Detailed description of the invention
A kind of the computer brocade machine control device as depicted in figs. 1 and 2, comprise upper PC, the input of described upper PC is connected with scanner, the output of described upper PC is connected with slide cam selector and drives, described slide cam selector drives and is connected with selecting mechanism, described upper PC is also connected with slave computer, described slave computer is the control circuit be made up of PLC, the input of described slave computer is connected with external input signal, the output of described slave computer is connected with digital output signal, described slave computer is also connected with frequency converter, described frequency converter is connected with motor, described motor is also connected with large circle machine, described external input signal comprises button signal, code device signal, sensor signal and failure alarm signal, and described digital output signal comprises electromagnetic valve signal, illumination sign and CRANK PULSES.
First to pattern fabric be input in computer by scanner, change the flower pattern information on picture into decorative pattern plan of weave and pattern data again, then these can be transferred in slide cam selector control system by USB flash disk by the pattern data of needle selecting system identification, control needle-selecting blade and carry out action.By the cooperation of host computer and slave computer PLC, realize the knit control to large circle machine.
Host computer forms primarily of PC, is realized the setting of braided parameter by man-machine interface, sends controling parameters in slave computer PLC, monitors in real time the running status of large circle machine.
Slave computer is controlled by PLC, and the major function of realization has: receive the braided parameter that host computer KingView software sends, the operation that control frequency converter realizes speeds control, control large circle machine realizes various pattern.The control object of PLC mainly contains illuminating lamp, CRANK PULSES lamp, frequency converter and various electromagnetic valves etc.
Slide cam selector is the critical mechanical structure of large circle machine, slide cam selector control system is mainly used in weaving dapple fabric, instead of mechanical needle selection device in the past by piezoelectric ceramic needle selecting machine in native system design, decrease the time changing flower pattern, improve the braiding production efficiency of large circle machine.Sensor is mainly used to detect large circle machine running status, as: epimere broken yarn, stage casing broken yarn, safety door signal etc.
PLC select FX3U series, it belongs to third generation micro programmable logic controller, built-in up to 64K jumbo RAM memory, command speed is fast, function is strong, cost performance is high.By analyzing the control overflow of large circle machine, the input signal of PLC comprises: start button, stop button, inching button, clear car button, photoelectric encoder, various sensor, epimere yarn exception, stage casing yarn exception, safety door exception, frequency converter failure signal, other alarm signal etc., total input quantity 24.The output signal of PLC comprises: electromagnetic valve, CRANK PULSES lamp, illuminating lamp etc., total output quantity 11.Select FX3U-64MR type PLC, its input point, output point are 32, and I/O mouth leaves certain design capacity, to expand.
Fig. 3 is that slave computer controls main circuit diagram.It is Y2-160M1-8 that large circle machine drags mair motor model, and rated power 4KW, rated speed is 720r/min.Large circle machine needs to control rotating speed in real time in braiding process, to guarantee that braiding is steadily carried out, therefore selects frequency converter to carry out speed regulating control to mair motor.Select Ai Mosheng company EV1000-470055G type frequency converter, EV1000 Series Frequency Converter has the features such as high torque (HT), high accuracy, wide range speed control driving, and can adapt to the working environment of textile industry high temperature, high humidity and high dust very well, product reliability is high.
FX3U PLC is as the host computer of frequency converter EV1000, be connected with the RS485 control terminal of EV1000 frequency converter by 485-BD module, RS485 interface generally adopts Shielded Twisted Pair to transmit, connect so employ " multiple twin shielding " cable, and communicating by MODBUS protocol realization FX3U PLC and EV1000 frequency converter.
MODBUS agreement is the communication protocol based on industrial field bus, has become standard GB/T/T19582-2008 at China MODBUS.The bottom of this protocol communication is RS485 signal, adopts twisted pair line connection, is widely used in Industry Control, and frequency converter, the plc communication of existing numerous producer all adopt this agreement.Communication cost is also reduced while the higher communication quality of guarantee.
Because PLC is the operation being controlled frequency converter by RS485 serial-port communication, so EV1000 frequency converter action command channel selecting serial port action command mode, serial port is given etc. by the transport protocol command setting running frequency of frequency converter, Acceleration and deceleration time, speed closed loop, and realize rotating, crawl, free parking by host computer order, brake, the function such as to stop in emergency.Be normally opened contact between the sub-TA-TC of relay output end of frequency converter, as the input signal of PLC, during frequency converter emerged in operation fault, connect between TA-TC, send signal to PLC, send order of stopping in emergency to EV1000 by serial communication port, frequency converter is stopped rapidly.
The axle of frequency conversion mair motor has been installed photoelectric encoder, the mair motor rate signal collected is delivered to the high-speed counting input of PLC, the umber of pulse sent by the high-speed counter calculating photoelectric encoder of PLC, form a closed loop speed control system, ensure that the rotating speed control accuracy of frequency converter.In addition, the high-speed counter of PLC detects machine simultaneously and runs the number of turns, and be calculation squad output, total output provides parameter.
Control procedure of the present utility model is: after switching on power, large circle machine enters reset autodiagnosis state, has checked whether fault-signal, after confirming do not have fault, automatically large circle machine parameter initialization is entered state to be woven.User can set a series of braided parameter, as woven the number of turns, machine rotational speed etc., and the operational mode of large circle machine can be selected, operational mode weave cotton cloth operation, dedusting operation, crawl runs and clear car runs four kinds, selection is weaved cotton cloth after operational mode, namely machine enters normal operation, after cloth reaches preseting length, and machine automatic stopping.
The utility model selects PLC as the slave computer of control system, and itself and host computer communicate with frequency converter conveniently, reliability is high, and control system fast response time, antijamming capability is strong, and cost performance is high, compares have high reliability with SCM system.Have that structure is simple, easy to operate, reliability is high, automaticity high, improve technical performance and the production efficiency of large circle machine equipment, there is very high promotional value.
Above-described specific embodiment; the technical scheme of the utility model patent and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model patent; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
