Definitions

  • the invention relates to a marking unit for marking a means of a Winding device on a winding core aufwickelbaren material web and a corresponding marking method.
  • Roll winder in which the winding core with the already wound material web, this is referred to as a role, with one or a plurality of pressure rollers is in contact, wherein in each case between roller and Anpresswalze a nip is formed.
  • a disadvantage of the known mechanical method is that the manual application the frontal line (marking) for the performer by the proximity to the itself rotating role is dangerous. Furthermore, the reproducibility of the manual Marking strongly depends on the expediency of the performer. In addition, the manual procedures are not prophylactic applicable, since these are always in the Following the obtained winding quality can be determined.
  • a marking unit comprising a writing device for marking a material web, which can be wound on a winding core by means of a winding device and wherein the Marking device has a signal generator, with the winding core of Winding device is in operative connection, so that depends on the signal generator depending on the Rotation of the winding core, a clock signal can be output, based on the Writing device sets a mark on the web.
  • the signal generator to the Write device outputs a clock signal.
  • the signal transmitter is mounted such that at each completed revolution the winding core, a clock signal is output. But it is also conceivable that a Clock signal every half or quarter turn of the center of rotation of the winding core is issued.
  • the signal generator is arranged in the center of rotation of the winding core.
  • the writing device is such to Material web arranged that the marking on the front side of the material web can be applied.
  • the Winding device has a pressure roller which forms a nip with the roller, and that the writing device in relation to the direction of movement of the material web in front of the nip is arranged.
  • the writing device go into by the Marks formed pattern, for example. J-line, both Bruzug baseungen on the Material web as well as, for example, force effects of the nip on the web.
  • the Writing device is arranged such that through this already wound Material web is markable, i. the writing device is related to Direction of movement of the web arranged behind the nip. Behind the nip has become the already acting before the nip on the web train already partially reduced.
  • the shape of this pattern for example the J-line, thus becomes in another Determined ratio of the web train, as in marking the material web in front of the nip.
  • Another embodiment of the invention is a writing device in the area of Arranged nips, whereby the shape of the pattern, for example, the J-line, turn in one other measure of the train and the force effect is influenced in the Nipp than the previously mentioned "application locations".
  • the Writing device far away from the winding device eg. At the end of the Drying section arranged.
  • the factors mentioned above go different in the shape of the formed pattern, for example, the J-line, a.
  • each Write device generates this in parallel with the other writing devices own pattern, eg J-line.
  • J-line the other writing devices own pattern
  • J lines these may, for example, have different colors.
  • a writing device is arranged in front of the nip, go here Web tension changes and, for example, force of the nip on the web into the mold of the pattern, for example the J-line, and a writing device arranged after the nip,
  • the train moves in another Ratio, so may from the difference of the two of the writing devices in front of and behind the nip generated pattern, for example.
  • J-lines inferences Web tension changes are pulled around the pressure roller.
  • the Marking unit To set the markers set by the writing unit already during operation, i. judging in the rotating state of the role, it makes sense if the Marking unit has a sensor unit, which the of the writing unit applied and on the role of a pattern forming markers detected.
  • the Markers may hereby form a pattern in the form of a J-line.
  • a sensor unit For example, an optical sensor such as a camera or a camera system comes into consideration.
  • the sensor unit For analyzing the information obtained by the sensor unit, it is further makes sense if the sensor unit is connected to an evaluation unit, wherein of the Sensor unit based on the detected marks sensor signals to the Evaluation unit can be output.
  • evaluation unit for the assessment of the sensor unit detected pattern, for example J-lines, these with Referenzmustem, for example. Reference J-lines, compares.
  • a particularly preferred embodiment of the invention therefore provides the evaluation unit compares the received sensor signals with reference signals and outputs evaluation signals based thereon.
  • both those may be considered that are particularly "good” or especially "bad” J-lines represent.
  • J-lines are drawn directly to certain winding defects.
  • control for example, at "degeneration" of the J-line and regulate to be able to act on the winding and thus already it is useful to be able to correct suggestive winding errors early on Evaluation unit is connected to a control unit, by which parameters the Winding device and / or one or more of the winding device upstream Sections of the web-processing machine are controllable, being used by the Evaluation unit to the control unit evaluation signals can be output.
  • parameters are, for example, winding hardness of the roll and / or web tension and / or Force effect (line force) of the nip roll and pressure roller into consideration.
  • the control unit in turn outputs based on these evaluation signals, i. for example, depending on the shape of the J-lines or to obtain a desired shape of the J-lines, Control signals to one or more sections of the web-processing machine and to the winding device, which controlled important parameters for the winding process become.
  • FIG. 1 shows a marking unit 1 in conjunction with a winding device 10.
  • the marking unit 1 has a first writing device 2, a second one Writing device 3, a signal generator 4 and a sensor unit in the form of a camera. 5 on.
  • the winding device 10 has a winding core in the form of a spool s 11 and a Pressure roller 12 on.
  • the roller 13 and the pressure roller 12 become a line force to form one generating nips 16 pressed against each other.
  • the writing device 2 is in relation to the direction of movement 15 of the fibrous web 20 before the nip 16 arranged.
  • the writing device 3 is in relation to the movement direction 15th the fibrous web 20 behind the nip 16 arranged.
  • the signal generator 4 is arranged in the center of rotation 14 of the main cylinder 11 and is in present embodiment at every full revolution of the spool 11 a Clock signal 6 'to a control unit 7, which in turn at the same time a clock signal 6 "to both write devices 2, 3 and the camera 5 outputs.
  • the signal generated by the signal generator 4 clock signal 6 'first to a Control unit 7 passed and from this is a clock signal 6 "to the two Writing devices 2,3 and the camera 5 distributed.
  • the Signal generator 4 directly to the writing devices 2,3 and the camera 5 clock signals. 6 outputs.
  • the markers 21 and thus the J-line 23 are in this case of the Writing device 2 generated.
  • the J-lines 23 and 24 are detected by the camera 5, which on the end face of the Roller 13 is directed.
  • the camera 5 inputs to an evaluation unit 8 connected to it Sensor signal 9 off.
  • the sensor signal 9 is evaluated in the evaluation unit 8 by this, for example, with reference signals 25 of "good” and / or "bad” J lines is compared.
  • Based on the evaluation o.g. Sensor 9 and reference signals 25 are the Evaluation unit 8 evaluating signals 17 to a control unit 18 connected to it, which in turn control signals 19 to the winding device 10 and / or at the Winding device upstream sections of the web-processing machine for Influencing the winding parameters outputs.
  • the marking unit described and the described Marking method not for use in the winding of fibrous webs limited. Rather, the marking unit according to the invention and the Inventive marking method in the winding of all types of web-shaped Materials such as. Foils, sheets and the like. Applicable.
