[Prior Art] For example, in a molten zinc plating apparatus for a steel strip, after the steel strip is immersed in a molten zinc plating bath, since the steel strip is pulled up vertically, the molten zinc is attached to the front and back sides of the steel strip, however, Immediately above the plating tank, 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. 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. 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. 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.).

At this time, if the width of the plated steel strip is not constant, the position of the baffle must be adjusted according to the width of the strip. Further, 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. 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. In order to realize the positional adjustment of the non-contact, 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.

The detecting unit 38 includes a transmitting/receiving unit 43; for example, a first transmitting/receiving antenna 44 for the first electromagnetic wave of electromagnetic waves of 10 GHz; and a second transmitting and receiving 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 set to be 800 mm. On the other hand, the main body portion 37 is disposed on the ground in order to avoid being affected by heat. 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 1 000 mm. Further, the first transmission/reception antenna 44 radiates a specific frequency generated by the main body portion 37, for example, an electromagnetic wave of 10 GHz, and receives electromagnetic waves 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 reception, and the position information is transmitted to the control unit 33. Similarly, an electromagnetic wave of, for example, 2.5 GHz is radiated by 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. The side of the detecting portion 38 of the electromagnetic wave cable 39 is fixed to the frame member -11 - 201221691 40, and is detachably attached to the portion of the main body portion 37 by the connector 46. Thereby, the attachment and detachment of the frame member 40 can be easily performed when the shutter unit 24 is installed and when the maintenance is removed. 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. 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. For the accuracy verification and calibration of the electromagnetic wave sensor unit 32, a virtual steel strip is attached to the track, and a calibration clamp 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 confirmed 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. Next, the operation of the air knife device of the present embodiment will be described. First, the air knife device 20 is placed at a specific position above the zinc tank. Specifically, after the air knife nozzle 21 is set at a specific position, the shutter unit 24 is placed at a specific position. 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. 32 senses 201221691 accuracy and calibration of the device. 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 on the steel strip 1 which is pulled up from the zinc bath 11. 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. 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 dust of the zinc to the radiation/light-receiving portion, and the sensor may not operate normally and may malfunction. Therefore, it is necessary to perform maintenance and cleaning frequently. In addition, since the optical sensor is disposed in a position very close to the shutter, it must be movable for the sensor to move with the shutter, 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 and malfunction due to heat. 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. So, you can

S -13- 201221691 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, 更爲能承受熱及塵煙等,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,利用放射頻率爲 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 . 〇 m m。 此外,電磁波感測器單元32,如上面所述,因爲不易 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,因爲檢測部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。 此外,電磁波感測器,因爲具有高指向性,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,因爲檢測部3 8係利用支 架4 1裝設於支柱,即使人接近刹某種程度,對測定的影響 也極少。此外,電磁波感測器,即使寬度〇.3mm程度之部 位,只要電磁波能到達即可進行位置檢測,此外,因爲不 是邊緣1點之檢測,也不是範圍之檢測,故幾乎不會發生 -14-S -13- 201221691 The detection portion 38 is fixedly disposed at the edge of the steel strip 1 and at a position far from the zinc tank 11, and can be reduced in the environment affected by the heat of the high-temperature steel strip 1 and the zinc dust. The position detection of the edge of the steel strip 1 is carried out. At the same time, electromagnetic waves (microwaves) are hardly affected by the temperature, pressure, flow rate, dust, and the like of the gas. Therefore, the electromagnetic wave sensor unit 32 used in the present embodiment is more resistant to heat, dust, and the like than the optical sensor in principle, and the influence of heat and dust received by the environment is set. 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 ±1. 〇mm . Further, the electromagnetic wave sensor unit 32, as described above, is basically free from maintenance due to the influence of temperature, dust, and the like. Even if 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. 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 of braking, 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 33mm. In addition, since it is not the detection of the edge 1 point, nor the detection of the range, it will hardly occur -14-

In addition, even when maintenance is required, as described above, it is easy to perform maintenance without stopping the work. 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 mounted along the frame member 4 When the linear guide of 0 is formed by movement, it becomes 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 4 is connected and separated from the body portion 37 side portion by the connector 46, by cutting away from the electromagnetic wave cable 39. The side portion of the main body portion 37 makes it easy to remove the frame member 40. Further, the position detection of the steel strip 1 is performed by using a relatively high-frequency first electromagnetic wave of, for example, 10 GHz which can be detected with high accuracy, and a second electromagnetic wave (carrier of a relatively low frequency of 2.5 GHz which can be stably detected, for example. When the electromagnetic waves of the two types 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. 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. In the unit -15-201221691, the detection unit is fixedly disposed at a position separated from the end portion in the width direction of the metal strip, and the metal can be detected without being affected by dust, heat, or the like from the molten metal.

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 detection unit 38 has two antennas that radiate electromagnetic waves of different frequency 'rates, respectively.
