Quality Monitoring System
The uniformity of yarn/sliver along the length is monitored by this system. The system gets inputs, from the user through the HMI. Also the deviation parameters are displayed in the HMI. The user can monitor the yarn for 4 different lengths. The CV% , U% , Number of Thin places per km, Number of Thick places per km and Number of Nep places per km will be displayed in the HMI. The material can be monitored for up to 4 different sample lengths simultaneously. It is possible for the sampling to be as close as about 10 mm at material speeds of around 600 m/min. The monitored values are calculated all the time online for a sliding window of the length specified. If the speed the material is less than 1 m/min, then monitoring process stops and will resume only if the speed of the material is greater than 1m/min . The values are then displayed on the HMI.
