Description

画像処理装置Image processing device
　本発明は、主として、空気入りタイヤの製造において、ビードの外周にエーペックスが貼付けられたエーペックス付ビードの検査を行うための画像処理装置に関する。 The present invention mainly relates to an image processing apparatus for inspecting a bead with an apex in which an apex is attached to the outer periphery of the bead in the manufacture of a pneumatic tire.
　空気入りタイヤの製造においては、タイヤの構成部材であるリング状のビードの外周にエーペックスを貼付けるエーペックス貼付工程が採用されている。 In the manufacture of pneumatic tires, an apex pasting process is employed in which an apex is pasted on the outer periphery of a ring-shaped bead that is a constituent member of the tire.
　このエーペックス貼付工程においては、フォーマーを備えたビードエーペックスジョイント装置およびビード投入装置が使用され、ビードをビード投入装置からフォーマーに受け渡し、このフォーマーにおいてビードの外周にエーペックスを巻き付け、エーペックスの先端部と後端部とを接合してエーペックス付ビードを形成する（例えば、特許文献１）。 In this apex pasting process, a bead apex joint device and a bead loading device equipped with a former are used. An end part is joined and an apex bead is formed (for example, patent documents 1).
　そして、エーペックス付ビードは、エーペックスの接合部が検査された後、ストック装置に向けてフォーマーから蹴り出される。 Then, the bead with apex is kicked out of the former toward the stock device after the joint of the apex is inspected.
　かかる工程において、エーペックスの接合部を検査する場合、画像処理装置を採用し、画像処理装置のカメラをエーペックスの接合部の垂直方向（正面）に設置して検査することが考えられる。 In this process, when inspecting the apex joint, it is conceivable to employ an image processing apparatus and inspect the image processing apparatus by installing it in the vertical direction (front) of the apex joint.
　しかし、ビードエーペックスジョイント装置は、フォーマーの周辺に種々の機構が備わっているため、エーペックスの接合部の垂直方向にカメラを設置するためのスペースを確保することができない。しかし、エーペックスの接合部の垂直方向から外れた位置にカメラを設置した場合、接合部を正確に検査することができない。 However, since the bead apex joint device has various mechanisms around the former, it is not possible to secure a space for installing the camera in the vertical direction of the apex joint. However, when the camera is installed at a position deviated from the vertical direction of the apex joint, the joint cannot be accurately inspected.
　そこで、従来は、目視によりエーペックスの接合部の検査を行っていたが、作業者による検査負担が大きく、また、タイヤの品質向上のため、目視検査よりも高い検査精度が求められていた。 Therefore, in the past, inspection of apex joints was performed visually, but the inspection burden on the operator was large, and higher inspection accuracy was required than visual inspection in order to improve tire quality.

１．画像処理装置
　画像処理装置の説明の便宜上、まず、画像処理装置が配置されるビードエーペックスジョイント装置Ａについて説明する。 1. Image Processing Device For convenience of description of the image processing device, first, the bead apex joint device A in which the image processing device is arranged will be described.
（１）ビードエーペックスジョイント装置の構成
　図２に示すように、ビードエーペックスジョイント装置Ａは、ビードＡ１を保持して回転させるフォーマーＡ２と、圧着ローラＡ３と、エーペックスＡ４をビードＡ１まで搬送する図外の搬送機構とを備えており、ビードＡ１を、図外のビード投入装置からフォーマーＡ２に受け渡し、フォーマーＡ２においてビードＡ１の外周にエーペックスＡ４を巻き付け、圧着ローラＡ３によりエーペックスＡ４の先端部と後端部とを接合してエーペックス付ビードを形成する。 (1) Configuration of the bead apex joint device As shown in FIG. 2, the bead apex joint device A is not shown to convey the former A2 that holds and rotates the bead A1, the pressure roller A3, and the apex A4 to the bead A1. The bead A1 is transferred from the bead loading device (not shown) to the former A2, the apex A4 is wound around the outer periphery of the bead A1 in the former A2, and the front end and the rear end of the apex A4 are pressed by the pressure roller A3. The bead with apex is formed by joining the parts.
（２）画像処理装置の構成
　画像処理装置は、ビードエーペックスジョイント装置Ａに配置されるものであって、画像センサーＢと、ミラー１６と、照射（発光）面が平板状のＬＥＤ照明等の照明器具１７、アクチュエータ（伸縮機構）１８とを備えている（図１、図２参照）。 (2) Configuration of the image processing apparatus The image processing apparatus is arranged in the bead apex joint apparatus A, and includes an image sensor B, a mirror 16, and an illumination such as LED illumination having a flat (illuminated) surface. An instrument 17 and an actuator (extension mechanism) 18 are provided (see FIGS. 1 and 2).
　図１に示すように、画像センサーＢは、カメラ１１、解析プログラムを内蔵したコントローラ１２、コンソール１３、ＤＣ２４Ｖ電源１４およびモニタ１５を備えている。 As shown in FIG. 1, the image sensor B includes a camera 11, a controller 12 with a built-in analysis program, a console 13, a DC 24V power supply 14, and a monitor 15.
　画像処理装置のアクチュエータ１８の本体部分およびカメラ１１は、配置スペースとの関係からビードエーペックスジョイント装置ＡのフォーマーＡ２の外側に配置されている。 The main body portion of the actuator 18 of the image processing apparatus and the camera 11 are arranged outside the former A2 of the bead apex joint apparatus A because of the arrangement space.
　図３に示すように、ミラー１６は、エーペックスＡ４の接合部Ｊ（図４参照）とカメラ１１との間に配置して、カメラ１１の光軸に対して４５°傾斜して配置されることにより、ミラー１６に映ったエーペックスＡ４の接合部Ｊの鏡像をカメラ１１が撮像できるようになっている。 As shown in FIG. 3, the mirror 16 is disposed between the junction J (see FIG. 4) of the apex A4 and the camera 11 and is inclined by 45 ° with respect to the optical axis of the camera 11. Thus, the camera 11 can capture a mirror image of the joint J of the apex A4 reflected on the mirror 16.
　アクチュエータ１８は、ミラー１６を、待機位置（フォーマーＡ２の外側）からエーペックスＡ４の接合部Ｊの鏡像を映すための検査位置まで進入させると共に、検査位置から待機位置まで退避させる装置である。 The actuator 18 is a device that moves the mirror 16 from the standby position (outside the former A2) to the inspection position for projecting the mirror image of the joint J of the apex A4 and retracts from the inspection position to the standby position.
　図３に示すように、アクチュエータ１８は、先端にミラー１６が取り付けられたミラー支持体２０と、ミラー支持体２０のガイド機構部２１と、ミラー支持体２０を往復動させるエアシリンダー２２とを備えている。アクチュエータ１８のガイド機構部２１は保持部２３に固定されており、この保持部２３にはカメラ１１も取り付けられている。図３中の１７Ａは照明器具１７の支持体であって、保持部２３に取り付けられている。 As shown in FIG. 3, the actuator 18 includes a mirror support 20 having a mirror 16 attached to the tip, a guide mechanism portion 21 of the mirror support 20, and an air cylinder 22 that reciprocates the mirror support 20. ing. The guide mechanism portion 21 of the actuator 18 is fixed to a holding portion 23, and the camera 11 is also attached to the holding portion 23. 3A is a support body of the lighting fixture 17, and is attached to the holding portion 23.
　そして、アクチュエータ１８によりミラー１６をエーペックスＡ４の接合部Ｊの正面から所定の距離だけ離れた位置（接合部Ｊの垂直方向の位置）まで進入させて接合部Ｊの鏡像を映して、カメラで撮影した後、この位置からフォーマーＡ２の外側まで退避させる（図２（ｂ）参照）。 Then, the actuator 18 moves the mirror 16 to a position (a position in the vertical direction of the joint J) that is a predetermined distance away from the front face of the joint J of the apex A4, reflects the mirror image of the joint J, and takes a picture with a camera. After that, it is retracted from this position to the outside of the former A2 (see FIG. 2B).
　そして、照明器具１７により、エーペックスＡ４の接合部Ｊに背後から光を照射し、エーペックスＡ４の接合部Ｊの鏡像をミラー１６に映すことにより、カメラ１１でエーペックスＡ４の接合部Ｊを撮像する。 Then, the illumination fixture 17 irradiates the junction J of the apex A4 with light from behind, and the mirror image of the junction J of the apex A4 is reflected on the mirror 16, whereby the junction J of the apex A4 is imaged by the camera 11.
２．画像処理装置の動作
　次に、エーペックス貼付工程における画像処理装置の動作について説明する。 2. Next, the operation of the image processing apparatus in the apex pasting process will be described.
（１）前記した通り、エーペックス貼付工程においては、ビードエーペックスジョイント装置Ａが使用され、ビードＡ１をビード投入装置からフォーマーＡ２に受け渡してこのフォーマーＡ２にビードＡ１をセットする。 (1) As described above, in the apex pasting step, the bead apex joint device A is used, and the bead A1 is transferred from the bead loading device to the former A2, and the bead A1 is set in the former A2.
（２）次に、フォーマーＡ２においてビードＡ１の外周にエーペックスＡ４を巻き付け、エーペックスＡ４の先端部と後端部とを圧着ローラＡ３で接合してエーペックス付ビードを形成する。 (2) Next, in the former A2, the apex A4 is wound around the outer periphery of the bead A1, and the front end and the rear end of the apex A4 are joined by the pressure roller A3 to form a bead with apex.
　この（１）、（２）においては、ビードＡ１のフォーマーＡ２への受け渡しや、エーペックス付ビードのフォーマーＡ２から蹴り出しなどに伴うミラー１６とビードＡ１との干渉を避けるために、画像処理装置のミラー１６は退避位置に退避している。 In (1) and (2), in order to avoid interference between the mirror 16 and the bead A1 due to delivery of the bead A1 to the former A2 or kicking out from the former A2 of the bead with apex, The mirror 16 is retracted to the retracted position.
（３）次に、アクチュエータ１８を伸長させることにより、画像処理装置のミラー１６を検査位置（接合部Ｊの垂直方向の位置）まで進入させる。これにより、エーペックスＡ４の接合部Ｊの画像が、ミラー１６を介してカメラ１１で撮像されて接合部Ｊの検査が行われる。なお、検査時には照明器具１７を発光させる。 (3) Next, the mirror 18 of the image processing apparatus is advanced to the inspection position (the position in the vertical direction of the joint portion J) by extending the actuator 18. Thereby, the image of the joint portion J of the apex A4 is captured by the camera 11 via the mirror 16, and the joint portion J is inspected. Note that the lighting device 17 is caused to emit light during inspection.
（４）検査完了後は、アクチュエータ１８を収縮させることにより、ミラー１６をフォーマーＡ２の周辺に退避させた後、エーペックス付ビードを、図外のストック装置に向けてフォーマーＡ２から蹴り出す。 (4) After the inspection is completed, the actuator 18 is contracted to retract the mirror 16 to the periphery of the former A2, and then the bead with apex is kicked from the former A2 toward the stock device (not shown).
　なお、適正な検査位置については、検査対象によっても異なるため、検査対象に応じて適宜、適正な位置に設定される。 In addition, since an appropriate inspection position varies depending on an inspection object, an appropriate position is appropriately set according to the inspection object.
３．本実施の形態の効果
（１）エーペックス付ビードのエーペックスＡ４の接合部Ｊの垂直方向には、カメラ１１と比べてスペースを余り必要としないミラー１６を配置するため、フォーマーＡ２の周辺などに種々の機構が備わっていることによりスペース上の制約を受ける場合であっても、エーペックスＡ４の接合部Ｊの垂直方向からの高精度の画像を取得することができる。 3. Advantages of the present embodiment (1) In the vertical direction of the joint J of the apex A4 of the bead with the apex, a mirror 16 that requires less space than the camera 11 is arranged, so that there are various effects around the former A2. Even when the space is restricted due to the provision of the mechanism, a highly accurate image from the vertical direction of the joint J of the apex A4 can be acquired.
（２）また、検査時にのみ、ミラー１６を待機位置から検査位置まで移動させるため、ビードＡ１のフォーマーＡ２への受け渡しや、エーペックス付ビードのフォーマーＡ２から蹴り出しなどに伴うミラー１６とビードＡ１との干渉の問題を解決することができる。 (2) Further, since the mirror 16 is moved from the standby position to the inspection position only at the time of inspection, the mirror 16 and the bead A1 associated with delivery of the bead A1 to the former A2 or kicking out of the bead with apex A2 The problem of interference can be solved.
（３）この結果、エーペックス貼付工程において、画像処理装置によるエーペックスＡ４の接合部Ｊの検査が可能になるため、作業者の負担の軽減と検査精度の向上を図ることができる。 (3) As a result, in the apex pasting step, the inspection of the joint J of the apex A4 can be performed by the image processing apparatus, so that the burden on the operator can be reduced and the inspection accuracy can be improved.
（４）本実施の形態の画像処理装置の検査対象は、上記のエーペックスには限られず、被測定物を垂直方向から撮影することがスペース上の問題から困難な場合に広く適用できる。 (4) The inspection target of the image processing apparatus according to the present embodiment is not limited to the above-described apex, and can be widely applied when it is difficult to photograph the object to be measured from the vertical direction due to space problems.
１．本実施例においては、ホットフィット設備に、上記した本実施の形態の画像処理装置を用いて、１本のビードにエーペックスを巻き付け、エーペックスの先端部と後端部を接合してエーペックス付ビードを形成し、エーペックスの接合部の状況について、カメラ撮影により検査した結果と、検査後に一本一本目視で確認した接合部の状況を比較して、本実施の形態の画像処理装置の信頼性について調査した。 1. In this example, the apex is wound around one bead using the image processing apparatus of the present embodiment described above in a hot fit facility, and the apex and rear end of the apex are joined to form a bead with apex. About the reliability of the image processing apparatus according to the present embodiment, comparing the results of inspection by camera shooting with respect to the status of the junction of the apex formed and the status of the junction confirmed visually one by one after the inspection investigated.
　画像処理装置のミラー１６としては、ステンレス板を鏡面仕上げしたものを採用し、画像センサーＢは、キーエンス製のＣＶ３０００、カメラ１１はキーエンス製のＣＶ０３５をそれぞれ用い、照明器具１７は、日進電子工業製ＬＴＵ－９０９０を用いた。 The mirror 16 of the image processing apparatus employs a mirror-finished stainless steel plate, the image sensor B uses CV3000 made by Keyence, the camera 11 uses CV035 made by Keyence, and the lighting fixture 17 is made by Nisshin Electronics.
