Definitions

  • the invention relates to a winding machine according to the preamble of claim 1.
  • a winding machine is, for. B. known from DE-A-34 04 303, EP-A-120 216, DE-C-34 17 457, DE-A-37 03 731 A1.
  • the guide ruler has the following function:
  • the driver arms have a constant angular velocity, but in the traversing direction, in which the thread is to be moved back and forth parallel to the bobbin axis, the guiding speed differs between the stroke ends.
  • the guiding speed depends on the constantly changing angular position of the wings and is therefore meaningful.
  • the main guideline deflects the thread out of the traversing plane in such a way that these speed differences are compensated for in the desired manner.
  • the traversing plane is the tangential plane that is created by the head thread guide and the next rotating cylinder. on which the thread runs, is stretched.
  • the head thread guide lies in the middle above the traverse stroke. It is at such a distance from the rotary cylinder that the thread accommodates the thread tension fluctuations caused by the traversing movement can endure. These thread tension fluctuations result from the fact that the thread length between the head thread guide and the rotating body changes continuously as a result of the traversing movement, that is to say increases and decreases.
  • the rotating body is generally a contact roller, on which the thread runs and which the thread partially wraps around, in order to then run towards the bobbin.
  • the object of the invention is. to avoid these large differences in the wrap angle, which also lead to different thread tensions, and thereby enable large traversing strokes.
  • the maximum wrap angles which naturally occur in the area of the greatest deviation of the guide rulers from the traversing plane, can be reduced very greatly.
  • An arrangement is preferred in which the maximum wrap angles are approximately the same size, so that the thread tension within certain Limits remain.
  • the advantage of the invention is that an inadmissible reduction in the thread tension in the end regions of the traverse stroke can be avoided.
  • the thread tension In the known winding machine, the thread tension must be chosen so high that it does not fall below a minimum value even in the stroke end areas. On the other hand, this means that the thread tension is relatively high in the central region of the traversing stroke.
  • the development according to claim 2 also brings about an equalization of the thread tension.
  • the bobbin When winding a multifilament thread, the bobbin must be manufactured in such a way that the thread can run off the bobbin even at high speed. It becomes possible in particular when the thread is deposited on the bobbin in a closed form, ie: as if it were a uniform, essentially round body. The opposite of this is that the individual filaments that make up the thread are placed side by side on the spool. In this case, when the thread runs off, there is a risk that the individual filament elements belonging together will not come loose from the winding surface simultaneously and uniformly. The thread then runs unevenly and thread breakage or filament breakage can occur.
  • Claim 3 has the particular advantage that in this embodiment of the invention the thread is deposited on the bobbin as a closed body - and not as a wide band consisting of individual filaments. In particular, it is avoided in this embodiment that a connection of the individual filaments that was previously through Blow out a sharp air flow on the thread has been made (tangling), is picked up and dissolved again.
  • the embodiment according to claim 4 allows a particularly exact thread transfer from one wing to the other in the reversal areas and avoids the mechanical engineering problem of the tight response of the guidelines.
  • the main guide In principle, it is possible to arrange the main guide on one or the other side of the thread plane. However, it is preferred that the main guide lies between the thread running plane and the rotor axis plane (claim 5). This is particularly advantageous for the operation and application of the thread.
  • the respective guide rule consists of a frame attached to the machine frame and circumscribing a window. The part of the frame that projects into the traversing plane forms the guideline. For the rest, the window is cut out so far that especially the end regions of the traversing stroke, in which the thread is transferred from one wing to the other, are visible.
  • a thread runs over a head thread guide 13 to a traversing device and from there to a contact roller 12.
  • the thread loops around the contact roller 12 partially, e.g. B. at 60 ° and then runs on the coil 16.
  • the contact roller is in circumferential contact with the coil 16.
  • the coil 16 is formed on a cardboard sleeve or plastic sleeve 15.
  • the plastic sleeve 15 is clamped on a spindle 14.
  • the spindle 14 will driven at a speed. which decreases in the course of the winding travel.
  • the spindle drive is controlled as a function of the speed of the contact roller 12, which is measured for this purpose.
  • the control of the spindle or the spindle drive is done in this way. that the speed of the contact roller 12 remains constant.
  • the traversing device consists of the rotors 1 and 2, on which several driver arms - also called wings in the context of this application - are attached.
  • the rotor 1 has z. B. two drive arms 5 and 6, which are each offset by 180 ° to each other.
  • the rotor 2 has the driver arms 3 and 4, which are also offset from one another by 180 °.
  • the rotors are arranged so that the driver arms 6 on the one hand and 3, 4 on the other hand rotate in two closely adjacent, mutually parallel planes of rotation. However, as can be seen from FIG. 5, the rotor axes are arranged eccentrically parallel to the coil.
  • the rotors are driven with the opposite direction of rotation and a phase shift of 90 °. If each of the rotors z. B. has three driver arms, these are offset by 120 ° to each other.
  • the thread is guided along a guide ruler 9 (main guide ruler).
  • a guide ruler 9 main guide ruler
  • Such a traversing device is described, for example, in EP-A-114 642 (Bag. 1321).
  • FIGS. 1 and 5 The following is shown in FIGS. 1 and 5:
  • Each of the rotors 1 and 2 of FIG. 5 has two to each other by 180 ° offset driver arms 3 and 4 or 5 and 6.
  • the driving arm 5 currently has the thread guide and guides the thread to the left. At the traversing stroke end (line 7), it delivers the thread to the oncoming driver arm 7 of the rotor 2 rotating in opposite directions.
  • the main guide ruler 9 projects into the traversing plane with a certain shape, which is indicated here as line 10; ie: The thread comes from the direction of the viewer and the traversing plane is perpendicular to the paper plane.
  • the auxiliary guide rulers 11 are arranged in two planes that are closely adjacent to both the rotational planes of the driver arms and to one another.
  • the main guideline protrudes from the same side into the traversing plane as the drive arms.
  • the auxiliary guidelines 11 protrude from the opposite side into the traversing plane 10.
  • the main guide ruler 9 and the auxiliary guide ruler 11 overlap in the stroke end regions.
  • the auxiliary guidelines take over approximately or preferably - viewed from the center of the traversing stroke - somewhat before the intersection of the traversing plane 10 with the Main guideline 9. This ensures that the wrap angles on the main and auxiliary rulers are approximately the same size.
  • the main guide 9 and the auxiliary guides 11 do not necessarily have to be arranged such that an overlap (view in the thread direction) takes place. Rather, the relative arrangement of the guide lines depends on the overall geometric arrangement of the thread path, the traversing device, the contact roller and the bobbin.
  • phase IV the main ruler has completely withdrawn from the traversing level.
  • the thread is now guided exclusively by the auxiliary guide.
  • the traversing stroke end is shown in phase V.
  • the thread is transferred from one wing 4 of one rotor to the other wing 6 of the other rotor.
  • the auxiliary guide also has the sole guidance of the thread in the traversing direction.
  • FIGS. 6 and 7 Another special feature of the exemplary embodiment according to FIGS. 6 and 7 is that the main guide 9 and the auxiliary guides 11 are arranged in closely spaced parallel planes in front of the wing planes. This arrangement ensures that the thread does not break down into its individual filaments when it is lifted off on the contact roller 12 or the bobbin. Rather, the thread is deposited on the spool as a closed bundle of filaments and consequently also pulled off the spool as a closed bundle of filaments during unwinding. In the described wing maneuvering, it is necessary to adjust the wings on the rotors exactly so that the thread is transferred from one wing to the other wing at a certain point. For this you have to be able to watch the wings. Windows 17 of the main guideline and 18 of the auxiliary guideline serve this purpose. The guidelines are designed as a frame that leaves one window open.

Abstract

Une machine d'embobinage permettant d'enrouler un fil amené en continu de manière à former une bobine en croix comprend un dispositif d'ensouplage qui guide le fil en va-et-vient le long d'un trajet prédéterminé transversal au sens d'écoulement du fil. La machine d'embobinage a les caractéristiques suivantes: le guide-fils est fixé au-dessus de la course d'ensouplage, à peu près au centre de celle-ci, et définit un plan tangentiel à un cylindre rotatif en aval du dispositif d'ensouplage. Des bras d'entraînement (5, 6, 7, 8) sont assujettis à deux rotors (1, 2) qui tournent en sens inverse, dont les axes se situent dans le même plan (12) et dont les ailes se déplacent dans deux plans parallèles étroitement adjacents qui coupent le plan (12) des axes des rotors à la perpendiculaire. Une première règle-guide (9) située d'un côté du plan (10) de transport du fil sur un plan parallèle et étroitement adjacent à un des plans des ailes fait saillie dans le plan d'ensouplage et dévie ainsi le guide-fil de tête (13) de sorte que le fil soit amené en va-et-vient dans le sens d'ensouplage à une vitesse d'ensouplage sensiblement constante ou prédéterminée selon une loi déterminée de mouvement. Des règles-guides auxiliaires (11) au niveau des extrémités de la course d'ensouplage se situent dans un plan parallèle au plan des ailes mais du côté du plan d'ensouplage (10) opposé à la règle-guide principale (9). Les plans (12) des axes des rotors et la règle-guide principale (9) sont situés par rapport au plan d'ensouplage (10) de telle sorte que la règle-guide principale ne pénètre pas dans le plan d'ensouplage dans la zone des extrémités de la course d'ensouplage, alors que les règles-guides auxiliaires (11) pénètrent dans le plan d'ensouplage dans la zone des extrémités de la course d'ensouplage et assurent le guidage du fil et la détermination de la vitesse d'ensouplage.
