Abstract

La présente invention concerne une machine de brossage de pattes pour le nettoyage/brossage de pattes de plaques tubulaires de batteries d'accumulateurs au plomb. La machine de brossage de pattes incorpore un transporteur d'alimentation (210), un transporteur principal (220) et une table rotative (230). La machine de brossage de pattes comprend en outre une première station de brossage (222) qui brosse des surfaces supérieure et inférieure de la patte, une deuxième station de brossage (224) qui brosse une surface d'épaisseur de la patte et des troisième et quatrième stations de brossage (234 et 236) qui brossent deux surfaces latérales de la patte. Les stations de brossage sont situées sur un transporteur principal à déplacement linéaire et une table rotative. Dans un autre mode de réalisation, la machine peut comprendre six stations permettant de mettre en œuvre des opérations requises le long d'un transporteur d'alimentation, d'un transporteur principal et d'un transporteur empileur, avec des stations de manipulation permettant d'empiler/de désempiler et de charger/décharger les plaques. La poussière générée pendant le processus de brossage au niveau du poste de brossage (200) est collectée par un système d'échappement et transportée vers une unité de collecte de poussière ou un système de collecte de poussière central où le plomb dans la poussière peut être extrait et recyclé.
