Method to set up a movable operating member of an automatic machine for manufacturing or packaging consumer articles

A method to set up at least one movable operating member (5, 7, 7′) of an automatic machine (1) for manufacturing consumer articles (3), the method comprising the steps of:

• defining a first motion profile (FP) of the at least one movable operating member (5, 7, 7′), through which at least one processing of the articles (3) is to be carried out;
• correlating the first motion profile (FP) of the at least one movable operating member (5, 7, 7′) with at least one conversion parameter (50) concerning the articles (3) to be manufactured;
• defining a corresponding second motion profile (SP) of an electric actuator system (8, 9), which, through a motion transmission system (12), is mechanically connected to the at least one movable operating member (5, 7, 7′) and moves the at least one movable operating member (5, 7, 7′) with the first motion profile (FP);
• detecting possible imperfections in the at least one processing of the articles (3) by the at least one movable operating member (5, 7, 7′);
• correcting, by means of an interface device (15) of the automatic machine (1) and based on said detected possible imperfections, the at least one conversion parameter (50) concerning the articles (3);
• processing, by means of a control unit (14) and depending on the correction of the at least one conversion parameter (50), the first motion profile (FP), thus obtaining a first modified profile (MFP) of the at least one movable operating member (5, 7, 7′);
• calculating, by means of the control unit (14), a reverse kinematics of the first modified profile (MFP) of the at least one movable operating member (5, 7, 7′) through the motion transmission system (12) so as to obtain a corresponding second modified profile (MSP) to be commanded to the electric actuator system (8, 9);
• and
• modifying control of the electric actuator system (8, 9) so as to carry out the corresponding second modified profile (MSP).
