Definitions

  • the present invention relates to a turntable and a method for producing the turntable for a spinning machine, in particular track or card, for filing a sliver in a jug, with a base body and arranged in the base body band channel.
  • a turntable of a spinning machine in particular track, carding or comber, known.
  • the turntable and a sliver to be processed in the machine come into contact with each other.
  • a underside surface of the turntable coming into contact with the sliver has an at least partially spatial structure of elevations and depressions, wherein the elevations are honeycomb-shaped.
  • the spatial structure generally serves to reduce the friction between them upon contact of the turntable with the sliver. Too high a friction leads by a rotational movement of the turntable to a pulling of fibers of the sliver, which is stored in a container. Such entrainment can lead to uncontrolled depositing and damage to the sliver.
  • the object of the invention is therefore to provide a spatial structure on a turntable, which reduces the friction between the turntable and the Fa- Serband reduced and thus prevents entrainment of fibers of different fiber materials with different properties.
  • the object is achieved by a turntable for a spinning machine and a method for producing the turntable according to the independent claims.
  • Proposed is a turntable of a spinning machine, in particular a track or card, for filing a sliver in a jug, with a base body and arranged in the base body band channel.
  • the pot facing side of the turntable at least partially on a coating with a spatial structure of spherical, irregular elevations.
  • the intended use of the turntable is generally that the turntable is arranged above the pot and thereby performs a rotational movement about a vertical axis.
  • the pot is usually a cylindrical container, which is closed at the bottom. Through an upper opening of the pot sliver is placed in the pot.
  • the band channel is arranged, through which the sliver runs and is deposited down into the pot.
  • the coating comes into contact with the sliver already laid in the pot. Due to the special coating with the spatial structure of spherical, irregular elevations the entrainment of fibers of the sliver is prevented by the turntable. Due to the spherical, irregular elevations, the contact surface between the coating and the sliver is reduced because only one upper portion of the spherical elevation comes into contact with the sliver and exerts only a small amount of friction on the sliver.
  • the coating is arranged on the base body and / or a cover, wherein the cover is fastened to the side of the base body facing the jug.
  • a coating directly on the base body accelerates the manufacturing process, reduces the cost of materials and thus saves a total of manufacturing costs.
  • the coating is first arranged on a separate cover. This simplifies the manufacturing process, since only the cover for the coating process is required and the cover must then be attached only to the body. Also, so the cover can be removed for repair purposes or completely replaced.
  • An additional advantage is when the cover glued to the body, screwed with this and / or is rolled with a protruding over the main body edge in a groove on the body. Gluing can be used to save manufacturing costs.
  • a gland is used when the cover is to be releasably attached to the body. And a curling of the protruding edge in a groove on the body is easy to perform with a machine.
  • the coating is formed in sections on the base body and / or the cover, in particular spaced from the edge on which the cover is rolled. Thus, costs can be saved because only a smaller area of the cover and / or the body are coated. In addition, it is ensured that by forming after the coating, the coated area is no longer deformed and thus the coating is not damaged. Moreover, it is advantageous if the coating is formed from at least one base layer, structural layer and / or cover layer. A base layer is generally needed to form a defined substrate for the structural layer. For example, the base layer compensates for coarser unevenness of the base body and forms a smooth surface onto which the structural layer can be applied.
  • the structural layer forms the spatial structure of spherical, irregular elevations.
  • the cover layer is applied to protect the structural layer from wear.
  • a protective overcoat over the structural layer it is e.g. conceivable form the structure layer of a softer material, so as to simplify the manufacturing process.
  • base layer, structural layer and / or cover layer are formed of different materials.
  • base layer and / or a cover layer can also be dispensed with.
  • the coating is formed of chromium and / or a chromium alloy, this also brings advantages.
  • the coating of such a material is particularly resistant to wear.
  • the chrome and / or chromium alloy can be easily cleaned or polished.
  • the elevations have an extension in the range of 0.1 ⁇ to 10 ⁇ , in particular 0.6 ⁇ to 4 ⁇ .
  • an effect on the sliver of the known from nature lotus effect is similar.
  • the spaces between the surveys are too small for that the fiber band or its fibers can get caught between them. This prevents entrainment of the fibers of the sliver through the interstices.
  • the elevations are arranged and dimensioned such that an air cushion can form in the interspaces. This air cushion can also extend over the elevations, so that the sliver comes into contact with the coating only indirectly by means of the air cushion. The air cushion eventually leads to a reduction in sliding friction and entrainment is prevented.
  • a coating with a spatial structure of spherical, irregular elevations is applied to the, on intended use of the turntable, the can side facing the turntable.
  • a particular advantage in this case is when the coating is arranged on the base body and / or a cover, wherein the cover is attached to the side of the base body facing the jug. Placing the coating on the body results in cost savings through material savings and faster manufacturing. If, however, the coating is applied to the cover, this leads to a simpler coating process, since only the cover for the coating process is needed. Subsequently, the cover can be fixed by simple steps on the body. Moreover, it is advantageous if the cover is glued to the base body. The gluing is a simple and fast process, since neither the cover or the body have to be treated by several steps.
  • the cover can also be screwed to the base body. This method can be used to cover the cover e.g. for maintenance purposes. This also makes it possible to replace the complete cover.
  • the advantage here is that the rolling can be easily done with a machine and so also production time and costs are saved.
  • the coating is formed in sections on the base body and / or the cover, in particular is formed spaced from the edge, on which the cover is rolled.
  • costs can be saved because only a smaller area of the cover and / or the body are coated and damage to the coating during the forming of the cover is prevented.
  • the coating is formed from at least one base layer, structural layer and / or cover layer.
  • the base layer serves as a substrate for the structural layer.
  • the base layer also has the purpose of compensating for any imperfections in the underlying material of the body or cover.
  • the base layer forms a smooth surface for the structural layer.
  • the structural layer contains the spatial structure of spherical, irregular elevations and is subsequent to the base layer on these are applied.
  • a final topcoat is applied last, and serves to "seal" or generally protect the structural layer from external influences.
  • the methods for applying the respective layers are the following.
  • the base layer may be applied by a conventional electroplating process.
  • a gas separation process, chromating or other processes with which a suitable base layer can be produced are also conceivable.
  • the application of the structural layer is carried out in a sealed reactor.
  • the method of galvanic chromium deposition is also used.
  • the properties of nucleation processes are exploited.
  • germ cells gradually form, which grow spherically with the duration of the process.
  • the irregular structure of the surveys comes about through a random emergence of the germ cells on the base layer.
  • the extent, distribution on the surface, growth rate or the like of the bumps can be controlled.
  • the temperature inside the reactor influences the growth rate of the surveys.
  • Reproducibility of the structural layer is then achieved by setting the same physical parameters for each process. By this method, next to a high dimensional accuracy is achieved.
  • a cover layer is finally applied by various methods similar to those of the base layer. It should be noted here that the cover layer is not applied too thick, otherwise the desired elevations (and the recesses in between) are compensated by the cover layer. If the coating is formed of chromium and / or a chromium alloy, this also brings advantages. The benefits of "chrome plating" are wear resistance and resistance to various aggressive gases and liquids.

  • the coating 6 has three individual layers, namely a base layer 8, a structural layer 9 and a cover layer 10.
  • the base layer 8 adjoins the substrate material 7 and serves, for example, as a carrier layer for the structural layer 9 or compensates for unevenness of the substrate material 7.

  • the cover layer 10 closes off the coating 6 to the outside.
  • FIG. 2b shows a similar cross section of the coating 6 as in FIG. 2a.
  • the same components as in FIG. 2a are not discussed here.
  • the protrusions 11 are less densely disposed on the base layer 8, i. the number of elevations 11 per unit area is less than in FIG. 2a.
  • two elevations 1 1 may have a distance which may be in the range of several orders of magnitude of an average elevation 1 1. If an average elevation 1 1 has an extension in the range of, for example, 5 ⁇ m, then the distance between in each case two elevations 11 can be, for example, 50 ⁇ m. But it is also conceivable that the distance between each two elevations 1 1 only a fraction of the extension of a survey 1 1 has.
