Definitions

  • the invention relates to a carding element with a needle or tooth set, which is arranged at least on part of the circumference of a carding or cleaning roller.
  • the carding element is known as a stationary element, which has to be dismantled and replaced when the type or size of clothing is changed. Once a type or size of clothing has been defined, it usually remains for a long time.
  • the carding elements proposed in connection with the present invention provide further possibilities for realizing the aforementioned method.
  • the process takes into account the circumstances in today's spinning mills that, in contrast to earlier spinning mills, in which the ring spinning process was used as the only process for the production of staple yarns, in Recently, new spinning processes have been developed in different directions, which place different demands on the cleaning effect and the permissible fiber impairment in the cleaning of the cotton.
  • the task was therefore to find a solution for optimizing the degree of cleaning, taking into account the different demands made on the latter two variables by the corresponding spinning process, which is achieved with the process mentioned.
  • the solution according to the invention is that the carding element has more than one set or set size and can be moved such that a second or. other sets or sets sizes in working position and the other resp. the other types of clothing respectively. Set sizes can be set in the rest position.
  • Figures 1 and 2 show a carding or cleaning roller 1, which rotates in the direction of rotation 13 and is provided with a clothing 12 and is rotatably and drivably mounted (not shown) by means of a shaft 2.
  • a roller 3 is assigned a carding element 3 with a polygonal cross section, which is rotatably supported by means of a shaft 4.
  • the carding element 3 has on the four outer surfaces, one of which is opposite the circumference of the roller 1 and thus its clothing 12, a clothing 14.1, 14.2, 14.3, 14.4, starting from the clothing 14.1, which is the finest clothing, each The following set is coarser than the previous one and the set 14.4 is coarsest.
  • the carding element 3 is by means of the arrangement explained later with Figure 2 in the arrow directions 15 and 16 against respectively. Movable away from the roller 1 and rotatably arranged in the direction of arrow 17.
  • the sets 12 and 14 are shown as tooth sets. However, it is possible to provide a needle set instead of a tooth set, or any suitable set. It is also not necessary for the sets to be arranged in such a way that the teeth are directed towards one another, but there is also the possibility of arranging at least one set in the other direction or for both sets to be arranged in such a way that the tooth backs are directed towards one another. In the latter case, the roller 1 would rotate in the direction of rotation 18, for example.
  • FIG. 2 the arrangement shown is intended to show the possibility of the carding element 3 moving in the directions 15 and 16 and the rotation in the direction 17.
  • the shaft 4 is rotatably supported at both shaft ends in a bearing element 6, which further accommodates one eccentric 7 of an eccentric shaft 5 (see also FIG. 1).
  • bearing supports 9 each have a guide slot 8 in which the two free ends of the shaft 4 for the movement of the carding element 3 are guided in the directions 15 and 16.
  • a shaft extension 20 of the shaft end 10 is connected to a servomotor 21 which is able to rotate or hold the eccentric shaft 5, i.e. to fix the eccentric 7 in the company in a predetermined position.
  • the servomotor 21 and the two bearing supports 9 are each stationary on a machine housing part 11.
  • the right shaft end of the shaft 4 is connected by means of a shaft extension 22 to a further servomotor 23, which is used for movement in the directions 15 and 16 between two sliding surfaces 24, each part of which Support 25 are guided.
  • the supports 25 are arranged in a stationary manner on the machine housing part 11, analogously to the servomotor 21 and the supporters 9.
  • the servomotor 23 is used not only for rotating, but also for fixing the carding element 3 for operation.
  • the servomotors 21 and 23 are shown purely schematically and do not necessarily have to have the shape shown, but they can be, for example, geared motors with a strongly reduced planetary gear and shaft brake, or the servomotor 21 could be a spindle motor that drives the shaft extension 20 via a rack and one on the Drive shaft extension 20 mounted gear. would fix.
  • Servomotors are usually geared motors with high gear ratios, which have an additional brake to fix the position of a driven shaft in a predetermined position.
  • This turning in the direction of rotation 17 is not only required to the type of clothing, respectively.
  • FIGS. 5 and 6 show the more detailed structure of the carding element 3, in that a base element 26 is rotatably mounted on the shaft 4 and has four dovetail guides, which are identified by the numbers 27.1, 27.2, 27.3 and 27.4.
  • the dovetail guide 27.1 takes the assembly lamella 28.1 with the sets 14.1, the dovetail guide 27.2 Set fins 28.2 with the sets 14.2, the dovetail guide 27.3 Set fins 28.3 with the sets 14.3 and the dovetail guide 27.4 set fins 28.4 with the set 14.4.
  • FIG. 6 shows that spacer slats 29 are provided between the clothing slats in order to maintain a distance between the individual clothing slats.
  • FIG. 7 shows a variant of the carding element 3 of FIGS. 5 and 6 and is therefore labeled 3.1.
  • This variant has 6 surfaces to increase the number of different clothing sizes or types.
  • a concave curvature which is shown schematically in FIG. 5 with a dash-dotted line and identified by the arrow R, can also be given in this variant, this curvature generally concentric with the convex curvature of the clothing 12 of the roller 1 is selected.
  • FIGS. 8, 9 and 10 show a further variant of a carding element 3.2, in which the sets are not part of a firmly mounted set-up slat, but part of a chain link 30. However, the sets are, since they can be the same types of set as with the figures 1 to 6 shown, identified by the same reference numerals.
  • the chain links 30 form the chain 31 with the aid of chain link rods 32 which are continuous in the axial direction of the carding element 3.2. Between the individual chains 31, tubular spacers 45 are provided, which are also mounted on the rods 32.
  • spacers 45 are received in grooves 33 by sprockets 34, as is the case with a bicycle chain.
  • the chain wheels 34 are rotatably mounted on a continuous shaft 35.
  • the shafts 35 are at their two ends in a bearing plate 36, respectively. 37 rotatably mounted, one of the shafts being connected to a servomotor 38.
  • This servomotor is shown purely schematically in FIGS. 8 and 10, therefore what has already been mentioned for FIG. 2 applies.
  • the chains 31 are used to rotate the three other shafts, which are not driven separately by a servomotor.
  • the rods 32 are each at their free end in each end shield 36 or. 37 guided in a groove 40 provided in these end shields, which is endlessly shaped in such a way that the chain 31 forms the curvature with the radius R shown schematically with dash-dotted lines.
  • This curvature is, as shown in Figure 9, for the sets 14.1, 14.2, 14.3 and. 14.4 kept the same.
  • This curvature corresponds to the radius R. a curvature concentric to the axis of rotation (not shown) of the roller 1, provided that the distance between the clothing 12 of the roller 1 and the clothing of the carding element 3.2 in action is the same over the entire length section L.1 of the peripheral length of the clothing 12.
  • guides 46 can be provided for each chain section (only shown for one in FIG. 9), which carries a different set, which supports the bars 32 in absorbing the pressure caused by the radial forces.
  • FIGS. 9 and 10 it can be seen from FIGS. 9 and 10 that more than one carding element 3.2 can be provided and that before and after a carding element 3.2 or between two carding elements 3.2 a fiber fleece guide element is provided which holds the fleece lying on the clothing 12 of the roller 1 despite the centrifugal force , which acts on this fleece when the roller 1 is rotating, does not fling it away between two carding elements 3.2, but feeds it to the next carding element 3.2.
  • each carding element 3.2 it is possible to move in the directions of movement 15 and 16 and in the direction of rotation 17.
  • the bearing plate 36 has an axis 42 and the bearing plate 37 has a shaft 43. Both, that is axis 42 and shaft 43, are coaxial with the axis of rotation 45 of the end shields 36, respectively. 37 firmly arranged.
  • the means for realizing these linear movements 15 and 16 and the rotary movement 17 on the individual carding element 3.2 correspond essentially to the means shown and described with FIGS. 3-4, which is why the same means are identified with the same reference numerals, with the exception that is the shaft extension 44 of the shaft 43, which is connected to the servomotor 23.
  • FIG. 11 shows a further variant of a carding element, which is identified by 3.3.
  • the carding or cleaning roller 1 is only represented by its clothing 12, which for the sake of simplicity is also shown as a straight clothing.
  • the carding element 3.3 has a fixed needle set 50 and a movable needle set 51. Both sets are arranged in a housing 52 which is fixedly connected to a stationary machine part 54 by means of supports 53 and which extends in the longitudinal direction (not shown) over the width of the card and is rod-shaped when viewed from the outside.
  • the needles of the fixed clothing 50 are in a base plate 55, which is provided within the housing 52 such that the needles protrude from the housing 52 by a predetermined amount. Between the upper housing wall 56 of the housing 52 and the base plate 55, as seen in FIG. 11, the needles of the clothing 50 are inserted in a foam rubber mat 57, which serves to fill the space between the upper housing wall and the base plate 55 in such a way that no dirt and dust can accumulate in it.
  • the space filled up with the foam rubber 57 results from the choice of the long conical needles, specifically in order to obtain the possibility of varying the distance H with the same needle length, but not as a moving but adjustable element. This means that the needle tips of the clothing 50 can protrude to different extents from the upper housing wall 56.
