度を上げることができない欠点があつた。(Prior art) As a method for inspecting the mouth of a glass bottle for defects that impair the sealing performance when capped, as shown in Japanese Patent Application Laid-Open No. 56-82404, the mouth of the glass bottle is flattened. Press the glass bottle with a suitable part and blow air at a predetermined pressure into the inside.The presence or absence of air leakage between the part and the mouth of the glass bottle is detected as a change in internal pressure, and bottles with a large pressure drop are rejected as defective bottles. method is known. However, although this method is effective as a method for inspecting smoothness defects such as protrusions and depressions on the top surface of the mouth, it is not suitable for inspecting elliptical defects where the top surface of the mouth is deformed into an ellipse while maintaining smoothness. Can not. Therefore, a mechanical inspection method has been adopted in which the glass bottle is rotated and a roller connected to a differential transformer is brought into contact with the outer peripheral surface of the mouth of the glass bottle to check its displacement. The drawback was that inspection accuracy could not be improved due to fluctuations in the rotation axis and wear of the rollers.

ことは言うまでもない。 In FIG. 1, 10 is a wide-mouth glass bottle to be inspected, and 1 is a metal lid that is brought into contact with the upper surface of the mouth of the glass bottle 10 by an appropriate lifting mechanism such as an air cylinder. . A spherical recess 2 having a diameter larger than the diameter of the bottle is formed on the lower surface of the lid 1, and an air supply hole 3 is provided through the recess 2 approximately in the center thereof. After the lid 1 is brought into contact with the upper surface of the mouth of the glass bottle 10, a predetermined amount of compressed air supplied from an air supply source 4 such as an air cylinder is supplied to the glass bottle 10 through the air supply hole 3. When introduced inside, the mouth of the glass bottle 10 is perfectly round and smooth;
If there is no gap between the mouth and the spherical recess 2 of the lid 1, the glass bottle 1 will open as shown by the solid line in FIG.
The internal pressure at 0 suddenly rises and exceeds the reference pressure P1 after a predetermined period of time. This internal pressure is compared with a reference pressure P1 supplied from a reference pressure source 6 in a comparator 5 such as a diaphragm meter, and if it is confirmed that it exceeds this, it is judged as "good".
It is determined that However, if the opening of the glass bottle 10 is deformed into an elliptical shape, it cannot come into contact with the spherical recess 2 on the entire circumference, and air leaks at the short diameter side, causing the glass bottle to The internal pressure of 10 reaches the reference pressure P1 after a predetermined period of time, as shown by the broken line in FIG.
Furthermore, although the mouth shape of the glass bottle 10 is a perfect circle,
Even if there is poor smoothness such as a protrusion on the top surface of the mouth, air will leak from between the spherical recess 2 and the internal pressure of the glass bottle 10 will still be the reference pressure.
In either case, the comparator 5 makes a "no" determination without reaching P1 . In this way, since the recess on the lower surface of the lid body 1 is spherical, the glass bottle 1
Even if 0 is slightly inclined with respect to the lid 1, the inspection accuracy will not be affected. It goes without saying that the air supply source 4 may be of a constant volume type, such as an air cylinder, or of a constant pressure type.

体の衝撃による壜口部の破損は皆無であつた。 A lid with a spherical recess with a radius of curvature of 55 mm and a diameter of 80 mm on the bottom is brought into contact with the mouth of a cup-shaped glass sake bottle with a diameter of 65 mm and an internal capacity of 200 c.c., and the air cylinder is closed. A predetermined amount of compressed air determined according to the size of the glass bottle is introduced from an air supply source into the bottle at a cycle of about 0.3 seconds per glass bottle, and after 0.3 seconds the internal pressure reaches the standard pressure of 0.1. If the pressure reached Kg/ cm2 , it was judged as "good", and if it did not reach this pressure, it was judged as "fail".
We conducted a million tests. The diameter of this glass bottle for sake should be within the range of 65mm±0.5mm, but 50 bottles were selected from among those judged to be "good".
When we randomly sampled books and measured their bottle diameters, all of them were within the above range.
When we sampled 20 out of 1286 that were judged as "failed" and measured them in the same way, all of them were 65mm.
It exceeded the range of ±0.5 mm. Furthermore, there was no damage to the mouth of the bottle due to impact from the lid.

Since it is possible to detect quality defects even if they exist, it will greatly contribute to the industry as a solution to the problems of conventional inspection methods of this type.
