であるとぎに特に有利である。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for detecting the position of the side edge of a web conveyed in a floating state by fully utilizing back pressure. Prior art] When transporting nine continuous long nibs of paper, cloth, film material, etc., the nine nibs are supported in a floating state by blowing air at the bending point of the transport path. First, a device called a reparser is used to change the direction of transport. The support for 9 nibs by this reparser is
This is particularly advantageous when the web is sensitive to damage, such as photographic film, because the surface of the nine nibs does not come into direct contact with the reparser.

傷されたり。However, as described above, when the web is supported and transported in a floating state, the web may be displaced from the designated transport path due to the imbalance of tension applied to the web or the influence of turbulence in the airflow of the atmosphere. Lateral displacement is likely to occur. When this lateral displacement occurs, the web may come into contact with a conveyance guide or the like and be damaged.

In order to prevent such accidents, it is necessary to immediately detect lateral deviations in the web and take appropriate measures to deal with the lateral deviations. Naturally, in order to detect the lateral deviation Vk of the web, it is sufficient to detect the position of the side edge of the web by fil''V'.

ブの側縁にキズが生じたり。Conventionally, there are many known methods for detecting the position of the side edge of a web by bringing all the sensing parts of the sensor into contact with the side edge of the web, but which one is the best? Even if the web is wet, scratches may occur on the side edges of the web due to contact with the sensing part.

全必要とするなどの欠点がわる。However, in the above method using sensor sound, the information obtained from a single sensor only depends on the installation of the sensor. Therefore, in order to detect the position of the side edge of the web or the amount of displacement, it is necessary to arrange a large number of sensors in a horizontal direction across the detection range. becomes. Moreover, if the web is photosensitive like photographic film, it is impossible to use a general sensor as a sensor.
-1゜-1, the method using the camera? In this case, the position of the side edge of the web is displayed on a screen, which has the disadvantage that more expensive processing equipment is required to obtain a signal representing the entire position of the side edge of the web.

In the second method for detecting the side edge position of a web according to the invention, in a device that suspends and carries the web using gas back pressure, the back pressure at a set position in the area where the side line of the web passes or in the vicinity of the vLM is measured. In light of the relationship between the displacement of the lateral position of the side edge of the web and the fluctuation of the back pressure at the set position, the position sound of the side edge of the web is detected from the magnitude of the measured back pressure. It is characterized by

Therefore, if the relationship between the measured value of the back pressure at the set position 8 and the position of the side edge of the web 7 is calculated in advance, the web 2 can be determined by comparing it with the calibration curve. From the measured value of the back pressure in the vicinity of the region L through which the side edge 2A passes, the order M'(r) of 2A can be determined on the web 2σ] side, and the calibration 11!i!

Since the pattern may differ depending on the conditions such as the curvature of the surface of the web, it is sufficient to carry out the measurement by conducting a test under the same conditions as the conveying state of the web. And do you want to store the contents of this calibration curve in the computer? Measured back pressure? By inputting it into the computer, it is possible to directly know the position of each edge of the web.

A digital manometer 11 (J) is provided to determine the total difference between back pressure measurements. According to such a method, while the web 2 is being conveyed through a predetermined fli transfer, the magnitude of the back pressure obtained at both pressure measurement ports 13, 13 becomes equal to each other, and the digital manometer For example, the display of 11 is 0, but when the pressure gauge 11 is displaced laterally, the back pressure at the foot opening 13 increases and the other decreases, so the difference is detected in an expanded state. It will be here. Therefore, similarly to the previously described embodiments, both pressure measurements were taken on day 13.
By using a calibration curve that shows the relationship between the difference value of 13 and the position of the side edge 2A of the web 2, the position of the side edge 2A of the web 2 can be detected with higher accuracy.
