The shearing device 10 of glass plate as shown in Figure 2 possesses the cut-out roller 16 cut off by ribbon glass plate 12 along cutting line 14.And, possessing by many rollers 18,18 across cut-out roller 16 below the upstream side in the carrying direction of ribbon glass plate 12 ... the roller path of composition, and possessing by many rollers 20,20 below the downstream in described carrying direction ... the roller path of composition.Further, above-mentioned roller 18,20 is arranged in the way of upper surface level becomes sustained height.
It addition, in order to easily cut off ribbon glass plate 12, in the upstream side pressing roller 22 configured above in the described carrying direction of cut-out roller 16, and in the downstream pressing roller 24 configured above in described carrying direction.Pressing roller 22,24 is arranged on symmetric position relative to cut-out roller 16, pressing roller 22 sandwiches ribbon glass plate 12 together with roller 18 up and down and keeps, and the rectangular glass about 26 after the ribbon glass plate 12 being about to before cutting off and just cut-out is sandwiched together with roller 20 and keeps by pressing roller 24.
It should be noted that in FIG, roller 18,20 is omitted in order to explicitly indicate that the allocation position of cut-out roller 16.And, pressing roller 22,24 as Fig. 1 and the orthogonal direction, carrying direction of ribbon glass plate 12 there is the interval of regulation and be respectively configured multiple stage (being 5 in FIG).And, ribbon glass plate 12 Surface Machining thereon has cutting line 14, and the machine direction of this cutting line 14 is the direction orthogonal with described carrying direction.The material of pressing roller is not particularly limited, but preferably will not damage the material of banding glass plate 12 and rectangular glass 26.
Fig. 3 A is turned off using the axonometric chart of roller 16, Fig. 3 B to be turned off with the side view of roller 16.And, in these figures, the direction of rotation of cut-out roller 16 is represented by arrow B.
Cut-out roller 16 possesses the projection of lateral section rectangle (the first projection) 28 at roller surface 16A.This projection 28 is parallel with the rotating shaft 17 of cut-out roller 16 and arranges in the length-over of cut-out roller 16.The cutting line 14 of the cut-out roller 16 ribbon glass plate 12 in carrying arrives and is driven and rotate the opportunity of cut-out roller 16, ribbon glass plate 12, by the lower surface jack-up as shown in Figure 4 of the ribbon glass plate 12 of the lower section of the cutting line 14 of arrival, is thus cut off by projection 28 along cutting line 14.The shape of the first projection 28 is not defined to lateral section rectangle, it is also possible to be lateral section curved shape.And, as the material of the first projection 28, for comprising the hardened member of the metal such as ferrum, steel, it is preferable that be installed on the mode of cut-out roller 16 in removable mode, for instance chimeric mode, bonding mode.
Specifically, ribbon glass plate 12 is by roller 18,18 ... carry towards cut-out roller 16, and, when cutting line 14 arrives the front of cut-out roller 16, cut-out roller 16 starts to rotate.Utilization clearly obtains the projection 28 of cut-out roller 16 and the method for the position relationship of cutting line 14, for instance with contact glass sheet while the method for the enumerator etc. of the carrying amount of measurement glass plate provides the instruction rotating beginning of cut-out roller 16.Also, it is preferred that make the circumferential speed of cut-out roller 16 consistent with the circumferential speed of roller 18.When cut-out roller 16 rotates, by projection 28 by the lower surface jack-up upward of the ribbon glass plate 12 of the lower section of the cutting line 14 of ribbon glass plate 12, ribbon glass plate 12 cutting line 14 near portion produce bending moment.Further, along with the increase that the jack-up of the ribbon glass plate 12 of projection 28 generation is measured, the tensile stress on the surface of ribbon glass plate 12 increases.Further, when the tensile stress that the breaking-down point become with the crackle under cutting line 14 has is corresponding, this CrackGrowth and ribbon glass plate 12 are cut off along cutting line 14, the rectangular glass 26 of the length of regulation are cut from ribbon glass plate 12.Cut-out roller 16 continues further to rotate after cut-out completes, and stops the rotation when next smooth roller surface 16A arrives the lower surface of ribbon glass plate 12, the standby arrival to next cutting line 14.
It should be noted that when rectangular glass 26 being cut from ribbon glass plate 12, at the roller 20,20 of Fig. 1 that cut-out configures with the downstream of roller 16 ... be controlled so as to carry out the speedup of stipulated time than the faster rotational speed of roller 18 in the way of rotating.Thus, continue the rectangular glass 26,26 cut ... when having separated the interval of regulation, by towards roller 20,20 ... the plate portion (not shown) that selects in downstream carry, it is possible to what prevent rectangular glass 26 contact each other and rectangular glass 26 and ribbon glass plate 12 contacts the breakage caused.It should be noted that the scope of stipulated time is not particularly limited, as long as the time of the state at the interval of regulation can be formed as separating.
But, as shown in Fig. 3 A, Fig. 3 B and Fig. 4, ratio projection 28 at cut-out roller 16 more leans on the surface of direction of rotation upstream side to be conformed with (the second projection) 30, and this projection 30 falls to roller surface 16A for preventing the carrying direction leading section 12A of the ribbon glass plate 12 of carrying direction upstream side.
It follows that the effect of cut-out roller 16 is described based on Fig. 4.
The lower surface of the lower section of the cutting line 14 of the ribbon glass plate 12 in carrying along arrow A direction is by raised 28 jack-up of the cut-out roller 16 rotated to arrow B direction, and ribbon glass plate 12 is cut off along cutting line 14.The projection 30 that carrying leading section, the direction 12A of the ribbon glass plate 12 after cut-out is arranged with the direction of rotation stream side surface of the projection 28 at cut-out roller 16 contacts, when preventing from falling to roller surface 16A by cut-out roller 16.
Thus, the shearing device 10 according to the glass plate of embodiment, it is possible to prevent from ribbon glass plate 12 is just cutting off breakage that occur afterwards, carrying direction upstream side ribbon glass plate 12 carrying leading section, direction 12A.
Projection 30 is the lateral section fan-shaped component of the curved surface 30A from the upper surface 28A of projection 28 towards roller surface 16A as shown in Fig. 3 A, Fig. 3 B with arc-shaped.
As long as projection 30 has carrying leading section, the direction 12A of the ribbon glass plate 12 preventing carrying direction upstream side to the roller surface 16A function fallen, it does not have be defined to the projection 30 of the lateral section fan-shaped shown in Fig. 3 A, Fig. 3 B.That is, as long as there is carrying leading section, the direction 12A avoiding the ribbon glass plate 12 carrying direction upstream side when by cut-out roller 16 to the roller surface 16A of cut-out roller 16 function fallen.
Hereinafter, the variation of cut-out roller is described.
Fig. 5 A indicates that the axonometric chart of the first variation of cut-out roller 34, and Fig. 5 B is the side view of the cut-out roller 34 shown in Fig. 5 A.
It is same shape in the projection 30 shown in side view and Fig. 3 B of the roller surface 34A of cut-out roller 34 projection (the second projection) 36 arranged, but the projection of Fig. 3 A 30 is the one thing of column, in contrast, projection shown in Fig. 5 A 36 is by by the small pieces 38,38 of lateral section fan shape ... and the rotating shaft 35 of cut-out roller 34 has the interval of regulation abreast and arranges and constitute.
Cut-out roller 34 shown in Fig. 5 A, Fig. 5 B also has the effect identical with the cut-out roller 16 shown in Fig. 3 A, Fig. 3 B.
It addition, the height of the aspect ratio projection 28 of the projection 36 of cut-out roller 34 is low.That is, the height H1 of the projection 36 axis of rotation 35A from cut-out roller 34 is set to lower than the projection 28 height H2 from axis of rotation 35A.The height H2 of height H1 and projection 28 by so setting projection 36, the edge 28B of the direction of rotation upstream side in the top surface edge of projection 28 can the lower surface of lower section of cutting line 14 (with reference to Fig. 1) of jack-up ribbon glass plate 12, therefore, it is possible to ribbon glass plate 12 is assuredly shut off along cutting line 14.
Fig. 6 A indicates that the axonometric chart of the second variation of cut-out roller 40, and Fig. 6 B is the side view of the cut-out roller 40 shown in Fig. 6 A.
It is conformed with (the second projection) 42 at the roller surface 40A of cut-out roller 40.This projection 42 is at the direction of rotation stream side surface of the projection 28 of cut-out roller 40 and is provided spaced apart near projection 28, arranges abreast with the rotating shaft 41 of cut-out roller 40.And, projection 42 is set by the transporting velocity of ribbon glass plate 12 (with reference to Fig. 1 etc.) and the circumferential speed of cut-out roller 40 relative to the interval of projection 28, is set as that carrying leading section, the direction 12A being prevented from ribbon glass plate 12 is to the roller surface 40A interval fallen.It should be noted that gap can be not provided with between projection 28 and projection 42, and setting that projection 42 is connected with projection 28.
Cut-out roller 40 shown in Fig. 6 A, Fig. 6 B also has the effect identical with the cut-out roller 16 shown in Fig. 3 A, Fig. 3 B.
It addition, the height of the aspect ratio projection 28 of the projection 42 of cut-out roller 40 is low.That is, the height H1 of the projection 42 axis of rotation 41A from cut-out roller 40 is set to lower than the projection 28 height H2 from axis of rotation 41A.The height H2 of height H1 and projection 28 by so setting projection 42, the edge 28B of the direction of rotation upstream side in the top surface edge of projection 28 can the lower surface of lower section of cutting line 14 (with reference to Fig. 1) of jack-up ribbon glass plate 12, therefore, it is possible to ribbon glass plate 12 is assuredly shut off along cutting line 14.

With reference to the action specification figure shown in Figure 14 A to Figure 14 D, the effect of cut-out roller 60 is described.
The lower surface of the lower section of the cutting line 14 of ribbon glass plate 12 is by cutting off with projection 28 jack-up of roller 60, then, as shown in Figure 14 A when ribbon glass plate 12 is cut off along cutting line 14, as Figure 14 B, carrying leading section, the direction 12A and the height H with projection 28 of the ribbon glass plate 12 of carrying direction upstream side2Equal height H1Projection 62 contact.Thus, according to cut-out roller 60, it is prevented from carrying leading section, the direction 12A of ribbon glass plate 12 to the roller surface 60A of cut-out roller 60 situation about falling, and as Figure 14 C, Figure 14 D, when being inhibited the bending of carrying leading section, direction 12A by projection 62 by cut-out roller 60, to the roller 20,20 arranged with the downstream of roller 60 in cut-out ... join swimmingly.
Thus, according to cut-out roller 60, it is possible to prevent the breakage at carrying leading section, the direction 12A that ribbon glass plate 12 has just been cut off the ribbon glass plate 12 occurred afterwards, and ribbon glass plate 12 can be carried swimmingly from cut-out roller 60 downstream side.
It addition, as described above, the height H of projection 62 is made1Height H with projection 282Equal, and the circumferential speed of the projection 62 of cut-out roller 60 is set as the speed identical with the transporting velocity of ribbon glass plate 12, thus need not change the rotating speed of cut-out roller 60, it is possible to prevent the contact damage that the difference of the transporting velocity of ribbon glass plate 12 and the circumferential speed of projection 62 causes from carrying banding glass plate 12.
It should be noted that, the circumferential speed of the projection 62 of cut-out roller 60 is set as the speed identical with the transporting velocity of ribbon glass plate 12 from the position of readiness of Figure 14 D to the position of Figure 14 C, at the position of readiness from the position of Figure 14 C to Figure 14 D, it is set as the speed higher than the transporting velocity of ribbon glass plate 12.
It addition, the rotating shaft by the second projection Yu cut-out roller is arranged abreast, thus the whole region of carrying leading section, the direction 12A of the ribbon glass plate 12 of carrying direction upstream side will not fall to roller surface.
And, as the material of the second projection, it is that rubber, polyurethane, foamed styrene etc. are except the soft component of metal, it is preferable that be installed on the mode of cut-out roller 16 in removable mode, for instance chimeric mode, bonding mode.
Additionally, be not defined to ribbon glass plate 12 as the glass plate cutting off object, as long as carry the rectangular glass cut off by cut-out roller, its shape can be any.
