Definitions

  • the invention relates to a method for simultaneous Winding of several partial webs from one material web be cut into partial web rolls. Further The invention relates to a device for simultaneous Winding of several partial webs to partial web rolls with at least one winding position group, in of which several partial web rolls are arranged.
  • the invention is based on a paper web described as an example of a material web. she is but also applicable to other material webs based on must be handled and wound up in a similar manner.
  • Paper webs are nowadays with relatively large widths, which can be up to 10 m. Such large widths are not for most users more manageable., The paper webs are therefore in one the last manufacturing steps in narrower partial webs cut, the width of which ranges from 0.5 to Can be 3.8 m. These partial webs then become Partial web or winding rolls wound up, some Have final diameters in the range of 0.5 to 2.5 m. Such winding rolls are then packed and attached to the Consumers, such as a print shop, shipped.
  • one of the support rollers can also be replaced by a band arrangement.
  • the partial web rolls are supported centrally and lie with their extent on a support or Contact roller. Because with this winding between the individual web rolls in the axial direction a certain Clearance must exist to accommodate holder facilities There are two winding position groups available here provided in which the individual Partial web rolls are arranged to gap to each other.
  • the invention is based, the control options to improve when wrapping.
  • This task is carried out in a method of the aforementioned Art solved in that predetermined parameters each individual sub-web roll are recorded continuously.
  • the parameters of the partial web rolls are preferred continuously compared with each other.
  • Deviations between partial web rolls immediately to capture can, for example indicate a tear of the material web.
  • An outline is for example when winding a paper web roll highly problematic if it is not recognized in time becomes. Since paper web rolls at speeds of it is conceivable to wind well over 1000 m / min that with such a mistake an easily unwound Material web section of considerable size can arise. This web of material can then become uncontrolled wrap around any machine components and cause damage there. A web break was previously only recognizable by the fact that has measured the tension in the material web.
  • the winding is interrupted when there is data between partial web rolls Differences result in a predetermined value exceed. Even if several partial webs from the cut the same material web are smaller Differences practically unavoidable. This is because with a paper web, for example, that the Headbox transverse to the running direction is not absolutely constant can hold.
  • the material web is usually slightly thicker in the middle than at the edges. Accordingly, for example, the weight and the diameter of a partial web roll, which from the Cut the middle of the material web, enlarge it more than the weight of partial web rolls from the Edge. Still, you can with some reliability predict how big differences can be without indicating a mistake.
  • a relatively safe one The main indication of the existence of an error is given when the parameters of partial web rolls change while the same parameters differ from others Do not change part web rolls.
  • the data is preferably only acquired from a predetermined one Diameter of the partial web rolls.
  • the reason for this is that you can change parameters for smaller ones Record diameters only with a relatively high effort can. It is assumed that errors, for example Web breaks, usually only from a certain point Diameters occur while smaller Roll diameters are relatively rare.
  • the diameters of the individual are preferably used Partial web rolls as data.
  • the diameter of the partial web rolls can be recorded relatively easily, for example with a feeler roller. The effort for that Recording of the data of the partial web reels therefore remains small.
  • each sub-web role Sensor is assigned that continuously at least one predetermined parameters of this partial web roll determined.
  • This sensor can be used during winding monitor the progress in building the partial web roll. This makes it possible to have one for each web roll Keep a log or "log book” from which you can get valuable Gain information about the structure of the partial web role can.
  • the sensor is preferably designed as a diameter sensor.
  • the diameter of the partial web roll is a relative one easy to grasp parameter.
  • the increase in diameter over time is at constant winding speed well predictable, so deviations can easily be recognized by this increase.
  • the sensor is preferably provided with a load roller coupled, which acts as a sensing roller.
  • a load roller coupled, which acts as a sensing roller.
  • Such Load roll is in many winding devices available anyway, especially at the beginning of a winding process the partial web roll that forms against one Back-up or contact roller or in the changing bed press to a high at the beginning of the winding process To produce winding hardness. You can now with relatively little Effort of this burden role an additional function transferred, namely it as a tactile role for one Use diameter sensor.
  • the loading roller is preferably in the axial direction divided into segments, the segments by a coupling device can be coupled and a common Have rotary drive.
  • a diameter detection the stress role is not yet absolutely necessary use as an additional means to torque in enter the partial web rolls that are being formed. This further torque can increase the winding hardness be used.
  • that the sensors are connected to a comparator are part of a drive control. If the comparator finds that from the sensors determined diameters are very different or a diameter no longer changes while the other diameters change, then obviously lies an error before. The comparator can then in the drive control and the winding device for example, stop.
  • Fig. 1 shows a schematic side view in Fig. 1a and in Fig. 1b a front view of a roll winding device 1.
  • the roll winding device 1 has a winding bed 2, which is supported by two support rollers 3, 4 is formed. In the winding bed 2 lie in the axial direction next to each other several winding rolls 5, which are shown in Fig. 1b are designated 5a, 5b, 5c and 5d.
  • the winding rolls 5a-5d are caused by the rotation of the support rollers 3, 4 or at least one of the two support rollers 3, 4 driven and thereby pull a not shown Material web previously cut into partial webs has been on a roll core 6.
  • the side by side lying winding rolls 5a-5d are also used as winding rolls designated.
  • a support roller 7 lies on the winding rollers 5a-5d on. As can be seen from Fig. 1b, the support roller 7 in the axial direction in a plurality of sections 7a-7h divided. Each section 7a-7h is on two Levers 8 rotatably mounted, the lever 8 in turn are pivotally suspended on a support 9.
  • the Levers 8 are rotatable on the support 9 about a pivot point 10, being opposed by a positioning drive 11 the carrier 9 can be pivoted.
  • the positioning drive 11 is here as a piston-cylinder arrangement shown. But it can also be designed differently, for example as an electric or magnetic drive.
  • the carrier in turn is in the direction of a double arrow 12 with the help of a not shown Linear actuator movable in the vertical direction, i.e. he can can be moved up and down relative to the winding rolls 5.
  • a holder 13 for a friction roller 14 is arranged on the carrier 9.
  • the friction roller is over a chain 15 or one Belt with a rotary drive 16, for example an electric motor, which is also connected to the carrier 9 is arranged.
  • each section 7a-7h the support roller is at the beginning of the winding process, as shown for example in Fig. 1, operated that the individual sections 7a-7h of the support roller 7 are pressed against the friction roller 14 with a force that is practically slip-free Frictional engagement between the friction roller 14 and the sections 7a-7h of the platen roller 7 causes. then the carrier 9 is lowered so far that the support roller 7 rests on the winding rollers 5 and this with a certain, definable and possibly also adjustable Press force into the changing bed 2.
  • the friction roller lies 14 so on the sections 7a-7h that an almost Slip-free drive of sections 7a-7h guaranteed is. But this is also all sections 7a-7h the support roller 7 rotatably coupled together. It only one drive is required to power all To drive sections 7a-7h of the platen roller 7.
  • FIG. 2a now shows the device 1 at a time, where the winding is more advanced.
  • the The diameter of the winding rolls 5 has increased. Accordingly, the carrier 9 has moved upward Service.
  • the carrier 9 has a transmitter 17 for a sensor 18. If the encoder 17 is in agreement stands with the sensor 18, as an example in FIG. 2a shown, then the winding rollers 5 have one Diameter at which an additional drive torque about the platen roller 7 is no longer required.
  • Fig. 2b the winding rolls 5a-5d also different diameters at this time, the differences here are exaggerated are shown.
  • the Positioning drive 11 actuated and lever 8 clockwise pivoted about the pivot point 10 so that the individual sections 7a-7h of the platen roller 7 from the Friction roller 14 come free, so no longer driven become. At the same time, however, they are used accordingly greater force against the circumference of the winding rolls 5 pressed.
  • the pivoting movement of the lever 8 can here be synchronized with a stroke of the Carrier 9.
  • the platen roller 7, i.e. the individual sections 7a-7h, are provided with a diameter sensor 40.
  • each sensor is only in Fig. 1b represented by its signal line 40a-40h.
  • the sensor 40 is shown schematically. He points a sensor 41 on the center of the platen roller 7 is connected. This center of the platen roller 7 is essentially always above Center of the winding roller 5, so that the position of the Center of the support roller 7 clear information represents over the diameter of the winding roll 5.
  • the transmitter 41 interacts with a receiver 42.
  • the sensor 41 can be a tap of a potentiometer, the conductor track of which then Sensor 42 forms.
  • the Encoder 41 is formed by a light beam that is on a photosensitive surface 42 with photo sensors meets.
  • Such position sensors are known per se. So you use the platen roller 7, so to speak as a sensing roller for the sensor 40, which is thus able is continuously increasing the diameter of the winding rolls 5 determine, because on each winding roll 5a, 5b, 5c, 5d at least a section 7a, 7c, 7e, 7g, 7h rests.
  • All sensors 40a-40h are equipped with an evaluation device 43 connected, including a comparator contains.
  • the evaluation device 43 now has several Tasks. For one, it is able to build the To continuously record winding rolls 5a, 5b, for example the increase in diameter over time record. Based on such a record, which forms a "log book", it is possible later, too after winding to judge whether the winding roll 5 is error-free or faulty. A mistake can can be seen, for example, in that an increase in diameter done unevenly.
  • the evaluation device 43 is also able to the diameter increases of the individual winding rolls with each other to compare. This has several advantages. To the one is better at irregularities in the construction recognize if you have the appropriate structure of several similarly wound winding rolls 5a-5d with each other compares. On the other hand, it is also possible determine whether the diameter increases are strong in themselves are different. For example, take the diameter a winding roll 5c evenly, the diameter the winding roller 5d, however, does not indicate this is due to a web break. The evaluation device 43 then engages in the drive of the support rollers 3, 4 and shut it down. This can cause major damage avoid after a web tear.
