Definitions

  • the carrier 20 before sandwiching and pressing the glass sheet 2 between the upper mold 30 and the lower mold 40, the carrier 20 is retracted from the press zone Z2 to the retraction zone Z3.
  • a mechanism 27 and a slide mechanism 29 are provided.
  • the upper mold 30 can enter the movement path of the carrier 20, and the glass plate 2 can be sandwiched between the upper mold 30 and the lower mold 40 and pressed. .
  • the first elevating mechanism 37 lowers the upper mold 30 to bring the lower surface 31 of the upper mold 30 close to the glass plate 2 until there is a slight gap (step S102). . Subsequently, the suction device 32 sucks the glass plate 2 onto the upper mold 30 (step S103). Next, as shown in FIG. 2B, the first elevating mechanism 37 raises the glass plate 2 together with the upper mold 30 (step S104).
  • the slide mechanism 29 lifts and removes the carrier 20 from the conveyor 25 in the press zone Z2, and horizontally slides the removed carrier 20 from the press zone Z2 to the evacuation zone Z3 (step S105).
  • the slide mechanism 29 slides the empty carrier 20 below the carrier 20 previously lifted by the second lifting mechanism 27 .
  • the first elevating mechanism 37 lowers the glass plate 2 together with the upper mold 30, bringing the glass plate 2 closer to the lower mold 40 until a slight gap is created (step S106). Subsequently, the suction device 32 releases the suction of the glass plate 2 to the upper mold 30 (step S107). Next, as shown in FIG. 3A, the first elevating mechanism 37 further lowers the upper mold 30 to sandwich and press the glass plate 2 between the upper mold 30 and the lower mold 40 (step S108).
