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 shape adjusting device that gives target shape data to a shape control unit that controls a metal surface shape and adjusts the surface shape.

(Prior art)

FIG. 9 shows a roll 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. 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 54 (FIG. 1), and is wound around the output side coil 54.

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 above-described metal rolling in units of microns, as shown in FIG. 10, the aluminum foil 53 has a portion that “extends” in the foil width direction (arrow L) despite its thickness being the same. And "stretched" parts 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. Further, the stretched portion 54 causes wrinkles. 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. 9 to 11, the rolling roll 52 generates a bulge called a thermal crown due to heat generation during rolling and its heat conduction characteristics. In FIG. 11, the thermal crown whose portion a is expanded changes the surface shape of the aluminum foil 53 depending on the appearance location and the degree of expansion. That is, rolling roll
In the aluminum foil 53 rolled at the portion where the degree of expansion of the thermal crown 52 is large, the rolled portion is in an elongated state. Therefore, the shape of the aluminum foil 53 is such that the coolant 58 (the first
It can be controlled by changing the temperature or the injection amount in the figure in the width direction of the aluminum foil 53 (arrow L). The coolant generally refers to a cooling medium injected to the rolling roll 52 as described above.

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, the rolling delivery side is provided rotatably on the roll 52, the foil width direction (arrow L) consisting of 36 to split the element 4 _e to the inspection roll 4, aluminum foil 53 The actual shape data of the elongation and tension of is input. Each element _4e has one piezoelectric element (not shown) embedded therein.
4 _Acts as a sensor to detect the pressing force applied to the outer peripheral surface of _e .

Then, placed on the element 4 _e, certain aluminum foil 53 is pulled in the conveying direction (arrow K) by tension, pressure against the element 4 _e when the elongation portion 54 passes over the element 4 _e The force is small, and conversely, large when the tension portion 55 passes.

Therefore, the actual shape of the aluminum foil 53, as shown in FIG. 11, expressed as a width direction of the distribution of elongation obtained by converting the pressure contact force data detected from the respective elements 4 _e. In the case shown in the drawing, cooling of the quarter portion a of the rolling roll 52 is promoted, and heat is stored in the central portion of the rolling roll 52 and both ends thereof,
This shows an example in which a predetermined target has not been achieved in the actual shape despite the target shape being set.

The shape control unit 3 compares the actual shape data with the previously input target shape data, and injects the actual shape data toward the portion of the rolling roll corresponding to the element 4 _e having a higher elongation. Increase the amount of coolant 58 that is used. The 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).

At this time, the elongation value of the target shape corresponding to the i-th element 4 _e is divided into 36 in the foil width direction (arrow L), and the elongation value of the actual shape is y (i). ).
Furthermore, assuming that the aluminum foil 53 is placed on all the elements 4 _e, the average of the growth rate corresponding to all elements 4 _e And then, the deviation from the average value in the i-th element _{4 e, (i) = x} (i) -, (i) = y (i) - When the target shape of the i-th element 4 _e The shape error of the actual shape data with respect to the data is represented by e (i) = (i)-(i).

In addition, the control of the injection amount and the temperature of the coolant 58 has been conventionally performed by a shape error e in a certain element 4 _e .
This has been done based on (i). For example, the transfer function of the injection amount p (i) of the coolant 58 corresponding to the i-th element 4 _e is Pi = k (1+ (1 / T _is )) Ei where K; proportional gain Pi; p (i) Lai conversion value of Ei; e (i) Laplace conversion value Ti; Integration time (Non-linear control element is omitted) It is expressed by the general formula of PI operation shown by the following formula. p (i) is controlled.

Thereby, the thermal crown of the rolling roll 52 is relieved,
The part of the aluminum foil 53 with respect 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.

[Problems to be solved by the invention]

However, in the shape control unit 3 as described above,
The actual shape of the aluminum foil 53 is determined by the operator 5 by manually controlling the injection amount and temperature of the coolant 58 (FIG. 1) injected toward the portion of the rolling roll 52 corresponding to the element 4 _e of the divided detection roll 4. Is controlled by being corrected by changing in or by adjusting by a control system based on the P1 operation.
It is not possible to follow the specific heat distribution generated in the roll 52, and it is not possible to sufficiently control the thermal crown that has appeared on the rolling roll 52. For this reason, the conventional control as described above may not be able to cope with a portion requiring control such as the thermal crown.

Accordingly, an object of the present invention is to control a control required portion more effectively by controlling a neighboring portion adjacent to the control portion so as to stably produce a metal having a desired actual shape. An object of the present invention is to provide a metal rolling shape adjusting device that can be made.

[Means for solving the problem]

Means adopted by the present invention to achieve the above object is to provide target shape data to a shape control unit that controls a surface shape in a width direction of a metal in a band extended by a roll rolling mill. In the metal rolling shape adjusting device for adjusting the surface shape, it is necessary to control the metal by comparing and judging a sensor for detecting the actual shape data of elongation and tension at the time of rolling and the actual shape data with an arbitrary threshold value. A metal rolling shape adjusting device according to a point including a shape determining unit for extracting a portion, and a control condition intervention unit for changing a coolant corresponding to an adjacent portion adjacent to the control necessary portion.

[Action]

According to the present invention, when the metal is rolled by the roll rolling mill, the surface shape (actual shape) in the width direction of the metal is determined by the shape control unit automatically or manually given from the metal rolling shape adjusting device. The adjustment is performed by controlling the coolant based on the data. At this time, the metal rolling shape adjusting device compares the actual shape data such as elongation and tension detected from the sensor on the roll mill side with a threshold value arbitrarily set to specify and determine the actual shape. Then, a comparison judgment is made to extract a portion of the metal requiring control. The control condition of the coolant corresponding to the adjacent portion adjacent to the control necessary portion is changed by the control condition intervention unit. Thereby, the shape of the portion of the metal that needs to be controlled is more effectively controlled because the adjacent portion is relatively controlled.

In the following description, elements common to those of the aluminum foil rolling mill 2 shown in FIG. 9 to FIG.

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, the aluminum foil rolling shape adjusting device 1 includes:
As shown in FIGS. 1 and 2, target shape data serving as a guide for the control is output to the shape control unit 3 which controls the injection amount or the temperature of the coolant 58 so as to adjust the actual shape of the aluminum foil 53. At the same time, rolling data is input from the shape control unit 3.

In the aluminum foil rolling shape adjusting apparatus 1, the inspection roll 4 is a roll of rolling rolls as an aggregate of sensors for detecting actual shape data indicating the stretched portion 54 and the stretched portion 55 (FIG. 10) of the aluminum foil 53 at the time of rolling. The rolling data including the actual shape data is provided to the data collection unit 7 via the shape control unit 3 at the downstream side in the transport direction (arrow K) of 52 (FIG. 2).
Output to Data collection unit 7 writes the rolling data 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 breaking unit 8 is activated. Rolling status Kaiori unit 8 compares 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 status Kaiori knowledge base D ₁ (third view) Judgment, the actual shape, at a certainty degree derived by an appropriate function, specified in any of the actual shape classification items,
The said classification items and their confidence is stored into the work memory M _2. For example, within the range of the actual shape data input from the four elements 4 _e from the end on which the aluminum foil 53 is placed, the elongation difference α ₂ between the part having the highest elongation and the end and the entire actual shape data Β ₂ between the difference between the maximum and minimum values of elongation at β ₂
If / α ₂ exceeds an arbitrarily set threshold value, the actual shape at this time is identified as the actual shape classification item is “edge elongation”, and the actual shape classification item is 0 to 1 depending on the value of the ratio. Confidence is added.

As described above, in the rolling status unfolding unit 8, the actual shape classification item of the aluminum foil 53, its certainty factor, and the zero point set in the target shape are the highest elongation rates of the actual shape corresponding to the quarter part a of the rolling roll 52. validity of whether zeros are consistent with high sites are confirmed and written into the working memory M _2.
Further, simultaneously stored rolled condition data such as the value of the later-described target shape adjustment parameter used to set the target shape at this point be established, to the working memory M _1. The validity of the above-mentioned zero point is a concept necessary for controlling the stretchable portion to be stretched in view of the rolling characteristics. That is,
Usually, the above-mentioned quarter portion is a portion which enters only about 1/4 of the width from the end of the rolled material, and is a portion where the heat of the roll easily accumulates (heat-expands easily), and thus becomes the elongate shape most easily. In shape control, the value of the target shape is set to the lowest value (that is, set to 0) in order to extend this portion. This is why the target shape value of the quota section is called a zero point. Normally, the zero point of the target shape is set so as to coincide with the extension portion of the quarter portion. However, the zero point may be shifted depending on the rolled material, the rolling condition, and the like. The determination of whether or not to correct it is the above-mentioned "validity of zero point". If the zero point is not valid, that is, if it is inappropriate, it is necessary to correct this, and the elongation rate at the maximum elongation position is set to zero. Such a target shape is output.

Then, the control target data (shape change target (FIG. 4) and its importance), which is a key in appropriately changing the target shape, is stored in the control target generator 9 in the working memory M _2.
It is generated based on the rolling condition data of the inner, working memory M ₃
Is stored.

The rolling data, rolling state data, and control target data processed as described above are transferred from the work memories M ₁ , M ₂ , and 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 result of the collation, the rule which satisfies the condition part are all true Extract the target shape change action in the conclusion part of the rule (Fig. 4, hereinafter called action)
Select The rule is expressed in the form of "if [condition part], then [conclusion part]", and is expressed in the form of the following logical product.

If [control target data condition] and [rolling data condition, rolling condition data condition], then [designation of target shape adjustment parameter and its change degree (action)] That is, as shown in FIG. In Example 1, when the actual shape of the aluminum foil 53 is specified as the quarter extension, and there is no zero below the largest portion of the extension near the quarter portion, "the position of the zero point is determined as the extension near the quarter portion. A rule that specifies an action such as "bring under a large part" is stored.

Here, in order to deepen the understanding of the present invention, the importance is further described. Usually, a plurality of actual shape classification items are specified for one actual shape, and a plurality of actions are extracted to solve the problem. In this case, there are cases where actions in the opposite direction are juxtaposed. To deal with such a case, use the "importance"
Is used.

Explaining in a specific example, each action is associated with a goal (for example, “I want to make an end”) and its importance (for example, “0.75”). Now site X
The action of increasing the coolant (Al)
It is assumed that the action (A2) of reducing is parallel. In this case, ・ The control target of Al and its importance are “correct quota growth”
Suppose that the control target of A2 and its importance were 0.6 in "Correcting beam". In this case, priority is given to the target “correction of quota growth”, which is of high importance.
Reject. However, as it is, "fixing the lining"
Is not realized. If there are multiple actions registered in the knowledge base that can achieve the same goal (in this case, “fixing of the lining”) (for example, A3 “Reduce the coolant in the area adjacent to area X”), In some cases, the two goals can be realized without adopting the opposite directions. It is “priority” described in FIG. 4 that determines an action to be applied in the same goal.

In this case, the priority of A2 is higher than that of A3, so the application of A2 will be considered before A3, but the reverse action to achieve the more important goal "correct quota growth" Al is adopted. Therefore, A2 is rejected, but then action A3, which has a lower priority but is effective for the goal of “fixing the lining”, will be adopted as an alternative.

As the shape change target, as shown in FIG. 4, several types of action candidates with priority added to one shape change target are prepared. 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, if the inference in action candidate inference unit 11 is executed, with respect to which the shape change target, which action it has adopted is stored in the working memory M _5, at action effect evaluation section 10 at the next inference, the last reshaping Whether or not the goal has been achieved is determined by comparing the priorities before and after. As a result, if the goal has been achieved, that is, if the degree of importance is lower than the last time, the priority is raised assuming that the adopted action is effective. Conversely, if the goal has not been achieved, its priority is lowered.

Therefore, even if the target shape obtained by the aluminum foil rolling shape adjusting device 1 does not show an effect on the actual shape and the problematic actual shape continues, in the next inference, Despite 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.

Then, at action candidate inference unit 11, the actions specified as a candidate, the work when it is registered in the memory M _5, in accordance with the stored check routine the action inference knowledgebase D _3, already in the working memory M ₅ The inconsistency, priority, and effectiveness record between the registered action candidate and the newly registered action candidate are checked, and the validity and consistency of the action to be applied to the change of the target shape are checked. Maintenance is made.

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

The target shape generator 12 changes the values of the target shape adjustment parameters shown in Table 2 and FIGS. 6 (a) to 6 (d) based on the target shape change data, and Change in _e units.

For example, the coolant 58 is controlled with respect to an actual shape control required portion corresponding to the element 4 _e of the i-th memory. 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. 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 candidate evaluation unit 10, respectively. As a result, if the current target shape, which has been changed based on the previous shape change target and its importance, is determined to be invalid by the action effect evaluation unit 10, the action applied previously and not effective is determined. and rules deduced selection of the action is stored in the working memory M _4.
Then, at action candidate inference unit 11, last stored in the working memory M ₄ when selecting an action candidates invalid action and that rule is referred to this time, with the priority of the disabled action is downgraded, inevitably Then, another action determined to be appropriate is applied and applied to the next appropriate change of the target shape.

So far, the shape control of the aluminum foil 53 at the control required portion has been described, but the shape control of the adjacent portion adjacent to the control required portion will be described below.

Here, as shown in FIG. 7 as an example, the proximity part adjacent to the control required part is a part where the shape error e (i) of the real shape shown by the solid line with respect to the target shape shown by the dotted line reverses the sign ( B ₁ , B ₂ , B ₅ , B ₆ ), and besides, for example, a site corresponding to the element 4 _e separated from the control-needed site (site for the i-th element) by one or three. There is also.

In contrast to the control amount p (i) of the coolant 58 injected onto the rolling roll 52 corresponding to the control-required portion, the control amount q (i) corresponding to the adjacent portion is used as a correction amount for the main control as the actual shape. Is applied in consideration of the overall balance of.
That is, p (i) is And Here, the control amount q (i) of the coolant 58 is stored in the action candidate inference unit 11 in the action inference knowledge base.
It is determined according to a predetermined rule stored in the D _3. For example, "to eliminate the elongation extending the proximity portion are stretched adjacent to the site extending."<Rule> rule applies to, e (i-1)> 0 ( left side in the drawing of the site B ₁₎ and e (i) <0 for portions corresponding to the i-th element 4 _e such as a (part B ₁ of the drawing on the right),
The control amount q (i) is given by the following equation.

q (i) = α ₉ · p (i) (where α ₉ <0), whereby a stretched adjacent portion (e (i)) adjacent to the extended portion (e (i−1)> 0) <0) is the coolant 58
Of the fuel injection is decreased accompanyingly.

In addition, for example, the rule of <Rule>"If the temperature of the coolant controlled corresponding to the part that transitions from the part stretched at the end to the part of quarter elongation is low, increase it" may be applied. .

That, e (i-1) the site B ₅ as a border <0 and e
(I) the (i-1) th element such that> 0
4 the temperature of the coolant 58 is injected into the site (the left side in the drawing of the site B ₅₎ corresponding to _e is changed higher. This is because the coolant amount to the quarter portion (for example, B _{3 in the} figure) determined to be the control necessary portion is usually the maximum amount and the coolant having the low temperature is supplied. th site corresponding to the element 4 _e of is to eliminate that it is subcooled. Thereby, the end of the actual shape is elongated and the quarter is stretched, so that a relatively flat aluminum foil 53 can be obtained.

The control flow as described above will be described with reference to the flowchart shown in FIG.

When the process is started, from the rolling conditions Kaiori portion 8 and the rolling conditions Kaiori knowledge base D _1, from the consisting shape determination unit 1a, is divided requiring portion (foil width adjustment to the injection quantity or temperature of the coolant 58 One of the elements 4 _e ) is extracted (step 30), and the elongation / tension of the shape is determined (steps 31 and 32).

Furthermore, the control condition intervention unit 1 _b made of the action candidate inference unit 11 and the action inference knowledgebase D _3, adjacent portion adjacent to the adjustment required site is determined whether there (step 33 and 38), the proximity site If the shape is in the stretched state, the injection amount of the coolant 58 is increased, and if the shape is tight, it is decreased (steps 34, 35, 39, 40). At this time, it is needless to say that the same control is performed on the portion requiring adjustment. Then, the effect of the above-described intervention control is determined (steps 36, 37, 41, 42), and after a predetermined time has elapsed, the operated data is returned to the initial state.

The aluminum foil rolling shape adjusting device 1 is a sensor for detecting actual shape data of elongation and tension at the time of rolling.
Piezoelectric element employing a buried element 4 _e, but a plurality of air-bearing element to the element 4 _e and appearance substantially one substitute as the sensor, the actual shape data based on a change in the air pressure It can also be detected. Further, the control target is not limited to the aluminum foil 53, but can be applied to copper and other metals.
