Patent number: 5432545Abstract: A method is provided for detecting the color of objects such as bottles to be recycled so as to enable the bottles to be separated by color. The method which is particularly concerned with determining the color of an object (bottle) with a label attached thereto, begins with the storing of a reference image. Next, a determination is made of whether a bottle is present or absent. If a bottle is present, the image of the bottle is then separated into an intensity image representation of the bottle image, a saturation image representation of the bottle image, and a hue image representation of the bottle image. Then, the reference image is subtracted from the intensity image so that a resultant image is produced with the background contribution removed. Next, a logical "AND" operation is performed on the resultant image and the hue image to create a further image which has no background components. A histogram is then performed on the further image to determine the hue with the maximum number of occurrences.Type: GrantFiled: December 6, 1993Date of Patent: July 11, 1995Inventor: Joseph W.

Patent number: 4691231Abstract: A method and apparatus for inspecting the sidewalls of containers on a continuously-moving conveyor includes recording instantaneous upper and lower angularly-spaced images of the bottles as they pass. Data on the images is stored as numeric data indicating the grey shade of each pixel in a matrix of pixels, which matrix is examined for edges and then divided based on detected edges into inspection windows. The windows are subject to separate criteria between typically scuffed areas and open areas. The occurrence of pixels in at least three grey ranges reflecting clear glass, opaque glass, and scuffed glass, together with the correlation of such occurrences between angularly-spaced views and upper and lower views, is processed to detect defects. A memory stores a status indication in a queue representing the acceptability of the bottles being examined, which are then segregated by a downstream reject kicker mechanism.Type: GrantFiled: October 1, 1985Date of Patent: September 1, 1987Assignee: Vistech CorporationInventors: Tyce Fitzmorris, Eric Espenhahn, Jamie Pereira

Patent number: 4278173Abstract: There is described a plug and air warp gauge which takes the form of an elongated vertically, reciprocated gauging head that is mechanically driven under the influence of a rotating cam. Coaxially within an annular head is positioned a plug which has a diameter such that it will pass through an unchoked neck of a bottle. The plug is attached to the lower end of a tube which is coaxially positioned within a larger tube. The larger tube is raised and lowered mechanically and when in its uppermost position, will support the plug-carrying tube. When the larger tube is lowered, the plug tube also is lowered. The lower end of the larger tube is in the form of an annular piston which will move downward within a cylinder that seats on the bottle finish. As the annular piston moves down, it will pressurize the inside of the bottle and the cylinder if the seal with the finish of the bottle is good.Type: GrantFiled: September 10, 1979Date of Patent: July 14, 1981Assignee: Owens-Illinois, Inc.Inventors: Ernest H.
