Printing And Dyeing CNC Enters A New Era Of Comprehensive Automation

A number of products developed by Changzhou Hongda science and technology group have been authorized by the national invention patent of the automatic printing system, automatic assembly system, on-line detection and control system of moisture content based on machine vision technology. At present, the enterprise uses the powerful advantage of information and digital automation technology, constantly using advanced technology to arm traditional enterprises, and actively develops in automation, intelligence and information technology, develops products with independent intellectual property rights, has absolute advantages in the domestic market, and leads the new trend of industrial technology development. All along, how does Changzhou grand live steadily? Printing and dyeing industry The leading position reporter interviewed the Changzhou Hongda Group Chairman Gu Ren with these questions.

Reporter: what is the emphasis on the production of Hongda Company in 2013? Is it a continuation of the previous production mode, or is there a new direction for R & D?

Gu Ren: this year, there are three key points for the ambitious products: one is the precise water consumption system. The two is cloth inspection system. The three is the intelligent steam system. The current sales volume has increased by about 20% over last year. Now the customer's demand for product quality is getting higher and higher, and the increase of labor cost and uncertainty of personnel will bring some cost pressure to the enterprise. If enterprises want to achieve good results, they can only rely on the intellectualization and automation of the equipment. Improving the technological content of equipment and reducing dependence on people are the inevitable trend of market development. The company's products generally improve the automation level of the printing and dyeing industry from three levels: one is the supply parameter detection of key points at all levels; the other is the intellectualization and automation of the production platform; and the three is to realize the intelligent information management and control of the whole production process.

Reporter: what are the main measures taken by enterprises in the fields of products, marketing, R & D and so on? What advantages do the products have in terms of performance characteristics?

Gu Ren: this year, the enterprise mainly focuses on the automatic flower control system, image inspection system and precise water consumption online measurement and control system. The automatic flower matching system of the rotary screen automatic printing system can realize automatic printing of the printing machine. It can detect the defects of the color pattern of the printing pattern in time and adjust it in time. printing Continuous and error free operation. The system uses the median filter to preprocess the collected flower image, and uses the combined algorithm based on optical flow and phase correlation to detect the color position of the printing pattern in real time, further improving the accuracy of the flower and improving the efficiency and accuracy of the printing equipment. The product has sold more than 30 units in the first half of this year, and the company has increased investment in research and development and achieved some results.

Image intelligent cloth inspection system is mainly used for monitoring the quality of cloth in the production process. The smart camera is used as the detection sensor of the device to monitor the cloth in motion, and through a series of image processing processes, the current defect information is obtained and compared with the standard. When the range is out of range, the alarm is automatically given, and the test data is stored in the database. It can realize defect detection, defect record, defect alarm, fabric width real-time monitoring, door width data recording and preservation functions. The system can meet the requirements of enterprise production process automation and enterprise quality requirements, realize automatic monitoring of cloth quality in production process, greatly improve production efficiency, realize energy saving and emission reduction from the source, and achieve low carbon production.

The precise water consumption on-line measurement and control system adopts the form of high precision electromagnetic flowmeter and proportional valve. The washing process is detected by using the cleanliness sensor. The water flow is precisely controlled, especially in the process of water pressure change, vehicle speed change, start-up, downtime, fabric weight, door width or variety replacement. The water flow of the system is automatically adjusted to ensure the cleanliness of the washing tank is basically stable. The online detection and control of water consumption in the process of washing are effectively realized, and the transformation of water flow from artificial fuzzy control to quantitative control is realized. Under the condition that the process is stable, the general water saving can reach 20%~30%, and the quality of products is greatly improved.

The company has a well-established sales network. Its products are in Zhejiang, Shandong, Jiangsu, etc. Spin Printing and dyeing enterprises in key provinces have been successfully applied, such as Jining Ruyi printing and dyeing Co., Ltd., Qingdao Phoenix Dongxiang printing and dyeing Co., Ltd. The company also has a professional after-sales service team, responsible for the maintenance of our company's series products, and regular after-sales service personnel for new product business training, in order to better serve the users.

Reporter: what do you think of this year? Textile market Situation?

Gu Ren: I think the textile industry will never go downhill. The concept of downhill is phased. This is the process of technological progress, the process of new and old replacement, and the textile industry as a whole is still making progress. The market is relatively bad at present because the cotton price is upside down, and then leads to a series of problems. Cotton price The changes will make the export of mid end products difficult, so the whole upstream and downstream will be implicated. The current era is changing constantly, and the textile industry also needs to make great progress. We are now developing intelligent on-line monitoring system for D-Z800 ring spinning quality.

It is understood that the spindle of domestic spinning frame has nearly 120 million spindles. To detect the yarn of each spindle, it can only be measured by the Ulster instrument, but there is no way to modify it. The machines we are producing now can be tested on every instrument, and can help remove or re adjust the poor spinning place, which virtually saves a lot of costs. The intelligent online monitoring system for the quality of D-Z800 ring spun yarn can realize on-line automatic monitoring of yarn breakage of spinning frames, effectively reducing the waste of cotton and the energy consumption of spindle running. According to customer needs, different levels of system services are provided, which greatly improves production efficiency compared with the inspection of truck drivers.

Reporter: how do you view the issue of industry upgrading and transformation? What are the future plans of the enterprise?

Gu Ren: at present, the state is right. Printing and dyeing industry The threshold has been raised, and the cost of labor and energy consumption has accelerated the transformation and upgrading of enterprises. 10 years ago, our product ran towards the goal of saving energy and reducing consumption. Today, it is also an opportunity for our products. In the past, our products were more expensive and some customers thought it was unworkable. They thought that employing more workers could solve the problem of production efficiency. Now the task of energy saving and emission reduction is becoming more and more serious. There are many technologies that can not be done by manpower. In addition, the adjustment of new emission standards of the Ministry of environmental protection is very stressful to enterprises, and it must fundamentally improve the automation, intelligence and digitalization of machinery.

The professional problem of printing and dyeing industry is the problem of one-time accuracy. One success rate is to solve the problem of energy conservation and emission reduction from the source. At present, the success rate of a business is not very high. Some varieties require high grade. The success rate is about 70%. The 20%~30% cloth needs to be processed two times or even more times to meet the quality requirements. To improve the success rate, intelligent online detection and control system is needed.

Over the years, enterprises have been doing automatic inspection and automatic control around the production site. According to the needs of users, it has been upgraded from the previous point and plane detection to the comprehensive automation and comprehensive automation system. The future competition is the competition of intellectual property rights. For textile machinery enterprises, as long as they can produce, there will be benefits. Now some enterprises are still at the level of production, and the future depends on whether your technology can win in the industry competition.

With intellectual property rights supporting the development of an enterprise, enterprises can go far. Transformation is innovation, and intellectual property rights are the needs of state and enterprise transformation. Changzhou Hongda has gone through 25 years of development. Now it has become the two integration and demonstration enterprise of the Ministry of industry and information technology, the national R & D center of printing and dyeing digitalization system, and the social practice base for doctoral students of Tsinghua University. R & D investment accounts for about 8% of sales. Enterprises have been striving to create new technologies and lead the development of the industry.
