Definitions

  • the present invention relates to a cleaner shaft for spinning machines, for example cards, cards.
  • the material supply of the card has an influence on the end product of the card: the card sliver. Irregularities in the feed can be found in the tape, since they are responsible for the formation of thick or thin spots, c. q. cause the formation of thick or thin spots. These defects can hardly be corrected in the course of the remaining processes to produce a yarn and therefore have a direct influence on the final yarn quality.
  • the wadding that is formed in the feed shaft must be equally distributed across the width and of the same density.
  • One problem is the pneumatic flake feed, which feeds the individual card with flakes unevenly. This problem was solved by means of a shaft which was closed by a
  • Feeding device was divided into two parts, so that the actual cotton wool to the card is only locally influenced by this feeding device.
  • the shafts have been optimized with an improvement in the air balance and constructive improvements, it is
  • BESTATIGUNGSKOPIE mainly the cleaning machines, such as coarse cleaners or fine cleaners, are responsible.
  • the coarse cleaner is usually arranged at the beginning of the process directly after the bale opener, which removes the cotton from the bale and feeds it into the pneumatic transport.
  • the coarse cleaner is available in very different models, but they have some common features.
  • the material is mostly processed in free flight using roughly equipped work rolls. The opening effect is therefore low and, above all, coarse dirt that is present on the outside of the flakes is removed.
  • Coarse cleaners also remove free dirt particles, such as shell parts or other foreign bodies.
  • the fine cleaner comes much later in the process and is usually immediately upstream of the cards.
  • the fine cleaner is more aimed at removing dirt from inside the flakes. This cleaning step should therefore take place after an additional opening step.
  • the fine cleaner almost always works with a clamped feed and a finer assembly of the roller downstream of the feed.
  • the opening roller is equipped as a cleaning roller, for example with rust knives and a saw tooth set on the roller.
  • EP 810309 discloses a system concept in which the fine cleaner is integrated into the filling shaft.
  • the document discloses a filling shaft with several grate bars in accordance with the expansion in a fine cleaner.
  • This solution has the disadvantage that the arrangement of the grate bars is very complex and the space available in a filling shaft is smaller than that in a fine cleaner, which can result in either a lack of space or loss of functionality.
  • the disclosed arrangements have the main disadvantage that they are complex to construct and therefore expensive. In addition, they would not function reliably from a technological point of view.
  • the invention is based on the object of a device of the beginning to create the type described, which avoids the disadvantages mentioned, which in particular integrates the fine cleaning function in the filling shaft without taking over the complex construction of the fine cleaners.
  • the knife which is arranged directly after the transfer point, not only removes the dirt particles which are thrown outwards by the centrifugal force of the opening roller, but also the particles which are caused by the " combing effect "of the transfer point are released.
  • a guide element located in front of the knife directly after the transfer point, would push these released particles back onto the roller and thereby disadvantage the distance.
  • Direct means here also without elements arranged in between, which could have an influence on the separation movement of the dirt particles.
  • the range from 10 to a maximum of 190 ° with respect to the vertical line through the axis of rotation of the opening roller in the direction of rotation is preferably suitable for the arrangement of a discharge point.
  • the two discharge points are preferably arranged in such a way that trouble-free waste disposal is ensured and any impairments to the air balance are excluded.
  • the dirt discharge point hereinafter referred to as the separation point, is defined by the separation gap between the transfer point and the knife edge.
  • the transfer point is defined as the point where the smallest distance between the set of the feeding device and that of the opening roller is. This point is sometimes called the point of combing, here the fibers are taken over by the opening roller.
  • the distance between the transfer point and the knife edge expressed in the angle ( ⁇ ) between the transfer point and the knife edge, measured from the transfer point by the axis of rotation of the opening roller in the direction of rotation, is between 10 ° and 65 °, preferably between 10 ° and 45 °, especially between 20 ° and 32 °. This distance influences the opening of the discharge gap and thus the amount of waste and the composition of the waste.
  • the angle (ß) setting depends, among other things, on the length of the individual fibers and the degree of soiling.
  • the filling shaft can also be set to a minimum level by the knife, for the resolution of

  • the feed roller is preferably inclined (measured) at an angle ( ⁇ ) of 25 ° to 90 ° with respect to the opening roller by the axis of rotation of the feed roller and the opening roller relative to the vertical plane by the axis of rotation of the opening roller in the direction of rotation of the opening roller.
  • the fiber ejection point should preferably be arranged in such a way that the good fibers are ejected technologically. Since the fiber flakes are released at the transfer point, a long dwell time of the fibers on the opening roller is not technologically sensible, so a quick release has a rapid effect on the entire process.
  • a guide surface is arranged between the knife edge and the discharge point, which clearly separates the

  • the knife is preferably extended to the rear, as will be explained in more detail later.
  • the guide surface can run parallel to the radius of the roller surface, the distance to the roller surface can remain the same or open. Opening means that the distance between the two surfaces increases in the direction of rotation. As soon as the distance opens, the fibers are inclined to move outwards on the clothing so that they can be thrown off. This movement of the fibers is such that the discharge point is preferably arranged at an angle ( ⁇ ) of 40 ° to 55 ° (measured from the beginning of the opening through the axis of the opening roller in the direction of rotation). The beginning of the opening means the point where the distance from the guide element relative to the roll surface begins to increase. This opening preferably takes place directly after the knife edge, the discharge point is then arranged at an angle ( ⁇ ) of 40 ° to 55 °, measured from the knife edge through the axis of the opening roller in the direction of rotation.
  • the knife is preferably folded together with the guide element, which is arranged downstream.
  • the knife edge is due to the dirt particles and the fibers that brush over the edges have a high potential for wear. You can either choose a wear-resistant material and / or make the knife edge replaceable.
  • An alternative solution is to make the knife and guide element from one piece. Before this, a piece of sheet metal is first made to the desired thickness, the knife edge is ground and then the sheet metal is bent into the desired curvature. This creates a finer knife edge that has no additional

  • the degree of cleaning which can be achieved is influenced by the cleaner shaft according to the invention from the distance of the knife edge to the needle tips and from the distance of the knife edge to the transfer point.
  • This last knife setting can be adjusted manually or with the help of a drive.
  • the setting can take place at predetermined intervals or continuously.
  • the setting can be combined with a control which makes or adjusts the setting, preferably depending on the degree of soiling, fiber length or provenance.

This opens the gap between the element and the roller, which causes the fibers to be ejected.
