Definitions

  • the invention relates to a method for producing Rolls of paper from a paper web, in which the paper web calendered and cut lengthways in partial webs will and the partial webs too. wound up the paper rolls become.
  • the invention further relates to a device for the production of paper rolls with a paper machine, a calender, a slitter and a roll winder.
  • the paper web that is usually with a width of up to 10 m is available on manageable Cut and cut widths in the range of 0.5 to 3.8 m Rolls of paper that have a diameter in the range from 0.5 to 2.5 m. Only such rolls of paper are later for a user, for example one Print shop manageable.
  • the invention has for its object the manufacture of paper rolls to simplify.
  • This task is carried out in a method of the aforementioned Kind of solved by calendering, Slitting and winding on-line without intermediate winding he follows.
  • This narrow stripe will, however not yet wound up, but in a disposal facility passed, for example a pulper.
  • This narrow strip stabilizes it is widened until it reaches the width of the paper web has reached.
  • the wide paper web will also be on Output of the winding device still disposed of. Only, when the full width paper web is in the winder the longitudinal cutting device becomes active and creates partial webs. Also the beginning of the partial lanes can still be disposed of. Only when have stabilized the partial webs, they will be on the Transfer cores transferred.
  • the partial webs immediately crosswise before transferring to the winding tubes get cut. So that on all winding cores basically wound the same web lengths.
  • the Wrapping process can be done for all paper rolls at the same time kick off.
  • the winding tubes before Transfer to path speed to be accelerated. If the partial webs cut from the paper web then come into contact with the winding tubes they attach to it with no major problems because no more relative speed between the partial webs and the winding cores prevail.
  • the paper rolls are preferably placed in a changing bed wound with a first and a second carrier roller, the paper web in contact with the first support roller runs in and the winding tubes during acceleration in Contact with the second idler roller that is driven will, and be kept at a distance from the first support roller. So you are able to control the speed the winding roller the second carrier roller to the same peripheral speed as the first Bring carrier roller.
  • the first carrier roller is otherwise also driven, their drive from the Drive of the second support roller is independent. You use so the two support rollers for different purposes.
  • the first carrier roller picks up the incoming paper web and transports them to the disposal facility, whereby the paper web if necessary with the help of a pinch roller is held on the first support roller.
  • the second Carrier roller is used to accelerate the winding tubes. If the partial webs on the winding tubes have been transferred, then take the two support rollers back to their traditional task and support the forming paper rolls.
  • both changing beds have a carrier roller in common, whereby the finished Paper roll lifts off this carrier roller and on the other Carrier roll of the changing bed runs out while the paper rolls are wrapped in the other changing bed.
  • the course of the paper web in kept essentially the same regardless of in which changing bed the paper rolls are wound.
  • you can use the speed control the first carrier roller always achieve this runs at the same peripheral speed, with which runs towards the paper web. Since you have the finished paper rolls takes off from this first carrier roller and opens it up of the second carrier roller, it is also possible the first support roller for winding the next one Throws of paper rolls to use without this the finished paper rolls is hindered.
  • the spatial Assignment of the two changing beds in close proximity to each other does not constitute a reason for the interruption of the winding process, so that the paper web still processed at the same speed can be how it comes out of the paper machine.
  • the invention is based on a device mentioned type in that the paper machine, the calender, the slitter and the roll winder in a continuous paper path are arranged one behind the other.
  • a movable one behind the calender Cutting device arranged.
  • This cutter is used from the paper web that the calender has passed through in full width, a narrow one Cut strips, which are then in the winder can be introduced.
  • the remaining part of the Paper web can be disposed of. For example, he can be fed to a pulper, the rest of the paper web recycled and in the form of pulp from the paper machine supplies.
  • the insertion of a narrow paper web strip in the winding device is much easier than introducing a wide paper web.
  • the longitudinal cutting device preferably has knives on that can be moved apart by an opening mechanism are and in a disassembled state one Release the entry path.
  • the spreading of knives a slitter is known per se. It is practiced to determine the position of the rip knife to change. In the present embodiment however, the distance between the knives is chosen so large that the paper web can be passed through without being damaged. Damage is on and not critical in itself, because the paper web is only cut Condition is wound up so that the knife must have moved here. damage the paper web could lead to web breaks, however are undesirable.
  • the movable cutting device is preferably and the opening mechanism can be locked against each other. So it is not possible to use the knife of the slitter to move together as long as the movable Cutting device not yet full of paper Cut width. This prevents uncontrollable States occur in which the beginning of a partial web may not enter the winding device correctly arrives.
  • a cross cutting device is arranged. So long the paper web or the ones cut from it Partial webs are not yet available in a windable form, they are directed to the disposal path, the for example, have a pulper of the paper machine can. Windable partial webs are in any case not before if the narrow strip in the roll winder is transferred. Even in the period where the movable cutting device on the paper web Cuts wide, the disposal path in the winding facility needed and until the Longitudinal cutting device has come into action.
  • the winding device preferably has two winding beds on who have a carrier roller in common, whereby an ejector is controllable so that it the finished paper rolls from the common carrier roller takes off and runs out on the other carrier roller.
  • the ejection device can be relatively simple be formed and have an ejection roller, so that the finished paper rolls on the second carrier roller can still rotate, this rotational movement then is braked. Once the paper rolls to a standstill have come, they will continue to be expelled and then on suitable devices, for example one Trough or a conveyor belt, from the winding device removed.
  • auxiliary device in each changing bed arranged that a set of winding tubes for pre-accelerating at a distance from the common carrier roller and in System on the other support roller stops. You can use the winding sleeves so accelerate in one changing bed, while the paper rolls are wrapped in the other changing bed become.
  • the common support roller rotate at the desired full speed, because the winding cores with it or the one running over it Paper web does not come into contact. The acceleration is rather caused by the second support roller.
  • Fig. 1 shows a device in a schematic representation for making paper rolls 3 that ultimately in a winding device 1 from a paper web 2 can be wrapped.
  • the paper web 2 is in itself known manner in a only shown schematically
  • Paper machine 100 is produced and then in a calender 200 calendered. In the direction of the web behind the calender the paper web 2 passes through a slitter, in which they are parallel to each other in several lying partial webs is cut. The partial lanes are then wound onto the paper rolls 3. Because it 1 is a schematic representation, is just the face of the foremost paper roll 3 recognizable. In fact, in Several paper rolls 3 wound one behind the other in the axial direction, a so-called litter.
  • the paper rolls 3 are two changing beds 7, 7 'provided in the winding device 1, of which the right changing bed 7 is formed by a first Carrier roller 5 and a second carrier roller 6, while the left changing bed 7 'is formed by the same first one Carrier roller 5 and a further second carrier roller 6 '.
  • the winding device 1 is with further details shown in Fig. 2.
  • a disposal device 16 is behind the winding device 1 arranged.
  • a cross cutting device 20 is arranged in front of the disposal facility 16, which is designed, for example, as a pulper can be.
  • the cross cutting device 20 can be behind the winding device 1, but also in the winding device 1 be arranged.
  • the pulper is connected to the paper machine via a line 21 connected so that it is possible to cut paper web sections, which are not rewound, again the paper production supply.
  • the paper web 2 in conventional and known per se through the calender 200 directed, for example, that one cuts narrow strips at the edge of the paper web, this strip with guide means, not shown, like ropes or the like, through the calender passes. If the narrow strip through the calender the paper web is cut to width and then runs through the calender 200 with full Width.
  • the displaceable cutting device 300 narrow strip cut from paper web 2.
  • the remaining remainder of the paper web will be in another Disposal device 22 directed, also as Pulper can be formed. That narrow strip is now passed through the slitter 4, their upper and lower knives apart for this purpose be driven so far that even with one easily vibrating paper web there is no danger that the paper web comes into contact with the knives.
  • the slitter 4 more precisely said their opening mechanism, and the relocatable Cutting device 300 provided a lock, so that the displaceable cutting device 300 can only be moved when the slitter 4 is open.
  • the strip is then with not shown, but known means, such as ropes or other guidance devices, via the first Carrier roller 5 passed into the winding bed 7 and from there led into the disposal facility 16, as is also the case can be seen schematically in Fig. 2g.
  • the displaceable cutting device 300 Move transversely to the running direction of the paper web 2, see above that the narrow strip extends to the width of the Paper web enlarged.
  • the paper web by a clamping nip between an ejection roller 10 and the first support roller 5 held and pulled. All Carrier rollers 5, 6, 6 'are driven, the drives of the two second support rollers 6, 6 'independently from each other and independently of the drive of the first carrier roller 5 can be controlled.
  • the longitudinal cutting device 4 in action, i.e. the knives are moved together again, so that the paper web 2 is cut into partial webs becomes.
  • the cross cutting device 20 operates and cuts through the partial webs at the same time total paper web width. Other separation options are basically also possible.
  • the beginning of the partial web is transferred to winding cores, which are already in the changing bed 7. On these winding cores will then be the roll of paper rolls 3 wound up.
  • suction tapes 31-34 For guiding the paper web 2 between the calender 200 and the winding device are schematic guide devices 31-34 shown, formed by suction tapes can be, as for example from the company Fibron are distributed. These guide bands are able to run the paper web 2 even at higher speeds to lead reliably.
  • Fig. 2 shows the winding device 1 for winding the Paper web 2 for a so-called throw of paper web rolls 3, which results from the fact that the paper web 2 passes through the slitter 4 in which it is cut into several partial webs.
  • the arrows in the rollers and rollers indicate which parts are rotating.
  • Fig. 2a shows a state in which the paper web rolls 3 are almost finished.
  • the paper web rolls 3 lie in the first changing bed 7.
  • each winding bed 7, 7 ' there is an auxiliary device 11, 11 'arranged with a support roller 12, 12'. How from a comparison of FIG. 2a with FIG. 2b can be seen the support roller 12, 12 'in the winding bed 7, 7' be moved vertically up and down. If you like in the left half of Fig. 2a is shown, upwards has been moved, then it holds the winding tubes 13 so that the winding sleeves 13 rest on the second support roller 6 ', but keep a distance from the first support roller 5.
  • the winding sleeves 13 in the other winding bed 7 are pre-accelerated, by the second support roller 6 'of this winding bed 7 'is set in rotation.
  • the load roller 8 'of this changing bed 7' is lowered and clamps the winding tubes together with the second carrier roller 6 'and the backup roller 12'. Possibly the loading roller 8 'can also be driven.
  • winding tubes 13 have the same peripheral speed like the first support roller 5, then lowered them into the winding bed 7 'by the backup roller 12 'is lowered.
  • the winding tubes 13 then come in contact with the incoming paper web 2 and of the second support roller 6 'of the second winding bed 7'. This situation is shown in Fig. 2b.
  • the load roller 8 ' presses the winding sleeves 13 into the winding bed 7 '.
  • the winding tubes 13 and the paper web 2 have the same speed.
  • the discharge roller 10 is lowered and, based on the Alignments in Fig. 2d, shifted to the right and until the throw of paper web rolls 3 from the first support roller 5 has been lifted off and only still on the second support roller 6 of the first winding bed 7 rests.
  • the axes of the second carrier roller form here 6, the loading roller 8 and the ejection roller 10 Triangle in which the axis of the paper web rolls 3 located.
  • the paper web rolls 3 are thus between three rollers 6, 8, 10 clamped and can thus be relative stable in position on the second carrier roller 6 are held. If necessary, this is the loading roller 8 also by a small distance shifted to the right.
  • the second support roller 6 braked. It is - and therefore also the single reel throw the paper web rolls 3 - come to a standstill, so the throw is launched in a known way. He arrives on the storage tray 9 and is from there by means of a conveyor belt, not shown axially moved out of the winding device 1.
  • FIG. 2a-2f has been sketched how the processes shape themselves if continuous single roles with constant dimensions are to be produced.
  • Fig. 2g shows in addition how to proceed to change a format, i.e. the width of the from the paper web 2 cut with the help of the longitudinal cutting device 4 Partial webs.
  • the paper web 2 is made in a known manner cut across.
  • the discharge roller 10 now gets one additional function. It is on the first carrier roller 5 lowered and then forms with the first support roller 5 a clamping nip through which the incoming paper web 2 is further promoted.
  • the paper web will, however no longer wound up, but passes through it Changing bed 7 in the disposal device 16, for example the pulper of a paper mill. If further running paper web 2 then the upper and lower knives the slitter 4 at a distance from each other brought, the slitting is interrupted, so that the upper and lower knives are known per se Can be repositioned. Is this happen, the slitting process is resumed. As soon as the single tracks created the Nip between the ejection roller 10 and the first support roller 5 have passed, they are across the width of the paper web 2 separated and the new starts wound on corresponding empty tubes 13.
  • winding tubes For inserting the winding tubes into the winding beds 7, 7 ' it may be appropriate to place the winding tubes on winding rods thread or otherwise axially fix. Basically you can use the empty winding tubes 13 but also on slides or sliding levels in the winding beds Insert 7, 7 '.
