Definitions

  • the present invention relates to a turntable and a method for producing the turntable for a spinning machine, in particular a draw frame or card, for storing a sliver in a can, with a base body and a belt channel arranged in the base body.
  • a turntable of a spinning machine in particular draw frame, card or combing machine
  • the rotary table and a sliver to be processed in the machine come into contact with each other during machine operation.
  • An underside surface of the turntable that comes into contact with the sliver has an at least partially spatial structure of elevations and depressions, the elevations being honeycomb-shaped.
  • the spatial structure generally serves to reduce the friction between the sliver when the turntable contacts it. Excessive friction leads to a pulling of fibers of the fiber sliver, which is stored in a container, due to a rotary movement of the turntable. Such dragging can result in uncontrolled laying down and damage to the sliver.
  • the object of the invention is therefore to provide a spatial structure on a turntable, which has the friction between the turntable and the sliver reduced and thus prevents dragging 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.
  • a rotary table of a spinning machine in particular a draw frame or card, is proposed for depositing a sliver in a can, with a base body and a belt channel arranged in the base body.
  • the side of the turntable facing the can has at least partially a coating with a spatial structure made of spherical, irregular elevations.
  • the intended use of the turntable is generally that the turntable is arranged above the can and thereby performs a rotary movement about a vertical axis.
  • the jug is usually a cylindrical container, which is closed at the bottom. Sliver is placed in the jug through an upper opening in the jug.
  • the band channel is arranged, through which the sliver runs and is deposited down into the can.
  • the coating comes into contact with the sliver already placed in the can.
  • the special coating with the spatial structure of spherical, irregular elevations prevents the fibers of the sliver from being pulled along by the turntable.
  • the spherical, irregular elevations reduce the contact area between the coating and the sliver, since only one the upper area of the spherical elevation comes into contact with the sliver and exerts only a slight friction on the sliver.
  • the coating is arranged on a cover, the cover being fastened to the side of the base body facing the can.
  • a coating directly on the base body accelerates the manufacturing process, reduces the cost of materials and thus saves overall manufacturing costs.
  • the cover is glued and / or screwed to the base body.
  • the cover is rolled into a groove on the base body with an edge protruding beyond the base body. Gluing can be used to save manufacturing costs.
  • a screw connection is used when the cover is to be releasably attached to the base body. And rolling the protruding edge into a groove on the base body is easy to do with a machine.
  • the coating is formed in sections on the cover.
  • the coating is spaced from the edge at which the cover is rolled up. This saves costs because only a smaller area of the cover is coated. In addition, it is ensured that reshaping after the coating no longer deforms the coated area and the coating is not damaged as a result.
  • the coating is formed from at least one base layer, structural layer and / or cover layer.
  • a base layer is generally required to form a defined base for the structure layer.
  • the base layer is similar rougher bumps of the base body and forms a smooth surface to which the structural layer can be applied.
  • the structure layer forms the spatial structure from spherical, irregular elevations.
  • the top layer is applied to protect the structural layer from wear.
  • a protective cover layer over the structural layer it is e.g. conceivable to form the structural layer from a softer material in order to simplify the manufacturing process.
  • the base layer, structural layer and / or cover layer are formed from different materials.
  • base layer and / or a cover layer can also be dispensed with.
  • the coating is made of chrome and / or a chrome alloy, this also has advantages.
  • the coating of such a material is particularly resistant to signs of wear.
  • the chrome and / or the chrome alloy can be easily cleaned or polished.
  • the elevations have an extent in the range from 0.1 ⁇ m to 10 ⁇ m, in particular 0.6 ⁇ m to 4 ⁇ m. With an expansion of the elevations in this size range, an effect on the sliver acts that is similar to the lotus effect known from nature.
  • the gaps between the surveys are too small for that the sliver or its fibers can get caught in between. This prevents the fibers of the sliver from being pulled through the interspaces.
  • the elevations are arranged and dimensioned such that an air cushion can form in the spaces. This air cushion can also extend beyond the elevations, so that the fiber band only comes into indirect contact with the coating by means of the air cushion.
  • a method is also proposed for producing a turntable of a spinning machine, in particular a draw frame or card, for depositing a sliver in a can, with a base body and a ribbon channel arranged in the base body.
  • a coating with a spatial structure of spherical, irregular elevations is at least partially applied to the side of the turntable facing the can when the turntable is provided. Applying the coating with a spatial structure made of spherical, irregular elevations prevents the fiber sliver or its fibers from being pulled along by the turntable.
  • the coating is arranged on a cover, the cover being fastened to the side of the base body facing the can. If the coating is arranged on the base body, this leads to cost savings through material savings and faster production. However, if the coating is applied to the cover, this leads to a simpler coating process, since only the cover is required for the coating process. The cover can then be attached to the base body in simple steps.
  • the cover can of course also be screwed to the base body. This method can be used to cover e.g. to be able to remove for maintenance purposes. This also makes it possible to replace the entire cover.
  • the cover is rolled into a groove on the base body with an edge protruding beyond the base body.
  • the coating is formed in sections on the cover.
  • the coating is formed at a distance from the edge at which the cover is rolled up. In this way, costs can be saved since only a smaller area of the cover and / or the base body is coated, and damage to the coating during the deformation 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 the base for the structural layer.
  • the base layer also serves the purpose of compensating for possible unevenness in the underlying material of the base body or the cover.
  • the base layer forms a smooth surface for the structural layer.
  • the structure layer contains the spatial structure of spherical, irregular elevations and is applied to the base layer after this. A final top coat is applied last, and is used for "sealing", or in general for protecting the structural layer from external influences.
  • the methods for applying the respective layers are as follows.
  • the base layer can 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 structure layer is applied in a closed reactor.
  • the process of galvanic chrome deposition is also used.
  • the properties of nucleation processes are exploited in this process for producing the structural layer.
  • Germ cells gradually form on the base layer and grow spherically with the duration of the process.
  • the irregular structure of the elevations is caused by the random emergence of the germ cells on the base layer.
  • the extent, distribution on the surface, growth rate or the like of the elevations can be controlled. For example, the temperature inside the reactor affects the growth rate of the bumps.
  • the structure layer can then be reproduced by setting the same physical parameters for each method. This method also achieves high dimensional accuracy.
  • a cover layer is applied by various methods, similar to that of the base layer. It should be noted here that the top layer is not applied too thickly, as otherwise the desired elevations (and the recesses in between) will be balanced with the top layer.
  • chrome plating is the wear resistance and resistance to various aggressive gases and liquids.
  • FIG 1 a schematic structure of a turntable 1 is shown.
  • the turntable 1 consists of a base body 2 and a belt channel 3 arranged in the base body 2.
  • a sliver (not shown here) is passed through the belt channel 3 and leaves the turntable 1 downwards through an opening 4 in the belt channel 3 and the base body 2.
  • a cover 5 is fastened to the base body 2 on the underside of the turntable 1 and also has the opening 4. This underside is the side facing a can when the turntable 1 is provided.
  • a coating 6 is applied, which in Figure 2 is explained in more detail.
  • FIG 2a a cross section of the coating 6 is shown with spherical, irregular elevations 11.
  • the coating 6 is applied to a base material 7.
  • the base material 7 can be part of the cover 5 or part of the base body 2.
  • 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 base material 7 and serves, for example, as a carrier layer for the structural layer 9 or compensates for unevenness in the base material 7.
  • the structural layer 9 with the spherical, irregular elevations 11 is applied to the base layer 8. As can be seen, the elevations 11 have different sizes.
  • the cover layer 10 closes the coating 6 from the outside.
  • FIG 2b is a similar cross section of the coating 6 as in Figure 2a shown. Therefore, the same components as in Figure 2a received.
  • the elevations 11 are arranged less densely on the base layer 8, ie the number of elevations 11 per unit area is less than in FIG Figure 2a .
  • Two elevations 11 can have a distance that can be in the range of several orders of magnitude of an average elevation 11. If an average elevation 11 has an extension in the range of, for example, 5 ⁇ m, then the distance between two elevations 11 can be, for example, 50 ⁇ m. However, it is also conceivable that the distance between two elevations 11 is only a fraction of the extent of one elevation 11. For example, it is also possible for the distance between two elevations 11 to be only 1-2 ⁇ m or even less.
  • FIG 3 a detail from an edge region of the turntable 1 with the cover 5 is shown.
  • a groove 12 is arranged in an edge region of the base body 2 of the turntable 1.
  • the cover 5 is fastened to the base body 2 by rolling the sides of the cover 5 into the groove 12 are.
  • the coating 6, which is shown only hinted at in comparison to the turntable 1 because of its small extent, is arranged on the cover 5. However, the coating 6 does not reach the area in which the cover 5 is rolled up. This is therefore a section in which no coating 6 is arranged.
