Definitions

  • the present invention relates to a storage of a Flexibeibogens in a revolving flat card.
  • the lid area together with the drum forms the main carding zone and has as function the dissolution of the flakes into single fibers, removal of impurities and dust, elimination of very short fibers, the dissolution of nits and the parallelization of the fibers.
  • hard covers, revolving lids or a mixture of fixed and revolving lids are used.
  • a revolving lids or a mixture of hard covers and revolving lids one speaks of a revolving flat card. Between the sets of covers and the clothing of the drum forms a narrow gap called the carding nip.
  • revolving lids by the revolving lids, guided by arcuate strips - so-called flexible arch, Regulierbogen, Flexbogen or Gleitbogen - are guided along a predetermined distance by these strips in the circumferential direction of the drum.
  • the size of the carding nip lies with a revolving flat card between 0.10 to 0.30 mm for cotton or up to 0.40 mm for man-made fibers.
  • the flexible bend is secured to the machine frame with adjusting screws.
  • the adjusting screws allow a concentric adjustment of the surface of the flexible bend so that the traveling lids can be guided along the drum surface at a constant distance.
  • the setting accuracy depends on the design of the adjusting screws.
  • the flexible sheet is supported on rotatably mounted rollers.
  • the rollers are designed as rotatable helical cams. Upon rotation of these cams is raised by the worm shape of the flexible bend at the corresponding support point and in the radial direction away from the drum axis or to these. In this way, a coarse adjustment of the carding nip is proposed.
  • the flexible sheet itself is moved in the drum rotation direction, which causes the radial distance of the flexible sheet to change from the drum axis.
  • a disadvantage of the device is that the entire flexible sheet must be moved to adjust the carding gap.
  • the fine adjustment is provided by the movement of the flexible bend, which is associated with a considerable expenditure of force and thus only jerking can be performed.
  • the invention of the present application has for its object to provide a storage of a flexible sheet, which allows an exact fine adjustment of the carding nip, without changing the position of the flexible sheet in the direction of rotation of the drum.
  • Another object of the invention is to provide a bearing which eliminates the need to adjust the setting to compensate for thermal expansion of the drum.
  • a storage of a flexible sheet is proposed in a revolving flat card with a drum and a drum axis, wherein the bearing comprises at least three bearings, each with an eccentrically mounted bolt, and the flexible sheet is held at each bearing point on the eccentric bearing bolts such that is moved radially to the drum axis during a rotational movement of the bolt, the flexible sheet.
  • a setting device spaced from the bolt is provided and this adjusting device connected at a point of articulation via a lever with the bolt such that in a linear displacement of the articulation point in the adjusting device on the lever, a rotational movement of the bolt is caused.
  • the flexible bend is supported on the machine frame.
  • bearings are provided.
  • the number of bearings depends on the design of the flexible sheet, in particular its length.
  • the bearing can be arranged symmetrically or asymmetrically with respect to the flexible bend.
  • more than three bearing points for example five or seven bearing points, are necessary. In this case, the storage of the flexible sheet takes place in such a way that the traveling lids sliding thereon are guided along in the desired manner of the drum surface.
  • the flexible sheet is held at each bearing by a bolt.
  • the flexible bend rests on the bolt.
  • the bolt is held by an axle in the machine frame with the bolt being eccentrically attached to the axle.
  • the bolt can also be made in one piece with the axle.
  • the arrangement is also conceivable vice versa, so that the bolt is mounted in the machine frame and the axis of the bolt is used to support the flexible bend. If the bolt or its axis undergoes a rotational movement, this causes a radial displacement of the support point relative to the drum axis and thus of the flexible bend due to the eccentric mounting of the bolt.
  • the bolt can be freely rotatable or be arranged in its position relative to the machine frame adjustable. It is also conceivable that the bearing of the bolt itself is made adjustable in order to adjust a coarse adjustment of the distance from the support point of the flexible sheet to the axis of the drum during assembly can.
  • the bolt is connected via a lever to a setting device spaced from the bolt.
  • the adjusting device is connected at a point of articulation via the lever with the bolt such that upon a linear displacement of the articulation point in the adjusting device via the lever, a rotational movement of the bolt is caused.
  • This rotational movement of the bolt causes a radial displacement of the support point of the flexible bend and thus an adjustment of the carding gap.
  • the lever is rotatably connected to the bolt, so that a pivoting movement of the lever through the fixed axis of the bolt leads to a rotational movement of the bolt. Due to the eccentric arrangement of the bolt, the radial distance of the support point of the flexible sheet from the drum axis is changed during a rotational movement.
  • the bolt is round or represents only a circle segment, as long as the support point of the flexible bend is displaced on the bolt by a rotation of the bolt radially to the drum axis.
  • the same effect is achieved when the lever is rotatably connected to the axis when the axis is not provided fixed, but rotatably connected to the bolt.
  • the embodiment of the bolt in particular the geometric shape of the outer contour and the eccentricity determined thereby, respectively, the radial distance of the support point with respect to the drum axis, which is changed by the rotational movement of the bolt, must be carried out according to the adjustment possibilities to be achieved.
  • a bolt with variable eccentricity To obtain a shape independent of the starting position of the bolt after the coarse adjustment of the flexible bend, use a bolt with variable eccentricity. If, however, a circular outer contour of the bolt is used with a fixed eccentricity, results depending on the position of the bolt a different-sized displacement of the support point at a same large rotational movement of the bolt.
  • a bolt with a variable eccentricity corresponds to a spiral outer contour. Contrary to a circular design, a helical design of the outer contour of the bolt results in a linear dependence of the radial displacement of the support point of the flexible bend to the angle of rotation of the bolt. As a result, the initial position of the bolt after the coarse adjustment of the flexible sheet is irrelevant and it results for all bearings the same radial displacements of the support points upon rotation of the bolt by a certain angle.
  • the adjusting device may comprise, for example, an adjusting screw with a screw axis.
  • the articulation point can be formed by a component provided with an internal thread through which the adjusting screw is guided.
  • the lever is connected at one end to the bolt and at the other end to the component forming the articulation point.
  • the connection with the component is advantageously designed as a joint.
  • the rotation of the adjusting screw causes the linear displacement of the articulation point or of the component along the screw axis. This results in a pivoting movement of the lever, which in turn has a rotation of the bolt result.
  • the adjusting device comprises a biasing means, wherein the biasing means is arranged such that a play-free displacement of the articulation point takes place in the adjusting device.
  • the biasing means is, for example, a compression spring which is installed between the machine frame in which the adjusting device is held, and the articulation point-forming component, the component in the screw thread is fixed such that the flanks of the internal thread of the component on one side of the flanks of the external thread Adjusting screw to be pressed. In this way, a play-free displacement of the component or the articulation point on the screw axis is possible by turning the adjusting screw.
  • such an arrangement of a compression spring has the advantage that a fraction of the compression spring causes a radial displacement of the flexible sheet away from the drum axis. As a result, a failure of the compression spring does not cause the moving lid can touch the drum surface by unintentional lowering of the flexible arch.
  • a tension spring is provided with a corresponding arrangement of the device.
  • Other biasing means which allow a backlash-free movement of the articulation point can be used, for example pneumatic or hydraulic elements.
  • a backlash-free displacement of the component, respectively the articulation point, on the screw axis can also be achieved by the use of elastic threaded sleeves as a biasing means.
  • the component and the biasing means form a unit, which is an elastic threaded sleeve.
  • Elastic threaded sleeves are made such that they are held on the adjusting screw under a residual stress.
  • Elastic threaded sleeves for example, have two independent internal threads, which are manufactured under a bias and are forced apart by a screw. This creates a tension between the two threads, which leads to a play-free movement of the threaded sleeve on a screw.
  • the adjustment device comprises a temperature compensation sleeve, which in addition to the rotation of the adjusting screw causes a linear displacement of the articulation point along the screw axis to compensate for a temperature-induced expansion of the drum via a corresponding radial displacement of the flexible bend.
  • the temperature compensation sleeve is arranged in the adjustment device such that the sleeve can expand or contract even when heated. This temperature-induced change in the length of the temperature compensation sleeve also causes a linear displacement of the deflection point along the screw axis.
  • the length of the temperature compensation sleeve and the material of the Terrperaturaus remplise is dimensioned such that their expansion causes a radial displacement of the flexible sheet in the same order of magnitude, as the drum expands at the same temperature change.
  • a manual or programmed adjustment in the temperature-induced expansion of the drum is no longer necessary.
  • the adjustment device is thus self-adjusting with respect to temperature compensation. This has the advantage that the adjustment of the flexible bend in the cold state of the machine can be made and after warming up the machine no adjustment is required. The differences in temperature between the Drum surface and the installation of the adjustment is taken into account in the design of material and length of the temperature compensation sleeve.
  • the eccentricity of the bolt is in such a ratio with the length of the lever that one revolution of the adjusting screw causes a radial displacement of the flexible elbow from 0.1% to 10% of a thread pitch provided on the adjusting screw. If, for example, the thread pitch of the adjusting screw is provided at 2 mm per revolution and the ratio is set at 1.0%, a complete revolution of the adjusting screw causes a radial displacement of the flexible sheet by 0.02 mm.
  • the ratio between the lever length and the eccentricity of the bolt and the pitch of the thread of the adjusting screw is dimensioned such that a complete revolution of the adjusting screw leads to a radial displacement of the flexible sheet of 0.01 mm.
  • the flexible bend can be adjusted by 0.0025 mm with a quarter turn of the adjustment screw. This is advantageous, for example, in the case of re-grinding of the trims of the revolving covers or the compensation of already slight signs of wear. A given carding gap can be maintained exactly, which leads to a consistent quality of the carding.
  • a releasable blocking of the displacement of the articulation point for fixing a basic setting is provided in an advantageous embodiment of the invention.
  • the attachment point is held in the adjustment via a determination of the lever.
  • the bolt or its axis is rotated until the flexible sheet is roughly adjusted. Subsequently, the lever or its axis is fixed to the bolt and the blocking released. This ensures that regardless of the basic setting always the same Feinverstellpotential the adjuster is present in both directions.
  • At least at one bearing point of the Flexibelbo-gene with the bolt in operative connection that the flexible sheet can not lift off the bolt.
  • This can be achieved by the bolt from the flexible bend is covered on two sides.
  • the bolt can be held in a arranged in the direction of rotation of the drum slot of the flexible bend.
  • Another possibility forms a tension of the flexible bend at the location of storage with the machine frame, for example by means of a spring or a spring-loaded tie rod.
  • a displacement means is arranged, wherein the flexible sheet is simultaneously displaceable over the displacement means in all bearing points radially to the drum axis.
  • the displacement means is designed such that, as a result of the movement thereof, a distance between the bolt and the flexible bend changes radially with respect to the drum axis.
  • the displacement means may for example be designed as a top of the bearings away leading sheet metal strip.
  • the metal strip is ground in each case in the region of a bearing with a uniform thickness change, so that changes in movement of the metal strip in the direction of rotation of the drum axis, the distance between the support point of the bolt and the flexible bend. Since such a metal strip is moved by all bearings simultaneously, learns the Flexibelbogen in its entirety a simultaneous adjustment of the radial distance to the drum axis at all bearings.
