Definitions

  • the invention relates to a method for winding a material web onto a winding tube to form a winding roll in winding machines after longitudinal cutting of a material web unwound from a mother roll, the mother roll and the winding roll being driven.
  • the invention also relates to a device for winding a material web onto a winding tube to form a winding roll in winding machines after longitudinal cutting of a material web unwound from a parent roll, comprising two support rollers arranged axially parallel to one another for supporting the winding roll, forming two winding gaps, the material web in the first winding gap is guided to the winding roll with at least partial wrapping around the first support roller and the second support roller downstream of the first support roller in the material web running direction is free from being wrapped around by the material web and the mother roller and the first support roller are each assigned a drive with a control unit and between the mother roller and the first At least one sensor that detects the web tension is arranged on the support roller to carry out the method.
  • the invention is explained below in connection with the treatment of a paper web. However, it can also be used for other railways that have to be handled in a similar way. These include, but are not limited to, sheets of cardboard, cardboard, plastic or metal foil,
  • Paper webs are produced in relatively large widths of up to over 11 m in a paper machine. Production is virtually endless.
  • the direction of movement of the goods on the paper machine defines the longitudinal direction for all machines and equipment in the paper factory and, in the horizontal plane perpendicular to it, the transverse direction.
  • the full width of the paper web produced is wound onto a winding core.
  • This winding core is cyclical, usually while it is running production, replaced.
  • the web-wide winding roll created in this way is usually referred to as a mother roll or solid reel.
  • the paper web wound on a mother roll must be cut into several parallel partial webs, the widths of which are suitable for the respective later user. These widths can vary greatly from case to case, so that the paper web is usually divided according to an individually definable cutting pattern.
  • the partial webs are then wound into winding rolls, which are called partial web or finished rolls and which are issued together as a so-called roll roll.
  • the pattern can be changed from roll to roll to roll.
  • the longitudinal cutting and winding is expediently carried out in a single machine, which is then often referred to as a winder.
  • winding devices described above i.e. those for producing mother rolls as well as those for producing partial web or finished rolls, have in common that the web to be wound up to form a winding roll forms a winding gap with at least one winding roller on which it is supported or on which it is supported lies against or rests on it and is accordingly referred to as a support or support roller.
  • These winding rollers which are in direct contact with the winding rolls being formed, therefore also represent the directly acting tools by means of which the winding quality can be influenced.
  • While the main drive of the winding roll is speed-controlled and determines the speed of the winder, the drive of the mother roll is torque-controlled with superimposed web tension control.
  • the parent roll is relatively inhomogeneous in terms of specific weight, as the core is usually wound harder than the outside. Therefore, the calculation of the flywheel and consequently the control of the drive torque during acceleration and braking is very inaccurate.
  • Such machines are described, for example, in DE 30 30 798 A1 as well as the DE 10 2010 039 007 A1 .
  • the object of the invention is to improve the winding results in slitting machines.
  • the object was achieved in that, depending on the operating state, the mother roll or the winding rolls are driven in such a way that the web tension is at a predetermined interval.
  • the drive of the winding rolls should take over the regulation of the web tension when accelerating and braking unwinding.
  • the drive of the parent roll determines the system speed.
  • the drive of the mother roll should take over the regulation of the web tension, as has been usual and proven so far.
  • the drive of the winding rolls determines the system speed in this operating state.
  • the parent roll should be driven at times in a speed-controlled/regulated manner and at times in a torque-controlled/regulated manner.
  • the mother roll should be speed-controlled and regulated during crawling speed, when accelerating or braking during unwinding Production speed of unwinding can be driven in a torque-controlled/regulated manner.
  • the winding roll should at least predominantly be driven in a speed-controlled/regulated manner.
  • At least one sensor detecting the web tension is arranged between the mother roll and the first support roller, which sensor can be connected by the machine control to the control unit of the drive of the mother roller or the control unit of the drive of the first support roller, depending on the operating state.
  • the preferred embodiment of a roll winding device according to the invention shown in the figure is realized in connection with a roll cutting device designed as a support roll winding device.
  • Essential components of this roll cutting device are an unwinding device 15, in which the paper web 1, which corresponds in width essentially to the working width of a paper machine upstream of the roll cutting device and not shown here, is pulled off from a mother roll 4, a cutting section 17 in which the paper web 1 is used Generation of partial webs in selectable width formats is divided lengthways according to their running direction and a winding arrangement 16 located in the area of their winding.
  • the mother roll 4 is assigned its own drive 8 with a control unit.
  • the cutting section 17 includes, as essential components, mostly disc-shaped cutting devices, which are shown here in the form of upper knives 18 and lower knives 19 that act on one another.
  • this area is delimited by deflection rollers 20 in the example shown.
  • the at least one winding roll 3 to be wound and the support roller 21 form essential elements of the winding arrangement 16. Although only the end face of a single winding roll 3 is visible in the figure, it is assumed here that in the Image plane extending Y direction additional winding rollers 3 are located behind the winding roller 3 shown, in the winding bed formed from the two support rollers 5,6.
  • the core of the winding rolls 3 formed in the course of the winding process each consists of a winding sleeve 2, to which the beginning of a finite section of a partial web of the material web 1 is connected and then spanned by continuous winding to form so-called winding layers.
  • the two support rollers 5, 6 arranged axially parallel to one another serve to support the winding roll 3, forming two winding gaps 11, 12, the material web 1 being guided to the winding roll 3 in the first winding gap 11, partially wrapping around the first support roller 5 and the first support roller 5
  • the second support roller 6 arranged downstream in the web running direction 7 is free from being wrapped around by the material web 1.
  • the second support roller 6, which forms the second winding gap 12 in the direction of rotation of the winding roller 3, is always mechanically coupled to the first support roller 5 via the winding roller 3.
  • Both support rollers 5,6 are each assigned a drive 9,10 with a control unit.
  • the support rollers 5,6 can have an elastic bearing. Likewise, at least one of the two support rollers 5, 6 can have a coating or casing that is effective on the material web 1.
  • the web tension of the material web 1 between unwinding and winding is essentially constant so that no damage to the material web 1 occurs.
  • Winding errors that can be attributed to a non-uniform web tension can, for example, be reflected in tears or folds and can also cause corresponding consequential damage.
  • relatively large changes in the web tension can occur, particularly during acceleration and braking processes.
  • the drive 8 of the mother roller 4 and the drives 9, 10 of the support rollers 5, 6 are connected to the machine control 14 via their respective control unit.
  • the web tension of the material web 1 between the mother roll 4 and the first support roller 5 is detected by a sensor 13 and transmitted to the machine unit 14.
  • a control system here refers to the entirety of the functional components required to carry out control and regulation tasks and their connections. This includes control devices, regulators, devices for recording actual values, disturbance variables and actuating devices as well as their connections to one another.
  • the machine control 14 is intended to ensure that, depending on the operating state, the drive 8 of the mother roll 4 or the drive 9,10 of the winding rolls 3 is carried out in such a way that the web tension is within a predetermined interval.
  • the senor 13 is connected by the machine control 14, depending on the operating state, to the control unit of the drive 8 of the mother roll 4 or the control unit of the drive 9 of the first support roller 5 for a higher-level web tension control.
  • the drive 8 of the mother roll 4 is torque-controlled with a higher-level web tension control, so that the web tension is within a predetermined interval.
  • the drive 9 of the first support roller 5 is only speed-controlled.
  • the drive 9 of the first support roller 5 is speed-controlled with a higher-level web tension control, so that the web tension is within a predetermined interval.
  • the drive 8 of the mother roller 4 is only speed-controlled.
  • the relevant flywheel mass is essentially determined by the winding roll 3, which is significantly lighter than the parent roll 4, which minimizes the fluctuations in the web tension.
