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, which cooperates with an oppositely rotating impact roller arranged below the feed roller, and with a second shaft tangentially extending from the impact roller.
  • the fiber material is fed under the action of gravity and with air pressure support from a first shaft, designated as 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.
  • Under- Half of the feed roller is a rotating impact roller, which has blow bars on its circumferential surface. This impact roller, which rotates in the same direction of rotation as the feed roller, not only cuts off fiber material from the periphery of the feed roller, but its blow bars move from the region 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 opening edge, 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.
  • a roll of the dissolved fiber flakes can occur in the area of the beater roller on the shaft wall, which can lead to undesired agglomerations.
  • the invention is based on the object of providing a feed device of the type mentioned at the outset, with which rolling of the fiber material along shaft walls is prevented and less stress on the fiber material is ensured.
  • the features of the main claim serve to solve this problem. If the plane is inclined by the axes of rotation of the feed and beater roller, namely from at least 15 ° to approximately 90 ° with respect to the vertical plane through the center of the beater roller, and inclined in the direction of rotation of the beater roller, it is ensured that the flake material almost straight from the first shaft to the second shaft, whereby the fiber flakes cannot roll on shaft walls in the area of the impact point and can thus clump together into new tufts of flakes. In addition, it is achieved that the fiber material is treated in a highly gentle manner. The arrangement of the rollers enables a compact construction of the feed device.
  • the feed roller is arranged essentially centrally in the shaft cross section at the end of the first shaft.
  • the second shaft essentially extends 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 while protecting the fiber material as much as possible.
  • the nip between the feed roller and the beater roller is preferably 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 arranged 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 selected so that the two rollers are no longer in contact.
  • the verticals through the beater or feed rollers 4, 7 are offset from one another, the connecting plane being inclined in the direction of rotation of the beater roller by an angle between 15 ° and 90 °, preferably 45 °, relative to the vertical axis of the rollers relative to the vertical through the beater roller 7 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 essentially vertical, or slightly at 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 (alpha) 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.
