And disconnect. The two ends of the bead wire 101 after cutting face each other at a predetermined interval.

図３に示すように、可動板１０を上方へ移動させて、結線用チューブ保持部材の半部分８を半部分７から遠ざける。断面形状を図４に示す両端部が中空で中央部が中実の結線用チューブ１１を半部分７のチューブ保持溝７ａに嵌合させ、両端を接続溝７ｄ、７ｅに接近して対峙させる。可動板１０を下方へ移動させ、結線用チューブ保持部材の半部分８を半部分７に重ね合わせて両者を一体に組み付け、図５に示すように結線用チューブ保持部材１２を組み立てる。 As shown in FIG. 3, the movable plate 10 is moved upward to move the half portion 8 of the connection tube holding member away from the half portion 7. The cross-sectional shape shown in FIG. 4 is such that the connecting tube 11 having both hollow ends and a solid central portion is fitted into the tube holding groove 7a of the half portion 7, and both ends are brought close to and connected to the connecting grooves 7d and 7e. The movable plate 10 is moved downward, the half portion 8 of the connection tube holding member is overlapped with the half portion 7 and they are assembled together, and the connection tube holding member 12 is assembled as shown in FIG.

結線用チューブ保持部材１２の一端に開口する円錐台状の案内溝７ｆ、８ｆが協働して形成した漏斗状の案内穴１３の大径端部に、図５に実線で示すようにビードワイヤー１０１の一方の端末近傍部１０１ａ側の端末を差込み、図５に一点鎖線で示すように案内穴１３の斜面に沿って前記端末を前進させ、案内穴１３の小径端部から、接続溝７ｂ、８ｄが協働して形成した接続穴を介して、結線用チューブ１１の一方の中空部に進入させ、当該中空部の奥端まで前進させる。
結線用チューブ保持部材１２の一端に開口する円錐台状の案内溝７ｇ、８ｇが協働して形成した漏斗状の案内穴１４の大径端部に、図５に実線で示すようにビードワイヤー１０１の他方の端末近傍部１０１ｂの端末を差込み、図５に一点鎖線で示すように案内穴１４の斜面に沿って前記端末を前進させ、案内穴１４の小径端部から、接続溝７ｅ、８ｅが協働して形成した接続穴を介して、結線用チューブ１１の他方の中空部に進入させ、当該中空部の奥端まで前進させる。 As shown by the solid line in FIG. 5, a bead wire is formed at the large-diameter end of the funnel-shaped guide hole 13 formed by the cooperation of the frusto-conical guide grooves 7f and 8f opened at one end of the tube holding member 12 for connection. 101, the terminal on the side of one terminal vicinity 101a is inserted, and the terminal is advanced along the slope of the guide hole 13 as shown by a one-dot chain line in FIG. 8d is made to enter one hollow part of the tube 11 for connection through the connection hole formed in cooperation, and is advanced to the back end of the said hollow part.
As shown by the solid line in FIG. 5, a bead wire is formed at the large-diameter end of the funnel-shaped guide hole 14 formed by the cooperation of the truncated cone-shaped guide grooves 7g and 8g opened at one end of the connection tube holding member 12. 101, the terminal of the other terminal vicinity 101b is inserted, and the terminal is advanced along the inclined surface of the guide hole 14 as shown by a one-dot chain line in FIG. Are made to enter the other hollow portion of the connection tube 11 through the connection hole formed in cooperation with each other, and are advanced to the back end of the hollow portion.

可動板１０を上方へ移動させ、結線用チューブ保持部材１２を一対の半部分７、８に分離し、ビードワイヤー１０１の端末結線部を持ち上げて、ビードワイヤー１０１の端末結線部を結線用チューブ保持部材１２から離脱させる。
上記工程によりビードワイヤー１０１の両端末は、タイヤビード１００の内周面側で結線され、タイヤビード１００の内周面に密着する。
第１エアカッターの刃２ａ、２ｂと第２エアカッターの刃３ａ、３ｂ間の距離を適正値に設定して、ビードワイヤー１０１の両端末を結線した際に、ビードワイヤー１０１の両端末が結線用チューブ１１の両中空部の奥端壁に押し当てられて、両者間に適正な反力が働くようにしておけば、ビードワイヤー１０１の両端末が結線用チューブ１１から抜け落ちる事態の発生を防止できる。 The movable plate 10 is moved upward, the connection tube holding member 12 is separated into a pair of halves 7 and 8, the terminal connection portion of the bead wire 101 is lifted, and the terminal connection portion of the bead wire 101 is held by the connection tube. The member 12 is separated.
Through the above process, both ends of the bead wire 101 are connected on the inner peripheral surface side of the tire bead 100 and are in close contact with the inner peripheral surface of the tire bead 100.
When the distance between the blades 2a and 2b of the first air cutter and the blades 3a and 3b of the second air cutter is set to an appropriate value and both ends of the bead wire 101 are connected, both ends of the bead wire 101 are connected. If it is pressed against the back end walls of both hollow portions of the tube 11 so that an appropriate reaction force acts between them, the occurrence of a situation in which both ends of the bead wire 101 fall out of the connection tube 11 is prevented. it can.

上記説明から分かるように、本実施例に係るタイヤビードのビードワイヤー両端末結線装置においては、互いに所定間隔を隔てた第１エアカッターと第２エアカッターとを用いることにより、ビードワイヤー１０１の両端末が所定の間隔を隔てて互いに対峙するように、ビードワイヤー１０１の両端末部を容易に切断することができる。また、両端部に漏斗状の案内穴１３、１４が形成された結線用チューブ保持部材１２を用いることにより、ビードワイヤー１０１の両端末を結線用チューブ１１まで容易に案内できるので、ビードワイヤー１０１の両端末結線作業の作業効率が従来に比べて向上する。 As can be seen from the above description, in the bead wire both ends connecting device for tire beads according to the present embodiment, both of the bead wires 101 are used by using the first air cutter and the second air cutter which are spaced apart from each other. Both terminal portions of the bead wire 101 can be easily cut so that the terminals face each other at a predetermined interval. In addition, since both ends of the bead wire 101 can be easily guided to the connecting tube 11 by using the connecting tube holding member 12 having funnel-shaped guide holes 13 and 14 formed at both ends, the bead wire 101 The work efficiency of both terminal connection work is improved as compared with the conventional case.

エアカッターは作動が迅速で、ビードワイヤー１０１の両端末部を瞬時に切断できるので、切断部が塑性変形を起こして偏平に広がるのを防止でき、結線用チューブ１１に挿入可能とするために偏平に広がった部分を削ぎ落とす作業の発生を防止できる。この結果、ビードワイヤー１０１の両端末結線作業の作業効率が更に向上する。 The air cutter operates quickly and can instantaneously cut both end portions of the bead wire 101, so that the cut portion can be prevented from plastically deforming and spreading flat, and can be inserted into the connection tube 11. It is possible to prevent the occurrence of the work of scraping off the part spread over. As a result, the work efficiency of the work for connecting both terminals of the bead wire 101 is further improved.

エアカッターに代えて電動カッターや油圧カッターを使用しても良い。但しこの場合には、塑性変形を起こして偏平に広がった切断部を削ぎ落とす作業が必要になる。
結線用チューブ１１に代えて全体が中空の結線用チューブを使用しても良い。この場合、結線用チューブ内にビードワイヤーの両端末を確実に存在させるために、結線用チューブの中央部を潰しても良い。また、潰されて偏平に広がった結線用チューブ中央部を収容するための大径溝部を、チューブ保持部材のチューブ保持溝の中央部に形成しても良い。 An electric cutter or a hydraulic cutter may be used instead of the air cutter. In this case, however, it is necessary to scrape off the cut portion that has been flattened due to plastic deformation.
Instead of the connection tube 11, a connection tube that is entirely hollow may be used. In this case, the central portion of the connection tube may be crushed in order to ensure that both ends of the bead wire exist in the connection tube. Moreover, you may form the large diameter groove part for accommodating the center part of the tube for wiring which was crushed and spread flatly in the center part of the tube holding groove of a tube holding member.
