Definitions

  • the invention relates to a method and an apparatus for winding a material web, in particular a metal strip, wherein a collar is supported during the winding process by at least two rotationally driven support rollers (see, for example KR 1020040056824 A ).
  • a band-shaped material is wound into a winding roll, in which one strives for the most uniform possible edge coverage.
  • metallic rolling stock such as a steel strip or an aluminum strip
  • the rolling strip running out of a rolling mill is wound into a bundle.
  • a sample of the metal strip is subjected to an inspection.
  • a piece of the rolled strip is unwound by the Federal Government and wound back after checking.
  • the problem arises that with increasing unwinding length there is a risk that the rolled strip runs laterally.
  • the consequence of this is then a metal collar telescoped at least on the outer turns. From the end face of the metal collar protruding metal band can then be easily damaged during transport in subsequent process steps. Overall, the metal collar can be reduced in its value.
  • the weight force of the collar resting on the support rollers is generated by the inclination of support rollers or bottom rollers, a horizontal force component which is used to counteract the lateral running of a material web.
  • This is achieved by pivoting by means of a pivoting device, the two or more support rollers together about a pivot axis between a first, substantially horizontal position, in a second, with respect to the horizontal position inclined position.
  • the axes of the support rollers can be inclined in opposite directions to the lateral extent of the band with respect to the horizontal, one can maintain the edge coverage at the waistband when (re) winding a metal strip.
  • the two support rollers are inclined so that the web edge comes back to the end face.
  • the inclination of the support rollers can do so It will be understood that one end face is lowered with respect to the horizontal, depending on which side the web edge is running from the end face. But the inclination of the support rollers can also be done so that similar to a balance beam one end of the collar lowered and at the same time the other is raised.
  • the pivoting operation can be controlled manually in the simplest case, for example, by an operating staff watching the process when rewinding the metal strip. If visually a lateral bleeding of the metal strip is detected, then a corresponding tilting movement is triggered by an operating device by hand.
  • a metal collar In rolling mill technology, a metal collar, a so-called coil, can be for example 40 tons. To tilt this heavy weight, a correspondingly configured drive device is required, which is able to apply the force required for the pivoting movement.
  • This power generation can be done for example by one or more hydraulic piston-cylinder units, or by an electric drive in conjunction with a spindle.
  • the control of the axial tilt can also be done by an automatically operating device.
  • the weight of a metal collar is used very efficiently to produce a horizontal force component directed counter to the strip. Due to the axial inclination of the support rollers according to the invention it is achieved that after the inspection of a metal collar, the end faces are flat.
  • the pivoting device on a special support device in which the at least two rotationally driven support rollers are rotatably mounted.
  • the support device may for example be a metal frame which is designed in the manner of a balance beam, that is, the frame is pivotable relative to a pivot axis, for example by being centrally supported.
  • the pivot axis passes through the crossbar of the frame.
  • the frame is constructed so that spatially seen, the axes of rotation of the support rollers and the pivot axis intersect each other, but do not intersect.
  • the support rollers are each pivotable about a pivot angle, which is infinitely predetermined. This can be counteracted a very differentiated a bleeding of the material web. Again, the weight is used to prevent lateral bleeding of the band-shaped material. Compared to a lateral displacement of the support rollers, the pivoting process requires less energy.
  • the pivoting movement is a lowering movement, that is to say if the pivoting plane respectively spanned by the pivoting movement of the axes of rotation of the supporting rollers is perpendicular.
  • a suitable sensor can operate according to different measuring principles, for example tactile or non-contact, for example a Ultrasonic sensor or an optically operating system.
  • the web edge sensor supplies a position information that is fed to the pivoting device. When specifying the swivel angle, this position information is considered accordingly.
  • the technical design of such a pivoting device essentially comprises an information processing unit, for example a computer, which causes a drive device for generating the pivoting movement via corresponding control signals. Both are basically commercially available, can be used appropriately adjusted with little effort and therefore need not be explained in detail here in detail.
  • FIG. 1 and the FIG. 2 show in a schematic representation of the principle of the present invention. Shown is the situation of a covenant 1, which rests on two support or floor rolls 2, 3. Such a collar may for example be a metal collar.
  • a piece of a material web 14, hereinafter also referred to as a metal strip, rolled strip or rolling stock should first be unwound and then wound back again.
  • a rotary drive 7 sets the two rollers 2, 3 in a rotary motion.
  • the metal strip 14 thus runs in the direction of the strip running direction 10 toward the rotating metal collar 1. It may, as shown initially, come to an undesirable lateral bleeding of the metal strip 14.
  • the result is a telescoping of the metal collar 1, which is undesirable because protruding edges arise that can be damaged and affect the value of the metal collar.
  • a steering of the collar 1 tapered web 14 can prevent this.
  • this band deflection is carried out so that the support or bottom rollers 2 and 3, which form a so-called “winding trough” or a “winding bed” for the metal collar 1, are lowered or raised on the head or foot side. By this correction, a very good edge coverage of the metal collar 1 can be achieved.
  • the band steering can be basically controlled manually or automatically.
  • the force for the pivoting movement in the direction of the arrow D can be generated in various ways, for example hydraulically or electrically.
  • the axes of rotation 5, 6 of the two support rollers 2, 3 in the present example are parallel to one another and lie in a horizontal plane.
  • the unilateral lowering movement of the support roller axes 5, 6 takes place synchronously in the present embodiment, that is, the swept per unit time pivot angle is the same for both support rollers 2, 3.
  • the steering of the rolled strip can be controlled manually or automatically.
  • an automatic strip deflection is indicated by a web edge sensor 4, the sensor signal 13 of the pivoting device 11 is fed.
  • the pivoting device 11 includes a corresponding signal processing. This uses the sensor signal 13 as a control signal for a in FIGS. 1 and 2 not shown drive device.
  • FIG. 3 shows a possible embodiment of the invention, in which the axes of rotation 5, 6 of the support rollers 2, 3 are rotatably mounted in a frame member in each case end side in a support device 16 designed as a balance beam.
  • the frame part 16 is rotatable about a pivot axis 18.
  • This movement is produced by means of a pivoting drive 15, in the present example a piston-cylinder unit which acts on the right on the frame part 16 and moves either upwards or downwards on this side.
  • the collar axis 8 runs parallel to the inclination of the axes of rotation 5 ', 6' or 5 ", 6". Following its gravity, the collar 1 will follow the sloping side, whereby its own weight in the steering of the metal strip 14 can be exploited and a lateral bleeding can be counteracted in an efficient manner.
  • pivoting device 11 as consists essentially of the frame part 16 and the drive unit 15, need not be discussed here in detail, since these units can be assumed to be known or commercially available. It should also be noted again that the pivoting device 11 can be operated both manually and automatically.
  • the pivot axis 18 is symmetrical on the line of an axis of symmetry 17, which marks a central region of the winding device. As explained below, this is not absolutely necessary.
  • FIG. 4 illustrates this again in a spatial representation.
  • the pivoting movement according to the arrow 19 about the pivot angle 12 takes place in a vertical pivot plane 50 and 60, respectively.
  • FIG. 5 shows the arrangement of the two axes of rotation 5, 6 with respect to the pivot axis 18 according to the embodiment of FIG. 4 ,
  • the pivot axis 18 does not intersect the two axes of rotation 5, 6, but is located at a vertical distance therefrom.
  • the pivoting movement is again indicated, whereby the axis inclination between the position 5 ', 6' and 5 ", 6" is infinitely adjustable.
  • FIG. 6 shows the sketch in FIG. 6 another possible embodiment in which the pivot axis 18, the axes of rotation 5, 6 intersects. Again, every one of them is here both axes of rotation 5, 6 between the position 5 ', 6' and 5 ", 6" continuously adjustable.
  • the two axes of rotation 5, 6 are parallel to each other and extend approximately in a horizontal plane. But this is not mandatory. It also seems possible that the two axes of rotation 5, 6, although parallel to each other, but with respect to the pivot axis 18 have a different distance.
  • the pivoting movement can be carried out so that the opposite end side is lowered or raised.
  • the pivoting movement can also according to a balance beam lowering one side, raising the other side causes.
  • the required detection of the web edge can be realized in different ways, for example, touching or non-contact.
  • the pivoting device 11 may be formed in different ways, such as a hydraulic drive and / or an electric drive.
  • the lowering movement can be realized by means of a spindle or with another gear.
  • the drive of the swing frame can of course also by several linear drives, each end in the area of the bearings of the support rollers attack, be realized. It is also conceivable that the pivoting movement is generated by a rotary drive.
  • a preferred field of application of the invention is the winding of a metal strip, in particular during inspection or sampling.
  • the invention is not limited to this application example of rewinding a metal strip, but in principle applicable for the winding process of any material web, such as a plastic web or a paper web or a web of fabric or other material.
