Control system
With the development of modern technology, the application of electronic technology in the field of weaving is becoming more and more extensive, and the electronic control system of rapier looms is becoming more and more mature and perfect. Especially the progress of microcomputer control technology has transformed the operation control system of looms. Upgraded to a high-tech level.
At present, the control system of rapier looms generally has three modes: control system mainly composed of single-chip microcomputer, PLC control system and PCC control system. The loom using a microcomputer control system has a single machine console, operation panel, display and module input transfer device. The microcomputer on the loom can be networked with other machines in the workshop, and then monitored uniformly by a central microcomputer. Various information on the loom can be shared with resources, which greatly facilitates the production management of multiple machines. Some rapier looms can even be connected to the outside world’s Internet. The control of microcomputers has progressed from the original single-chip microcomputer to the current 16-bit and 32-bit computers; the display has progressed from the original liquid crystal display to the current touch-type multi-layer display technology; through the operation panel, fabric parameters, weaving process parameters, etc. can be input into the weaving process. In addition, the control system can monitor the status of the loom. Once the loom fails, it can automatically analyze the cause, automatically handle it, and alarm in time.
The mechanisms controlled by the rapier loom control system mainly include main transmission, shedding mechanism (electronic dobby or electronic jacquard machine), color selection device, electronic let-off and take-up mechanism, automatic weft finding and anti-shift device, Weft insertion tension and fixed length control, electronic selvedge and waste selvedge, automatic centralized lubrication device, etc.
The progress of the rapier loom control system has greatly improved the performance of the loom, expanded the variety of fabrics, improved the quality of the fabric, simplified the operation process, and made the entire weaving process safer and more efficient.
The electronic control system of rapier looms generally includes: electric control box, operating buttons, sensors and motors.
