[System overview] Computer quilting machine, as a new machine integrating automatic control and mass storage technology, has a very wide range of applications in the processing of mattresses, fabrics, bedspreads and other products. At present, quilting machines are mostly divided into computer shuttleless multi-needle quilting machines, computers have shuttleless multi-needle quilting machines, computer High-speed shuttle core winding machines and other specifications. Compared with the traditional mechanical quilting machine, it breaks through its simple pattern function of only half coordinates. Under the powerful computer control system, it can accurately process all kinds of complex patterns compiled on the whole coordinate system, including all kinds of independent patterns, and in terms of production speed, mechanical properties, noise pollution and other indicators are incomparable with previous mechanical machines. [System principle] The main control equipment of the computer quilting machine is an industrial computer, which plays an important role in controlling the high-speed, accurate and stable operation of the whole machine with motion card, stepping/servo motor and frequency converter. Multi-axis motion control card is a kind of high-performance, low-cost stepping/servo motor operation and dynamic control card based on PC bus. It includes functions such as pulse output, pulse counting, digital input, digital output, etc, can send out a continuous high-frequency pulse train, by changing the frequency of the pulse to control the speed of the motor, change the number of pulses to control the position of the motor. Pulse counting can be used for position feedback of encoder, providing accurate position of machine and correcting errors generated during transmission. However, in view of the fact that the whole machine does not stop working for a long time, and the site is dusty and the environment is harsh, the industrial computer IPC of EVOC brand is adopted-586VDNH (GX) As the core of the whole control system, it plays a role of control and coordination on the motion card and frequency converter to ensure the long-term stable operation of the whole system. [System Configuration] Operating system: DOS, Linux & Wince hardware equipment: EVOC half-length single board computer HSC- 1611CLDNA IPC-6806 chassis IPC-6106P3 backplane PS- 160 power supply, others: more than two motion control cards, frequency converter [System Evaluation] The computer quilting machine solution uses an industrial computer to process and transmit the quilting machine's work, greatly improving the mechanical working mode of the traditional special frequency converter, and has strong Fault Tolerance function and over-current, overheating, multiple protection and self-testing functions have solved quilting such as saddle frame control, roller control and spindle control, and realized the automation of quilting production process.
However, with the increased prevalence of machine quilting stitches, it has become far more affordable.
