The cullet produced by the folds is discharged to the outside of the main processing machine by driving the conveyor belt 74, and at the same time, the glass sheet to be supplied next is received by the cleaned new belt surface of the conveyor belt 74.

With reference to FIG. 4, the operation of the glass plate processing machine and the process from the supply of raw glass plate to the finish of processing will be sequentially described.

At the start of this glass plate processing machine, of course,
Each of the cutter wheel 35, the polishing wheel 47, the work table 19, and the glass conveying device 49 waits at the origin, that is, the start position. Note that the work table 19 has an origin at a position directly below the suction pad 56 of the glass conveying device 49. At the start position of this work table 19, the glass plate 22
The center lines of the suction pads 56 and the center line of the work table 19 which are lined up in the traveling direction of are aligned with each other.

It is regulated in the state of being positioned as shown in.

Now, as described above, when each working unit is at the origin, first, the glass sheet 22 is placed on the glass plate insertion table 5, and the start button of the glass sheet processing machine is pressed to start the glass sheet processing machine. When it is started, first, the suction pad 56A hangs down to suck the raw glass plate 22 and lift it.

From this state, the transfer frame 55 moves and the suction pad 56A
Reaches the predetermined position on the cutting table 20, the suction pad
56A hangs down, releases the suction on the glass plate 22,
Place the blank glass 22 on the cutting table 20 and attach the suction pad.

A table 20 and a glass fixed suction cup 21 corresponding to the polishing head 8 are mounted on a work table 19 which is a common moving means in the Y-axis direction, and further, the cutting head 7 and the polishing head 8 both have a common conduction at the upper part. Since they are connected by the Z-axis line shaft 33, which is a means, the cutting portion 1 and the polishing portion 2 run the same or similar movement loci in their tool portions, and perform the same angle control motion to cut the cutting loci. The polishing is performed in a manner similar to that, and the same processing mark is formed over the entire circumference.

However, the cutting head 7 has a cutter line changing device.
Since the cutter line changing device 82 is provided with a signal from the program and the cutter wheel 35 can be moved in the normal direction of the movement locus via the cutter body 36, as shown in FIG. In addition, only the cutting locus at the required part of the thread surface is slightly inward from the polishing locus approximately 0.3 to 0.6 mm.
You can change the position.

Therefore, in the yarn chamfering portion 91, the yarn chamfering is performed only by a small amount of the polishing wheel 47 hitting. In addition, the entire circumference polishing section 90
Then, by returning the line changing device 82 to the original position by a signal from the program, the cutting locus 92 and the polishing locus 93 become the same or similar, and the entire circumference polishing similar to the cutting line is performed.

That is, by operating the line changing device 82 with a signal on the program, an automobile glass having a mixed yarn surface as shown in FIG. 1 can be automatically produced.
