Definitions

  • the subject of the invention is a method for controlling the trajectory of the product in a nested roller planing machine and the planing installation for implementing the method.
  • a multi-roll planer For planing flat products and, in particular, laminated metal strips, a multi-roll planer is often used comprising two planing equipments each carrying a series of rollers with parallel axes and placed, respectively, above and below the strip, the rollers being offset longitudinally and vertically so as to interlock by determining a corrugated path of the strip which is thus subjected to tensile-bending effects in alternate directions.
  • the operation of such a machine has been the subject of advanced theoretical approaches. These theories of planing are based on the calculation of the maximum curvatures of the sheet in the planer, these curvatures cause a plasticization of the material in the thickness of the product which conditions stress relieving in the width and the thickness.
  • Any planer can be broken down into two zones whose functions are very different but complementary and interactive.
  • the entry zone which includes the first three or four rollers, is a large plasticizing zone in which visual flatness defects such as long or long center edges, "quarter-band" defects and any distribution are eliminated. transverse heterogeneity of longitudinal stresses.
  • the exit zone which includes the last three or four rollers, has the function of reducing the gradients of the normal and transverse stresses in the thickness to ensure the sheet metal hanger and tile residual almost zero.
  • a leveling installation therefore generally comprises a fixed support cage, two parallel roller leveling equipments placed respectively above and below the strip and whose rollers are nested so as to determine a path corrugated the band and means for adjusting and maintaining the spacing of said crews by pressing the fixed cage for adjusting the nesting of the rollers, each leveling unit having a row of parallel active rollers supported on a frame of support by means of at least one row of support rollers and rotatably mounted at their ends, each on two bearings defining an axis of rotation perpendicular to the direction of travel, said bearings being carried, respectively, by two side parts secured to the support frame.
  • the lower leveling crew is fixed in position, the upper crew being able to move vertically for nesting adjustment.
  • the upper crew being able to move vertically for nesting adjustment.
  • it is generally used four mechanical or hydraulic actuators mounted at the corners of the frame and to adjust the general level of the adjustable crew relative to the lower fixed crew and, therefore, the nesting rollers.
  • the input and output actuators can be set differently, which allows to determine a tilt generally necessary to achieve the two planar effects established by the theory and discussed above.
  • the actuators can also be adjusted differently from one side to the other by introducing lateral tilting so as to correctly distribute the planing effect over the width of the product to be hovered.
  • planers a structure as rigid as possible so as to control the effects of planing.
  • the deformation under stress of the different parts of the machine (also called ceding) distorts the accuracy of the control of the position of the leveling rollers, therefore the exact value of the curvature obtained on each roll.
  • ceding distorts the accuracy of the control of the position of the leveling rollers, therefore the exact value of the curvature obtained on each roll.
  • the overall capping of the machine modifies the desired level of plasticization, so risk in the entry zone of not completely eliminating flatness defects, it also modifies the decay rate of the plasticization, therefore the transition with the exit zone and may not eliminate residual stresses as expected.
  • hydraulic level planers were made for moving the moving planing equipment, and also for the individual control of each leveling roller, and a capping model based on effort and a theoretical calculation of the deformations of the machine under effort, to compensate for these deformations, as in the applicant's patent FR 2,732,913 .
  • the capping module of a leveling machine is of the order of 100 t / mm per column, while the leveling force for a sheet of 3 meters of width can be from 1000 tonnes to 2500 tonnes. which leads to a cedar (without compensation) of 2.5 mm to 5 mm.
  • the precision required is not very high in the entrance area of the machine and could accommodate a simple compensation cedar, there is however the risk of having refusal of commitment of the product in a machine set too tight as a precaution.
  • the necessary precision on the curvatures for the elimination of the residual stresses in the exit zone requires a precision of the control of the position of the rollers by a few tenths of a millimeter.
  • the control of the transition zone finally implies having precise control on practically all the rollers, all the more so as for certain applications the steps of the rollers rigidly held in position will be varied so as to increase the capacity of the planer as it says in the patent FR 2,732,913 . This will have the effect of moving the entry zone and the exit zone and will therefore also contribute to a search for greater accuracy in controlling the position of all the rollers of the planer.
  • the invention therefore aims to increase the accuracy of control of these machines and a machine equipped with a new control device and to solve all of these problems without causing complication or excessive cost of the devices used.
  • the compensation of the cages is replaced by a real-time model of presetting of the position of the planing rollers associated with a direct measurement of the spacing of the active rollers.
  • a theoretical presetting model is installed which gives at least one reference value for the pre-adjustment of the nestings and one directly measures at least one value of the spacing of the planing rollers, which is compared to the reference values and acts on the adjusting members of the position of the leveling rollers to maintain the measured values equal to the values of the reference so as to maintain the trajectory of the product to be hovered inside the machine in accordance with the ripple provided by the model to achieve planing.
  • a measurement is made of the value of the spacing of each of the leveling rollers which is compared with each reference value given by the model and acts on the individual adjustment members of the position of each of the leveling rollers to maintain the measured value equal to the value of the reference so as to achieve the corrugation and the decrease in the rate of plasticization provided by the model for performing leveling.
  • the position control requires to ensure that at uniform positions of planing rollers, given by position sensors, correspond identical leveling forces. It is necessary first to perform a kind of calibration so as not to depend on the mounting mode of the sensors in the machine and the position of their reference 'zero'.

  • equilination is carried out on a moving sheet by differentially modifying the position of the active rollers by a lateral tilting from one side to the other and that one proceeds to the equalizing the averages of the forces recorded by the measuring devices on each side during said scrolling.
  • a device for directly measuring the value of the spacing of the leveling rollers in at least one point so as to know the exact value of the nesting by a direct measurement preferably comprises an electronic device for controlling the measured spacing of the planing rollers to the theoretical value given by the model by acting on the adjustment devices of the nesting.
  • the adjustment devices of the nesting are hydraulically controlled.
  • the installation is provided with a device allowing the direct measurement of the value of the spacing of the leveling rollers in at least two points, one located in the zone d entry of the machine and the other located in the exit zone.

  • These devices are preferably hydraulically controlled.
  • independent devices allow the direct measurement of the spacing value of each pair of active planing rolls separately.
  • the parallel roll leveling installation comprises means for individually adjusting the position of each leveling roller and an electronic device enabling the measured distance of each of the leveling rollers to be controlled at the theoretical value given by the model for the leveling roller. spacing of each of these rollers by acting independently on their nest adjustment device.
  • the leveling installation advantageously comprises a device for adjusting the interlocking of each hydraulically controlled roller,
