Definitions

  • the invention relates to an apparatus and a method for handling a metal strip.
  • the device comprises, in particular, a reeling device for winding the metal strip into a coil and a bundle driving carriage for taking over the coil from the reeling device.
  • German Offenlegungsschrift DE 10 2007 017 383 A1 discloses a means for binding a coil located on a rotary driven mandrel. Even with a coiled from thick tapes coil with strong Aufspringtendenz to allow safe and reliable encasement, the document discloses that at least one pressure roller is provided by means of which pre-bent flat steel strip is passed around the coil to secure the coil against cracking.
  • the European patent EP 1 888 284 B1 discloses an apparatus and method for taking a sample from a metal strip wound into a coil.
  • the device according to the invention provides two floor rolls for supporting a coil. At least one of the floor rolls is designed to be rotationally driven. The band end must always be fixed by one of the rollers, in particular for high-strength or thick bands, in order to avoid unwanted popping of the collar.
  • at least one pressure roller is provided, which touches the coil on its lateral surface and fixed with respect to its position.
  • One of the two bottom rollers is designed to be lowered and can be pivoted away from the coil after fixing the coil by the remaining bottom roller and the at least one pressure roller. By pivoting away the one bottom roller remains an increased free tape length between the remaining bottom roller and the pressure roller, whereby the local deformation tape end is lower without the risk of a springing of the coil threatens.
  • the publication JP 07025525 A describes a device for handling a metal strip with a reel device for winding a metal strip to a coil on a coiler mandrel, and a Bundausfahrwagen with supports for receiving the coil.
  • a hold-down arm which is made obliquely against the coil, a hold-down force is applied to the outer circumference of the coil, so as to press the coil against the supports of the Bundausfahrwagens and to secure against popping.
  • the publication JP 2007 044747 A shows a metal coil on a Bundausfahrwagen and a hold-down arm, which is arranged in the eye of the coil for applying a pressing force.
  • a handling device for a metal coil is known, with a Bundausfahrwagen for receiving the coil.
  • a hold-down arm is arranged to exert a hold-down force on the outer circumference of the coil.
  • the finished coils are conveyed out of the reel device at the end of the winding process with a coil conveyor.
  • a coil conveyor To drive the Bundausfahrwagen under the coil, if this in the reel is wound up on the coiler mandrel.
  • the typically two supports of Bundausfahrwagens are then raised and employed from below against the coil on the coiler mandrel so that the coil then rests on the two supports, after the coiler mandrel despread and / or was withdrawn from the eye of the coil.
  • the Bundausfahrwagen initially has the task to secure the end of the metal strip by the coil is rotated on the two supports so that the tape end is pressed by the weight of the coil against the supports. After such a filing of the coil on the Bundaus-trolley, the coil is spent using the federal contract carriage to a coil binding device.
  • a trend in conventional hot strip is in the production of metal strips with particularly high strength and strip thickness. These are used to make tube steels and wear surfaces with extreme strength. When these materials are wound up, a residual stress remains in the coil, which tends to reopen the end of the metal strip. This tendency increases with greater strength and greater tape thickness, and is particularly noticeable in small, light weight and small diameter coils. Typical small collar diameters are 1000 mm to 2300 mm.
  • the coil weight is often not sufficient to secure the end of the metal strip or the coil on the two supports of Bundausfahrwagens. Rather, there is the danger that the coil can not be safely pulled from the coiler mandrel and spent to Abbindestation. The coil can get caught on the coiler mandrel, lift itself from the Bundausfahrwagen or jump up.
  • the present invention seeks to further develop a device and a method for handling a metal strip to the effect that the handling of the metal strip, in particular a metal strip with high residual stress in the transfer From the coiler mandrel on the Bundausfahrwagen and during transport with the Bundausfahrwagen additionally secured against cracking.

  • This is characterized by a second hold-down arm for exerting a second hold-down force F2 with its coil-side end in the eye of the coil for pressing the coil onto the supports of the cuff carriage.
  • the first hold-down arm is designed to set on the circumference of the coil such that the first hold-down force F1 exerted on the coil has at least one component in the direction of the weight force.
  • the second hold-down arm is preferably designed to be positioned in the eye of the coil in such a way that the second hold-down force F2 exerted by it has at least one component in the direction of the weight force.
  • a force is exerted with at least one component in the direction of the weight force in the eye of the coil, whereby the coil is advantageously prevented from popping up.
  • the invention can be used for coils without internal residual stress, with a small residual stress or even with a high residual stress.
  • the first hold-down arm would indeed be dispensable; However, it is harmless if this is still provided according to the present invention in these cases anyway.
  • the hold-down arm may be configured to exert an active pressing force on the outer circumference of the coil.
  • the hold-down can also be powerless but fixed in its height attached to the outer circumference of the coil.
  • the active pressure force equivalent to the hold-down force, exceptionally amount equal to zero.
  • a (counter) force can arise in this case when the coil tries to jump up, but is prevented from popping up by the first hold-down arm, which is firmly positioned in its height.
