Abstract
The present invention, which relates to post hydration processing of contact lenses and the packages into which the lenses are placed, includes several assemblies which are ideally suited to performing the various steps which are associated with post hydration processing. These several assemblies include: a deionizing water injection assembly which fills the packaging elements prior to the lenses being inserted therein; a lens transfer and insertion assembly which removes contact lenses from hydration pallets, alters their spatial distribution, and deposits them into the packaging elements; a buffering station, which includes segregator and integrator devices, and which provides a location for temporarily holding a group of lens-packaging pallets during interruption of subsequent assemblies; a low vibration lens-package transport and inspection assembly which removes the pallets from a conveyor line, inserts them onto low vibration inspection assembly conveyor line, and inspects the lenses to determine which are optically correct; a deionized water extraction assembly which removes the deionized water from the lens-packaging elements; a first rotating lens-package transfer assembly…
