  • These known devices have a device for detecting the rotational speed of the cheese, a device for calculating the current diameter of the cheese and a storage device with a predetermined thread tension program. In devices equipped in this way, the thread tensioner is controlled during the bobbin travel so that the thread tension gradually decreases as the diameter of the package increases.
  • a device is also known from EP 0 350 081 A1, at which the winding speed of the winding units in Controlled depending on the remaining thread length of the supply spools becomes.
  • the facilities also each have one Thread tensioner on during the winding process if necessary can be controlled in a defined manner by the winding unit computer.
  • thread tensioners are have a rotatable brake actuator arrangement, wherein one of the brake actuators axially by means of a moving coil has been known for a long time.

  • the service unit can via the central control unit and the winding unit computer the winding drive of each winding unit like this control that during the change process Cheese / empty tube the thread guide drum with a compared to the 'normal' winding process, i.e. reduced peripheral speed rotates.
  • DE 42 21 504 A1 describes an automatic winder, the workstations of which are connected to a service vehicle via a bus line. If there is a need for operation at one of the workplaces, the workstation in question sets an optical signal which is recognized by the service vehicle patrolling in front of the workplaces and which is confirmed at the workstation by a light signal to the workstation. This light signal activates the relevant work station, so that work commands, for example, turning the drive roller backwards, blowing off work stations or the like, can then be set down from the service vehicle via the bus line.

That is to say, in particular in the case of the bobbin handling measures to be carried out in connection with the bobbin / empty tube change process, the thread tension required in each case can be optimally adapted by means of the thread tensioner arranged at the winding point in accordance with parameters specified by the control computer of the service unit. It is possible to choose smaller settings during the changing process than those that are common during the winding process.
  • the thread tensioner can precisely control the winding unit via the machine bus it is not necessary for the service unit to operate during of the change process to maintain an exact thread tension can have their own thread tensioning device.
  • the control computer of the Service units can be specified via the thread tensioner on the Thread attachable thread tension values according to the respective coil handling measures of the service unit are individually adaptable.
  • the thread tension will consequently also automatically set optimally during the change process and depends, for example, on whether the package is a Head reserve in the form of a head reserve Tendon or a head reserve winding in the form of one on the So-called top-cone winding applied to the sleeve tip should receive. Also when creating the foot reserve winding a special, optimal one is automatically placed on the empty tube Thread tension set.
  • the parameters required to set the thread tensioner can from the control computer of the service unit either, as described in claim 4, in absolute values be specified or, as set out in claim 5, as Percentage deviation from adjustable setpoints.
  • a specification of the setting parameters as a percentage deviation of setpoints is particularly advantageous because of these Way also during the winding process Setting the thread tensioner to the currently processed Yarn, for example in terms of tear strength, is possible.

  • the service unit 23 is movably mounted with carriages 24, 25 on machine-long tracks 26, 27 which are arranged above the winding units 2.
  • the service unit 23 not only ensures that the cross-wound bobbins 11 finished on the winding units are rolled out onto the cross-wound bobbin transport device 21, but it also independently changes an empty tube 28 into the bobbin frame of the winding unit 2 in question.
  • the service unit 23 preferably takes the empty tube 28 from an empty tube magazine 22 that is provided in the winding unit.
  • FIG. 2 Of the relatively extensive and generally known bobbin and tube transport system 3, only the machine-long bobbin feed path 4, the reversing path 5 running behind the bobbin units 2, one of the transverse transport lines 6 leading to the bobbin units 2 and the tube return path 7 are shown in FIG. 2.
  • the individual winding units 2 have, as is known and therefore only hinted at, various devices which ensure proper operation of these work stations.
  • 30 is the thread running from the spinning cop 9 to the cheese 11
  • 12 is a suction nozzle and 42 is a gripper tube.
  • a splicing device has the reference number 13
  • a thread tensioning device has the reference number 14.
  • such winding units have a thread cleaner 15 with a thread cutting device and a paraffinizing device 16.

That is, the package changer 23 provides ensure that cross-wound bobbins 11 which have a predetermined diameter have reached, on the bobbin transport device 21st be carried out and that subsequently from the Empty sleeve magazine 22 each have an empty sleeve 28 in the Coil frame 18 is replaced.
  • FIG. 2 shows some of the handling elements of the service unit 23 required in the course of the cross-wound / empty tube change process, which are: frame opener 29, frame lifter 32, coil guide device 33 and sleeve feeder 31.
  • frame opener 29, frame lifter 32, coil guide device 33 and sleeve feeder 31 For the sake of clarity, the illustration of further handling elements of such cross-wound bobbin changers has been omitted in this figure.
  • the devices for creating a head reserve winding and the foot reserve winding are not shown, for example.
  • the winding unit computer 39 has a plurality of so-called drivers 43, which are each connected to downstream functional elements via command lines.
  • the output stage 44 of the thread tensioner 14 is connected, for example, via a command line 41 to one of the drivers 43 of the winding station computer 39.
  • the known and proven thread tensioner 14 has, as usual, a turntable arrangement 47, 48.
  • the turntable 47 can be acted upon in rotation by a drive 49, while the turntable 48 can be axially displaced by a moving coil 45, 46.
  • the thread 30 drawn off from a spinning cop 9, which is subsequently wound up into a cross-wound bobbin 11, is clamped in a defined manner.
  • the thread tension effective on the thread 30 can be adjusted via the degree of clamping of the brake adjuster of the thread tensioner. This means that the thread tension in these known thread tensioners is adjusted by energizing the moving coil 45, 46 accordingly.
  • a Cheese 11 their predetermined diameter or their has reached the specified thread length is via the Thread cutting device 16 first separated the thread 30 and the cheese through a (not shown) Coil lifting device lifted from the drive drum.

  • the thread tension values, which are maintained by the thread tensioner 14 during the change process, are dependent on the respective bobbin handling measures or on the selected configuration of the bobbin 11.
  • the thread 30 held in the thread lifter has to be wound onto the sleeve tip with a different thread tension than if the package has a thread end reserve in the form of a tendon.
  • the thread 30 held in the thread lifter is, for example, laid in the direction of the sleeve tip by means of a corresponding working element (not shown) and the cheese is slowly rotated in the winding direction.
  • the thread tension is preferably slightly higher than the thread tension on the last section of the bobbin travel.
  • the thread is briefly brought down from the outer surface of the cross-wound bobbin after the bobbin travel and immediately returned to the outer surface. In this case, it is advantageous to work with a significantly reduced thread tension.
