Definitions

  • the present invention is in the field of production and quality monitoring on textile machines by determining the diameter and / or the presence or absence of a thread. Since threads are produced at a large number of production sites in the textile industry, the term "thread” is intended to encompass all types of yarns, twists, filaments and the like in the following.
  • Such monitoring is carried out, for example, on winding machines with so-called yarn cleaners, the thread being guided in the measuring gap of a sensor and its diameter being continuously monitored. If one also wanted to carry out this monitoring on ring spinning machines, then there are considerable costs due to the large number of sensors required, which among other things are due to the fact that the guarantee of the zero point stability for sensors in whose measuring gap the thread is constantly guided is not insignificant.
  • bobbins are examined in a suitably equipped laboratory. The most important parameters of the examination are the fineness of the thread and the unevenness of its cross-section.
  • This sampling control has several disadvantages. Firstly, it is not a full control; secondly, there is a considerable time lag between taking samples and testing in the laboratory and reporting the results to the operating area. Another disadvantage is the loss of the sample material, which usually only forms waste. In the case of expensive threads in particular, these waste costs can reach considerable values.
  • the invention relates to a method for on-line production and quality monitoring on textile machines by determining the diameter of a thread moving transversely to its longitudinal direction due to the formation of a thread balloon.
  • the method according to the invention is characterized in that at least one beam of rays directed from a light source onto a light receiver is placed in the thread path at the location of the transverse thread and traverses it, whereby the intensity of the beam bundle is weakened intermittently, the duration and / / or degree is used as a measure of the thread diameter.
  • the invention is based on the knowledge that when monitored at a location where the thread makes a transverse movement, the problem of the zero point stability no longer exists because the thread periodically traverses and exits the beam, which enables the zero point to be easily established.
  • the sensor can be constructed so simply that the costs of a large number of sensors remain within a reasonable range.
  • the method according to the invention also makes it possible to determine the presence or absence of a thread, in that an incomplete weakening of the intensity of the radiation beam at the appropriate point in time as a result of a thread not present (thread of zero diameter) indicates a thread break or a production stoppage.
  • the invention further relates to a device for carrying out the method according to the invention with a light source for emitting a beam and a light receiver for this sensor for determining the diameter of a thread.
  • the device according to the invention is characterized in that the sensor is arranged at a point at which the beam crosses the path of the thread during its transverse movement, and that means for measuring the degree and / or the duration of the passage of the thread through the beam shadowing resulting from the light receiver are provided.
  • a thread F coming from a drafting device runs in the direction of arrow P through a thread eyelet 1, the so-called “swab tail", and via a rotor 3 rotating on a ring 2 to a cop 4.
  • the rotor 3 divides the thread F into known manner with its rotation and winds it up on the cop 4.
  • a thread balloon is formed between the thread eyelet 1 and the rotor 3 as a result of the centrifugal force of the rotating thread F.
  • the base of the balloon forms a circle 7, the path of movement of the portion of the thread F lying in the level of the beam S and thus intersecting this is formed by a circle designated by 8 in FIG. 3.
  • the receiver 6 As long as the rotating thread F does not intersect the beam S, the receiver 6 is fully exposed to the beam S and delivers a corresponding constant output signal. Each crossing of the beam S through the rotating thread F leads to a corresponding shading of the beam S striking the receiver 6 and thus to a characteristic change in the output signal of the receiver 6. The degree or intensity of this shading is at a constant rotational speed of the thread F, a measure of its diameter.
  • the signal curve at the receiver 6 is shown schematically in FIG. 4, the time t being entered on the abscissa and the degree of shading A being shown on the ordinate. According to the illustration, at times t1 and t2, when the thread F intersects the beam S, a clear shading is registered in the receiver 6, which is symbolized by a shading pulse I1 or I2. T denotes the duration of a full revolution of the thread F.
  • FIGS. 5 and 6 show a variant with the sensor as close as possible to the base of the balloon. This increases the reliability and accuracy of the measurement because there are more stable conditions at the base of the balloon with respect to the distance of the thread F from the transmitter 5 or from the receiver 6 than in the region of the balloon tip.
  • the scanning intervals are also approximately one millimeter. This resolution is completely sufficient for determining the thread count and / or the thread unevenness; Conventional uniformity testers have a measuring length of 8 to 10 millimeters, for example.
  • the described method and the associated device have two main areas of application, on the one hand quality and on the other hand production monitoring.
  • the production monitoring can take place because the shading pulses I1, I2 (FIG. 4) and their number represent a measure of the production; when production stops, no shading impulses are registered.
  • operating data such as efficiency (using the shading impulses per operating hour) and length produced (using the total number of shading impulses) and the production speed can be determined therefrom in a known manner.
  • the device can also be used as a thread monitor. This is easily possible because the frequency of the shading pulses is known when the machine 3 is running and the rotor 3 is rotating at a given speed.
