Definitions

  • the invention relates to a method for winding Partial webs to partial web rolls that are axially offset from each other in several winding position groups at different Circumferential positions at a common Central roller in contact with the partial webs when reached a predetermined diameter of the partial web rolls cut and handed over to new roll cores become.
  • the invention is intended to be based on a paper web can be described as an example of a material web. However, you are not limited to this. Similar problems arise when cutting paper-like products, such as cardboard, or of plastic films or Metal.
  • Paper webs are often used today on paper machines produced, whose working width is larger than that of Users, such as printers, desired Width. For this reason, the paper webs must be in one of the last manufacturing steps to the corresponding one Cut width and then rolled up or be wound up. At least this always arises two, but usually more, part web rolls. There are two for winding these partial web rolls known various possibilities. For one, can all partial web rolls axially next to each other in a common Changing bed can be wrapped by two or more support rollers is formed. This winding takes place So according to the roller principle.
  • Another principle is the so-called backup roller principle, in which the individual partial web rolls on their roll core being held. To adjust the winding hardness, which among other things by the contact pressure during winding is determined, the partial web rolls are on one Pressure roller on. If you have this pressure roller for everyone Partial web rolls used together, one speaks also from a central roller.
  • the invention has for its object the role change when winding in different winding position groups to simplify.
  • This task is carried out in a method of the aforementioned Kind solved in that the partial webs in the contact area of the partial web rolls with the central roller get cut.
  • the partial webs of different winding position groups are advantageous cut one after the other. This has the advantage that the individual partial webs in the winding position groups that are not currently transferred either through the finished web rolls be fixed or by the fact that the partial web starts are already fixed to the new roll cores. Naturally other holding options are also conceivable. Man can, however, rely on this procedure Cutting the partial webs in a winding position group focus without fear of interference occur due to partial webs of other winding position groups.
  • the beginning of the partial webs is preferably started the central roller and the cutting device before connecting the web starts with roll cores brought back to a starting position.
  • This has the advantage that for everyone Cutting operations have the same initial conditions. Above all, this has the advantage that the cutting device always cut the partial webs right there can where the partial webs are lifted from the central roller are to be wound up on the partial web rolls. In any case, the cutting device can be radial outside of the partial webs lying on the central roller being held.
  • the beginning of the web starts the central roller. So there is one Holding facility available that the movement of the Cutting device not hindered.
  • the suction is a relatively gentle holding process, so that even sensitive Material webs are treated in this way can.
  • the cutting device is advantageously used for transport of partial web beginnings used. This is cheap if the partial webs are not made of an endless material web be cut, but for example by one finite jumbo or parent roll, which is occasional must be changed. This arises from time to time Time the problem that partial train starts around the Back-up roller is conveyed around to the last winding position group Need to become. This problem can be solved without Solve further construction effort when the beginnings of the partial webs held by the cutting device that can be around the central roller anyway or together with her in the last winding position group must be able to be pivoted.
  • the partial web starts can therefore differ from the central roller solve and fall, usually under the effect gravity, back. If more than two Winding position groups are provided, then remain Partial webs representing the middle winding position groups (i.e. between the first and the last winding position group located) held there or get stuck there. On the way back to their starting position the cutting device can then all Partial webs in the area of their winding position groups cut and thus automatically to the correct length bring.
  • a train interruption by the partial lanes be sucked to the surface of the central roller.
  • This frictional engagement enables that the necessary for cutting the partial webs Tension is applied.
  • Behind the section, at which the partial webs to the surface of the central roller are sucked in the partial webs are practically without tension to disposal.
  • the winding tension can then set by driving the individual web rolls become.
  • the winding tension is therefore of the Voltage decouples that for cutting the partial webs necessary is.
  • this configuration another advantage. Especially very smooth papers, for example, SC papers and coated papers problematic in terms of the maximum winding speed. With increasing speed the negative influence of the incoming air on the material web attached.
  • the central roller will be sucked in for this ensured that the incoming air is immediately removed will, i.e. a floating of the partial webs and thus a running of the partial webs in the transverse direction is prevented.
  • the partial webs are very simple fixed on the roller surface.
  • the invention also relates to a winding device for Winding of partial webs to partial web rolls, which in at least two winding position groups in different Circumferential positions axially offset from one another common central roller in which the above Object is achieved in that a cutting device, which extends axially across all winding positions extends around the center roll through all winding position groups is pivotable.
  • the cutting device is preferably provided with a holding device combined with the at least one partial web can be fixed on the surface of the central roller is. So with the cutting device it is at the beginning a winding process in which all partial web starts have the same length, possible, the one or more To register partial web starts and around the central roller around to the assigned winding position group respectively. There are no other holding devices necessary. In particular, this excludes that the holding device and the cutting device collide with each other.
  • the cutting device preferably acts in both circumferential directions.
  • a cutting direction that is parallel to the Direction with which the partial webs around the Central roller run around. With this cutting direction the partial webs are cut where they meet the central roller leave, that is, at the transition from the edition on the central roller to rest on the partial web rolls.
  • it can be advantageous to all partial web beginnings to the last winding position group for example by holding with the cutter. There will be only the partial web beginnings assigned to this winding position group fixed. All other starts of the sub-track fall back. If now the cutter backwards is moved, it can be in the other cutting direction act and the partial webs also in their individual Cut winding position groups.
  • the central roller advantageously has for each winding position group one with a holding force Stopping area.
  • This stop area is used for preparation of winding, i.e. to hold the beginning of the partial web until the individual roll cores are in position brought and connected to the beginning of the subway are. As long as the partial web starts, for example after the cutting device can be held there moved back to their starting position become.
  • the holding areas can preferably be subjected to negative pressure. Sucking the beginning of the partial web to the The surface of the central roller is a relatively simple one and gentle possibility of the partial webs on the central roller to hold on. In addition, this configuration the advantage that the necessary for holding Do not collide with the cutting device.
  • a slitter winder 1 has a feed section 2 in which a material web 3, for example a paper web unwound from a jumbo or parent roll, is fed.
  • the material web 3 passes through then a cutting section 4 in which they pass through themselves known means, for example cutting knives 5, 6 in Partial webs 7 is divided.
  • the cutting knives 5, 6 cut the material web 3 in the longitudinal direction. A certain pulling force is required for this.
  • This Traction is applied via a central roller 8, the is designed as a suction roll.
  • the central roller 8 has a roller shell 9, the shown for the sake of clarity is. There are many bores or holes in the roll shell 9 10 arranged, which enforce the roll shell 9. in the Inside the roll shell 9 is a first suction chamber 11 and a second suction chamber 12 arranged over a Suction port 13 can be supplied with negative pressure. With in other words, air from the suction chambers becomes permanent 11, 12 suctioned off.
  • the two suction chambers 11, 12 extend in the circumferential direction each only over a part of the Central roller 8.
  • the suction chamber 11 points in the circumferential direction two boundary walls 14, 15.
  • the suction chamber 12 has boundary walls 16, 17. All boundary walls 14-17 are about not shown Sealant sealed on the inner circumference of the roll shell 9.
  • Both suction chambers 11, 12 extend over angular ranges in the order of 60 °. This angle is however not mandatory. You can also get bigger or smaller ones choose an angle, especially for the suction chamber 11 ensures that the suction pressure in the Suction chamber 11 together with the surface of the central roller 8, which is determined by the angle, is sufficient around the partial webs 7 so strongly against the surface of the To press central roller 8 that the resulting Friction is sufficient to cut the necessary Transfer traction.
  • Partial web rolls 18, 19 of adjacent partial webs are in different winding position groups 20, 21 arranged.
  • the individual partial webs 18, 19 have one certain axial distance from each other, can otherwise but the same or approximately the same Have winding axis.
  • the partial web rolls 18, 19 of the two Winding position groups 20, 21 are on each other Gap arranged.
  • the partial web rolls 18, 19 are on roll cores 21, 22 wound, which are driven, for example by retractable mandrels, which in turn have a drive. This is only schematic indicated in the figure.
  • the roll cores are on the one hand in one Position shown in which the partial web rolls 18, 19th have already reached a certain extent. they are (for the purpose of distinguishing without drive) on the other hand drawn in a position in which the Winding of the partial web rolls 18, 19 just begins.
  • the present Embodiment assumed that the centers or axes of rotation of the central roller 8 and the roller cores 21, 22 and thus the partial web rollers 18, 19 a horizontal plane 24 are arranged.
  • the centers the roll cores 22, 23 move when Wrap horizontally in this plane 24. It is accordingly also the point of contact between the partial web rolls 18, 19 (or at the start of winding between the roll cores 22, 23) arranged in this plane 24. This are then also the places where the partial webs Leave central roller 8.
  • the suction chamber 11 now ends somewhat in the circumferential direction before this level 24, i.e. the lower boundary wall 14 forms an angle 25 with the plane 24, which however can be relatively small, for example in the Order of magnitude in the range of 1 ° to 10 °. This ensures that the vacuum in the Suction chamber 11 can no longer act on the partial web, if it is to be lifted off the central roller 8, to be wound up on the web roll 19. Of the Suction section formed by the suction chamber 11 ends at the location where the partial webs 7 be lifted off the central roller 8.
  • the suction chamber 12 can over the Extend location where the partial webs 7 removed be wound up on the web rolls 18 become.
  • the reason for this is that the Suction chamber 12 is used exclusively for the partial webs, which are wound onto the partial web rolls 18, to hold on to the central roller 8 until they on the or the roll cores 22 arrive where they are stuck during the set-up become.
  • the suction chamber 11 can also be used for this purpose become.
  • the negative pressure in the suction chamber 11 adjustable to different values. In operation, so when winding, it must be set so high that the frictional engagement between the partial webs 7 and the central roller 8 is sufficient to cut the necessary To apply tension. This is not the case when setting up necessary. It is enough here, the beginnings of the partial lanes to lead to the roll cores 23. It ends the suction chamber 11 before the corresponding contact point. However, this is not critical because the partial webs 7 here be fed from above. So you hang out after that Leaving the suction section freely and down with the help of gravity, so to speak, their roll cores 23 forwarded.
  • the central roller 8 has an axis 30 around which a carrier 31 in the direction of its two axial end faces a double arrow 32 is pivotable.
  • the carrier 31 is slightly above the diameter of the central roller 8 over.
  • one Cutting device 33 arranged which is a narrow knife 34 has that in the axial direction between the two Carriers 31 is excited. Because of the axial tension the knife has a relatively high stability. It has a cutting edge on each of its two edges 35, 36 so that the knife 34 in both directions can cut.
  • the knife 34 is also movable in the radial direction below Effect of a schematically represented drive 37, for example a pneumatic or hydraulic Piston-cylinder arrangement. This is made possible Movement of the knife 34 by a likewise schematic shown elongated bearing opening 38 for the Knife 34 in carrier 31.
  • a schematically represented drive 37 for example a pneumatic or hydraulic Piston-cylinder arrangement. This is made possible Movement of the knife 34 by a likewise schematic shown elongated bearing opening 38 for the Knife 34 in carrier 31.
  • the first example assumes that in the two Winding position groups 20, 21 partial web rolls 18, 19 see above have been widely wound that their target diameter has been achieved.
  • the winding is interrupted.
  • the Cutting device 33 moves from the starting position shown clockwise around the central roller 8 around. In doing so, it first cuts through the partial webs, which wound up in the winding position group 21 become. As the negative pressure is maintained in the suction chamber 11 the corresponding partial webs remain fixed here.
  • the cutting device 33 is further around the central roller 8 swung around and then severed after one Swivel angle of slightly more than 180 ° also the partial webs, which are wound in the winding position group 20. Since the suction chamber 12 is also subjected to negative pressure the beginnings of the partial lanes remain the cutting fixed on the surface of the central roller 8. The cutting device 33 can then be shown in the Starting position can be retracted. New Roll cores, for example with a self-adhesive Can be provided on the surface Partial beginnings approached and the beginnings of the partial lanes then attached. The negative pressure in the suction chamber 12 can be switched off. The negative pressure in the Suction chamber 11 can be used for a train interruption sufficient value. After that you can start winding the partial web rolls 18, 19 again. The role change is relatively quick because of it it is no longer necessary to lengthen the individual partial webs to the different distances between the cutting section 4 and the individual winding position groups 20, 21 to adapt.
  • This operational flow applies when from an endless Material web 3 or a material web 3 with a much greater length than on the partial web rolls 18, 19 is wound up, several partial web rolls 18, 19 are wound.
  • a new material web 3 is used overall, for example when a new jumbo or mother role the operating procedure is slightly different.

  • the partial webs are now on the surface of the central roller 8 clamped.
  • the Cutting device 33 then rotates together with the Central roller 8 until all partial web starts in the winding position group 20 have arrived. There will now the suction chamber 12 is put into operation so that all Partial beginnings are held there.
  • the roll cores for the partial web rolls 18, which in the Winding position group 20 are then wound connected to the corresponding partial web beginnings.
  • the Knife 34 has meanwhile been detached from the partial webs been and a bit counterclockwise pulled back. If now the vacuum in the suction chamber 12 is switched off, the fixation of the Partial beginnings for the partial webs that are not in the Winding position group 20 to be wound. This then fall down under the action of gravity, So slip out of the gap between the knife 34 and the central roller 8 out. In the illustrated Embodiment then hang these partial webs vertically in the area of the nip of the winding position group 21 downward. If the cutting device 33 is driven back, then it cuts through the hanging ones Partial webs 7 exactly in this area. Possibly you can still ensure that the partial webs are a little tense here.
  • the second cutting edge 36 occurs during this cutting in action.
  • Knife 34 is usually thin enough to pass through the nip between the partial web rollers 18, 19 and the central roller 8 to be led. If the extension in Circumferential direction is small enough, then it is not necessary to provide the knife 34 with a curvature. Since you normally have a relatively thin tape, the can be clamped well when knife 34 is used this band when going through the respective nips adjust the curvatures required, if this is necessary.
