Definitions

  • the invention relates to a method for control a warping machine, in particular a cone warping machine, with the threads to be wound onto a warp drum wound up and then together by this onto a warp beam a tree-rearing machine, in which the leading End of a thread broken during warping on the Warping drum is wound and the trailing end of the break after a winding stop, provide a marker and with the leading end of the break is wound unconnected, and where at the break during the rearrangement a Breaking releasing rearrangement stop is carried out after which the two ends of the break are joined together and that Rebuilding continues.
  • Thread breaks can occur during warping which the warmer side, i.e. leading break end is wound up, although after detection of the thread break an immediate rewind stop was carried out. Usually can now the warping drum from the stop position be turned back until the leading end of the break exposed. Such turning back is due to the material or not always permissible for other reasons. In this The trailing end of the fall with a paper strip trained markers and the straight enclosed warmed band. In addition, such Pressing a memory key on a computer, with which every unrepaired thread break by storing in Calculator is detected.
  • Thread break saved, but also the already sharpened Thread length or the number of revolutions of the warping drum since the beginning of warping and a key figure for the belt in which the thread break has occurred (see e.g. DE 34 32 275 A).
  • the invention is based on the object a method with the method steps described above to improve so that misconduct in warping and / or trees and wasted time.
  • the marker is used to convert the tree machine in this way stop that the Umbäumstop is reliably brought about. It is then not possible for the thread break or the trailing end Break end can be wound on the warp beam.
  • the rearrangement stop is brought about mechanically, namely with a sensor. The operating errors described at the beginning by not pressing a memory key on a computer or reacting too late to the sighting of the marker at Rearrangements are avoided. It is achieved that during the Rearranging other work can be done without rearrangement errors to fear.
  • the process is preferably carried out so that the Control signal is generated when the marker overlaps past the sensor. Once the marker Passing the sensor, the control signal will be brought about of the Umstäumstop generated. Since there is no coulter coverage when the marker passes the sensor, can also use sensors with comparatively low sensitivity be used.
  • the method can also be carried out so that the control signal is generated when the marker with a Thread sheet coverage of a predetermined number of layers on the sensor passes by.
  • the control signal generated by the marker is generated early in this case.
  • the warping drum must turn several more times, namely the predetermined number of layers accordingly until the thread break the tying machine or has reached the repair site.
  • This method is particularly suitable for high re-treeing speeds and then when the stopping process does not take place during the rearrangement may be done abruptly, because otherwise the threads would close be heavily used or the thread breakage is not precise enough can be achieved.
  • the potting machine be used with the Control signal is switched off and to a standstill expires, after which a rewinding of the thread sheet on the The warping drum is operated until the broken ends are exposed for connection.
  • This procedure is particularly gentle on the thread, though is slowed down. It is also not time consuming because Pre-switching with subsequent crawling gear avoided becomes. Because the pre-shutdown must be with a not exactly predictable Safety factor take place that costs time. In contrast, rewinding only takes as long to become like the overflow time. The overflow time However, is of different lengths, so that the the aforementioned method results in a reduction in the time required, that of generating the control signal for the rearrangement stop until the machine is actually stopped in the repair position is required. This procedure is particularly then performed when the control signal is generated, if the marker passes the sensor without covering the coulter.
  • the piling machine be equipped with the control signal switched into a crawl gear and then is automatically switched off when necessary when the marker has reached the sensor thread without thread coulter coverage. In this case, an overflow of the thread break is avoided. A fully automatic positioning of the tree machine results and the warping drum or the thread break, around the latter to repair. There is a double use of the marker, namely for switching on the creeper and to finally switch off the rearrangement process.
  • early detection of the marker by the sensor is required, that is, if the marker is not yet directly connected to the sensor is adjacent. This procedure is therefore particularly then performed if the control signal is generated when the marker with a thread share coverage predetermined Number of layers past the sensor.
  • each thread break at one Rewind stop stored in a computer and one measured warp thread length is assigned that when rearranging a pre-cut-off signal using the measured length of the warp is generated by the computer with which the tree-making machine in a crawl gear is switched, and that the taming machine from the crawl gear is turned off completely when the marker has reached a position activating the sensor.
  • the procedure is particularly useful when early detection is not possible, e.g. when winding metallized Threads. So it is partly done as with the previously known State of the art. Registration of the thread break in the computer with a memory key is used when an overflow when converting is not possible because the thread coulter cannot be rewound and the rearrangement stop the exact position of the thread break must result.
  • the invention also relates to a warping machine, especially cone warping machine with a thread to be wound band-wise warping drum, with one wound up Threads from the warping drum to a warp beam Potting machine, with a wrap, in which the Arches leading breaking end of a broken thread the warping drum wound up and the trailing end of the break after a winding stop, provide a marker and with the leading end of the break is wound unconnected, and who when rearranging at the break point with the release of the Stop breaking ends.
  • the machine is trained that a scanning the entire width of the warp beam during rearrangement Sensor is present, depending on the Marker a control signal initiating the stopping of rearrangement able to produce.
  • the one scanning the entire width of the warp beam Sensor is able to reliably mark all markers capture.
  • the control signal of the sensor can be in technical be processed in a conventional manner, so that a human intervention is generally not required.
  • the Markers can be tailored to the required conditions for example, its windability and the ability to to influence the sensor at a predetermined relative position.
  • a preferred embodiment of the warping machine is if the marker is metallic and the sensor is metal sensitive.
  • the metal sensitive sensor speaks to the metallic one Markers reliably so that detection errors excluded are. Capacitive and inductive Use measuring methods through which simple designs of the sensor.
  • the marker is a plastic strip with embedded metal foil.
  • the metal foil can only meet the needs of the sensor or the detection process of the marker be tuned by the sensor.
  • the metal foil can especially be very small. Then you would be for the operation is difficult to see and to mark the trailing one Breaking less suitable.
  • the plastic strip advantageous to connect to the trailing fraction end can be matched. Such a The marker is particularly well visible and above all reusable.
  • the senor may be in the form of a strip Metal detector is designed.
  • a strip-shaped Formations can be positioned exactly so that the Response accuracy of the sensor to passing markers is equally good in all parts of the bar.
  • the strip-shaped Metal detector can in particular parallel to the warping drum are used and is used here to record passing Markers through remote recognition, especially with a coulter covering of the markers.
  • a warping machine with a strip-shaped Sensor can be designed so that the sensor over the warp beam width is divided into longitudinal sections, each only monitor the adjacent winding width.
  • a such a configuration is particularly advantageous if by dividing the sensor into longitudinal sections Monitoring of limited winding widths improves functionality of the sensor should be reached, especially if this is designed as a metal detector.
  • a further embodiment of the warping machine is in this regard possible that the sensor that when rearranging between the Warping drum and the threading machine guided thread band adjacent is arranged.
  • the space required Arrangement of the sensor available In this area between the warping drum and the rearing machine is the space required Arrangement of the sensor available. This can be arranged at the same time be that a marker without coulter coverage past the sensor.
  • the warping machine can also be designed so that the sensor of the warping drum is arranged adjacent. Out of this on the one hand there is an early passing of the Markers on the sensor, leading to a correspondingly early Generation of the control signal for stopping the rearrangement leads.
  • the rearrangement stop can be carried out in particular that the thread break does not run onto the warp beam. Especially such an arrangement of the sensor is suitable, however, a generation of the control signal to stop the rearrangement can already be achieved when a marker from the winding the warping drum is still covered.
  • the Umbäumstop can already predetermined with a thread coulter coverage Number of layers can be initiated.
  • the warping machine can be further developed that the marker is provided with a microchip which has predetermined winding data.
  • the winding data of the Microchips can be detected early by the sensor, which means that an individually adapted control of the warping machine is made possible. This speeds up the execution of a rearrangement stop.
  • the winding data can be taken from the microchip Warping machine will be communicated to the microchip during of a take-up stop during the warping, which warp thread length was measured and / or which one Warp thread length a subsequent thread break is expected so that the rearrangement process is carried out accordingly productively can be.
  • the warping system shown in Figure 2 essentially exists from a parallel gate 8 and a warping machine 12.
  • the warping machine 12 has a warping drum 6 with which a bevy of threads 11 is wound in strips, each be withdrawn from coils 16. Be of the coils 16 the threads 11 each by a not shown in Figure 2 Thread braking device arranged on levels Eyelet strips 10 out, which are located at the gate exit. From the eyelet strips 10, the threads 11 run through a Buchscher issued 17 and a thread guide, not shown on a support 18 to the warping drum 6.
  • a warping machine 5 is assigned to the warping drum 6, which has a warp beam 13 parallel to the warping drum 6.
  • the warp beam 13 is held up by two tree supports 18 and can be motor-driven in a manner not shown.
  • the rotating drive of the warp beam 13 is used for rearrangement the threads 11 from the warping drum 6 to the warp beam 13.
  • Das Rearranging is done to all wound on the warping drum 6 Bands, each due to the cone 6 'of the warping drum 6 have a parallelogram-like cross-sectional design, between side windows 13 'of the warp beam 13 into one Wind up the chain, which is then further processed.
  • FIG. 2 shows a side view of the warping machine in somewhat enlarged representation to explain the thread course when rearranging.
  • the warping drum 6 has been fully wound, and their threads 11 are over two deflecting rollers 19 on the Warp beam 13 wound between its side windows 13 '.
  • a sensor 4 is located between the deflecting rollers 19, which is formed like a strip and extends over the whole Warp beam width 15 extends so that this entire warp beam width the thread group of threads 11 during rearrangement can be monitored.
  • Figure 2 is parallel to Warping drum 6 below the deflection roller 19 near the drum Sensor 4 'shown, which is also over the entire Warp beam width 15 extends. So while the sensor 4 Threads 11 monitored between the guide rollers 19 so that the Threads close to the sensor 4 and thus free of thread coulter coverage are arranged, the on the winding of Warping drum 6 threads 11 from the sensor 4 from the Distance to be monitored.
  • the marker 14 is a plastic strip 1 with embedded metal foil 2.
  • the metal foil 2 also works the sensor 4 or 4 'together if the latter is sufficient comes close. This is particularly the case when the sensor is Metal detector is designed.
  • the winding process must be carried out so that the marker on Winding of the warping drum can be attached. To do this proceed in a conventional manner.
  • the winding process or Archipelago is interrupted by a winding stop as soon as there is a thread break message.
  • a thread break message is generated, for example, by a thread monitor.
  • everyone Thread is under the control of a thread monitor, which is attached to an eyelet 10, for example. Consequently Any thread break causes the Warping machine is stopped immediately.
  • the warping drum 6 is no longer driven, but braked and the broken one Thread 11 can either be repaired or at least marked become.
  • the warp thread end that is, the leading end of the break is wrapped in the wrap becomes. If the thread sheet is then rewound the warping drum 6 not possible up to the thread break point the thread end on the bobbin side, i.e. the trailing end Break end, marked with the marker 14 and then additional tape to be wound up.
  • each thread break in a computer 7 and saved each thread break warp thread length measured during winding up to thread breakage assigned. This can also be done in a conventional manner Operation of a memory key 3 of the computer 7 can be achieved. After the trailing end of the break with a marker 14 provided and thus added to the tape to be wound up the winding of the tape and other tapes carried out, possibly using additional markers 14 for corresponding thread breakages.
  • the warp thread lengths are then measured all markers before reaching these warp thread lengths each generated a pre-shutdown signal from the computer 7.
  • the tree-making machine 5 becomes one Creeper gear switched, runs with comparatively less Felling speed further.
