SUMMERY OF THE UTILITY MODEL
Summary of the utility model
Problem to be solved by utility model
According to the manufacturing apparatus described in patent document 1, the position of the lug folding mechanism can be adjusted in accordance with the meandering or width variation of the glass ribbon continuously formed and fed from the molten glass.
However, since the position detector that detects the position of the edge portion of the glass ribbon is provided in the cross cutting mechanism that is separated from the edge folding mechanism in the conveyance direction of the glass ribbon, it is difficult to accurately adjust the position of the edge folding mechanism. Further, since the position detector detects the variation of the roller that comes into contact with the edge portion of the glass ribbon, the detection result is affected by vibration or the like.
The glass sheet manufacturing apparatus further includes, at both edge portions of the glass ribbon, other mechanisms such as a slitting mechanism that machines a longitudinal tangent line in the longitudinal direction by a cutter, and a lateral folding mechanism that applies a bending force from below to cut the glass ribbon along a lateral tangent line while pressing the vicinity of both edges of the glass ribbon by rollers. However, the manufacturing apparatus of patent document 1 only adjusts the position of the tab folding mechanism, and does not have a function of adjusting the position of the cutter of the slitting mechanism or the roller of the transverse folding mechanism in accordance with the fluctuation of the edge portion of the glass ribbon. Therefore, it is required to perform position adjustment in other mechanisms such as the above-described slitting mechanism and the above-described lateral folding mechanism.
Therefore, an object of the present invention is to provide a glass plate manufacturing apparatus capable of manufacturing a high-quality glass plate by accurately adjusting the position of a mechanism for performing various types of processing on a continuously fed glass ribbon.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the drawings.
Fig. 1 is a schematic plan view illustrating the structure of the glass plate manufacturing apparatus according to the present embodiment.
As shown in fig. 1, the glass plate manufacturing apparatus 100 of the present embodiment includes a conveying mechanism 12, and the conveying mechanism 12 is constituted by a roller conveyor including a plurality of rollers 11. The conveyance mechanism 12 conveys the glass ribbon GR, which is cooled by an annealing furnace (not shown) after being formed in a float bath (not shown) on the upstream side and continuously sent out, to the downstream side in the conveyance direction X.
The glass plate manufacturing apparatus 100 includes a slitting mechanism 13, a transverse cutting mechanism 14, a transverse folding mechanism 15, and a lug folding mechanism 16. The longitudinal cutting mechanism 13, the transverse cutting mechanism 14, the transverse folding mechanism 15, and the lug folding mechanism 16 are provided in this order from the upstream side to the downstream side in the conveyance direction X of the glass ribbon GR in the conveyance mechanism 12.
The longitudinal cutting mechanism 13 processes a longitudinal tangent line L1 in the longitudinal direction at both edge portions of the glass ribbon GR conveyed by the conveying mechanism 12. The longitudinal cutting line L1 is a scribe line for separating the product portion GA and the ear portion GB, and is formed at the boundary between the product portion GA and the ear portion GB. The glass ribbon GR is divided into a product portion GA and an ear portion GB by being processed by the longitudinal cutting line L1. The longitudinal cutting mechanism 13 includes a pair of disk-shaped cutters 21, and presses the cutters 21 near both edges of the glass ribbon GR conveyed in the conveying direction X to form a longitudinal cutting line L1 on the upper surface of the glass ribbon GR.
The cross cutting mechanism 14 processes a cross cut line L2 with respect to the glass ribbon GR conveyed by the conveying mechanism 12. The transverse cutting line L2 is a scribe line for cutting the glass ribbon GR to cut out the glass sheet G1. The transverse cutting mechanism 14 includes a disk-shaped cutter 22, and presses the cutter 22 against the glass ribbon GR while moving the cutter 22 in a direction obliquely intersecting the conveyance direction X, thereby forming a transverse tangent L2 as a scribe line on the upper surface of the glass ribbon GR in the width direction orthogonal to the conveyance direction X.
The glass sheet manufacturing apparatus 100 of this example includes two cross cutting mechanisms 14, and the cross cutting lines L2 can be formed at narrow intervals along the longitudinal direction as the conveyance direction X by the two cross cutting mechanisms 14.
The transverse folding mechanism 15 is a mechanism that applies a bending force from below to the glass ribbon GR conveyed in the conveyance direction X by the conveyance mechanism 12 and cuts the glass ribbon GR along a transverse tangent line L2. Thereby, the glass ribbon GR is cut along the transverse tangent line L2, and becomes a glass sheet G1 divided in the conveying direction X.
The ear folding mechanism 16 cuts the glass sheet G1 cut from the glass ribbon GR by applying a bending force to the glass sheet along the longitudinal cutting line L1 at both edges. Thus, the glass sheet G1 is cut at the longitudinal cut line L1, and becomes a glass sheet G2 after the ear portions GB on both edges are separated from the product portion GA.
Next, the slitting mechanism 13, the transverse cutting mechanism 14, the transverse folding mechanism 15, and the lug folding mechanism 16, which are processing mechanisms provided in the glass sheet manufacturing apparatus 100 having the above-described configuration, will be described in detail.
(slitting mechanism)
Fig. 2 is a schematic front view of the slitting mechanism as viewed from the downstream side in the conveying direction. Fig. 3 is a partial schematic front view of the slitting mechanism as viewed from the upstream side in the conveying direction.
As shown in fig. 2, in the present embodiment, the slitting mechanism 13 has a gate-shaped frame 31. The frame 31 is composed of a pair of support columns 32 erected on both sides of the transport mechanism 12, and a beam 33 bridged over the upper ends of the support columns 32.
The beam 33 is provided with two support portions 34, and the cutter 21 is supported by these support portions 34. The cutter 21 supported by the support portion 34 rolls while being pressed against the surfaces near both edge portions of the glass ribbon GR. Thus, the cutter 21 processes the longitudinal line L1 on the glass ribbon GR.
The support portion 34 supporting the cutter 21 is movable along the beam 33 by the position adjusting portion 30 provided between the beam 33 and the support portion. Thus, the cutter 21 can adjust the contact position with the glass ribbon GR in the width direction thereof by moving the support portion 34 along the beam 33.
As shown in fig. 3, the slitting mechanism 13 has a slitting edge portion detecting sensor 37. The slit edge detection sensor 37 is attached to each support portion 34. The slit edge detection sensor 37 attached to the support portion 34 is provided upstream in the conveyance direction X with respect to the cutter 21 supported by the support portion 34, and optically detects the edge of the glass ribbon GR. The longitudinal edge detection sensor 37 includes three photosensors S1, S2, and S3, and these photosensors S1, S2, and S3 are arranged in this order from the center side in the width direction of the glass ribbon GR, that is, from the inner side. The photosensor S1 and the photosensor S2 are disposed at an interval from each other, and the photosensor S2 and the photosensor S3 are adjacent to each other.
(Cross cutting mechanism)
Fig. 4 is a schematic front view of the cross cutting mechanism as viewed from the downstream side in the conveying direction. Fig. 5 is a partial schematic front view of the cross cutting mechanism as viewed from the downstream side in the conveying direction. Fig. 6 is a schematic configuration diagram showing a position adjustment unit of the cross cutting mechanism. Fig. 7 is a partial schematic front view of the cross cutting mechanism as viewed from the upstream side in the conveying direction.
As shown in fig. 4, in the present embodiment, the traverse mechanism 14 has a gate-shaped frame 41. The frame 41 is composed of a pair of support columns 42 erected on both sides of the transport mechanism 12, and a beam 43 extending over the upper ends of the support columns 42. The frame 41 is disposed such that a beam 43 obliquely crosses above the conveyance mechanism 12.
A table 44 is provided on the beam 43, and the table 44 is movable along a rail 45 provided on the beam 43. A cylinder 46 is mounted on the table 44. The cylinder 46 has a rod 47 projecting downward, and advances and retracts the rod 47. A cutter holder 48 is provided at the lower end of the rod 47, and the cutter 22 is rotatably supported by the cutter holder 48. The cutter 22 is moved from the cutting start position on one end side of the beam 43 to the cutting end position on the other end side of the beam 43 by the movement of the table 44. At this time, the cutter 22 rolls while being pressed against the surface of the glass ribbon GR by the cylinder 46. Thus, the cutter 22 forms a transverse cutting line L2 in the glass ribbon GR.
As shown in fig. 5, in the present embodiment, the transverse cutting mechanism 14 includes an auxiliary plate 49. The auxiliary plate 49 is a wedge-shaped plate, and has a slide path 49a with an upper surface inclined downward toward the front end. The rear end of the auxiliary plate 49 is fixed to the frame 50. The base end of the frame 50 is supported by the beam 43, and a position adjusting portion 51 is provided between the frame 50 and the beam 43.
As shown in fig. 6, the position adjustment unit 51 includes: a drive motor 52 having a drive shaft 52a, a transmission part 53, and a shaft 54. In the position adjusting portion 51, when the driving shaft 52a of the driving motor 52 rotates, the rotational force is transmitted to the shaft 54 via the transmitting portion 53, and the shaft 54 is rotated. The position of the auxiliary plate 49 is adjusted by rotating the shaft 54 and moving the frame 50 along the beam 43. The position adjustment unit 51 can bring the drive motor 52 into contact with and separate from the transmission unit 53. In the position adjusting portion 51, the position of the auxiliary plate 49 can be adjusted by manually rotating the shaft 54 by rotating the handle 53a of the transmission portion 53 in a state where the drive motor 52 is separated from the transmission portion 53.
As shown in fig. 7, the cross cutting mechanism 14 has a cross edge detection sensor 57. In the present embodiment, the transverse edge detection sensor 57 is attached to the auxiliary plate 49. The transverse edge detection sensor 57 attached to the auxiliary plate 49 is provided upstream of the cutter 22 in the conveyance direction X, and optically detects the edge of the glass ribbon GR. The transverse edge detection sensor 57 includes three photosensors S1, S2, and S3, and these photosensors S1, S2, and S3 are arranged in this order from the center side in the width direction of the glass ribbon GR, that is, from the inner side. The photosensor S1 and the photosensor S2 are disposed at an interval from each other, and the photosensor S2 and the photosensor S3 are adjacent to each other.
(Cross-folding mechanism)
Fig. 8 is a schematic front view of the transverse folding mechanism as viewed from the downstream side in the conveying direction. Fig. 9 is a schematic side view of the lateral folding mechanism. Fig. 10 is a partial schematic front view of the transverse folding mechanism as viewed from the upstream side in the conveying direction.
As shown in fig. 8 and 9, in the present embodiment, the lateral folding mechanism 15 includes a jack roller 60. The lift-up roller 60 is provided on the lower side of the glass ribbon GR and is disposed along the width direction of the glass ribbon GR. The lift roller 60 is lifted and lowered by a lifting mechanism (not shown).
The lateral folding mechanism 15 has a gate-shaped frame 61. The frame 61 is composed of a pair of support columns 62 erected on both sides of the transport mechanism 12, and a beam 63 extending over the upper ends of the support columns 62. The beam 63 is provided with two support portions 64, and the rollers 65 are rotatably supported by these support portions 64. The rollers 65 are provided in pairs on the upstream side and the downstream side in the conveyance direction X with the jacking rollers 60 interposed therebetween, and abut against the upper surfaces of the lug portions GB of the glass ribbon GR.
In the lateral folding mechanism 15, when the lateral tangent line L2 of the glass ribbon GR enters between the rollers 65 upstream and downstream in the conveyance direction X, the lift-up roller 60 rises. Thus, the glass ribbon GR is pushed up in the width direction by the jacking rollers 60 in a state where the upper surface is pressed by the rollers 65 on the upstream side and the downstream side in the conveying direction X across the jacking rollers 60. Thereby, the glass ribbon GR is cut along the transverse tangent line L2 by the bending force acting in the width direction.
The support portion 64 that supports the roller 65 is movable along the beam 63 by a position adjustment portion 69 provided between the support portion and the beam 63. Thus, the roller 65 can be adjusted in the contact position with the glass ribbon GR in the width direction thereof by the support portion 64 moving along the beam 63.
As shown in fig. 10, the lateral folding mechanism 15 has a lateral folding edge detection sensor 67. In the present embodiment, the lateral folded edge detection sensor 67 is attached to each support portion 64. The lateral folding edge detection sensor 67 attached to the support portion 64 is provided upstream in the conveyance direction X with respect to the rollers 65 supported by the support portion 64, and optically detects the edge of the glass ribbon GR. The lateral folding edge detection sensor 67 includes three photosensors S1, S2, and S3, and these photosensors S1, S2, and S3 are arranged in this order from the center side, i.e., the inner side, in the width direction of the glass ribbon GR. The photosensor S1 and the photosensor S2 are disposed at an interval from each other, and the photosensor S2 and the photosensor S3 are adjacent to each other.
(ear folding mechanism)
Fig. 11 is a schematic front view of the ear folding mechanism as viewed from the downstream side in the conveying direction. Fig. 12 is a schematic front view of one of the ear folding portions of the ear folding mechanism as viewed from the downstream side in the conveying direction. Fig. 13 is a schematic front view of one of the lug portions of the lug folding mechanism as viewed from the upstream side in the conveying direction.
As shown in fig. 11, in the present embodiment, the ear folding mechanism 16 has a gate-shaped frame 81. The frame 81 is composed of a pair of support columns 82 erected on both sides of the transport mechanism 12, and a beam 83 spanning the upper ends of the support columns 82.
Two folded ear portions 71 are provided at the beam 83. The ear piece 71 includes a support portion 72 and a swing frame 73, and the swing frame 73 is swingably supported by the support portion 72. The beam 83 is provided with a guide rail 84, and the support portion 72 is movably supported by the guide rail 84 in the tab portion 71. The beam 83 is provided with a position adjustment portion 80. The position adjusting portion 80 is composed of a drive motor that rotates a ball screw, not shown, and the support portion 72 screwed with the ball screw moves along the guide rail 84 by rotating the ball screw by the position adjusting portion 80. Thus, the lug portion 71 moves in the direction orthogonal to the conveyance direction X of the glass ribbon GR, and moves in the width direction of the glass sheet G1 separated from the glass ribbon GR.
The swing frame 73 has a lower arm 75 and an upper arm 76. The lower arm 75 and the upper arm 76 extend in parallel with each other with a space therebetween. A plurality of support rollers 77 aligned in the conveying direction X are provided above the lower arm 75. The upper arm 76 has a plurality of pressing projections 78 arranged in the conveying direction X on the lower side thereof.
In this lug folding mechanism 16, the lug portions GB on both edges of the glass ribbon GR pass between the lower arm 75 and the upper arm 76 of each lug portion 71. Then, the glass ribbon GR is conveyed with the lower portions of the lug portions GB thereof supported by the support rollers 77 provided on the lower arm 75 of the swing frame 73.
In this state, as shown in fig. 12, when the swing frame 73 swings downward, the support rollers 77 of the lower arm 75 of the swing frame 73 move downward, and the upper surfaces of the lug portions GB of the glass ribbon GR are pressed down by the pressing projections 78 provided on the upper arm 76. Thereby, a bending force acts on the glass ribbon GR along the longitudinal tangent line L1 at both edges, and the glass ribbon GR is cut along the longitudinal tangent line L1. Thus, the glass ribbon GR is divided by the transverse folding mechanism 15 into glass plates G1, and glass plates G2 are formed by the ear folding mechanism 16 after the ear portions GB on both edges are separated from the product portion GA.
As shown in fig. 13, the ear folding mechanism 16 has an ear folding edge portion detection sensor 87. In the present embodiment, the tab edge detection sensor 87 is supported by the support portion 72 of each tab portion 71 via a stay 85. These tab edge detection sensors 87 supported by the stay 85 are provided on the upstream side in the conveyance direction X with respect to the swing frame 73, and optically detect the edge of the glass ribbon GR. The tab edge portion detection sensor 87 includes three photosensors S1, S2, and S3, and these photosensors S1, S2, and S3 are arranged in this order from the center side in the width direction of the glass ribbon GR, that is, from the inner side. The photosensor S1 and the photosensor S2 are disposed at an interval from each other, and the photosensor S2 and the photosensor S3 are adjacent to each other.
Fig. 14 is a schematic block diagram illustrating a control system of the manufacturing apparatus.
As shown in fig. 14, the glass plate manufacturing apparatus 100 includes a control unit 200. The control unit 200 is connected to the conveying mechanism 12, the slitting mechanism 13, the cross cutting mechanism 14, the cross folding mechanism 15, and the ear folding mechanism 16, and controls these mechanisms. The slit edge detection sensor 37, the transverse edge detection sensor 57, the transverse folded edge detection sensor 67, and the tab edge detection sensor 87 are connected to the control unit 200, and detection signals from the edge detection sensors 37, 57, 67, and 87 are transmitted to the control unit 200. The control unit 200 performs position adjustment control of the slitting mechanism 13, the transverse cutting mechanism 14, the transverse folding mechanism 15, and the ear folding mechanism 16, and the like, based on detection signals from the edge detection sensors 37, 57, 67, and 87.
Next, control of each mechanism and the like by the control unit 200 will be described.
Among the three photosensors S1, S2, and S3 of the edge detection sensors 37, 57, 67, and 87, the photosensor S1 is a sensor for abnormality detection, the photosensor S2 is a sensor for detecting a rolling motion in the width reducing direction, and the photosensor S3 is a sensor for detecting a rolling motion in the width expanding direction. The controller 200 performs position adjustment of the respective mechanisms and the like as follows based on the on/off states (1) to (4) of the three photosensors S1, S2, S3 of the edge detection sensors 37, 57, 67, 87.
(slitting mechanism)
(1) S1: turn on S2: turn on S3: disconnect
When the photosensors S1 and S2 of the longitudinal edge detection sensor 37 are turned on and the photosensor S3 is turned off, the control unit 200 determines that the glass ribbon GR is conveyed in a steady state and determines that the edge of the glass ribbon GR is at a fixed position. In this case, the control unit 200 does not perform the position adjustment of the slitting mechanism 13 and maintains the position of the cutter 21.
(2) S1: turn on S2: turn on S3: is connected to
When all of the photosensors S1, S2, and S3 of the slit edge detection sensor 37 are turned on, the controller 200 determines that the edge portion of the glass ribbon GR is displaced (widened) outward. In this case, the control unit 200 transmits a control signal to the slitting mechanism 13 and drives the position adjusting unit 30. Thus, the support portion 34 supporting the cutter 21 is moved outward in the width direction until the photosensor S3 is turned off, and the position of the longitudinal tangent L1 to the glass ribbon GR by the cutter 21 is appropriately set.
(3) S1: turn on S2: disconnect S3: disconnect
When the photosensor S1 of the slit edge detection sensor 37 is on and the photosensors S2 and S3 are off, the controller 200 determines that the edge of the glass ribbon GR is displaced inward (narrowed). In this case, the control unit 200 transmits a control signal to the slitting mechanism 13 and drives the position adjusting unit 30. Thus, the support portion 34 supporting the cutter 21 is moved inward in the width direction until the optical sensor S2 is turned on, and the position of the longitudinal tangent L1 to the glass ribbon GR by the cutter 21 is appropriately set.
(4) S1: disconnect S2: disconnect S3: disconnect
When all of the photosensors S1, S2, and S3 of the longitudinal edge detection sensor 37 are off, the control unit 200 determines that the conveyance is abnormal, and the glass ribbon GR is not conveyed due to, for example, a breakage or the like. In this case, the control unit 200 does not control the slitting mechanism 13, and sends a signal to an alarm device (not shown) to issue an alarm in order to notify an abnormality.
(Cross cutting mechanism)
(1) S1: turn on S2: turn on S3: disconnect
When the photosensors S1 and S2 of the cross edge detection sensor 57 are turned on and the photosensor S3 is turned off, the control unit 200 determines that the glass ribbon GR is conveyed in a steady state, and further determines that the edge of the glass ribbon GR is at a fixed position. In this case, the control unit 200 does not perform the position adjustment of the cross cutting mechanism 14, and maintains the position of the auxiliary plate 49.
(2) S1: turn on S2: turn on S3: is connected to
When all the photosensors S1, S2 of the cross edge detection sensor 57 are on, the controller 200 determines that the edge of the glass ribbon GR is displaced (widened) outward. In this case, the control unit 200 transmits a control signal to the cross cutting mechanism 14 and drives the position adjustment unit 51. Thus, the auxiliary plate 49 is moved outward in the width direction until the optical sensor S3 turns off, and the cutting start position of the cutter 22 with respect to the glass ribbon GR is made to correspond to an appropriate position.
(3) S1: turn on S2: disconnect S3: disconnect
When the optical sensor S1 of the transverse edge detection sensor 57 is on and the optical sensors S2 and S3 are off, the control unit 200 determines that the edge of the glass ribbon GR is displaced inward (pinched). In this case, the control unit 200 transmits a control signal to the cross cutting mechanism 14 and drives the position adjustment unit 51. Thus, the auxiliary plate 49 is moved inward in the width direction until the optical sensor S2 is turned on, and the cutting start position of the cutter 22 with respect to the glass ribbon GR is made to correspond to an appropriate position.
(4) S1: disconnect S2: disconnect S3: disconnect
When all of the photosensors S1, S2, and S3 of the cross edge detection sensor 57 are off, the control unit 200 determines that the glass ribbon GR is not conveyed due to a conveyance failure, for example, a breakage or the like. In this case, the control unit 200 does not control the traverse mechanism 14, and sends a signal to an alarm device (not shown) to issue an alarm in order to notify an abnormality.
(Cross-folding mechanism)
(1) S1: turn on S2: turn on S3: disconnect
When the photosensors S1 and S2 of the transverse folding edge detection sensor 67 are turned on and the photosensor S3 is turned off, the control unit 200 determines that the glass ribbon GR is conveyed in a steady state, and further determines that the edge of the glass ribbon GR is at a fixed position. In this case, the control unit 200 does not perform the position adjustment of the lateral folding mechanism 15, and maintains the position of the roller 65.
(2) S1: turn on S2: turn on S3: is connected to
When all the photosensors S1, S2 of the lateral folding edge detection sensor 67 are turned on, the controller 200 determines that the edge of the glass ribbon GR is displaced (widened) outward. In this case, the control unit 200 transmits a control signal to the lateral folding mechanism 15 and drives the position adjustment unit 69. Thus, the support portion 64 supporting the rollers 65 is moved outward in the width direction until the optical sensor S3 is turned off, and the pressing positions of the rollers 65 against the lug portions GB of the glass ribbon GR are made to correspond to appropriate positions.
