Main illuminate is based on the article an advanced function development that amounts to automation product to go up in fly frame, reduce a spinner in order to reach labor intensity, make fly frame unit operation of cargo handling is decreased change, character promotes " one arrow 3 carve " . One, foreword comes nearly more than 10 years, the automation level of mechanical industry had our country spin to rise apparently, used automation technology generally on new-style spin machinery. The content of this technology contained advanced information processing and control technology, it is core with the computer namely, PLC, labour accuses machine, sheet piece the control system of the composition such as bus line of interface of machine, man-machine, spot. Advanced drive technology, servo of frequency control, communication, pace waits into electric machinery, detect pass feeling technology and actuator to wait. Cotton spin equipment has representative Electromechanical unifinication product relatively, for example new-style fly frame, the orgnaization after using automation technology simplifies, performance improvement, quality rises, the operation is convenient, promoted the class of equipment and standard. Use interface of feeling screen man-machine, the operation goes to the lavatory simply. Frequency control reduced the noise of equipment and power, reduced mechanical loss, and knit the more thorough knowledge of craft to spinning as the personage inside course of study, the function of fly frame more perfect, make homebred fly frame suits to apply in home more than importing fly frame. 2, the introduction that the stage amounts to automation product the development as automation product, the stage is amounted to already developed to be able to be offerred for the client now by manufacturer of onefold transducer production research and development PLC, lukewarm accuse implement, the diversity product such as system of driver of interface of tally, man-machine, frequency conversion, servo driver, numerical control, there is wider application in a few industries such as metallurgy, spin, medicine. Held very large market share in spin industry especially. Heibei too the professional company that spinning aircraft company all right is manufacturing spin machinery, a variety of type used a stage to amount to whole set solution -- the crucial spin equipment such as FA561A of machine of FA421A/THFA4421 of FA361A of machine of combing machine FA298A, drawing, fly frame, spun yarn, offerred a technology to assure to produce quality already, also promoted the product of the enterprise value and integrated competition ability. 3, the brief introduction that the system develops 3.

1 hardware is formed (1) pilot core component is PLC, in whole control the system is having decisive effect, type selecting when should consider its memory capacity and processing rate. The input that needs according to controlling a demand at 24 o'clock, output at 24 o'clock, and need two communication port, one of RS485 communication port will control give frequency constantly, the speed per hour when coming to those who obtain electric machinery spends control, ask to write the parameter of transducer according to spinning craft even; Join secondly go up a machine feeling screen (HMI) , will realize man-machine interaction. Give priority to module DVP32E according to afore-mentioned requirement type selecting (amount 1) , patulous module DVP08 (amount 2) . (2) the real power with integrated overall computation is 8-9kw (the mechanical clearance when every equipment is installed is different, the real power that brings about equipment also differs somewhat) , choose the electric machinery of 10kw, drive transducer type selecting is VFD150B43A, follow the principle of proper enlarge. So OK and effective consistent new facility does not have those who adjust good generation to call the police by accident as a result of machinery when moving at first. (3) the option of man-machine interface is very important, it is the main avenue of man-machine communication, everyday equipment and person contact are most is man-machine interface, it asks exterior is beautiful not only, and even durable, in spinning factory environment such more abominable conditions can ensure without reason barrier 24 hours to move for long. The stage amounts to DOP57STD interface to be blue white double color, tonal and downy, sexual price is compared tall, it is a very right choice. (4) control block diagram pursues Nextpage3 of composition of a picture of 1 control knot.

2 functional introductions hang the application with ingot already wide fly frame in 80 time our country frequency control technology, but do not have in spin domain as a result of PLC at that time very extensive due, also do not have thorough development on fly frame function so. Increase as what labour controls product itself function and knit the knowledge with more thorough craft to spinning, the function of fly frame had new development. (1) communication parameter is written contemporary transducer by more extensive promotion, but the technical force that spins cotton mill as a result of some is weak, have certain difficulty to the parameter set of transducer, those who spin weaver art is fluctuant, the technical engineer that often needs equipment to produce manufacturer will change, delay production already so, raised after service cost again. The transducer parameter communication that is based on development of this bit of consideration is written, need to revise parameter in man-machine interface only, click write can. Go to the lavatory already have reduced an operation god-given. (2) when fixed position jockeys to give birth to the head, connect that break gauze in fly frame, need to stop ingot ala to a fixed angle, such spinners just are operated easily, in inchoate fly frame it is to do not have fixed position to jockey function, need spinner hand to move pull the ala that move ingot, this kind of wrong operation often is destroyed to the quality generation of yarn, produce detail easily. Fixed position jockeys the function can solve this problem, break gauze to call the police when roving jockey when jockeying, ingot ala stops in easily the angle of contact, need not again the hand is moved pull the ala that move ingot, reduced labor to be spent gently, improved spinning quality. (3) without extremely timing because the attrition power that ingot ala passageway produces to the change of speed is different, of speed hop considerably the meeting is immortal to the tension of yarn very big impact, this function is the requirement according to spin craft, when small gauze low speed gradually increase output frequency, in gauze constant speed, big gauze gradually slowdown, beat according to inverting frequency every time very small frequency, it is the negative effect that metabolic frequency does not create didymous yarn pulling force. 4, software is developed (1) the development of development man-machine interface of man-machine program should abide by simple palpability, the principle that operates easily, realize the monitoring of data, basically include to monitor tension of picture, CCD controls picture, moving control picture, parameter to install picture, class to produce data picture, input to output a dot to monitor picture, help changes a face. Main picture refers to a graph 2, graph 3, graph 4. 1.

1 surveillant picture (see a picture 2) ask according to spinning craft, some data want to be able to be examined at any time, fall for example gauze rotate speed of speed of fixed length of long, spinning, spinning, Luo La, ingot ala rotate speed, put these data in same picture to go to the lavatory examine. Graph 2 surveillant pictures 1.

Picture of 2 moving control (see a picture 3) all control operations can realize fly frame on the picture here, include start, the dot is moved, stop and fall gauze 3 automatic implementation. Graph Nextpage1 of picture of 3 moving control.

3 transducer parameter keeps face of suitable for a painting (see a picture 4) after the transducer parameter that has set is clicked, this pushbutton can show, after awaiting about 10 seconds, parameter setting ends, pushbutton condition restores. Graph 4 transducer parameter keeps face of suitable for a painting (2) the development of PLC program asks according to craft and functional conception, after every input outputs the meaning of the dot, planning is the work out of the program, considering the capacity of the program and the concise legibility that develop a program, this program applied a subprogram in great quantities, the program distributes cake form, the modification of convenient program and search. P0: Transducer parameter is written, write in executive transducer parameter fashionable call this subprogram; P1: Give frequency immediately, transducer outputs frequency to be given according to roving inverting frequency, according to rise fast curve to alternate speed: P2: Fall gauze 3 automatic. After the program gets full gauze signal, call fall gauze 3 automatic subprograms. Electric machinery of leather belt of degree of tightness of → of signal of leather belt giving a pine is reaching the designated position to starting → loose leather belt be close to electric machinery of loose leather belt of switch bright → to stop locomotive → pace to invert into electric machinery switch of journey of restoration of leather belt of → of starting restoration leather belt opens → pace to stop to run into electric machinery. P4: Program of password test and verify. Need password enters craft parameter to set a picture, when setting parameter with subprogram of password test and verify, password test and verify passes ability to enter. 5, the efficient, maturity that the last word controls a product as labour and technical value day of beneficial rise, rate of spin machinery automation is higher and higher also, but the jumping-off place of the design even simple, good with the user with for essential, the manufacturer should be developed as far as possible on the base that does not increase systematic hardware combine technology namely practical function, make the spin machinery of our country develops to higher level.
