Definitions
- the invention relates to a method for automated guidance of a straightening process for a target, such as sheets, strips, profiles, pipes and in particular for a wire or multi-wire straightening material in a straightening machine or in a straightening machine with at least one straightening roller adjustable by an actuator.
- roller straighteners or straighteners are used.
- the size of the Alternating bends on the jobs of the straightening roles based on the experience of the Straightener set more or less intuitively.
- the change in Settings of the individual straightening roles are made under visual contact with the leaking straightening material until a satisfactory straightness is achieved.
- DE 195 03 850 C1 describes a non-rotating straightening device for Bending machines with an integrated measuring device are known.
- the straightener is behind at least one straightening unit in the direction of flow of the material arranged at least one material bending measuring device in which at least one measuring section for a predetermined length Material section is provided, along the measuring section at least one the extent of the bend and the sense of the bend determining mechanical and / or electronic and / or optical Scanning device is arranged, with the scanning device signals representing measured bending of the material section are generated with which an actuator is adjusted accordingly.
- the measuring device of the known straightening apparatus works according to the Principle of determining curvature using the three-point method, the only for cut to length or for shutdown, d. H. if that Target free of external forces and moments, neglecting gravity is, gives correct results. Is the curvature of the leaking material not constant over the length of the measuring section, the measurement result is also influenced by the length of the measuring section.
- the straightening process becomes necessary when the straightening good is stopped interrupted. Stopping and restarting leads to influencing the result of the curvature measurements and changes, that affect the quality of the straightening process. So that is Check the setting only by stopping the Straighteners possible, d. H. continuous monitoring and Regulation with running straightening goods or during straightening is not possible.
- the object of the invention is to provide a method. practically one instantaneous, automatic adjustment of the setting of at least one Straightening roll of straightening apparatus or straightening machine on continuously measured data of the respective target material without stopping the Straightening process enables.
- the invention is summarized, including more advantageous Developments based on the principle in a preparatory phase Straightening process to be automated using mathematical-physical To model laws, a Create simulation program and with the simulation program a variation calculation with variation of the product data, in particular the material properties and / or the dimensions of the target perform.
- This phase can be considered "offline”.
- Based of continuously measured product and / or process data during the ongoing straightening process, d. H. done without stopping the target material including the results of the variation calculation "online” very much quickly the necessary to achieve the desired product quality Adjustment of the straightener or straightener.
- the change in Attitude is objective and determined.
- the measured product and / or Process data are also used to create the model as well as to check the simulation program and if necessary to change. Instead of subjective experience, the sense of proportion of the the straightening machine or the straightening machine operator. kick the Objectivity. This not only simplifies the process and makes it automatic carried out, but also increased the quality.
- Diagram 1 shows an embodiment of the invention automated process control.
- a process simulation program A with which the straightening process to be automated can be simulated virtually, created and used.
- the process simulation program A will Machine data B, technological process data C of the intended Straightening process, material data D of the straightened good and the desired Quality S (straightness or flatness, residual stress state over the Guide cross-section, material properties, e.g. B. a desired one Yield point and / or an influence on the pronounced yield point) of the target material.
- the process simulation program A is subject to a variation calculation F, in the parameters, for example the geometric dimensions and / or the yield strength of the target material can be varied.
- the parameters are varied, on the change of which the straightener or the straightening machine E should react automatically.
- the parameter variations are based on the specifics of the respective straightening process and / or the To align straighteners or straightener E.
- Results of Variational calculation F are product and / or process data and those for Automation necessary targets, d. H. the necessary Employment of the standard role (s) to achieve the desired quality. All calculation results of the variation calculation F are in the form of relationship matrices G stored in a database H.
- a process computing model J is provided that on the relationship matrices G and thus on those in the Preparation phase I established relationships between the Influencing factors and the target variables of the straightening process and in Dependency of the recorded production data O from the parent Material flow or the material tracking system (MVS) P die Relationship matrix selection K and the corresponding retrieval.
- the process computing model J realizes on this basis and under Consideration of product and / or process data determined by measurement M the calculation and output of the target values, d. H. the setpoint values L using methods of assessing statistics. For the Basic automation N, these target values correspond to the target values Sw. The current actual values Iw are compared with the target values Sw, whereby the deviations are used to align both values.
- the metrologically determined product and / or process data M are in the database H is stored in form Q. You can in one following preparatory phase for optimization R des Process simulation model and the process simulation program A contribute.
- a correspondingly implemented implementation phase II consists of several Operators.
- an operator for setting or automatic Correction of the setting values are an operator for the basic setting of the Straighteners or straighteners immediately before the start of production as well as an operator for data acquisition.
- a thickness measurement e.g. B. with the help of Laser distance sensors.
- the thickness value is sent to the operator of the Hand over employment.
- a value for the yield strength of the Material that either comes from the parent material flow or Material tracking system P comes or with the help of Yield strength operator is determined.
- the yield point operator uses in addition the information content of a selected from the database H and retrieved relationship matrix G and measurement results of the process variable Directivity.
- the yield point determined by the yield point operator is checked for plausibility.
- the operator of the employment can with the Information on the thickness and yield strength of the leveling material at Use selected and retrieved relationship matrices G die Transfer the setpoint values to basic automation N. That means, that the attitudes derived in this way Straightening roll (s) the respective thickness and the yield strength of the straightening good consider. This allows the quality of the target material to be independent of fluctuations in these two parameters.
- the invention enables others in addition to the directivity Use process parameters for automation and / or on To react to fluctuations in other target material parameters.
- shape curve of the straightening good in a straightener or a Straightener measured and compared with a simulated shape curve become.
- the results of the comparison allow detailed statements to the straightening good or the state of the straightening process.
- ways of organizing litigation which depends on the frequency of the change in the properties of the target are, for example, from batch to batch, from target material to Alignment and / or change over the length of the alignment.
- the solution shown in diagram 2 has the letter in Diagram 1 corresponding units or values, which are therefore not to be explained further.
- the process simulation program A that the metrologically determined product and / or process data M and takes into account the recorded production data O, the target values L directly the basic automation N further.
