Definitions
- the invention relates to a method for the automated guidance of a straightening process for a straightening good, such as sheets, strips, profiles, tubes and in particular for a wire or multi-wire shaped straightening good in a straightening apparatus or in a straightening machine with at least one straightening roller adjustable by an actuator.
- a straightening good such as sheets, strips, profiles, tubes and in particular for a wire or multi-wire shaped straightening good in a straightening apparatus or in a straightening machine with at least one straightening roller adjustable by an actuator.
- Non-rotating roller straighteners or straighteners are used to remove curvatures from straightening goods.
- the straightening rollers which are mutually offset in two rows, relative to one another, in at least one straightening plane, the straightening material experiences changing bends during its passage. These alternate bends should be of such a number and size that the inlet curvatures of the leveling material are eliminated over the entire length of the leveling material.
- a non-rotating straightening device for bending machines with an integrated measuring device is known from DE 195 03 850 C1.
- At least one material bending measuring device is arranged in the direction of flow of the material behind at least one straightening unit, in which at least one measuring section is provided for a length of material that is predetermined in length, with at least one mechanical and / or electronic measuring the extent of the bending and the sense of bending along the measuring section and / or an optical scanning device is arranged, with the scanning device generating signals representing the measured bending of the material section, with which an actuator is adjusted accordingly.
- the measuring device of the known straightening apparatus works on the principle of determining the curvature according to the three-point method, which is only used for cut-to-length straightening goods or for stopped straightening goods, i.e. H. if the target is free of external forces and moments, neglecting gravity, gives correct results. If the curvature of the straightening material to be discharged is 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 is interrupted by the necessary stopping of the straightening goods. Stopping and restarting influences the result of the curvature measurements and causes changes that affect the quality of the straightening process. This means that the setting can only be checked by stopping the straightening device again, ie continuous monitoring and regulation while the straightening material is running or during straightening is not possible.
- the object of the invention is to provide a method which practically enables instantaneous, automatic adjustment of the setting of at least one straightening roller of a straightening apparatus or a straightening machine to continuously measured data of the respective straightening good without stopping the straightening process.
- the invention is summarized, including advantageous embodiments, the principle of modeling the straightening process to be automated using mathematical-physical laws in a preparatory phase, creating a simulation program and using the simulation program to perform a variation calculation with variation of the product data, in particular the material properties and / or the dimensions of the target.
- This phase can be regarded as "offline”.
- the settings required to achieve the desired product quality are made very quickly, including the results of the variation calculation "online" of the straightener or straightener.
- the change in the setting is objective and determined.
- the measured product and / or process data are also used to check the model created and the simulation program and, if necessary, to change it.
- the sense of proportion of the objectivity occurs when the straightener or the straightener is operated. This not only simplifies the process and carries it out automatically, it also increases the quality.
- Diagram 1 shows an embodiment of the automated process control according to the invention.
- a process simulation program A with which the straightening process to be automated can be virtually simulated, is created and used.
- machine data B technological process data C of the intended straightening process
- material data D of the straightening good and the desired quality S (straightness or flatness, residual stress state over the straightening material cross section, material properties, e.g. a desired yield point and / or an influence on the pronounced yield point) of the straightened product.
- the process simulation program A is subject to a variation calculation F, in which parameters, for example the geometric dimensions and / or the yield strength of the material to be straightened, are varied.
- the parameters are preferably varied, to the change of which the straightening apparatus or straightening machine E should react automatically.
- the parameter variations are to be matched to the specifics of the respective straightening process and / or the straightening apparatus or the straightening machine E.
- Results of the variation calculation F are product and / or process data and those for Automation necessary target values, ie the necessary employment (s) of the standard role (s) to achieve the desired quality. All calculation results of the variation calculation F are stored in a database H in the form of relationship matrices G.
- a process calculation model J which uses the relationship matrices G and thus the relationships between the influencing variables and the target variables of the straightening process created in preparation phase I and depending on the recorded production data O from the higher-level material flow or the material tracking system ( MVS) P performs the relationship matrix selection K and the corresponding call.
- the process calculation model J realizes the calculation and output of the target values, taking into account product and / or process data M determined by measurement technology.
- H the setpoint L with the help of methods of assessing statistics.
- these target values correspond to the target values Sw.
- the current actual values Iw are compared with the target values Sw, the deviations being used to match the two values.
- the product and / or process data M determined by measurement technology are stored in the form H in the database H. You can contribute to the optimization R of the process simulation model and the process simulation program A in a subsequent preparation phase.
- a corresponding implementation phase II consists of several operators.
- an operator for setting or automatically correcting the setting values there is also an operator for basic setting of the Straighteners or the straightening machine immediately before the start of production as well as an operator for measuring value implementation.
- a thickness measurement is carried out, e.g. B. with the help of laser distance sensors.
- the thickness value is transferred to the operator of the job.
- a value for the yield point of the leveling material is received, which either comes from the higher-level material flow or material tracking system P or is determined with the aid of the yield point operator.
- the yield point operator uses the information content of a relationship matrix G selected and retrieved from the database H 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 job can transfer the job setpoints to the basic automation N with the information on the thickness and yield strength of the target material using selected and retrieved relationship matrices G.
- the invention also makes it possible to use other process parameters for automation and / or to react to fluctuations in other straightening material parameters.
- the shape curve of the leveling material can be measured in a leveling device or a leveling machine and compared with a simulated shape curve. The results of the comparison make it possible to make detailed statements about the straightening good or the state of the straightening process.
- the solution shown in diagram 2 has units or values corresponding to the letters in diagram 1, which are therefore not explained further.
- the process simulation program A which takes into account the metrologically determined product and / or process data M and the acquired production data O, directly passes on the target values L to the basic automation N.
