Abstract
Deve essere indicata un'apparecchiatura (10) per la classificazione di difetti (14) in pelli (12), che consenta la cernita automatica, ad uno stadio di concia del cuoio il più possibile, di determinati livelli qualitativi in funzione dei difetti, onde evitare fasi di concia costose per qualità inferiori, senza dipendere per tale decisione da controlli visivi soggettivi difficilmente riproducibili. A tale scopo la pelle (12), già spaccata, sottoposta ad una prima concia e ben distesa, viene trascinata, con avanzamento predefinito, attraverso un'apparecchiatura (23) di irradiazione, ove viene irradiata con una lama di luce infrarossa ad onde lunghe sul lato della grana, ovvero attraversata dalla luce sul lato carne, in modo da registrare righe successive trasversali alla direzione (18) di avanzamento della proiezione d'ombra dipendente dai difetti, ovvero dell'attenuazione della luce passante dipendente dai difetti e dalla struttura, mediante funzionamento stroboscopico elettrico o meccanico. Una realizzazione economica utilizza lampade al quarzo a radiazione termica, e telecamere CCD di consumo, queste ultime previa asportazione del filtro per infrarosso normalmente incorporato, comunemente reperibili in commercio. Mediante un sistema esperto, addestrato per riconosce i vari difetti tipici ed integrato in una rete neuronale, i difetti (14), rappresentati da oscillazioni di intensità, vengono convertiti, in un'apparecchiatura (30) di valutazione, tenendo conto della loro grandezza, posizione e numero, in informazioni (33) di classificazione, che, mediante un apparecchio (32) marcatore, vengono marcate sulla pelle (12) e possono servire per il comando di un impianto (34) di cerniera, per un ordinamento classificato della pelle (12).(Figura 3).
