Description

Glass roll package and manufacturing method thereof

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 the request, development of a so-called glass film whose thickness has been reduced to a film shape has been advanced. For example, a glass film having a thickness of 200 μm or less has been developed.

Also, as a packaging form of this glass film, it is being promoted to adopt a glass roll in which the glass film is wound around a winding core in a roll shape. Such a packing form pays attention to the flexibility of a glass film, and since it has various advantages, such as space saving, attracts attention as a packing form suitable for a glass film.

By the way, since this kind of glass product (glass film) requires high surface quality (for example, cleanliness) according to a use, when packing and conveying the glass film mentioned above in the form of a glass roll. It is necessary to prevent a situation that causes contamination of the glass roll such as adhesion of foreign substances and corrosion.

Here, for example, in Patent Document 1, as a packaging container for glass rolls, a box body in which a storage chamber in which a glass roll is stored is formed, and a lid member that is attached to an opening of the box body and seals the storage chamber And a humidity adjusting unit that adjusts 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.

JP 2014-80203 A

In this way, with the packaging container described in Patent Document 1, since the storage chamber of the glass roll provided inside the box can be hermetically sealed, intrusion of outside air, and thus foreign substances that enter the inside of the box together with outside air can be achieved. It seems that the adhesion to the glass film can be effectively prevented. However, if the inside of the box is to be sealed as described in Patent Document 1, the structure of the packaging container including the box is complicated. This is not preferable because there is a risk of increasing 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 capable of preventing contamination of a glass roll with a simple configuration.

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

Thus, in the packaging body according to the present invention, since the entire glass roll is covered with the bag body in the state of being accommodated in the box body, the roll is simply accommodated inside the bag body. The glass film can be protected from the outside air in a state where the entire glass film wound in a shape is covered with a bag. As a result, it is possible to prevent a situation in which outside air is exposed to the glass film more easily than before, and a situation in which foreign matter adheres. Of course, since only a bag body needs to be prepared, the glass film can be protected from the outside air at a lower cost than, for example, processing the box body into a sealed structure.

Further, in the package according to the present invention, the glass roll is supported by the pair of support portions in the state where the entire glass roll is covered with the bag as described above. By stepping on, the glass roll can be easily loaded and packed inside the box. In other words, the entire glass roll is housed in a bag body that is previously set inside the box, and at the same time, both axial sides of the winding core are placed on the pair of support portions. Then, the bag body is closed. Thereby, while a glass roll is accommodated in a box, it will be in the state supported by a pair of support part in the state where the whole glass roll was covered with the bag. As described above, according to the present invention, the glass roll can be loaded and packed inside the box with a relatively small number of steps. Further, when the glass roll is taken out, 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.

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

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

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 in the axial direction of the winding core. May be. In addition, the width direction here shall mean the direction along the winding center of a glass film.

Thus, by providing flanges on both sides in the axial direction of the winding core, for example, when the entire glass roll has moved in the width direction, the situation in which the end surface in the width direction of the glass film is in contact with the box is reliably avoided, Breakage of the end face can be reliably prevented.

Moreover, when it has the flange of the said structure, in the glass roll package which concerns on this invention, the bag body may cover both the whole glass roll and a flange.

By covering not only the glass roll consisting of the winding core and the glass film but also all flanges 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 body and the bag body. This makes it 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 flange and the support portion are prevented from falling from any 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.

By setting the gap between the flange and the support portion in this way, even if the glass roll is displaced in the width direction during conveyance, the flange regulates the movement in the width direction of the glass roll at a predetermined position. It is possible to reliably prevent the situation where one axial side portion falls from one support 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 core, and an upper support part that supports the upper side of the outer peripheral surface of the core. The upper support part may be movable between a support position of the winding core and a retracted position away from the support position by being supported so as to be rotatable about a predetermined rotation axis.

Thus, by adopting a structure in which the support portion is divided vertically, the winding core of the glass roll can be easily placed on or removed from the support portion. 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. It can be. Accordingly, when the glass roll is loaded, the upper support portion is first retracted from the upper space of 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 by a predetermined amount. It is rotated around the axis and brought into contact with the upper outer peripheral surface of the winding core. Thereafter, by fixing the upper support portion to the lower support portion, the winding core can be easily held and fixed by the upper and lower support portions. Also, when taking out the glass roll, it is possible to lift the glass roll upward and take it out from the box body by simply rotating the upper support portion around the rotation axis and retracting it from the upper space of the lower support portion. it can. As mentioned above, according to the support part of the said structure, it becomes possible to load or take out a glass roll efficiently.

Moreover, in the glass roll package according to the present invention, the box may include a frame and a plurality of plate-like bodies that are detachably attached to the frame by forming the outer wall of the box.

Thus, the accessibility to the glass roll in the state accommodated in the box is improved by adopting a structure in which the plate-like body forming the outer wall of the box is detachably attached to the frame of the box. Can do. That is, by removing the plate-like body, it is possible to access the winding core in a state supported by the support portion provided on the frame body from the side of the box body. Can be taken out. Of course, when the glass roll is loaded, the glass roll can be easily placed inside the box by placing the roll core of the glass roll on the support part with the plate-like body positioned outside the support part removed. Can be accommodated.

Further, in the case where the box includes a frame and a plurality of plate-like bodies, in the glass roll package according to the present invention, a pair of support portions are configured by a part of the frame, and the frame body The insertion part which can insert a plate-shaped object may be provided in the outer side rather than the support part.

As described above, if the pair of support portions are formed by a part of the frame body, the box body can be further simplified, which contributes to compactness. Moreover, the plate-like body can be easily attached to and detached from the frame body by providing an insertion portion into which the plate-like body can be inserted outside the support portion of the frame body. Thereby, workability | operativity which concerns on loading or taking out of a glass roll can further be improved.

Moreover, the solution of the above-mentioned problem is also achieved by the method for producing a glass roll package according to the present invention. That is, this production method includes a step of winding a glass film around a winding core in a roll shape with both axial sides of the winding core exposed to produce a glass roll, and both axial sides of the winding core. A step of installing the bag body inside the box body having a pair of support portions for supporting the wire core, and the entire glass roll including both axial sides of the core core inside the bag body, It is characterized by the point provided with the process of mounting a directional both side part on a pair of support part, and the process of closing a bag.

As described above, according to the method for producing a package according to the present invention, as in the package described above, the entire glass film wound up in a roll shape can be obtained by simply storing the glass roll in the bag. As the covered state, the glass film can be protected from the outside air. As a result, it is possible to prevent a situation in which outside air is exposed to the glass film more easily than before, and a situation in which foreign matter adheres. Of course, since only a bag body needs to be prepared, the glass film can be protected from the outside air at a lower cost than, for example, processing the box body into a sealed structure. In addition, the entire glass roll is accommodated inside the bag body that has been previously installed inside the box body, and at the same time, both sides in the axial direction of the winding core are placed on the pair of support portions, and then the bag body is mounted. By closing the mouth, the glass roll is accommodated in the box, and the entire glass roll is supported by the pair of support portions in a state of being covered with the bag. Therefore, according to the present invention, the glass roll can be loaded and packed inside the box with a relatively small number of steps. Further, when the glass roll is taken out, 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.

As described above, according to the present invention, it is possible to produce a glass roll package that can prevent contamination of a glass roll with a simple configuration.

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

FIG. 1 is an exploded perspective view of the glass roll package 10 according to 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. It is. As shown in these drawings, the glass roll package 10 includes a glass roll 11, a pair of

support portions

12 and 12 that support the glass roll 11, a box 13 that accommodates the glass roll 11, and a glass A bag 14 covering the entire roll 11. 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, the glass roll 11 to be packaged is formed by winding a long glass film G around the core 16 as shown in FIG. 4. In this embodiment, the glass roll 11 is formed on the outer peripheral surface of the core 16. The glass film G and the buffer sheet 17 are in a state of being wound up in a roll shape.

For example, as shown in FIG. 4, the winding core 16 has a hollow cylindrical shape having a hole 16a. Moreover, the axial direction both

side parts

16b and 16b of the winding core 16 are exposed parts in the state which wound the glass film G in roll shape, and if the view is changed, the width direction of the glass film G wound up in roll shape It corresponds to a portion protruding in the width direction of the glass film G 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 columnar shape.

The material of the winding core 16 is arbitrary as long as there is no problem in strength. For example, metals such as aluminum alloy, stainless steel, manganese steel, carbon steel, phenol resin, urea resin, melamine resin, unsaturated polyester resin, epoxy Thermosetting resins such as resin, polyurethane, diallyl terephthalate resin, thermoplastic resins such as polyethylene, polypropylene, polystyrene, AS resin, ABS resin, methacrylic resin, vinyl chloride, or glass for these thermosetting resins and thermoplastic resins Reinforced plastics, paper, and the like obtained by blending reinforcing materials such as fibers and carbon fibers can be used as the material of the winding core 16.

The glass film G is formed by, for example, an overflow downdraw method, and has a thickness dimension set in a range of 1 μm to 200 μm (preferably 10 μm to 100 μm). The reason why the thickness is set to such a thickness is that if the thickness dimension is within the numerical range, moderate flexibility and strength can be imparted to the glass film G, and there is no hindrance during winding. It is.

The width direction dimension of the glass film G is set to, for example, 100 mm or more, preferably set to 300 mm or more, more preferably set to 500 mm or more, and further preferably set to 1000 mm or more. In addition, since the glass film G is used for a wide variety of devices ranging from a small screen display for a small mobile phone to a large screen display such as a large television receiver, the width dimension of the glass film G is Ultimately, it is preferable to select appropriately 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 silicate glass such as silica glass and borosilicate glass can be used, but it is preferable to use alkali-free glass depending on the application. This is because, when an alkali component is contained in the glass film G, a phenomenon called soda blowing occurs, a part of the glass film G becomes structurally rough, and the glass film G is bent over time. This is because there is a possibility that damage may occur from the portion roughened by the structure. Moreover, when the glass film G contains an alkali component, the thin film characteristics formed on the surface may be impaired when the glass film G is used for a glass substrate. The alkali-free glass referred to here is a glass that does not substantially contain an alkali component. 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 buffer sheet 17 is wound around the winding core 16 in a state of being overlapped with the glass film G, and in a state where the winding is completed (the state shown in FIG. 1 and FIG. 4) It is interposed between the films G. At this time, the buffer sheet 17 is disposed 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. In addition, from the viewpoint of protecting the glass film G, the buffer 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 on the winding core 16 is completed. Is preferred. Further, from the same viewpoint, it is preferable that the buffer sheet 17 protrudes from both end surfaces in the width direction of the glass film G. Of course, both end surfaces in the width direction of the buffer sheet 17 and both end surfaces 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 surfaces in the width direction of the buffer sheet 17. It may be out.

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

The material of the buffer sheet 17 is in principle arbitrary, and for example, slip sheets or non-woven fabrics 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 vinyl alcohol copolymer, ethylene-methacrylic acid copolymer, nylon (polyamide), polyimide, cellophane, or the like is applicable. In addition, it is preferable to use the foamed resin sheet formed with foamed resin, such as polyethylene, as the buffer sheet 17 from a viewpoint of ensuring buffer performance and intensity | strength simultaneously. Further, from the viewpoint of improving the slipperiness with the glass film G, it is preferable to use a resin sheet formed by dispersing silica or the like in the above-described resin as the buffer sheet 17. In this case, the slip which arises between the glass film G and the buffer sheet 17 can be absorbed by the slipperiness of the resin sheet.

In this 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 the axial direction both

side parts

16b and 16b of the winding core 16, and are opposed to the end face of the glass film G in the width direction (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 has opposed the width direction end surface of the glass film G in the width direction via the predetermined clearance gap.

Each flange 15 may be a disc-like integrated product, for example, but in this embodiment, as shown in FIG. 4, it is composed of a first divided plate 15a and a second divided plate 15b that are both semi-disc shaped. Is done. In this case, the first divided plate 15a and the second divided plate 15a and the second divided

plates

15b and 15b are sandwiched between the first divided

plates

15a and 15b and the second divided

plates

15b and 15b, respectively. 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 by connecting the two divided plates 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 the processing cost, but the purpose is to accurately position the flange 15 relative to the winding core 16 in the axial direction. For example, although not illustrated, a step may be provided on the outer periphery of the winding core 16 and the flange 15 may be brought into contact with the step in the axial direction.

The box 13 has a substantially rectangular parallelepiped shape as a whole. In the present embodiment, the frame 18 and a plurality of plate-like bodies 19 that are detachably attached to the frame 18 and the outer wall of the box 13 are provided. (See FIG. 1). In this case, the glass roll 11 and the bag body 14 are accommodated inside the box body 13. In addition, a pair of

support portions

12, 12 are provided on the frame body 18, and the glass roll 11 accommodated inside the box body 13 is supported by the pair of

support portions

12, 12.

Specifically, the pair of

support portions

12 and 12 support the

axial side portions

16b and 16b of the winding core 16 as shown in FIG. At this time, both

side portions

16b and 16b in the axial direction of the winding core 16 are supported by the pair of

support portions

12 and 12 via the bag body 14, as shown in FIG.

Here, as shown in FIG. 3, each support part 12 is divided into upper and lower parts, and supports a lower support part 20 that supports the lower side of the outer peripheral surface of each axial side part 16b, and each axial side. And an upper support portion 21 that supports the upper outer peripheral surface of the portion 16b. Further, the upper support portion 21 is supported so as to be rotatable around a predetermined rotation shaft 22 disposed on the frame body 18, whereby the upper support portion 21 is positioned above the lower support portion 20. That is, it can be moved between a support position of the winding core 16 shown in FIG. 3 and a retracted position (see FIG. 1) away from the support position.

In the present embodiment, the lower support portion 20 is formed by deforming a part of the frame body 18, and the support surface 20 a of the lower support portion 20 is a pair of inclined surfaces that approach each other as going downward. Formed (see FIG. 3). Moreover, the upper side support part 21 has the substantially semi-circular curved part which makes a different body from the frame 18 in this embodiment, and the support surface 21a of the upper side support part 21 is a semi-annular curved part. It is formed by the inner peripheral surface. 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 viewed from above and below. It can be clamped (see FIG. 3).

Moreover, when a pair of

flanges

15 and 15 are attached to the winding core 16 of the glass roll 11, the contact of the flange 15 and the support part 12 (here lower support part 20) causes the glass roll 11 to move in the width direction. The gap g1 between each flange 15 and the frame body 18 is set to a predetermined size or less so as to prevent the support portion 12 from falling (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 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 below 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. In addition, since these gaps g1 and g2 function as play when the glass roll 11 is accommodated in the box 13, the gaps g1 and g2 are preferably set to a certain size from the viewpoint of loading ability. .

Further, in this embodiment, an insertion portion 23 capable of inserting the plate-like body 19 downward is provided outside the support portion 12 of the frame body 18 (see FIGS. 1 to 3). The insertion portion 23 has, for example, a groove shape, and is fitted to the bottom side 19a of the inserted plate-like body 19 and the pair of

side sides

19b and 19b. Of course, the insertion direction of the plate-like body 19 is not limited downward. For example, although not shown in the figure, the insertion portion 23 may be configured to be set at a position that forms the outer wall of the box 18 by sliding the plate-like body 19 in a vertical posture in the horizontal direction.

In this embodiment, the bag body 14 has an opening 24 at one place. As shown in FIG. 1, the bag body 14 can be disposed with the opening 24 facing upward when housed inside the box 13. It is said. Further, the opening 24 has a size that allows the glass roll 11 in a state in which the pair of

flanges

15 and 15 are attached to the both

axial sides

16 b and 16 b of the winding core 16 to be inserted. 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 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.

2 and 3, the bag body 14 having the above-described configuration accommodates the entire glass roll 11 including both

axial side portions

16b and 16b of the winding core 16. As shown in FIG. In the present embodiment, the entire glass roll 11 further including the pair of

flanges

15 and 15 is accommodated in the bag body 14. In this case, the opening 24 (see FIG. 1) of the bag body 14 is closed above the glass roll 11, in other words, the opening formed by closing the opening 24 above the glass roll 11. A portion 25 is formed. Further, in this case, the flange 15 and the bag body 14 may be in contact with each other, or the bag body 14 is partially stretched by positive contact, so that the bag body 14 and the roll portion 11a of the glass roll 11 are provided. The distance with the outer peripheral surface of the is secured (see FIG. 5).

The box body 13 that accommodates the glass roll 11, the pair of

support portions

12 and 12, the bag body 14, and the pair of

flanges

15 and 15 having the above configuration further includes a lid portion 26 in the present embodiment (see FIG. 1). Fitting recesses 26a that open downward are provided at the four corners of the lid 26, and the lid 26 is box-shaped by fitting with the fitting convexes 18a that protrude upward from the four corners of the frame 18. 13 is closed.

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

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 time (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 to be described later into the bag body 14, as shown in FIG. 6, the edge 24 a of the opening 24 may be installed in the folded state.

For example, as shown in FIG. 4, a long glass film G is wound around the winding core 16 together with the buffer sheet 17, and a pair of flanges 15 are provided on both

axial sides

16 b and 16 b of the winding core 16. The glass roll 11 to which 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, both

axial sides

16b, 16b of the winding core 16 are placed on the pair of

support portions

12, 12 via the bag body 14 (state shown in FIG. 5). , 16 b including the entire glass roll 11 is introduced into the bag body 14.

Thus, after the glass roll 11 is introduced into the bag body 14, 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

opposite sides

16 b and 16 b of the winding core 16 and the pair of

flanges

15 and 15 is covered with the bag body 14 and is cut off (sealed) from the outside air. It becomes a state. 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, after the entire glass roll 11 is accommodated in the bag body 14 and the opening 24 is closed, the upper support portion 21 is rotated around the rotation shaft 22, and the lower side It moves above the support part 20 (refer FIG. 3). And the upper side support part 21 is fixed to the lower side support part 20 by bolting etc., and the axial direction both

sides

16b and 16b of the winding core 16 are clamped. As a result, both

side portions

16b, 16b in the axial direction 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 via the bag body 14. It will be in the state supported by 21a (refer FIG. 9).

After that, the four plate-like bodies 19 are inserted into the insertion portion 23 of the frame body 18 from the upper side to the lower side. Thereby, the four directions of the glass roll 11 will be in the state covered with the plate-shaped body 19 (refer FIG. 10).

Finally, the glass roll package 10 is completed by fitting the lid portion 26 into 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 and 16b of the winding core 16 in the state accommodated in the box 13 is the bag. 14 is covered. Therefore, only by accommodating the glass roll 11 inside the bag body 14, the entire glass film G wound up 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 situation in which the outside air is exposed to the glass film G, and the situation in which foreign matter adheres, than ever before. Of course, since only the bag 14 needs to be prepared, the glass film G can be protected from the outside air at a lower cost than, for example, processing the box 13 into a sealed structure.

Moreover, in the manufacturing method of the package body of the glass roll 11 which concerns on this embodiment, the glass roll 11 whole is accommodated in the inside of the bag body 14 previously installed in the inside of the box body 13 with the opening part 24 facing upwards. At the same time, the axially

opposite 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. Thereby, while the glass roll 11 is accommodated in the box 13, it can be set as the state supported by the pair of

support parts

12 and 12 in the state covered with the bag body 14 whole. Therefore, according to the manufacturing method of this packing body, it becomes possible to load and pack the glass roll 11 inside the box body 13 with few man-hours. Further, when the glass roll 11 is taken out, it is only necessary to open the box 13 and take out the glass roll 11 together with the winding core 16 in a state where the bag body 14 is opened or closed. 13 can be easily taken out.

Moreover, in this embodiment, the bag body 14 which has the opening part 24 in one place was used (refer FIG. 1). If there is only one opening 24, the entire glass roll 11 is accommodated inside the bag body 14, and then it is only necessary to close one place, so that the operation 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 around the winding core 16 and closing the opening, so that work is easy. In particular, as in this embodiment, by providing the lid portion 26 above the box body 13 and the closing 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 26 can be removed, and the bag body 14 can be opened immediately from above.

When the box 13 has a frame 18 and a plurality of plate-like bodies 19 that are detachably attached to the frame 18 as an outer wall of the box 13 as in the present embodiment, the box Accessibility to the glass roll 11 accommodated in the state 13 can be enhanced. That is, by removing the lid 26 and removing the plate-like body 19, the core 16 in a state of being supported by the

support parts

12, 12 provided on the frame body 18 can be 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 13 and the bag 14.

Further, in the present embodiment, a pair of

flanges

15 and 15 that are opposed to the entire width direction end surface of the glass film G through a predetermined gap are attached to the axial direction both

side portions

16b and 16b of the winding core 16. Therefore, for example, even if the entire glass roll 11 moves in the width direction, it is possible to reliably avoid the situation in which the end surface in the width direction of the glass film G comes into contact with the support portion 12 and reliably prevent the end surface from being damaged. it can. At this time, the bag body 14 covers both the entire glass roll 11 and the pair of

flanges

15 and 15, whereby the flange 15 regulates the movement of the bag body 14 to the roll part 11a, and the roll part 11a A certain space can be formed between the outer peripheral surface and the bag body 14 (see FIG. 5). Thereby, it becomes 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.

As mentioned above, although one Embodiment of this invention was described, the glass roll package which concerns on this invention, and its manufacturing method are not limited to the said embodiment, Various forms are taken within the scope of the present invention. It is possible.

For example, in the said embodiment, although the case where what has the opening part 24 was arrange | positioned in the box 13 as the bag body 14 was illustrated, the bag body 14 which makes other opening forms is employ | adopted. Is also possible. For example, although illustration is omitted, a bag having two or more openings 24 may be employed. Moreover, the form of the bag body 14 having the opening 24 in 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 into a cylindrical shape, A bag body 14 having a known form such as a mold formed by sealing one opening) or a gusset type may be employed. Or even if it is a sheet-like body, it may become the 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. Moreover, in the said embodiment, the bag body 14 is arrange | positioned inside the box 13 with the opening part 24 facing upward beforehand, the glass roll 11 is introduce | transduced from upper direction, and the glass roll 11 whole is the bag body 14 Although the case where it covered is illustrated, it is also possible to take other modes. For example, it is possible to accommodate the entire glass roll 11 in the bag body 14 in the box body 13 in advance. In this case, the opening portion 24 of the bag body 14 may be closed first, and then accommodated in the box body 13. In short, in a state where the entire glass roll 11 including the axially

opposite sides

16b and 16b of the winding core 16 is covered with the bag 14, the axially

opposite sides

16b and 16b of the winding core 16 are a pair of

support portions

12 and 12. As long as it is supported, the form of the bag body 14 and the accommodation form of the glass roll 11 by the bag body 14 are arbitrary.

Moreover, in the said embodiment, although the support surface 20a of the lower side support part 20 illustrated the case where it forms with a pair of slope which approaches mutually as it goes below (refer FIG. 3), of course, the support surface 20a is It is also possible to adopt forms other than those described above. In this case, it does not matter whether the outer peripheral surface of the axial side portion 16b of the winding core 16 is 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, you may form the support surface 21a of the upper side support part 12 with a pair of inclined surface similarly to the support surface 20a of a lower side support part.

Moreover, in the said embodiment, although the case where the axial direction side part 16b of the winding core 16 was clamped from the upper and lower sides by the lower side support part 20 and the upper side support part 21 which were divided | segmented up and down was illustrated, of course, to this Is not limited. For example, although illustration is omitted, if the uplift of the glass roll 11 is restricted with a configuration other than the support portion 12, the support portion is only the lower support portion 20 that supports the lower side of the outer peripheral surface of the winding core 16. 12 may be configured.

Moreover, although the case where the axial direction both

sides

16b and 16b of the winding core 16 were directly supported by a pair of

support parts

12 and 12 was illustrated in the said embodiment, it is not limited to this form. The present invention also includes a form in which both

axial side portions

16 b and 16 b of the winding core 16 are supported by the pair of

support portions
