Definitions

  • the invention relates to a method and a reel system for reeling a metallic strip, the strip being coiled in a reel stand on a reel mandrel to form a coil.
  • Metallic strips such as steel strips are usually coiled into so-called coils for transport and storage. Restoring forces act in the coiled strip, which can lead to uncoiling, that is, to the coil opening.
  • Various methods and devices are known for reeling a tape into a coil and securing it against uncoiling.
  • EP 2 648 860 B1 discloses an apparatus and a method for handling a metal strip, wherein a coil is pulled off a stationary coiler mandrel with the aid of a collar extension carriage and is thereby secured against popping open by a first hold-down arm and by a second hold-down arm which engages in the coil eye of the coil.
  • EP 2 644 290 A1 discloses a reel method and a reel system for a strip, the strip being coiled in a reel device about a coil axis to form a coil with a number of turns lying radially one above the other.
  • the coil is still secured in the reel device by unfastening the radially outermost turn by means of a securing device relative to at least one turn located further inside.
  • the coil, which is secured against uncoiling, is removed from the reel device together with the securing device by means of a conveying device.
  • US 3,527,425 A discloses a tensioning reel with an expandable reel mandrel for reeling a metallic band to a coil.
  • the reel mandrel can be moved in the axial direction along a telescopic drive shaft by means of a slide on rails in order to pull the reel mandrel away from the coil, the actual drive remaining spatially fixed.
  • the invention has for its object to provide a method and a reel system for reeling a metallic strip into a coil, which are improved in particular with regard to securing the coil against uncoiling.
  • the object is achieved by a method with the features of claim 1 and a reel system with the features of claim 8.
  • the strip is coiled in a reel stand onto a reel mandrel to form a coil with a coil eye through which the reel mandrel runs and is pressed against the reel mandrel by at least one pressing element during the reeling.
  • the coiler mandrel is at least partially moved out of the coil eye of the coil along a longitudinal axis of the coiler mandrel, the coil being held in position by the at least one pressing element and secured against uncoiling.
  • the coil is secured against uncoiling by a securing device, and the coil secured against uncoiling by the securing device is released by the at least one pressing element and transported away from the reel stand.
  • the invention thus provides a movable reel mandrel which is completely or partially moved out of the coil eye of the coil after the reel has been reeled. So it becomes, for example, different from that EP 2 648 860 B1 known prior art, not the coil is pulled from the coiler mandrel, but the coiler mandrel is pulled out of the coil.
  • the coil is temporarily held by at least one pressing element, which is also used for reeling the strip, and is secured against uncoiling.
  • the coil is then secured against uncoiling by a safety device. In this way, the coil is secured against uncoiling after coiling and during removal.
  • One embodiment of the invention provides that the securing device exerts a securing force directed radially outward from the coil eye onto the coil.
  • the securing device according to this embodiment of the invention acts on the coil from the coil eye and exerts a radially outward securing force on the coil.
  • This embodiment of the invention takes advantage of the fact that the coil eye is free after the reel mandrel has been pulled out and the securing device can therefore engage the coil from the coil eye. Securing the coil against uncoiling from the coil eye saves space compared to a fuse that ripens on an outer circumference of the coil, since no components of the securing device have to be positioned on the outside of the coil.
  • a further embodiment of the invention provides that the coil is transported out of the reel stand on an extension carriage.
  • the coil is stored on at least one support of the extension cart during removal from the reel stand and is pressed against the at least one support by the securing device. This enables the coil to be secured against uncoiling when the coil is transported away on an extension cart.
  • each pressure element is designed as a pressure roller which is placed against the coil in order to hold the coil and to prevent it from being unwound.
  • Pressure rollers are particularly suitable pressure elements since they can also advantageously support the winding of the strip, in particular if they are designed to be rotatable about their longitudinal axes.
  • a further embodiment of the invention provides that the reel mandrel has a variable diameter in a plane perpendicular to its longitudinal axis and the diameter of the reel mandrel is reduced before and when the reel mandrel is moved out of the coil eye.
  • the reduction in the diameter of the reel mandrel advantageously simplifies the removal of the reel mandrel from the coil eye of the coil, since it avoids or at least reduces friction between the reel mandrel and the coil during the removal of the reel mandrel from the coil eye.
  • a further embodiment of the invention provides that the reel mandrel is rotated about its longitudinal axis by a motor via a gear during reeling and that the motor and the gear are moved together with the reel mandrel when the reel mandrel is moved out of the coil eye.
  • the common movement of the reel mandrel, the motor and the gearbox enables the transmission of higher torques compared to a fixed arrangement of the motor and the gearbox, since no telescopic drive shaft has to be provided in order to drive the reel mandrel. This makes it possible, in particular, to reel strips that are made from higher-strength materials and / or to produce coils with higher coil weights.
  • a reel system according to the invention for carrying out the method according to the invention comprises a reel stand in which the strip can be reeled to the coil, a reel mandrel which is between a first end position in which it is moved into the reel stand and a second end position, in which it has at least partially moved out of the reel stand, can be moved along its longitudinal axis, at least one pressing element which can be pressed against the coil in the reel stand, in order to press the strip onto the reel mandrel during reeling and the coil in its after reeling Hold position and secure against uncoiling, and a safety device through which the coil can be secured against uncoiling while the coil is being transported out of the reel stand.
  • a reel system according to the invention enables the method according to the invention to be carried out.
  • the advantages of a reel system according to the invention therefore correspond to the advantages of the method according to the invention already mentioned above and are not mentioned again separately here.
  • An embodiment of the reel system according to the invention provides that the securing device has a hold-down arm which can be moved into the coil eye and with which a securing force directed radially outward from the coil eye can be exerted on the coil.
  • This configuration of the reel system enables the above-mentioned space-saving securing of the coil from the coil eye.
  • the securing device can have an adjusting arm which can be adjusted against an outer surface of the coil and with which a securing force directed towards the coil eye can be exerted on the coil.
  • This embodiment of the reel system according to the invention can be advantageous, for example, if a hold-down arm that can be retracted into the coil eye is not sufficient to secure the coil or the reel system already has a positioning arm that can be adjusted to an outer surface of the coil and that can be used to secure the coil.
  • a further embodiment of the reel system according to the invention provides an extension carriage for removing the coil from the Reel stand in front.
  • the securing device can be arranged on the exit carriage. The arrangement of the securing device on the extension carriage enables a particularly space-saving and efficient execution of the securing device, since no separate moving device has to be provided for the securing device.
  • a further embodiment of the reel system according to the invention provides a motor and a transmission with which the reel mandrel can be rotated about its longitudinal axis and which can be moved together with the reel mandrel.
  • a further embodiment of the coiler system according to the invention provides that the coiler mandrel can be expanded in a plane perpendicular to its longitudinal axis and the coiler system has a spreading device with which the coiler mandrel can be expanded. In particular, the spreading device can be moved together with the coiler mandrel.

  • the reel mandrel 7 can be rotated by a motor 21 about its longitudinal axis 15 via a gear 19. Furthermore, the reel mandrel 7 can be expanded in a plane perpendicular to its longitudinal axis 15 by a spreading device 23. By spreading the coiler mandrel 7, the diameter of the coiler mandrel 7 is increased.
