Definitions

  • the invention relates to methods and devices for monitoring the detection or release of all sleeves or coils of an automatic bobbin changing device of a ring spinning or twisting machine, which simultaneously exchanges a plurality of full bobbins or empty sleeves between spindles and holding pins by means of gripping members, whereby according to Removing the full bobbins from the spindles by means of a light barrier which passes through an area which was occupied by the full bobbins before they were removed from the spindles, it is checked whether all full bobbins have been removed from the spindles.
  • the present invention has for its object to provide methods and devices which not only monitor whether all full tubes have been removed from the spools, but also whether all empty tubes have been delivered by the grippers to the spindles thereby avoiding unwanted winding of thread on empty spindles.
  • This object is achieved in that after the release of the full bobbins by the gripping members by means of a light barrier which runs through a second area which was occupied by the full bobbins before they were released by the gripping members, it is checked whether all the full bobbins have been released by the gripping organs and / or that after the removal of the empty sleeves from the holding pins by means of a light barrier which passes through a third area which was occupied by the empty sleeves before they were removed from the holding pins, it is checked whether all empty sleeves have been removed from the holding pins and /or that after the empty sleeves have been released by the gripping members, it is checked by means of a light barrier which runs through a fourth region which the empty sleeves had occupied before the release members by the gripping members, whether all empty sleeves were released by the gripping members.
  • light barriers are thus provided which run through the area of the empty sleeves or full coils to be released by the gripping members or to be removed from holding pins or spindles and which are interrupted when a sleeve or coil is not released or not removed, trigger a signal and interrupt the further changing process. This advantageously significantly reduces idle times and prevents damage to the changing device or the machine.
  • the light barriers are activated when the full coils or the empty sleeves should have left the area monitored by the light barriers.
  • gripping members are provided which detect both the empty tubes and the full bobbins, a light barrier is sufficient, which alternately scans the empty tubes or the full bobbins, depending on the phase of the exchange process. If, on the other hand, separate gripping members are provided for empty sleeves and for full bobbins in the changing device, a separate light barrier must be provided for each row of gripping members.
  • the light barriers must run through areas that are occupied by the empty tubes or full coils to be scanned, but are empty after removal.
  • the light barrier can be arranged stationary on the path of movement of the empty sleeves or full coils or on the component carrying the gripping members.
  • both the transmitter and the receiver can be arranged on a displacement device with which these parts forming the light barrier can be displaced into the areas to be scanned on the component carrying the gripping members. Furthermore, there is the possibility of making the gripping members and a light barrier, which is movable anyway, so movable that it can guide the light barrier into the area of the full coils to be removed.
  • the effective area of a light barrier can be shifted without shifting its transmitter and receiver in that the light beam is shifted parallel to itself by mirrors arranged in pairs, which can be folded out of the light beam in pairs.
  • mirrors arranged in pairs, which can be folded out of the light beam in pairs.
  • a transmitter and a receiver can each be arranged in a stationary manner on the machine frame in such a way that the light barrier formed by them runs through the area of the full coils located on the spindles.
  • this light barrier can be displaced parallel to itself through empty areas defined by the gripping elements or full coils defined by the gripping elements. In this case, these empty tubes or full spools are scanned on the gripping members in a position that is fixed relative to the machine frame.
  • a stationary light barrier can run on the machine frame through the area of the full coils to be removed.
  • the component carrying the gripping members contains a light barrier which runs through the area of the empty sleeves gripped. This light barrier can be installed parallel to itself through pairs of mirrors through the area of the full coils held by other gripping members.

  • the movement of the transmitter 11 or receiver 12 can take place synchronously, for example by means of stepper motors; however, the drive motors of the threaded spindles 14 can also be asynchronous motors, which transmitters 11 and receivers 12 each move to end positions which are defined by end stops or limit switches. Other mechanical elements for defining the end positions are also possible.

  • FIG. 18 III there is also the possibility that the light barrier monitoring area A is only activated when the full coils 13 have been moved out of this area. This is advantageous if threads extend in this area in an undesired manner, which would simulate full bobbins 13 which have got caught or got stuck. This avoids undesired working of the individual devices which does not correspond to the actual conditions.
  • FIG. 18 III there is also the possibility that a further area E, monitored by a light barrier, is used, which lies in the zone which could be coated by an incorrectly pulled out spindle upper part 30. This also prevents damage to the changing device or other machine elements in a simple manner.
  • optical waveguides 23, 24 and 25 are used in order to monitor the corresponding areas via light barriers 10 in order to carry out a correct changeover process.

  • One wire works with a light source, not shown, and the other with a photo sensor. The other ends of the two combined wires are directed from the transmitter area 11 to the receiver area 12.
  • lasers are suitable for this purpose.
  • This system consists of the components light source, light-guiding medium, transmitter and receiver.
  • a coherent light source for example a helium-neon laser, can be used as the light source.
  • Optical fibers with high transmission in the visible spectral range preferably single-mode glass fibers with a small core diameter, are used as the light-conducting medium.
  • An optic serves as a transmitter, which bundles and emits the light emerging from the optical fiber.
  • Silicon photo detectors with a large active area and downstream amplifier electronics are used as receivers. This results in the following functionality:
  • the light emerging from the laser is split into several partial beams by means of beam splitter plates. Each partial beam meets an optic that maps the light onto the end surface of a glass fiber core.
  • the laser light is transmitted through glass fibers of different lengths until it emerges from the fiber at its destination.
  • the light now emerging under a very specific fiber-specific opening angle is refocused or parallelized with the aid of further optics, in the simplest case an achromatic lens.
  • the beam is expanded and its beam divergence is reduced.
  • the expanded beam now bridges the work area to be monitored and finally hits the receiver. This effects a switching function as soon as the light beam is covered by an object, for example an empty sleeve 9 or a full coil 13.
  • the laser light barrier system is used to monitor the changing device on the ring spinning machine. In this case, the take-off of full bobbins 13 or the placement or dropping of empty sleeves 9 is again monitored. This process takes about 5 minutes. During this time, the laser is in the operating phase. However, the laser beam is only released for a few seconds, which the measuring process requires.
  • Transmitter 11 and receiver 12 are installed at the usual positions and provided with cover panels. On the one hand, these cover panels are intended to suppress extraneous light and, on the other hand, to prevent looking into the laser beam.
