Seal inspecting machine

A seal inspecting machine for inspecting bagged products to determine the presence or absence of a seal abnormality in each bagged product, which machine comprises:

• a presser unit for pressing the respective bagged product, said presser unit capable of being selectively moved in a direction close towards and away from the bagged product;
• and
• a servo motor capable of detecting a reactive force acting on the presser unit or capable of detecting a displacement of the presser unit, said presser unit being driven by the servo motor in the direction close towards and away from the bagged product,
• a control parameter storage means for storing control parameters that are used when the presser unit is moved by the servo motor, and a control means for realizing the control parameters from the storage means and operable to actuate the servo motor with the read-out control parameters;
• and
• a control specifying means for specifying the bagged products to be inspected and wherein the control parameter storage means stores the control parameters for each of the bagged products and the control means actuates the servo motor based on the control parameters corresponding to the bagged product specified by the specifying means.

• and
• a product characteristic detecting means for automatically detecting characteristics of each of the bagged products delivered before seal inspection, and a control parameter setting means for the control parameters based on the characteristics of each of the bagged product detected by the detecting means, and wherein the control parameter storage means stores the parameters that have been set by the control parameter setting means.
