The whole scheme has a good performance-price ratio, which greatly improves the automation level of domestic loose winders, and the main technical indicators have reached the level of similar foreign equipment. Brief introduction of the system control scheme Take the single spindle control as an example.
The principle of Hangzhou Jingbian Technology Co.,Ltd. the system control scheme is shown in Figure 1. A traverse motor shaft is connected to a steel wire wheel. The forward and reverse rotation drive of the steel wire wheel is fastened to the wire guide to move left and right. The traverse movement of the yarn; the winding motor directly drives the bobbin to rotate to realize the winding movement of the yarn. After the two traverse and winding movements are combined, the yarn is wound back and forth in the shape of a spiral. On the surface of the bobbin. The tension compensation motor and the overfeed motor are mainly used to control the tension during the winding process of the yarn. In this solution, the traverse yarn guide motor uses a uniquely designed ultra-small inertia servo motor. The winding and super-feed motors also use specially designed and customized high-speed brushless DC motors. The tension motors use a common stepper. Motor.
The “single-spindle control drive” in the picture is based on a fully digital permanent magnet AC servo driver developed by Hollysys embedded with a high-speed electronic yarn guide motion control algorithm for a precision winder, and a brushless motor for winding. Special motor drive control system for speed control and yarn tension control strategy. The whole system has a simple structure and complete functions. Adjusting the internal memory parameters of the ‘single spindle control driver’ through the keyboard or communication can conveniently set the geometric parameters of the yarn winding forming (full bobbin diameter, edge width, etc.) and the linear speed of the winding. , Winding ratio, reciprocating stroke length, different width, differential period, differential cam curve and other technical parameters of the bobbin hard edge trimming.
It also has three communication interfaces RS232, RS485 and CAN bus, which can be very convenient. Complete multi-spindle networking control to fully realize flexible digital winding.
