MAQUINA AUTOMATICA PARA LA SELECCION DE FRUTOS REDONDOS,OVA-LES O PLANOS EN FUNCION DE SU DIAMETRO

摘要

The machine comprises a continuous conveyor having rollers which are parallel to each other and equally spaced apart and define gaps therebetween. In each of the gaps there is disposed another roller which is parallel to and equally spaced from said rollers. This other roller is movable upwardly or downwardly and cooperates with independent and adjustable guides. The fruit is sorted out by using at least the upper reach of the conveyor in which the various rollers rotate in the desired direction and at suitable speed and in which the movable rollers are moved by guide means progressively away from the fixed rollers as the rollers advance toward the end of the upper reach of the conveyor. The lower reach of the conveyor is either guided in such manner as to avoid rotating the movable rollers and fixed rollers or guided so that the movable rollers are again progressively moved away from the fixed rollers as the latter and the movable rollers are rotated. The latter arrangement doubles the output of the machine.
