Definitions

  • the invention relates to a stretch-bending straightening system according to the preamble of claim 1 and a method for its actuation according to the preamble of claim 10.
  • Stretch-bend-straightening systems such as those in Fig. 3
  • the system shown schematically are systems that are used to minimize internal tensions in ferrous and non-ferrous metallic strips and thereby achieve better flatness.
  • Metallic bands are understood to mean any band-shaped materials.
  • the term “metallic” includes metals per se as well as their alloys. Since the strips show unevenness after the previous rolling process, the straightening process is carried out. These unevenness are caused by fibers of different lengths in the material and are shown by wavy deformations in the strip. This is for explanation in the Figures 4a, 4b as Figures 5a to 5d shown.
  • Has the band-shaped material 10 according to FIG Figure 4a Waves 12 are different fiber lengths according to Figure 4b responsible.
  • the adjacent fibers have a different difference in length ⁇ L.
  • These wavy deformations can appear in the strip-shaped material 10 as central waves 13 according to FIG Figure 5a , as edge waves 14 according to Figure 5b , as one-sided edge waves according to Figure 5c or as a combination of edge waves 14 and center waves 13.
  • the stretch-bend-straightening system shown here generates a pull-up area in which the strip-shaped material 10 is stretched by means of a brake S-block 16 and a pull-S-block 18 that is fed from a coil arranged on a decoiler in the running direction 24 becomes.
  • the designation “S” is used to clarify that the strip is guided around rollers in an S-shape in these areas.
  • the tension that occurs is measured by a measuring device 22.
  • the strip is subjected to 26 alternating bends in the bending and straightening unit. With these two measures, the shorter fibers are aligned with the longer ones and internal stresses are reduced.
  • the strip-shaped material thus straightened is then wound up again on a recoiler 28.
  • an unevenness measuring system (UMS), which can be obtained from Ungerer Technology GmbH, can also be used according to the state of the art Fig. 8 can be used.
  • This unevenness measuring system was specially designed to measure the unevenness of strips with relatively low specific strip tension. It determines the unevenness over the entire bandwidth of the product after the pull S-block 18 and is able to adjust the individual supports of the bending-straightening unit 26 so that an optimal straightening result is achieved.
  • sensitive force sensors are used for the UMS, which are mounted on a fixed axis.
  • a measuring roller 36 is preferably used for this.
  • the controller C calculates the optimal parameters for the straightening process and thus regulates the setting of the supports, i.e. the support rollers 32, via a programmable logic controller PLC by means of a position controller 38.
  • the UMS is as close as possible to the straightening process directly after the pull-S-block 18 in the pull-down area arranged in order to keep the dead distance 42 as small as possible.
  • the dead distance is the distance that the material needs to get from the bending / straightening unit 26 to the measuring roller 36 before an unevenness can be determined on the measuring roller, which then starts a control process in a closed control loop.
  • DE 22 03 911 A1 discloses a method and apparatus for controlling the flatness of a metal strip. Unevenness is detected by distance sensors and the immersion depth of the straightening rollers is then readjusted accordingly. This is done by intervening in a controlled system, but not by selecting a high pressure area or a pull-down area.
  • Fig. 9 The measuring system shown is known, which is used in the high-tension area.
  • a roller of the tension S-block 18 arranged after the bending and straightening unit 26 is replaced by a measuring roller 40.
  • This roller consists of a massive body.
  • the sensors are used on the circumference of the solid roller body and the entire running surface of the measuring roller 40 is covered with a PU coating.
  • the sensors are able to detect the smallest differences in force in the belt.
  • the force values determined are then transmitted to evaluation electronics as evaluation unit 34, processed there accordingly and transmitted to a controller C for calculating optimal parameters for the straightening process in a closed control loop.
  • the advantage consists in a significantly shorter dead section 42 compared to the above-mentioned UMS system.
  • the present invention is based on the object of designing a stretch-bending-straightening system and a method for its actuation in such a way that the quality of the strips processed with it is increased.
  • the stretch-bending-straightening system has a feed means for feeding a strip-shaped material into a pull-up area and a pull-down area, the pull-down area being arranged downstream of the pull-up area in the running direction of the strip-shaped material.
  • a bending and straightening unit is located in the pull-up area.
  • a measuring system for determining first measured values in the pull-up area and a measuring system for determining second measured values in the pull-down area are provided.
  • a controller is provided to determine the deviation of the first measured values from a predetermined or predeterminable target value of the bending alignment result and a controller is provided to determine the deviation of the second measured values from this target value.
  • Manipulated variables are determined by the controller or controllers in order to minimize the deviations within closed control loops.
  • at least two measuring systems are provided, one in a pull-up area and one in a pull-down area, in order to optimize the quality of the material to be processed as required.
  • Selection means can be used to decide whether the first or the second closed control loop is used for optimization. Such a selection can be made according to certain criteria that are either based on empirical values or material parameters, but can also only be newly formed in the course of the process, since in the respective closed control loop in the pull-up area as well as in the pull-down area are measured at the same time, so that based on the parameters determined in this way an optimization can be selected. This allows a high quality tape to be produced in a simple and inexpensive manner.
  • a single controller is preferably provided for the simultaneous determination of the deviation of the first and the second measured values from the setpoint value, so that the selection means alternatively select the first or the second control loop.
  • the controller can without further synchronization between different regulators and controls an optimization can be carried out even in the case of small deviations in such a way that a switch is made from one control loop to the other.
  • An evaluation unit is expediently provided for evaluating the first and / or the second measured values, that is to say more than one evaluation unit can also be provided.
  • the selection means are thereby enabled to select the first or the second closed control loop as a function of the evaluation. Both manual and semi-automatic or automatic selection can be used as selection means, depending on the specifications given to the controller and the evaluation unit.
  • display means are provided for displaying the first and second measured values and / or the selection means are provided for manual selection by an operator. This enables an operator to use the display to see at a glance where the measured values of the two measuring devices are currently moving and thus to decide whether to give preference to the first or the second control loop.
  • the measuring system in the pull-up area is preferably formed by a measuring roller arranged after the bending / straightening unit. It is particularly advantageous if a roller of a tension S-block, which is usually arranged after the bending-straightening unit, is replaced by a measuring roller, on the circumference of which sensors are used and the running surface of which is covered with an elastic coating is. As a result, it can be determined almost immediately after the bending-straightening unit whether a good quality result is obtained in the pull-up area, so that the dead distance between the bending-straightening unit and the measuring system is shortened.
  • the measuring roller is designed as part of the Werner-S-Block, no separate measuring system or no separate storage is required for such a roller; instead, the roller already present in the Werner-S-Block can be replaced by the measuring device, which further reduces the cost of the entire construction.
  • the measuring system for determining the second measured values in the pull-down area is advantageously to be arranged after the pull-S-block, whereby it is arranged as close as possible to this block becomes. Such an arrangement helps to reduce the dead distance and thus the reject for this measuring system as well.
  • the measuring roller used for this has measuring segments arranged next to one another with at least one sensor, preferably with two force sensors, since it is particularly important in the pull-down area to detect the differences over the bandwidth as precisely as possible over the entire area. While some deformations are not perceptible in the pull-up area due to the forces occurring there, these occur more frequently again under lower pulling forces in the pull-down area after elastic recovery and can therefore be clearly recognized there. In addition, a finer resolution is advantageous, which can be achieved by the arrangement of the measuring segments.
  • the strip-shaped material is fed to the pull-up and pull-down area.
  • First and second measured values are determined in the pull-up area as well as in the pull-down area, and a deviation from a target value is determined.
  • a manipulated variable for the bending and straightening unit is calculated for both measuring systems, which can help optimize the result.
  • predefined or predefinable criteria such as a deviation from the nominal value, but also empirical values or material parameters, it is then selected whether to work with the first or second closed control loop to achieve the desired result.
  • the deviation of the first and second measured values is preferably determined simultaneously for both measuring systems by means of a single controller, so that the first or second closed control loop is selected as an alternative. According to the procedure, all information is therefore available at the same time in order to be able to make an informed decision.
  • the first and second measured values are expediently evaluated according to predetermined criteria with a view to achieving a good result, the corresponding control loop then being selected as a function of the evaluation.
  • criteria can initially be certain requirements for the quality of the strip to be processed, but they can also be material characteristics or empirical values that are specified by the operator or can be taken from expert knowledge that is possibly stored in a database.
  • the first and second measured values are advantageously displayed to an operator at the same time, so that the operator can select the optimal control loop for the result to be achieved via selection means 48.
  • This allows the operator to decide at a glance what is the best solution at the moment. Since this can change over the course of time even with a coil, this process can also be automated and monitored so that, if necessary, an indication of a suitable switchover time can be given to the operator.
  • the method is initially operated on the basis of the first measured values from the pull-up area in a first closed control loop until the straightened strip-shaped material reaches the measuring roller in the pull-down area reached, so that it is then possible to switch to the second closed control loop in the pull-down area. Whether or not such a switchover is necessary at this moment can be determined on the basis of the measured values determined. The dead distance can be further reduced by such a configuration.
  • Both the stretch-bending-straightening system and the method can be operated with a program that is set up and / or programmed with a program code in order to achieve the desired results and advantages when the program code is transferred to a computer, a processor or a programmable one Hardware component is running.
  • both measuring systems for the pull-up and pull-down areas are combined for the first time.
  • This system is preferably characterized by the use of a single controller C, but in principle several controllers can also be used.
  • This preferably one controller C is able to evaluate the flatness measured values of the measuring roller 40 in the pull-up area 50 and of the measuring roller 36 in the pull-down area 52. The supports of the straightening machine are adjusted based on these values.
  • the evaluation units 34 of the two measuring units are connected to the controller. This records the flatness values of the two units and uses the measured values of the active measuring unit to calculate the optimal parameters for the straightening process.
  • the system operator preferably determines which of the two measuring units is to be used to regulate the straightening process. He is therefore able to use the more suitable measuring unit depending on the requirements and material and can also use this during a Change process. In order to be able to compare the two units for the respective process, it is possible to visualize the flatness measured values.
  • the measured values of the measuring roller 36 in the pull-down area 52 and the measuring roller 40 in the pull-up area 50 are displayed graphically and / or as numerical values, preferably simultaneously, on a display unit 46.
  • the system according to the invention thus achieves a more precise adaptation of the supports to the unevenness of the strip.
  • Another advantage is that rejects can be permanently reduced in the case of materials for which better straightening results are achieved with the measuring roller 36 in the pull-down area 52.
  • the measuring roller 40 is first activated in the pull-up area 50 and, after the dead section, it is switched to the measuring roller 36 in the pull-down area 52.
  • the measuring roller 40 in the pull-up area 50 is suitable, for example, for high-strength materials. Since the tape is much stronger, the unevenness is not falsified by the high tension. Therefore, in this case, the measuring roller 40 can be used permanently in the pull-up area 50 and thus the advantage of the significantly shorter dead distance can be used.
  • the controller C works with the values of the pull-up measuring roller 40, since its dead distance is significantly smaller.
  • the dead path is understood to be the length of material that is required as a result of the controlled system from an actuating device, the bending / straightening unit 26, to the measuring point before a detected unevenness occurs a controller intervention on the bending-straightening unit 26 leads to an influence on the detected unevenness.
  • the controller C adjusts the bending-straightening unit 26 accordingly with the calculated parameters in order to achieve the optimal straightening result.
  • the controller C switches independently from the pull-up measuring roller 40 to the pull-down measuring roller 36 and regulates the support rollers 32 of the bending-straightening unit with the measured values of the pull-down measuring roller 36, if no other setting is specified by the operator via the input means 49 or by the stretch-bend-straightening system, for example on the basis of previous results already known from the machine.
  • the system operator can intervene manually at any time via input means 49 and switch the controller C as desired. Using the input means 49, he can also enter and specify process data. Furthermore, the system operator can create a database 44 in which, for example, parameters for the process can be saved for materials that have been specified or have already been directed on the system. As a result, the controller C can independently select the optimal measuring roller 36 or measuring roller 40 for repetitive orders.
  • further data can also be stored in the database 44, for example an assignment of certain operating parameters to certain materials or even expert knowledge.
  • Expert knowledge is information on how an experienced operator would operate the stretch-bend-straightener and which parameters he would work with in order to achieve a good result.
  • Further physical properties can also be entered here, such as the operating speed or temperature-dependent properties.
  • both the measuring roller 40 in the pull-up area 50 and the measuring roller 36 in the pull-down area 52 are in engagement and display their measured values, it is possible to interpolate the measured values of the two measuring devices and have the software compare them with one another. This is made possible by, for example, forming an average value for each measuring device and determining this with defined limits at an interval of, for example, 50 control cycles.
  • the controller C can then independently decide which measuring system is more suitable is. This switchover can take place automatically or a recommendation can be made to the system operator.
  • Fig. 2 shows schematically a process sequence.
  • step 100 strip-shaped material 10 is fed to a pull-up area 50 and a pull-down area 52.
  • the material supplied in this way is measured in step 101 by means of a measuring device in the pull-up area, deviations in flatness being determined as first measured values.
  • step 101 the strip-shaped material reaches the pull-down area 52 and there, in step 102, the deviations in flatness are also measured. This leads to the second measured values.
  • step 103 the flatness deviations are compared with a target value for the flatness deviations. If the flatness deviation is less than or equal to the target value, the stretch-bend-straightener is operated with these operating parameters. If the target value is not adhered to, in step 104, preferably on the basis of predetermined criteria, it is selected whether the controlled system in the pull-up area or in the pull-down area will influence the result and thus the flatness deviation. Depending on which route is selected, the manipulated variable for the pull-up area 50 or the pull-down area 52 is calculated either in step 105 or in step 106.
  • the manipulated variable is then applied to the bending and straightening unit 26 in step 107 and the method then jumps back to steps 101 and 102 in order to measure the deviations in flatness in the pull-up area 50 and in the pull-down area 52, respectively.
  • the process then starts from the beginning.
