Definitions

  • the present invention relates to thread laying for a winding device a thread on a bobbin, with a thread guide attached to a thread guide slider, and with a flexible, motor-driven traversing element acting on the thread guide glider, which is guided over rollers.
  • Thread laying of this type is described in EP-A-0 453 622 and in EP-A-0 829 444, in which the traversing element is formed by a wire rope, a string or a belt is.
  • the traversing element is driven by two pulleys and a motor Driving wheel guided, which span an isosceles triangle. The dimensions of this The length of the thread is determined by the desired maximum bobbin length and by the Determines the diameter of the pulleys.
  • a thread laying of the type mentioned at the outset is now to be specified by the invention, which is characterized by a minimal overall length and therefore simple afterwards can be fitted into existing machines.
  • This object is achieved in that the thread guide glider and the Traversing element leading roles in different, spaced planes are arranged, the distance between the levels being chosen so that the rollers outside the path of movement of the thread guide glider.
  • the maximum stroke of the thread guide increases by approximately twice the radius of the rollers. Depending on the roll diameter, this results in one with the same stroke Reduction of the installation length by, for example, about 40 mm.
  • a third preferred embodiment of the thread laying according to the invention is thereby characterized in that the thread guide slider can be moved back and forth on a holding plate is stored, and that the rollers mentioned are also mounted on the holding plate.
  • a further preferred embodiment of the thread laying according to the invention is thereby characterized in that the thread guide glider, the rollers and the traversing element the holding plate can be assembled into a structural unit.
  • Pre-assembled thread laying is preferred can be attached to the intended textile machine so that the thread guide glider Roll and the traversing element to the front covered by the holding plate and to the rear are accessible towards the machine.
  • 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 for laying a thread, which is drawn off 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 traversing movement.
  • the thread guide 5 is movable back and forth on a guide 6 in a rail-like or groove-like manner Thread guide glider 7 attached to which a traversing element 8 engages.
  • This is designed as a flexible and rigid in the traversing direction 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 is attached at both ends to the drive wheel 13 and wraps around it with several Turns.
  • 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 to the load formed from thread guide 5, thread guide glider 7, thread and traversing element 8 adjusted that an ideal efficiency results.
  • the motor 12 is a sensor (not shown) to detect the rotational position of the driving wheel 13 and thus the traversing position of the thread guide 5 assigned. Regarding this sensor and its interaction with the control of engine 12, reference is made to EP-A-0 829 444.
  • the central region of the holding plate 9 which supports the motor 12 and the drive wheel 13 is as resilient clamping plate 9 formed, which via bending beams with the edge region of the holding plate 9 (see 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 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 increase 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 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 in the delay phase, both a loosening of one and an overextension of the other Run of the traversing element.
  • the reference numeral H 1 denotes the normal distance between the axes of the deflection rollers 10, 11 and the axis of the drive wheel 13 and with H 2 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.
  • Fig. 3 shows a view of the thread laying 1 'of Fig. 2 seen from the left, the servo motor 12 (Fig. 2) is not shown.
  • the thread to be laid is labeled F, the thread path goes from left to right through the thread guide 5 to the bobbin 4 (Fig. 1).
  • the preferred thread guide 5 formed by a ceramic eyelet is on the thread guide slider 7 a support arm 17 attached. It can be seen that the holding plate 15 as a profile rail with two parallel rail or groove-like guides 18 and 19 is formed. In leadership 18, which extends over the entire length of the holding plate 15, the thread guide slider 7 out and moved here.
  • the guide 19 serves to receive storage means 20 for the Rolls 10 ', 11'.
  • the bearing means 20 are in the guide 19 in the stroke direction movable and fixable. Because the stroke is only adjusted over a certain range is, the guide 19 need not over the entire length of the holding plate 15 but only to extend over a certain area at their left and right ends.
  • the carrier arm 17 projects from the thread guide slider 7 into the plane of the rollers 10, 11 '.
  • the drive cable forming the traversing element 8 extends along a common straight line Line from the rollers 10 ', 11' to the thread guide slider 7 and is attached to the support arm 17.
  • the illustrated arrangement of the thread guide slider 7 and the rollers in different levels can also be used in the thread laying 1 shown in FIG. 1, then the holding plate 9 is used with a correspondingly greater overall height would. It is essential in both cases that the rollers 10, 11 and the drive wheel 13 (Fig. 1) or the rollers 10 'and 11' (Fig. 2) together with the thread guide slider 7 and the traversing element 8 are assembled on the holding plate 9 or 15 so that the thread laying 1 or 1 'is available as a compact unit, which is simple and quick on the provided machine can be assembled.
  • the reference numeral 21 denotes a machine wall in FIG. 3 on which the thread laying 1 'is mounted. As shown, there is an angled one on the machine wall 21 Carrier plate 22 attached to which the thread laying 1 'is screwed. against the machine the carrier plate 22 is covered by a cover 23. Through the illustrated The arrangement is thread laying 1 'towards the front, towards the viewer, through the holding plate 15 fully covered. The rollers 10 ', 11', the traversing element 8 and the thread guide slider 7 lie below the holding plate 15, which not only increases safety but also also the cleaning of the thread laying 1 ', for example by compressed air from the machine forth, much relieved.
