Definitions

  • the invention relates to a method for winding a metallic strip according to the preamble of claim 1 or claim 3, and a corresponding device according to the preamble of claim 11.
  • reel devices In order to prepare for the transport of steel strips, reel devices are known in the prior art, in which a respective band is guided from a driver device to a reel mandrel rotatably mounted about an axis and is then wound onto the reel mandrel. Between the driver device and the reel mandrel there is a guide shaft through which the tape to be wound is traversed. A belt switch is arranged adjacent to an opening in the guide shaft, with which the belt experiences a change in direction and is thus guided into the guide shaft.
  • the head of a tape to be wound hits the tape switch or other components that, viewed in the transport direction of the tape, after or after passing the driver device with a relatively high impulse, due to the speed and rigidity of the tape are arranged downstream of the belt switch.
  • the mechanical guiding or diversion of the belt which takes place essentially through contact with the belt switch, disadvantageously leads to a frictional resistance between the moving belt and the contact surfaces of the belt switch. In particular with thin strip material, this can cause a transport inhibition. which leads to a build-up and an unfavorable directional reversal of the strip material.
  • This disadvantage also exists in the event that a fluid or water is sprayed onto the belt in the area of the belt switch, but insufficient forces are generated on the belt for the purpose of deflecting it into the guide shaft.
  • the invention is based on the object of creating a technology for winding a metallic strip with which an improved winding quality for the strip and, with regard to the spray water used for this purpose, an improved energy efficiency is achieved.
  • a method according to the present invention is used for winding a metallic strip, in particular a steel strip.
  • This method provides that the tape is moved in one transport direction, guided through a tape switch into a guide shaft and then wound onto a reel mandrel that is rotatably mounted about an axis.
  • a fluid is applied to the belt in the direction of the guide shaft in order to optimize the threading of the belt into the guide shaft.
  • at least one opening is formed in the belt switch through which the water is sprayed under pressure onto the belt.
  • water under pressure is used as the fluid, the water pressure being set such that a width-specific force between 0.1 N / [mm bandwidth] and 10 N / [mm bandwidth] is exerted on the band.
  • the water only hits the belt in the area of the belt switch is applied until the tape head has been wound onto the reel mandrel with up to three turns. If necessary, the spraying of water onto the strip in the area of the strip switch can already be stopped when the strip has been wound onto the reel mandrel with at least one turn or with two turns.
  • An alternative method according to the present invention is also used for winding a metallic tape. It is provided that the tape is moved in one transport direction, guided into a guide shaft through a tape switch and then wound onto a reel mandrel rotatably mounted around an axis, a fluid being applied to the tape in the direction of the guide slot in the area of the tape switch.
  • the belt switch there is at least one opening through which the water is sprayed onto the belt under pressure. Water under pressure is used as the fluid, with the water being applied to the strip in the area of the strip switch only until the strip head has been wound onto the reel mandrel with up to three turns. If necessary, the spraying of water onto the strip in the area of the strip switch can already be stopped when the strip has been wound onto the reel mandrel with at least one turn or with two turns.
  • the water pressure is set such that a width-specific force of between 0.1 N / [mm bandwidth] and 10 N / [mm bandwidth] is exerted on the band.
  • the invention is based on the essential knowledge that with the help of the water that is sprayed onto the belt in the area of the belt switch and leads to a width-specific force between 0.1 N / [mm belt width] and 10 N / [mm belt width] a pressure or a force is exerted on the tape which is sufficiently great that the tape is effectively deflected in direction into the guide shaft.
  • the deflection or guidance of the tape and its tape head is achieved essentially solely by the water sprayed onto the tape under pressure. This ensures that the mechanical contact of the tape head with the tape switch is advantageously minimized.
  • the belt switch thus only forms a "safety position", mechanical contact of the tape head with the belt switch then actually or at the latest causing the belt to be deflected or guided into the guide shaft.
  • Another essential aspect of the present invention is that when the tape is wound up, the energy efficiency with regard to the spraying of the water that is applied to the tape in the area of the tape switch is optimized by such an application or spraying of water the tape for the purpose of deflecting it into the guide shaft only takes place as long as the tape head has been wound onto the reel mandrel with up to three turns. If necessary, the spraying of water onto the strip in the area of the strip switch can already be stopped when the strip has been wound onto the reel mandrel with at least one turn or with two turns.
  • this nozzle or nozzles are designed in such a way that the water is applied to the belt over its entire length Width can be applied. This ensures that a force is exerted on the belt over its entire width by the water sprayed on it, in order to achieve a uniform change in direction or reversal in the direction of the guide shaft.
  • the water under pressure is applied to the belt in the area of the belt switch through at least one nozzle or a row of nozzles is deployed which, viewed in the direction of transport of the belt, is arranged upstream of a pivot point of the belt switch.
  • a nozzle or row of nozzles can also be arranged upstream of a tip of the belt switch, viewed in the direction of transport of the belt.
  • At least one opening is formed in the belt switch through which the water is sprayed onto the belt under pressure.
  • an opening can be designed in the form of a slot opening and extend over the width of the belt switch.
  • the water can be sprayed onto the belt under pressure in such a way that it has a directional component in the direction of transport of the belt. This avoids any artificial additional resistance which would otherwise arise from the spraying of water onto the surfaces of the belt.
  • the said directional component which is generated with or in the water sprayed onto the strip, optimizes the movement or guidance of the strip in the direction of the reel mandrel.
  • a transport fluid can be directed onto the belt within the guide shaft. It is useful here that this transport fluid has a directional component in the direction of the reel mandrel, which promotes the movement of the strip in the direction of the reel mandrel becomes.
  • This transport fluid can be compressed air and / or water under pressure. In any case, this transport fluid has the advantage that the strip is transported within the guide shaft in the direction of the reel mandrel with reduced frictional contacts that would otherwise arise with the boundary areas of the guide shaft.
  • the transport fluid is preferably applied or sprayed onto the surfaces thereof from both sides of the belt.
  • the water in the area of the belt switch and / or the transport fluid within the guide shaft are discharged as soon as the tape head of the tape is a predetermined distance from a driver device that is arranged upstream of the belt switch in the transport direction of the belt and comes into contact therewith for driving the belt in the transport direction, falls below upstream thereof.
  • the spraying of water under pressure in the area of the belt switch and / or the application of the transport fluid to the belt within the guide shaft is started shortly before the head of the moving belt reaches the driver device.
  • This "timing" in relation to the start of the application of the water under pressure or the transport fluid is implemented by defining the predetermined distance upstream of the driving device and can be monitored with the aid of a sensor which is arranged at the location of this predetermined distance. As soon as the head of the moving belt passes the sensor, a corresponding control signal is generated by the sensor and the application of the water under pressure in the area of the belt switch or the transport fluid within the guide shaft is initiated. It is accordingly ensured that the desired influencing or deflection of the direction of the tape actually starts immediately when the tape head of the tape reaches the tape switch.
  • the invention also provides a device for winding a metallic strip, in particular a steel strip, and comprises a reel mandrel for winding the band, a guide shaft which is arranged upstream of the reel mandrel, as seen in the transport direction of the band, a band switch, by means of which the strip is introduced into the guide shaft, at least one nozzle or row of nozzles arranged in the area of the strip switch, through which water can be applied to the strip under pressure, and a control device, by means of which the application of water onto the strip in the area of the strip switch can be controlled or regulated. At least one opening is formed in the belt switch through which the water can be sprayed onto the belt under pressure.
  • the control device is programmed in such a way that in the area of the strip switch the water is only applied under pressure to the strip until the strip with its strip head hits the reel mandrel with at least one turn, preferably with at least two turns, more preferably with up to three Turns has been wound.
  • the aforementioned device can have a first sensor which is arranged at a predetermined distance upstream of the driver device and is in signal connection with the control device.
  • the above-mentioned device can have a second sensor which is arranged adjacent to the reel mandrel and is in signal connection with the control device.
  • a signal from the second sensor it is possible to detect at what point in time the tape has been wound on the reel mandrel, to what extent or with what number of turns, in order, depending on this, to dispense or spray water onto the tape in the area turn off the belt switch.
  • the device according to the invention leads to the advantage of improved energy efficiency with regard to the spraying of water under pressure onto the belt in the area of the belt switch.
  • the spraying of water onto the tape is carried out only at the beginning of the winding process when the tape head of the tape is moved past the strip switch for the first time, this ejection being stopped as soon as the strip has been wound on the reel mandrel with at least one turn, preferably with up to three turns.
