The application that sewing machine centers in Electromechanical fluid to enrage unifinication mostly in light of its development, do not have oil or small oil-lubricated of the system use, application of design of formative of industry of the application of electromotor of straight drive type, application of means of computer much programme controll, individuation is waited a moment, these all promote the development of sewing machine supreme summit. For mechanical to our country sew manufacturer, already much home pushs out to use bag of machine, send side of makings sewing machine, single shot integratedly to cut without corner of sewing machine of oily straight drive, double needle smooth seam machine, electronic-controlled high speed covers knot machine, Xiaofang head series stretchs tight seam machine etc, realized sewing machine to span newly.
Take industrial sewing machine for, sort of industrial sewing machine is various, if make the same score,seam machine, whipstitch machine, high speed to stretch tight seam machine, electron to cover knot machine and high speed to be seamed zigzag machine etc, the athletic character of these sewing machine and torsion contrail have different characteristic each. Master these sewing machine to run the character of orbit, use advanced closed-loop control technology, can control the output torsion of electric machinery and rotate speed accurately, make work according to appropriate moving contrail. This project development makes the same score the intelligent controller that seams servo of aircraft electric machinery in the light of high speed. This controller is achievable a variety of sew mode, prefab litre fall fast time, implementation cuts a line automatically, batch answer line, automatically seam, the process designing control of the craft parameter such as pin number choice, implementation high speed is smooth at the same time seam the fast fixed position with high-powered machine.
Technical characteristic reachs applied domain: This project basically is the feature with unique system of the transmission in be aimed at industrial sewing machine, studying the athletic character of all sorts of industry sewing machine and torsion contrail, communicate asynchronous electric machinery and dc to go up without the foundation that brushs characteristic of electric machinery servo, emphasize research to apply to high speed to make the same score seam the intelligent controller of machine. The technology of this intelligence controller is same applicably the development of the controller at sewing machine of other type industry. This controller will own own intellectual property, achieve international advanced level, replac existing entrance product.
Applied foreground and market forecast: Current and general the price of equipment of a complete set of of sewing machine of industry of a high end is 5000 yuan of RMBs, but among them controller counts an import, need to cost 3000 yuan of RMBs. The intelligent control equipment that development has own property right appears particularly pressing and important. Realize high speed to make the same score especially seam machine is high-powered what decide position control system quickly is homebred change, replac an entrance, raise performance/price ratio, enhance product international competition ability, have broad market perspective.
The development of sewing machine depends on intelligent sew, all measure domestic and internationally now in concentrated force, undertake seamability the development of compositive environment system. Seamability is compositive environmental system interrelates by 3 received online system composition, can seam a gender to forecast a system, intelligent sew system reachs safe character system, the purpose depends on making product quality is standardized, through removing the sew issue that clothing fabrics brings, improve manufacturing efficiency, reduce the skill demand that handles personnel thereby.
Seamability is compositive the mechanical property that environmental system leaves according to the low stress of clothing fabrics (drawing cuts function, curve function, ply to reach compress function) , pass sensor and parameter of driver setting sew, the sew that forecasts clothing fabrics is injured and corrugate seriousness is opposite juncture fabric is arranged offer reasonable proposal, make fabrics gets used to the sew of high quality.
In intelligent sew system, sewing machine can pass sensor and parameter of driver setting sew automatically, with optimizing sew quality is mixed improve manufacturing efficiency, reduce the skill demand that handles personnel. Sew still is set to injure system and laser danger to measure juncture on sewing machine at present corrugate system; The penetration that sew injures a system to measure machine needle in order to detect the injury of sew process; Laser detects juncture is corrugate what the system measures edge sewing thread is corrugate be out of shape with ensuring sew seams quality character, when these parameter satisfy a requirement, artificial intelligence technology optimizes those who finish pair of sew parameter the setting, include to approach mark of tension of crural pressure, sewing thread, line density and number of sewing thread name. This is the development of prospective sewing machine.
