Title: Ophthalmic lens containers
Inventor: EBEL JAMES A
IPC: B65D19/04
Filed: 1993-12-13
Abstract: An ophthalmic lens pallet is provided having wells for receiving one or more lens containers at the receiving point. The pallet achieves the requisite uniformity of motion needed in the direction of motion and stability when transporting the lens in the orthogonal, non-translating directions by restraining the pallet between rails. Mechanical bias means such as a spring-loaded roller ball located on the side walls of the pallet body cooperate with guide rails on the conveyor to compress the mechanical bias means when the pallet is between the guide rails. Engagement means on the pallet engage a drive means which transports the pallet from the lens receiving point to an inspection station then to a lens disposition mechanism. The pallet wells comprise holes that pass through the pallet. These holes along with the rail and transport system make possible an arrangement of a lamp and camera for capturing an image of a lens.
