Abstract

Dispositif servant à immerger des pièces dans un réservoir de traitement contenant un liquide, tel qu'un bain de plaquage. D'après l'état actuel de la technique, on effectue le plaquage de pièces par transfert d'un réservoir à l'autre, hors du bain de traitement, après une durée déterminée d'immersion dans un dispositif comprenant une pluralité de réservoirs. Ce dispositif manque d'efficacité, étant donné qu'il est nécessaire de déplacer les pièces à la fois verticalement et horizontalement. Dans un dispositif d'immersion continue (10) du type transfert horizontal, tel que le décrit l'invention, des réservoirs de réserve (20, 22 et 24, 28) sont situées respectivement en avant et en arrière d'un réservoir de traitement contenant un liquide (18) et d'un réservoir de récupération et de neutralisation par rinçage à l'eau (26) et des portes (30 à 26) sont disposées entre lesdits réservoirs, de façon à pouvoir transférer la pièces du réservoir de réserve à l'extérieur, entre les réservoirs de réserve et du réservoir de réserve au réservoir de traitement (18) ou au réservoir de récupération (26) par déplacement horizontal uniquement, au moyen d'un dispositif de commande des portes et par l'intermédiaire d'un moyen de régulation de la quantité de liquide, afin d'améliorer l'efficacité du traitement.
