  The glass plate folding machine 1 performs the folding work on the glass plate 2 as follows.

  First, the glass plate 2 previously provided with the planned split line (main cutting line) 221 is placed at an accurate position by the endless belt 211. In addition, you may make it form such a folding planned line 221 with the glass plate folding machine 1 of this example.

  When one split is completed, the vacuum sucker devices 158 and 163 already lowered by the operation of the air cylinder devices 156 and 161 are operated, and the glass already broken on the endless belt 3 by the vacuum sucker device 158 is operated. The glass plate 2 to be folded next on the endless belt 211 is sucked by the vacuum sucker device 163 and then the air cylinder devices 156 and 161 are operated, and the vacuum sucker device 158 operates the endless belt 3. The glass plate 2 to be broken is lifted on the endless belt 211 by the vacuum suction cup device 163.

  After lifting, the electric motor 166 of the reciprocating mechanism 153 is operated to move the movable table 155 forward, and the already broken glass plate 2 lifted by the vacuum suction device 158 is outside the region 5 surrounded by the support member 4. Then, the glass plate 2 which is unloaded onto the endless belt 212 and lifted by the vacuum suction cup device 163 and to be broken is loaded into the region 5 on the endless belt 3 and surrounded by the support member 4.

  During the carry-out and carry-in operations, when the motor 191 is operated with the glass plate 2 being lifted, and the endless belt 3 travels in the direction A, the folding remaining on the upper portion of the endless belt 3 remains. The split cullet is transported in the direction A along with the travel of the endless belt 3 and discharged. After discharging the cullet, the operation of the motor 191 is stopped and the traveling of the endless belt 3 in the A direction is stopped.

  After carrying out and carrying in, the air cylinder devices 156 and 161 are re-actuated, the vacuum sucker devices 158 and 163 are lowered, the vacuum sucker devices 158 and 163 are lowered to a predetermined position, and then the vacuum sucker devices 158 and 163 are sucked. The operation is stopped, and the glass plate 2 that is broken on the endless belt 212 by the vacuum suction device 158 is placed on the endless belt 3 by the vacuum suction device 163. Thereafter, the air cylinder devices 156 and 161 are reversely operated, the vacuum sucker devices 158 and 163 are raised, and the electric motor 166 of the reciprocating mechanism 153 is reversely operated to return the movable table 155 to return the vacuum sucker. The device 163 is moved onto the endless belt 211, and the vacuum suction device 158 is moved onto the endless belt 3.

  During the reciprocating motion of the vacuum sucker devices 158 and 163, the glass plate 2 to be broken next is carried into a predetermined position by the operation of the endless belt 211.

  When the vacuum sucker devices 158 and 163 are returned to their original positions, the air cylinder devices 156 and 161 are restarted, the vacuum sucker devices 158 and 163 are lowered, and the vacuum sucker devices 158 and 163 are moved to predetermined positions. , The glass plate 2 placed on the upper end of the endless belt 3 is pressed against the endless belt 3 by the vacuum suction cup device 158 with air elastic force based on the air cylinder device 156, and the air cylinder device 161 is also pressed. The glass plate 2 placed on the endless belt 211 is pressed against the endless belt 211 by the vacuum suction cup device 163 with the air elastic force based thereon.

  As a result, the glass plate 2 placed on the upper portion of the endless belt 3 is sandwiched between the vacuum sucker device 158 and the receiving plate 201 with the endless belt 3 in between, and firmly placed on the upper portion of the endless belt 3. It will be held and fixed.

  Thereafter, the motors 59 and 59a and 72 and 72a are operated to move the glass plate receiving devices 7 and 7a in the X and Y directions so that the glass receiving surfaces 6 and 6a are disposed under the cutter wheels 92 and 92a. At the same time, the motors 114 and 114a and 135 and 135a are operated to move the splitting devices 9 and 9a in the X and Y directions, and the cutter wheels 92 and 92a are moved in the radial direction starting from the planned split line 221. When the cutter wheels 92 and 92a move from the planned split line 221, the air cylinder devices 89 and 89a are simultaneously operated to bring the cutter wheels 92 and 92a into contact with the glass plate 2, thereby causing the cutter wheels 92 and 92a to move. An end cut line (auxiliary cut line) 222 is formed on the glass plate 2.

  During the formation of the end cut line 222, the motors 94 and 94a are operated so as to direct the cutting edges of the cutter wheels 92 and 92a in the end cut line forming direction. During the formation of the end line, the push rods 88 and 88a are lifted without contacting the glass plate 2.

  When one end cut line 222 is thus formed, the splitting devices 9 and 9a and the glass plate receiving devices 7 and 7a are moved to the next end cut line forming position, and the cutter wheels 92 and 92a are cut in the region 5. Each line is formed. During the end cutting line formation, the cutter wheels 92 and 92a are moved so that the fixed support surfaces 26 and 26a and the movable support surfaces 25 and 25a receive the pressing force of the cutter wheels 92 and 92a via the glass plate 2 and the belt 3. The glass plate receiving devices 7 and 7a are moved correspondingly.

  When the end line formation is completed, the air cylinder devices 89 and 89a are then operated to raise the cutter wheels 92 and 92a to release the contact between the cutter wheels 92 and 92a and the glass plate 2, while the cylinder device 35 And 35a are actuated to lower the movable receiving members 29 and 29a to form steps 46 and 46a around the fixed support surfaces 26 and 26a.

  Then, the motors 59 and 59a and 72 and 72a are operated so that the steps 46 and 46a are positioned on the planned split line 221 and the fixed support surfaces 26 and 26a are always positioned inside the planned split line 221, and the glass plate The receiving devices 7 and 7a are moved in the X and Y directions, and the motors 114 and 114a and 135 and 135a are operated to move the pushing and dividing devices 9 and 9a in the X and Y directions. It is always located outside the line 221.

  During this movement of the glass plate receiving devices 7 and 7a and the push splitting devices 9 and 9a along the planned splitting line 221, the air cylinder devices 85 and 85a are operated at the necessary places to lower the push rods 88 and 88a, thereby making the glass. The glass plate 2 is pressed along the planned split line 221 while being brought into contact with the outside of the planned split line 221 of the plate 2.

  When the above-described pushing and splitting is completed and the glass plate 2 is obtained that is broken along the planned breaking line 211, the cylinder devices 35 and 35a are reversely operated to make a step 46 around the fixed support surfaces 26 and 26a. Then, the movable receiving members 29 and 29a are raised so that the fixed support surfaces 26 and 26a and the movable support surfaces 25 and 25a are flush with each other, and the above operation is repeated.

  In the glass plate folding machine 1 using the glass plate receiving devices 9 and 9a, the fixed support surfaces 26 and 26a and the movable support surfaces 25 and 25a are flush with each other while the end cutting lines are formed by the cutter wheels 92 and 92a. In order to support the glass plate 2 from below through the belt 3, the relative positioning of the glass plate receiving devices 9 and 9a with respect to the cutter holes 92 and 92a is slightly shifted, and the cutter holes 92 and 92a are, for example, movable supported. Even if the glass plate 2 is supported from below by the movable support surfaces 25 and 25a even if the upper surfaces 25 and 25a are arranged, the end cut line 222 is formed as desired. During the splitting of the glass plate 2 by 88a, in order to form the steps 46 and 46a, the glass plate 2 is reliably split along the planned splitting line 211. Door can be.

  In addition to forming the end line, the splitting line 211 may be formed by the splitting devices 9 and 9a of the glass sheet splitting machine 1. In this case, the cutter holes 92 and 92a and the like can be omitted.

  Furthermore, in the specific example described above, a pair of glass plate receiving devices 7 and 7a, a pair of moving devices 8 and 8a, a pair of splitting devices 9 and 9a, and a pair of moving devices 10 and 10a are provided. However, instead of this, only one piece or three or more pieces may be provided to constitute a glass plate folding machine.
