Definitions

  • the invention relates to an inductor core for an inductively heated godet and an inductor and an inductively heated godet.
  • the inductor core comprises a plurality of star-shaped radially arranged Induktorkernlamellen with radial sections and in each case an outer and an inner axial section.
  • a sleeve is disposed around the inductor core laminations with the outer axial portions of the inductor core laminations adjacent the sleeve.
  • godets are used on spinning machines or on machines for producing fibers, for example yarns, as guide and take-off rolls for the fibers to be processed.
  • Inductively heated godets are known in the art. Such godets have a magnetic inductor core, which is wound with coil windings, wherein the coil windings can be acted upon by an electrical alternating current.
  • the inductor core causes bundling and amplification of the magnetic field generated by the current-carrying coil windings.
  • electrical eddy currents are induced in electrically conductive parts of the galette, which heat the electrically conductive parts and thus the galette.
  • gray iron inductor cores made of gray cast iron. Although gray iron inductor cores can be produced inexpensively, even at low magnetic field strengths, ie at approximately 1100 VA, the inductor cores become magnetically saturated, which impedes penetration of the magnetic field generated by the electrical current flowing in the coil windings into the inductor core. High heating capacities that make it possible to heat the surfaces of the godet in contact with the fibers to be processed to a temperature of 240 ° C. and above, which is necessary for various processing methods of fibers, are therefore difficult to achieve with gray iron inductor cores. In addition, electrical eddy currents are also induced in such inductor cores. This leads to a heating of the inductor core itself, which makes a rapid control of the galette temperature difficult.
  • inductors with laminated inductor cores are known.
  • inductor core laminations having radial sections and each having an outer and an inner axial section are arranged around an inner tube such that the inductor core laminations each adjoin the outer surface of the inner tube with their inner axial section.
  • the Induktorkernlamellen are welded to the inner axial portion of each of the outer surface of the inner tube.
  • the Induktorkernlamellen are made of transformer sheet.
  • the inductor core is wound with coil windings. When wrapping care must be taken that insulation of the wire from which the coil windings are constructed is not damaged.
  • Laminated inductor cores prevent, according to a laminated Transformer core, the formation of eddy currents in the inductor core. If the sleeve is made of an electrically conductive material, eg of steel, eddy currents are induced in the sleeve which lead to a heating of the sleeve and thus of the godet, into which the inductor core is inserted. The inductor core itself does not heat up significantly by laminating the inductor core. Local heating is achieved close to the surface of the galette. Laminated inductor cores have significantly higher magnetic saturation limits than gray iron inductor cores due to the material used to make the fins, which allows much higher magnetic fields to be generated by the inductors.
  • a disadvantage of the known laminated inductor cores is that the Induktorkernlamellen must be individually welded to the inner tube. Furthermore, it is complicated to arrange the inductor core lamellae in a star shape, ie spaced apart from one another at the outer diameter.
  • the sheets from which the Induktorkernlamellen are made they are provided at their outer areas with a nose as a spacer. When assembling the Induktorkerns the sheets are then arranged individually. For better fixation, the sheets can be fixed to a sleeve with a weld seam, whereby disadvantageous eddy currents occur during operation of a galette equipped with such an inductor core.
  • the pamphlets DE 19 57 110 A1 and CH 467 363 A each disclose a heatable Gallette with an inductor core, which comprises a plurality of star-shaped radially arranged Induktorkernlamellen, wherein formed as locking fixation means are provided.
  • the latches are formed circumferentially on Abschlußdorfer so that the Induktorkernlamellen are secured against slipping in the radial direction.
  • the invention has for its object to provide an inductor core and an inductor for an inductively heated godet and an inductively heated godet, which avoid the disadvantages of the prior art and in particular are easy to manufacture and allow high heat output.
  • the task with respect to the inductor core is achieved by an inductor core for a heatable godet with a plurality of star-shaped radially arranged inductor core lamellae with radial sections and in each case one outer and one inner axial section.
  • the inductor core has fixing means designed as latches, wherein the fixing means are arranged to fix the inductor core lamellae at their radial sections to termination plates each having a surface complementary to the radial sections.
  • the inductor core laminations are arranged between the finalists.
  • the locking means formed as locking means are formed as radially outwardly extending arranged on the Abschlußstellern and at the radial sections of tongue and groove locks.
  • the latches are designed according to tongue and groove connections, wherein preferably the radial sections of the inductor core lamellae are inserted as a spring into mating complementary grooves in the termination plates, that is to say latched. This is a particularly easy to manufacture embodiment of the fixative.
  • the fixing means may be arranged to lock the Induktorkernlamellen with their inner axial sections on an outer surface of an inner tube with the inner tube.
  • the inductor core therefore has termination plates each with a surface that is complementary to the radial sections.
  • the Induktorkernlamellen are arranged between the Abschlußstellern and the fixing means are adapted to fix the Induktorkernlamellen at the radial portions of the Abschlußstellern.
  • the complementary surfaces of the terminator points in the direction of the radial sections of the Induktorkernlamellen.
  • the surfaces have a shape that shapes the radial sections. In the simplest case, the radial sections and / or the axial sections are straight edges of, preferably punched, sheets.
  • impressions on the surfaces of the end plates are designed as grooves that extend radially outward from a center point of the respective plate and into which in each case a radial section of the inductor core lamellae can be inserted. This leads to a positional fixation of the inductor core laminations relative to the termination plates.
  • the Induktorkernlamellen be through easy assembly and / or mating fixed to the end plates or the inner tube.
  • a laminated inductor core is provided which combines the advantages of known laminated inductor cores with a simple and inexpensive manufacturability. With the inductor core according to the invention heating powers of 1000 watts and more can be achieved, whereby the coming into contact with the fibers in contact surfaces of a galette can be heated above 240 ° C. It is a precise heating with rapid temperature changes possible. Furthermore, a change in the inductor core length is very easily possible by varying the length of the inductor core lamellae, without incurring additional expense during assembly of the inductor core.
  • the inductor core lamellae are formed as cuboidal packets of sheets, preferably with integrally formed spacers.
  • cuboidal laminations can be produced very cheaply from punched sheet metal parts.
  • the arrangement of a plurality of cuboid laminated cores facilitates the assembly of the inductor core according to the invention over an embodiment with many individual sheets as Induktorkernlamellen, wherein the magnetic properties may have the same values.
  • the spacers prevent that the sheets can be electrically conductively connected over a large area, whereby the formation of eddy currents is further complicated.
  • a regular distance between the sheets is achieved, creating a symmetrical magnetic field and thus a uniform heating of the godet can be achieved.
  • the sheets are preferably formed as stampings. This allows a simple and rapid production of Induktorkernlamellen.
  • the Induktorkernlamellen can preferably be made of transformer sheet, for example punched.
  • the catches particularly preferably each comprise a peripheral groove in the end plates and complementary elevations on the radial sections and radial grooves complementary to the radial sections in the end plates.
  • This embodiment of the latches is particularly suitable for the positional fixing of inductor core lamellae designed as a package of sheets. The packets are thereby prevented by the circumferential groove from slipping in the radial direction and by the radial groove from slipping and / or twisting perpendicular to the radial direction.
  • the Induktorkernlamellen on their outer axial sections led out radial section extensions of the radial sections.
  • This shape of the inductor core lamellae enables effective removal of the magnetic field from the region of the inductor core into electrically conductive parts of the godet. These parts can be heated up very quickly and effectively.
  • a position fixation of a sleeve provided with coil windings on the Induktorkernlamellen may result.
  • the terminators are preferably screwed together with axially extending, preferably in intermediate spaces between the Induktorkernlamellen, screws. Such screwing allows a stable fixation of the inductor core lamellae in the axial direction of the inductor core.
  • the terminators and the inductor core lamellae are held together axially.
  • the screws themselves additionally amplify a generated magnetic field when passed between the inductor core laminations.
  • the terminators are preferably made of non-magnetic material, e.g. made of aluminum. A field gain in the axial direction out of the region of the inductor core is thereby avoided.
  • An inductor according to the invention comprises, in addition to an inductor core according to the invention, coil windings, wherein the coil windings are wound onto the inductor core.
  • the coil windings can also be wound onto a sleeve enclosing the inductor core.
  • the bobbin i. the coil windings on the sleeve, can then be prefabricated.
