適用する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Use] The present invention belongs to the field of controlling production and quality in textile machinery by determining the diameter of yarn and/or its presence or absence. In the textile industry, yarn is produced on many different production machines, so "yarn" here refers to single yarn, twisted yarn,
Applicable to filaments and all other types of filaments.

備された試験室で、１ケ又は多くのボビンについて行わ
れる。This type of monitoring is carried out online, for example, in winders with so-called yarn cleaners (slab catchers). In this case, the thread passes through the measuring gap of the sensor and its diameter is continuously monitored. If such monitoring were to be performed using a ring spinning machine, the number of required sensors would be significantly large, leading to increased costs. This is due in part to the fact that it is extremely difficult to ensure the zero point stability of the sensor through which the thread is associated. For this reason, production and quality control is generally limited to spot checks, carried out on one or many bobbins in a suitably equipped laboratory.
調査の最も重要なパラメータは、糸の太さとその断面の
むうである。The most important parameters of investigation are the thickness of the thread and its cross section.

It has various drawbacks. First, this is not complete control. Second, there is a significant delay between the time the sample is taken, the time it is tested in the laboratory, and the report of the results is issued and communicated to the factory. As a result, waste is generated, leading to loss of raw materials.In the case of expensive yarns, such losses due to waste become extremely expensive.
本発明の目的は、上記のスポット・チェックの欠点を除
き、コストを受容できる範囲に保って、繊維機械の生産

ことにある。It is an object of the present invention to provide a method and device that allows on-line monitoring of the production and quality of textile machinery, eliminating the above-mentioned drawbacks of spot checks and keeping costs within an acceptable range.
本発明は、バルーニングのためその長さ軸方向に直角に
運動する糸の直径を求める事により、繊維機械における
生産と品質をオンラインで監視する方法に関する。The present invention relates to a method for on-line monitoring of production and quality in a textile machine by determining the diameter of a thread moving at right angles to its longitudinal axis for ballooning.
本発明による方法では、少なくともとも１つのトランス

として用いられる。In the method according to the invention, a beam from at least one transmitter to a receiver is arranged in the path of a perpendicularly moving thread, the intensity of the beam being increased by the perpendicularly moving thread across the beam. The duration and/or extent of the attenuation of the strength is used as a measure of the diameter of the thread.

の構？＠＆よ簡単となり、コストもその数が多数必要で
あっても受容しうる限度内に納めることができる。The present invention shows that in the region where the thread moves perpendicular to the axis, the thread passes through the beam periodically and leaves again, so the zero point is easily found and the luck of zero point stability no longer exists. I am also inspired by the fact that Therefore, what is the structure of the sensor? It is simple and the cost can be kept within an acceptable limit even if a large number of them are required.
本発明による方法は、期待される時点においてビーム強
度の減少が欠如することが糸が存在しないこと（糸直径
Ｏ）を示し、糸切れまたは生産の停止を意味するので、
もちろん糸の存否を求めるのに用いることもできる。The method according to the invention is advantageous since the lack of a decrease in the beam intensity at the expected time point indicates the absence of a thread (thread diameter O) and means a thread breakage or a stoppage of production.
Of course, it can also be used to determine the presence or absence of threads.

手段を設けたことを特徴とする。The device according to the invention locates the sensor so that when the thread moves perpendicular to its axis, its path intersects the beam, and the shadow produced at the receiver, i.e. the decrease in the light intensity, occurs when the paternity passes through the beam. It is characterized by providing means for measuring the degree and/or period.
以下、本発明の詳細を添付の図を用いて説明する。図は
それぞれ次の通りである。Hereinafter, details of the present invention will be explained using the accompanying drawings. The figures are as follows.

リング２上を回転するトラベラ３によりボビン４に至る
。1 to 3 schematically show the spindle of a ring spinning frame with the ballooning of the yarn. As shown in the figure, the yarn F sent from the draft mechanism (not shown) passes through the yarn guide 1 and travels in the direction of the arrow P.
The traveler 3 rotating on the ring 2 reaches the bobbin 4.
トラベラ３はその回転を、４Ｆに公知の方法で伝達し、
糸はボビン４に巻き取られる。糸のバルーニングは系ガ
イドｌとトラベラ３の間で、旋回する糸の遠心力で形成
される。Traveler 3 transmits its rotation to 4F using a known method,
The thread is wound onto the bobbin 4. Yarn ballooning is formed between the system guide 1 and the traveler 3 by the centrifugal force of the spinning yarn.
ビームＳを放射するトランスミッタ５と、このビームを
受は取るレシーバ６は、糸のバルーニングの領域中に、
旋回する系Ｆが周期的に、即ち１旋回の間に２回ビーム
を遮るように配置される。A transmitter 5 that emits a beam S and a receiver 6 that receives this beam are arranged in the region of ballooning of the thread.
The rotating system F is arranged periodically, ie, so as to interrupt the beam twice during one rotation.
第３図に示すごとく、バルーニングの基面ば円７を形成
し、ビームの高さ水車にあってビームを遮る糸の一部Ｆ
の運動経路は１つの円８を形成する。As shown in Figure 3, the base of the balloon forms a circle 7, and the height of the beam is F.
The motion path of forms one circle 8.

は取られるビームの強度は、系Ｆの直径の測度となる。As long as the rotating system F does not interrupt the beam S, the receiver 6 receives the full intensity of the beam S and produces a corresponding constant output signal. Whenever the beam is interrupted by the rotating thread, the receiver 6
The beam S arriving at the receiver is attenuated, resulting in a characteristic change in the output signal at the receiver. The extent of this shading, ie the intensity of the beam taken, is a measure of the diameter of the system F.

間を示す。FIG. 4 shows changes in the signal from the receiver 6. Time is plotted on the horizontal axis, and the degree of light shielding is plotted on the vertical axis. As can be seen from the figure, at the time point and t2, the system F intercepts the beam S, and the fact of the shielding is clearly recorded in the receiver 6, as indicated by the shadow impulse II, 12. T indicates the period of one rotation of the thread F.
第１図ないし第３図の配置では、センサは系ガイドｌに
比較的接近して、即ちバルーニングの頂部に位置してい
るが、第５図、第６図は一変形を示し、ここではセンサ
はできるだけバルーニングの基部に近く配置しである。While in the arrangement of FIGS. 1 to 3 the sensor is located relatively close to the system guide l, i.e. at the top of the ballooning, FIGS. 5 and 6 show a variant, in which the sensor should be placed as close to the base of the balloon as possible.
バルーニングの基部では頂部におけるよりは、トランス
ミッタとレシーバからの糸Ｆの距離に関しては、より安
定した条件に支配されるので、測定の信頼性と精度は改
善される。The reliability and accuracy of the measurements is improved since more stable conditions prevail with respect to the distance of the thread F from the transmitter and receiver at the base of the ballooning than at the top.
既に述べたごとく、この方法では、トラベラの回転毎に
２回の糸直径の測定を可能とする。As already mentioned, this method allows two measurements of the thread diameter per revolution of the traveler.
糸Ｆは各回転毎に糸軸方向には１ｍｍのオーダでしか移
動しないので、走査間隔も約１ｍ＋ｎのオーダとなる。Since the thread F moves only on the order of 1 mm in the thread axis direction for each rotation, the scanning interval is also on the order of about 1 m+n.
この分解能は糸の太さ及び／又は不均一性の測定には極
めて満足すべきものである。This resolution is very satisfactory for measuring thread thickness and/or non-uniformity.

たる適用分野を持つ。即ち、品質の管理と、生産の管理
の分野である。The method according to the invention and the device implementing it have two main fields of application. That is, the areas of quality control and production control.
品質は、例えば糸の太さ、あるいは撚糸中の単糸の本数
などを監視することで管理されよう。Quality may be controlled by monitoring, for example, the thickness of the threads or the number of single threads in the twist.

ことができる。Just like in known laboratory testing machines, the results of the yarn cross-section or thickness measurements can be used to derive other parameters, such as unevenness values, spectrograms, etc. Therefore, in the method according to the invention, additional parameters can also be derived from the large number of data points obtained by measuring the degree of shading.

られ、これらのデータから生産速度も公知の方法で求め
ることができる。Since the shadow impulse t+,[2 (FIG. 4) and its number serve as a measure of production, it is also possible to monitor the production process. When production stops, shadow impulses are no longer recorded. The method of the invention can therefore be used to obtain operational data, such as efficiency (determined from the number of shading impulses per operating time), production length (determined from the total number of shading impulses), and from these data the production rate can be determined. can also be determined by a known method.

れは容易に可能である。If the shadow impulses are not only evaluated according to their amplitude (diameter determination) and/or their number (operational data), but also the occurrence of shadow impulses is monitored, the device according to the invention can be used as a thread breakage detector. can also be used. This is easily possible since the frequency of the shadow impulses is known for a given rotational speed of the traveler 3 when the machine is running.
