Definitions

  • the invention relates to a spool having a plurality of wound layers of ribbon or thread-like winding material and wherein at least one mark is provided for displaying properties of the Spulguts.
  • the invention relates to a. Method for producing a marking on a coil having a multiplicity of layers of ribbon-like or thread-like package material.
  • the invention also relates to a device for detecting a marking on a coil.
  • spool a supply spool
  • processing on a loom is mentioned, in which the generally constant processing speed of the fabric defines the speed of unwinding from the spool.
  • An object of the invention is to provide a robust, wear-free and cost-effective solution with which the achievement of a certain winding position, such as the approaching end of the winding material during unwinding safely and reliably detected without certain properties of the Spulgutes such as color, conductivity etc. or there is a risk of contamination of sensors.
  • the solution should allow the recognition of certain properties of the Spulgutes, thus not only the filling state of the coil.
  • This task also includes a device by means of which the marking can be recognized without much effort.
  • US 3,062,481 discloses a coil which includes a signal in the form of a plurality of initially-wound small-width layers on the core; the overlying layers are wrapped across the full width. The material of the signal layers has correspondingly reduced contact angle. Other methods for producing markings on bobbins with windings of small winding width are shown in EP 0876985 A1 and EP 1 225 259.
  • the mark consists in that the winding material is wound in at least one position with the same laying angle as outside the mark and over a width which is significantly greater than the rated winding width of the coil differs.
  • the winding material is wound in at least one layer over a width which is significantly lower than the nominal winding width of the bobbin.
  • the Spulgut is wound in at least one layer so that the significant undershooting of the nominal winding width is present on one side.
  • the mark may also be a composite mark consisting of several individual markings.
  • the mark is inside the wound Spulguts.
  • the bobbin in this case has under the mark located Spulgut, which is wound over the Nennwickelbreite.
  • the object is also achieved with a device for detecting a mark on a spool, wherein the mark consists in that the Spulgut is wound in at least one layer over a width which differs significantly from the Nennwickelbreite, at least one of the transverse movement of the Spulguts at its Abwickeln detecting thread sensor is provided and the output signal of the yarn sensor is fed to an evaluation unit which is adapted to provide a marking signal, if the Spulgut covers a significantly different from the nominal winding width width of the coil during its unwinding.
  • the thread sensor is a sensor which optically detects the movement of the material to be spooled.
  • FIG. 1 is a schematic representation of a coil, from which is unwound Spulgut, in a view normal to the coil axis,
  • FIG. 2 shows the coil according to FIG. 1 a side view together with a device for detecting a marking
  • FIG. 3 is a view as in FIG. 1, a marking occurring during unwinding
  • FIG. 6 shows in a diagram the occurrence of a marking signal at the output of the evaluation unit.
  • the supply spool 1 shown in Fig. 1 with a bobbin tube 2 and wound thereon Spulgut 3 sits here on a mandrel 4.
  • the Spulgut can be band-shaped, thread-like or even a wire and it is guided by the coil in the direction indicated by an arrow and direction by a thread / tape guide, z. B. an eyelet 5, unwound.
  • a sensor 6 which is indicated in FIGS. 1 and 2.
  • This sensor 6 may, for example, be an optical sensor whose output signal is fed to an evaluation unit 7.
  • a marking of the coil which consists in that in at least one layer, the winding material is wound over a width Bi, which deviates significantly from the nominal winding width BN.
  • a position of the Spulgutes shown is, in which this is not wound on one side to the edge and thus only over a width Bi.
  • the laying angle of the Spulguts the mark M is equal to that outside the mark. If one compares Fig. 1 with Fig. 3 it can be seen that due to such a mark the Spulgut no longer passes the sensor 6 in its Hin and Hergang in the course of Abwickeins, so that it emits a corresponding signal or just no signal.
  • the pulse drops out for at least a short period of time because of the mark M.
  • Fig. 5 the example course of the yarn passage frequency F, starting from a full bobbin to the point of the mark M, is shown.
  • the thread passage frequency increases during the Abwickeins, assuming the case of a constant take-off speed of Spulguts 3, since with a smaller bobbin diameter, the spool rotates accordingly faster.
  • the yarn passing frequency F falls to zero and this mark M can indicate, as in the present case, that the end of the winding material is soon reached.
  • the Spulgut be wrapped again over the full width BN, d. h., the marking is located inside the wound material to be spooled.
  • the marking is generally produced by the coil that the winding material is not wound on one or both sides to the edge and thus only over a width Bi, which differs from the nominal width BN SO strong that the deviation significantly, 3, in the simplest case, the winding material can not be wound to the edge on only one side, as an alternative, it is also possible, if sufficient space is available at least one end of the spool is present to wrap the Spulgut also beyond the nominal width BN.
  • the most important and often unique marking will be a mark M at the end of the winder which results in the generation of a corresponding signal SM, starting from, for example, shutting down a machine to replace the now empty or nearly empty bobbin he follows.
  • a composite mark may be provided which consists of several individual markings, for. B. in the sense of a binary word exists, and defines or displays, for example, the Spulgut whatsoever or a batch number of the supply reel. It is also conceivable to set a mark, for example in the middle of the Spulgutes, which indicates a parent computing arrangement that already half of the Spulgutes is consumed.

Abstract

L'invention concerne une bobine (1) comportant une pluralité de couches enroulées d'un produit de bobinage (3) en forme de bande ou de fil, cette bobine étant pourvue d'au moins un marquage (M) pour l'affichage de propriétés du produit de bobinage, ce marquage consistant en ce que le produit de bobinage (3) est enroulé dans le même angle d'enroulement qu'à l'extérieur du marquage en au moins une couche dont la largeur se différencie de manière significative de la largeur de bobinage nominale (B<SUB>N</SUB>) de la bobine (1). Pour créer un tel marquage (M) le produit de bobinage est enroulé dans le même angle d'enroulement qu'à l'extérieur du marquage en au moins une couche dont la largeur diffère sensiblement de la largeur de bobinage nominale (B<SUB>N</SUB>) de la bobine. L'identification d'un tel marquage (M) est réalisée au moyen d'un dispositif comportant au moins un capteur de fil (6) qui saisit le mouvement transversal du produit de bobinage lors de son déroulement, le signal de départ du capteur de fil étant envoyé à une unité d'analyse (7) qui génère un signal de marquage (S<SUB>M</SUB>) lorsque le produit de bobinage, lors de son déroulement, dépasse une largeur de bobine différant sensiblement de la largeur de bobinage nominale.
