  When the pack product 100 moves on the guide plate 13 at the shooting position, the position of the bottom surface of the pack product 100 moves in a stable state, and stable shooting accuracy can be realized with the shooting conditions constant.

  The side imaging devices 31 and 32 and the bottom imaging device 33 take a frame by synchronizing with the conveying speed of the conveying device 1, and the control unit takes a predetermined gap L of the photographing hole 13 a of the guide plate 13 from the photographed image. An inspection image is formed by cutting out an area corresponding to, and connecting the cut-out images.

  As shown in FIG. 4, in the inspection image of the pit portion 103 captured by the side imaging devices 31 and 32, the background area BA of the packed product 100 appears as a bright area such as white, and the egg 102 is present in the pit section 103. The image area EA of the silhouette of the eggshell appears as a dark area such as black, the image area PA of the pit part 103 appears as a bright area such as white as the background area BA, and the leaked material 104 stays in the pit part 103. The image area LA of the leakage 104 appears as a dark area.

  For this reason, when the egg 102 stored in the pit part 103 is normal and the contents are not leaked, and the leaked substance 104 does not stay in the pit part 103, as shown in FIG. The lower end portion of the image area PA of 103 cannot be identified, and the lower end portion of the image area EA of the silhouette of the egg 102 reflected at a position away from the position corresponding to the lower end portion of the pit portion 103 can be clearly identified. it can.

  On the other hand, when the egg 102 stored in the pit portion 103 is abnormal and the leaked matter 104 leaked from the egg 102 stays in the pit portion 103, as shown in FIG. The silhouette image area LA of the leakage 104 can be identified together with the silhouette image area EA of the egg 102 stored in the container.

  In this case, when the amount of the leakage 104 as shown in FIG. 4A is large, or when the amount of the leakage 104 as shown in FIG. The silhouette image area EA and the silhouette image area LA of the leakage 104 are continuous, and the combined silhouette appears as a dark area reaching the bottom of the pit 103, and the lower end of the silhouette image area EA of the egg 102 The position of the lower end portion of the pit portion 103 can be identified.

  In addition, when the amount of the leakage 104 as shown in FIG. 4C is small, there is an image area EA of the silhouette of the egg 102 and an image area LA of the silhouette of the leakage 104 accumulated at the bottom of the pit portion 103. It appears as a discontinuous area, and the position of the lower end of the image area EA of the silhouette of the egg 102 and the lower end of the pit 103 can be identified.

  Therefore, as shown in FIG. 5, the presence or absence of the leakage 104 is determined by identifying the presence or absence of a silhouette reflected below the threshold with the position of the lower end of the egg shell silhouette of the egg 102 as the threshold in the examination image. As a result, the presence or absence of damage such as cracking of the egg 102 can be determined.

  Further, as shown in FIG. 4D, when the silhouette of the eggshell does not appear in the inspection image, the abnormal state can be determined that the egg 102 is not stored in the pit portion 103. Here, the shade shown in FIG. 4D is the silhouette of the eggs 102 arranged in the far side row.

  In the inspection image in which the bottom imaging device 33 captures the bottom surface of the packed product 100, as shown in FIG. 6, the background area BA of the packed product 100 appears as a dark region, and an image of the eggshell of the egg 102 that reflects the irradiation light. The area EA appears as a bright area, and the image area of the pit portion 103 through which the irradiation light passes appears as the same dark area as the background area BA.

  In this case, if the hole 105 is formed in the eggshell of the egg 102, the image area HA of the hole 105 appears as a dark area inside the image area EA of the egg 102 that appears as a bright area. The presence or absence of can be determined.

  Therefore, if there is a hole 105 in the eggshell of the egg 102 but the leakage 104 does not stay in the pit portion 103 because the contents have leaked from the eggshell before the eggs 102 are packed, the side shell In the inspection image of the pit portion 103 where the imaging devices 31 and 32 copy the packed product 100 from the side, it is erroneously determined that the egg 102 is normal, but the bottom imaging device 33 captures the bottom surface of the packed product 100. In the inspection image, it can be correctly determined that the egg 102 is abnormal, and a reliable determination can be made by using both inspection images.

  In addition, in the inspection image in which the bottom surface of the packed product 100 is copied, if the bright region of the egg 102 is not reflected at the position corresponding to the pit portion 103, it is assumed that the egg 102 is not stored in the pit portion 103 and that abnormal. The state can be determined.
