  Hereinafter, the glass plate support of the cutting part is referred to as a cutting table, and the glass plate support of the grinding part is referred to as a grinding table.

  Conventionally, a cut glass plate that has been conveyed from the cutting part to the grinding part through the split part is ground in this grinding part, and the processing dimensions of this ground glass sheet are automatically measured, and this measured value There is a glass plate processing apparatus described in International Publication No. WO2004 / 039538 as a glass plate processing method and glass plate processing apparatus that automatically corrects the cutting amount of the grinding wheel. This glass plate processing apparatus includes a cut line forming means for forming a cut line in the glass plate, a folding means for breaking the glass plate on which the cut line has been formed by the cut line forming means, and a folding means for breaking the glass plate. A grinding means having a disk-shaped grinding wheel for contacting the periphery of the glass plate and grinding the periphery, a detecting means for detecting the position of the periphery of the glass plate ground by the grinding means, and a grinding means. A setting value that sets a desired value (reference value) indicating the desired position of the peripheral edge of the ground glass plate, a detection value that indicates the position of the peripheral edge of the glass plate detected by the detection means, and a setting value that is preset by the setting means Based on the above, there are provided correcting means for correcting the position of the grinding wheel relative to the incoming glass plate, and conveying means for sequentially conveying the glass plate to the cutting line forming means, the folding means and the grinding means.

  The glass plate 5 is conveyed by the above-mentioned distance for each reciprocating movement of the reciprocating table 80 controlled by NC control. In particular, the glass plate 5 is conveyed in a straight line through the cutting table 12, the belt conveyor 70, and the grinding table 13. The reciprocating direction of the reciprocating table 80 is the above-described conveying direction of the glass plate 5 and also the X-axis direction.

  The operation of the glass plate processing apparatus 1 as described above, that is, the operation of the processing operation will be described.

  Immediately before the machining operation, the cutting head 9 and cutting table 12 of the cutting unit 2, the folding devices 71 and 71 of the folding unit 4, the grinding head 10 and the grinding table 13 of the grinding unit 3 are all waiting at the origin position. . And the glass plate conveying apparatus 6 has the reciprocating table 80 located at the return end.

  This is the position where the glass plate 5 is received. Then, the suction cup lifting device 82 of the glass plate conveying device 6 is directly above the entrance table 7, and the suction cup lifting device 83 is directly above the glass plate support base of the cutting unit 2, and the belt conveyor 70 of the glass plate lifting device 84 is Further, the suction cup lifting device 85 is positioned directly above the glass plate support of the grinding unit 3.

  Along with the processing operation start command, each suction cup lifting device 82, 83, 84, 85, lowers the suction cup 86 at the same time to suck and lift the glass plate 5, and the reciprocating base 80 starts to move forward. In each suction cup lifting device 82, 83, 84, 85, the suction cup 86 adsorbs the glass plate 5, and moves forward as a unit to carry the glass plate. When the reciprocating base 80 reaches the forward end, the suction cup lifting / lowering device 82 is directly above the cutting table 12 of the cutting unit 2, and the suction cup lifting / lowering device 83 is directly above the belt conveyor 70 of the folding table 4. The device 84 is located directly above the grinding table 13 of the grinding section 3 and the glass plate lifting device 85 is located above the take-out conveyor. At the same time, the suction plate lifting devices 82, 83, 84, 85 simultaneously lower the suction plate 86 for suctioning the glass plate, release the suction, and pass the glass plate 5 to each. At the same time, the sucker 86 that has been emptied is lifted. Then, the reciprocating table 80 is moved together with the empty suction cup 86 to return to the return end.

  Next, for a single glass plate 5, a description will be given of the forward conveyance from entering to each processing unit and the processing at each processed processing unit.

  When the operation of the glass plate processing apparatus 1 starts, the glass plate conveying device 6 operates. That is, the suction cup 86 descends on the entrance table 7, sucks and lifts the glass sheet 5 on the entrance table 7, and the reciprocating table 80 moves forward (NC controlled). When the suction cup 86 adsorbing the base glass plate 5 reaches the cutting table 12 of the cutting portion, the suction cup 86 is lowered and sucked and released, and the base glass plate 5 is placed on the cutting table 12. Then, the sucker 86 that has been emptied rises and the reciprocating base 80 moves backward, so that the empty suction cup 86 returns to the entrance table 7 again. Instead, a suction cup 86 corresponding to the cutting portion 2 is returned to the cutting portion 2. At the same time, in the cutting section 2, the cutting head 9 and the cutting table 12 mounted on the base glass plate are NC controlled and the cutter wheel forms a cut line on the base glass plate. When this cut line formation is completed, the cutting table 12 returns to the origin. Then, the returned suction cup 86 is lowered, sucked and lifted by the raw glass plate 5 with a severing line, and conveyed toward the folding unit 4 by the forward movement of the reciprocating table 80 (NC controlled).

  When reaching the folding part 4, the suction cup 86 descends, sucks and releases, and places the cut-lined glass plate 5 on the belt conveyor 70.

When the cutting line 2 and the grinding part 3 are cut and ground, the glass plate transport device is operated and the reciprocating table 80 moves forward (NC controlled). As a result, the suction cup 86 that has been waiting to lift the cut glass plate 5 in the split part 4 moves forward to the next grinding part 3.

  When it reaches directly above the grinding table 13 of the grinding part 3, the suction cup 86 descends and is released by suction, and the cut glass plate 5 is placed on the grinding table 13. Then, the suction cup 86 corresponding to the empty folding part 4 rises and returns to the folding part 4 by the backward movement of the reciprocating base 80.

  The grinding table 13 that has received the placement of the cut glass plate 5 on the upper surface sucks and fixes the cut glass plate horizontally. Then, the grinding table 13 and the grinding head 10 are moved under NC control, and the peripheral surface of the cut glass plate is ground by the grinding wheel 58 of the grinding head 10. When the grinding process is completed, the grinding table 13 returns to the origin. At the same time, the suction cup 86 corresponding to the grinding portion 3 is lowered, and the ground glass plate 5 is sucked and lifted. The ground glass plate 5 reaches the take-out conveyor 8 again by the forward movement of the suction cup 86 together with the reciprocating table 80, and is placed on the take-out conveyor 8 by lowering the suction cup 86 and releasing the suction. Then, the finished glass plate 5 is removed.
