Production line for absorbent sanitary articles

A production line for absorbent sanitary articles comprising a working area configured to carry out respective production operations on the absorbent sanitary articles being processed along the production line and an automated control and monitoring system for the production line, the control and monitoring system comprising control devices operatively associated with the working area and a central control unit operatively connected to the control devices, the control unit comprising a processor which is configured, in relation to a determined time period of operation of the production line, to:

• obtain discard event data indicative of discard events that led to discarding absorbent sanitary articles during the determined time period and, for each discard event, specific discard data indicative of a number of absorbent sanitary articles discarded in association with the discard event;
• obtain stop event data indicative of stop events that led to stop the production line during the determined time period and, for each stop event, specific stop data indicative of a stop time of the production line associated with the stop event;
• process the discard event data and the specific discard data obtained in order to classify the discard events according to their incidence on a total number of absorbent sanitary articles discarded during said determined time period and select a limited number of discard events that had a greatest impact on the total number of discarded absorbent sanitary articles;
• process the stop event data and the specific stop data obtained in order to classify the stop events according to their incidence on a total stop time of the production line during said determined time period and select a limited number of stop events that had a greatest impact on the total stop time of the production line;
• identify discard root causes for the selected limited number of discard events;
• identify stop root causes for the selected limited number of stop events;
• define an action to be implemented with reference to at least one of the identified stop root causes and the identified discard root causes.
