  • Automated apparatus for preparing contact lenses for inspection and packaging
    Patent number: 5578331
    Abstract: An apparatus is provided for removing and transporting articles, such as contact lens sections from a manufacturing line to inspection and packaging stations. The lenses are deposited in a transparent plastic primary package which carries the lenses through the inspection station and becomes part of the primary package when a cover is sealed thereto. The invention includes various assemblies, including lens transfer assemblies, deionized water filling and removal assemblies, a water degassing assembly, a lens inspection assembly, and a lens package sealing assembly. The lenses are removed from pallets at a post hydration station, transported and spatially redistributed, and deposited in the primary packages disposed on a second set of pallets. The packages on the second set of pallets are filled with degassed deionized water. The contact lenses and packages are then transported to an inspection station.
