ABSTRACT:
A method for inspecting bags having folded and pasting bottoms. Light source is provided to irradiate a bottom of a moving bag with a light so that shadows appear along a shape of bottom folds. A CCD linear array image sensor takes an image of the bottom of the bag from the reflected light and delivers electric signal corresponding to the image. The electrical signal are processed to extract a shape of bottom folds based on the shadows on the irradiated bottom. The obtained outer profile is compared with a reference input of a good bag stored in a memory to emit an electric selection signal classifying whether it is a good product or a defective product.
