Sheet glass producing apparatus 12 shown in Figure 1 from upstream side downstream side dispose float bath 20, molten tin bath case (dross box) 22, leer 24 and line of cut processing unit (plant) 10 successively.
In float bath 20, come molding glass band 14 through dissolving glass to the bath face supply that dissolves tin 28 continuously.Hoisting type roller 30 through molten tin bath case 22 draws upper glass band 14 from dissolving tin 28.Then, glass ribbon 14 is carried in leer 24 through lehr rollers 26, thereby is cooled to room temperature gradually through in the molten tin bath case 22.
Through line of cut processing unit (plant) 10 and not shown breaker, on the width of glass ribbon 14, cut off glass ribbon 14 through leer 24.Breaker is that the line of cut on the surface of glass ribbon 14, processed applies bm and cuts off the known device of glass ribbon 14 along line of cut.
In addition; Before the line of cut on the width of processed glass band 14 on the surface of glass ribbon 14; Through not shown line of cut processing unit (plant), in advance at the line of cut of processing on the surface at the width two ends of glass ribbon 14 on the carrying direction of the carrying direction of glass ribbon 14.The parting tool preferred disposition of this line of cut processing unit (plant) is above the carrying roller.Of the back, after cutting off glass ribbon on the width,, cut off the two ends of glass ribbon along the line of cut of direct of travel through not shown breaker.From being that the angle of the line of cut on the direction of processing carrying stably on the glass ribbon 14 of 0.7mm is considered at thickness, preferably with this parting tool carrying roller in opposite directions also have with after the hardness that equates of the hardness of the supporting roll (bracing member) 48 stated.In addition, preferably this parting tool be applied to operating force on the glass ribbon 14 also be set at after the operating force of the parting tool 44 stated equate.
Like Fig. 2, shown in Figure 3, the line of cut processing unit (plant) 10 of the line of cut on the width of processed glass band 14 has a plurality of carrying roller 32,34,36,38,40,42, parting tool 44 and supporting roll 48.
The glass ribbon 14 that the carrying of carrying roller 32 ~ 42 is taken out of from leer 24 (with reference to Fig. 1), and be configured on the orthogonal direction of carrying direction with glass ribbon 14.In addition, the radical of carrying roller 32 ~ 42 is not limited to 6.
On the other hand, parting tool 44 is by the surface that is pressed in the glass ribbon 14 of carrying on the roller 32 ~ 42 carrying, and through after move with respect to the carrying direction of glass ribbon 14 is oblique on the glass ribbon 14 of unit in carrying of advancing stated.Thus, on the surface of glass ribbon 14, process the line of cut 46 of the carrying direction that is orthogonal to glass ribbon 14.In addition, use superhard alloy ratch, line break bar etc. as parting tool 44.In addition; The transporting velocity with glass ribbon 14 be made as v, with the gait of march of parting tool 44 be made as w, when parting tool 44 is made as θ with respect to the travel angle of the carrying direction of glass ribbon 14; This gait of march w is set at w=v/cos θ, thus with the orthogonal direction of carrying direction of glass ribbon 14 on processing line of cut 46.At this, the travel track of establishing parting tool 44 is A (with reference to Fig. 2, Fig. 3).
Be formed with at lower position and be used to make supporting roll 48 at the travel path C that on the travel track B of travel track A, advances along the travel track A of parting tool 44.And in order to form this travel path C, carrying roller 32 ~ 42 is divided into two portions in the axial direction.That is, carrying roller 32 is divided into carrying roller 32A, 32B, likewise; Carrying roller 34 is divided into carrying roller 34A, 34B; Carrying roller 36 is divided into carrying roller 36A, 36B, and carrying roller 38 is divided into carrying roller 38A, 38B, and carrying roller 40 is divided into carrying roller 40A, 40B; And carrying roller 42 is divided into carrying roller 42A, 42B.Thus, form the travel path C that supporting roll 48 passes through.In addition, carrying roller 32 ~ 42nd, the roller that in the oblique mobile scope of parting tool 44, disposes at least.
The back side butt of supporting roll 48 and glass ribbon 14 bears parting tool 44 via glass ribbon 14 and is applied to the operating force on the glass ribbon 14, and the elastomerics that is formed by soft elastic material constitutes.This supporting roll 48 is advanced with equidirectional and identical speed with parting tool 44 through the unit 50 of advancing shown in Figure 4 integratedly.
The unit 50 of advancing is feed screw devices, is made up of motor 52, the feed screw 54 and the nut 58 that are connected with the output shaft of this motor 52.Be equipped with the cylinder 60 that constitutes driving and reversing mechanism on the top of nut 58, be provided with support 66 on the top of the piston 62 of this cylinder 60, this support 66 rotates supported roller 48 freely through axle 64.In addition, motor 52 is controlled to the driving part of parting tool 44 synchronous by not shown control part.
Thereby according to the unit 50 of advancing of such formation, CD-ROM drive motor 52 moves nut 58, makes supporting roll 48 move to a position as stand-by station.In addition, this moment, parting tool 44 was in the standby of the top position of supporting roll 48.Then, when parting tool 44 descends when beginning to process line of cut towards glass ribbon 14, piston 62 and synchronously elongation of this action, supporting roll 48 moves to the b position.Thus, the back side butt of supporting roll 48 and glass ribbon 14 bears the pressing force with the parting tool 44 of the surperficial butt of glass ribbon 14.Then, through the feed motion of motor 52, the c position of supporting roll 48 to move to the processing terminal position with equidirectional and with identical speed with the state and the parting tool 44 of the back side butt of glass ribbon 14.
Thus, according to this line of cut processing unit (plant) 10, as Fig. 2, processing line of cut 46 on the surface of glass ribbon 14.In addition, because below parting tool 44, always there is rubber-like supporting roll 48, so can on the surface of the glass ribbon of carrying continuously through carrying roller 32 ~ 42 14, stably process line of cut 46.
If processed line of cut 46, then this back piston 62 carries out contractive action, and supporting roll 48 moves to the d position of keeping out of the way from glass ribbon 14.Then, through motor 52 supporting roll 48 is restored and move to original a position, carry out standby up to next time processing action.In addition, parting tool 44 too, if accomplished line of cut processing, the top of then keeping out of the way glass ribbon 14 turns back to the processing starting position.In addition, the unit 50 of advancing is not limited to the feed screw device, can be the feed mechanism that is made up of rack-and-pinion, also can be the feed mechanism that utilizes band to drive.And the diameter of carrying roller 32 ~ 42 is 50 ~ 300mm, preferred 150 ~ 250mm.
But as previously mentioned, the line of cut processing unit (plant) 10 of first embodiment is processed line of cut 46 on the surface of the glass ribbon below the thickness 0.7mm 14.
For processing line of cut 46 on the surface of such glass ribbon 14, this line of cut processing unit (plant) 10 is set to following mode.
That is, according to line of cut processing unit (plant) 10, supporting roll 48 is to be made up of the elastomerics that soft elastic material forms, and the operating force that parting tool 44 is applied on the glass ribbon 14 is set at 1.6 ~ 8.0N.
Not under the situation of metal system roller of the elastomerics that forms by soft elastic material but hard at supporting roll 48; Because the hardness of this roller is big; Parting tool 44 is beated on glass ribbon 14 when parting tool 44 is advanced, and is difficult to the surface working successive line of cut 46 at glass ribbon 14.In addition, the crack of line of cut is developed to more than the appropriate depth of sheet glass, and sheet glass is easy to fragmentation.
If parting tool 44 is applied to operating force on the glass ribbon 14 less than 1.6N, then line of cut 46 shoals with respect to the degree of depth of glass ribbon 14, in breaker, is difficult to the line of cut 46 of processing appropriate depth on the surface of glass ribbon 14.On the other hand, if operating force surpasses 8.0N, then, exist parting tool 44 can poke the problem of glass ribbon 14 because operating force is big.
Thereby when processing line of cut 46 on the surface of the glass ribbon 14 below thickness 0.7mm, preferred supporting roll 48 is elastomericss that soft elastic material forms, and the operating force that parting tool 44 is applied on the glass ribbon 14 is set at 1.6 ~ 8.0N.Thereby, according to the line of cut processing unit (plant) 10 of first embodiment that is set at this mode, can on the surface of the glass ribbon 14 below the thickness 0.7mm that carries continuously through carrying roller 32 ~ 42, process stable line of cut 46.

The hardness of preferred this supporting roll 48 is 50 ~ 90 ° (according to JIS K6301 spring loaded A shapes).
If the hardness of supporting roll 48 is less than 50 °; Then because of the soft line of cut processing parts that make 44 of parting tools push the glass ribbon 14 of butt of supporting roll 48 are absorbed in supporting roll 48, on said line of cut processing part, apply recoverable deformation the elastic restoring force of supporting roll 48.Therefore, because on the line of cut processing part, act on unnecessary power, so this line of cut processing part is easy to breakage.On the other hand, if the hardness of supporting roll 48 surpasses 90 °, then because of the hardness of supporting roll 48, parting tool 44 is beated on glass ribbon 14 when parting tool 44 is advanced, and is difficult to processing successive line of cut 46 on the surface of glass ribbon 14.In addition, the crack of line of cut is developed to more than the appropriate depth of sheet glass, and sheet glass is easy to fragmentation.
Thereby, be 50 ~ 90 ° through the hardness that makes supporting roll 48, can on the surface of glass ribbon 14, process more stable line of cut 46.
Fig. 5 is the side-view that between carrying roller 32A, 32B, has the carrying roller 32 of supporting roll 48, and Fig. 6 is the figure that the A-A' line from Fig. 5 is observed.
Like Fig. 5, shown in Figure 6, preferably in opposite directions the edge part a to the carrying roller 32A cut apart, 32B (to cut apart roller all the same to whole) carries out chamfer machining a.Likewise, preferably the edge part b at the roller both ends of supporting roll 48 is carried out chamfer machining.Through above-mentioned edge part a, b are carried out chamfer machining, can prevent on the back side of glass ribbon 14, to produce flaw because of the roller edge.
Fig. 7 is the side-view of the line of cut processing unit (plant) 70 of expression second embodiment.
This line of cut processing unit (plant) 70 is following devices; Promptly; The back side of the sheet glass below the thickness 0.7mm 74 is fixed on the thin-plate element (bracing member) 72 that does not move; Make parting tool 44 by advancing on the surface that is pressed in fixed sheet glass 74, thus on said surface the line of cut 46 of processing expectation.Thin-plate element 72 is also same with supporting roll 48 (with reference to Fig. 4 etc.), is the elastomerics that is formed by soft elastic material, and preferably its hardness is set at 50 ~ 90 °.In addition, the operating force that is applied on the sheet glass 74 of parting tool 44 is set at 1.6 ~ 8.0N too.
Thus, the line of cut of second embodiment processing loading amount 70 is also same with the line of cut processing unit (plant) 10 of first embodiment, can on the surface of the sheet glass below the thickness 0.7mm 74, process stable line of cut 46.
In addition; Material as supporting roll that satisfies said hardness 48 and thin-plate element 72; Can enumerate high nitrile resin (high nitrile resin), urethane, fluorine class rubber, neoprene; But material is not limited thereto, so long as soft elastic material gets final product, especially preferred hardness is 50 ~ 90 ° a material.
