Modular Intelligentization Is The Development Direction Of Loom

The textile industry "12th Five-Year" science and technology tackling and industrialization project: there are 6 parts in the new weaving equipment: the new modular shuttleless loom, the high-speed towel rapier loom, the high-speed towel air-jet loom, the double deck loom, the mechatronics special loom and the carpet rapier loom. This is the continuation and refinement of the 3 major weaving technologies and equipment in the new textile machinery issued by the 4 ministries and commissions of the Ministry of industry in 2009.

These projects are

Modularization design concept and Application

Modularization of shuttleless looms abroad

In recent years, Japanese Tsuda Ko and Toyota Corporation's jet and water jet looms have also adopted some "common modules". Through the full application and promotion of the modularization concept, the strain energy of products to respond to the market quickly, personalized customization and cost reduction has been greatly enhanced, which has been well demonstrated in foreign rapier and air-jet looms, and is an efficient production technology.

At present, the domestic high-end rapier models have a high starting point, and are more integrated with the modular design concept of European models, which are very beneficial to the expansion and serialization of the models to the Terry and industrial fabrics. The domestic air-jet looms are used as the technology of importing Japanese manufacturers during the "85" period, and the two common weft insertion methods of rapier and jet are not available in the short term. The high efficiency production technology will bring quick and efficient market strain to the homemade shuttleless looms and accelerate the development of domestic rapier and air-jet looms.

Information and intelligent control system

Rapier and air-jet loom control system is a highly integrated system of information technology and mechatronics technology. Data acquisition, operation processing, feedback control, human-machine interface and so on are the main functions of the control system.

In recent years, the most prominent progress of product control system upgrading is information integration and intelligent technology.

The in-depth application of information network technology makes loom operation, management and maintenance more convenient, and the efficiency and efficiency of management are improved obviously.

The intelligent weaving system of the new generation rapier and air-jet loom is a "expert system" that closely combines control system and weaving process. It stores various empirical parameters of fabrics, and can store new parameters to enrich the system. With the input of fewer weaving parameters, the system automatically calculates the necessary weaving parameters and guides the loom into the best working state to achieve production and finish weaving process.

This is not only convenient for users, but also improves work efficiency and ensures product quality.

Information network technology is a higher level of computer technology application of foreign high-end shuttleless looms. Most foreign high-end looms have functions of network and weaving management; LAN can realize group control of looms, managers can conveniently query various weaving production data, loom running state, process data can be pmitted between looms, remote diagnosis of looms with faults, and timely troubleshooting of some faults; remote communication can also be realized through the Internet.

The information network technology is the high-end control technology that needs to be perfected in the domestic high-end loom control system.

Through efforts, in the near future, the domestic looms will be able to produce an informationalized and intelligent control system that is consistent with the national conditions and practicability.

Application of high efficiency and low consumption technology abroad

After efficient production of foreign looms, after highly mechanical and electrical integration, electrification of moving parts and intelligent control system, besides improving efficiency directly from high speed, the weft insertion system of looms has been improved. It has adopted a number of technological innovations to improve the efficient production capacity of looms.

Weft tension program control technology.

The peak value of weft tension is generated when rapier, shuttle and air-jet loom are weft at each time.

These tensions will increase the breaking rate of weft yarn at high speed.

The weft program tension controller, which is controlled by stepper motor, is installed at the yarn outlet end of the weft feeder, which can compensate for the tension. It can obviously reduce the peak value of weft tension and adapt to high speed weaving, especially for weaving weft and elastic yarns.

At present, the weft program tension controller has been widely applied in shuttle shuttleless machines abroad. The products of the wholly foreign-owned enterprises in China are displayed and the price is very competitive.

Auxiliary device for air-jet looms.

The automatic switchover, weft automatic processing, remote diagnosis, automatic speed regulation, electronic weft scissors and other devices on the air jet looms are effective measures to improve equipment efficiency and reduce production costs. These measures are being accepted by users and become the standard configuration of air-jet looms.

Domestic enterprises should speed up the research and development of these technologies and speed up the automation and intellectualization of looms so as to cope with the increasingly tense domestic labor force.

Air jet looms are large energy consumers, most of which are consumed by compressed air.

At present, most domestic and foreign air-jet looms mostly control the opening and closing time of the main and auxiliary injection solenoid valves and the time of the air injection by controlling the weft insertion process dynamically and precisely, so as to achieve the goal of economizing energy consumption.

The L-5500 air-jet loom has been introduced to the market in Italy Itema-Sultex (IDA Suhl Shou) company. The design is innovative. It starts to detect the flying speed of the weft before weft enters the shed and calculates the location of the weft flying. The control system can automatically adjust the main nozzle, the main nozzle and the auxiliary nozzle in the weft insertion process at the current weft insertion process, and does not need to adjust in the next weft. Therefore, it can effectively reduce the consumption of gas, reflecting the unique technology level of rapid detection, quick processing and quick response. At the same time, the weft yarn has little force and can meet the requirements of weft weaving.

In addition, foreign jet looms are supplemented by high thrust main nozzles, porous auxiliary nozzles with good airflow cluster, 1 electromagnetic valves to control 2 auxiliary nozzles, shorten the gas path and reduce the volume of electromagnetic valves, so as to reduce the consumption of gas.

Domestic air jet looms can learn from advanced foreign technologies, improve the level of control system, and do in-depth research on related technologies, such as rapid detection technology, data processing, control software and servo valves. The quality and technical level of supporting equipment, such as domestic main nozzles, auxiliary nozzle, solenoid valves and electronic components, must also be improved simultaneously, so as to achieve the maximum demand of saving energy and reducing consumption.
