Abstract
Description
このスライドロック装置においては、ヘリカルギヤの歯幅方向に並べて3組のロックユニットを設け、ロックユニットの下端側にヘリカルギヤのギヤ歯間の谷部に係合可能な係合爪を設け、その係合爪をロックユニット内に設けた油圧式アクチュエータで進退駆動する。スライドをロックする際、3組のロックユニットを同時に駆動して3つの係合爪を進出側へ駆動し、何れか1つの係合爪をギヤ歯間の谷部に係合させ、鋼球を含むボールロック機構により係合爪をロックすることにより、ヘリカルギヤをロック状態にしてスライドをロックする。
この安全ロック機構においては、プレスの軸部材を貫通させた静止部材が本体フレームに固定され、この静止部材に形成した複数の保持孔に複数のロックピンが移動可能に装着されている。この静止部材に軸方向の外側から対向する被ロック部材が軸部材に固定され、この被ロック部材の外周近傍部には複数のロックピンの内周側半分を受容する複数の円弧状のリセスが形成され、これらリセスの周方向端部にはロックピンを受け止め可能な複数のロック用歯部が形成されている。
しかも、複数のロックピンを後退位置にロックするロック機構や進出位置にロックするロック機構を備えていない。そのため、オペレータの誤操作又は制御系の故障等により環状流体圧シリンダが誤動作すると、安全ロック機構が誤動作し、軸部材及びスライドをロック状態から誤ってアンロック状態に切換えたり、その反対に、アンロック状態から誤ってロック状態に切換えたりする虞がある。
(1)前記複数の保持孔と反対側からフランジ部に対向し且つ本体部材に固定された補助本体部材と、前記複数のピン部材の先端側部分を挿入可能に前記補助本体部材に形成された複数の支持孔とを設け、前記ピン部材が進出位置に移動したとき、前記導入孔を貫通したピン部材の先端側部分が対応する前記支持孔に貫通状に挿入されるように構成する。
(3)前記(2)において、前記第2ロック部材が前記補助本体部材のうちの前記フランジ部材と反対側の端面の近傍位置に配置される。
(4)前記第1ロック部材の位置がロック位置かアンロック位置かを検知する第1検知手段と、前記第2ロック部材の位置がロック位置かアンロック位置かを検知する第2検知手段とを設ける。
(6)前記(5)において、前記流体圧シリンダは前記ピストン部材を進出させる為の往動流体室と前記ピストン部材を後退させる為の復動流体室とを有し、複数の流体圧シリンダの複数の往動流体室は流体圧供給/排出用の共通の1つの第1ポートに接続され、複数の流体圧シリンダの複数の復動流体室は流体圧供給/排出用の共通の1つの第2ポートに接続される。
(8)前記第2駆動手段が、前記第2ロック部材をアンロック位置へ駆動する少なくとも1つの流体圧シリンダと、前記第2ロック部材をロック位置へ付勢する少なくとも1つの引っ張りスプリングとを有する。
(11)前記軸部材の回転位相がどのような回転位相であっても、前記進出位置にした複数のピン部材の先端側所定部分を複数の導入孔に導入可能に構成した。
第1ロック部材の複数の第1ロック部が、複数のピン部材のロック用係合部に周方向から係脱するため、信頼性の高いロック機能を得ることができる。このことは、第2ロック部材についても同様である。
スライドロック装置10は、フランジ部材20と、本体部材30と、補助本体部材50と、複数の保持孔31及び複数のピン部材32と、第1ロック手段60と、第2ロック手段80等を備えている。
4つのアクチュエータ40における4つの往動エア室41に共通の1つの第1エア供給/排出ポート43と、4つの復動エア室42に共通の1つの第2エア供給/排出ポート44とが環状部材33に設けられている。第1,第2エア供給/排出ポート43,44は、加圧エア供給源にエア通路(ホース又は配管)により夫々接続されている。
上記とは逆に、第2エア供給/排出ポート44に加圧エアを供給して4つの復動エア室42に加圧エアを夫々供給し、4つの往動エア室41から第1エア供給/排出ポート43へ加圧エアを排出すると、4つのピン部材32が進出位置から後退位置へ移動する。
第1ロック手段60は、プレス機械1 の稼働中に、4つのピン部材32を後退位置にロックするものである。ピン部材32の先端近傍部の外周近傍部には環状溝からなるロック用係合部32aが形成されている。第1ロック手段60は、図5,図6に示す環状の第1ロック部材61と、この第1ロック部材61をロック位置とアンロック位置とに亙って軸心Xの回りに回転駆動する第1駆動手段62を有する。第1ロック部材61(第1環状板部材に相当する)は、軸心Xと直交する平面と平行な板部材であり、環状部材33のフランジ部側端面又はその近傍位置に配置され、環状部材33とリング部材34の間に形成された環状溝に回動可能に装着されている。
4つのピン部材32を後退位置に保持して、第1ロック部材61を図5に示すロック位置にした状態では、4つの第1ロック部61aが対応するロック用係合部32aに夫々係合してピン部材32が軸心X方向へ移動不能になり、後退位置に保持される。
第2ロック手段80は、図8、図9に示す環状の第2ロック部材81と、この第2ロック部材81をロック位置とアンロック位置とに亙って軸心Xの回りに回転駆動する第2駆動手段82を有する。第2ロック部材81(第2環状板部材に相当する)は、軸心Xと直交する平面と平行な板部材であり、補助本体部材50のうちのフランジ部材20と反対側の端面又はその近傍位置に配置され、補助本体部材50と、この補助本体部材50の外端面に固定された蓋板88に固着されたリング部材88aとの間に回動可能に装着されている。
4つのピン部材32を進出位置に保持して、第2ロック部材81を図8に示すロック位置にした状態では、4つの第2ロック部81aが対応するロック用係合部32aに夫々係合してピン部材32が軸心X方向へ移動不能になり、進出位置に保持される。
第2エアシリンダ84は、単動型かつスプリング復帰型のシリンダであり、前記開口部50aの近傍において補助本体部材50に固定されたブラケット84aに固定され、そのロッドの先端の係合金具84bが腕部83に係合している。この第2エアシリンダ84は加圧エア供給源から延びるエア供給ホース(図示略)に接続されている。引っ張りスプリング85の一端は腕部83に固定されたピン85aに連結され、他端はブラケット84aに連結されている。
プレス機械1の稼働中においては、4つのピン部材32を後退位置に保持し、第1ロック部材61をロック位置に保持する。そのため、制御系の誤動作やアクチュエータ40の誤動作が発生しても、4つのピン部材32が後退位置を保持する。引っ張りスプリング65の付勢力で第1ロック部材61をロック位置に保持するため、第1エアシリンダ64へ加圧エアを供給不能になっても第1ロック部材61はロック位置を保持する。つまり、フェールセーフの信頼性に優れた機構になっている。
第1,第2ロック手段60,80は、軸心と直交する平面と平行な環状板部材である第1,第2ロック部材61,81を主体として構成するため、コンパクトな構成となり、スライドロック装置10の小型化を図ることができる。
第2ロック部材81の位置がロック位置かアンロック位置かを検知する第2検知手段90を設けたため、第1検知手段70によりアンロック位置を検知し且つ第2検知手段90によりロック位置を検知した場合に、全部のピン部材32が進出位置に位置し且つロック状態であると確認することができる。但し、第1エア供給/排出ポート43に加圧エアが供給されていることを条件とする。
1)保持孔31と支持孔51とピン部材32の数は4つに限定されるものではなく、3つ以下でもよく5つ以上でもよい。導入孔25の数は6つに限定されるものではなく、5つ以下でもよく7つ以上でもよい。導入孔25の数に応じて導入孔25の周方向のサイズも適宜設定可能である。
3)第1,第2駆動手段62,82を複動型流体圧シリンダで構成し、引っ張りスプリング65,85を省略することもできる。
