Definitions

  • the invention relates to a method for winding a metallic strip according to the preamble of claim 1 and of claim 3, and a corresponding device according to the preamble of claim 12.
  • a respective band is guided by a driver device to a coiling about an axis coiler mandrel and then wound onto the coiler mandrel.
  • a guide shaft Between the driver device and the coiler mandrel is a guide shaft, which is traversed by the wound tape.
  • a band switch Adjacent to an opening of the guide shaft, a band switch is arranged, with which the band undergoes a change of direction and thus is guided into the guide shaft.
  • EP 2 512 701 B1 According to the state of the art is off EP 2 512 701 B1 .
  • WO 2016/091855 A1 and JP 2005305452 A the application of media or water on the tape in the area of the band switch known for cooling or transportation purposes.
  • the invention has for its object to provide a technology for winding a metallic strip, with an improved winding quality for the tape and in relation to the spray used for this purpose, improved energy efficiency is achieved.
  • a method according to the present invention is for winding a metallic strip, in particular a steel strip.
  • This method provides that the belt moves in a transport direction, is guided through a belt switch into a guide shaft and then wound onto a reel mandrel rotatably mounted about an axis.
  • a fluid is applied to the band in the direction of the guide slot in order to optimize the threading of the band into the guide slot.
  • water is used as the fluid under pressure, the water pressure being set such that a band-specific force of between 0.1 N / [mm bandwidth] and 10 N / [mm bandwidth] is exerted on the belt.
  • the water is applied to the band only in the region of the band switch until the band with its band head has been wound onto the reel mandrel with up to three turns. If necessary, the spraying of water on the band in the band switch already then be set when the tape has been wound with at least one turn, or with two turns, on the coiler mandrel.
  • An alternative method of the present invention also serves to wind a metallic strip.
  • the belt moves in a transport direction, guided into a guide shaft by a belt switch and then wound onto a coiler shaft rotatably mounted about an axis, wherein in the region of the belt switch a fluid is applied to the belt in the direction of the guide shaft.
  • the fluid used is water under pressure, wherein the water is applied to the band only in the area of the band-pass filter until the band with its band head has been wound onto the reel mandrel with up to three turns.
  • the spraying of water onto the belt in the region of the belt switch can already be set if the belt has been wound on the coiler mandrel with at least one turn, or with two windings.
  • the water pressure is adjusted such that a width-specific force between 0.1 N / [mm bandwidth] and 10 N / [mm bandwidth] is exerted on the belt.
  • the invention is based on the fundamental finding that with the aid of the water which is sprayed onto the belt in the region of the band-weft and leads to a width-specific force between 0.1 N / [mm bandwidth] and 10 N / [mm bandwidth] the band is exerted by a pressure or a force that is sufficiently great that the band thus experiences an effective directional deflection into the guide slot.
  • the directional deflection of the tape and its tape head is achieved substantially solely by the water sprayed under pressure on the tape. This ensures that the mechanical contact of the tape head is advantageously minimized with the band switch.
  • the band switch thus forms only a "safety position", wherein a mechanical contact of the tape head with the band switch then actually or at the latest deflecting or guiding the tape into the guide shaft causes.
  • Another essential aspect of the present invention is that when winding the tape, the energy efficiency with respect to the ejection of the water, which is applied to the band in the area of the band-weft, is optimized by such a spraying of water the tape for the purpose of its deflection into the guide shaft only as long as the tape has been wound with his tape head on the reel mandrel with up to three turns.
  • the spraying of water onto the belt in the region of the belt switch can already be set if the belt has been wound on the coiler mandrel with at least one turn, or with two windings.
  • this nozzle or nozzles are designed such that the water on the band over its complete Width can be applied. This ensures that a force is exerted on the band in its entire width by the water sprayed thereon in order to achieve a uniform change of direction or reversal in the direction of the guide shaft.
  • the water is applied under pressure to the band in the region of the band filter by at least one nozzle or a row of nozzles, which is arranged in the transport direction of the belt upstream of a pivot point of the band switch.
  • a nozzle or row of nozzles seen in the transport direction of the tape can also be arranged upstream of a tip of the band switch.
  • At least one opening is formed in the band switch, through which the water is injected under pressure to the band.
  • an opening may be formed in the form of a slot opening and extending over the width of the band-link.
  • the water can be injected under pressure on the tape so that it has a directional component in the transport direction of the tape. This ensures that an artificial additional resistance, which would otherwise arise from the spraying of water on the surfaces of the tape, is avoided.
  • the said directional component which is generated with or in the water ejected onto the belt, the movement or guidance of the belt in the direction of the coiler mandrel is optimized.
  • a transport fluid can be directed to the band within the guide shaft. It is expedient that this transport fluid has a direction component in the direction of the coiler mandrel, whereby the movement of the belt is conveyed in the direction of the coiler mandrel.
  • This transport fluid may be compressed air and / or water under pressure.
  • the transport fluid is sprayed from both sides of the belt onto the surfaces thereof.
  • the water in the area of the band switch and / or the transport fluid are discharged within the guide shaft as soon as the tape head of the tape a predetermined distance to a driver device, which is arranged in the transport direction of the tape upstream of the band switch and comes into contact therewith for driving the tape in the transport direction, falls below it upstream.
  • a driver device which is arranged in the transport direction of the tape upstream of the band switch and comes into contact therewith for driving the tape in the transport direction
  • This timing with respect to the commencement of application of the pressurized water or transport fluid is realized by establishing the predetermined distance upstream of the driver means and can be monitored by means of a sensor located at that predetermined distance location. As soon as the tape head of the moving belt passes by the sensor, a corresponding control signal is generated by the sensor and thus the discharge of the water under pressure in the area of the band switch or the transport fluid within the guide shaft is initiated. Accordingly, this ensures that the desired direction influencing or deflection of the tape actually begins immediately when the tape head of the tape reaches the tape switch.
  • the invention also provides an apparatus for winding a metallic strip, in particular a steel strip, and comprises a coiler mandrel for winding the strip, a guide shaft, which is arranged upstream of the coiler mandrel in the direction of transport of the strip, a strip diverter, by means of which the strip is guided in takes place in the guide shaft, at least one arranged in the region of the band switch nozzle or nozzle row through which water can be applied under pressure to the tape, and a control device by means of which the application of water can be controlled or regulated on the tape in the band ,
  • the control device is programmatically set up such that in the region of the band filter the water is only applied to the band under pressure until the band with its band head strikes the reel mandrel with at least one turn, preferably with at least two turns, more preferably with up to three Turns has been wound up.
  • the above-mentioned device may comprise a first sensor, which is arranged at a predetermined distance upstream of the driver device and is in signal communication with the control device.
  • a first sensor By means of this first sensor, it is possible to detect when the tape head of the tape arrives in the region of the tape switch, in order then to control the application of water to the tape accordingly.
  • the above-mentioned device may have a second sensor which is arranged adjacent to the coiler mandrel and stands in signal communication with the control device.
  • a signal of the second sensor it is possible to detect, at what time the band to what extent or with what number of turns on the reel mandrel has been wound up in response to which the application or ejection of water to the belt in the region of the band switch off.
  • the device according to the invention leads to the advantage of an improved energy efficiency with regard to the ejection of water under pressure onto the band in the area of the band-link. Namely, the ejection of water onto the tape is performed only at the beginning of the winding operation when the tape head of the tape is first moved past the tape switch, this ejection is stopped as soon as the tape on the coiler mandrel with at least one turn, preferably up to three Turns has been wound up.
