Definitions

  • the invention relates to an artificial vision system developed for real-time detection of abrage errors during the production of yarn coils.
  • abrage occurs as a result of accidental mixing of raw materials used in different stages of yarn production (blending or coiling stage). If the abraged coils are converted into fabric form, errors with color differences occur after the dyeing process. Abrage errors are visually controlled by quality control personnel both on the coil and on the fabric in the enterprises. This process is a tiring process that takes a long time, and many abraged products cannot be detected because of personal errors such as distraction or fatigue of the personnel performing the control of the process. In addition, evaluations made in the detection of errors are subjective.
  • the coils are individually subjected to abrage control in a room illuminated by UV rays.
  • approximately 7500 pieces/day coils are controlled in an enterprise producing an average of 15 tons of yarn per day and at least four workers are employed for this task.
  • a result of fatigue or distraction of the worker many abraged products cannot be detected and this causes serious cost and prestige loss.
  • manual controls on yarn production lines containing automation systems interrupt the automatically advanced workflow. In this case, automatic abrage control systems need to be developed in order to increase production efficiency, save labor costs and minimize the abrage control errors.
  • US5138151A deals with a method of detecting inappropriate, irregular parts of all yarns in a package.
