Definitions

  • the invention relates to a winder for simultaneous winding of at least two threads on an equal number of winding points arranged in series next to one another with the aid of a belt-traversing device, which has the following features:
  • At least two pairs of deflectors are arranged in accordance with the number of winding stations, which mark the reversal points of the individual traversing areas and are suitable for transferring a thread from one driver to an oncoming driver. State of the art.
  • Dishwashers For winding at extremely high thread speeds - e.g. ⁇ ,000 m / min. - Dishwashers are known in which the thread is guided back and forth by drivers which are fastened on two belt or belt spaces which are moved in opposite directions and are arranged next to one another.
  • the alternating movement of the thread is not brought about by a single thread guide moved back and forth as in conventional traversing devices, but by the fact that the oppositely moving drivers alternately grasp and guide the thread. Since the drivers at the reversal points of the thread are neither accelerated nor decelerated, the influence of the inertial mass of the thread guiding elements during thread reversal is completely eliminated.
  • the meeting point with the next driver of the other belt section is at a distance from the first meeting point that is half the distance between two adjacent drivers of a belt belt. This results from the fact that the belt spaces move in the opposite direction at the same speeds. Since the thread is transferred from a driver of one belt strand to a driver of the other belt strand at a meeting point, the traversing stroke is equal to the distance between two meeting points. The transfer is effected by suitable shaping of the drivers and facilitated by stationary deflectors which are arranged at the meeting points.
  • a traversing device is indicated schematically in DE-OS 35 05 188, in which the distance on which the belt strands run side by side is a multiple of the distance between two drivers. Therefore, there are several meeting points on this route at regular intervals. This is exploited to work with a single pair of
  • a length compensation should be carried out on the circumferential belt strands.
  • the belt spaces between two adjacent traversing areas are deflected out of the traversing plane with the aid of deflection rollers, the detour distance being an even multiple of the traversing length.
  • the arrangement of the deflection rollers is structurally more complex, the more winding stations are arranged on a winding mandrel. In practice, it should be difficult to accommodate more than two winding stations on one winding mandrel.
  • a conversion of a machine that is equipped for a certain number of winding stations to a different number of winding stations should - if at all - only be possible with substantial modifications.
  • This object is achieved in that the center distances of the traversing areas are half as large as the distances of the drivers of a belt strand and that the effective distances of the two deflectors of a traversing area are smaller than the center distances of the traversing areas.
  • the "effective distance" between the two deflectors is the distance between the points at which the thread is actually released by the arriving catch from the deflector.
  • the effective distance is therefore equal to the traversing stroke.
  • the effective distance is deliberately made smaller than the distance between two meeting points; the difference is used to maintain the indispensable distance between the end faces of two adjacent coils.
  • deflectors are displaceable in the longitudinal direction of the axis of a winding mandrel and are coupled by a gear with a contact element lying on the winding surface in the sense of a distance between the two deflectors of a traversing area which becomes smaller with increasing winding diameter. This makes it possible to reduce the effective spacing of the deflectors with increasing winding diameter and in this way to produce coils with conical or curved end faces.
  • Figure 1 shows schematically the winding machine, partly in section, from the side.
  • Figure 2 shows a view of the traversing device.
  • Figure 3 shows the arrangement of the windings in section.
  • Figure 4 shows the traversing device from above.
  • Figure 5 shows - pulled apart in the transverse direction - individual parts of the traversing device from above.
  • a sleeve 1 with a winding 2 on a winding mandrel 3 can be seen in FIG.
  • the dishwashing machine has a total of four winding positions lying side by side, i.e. on the mandrel 3 there are a total of four sleeves with four windings.
  • the winding mandrel 3 is connected to a machine frame (not shown) in such a way that its position relative to the machine frame does not change during the construction of the winding 2. He can e.g. sit on a revolver head.
  • a traversing device 6 is accommodated in the housing 4 in close proximity to the drive roller 5.
  • the filters corresponding to the number of Wickel ⁇ centered over the associated winding station, threads 8 are supplied at a high speed of the traversing device 6, passed through a short free span, then lie on an arc of slightly more than 90 ° to the surface of the driving roller 5 and from there reach the winding 2.
  • the driving roller 5, together with the traversing device 6, deviates upwards, as symbolized by the arrow 9.
  • the traversing device 6 is arranged in the housing 4 on a cross member 10.
  • a motor 13 with a toothed drive pulley 14 sits on a plate 11 welded to the crossbar 10, adjustable by means of an adjusting screw 12 in the longitudinal direction of the crossbar 10.
  • At the other end of the crossbar 10 there is also a toothed deflection pulley 15 on a slide 16 stored, which is slidably guided on guide rods 17 in the direction of the crossmember 10.
  • the upper run 21 of the toothed belt 20 is deflected by two further toothed pulleys 22, 23, which are mounted in the vicinity of the drive pulley or the deflection pulley 15, so that it runs parallel to the lower run 24 at a short distance.
  • upper run 21 runs in the direction of arrow 26
  • lower run 24 runs in the opposite direction according to arrow 27.
  • drivers 28 are fastened at regular intervals.
  • a bearing housing 29 is fastened to the crossmember 10 close to the toothed disk 22, in which a gearwheel 30 is mounted with a horizontally lying axis.
  • a guide block 31 is fastened on the other side of the traverse 10 in the vicinity of the toothed disk 22, which is adjacent to the motor 13.
  • An upper push rod 32 and a lower push rod 33 are slidably guided in bores in the guide block 31 and the bearing housing 29, parallel to one another and to the two runs 21, 24 of the toothed belt 20. Both push rods 32, 33 are provided in the area of the bearing housing 29 on the mutually facing sides with teeth which mesh with the gear 30 at 180 ° offset positions.
  • the guide rail 38 can be pivoted about a pivot 39 which is seated in a fork 39 welded to the machine frame. In the basic position represented by solid lines, the guide rail 38 is arranged vertically, i.e. perpendicular to the direction of the runs 21, 24 and accordingly also perpendicular to the winding axis.
  • connecting pieces 44, 45 are firmly clamped, which reach down to the height of the strands 21, 24.
  • a thin strip 46 is screwed to it, which lies flat in the narrow space between the runs 21, 24 and extends almost over the entire free length between the toothed disks 22, 23.
  • the connecting pieces 44, 45 are provided with bores in which the lower push rod 33 slides freely.
  • the bar 46 is in gleich ⁇ regular intervals with a total of four deflectors 47a - provided 47d (in particular figure ⁇ ), the forward over the area occupied by the drivers 28 the leading edge of the timing belt 20 a little further extend than the driver 28 itself, the deflector 47th the strip 46 are beveled in a wedge shape on the flank facing the motor 13 - to the left in the drawing.
  • a strip 50 connected, which is also just below the strip 46 between the strands 21, 24.
  • the strip 50 has four deflectors 51a-51d, which are arranged at the same intervals as the deflectors 47a-47d and, like these, are provided with a wedge bevel, but ' on the opposite side, on the right in the drawing.
  • the distance x between two deflectors 47a-47d is exactly half the distance y between two adjacent drivers 28a-28d; the same applies to the spacings of the deflectors 51a-51d.
  • a total of four threads 8a-8d run to the dishwasher shown in the drawing (FIG. 5).
  • the threads 8a and 8c are moved to the right by the drivers 28a and 28c of the upper run 21 in the drawing, the threads 8b and 8d by the drivers 28b and 28d of the lower run 24 to the left.
  • the threads 8a and 8c are already in contact with the wedge-shaped rising flanks of the deflectors 47a, 47c, as are the threads 8b and 8d with the flanks of the deflectors 51b, 51d, which are bevelled in the opposite direction.
  • the threads 8a and 8c are located immediately before the right reversal point of their traversing area, the threads 8b and 8d before the left reversal point. In the following instant, all the threads are released from contact with the associated driver by the deflectors and - due to the central arrangement of the thread guides 7 above the assigned winding stations - reverse their direction of movement. After they have initially moved freely, one driver takes each of them, namely the thread 8a from the driver 28b, the thread 8b from the driver 28a, the thread 8c from the driver 28d and the thread 8d from the driver 28c.
  • the total of four traversing areas are delimited by the deflector pairs 47a-51a, 47b-51b, 47c-51c and 47d-51d.
  • the exact limit of the traversing area lies in each case at the point at which the wedge bevel of the deflector penetrates the plane in which the outermost tips of the drivers 28 run.
  • the effective distance z i.e. the distance i defined by the limits of the traversing area, is smaller than the center distance x of two neighboring changie areas, which - in accordance with the distance between adjacent deflectors 47a - 47d or 51a - 51d - is exactly half as large as the distance y between two adjacent drivers 28a-28d.
  • the wraps have flat end faces.
  • the length of a roll - ie the distance between its two end faces - corresponds to the effective distance z.
  • the length of the sleeve is x.
  • the distance between the mutually facing end faces of two adjacent windings, ie the difference between x and z, can be small compared to the length of the windings.
  • the sleeve only needs to protrude a little from the end faces of the finished winding, so that the windings do not slide off the sleeve ends and there is also enough space for a knot winding.
  • the toothed belt 20 is exchanged for another toothed belt which has twice the number of drivers over the same length.
  • the strips 46, 50 are to be replaced by strips with correspondingly closer deflectors.
  • the gearbox for the automatic deflection of the deflectors remains unchanged; if necessary, the cone angle can be changed by simply adjusting the guide rail 38.
  • the preferred embodiment of the invention is that which has been shown in the drawing. It is characterized, among other things, by the fact that the two belt spaces belong to a single continuous endless belt. However, the invention is also applicable to dishwashers whose belt changer has two circumferential endless belts, with one strand of one belt lying next to an oppositely moving strand of the other belt, as is known from the documents cited in the prior art.
  • the main application of the Au dishwasher according to the invention is the production and processing of threads made of synthetic material.

Abstract

Une machine de bobinage pour enrouler simultanément au moins deux fils sur autant de points d'enroulement disposés en séquence l'un à côté de l'autre, est équipée d'un dispositif d'ensouplage croisé à courroie. L'ensouplage croisé est réalisé par des éléments d'entraînement (28a-28d) contrarotatifs qui sont situés à des intervalles réguliers (y) sur une courroie crantée (20) en rotation et saisissent, en alternance, les fils (8a-8d). Les points d'inversion des régions d'ensouplage croisé des points d'enroulement inviduels sont repérés par des déflecteurs (47a-47d; 51a-51d). La distance effective (2) entre deux déflecteurs correspondants (47a-51a; 47b-51b; 47c-51c; 47d-51d), qui détermine la course d'ensouplage croisé, est inférieure à l'entre axe (x) de deux régions d'ensouplage croisé. Cette distance est exactement égale à la moitié de la distance (y) entre deux éléments d'entraînement adjacents (28-28d).
