  • the invention relates to a method for operating a creel for a winding system according to the top handle of claim 1.
  • a method for operating a creel for a winding system according to the top handle of claim 1.
  • EP-A 319 477 describes a device for voltage compensation the threads on a creel became known which the thread brakes of the vertical rows of winding units can be loaded to different extents are.
  • the control rod is activated by drive motors, which receive control signals from a processor. Measured becomes the actual value of the thread tension of an entire thread assembly using a measuring roller shortly before winding. A consideration of the thread tension of individual threads or individual groups of threads are not possible.
  • DE-A 195 46 473 discloses a method for controlling Winding devices for thread coulters. There is also one here Tension measurement of the thread assembly shortly before winding up to by means not shown on the tension of the threads to act on the creel. With the help of a across the thread bandage mobile test car is the consecutive one Tension measurement of individual threads in a predetermined Time interval possible. A mean voltage value is formed from this, which is accordingly the common tensioning of all threads. With this procedure an individual regulation of Single threads or individual groups of threads practically not realized because not every thread is scanned at the same time can be.
  • DE-A 44 18 729 also relates to a device for regulating the thread tension in a creel.
  • This facility has one for each bobbin holder directly at the winding point Brake rotor on. Serves as a sensor for the thread tension a tensioning lever which is acted upon by the unwound thread becomes.
  • the individual control of the thread tension can thus be achieved through a general setting options of all thread tensioners can be overlaid.
  • a disadvantage of this device is that the control loop is limited to the winding unit. This is not suitable for an overhead creel.
  • the braking directly on the coil holder is also not Suitable for all work processes and the different barrel lengths the thread remains between the winding unit and the winding machine disregarded.
  • the method according to the invention can be used particularly advantageously each individual thread brake with a drive motor assigned to it activate. This is with today's inexpensive, miniaturized drives easily possible. Consequently For the first time, each individual thread on the creel can be individually regulated become.
  • the thread brakes with each thread group with the same barrel length to activate a drive motor.
  • the threads form of vertical rows (rails) of winding units per gate side one thread group each with the same length. It is therefore possible in a known manner, all thread brakes on one vertical row (rail) with a common gear link activate, with the drive motor in the area of the top or the lowest winding unit is arranged. So it is also possible A group-wise regulation for a desired thread group with one drive motor each.
  • Pretensioners are used to ensure trouble-free To ensure that the threads run off.
  • the pretensioners on a loop basis such as eyelet pretensioners, Crepe pretensioners, etc. can be used individually or in rails with a Drive motor can be adjusted to ensure optimal thread flow to obtain.
  • Threads or the thread groups gate length compensation
  • pretensioning devices can also be used for increasing the thread tension before entering the thread brakes be, the thread tension together with the thread brake is also regulated individually or in groups. These pretensioners can also be used as the only means be used for voltage distribution. There would be none additional thread brakes required, which is very inexpensive is.
  • thread brake as used here thus includes in the broadest sense also all prestressing devices.
  • the tensile force of the whole combined into a thread band the threads in the area in front of the winding point as the actual tape tension measured and compared with a Tension value and if all thread brakes are found when a deviation is found can be adjusted simultaneously in such a way that the actual strip tension value approximates the target tension.
  • This additional regulation of the tape tension is superimposed on the regulation of the thread tension described above, with all voltage changes between the thread tension sensors and the winding point become.
  • the invention also relates to a creel for a winding system, that in terms of device through the features in Claim 8 or 13 is characterized.
  • the thread tension can be adjusted individually on each individual thread or only on at least one thread of each thread group measured with the same barrel length using thread tension sensors become.
  • the measurement is advantageously carried out on threads that are not of deducted adjacent winding units of the corresponding rail become.
  • thread tension sensors There are basically different principles of thread tension sensors known. As particularly advantageous for the inventive However, sensors have proven to be useful for this purpose Force measuring device with a measuring element that responds to elongation have, the force occurring transversely to the thread is measurable on the deflected thread.
  • a thread tension sensor is described for example in DE-A 197 16 134, the content of which is hereby accepted in its entirety.
  • the sensor has a compact exterior and is relatively small insensitive to pollution.
  • the piezoresistive one Measuring bridge requires very little energy, which may be the case with the large number of sensors play a significant role plays. The measurement is also directly linear with the Movement of the sensor, with the possibility of measurement errors is reduced.
  • the thread tension sensor can also be functionally special simple way as thread monitor for thread running or thread break control insert the thread. Falls below or exceeds the thread tension of one or more threads the lower or upper control range, a warning signal is issued or the The winding system can be stopped automatically.
  • the functions of the thread tension sensor described can in addition to the use for thread tension control only as Monitoring function in a winding system for the entire thread group be used.
  • Stepper motors Be particularly advantageous as a drive motor for the thread brakes (Normal pressure thread brake e.g. disc brake, wrap thread brake, dynamic thread brake, etc.) or the mentioned Pretensioners (eyelet pretensioners, crepe pretensioners) Stepper motors used, which have a self-locking Act on the gearbox on the brake fluid.
  • the advantage of this Stepper motors is that they only operate during activation, but do not absorb energy in the holding phase. In order to energy consumption can be reduced significantly.
  • self-locking drive motor for example with a worm gear or a self-locking spindle drive ensures that a position approached by the stepper motor is held becomes.
  • the advantage of the stepper motor is that at any time the position of the thread brakes or the position of the pretensioners are known and can be calibrated.
  • Each winding unit can have at least one signal component, in particular a thread monitor for thread run or thread break control of the thread and / or an optical signaling means for identification assigned to the winding units or as a slip-on aid his.
  • the thread monitoring can be done according to various known Functional principles take place, e.g. the mechanical Falling pin principle, Hall sensors, optical monitoring means etc.
  • a signaling means to facilitate the assembly of a Coil gate has become known, for example, from EP-A-329 614.
  • FIGS. 1 and 2 there is a winding system 1, for example a warping system, from a creel 2 and one Winding machine (cone warping, slip, tree, etc.) 3.

  • the example shows a parallel gate with a left gate side LS and with a right gate side RS.
  • the same principle can also for any other type of gate, e.g. B. used in a V-gate become.
  • Fig. 2 shows the two thread groups with the longest run length L1 and the two thread groups with the shortest barrel length L2.
  • the thread tension sensors 9 either for each individual thread or for at least one thread arranged from the thread group with the same length (per rail).
  • the thread tension sensors can therefore also be in one area the winding point of the winding machine i.e. between reading and The warping blade can be arranged to bring the threads together. At corresponding miniaturization of the thread tension sensors can these are thus arranged so close together that in spite of the fact that each thread has already been brought together Thread can be applied. This also makes it unnecessary the previous band tension regulation because all changes the braking force was measured until just before the formation of the winding can be.
  • the threads After leaving the creel, the threads get into the Area of the winding machine 3, where it first has a reading sheet 10 happen in which the threads get their correct order.
  • the threads are then fed to the warping blade 11, in which they are brought together to form a thread 12 via a deflection and / or measuring roller 13 onto the roll 15 or to be wound onto the winding tree 14.
  • FIG. 3 shows, for example, how one unwound from a coil 4 Thread 5 two pretensioners on a loop basis and runs through a thread brake.
  • An eyelet pretensioner 16 and a crepe pretensioner (named after the one with a strong twist Crepe yarn) 17 have the task of to wind the thread-formed claw and as a chicane to act against swirl backflow and thus to avoid the formation of claws. At the same time, they limit the thread balloon, which forms when unwinding from the coil 4.
