Songbao Intelligent Doffer: Battle for Workers

From the ITMA ASIA+CITME 2010 exhibition, it was first released to the 2011 Shanghai Textile Industry Exhibition for the first time. The first two prototypes from well-known companies such as Wuxi First Cotton, Shandong Liaocheng China Resources and Xuzhou Tianhong to Anhui Huamao took the lead in completing the first five. Million ingot transformation; from the beginning of research and development from 5-6 years ago to the beginning of August this year, China Academy of Textile Machinery Association and China Cotton Textile Industry Association organization, Chinese Academy of Engineering Yao Mu led the appraisal meeting, Tongling Songbao Machinery Co., Ltd. independently developed The S9 type ring spinning intelligent doffer has finally been recognized and praised by people in the industry in less than two years.

At the end of September, a “Song Bao Cup” national spinning equipment technology seminar was held in Hefei with the main purpose of promoting the S9 type ring spinning intelligent doffer. More than 200 representatives of textile companies from home and abroad came with the expectation of the S9 ring spinning intelligent doffer. The introduction of the S9 ring spinning intelligent doffer brings the possibility of replacing the artificial doffing by mechanization, reducing labor and improving production efficiency. This ring spinning intelligent doffer from Tongling Songbao Company has brought about a better solution to the “labor shortage” caused by the high labor costs that textile companies have to solve in recent years.

Solving the three major problems As early as five years ago, Tongling Songbao Machinery Co., Ltd. began to research and develop the S9 type ring spinning intelligent doffer for the current tedious doffing work. Since then, the company has hired top experts in the field of mechanical automation and materials from Tsinghua University, Donghua University, etc., and has established a number of electrical suppliers with high automation levels, such as Siemens, B&R, Schneider, etc. at home and abroad. Long-term cooperation.

S9 type ring spinning intelligent doffer adopts advanced programmable automation controller (PAC) electrical control system and AC servo motor drive control system. The mechanical grabber adopts three-dimensional rectangular coordinate robot control platform technology to realize the extubation , intubation, return to the full automation.

In general, the S9-type ring spinning intelligent doffer solves three major problems: one is to facilitate the transformation of old machines without changing spindles and bobbins; the other is to serve multiple doffs and to make maximum use of doffing. Machine use efficiency; third is to completely replace the manual pull, plug doffing links, reducing the labor intensity of the doffing workers.

According to reports, the aircraft has features such as easy operation, flexible use and low cost. The two doffers are a group, which can be doffed on the left and right at the same time and can serve multiple spinning machines of different types. This machine can completely replace the traditional manual pulling and inserting tube work and basically realizes the entire doffing process. Automation. The key technology of this machine adopts a completely independent and innovative pipe-pulling structure, which realizes the purpose of quickly and continuously unwinding the bobbin yarn, without any damage to the accuracy of the spindle, and automatically doffing the light spindle bar spindle. It overcomes the problem that automatic doffing at home and abroad can only adapt to aluminum casing spindles. This technology has filled the blanks at home and abroad, leading domestic technology. At the same time, the aircraft has applied for a total of 22 patents, including 5 invention patents, and has authorized 2 invention patents.

More economical and practical At present, Anhui Huamao Textile Co., Ltd., Shandong Liaocheng China Resources Textile Co., Ltd., Tianhong (China) Investment Co., Ltd., and Wuxi No.1 Cotton Textile Factory are a number of domestic first-class textile companies are S9 ring spinning The main use of intelligent doffers. From 2010 Huamao Anhui began to try this product, so far, the company has cumulatively used eight S9 ring spinning intelligent doffer, 112 sets of spinning machines, a total of 53,760 spindles. Huamao recently decided to fully promote the use of this equipment within the company. Now, Tongling Songbao Machinery Co., Ltd. is supplying Huamao with a weekly rate of 10 spinners. At the same time, Shandong Liaocheng China Resources Textile Co., Ltd. has also completed the transformation of 30,000 spindles. Wuxi's first cotton textile mill has already transformed 10,000 spindles, and Tianhong (China) Investment Corporation has also completed 20,000 spindles.

It is understood that the first cotton textile factory in Wuxi, Shandong Liaocheng China Resources Textile Co., Ltd. are mainly spinning high yarn, the choice of S9 intelligent doffers to make these companies like fish. Tianhong (China) Investment Co., Ltd. is currently one of the largest spinning and spandex yarn core yarn companies in China. The production of spandex core-spun yarn has the characteristics of high doffing frequency and difficulty in retaining the head. This requires the operator to have high skills to block vehicles. Resolving the automatic doffing of spinning frames has always been a concern for the senior management of the company. After trying all kinds of doffing machines at home and abroad, the company still believes that the Songbao S9 intelligent doffer is the most suitable for them. Production needs.

With the continuous expansion of the use of S9-type ring spinning intelligent doffers, textile manufacturers gradually felt the benefits of this equipment. According to the person in charge of Anhui Huamao Textile Co., Ltd., from the use and comparison of Huamao for more than one year, it can be seen that the S9-type intelligent doffer is a mobile collective doffer, when the company spins 32-40 yarns Only 2 sets of intelligent doffers can easily perform doffing tasks for 28 480-spindle spinning machines, but 11 long-deck collective doffing machines must be completed, and the collective doffing of short cars must also be equipped with 28 units. Taiwan, in contrast, the S9 intelligent doffer costs less investment.

In addition, from the perspective of pulling and inserting the tube, the S9 intelligent doffer is basically the same as the collective doffing device. From the standpoint of retention rate, the head of the collective doffing device is relatively high in the initial stage of tailing yarn cleaning. If the tail yarn of the spindle is not cleaned in time, the head retention rate will drop sharply. The S9-type intelligent doffer has a unique method for retaining the head. The hardware design and the software support are relatively good. The retention rate is relatively stable, and the tail yarn does not need to be specifically cleaned. Overall, it is better to leave the head than artificial doffing. From the perspective of the number of workers, the two types of doffing are almost the same. Although the collective doffing saves the doffing workers, it increases the maintenance workload. For the S9 type intelligent doffing doffing workers, as long as one person is doffed, maintenance does not require additional personnel. From these comparisons, it can be seen that if the spinning machine is currently under automatic doffing retrofit, choosing the Tongling Songbao S9 intelligent doffer should be the best solution.

The market demand is huge In recent years, the country has actively promoted the enterprise industrial upgrading and sustainable development model. The arrival of the "labor shortage" has enabled textile companies to further recognize the urgency of improving the labor environment and increasing production efficiency. The ring spinning doffing link is a place where the textile enterprises are more concentrated in labor. It is particularly urgent to reduce the doffing work and free the doffing workers from the hard work and exhaustion.

It is understood that China currently has more than 100 million spindles for ring-spinning spindles, but the vast majority of these spindles still rely on artificial doffing, and they mainly rely on doffing. Due to the serious damage to the spindle, the doffing of the car has been limited. Although the collective doffing of long vehicles has developed rapidly in recent years, there are also some problems. The original intention of the development of long-range car clusters is to promote the promotion of the network. Due to the constraints of venues and processes, there are not many real manufacturers that currently implement long-haul vehicles. At the same time, since the long-range car clusters are built into the spinning frame, they can only achieve their own goals. Single doffing can not achieve multiple doffs, and the input and output ratio of the collective doffing is obviously asymmetric.

According to the person in charge of Huamao Equipment, a 480-spinning spinning machine with a collective doffing device and a Songbao company's intelligent doffer have a small gap. For example, the equipment for 480 short-wheel dumpers is about 160 yuan/injection, which is only applicable to the doffing of a 480-spinning machine. Although the use of labor is reduced significantly, the cost of post-maintenance and consumables is higher; intelligent doffer equipment Input (according to the number of spinning and the number of machines for doffing) ranging from 50 yuan/ spindle to 90 yuan/ spindle, 2 doffers as a group, doffing range up to 5760 spindles to 21000 spindles, falling Yarn workers can be reduced by half, and the cost of post-maintenance and consumables is low.

In the “Song Bao Cup” national spinning equipment technical seminar 2011, Anhui Huamao introduced the use of the S9 intelligent doffer, and more textile companies started to pay attention to the S9 type ring spinning intelligent doffer. Although Jiangsu Nantong Dasheng Company has not yet officially used the aircraft, the senior management personnel of the company has been paying attention to the market maturity of this machine. According to Zhao Zhihua, assistant to the general manager of the company, after the company's field visits and understanding of Tongling Songbao Machinery Co., Ltd. and Anhui Huamao, it is ready to begin trial operation of the aircraft. Zhejiang Bailong Textile Machinery Co., Ltd., responsible for purchasing, said that the company has been paying attention to the marketization process of the S9-type ring spinning intelligent doffer. Recently, the company has sent relevant persons to visit Songbao Machinery Co., Ltd. in person. It is understood that Shijiazhuang Changshan Co., Ltd., Shandong Dezhou Huayuan Mill and other companies also sent representatives to Anhui Huamao to conduct field visits, and agreed that the Songbao S9 intelligent doffer is better than expected.
