ABSTRACT:
An apparatus (10) for handling parts (a,a') by magnetic attraction includes a cylindrical casing (18) of nonmagnetic material having an uninterrupted surface throughout its length and a magnet (20) for magnetically attracting parts (a,a') to the casing (18). Nonmagnetic ramps are spirally wound around the casing (18). A drive mechanism (26) rotates the magnet (20) relative to the ramp. The magnet (20) attracts the parts to the casing (18) and causes the parts (a,a') to rotate about the axis of the casing (18) while the ramps (30) cause the parts (a,a') to advance along the length of the casing (18). The ramps (30) include a multiple part segregating mechanism for segregating parts received and discharged along the length of the casing (18).
