Carding analysis of PLC control system

Carding and PLC controller control system analysis newmaker welcome to e exhibition hall 1 spinning machinery exhibition hall carding machine, warping machine, opener, MAO linen textile machinery. 。 。 1. Introduction carding is the first step of spinning process, complete bale opening, removing impurity, tasks, such as mixing, conveying and combed cotton made qualified ( Known as the 'raw') By combing and article and process. Carding of removing impurity efficiency could reach 99%, is spinning out of good quality cotton, chemical fiber yarn, or the foundation of the blended yarn. Carding league system consists of a set of open scutcher machine ( Plucker, blending machine, removing impurity, etc. ) And 6 ~ 12 sets of carding machine, to grasp the cotton feeding end, sliver output begin with sequential processing of raw cotton. In the machining process, first must realize interlock control between each unit, ensure the rear machine is used to in front of the machine is used to feed cotton not disconnect, do not run empty, improve the operation efficiency of single machine, cotton to produce qualified; Second units need equipped with man-machine interface for operation and running state display, in order to realize the safety interlocking control, fault alarm and processing, ensure the correctness and reliability of production. Therefore, from the perspective of the system control to the carding system as a whole, namely using a PLC to control the whole system, and each ChanYuanJi can through the way of field bus to the remote I/O control. 2. Control system scheme system consists of a main PLC ( Premium） And several from PLC ( Micro） Add Magelis XBTG touch screen, through FIPIO field bus to realize the remote I/O control method. The main PLC with FIPIO communication interface ( Join the ChanYuanJi) And Ethernet interface ( Connection factory automation system) , all control program on the PLC controller to write; From the PLC to perform only the main PLC controller I/O image and function of man-machine interface, control program. 3. Introduction Premium PLC control system is of schneider electric's advanced medium programmable controller, USES the template type structure, high reliability, large memory capacity, and powerful system expansion ability, switch I/O and maximum capacity can reach 2048 points ( The system maximum 1024 points) Analog I/O, maximum capacity can reach 256 road ( This system the maximum is 80) ； The CPU part adopts the most advanced technology of multiprocessor, with efficient data processing capacity and processing speed ( 0 each Boolean instructions. 12 s） ； At the same time, integrated with servo control, PID closed-loop control, weighing system and advanced control technology such as 'transparent factory', is an ideal automation platform in the future. This system adopts the embedded Ethernet interface and FIPIO TSXP572823M CPU. Premium PLC FIPIO interface can connect up to 127 from the station, the transfer rate of 1 MBPS, shielded twisted-pair cable used to Daisy chain mode is combined with various from PLC; Through the powerful PL7 Pro programming software, simple configuration, Micro PLC (can be realized TSX3721/22 CPU module and TSXFPP10 FIPIO expansion card) In 64 words ( 32 input and 32 output words, see image below) In Premium PLC I/O image in the memory, the 64 words of data exchange is cyclical high speed automatic, without writing any communication program. Therefore, the main PLC remote from the PLC I/O control can be as their own memory read and write operations, realize the overall control of the carding systems. Magelis XBT——准确性 Schneider electric G touch screen is the latest company to launch the high reliability of the man-machine interface products, a variety of screen sizes ( 5. 7 '~ 12. 1)' And colour, Black and white, color) , to adopt advanced technology for 100 MHZ RISC CPU, through Windows environment VijeoDesigner VJD SPUL configuration software user interface, can provide a rich function and large amounts of data processing, and the PLC high-speed synchronous link. This system adopts the 5. 7 '(blue screen touch screen XBT G2110准确性) And through the Uni - Telway bus combined with Micro PLC programming port. Premium PLC Ethernet interface integrated with schneider electric's built-in WEB Server, advanced 'transparent factory' technology, through the connection and factory automation system network, easy access to the system in the form of browsing the site data, realize the integration of 'control'; Can through the Internet or other public network remote access operation condition of the monitoring system, reduce the system maintenance cost.
Shenzhen Coolmay Technology Co., Ltd. has created a professional team which contained with a numbers of engineers and technology experts.
A detailed plan must be developed if we hope to reach your profitability goal. Once we have a certain figure in mind, Shenzhen Coolmay Technology Co., Ltd. and our staff need to determine all the steps necessary to reach that goal and act on them.
