【発明の属する技術分野】
本発明は、一般に自動車用のブレーキ、フューエル、クラッチ、エアー等、または他の内燃機関における燃料供給路として多用される端末成形された管（以下「端末成形管」と称する）の製造装置、特に管の連続製造装置に関するものである。
【０００２】
【従来の技術】
従来、この種の端末成形管は図１１にその全体形状を例示するように、内部に流通路１０−１を有する薄肉細径管体１０の接続端部に、ダブルまたはシングルにフレア加工された接続頭部１０−２を有し、当該管体に管継ナット１１が外嵌された構造となっている。この端末成形管の製造方法としては、定寸に切断された内部に流通路１０−１を有する薄肉細径管体１０に管継ナット１１を挿入した後、端末をプレス加工したダブルフレア形状の接続頭部１０−２を成形する方法が一般的であるが、従来は薄肉細径管体１０の定寸切断、管継ナット１１の挿入および端末のプレス加工をそれぞれ別工程で行っている。すなわち、まず切断工程で所望長さの管体を定寸に切断し、続いてこの管体をナット挿入工程に送り管継ナット１１を挿入し、しかる後このナット付き管体をプレス加工工程に送り、管端末にダブルフレア等の接続頭部１０−２を成形している。
【０００３】
【発明が解決しようとする課題】
従来の端末成形管の製造方法は上記のごとく、管体の切断およびプレス加工、管継ナットの挿入をそれぞれ別工程で行っているため、生産性が低いという欠点があった。また、各工程への材料の搬送、管体の切断、プレス加工、およびナット挿入作業等は人手を必要とするため、多くの作業員を要するのみならず時間的ロスも大きく、作業能率が低いという欠点があった。
【０００４】
本発明は、このような従来の実状に鑑みてなされたものであり、従来別工程で行っていた管体の切断、プレス加工および管継ナットの挿入等の全行程を１台の装置で自動的かつ連続的に行って一工程タクトで生産することができる高能率、高生産性の端末成形管製造装置を提供しようとするものである。
【０００５】
【課題を解決するための手段】
本発明に係る端末成形管の製造装置は、薄肉細径管体の接続両端部に接続頭部を有し、当該管体に管継ナットが外嵌された定寸長さの端末成形された管の製造装置であって、長尺の管体を一本ずつ取出し管軸方向に送給する管体供給装置と、前記管体供給装置側より管軸方向に順に、前記管体供給装置より送給される管体を定寸切断する管体定寸切断機、管体に２個１対の管継ナットを同時に外挿する管継ナット供給機および先端側管体端末に前記接続頭部を成形するための第１端末プレス加工機が直列して配設され、前記管体供給装置より送給される管体が前記管体定寸切断機を介して前記管継ナット供給機を通過する際に２個１対の管継ナットが同時に外挿されて、前記第１端末プレス加工機の所定の位置決め位置まで管体が送給され、前記第１端末プレス加工機にて先端部を位置決めされた管体が前記管体定寸切断機にて定寸切断されるともに、前記第１端末プレス加工機にて管体の先端側管体端末に前記接続頭部が成形される仕組みとなし、前記第１端末プレス加工機での前記接続頭部の加工とともに前記管体定寸切断機にて定寸切断された管体を管軸と直角方向に搬送する管体横送り搬送装置と、前記管体横送り搬送装置の搬出側の側端部に位置し前記搬送装置により横送りされた管体の後端側端部に前記と同じ接続頭部を成形するための第２端末プレス加工機、および前記第２端末プレス加工機と相対向する位置に配設されたパイプ位置決め装置を備え、前記管体横送り搬送装置にて搬送される管体の後端側を前記パイプ位置決め装置と前記第２端末プレス加工機と協動して位置決めするとともに第２端末プレス加工機にて当該管体の後端側端部に前記接続頭部が成形される仕組みとなし、前記管体横送り搬送装置の搬出側に連設配置され前記第１端末プレス加工機および第２端末プレス加工機での加工後の前記管継ナット付き管体を搬出する製品搬出装置と、前記製品搬出装置より搬出された管体を回収する製品回収ホッパーを備え、前記長尺の管体の供給、定寸切断、管継ぎナットの２個同時外挿、管体の両端末のプレス加工、製品の搬送および搬出が自動的にかつ前記の各動作が連続して行われる機構となしたことを特徴とするものである。
【０００６】
内部に流通路を有する薄肉細径管を一本ずつ取出し管軸方向に送給する管体供給装置は、素管製造工程で所望の長さに製造された長尺の薄肉細径管をストックしておき、モータ駆動される送りローラにより該管体を一本ずつ管軸方向に送給する機能を備えている。
【０００７】
管体定寸切断機は、管体を固定した状態でメタルソーにて自動切断する方式となしたもので、この種の切断機としては例えば管体を流体圧シリンダーにて固定するクランプ機構とモータ駆動式の円形のメタルソーとから構成され、クランプされた管体に対しメタルソーを水平移動させて切断する方式のものがある。この管体定寸切断機は、前記管体供給装置に隣設される。
【０００８】
管継ナット供給機は、管継ナットを間欠的に管軸線上に供給する機構を備えており、その構造は例えば専用のボックス形シューター内に段積み状に収納された管継ナットをだるま落し式で押出し、その押出された管継ナットを流体圧シリンダー等にて管軸と直角方向に一定ストローク前後動する受金具に嵌合させて前記管体の管軸線上に位置させる方式のものを用いることができる。この管継ナット供給機は、前記管体定寸切断機に隣設される。
【０００９】
管体の先端側端末に前記接続頭部を成形するための第１端末プレス加工機は、前記管体供給装置により送給されてきた管体を定寸切断するための位置決め用ストッパーを有し、このストッパーにて管体を一旦所定の位置に停止させた後、前記管体定寸切断機による切断と同時にプレス加工にて接続頭部の成形が行われる仕組みとなっている。接続頭部の成形方法としては、管体をチャックに保持せしめた状態で、頭部成形用の成形パンチを強圧縮して挫屈成形する方法を用いることができる。この第１端末プレス加工機は、管体の切断寸法の変化に対応できるように管軸方向に移動可能となっている。
【００１０】
前記プレス加工後の管体を管軸と直角方向に搬送する管体横送り搬送装置は、例えば管体と直角方向に配置した相平行する一対のサイドガイドに流体圧シリンダー等にて一定ストローク前後動する搬送プレートを装着し、このプレートに所定の間隔を隔てて左右２個ずつ取付けた垂直シリンダーに管体受けブロックを取付け、この昇降式の管体受けブロックにて前記プレス加工後の管体を一本ずつ支持して順次横送りする方式のものを用いることができる。
【００１１】
前記管体横送り搬送装置の側端に位置し該装置上にて横送りされた管体の後端側端部に前記と同じ接続頭部を成形するための第２端末プレス加工機は、前記第１端末プレス加工機と反対側に位置するが、その構造は第１端末プレス加工機と同様、横送りされきた管体の位置決め用ストッパーを有し、該プレス加工機と相対向する位置に配置したパイプ位置決め装置により管体の位置決めを行った後、プレス加工にて接続頭部の成形が行われる仕組みとなっている。この第２端末プレス加工機は管体の寸法の変動に対応させる必要がないため固定式となっている。パイプ位置決め装置は、第２端末プレス加工機と同軸線上に配置され、その構造は例えば流体圧シリンダーの先端に設けた管体押圧プレートにて管体を管軸方向に移動させる方式のものを用いることができる。なお、このパイプ位置決め装置も管体の切断寸法の変化に対応できるように前記第１端末プレス加工機と同様に管軸方向に移動可能となす。
【００１２】
製品の搬出装置は、前記管体横送り搬送装置のサイドガイドの端末に前記第２端末プレス加工機と同軸線上に配置され、その構造は前記サイドガイドの端末に流体圧シリンダーにて搬出側に傾動可能に配置した垂直シリンダーに管体受けブロックを取付け、この昇降式の管体受けブロックにてプレス加工後の管体（製品）を一本ずつ支持するとともに、該垂直シリンダーを搬出側に傾斜させて管体受けブロックより管体を前記サイドガイドの端末に設けた傾斜ガイド上に載せ、該傾斜ガイド上を転動させて製品回収ホッパー上に落下させる方式となしたものを用いることができる。製品回収ホッパーは例えば細幅の金属板をＵ字形に折曲げて形成したプレートを前記傾斜ガイドの端末に間隔設置して構成することができる。なお、この製品搬出装置は、接続頭部の成形寸法に狂いが生じて製品が不良品となった場合に、該不良品を製品と分けて回収するための切替ゲートを備えている。
【００１３】
すなわち、本発明装置は、管体供給装置により一本ずつ送給される管体の先端部が管体定寸切断機にて切断（頭切）が行われ、続いてその管軸方向送給ライン上で管継ナットが挿入され、該管体が第１端末プレス加工機まで移動すると、位置決め用ストッパーにて管体を一旦所定の位置に停止させた後、管体定寸切断機による切断と同時にプレス加工にて接続頭部の成形が行われ、続いて、管体横送り搬送装置にて当該管体を第２端末プレス加工機の位置まで横送りし、その位置でパイプ位置決め装置による管体の位置決めが行われると同時にプレス加工が施されて後端側の接続頭部成形が行われ、しかる後搬出装置にて管体を排出し製品回収ホッパーに回収されるように構成されたもので、管体が第１端末プレス加工機より離れると同時に次の管体が供給されて上記と同様の動作が連続して繰返される仕組みとなっている。
【００１４】

【００２０】
管継ナット供給機３は、図２、図４、図５に示すごとく、管継ナット１１を段積み状に収納するボックス形シューター３−１と、このシューターよりだるま落し式で押出された管継ナット１１を受けて管体１０の管軸線上に位置させるナットセッティング装置３−２とから構成され、ボックス形シューター３−１は、ナットセッティング装置３−２の上方に該装置と分離させて立設され、２個一対の管継ナット１１がだるま落し式で押出されるように段積み状に収納される構造となっている。ナットセッティング装置３−２は、管軸と直角方向に配置した断面凹形の枠体３−２１内に敷設したレール３−２２上に、ナット嵌合凹部３−２４を有するナット受け３−２３が前記レールに摺動可能に凹凸嵌合するガイド３−２５を介して管軸と直角方向に前後動可能に載置され、その背面側に設置した供給シリンダー３−２６にてナット受け３−２３を前後動させる機構となっている。なお、３−２７は枠体３−２１の管軸線上に設けられている管体の通過溝、３−２８は管体挿入ガイドである。

【００２６】
パイプ位置決め装置７は、上記第２端末プレス加工機６により管体１０の後端側端末に接続頭部１０−２を成形する際に、そのプレスライン上で管体の位置決めを行うための装置であり、その構造は第１端末プレス加工機４側のベースプレート７−１上に第２端末プレス加工機６と相対向する位置に水平に設置した位置決め用シリンダー７−２のロッド先端に管体押圧板７−３を取付けた構成となし、前記管体横送り搬送装置５により管軸と直角方向に搬送されて第２端末プレス加工機６のプレスライン上に位置した管体の先端側を位置決め用シリンダー７−２にて管軸方向に押動し、第２端末プレス加工機６側の位置決め用ストッパー６−４に管後端を当接させて位置決めを行うものである。
【００２７】
製品搬出装置８は、図８、図９、図１０に示すごとく前記管体横送り搬送装置５の水平バー５−１、５−２の先端部（搬出側）に垂設したブラケット８−１、８−２に、基端を搬出方向に傾動可能に垂直に軸着され、かつその上端部を同水平バー５−１、５−２に水平に横設した搬出用水平シリンダー８−５、８−６にて支持され、各ロッドに管体１０を下方から支持するＶブロック８−７、８−８が取付けられた搬出用垂直シリンダー８−３、８−４と、同水平バー５−１、５−２の先端に取付けられ、前記ブラケット８−１、８−２に横設した水平バー８−９、８−１０に垂直に取付けた支持板８−１１、８−１２に下端部を取着された傾斜ガイド８−１３、８−１４と、さらに前記水平バー８−９、８−１０の先端部に垂直に支持された不良品排出用垂直シリンダー８−１５、８−１６に取付けられ、前記傾斜ガイド８−１３、８−１４と同一勾配を有する切替ゲート８−１７、８−１８とから構成され、前記切替ゲートの出側に製品回収ホッパー９が取付けられている。製品回収ホッパー９は、細幅の金属板をＵ字形に折曲げて形成したプレート９−１、９−２とで構成され、前記水平バー８−９、８−１０の先端部に立設した垂直支柱９−３、９−４に取着されている。
【００２８】
すなわち、この製品搬出装置８は、第２端末プレス加工機６により接続頭部成形が終了した管体１０を搬出用垂直シリンダー８−３、８−４にて一旦上方に持上げ、その状態で搬出用水平シリンダー８−５、８−６にて前記搬出用垂直シリンダー８−３、８−４を搬出側に倒して管体１０をＶブロック８−７、８−８より離脱させて傾斜ガイド８−１３、８−１４上に移載する方式であり、傾斜ガイド８−１３、８−１４上に移載された製品は該傾斜ガイドおよび切替ゲート８−１７、８−１８上を転動落下して製品回収ホッパー９に回収される。なお、接続頭部の成形寸法に狂いが生じて製品が不良品となった場合は、不良品排出用垂直シリンダー８−１５、８−１６を上方に作動させて切替ゲート８−１７、８−１８を上昇させて傾斜ガイド８−１３、８−１４と製品回収ホッパー９間を分断することにより、不良品は傾斜ガイド８−１３、８−１４の終端より水平バー８−９、８−１０上に落下するようになっている。
【００２９】
上記構成の端末成形管製造装置において、管体供給装置１により一本ずつ管軸方向に送給される長尺の管体１０は、まず定寸切断機２にて頭切が行われ、続いてその管軸方向送給ライン上で管継ナット供給機３によりセットされている管継ナットが挿入され、その後該管体が第１端末プレス加工機４まで移動すると、位置決め用ストッパー４−４にて管体を一旦所定の位置に停止させた後、管体定寸切断機２による切断と同時に第１端末プレス加工機４にて先端側端末に接続頭部の成形が行われる。この第１端末プレス加工機４によるプレス加工が終了すると、管体横送り搬送装置５にて当該管体を第２端末プレス加工機６の位置まで横送りし、その位置でパイプ位置決め装置７による管体の位置決めが行われると同時に第２端末プレス加工機６にてプレス加工が施されて後端側の接続頭部成形が行われる。このようにして両管端に接続頭部が成形された製品は、製品搬出装置８にて搬出され製品回収ホッパー９に回収される。なお、管体が第１端末プレス加工機より離れると同時に、残った管体が管軸方向にさらに送られて同様の動作を連続して繰返すが、管体の長さが所定の長さより短い場合には次の管体が供給されて上記と同様の動作が連続して繰返される。一方、不良品が生じた場合は、製品搬出装置８の切替ゲート８−１７、８−１８を作動させて当該不良品を製品とは別に回収する。
【００３０】
上記した本発明装置における管体供給装置１、管体定寸切断機２、管継ナット供給機３、第１端末プレス加工機４、管体横送り搬送装置５、第２端末プレス加工機６、パイプ位置決め装置７、製品搬出装置８の作動は、すべてシーケンス制御により自動的にかつ連続して行われる仕組みとなっていることはいうまでもない。
【００３１】
【発明の効果】
以上説明したごとく、本発明装置は、管体供給装置により一本ずつ送給される長尺の管体をその管軸方向送給ライン上で定寸切断されるとともに管継ナットが挿入され、管体定寸切断機による切断と同時に第１端末プレス加工機にて先端側の接続頭部の成形が行われ、続いて、管体横送り搬送装置にて当該管体が第２端末プレス加工機の位置まで横送りされ、第２端末プレス加工機にて後端側の接続頭部の成形が行われ、しかる後搬出装置にて製品回収ホッパーに回収されるように構成され、管体の定寸切断、管継ナットの挿入、端末プレス加工、管体の搬送および製品回収等の全行程を１台の装置で自動的かつ連続的に行って一工程タクトで生産することができるので、端末成形管を高能率、高生産性で製造することができるという大なる効果を奏する。
