摘要:
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. The second assembly preferably includes a support frame, a platform to receive the lens mold sections from the first assembly and supported by the support frame for movement between the first and second locations, and moving apparatus for moving the platform along the support frame and between these first and second locations. The preferred design of the third assembly includes a transport subassembly and a support column. The transport subassembly receives the lens mold sections from the second assembly, releasably holds those lens mold sections, and carries the lens mold sections to the third location; and the support column supports the transport subassembly for movement between the second and third locations.
摘要:
A computer control system for optimizing process parameters in an automated production line for producing contact lenses. The system comprises a plurality of process controllers for controlling one or more process stations of the production line, each of the controllers regulating a plurality of process control devices that each control specific production parameters used in the automated manufacture of contact lenses at the process station(s). An automated lens inspection device automatically evaluates each contact lens produced and generates inspection data for each contact lens, and a polling device polls each of the process controllers on a frequent basis to acquire process control data for each period. Further included is a correlating device for correlating the inspection data to the process control data and the contact lens data to optimize process parameters used in the production of contact lenses. A relational database is also provided for storing the process control data, the contact lens data and the inspection data received from the correlating device.
摘要:
An interactive control system for controlling the automatic packaging of contact lenses in a contact lens fabrication facility, the interactive control system consisting of a first robot device for periodically transferring individual arrays of a first predetermined amount of discrete contact lens packages each containing a contact lens therein from a first station to an intermediate conveyor where the individual arrays are conveyed to a second station, and a controller for initiating a time stamp for each individual array transferred from the first station and determining elapsed time data for each individual array and for generating position status data indicating a good array or a bad array of defective lenses for each individual array as it is conveyed to the second station, the controller shifting the elapsed time data and position status data for each individual array as it is conveyed on the intermediate conveyor for transfer to the second station.
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:
An apparatus for the processing and segmenting of a cover-forming laminate web or sheeting structure which is adapted to interconnect a plurality of containers, such as the base members of blister packages each of which is designed to contain a hydrophilic contact lens in a sterile aqueous solution. More specifically disclosed is an apparatus for the imprinting, perforating, slitting and cutting the laminated web structure such that the severed laminate segments constitute printed covering label for an array of such containers, and whereby the laminated web or sheeting segment may be severed along weakening or perforation lines so as to provide a separable packaging arrangement for individual of the containers which are subsequently adhered thereto.
摘要:
A device and method for high speed production rates in the hydration of soft contact lenses. Such device and method includes the use robotic transfer equipment to transfer contact lens molds containing contact lenses to and from a hydration station and a flushing station.
摘要:
The present invention provides apparatus for dispensing ophthalmic lens packages. A plurality of ophthalmic lens packages are loaded into the apparatus and the apparatus determines an identity of each ophthalmic lens package. A housing stores the ophthalmic lens packages and records a location and identity of each of the lens packages and dispenses a particular ophthalmic lens package.
