A rotary filling machine includes a magnetic funnel attachment that can be easily installed, removed, and reinstalled into the machine for cleaning, changing the size of the funnel, inspecting, or replacing a damaged funnel. The magnetic funnel attachment includes a fill plate segment for receiving one or more funnels, and a funnel for attachment to the fill plate. The fill plate and funnel have mating alignment mechanisms to assist in the correct positioning of the funnel on the fill plate segment, and magnets to assist in the coupling of the funnel to the fill plate segment. This is especially helpful in creating a quick and easy method for funnel installation and removal.
