bag body 14 can be immediately opened from above.

Further, as in the present embodiment, when the box body 13 has a frame body 18 and a plurality of plate-shaped bodies 19 which have an outer wall of the box body 13 and are detachably attached to the frame body 18, the box body The accessibility to the glass roll 11 in the state of being housed in the 13 can be improved. That is, by removing the lid portion 26 and removing the plate-shaped body 19, the winding core 16 in a state of being supported by the support portions 12 and 12 provided on the frame body 18 is directly accessed from the side of the box body 13. can do. Therefore, the winding core 16 can be easily lifted and the glass roll 11 can be taken out from the box body 13 and the bag body 14.

Further, in the present embodiment, a pair of flanges 15 and 15 facing the entire width direction end surface of the glass film G via a predetermined gap are attached to both side portions 16b and 16b of the winding core 16 in the axial direction. Therefore, for example, even if the entire glass roll 11 moves in the width direction, it is possible to surely avoid the situation where the widthwise end face of the glass film G comes into contact with the support portion 12 and surely prevent the end face from being damaged. it can. Further, at this time, by covering both the entire glass roll 11 and the pair of flanges 15 and 15 with the bag body 14, the flange 15 restricts the movement of the bag body 14 to the roll portion 11a, and the roll portion 11a A certain space can be formed between the outer peripheral surface and the bag body 14 (see FIG. 5). This makes it possible to reliably prevent contamination and breakage of the glass film G due to unnecessary contact between the bag body 14 and the glass roll 11.

Although one embodiment of the present invention has been described above, the glass roll package according to the present invention and the method for producing the same are not limited to the above embodiments, and various forms are adopted within the scope of the present invention. It is possible.

For example, in the above embodiment, the case where the bag body 14 having the opening 24 at one place is arranged in the box body 13 is illustrated, but the bag body 14 having an opening form other than this is adopted. Is also possible. For example, although not shown, a bag body having two or more openings 24 can be adopted. Further, the form of the bag body 14 having the opening 24 at one place is also arbitrary, for example, bottom seal type, side seal type, three-way seal type, pillow type (one film is sealed back to back to form a tubular shape. It is also possible to adopt a bag body 14 having a known form such as a mold formed by sealing one opening) or a gusset mold. Alternatively, even if it is a sheet-like body, it can be a bag body 14 depending on the packing form. For example, the glass roll 11 may be placed on a sheet-like body such as a resin film, and the glass roll 11 may be wrapped with the film so that the entire glass roll 11 is covered. Further, in the above embodiment, the bag body 14 is arranged inside the box body 13 with the opening 24 facing upward in advance, and the glass roll 11 is introduced from above to make the entire glass roll 11 into the bag body 14. Although the case of covering is illustrated, other aspects can be adopted. For example, a bag body 14 in which the entire glass roll 11 is housed in advance may be housed inside the box body 13. Further, in this case, the opening 24 of the bag body 14 may be closed first, and then the bag body 13 may be housed inside the box body 13. In short, the entire glass roll 11 including the axial side portions 16b and 16b of the winding core 16 is covered with the bag body 14, and the axial side side portions 16b and 16b of the winding core 16 are a pair of supporting portions 12 and 12. As long as it is supported by the above, the form of the bag body 14 and the form of accommodating the glass roll 11 by the bag body 14 are arbitrary.

Further, in the above embodiment, the case where the support surface 20a of the lower support portion 20 is formed by a pair of slopes that approach each other as it goes downward is illustrated (see FIG. 3), but of course, the support surface 20a is , It is also possible to take a form other than the above. Further, at that time, it does not particularly matter whether the winding core 16 is in point contact or surface contact with the outer peripheral surface of the axial side portion 16b. Although the support surface 20a of the lower support portion 20 has been described above, the support surface 21a of the upper support portion 21 can also take any form in the same manner. For example, the support surface 21a of the upper support portion 12 may be formed by a pair of slopes like the support surface 20a of the lower support portion.

Further, in the above embodiment, the case where the axial side portion 16b of the winding core 16 is sandwiched and fixed from above and below by the lower support portion 20 and the upper support portion 21 divided in the upper and lower parts is illustrated. Is not limited. For example, although not shown, if the glass roll 11 is restricted from being lifted upward by a configuration other than the support portion 12, the support portion is supported only by the lower support portion 20 that supports the lower side of the outer peripheral surface of the winding core 16. 12 may be configured.

Further, in the above embodiment, the case where the axially both side portions 16b and 16b of the winding core 16 are directly supported by the pair of supporting portions 12 and 12 is illustrated, but the present invention is not limited to this embodiment. The present invention also includes a form in which both axially side portions 16b, 16b of the winding core 16 are supported by a pair of support portions 12, 12 via a flange 15.
