The two ends of the metallic plate P throughput direction of the smoothing roll unit 20 between housing 1 and upper frame 2 dispose and depress cylinder body (pressing cylinder body) 4a and 4b, and this depresses cylinder body 4a and 4b gives respectively for the power of depressing (pressing force) of aligning metallic plate P. Depress cylinder body 4a and 4b and arrange two (with reference to Fig. 2 at the both ends of the width of metallic plate P respectively.Wherein, among Fig. 2 only diagram depress cylinder body 4a).
With respect to the lower smoothing roll 8 that is fixedly arranged at lower roll framework 10, depress cylinder body 4a and 4b and depress (that is, press and be pressed into) metallic plate P via top roll framework 5, top backing up roll 7 and upper straightening roll 6.In the situation that along A direction transferring metal plate P, depress cylinder body 4a and bring into play function as entering the depressing cylinder body of side, depress cylinder body 4b and bring into play function as going out the depressing cylinder body of side.And, in the situation that along B direction transferring metal plate P, depress cylinder body 4b and bring into play function as entering the depressing cylinder body of side, depress cylinder body 4a and bring into play function as going out the depressing cylinder body of side.And, also upper straightening roll 6 can be set regularly, utilization is depressed cylinder body and is depressed lower smoothing roll 8.
Each component parts of the roll leveller 100 of present embodiment is controlled by control device 30.As shown in Figure 3, control device 30 have process controller 31, the operating portion 32 inputted etc. and the storage part 33 of the needed information of stores processor.
Operating portion 32 and storage part 33 are connected in process controller 31.Operating portion 32 for example is made of the display of touch panel mode, and the needed information of input processing.Storage part 33 has the function that reads and write of the information of temporarily carrying out and stores the functions of control program that needs in order to carry out the various processing of being carried out by roll leveller 100.
In the control device 30, be set with the needed amount of being pressed into (drafts) of depressing cylinder body 4a and 4b of aligning (aligning) of metallic plate P according to thickness of metallic plate P etc.But, enter the depressing in the situation of the amount of being pressed into (the engaging-in limit amount of being pressed into) that the amount of being pressed into (the setting amount of being pressed into) that cylinder body (being in the situation of A direction for depressing cylinder body 4a at the throughput direction of metallic plate P) sets surpasses the engaging-in limit of metallic plate P of side, producing the engaging-in defective that metallic plate P does not have 8 of engaging-in upper straightening roll 6 and lower smoothing rolls.Therefore, in order to prevent so engaging-in defective, to control device 30(process controller 31) the engaging-in correction card of input shown in the example of Fig. 4.This engaging-in correction card is inputted at the touch panel of operating portion 32.And, also can input by reading the storage medium that the engaging-in correction card of Fig. 4 is stored.
In the engaging-in correction card of Fig. 4, divide and be set with the engaging-in limit amount of being pressed into δ L(mm according to each thickness of slab), engaging-in Correction and Control distance L b(mm) and depress erection rate IV(mm/sec).And, surpass in the situation of the engaging-in limit amount of being pressed into δ L in the setting value that enters the amount of being pressed into of depressing cylinder body of side (drafts), implement engaging-in Correction and Control with the engaging-in correction card of Fig. 4.Particularly, the front end of metallic plate P is begun from the summit of the benchmark smoothing roll (being the smoothing roll of left end in the situation that throughput direction is the A direction) that enters side engaging-in Lb distance during in the amount of being pressed into be controlled to be the engaging-in limit amount of being pressed into δ L, and after the benchmark smoothing roll that enters side begins the distance of engaging-in Lb, control with the erection rate IV that depresses that in engaging-in correction card, sets, be the setting amount of being pressed into so that enter the amount of being pressed into of depressing cylinder body (drafts) of side.The positional information of the metallic plate P of this moment can be obtained in the following way, namely, pass through a plurality of optical sensors (not shown) of position that line is provided for detecting the front end of metallic plate P along the smoothing roll unit in 20, after utilizing this optical sensor to detect the front end of metallic plate, use impulse generator (not shown) to follow the tracks of the front end of metallic plate P.
Next, the action when utilizing the roll leveller 100 that consists of like this to carry out the aligning of metallic plate P describes.
At first, metallic plate P is being directed under the state of guide roller 14 from the upstream side of the smoothing roll unit 20 of roll leveller 100, the 20 transferring metal plate P towards the smoothing roll unit, and insert it into 8 of upper straightening roll 6 and lower smoothing rolls.For example, be in the situation of A direction at the throughput direction of metallic plate P, the 20 transferring metal plate P from the left side of Fig. 1 to the smoothing roll unit are the cylinder body of depressing into side and depress cylinder body 4a.
At this moment, according to the thickness of metallic plate P etc., set the needed amount of being pressed into (drafts) of depressing cylinder body 4a and 4b of aligning (aligning) of metallic plate P at control device 30, carry out the aligning of metallic plate P with the amount of being pressed into after this setting (drafts).
But, the amount of being pressed into (drafts) after the setting of depressing cylinder body (being in the situation of A direction for depressing cylinder body 4a at the throughput direction of metallic plate P) that enters side surpasses in the situation of the engaging-in limit amount of being pressed into, and produces the engaging-in defective that metallic plate P does not have 8 of engaging-in upper straightening roll 6 and lower smoothing rolls.
Therefore, under these circumstances, carry out engaging-in Correction and Control based on the engaging-in correction card of Fig. 4, thereby prevent so engaging-in defective.In addition, in fact the engaging-in correction card of Fig. 4 charges to concrete numerical value.
Particularly, before 8 of the upper straightening roll 6 of the engaging-in smoothing roll of metallic plate P unit 20 and lower smoothing rolls, utilize the process controller 31 of control device 30, the engaging-in limit amount of the being pressed into δ L that divides to the setting amount of the being pressed into δ e1 that depresses cylinder body that enters side that sets according to conditions such as thicknesss of slab, with the thickness of slab corresponding to metallic plate P in the engaging-in correction card of Fig. 4 compares.And, in the situation that the setting amount of being pressed into δ e1 surpasses the engaging-in limit amount of being pressed into δ L, go to engaging-in modification model.
Namely, as shown in Figure 5, in the situation that the setting amount of being pressed into δ e1 surpasses the engaging-in limit amount of being pressed into δ L, the amount of being pressed into that enters the side pressure lower cylinder body of the reality during with engaging-in metallic plate P is restricted to the engaging-in limit amount of being pressed into δ L from the setting amount of being pressed into δ e1, the front end of metallic plate P begin from the summit of the benchmark smoothing roll (being the smoothing roll of #1 Fig. 5) that enters side the Lb that the correction card of engaging-in Fig. 4 sets distance during in, continue to carry out such quantitative limitation that is pressed into, as shown in Figure 6, after the benchmark smoothing roll that enters side began the distance of engaging-in Lb, the erection rate IV that depresses that sets with engaging-in correction card was adjusted into the amount of being pressed into of depressing cylinder body (drafts) that enters side and sets the amount of being pressed into δ e1 at the front end of metallic plate P.In addition, among Fig. 5, Fig. 6, with the most close benchmark smoothing roll that enters side be made as #1, for other smoothing roll, the numbering of giving #2 ~ #9 according to order from left to right.
Generally, in the engaging-in stage of metallic plate P, if the amount of being pressed into is the engaging-in limit amount of being pressed into δ L, then between the engaging-in up and down smoothing roll of metallic plate P, this engaging-in limit addition δ L is roughly proportional with the thickness of slab of metallic plate P.Thereby, if the length of the engaging-in regulation of metallic plate P even then the amount of being pressed into is larger than the engaging-in limit amount of being pressed into δ L, can not produce engaging-in defective yet.Therefore, thickness of slab according to metallic plate P is set the engaging-in limit amount of being pressed into δ L in advance in engaging-in correction card, and the length of afore mentioned rules is made as engaging-in Correction and Control distance L b, thereby can prevent reliably engaging-in defective, and can adjust to carry out the aligning of metallic plate P to the setting amount of being pressed into δ e1 rapidly, and then can keep the aligning yield rate of high metallic plate P.
And, depressing erection rate IV is to be formed into the speed of setting the amount of being pressed into δ e1 from the engaging-in limit amount of being pressed into, this depresses erection rate IV also is the value corresponding and suitable with the thickness of slab of metallic plate P, thereby depress erection rate IV by in correction card, setting in advance, can adjust to the setting amount of being pressed into δ e1 with the speed of optimum.
As mentioned above, according to present embodiment, in the engaging-in correction card, and the thickness of the metallic plate that should align is set with the amount of being pressed into of pressing cylinder body that enters side that is the engaging-in limit amount of being pressed into of the limit between the smoothing roll up and down of the engaging-in smoothing roll of metallic plate unit accordingly, and displacement that is the engaging-in Correction and Control distance that should be controlled to be the metallic plate front end of the engaging-in limit amount of being pressed into, to this engaging-in correction card of control device input, the needed setting of the aligning metallic plate amount of being pressed into of depressing cylinder body that enters side than the large situation of the engaging-in limit amount of being pressed under, control device is controlled based on engaging-in correction card, between engaging-in Correction and Control distance, the amount of being pressed into of depressing cylinder body that will enter side is restricted to the engaging-in limit amount of being pressed into, the front end of metallic plate arrive engaging-in Correction and Control apart from the time make the amount of being pressed into of depressing cylinder body into side become the amount of being pressed into of setting, thereby can prevent reliably engaging-in defective, and can carry out rapidly the aligning of metallic plate to the adjustment of the setting amount of being pressed into, and then can keep the aligning yield rate of high metallic plate.
Next, the second embodiment of the present invention is described.
For the roll leveller of present embodiment, essential structure is identical with the roll leveller 100 of the first embodiment, and only the mode of engaging-in Correction and Control is different from the first embodiment.
In above-mentioned the first embodiment, surpass in the situation of the engaging-in limit amount of being pressed into δ L at the setting amount of the being pressed into δ e1 that enters the side pressure lower cylinder body, the amount of being pressed into of carrying out entering the side pressure lower cylinder body is restricted to the engaging-in Correction and Control of the engaging-in limit amount of being pressed into δ L, after the summit of the benchmark smoothing roll that enters side began engaging-in Correction and Control distance L b, the amount of being pressed into that enters the side pressure lower cylinder body becomes set the amount of being pressed into δ e1 at the front end of metallic plate P.
But, in the first embodiment, for going out the side pressure lower cylinder body, do not carry out the control of the be pressed into amount corresponding with engaging-in Correction and Control.That is, in the first embodiment, the setting amount of the being pressed into δ d1 that goes out the side pressure lower cylinder body for the value of the corresponding warpage minimum of the setting amount of being pressed into δ e1 that enters the side pressure lower cylinder body.Therefore, in the engaging-in Correction and Control of the first embodiment, when the amount of being pressed into that enters the side pressure lower cylinder body is the engaging-in limit amount of being pressed into δ L, the situation that can't be made as the optimum amount of being pressed in going out the side pressure lower cylinder body is arranged.At this moment, as being in the situation of the hard and thin material such as high-tensile steel by the metallic plate P of aligning material, the situation that metallic plate P warpage in the engaging-in modification region (distance alpha when the engaging-in Correction and Control distance L b+ amount of being pressed into is changed to δ e1 from δ L) of having carried out engaging-in correction is arranged in metallic plate P as shown in Figure 7.If metallic plate P produces warpage like this, then in the situation that this warpage is lower warpage, as shown in Figure 8, because the distance that guide roller (work bench roller) is 14 is about 1m, so defectives such as the front end of generation metallic plate P and guide roller 14 butts, and in the situation that this warpage be on warpage, produce as illustrated in fig. 9 following defective, that is, with the both sides that are disposed at smoothing roll unit 20 and be used for pinch roll 14 butts make it easily to pass through by laminated metal sheet P or with auxiliary device (not shown) butt.
Therefore, in the present embodiment, as shown in figure 10, except divide to set the project identical with Fig. 4 according to each thickness of slab, divide ground to control device 30(process controller 31 according to each thickness of slab) input is set with correspondence and goes out side pressure and enter amount δ dE(mm) engaging-in correction card, this correspondence goes out side pressure and enters amount δ dE(mm) be to be the engaging-in limit amount of being pressed into δ L(mm with the amount of being pressed into that enters the side pressure lower cylinder body) time corresponding optimum the amount of being pressed into that goes out the side pressure lower cylinder body.Wherein, the optimum drafts that goes out side also exists with ... yield stress, thereby dividing to make according to steel grade is set with correspondence and goes out side pressure and enter amount δ dE(mm) correction card.And, surpass in the situation of the engaging-in limit amount of being pressed into δ L in the amount of being pressed into that enters the side pressure lower cylinder body (drafts) setting value, use the engaging-in correction card of Figure 10 corresponding with the steel grade division to implement engaging-in Correction and Control.
Particularly, as shown in figure 11, when the front end of metallic plate P begin from the summit of the benchmark smoothing roll that enters side engaging-in Lb distance during in engaging-in Correction and Control when carrying out, the amount of being pressed into that will enter the side pressure lower cylinder body is controlled to be the engaging-in limit amount of being pressed into δ L, and the amount of being pressed into that will go out the side pressure lower cylinder body is controlled to be to go out side pressure as the amount of being pressed into of the optimum corresponding with the engaging-in limit amount of being pressed into δ L corresponding and enter amount δ dE.And, after the engaging-in Correction and Control after the distance that begins engaging-in Lb from the benchmark smoothing roll that enters side finishes, control with the erection rate IV that depresses that sets in the engaging-in correction card, set the amount of being pressed into δ e1, δ d1 so that the amount of being pressed into (drafts) that enters the side pressure lower cylinder body and go out the side pressure lower cylinder body becomes.
Like this, when carrying out engaging-in Correction and Control, with corresponding by entering the engaging-in limit amount of the being pressed into δ L that the side pressure lower cylinder body carries out, the amount of being pressed into that will go out the side pressure lower cylinder body is controlled to be that correspondence goes out that side pressure enters amount δ dE and the amount of the being pressed into optimum of using the side pressure lower cylinder body, thereby can suppress the generation of the warpage of metallic plate P.
In addition, the present invention is not limited to above-mentioned embodiment, can carry out various distortion.For example, in the above-mentioned embodiment, represented to depress the situation that upper straightening roll is aligned the shape of metallic plate with depressing cylinder body, but also can depress the shape that lower smoothing roll is aligned metallic plate with depressing cylinder body.
