Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a metal roll mill, and more specifically,
The present invention relates to a metal rolling target shape adjusting device that gives target shape data to a shape control unit that controls the surface shape of metal and adjusts the surface shape.

(Prior art)

FIG. 12 shows a roll rolling mill 2 for rolling aluminum foil, which is an example of the background of the present invention. In aluminum foil rolling, about 700 to 1700 mm in width and several μm to several hundred μ in thickness wound on the entrance coil 50
m of the raw aluminum foil 51 is rolled by a pair of rolling rolls 52 at a speed of about 300 to 1200 m / min, and the thickness thereof is about 1/2 to 1
Reduced to / 3. Then, the rolled aluminum foil 53 is conveyed in the direction of arrow K by a constant tension generated by the rotation of the drive shaft of the output side coil 64 (FIG. 1), and wound around the output side coil 64.

For example, when a raw aluminum foil 51 having a thickness of several hundred μm is finally rolled into an aluminum foil 53 having a thickness of several μm, the rolling process is repeated several times, and the number of rolling is referred to as the number of passes. Can be

In the metal rolling in micron units as described above, the aluminum foil 53 “stretches” in the foil width direction (arrow L) despite its thickness being the same as shown in FIG. The "site" and the "stretched" site are remarkably present. That is, the extension portion 54 has a peak portion 56 and a valley portion 57 formed along the transport direction of the aluminum foil 53 (arrow K), and the tension portion 55 has a generally flat shape. Therefore, the aluminum foil shown in the figure
Reference numeral 53 denotes a state in which the central portion in the foil width direction (arrow L) is extended and its end is stretched.

The distribution of the degree of elongation and the degree of tension in the foil width direction (arrow L) is hereinafter referred to as the surface shape or actual shape of the aluminum foil 53. The surface shape has a great influence on the quality of the foil product, and in some cases, a large tension is applied to the tension portion 55, which causes the foil to break or wrinkle. And, as for the aluminum foil 53 as the final product, it is natural that a flat shape in which the elongation and tension occur uniformly is desired, but it is not necessarily a flat actual shape for each pass, but an intermediate shape. The shape of the aluminum foil 53 in the path is various.

The surface shape of the aluminum foil 53 as described above is
Can be controlled by changing the shape of As shown in FIGS. 12 to 14, the rolling roll 52 generates a bulge called a thermal crown due to heat generation during rolling and its heat conduction characteristics. The example shown in FIG.
Is bulging. Such a bulge, that is, a thermal crown, changes the surface shape of the aluminum foil 53 depending on the appearance location and the degree of bulge. In other words, the rolled aluminum foil 53 rolled at a portion where the degree of expansion of the thermal crown of the rolling roll 52 is large is in an elongated state. Therefore, the surface shape of the aluminum foil 53 is determined by the coolant 58 sprayed toward the rolling roll 52 to cool the rolling roll 52 (FIG. 1).
Temperature or injection amount in the width direction of the aluminum foil 53 (arrow L
(FIG. 13)).

Such shape control of the aluminum foil 53 is performed by the roll mill 2.
This is performed by the shape control unit 3 provided next to. That is, the shape control unit 3 is rotatably provided on the exit side of the rolling roll 52, and is configured to rotate the aluminum foil 53 from the inspection roll 4 including 36 elements 4e divided in the foil width direction (arrow L). The actual shape data of elongation and tension is input. Each element 4e has
Each of the piezoelectric elements (not shown) is embedded and functions as a sensor for detecting a pressing force applied to the outer peripheral surface of the element 4e.

Then, the aluminum foil 53 pressed against the element 4e and pulled in the transport direction (arrow K) by a constant tension is
When the extension portion 54 passes over the element 4e, the pressure contact force against the element 4e is small, and when the extension portion 55 passes, it is detected large.

Therefore, as shown in FIG. 14, the actual shape of the aluminum foil 53 is expressed as a distribution (actual shape data) of the elongation rate in the width direction obtained by converting the pressing force data detected from each element 4e. In the case shown in the figure, the quota portion a of the rolling roll 52 is excessively bulged, so that cooling of that portion is promoted,
Target shape data is set so that heat is stored in the central portion of 52 and both ends thereof.

The shape control unit 3 performs a comparison operation between the actual shape data and target shape data input in advance, and the actual shape data is injected toward a portion of a rolling roll corresponding to the element 4e having a higher elongation. Increase the amount of coolant 58. The upper coolant 58 is provided on the entry side of the rolling roll 52 and is sprayed from a spray pipe 59 shown in FIG. 9 which is divided and sprayed in the foil width direction (arrow L).

Thereby, the thermal crown of the rolling roll 52 is relieved,
The part of the aluminum foil 53 corresponding to the quarter part a is deformed toward the tension state. If the actual shape data has a lower elongation, the reverse operation is performed. In the target shape data, the elongation obtained from the element 4e corresponding to the quarter portion a is often set to 0 so as to promote cooling of the quarter portion a of the rolling roll 52.

[Problems to be solved by the invention]

However, in the above-described roll rolling mill 2, the actual shape of the obtained aluminum foil 53 slightly changes due to various causes. For example, even when the raw aluminum foil 51 is rolled using the exactly same roll mill 2, the operating conditions such as the heat balance of the roll 52, its surface shape, temperature, the shape of the aluminum foil ingot, etc. It changes every moment. Further, the correlation between the actual shape and the operating conditions is difficult to formulate as a numerical model, and has not been sufficiently elucidated. Therefore, there are many parts related to the rolling of the aluminum foil 53 on the order of μm depending on the skill or intuition of the operator.

Also, when changing the target shape data set so as to obtain the aluminum foil 53 having a predetermined actual shape, there are also parts that have not been clarified similarly. For example, even when trying to change the actual shape in which the same or similar problem shape occurs, the procedure or method for changing the actual shape is often different, and in order to solve the problem shape, A process similar to trial and error is required to obtain the target shape of.

However, even if inference means based on general rules is employed as a process similar to the trial and error, if the available operating condition data and the like remain unchanged, inference for appropriately changing the actual shape is performed. The result is the same result repeatedly calculated. In other words, if the target shape obtained by the inference means does not show an effect on a certain problem shape and the same problematic shape continues, the target shape obtained by the inference again changes from the previous invalid inference result. Because there is no place,
There is a problem that an appropriate target shape cannot be obtained.

Therefore, an object of the present invention is to invalidate the target shape obtained by the inference rule with respect to the problem shape that appears in the actual shape of the strip-shaped metal stretched by the roll rolling mill, even if the target shape obtained by the inference rule has no effect. The inference rules that derive the target shape are not repeatedly applied, and the target shape given to the shape control unit and required to achieve the control target is automatically and appropriately changed and set according to the change in the operating conditions. It is an object of the present invention to provide a metal rolling target shape adjusting device capable of performing the above-described steps.

[Means for solving the problem]

In order to achieve the above object, the means adopted by the present invention is that the gist is that the target shape change data is sent to a shape control unit that controls the surface shape in the width direction of a strip-shaped metal stretched by a roll rolling mill. In the metal rolling shape adjusting apparatus for adjusting the surface shape by giving the sensor, a sensor for detecting the actual shape of elongation and tension at the time of rolling, storage means for storing the target shape change data, and before and after controlling the actual shape data Priority determining means for determining the priority of the target shape change data according to the control condition by the change of, and selecting the target shape change data having a high priority according to the current actual shape data under control and the control condition, A metal rolling shape adjusting device according to the above aspect, further comprising: an arithmetic unit that outputs the shape to the shape control unit.

Here, the actual shape data may be an output value from a sensor, or may be a concept representing an elongation / tension shape as described in the following embodiments.

[Action]

According to the present invention, when rolling metal with a roll rolling mill, the shape control unit controls the coolant based on the target shape required to achieve the control target given from the metal rolling target shape adjusting device. By doing so, the surface shape (actual shape) of the metal in the width direction is adjusted.
Therefore, in the metal rolling target shape adjusting device, the importance calculating means automatically calculates the control target and its importance based on the actual shape data such as elongation and tension detected from the sensor on the roll rolling mill side. The control target selecting means selects the control target having the highest importance, for example, according to the importance. Then, the inference rule stored in the rule storage means for achieving the selected control target is executed. Subsequently, depending on whether the actual shape data before and after executing the inference rule has changed, that is, whether the actual shape data has changed in a direction to achieve the control target, the priority determination means determines the above according to the control condition at that time. Determine the priority of the inference rules. For example, if the actual shape data obtained based on the inference result of this time is improved compared to the previous one, the priority of the inference rule used at that time is determined by upgrading, otherwise, the The priority of inference rules is determined by downgrading. Then, an inference rule having a high priority is selected by the calculating means in accordance with the current actual shape data under control and the control condition, and, for example, a target shape obtained by the selected inference rule is output to the shape control unit. . Thereby, even if the target shape does not show an effect on the current actual shape data, the invalid rule derived from such a target shape is not repeatedly applied from the next time. As a result, the target shape is
In order to stably obtain a metal having a predetermined actual shape, the setting is automatically and appropriately changed and set.

In the following description, the same elements as those of the rolling mill 2 shown in FIGS. 12 to 14 are denoted by the same reference numerals, and the description thereof will be omitted.

Further, the following embodiments are merely examples embodying the present invention, and do not limit the technical scope of the present invention.

In the present embodiment, an aluminum foil rolling target shape adjusting device 1
As shown in FIGS. 1 and 2, the shape control unit 3 that controls the injection amount or the temperature of the coolant 58 so as to adjust the actual shape of the aluminum foil 53 has target shape data as a guide for the control. And rolling data from the shape control unit 3 are input.

As a method of adjusting the actual shape of the aluminum foil 53, there is also a method of controlling the push-up force of a push-up roll 60 for urging the lower roll 52 upward toward the upper roll 52, In the present embodiment, only the control of the coolant 58 will be described below.

In the aluminum foil rolling target shape adjusting device 1, the inspection roll 4 is provided with an extension portion 54 of the aluminum foil 53 at the time of rolling.
And a set of sensors for detecting actual shape data indicating the stretched portion 55 (FIG. 13), which is provided on the downstream side in the transport direction (arrow K) of the rolling roll 52, and is provided via the shape control unit 3. Is output to the rolling data collection unit 7 (FIG. 2). The rolling data collection unit 7 writes rolling data as operating conditions to be transferred from the shape control unit 3 at every predetermined time interval (Table 1) in the working memory M ₁ At the same time, the rolling state analysis unit 8 is activated. Rolling status analyzing unit 8, the actual shape data input from the work memory M _1, the actual shape classification items and the specific methods are stored in the rolled condition analysis knowledge base D ₁ (Figure 3) and compared with reference to the Te, the actual shape is derived by a function to identify the one of the actual shape classification items in some confidence, and stores the classification items and the confidence to the working memory M _2. For example, four elements from the end where the aluminum foil 53 is placed
The ratio in the range of the actual shape data input from 4e, the difference beta ₂ of the minimum value of the elongation index difference alpha ₂ of the most high growth sites and end of the index to the maximum value of the elongation in the entire solid shape data β ₂ / α
_{When 2} exceeds a predetermined set value, the actual shape at this time is
The actual shape classification item is specified as “edge extension”, and a certainty factor from 0 to 1 is added according to the value of the ratio.

In this way, the rolling condition analysis unit 8 determines the actual shape classification item of the aluminum foil 53 and the certainty thereof, and the work memory M ₂
Written to

The control target data (shape change target (FIG. 4) and its importance), which is a key in appropriately setting or changing the target shape, is supplied to the roll mill 2 by the operator 5 in the control target generator 9. or is input from the terminal 6, or on the basis of the working memory M actual shape classification items and the rolling status data of the confidence or the like in ₂ is automatically generated. In this automatic generation, “the operation method (such as“ rolling by extending the end greatly in a predetermined pass ”)” or “if the input by the operator 5 and the automatically generated one conflict, the rule such "give priority to input information of the operator is applied with reference to the control target setting knowledge base D _2.

For example, if the detected actual shape data includes “edge extension” as in the above example and the confidence at that time is 0.8, five shape change targets are set in order to eliminate “edge extension”. Is selected, and the importance corresponding to the certainty factor (0.8) is given to the selected shape change target. Then, the shape change target and its importance are stored in the working memory M _3. That is, the control target generator 9 is an importance calculating means.

Rolling data including the current target shape data and the current actual shape data, and the rolling status data including the extracted actual shape classification items and the degree of confirmation thereof, processed as described above. And the control target data including the shape change target and its importance are transferred from the work memories M ₁ , M ₂ , M ₃ to the action candidate inference unit 11, respectively. Action candidate inference unit 11, and the data transferred, collates the condition part of the rule to the action inference knowledgebase D ₃ is stored, the matching result,
A rule that satisfies that all the condition parts are true is extracted, and the target shape change data (FIG. 4,
(Hereinafter referred to as action). The rule is expressed in the form of “if [condition part], if it is [conclusion part]”, and is expressed by a logical product as shown below.

If [control target data] and [rolling data, rolling state data], then [designation of target shape adjustment parameter and its change degree (action)] For example, as shown in FIG. ,
If the actual shape of the aluminum foil 53 is specified as quarter extension, and there is no zero below the portion with the largest extension near the quota at that time, the position of the zero point is set below the portion with the largest extension near the quarter. Is stored.

Further, as shown in FIG.
There are several types of action candidates with priorities added to the shape change target. Then, when a certain shape change target is selected, the action having the highest priority is executed. The priority is not fixed and is checked for each inference. For example, action candidate inference unit 11
When inference is performed in respect any shape change target, which action it has adopted is stored in the working memory M _5, at action effect evaluation section 10 at the time of the next inference, the previous shape change target as described below Whether the control has been achieved (evaluation of the effect) is determined by comparing the importance of the previous control with the current control.

Subsequently, the actions specified as a candidate in the action candidate inference unit 11, as shown in Figure 6, when it is registered in the working memory M _5, the action inference knowledgebase
In accordance with the stored check routine to D _3, those higher efficacy are sorted. In the check tree shown in the figure, first, whether the rule that matches the shape change target and the currently selected shape change target antecedent is registered in the knowledge base D ₃ is checked in case C _1. Case C ₁
If true, the process proceeds to check the strings attached according to the rolling conditions in the condition part of the rule in the case C _3. If not corresponding to the case C _1, is checked on whether the case C ₂ no action candidates relating to this selected shape change targets other rules.

If applicable to the case C _2, the selection of actions are more healed on changing the priority of the rule. If there is the action candidate, the process ends.

If not corresponding to the case C _2, that is, when all the condition part including incidental condition does not match, the rule is removed from the main area of the rule set of actions inference knowledgebase D ₃ to save area. If the incidental conditions are satisfied, case C ₄
In the action of the rule that the condition part is satisfied all is whether the effect was not observed if there is that it has been applied in the past, that is, whether they are registered in the current working memory M ₄ is checked. And case C ₄
, The rule is removed from the rule set. If this is not the case C _4, the presence of actions conflicting with each other is checked in case C _5. Already among the actions that are registered with the working memory M _5, if there is an action that is inconsistent with the action of the current in check,
The rule that sets the action with the greater importance of the shape change target set in the condition part of the rule is the working memory
It is registered in the M _5, the importance of the smaller rules you have set the action of is removed from or above rule set is deleted from the working memory M _5. If not applicable to the case C _5, i.e., when the respective actions are consistent, whether the action shape change target is the same has already been registered in the working memory M ₅ is checked in case C _6. If applicable to the case C _6, check whether there is a difference in the priorities of each action (Case C _7), if there is a difference in priority, only the action of the larger priority is the working memory M ₅ left, the smaller action of priority is erased from the working memory M _5. When there is no difference in priority, both actions are registered together in the working memory M _5.

Thus, by the check routine, working inconsistency between action candidate memory M ₅ already about to be newly registered as action candidates registered, priority, efficacy results are checked, the target shape data The relevance of the action to be applied to the change is maintained.

Subsequently, the work action is registered in the memory M ₅ and the degree, that is, "raising the end level, the degree 0.8"
Is transferred to the target shape generation unit 12.

The target shape generation unit 12 changes the values of the target shape adjustment parameters shown in Table 2 and FIGS. 7A to 7D based on the target shape change data. Let it. For example, when the above-mentioned action is “raise the end level, the degree is 0.8”, the value of the target shape adjustment parameter a ₁ related to the elongation rate of the end is determined according to the degree of the action. The change is set, and the target shape data changes. Further, the shape control unit 3 determines the coolant 58 of the roll mill 2 based on the input target shape data after the change.
To control the amount of Then, the rolling data including the actual shape data newly obtained this time is input to the rolling data collection unit 7, and the same processing as the previous time is repeated. That is, the shape change target for the current actual shape and its importance are calculated by the control target generation unit 9 and compared with the previous one in the action effect evaluation 10, respectively. As a result, if the current target shape data changed based on the previous shape change target and its importance is determined to be valid in the action effect evaluation unit 10, that is, the importance is set to a value lower than the previous value. If so, the action taken was valid,
Priority stored the action in the action inference knowledge base D ₃ is moved forward by the action candidate inference section 11. Conversely, if it is determined to be invalid, and rules which infers selected last applied in action and the action was not effective it is stored in the working memory M _4.

For example, as for the shape change target shown in FIG. 4, the last time "I want to extend the end" is determined to be 0 based on the rolling state data from the rolling state analyzing section 8 or the input data from the operator 5.
If it is determined in step 6, the highest priority "increase the level of the edge (priority 1)" among the actions associated with it is selected, and the level of the edge (elongation rate) according to the importance level 0.6. target shape data raised is output to the shape control unit 3, at the same time the applied target shape data, shape change target, its severity (0.6), the action, and its priority (1) is stored in the working memory M ₅ Is done. Then, when the shape change target “I want to extend the end” is selected with the importance of 0.6 or more at the time of determining the shape change target of the present time, the edge tension state of the actual shape in question is improved. In many cases, the last applied action was invalid. Conversely, if "I want to extend the end" is selected this time with an importance of less than 0.6, it is determined that the previous action was effective.

Thus, at action candidate inference unit 11, when selecting the current action candidates, disabled action and importance of the previous stored in the working memory M _4, is referenced priority etc., the priority of the disabled action Along with the downgrade, it is inevitably advanced and another action determined to be appropriate is applied to the next appropriate change of the target shape.

Thereby, even if the target shape obtained from the aluminum foil rolling target shape adjusting device 1 does not show an effect on the actual shape and the problematic actual shape continues, in the next inference, Despite having the same shape change target, a different one from this action is selected. Thereby, the invalid shape is not repeatedly applied, and the actual shape is appropriately changed.

FIG. 8 shows a specific example in which the above inference is repeated. For example, the shape change target E _1, which is calculated from the actual shape data included in the rolling data that, when the importance level is "want strung quota" is 0.8, the first inference E ₂ is executed And the action candidate at that time is (A1)
Increasing the width of the zero point (A2) would move the zero point outward. Here, the high-priority action A1 is applied, and the target shape before and after the change is changed by the inference result E ₃
Was as shown in FIG.

However, when evaluating the effect of action A1, E ₁
Was not less than 0.8, and its effect was not observed.

Therefore, the rule to derive the above action A1 is stored in the work memory M ₄ as was ineffective.

Then, apply the next highest priority action A2 to 2
Times eyes of inference E ₄ is executed. As a result, it is determined that the quota growth has been improved, and the priority of the action A2 is upgraded from that of the action A1.

As described above, in the aluminum foil rolling target shape adjusting device 1 according to the present embodiment, the shape change target having the highest importance is determined as the action candidate in accordance with the importance of the shape change target calculated by the control target generator 9. Selected by the inference unit 11.
Then, in order to achieve the above selected shape change target, the action inference knowledgebase D ₃ to stored in and inference rules, for example, if a plurality of presence, each of the priority is given in advance. Therefore, the action candidate inference unit 11 (arithmetic means) performs inference with a high-priority action according to the current actual shape data under control and the control condition so as to realize the ideal actual shape at that time. A rule is selected and output to the shape controller 3 via the target shape generator 12. Further, the action effect evaluation unit 10
Evaluates the change in the actual shape data before and after executing the action of the inference rule output to the shape control unit 3, that is, whether the shape change target has been achieved. Based on the evaluation result, the action candidate inference unit 11 Determines the priority of the action of the inference rule according to the control condition at that time.

That is, the action effect evaluation unit 10 and the action candidate inference unit 11 are priority determining means.

The aluminum foil rolling target shape adjusting device 1 as described above,
As shown in FIG. 9, the operation is started by the operator 5 pressing the key from the rolling mill terminal 6 (step 21). Subsequently, the operator 5 inputs the shape change target information together with the importance according to the input menu (FIG. 10) displayed on the screen of the terminal 6 (step 22).

Accordingly, the aluminum foil rolling target shape adjusting device 1
Analyzes the rolling data transferred from the shape controller 3 (step 23), creates an appropriate target shape by inference (step 24), and displays the target shape before and after the correction (FIG. 11) on the screen. At the same time, the corrected target shape data is output to the roll mill 2 via the shape control unit 3 (step 25). Then, it was evaluated whether the corrected target shape was valid for the problematic actual shape (step 2).
6) Waiting for input by the operator 5.

At this time, the shape change target and its importance are also automatically generated in the aluminum foil rolling target shape adjusting device 1. However, when the target is inconsistent with the input by the operator 5, the respective importance is determined. The shape change target may be generated based on a rule that gives priority to any one of a high object, an object input by the operator 5, and a result of a shape judgment calculated using the actual shape classification items.

The aluminum foil rolling target shape adjusting device 1 employs an element 4e in which a piezoelectric element is embedded as a sensor for detecting actual shape data of elongation and tension at the time of rolling.
A plurality of air-bearing elements whose appearance is substantially the same as the element 4e may be used as the sensor, and the actual shape data may be detected based on a change in the air pressure.

〔The invention's effect〕

As described above, the present invention provides target shape change data to a shape control unit that controls the surface shape in the width direction of a strip-shaped metal stretched by a roll rolling mill, and adjusts the surface shape by giving target shape change data. In the apparatus, a sensor for detecting the actual shape of elongation / tension at the time of rolling, storage means for storing the target shape change data, and a target shape change data corresponding to a control condition by a change before and after the control of the actual shape data. Priority determining means for determining priority, and calculating means for selecting high-priority target shape change data according to the current actual shape data under control and control conditions, and outputting the selected target shape change data to the shape control unit. Since the metal rolling shape adjusting device is characterized in that the target shape obtained by the selected inference rule corresponds to the problem shape appearing in the actual shape of the metal. Even if no effect, is not to apply repeatedly inference rules to derive the above invalid target shape. At the same time, effective inference rules are applied with priority. Thereby, the target shape can be automatically and appropriately changed and set in accordance with a change in the operating condition. As a result, a metal having a desired actual shape can be stably produced.
