Definitions

  • the present invention relates to a device for winding a thread on a bobbin, with a thread guide which is connected to a string running via a motor-driven drive wheel and deflection rollers and carries out a traversing movement in the longitudinal direction of the bobbin, and with a sensor for monitoring which acts as a position transmitter the traversing movement of the thread guide.
  • the deflection rollers and the string are arranged rigidly on a common carrier plate. Each time the thread guide and thus the string reverses, one of the two strings of the string running from the thread guide via the deflection rollers to the drive wheel is tensioned and the other is loosened, which impairs the accuracy of the positioning of the thread guide and limits the traversing speed.
  • the invention is now to provide a winding device in which the above-mentioned dynamic changes in the string no longer occur in the area of the reversal points of movement, so that a very high traversing speed and also a very high positioning accuracy of the thread guide are achieved.
  • this object is achieved in that the string is guided via a prestressing element which is resiliently mounted transversely to the latter in order to compensate for fluctuations in tension.
  • a first preferred embodiment of the winding device according to the invention is characterized in that the deflection rollers are fixedly mounted on a common carrier and that the pretensioning element is formed by the drive wheel.
  • a second preferred embodiment of the winding device according to the invention is characterized in that the drive wheel is mounted on a tongue-like tab which is supported by bending beams.
  • the design of the drive wheel as a pretensioning member not only has the advantage that no additional element is required for the pretensioning member, but also enables the dynamic changes in the string to be optimally compensated for. The latter is because both strings of the string, the one running over the one and the other pulley, wrap around the driving wheel so that it can act on both dreams at the same time.
  • the mounting of the drive wheel on the tongue-like tab connected to the carrier via bending carriers has the advantage that an optimal dynamic characteristic of the prestressing member can be achieved for the respective machine configuration by suitable dimensioning and design of the bending carriers.
  • a third preferred embodiment is characterized in that a base plate which is connected to the support, preferably screwed, is provided, on which the bending supports engage, and that the tab is supported on one edge by the bending supports and is exposed on the other edges.
  • a fourth preferred embodiment is characterized in that the base plate has two mutually encompassing, mutually directed U-shaped recesses, of which the inner part separates the flap from the bending supports and the outer part separates the bending supports from the base plate, and that the bending supports between the longitudinal legs of the Recesses run from the tab to the base plate.
  • a further preferred embodiment of the winding device according to the invention is characterized in that the sensor for the traversing movement of the thread guide monitors a rotating member coupled to the thread guide and scans the markings made thereon.
  • the rotating member is preferably formed by the drive wheel or by a disk rigidly connected to the drive wheel.
  • the design of the sensor according to the invention has the advantage that it always knows the exact position of the thread guide based on the number of scanned markings, so that the drive motor can always be controlled by a controller to the speed corresponding to the respective position. As a result, the power of the drive motor formed by a stepper motor can be used almost completely.
  • the bobbin shown in Fig. 1 consists essentially of a motor-driven spindle 1 for receiving and holding a bobbin tube 2, on which a bobbin, for example a bobbin 3, is wound, and from a device 4 for laying a thread F through a delivery unit, not shown, is withdrawn from a supply spool.
  • the cheese 1 lies along a surface line on a freely rotatable roller 5, which is mounted on a suitable carrier part 6 of the winding machine.
  • the thread laying 4, which is used to produce the desired winding contains, as the most important element, a thread guide 7 which executes an oscillating oscillating movement along the axis of the bobbin 3, that is to say perpendicular to the plane of the drawing.
  • the thread guide 7 is fastened on a string 8, whereby a string, a wire, a thin metal cable or a belt is also to be understood.
  • the string 8 runs over two deflection rollers 9 and 10 rigidly mounted on the carrier part 6 to one of one Motor 11, preferably a stepper motor, driven drive wheel 12 and wraps around it with several turns.
  • the thread guide 7 is moved in the direction of one or the other deflection roller 9 or 10.
  • the distance between the deflection rollers 9 and 10 indicates the maximum possible stroke of the thread guide 7 during its traversing movement.
  • the drive wheel 12 is adapted to the torque characteristics of the motor 11 and to the load formed from the thread guide 7, thread F and string 8 in such a way that an ideal efficiency results.
  • a sensor 13 for detecting the rotational position of the drive wheel 12 and thus the traversing position of the thread guide 7 is assigned to the motor 11.
  • the sensor 13 is a photoelectric sensor consisting of a transmitting and a receiving diode, which senses the movement of a disk (not shown) rigidly connected to the drive wheel 12.
  • the disk is provided with suitable optically scannable markings, for example with holes or slots arranged along a circle.
  • the sensor signal is fed to a controller 14 which checks whether the motor 11 is running at the speed provided for the respective position of the thread guide 7. In the event of deviations between the actual value and the target value, the control stage 14 emits a corresponding control signal to the motor 11.
  • the number of markings on the disk and their dimension are selected such that approximately 1500 positions of the thread guide 7 can be checked per stroke of the thread guide 7.
  • the carrier part 6 has in the area of the thread laying 4 an approximately rectangular opening 15, which is covered against the thread F by a base plate 16.
  • the base plate 16 which is shown in more detail in FIG. 3, has on its longitudinal edges a plurality of bores 17 serving to receive fastening screws and is screwed to the edge of the opening 15 in the region of these bores.
  • Two further bores, provided with the reference symbol 18, serve to pass through the axes of the deflecting rollers 9 and 10 which are mounted in the carrier part 6.
  • the base plate 16 consists, as shown, of a strip-like edge region 19 and of a tongue-like tab 20 which is connected at one transverse edge to the edge region 19 of the base plate 16 and the other edges of which are exposed.
  • the connection between the tab 20 and the edge area 19 takes place via two bending beams 21, which engage the above-mentioned transverse edge of the tab 20 and, at a distance from their longitudinal edges and parallel to them, are guided in the gap between the tab 20 and the edge area 19 to the opposite transverse edge of the edge area 19 .
  • This arrangement looks as if the two bending supports 21 separate two, as it were, inserted, mutually directed, U-shaped recesses 25, 26, of which the inner recess 25 the tab 20 from the bending supports 21 and the outer recess 26 the bending supports 21 separates from the base plate 16.
  • the tab 20 of the base plate 16 is thus resiliently mounted on the edge region 19 and can be adjusted by the action of appropriate forces, both in the direction perpendicular to the plane of the drawing and transversely to the longitudinal edges of the base plate 16.
  • the tab 20 has a bore 22, which is provided for the rotationally secure reception of a corresponding part of the motor 11 (FIG. 1).
  • the motor 11 is fastened to the rear of the tab 20, so that the drive wheel 12 protrudes from the bore 22 at the front.
  • the part of the motor 11 held in the bore 22 is designed such that the best possible heat transfer takes place from the motor 11 to the bracket 20.
  • the tab 20 not only acts as a resilient carrier of the drive wheel 12, but also as a cooling surface for the motor 11.
  • the resilient action of the tab 20 is used to compensate for dynamic changes in the string 8, which is preferably formed by a steel cable, in the area of the movement reversal points.
  • the two strings of the string 8 adjoining the thread guide behave differently, by loosening the front strand in the direction of movement and stretching the strand in the direction of movement, and stretching the strand in the direction of acceleration in the acceleration phase the string is stretched and the back one is loosened.
  • This dynamic behavior of the string 8 limits the positioning accuracy of the thread guide 7 for a given acceleration or deceleration and thus the traversing speed of the thread guide 7 for a given positioning accuracy of the thread guide 7. Since the requirements for the positioning accuracy of the thread guide are already very high with cross-wound bobbins and are still rising for windings according to any winding laws, the dynamic behavior of the string 8 mentioned would markedly limit the traversing speed and thus the winding speed.
  • the drive wheel 12 acts on the string 8 like a pretensioning element which presses laterally against the string and compensates for fluctuations in its tensions. Since each strand of the string 8 is guided from the fader guide 7 to the driving wheel 12, this resilient pretensioning member acts simultaneously on both strands of the string 8 and thereby prevents both the loosening of one strand and the other strand from being overstretched in the acceleration and deceleration phases String.
  • the sensor 13 has the great advantage that the scanning of the disk provided with the markings enables complete monitoring of the entire traversing movement, which would only be possible with an unacceptably high outlay in the case of the arrangement of the sensor along the path of the thread guide 7 which was previously customary. For this reason, one has not previously monitored the entire movement of the thread guide 7, but only its passage through a specific position, and has checked whether the motor 11 has possibly lost a step. Since with this method the current position of the thread guide was only known approximately, a certain safety margin always had to be taken into account in the performance of the motor 11, so that the motor 11 could not be operated at its performance limit.
  • the sensor 13 always relates its monitoring to an initial position of the thread guide 7, preferably to the zero point of its traversing movement.
  • the sensor 13 is set in such a way that the thread guide 7 first reaches the one reversal point and is then brought to the other reversal point, the sensor 13 counting the number of markings corresponding to this stroke and calculating the zero point therefrom.
  • the sensor 13 thus knows the number of scanning pulses between the zero point and the reversal points, so that the position of the thread guide 7 corresponding to a specific scanning pulse can be determined at any time on the basis of these scanning pulses.
  • the latter enables extremely precise control of the motor 11, the power of which can thus be fully utilized.
  • the tab 20 has on its free transverse edge, that is the left edge in the figure, a nose-like projection 23, to which an indentation 24 arranged on the adjacent inner edge of the edge region 19 of the base plate 16 is assigned.
  • the projection 23 and the indentation 24 serve as aids for adjusting the pretensioning of the string 8.
  • the projection 23 does not lie symmetrical to the indentation 24, but is slightly shifted downwards. The bias of the string 8 is then adjusted so that the projection 23 is symmetrical about the indentation 24.
  • Projection 23 and indentation 24 thus have the function of a marking indicating the position of the tab 20 in the pretensioned state of the string 8. Another marking could of course also be used for this. However, it has been shown that the marking formed by the projection 23 and the indentation 24 is very suitable, particularly under the conditions in a textile operation, as an adjustment aid for the pretensioning of the string 8.
