There was something that looked like a story. When winding a rolled material into a coil shape in the first winding device, this type of device may cause unevenness on the end face of the coil due to meandering of the strut 11 (as shown in Fig. 5), or the coiler shaft. Due to poor parallelism, etc., the end face becomes slanted as shown in Figure (b), making handling in the next process difficult.
Edge 1) There were problems such as a decrease in yield due to an increase in the amount of mink.

修正していた。In order to measure the irregularity of the coil winding shape, that is, the coil end face, the distance to the coil end can be economically measured using laser distance measurement on the coil conveyor line, which is the downstream process of the winding device. The degree of irregularity of the coil end face is determined from the obtained data. Based on this determined pattern, the points that require adjustment in the winding device are determined based on experience and intuition, and the winding shape Y from the next winding coil is determined based on this determination.
It was being corrected.

Therefore, the edge position measuring device is required to be constructed so as to be able to accurately and continuously measure the edge position of the outermost circumference of the coil during one winding without delay in detection.

出することが可能となる。Next, an example of detecting the outermost circumferential position of a coil that becomes thicker during winding will be explained with reference to FIG.
As shown in Fig. al, the edge position measuring device [(31Y% near the outermost circumferential position of the coil, the coil (moves back and forth a minute distance in the winding thickening direction of 21 (direction a or b in the figure)) is constantly equipped with a scanning cable. Here, while the edge position detection device (3) scans the outermost periphery of the coil end face, it outputs a signal corresponding to the distance t from the coil end face, but when it deviates from the outermost position of the coil, A signal corresponding to a distance value outside the preset range is output, and both signals change on and off, so by detecting this change, the outermost circumference position of the coil can be detected. The edge position at the outermost circumferential position of the coil can be detected using the value immediately before the change in the measured value by the edge position measuring device (3).

減少するように構成される。In addition, in the IJ2 diagram (shown in BL), when the edge position measuring device (3) is constantly rotated back and forth at a minute angle to perform rotational scanning, an on-off change appears in its measurement output. Therefore, by detecting this change, it is possible to similarly detect the edge position at the outermost circumferential position of the coil. Furthermore, these scanning progresses are as follows:
The center point will be the outermost circumference position of the detected coil5.
It is configured to move sequentially according to the thickness of the roll to reduce the invalid measurement time.
