Publication number: 20160379380Abstract: A system and method for gaging the shape of a curved panel includes, as components, (1) a system and method for acquiring three-dimensional surface data corresponding to the panel, and (2) a system and method for receiving the acquired surface data, comparing the acquired surface to a pre-defined surface description, and developing indicia of the level of conformance of the contoured panel to the pre-defined specification. The surface data acquisition system includes a conveyor for conveying the panel, at least one display projecting a preselected contrasting pattern, and at least one camera. The camera(s) and display(s) are uniquely paired and are mounted in a spaced-apart relationship a known distance and angle from the surface of the panel such that the camera detects the reflected image of the pattern projected on the surface of the panel from its associated display.Type: ApplicationFiled: June 26, 2015Publication date: December 29, 2016Inventors: Jason C. ADDINGTON, Michael J. VILD, Benjamin L. MORAN

Publication number: 20150308943Abstract: A glass sheet acquisition and positioning mechanism and associated method are utilized in an in-line glass sheet optical inspection system. The mechanism includes an exterior support frame mounted in proximity to one of the glass sheet processing system conveyors, and an interior support frame operably connected to the exterior support frame such that the interior support frame may be selectively positioned from its first orientation to a second orientation whereby the retained glass sheet is positioned between the camera and the screen at a preselected position. The interior support frame is also operably connected to the exterior support frame to provide for positioning of the interior support frame to a third orientation in which the glass sheet is released from the interior support frame for continued movement on the conveyor. An in-line glass sheet optical inspection system incorporating the glass sheet acquisition and positioning mechanism is also disclosed.Type: ApplicationFiled: April 29, 2014Publication date: October 29, 2015Applicant: GLASSTECH, INC.Inventors: Michael J.

Patent number: 8132428Abstract: A method for forming glass sheets is performed by a system (10) that includes a forming station (14) having lower and upper molds (28, 30) between which glass sheets G are cyclically received from a furnace (12) on a vacuum transfer platen (34), formed between the lower and upper molds (28, 30), and transferred to a delivery mold (42) for delivery such as to a quench station (16). The vacuum transfer platen (34) and the delivery mold (42) are moved at different elevations into the forming station (14) in respective underlapping and overlapping relationships to each other so each glass sheet forming cycle can begin within the forming station before the prior forming cycle is completed in a time overlapping manner that reduces the cycle time.Type: GrantFiled: August 25, 2008Date of Patent: March 13, 2012Assignee: Glasstech, Inc.Inventors: Michael J. Vild, David B. Nitschke, Dean M. Nitschke, James P. Schnabel, Jr.

Patent number: 8049879Abstract: An apparatus and associated method for measuring transmitted optical distortion in a glass sheet includes a glass stand which receives a glass sheet for mounting between a background screen which includes a matrix of spaced apart dots, and a digital camera which captures (1) an image of the glass sheet surface, and (2) an image of the dot matrix transmitted through the glass sheet. The captured images are downloaded to a computer that is suitably programmed to analyze the image data to (1) determine the presence of any markings or elements on the surface of the glass sheet that should be isolated from the dot matrix image, (2) modify the background image to eliminate the image data corresponding to any such surface markings or elements from the image, and (3) determine characteristics indicative of optical distortion in the modified image of the dot matrix background transmitted through the glass sheet.Type: GrantFiled: April 14, 2009Date of Patent: November 1, 2011Assignee: Glasstech, Inc.Inventors: Donivan M.

Patent number: 5948132Abstract: A glass sheet strip annealing method utilizes a housing (18) along which a conveyor (26) including a gas support (28) supports a glass sheet strip G by pressurized gas for movement between entry and exit ends (22,24) of the housing before a conveyor drive (32) engages the strip after the surfaces thereof are cooled below the strain point. Best results are achieved when the glass sheet strip is supported only by the gas support (28) until its surfaces are placed in compression. Lower and upper manifolds (34,36) respectively support and convey the glass sheet strip within the housing (18) preferably by a recirculating gas flow supplied by gas burner (76) and associated gas jet pumps (78).Type: GrantFiled: October 8, 1997Date of Patent: September 7, 1999Assignee: Glasstech, Inc.Inventors: Robert E.
