The key technologies of quilting computer control system is the joint control technology to saddletree, roller and hackle.Computerized quilting machine adopts CPU parallel processing technology for computerized quilting machine' s data processing and transmission.And then the previous traditional appropriative Delta mechanical have been inproved a lot; The key technologies of quilting to saddletree control, roller control and spindle control have been solved well. quilting computer control system have realized the production process automation and own the function strong fault tolerance, automatic stop function when thread breaks, the protection of overheating, automatic detection and protection system failure and self-diagnosis capabilities.
On the whole, the design technology of quilting control system with high starting point, better compatibility and strong anti-jamming ability. According to the international practices and the specific requirements of design of the computerized quilting machine ,the design technology of quilting control system have made optimized design.The main features of the technology as follows:
1）In the saddletree and roller system control technology, according to the saddletree or the actual load of roller, the ball screw and the principle of belt drive,the needly-speed of quilting and the track of quilting needle, reasonably choosing saddletree and roller motor-driven, accurately calculating the saddletree and roller acceleration, optimally designing the control curve of the main axis driving command to ensure the quality and output of quilting and improve the overall design level of the saddletree and roller systems.Make use of the stepper motor in stead of the AC servo motor drive to drive the saddletree,so as to improve the the overall performance index of saddletree and roller system.
2) In the main control system technology,according to the actual load of axis, the principle of belt drive, the speed of quilting,the track of quilting needle and many other requestment of parameters, reasonably choosing the motor-driven of spindle and the accelerometer of the main axis, optimally designing the control curve of the main axis driving command to ensure the quality and output of quilting and improve the overall design level of the main axis of technical systems development.
3）In the overall structure of the hardware and systems, according to the system performance and function, optimally designing the system circuitry, carefully designing the system of industrial environment,designing the system performance and working stability and system security and so on. Strictly adopting the way of components control and derating design, reasonably choosing computer chips and components and integrated circuit chips, with the best prices and the highest reliability of the unit to achieve the required functions. Take shielding, thermal design and the right way of wiring in to achieve industrial environment electromagnetic compatibility.
4）In the system control software,for the inherence of software flaws and the complexity of the environmental mistakes, a series of preventive measures are adopted in the software design,and variety of implementation are monitored for putting an end to malfunction by interference when quilting.
