  • Patent number: 6708397
    Abstract: In a soft contact lens manufacturing process, an injection molding machine (IMM) produces many thermoplastic injection molded front curve (FC) and back curve (BC) mold parts, each of which mold parts is subsequently used only once to mold a single soft contact lens. An inlay station with alignment assemblies and transfer tubes provide for the precise transfer to and alignment of the FC and BC molds in pallets during their transfer from the IMM to pallets on an assembly line in a high speed automated commercial production operation. A rotatable FC transfer arm and a rotatable BC transfer arm transfer the FC and BC molds from the IMM machine to the pallets in an inlay station. The precisely aligned transfer is provided by two alignment rods of an alignment assembly which pass through two alignment apertures in the pallet and then pass through two alignment apertures in one of the FC or BC alignment arms.

  • Patent number: 5540543
    Abstract: Apparatus for removing and transporting ophthalmic lens mold sections from a mold, and generally comprising first, second, and third assemblies. The first assembly removes the lens mold sections from the mold and transports the lens mold sections to a first location, the second assembly receives the lens mold sections from the first assembly and transports the lens mold sections to a second location, and the third assembly receives the lens mold sections from the second assembly and transports the lens mold sections to a third location. Preferably, the first assembly includes a hand to receive the lens mold sections from the mold and to releasably hold the lens mold sections, and a support subassembly connected to the hand to support the hand and to move the hand between the mold and the first location.
