At the same time, the glass plate holder 21d is placed at the front and rear edges to start the polishing position p4. Thereafter, the glass plate is lowered by the lifting device 24, whereby the glass plate 2 is lowered and placed on the glass 122160.doc -20-200900199 plate holding body 2ld, # by the glass plate holding body 2ld The absorbing body μ is actuated to suck (4) the mounted panel 2 and is reliably held so as not to cause displacement. After the glass plate 2 is suction-held by the glass plate holding body 21d, the glass plate holding body holding the (4) (4) 2 is called into the direct drive forward stroke by the direct transmission mechanism 23'. In the direct drive forward stroke, the second grinding device, the moving device 78, simultaneously controls the following mechanism: the moving mechanism, which causes the polishing heads 9 and 1 to be respectively attached to the glass plate holding body 2U by numerical control. The forward direction of the direct drive is moved in a direction parallel to each other. The turbulence mechanism 'by the numerical control respectively moves the polishing heads 9 and 10 in a direction orthogonal to the direct drive advancing direction of the glass plate holder 21d; And a linear conveying mechanism that reciprocates the glass plate holding body 2!d by numerical control; thereby, the surface contacts of the polishing heads 9 and 1 and the glass plate 2 (machining contacts) The plane coordinates are moved so that the polishing heads 9 and 10 are obliquely cross-sectioned to the glass sheet conveying path. That is, while the grinding wheel 53 of the grinding head 9 is brought into contact with the trailing edge 8, the grinding wheel of the polishing head is brought into contact with the front edge 7 and the front edge 7 and the rear edge 8 are simultaneously polished as shown in Fig. 6. After the polishing head 9 finishes the polishing of the front edge 7 and the rear edge of the glass sheet 2, the grinding wheel 53 of the polishing head 9 is raised by the lifting device 56 of the polishing head 9 to a higher than glass above the glass plate receiving frame 41. At the position of the plate 2, and after ascending, it is returned by the moving device 78 to a position where the grinding of the trailing edge 8 of the glass sheet 2 is started. The polishing head 1 is also returned to the position where the edge 7 of the glass sheet 2 is first polished by the lifting device 56 and the moving device 79.

The peripheral edge 4 of the glass sheet 2 is ground by the polishing apparatus 1 of the glass plate in this manner. The linear transport mechanism 3 includes a glass plate holder 2 1 that is arranged at a fixed interval and that is directly driven to reciprocate, and is provided with a glass plate receiving frame so as to be able to be lifted and lowered through the glass plate holder 21 41. The glass sheet 2 in the linear transport which is adsorbed and held in the process before the glass sheet holding body 2 1 is received and supported by the glass sheet receiving frame 4 ι at the end of the forward stroke. When the glass sheet is received by the frame 41 in the raised position, the glass sheet 2 enters the retracting stroke, and the next glass sheet holding body 21 is returned below the glass sheet 2. When the next glass sheet holder 21 is returned to the end, the glass sheet receiving frame 41 is lowered, and the glass sheet 2 is transferred to the glass sheet holding body 21. In the above manner, the glass sheet 2 is transferred to the upper glass sheet holding body 21 one by one, and is continuously carried forward. Therefore, the glass sheet 2 is adsorbed and held by the glass sheet holding body 21, and the glass sheet holding body 21 and the glass sheet receiving frame 41 are alternately and continuously adsorbed, so that it can be accurately conveyed forward without being displaced. The glass plate 2 is sucked and held by the aligned glass plate holder 21, and is simultaneously polished by the first polishing device and the second polishing device during forward conveyance, so that the polishing process can be performed efficiently. Further, in particular, in the second polishing apparatus, the X moving mechanism, the γ moving mechanism, and the linear conveying mechanism 3 are synchronously controlled to make the joints of the polishing heads 9 and 10 and the glass plate 2 flat. The coordinates are moved, so that the polishing heads 9 and 10 can be inclined to cross the glass plate linear conveying passage, wherein the X moving mechanism causes the polishing heads 9 and 10 to be numerically controlled in a direction parallel to the direction in which the glass sheet holding body 21 advances to convey the glass sheet. The γ moving mechanism moves the polishing heads 9 and 1 in a direction orthogonal to the forward direction of the glass sheet 2 by numerical control; and the linear conveying mechanism 3 is numerically controlled

The polishing heads 9 and 10 are reciprocated. Therefore, the conveyed glass plate 2 enters the next grinding step in the middle, so that it is not necessary to rotate 9 turns. Or the glass plate 2 can be positioned again, so that the installation area of the device can be reduced, and the overall device construction itself is relatively simple. Further, in the second polishing apparatus, when an input program is created, the polishing head, the γ moving mechanism, and the linear conveying mechanism are simultaneously controlled by drawing, and the polishing head 9 or the grinding wheel of the polishing head 9 is transported in a phantom line. The corner of the glass plate 2 is cut by the trajectory, and the front edge and the rear edge of the glass plate 2 can be ground, and the four corners can be cut.
