發明領域
本發明是有關於一種在連結配管、閥、泵浦等之凸緣鎖緊上使用的密封施工的管理技術。FIELD OF THE INVENTION The present invention relates to a management technique for sealing construction used for flange locking of connecting pipes, valves, pumps, and the like.

發明背景
在配管連結或泵浦等對配管的連接中，會利用已將墊片夾入的凸緣。此凸緣是在設定於周緣側之複數處的鎖緊處上，藉由螺栓與螺帽的鎖緊來緊固。螺栓與螺帽的鎖緊會使用扭矩扳手等之手動的鎖緊工具、或電動式的螺絲鎖緊工具等。
在像這種螺栓及螺帽對凸緣的鎖緊中，是在全部的鎖緊處中以規定的扭矩值來進行鎖緊處理，且必須使作用於螺栓的軸力不產生偏差來進行鎖緊。因此，由鎖緊工具所進行之螺栓及螺帽的鎖緊狀態的管理會變得重要。BACKGROUND OF THE INVENTION In piping connection, pump connection, and the like, a flange having a gasket sandwiched therebetween is used. This flange is fastened by the locking of the bolt and the nut at the locking places set at a plurality of positions on the peripheral side. The bolts and nuts are tightened using a manual tightening tool such as a torque wrench or an electric screw tightening tool.
In this kind of bolt and nut-to-flange locking, the locking process is performed at a predetermined torque value in all the locked places, and the axial force acting on the bolt must be locked without deviation. tight. Therefore, the management of the locked state of the bolt and the nut by the locking tool becomes important.

在鎖緊管理方法中，例如有：管理施加於螺栓的鎖緊扭矩之扭矩法、以超音波軸力計來測定螺栓的延伸以管理軸力的方法、將螺栓拉伸至設為目標的軸力，使螺帽就位而進行鎖緊，藉此一邊管理軸力一邊進行螺栓的鎖緊之螺栓拉緊器(bolt tensioner)(拉伸法)等之方法。Examples of the tightening management method include a torque method that manages the tightening torque applied to the bolt, a method that measures the extension of the bolt with an ultrasonic axiometer to manage the axial force, and that the bolt is stretched to the target axis A method such as a bolt tensioner (tensile method) in which the nut is locked in place by tightening the nut while tightening the bolt while managing the axial force.

有關於像這種凸緣的鎖緊管理，已知有下述方式：藉由檢測器來電性檢測出螺栓的輸出軸的旋轉速度或扭矩，並且將此檢測值分解成針對鎖緊經過時間之每一刻的旋轉速度與扭矩值，來算出每個微小時間的動力值，或因應於鎖緊變動負荷的狀態來對動力扳手的旋轉速度當量瞬間地作增減控制，藉此使每個微小時間的輸出軸動力近似於輸出扭矩(例如，專利文獻1)。又，已知有利用關係式來算出預測軸力的方式(例如，專利文獻2)，前述關係式是將螺合構件的鎖緊完成時的軸力與從完成時經過規定時間後的軸力之比作為鎖緊所需要的時間之函數來表示。已知一種具備鎖緊凸緣之螺栓的軸力檢測感測器，在螺栓的軸力比設定值更小的情況下，使鎖緊動作執行之方式(例如，專利文獻3)。
先前技術文獻
專利文獻Regarding the locking management of such a flange, the following methods are known: the rotation speed or torque of the output shaft of the bolt is detected by the electricity of the detector, and this detection value is decomposed into The rotation speed and torque value at each moment can be used to calculate the power value at each minute time, or the rotation speed equivalent of the power wrench can be increased or decreased instantaneously according to the state of the locked variable load, thereby making each minute time The output shaft power is approximately the output torque (for example, Patent Document 1). Further, a method is known in which a predicted axial force is calculated using a relational expression (for example, Patent Document 2). The relational expression is an axial force at the completion of locking of the screwed member and an axial force after a predetermined time has elapsed from completion. The ratio is expressed as a function of the time required for locking. An axial force detection sensor for a bolt provided with a locking flange is known to perform a locking operation when the axial force of the bolt is smaller than a set value (for example, Patent Document 3).

發明概要
發明欲解決之課題
然而，將墊片夾入的凸緣連接，必須將全部的螺栓及螺帽的鎖緊軸力均等化，藉此使凸緣彼此維持成平行。在將複數個螺栓及螺帽鎖緊的凸緣連接中，若作用於螺栓的軸力產生偏差，則會在凸緣間產生傾斜。成為所謂不均勻鎖緊之狀態。在像這種不均勻鎖緊之狀態下，會有導致在藉由凸緣連結的管路中產生間隙、或是由凸緣間的墊片所產生之密封功能降低等之課題。
又，由扭矩法所進行之鎖緊管理雖然是管理以螺栓及螺帽的鎖緊所賦與的鎖緊扭矩，但是鎖緊扭矩與作用於螺栓的軸力之比例係數即扭矩係數會受到針對凸緣或螺帽的摩擦等的影響，使每個螺栓的軸力有偏差。因此，即使以根據鎖緊時必要的鎖緊力所算出的鎖緊扭矩來進行鎖緊，仍然會有因扭矩係數的差異而在凸緣的每個鎖緊位置上產生作用於螺栓的軸力偏差之課題。SUMMARY OF THE INVENTION Problems to be Solved by the Invention However, to connect flanges sandwiched by shims, it is necessary to equalize the locking axial forces of all bolts and nuts to maintain the flanges parallel to each other. In a flange connection in which a plurality of bolts and nuts are locked, if the axial force acting on the bolts is deviated, a tilt occurs between the flanges. It is in a state of so-called uneven locking. In such a non-uniformly locked state, there are problems such that a gap is generated in a pipe connected by flanges, or a sealing function is reduced due to a gasket between flanges.
In addition, although the tightening management by the torque method manages the tightening torque provided by the tightening of bolts and nuts, the torque coefficient, which is the proportional coefficient of the tightening torque and the axial force acting on the bolt, is targeted The influence of the friction of the flange or the nut, etc., makes the axial force of each bolt deviate. Therefore, even if locking is performed with a locking torque calculated from the necessary locking force at the time of locking, there will still be an axial force acting on the bolt at each locking position of the flange due to the difference in torque coefficient. The subject of deviation.

在利用超音波軸力計的鎖緊管理中，是在進行了螺栓的鎖緊後測定軸力，且會為了將軸力均一化而進行再上緊或重新上緊，因此會有導致作業工時或作業時間的增加之課題。在螺栓對凸緣的鎖緊作業中，是針對1個螺栓一邊改變鎖緊扭矩的值一邊進行複數次鎖緊，因此若要將鎖緊扭矩值調整成每次都成為目標軸力，則作業時數會變得龐大。又，由於螺栓的再上緊或重新上緊會因彈性相互作用的影響，而受到其他螺栓的鎖緊發生鬆動等之影響，因此鎖緊後的軸力調整會導致作業負荷的增加。
在由螺栓拉緊器所進行之鎖緊管理中，會有必須有專用的工具而耗費費用或作業時間，或是為了拉伸螺栓而必須有螺栓的額外長度之課題。此外，以油壓來對螺栓施予軸力，並且使螺帽就位於螺栓等之被緊固體，再去除油壓即可完成鎖緊，但是在去除油壓時，螺帽支承面會變形成沉入被緊固體表面，而低於油壓所施予的軸力。為了彌補要這點，雖然可將初始軸力設定成較高，但是在緊固體的強度不足的情況下，也會有產生破損的危險、或是難以推定降低的軸力之課題。In the tightening management using an ultrasonic axonometer, the axial force is measured after the bolts are tightened, and re-tightening or re-tightening is performed in order to uniformize the axial force. Increase in hours or working hours. In the bolt-to-flange tightening operation, multiple bolts are locked while changing the value of the tightening torque for one bolt. Therefore, if the value of the tightening torque is adjusted to become the target axial force each time, the operation is performed. Hours can grow huge. In addition, the re-tightening or re-tightening of the bolt is affected by the elastic interaction, and is affected by the loosening of the locking of other bolts. Therefore, the adjustment of the axial force after the locking causes an increase in the working load.
In the tightening management by the bolt tensioner, there are problems that a dedicated tool is required to consume costs or working time, or that extra length of the bolt is necessary in order to stretch the bolt. In addition, oil pressure is used to apply axial force to the bolt, and the nut is located on the fastened body such as the bolt, and then the oil pressure can be removed to complete the locking. However, when the oil pressure is removed, the nut supporting surface will change. It sinks into the surface of the fastened body and is lower than the axial force given by the oil pressure. In order to compensate for this, although the initial axial force may be set to be high, when the strength of the fastening body is insufficient, there is a risk of breakage or difficulty in estimating a reduced axial force.

在已夾入有墊片的凸緣之密封施工中，雖然是採用像這種鎖緊管理之任一者，來進行由設定於鎖緊工具的扭矩值所進行之鎖緊或鎖緊後的調整等，但是為了使已鎖緊的螺栓的軸力均一化，需要大量的時間或作業勞力或成本。本申請的發明者是根據由這些鎖緊管理的手法所造成之軸力的偏差會受每個螺栓的狀態的差異影響之知識見解，將調整可利用於算出鎖緊扭矩值的扭矩係數來進行鎖緊管理這點作為發明的課題。
針對這樣的課題，在專利文獻1~3中並無揭示也無提示，且這些文獻所揭示的構成並無法解決這樣的課題。In the sealing construction of the flange with the gasket sandwiched, although any of such locking management is adopted, the locking or locking by the torque value set in the locking tool is performed. Adjustment, etc. However, in order to make the axial force of the bolts that have been locked uniform, it takes a lot of time, labor, or cost. The inventor of the present application is based on the knowledge that the deviation of the axial force caused by these locking management methods is affected by the difference in the state of each bolt, and adjusts the torque coefficient that can be used to calculate the locking torque value. The point of lock management is the subject of the invention.
Regarding such problems, there is no disclosure or suggestion in Patent Documents 1 to 3, and the structures disclosed in these documents cannot solve such problems.

於是，本發明之目的在於：有鑒於上述課題，能以較少的作業工時及作業時間來進行螺栓及螺帽的鎖緊，並且實現鎖緊精確度高的凸緣連接。
又，本發明之其他目的在於：施加與每個螺栓及螺帽的狀態相因應的鎖緊扭矩，藉此實現針對凸緣的鎖緊狀態的安穩定化及必要的軸力下的鎖緊。
這樣的課題的揭示或提示並不存在，且專利文獻1至專利文獻3所揭示的構成並無法解決這樣的課題。
用以解決課題之手段Therefore, an object of the present invention is to achieve the above-mentioned problem, and it is possible to lock bolts and nuts with a small number of man-hours and working hours, and to realize a flange connection with high locking accuracy.

e.利用已算出的補正扭矩係數k2，來算出或選定已補正的鎖緊扭矩值T2之功能。> Function of Control Module 16>
The control module 16 provided with the sealed construction management device 2 having such a configuration has the following functions, for example.
a. Calculate or select the function of the tightening torque value T1 assigned to the bolt 6 or the nut 8 according to the set torque coefficient k1 and the number of tour S of the tightening place.
b. Set the locking torque value T1 to the function of the locking tool 14.
c. The function of changing the locking torque value T1 of the locking tool 14 in stages or continuously according to the number of tours S (STEP). This number of rounds S is the unit of the positions of P1, P2,..., Pn, which are the locking positions of the bypass bolt 6 and the nut 8.
d. Obtain the detection result of the axial force acting on the bolt 6 or the nut 8 by locking to calculate the function of correcting the torque coefficient k2 corresponding to the locking point P.
e. The function of calculating or selecting the corrected locking torque value T2 by using the calculated correction torque coefficient k2.

功能a的鎖緊扭矩值T1是利用例如目標軸力的值來算出的鎖緊扭矩值。此鎖緊扭矩值T1是作為等級值(level value)而被算出，前述等級值是根據包含墊片12的鎖緊條件來到達設為目標的軸力F時所需之值。在鎖緊扭矩值T的算出中，是利用以下的數式。
T＝kFd/n　　　　　　　　　　　　　　　…(1)
在此，d是要鎖緊的螺栓6的外徑，n是設置於密封施工部4的螺栓6或螺帽8的數量。又，k是表示鎖緊扭矩T與鎖緊力(軸力F)的比例係數之扭矩係數。
例如圖2所示，螺栓6及螺帽8的軸力F是相對於從鎖緊工具14所施加的鎖緊扭矩T，而受到凸緣10-1或10-2與螺栓6或螺帽8的支承面的摩擦力N1、螺紋面的摩擦力N2等之影響。又，此鎖緊的軸力F是受到螺紋的表面粗糙度等之影響。亦即，根據鎖緊處的不同，即使以相同的鎖緊扭矩值T1來鎖緊，作用於螺栓6及螺帽8的軸力F仍會有所不同。考慮到像這種影響而設定的扭矩係數k是因應於每個螺栓6或螺帽8的鎖緊處P而成為不同的值。在密封施工開始時的鎖緊扭矩值T1的算出中，是將例如針對全部的鎖緊處P的扭矩係數k1作為一定的值而設定為0.2。The locking torque value T1 of the function a is a locking torque value calculated using, for example, a value of a target axial force. This locking torque value T1 is calculated as a level value, which is a value required when reaching the target axial force F based on the locking condition including the shim 12. In the calculation of the tightening torque value T, the following formula is used.
T = kFd / n… (1)
Here, d is the outer diameter of the bolt 6 to be tightened, and n is the number of bolts 6 or nuts 8 provided in the seal construction portion 4. In addition, k is a torque coefficient indicating a proportionality coefficient of the locking torque T and the locking force (axial force F).
For example, as shown in FIG. 2, the axial force F of the bolt 6 and the nut 8 is subjected to the flange 10-1 or 10-2 and the bolt 6 or the nut 8 with respect to the locking torque T applied from the locking tool 14. The frictional force N1 of the bearing surface, the frictional force N2 of the thread surface, and the like. The locking axial force F is affected by the surface roughness of the screw and the like. That is, depending on the locking position, the axial force F acting on the bolt 6 and the nut 8 may be different even if the locking is performed with the same locking torque value T1. The torque coefficient k set in consideration of such an influence is a different value depending on the locking point P of each bolt 6 or the nut 8. In the calculation of the tightening torque value T1 at the start of the sealing construction, for example, the torque coefficient k1 for all the lock points P is set to a fixed value of 0.2.

在功能b中，已算出的扭矩值T1會被設定於鎖緊工具14，來作為由控制組件16針對鎖緊工具14的控制資訊。In function b, the calculated torque value T1 is set in the locking tool 14 as control information for the locking tool 14 by the control unit 16.

在功能c中，控制組件16是因應於鎖緊巡迴次數S，來使由鎖緊工具14所產生的鎖緊扭矩值T1分階段地或連續地變更，以進行鎖緊。藉此，使各鎖緊處P的螺栓6或螺帽8的軸力到達目標軸力F。In function c, the control unit 16 changes the locking torque value T1 generated by the locking tool 14 in stages or continuously in response to the number of locking cycles S to perform locking. Thereby, the axial force of the bolt 6 or the nut 8 of each locking place P is made to reach the target axial force F.

在功能d中，控制組件16是取得從與例如鎖緊處P相對應的軸力感測器18-1、18-2、…、18-n檢測到的軸力F。檢測到的軸力F可在每次進行了鎖緊時取得，或亦可在進行了規定的巡迴次數S的鎖緊時取得。並且，控制組件16是利用例如數式(1)，來算出每個螺栓6或螺帽8的補正扭矩係數k2。在補正扭矩係數k2的算出中，是利用設定好的扭矩值T1與檢測到的軸力F。In the function d, the control unit 16 obtains the axial force F detected from the axial force sensors 18-1, 18-2,..., 18-n corresponding to, for example, the locking point P. The detected axial force F may be obtained each time the locking is performed, or may be obtained when the locking is performed a predetermined number of rounds S. The control unit 16 calculates a correction torque coefficient k2 for each bolt 6 or nut 8 using, for example, Equation (1). In the calculation of the correction torque coefficient k2, the set torque value T1 and the detected axial force F are used.

在功能e中，控制組件16是利用補正扭矩係數k2與目標軸力，根據數式(1)來算出已補正的鎖緊扭矩值T2，並設定於鎖緊工具14。In the function e, the control unit 16 calculates the corrected locking torque value T2 based on the formula (1) using the corrected torque coefficient k2 and the target axial force, and sets the corrected locking torque value T2 in the locking tool 14.

>密封施工管理的結果>
圖3是顯示鎖緊步驟中的檢測軸力之一例。
控制組件16是管理例如在鎖緊處P檢測到的軸力，並且藉由未圖示的顯示組件，對進行鎖緊的作業人員或作業管理者通知管理結果。
圖3之A是例如將扭矩係數設定為一定的值k1＝0.2而進行了鎖緊的情況之軸力檢測結果之一例。此鎖緊結果Fα中，例如鎖緊處[1]~[5]、[8]的檢測軸力會成為同等的值，相對於此，鎖緊處[7]中的鎖緊結果Fα1的值會變小，又，鎖緊處[6]中的鎖緊結果Fα2的值會成為比其他鎖緊處更大的值。亦即，即使以相同的鎖緊扭矩值T1來進行鎖緊，也明確可知對於鎖緊處[7]與[6]的狀態，扭矩係數k1並不是適當的值。
又，圖3之B是設定與每個鎖緊處相對應的補正扭矩係數k2而進行了鎖緊的情況之軸力檢測結果之一例。在此鎖緊結果Fβ中，鎖緊處[7]、[6]的鎖緊結果Fβ1、Fβ2的值是和其他鎖緊處的檢測軸力的值成為同等。藉此即可抑制作用於凸緣10-1、10-2的整體之軸力的偏差。> Results of Sealed Construction Management>
FIG. 3 shows an example of the detected axial force in the locking step.
The control unit 16 manages, for example, the axial force detected at the locking point P, and notifies the operator or the operation manager of the locking result by a display unit (not shown).
FIG. 3A is an example of an axial force detection result when the torque coefficient is set to a constant value k1 = 0.2 and locked. In this locking result Fα, for example, the detected axial forces at the locking points [1] ~ [5], [8] will become equal values. In contrast, the value of the locking result Fα1 at the locking points [7] Will become smaller, and the value of the locking result Fα2 in the locking place [6] will become larger than other locking places. That is, even if the locking is performed with the same locking torque value T1, it is clear that the torque coefficient k1 is not an appropriate value for the states of the locking places [7] and [6].
In addition, FIG. 3B is an example of an axial force detection result when a correction torque coefficient k2 corresponding to each locking place is set and locked. In this locking result Fβ, the values of the locking results Fβ1 and Fβ2 at the locking positions [7] and [6] are equal to the values of the detected axial force at other locking positions. This can suppress variations in the axial force acting on the flanges 10-1 and 10-2 as a whole.

>密封施工管理處理>
圖4是顯示密封施工管理處理例。圖4所示的處理順序、處理內容只是本發明的密封施工管理方法或密封施工管理程式之一例，本發明並不限定於這樣的內容。> Sealing Construction Management Processing>
Fig. 4 shows an example of a sealing construction management process. The processing sequence and processing content shown in FIG. 4 are only examples of the sealed construction management method or the sealed construction management program of the present invention, and the present invention is not limited to such contents.

在密封施工管理處理方面，控制組件16會利用目標軸力或設定軸力與第1扭矩係數k1，來進行第1鎖緊扭矩值T1的算出或選定(S1)，並且將此第1鎖緊扭矩值T1設定於鎖緊工具14(S2)。目標軸力是在鎖緊完成時作用於螺栓6或螺帽8的軸力F之目標值。在因應於巡迴次數S而使針對螺栓6及螺帽8的鎖緊扭矩值T1分階段地變化的情況下，設定軸力會是在算出鎖緊扭矩值T1時所設定之軸力F的值，可因應於例如巡迴次數S來設定為目標軸力的x[%]等。又，鎖緊扭矩值T1亦可選定例如事先儲存於資料庫等的值來設定。
控制組件16是從軸力感測器18-1、18-2、…、18-n取得軸力的檢測結果(S3)，並且將檢測結果與目標軸力或設定軸力作比較(S4)。此軸力的比較是按每個鎖緊處來進行。並且，在檢測結果與目標軸力或設定軸力有差分的情況下(S5的「是(YES)」)，則利用檢測到的軸力F的值來算出第2扭矩係數即補正扭矩值k2(S6)。又，在檢測結果與目標軸力或設定軸力沒有差分的情況下(S5的「否(NO)」)，則判斷已設定與鎖緊處的狀態相對應的扭矩係數k1，而維持第1扭矩係數k1(S7)。
控制組件16是按每個鎖緊處而利用各別的扭矩係數來算出鎖緊扭矩值T1、T2並設定於鎖緊工具14(S8)，再進行到下一個鎖緊順序。In terms of sealing construction management processing, the control module 16 uses the target axial force or the set axial force and the first torque coefficient k1 to calculate or select the first locking torque value T1 (S1), and locks this first locking The torque value T1 is set in the lock tool 14 (S2). The target axial force is a target value of the axial force F acting on the bolt 6 or the nut 8 when the locking is completed. When the tightening torque value T1 for the bolt 6 and the nut 8 is changed in stages according to the number of rounds S, the set axial force will be the value of the axial force F set when the tightening torque value T1 is calculated. It can be set to x [%] of the target axial force according to, for example, the number of tours S. The locking torque value T1 may be set by selecting a value stored in a database or the like in advance.
The control unit 16 obtains the detection results of the axial force from the axial force sensors 18-1, 18-2, ..., 18-n (S3), and compares the detection results with the target axial force or the set axial force (S4). This axial force comparison is performed for each locking position. When the detection result is different from the target axial force or the set axial force (YES in S5), the value of the detected axial force F is used to calculate the correction torque value k2, which is the second torque coefficient. (S6). When there is no difference between the detection result and the target axial force or the set axial force (NO in S5), it is determined that the torque coefficient k1 corresponding to the state of the locked position is set, and the first Torque coefficient k1 (S7).
The control unit 16 calculates the locking torque values T1 and T2 by using the respective torque coefficients for each locking place, sets the locking torque values T1 and T2, and proceeds to the next locking sequence.

再者，在此密封施工管理處理中，雖然是顯示了將檢測到的軸力與目標軸力或設定軸力作對比，並在其值有差分的情況下進行扭矩係數的補正之情況，但是並不限定於此。亦可根據在全部的鎖緊處檢測到的軸力，來算出第2扭矩係數k2。
又，在檢測到的軸力之對比處理中，並不限定於例如目標軸力或設定軸力，亦可與事先設定之規定的閾值作比較。Moreover, in this sealing construction management process, although the detected axial force is compared with the target axial force or the set axial force, and the torque coefficient is corrected when there is a difference, it is shown that Not limited to this. The second torque coefficient k2 can also be calculated from the axial force detected at all the lock points.
The comparison processing of the detected axial forces is not limited to, for example, a target axial force or a set axial force, and may be compared with a predetermined threshold value set in advance.

>鎖緊順序及巡迴次數>
圖6是顯示螺栓及螺帽的鎖緊順序之一例。
在螺栓6及螺帽8的鎖緊作業中，例如可如圖6之A的箭頭a所示，依序巡迴於位置P1、P2…、Pn，亦可如圖6之B的箭頭b所示，以在凸緣10-1、10-2的直徑方向上變更鎖緊處，即所謂的「對角鎖緊」鎖緊順序，巡迴於位置P1、P2…、Pn來進行鎖緊。亦即，可於位置P1、P2…、Pn依編號順序來連續鎖緊，亦可規則地跳過規定數之鎖緊處來巡迴。從而，巡迴次數S並不限定於對位置P1、P2…、Pn依照順序連續進行之巡迴的計數值，亦可為以跳過規定位置之巡迴為單位所計數的計數值。

FIG. 6 shows an example of a tightening sequence of a bolt and a nut.
In the locking operation of the bolt 6 and the nut 8, for example, as shown by arrow a in FIG. 6A, it can be sequentially toured at the positions P1, P2, ..., Pn, or as shown by arrow b in FIG. 6B. In order to change the locking position in the diameter direction of the flanges 10-1, 10-2, the so-called "diagonal locking" locking sequence, patrol the positions P1, P2, ..., Pn for locking. That is, the positions P1, P2, ..., Pn can be continuously locked in the order of numbers, and a predetermined number of locked positions can be regularly skipped to tour. Therefore, the number of rounds S is not limited to the counted value of the rounds that are continuously performed in sequence for the positions P1, P2, ..., Pn, and may be a counted value that is counted in units of rounds that skip the predetermined positions.
In the sealing construction management of this embodiment, for example, a locking sequence using a flange joint locking method (JIS B 2251) according to the Japanese Industrial Standards (JIS) is adopted. In this embodiment, for example, a case where the number of bolts 6 provided in the flanges 10-1 and 10-2 is n = 8 [branch] is shown. Therefore, in this locking process, in the so-called "temporary locking" stage from the start of locking until it reaches a predetermined number of tours (S), the flanges 10- at positions P1, P2, ..., Pn are performed. 1, 10-2 change the locking position in the diameter direction, which is the so-called "diagonal locking" (Figure 6B) locking. In addition, in the locking process, after the number of "temporary locking" patrols (S) is completed, as the so-called "main locking" phase, it is performed in sequence from P2 to Pn (A in Fig. 6). Lock it up.
Furthermore, the number of steps (STEP) or the order of "temporary locking" or "main locking" may be set differently depending on the number of bolts 6 provided on the flanges 10-1 and 10-2. Value.

>鎖緊指示資訊表40>
圖7是顯示鎖緊指示資訊表之一例。
此鎖緊指示資訊表40是儲存有密封施工管理的處理內容的表格之一例，且儲存於例如控制組件16中。在此鎖緊指示資訊表40中，保存有例如每個表示巡迴次數的「STEP」之「實施內容」的資訊或鎖緊的「順序」的資訊等。圖7所示的鎖緊指示資訊表40的「STEP」是依進行鎖緊的螺栓6的數量來決定，例如巡迴次數S＝10[次]，亦即，針對8[支]螺栓6及螺帽8以規定的順序分成10[次]來鎖緊。在此鎖緊指示中，例如在STEP3與STEP7中算出扭矩係數，並進行與鎖緊處的狀態相因應的扭矩係數之補正。

在「順序」的資訊中，保存有鎖緊螺栓6及螺帽8的手法。> Locking instruction information sheet 40>
FIG. 7 shows an example of a lock instruction information table.
This lock instruction information table 40 is an example of a table storing the processing contents of the sealed construction management, and is stored in, for example, the control unit 16. In this lock instruction information table 40, for example, information on the "implementation content" of "STEP" indicating the number of tours or information on the "sequence" of lock are stored. The “STEP” of the locking instruction information table 40 shown in FIG. 7 is determined according to the number of bolts 6 to be locked, for example, the number of tours S = 10 [times], that is, for 8 [brackets] of the bolts 6 and the screws The cap 8 is divided into 10 [times] and locked in a predetermined order. In this locking instruction, for example, the torque coefficient is calculated in STEP3 and STEP7, and the torque coefficient is corrected in accordance with the state of the locking place.
The information of the “implementation content” includes, for example, a value of a tightening torque value or a torque coefficient, an instruction for receiving a detected axial force, and an instruction for calculating a torque coefficient.
In the "sequence" information, the method of locking the bolt 6 and the nut 8 is stored.

>軸力的檢測結果>
圖8是顯示軸力的檢測結果之一例。
在控制組件16中具備有資訊表，前述資訊表包含從軸力感測器18-1、18-2、…、18-n取得之各鎖緊處的軸力F的值。圖8所示的資訊表是算出例如扭矩係數k的補正值之巡迴次數(S)中之軸力的檢測及鎖緊扭矩值或扭矩係數的算出結果，並且儲存有設定於鎖緊工具14的鎖緊扭矩值T1、作用於螺栓6或螺帽8的設定軸力Fx、檢測軸力F、補正前的扭矩係數k1、補正扭矩係數k2、補正扭矩值T’等。
鎖緊扭矩值T1是利用以此巡迴次數設定的設定軸力Fx、扭矩係數k1，而根據已提過的數式(1)來算出的值。例如在密封施工管理處理方面，控制組件16會將設定軸力Fx與以鎖緊扭矩值T1鎖緊時的軸力F作比較，並且在這些值並非一致或相對於設定軸力Fx並非在規定的範圍之情況下，算出補正扭矩係數k2。
並且，控制組件16會針對軸力的比較結果，設定在下一個巡迴次數中設定於鎖緊工具14的補正扭矩值T’。
再者，資訊表亦可例如按每個鎖緊巡迴次數來製作，或亦可僅在進行扭矩係數的補正的巡迴次數(S)時製作。> Axial Force Test Results>
FIG. 8 shows an example of the detection result of the axial force.
The control unit 16 is provided with an information sheet including the values of the axial force F at each locking position obtained from the axial force sensors 18-1, 18-2, ..., 18-n. The information table shown in FIG. 8 calculates, for example, the detection result of the axial force in the number of rounds (S) of the correction value of the torque coefficient k and the calculation result of the locking torque value or the torque coefficient. The tightening torque value T1, the set axial force Fx acting on the bolt 6 or the nut 8, the detected axial force F, the torque coefficient k1 before correction, the correction torque coefficient k2, the correction torque value T ', and the like.
The locking torque value T1 is a value calculated based on the formula (1) already mentioned using the set axial force Fx and the torque coefficient k1 set by the number of rounds. For example, in terms of sealing construction management processing, the control component 16 compares the set axial force Fx with the axial force F when locked with the tightening torque value T1, and these values are not consistent or are not specified relative to the set axial force Fx. In the case of the range, the correction torque coefficient k2 is calculated.
In addition, the control unit 16 sets the correction torque value T ′ set to the locking tool 14 in the next number of rounds for the comparison result of the axial force.
In addition, the information table may be prepared, for example, for each number of locked tours, or may be created only when the number of tours (S) of torque coefficient correction is performed.

>扭矩係數的算出結果>
圖9是顯示扭矩係數的算出結果之一例。

In the confirmation process, for example, the number of eight bolts 6 located at eight of the lock points P1 to P8 and the change in the detected axial force are used to identify each lock point P. The number of rounds (S) is specified by, for example, the tightening of the bolts 6 at eight locations, and is specified by the number of rounds of the same bolt 6.

控制組件16在已判斷巡迴次數(S)並非扭矩係數的算出步驟的情況下(S15的「否」)，則返回S12，加計巡迴次數(S)並設定與巡迴次數(S)相因應的軸力F或鎖緊扭矩值，來進行鎖緊處理。The control unit 16 determines whether the number of tours (S) has reached the step of calculating the torque coefficient (S15). In the case of the step of calculation (YES in S15), it performs a comparison between the detected axial force F and the set axial force Fx, And the calculation of the correction torque coefficient k2 for each bolt 6 (S16). In addition, the control unit 16 associates the calculated correction torque coefficient k2 for each bolt 6 (S17), and uses the established bolt coefficient k2 in the calculation of the next tightening torque value T.
When the control unit 16 has determined that the number of tours (S) is not a step of calculating the torque coefficient (NO in S15), it returns to S12, adds the number of tours (S), and sets the axis corresponding to the number of tours (S). Force F or locking torque value for locking processing.

例如圖15之A所示，在控制器52的顯示部60或伺服器54的螢幕68中，顯示有模擬密封施工部4的鎖緊處P1、P2…、Pn的鎖緊結果之畫面。此鎖緊結果的畫面是將控制器52或伺服器54之任一者或兩者從軸力感測器18-1、18-2、…、18-n取得的檢測結果(圖15之B)的資訊、及鎖緊工具14的鎖緊處或巡迴次數(S)的資訊等組合來生成的。

FIG. 15 shows an example of a locking result.
For example, as shown in FIG. 15A, the display portion 60 of the controller 52 or the screen 68 of the server 54 displays a screen that simulates the locking results of the locking portions P1, P2,..., Pn of the sealing construction portion 4. The screen of the locking result is the detection result obtained by either or both of the controller 52 or the servo 54 from the axial force sensors 18-1, 18-2, ..., 18-n (FIG. 15B ), And the locking position of the locking tool 14 or information about the number of rounds (S).
In the lock result screen, for example, for each lock position, the target shaft force for lock and the lock force for each number of tours (S) are displayed. That is, in the screen of the locking result, together with the deviation of the axial forces of the locking points, the change of the locking force for each number of tours (S) is also displayed.
In addition, as shown in FIG. 15B, for example, test data is stored in the temporary storage unit 94-1 of the controller 52 or the storage unit 114 of the server 54 as a test result. That is, the axial force F of the bolt 6 for each tour (S).
This test result shows the locking results of, for example, STEP1 ~ 6, and by further performing the locking step, the test data will increase. In this sealing construction management, for example, similar to the second embodiment, a torque coefficient correction process is performed based on the detection result of STEP3. In addition, after the correction of the torque coefficient, when the number of locked tours (S) is advanced, the detection result of the axial force of each bolt in the STEP6 stage becomes almost the same value. This shows the case where the flanges 10-1 and 10-2 are sealed with the axial force without deviation.

>密封施工管理的處理序列>
圖16是顯示由密封施工管理系統50所進行之密封施工管理的處理序列。
在密封施工處理中，會由鎖緊工具14進行初始設定(S31)，並且由控制器52進行初始設定(S32)。在此初始設定之後，使控制器52與伺服器54連線，控制器52會接收由伺服器54所提供之包含扭矩係數k1等的鎖緊條件資訊(S33)。控制器52是藉由鎖緊指示資訊表40的取得來接收鎖緊條件資訊。
已取得此鎖緊條件資訊的控制器52會選定與事先選定的凸緣10-1、10-2及墊片12相對應的鎖緊條件(S34)。又，控制器52會進行巡迴次數S或鎖緊位置P的設定(S35)、或是利用了扭矩係數k1或設定軸力Fx之鎖緊扭矩值T1的算出(S36)。在事先保存有鎖緊扭矩值T1的候補之情況下，只要選定此已保存的鎖緊扭矩值T1的1個即可。
經過鎖緊的準備處理後，控制器52會對鎖緊工具14設定鎖緊扭矩值T1(S37)。> Processing sequence for sealed construction management>
FIG. 16 shows a processing sequence of the sealing construction management performed by the sealing construction management system 50.
In the sealing construction process, the initial setting is performed by the locking tool 14 (S31), and the initial setting is performed by the controller 52 (S32). After this initial setting, the controller 52 is connected to the server 54 and the controller 52 receives the locking condition information including the torque coefficient k1 and the like provided by the server 54 (S33). The controller 52 receives the lock condition information by obtaining the lock instruction information table 40.
The controller 52 that has obtained this locking condition information selects a locking condition corresponding to the flanges 10-1, 10-2 and the gasket 12 selected in advance (S34). In addition, the controller 52 performs setting of the number of tours S or the locking position P (S35), or calculation of the locking torque value T1 using the torque coefficient k1 or the set axial force Fx (S36). In the case where a candidate for the tightening torque value T1 is stored in advance, only one of the saved tightening torque values T1 may be selected.
After the locking preparation process, the controller 52 sets a locking torque value T1 to the locking tool 14 (S37).

然後，施工人員會藉由鎖緊工具14，將鎖緊扭矩賦與於鎖緊處的螺栓6或螺帽8來進行鎖緊(S38)。各軸力感測器18-1、18-2、…、18-n會進行各鎖緊處P的螺栓6的軸力之檢測(S39)，並且該等檢測軸力F會被接收至控制器52(S40)。Then, the construction worker locks the bolt 6 or the nut 8 with the tightening torque to the lock by the lock tool 14 (S38). Each of the axial force sensors 18-1, 18-2, ..., 18-n will detect the axial force of the bolt 6 at each locking point P (S39), and the detected axial force F will be received to control器 52 (S40).

控制器52會利用各檢測軸力且由鎖緊處P的巡迴次數S或鎖緊處P的資訊來判斷鎖緊作業是否完成(S41)。亦即，控制器52在例如鎖緊處P＝8的情況下，會由8支螺栓6的編號與軸力的變化來特定出是鎖緊處P1~P8的哪一個。控制器52是以從鎖緊處P1~P8選擇的複數個螺栓6的鎖緊為單位，將已選擇的螺栓巡迴一次的次數設為巡迴次數S＝1。並且，如已提過的內容，巡迴次數S可以特定S＝0至n。The controller 52 judges whether the locking operation is completed by using each of the detected axial forces and the information of the number of rounds S of the locking place P or the locking place P (S41). That is, when the locking position P = 8, for example, the controller 52 specifies which of the locking positions P1 to P8 is based on the number of the eight bolts 6 and the change in the axial force. The controller 52 sets the number of rounds of the selected bolts once as the number of rounds S = 1 by taking the locking of the plurality of bolts 6 selected from the locking points P1 to P8 as a unit. And, as already mentioned, the number of tours S can be specified from S = 0 to n.

控制器52在已判斷鎖緊作業未完成的情況下(S41的「否」)，會判斷是否為扭矩係數k的算出步驟(巡迴次數)(S42)。為算出步驟的情況下(S42的「是」)，控制器52會判斷檢測軸力與設定軸力是否不同(S43)。
在不是扭矩係數k的算出步驟的情況下(S42的「否」)，且，在檢測軸力與設定軸力並無不同的情況下(S43的「否」)，返回S35來繼續鎖緊作業。
此時，在控制器52中，例如會加計巡迴次數(S)，並且算出與下一個巡迴次數相對應的鎖緊扭矩值T。藉此，因應於鎖緊處P或巡迴次數S而分階段地或連續地變更、設定輸出扭矩T。When the controller 52 has determined that the locking operation is not completed (No in S41), it determines whether or not it is the step (the number of rounds) for calculating the torque coefficient k (S42). In the case of a calculation step (YES in S42), the controller 52 determines whether the detected axial force is different from the set axial force (S43).
If it is not the step of calculating the torque coefficient k (No in S42), and if the detected axial force is not different from the set axial force (No in S43), return to S35 to continue the locking operation. .
At this time, in the controller 52, for example, the number of rounds (S) is added, and a locking torque value T corresponding to the next round of rounds is calculated. Thereby, the output torque T is changed or set in stages or continuously in accordance with the locking point P or the number of rounds S.

控制器52在已判斷檢測軸力與設定軸力不同的情況下(S43的「是」)，作為鎖緊扭矩值的補正處理，會算出利用了軸力的檢測結果之補正扭矩係數k2(S44)。並且，控制器52會設定包含補正扭矩係數k2之新的鎖緊條件(S45)，並且返回S35來繼續鎖緊處理。When the controller 52 has determined that the detected axial force is different from the set axial force (YES in S43), the controller 52 calculates the correction torque coefficient k2 using the detection result of the axial force as the correction processing of the locking torque value (S44 ). Then, the controller 52 sets a new locking condition including the corrected torque coefficient k2 (S45), and returns to S35 to continue the locking process.

控制器52在根據巡迴次數S的計數值而判斷鎖緊完成的情況下(S41的「是」)，會成為鎖緊結束(S46)，並且將鎖緊完成指示輸入至鎖緊工具14而完成鎖緊。此鎖緊完成只要利用例如螢幕68來提示即可。控制器52會將鎖緊結果資訊通知給伺服器54。然後，在伺服器54中會進行鎖緊結果資訊的顯示(S47)。When the controller 52 determines that the locking is completed based on the count value of the number of patrols S (YES in S41), the locking is completed (S46), and the locking completion instruction is input to the locking tool 14 to complete Lock it up. This locking is completed as long as the screen 68 is used for prompting. The controller 52 notifies the server 54 of the locking result information. Then, the server 54 displays the locking result information (S47).

再者，雖然控制器52是判斷巡迴次數(S)的計數來作為鎖緊是否完成的判斷，但並不限定於此。控制器52亦可針對例如從軸力感測器18-1、18-2、…、18-n取得的檢測結果，在判斷出軸力的偏差或未達到目標軸力或是不在規定的範圍內之情況下，更進一步地重複再上緊處理。In addition, although the controller 52 determines the count of the number of rounds (S) as the determination of whether the locking is completed, it is not limited to this. The controller 52 may also determine, for example, the detection results obtained from the axial force sensors 18-1, 18-2, ..., 18-n that the deviation of the axial force does not reach the target axial force or is out of a predetermined range. Within the case, the tightening process is repeated further.

>第3實施形態的效果>
根據這樣的構成，可得到如下的效果。
(1)由於可自動地選擇扭矩係數k或鎖緊扭矩值T等之鎖緊條件，因此無須強制作業人員進行鎖緊條件的管理，而能夠由鎖緊條件設定來減輕作業人員的負擔。可以避免抑賴於作業人員的經驗或直覺之鎖緊條件的設定，並且防止設定失誤或鎖緊失誤。
(2)由於可以將此鎖緊條件從伺服器54個別且具體地提供至控制器52，因此可以實現精細的鎖緊結果。可以根據軸力的檢測結果來進行扭矩係數k的補正或鎖緊扭矩值的設定等之精確度高的密封施工管理。
(3)藉由可進行鎖緊管理的鎖緊工具、及利用了電腦的資訊處理，即可以實現密封施工的自動化、高精確度化、簡單化、高效率化，且可以進行不依賴作業人員的經驗或直覺之信賴性高的密封施工。> Effects of the third embodiment>
According to such a configuration, the following effects can be obtained.
(1) Since the locking conditions such as the torque coefficient k or the locking torque value T can be automatically selected, there is no need to force the operator to manage the locking conditions, but the setting of the locking conditions can reduce the burden on the workers. It can avoid setting the locking conditions that depend on the experience or intuition of the operator, and prevent setting errors or locking errors.
(2) Since this locking condition can be individually and specifically provided from the server 54 to the controller 52, a fine locking result can be achieved. According to the detection result of the axial force, it is possible to perform high-precision sealing construction management such as correction of the torque coefficient k or setting of the tightening torque value.
(3) Locking tools that can perform lock management and information processing using a computer can realize seal construction automation, high accuracy, simplification, and efficiency, and can be performed independently of operators The experience or intuition of high reliability seal construction.

[Comparative example]

圖18是顯示凸緣的密封施工處理之比較例。
在圖18所示的密封施工管理處理中，例如和上述第2實施形態及第3實施形態同樣地，針對凸緣10-1、10-2進行鎖緊8支螺栓6與螺帽8的處理。此鎖緊處理是在設定於鎖緊工具14的鎖緊扭矩值T的出算處理中，維持0.2的值來作為事先設定的扭矩係數k之情況。並且，因應於巡迴次數，使鎖緊扭矩值T分階段地增加。
如圖18之A所示，由此鎖緊處理的結果可知，鎖緊位置P6的軸力總是比其他鎖緊位置有較大的軸力F在作用。並且，在巡迴次數即STEP6中，只有鎖緊位置P6達到目標軸力，相對於此，其他鎖緊處並未達到目標軸力。
如圖18之B所示，軸力感測器18-1、18-2、…18-8檢測到的軸力在STEP6的階段中，變成在各螺栓6間有較大的偏差之結果。將這些軸力值作比較後，偏差的最大值約為28[%]，而平均成為14[%]之值。產生了像這種偏差之情況下，由於力並未均等地作用在凸緣10-1、10-2間，因此會有發生只有一部分的鎖緊位置作用，也就是所謂的不均勻鎖緊，或在其他螺栓6及螺帽8發生鬆動的疑慮。因此，在鎖緊處理中，會變成例如一邊監視全部的螺栓6的軸力，一邊進行重新上緊或再上緊。在螺栓6及螺帽8對凸緣10-1、10-2的鎖緊中，如發明的課題所述，因彈性相互作用的影響，會受到其他螺栓的鎖緊發生鬆動等之影響，因此鎖緊後的軸力調整將會導致作業負荷的增加。FIG. 18 is a comparative example showing the sealing construction process of the flange.
In the sealing construction management process shown in FIG. 18, for example, the same processes as those in the second embodiment and the third embodiment described above are performed to lock the eight bolts 6 and the nuts 8 with respect to the flanges 10-1 and 10-2. . This locking process is a case where a value of 0.2 is maintained as a preset torque coefficient k in the calculation process of the locking torque value T set in the locking tool 14. In addition, the tightening torque value T is increased in stages in accordance with the number of rounds.
As shown in FIG. 18A, it can be known from the result of the locking process that the axial force at the locking position P6 always has a larger axial force F at the other locking positions. Moreover, in the number of tours, STEP6, only the locking position P6 has reached the target axial force, while other locking places have not reached the target axial force.
As shown in FIG. 18B, the axial force detected by the axial force sensors 18-1, 18-2, ... 18-8 becomes a result of a large deviation between the bolts 6 in the STEP6 stage. After comparing these axial force values, the maximum deviation is about 28 [%], and the average value becomes 14 [%]. In the case of such a deviation, since the force is not applied equally between the flanges 10-1 and 10-2, only a part of the locking position will occur, which is called uneven locking. Or there is a concern that the bolts 6 and nuts 8 are loose. Therefore, in the locking process, for example, it is re-tightened or re-tightened while monitoring the axial force of all the bolts 6. In the locking of the flanges 10-1 and 10-2 by the bolts 6 and the nuts 8, as described in the subject of the invention, the elastic interaction affects the locking of other bolts, such as loosening. Adjustment of the axial force after locking will increase the working load.

相對於此，如本發明所述，在鎖緊步驟中進行與鎖緊處相對應的扭矩係數的補正處理，藉此就不會產生螺栓6間的鎖緊狀態的偏差所造成的影響，或是可抑制該影響，因此會變得有效率且作業負荷變少，並且變得可進行鎖緊狀態穩定的密封施工管理。On the other hand, as described in the present invention, in the locking step, a correction process of the torque coefficient corresponding to the locked portion is performed, so that the influence caused by the deviation of the locked state between the bolts 6 is not generated, or Since this effect can be suppressed, it becomes effective and the work load becomes small, and it becomes possible to perform sealing construction management with a stable locking state.

[其他的實施形態][Other embodiments]

(1)在上述實施形態中，雖然顯示了使用具備處理器等的手持鎖緊機來作為鎖緊工具14之情況，但並不限於此。鎖緊工具14亦可使用例如能以手動方式設定鎖緊扭矩的扭矩扳手。又，鎖緊工具14只要是大型的組裝裝置，且是具有進行螺栓的鎖緊之鎖緊臂部，並且可進行針對製品的鎖緊處之掌握或檢測由鎖緊所造成的軸力之裝置即可。(1) In the above-mentioned embodiment, although the case where the hand-held locking machine provided with a processor etc. was used as the locking tool 14 was shown, it is not limited to this. As the lock tool 14, for example, a torque wrench capable of manually setting the lock torque can be used. In addition, as long as the locking tool 14 is a large-scale assembly device, it is a device that has a locking arm that performs bolt locking, and can grasp or detect the axial force caused by the locking of the product at the locking place. Just fine.

(2)在上述實施形態中，雖然顯示了在螺栓本身設置有軸力感測器，來作為檢測作用於鎖緊處的軸力之組件，但並不限於此。在密封施工管理處理中，亦可針對例如已鎖緊的螺栓6，利用超音波感測器等之檢測機器來檢測軸力，並且利用此檢測結果來算出扭矩係數。(2) In the above-mentioned embodiment, although it is shown that the bolt itself is provided with an axial force sensor as a component for detecting the axial force acting on the locking place, it is not limited to this. In the sealing construction management process, for example, the axial force may be detected by a detection device such as an ultrasonic sensor with respect to the bolt 6 that has been locked, and a torque coefficient may be calculated using the detection result.

(3)控制器52亦可使用例如智慧型手機等之手持資訊終端。(3) The controller 52 may also use a handheld information terminal such as a smart phone.

(4)在上述實施形態中，雖然顯示了將控制器52及伺服器54連線於一個鎖緊工具14的例子，但並不限於此。亦可將控制器52及伺服器54連線於複數個鎖緊工具14，且亦可在複數個控制器52中具備單一的伺服器54。(4) In the above embodiment, the example in which the controller 52 and the server 54 are connected to one locking tool 14 is shown, but it is not limited to this. The controller 52 and the server 54 may also be connected to the plurality of locking tools 14, and a single server 54 may be provided in the plurality of controllers 52.
