Abstract

L'invention concerne un dispositif de transfert qui comprend une roue à ailettes (FR) dont les ailettes (F) qui tournent autour de l'axe de la roue (RA) constituent des cellules (Z) qui reçoivent les objets arrivant sur un premier convoyeur (FE1) et qui les transfèrent sur les supports (ST) appropriés d'un second convoyeur (FE2). La répartition des ailettes montées mobiles dans la zone périphérique de la roue à ailettes (FR) peut être modifiée de manière à créer une ouverture large des cellules (Z) dans la zone d'entrée et une ouverture étroite desdites cellules (Z) dans la zone de dégagement. L'ouverture large des cellules (Z) créée dans la zone d'entrée garantit une réception fiable des objets (S), et l'ouverture étroite créée dans la zone de dégagement permet une correspondance avec le pas (t) des supports d'objets (ST) et par conséquent un transfert plus fiable des objets sur lesdits supports (ST).
