(4) feature
Device for producing glass sheet 100 transports glass to X-direction by carrying device 102 on one side in the 1st checking step S3
Glass plate 10 optically detects the foreign matter for being present in the inside of glass plate 10 using check device 104 on one side.
To main surface 10a, 10b of the glass plate 10 transported by carrying device 102 blow from air knife 116a ... ejection
Air.Air by guide plate 118a ... guidance, and along X-direction guide plate 118a ... with the spatial flow between glass plate 10
It is dynamic.
On one side referring to Fig. 5, one from the 1st left air knife 116a in face of spraying and by the 1st left guide plate 118a air guided
Effect is illustrated.As shown in figure 5, from the air side that the 1st left air knife 116a sprays suck surrounding air into one side along
Guide flexure plane 119a1 flowing, and the spatial flow between guide plane 119a2 and left main surface 10a.1st left guide plate
Space between 118a and glass plate 10 is from the flow path of the 1st left air knife 116a air sprayed, and from upstream side towards downstream
Side slowly narrows.Therefore, in the space between the 1st left guide plate 118a and glass plate 10, the flow velocity of air is from upstream side direction
Downstream side slowly becomes larger.In particular, the flow velocity of air becomes most in space between guide plane 119a2 and left main surface 10a
Greatly.According to the theorem of Bernoulli Jacob, more increasing, the pressure of air more, is reduced for the flow velocity of air, therefore guide plane 119a2 and left
Space between main surface 10a becomes negative pressure relative to the space of surrounding.As a result, glass plate 10 is by the 1st left guide plate of direction

Lower place, the place is in the Z-axis direction farthest away from the Y-axis side of the clamp mechanism 112 of clamping glass plate 10 and inhibition glass plate 10
The lower guide mechanism 114 of upward movement.Therefore, the middle section in the Z-direction of the glass plate 10 transported is not to Y
In the case that axis direction is endowed any power, it is easy the minor change of the pressure around glass plate 10 due to shakes to Y direction
It is dynamic.
However, in the present embodiment, the central area of the glass plate 10 transported by carrying device 102 in the Z-axis direction
Domain is endowed the power of Y-axis positive direction and negative direction.It is identical as the size of the power of Y-axis negative direction in the size of the power of Y-axis positive direction
In the case where, the power for acting on the Y direction of glass plate 10 is balanced.Therefore, the glass plate 10 transported is not easy in the Z-axis direction

The becoming stable of air-flow of main surface 10a, therefore the vibration of the Y direction of glass plate 10 can be reduced.
It is vibrated in addition, if passing through the glass plate 10 that carrying device 102 transports to Y direction, then the line of check device 104
The focal position of the camera 122a of sensor 122 deviates, therefore is present in the detection accuracy drop of the foreign matter of the inside of glass plate 10
It is low.In addition, it is the coke of camera 122a in ± 3mm situation below that the focal zone of the camera 122a of on-line sensor 122 is shorter
The more demanding precision in point position, therefore the detection accuracy for being present in the foreign matter of the inside of glass plate 10 reduces.Therefore, because glass
Glass plate manufacturing device 100 can reduce the vibration of transported glass plate 10, and by the amplitude of the vibration of the Y direction of glass plate 10
It controls in 1mm hereinafter, therefore can inhibit the detection accuracy reduction for being present in the foreign matter of inside of glass plate 10.
