    INTRODUCTION DEVICE FOR A WINDING AXLE FOR FIBER MATERIAL
    The invention relates to an insertion device of a winding axis for fiber material, the elongated body part, along the body part back and forth movable sliding part for pushing the existing in connection with the insertion winding axis with a longitudinal movement to a winding station and organs for moving the Has winding axis in the growth direction of the wound fiber web material.
    In papermaking, the web of an emerging machine role has its full breadth and is even over 100 km long, so that this cut for the customers of the paper mill before delivery from the factory to a suitable width and length in partial webs and a winding core around as so-called customer roles must be rolled up. This slitting and winding of the web takes place according to the prior art, as is known, in a suitably separate machine or in a slitter.
    The machine roll is known to be wound in a slitter; The wide web is cut in a cutting section into several narrower partial webs, which are wound in a wrapping around winding cores, such as around sleeves, as customer roles. Cartridge roller winders are often used in the slitter winder in which the partial webs are wound by two carrier rollers to partial web rolls are wound over a nip between the nip and the fiber web roll to be formed. As a carrier roll, a belt arrangement positioned around two guide rolls, that is to say a so-called belt rolling mill, can also be used. When the customer rolls are finished, the slitter is stopped and the rolls or so-called offset removed from the machine, after which the process continues with the winding of a new offset. These operations are repeated periodically until the paper on the machine roll ends, after which the machine roll is changed and the process begins anew with the winding of a new machine roll. In the wrapping section or in the winder, the sleeves arranged one behind the other in the longitudinal direction are locked as a row of sleeves on a sleeve tensioning device positioned at both ends.
    In the earlier patent publication FI116282 of the applicant of the present patent application, a method and an apparatus is described with a slitter, which is to be used in connection with the winding of a paper or board web, in particular a tissue paper web, wherein for the duration of the winding Winding axle is brought into the sleeve. The fibrous web is supported by the backing rolls as web rolls wrapped around the sleeves. As the winding progresses, the winding axis is shifted into the sleeves in the direction of growth of the web rolls to be formed, and after completion of the web rolls, the winding axis is removed from the sleeves, after which a new winding begins and new winding sleeves are brought to support the backing rolls. This solution also allows winding without sleeves.
    In Figs. 1A-1B, the initial phases of the method according to patent FI116282 are shown schematically. In Fig. 1A, the initial phase of a winding is shown. Empty sleeves 5 are brought to support carrier rolls 6, 7 and a winding axis 3 is in provision. The fixed end of the winding shaft 3 is fixed to a traction slide 2 for the axis, which moves in the figure in a guide 1 in the vertical direction. The pulling slide 2 and the guide 1 on the side of the fixed end of the winding shaft 3 are arranged in the figure movable in the vertical direction, so that the winding shaft 3 can be brought to the winding station in the sleeves 5 and pulled out after winding from these. The free end of the winding axis 3 is supported by a support element 15. The winding axis 3 is pushed in the direction indicated by an arrow 5 in the figure in the horizontal direction in its place in such a way that the free end of the winding axis 3 is attached to another Zugschlitten 8, which in other, in the figure vertical direction arranged guides 9 1 π Austrian Patent Office AT12 870U1 2013-01-15 moved.
    In Fig. 1B, a phase is shown, in which the winding has begun and the winding shaft 3 is located in the winding station. The winding axis 3 is pushed through the sleeves 5 in such a way that their free end is fastened to the other axial slide 8, which moves in guides 9. The Achsenzugschlitten 2, 8 move in the course of the winding in the formation of fiber rollers 4 around the sleeves 5 around in the direction indicated by arrows SY in guides 1,9 upwards.
    The solution according to patent FI116282 works as such, but problems can be caused by occurring vibrations during winding and in particular by an eccentric rotational movement, in which the winding axis is not in the center of rotation of the wound roll. Such eccentricity causes a forced vibration on the winding axis, which increases as the eccentricity increases. At the forced vibration in addition to the mass of the winding axis itself and the sliding elements of the insertion and the parts of the body structure involved. Eccentricity is easier with thicker fibrous webs, such as cellulose, but this can also occur on other fibrous webs.
    The object of the present invention is to bring about an improved insertion device for the winding axis, which involved in the forced vibration mass can be substantially reduced. To achieve this object, it is characteristic of a solution according to the invention that the winding axis positioned inside the fiber web roll is separated from the body part of the insertion device at least in the direction of one degree of freedom with respect to the central axis of the winding axis substantially in a rectangular plane. The solution according to the invention is particularly suitable for a cellulosic web and for soft paper, but can also be adapted to other paper grades and to paperboard.
    In the following, the invention will be explained with reference to the attached drawings, wherein Figs. 1A-1B schematically show some phases of a winding process according to the prior art
    Fig. 2 generally illustrates the basic principle of an insertion device according to the invention, schematically seen from a side view, Fig. 3 shows an example of an embodiment for an insertion device according to the
    FIG. 4 shows an example of an embodiment of an insertion device according to the invention. FIG
    Invention schematically seen from a second end view.
    In Fig. 2, the same reference numerals as in Figs. 1 A-1 B were used for the corresponding parts. The insertion device includes a body part 2 'which moves along vertical guides 1 and a pulling carriage 2 arranged moving back and forth along it, to which a winding axis 3 is connected. The movable winding axis is pushed with a movement in the longitudinal direction by means of pulling slide 2 in the interior of winding tubes 5. As a drive for the drive slide 2, for example, a hydraulic cylinder (not shown) may be provided. The fiber web roll 4 to be formed is supported by support rollers 6, 7. The pulling carriage 2 can be permanently attached to the winding axle or can be arranged to be detachable from the winding axle for the duration of the winding as being connected to the winding axle for the duration of pushing the winding axle into the winding station and pulling the winding axle out of the winding station.
    In Fig. 3, an example of an embodiment of the invention is shown schematically from an end view, wherein the traction slide 2 is permanently attached to the winding axis 3. The body part 2 'of the pulling carriage is arranged on vertical guides 1 movable on a hydraulic cylinder 11. The pulling carriage 2 moves, for example, in plain bearings (not shown) on the body part 2 'along and the winding axis 3 connected to the pulling carriage is connected to the body part 2' by means of a connecting rod 13.

    Austrian Patent Office AT 12 870 Ul 2013-01-15 ckelachse 3 is for example with a sliding bearing (not shown) mounted in the manner in the articulated rod that he is able to push in a vertical movement through the located on the hinge rod 13 mounting hole. With this joint solution, the forced vibrations of the winding axis can be separated from the body part 2 'of the pulling carriage, whereby the vibrating mass is considerably reduced. 4, an embodiment is shown in which the traction slide 2 for the duration of winding of the winding axis 3 is releasable. The body part 2 'of the traction carriage and the traction carriage 2 move in vertical guides, supported by a cylinder 12 following the movements of the winding axis 3, which is connected to the articulated rod 13 supported by a cylinder 11. With this solution, the pull slide 2 can be separated from the forced vibrations of the winding axis. The required energy supply, for example a compressed air supply 16, is preferably connected to the guide chain (not shown) arranged for the pulling carriage.
