Describe the present invention in detail below in conjunction with accompanying drawing:
This device is furnished with source of the gas and supplies with and regulation device.Shown in Figure 1, on frame seat, be furnished with measuring roller 1, carry-over pinch rolls 2, jockey pulley 8, cord roller 7, beam of a loom 6, on beam of a loom 6, be wound with warp thread 9.Beam of a loom 6 is driven by variable-frequency motor; On the wallboard of frame seat one side, is furnished with cylinder 5; Connecting rod pivot axle 10 also is fixed on the wallboard of frame seat one side, on fulcrum shaft 10, move and be furnished with first connecting rod 11, one end of first connecting rod 11 is connected on the axle head of jockey pulley 8, the other end of first connecting rod 11 is connected with the end of second connecting rod 11-1, the other end of second connecting rod 11-1 is fixed on the synchronizing shaft 12, one end of synchronizing shaft 12 is connected with piston rod end on the cylinder 5, the other end of synchronizing shaft 12 is connected with an end of fork 3, the other end of fork 3 is allocated in the resistance-type tension force potentiometer 4, is furnished with in the circuit of lead access Electric Appliance Cabinet in the output turnover line of resistance-type tension force potentiometer 4 is chewed.
Shown in Figure 2, frequency converter wiring of input power source terminal L1, L2, L3 link to each other with the 380V power supply by breaker in the circuit, and lead-out terminal U, the V of frequency converter, W directly link to each other with variable-frequency motor M1; Photoelectric encoder U1 on the variable-frequency motor M1 links to each other with the 3rd terminal row X8 on the frequency converter; The first terminal row X5 on the frequency converter links to each other with programmable controller PLC; Swept resistance formula tension force potentiometer 4 is tension force sensing element R1, the first binding post a on the second line bank X6 on the frequency converter links to each other with the output 16 of swept resistance formula tension force potentiometer 4, the second binding post b on the second line bank X6 on the frequency converter links to each other with the 1st terminals 15 on the swept resistance formula tension force potentiometer 4, connect+the 0V power line in addition swept resistance formula tension force potentiometer 4 the 1st terminals 15, the 2nd terminals 17 of swept resistance formula tension force potentiometer 4 connect+the 12V power line.
The electrical installation principle: native system mainly is the output control motor speed of frequency converter, to reach the permanent tension principle of control.The variable frequency control principle is exactly the relation that is directly proportional with the frequency of the power supply of given motor according to rotating speed of motor, just can control rotating speed of motor so need only the frequency of control of conversion device out-put supply in variable frequency control.The frequency of frequency converter out-put supply is by the given signal deciding of frequency converter, and the given signal of frequency converter is made up of two parts, and first is by the given control signal of programmable controller PLC,
This is the benchmark control signal, and second portion is to answer component resistance formula tension force potentiometer 4 given by tension sense, mainly is to control winding tension by it.The given signal of programmable controller PLC is to be moved under what speed by push-botton operation station decision machine, and this is a basis signal.Introducing below, how resistance-type tension force potentiometer 4 signals produce: resistance-type tension force potentiometer 4 is R1 in this circuit diagram, what utilize is the electric resistance partial pressure principle, actual is a swept resistance, add the 12V DC voltage at the resistance two ends, when the swept resistance slide plate slides, output voltage on its slide plate changes along with the slide plate change in location, amplifying in the native system is the swing that the variation of winding tension causes jockey pulley 8, the swing of jockey pulley 8 compensates tension force on the one hand, cause 4 adjustings of resistance-type tension force potentiometer on the other hand, the adjusting actual conditions of resistance-type tension force potentiometer 4 are exactly moving of slide rheostat slide plate, thereby the output voltage that produces is also along with variation, so the size of winding tension is corresponding to the size of output voltage, resistance-type tension force potentiometer 4 has adopted the output of 0-10V in native system, it is transformed corresponding to 0-100%, in frequency converter inside with normal when operation tension roller 8 places the position serve as to set benchmark, if the output of resistance-type tension force potentiometer 4 just is greater than setting benchmark, frequency converter can be made adjustment so, change rotating speed of motor, adjust the position of jockey pulley 8, make the output of tension force turn back to the setting benchmark, if the output of resistance-type tension force potentiometer 4 is less than setting benchmark, frequency converter also can be made adjustment so, change rotating speed of motor, adjust the position of jockey pulley 8, make the output of tension force turn back to the setting benchmark, to guarantee constant tension winding.
The course of work: warp thread is wound up on the beam of a loom 6 through measuring roller 1, carry-over pinch rolls 2, jockey pulley 8, cord roller 7.Beam of a loom 6 is driven by adjustable frequency motor, does not draw among this motor figure.At first set the air pressure in the cylinder 5 during work, atmospheric pressure value becomes corresponding relation with warp thread 9 tension force.When warp thread 9 tension fluctuations, pressure roll 8 rotates around fixed axis, linkage drives 3 swings of position signalling output fork simultaneously, and the guide rod arm on the fork 3 drives resistance-type tension force potentiometer 4 and rotates, and the resistance variation of this rotation reflection is used for the output frequency of control of conversion device.This frequency drives adjustable frequency motor drives beam of a loom 6 and makes variable speed and rotate, and then slows down before partially as the jockey pulley position, and then quicken after partially the position.Because the agility of the signal of telecommunication is reacted, and makes adjustable frequency motor in short-term, after rotating, short amplitude variation speed can reach the requirement of location restore that makes jockey pulley for setting value.
