Definitions
- the invention relates to a method for operating a coil box in a metallurgical plant, with continuous real-time collision monitoring.
- the invention also relates to a coil box of a metallurgical plant with continuous real-time collision monitoring.
- a coil box is used for winding and unwinding metal strips in metallurgical plants, for example in a rolling mill of the metallurgical plant.
- the wound metallic strip is referred to as a coil.
- the strips wound up or unwound in the coil box usually have a width of between 500 mm and 2500 mm.
- the coil box includes moving and fixed parts for winding and unwinding and actuators for moving the moving parts of the coil box.
- the actuators are designed as hydraulic cylinders, for example, which are controlled by automation of the coil box.
- the coil ie the metal strip
- the movement possibilities of the roller table of the coil box result in movement trajectories of a coil both in the x and in the y direction.
- the diameter of the coil changes continuously during winding and unwinding.
- the coil box is empty or the diameter of the coil in the coil box remains constant.
- Another essential operating state of the coil box is the maintenance of the coil box, whereby people can be in the sphere of influence of the coil box during maintenance.
- special care must be taken to ensure that the person is not injured by the moving parts of the coil box, also in connection with the fixed parts of the coil box. For example, an area large enough for a person to safely stand upright could be blocked for the moving parts of the coil box to move.
- Another example concerns the movement of certain roller table rollers of the coil box.
- a reel When a reel reaches or exceeds a certain position, the movement of another reel, regardless of whether it is in that constellation, is actually closed a collision occurs or not.
- no movement at all is allowed for safety reasons.
- the invention is based on the object of avoiding unnecessary collisions during the operation of a coil box while restricting movement to a minimum.
- the object is achieved according to the invention by a method for operating a coil box in a metallurgical plant, with continuous real-time collision monitoring, the coil box comprising moving and fixed parts and actuators for moving the moving parts of the coil box, comprising the steps:
- the dimensions of the moving parts and fixed parts of the coil box are recorded.
- the information recorded is essentially geometric data of the moving parts and fixed parts of the coil box.
- This step also includes a coil that may be in the coil box as a fixed part or a coil that is being wound up or unwound as a moving part of the coil box, with the dimensions of the coil changing continuously during a winding process, in particular the diameter of the coil.
- the possible movements of the actuators of the coil box which have an effect on the moving parts of the coil box, are recorded.
- This information is essentially kinematic information.
- a digital model of the coil box is created on the basis of the recorded geometric dimensions of the moving and fixed parts of the coil box and the recorded possible movements of the actuators of the coil box.
- This digital model describes the behavior of the real coil box in operation, taking into account the recorded geometry data and kinematic information.
- the movements of the moving parts of the coil box are monitored based on the created digital model to detect collisions between moving and/or fixed parts of the coil box.
- the method according to the invention thus continuously checks whether the movements of the moving parts of the coil box lead to collisions or not.
- the method according to the invention can adjust the movements of the moving parts of the coil box by means of the actuators.
- Movements and/or collisions between moving and/or fixed parts within the meaning of the invention includes both movements and/or collisions between the moving parts and movements and/or collisions between moving parts and fixed parts.
- the method according to the invention is carried out in real time and continuously monitors the operation of the coil box.
- the created digital model can automatically detect collisions in real time without, as in the prior art, having to be detected in advance and programmed into the automation of the coil box. It is therefore not necessary to check possible movements of the moving parts of the coil box in advance for possible collisions.
- a further advantage of the method according to the invention is that the digital model can carry out the collision monitoring separately for each actuator or the moving parts of the coil box connected thereto. According to the invention, only those movements of the moving parts of the coil box that cause a collision can be adjusted, while other parallel movements of other moving parts of the coil box can be carried out unchanged.
- the aforementioned geometric data and/or kinematic information only has to be determined once for a coil box, since the geometry and kinematics of a coil box do not change. Specifics of the metallurgical plant in which the coil box is used can be made available to the digital model during initialization.
- the created digital model determines the movements of the moving parts of the coil box based on the movements of the actuators of the coil box.
- the actuators are connected to the moving parts of the coil box, with each actuator having one or connected to multiple moving parts. Furthermore, the actuators can be connected to fixed parts of the coil box.
- the moving parts are moved by appropriate actuators through the automation of the coil box by means of appropriate control signals to the actuators.
- the digital model created monitors these movements for any collisions.
- the movements of the moving parts of the coil box are monitored during operation to detect collisions between moving and/or fixed parts of the coil box by a vectorial distance calculation based on the digital model created.
- the method includes detecting that the distances between movable and/or fixed parts of the coil box fall below specified distances.
- the method also includes the generation of a message, an alarm, a setting action or the like when it is detected that the distances between movable and/or fixed parts of the coil box are below specified values. If the distance falls below the specified distance, the method initiates a predetermined action, such as the output of warnings and/or alarms, carrying out adjustment actions, stopping adjustment actions, or the like.
- a predetermined action such as the output of warnings and/or alarms, carrying out adjustment actions, stopping adjustment actions, or the like.
- alarms/warnings are generated if the distance falls below a definable level. They can be used, for example, to issue an approach warning in order to reduce the movement speed of the actuators involved. If another, freely definable distance value is not reached, the movements of the actuators involved are stopped. It is also possible to output the exact distance continuously at the processing speed of the coil box automation and to further process it individually. So different warning and safety thresholds can be evaluated for different operating states.
- the method includes the transmission of adjustment actions from an automation of the coil box to the digital model, in particular actual positions and target positions of the actuators of the coil box.
- the digital model can monitor the movements of the moving parts of the coil box for collisions with other moving and/or fixed parts of the coil box. If the target positions of the actuators, i.e. the end positions of the actuators after the actuating action has been carried out, are also transmitted to the digital model, the digital model can check these target positions in advance for collisions between moving and/or fixed parts the coil box is coming. The digital model can thus make a prediction of possible collisions between moving and/or fixed parts of the coil box for the time horizon of the transmitted adjustment actions.
- the method according to the invention comprises adjusting the target position by the digital model to avoid collisions between moving and/or fixed parts of the coil box and transmitting the adjusted target position to the automation of the coil box. If a collision is detected between moving and/or fixed parts of the coil box as part of the prediction for the transmitted adjustment actions, the digital model adjusts the problematic target positions in order to avoid collisions and communicates the optimized target positions to the automation, thereby this can take into account the adjusted target positions accordingly. The digital model therefore determines those target positions of the actuators that are just not causing a collision or that are below the specified relevant distances.
- the method includes determining directions of movement of the moving parts of the coil box and stopping the movements of the moving parts at least in one direction of movement.
- An actuator such as a hydraulic actuator can normally move in two directions, e.g. a hydraulic cylinder can extend and retract. If a collision is brought about by an extension movement (enlargement of the cylinder stroke), this direction of movement is blocked according to this variant of the invention.
- the collision direction can be saved in the automation of the coil box. In order to free the hydraulic cylinder, however, the opposite direction must not be blocked. After reaching a certain distance in the opposite direction of the collision, the collision direction stored in the coil box automation is deleted and the hydraulic cylinder can move in and out again in both directions of movement.
- the detection of the geometric dimensions of the movable and fixed parts of the coil box and/or the detection of the possible movements of the actuators of the coil box includes reading in a geometric data set, in particular a technical drawing.
- digitized drawing data is read directly into the digital model, so that no manual measurement of the geometry is required. This is done, for example, via a CAD exchange format.
- the kinematic relationships of the coil box are also usefully read in, particularly in the digital model. This is easily possible, for example, if the coil box was not only created in the form of a digital drawing, but also as a digital functional model with functional attributes for identifying the axes of rotation and degrees of freedom.
- the digital functional model differs from the digital model of the method according to the invention in particular by the collision check in real time during operation of the coil box.
- the required numerical values are not read from the imported drawing and entered, for example, in the geometry data record, but the distances are marked in the drawing by an engineer using a digital drawing program and an input device. These dates are subsequently written to an exchange file without transmission errors occurring. This is possible because the positions of the actuators (cylinder strokes) are not relevant for the definition of the geometry data.
- the method according to the invention includes tracking changes in movement, in particular the movement trajectory, of the moving parts of the coil box during operation over a predetermined period of time.
- the tracking of the movement changes is carried out in particular by the digital model while monitoring the movements of the moving parts of the coil box to detect collisions between moving and/or fixed parts of the coil box.
- the changes in movement in particular the respective movement trajectories. For example, if a roller moves in the direction of a machine interference edge and falls below a first alarm level, the method according to the invention, in particular the digital model, checks how the distance develops over time, e.g. from computing cycle to computing cycle.
- the distance can be in a transition to a tangential movement, so that the distance no longer decreases significantly and subsequently possibly even increases again.
- the method in particular the digital model, can delete the alarm again by falling below the first alarm level, even if the distance is still below the alarm level, since the distance is no longer decreasing and no collision is imminent.
- the object is also achieved according to the invention by a coil box of a metallurgical plant with continuous real-time collision monitoring, the coil box comprising moving and fixed parts and actuators for moving the moving parts of the coil box.
- the coil box according to the invention also includes automation for controlling the actuators, which implements the method according to the invention.

- FIG. 3 shows a side view of the coil box 100 according to the invention of a metallurgical plant, with real-time collision monitoring from FIG. 1 in a second operating state.
- FIG. 4 shows a view from above of the coil box 100 from FIG. 3 in the second operating state.
- the actuators 101, 102, 103, 104, 105, 106 were actuated by the automation of the coil box 100, so that the cylinder strokes H1 , H2, H3, H4, H5, H6 have changed to H11 , H21 , H31 , H41 , H51 , H61.
- the distances d1, d2, d3, d4, d8, d9, d10 from FIGS. 1 and 2 have changed to the distances d11, d21, d31, d41, d81, d91, d101 from FIGS. 3 and 4.
- the digital model which is integrated, for example, in the automation of the coil box 100, can be moved from all relevant moving points n (xi, yi, z) of the coil box 100 depending on the cylinder strokes H1, H2, H3, H4, H5, H6, H11 , H21, H31, H41, H51, H61 of the actuators 101, 102, 103, 104, 105, 106 determine the position. Furthermore, the position data of the fixed parts 1, 4, 9, 10, 20, 22, 40, 46 of the coil box 100 are known to the digital model.
- the corresponding distances between the points n and qd (k, i, j) are calculated from the position data (xi, yi, z,) and (Xj, yj, Zj), where k are the actuators 101, 102, 103, 104, 105, 106 represented.
- dl2
- the distances d3 and d4 or d31 and d41 can be calculated for example in FIGS. 1 to 4 by means of these equations.
- the current and shortest distance d (k, i, j) between points i and j is calculated for each geometry component k considered. Furthermore, the minimum permissible distance ds (k, i, j) is determined for a point (Xi, yi, Zi), for example read from a database.
- the radius R of a roller table roller is defined as the minimum distance ds (101, 5, 5) around the respective axis of rotation, identified by 5 in FIG.
- Rc is defined as ds (103, 26, 26) and ds (104, 26, 26).
- the digital model calculates the distances d (k, i, j) for each actuation of the actuators 101, 102, 103, 104, 105, 106 and, in a preferred variant, the same Rate of change Ad (k, i, j) for example between two computing cycles z with the time interval At.
- the smallest distance d (k, i, j) in the current cycle z is determined for each adjustment action, and the shortest distance in the following cycle is extrapolated with the help of the current distance and the rate of change d (t+At). If the current distance is smaller than the distance to be expected in the next journal, this distance is evaluated, otherwise the distance for the subsequent journal is evaluated.
- the distances d(k,i,j) for an actuator k can be dependent not only on the actuator k itself but also on the position of another actuator I. For example, if two points (xi, yi, zi) and (X2, y2, Z2) move towards each other and the two actuators k and I are involved, then the distance d (k, 1 , 2) for actuator k is evaluated and the same distance d (I, 1, 2) for actuator I. If there is a significant distance, a corresponding event (alarm, control action, etc.) is generated for both actuators k and I.
- the distance d9 between the insides of the side rails 34 for the cylinder strokes H5 and H6 of the respective actuators 105, 106 is greater than the width B of the bit 110 defined by the distance between points 42 and 44 .
- the distance d91 between the side guides 34 for the cylinder strokes H51 and H61 of the respective actuators 105, 106 is smaller than the width B of the chisel 110 between points 42 and 44.
- the distance d10 from Fig. 1 and 2 is therefore irrelevant and can be set to 00 . In this case it is sufficient to evaluate the distance d8.
- the digital model also evaluates the calculated minimum distances for a position H(k) of an actuator to determine whether an alarm or switching threshold has been undershot and, if necessary, triggers a corresponding alarm signal A(k) or switching signal S(k).
- the digital model stores the current direction of movement R(k) of the associated actuator k, in order to be able to distinguish the backward (collision-free) direction of movement from the direction of collision if the switching threshold is undershot. If the distance does not change or even increases, the digital model cancels an alarm triggered by falling below the alarm threshold, even if the alarm threshold is still undershot.
- FIGS. 5 shows a flow chart for calculations of the digital model and FIG. 6 the derivation of actions from the calculations.
- the digital model can calculate the rate of change Ad(k,i, j) (t) determine the relevant distance, i.e. whether the distance in the next magazine t+At will increase, decrease or remain the same. If the distance increases, the current distance d(k, i, j) (t) at time t is taken as a basis as a comparison value for the permissible distance ds(k, i, j). If the distance decreases, the value d(k, i, j) (t+At) for the next magazine t+At is taken as the basis for the comparison value for the permissible distance ds(k, i, j).
- FIG. 6 shows a flow chart of the actions of the control of a coil box derived from the calculations from FIG. 5 .
- the digital model also evaluates the calculated minimum distances for a position H(k) of an actuator to determine whether an alarm alarm (k, i, j) or switching threshold Stop (k, i, j) has been undershot and, if necessary, triggers a corresponding alarm signal A (k) or switching signal S(k) off (see Figure 6). For this purpose, the current distance d(k, i, j) is compared with the permissible distance ds(k, i, j).
