Shuttleless looms, air jet looms, rapier looms, water jet looms, and projectile looms are commonly known as weaving machines. The shuttle control and take-up control (i.e., weft control) of the webbing machine is a typical motion control technique. Over the years, the import volume of China's shuttleless looms has been relatively large. For example, air jet looms import more than 10,000 units per year, and rapier looms import more than 5,000 units. These two mechanical standards are equipped with electronic delivery and electronic coiling. Most of them adopt AC servo system as the precise control of the delivery volume and weft density. Because the speed, production volume and efficiency of the machine are all high, the original mechanical delivery and mechanical coiling cannot meet the process requirements, and high precision must be adopted. Motion control technology. Although domestic shuttleless looms manufacturers have successfully developed servo systems for electronic delivery and electronic coiling, but because the level of machinery itself is lower than that of imported machinery, electronic delivery and electronic coiling are mostly used as optional parts. . With the improvement of the mechanical manufacturing level of domestic shuttleless looms, electronic delivery and electronic coiling as a standard configuration is an inevitable result, then the demand for servo systems by domestic shuttleless looms will increase rapidly.
The promotion and application of automation technology has enabled the technology level and variety adaptability of shuttleless looms to continuously create new levels, so that the operation of the looms can be automated, such as the program control of the switch car, regular automatic refueling, automatic collection and display of the looms by the microcomputer. Various production parameters and operating conditions, including speed, production, efficiency, stoppage and cause analysis, weaving shaft warp stock, woven fabric packaging, etc., thus improving management and improving production efficiency; electronic delivery and The electronic coiling constitutes the automatic control of the warp tension, which basically eliminates the latitudinal defect; the electronic color selection, the microcomputer automatically changes the texture structure, and the fabric pattern is changed centrally, and the group control can be realized by the two-way communication between the single machine and the center console. According to reports, some manufacturers began to study the automatic detection of latitude and latitude outside the shed, as well as the automatic detection and elimination of online menstruation. It has been predicted that it is possible to achieve complete automation of weaving production without a long time.
