Definitions

  • the invention relates to a device for the continuous winding of a particularly high-volume.
  • Tissue web according to the preamble of claim 1 ( WO 97/22543 ).
  • Such devices have long been known in the manufacture of paper webs.
  • a disadvantage of the known devices is that either the contact pressure of the spool on the support roller is such that the spool is driven by the force generated by friction, or if a separate drive of the spool is provided, the contact pressure can not be set exactly there are too many places where incalculable losses, eg due to friction, occur.
  • the predetermined pressure which is set in the contact pressure cylinders, therefore, does not define the actual contact force between the carrier drum and drum.
  • a low contact pressure is desired in order not to destroy the high volume again by the contact pressure.
  • the contact pressure is only inaccurately adjustable and the losses due to friction in the mechanical parts are already above the required contact pressure, so that an exact control can not be done.
  • the contact pressure is measured and adjusted.
  • the weight of the spool and the paper roll are measured and frictional forces are calculated.
  • the regulation of the contact pressure can be done only in a gradation of 0.1 kN / m, but this is too imprecise for especially high-volume tissue papers.
  • the plant according to the WO 93/24401 can measure the nip force only inaccurately, and therefore measures a reference value, which should also include the losses, which are already in the order of the required nip force.
  • the aim of the invention is therefore to propose a device in which a good controllability is given during the entire winding even at low contact pressures.
  • the invention relates to a device for the continuous winding of a particularly high-volume tissue web according to claim 1.
  • a favorable development of the invention is characterized in that the tambour is mounted in a horizontally displaceable holding device on force measuring devices.
  • the combination of force measuring devices in the primary arm and in the secondary arm (displaceable holding device) ensures a constant contact force of the spool against the carrier drum during the entire winding process. This then leads to a constant quality of the paper from the first moment of Aufwickeins.
  • the rejects can therefore be reduced to a minimum (eg splices).
  • Fig. 1 a plant according to the invention
  • Fig. 2 a section from Fig. 1
  • Fig. 3 a section along line III-III in Fig. 2 represents.
  • the winding shaft (drum) 1 is inserted via a lowering device 2 in the primary arm 3 and clamped vertically vertically above the carrier drum 4.
  • a geared motor 6 On the driver's side FS is a geared motor 6, which is slidably mounted on a plate in the axial direction mounted. This is coupled to the winding shaft 1 to bring them to machine speed.
  • the primary arm 3 is then rotated by means of a pivoting device 7 as long as the axis of the carrier drum 4 until the winding shaft 1 touches on this.
  • the winding shaft 1 takes over by means of a suitable device, the paper web P in full width and starts to wind up and thereby increases its diameter.
  • the required contact force between the winding shaft 1 and the carrier drum 4 is applied and controlled by hydraulic cylinders 8, which are equipped with a force measuring device 10. In this case, the compensation of the weight of the winding shaft 1 is taken into account.
  • the primary arm 3 is now further pivoted about the axis of the carrier drum 4 until the winding shaft 1 comes in a horizontal position.
  • the thickness of the paper roll increases continuously up to a maximum of 350 mm.
  • the outer part of the primary arm 3 moves telescopically outwards. It is guided on roller bearings 9 in order to minimize the effects of friction on the nip force.
  • the paper roll is placed on a horizontally displaceable holding device 11 and clamped.
  • the holding device 11 consists of a receiving part 12 with two hydraulically actuated clamping levers 13, 14 and sits on a force measuring device 16 which in turn is mounted on the sliding part 17 again.
  • the entire unit is also called secondary arm.
  • a sliding in the axial direction geared motor is connected to the holding device 11.
  • the next winding shaft 1 is prepared in the primary arm 3.
  • the paper roll Once the paper roll has reached the desired size, it is pulled away from the carrier drum 4, set the new winding shaft 1 in the primary arm 3 in the Anwickelposition on the carrier drum 4 and the full paper web P taken. After ejection of the finished paper roll from the secondary arm this moves back to the carrier drum 4 and then takes over the new winding shaft 1 from the primary arm 3.
  • the force measuring devices 16 are designed such that they only the actually applied horizontal forces in the nip between drum 1 and carrier drum 4th to capture. Vertical components from the drives or from the changed net weight of the paper reel do not influence the measured values.
  • the detected measurement signals control the movement of the two hydraulic cylinders 19, so that it is ensured that an absolute parallel operation of the secondary arms on the driver side and drive side and a preselected Nipkraftverlauf (constant or variable) is secured throughout the winding process.
  • the displacement part 17 of the secondary arm is mounted on horizontally running support rollers 21 in order to keep the friction influences low here as well.
  • Fig. 2 shows a section Fig. 1 representing the primary arm 3.
  • the position of the winding shaft (drum) 1 is shown, in which the drive 6 takes over the winding shaft 1.
  • the entire primary arm is pivoted in the direction of rotation of the carrier drum 4.
  • the winding roll 1 is unrolled by a gate 23 by means of a roller 24 along a guide plate 25 and thus approaches the surface of the carrier drum 4.
  • the paper is torn off and on, with the the same peripheral speed as the carrier drum 4, ongoing winding shaft 1 immediately wound up.
  • the contact force of the winding shaft 1 and the carrier drum 4 and also the travel of the cylinder 8 is continuously measured and regulated according to the specifications.
  • the winding process continues until the horizontal position is reached.
  • the winding shaft 1 is transferred to the force measuring devices 16 in the holding device 11, so that the spool 1 is mounted during the entire Aufrollvorganges on force measuring devices, whereby a uniform paper quality over the entire winding process can be guaranteed. This is desirable especially for high volume tissue papers.
  • Fig. 3 now shows a cut in Fig. 2 according to line III-III. It can be seen here well the storage of the primary arm 3 by means of the roller bearings 9 and the pressure cylinder, which performs the telescopic movement.
