摘要： A gin process control system including sensing stations for sensing the physical properties of cotton as it progresses through a gin. A moisture sensor determines, over a wide range of values, the amount of moisture in the cotton. A quality monitor determines the color of the cotton, color distribution, and the amount and type of trash or other impurities which may be entrained in the cotton. A micronaire unit determines both micronaire and cotton maturity. A fiber length tester provides information on the length distribution, breaking strength, and elongation of the cotton fibers. Cotton samples are gathered from the gin flow stream and presented to the sensing stations in a variety of manual, semi-automated, and automated fashions. In a fully automated unit, the sensing stations are connected directly to the gin. The sensing stations are also in communication with the gin process control system, which uses the data from the sensing stations to automatically control the operation of the gin. Alternately, the sensing stations are assembled into a stand-alone unit. In a semi-automatic version of the stand-alone unit, samples are manually gathered and presented to the unit in cassettes for automated subsampling and testing by the sensing stations. In this semi-automatic version, the sensing stations may be in a configuration identical to that of the fully automatic, on-line unit. In a manual version of the stand-alone unit, the samples are manually gathered and manually placed into contact with the various sensing stations. The information reported by the stand-alone units can be used to manually control the operation of the gin.

摘要： A fiber quality monitoring apparatus is constructed with a sample window for viewing a fiber sample. As the fiber sample passes the sample window, a bulb is strobed to produce a light pulse that is directed toward and reflected by the fiber sample. When the light pulse reaches a desired intensity, a first photo diode generates a synchronization signal. A second photo diode detects reflected light with a wavelength between about 500 nanometers and about 600 nanometers and produces a reflection signal. A third photo diode detects reflected light with a wavelength between about 430 nanometers and about 530 nanometers and produces a color signal. A charge coupled device camera is positioned to receive the reflected light pulse. Pixels below a desired value are designated as dark pixels and pixels receiving the reflected light pulse at an intensity greater than the desired level are designated as light pixels.
