Description

  The present invention relates to a winding device that winds and holds a thin glass sheet in a roll shape, and a storage device that stores the winding device and uses it for conveyance or the like.

Currently, when manufacturing a liquid crystal panel used as a display device in a mobile terminal such as a small information terminal device or a mobile phone, a circuit for display is formed on a glass substrate having a thickness of 0.7 mm to configure the liquid crystal panel. Thereafter, the back side of the glass substrate is shaved by wet etching to reduce the thickness to about 0.3 mm.
However, in the future, this type of liquid crystal panel for display devices is expected to be manufactured using thin glass having a thickness of about 0.1 mm. If this thin glass sheet having a thickness of about 0.1 mm is used for a display device, it can be estimated that the manufacturing process of the display panel is renewed.

For example, since the thin glass having the above-mentioned thickness can be wound around the winding core in a roll shape, when a glass substrate is transported from a factory that manufactures glass to a factory that manufactures display panels, a single wafer that is currently mainstream It is no longer in the form of conveyance, and can be conveyed in roll form as a roll glass. Accordingly, in the display panel manufacturing factory, the thin glass that has been carried into the production line in the form of rolled glass is cut out to a desired size and is put into the production process of the display panel.
The roll glass described above has a structure in which a strip-shaped thin glass is wound around the outer peripheral surface of the winding core. However, the strength of the end surface of the thin glass is particularly weak, and scratches such as chipping and cracking occur with a slight impact. Therefore, in order to protect the end face of the thin glass, it is necessary to provide a flange on the winding core to protect the end of the thin glass.

  As a technique for winding this type of thin glass around a winding core in a roll shape, conventionally, a glass roll is formed by winding a glass film with a buffer sheet on a winding core, and the glass is wound on both ends in the width direction of the wound glass film. There is known a structure in which a flange is provided so as to be separated from the film, and a buffering means is disposed between the flange and an end in the width direction of the glass film. (See Patent Document 1)

Japanese Unexamined Patent Publication No. 2010-132348

  In the technique described in Patent Document 1 described above, the buffer sheet protrudes from the width direction end portion of the glass film to the portion between the width direction end portion and the flange of the glass film, and the protruding portion of the buffer sheet is used as a buffer means for glass. It is set as the structure which can protect the edge part of a glass film by arrange | positioning between a film and a flange, and can perform the winding-up operation | work and taking-out operation | work of a glass film smoothly.

  However, in the structure in which the buffer sheet protrudes from the portion between the width direction end of the glass film and the flange and uses it as a buffer means, there is a wide gap between the width direction end of the glass film and the flange. Therefore, the end face position of the glass film may be shifted due to shaking or impact during transportation, and the end portion of the glass film and the flange may collide, and the end face of the glass film may be wrinkled.

  The present invention has been made in view of the above circumstances, and is a winding device having a structure in which a thin glass is wound around a winding core, which eliminates the possibility of causing the thin glass to collide with the flange in the middle of conveyance, and may cause wrinkles on the thin glass.

“First Embodiment”
Hereinafter, a first embodiment of a winding device according to the present invention will be described with reference to the accompanying drawings, but the present invention is not limited to the embodiments described below.
FIG. 1 shows a cross-sectional structure of a winding device of a first embodiment according to the present invention. A winding device 1 of this embodiment includes a metal cylindrical winding core 2 and the length of the winding core 2. It consists mainly of metal donut disk-shaped flanges 3 and 3 that are attached to both ends in the vertical direction. Also, a roll glass 4 is formed by winding a thin glass sheet G together with a buffer sheet (buffer material) (not shown) at the center in the length direction of the winding core 2, and both ends of the roll body 4 in the length direction are the left and right flanges 3. 3 between.

Although the constituent material of the said winding core 2 and the flange 3 is not specifically limited, It consists of metal materials with high intensity | strength, such as stainless steel, manganese steel, carbon steel, or an aluminum alloy.
Since the winding core 2 winds and holds the strip-shaped thin glass G having a predetermined width, the winding core 2 needs to be strong enough not to be deformed by the winding pressure of the thin glass G, and its outer peripheral surface is in contact with the thin glass G by contact with the thin glass G. It is preferable that the surface is smoothed so as not to give a turbulence. As an example, if the thin glass G wound around the winding core 2 has a thickness of 100 μm (0.1 mm), a width of 1000 mm, and a length of about 400 m, the weight is about 100 kg, so that the roll body 4 having such a weight can be held. Strength is required for the core 2.
The flange 3 is mounted so as to be movable in the length direction of the core 2 by inserting the core 2 into the center hole 3a.

A winding region 2a having a width capable of winding a strip-shaped thin glass sheet G having a predetermined width is defined in the central portion of the winding core 2 in the length direction, and the thin glass sheets G are wound in multiple layers around the winding region 2a. The flange 3 is arrange | positioned at the width direction both ends. Further, a plurality of slit-like insertion holes 2 b including a position where the flange 3 is disposed and extending slightly outside the position are formed in the circumferential direction of the winding core 2 at a predetermined interval.
Locking bolts (locking tools) 5 are provided in the portions of the winding cores 2 where the insertion holes 2b are formed so as to penetrate the peripheral wall 2A of the winding core 2 in the thickness direction. Is extended to the outside of the core 2, and a nut 6 is screwed to the tip 5 b of the locking bolt 5 protruding inside the core 2.
Further, the locking bolt 5 is inserted in the outer periphery of the part where the insertion hole 2 b is formed in the winding core 2 and passes through the through hole portion 7 a penetrating in the radial direction of the locking ring 7. Is inserted. That is, in the example of FIG. 1, the locking bolt 5 is provided so as to pass through the through hole portion 7 a of the locking ring 7 and further pass through the insertion hole 2 b of the winding core 2, and pass through the peripheral wall 2 </ b> A of the winding core 2. ing. The locking bolt 5 presses the locking ring 7, the inner end of the locking ring 7 contacts the flange 3 to press the flange 3, the flange 3 is positioned, and the flange 3 presses the end surface of the roll body 4. Therefore, the locking bolt 5 and the locking ring 7 constitute a pressing unit and a locking unit for the flange 3.

The belt-shaped thin glass sheet G wound around the winding core 2 is wound by the required number of layers, and the outermost peripheral end portion thereof is prevented from coming off by a restraining plate 9 attached to the flange 3. The restraining plate 9 is a curved plate having a shape (tile shape) that matches the curved surface drawn by the outermost peripheral end portion of the thin glass G, and is installed on the left and right flanges 3 and 3. Specifically, a plurality of fitting holes 3b through which the deterrence plate 9 can be inserted are formed intermittently in the circumferential direction of the flange 3 in a portion near the outer peripheral edge of the inner surface of the flanges 3 and 3, The restraining plate 9 is disposed so as to pass through both end portions of the fitting holes 3b and 3b facing each other, and the restraining plate 9 presses the end of the outermost thin glass G.
Although the thin glass G has flexibility, since it rebounds by its own elastic force when it is wound around the core 2, the outer periphery of the core 2 is pressed by pressing the outer peripheral surface of the thin glass G with the suppression plate 9. In addition, the roll body 4 can be stably held.
It is desirable to affix a cushion layer made of a soft material on the back side of the suppression plate 9 so as not to be brazed to the thin glass G. Further, a plurality of suppression plates 9 may be arranged along the outer peripheral portions of the flanges 3 and 3 so that the outer peripheral surface of the roll body 4 is pressed at a plurality of locations.

  The left and right flanges 3 and 3 inserted through the winding core 2 press the roll body 4 made of the thin glass G so as to sandwich the left and right sides. That is, the left flange 3 of the winding core 2 is pressed against the left end surface of the roll body 4 with a predetermined pressure, and the right flange 3 of the winding core 2 is pressed against the right end surface of the roll body 4 with a predetermined pressure. Accordingly, the roll body 4 is prevented from coming off by the restraining plate 9 while being sandwiched between the flanges 3 and 3 at a predetermined pressure from both sides. Further, each flange 3 is fixed in a state in which movement along the length direction of the winding core 2 is prevented by a locking ring 7 in which a locking bolt 5 is fixed to the outer periphery of the winding core 2.

  The thin glass G has a thickness of 1 μm to 300 μm (preferably 10 μm to 300 μm) and has flexibility, so if the outer diameter of the winding core 2 is a size of several tens cm or more, a load is applied to the thin glass G. Winding is possible without applying. As an example, when a thin glass sheet G of 0.1 mm is applied, the outer diameter of the winding core 2 can be set to about 800 mm. In addition, if the thickness of the thin glass G is less than 1 μm, the strength becomes insufficient and the handling tends to be difficult, and if the thickness of the thin glass G exceeds 300 μm (0.3 mm), the flexibility becomes insufficient. Thus, the outer diameter of the core 2 must be made larger than the transportable size.

  The glass composition of the thin glass G is not particularly limited. Therefore, any of non-alkali glass, soda lime glass, mixed alkali glass, borosilicate glass, or other glass may be used. Moreover, the application of the thin glass G to be applied is not limited to a flat panel display, an architectural use, a vehicle use, or these uses, and includes various other uses.

In addition, as glass suitable for the thin glass G, the alkali free glass which has the following compositions can be used in the mass percentage display of an oxide basis.
_{SiO 2: 50~66%, Al 2} O 3: 10.5~24%, B 2 O 3: 0~12%, MgO: 0~8%, CaO: 0~14.5%, SrO: 0~ 24%, BaO: 0~13.5%, MgO + CaO + SrO + BaO: 9~29.5%, ZrO 2: 0~5%.
As a glass suitable for the thin glass G, an alkali-free glass having the following composition in the oxide-based mass percentage display can be used.
_{SiO 2: 58~66%, Al 2} O 3: 15~22%, B 2 O 3: 5~12%, MgO: 0~8%, CaO: 0~9%, SrO: 3~12.5% BaO: 0-2%, MgO + CaO + SrO + BaO: 9-18%.

The shock absorbing sheet as a shock absorbing material wound around the core 2 together with the thin glass G is wound around the core 2 so as to overlap with the thin glass G in order to prevent the thin glass G from being damaged. Between the thin glass plates G facing each other.
Specifically, the buffer sheet is disposed so as to cover the entire front and back surfaces of the thin glass G, and protects the entire front and back surfaces of the thin glass G. Therefore, it is possible to reliably prevent a situation in which the thin glass G of each glass layer, which is formed by winding the thin glass G around the winding core 2, is in direct contact with each other and is damaged. Further, even if any one of the thin glass sheets G of the respective glass layers on the outer periphery of the winding core 2 is damaged, the thin glass sheet G is sandwiched between the buffer sheets and exists between the flanges 3 and 3. The ratio of the glass powder generated due to breakage can be reduced.

  As the buffer sheet, in addition to interleaving paper and non-woven fabric, for example, ionomer film, polyethylene film, polypropylene film, polyvinyl chloride film, polyvinylidene chloride film, polyvinyl alcohol film, polypropylene film, polyester film, polycarbonate film, polystyrene film, It is possible to use resin sheets such as polyacrylonitrile film, ethylene vinyl acetate copolymer film, ethylene-vinyl alcohol copolymer film, ethylene-methacrylic acid copolymer film, nylon film (polyamide film), polyimide film, cellophane, etc. it can. In addition, it is preferable to use foamed resin sheets, such as a sheet | seat made from a polyethylene foamed resin, as a buffer sheet from a viewpoint of ensuring buffer performance and intensity | strength simultaneously. In addition, silica or the like may be dispersed in these resin sheets to improve the sliding property with the thin glass G. In this case, the slip generated between the thin glass G and the buffer sheet is absorbed by the sliding property. Can do.

  The buffer sheet can be provided with conductivity. If the conductivity is imparted, when the thin glass G is taken out from the core 2, it is difficult for the thin glass G and the buffer sheet to adhere to each other due to static electricity, so that the thin glass G and the buffer sheet can be easily separated. There is a characteristic. As a method for imparting conductivity to the buffer sheet, for example, when the buffer sheet is made of resin, a component that imparts conductivity, such as polyethylene glycol, may be added to the buffer sheet. Moreover, when a buffer sheet | seat is a slip sheet, making a conductive fiber into a slip sheet is mentioned.

Since the winding device 1 having the structure shown in FIG. 1 holds the end face of the roll body 4 between the flanges 3 and 3 without a gap, the thin glass G constituting the roll body 4 is interposed between the flanges 3 and 3. It does n’t move. For this reason, even if an impact or vibration is applied to the winding device 2 while the winding device 1 is being conveyed, the end surfaces of the thin glass G do not collide with the flange 3, and the end surfaces of the thin glass G collide with each other. Therefore, there is a feature that it is possible to provide the winding device 1 that can transport the thin glass sheet G without any wrinkles.
Further, since the flanges 3 and 3 cover the entire end surface of the roll body 4 of the thin glass G, it is possible to prevent an external impact from being applied to the end surface of the thin glass G during transportation and to protect the end portion of the thin glass G. .

In order to stably support the winding core 2 having the configuration shown in FIG. 1 by winding the strip-shaped thin glass G onto the winding region 2a of the winding core 2, after manufacturing the strip-shaped thin glass G by a glass manufacturing method such as a float method. The sheet glass G is wound to the required length together with the buffer sheet, and the roll body 4 is formed on the outer periphery of the winding core 2.
When the roll glass 4 is formed by winding the thin glass G around the winding core 2, the plurality of locking bolts 5 provided on the winding core 2 are loosened, the locking of the flanges 3 and 3 is released, and the flange 2 starts from the winding area 2a. The sheet glass G can be wound around the winding core 2 with the flange 3 and 3 being retracted or separated from the winding core 2. By these operations, when the thin glass G is wound around the core 2, the thin glass G can be safely wound while avoiding interference with the flange 3.
After the winding of the thin glass G, the flanges 3 and 3 are moved in the length direction along the winding core 2 to press the flanges 3 and 3 against the end face of the roll body 4, and as shown by an arrow P in FIG. With the both ends of the roll body 4 sandwiched by pressure, the locking bolts 5 are tightened to fix the locking ring 7 to the outer periphery of the winding core 2, and the flanges 3 and 3 are pressed so that both end surfaces of the roll body 4 are flanged 3. 3 can be held. The force for pressing the flanges 3 and 3 against the end face of the roll body 4 is preferably applied with a uniform pressure using a pressing device such as a cylinder device (not shown).
When the flanges 3 and 3 are pressed against the end face of the roll body 4, the end face position of the thin glass G and the end face position of the buffer sheet are made substantially the same position, so that both end portions of the roll body 4 are uniformly suppressed by the flanges 3 and 3. However, the positional relationship in the case where the end surface position of the buffer sheet and the end surface position of the thin glass sheet G are deviated will be described later.

As an example, the winding device 1 having the structure shown in FIG. 1 can be stably supported by a gantry 12 including a base 10 and stands 11 and 11 having a structure shown in FIG. The stand 11 is erected on the base 10 so as to be separated from the left and right, and a winding device in which both ends of the winding core 2 are placed on a concave bearing portion 11 a formed at the upper end of each stand 11. 1 can be supported horizontally.
If the winding device 1 is supported by the gantry 12 shown in FIG. 2, the winding device 1 can be stably supported on the gantry 12, so that the roll body 4 of the thin glass G is prevented from rolling and stable. Transport can be realized.
Further, since the winding device 1 is rotatably held in a state where it is supported by the gantry 12, the sheet glass G is fed out by a necessary length by removing the restraining plate 9 from the flanges 3 and 3 and rotating the winding core 2. be able to.
When the base glass side of the thin glass G is cut after the required length of the thin glass G is drawn out, the thin glass G having the required length can be obtained. Using this thin glass G, a display circuit can be obtained as a glass for a display device. It can be used for forming applications.

  By the way, in this embodiment, although the suppression plate 9 was provided in order to hold | suppress the thin glass G on the outermost periphery side, the fitting hole 3b which supports the suppression plate 9 is not only in the outer peripheral part of the flange 3, but in multiple inner peripheral parts. You may comprise so that the suppression board 9 can be replaced | exchanged according to the outermost periphery position of the thin glass G which was formed and took out predetermined length and remained on the core 2 side. By adopting this configuration, the thin glass G remaining on the winding core 2 side after the required length of the thin glass G is taken out is held by the restraining plate 9, and the thin glass G is stored and reused until it is next taken out. Can do.

“Second Embodiment”
3 and 4 show a cross-sectional structure of the winding device according to the second embodiment of the present invention. The winding device 20 according to this embodiment includes a metal cylindrical winding core 22 and the winding core. The metal donut disk-shaped flanges 21 and 23 attached at right angles to both ends in the length direction 22 are mainly configured. A thin glass sheet G is wound around the outer periphery of the winding core 22 together with a buffer sheet (not shown) to form a roll body 24, and left and right flanges 21 and 23 are pressed against both ends of the roll body 24 in the length direction.
The winding core 22 of the second embodiment is formed to have a length equal to or slightly shorter than the width of the thin glass G. A flange 21 is integrally fixed to one end portion (the left end portion in FIG. 3) of the winding core 22, and the entire outer periphery of the winding core 22 is a winding region 22 a of the thin glass G. A flange 23 separate from the winding core 22 is pressed against the open end of the winding core 22 by a chord material 25 at the side end (right end in FIG. 3).

The winding core 22 and the flange 21 are made of the same material as the winding core 2 and the flange 3 of the first embodiment. In this embodiment, the winding core 22 and the flange 21 are integrated by fixing means such as welding or adhesion. That is, a donut plate-like flange 21 is fixed at right angles to one end face of the cylindrical winding core 22, and a center hole 21 a of the flange 21 is communicated with a hollow portion 22 c inside the winding core 22.
The flange 23 on the other side of the winding core 22 has the same shape as the flange 21, but is different in that it is detachable from the winding core 22. In addition, a positioning ring member 26 is fixed around the center hole 23 a on the inner surface side of the flange 23, and the flange 23 is inserted into the other end of the winding core 22 by inserting the ring member 26 into the winding core 22. 22 is positioned with respect to the other end portion.

One end side of a plurality of string members 25 is attached to the inner peripheral portion of the flange 23 around the circumference, and the other end side of these string members 25 is moored to a plurality of support members 27 fixed to the inner side of the winding core 22. Has been. Each of the plurality of string members 25 has one end 25a fixed to the inner peripheral portion of the flange 23, and the other end 25b is engaged with the support 27, and the tension is applied to the flange 23 as shown in FIG. When viewed from the side, it is stretched so that it is in a state of hanging. In FIG. 3, only two chord members 25 are drawn, but the number of chord members 25 can be provided according to the pressing force necessary to press the end face of the roll body 24 by the flange 23. .
Therefore, as long as there are a plurality of strings 25, the number of strings 25 may be two or more as shown in FIG. Further, the direction in which the chord material 25 is stretched is not limited to the state shown in FIG. 3, and may be disposed along the inner surface of the core 22 along the length direction of the core 22. It is.
The string member 25 is formed of a rope body such as an elastic string, and is formed of a member that can be stretched between two points in a state where tension is applied, such as a lashing belt or a rope member. The flanges 21 and 23 are attached to both sides of the winding core 22 with their respective central axes aligned with the central axis of the winding core 22.

Although omitted in FIG. 3, one end 25 a of each string member 25 is locked to a locking portion such as a locking pin or a locking projection formed on the inner peripheral portion of the flange 23. One end 25 a is attached to the flange 23.
In the structure of the second embodiment shown in FIG. 3, the chord member 25 stretched on the inner side of the winding core 22 constitutes the means for pressing the flange 21 and the flange 23 against the end face of the roll body 24.

Since the length of the winding core 22 and the width of the thin glass sheet G are formed substantially equal to each other, a tensile force is applied to the end portion of the winding core 22 by the chord material 25 so that the flange 23 is attached to the end portion of the winding core 22. In the pressed state, the flange 23 is also pressed against the end face of the roll body 24 of the thin glass G. Therefore, the flanges 21 and 23 can be pressed against the end face of the thin glass G, and the roll body 24 can be stably held.
In the structure shown in FIG. 3, since the center holes 21 a and 23 a of the flanges 21 and 23 communicate with the hollow portion 22 c of the winding core 22, an operator connects the string member 25 to the flange 23 and the support 27. Work can be done easily.
The winding device 20 of this embodiment inserts a support rod so as to pass through the center hole 21a of the flange 21 and the center hole 23a of the flange 23, and this support rod is supported by the stand 11 of the gantry 12 shown in FIG. Thus, the winding device 20 can be rotatably supported.
In addition, the detailed positional relationship when the end surface positions of the flanges 21 and 23 and the thin glass G and the end surface positions of the buffer sheets inserted therebetween are not aligned will be described later.

“Third Embodiment”
5 and 6 show the cross-sectional structure of the winding device of the third embodiment according to the present invention. In the structure of the third embodiment, the same reference numerals are given to the structures equivalent to those of the second embodiment. To simplify their explanation.

“Fourth Embodiment”
FIG. 7 shows a cross-sectional structure of the winding device of the fourth embodiment according to the present invention. In the structure of the fourth embodiment, the same reference numerals are given to the structures equivalent to the structures of the second and third embodiments. To simplify their explanation.
The winding device 40 of this embodiment includes a metal cylindrical winding core 42 and metal donut disk-shaped flanges 41 and 43 attached at right angles to both ends in the length direction of the winding core 42. It is configured as a subject. In addition, a roll body 44 is formed by winding a thin sheet glass G together with a buffer sheet (not shown) around the outer periphery of the winding core 42, and the left and right flanges 41 and 43 are pressed against both ends in the length direction of the roll body 44. ing.

The winding core 42 of the fourth embodiment is formed slightly longer than the width of the thin glass G. A flange 41 is integrally fixed to one end portion (left end portion in FIG. 7) of the winding core 42, and the outer peripheral surface of the winding core 42 is a winding region 42 a of the thin glass G, and the other side of the winding core 42. A flange 43 that is separate from the winding core 42 is provided at the end (the right end in FIG. 7).
In the winding core 42 of the present embodiment, a screw portion 42b is formed on the outer periphery of the other side end portion, and a substantially entire area of the outer peripheral portion excluding the screw portion 42b in the winding core 42 is a winding region 42a of the thin glass G.
The flange 43 is formed in a donut plate shape, and a screw portion 43a is formed on the inner periphery of the center hole thereof. The flange 43 is screwed into the screw portion 42b of the winding core 42 by screwing the screw portion 43a. The other end of 42 is detachably attached. A ring-shaped spacer 46 is provided on the inner surface side of the flange 43. The roll body 44 is formed by screwing the flange 43 into the other end of the winding core 42 and pressing the spacer 46 against the end surface of the roll body 44 of the thin glass G. The roll body 44 is held on the outer periphery of the winding core 42 by sandwiching both end sides thereof by the flange 41 and the spacer 46. 7 shows a state in which the flange 43 is separated from the threaded portion 42b of the winding core 42 for convenience, but when the end surface of the roll body 44 is pressed by the flanges 41 and 43, the flange 43 is not attached to the winding core 42. Screwed into the screw portion 42b.

In the structure of the fourth embodiment shown in FIG. 7, means for pressing the flange 41 and the spacer 46 against the end face of the roll body 44 is constituted by the screw portion 42 b of the winding core 42 and the screw portion 43 a of the flange 43.
By fitting the screw portion 43a of the flange 43 to the screw portion 42b of the winding core 42 and sandwiching the roll body 44 of the thin glass G together with the flange 41 by the spacer 46, the roll body 44 can be stably held. In the present embodiment, the spacer 46 may be omitted, and the end surface of the roll body 44 may be pressed directly by using the inner surface of the flange 43 instead of the spacer 46.

Next, the position of the end surface of the buffer sheet that is wound around the winding core together with the thin glass sheet G in each of the embodiments described above will be described.
The thin glass G and the buffer sheet that are wound around the winding core to form the roll body can have the same width as an example. In this case, since both ends of the roll body are pressed and supported by the left and right flanges, the thin glass sheet G sandwiched between the left and right flanges is protected in a state of being sandwiched by the left and right flanges during transportation or transportation. At the same time, since it is sandwiched between the left and right flanges and hardly moves in the width direction, the end surface of the thin glass G does not collide with the flange during transportation, and therefore there is no possibility that the thin glass is damaged during transportation.
However, if the sheet glass G and the buffer sheet are large and have a width of several meters and are long, the widths of the sheet glass G and the buffer sheet can be made completely the same over their entire length. Not a translation. In this case, if the end surface of the thin glass G cannot be covered with the buffer sheet, the end surface of the thin glass G may be wrinkled. Therefore, the width of the buffer sheet is made slightly larger than the width of the thin glass G. It is preferable to protect the end face of the glass G.

When the width of the buffer sheet is slightly larger than the width of the thin glass G, the flange cannot be completely adhered to the thin glass G on both end faces of the roll body formed by winding around the winding core. It is preferable to employ the structure shown in FIGS.
8 and 9 show a case in which the roll sheet 51 is configured by co-winding the buffer sheet 50 and the thin glass G with respect to the core 2 shown in the first embodiment, and the buffer sheet 50 is slightly smaller than the thin glass G. A wide form is shown.

As shown in FIG. 9, the buffer sheet 50 in this form has a plurality of slits 50a intermittently formed in the lengthwise direction of the buffer sheet 50 at both ends in the width direction, and a protruding piece 50b is formed between the adjacent slits 50a and 50a. It is preferable to have a structured. Case where the roll 51 is wound co the winding core 2 thin glass plate G and the buffer sheet 50 to the length of the projecting pieces 50b, the length of the length projecting from the end face G ₁ of the thin plate glass G projecting piece 50b Is almost equal to Alternatively, the projecting piece 50b is slightly longer than the length protruding from the end face G ₁ of the thin plate glass G.

Thus pressed against the end face of the roll body 51 a flange 3 while being projected projecting piece 50b of the buffer sheet 50 from the end face G ₁ of the thin plate glass G in the roll body 51 by a predetermined pressing force, shown in FIG. 8 since it presses the flange 3 to the roll body 51 in a state of bending the protruding pieces 50b to the end surface G ₁ of the thin glass G protected with the projecting piece 50b of the buffer sheet 50, the end face of the thin plate glass G by a flange 3 G ₁ can be protected. FIG. 8 shows an example of a state in which the protruding piece 50b is slightly aligned on the upper side and the flange 3 is pressed. However, when the pressing force of the flange 3 is further increased, the flange 3 is further on the end face of the thin glass G than in the state shown in FIG. The flange 3 presses the roll body 51 while approaching and bending each protruding piece 50b upward.
In the state shown in FIG. 8, the flange 3 grips and holds the roll body 51 from both sides, but outside the end face G ₁ of the thin glass G, the protruding pieces 50 b partition the thin glass G for each thin glass G layer. since the separation, the end face G ₁ of the thin glass plate G projecting piece 50b of the buffer sheet 50 is protected.

Without providing the projecting piece 50b at the end portion of the buffer sheet 50, when the end of the buffer sheet 50 and structure in which protruded from the end face G ₁ of the thin glass G, when pressing the flange 3 to the roll body 51, the buffer sheet since protrusion portion 50 is deformed amorphous state, there is a risk that can not protect the end face G ₁ of the thin plate glass G.
Further, considering that the sheet glass G is fed out from the winding core 2 with the protruding portion of the buffer sheet 50 deformed in this irregular shape, the flange 3 is pressed when the sheet glass G is fed out from the winding core 2. There is a possibility that the protruding portion of the buffer sheet 50 deformed into an irregular shape is caught and the thin glass G is damaged. In this respect, if a plurality of slits 50a are provided to form the protruding piece 50b, when the thin glass G is fed out from the core 2, the protruding piece 50b is less likely to be caught by the flange 3, and the thin glass G can be drawn out smoothly. Therefore, it is possible to eliminate the possibility of damaging the thin glass sheet G during feeding.

FIG. 10 shows a case where the roll sheet 53 is formed by co-winding the buffer sheet 52 and the thin glass G with respect to the core 2 shown in the first embodiment, and the buffer sheet 52 is slightly wider than the thin glass G. Shows the form. In this example the length of the projecting portion 52a of the buffer sheet 52 protruding from the end face G ₁ of the thin plate glass G to the length L of the projection lengths in the roll body 53.
In this embodiment, the length L of the allowance can be set to about 0.5 mm to 10 mm. The reason is that if the length L of the protrusion is shorter than 0.5 mm, the end face of the thin glass G cannot be sufficiently protected, and if it is 10 mm or more, the buffer sheet 52 enters between the thin glasses G, and the glass breaks. It may be a cause.
