Description

Winding device and receiving device of thin glass {WINDING DEVICE AND STORING DEVICE FOR SHEET GLASS}

This invention relates to the winding-up apparatus which winds thin plate glass in roll shape, and hold | maintains, and the accommodation apparatus which accommodates the said winding-up apparatus, and uses for conveyance.

At present, when manufacturing the liquid crystal panel used as a display apparatus in mobile terminals, such as a small information terminal apparatus and a mobile telephone, after forming a circuit for display in a glass substrate of thickness 0.7mm, and constructing it as a liquid crystal panel, a glass substrate The back side of the substrate is shaved by wet etching to reduce the thickness, and the thickness is reduced to about 0.3 mm.

However, in the future, it is expected that this kind of liquid crystal panel for display devices will be manufactured using thin glass having a thickness of about 0.1 mm. When this thin glass about 0.1 mm in thickness is used for a display apparatus, it can be estimated that the manufacturing process of a display panel is renewed.

For example, since the thin glass of the thickness mentioned above can be wound in a roll shape to a winding core, when conveying a glass substrate from the factory which manufactures glass to the factory which manufactures a display panel, it becomes the mainstream in the present situation. Instead of the sheet-shaped conveyance, it can convey in roll state as rolled glass. Therefore, in the manufacturing plant of a display panel, the thin glass which was carried in the manufacturing line in the state of roll-shaped glass is cut out to a desired size, and put into the manufacturing process of a display panel.

The above-mentioned roll-shaped glass has a structure in which a strip-shaped thin glass is wound around the outer circumferential surface of the winding core, but in particular, the thin glass has a weak end surface strength, and a slight impact causes traces of shell-shaped cuts and cracks. In order to protect the end surface of thin glass, it is necessary to provide a flange to a winding core, and protect the edge of thin glass.

As a technique of winding this kind of thin glass on a winding core in a roll shape, it is conventionally a glass roll wound around a winding core in a state of overlapping with a buffer sheet so as to be spaced apart from the glass film on both sides in the width direction of the wound glass film. The structure which provided the flange and arrange | positioned the buffer means between the said flange and the width direction edge part of a glass film is known. (Refer patent document 1)

Japanese Patent Publication No. 2010-132348

In the technique described in Patent Document 1 described above, the buffer sheet is pushed out 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 glass film and the pushed out portion of the buffer sheet as the buffer means.

≪ First Embodiment >

EMBODIMENT OF THE INVENTION Hereinafter, although 1st Embodiment of the winding apparatus which concerns on this invention is described with reference to an accompanying drawing, this invention is not limited to embodiment described below.

FIG. 1: shows the cross-sectional structure of the winding apparatus of 1st Embodiment which concerns on this invention, The winding apparatus 1 of this embodiment is the metal cylindrical core 2 and the said winding core 2. It is composed mainly of the metal donut disc-shaped flanges 3 and 3 which are externally inserted and attached to both ends in the longitudinal direction of the slit. Moreover, the thin glass G is wound together with the buffer sheet (buffer material) which illustration is abbreviate | omitted in the longitudinal center part of the winding core 2, and the roll body 4 is formed, and the longitudinal direction both ends of this roll body 4 are flanges of right and left sides. It is sandwiched between (3, 3).

The constituent materials of the winding core 2 and the flange 3 are not particularly limited, but include high strength metal materials such as stainless steel, manganese steel, carbon steel, or aluminum alloy.

Since the winding core 2 winds and holds the strip | belt-shaped thin glass G of the predetermined | prescribed width, the strength which is not deformed by the pressure which winds up thin glass G is needed, The outer peripheral surface is thin glass G by contact with thin glass G It is preferable that the film is smoothed so as not to scratch. As an example, when the thin glass G wound around the winding core 2 has a thickness of about 100 μm (0.1 mm), a width of 1000 mm, and a length of 400 m, the weight is about 100 kg, so that the roll body 4 having such a weight can be held. Strength that is present is required for the winding core 2.

The flange 3 is movably mounted in the longitudinal direction of the winding core 2 by inserting the winding core 2 into the center hole 3a thereof.

In the longitudinal center portion of the winding core 2, a winding region 2a having a width capable of winding a strip-shaped thin glass G having a predetermined width is defined, and the thin glass G is wound in multiple layers on the winding region 2a. The flange 3 is arrange | positioned at the width direction both ends of this winding area | region 2a. In addition, a plurality of slit-shaped insertion holes 2b are formed at predetermined intervals in the circumferential direction of the take-up core 2, including the position where the flange 3 is disposed and extend so as to extend slightly outside the position. .

Locking bolts (locking zones) 5 are provided in the winding cores 2 so as to penetrate the peripheral wall 2A of the winding cores 2 in the thickness direction at the portions where the insertion through holes 2b are formed. The head part 5a of the locking bolt 5 protrudes outward of the winding core 2, and the nut 6 is screwed into the tip 5b of the locking bolt 5 protruding inward of the winding core 2. Are combined.

Moreover, the engagement ring 7 is externally inserted in the outer periphery of the part which formed the insertion through-hole 2b in the winding core 2, and passes through the perforation part 7a which penetrates in the radial direction of the engagement ring 7; The locking bolt 5 described above is penetrated so as to penetrate. That is, the locking bolt 5 is provided so as to penetrate the through hole 7a of the locking ring 7 in the example of FIG. 1 and to penetrate the insertion through hole 2b of the winding core 2, thereby winding the core. It penetrates through the circumferential wall 2A of (2). 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 to position the flange 3, and the flange 3 ) Presses the end face of the roll body 4, the locking bolt 5 and the locking ring 7 constitute the pressing unit and the locking unit of the flange 3.

The strip-shaped thin plate glass G wound by the winding core 2 is wound by the required number of layers, and the outermost peripheral part is locked by the suppression plate 9 attached to the flange 3. This restraining plate 9 becomes a curved board of the shape (tile shape) which matches the curved surface which the outermost peripheral end part of thin glass G draws, and is installed in the flanges 3 and 3 on either side. Specifically, a plurality of fitting holes 3b through which the suppressor plate 9 can be inserted are formed intermittently in the circumferential direction of the flange 3 at portions near the outer periphery of the inner surfaces of the flanges 3 and 3, The suppression plate 9 is arranged so as to penetrate both ends into the fitting holes 3b and 3b facing each other of the flanges 3 and 3 on the left and right sides, and the suppression plate 9 is an end of the outermost thin glass G. Press and hold.

Although the thin glass G has flexibility, in the state of being wound on the winding core 2, the thin glass G springs up with its own elastic force, so that the outer peripheral surface of the winding core 2 is pressed by pressing the outer peripheral surface of the thin glass G with the suppressor plate 9. The roll body 4 can be held stably.

It is preferable to attach the cushion layer which consists of a soft material to the back surface side of the restraining plate 9 so that the thin glass G may not be damaged. In addition, you may arrange | position a plurality of suppression plates 9 along the outer peripheral parts of the flanges 3 and 3, and press the outer peripheral surface of the roll body 4 in multiple places.

The left and right flanges 3 and 3 inserted into the winding core 2 are pressed from the left and right to sandwich the roll body 4 including the thin glass G therebetween. That is, the flange 3 on the left side of the winding core 2 is pressed to the left end surface of the roll body 4 at a predetermined pressure, and the flange 3 on the right side of the winding core 2 is the right side of the roll body 4. The end face is pressed by a predetermined pressure. Therefore, the roll body 4 is locked by the suppression plate 9 in the state sandwiched between the flanges 3 and 3 at predetermined pressure on both sides thereof. Moreover, each flange 3 is being fixed by the locking ring 7 which the locking bolt 5 fixed to the outer periphery of the winding core 2 in the state which the movement along the longitudinal direction of the winding core 2 was inhibited.

Since thin glass G is 1 micrometer-300 micrometers (preferably 10 micrometers-300 micrometers), and it has flexibility, when the outer diameter of the winding core 2 is a magnitude | size of 10 cm or more, it loads to thin glass G. Cold can be done without hanging. As an example, when applying 0.1 mm thin glass G, the outer diameter of the winding core 2 can be about 800 mm. Moreover, when thin glass G is thickness less than 1 micrometer, intensity | strength will become insufficient and handling will become difficult, and when the thickness of thin glass G exceeds 300 micrometers (0.3 mm), flexibility will become inadequate and the outer diameter of the winding core 2 will be It must be made larger than the size which can be conveyed.

The glass composition of the thin glass G is not particularly limited. Therefore, any of alkali-free glass, soda lime glass, mixed alkali-base glass or borosilicate glass or other glass may be used. In addition, the use of the thin glass G applied is not limited to a building, a vehicle, or these uses other than a flat panel display, and other various uses are mentioned.

Moreover, as glass suitable for thin glass G, the alkali free glass which has the following compositions can be used in the mass percentage display on the basis of an oxide.

SiO ₂ : 50 to 66%, Al ₂ O ₃ : 10.5 to 24%, B ₂ O ₃ : 0 to 12%, MgO: 0 to 8%, CaO: 0 to 14.5%, SrO: 0 to 24%, BaO : from 0 to 13.5%, MgO + CaO + SrO + BaO: 9 to 29.5%, ZrO _2: 0 to 5%.

As a glass suitable for the said thin glass G, the alkali free glass which has the following compositions can be used in the mass percentage display on the basis of an oxide.

SiO ₂ : 58 to 66%, Al ₂ O ₃ : 15 to 22%, B ₂ O ₃ : 5 to 12%, MgO: 0 to 8%, CaO: 0 to 9%, SrO: 3 to 12.5%, BaO : 0-2%, MgO + CaO + SrO + BaO: 9-18%.

The buffer sheet as a cushioning material wound around the winding core 2 together with the thin glass G is wound on the winding core 2 overlapped with the thin glass G in order to prevent scratching on the thin glass G, and the radius of the winding core 2 It interposes between thin glass G which opposes a direction.

In detail, the buffer sheet is arrange | positioned so that the whole surface of the front and back of thin glass G may be covered, and the whole front and back of the thin glass G is protected. Therefore, it is possible to reliably prevent the situation where the thin glass G of each glass layer which is formed by winding the thin glass G on the winding core 2 directly contacts and scratches. In addition, even if breakage generate | occur | produces in any one of the thin glass G of each glass layer of the outer periphery of the winding core 2, since the thin glass G is sandwiched between the buffer sheets, and exists between the flanges 3 and 3, The rate at which glass powder generated by breakage is scattered to the outside can be reduced.

As the buffer sheet, in addition to paper and nonwoven fabrics, for example, ionomer film, polyethylene film, polypropylene film, polyvinyl chloride film, polyvinylidene chloride film, polyvinyl alcohol film, polypropylene film, polyester film, polycarbo Nate film, polystyrene film, 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. Resin sheet of can be used. Moreover, it is preferable to use foam resin sheets, such as a polyethylene foam resin sheet, as a buffer sheet from a viewpoint of ensuring buffer performance and strength simultaneously. In addition, the slipperiness | lubricacy with thin glass G may be improved by disperse | distributing a silica etc. in these resin sheets, and in this case, the shift | offset | difference which arises between thin glass G and a buffer sheet can be absorbed by the slipperiness | lubricacy.

Electrical conductivity can be provided to a buffer sheet. When electroconductivity is provided, when taking out thin glass G from the winding core 2, since the adhesion by static electricity hardly arises between the thin glass G and the buffer sheet, peeling of the thin glass G and the buffer sheet becomes easy. There is this. As a method of providing electroconductivity to a buffer sheet, when a buffer sheet is resin, for example, adding the component which gives electroconductivity, such as polyethyleneglycol, to a buffer sheet is mentioned. Moreover, when a buffer sheet is a paper, what contains a conductive fiber in a paper is mentioned.

In the winding apparatus 1 of the structure shown in FIG. 1, since the end surface of the roll body 4 is sandwiched between the flanges 3 and 3, and is hold | maintained without gap, the thin glass G which comprises the roll body 4 is a flange ( It does not move between 3 and 3. For this reason, there is no possibility that the end surface of the thin glass G may collide with the flange 3, even if an impact or a vibration acts on the winding apparatus 2 while conveying the winding apparatus 1, and the end surfaces of the thin glass G are mutually Since it does not collide, there exists a characteristic which can provide the winding-up apparatus 1 which can be conveyed, without leaving a scratch on thin glass G.

Moreover, since the flanges 3 and 3 cover all the end surfaces of the roll body 4 of the thin glass G, the impact is prevented from being applied to the end surface of the thin glass G from the outside during the conveyance, thereby protecting the end of the thin glass G. do.

In order to wind and stably support strip-shaped thin glass G on the winding core 2 of the structure shown in FIG. 1, after manufacturing strip-shaped thin glass G by glass manufacturing methods, such as a float method, a winding core The thin glass G is wound around the winding area 2a together with the buffer sheet by the required length, and the roll body 4 is formed on the outer circumference of the winding core 2.

When the thin glass G is wound around the winding core 2 to form the roll body 4, the plurality of locking bolts 5 provided on the winding core 2 are loosened to lock the flanges 3 and 3. The glass 3 can be wound around the winding core 2 in a state where the flange 3 is evacuated and separated from the winding region 2a, or the flanges 3 and 3 are removed from the winding core 2. By these operations, when the thin glass G is wound around the winding 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 is finished, the flanges 3 and 3 are moved along the winding core 2 in the longitudinal direction thereof to press the flanges 3 and 3 to the end faces of the roll body 4, and FIG. 1 arrow P As shown in the figure, the locking bolts 5 are fastened to the outer circumference of the winding core 2 by fastening the locking bolts 5 with both ends of the roll body 4 at a constant pressure. By pressing, both end faces of the roll body 4 can be held by the flanges 3 and 3. It is preferable that the force which presses the flanges 3 and 3 to the end surface of the roll body 4 adds equal pressure using a pressurization apparatus, such as a cylinder apparatus which omit illustration.

When the flanges 3 and 3 are pressed against the end faces of the roll body 4, the end face positions of the thin glass G and the end face positions of the cushioning sheet are approximately the same positions, so that the rolls with the flanges 3 and 3 roll. Although both end parts of (4) can be suppressed uniformly, the positional relationship in the case where the end surface position of a buffer sheet and the end surface position of thin plate glass G shift | deviate is demonstrated later.

As an example, the winding apparatus 1 of the structure shown in FIG. 1 can be stably supported by the mount 12 which consists of the base 10 and the stands 11 and 11 of the structure shown in FIG. Stand 11 is installed on the base 10 spaced apart from side to side, and both ends of the take-up core 2 on the concave-shaped bearing portion (11a) formed on the upper end of each stand (11) The winding device 1 can be supported horizontally.

If it is the winding device 1 of the state supported by the mount 12 shown in FIG. 2, since the winding device 1 can be stably supported on the mount 12, the cloud of the roll body 4 of thin glass G is thin. Can be prevented and stable transportation can be realized.

Moreover, since the winding apparatus 1 is hold | maintained rotatably in the state supported by the mount 12, the thin plate glass G by removing the restraining plate 9 from the flanges 3 and 3 and rotating the winding core 2 Can be dispensed as needed.

After the thin glass G is fed out to the required length, and the base end side of the thin glass G is cut, the thin glass G of the required length can be obtained, and the thin glass G is used as a glass for a display device for use in display circuit formation and the like. Can be.

By the way, in this embodiment, although the restraining plate 9 was provided in order to press the thin-plate glass G of the outermost peripheral side, the fitting hole 3b which supports the restraining plate 9 is not only the outer peripheral part of the flange 3 but an inner peripheral part. It may also be configured so that the restraining plate 9 can be reattached to the outermost circumferential position of the thin glass G remaining on the winding core 2 side after being formed in plural and taken out by a predetermined length. By setting it as this structure, after taking out the required length thin glass G, the thin glass G which remained on the winding core 2 side is pressed by the suppression plate 9, the thin glass G can be stored and used again until the next time to take out. have.

Fig. 7 shows a cross-sectional structure of the winding apparatus of the fourth embodiment according to the present invention. In the structure of the fourth embodiment, the same reference numerals are given to structures equivalent to those of the second and third embodiments, and their descriptions are given. Simplify.

The winding device 40 of this embodiment is the metal cylindrical donut disk-shaped flange and the metal donut disk-shaped flanges 41 and 43 attached to the both sides of the longitudinal direction of the winding core 42 at right angles. Is mainly composed of). Moreover, the roll body 44 is formed by winding the thin glass G together with the buffer sheet which omits illustration in the outer periphery of the winding core 42, and the right and left flanges 41 and 43 are provided at the both ends of the roll body 44 in the longitudinal direction. Is configured to be pressed.

The winding core 42 of 4th Embodiment is formed slightly longer than the width | variety of thin glass G. As shown in FIG. The flange 41 is integrally fixed to one end (left end in FIG. 7) of the winding core 42, and the outer circumferential surface of the winding core 42 becomes the winding region 42a of the thin glass G, and the winding core ( At the other end (right end in FIG. 7) of 42, a flange 43 separate from the winding core 42 is provided.

In the winding core 42 of this embodiment, the thread part 42b is formed in the outer periphery of the other end part, and almost the whole area | region of the outer peripheral part except the screw part 42b in the winding core 42 is the winding area | region 42a of the thin glass G It is.

Although the said flange 43 is formed in the shape of the donut plate, the threaded part 43a is formed in the inner periphery of the center hole, and the flange 43 screwed the threaded part 43a to the threaded part 42b of the winding core 42. It is attached and detachably attached to the other end of the winding core 42. A ring-shaped spacer 46 is provided on the inner surface side of the flange 43, and the flange 43 is screwed to the other end of the winding core 42 to attach the spacer 46 to the end of the roll body 44 of thin glass G. Both ends of the roll body 44 are sandwiched between the flange 41 and the spacer 46 by being pressed against the lower surface, and the roll body 44 is held on the outer circumference of the winding core 42. In addition, although FIG. 7 shows the state which isolate | separated the flange 43 from the screw part 42b of the winding core 42 for convenience, when pressing the end surface of the roll body 44 with the flanges 41 and 43, The flange 43 is screwed to the threaded portion 42b of the winding core 42.

In addition, in this embodiment, the spacer 46 may be abbreviate | omitted and the end surface of the roll body 44 may be directly pressed instead of the spacer 46 by the inner surface of the flange 43.

Next, the buffer sheet end surface position wound around the winding core with thin glass G in each embodiment demonstrated above is demonstrated.

The thin glass G and the shock absorbing sheet which wind around a winding core and form a roll body can use the thing of the same width as an example. In this case, since both ends of the roll body are pressed and supported by the right and left flanges, the thin glass G held between the left and right flanges is protected while being held by the left and right flanges during conveyance or transport, and between the right and left flanges. Since the end face of thin glass G is not collided with a flange during conveyance because it is inserted in the width direction and cannot move substantially in the width direction, there is no possibility that a thin glass may be damaged during conveyance.

However, in the case where the width of the thin glass G and the buffer sheet is long as large as several meters, the widths of the thin glass G and the buffer sheet may not be aligned exactly the same over their entire length. In this case, when the end surface of the thin glass G cannot be covered with the buffer sheet, there is a possibility that the end surface of the thin glass G may be scratched. Therefore, the width of the buffer sheet is slightly larger than the width of the thin glass G, so that the thin glass G It is preferable to plan the end face of the.

In the case where the width of the buffer sheet is slightly larger than the width of the thin glass G, the flange may not be completely adhered to the thin glass G on both end faces of the roll body formed by winding the winding core. It is preferable to employ | adopt the structure shown in FIG.

8 and 9 show a case in which the buffer sheet 50 and the thin glass G are wound together to form the roll body 51 with respect to the winding core 2 shown in the first embodiment, and the buffer sheet 50 is the thin glass G. It is slightly wider.

In the buffer sheet 50 of this embodiment, as shown in FIG. 9, a plurality of slits 50a are formed intermittently in the longitudinal direction of the buffer sheet 50 at both ends in the width direction, and adjacent slits 50a and 50a are provided. It is preferable to set it as the structure in which the protrusion piece 50b was formed in the liver. The length of the protruding piece 50b is such that when the thin glass G and the buffer sheet 50 are wound together on the winding core 2 to form the roll body 51, the length protruding from the end face G ₁ of the thin glass G protrudes. It is almost equal to the length of the piece 50b. Alternatively, a length greater than the projection piece (50b) which projects from the end face of the thin plate glass G ₁ G is slightly longer.

So the rolche 51. Flange (3) a projecting segment (50b) of the cushioning sheet 50 from the end face G ₁ of the sheet glass G in which the protruding state in the end face side of rolche 51 at a predetermined pressing force When pressed, the projection piece (50b) a state so as to press the flange 3 to rolche 51, the thin plate glass G end face the G ₁ the buffer sheet 50 of the bending as shown in Fig. 8 protected by a projection piece (50b), and it is possible to protect the end face of the thin plate glass G ₁ G by the flange 3. FIG. 8 shows an example of a state in which the flange 3 is pressed by aligning the protruding piece 50b to the upper side somewhat. However, when the pressing force of the flange 3 is further increased, the flange 3 is more than the state shown in FIG. 8. The flange 3 presses the roll body 51 as it is close to the end face of the thin glass G, and the protruding pieces 50b are bent upward.

In the state shown in Fig flange 3 is rolche 51 for holding the grip from both sides, but, in the end faces outside of the G ₁ of the thin plate glass G projection pieces (50b) for each layer of each sheet glass G the thin plate glass G since the compartments separately, and protects the projecting piece (50b) of each sheet of glass G to the end face G ₁ cushioning sheet 50 of the.

Without providing the projection pieces (50b) at an end of the buffer sheet 50, when the configuration in which protrudes an end portion of the cushioning sheet 50 from the end face G ₁ of the thin plate glass G, rolche the flange (3) (51 ), The protruding portion of the buffer sheet 50 is deformed into an indefinite state, so that the end face G ₁ of the thin glass G may not be protected.

In addition, when taking out thin glass G from the winding core 2 in the state which has the extruded part of the buffer sheet 50 deformed in this amorphous state, when feeding thin glass G from the winding core 2, There is a possibility that the extruded portion of the shock-absorbing sheet 50 deformed into an irregular shape pressed against the flange 3 is caught and the thin glass G is damaged. In this case, when a plurality of slits 50a are provided to form the protruding pieces 50b, the protruding pieces 50b are less likely to be caught by the flange 3 when the thin glass G is fed from the winding core 2, Since the thin glass G can be fed smoothly, the possibility of damaging the thin glass G at the time of feeding can be eliminated.

FIG. 10: is the case where the buffer sheet 52 and the thin glass G are wound together and the roll body 53 is comprised about the winding core 2 shown in 1st Embodiment, and the buffer sheet 52 is slightly smaller than the thin glass G. FIG. It shows the form made wide. In this example, the length of the protruding portion 52a of the buffer sheet 52 pushed out from the end surface G ₁ of the thin glass G in the roll body 53 is referred to as the protruding clearance length L.

This protrusion clearance length L can be about 0.5 mm-about 10 mm in this embodiment. This reason is that when the projection clearance length L is shorter than 0.5 mm, the end face of the thin glass G cannot be sufficiently protected, and when it is 10 mm or more, the shock absorbing sheet 52 intervenes in the middle of the thin glass G, causing the glass to break. This is because it may be.
