In contact with a certain upper edge portion, the traveling direction of the linear body 1 is changed to the upper edge portion side, and the linear body 1 is guided into the groove portion 31 of the rotating frame 3.
第二ガイド７は、上記支持フレーム１に回転可能に軸設された鍔付きガイドローラ７１から成り、上記第一ガイド６により案内されて回動フレーム３の溝部３１内を通過した線状体１の他方の側縁部である下縁部と接触して、線状体１の走行方向を下縁部側へ変更する。 The second guide 7 is composed of a guide roller 71 with a flange rotatably mounted on the support frame 1, and is a linear body 1 guided by the first guide 6 and passed through the groove 31 of the rotating frame 3. The traveling direction of the linear body 1 is changed to the lower edge portion side in contact with the lower edge portion which is the other side edge portion of the above.
これら第一ガイド６及び第二ガイド７は、図４に示すように、半径ｄ３で同径であり、回動フレーム３の回動軸心Ａ２を挟んで正反対かつ等距離ｄ４の位置に配設されている。本実施形態では、これらガイドローラ６１・７１の軸心Ａ３が回動フレーム３の回動軸心Ａ２と平行になるように配設されている。 As shown in FIG. 4, the first guide 6 and the second guide 7 have the same diameter with a radius d3, and are arranged at positions opposite to each other and equidistant d4 with the rotation axis A2 of the rotation frame 3 interposed therebetween. Has been done. In the present embodiment, the axis A3 of the guide rollers 61 and 71 is arranged so as to be parallel to the rotation axis A2 of the rotation frame 3.
このように本実施形態の線状体の欠点検出装置１０は、線状体１の一方の側縁部側（上縁部側）の欠点部を検出する第一検出部４と、線状体１の他方の側縁部側（下縁部側）の欠点部を検出する第二検出部５とが、線状体１の中心線Ａ１と交差する回動軸心Ａ２を挟んで正反対かつ等距離ｄ１の位置に配設されているので、図５に示すように、回動フレーム３を支持フレーム２に対し回動軸心Ａ２周りに所要角度θ、回動させる操作を行うだけで、線状体１の一方の側縁部（上縁部）に対する第一検出部４の検出領域４３の離間距離ｄ２と、線状体１の他方の側縁部（下縁部）に対する第二検出部５の検出領域５３の離間距離ｄ２とを、同一距離を保ちながら同時に調整することができる。したがって、欠点部の長さに応じた線状体の欠点検出作業を大幅に容易化することができる。 As described above, the defect detection device 10 for the linear body of the present embodiment has the first detection unit 4 for detecting the defect on one side edge side (upper edge side) of the linear body 1 and the linear body. The second detection unit 5 for detecting the defect portion on the other side edge portion side (lower edge portion side) of 1 is opposite and equidistant with the rotation axis A2 intersecting the center line A1 of the linear body 1. Since it is arranged at the position of the distance d1, as shown in FIG. 5, a line can be obtained simply by rotating the rotating frame 3 with respect to the support frame 2 at a required angle θ around the rotation axis A2. The distance d2 of the detection region 43 of the first detection unit 4 with respect to one side edge portion (upper edge portion) of the striatum 1 and the second detection unit with respect to the other side edge portion (lower edge portion) of the linear body 1. The separation distance d2 of the detection region 53 of 5 can be adjusted at the same time while maintaining the same distance. Therefore, it is possible to greatly facilitate the work of detecting defects in the linear body according to the length of the defect portion.
さらに、本実施形態の線状体の欠点検出装置１０は、線状体１の一方の側縁部（上縁部）と接触して線状体１の走行方向を一方の側縁部側（上縁部側）へ変更する第一ガイド６と、線状体１の他方の側縁部（下縁部）と接触して線状体１の走行方向を他方の側縁部側（下縁部側）へ変更する第二ガイド７とが、同径ｄ３であり、そして、回動軸心Ａ２を挟んで正反対かつ等距離ｄ４の位置に配設されているので、欠点検出すべき線状体１を第一ガイド６に下掛けし、第二ガイド７に上掛けする操作を行うだけで、線状体１の中心線Ａ１と回動フレーム３の回動軸心Ａ２とを交差させることができ、あらためて軸心合わせ作業等を行う必要がない。しかも、たとえ線状体１の太さが変わったとしても、その中心線Ａ１と回動軸心Ａ２とは必ず交差することになるので、例えば糸替え時においても、軸心合わせ作業等を行う必要がなく、この点においても、線状体の欠点検出作業を大幅に容易化することができる。 Further, the defect detecting device 10 for the linear body of the present embodiment comes into contact with one side edge portion (upper edge portion) of the linear body 1 and sets the traveling direction of the linear body 1 on the one side edge portion side (upper edge portion). The first guide 6 that changes to the upper edge side) comes into contact with the other side edge portion (lower edge portion) of the linear body 1 and the traveling direction of the linear body 1 is changed to the other side edge portion side (lower edge portion). Since the second guide 7 to be changed to the part side) has the same diameter d3 and is arranged at the position opposite to the rotation axis A2 and at the same distance d4, the defect should be detected. The center line A1 of the linear body 1 and the rotation axis A2 of the rotation frame 3 are crossed by simply suspending the body 1 on the first guide 6 and suspending the body 1 on the second guide 7. There is no need to perform axis alignment work again. Moreover, even if the thickness of the linear body 1 changes, the center line A1 and the rotation axis A2 always intersect with each other. Therefore, for example, even when changing threads, the axis alignment work or the like is performed. It is not necessary, and in this respect as well, the work of detecting defects in the linear body can be greatly facilitated.
以上、本実施形態の線状体の欠点検出装置１０について説明したが、本発明は他の実施形態でも実施することができる。例えば、図６に示す、線状体の欠点検出装置２０のように、第一ガイド６及び第二ガイド７を円柱形状のガイドロッド６２・７２で構成してもよい。これらガイドロッド６２・７２が同径であり、回動軸心Ａ２を挟んで正反対かつ等距離の位置に配設されていればよい。 Although the defect detection device 10 for the linear body of the present embodiment has been described above, the present invention can also be implemented in other embodiments.

These guide rods 62 and 72 may have the same diameter and may be arranged at positions opposite to each other and equidistant with respect to the rotation axis A2.
また、図６に示すように、回動フレーム３の回動軸心Ａ２は、線状体１の中心線Ａ１と必ずしも直交していなくてもよく、斜めに交差していてもよい。この場合であっても、回動フレーム３を回動軸心Ａ２周りに適宜、回動させることにより第一検出部４及び第二検出部５の各検出領域４３・５３の線状体１に対する離間距離を同時に調整することができる。 Further, as shown in FIG. 6, the rotation axis A2 of the rotation frame 3 does not necessarily have to be orthogonal to the center line A1 of the linear body 1, and may intersect diagonally. Even in this case, the rotation frame 3 is appropriately rotated around the rotation axis A2 with respect to the linear body 1 of the detection regions 43 and 53 of the first detection unit 4 and the second detection unit 5. The separation distance can be adjusted at the same time.
また、上記実施形態では、第一検出部４によって線状体１の一方の側縁部側となる上縁部側の欠点部を検出し、第二検出部５によって線状体１の他方の側縁部側となる下縁部側の欠点部を検出しているが、本発明は勿論これに限定されるものではなく、例えば、第一検出部４によって線状体１の一方の側縁部側となる正面部側の欠点部を検出し、第二検出部５によって線状体１の他方の側縁部側となる背面部側の欠点部を検出するようにしてもよい。また、一本の線状体１に対し、中心線Ａ１周りの検出領域の方向を互いに異ならせた複数対の第一検出部４及び第二検出部５を配設するようにしてもよい。 Further, in the above embodiment, the first detection unit 4 detects a defect portion on the upper edge portion side which is one side edge portion side of the linear body 1, and the second detection unit 5 detects the other defect portion of the linear body 1. Although the defect portion on the lower edge portion side, which is the side edge portion side, is detected, the present invention is not limited to this, of course. For example, the first detection portion 4 detects one side edge of the linear body 1. The defect portion on the front surface portion side, which is the portion side, may be detected, and the defect portion on the back surface portion side, which is the other side edge portion side of the linear body 1, may be detected by the second detection unit 5. Further, a plurality of pairs of first detection unit 4 and second detection unit 5 may be arranged on one linear body 1 in which the directions of the detection regions around the center line A1 are different from each other.
