Description
ロボットの多関節アームの先端部に把持装置の本体が装着される。その本体内に設けられる駆動手段によって2つの可動部材が近づく方向および遠ざかる方向へ移動される。各可動部材に爪部材が着脱機構によって着脱可能に連結される。その着脱機構は、次のように構成される。可動部材の下面から連結ロッドが下方に突設される。その連結ロッドが、爪部材の上部に形成された装着孔に挿入可能となっている。その連結ロッドの上端部には永久磁石が装着される。その永久磁石に吸着される被吸着部が、爪部材の装着孔の周壁に設けられる。また、その連結ロッドの外周壁に支持孔が半径方に形成され、その支持孔に圧縮バネと係合ボールとが半径方向へ移動可能に装着される。その圧縮バネが係合ボールを半径方向の外方へ付勢する。その係合ボールが、爪部材の装着孔の内周壁に形成された凹部に挿入可能となっている。上記の連結ロッドが装着孔に挿入されたときに、連結ロッドの永久磁石が爪部材の被吸着部に吸着すると共に、係合ボールが装着孔の凹部に係合される。これにより、連結ロッドと爪部材とが連結される。
上記の爪部材が当該可動部材から取り外される方向へ、上記の永久磁石が被吸着部に吸着する力および圧縮バネの付勢力を越えて、何らかの外力が当該爪部材に作用することがある。この場合、爪部材が可動部材から少しでも離間されると、上記の吸着力が急激に低下して、爪部材が可動部材から意図せずに取り外される。
本発明の目的は、把持装置の爪部材を可動部材に強力に連結できる着脱機構を備える把持装置を提供することにある。
把持装置の本体1内に駆動手段2が設けられる。前記本体1の先端部に設けられる可動部材3,4が、駆動手段2によって水平方向へ移動可能となっている。前記可動部材3,4と前記爪部材22,62との間に着脱機構23,63が設けられる。その着脱機構23,63が、把持対象物Wに当接可能となっている爪部材22,62を前記可動部材3,4に着脱可能に連結させる。前記着脱機構23,63は、次のように構成される。前記可動部材3,4に案内孔24,64が前記水平方向に対して交差する方向に形成される。前記可動部材3,4から筒状の支持部材44,84が前記案内孔24,64内に突設される。前記支持部材44,84の筒壁に支持孔45,85が周方向へ所定の間隔をあけて半径方向へ貫通される。前記支持孔45,85に係合部材46,86が半径方向へ移動可能に挿入される。前記案内孔24,64に操作部材49,89が挿入される。その操作部材49,89が、前記可動部材3,4内に設けられる着脱用の駆動手段25,65によって軸方向へ移動可能となっている。前記係合部材46,86に係合されるように楔部50,90が前記操作部材49,89の内周壁に形成される。前記爪部材22,62に突設される連結ロッド53,93が、前記支持部材44,84の筒孔51,91に挿入可能となっている。前記連結ロッド53,93の外周壁に先端側に向うにつれて軸心に近づくように形成される係止部56,96が、前記係合部材46,86に当接可能となっている。
上記の把持装置では、爪部材が着脱機構を介して可動部材に連結された状態で、可動部材から離間される方向に何らかの外力が爪部材に作用したときに、着脱機構の構成部材同士の間に生じる摩擦力が、上記の外力に対する抵抗力として連結ロッドに作用する。これにより、その外力が連結ロッドと係止部と係合部材と楔部とを介して操作部材に受け止められる。その結果、連結ロッドが支持部材の筒孔から意図せずに取り外されることが防止される。
例えば、図1から図2Bに示すように、前記案内孔24,64に保持バネ41,81が設けられる。前記保持バネ41,81が前記操作部材49,89を介して前記係合部材46,86を半径方向の内方へ付勢する。
この場合、何らかの原因によって着脱用の駆動手段が作動できなくなったときでも、保持バネが操作部材の楔部と係合部材とを介して連結ロッドの係止部を押すので、爪部材が可動部材に連結された状態が維持される。
例えば、図3Aから図4Bに示すように、前記可動部材3,4および前記爪部材22,62のうちのいずれか一方に突出部58,98が設けられる。また、この突出部58,98が嵌まり込む凹部59,99が、前記可動部材3,4および前記爪部材22,62のうちの他方に設けられる。
この場合、把持用の駆動手段からの駆動力が、上記突出部および上記凹部を介して把持対象物に伝達されるので、連結ロッド等の着脱機構の構成部材が上記駆動力により摩耗したり破損したりすることを防止できる。
例えば、図3Aに示すように、前記突出部58が円柱状に形成される。
この場合、連結ロッド等の着脱機構の構成部材が摩耗したり破損したりすることを防止できる。
例えば、図4Aに示すように、前記突出部98が矩形状に形成される。
この場合、水平面内で回転させられる方向へ爪部材に作用する外力(偏心荷重)が、上記突出部および上記凹部を介して可動部材に受け止められるので、連結ロッド等の着脱機構の構成部材が上記外力により摩耗したり破損したりすることを防止できる。
例えば、図5Aおよび図5Bに示すように、前記可動部材3,4および前記爪部材22,62のうちのいずれか一方に、前記可動部材3,4の移動方向に延びるガイド凸部100が設けられる。また、このガイド凸部100が嵌まり込む溝101が、前記可動部材3,4および前記爪部材22,62のうちの他方に設けられる。
この場合、水平面内で回転させられる方向へ爪部材に作用する外力(偏心荷重)が、上記ガイド凸部および上記溝を介して可動部材に受け止められるので、連結ロッド等の着脱機構の構成部材が上記外力により摩耗したり破損したりすることを防止できる。
上記の把持装置の本体1内に上下方向に形成されるシリンダ孔5に、ピストン6が上下方向(軸方向)に移動可能で保密状に挿入される。そのピストン6から上方に突設された出力ロッド7が、本体1の上壁1aに保密状に挿入される。ピストン6の上側にクランプ室10が形成されると共に、ピストン6の下側にアンクランプ室11が形成される。そのクランプ室10に、圧縮エア(圧力流体)を供給および排出する給排路12が本体1に形成される。また、アンクランプ室11に、圧縮エアを供給および排出する別の給排路13が形成される。クランプ室10内に保持バネ14が装着され、その保持バネ14が本体1の上壁1aに対してピストン6を下方へ付勢する。
上記の第2着脱機構63においても、第2可動部材4内に上下方向に形成されるシリンダ孔64内に第2駆動手段65が設けられる。
上記の第1可動部材3の第1シリンダ孔24にピストン26が上下方向へ移動可能で保密状に挿入される。そのシリンダ孔24は、下側から順に形成される大径孔28と小径孔29とを有する。大径孔28にピストン26の大径部30が保密状に挿入され、小径孔29にピストン26の小径部31が保密状に挿入される。ピストン26の下側にロック室34が形成されると共に、大径孔28と小径部31との間にリリース室35が形成される。ロック室34に圧縮エアを供給および排出する給排路36が第1可動部材3に形成される。また、リリース室35に圧縮エアを供給および排出する別の給排路37が第1可動部材3に形成される。そのピストン26の下部に装着孔40が形成され、その装着孔40に保持バネ41が装着される。その保持バネ41が第1可動部材3の下壁3bに対してピストン26を上方に付勢する。
上記の第2着脱機構63の第2駆動手段65も上記の第1駆動手段25と同じような構成となっている。すなわち、第2可動部材4のシリンダ孔64にピストン66が上下方向へ移動可能で保密状に挿入される。シリンダ孔64の大径孔68にピストン66の大径部70が保密状に挿入され、シリンダ孔64の小径孔69にピストン66の小径部71が保密状に挿入される。圧縮エアが給排路76を通ってロック室74に供給および排出される。また、圧縮エアが別の給排路77を通ってリリース室75に供給および排出される。そのピストン66の装着孔80に保持バネ81が装着される。その保持バネ81が第2可動部材4の下壁4bに対してピストン66を上方に付勢する。
上記の第2着脱機構63においても、シリンダ孔64の天井壁64aから筒状の支持部材84が下方に突設され、その支持部材84の筒壁に支持孔85が半径方向に向けて形成されている。各支持孔85に係合ボール(係合部材)86が半径方向へ移動可能に挿入される。また、ピストン66の上部に筒状の操作部材89が設けられ、その操作部材89の内周壁に溝が上方へ向かうに半径方向の外方へ広がるように上下方向に形成される。その溝の周壁に形成される楔面(楔部)90に、係合ボール86が当接可能となっている。
上記の第2着脱機構63においては、上記のシリンダ孔64の上側に連通される挿入孔91が、第2可動部材4の上面4aに開口される。その挿入孔91の左方に長穴92が所定の間隔をあけて上下方向に形成される。また、上記の第2爪部材62の連結ロッド93が挿入孔91に挿入可能となっていると共に、ピン94が長穴92に挿入可能となっていることにより、第2可動部材4に対して爪部材62が回り止めされる。また、連結ロッド93の係止溝95の係止部96に、係合ボール86が係合可能となっている。なお、本実施形態においては、挿入孔91が支持部材84の筒孔によって構成されている。
上記の第2着脱機構63においても、上記のシリンダ孔64と長穴92との間に接触式センサ97が配置される。
図2Aに示す第1着脱機構23の初期状態(リリース状態)では、ロック室34から圧縮エアが排出されると共に、リリース室35に圧縮エアが供給されている。このため、リリース室35の圧縮エアに相当する下方への押圧力が保持バネ41の付勢力に抗してピストン26を下方へ移動させるように作用される。従って、係合ボール46が支持孔45内で半径方向の外方へ移動することが許容される。
上記の把持装置を図1に示すアンクランプ状態では、本体1内のクランプ室10から圧縮エア(圧縮流体)が排出されると共に、アンクランプ室11に圧縮エアが供給されている。アンクランプ室11の圧縮エアがピストン6を保持バネ14に抗して上限位置に押動している。
前記の第1爪部材22が第1可動部材3に装着された状態(連結状態)では、第1着脱機構23のピストン26が楔面50と係合ボール46と係止部56とを介して連結ロッド53を挿入孔51内に引き込むことにより、第1爪部材22が第1可動部材3の上面3aに強力に受け止められている。上記の連結状態において、その第1爪部材22の連結ロッド53に、何らかの上方への外力が作用することがある。このとき、楔面50と係合ボール46との間、および、係合ボール46と係止部56との間に摩擦力が生じており、その摩擦力が上記の上方へ外力の抵抗力として第1爪部材22に作用する。これにより、前記の上方への外力が楔面50と係合ボール46と係止部56とを介してピストン26に受け止められる。その結果、第1爪部材22が可動部材3から意図せずに取り外されるのを防止できる。
また、前記の第2爪部材62が第2可動部材4に装着された状態(連結状態)では、第2着脱機構63のピストン66が楔面90と係合ボール86と係止部96とを介して連結ロッド93を挿入孔91内に引き込むことにより、第2爪部材62が第1可動部材4の上面4aに強力に受け止められている。上記の連結状態において、その第2爪部材62の連結ロッド93に、何らかの上方への外力が作用することがある。このとき、楔面40と係合ボール86との間、および、係合ボール86と係止部96との間に摩擦力が生じており、その摩擦力が上記の上方への外力の抵抗力として第2爪部材62に作用する。これにより、前記の上方への外力が楔面90と係合ボール86とを介して係止部96に受け止められる。その結果、第2爪部材62が可動部材4から意図せずに取り外されるのを防止できる。
図3A、および図3Bの変形例が上記の実施形態と異なる点は次の通りである。
第1爪部材22がワークWに向けて押圧されるとき、駆動手段2からの駆動力(押圧力)が、嵌合している上記突出部58および上記凹部59を介してワークWに伝達されるので、連結ロッド53等の第1着脱機構23の構成部材が上記駆動力により摩耗したり破損したりすることを防止できる。
図4A、および図4Bの変形例が、図3A、および図3Bの変形例と異なる点は次の通りである。
水平面内で回転させられる方向へ第1爪部材22に作用する外力(偏心荷重)が、上記突出部98および上記凹部99を介して第1可動部材3に受け止められるので、連結ロッド53等の第1着脱機構23の構成部材が上記外力により摩耗したり破損したりすることを防止できる。
また、第1可動部材3に対する第1爪部材22の回り止めの機能も上記突出部98および上記凹部99は有する。
図5A、および図5Bの変形例が上記の実施形態と異なる点は次の通りである。
水平面内で回転させられる方向へ第1爪部材22に作用する外力(偏心荷重)が、上記溝101および上記ガイド凸部100を介して第1可動部材3に受け止められるので、連結ロッド53等の第1着脱機構23の構成部材が上記外力により摩耗したり破損したりすることを防止できる。
また、第1可動部材3に対する第1爪部材22の回り止めの機能も上記溝101および上記ガイド凸部100は有する。
上記の実施形態において、把持装置の上方から爪部材22,62を、何らかの搬送装置又は手動によって把持装置の本体1に搬入することに代えて、テーブル等の上に載置された爪部材22,62の上方から把持装置を何らかの搬送装置(ロボット)又は手動によって搬入させるようにしてよい。
