Definitions

  • the invention relates to a disintegration roller for a spinning machine, for the disintegration and cleaning of cotton fibers, with a predetermined number, on the circumference of the disintegration roller and attached to it, for the detection and disintegration of cotton flakes.
  • opening rollers are known, for example, in so-called coarse cleaning machines.
  • the applicant sells such a machine worldwide under the brand name mono roller cleaner B4 / 1.
  • the applicant has registered another patent of this type in Switzerland under number CH - 00321 / 89-0.
  • Both machines have striking elements distributed around the circumference of the opening roller, which consist of a round bolt fastened radially to the circumference of the opening roller. Such bolts are attached to the circumference in a predetermined distribution.
  • the two aforementioned machines work in a manner in which the material is input at one axial end of the opening roller and gripped by the striking elements, brought over cleaning grate bars and gradually brought to the other axial end of the opening roller by means of steering chambers in order to use the centrifugal force to to convey dissolved fiber flakes through the outlet of the machine.
  • FIGS. 1 and 2 The latter cleaning machine, registered in Switzerland under the aforementioned number, is shown semi-schematically in FIGS. 1 and 2 in order to be able to explain the principle later on the basis of this illustration.
  • Efficient dissolution means an increased dissolving of large fiber flakes into as many small ones as possible, namely according to the principle of cotton cleaning, in which cleaning primarily means dissolving the flakes in fibers in order to better remove the dirt adhering to and between the fibers can.
  • the striking elements no longer have simple surfaces which are directed radially to the axis of rotation of the opening roller, but in that according to the invention the striking elements have surfaces which are inclined to the surface of the opening roller which receives the striking elements.
  • the advantage of these striking elements according to the invention is that the fiber flakes are less by means of strikes transported, but are detected by means of the striking elements in a small part of the fiber bundle and that the fiber bundle is then dragged in a flag-like manner through the ambient air, whereby the chance is increased that the flag-like fiber bundle due to the tendency of the fiber bundle to be retained by the ambient air into smaller parts is resolved as by the aforementioned hitting by means of the prior art bolts.
  • a prerequisite for good cleaning in such a machine is that the fiber bundle remains on the striking element for as long as possible and is pulled by means of it over the cleaning grate, i.e. the lowest possible ralative speed between the fiber bundle and striking element is created as long as the fiber bundle is pulled over the cleaning grate .
  • the fiber bundle should come again from the striking element after the cleaning grate in order to be transported one step in a transfer chamber described later in the axial direction of the opening roller and then to be caught again by further striking elements, until the fiber bundle strikes the machine at the other axial end the opening roller is reduced and cleaned again.
  • Figure 1 shows a cleaning machine 1 with an opening roller 2, which is rotatably and driven.
  • Impact elements 3 are attached to the opening roller in a predetermined distribution, seen in the circumferential direction as well as in the axial direction of the opening roller, radially to the axis of rotation of the opening roller.
  • the cleaning machine also has a cleaning grate 4, which is composed of individual grate bars 5, which are at least partially provided on the circumference of the opening roller, with a predetermined distance from the end faces of the striking elements 3.
  • the cleaning machine above the opening roller as seen in FIG. 1, has chamber walls 6 which, as shown in FIG. 2, are arranged obliquely to the axial direction of the opening roller in order to thereby delimit guide chambers (not marked).
  • guide chambers In these guide chambers, the fiber flakes fed in are conveyed when the opening roller rotates in direction D in the axial direction of the opening roller until the released fiber flakes leave the cleaning machine again through outlet 8.
  • the striking elements 3 shown in FIGS. 1 and 2 are also known from the aforementioned mono-roller cleaners and are accordingly state of the art.
  • FIG. 3 now shows a striking element 3.1 according to the invention, which has a mandrel 10 and a mandrel 11, which together with a fastening loop 12 form a double-hook-shaped element.
  • the fastening loop 12 is used to fasten the striking element 3.1 on the opening roller 2 by means of a screw 13.
  • the mandrel 10 like the mandrel 11, has an angle ⁇ with respect to the surface of the opening roller 2. With the help of this inclined position, the inclination of the surfaces of the striking elements to the surface of the opening roller mentioned at the beginning is created.
  • FIG. 3 shows that the mandrels 10 and 11 have a predetermined diameter D.
  • This diameter can vary between 4 to 8 mm, but is preferably 5 mm in size, using a hardenable round steel wire for producing these striking elements.
  • Spring steel should preferably be used.
  • the mandrels 10 and 11 have a predetermined angle ⁇ to the tangential plane E, which is perpendicular to the fastening axis B of the screw 13 directed radially to the opening roller axis.
  • the angle ⁇ is approximately 90 °, so that the mandrel 10 and 11 is inclined by an angle ⁇ in the direction of rotation D with respect to the radius A of the opening roller cross section.
  • the choice of the angle ⁇ can vary depending on the flake size and flake material to be cleaned and must in principle be determined empirically.
  • a striking element 3.2 can have only one mandrel 14, which, as shown with Figure 4, is attached to the opening roller 2 and an angle ⁇ or. ⁇ can have as shown in Figure 5.
  • Figures 6 to 8 show variants of the striking elements of Figures 3 to 5.
  • a striking element 3.3 each has a mandrel 16 and 17, which is chosen in diameter D to be the same as the mandrels 10 and 11 of the striking element 3.1, but additionally has a kind of flame-shaped bend, which are identified by R.
  • the other parts correspond to the striking elements 3.1, which is why they are provided with the same reference numerals.
  • bends have the purpose of increasing the inclination of the angle ⁇ in places and then reducing it, so that fibers which are from the mandrel 16 or. 17, close to the surface of the opening roller 2, on the surface opposite the surface of the opening roller are detected via this undulating "slide" against the free end of the mandrels 16 and 16 respectively. 17 slide and are braked according to the bends R.
  • the striking elements 3.3 and 3.4 can also be combined in the manner explained for FIGS. 3 to 5.
  • FIGS. 9 to 11 show, with the striking element 3.5, a variant of the striking element 3.1 of FIG. 3 in that the mandrels 19 and 20 are each provided with notches 22 which are open towards the surface of the opening roller 2.
  • the other parts correspond to the striking element 3.1, which is why they are provided with the same reference numerals.
  • the impact element 3.6 which represents a variant of the impact element 3.2 in FIG. 3, the notches 22, as shown in FIGS. 9 and 11, are open in the direction of rotation D of the opening roller.
  • striking elements are not limited to the use of steel wire, as are they are not limited to the use of a round cross-section, other types of profiles could also be used which are aerodynamically more favorable than the round profile, for example a profile similar to the wing profile.
  • opening roller is not restricted to the cleaning machines described; such striking elements could also be used on rollers which are used in bale release devices.
  • the prior art for such opening rollers in bale-dissolving machines generally consists of toothed rollers which form a toothed roller body, which loosens fiber flakes from the surface of fiber bales and transfers them to a pneumatic transport.
