[Prior art]
As is well known, glass substrates used in the field of manufacturing flat displays such as TFT-LCD (Thin Film Transistor Driven Color Liquid Crystal Display), PDP (Plasma Display Panel), EL (Electroluminescence) and the like are glass melting furnaces. After the water glass melted in step 1 is supplied to a melt molding machine to produce a glass substrate, the glass substrate is cut so as to meet the primary standard, and a protective film is coated on the surface of the glass substrate and conveyed to the glass substrate processing line. In the glass substrate processing line, after the film is peeled off from the glass substrate, the glass substrate is re-cut into a size that meets the standard of the flat display. In the subsequent coating process, for example, silica (SiO ₂ ) An ITO (Indium tin oxide) film is coated as the film and the conductive film.
[0003]
In a general glass substrate film removing apparatus, a glass substrate film to be transferred is adhered and peeled to the surface of an adhesive urethane roller while the glass substrate is transferred using a roller conveyor.
[0004]
On the other hand, in Patent Document 1, the pressure-sensitive adhesive tape is supplied so as to be wound along the outer surface of the presser roll, and the presser roll is moved after the film is adhered to the pressure-sensitive adhesive tape while pressing the film of the glass substrate with the presser roll. A technique for removing a film from a glass substrate with a paper pipe interlocked with a presser roll is disclosed.

[Problems to be solved by the invention]
By the way, if foreign matter such as dust adheres to the surface of the urethane roller described above, the adhesiveness of the urethane roller is reduced and the function is lost. Therefore, the operation of the film removing device is periodically stopped, and the surface of the urethane roller is removed. Since it must be periodically cleaned, there is a problem that productivity is greatly reduced. In particular, in order to regenerate the adhesiveness of the urethane roller, it is necessary to clean it using a solvent such as methyl ethyl ketone that is harmful to the human body. The waste film peeled off from the glass substrate by the urethane roller takes time and labor for the operator to separately collect and dispose of it, and much time and effort is put into reducing the waste film volume and disposing it. There is a problem that the production cost increases. Generally, in order to efficiently remove the waste film, the worker performs the removal work about once an hour. If the worker does not remove the waste film and leaves it in the processing line, There is a problem that the waste film is scattered around the line and not only hinders the work environment but also flows into the processing line apparatus and may cause a failure.

It is an object of the present invention to provide a film removing apparatus and a film removing method that can efficiently perform a series of processes such as the above, improve productivity, and greatly reduce production costs.
[0009]
Another object of the present invention is to provide a film removal apparatus and a film removal method that can immediately collect waste films that are peeled off and discharged from a plate-like member to improve the working environment.
[0010]
Still another object of the present invention is to provide a film removing apparatus and a film removing method that can easily reduce the volume of waste film and reduce the cost of disposal.
[0011]
[Means for Solving the Problems]

[0035]
Hereinafter, a method for removing a film by the glass substrate film removing apparatus according to the present invention having such a configuration will be described with reference to FIGS.
[0036]
Referring to FIGS. 1, 4, and 9, first, the blower 36 of the first air suction device 35, the motor 55 of the rotary gate 54, and the first turbo blower 61 of the second air suction device 60 are controlled by the controller 80. And the blower 64 of the 3rd air suction apparatus 63 is operated, and the preparation which collects the waste film 2a peeled and discharged | emitted from the glass substrate 1 is made (S100).
[0037]
As shown in FIGS. 3 and 7A, the cylinder rod 24a is advanced by the operation of the first air cylinder 24, and the air blaster 20 is lowered from the standby position P2 to the removal position P1 of the roller conveyor 10 to prepare. (S101). As the air blaster 20 descends, the pinch roller 28 is separated from the sub roller 37 of the vacuum suction rolling device 30 with an interval through which the glass substrate 1 can pass.
[0038]
Referring to FIGS. 1 and 4, when the glass substrate 1 is supplied to the transfer roller 12 of the roller conveyor 10 so that the film 2 faces downward, when the roller conveyor 10 is operated, the glass substrate is rotated by the transfer roller 12. It is transferred to the removal position P1 along the transfer direction 13 by the movement (S102).
[0039]
The glass substrate 1 transferred by the operation of the roller conveyor 10 is detected by the sensor 14, and the sensor 14 inputs a detection signal of the glass substrate 1 to the controller 80, and the controller 80 detects the glass substrate by the detection signal input from the sensor 14. It is determined whether or not the leading end in the transfer direction has reached the removal position P1 (S103).
[0040]
If the controller 80 determines that the front end of the glass substrate 1 in the transfer direction has reached the removal position P1 (YES), the controller 80 stops the operation of the roller conveyor 10 (S104). In this embodiment, the roller conveyor 10 is stopped when the tip of the glass substrate 1 in the transfer direction passes between the pinch roller 28 and the sub roller 37 of the vacuum suction rolling device 30 as shown in FIG. Is set.
[0041]
3 and 7A, when the operation of the roller conveyor 10 is stopped, the controller 80 advances the cylinder rod 27a by the operation of the second air cylinder 27, and the air nozzle of the air blaster 20 23 is brought close to the front end of the glass substrate 1 in the transfer direction (indicated by a one-dot chain line in FIG. 7A), compressed air is jetted through the air nozzle 23 of the air blaster 20, and the film 2 is peeled off from the glass substrate 1 (S105). . When compressed air is ejected to the tip of the glass substrate 1 in the transport direction using the air nozzle 23 of the air blaster 20, the phenomenon that the tip of the glass substrate 1 in the transport direction floats from the sub roller 37 of the vacuum suction rolling device 30 due to the jet force of the compressed air. Although it may occur, as shown in FIG. 7A, the pinch roller 28 positioned above the sub-roller 37 supports the upper surface of the glass substrate 1, so that the phenomenon of the glass substrate 1 floating is prevented. .
[0042]
Next, as shown in FIG. 7B, after the film 2 is peeled off, the cylinder rod 27a is moved backward by the operation of the second air cylinder 27 so that the glass substrate 1 to be transferred does not interfere with the air blaster 20. Then, the air nozzle 23 of the air blaster 20 is separated from the front end of the glass substrate 1 in the transfer direction, the cylinder rod 24a is moved backward by the operation of the first air cylinder 24, and the air blaster 20 is moved from the removal position P1 to the standby position P2. Return (S106).
[0043]
When the air blaster 20 returns to the standby position P2, the glass substrate 1 is transferred again by the operation of the roller conveyor 10, and discharged from the removal position P1 (S107).
[0044]
Referring to FIGS. 3, 4, 8 </ b> A, and 8 </ b> B, waste discharged from the glass substrate 1 by the operation of the air blaster 20 while the glass substrate 1 is discharged by the operation of the roller conveyor 10. The film 2a is attracted to the surface of the sub-roller 37 by the suction input transmitted by the suction hole 37a of the sub roller 37, the suction hole 31a of the main roller 31, and the suction hole 33a of the suction pipe 33. The main roller 31 of the vacuum suction rolling device 30 to which the driving force of the motor 41 is transmitted by the power transmission belt 42 is rotated in the transfer direction of the glass substrate 1, and is attracted to the surface of the sub roller 37 by the rotation of the main roller 31. The waste film 2a is detached from the glass substrate 1 and discharged from the removal position P1 of the roller conveyor 10 (S108). 8B, when the suction hole 37a of the sub-roller 37 to which the waste film 2a is sucked away from the suction hole 33a of the suction pipe 33 due to the rotation of the main roller 31, the suction of the corresponding sub-roller 37 is performed. The suction force acting on the hole 37 a is weakened, and the waste film 2 a adsorbed on the surface of the sub roller 37 is smoothly peeled off from the sub roller 37. By operating the roller conveyor 10 in this way, the glass substrate 1 coated with the film 2 is continuously transferred, and the air blaster 20 is operated to inject compressed air at the front end of the glass substrate 1 in the transfer direction. After peeling the film 2 coated on the glass substrate 1, the waste film 2 a peeled off from the glass substrate 1 is quickly discharged from the glass substrate 1 by the operation of the vacuum suction rolling device 30, thereby greatly improving productivity. The production cost can be reduced by automating the removal of the film 2. And the working environment can be improved by the rapid automatic discharge of the waste film 2a by the vacuum suction method of the vacuum suction rolling device 30, and the failure of the processing line that causes the waste film 2a to remain in the glass substrate processing line is effective. Can be prevented.
[0045]
As shown in FIGS. 9 and 10, the waste film 2 a peeled off and discharged by the sub roller 37 is received by the suction hood 51 of the collection device 50. At this time, the suction force generated by the operation of the first turbo blower 61 is applied to the inlet 51a of the suction hood 51 to the cyclone 53 via the first film transfer line 52. Therefore, the vacuum suction rolling device 30 The waste film 2 a peeled off from the sub-roller 37 is immediately received at the inlet 51 a of the suction hood 51. The waste film 2a is sucked and collected inside the cyclone 53 through the outlet 51b of the suction hood 51, the first film transfer line 52, and the inlet 53a of the cyclone 53 (S109). The secondary suction force generated by the operation of the blower 64 controls the internal pressure acting on the inlet 53a and the outlet 53b of the cyclone 53 so that the waste film 2a sucked at the inlet 53a of the cyclone 53 can be discharged at the outlet 53b. . That is, the internal pressure generated at the outlet 53b is smaller than the internal pressure generated at the inlet 53a side of the cyclone 53 by the blower 64. Accordingly, a low internal pressure is generated on the outlet 53a side with respect to the inlet 53a side of the cyclone 53, so that the waste film 2a sucked at the inlet 53a of the cyclone 53 can be smoothly moved to the outlet 53b and discharged.
[0046]
Subsequently, the waste film 2a moved to the outlet 53b of the cyclone 53 is rotated by the wings 56a and 57a of the first and second rotors 56 and 57 rotated by the driving force of the motor 55 being transmitted by the power transmission belt 58. As a result, the waste film 2a discharged from the outlet 53b of the cyclone 53 and discharged from the outlet 53b of the cyclone 53 is supplied to the automatic compressor 70 through the second film transfer line 71 (S110).
[0047]
The automatic compressor 70 compresses the waste film 2a into a lump (S111).
[0048]
The compressed waste film lump 2b is bound by a binding means, for example, a wire, and discharged (S112). At this time, the automatic compressor 70 automatically compresses and reduces the volume when the supplied waste film 2a reaches a predetermined amount, and the waste film lump 2b bound by the operation of the automatic compressor 70. Weight is about 40-60kg, volume (cm ³ ) Is about 500 × 400 × 600 to 1200. Therefore, the operator can easily discard the waste film lump 2b discharged from the automatic compressor 70.
[0049]
In this embodiment, the glass substrate has been described. However, other materials, for example, a substrate made of a plastic material, can be similarly applied.
[0050]
While preferred embodiments of the invention have been described above, it will be appreciated by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. .
