【発明の属する技術分野】
本発明は、電気配線材として用いられ、1または2以上の細幅導体箔よりなる配線パターンが一対の絶縁フィルムの間に挟み込まれてなるフラット配線体の製造方法であって、特に、フラット配線体を、製造ライン上に走行される一連のテープ状積層体から所定部分を外形打抜きすることにより得るフラット配線体の製造方法に関する。
【0002】
【従来の技術】
このようなフラット配線体の製造方法としては、本出願人が特開平6−68722号公報において提案したものが知られている。フラット配線体の概略製造工程を図1に示す例に基づいて説明すると、まず、製造ラインLに沿って走行される比較的厚肉で粘着層を有するキャリアテープ1の上に銅箔Uが粘着され、その銅箔Uのみが所定の配線パターンの形状に沿って順次打ち抜かれる(ハーフカット工程P1)。この後、配線パターン2を除く残材部である他の銅箔部分Ur が除去され(残材部除去工程P2)、キャリアテープ1上に配線パターン2のみが粘着された状態で残される。次に、この配線パターン2がキャリアテープ1から比較的薄肉で接着剤層を有するテープ状絶縁フィルム3に転写されてキャリアテープ1が剥離され(転写工程P3)、これにより、上記配線パターン部2の片面が絶縁フィルム3上に接着された状態(図2の右側の破断部分参照)になる。そして、その配線パターン部2,2,…の上面に他の絶縁フィルム3がラミネートされて接着されてテープ状積層体4とされ(ラミネート工程P4)、次に、このテープ状積層体4に対し外形打抜き機5による打ち抜きにより1単位の配線パターン部2毎にその配線パターン2の外周形状に沿って全周に切れ目6(図3参照)が入れられ(外形打抜き工程P5)、この切れ目6によって、テープ状積層体4がフラット配線体部分7と、これ以外のテープ残部8とに分離区画される。この状態で製造ラインL上を次工程まで搬送された後、上記フラット配線体部分7がテープ状積層体4から取り出され(製品回収工程P6)、これにより、図3に示すように、配線パターン2の上下面が一対の絶縁フィルム3,3の間の各接着剤層3aにより接着され、かつ、所定の外形に成形された製品としてのフラット配線体Fが回収、収納される。
【0003】
なお、図2及び図3では、3本の細幅導体箔21,21,21により構成された回路パターン2を例示し、また、図3では、肉厚を大幅に誇張して図示している。
【0004】
【発明が解決しようとする課題】
ところが、上記従来のフラット配線体の製造方法においては、外形打抜き工程P5においてフラット配線体部分7の全周が打抜かれているため、外形打抜き工程P5から製品回収工程P6まで製造ライン上を搬送する間にテープ状積層体からフラット配線体部分7が脱落したり、脱落しないまでも位置ずれした状態で引きずられたりするおそれがある。このような事態が生じると、本来、テープ状積層体4上に一定間隔で整列して製品回収工程P6まで搬送されてくるフラット配線体部分7の位置がばらばらとなって、製品Fの回収自体が困難になったり、回収した製品Fを所定位置に整列させて収納することが困難になったりする。
【0005】
本発明は、このような事情に鑑みてなされたものであり、その目的とするところは、外形打抜き後のフラット配線体の回収を確実に行うことにある。
【0006】
【課題を解決するための手段】
上記目的を達成するために、請求項1記載の発明は、一対のテープ状絶縁フィルム間に導体箔よりなる回路パターンが順次介装されたテープ状積層体を製造ラインに沿って下流側に走行させ、そのテープ状積層体に対し外形打抜き機で上記回路パターンよりも大きい外周形状に沿って打抜く外形打抜き工程により、フラット配線体部分と、フラット配線体部分を除くテープ残部とに分離区画するループ状の主切れ目を形成し、この後、上記外形打抜き機の下流側位置の製造ライン上において上記主切れ目が形成されたテープ状積層体からフラット配線体部分を回収する製品回収工程を行うフラット配線体の製造方法を対象とする。このものの上記外形打抜き工程において、上記外形打抜き機により打抜く際に上記主切れ目に沿って少なくとも1箇所に微小寸法にわたり切れ目を形成しない非打抜き部を残す一方、その非打抜き部を挟む両側の主切れ目からそれぞれテープ残部側に延びる一対の補助切れ目を形成することにより、その一対の補助切れ目間に一端側が上記フラット配線体部分と非打抜き部でのみ連続し他端側が上記非打抜き部よりも大きい寸法で上記テープ残部と連続する連結片部を区画形成する。そして、上記製品回収工程において、上記非打抜き部、この非打抜き部を挟む両側の主切れ目、及び、上記一対の補助切れ目を外側から包囲する包囲線に沿ってテープ状積層体を表裏から挟み付けて上記包囲線に沿う部分を同一平面位置に保持し、この保持した状態で表裏一側から上記連結片部を押圧バーで押圧することにより上記非打抜き部を破断する構成とするものである。
【0007】
上記の構成の場合、外形打抜き工程において、フラット配線体部分の全周ではなくその一部に微小寸法の非打抜き部を残した状態で主切れ目が形成され、併せて、その主切れ目から連続して一対の補助切れ目が形成され、これにより、テープ残部側に、フラット配線体部分側と上記非打抜き部でつながれた連結片部が区画形成される。このため、上記フラット配線体部分は非打抜き部でテープ残部側につながれて脱落したり位置ずれしたりすることなく次工程まで確実に搬送される。そして、製品回収工程において、その連結片部が押圧バーで押圧されると、その連結片部が一対の補助切れ目位置でテープ残部から離れて表裏他側に折れ曲がり、一端側の非打抜き部と、他端側のテープ残部とに引張力が作用することになる。そして、上記非打抜き部が微小寸法であるため、この非打抜き部を構成する微小幅の一対の絶縁フィルム等が容易に引張破断を生じてフラット配線体部分と連結片部とが互いに分離し、これにより、上記フラット配線体部分がテープ状積層体から完全に分離される。この際、非打抜き部、その両側の主切れ目、及び、一対の補助切れ目を外側から包囲するようにテープ状積層体が表裏から挟み付けられて内部が同一平面位置に保たれているため、上記押圧バーによる連結片部への押圧が有効に行われる上、その押圧の影響を製品となるフラット配線体部分に及ぼすことが確実に防止される。
【0008】
請求項2記載の発明は、請求項1記載の発明における外形打抜き工程において、非打抜き部を挟む両側の主切れ目からそれぞれ各主切れ目の延長方向に略直交する方向に延びる一対の直交補助切れ目と、この両直交補助切れ目の先端に連続して上記主切れ目に略平行に延びる一対の平行補助切れ目を形成する。そして、製品回収工程において、包囲線を、上記非打抜き部、この非打抜き部を挟む両側の主切れ目、上記一対の直交補助切れ目、及び、上記一対の平行補助切れ目を外側から包囲するように設定し、押圧バーで、上記一対の直交補助切れ目の中間位置の連結片部を押圧するようにするものである。
【0009】
上記の構成の場合、外形打抜き工程における一対の補助切れ目として、一対の直交補助切れ目と、各直交補助切れ目の先端から連続する一対の平行補助切れ目とを形成するようにしているため、押圧バーによる押圧力をより確実に連結片部にのみ作用させることが可能になる上、非打抜き部の破断がより容易に可能になる。
【0010】
請求項3記載の発明は、請求項2記載の発明において、一対の平行補助切れ目を、各直交補助切れ目の先端から互いに相反する側に延びるように形成するものである。
【0011】
上記の構成の場合、一対の平行補助切れ目が互いに相反する側に延びているため、各平行補助切れ目と、非打抜き部を挟む各側の主切れ目とで挟まれる部分が各直交補助切れ目によって連結片部と切り離される。このため、連結片部の両側に三方を切り離されて押圧バーで押圧されても自由移動し得る部分が存在することになり、押圧バーによる押圧位置が連結片部の側方に多少ずれて上記両側部分に押圧力が作用しても、テープ残部等に対し不要な引張力を作用させることはない。従って、製品回収工程において、テープ状積層体と押圧バーとの相対位置が多少ずれても支障なく非打抜き部の破断が行い得る。
【0012】
請求項4記載の発明は、請求項1または請求項2記載の発明の外形打抜き工程において、外形打抜き機による打抜きにより、主切れ目と補助切れ目とを同時に形成するものである。
【0013】
上記の構成の場合、外形打抜き機による1度の打抜きにより非打抜き部を残した主切れ目と、補助切れ目とが同時に形成され、効率化が図られる。
【0014】
また、請求項5記載の発明は、請求項1記載の発明の製品回収工程において、包囲線に沿って延びる先端周面を有する筒状弾性部材をテープ状積層体を挟んで少なくとも押圧バーと相対向する側に配し、その筒状弾性部材の先端周面を上記テープ状積層体に押し付けるようにするものである。
【0015】
上記の構成の場合、筒状弾性部材の先端周面を押し付けることにより、包囲線に沿った全周部分が弾性押圧され、その包囲線に沿った部分が確実に位置固定される上に、その押圧によるフラット配線体部分への損傷のおそれが確実に解消される。
【0016】
さらに、請求項6記載の発明は、請求項1記載の発明の製品回収工程において、フラット配線体部分を吸着手段で吸着保持し、非打抜き部を破断した後に、吸着手段を平行移動させることにより上記フラット配線体部分をテープ状積層体から分離して回収するものである。
【0017】
上記の構成の場合、テープ状積層体からの吸着手段の平行移動によるフラット配線体部分の分離回収によって、製品としてのフラット配線体を順次整然と積層状態もしくは並列状態にして収納させることが可能になる。
【0018】
【発明の実施の形態】
以下、本発明の実施形態を図面に基いて説明する。
【0019】
図4は、本発明の実施形態に係るフラット配線体の製造方法におけるラミネート工程P4以降の製造装置を示し、50が外形打抜き工程P50を行う外形打抜き機、60が製品回収工程P60を行う製品回収手段である。なお、本実施形態に係るフラット配線体の製造方法は、上記外形打抜き工程P50までの前工程において、図5の右側部分に示すように、回路パターン2を介装した状態で一対の絶縁フィルム3,3が互いに接着されたテープ状積層体4が形成されるものであればいずれの製造方法により形成されるものであっても適用することができる。そのテープ状積層体4を形成する製造方法としては、例えば、図1に示すようなハーフカット工程P1、残材部除去工程P2、転写工程P3、及び、ラミネート工程P4の各工程により構成すればよい。以下、上記の外形打抜き工程P50及び製品回収工程P60と、これらの各工程P50,P60で用いる外形打抜き機50及び製品回収手段60とについて詳細に説明する。
【0020】
(外形打抜き工程P50)
上記外形打抜き機50は、図4に示すように、例えばビクリア刃(ビク刃)により構成された打抜き刃51が下方に突出された上型52と、上面に比較的厚めの下敷きマット等を設けた下型53とを備えている。そして、テープ状積層体4を下型53の上面に載置した状態で上記上型52を下動させることにより、上記打抜き刃の形状と同じ切れ目を上記テープ状積層体4を上から下に貫通して形成するようになっている。
【0021】
上記打抜き刃51の形状は、図5及び図6に示すように、回路パターン2の外周をループ状に取り囲んで上記テープ状積層体4をフラット配線体部分7と残りのテープ残部8とに分離区画する主切れ目9と、上記回路パターン2の両端部に対応する位置の主切れ目9からテープ残部8の側にそれぞれ一対ずつ延ばされた補助切れ目10,10、10,10とが形成されている。また、上記打抜き刃51の上記主切れ目9に相当するループ状の刃の上記回路パターン2の両端部側の所定位置にはそれぞれ微小間隔の隙間が設けられており、これにより、上記主切れ目9の両端部にそれぞれ微小寸法S(例えば0.5〜1.0mm;図7参照)の非打抜き部11,11、すなわち、切れ目の形成されていない微小部分が残るようになっている。そして、上記各一対の補助切れ目10,10は、各非打抜き部11を挟む主切れ目9の両側部位9a,9aからその両側部位9a,9aの延びる方向に直交してテープ残部8の側にそれぞれ延びる一対の直交補助切れ目部10a,10aと、この各直交補助切れ目10aのたから連続して上記両側部位9a,9aと平行にかつ相反する側に延びる一対の平行補助切れ目部10b,10bとから構成されている。これにより、上記一対の直交補助切れ目10a,10a間に、一端側が非打抜き部11を介してフラット配線体部分7と連続し、他端側が上記非打抜き部11の微小寸法Sよりも大幅に大きい幅でテープ残部8と連続する連結片部12(図7参照)が区画形成されるようになっている。
【0022】
そして、この外形打抜き工程P50では、上記の上型52をテープ状積層体4を挟んで下型53側に下動させることにより打抜き刃51で上記テープ状積層体4を打抜き、これによって、上記の非打抜き部11,11を残して主切れ目9を形成すると同時に、この主切れ目9の両端部のそれぞれに連結片部12が区画形成されるように各一対の補助切れ目10,10を形成する。
【0023】
(製品回収工程P60)
製品回収手段60は、製造ラインLに沿って上記外形打抜き機50の下流側位置に配設されており、上面にテープ状積層体4が載置される下盤61と、この下盤61に対し相対向して上下方向及び製造ラインLの側方に平行に往復移動される上盤62とを備えている。この上盤61には、図6及び図8に示すように、一対の筒状弾性部材としての押さえ盤63,63と、一対の吸着手段64,64とが設けられている一方、上記下盤62には上記各押さえ盤63に相対向して一対の押圧バー65,65が設けられている。
【0024】
上記各押さえ盤63は、先端周面がテープ状積層体4に対する押さえ面63aとされ、発泡樹脂等のクッション性のある弾性素材により筒状に形成されたものである。そして、これら各押さえ盤63は、その押さえ面63aが外形打抜き工程P50終了後のテープ状積層体4における各連結片部12の周囲を包囲するように上記上盤61に配設されている。具体的には、上記各押さえ面63aが、上記各非打抜き部11を含み各非打抜き部11を挟む主切れ目9の両側部位9a,9aと、上記各一対の直交補助切れ目部10a,10aと、上記各一対の平行補助切れ目部10b,10bとを外側から包囲するようにテープ状積層体4を下盤62との間で押さえ付けて上記各連結片部12の周囲を仮固定するようになっている。
【0025】
上記各吸着手段64は、吸着パッド64aと、この吸着パッド64aに吸引用負圧を供給する管路64bとを備えており、この管路64bからの吸引用負圧の供給によりフラット配線体部分7を吸着パッド64aに吸引するようになっている。
【0026】
上記各押圧バー65は、シリンダ66(図8参照)のロッド66aの上端に固定され、このロッド66aの昇降により下盤62の貫通孔62aの上端開口から出没可能に配設されている。ここで、上記シリンダ66はブラケット67を介して下盤62の下面に取付けられ、また、上記押圧バー65とロッド66aと間にはストッパー68が介装されて上記貫通孔62aの下端開口縁に当接することにより上記押圧バー65のそれ以上の上動を阻止するようになっている。そして、上記各押圧バー65は、各連結片部12の幅よりも長く、かつ、各非打抜き部11(図7参照)を挟む主切れ目9の両側部位9a,9aの長さ、もしくは、一対の平行補助切れ目10b,10bをまたぐ配設長さの内の短い方のものよりも長くならない範囲の長さを有しており、上記各連結片部12に対し上方に押圧力を加えて上記各非打抜き部11を破断し得るように配設されている。すなわち、上記各押圧バー65は、上記各押さえ盤63の押さえ面63aにより押さえ付けられた状態の各連結片部12に対し、少なくともその各連結片部12の両端間の中間位置、望ましくはその両端間のほぼ中央位置を横切るように位置付けられている。
【0027】
そして、この製品回収工程P60では、外形打抜き機50から製品回収手段60まで送られてきたテープ状積層体4を位置決めして停止させ、このテープ状積層体4に対し上盤61を下動して両押さえ盤63,63の各押さえ面63aで押さえ付ける(図8の一点鎖線参照)とともに、両吸着64,64の吸着パッド64aによりフラット配線体部分7を吸着させる。次に、両シリンダ66を上昇作動させて両押圧バー65,65を各貫通孔62aから上方に突出させるようにする。これにより、図9に示すように、上記各押圧バー65により各連結片部12及びこの各連結片部65を挟む部分が上方に曲げられる結果、各非打抜き部11に引き裂き力が作用して各非打抜き部11が実線から一点鎖線で示すように破断する。そして、各押圧バー65を下動させて元の没入位置(図8に示す位置)に復元させる一方、上盤61を各吸着手段64に吸着されたフラット配線体部分7と共に所定の収納位置まで平行移動させる。すなわち、上記上盤61を上方に平行移動させ、次に、その上盤61を製造ラインLの側方に平行移動させ、最後に、この側方位置に配設された図示省略の収納容器等の上まで上記上番61を下動させて吸引用負圧の供給を停止してフラット配線体部分7を離す。これにより、製品としてのフラット配線体Fを順次、整然と積層された状態に収納することができる。
【0028】
上記の非打抜き部11の破断の際、これら各連結片部12や各非打抜き部11等を含む領域の周囲が環状の押さえ面63aにより位置固定されているため、上記各押圧バー65による押圧力を他のフラット配線体部分7等に及ぼすことがなく、これらフラット配線体部分7に損傷を与えるおそれはない。
【0029】
しかも、テープ状積層体4には各連結片部12を区画する一対の直交補助切れ目10a,10aの他に、一対の平行補助切れ目10b,10bをも形成しているため、上記各押圧バー65による各連結片部12への押圧の際に、各連結片部12の両側部分も自由に屈曲して各連結片部12以外に対し上記押圧力による影響が及ぶことを確実に防止することができる上、各押圧バー65に対するテープ状積層体4の相対位置がその幅方向に多少位置ずれしても各押圧バー65の押圧による悪影響を防止した状態で各非打抜き部11の破断を確実に行うことができる。加えて、上記各一対の直交補助切れ目10a,10aによって各連結片部12がテープ状積層体4の長手方向(走行方向)に、ある長さだけ延びているため、上記各押圧バー65に対するテープ状積層体4の相対位置が上記走行方向に多少位置ずれしても、上記各押圧バー65により各非打抜き部11を確実に破断させることができる。従って、製品回収手段60と、打抜き工程P50後のテープ状積層体4との相対位置決めをそれ程厳密に行わなくても、各非打抜き部11の破断を確実に行うことができる。すなわち、上記各一対の直交補助切れ目10a,10aや各一対の平行補助切れ目10b,10bの延長寸法を調整することにより、上記の相対位置決め精度を比較的低いものでも本製品工程P60を行うことができ、高精度位置決めのための特別な構成を省略することができる。
【0030】
<他の実施形態>
なお、本発明は上記実施形態に限定されるものではなく、その他種々の実施形態を包含するものである。すなわち、上記実施形態では、非打抜き部11を主切れ目9に沿って互いに離れた位置に2つ設けているが、これに限らず、回路パターン2の形状,大きさ等に応じて1つのみ設けても、または、3つ以上設けてもよい。すなわち、主切れ目9により区画分離されたフラット配線体部分7をテープ状積層体4に対しそのテープ状積層体4を搬送しても位置ずれしない程度に保持しえればよい。また、これらの場合、上記非打抜き部11の数に応じて押圧バー65の数を定めればよい。そして、回路パターンの種々の形状及びこれに対する非打抜き部の配置等に対応して押さえ盤63の保持部が形成された種々の上盤を用意しておけば、製造する回路パターン等の変更に応じて上盤を交換するだけで製造ラインを容易かつ迅速に構成することができる。
【0031】
また、上記実施形態では、各一対の補助切れ目10,10を一対の直交補助切れ目部10aと一対の平行補助切れ目部10bとで構成しているが、これに限らず、少なくとも一対の直交補助切れ目部だけで一対の補助切れ目を構成してもよい。この場合、押圧バーの長さをその一対の直交補助切れ目部間の連結片部の幅と同等もしくはそれよりも短く設定するのが好ましい。
【0032】
さらに、一対の補助切れ目として、図7等に示すもの以外にも種々の形態を採用してもよい。例えば、図10に示すように主切れ目9の両側部位9a,9aの外側位置から一対の直交補助切れ目部10a′,10a′が出発し、その各先端から互いに相対向する側に一対の平行補助切れ目部10b′,10b′を延ばして、一対の補助切れ目10′,10′を構成してもよい。
【0033】
【発明の効果】
以上説明したように、請求項1記載の発明におけるフラット配線体の製造方法によれば、フラット配線体部分を非打抜き部でテープ残部側につなげて脱落したり位置ずれしたりすることなく次工程まで確実に搬送することができる。そして、製品回収工程において、押圧バーによる押圧により非打抜き部を容易に引張破断させてフラット配線体部分を所定配置のままテープ状積層体から完全に分離させることができる。このため、製品としてのフラット配線体を所定配置のまま確実に回収することができる。しかも、上記破断の際に、上記押圧バーの押圧により非打抜き部へ引張力を有効に作用させることができる上、その押圧の影響を製品となるフラット配線体部分に及ぼすことを確実に防止することができる。
【0034】
請求項2記載の発明によれば、請求項1記載の発明による効果に加えて、押圧バーによる押圧力をより確実に連結片部にのみ作用させることができる上、非打抜き部の破断をより容易に行うことができる。
【0035】
請求項3記載の発明によれば、請求項2記載の発明による効果に加え、製品回収工程において、テープ状積層体と押圧バーとの相対位置が多少ずれても支障なく非打抜き部の破断を確実に行うことができる。
【0036】
請求項4記載の発明によれば、請求項1または請求項2記載の発明による効果に加えて、外形打抜き機による1度の打抜きにより非打抜き部を残した主切れ目と、補助切れ目とを同時に形成することができ、効率化を図ることができる。
【0037】
また、請求項5記載の発明によれば、請求項1記載の発明による効果に加えて、包囲線に沿った全周部分が弾性押圧により非打抜き部の周囲近傍を確実に位置固定することができる上に、その押圧によるフラット配線体部分への損傷のおそれを確実に解消することができる。
【0038】
さらに、請求項6記載の発明によれば、請求項1記載の発明による効果に加えて、製品としてのフラット配線体を順次整然と積層状態もしくは並列状態にして収納させることができる。

BACKGROUND OF THE INVENTION
The present invention is a method for manufacturing a flat wiring body that is used as an electric wiring material and in which a wiring pattern made of one or two or more narrow conductor foils is sandwiched between a pair of insulating films. The present invention relates to a method for manufacturing a flat wiring body obtained by punching out a predetermined portion from a series of tape-like laminates running on a manufacturing line.
[0002]
[Prior art]
As a method for manufacturing such a flat wiring body, a method proposed by the present applicant in Japanese Patent Laid-Open No. 6-68722 is known. The schematic manufacturing process of the flat wiring body will be described based on the example shown in FIG. 1. First, the copper foil U adheres onto the carrier tape 1 that travels along the production line L and has a relatively thick and adhesive layer. Only the copper foil U is sequentially punched along the shape of a predetermined wiring pattern (half-cut process P1). Thereafter, the remaining copper foil portion Ur which is the remaining material portion excluding the wiring pattern 2 is removed (remaining material portion removing step P2), and only the wiring pattern 2 is left on the carrier tape 1 in a state where it is adhered. Next, the wiring pattern 2 is transferred from the carrier tape 1 to the tape-like insulating film 3 having a relatively thin thickness and having an adhesive layer, and the carrier tape 1 is peeled off (transfer process P3). Is in a state where one side is bonded onto the insulating film 3 (see the broken portion on the right side of FIG. 2). Then, another insulating film 3 is laminated and bonded to the upper surface of the wiring pattern portions 2, 2,... To form a tape-like laminate 4 (lamination step P4). By punching with the outer shape punching machine 5, a cut 6 (see FIG. 3) is made in the entire circumference along the outer peripheral shape of the wiring pattern 2 for each unit of the wiring pattern portion 2 (outer shape punching step P5). The tape-like laminate 4 is separated and divided into a flat wiring body portion 7 and a remaining tape portion 8 other than this. After being transported to the next process on the production line L in this state, the flat wiring body portion 7 is taken out from the tape-like laminate 4 (product recovery process P6), whereby a wiring pattern is obtained as shown in FIG. The flat wiring body F as a product in which the upper and lower surfaces 2 are bonded to each other by the adhesive layers 3a between the pair of insulating films 3 and 3 and formed into a predetermined outer shape is collected and stored.
[0003]
2 and 3 exemplify a circuit pattern 2 constituted by three narrow conductor foils 21, 21, and 21, and FIG. 3 shows a greatly exaggerated thickness. .
[0004]
[Problems to be solved by the invention]
However, in the above-described conventional flat wiring body manufacturing method, the entire circumference of the flat wiring body portion 7 is punched in the outer shape punching process P5, so that it is conveyed on the production line from the outer shape punching process P5 to the product recovery process P6. There is a risk that the flat wiring body portion 7 may fall off from the tape-like laminate or be dragged in a misaligned state even if it does not fall off. When such a situation occurs, the positions of the flat wiring body parts 7 that are originally arranged on the tape-like laminate 4 at regular intervals and conveyed to the product recovery step P6 are dispersed, and the product F itself is recovered. Or the collected product F is difficult to align and store in a predetermined position.
[0005]
This invention is made | formed in view of such a situation, The place made into the objective is to collect | recover the flat wiring body after outline punching reliably.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 is a tape-like laminate in which a circuit pattern made of a conductive foil is sequentially interposed between a pair of tape-like insulating films and travels downstream along a production line. The tape-shaped laminate is separated into a flat wiring body portion and a tape remaining portion excluding the flat wiring body portion by an outer shape punching process in which an outer shape punching machine punches the tape-shaped laminate along the outer peripheral shape larger than the circuit pattern. A flat in which a loop-shaped main cut is formed, followed by a product recovery step of recovering a flat wiring body portion from the tape-shaped laminate in which the main cut is formed on the production line downstream of the outer shape punching machine. The method for manufacturing a wiring body is intended. In this outer shape punching step, when punching by the outer shape punching machine, at least one portion along the main cut leaves a non-punched portion that does not form a cut across a minute dimension, while the main punches on both sides sandwiching the non-punched portion are left. By forming a pair of auxiliary cuts extending from the cut to the tape remaining side, one end side is continuous only between the flat wiring body portion and the non-punched portion between the pair of auxiliary cuts, and the other end side is larger than the non-punched portion. A connecting piece portion that is continuous with the remaining tape portion in size is defined. In the product recovery step, the tape-like laminate is sandwiched from the front and back along the encircling line surrounding the non-punched portion, the main cuts on both sides sandwiching the non-punched portion, and the pair of auxiliary cuts from the outside. The portion along the surrounding line is held at the same plane position, and the non-punched portion is broken by pressing the connecting piece portion with a pressing bar from one side of the front and back in this held state.
[0007]
In the case of the above configuration, in the outer shape punching process, a main cut is formed in a state where a non-punched portion of a minute dimension is left on a part of the flat wiring body portion instead of the entire circumference, and the main cut is continuously formed. Thus, a pair of auxiliary cuts are formed, whereby the connecting piece portion connected by the flat wiring body portion side and the non-punched portion is partitioned and formed on the tape remaining portion side. For this reason, the flat wiring body portion is connected to the tape remaining portion side at the non-punched portion and is reliably conveyed to the next step without falling off or being displaced. And, in the product recovery process, when the connecting piece portion is pressed by the pressing bar, the connecting piece portion is bent away from the tape remaining portion at the pair of auxiliary cut positions to the front and back sides, and the non-punched portion on one end side, A tensile force acts on the tape remaining part on the other end side. And since the non-punched portion has a minute size, a pair of insulating films having a small width constituting the non-punched portion easily causes a tensile break, and the flat wiring body portion and the connecting piece portion are separated from each other, Thereby, the said flat wiring body part is isolate | separated completely from a tape-shaped laminated body. At this time, the tape-like laminate is sandwiched from the front and back so as to surround the non-punched portion, the main cuts on both sides thereof, and the pair of auxiliary cuts from the outside, and the inside is kept at the same plane position, so In addition to effectively pressing the connecting piece by the pressing bar, it is possible to reliably prevent the influence of the pressing from being exerted on the flat wiring body portion as a product.
[0008]
The invention according to claim 2 is a pair of orthogonal auxiliary cuts extending in a direction substantially perpendicular to the extending direction of each main cut from the main cuts on both sides sandwiching the non-punched portion, in the outer shape punching process according to claim 1 Then, a pair of parallel auxiliary cuts extending substantially in parallel to the main cut are formed continuously at the ends of the both orthogonal auxiliary cuts. Then, in the product recovery step, the surrounding line is set so as to surround the non-punched portion, the main cuts on both sides sandwiching the non-punched portion, the pair of orthogonal auxiliary cuts, and the pair of parallel auxiliary cuts from the outside. The pressing bar presses the connecting piece at the intermediate position of the pair of orthogonal auxiliary cuts.
[0009]
In the case of the above configuration, as a pair of auxiliary cuts in the outer shape punching process, a pair of orthogonal auxiliary cuts and a pair of parallel auxiliary cuts continuous from the tip of each orthogonal auxiliary cut are formed. The pressing force can be applied only more reliably to the connecting piece portion, and the non-punched portion can be more easily broken.
[0010]
According to a third aspect of the present invention, in the second aspect of the invention, the pair of parallel auxiliary cuts are formed so as to extend from the tips of the orthogonal auxiliary cuts to opposite sides.
[0011]
In the case of the above configuration, since the pair of parallel auxiliary cuts extend on opposite sides, a portion sandwiched between each parallel auxiliary cut and the main cut on each side sandwiching the non-punched portion is connected by each orthogonal auxiliary cut. Separated from one part. For this reason, there will be a portion that can be moved freely on both sides of the connecting piece portion and can be moved freely even if it is pressed by the pressing bar. Even if a pressing force is applied to both side portions, unnecessary tensile force is not applied to the remaining tape portion. Therefore, in the product recovery process, even if the relative position between the tape-shaped laminate and the pressing bar is slightly shifted, the non-punched portion can be broken without any problem.
[0012]
According to a fourth aspect of the present invention, in the outer shape punching step of the first or second aspect of the present invention, the main cut and the auxiliary cut are simultaneously formed by punching with an outer punching machine.
[0013]
In the case of the above configuration, the main cut leaving the non-punched portion and the auxiliary cut are simultaneously formed by one-time punching by the external punching machine, and the efficiency is improved.
[0014]
According to a fifth aspect of the present invention, in the product recovery step of the first aspect, the cylindrical elastic member having a tip peripheral surface extending along the encircling line is at least relative to the pressing bar with the tape-shaped laminate interposed therebetween. It arrange | positions to the side which faces, and the front-end | tip peripheral surface of the cylindrical elastic member is pressed on the said tape-shaped laminated body.
[0015]
In the case of the above configuration, by pressing the front peripheral surface of the cylindrical elastic member, the entire peripheral portion along the surrounding line is elastically pressed, and the portion along the surrounding line is securely fixed in position. The possibility of damage to the flat wiring body portion due to the pressing is surely eliminated.
[0016]
Further, the invention according to claim 6 is the product recovery step according to claim 1, wherein the flat wiring body portion is sucked and held by the sucking means, and the non-punched portion is broken, and then the sucking means is moved in parallel. The flat wiring body part is separated from the tape-like laminate and collected.
[0017]
In the case of the above configuration, by separating and collecting the flat wiring body portion by parallel movement of the suction means from the tape-shaped laminated body, it becomes possible to store the flat wiring body as a product in an orderly stacked or parallel state. .
[0018]

[0020]
(Outline punching process P50)
As shown in FIG. 4, the outer shape punching machine 50 is provided with an upper die 52 in which a punching blade 51 constituted by, for example, a biclear blade (bik blade) is protruded downward, and a relatively thick underlay mat on the upper surface. And a lower mold 53. Then, by moving the upper mold 52 downward with the tape-shaped laminated body 4 placed on the upper surface of the lower mold 53, the tape-shaped laminated body 4 is moved from the top to the bottom with the same cut as the shape of the punching blade. It is designed to penetrate.
[0021]
As shown in FIGS. 5 and 6, the shape of the punching blade 51 surrounds the outer periphery of the circuit pattern 2 in a loop shape and separates the tape-like laminate 4 into a flat wiring body portion 7 and a remaining tape remaining portion 8. The main cuts 9 to be partitioned and the auxiliary cuts 10, 10, 10, 10 respectively extending from the main cuts 9 at positions corresponding to both ends of the circuit pattern 2 to the tape remaining part 8 side are formed. Yes. In addition, a minute gap is provided at each of the predetermined positions on both ends of the circuit pattern 2 of the loop-shaped blade corresponding to the main cut 9 of the punching blade 51, whereby the main cut 9 The non-punched portions 11 and 11 having a minute dimension S (for example, 0.5 to 1.0 mm; see FIG. 7), that is, minute portions where no cuts are formed, are left at both ends of each. And each said pair of auxiliary cut | interruption 10,10 is orthogonal to the direction where the both-sides part 9a, 9a is extended from the both-sides part 9a, 9a of the main cut | gap 9 which pinches | interposes each non-punching part 11, respectively, and the tape remaining part 8 side respectively A pair of orthogonal auxiliary cut portions 10a, 10a extending from each other, and a pair of parallel auxiliary cut portions 10b, 10b extending in parallel to and opposite to the side portions 9a, 9a from the orthogonal auxiliary cut portions 10a. Has been. Thereby, between the pair of orthogonal auxiliary cuts 10a, 10a, one end side is continuous with the flat wiring body portion 7 via the non-punched portion 11, and the other end side is significantly larger than the minute dimension S of the non-punched portion 11. A connecting piece portion 12 (see FIG. 7) that is continuous with the tape remaining portion 8 in width is partitioned.
[0022]
In the outer shape punching step P50, the upper die 52 is moved downward to the lower die 53 side with the tape-like laminate 4 interposed therebetween, so that the tape-like laminate 4 is punched with the punching blade 51. The main cut 9 is formed while leaving the non-punched portions 11, 11, and at the same time, the pair of auxiliary cuts 10, 10 are formed so that the connecting piece portions 12 are partitioned at both ends of the main cut 9. .
[0023]
(Product recovery process P60)
The product recovery means 60 is disposed along the production line L at the downstream side of the outer punching machine 50, and a lower board 61 on which the tape-like laminate 4 is placed on the upper surface, and the lower board 61 On the other hand, there is provided an upper board 62 which is opposed to and reciprocally moved in parallel in the vertical direction and the side of the production line L. As shown in FIGS. 6 and 8, the upper board 61 is provided with a pair of pressing boards 63, 63 as a pair of cylindrical elastic members, and a pair of suction means 64, 64. A pair of pressing bars 65, 65 are provided at 62 so as to face each of the pressing plates 63.
[0024]
Each presser plate 63 has a peripheral surface at the front end that serves as a presser surface 63a for the tape-like laminate 4, and is formed into a cylindrical shape by a cushioning elastic material such as foamed resin. Each presser plate 63 is disposed on the upper plate 61 so that the presser surface 63a surrounds the periphery of each connecting piece 12 in the tape-like laminate 4 after the outer shape punching step P50 is completed. Specifically, each pressing surface 63a includes each non-punched portion 11 and both side portions 9a and 9a of the main cut 9 sandwiching each non-punched portion 11, and each pair of orthogonal auxiliary cut portions 10a and 10a. The tape-like laminate 4 is pressed against the lower plate 62 so as to surround the pair of parallel auxiliary cut portions 10b, 10b from the outside so as to temporarily fix the periphery of the connecting piece portions 12. It has become.
[0025]
Each of the suction means 64 includes a suction pad 64a and a pipe 64b for supplying a suction negative pressure to the suction pad 64a. By supplying the suction negative pressure from the pipe 64b, the flat wiring body portion is provided. 7 is sucked into the suction pad 64a.
[0026]
Each of the pressing bars 65 is fixed to the upper end of a rod 66a of a cylinder 66 (see FIG. 8), and is disposed so as to be able to protrude and retract from the upper end opening of the through hole 62a of the lower board 62 by raising and lowering the rod 66a. Here, the cylinder 66 is attached to the lower surface of the lower board 62 via a bracket 67, and a stopper 68 is interposed between the pressing bar 65 and the rod 66a so as to be at the lower end opening edge of the through hole 62a. By abutting, further upward movement of the pressing bar 65 is prevented. And each said press bar 65 is longer than the width | variety of each connection piece part 12, and the length of the both-sides parts 9a and 9a of the main cut 9 which pinches | interposes each non-punching part 11 (refer FIG. 7), or a pair The parallel auxiliary cuts 10b and 10b have a length that does not become longer than the shorter one of the arrangement lengths over the parallel auxiliary cuts 10b. It arrange | positions so that each non-punching part 11 may be fractured | ruptured. That is, each pressing bar 65 is at least an intermediate position between both ends of each connecting piece 12 with respect to each connecting piece 12 in a state of being pressed by the pressing surface 63a of each holding plate 63, preferably It is positioned so as to cross a substantially central position between both ends.
[0027]
In this product recovery step P60, the tape-like laminate 4 sent from the outer punching machine 50 to the product recovery means 60 is positioned and stopped, and the upper board 61 is moved downward with respect to the tape-like laminate 4. In addition to pressing with the pressing surfaces 63a of the pressing plates 63, 63 (see the one-dot chain line in FIG. 8), the flat wiring body portion 7 is sucked by the suction pads 64a of both the suctions 64, 64. Next, both cylinders 66 are moved up so that both pressing bars 65, 65 protrude upward from the respective through holes 62a. As a result, as shown in FIG. 9, each connecting piece 12 and the portion sandwiching each connecting piece 65 are bent upward by each pressing bar 65, so that a tearing force acts on each non-punched portion 11. Each non-punched portion 11 is broken as shown by a one-dot chain line from a solid line. Then, each pressing bar 65 is moved down to be restored to the original immersion position (position shown in FIG. 8), while the upper board 61 is brought together with the flat wiring body portion 7 adsorbed by each adsorbing means 64 to a predetermined storage position. Translate. That is, the upper board 61 is translated upward, and then the upper board 61 is translated to the side of the production line L. Finally, a storage container (not shown) disposed at this side position, etc. The upper number 61 is moved down to stop the supply of the negative pressure for suction, and the flat wiring body portion 7 is released. Thereby, the flat wiring body F as a product can be sequentially accommodated in the state laminated | stacked orderly.
[0028]
When the non-punched portion 11 is broken, the periphery of the area including the connecting piece 12 and the non-punched portion 11 is fixed by the annular pressing surface 63a. The pressure is not applied to the other flat wiring body portions 7 and the like, and there is no possibility of damaging these flat wiring body portions 7.
[0029]
Moreover, since the tape-like laminate 4 is also formed with a pair of parallel auxiliary cuts 10b and 10b in addition to the pair of orthogonal auxiliary cuts 10a and 10a that divide each connecting piece portion 12, each of the pressing bars 65 described above. When pressing the connecting piece portions 12 by the above, it is possible to reliably prevent both side portions of the connecting piece portions 12 from being bent freely and exerting influences other than the connecting piece portions 12 due to the pressing force. In addition, even if the relative position of the tape-like laminate 4 with respect to each pressing bar 65 is slightly displaced in the width direction, each non-punched portion 11 is reliably broken in a state in which adverse effects due to pressing of each pressing bar 65 are prevented. It can be carried out. In addition, each connecting piece 12 extends by a certain length in the longitudinal direction (running direction) of the tape-like laminate 4 by the pair of orthogonal auxiliary cuts 10a, 10a. Even if the relative position of the laminated body 4 is slightly displaced in the traveling direction, the non-punched portions 11 can be reliably broken by the pressing bars 65. Accordingly, the non-punched portions 11 can be reliably broken without the relative positioning of the product collecting means 60 and the tape-like laminate 4 after the punching step P50 being performed so strictly. That is, by adjusting the extension dimension of each pair of orthogonal auxiliary cuts 10a, 10a and each pair of parallel auxiliary cuts 10b, 10b, the product process P60 can be performed even if the relative positioning accuracy is relatively low. And a special configuration for high-precision positioning can be omitted.
[0030]
<Other embodiments>
In addition, this invention is not limited to the said embodiment, Various other embodiments are included. That is, in the above-described embodiment, the two non-punched portions 11 are provided at positions separated from each other along the main cut line 9, but not limited to this, only one according to the shape, size, etc. of the circuit pattern 2. It may be provided, or three or more may be provided. That is, the flat wiring body portion 7 partitioned and separated by the main cut 9 may be held to such an extent that the tape-like laminated body 4 is not displaced even when the tape-like laminated body 4 is conveyed. In these cases, the number of the pressing bars 65 may be determined according to the number of the non-punched portions 11. If various upper boards in which holding parts of the presser board 63 are formed corresponding to various shapes of circuit patterns and the arrangement of non-punched parts with respect thereto, etc., the circuit pattern to be manufactured can be changed. Accordingly, the production line can be configured easily and quickly by simply replacing the upper board.
[0031]
Moreover, in the said embodiment, although each pair of auxiliary cuts 10 and 10 are comprised by a pair of orthogonal auxiliary cut part 10a and a pair of parallel auxiliary cut part 10b, not only this but at least a pair of orthogonal auxiliary cut line You may comprise a pair of auxiliary cut | interruption only by a part. In this case, it is preferable to set the length of the pressing bar to be equal to or shorter than the width of the connecting piece between the pair of orthogonal auxiliary cuts.
[0032]
Furthermore, as the pair of auxiliary cuts, various forms other than those shown in FIG. For example, as shown in FIG. 10, a pair of orthogonal auxiliary cut portions 10a 'and 10a' start from the outer positions of both side portions 9a and 9a of the main cut 9, and a pair of parallel auxiliary members are arranged on opposite sides from their respective tips. The cut portions 10b 'and 10b' may be extended to form a pair of auxiliary cuts 10 'and 10'.
[0033]
