Definitions

  • the invention relates to a device for continuous winding a fibrous web, in particular paper, for example tissue web, the web being guided over a carrying drum and subsequently on a reel is wound up with a horizontally displaceable Holder.
  • Such devices have been in the manufacture of paper webs known for a long time.
  • a disadvantage of the known devices is that either the contact pressure of the drum on the support roller is such that the reel is driven by the force generated by friction or if a separate drive for the reel is provided, the contact pressure cannot be set exactly because there are too many places where there are incalculable losses e.g. by friction arise.
  • the specified pressure in the pressure cylinders is therefore not defined as the actual contact pressure between carrying drum and drum.
  • tissue paper with high Volume a low contact pressure is desirable to the high volume not to be destroyed again by the contact pressure.
  • the contact pressure is only imprecise adjustable and the losses due to friction in the mechanical parts already above the required contact pressure, so that an exact Regulation cannot take place. In previous systems, one also occurs Contamination of the guide profiles on what, among other things, too jerky movements and thus to a faulty paper web leads.
  • the aim of the invention is to achieve a smooth horizontal movement To enable winding roll (drum).
  • the invention is therefore characterized in that the horizontally displaceable Holding device is provided with idlers, which are in guide profiles run, the guide profiles by a vertically running Tape are sealed. This can contaminate the guide profiles and the resulting jerky movement of the holding device be avoided.
  • the vertically running belt is designed as an endless belt and over two deflection rollers provided at the ends of the guide profiles. This reduces friction losses to a minimum.
  • a favorable embodiment of the invention is characterized in that that the endless belt is made of fabric, plastic or steel. So the appropriate band can be selected.
  • a favorable further development of the invention is characterized in that that the deflection rollers have trapezoidal grooves for guiding the belt, the endless belt having at least one trapezoidal guide profile, that engages in the trapezoidal grooves of the pulleys. So that becomes a ensures secure guidance of the belt and a lateral displacement prevented.
  • An advantageous development of the invention is characterized in that that slots are provided for guiding the tape, which the tape edges enclose. A good seal can also be achieved with this become.
  • a favorable embodiment of the invention is characterized in that that the cavity between the guide profile and the band is caused by compressed air is acted upon. This makes it possible to keep even the smallest dust particles away.
  • a favorable further development of the invention is characterized in that that the holding device has a force measuring device. So that can the pressing force of the winding roll on the support roll directly and exactly be measured.
  • An advantageous embodiment of the invention is characterized in that that the sliding holding device with pressure cylinders, in particular Hydraulic cylinders is connected, the pressure cylinder with a control and / or control device are connected. So you can always get an exact one continuous movement of the holding device can be ensured, so that the contact pressure can be kept constant.

  • the winding shaft (drum) 1 is via a lowering device 2 inserted in the primary arm 3 and hydraulically vertical clamped over the drum 4.
  • a Geared motor 6, which is arranged on a plate in the axial direction is assembled. This is coupled to the winding shaft 1 to this to bring up to machine speed.
  • the primary arm 3 is now moved around by means of a swivel device 7 the axis of the support drum 4 rotated until the winding shaft 1 on it touches down.
  • the winding shaft 1 takes over with the help of a suitable one Device the paper web P in full width and starts winding it up and increases its diameter.
  • the required contact pressure between winding shaft 1 and carrier drum 4 is via hydraulic cylinder 8, which are equipped with a force measuring device, applied and regulated. This also compensates for the weight of the winding shaft 1 considered.
  • the primary arm 3 is now further around the axis of the Carrier drum 4 pivoted until the winding shaft 1 in a horizontal position comes.
  • the thickness of the paper roll increases continuously to a maximum 350 mm too.
  • the outer part of the primary arm 3 moves telescopic to the outside. It is guided on roller bearings 9 to the To keep the influence of friction on the nip force as low as possible.
  • the paper wrap is placed on a horizontally displaceable holding device 11 and clamped.
  • Fig. 2 shows a section along line II-II in Fig. 1.
  • 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.
  • the entire unit is also called the secondary arm 30.
  • a gear motor 18 which can be displaced in the axial direction the holding device 11 connected.
  • this drive 18 on the drive side TS to the The winding shaft 1 is coupled and the drive 6 in the primary arm 3 is disengaged.
  • the Secondary arm 30 the horizontal nip force (contact force between Drum 1 and idler 4) via a hydraulic cylinder 19 on the driver's side FS and drive side TS generated and via the force measuring devices regulated.
  • Primary arm 3 prepared the next winding shaft 1. Once the paper wrap has reached the desired size, it is supported by the carrying drum 4 pulled away, the new winding shaft 1 in the primary arm 3 in the winding position placed on the carrying drum 4 and the full paper web P taken over. After ejecting the finished paper roll from the Secondary arm 30 moves back to carrier drum 4 and takes over then the new winding shaft 1 from the primary arm 3.
  • the force measuring devices 16 are designed in such a way that they only apply those actually applied Horizontal forces in the nip between drum 1 and carrier drum 4 to capture. Vertical components from the drives or from the changed The weight of the paper roll affects the measured values Not.
  • the measured value signals control the movement of the two Hydraulic cylinder 19, so that it is ensured that an absolute parallel operation of the secondary arms 30 on the driver's side FS and drive side TS and a Preselected nip force curve (constant or variable) over the entire Winding process is secured.
  • the sliding part 17 of the secondary arm 30 is mounted on horizontally running support rollers 21, also here to keep the influences of friction low.
  • FIG. 3 now shows a detail from FIG. 1, which represents the secondary arm 30.
  • One can here the support roller 4 and winding shaft 1 with one Detect partially wrapped paper wraps.
