Definitions

  • the invention relates to a device and a method for winding and / or unwinding a tape, preferably for winding a metal tape into a bundle in metal processing.
  • a windable metal strip - for example after exiting a roll stand of a rolling train - in a coil box to form a bundle, also referred to as a coil.
  • the coil box usually has several bending rollers that bend the tape and thus bring it into a position suitable for winding, and winding rollers that usually wind the tape without a mandrel, ie with the eye open.
  • the coil box can also have means for transporting the strip, as well as for repositioning and unwinding the bundle.
  • Such a coil box is, for example, in the DE 198 03 091 A1 described.
  • rollers involved in the transport, bending and winding of the tape are exposed to different loads during the process, which means that they wear out at different speeds and in different ways.
  • the times of engagement and angles of attack of the tape relative to the rollers change over time. This problem occurs more intensely when several rollers are driven by a common drive train.
  • the WO 2009/097957 A1 describes a method in which the peripheral speed of the bending rollers is adjusted to the surface speed of the metal strip at the contact line. This can reduce the slip between the metal band and the bending rollers, but are the bending rollers continue to be exposed to different loads - for example different times of engagement, angles of attack, compressive forces, etc. - which can result in different wear behavior.
  • the DE 10 2006 023 602 A1 which forms the basis for the preamble of the independent claims, describes a device for bending a coil eye, the bending rollers of which have a non-cylindrical cut shape.
  • One object of the invention is to provide a device and a method for winding and / or unwinding a strip, preferably for winding a metal strip into a bundle in metal processing, which reduces the wear behavior of rollers, in particular transport, guide, bending and take-up rolls.
  • the device is used for winding and / or unwinding a tape.
  • the tape is preferably a metal tape.
  • the strip can be a metal strip which runs out of a roll stand and which is wound up by the device to form a bundle.
  • the device has several roles.
  • the rollers serve, for example, for transporting, guiding, bending, winding and / or unwinding the tape and are at least temporarily in contact with it.
  • At least one role, preferably several or all roles, has one or more changeable manipulated variables that can be set by an adjusting device.
  • a variable physical, preferably mechanical, property of the role is referred to as “manipulated variable”.
  • the speed of rotation of the roller can be a manipulated variable, as can the torque, the position and / or alignment of the roller, etc.
  • the manipulated variable can also indirectly describe the state of the roller, for example by relating to a variable for controlling a drive of the roller. In this sense, for example, the speed of rotation of the roller is also considered a possible manipulated variable, as is the motor torque of the drive or the excitation current for actuating the drive.
  • the manipulated variable can identify the position of the roller, the position of the piston in the cylinder or the pressures for actuating the hydraulic cylinder. It is important that one or more manipulated variables can be set by a control unit, which is referred to here as an actuating device.
  • the device also has a wear determination device which is set up to determine a state of wear of at least one of the rollers.
  • the state of wear comprises at least one physical property of one or more rollers that changes in the course of the operation of the device due to wear. For example, contact of a roller with the tape can cause a profile change or a change in the diameter of the roller over time.
  • the device preferably has a plurality of driven rollers, each of which has at least one manipulated variable, which can be set by the adjusting device, and is driven by its own drive train.
  • the drive train preferably comprises a drive gear so that the driven rollers are decoupled at least with regard to the gear, whereby the different wear behavior can be taken into account.
  • the individual Drive trains also have their own motors, such as electric motors, in order to further optimize wear behavior.
  • the diameter of one or more rollers can be measured continuously or at certain intervals during operation, the change of which over time is used as a determining parameter of the state of wear.
  • the profiles of rollers can be measured or theoretically determined and included in the state of wear.
  • manipulated variables can be taken into account as well as the belt thickness, belt width, belt temperature, bending force, the bundle weight, the bundle size, etc. The state of wear determined on an experimental and / or theoretical basis is therefore a measure of the wear of one or more rollers.
  • the adjusting device is set up in such a way that it changes one or more manipulated variables, taking into account the determined state of wear.
  • the control of one or more rollers such as setting rotational speeds and / or the timing of the opening of the bending rollers and / or the lowering of winding rollers, etc., takes into account the determined wear condition.
  • one or more manipulated variables can be set during regular operation of the device, i.e. while a tape is being wound.
  • the wear behavior can be optimized.
  • the wear and tear of different rollers can be made more uniform, thereby increasing their operating time and reducing maintenance times and times in which the device is idle due to wear.
  • the wear optimization insofar as it includes bending rollers and / or winding rollers, also contributes to an improvement in the collar eye diameter, the ovality of the collar and the collar opening sequence.
  • the production security is increased by a reduction the cobbler rate improved.
  • the associated improvement in the wear forecast also improves the downtime and spare parts planning.
  • the optimization of the wear behavior can be carried out by readjusting the setting values of the roller drives on the basis of the measured and / or otherwise determined wear on different rollers, e.g. based on the different intervention times, bandwidths and the loads that occur, as well as the input roller shape, i.e. the original roll shape the change due to wear, and the roll base material.
  • Typical wear behavior is known as the "coffin profile”. This means the tendency that rollers wear faster in the middle than at the edges due to a higher load in the middle than at the edges (viewed in the axial direction), which results in a concave wear profile. Such wear behavior can be counteracted by applying layers of different hardness along the axial extent of the roller.
  • a further measure which relates to a preferred embodiment, consists in achieving an equalization of the load distribution through the fluctuation of the strip width by shifting the roller laterally.
  • a measure for the lateral position or displacement of the roller represents a manipulated variable in the sense defined above, which can be set via the actuating device, taking into account the state of wear.
  • the method according to the invention is used for winding and / or unwinding a strip, preferably for winding a metal strip in metal processing.
  • the technical effects, preferred exemplary embodiments and contributions to the state of the art that have been described in relation to the device apply in an analogous manner to the method.
  • the device and the method are particularly suitable for optimizing the wear of bending rolls and / or winding rolls in coil boxes.
  • the invention can also be implemented in other areas, for example to optimize the wear and tear of transport rollers, guide rollers, unwinding rollers, etc.
  • the Figures 1 to 6 show in a schematic way the arrangement of bending and winding rollers of a coil box in the course of winding a metal strip.
  • the Figure 1 shows an arrangement of bending and winding rollers in a coil box for winding a metal strip.
  • the coil box has a group of bending rollers with two upper bending rollers 10a, 10b and a lower bending roller 11.
  • the upper bending roller 10b and the lower bending roller 11 define a bending gap B through which the tape 1 to be wound (cf. Figures 2 to 6 ) is passed through.
  • the adjustment of the upper bending rollers 10a, 10b relative to the lower bending roller 11 can be changed by means of an adjusting cylinder 12.
  • the lower bending roller 11 is designed to be stationary in the present exemplary embodiment, but its position can also be provided to be adjustable.
  • the coil box also has two take-up rollers 20a, 20b, which hold the bundle 2 (cf. Figures 4 to 6 ) carry and store rotatably.
  • the adjustment of the take-up rolls 20a, 20b can be changed by means of an adjustment cylinder 22.
  • the adjusting cylinders 12, 22 are each designed as hydraulic cylinders, but there is no restriction in this regard.
  • the rollers can be adjusted in various ways, for example by an electric motor or magnetically. The roles can also be adjusted in groups or individually.
  • the coil box according to the present example has, for example, a forming roller 30 and three contact elements 31a, 31b, 31c which contribute to a defined winding of the strip 1.
  • the adjusting cylinders 12, 22 are controlled by an adjusting device 40.
  • the actuating device 40 has a wear determining device 50, which is described in more detail below, or communicates with such a device.
  • the Figure 2 shows a state of the coil box at the start of the winding process.
  • the band 1, which passes through the bending gap B, is bent during the transport by the bending rollers 10a, 10b, 11 in such a way that it comes into contact with the contact element 31a.
  • the positions and speeds of the bending and winding rollers 10a, 10b, 11, 20a, 20b are controlled by the actuating device 40, with the rollers with their leads and lags in relation to the belt speed are brought to a certain speed and held.
  • the Figure 3 shows a state in which the tape 1 pre-bent by the bending rollers 10a, 10b, 11 has been transported further in the direction of the take-up rollers 20a, 20b.
  • the tape 1 begins to be wound into a bundle 2 without a mandrel and in contact with the take-up roll 20a, as compared with FIG Figure 4 shows.
  • the adjusting device 40 causes the upper bending rollers 10a, 10b to open, ie the adjusting cylinder 12 moves one or both of the upper bending rollers 10a, 10b away from the stationary bending roller 11, thereby increasing the bending gap B.
  • the direction of the opening of the upper bending rollers 10a, 10b is in the Figure 4 shown by an arrow.
  • the adjusting device 40 also causes the winding rollers 20a, 20b to lower the upper bending rollers 10a, 10b in order to create space for the growing bundle 2. This is also indicated by an arrow from the Figure 5 emerged.
  • the contact condition of the band 1 changes relative to the bending rollers 10a, 10b, 11.
  • the contact of the band 1 changes from contact with all three bending rollers 10a, 10b, 11 to a contact with only two bending rollers 10b, 11, as in FIG Figure 6 shown.
  • the change in the contact state is not only a function of time, ie the process stage, but also depends on other parameters, such as the material thickness of the strip 1, the strip temperature and the strip strength.
  • the coil box has the wear determination device 50. This is set up to determine a state of wear of one or more of the rollers 10a, 10b, 11, 20a, 20b.
  • the state of wear includes at least one physical property of the roll (s) in question, which changes in the course of the operation of the coil box due to wear. For example, a profile change or a change in the diameter of one or more of the bending rollers 10a, 10b, 11 can be included in the state of wear.
  • the state of wear can be determined in various ways. In particular, the state of wear can take place on the basis of a theoretical wear model and / or taking sensor data into account.
  • sensors can be assigned to the bending rollers 10a, 10b, 11, which measure one or more parameters suitable for determining the state of wear, such as the roller diameter, the roller profile, the rotational speed, etc.
  • the sensors communicate with the wear determination device 50, which in turn determines a wear condition from the sensor data and possibly taking into account a theoretical model.
  • the adjusting device 40 is now set up in such a way that it changes the manipulated variables taking into account the determined wear state.
  • the speeds of the bending rollers 10a, 10b, 11 and / or the chronological progression of the opening of the upper bending rollers 10a, 10b can be a function of the state of wear, for example the measured roller diameter.
  • the wear behavior of the rollers can be optimized.
  • the wear and tear on different rollers can be made more uniform, thereby increasing their operating time and reducing maintenance times and times in which the coil box is idle due to wear.
  • the wear optimization also contributes to an improvement in the collar eye diameter, the ovality of collar 2 and the collar opening sequence. Production reliability is improved by reducing the cobbler rate.
  • a more precise wear forecast is possible, which contributes to an improvement in the planning of downtimes and spare parts.
  • the wear determining device (50) is preferably set up to determine the state of wear taking into account measured values measured by one or more sensors, the measured values preferably comprising one or more variables from the following selection: rotational speed of one or more of the rollers (10a, 10b , 11, 20a, 20b); Torque of one or more of the rollers; Change in rotational speed of one or more of the rollers; Change in torque of one or more of the rollers; Profile of one or more of the roles; Profile change of one or more of the roles; Diameter of one or more of the rollers; Change in diameter of one or more of the rollers; Position and / or orientation of one or more of the rollers; Tape thickness; Bandwidth; Belt temperature; Bending force; Bundle weight; Fret size.
