Technical field
The present invention relates to a kind of mother metal that is constituted by sheet glass that makes and soften and the thin glass ribbon of this mother metal of shaping ejecting plate thickness rate, thus method and the device thereof of manufacturing glass-pane shaping product.
Background technology
In the past, it is good that the sheet glass of the substrate purposes of semiconductor element, display applications etc. required to make Flatness and the surfaceness on surface.Yet, when utilizing the float glass process extensively popularized as the manufacture method of current sheet glass etc. to make thin sheet glass, in order to form the sheet glass that is applicable to above-mentioned purposes, preferably the surface of the sheet glass after being shaped is ground and improve Flatness, the surfaceness on surface.For this reason, the technical scheme of the precision of various raising abrading glass plates occurred, but in order to improve grinding precision, needed cost unnecessary milling time and labour, therefore had problems sometimes aspect manufacturing cost, the cost of equipment.
Therefore, known a kind of the use by the thickness of slab with regulation and the surfaceness mother metal (hereinafter referred to as " sheet glass mother metal ") that constitutes of good sheet glass to a certain extent, make its thermoplastic, sheet glass to soft state stretches, and can produce the shape method that pulls into again (for example with reference to patent documentation 1,2) of the sheet glass of needed thickness of slab and sheets of glass in apparent good order and condition thus.
This pulls into the shape method again as the sheet glass mother metal (for example about thickness 5mm) of heavy wall is heated into more than the softening temperature, and it is stretched and makes the cross section known than the method that unfertile land forms (for example about thickness 0.1mm) again.
Fig. 5 represents a this conventional example that pulls into the shape device again.The shape device 100 that pulls into again shown in Figure 5 possesses: the sheet glass mother metal 101 of the rectangular shape of vertical ground suspention supporting lengthwise also is configured to move up and down freely mother metal feedway 102; The heating unit 103 and the annealing device 105 that below this mother metal feedway 102, arrange; And be used for the softening part of sheet glass mother metal 101 tractive and the tractive tube 106 that stretches downwards.

Summary of the invention
Pulling into again in the shape device 100 of existing structure shown in Figure 5, thereby under the state that utilizes pulling device 106 tractive sheet glass mother metals, this sheet glass mother metal heated and make it softening when pulling into shape glass ribbon 107 again, certainly exist the front of glass ribbon and the problem that rear end side is wasted.
For example, at first heat the part of softening by heating unit 103 begin till pull into shape in stable condition again from production during, existence can't be produced the problem of the glass-pane shaping product of good quality.This be because, shape and the temperature distribution instability of the glass ribbon in the heating unit.
After producing beginning, when through the specified time, supply with and the desirable thermal process of process to heating unit 103, carry out the needed shape that pulls into again, thereby obtain the glass-pane shaping product 109 as non-defective unit.
In addition, mother metal feedway 102 is controlled sheet glass mother metal 101 limits by the claw 102a limit that is formed on its underpart and is descended, and produces under near the state of heating unit 103 at claw 102a and finishes.Yet in this case, residual in the inside of heating unit 103 the sheet glass mother metal 101 by claw 102a supporting is arranged is the part from the claw to the shut-off device of glass ribbon, therefore exists the glass ribbon of this residual part also to become the problem of waste.Certainly, the length difference of the part of wasting according to the scale that pulls into the shape device again etc., but when using the sheet glass mother metal of total length 3m, form the waste about front 1m, about rear end side 1m sometimes.
That is, when using the pulling into shape device 100 again and come formed glass sheets molding 109 of existing structure shown in Figure 5, the waste of material will inevitably appear, therefore in order to boost productivity, and usually will be with the thickness of slab (t of sheet glass mother metal 101
0) with the ratio (t of the thickness of slab (t) of glass-pane shaping product 109
0/ t) extensibility of expression is carried out the production of glass-pane shaping product 109 than the highland setting as far as possible.

Described heating unit 6 is made of the well heater of the vertical stove core barrel 6A of cross section rectangular shape and not shown a plurality of resistance-types of arranging around it.This heating unit 6 makes the side's of stove core barrel 6A peristome make progress as inlet portion 6B, and makes the opposing party's peristome, generally perpendicularly be arranged on the below of mother metal feedway 5 downwards as the 6C of export department.Stove core barrel 6A forms the size that the sheet glass mother metal 1 that lays out from reel 3 can be inserted from inlet portion 6B to stove core barrel private side and discharge from the 6C of export department downwards.
Need to prove that at this, sheet glass mother metal 1 enters heating unit and softens, begin to be thinned to the sheet glass that finishes to be shaped and cut off as the band shape of glass-pane shaping product till before from thickness of slab and be called glass ribbon.And, at this, state after the glass-pane shaping product refer to after shaping glass ribbon cut off as intermediate or finish the sheet glass of product, the situation and the situation that is wound into the tubular sheet glass of tubular that comprise flat sheet glass, also can be can be under the form of subsequent processing or client's operation transportation, the sheet glass after glass pane surface is carried out coating or stackedization of pad pasting.But the calculating of extensibility is in this case only calculated according to the thickness of slab of the glass part of sheet glass.
When the sequence explanation pulls into the principle of shape again by the time, if effect has the sheet glass mother metal of tension force to be heated, softens, then thickness of slab attenuation gradually is in the process of cooling, the minimizing of thickness of slab stops and becoming constant thickness, by this constant thickness partly being cut off the glass-pane shaping product that form.In this case, because effect all the time has tension force on the sheet glass mother metal, therefore in softening moment, thickness of slab attenuation.In above-mentioned definition, the glass of this part becomes glass ribbon.Thus, make the sheet glass mother metal heat, soften and be shaped by the time sequence, but under the situation of the spatial apparatus structure in the explanation stable formation, in fact glass ribbon is heated.
In addition, also can be following structure: the internal feed to the stove core barrel purifies air, N
2Gas, Ar gas, He gas or their mixed gas are finished the stretching of glass ribbon the environment of not sneaking into impurity etc. from heating atmosphere.
For the mode that makes by heating unit 6 width and the thickness glass ribbon 2B after dwindling with residual strain or the fictive temperature of control glass and avoid breaking is reduced to temperature arbitrarily near normal temperature, and disposed annealing device 7.Need to prove that the annealing device 7 of present embodiment is with respect to heating unit 6 split settings, but preferably be difficult to separate and with heating unit 6 integrated structures.This is because heating region is difficult in fact separate with the slow cooling zone, both integrally formed glass temperature gradients.
Described pulling device 8 forms following structure: disposed adjacent has two by the tube 12 of bolster 11 horizontal supportings, to be clamped the glass ribbon 2 of deriving from the 7C of export department of annealing device 7 by tube 12,12 and modes of each 12 rotation are constituted.By described tube 12,12 clamping glass ribbons 2 and with suitable speed tractive glass ribbon 2, can pull out sheet glass mother metal 1 from described mother metal feedway 5 thus.Pulling device 8 both can be arranged in the heating unit 6 or in the annealing device 7, also can arrange a plurality of.And tube 12,12 both can contact with whole of the width of glass ribbon, also can only contact with the part of width.
Shut-off device 9 is built-in with the bending shut-off device that can with making shearing force along this line effect glass ribbon 2 be cut off along the cutting unit of its width formation line for by its inner glass ribbon 2B.Be built in the known glass severing device that the manufacturing line of cutting unit in this shut-off device 9 and bending shut-off device and general sheet glass possesses and be equal to, so detailed.Need to prove that shut-off device 9 is not limited to the unitized construction of cutting unit and bending shut-off device, also can be to have the chopping up apparatus of the mode of not cutting off on line ground by laser beam, or utilizes structure arbitrarily such as device that laser beam directly fuses.
Winch spool (wind2) the 10th can will pass through the reel device of necessary length of glass ribbon 2 behind pulling device 8 and the shut-off device 9.
Then, the manufacturing installation 20 of the glass-pane shaping product that use described structure is described, is made the method for glass-pane shaping product 15 by sheet glass mother metal 1 via glass ribbon 2.

Therefore, the prior art big extensibility α that tries one's best for the productivity β that improves material adopts is that target is developed.
On the other hand, in the present invention, be accompanied by the glass requirement of plate molding as thin as a wafer of wide cut, specially by extensibility α is provided little manufacture method, make high-quality wide cut glass as thin as a wafer the production of plate molding become possibility.
When the width of establishing desirable glass-pane shaping product is w, the width w of sheet glass mother metal 1
0Be expressed from the next.
w
0≒α×w…（12）
That is, the width of sheet glass mother metal 1 determines the size of the width of manufacturing installation, and therefore with respect to the width w of the glass-pane shaping product that require, extensibility means for a short time by the little manufacturing installation of width and can produce.Pulling in the shape, in order to obtain high-quality glass molded article, the control of the control of the temperature distribution of width or the movement of glass ribbon or traction force is most important again, the therefore situation that the width of device can the be not wide production that can bring high quality glass.And the manufacturing installation that width is little also can be realized cost degradation.
In other words, set extensibility α lessly mean that the productivity of material is little.In the present invention, in order to obtain the productivity of material to greatest extent, also provide the method that prolongs sheet glass mother metal length L.In the present invention, because extensibility α is little, therefore the glass below making thickness 0.1mm during plate, can be made as the thickness of sheet glass mother metal below the 0.3mm as thin as a wafer.0.3mm following sheet glass has flexible and is wound into tubular easily.That therefore, can implement can't to implement in the prior art draws moulding method again based on the sheet glass mother metal of tubular.And, compared with the past, can prolong sheet glass mother metal length L tremendously.
In addition, the viewpoint of productivity is not only the viewpoint of material.It also is a very big problem that time per unit can be produced the so temporal productivity of how many glass-pane shaping product (hereinafter referred to as " time productivity ").Pulling into again in the shape based on existing method, can't carry out the continuous supply of sheet glass mother metal in fact, therefore except the pure production time, also produce to change the sheet glass mother metal time, reach glass-pane shaping product and become the required time of stabilization before the stable molding condition of non-defective unit, time productivity reduction.In embodiment in the past shown in Figure 5, this replacing time and stabilizing take frequently produce, and are difficult to improve time productivity.
On the other hand, in the manufacture method of setting extensibility α, can use the sheet glass mother metal of tubular, so time productivity improves also tremendously as the present invention lessly.
At the use of the sheet glass mother metal of tubular, i.e. L
0Very large creating conditions down, preferred development shortened L as far as possible in the past
1The manufacturing installation of structure, with respect to this, by prolonging L a little
1, can not cause big influence to productivity, and can realize high-qualityization of glass molded article, for example can produce the little glass-pane shaping product of compressed value that reduce behind the fictive temperature.
From above background, when the manufacturing installation 20 of the glass-pane shaping product that use present embodiment forms, set for than forming in the past the little extensibility of setting in the shape device of extensibility that pulls into again.Particularly, as extensibility, be made as more than 1.5 and less than 10, preferably be made as more than 1.5 and below 7, more preferably be made as more than 1.5 and below 5, further preferably be made as more than 1.5 and 4 following extensibilitys form, need not increase more than necessary and can produce by device thus.
Need to prove, when extensibility less than 1.5 the time, the ratio of stretching is low excessively, and is nonsensical in the practicality.Need to prove, when extensibility surpasses 5, though obtain to produce the effect of the present invention of the wide glass-pane shaping product of the width of requirement, but be that situation below 5 is compared with extensibility, the width that has a sheet glass mother metal increases and situation and the producing apparatus of operability variation become big situation.Therefore, extensibility becomes preferred scope below 5.
Following table 1 expression extensibility α is 5 the thicknesss of slab (mm), the relation of width (m) of thickness of slab (mm), width (m) and glass-pane shaping product of sheet glass mother metal 1 when following.
[table 1]
As shown in table 1 like that if extensibility α is below 5, even then about the wide size that is lower than 2m that is set at of the plate of sheet glass mother metal 1, width that also can the glass-pane shaping product that increase obtains in the scope of 0.2～0.6m(200mm～600mm).And, by using the sheet glass mother metal 1 that is constituted by sheets of glass, can produce the glass-pane shaping product of thickness of slab 0.03mm～0.1mm.
In addition, if the glass-pane shaping product that obtain by manufacturing process of the present invention, then the effect that pulls into the glass ribbon that obtain excellent flatness of shape method shown in original again for what is called can directly be inherited, and therefore can access the high-quality glass-pane shaping product that width is wide and flatness is high.
