Abstract

A beltless magnetic conveyor assembly including a housing defining a longitudinal length of the conveyor and a magnetic rack assembly moveably supported in the housing. The magnetic rack assembly includes a plurality of magnet assemblies supported at spaced intervals relative to one another along the longitudinal length of the conveyor. The beltless magnetic conveyor assembly also includes a drive system which is operable to index the magnetic rack assembly between a home position proximate to one end of the housing and an end position which is proximate to an opposite end of the housing over the same path. The magnet assemblies are operable to generate a magnetic force which acts to attract ferromagnetic material toward the housing and to move the ferromagnetic material in the direction of the longitudinal length of the conveyor when the magnet rack assembly is indexed in one direction. However, the magnet assemblies are also operable to change the force such that ferromagnetic materials are not moved in the direction of the longitudinal length of the conveyor when the magnet rack assembly is indexed in the opposite direction over the same path.
