Definitions

  • a controlled thread storage unit in front of the traversing devices along a thread path for winding bobbins, e.g. conical cross-wound bobbins.
  • These thread storage units are used to adapt the thread sagging that occurs when the bobbins are wound up to the constant thread delivery speed, for example of a spinning device or spinning cop take-off device.
  • the package is usually held during the winding process or the bobbin cycle in a pivoted creel of a traversing device downstream winding device and is usually driven by a friction roller via a frictional connection or individually.
  • the winding speed of the take-up package corresponds to the constant thread delivery speed, for example by the spinning device, depending on the diameter of the wound-up package.
  • the thread is defined across the width of the bobbin, in particular crosswise, by means of the traversing device. Due to the constant yarn delivery speed, the yarn periodically loosens, which is why, in order to maintain a desired yarn tension, there is a need to compensate for the slack in the course of the shortening of the working path of the yarn along the yarn travel path.
  • the object of the invention is to provide a thread storage unit which particularly reliably enables the thread tension to be maintained as constant as possible during the winding process.
  • the invention solves the problem by a thread storage unit with the features of claim 1, by a work station comprising such a thread storage unit according to the features of claim 8 and by a method for setting a thread tension at such a work station according to the features of claim 12.
  • Advantageous developments of the Invention are set out in the dependent claims.
  • the thread guide arm is freely rotatably mounted and has a magnetically acting first coupling element that is arranged at a distance from the pivot axis.
  • the drive unit has a second magnetic coupling element, which is arranged adjustably relative to the first coupling element and acts magnetically repulsively on the first coupling element.
  • the second magnetic coupling element is arranged on the drive unit so that it can be brought into operative connection with the first coupling element via the drive unit, wherein an adjustment of the second coupling element in the direction of the first coupling element causes a displacement of the first coupling element in the same direction and thus a pivoting of the thread guide arm.
  • the thread guide arm according to the present invention is a departure from previously known thread storage units, in which the thread guide arm is directly forced to rotate by a drive shaft of the drive unit, for example via a stationary bearing, on the drive shaft, and the force is consequently transmitted strictly by components touching one another along the power flow now freely rotatable, stored in particular on the drive shaft of the drive unit.
  • the rotational force generated by the drive shaft can be transmitted without contact to the thread guide arm using magnetically acting means.
  • the first and second coupling elements are aligned with one another in such a way that they exert a repelling magnetic effect on one another.
  • the first coupling element is displaced in accordance with the direction of movement of the second coupling element, which results in the connection of the first coupling element with the thread guide arm, it is pivoted about the pivot axis.
  • the thread guide arm is displaced about its pivot axis without contact via the drive unit, depending on the set position of the second coupling element arranged on the drive unit.
  • the thread guide arm By pivoting the thread guide arm about the pivot axis into the thread path, the thread guide arm creates a loop-like course of the thread in the area of the thread storage unit, with the thread guide arm preferably being able to engage with the thread in the area between two thread guide rollers or eyelets arranged along a thread path. to create a defined loop course.
  • a non-contact adjustment of the thread guide arm is effected by the drive unit via the two coupling elements. If there is excess thread during the winding process, which leads to a decrease in thread tension, then this is taken up in a loop between the preferably provided pair of thread-guiding rollers or eyelets and the thread-guiding arm.
  • the required thread length is released from the loop by moving the thread guide arm back, with the second coupling element being adjusted via the drive unit in such a way for this purpose that the thread guide arm is pivoted in an opposite direction pushing away the thread, with a reverse pivoting of the thread guide arm thereby the thread tension acting on the thread guide arm.
  • the thread guide arm thus follows the restoring movement of the second coupling element and releases the required thread length in a defined manner.
  • the thread storage unit thus makes it possible to keep the thread tension constant at a precise and high frequency via the freely rotatable thread guide arm, so that a winding process can also be carried out at particularly high winding speeds, with the production of both cylindrical and conical winding packages being particularly reliable.
  • the thread guide arm is adjusted in the direction of the thread or in the opposite direction without changing the distance between the first and second coupling element and thus without changing the magnetic spring force resulting from the distance between the two coupling elements.
  • An adjustment movement of the thread guide arm can be regulated in a preferred manner via a control system that activates the drive unit and a sensor unit that can be connected to the control system for transmitting detected sensor information.
  • the control system is preferably designed to evaluate and evaluate the transmitted sensor information and to activate the drive unit in a defined manner based on the result of the evaluation.
  • the control system can preferably include a control unit and an evaluation and evaluation unit. These units can be one and the same unit or different units. Two units can also be implemented with a single unit.
  • control system can also be part of the thread storage device or a separate component. Also, the arrangement of the control system can be freely selected. Thus, the control system can be provided in a work station, which includes the thread storage unit, in a central machine control and/or away from the textile machine. A redundant control by providing two such control systems that check or can check one another can also be possible.
  • the sensor unit that can be connected to the control system can preferably be used to detect the rotational movement and/or the position of the thread guide arm, whereby changes in the distance between the two coupling elements resulting from a change in the thread tension can also be determined via the sensor information recorded by the sensor unit. If the thread guide arm is in a displaced position in the direction of the second coupling element compared to the position set by the control system, ie the distance between the first coupling element and the second is reduced Coupling element, then the acting between the first and second coupling element magnetically generated spring force increases.
  • the thread storage unit thus makes it possible to keep the thread tension constant with a particularly precise and high frequency.
  • the configuration of the displacement of the second coupling element relative to the first coupling element by means of the drive unit can in principle take place in any manner.
  • linear drives are conceivable here, which linearly adjust the second coupling element in the direction of the first coupling element transversely to the pivot axis and thus bring about a displacement of the thread guide arm.
  • the second coupling element is arranged on a carrier that can be adjusted by means of the drive unit, in particular coaxially, about the pivot axis of the thread guide arm.
  • the second coupling element can be adjusted about the pivot axis of the thread guide arm, with the second coupling element being arranged on a carrier connected to the drive unit for this purpose.
  • the rotation of the carrier about the pivot axis of the thread guide arm makes it possible to use particularly space-saving rotary drives to adjust the second coupling element.
  • a rotation of the second coupling element which is particularly preferably arranged at the same distance from the pivot axis as the first coupling element, offers a particularly uniform and reliable adjustment, so that a particularly precise displacement of the thread guide arm can be carried out by the control system via a displacement of the carrier.
  • the arrangement of the first coupling element on the thread guide arm is basically free selectable. According to a particularly preferred embodiment of the invention, it is provided that the first coupling element is detachably attached to the thread guide arm and/or the second coupling element is detachably attached to the drive unit.
  • This embodiment of the invention makes it possible to easily change the first and/or second coupling element if necessary, so that adaptations to different production conditions, which may require magnetic effects that differ from one another, can be made in a simple manner. In addition, maintenance and repair work can be carried out particularly easily and quickly.
  • the drive unit for displacing the second coupling element, in particular the carrier can in principle be freely selected, with different motor drives being able to be used here.
  • the drive unit has an electric motor, in particular a stepper motor, with a drive shaft which is non-rotatably connected to the carrier and on which the thread guide arm is freely rotatably mounted.
  • the guide arm particularly preferably has a bearing unit, in particular a bushing element, at a free end, by means of which the thread guide arm can be placed on the free end of the drive shaft.
  • the bearing unit is designed to support the thread guide arm in a freely rotatable manner on the free end of the drive shaft, independently of a rotary movement of the drive shaft, ie torque-free.
  • the thread guide arm preferably has a thread guide section at its other free end, in particular a thread guide eyelet or roller, for contacting and guiding the thread. This allows the leverage of the yarn guide arm to be used to the maximum extent.
  • other arrangement locations selected as required, both of the bearing unit and of the thread guide section along the longitudinal axis of the thread guide arm are also conceivable.
  • the drive shaft serves to accommodate the thread guide arm in a freely rotatable manner, whereby a freely rotatable mounting or free rotary mobility is generally understood to mean a torque-free connection between the drive shaft and the thread guide arm, so that the drive shaft alone is used for pivoting, in particular for pivoting mounting, of the Thread guide arm is used on this, however transmits no torque.
  • a corresponding design of the thread storage unit also enables its particularly compact design, with it being ensured in a particularly reliable manner that a second coupling element arranged on the carrier can be adjusted around the drive shaft over the same circumference as the first coupling element, which is at a corresponding distance from the Axis of the drive shaft is arranged on the yarn guide arm.
  • first and/or second coupling element can be designed as electromagnets, the magnetic fields of which are aligned in such a way that they produce an effect that repels one another.
  • the electromagnets can be controlled via the control system, so that different magnetic fields can be generated via them if necessary, so that the repulsion effect can be set and, in particular, regulated via the corresponding control system.
  • the first coupling element and the second coupling element are designed as permanent magnets.
  • the use of permanent magnets as coupling elements, which are arranged in a correspondingly aligned manner on the thread guide arm and the carrier, represents a particularly simple, low-maintenance and cost-effective way of providing a magnetic repulsion effect.
  • the desired repulsion effect can be determined by selecting the permanent magnets.
  • connection of the carrier to the drive unit in particular to a preferably provided drive shaft of an electric motor, can be established by simple flange connections.
  • the carrier is arranged on a coupling disk which is arranged coaxially to the drive shaft and is connected to the drive shaft in a rotationally fixed manner.

  • the thread storage unit can have further magnetically or mechanically spring-acting coupling elements, which are directed counter to the direction of magnetic force action of the first and second coupling element and are designed to reset the thread guide arm as required against the direction of deflection by the first and second coupling element.
