【発明の属する技術分野】
本発明は、内燃機関の排気ガス浄化のための触媒コンバータ等に使用されるメタル担体において、メタル担体を構成するハニカム部を外筒内に挿入した状態でハニカム部と外筒との間をろう付けにより一体化させる場合に、ハニカム部の外周にろう箔材を巻き付けるためにろう箔材の端部を各ハニカム部における外周上面側のスポット溶接位置に順次送り込むためのメタル担体のろう箔材送り装置に関する。
【０００２】
【従来の技術】
従来、メタル担体を構成するハニカム部の外周にろう箔材を巻き付けた状態で、外筒内に挿入してハニカム部と外筒との間をろう付けにより一体化させた構造のメタル担体としては、例えば、実開平４−１４１３５号公報に記載された「排ガス浄化触媒用メタル担体」が知られている。
なお、この従来例においては触れられていないが、ハニカム部にろう箔材を送り込むためのメタル担体のろう箔材送り装置としては、図９に示すように、ろう箔材１０２を上下方向から挟持可能な上下一対の送りハンド部１０３、１０４を備え、この送りハンド部１０３、１０４でろう箔材１０２の中途部を挟持した状態でハニカム部１０１へ向けて水平方向へ移動さることにより、ろう箔材１０２の端部をハニカム部１０１における外周上面側のスポット溶接１０５位置に順次送り込むように構成されたものが用いられている。
【０００３】
【発明が解決しようとする課題】
しかしながら、従来用いられているろう箔材送り装置の送りハンド部は、図１０のハンド部１０３、１０４の縦断面図に示すように、ろう箔材挟持面が直線状に形成されたものであったため、以下に述べるように問題点があった。
即ち、ハニカム部１０１と外筒との間のろう付けに用いられるろう箔材１０２は、２５μ程度と極めて薄いため、送りハンド部１０３、１０４で中途部を挟持した片持ち状態で先端側突出部分を水平状態に維持させることは容易ではなく、このため、図９に示すように、ろう箔材１０２の突出部分がその重みで下方へ撓むおそれがあり、従って、ろう箔材１０２の端部をハニカム部１０１における所定のスポット溶接１０５位置に送り込むことができなくなる場合がある。
【０００４】
本発明の解決しようとする課題は、送りハンド部で中途を挟持したろう箔材の先端側突出部分の撓みを防止してろう箔材の端部をハニカム部における所定のスポット溶接位置に確実に送り込むことができるメタル担体のろう箔材送り装置を提供することにある。
【０００５】
【課題を解決するための手段】
上記課題を解決するため本発明請求項１記載のメタル担体のろう箔材送り装置では、ろう箔材を上下方向から挟持可能な上下一対の送りハンド部を備え、該送りハンド部はろう箔材の中途部を挟持した状態でハニカム部へ向けて水平方向へ移動可能に構成されることによりろう箔材の端部をハニカム部における外周面のスポット溶接位置まで移送し、該ろう箔材端部の中央部をハニカム体の上面側に当接させて、この中央部をスポット溶接することによりハニカム部に対するろう箔材の先端部の固定を完了させた後、送りハンドル部によるろう箔材の挟持を解除させた状態でハニカム部の外周面に対するろう箔材の巻き付け固定作業に移るようにしたメタル担体のろう箔材送り装置であって、
前記上下一対の送りハンド部における挟持面がろう箔材の幅方向においてその中央部が両端部より下方向に位置がずれた非直線状に形成されていることを特徴とする手段とした。
【０００６】
請求項２記載のメタル担体のろう箔材送り装置では、請求項１において、前記挟持面がろう箔材の幅方向において中央部が両端部より低くなる下向き円弧状に形成されている手段とした。
【０００７】
請求項３記載のメタル担体のろう箔材送り装置では、請求項１において、前記挟持面がろう箔材の幅方向において中央部が両端部より低くなるＶ字状に形成されている手段とした。
【０００８】
【作用および効果】
請求項１記載の発明では、上述のように構成されるため、ろう箔材の中途部を上下一対の送りハンド部で挟持すると、該挟持面がろう箔材の幅方向においてその中央部が両端部より下方向に位置がずれた非直線状に形成されているため、ろう箔材が挟持面の形状に沿って非直線状に変形された状態となるもので、これにより、長手方向における上下方向への曲げ強度が強くなる。従って、送りハンド部で中途を挟持したろう箔材の先端側突出部分の撓みを防止してろう箔材の端部をハニカム部における所定のスポット溶接位置に確実に送り込むことができるようになるという効果が得られる。
【０００９】
また、前記挟持面がろう箔材の幅方向において中央部が両端部より低くなるため、ハニカム部の上面側であって幅方向中央部にスポット溶接する場合においては、ろう箔材のスポット溶接部がハニカム部の上面側に当接した状態となるため、スポット溶接作業を的確に行えるようになる。
【００１０】
【発明の実施の形態】
（発明の実施の形態１）
この発明の実施の形態１のメタル担体のろう箔材送り装置は、請求項１、２に記載の発明に対応する。
【００１１】
図１はこの発明の実施の形態１のメタル担体のろう箔材送り装置を示す側面図、図２は送りハンド部の拡大側面図、図３は送りハンド部の拡大正面図、図４は上側ハンド部の底面図、図５は下側ハンド部の平面図であり、これらの図において、１は装置基台部、２は上下一対の送りハンド部である。
【００１２】
前記送りハンド部２は、上側ハンド２１部と下側ハンド部２２とで構成されていて、両上下一対のハンド部２１、２２は、それぞれ装置基台部１に対し前後方向に往復移動可能に設けられた水平移動部１１に対し、それぞれ上下方向に移動可能に設けられた上下一対の挟持アーム１２、１３に対し、それぞれ着脱可能に取り付けられている。
【００１３】
前記両上下一対のハンド部２１、２２の対向面には、ろう箔材３３の中途部を挟持するための挟持体２１ａ、２２ａがそれぞれ備えられている。そして、この両挟持体２１ａ、２２ａの互いに対向する挟持面は、水平移動部１１の移動方向と直交する幅方向、即ち、挟持するろう箔材３３の幅方向においてその中央部が両端部より低くなる下向き円弧状に形成されている。また、前記、両挟持体２１ａ、２２ａの互いに対向する挟持面を含む外表面にはウレタン樹脂よりなる被覆層が形成されている。
【００１４】
一方、前記メタル担体３は、図６に示すように、金属製の平板３１ａと波板３１ｂとを交互に重ねて多重に巻回したハニカム部３１の外周面にニッケル等のろう箔材３３を巻き付けた状態で外筒３２内に挿入し、この状態で熱処理によりろう箔材３３を溶融させることにより、ハニカム部３１と外筒３２との間をろう付けにより接合一体化させた構造となっている。
【００１５】
また、前記ハニカム部３１のハニカム通路表面には、アルミナ等からなる触媒担持層が形成され、その触媒担持層に触媒金属が担持されることにより、排ガス浄化触媒とされ、内燃機関の排気通路に配置されることにより、排気ガス中のＨＣ、ＣＯ、ＮＯｘ等を浄化させるようになっている。
【００１６】
そして、前記ハニカム部３１は、図７に作用説明図を示すように、ろう箔材送り装置によるろう箔材３３の送り出し方向に位置決め配置されていて、送りハンド部３による送り出しにより、ろう箔材３３の先端部がハニカム部３１の上面側に送り込まれるようになっている。
【００１７】
この発明の実施の形態１のメタル担体のろう箔材送り装置では、上述のように構成されるため、図７に示すように、ろう箔材３３の中途部を送りハンド部２の上側ハンド２１部と下側ハンド部２２との間で挟持すると、挟持体２１ａ、２２ａの挟持面がろう箔材３３の幅方向においてその中央部が両端部より低くなる下向き円弧状に形成されているため、ろう箔材３３が挟持面の円弧形状に沿って下向き円弧状に変形された状態となるもので、これにより、長手方向における上下方向への曲げ強度が強くなり、先端側突出部分の下方への撓みが防止された状態となる。
【００１８】
即ち、前述のように、ろう箔材３３は、２５μ程度と極めて薄く保形力に欠けるため、送りハンド部２で中途部を挟持した片持ち状態で先端側突出部分を水平状態に維持させることは容易ではなく、平面状態のままではろう箔材３３の突出部分がその重みで下方へ撓むおそれがあったが、上述のように、下向き円弧状に変形させることにより、長手方向における上下方向への曲げ強度が強くなり、これにより、片持支持状態であっても、ろう箔材３３の端部を水平に突出させた状態に維持させることができるようになる。
【００１９】
そこで、この状態で、送りハンド部２をハニカム部３１へ向けて水平方向へ移動させることにより、ろう箔材３３の端部をハニカム部３１における外周面の上面側スポット溶接位置まで確実に移送することができる。そして、この移送された状態においては、ろう箔材３３の端部の少なくとも幅方向中央部がハニカム部３１の上面側に当接した状態となるため、この端部の中央部分をスポット溶接Ｐすることにより、ハニカム部３１に対する先端部の固定が完了し、その後は、送りハンド部２によるろう箔材３３の挟持を解除させた状態で、ハニカム部３１の外周面に対するろう箔材３３の巻き付け固定作業に移ることになる。
【００２０】
以上詳細に説明してきたように、この発明の実施の形態１のメタル担体のろう箔材送り装置にあっては、送りハンド部２で中途を挟持したろう箔材３３の先端側突出部分の撓みを防止してろう箔材３３の端部をハニカム部３１における所定のスポット溶接Ｐ位置に確実に送り込むことができるようになるという効果が得られる。
【００２１】
また、前記両挟持体２１ａ、２２ａの互いに対向する挟持面を、水平移動部１１の移動方向と直交する幅方向、即ち、挟持するろう箔材３３の幅方向においてその中央部が両端部より低くなる下向き円弧状に形成したことで、この発明の実施の形態１におけるようにハニカム部３１の上面側であって幅方向中央部にスポット溶接Ｐする場合においては、ろう箔材３３のスポット溶接Ｐ部がハニカム部３１の上面側に当接する状態に移送できるため、スポット溶接作業を的確に行えるようになるという効果が得られる。
【００２２】
（発明の実施の形態２）
この発明の実施の形態２のメタル担体のろう箔材送り装置は、請求項１、３に記載の発明に対応する。なお、この発明の実施の形態２のメタル担体のろう箔材送り装置は、送りハンド部２の形状が一部相違するのみで、その他の構成は前記発明の実施の形態１と同様であるため、相違点についてのみ説明する。
【００２３】
即ち、この発明の実施の形態２のメタル担体のろう箔材送り装置は、図８に示すように、前記両上下一対のハンド部２１、２２の対向面に備えられた両挟持体２１ａ、２２ａの互いに対向する挟持面が、水平移動部１１の移動方向と直交する幅方向、即ち、挟持するろう箔材３３の幅方向においてその中央部が両端部より低くなるＶ字状に形成された点が、前記発明の実施の形態１と相違するものである。
【００２４】
この発明の実施の形態２のメタル担体のろう箔材送り装置では、上述のように構成されるため、図８に示すように、ろう箔材３３の中途部を送りハンド部２の上側ハンド２１部と下側ハンド部２２との間で挟持すると、挟持体２１ａ、２２ａの挟持面がろう箔材３３の幅方向においてその中央部が両端部より低くなるＶ字状に形成されているため、ろう箔材３３が挟持面の円弧形状に沿ってＶ字状に変形された状態となるもので、これにより、長手方向における上下方向への曲げ強度が強くなり、先端側突出部分の下方への撓みが防止された状態となる。
【００２５】
そこで、この状態で、送りハンド部２をハニカム部３１へ向けて水平方向へ移動させることにより、ろう箔材３３の端部をハニカム部３１における外周面の上面側スポット溶接位置まで確実に移送することができる。そして、この移送された状態においては、ろう箔材３３の端部の少なくとも幅方向中央部がハニカム部３１の上面側に当接した状態となるため、この端部の中央部分をスポット溶接Ｐすることにより、ハニカム部３１に対する先端部の固定が完了し、その後は、送りハンド部２によるろう箔材３３の挟持を解除させた状態で、ハニカム部３１の外周面に対するろう箔材３３の巻き付け固定作業に移ることになる。
従って、この発明の実施の形態２のメタル担体のろう箔材送り装置によれば、前記発明の実施の形態１と同様の効果が得られる。
【００２６】
以上本発明の実施の形態を説明してきたが、本発明は上述の発明の実施の形態に限られるものではなく、本発明の要旨を逸脱しない範囲の設計変更等があっても、本発明に含まれる。

FIG. 5 is a plan view of the lower hand unit. In these drawings, 1 is an apparatus base unit, and 2 is a pair of upper and lower feed hand units.
[0012]
The feeding hand portion 2 is composed of an upper hand portion 21 and a lower hand portion 22, and the pair of upper and lower hand portions 21, 22 can reciprocate in the front-rear direction with respect to the device base portion 1. Removably attached to a pair of upper and lower sandwiching arms 12 and 13 provided to be movable in the vertical direction with respect to the horizontal moving portion 11 provided.
[0013]
The opposing surfaces of the pair of upper and lower hand portions 21 and 22 are respectively provided with sandwiching bodies 21a and 22a for sandwiching a midway portion of the brazing foil material 33. The sandwiching surfaces of the sandwiching bodies 21a and 22a facing each other are lower in the width direction perpendicular to the moving direction of the horizontal moving part 11, that is, in the width direction of the brazing foil material 33 to be sandwiched, than the center part thereof. It is formed in the downward arc shape. Further, a coating layer made of urethane resin is formed on the outer surface including the sandwiching surfaces facing each other of the sandwiching bodies 21a and 22a.
[0014]
On the other hand, as shown in FIG. 6, the metal carrier 3 has a brazing foil material 33 such as nickel on the outer peripheral surface of a honeycomb portion 31 in which metal flat plates 31a and corrugated plates 31b are alternately stacked and wound in multiple layers. It is inserted into the outer cylinder 32 in a wound state, and the brazing foil material 33 is melted by heat treatment in this state, so that the honeycomb portion 31 and the outer cylinder 32 are joined and integrated by brazing. Yes.
[0015]
Further, a catalyst support layer made of alumina or the like is formed on the surface of the honeycomb passage of the honeycomb portion 31, and a catalyst metal is supported on the catalyst support layer to be an exhaust gas purification catalyst. By being arranged, HC, CO, NOx, etc. in the exhaust gas are purified.
[0016]
The honeycomb portion 31 is positioned and arranged in the feeding direction of the brazing foil material 33 by the brazing foil material feeding device, as shown in FIG. 7, and the brazing foil material is fed by the feeding hand portion 3. The distal end portion 33 is fed into the upper surface side of the honeycomb portion 31.

Therefore, the protruding portion on the front end side is maintained in a horizontal state in a cantilever state in which the midway portion is sandwiched by the feeding hand portion 2. However, in the flat state, the protruding portion of the brazing foil material 33 may be bent downward due to its weight. However, as described above, by deforming in a downward arc shape, the vertical direction in the longitudinal direction As a result, the end portion of the brazing foil material 33 can be maintained in a state of projecting horizontally even in the cantilever support state.
[0019]
Therefore, in this state, by moving the feed hand portion 2 toward the honeycomb portion 31 in the horizontal direction, the end portion of the brazing foil material 33 is reliably transferred to the spot welding position on the outer peripheral surface of the honeycomb portion 31. be able to. In this transferred state, since at least the center portion in the width direction of the end portion of the brazing foil material 33 is in contact with the upper surface side of the honeycomb portion 31, the center portion of this end portion is spot welded P. Thus, the fixing of the tip portion to the honeycomb portion 31 is completed, and thereafter, the brazing foil material 33 is wound and fixed around the outer peripheral surface of the honeycomb portion 31 in a state where the sandwiching of the brazing foil material 33 by the feeding hand portion 2 is released.

As described above in detail, in the brazing foil material feeding device for a metal carrier according to the first embodiment of the present invention, the bending of the protruding portion on the front end side of the brazing foil material 33 sandwiched halfway by the feeding hand portion 2 is performed. Thus, the effect that the end portion of the brazing foil material 33 can be reliably fed to the predetermined spot weld P position in the honeycomb portion 31 is obtained.
[0021]
Further, the sandwiching surfaces of the sandwiching bodies 21a and 22a facing each other are arranged such that the central portion thereof is lower than both ends in the width direction orthogonal to the moving direction of the horizontal moving portion 11, that is, in the width direction of the brazing foil material 33 to be sandwiched. In the case where spot welding P is performed on the upper surface side of the honeycomb portion 31 and the center portion in the width direction as in the first embodiment of the present invention, the spot welding P of the brazing foil material 33 is formed.
