Industry in 2011

100 thousand square meters, more than 1200 exhibitors, take the lead, many viewers seem to feel that this year's exhibition "bright spot" is not much.

But careful observation, it is not difficult to find some products and technology development context.

Embedding digital control technology on mechanical products, simplifying mechanical structure, expanding the function of equipment, realizing man-machine conversation, improving work efficiency, advocating energy saving and environmental protection are the main directions for the development of sewing equipment again.

Digital control is universal.

The computer controlled high-speed sewing machine has a tendency to replace ordinary high speed sewing machine.

For a time, single shear line, two automatic and three automatic everywhere, set off the first round of digital pformation of sewing machinery.

Apart from flat sewing, sewing, sewing, sewing, twists, buttonholes, buttonholes, reinforcement and fancy sewing machines, almost all kinds of new models, such as double needles, rollers, synchronizing, fur, pull, bead, four needles, six lines, splicing, reel feet, multi pin sewing machines and so on, have been equipped with digital control systems. Sewing machines have entered the digitalization and information age in an all-round way.

Wenzhou Hengtai, known for its production of bead sewing machines, develops its own control system on the basis of the HT-8850A multi function twin needle sewing machine. It is programmed on the basis of 100 basic patterns of touch screen and can pform various decorative stitches.

Sewing equipment to achieve digitalization requires technical support.

In recent years, with the maturity and popularization of related technologies, many enterprises have been involved in the research and production of digital control systems, and the output and varieties have doubled and increased, and the cost has been greatly reduced.

A brand name has long been a history. Bo Max, Qi Xing electronics, Hangzhou exciter (China Light Industry Automation Research Institute), Wolong electric company, Ningbo Sheng Sheng, Zhongke Derun (Zhejiang Kansai) and other "Princes" rely on their professional advantages to compete with each other, while silver stars, Noda, Fang De, Phaeton, cocoa and so on rely on the blood relationship with the whole production enterprise to become bigger and stronger.

In the field of special machine control system, Sichuan's Saint Wei, Shenzhen, and other enterprises have opened up a new path to compete with foreign brands in the high-end field.

In addition to the embroidery machine control system, the big industrial sewing machine servo electronic control system was unveiled in the exhibition for the first time in an independent stand, displaying the control system of reinforcement, pattern, round head lock and flat nose keyhole machine, conveying the determination of Beijing Xing Da Hao to enter the field of special sewing machine control system in a high-profile manner.

The participation of some small and medium-sized private enterprises in Taizhou has added more vitality to the competition of CNC system products.

As close to the whole machine manufacturing enterprise, research and development mechanism is flexible, leading local large number of small and medium enterprises, especially the special sewing machine production enterprises joined the ranks of digital upgrading.

Although the production is the first of the same products in China, the company with less than 100 people is hard to get the favor of the control system manufacturers, and it is even impossible for them to jointly develop the scientific research institutes or universities.

With the help of geopolitical advantages, Jia Jing Yi car and Hong Yue electromechanical cooperation have custom-made the ultra-thin direct drive servo motor and control system for fur sewing machine, which not only keep the shape characteristic of the machine, but also satisfy the use function. The computer controlled direct drive fur machine and puller product have filled the gap in China.

Change "sewing machine" to "sewing unit".

The so-called "sewing unit", defined by the international organization for standardization ISO, is: "at least one sewing machine, sewing machine platen and rack and sewing machine driver equipment.

Sewing machines and sewing units should generally be equipped and / or connected to one or more units (e.g. sewing, tangent, feeding, etc.).

Sewing materials and sewing machines themselves are controlled manually or automatically. "

The AC-172N-1790SA1K high-speed electronic keyhole automatic delivery machine (Figure 1) displayed by heavy machinery company is a typical two development process from "sewing machine" to "sewing unit".

On the basis of the mature technology of type 1790 high-speed electronic keyhole machine, the device for clamping, absorbing, feeding and receiving has been added. In the original control system, various functions have been expanded, so that the feeding device can keep synchronous with the feeding mechanism of the keyhole machine when the sewing device is locked, and when the keyhole is completed, the garment piece can be pported to the starting position of the next button hole independently.

The number of button holes, starting position, edge spacing, buttonhole spacing and other parameters can be conveniently set through the operation interface of the display screen, so that the keyhole sewing of a plurality of button holes on the upper garment piece can be completed at one time and the position is precise.

The sewing unit is programmed with digital control technology, man-machine dialogue interface, special automatic feeding, receiving and positioning auxiliary device. Some sewing machine models are built into special equipment that can be applied to different garment manufacturing processes. Different processing parameters and specifications in the same process are realized through the setting of the operating system.

The "sewing unit" greatly improves the work efficiency and sewing quality, reduces the dependence on sewing workers' technical level and proficiency, and achieves the consistency of garment batch processing.

Domestic enterprises in the "sewing unit" research and development is also gratifying, some backbone enterprises rely on their own advantages in the "sewing machine" varieties and quality advantages, as well as mechanical, electronic, automation control and other aspects of talent, to create high-end garment production enterprises need "sewing unit".

The standard share TC764 programmable automatic pocket sewing machine is a special stitching device for jeans and shirt bags based on the GC6720 single needle sewing machine. It adopts large capacity rotary shuttles and automatic thread cutting device, plus laser positioning, automatic folding, automatic feeding and automatic stacking device. It can be programmed according to the shape of different pockets, and can guarantee the processing capacity of 1100 pants (2200 pockets) every 8 hours.

The new Jack JK-T5878-58 series automatic button machine is also made use of the computer direct drive sewing machine head. It adopts unique head movement structure, adds laser positioning device, independently adjustable middle knife device and automatic receiving device, and can complete the sewing and cutting of T-shirt Lapel at one time.

Through the editing and storage functions of processing programs, the sewing of all kinds of male and female T-shirts can be made, and the output is as high as 2400~2800 pieces per 8 hours.

By upgrading the twin needle sewing machine, reinforcing sewing machine, sewing machine and sewing machine, a number of sewing machines, such as bag machine, nail pants loop machine, trouser loop sewing machine, waist waist waist machine and rubber band knitting machine, are no longer just samples and exhibits of deep boudoir, and have been gradually developed into mass production.

Expanding functions to enhance added value

It is also an important way to redevelop the products on the basis of the original ones.

Zhejiang Hongli has always adhered to the "knitting sewing equipment" as the development direction. It has carried out comprehensive upgrading of motor direct drive, pneumatic cutter, automatic thread cutting, automatic waste suction and seam sensing control on the common sewing machine and sewing machine products, and formed series of products of different specifications, different functions and grades, so as to meet the needs of different users and form their own distinctive characteristics.

The CLK-1905D electronic pattern sewing machine is a medium pressure foot separation mechanism which has applied for national invention patent on the electronic reinforcing machine. It achieves the function of both the reinforcing machine and the pattern machine, and it can meet the requirements of different fabrics and different sewing processes.

Ningbo schapp is a rising star in the industry, sticking to the idea that technology makes you more relaxed.

At this exhibition, the company shows two series of derivative products, such as pneumatic drilling and sewing machine, trousers and trousers machine, rubber band knitting machine, nail fastening machine, automatic nail loop machine and so on.

The function of the product is excavated, and the general model is expanded to the special equipment for each garment process.

After the two development of the nail loop machine and the rubber band machine, equipped with automatic positioning, automatic conveying and automatic charging devices, and further digitalized upgrading, the sewing unit with high technology content, such as automatic nail loop and automatic rubber band, has been formed.

This phased product redevelopment idea has small investment, short cycle and quick results. On the basis of consolidating the existing research results, it keeps innovating, "accumulating small gains to win the great victory", with constant gains.

Singing the theme of energy saving and environmental protection

The popularization of servo motor and no (micro) oil direct drive technology on sewing equipment, in addition to simplifying the mechanical structure, expanding the function of the equipment, enhancing the added value of the products and improving the work efficiency, is more in line with the basic national policy advocated by the government to build a resource-saving and environment-friendly society and to take the road of sustainable development.

Compared with the traditional clutch motor and electronic motor, the servo motor driven high-speed sewing machine can save at least 1 kwh per hour (8 hours per day). According to 250 working days per year, it can save energy consumption by at least 250 kwh per year.

If we produce and put on the market 800 thousand computer high-speed sewing machines every year, we can save 200 million kwh of energy and 72 thousand tons of standard coal. The economic and social benefits are very significant.

In May 2011, the China Quality Certification Center (CQC) put the computer controlled high-speed sewing machine in the scope of national energy conservation and environmental protection certification.

In September of this year, GC6730MD3 and other six products of standard stock became the first batch of energy saving and environmental protection products certified by CQC through the certification of energy conservation and environmental protection.

During the exhibition, the issuing ceremony of energy saving and environmental protection product certification was held in Shanghai, which perfectly explained the theme of CISMA2011's "quality and efficiency green".

Many people in the industry show great enthusiasm for energy saving and environmental protection certification. The products of Zhejiang MAQI, Ningbo three, Zhejiang Duma and other enterprises have passed the sample inspection of the certified products and entered the factory inspection stage. The certification application of new refinement, new Jack, gemstone, Shun Fa and Sichuan Tian has also been accepted by CQC; more enterprises are actively consulting, preparing and applying.

In the near future, like refrigerators, air conditioners, washing machines, there will be more sewing equipment products with energy-saving or energy saving environmental protection certification marks, which will greatly enhance the overall image of the industry and enterprises.

Miniaturization and integration

At CISMA2004, the computer high-speed sewing machine is mainly based on the plug-in type machine, and the motor drive mode is popular in the industry. However, the control system still plays the role of supporting parts. It does not really integrate with the sewing machine. The packaging and installation of the field, the exposed power and the model connection line to a certain extent affect the integrity and appearance of the product, and also bring some inconvenience to the installation of the user. "CISMA2005"

At this exhibition, the integrated integrated computer sewing machine was unveiled. The brand of gem, Hui Bao and Sen Sen adopted the technology of Zhongke Derun (Zhejiang Kansai), integrated the controller with the sewing machine head, broke the traditional mode of separating servo controller from encoder, realized the integration of motor, encoder and controller, and embodied the integrated design concept in structure, installation and software function.

The integrated integrated product makes up for the deficiency of the split form, reduces or shortens the connection line, improves the stability and anti-interference ability of the system, and has the characteristics of compact structure, small volume, and user "zero" installation.

Shanghai Toyama H9180N-7 uses backside design to integrate control boxes into the back of the sewing machine, increasing the heat dissipation area.

Taizhou Xingyi and other enterprises also adopted the back type integrated design.

The integrated technology of electric control box and oil pan invented by Chung Chung heavy industries greatly eliminated the influence of mechanical vibration on electrical components after integration and integration, and improved the reliability of products.

The computer controlled sewing machine is integrated from motor external drive, motor direct drive to control system, and develops towards miniaturization and integration. It achieves plug and play and integrates mechanical part with control part.

Unwilling to be lonely parts manufacturers

Sewing equipment goes to digitalization and information age, and spare parts manufacturers can not help.

Direct drive no (micro) oil sewing machinery puts forward higher requirements for parts and materials and surface treatment. Parts must be equipped with super high hardness, super wear resistance, low friction coefficient, excellent corrosion resistance and oxidation resistance.

Nanfeng vacuum coating (Shanghai) Co., Ltd. adopts the latest patent technology of "filtered cathodic vacuum arc plating technology" (FCVA). The diamond coated Tac coating on the metal surface has super high surface hardness, low friction coefficient, and can adapt to the high-speed friction motion in oil-free state.

This provides the best solution for oil-free or high-speed, ultra high speed machine parts with large friction area, high speed or continuous lubrication.

The standard shares of six direct drive micro oil products, such as GC6730MD3 and other energy-saving and environmental certified products, all use diamond-like coated needle rods coated with vacuum coating by Nash company.

The domestic computerized sewing machine is not ideal in silk and light sewing. Users complain more closely.

Ningbo Yong Yao has made great efforts to achieve the sewing effect of the computer sewing machine's polyester thread (silk ray) with the "five characteristics, five patents" and the special sewing machine for sewing machine sewing machine.

In addition to the digital control system for sewing equipment, servo energy saving motors, which take the place of traditional clutch motors as targets and have remarkable energy conservation effect, also have wide market.

Zhejiang's Shanghai dragon, Chung bang, billion won, accumulation, founder motors, rainbow and other enterprises have increased investment to produce all kinds of servo energy saving motors, providing a digital control power system for ordinary sewing machines.

Zhejiang Shanghai Dragon exhibition has introduced two new intelligent speed governing permanent magnet DC motors with needle stop function and sewing permanent magnet synchronous servo controller.

The intelligent speed regulating permanent magnet DC motor has the stepless speed regulation function of 500~3000 turns per minute, which can be applied to sewing machines of different kinds of machines, saving more than 60% of the clutch motor.

Its "stop needle positioning" function can also stop the needle or stop the needle according to the needs of users.

Electromagnet, wire cutting device, embroidery machine gold strip, rope conveyor, stepper motor, many spare parts manufacturers continue to introduce upgrading products to provide basic support for digitalization and information upgrading of sewing equipment.

Long way to go

In October 5, 2011, Steve Jobs, one of the Apple Corp's founders and former CEO, died. President Obama praised it as "one of the greatest innovators in the United States".

Under his leadership, apple went beyond ExxonMobil to become the world's largest market maker.

Careful study is not difficult to find that many of its products are redeveloping the functions of traditional products, integrating and integrating all kinds of mature technologies.

"Mechanization" and "information", information instructions need execution agencies to complete, "mechanization" is the foundation.

China Sewing Machinery Association is organizing the implementation of product quality improvement activities, sewing equipment sewing performance, machine performance, operation performance, matching accuracy, clearance wear as an important research project, with 500 hours of simulation test to test the reliability of the product.

It is rare for domestic manufacturers to establish internal reliability test mechanism. The early failure rate of mechanical components is high, and the mean time between failures (MTBF) is short.

If the mechanical parts are deficient, the "old cucumber" will not work.

How can we paint beautiful "green lacquer" on "old cucumber" to perfect the integration of digital control system, information system and executing agency?

Strong technical support is needed, including talent pool, capital investment and team spirit, but also can not be separated from the whole industry to optimize resources and cooperate with each other.

Jobs said well: "the difference between leaders and followers is innovation."

Only by constantly introducing innovative products to lead the market can we maintain the competitiveness and vitality of enterprises.

After 20 years of rapid development, the sewing equipment industry in China has made remarkable achievements, but it still has a long way to go.
