Definitions

  • the invention relates to a method for producing Paper rolls from a paper web, in which the paper web calendered and cut longitudinally in partial webs is and wound up the partial webs to the paper rolls calendering, slitting and Winding on-line without intermediate wrapping. Further The invention relates to a device for manufacturing of paper rolls with a paper machine, a calender, a slitter and a Rollenwikkel driving, the paper machine, the calender, the slitter and the roll winder in a continuous paper web running path one behind the other are arranged.
  • the paper web which is usually with a width of up to 10 m, manageable Widths in the range of 0.5 to 3.8 m cut and closed Rolled paper rolls that have a diameter in the range from 0.5 to 2.5 m. Only such paper rolls are later for a user, for example one Print shop manageable.
  • EP 0 744 492 A shows a method and a device of the type mentioned.
  • the winding station upstream is a calender from two rolls.
  • the winding station has a support roller on, with another roller a second calender forms.
  • US 4,763,822 A describes a device for guiding a paper web.
  • the paper web is made by a dry group a paper machine through a calender with multiple rolls and a calender with two rolls too a winding up.
  • the free trains between the individual stations are bridged with bands, which are pulled over vacuum boxes.
  • louvers arranged in the places where a change in direction is required are louvers arranged.
  • US 5,943,787 A shows a web finishing section in FIG a paper machine.
  • the finishing section points two machine calendars.
  • a drum magazine is arranged above the last machine calender.
  • US 4 508 279 A describes a winding device with two winding stations. Each wrapping station has two Carrier rollers and a load roller on. The one in one Winding station coiled rolls are centric held because of the bracket on a machine frame moves upward when the diameter of the Winder rolls enlarged.
  • US 5 158 648 A describes a device to a to cut narrow strips from a paper web and this strip at a later stage of the procedure enlarge.
  • the invention is based on the object, the production to simplify paper rolls.
  • the first carrier roll Given the finished paper rolls from this first one Lifting roller lifts and they leak on the second support roller it is also possible, the first carrier roll to use for wrapping the next roll of paper rolls, without this hampered by the finished paper rolls becomes.
  • the spatial allocation of the two Wikkelbetten forms in close proximity to each other So no reason for the interruption of the winding process, so that the paper web is still the same Speed can be processed as they are comes out of the paper machine.
  • a narrow strip the paper web into a winding device and from there to a disposal facility leads, this Strip then widened to the width of the paper web, then longitudinally cuts and the longitudinally cut Sub-webs then transferred to cores.
  • This is basically all situations too understand in which the paper web is newly "threaded" must become. This not only occurs when starting the paper machine on, but also for example after one Paper web break. Inserting the paper web in the calender, the slitter and the Wikkelinnate is almost impossible in full width.
  • One therefore uses a narrow one first Strip which can be with known means, such as Cable guides or suction belts, from calender to Wikkel noticed leads.
  • This narrow strip will however not yet wound, but in a disposal facility passed, for example, a pulper.
  • this narrow strip stabilizes has, it is widened until it reaches the width of the paper web has reached.
  • the wide paper web is also on Output of the winder still disposed of. Only, when the paper web with full width in the winding device reaches, the slitter is active and generates partial webs. Also the beginning of the subways can still be disposed of. Only then, when have stabilized the partial webs, they are on the Winding tubes transferred.
  • the partial webs directly before passing on the cores transversely get cut. This will be on all cores basically the same web lengths wound up. Of the Wrapping process can be done for all paper rolls at the same time kick off.
  • the cores before the Passing on be accelerated to web speed.
  • the part webs cut from the paper web then come in contact with the cores, let they attach themselves to it without major problems, because no relative speed more between the partial webs and the winding tubes prevails.
  • the paper rolls in a winding bed wound with a first and a second carrier roll the paper web being in contact with the first carrier roll runs and the cores when accelerating in Contact with the second carrier roll driven is, and kept at a distance to the first support roller.
  • This one is able to through a speed control the second carrier roll the cores at the same peripheral speed as the first Carrying cylinder to bring.
  • the first carrier roll is otherwise also powered, their drive from the Drive the second support roller is independent.
  • the first carrier takes up the incoming paper web and transports them to the disposal facility, wherein optionally, the paper web by means of a pinch roller is held on the first support roller.
  • the second Carrier roller is used to accelerate the cores. When the partial webs on the cores have been transferred, then take the two support rollers to once again fulfill and support their traditional role the forming paper rolls.
  • the invention is in a device of the above mentioned type solved in that the winding device Has winding beds that have a support roller in common, an ejector being controllable that they are the finished paper rolls from the common Lifting roller lifts and run out on the other support roller leaves.
  • the ejection device can be relatively easily formed be and have a discharge roller, so that the finished Rotate paper rolls on the second carrier roll can, whereby this rotational movement then braked becomes.
  • appropriate Devices such as a trough or a conveyor belt, transported away from the winding device.
  • a movable Cutting device arranged behind the calender. This cutting device is used from the paper web to the calender has gone through in full width, a narrow one Strip to cut, then into the winding device can be introduced.
  • the remaining part of the Paper web can be disposed of. For example, he can fed to a pulper, which rest the paper web reprocessed and in the form of pulp of the paper machine supplies.
  • the insertion of a narrow paper web strip in the winding device is much easier as the insertion of a wide paper web.
  • the longitudinal cutting device has knives on, which can be moved apart by an opening mechanism are and in disassembled state one Release the insertion path.
  • the moving apart of knives a slitter is known per se. It is practiced to the position of the slitting knife to change.
  • the distance of the knife is chosen so large that the paper web can be driven through, without being damaged. Damage is on and uncritical in itself, because the paper web is only cut in Condition is wound up, so that the knives have to be here together. damage but the web could lead to web breaks, the are undesirable.
  • the movable cutting device and the opening mechanism locked against each other. So it is not possible, the knife of the slitter ride together as long as the movable Cutting device the paper web is not yet full Has cut width. This avoids that uncontrollable States occur in which the beginning a sub-course may not be right in the Wikkel Anlagen arrives.
  • a Disposal path arranged, taking in front of the disposal path a transverse cutting device is arranged.
  • Partial webs are not yet available in a windable form, they are directed to the disposal path, which For example, have a pulper of the paper machine can. Winding partial webs are anyway not before, when the narrow strip in the reel winder is transferred. Also in the period where the movable cutter on the paper web Width cuts, the disposal path in the Wikkel worn needed and that until the Slitter has entered into action.
  • an auxiliary device is in each winding bed arranged, which a set of winding tubes for pre-accelerating at a distance to the common support roller and in Holds attachment to the other carrier roll. You can the Wikkelhülsen so accelerate in the one winding bed, while in the other winding bed wrapped the paper rolls become.
  • the common support roller rotate at the desired full speed, because the cores with her or running over it Paper web does not come into contact. The acceleration is caused by the second support roller.

  • the paper web 2 is in itself known manner in an only schematically illustrated Paper machine 100 produced and then in a calender 200 calendered. In web direction behind the calender the paper web 2 passes through a longitudinal cutting device, in which they are in several parallel to each other lying partial webs is cut. The partial webs are then wound on the paper rolls 3. Because it FIG. 1 is a schematic representation, FIG. is only the front of the foremost paper roll 3 recognizable. Actually, though, in Axially one behind the other several paper rolls 3 wound, a so-called litter.

Of the remaining remainder of the paper web will be in another Disposal facility 22 passed, which also as Pulper can be formed. This narrow strip is now passed through the slitter 4, their upper and lower blades for this purpose apart be driven so far that even at a lightly vibrating paper web is no danger that the paper web comes into contact with the knives.
  • the longitudinal cutting device 4 more precisely said its opening mechanism, and the displaceable Cutting device 300 provided a lock, such that the displaceable cutting device 300 can only be moved when the slitter 4 is open.
  • the strip is then shown with unspecified, but known per se, such as ropes or other control devices, over the first Carrier roller 5 passed into the winding bed 7 and from there led into the disposal facility 16, as well as can be seen schematically in Fig. 2g.
  • the displaceable cutter 300 becomes moved transversely to the direction of the paper web 2, so that the narrow strip down to the width of Paper web enlarged.
  • the paper web becomes by a Klemmnip between a discharge roller 10 and the first support roller 5 held and pulled. All Carrier rollers 5, 6, 6 'are driven, the drives the two second support rollers 6, 6 'independently from each other and independently of the drive of the first support roller 5 can be controlled.
  • the cross cutter 20 is active and cuts through the partial webs simultaneously over the entire paper web width. Other separation possibilities but are also possible in principle. After or at the same time the partial web beginnings are transferred to cores, which are already in the winding bed 7. On These cores then becomes the throw of paper rolls 3 wound up.
