The content of the invention

However, in the case of using above-mentioned manufacture device 1 or the manufacture sheet glass of manufacture device 2, there is following wanting The various problems for solving.

First problem is that the glass tape of the blank for becoming sheet glass easily becomes because acting on the external force etc. of the glass tape Shape.Therefore, when the glass tape after by shaping is carried downwards, there is the impact of the air-flow etc. produced because of the periphery of transportation route And cause the situation that raised side changes between the table back side of glass tape.Thus, there is glass tape to form line The situation that the state of the face depression of side is moved into liner agency, exists and is difficult to the difficult point to form line.

In view of the first technical task of the invention that such situation is completed is that it is possible to the glass for carrying the backward lower section of shaping Glass band is moved into the state for being maintained the shape for suitably forming line to liner agency.

Second Problem is, in the case where being used in manufacture device 2 to glass tape formation line, cannot also form auxiliary Helping between the male bend curved surface and glass tape that component has makes their bending completely the same.Therefore, certainly exist on glass tape Position from convex bending edema over the face.If the position that break bar floats into this, in the front of break bar fold is formed.Then, because being somebody's turn to do The formation of fold and the stress that produces are so that crack progressing, the unfavorable condition that there is glass desmorrhexis.

In view of the second technical task of the invention that such situation is completed is, the glass carried downward after to shaping When band forms line, the generation of the rupture in glass tape is prevented.

3rd problem is that glass tape not only produces the bending along its width, and also Jing often produces curved along its long side direction It is bent.Therefore, in the case where manufacture device 1 to be used in the cut-out that fractures of glass tape, because supporting mass is formed as cutting originally Go out the structure that portion remains even shape, therefore the detorsion along long side direction for resulting from cut-out portion is being by the supporting mass Cut-out portion is supported in the state of flat.Therefore, the unnecessary stress associated with correction bending is formed in the shape of cut-out portion State, causes the bending stress for performing the cut-out that fractures to be difficult to play a role because of the unnecessary stress, there is initiation glass The underproof shortcoming of cut-out of band.

In view of the 3rd technical task of the invention that such situation is completed is that it is possible to shaping the glass that backward lower section is carried Glass band reliably performs the cut-out that fractures.

4th problem is, when the cut-out portion of glass tape is set to lateral attitude, easily because of gravity under the cut-out portion Side produces sagging.The thickness of cut-out portion is thinner, and width dimensions are bigger, significantly produces this sagging.Therefore, inciting somebody to action In the case that manufacture device 1 is used in the cut-out that fractures of glass tape, because supporting mass is along the width two supports of cut-out portion The cut-out portion, therefore when cut-out portion is set to lateral attitude, its width central part can hang low because of gravity.As a result, The stress produced because this is sagging can be caused so that the damaged situation of cut-out portion.

In view of such situation and the 4th technical task of the invention that completes is, the glass carried to lower section after by shaping Glass band fractures when cutting off, it is to avoid the breakage of cut-out portion.

Means for solving the problems

The manufacture device of the glass plate involved in the present invention completed to solve above-mentioned first technical task possesses draws Line mechanism, the liner agency is passing through a surface side of glass tube down-drawing progressive forming and the glass tape carried downwards along width Form line, it is characterised in that the manufacture device of glass plate possesses deformation applying mechanism, the deformation applying mechanism make to move into The glass tape of liner agency is bent along width in the way of the projection of a surface side, deforms one side of the applying mechanism in glass tape Position between two positions separated from one another along width and two positions of another surface side of side has respectively There is the abutting member abutted with glass tape, using two abutting members of a surface side and the abutting member of another surface side in thickness side Clamp up glass tape.

According to such structure, there is two abutting members of a surface side and supporting for another surface side due to deforming applying mechanism Connection member, these abutting members clamping glass band in a thickness direction, therefore, it is possible to the glass tape for making to move into liner agency Bent in the way of the projection of a surface side in the width direction.That is, can be by glass tape being maintained the shape for suitably forming line State is moved into liner agency.

Preferably, on the basis of said structure, the manufacture device of glass plate possesses many along the transportation route of glass tape Individual deformation applying mechanism.

If it does, due to possessing multiple deformation applying mechanisms, therefore, it is possible to stably maintain glass tape in the width direction Bending.

Preferably, on the basis of said structure, two abutting members of a surface side and the abutting member of another surface side are made Abut with the non-effective portion for being present in width two ends of glass tape.

If it does, the effective portion for being present in width central part of glass tape can be avoided because of the abutting with abutting member And situation that is contaminated or scratching.

Preferably, on the basis of said structure, two abutting members of a surface side and the abutting member of another surface side with The width guide center of glass tape and symmetrically configure.

If it does, for the glass tape that move into liner agency, with width central authorities as boundary line can be made The position of side symmetrically bends with the position of opposite side.That is, can move into the glass tape of liner agency and be formed as being suitable to Form the shape of line.

Preferably, on the basis of said structure, two abutting members and the abutting member of another surface side of a surface side are Roller.

If it does, because abutting member is roller, therefore, it is possible to maintain the bending in the width direction and successfully of glass tape Move into liner agency.

Preferably, on the basis of said structure, liner agency has：Component is formed, is consisted of servo-actuated with glass tape Decline, and line is formed by moving along width in the one side of glass tape；And formed auxiliary part, its from Formation component of another surface side of glass tape in the glass tape supporting is mobile, and with the state synchronous with the formation component Move along width on another side, form component and form in the width direction curved of the auxiliary part along glass tape It is bent and move.

If it does, during initially form and be scoring to and complete, the formation only rule for forming glass tape is ongoing Position in a thickness direction by the bending in the width direction along glass tape the formation component of movement with formed auxiliary part The state of clamping.Therefore, the position for not forming line in the front of the formation component in movement is present in (is subsequently formed and draws The position of line) in, do not exist due to forming auxiliary part itself, therefore the position necessarily will not float from auxiliary part is formed. Thereby, it is possible to reliably avoid forming the situation of fold on the glass tape in front for forming component.As a result, being prevented from The stress that produces because of the formation of fold of generation so that crack progressing, so as to the situation of glass desmorrhexis.

Preferably, on the basis of said structure, forming component is advanced along width in the one side of glass tape Break bar, and formed auxiliary part be on another side along width advance break bar backing roll.

If it does, be break bar due to forming component, therefore, it is possible to be carried out at high speed the formation of line.Further, since being formed auxiliary Component is helped to be break bar backing roll, therefore, it is possible to stably support the break bar during (across glass tape supporting) advances using the roller.

Preferably, on the basis of said structure, a pair of niprolls are arranged respectively at the row of break bar and break bar backing roll Before and after entering direction, a pair of niprolls clamping glass band in a thickness direction, and it is suitable together with break bar and break bar backing roll The bending in the width direction of glass tape and advance.

If it does, in glass tape, from the position that the niproll in the front for being configured in break bar and break bar backing roll is clamped Put the position being configured between the position of the niproll at the rear of break bar and break bar backing roll clamping to be difficult to deform.And And, because break bar is difficult to be advanced on the position that deforms at this, rule therefore, it is possible to more accurately be formed to glass tape.In addition, by In being difficult to deform, even if in the case of so as to produce air-flow in the periphery of the transportation route of glass tape, it is also difficult to advance in break bar In position produce swing.Therefore, it is possible to avoid the generation of the situation for occurring from break bar to apply intensified pressure to the position local.By This, can more suitably prevent the generation of the rupture in glass tape.

Preferably, on the basis of said structure, the niproll advanced in the one side of glass tape in the rear of break bar has Have：The relatively small minor diameter part of diameter；And the diameter for rolling in one side and being respectively connected with the both sides of minor diameter part is relatively Big large-diameter portion, and niproll with minor diameter part across the line formed by break bar state advance.

If it does, for the niproll advanced in the one side of glass tape at the rear of break bar (below, is denoted as specific clamping Roller), the large-diameter portion being connected with the both sides of minor diameter part is rotated in the one side of glass tape, and is present between two large-diameter portions Minor diameter part with non-contacting state (from while the state that floats) advance.Because the minor diameter part is formed with crossing over by break bar Line state movement, therefore, as a result, can avoid specific niproll with rule contact, be prevented from specific folder Hold roller and press line while the generation of situation about advancing.Therefore, it is possible to avoid damaging glass tape because of the pressing of line.

Can also be on the basis of the manufacture device of above-mentioned glass plate, to replace in the rear of break bar the one of glass tape On face advance niproll, the manufacture device of glass plate equipped with guide reel, the guide reel between one side maintain have between The state of gap, moves along the bending in the width direction of glass tape.

If it does, being formed between guide reel and the one side of glass tape in the state of gap, guide reel movement.Therefore, Guide reel pressing line is prevented from, the damage of the caused glass tape because of the pressing of line can be avoided.It should be noted that Because guide reel is not contacted with the one side of glass tape, thus exist it is above-mentioned prevent glass tape deform decreased effectiveness risk, but Only form gap between guide reel and the one side of glass tape.Therefore, by the way that niproll is replaced with into guide reel, additionally it is possible to the greatest extent may be used It is avoided that the situation that the effect above weakens.

Preferably, on the basis of said structure, the diameter of break bar backing roll is bigger than the diameter of break bar.

If it does, because break bar is supported (support across glass tape) by the break bar backing roll bigger than break bar with diameter, therefore Line can be stably formed.

Preferably, on the basis of said structure, the manufacture device of glass plate possesses strip breaking mechanism, and the strip breaking mechanism passes through Decline while servo-actuated with glass tape, on one side so that the line forming portion for being formed with line is bent into along the long side direction of glass tape The raised mode in one surface side applies bending stress to forming portion of ruling, and so as to glass tape be fractureed cut-out, cuts out from the glass tape It is present in the cut-out portion of the lower section of line, there is strip breaking mechanism bending stress to apply component, the bending stress applies component and propping up Hold cut-out portion and maintain the cut-out portion in the state of the curved shape of the long side direction of glass tape, to rule forming portion apply Bending stress.

According to such structure, bending stress applies component by the cut-out portion supporting of glass tape not make it undeservedly deform And the state of natural shape (along the shape of the bending of the long side direction of glass tape) is maintained, therefore the deformation of the cut-out portion is led The unnecessary stress for causing is difficult to act on cut-out portion.Therefore, it is possible to avoid producing because of unnecessary stress so that for holding The bending stress of the capable cut-out that fractures is difficult to act on the situation of line forming portion.As a result, glass tape can be performed reliably The cut-out that fractures.

Preferably, on the basis of said structure, bending stress applies component to be had：Multiple supporting members, its supporting is cut Go out portion；And holding member, multiple supporting members are remained and are able to be slided along the thickness direction of cut-out portion by it.

If it does, remain and can slide along the thickness direction of cut-out portion because each supporting member is kept component, therefore Position of each supporting member on the thickness direction of cut-out portion can be easily adjusted.As a result, easily maintaining cut-out portion Natural shape (along the shape of the bending of the long side direction of glass tape).

Preferably, on the basis of said structure, multiple supporting members are multiple clamping elements, and the plurality of clamping element is along cutting The non-effective portion for being present in width two ends for going out portion arranges separated from one anotherly, and holds the non-effective portion.

If it does, because multiple supporting members are the non-effective portions for being present in width two ends of holding cut-out portion Clamping element, the effective portion for being present in width central part therefore, it is possible to avoid cut-out portion is subject to dirt because of the holding of clamping element Dye or situation about scratching.

Preferably, on the basis of said structure, strip breaking mechanism possesses lower end member to undertake, and the lower end member to undertake is in folding Support the bottom of cut-out portion during disconnected cut-out in the width direction.

Even if if it does, when cut-out is fractureed, cut-out portion is set to lateral attitude inclined relative to vertical, it is also possible to The situation for preventing the width central part (not being clamped the position that part holds) of cut-out portion from hanging low because of gravity.As a result, The stress produced because sagging can be avoided so that the generation of the damaged situation of cut-out portion.

Preferably, on the basis of said structure, lower end member to undertake supports from below cut-out portion along width One surface side of bottom.

In the case where lower end member to undertake supports in the width direction the lower end end surface of cut-out portion, exist because of bottom end The abutting of face and lower end member to undertake and cause the damaged misgivings of cut-out portion.If however, lower end member to undertake in the width direction from One surface side of lower section supporting bottom, then can effectively exclude such misgivings, and can stably support bottom.

Preferably, on the basis of said structure, lower end member to undertake is configured to for supporting in the width direction Move between the retreating position of the bearing position of the bottom of cut-out portion and the transportation route for deviateing glass tape.

If it does, by line forming portion apply bending stress when beyond, make lower end member to undertake to retreating position It is mobile, the unnecessary contact thus, it is possible to prevent cut-out portion and lower end member to undertake.

Preferably, on the basis of said structure, as retreating position, with the first retreating position and second position is kept out of the way Put, the first retreating position from bearing position to width on the outside of position away from, and the second retreating position be from The thickness direction that position is held along cut-out portion is positioned away from.

In the case where making lower end member to undertake move from bearing position to the first retreating position, and to the second retreating position Mobile situation is compared, even if the glass tape carried downwards swings in a thickness direction because of the impact of air-flow etc., also easily Avoid the unnecessary contact of glass tape and lower end member to undertake.On the other hand, make lower end member to undertake from bearing position to In the case that second retreating position is moved, compared with situation about moving to the first retreating position, easily by lower end member to undertake Action is suppressed to less.

In addition, the manufacture device tool of the glass plate involved in the present invention completed to solve above-mentioned second technical task Standby liner agency, the liner agency is while servo-actuated with the glass tape for passing through glass tube down-drawing progressive forming and carry downwards decline on one side Formed along width and rule, it is characterised in that liner agency has：Component is formed, it is by the one side of glass tape Move along width and form line；And auxiliary part is formed, it is from another surface side of glass tape across the glass tape Formation component during supporting is mobile, and be moved in the width direction on another side with the state synchronous with the formation component, shape Move along the bending in the width direction of glass tape into component and formation auxiliary part.

According to such structure, during initially form and be scoring to and complete, the shape only rule in glass tape is formed Into ongoing position in a thickness direction by the mobile formation component of the bending in the width direction along glass tape and formation The state of auxiliary part clamping.Therefore, the position that the line in the front of the formation component in movement is present in is not formed is (under connecing To form the position of line), do not exist due to forming auxiliary part itself, therefore the position will not necessarily occur from formation auxiliary The situation that component floats.Therefore, it is possible to reliably avoid, in the front for forming component, fold being formed on glass tape.Its result It is to be prevented from the stress produced because of the formation of fold so that crack progressing, the generation of the situation of glass desmorrhexis.

In addition, the manufacture device of the glass plate involved in the present invention completed to solve above-mentioned 3rd technical task is standby Strip breaking mechanism, the strip breaking mechanism while with carry by glass tube down-drawing progressive forming and downwards and be formed with line in the width direction Glass tape it is servo-actuated decline, while the line forming portion to being formed with line applies bending stress, cut so as to glass tape be fractureed It is disconnected, cut out the cut-out portion of the lower section for being present in line from the glass tape, it is characterised in that there is strip breaking mechanism bending stress to apply Component, the bending stress applies component in supporting cut-out portion and maintains the Curved of the long side direction along glass tape of the cut-out portion In the state of shape, to ruling, forming portion applies bending stress.

According to such structure, because bending stress applies component by the cut-out portion supporting of glass tape not make it undeservedly Deform and the state of the natural shape (along the shape of the bending of the long side direction of glass tape) of maintenance, therefore the change of the cut-out portion Shape caused by unnecessary stress will not act on cut-out portion.Therefore, it is possible to avoid because of unnecessary stress so that being used for Execution fracture cut-out bending stress be difficult to act on line forming portion situation generation.As a result, can reliably hold The cut-out that fractures of row glass tape.

In addition, the manufacture device tool of the glass plate involved in the present invention completed to solve above-mentioned 4th technical task Standby strip breaking mechanism, the strip breaking mechanism on one side with carry by glass tube down-drawing progressive forming and downwards and be formed with the width direction stroke The glass tape of line is servo-actuated to be declined, while the line forming portion to being formed with line applies bending stress, so as to glass tape be fractureed Cut-out, the cut-out portion of the lower section for being present in line is cut out from glass tape, and strip breaking mechanism has along the width two ends of cut-out portion Support the supporting mass of the cut-out portion, it is characterised in that strip breaking mechanism possesses lower end member to undertake, the lower end member to undertake is fractureing Support the bottom of cut-out portion during cut-out in the width direction.

According to such structure, even if when cut-out is fractureed, cut-out portion is set to inclination appearance inclined relative to vertical State, it is also possible to the situation for preventing the width central part (not being supported by the position of body supporting) of cut-out portion from hanging low because of gravity. As a result, the stress produced because sagging can be avoided so that the generation of the damaged situation of cut-out portion.

＜ second embodiments ＞

The manufacture device 1 of the glass plate involved by second embodiment of the present invention with involved by above-mentioned first embodiment And glass plate manufacture device 1 main difference part be in the rotation of arm main body 20ba, arm master can be changed as The position of the axis 29 of the center of rotation of body 20ba；Arm main body 20ba in rotation can also rotation.It should be noted that at this In second embodiment, it is also possible to configure barred body 40 and lower end bearing rod 39 identically with first embodiment.

As shown in figure 16, the manufacture device 1 of glass plate possesses：Rotating mechanism 48, it is used to make arm main body 20ba with along glass Rotation is carried out centered on the central axis 47 that width of the glass with G (X-X directions) extends；And travel mechanism 49, it passes through Move in the state of supporting rotating mechanism 48, so that the arm main body 20ba movement linked with rotating mechanism 48.Additionally, mobile Mechanism 49 possess for make arm main body 20ba along the first mobile travel mechanism 49a of the thickness direction (Z-Z directions) of glass tape G, And the second travel mechanism 49b for making arm main body 20ba move along the vertical direction.It should be noted that travel mechanism 49 sets It is placed in the floor 50 as stationary system.

Rotating mechanism 48 has what is rotated as axle center with central axis 47 in the state of linking with arm main body 20ba Axle portion 48a, the housing 48b for containing the first servo motor (omit diagram) linked with axle portion 48a and it is provided with for making The guiding piece 51 of housing 48b movements and via the supporting station 48c of the support housing 48b from below of guiding piece 51.

Axle portion 48a can utilize the positive and negative direction of rotation of the first servo motor control and rotary speed.In addition, axle portion 48a links with the central part on the longitudinally of arm main body 20ba, and arm main body 20ba can synchronously be entered with the rotation of axle portion 48a Row rotation.Also, along with the rotation of arm main body 20ba, bending stress apply component 20 it is overall centered on central axis 47 and Carry out rotation.Housing 48b can be moved along guiding piece 51 on the width (X-X directions) of glass tape G.Thus, pass through Matchingly move housing 48b with the size of the width dimensions of glass plate Gx (glass tape G), thus, it is possible to adjust via axle portion The position in the width direction of arm main body 20ba that 48a and housing 48b links.

Structure from the description above, when strip breaking mechanism 3 carries out snap action, by the first servo motor rotation side is controlled To and axle portion 48a of rotary speed rotated, arm main body 20ba carried out centered on central axis 47 synchronously therewith from Turn.Thus, the attitude of arm main body 20ba in snap action is controlled, so as to control the appearance that bending stress applies the entirety of component 20 State.The axis 29 for becoming center of rotation in addition, carry out rotation by arm main body 20ba, thus, it is possible to change arm main body 20ba Position.

Second travel mechanism 49b is with the ball-screw 52 by linking with the second servo motor (omitting diagram) along setting The movable body 49ba moved up and down in the guiding piece 54 of the framework 53 and supporting station 49bb of scaffold 53.

The supporting station 48c that movable body 49ba and rotating mechanism 48 possess links, and the second travel mechanism 49b can be via can Kinetoplast 49ba supports rotating mechanism 48.Further, since moving up and down along with movable body 49ba, links with movable body 49ba Supporting station 48c move up and down, therefore rotating mechanism 48 and with rotating mechanism 48 link arm main body 20ba move up and down.By This, bending stress applies the entirety of component 20 and synchronously moves along the vertical direction with moving up and down for movable body 49ba.

In order to when cut-out is fractureed apply bending stress, component 20 is servo-actuated with glass tape G to be declined, movable body 49ba energy It is enough to move downwards with glass tape G.Movable body 49ba translational speeds downward are controlled by the second servo motor.Thus, may be used Kinetoplast 49ba can be with mobile with the transporting velocity same speed of glass tape G (below, being denoted as base speed).Additionally, also can It is enough (below, to be denoted as slowing down with the speed (below, be denoted as accelerating velocity) or than base speed slow speed faster than base speed Speed) move downwards.

Structure from the description above, when strip breaking mechanism 3 carries out snap action, by the mobile speed of the second servo motor control The movable body 49ba of degree is moved downwards, and arm main body 20ba is moved downwards synchronously therewith.Now, the movement of movable body 49ba Speed switches to accelerating velocity or geard-down speed from base speed, so as to arm main body 20ba translational speed downward becomes Change, in the vertical direction, fulcrum rod 19 changes with the relative position relation of arm main body 20ba.Along with the change of the position relationship Change, component 20 is overall relatively to be moved along the vertical direction relative to fulcrum rod 19 to apply can bending stress.In addition, by changing Become the translational speed of arm main body 20ba, can relatively change the position of axis 29 in the vertical direction relative to fulcrum rod 19.

First travel mechanism 49a has movable body 49aa, and movable body 49aa with the 3rd servo motor by (saving sketch map Show) link ball-screw 55 along be arranged on thickness direction (Z-Z directions) of the guiding piece 57 of framework 56 in glass tape G move It is dynamic.

The supporting station 49bb that movable body 49aa and the second travel mechanism 49b possess links, and the first travel mechanism 49a can The second travel mechanism 49b is supported via movable body 49aa.In addition, by along with movable body 49aa towards thickness direction (Z-Z Direction) movement, with movable body 49aa link supporting station 49bb through-thickness movement, so as to the second travel mechanism 49b, The rotating mechanism 48 supported by the second travel mechanism 49b and the arm main body 20ba through-thickness linked with rotating mechanism 48 It is mobile.Thus, with the movement towards thickness direction of movable body 49aa synchronously, to apply component 20 overall in thickness for bending stress Side moves up.The moving direction and translational speed of the through-thickness of movable body 49aa is controlled by the 3rd servo motor.

Structure from the description above, when strip breaking mechanism 3 carries out snap action, by the 3rd servo motor movement side is controlled To and translational speed movable body 49aa movements, synchronously therewith through-thickness (Z-Z directions) is mobile for arm main body 20ba.It is logical Do so is crossed, the position on the thickness direction of arm main body 20ba in snap action is controlled, so as to control bending stress structure is applied Position on the thickness direction of the entirety of part 20.In addition, moved by making arm main body 20ba through-thickness, thus, it is possible in thickness Change the position of axis 29 on direction.

Above-mentioned rotating mechanism 48, the first travel mechanism 49a and the 49b actions of the second travel mechanism can be simultaneously made, Optionally can only make a mechanism in three or two mechanism actions.

In the present embodiment, at the same make rotating mechanism 48, the first travel mechanism 49a and the second travel mechanism 49b this Three's action.Thus, as shown in figure 17, the initial attitude for representing from solid line in arm main body 20ba is to fractureing that double dot dash line is represented Attitude change attitude when, be servo-actuated relative to glass tape G decline in the identical height and position of fulcrum rod 19, make axis 29 Position is along thickness direction (Z-Z directions) from the lateral back side Gb side shiftings of surface Ga.In the attitudes vibration of arm main body 20ba, Each mechanism of rotating mechanism 48, the first travel mechanism 49a and the second travel mechanism 49b carries out following action.

Thus rotating mechanism 48 makes arm by making the deasil rotation using central axis 47 as center of arm main body 20ba Main body 20ba gradually increases (the ＜ θ 2 of θ ＜ θ 1) relative to the angle of inclination of vertical line 30 from angle, θ.

In this, it is assumed that in the case where arm main body 20ba only carries out rotation, (1) exists along with rotation, the position of axis 29 From back side Gb lateral surface Ga side shiftings on thickness direction (Z-Z directions).Additionally, (2) are along with rotation, the position phase of axis 29 For fulcrum rod 19 is relatively moved downwards.Therefore, used by the first travel mechanism 49a and the second travel mechanism 49b In the movement for offsetting above-mentioned (1), (2), the position of axis 29 is made lateral from surface Ga with the identical height and position of fulcrum rod 19 The action of back side Gb side shiftings.

First travel mechanism 49a makes arm main body 20ba laterally carry on the back from surface Ga along the thickness direction (Z-Z directions) of glass tape G Face Gb side shiftings.Also, make the translational speed ratio of arm main body 20ba now lateral from back side Gb in above-mentioned (1) axis 29 The speed of surface Ga side shifting is fast.Thus, the movement of above-mentioned (1) is cancelled, and the position of axis 29 is in a thickness direction from table The lateral back side Gb side shiftings of face Ga.

Second travel mechanism 49b makes movable body 49ba with geard-down speed movement, so that arm main body 20ba is with fast with deceleration The equal speed of degree is moved downwards.In other words, the second travel mechanism 49b carry out for make the position of axis 29 relative to The action that point bar 19 is relatively moved upward.The movement of above-mentioned (2) is offset by the action, the position of axis 29 is upper and lower Side is maintained upward by and the identical height and position of fulcrum rod 19.

Above-mentioned action is carried out by rotating mechanism 48, the first travel mechanism 49a and the second travel mechanism 49b, so as to It is shown in solid in such as Figure 17, even if when the cut-out that fractures starts, because of the warpage along long side direction (Y-Y directions) of glass tape G So that line forming portion Gs floats from fulcrum rod 19, and in the cut-out that fractures, as shown in double dot dash line in the figure, forming portion Gs of ruling Float state be also repaired.

When the cut-out that fractures is completed and cuts out glass plate Gx from glass tape G, arm main body 20ba is using central axis 47 as in The heart and widdershins rotation.Thus, it is bent stress and applies the glass plate Gx of the supporting of component 20 using central axis 47 as center And rotate in the counterclockwise, form longitudinal attitude.Then, the glass plate Gx for forming the state of longitudinal attitude is shifted from strip breaking mechanism 3 To transfer mechanism 5.It should be noted that the rotation counterclockwise of arm main body 20ba overleaf side roller 21 is moved to from retreating position Perform after restriction site.

Hereinafter, modified embodiment of the present embodiment is illustrated.

In the present embodiment, on rotating mechanism 48 possesses axle portion 48a and the longitudinally of arm main body 20ba Centre portion links, but not limited to this.The position that axle portion 48a can also be made to deviate with the central part from longitudinally of arm main body 20ba Link is put, the location change for making the central axis 47 for becoming rotation center of arm main body 20ba is the positions different from present embodiment Put.

Here, the manufacture device of glass plate involved in the present invention is not limited by the knot of above-mentioned embodiment explanation Structure.In the manufacture device of the glass plate involved by above-mentioned embodiment, liner agency and strip breaking mechanism ground independent of one another Lower movement, but not limited to this, or both form as one and move up and down.That is, both liner agency and strip breaking mechanism Form as one, it is servo-actuated with glass tape to decline from the height and position that the height and position for initially forming line is completed to the cut-out that fractures And perform and fracture cut-out, and after the completion of fractureing and cutting off, both form as one, and are moved upward to initially forming line Height and position.

In addition, in the manufacture device of the glass plate involved by above-mentioned embodiment, being configured with injection for dispelling glass The gas injection nozzle of the gas of glass powder or the suction nozzle for attracting glass dust, but it is also possible to do not configure them.In such feelings Under condition, exist in order to prevent from causing glass because of the pressure of the gas of gas injection nozzle injection or the negative pressure of suction nozzle generation Band swings in a thickness direction and suppresses situation favourable for swing.Additionally, the swing of table back of the body both sides limits the back side in roller The swing of side limits roller and does not necessarily configure, it is also possible to which the only swing of allocation list surface side limits roller, makes the roller only auxiliary as fractureing Help roller and function.
