The oiling method is generally a continuous oiling method using an electrostatic oiling device. However, for example, when the amount of the rust preventive oil is insufficient or uneven oil coating occurs, the rust preventive effect is lowered, and conversely, in the case of overcoating oil, the basic unit of the rust preventive oil is increased, which is disadvantageous. At the same time, problems such as slippage in the next process and poor degreasing in lines that require degreasing may occur.Recently, the type of rust preventive oil and the amount of coating have been specified, and strict coating in the manufacturing process has been specified. Oil quantity management is required.

In a method of measuring the amount of oil applied to the surface of the metal material from the spectral distribution of the reflected light including the fluorescence generated by the irradiation, the reflected light including the fluorescence from the surface of the metal material is collected,
The collected light is separated into an excitation wavelength component and a fluorescence wavelength component, and the excitation wavelength intensity and the fluorescence wavelength intensity are measured from the separated excitation wavelength component and the fluorescence wavelength component, respectively. There has been proposed a method for measuring the amount of oil applied to calculate the amount of oil applied from the efficiency and the above-described excitation wavelength intensity and fluorescence wavelength intensity.

により油が蒸発している可能性が考えられる。Although it has been confirmed that sufficient sensitivity can be obtained by the method disclosed in Japanese Patent Application Laid-Open No. 63-61146, the method depends on the surface properties such as surface roughness and gloss, which vary from coil to coil and change with time. There is a drawback that a change in the light reflection characteristic is not taken into account and a measurement error occurs. In the method proposed in Japanese Patent Application Laid-Open No. 7-243970, although the above problem can be solved, it is a disadvantage common to all the above-mentioned conventional techniques, but when the moving speed of the object to be measured is different. There is a problem that a measurement error occurs. Therefore, the present inventors have investigated the phenomenon that causes a measurement error due to the change in the moving speed of the object to be measured, and as a result, when the object to be measured with a constant oiling is stopped as an extreme case, It was found that the fluorescence output when the object to be measured was continuously irradiated with the specific wavelength excitation light was attenuated with the peak at the moment of irradiation.
Therefore, in the method of measuring the average of the fluorescence output for a certain period of time in order to obtain the required sensitivity, which is usually performed, the measurement time includes an error due to the attenuation of the fluorescence output. Even when the device under test is moving, the time during which the device under test moves within the area where the excitation light is being radiated is continuously irradiated. Will change and an error will occur. The reason why the fluorescence output is attenuated when the excitation light is continuously irradiated is not clearly understood, but for example, it is possible that the oil is evaporated by the irradiation.

記(1) 式で表される。Next, the operation in the case where the oil amount is measured by using the oil amount measuring apparatus of the present invention thus configured will be described below. Now, while the metal material 1 having a predetermined amount d (μm) of the oil 2 applied to the surface and the oil amount measurement sensor 6 are operating at a relative speed V, the oil amount measurement sensor 6 transfers the metal material 1 to the metal material 1. On the other hand, when a certain excitation light is irradiated at a constant intensity, the fluorescence intensity changes with time as shown in FIG. At this time, the measurement start time t 0 by the oil amount measurement sensor 6 is used.
Assuming that the fluorescence intensity detected at is α (0), the oil coating amount d is expressed by the following equation (1).

A conventionally known relational expression or calibration curve may be used.
However, the fluorescence intensity attenuates along the curve of α (t) as the measurement time elapses. Therefore, the average intensity α mean detected when measuring only the time T S is represented by the following equation (2). .

との関係を示すものである。D = f (α mean · C (V)) (4) The measurement time T S is the relative speed V (m / min) and the excitation light irradiation length in the direction of the relative speed. L (m) is represented by the following equation (5). T S = L / V (5) Actually, it is difficult to actually measure the values of α (0) and α (t), and it is also difficult to obtain L with exact values. , V, etc. were measured under various conditions to measure the amount of oil applied by the fluorescence intensity,
It is a practical means to obtain a correction coefficient C (V) by comparing the result with the result of a method of measuring weight using a precision balance or the like. FIG. 3 shows an example of C (V) obtained in such a manner. The metal material 1 coated with a certain amount of oil 2 is moved at various speeds, and the fluorescence output when the excitation light is irradiated at a certain speed is shown in FIG. It shows the relationship with the relative speed.

確保ができなくなる。In contrast to the above equation (1), in the equation (4), the correction coefficient C (V) is changed according to the relative speed V between the metal material 1 and the oil amount measurement sensor 6, so that the relative speed V is slow. Even when the fluorescence intensity is attenuated, it is possible to accurately measure the amount of applied oil by about 1/2 to 1/5. The relative velocity V is preferably in the range of 0.1 to 800 m / min. In addition, 800m / m
When the value exceeds in, C (V) becomes substantially 1 and the effect of the present invention is hardly obtained. On the other hand, V is 0.1 m / mi
If it is less than n, it is not possible to secure the correction accuracy unless the speed is controlled with high accuracy.

For example, the reflected light including the fluorescence described in Japanese Patent Application Laid-Open No. 7-243970 is cited. It goes without saying that the present invention also relates to the present invention in that the amount of oil applied is measured using the fluorescence output. Further, in the above-described embodiment, the case where the measurement is performed on the continuous line output side is illustrated. However, even if the metal material 1 is a small sample, the sample is applied to the oil amount measurement sensor 6.

The sensor for measuring the amount of applied oil used at this time is based on the principle of the laser-induced fluorescence method.

The following effects are obtained. For the operating metal material to be measured, when converting the measured values of the fluorescence intensity, reflected light intensity, etc. to the amount of oil applied,
Since the operation speed of the metal material is corrected as a parameter, accurate measurement of the amount of applied oil can be performed regardless of the operation speed of the metal material. For the stopped metal material, operate the oiling amount measuring device side to minimize the attenuation of the fluorescence intensity, and correct it by the operating speed of the oiling amount measuring device in the same manner as above. Therefore, even when the metal material is stopped, it is possible to accurately measure the amount of applied oil without depending on the attenuation of the fluorescence intensity. Also, in this case, when measuring the sample, not only one point but also the average value of the operating range of the oiling amount measuring device is measured, so even if the oiling state is not uniform, the average oiling amount is measured. Measurement is possible.
