厚が測定されるようになされている。As shown in FIGS. 1 and 2, the rolled aluminum foil (A) rolled by the working roll (2) of the rolling mill (1) is guided to the delivery side guide rolls (3) and (3) and wound. The foil is wound around the take-up reel (4), and the foil thickness is measured between the working roll (2) and the guide roll (3).

る。Between the working roll (2) and the delivery side guide roll (3), the foil thickness measuring unit (b) of the foil thickness measuring device (B) is arranged such that the rolled foil (A) is vertically separated. The upper arm measurement part (b1) and the lower arm measurement part (b2) are provided with an X-ray emission port and an entrance port, and a purging air injection port (5) (5), respectively, at corresponding positions on the upper arm measurement part (b1). Has been.

る。Then, X-rays are radiated from the radiation port of the foil thickness measuring unit (b) to the measurement site of the rolled foil (A) immediately after rolling, which is rolled by the working roll (2), and are incident on the incidence port. By doing so, the foil thickness of the rolled foil (A) is continuously measured. In this measurement, the X-ray emission port,
If a scale such as a foreign substance adheres to the entrance and the measured part of the measured rolled foil (A), a measurement error will occur. Therefore, the purging air (C) is jetted from the upper and lower purging air jet ports (5) and (5) of the measuring section (b) toward the measurement site.

るだけそれに近い値に設定することが望ましい。The above-mentioned structure is the same as that of the conventional foil thickness measuring apparatus, but in this embodiment, the air is preheated when the purging air (C) is jetted. The reason for heating in this way is as follows. That is, when air at room temperature is used as the purging air (C) as in the prior art, the temperature of the purging air (C) is relatively lower than the temperature of the rolled foil (A) immediately after rolling, As the rolled foil (A) is locally cooled and contracted locally, local wrinkles (a) are generated at the measurement site of the rolled foil (A) as shown by the broken line in FIG. Because it does. For the above reason, the purging air (C) is
It is desirable to set the same temperature as that of the portion to be measured of the rolled foil (A) or a value as close as possible to the temperature.

Guided to (5), steam pipes (heating means) (9) and (10) are installed along a part of the pipes (7) and (8), so that the inside of the air supply pipes (7) and (8). The air passing through is indirectly heated. Opening and closing solenoid valves (11) (12) are installed on the inlet sides of the steam pipes (9) (10) to adjust the temperature of the air.
Temperature sensors (13, 14) for measuring the air temperature after heating are attached to the air supply pipes (7, 8) so that the purging air (C) can be adjusted to a predetermined temperature. In the figure, (15) is a heat insulating material.

に、不良品の発生をなくすことができる。EFFECTS OF THE INVENTION The foil thickness measuring device according to the present invention is a non-contact type that utilizes radiation such as X-rays and β-rays, so that contact scratches on the rolled foil are measured along with the measurement of the metal foil to be measured. Not only there is no risk of attaching, but means for heating the purging air is provided, and the air heated by the means is adapted to be jetted toward the measurement site of the rolling foil, so that it is immediately after rolling. It is possible to eliminate or reduce the difference between the temperature of the rolled foil and the temperature of the purging air sprayed onto the measured portion. For this reason, local cooling of the rolled foil and local thermal shrinkage caused by it are eliminated, and it is possible to avoid the inconvenience that wrinkles are generated in the measured metal rolled foil. Therefore, it is possible to save the troublesome work of finely adjusting the winding tension to extend the wrinkles, improve the production efficiency, and eliminate defective products.
