Definitions

  • the invention relates to a yarn feeding device for knitting or knitting machines.
  • the task may be to monitor the presence of the thread or to check or measure its tension.
  • the movably mounted lever therefore feels whether the thread is taut or whether it sags limply.
  • the lever is movably mounted to be moved transversely to the thread.
  • the positive thread delivery is achieved by running over the edge of a thread supply drum thread over a fixed hook that determines the expiration point of the thread.
  • a yarn guide loop is arranged in the immediate vicinity of a yarn feeler is arranged. This is formed by a pivotally mounted lever which carries an eyelet end, through which the thread runs. The lever is movable within a transverse to the thread, approximately horizontally oriented plane whose surface normal is oriented parallel to the axis of rotation of the yarn supply drum.
  • a set up for elastic threads thread supply device which includes a yarn tension sensor.
  • This comprises a horizontally arranged thread tension sensing lever which is pivotally mounted about a pivot axis parallel to the thread. As the thread tension changes, the thread tension sensing lever pivots up or down.
  • the yarn feeding device has at least one yarn feed wheel, which is rotatably mounted.
  • the thread feed wheel is associated with a thread guide device, which provides the thread take-off.
  • the thread guide device is set up for oblique withdrawal.
  • the yarn feeding device is a positive delivery device.
  • the thread is delivered by rotation of the yarn feed wheel to a yarn consumption point, such as a knitting point.
  • the yarn feeding device has a yarn feeler extending upwardly away from the yarn.
  • the yarn feeler is movably supported to at least distinguish whether the yarn is taut or limp.
  • it is movably mounted within a transverse to the thread-oriented plane, said plane preferably does not intersect the axis of rotation of the yarn feed wheel.
  • the pivot axis of the yarn feeler is thus preferably oriented approximately parallel to the yarn when it is pivotally mounted. This swings when the thread is flabby, sideways. Otherwise, ie when the thread is taut, it preferably hangs down substantially vertically from its storage.
  • a biasing device is used for bias in lateral Ausschwenkiques preferably a biasing device is used. This can by a suitable force generating means, such as a force acting on a lever arm weight, a spring means, magnetic Attraction or repulsion forces or the like may be formed.
  • the yarn feeler can serve in the form described both as a yarn inlet sensor and as a thread outlet sensor. In both cases, but especially in the latter case, it is expedient to arrange the yarn feeler immediately adjacent to a yarn guiding device.
  • the yarn feeler and the yarn guide device can form an assembly. It is advantageous if this is adjustably mounted with respect to the yarn feed wheel. For an adjustment of the thread flow or the drainage height of the thread is possible. With a sloped draft, the drainage angle can be changed to take into account the peculiarities of the thread used.
  • the height adjustment is also appropriate for adaptation to other suture drums with greater height. The height adjustment can be used to guide the thread of the yarn feed wheel relatively steep down. By stripping filaments (thread fragments, dust and the like.) The formation of filament rings is counteracted.
  • the direction of displacement or adjustment of the assembly is preferably parallel to the axis of rotation of the yarn feed wheel. In an adjustment of the position of this assembly, the position of the thread guide device and the thread feeler remain with respect to each other.
  • the yarn feeler can be designed as a thread monitor. In this case, it only differentiates between whether a tight thread is present or whether the thread sags or is missing. In this case, a means for distinguishing two positions of the yarn feeler, namely a first position which it assumes when the thread is taut and a second position which it assumes when the thread is limp, is sufficient.
  • the position detecting means may be a switch.
  • the yarn feeler may be formed as a thread tension sensor.
  • it can be connected to a sensor device which detects the magnitude of its deflection.
  • the path to be traveled by the yarn feeler can be reduced to a minimum.
  • a force measuring device only detects the force exerted by the yarn on the yarn feeler to determine the yarn tension therefrom.
  • the direction of action of the force exerted by the thread on the thread feeler is preferably oriented horizontally and transversely to the thread, the thread feeler being arranged vertically. Due to the vertical arrangement of the yarn feeler forces, which are caused for example by the weight of the yarn feeler and can be changed by Flusablagerung, ineffective in terms of yarn tension detection in this case.
  • the thread monitor can also be used as a thread store, which can absorb excess thread in the short term. As a result, small excess quantities are temporarily stored and released again when needed without the knitting machine switching off.
  • FIG. 1 a yarn feeding device 1 is illustrated, which serves to supply thread 2 to a knitting machine, knitting machine or other textile machine.
  • the yarn feeder 1 has for this purpose a yarn feed wheel 3, which is rotatably mounted on a support 4 and is looped around several times by the yarn 2.
  • the carrier 4 is provided at one end 5 with a mouth-like clamp 6, with which it is to be connected to a suitable holder, such as the machine ring of a knitting machine, as for example, the EP 0 333 482 A1 can be seen.

  • the yarn brake is formed for example by two by magnetic force adhering to each other rotatably mounted rings 8, between which the thread 2 passes.
  • the yarn feed wheel 3 is e.g. attached to a shaft 9, which is rotatably mounted on the carrier 4 and disposed in use substantially vertically. Its axis of rotation 10 is thus oriented approximately vertically. While the yarn feed wheel 3 is disposed below the carrier 4 at the lower end of the shaft 9, at the upper end thereof a drive means, for example in the form of a pulley 11 is arranged. There may be provided not further illustrated pulleys, which also serve to drive the shaft 9.
  • the yarn guide device 12 is arranged below the carrier 4 in a position which forces the thread 2 to a skew. In this, the thread 2 runs in strips over the lower edge 14 of the yarn feed wheel 3.
  • the yarn guide device may consist of one or more, in the present case, two eyelets 15, 16, which are formed for example as Keramikmaschine and arranged in a corresponding holder 17.
  • the eyelets 15, 16 may be as shown, closed rings or even with discontinuous annular elements, in which the thread is either threaded or inserted through the point of interruption. In the present case, the eyelets 15, 16 are arranged approximately at the same height and at a short distance from each other in order to keep between them a short piece of the running thread 2 calm.

  • the spring means 24 is in FIG. 2 indicated only schematically. It can also be formed by the elasticity of an end-fixed yarn feeler, by magnet arrangements or the like. Its function consists in the bias of the lever 19 in a predetermined direction, which in FIG. 3 indicated by an arrow 25.

  • the yarn feeler 18 is biased by the spring means 24 so that the thread eye 23 has a tendency to laterally from the in FIG. 2 swing out illustrated position. However, the relatively tight thread 2 prevents this, so that the yarn feeler 19 is forced into a substantially vertical orientation.

Abstract

L'invention concerne un dispositif délivreur de fil (1) à palpeur de fil amélioré. Le palpeur de fil (18) et un guide-fil associé (12) y constituent de préférence un ensemble qui peut être déplacé parallèlement à l'axe de rotation de la roue délivreuse de fil (3). Le palpeur de fil (18) comprend un levier (19) ou autre élément qui est de préférence disposé en position verticale. Cet élément s'étend ainsi en éloignement du fil dans une première direction transversale. Dans une première forme de réalisation, cet élément est mobile dans une seconde direction transversale (direction de pivotement), tandis que dans une seconde forme de réalisation, il est monté à translation longitudinale. Comme le mouvement du palpeur de fil est orienté exclusivement transversalement et de préférence perpendiculairement au fil, les impulsions de déplacement agissant sur le palpeur sont minimisées. La disposition verticale du palpeur de fil permet en outre d'utiliser le palpeur pour une très large plage d'épaisseurs de fil, allant du fil polyester le plus mince aux épais fils fantaisie.
