The table 7 is rotated by a rotating mechanism 8 which will be described in detail later, for example, in one direction at 1200 to 1500 rpm, and then temporarily stopped before the inspection position A. When the stop time elapses, the mounting table 7 is rotated in the reverse direction at 300 rpm by the rotating mechanism 8 and passes through the inspection position A in this reversed state, during which two sets of inspection means 9A and 9B are used to detect the container. The liquid level of the filling liquid in 2 and the foreign matter mixed in the filling liquid are inspected. In this case, the inspection means 9A located on the front side in the transport direction of the container 2 starts the inspection after the reverse rotation by the mounting table 7 is started.

Therefore, one inspection means 9A performs the follow-up operation for one container 2 three times, and the image-taking is performed four times for each follow-up operation, so that images for 12 times can be obtained. Since this is the same for the other inspection means 9B, a total of 24 images can be obtained for one container 2.

At this time, since the follow-up mirrors 31A and 31B are reciprocally rotated in the follow-up section that is substantially the same as the case where one container 2 is followed, for example, three containers are followed and a total of 12 images are displayed. After that, the follow-up section of each follow-up mirror 31A, 31B is shortened compared with the case where each follow-up mirror 31A, 31B is returned to the start position quickly and all the following three new follow-up containers are made to follow. Therefore, it is possible to reduce the distortion of the image due to the lengthening of the following section.

Further, the signals from the video cameras 33A and 33B are input to the determination circuits 34A and 34B (FIG. 2), respectively. Since the determination circuits 34A and 34B have the same configuration, only one determination circuit 34A will be described. In FIG. 4, the analog signal from the video camera 33A is converted into a digital signal by the A / D converter 37. It is converted and input to four binarization circuits 38, 39, 40 and 41 in this embodiment.

The inspection area setting unit 47 sets a predetermined inspection area for each of the three containers 2 photographed at the same time. As shown in FIG. 5, the inspection area setting unit 47 sets the liquid level height. The liquid level area 48, which is the liquid level of the filling liquid in the container 2, is input to the determination unit 43, and the upper foreign matter determination unit 44 includes an upper area 49 above the filling liquid excluding the area 48.
The middle foreign matter determination unit 45 is input with the middle area 50 of the central portion of the filling liquid, and the lower foreign matter determination unit 46 is input with the lower area 51 of the lower portion of the filling liquid.
At this time, the areas 48 to 51 are set to slightly overlap each other.

The liquid level determination unit 43 extracts the signal of the liquid level area 48 set by the inspection area setting unit 47 from the signals binarized by the binarization circuit 38, and extracts the signal from the extracted signal. Compare the obtained detected value with a predetermined reference value,
It is determined whether or not the liquid level of the container has a predetermined height.

At this time, the reference value set in advance by the liquid level height determination unit 43 is
It is set on the basis of the liquid surface that causes the curved surface. That is, when a curved surface is generated on the liquid surface of the filling liquid, generally a rhombus-shaped portion is generated in the filling liquid with little foaming (see FIG. 6), and bubbles above the liquid surface are generated in the filling liquid with many foaming. Since the part of ∘ becomes easy to shine, a part shining in a substantially disc shape is generated (see FIG. 7). Therefore, the shining portion is measured in advance according to the type of the filling liquid and the rotation speed thereof, and the height of the central portion of the shining portion is set as a reference value, for example.

On the other hand, when detecting the height of the central part of the shining part from the extracted signal, as shown in FIG. 5, a vertical line O 1 along the axis of the container 2 and two vertical lines in the vicinity thereof are detected. The height of the central part of the above-mentioned shining part is detected along the lines O 2 and O 3, and if at least one of the detected values matches the above reference value, it is determined that the liquid level is appropriate. I have to. This is done because the center of the curved surface and the axial center of the container 2 do not always coincide with each other due to the shaking of the curved surface.

Furthermore, the upper foreign matter determination unit 44, the middle foreign matter determination unit 45, and the lower foreign matter determination unit 46 respectively use the signals binarized with different sensitivities by the binarization circuits 39 to 41 from the inspection area setting unit.
The signals of each area 49 to 50 set by 47 are extracted respectively, and the extracted signals are compared with a predetermined reference value to detect whether or not foreign matter is contained in the filling liquid. It has become.

Although the container 2 is rotatably transferred by the rotating body 6 in the above-described embodiment, it goes without saying that the container may be transferred by a linear transfer means. Further, in the above-mentioned embodiment, the follow-up mirrors 31A and 31B are rotated reciprocally, but the present invention is not limited to this, and the follow-up operation of the container can be performed by the rotation operation in one direction.

[Advantages of the Invention] As described above, according to the present invention, by making a plurality of containers follow by a follow-up mirror, the photographing time for one container can be relatively lengthened, and the follow-up mirror follows an operation. When doing this, since at least the last container that was followed last time is included in the plurality of containers that are followed this time, it is possible to prevent the distance between the start position and the end position of the follow-up from increasing, and therefore the follow-up mirror It is possible to obtain an effect that the follow-up angle can be kept small to prevent the image from being distorted.
