 In the weaving line the automated process comprises of six production stages that include winding, warping, sizing, weaving inspection and packing and out of these stages there are 16 points of automation. Again out of these, 12 are related to the materials handling or transport and four applications deal with automating the machine operations themselves. This includes the automated process control the slasher and the weaving functions of (1) Automatic Pick Repair (2) Automated Warp breakage Locator and (3) Computerized Machine Control. But no doubt, manual assistance is still required for beam replacement and repair of the warp breaks.
Online Quality Control
The one and only factor for success of an automated textile mill is online quality measuring, monitoring and controlling practices. Now more and more companies are implementing the modern technologies to monitor the quality of the product at each and every stage, so that in case of any problem, it can done at that stage itself rather than after the product output has been done.
The importance of online monitoring and quality control cannot be over emphasized as the online monitor would incur huge expenditure to the company and the production also should be inline with the implementation of the online quality control process.
With the current technology one could now produce million pieces per day and if any defect is not identified at an earlier stage or process the whole output would go down the drain which results in wastage and unnecessary expenditure to the company. So the online quality automation process is a must for any textile manufacturing line. Should the off-standard material remain in the production line, further deterioration in product quality can take place, foreign-matter, broken filaments or unevenness can be found in the downstream processing.
Some times there is a problem of machine stoppages for long periods of time if the detection of the problem is not done very that stage itself, then it would adversely affect the production of the day. To achieve the premium quality it has become imperative for the textile manufacturing companies to incorporate online quality detectors that can measure quality on a regular basis and adjust machine settings within prescribed tolerances to maintain all the nominal quality parameters prescribed. In the event that the instruction is not being followed then stoppage production is done and correction is made manually.
The more recent advances in the field of imaging technology have fructified into inexpensive, high quality image acquisition and advances in computer technology now allow for image processing to be performed quickly and cheaply. This has given rise not only to a number of developments for laboratory quality testing equipment for fibers, yarns and fabrics but also it is playing a major role in the development of online equipment for continuous monitoring of quality in textiles such as Fiber Contamination Eliminator, Intelligent Yarn Grader and Automatic Fabric Inspection etc.
