Definitions

  • the invention relates to a method for winding at least two side by side moving material webs, in particular paper or board webs, on at least two in one of two support rollers formed winding bobbin stacked winding cores to at least two bobbins, said at least two material webs by means of at least one, the Winding bed in the direction of a preferably machine-width material web upstream longitudinal cutting device are cut from the same.
  • the invention relates both to a winding tube for use in the method according to the invention and a winding machine for carrying out the method according to the invention.
  • Carrier roll winding machines are used to wind up material partial webs, in particular paper or cardboard webs, to wound reels.
  • the carrier roll winding machines in this case have a first and a second support roller, which lie side by side and form a winding bed for receiving cores, on which the material webs are wound side by side.
  • the material partial webs are usually produced from a single, wound on a Volltambour and preferably machine-width material web by the wound on the Volltambour and preferably machine-width web passes during unwinding longitudinal cutting devices for generating the material webs. The material webs produced are then impact on the in the winding bed wound up next to each other.
  • the elongation of the cores is for example 1 per thousand of their length. Since all adjacent cores are "fixed” by the chucks in their position, so can not expand freely, large axial forces arise in the cores. These forces lead to the offset of the sleeve centers to each other, whereby the smoothness during winding is significantly disturbed. It can come to a "swinging" of the bobbins, which forces the operator of the carrier roll winding machine to a reduction in the winding speed.
  • a very disadvantageous effect is that the adjacent winding rolls are not centrally fixed. They therefore do not rotate cylindrically in a row, but offset in the middle, resulting in non-centric sitting cores. The corresponding bobbins then run in the settlement of printing machines out of round, which is unacceptable.
  • the adjacent winding cores are provided at the end with corresponding contours, wherein the contours are kept at a distance.
  • the distance between the corresponding contours allows an elongation of the cores, without causing significant shifts of the winding rollers in the winding bed.
  • the invention is therefore the object of developing a method of the type mentioned in such a way that disturbances in the winding of the winding rolls and in the further processing of the winding rolls are avoided.
  • a winding tube for use in the method according to the invention and a winding machine for carrying out the method according to the invention are to be specified.
  • the web is wound uncut in their initial layers on the bumps adjacent bobbins.
  • the initial layers of the material web are the layers which are wound up on the same after the first winding of the cores.
  • the invention is thus characterized by the creation of a machine-wide "sleeve", which prevents the wrapped therein cores from moving radially against each other. So there is no offset of the sleeve centers to each other, whereby the smooth running during winding could be significantly disturbed.
  • the previously known “commuting" the bobbins with its disadvantages and effects described is thus effectively avoided.
  • the winding machine can be operated at significantly higher winding speeds, which in turn increases the runnability and productivity of the winding machine.
  • the inventive solution has another, not to be underestimated advantage:
  • the initial layers of the material web can be described according to the invention by means of various embodiments.
  • the material web can preferably be unwound wound on the cores in a layer region of 2 to 50 layers, preferably from 5 to 35 layers, in particular from 10 to 25 layers. Furthermore, it can be wound uncut on the cores in a length range of 0.5 to 10 m, preferably from 1 to 8 m, in particular from 2 to 5 m. Or it can in a time range of 1 to 12 s, preferably from 2 to 10 s, in particular from 3 to 8 s uncut on the cores be wound up. All three described embodiments are characterized by the creation of a machine-wide "sleeve", which meets the operational requirements for stiffness, pendulum avoidance of the cores, superordinate smoothness and the like fully fair.
  • the at least one longitudinal cutting device is preferably activated with a time offset to the beginning of winding of the material web on the at least two cores in order to subsequently cut the at least two partial material webs.
  • the activation is preferably carried out by the employment of at least one cutting blade of the corresponding longitudinal cutting device in the moving material web.
  • the initial layers of the uncut material web are separated during the ejection of the finished wound roll.
  • the separation of the initial layers of the uncut material web can necessarily take place; in a further embodiment, it can also be separated by means of at least one auxiliary cutting device at the same time, approximately at the same time or with a time offset.
  • the winding tube according to the invention for use in a method according to the invention is characterized in that in the region in which it abuts against an adjacent winding tube, it has an annular surface which is perpendicular or approximately perpendicular to its center line.
  • an advantageous embodiment may consist in that the winding tube in the region in which it abuts on an adjacent winding tube, a centering element which forms a positive connection with a centering of the adjacent winding tube at least in the axial direction.
  • the winding machine according to the invention for carrying out the method according to the invention is characterized in that the at least one longitudinal cutting device can be activated with a time shift to the beginning of the winding of the material web on the at least two cores, in order to then cut the at least two partial material webs.
  • the at least one longitudinal cutting device can be activated with a time shift to the beginning of the winding of the material web on the at least two cores, in order to then cut the at least two partial material webs.
  • the winding machine 1 shows a schematic side view of a winding machine 1 together with upstream longitudinal cutting device 2.
  • the winding machine 1 is designed as a (double) carrier roll winding machine, as described for example in the German utility model DE 200 13 319 U1 and the European Patent EP 0 792 245 B1 is described.
  • the winding machine 1 shown serves for winding a plurality of juxtaposed material part webs 3, in particular paper or board webs, on several in one of two mutually parallel support rollers 4, 5 winding bed 6 stacked adjacent to each other winding tubes 7 to bobbins 8.
  • the bobbins 8 are during the winding of the material webs 3 on the support rollers 4, 5 in the formation of two respective nips N4, N5.
  • the winding bed 6 in the direction L (arrow) of a preferably machine-wide web 9 upstream slitter 2 is provided which intersects the material webs 3 from the web 9.
  • the partial material webs 9 are then guided laterally around the jacket of one of the two support rollers 4, 5 or through the gap formed between the two support rollers 4, 5 in the winding bed 6, where they are wound onto the aligned winding cores 7 to 8 bobbins.
  • the material part webs 3 are guided around the inner shell of the driven support roller 4 and then passed through the winding bed 6, before they are wound up.
  • the illustrated longitudinal cutting device 2 for cutting the preferably machine-width material web 9 in material partial webs 3 has a pair of knives 10, which comprises a knife web 11 supporting the material web 9 during cutting (bottom knife) and a knife 12 (upper knife) dipping into the material web 9.
  • the cutting edges of the two blades 11, 12 must be positioned exactly to each other in the desired cutting position.
  • a lower blade 11 driven pot knives and as a top blade 12 disc-shaped and freely rotatable pointed blades are used as For example, in the German patent DE 34 19 843 C2 are described.
  • the two knives 11, 12 are arranged on a respective carriage 13, 14, which are adjustably mounted on each one transverse to the direction L (arrow) of the web 9 extending blade crossbar 15, 16 and each having a knife holder 17, 18 for storage and preferred movement of the associated blade 11, 12 have.
  • Each knife 11, 12 can be positioned transversely to the running direction L (arrow) of the material web 9 to be cut in order to set the required format width.
  • each upper blade 12 in the direction of its axis of rotation against the associated lower blade 11 can be adjusted so that the two cutting edges can be aligned exactly relative to each other.
  • the blades 11, 12 may of course be mounted on a common carriage.
  • the movement-causing components such as the knife holder 17, 18 of the moving longitudinal cutting device are connected in a manner known in the art with a merely schematically indicated control / regulating unit 19, which takes over the control / regulation of the method for longitudinal cutting of the material web 9.
  • the control unit 19 can in turn be connected to a higher-level process control system (PLS).
  • FIG. 2A and 3A show a respective schematic side view of a winding machine 1. Since the structure of these winding machines 1 basically corresponds to that of the winding machine 1 shown in detail and described in detail in FIG. 1, reference is made at this point to its description of figures.
  • Figures 2B and 3B show a respective schematic plan view of bobbins 8 made with the prior art winding machines 1 shown in Figures 2a and 3A.
  • each winding tube 7 made of cardboard undergoes an elongation as a result of the layer pressing of the wound on it Material part web 3 and under the additional load of a possible, known in the art pressure roller which presses from above onto the winding roller 8.
  • the elongation of the winding tube 7 is, for example, 1 per mille of its original length of, for example, 2,000 mm, then the wound winding tube 7 has a length A of 2,002 mm.
  • This elongation causes the already described and in the two figures 2b and 3B respectively illustrated offset of the sleeve centers to each other, whereby the smoothness during winding is significantly disturbed. For example, FIG.
  • FIG. 2B shows an alternating offset of the sleeve centers with a deviation B of 53 mm under the given conditions
  • FIG. 3B shows a displacement of the sleeve centers along a curved line D having a deviation C of 190 mm.
  • FIG. 4 shows a schematic sectional view through three winding rolls 8, which were prepared using the method according to the invention.
  • the material web 9 is uncut wound in their initial layers E on the stacked adjacent winding tubes 7. From the presentation of other components and groups of the winding machine was omitted for clarity.
  • the initial layers E of the material web 9 can be described according to the invention by means of various embodiments.
  • the material web 9 in a layer region of 2 to 50 layers, preferably from 5 to 35 layers, in particular from 10 to 25 layers uncut on the winding tubes 7 are wound. Furthermore, it can be wound uncut on the winding tubes 7 in a length range from 0.5 to 10 m, preferably from 1 to 8 m, in particular from 2 to 5 m. Or it can be unwound wound on the winding tubes 7 in a time range of 1 to 12 s, preferably from 2 to 10 s, in particular from 3 to 8 s.
  • the cut material webs 3 are then wound in further layers F on the resulting bobbins 8.
  • the longitudinal cutting device 2 (FIG. 1) is activated with time delay at the start of winding of the material web 3 on cores 7 in order to subsequently cut the material substrains 3.
  • the activation is preferably carried out by the employment of the dipping knife 12 (upper knife) of the longitudinal cutting device 2 in the moving material web 9, wherein the activation is effected by the control / regulating unit 19.
  • Each winding tube 7 has in the region 20 in which it abuts on an adjacent winding tube 7, a perpendicular to its center line M or approximately perpendicular annular surface 21. Furthermore, it can also have an axially compressible element 22, for example a conical projection or a conical recess or depression in this region 20.
