行なっていた。2. Description of the Related Art A profile which does not have a symmetric cross-sectional shape, such as a round bar, is apt to bend due to its asymmetry during rolling or subsequent cooling. For this reason, the standards for shape members often specify allowable values for bending. For example, in the case of hot-rolled stainless steel angle steel (equal angle steel), JIS-G4317 specifies that bending is 3 mm or less per 1 m in length (total length is In the case of xm, it is defined as 3 × xmm or less). Conventionally, this bending has been measured by a method in which a thread is stretched between both ends of the angle member and the distance from the thread is measured.

る。[Function] Rolling of long shaped material (or subsequent cooling, straightening, etc.)
In general, the bending direction due to does not always coincide with the lateral direction when the long shape member is naturally placed on the floor (flat surface). This is because the profile has a peculiar cross-sectional shape, and when it is naturally placed on the floor surface, it tends to take a certain posture depending on the cross-sectional shape. In this case, the bend is restrained by the floor surface, and the accurate bend cannot be measured. On the other hand, when it is not placed on a flat surface but is simply supported at two points at both ends, an oblique downward bending occurs due to the original bending of the long shaped material and a downward deflection due to the weight of the long shaped material. Therefore, in order to detect the original bending of the long shaped member from the bending thus synthesized, only the bending in the direction perpendicular to the direction of the bending is measured. However, since this is only the one-way component of the original bending of the long shaped material, measurement is performed in two different directions, and the original bending of the long shaped material is calculated based on this. The bend calculating means d detects a bend based on the position data of the long shaped material detected by the position detectors c at each position before and after the posture changing means b changes the posture of the long shaped material, and calculates the bending. Based on this, calculate the original bending of the long section.

置き替えることができるようになっている。EXAMPLE An example in which the present invention is applied to the bending measurement of an angle material (equal-sided mountain shape material) will be described. As shown in FIG. 1, the automatic bending measuring apparatus used in this embodiment has two support bases 11 and 12 (FIG. 1A) for supporting the angle member 10 and one support base 11 and one support base 12 respectively. Sets and three sets of distance sensor sets 13 (13a, 13b, 13c, 1 provided between them)
3d, 13e), and a controller 14 that receives data from the total distance sensor 13 and calculates the bending of the angle member 10 (FIG. 1 (b)). Each support 11,
As shown in FIG. 3, by rotating the rotating arm 20, the angle member 10 is changed into the “F” shape (a) and the “C” shape rotated by 90 degrees (b). It can be replaced.

ある。Here, the angle member 10 is not placed in the “Γ” shape, as shown in FIG. 4, when the angle member 10 is placed in the “Γ” shape, the deflection of the angle member 10 is restrained by the table 24. This is because it will come out in an obliquely downward direction (arrow 25).

As shown in (a) and (b), two distance sensors 131,
The position detector is composed of 132 units. Here, the reason why two distance sensors are used for one location is that the distance sensor 13 used here is used.
This is because there is a constraint that 1 and 132 must be measured from a direction perpendicular to the surface to be measured, and when using a distance sensor without such a constraint, Only one distance sensor needs to be provided. In the present embodiment, since the right angle member 10 is targeted, both distance sensors 131 and 132 are connected to the distance measuring line 2 thereof.
1 and 22 are orthogonal to the angle member 10 as the DUT 1
It is set to incline upward from the horizontal direction by 45 degrees in one plane. As described above, the distance sensors 131 and 13
2 needs to be arranged so as to measure the distance from the direction perpendicular to the side, and therefore the installation angle of both distance sensors 131, 132 is set to that for an angle member whose both sides make an angle other than 90 °. Need to be changed accordingly. Further, as the distance sensors 131 and 132, a laser distance sensor,
An ultrasonic distance sensor or the like can be used.

The bending of the angle member 10 is measured according to the program loaded in M (or stored in ROM in advance).

First, in response to a timing signal from the control device 14, a moving device (not shown) mounts the angle member 10 that has completed the straightening process, which is the previous process, on both support bases 11 and 12.
Put it in the shape of "he" on top. Here, since the thickness of the portions of the supporting bases 11 and 12 that support the angle member 10 is much shorter than the entire length of the angle member 10, the angle member 10 has a thickness of about 2 mm.
It is in a point support state.

Then, the horizontal component Dx of the bending of the angle member 10 in this posture is calculated based on the data of (h, Peh).

It is also possible to determine the maximum value of the distance from the reference line 23 as the horizontal component Dx of the bend.

After calculating x and Dy, the bend is determined based on them. Various methods can be considered for the determination here, but in the simplest case, the horizontal components Dx and Dy in both postures are each given a predetermined bending allowable range (for example, JIS-G43 described above).
17, the distance xm between the distance sensors at both ends may be 3 × x mm or less), and if any one of them is deviated, it may be determined as a failure (this is The maximum value of the components Dx and Dy is the bending Dm of the angle member 10, and this bending Dm is the same as the method of comparing with the allowable range). Also, the component D in two directions at each measurement point
It is also possible to combine x and Dy to calculate the curve Dm, and compare this with a predetermined allowable range. In addition,
If the measured bending of the angle material is out of the specified range, take measures such as changing the setting of the straightener.
