Definitions

  • the present invention relates to a needling machine installation comprising a needle board whose needles perform a back and forth movement inside a sheet or web of fibers, in particular non-woven, passing in front of them, with a view to consolidating it.
  • the present invention also relates to a method of operating an installation of this type.
  • a needling machine comprising a needle board and two plates between which passes a sheet of fibers to be needled and means for eliminating flying fibers by intermittent jets of air on the outer faces of the plates.
  • the present invention aims to overcome the drawbacks of the prior art by providing a needling machine installation which makes it possible to increase the production rate of consolidated sheet or veil, in particular by avoiding untimely interruptions of the line.
  • an installation is according to claim 12.
  • the means for monitoring, in particular for measuring, the vibrations and/or deformations of the stripper plate comprise an accelerometer sensor, in particular arranged on the stripper plate.
  • the means for monitoring, in particular for measuring, the vibrations and/or deformations of the stripper plate comprise means for monitoring, in particular for measuring, the stresses exerted on the fixing and/or support points of the stripper plate.
  • alert means capable of giving an alert when the quantity of accumulated fibre dust monitored, in particular the thickness of the layer of accumulated fibre dust monitored, in particular measured, exceeds a threshold value determined in advance.
  • the installation comprises a stripper plate which is pierced with a field of through holes and which is crossed by the needles before they penetrate the veil or the sheet of fibers and the alert means give the alert when the difference between the vibrations and/or deformations monitored over time and the vibrations and/or deformations when empty exceeds a threshold value determined in advance.
  • the implementation of the elimination means is carried out after stopping the operation of the installation.
  • a needling installation comprises a board 1, from a lower face of which protrude needles 2 arranged according to a field of needles which is conventionally produced according to a so-called random or quasi-random pattern, the definition of random or quasi-random being well known in the field.
  • MD Machine Direction
  • Support means in particular in the form of a support table 6, support the veil or the tablecloth during its movement, the support table 6 being able in particular to be pierced with holes in correspondence with the needles.
  • a stripper plate 8 for example in the form of a sheet metal, pierced with through holes in a pattern corresponding to that of the needles, is arranged between the needle board 1 and the web or the fiber sheet.
  • the through holes of the stripper correspond to the holes drilled in the support table 6.
  • the needles as is conventional in the field, have barbs.

Claims (12)

  1. Verfahren zum Betreiben einer Nadelmaschine mit einer Nadelplatte (1) mit einem Nadelfeld und Mitteln (3) zum Antreiben der Nadeln in einer Hin- und Herbewegung, insbesondere in vertikaler Richtung, sodass die Nadeln in einer Bewegungsrichtung in einen Vliesstoff oder eine Vliesstoffbahn, insbesondere ein Faservlies, in einer zur Bewegungsrichtung des Vliesstoffs oder der Vliesstoffbahn - insbesondere senkrecht - verlaufenden Richtung eindringen und anschließend in einer zweiten Bewegungsrichtung wieder aus dem Vliesstoff oder der Vliesstoffbahn austreten, wobei sich auf der Nadelplatte zwischen den Nadeln eine Menge an angesammeltem Faserstaub befindet, wobei
    - die auf der Nadelplatte zwischen den Nadeln vorhandene Menge an Faserstaub überwacht wird (9; 13; 15, 16), und
    - bei Überschreiten eines Schwellenwerts der überwachten Faserstaubmenge Mittel zur Entfernung des angesammelten Faserstaubs auf der Nadelplatte eingesetzt werden.
  2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass der Vliesstoff oder die Vliesstoffbahn während ihrer Bewegung vor den Nadeln von einem Tisch (6) getragen wird.
  3. Verfahren nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die Anlage eine Entstaubungsplatte (8) umfasst, die mit einem Feld durchgehender Löcher versehen ist und von den Nadeln durchquert wird, bevor diese in den Vliesstoff oder die Vliesstoffbahn eindringen.
  4. Verfahren nach Anspruch 3, dadurch gekennzeichnet, dass die Mittel zur Überwachung der Menge an Faserstaub, der sich auf der Platte zwischen den Nadeln ansammelt, Mittel (9; 13; 15) zur Überwachung der Vibrationen und/oder Verformungen der Entstaubungsplatte umfassen.
  5. Verfahren nach Anspruch 4, dadurch gekennzeichnet, dass die Mittel zur Überwachung der Vibrationen und/oder Verformungen der Entstaubungsplatte einen Beschleunigungssensor (9) umfassen.
  6. Verfahren nach Anspruch 4 oder 5, dadurch gekennzeichnet, dass die Mittel zur Überwachung der Vibrationen und/oder Verformungen der Entstaubungsplatte Mittel (13) zur Überwachung der Spannungen umfassen, die auf die Befestigungs- und/oder Stützpunkte (12) der Entstaubungsplatte ausgeübt werden.
  7. Verfahren nach einem der Ansprüche 1 bis 6, dadurch gekennzeichnet, dass Warnmittel vorgesehen sind, die geeignet sind, eine Warnung auszusenden, wenn die Menge des auf der Nadelplatte zwischen den Nadeln angesammelten Faserstaubs einen vorbestimmten Schwellenwert überschreitet.
  8. Verfahren nach Anspruch 7, dadurch gekennzeichnet, dass die Warnmittel eine Warnung ausgeben, wenn die Differenz zwischen den zeitlich überwachten Schwingungen und/oder Verformungen und den Leerlaufschwingungen und/oder - verformungen einen vorbestimmten Schwellenwert überschreitet.
  9. Verfahren nach einem der Ansprüche 7 oder 8, dadurch gekennzeichnet, dass Steuermittel (10), insbesondere elektronische Steuermittel, vorgesehen sind, die die Warnmittel und/oder die Mittel zur Beseitigung der Faserstaubansammlungen betätigen, wenn festgestellt wird, dass die Menge an angesammeltem Faserstaub einen vorbestimmten Schwellenwert überschreitet, insbesondere wenn eine Veränderung der Vibrationen und/oder Verformungen der Entstaubungsplatte festgestellt wird, insbesondere wenn sie einen Schwellenwert überschreiten.
  10. Verfahren nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass die Bewegung der Nadeln entlang einer geradlinigen Bahn erfolgt.
  11. Verfahren nach einem der Ansprüche 1 bis 9, dadurch gekennzeichnet, dass die Bewegung der Nadeln entlang einer elliptischen Bahn erfolgt.
  12. Anlage zur Durchführung des Verfahrens nach einem der vorhergehenden Ansprüche.
