Definitions

  • the invention relates to a pressing and separating device for a metal strip to be connected to a take-up reel, in particular a reversing reel a pressing means and a knife arranged downstream of it in the tape running direction.
  • connection of a tape during ongoing transport exists both at the start of winding when working with a lost beginning of the tape and during winding, when winding from one take-up reel to the other take-up reel to be changed.
  • the invention has for its object to provide a pressing and separating device of the type mentioned, which ensures continuous cutting of the tape without damaging the tape during continuous transport of the tape.
  • This object is achieved in that the knife can be pressed against the reel and folded away in the direction of tape travel.
  • a brush known per se is particularly suitable as a pressing means.
  • the knife Before the pressing and separating process, the knife should preferably be held by spring means in a position which is preferably oriented transversely to the tape running direction.
  • the attachment means can be an adhesive coating.
  • the device according to the invention it is possible to disconnect and connect the tape at high tape speeds of approx. 40 m / sec without problems.
  • the running belt is pressed onto the winding mandrel by means of the brush, and in the process the Ribbon cut. Because the knife can be folded away, the belt is not damaged, rather the knife is taken along by the belt in the direction of the belt.
  • the band casting device consists of a container 1 filled with molten metal, a delivery or riser pipe 2 immersed therein, a pouring nozzle 3 and a moving heat sink in the form of a cooled casting wheel 4.
  • Band casting devices in this or a similar embodiment are known. So that due to the centrifugal force acting on the belt 6, the belt 6 does not detach too soon from the jacket of the casting wheel 4, a guide 5, which is equipped with blowing nozzles on the belt, extends over the casting wheel 4 and is arranged concentrically to the jacket of the casting wheel 4 6 blow and thereby press it against the jacket of the casting wheel 4.
  • Belt casting can also be used, for example, for casting devices with two casting wheels or Realize pouring devices with nozzles for multi-layer pouring. (See German patent applications P 35 21 778.2 and P 36 02 594.1). It is only important that the strip 6 has solidified at the detachment point of the belt 6 from the casting wheel 4. Sufficient tensile strength to apply a tape tension is not yet necessary here.
  • a wedge-shaped detaching member 7 is arranged in the gusset between the jacket of the casting wheel 4 and the belt 6, which can be equipped with blowing nozzles to support the detachment.
  • This detaching element 7 is followed by a brush roller 8 with friction rollers at its ends, which run on the jacket of a first cooling wheel 9.
  • the brush roller 8 presses the belt 6 against the jacket of the cooling wheel 9, so that, above all, the beginning of the belt easily runs into the entrance of a guide channel which is formed by the jacket of the cooling wheel 9 and a guide wall 10 arranged concentrically therewith.
  • the first cooling wheel 9 is followed by a second cooling wheel 11 with a correspondingly arranged guide wall 12.
  • the belt 6 is guided in an S-shape over the casting wheel 4 and the two cooling wheels 9, 11.
  • the guide walls 10, 12 on the cooling wheels 9, 11 are equipped with blowing nozzles that blow a cooling medium against the band 6, so that the band 6 is pressed firmly against the shells of the cooling wheels 9, 11 for the purpose of intensive contact cooling.
  • a cooled medium in particular air or an inert gas, is preferably used as the blowing medium. This applies above all to the blowing medium of the nozzles on casting wheel 4.
  • a brush roller 13 is arranged as an additional guide, which is driven by a friction wheel running on the jacket of the cooling wheel 11.
  • a flat guide channel 14 adjoins the guide channel 11, 12.
  • the width of this guide channel 14 perpendicular to the band plane is smaller than the bandwidth.
  • the guide channel 14 can consist of a U-profile, which can be closed by a side cover. By opening the cover and by lateral adjustment, it is possible to release the band 6 guided through the channel 14.
  • the strip thickness can be measured with an uninterrupted conveying of the strip 6 with a measuring device 17 which is only indicated.
  • a suction device 15 only indicated in the drawing, is connected, which allows a gas flow to flow through the channel from top to bottom.
  • a pair of pinch rollers 16 is provided at the lower exit of the guide channel 14.
  • the band 6, By clamping the band 6, it is fixed laterally. From this moment on, the guide channel 14 is therefore no longer required, but can be opened and moved out of the guide area.
  • a scanning device not shown, the position of the tape 6 can then be detected and used for the winding process to be described.
  • each take-up reel 19, 20 is one Band guide roller 22, 23 assigned at a lateral distance, which guides the tape when changing the reel.
  • the winding mandrel of each take-up reel 19, 20 has a tacking agent acting on the tape, for example an adhesive coating.
  • a pressing and separating device 24 is arranged, which, as can be seen in FIGS . With this pressing and separating device 24, the belt 6 running at high speed can be connected to the take-up reel 19 located in position.
  • a respective pivotable pressure roller 27 is assigned to the take-up reel 19 or 20 which is in the change position.
  • the molten metal applied to the casting wheel 4 is introduced into the first section of a guide channel formed by cooling wheels 9, 11 and guide walls 10, 12 with the aid of the detaching member 7 and the brush roller 8.
  • the belt 6 has a very low strength when leaving the casting wheel 4, but then receives such a strong cooling from the cooling wheels 9, 11 that it is sufficiently firm when leaving the first section of the guide channel to be guided freely. It then passes through the vertically arranged guide channel 14, from which it enters the scrap collecting container 18. This operating phase is shown in Figure 1.
  • the pinch rollers 16 of the safety gear are turned on.
  • the driven pinch rollers 16 take over the leadership of the belt 6 and keep it taut.
  • the tape guide channel 14 can then be removed.
  • the position of the band is detected by means of the scanning device, not shown in the drawing, for the position of the band 6.
  • the tape 6 and the take-up reel 19 are aligned with one another, for example by moving the take-up reel 19 axially with the tape guide unchanged.
  • the pair of pinch rollers 16 is then adjusted in the direction of the take-up reel 19 and the pressing and separating device 24 is moved against the tape 6 in order to attach the tape to the adhesive coating of the mandrel of the take-up reel 19.
  • the brush 25 presses the running belt in a wiping motion.
  • the collapsible, spring-mounted knife 26 is folded away by the running belt 6 and therefore does not hinder the movement of the belt either.
  • the pair of pinch rollers 16 and the pressing and separating device 24 are returned to their rest position.
  • the tape 6 is wound on the reel 19 until the reel 19 is full.
  • the turning reel 21 is pivoted so that the empty take-up reel 20 comes into the position of the full take-up reel 19.
  • the conveying of the belt need not be interrupted during this turning process.
  • the still wound on the take-up reel 19 is guided after the pivoting process over the guide roller 23, which ensures that the tape 6 is guided substantially vertically past the empty reel 20 for connection to the mandrel.
  • This operating phase is shown in dashed lines in FIG. 1.
  • the pressing and separating device 24 is actuated again.
  • the pivotable pressure roller 27 pressed onto the roll winder 28 so that the bundle 28 remains tightly wound after the tape is cut.
  • the winding 28 can be pulled off the mandrel of the take-up reel 19 and fitted with a new winding tube.
