Abstract

Viene presentato un procedimento completamente automatico per suddividere pelle naturale, in cui per mezzo di una camera i difetti strutturali e del materiale nonché i contorni esterni della pelle vengono rilevati e i punti difettosi, caratterizzati da differenti tonalità cromatiche, vengono forniti all'unità di comando elettronica. Nell'unità di comando elettronica sono memorizzati contorni di modelli da tagliare, laddove ad ogni contorno sono associate determinate zone con gradi di difetto ancora tollerabili. Ad ogni grado di difetto corrisponde una definita tonalità cromatica, cosicché difetti dello stesso grado sono caratterizzati dallo stesso colore (nel caso di camere in bianco e nero: gli stessi valori grigio; nel caso di camere a colori: la stessa temperatura). Tramite un programma software ha quindi luogo una operazione automatica di suddivisione, ossia i contorni dei modelli memorizzati nel sistema di comando elettronico vengono riuniti elettronicamente tenendo conto di preassegnati condizionamenti e vengono così simulati differenti complessi di ritagli. Quando si è trovato un complesso di ritaglio ottimale, ossia si è realizzato il massimo grado di sfruttamento possibile, questo complesso di simulazione viene memorizzato e successivamente utilizzato per comandare l'impianto di taglio automatico.(Figura 1).
