Definitions

  • Such a winding layer is generally known. Exemplary reference is made to EP 0 679 453 A1.
  • the winding layer rotates around the shaft axis.
  • the winding layer is along the shaft axis the rod-shaped rolling stock is fed at the rolling stock speed.
  • the rolling stock runs into the inlet end of the laying tube and emerges tangentially from the outlet end so that it is in shape a series of rings or turns on a conveyor belt can be filed.
  • the peripheral speed of the outlet end which are proportional to the speed and radial distance the outlet end of the shaft axis corresponds approximately the rolling stock speed.
  • the winding layer experiences in the rest state with horizontally running A deflection due to gravity. This deflection essentially determines the resonance frequency.
  • the resonance frequency limits the speed and thus indirectly also the maximum possible rolling stock speed. The lower the gravity-related, the higher the resonance frequency Deflection of the laying tube holder in the idle state is.
  • the object of the present invention is a Winding layer to evolve in such a way that it is as possible low deflection due to gravity and thus a has the largest possible resonance frequency.
  • the object is achieved in that the laying tube holder at least partially made of a material that is less Has density than steel.
  • plastics especially fiber-reinforced Plastics, in question.
  • the laying tube holder usually has a connector for non-rotatable connection with the hollow shaft, a substantially rotationally symmetrical center piece, one arranged on the center piece Support structure for the laying pipe and a compensation structure to compensate for unbalance. At least that Support structure should consist of the material that is a lesser Has density than steel.
  • the laying tube can also be made of a material that is one has lower density than steel. The same applies to one guide extension subordinate to the laying tube. Come here due to the thermal stress on these parts in particular ceramic materials, possibly also composite materials Light metal and ceramic, in question.
  • the laying tube can e.g. B. consist of a light metal and one on the inside Have ceramic layer.
  • a rod-shaped rolling stock 1 is by means of a Winding layer 2 in the form of a series of rings or turns 3 stored on a conveyor belt 4.
  • the Rolling stock 1 the winding layer 2 at a rolling stock speed vW fed.
  • the winding layer 2 rotates at the same time at a speed n about a shaft axis 5.
  • the winding layer 2 is in a known manner by means of a motor 6 a gear 7, usually a reversing gear 7, driven.
  • the winding layer 2 has a hollow shaft 8, one Laying tube holder 9 and 10 laying tube.
  • the hollow shaft 8 is stored in a sub-warehouse 11 and a main warehouse 12 in this way is that the hollow shaft 8 is rotatable about the shaft axis 5 is.
  • the sub bearing 11 and the main bearing 12 are axially distanced.
  • the laying tube holder 9 projects beyond the main bearing 12. He has a connector 13, z. B. a connecting flange 13, and an essentially rotationally symmetrical center piece 14 on. By means of the connector 13, the laying tube holder 9 rotatably connected to the hollow shaft 8. With the middle piece 14 are a support plate 15, support plates 16, 17 and a compensating structure 18 connected.
  • the support plate 15 rotates with the laying tube 10. It has connection eyes 19 on which holding elements 20 are attached. By means of the holding elements 20 carries the support plate 15 and thus also the laying tube holder 9 the laying tube 10.
  • the support plates 16, 17 support the support plate 15 axially forwards and backwards from.
  • the support plate 15, the support plates 16, 17 and the holding elements 20 together form one arranged on the center piece 14 Support structure for the laying pipe 10.
  • the compensation structure 18 is used to compensate for the structure and the laying pipe 10 caused unbalance.
  • the laying tube 10 has an inlet end 21 and an outlet end 22 on. Describes between the inlet end 21 and the outlet end 22 the laying tube 10 is a three-dimensionally curved guideway for the rolling stock 1.
  • the inlet end 21 is aligned the shaft axis 5.
  • the outlet end 22 has from the shaft axis 5 a radial distance d.
  • the rolling stock 1 runs the shaft axis 5 along, enters the laying pipe 10 at the inlet end 21 in and at the outlet end 22 out of the laying tube 10.
  • the outlet end runs 22 with a peripheral speed vU around the shaft axis 5 um.
  • the peripheral speed vU corresponds to the Roll speed vW.
  • the outlet end 22 thus describes a circle 23 around the shaft axis 5.
  • the laying tube 10 is a Subordinate extension 24.
  • the guide extension 24 serves in particular to properly place the last one Turns 3 on the conveyor belt 4.
  • the winding layer 2 points in the horizontal direction Shaft axis 5 of the winding layer 2 according to FIG. 3 a deflection D due to gravity.
  • the gravity-related Deflection D is clear in Figure 3 half exaggerated.
  • the gravity-related Deflection D determines the resonance frequency that the coil layer 2 has in operation.
  • the resonance frequency is limited the speed n and thus indirectly the maximum possible rolling stock speed vW.
  • the resonance frequency is the higher the lower the deflection caused by gravity D of the winding layer 2 is.
  • the laying tube holder 9 is at least partially made of one material, which has a lower density than steel.
  • materials come especially light metals, e.g. B. aluminum and magnesium, in question. Possibly. can also be a fiber reinforced Plastic are used. This can be achieved that the gravity-induced deflection D of the winding layer 2 by more than half compared to gravity Deflection D 'of a structurally identical coil layer made of steel.
  • At least those that are not subjected to bending should Parts of the laying tube holder 9 are made of light metal become. At least the supporting structure should be made of light metal consist.
  • the laying tube 10 and a guide extension that may be arranged after this 24 can be at least partially made of one material exists, which has a lower density than steel. At these parts come due to the thermal stress in particular ceramic materials, possibly also composite materials made of light metal and ceramic, in question.
  • the laying pipe 10 can e.g. B. consist of a light metal and on it Have a ceramic layer on the inside.
  • the deflection caused by gravity is essentially of the bending line inclination of the hollow shaft at the main bearing. Therefore, if necessary, the middle piece 14, possibly even the connecting piece 13, made of light metal.
  • only the hollow shaft 8 consists Steel.
  • the support plate 15, the support plates 16, 17, the compensating structure 18, the center piece 14 and even the connector 13 are made of light metal.
  • the laying pipe 10 is made of light metal and has an inside Ceramic layer on.
  • the guide extension 24 consists in his thermally and mechanically stressed part made of ceramic and otherwise made of light metal.
