    • [PROBLEMS] To improve the inspection accuracy and to detect all defects including a top line, a top bubble, a defective top flatness, and a top dimple only by means of a single inspection device. [MEANS FOR SOLVING PROBLEMS] When there is one region where the edge signal exceeds an edge signal threshold (EL), the address generated by adding a predetermined offset value (OFS) to the address (inspection gate edge address GE) where the edge signal first reaches the edge signal threshold (EL) is used as the inspection gate start position address (GES); when there are two regions where the edge signal exceeds the edge signal threshold (EL), the address generated by adding the predetermined offset value (OFS) to the address (inspection gate edge address GE) in the second region where the edge signal first reaches the edge signal threshold (EL) is used as the inspection gate start position address (GES). Therefore, an inspection gate which is the region to be inspected can be properly made, and top line/bubble inspection of the mouth top can be carried out accurately without being influenced by various types of noise.
    • [问题]提高检查精度并且仅通过单个检查装置检测包括顶线,顶部气泡,有缺陷的顶部平坦度和顶部凹坑的所有缺陷。 解决问题的手段当存在边缘信号超过边缘信号阈值(EL)的一个区域时,通过将预定偏移值(OFS)加到地址(检查门边缘地址GE)而产生的地址,其中边缘信号 首先达到边缘信号阈值(EL)用作检查门起始位置地址(GES); 当存在边缘信号超过边缘信号阈值(EL)的两个区域时,通过将边界信号首先到达的第二区域中的地址(检查门边缘地址GE)相加预定偏移值(OFS)而产生的地址 边缘信号阈值(EL)用作检查门开始位置地址(GES)。 因此,可以适当地制造作为检查区域的检查门,能够精确地进行嘴顶的顶线/气泡检查,而不受各种噪声的影响。

    • To allow inclination of a sealing surface of a bottle mouth portion to be correctly inspected even when the bottle wobbles or is inclined due to rotation of the bottle while the bottle is being rotated on an inspection table. Two points G and H on the sealing surface of a bottle mouth are detected in a mouth portion image taken by a mouth portion image taking means, two points M and N at a bottom end of the bottle are detected in a base portion image taken by a base portion image taking means at the same time as the mouth portion image is taken, and sealing surface inclination of the bottle in a vertically standing position is calculated by subtracting inclination of the two points M and N of the base portion from inclination of the two points G and H of the mouth portion. This allows inclination of the sealing surface of the bottle mouth portion to be correctly inspected even when the bottle wobbles or is inclined.
    • 即使当瓶子在检查台上旋转时,即使当瓶子由于瓶子的旋转而摆动或倾斜时,也允许正确地检查瓶口部分的密封表面的倾斜。 在口部图像摄取装置拍摄的口部图像中检测到瓶口密封表面上的两点G和H,在拍摄的基部图像中检测到瓶子底端处的两点M和N 在拍摄口部图像的同时拍摄基部图像拍摄装置,并且通过从基部图像的倾斜减去基部的两点M和N的倾斜来计算瓶子在垂直站立位置的密封表面倾斜度 嘴部的两点G和H. 由此,即使瓶摇动或倾斜,也能够正确地检查瓶口部的密封面的倾斜。

    • To allow so-called sealing surface waving, which is a defect in that a part of sealing surface of a bottle mouth portion has wave-shaped recesses, to be highly precisely detected. Two points A and B on the sealing surface of the bottle mouth portion are detected in a mouth portion image taken by an image taking means, a line segment c, which connects A and B to each other, is obtained and an intersection D, at which a vertical line d that passes through an arbitrary intermediate point C of the line segment c and the sealing surface of the mouth portion intersects each other, is obtained, a difference T between the intersection D and the intermediate point C is calculated, and whether or not the glass bottle is good is determined in accordance with a value of T. The presence of sealing surface waving in the sealing surface of the bottle mouth portion increases the difference between the intermediate point C of the line segment c and the intersection D, at which the vertical line d that passes through C and the sealing surface of the bottle mouth portion intersect each other. Thus, the difference T between C and D is calculated, and the following determination can be performed: if T falls within a specified range, the bottle is determined to be good; otherwise, the bottle is determined to be bad because of the presence of a sealing surface waving defect.
