Automatic package inspecting system

A package inspecting system, which comprises:

• a packaging machine including a vertical sealing device for sealing opposite longitudinal side edges of a packaging material, which extend in a direction conforming to a direction of flow of the packaging material, together to render the packaging material into a tubular form, and an end sealing device for sealing an end of the tubular packaging material after articles have been filled in the tubular packaging material, to thereby provide a bagged product;
• a weight checker for weighing the bagged product;
• a sealer checker for inspecting a sealing condition of the packaging material of the bagged product;
• a determining means for diagnosing an abnormal condition or a content of abnormality occurring in each of the sealing devices according to a combination, of both, of respective results of detection performed by the seal checker and the weight checker with respect to the same bagged product;
• and
• an indicating means operable to indicate a result of the diagnosis.

A package inspecting system comprising:

• a packaging machine including a longitudinal seal former operable to seal opposite longitudinal edges of a packaging material together to render the packaging material into a tubular form, and an end seal former operable to seal an end of the tubular packaging material after articles have been filled in the tubular packaging material, to thereby provide a bagged product inside a formed bag;
• a seal checker operable to check the integrity of a seal on the packaging material of the bagged product;
• a bite detector operable to determine whether bagged articles have been caught in the sealed end of the packaging material;
• and
• a controller operable to diagnose an abnormal condition based on a combination, of both, of signals from the seal checker and the bite detector with respect to a single formed bag.
