PROBLEM TO BE SOLVED: To provide an inspection method of a packing bag which can exactly determine whether or not an extraction bag accommodated in the packing bag bites into a seal area, and an inspection device.SOLUTION: After photographing a packing bag 8 which is transported by a first transport conveyor 2 by a first photographing device 20, an impact is imparted to a second transport conveyor 10 which is arranged having a difference in a height with the first transport conveyor 2 by making the packing bag 8 fall on the second transport conveyor 10. After that, the packing bag 8 is photographed second time by a second photographing device 38 which is arranged at the second transport conveyor 10. Images which are photographed by the photographing devices 20, 38 in two points are sent to an appropriateness determination part 36 after being processed by an image processing part 34. By comparing the two images, when corners of an extraction bag which is accommodated in the packing bag 8 are not moved in the vicinity of a boundary of a seal area, it is determined that the extraction bag bites into a seal part, and when the corners are moved, it is determined that the extraction bag does not bite into the seal part.SELECTED DRAWING: Figure 1 |
