Definitions

  • the present invention relates to a method for providing a web-related material web dataset of a material web produced in a rolling mill for a rolling mill independent processing device in which the material produced in the rolling mill and wound to a rolling mill coiled from a processing coil, which consists of a partial length of the material web produced in the rolling mill is formed, unwound and further processed, wherein during the production of the material web in the rolling mill in dependence on a Brulteilenkoordinate X a material web parameter Y detected by a parameter detecting means and a Brubahnenkoordinaten X and associated material web parameters Y formed material web record is stored in a storage medium in which an am Processing coil missing web segment determined and one of the length and the relative arrangement of the web segment in the rolling mill coil corresponding track length correction value is determined, and the material web dataset of the rolling mill coil taking into account of the path length correction value is converted into a material web data record of the processing coil.
  • the material web is wound into a coil, referred to below as a rolling stock coil, for further processing to a suitable processing device, for example a cutting device for longitudinal division of the material web into a plurality of material webs with a defined width, for example as starting material for the production of foil bags serve, pass.
  • a suitable processing device for example a cutting device for longitudinal division of the material web into a plurality of material webs with a defined width, for example as starting material for the production of foil bags serve, pass.
  • the present invention is therefore based on the object to provide a method for providing a web-related material web set of a material web produced in a rolling mill, which allows the use of the material web data set in a mill independent processing device.
  • the inventive method has the features of claim 1.
  • a comparison of the further processing coil with the rolling mill coil takes place to determine the missing material web segment.
  • the determination of the missing material web segment with respect to its relative arrangement and its length takes place directly on the rolling mill coil, ie without an unwinding process of the rolling-mill coil which presupposes the determination of the missing material web segment.
  • the determination of the missing material web segment therefore requires no additional handling effort, in particular, the missing material web segment must not be measured to determine its length.
  • the comparison takes place by means of an image-processing method, wherein by means of an imaging process, a first image of a formed on an end surface of the rolling mill coil winding mirror with a second image of a formed on an end surface of the processing coil winding mirror.
  • the storage of the corrected material web dataset takes place in a storage medium that is locally independent of the rolling mill, access to the material web dataset is made possible without requiring a direct physical or information-technical connection to the rolling mill. In particular, in this case there is no need to install the latter at the location of the rolling mill as a prerequisite for the use of the material web dataset during operation of a processing device.
  • the storage medium for storing the corrected material web data record is installed on a network server so that, in particular when the network server is configured as a cloud server, multiuser access to the network server can take place via an internet connection and a fundamental one Unlimited number of users can retrieve the web information from the network server.
  • a material web parameter to be detected during processing of the material web of the processing coil in the processing device as a function of the web length coordinate by means of a parameter detector device and a material web data record formed from web length coordinates and material web parameters stored in a storage medium and used to define operating parameters for the control of the rolling mill.
  • material web parameters determined during further processing in the processing device that deviate from corresponding set specifications of the further processor are used for defining and / or optimizing operating parameters of the rolling mill in order to be able to meet the target specifications of the further processor by corresponding change of the operating parameters.
  • the flatness and / or the surface quality and / or the thickness can be determined in a processing device designed as a cutting device, and in an operating parameter data set for statistical process optimization fed to the rolling mill.
  • the flatness of the material web is exemplified here for quality-determining parameters in which the knowledge and assignment of the strip length coordinate is necessary for optimizing linked production processes.
  • other parameters such as thickness, hardness or residual oil content of the web-like material can be detected in downstream processes and used with the knowledge of cut-off belt segments to optimize upstream manufacturing processes.
  • the storage medium for storing the material web data record and / or the operating parameter data set is installed on a network server so that access to the operating parameters of the rolling mill is not only independent of the local association between the processing device and the rolling mill can, but also from any number of processors.
  • Fig. 1 shows a rolling mill 10 during the production of a guided through a nip 11 of the rolling mill 10 material web 12, which is moved in a hot or cold rolling process either in reversing between two winders 13, 14 and this is alternately wound on 13, 14 and unwound or in a one-way operation in several rolling operations each rolled from a scheduler 13 to a winder 14 and transported to the unwinder for the Folwalalzvorgang until the desired web thickness is reached.
  • the length-related detection of quality and process-relevant material web parameters is continuously carried out, for example, the flatness of the flatness is recorded by means of a flatness measuring device.
  • the tape length changes due to the reduction in thickness and possibly cut tape segments.
  • a rolling-mill coil 16 wound in the rolling mill 10 is removed, which is subsequently to a processing device 17, ie
  • a processing device 17 for example, a device for longitudinal division of the web 12 into a plurality of webs 12a, 12b of defined width, which are used for example as a starting material for the production of foil bags.
  • a corresponding material web segment 26 is separated from the rolling mill coil 16 before further processing of the material web 12 in the processing device 17. Therefore, there is a, as in particular from Fig. 2 A reduction of the material web to a web segment 26 is also carried out at material withdrawals between the various passes in the rolling mill or in a fault within a corresponding reduction of the web 12 and circumference reduction of the rolling mill Stitch. Accordingly, it then comes to form a processing coil 18, which provided for further processing in the processing device 17 and in a winder 36 of the processing device 17, as in Fig. 1 shown, is recorded.
  • the flatness measuring device 15 of the rolling mill 10 determines, depending on a web length coordinate X, the flatness data Y associated with each web length coordinate so that a web data record 24 characterizing the web 12 is formed from the web length coordinates X and the flatness data Y, which data are transmitted to a network server 25 and stored in the storage medium the network server 25 is stored.
  • the access to the storage medium of the network server 25 can be done for example via a data line or via an Internet connection.
  • the network server may be both a local server in a local area network or wide area network and a virtual server in a data cloud, that is, an internet server.
  • Fig. 2 apparent causes the separation of the material web start segment 26 from the rolling mill coil 16 a circumferential reduction of the rolling mill coil 16, wherein an inner part of the rolling mill coil 16 formed between the parting lines 27, 28 forms the processing coil 17.
  • Fig. 2 shows, results due to the winding process in the formation of the rolling mill coil 16 for each rolling mill 16 individual winding mirror 29, which is determined in particular by operating parameters in the production of the material web 12 in the rolling mill 10 and material parameters of the web 12.
  • the winding mirror 29 is roughly comparable to a fingerprint, wherein the course and the topography of a material web longitudinal edge 30 at the end face of the rolling mill coil 16 forms the winding mirror 29 so that an image generated in an imaging process of the winding mirror 29 as an image file identification document for identifying a from a material web 12 produced in a rolling mill 10 is individually trained rolling coil 16 represents.
  • FIG. 2 clearly demonstrates that the processing coil 18, which has a winding mirror 39, is identical in its identity to the rolling mill 16.
  • the length of the separated material web segment 26 can now easily be determined on the basis of the number of turns of the separated material web starting segment 26 without actual length measurement and position determination being carried out.
  • the known length of the material web starting segment 26 now makes it possible to convert the material web data record 24 of the rolling stock coil 16 stored in the storage medium of the network server 25 into a material web data record 35 by means of a web length correction value, without carrying out a new flatness measurement on the material web 12 of the processing coil 17.
  • the material web data record 35 is also available via the processing device 17 to the network server 25 access to the processed in the processing device 17 web 12, so that is statements about the web length-related flatness of the guided through the processing device web 12 due to a rolling mill 10 performed flatness measurement can be made.
  • the networking of the rolling mill 10 with the further processing device via the network server 25 makes possible the use of material web data determined in the rolling mill 10, ie in the present case the flatness data, independent of the local assignment of the rolling mill 10 to the processing device 17.
  • a direct data connection between the rolling mill 10 and the processing device 17 may be provided.
