Abstract

L'invention concerne un procédé et un dispositif d'évacuation automatique de bobines dans une machine formant lesdites bobines. Ledit dispositif comporte une unité de bobinage (4) de matériau en bande enroulé autour d'un mandrin (2a, 2b) disposé sur un axe porte-bobines (7, 12) supporté au niveau de ses extrémités dans ladite unité (4) par des éléments d'accouplement (8). Ledit axe (7, 12), qui supporte un mandrin (2b) muni d'une bobine complète (1), est remplacé par un axe porte-bobines (7, 12) muni d'un mandrin vide (2a). Ledit procédé consiste : à fixer ledit axe porte-bobines (7, 12) et un mandrin (2b) muni d'une bobine complète (1) par leurs extrémités dans l'unité (4), à détacher les éléments d'accouplement (8) et à retirer l'ensemble ; à libérer une des extrémités (7b, 12b) de l'axe porte-bobines (7, 12) de façon à le soutenir par son autre extrémité (7a, 12a) pendant qu'on remplace le mandrin (2b) muni d'une bobine complète (1) par un mandrin vide (2a) au moyen de mouvements axiaux d'introduction/extraction, en soutenant la bobine complète (1) pendant ces opérations ; et à fixer à nouveau l'extrémité (7b, 12b) de l'axe porte-bobines (7, 12) muni d'un mandrin vide (2a), à aligner l'axe muni d'un mandrin vide (2a) sur les éléments d'accouplement (8) de l'unité (4), à raccorder lesdits éléments d'accouplement (8) et à libérer l'axe lesdits éléments d'accouplement (8).
