Spinning is the process of conversion of fibre into yarn. The spinning process includes various operations such as cotton mixing, carding, combing, drawing, winding. Winding is the final process in spinning mill where the yarn of small quantity is wound into a big package known as cones. The important aspect in winding is removal of defects or faults in yarn produced. In manual winding when there is discontinuity of thread, during removal of faults, the knot is made by a human. This reduces the quality of yarn. To overcome this disadvantage, autoconer is used. Autoconer is an advanced machine used in winding process to get a high quality yarn with low man power. Here, threads are spliced automatically. Splicing means the process of opening of broken ends and retwisting the ends after the removal of faults. Here the joined yarn looks like parent yarn. Thus, the quality of yarn is enhanced. The drawback of autoconer is, waste collected by suction motor gets deposited on the suction panel and it should be disposed manually for a periodic time interval. If the waste is not removed it reduces the operating efficiency of the suction motor. This leads to reduction in quality of yarn. The aim of the proposed work is to design an automatic waste removal system using PLC (Programmable Logic Controller) which helps us to further increase the efficiency of the suction motor and thus the quality of yarn.
