The New Suzhou Lun Cotton Spinning Project Has Made The Doffing Stoop Bend To Zero. 10000 Yuan To Reduce Employment By 50 People

Shen Caiying is a doffing worker in the front spinning workshop of Suzhou Zhen Lun cotton spinning Co., Ltd.. Every time she stops doffing for more than 10 minutes, she has to stoop and take the cone, then bend down and empty the cylinder. She is skilled, deft, and natural. She acts at least 5000 times a day. From the second production lines of the automation and reconstruction project of the past few days, the doffing process only needs to be delivered on the machine operating platform, and the doffing workers no longer need to stoop to pick up the cylinder and put the drum out.

With the completion of continuous production and transformation processes such as blowing carding and thin chain connection, the Lun Lun cotton spinning started the key step of intelligent interconnection in April this year, the automation transformation of coarse and fine parts; the first production line was put into operation in July; at the end of October, with the second production lines being fully put into production and commissioning, it marked that automatic spinning completely replaced the manual labor and reduced the employment of the million spindles from 60 to 70 to less than 20 people.

All of the doffing bowed movements are "zeroing".

In traditional people's impression, the cotton spinning industry is a labor-intensive industry. The workshop is full of flying objects. The truck driver has been pulling hands and shoulders, working environment is poor, and the labor intensity is great. Now, the workshop of Zhen Lun biomass Fiber Co., Ltd. is a modern production scene. The spinning machine of different shapes is running at high speed, and the workshops are in constant temperature and humidity.

Huang Jianxiang, deputy general manager of Zhen Lun cotton spinning, introduced:

"The traditional cotton spinning production is divided into 6 processes, namely, flower cleaning, carding, drawing, roving, spinning and winding. The shock fiber has begun automation transformation more than ten years ago, and has completed the interconnection of production processes such as blowing carding and fine spinning. "

After deciding to set up the Synthetic Fiber Co., Ltd., Zhen Lun invested heavily in the production process transformation. Since April this year, the company has invested about 10000000 yuan in Suzhou cotton spinning enterprise first completed the automation transformation of thickness and thickness, the company workshop has become the provincial intelligent manufacturing demonstration benchmarking workshop. "Before pulling out the roving full of roving, placing it in the conveyor car, and then dropping the empty cylinder, about 4 to 5 tons per person per class and bent over 5000 times, one day is definitely a backache." Shen Caiying said that after the transformation of the thickness and automation system, the automatic doffing roving machine had completed these movements for them, and all the stooping movements were all zeroed.

The output per unit increased by more than 10% per day.

The reporter saw in the pre spinning workshop, which had been completed in the transformation of thickness and automation. An employee pressed the button, the equipment began to run automatically, the semi finished roving tube was automatically removed one by one, and the empty roving tube was automatically cleaned up after the tail yarn cleaning machine was automatically cleaned, and it was automatically returned to the frame of the roving machine.

The fully automatic doffing roving machine solves the problem of high labor intensity of doffing plug and empty pipe and manual roving full roving. The matching with roving conveyor system can really achieve the thickness and thickness. Different kinds of roving can be automatically and precisely conveyed to different kinds of spinning frames. The automation transformation of thickness and thickness not only greatly reduces the labor intensity of employees, but also improves the efficiency of machine production and improves the quality of products. At the same time, when the original roving was sent to the downstream spinning process through the transport vehicle, different varieties of people appeared to send the wrong machine platform. During the transportation process, the roving surface of the semi finished products was also prone to produce oil pollution risk, and the risk of roving surface being shaved or damaged by grinding was solved, and the product quality was further improved.

Gu Zhiming, deputy general manager of Shenzhen polyamide cotton spinning Co., Ltd., which is responsible for upgrading the thickness and joint project, introduced:

The daily output per unit increased by 10% to 15%, and the production efficiency increased from 85% to 95%.

The semi finished roving tube, which is replaced on the spinning frame, needs to be removed in batches and transported to manual roving yarn cleaning machine one by one for manual cleaning. The working process is cumbersome and there are many transportation vehicles. After the transformation, the staff can increase the production efficiency greatly by simply passing the "one button delivery" button through the coarse and fine conveying system. The original doffing time is 15 minutes to 20 minutes, and now it is shortened to 2 to 3 minutes. It improves production efficiency and stabilizes product quality.

"One step away" to achieve full automation

Cotton spinning is not a high-end industry, but it must be high-end.

This is the strategic positioning made by Shen Peirong, chairman of Zhen Lun cotton spinning, in 2003. He once said that cotton spinning enterprises must take the green development road of "high starting point, rapid development, high efficiency, low consumption and zero pollution".

It is understood that since 2006, the total investment of Zhen Lun in the industrial transformation and upgrading, equipment and technology transformation has exceeded 1 billion 500 million yuan, and the production process 100% self leveling and on-line testing has been realized, so as to achieve continuous, automatic and intelligent spinning production. This year, under the complicated and severe economic situation, the yarn of Lun cotton spinning has become the designated product of many famous clothing enterprises both at home and abroad, and has always been booming in production and marketing.

16 years later, from the early stage of the establishment of the first 4 spinning machines and 1680 ingots, the Lun cotton spinning has developed into a model of transforming traditional industries with modern technology. 3 provincial intelligent manufacturing demonstration workshops have been built, and 1 intelligent manufacturing benchmarking workshops have been built. At present, Zhen Lun cotton spinning has 3 wholly-owned subsidiaries in Wujiang, with 1300 employees and 500 thousand production capacity. The annual output of pure spinning and blended yarns is 80 thousand tons, with annual sales income reaching 1 billion 800 million yuan.

Huang Jianxiang told reporters that as chairman of the cotton textile industry veteran, chairman Shen Peirong has always had a complex: let cotton spinning enterprises no longer give people the impression of chaos and dirty, the truck drivers no longer become bitter pronouncement of fatigue and fatigue. In the past 16 years, Zhen Lun has been working hard to invest in huge amounts of money for automatic transformation. Now, with the seamless convergence of the main processes and the "intelligent interconnection", it is only one step away from the whole process of automation. With the development of science and technology and the continuous development of Zhen Lun, cotton spinning industry will usher in a new era.
