Textile Machinery Industry Speeds Up Automation Product Upgrading

China's textile machinery industry can be described as a fully competitive market. If any enterprise wants to be eliminated in such fierce competition, it must speed up the pace of product structure adjustment and enhance its core competitiveness, which also brings certain opportunities for automation product providers.

According to the data released by the National Bureau of statistics, the copyright of the engineering network is controlled. In 2009, textile machinery continued its downward trend in 2008, with slow growth, coupled with the competition of foreign products and the impact of the global financial crisis, Chinese textile machinery enterprises are facing severe challenges. By the first quarter of 2010, the textile machinery industry fell slightly, down by about 5%~10%, an increase of over 70% over the same period last year. Under the dual influence of exports and domestic demand, the growth rate is expected to increase slightly in the second quarter of 2010.

The decline in the textile machinery industry has had a certain impact on the supply of automation products. Information from the National Bureau of statistics shows that the total market size of automation products in China's textile machinery industry in 2009 was close to 2 billion 400 million yuan, reaching 2 billion 390 million yuan, down 7% from 2008. But in the first quarter of 2010, the textile machinery industry automation product market grew by 70.5% compared to the same period last year, a decrease of 9%.

As far as textile machinery products are concerned, the market capacity of traditional textile machinery with a low technical content has been greatly reduced, and the textile machinery products with high efficiency, energy saving and high added value have been greatly improved, which has brought a certain market for automation products.

Distribution of automation products in textile machinery industry

The survey also shows that the larger the scale of textile machinery manufacturing enterprises, the wider the product coverage, the higher the level of automation and information, the more automation products they use.

Automation is the only way to improve the performance of mechanical products and enhance the competitiveness of enterprises. With the development and application of computer networks and power electronics, its importance is increasingly prominent. Its application in textile machinery will be more and more extensive. The survey results show that more high-end textile machinery manufacturers have gone from the initial application of PLC, inverter, servo and other single automation products to the demand for comprehensive application of multi automation products and equipment network digital integrated manufacturing.

Most enterprises involved in the survey said that in the first quarter of 2010, the textile machinery industry had fewer new products, but in the second half of the year, the demand for the project control network was copyrighted, and the investment in new product research and development was expected to increase. However, most of the enterprises in the past have made technological improvements or upgrading before they continue in software and machinery. Considering the reliability and stability of the products, they basically do not change the configuration and brand of automated products.

The survey shows that the brand coverage of automation products used in the textile machinery industry is very wide. From SIEMENS, ABB, MITSUBISHI to Begala, Delta and Lenz, almost all automatization manufacturers can find their own users in textile machinery enterprises. The questionnaire also showed that at the same time, more than three automation brands were used by the same textile machinery company at the same time. The questionnaire from Shanghai Textile Machinery Co., Ltd. showed that the brand of the automation products they used involved at least 8 brands, such as SIEMENS, ABB, Begala, Feinikesi, MITSUBISHI, Schneider, OMRON, Fuji motor and so on. At the same time, smaller textile machinery enterprises, such as Changzhou Tonghe Textile Machinery Manufacturing Co., Ltd. also used at least three brands, including MITSUBISHI, Delta and Lenz.

Textile machinery enterprises purchase automation products

64 textile machinery manufacturers involved in the survey said they would purchase new automation products in the coming year.

The survey shows that 55 enterprises will consider buying motor and drive device in the near future, accounting for 85.9% of the surveyed enterprises. Frequency converter, as the main driving device, has the largest demand in the textile machinery automation market. Previous data showed that textile machinery Users need 80 thousand to 90 thousand general frequency converters in one year, and the dedicated frequency converters for components such as weft accumulator and slot can meet tens of thousands of demand each year.

At present, AC frequency conversion technology is increasingly becoming the mainstream mode of driving three-phase asynchronous motor, and the growth rate of low voltage inverter is higher than that of automatic product growth. There is still a certain gap between China's frequency converter technology and developed countries. The market of low-voltage inverter in textile machinery industry can be said to be firmly owned by Taiwan and Japanese manufacturers. CONTROL ENGINEERING China has all rights reserved. China's frequency converter manufacturers should seize the opportunity of upgrading and upgrading products in textile machinery and other industries for nearly two years to improve their strength. {page_break}

Of the automation products planned for textile machinery, second of them are industrial control products, and 52 enterprises will buy related products in the near future. The survey shows that the industrial control products currently used by textile machinery enterprises are mainly PLC (64), servo system (55), human-machine interface (48), industrial Ethernet (38) and field bus (32), and the use of industrial control computer and machine vision is relatively few, 10 and 20 respectively, accounting for 15.6% and 31.2% of the participating enterprises. Previous surveys show that most textile equipment can meet the control requirements of production process with PLC. Only a few devices have used industrial control computer and PLC to form control systems in order to achieve more complicated control requirements, such as sizing machine, new roving machine and some chemical fiber equipment.

According to experts from the textile machinery industry, the main demand for textile machinery is the various looms. Each loom has a small PLCwww.cechina.cn on the average, which is mainly used for related detection, alarm, speed control and machine start and stop. Although the number of spinning machines is less than 5% of the total number of textile machinery, the PLC used on the spinning machine is relatively large, and a single spinning machine usually uses more than ten PLC. The number of carding machines is about 12% of the total spinning machine, mainly using small PLC control. Other types of textile machinery are basically controlled by PLC, and some relatively simple equipment uses single chip microcomputer or other control methods. However, with the upgrading of the textile machinery industry, the application of special controller and IPC, especially the application of the fan free industrial control machine, is gradually gaining popularity in the textile machinery industry.

In addition, 31 enterprises said they would buy the corresponding software, 30 enterprises said they would buy power supply and voltage stabilizing equipment, and 26 enterprises would purchase automatic instruments. There were fewer enterprises selecting general electrical equipment, only 15. In the subsequent telephone survey, respondents said that the products of general electric appliances, electrician and other basic products were not updated rapidly. CONTROL ENGINEERING China had all rights reserved, and the procurement department often procured ahead of schedule when the production started.

　　 Spin How to choose automation products for machinery manufacturers

The results of the questionnaire survey on how to select products are consistent with the findings of today's automation in various industries. 6 respondents ranked brand awareness as the first factor, while the most important factor of technical support and service ranking showed textile machinery users' recognition of automation brand. Among the 15 respondents who ranked technical support and service as the first factor, 8 also ranked brand awareness as the most important factor. In addition, among the 40 companies surveyed, 50 readers ranked the price as the second factor affecting choice. The reliability and stability of products have become the most important factors for textile machinery enterprises to choose automation products. 60 readers regard this factor as the first element. Besides, the cost of technology training and later maintenance is another factor to consider.

The 4 surveys conducted by various industries show that mechanical users have become more sophisticated in choosing automated products.

As an automated product provider, what aspects should we take to provide services for the users of the textile machinery industry, so as to expand the market smoothly? In this survey, 75 participants explicitly expressed the hope that the automation product providers could provide case analysis and product design services, and 60 indicated that the successful cases were helpful for their practical work. 。 The survey participants agreed that the supplier of automation products should regularly conduct technical and case training.

Bian Guixiang, deputy general manager of Yancheng City Textile Machinery Co., Ltd., told reporters: "the popularization of knowledge carried out by ordinary seminars held by automated manufacturers is very meaningful for the general technical personnel. But for advanced technology engineers of textile machinery factories, we often need further detailed application and design of knowledge ritual. However, the deeper technology training of automated manufacturers often needs to be charged. It is hoped that automation enterprises can provide more technical support and services to our textile machinery plant.

In the actual production, the system maintenance cost caused by the instability of the system has become a consensus. 90 readers have chosen this item. Just like the previous survey results, respondents generally believe that the frequent modification of software and the increase of maintenance frequency caused by the instability of the system affect the efficiency of production. Therefore, whether the suppliers of automated products can provide timely services has become a factor in considering the choice of products by textile machinery manufacturers.

And by reporters during the exhibition visit, found that from the time to participate in this Spin From the perspective of textile machinery products, as the latest textile machinery and equipment developed in the world, these products not only reflect the automation and continuity of production process, but also have the characteristics of energy saving, high efficiency, green, environmental protection and so on.
