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 arranged offset to one another 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 winding station, which has a central roll and arranged on both sides of the central roll winding positions.
  • a reel winding apparatus is known from US 6,007,014 known.
  • 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 reaches its predetermined diameter has, the partial web must be separated and fed to a roll core of a new winding roll. 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 invention has for its object to be able to keep dead times small or even eliminate.
  • a roll winding device of the type mentioned in that a second winding device with a central roll and arranged on both sides of the central roll winding positions, which are offset in the axial direction of the central roll to each other, is provided, and the partial webs alternately in the first winding device and in the second winding device are guided.
  • the two winding devices are thus designed as a so-called support or contact winder, ie the individual bobbins are applied to the central roll during winding. This makes it possible, during winding to wrap a certain winding tension in the winding roll, so that you can reach a predetermined winding hardness.
  • a back-up roll winder the bobbins partly rest against the central roll with their own weight.
  • a contact roller winder the necessary pressure is generated from outside. If in the following of a back-up roll winder is mentioned, then this term should also include a contact roller winder. You have so far the partial webs always alternately supplied to the winding positions, which are arranged on both sides 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 therefore 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. You can now, for example, while performing the partial webs first run some sub-webs in the pulper until other reels 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. With such a knife assembly you can then change the cutting plan during operation.
  • 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 greater than the width of the web is. 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 extent is, i. the larger the diameter of the transition rollers, the better the rolling behavior. With a larger hub, i. a larger winding tube, the diameter increase is easy to implement.
  • the object is achieved in a method of the type mentioned above by alternately supplying the partial webs two winding devices, each of which has a central roller and arranged on both sides winding positions.
  • 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.
  • winding tube located in the free winding position. If the winding tube has the same peripheral speed as the central roller and thus as the incoming part of the web, then you can fix the part of the web, which has been separated from a full winding roll readily on the new winding tube and continue the winding process. Interruptions are then practically no longer necessary.
  • 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 material web 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 coil, the part of the web section changing with Width absorbs, so that the rolling performance improved 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.
  • the first winding device 2 has a central roller 4.
  • the other winding positions are parallel to the axis of the central roller 4 behind it.
  • the second winding device 3 also has a central roller 7, on both sides winding positions 8, 9 are arranged.
  • the winding positions 8, 9 are also located in the two upper quadrants of the central roller. 7
  • 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 and the outer blade 15 are arranged perpendicular to the plane one behind the other, just like the lower blade 16.
  • the longitudinal cutting device 14 divides the paper web 10 into a plurality of partial webs 17, 18, the groups of the first winding device 2 or the second winding device 3 are supplied.
  • a pulper 19 is arranged with an opening 20 into which the paper web 10 or partial webs 17, 18 can run, as is indicated by an end 21.
  • the winding devices 2, 3 are each constructed in the manner of a back-up roll winder, ie winding rolls 22-25, which are formed from the partial webs 17, 18, abut against the central rolls 4, 7 and move with increasing diameter along guideways 26-29 obliquely above, for example, at an angle of 45 ° to the vertical.
  • a back-up roll winder ie winding rolls 22-25
  • winding rolls 22-25 which are formed from the partial webs 17, 18, abut against the central rolls 4, 7 and move with increasing diameter along guideways 26-29 obliquely above, 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.
  • 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 the two winding rollers 22, 23 is located in the axial direction of the central roller 4 is a significant 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 wound in the winding device 2 winding rollers) is enough space available to the winding tubes 30, 31, which are in the free winding positions to prepare.
  • 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 central roller is associated with a cross-cutting device 39, 40, which can cut through the incoming partial webs 17, 18 individually or together.
  • 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 not leading all of the partial webs 17, 18 to the winding devices 2, 3 when the paper web 10 is fed into the roll winding device 1, but instead allowing some partial webs to run into the pulper 19, as shown in FIG 1 with a dashed line (end 21) is indicated. 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. It may well be that the sum of the lengths of all the winding tubes 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 winding new rolls with changed 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.
