Description
本發明,係與使用於對金屬帶實施熔融金屬電鍍後用以除去多餘之熔融金屬的氣刀裝置,而具有:擋板及用以調整其位置之位置調整機構的擋板單元及使用該擋板單元之氣刀裝置相關。The present invention relates to an air knife device for removing excess molten metal after performing molten metal plating on a metal strip, and has a baffle plate and a baffle unit for adjusting a position thereof, and a baffle unit for using the position adjusting mechanism The air knife unit of the board unit is related.
例如,於鋼帶之熔融鋅電鍍設備,將鋼帶浸漬於熔融鋅電鍍槽後,因為將鋼帶垂直向上拉起,而使鋼帶之表背面附著著熔融鋅,然而,在電鍍槽之正上方,則配置著對從電鍍槽向上拉起之鋼帶的表背面吹附氣體來除去多餘之熔融鋅的氣刀裝置。For example, in the molten zinc plating equipment of the steel strip, after the steel strip is immersed in the molten zinc plating bath, since the steel strip is pulled up vertically, the molten zinc is adhered to the back surface of the steel strip, however, in the plating tank Above, an air knife device that blows gas to the front and back surfaces of the steel strip pulled up from the plating tank to remove excess molten zinc is disposed.
此種氣刀裝置,於鋼帶之兩面側,沿著鋼帶之寬度方向,以互相相對之方式配設著長度大於鋼帶之寬度長度之一對氣刀噴嘴,從該等氣刀噴嘴對鋼帶吹附氣體。The air knife device is disposed on the two sides of the steel strip along the width direction of the steel strip, and opposite to each other, a pair of air knife nozzles having a length greater than a width of the steel strip, from the air knife nozzle pair The steel strip is blown with gas.
然而,於該氣刀裝置,從一對氣刀噴嘴所吹出之氣體衝擊比鋼帶之寬度方向更為外側的部分,而使氣體流動變亂,而減少鋼帶之邊緣部分的清除效果,而發生鋼帶邊緣部分之電鍍附著量較多之邊緣過塗現象。However, in the air knife device, the gas blown from the pair of air knife nozzles impacts the outer portion of the strip in the width direction, thereby causing the gas flow to be disordered, and reducing the cleaning effect of the edge portion of the steel strip. The edge of the steel strip is plated with a large amount of edge overcoating.
所以,氣刀噴嘴之設置位置,係將,被稱為側板、虛擬板、擋板等之阻擋板(以下,稱為擋板)配置於鋼帶之兩邊緣的外側,來迴避如上所述之氣體衝擊(專利文獻1、2、3等)。Therefore, the position of the air knife nozzle is such that a blocking plate (hereinafter referred to as a baffle plate) called a side plate, a virtual plate, a baffle plate or the like is disposed on the outer side of both edges of the steel strip, and is circumvented as described above. Gas shock (Patent Documents 1, 2, 3, etc.).
該擋板,為了抑制上述過塗現象,必須儘量接近鋼帶,要求接近到鋼帶只距離1mm程度之位置。此時,被電鍍鋼帶之寬度非為一定的話,擋板之設置位置,就必須對應鋼帶之寬度來進行調整。此外,即使鋼帶之寬度相同,因為搬送中之鋼帶會左右移動,而必須以擋板不會接觸鋼帶之方式來進行位置調整。In order to suppress the above overcoating phenomenon, the baffle plate must be as close as possible to the steel strip, and it is required to be close to the steel strip at a distance of only 1 mm. At this time, if the width of the plated steel strip is not constant, the position of the baffle must be adjusted corresponding to the width of the steel strip. In addition, even if the width of the steel strip is the same, since the steel strip in the conveyance moves left and right, the position adjustment must be performed in such a manner that the baffle does not contact the steel strip.
有鑑於以上諸點,上述專利文獻1時,係於擋板配設接觸滾輪,使其接觸鋼帶,來使擋板及鋼帶之距離保持一定。然而,該接觸式時,可能發生邊緣受損、或附著於鋼帶之邊緣部的鋅捲入接觸滾輪之問題。所以,需要使擋板不會接觸鋼帶之位置調整技術。In view of the above, in the above Patent Document 1, the contact roller is disposed on the baffle to contact the steel strip to keep the distance between the baffle and the steel strip constant. However, in this contact type, there is a possibility that the edge is damaged, or the zinc attached to the edge portion of the steel strip is caught in the contact roller. Therefore, there is a need for a position adjustment technique in which the baffle does not contact the steel strip.
為了實現該非接觸之位置調整,需要配設位置檢測器並用以檢測鋼帶之邊緣位置的技術,該技術如專利文獻4所示。專利文獻4時,係於鋼帶之兩側,以可以於鋼帶之寬度方向進行直線移動之方式,配設雷射反射式光電型檢測器作為位置檢測器,藉此,來檢測鋼帶之邊緣部。In order to realize the non-contact position adjustment, a technique of arranging a position detector and detecting the edge position of the steel strip is required, and the technique is as shown in Patent Document 4. In Patent Document 4, a laser reflection type photoelectric detector is provided as a position detector on both sides of the steel strip so as to be linearly movable in the width direction of the steel strip, thereby detecting the steel strip. Edge part.

然而,將上述專利文獻4之技術應用於以進行擋板之位置調整為目的之鋼帶的位置檢測時,因為位置檢測器為光學式,若因為鋅塵而發生塵霧的話,則無法使用。此外,此種光學式之位置檢測器,必須以接近檢測對象之鋼帶的方式來配置,而有附著於鋼帶之高溫熔融鋅之熱可能導致錯誤動作的疑慮。其次,上述問題,並未受限於對鋼帶實施熔融鋅電鍍時,於對金屬帶實施熔融金屬電鍍時,一般都會發生。However, when the technique of the above-mentioned Patent Document 4 is applied to the position detection of the steel strip for the purpose of adjusting the position of the baffle, since the position detector is optical, if dust mist occurs due to zinc dust, it cannot be used. Further, such an optical position detector must be disposed in such a manner as to be close to the steel strip to be detected, and there is a concern that the heat of the high-temperature molten zinc attached to the steel strip may cause an erroneous operation. Secondly, the above problems are not limited by the fact that when molten steel plating is applied to the steel strip, it is generally caused when the metal strip is subjected to molten metal plating.
所以,本發明之目的,係在提供一種擋板單元及使用該擋板單元之氣刀裝置,可以在不受熔融金屬所發生之塵煙及熱等之影響下,檢測金屬帶之位置並實施擋板之位置調整。Therefore, the object of the present invention is to provide a baffle unit and an air knife device using the baffle unit, which can detect the position of the metal strip and perform the block without being affected by the dust, heat and the like generated by the molten metal. The position of the board is adjusted.

A schematic view for explaining the arrangement of the air knife nozzle and the baffle of the air knife device, and Fig. 4 is a front view of the baffle unit according to an embodiment of the present invention.
第1圖,符號11,係用以儲存熔融鋅L之鋅槽,將鋼帶1斜向導入該鋅槽11內之熔融鋅L,利用配置於鋅槽11內之導輥12改變方向後,再經由同樣配置於鋅槽11內之支撐滾輪13從鋅槽11內之熔融鋅以垂直方向被向上拉起。被導入鋅槽11之鋼帶1,通過保持於非氧化環境之筒狀喙部15之內部被導入鋅槽11內。此外,於鋅槽11之上方,則配設著以除去以垂直方向被向上拉起之鋼帶1之多餘之熔融鋅的氣刀裝置20。In the first drawing, reference numeral 11 is a zinc tank for storing molten zinc L, and the molten steel L which is introduced into the zinc tank 11 obliquely in the zinc tank 11 is redirected by the guide rolls 12 disposed in the zinc tank 11. Further, the molten zinc in the zinc tank 11 is pulled up in the vertical direction via the support roller 13 disposed in the zinc tank 11 in the same manner.

Further, above the zinc tank 11, an air knife device 20 for removing excess molten zinc of the steel strip 1 which is pulled upward in the vertical direction is disposed.
氣刀裝置20,如第2圖及第3圖所示,係具備著:用以對鋼帶1之表面及裏面吹附氣體來除去附著於鋼帶1之多餘熔融鋅之一對之氣刀噴嘴21;及擋板單元24。As shown in FIGS. 2 and 3, the air knife device 20 is provided with an air knife for blowing a gas to the surface and the inside of the steel strip 1 to remove excess molten zinc attached to the steel strip 1. a nozzle 21; and a shutter unit 24.
氣刀噴嘴21,係由沿著鋼帶1之寬度方向而大於鋼帶1之寬度的長條體所構成,於其前端,則形成有朝鋼帶1吹出氣刀氣體之狹縫21a。The air knife nozzle 21 is formed of an elongated body that is larger than the width of the steel strip 1 along the width direction of the steel strip 1, and a slit 21a for blowing the air knife gas toward the steel strip 1 is formed at the tip end thereof.
擋板單元24,如第4圖所示,於氣刀噴嘴21之設置位置,具有:配設於鋼帶1之兩邊緣部外側之一對擋板22、及用以調整擋板22位置之位置調整機構23。As shown in FIG. 4, the baffle unit 24 has a pair of baffles 22 disposed outside the edge portions of the steel strip 1 and a position for adjusting the position of the baffle 22 at the position where the air knife nozzle 21 is disposed.

Specifically, the electromagnetic wave such as microwave is radiated toward the steel strip 1, and the electromagnetic wave reflected by the edge of the steel strip 1 is received, and the steel strip 1 is detected based on the time difference between the electromagnetic wave and the reflected electromagnetic wave. Edge position. In the present embodiment, the electromagnetic wave sensor unit 32 is capable of radiating a first electromagnetic wave having a relatively high frequency capable of high-precision detection and a second electromagnetic wave (carrier wave) having a relatively low frequency capable of performing stability detection. In this way, it is common to perform high-precision position detection using the first electromagnetic wave, and even if the first electromagnetic wave measurement is affected by peripheral noise, the second electromagnetic wave can be corrected to perform stable position detection. The electromagnetic wave is preferably a microwave. A good example is that, for example, the frequency of the first electromagnetic wave is 10 GHz, and the second frequency is 2.5 GHz.

檢測部38,係具有:傳送接收部43;例如,10GHz之電磁波之第1電磁波用之第1傳送接收天線44;以及例如,2.5GHz之電磁波之第2電磁波用之第2傳送接收天線45。該檢測部38,係藉由裝設於上述框架構件40之上面的支架41而固定於框架構件40,以與框架構件40之上面隔著適當距離來配設。例如,以框架構件40之上面至天線中心部為止之距離為800mm之方式來配設。另一方面,本體部37為了避免受到熱之影響,而配置於地上。The detection unit 38 includes a transmission/reception unit 43; for example, a first transmission/reception antenna 44 for the first electromagnetic wave of electromagnetic waves of 10 GHz; and a second transmission/reception antenna 45 for the second electromagnetic wave of electromagnetic waves of 2.5 GHz, for example. The detecting portion 38 is fixed to the frame member 40 by a bracket 41 attached to the upper surface of the frame member 40, and is disposed at an appropriate distance from the upper surface of the frame member 40. For example, the distance from the upper surface of the frame member 40 to the center of the antenna is 800 mm. On the other hand, the main body portion 37 is disposed on the ground in order to avoid being affected by heat.
檢測部38之第1傳送接收天線44及第2傳送接收天線45,係固定地配設於與鋼帶1之邊緣距離250~1000mm程度的位置。並且,從第1傳送接收天線44放射由本體部37所發生之特定頻率,例如,10GHz之電磁波,並以第1傳送接收天線44接收於鋼帶1之邊緣反射之電磁波,本體部37,則由放射時及接收時之時間差來演算位置資訊,並將該位置資訊傳送給控制部33。同樣地,由第2傳送接收天線45放射例如2.5GHz之電磁波,並以第2傳送接收天線45接收於鋼帶1之邊緣反射之電磁波,本體部37,則由放射時及接收時之時間差來演算位置資訊。再將該位置資訊傳送給控制部33。The first transmission/reception antenna 44 and the second transmission/reception antenna 45 of the detecting unit 38 are fixedly disposed at a position spaced apart from the edge of the steel strip 1 by about 250 to 1000 mm. Further, the first transmission/reception antenna 44 radiates a specific frequency generated by the main body unit 37, for example, an electromagnetic wave of 10 GHz, and receives the electromagnetic wave reflected by the edge of the steel strip 1 by the first transmission/reception antenna 44, and the main body portion 37 The position information is calculated from the time difference between the radiation and the time of reception, and the position information is transmitted to the control unit 33. Similarly, an electromagnetic wave of, for example, 2.5 GHz is radiated from the second transmission/reception antenna 45, and an electromagnetic wave reflected by the edge of the steel strip 1 is received by the second transmission/reception antenna 45, and the main body portion 37 is caused by the time difference between the radiation and the reception. Calculate location information. The position information is transmitted to the control unit 33.
電磁波纜線39之檢測部38側部分,係被固定於框架構件40,藉由連接器46,可裝卸於本體部37側之部分。藉此,擋板單元24之裝設時、及維修之拆除時,容易進行框架構件40之裝卸。而且,不希望有傳送高頻之電磁波纜線之中繼時,以將配設在本體部37之生成電磁波(高頻)的部分配設於檢測部38,再以通常之纜線連結本體部37及檢測部38,並於該處配設連接器為佳。The side of the detecting portion 38 of the electromagnetic wave cable 39 is fixed to the frame member 40, and is detachably attached to the main body portion 37 side by the connector 46. Thereby, the attachment and detachment of the frame member 40 can be easily performed at the time of installation of the shutter unit 24 and the removal of the maintenance. Further, when it is not desired to relay the high-frequency electromagnetic wave cable, the portion where the electromagnetic wave (high frequency) is generated in the main body portion 37 is disposed in the detecting portion 38, and the main body portion is connected by a normal cable. 37 and the detecting portion 38, and it is preferable to provide a connector there.
控制部33,係收來自電磁波感測器單元32之鋼帶1之邊緣位置的資訊,並依據該信號,對作動器35輸出控制信號,並以使擋板22位於接近鋼帶1邊緣之特定位置的方式來進行控制。電磁波感測器單元32之精度確認及校準上,係於軌道上裝設虛擬鋼帶,利用可移動虛擬鋼帶之校正夾具。具體而言,初期狀態或鋼帶寬度等條件變更時,於一對之檢測部38之間設置校正夾具,並使虛擬鋼帶之邊緣位於距離天線500mm之位置,來實施1點校正,此外,利用感測器單元32實際檢測虛擬鋼帶之邊緣來實施感測器之精度確認。此外,利用虛擬鋼帶,也可實施垂直於各擋板22之鋼帶1之主面之方向的位置調整。The control unit 33 receives information on the edge position of the steel strip 1 from the electromagnetic wave sensor unit 32, and outputs a control signal to the actuator 35 in accordance with the signal, so that the shutter 22 is located near the edge of the steel strip 1. The way the location is controlled. In the accuracy verification and calibration of the electromagnetic wave sensor unit 32, a virtual steel strip is mounted on the track, and a calibration jig for the movable virtual steel strip is used. Specifically, when the conditions such as the initial state or the width of the steel strip are changed, a correction jig is provided between the pair of detecting portions 38, and the edge of the virtual steel strip is placed at a position of 500 mm from the antenna to perform one-point correction. The accuracy of the sensor is verified by the sensor unit 32 actually detecting the edge of the virtual steel strip. Further, the positional adjustment in the direction perpendicular to the main surface of the steel strip 1 of each of the baffles 22 can be performed by the dummy steel strip.
其次,針對本實施方式之氣刀裝置的動作進行說明。Next, the operation of the air knife device of the present embodiment will be described.
首先,於鋅槽11之上方的特定位置,設置氣刀裝置20。具體而言,將氣刀噴嘴21設置於特定位置後,再將擋板單元24設置於特定位置。First, the air knife device 20 is disposed at a specific position above the zinc tank 11. Specifically, after the air knife nozzle 21 is set at a specific position, the shutter unit 24 is placed at a specific position.
其後,利用具有可動式之虛擬鋼帶的校正夾具,以使垂直於各擋板22之鋼帶1之主面之方向的位置符合路線之方式來進行調整,同時,進行電磁波感測器單元32之感測器之精度確認及校準。Thereafter, the correction jig having the movable virtual steel strip is used to adjust the position in the direction perpendicular to the main surface of the steel strip 1 of each of the baffles 22 in accordance with the route, and at the same time, the electromagnetic wave sensor unit is performed. Accuracy identification and calibration of 32 sensors.
其次,開始鋼帶1之熔融鋅電鍍處理,對從鋅槽11向上拉起之鋼帶1,藉由氣刀裝置20,除去鋼帶1之多餘熔融鋅。Next, the molten zinc plating treatment of the steel strip 1 is started, and the excess molten zinc of the steel strip 1 is removed by the air knife device 20 for the steel strip 1 pulled up from the zinc bath 11.
此時,為了解除鋼帶1之邊緣部分之電鍍附著量較多之邊緣過塗現象,藉由擋板單元24之位置調整機構23,以使擋板22接近鋼帶1之邊緣的方式,來調整擋板22之位置。位置調整機構23,係由配設於鋼帶1兩側之電磁波感測器單元32朝鋼帶1之邊緣放射電磁波,接收反射之電磁波並以非接觸方式檢測鋼帶1之邊緣位置。At this time, in order to release the edge overcoating phenomenon in which the plating portion of the steel strip 1 is excessively applied, the position adjusting mechanism 23 of the shutter unit 24 is used to bring the shutter 22 close to the edge of the steel strip 1, Adjust the position of the flapper 22. The position adjusting mechanism 23 radiates electromagnetic waves toward the edge of the steel strip 1 by the electromagnetic wave sensor unit 32 disposed on both sides of the steel strip 1, receives the reflected electromagnetic waves, and detects the edge position of the steel strip 1 in a non-contact manner.
傳統之擋板單元,於鋼帶之邊緣位置的檢測上,係利用光學感測器,然而,因為光學感測器之可測定距離較短,而必須將感測器配設於極為接近擋板之位置,容易因為鋅之塵煙附著於放射‧受光部而導致光量不足,而發生感測器無法正常動作而故障之情形。所以,必須頻繁地進行維修‧清掃。此外,因為將光學感測器配設於極為接近擋板之位置,故其必須為感測器與擋板一起移動之可動式,維修時,必須停止作業。此外,光學感測器不耐熱(高溫),配設於擋板之附近時,容易因為熱而產生錯誤檢測及故障等。The traditional baffle unit utilizes an optical sensor for detecting the edge position of the steel strip. However, since the optical sensor can measure a short distance, the sensor must be disposed very close to the baffle. At the position, it is easy to cause the amount of light to be insufficient due to the adhesion of the zinc dust to the radiation/light-receiving portion, and the sensor may not operate normally and malfunction. Therefore, maintenance must be carried out frequently and cleaned. In addition, since the optical sensor is disposed in a position very close to the baffle, it must be a movable type in which the sensor moves together with the baffle, and must be stopped during maintenance. In addition, the optical sensor is not heat-resistant (high temperature), and when it is disposed near the shutter, it is easy to cause erroneous detection, malfunction, and the like due to heat.
相對於此,本實施方式之擋板單元24時,使用於位置調整機構23之電磁波感測器,因為在原理上,其測定距離較長,且為高精度,故檢測部38從檢測對象之鋼帶距離1000mm程度之位置也可以高精度進行檢測。所以,可以將檢測部38固定地配設於鋼帶1之邊緣及距離鋅槽11較遠之位置,可以在減少受到高溫鋼帶1之熱影響及鋅塵煙等之影響的環境下,實施鋼帶1之邊緣的位置檢測。同時,也有電磁波(微波)幾乎不會受到氣體之溫度、壓力、流速變化、粉塵等之影響的優點。是以,本實施方式所使用之電磁波感測器單元32,在原理上,相較於光學感測器,更為能承受熱及塵煙等,而且,設置環境所承受到之熱及塵煙的影響也較少,故可以高精度來實施鋼帶1之位置測定,同時,可以謀求長壽命化。實際上,利用放射頻率為10GHz之電磁波(微波)的電磁波感測器來控制擋板之位置,結果,對於擋板22及鋼帶1邊緣之間之目標的間隙,可以達到±1.0mm。On the other hand, in the baffle unit 24 of the present embodiment, the electromagnetic wave sensor used in the position adjustment mechanism 23 has a long measurement distance and is highly accurate. Therefore, the detection unit 38 is from the detection target. The position of the steel strip at a distance of 1000 mm can also be detected with high precision. Therefore, the detecting portion 38 can be fixedly disposed at the edge of the steel strip 1 and at a position far from the zinc bath 11, and the steel can be implemented in an environment that is less affected by the heat of the high-temperature steel strip 1 and the zinc dust. Position detection with the edge of 1. At the same time, electromagnetic waves (microwaves) are hardly affected by the temperature, pressure, flow rate change, dust, and the like of the gas. Therefore, the electromagnetic wave sensor unit 32 used in the present embodiment is more capable of withstanding heat and dust smoke than the optical sensor, and is also provided with the influence of heat and dust emitted by the environment. Since it is also small, the position measurement of the steel strip 1 can be performed with high precision, and the life can be extended. Actually, the electromagnetic wave sensor of the electromagnetic wave (microwave) having a radiation frequency of 10 GHz is used to control the position of the baffle, and as a result, the gap between the target between the baffle 22 and the edge of the steel strip 1 can be made ±1.0 mm.
此外,電磁波感測器單元32,如上面所述,因為不易受到溫度及粉塵等之影響,基本上,無需維修。即使需要維修時,因為檢測部38係固定地配設於離開鋼帶1邊緣較遠之位置,無需停止生產線即可進行維修。Further, the electromagnetic wave sensor unit 32, as described above, is basically not affected by temperature, dust, etc., and basically requires no maintenance. Even when maintenance is required, since the detecting portion 38 is fixedly disposed at a position far from the edge of the steel strip 1, maintenance can be performed without stopping the production line.
此外,電磁波感測器,因為具有高指向性,即使將電磁波感測器單元32之檢測部38配置於框架構件40上之狹窄部位且距離鋼帶1較遠之位置,也可不對周邊機器造成影響來進行安定之連續測定。此外,因為檢測部38係利用支架41裝設於支柱,即使人接近到某種程度,對測定的影響也極少。此外,電磁波感測器,即使寬度0.3mm程度之部位,只要電磁波能到達即可進行位置檢測,此外,因為不是邊緣1點之檢測,也不是範圍之檢測,故幾乎不會發生遺漏測定等之情形。Further, since the electromagnetic wave sensor has high directivity, even if the detecting portion 38 of the electromagnetic wave sensor unit 32 is disposed at a narrow portion on the frame member 40 and at a position far from the steel strip 1, the peripheral machine may not be caused. The effect is to perform a continuous measurement of stability. Further, since the detecting portion 38 is attached to the pillar by the bracket 41, even if the person approaches a certain degree, the influence on the measurement is extremely small. In addition, the electromagnetic wave sensor can detect the position as long as the electromagnetic wave can reach even if it has a width of about 0.3 mm. Moreover, since it is not the detection of one point on the edge, it is not the detection of the range, so that the measurement of the omission is hardly occurred. situation.
此外,電磁波感測器單元32之檢測部38,因為電子構件較少、強度足夠、不易故障,故具有長壽命,且可實現省維修化。此外,即使需要維修時,如上面所述,無需停止作業,很容易即可進行維修。Further, since the detecting portion 38 of the electromagnetic wave sensor unit 32 has a small number of electronic components, is sufficiently strong, and is not easily broken, it has a long life and can be saved in maintenance. In addition, even when maintenance is required, as described above, it is easy to perform maintenance without stopping the work.
此外,本實施方式之擋板單元24,於基礎構件之框架構件40,裝設有電磁波感測器單元23之檢測部38及作動器35,使擋板22沿著裝設於框架構件40之線性導引部沿移動來構成的話,就成為一體構造。所以,裝設擋板單元24時、及維修等而進行拆除時,可以一體進行,裝設及拆除都很容易,具高維修性。此外,此時,裝設於框架構件40之電磁波纜線39之檢測部側部分,因為可利用連接器46而與本體部37側部分進行相連及分離,藉由切離電磁波纜線39之本體部37側部分,很容易即可進行框架構件40之裝設拆除。Further, in the shutter unit 24 of the present embodiment, the detecting portion 38 of the electromagnetic wave sensor unit 23 and the actuator 35 are mounted on the frame member 40 of the base member, and the shutter 22 is linearly disposed along the frame member 40. When the guide portion is formed to move, it has an integral structure. Therefore, when the baffle unit 24 is installed and removed for maintenance, it can be integrated, and it is easy to install and remove, and has high maintainability. Further, at this time, the detecting portion side portion of the electromagnetic wave cable 39 mounted on the frame member 40 is connected and separated from the body portion 37 side portion by the connector 46, by cutting off the body of the electromagnetic wave cable 39. At the side portion of the portion 37, the attachment of the frame member 40 can be easily performed.
此外,鋼帶1之位置檢測上,藉由利用:可進行高精度檢測之例如10GHz之相對高頻的第1電磁波、及可進行安定檢測之例如2.5GHz之相對低頻的第2電磁波(載波)之2種頻率的電磁波,即使周邊雜訊(不需要之反射波)對第1頻率之測定產生影響時,也可以第2電磁波進行補正而實施安定之位置檢測。Further, in the position detection of the steel strip 1, a first electromagnetic wave having a relatively high frequency of, for example, 10 GHz capable of high-precision detection, and a second electromagnetic wave (carrier wave) having a relatively low frequency of, for example, 2.5 GHz capable of performing stable detection are used. When the electromagnetic waves of the two kinds of frequencies affect the measurement of the first frequency by the surrounding noise (unnecessary reflected waves), the second electromagnetic wave can be corrected to perform the position detection of the stability.
如以上所述,用以調整相對於擋板之金屬帶之寬度方向端部之位置的位置調整機構,利用具有分別檢測金屬帶之一對之寬度方向端部之位置之一對之電磁波感測器單元者,並將該檢測部固定地配設於與金屬帶之寬度方向端部隔著特定距離之位置,可以不受來自熔融金屬之塵煙及熱等的影響下,檢測金屬帶之位置並進行擋板之位置調整。As described above, the position adjusting mechanism for adjusting the position of the end portion in the width direction of the metal strip of the baffle utilizes electromagnetic wave sensing having one of the positions of the end portions in the width direction of one pair of the metal strips respectively. The unit is fixedly disposed at a position separated from the end portion in the width direction of the metal strip by a specific distance, and the position of the metal strip can be detected without being affected by dust, heat, or the like from the molten metal. Perform the position adjustment of the bezel.
此外,本發明,並未受限於上述實施方式,而可實施各種變形。例如,上述實施方式時,係將本發明適用於以對鋼帶實施熔融鋅電鍍之設備時為例,然而,並未受限於此,可以適用於對金屬帶實施熔融金屬電鍍時之全體。此外,上述實施方式時,係以檢測部38具有分別放射不同頻率之電磁波之2個天線為例,然而,亦可以由一個天線放射單一頻率之電磁波者。Further, the present invention is not limited to the above embodiments, and various modifications can be made. For example, in the above embodiment, the present invention is applied to an apparatus for performing molten zinc plating on a steel strip. However, the present invention is not limited thereto, and can be applied to all of the metal strips subjected to molten metal plating. Further, in the above embodiment, the detecting unit 38 has two antennas that radiate electromagnetic waves of different frequencies, but an electromagnetic wave of a single frequency may be radiated from one antenna.
