  • the channel brush 21 is bent upstream of the first main surface Ga of the glass sheet G (more specifically, in the conveying direction with respect to the folding bar 11) while bending the brush 21a. This is a region on the side, and abuts with a necessary part to be a product).
  • the suction pad 41 also abuts the first main surface Ga of the glass sheet G (more specifically, an area on the downstream side in the transport direction with respect to the folding bar 11 and is discarded) at the lower end thereof. Thereby, the plate glass G is pressed from above by the channel brush 21 and the suction pad 41, and the posture at a predetermined position in the manufacturing apparatus 1 is maintained.
  • the suction pad 41 starts the suction operation immediately after coming into contact with the plate glass G and presses the plate glass G with the downstream side in the transport direction of the plate glass G being sucked.
  • the nozzle 31 also descends as the channel brush 21 descends. At this time, the shutter plate 38 of the nozzle 31 is still held in the “standby mode” state, and the suction pressure of the dust collecting mechanism 30 is suppressed. It has become a state.
  • the shutter plate 38 of the nozzle 31 is immediately switched to the “dust collection mode” state, and the dust collection mechanism unit 30 exhibits a predetermined suction pressure.
  • the opening / closing valve 37B of the damper 37 is switched to the “closed” state, and the inside of the header tank 34 is closed to the outside through the damper main body 37A.
  • produce at the time of the plate glass G breaking are attracted
  • the protective sheet S is provided on the lower surface of the plate glass G, and a part of the protective sheet is exposed to the vicinity of the nozzle 31 of the dust collecting mechanism 30, but the channel brush 21. Further, since the suction pad 41 is pressed from above through the plate glass G, a part of the protective sheet S is not sucked into the nozzle 31 of the dust collecting mechanism 30.
  • the folding bar 11 stops rising and then starts to descend. Then, as shown in FIG. 4D, when the folding bar 11 reaches the “downward standby position” again, the folding bar 11 stops descending.
  • the shutter plate 38 of the nozzle 31 is immediately switched to the “standby mode” state, and the suction pressure of the dust collecting mechanism 30 is again suppressed.
  • the opening / closing valve 37B of the damper 37 is also switched to the “open” state, and the inside of the header tank 34 is opened to the outside through the damper main body 37A.
  • the channel brush 21 starts to rise. Further, as the channel brush 21 rises, the suction pad 41 also starts to rise while the unnecessary portion of the plate glass G is sucked.
  • the state of the protective sheet S is completely released from the pressed state by the channel brush 21 and the suction pad 41.
  • the shutter plate 38 of the nozzle 31 is already in the “standby mode”. Since the suction pressure of the dust collection mechanism portion 30 is suppressed, the nozzle 31 of the dust collection mechanism portion 30 does not rise while sucking a part of the protective sheet S and being rolled up. However, even when the shutter plate 38 of the nozzle 31 is in the “standby mode” state, the suction pressure of the dust collecting mechanism portion 30 is not completely stopped but is exerted in a suppressed state. For example, glass powder or the like that has already been sucked and temporarily stored in the header tank 34 does not fall down from the nozzle port 31B of the nozzle 31.
  • the suction pad 41 moves to a predetermined location (such as a discharge conveyor) while the unnecessary portion of the plate glass G is sucked, and the unnecessary portion of the plate glass G is transferred. After that, it moves again to the “upper standby position” and stops.
  • a predetermined location such as a discharge conveyor
  • the broken plate glass G is unloaded from the manufacturing apparatus 1.
  • the operation procedure of the manufacturing apparatus 1 is temporarily ended, and the process waits until another new plate glass G is put into the manufacturing apparatus 1.
  • the plate glass manufacturing method and apparatus according to the present invention can be used as a technique for sucking and removing glass powder generated when cleaving a plate glass.
