    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： An apparatus measures moisture content of cotton based upon rates of electrical charges flowing through the cotton. The apparatus includes a moisture sensor having first electrodes, second electrodes, and ground electrodes which are interdigitated between the first and second electrodes. The apparatus also includes a moisture content determination circuit that provides first electrical charges to the first electrodes, and second electrical charges to the second electrodes. The moisture content determination circuit determines the rate of electrical charge flowing from each of the first and second electrodes through the cotton to the ground electrodes, and determines the moisture content of the cotton based upon the rates of electrical charges flowing through the cotton. By thus applying first electrical charges to the first electrodes and second electrical charges to the second electrodes, the apparatus accurately measures the moisture content of the cotton over a wide range of moisture contents. This wide range is achieved by setting the first electrical charges of the first electrodes to a level which is optimal for moisture levels at the upper end of the desired measurement range, and by setting the second electrical charges on the second electrodes to a level which is optimal for moisture levels at the lower end of the desired measurement range.

    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.
