That is, when bending stress assigns component rotation, the cut-out portion for being supported on the state that the bending stress assigns component chases after The rotation of component is assigned with bending stress and be the center rotated from a surface side of glass tape towards another using score line forming portion Surface side rotates.On the other hand, in glass tape positioned at position and the cut-out portion of the position more against the top than score line on the contrary, along with Bending stress assign component rotation and using score line forming portion for rotation center from another surface side of glass tape towards on one side Side rotates.Therefore, it is impossible to score line forming portion is made effectively to be bent, so as to be difficult to make because being bent the bending stress generated effectively Act on score line forming portion.As a result, present situation be induce glass tape cut-out it is bad.

The technical task of the present invention completed in view of the foregoing is that it is possible to the glass by glass tube down-drawing progressive forming Glass band performs the cut-out that reliably fractures.

Solution

The present invention createed to solve the above-mentioned problems is the manufacturing device of glass plate, is had：Mechanism is delineated, It follows and is declined by glass tube down-drawing progressive forming and the glass tape carried downwards on one side, on one side along width direction in a surface side Form score line；And strip breaking mechanism, glass tape decline is followed on one side, on one side to being formed with the score line forming portion of score line Bending stress is assigned, thus glass tape fractures and cuts off and cut out from glass tape the cut-out portion for the lower section for being present in score line, folding There is breaking mechanism bending stress to assign component, which assigns component in the state of cut-out portion is supported from the one of glass tape Surface side is rotated towards another surface side, and score line forming portion is thus made to be bent in a manner that a surface side becomes protrusion, which is characterized in that Strip breaking mechanism has the auxiliary body that fractures, this fracture auxiliary body by from a face side bearing glass tape be located at than score line The position of position against the top is come the cut-out that assists fractureing.

According to structure as described above, in glass tape positioned at the position of the position more against the top than score line (hereinafter, table State as top position) it is broken off the cut-out that fractures that auxiliary body performs glass tape in the state of a face side bearing.Moreover, curved When transverse stress imparting component is rotated along with the execution for the cut-out that fractures, the cut-out portion for being present in the lower section of score line follows bending Stress assigns the rotation of component and is rotated from a surface side of glass tape towards another surface side.On the other hand, about top position, folding Disconnected auxiliary body prevents the position from assigning the rotation of component along with bending stress and rotated from another surface side towards a surface side.Cause This, can be such that score line forming portion is preferably bent, so as to which bending stress is made to effectively act on the score line forming portion. As a result, glass tape can be assuredly shut off.

On the basis of above-mentioned structure, it is preferable that roller is in the auxiliary body that fractures.

In this way, since roller is in the auxiliary body that fractures, can avoid due to the slip of fracture auxiliary body and glass tape Glass tape is caused to be scratched such state of affairs to occur.

On the basis of above-mentioned structure, it is preferable that strip breaking mechanism has in another surface side of glass tape swings limitation machine Structure, the swing limiting mechanism and fractures auxiliary body's coordinated and limits the thickness direction of the glass tape after the cutting out of cut-out portion Swing.

In such manner, it is possible to it is cut out by the coordinated for the two mechanisms of auxiliary body and swing limiting mechanism that fracture to limit Portion be cut out after glass tape thickness direction on swing.Thereby, it is possible to avoid glass tape and the transport road along glass tape Diameter and the contacts such as machinery for being configured.As a result, it is the state of affairs as glass tape damage caused by cause to contact that can prevent Occur.

On the basis of above-mentioned structure, it is preferable that swing limiting mechanism is roller.

In this way, it is roller due to swinging limiting mechanism, when can avoid the slip because swinging limiting mechanism and glass tape Glass tape is caused to be scratched such state of affairs to occur.

On the basis of above-mentioned structure, it is preferable that swing limiting mechanism and be configured to, can be used for close to glass tape It limits the restriction site swung and is used between the two positions of the retreating position kept out of the way move, and form far from glass tape To be moved after the cutting out of cut-out portion from retreating position to restriction site.

In this way, become the knot moved after the cutting out of cut-out portion from retreating position to restriction site due to swinging limiting mechanism Structure, therefore (cut-out portion cut out before) can be such that swing limiting mechanism treats in advance in the implementation procedure for fractureing cut-out of glass tape Machine is in the retreating position far from glass tape.Therefore, it is possible to avoid swing limiting mechanism in the implementation procedure for the cut-out that fractures with glass Glass band contacts and the state of affairs as interfering the bending of score line forming portion occurs.

On the basis of above-mentioned structure, it is preferable that in the swing limiting mechanism and glass tape for being moved to restriction site Gap is formed between another side.

In this way, due to being configured to be formed between the swing limiting mechanism and the another side of glass tape for being moved to restriction site There is gap, therefore can prevent from fractureing and auxiliary body and be moved to the swing limiting mechanism of restriction site and clamp in a thickness direction Glass tape.Thereby, it is possible to while the swing for limiting glass tape, avoid using two mechanisms undeservedly to glass tape working tension Deng and the state of affairs as causing harmful effect to the forming of the glass tape based on glass tube down-drawing generates.

On the basis of above-mentioned structure, it is preferable that the auxiliary body that fractures limits machine with the swing for being moved to restriction site Structure is configured to clip the non-effective portion for being present in width direction both ends of glass tape.

In this way, when fractureing auxiliary body and swinging the swing of limiting mechanism limitation glass tape, glass tape can be avoided It is present in effective portion (later as the position of product) of width direction central portion and auxiliary body and the swing limitation machine of fractureing Structure contacts.Therefore, it is possible to prevent from be thus effective portion of glass tape being caused to be contaminated to contact.

On the basis of above-mentioned structure, it is preferable that the auxiliary body that fractures limits with the swing for being moved to restriction site Mechanism processed is configured to clip the lower end of the glass tape after the cutting out of cut-out portion.

It auxiliary body and is moved to the two mechanisms of the swing limiting mechanism of restriction site in this way, fractureing and is present in and cuts Go out the identical height and position in the lower end of the glass tape after the cutting out of portion.Therefore, it is possible to preferably limit the amplitude of swing maximum Lower end swing.Moreover, the swing by limiting lower end, can be effectively prevented the swing of glass tape entirety.

On the basis of above-mentioned structure, it is preferable that the auxiliary body that fractures is located at the position than delineation mechanism on the lower.

In this way, since the auxiliary body that fractures is located at the position than delineation mechanism on the lower, the auxiliary body that fractures becomes Relative to the score line that delineation mechanism is formed positioned at the state in the downstream side of the transport path of glass tape.That is, delineation mechanism The score line formed moves after it is formed along with the carrying of glass tape to the auxiliary body side that fractures.Therefore, upper portion Position is also to the auxiliary body's side movement that fractures in the same manner as score line.Therefore, it is moved as long as the auxiliary body that fractures supports to itself side The top position to come over, therefore the auxiliary for the cut-out that can be effectively carried out fractureing.

As shown in arrow E-E in Fig. 1, the manufacturing device 1 of above-mentioned glass plate has delineation mechanism 2, the delineation mechanism 2 Formed while following glass tape G and declining the formation action of score line S and after score line S is formed upward The return action of return.In addition, as shown in arrow F-F in Fig. 1, under than transport path of the delineation mechanism 2 by glass tape G The position of trip side has strip breaking mechanism 3, which carries out performing the cut-out that fractures while following glass tape G and declining Snap action and the homing action resetted upward after the cut-out that fractures is performed.It delineates mechanism 2 and strip breaking mechanism 3 can Move up and down independently of each other, delineation mechanism 2 using in Fig. 1 by solid line represent position as upper end, will be by double dot dash line table The position shown is moved up and down as lower end.On the other hand, strip breaking mechanism 3 will be made by the position that double dot dash line represents in Fig. 1 It is moved up and down for upper end, using by the position that solid line represents as lower end.

In addition, the manufacturing device 1 of glass plate is in the position than delineation mechanism 2 by the upstream side of the transport path of glass tape G Has deformation imparting mechanism 4, the glass tape G which makes to move in delineation mechanism 2 is with along width direction (X-X side To) surface Ga side is made to be bent as the mode of protrusion.In addition, have to receive holding by the cut-out that fractures from strip breaking mechanism 3 Row and the glass plate Gx that cuts out and by the transfer mechanism 5 of its downstream process transfer.

Here, contain the manufacturing process in product glass plate at the width direction both ends of the glass tape shaped by glass tube down-drawing In the non-effective portion that is removed.In addition, the scrap portion that thickness is larger compared with other positions is contained in non-effective portion.It is said in following In bright, " non-effective portion Gu " is expressed as in the case of the position in addition to scrap portion in representing non-effective portion, is representing useless Material is expressed as " scrap portion Gm " in the case of portion.

Hereinafter, the details for deforming imparting mechanism 4 are illustrated.

Deformation imparting mechanism 4 makes surface Ga to imitate glass tape G original along the bending of width direction (X-X directions) The mode that side becomes protrusion is bent glass tape G.As shown in Fig. 2, transport road of the deformation imparting mechanism 4 along glass tape G Diameter is configured with two, this two deformation imparting mechanisms 4 have identical structure.As shown in figure 3, two deformation imparting mechanisms 4 is each A deformation imparting mechanism 4 is in the surface Ga side of glass tape G two positions separated from each other, overleaf Gb sides position in the width direction The bearing as abutting member abutted with glass tape G is respectively provided in two mutual positions at two aforementioned positions Roller 4a.Two backing roll 4a of surface Ga side and two backing roll 4a of back side Gb sides are with the width direction center Gc of glass tape G On the basis of and be symmetrically configured, and in a manner that the non-effective portion Gu at the width direction both ends with being present in glass tape G is abutted Configuration.Moreover, it is sandwiched on thickness direction (Z-Z directions) using the backing roll 4a of surface Ga side and the backing roll 4a of back side Gb sides Glass tape G.It should be noted that the backing roll 4a of surface Ga side and the backing roll 4a of back side Gb sides are free roll.

Each backing roll 4a links respectively via ball-screw (illustration omitted) and with cylinder 4b, and each cylinder 4b is respectively arranged in In the frame 6 that the surface Ga side of glass tape G and back side Gb sides are configured.Moreover, each backing roll 4a is by adjusting in each cylinder 4b The increase and decrease of pressure and can be mobile along the thickness direction (Z-Z directions) of glass tape G as shown in arrow H-H in figure 3, and by Ball-screw and be moved forward and backward, thus allow for the micro-adjustment of the position along thickness direction.As a result, by making surface Ga side Backing roll 4a and back side Gb sides backing roll 4a it is mobile and adjust the position of the thickness direction along glass tape G of each backing roll 4a It puts, the bending (curvature) along width direction (X-X directions) of glass tape G can be made arbitrarily to change.

Here, when the backing roll 4a of the backing roll 4a by surface Ga side and back side Gb sides sandwich glass tape G, due to making glass Glass band G is reliably bent along width direction (X-X directions), therefore as shown in figure 4, it is preferred that bearing by adjacent surface Ga side The lap J of roller 4a and the backing roll 4a of back side Gb sides are (to situations of the two backing roll 4a from the direction along its rotary shaft Under lap) be set as in the range of 3mm~100mm.Additionally, it is preferred that by the backing roll 4a of adjacent surface Ga side and back side Gb The separating distance K of the backing roll 4a of side be set as (along the separating distance on the direction of the rotary shaft of two backing roll 4a) 30mm~ In the range of 500mm.Further, since by glass tape G to delineation in the state of steadily maintaining along the bending of width direction Mechanism 2 moves in, therefore as shown in Fig. 2, it is preferred that by the height and position of the formation of score line S since being delineated mechanism 2 to closest Separating distance L until delineating the deformation imparting mechanism 4 of mechanism 2 is set as (along the separating distance of the transport path of glass tape G) In the range of 100mm~1500mm.

Structure from the description above, the glass tape G moved in delineation mechanism 2 become with along width direction (X-X side To) surface Ga side is made to become the state that the mode of protrusion is bent.In addition, in glass tape G, using width direction center Gc as point The position of the side on boundary and the position of opposite side become the state being symmetrically bent.

Hereinafter, the variation for deforming imparting mechanism 4 is illustrated.

In the present embodiment, backing roll 4a is used as the abutting member abutted with glass tape G, but be not limited to This.For example, it is also possible to it is configured instead of each backing roll 4a on the length direction (Y-Y directions) of glass tape G in the conveying of strip Band (conveying direction is from top to lower section).The length direction along glass tape G is configured alternatively, it is also possible to replace each backing roll 4a Pole of extension etc..

Hereinafter, the details for delineating mechanism 2 are illustrated.

As shown in figs.5 and 6, delineation mechanism 2 has：By in the surface Ga of glass tape G along width direction (X- X-direction) advance and formed score line S as formed component cutting wheel 2a；Row is supported from back side Gb sides across glass tape G It cutting wheel 2a in and is advanced using in the state synchronous with cutting wheel 2a overleaf Gb along width direction auxiliary as being formed Help the wheel backing roll 2b of component.The diameter D2 for taking turns backing roll 2b is more than the diameter D1 of cutting wheel 2a.In addition, in cutting wheel 2a and The front and rear of the direction of travel M of wheel backing roll 2b is each configured with while glass tape G through-thickness (Z-Z directions) is clamped With a pair of of the niproll 7 advanced together with cutting wheel 2a and wheel backing roll 2b along width direction.Moreover, cutting wheel 2a, wheel branch Runner 2b and each niproll 7 can imitate advancing along the bending of width direction for glass tape G.It should be noted that wheel Backing roll 2b and each niproll 7 are free roll.

It is in multiple niprolls 7, the rear of cutting wheel 2a and advance in the surface Ga of glass tape G niproll 7 (with Under, it is expressed as specific niproll 7a) there is the shape different from other niprolls 7.As shown in fig. 7,7 shape of other niprolls As cylindric.On the other hand, specific niproll 7a has：The relatively small small diameter portion 7aa of diameter；And glass tape G's It is rolled in surface Ga and the large-diameter portion 7ab relatively large with diameter that the both sides of small diameter portion 7aa are respectively connected with.Moreover, specific clamping Roller 7a is configured to advance across the state of the score line S formed by cutting wheel 2a with small diameter portion 7aa.As a result, in specific niproll In the traveling process of 7a, the only large-diameter portion 7ab in small diameter portion 7aa and large-diameter portion 7ab becomes what is contacted with the surface Ga of glass tape G State.

Cutting wheel 2a and advance in surface Ga two niprolls 7 (hereinafter, by these unified presentations be surface advance 8) group links with conveyer 12 as shown in Figure 1, which has the driving wheel for driving servo motor as power source 9th, driven wheel 10, be wound in the band 11 of driving wheel 9 and driven wheel 10.The conveyer 12 is by width direction (the X-X side of glass tape G To) conveying direction is set as, and the direction that the conveyer 12 can turn round band 11 is opposite.Moreover, the rotation along with driving wheel 9 Then band 11 is turned round, thus surface traveling group 8 is moved along the width direction of glass tape G.

As shown in figure 5, the cutting wheel 2a and two niprolls 7 of composition surface traveling group 8 distinguish by with these components Connection each ball-screw 12a and with conveyer 12 link in the state of also can be along the thickness direction (Z-Z of glass tape G Direction) it is mobile.Each respective drivings of ball-screw 12a are controlled by servo mechanism (illustration omitted).Moreover, surface traveling group 8 is logical It crosses and is moved in the moving process along the width direction of glass tape G (X-X directions) also along thickness direction, thus imitate glass Advancing along the bending of width direction with G.

It is being accommodated in its shell 13 as shown in Figure 1, conveyer 12 is configured.Moreover, as shown in Fig. 2, along with shell 13 It is moved up and down by the ball-screw 15 linked with servo motor 14 along the guiding piece 16 for being set to frame 6, conveyer 12 It moves up and down.

Equally, as shown in figure 5, taking turns backing roll 2b and two niprolls 7 overleaf advanced on Gb (hereinafter, by them It is referred to as countermarch group 17) connect respectively with ball-screw 18a (ball-screw with the structure identical with ball-screw 12a) Knot, and link as shown in Figure 9 with conveyer 18, which has the structure identical with conveyer 12 and across glass tape G and be opposed to be configured with conveyer 12.

Structure from the description above, delineate mechanism 2 carry out forming action when, two conveyers 12,18 with glass tape G The identical speed of transporting velocity and glass tape G followed with the state being mutually in step in surface Ga side and back side Gb sides decline.And And during two conveyers 12,18 follow glass tape G declines, surface traveling group 8 and countermarch group 17 imitate glass The bending along width direction (X-X directions) with G and advance.It should be noted that it in the present embodiment, is advanced with surface The mode that group 8 and countermarch group 17 imitate above-mentioned deformation imparting mechanism 4 to assign the bending of glass tape G and advance is controlled System.In addition, in glass tape G, so as to (be applied with friendship in figure 6 by the position that surface traveling group 8 and countermarch group 17 clip Pitch the position of hachure) the flat mode of shape control opposite position between cutting wheel 2a, wheel backing roll 2b and each niproll 7 Put relationship.When formation of the score line S to glass tape G is completed, the decline that two conveyers 12,18 follow glass tape G stops.

On the other hand, when delineating the progress return action of mechanism 2, two conveyers 12,18 are in surface Ga side and back side Gb The state that side is mutually in step is moved upward.Moreover, during two conveyers 12,18 are moved upward, band 11 is with forming Direction in action is oppositely turned round, surface traveling group 8 and countermarch group 17 along glass tape G width direction (X-X side To) and oppositely moved with the direction in formation action.At this point, in the ball-screw 12a and ball that are controlled by servo mechanism Under the driving of leading screw 18a, surface traveling group 8 and countermarch group 17 along the thickness direction (Z-Z directions) of glass tape and with Mode far from glass tape G moves, and thus two traveling groups 8,17 are controlled as in return action not contacting with glass tape G. Moreover, in height and position of two conveyers 12,18 back to the formation for starting score line S (the score line S that next time is formed), stop Only their movements upward.

Hereinafter, the variation for delineating mechanism 2 is illustrated.

In the present embodiment, cutting wheel 2a is used, but be not limited to as the formation component for forming score line S This, as long as score line S can be formed by being moved in the surface Ga of glass tape G, can also just use other components.It enumerates If an example, as component is formed, acicular formation blade etc. can also be used.In addition, about auxiliary part is formed, it can also Using the component other than wheel backing roll 2b, as long as formation component on the move can be supported across glass tape G.

In addition, in the present embodiment, surface traveling group 8 and back side traveling group 17 is made to imitate deformation imparting mechanism 4 It assigns the bending of glass tape G and advances, but it's not limited to that.For example, it is also possible to utilize the width direction along glass tape G Multiple displacement sensors of (X-X directions) arrangement will move in the bending for the glass tape G for delineating mechanism 2 to detect, and be based on Testing result makes surface traveling group 8 and back side traveling group 17 imitate advancing along the bending of width direction for glass tape G. So, even if in the case where glass tape G has and rises and falls, score line S can be also reliably formed.

In addition, in the present embodiment, so as to be put down by the shape at position that surface traveling group 8 and countermarch group 17 clip Smooth mode controls the relative position relation between cutting wheel 2a, wheel backing roll 2b and each niproll 7.However, do not limit to In this, cutting wheel 2a, wheel backing roll 2b can also be controlled in a manner of the bending at position for maintaining to be clipped by two traveling groups 8,17 And the relative position relation between each niproll 7.

Alternatively, it is also possible to replace the specific niproll 7a used in the present embodiment, what is formed from cutting wheel 2a Score line S is upward or at the height and position of lower section offset, configuration imitate glass tape G along width direction (X-X directions) Bending and the niproll 7 advanced in surface Ga.In addition it is also possible to instead of each niproll 7 used in the present embodiment, Configuration maintenance between glass tape G imitates being moved along the bending of width direction for glass tape G in the state of having gap Guide reel.In this case, in both the surface Ga side of glass tape G and back side Gb sides opposed pairs guide reel, control Relative position relation so that the mutual distance of the two is slightly longer than the thickness of glass tape G.Alternatively, it is also possible to only The niproll 7 of a part in multiple niprolls 7 is replaced with into guide reel.In the case where carrying out replacement as described above, such as It, preferably will be in the rear of cutting wheel 2a and (the specific niproll of niproll 7 advanced in the surface Ga of glass tape G shown in Fig. 8 7a) replace with guide reel 7x.It should be noted that guide reel 7x is also free roll.Here, it is formed in guide reel 7x and glass The width AA in the gap between the surface Ga with G is preferably set in the range of 0.5mm~5mm.

In addition, in the present embodiment, when delineating the progress return action of mechanism 2, two conveyers 12,18 are in surface Ga The state that side and back side Gb sides are mutually in step is moved upward, and however, it is not limited to this, can also distinguish two conveyers 12,18 It is moved upward.

Hereinafter, the details of strip breaking mechanism 3 are illustrated.

As shown in Figure 10, strip breaking mechanism 3 has：It is abutted from back side Gb sides with score line forming portion Gs and becomes the cut-out that fractures Fulcrum the fulcrum rod 19 as fulcrum member；It is present in the state of the glass plate Gx of the lower section of score line S with bearing from table Face Ga sides rotate towards back side Gb sides and score line forming portion Gs bendings are made to assign component to assign the bending stress of bending stress 20；For limiting the work of the swing of the thickness direction (Z-Z directions) of the glass tape G of (glass plate Gx cut out after) after the cut-out that fractures Swing to swing limiting mechanism limits roller 21；Spray the gas for blowing the winged glass dust Gk along with fracture cut-out and generation The gas nozzle 22 of 22a；And the suction nozzle 23 for attracting glass dust Gk.It should be noted that the composition of these strip breaking mechanisms 3 The swing limitation roller 21 for being located at the top in element is located at the position than delineation mechanism 3 on the lower.

When strip breaking mechanism 3 carries out snap action, mobile speed is controlled by the second servo motor for structure from the description above The movable body 49ba of degree is moved downwards, and arm body 20ba is synchronously moved downwards with this.At this point, the movement of movable body 49ba Speed is switched to accelerating velocity or geard-down speed from base speed, and thus the movement speeds of arm body 20ba downwards become Change, the relative position relations of fulcrum rod 19 and arm body 20ba in the up-down direction change.Along with the position relationship Variation, can assigning bending stress, component 20 is whole to be moved along the vertical direction relative to fulcrum rod 19.In addition, pass through arm master The movement speed of body 20ba changes, and can vertically change the position of axis 29 relative to fulcrum rod 19.

There is first movement mechanism 49a movable body 49aa, movable body 49aa (to save sketch map by with third servo motor Show) connection ball-screw 55 and along the guiding piece 57 set on frame 56 glass tape G thickness direction (Z-Z directions) Upper movement.

The supporting table 49bb connections that movable body 49aa and the second mobile mechanism 49b have, first movement mechanism 49a The second mobile mechanism 49b can be supported via movable body 49aa.In addition, along with movable body 49aa along thickness direction (Z-Z Direction) movement, with the movable body 49aa connection supporting table 49bb through-thickness moved, thus second movement Mechanism 49b, the rotating mechanism 48 for being supported on the second mobile mechanism 49b and the arm body 20ba edges linked with rotating mechanism 48 Thickness direction is moved.Becoming bending stress as a result, assigns component 20 the whole shifting with movable body 49aa along thickness direction The structure of dynamic synchronously through-thickness movement.Movable body 49aa along thickness direction moving direction and movement speed by Third servo motor controls.

When strip breaking mechanism 3 carries out snap action, movement side is controlled by third servo motor for structure from the description above To and the movable body 49aa of movement speed moved, arm body 20ba with this synchronously through-thickness (Z-Z directions) into Row movement.Thus, which the position on the thickness direction of arm body 20ba in snap action is controlled, bending stress assigns Position on the whole thickness direction of component 20 is controlled.In addition, it is moved by arm body 20ba through-thickness, energy Enough positions for changing axis 29 in a thickness direction.

For above-mentioned rotating mechanism 48, first movement mechanism 49a and the second mobile mechanism 49b, this can be made Three acts simultaneously, and is acted selectively only one mechanism or Jin Liangge mechanisms in this three.

In the present embodiment, make rotating mechanism 48, first movement mechanism 49a and second mobile mechanism 49b this three It acts simultaneously.As a result, as shown in figure 17, in arm body 20ba from the initial attitude that is represented from solid line to being represented by double dot dash line When the posture that fractures carries out attitudes vibration, with following at the identical height and position of fulcrum rod 19 during glass tape G declines, make It is moved along thickness direction (Z-Z directions) from the lateral back side Gb sides of surface Ga the position of axis 29.It is carried out in arm body 20ba During attitudes vibration, each mechanism progress of rotating mechanism 48, first movement mechanism 49a and the second mobile mechanism 49b is following such Action.

Rotating mechanism 48 makes arm body 20ba thus make arm body centered on central axis 47 and along rotation clockwise 20ba becomes larger (1 ＜ θ 2 of θ ＜ θ) relative to the angle of inclination of plumb line 30 from angle, θ.

Here, in the case of assuming that arm body 20ba only carries out rotation, (1) is along with the position for transferring to lead to axis 29 certainly It puts and is moved on thickness direction (Z-Z directions) from back side Gb lateral surface Ga sides.In addition, (2) are along with oneself then lead to axis It is moved downwards relative to fulcrum rod 19 29 position.Therefore, first movement mechanism 49a and the second mobile mechanism 49b into The following action of row, which is used to offset the movement of (1), (2), so as to make the position of axis 29 in the height identical with fulcrum rod 19 Position is spent from the lateral back side Gb sides movement of surface Ga.

First movement mechanism 49a makes arm body 20ba along the thickness direction (Z-Z directions) of glass tape G and from surface Ga side Rearwardly Gb sides are moved.Moreover, make the movement speed of arm body 20ba at this time than the axis 29 in above-mentioned (1) from the back side The speed of Gb lateral surface Ga sides movement is fast.The movement of above-mentioned (1) is cancelled as a result, and the position of axis 29 is in thickness direction On from the movement of surface Ga lateral back side Gb sides.

Second mobile mechanism 49b makes movable body 49ba be moved with geard-down speed, thus makes arm body 20ba with fast with deceleration Equal speed is spent to move downwards.That is, the second mobile mechanism 49b carries out position for making axis 29 relative to fulcrum rod 19 And the action being moved upward.According to the action, the movement of above-mentioned (2) is cancelled, and the position of axis 29 is in the up-down direction It is maintained the height and position identical with fulcrum rod 19.

Above-mentioned action is carried out by rotating mechanism 48, first movement mechanism 49a and the second mobile mechanism 49b, so as to As in Figure 17 as shown in solid, at the beginning of the cut-out that fractures, even if alongst (the Y-Y side with glass tape G To) warpage be thus score line forming portion Gs is caused to float from fulcrum rod 19, also can in the cutting-off process that fractures as scheme 17 correct the float state of score line forming portion Gs like that as shown in double dot dash line.

When cutting out glass plate Gx from glass tape G when fractureing cut-out completion, arm body 20ba is centered on central axis 47 And along rotation counterclockwise.Be supported on as a result, bending stress assign component 20 glass plate Gx centered on central axis 47 edge Rotation counterclockwise, so as to as longitudinal posture.Moreover, as longitudinal posture state glass plate Gx from strip breaking mechanism 3 to shifting Mechanism 5 is sent to join.It should be noted that overleaf side roller 21 is moved to from retreating position for the rotation counterclockwise of arm body 20ba It is performed after restriction site.

Hereinafter, modified embodiment of the present embodiment is illustrated.

In the present embodiment, on the length direction of the axle portion 48a that rotating mechanism 48 has and arm body 20ba Centre portion links, but it's not limited to that.Slave central portion on the length direction of axle portion 48a and arm body 20ba can also be deviated Position connection, the position of the central axis 47 as the center of the rotation of arm body 20ba is changed to present embodiment not Same position.
