  • Apparatus and method for handling particulate material
    Publication number: 20080135129
    Abstract: Particulate material, such as toner, is stored within a hopper (12) which leads to a feed screw (30). The feed screw (30) moves the particulate material through an outlet passageway (24) into a discharge spout (26). The outlet (46) of the discharge spout (26) delivers the toner into the inlet of a funnel (52). The funnel (52) delivers the toner into the inlet (50) of a toner cartridge (48). The toner cartridge (48) and funnel (52) are mounted by a carriage (56) for back and forth movement below the outlet (46). The rate of toner feed is coordinated with the cartridge travel so that the toner is substantially evenly distributed into the cartridge (48).
