Definitions

  • the invention relates to a device for dedusting the yarn feed mechanism of a knitting machine, especially a circular knitting machine, with a Blow air device, from which at least one on the Thread feeder directed air flow emerges.
  • the invention is therefore based on the object to avoid undefined fiber flight as far as possible and in particular to prevent fibers from forming on the threads supplied by the thread delivery unit lower so that they reach the needle front and / or be knitted in.
  • this object is achieved by that the air flow is such that its area of effect essentially outside the zone lies in which the from the yarn feeder to Stretch the knitting area of the machine-running threads.
  • the yarn feeder by means of the directed air flow blow the yarn feeder, however Make sure that the fiber-enriched Air flows and is discharged in such a way that it does not get into the zone in which the from the yarn feeder and to the knitting area of the knitting machine extending threads.
  • the air flow is such emerges from the blowing air device that he in is substantially outside the zone. Hence occurs the air flow from the blowing air device already aligned so that its scope and do not touch, cross, or the like.
  • the air flow is essentially vertical down, preferably in the outer area of the Knitting machine, runs.
  • the invention thus a completely different way by the air flow is blown from outside to outside, that is, it remains on the outside, around itself the circular knitting machine extending area and runs from top to bottom, preferably approximately vertically from top to bottom. This ensures that the directed airflow is not is blown onto the threads, as these come from the thread feed mechanism extend diagonally downwards and inwards, the blown air from the outside, however, from above runs down. So there is no fiber bombardment of threads.
  • the blowing air is preferably such trained that preferably directed, turbulent Rays are present that are both single fibers as well as fiber agglomerates, especially in places like Thread brake, thread monitor, thread deflection points, etc. solved and consequently blown off. With the Air flow thus get these pollutants from top down to the floor area of the outer zone the knitting machine.
  • the contaminants mostly fibers or fiber agglomerates, are deposited on the ground and then disposed of. Disposal is preferred via a suction device.
  • the suction device is preferably located in the floor area.
  • This air flow is not for the airflow already mentioned, but for one further exposure to air.
  • a relatively high flow rate preferably about 15 m / s, has the air flow a speed of about 1 m / s.
  • This Values are only reference values that are used in practice other sizes and relationships to each other can have.
  • the air flow is preferred in Direction towards the knitting area from an air delivery device blown out.
  • the Air flow essentially vertical from above blown down, this being inside the knitting machine is done so that the air flow directly from top to bottom towards the knitting area reached.
  • the drawing illustrates the invention with reference to of an embodiment, the -in schematic Representation - one with blowing air device and air delivery device provided circular knitting machine concerns.
  • the figure shows a circular knitting machine 1 Knitting machine 2 on the floor 3 a Installation room (machine room or similar) is set up.
  • the circular knitting machine 1 has a circumferential knitting area 4 to which a plurality of threads from a thread feed mechanism 5 6 run.
  • the yarn feeder 5 extends circular around the circular knitting machine 1 and is at a higher level than the knitting area 4, so that the variety of approximately radial extending threads 6 on an imaginary cone jacket lie.
  • the machine frame of the circular knitting machine 1 is located in an interior area 7 around it is an outer area 8 quasi ring-shaped extends. Inside the outside area 8 is the yarn feeder 5 or Feeders. Above the yarn feeder 5 in the outer area 8 a circular air device 9.
  • the air flow 11 can assemble a large number of individual air flows, all on the corresponding section of the yarn feeder 5 are directed and consequently blow off the existing parts and thus an enrichment of fibers or fiber agglomerates and the like prevent.
  • the Air flow 11 flows from the yarn feed mechanism 5 enriched with fibers and the like - vertically from the bottom and - in the course of its further course of flow - in the outer zone 8 to the floor area 12, that is, one around the outside of the machine frame the circular knitting machine 1 area above the floor 3.
  • the floor 3 is preferred -a ring around the circular knitting machine 1
  • Suction device 13 installed with the Air flow 11 contaminated with fibers is disposed of. It is possible to form a cycle, that is, to clean the extracted air accordingly and if necessary, moisten and / or temper and then to the blown air device 9 again.
  • the air flow has a relatively high flow rate in the outdoor area 8.
  • an air flow 15 creates a relatively low Has speed and laminar flows.
  • the air flow 15 is perpendicular downwards directed, that is, it would theoretically be in the center of the machine frame of the circular knitting machine 1 meet. Because due to the air flow 15 but inside the circular knitting machine 1 Overpressure forms (overpressure zone 16) flows Air flow 15 laminar on all sides to the outside and reaches the outdoor area in this way 8 around the circular knitting machine 1.
  • the air flow 11 touches or crosses the zone 17 in this respect essentially not, whereby a fiber transport avoided in the area of the threads 6 and consequently an accumulation of fibers on the threads 6 is prevented.
  • the one revolving Compressed air jet (arrow 18) creates and helps that the needle front from accumulating Fuzz, fibers and the like remain free.
  • a corresponding blowing air device can also in Base area of the circular knitting machine 1 may be provided (Arrow 19) to also collect fiber agglomerates there and the like in the outer region 8 blow so that they there by means of the suction device 13 can be disposed of.
