Domestic software computerized quilting embroidery machine control system

2020-09-24

computerQuilting embroidery machineThe key skill of the control system is the linkage control skill of the saddle frame and the roller and the needle row. The computerized quilting embroidery machine adopts multi-CPU parallel processing technology to process and transmit data for the computerized quilting embroidery machine operation, which greatly improves the previous traditional dedicated inverter The mechanical operation method of the company better handles the key quilting skills such as saddle frame control, roller control and spindle control, and completes the automation of the production process of quilted products. It has strong fault tolerance, automatic shutdown of broken wires, and overheating. Maintenance and other automatic detection and maintenance measures and self-diagnosis ability of system failures. In addition, it has more than 40 functions in 5 categories, such as parameter setting and pattern management. It is satisfied that many quilting processing enterprises are satisfied with various multi-needle shuttle quilting embroidery machines, Multi-needle shuttleless quilting embroidery machine, multi-needle rotary shuttle quilting embroidery machine, and single-head rotary shuttle quilting embroidery machine meet the urgent needs of new machine adaptation, old machine transformation and quilting processing.

The overall skill planning of the control system of the quilting embroidery machine has a high starting point, good compatibility, and strong anti-interference ability. It is optimized according to the conventions of world planning and the specific requirements of the computer quilting embroidery machine. The characteristics of its skills are mainly reflected in the following aspects:

1) In the control skills of the saddle frame and roller system, select the saddle reasonably according to the actual load of the saddle frame or roller, the principle of ball screw and belt transmission, the speed and stitch of the quilting needle, the phase of the quilting needle and the pressing plate, etc. Frame or roller drive motor, accurately calculate saddle frame or roller acceleration and material moving time, optimize the planning of saddle frame or roller drive command control curve, ensure quilting embroidery quality and quilting output value, and improve the overall planning level of saddle frame or roller system control skills. Use stepping motors instead of communication servo motors to drive the saddle frame, and then improve the overall performance of the saddle frame and roller system.

2) In the spindle system control skills, according to the actual load of the spindle, the principle of belt transmission, quilting needle speed and quilting stitch, etc., a reasonable selection of the spindle drive motor, calculation of the spindle acceleration, and optimal planning of the spindle drive command variable speed control Curve, to ensure the quality of quilting embroidery and the output value of quilting embroidery, improve the overall planning level of spindle system development skills, and use frequency converters to bring differences.

3) In terms of the hardware and structure of the entire system, optimize the circuit diagram of the planning system according to the system performance and functional indicators, carefully carry out technical measures such as system resistance to industrial environment planning, system performance and operation stability planning, and system safety planning, and strictly select elements Device control and derating planning methods, reasonable selection of computer chips and various components and integrated circuit chips, to complete the required functional units with the best price and highest reliability. Adopt shielding, thermal planning and correct wiring methods to complete electromagnetic compatibility in industrial environments.

4) In the system control software, in view of the inherent nature of software defects and the complexity of the error environment, a series of preventive measures have been adopted in the software planning, and various actuators have been monitored during the quilting process to prevent interference Misoperation caused by other factors improves the reliability of the system.
