A liquid such as a nutrient is filled in a transparent container such as a glass container such as a glass bottle or a plastic container. Such filling and sealing (sealing), and label attachment, etc. are automatically performed one after another on a sanitary controlled transport path. On the transport path,
Various tests are also performed. Check that the container is not deformed, distorted or cracked, the liquid filling amount is as specified, the sealing is done correctly, the label to be attached is in the predetermined position,
And so on. As another important inspection example, there is a foreign matter inspection for inspecting whether foreign matter is mixed in the liquid.

効果について説明する。When capturing an image of a foreign object with an imaging camera, the lens effect of the transparent container may make it difficult to detect the foreign object depending on the position, or may detect the foreign object as a different shape. . The lens effect of such a transparent container will be described.

る。FIG. 2 shows an image forming (focus) lens 2 at a position P 2 immediately before an image pickup surface P 1 of a CCD camera 1 for picking up a surface.
An image of the transparent container 3 is to be taken through the imaging lens 2. The transparent container 3 is shown as viewed from above. FIG. 2A shows an example in which the foreign matter 4a exists in front of the center of the container and the foreign matter 4b exists at the upper end. This is C
When the image was picked up by the CD camera 1, an image 10A was obtained. In the image 10A, the image of the foreign substance 4a is captured together with the image of the container 3, but the image of the foreign substance 4b is not captured. The foreign matter 4b became a blind spot due to the lens effect of the transparent container and could not be imaged. The hatched portions at the upper and lower ends are the imaging blind spot regions E 1 and E 2 due to the lens effect. The occurrence of the blind spot regions E 1 and E 2 is due to refraction of the optical path. That is,
When viewed from the lens 2, the optical path is refracted inside at the end points 3 a and 3 b of the container 3, and the container area E outside the end points 3 a and 3 b.
1 and E 2 completely become the imaging blind spot as shown by the diagonal lines.

This is an example where d exists in the upper blind spot area. Foreign matter 4d is shown in FIG.
No image is captured as in (a). On the other hand, the foreign substance 4c has a small round shape, but is transformed into a linear image like a captured image 4c '. The reason why the linear image 4c 'appears is that the optical path is refracted from the end points 3c and 3d of the container 3 to the inside of the container. As a result, the foreign matter 4c advances to the imaging lens 2 through this optical path, and the enlarged linear image 4c
c 'is that obtained on the imaging plane P 1. An object of the present invention relates to a foreign matter inspection apparatus and system capable of eliminating a lens effect and eliminating foreign matter detection and foreign matter detection distortion at any position in a container.

状歪みを受けずに、正しい形状画像となる。FIG. 1 is a diagram illustrating the principle of the present invention. An imaging camera, for example, a CCD camera 1 is provided with an imaging lens 2 on a front surface thereof, receives parallel rays from a rear surface illumination unit 6, receives light transmitted through the glass container 3 in a plane, and images the surface. Here, a correction lens 5 was provided immediately adjacent to or in contact with a glass container (for example, an ampoule bin or a vial bin). The correction lens 5 has a concave portion 5 a facing the outer convex shape of the glass container 3. That is, there is a relationship between the outer shape and the unevenness. The concave portion 5a is brought into contact with or close to the container 3. The material needs to have the same or similar refractive index as the glass container 3. For example, the glass material is made of the same material as the glass container 3. When the correction lens 5 is provided, the optical path does not have discontinuous refraction as shown at the end points 3a to 3d as shown in FIG. 2 and becomes an optical path that continuously enters the inside along the circular outer shape. As a result, such blind area E 1, E 2 is no longer shown in FIG. 2, and FIG. 2 (b) linear distorted image 4c as shown in 'also eliminated. FIG. 3 shows an example of removing the lens effect by the correction lens 5. In FIG. 3A, the refraction of the optical path is eliminated by the correction lens 5, and the optical path becomes a straight optical path. As a result, the foreign matter 4b can be correctly imaged in addition to the foreign matter 4a. However, the position of the foreign substance 4b is upside down. In FIG. 3B, the foreign matter 4c is not subjected to linear distortion by the correction lens 5, and a correct shape image is obtained.

Although the imaging of the transmitted light has been described, the imaging of the reflected light can be performed by changing the arrangement of the illumination unit 6. Although a glass container is used, the present invention can be applied to a transparent container including a plastic container. As the shape, a circular or elliptical cross-sectional shape is preferable, but there is only an advantage that a correction lens is easily formed, and other shapes are not denied. Further, an example in which the filling liquid and the container color are colorless and transparent is preferable, but there may be application examples other than colorless and transparent. In addition, although the liquid is in a stationary state, it is needless to say that the present invention can also be applied to imaging when the liquid is rotated.
