Definitions

  • the invention relates to a method for delivering, removing and combining a pile of fibers emerging from a carding machine, which consists of a pair of rollers, which is formed into a fiber band and drawn off in a pile hopper and comprises an advantageous device for carrying out the method.
  • the fiber web leaves the delivery plant, e.g. B. the squeeze rollers, crosses a free space and is combined in a pile funnel to form a sliver which is drawn off by take-off rollers.
  • the fibrous web has a triangular shape on the way from the rollers of the delivery plant to the pile hopper.
  • the outer edges of the fiber web are regularly particularly susceptible to tearing.
  • high production e.g. B. of more than 50 kg / h
  • the merging of the pile is no longer sufficient. It has been shown that a strong air suction in the direction of the fiber web occurs increasingly towards the edges of the fiber web.
  • the edges of the fibrous web break out downwards, s6 that this creates the risk of tearing the fibrous web during high production.
  • the invention is therefore based on the object of creating a method of the type mentioned at the outset in which tearing of the fibrous web, in particular in the region of the edges of the fibrous web, is avoided.
  • the invention is based on the idea of letting the fibrous web fall into the pile funnel by itself when it is drawn off.
  • edges of the fibrous web which are under a lower tensile stress, fall into the pile funnel.
  • this component is avoided according to the invention in that the fiber pile is pulled off obliquely or vertically downwards.
  • An advantageous device for carrying out the method with a supply unit for the fiber pile, a pile funnel and a pair of take-off rollers for pulling off the sliver is characterized in that the pile funnel with the take-off rollers are arranged obliquely or vertically downward with respect to the delivery rollers of the supply unit.
  • the delivery rollers are advantageously not arranged vertically one above the other.
  • the pile funnel with the take-off rollers is expedient in the direction of emerging from the roller gap the F aserflors arranged.
  • the delivery rollers and the pile hopper with the take-off rollers are preferably arranged obliquely. It can also be advantageous that the delivery rollers are arranged horizontally and the pile hopper with the take-off rollers are arranged vertically below.
  • the distance between the delivery unit and the guide element is larger than the containment zone between the pair of rollers of the delivery unit and the guide surface of the guide element.
  • the guide element is attached in front of the pile funnel and serves to increase operational safety.
  • the guide element can consist of a flat plate with an opening.
  • the guide element can also be curved or slanted.
  • the fiber web is pulled into the pile funnel through the opening.
  • the opening can be praise or a gap between two guide surfaces.
  • the guide surface of the guide element is preferably aligned horizontally and arranged vertically below the rollers of the delivery mechanism.
  • the distance between the guide element and the delivery plant can be changed so that this guide element can also be brought in close proximity to the delivery plant.
  • the guide element can also be designed to be displaceable together with the pile hopper and the take-off rollers.
  • the guide element for the removal of shell parts or the like can also be perforated.
  • Figure 1 shows schematically a card in side view, in which a feed roller 1, a licker-in 2, a drum 3, a pickup 4 and a doctor roller 5 are arranged in the working direction.
  • a feed roller 1, a licker-in 2, a drum 3, a pickup 4 and a doctor roller 5 are arranged in the working direction.
  • two rolls 6, 7 of a delivery unit lying horizontally next to one another are arranged.
  • a pile hopper 8 and take-off rollers 9, 10 are provided vertically below the rollers 6, 7.
  • the rollers 6, 7 are arranged obliquely, ie the line through the centers of the rollers 6, 7 forms an angle to the vertical.
  • the pile hopper 8 and the draw-off rollers 9, 10 are arranged at a distance from the rollers 6, 7.
  • the rollers 6, 7 are arranged vertically one above the other.
  • FIG. 4 corresponds to that in FIG. 1, but between the rollers 6, 7 and the pile funnel 8 there is a guide element 11 directly adjacent to the rollers 6, 7 arranged.
  • the guide element 11 consists of a flat plate, in the middle of which an opening 12 is provided for the passage of the sliver.
  • Figure 5 corresponds to Figure 4, but the guide element 11 is in one Distance to the rollers 6, 7 arranged immediately adjacent to the pile hopper 8. While the guide element 11 according to FIGS. 4 and 5 is permanently installed, FIG.
  • FIG. 6 shows an embodiment in which the guide element 11 is designed to be displaceable into position 11a (dashed line).
  • the guide element 11, the pile funnel 8 and the draw-off rollers 9, 10 are arranged so as to be displaceable into the positions 11a, 8a, 9a and 10a.
  • the rollers 6, 7 are followed by a guide element 11c with curved guide surfaces.
  • the rollers 6, 7 are followed by a guide element 11d with beveled guide surfaces.
  • FIG. 10 shows an embodiment in which the guide element 11e is bent up laterally.
  • a two-part guide element 11 is arranged between the rollers 6, 7 (only roller 6 shown) and the pile funnel 8.
