Description

【0001】
【発明の属する分野】
本発明は、ドラム缶等の大型容器をクランプして持ち上げ、所定位置に移動させて容器を反転させて内容物を放出する容器運搬車に関するものである。
【0002】
【従来の技術及び発明が解決しようとする課題】
斯種容器運搬車は、台車に昇降及び台車の接地面に対して垂直面内で傾動可能に傾動ポストを具え、該傾動ポストの上端に容器の上部を支持する上支持手段、下端に容器の下部を支持する下支持手段を具えている。
上支持手段と下支持手段とによって容器を保持することにより、容器を上昇位置で反転させることができる。
しかし、従来の下支持手段は、容器の胴部を半周する湾曲杆を、容器の浮上位置で前方へ反転させて容器胴部の前半周を包囲するものや、容器の下縁に引っかける爪片を容器の浮上位置で回動させて容器に引っ掛けるものであって、何れも手動操作せねばならず、面倒であった。
本発明は、上支持手段で容器上部を支持した状態で容器を持ち上げると自動的に下支持手段が容器下縁を確実に引っ掛けて支持できる容器運搬車を明らかにするものである。
【0003】
【課題を解決する手段】
本発明は、台車(1)上に昇降及び台車の接地面に対して垂直面内で傾動可能に傾動ポスト(3)を具え、該傾動ポスト(3)の上端に容器(200)の上部を支持する上支持手段(4)、下端側に容器(200)の下部を支持する下支持手段(5)を具えた容器運搬車において、下支持部材(5)は、傾動ポスト(3)内にスライド可能に配備された杆部材(6)と、杆部材(6)のスライド範囲を規制するスライド範囲規制手段(7)と、杆部材(6)に直接或いは回動アーム(66)を介して間接的に設けられ台車(1)上の受け部(10)に当たって杆部材(6)の下降位置を規制する当り部(62)と、杆部材(6)の下部に配備され容器下縁(202)に内側から引っ掛かり可能な掛かり片(52)を含み傾動ポスト(3)に対して相対的に杆部材(6)が下向き移動することによって掛かり片(52)を待機位置から容器(200)の底側へ回転させるリンク機構(51)とによって構成される。
【0004】
【作用及び効果】
上支持手段(4)によって容器(200)を支持した状態で傾動ポスト(3)を上昇させて容器(200)を持ち上げる。傾動ポスト(3)の上昇に追従して傾動ポスト(3)に対して相対的に杆部材(6)が下向き移動し、これによってリンク機構(51)の働きにより掛かり片(52)が容器の底側へ回転して容器下縁(202)に引っ掛かる。
上記の如く、掛かり片(52)の容器下縁(202)への引っ掛かり動作は、容器(200)の持ち上げ動作に連動して自動的に行われるため、手間が掛からず、又、掛かり片(52)の掛け忘れのために、上昇位置でドラム缶を反転させて大きな事故を招来することはない。
【0005】
容器を縦向きのまま降ろすと、容器が接地する前に杆部材(6)上の当り部(62)が台車(1)上の受け部(10)に当たって、その後は傾動ポスト(3)の下降に応じて杆部材(6)が相対的に傾動ポスト(3)に押し込まれ、リンク機構(51)の働きにより掛かり片(52)が容器下縁(202)から離れた待機位置に復帰し、容器は支障なく接地できる。
【0006】
【発明の実施の形態】
第1実施例
図1乃至図10は容器下縁(202)に引っ掛かる掛かり片(52)を油圧シリンダ装置にて容器下縁(202)に引っ掛ける方式の運搬車である。
以下の説明で、前とは運搬車の前進方向で図1、図2では左側であり、後とは運搬車の後退方向である。
図1、図2示す如く、台車(1)はベース板(11)に開口を前方に向けたU型フレーム(12)の中央部を接続し、ベース板(11)に縦長の昇降用ガイド枠(13)、昇降用シリンダ装置(23)及び足踏み式油圧ポンプ(92)を有している。
台車(1)にはベース板(11)とU型フレーム(12)の両端に車輪(14)(14)、(15)(15)が設けられている。
【0007】
昇降用ガイド枠(13)に昇降台(2)が配備される。昇降台(2)は昇降用ガイド枠(13)に昇降可能に取り付けられた昇降ベース(22)に、開口を前方に向けたU型フレーム(21)の中央部を接続して構成される。昇降台(2)のU型フレーム(21)と前記台車(1)のU型フレーム(12)は台車(1)の接地面に対して平行姿勢である。
昇降ベース(22)にチェン(24)の一端が係止され、該チェン(24)は昇降用シリンダ装置(23)のピストンロッド先端に回転自由に設けられた歯車(23a)を経由してベース板(11)に係止される。
前記油圧ポンプ(92)の足踏み操作によりピストンロッドが上方に突き出して昇降台(2)が上昇する。
【0008】
昇降台(2)のU型フレーム(21)内に半円状の反転枠(25)が配備され該反転枠(25)の両端がU型フレーム(21)の両端に軸承される。
昇降台(2)のU型フレーム(21)の一端には手動式反転駆動装置(26)が搭載され反転枠(25)に連繋される。手動式反転駆動装置(26)のハンドル(27)を手回しすることにより、反転枠(25)を台車(1)の接地面に対して垂直な面内で回動させることができる。
【0009】
反転枠(25)の中央に該反転枠(25)に直交して角筒状傾動ポスト(3)が突設されている。反転枠(25)は傾動ポスト(3)の長さ方向の中央部両側から1/2ずつが左右に突出した状態に傾動ポスト(3)と一体化している。
傾動ポスト(3)の上端に容器(200)の上部を支持する上支持手段(4)が、傾動ポスト(3)の下側に容器(200)の下部を支持する下支持手段(5)が配備される。
【0010】
上支持手段(4)は傾動ポスト(3)の上端から前方に向けて突設した下爪(41)と、該下爪(41)の上方にて上下方向に回転して開閉する上爪(42)とによって構成され、該上爪(42)は後記する押圧用油圧シリンダ装置(81)に連繋される。
【0011】
傾動ポスト(3)内の下部に角筒状の杆部材(6)が該ポストの下端に臨出してスライド可能に配備される。
杆部材(6)は、該杆部材(6)の上部に配備した4つの回転丸板(65)と傾動ポスト(3)の下部に設けたガイドローラ(32)(33)に案内されて傾動ポスト(3)内をスライドする。
杆部材(6)の上端に前後方向に向けて平行に突設された板片(63)(63)を貫通した2本の軸(64)(64)の両端に上記回転丸板(65)が取り付けられている。
ガイドローラ(32)(33)は、傾動ポスト(3)の下端両側面に下向きに突設した支持片(31)(31)間に、杆部材(6)を挟む様に取り付けられている。
支持片(31)(31)の前端に跨って胴当り板(57)が固定されている。
胴当り板(57)は容器(200)の胴部に沿う様に湾曲しており、後記の如く上支持手段(4)にて容器(200)の上縁(201)をクランプして持ち上げたとき、容器(200)胴部に当たって容器の縦向き姿勢を保つ。
【0012】
図6に示す如く、杆部材(6)の板片(63)に押圧用油圧シリンダ装置(81)のピストンロッド(85)が枢支連結され、該押圧用油圧シリンダ装置(81)のシリンダ(84)の基端は前記油圧ポンプ(92)に繋がる流路を有するヘッド(82)に一体に接続される。該ヘッド(82)と前記上爪(42)が枢支連結される。
押圧用油圧シリンダ装置(81)は杆部材(6)を傾動ポスト(3)から下向きに突き出すための押圧手段(8)である。
又、上記押圧用油圧シリンダ装置(81)のシリンダ(84)は、バネ(86)によって下向き、即ち、上爪(42)を下爪(41)に対して開く方向に付勢されてる。
【0013】
図5に示す如く杆部材(6)の下端に、後方へL型に屈曲した2つの平行屈曲片(61)(61)が突設され、両屈曲片(61)の屈曲部間にて掛かり片(52)の基端がピン(54)によって、前記反転枠(25)の反転面内と同一面内で回動可能に取り付けられている。
前記支持片(31)(31)の下端と掛かり片(52)が、左右一対の連結リンク(53)(53)とピン(55)(56)によって枢支連結され、連結リンク(53)と掛かり片(52)とによってリンク機構(51)が構成させる。
リンク機構(51)は、前記押圧用油圧シリンダ装置(81)によって傾動ポスト(3)の下端から杆部材(6)が突き出る動きを、掛かり片(52)が下方から前方へ回転する動きに変換する。
【0014】
前記傾動ポスト(3)には、杆部材(6)のスライド範囲を規制するスライド範囲規制手段(7)が設けられ、実施例のスライド範囲規制手段(7)は、傾動ポスト(3)の長さ方向の略中央部に設けた上ストッパ軸(71)と下端寄りに設けた下ストッパ軸(72)であって、両ストッパ軸(71)(72)は傾動ポスト(3)の両側壁を貫通して取り付けられ、杆部材(6)の板片(63)の移行路に位置している。
上ストッパ軸(71)は、前記シリンダ付勢バネ(86)の止め軸を兼用している。
【0015】
前記杆部材(6)下端の両屈曲片(61)(61)の先端に該屈曲片(61)の屈曲方向に直交して外向きに当り部(62)(62)が突設されている。
に示す如く、前記台車(1)には上記当り部(62)(62)の下降路に向けて2つの受け部(10)(10)が前方に向けて突設されている。図6に示す如く、当り部(62)(62)が受け部(10)(10)に乗り、杆部材(6)上端の板片(63)が杆部材(6)のストッパ軸(71)(72)に当たった状態で、昇降台(2)の下降位置が決まる。
上記昇降台(2)下降位置において、上支持手段(4)の下爪(41)の高さ位置は床面上の容器(200)の上縁(201)よりも少し低い位置にある。
【0016】
図3は、前記昇降用シリンダ装置(23)及び押圧用油圧シリンダ装置(81)の駆動油圧回路(9)を示している。
作業油タンク(90)と昇降用シリンダ装置(23)を繋ぐメイン流路(91)に油圧ポンプ(92)が接続され、メイン流路(91)の油圧ポンプ(92)より上流側と下流側に夫々昇降用シリンダ装置(23)側への流れを許す逆止弁(98)(98)が設けられる。
メイン流路(91)には分岐流路(93)が設けられて押圧用油圧シリンダ装置(81)が接続される。メイン流路(91)には分岐流路(93)よりも上流側にタンクへ戻る戻り流路(94)が接続され、該戻り流路(94)に下降用リリース弁(95)が設けられる。
メイン流路(91)の2つの逆止弁(98)(98)間と戻り流路(94)の下降用リリース弁(95)の下流側とがバイパス流路(99)にて繋がれ、該バイパス流路(99)にリリーフ弁(96)が設けられる。
図1に示す如く、油圧ポンプ(92)の近傍に設けられ、ノブ(95a)を回して操作する。
【0017】
前記押圧用油圧シリンダ装置(81)への分岐流路(93)にチェックバルブ(97)が設けられる。
図1に示す如く、チェックバルブ(97)は前記昇降台(2)の昇降ベース(22)上に取り付けられ、昇降台(2)が下降位置にある時は、チェックバルブ(97)に突設したカムフォロアー(97a)が台車(1)上のカム板(36)に当たって、押圧用油圧シリンダ装置(81)からメイン流路(91)への作業油の流出を許す。昇降台(2)が上昇してチェックバルブ(97)がカム板(36)より高位置に達すると押圧用油圧シリンダ装置(81)からの作業油の流出は阻止される。
後記の如く、押圧用油圧シリンダ装置(81)によって上支持手段(4)の上爪(42)が閉じられている状態で、押圧用油圧シリンダ装置(81)からの作業油の流出が阻止されると、上爪(42)は閉じ状態にロックされる。
即ち、チェックバルブ(97)とカム板(36)は、上爪(42)のロック手段を構成する。
【0018】
然して、図1に示す如く、床面に起立状態の容器(200)に対して、台車(1)を突っ込んで、昇降台(2)の反転枠(25)内に容器胴部を侵入させる共に、上支持手段(4)の下爪(41)を胴部上部に当てる。
油圧ポンプ(92)を足踏み操作する。
メイン流路(91)に流れた作業油は負荷の小さい押圧用油圧シリンダ装置(81)を作動して上爪(42)を閉じ、下爪(41)と上爪(42)とによって容器上縁をクランプする。
【0019】
押圧用油圧シリンダ装置(81)は杆部材(6)を下向きに突き出そうとするが、図5、図6に示す如く、杆部材(6)上の当り部(62)が台車(1)上の受け部(10)に乗っているから、杆部材(6)の突き出しは阻止される。このため、作業油は昇降用シリンダ装置(23)に流入して負荷の大きいピストンロッドを突き出して昇降台(2)を上昇させる。
油圧ポンプ(92)の足踏み操作を続けて昇降台(2)を上昇させると、受け部(10)に対して杆部材(6)上の当り部(62)が浮上するため、作業油は押圧用油圧シリンダ装置(81)に流入して傾動ポスト(3)に対して相対的に杆部材(6)を突き出す。
この動作は昇降台(2)の上昇に追従するため、受け部(10)に当り部(62)が乗ったまま、傾動ポスト(3)だけが上昇するかの様に見える。
【0020】
傾動ポスト(3)に対して相対的に杆部材(6)が突き出すと、図8に示す如く、リンク機構(51)の働きによって掛かり片(52)が前方へ回転して先端の爪片(52a)が容器底部が下縁(202)に引っ掛かる。又、杆部材(6)上の板片(63)が下当り軸(72)に当たって、杆部材(6)のそれ以上の突き出しは阻止される。
容器(200)の上縁(201)と下縁(202)は上支持手段(4)と下支持手段(5)によって確実に支持されたことになる。
図9は、図8よりも少し高さの大きい容器を支持した状態を示しており、杆部材(6)が下当り軸(72)に当たる手前で掛かり片(52)は容器(200a)の下縁に引っ掛かる。
【0021】
以後の油圧ポンプ(92)からの作業油は、昇降用シリンダ装置(23)のみに流入し、昇降台(2)を上昇させる。昇降台(2)の更なる上昇により、昇降台(2)上のチェックバルブ(97)が台車(1)上のカム板(36)を越えた時点で、押圧用油圧シリンダ装置(81)から作業油の流出が阻止されて、上爪(42)は閉じ状態にロックされる。又、掛かり片(52)も容器下縁(202)に引っ掛かった状態にロックされる。
従って、反転枠(25)即ち容器(200)がどの様な姿勢でも、傾動ポスト(3)に沿わせて容器を確実に保持できる。
【0022】
チェックバルブ(97)を省略した場合、図10に示す如く、昇降台(2)の上昇位置で手動式反転駆動装置(26)によって反転枠(25)を反転させ、容器(200)の内容物を投入口(300)に放出すべく下降用リリースバルブ(95)を開いて容器の排出口を投入口(300)の高さに対応させる際に、容器が投入口(300)に乗ってしまった場合、押圧用油圧シリンダ装置(81)内の作業油は開放さている降用リリースバルブ(95)を通じてタンク(90)に逃げてしまい、上爪(42)が開いて容器上縁(201)のクランプを開放してしまい、容器が落下する危険がある。上記実施例1では、上爪(42)はロックされて開くことなく、この様な危険を排除できる。
【0023】
容器(200)を床面に降ろすには、手動式反転駆動装置(26)によって反転枠(25)を元の水平姿勢に戻して容器(200)を起立させ、下降用リリースバルブ(95)を開く。
昇降用シリンダ装置(23)内の作業油がタンク(90)へ排出されて昇降台(2)が下降する。下降途上でチェックバルブ(97)がカム板(36)によって動作し、押圧用油圧シリンダ装置(81)に通じる分岐流路(93)を開放するが、昇降台(2)及び容器(200)の重量が作用している昇降用シリンダ装置(23)からの作業油の排出が優先する。
【0024】
昇降台(2)が下降端に達する少し手前で、杆部材(6)の上の当り部(62)が台車(1)の受け部(10)に当たって杆部材(6)の下降は阻止され、反転枠(25)を含む傾動ポスト(3)だけが更に下降する。これによってリンク機構(51)の働きにより、掛かり片(52)が前記とは逆方向に回動して元の待機位置に復帰する。
昇降台(2)が下降端に達すると容器(200)は床面に接地し、押圧用油圧シリンダ装置(81)のピストンロッド(85)がバネ(86)力で引っ込んで作業油をタンク(90)に排出する。これによって上爪(42)が開いて容器上縁(201)のクランプを開放出来る。
【0025】
上記の如く、上爪(42)の閉じ動作による該上爪(42)と下爪(41)とによる容器上縁(201)のクランプ動作、容器(200)の持ち上げ動作及び掛かり片(52)の容器下縁(202)への引っ掛かりによる容器下縁(202)の支持動作は、油圧ポンプ(92)の足踏み操作によって自動的に行われるため、手間が掛からず、又、掛かり片(52)の掛け忘れのために、上昇位置でドラム缶を反転させて大きな事故を招来することはない。
【0026】
又、上爪(42)と掛かり片(52)駆動用の押圧用油圧シリンダ装置(81)に対して、容器の持ち上げ位置で利くチェックバルブ(97)を連繋したため、押圧用油圧シリンダ装置(81)からの不用意な作業油の排出を防止して、容器の落下等の危険を排除できる。
【0027】
第2実施例
図11乃至図16は第2実施例の傾動ポスト(3)、該ポストの上端の上支持手段(4)と下端側の下支持手段(5)を示している。
第2実施例は、上支持手段(4)は手動操作で行い、下支持手段(5)は杆部材(6)の自重で掛かり片(52)を動作させる点が前記第1実施例と異なる。
第1実施例の台車(1)、昇降台(2)は第2実施例と共通であるので、台車と昇降台の説明は省略する。
昇降台(2)の昇降は、台車(1)の油圧ポンプ(92)の足踏み操作と、下降用リリースバルブ(95)の操作によって行う。
【0028】
図11に示す如く、上支持手段(4)は、角筒状傾動ポスト(3)上端から前方に突設した下爪(41)と、該下爪(41)に対して上方から回転して閉じる上爪(42)とから成り、傾動ポスト(3)上の軸(44)に回転可能に取り付けたクランプネジ(43)を上爪(42)の後側自由端に設けた回転軸(42a)を直交して貫通螺合させた公知の構成である。クランプネジ(43)上端のノブ(43a)を回すと、ネジ推力により上爪(42)が下爪(41)に対して閉じ、ノブ(43a)の逆方向に回すと上爪(42)が開く。
【0029】
傾動ポスト(3)内の下部に角筒状の杆部材(6)が該ポストの下端に臨出してスライド可能に配備される。
杆部材(6)は、第1実施例と同様にして、該杆部材(6)の上部に配備した4つの回転丸板(65)と傾動ポスト(3)の下部に設けたガイドローラ(32)(33)に案内されて傾動ポスト(3)内をスライドする。
回転丸板(65)は、杆部材(6)の上端に前後方向に向けて平行に突設した板片(63)(63)を貫通した2本の軸(64)(64)の両端に取り付けられている。
ガイドローラ(32)(33)は、傾動ポスト(3)の下端両側面に下向きに突設した支持片(31)(31)間に、杆部材(6)を挟む様に取り付けられている。
支持片(31)(31)の前部に、容器(200)の胴部に当たる円弧状の胴当り板(57)が支持片(31)(31)に跨って固定されている。
【0030】
図13に示す如く、杆部材(6)の板片(63)(63)間に板状のロック部材(101)の一端がピン(102)によって傾動ポスト(3)の軸心を含む面内で回転可能に支持されている。
ロック部材(101)の中央に貫通孔(101a)、自由端に切欠(101b)が開設されている。
ロック部材(101)の下面に、貫通孔(101a)の孔縁に面して該ロック部材の自由端側に半割ナット(104)を溶接等で固定している。
【0031】
傾動ポスト(3)内に、ロック部材(101)及びロック部材(101)を介して杆部材(6)を傾動ポスト(3)の下端から押し出す方向に付勢するバネ(87)が配備される。
バネ(87)は全長に亘ってネジ軸である支持軸(103)に嵌まり、該支持軸(103)は上端が上支持手段(4)近傍の軸(103a)に枢支され、自由端を前記ロック部材(101)の貫通孔(101a)を少し余裕のある状態に貫通して杆部材(6)内に侵入させている。
支持軸(103)上のバネ(87)は、ロック部材(101)に当たって該ロック部材(101)の自由を掛かり片(52)側に押圧しており、ロック部材(101)が支持軸(103)に対して傾くと、ロック部材(101)の孔縁とネジ軸である支持軸(103)が噛み合い、更に半割ナット(104)が支持軸のネジ面に噛み合う。この状態では、ロック部材(101)は杆部材(6)を傾動ポスト(3)に押し込む方向に対して阻止する様にロックする。 しかし、杆部材(6)を傾動ポスト(3)から引き出す力に対しては、ロック部材(101)の自由端はピン(102)を中心に上支持手段(4)側への回転が許されるため、支持軸(103)上をロック部材(101)を引きずる様にして杆部材(6)は傾動ポスト(3)に対して飛び出し側に移動可能であり、ロックは効かない。
【0032】
傾動ポスト(3)には、第1実施例と同様にして、上下2本のストッパ軸(71)(72)による杆部材(6)のスライド範囲規制手段(7)が設けられている。
【0033】
図11、図15に示す如く、杆部材(6)の下端に、後方へL型に屈曲した2つの平行屈曲片(61)(61)が突設され、両屈曲片(61)(61)の外側にピン(54)によってアーム(66)(66)が自由端を後方に向けて回動可能に配備される。
アーム(66)(66)の自由端間の下面間を連結杆(68)で連結し、両アームの自由端にアームと直交して外向きに当り部(62)を突設している。
アーム(66)(66)を連結する連結杆(68)は、アーム(66)の上向き回転時に、杆部材(6)の屈曲片(61)に当たって、杆部材(6)に対するアーム(66)の上向き回転を規制するストッパ(69)を兼用している。
【0034】
図11に示す如く、当り部(62)(62)が前記第1実施例と同様にして、台車(1)上の受け部(10)(10)に乗り、連結杆(68)に杆部材(6)の屈曲片(61)(61)が乗り、杆部材(6)上の板片(63)がスライド範囲規制手段(7)の上当り軸(71)に当たった状態で、傾動ポスト(3)、即ち、昇降台(2)の下降位置が決まる。
上記昇降台(2)の下降位置において、上支持手段(4)の下爪(41)の高さ位置は床面上の容器(200)の上縁(201)よりも少し低い位置にある。
【0035】
図11、図14に示す如く、上記アーム(66)(66)の上部間に連結軸(67)を回転可能に掛け渡し、該連結軸(67)に直交してロック解除ロッド(105)の基端を連結する。
ロック解除ロッド(105)の自由端は杆部材(6)に沿って傾動ポスト(3)内に侵入させて、図13に示す如く、ロック部材(101)の切欠(101b)に嵌めている。ロック部材(101)の先端部はネジ軸であって、ロック部材(101)が少し上下に揺動できる余裕のある状態にロック部材(101)を挟んで上下にダブルナット(106)(106a)を施して、ロック部材(101)のピン(102)を中心とする揺動範囲を規制する規制手段を構成している。
【0036】
前記杆部材(6)上の当り部(62)が台車(1)上の受け部(10)に乗って、昇降台(2)が下降位置にある状態で、ロック解除ロッド(105)の下ダブルナット(106a)がロック部材(101)を押し上げて、該ロック部材(101)を支持軸(103)に対して直交する面内に保持し、ロック部材(101)と支持軸(103)のロックを解除する。
台車(1)が上昇すると、アーム(66)は自重によって自由端が下がり、ロック解除ロッド(105)がロック部材(101)の自由端を下向きに引っ張ってロック部材(101)を傾動ポスト(3)に押し込む方向の移動を阻止する様に支持軸(103)をロックする。但し、前記の如く、杆部材(6)を傾動ポスト(3)から引き出す方向の力に対してはロックは効いていない。
【0037】
尚、実施例ではロック解除ロッド(105)によって、ロック部材(101)を下向きに引っ張り、矯正的にロックを効かしているが、ロック解除ロッド(105)によって引っ張らなくても、ロック部材(101)は自由端が自重で下がり、支持軸(103)に噛み込ませることは可能である。
【0038】
前記の如く、アーム(66)(66)を連結する連結杆(68)によって、杆部材(6)に対するアーム(66)の上向き回転は規制されるから、ロック解除ロッド(105)を介してロック部材(101)の自由端が支持軸(103)に対して直交する面内より上向きに回転して支持軸(103)がロック部材(101)の孔縁に噛み合うこと、即ち、傾動ポスト(3)に対して相対的に杆部材(6)が上向に移動することを阻止されることはない。
【0039】
前記杆部材(6)の両屈曲片(61)(61)の屈曲部間にて掛かり片(52)の基端が前記アーム(66)(66)を枢支するピン(54)上に、前記反転枠(25)の反転面内と同一面内で回動可能に取り付けられている。
前記支持片(31)(31)の下端と掛かり片(52)が左右一対の連結リンク(53)(53)とピン(55)(56)に枢支連結され、連結リンク(53)と掛かり片(52)とによってリンク機構(51)が構成される。
リンク機構(51)は、傾動ポスト(3)の下端から相対的に杆部材(6)が突出する動きを、掛かり片(52)が下方から前方へ回転する動きに変換する。
【0040】
然して、第1実施例と同様にして、図1に示す如く、床面に起立状態の容器(200)に対して、台車(1)を突っ込んで、昇降台(2)の反転枠(25)内に容器胴部を侵入させる共に、上支持手段(4)の下爪(41)を胴部上部に当てる。
図11に示すクランプネジ(43)を回して上爪(42)を閉じ、下爪(41)と上爪(42)とによって容器上縁上縁(201)をクランプする。
【0041】
油圧ポンプ(92)を足踏み操作すると、昇降用シリンダ装置(23)によって昇降台(2)が容器(200)上縁をクランプしたまま上昇する。この昇降台(2)の上昇により前記の如く、アーム(66)(66)の自由端が下がり、杆部材(6)は自重とバネ(87)の押圧によって傾動ポスト(3)に対して相対的に下降し、リンク機構(51)の働きにより、図15に示す如く、掛かり片(52)が前方へ回転して先端の爪片(52a)が容器下縁(202)に引っ掛かる。又、杆部材(6)上の板片(63)が下当り軸(72)に当たって、杆部材(6)のそれ以上の突き出しは阻止される。
【0042】
容器(200)は、上縁(201)と下縁(202)が上支持手段(4)と下支持手段(5)によって支持されたことになる。
前記の如く、昇降台(2)の上昇により、杆部材(6)はロック部材(101)によって支持軸(103)に対して上支持手段(4)側への移動、即ち、傾動ポスト(3)に対して杆部材(6)を押し込む方向への移動を阻止する様にロックされるから、容器(200)の持ち上げ或いは反転中に掛かり片(52)が容器下縁(202)から外れることはない。
【0043】
図16は図15よりも少し高さの大きい容器を支持した状態を示しており、杆部材(6)が下当り軸(72)に当たる手前で掛かり片(52)は容器(200a)の下縁に引っ掛かる。
【0044】
容器(200)を床面に降ろすには、上昇位置の容器(200)を起立姿勢に戻し、下降用リリースバルブ(95)を開く。昇降用シリンダ装置(23)内の作業油はタンク(90)へ流出して、台車(1)が下降する。
【0045】
昇降台(2)が下降端に達する少し手前で、杆部材(6)の上の当り部(62)が台車(1)の受け部(10)に当たって杆部材(6)の下降は阻止されるが傾動ポスト(3)は下降する。
当り部(62)が受け部(10)(10)に当たると、アーム(66)(66)の自由端が杆部材(6)に対して相対的に少し持ち上がり、ロック解除ロッド(105)を少し突き上げて、支持軸(103)に対するロック部材(101)のロックを解除する。これによって杆部材(6)は傾動ポスト(3)に対して相対に押し込まれ、リンク機構(51)の働きにより、掛かり片(52)が前記とは逆方向に回動して元の待機位置に復帰する。
【0046】
上記の如く、容器(200)の持ち上げ動作及び掛かり片(52)の容器下縁(202)への引っ掛かりによる容器下縁(202)の支持動作は、油圧ポンプ(92)の足踏み操作によって自動的に行われるため、手間が掛からず、又、掛かり片(52)の掛け忘れのために、上昇位置でドラム缶を反転させて大きな事故を招来することはない。
【0047】
又、ロック部材(101)によるロック手段(100)により、容器の持ち上げ動作や反転動作中に、掛かり片(52)が容器下縁(202)から外れることがないため、容器落下の危険を排除できる。
【0048】
上記第2実施例において、ロック部材(101)を付勢するバネ(87)は杆部材(6)を傾動ポスト(3)から押し出す作用を有するが、ロック部材(101)をトーションバネ(図示せず)等により、支持軸(103)に対して噛み合う方向にのみ付勢して、杆部材(6)を傾動ポスト(3)から押し出す作用がない場合でも実施可能である。この場合、昇降台(2)の上昇時に、杆部材(6)は自重のみで傾動ポスト(3)から相対的に突き出して、掛かり片(52)を容器下縁(202)に引っ掛かる方向に回動させることができる。
【0049】
本発明の実施に際して上支持手段(4)は、容器の上部を確実に支持できるものであれば、構成を問わない等、本発明は上記実施例の構成に限定されることはなく、特許請求の範囲に記載の範囲で種々の変形が可能である。

Figure2As shown in FIG. 2, the carriage (1) has two receiving portions (10) and (10) projecting forward toward the descending path of the contact portions (62) and (62). As shown in FIG. 6, the contact portions (62) and (62) ride on the receiving portions (10) and (10), and the plate member (63) at the upper end of the flange member (6) is the stopper shaft (71) of the flange member (6). In the state of hitting (72), the lowering position of the lifting platform (2) is determined.
In the lowered position of the lifting platform (2), the height of the lower pawl (41) of the upper support means (4) is slightly lower than the upper edge (201) of the container (200) on the floor.
[0016]
FIG. 3 shows a drive hydraulic circuit (9) of the elevating cylinder device (23) and the pressing hydraulic cylinder device (81).
A hydraulic pump (92) is connected to the main flow path (91) connecting the working oil tank (90) and the lifting cylinder device (23), and the upstream side and the downstream side of the hydraulic pump (92) of the main flow path (91). Are provided with check valves (98) and (98) that allow flow to the cylinder device (23) for raising and lowering, respectively.
The main flow path (91) is provided with a branch flow path (93) to which a pressing hydraulic cylinder device (81) is connected. A return flow path (94) returning to the tank is connected to the main flow path (91) upstream of the branch flow path (93), and a release valve (95) for lowering is provided in the return flow path (94). .
The bypass channel (99) connects between the two check valves (98) (98) of the main channel (91) and the downstream side of the release valve (95) for lowering the return channel (94). A relief valve (96) is provided in the bypass flow path (99).
As shown in FIG. 1, it is provided in the vicinity of the hydraulic pump (92), and is operated by turning the knob (95a).
[0017]
A check valve (97) is provided in the branch passage (93) to the pressing hydraulic cylinder device (81).
As shown in FIG. 1, the check valve (97) is mounted on the lift base (22) of the lift base (2), and protrudes from the check valve (97) when the lift base (2) is in the lowered position. The cam follower (97a) hits the cam plate (36) on the carriage (1) to allow the working oil to flow from the pressing hydraulic cylinder device (81) to the main flow path (91). When the lifting platform (2) rises and the check valve (97) reaches a higher position than the cam plate (36), the working oil is prevented from flowing out of the pressing hydraulic cylinder device (81).
As described later, in the state where the upper claw (42) of the upper support means (4) is closed by the pressing hydraulic cylinder device (81), the working oil is prevented from flowing out from the pressing hydraulic cylinder device (81). Then, the upper claw (42) is locked in the closed state.
That is, the check valve (97) and the cam plate (36) constitute locking means for the upper pawl (42).
[0018]
However, as shown in FIG. 1, the carriage (1) is pushed into the container (200) standing upright on the floor surface, and the container body is intruded into the reversal frame (25) of the lifting platform (2). The lower nail (41) of the upper support means (4) is applied to the upper part of the trunk.
Step on the hydraulic pump (92).
The working oil that has flowed into the main channel (91) operates the hydraulic cylinder device for pressing (81) with a small load to close the upper claw (42), and the upper claw (41) and the upper claw (42) Clamp the edges.
[0019]
The pressing hydraulic cylinder device (81) tries to project the saddle member (6) downward, but as shown in FIGS. 5 and 6, the contact portion (62) on the saddle member (6) is located on the carriage (1). Since it is on the receiving part (10), the protrusion of the flange member (6) is prevented. For this reason, the working oil flows into the elevating cylinder device (23) and the piston lock is heavily loaded.DoProtruding and raising the lifting platform (2).
When the foot of the hydraulic pump (92) is continuously stepped on and the lift (2) is raised, the contact part (62) on the saddle member (6) rises against the receiving part (10), so the working oil is pressed. It flows into the hydraulic cylinder device (81) and projects the flange member (6) relative to the tilting post (3).
Since this operation follows the rise of the lifting platform (2), it appears as if only the tilting post (3) is raised while the contact portion (62) is on the receiving portion (10).
[0020]
When the flange member (6) protrudes relative to the tilting post (3), as shown in FIG. 8, the hook piece (52) is rotated forward by the action of the link mechanism (51), and the claw piece at the tip ( 52a) the bottom of the container is caught on the lower edge (202). Further, the plate piece (63) on the flange member (6) hits the lower abutting shaft (72), and further protrusion of the flange member (6) is prevented.
The upper edge (201) and the lower edge (202) of the container (200) are securely supported by the upper support means (4) and the lower support means (5).
FIG. 9 shows a state in which a container having a slightly higher height than that in FIG. 8 is supported, and the hook piece (52) is under the container (200a) just before the eaves member (6) hits the lower contact shaft (72). Get caught on the edge.
[0021]
Subsequent working oil from the hydraulic pump (92) flows only into the lifting cylinder device (23) and raises the lifting platform (2). When the check valve (97) on the lifting platform (2) exceeds the cam plate (36) on the carriage (1) due to the further raising of the lifting platform (2), the pressing hydraulic cylinder device (81) The outflow of the working oil is prevented, and the upper claw (42) is locked in the closed state. The hook piece (52) is also locked in a state of being hooked on the lower edge (202) of the container.
Therefore, even if the reversal frame (25), that is, the container (200) is in any posture, the container can be reliably held along the tilting post (3).
[0022]
When the check valve (97) is omitted, as shown in FIG. 10, the reversing frame (25) is reversed by the manual reversing drive device (26) at the raised position of the lifting platform (2), and the contents of the container (200) When the release valve (95) for lowering is opened to release the gas to the inlet (300) and the outlet of the container is made to correspond to the height of the inlet (300), the container gets on the inlet (300). In this case, the working oil in the pressing hydraulic cylinder device (81) escapes to the tank (90) through the open release valve (95), and the upper claw (42) opens to open the upper edge (201) of the container. There is a risk that the container will fall due to opening the clamp. In the first embodiment, such a danger can be eliminated without the upper claw (42) being locked and opened.
[0023]
In order to lower the container (200) to the floor surface, the reversing frame (25) is returned to the original horizontal posture by the manual reversing drive device (26), the container (200) is erected, and the release valve (95) for lowering is lowered. open.
The working oil in the lifting cylinder device (23) is discharged to the tank (90), and the lifting platform (2) is lowered. During the downward movement, the check valve (97) is operated by the cam plate (36) to open the branch passage (93) leading to the pressing hydraulic cylinder device (81), but the lift (2) and the container (200) Priority is given to the discharge of the working oil from the lifting cylinder device (23) on which the weight acts.
[0024]
Slightly before the lifting platform (2) reaches the descending end, the contact portion (62) on the saddle member (6) hits the receiving portion (10) of the carriage (1) to prevent the descending of the saddle member (6), Only the tilting post (3) including the reversal frame (25) is further lowered. As a result, by the action of the link mechanism (51), the hook piece (52) rotates in the opposite direction to the above and returns to the original standby position.
When the lifting platform (2) reaches the descending end, the container (200) is grounded to the floor surface, and the piston rod (85) of the pressing hydraulic cylinder device (81) is retracted by the spring (86) force, and the working oil is stored in the tank ( 90). As a result, the upper claw (42) is opened, and the clamp on the upper edge (201) of the container can be opened.
[0025]
As described above, the container upper edge (201) is clamped by the upper nail (42) and the lower nail (41) by the closing operation of the upper nail (42), the container (200) is lifted, and the hanging piece (52).
