< p > 2001, the F1520 type collective doffing spinning frame car was developed and opened the era of China's a href= "http://www.91se91.com/news/index_c.asp" spinning frame < /a >.

< /p >

< p > annual gross ingots decrease, labor expenditure about 300000 yuan < /p >

< p > Jingwei Textile Machinery Limited by Share Ltd Yuci branch is the first company to develop collective doffing long cars in China. As early as the late 90s of last century, F1518 was first developed and produced.

The collective doffing system draws on the advantages of TOYOTA and Johnson's collective doffing device. However, due to China's basic industry, it did not promote much in the early years.

In 2001, the company developed the F1520 collective doffing spinning machine, which opened the era of China's centering spinning machine.

After 10 years of improvement and improvement, the collective doffing device of F1520 spinning frame tends to be mature and stable.

In October 2004, the company successfully developed the F1530 type collective doffing spinning machine with compact spinning. In 2011, a new generation of JWF1562 series doffing spinning machine was developed.

Jingwei Yuci company now has more than 6000 sets of equipment annually, of which more than 2000 are produced by collective doffing and long spinning.

< /p >

< p > compared with the traditional models, the JWF1562 series has made a revolutionary pformation and upgrading to the collective < a href= "http://www.91se91.com/news/" > doffing equipment < /a >.

This series of equipment uses a high sensitive and middle inertia servo motor to drive the new reduction gearbox, which drives the new screw driver to realize the lifting of the gas frame, the general use of the left and right screw rods, and the installation is simple and quick. With the new gas holder components, the herringbone arm is pushed to pull to solve the problem that the air frame is out of shape due to the bending of the putter; the whole short arm is used to directly mount the swing arm seat on the middle wall panel through the pin hole location; and the new air frame swing mechanism is adopted to operate more stable and reliable.

The herringbone arm of the JWF1562 series equipment has no gap connection. The front head personal arm support seat adopts the open type, solves the problem of miter arm slippage, avoids the gas frame hanging, and the gas holder pressure pipe is uniform, even if it is used for a long time, it will not deform; the convex disk pport guide rail is directly installed on the middle wall panel, and the pin is positioned, and the new type of supporting jaw is used to ensure that each claw can work normally, and the dislocation of the pallet can be completely avoided.

At present, the collective doffing rate of JWF1562 series collective doffing is more than 99.5%, the rate of intubation of collective doffing is 100%, and the retention rate of spinning machine after collective doffing is greater than 97% (spinning yarn) and the collective doffing time is 3.5 minutes.

< /p >

< p > production shows that the average number of users in the long distance car business is 1.5, compared with that of the short vehicle, which can reduce labor cost by about 300000 yuan per year, and greatly reduce the labor intensity of doffing workers.

The collective doffing long vehicle also shortened the doffing time, had a relatively high retention rate, reduced the broken ends, and thus increased the labor productivity; using long cars could reduce the floor area and reduce the investment cost (the plant investment can be reduced by 20%); the use of long cars can also effectively reduce the difference between < a href= "http://www.91se91.com/news/" > yarn machine < /a > the difference between the stations, and improve the yarn quality.

< p > the development of the collective doffing spinning machine has been started since the 90s of last century.

< /p >

< p > can reduce the number of workers 40%~50% < /p >

< p > Shanghai two spinning machine Limited by Share Ltd collective doffing spinning machine research and development work has been started since the 90s of last century.

In the first 10 years, due to the technical research and accumulation of the collective doffing device at the initial stage, the stability and reliability of the collective doffing device were not satisfactory due to the restriction of the technical scheme, motor control and electromechanical matching. The equipment was only run in the laboratory and exhibition, and could not enter the normal operation and use of the textile mill.

Until 2004, the company made two rounds of development of the collective doffing device, reassessed the technical scheme, and redeveloped the collective doffing spinning machine with the cooperation of the user manufacturers.

Since then, the collective doffing spinning machine has been formally put into mass production and has been put into use by user factories.

At present, the collective doffing spinning machine has become the normal and mass product of the company, and has gradually become the leading product of the company, and exported to many countries at the same time.

< /p >

< p > the standard index of collective doffing and intubation rate of collective doffing is 99.5%, and the company's internal control standard index is 100%; the industry standard index of driving leaving rate is 96%, and the company's internal control standard is 98%.

The doffing time of the collective doffing device is 3 minutes, and the yarn delivery time is 45 minutes.

Compared with ordinary spinning frame, the use of collective doffing spinning machine can reduce the number of workers using 40%~50%, and at the same time can greatly reduce the labor intensity of operators. Therefore, the use of collective doffing spinning machine is of great benefit to reducing staff and increasing efficiency and improving the working conditions of workers.

< /p >

< p > the spinning equipment of Shanghai two spinning machine Limited by Share Ltd has achieved the automation of single machine. The next step will be to realize the combined unit, namely roving frame, spinning frame and winding machine, to realize automation between spinning processes.

< /p >

< p > the collective doffing device of spinning frame provides equipment for the operation automation of textile industry, and contributes to the reduction of personnel and efficiency.

However, there are still a large number of spinning machines without collective doffing in the industry to be upgraded automatically, and further exploration and practice are needed in order to find out a suitable plan.

The new spinning frame with doffing and the realization of coarse, fine and connection are the trend of automation development of < a href= "http://www.91se91.com/news/" > spinning equipment < /a >. Exploring the intellectualization of spinning equipment is another development direction of spinning frame development.

< p > the main product of the ring spinning intelligent doffer was born in 2009. The doffing rate of this machine is 100% and the accuracy of intubation is 98%.

< /p >

< p > < strong > reduce the cost of maintenance of workers < /strong > < /p >

Less than p years ago, Tongling song Bao Machinery Co., Ltd. and Tsinghua University, HeFei University of Technology and many other domestic scientific research institutions and enterprises began to develop S9 type ring spinning intelligent doffer.

The ring spinning intelligent doffer was born in 2009.

< /p >

< p > the machine adopts advanced programmable automatic motion controller (PAC) electric control system and AC servo motor drive control system, and the mechanical grabber adopts three-dimensional Cartesian coordinate robot control platform technology to realize the whole automation of extubation, intubation and return.

Generally speaking, the machine has basically solved three major problems: first, it is convenient for the old machine to be reformed without changing the spindle and bobbin; the two is to serve multiple doffing, making maximum use of the doffer efficiency; three, it completely takes the place of manual pulling and inserting doffing, and reduces the labor intensity of doffing workers.

The development of the machine successfully subverted the problem that automatic doffing can only adapt to the aluminum sleeve spindle at home and abroad, and this technology has filled the gap at home and abroad.

At present, the machine has applied for 28 patents, including 9 invention patents and 4 authorized inventions.

< /p >

< p > the machine has greatly improved the production efficiency while greatly improving the retention rate of yarn and the yarn damage.

The doffing rate of the doffer reaches 100%, the accuracy of intubation is 98%, the retention rate of driving is 97%, and the doffing requires less than a href= "http://www.91se91.com/news/" > doffing employment < /a > less than 2/3, and the doffing quality is far better than manual doffing.

According to industry experts, a spinning machine with 480 spindles and a collective doffing device are quite different from the intelligent doffer of song Bao company.

For example, the equipment of the 480 spindle short car collective doffing device has invested about 160 yuan / ingots, which is only applicable to the doffing of a 480 spindle spinning machine. Although the employment is reduced obviously, the maintenance and consumables cost is higher at the later stage. S9 type intelligent a href= "http://www.91se91.com/news/" > doffer > /a > equipment input (according to the number of spinning parts and the number of doffer bearing machines) is about 50 yuan / ingot ~75 yuan / ingot, 2 doffer is a set, the doffing range can reach 5760 ingot ~21000 ingots, the doffing employment can reduce the number of 1/2, and the later maintenance and consumables cost is low.

< p > 10000 yuan spinning doffing can save 12~14 people less than /p.

< p > HX-L78 intelligent doffing trolley is a new generation of intelligent doffing trolley which can replace artificial intelligence developed by Shaanxi Hengxin precision textile machinery Co., Ltd. according to market development needs, widely absorbing advanced technology in related fields at home and abroad, and using new design concept, high starting point and high standard.

The HX-L78 intelligent doffing car developed by Hengxin precision spinning machine weighs 180 kilograms, its retention rate is more than 95%, the breakage rate of start-up is less than 5%, the extubation rate and the intubation rate are all greater than 99.5%, and it is estimated that 12~14 yuan can be saved for the labor of doffing doffing.

< /p >

Ma Yan, deputy general manager of the company, believes that with the increasing demand for high quality < a href= "http://www.91se91.com/news/" > textile > /a >, the competition among spinning enterprises is becoming increasingly fierce. The enterprises that spin high-end products gradually increase, and the requirements for equipment are also improving.

In order to reduce the effect of touch, friction and collision on yarn defects and hairiness caused by touching, rubbing and collision during semi-finished products operation and process delivery, the automatic doffing system is becoming the trend of development in the coming years.

At present, several foreign companies producing roving machines have developed automatic doffing systems and automatic pportation lines, including the technology of coarse and fine connection. Domestic enterprises are also developing their own models.

With the increase of labor cost, the automatic spinning machine with automatic doffing has already had certain demand in the market. This is also the inevitable trend of the future development, and will be widely applied by spinning enterprises in the near future.

He also said that because of the large market space of the existing old equipment spinning frame, there are not many enterprises that can really do so. Therefore, Shaanxi Hengxin should speed up the development and improvement of the intelligent doffer car, and seize the market opportunity to contribute to the intelligent and automatic spinning of our spinning frame.
