Definitions

  • the invention relates to a method for simultaneous Winding of several partial webs, which consist of a material web to be cut in a winding position group arranged partial web rolls. Further concerns the invention a device for simultaneous Winding of several partial webs to partial web rolls with at least one winding position group in which several Partial web rolls are arranged.
  • Paper webs are nowadays used with relatively large widths, which can be up to 10 m, produced. 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, whose width is in the range of 0.5 to 3,8 m can lie. These sublanes then become too Ambibahn- or wound rolls wound up, the one Have final diameter in the range of 0.5 to 2.5 m.
  • Such bobbins are then packed and to the Consumers, for example, a printer, delivered.
  • the partial web rolls After winding, the partial web rolls are ejected and packed. In most cases, it will still be there certain parameters, such as weight or diameter, detected.
  • WO 97/47544 A1 shows a control method during winding.
  • the carrier can help with a drive in its altitude, so its relative Position to support rollers, to be changed.
  • On the carrier is a cylinder arranged on the swingarm acts to tighten the pinch roller on the peripheral surface of the To hold partial web rolls.
  • a sensor is provided to continuously removing a pinch roller from the To measure wearers. This measured distance is in compared to a comparator with a setpoint. If If there is a deviation, the drive is actuated, to raise or lower the carrier.
  • FR 2 524 449 A shows a winding machine in which a Web is wound on a winding roll, the is carried by two driven carrier rollers. On the top of the winding roll loads a pressure roller their own weight, but also with the weight of their above arranged bracket. The pressure roller is with raised winding roll diameter.
  • a control device When lifting a tap of a potentiometer is adjusted. The voltage value tapped on the potentiometer is used a control device as an input signal. This input signal is directly proportional to the path of the pressure roller and thus the increasing winding roll diameter.
  • the control device controls a valve so that a drive cylinder, the pressure roller in the can shift right position.
  • the invention is based on the object, the control options to improve when winding.
  • This object is achieved in a method of the aforementioned Art solved by at least one predetermined Parameters of each individual sub-train role continuously is determined, the parameters of the sub-web roles be continuously compared.
  • the winding interrupted becomes when between data of sub-train roles Differences result that have a predetermined value exceed. Even if several partial webs from the same material web are cut, are smaller Differences practically unavoidable. This is in a paper web, for example, because the Headbox crosswise to the direction not absolutely constant can hold. Usually, the material web slightly thicker in the middle than at the edges. Accordingly, for example, the weight will and the diameter of a partial web roll coming out of Middle of the material web is cut, enlarge more as the weight of partial web rolls from the Edge. Nevertheless, one can with a certain reliability predict how big differences can be, without indicating an error. A relatively safe Indication for the existence of a mistake is above all then given if the parameters of partial web roles change while getting the same parameters from others Do not change partial web roles.
  • the data is acquired only from a predetermined Diameter of the partial web rolls.
  • errors for example Web breaks, usually only from a certain Diameter occur while smaller in size Roll diameters are relatively rare.
  • the diameters of the individual are used Subtrack roles as data.
  • the diameter of the partial web rolls can be detected relatively easily, for example with a feeler roller.
  • the effort for the Recording the data of the sub-web roles remains so small.
  • the object is in a device of the aforementioned Art solved by each sub-train role at least one sensor is assigned, the consecutive at least one predetermined parameter of this partial web roll determined, with the sensors with a comparator connected, the parameters of the sub-web roles continuously compares with each other and a part of a drive control device forms.
  • the senor is designed as a diameter sensor.
  • the diameter of the partial web roll is a relative one easy-to-capture parameter.
  • the diameter increase over time is at constant Wikkel niethhelial senor senor senor senor senor senor senor senor senor senor senor senor senor senor senor.
  • the diameter of the partial web roll is a relative one easy-to-capture parameter.
  • the diameter increase over time is at constant Wikkel niethresis, so that deviations easily recognized by this growth.
  • the senor is with a loading roller coupled, which acts as a tracking roller.
  • a loading roller coupled, which acts as a tracking roller.
  • Such Loading roller is in many winding devices in any case, especially at the beginning of a Wikkelvorgangs the forming partial web role against a Support or contact roller or in the winding bed too Press, at the beginning of the winding process a high To generate winding hardness.
  • the loading roller is in the axial direction divided into segments, the segments by a coupling device can be coupled and a common Have rotational drive.
  • This can be done at the beginning the winding process, where a diameter detection not yet necessary, the load role as an additional means to use a torque in to enter the forming partial web rolls. This Further torque can increase the winding hardness be used.
  • Fig. 1 shows in Fig. 1a is a schematic side view and in Fig. 1b is a front view of a Rollenwikkel Anlagen 1.
  • the roll winding device 1 has a winding bed 2, which by two support rollers 3, 4th is formed.
  • the bobbins 5a-5d are due to the rotation of the support rollers 3, 4 or at least one of the two support rollers 3, 4 driven and thereby pull a non-illustrated Material web previously cut into partial webs has been on a roll core 6.
  • the next to each other lying winding rollers 5a-5d are also called Wikkelrollenanssen designated.
  • a support roller. 7 on On the winding rollers 5a-5d is a support roller. 7 on. As can be seen from Fig. 1b, the platen roller 7 in the axial direction in a variety of sections 7a-7h divided. Each section 7a-7h is at two Levers 8 rotatably mounted, the lever 8 turn are suspended pivotally on a support 9.
  • the Levers 8 are rotatable on the carrier 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 he can also be trained 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 Hubantriebs in the vertical direction movable, i. he can moved up and down relative to the winding rollers 5.
  • a holder 13 for a friction roller 14 is arranged on the carrier 9, a holder 13 for a friction roller 14 is arranged.
  • the friction roller is about a chain 15 or a 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, so actuated, that the individual sections 7a-7h of the platen roller 7 are pressed against the friction roller 14 and that with a force that is practically slip-free Friction 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 platen roller 7 rests on the winding rollers 5 and this with a certain, specifiable and possibly also adjustable Force in the winding bed 2 presses.
  • the friction roller is located 14 so at the sections 7a-7h that an almost slip-free drive of sections 7a-7h guaranteed is. But so are all sections 7a-7h the support roller 7 rotatably coupled together. It Only a single drive is necessary to all To drive sections 7a-7h of the platen roller 7.
  • FIG. 2a now shows the device 1 at a time, where the winding has progressed further.
  • the carrier 9 has moved further upwards Service.
  • the carrier 9 has a transmitter 17 for a sensor 18. If the encoder 17 in accordance with the sensor 18 is, as in Fig. 2a by way of example represented, then the winding rollers 5 a Diameter at which an additional drive torque over the platen roller 7 is no longer required.
  • Fig. 2b have the bobbins 5a-5d at this time also different diameters, the differences here are exaggeratedly big are shown.
  • the Positioning drive 11 is actuated and the lever 8 in a clockwise direction pivoted about the pivot point 10, so that the individual sections 7a-7h of the platen roller 7 of the Friction roller 14 free, so no longer driven become. At the same time they will be with a corresponding greater force against the circumference of the bobbins 5 pressed.
  • the pivoting movement of the lever 8 can in this case be synchronized with a lifting movement of the Carrier 9.
  • the platen roller 7, i. the individual sections 7a-7h, are provided with a diameter sensor 40.
  • each sensor is only represented by its signal line 40a-40h.
  • the sensor 40 is shown schematically. He points an encoder 41 which is connected to the center of the platen roller 7 is connected. This center of the platen roller 7 is essentially always above the Center of the winding roll 5, so that the position of the Center point of the platen roller 7 a clear information represents over the diameter of the winding roll 5.
  • the encoder 41 cooperates with a receiver 42. For example, the encoder 41 a tap a potentiometer, whose trace then the Transducer 42 forms.
  • the Encoder 41 is formed by a light beam, the on a photosensitive surface 42 with photosensors 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, capable of doing so is, continuously the diameter of the winding rollers 5 to determine, since on each winding roll 5a, 5b, 5c, 5d at least a portion 7a, 7c, 7e, 7g, 7h rests.
  • All sensors 40a-40h are equipped with an evaluation device 43 connected, among other things, a comparator contains.
  • the evaluation device 43 now has several Tasks. For one, she is able to build the Bobbins 5a, 5b, continuously log, for example, the diameter increase over time record. Based on such a record, which makes a "logbook", it is possible later, too after winding to judge whether the winding roll 5 faultless or faulty. An error can For example, be characterized by an increase in diameter unevenly done.
  • the evaluation device 43 is also able to the diameter increases of each bobbins with each other to compare. This has several advantages. To the One can be irregularities in the structure better recognize, if one has the appropriate structure of several similarly wound bobbins 5a-5d with each other compares. On the other hand, it is also possible determine if the diameter gains per se are strong are different. Take, for example, the diameter a winding roll 5c evenly, the diameter the winding roll 5d, however, not, then indicates this on a web break. The evaluation device 43 then engages in the drive of the support rollers 3, 4 a and put these down. This can be major damage avoid after a paper web break.
