CISMA2015 takes "intelligent sewing solution" as its theme, showing that the world's sewing equipment product technology development has entered a big era in which a new type of sewing equipment products supported by information technology is the main trend. Whether it is a single sewing equipment or multiple combined sewing equipment at the exhibition, the automatic control sewing equipment products supported by information technology have accounted for more than 50% of the exhibits. The new type of sewing equipment integrated with information technology and industrialization has become the main direction of the development of industrial technology. The transformation of traditional sewing equipment with information technology has become the general trend of transformation and upgrading of the entire industry. The sewing equipment supported by information technology has been Becoming a large market supporting the development of the world's industries, and also providing the basic conditions for the exhibition theme "Intelligent Sewing Solutions".

 Product control technology of quilting equipment has gone through a long development process. The traditional sewing machine product control technology mainly adopts mechanical control methods. For example, lock stitch sewing machine, the four main mechanisms of the main axis of the machine, such as stabbing, thread hooking, thread picking, and feeding, send motion information to realize the four major mechanisms. The coordination and synchronization of the movements of the actuators--puncturer (needle), thread hook (shuttle), thread take-up (thread take-up lever), and feeder (feeding tooth), can ensure the formation of stable stitches, Seam. On the main shaft of the lock stitch sewing machine, a needle bar crank that sends a motion signal to the stabbing needle (machine needle), a bevel gear or a synchronous belt gear that sends a motion signal to the thread hook (shuttle), and a thread picker ( A thread take-up crank that sends a motion signal, and a feeding eccentric and a tooth lifting eccentric that send a motion signal to the feeder (feeding tooth). They are transmitted by their respective mechanical transmission mechanisms to realize the movement time of different actuators such as the needle feeder (needle), thread hook (shuttle), thread take-up (thread take-up lever), feeder (feeding tooth), etc. Coordination and synchronization requirements of motion trajectory and amount of motion. Although these signals are transmitted and processed by analog signals, such mechanical control technology has continued in the sewing machine product technology for more than 160 years, and its reliability and stability have long been appreciated by the world. However, since the control signal generation sources of the machine are concentrated on the spindle, and all signal sources are not editable. Therefore, the use function of the product is single seam (especially in special machines such as bar knitting machines, buttonhole machines, staplers, etc.) and rigid.

 Automatically controlled sewing equipment products supported by information technology are products that use digital signals instead of analog signals, digitize analog signals, and use computer digital processing technology to digitally transmit and process the working process information of sewing equipment. Since the control signal generation source of the sewing equipment is a digital signal issued by the computer controller according to a set program, not only can the various actions of the machine, the coordination and synchronization of motion control, but also the set program can be re-programmed. Editing, this can expand the scope of use of the machine and become a flexible and adaptable automatic control sewing equipment.

 The working process of new sewing equipment products supported by information technology is generally the process information of sewing equipment work. Information is obtained through information acquisition devices and processed digitally. Then, relying on powerful computer digital processing technology, information on the working process of sewing equipment is provided. Information processing is performed in accordance with the edited program (the program is editable), and then various execution information commands are output according to the program, and then the information execution agency (device) executes the information commands, so that each execution agency (device) of the sewing equipment working process ) Executing actions can perform coordinated and synchronized work in accordance with prescribed procedures to achieve the requirements of automatic control of the working process of the sewing equipment.

 The development status and trends are briefly described as follows:

 Information-based motion control technology:

 Information-based motion control technology, which is mainly a product technology that uses information-based technology and an execution mechanism or device to automatically complete a predetermined motion requirement instead of manual motion.

 The products using information-based motion control technology displayed at this exhibition mainly include: sewing machine adopts information-based motion control technology to realize the technology of automatic control during the preparation of sewing, during the sewing process, and after the sewing operation. The motion control technology has been very stable, the control functions are becoming more and more powerful, and the control objects are becoming more and more abundant. Includes motion control functions such as automatic needle stop, automatic thread trimming, and automatic thread setting after sewing developed in the early stages, motion control functions such as automatic presser foot lift and automatic surface stitching developed in the later stages, and automatic reverse stitching and automatic Needle counting (automatic reinforcement), automatic thread break alarm, automatic lower thread remaining amount detection, automatic shuttle change and other motion control functions, automatic needle stop position before sewing, automatic presser foot lift, automatic seam start and other motion control functions have been expanded. The ability of automatic control improves the level of information technology of the sewing machine. It is widely used on large-area wide-stitch sewing machines, overlock sewing machines, interlock sewing machines or special sewing machines. Whether it is Duke Pu Aihua, Pak Fook of international Europe, Japanese brothers, heavy machinery, Pegasus, Yamato and other famous companies, or China's standard, Shangong, Jiejie, Jack, Hailing, American aircraft and other famous companies, or The unknown new companies have launched their own sewing machine products with information-based motion control technology. The popularity and maturity of information-based motion control technology can be seen in general.
