Riassunto
Durante il mio progetto di tesi sono stato inserito nella squadra di manutenzione di un impianto di paper converting con circa 300 dipendenti. Dopo una prima fase in cui mi sono dedicato alla comprensione del funzionamento dei macchinari e del software di gestione dello stabilimento, ho iniziato un processo di analisi dei guasti delle linee adibite alla produzione di prodotti arrotolati. Dall'analisi ho individuato una zona focalizzata che presentava delle criticità: le macchine per il confezionamento di una particolare linea di produzione. A quel punto ho applicato un metodo sistematico volto alla risoluzione di problemi cronici nell'ottica della Lean Manufacturing: il Focused Improvement. Dopo aver individuato le cause radice del problema ho ideato delle contromisure sia di tipo tecnico, con degli interventi di manutenzione proattiva, che legate ai metodi, pianificando delle manutenzioni preventive e formando degli operatori.
During my thesis project, I was assigned to the maintenance team of a paper converting plant employing approximately 300 people. In an initial phase, I focused on understanding the operation of the machinery and the plant management software, in order to gain a comprehensive overview of the production processes. Subsequently, I carried out a failure analysis of the production lines dedicated to rolled products.
This analysis made it possible to identify a specific critical area, consisting of the packaging machines of a particular production line. A systematic approach aimed at solving chronic problems, in accordance with Lean Manufacturing principles, was then applied to this area through the use of the Focused Improvement methodology.
After identifying the root causes of the issues, several countermeasures were defined and implemented. These included technical actions, such as proactive maintenance interventions, as well as methodological and organizational measures, including the planning of preventive maintenance activities and the training of line operators.
