Definitions

  • the invention relates to a double carrier roller winder with a first driven support roller and a second driven carrier roller, which form a changing bed, in which at least one winding roll is arranged, and with a loading device.
  • Such double carrier roll winder are often in the Connection to a roll cutter used to the partial webs that are made in the roll cutter a material web has been cut in the longitudinal direction are to be wound into winding rolls.
  • Paper webs are available in widths of up to 10 m manufactured. Consumers, such as printers, but usually only require paper web widths from 0.8 to 3.8 m.
  • Double carrier roller winders have the advantage that you can have several Winding rolls side by side, i.e. with a common one Winding axis, can wrap. The sum of the axial lengths the winding rolls then correspond to the width of the original one Paper web. The same applies to others Material webs, for example plastic films or metal.
  • the winding rolls should be constructed so that they in Region of their core have a relatively high hardness, i.e. in the core area the paper (or another Material web) can be wound particularly tightly.
  • the Hardness in the middle area should be slightly lower and remain constant or from the inside out fall off continuously.
  • the invention is based, another object Possibility of influencing the winding hardness specify.
  • This task is done with a double carrier roll winder of the type mentioned in that a further drive device is provided, which on the Scope of the winding roll acts.
  • the further drive device thus drives the winding roll in addition to the two support rollers. So that is it is possible to have a greater drive power than before transfer to the winding roll.
  • the transmission larger Drive power on the winding roll failed So far, among other things, the fact that one is too big could not ensure the drive torque of the support rollers, that the idler rollers slip-free compared to the Moving winding roll.
  • the winding roll just off your winding tube with possibly a few there is wound material web layers is the winding power transferable from the carrying rollers to the winding roll limited.
  • the loading device train as a load roller and drive it. So far, the drive was not suitable, including that To drive the winding roll. He only served that Apply momentum for the load roller in order to to prevent the winding roller from the loading roller must drag along.
  • the Drive device actually active on the winding roll acts and drives them.
  • the further drive device at least in a winding section at the beginning of a winding process at least 15%, in particular at least 20% of the drive power for the winding roll. This is a relatively significant proportion of the drive power. Accordingly, the transferable to the winding roll Drive power increased considerably.
  • the drive device is preferably located with a Contact pressure distribution on the winding roll, the resultant is directed into the changing bed. You use So the drive device also from that Keep the winding roll in the changing bed and there against the Press rollers. You can also achieve this a better frictional connection between the winding roller and the support rollers and thus increases the possibility of drive power from the support rollers to the circumference of the Transfer winding roll.
  • the drive device through the Load device is formed.
  • You combine in the load device therefore has two functions: firstly a contact pressure is applied to the winding roll, which is necessary at least at the beginning of the winding process is the necessary for the winding process To generate nip pressures on the support rollers. On the other hand an additional drive power is applied, which the possibility of train control and thus the Control of winding hardness expanded considerably.
  • the drive device a larger share of the drive power of the Winding roller as the first carrier roller.
  • the second carrier roller should provide a larger share of the drive power.
  • the other drive device should also be one provide a larger share of the drive power. This will keep the possibility of having the winding roll with a relatively big moment that doesn't in the first nip, i.e. between the first carrier roller and the winding roll, is applied so that immediately behind this nip an increased web tension is generated can be. This web tension can be in the winding roll "Wrapped up", creating the desired one high winding hardness results.
  • the predetermined winding section is preferably sufficient up to at least 40% of the final diameter of the winding roll. As the roll diameter increases, the proportion of Drive power applied by the first carrier roller becomes. This ensures that the winding hardness decreases with increasing roll diameter.
  • a control device is preferably provided which the drive power on the two support rollers and on distributed the drive device. You can then make certain Drive patterns according to which the drive power is distributed. For example, one can use a drive power distribution start at the first Carrier roller at the beginning of the winding process 10%, the second Carrier roller 40% and the drive device 50% of the total Provides drive power. If the winding roll has reached a diameter of 500 mm, you can Share of the second support roller and the drive device swap. With a diameter of 1000 mm, the Share of the drive device in the drive power be lowered to zero while the first idler roller 30% and the second carrier roller 70% of the total drive power contributes. At the end of the wrapping process, for example at 1500 mm in diameter, the first one Carrier roller 45% and the second carrier roller 55% of the drive power apply. Of course it is also possible to provide other distribution courses.
  • the loading device is advantageously used as a loading roller trained that an elastic surface having. So the surface is within certain limits compliant.
  • the load roller on the winding roll is pressed, there is a larger contact area, so that despite a predetermined line load Compressive stress can be kept within certain limits. This protects the material web,
  • the Drive device over a correspondingly larger Circumferential section on the winding roll, so that the contact surface for torque transmission larger and therefore becomes more effective.
  • Such a configuration is especially of Advantage if several winding rolls in a row in the changing bed are arranged, and the loading roller is provided for several winding roll together, wherein the resilience of the surface is sufficient to despite smaller diameter differences between neighboring ones Winding rolls one system of the load roller on all Ensure winding rolls.
  • the winding rolls in practice not all of them are absolutely identical build up.
  • the elastic load roller can still be used within certain limits Density and the diameter of the individual winding rolls design equally. This results in a self-steering Effect.
  • the winding rolls with a larger diameter penetrate further into the elastic surface of the Loading roller on. So here is the compressive stress greater.
  • the diameter increase is thereby more inhibited than the winding rolls, which are smaller Have diameters and therefore not that far penetrate the elastic surface of the load roller.
  • the diameter increase can take place faster, so that the diameters align. The overall result is then during the winding process a relatively even increase in diameter for all winding rolls.
  • a winding device shown schematically in FIG. 1 1 has a first support roller 2 with a drive 3 and a second support roller 4 with a drive 5. Between the two support rollers 2, 4 is a winding bed 6 is formed, in which a winding roll 7 is arranged.
  • the winding roll is at the beginning with solid lines of the winding process shown. It exists to this Time practically only from a winding tube with one Diameter of about 100 mm, for example.
  • a paper web 8 is wound onto the winding tube.
  • the Paper web 8 can, as shown, from the side between the sleeve 7 and the first support roller 2.
  • a loading roller 9 acts on the winding roller 7.
  • the loading roller 9 also has a drive 10.
  • the drive 10 can both from an axial end also act on the load roller from both ends.
  • the loading roller 9 has an elastic Layer 11 on its perimeter. It is about a schematic lever linkage 12 shown with a force F resilient in the direction of the changing bed 6 works.
  • the force F is represented here by an arrow.
  • the drives 3, 5, 10 are with a control device 13 in connection with the distribution of drive power controls the individual drives.
  • a curve TW 1 shows the drive power of the first support roller 2 over the diameter of the winding roll 7, 7 '.
  • a curve TW 2 shows the corresponding course of the drive power of the second support roller 4, and a curve BW shows the corresponding course of the drive power of the loading roller 9. It can be seen from this that at the beginning of the winding process the drive power is mainly applied by the second support roller 4 and the loading roller 9.
  • the first carrier roller 2 on the other hand, only makes an insignificant contribution to the total drive power. It can even be seen that the load roller 9 acts on the winding roller 7 with a greater drive power than the second support roller 4. If one wishes to reproduce a share of the power, the following table shows, for example: diameter Share of roller 2 Share of load roller Share of roller 1 102 mm 40% 50% 10% 500 mm 50% 40% 10% 1000 mm 70% 0% 30% 1500 mm 55% 0% 45%
  • the decreasing with increasing winding roll diameter Power is through a slightly smaller arrow F 'shown.
  • the elastic layer 11 of the load roller 9 has two effects. First, it increases the contact area between the loading roller 9 and the winding roll 7, so that the torque transmission is larger and so that it becomes more effective.
  • FIG. 2 There are schematic three winding rollers 7A, 7B, 7C, which rest on the first support roller 2.
  • the second carrier roller 4 is not visible.
  • the winding roll 7B although it has a partial web is wound, cut from the same material web becomes like the partial webs of the winding rolls 7A and 7C, a slightly smaller diameter. The diameter differences are exaggerated here, however shown large.
  • the elastic layer 11 in the area the winding rollers 7A and 7C more compressed.
  • This increases the surface pressure.
  • the increase in diameter the two winding rollers 7A, 7C becomes something more inhibited than the diameter of the middle winding roll 7B, the elastic layer 11 is not so must compress strongly. Accordingly, you will in a relatively short time due to the larger diameter enlargement set the same diameter again as with the adjacent rollers 7A and 7C as well. It This results in a self-regulating effect, so that in Changing bed 6 several winding rolls 7A-C wound simultaneously can be arranged axially one behind the other are.
