Definitions

  • the invention relates to a delivery device for running threads according to the preamble of the main claim.
  • the braking device often consists of a plastic ring with individual fingers which rest under elastic tension on the drum (DE-AS 19 00 619).
  • the thread tension is brought to a uniform value resulting from the contact pressure of the fingers and each finger is lifted off the surface of the thread storage drum when the thread is pulled under the finger, in order to then return to the contact position with the drum .
  • Similar things have already been done in such a way that the fingers come out like a comb from successive rings (DE-OS 25 55 802) and, above all, can also be adjusted with regard to the contact pressure to the thread storage drum (EP-OS 340 897).
  • the object of the present invention is to design a generic delivery device in such a way that the accuracy of the length of the drawn-off thread can be determined in a simple but optimal manner, in particular in order to obtain a thread length that is as precise as possible to be cut in the shed, in particular a jet loom.
  • a thread delivery device is created, which can be optimally assigned to a jet loom in particular, because it makes it possible to determine the length of the thread drawn off to such a degree of accuracy that corresponds to the circumferential distance between two adjacent switching fingers. Because of the large number of fingers, this circumferential distance can be extremely small, so the length of the cut thread can be determined with extraordinary precision.
  • the movement of each finger of the braking device is used to generate a switching pulse. This is fed to a measuring device. Adding the switching impulses results in a value that is directly proportional to the length of the thread being drawn, based on the circumferential direction distance between two switching fingers. It has been found to be important that if the braking force can be readjusted, a direct dependency can be taken into account even between the thread length drawn off and the thread take-up tension.
  • the thread storage drum 1 which is circular in cross section, has the frustoconical run-up surface 1 "behind the cylindrical outer surface 1 '.
  • the thread guide eyelet 2 moves in front of this.
  • the thread F runs in the region of the frustoconical surface 1" by relative rotation of the thread guide eyelet 2 to the thread storage drum 1. It squeezes into the angular groove 3 and thereby pushes the previously wound thread layers close together in the direction of the head end 4 of the thread storage drum 1.
  • the individual fingers 5 extending from the thread storage drum 1 extend above the head end 4. These sit electrically insulated on an insulating attachment 6 of the thread storage drum 1. They are designed to be elastic. They lay under spring tension, directed in the direction of arrow x against ring 7. This ring 7 is crowned on its underside 7 '.
  • the thread F is pulled overhead from the thread storage drum through the interior of the ring 7, preferably through a fixed eyelet 8. During this withdrawal, the thread slips between ring 7 and tongue 5 and lifts tongue 5 from the contact with ring 7. This lifting is registered as a contact impulse in that a line L + leads away from many or all tongues 5 and closes a circuit within a measuring device (not shown) to the ring 7 on the opposite pole L -.
  • the outward suspension of the fingers 5 is limited by the insulating shoulder 9 of an annular collar 10. This is located at the free ends of the wall 11 of a pot 12, which is assigned to the thread storage drum 1.
  • the fingers 5 are slightly tapered in their basic position towards the free end. Instead of the straight extension according to FIG. 2, they can also run slightly obliquely, preferably correspondingly the migration of the thread take-off point under the ring 7.
  • the ring 7 sits on a carrier 13 and is longitudinally displaceable thereon. Due to the longitudinal displacement setting, the effective free lever arm H of the fingers 5 can be varied and thus also the contact force in the direction of the arrow x and thus also the braking of the thread when the trigger is pulled.
  • the thread F is first wound in a winding movement, that is to say by a tangential feed onto the thread storage drum and stored there until a predetermined number of thread windings is present.
  • the transmitter of a light barrier 14 scans the lateral surface 1 ', for example. If the area of the preferably reflecting outer surface 1 'opposite it is covered by thread layers, the further thread supply is blocked or reduced by reducing the winding speed. If a pull-off now takes place, this area becomes free again and a corresponding switching device controls or increases the thread feed again.
  • the optimum thread take-off tension can be set by moving the ring 7. Not even this adjustment handling would prevent the contact function of the fingers 5.
  • the thread storage drum 1 does not need to be a stationary drum, as in the exemplary embodiment, but then the drum 1 could also rotate for the tangential feed of the thread, in which case the thread guide eyelet 2, as is also known, would stand still.
  • the delivery device according to the invention is assigned to the shed of a weaving machine, in particular in the jet mode with a blown air nozzle (D), in such a way that the thread drawn off is inserted into the shed W.
  • This shed length determines the length of the thread which has to be drawn off under a predetermined tension, after which this length is cut off by a cutting device S symbolized as scissors in the drawing, controlled by the measuring device of the delivery device.

Claims (4)

1. Dispositif délivreur de fils en déplacement, en particulier pour machine à tisser, comportant un tambour (1) de réserve de fil à une extrémité duquel arrive tangentiellement le fil (F) et duquel le fil peut être extrait à l'autre extrémité sous un dispositif de freinage (5/7), lequel dispositif de freinage possède des doigts individuels (5) formant ressorts, susceptibles d'être déplacés par le fil (F) en cours d'extraction, caractérisé en ce que les doigts (5) sont des languettes de contact d'un dispositif de mesure électrique de la longueur du fil (F) extrait.
2. Dispositif délivreur, en particulier selon la revendication 1, caractérisé par le fait que les doigts (5), isolés électriquement les uns des autres, sont portés par le tambour (1) de réserve de fil, et forment un pont de contact avec un anneau électriquement conducteur (7) qui les entoure, lequel est également connecté électriquement au dispositif de mesure, de sorte que le soulèvement des doigts provoqué par l'extraction du fil (F) donne lieu à une impulsion électrique vers le dispositif de mesure qui additionne ces impulsions de contact.
3. Dispositif délivreur, en particulier selon une ou plusieurs des revendications précédentes, caractérisé par le fait que les doigts (5) partent d'une garniture isolante (6) du tambour (1) de réserve de fil et présentent à l'extrémité libre un épaulement isolant (9).
4. Dispositif délivreur, en particulier selon une ou plusieurs des revendications précédentes, caractérisé par le fait qu'en vue du réglage de la force de freinage entre les doigts (5) et l'anneau (7), l'anneau (7) est susceptible d'être déplacé en translation en le sens longitudinal des doigts..
