摘要:
A production control system provides real-time monitoring of process parameters in an automated production line that manufactures contact lenses, the line and having a plurality of process stations with each process station having one or more process control devices that control production operations at each respective process station and generates production parameter data therefrom. The system includes a line monitor device for receiving an externally generated production order including a lot number, product type, and quantity, and further coordinates manufacturing processes at each of the plurality of process stations, and tracks order production. A plurality of cell monitor devices retrieves the production data from one or more process control devices and processes the data to ensure that production parameters are within predefined limits. Real-time viewing of respective line status and device status information is provided by an interface device that accesses respective line status information from the line monitor device and production data from said cell monitor. Activation and completion of orders at each process station is also provided via the interface device.

摘要:
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. After inspection, the lenses and packages are transported to a water removal assembly, and then to another transfer assembly. This transfer assembly separates those lenses which passed inspection from those which did not, and places those that did in a consolidating assembly. The lenses and packages are then filled with saline solution and a foil label is then sealed thereto to form the primary package.

摘要:
The present invention, which relates to the transfer of contact lenses in post hydration processing of the lenses. A lens transfer and insertion assembly removes contact lenses from lens hydration pallets, alters their spatial distribution, and deposits them into packaging elements. The lenses are transferred with fluid and retained on the transfer assembly by surface tension.

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, which removes the lens-package elements from the pallet and deposits the optically correct ones onto a consolidating conveyor line; a consolidating conveyor line and rotating lens-package transfer assembly, the former consolidating the lenses into regular arrays, and the latter rotating and transporting them to the final station; and a saline solution injector and foil wrapper sealing assembly, which fills the packages with saline solution and then heat seals a foil wrapper to the tops of the packaging elements.

A contact lens production line pallet system transports contact lens mold materials throughout a facility for producing ophthalmic lenses. Specifically, the contact lens production line pallet system includes a pallet for carrying one or more contact lens mold assemblies throughout a contact lens production line, the pallet having one or more first recesses formed in a surface thereof for receiving either a first mold half or a complementary second mold half, the first and second mold halves when placed together constitute an individual contact lens mold assembly. A conveyor device for transporting the pallet from station to station throughout the production line facility is provided, as is a locating device formed in the pallet surface for enabling precise positioning of the pallet at one or more manufacturing stations in the production line facility.
摘要:
An automated method and apparatus is provided to mold, cure and package soft contact lenses. A conveyor system transports an array of molds through a plurality of automated work stations. The front curve mold halves are partially filled with a polymerizable monomer or monomer mixture and assembled and clamped to displace any excess hydrogel from the mold cavity. The assembly is precured and then transported through a cure station using UV radiation to complete polymerization, The assemblies are then pried apart in an automated station, with any excess monomer adhering to the removed mold half. The newly molded lens is then hydrated and separated from the front curve mold half in a hydration station. Following hydration the array of lens is automatically deposited into a plurality of packages with a robotic transfer device having a plurality of figures which transfer the lenses.
