METHOD FOR THE PREDICTIVE MAINTENANCE OF AN AUTOMATIC MACHINE FOR MANUFACTURING OR PACKING CONSUMER ARTICLES

A method for the predictive maintenance of an automatic machine for manufacturing or packing consumer articles comprising the steps of: detecting and recording at least a sampling series relating to at least one motorization metric of at least one electric actuator, by means of at least one respective local control unit; transmitting the recorded sampling series to a data processing unit; defining at least one multidimensional tolerance horizon within an anomaly matrix having as dimensions at least two statistical features based on at least one sampling series detected and relative at least to the detected motorization metric; calculating the two statistical features in order to define the position of an actual condition within the anomaly matrix; determining, based on the position of the actual condition in the anomaly matrix and the multidimensional tolerance horizon, the imminence of necessary maintenance.
