Description of the invention: The technical field to which the invention belongs to jt The present invention is related to a coil control method and apparatus thereof, and in particular, a method for performing coil coil control for a steel belt completed by Device. [Prior Art] In the hot milk manufacturing process, after the rolling of the roughing machine and the dryer, a steel strip of several hundred to several thousand meters is produced, in order to smoothly transport it to the lower line. To continue to strengthen, it is necessary to roll the finished steel strip into a cylindrical steel coil to facilitate transportation. - Refer to Fig. /, 2' - The method of processing 1 steel coil is to pass through one of the treatment systems 3 shown in Fig. 2 to smash the sputum, 兮老麻9... The treatment method 1 contains - high heat = pressed into a steel strip 21 pressing step u, cooling the steel strip ^ Γ = 3 and - cooling the steel strip " coiled into a coil of steel = this, 3 is provided with a nip unit 31 7 P drought 32, and - coil unit 33. Since the processing system 3 + steps 11 to 13, the t element is used to perform the functions of the above two steps 11 to 13 and the operation purpose and the various steps, respectively, the units 31 to The various implementation steps 11 to 13 that are known to ～13 are mainly explained, and the details are not described here. . The relative state of the Zhuo 70 31~33 is to match the functional limitations of the operator equipment, • the mountain test $ (for example, the type of steel embryo, the quality of the steel strip used, or the cost control, etc.), the whole 200902177 = sudden / money « under the premise of the situation, can extend a variety of solid samples. For example, the press-drying step n may be based on whether the steel preform 2 or the cold rolling operation is selectively heated, or alternatively, when the steel blank 2 is being rolled. In this case, you can also distinguish this operation in order: the two aspects of the program are carried out. The relevant details of the above-mentioned various procedures have been 丄: = the well-known art of the ordinary knowledge in the technical field, so there is no longer another here, in the coiling step, the use of the coil unit is to use a motor such as 34 The power-to-reel is called a coiling operation for the continuously conveyed flat steel strip 2, wherein the motor 331 is directed to the bending moment τΒ of the steel strip 2ι: bending, and the formula is as tr=^L··4 .. ......................(kg-mm) H(mm) and W(mm) are the thickness and width of the cross-sectional area of the steel strip, respectively (^ kgW ) is the ultimate stress required for the steel strip to produce bending plastic deformation, and the calculated Tb_ is the theoretical value corresponding to the target coil temperature of the steel strip. In the 1st processing method 1, it is generally estimated that the expected coiling stress of the steel strip 21 is to be subjected to bending plastic deformation at the expected coiling temperature, and the actual coiling temperature and the material of the steel strip 21 are greatly changed. The actual relief stress will inevitably have a considerable degree of error with the ideal state of the relief stress; compared to the motor 33 丨 赞 力矩 力矩 T T T T T T T T T T T T T T T T T T T T T T T T T T T T T Changes and changes in adjustment are obviously _ kinds of less suitable output power states. Therefore, in the coiling step 13, since the bending moment τ is too large or too small, the steel strip 21 is relatively easy to produce a condition in which the force and width control are poor. Therefore, the operator must strictly control the steel preform 20 at the stage of the coiling step 13 in order to finally obtain a steel coil of good quality; therefore, how to achieve the above objectives has become a problem for the relevant manufacturers. Efforts should be made to study the direction of development. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a coil control of a steel strip.

The higher the temperature, the lower the fall stress. On the contrary, the lower the temperature, the higher the stress is. See Figure 3 and 4, when the steel strip 50 passes through the After the rolling step 61 of the rolling unit 51, the cooling unit 52 is entered into the cooling unit 62, and then enters the coil control device 4, and the steps 72 to 74 of the driving, winding, and feedback are performed. In the driving step 72, the control unit 43 is used to provide a torque value of 200902177 to the power source 411, and the output torque value varies with different stresses, that is, The so-called output torque value of the Tingli is equivalent to the bending moment Tb of the power source 411 outputted by bending the steel strip 50, and the formula is compared with the bending of the output of the motor 331 in the previous dry & The torque 1 is the same as the following: ............ 4 ............................

接著進行該成捲步驟73 4Θ I .U 鄉73根據輸出力矩值之大小，該 動力源411就會提供對摩的 了應的動力，以驅使該捲軸412是以通 當的彎曲力矩TB轉動，蕤y_ 士 a 错此方式，便可以使該鋼帶50於該 捲軸412上形成盤捲狀態。Then, the winding step 73 is performed. The power source 411 provides the power to the motor to drive the reel 412 to rotate according to the bending moment TB. In this way, the steel strip 50 can be formed into a coiled state on the reel 412.
而由於各種鋼種經過壓軋步驟61與冷卻步驟62之後 ’其溫度狀況各有不同，倘若彎曲力矩ΤΒ都是維持固定值 而未隨實際溫度變動，在此種情況下，該動力源4ιι或是捲 軸412明顯是一種較不適合的輸出動力狀態。 為避免上述情況發生，本發明則進一步又執行該反饋 步驟74,利用該偵測單元42之偵溫器421測知鋼帶5〇溫 度，再透過該傳輸件422 ’送出鋼帶50溫度訊號，以供該 控制單7L 43之接收件432接收，來使得該控制單元43之 處理器433能夠依據該接收件432所接收的鋼帶％溫度， 而於該資料庫431中獲得相對應的降伏應力。 一方面，在本實施例中，是在該鋼帶5〇經過該冷卻步 11 200902177 驟62後且尚未進入該成捲步驟73前，進行測知鋼帶％溫 度，當然也可以是在該鋼帶5〇經過該成捲步驟73後才 進行測知鋼帶50溫度，本發明並不侷限於盤捲前或盤捲後（ 因為在這兩種狀況下的鋼帶5〇溫度並無太大差異），所以不 應以本實施例所揭露之範圍為限。 另一方面，由於該偵測單元42之偵溫器421是持續不 斷地測知鋼帶50溫度再送回該控制單元43處理運算，因 此11亥反饋步驟74結束後，還會回到該驅動步驟72與成 捲步驟73，用以供該控制單元43變動地提供該輸出力矩值 給該動力源41卜來驅使該捲軸412隨著實際盤捲溫度大小 ，以相對應的彎曲力矩轉動；此種驅動、成捲、反饋三步 驟72 74所構成的循環調控策略即稱為閉迴路控制。 因此，本發明鋼帶50之盤捲控制方法7及其裝置4， 具有下述之功效： (1) 即時控制鋼帶之盤捲張力與寬度達到良好品質： 由於本發明是利用該谓測單元42之偵溫5| 421測知鋼帶5〇溫度後，再根據該控制單元之 二貝料庫431得出實際盤捲溫度所對應的降伏應力 ，然後再藉由其處理器433之計算來變動提供該 輪出力矩值給該動力源411，以驅使該捲軸412是 以適當的、調變的彎曲力矩轉動，因此，可以使 得鋼帶50於該捲軸412上進行盤捲時，能夠即時 控制其張力與寬度而達到良好的盤捲產品品質 (2) 可滿足各種鋼種之盤捲需求： 12 200902177 由於每種鋼種的溫度一降伏應力曲線圖皆不 儘相同，因此，倘若操作人員只是依據經驗設定 輸出至捲軸412的彎曲力矩大小，一旦鋼種不同 ’报可能就會衍生盤捲力量過大或過小的狀況， 4成盤捲產品之張力或寬度品質欠佳；本發明則 是在該前置步驟71中，利用該控制單元43之資 料庫431内建設置多種鋼種的溫度一降伏應力曲 線圖除了可以避免人為經驗不足而導致彎曲力 矩設定錯誤之外，另外也可以依照各種不同鋼種 而於該資料庫431内選擇相對應的溫度—降伏應 力曲線圖，藉以滿足各種鋼種之盤捲需求。 (3)隨時修正可能發生的盤捲品質欠佳問題，提高盤 捲產品的產出效率： 於无刖技術中，要判斷盤捲後之鋼帶5〇張力 是否異常時，必需要將盤捲產品拿去檢測後才能 得知，然後才能依據檢測結果，調整輸出至捲軸 4!2的彎曲力矩大小，此種調整過程不僅相當費時 ，而且也會降低盤捲產品的品質與產出效率；反 觀本發明，毋需於事後進行檢測核判斷盤捲產 品的張力，只需於盤捲過程中即時測知盤捲溫度 就可決定輸出至㈣412的彎曲力矩大小，因此 本發明只需監控盤捲溫度的即時資訊，就可以 隨時二正可能發生的盤捲品質欠佳問題，並且也 月匕長馬盤捲產品的產出效率。 13 200902177 歸内上述，本發明鋼帶50之盤捲控制方法7及其裝置 4不僅可以即時控制鋼帶5〇之盤捲張力與寬度達到良好 品質，而且也能滿足各種鋼種之盤捲需求；再者，本發明 只需監控盤捲溫度的即時資訊，就可以隨時修正可能發生 的盤捲品質欠佳問冑’同時也能提高盤捲產品的產出效率 ’所以確實能夠達到本發明之目的。 惟以上所述者，僅為本發明之較佳實施例而已，當不 能以此限定本發明實施之範圍，即大凡依本發明申請：利 範圍及發明說明内容所作之簡單的等效變化與修飾，皆仍 屬本發明專利涵蓋之範圍内。 【圖式簡單說明】 圖1是一流程圖，說明一般鋼捲的處理方法； 圖2是一結構示意圖，說明一般鋼捲的處理系統； 圖3是-結構示意圖，說明本發明鋼帶之盤捲控制裝 置的較佳實施例； 圖4是一流程圖，說明本發明鋼帶之盤捲控制方法的 較佳實施例；及 圖5是-溫度-降伏應力曲線圖，說明M23:舰447 此鋼種之溫度一降伏應力特性。 14 200902177 ' 【主要元件符號說明】 4 盤捲控制裝置 50 鋼帶 41 盤捲單元 51 壓軋單元 411 動力源 52 冷卻單元 412 捲轴 61 壓軋步驟 42 偵測單元 62 冷卻步驟 421 偵溫器 7 盤捲控制方法 422 傳輸件 71 前置步驟 43 控制單元 72 驅動步驟 431 資料庫 73 成捲步驟 432 接收件 74 反饋步驟 433 處理器 15Since the various steel grades have different temperature conditions after the pultrusion step 61 and the cooling step 62, if the bending moment 维持 is maintained at a fixed value without changing with the actual temperature, in this case, the power source 4 ιι is either Reel 412 is clearly a less suitable output power state. In order to avoid the above situation, the present invention further performs the feedback step 74, using the temperature detector 421 of the detecting unit 42 to detect the temperature of the steel strip 5〇, and then sending the temperature signal of the steel strip 50 through the transmitting member 422'.

On the other hand, since the temperature detector 421 of the detecting unit 42 continuously detects the temperature of the steel strip 50 and sends it back to the control unit 43 for processing, after the 11th feedback step 74 is completed, the driving step is returned. And a winding step 73, wherein the control unit 43 variably provides the output torque value to the power source 41 to drive the reel 412 to rotate with a corresponding bending moment according to the actual coil temperature; The loop control strategy consisting of three steps 72 74 of driving, rolling, and feedback is called closed loop control. Therefore, the coil control method 7 and the apparatus 4 thereof of the steel strip 50 of the present invention have the following effects: (1) Instantly controlling the coil tension and width of the steel strip to achieve good quality: Since the present invention utilizes the pre-test unit 42 Detecting temperature 5| 421 After measuring the temperature of the steel strip 5 〇, the undulation stress corresponding to the actual coiling temperature is obtained according to the second hopper 431 of the control unit, and then calculated by the processor 433 thereof. The variation provides the wheel torque value to the power source 411 to drive the spool 412 to rotate with an appropriate, modulated bending moment, thereby enabling immediate control of the steel strip 50 when coiled on the spool 412. Its tension and width to achieve good coil quality (2) can meet the coil demand of various steel types: 12 200902177 Because the temperature-equivalent stress curve of each steel type is different, therefore, if the operator is only based on experience Set the bending torque output to the reel 412. Once the steel type is different, it may result in the condition that the coiling force is too large or too small, and the tension or width quality of the 4 coiled product is not good; In the pre-step 71, the temperature-floating stress curve of the plurality of steel types built in the database 431 of the control unit 43 can be used to avoid the setting of bending moments due to insufficient human experience, and can also be A variety of different steel grades are selected in the database 431 to select a corresponding temperature-equivalent stress curve diagram to meet the coiling requirements of various steel grades. (3) Correct the problem of poor quality of coils that may occur at any time, and improve the output efficiency of coiled products: In the flawless technology, if it is necessary to judge whether the tension of the steel strip after coiling is abnormal, it must be coiled. After the product is tested, it can be known, and then the bending torque output to the reel 4!2 can be adjusted according to the detection result. This adjustment process is not only time-consuming, but also reduces the quality and output efficiency of the coil product; According to the present invention, it is not necessary to carry out the test core to determine the tension of the coil product afterwards, and it is only necessary to measure the coil temperature in the coiling process to determine the bending moment of the output to (4) 412. Therefore, the present invention only needs to monitor the coil temperature. The real-time information, you can always have the problem of poor quality of the coils that may occur at any time, and also the output efficiency of the long-term coil products. 13 200902177 In the above, the coil control method 7 and the device 4 of the steel strip 50 of the present invention can not only control the coil tension and width of the steel strip 5〇 to achieve good quality, but also meet the coiling requirements of various steel types; Furthermore, the present invention only needs to monitor the instantaneous information of the coil temperature, and can correct the possible poor quality of the coil at any time, and at the same time improve the output efficiency of the coiled product, so it is indeed possible to achieve the object of the present invention. . However, the above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the present invention in the scope of the invention and the description of the invention. All remain within the scope of the invention patent.
