Definitions

  • the invention relates to a method for wrapping a rolled up web of material, in particular a rolled up web of an elastic material, on a wrapping device.
  • the invention also relates to a wrapping device for carrying out the method.
  • the webs of material are, in particular, plastic films that are produced using the casting process or the blown process.
  • Nonwoven webs from spunbond or meltblown systems are also to be understood under these webs. These webs are wound up on rolls so that they can later be further processed into the end product. During further processing, the rolls are unwound again, if necessary, stretched using a stretching device consisting of several rollers, cut to widths (panels) using a cutting station, and cut-to-length web parts are processed into discrete products. With today's high production speeds, roll changes are very important.
  • Role changes can mean production stoppages, with stopping and restarting the production systems requiring a great deal of effort. Therefore, large rolls with winding diameters of up to four meters are increasingly being produced, which are then wound onto rolls with smaller roll diameters in an offline system, a rewinding device or rewinding machine.
  • This wrapping device which has reached its limits in terms of time. That is why several wrapping devices are often operated in parallel here.
  • Such wrapping devices have a dispenser in which the large rolls are received. The material web is unwound from the large roll, panels are cut and then rewound in smaller rolls on the reel-up.
  • the large rolls often have a mass of up to ten tons and must accordingly be gently accelerated and decelerated, i.e. braked, so that the material web is not damaged.
  • rewinding devices are therefore fixed constant acceleration ramps.
  • acceleration is used below, always referring to both positive and negative acceleration, ie deceleration.
  • a closed material web e.g. a CPP film
  • air layers must be taken into account as a buffer between the individual layers of the material web on the roll, depending on the processed material and its shrinkage behavior.
  • an elastic material is understood to mean a material that has a much higher elasticity than metals or paper and whose shrinkage is not completed immediately after the production of the film and nonwoven web and whose shrinkage behavior must be taken into account when rolling and wrapping .
  • the object of the invention is therefore to provide a method for wrapping a rolled up web of an elastic material on a wrapping device with which the wrapping times can be reduced compared to the prior art.
  • Another object of the invention is to provide an apparatus for carrying out the method.
  • the first object of the invention is achieved with a method according to independent claim 1.
  • Advantageous further developments of the method emerge from claims 2 to 14.
  • the second object of the invention is achieved with a device according to the independent claim 15.
  • the inventive method for wrapping a rolled up web of an elastic material on a wrapping device with a dispenser and a winder, wherein the web is wrapped from a large roll rolled on the dispenser with a diameter D onto a utility roll to be wound on the winder and wherein the dispenser and / or the winder has an actuator, is characterized in that the diameter D of the large roll on the winder and / or the diameter d of the utility roll on the winder is continuously determined during the wrapping process and the performance of an actuator is continuously adjusted using this determined parameter.
  • the term "continuously determining” or “continuously adapting” is to be understood here not only as an actual continuous, i.e. constant determination or adjustment, but also one at discrete time intervals, with the determination taking place several times via the wrapping process.
  • At least one device of the dispenser and retractor has an actuator, for example in the form of a motor or a belt or chain drive for the drive.
  • An actuator in the form of a belt drive can also be attached to a roller in any position.
  • an actuator with self-propelled support rollers can represent both a roller, either alone or in combination with other rollers, and also operate the rolling up with the aid of motor power.
  • a lay-on roller can represent a further form of an actuator.
  • Lay-on rollers are usually placed on a roll and serve, for example, as an additional one self-propelled actuator. They can act on the roller alone or in combination with several other rollers, for example carrier rollers.
  • the actuator can also apply a braking torque to the unwinder or the winder, for example in order to control the tension of the web of material during the wrapping process, in particular at the start and end of a wrapping process.
  • the web of material can also be driven via a roller which is arranged between the unwinder and the winder.
  • the material web is guided over this roller, the roller being able to have an actuator which can apply a torque to the roller.
  • Part of the web wraps around the roller.
  • the roller can also be part of a roller arrangement with a plurality of rollers, for example a pair of rollers.
  • the diameter D of the large roll rolled up on the winder and / or the diameter d of the utility roll to be rolled up on the winder is measured continuously by means of an optical sensor.
  • an optical sensor can, for example, be a camera with a corresponding Be an image evaluation device.
  • Movable light barriers, for example, are also conceivable as optical sensors. Optical sensors work quickly and reliably.
  • the diameter D of the large roll rolled up on the unwinder and / or the diameter d of the utility roll to be rolled up on the winder is continuously measured by means of an electromechanical sensor.
  • an electromechanical sensor can be designed as a button, for example. Electromechanical sensors are usually cheaper than optical sensors.
  • the diameter D of the large roll rolled up on the unwinder and / or the diameter d of the utility roll to be rolled up on the winder is continuously measured by means of an electronic sensor.
  • the diameter D of the large roll rolled up on the winder and / or the diameter d of the utility roll to be rolled up on the winder is continuously determined by means of calculation.
  • the diameter or the diameter can easily be calculated via the take-off speed. If input parameters are used for the calculation that are already available in the process, no further sensors need to be used to control the performance of an actuator.
  • Windows can be specified for all nominal values, whereby the limit values can be calculated values or values known from experience.
  • the diameter D of the large roll rolled up on the winder and / or the diameter d of the utility roll to be rolled up on the winder is determined by means of the permanently weighed roll weight.
  • the diameter D of the large roll rolled up on the unwinder and / or the diameter d of the utility roll to be rolled up on the winder is determined via the continuously measured speed of the material web on one of the rolls of the winder and the unwinder, preferably on all rolls.
  • the diameter D of the large roll rolled up on the winder and / or the diameter d of the utility roll to be rolled up on the winder is calculated from the continuously measured speed of the web and the rotational speeds of the rolls of the winder and winder.
  • the diameter D of the large roll rolled up on the unwinder and / or the diameter d of the utility roll to be rolled up on the winder is determined by means of the cumulative layer thicknesses of the web layers on one of the rolls of the winder and unwinder, preferably on all rolls.
  • the layer thickness of a material web layer can be measured, for example, by means of an optical sensor.
  • control unit controls one actuator, preferably all actuators.
  • an actuator is controlled manually.
  • the wrapping device has a roller, the roller preferably being arranged between the unwinder and the winder and being vertically displaceable, the web of material being guided over the roller.
  • the drive of the web can additionally or alternatively take place via the roller.
  • the material web is guided over this roller, the roller being able to have an actuator which can apply a torque to the roller.
  • Part of the web wraps around the roller.
  • the roller can also be part of a roller arrangement with a plurality of rollers, for example a pair of rollers.

  • the web 100 is partially deflected and / or also stretched over several rollers 400.
  • the material web 100 is also guided through a cutting station, which is not discussed further, which can, if necessary, carry out different cutting processes on the material web 100.
