Definitions

  • the invention relates to a method for winding a Material web to a role in which the role in lies in a changing bed, by a loading roller the changing bed is pressed and at least during one Part of the winding process through a compressed air cushion is supported in the changing bed.
  • DE 195 24 905 A1 shows a further method for winding a material web to a role in which the Roll lies in a changing bed.
  • Can in the changing bed creates a compressed air cushion with the help of a blow box to partially reduce the weight of the roll relieve.
  • a pressure roller is at the beginning a specific line force of approx. 25 N / cm set. If a predetermined diameter the roller is reached, the support rollers move apart and the platen is lifted off.
  • the invention is based on a paper web described as an example of a material web. she is however, not limited to this, but may be with others Material webs are used in which similar Problems like paper occur. Example of this are cardboard or foils made of metal or plastic.
  • the winding hardness is determined, among other things, by a nip force influenced, which is in the nip between the winding roll and sets the support rollers that form the changing bed. In a first approximation, one can assume that the higher the nip force, the higher the winding hardness is.
  • the desired winding hardness curve can be done without additional Practically not implement measures.
  • the role is practically only from the winding tube. So it's relatively light, like that that due to the nip force only one low winding hardness would result.
  • With increasing Roll diameter also increases the weight of the roll and thus the nip force on the support nips, what the winding hardness would increase. It is therefore known to begin with of the winding process, a loading roller on the roll to let it rest, the load roller being the roller with a predetermined force in the changing bed. This allows the roll to be wound relatively hard, i.e. the winding hardness is in the area of the roll core or the winding tube high enough.
  • the invention has for its object the winding quality improve and make operations safer.
  • This task is carried out in a method of the type mentioned at the beginning Art solved in that the loading roller Roll with one during the entire winding process Presses a minimum load of 0.5 kN / m into the changing bed.
  • the compressed air cushion depending controlled by the load on the load roller becomes.
  • the pressure in the compressed air cushion also increased so that the nip force in the Supporting nips on the support rollers forming the changing bed can limit.
  • the compressed air cushion is, if necessary, under Consideration of other conditions, such as a minimum roll diameter, immediately to the burden of coupled the loading roller. Since this at least starts a predetermined roll diameter with a constant Force acts, one can have a correspondingly constant Generate counterforce using the compressed air cushion. Because the corresponding forces overlap linearly control is very easy.
  • the load roller is used to the Determine the diameter of the roll, using the compressed air cushion depending on predeterminable parameters the wound material web and the diameter of the Role is controlled. If the load roller on the circumference of the roller, then the location of the load roller information about the diameter of the Role. This diameter information allows under Consideration of the parameters of the material web, for example Weight per unit area or density, based on weight and conclude the associated weight of the role. Then from the weight deduce the nip force in the support nips of the roll. So if, for example, not only their strength, but also passes on their location to a controller, then the controller can use the air cushion relatively adjust exactly.
  • the compressed air cushion is preferably set such that that a predetermined maximum nip force between the Role and the support rollers forming the changing bed is exceeded. This limits the winding hardness.
  • the maximum nip force is preferably dependent of paper grade sensitivity in the range of 2 to 5 kN / m. This value has proven to be sufficient to produce the desired winding hardness, on the other hand but to protect the material web sufficiently.
  • a nip force curve between the roller and the support roller the entire winding process remains approximately constant.
  • the load from the load roller remains the resulting nip force, which is also taking into account the weight relief with the help of the compressed air cushion results, approximately constant.
  • this term is meant that certain variations are perfectly acceptable could be.
  • the changes remain below 25% of an average nip force curve.
  • the compressed air cushion is only advantageous from one predetermined roll diameter turned on, wherein this roll diameter with the load from the Loading roller is changed.
  • this approach one takes into account the fact that only from one predetermined roll weight actually relieves compressed air is necessary because only from a certain Roll diameter the roll weight so far increases that the nip force in the support nips increases the hardness could negatively affect.
  • By increasing the force of the load roller can now to shift the circumstances. If, for example, due to a troubled run of the role an increase in the The force of the load roller is necessary, the sum then one from load and weight assumed critical value if the otherwise usual Roll diameter has not yet been reached. In this In this case, the compressed air cushion is set up earlier.
  • Fig. 1 shows a winding device for winding a Material web 2 to a winding roll 6 '.
  • the web of material 2 is wound onto a sleeve 6, which rests in a changing bed 11 by two Carrier rollers 3, 5 is formed.
  • the changing bed 11 will with the help of a blow box 4, which is in the gusset below the support rollers 3, 5 are arranged, supplied with compressed air, i.e. A compressed air cushion can be controlled in the winding bed 11 be built to support the Serves winding roller 6 'and thus the bearing force of the Winding roll 6 'on the support rollers 3, 5 reduced.
  • the present Case designed as a piston-cylinder engine is, via a linkage 9 in the direction of the changing bed can be charged.
  • the sleeve 6 and later the winding roll 6 ' is pressed into the winding bed 11, So against the support rollers 3, 5.
  • the position of the winding roller 7 is also dashed located.
  • the angular position, i.e. an angle ⁇ , of the linkage 9 opposite A pivot point 13 is with the help of a sensor 12 recorded. Since the length of the lever linkage 9 is known is the position of the loading roller from the angle ⁇ 7 determine relative to the changing bed 11. This Location information can also be obtained in other ways , for example from the extension movement the engine 8. Finally, it is not necessary that the loading roller moves over a lever linkage 9 becomes. It is also conceivable that the loading roller 7 in a linear guide is arranged.
  • the position information of the sensor 12 becomes one Control device supplied.
  • the control device controls a force F via the motor 8 with which the loading roller 7 acts on the winding roll 6 '. How to continue explained below is the force of the load roller depending on the diameter of the winding roll 6 '. therefore are two different forces F, F 'in Fig. 1 indicated that at different diameters of the Winding roll 6 'or the sleeve 6 from the loading roller 7 are applied.
  • the control device also controls 10 also the pressure of the blow box 4, i.e. the Air pressure in the changing bed 11.
  • Fig. 2 some curves are now shown, based on whose invention is to be explained.
  • a curve 14 shows the line load, which increases with increasing Diameter of the winding roll 6 'without additional Measures would result.
  • the negative line load results from the fact that at the beginning of the winding process where the winding roll 6 'is still relatively light, the web 2 in the case of their entry via the support roller 3, the tendency has to lift the sleeve 6 out of the winding bed 11. For this reason, the load roller exercises in this area 7 a relatively large force. That power the loading roller is plotted in a curve 15.
  • the loading roller 7 with a relatively high force F in Winding bed 11 directed so that the winding tube 6 and the winding roll 6 'formed thereon with a relative high nip force or nip load is wrapped.
  • Winding roll between the nip force in the support nips the winding roller 6 'and the support rollers 3, 5 due to Up to now, the dead weight of the winding roll 6 'has increased the load by the load roller 7 continuously retracted until the load from the load roller 7 was practically barely noticeable.
  • the values were 0.2 kN / m.
  • the pressure in the changing bed 11 should depend on the paper type and its sensitivity be that the nip force in the support nips between the winding roller 6 'and the two support rollers 3, 5 is about 2 to 5 kN / m.
  • the web roll 6 'with the help of the loading roller 7 is pressed firmly into the changing bed on the one hand, to the desired high at the beginning of the winding process Generate winding hardness and at the same time eject it (Kick-out) the web of material from the To prevent changing bed. This holding or clamping function is maintained throughout the winding process.
  • the control prevents that the bearing force of the web roll 6 'on the Carrier rollers 3, 5 becomes so large that damage occurs. The control allows it, even with considerably larger ones Forces to work on the load roller 7, because the Compressed air relief for a correspondingly controlled Compensation provides.
