Definitions

  • the invention relates to a reel winding apparatus having a longitudinal cutting device and a winding station for winding part webs cut from a material web into winding reels, which has a first winding device with a central roll and winding positions arranged on both sides of the central roll, which are offset in the axial direction of the central roll. Furthermore, the invention relates to a method for producing winding rolls, in which one divides a material web by longitudinal cutting into partial webs and feeds the partial webs of a first winding device having a central roll and both sides of the central roll arranged winding positions, offset in the axial direction of the central roll to each other at 15, are ordered.
  • Paper webs are currently produced in widths of up to 11 m.
  • the paper web In order to be manageable for a later user, such as a printing company, the paper web must be divided into narrower strips, the so-called partial webs, and wound up into winding rolls.
  • the winding rolls have an axial length in the range of 0.2 to 5 m and a diameter in the range of 0.5 to 2.5 m.
  • a winding roll can only take a limited length of a partial web. Once the winding roll has reached its predetermined diameter, the part web must be separated and a roll core of a new winding roll be supplied. This has the consequence that between the individual winding operations relatively large dead times are necessary in which practically not wound, but only prepared. Due to these time losses, such a reel-winding device must wind at a speed which is greater than the speed of a paper machine previously arranged in a production process. In many cases, therefore, you need even more reel winders to keep up with a paper machine can.
  • the roll winding device has a winding device with a central roll and arranged on both sides of the central roll winding positions, which are arranged offset in the axial direction of the central roll to each other.
  • the invention has for its object to be able to keep dead times small or even eliminate.
  • a reel winding device of the type mentioned above in that a second winding device, which uses the central roller, arranged on both sides of the central roller winding positions, which are offset in the axial direction of the central roller to each other, and the partial webs alternately in the first winding device and are guided in the second winding device.
  • the two winding devices are thus designed as so-called contact winders, ie the individual winding rollers are applied to the central roller during winding. This makes it possible, during winding wrap a certain winding tension in the winding roll, so that you can reach a predetermined winding hardness.
  • the bobbins partly rest against the central roll with their own weight.
  • the necessary pressure is generated from outside. If in the following of a contact roller winder is mentioned, then this term should also include a backup roller winder. So far, the partial webs have always alternately fed the winding positions, on both sides of the central roller are arranged.
  • first winding device and the second winding device are arranged on opposite sides of the central roller. This makes the best use of the space available at the central roller.
  • first winding device in the direction of gravity at the top and the second winding device in the direction of gravity are arranged at the bottom of the central roller.
  • first winding device in the direction of gravity at the top and the second winding device in the direction of gravity are arranged at the bottom of the central roller.
  • Each winding position preferably has a pre-acceleration device for a winding tube.
  • This pre-acceleration device can be formed by a corrugated tube drive. But it is also possible that the Vorbeschreibungs device simply presses the winding tube against the central roll and can accelerate it by frictional force. If the winding tube has been accelerated to the peripheral speed of the central roller, then the partial web can be transferred practically without stopping by the full winding roll on the empty winding roll.
  • each winding device has at least one splicing device.
  • the splice device With the splice device, the material web is severed after reaching the desired diameter of a full winding roll and a new roll core, which is arranged in the free winding position supplied.
  • the splicing device can thus achieve a so-called "flying splice" or flying change, i. the winding does not have to be interrupted, so that virtually no dead times occur due to a roll change. Even if you have to lower the winding speed when changing from a full to an empty winding roll, there are still time advantages.
  • the splice device is movable in the axial direction of the central roller. It is therefore no longer necessary that the splice device covers the entire axial length of the central roll. Rather, it is now possible to ensure that the splicing device works off one winding roll after the other, so to speak. The splice device must be so have only a limited working length. The narrower the partial webs are, the easier it is to make a transition from the full to the empty winding reel.
  • differently sized bobbins are arranged in at least two winding positions. It can be with this configuration ensure that not all bobbins are finished at the same time, but the transition of the partial webs of a full winding roll on an empty winding roll can be staggered in time one behind the other. This simplifies the control of the reel winder.
  • a pulper opening is arranged behind the longitudinal cutting device. For example, when feeding the partial webs, it is then possible first to let some partial webs run into the pulper until other winding rolls have reached a predetermined diameter. With this configuration it is ensured that the winding rollers have different diameters during later winding.
  • the reel winder is arranged on-line with a paper machine, a coater or a calender. Since the change from a full winding roll to an empty winding roll can be done practically without loss of time, because sufficient reserve positions are available, such on-line operation can be realized.
  • the longitudinal cutting device has at least one knife arrangement which, in the cutting state, can be moved parallel to the axis of the central roll.
  • a change of the cutting plan during winding is possible.
  • winding rolls produced when changing the cutting plan can not be further processed in the rule.
  • the partial web wound up here must be disposed of. But since changing the cutting plan requires only a relatively short time, this disadvantage can be accepted. So far, one had to always diverge the blades of a knife assembly and remove the web to properly position the knife assemblies. This is no longer necessary.
  • winding positions of the winding means relative to each other are adjustable so that the sum of the length of the winding tubes is greater than the width of the material web. This is possible by having two winding devices available. Such a design facilitates the change of the cutting plan, because you can make virtually any changes in width.
  • transition cores are provided with a relation to normal cores enlarged diameter.
  • On the transition cores only comparatively few turns are wound, namely as many turns, as required, to accommodate a portion of the sub-web can, whose width changes.
  • these transition rollers have to be removed from the winding device, then they usually roll off on their circumference. The larger this circumference is, ie the larger the diameter of the transition rollers, the better the rolling behavior.
  • With a larger winding core, ie a larger winding tube the increase in diameter can be realized in a simple manner.
  • the object is achieved in a method of the type mentioned above in that one feeds the partial webs alternately two winding devices, each of which has a central roller and on both sides thereof arranged winding positions, wherein a common central roller is used for both winding devices.
  • the partial web is guided into the free winding position of the same winding device lying opposite the winding position.
  • This makes it possible to shorten the dead time considerably. In most cases, it is not necessary to shut down the winder when passing. On the contrary, it is possible to continue the winding device at reduced speed or in some cases even at full speed.
  • individual partial webs are run in a pulper until already wound winding reels have reached a predetermined diameter.
  • a predetermined diameter In other words, so you cut, as before, from a web of material a predetermined number of partial webs and leads, for example, only two partial webs in the two winding devices, in each winding device one.
  • the next two partial webs are passed into the two winding devices.
  • the first two partial webs continue to wind, so that when winding the second two partial webs, the corresponding winding rollers also increase their diameter. It can thereby be achieved that the first winding rolls are finished when the last partial webs have begun to wind.
  • the width of at least one partial web is changed during winding.
  • One is thus able to make a change in the cutting plan when winding.
  • the desired train remains on the partial webs.
  • a partial web section whose width changes is wound up and disposed of.
  • Such a sub-web section will be unfavorable for further processing in the rule. But since it is only a matter of small lengths, this part of the web section can be returned to paper production.
  • a larger roll core is used for winding up the partial web section. This automatically increases the circumferential surface of a roll which receives the partial web section with a changing width, so that the rolling behavior improves in such waste rolls.
  • the partial web can be run in the pulper, thereby changing their width by adjusting a longitudinal cutting device and feeds the partial web back to the winding position when the desired width is reached.
  • a longitudinal cutting device adjusting a longitudinal cutting device and feeds the partial web back to the winding position when the desired width is reached.
  • a roll winding device 1 has a first winding device 2 and a second winding device 3. Both winding devices 2, 3 have a common central roller 4. On both sides of the central roller 4, approximately in the middle of the two upper quadrants of the central roller 4, a plurality of winding positions 5, 6 of the first winding device 2 are arranged, of which two are visible in Fig. 1. The other winding positions are parallel to the axis of the central roller 4 behind it.
  • the second winding device 3 has the same central roller 4, on both sides winding positions 8, 9 are arranged.
  • the winding positions 8, 9 are located in the two lower quadrants of the central roller 4th
  • the source 11 may be a paper machine, a coater or a calender.
  • the roll winding device 1 is thus arranged on-line to this source 11.
  • the longitudinal cutting device 14 has upper blade 15 and lower blade 16, wherein in each case an upper blade 15 cooperates with a lower blade 16
  • the longitudinal cutter 14 divides the paper web 10 into a plurality of partial webs 17a, 17b, 18a, 18b which are fed in groups to the first winding device 2 or the second winding device 3.
  • a pulper 19 is arranged with an opening 20 into which the paper web 10 or partial webs 17a, 17b, 18a, 18b can run.
  • the winding devices 2, 3 are each constructed in the manner of a contact roller winder, i. Winding rolls 22-25, which form from the partial webs 17a, 17b, 18a, 18b, abut against the central roll 4 and migrate with increasing diameter along guideways 26 obliquely upwards (winding device 2) or downwards (winding device 3), for example, at an angle of 45 ° to the vertical.
  • the cores 30, 31 are mounted in guide heads 32, 33.
  • the guide heads 32, 33 may also have a rotary drive.
  • Fig. 2 the common central roller 4 is shown twice, namely once from above with the winding device 2 and once from below with the winding device. 3
  • the partial webs 17, 18 are now fed alternately to the two winding devices 2, 3.
  • the partial webs 17 wrap around the central roller 4 so that they are fed either to a winding roll 23 or a winding roll 22.
  • Between these two winding rollers 22, 23 is located in the axial direction of the central roller 4 is a clear distance 34.
  • Opposite the winding roller 22 is a free winding position with the winding tube 31.
  • Opposite the winding roller 23 is a free winding position with the winding tube 30. Due to the gaps (ent-speaking gaps also arise between the other in the Wrapping device 2 wound bobbins) is enough space available to prepare the cores 30, 31, which are in the free winding positions.
  • the cores 30, 31 can be provided with an adhesive strip or otherwise tackified, so that after the completion of a winding roll 22, 23, the sub-webs 17a, 17b can be transferred to each located in the free winding positions winding sleeves 31, 30 as shown by arrows 35a, 35b.
  • each winding roll 24, 25 there is a free winding position in the empty winding tubes 36, 37 can be prepared to receive partial webs 18a, 18b can, as indicated by arrows 38a, 38b.
  • each Wickelei device 2, 3 is a cross-cutting device 39, 40 associated with the incoming partial webs 17, 18 can cut individually or together. With the help of guiding devices 41-44, the corresponding partial webs 17a, 17b, 18a, 18b are then fed to the respective free winding position.
  • the individual winding rollers 22, 23 and 24, 25 quite different diameters. This is desired. These different diameters can be produced, for example, by inserting the paper web 10 into the roll winder 1 not all partial webs 17, 18 leads to the winding devices 2, 3, but some sub-webs run in the pulper 19, as indicated in Fig. 1 with a dashed line (end 21). Only then, when a winding roll 22, 24 has reached a predetermined diameter, the next partial webs are passed into the winding devices 2, 3. Continued winding further increases the diameter of the wound rolls wound first, while the diameter of the wound rolls wound thereafter remains smaller. This is continued until all winding positions are occupied by bobbins.
  • the knives 15, 16 of the slitter 14 can be moved while cutting. This makes it possible to change the cutting plan, ie the widths of the individual partial webs 17, 18. For this purpose, it is only necessary that one provides in the free winding positions winding tubes 30, 31 and 36, 37, which is wide enough for the widest region of a partial web section whose width changes. So it may well be that the sum of the lengths of all cores of the two winding devices 2, 3 is longer than the width of the supplied paper web 10th
  • the sub-web sections whose widths change, can not be used for further processing in most cases. It is therefore expediently wound on a transition winding tube whose diameter is greater than the diameter of a winding sleeve normally used. This gives you a waste roll with an enlarged diameter that can be rolled out better.
  • the partial webs 17b, 18a As soon as the partial webs 17b, 18a have reached the desired width, they are transferred to the new roll cores 31, 36. You can then start the winding of new bobbins with a different width. Depending on the speed of the partial webs 17, 18, although a certain length of the partial webs is lost. However, the loss is relatively small because the adjustment of the longitudinal cutting device 14 can be done relatively quickly. When adjusting, you do not even have to make sure that the cutting edges are smooth. The only condition is that the sub-webs do not tear when changing the width.
  • the invention enables a winding of the partial webs with relatively great flexibility and relatively little design effort.
  • All partial webs 17, 18 revolve around the central roller 4 in the same direction to its winding position. Dividing the central roller 4 into four quadrants I, II, III, IV, so for example at a certain time in the quadrant I, the one half of the partial webs are wound up. In Quadrant II then wait a correspondingly large number of empty tubes on the same tracks that are taken when the roll wraps on quadrant I have reached their desired size. Similarly, the same arrangement applies to the other half of the partial webs, which are wound in the quadrant III and later transferred to the quadrant IV. This procedure requires only a central roller 4 and ensures a quick change.
  • the central roller 4 at which the track ends are somehow held, just by a quarter turn to be moved and already the trailing ends have reached their new winding position.
  • the full bobbins can be removed and replaced with new sleeves, for which again enough space and handling space is available.
