Definitions

  • the present invention relates to thread laying for a winding device of a thread on a bobbin, with a thread guide, which with a running over deflection rollers, flexible, motor-driven traversing element is connected and a traversing movement runs in the longitudinal direction of the coil, and with a biasing element to compensate for Voltage fluctuations of the traversing element, one of the deflection rollers as a drive wheel for formed the drive of the traversing element and the height of the thread laying in essentially determined by the diameter of the deflection rollers and the thread guide a sliding member mounted in a guide is attached.
  • the invention is now a thread laying of the type mentioned with minimal Construction height can be specified, which is simply retrospectively due to its low construction height existing machines can be fitted.
  • this object is achieved in that the roles mentioned are arranged in this way are that the plane spanned by the traversing element by a narrow, in the longitudinal direction of the coil to be manufactured is formed and that said Rollers and said guide on a common holding plate of the shape of a narrow strip are arranged.
  • the overall height of the thread laying essentially depends on the diameter of the deflection rollers reduced and is therefore only a fraction of the previous height. This will make the Height of thread laying so low that it can be retrofitted in many machines can be.
  • DE-A-196 44 911 describes a device for winding a thread, in which the traversing device has a belt driven in one direction and one between the Both strands of the belt can be moved back and forth and non-positively with straight guides has connectable carriage. The carriage is driven across the belt magnetically, so this device does not have high traversing speeds and is not precise Positioning the thread guide allows.
  • a third preferred embodiment of the thread laying according to the invention is thereby characterized in that the deflecting roller forming the prestressing member is spring-mounted.
  • a further preferred embodiment of the thread laying according to the invention is thereby characterized in that the deflection roller forming the pretensioning member by means of a linear guide and spring or is mounted by means of an integral spring.
  • the winding unit essentially consists of a spindle 2 for receiving and holding a coil sleeve 3, on which a coil 4, for example a cheese, is wound and from thread laying 1.
  • the latter is used to lay a thread, which is withdrawn from a supply spool by a delivery unit, not shown.
  • the coil 2 is either directly driven or lies along a surface line on a freely rotatable roller on a suitable carrier part of the textile machine in question (not shown) is mounted.
  • the thread laying 1, which is used to produce the desired winding, contains the most important element is a thread guide 5, which oscillates along the axis A of the bobbin 4 Executes oscillating movement.
  • the thread guide 5 is movable back and forth on a guide 6 in a rail-like or groove-like manner Fixed sliding element 7, on which a traversing element 8 engages.
  • This is as flexible and trained in the traversing direction rigid member for the transmission of tensile forces and for example by a string, a wire, a metal rope, a flat, toothed or V-belt, a metal band, a chain or the like.
  • the thread laying 1 is on a holding plate 9 attached, which in turn is mounted on the machine.
  • the traversing element 8 runs About two rigidly mounted guide rollers 9 and 11 to one of one Servo motor 12, preferably a stepper motor, driven drive wheel 13.
  • the traversing element 8 wraps around the drive wheel 13 with several turns and is at both ends on this attached.
  • the drive wheel 13 When driving the drive wheel 13, depending on the direction of rotation of the thread guide 5 in the direction moved to one or the other pulley 10 or 11.
  • the distance between the Deflection rollers 10 and 11 give the maximum possible stroke of the thread guide 5 during its traversing movement on.
  • the drive wheel 13 is based on the torque characteristic of the motor 12 and adapted to the load formed from thread guide 5, sliding element 7, thread and traversing element 8, that an ideal efficiency results.
  • the motor 12 is a sensor (not shown) for detecting the rotational position of the driving wheel 13 and thus assigned to the traversing position of the thread guide 5. Regarding this sensor and its interaction with the control of the engine 12 is disclosed in EP-A-0 829 444 directed.
  • the central region of the holding plate 9 which supports the motor 12 and the drive wheel 13 is as resilient clamping plate 9 is formed, which via bending beams with the edge region of the holding plate 9 is connected (see also EP-A-0 829 444).
  • the resilient effect of the clamping plate 14 is used to make dynamic changes, preferably formed by a steel cable To compensate for traversing element 8 in the area of the movement reversal points. If the thread guide 5 reaches a reversal point, then the two behave towards the thread guide subsequent dreams of the traversing element 8 differently, in the braking phase the forward strand relaxed in the direction of movement and that in the direction of movement rear strand stretched and in the acceleration phase the front strand in the direction of movement The traverse of the traversing element is stretched and the rear is loosened.
  • This dynamic behavior of the traversing element 8 limits the positioning accuracy of the thread guide 5 at a given acceleration or deceleration and thus the Traversing speed of the thread guide 5 with a given positioning accuracy. Since the requirements for the positioning accuracy of the thread guide are already in the case of packages are very high and would still rise for windings according to any winding laws, that would mentioned dynamic behavior of the traversing element 8, the traversing speed and so that the winding speed is noticeably limited.
  • the drive wheel 13 acts on the traversing element 8 like a pretensioner that presses laterally against the traversing element and fluctuations balances out its tensions. Since each strand of the traversing element 8 from the thread guide 5 is guided to the drive wheel 13, this resilient biasing member acts simultaneously both dreams of the traversing element 8 and thereby prevents in the acceleration and in the delay phase, both a loosening of one and an overextension of the other Run of the traversing element.
  • H 1 denotes the normal distance between the axes of the deflection rollers 10, 11 and the axis of the drive wheel 13
  • H 2 denotes the distance between the axes of the deflection rollers 10, 11 and the lower edge of the holding plate 9.
  • the latter distance is referred to as the overall height or width of the thread laying 1, which is essentially due to the height on the base line of the isosceles triangle spanned by the traversing element 8 ( ⁇ H 1 ) and by the distance between the axis of the drive wheel 13 and the lower edge of the Holding plate 9 is determined.
  • Fig. 2 shows a view of an embodiment of a thread laying 1 'whose overall height is only about 20% of the overall height of the thread laying 1 of Fig. 1.
  • one of the two deflection rollers as shown the deflection roller 10 ', takes over the function of the drive wheel, so that the plane spanned by the traversing element 8 no longer has the shape of a triangle but the shape of a narrow band. Accordingly, the distance H 1 becomes zero.
  • the distance H 2 is also significantly reduced because, in addition to the elimination of H 1 , the clamping plate 14 (FIG. 1) and its storage have also been eliminated.
  • the servo motor 12 is arranged behind the deflection roller 10 'and that with the reference number Holding plate designated 15 has a correspondingly smaller height or width than the holding plate 9 of thread laying 1 of Fig. 1.
  • the overall height of thread laying 1 ' is essentially determined by the diameter of the deflection rollers 10 ', 11' and is thereby reduced to one Fraction of the overall height of the thread laying 1 (Fig. 1) reduced. This also leads to a corresponding one Material and cost reduction.
  • the other deflection roller 11 ' is designed as a pretensioning element, which results in further simplification and cost reduction.
  • Fig. 2 it is indicated that the guide roller 11 'in a linear guide against the force of the guide roller 11' after outside pressing spring 16 is mounted.
