To do. The apparent friction coefficient μ is used to determine the rotating state of the cutter wheel 36 and the like. That is, the friction coefficient μ
Is large, it means that the cutter wheel 36 is not rotating and is sliding on the surface of the plate glass 14.
On the other hand, when the apparent friction coefficient μ is small, the cutter wheel 36 is rotated well, and the cutter wheel 36 is processing an appropriate cutting line on the surface of the plate glass 14.

Can compare the apparent friction coefficient μ obtained by the data processing unit 40 with a threshold value to determine whether the cutter wheel 36 is rotated properly. Further, the inclination of the cutter wheel 36 with respect to the traveling direction can be detected by the X-direction component force or X / Z. There are various causes for the inclination of the cutter wheel 36.

よる切線不良を防止することが可能である。(1) Insufficient angular adjustment of the device (2) Poor rotation of the bearing 32 (see FIGS. 1 and 2) (3) Wear of the cutter wheel 36 causes insufficient cutting of the cutter wheel 36 into the plate glass 14, In the case where the caster effect is not sufficiently exerted. (4) The deviation of the ridge line 36A (see FIG. 1) of the cutter wheel 36 is further defective. Further, as shown in FIG.
Is 0, the X-direction component force or X / Z is almost 0, and as the inclination θ of the cutter wheel 36 increases, the X-direction component force or the absolute value of X / Z increases. Then, if the inclination θ of the cutter wheel 36 becomes large, a cutting line defect will occur, so a threshold value of the X-direction component force or X / Z is set, and the set threshold value and the X-direction component force or X / Z absolute value. By comparing the value with the value, it is possible to prevent a cutting line defect due to the inclination of the cutter wheel 36.

The directional component force becomes unstable, for example, when the cutting pressure is unstable due to increased friction between the shaft 16 and the bearing 18, or when an abnormality occurs in the pressurizing mechanism of the cutter wheel 36. In this case, the pressing force of the cutter wheel 36 against the plate glass 14 becomes unstable, so that it is impossible to process an appropriate cutting line on the plate glass 14. Therefore, the determination unit 42 is determined by the data processing unit 40 by setting the threshold value of the instability degree of the component force in the Z direction that distinguishes whether the cutting line is properly processed or not. The data of the component force in the Z direction and the threshold value are compared to determine whether the cut line state of the plate glass 14 is good or bad.

ることができない。When the Z-direction component force fluctuates in a constant cycle, it is possible to determine the shape abnormality of the cutter wheel 36. For example, when the cutter wheel 36 is eccentric as shown in FIG. 4, when the cutter wheel 36 makes one revolution, the measurement length L in FIGS. 2 and 4 changes in a mountain-shaped curve with a maximum displacement 2e as shown by a broken line. Therefore, if the cutting line is processed by the eccentric cutter wheel 36, the component force in the Z direction (that is,
As shown in (2) of FIG. 5, the true pressing force appears in a mountain-shaped portion at a constant cycle, and an appropriate cutting line cannot be processed on the plate glass 14.

In order to prevent the cutting line from becoming unstable, the data processing unit 40 compares the data that changes in a constant cycle with the fluctuation threshold value to determine whether the concentricity of the cutter wheel 36 is good or bad. In addition, it is possible to determine whether the circularity of the cutter wheel 36 is good or bad by adopting this method. Note that FIG.
In FIG. 5, the solid line graph shows normal data of the cutter wheel 36 without eccentricity. In this case, as shown in (1) of FIG. 5, the Z-direction component force does not have a constant periodic fluctuation and is stable in the Z-direction component force. become.

In addition to the determination of the roundness and concentricity of the cutter wheel 36, the determination of local defects and local wear of the ridgeline of the cutter wheel 36, and the cutting wheel 36 such as the entrapment of foreign matter such as cullet or the catching of foreign matter It can be used to determine the abnormality of the rotating system. That is, the determination unit 42
It is possible to determine whether or not these defects are occurring by comparing the data, which is obtained by the data processing unit 40, and which changes in a constant cycle, with the threshold value. When the Z-direction component force fluctuates in a constant cycle, the data processing unit 40 obtains data in the high frequency region of approximately 5 kHz to 50 kHz, and the determination unit 42 determines the data in the high frequency region obtained by the data processing unit 40. Then, it is also possible to judge the progress state of the fine cracks generated in the cutting line.

Each of the threshold values of 1 and the respective values obtained by the detection unit 41 are compared to determine the quality of the cutting line. Then, the cutter wheel 36, the pin 35, and the like are replaced based on the determination result of the determination unit 42. In addition, as a result of the determination by the determination unit 42, if the processing conditions (cutting pressure of the cutter wheel 36, cutting speed, turning angle, etc.) can be changed or corrected, the cutter wheel 36 can be used.
The machining conditions can be changed or corrected without replacing the pin 35 or the like.

Change the turning angle of the 0 cutter. In addition, the detection unit 41
When the value of the apparent friction coefficient μ detected in step 3 is near the threshold value, the cutting pressure of the sheet glass cutting device 10 is changed to a high value so that the value of the detected apparent friction coefficient μ does not exceed the threshold value. By doing so, the cutter wheel 36 bites strongly into the plate glass 14, so that an appropriate cutting line can be processed in the plate glass 14.

It can be self-managed so that the cutting line is machined into the glass sheet 14. In FIG. 2, 46 is an amplifier and 48 is a table on which the plate glass 14 is placed.

になる。Further, by obtaining the reaction force of the cutter wheel 36, that is, the component force in the X direction, the Y direction and the Z direction, the adjustment items of the plate glass cutting device 10 are quantified and managed in addition to the above-mentioned determination. It is also possible. For example, it is possible to properly set the impact force when the cutter wheel 36 descends based on the component forces in the X direction, the Y direction, and the Z direction to prevent the occurrence of touch jamming or the like. It is possible to optimally set the switching point to the switch to obtain a true switching point irrelevant to the mechanical system delay. Further, it is possible to determine whether the swinging angle of the cutter wheel 36 and the traveling direction match, so that the swinging angle is misaligned, for example, when the cutter wheel 36 collides with an obstacle or a glass edge due to an operation error. In this case, it becomes easy to adjust the angle, and it is possible to determine that the cutting in the X direction is appropriate and the cutting in the Y direction is incorrect during the cutting line processing.

Then, the plate glass 14 may be chipped. In this case, when the cutter wheel 36 descends to the scoring start position and contacts the inclined surface, the cutter wheel 36 receives the Z component reaction force and the Y component reaction force from the inclined surface of the plate glass 14. Therefore, in order to eliminate these problems, the detection unit 41 detects the Z component reaction force and the Y component reaction force when the cutter wheel 36 descends to the cutting line machining start position, and detects the detected Z component reaction force and Y component. The Y / Z value is obtained based on the reaction force, and the Y / Z value obtained by the determination unit 42 is obtained.
The value is compared with the threshold value, and when the calculated Y / Z value exceeds the threshold value, the cutter wheel 36 is controlled so as not to travel in the arrow direction. The same control can be performed by focusing on Y only.
