The Intelligent Doffer Car Has Good Prospects For Popularization.

< p > Miu Dingshu: former Suzhou Su Lun a target= "_blank" href= "//www.sjfzxm.com/" > textile /a /a plant chief engineer, who was appointed academic member of China Textile Engineering Society cotton textile Specialized Committee, director of Jiangsu textile engineering society, Secretary General of Suzhou textile engineering society, a target= "_blank" href= "target=" of Jiaxing University, guest professor of clothing and Art Design Institute, Xuchang science and Technology Commissioner, Henan Jiangsu Textile Co., Ltd. general worker, Tianhua enterprise development (Suzhou) Limited company spinning innovation technology consulting center, chief engineer and technical director.

< p > at present, < a href= "//www.sjfzxm.com/news/index_c.asp" > spinning machine > /a > automatic doffing forms can be divided into two main categories: one is the automatic doffing of long spinning cars, that is, the collective doffing spinning long car; the other is the automatic doffing pformation of the spinning short car, including: the doffing device of the conventional car, the collective doffing device of the spinning short car, and the intelligent falling cloth car device.

< /p >

< p > traditional car doffing device mainly has two types: hand push doffer car and electric electromechanical integration doffer car.

To a certain extent, they have improved production efficiency and reduced the labor intensity of workers. They are characterized by simple structure, low investment and low power consumption.

However, because the car adopts the pre loosening plate and doffer to shovel and lift the structural form of the bobbin, it is easy to damage the spindle and the damaged tube yarn surface. The components are easy to walk and the overall stability is poor, so it is difficult for the enterprises producing high quality yarns to accept it.

< /p >

< p > spinning short car collective doffing device is mainly used for old machine pformation, and solves the problem of automatic doffing, so that every spindle of the whole spinning frame is pulled out at the same time and at the same time, the doffing efficiency is the highest.

The disadvantage is that the design and manufacturing accuracy of the original spinning short car is difficult to meet the requirements of installation of collective doffing, thereby reducing its reliability and stability.

The utilization rate of the spinning downer is low, and each spinning frame is equipped with a large area, with high manufacturing cost and high cost.

< /p >

< p > the essence of the intelligent falling car is the three-dimensional robot, which is an intelligent doffer car with automatic control of electromagnetic induction, light, electricity, gas and whole process.

Through photoelectric and displacement sensor detection signal to accurately locate mechanical action, after PLC processing, servo motor and pneumatic components are controlled, and the whole process automation of car movement, full tube, plug pipe and full pipe collection is achieved. It is an independent invention under unique conditions in China.

The utility model has the advantages of ingenious structure and high automation, and can remove the bobbin without damaging the yarn, so that the spinning machine with large number of ordinary spindles can realize automatic doffing.

< /p >

< p > compared with foreign countries, the current domestic < a href= "//www.sjfzxm.com/news/" > intelligent doffing vehicle < /a > has the following innovations: it can adapt to the falling of spindle and aluminum ingots; the tube drawing is simulated by manual rubbing, so that the bobbin is detached from the spindle in advance, and the spindle and bobbin are not damaged; the high-performance flying shear and the space arc interpolation control algorithm technology are applied; the highly reliable right angle three coordinate linear motion robot technology is applied; the multifunctional airbag type grasping mechanism is designed; and the efficient rotating tail yarn technology is designed.

< /p >

< p > I think that the automatic doffing device complies with and solves the current predicament of high labor cost and high labor cost, and realizes the function of machine safety work without catching fire, grasping the pipe without damaging the yarn and pulling the tube without damaging the ingots.

< /p >

< p > intelligent landing car can easily realize the pformation of the old machine, do not need special pformation of spindles and bobbins, and can be used in conjunction with any old and new ring spinning frames, and can adapt to the doffing of spindles and aluminum ingots.

The pformation of the collective doffing device of the spinning short car has saved the doffing workers compared with the intelligent falling car, but it has increased the maintenance workload and the expensive material cost.

The main cost of intelligent falling car is in grasping air bags and scissors and electronic components.

< /p >

< p > < a href= "//www.sjfzxm.com" > spinning short car < /a > the head dropping rate of the collective doffing device is relatively high, but if the spindle tail yarn is not cleaned in time, the retention rate will drop sharply.

The S9 intelligent doffer manufactured by Tongling song Bao Machinery Co., Ltd. has a unique method of retaining head, its hardware design and software support are well matched, and the tail yarns do not need special cleaning. The retention rate is better than that of artificial doffing.

< /p >

< p > enterprises that need to pform doffing devices should pay attention to analyzing whether they have the conditions for pformation and which kind of doffing form is more suitable for their own pformation.

The more high-tech and intelligent devices are, the more attention must be paid to reliability and stability.

In production, if there is a doffing equipment failure, it will cause the overall production rhythm disorder, so that enterprises can not afford it.

Therefore, many spinning mills also want to go to the intelligent doffer, but most of them wait and see.

Many enterprises worry that their management and technology can not keep up with them, but they are rather self defeating.

As a matter of fact, the use time of intelligent car is not long. Some enterprises are also reflecting the instability of electrical and mechanical devices.

< /p >

< p > intelligent doffing car is a pitional product which is less than a href= "//www.sjfzxm.com" > spinning automation < /a > production process. It can be used in conjunction with all kinds of ring spinning frames. It is in line with the requirements of China's textile industry upgrading and technological pformation, and has independent innovation, and has good prospects for popularization.

The digital control system is set up for the collective doffing equipment of spinning long cars, and the real-time monitoring of the change of spinning tension can be realized by optimizing the spinning tension curve, reasonably controlling the < a href= "//www.sjfzxm.com" > spinning < /a > speed and achieving the best production efficiency.
