- a quality matrix is created, in for example, the diameter deviation in percent and the error length is entered in millimeters.
- this Matrix is set the desired degree of purification and the machine or the job specified.
- the receives required values for determining the error length the cleaner for example by detecting the current Surface speed or the speed of the Drive roller, which by means of friction, the cheese in Rotation offset. Jobs with such Cleaners are, for example, from the CH 635 300 A5, from the DE 29 18 740 C2, from DE 39 11 505 A1 or the generic DE 196 40 184 A1 known.
- the CH 669 779 A5 describes the length measurement of the current Yarns on spools producing cross-wound bobbins.
- the Length measurement is carried out by means of an optical Correlator.
- the length of the wound yarn are determined as accurately as possible to Example in the weaving preparation the rewinding of Residual coils or waste remaining on the coils To reduce or completely avoid yarn residues.
- the yarn becomes for example, from a spinning cop to that of a Reel wound Reel wound reel.
- Such Grooved drum is also called a drive roller with reverse thread designated.
- a probe with built-in knife and a Control unit are used for electronic yarn cleaning.
- the Length measuring device consists of a further probe, which contains an optical device and a preamplifier and from a counting and display unit, which all others Contains circuits. From the yarn cleaner or even one mechanical thread feeler as well as of the drive device of Cheese, the length measuring device receives the information that actually a yarn is spooled. This should be avoided be that in the Umspulpausen or at Thread breaks measured values are recorded, the lead to erroneous results.
- the counting unit receives Signals from the length measuring device. After reaching the Target length of the wound on the cross-wound yarn is From the counting unit a signal is given to the yarn cleaner and the thread is severed by the built-in knife. One further data exchange between the Length measuring device and the yarn cleaner does not take place.
- Another device for measuring the speed of Threads on a winding device shows the DE 42 25 842 A1.
- the winding device is used to produce cheeses, wherein the rotation of the cheese by means of a frictional action of a drive roller is generated.
- a runtime correlator circuit with two at a fixed distance in the direction of movement of the running textile thread successively arranged measuring points, where contact is measured, and another Signalers are connected to each other.
- the signaler is designed as a pickup, the pulses of one with the Drive roller of the cross-wound bobbin connected.
- the Density of the pulse sequence is a measure of the Circumferential speed of known in their diameter Drive roller and thus also approximately for the speed of the running thread.
- Runtime correlator determined speed can via a Integrator directly for cumulative run length determination of a textile thread.
- the generic DE 196 40 184 A1 describes the complete cleaning both long and short Garnwhere at the winding units of a winder. This will be after the occurrence of a yarn defect, the length of the yarn faulty thread between the time of occurrence the error and the time of the thread cut determined. to Elimination of the faulty thread piece becomes a suction tube positioned in front of the package. The thread end is unwound, the entry of the thread by means of a in the Suction tube arranged thread end sensor detected and the unwound from the package and in the suction pipe incoming thread length determined.
- the unwinding process will stopped if, based on the determined thread length one such thread length has been sucked into the suction pipe, that during subsequent insertion of the bobbin-side thread in the yarn end connecting device since the occurrence of Garnschreib still wound thread length outside the Thread end connecting device for separating remains.
- the Quality control of the yarn is carried out by the measuring head of a Cleaner.
- a yarn cleaning device the so is set up that the means for determining the Longitudinal extension of a yarn error one contactless working measuring head with two in the direction of movement of current thread successively arranged measuring points and a delay correlator for evaluating the temporal sequence of the detected measured values has increased the accuracy of the measured error length is significant.
- a higher measuring reliability can also be applied to one "Safety margin" when determining the Cleaning limits in the quality matrix whole or partially waived.
- Such a surcharge exists For example, in a shortening of each as inadmissible predetermined error length to ensure that despite Occurrence of measurement inaccuracy a certain invalid Error is still detected and cut out.
- the non-contact measuring head with two in the direction of movement of the current thread in a row having arranged measuring points and a Runtime correlator for evaluating the time sequence of has detected measured values, it may be in the two Yarn sensors arranged at the two one behind the other Measuring points are used to non-contact Sensors that act, for example, on optical or capacitive base work.
- the yarn sensors detect one stochastic function of the transverse dimension of the running thread, where the variations of the transverse dimension mass, volume or Diameter variations can be.
- the measuring head designed so that the yarn sensors the Detect transverse dimension of the running thread, the Transverse dimension of the current thread representing signals on the one hand for a highly accurate determination of Garn breeding, and on the other hand advantageous for a Quality control of the yarn can be used.
- This also has the advantage that the transverse dimension of the current thread and the yarn speeds are measured at the same point and thus no caused by different measuring locations Falsifications of the measurement result may occur.
- One so far for the yarn cleaning usual separate cleaner measuring head eliminated. By eliminating the cleaner measuring head at each Job can be in multi-site textile machines, such as Spooling machines or spinning-winding machines, considerable Achieve savings or cost reductions.
- a further increase in measurement reliability achieved in that the yarn cleaning device so is set up as a signal to monitor the Transverse dimension of the current thread in each case a third signal as arithmetic mean of the respective measured values of the two measuring points is formed.
- Leave with a yarn cleaning device according to the invention advantageously an increase in the accuracy of measurement and the measuring reliability, a quality improvement of the yarn as well as cost savings and productivity gains in the Achieve textile machine.
- the drive roller 7 gives the cheese 8 by means Frictional action a rotational movement.
- the cheese 8 is supported by a coil holder 9, which in a rotary joint 10th pivotable in the machine frame 11 partially shown is stored.
- the thread 1 is subject to a continuous Quality monitoring. This is done by means of the Cleaner measuring head 4 the diameter of the running thread 1 measured. For the diameter or thickness measurement of the thread 1 is a known optical Sensor device used.
- the measuring head 6 has two in the direction of movement of the current Thread 1 consecutively fixed measuring points with each a yarn sensor 12, 13. The measured values of the yarn sensors 12, 13 are evaluated via a delay correlator 14 and the Thread speed determined. About an integrator is the Thread speed for cumulative run length determination of Thread evaluated.
- An angle sensor 15 outputs signals proportional to Thread speed off.
- a flywheel 17 is arranged, whose individual poles when moving past the angle sensor 15th be registered.
- the number of pulses is counted and via the control device 18 to the delay correlator 14 for Range specification for the correct locking of the control loop fed.
- the control device 18 comprises an evaluation and Memory module.
- the control device 18 has a module to the store specified yarn length and the specified Yarn length and the cumulated yarn length together to compare. If the cumulated yarn length reaches the predetermined value, generates the controller 18 a Signal with which the cutting device 5 is activated and the Thread 1 is severed. The winding process is terminated, the full cross-wound bobbin 8 transported away and after inserting a not shown empty sleeve a new winding process started.
- the length measurement described allows highly accurate compliance the predetermined thread length, on the cheese 8 should be wound up.
- Figure 2 shows a winding unit with an alternative Formation of the yarn cleaning device according to the invention, which largely equals the winding unit of FIG. in the Difference to the winding unit of Figure 1, this winding unit however, no separate detergent measuring head.
- the yarn sensor 12 detects the thread thickness.
- the yarn sensor 12 is part of it one known per se and therefore not in detail shown optical measuring path. Becomes an invalid Thickness deviation of the thread 1 detected, is about the Linkage with the controller 18, the length of the Garnmount determined. Carrying out a cleaner cut as well as end and beginning of the winding process are at the Spool of Figure 2 analogous to that described in Figure 1 above Process completed.
- the measured values of the yarn 1 representing the thread thickness of the thread 1 Garnsensors 12 are on the one hand as a thickness value for the Quality control evaluated and used in conjunction with the measured values of the yarn sensor 12 of the speed relationship Yarn length measurement.
- the measured values for Detection of the thread thickness of both the yarn sensor 12 as well the yarn sensor 13, which is like the yarn sensor 12, fed to the controller 18 and in the Control device 18 from each of the same place of the thread measured values each have a third signal as Arithmetic mean of the two measured values formed. With This signal representing the thread thickness becomes the Measurement reliability increased.
