Method for producing containers on a production line, with adaptation of the production rate in the event of an incident on the line

A method for operating a facility (1) for producing containers (2) from blanks (3) made of plastic material, the facility (1) comprising:

• several processing units, namely at least one unit (4) for thermally conditioning the blanks (3) and least one unit (5) for forming the containers (2) from the thermally conditioned blanks (3);
• at least one unit (8, 9) for transferring the formed containers (2) to a filling unit (6) or a labeling unit (7);
• a control unit (41) which controls at least the thermal conditioning unit (4), the forming unit (5) and the transfer unit (8, 9) by imposing on each of them a speed setpoint that is proportional to a rate of production of the containers (2);
• the method comprising:
• detecting an incident likely to affect the operation of the facility (1);
• determining reduction of the rate of production induced by the incident;
• applying the reduction to the speed setpoint of each processing or transfer unit (4, 5, 8, 9).
