Definitions

  • the invention relates to an opening roller for a spinning machine.
  • Rolls equipped with sets are used in particular in spinning preparation, including the carding machine, in order to successively dissolve fiber flakes in such a way that, in the carding machine, a parallelization of the fiber flakes that have been broken down and cleaned into fibers is possible.
  • sensors and measuring technology have become more important as a means of detecting undesirable changes to the product, or in the course of the spinning process on the intermediate product, for the automatic production of a high-quality product.
  • dissolving is understood to mean, for example, the relatively slow feeding of a fiber wadding in a clamped state and the takeover of this delivered fiber wadding by means of a relatively quickly rotating roller provided with sets.
  • This process accordingly includes a clamping point, in which the fiber wadding is transferred in the clamped state and an acceptance point, at which the opening roller the fibers or. Detaches fiber flakes from the delivered fiber structure and combs them out in a certain sense.
  • An opening roller 1 (Fig. 1) has a roller body 2, which with fixed end walls 3 and. 4 is provided.
  • the end wall 3 is provided with a shaft bearing 16 and the end wall 4 with axle bearing 15.
  • the axle bearing 15 and the shaft bearing 16 are in turn each rotatably supported by a roller bearing 17 which is fixed in a machine housing part 18 and. 19 is embedded.
  • the opening roller 1 is rotatably mounted in a machine housing which is stationary per se.
  • a drive pulley 20 is mounted on the shaft bearing 16 and is driven by a drive belt 21.
  • the axle bearing 15 is used for rotatably receiving an axis 13 and the shaft bearing 16 for receiving a shaft 14, both of which are part of a clothing carrier roller 5.
  • This clothing support roller has a support cylinder 8 which is firmly connected to the end faces 11 and 12, the end face 11 in turn being firmly connected to the shaft 13 and the end face 12 being firmly connected to the shaft 14.
  • each clothing needle 6 is pivotally mounted in the corresponding hemispherical bearing recess 9.
  • cover plate 10 In order to keep the needle feet in the depressions 33, they are covered with a cover plate 10, but in such a way that the pivotability of the clothing needles 6 is retained.
  • the clothing needles 6 penetrate the roller body 2 through round holes (not marked) provided therein, each of which, seen from the clothing foot, is funnel-shaped Wells 33 are upstream. These recesses 33 allow the clothing needles to be pivoted in order to change the position of the clothing needles and thus their intensity.
  • This pivoting of the clothing needles 6 is done by the axial displacement of the shaft 14 in the displacement directions 34 and. 35.
  • the axial displacement of the shaft 14 takes place by displacing a displacement element 25 in that a sliding block 24 belonging to the displacement element 25 projects into an annular guide groove 23 of a guide wheel 22 connected to the shaft 14 and thus displaces the guide wheel 22 in the axial direction.
  • the displacement element 25 is in turn received by a displacement shaft 26 which is rotatably supported in a bearing support 27.
  • the shifting shaft 26 is rotated on a wheel disk 29, which is connected to a shaft 28 belonging to the thread 26.
  • the sliding thread 26 is secured against axial displacement by means of split washers 44.
  • the bearing support 27 is permanently assigned to a machine housing part 36.
  • the shaft 14 is provided with a guide wedge 31 which is guided in an axially directed guide groove 30 provided in the shaft bearing 16.
  • the guide groove 30 allows the shaft 14 to be displaced in the displacement direction 34 or. 35.
  • the said shifting causes a change in the angle ⁇ , i.e. causes the needle tips of the needle sets 6 to assume different angles ⁇ with respect to the peripheral surface of the roller body 2, as a result of which their intensity will change with respect to the fiber flakes to be dissolved.
  • Fig. 3 shows a variant of the opening roller of Fig. 1, which is why the same elements are provided with the same reference numerals.
  • the clothing support roller 5 is locked against axial displacement by spacer elements 37, which are located on the one hand between the end wall 4 and the end face 11 and on the other hand between the end wall 3 and the end face 12, but are rotatably supported by means of the axis 13 and the shaft 14 .
  • spacer elements 37 which are located on the one hand between the end wall 4 and the end face 11 and on the other hand between the end wall 3 and the end face 12, but are rotatably supported by means of the axis 13 and the shaft 14 .
  • a sliding sleeve 40 is provided, to which the guide wheel 22 is attached.
  • This sliding sleeve 40 is on the one hand axially displaceable on the shaft 14 in the directions 34.1 and 35.1, which is done by means of the guide wheel 22, as was described with reference to FIG. 1 for the shaft 14 (FIG. 2).
  • This sliding sleeve 40 serves as an intermediate member between the shaft bearing 16.1 and the shaft 14.1 and transmits the torque of the shaft bearing 16.1 to the shaft 14.1 by means of a wedge 41.
  • This wedge 41 is firmly embedded in the sliding sleeve 40 and is on the one hand in a spiral guide groove, which in the Shaft bearing 16.1 is provided and, on the other hand, is guided in an axially directed longitudinal groove 42, which is provided in the shaft 14.1. Characterized when moving the sliding sleeve 40 in the directions 34.1 respectively. 35.1 the shaft 14.1 rotates relative to the shaft bearing 16.1, which causes the change in the angle ⁇ .
  • spiral groove is shown only schematically with dash-dotted lines, while the longitudinal groove is shown with dashed lines.
  • the longitudinal groove is marked with 42 and the spiral groove with 43.
  • the wheel disc 29 can be driven either manually or by a servomotor 45 for moving the wedge 24, which drives the wheel disc 29 via an overdrive 46.
  • the servomotor 45 is controlled by a controller 47 on the basis of a predetermined signal.
  • the signal entered into the controller 47, on the basis of which the servomotor for changing the position of the clothing support roller 5 is controlled, can originate, for example, from an overall controller, as described, for example, in DE-39 19 746 by the applicant.
