Definitions

  • the invention relates to a device for thread monitoring on a textile machine according to the preamble of claim 1.
  • Such devices are mounted, for example, on the creel of a warping system in order to carry out a life check on the individual threads drawn off the bobbins. If a thread breaks, the winding system is automatically shut down.
  • a device of comparable generic type has become known, for example, from DE-C-29 15 749 by the applicant.
  • the control signal is triggered when the guard needle is swiveled out by touching electrical contacts.
  • the control signal is triggered in that the swinging-out guard needle interrupts a light beam directed at a photocell.
  • Such a thread monitor is known for example from CH-A-417 491 or from US-A-4,100,425.
  • Most known thread monitors are also provided with a device with which the guard needle can be blocked in the operating position, so that individual needles can remain empty in a row of guard needles arranged side by side without a control signal being triggered.
  • a disadvantage of the known devices is that the existence control on the one hand and the quality control on the other hand have to be carried out in different components and at different locations. This considerably increases the outlay on equipment and the possibilities of a malfunction.
  • numerous thread loops and thread passages are required, so that a relatively long time is required for threading.
  • the large additional thread deflections e.g. when merging and reopening the threads also increase the risk of thread breaks. It is therefore an object of the invention to improve a device mentioned at the outset in such a way that not only the existence control but also the quality control of the thread can be carried out in a single structural unit. This object is achieved according to the invention with a device which has the features in claim 1.
  • the light beam not only runs through the swivel range of the guard needle, but also through the thread plane itself, so that it takes on a double function.
  • the control signal is triggered both by irregularities in the thread or changes in the position of the thread, as well as by a light needle passing through the light beam, and the device is stopped.
  • only a single circuit is required to operate the light transmitter / light receiver arrangement.
  • the distance between the creel and winding machine can be reduced because of the quality control can already be carried out directly on the creel.
  • Figure 1 is a winding system 1 such as a warping plant shown in side view. It consists of a winding machine 2 and a creel 3.
  • Coils 4 are attached to the creel 3, the threads 5 of which each pass through a thread tensioner 6, which generates the desired thread tension. Subsequently, each thread passes a thread monitor 7 according to the invention, in which an existence or. a quality control is carried out.
  • the thread monitors 7 are each combined in rows, as will be explained in more detail below.
  • the threads arrive directly at the cross reed 8, in which the threads 5 are given a specific position in order to be fed as a thread assembly 10 to the warp reed 9, in which the thread assembly 10 receives its warping bandwidth.
  • the tapes are wound onto the warping drum 12 in a known manner via deflection rollers 11. If one of the threads guided by the thread monitor 7 breaks, a control signal is produced which immediately stops the winding machine 2. The same thing happens when a thread has an irregularity such as a fluff, a spinning defect, or a knot. When the machine is stopped, an optical signal can be triggered, which signals the operator the location of the source of the error.
  • FIGS. 2 and 3 The structural design of the device according to the invention can be seen more clearly from FIGS. 2 and 3.
  • Several housing sections 18 are held together by threaded rods 26, 27.
  • a guard needle 19 is pivotally mounted on an axis 21, which runs approximately at a right angle to the thread direction.
  • the guard needles 19 are angled parallel to the thread and project with their free end through a slot 34 in the housing section.
  • a thread sensor 20, which can be pressed against the thread 5, is arranged at the end of each guard needle.
  • the watchdog needles could also be stored in a one-piece housing.
  • Each axis 21 is connected to a lever arm 13, at the end of which a tension spring 25 is attached to generate a spring preload.
  • the tension spring 25 can either be fastened to the inside wall of the housing, or it can be snapped into a catch 32 on the outside of the housing, as shown for example in FIG. 6, so that the spring tension is adjustable. Instead of the catch 32, the spring tension could also be adjusted, for example, with an adjusting screw or the like.
  • Each thread 5 is guided by a fixed thread guide 22 on the housing section 18 and by an adjustable thread guide 23 behind the housing section.
  • the adjustable thread guide 23 is arranged such that the thread is angled slightly after passing the thread sensor 20.
  • the spring preload of the guard needle 19 is set such that the guard needle is pressed against a stop 24 in the operating position. This stop is formed by a section of the slot 34. In the operating position, the thread 5 runs approximately parallel to the upper side of the housing section 18.
  • the housing sections 18 are laterally closed by end sections 14 and 15, respectively. Each of these end sections carries a raised housing section 28 which projects beyond the top of the housing sections 18. On this raised housing section, a light transmitter 17 is arranged on the end section 14 and a light receiver 16 on the end section 15. The light transmitter 17 is directed at the light receiver 16 and emits a light beam 29. This light beam 29 runs in the plane of the tensioned threads 5 in the operating position of the monitor needles 19 and at the same time in the pivoting range of the monitor needles 19. A signal lamp 31 is also arranged at the end section 15, which lights up when the machine stops. Both end sections 14, 15 carry the adjustable thread guide 23 on a cantilever. This can be adjusted in the cantilevers by means not shown in detail.
  • the guard needle 19 is pivoted from the operating position shown in FIG. 3 under the influence of the spring 25 into an alarm position which is shown in FIG. 5.
  • the guard needle 19 rests against the stop 30, which is also formed by a section of the slot 34.
  • these stops could also be made using adjustable components are formed so that the relative position of the guard needle can be set in the operating position or in the alarm position.
  • FIGS. 4 to 6 The function of the device in the event of a thread irregularity can be seen from FIGS. 4 to 6.
  • a fluff or a knot 33 has just passed the light beam 29, a reduced light intensity being measured at the light receiver 16. This deviation is sufficient to trigger a control signal which can be used to shut down the winding system.
  • the difference in light intensity can form a measure of the disturbance variable, so that the measuring and control device can be set in such a way that no control signal is triggered in the case of small disturbance variables.
  • the position of the guard needle 19 does not change when a thread irregularity is ascertained.
  • FIG. 5 shows the breakage of a thread 5, the guard needle 19 swiveling out of the operating position into the alarm position and thereby crossing the light beam 29.
  • the stop 30 can, however, also be arranged such that the light beam 29 not only crosses through in the alarm position, but is completely interrupted.
  • a flag or screen could also be arranged on the guard needle 19.
  • the photocell or the light receiver 16 registers the temporary or, if appropriate, the permanent interruption of the light beam and in this way likewise puts the winding machine out of operation.
  • the guard needle also reaches the area of the light beam 29 and thereby triggers the control signal to stop the device.
  • the stop 30 is preferably arranged in such a way that the guard needle passes completely through the light beam without a thread and lies outside the light beam in the alarm position. In this way, individual guard needles can remain empty without locking.
  • the device is functional both in the alarm position and in the operating position.
  • FIG. 1 Another function of the device according to the invention is shown in FIG. An overvoltage of the thread can then also trigger a control signal.
  • the guard needle 19 In the case of an inadmissibly overstretched thread 5, the guard needle 19 is exposed to leverage under the effect of the resultant force C. This causes the guard needle 19 to spring back somewhat, so that the thread position shifts by the angle alpha. This thread deviation can also be registered by the light receiver 16.
  • the watchdog needle must be somewhat resilient for this function.
  • the looping or the deflection of the thread can be changed in that the adjustable thread guide 23 either in the direction of arrow A, i.e. is adjusted in the direction of the thread 5, or in the direction of arrow B in the pivoting plane of the guard needle 19.
  • a clearly visible signal lamp 31 can also be activated so that the operating personnel can immediately locate the location of the fault.
  • a pivotable and spring-loaded guard needle 19 is held by the thread 5 in an operating position.
  • a light beam 29 is directed from a light transmitter 17 onto a light receiver 16. If the light intensity deviates from a predetermined target value, a control signal is triggered, with the aid of which the system can be stopped.
  • the control signal is triggered both by a thread irregularity and by a pivoting of the guard needle 19. Even sheer Positional deviations of the thread can trigger the control signal.
