Definitions

  • the invention relates to a device for the continuous winding of a fibrous web, in particular paper, such as tissue web, wherein the web is guided over a carrier drum and subsequently wound on a winding device.
  • 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, as for example US 5,611,500 A (Smith) or US 5,845,868 A (Klerelid et al .) Show, or if a separate drive of the main cylinder is provided, such as in DE 197 48 995 A1 (Voith), the contact pressure can not be set exactly because there are too many places where incalculable losses, eg caused by friction , 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.
  • US 4,552,317 describes a take-up for a plastic web in which force measuring devices are provided which measure the weight of the roll. By means of an angle encoder then the contact force is calculated. The goal of this implementation is to achieve linear settings. Again, this system is far too inaccurate for the production of tissue paper. Also in DE 36 27 463, the pressure is calculated by measuring the position and by means of other default variables. In JP 61 075758 and JP 61 155147, the force against a fixed wall is determined, from which then a nip force is calculated. A direct measurement is not possible with this disorder. DE 198 18 816 relates to a winding machine in which the drum rests on the rails and also the diameter increase is measured.
  • DE 33 47 733 represents a winding device, in which also the position of the roller is determined. Also in the system according to DE 197 48 995, the position of the spool is determined by a diameter measurement DE 38 05 950 bequat a rewinder in which the pressure rollers are pressed by hydraulic cylinders and the pressing pressure is measured.
  • the aim of the invention is therefore to propose a device in which a good controllability is given during the winding process even at low contact pressures.
  • the invention is therefore characterized in that the spool, preferably during the entire Aufrvllvorganges, is mounted with its axis ends on force measuring devices for measuring horizontal forces for lossless measurement of the nip force. For a direct and lossless measurement of the contact force is possible, with a uniform paper quality over the entire winding process can be guaranteed.
  • a favorable development of the invention is characterized in that the force measuring devices are provided in a horizontally displaceable holding device. Thus, a constant force direction and easy transfer of the (controlled) pressure force can be ensured.
  • a favorable development of the invention of the invention is characterized in that the tambour, preferably during the entire Aufrollvorganges, is mounted on force measuring devices. For a direct and lossless measurement of the contact force is possible, with a uniform paper quality over the entire winding process can be guaranteed.
  • a favorable development of the invention is characterized in that the force measuring devices are provided in a horizontally displaceable holding device. Thus, a constant force direction and easy transfer of the (controlled) pressure force can be ensured.
  • An advantageous embodiment of the invention is characterized in that the horizontally displaceable holding device is provided with support rollers which run in guide profiles, wherein the guide profiles are sealed by a vertically running band. This ensures a safe and low-friction displacement, which allows an exact adjustment of the pressure force even at low values.
  • a favorable development of the invention is characterized in that the endless belt consists of fabric, plastic or steel. In this way, depending on the requirement and environment, the cheapest version can be found.
  • the vertically running band is designed as an endless belt and is deflected over two rollers provided at the ends of the guide profiles. This achieves a friction-free seal.
  • a favorable embodiment of the invention is characterized in that the deflection rollers have trapezoidal grooves for guiding the band, wherein the endless band has at least one trapezoidal profile which engages in the trapezoidal grooves of the deflection rollers.
  • Fig. 1 is a plant according to the invention
  • Fig. 2 is a section along line II-II in Fig. 1
  • Fig. 3 is a detail of Fig. 1
  • Fig. 4 is a section according to line IV-IV in Fig. 1
  • Fig. 5 is a section along line VV in Fig. 4,
  • Fig. 6 is a section along line VI-VI in Fig. 4 and Fig. 7 shows a detail according to circle VII in Fig. 6.
  • the mode of operation of the device will now be described with reference to FIG.
  • 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. 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.
  • Fig. 2 shows a section along line II-II in Fig. 1.
  • the Haltevor device 11 consists of a receiving part 12 with two hydraulically operated clamping levers 13, 14 and sits on a force measuring device 16 which in turn is mounted on the sliding member 17.
  • the entire unit is also called secondary arm 10.
  • this drive 18 is coupled on the drive side TS to the winding shaft 1 and the drive 6 disengaged in the primary arm 3.
  • the horizontal nip force is produced via the secondary arm 10 via a respective hydraulic cylinder 19 on the driver side FS and drive side TS and regulated by the force measuring devices.
  • 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 10, 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 the drum 1 and carrier drum 4 capture. Vertical components from the drives or from the changed net weight of the paper reel do not influence the measured values.
  • the detected measured value signals control the movement of the two hydraulic cylinders 19, so that it is ensured that an absolute parallel operation of the secondary arms 10 on the driver side FS and drive side TS and a preselected Nipkraftverlauf (constant or variable) is secured throughout the winding process.
  • the displacement part 17 of the secondary arm 10 is mounted on horizontally running support rollers 21, which run in guide rollers 20, in order to keep the friction influences low here as well.
  • FIG. 3 now shows a detail of FIG. 1, which represents the secondary arm 10.
  • the contact force A can over the force measuring device 16 are measured independently of the position and without loss, since no lossy intermediate elements are present.
  • the displacement part 17 of the secondary arm 10 is displaced by the hydraulic cylinder 19, so that always the same contact pressure A of the winding shaft 1 acts against the support roller 4.
  • the respective position of the secondary arm 10 is detected by integrated in the cylinders 19 measuring systems.
  • These support rollers 21 are protected from contamination by a special device, as can be seen from Fig. 4 (section IV-IV in Fig. 1). It consists of two pulleys 22 per guide unit 26 (a total of 8 pulleys for a system), wherein a roller 22 is tensioned. To the pulleys 22 runs an endless belt 23 made of fabric, plastic or steel. At this band 23, the support rollers 21 are fixed, which by way of example only one support roller 21 is shown here.
  • FIG. 5 now shows a section according to line V-V in FIG. 4, wherein the structure of the carrying rollers 21 can be seen here.
  • the support rollers 21 run on rails 27.
  • On the top and bottom surfaces 28 of the guide profile 26 can be seen.
  • the guide rollers 22 are provided with, for example, two trapezoidal grooves, wherein on the endless belt 23, for example, two trapezoidal profiles 24 are applied, which engage in the grooves of the guide rollers 22 and thus prevent lateral bleeding.
  • the number of grooves may vary depending on the bandwidth.
  • FIG. 7 shows a section VII in FIG. 6. It can be seen here very clearly lateral slots 25 on the wall 28 of the guide profile 26 which serve to guide the belts 23 and to seal. In addition, the through this Device created cavity 29 protected by continuous injection of compressed air against the ingress of dust.
  • the measurement and regulation of the nip force can thus be carried out very well and safely even with the smallest contact pressures.
  • the invention is not limited to the illustrated examples. Besides hydraulic cylinders, e.g. also pneumatic cylinders are used.
