Description

Flat knitting machine yarn measuring device

Technical field

The present invention relates to a kind of yarn measuring device (Yarn measuring device), be meant a kind of yarn measuring device that is used for horizontal volume machine (Flat bed knitting machine) especially.

Background technology

Produce for the factory of cloth for utilizing horizontal volume machine, the cloth that every horizontal volume machine or each braiding will be produced can keep stabilized quality, its key just is the size control of yarn degree of being knitted to order (Stitch), and this degree purpose size promptly is to be colluded by knitting needle (Needles) to draw the number of yarn to be caused, when the factory of weaving cotton cloth needs same cloth of a large amount of productions, with regard to the cloth degree order size that every horizontal volume machine must be produced, be controlled at identical size as much as possible, yet, when the cloth degree order of being produced when different horizontal volume boards varies in size, make knitting needle collude and draw the mountain hornblock (Cam) of yarn action just to know and to be adjusted; But problem degree of being purpose size with the naked eye is to be not easy to be distinguished, so just must reach with measurement mechanism than science, that is to say can be by measuring the consumption of horizontal volume machine yarn when operating, compared and determine the degree order of horizontal volume machine that is bigger and that is little, so can know just how this removes to adjust the mountain hornblock high and low position of that horizontal volume machine, and reach the cloth steady quality.

Known to the U.S. the disclosed the 6th, 112, No. 557 " FLAT BED YARNMEASURING DEVICE AND METHOD (flat knitting machine yarn measuring device and method thereof) " patents, shown in Fig. 1～3 of this known patent, its device major technique is characterised in that when horizontal volume machine operates, yarn (Yarn) 17 can drive a roller (Wheel) 19 earlier and rotate, and receive and add up the quantity of this roller 19 signal of turn-taking that produces via the s operation control box that is electrically connected with it (Logic circuit control box) 21, and at knitting needle row bed (Needle bed) 13, when sliding support body (Carriage) 10 set inductor (Sensor) 24 of 14 tops produce displacement on slide rail (Track) 15, three that can be subjected to being set firmly on the fixed cross bar (Bar) 25 have the playback magnet (Home magnet) 26 that predetermined knitting needle is counted spacing (Distance), one first magnet (Firstmagnet) 27 and one second magnet (Second magnet), 28 inductions, and produce reset signal respectively, initial signal and end signal, these signals also can receive and can make this s operation control box 21 reset and make zero via the s operation control box 21 that is electrically connected with this inductor 24, control the statistics starting point of the signal of turn-taking that this roller 19 produces and control the statistics end point of the signal of turn-taking that this roller 19 produces; For example when this horizontal volume machine be 12 cut horizontal volume machine the time; represent that promptly this horizontal volume machine per inch has the quantity of 12 knitting needles; so the predetermined knitting needle number words that are 100 knitting needles; then predetermined knitting needle is counted spacing and is about 8.33 inches (inch); then be about 21.1 centimeters (cm) after the conversion metric unit; this predetermined knitting needle of institute is counted the spacing that 21.1 centimeters of spacings are this first magnet 27 and second magnet 28; this playback magnet 26 is fixedly arranged on then that above-mentioned predetermined knitting needle is counted the outer of spacing range and near these first magnet, 27 places; when this horizontal volume machine comes into operation; sliding support body 10 drives synchronously earlier promptly that this inductor 24 is moved to these playback magnet 26 places and the replacement of sensed back is made zero; this roller 19 of this yarn 17 this moment drive earlier rotates to produce turn-takes signal to this s operation control box 21; signal does not begin to receive and statistics but this s operation control box 21 is turn-taked to this; when treating that this sliding support body 10 continues to be moved to this first magnet 27 that closes on; 24 of this inductors are sensed and issue a signal transmitted to this s operation control box 21; the signal of turn-taking that this s operation control box 21 can continue to be produced with this roller 19 begins to receive and accumulative total; and this sliding support body 10 continues to be moved to above-mentioned predetermined knitting needle when counting second magnet 28 that spacing (100 knitting needles are about 21.1 centimeters) locates; 24 of this inductors are sensed and issue a signal transmitted to this s operation control box 21; this s operation control box 21 can be ended to receive and accumulative total to the signal of turn-taking that this roller 19 continued to produce; can shut down the display (Display) 42 of watching this s operation control box 21 this moment; this s operation control box 21 promptly can be according to import circumferential edge that the central point of setting this roller 19 extremely contacts with this yarn 17 in advance must radius (r); or circumference (circumference formula: L=2 π r to import in advance; pi=3.1416); the quantity that signal received of turn-taking with this roller 19 of accumulative total; calculate this predetermined knitting needle of institute and count the total amount of used this yarn 17 of spacing (i.e. 100 knitting needles) (that is: circumference x receives the total accumulation of the signal of turn-taking); or used amount of thread when promptly can be converted into every knitting needle degree order divided by 100 again; this promptly can be used to judge or compares its degree purpose size, in order to the foundation of judging as the displacement of adjusting mountain hornblock height.

But by the major technique feature of this known flat knitting machine yarn measuring device as can be known, its clearly and essence exist some defectives and problem and remain relevant dealer and promote, be listed below:

One, this known flat knitting machine yarn measuring device only can unidirectionally be measured; Because in the disclosed device of this known case, have one and need the playback magnet 26 of resetting and making zero before the signal beginning to receive to turn-take, and from its technology contents, if remove this playback magnet 26, or, also can't be easily learn that according to its technological means how to implement could bidirectional measurement again in adding a playback near these second magnet, 28 places during magnet 26; Because if reset when making zero when its nothing is provided with any one magnet 26 that playbacks, this s operation control box 21 will not have forever and ends most lasting accumulative total, just can't calculate suitable measured value yet; Yet, if when the two ends beyond 28 of this first magnet 27 and this second magnet all are provided with playback magnet 26, then this s operation control box 21 is at this inductor 24 by 27 inductions of this first magnet and after beginning accumulative total, arrive this inductor 24 is finished accumulative total by these second magnet, 28 inductions moment again, the also still following computing of this s operation control box 21 is made zero with regard to resetting near another playback magnet 26 of these second magnet, 28 ends and can't computing; Therefore can assert that this known technology essence has only disclosed the one-way fashion measurement mechanism just can measure after all need allowing 26 replacements of playback magnet make zero before each measurement.The defective that only provides unidirectional measurement and produced is on the sliding support body in order to driving the mountain hornblock of knitting needle, and the used mountain hornblock of used mountain hornblock and backhaul displacement is inequality when removing Cheng Weiyi; Yet, existed because the mountain hornblock more or less permits tolerance on processing and fabricating, add the deviation in the assembling, therefore adjust the mountain hornblock if only have Cheng Weiyi can measure used amount of thread, and the backhaul displacement can't be measured and adjust the mountain hornblock, will cause the degree order cloth of different sizes.

Two, the measured value error range of this known flat knitting machine yarn measuring device is excessive; Owing to yarn 17 is constantly advanced yarn by the horizontal volume machine in the running is used, therefore the periphery of this roller 19 contacts with yarn 17 frictions, yarn 17 can continue to drive roller 19 and rotate, yet above-mentioned to have described this in detail known be to measure yarn-using amount as the number of turns that this roller 19 how rotates, therefore we can know the error range size of knowing its measured value, depend on roller 19 circumferences that contact with yarn 17 frictions fully, roller 19 radiuses that maybe can say so and to determine circumference; Because the curtailment that yarn 17 contacts with the circumference friction of roller 19, slip may be caused and roller 19 rotations can't be driven, when this situation takes place, measured value is unsubstantial meaning then, therefore to avoid this kind situation to take place, preferably can increase the length that yarn 17 contacts with the circumference friction of roller 19, also just equaling to increase the circumference of roller 19 or the radius of saying so earlier, yet, when increasing the circumference of roller 19, also just equal to have increased the error range of measured value, because the measurement of yarn-using amount is to come computing with the number of turns that roller 19 rotates, when yarn-using amount just made roller 19 rotate near a circle but not to a circle, this yarn-using amount that does not reach a circle was the error amount that is produced when it is measured, in any case and this known technology reduces the circumference of roller 19, the error range of its measured value is still excessive.Lift row, with reasonable and enforceable minimum roller radius is 0.25cm, and its circumference approximates 1.57cm, the error range that is to say its measured value about 0 to 1.56cm, be that the worst error value is about 1.56cm, so big error amount does not have accuracy to say really.

Three, this known flat knitting machine yarn measuring device quite inconvenience when reading measured value; Because the s operation control box 21 of this known technology is arranged on the sliding support body 10, the display 42 that shows operation result is again on s operation control box 21, so want the shown operation result of reading displayed device 42, must just can see display 42 to the position after these sliding support body 10 displacements, for the user, bring inconvenience really.

This known flat knitting machine yarn measuring device is very loaded down with trivial details when adjusting the mountain hornblock; Because the mountain hornblock of this known technology, treat that the 10 position of rest movements of sliding support body just can read the operation result on this s operation control box 21 when doing, just can staticly adjust the mountain hornblock, and the adjusted result of mountain hornblock, must treat just can read again when sliding support body 10 position of rest movements are next time done the operation result on this s operation control box 21 again, and then carry out next time mountain hornblock adjustment, make the user feel very loaded down with trivial details in fact, this kind can't be when the continuous displacement of sliding support body operates, the device that directly reads this operation result and directly fast the mountain hornblock is dynamically adjusted has not been inconsistent the market demand in fact.

Summary of the invention

So, the main purpose of flat knitting machine yarn measuring device of the present invention, be all can measure when reaching two-way braiding degree order, measuring accuracy improves, can be more directly and conveniently read measured value and can be more easily and the multinomial effect of rapid adjustment mountain hornblock displacement, reach accurate Calculation with the aggregate demand of yarn, the purpose that promotes the cloth quality and enhance productivity.

For realizing above-mentioned purpose, the present invention proposes a kind of technical scheme of flat knitting machine yarn measuring device, described horizontal volume facility have a support, one is horizontally placed on the knitting needle row seat on this support, but parallel this knitting needle row seat and be arranged at slide rail and the sliding support body of striding frame horizontal displacement on this slide rail directly over it, the two ends of this sliding support body respectively are provided with a mountain hornblock control module, and an end has also extended a baffle board, and described yarn measuring device includes: one is arranged on this support and the counting unit of close this slide rail end, this counting unit axle is established the grating roller that a circular array equidistantly is provided with a plurality of perforation, this grating roller extension is installed with a main roller, and the inductor of a U type, and this grating roller stretches between between these inductor two ends; One is located at the sensing unit on this support with this knitting needle row parallel and relative this baffle board of seat, this sensing unit is with default spacing branch be arranged first inductor and second inductor of U type; An and calculation process control module able to programme of being located at this support limit, this calculation process control module able to programme has arithmetic processor, display and the control interface able to programme of mutual electrical connection, and this calculation process control module able to programme also is electrically connected with this counting unit, this sensing unit, this sliding support body and this mountain hornblock control module.
