The utility model has compared with prior art adopted frequency converter to play the function of speed change peace srr promoter, has strengthened anti-details function, has improved the half-finished quality of rove effectively; Simplify the running program that process speed was adjusted when kind was turned greatly, simplified running program, reduced labour intensity; Improved equipment operation efficient, main motor is prolonged serviceable life, and has significantly reduced electric fault.
[description of drawings]
Fig. 1 is a theory diagram of the present utility model.
Fig. 2 is a circuit connection diagram of the present utility model.
[embodiment]
Now in conjunction with the accompanying drawings the utility model is described further.
Referring to Fig. 1, comprise Programmable Logic Controller PLC, contactor, frequency converter and main motor, the output terminal of contactor connects the input end of Programmable Logic Controller PLC, and the output terminal of Programmable Logic Controller PLC connects the input end of frequency converter, and the output terminal of frequency converter connects the input end of main motor; Programmable Logic Controller PLC is provided with control knob, travel switch, Photoelectric Detection button, shows near switch and meter length; Frequency converter also is provided with control circuit and contact switch circuit.
The main motor of fly frame is 4.7kw; adopt FRN5.5G11S frequency converter, Programmable Logic Controller PLC and contactor; core-adjustable type reactor that substituted volume is huge, fault is more and 60A contactor have strengthened speed changing function and the omnibearing protection of having realized motor to main motor.The operation of Programmable Logic Controller PLC centralized control fly frame, the electronic and running speed that starts of frequency converter may command fly frame, Programmable Logic Controller PLC is connected with frequency converter can be according to the frequency of programmed control frequency converter, thereby controls the flier speed change; Whole fly frame can change travelling speed as required by the frequency converter change in rotational speed, has improved the average velocity of whole spinning process, and the big yarn of energy, little yarn slow running, middle yarn high-speed cruising can guarantee spinning quality like this, improves equipment work efficient.The contactor that links to each other with Programmable Logic Controller PLC, but be a kind of video data, function and the touch-screen of input instruction as required, realized the man-machine communication, can allow the user understand each operation, state and timely data etc. in real time, and can be provided with and revise the inner parameter of Programmable Logic Controller PLC.Behind control circuit control contact switch circuit start frequency converter, Programmable Logic Controller PLC monitors frequency converter, monitor data is fed back on the touch-screen of contactor; And added frequency converter overcurrent determining program in the program of PLC; if be operated in below the 0-5Hz in the frequency converter certain hour; crawl only responds for the first time continuously, does not carry out for the second time and later crawl the frequency converter overcurrent protection of having avoided continuous crawl to cause like this.
As Fig. 2 is the circuit connection diagram of the utility model frequency converter and fly frame, and its operation is as follows:
1) starts
Under the situation of photoelectricity, door switch, three satisfied driving conditions such as automatic, press the QA start button, relay K A5 adhesive, the just transhipment row of its contact control of conversion device/cease and desist order FWD and contact input common port CM closure makes frequency converter just transport row.Its acceleration time, the speed of 15 seconds built-in motors slowly rose by the setting value control of frequency converter function code F07.Auxiliary reclay particularly KA5, KA6, the KA10 relay of control of conversion device adopts the JTX3-C midget relay.
2) adjusting microinching operation
Operate in the state that machine stops, and satisfy under the condition of driving, when pressing cun among the row button CA1 to CA6 any one button, relay K A6 gets electric adhesive, and its closing of contact makes frequency converter crawl operation function terminal X1 and acceleration-deceleration selection of time function terminal X2 and contact input common port CM closure.This moment, frequency converter was selected the crawl operating scheme, and the frequency of its crawl is by the setting value control of frequency converter function code C20, and the acceleration time, this moment, frequency converter did not have running frequency output by the setting value control of frequency converter function code E10, and motor can not transported; Meanwhile, another group closing of contact of relay K A6 makes relay K A10 get electric adhesive, its KA10 closing of contact makes just transhipment row/the cease and desist order FWD and the contact input common port CM closure of frequency converter, makes frequency converter accelerate to 10HZ rapidly in 0.1 second, the slow running of motor adjusting microinching.0.1 second actuation time of contact adhesive of utilization KA10, after KA6 made X1, X2 and CM closure earlier, KA10 made FWD and CM closure again, and frequency converter is the adjusting microinching running status.Select 0.1 second acceleration time, press a cun row button and just can see that flier rotates at a slow speed.Unclamp adjusting microinching button CA, frequency converter slowed down with the setting value of frequency converter function code E11 with deceleration and stops immediately in 0.1 second.When pressing the adjusting microinching button continuously, must guarantee interval greater than 0.1 second.
3) stop and anti-details
When pressing the TA stop button, KA7 gets electric adhesive, and the KA5 dead electricity discharges; Or other factor such as photoelectricity be need stop the time, when the KA5 dead electricity discharges, and the just transhipment row of frequency converter/cease and desist order FWD and contact input common port CM disconnection, frequency converter stops.Because the setting value of frequency converter function code H11 is 1, deceleration mode stops for rotating freely, and promptly frequency converter does not have output frequency, and motor is in machinery inertial and rotates freely, and stops the rotation until motor.
When the KA5 contact discharges parking, the normally closed contact closure of its KA5, it is electric that timing relay 2SJ is got, and the time-delay timing begins, after 0.50 second, the adhesive of 2SJ contact.Moving together contact and the normally closed contact of 3SJ and the adhesive of anti-details relay K A11 by 2SJ, drive anti-details electromagnet clutch coupling adhesive, make mechanical rotation throw off the 65T gear shaft that cone pulley down spreads out of and connect and slow-down, thus make rove at roller to being in loose state between the flier.Relay 3SJ gets electric time-delay constantly together, the length of delay time, and the size of decision slack generally was controlled at about 0.50 second.Obtain the loose rove of segment tension force after the parking, rove produces excessive tension force when being enough to avoid restarting machine, plays the function of anti-details.The time relay 2SJ, 3SJ adopt the JS14P digital time relay, setting value scope 0-0.99 second.
4) frequency converter indication
Represent the operation indication with frequency converter Y5A-Y5A, Y5A-Y5A closure when frequency converter moves drives relay K A8 adhesive, and pilot lamp XD2 green light is bright.When frequency converter broke down, the 30B-30C of frequency converter disconnected, and makes the KA4 dead electricity, and its contact commonly used makes the XD3 red light bright, and the expression frequency converter breaks down, and provides convenience to maintenance.
