As shown in FIG. 4, the film removing method of the glass substrate according to the present invention includes the step of transferring the glass substrate 1 for the film 2 removal process (S20), and the feeding direction of the glass substrate 1. Step (S30) of peeling off a portion of the film (2) in advance, and step (50) of peeling off the remainder of the film (2) partly peeled off from the transport direction end of the glass substrate (1).

Prior to the step S20 of transferring the glass substrate 1, a preliminary step S10 is performed.

The preliminary preparation step (S10) is a step (S30) for peeling off part of the film (2) from the feed direction end of the glass substrate 1 in advance, and the film 2 partially peeled off from the feed direction end of the glass substrate (1). In order to perform the step (S50) of peeling off the rest of the pre-peeling brush (Pre-peeling brush) (220) is loaded on the transport path of the glass substrate (1) (S11), the air blaster 410 film 2 ) To the removal position (P1) (S12).

After completing the preliminary preparation step (S10), the step (S20) of transferring the glass substrate 1 is performed.

In the step (S20) of transferring the glass substrate 1, the glass substrate 1 passes through the removal position P1 of the film 2 using the conveyor belt 120 or the roller conveyor 10 (shown in FIG. 1). Glass substrate 1 as shown in FIG. 9 before the glass substrate 1 enters the removal position P1 of the film 2 by the conveyor belt 120 or the roller conveyor 10 (shown in FIG. 1). Step (S30) of peeling a part of the film 2 in advance from the feed direction end of the glass substrate 1 with the prefilling brush 220 loaded on the feed path of (1) is performed.

The step S30 of peeling off a portion of the film 2 from the front end of the transport direction of the glass substrate 1 may include the conveyor belt 120 or the prefilling brush 220 loaded on the transport path of the glass substrate 1.

In the step S30 of peeling off a portion of the film 2 from the front end of the glass substrate 1 in advance, the prefilling brush 220 contacts the front end of the glass substrate 1 so that the friction increases. It is preferable to rotate in the direction opposite to the conveying direction of (1) (S31). Accordingly, the prefilling brush 220 rotates in a direction in which the portion of the prefilling brush 220 that contacts the glass substrate 1 resists the transfer of the glass substrate 1, thereby from the forward direction of the glass substrate 1. Allow the film (2) to peel off well.

When a part of the film 2 is peeled off from the feed direction front end of the glass substrate 1 (S31), the prefilling brush 220 is unloaded to a standby position (S32).

The prefilling brush 220 which peels a part of the film 2 from the transport direction end of the glass substrate 1 is moved from the transport path of the glass substrate 1 to the standby position by the compression of the loading / unloading cylinder 320. It is unloaded.

When the prefilling brush 220 is unloaded to the standby position, the glass substrate 1 having a part of the film 2 peeled off enters the removal position P1 of the film 2 by the conveyor belt 120. Compressed air supplied from the compressed air supply unit (not shown) to the air blaster 410 loaded to the removal position P1 of the film 2 by the operation of the first and second cylinders 422, 423 of the operating unit 420. Is sprayed toward the feed direction front end of the glass substrate 1 which enters the removal position P1 of the film 2 through the air nozzle 412.

As shown in FIG. 10A, the glass substrate 1 is separated from the film 2 in the direction of conveyance by compressed air injected from the air nozzle 412 of the air blaster 410.

When the film 2 is separated from the feed direction front end of the glass substrate 1 by the air blaster 410, the air blaster 410 stands by by operating the first and second cylinders 422 and 423 of the operating part 420. The waste film 2a, which is unloaded into the position and separated from the glass substrate 1, is vacuum-adsorbed by the vacuum adsorption rolling unit 430 and discharged from the removal position P1 of the film 2.

As shown in FIG. 10B, the waste film 2a separated from the feed direction end of the glass substrate 1 by the air blaster 410 is blower 36 (shown in FIG. 1) or a vacuum pump (not shown). A suction hole 431a of the main roller 431 and a suction hole of the sub-roller 433 corresponding to the suction hole 434a formed in the lower portion of the suction pipe 434 by an air suction part (not shown). It adsorb | sucks to the surface of the subroller 433 by the suction force of the air sucked through 433a.

The waste film 2a adsorbed on the surface of the sub-roller 433 is suction fixed by the main roller 431 receiving the driving force of a motor (not shown) by a belt (not shown) from the suction pipe 434. The film is separated from the surface except the lower part of the sub roller 433 to which the suction force of air is not supplied from the suction hole 434a of the pipe 434 or from the vacuum suction rolling unit 430 by the film remover 436. It is discharged from the removal position P1 of 2).

The waste film 2a separated from the vacuum suction rolling unit 430 is guided to the inclined portion of the film remover 436 by the compressed air injected from the injection nozzle 438 and discharged to a predetermined position in the upward direction.

Thus, before removing the film 2 from the glass substrate 1, the prefilling brush 220 is brought into contact with the feed direction end of the glass substrate 1, and the film 2 is removed from the feed direction end of the glass substrate 1. Stripping off a portion of the film not only makes it quick and easy to remove the remainder of the film 2 but also makes it possible to completely remove the film 2 from the glass substrate 1.

The film 2 partially peeled off from the feed direction end of the glass substrate 1 by the prefilling brush 220 is separated from the glass substrate 1 by the injection of compressed air, and the vacuum adsorption rolling unit 430 is separated. By adsorbing and evacuating by vacuum, the film 2 is completely removed from the glass substrate 1 without being removed, and the film 2 can be continuously removed to improve productivity.

According to a preferred embodiment of the present invention as described above, in the process of removing the film from the glass substrate, the film is peeled off from the glass substrate easily and completely by peeling the film from the tip of the glass substrate in the transport direction in advance. To prevent the occurrence of defects, the film removal process of the glass substrate is made to be efficient to improve the productivity.

As described above, the film removing apparatus of the glass substrate according to the present invention allows the film to be peeled off easily and completely from the glass substrate by peeling off the film from the tip of the glass substrate in the feeding direction in the process of removing the film from the glass substrate. It is possible to prevent the occurrence of defects due to the non-removal of the film, and to increase the productivity by making the film removal process of the glass substrate more efficient.

What has been described above is just one embodiment for carrying out the film removing apparatus of the glass substrate according to the present invention, the present invention is not limited to the above-described embodiment, as claimed in the following claims Without departing from the gist of the present invention, those skilled in the art to which the present invention pertains to the technical spirit of the present invention to the extent that various modifications can be made.
