Definitions

  • the invention relates to a device for winding strip-shaped rolling stock onto the mandrel of a reel, in which the first windings are held by means of a toothed chain which partially wraps around the windings and is endlessly guided over deflection wheels, the deflection wheels being provided with circumferential toothing corresponding to the toothed chain and at least one Part of the deflection wheels is driven.
  • Belt winders are known for the winding of cold strip, in which a belt running endlessly around deflection rollers partially wraps around the winding mandrel and thus the windings resting on it.
  • the belt has no drive and is carried by the mandrel by frictional contact.
  • Belts and pulleys are arranged on swivel-away frame parts which can be swiveled in for winding and swung away after the unwinding process.
  • metal cord belts are preferably used, these are rubber or rubber belts with a particularly abrasion-resistant surface, which are reinforced on the inside with highly elastic steel cables.
  • Such belts can be used up to temperatures of 200 degrees C and for low winding speeds of approx. 1.5 m / sec.
  • a belt winder for a cold strip reel which, in the manner of a caterpillar chain, has pressure bodies rotatably mounted on at least one toothed chain and extending transversely to the toothed chain.
  • the pressure hulls are covered with an elastic material.
  • the well-known belt sling is unsuitable for hot strip because the pressure pieces cannot withstand high temperatures and do not allow scale to be removed.
  • the known device is therefore only suitable for cold strip.
  • wire link strips made of round or flat wire, which are made of chrome-nickel steels. These link belts wear out very quickly due to the high mechanical load on the deflections, especially at high speeds, with winding speeds of approximately 0.5 m / sec. represent the upper limit.
  • the temperature load of such wire link belts should not exceed 400 degrees Celsius.
  • wire link belts used in hot coiler systems are their contamination by the scale that is produced. This requires extensive maintenance of the link belts if the service life specified above is to be achieved.
  • the wire link belts are also sensitive when belts with different widths have to be rolled; because they are not suitable for absorbing lateral forces.
  • the belt width should preferably be larger than the belt width, which, however, requires frequent changing of the belts when rolling belts of different widths.
  • the jerky acceleration on contact with the mandrel is also disadvantageous for the service life of the wire link belts.
  • the toothed chain consists of a loosened tab linkage with a plurality of chain parts which are arranged next to one another and are kept at a distance by spacers, which one form a common strand, the chain links being smooth on the side facing the band to be wound and toothed on the side facing the deflection wheels.
  • Such a tooth chain for example made of heat-treated chain steel, is highly heat-resistant and wear-resistant.
  • the smooth side of the toothed chain protects the belt surface, whereby a speed synchronous with the incoming belt or the mandrel can be set by the drive of the deflection wheels. This reliably prevents relative movements between the tooth chain and the belt surface that could lead to wear.
  • the back of the tooth chain i.e. the side facing the band to be wound is almost rigid, but can be bent well over the large mandrel diameter of the coiler mandrel. In the opposite direction, the toothed chain is easy to turn, so that it can be guided over the toothed deflection wheels.
  • the proposed tooth chain is for speeds up to 6 m / sec.
  • Cyclic oil spray lubrication can be used to lubricate the chain links and at the same time cool the chain links.
  • Such a linkage assembly consisting of a plurality of chain parts arranged side by side can be used for different strip widths, so that an exchange when winding different strip widths is not necessary.
  • the tooth chain according to the invention significantly increases the life of the winding device, namely to approximately 2 years.
  • 1 denotes the carousel reel, which has two reel mandrels 2 offset by 180 degrees, of which only one is shown.
  • the belt 5 inserted by the driving roller set 3 through the threading device 4 is transported into the region of the reel mandrel 2 and is passed there between the reel mandrel and the toothed chain 6 partially wrapping around the reel mandrel 2.
  • the toothed chain 6 is guided around toothed deflection wheels 7a to 7d, of which the deflection wheel 7e is driven.
  • the deflection wheels 7a to 7c are arranged on a common lever 8 which can be pivoted away by pressure medium 9.
  • the deflection wheel 7e remains stationary.
  • the toothed chain 6 is shown in detail in the side view, it recognizably consists of the chain links 10, which is connected via links 11, which are bolted to the chain links 10 at 12.
  • the chain links 10 are smooth on one side of the toothed chain 6 and with the tabs 11 designed flush, while on the opposite side the chain links 10 are toothed at 13. With these toothings 13, the toothed chain engages in the corresponding circumferentially toothed deflection wheels 7a to 7e, as will be described later.
  • FIG. 3 shows a top view of a link plate assembly of a toothed chain according to the invention, the link plates 11 being recognizably arranged centrally between two chain links 10 and being kept at a distance by spacers 14 on the bolt 12.
  • FIG. 4 shows a section through the toothed chain 6 according to the invention in the area of the deflection wheels 7e. These are held on the common shaft 15 at 16 so that they cannot rotate and are driven by the bevel gear 17 by a bevel gear 18 which is connected to a geared motor 19.
  • the deflection wheels 7e are provided with a circumferential groove 20 and are also toothed at 21 on their circumference. While the teeth 13 of the chain 6 engage in the toothing 21, the tabs 11 are guided in the groove 20 of each deflection wheel 10e, so that a lateral displacement of the toothed chain 6 is prevented.
  • the entrainment takes place via the teeth 21 of the deflection wheels 10e and the teeth 13 of the chain 6 at a speed which corresponds to the running-in speed of the band or the winding-up speed of the mandrel.
  • the tape is shown at 5 in FIG. 4; the toothed chain can be seen to consist of 4 adjacent chain units lying on the belt 5, each chain unit being designed according to FIG. 3.
