Description

TECHNICAL FIELD The present invention relates to a glass roll package and a manufacturing method thereof.

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 this demand, the development of so-called glass films, which are thinned into films, is underway. 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, in which the glass film is wound around a winding core, is being adopted. Such a packing form focuses on the flexibility of the glass film, and has various advantages such as space saving. Therefore, it is attracting attention as a packing form suitable for the glass film.

By the way, this type of glass product (glass film) is required to have a high surface quality (for example, cleanliness) depending on the application. Therefore, it is necessary to prevent 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 a glass roll, a box body having a storage chamber in which the glass roll is stored is formed, and a lid member attached to the opening of the box body and sealing the storage chamber. and a humidity adjustment unit for adjusting the humidity of the storage chamber, and the storage chamber is adjusted to a dry state by the humidity adjustment unit after the glass roll is stored. It is

In this way, with the packaging container described in Patent Document 1, the storage chamber for the glass roll provided inside the box can be kept in a sealed state, so that outside air can enter, and foreign matter entering the inside of the box along with the outside air can be prevented. It seems that adhesion to the glass film can be effectively prevented. However, when trying to seal the inside of the box as described in Patent Document 1, the structure of the packing container including the box becomes complicated. This is not preferable because it may lead to an increase in 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 capable of preventing contamination of the glass rolls while having a simple structure.

The solution of 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 core in a state in which both sides in the axial direction of the core are exposed, and both sides of the core in the axial direction. A glass roll package having a pair of support parts and a box for accommodating the glass roll supported by the pair of support parts, wherein the entire glass roll is covered with a bag. , the glass roll is supported by a pair of support portions.

As described above, in the package according to the present invention, the entire glass roll is covered with the bag while being housed in the box. The glass film can be protected from the outside air by covering the entire glass film wound into a shape with a bag. As a result, it is possible to prevent the glass film from being exposed to the outside air more easily than in the prior art, and thus preventing foreign matter from adhering to the glass film. Of course, since it is sufficient to prepare only the bag, the glass film can be protected from the outside air at a lower cost than, for example, processing the box into a closed structure.

Further, in the package 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 as described above. By stepping on the glass roll, the glass roll can be easily loaded into the box and packed. That is, at the same time as the entire glass roll is housed in a bag previously installed inside the box, both sides in the axial direction of the winding core are placed on a pair of support portions. Then, the bag body is closed. As a result, the glass roll is accommodated in the box, and the entire glass roll is covered with the bag and supported by the pair of support portions. As described above, according to the present invention, the glass roll can be loaded into the box body and packed with relatively few man-hours. Moreover, when taking out the glass roll, it is sufficient to open the box and take out the glass roll together with the winding core, so that the glass roll can be easily taken out from the box.

Moreover, in the glass roll package according to the present invention, the bag may have an opening at one location.

Thus, by providing a bag having an opening at one place, it is only necessary to close the one place after the entire glass roll including the winding core is accommodated inside the bag through the opening. , the entire glass roll can be easily covered with the bag.

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

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

Moreover, in the glass roll package according to the present invention, when the glass roll package has the above-described flanges, the bag body may cover both the entire glass roll and the flanges.

By covering not only the glass roll composed 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. and the bag can form a certain space. As a result, it is possible to reliably prevent the glass film from being contaminated or damaged due to unnecessary contact between the bag and the glass roll.

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

By setting the gap between the flange and the supporting portion in this way, even if the glass roll is displaced 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 the one axial side portion from falling from the one supporting portion.

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

In this way, by adopting a structure in which the support section is divided into upper and lower parts, the winding core of the glass roll can be easily placed on the support section or detached from the support section. Further, at this time, the divided upper support portion is rotatably supported around a predetermined rotation axis, so that the upper support portion can be easily moved between the core support position and the retracted position. can be As a result, when the glass roll is loaded, the upper support is first retracted from the upper space of the lower support (that is, the support position of the winding core), and after the glass roll is placed, the upper support is rotated by a predetermined amount. It is rotated around the axis and brought into contact with 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 clamped and fixed between the upper and lower support portions. When the glass roll is to be taken out, 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 shaft and withdrawing it from the upper space of the lower support part. can. As described above, according to the supporting portion having the above configuration, it is possible to efficiently load or unload the glass rolls.

Further, in the glass roll package according to the present invention, the box may have a frame and a plurality of plate-like bodies which form the outer walls of the box and are detachably attached to the frame.

In this way, the plate-like body forming the outer wall of the box is detachably attached to the frame of the box, thereby improving the accessibility to the glass roll housed in the box. can be done. That is, by removing the plate-shaped body, the core supported by the support provided on the frame can be accessed from the side of the box, so that the core can be easily lifted and the glass roll can be opened. can be taken out. Of course, when loading the glass roll, it is possible to easily load the glass roll inside the box body by placing the core of the glass roll on the support while removing the plate-shaped body located outside the support. can be accommodated in

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

In this way, if the pair of support portions are formed by a part of the frame, the box can be simplified further, contributing to compactness. Further, by providing an insertion portion into which the plate-like body can be inserted outside the supporting portion of the frame, the plate-like body can be easily attached to and detached from the frame. Thereby, the workability of loading or unloading the glass roll can be further improved.

Moreover, the solution of the above problems is also achieved by a 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 into a roll shape around the winding core in a state where both axial side portions of the winding core are exposed, and a step of manufacturing a glass roll. A step of installing a bag inside a box having a pair of support portions for supporting the core, and housing the entire glass roll including both sides of the core in the axial direction inside the bag. It is characterized by having a step of placing both directional side portions on a pair of supporting portions and a step of closing the bag body.

As described above, according to the method of manufacturing the package according to the present invention, the whole glass film wound in a roll shape is wrapped in the bag just by housing the glass roll inside the bag, as in the case of the package described above. In the covered state, the glass film can be protected from the outside air. As a result, it is possible to prevent the glass film from being exposed to the outside air more easily than in the prior art, and thus preventing foreign matter from adhering to the glass film. Of course, since it is sufficient to prepare only the bag, the glass film can be protected from the outside air at a lower cost than, for example, processing the box into a closed structure. At the same time that the entire glass roll is housed in a bag that has been placed inside the box in advance, both sides of the winding core in the axial direction are placed on a pair of support portions, and then the bag is placed. By closing the opening, the glass roll is accommodated in the box, and the entire glass roll is covered with the bag and supported by the pair of support portions. Therefore, according to the present invention, it is possible to load the glass roll into the box body and pack it with a relatively small number of man-hours. Moreover, when taking out the glass roll, it is sufficient to open the box and take out the glass roll together with the winding core, so that the glass roll can be easily taken out from the box.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 10. FIG.

1 is an exploded perspective view of a glass roll package 10 according to this 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. is. As shown in these figures, this glass roll package 10 has a glass roll 11 and a pair of support portions 12, 12 for supporting the glass roll 11, a box 13 for accommodating the glass roll 11, and a glass roll. A bag body 14 covering the entire roll 11 is provided. Moreover, in this embodiment, the glass roll package 10 further includes a pair of flanges 15 , 15 attached to the glass roll 11 .

Here, the glass roll 11 to be packed is, as shown in FIG. , the glass film G and the buffer sheet 17 are superimposed and wound into a roll.

The winding core 16 has a hollow cylindrical shape with a hole 16a, as shown in FIG. 4, for example. Both sides 16b, 16b in the axial direction of the winding core 16 are exposed portions when the glass film G is wound into a roll. It corresponds to the part which protrudes in the width direction of the glass film G rather than both end surfaces. The winding core 16 is not limited to the hollow cylindrical shape according to the illustrated example, and may be, for example, a solid columnar shape.

Any material can be used for the winding core 16 as long as there is no problem in terms of strength. Resin, thermosetting resin such as polyurethane, diallyl terephthalate resin, thermoplastic resin such as polyethylene, polypropylene, polystyrene, AS resin, ABS resin, methacrylic resin, vinyl chloride, or glass to these thermosetting resins or thermoplastic resins Reinforced plastics containing a reinforcing material such as fiber or carbon fiber, paper, or the like can be used as the material of the winding core 16 .

The glass film G is formed, for example, by an overflow down-draw method, and has a thickness within 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 dimension 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 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 still more preferably 1000 mm or more. Since the glass film G is used in a wide variety of devices, from small screen displays such as those for small mobile phones to large screen displays such as large television receivers, the width dimension of the glass film G is Ultimately, it is preferable to select an appropriate size 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 alkali-free glass is preferably used depending on the application. This is because when the glass film G contains an alkali 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 bent, it deteriorates over time. This is because there is a possibility that damage may occur from the structurally rough portion due to the Further, if the glass film G contains an alkali component, the properties of the thin film formed on the surface may be impaired when the glass film G is used for a glass substrate. The term "alkali-free glass" as used herein refers to glass that does not substantially contain alkali components. below).

From the viewpoint of protecting the glass film G, the buffer sheet 17 is wound around the winding core 16 in a state of being overlapped with the glass film G. It is interposed between the films G. At this time, the buffer 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, when the winding of the glass film G on the winding core 16 is completed, the buffer sheets 17 should be positioned on the innermost and outermost sides of the roll portion 11a. is preferred. Moreover, from the same point of view, it is preferable that the buffer sheet 17 protrudes from both widthwise end faces of the glass film G. As shown in FIG. Of course, both width direction end surfaces of the buffer sheet 17 and the width direction end surfaces of the glass film G may be aligned at the same width direction position, or the glass film G may be cut from the width direction end surfaces of the buffer sheet 17. You can put it out.

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

In principle, the material of the buffer sheet 17 is arbitrary, and interleaving paper, non-woven fabric, etc., 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 made of resin such as vinyl alcohol copolymer, ethylene-methacrylic acid copolymer, nylon (polyamide), polyimide, and cellophane can be applied. From the viewpoint of simultaneously securing cushioning performance and strength, it is preferable to use a foamed resin sheet made of foamed resin such as polyethylene as the cushioning sheet 17 . Moreover, from the viewpoint of improving slipperiness with the glass film G, it is preferable to use a resin sheet formed by dispersing silica or the like in the resin described above as the buffer sheet 17 . In this case, slippage of the glass film G and the buffer sheet 17 can be absorbed by the slipperiness of the resin sheet.

Further, in this embodiment, a pair of flanges 15 , 15 are attached to the winding core 16 of the glass roll 11 . These flanges 15, 15 are attached to both sides 16b, 16b in the axial direction of the winding core 16, and face the widthwise end faces of the glass film G over the entire area (see FIG. 2). That is, the outer diameter dimension of the flange 15 is larger than the outer diameter dimension of the roll portion 11 a formed by winding the glass film G around the winding core 16 . Moreover, in this embodiment, each flange 15 is opposed to the width direction edge surface of the glass film G in the width direction through a predetermined clearance.

Each flange 15 can be, for example, a disk-shaped integral piece, but in this embodiment, as shown in FIG. be done. In this case, the axial side portions 16b, 16b of the winding core 16 are sandwiched between the first and second division plates 15a, 15a and 15b, 15b of the flanges 15, respectively, and the first division plate 15a and the second division plate 15b are separated from each other. A pair of disk-shaped flanges 15, 15 as a whole are fixed to the outer circumference of the winding core 16 by connecting the two-part plate 15b by, for example, bolting.

In the present embodiment, the outer peripheral surface of the winding core 16 has a constant outer diameter for the purpose of reducing processing costs. For example, although not shown, a step may be provided on the outer periphery of the winding core 16, and the flange 15 may be brought into contact with this step in the axial direction.

The box 13 has a substantially rectangular parallelepiped shape as a whole. (see Figure 1). In this case, the glass roll 11 and the bag 14 are housed inside the box 13 . A pair of support portions 12 , 12 are provided on the frame 18 , and the glass roll 11 accommodated inside the box 13 is supported by the pair of support portions 12 , 12 .

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

Here, as shown in FIG. 3, each support portion 12 in this embodiment is divided into upper and lower portions, a lower support portion 20 supporting the lower side of the outer peripheral surface of each axial side portion 16b, and a and 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 18 . (that is, the support position of the winding core 16 shown in FIG. 3) and a retracted position away from the support position (see FIG. 1).

In this embodiment, the lower support part 20 is formed by deforming a portion of the frame 18, and the support surface 20a of the lower support part 20 is a pair of slopes that approach each other downward. formed (see FIG. 3). In this embodiment, the upper support portion 21 has a substantially semi-annular curved portion that is separate from the frame 18, and the support surface 21a of the upper support portion 21 has a semi-annular curved portion. is formed on the inner peripheral surface of In this case, when 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 vertically. It can be clamped (see FIG. 3).

Further, when a pair of flanges 15, 15 are attached to the winding core 16 of the glass roll 11, contact between the flange 15 and the support portion 12 (here, the lower support portion 20) causes movement of the glass roll 11 in the width direction. A gap g1 between each flange 15 and the frame 18 is set to a predetermined size or less so as to prevent 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 gap g1, the gap g1 is set 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 be less than or equal 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 13, it is preferable to set the gaps g1 and g2 to a certain size from the viewpoint of loading. .

Further, in this embodiment, an insertion portion 23 into which the plate-like body 19 can be inserted is provided outside the support portion 12 of the frame 18 (see FIGS. 1 to 3). The insertion part 23 has a groove shape, for example, and is fitted with the bottom side 19a and the pair of side sides 19b, 19b of the inserted plate-like body 19. As shown in FIG. Of course, the insertion direction of the plate-like body 19 is not limited downward. For example, although not shown, the inserting portion 23 may be configured such that the vertically oriented plate-like body 19 is slid horizontally to be set at a position forming the outer wall of the box 18 .

In this embodiment, the bag body 14 has an opening 24 at one location, and as shown in FIG. It is said that The opening 24 is large enough to allow the glass roll 11 with the pair of flanges 15 attached to both sides 16b of the winding core 16 in the axial direction to pass therethrough. At this time, as shown in FIG. 1, the size and shape of the opening 24 are such that the glass roll 11 can be inserted with the width direction of the glass roll 11 (longitudinal direction of the winding core 16) being substantially horizontal. should be set.

As shown in FIGS. 2 and 3, the bag body 14 configured as described above accommodates the entire glass roll 11 including both sides 16b, 16b of the winding core 16 in the axial direction. In this embodiment, the entire glass roll 11 further including the pair of flanges 15 , 15 is housed inside the bag 14 . In this case, the opening 24 (see FIG. 1) of the bag body 14 is closed above the glass roll 11. A portion 25 is formed. In this case, the flange 15 and the bag body 14 may be in contact with each other, or may be positively contacted to partially stretch the bag body 14 so that the bag body 14 and the roll portion 11a of the glass roll 11 are stretched. (See Fig. 5).

In the present embodiment, the box body 13 containing the glass roll 11, the pair of support parts 12, 12, the bag body 14, and the pair of flanges 15, 15 further has a lid part 26 (Fig. 1). Fitting concave portions 26a that are open downward are provided at the four corners of the lid portion 26. By fitting with fitting convex portions 18a that protrude upward from the four corners of the frame body 18, the lid portion 26 is formed into a box shape. 13 is closed.

An example of a method of manufacturing the glass roll package 10 having the above configuration, in other words, an example of a method of loading the glass roll 11 into the box 13 will be described below with reference to FIGS. 6 to 10. FIG.

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

For example, as shown in FIG. 4, a long glass film G is wound around a core 16 together with a buffer sheet 17, and a pair of flanges 15, 15 are provided on both sides 16b, 16b of the core 16 in the axial direction. 15 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 axial side portions 16b, 16b of the winding core 16 are placed on the pair of support portions 12, 12 via the bag body 14 (the state shown in FIG. 5). , 16b is introduced into the bag body 14 .

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

In this embodiment, as described above, after the entire glass roll 11 is housed inside the bag 14 and the opening portion 24 is closed, the upper support portion 21 is rotated around the rotation shaft 22 so that the lower side is opened. Move it above the support 20 (see FIG. 3). By fixing the upper support portion 21 to the lower support portion 20 by bolting or the like, both axial side portions 16b, 16b of the winding core 16 are sandwiched. As a result, the axial side portions 16b, 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. 21a (see FIG. 9).

After that, the four plate-like bodies 19 are inserted into the inserting portions 23 of the frame body 18 from above downward. As a result, the four sides of the glass roll 11 are covered with the plates 19 (see FIG. 10).

Finally, the glass roll package 10 is completed by fitting the lid portion 26 onto the upper portion of the frame 18 .

As described above, according to the glass roll package 10 according to the present invention, the entire glass roll 11 including the axial side portions 16b, 16b of the winding core 16 is packed in the box 13. It becomes a form covered with 14. Therefore, only by housing the glass roll 11 inside the bag body 14, the whole glass film G wound in 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 more easily prevent the glass film G from being exposed to the outside air, and by extension, from attaching foreign matter to the glass film G, more easily than before. Of course, it is only necessary to prepare the bag 14, so that the glass film G can be protected from the outside air at a lower cost than, for example, processing the box 13 into a closed structure.

Further, in the manufacturing method of the package of the glass roll 11 according to the present embodiment, the entire glass roll 11 is housed inside the bag 14 which is placed inside the box 13 in advance with the opening 24 facing upward. At the same time, both axial side portions 16b, 16b of the winding core 16 are placed on the pair of support portions 12, 12. As shown in FIG. Then, the opening 24 of the bag 14 is closed. As a result, the glass roll 11 is housed in the box 13, and the entire glass roll 11 is covered with the bag 14 and supported by the pair of support portions 12, 12. As shown in FIG. Therefore, according to the manufacturing method of this package, it becomes possible to load and package the glass roll 11 inside the box 13 with a small number of man-hours. When taking out the glass roll 11, it is enough to open the box 13 and take out the glass roll 11 together with the winding core 16 regardless of whether the bag 14 is open or closed. 13 can be easily taken out.

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

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

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

Although one embodiment of the present invention has been described above, the glass roll package and the method for manufacturing the same according to the present invention are not limited to the above-described embodiments, and may take various forms within the scope of the present invention. Is possible.

For example, in the above-described embodiment, the bag body 14 having the opening 24 at one place is arranged in the box body 13, but a bag body 14 having an opening other than this may be employed. is also possible. For example, although not shown, a bag having two or more openings 24 may be employed. In addition, 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 side seal type, pillow type (a single film is sealed back to back to form a cylinder, A bag body 14 having a known form such as a type in which one opening is sealed, a gusset type, or the like can also be employed. Alternatively, even a sheet-like body can be used as the bag body 14 depending on its 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 as to cover the entire glass roll 11 . In the above embodiment, the bag 14 is placed inside the box 13 with the opening 24 facing upward in advance, and the glass roll 11 is introduced from above to cover the entire glass roll 11 with the bag 14 . Although the case of covering is exemplified, it is also possible to adopt a mode other than this. For example, the entire glass roll 11 may be housed inside the bag 14 in advance, and then housed inside the box 13 . Moreover, in this case, after the opening 24 of the bag body 14 is closed first, the bag body 14 may be housed inside the box body 13 . In short, in a state in which the entire glass roll 11 including the axial side portions 16b, 16b of the winding core 16 is covered with the bag body 14, the axial side portions 16b, 16b of the winding core 16 are supported by the pair of support portions 12, 12. The form of the bag 14 and the form in which the glass roll 11 is accommodated by the bag 14 are arbitrary as long as the glass roll 11 is supported by the .

In the above embodiment, the support surface 20a of the lower support part 20 is formed of a pair of slopes that approach each other downward (see FIG. 3). , it is also possible to adopt a form other than the above. Further, at that time, it does not matter whether the outer peripheral surface of the axial side portion 16b of the winding core 16 is in point contact or surface contact. 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 similarly take any form. For example, the support surface 21a of the upper support portion 12 may be formed of a pair of slopes, like the support surface 20a of the lower support portion.

In the above-described embodiment, the axial side portion 16b of the winding core 16 is fixed by being sandwiched from above and below by the lower support portion 20 and the upper support portion 21, which are divided vertically. is not limited. For example, although illustration is omitted, if the upward floating of the glass roll 11 is regulated by a structure other than the support part 12, only the lower support part 20 that supports the lower side of the outer peripheral surface of the winding core 16 is used as the support part. 12 may be configured.

Moreover, in the above-described embodiment, the axial side portions 16b, 16b of the winding core 16 are directly supported by the pair of support portions 12, 12, but the present invention is not limited to this form. The present invention also includes a configuration in which axially opposite side portions 16 b , 16 b of the winding core 16 are supported by a pair of support portions 12 , 12 via flanges 15 .
