When inspecting the appearance of the
Since it is necessary to inspect b and 1c, the extruded product 1 must be observed from above and from both sides.
Conventionally, when performing such an appearance inspection from multiple directions, a plurality of cameras are installed so that images of each surface of the inspection object can be captured, the camera itself is moved, or the inspection object is moved. Or, a method of rotating is used. Alternatively, as described in JP-A-6-273339, there is a method in which an image of each surface of the inspection object held at a fixed position is imaged from one direction by using a plurality of reflecting mirrors.

The light is received by the one-dimensional CCD camera 15 via 3 and 14. At this time, the extruded product 1 is moving in the direction of arrow A, and the light receiving amount of each constituent pixel of the one-dimensional CCD camera 15 is sequentially detected in the direction of arrow B, and the extruded product 1 is scanned in the same direction. Therefore, the bottom surface 1 a and the side surface 1
b and 1c are continuously imaged on the entire surface. Thus, it is possible to inspect continuously manufactured extruded products 1 on a production line while reducing costs by performing imaging from one direction using a one-dimensional CCD camera 15, thereby improving inspection efficiency. As a result, production efficiency can be improved.

できる。The amount of light received by the one-dimensional CCD camera 15 is
When the surface of the extruded product 1 is uniform, it is not less than a certain value and hardly changes depending on the imaging location. On the other hand, when the surface of the extruded product 1 has a convex portion 1d (see FIG. 4), when light is irradiated from the oblique direction to the surface, the vicinity of the convex portion 1d becomes dark, and the one-dimensional CCD camera 15 has a characteristic that the amount of received light decreases. For this reason, by setting an appropriate binarization threshold value in advance, when the convex portion 1d is scanned, the amount of light received by the one-dimensional CCD camera 15 is reduced as shown in FIG. , The abnormal appearance of the extruded product 1 can be detected. Further, the width of the foreign matter (the width of the convex portion 1d) can be detected based on the width w of the portion below the binarization threshold value. stored in advance in the width w o corresponding to 0.5mm as quality determination reference value, poor appearance unit the imaging position in the case of the former the detected width w as compared to the width w o exceeds the latter It is judged as. Thereby, the appearance inspection device 7 can detect even a minute defect with high accuracy.
