Production line of absorbent sanitary articles

A production line of absorbent sanitary articles, comprising:

• production devices configured to perform respective production operations on the absorbent sanitary articles being processed along the production line;
• sensors adapted to detect current values of operating parameters which are indicative of the current operation of at least one of the production devices;
• a control unit comprising a memory and a processor configured to perform a comparison between the current values of the operating parameters detected by the sensors and respective predetermined reference values stored in said memory and, in a presence, among said operating parameters, of at least one anomalous operating parameter whose current value does not comply with the respective predetermined reference value, to identify, among a plurality of possible malfunctioning causes of the line, at least one current malfunctioning cause responsible for said at least one anomalous operating parameter;
• wherein the processor is configured to perform said comparison independently of a detection of any defects performed on the absorbent sanitary articles;
• and
• wherein the processor is configured to identify said at least one current malfunctioning cause starting from said at least one anomalous operating parameter by means of decision algorithms which are based on at least one of the following information stored in said memory:
• known and/or self-learned data related to correlations between said at least one anomalous operating parameter and said plurality of possible malfunctioning causes of the line;
• current and/or historical information manually provided by an operator in association with said at least one anomalous operating parameter and/or said possible malfunctioning causes of the line;
• known and/or self-learned logic rules.
