In addition, if this operation is performed simultaneously with the operation for forming the above-described post-cut line 94, the work time can be reduced as the entire operation.

  Thereafter, the cutting platen 40 blows out air from the air holes 41 formed on the upper surface. At the same time, the cutting unit 20 raises the cutting holding portion 24 and lifts the plate glass 90. The lifting height of the plate glass 90 is not particularly limited, but in the present embodiment, the height of lifting the plate glass 90 is about 1 mm. Since the air is blown out from the air holes 41 of the cutting platen 40, the plate glass 90 is supported by the air, and even if the lifting height of the plate glass 90 is only about 1 mm, the plate glass 90 is applied to the cutting platen 40. There will be no damage from touching.

  Thereafter, the cutting unit 20 moves in the downstream direction from the cutting platen 40 to the first dividing table 71 while holding the plate glass 90. At this time, the 1st parting stand 71 blows off air from the blowing hole 75 formed in the upper surface. As in the case of the cutting platen 40, the plate glass 90 is supported by the air blown from the blowout holes 75 of the first dividing table 71, so that the plate glass 90 does not come into contact with the first dividing table 71 and is not damaged. .

  Thereafter, when the cutting unit 20 reaches a predetermined vertical position, the cutting holding unit 24 is lowered, the plate glass 90 is placed on the first dividing table 71, and the holding of the plate glass 90 is released. FIG. 4 shows the position of the cutting unit 20 at this time. Here, the predetermined vertical position means that the front cutting line 93 of the plate glass 90 to be held coincides with the front edge of the first dividing base 71 (the front cutting receiver 85), and from the front cutting line 93. Also, the outer portion 97 (hereinafter, this portion is referred to as a “front ear portion”) is a vertical position where the first dividing groove 79 is located. At the same time when the plate glass 90 is placed on the first dividing table 71, the first dividing table 71 stops air blowing from the blowing holes 75, and the first lower surface suction pad device 77 is moved by the lower surface suction pad 76. The lower surface is adsorbed to fix the plate glass 90 on the first dividing table 71.

  Thereafter, the cutting unit 20 returns to the original height position even when the cutting holding unit 24 is raised, and returns to the above-described cutting unit standby position (see FIG. 2). This is the end of the post-cut conveyance work. Thus, since the cutting unit 20 conveys the glass sheet 90 with the operation of returning to the cutting unit standby position after the cutting operation, the useless movement of the cutting unit 20 is reduced and the cutting operation is performed after the cutting operation. The work up to the transfer work can be performed efficiently. Furthermore, as described above, according to the present embodiment, since the lifting height of the plate glass 90 is small, the time for lifting the plate glass 90 can be shortened, and the carrying work can be performed more efficiently.

[Pre-splitting work]
The pre-splitting operation is mainly performed by the splitting unit 50. As described above, the plate glass 90 is conveyed to the first dividing table 71 by the conveying operation after the cutting, and at this time, the dividing unit 50 stands by at the dividing unit standby position downstream of the first dividing table 71. This state is illustrated in FIG. 4 described above.

  Thereafter, the dividing unit 50 moves to a predetermined vertical position in the upstream direction. The predetermined vertical position here is a vertical position in which the front dividing bar 52 is positioned vertically above the first dividing groove 79, that is, vertically above the front ear portion 97 of the plate glass 90. Subsequently, the dividing unit 50 lowers the front dividing bar 52 and presses the front ear portion 97 from above to apply force. Thereby, the front ear part 97 of the plate glass 90 is parted. After the front ear portion 97 is divided, the front dividing bar 52 is returned to the original height position even if it is raised again. Note that the divided front ear portion 97 falls into the first dividing groove 79 and is dropped and collected in a collection box or chute (not shown) provided therebelow. This completes the pre-splitting operation.

[Conveying work during cutting]
The conveyance work during the division is mainly performed by the division unit 50. After the pre-cutting operation, the cutting unit 50 moves to a predetermined vertical position in the upstream direction. FIG. 5 shows the position of the dividing unit 50 at this time. The predetermined position here means that the rear dividing bar 53 is positioned vertically above a portion 98 (hereinafter, this portion is referred to as a “rear ear portion”) outside the rear cut line 94 of the plate glass 90. The vertical position. The reason why the dividing unit 50 moves to such a vertical position is to smoothly perform the rear left and right dividing operation described later. Then, the cutting unit 50 holds the plate glass 90 by lowering the cutting holding unit 56 and sucking the suction pad 65 of the cutting holding unit 56 onto the upper surface of the plate glass 90.

  Thereafter, the dividing unit 50 raises the dividing holding portion 56 and lifts the plate glass 90. At this time, the first lower surface suction pad device 77 stops the suction of the lower surface suction pad 76, and the first dividing base 71 blows out air from the blowing hole 75 on the upper surface. Here, the lifting height of the plate glass 90 is about 1 mm as in the case of the post-cut conveyance work. However, since the air is blown out from the blowing hole 75 of the first dividing table 71, the plate glass 90 is divided into the first dividing portion. There is no case where the table 71 is touched and damaged.

  Thereafter, the dividing unit 50 moves in the downstream direction from the first dividing table 71 via the intermediate dividing table 72 to the second dividing table 73 while holding the plate glass 90. At this time, the 2nd parting stand 73 blows off air from the blowing hole 82 formed in the upper surface. Similarly to the case of the blowout hole 75 of the first dividing table 71, the air blown out from the blowing hole 82 does not cause the plate glass 90 to come into contact with the second dividing table 73 and be damaged.

  Thereafter, when the cutting unit 50 reaches a predetermined vertical position, the cutting holding unit 56 is lowered to place the plate glass 90 on the second cutting table 73 and release the holding of the plate glass 90. FIG. 6 shows the position of the dividing unit 50 at this time. The predetermined vertical position here means that the rear cut line 94 of the held glass plate 90 coincides with the rear edge of the second dividing base 73 (rear dividing receiving 86), and the rear ear 98 is the second. The vertical position is located in the dividing groove 80. Note that when the plate glass 90 is placed on the upper surface of the second dividing table 73, the right cut line 91 and the left cut line 92 of the plate glass 90 are connected to the right edge and the left edge (the right cut receiver). The right edge of 87 and the side edge of the left divided receiver 88 are respectively coincident with each other. Further, at the same time when the dividing unit 50 places the plate glass 90 on the second dividing table 73, the second dividing table 73 stops the air blowing from the blowing holes 82, and the second lower surface suction pad device 84 has the lower surface suction pad 83. By adsorbing the lower surface of the plate glass 90, the plate glass 90 is fixed on the second dividing table 73.

  Then, even if the dividing unit 50 raises the dividing holding part 56, it returns to the original height position. This is the end of the post-cut conveyance work. Thus, the cutting unit 50 can not only cut the plate glass 90 but also can transport the plate glass 90 as in the case of the cutting unit 20. Therefore, since all the conveyance of the plate glass 90 in the cutting / cutting device 100 can be performed by the cutting unit 20 or the cutting unit 50, it is not necessary to provide a separate transport unit or the like in the cutting / cutting device 100.

[Rear left / right parting]
The rear left / right parting operation is mainly performed by the parting unit 50. After the conveying operation during the dividing, the dividing unit 50 lowers the rear dividing bar 53 and applies a force to the rear ear portion 98 of the plate glass 90 from above. Note that, as described above, since the rear parting bar 53 is positioned in front of the rear ear portion 98 in advance during the transporting operation during parting, the rear parting bar 53 is simply lowered without any special alignment. Then, a force can be applied to the rear ear portion 98. Thereby, the rear-ear part 98 of the plate glass 90 is parted.

  Thereafter, the dividing unit 50 returns to the original height position even if the rear dividing bar 53 is raised, and moves slightly upstream. The reason why the dividing unit 50 moves slightly upstream is to allow the right dividing bar 54 and the left dividing bar 55 to cover the entire right ear portion 95 and left ear portion 96, respectively. In addition, the position after the movement of the dividing unit 50 here is the dividing unit standby position described in the previous dividing operation.

  Thereafter, the dividing unit 50 lowers the right dividing bar 54 and the left dividing bar 55 at the same time, applies a force to the right ear portion 95 and the left ear portion 96 from above, and divides each from the plate glass 90. After the right ear part 95 and the left ear part 96 are divided, the right parting bar 54 and the left parting bar 55 are raised to their original height positions.

  Finally, the second lower surface suction pad device 84 stops the suction of the plate glass 90 by the lower surface suction pad 83, the second dividing table 73 resumes the blowing of air from the upper surface blow hole 82, and the plate glass 90 is cut and divided. Unload from 100. Various methods for carrying out the plate glass 90 are conceivable. For example, the plate glass 90 may be carried out by disposing a belt conveyor between the second plate-like members 81 and placing the plate glass 90 on the belt conveyor. Alternatively, the plate glass 90 may be lifted by blowing air from the blowing hole 82 of the second dividing table 73 and slid in the downstream direction to carry out the plate glass 90. Moreover, you may carry out the plate glass 90 by hold | maintaining the plate glass 90 with the parting unit 50, and moving toward a downstream direction.

  With the above, one cycle of the cutting operation, the post-cutting transfer operation, the pre-partitioning operation, the conveying operation during the division, and the rear left / right dividing operation is completed. By passing through each of these operations, each of the ear portions 95 to 98 is divided, and the plate glass 90 formed in a predetermined size is carried out to the next step (apparatus). In the present embodiment, the cutting unit 50 has been described as not operating while the cutting unit 20 is operating for the sake of easy understanding. At the same time as the work after the work, the work after the cutting work of the next cycle is performed by the cutting unit 20. Thus, an efficient cutting and dividing operation can be performed by proceeding each operation in parallel.

  The above is description about operation | movement of the cutting cutting apparatus 100 which concerns on this embodiment. In the above description, the case where the divided front ear portion 97 falls into the first dividing groove 79 and is collected by a collection box or chute (not shown) has been described. However, a film is formed below the first dividing groove 79. A peeling device may be provided, and the front ear portion 97 may be collected by the film peeling device. More specifically, when a protective film is affixed to the lower surface of the plate glass, the divided ears are hung from the film without falling. The film peeling apparatus peels off the film by utilizing the fact that the divided ears are hanging on the film. In other words, the film peeling device referred to here grasps the ear part (ear part corresponding to the front ear part 97 of the present embodiment) that is divided and hung on the film, and at the timing when the plate glass is conveyed in the downstream direction. By pulling the ear and the film, the entire film of the plate glass is peeled off. In order for such a film peeling apparatus to function, it is necessary to divide the front ear part among the ear parts to be divided before the other ear parts, and the cutting and cutting apparatus according to the present embodiment is this It is configured to satisfy the conditions. In other words, according to the cutting device 100 according to the present embodiment, the above-described film peeling device can be installed.

  As described above, the embodiments of the present invention have been described with reference to the drawings. However, the specific configuration is not limited to these embodiments, and even if there is a design change or the like without departing from the gist of the present invention. It is included in the present invention. For example, in the embodiment, the front ear part is divided by the front dividing bar and the rear ear part is divided by the rear dividing bar, but both the front ear part and the rear ear part are divided by one dividing bar. Even if constituted, it is included in the present invention.

  According to the sheet glass cutting and cutting apparatus according to the present invention, since the cutting work to the cutting work can be efficiently performed, it is useful in the technical field of the sheet glass cutting and cutting apparatus.
