Carrier bead pickoff device

机译:载珠提取装置

摘要

A carrier bead pickoff device is provided for removing ferromagnetic carrier beads from a developed image-carrying surface of a moving photoreceptor in an electrostatographic image reproduction machine. The carrier bead pickoff device includes (a) an elongate stationary core having a first elongate segment, and a second elongate segment, the second elongate segment including a primary magnetic member for generating a concentrated magnetic field within a pickoff region locatable proximate the developed image-carrying surface; (b) a rotatable, non-ferromagnetic cylindrical shell mounted co-axially over the elongate stationary core and having a first end, a second end, and a shell wall having a smooth outer surface; and (c) at least one elongate ferromagnetic strip formed over a portion of the smooth outer surface (i) for rotation with the portion, (ii) for temporary magnetization when rotating through the concentrated magnetic field within the pickoff region, and (iii) for contacting and retaining ferromagnetic carrier beads, attracted by the primary magnetic member towards the smooth outer surface, during rotation of the portion of the smooth outer surface through the pickoff region.
