Definitions

  • the invention relates to a method according to the preamble of claim 1 for Continuous reeling up of a paper web.
  • EP-483092 B1 discloses a method for performing a paper reel change in such a manner that the new reeling core is brought in connection with a paper web passed by the same whereafter a change is conducted.
  • the method according to which the end of the paper web cut in the change situation of the reeling core is guided past the full paper reel in the machine direction is characterized among other things in that the paper reel formed on the reeling core is transferred in the machine direction.
  • the continuous reeling up according to the method can be implemented in such a way that the reel change threading apparatus is stationary both a the time of reel change and during the reeling.
  • the invention also relates a reel-up according to the preamble of the independent claim relating to the reel-up.
  • the reel-up which is of the type where at least part of the reel change threading apparatus is placed in such a manner that it guides the end of the paper web cut in the change situation of the reeling core past the full paper reel, is primarily characterized in that said at least part of the reel change threading apparatus is arranged to constitute the first part of the means for establishing a nip contact when the paper reel that is being formed on the reeling core is transferred in the machine direction.
  • the appended dependent claims relating to the reel-up present some preferred embodiments of the reel-up.
  • the reel-up comprises a closed supporting belt rotation 1, which has been produced by means of guiding rolls 2 placed inside the supporting belt rotation 1, via which the endless supporting belt 1 a rotates.
  • the supporting belt rotation 1 is connected to the end of the drying section 3 from which the paper web is passed on top of the supporting belt rotation 1 to be guided to the reeling up stage.
  • a reel change threading apparatus 4 Inside the supporting belt rotation 1 there is a reel change threading apparatus 4 the function of which will be described in more detail hereinbelow for the part of certain functions.
  • the ends of the reel change threading apparatus are provided with two rolls 2a, 2b which simultaneously participate in the guidance of the travel of the supporting belt rotation 1, said rolls belonging to the means for establishing nip contact, especially to the means for establishing a so-called secondary nip contact, i.e. the roll 2a constitutes a first nip member part, and the roll 2b constitutes a second hip member part. Furthermore, in the end accommodating the first nip member part 2a the supporting belt rotation 1 is provided with means for cutting the end of the paper web, i.e. a cutting device 5.
  • a cutting device 5 In the embodiment of the reel-up according to Figs.
  • the paper web rotates counterclockwise in accordance with arrow K to the reeling cores 6 to 7, first passing the reel change threading apparatus 4 on top of the supporting belt rotation 1 in the machine direction, substantially in a horizontal position and travelling away from the end of the drying section 3, and turning towards the drying section 3 at the location of the cutting device 5, thereafter continuing its travel to the reeling core 6 or 7 in question.
  • the said embodiment of the reel-up is characterized in that two sets of reeling cores - a first and a second reeling core set - are established.
  • the reference numeral 6 represents a reeling core belonging to the first reeling core set
  • the reference numeral 7 represents a reeling core belonging to the second reeling core set.
  • the reeling cores 6 and 7, which are located in the reeling up station, are placed successively on the same horizontal level in the machine direction, within a horizontal distance from each other in such a way that their central axles are parallel to each other. In the vertical direction, the central axles of the reeling cores 6 and 7 are substantially located by the first 2a and second nip member part 2a, respectively.
  • the reeling cores 6 and 7 are supported from underneath by means of nip member parts 8 and 9 (the reference numeral 8 indicating a third nip member part and the reference numeral 9 a fourth nip member part) for establishing a so-called primary nip contact, which nip member parts belong to the means for establishing a nip contact.
  • nip member parts 8 and 9 the reference numeral 8 indicating a third nip member part and the reference numeral 9 a fourth nip member part
  • the first 2a and the second 2b nip member part are thus intended for establishing a so-called secondary nip contact to ensure the quality of the paper reel that is being formed, e.g. to prevent the access of air between the paper layers.
  • the third 8 and the fourth nip member part 9 are intended for establishing a so-called primary nip contact, i.e. to control the formation of the paper reel.
  • the nip member parts 8, 9 establishing the first or primary nip contact are located below the central axle of the reeling core 6, 7 of the paper reel that is being formed, and the nip member parts 2a, 2b establishing the second or secondary nip contact, as well as said at least part of the reel change threading apparatus 4, are placed above the fulcrum of the reeling core 6,7 of the paper reel that is being formed.
  • Fig. 1 a shows a situation in which the filling of the reeling core 6 (reel RA) belonging to the first reeling core set is started after the reeling core 7 belonging to the second reeling core set has become full, by guiding the end of the paper web cut by means of the cutting device 5 directly to the reeling core 6.
  • the reeling up process to the reeling core 6 has proceeded so far that the preceding full paper reel has been removed and a new reeling core 7 belonging to the second reeling core set has been brought to the change station.
  • the fulcrum of the reeling cores 6 and 7 remains substantially stationary with respect to the machine frame during the reeling up process, and the third nip member part 8 is transferred downward in the direction of the arrow P1 (Fig. 1b) so that it maintains the nip contact when the size of the paper reel grows.
  • the secondary nip contact is maintained by the first nip member part 2a. This stage is illustrated in Fig. 1b.
  • the paper reel R1 which is formed on the first reeling core 6 has become full, and the reel change threading (the end KP of the cut paper web) has to be conducted by means of the reel change threading apparatus 4 to the reeling core 7 belonging to the second reeling core set, passing the full paper reel R1 formed on the reeling core 6 belonging to the first reeling core set in the machine direction (the end of the paper web remaining on the paper reel R1 being indicated by the letters KV).
  • the reel change threading apparatus 4 is detached from the full reel R1 when the reeling of the paper reel to be formed on the reeling core 7 has begun (reel RA) and the full paper reel R1 is ready to be removed after a stoppage.
  • the threading unit PV which contains a reel change threading apparatus 4, a first nip member part 2a, a second nip member part 2b and a cutting device 5 for paper web, is transferred vertically during the reeling up process.
  • the end of the threading unit PV accommodating the first nip member part 2a is transferred upward when the formation of the paper reel proceeds, in a similar manner, of course, as the end of the threading unit PV at the location of the second reeling core 7 is transferred downward towards the reeling core which is to filled at the next stage (cf. arrow P2 in Fig.
  • the threading unit PV operates in a corresponding manner, but with the opposite direction of motion, in the reeling up process of a paper reel formed on the second reeling core 7 (i.e. when shifting from the stage according to Fig. 1d to the stage according to Fig. 1a).
  • the first nip member part 2a is in a position TR2 corresponding to the removal of the full reel R1, from which it is transferred downward (arrow P4) into a nip contact with the reeling core 6.

  • the threading unit PV can be arranged to be transferred in the vertical direction, advantageously to swing with respect to its centre O (In Figs. 1 a to d corresponding arrows represent the direction of rotation) by means of suitable members (not shown in the drawings).
  • Figs. 2a to f illustrate the functions of the embodiment according to Fig. 1, seen from the top.
  • Figs. 2a and 2b substantially correspond to a situation which is shown from the side in Fig. 1a.
