Bobbin initial position-based operation control method and system for bobbin winder Technical Field The invention relates to the technical field of winding machines, in particular to a winding machine operation control method and system based on an initial position of a bobbin. Background The winder is a special device for winding larger raw yarn into conical or cylindrical bobbins with proper tension and winding distance in the textile industry. At present, when a bobbin winder works, after a bobbin to be wound is manually installed to a designated station, raw yarn is conveyed through an overfeeding motor, the raw yarn is guided through a swinging rod according to a preset target winding distance and is stably unwound until the yarn unwound from the bobbin reaches a preset capacity, and then the bobbin is replaced, so that winding is completed. Because the spool can be worn and torn or produce deformation after frequently changing the use, lead to every spool to install the position after the appointed station and all have the difference, the yarn twines and produces the phenomenon of "big or small head" easily behind the spool this moment to produce extra tension fluctuation, can rub each other when making the yarn wrap and unwind and produce the galling phenomenon, and then lead to the whole quality reduction of winding yarn finished product.
