Definitions

  • the invention relates to a winding device for winding webs, in particular fibrous webs, preferably in the form of paper or board webs with at least a first and a second winding bed forming a support roller against which the winding during winding, wherein the first lying in the fibrous web running direction support roller of this is at least partially entwined, while the second is changeably adjustable in their position via means for axis displacement.
  • the invention further relates to a method for winding a fibrous web in a winding device.
  • Winding devices in the form of so-called Doppeltragwalzenwickelvorraumen are known in a variety of designs. All have in common is that the winding of the wound fibrous web is supported by two support rollers, wherein the two support rollers form a winding bed.
  • a substantial parameter for the subsequent further processing for fibrous webs wound with these machines is the winding hardness.
  • the winding hardness over the entire roll diameter is characterized by a certain course. Ideally, the winding hardness should be constant over the entire roll diameter, but alternatively fall evenly from a certain initial value to a final value.
  • the loading roller is lowered before winding on the empty tube and pushes them with a certain force in the winding bed. Now starts the winding process and grows accordingly the Wickel penmesserr, so the force with which the load roller is pressed against the winding, initially increased. Only when reaching a certain diameter, the weight of the coil sufficient to achieve a good winding result and the contact force is no longer needed. As the winding diameter increases, the load roll moves farther and farther away from the apex line of the roll.
  • the load roller usually acts not on the side on the winding, at which the feed of the fibrous web takes place, but on the side of the second support roller, this leads to a strong increase in the proportion of the force applied via the loading roller force on the first support roller, which leads to a deterioration of the hardening process.
  • axle displacement means are provided for axially parallel displacement of the axis of a support roller relative to the axis of the other support roller.
  • the first support roller seen in the web running direction is designed with a larger diameter than the other second support roller and the axis of the second support roller is considered during the entire winding process in the vertical direction higher than the axis of the first support roller, which is also wrapped by the fibrous web and this leads, arranged.
  • means connected to the axle displacement means are provided, causing a lowering of the axis of the second support roller in response to the increasing diameter of the coil such that the axis of the coil moves along a predetermined vertical or relative to a vertical plane only slightly inclined line of movement, the main load to improve the winding hardness in the fibrous web running direction first gap is supported.
  • the invention is therefore based on the object, a winding device of the type mentioned in such a way that even with displaceable, in particular handlebar-guided load roller as possible a uniform winding density over the entire winding is achieved.
  • a winding device for winding fibrous webs in the form of paper or board webs with a first stationary and a second support roller, which abuts the winding during winding comprises Achsverlagerungsmittel for axially parallel displacement of the axis in the fibrous web running direction second support roller relative to the first support roller, wherein the Displacement according to the invention takes place in such a way that during operation the axis of the second carrier roll in the fibrous web direction in the vertical direction is arranged or displaceable such that the winding nip formed between the winding and the second support roll in a plane or below the other, formed between the first support roll and winding lap is arranged, wherein the second support roller relative to the first support roller via the means for axial displacement is lowered.
  • the weight of the wound coil is increasingly shifted to the second support roller, so that the line pressure in the gap formed between the first support roller and the winding can be kept low, preferably at a constant value, so that the winding hardness is not adversely affected by high line pressures in the first press nip.
  • the adjustment takes place on a circular arc, that is by pivoting.
  • the means for axle displacement comprise a guide device for the second support roller, which is pivotable about the pivot axis by means of a pivoting device.
  • the pivot axis is formed by the bearing axis or axis of the first support roller.
  • the displacement around the outer circumference of the first support roller on a circular arc is always at a uniform distance, in this case with automatic lowering and load by means of a loading roller without significant additional effort when enlarging the coil, that is, depending on the feed rate of the fibrous web and the Drive speed of the individual support rollers, an increase in line force in the second gap formed between the winding and the second support roller is achieved, while the line force in the first gap between the winding and the first support roller can be kept constant, without complex control algorithms for determining the manipulated variable for controlling the adjusting device.
  • the guide means for the support roller is mounted on the bearing axis of the first support roller according to a particularly advantageous embodiment. As a result, an axis parallelism between the support rollers is ensured in a simple manner.
  • the pivot axis is preferably also arranged in a region which allows a horizontal movement in the direction of the first support roller during pivoting.
  • the two support rollers preferably have the same diameter. This offers the advantage of easy adjustability. However, it is also conceivable to make the second carrier roll larger than the first one, as a result of which an increase in the bearing force can once again be achieved here. It is also possible to provide the second support roller with a soft roll shell. In this case, no press nip forms with line contact, but a flat press nip, so that here the surface pressure in the second winding nip between the winding and the second support roller can be significantly reduced, which is positive for the winding quality.
  • the required ratios can also be adjusted by shifting both support rollers.
  • These are stored in the simplest case on a rocker whose pivot axis is below the bearing axes of both support rollers in the neutral position and which is arranged parallel to these.
  • the pivot axis of the rocker is arranged in the region of the bearing axis of the first support roller.
  • the pressing of the roll by means of a corresponding load roller is preferably handlebar-guided, that is, compared to a pre-settable on the handlebar force this is pressed upon enlargement of the coil against the handlebars and thus moves in the radial direction relative to the winding axis to the outside.
  • the inventive method for winding a fibrous web wherein the winding is applied to a first and second support roller during the winding process, wherein the first support roller partially wrapped by the fibrous web is stationary and is carried out, characterized in that the winding hardness depending on the increase of the winding size, in particular the diameter, the second support roller relative to the first support roller from a position in which this with its axis in a plane or below the axis of the first Roller is lowered, is lowered.
  • the second bearing axis of the support roller is pivoted.
  • the pivoting is preferably carried out about the bearing axis of the first support roller, in which case an accurate axis-parallel guidance is given.
  • the winding process is performed with constant contact pressure on the pressure roller. Furthermore, the contact pressure can be controlled.
  • a reduction is not made immediately, but only when the winding has reached a predefined minimum size and the bearing force in individual Wickespalten does not exceed a certain value.
