発明の名称 帯伏連続体の継目検出装置 Title of the invention
技術分野 Technical field
本発明は布、 -紙、 皮等の帯伏連続体の継目を精度よ く検出す ることのできる帯状連続体の継目検出装置に関するものである < 背景技術  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seam detecting device for a band-shaped continuum that can accurately detect a seam of a band-shaped continuum such as cloth, paper, and leather.
一般に、 布等の帯伏体は所定の县さごとに継ぎ合わせ、 連続 体にしたものを加工する。 この継目は通常帯伏体が重なり合つ ているか、 或いは糸等によって厚く なつている。 したがって布 等の精鍊、 染色、 表面のスライ ス等の加工或いは測县に於いて は予め継目を検出する必要がある。  Generally, a band, such as a cloth, is joined at predetermined lengths and processed into a continuous body. This seam is usually made of overlapping folds or thickened by thread. Therefore, it is necessary to detect seams beforehand in the processing or measurement of refining, dyeing, surface slicing, etc. of cloth and the like.
ところで、 発明者はこのような継目を検出する好適な.装置と して、 特に応答性に勝れた検出を行え、 さ らに厚みが不均一な 帯伏連続体であつても継目の検出を一定感度で行える帯伏連続 体の継目検出装置 （実願昭 59 - 21973号） を既に提案した。  By the way, the inventor of the present invention is suitable for detecting such a seam. As a device, it is possible to perform detection with particularly excellent responsiveness, and to detect a seam even in a band-shaped continuous body having a non-uniform thickness. We have already proposed a seam detection device for continuity continuum (Japanese Utility Model Application No. 59-21973), which can perform the measurement with a constant sensitivity.
この装置は、 先端部に接触部を有する長寸の第 1 のアームと 短寸の第 2 のアームとを、 該接触部が帯状連続体の走行方向に 前後するようにその基部においてシャフ トに揺動自在に铀着し かつ第 2のアームが上動する際は同時に第 1 のアームも上動す るよう になし、 第 1 のアームは第 2 のアームに対しフ リ ー伏態 に上動するようにしている。 これにより、 帯伏連続体に厚みの 変化があっても、 第 2 のアームと共に第 1 のアームも上動する から両アームに相対的変位は生じず、 幅狭の継目が通り過ぎる 際にのみ第 1 のアームが第 2 のアームに対して相対的に変位し この変位を検出手段により検出して継目の検出を行うようにし ている。  In this device, a long first arm and a short second arm each having a contact portion at a distal end portion are shaft-shuffled at a base thereof so that the contact portion moves back and forth in the running direction of the belt-shaped continuous body. Attach so that it can swing freely, and when the second arm moves up, the first arm also moves up at the same time, and the first arm rises free with respect to the second arm. It works. As a result, even if the thickness of the continuum changes, the first arm moves up together with the second arm, so that there is no relative displacement between the two arms, and only when the narrow seam passes. The first arm is displaced relative to the second arm, and the displacement is detected by the detecting means to detect the joint.
このよう に両ァームの相対的な位置変化を検出するように構 成したことで、 蒂伏連続体が不均一な厚さであっても、 該厚さ 変化を吸収して継目のみを検出することが可能となった。 In this way, the configuration is such that the relative position change between the two arms is detected. As a result, even if the dynasty continuum has an uneven thickness, it becomes possible to detect the seam by absorbing the thickness change.
，しかし、 上述した継目検出装置には次の如き改良すべき問題 が残されている。  However, the above-described joint detection apparatus has the following problems to be improved.
つまり、 帯伏連続体における厚みの不均一がある程度の範囲 内であれば実用上の十分な応答性と感度を得るが、 その不均一 の度合が大き く なつたり、 或いは継ぎ合わせる各帯状体の厚み が大き く変化すると、 それが検出誤差となって表れる。 これは 2つのアームの基嬙が軸着され、 各遊端が前後に位置してァー ムの县さが異なることにより ·、 各遊嬙の変位が円弧軌跡となる ためである。 すなわち、 县寸の第 1 アームの接触部が短寸の第 2アームの接触部より も大きな円弧運動をすることから、 厚み の小さな継目の場合には継目が第 1 のアームの接触部に接触せ ず、 検出し得ない問題点があった。 したがつてまた、 設定した 厚みに対し帯状体の厚みがあまり大き く変化した場会にはその 都度各ァームの係合位置を設定し直す必要がある等の問題点が ある。  In other words, if the unevenness of the thickness of the band-shaped continuous body is within a certain range, practically sufficient response and sensitivity can be obtained, but the degree of the unevenness increases, or the band-like parts to be seamed together. When the thickness changes significantly, it appears as a detection error. This is because the bases of the two arms are pivotally mounted, the free ends are located in front and back, and the lengths of the arms are different. In other words, since the contact portion of the 县 -size first arm makes a larger circular motion than the contact portion of the short-size second arm, in the case of a seam having a small thickness, the seam contacts the contact portion of the first arm. However, there was a problem that could not be detected. Therefore, there are also problems such as the necessity of resetting the engagement position of each arm each time when the thickness of the belt-shaped body changes so much with respect to the set thickness.
発明の開示 Disclosure of the invention
そこで本発明は上記問題点を解消すベく なされたものであり その目的とするところは、 帯伏連続体における厚みが大き く変 化した場合にも何ら調整等を施すことなしに、 常に応答性に優 れ、 しかも一定感度で高精度の継目検出を行う ことができる帯 状連続体の継目検出装置を提供するにある。  Therefore, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to always provide a response without any adjustment even when the thickness of the band-shaped continuum changes greatly. An object of the present invention is to provide a seam detecting apparatus for a strip-shaped continuum, which is excellent in performance and capable of performing seam detection with high sensitivity and constant sensitivity.
また本発明の他の目的は、 帯状連続体に部分的な縦ジヮがあ つても誤検出することなく確実に継目を検出しう る帯状連続体 の継目検出装置を提供するにある。  Another object of the present invention is to provide a seam detecting device for a strip-shaped continuum that can reliably detect a seam without erroneous detection even if the strip-shaped continuity has a partial vertical groove.
本発明においては、 第 1 アームと第 2 アームの長さを略同一 としてその遊端位置を揄えている。 そして第 1 アームの遊端に 帯伏連続体への接触部を設け、 また第 2 アームの遊端には、 前 後に一対の接触部を備えた揺動部材を揺動自在に轴着している《 また第 1 アームの上動は第 2 アームに対してフ リ ーであるが、 第 2 アームが上動するときは第 1 アームも共に上動する。 In the present invention, the lengths of the first arm and the second arm are substantially the same. Ridiculed its free end position. The free end of the first arm is provided with a contact portion with the continuity band, and the free end of the second arm is swingably attached with a swing member having a pair of front and rear contact portions. <Also, the upward movement of the first arm is free with respect to the second arm, but when the second arm moves upward, the first arm also moves upward.
したがって、 先ず、 帯状連続体が走行し、 継目が第 2 アーム の後側の接触部を通過すると、 第 2 アームは帯伏連続体の表面 から離れる方向へ変位し、 これにより第 1 アームも第 2アーム に追従して変位する。 このため両アームの相対的な変位はない < 一方、 継目が第 1 アームの接触部を通過すると、 第 1 アーム は帯伏連続体の表面から離れ、 この場合の変位は第 1 アームの みである。 したがって、 両アーム間には相対的な変位が生じ、 この変位が検出手段で検出されることにより継目が検出される, さ らに、 帯状連続体が走行し、 継目が第 2 アームの前側の接 触部を通過すると、 第 2 アームは帯状連続体の表面から離れる 方向へ変位するが前記の場合と同様に第 1 アームと第 2 アーム の相対的な変位はない。  Therefore, first, when the band-shaped continuum runs and the seam passes through the contact portion on the rear side of the second arm, the second arm is displaced away from the surface of the band-shaped continuum, whereby the first arm is also displaced. Displaces following two arms. Therefore, there is no relative displacement between the two arms <On the other hand, when the seam passes through the contact part of the first arm, the first arm separates from the surface of the band-like continuum, and the displacement in this case is only the first arm is there. Therefore, a relative displacement occurs between the two arms, and the displacement is detected by the detecting means, so that the seam is detected. Further, the belt-shaped continuum runs, and the seam is located on the front side of the second arm. After passing through the contact portion, the second arm is displaced away from the surface of the belt-shaped continuum, but there is no relative displacement between the first arm and the second arm as in the case described above.
ところで、 帯伏連続体の厚みが大幅に変動した場合を想定す る。 この場合、 変動に伴い第 2 アームの各接触部は上昇 （又は 下降） するが揺動部材は上下に平行移動し、 かつ各アームの遊 端は略同一円弧上を変位する。 したがって両アームの遊端の相 対的位置は常に一致し、 厚みが大幅に変動しても検出精度、 検 出感度等は略一定となる。  By the way, it is assumed that the thickness of the continuum varies greatly. In this case, the contact portion of the second arm rises (or descends) with the fluctuation, but the swinging member moves up and down in parallel, and the free end of each arm displaces on substantially the same arc. Therefore, the relative positions of the free ends of both arms always coincide, and even if the thickness fluctuates significantly, the detection accuracy and detection sensitivity are almost constant.
本発明において好適には第 1 アームを第 2 アームの上に重ね る。 この場合揺動部材上面に透孔を設け、 この透孔から第 1 ァ 一ムの接触部を下方に位置させ、 帯状部材表面に接触可能とさ せる。 このように第 1 アームを第 2アーム上に重ねることによって 第 1 ァ -ムの接触部と第 2ァ一ムの両接触部とが帯状部材の走 行方向の一直線上に位置する。 したがって、 帯伏部材の表面に 帯伏部材の走行方向に伸びる縦ジヮが発生していても、 両ァ一 ムが該縦ジヮによって共に上動されるので両アームに相対的変 位が生じず、 縦ジヮを継目として誤検出することがない。 この 点両ァ一ムを並設すると、 縦ジヮによって第 1 ァ一ムのみが上 動されて両アームに相対的変位が生じて、 縦ジヮを誤って継目 として検出してしまう場合がある。 In the present invention, the first arm is preferably overlaid on the second arm. In this case, a through-hole is provided on the upper surface of the swinging member, and the contact portion of the first arm is positioned downward from the through-hole so that it can contact the surface of the belt-shaped member. In this way, by overlapping the first arm on the second arm, the contact portion of the first arm and both contact portions of the second arm are located on a straight line in the traveling direction of the belt-shaped member. Therefore, even if a vertical ridge extending in the running direction of the obi member is generated on the surface of the obi member, both arms are moved upward by the vertical ji, so that relative displacement between the two arms is caused. It does not occur and there is no erroneous detection as a vertical joint. If both arms are installed side by side, only the first arm is moved up by the vertical arm, causing a relative displacement between the two arms, and the vertical arm may be erroneously detected as a joint. is there.
なお橫ジヮは、 帯伏走行体が伸長状態で走行することによつ てほとんど発生することがない。  It should be noted that the page hardly occurs due to the running of the obicar in the extended state.

A notch 37a is provided below the locking lever 37 above the first arm 4 so that the first arm 4 can be displaced upward. On the other hand, a locking arch 39a straddling the locking lever 37 is fixed to the horizontal plate 23a, and an adjusting screw 39b is screwed to the upper end of the locking arch 39a. Then, when the arms 4 and 5 are on the surface P of the cloth W o without the seam T, that is, when they are on the same plane, the tip of the adjusting screw 39 b contacts the upper surface of the locking lever 37. As a result, when the second arm 5 is displaced away from the surface P of the cloth W o, the locking lever 37 is locked by the adjusting screw 39 b, and the L-arm 4 is also displaced to follow. Even when the arm 4 is displaced away from the surface P, only the first arm 4 is displaced by the notch 37a.

One of the springs 42 is locked to the first arm 4, the other is locked to the knob 43, and by rotating the knob 43, the type of cloth W o and the seam T The rotation torque is adjusted according to the state, generally, the type of the belt-shaped continuum W. Reference numeral 44 denotes a weight adjuster attached to the second arm 5. This weight adjuster 4 4 This is for adjusting the weight of the rollers 27, 33, and 34 to the cloth W o.

Can be detected. In addition, as such a detector 48, a detector that detects a change in capacitance, a detector that detects a change in light flux, a detector that detects a change in air pressure, and the like can be appropriately selected and used.
また、 側板 2 1 には表示ラ ンプ 5 1等を配設する表示パネル 5 2を設ける。  The side panel 21 is provided with a display panel 52 on which a display lamp 51 and the like are disposed.
次に以上の構成からなる継目検出装置 1 の動作機能について 説明する。  Next, the operation function of the joint detection device 1 having the above configuration will be described.
今、 布 W o が矢印 H方向へ一定の速度で走行している場合を 想定する。 各ローラ 2 7 、 3 3、 3 4 は布 W o の表面 P上に当 接しており、 各ローラ 2 7、 3 3、 3 4の外周面はそれぞれ前 記接触部 8 、 9、 1 2 となる。  Now, assume that the cloth W o is traveling at a constant speed in the direction of arrow H. The rollers 27, 33, and 34 are in contact with the surface P of the cloth Wo, and the outer peripheral surfaces of the rollers 27, 33, and 34 are in contact with the contact portions 8, 9, and 12, respectively. Become.
先ず、 継目 Tのない部分では各ローラ 2 7 、 3 3、 3 4 は同 一平面上にあり、 以て各アームの相対的変位はない。 そして、 継目 Tがローラ- 3 4を通過すると当該ローラ 3 は継目 Tの高 さだけ上方へ変位し、 これに伴い第 2アーム 5 も上方へ変位す るが、 この場合には前述のように第 1 アーム 4 も追従変位し両 アーム 4、 5 の相対的変位は生じない。 First, in the part without the seam T, the rollers 27, 33, and 34 are the same. There is no relative displacement of each arm on one plane. Then, when the seam T passes through the roller 34, the roller 3 is displaced upward by the height of the seam T, and accordingly, the second arm 5 is also displaced upward. In this case, as described above, The first arm 4 also displaces, and no relative displacement of the arms 4 and 5 occurs.
次いで、 継目 Tが口ーラ 2 7を通過した場合にはこれに伴い ローラ 2 7 は上方へ変位し、 以て第 1 アーム 4 も上方へ変位す る。 この際第 2アーム 5 は何ら変位せず、 したがって、 両ァー ム 4、 5間には相対的変位を生じる。 つまり、 このローラ 2 7 によつて継目 Tを検出できる。  Next, when the seam T passes through the mouth roller 27, the roller 27 is displaced upward accordingly, and the first arm 4 is also displaced upward. At this time, the second arm 5 is not displaced at all, so that a relative displacement occurs between the arms 4 and 5. That is, the roller 27 can detect the seam T.
さらに、 継目 Tがローラ 3 3を通過した場合には口ーラ 3 3 は上方へ変位するが前記ローラ 3 4の場合と同様に両アーム 4 5 の相対的変位は生じない。  Further, when the seam T passes through the roller 33, the mouth roller 33 is displaced upward, but no relative displacement of the arms 45 occurs as in the case of the roller 34.
ところで、 布 W o が走行し、 厚さの大幅に異なるものが送ら れてきた場合を想定する。  By the way, it is assumed that the cloth W o travels and a material having a significantly different thickness is sent.
この場合、 厚さの変化によって各ローラ 2 7、 3 3、 3 4 は 上方又は下方へ変位するが、 この場合、 特にローラ 3 3、 3 4 はリ ンク板 3 0 a、 3 0 aが第 2アーム 5 の遊端 7 に軸着して なるためそのまま平行移動する。 つまり、 遊端 7 の表面 Pに対 する高さはローラ 3 3、 3 の上下動変位によつては影響を受 けず一定である。 一方、 第 1 アーム 4 の遊端 6 と上記遊端 7 は 前後方向及び上下方向、 つまり これら各方向を含む面内で略一 致している。 したがって、 水平シャフ ト 2 2を中心に各アーム 4、 5が回転しても各遊端 6、 7 は同一円弧上を変位し、 この 結果、 布 W o において大幅な厚みの変動があつても各アーム 4 と 5 の相対的ずれを生ずることはない。  In this case, the rollers 27, 33, and 34 are displaced upward or downward due to the change in thickness.In this case, especially, the rollers 33 and 34 are linked by the link plates 30a and 30a. 2Because it is attached to the free end 7 of the arm 5, it moves in parallel. In other words, the height of the free end 7 with respect to the surface P is constant without being affected by the vertical displacement of the rollers 33,3. On the other hand, the free end 6 of the first arm 4 and the free end 7 are substantially coincident in the front-rear direction and the vertical direction, that is, in a plane including these directions. Therefore, even if the arms 4 and 5 rotate about the horizontal shaft 22, the free ends 6 and 7 are displaced on the same circular arc, and as a result, even if there is a large thickness variation in the cloth W o. There is no relative displacement between the arms 4 and 5.
以上、 実施例について説明したが、 本発明はこのような実施 例に限定されるものではない。 Although the embodiment has been described above, the present invention It is not limited to the example.
例えば、 布 W o が垂直伏態や傾斜伏態で走行する場合にも ト ルク調整器 4 1 や加重調整器 4 4を調整又は変更することによ つてローラ 2 7、 3 3、 3 が布 W o に所定の圧接力で接触す るようにすれば同様に実施できる。  For example, even when the cloth Wo runs in a vertical or inclined state, the rollers 27, 33, and 3 can be adjusted by changing or adjusting the torque adjuster 41 and the weight adjuster 44. The same can be achieved by contacting W o with a predetermined pressing force.
また、 接触部 8、 9、 1 2 としてローラの周面を利用した場 合を例示したが、 その他半円筒伏の曲面を単に接触させたり、 あるいはスキー伏のものを接触させてもよい。  Further, the case where the peripheral surfaces of the rollers are used as the contact portions 8, 9, and 12 has been exemplified. However, a curved surface having a semi-cylindrical shape may be simply contacted, or a surface having a ski shape may be contacted.
また、 ローラ 2 7、 3 3、 3 4のいずれか一つ又は複数にお ける回転数を検出するセ ンサを付設し、 帯状連続体の測县を行 えるようにしてもよい。 特に複数の口ーラの平均をとる等すれ ば正確な測县が行え、 各種制御等に利用できる。  Further, a sensor for detecting the number of rotations of any one or a plurality of the rollers 27, 33, and 34 may be provided to measure the continuous band. In particular, accurate measurement can be performed by averaging a plurality of mouthpieces, and this can be used for various controls.
その他、 細部の構成、 形伏、 数量、 配列等において本発明の 精神を逸脱しない範囲で任意に変更実施できる。  In addition, it is possible to arbitrarily change the configuration, details, shape, number, arrangement, and the like of the details without departing from the spirit of the present invention.

次に以上の構成からなる第 2実施例に係る継目検出装置 1 0 8 の動作機能について説明する。  Next, the operation function of the joint detection device 108 according to the second embodiment having the above configuration will be described.
今、 布 W o が矢印 H方向へ一定の速度で走行している場合を 想定する。 ローラ 1 2 2 、 接触部 1 3 0 、 1 3 2 は布 W。 の表 面 P上に当接している。  Now, assume that the cloth W o is traveling at a constant speed in the direction of arrow H. Roller 1 2 2, contact section 1 30, 1 32 are cloth W. Abuts on the surface P of.
まず、 継目 Tのない部分では口ーラ 1 2 2、 接触部 1 3 0 、 1 3 2 は布 W o に同一平面上で当接し、 両アーム 1 1 8 、 1 2 0 の相対的変位はない。 そして、 継目 Tが接触部 1 3 2を通過す ると接触部 1 3 2 は接触片 i 3 4がばね 1 3 8 によつて下方に 付勢されていることによってそのまま継目 Tの高さだけ上方へ 変位し、 これに伴い第 2 アーム 1 2 0 も上方へ変位するが、 こ の場合には前述のように第 1 アーム 1 1 8 も追従変位し、 両ァ ーム 1 1 8 、 1 2 0 の相対的変位は生じない。  First, in the part without the seam T, the mouth roller 122 and the contact parts 130 and 132 contact the cloth W o on the same plane, and the relative displacement of both arms 118 and 120 is Absent. Then, when the seam T passes through the contact portion 132, the contact portion 132 has only the height of the seam T because the contact piece i34 is urged downward by the spring 1338. The arm is displaced upward, and accordingly, the second arm 120 is also displaced upward. In this case, as described above, the first arm 118 is also displaced to follow, and both arms 118, 1 No relative displacement of 20 occurs.
次いで、 継目 Tがローラ 1 2 2を通過した場合にはこれに伴 いローラ 1 2 2 は上方へ変位し、 以て第 1 アーム 1 1 8 も上方 へ変位する。 しかしこの際第 2 アーム 1 2 0 は何ら変位せず、 したがって両アーム 1 1 8、 1 2 0間には相対的変位を生じる。 つまり、 このローラ 1 2 2 によって継目 Tを検出できる。  Next, when the seam T passes through the rollers 122, the rollers 122 are displaced upward, and the first arm 118 is also displaced upward. However, at this time, the second arm 120 is not displaced at all, so that a relative displacement occurs between the two arms 118 and 120. That is, the seam T can be detected by the rollers 122.
さ らに、 継目 Tが接触部 1 3 0を通過した場合には接触部 1 3 0 は上方へ変位するが前記接触部 1 3 2 の場合と同様に両アーム 1 1 8、 1 2 0 の相対的変位は生じない。 Furthermore, when the seam T passes through the contact portion 130, the contact portion 130 Is displaced upward, but no relative displacement occurs between the arms 1 18 and 120 as in the case of the contact portion 13 2.
次に、 布 Wo に縦ジヮ、 すなわち布 Wo にその走行方向に伸 びるシヮが発生-していても、 本実施例においては両アーム 1 1 8 1 2 0が重ね合わされた状態で設けられているので、 つまり、 ローラ 1 2 2 、 接触部 1 3 0、 1 3 2が布 Wo の走行方向の一 直線上に位置しているので、 縦ジヮの影響はローラ 1 2 2 、 接 触部 1 3 0、 1 3 2 に同一に作用し、 誤動作を招く ことな く継 目 Tを有効に検出しう る。  Next, even if the cloth Wo has a vertical gap, that is, a cloth extending in the running direction on the cloth Wo, in this embodiment, both arms 1 1 1 8 1 2 0 are provided in a superposed state. In other words, since the rollers 122 and the contact portions 130 and 132 are located in a straight line in the running direction of the cloth Wo, the effect of the vertical j The same action is applied to the contact portions 130 and 132, and the seam T can be effectively detected without causing a malfunction.
また、 布 Wo の走行速度が大なるとき、 継目 Tが接触部 1 3 2 に強く衝突して、 例えば接触片部 1 3 が水平板部 1 2 6 a と 一体の剛体であるときは上記の衝突のショ ックで両ァー Λ 1 1 8 Also, when the running speed of the cloth Wo is high, the seam T strongly collides with the contact part 13 2, for example, when the contact piece 13 is a rigid body integrated with the horizontal plate 1 26 a, Both で 1 1 8 in shock of collision
1 2 0が跳ね上げられ、 継目 Tが口ーラ 1 2 2に接触せず、 し たがって継目 Tが検出されないことが起こり う るが、 上記実施 例の場合には、 接触片部 1 3 4が水平板部 1 2 6 に回動自在に 設けられ、 かつばね付勢されているので、 上記のように継目 T が接触部 1 3 2 に強く衝突した際にはばね 1 3 8 の付勢力に抗 して接触片部 1 3 4が上動され、 第 2 アーム 1 2 0 自体はほと んど変位しない。 つまり上記の衝突のショ ックはばね 1 3 8 に よって吸収されてしまう。 したがって継目 Tはローラ 1 2 2を 押し上げ、 両アーム 1 1 8、 1 2 0 に相対的変位が生じ、 継目 Tが検出される。 Although the seam T may jump up and the seam T does not contact the mouthpiece 122, the seam T may not be detected, but in the case of the above embodiment, the contact piece portion 13 4 is rotatably provided on the horizontal plate portion 1 26 and is spring-biased. When the seam T collides strongly with the contact portion 13 2 as described above, the spring 13 8 is attached. The contact piece 134 is moved upward against the force, and the second arm 120 itself hardly displaces. In other words, the shock of the collision described above is absorbed by the spring 13. Therefore, the seam T pushes up the roller 122, causing a relative displacement between the two arms 118, 120, and the seam T is detected.
次に布 Wo が走行し、 厚さの大幅に異なるものが送られてき た場合を想定する。  Next, it is assumed that the cloth Wo travels and that a material with a significantly different thickness is sent.
この場合、 厚さの変化によってローラ 1 2 、 接触部 1 3 0、 In this case, depending on the change in thickness, the roller 12, the contact portion 130,
1 3 2 は上方または下方に変位するが、 この場合、 特に接触部 1 3 0、 1 3 2 は揺動部材 1 2 6が第 2ァームの遊端に軸着し てなるためそのまま平行移動する。 つまり、 遊嬙の表面 Pに対 する高さは接触部 1 3 0、 1 3 2 の上下動変位によっては影響 を受けず一定である。 一方、 第 1 アーム 1 1 8 の遊端と上記遊 端とは前後方向および上下方向、 つまり これら各方向を含む面 内で略一致している。 したがって、 水平シャフ ト 1 1 6を中心 に各アーム 1 1 8、 1 2 0が回耘しても各遊嬙は同一円弧上を 変位し、 この結果、 布 W o において大幅な厚みの変動があって も各アーム 1 1 8、 1 2 0 の相対的ずれを生ずることはない。 発明の効果 1 3 2 is displaced upward or downward.In this case, in particular, the contact portions 1 30 and 1 32 are pivotally attached to the free end of the second arm by the swinging member 1 26. Therefore, it translates as it is. That is, the height of the play with respect to the surface P is constant without being affected by the vertical displacement of the contact portions 130 and 132. On the other hand, the free end of the first arm 118 and the free end substantially coincide with each other in the front-rear direction and the vertical direction, that is, in a plane including these directions. Therefore, even if the arms 1 18 and 1 20 are cultivated around the horizontal shaft 1 16, each play is displaced on the same arc, and as a result, a large thickness variation occurs in the cloth W o. Even so, there is no relative displacement between the arms 118 and 120. The invention's effect
このように本発明に係る帯状連続体の継目検出装置によると きは、 帯伏連続体の厚みが犬から小、 または小から犬へ大幅に 変化するようなことがあっても何ら調整等することなしに常に そのままの伏態で継目の検出を行う ことができ、 しかもこのよ うな伏態であっても検出誤差のない高精度の検出と、 応答性に 勝れ、 一定感度での検出を行う ことができる。 よって、 著しい 作業性の改善と検出能力の向上を図ることができる。  As described above, according to the seam detecting apparatus for a belt-shaped continuum according to the present invention, even if the thickness of the band-shaped continuum greatly changes from dog to small, or from small to dog, any adjustment is performed. The seam can always be detected in the flat state without any trouble, and even in such a flat state, high-precision detection with no detection error, excellent responsiveness, and detection with a constant sensitivity It can be carried out. Therefore, remarkable improvement in workability and improvement in detection capability can be achieved.
また特に、 両アームが軸線を略一致して重ねて設けることよ り、 第 1 アームの接触部が揺動部材に設けた透孔から下方に臨 んで、 3つの接触部は帯状連続体の走行方向に一直線上に位置 しているので、 帯伏連続体に縦ジヮが発生し.ても継目を誤検出 することがない。  In particular, since the two arms are overlapped with their axes substantially coincident with each other, the contact portion of the first arm faces downward from the through hole provided in the swinging member, and the three contact portions move along the belt-like continuous body. Since they are located on a straight line in the direction, even if vertical ridges occur in the continuity of the band, no seam is erroneously detected.
