In the extensible member 16 of accepting command signal, make adjuster (the omitting diagram) work of hydraulic pressure or air pressure, bar portion 23 presses to support unit 15 with set power and batches reel 10 sides.
Here, consider former thereby make the tension force situation jumpy of rolling stock 3 because of certain.The pushing force that applies to intermediate calender rolls 13 if the tension force of rolling stock 3 sharply changes then can be pressed into the intermediate calender rolls 3 that loses dynamic balance for certain, and for example, there is the possibility on the surface of contact rolling stocks 3 in intermediate calender rolls 3.
So in this control method, in tension force calculating part 26, tension force calculating part 26 detects the variation of the tension force of rolling stock 3, extension and contraction control portion 25 cooperates the tension variation that detects and controls extensible member 16.That is, under the situation that the tension force of rolling stock 3 diminishes, interlock with it reduces the pushing force of intermediate calender rolls 3.Under the tension force of rolling stock 3 became big situation, interlock with it increased the pushing force of intermediate calender rolls 3.
Like this, intermediate calender rolls 13 to roll angle (rolling stock 3 of the input side of the roller 13 that mediates and be in rolling stock 3 angulations of outlet side) irrespectively always certain with the variation of tension force, even and tension variation do not have possible that intermediate calender rolls 3 contacts with the surface of the rolling stock 3 that batches reel 10 yet.
On the other hand, shown in Fig. 9 (b), along with batching, batching on the reel 10 by rolling stock 3, in the coiling diameter increase of the rolling stock 3 that batches reel 10 coilings.Accompany with it, the coiling Diameter Calculation value of 25 outputs also becomes big value from the coiling diameter calculating part 24 of control part 19 to extension and contraction control portion.In this case, also the big coiling diameter that calculates with coiling diameter calculating part 24 in extension and contraction control portion 25 cooperates and computing overcomes the power of the tension force of rolling stock 3, that is, intermediate calender rolls 13 is become from the pushing force (pushing force of intermediate calender rolls 13) of the position of the surface distance L of rolling stock 3.Based on this result, to extensible member 16 output instruction signals so that the pushing force of intermediate calender rolls 13 usefulness computings is pressed rolling stock 3.
Like this, even the coiling vary in diameter also can cooperate coiling diameter variation and intermediate calender rolls 13 is remained on from the non-contacting position of the surperficial set distance L of rolling stock 3.
Have, preferably, extension and contraction control portion 25 is designed to again, according to the pressing force of 3 pairs of rolling stocks 3 of deadweight correction intermediate calender rolls of intermediate calender rolls 13.That is, because intermediate calender rolls 13 and support unit 15 possess certain weight, so preferably, be in the posture that erects in the horizontal direction or towards the posture that vertical direction hangs down, increase and decrease pressing force according to support unit 15.
For example, support unit 15 than its pivot fulcrum 18 under the situation of batching reel 10 side oscillations, Fig. 9 (a) such begin to reel the time, the coiling diameter that is calculated by coiling diameter calculating part 24 is little, so the posture of support unit 15 for erecting from vertical direction to horizontal direction.Therefore, because of the deadweight of intermediate calender rolls 13, apply the power that is caused by the moment of conducting oneself with dignity to the direction opposite with the press direction of extensible member 16 on support unit 15,13 power that apply reduce from extensible member 16 to intermediate calender rolls.Given this, for the command signal of sending to extensible member 16, revise, make this pushing force increase the size of the power that above-mentioned moment produces.Export to extensible member 16 by revising the command signal (pushing force) that increases in extension and contraction control portion 25, the revised pushing force of extensible member 16 usefulness is pressed intermediate calender rolls 13 to batching reel 10 thrusters.
Shown in Fig. 9 (b), along with batching, batching on the reel 10 by rolling stock 3, and support unit 15 becomes the posture that hangs down from horizontal direction to vertical direction.And, cooperating the increase of coiling diameter, the coiling Diameter Calculation value from the coiling diameter calculating part 24 of control part 19 to 25 outputs of extension and contraction control portion also becomes big value, and the power that the moment by deadweight that applies to support unit 15 produces also diminishes.So, in extension and contraction control portion 25, reduce the correction of pressing signal to calculating according to tension force.
Like this, even intermediate calender rolls 13 is applied the formed power of moment of deadweight, also can make the power of extensible member 16 pushing intermediate calender rolls 13 increase and decrease the size of this power, so can leave the balance that the position of distance L obtains pushing force and tension force reliably on (coiling) surface that is wound on the rolling stock 3 that batches on the reel 10 certainly.
Have again, most preferably, under the situation that support unit 15 is swung to the opposition side that batches reel 10 than pivot fulcrum 18, also carry out the correction that above-mentioned deadweight causes.That is, support unit 15 than pivot fulcrum 18 under the situation of the opposition side swing of batching reel 10, the formed power of the moment of deadweight will with the identical direction effect of direction of pressing of extensible member 16.So, can deduct the power of correction from the command signal that extensible member 16 is applied.
The invention is not restricted to the respective embodiments described above, but the shape of each parts of appropriate change, structure, material, combination etc. in the scope that does not change invention essence.
For example, in the above-described embodiment, carry out the movement of intermediate calender rolls 13 according to coiling Diameter Calculation value, but for example also can be designed to following mechanism: the optical sensor of measuring the coiling diameter is set, according to the measured value of coiling diameter intermediate calender rolls 13 is moved.
In addition, can sensor be set at the front end of the support unit 15 that intermediate calender rolls 13 is installed, with extensible member 16 swinging mounting parts 15, so that be set scope by sensor measurement to the surperficial distance L of coiling.
Though in the above-described embodiment illustration roll mill 2 is used for the content of reversible rolling, intermediate calender rolls of the present invention mechanism 1 also can be used for adopting in the roll mill 2 of the milling method (for example, irreversible milling method) beyond the reversible rolling.
Though in the above-described embodiment, what intermediate calender rolls mechanism 1 was arranged on rolling device 2 batches side and unwinding side both sides, and intermediate calender rolls of the present invention mechanism 1 also can only arrange a side.
