Definitions

  • the invention relates to a feeding device for cards, cards and the like. with a vertical first shaft, at the lower opening of which a feed roller is arranged in the center, and a beater roller arranged below the feed roller, from which a second substantially vertical lower shaft extends tangentially.
  • the fiber material is fed under the action of gravity and with air pressure support from a first shaft called a reserve shaft to a trough feeder in which a feed roller is arranged (DE-PS 28 04 413).
  • the feed roller pushes the flaky fiber material into one half of the trough, from where it exits through an opening in the lower region of the trough.
  • Below the feed roller is a rotating impact roller which has impact bars on its peripheral surface. This impact roller, which rotates in the same direction of rotation as the feed roller, not only cuts off the circumference of the feed roller fiber material, but its blow bars move from the area of the trough opening to the tip of the opening edge.
  • the fiber material which is located in the area of the opening edge, is: subjected to a strong deflection around this opening edge and thus to a strong shear and tensile stress. Due to this high impact load at the edge of the opening, there is a risk that the fiber material will break and tear. This danger arises in particular when the fiber material forms coherent tufts which are smashed to a certain extent by the blow bars at the deflection point.
  • FR-A-2599055 describes a feeding device for cards and cards, in which the feed roller is arranged in the center at the lower end of the upper shaft.
  • the lower shaft runs offset to the upper shaft.
  • the feed roller and the beater roller rotate in the same direction.
  • a nip between the two rollers is not provided, rather there is only one nip between the feed roller and a trough formed by the wall of the upper shaft.
  • the disintegrated fiber flakes can roll on the shaft wall in the area of the beater roller, which can lead to undesired agglomerations.
  • the invention has for its object to provide a feeding device of the type mentioned, in which the stress on the fiber material at the opening is reduced and with which rolling of the fiber material along shaft walls is prevented.
  • the feed roller is arranged essentially centrally in the shaft cross section at the end of the first shaft.
  • the second shaft runs essentially in an extension of the first shaft, as a result of which the flake material runs from the first shaft into the second shaft in a substantially straight path, with the greatest possible protection of the fiber material.
  • the nip between the feed roller and the impact roller is arranged within the width of the shafts.
  • the drawing shows a schematic cross section through a feed device.
  • the feed device has a vertical first shaft 1, in which the fiber material is contained.
  • the fiber material sinks under the influence of gravity. This downward movement of the fiber material is additionally supported by air pressure.
  • the transport air can exit at least one shaft wall 2 into an exhaust air chamber 3.
  • a driven feed roller 4 is arranged in an opening 3, which rotates counterclockwise in the exemplary embodiment.
  • the feed roller 4 is arranged approximately centrally under the first shaft 1.
  • the beater roller 7 can have beater bars distributed over its circumference, which for example carry a plurality of radially projecting needles.
  • the center distance of the feed roller 4 and the beater roller 7 is chosen so that the two rollers are no longer touching.
  • the verticals through the beater or feed rollers 4, 7 are offset from one another, the connection plane through the centers of rotation of the rollers being inclined relative to the vertical through the beater roller 7 by an angle between 15 ° and 90 °, preferably 45 °, in the direction of rotation of the beater roller is.
  • the nip between the two rollers is essentially within the shaft width of both the upper shaft 1 and the lower shaft 8, which is tangentially from the beater roller 7 substantially vertical, or slightly by 10 ° from the vertical through the upper one Shaft cross section protruding, coming off.
  • the beater roller 7 exerts a gentle clamping action on the fiber material, which is plucked into flakes, but not excessively mechanically stressed, and which essentially maintains its direction of movement, namely vertically from top to bottom.

Abstract

Un dispositif d'alimentation en cardes, rubans de cardes et similaires comprend un premier puits vertical (1). Un cylindre d'alimentation (4) agencé à l'ouverture inférieure du premier puits coopère avec un cylindre batteur (7) agencé sous le cylindre d'alimentation (4), qui tourne en sens contraire à ce dernier. Un deuxième puits (8) s'étend tangentiellement à partir du cylindre batteur (7). Le plan qui traverse les axes de rotation des cylindres d'alimentation et batteur (4, 7) forme un angle (α) compris entre 15° et 90° par rapport au plan vertical qui traverse l'axe de rotation du cylindre batteur (7), dans le sens de rotation de ce dernier.

Claims (4)

  1. Dispositif d'alimentation pour cardes, peignes et similaires comportant une première colonne verticale (1), à l'ouverture inférieure de laquelle est disposé centralement un cylindre d'alimentation (4), et un cylindre batteur (7), duquel part tangentiellement une seconde colonne inférieure (8) sensiblement verticale, caractérisé en ce que
    - le plan passant par les axes de rotation des cylindres d'alimentation et batteur (4, 7) est incliné suivant un angle (α) de 30° à 90° par rapport au plan vertical passant par l'axe de rotation du cylindre batteur (7) dans le sens de rotation du cylindre batteur, et
    - le cylindre d'alimentation (4) tourne dans le sens opposé à celui du cylindre batteur (7).
  2. Dispositif d'alimentation suivant la revendication 1, caractérisé en ce que l'angle d'inclinaison (α) du plan est compris entre 40° et 50°.
  3. Dispositif d'alimentation suivant la revendication 1 ou 2, caractérisé en ce que la seconde colonne (8) s'étend sensiblement dans le prolongement de la première colonne (1).
  4. Dispositif d'alimentation suivant la revendication 1 à 3, caractérisé en ce que le point de serrage entre le cylindre d'alimentation et le cylindre batteur (4, 7) est disposé dans les limites de largeur de section de la première et de la seconde colonne (1, 8).
