Definitions

  • the invention relates to a method for transferring a Roll of material from one in a changing bed, by at least a first and a second carrier roller is formed, lying reel on a new roll core, in which the material web is cut and the end thus formed on the winding roll and the beginning is set on the roll core. Further
  • the invention relates to a winding device for winding a material web to a winding roll with a Changing bed made by at least a first and a second support roller is formed and an inlet path which runs above the first support roller, a separating device, an adhesive application device and an ejector.
  • the invention is based on a paper web described as an example of a material web. she is however, in principle also with other material webs Applicable to making salable and manageable Winding rolls must be wound up. At the winding rolls are larger winding rolls, their width in the range of 0.3 to 3.8 m and their Diameter is in the range of 0.8 to 2.5 m.
  • Paper webs become almost endless in a paper machine produced.
  • a winding roll can only do one Record the finite length of the paper web. It is therefore from time to time necessary to interrupt the winding process, to cut the paper web, the resultant Fix the end on the winding roll and the To attach to a new roll core.
  • Roll core is usually a cardboard tube.
  • the paper web breaks by.
  • the beginning of the paper web is already through the end of the paper web up to the changing bed or at least pulled close to the changing bed.
  • the invention is based, with simpler the task To keep the web guide short the time for transfer.
  • This task is carried out in a method of the type mentioned at the beginning Art solved in that the material web of the winding roll is fed into the top of the changing bed when separating to form a gap to the first Carrier roller is tilted towards the changing bed and the Material web is cut in the gap.
  • Creating the gap between the first carrier roller and the winding roller allows that you have a separator, for example a the axially extending knife-extending knife, passes through the material web. This allows a clean and clearly defined cut that also in the case of thicker material webs, cut with the desired accuracy.
  • the material web is preferably held when the Winding roll and cutting the material web on the first support roller and twists the first support roller when tilting the winding roll.
  • the Fixed the beginning of the material web on the support roller see above that after cutting it easily into the changing bed can bring in.
  • By turning the support roller on the other hand, one prevents inadmissible tension in the material web when tilting the winding roll. If you tilt the reel and twist it matches the first carrier roller accordingly, then there are short free trains that have a certain amount Have tension so that you can cut quickly and precisely by retracting a knife can.
  • the material web from below severed. So you can get the one you need Separating device during winding in the changing bed hold so that it does not bother, but to separate is available with a short movement.
  • Adhesive surfaces on the material web that run in the direction of travel have a distance from each other and cuts through the Material web at this distance.
  • the two adhesive surfaces serve to end the web of material on the winding roll and the beginning of the material web on the roll core to fix. By making a distance between provides these two adhesive surfaces prevented to stick the material web to the knife or the separation device and contamination of the separation device.
  • the first adhesive surface serves the end of the material web to attach to the circumference of the winding roll.
  • Reliable gluing is outlined here important because this bond is basically the only one Attachment of the end of the material web to the circumference the winding roll is.
  • the beginning of the material web is on the other hand on the roll core not only through the adhesive surface captured. Rather, this only serves at the beginning of the winding process as the only connection. After a few Rotations of the roll core then hold it wound winding layers at the beginning of the material web Roll core firmly.
  • the winding roll is preferably cut after being cut ejected from the changing bed and the beginning of the material web conveyed into the changing bed at the same time. By synchronizing both movements, time can be saved. The expulsion must but not immediately after cutting. The role is expediently so long rotated further until the glued web end between the nip the roller and the second support roller. Only then will the role be launched, starting with the material web at the latest with this ejection, if necessary but also encouraged when the filming continues becomes.
  • the start of the material web is advantageously at the first carrier roller until the roll core lies against the material web. This saves you one complicated new introduction of the material web in the Winding device.
  • the task is also in a winding device solved type mentioned, in that the changing bed has an entry path that is at the top
  • the separating device runs over the first support roller arranged in the changing bed and to the inlet side of the material web is movable and the ejection device Holding device which the web of material on holds first carrier roller.
  • the first support roller is preferably synchronous with the ejection device movable. Since the material web on the first support roller with the help of the holding device you can make sure here that the material web conveyed when moving the ejector becomes. This can be used to ensure that the Cutting the material web in a defined way Shape takes place. The web of material breaks not before cutting off. this has particular advantages if the dividing line between the beginning and end of the material web as precisely as possible between individual adhesive surfaces should run.
  • the ejection device a Has lever that around the axis of the first support roller pivotable and fixable relative to the first support roller is. If the lever opposite the first carrier roller is set, then the ejector moves without additional measures in sync with the Carrier roller and vice versa, i.e. with a movement of the Ejection device used to tilt the winding roll the winding bed leads out, the first support roller in adjusted accordingly.
  • the ejection device advantageously has a Control device that the ejector after Abutment on the winding roll for a predetermined distance moved on and then stops. So you can reach the desired tilting movement, i.e. the winding roll remains with her main focus still in the changing bed, but forms with the first support roller a nip through which the Separator can be moved.
  • the ejector essentially has one clamping roller movable radially to the first carrier roller on.
  • the web of material can be clamped easily fix on the first carrier roller.
  • the pinch roller is arranged on the lever is. This results in the desired synchronous Movement between the material web, the first carrier roller and the ejector.
  • Fig. 1 shows a roll winding device 1 with a first support roller 2 and a second support roller 3, the together form a changing bed 4.
  • a winding roller 5 rests by winding one material web 6 tapering over the first support roller 2, for example a paper web is formed.
  • Such double carrier roll winder can be axial several winding rolls 5 in succession at the same time be wound, for example, when the Roll winding device 1 a not shown Slitter is connected upstream.
  • the roll winding device has 1 a separation device 7, the a knife which may be curved in the circumferential direction 8, which is attached to a lever 9 which around the axis 10 of the first support roller 2 is pivotable.
  • a separation device 7 the a knife which may be curved in the circumferential direction 8, which is attached to a lever 9 which around the axis 10 of the first support roller 2 is pivotable.
  • the separator 7 When winding, the separator 7 rests in or below of the winding bed 4, that is between the two support rollers 2, 3, where it doesn't bother you.
  • the web of material 6 runs from above over the first support roller 2 in the changing bed 4, so does not come into conflict with the separating device 7.
  • an adhesive application device 11 in Operation set in the direction of the web a first adhesive surface 12 and a second adhesive surface 13 generated on the material web 6.
  • the first adhesive surface 12 is essential here in the running direction extended further than the second adhesive surface 13. Between the two adhesive surfaces 12, 13 remain uncovered Strip 14.
  • An ejection device 15 has an ejection roller 16 and a pinch roller 17 mounted on a lever 18 are that about the axis of rotation 10 of the first Carrier roller 2 is pivotable.
  • the pinch roller 17 is here essentially in the radial direction to the first Carrier roller 2 movable to and away from it.
  • This gap 19 is traversed by the material web 6, with between the material web roll 5 and the first support roller 2 short "Free web trains" arise in which the material web 6 is kept under a certain tension.
  • the If necessary, voltage can be controlled by that the second support roller 3 with a certain advance is driven relative to the first support roller 2.
  • the knife 8 is now in the tensioned material web 6 retracted and cut by pivoting the lever 9 the material web 6 in the gap 19. If several Winding rolls 5 have been wound at the same time, then all material webs are also cut 6 essentially simultaneously. The cut must not at the narrowest point of the gap 19. It depends among other things on the exact position of the knife 8 from. In any case, with the knife 8, that dips into the tensioned web of material 6, clean Dividing lines largely independent of the thickness and the Achieve basis weight of the material web 6 to be wound.
  • 3A shows a detail Y here Fig. 3. The cutting can still be done if necessary improve something if you briefly the second support roller 3 spun. The winding roller turns 5 on the second support roller 3 and the ejection roller 16.
  • the separating device 7 is again after cutting in its basic position between the two support rollers 2, 3 pivoted back (Fig. 5). Another one Swiveling the lever 18, the winding roll 5 is off the changing bed 4 tipped out, specifically over the second Carrier roller 3. Simultaneously with this movement of the Lever 18, the first support roller 2 is rotated so that the material web 6 with the second adhesive surface 13 likewise is advanced.
  • the Swivel path of the pivot lever 18 depends on Diameter of the winding roll 5 from. The smaller this one Diameter, the larger the swivel path. The Swivel path also determines the extent to which that new web end is advanced.
  • the system can be set up so that the glued The beginning of the web always comes to the right place. In In practice, however, it often happens that the Roll diameter changes. In this case, the glued Tip "be readjusted". For example by doing the system Swivel lever 18 / pinch roller 17 / support roller 2 accordingly forwards or backwards.
