  • the straightening roller 2 , 3 is supported in operation, to which end a number of support rolls 4 are disposed along the axial extent of said straightening roller 2 , 3 .
  • the support rolls 4 are held by a support roll mounting 11 .
  • a bending system 8 having a plurality of bending cylinders acts on the support roll mounting 11 . Said bending cylinders exert a defined bending moment on the support roll mounting 11 so that the support roll mounting 11 bends jointly with the support rolls 4 . This flexing is illustrated in a highly exaggerated manner in FIG. 2 .
  • a metallic flat material 6 (steel strip) is straightened by means of the straightening roller 2 , 3 , to which end the straightening roller 2 , 3 is driven at a defined torque and at a defined rotating speed by a drive 10 .
  • the flat material 6 is conveyed herein in the conveying direction F.
  • the strength of the straightening force which is exerted by the straightening roller 2 , 3 on the flat material 6 depends substantially on the corresponding actuating motion of the straightening roller 2 , 3 , this in turn being accomplished by the bending system 8 .
  • the straightening roller 2 , 3 has a local region of wear 9 which would lead to a faulty straightening process.
  • the diameter in the center of the straightening roller 2 , 3 has dropped from an original value D to a reduced value d.
  • FIGS. 1 and 2 in combination, illustrated in a highly exaggerated manner in FIG. 2 , it is derived that on account of a corresponding actuation of the bending system 8 , such a bending force is exerted on the bending roller 2 , 3 that it bears in the region of contact with the flat material 6 on the latter in a largely cylindrical manner.
  • a machine controller 7 which comprises a correction value determination 13 is provided (cf. FIG. 2 ).
  • a memory 12 for wear values is connected to the machine controller 7 .

  • FIG. 1 shows an upper straightening roller 2 having the diameter D, said upper straightening roller 2 being in contact with the material 6 to be straightened.
  • the straightening roller 2 is supported by a number of support rolls 4 (in other construction modes the straightening roller is supported by only a single support roll, also referred to as a support roller; the present invention comprises both).
  • a bending system 8 that is composed of a plurality of bending cylinders acts by way of the support rolls 4 on the barrel of the straightening roller 2 and thus can set the flexing of the straightening roller 2 across the length of the barrel.
  • each straightening roller 2 is capable of being set in its entirety in terms of the plunging depth thereof by an actuating system not illustrated in FIG. 1 (said actuating system is identified by the reference sign 5 in FIG. 3 ).
  • FIG. 2 shows the operating mode of the proposed solution in the same configuration as in FIG. 1 :

  • Each straightening roller 2 , 3 has a dedicated drive 10 (cf. FIG. 1 ) by way of which the rotating speed and the torque are controlled.
  • Each straightening roller 2 , 3 has a dedicated actuation in order for the plunging depth, i.e. the complete vertical setting, to be set independently of the bending across the roller barrel. For reasons of simplification, an illustration of the support rolls and the bending cylinders has been dispensed with in figure 3 .
  • the schematic illustration shows that the machine controller 7 positions the actuation in the case of worn-out straightening rollers in such a manner that a plunging depth required for the straightening procedure is achieved even when there is wear. This is achieved by increasing the actuation stroke by the wear value, in this case the difference in terms of the diameter.
  • the drive parameters in terms of torque and/or rotating speed for the worn-out straightening rollers are corrected by the machine controller 7 such that the smaller straightening roller diameter is compensated.
  • the straightening task can be carried out in an optimal manner.

  • the proposed concept first serves for setting the system prior to carrying out a straightening procedure.
  • the state of wear of the tools first has to be determined by way of suitable methods. Subsequently, the required correction value or an equalization parameter is calculated by way of, said correction value or equalization parameter resulting in a new actuation parameter/setting value that is modified in relation to the tool that is not worn out.
  • the machine controller 7 transfers the corrected actuation parameters to the individual tools such that the operating parameters of said individual tools, the so-called tool functions, are set.
  • the computer unit for determining correction values and the machine controller can be separate units (cf. FIG. 3 ), but can also be integrated in a common unit (cf. FIG. 2 ).
  • the tools that are not worn out receive a correction value of “zero”, that is to say that the originally provided setting is not corrected.
  • the fundamental procedure of setting the roll straightening machine is not discussed in more detail here since this is well known in the prior art.
  • the central objective here is rather to solve the problem of wear and the integration of said solution in the setting of the system.
  • tools that are worn out and tools that are not worn out can be used simultaneously in a straightening machine without suffering any losses in terms of the quality of the straightening procedure.
  • the identification of wear can be performed by a manual input by the operator personnel after manual measuring.
  • a potential automated method step of determining wear lies in the determining of the wear by way of a nominal/actual comparison of process nominal values with measured process actual values and in drawing conclusions pertaining to the wear.
  • deviating values pertaining to straightening force, torque, resilience, etc. can be resorted to.
  • the measurement can be carried out in the form of travel measurement systems, force measurement systems, and/or pressure measurement systems having a corresponding sensor mechanism installed in the straightening machine.
  • a further potential automated method step for determining wear can be performed in the form of an empirical determination of wear values. Moreover, the determining of wear can also be performed by way of a system calibration in that the results of a system calibration carried out are compared with the results of one or a plurality of previous system calibrations.
  • the determination/calculation of the correction values is performed in a separate computer unit or directly by the machine controller 7 . This depends on the detailed design embodiment of the system automation and system management.
  • the calculation of the correction values is preferably performed by a technological straightening machine model which calculates the setting values (also the actuation) and the wear-related correction values for the setting.
  • a long-term and/or short-term adaptation of the straightening machine model while considering the wear parameters represents a further improvement. This can be performed independently of the straightening machine model, in the form of a separate wear model, or the straightening machine model has an implemented wear model.
  • the machine controller 7 performs the setting of the system, thus the targeted transmission of the operating positions and operating values to the respective tools.
  • the machine controller 7 transfers the corresponding actuation parameters/setting values to the tool functions.
  • the plunging depth is thus set by way of the actuation of the straightening roller 2 , 3 by way of a corrected actuation parameter, as is a corrected actuation parameter for the rotating speed and/or the torque of the roller drive.
  • a preferred correction of a tool function is assigned to the forms of wear. Wear across the entire straightening roller barrel is preferably corrected by the actuation of the straightening roller and the rotating speed of the latter, local wear of straightening rollers is corrected by the bending cylinders and the straightening roller rotating speed, wear of support rolls is corrected by the actuation and/or the bending cylinders. Further combinations are possible.
  • the roll straightening machine has means for identifying wear, for example in the form of the sensor mechanism already mentioned above.
  • Said roll straightening machine 1 additionally has the means for compensating the wear.
  • Said means for compensation are preferably composed of a combination of individual roller actuations, thus the possibility for each straightening roll to be individually set in terms of the plunging depth thereof, in conjunction with an individual roller drive (thus an individual drivetrain having a rotating speed and torque that are capable of being set).
  • a bending system by way of which the contour of the straightening roller can be influenced is provided for each straightening roll, so as to correct local wear in a targeted manner (to this end cf. reference sign 9 in FIG. 1 ).
  • a further feature for improving the straightening result while considering wear parameters is the closed-loop load equalization control of the individual adjacent straightening roller drives. Undesirable distortions in terms of torque or rotating speed, respectively, are thus equalized.
