Definitions

  • the invention relates to a roll winding device for a material web roll with a roll relief device, the one blow box with a compressed air connection having.
  • the invention is based on a paper web described as an example of a material web. She is but not limited to paper web rolls. Similar Problems like paper web rolls also arise when winding other rolls, for example Cardboard or foil made of metal or plastic.
  • the invention is both when winding also applicable when unwinding web rolls. In both cases, similar problems arise be solved in the same way.
  • the invention is as follows but based on the winding of a paper web described a paper web roll.
  • the processor of paper web rolls for example Print shops, want bigger and bigger web rolls, So a larger stock of paper web around the makeready times to keep small.
  • the trend is currently broad of over 3 m and roll diameters of over 1.5 m.
  • the winding tube is that is usually designed as a cardboard sleeve, no more able to provide the necessary rigidity.
  • A is used to produce such an air cushion Blow box, which has a compressed air connection with compressed air is supplied.
  • This blow box is attached to the paper roll pivoted as soon as their diameter one certain value of e.g. 500 mm. To avoid Damage to the paper roll must be between you and the blow box remain a crack, due to the significant energy losses due to outflowing Compressed air are created. It also changes permanently the pressure conditions in the blow box and thus the degree of relief, especially the weight of the paper roll as a result of winding up or unwinding a change is exposed.
  • the invention has for its object the energy consumption in the case of roll relief by compressed air to keep small.
  • This task is done with a roll winding device of the type mentioned in that the Compressed air connection has a control device that a gap between the web of material and the Blow box regulates to a predetermined setpoint.
  • the gap size can be set to a relatively small value, for example 0.5 mm. As a control device in the compressed air connection can work relatively quickly, too largely ensured with these small gap widths, that an accidental placement of the web roll omitted on the blow box. With small ones Gaps are also less compressed air losses. It can be observed that one with such Control achieve much more stable pressure conditions can.
  • This gap is primary crucial for the escaping air. He delivers in addition for all the roll diameters in question a reliable control variable. With smaller ones The web of material naturally dips in diameters deeper into the blow box than with larger ones Roll diameters. If the gap at the edge of the blow box is monitored in the circumferential direction, then plays this immersion no longer matters.
  • the sensor device only needs at least one distance sensor, if necessary, a distance sensor for both edges. Such distance sensors are known per se.
  • They can be designed without contact, for example as an optical sensor, or they can be mechanical work, for example, by a tracer roller, the Blow box is attached to the circumference of the web roll is present. The deflection of the feeler roller opposite the material web roll then gives a statement about the Distance of the material web roll to the edge of the blow box.
  • the sensor device as Tracer role is formed, which extends over the entire axial expansion of the blow box extends. Then can the sensor device in addition to the measuring function perform an additional sealing function. This is from particularly advantageous if on both sides of the blow box such a feeler roller is used.
  • the blow box advantageously has a shorter axial one Extension as the web roll.
  • the winding roll sags most in its axial center. It is therefore sufficient in most cases if it is in this area, i.e. supported on both sides of their axial center becomes. Accordingly, the compressed air supply restrict to a smaller width what again keeps energy consumption low. It can be also easier to make sure that the desired gap between the blow box and the winding roll on the shorter length has sufficient constancy.
  • sealing tapes are therefore in addition to theirs Internal stress on the face of the blow box pressed. This improves the tightness.
  • the sealing tape at least low-friction on its side against the blow box interacts with the outer wall of the blow box.
  • low-friction material combinations can be realized in that the sealing tape made of polytetrafluoroethylene (Teflon) or another Plastic is formed during the blow box is made of stainless steel or another metal.
  • Teflon polytetrafluoroethylene
  • the front it is also possible for the front to coat the blow box with a plastic, correspondingly good with the material of the sealing tape cooperates.
  • a roll winding device 1 shown in FIG. 1 is used to wind or unwind a paper web or a another material web 2 on a material web roll 3.
  • the role 3 is here in not shown Wisely held on its central axis.
  • blow box 4 On either side of the axial center of the roll 4 arranged, which is also on both sides of a vertical extending plane extends through the roller axis.
  • the blow box 4 has a compressed air connection 5, through the compressed air, i.e. Air with increased pressure, in the blow box 4 can be blown.
  • the compressed air builds a pressure pad in the blow box 4, which the role 3 relieved. This creates between roll 3 and the blow box 4 on both boundary walls 6, 7 a gap 8, 9 in the circumferential direction of the roller 3 that the compressed air can escape.
  • a sensor 10 is provided, the size of the gap monitored.
  • the sensor 10 is connected to a controller 11 which between the compressed air connection 5 and a compressed air feed line 12 is arranged.
  • the controller 11 is designed as a flow regulator for the compressed air. It regulates the air flowing into the blow box 4 so that the gap 9 assumes a predetermined thickness. This Thickness, for example 0.5 mm, is used throughout Maintain the winding process at least from the time where the roller 3 has reached a diameter that is sufficient so that the roller 3 over the two walls 6, 7 of the blow box 4 survives.
  • the controller 11 can then ensure that the mean the two columns 8, 9 remains constant and simultaneously a predetermined minimum value of the thickness of the Columns 8, 9 are not undercut.
  • the regulator 11 only regulates the thickness of the column 8, 9 in Circumferential direction of the roller 3.
  • each sealing tape 17th is guided over four pulleys 18-21 as an endless belt, the upper two guide rollers 20, 21 with With the help of springs 22, 23 or other clamping devices so in Direction on the roller 3 are biased that the upper Run 24 of the sealing tape 17 at least in an angular range on the circumference of the roll 3, which is sufficient to cover the end faces 15, 16 of the blow box 4.
  • the sealing tape 17 has a thickness that is larger than the largest possible gap between the end faces 15, 16 of the blow box 4 and the scope of the roll 3, this gap of course only from the diameter is to be taken into account from which the material web roll 3 protrudes beyond the edges 6, 7 of the blow box.
  • the air losses are limited to Columns 8, 9, the strength of which is regulated.
  • the Regulation expediently takes place here in that the controller 11 is designed as a flow controller, which the Quantity, i.e. the volume that flows into the blow box 4 Air depending on the strength of the Column 8, 9 regulates. If columns 8, 9 enlarge, then the amount of air is reduced. If the Reduce column 8, 9, then the air volume is increased. Alternatively, you can also use a pressure regulator use.
