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 the US 5,611,500 A (Smith ) or the US 5,845,868 A (Klerelid et al. ), or if a separate drive of the spool is provided, such as in the DE 197 48 995 A1 (Voith ), the contact pressure can not be set exactly because 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.
  • the DE 33 47 733 represents a winding device, in which also the position of the roller is determined. Also in the system according to the DE 197 48 995 the position of the spool is determined by a diameter measurement DE 38 05 950 describes 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 tambour, preferably during the entire reeling process, is mounted with its axis ends on force measuring devices for measuring horizontal forces for the 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.
  • the invention is further characterized in that the force measuring devices are provided in a horizontally displaceable holding device.
  • the force measuring devices are provided in a horizontally displaceable holding device.
  • the invention is further characterized in that the spool, 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.
  • 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, the exact adjustment of the pressure force even with small values possible.
  • 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. In this way, a very good lateral guidance of the belt is possible, with no friction losses and no lateral bleeding can occur.
  • Fig. 1 a plant according to the invention
  • Fig. 2 a section along line II-II in Fig. 1
  • Fig. 3 a section from Fig. 1 .
  • Fig. 4 a section along line IV-IV in Fig. 1 .
  • Fig. 5 a section along line VV in Fig. 4 .
  • Fig. 6 a section according to line VI-VI in Fig. 4 and Fig. 7 a section according to circle VII in Fig. 6 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. 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 Garvor 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 again 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 (contact force between drum 1 and support roller 4) 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, to keep the friction factors low here as well.
  • Fig. 3 now shows a section Fig. 1 representing the secondary arm 10.
  • the contact force A can be measured via the force measuring device 16 regardless of the position and loss-free, since no loss-prone 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 thereby detected by integrated in the cylinders 19 measuring systems.
  • Fig. 4 (Section IV-IV in Fig. 1 ) is recognizable. 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 along line VV in Fig. 4 , wherein here the structure of the support rollers 21 can be seen.
  • the support rollers 21 run on rails 27.
  • On the top and bottom surfaces 28 of the guide profile 26 can be seen.
  • Fig. 6 now shows a section according to line VI-VI in Fig. 4 which is laid by a guide roller 22.
  • 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 for sealing.
  • the created by this device cavity 29 is 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.
