Description of the Invention: [Technical Field of the Invention] The present invention relates to a rolling control device and a rolling control method device. [Prior Art] The calendering technique is to form a material which is repeatedly formed into a specific thickness by a work roll. The manufacturer desires to uniformly form the calendered material in the direction of the sheet width, but it causes a so-called edge reduction phenomenon in which the sheet thickness at the end of the sheet is reduced. In order to suppress this, the so-called work drum displacement is performed as follows, that is, the work rolls which are respectively moved in a table shape and have a taper in the axial direction. Such a technique is disclosed, for example, in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. In this case, since the operation side and the drive side become asymmetrical, the rolled material is bent or the plate is broken. Therefore, when the difference in the moving position of the upper and lower work rolls is large, the movement operation is restricted. In the prior art, the difference in the vertical movement position is used to limit the private movement of the work drum, so that it cannot sufficiently correspond to the calendering. It is difficult to accurately set the limit value by the rolling progress of the material or the shape of the work roll. Moreover, the asymmetry between the operation side and the drive side fluctuates due to the state of the material to be rolled, so that, for example, the plate thickness on the kneading side is larger than that on the drive side. When the rolling pressure on the operating side is soared, the reduction ratio of the side of the fine side (the value of the difference between the thickness of the inlet side plate and the side of the side plate 10253l-950622.doc 1262829) will change. Generally, it is inconsistent with the prior art. Therefore, it is inevitable that the plate bending cannot sufficiently control the wide end of the plate or the plate is broken. The plate width direction plate of the wide end portion of the plate width direction of the plate is the object of high precision. In order to achieve the above object, the present invention is configured to control the thickness distribution in the plate width direction of the end portion in the thickness direction, calculate the amount of movement of the work roll, and based on the rolling state on the operation side and the driving side. The rolling state restricts the movement of the drum =. According to the present invention, the rolling control for obtaining the plate thickness distribution in the plate width direction at the end portion of the plate with high precision can be realized. [Embodiment] The best practice of the present invention will be described using the drawings. Fig. 2 (Α) shows that the work rolls 14 1 and 142 form the rolled material 2. The upper work roll 丨 4 丨 (hereinafter, the work roll is also referred to as a work roll or simply WR) Hereinafter, it is also referred to as oblique processing. The side of the inclined processing is referred to as an inclined side.) As the operation side (abbreviated as the WS side), the lower work cylinder 142 is referred to as a driving side (referred to as a DS side). By providing the processed portions of the work rolls 14 1 and # 2 in this manner, the shape of the plate end portion of the rolled material 2 can be independently controlled on the operation side (WS side) and the drive side (DS side). 1 and 1 42 are subjected to tip finishing, so that the distribution of the rolling force applied to the rolled material 2 can be changed by changing the position of the work rolls 14 1 and 142 in the plate width direction. For example, the circle pc of Fig. 2(A) As shown therein, the starting point of the tip finishing is set to be inside the plate width of the calendering material 2, and the rolling force applied to the end of the plate of the calendering material 2 10253I-950622.doc 1262829 can be reduced. The plate width at the end of the plate is distributed in the thickness direction. The control of the plate thickness distribution in the plate width direction of the end portion of the plate is referred to as edge reduction control. Therefore, the control is hereinafter referred to as edge reduction control. The edge reduction control device 丨 23 is shown in FIG. The edge reduction control device has a function of controlling the work rolls 141 and 142 (shown in Fig. 2). First, an outline of the edge reduction control in the edge reduction control means 123 will be briefly explained. In general, a four-stage calender structure including a work roll shown in FIG. 2 and a support roll (also referred to as BUR) (not shown) or an intermediate roll (abbreviated as IMR) is further added. 26-stage calender construction. Next, the details of the edge reduction control of the edge reduction control means 123 will be described. The present invention uses the edge reduction detection value detected by the ingress side edge lowering detector ι〇ι and the out side edge lowering detector 102 to perform edge reduction control, the ingress side edge lowering detector 1〇1 and the out side edge lowering detection The device 1〇2 is set to ns (n is a number greater than 2, and in Fig. 1+, "Taiwan, #2台104,···##1〇8.) is arranged. The tandem calender. Specifically, The entry side edge lowering detector 101 and the exit side edge lowering detector 1〇2 are formed by arranging a plurality of detectors in the width direction of the rolling material 2 (the rolled material 2), as shown in FIG. 2(B). By detecting the thickness distribution of the calendered material (calendered material), the output is offset from the target value. The edge reduction control can be used to reduce the feedback of the detector 丨〇2 using the exit edge, or to reduce the edge of the input side. The detector 101 feeds forward control, that is, feedback control, which detects the plate thickness distribution of the plate end portion (difference from the target plate thickness distribution), and performs plate thickness distribution identification of the plate end portion. , its knot 102531-950622.doc 1262829 The plate thickness distribution determines the displacement direction of the work roll displacement (丨4^) according to the result. Fig. 2(B) shows the plate thickness distribution in the edge reduction control and the plate thickness distribution in the plate width direction of the plate end ( The FB (feedback) control signal calculated based on the difference between the detected values). The out-side edge reduction detecting person 102 identifies and detects the edge reduction deviation of the operation side (ws side) and the driving side (DS side), respectively, and performs calendering The operation side (~8 side) and the drive side (ds side) of the machine are independently controlled. As a result, the work on the lower side of the plate end thickness is changed outward from the displacement position, and the end of the plate is changed. The displacement position of the work roll on the upper side of the plate thickness is changed inward, and the operation side (WS side) and the drive side (DS side) are independently controlled by such operation. Thus, in the edge reduction control device 123, the self-edge reduction detection value calculation #1 The correction amount of the displacement position in the axial direction of the upper and lower rollers 141 and 142 in the table 103 and the #2 table 104."#11 table 108. The displacement of the work drum is controlled according to the displacement position correction amount of the upper and lower work rolls 141 and 142. The position 122 will adjust the displacement position of the upper and lower work rolls. In the calender, a load meter 109 as a mechanism for detecting a rolling load, and a tension meter 1〇6, 107 as a mechanism for detecting the tension between the rolling stands are provided. The load gauges 1〇8 and 109 and the tensiometers 1〇6 and 1〇7 can detect the load difference 110, 114 and the tension difference 112 which are the difference between the operation side (WS side) and the drive side (DS side) of the calender. 116. In the calender, for example, when the load on the driving side (DS side) is higher than the operation side (WS side), the driving side (1) § side) is further subjected to the pressing state, so the self-calender per unit time The length of the sheet of the rolled material 2 sent out to the exit side will be larger than that of the operation side (ws side). Therefore, the tension applied to the rolled material 2 becomes higher on the operation side (ws side). 102531-950622.doc 1262829 Subsequently, it is provided that the drum can be positioned to block the stagnation device 120 to limit the displacement operation, and the judging device 120 detects the load difference (1) 〇, m) or the tension difference (1) 2, 116)' It is judged that the asymmetry of the extension machine, when it is greater than the level of asymmetry, will stop the displacement of the upper and lower work rolls ((4), (4)) in the direction in which the asymmetry becomes larger. The details of the drum displacement determining means 12 are shown in Fig. 3 (4). Here, the movement of the upper and lower work rolls _ is restricted by the use of the # load difference of the dust elevator and the command of the drum displacement control I22 is limited. When the load meter (10) and (10) on the drive side (DS side) are more than 0·1 times the squat load, it is determined that the drive side (DS side) is large, and the upper and lower work rolls can be pushed by the limit displacement operation (10). , 142) is limited in the direction of displacement. = Fig. 3(B) shows the reasoning used in the limit displacement motion inference engine 3〇1. In the drum displacement control device 122, = is off. Based on the output, it is limited in the private direction of the upper and lower work rolls ((4), ).胄 @ ^ Inference rules in the object... and § ‘will prohibit 图 ) as in ", for the combination of the displacement operation of the lower roller. In the case of the first example, the upper working cylinder (14 is obtained by the door (41) from the private side to the driving side. (4) 'the lower working cylinder is controlled by moving to the operating side, even if the load is poorly set. (4), and 'even if the load difference' is set value (〇·〗), the control 吏 load difference = production is expected to be i i L and the 忒 control can be continued. Example 2 is the upper work roller (141) to move to drive The side mode is controlled by 102531-950622.doc 1262829 and the lower working roller (142) is controlled to move to the driving side. This % 'If the load difference is the set value (01), the control is limited = 10 (10) And (4)) displacement. On the other hand, if the U setting value (〇·" is used, the control can be allowed' and the control can be continued. The same is true for the examples 3 to 8. Even if the driving side (DS side) is used as the tension between the stages. And the tension difference (1) 2, 116) of the difference between the side and the side of the operation side can also be used to determine the drum displacement determination device in the same manner as the load difference (1) 〇, and the same, even if the load difference (1) 〇, 114) and the tension difference are used. In the case of the load difference 〇1, 114), the drum displacement determining device 12 may be configured in the same manner as in the case of the load difference 〇1, 116). There are inference rules to determine whether the drum can be displaced, but other methods can be used for judgment. In addition, the bending amount can also be measured and used using the bending sensor, which can be used as the operating side (ws side) and the driving side. (10) The difference between the extended state of the side), for example, as the width direction of the rolled material 2 + the position of the central position and the center of the calender, or the position sensor can be used to measure and use the difference between the roller gaps In the above embodiment, although the edge reduction control with the displacement of the work rolls has been described, the edge reduction control using the intermediate roll displacement can be constructed in the same manner. As described above, the drive side of the calender can be used. The difference in the rolling state on the operating side limits the displacement operation of the upper and lower rollers. Therefore, the edge reduction control can be performed by maximally utilizing the displacement of the upper and lower rollers, and the rolling progress or the width distribution of the side plate thickness is not affected. Therefore, the occurrence of plate bending 102531-950622.doc •10-1262829 bending or plate breakage can be minimized [simple description of the drawing] and the control precision is improved.
