Closure lining and color detector
First Claim
1. A system for identifying a predetermined color of decorated metal disks that are capable of being formed into container closures, said system comprising:
- a conveyor for moving said plural decorated metal disks longitudinally therealong, said decorated metal disks having a colored side that is oriented upwardly on said conveyor; and
a color sensor that senses said colored side of each one of said decorated metal disks for predetermined color, said color sensor being capable of identifying a sufficient color status that corresponds to a predetermined color on at least a portion of said decorated metal disk and a deficient color status that corresponds to a color that is not said predetermined color, wherein said color sensor senses a predetermined wavelength of light to identify the sufficient color status;
a separator capable of removing from said conveyor a decorated metal disk having a deficient color status;
whereby said system automatically identifies and removes said decorated metal disks that have said deficient color status from the conveyor.

Abstract
A system is disclosed for detecting or inspecting for a lining of a container closure that is formed of a sheet metal and has a panel on an inside surface of the closure. The panel of the closure has a lining formed thereon. The system according to the present invention includes a conveyor for moving plural closures longitudinally and substantially through the system, a color sensor that inspects the panel of each one of the closures on the conveyor for a predetermined color, and a separator that is capable of removing closures that lack the predetermined color. The system may include an oven downstream from the sensor to bake the lining. Thus, the system automatically identifies and removes the closure having the deficient color from the conveyor. A corresponding method for identifying and removing a closure having a deficient color is also disclosed.

4. A method for identifying a predetermined color of decorated metal disks that are capable of being formed into container closures, said method comprising the steps of:
-
(a) conveying the decorated metal disks to a color sensor on a conveyor longitudinally therealong;
(b) sensing a color on an upwardly oriented colored side of each one of the decorated metal disks by said color sensor;
(c) identifying the color as either a sufficient color or a deficient color, the sufficient color corresponding to a predetermined color, the deficient color corresponding to color that is not the predetermined color, and comparing the color of each one of the decorated metal disks to the predetermined color to determine whether the color is the sufficient color, wherein comparing the color of each one of the decorated metal disks to the predetermined color includes comparing a wavelength of the color to a predetermined range of wavelengths;
(d) separating the decorated metal disks having a deficient color status from the disks having a sufficient color status. - View Dependent Claims (5, 6, 8, 9)
