Description

Glass roll packing body and manufacturing method thereof

The invention relates to a glass roll packing body and a manufacturing method thereof.

As is well known, in recent years, various glass plates including glass substrates for flat panel displays, such as liquid crystal displays, plasma displays, organic electroluminescence (EL) displays, and field emission displays, are required to be further thinned. Therefore, in response to this request, the development of so-called glass films that have been thinned to a film shape has been advanced, and for example, glass films having a thickness of 200 μm or less have been developed.

In addition, as a packing form of the glass film, a glass roll formed by winding a glass film around a winding core in a roll shape is being promoted. This type of packing is focused on the flexibility of the glass film, and has various advantages such as space saving. Therefore, it has attracted attention as a packing form suitable for the glass film.

In addition, depending on the application, this glass product (glass film) requires high surface quality (such as cleanliness). Therefore, when the glass film is packaged in the form of a glass roll for transportation, it is necessary to prevent the adhesion of foreign matter. Or corrosive conditions that cause contamination of the glass roll.

Here, for example, in Patent Document 1, as a packaging container for a glass roll, a packaging container for a glass roll is disclosed, which is characterized by including a box body in which a storage room for storing a glass roll is formed; and a cover member , Installed in the opening of the box to seal the storage room; and a humidity adjustment unit to adjust the humidity of the storage room; and the storage room is adjusted to a dry state by the humidity adjustment unit after the glass roll is stored.

[Problems to be Solved by the Invention]
In this way, if it is the packing container described in Patent Document 1, the storage room of the glass roll provided inside the box can be closed, so it can be considered that the invasion of outside air can be effectively prevented, and furthermore, it can be effectively prevented. Adhesion of foreign matter that has invaded the inside of the cabinet with outside air to the glass film. However, if the inside of the box is intended to be sealed as described in Patent Document 1, the structure of the packing container including the box is complicated. In this case, there is a possibility that the manufacturing cost of the packaging container will increase, which is not preferable.

In view of the above circumstances, it is a technical problem to be solved by the present invention that a glass roll package having a simple structure and capable of preventing contamination of the glass roll is produced.
[Means for solving problems]

The said subject is solved by the glass roll package of this invention. That is, the package body includes a glass roll formed by winding a glass film around the core in a roll shape in a state where both sides of the core in the axial direction have been exposed, and a case having a support for the core. A pair of support portions on both sides in the axial direction, and accommodates a glass roll in a state supported by the pair of support portions; and is characterized in that the entire glass roll is covered by a bag body, and is supported by the pair Ministry to support glass rolls.

As described above, in the packing body of the present invention, the entire glass roll is covered with the bag body in a state where it has been stored in the box body. Therefore, only the glass roll can be stored inside the bag body. The entire state of the rolled glass film is covered by the bag body, and the glass film is protected from outside air. This makes it easier than ever to prevent the glass film from being exposed to the outside air, thereby preventing the foreign matter from adhering. Of course, it is only necessary to prepare a bag body, and therefore, it is possible to protect the glass film from outside air at a lower cost than when the box body is processed into a closed structure, for example.

In addition, in the packing body of the present invention, as described above, in a state where the entire glass roll is covered with the bag body, the glass roll is supported by a pair of support portions. Therefore, for example, by following Sequentially, the glass roll can be easily packed into the box for packing. That is, the entire glass roll is housed in a bag body which is provided in the interior of the box in advance, and both sides in the axial direction of the roll core are placed on a pair of support portions. Then, the bag body is sealed. Thereby, the glass roll is accommodated in a box body, and the whole glass roll is supported by a pair of support part in the state covered with the bag body. Based on the above, according to the present invention, it is possible to pack a glass roll into a box with a relatively small workload. In addition, when taking out the glass roll, it is only necessary to open the box and take out the glass roll together with the roll core. Therefore, the glass roll can also be easily taken out from the box.

Moreover, in the glass roll packing body of this invention, a bag body may be a thing which has an opening part in one place.

In this way, if the bag is provided with an opening in one place, the entire glass roll including the core can be stored in the bag through the opening, and then one of the places can be sealed, so it can be easily used. The bag body covers the entire glass roll.

In addition, in the glass roll package of the present invention, on both sides in the axial direction of the roll core, a predetermined distance from the widthwise end surface of the glass film and facing the entire area of the widthwise end surface may be installed, respectively. Flange. In addition, the width direction mentioned here means the direction along the winding center of a glass film.

In this way, the flanges are provided on both sides in the axial direction of the winding core, so that, for example, when the entire glass roll has been moved in the width direction, the situation in which the widthwise end surface of the glass film is in contact with the case can be reliably avoided. Ground to prevent breakage of this end face.

In addition, in the case of the flange having the above-mentioned structure, in the glass roll packaging body of the present invention, the bag body may cover the entire glass roll and the flange at the same time.

The bag body not only covers the glass roll including the core and the glass film, but also covers the flange installed on the core, whereby the flange can restrict the movement of the bag toward the glass roll, and the outer peripheral surface of the glass roll and the bag body are covered by the flange. To form a fixed space. This can reliably prevent the glass film from being contaminated or broken due to unnecessary contact between the bag body and the glass roll.

In addition, in the glass roll package of the present invention, it is possible to prevent the glass roll from falling from the support part on either side due to the movement in the width direction by contact between the flange and the support part. Set the gap between the flange and the support.

By setting the gap between the flange and the support portion in this way, even if the glass roll has deviated in the width direction during transportation, the flange restricts the width of the glass roll at a predetermined position, so the shaft of the core can be reliably prevented Directions from side to side support the situation under the tribe.

In addition, in the glass roll package of the present invention, the support portion is divided up and down, and includes a lower support portion that supports the lower side of the outer peripheral surface of the core, an upper support portion that supports the upper side of the outer peripheral surface, and an upper support portion. It is supported so as to be rotatable around a predetermined rotation axis, thereby being movable between a support position of the winding core and a retreat position separated from the support position.

In this way, by having a structure in which the support portion is divided up and down, the core of the glass roll can be easily placed on the support portion or detached from the support portion. In addition, at this time, the divided upper support portion is supported so as to be rotatable around a predetermined rotation axis, so that the upper support portion can be easily moved between the support position of the winding core and the retracted position. Therefore, when the glass roll is loaded, the upper support portion is first retracted from the space above the lower support portion (that is, the support position of the roll core). After the glass roll is placed, the upper support portion is rotated around a predetermined rotation axis. And abut on the outer peripheral surface of the core. Then, the upper support portion is fixed to the lower support portion, whereby the winding core can be easily clamped and fixed by the upper and lower support portions. In addition, when taking out the glass roll, firstly only the upper support part is rotated around the rotation axis, and it is retracted from the space above the lower support part, and the glass roll can be lifted upward to be taken out from the inside of the cabinet. Based on the above, according to the support portion of the structure, the glass roll can be loaded and unloaded efficiently.

In addition, in the glass roll package of the present invention, the box may include a frame body and a plurality of plate-like bodies that form an outer wall of the box body and are detachably attached to the frame body.

As described above, by adopting a structure in which the plate-like body forming the outer wall of the case is detachably attached to the frame of the case, the accessibility to the glass roll in a state of being accommodated in the case can be improved. That is, by removing the plate-like body, the roll core in a state supported by the support portion provided in the frame body can be accessed from the side of the case, and therefore the roll core can be easily lifted to take out the glass roll. Of course, when the glass roll is loaded, the core of the glass roll can be placed on the support in a state in which the plate-shaped body located outside the support has been removed, so that the glass roll can be easily stored in the box. Inside the body.

In addition, when the box body has a frame body and a plurality of plate-like bodies, in the glass roll packaging body of the present invention, a pair of support portions may be formed by a part of the frame body, and the ratio support portion of the frame body may be Further, an insertion portion is provided to allow the plate-shaped body to be inserted.

Thus, if a pair of support parts are comprised by a part of frame, a box can be simplified further and it can contribute to miniaturization. In addition, the frame body is provided on the outer side than the support portion, and an insertion portion through which the plate-shaped body can be inserted is provided, whereby the plate-shaped body can be easily attached to and detached from the frame body. This makes it possible to further improve workability related to loading or unloading the glass roll.

In addition, the above-mentioned problem is also solved by the manufacturing method of the glass roll package of this invention. That is, this manufacturing method is characterized by including the steps of: manufacturing a glass roll by winding a glass film around the core in a roll shape in a state where both sides of the core in the axial direction are exposed; A step of supporting the inside of the box of the pair of support portions on both sides in the axial direction of the core; while accommodating the entire glass roll including both sides in the axial direction of the core in the bag, the shaft of the core A step of placing both sides of the direction on a pair of support portions; and a step of sealing the bag body.

As described above, according to the method for producing a packaging body according to the present invention, just by storing the glass roll in the bag body, it is possible to cover the glass film which has been wound into a roll shape with the bag body. The overall state protects the glass film from outside air. This makes it easier than ever to prevent the glass film from being exposed to the outside air, thereby preventing the foreign matter from adhering. Of course, it is only necessary to prepare a bag body, and therefore, it is possible to protect the glass film from outside air at a lower cost than when the box body is processed into a closed structure, for example. In addition, while the entire glass roll is housed in a bag body which is provided in the interior of the box in advance, both sides of the roll core in the axial direction are placed on a pair of support portions, and then the bag body is sealed, thereby becoming The glass roll is housed in a box, and the entire glass roll is supported by a pair of support portions in a state covered by the bag body. Therefore, according to the present invention, it is possible to pack glass rolls into a box with a relatively small workload. In addition, when taking out the glass roll, it is only necessary to open the box and take out the glass roll together with the roll core. Therefore, the glass roll can also be easily taken out from the box.
[Effect of the invention]

As described above, according to the present invention, a glass roll package body having a simple structure and capable of preventing contamination of the glass roll can be produced.

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 package 10 of the present embodiment, FIG. 2 is a plan view of the same glass roll package 10, and FIG. 3 is a side view of the same glass roll package 10. As shown in these figures, the glass roll packing body 10 includes: a glass roll 11; a box 13 having a pair of support portions 12, 12 supporting the glass roll 11 and containing the glass roll 11; and a bag body 14 covering Glass roll 11 as a whole. In the present embodiment, the glass roll package 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 packaged is obtained by winding a long glass film G around a winding core 16. In the present embodiment, the glass film G and the buffer sheet 17 are wound. In a state of being overlapped, the outer peripheral surface of the core 16 is wound into a roll shape.

For example, as shown in FIG. 4, the winding core 16 is formed in the hollow cylindrical shape which has the hole part 16a. In addition, the axial direction side portions 16b and 16b of the core 16 are portions exposed in a state where the glass film G has been wound in a roll shape, and if the view is changed, it is equivalent to a glass film wound in a roll shape. A portion where both end surfaces in the width direction of G protrude further in the width direction of the glass film G. In addition, the winding core 16 is not limited to the hollow cylindrical shape illustrated in the figure, and may be, for example, a solid cylindrical shape.

The material of the core 16 is not limited as long as there is no problem in strength. For example, metal such as aluminum alloy, stainless steel, manganese steel, carbon steel, phenol resin, urea resin, melamine resin, unsaturated polyester resin, epoxy resin, Thermosetting resins such as polyurethane and diallyl terephthalate resin, polyethylene, polypropylene, polystyrene, Acrylonitrile Styrene (AS) resin, acrylonitrile-butadiene Acrylonitrile Butadiene Styrene (ABS) resin, thermoplastic resins such as methacrylic resin, vinyl chloride, or reinforced plastics made by blending reinforcing materials such as glass fiber or carbon fiber with these thermosetting resins or thermoplastic resins, Paper or the like is used as the material of the roll core 16.

The glass film G is formed by, for example, an overflow down draw method, and the thickness is set to a 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 this numerical range, moderate flexibility and strength can be imparted to the glass film G, and there is no obstacle during winding.

The width 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 even more preferably 1000 mm or more. Furthermore, since the glass film G is used in various devices from small-screen displays such as small mobile phones to large-screen displays such as large television receivers, the width of the glass film G is ultimately better. It is appropriately selected in accordance with the size of the substrate of the equipment used.

As the glass composition of the glass film G, various glass compositions such as silicate glass such as silica glass and borosilicate glass can be used, but it is preferable to use an alkali-free glass depending on the application. The reason is that if the glass film G contains an alkali component, a phenomenon called so-called out-of-alkali occurs, and a part of the glass film G becomes thick in structure. When the glass film G has been bent, there is a period of time. Deterioration may cause damage from structurally thickened parts. Moreover, when the glass film G contains an alkali component, when the glass film G is used for a glass substrate use, there exists a possibility that the characteristic of the thin film formed on the surface may be impaired. In addition, the alkali-free glass mentioned here means the glass which does not substantially contain an alkali component, and specifically means that an alkali metal oxide is 3000 ppm or less (preferably 500 ppm or less, more preferably 300 ppm or less).

From the viewpoint of protecting the glass film G, the buffer sheet 17 is wound around the winding core 16 in a state where it has overlapped with the glass film G, and the winding is completed (the state shown in FIG. 1 or FIG. 4). Next, they are inserted between the glass films G. At this time, the buffer sheet 17 is arranged so as to cover the entire area of the front and back surfaces (the first main surface and the second main surface) of the glass film G, thereby protecting the entire area of the front and back surfaces of the glass film G. Furthermore, from the viewpoint of protecting the glass film G, it is preferable that the buffer sheet 17 is positioned on the innermost side and the outermost side of the roll portion 11a in a state where the winding of the glass film G with respect to the core 16 is completed. Outside diameter side. From the same viewpoint, the buffer sheet 17 is preferably exposed from both end surfaces in the width direction of the glass film G. Of course, the widthwise both end surfaces of the buffer sheet 17 and the widthwise both end surfaces of the glass film G may coincide at the same width direction position, or the glass film G may also be exposed from the widthwise both end surfaces of the buffer sheet 17.

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

In principle, the material of the buffer sheet 17 is arbitrary, and for example, laminated paper or non-woven fabric can be applied. In addition to the materials exemplified above, for example, ionic polymers, polyethylene, polyethylene terephthalate, polypropylene, polyvinyl chloride, polyvinylidene chloride, polyvinyl alcohol, and polyester can be applied. , Polycarbonate, polystyrene, polyacrylonitrile, ethylene-vinyl acetate copolymer, ethylene-vinyl alcohol copolymer, ethylene-methacrylic acid copolymer, nylon (polyimide), polyimide, celluloid Resin sheet made of resin. Furthermore, from the viewpoint of ensuring both cushioning performance and strength, it is preferable to use a foamed resin sheet made of a foamed resin such as polyethylene as the cushion sheet 17. From the viewpoint of improving the sliding property with the glass film G, it is preferable to use a resin sheet formed by dispersing silicon dioxide or the like in the resin as the buffer sheet 17. In this case, the offset between the glass film G and the buffer sheet 17 can be absorbed by the sliding property of the resin sheet.

In the present embodiment, a pair of flanges 15 and 15 are attached to the core 16 of the glass roll 11. These flanges 15 and 15 are attached to both axial-direction side portions 16 b and 16 b of the core 16, and the entire area of the widthwise end surface of the glass film G faces the widthwise end surface of the glass film G (see FIG. 2). That is, the outer diameter dimension of the flange 15 is larger than the outer diameter dimension of the roll part 11a which wound the glass film G around the winding core 16. In this embodiment, each flange 15 faces the widthwise end surface of the glass film G in a width direction with a predetermined gap therebetween.

Each of the flanges 15 may be, for example, a disc-shaped integral body. However, in this embodiment, as shown in FIG. 4, each of the flanges 15 includes a first divided plate 15 a and a second divided plate 15 b each having a semi-disc shape. In this case, in a state where the first divided plates 15a, 15a and the second divided plates 15b, 15b using the flanges 15 are sandwiched in the axial direction side portions 16b, 16b of the core 16, respectively, for example, A pair of flanges 15 and 15, which are integrally formed into a disk shape, are fixed to the outer periphery of the core 16 by connecting the first divided plate 15 a and the second divided plate 15 b with bolts or the like.

In addition, in the present embodiment, in order to reduce the processing cost, the outer peripheral surface of the core 16 is formed in a shape with a fixed outer diameter. However, in order to accurately locate the axis of the flange 15 of the core 16 in the axial direction, For example, although illustration is omitted, a step may be provided on the outer periphery of the core 16 so that the flange 15 abuts on the step in the axial direction.

The box 13 is formed into a substantially rectangular parallelepiped shape as a whole. In this embodiment, the box 13 includes a frame body 18 and a plurality of plate-shaped bodies 19 (refer to FIG. 1) that form an outer wall of the box 13 and are detachably mounted to the frame body 18. ). In this case, the glass roll 11 and the bag body 14 are housed inside the box 13. In addition, a pair of support portions 12 and 12 are provided on the frame 18, and the glass roll 11 that has been housed inside the case 13 is supported by the pair of support portions 12 and 12.

To explain in detail, as shown in FIG. 3, the pair of support portions 12 and 12 support the axial-direction both side portions 16 b and 16 b of the core 16. At this time, as shown in FIG. 5, both side portions 16 b and 16 b in the axial direction of the core 16 are supported by the pair of support portions 12 and 12 via the bag body 14.

Here, in this embodiment, as shown in FIG. 3, each support portion 12 is divided vertically, and includes a lower support portion 20 that supports the lower side of the outer peripheral surface of each axial direction side portion 16b, and supports each axial direction side portion. The upper side support part 21 on the outer peripheral surface of 16b. In addition, the upper support portion 21 is supported so as to be rotatable around a predetermined rotation shaft 22 provided on the frame body 18, so that the upper support portion 21 can be positioned above the lower support portion 20 (that is, in FIG. 3). The support position of the core 16 shown) is moved between the retracted position (refer to FIG. 1) and the retracted position from the support position.

In this embodiment, the lower support portion 20 is formed by deforming a part of the frame body 18, and the support surface 20a of the lower support portion 20 is formed by a pair of inclined surfaces that approach each other as they go downward (see FIG. 3). . In addition, in this embodiment, the upper support portion 21 has a substantially semi-circular curved portion formed separately from the frame body 18, and the support surface 21a of the upper support portion 21 is formed by an inner peripheral surface forming a semi-circular curved portion. . In this case, in a state where the upper support portion 21 is rotated around the rotation shaft 22 and has been moved above the lower support portion 20, the axial direction side portion of the core 16 that is the object of support can be clamped from the up and down direction. 16b (see Figure 3).

In addition, when a pair of flanges 15 and 15 are mounted on the core 16 of the glass roll 11, the flange 15 and the supporting portion 12 (here, the lower supporting portion 20) are prevented from contacting each other to prevent the The method of dropping the self-supporting portion 12 of the glass roll 11 caused by the movement sets the gap g1 between each flange 15 and the frame 18 to a predetermined size or less (see FIGS. 2 and 5). In other words, the gap g1 is set so that the axial direction side portion 16b of the core 16 on the side opposite to the moving direction remains on the support portion 12 even if the glass roll 11 moves by a distance corresponding to the gap g1 in the width direction. It should be less than the specified size. 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. The gaps g1 and g2 function as clearances when the glass roll 11 is housed inside the box 13. Therefore, from the viewpoint of loadability, the gaps g1 and g2 are also set to Some size is appropriate.

In addition, in the present embodiment, an insertion portion 23 (see FIGS. 1 to 3) is provided on the frame body 18 outside the support portion 12 so that the plate-shaped body 19 can be inserted downward. The insertion portion 23 is formed in a groove shape, for example, and is fitted into the bottom edge 19 a and the pair of side edges 19 b and 19 b of the inserted plate-shaped body 19. Of course, the insertion direction of the plate-shaped body 19 is not limited to the downward direction. For example, although the illustration is omitted, the insertion portion 23 may be configured such that the plate-shaped body 19 in the vertical posture is slid in the horizontal direction to be provided at a position forming the outer wall of the frame body 18.

In this embodiment, the bag body 14 has an opening portion 24 at one location. As shown in FIG. 1, the bag body 14 can be arranged with the opening portion 24 facing upward while being housed inside the case 13. Moreover, the opening part 24 has a magnitude | size which can pass through the glass roll 11 of the state which attached the pair of flanges 15 and 15 to the axial direction both sides 16b and 16b of the core 16. At this time, as shown in FIG. 1, it is preferable to set the size and shape of the opening portion 24 to such an extent that the glass roll 11 can be oriented in the width direction of the glass roll 11 (the longitudinal direction of the core 16). ) The degree of penetration into a roughly horizontal posture.

As shown in FIG. 2 and FIG. 3, the bag body 14 having the above structure accommodates the entire glass roll 11 including both sides 16 b and 16 b in the axial direction of the core 16. In this embodiment, the entire glass roll 11 including a pair of flanges 15 and 15 is housed inside the bag body 14. In this case, the opening portion 24 (see FIG. 1) of the bag body 14 is in a state of being sealed above the glass roll 11. In other words, a sealing portion formed by closing the opening portion 24 is formed above the glass roll 11. 25. In addition, in this case, the flange 15 and the bag body 14 may also be in contact with each other, or the bag body 14 may be partially unfolded by positive contact, thereby ensuring the outer peripheral surface of the bag body 14 and the roll portion 11a of the glass roll 11 Distance (see Figure 5).

In this embodiment, the box 13 formed by accommodating the glass roll 11 having the above-mentioned structure, a pair of support portions 12 and 12, a bag 14, and a pair of flanges 15 and 15 further has a cover portion 26 (see figure 1). Fitting recesses 26 a that open downward are provided at the four corners of the cover portion 26, and fit into the fitting convex portions 18 a that protrude upward from the four corners of the frame body 18 respectively, whereby the cover portion 26 seals the box 13.

Hereinafter, an example of the manufacturing method of the glass roll package 10 of the said structure is demonstrated centering on FIG. 6-10, In other words, an example of the installation method of the glass roll 11 into the inside of the case 13 is demonstrated.

First, as shown in FIG. 6, the frame body 18 of the box body 13 is prepared, and the bag body 14 is provided inside the frame body 18. At this time, the bag body 14 is installed so that the opening portion 24 of the bag body 14 faces upward. At this point in time (time before the roll of glass 11 is loaded), the plate-like body 19 is in a state of being removed. In addition, 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 portion 24 may be folded outward. .

Then, for example, as shown in FIG. 4, a long glass film G is prepared to be wound around the winding core 16 together with the buffer sheet 17, and a pair of flanges 15 and 16 are mounted on both sides 16 b and 16 b of the winding core 16 in the axial direction. The prepared glass roll 11 is introduced into the bag body 14 through the opening 24 (see FIG. 7). At this time, both sides in the axial direction of the core 16 are placed on the pair of supporting portions 12 and 12 via the bag body 14 (the state shown in FIG. 5), and both sides in the axial direction are included. The glass rolls 11 of the portions 16b, 16b are introduced into the bag body 14 as a whole.

After the glass roll 11 is introduced into the bag body 14 as described above, the opening portion 24 of the bag body 14 is closed. Thereby, as shown in FIG. 8, the glass roll 11 including both sides 16 b and 16 b in the axial direction of the core 16 and the pair of flanges 15 and 15 is covered by the bag body 14 and is sealed from the outside air (closed). status. In this case, the sealing portion 25 of the bag body 14 is formed above the glass roll 11.

In this embodiment, as described above, the entire glass roll 11 is housed inside the bag body 14 and the opening portion 24 is closed. Then, the upper support portion 21 is rotated around the rotation shaft 22 and moved to the lower support portion 20. Above (see Figure 3). Then, the upper side support portion 21 is fixed to the lower side support portion 20 by bolting or the like, whereby the axial direction side portions 16 b and 16 b of the winding core 16 are clamped. Thereby, both sides 16b, 16b in the axial direction of the core 16 are supported by the support surface 20a of the lower support portion 20 via the bag body 14, and are supported by the support surface 21a of the upper support portion 21 via the bag body 14. Status (see Figure 9).

Then, the four plate-shaped bodies 19 are inserted into the insertion portion 23 of the frame body 18 from above to below. Thereby, the periphery of the glass roll 11 is covered with the plate-shaped body 19 (refer FIG. 10).

Finally, the lid portion 26 is finally fitted into the upper portion of the frame body 18, whereby the glass roll packing body 10 is completed.

As described above, according to the glass roll package 10 according to the present invention, the glass roll 11 including both sides 16b and 16b in the axial direction of the core 16 has been completely contained in a bag in a state of being accommodated in the case 13 Body 14 covers the form. Therefore, only when the glass roll 11 is housed inside the bag body 14, the entire glass film G that has been wound into a roll shape is covered by the bag body 14, and the glass film G can be protected from outside air. With this, it is possible to prevent the state where the glass film G is exposed to the outside air more easily than before, thereby preventing the state where foreign matter is attached. Of course, only the bag body 14 needs to be prepared, and therefore, the glass film G can be protected from outside air at a lower cost than when the box body 13 is processed into a closed structure, for example.

In addition, in the method for manufacturing the package body of the glass roll 11 according to the present embodiment, the entire glass roll 11 is housed inside the bag body 14 which is provided inside the box 13 with the opening 24 facing upward in advance, Both sides 16b and 16b in the axial direction of the core 16 are placed on the pair of support portions 12 and 12. Then, the opening portion 24 of the bag body 14 is closed. Thereby, the glass roll 11 can be accommodated in the case 13, and the whole glass roll 11 can be supported by the pair of support parts 12 and 12 in the state covered with the bag body 14. Therefore, according to the manufacturing method of this packing body, it is possible to pack the glass roll 11 into the inside of the box body 13 with a small workload. In addition, when the glass roll 11 is taken out, only the box 13 is opened, and the glass roll 11 can be taken out together with the core 16 regardless of whether the bag 14 is opened or the bag 14 is sealed. The glass roll 11 can also be easily taken out from the case 13.

In addition, in the present embodiment, a bag body 14 (see FIG. 1) having an opening portion 24 at one portion is used. If the opening portion 24 is a single portion, it is only necessary to seal one portion after the entire glass roll 11 is housed inside the bag body 14, and thus the operation is easy. In addition, if the opening portion 24 is sealed at a position separated from the winding core 16, the time and the like of bundling around the winding core 16 to perform sealing and the like can be omitted, and the operation is also easy. In particular, by providing a cover portion 26 above the box 13 and a sealing portion 25 above the glass roll 11 as in this embodiment, the opening portion 24 can be easily sealed without interference with the surroundings. In addition, when When the glass roll 11 is taken out at the transport destination, the lid portion 26 can be removed, and the unsealing operation of the bag body 14 can be immediately performed from above.

In addition, as in the present embodiment, the case 13 has a frame 18 and a plurality of plate-shaped bodies 19 that form an outer wall of the box 13 and are detachably mounted to the frame 18, which can improve the performance of Proximity of the glass roll 11 in a state accommodated in the case 13. That is, the plate-shaped body 19 is removed by removing the cover portion 26, and the core 16 can be directly approached from the side of the case 13 by the support portions 12 and 12 provided in the frame body 18. Therefore, the roll core 16 can be easily lifted to take out the glass roll 11 from the box 13 and the bag 14.

In addition, in the present embodiment, the axial direction side portions 16b and 16b of the winding core 16 are provided with a predetermined gap from the widthwise end surface of the glass film G and face the entire area of the widthwise end surface of the glass film G. The pair of flanges 15 and 15 can reliably prevent the widthwise end surface of the glass film G from contacting the support portion 12 even if the entire glass roll has been moved in the width direction, and can reliably prevent the end surface. damaged. In addition, at this time, the entire glass roll 11 and a pair of flanges 15 and 15 are simultaneously covered by the bag body 14, whereby the flange 15 can restrict the movement of the bag body 14 toward the roll portion 11a, and the outer periphery of the roll portion 11a A fixed space is formed between the surface and the bag body 14 (see FIG. 5). This can reliably prevent the glass film G from being contaminated or broken due to unnecessary contact between the bag body 14 and the glass roll 11.

In addition, in this case, the opening portion 24 of the bag body 14 may be sealed first, and then stored in the case 13. In short, as long as the entire glass roll 11 including the axial direction side portions 16 b and 16 b of the core 16 is covered by the bag body 14, the axial direction side portions 16 b and 16 b of the core 16 are supported by a pair of support portions 12. The shape of the bag body 14 and the shape in which the glass roll 11 is accommodated by the bag body 14 are arbitrary.

Moreover, in the said embodiment, the case where the support surface 20a of the lower support part 20 was formed with the pair of inclined surfaces which approached each other as it went downward is shown (refer FIG. 3), Of course, you may use the support surface 20a. Other than the above. In addition, at this time, there is no particular limitation on whether point contact or surface contact is made with the outer peripheral surface of the axial direction side portion 16 b of the core 16. The support surface 20a of the lower support portion 20 has been described above. However, the support surface 21a of the upper support portion 21 may be similarly adopted in an arbitrary form. For example, similarly to the support surface 20a of the lower support portion, the support surface 21a of the upper support portion 12 may be formed by a pair of inclined surfaces.
