Patent number: 6253817Abstract: 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.Type: GrantFiled: February 5, 1998Date of Patent: July 3, 2001Assignee: Johnson & Johnson Vision Care, Inc.Inventors: Russell James Edwards, Masao Funo, Richard Wayne Abrams, Kiyoshi Imai, Hirokazu Kitagawa, Borge Peter Gundersen, William Edward Holley, Thomas Christian Ravn, Mark Edward Schlagel, Daniel Tsu-Fang Wang

Patent number: 5749205Abstract: An automated apparatus for controlling the automatic packaging of contact lenses in a contact lens fabrication facility includes: a first robotic transfer device for periodically transferring a first predetermined amount of individual packages from an inspection station to an intermediate consolidation buffer and depositing the packages on the consolidation buffer; a control device for tracking and identifying each individual contact lens conveyed from the inspection station to the consolidation buffer and including memory and logic circuits for staring the identity of individual packages containing contact lenses that have been previously determined at the inspection station as being out of specification, and, generating a signal to enable the first robotic device to discard any individual package identified as out of specification; and, a second robotic assembly for periodically transferring a second predetermined amount of individual packages from the consolidation buffer to a second processing station, thType: GrantFiled: June 5, 1995Date of Patent: May 12, 1998Assignee: Johnson & Johnson Vision Products, Inc.Inventors: Russell James Edwards, Mary Louis Dolan, Svend Christensen, Borge Peter Gundersen, John Mark Lepper, Daniel Tsu-Fang Wang, Richard Wayne Abrams, Thomas Christian Ravn

Patent number: 5745230Abstract: A lens inspection method and apparatus comprising a pallet having wells for receiving one or more lens containers at the receiving point. A conveyor achieves uniformity of pallet motion when transporting the lens. The pallet wells includes holes that pass through the pallet. These holes, along with a side driven transport system, make possible an arrangement of a lamp and camera on opposite sides of the lens for capturing an image of a lens. A computer implemented algorithm processes the digitized image to determine the acceptability of the lenses. A lens disposition mechanism uses a signal generated by the computer and indicates lens acceptability to disposition the lens by physically separating a container with an acceptable lens from an unacceptable lens. After disposition of containers, the pallet is returned by conveyor to the lens receiving point.Type: GrantFiled: July 29, 1996Date of Patent: April 28, 1998Assignee: Johnson & Johnson Vision Products, Inc.Inventors: Russell J. Edwards, James A. Ebel, Borge Peter Gundersen, Thomas Christian Ravn

Patent number: 5706634Abstract: 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.Type: GrantFiled: May 1, 1995Date of Patent: January 13, 1998Assignee: Johnson & Johnson Vision Products, Inc.Inventors: Russell James Edwards, Darren Scott Keene, William Edward Holley, John Mark Lepper, Wallace Anthony Martin, Daniel Tsu-Fang Wang, Ture Kindt-Larsen, Niels Jorgen Madsen, Borge Peter Gundersen, Thomas Christian Ravn

Patent number: 5687541Abstract: 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.Type: GrantFiled: June 5, 1995Date of Patent: November 18, 1997Assignee: Johnson & Johnson Vision Products, Inc.Inventors: Wallace Anthony Martin, Russell James Edwards, Borge Peter Gundersen, Darren Scott Keene, Ture Kindt-Larsen, John Mark Lepper, Niels J.o slashed.rgen Madsen, Thomas Christian Ravn, Daniel Tsu-Fang Wang, William Edward Holley
