Description

Straight twister air ring measurement apparatus
Technical field
It is especially relevant with a kind of straight twister air ring measurement apparatus the invention belongs to textile machine straight twister technical field.
Background technology
Yarn is twisted together on textile machine straight twister, a yarns among spindle, spindle is outer one, in ingot During sub rotation at a high speed, the yarn outside spindle produces air ring, if the diameter of air ring is too small, yarn easily connects with ingot tank wall Touch cause broken yarn, if air ring diameter is excessive, air ring torque is bigger, and spindle motor electric current is bigger, current of electric more it is big just More power consumptions are produced, tries one's best small and does not allow air ring is too small to touch ingot tank wall so to control air ring diameter, at present Existing method is to measure the size of air ring diameter indirectly by the electric current of spindle motor, but is measured indirectly by electric current Air ring size is not very stable and direct, because motor current size is more than relevant with air ring diameter, and is supplied with motor The relevant system of piezoelectric voltage, motor fret degree, the difference of mechanical rotating friction force etc..
The content of the invention
The purpose of the present invention is intended to overcome lacking for the existing less stable by way of current of electric measures air ring diameter Fall into, there is provided a kind of to measure the straight twister air ring measurement apparatus that directly and stability is good, precision is high.
Therefore, the present invention uses following technical scheme:Straight twister air ring measurement apparatus, it is characterized in that, described measurement dress Put including generating laser, transverse by emitters travel mechanism, laser pickoff, receiver transverse moving mechanism and control system, Transverse by emitters travel mechanism includes transmitter motor and transmitter synchronization tape loop, transmitter motor driving transmitter synchronization band Loop reciprocating rotating, generating laser are fixedly installed on transmitter synchronization tape loop;The receiver transverse moving mechanism bag Receiver motor and receiver synchronization tape loop are included, receiver synchronization tape loop drives reciprocating rotating, laser by receiver motor Receiver is fixedly installed on receiver synchronization tape loop, and transmitter synchronization tape loop and receiver synchronization tape loop are in laterally Set and the two synchronous tape loop parallel both sides for being divided into spindle outer yarn air ring spaced apart, generating laser and swash The position of optical receiver is corresponding, i.e., laser transmitter projects go out laser beam alignment laser pickoff, and generating laser and Laser pickoff synchronizing moving under the driving of respective transmitter motor and receiver motor, described control system are monolithic Machine, driver of the single-chip microcomputer with the generating laser, laser pickoff, the driver of transmitter motor and receiver motor Carry out data connection.
As the supplement to above-mentioned technical proposal and perfect, present invention additionally comprises following technical characteristic.
The laser beam that described generating laser is sent is point-like micropower laser, turns into some straight lines after launching.
Operation principle of the present invention:Single-chip microcomputer control transmitter motor and receiver motor drive transmitter synchronization to take back simultaneously Road and receiver synchronization tape loop gyration so that generating laser and laser pickoff synchronizing moving in the same direction;Sent out in laser During emitter and laser pickoff synchronizing moving in the same direction, the laser received according to laser pickoff can be defined as following three Kind:When the laser beam that generating laser is sent is emitted directly toward laser pickoff, i.e. laser beam is located at the outer of ballooning of yarn, and centre does not have There is any stop, this state is defined as strong light state;When the laser beam that generating laser is sent is stopped by space, That is between ballooning of yarn and ingot tank wall, the laser pickoff that blocks of midfeather connects laser beam to laser beam Receive, this state is defined as dim light state;When the laser beam that generating laser is sent receives the stop of ingot tank tank skin, i.e. laser connects Receive device and do not receive the laser that laser transmitter projects come completely, this state is defined as no light condition;According to above-mentioned three kinds of feelings Condition, when setting the conversion since strong light state to dim light state, single-chip microcomputer is sent to the arteries and veins of transmitter motor and receiver motor It is PN1 to rush number, sets umber of pulse that single-chip microcomputer when starting to change from dim light state to no light condition is sent as PN2, setpoint distance Umber of pulse conversion coefficient is K, and the external diameter of ingot tank tank skin is D, therefore can show that the radius R of air ring is:R=(PN2-PN1)*K+ D/2, by, it is recognised that range pulse number conversion coefficient K is industry known numeric value, outer diameter D can be by measuring ingot tank in formula Tank skin external diameter directly measures, and PN2 is constant for machinery, as long as because machine is carried out, mechanical structure is with regard to constant, only Need to once it be measured when working at the beginning, as long as so measuring PN1 numerical value in the course of the work, PN1 is sent out according to laser The umber of pulse of the point of emitter and laser pickoff when strong light state starts to dim light State Transferring can be drawn, and then be calculated Current air ring radius and diameter.
The present invention can reach following beneficial effect:This detection means is adapted to the air ring measurement of different yarns, is not required to Arrange parameter is wanted, and the size for the detection air ring diameter that can directly stablize, precision is high, and easy to detect, principle is simple, no matter while When voltage, mechanical wear change, measurement accuracy is not influenceed.
