Description

【０００１】
【産業上の利用分野】
本願発明は、金属切削屑の搬送装置の改良に関するものである。
【０００２】
【従来の技術】
ＮＣ旋盤等で切削加工をする場合、多量の金属切削屑が出るが、その金属切削屑をそのまま放置しておくと切削作業等の邪魔になる。そのため、従来からＮＣ旋盤等にコンベアを接続し、このコンベアによってＮＣ旋盤等から出された金属切削屑を所定位置まで自動的に搬送できるようにしている。
このコンベアは、例えば図９に示すように本体部ａと、本体部ａをの前端から後端を循環可動する無端環状の搬送部材ｂとを備え、この本体部ａを水平部ａ１と、水平部ａ１から上昇する上昇部ａ２とから構成するとともに、上昇部ａ２に落下防止用カバーａ３を取付け、一方、搬送部材ｂには、搬送部材ｂの上面上に幅方向に沿わして上方に突出させた板状の滑り防止部材ｂ１…ｂ１を、長手方向に所定間隔毎に複数、設けたものとし、そして、搬送部材ｂを可動させるに伴い搬送部材ｂが搬送部材ｂ上に載置した金属切削屑を本体部ａの上昇部ａ２まで搬送し、更に、搬送部材ｂが上昇部ａ２に沿って上昇し始めると滑り防止部材ｂ１が金属切削屑を下方に滑り落ちないように下方側から受けるとともに、落下防止用カバーａ３が金属切削屑を滑り防止部材ｂ１から落ちないように側方側から受け、このようにして金属切削屑を上昇部ａ２に沿って下方位置から上方位置まで搬送させる。
しかしながら、ＮＣ旋盤等から出される金属切削屑は、カール状を呈し互いに絡まって塊状となり易いものが多く、このようなカール状を呈する金属切削屑がＮＣ旋盤等からコンベアａ上に落とされると塊状となり、その状態でコンベアａの上昇部ａ２に来ると、この図９に示すように塊状となった金属切削屑が落下防止用カバーａ３に当たってしまって落下防止用カバーａ３の内側に入らず、次々に送られてくる金属切削屑が上昇部ａ２の立ち上がり基端部ａ４で滞留してしまう。又、金属切削屑が落下防止用カバーａ３に当たらない程度の大きさで流れたとしても、金属切削屑が絡まって前後に連続的に連なる場合が多く、先に流れたものが落下防止用カバーａ３に当たらずに落下防止用カバーａ３内に入ったとしても後に流れるものが落下防止用カバーａ３に当たってしまうと、既に落下防止用カバーａ３内に入ったものまで後のものに引っ張られて上昇部ａ２の立ち上がり基端部ａ４で金属切削屑が滞留してしまう。このようなことが起こると、金属切削屑全体を搬送できなくなる。
又、落下防止用カバーａ３は、金属切削屑を滑り防止部材ｂ１から落ちないようにするために必要なものであるが、その一方で、落下防止用カバーａ３のために金属切削屑が上昇部ａ２の搬送途中で絡まって詰まってしまう場合がある。このような場合には、詰まった箇所が外部から判らず、その都度、落下防止用カバーａ３全体を外して詰まった金属切削屑を取り除かなければならない。その結果、作業効率が悪くなっているという課題がある。
【０００３】
【発明が解決しようとする課題】
本願発明は、以上の実情に鑑み提案されたもので、カール状を呈する金属切削屑が上昇部を有するコンベアを円滑に搬送し得る金属切削屑搬送装置を提供することを第１の目的とする。
本願発明は、コンベアの上昇部に落下防止用カバーを設けなくても金属切削屑を円滑に搬送し得る金属切削屑搬送装置を提供することを第２の目的とする。
【０００４】
【課題を解決するための手段】
コンベア１に、搬送方向の前端から後端までの適宜位置に下方側から上方側に上昇する上昇部３３を備えることにより、コンベア１上に載置した金属切削屑をコンベア１の可動に伴い下方位置から上方位置に搬送できるようにした金属切削屑搬送装置において本願発明は、次の特徴を有するものを提供することにより上記課題を解決する。
本願第１の発明は、コンベア１上の金属切削屑をせん断し得るせん断手段２３、２４を有するせん断装置２が備えられる。
このせん断装置２は、コンベア１の上昇部３３の前方側に配設されることにより、コンベア１上に載置された金属切削屑がせん断されつつ上昇部３３に搬送されるようになされた金属切削屑処理装置である。
【０００５】
本願第２の発明は、本願第１の発明に係るせん断装置２のせん断手段２３、２４が、せん断刃２３と、せん断刃２３と対応する位置に配設された固定刃２４とを備える。又、このせん断刃２３は、コンベア１の上方側に回転可能に配設されることにより、コンベア１上に載置された金属切削屑がせん断刃２３と固定刃２４とでせん断される金属切削屑処理装置である。
【０００６】
本願第３の発明は、本願第２の発明に係るせん断刃２が、金属切削屑を引っ掛ける引っ掛け爪２５…２５を備えることにより、コンベア１上に載置された金属切削屑がせん断刃２３の回転に伴い引っ掛け部２５…２５に引っ掛けられてせん断刃２３と固定刃２４とでせん断されるようになされた金属切削屑処理装置である。
【０００７】
本願第４の発明は、本願第１〜第３の発明に係るせん断装置２が、コンベア１の上昇部３３の立ち上がり基端部３３ａに配設されてなる金属切削屑処理装置である。
【０００８】
【作用】
本願第１の金属切削屑処理装置においては、コンベア１の上昇部３３の前方側に、金属切削屑をせん断し得るせん断手段２３、２４を有するせん断装置２を備えるため、カール状をなす金属切削屑が上昇部３３に入るまでに金属切削屑を予めせん断できる。これにより、金属切削屑同士が絡みつくようなことを防止でき、金属切削屑を塊になることなく上昇部３３に送り込むことができる。
【０００９】
本願第２の金属切削屑処理装置においては、せん断装置２のせん断手段２３、２４を、コンベア１の上方側に回転可能に配設したせん断刃２３と、せん断刃２３と対応する位置に配設した固定刃２４とで構成することにより、絡まってコンベア１上に高く積まれた金属切削屑がせん断刃２３位置まで搬送されてくるとせん断刃２３と当接し、せん断刃２３の回転に巻き込まれて固定刃２４位置まで運ばれ、せん断刃２３と固定刃２４とでせん断される。これにより、コンベア１上に所定高さ以上で積まれた金属切削屑を、上昇部３３に送り込む前にせん断できる。
【００１０】
本願第３の金属切削屑処理装置においては、せん断刃２３に、金属切削屑を引っ掛ける引っ掛け爪２５…２５を備えるため、コンベア１上に載置された金属切削屑をせん断刃２３の回転に伴い引っ掛け部２５…２５に引っ掛けることができ、せん断刃２３と当接する金属切削屑を確実に固定刃２４位置まで運び、せん断刃２３と固定刃２４とでせん断できる。
【００１１】
本願第４の金属切削屑処理装置においては、せん断装置２を、コンベア１の上昇部３３の立ち上がり基端部３３ａに配設するため、前方からせん断装置２に搬送されてくる金属切削屑だけでなく、コンベア１の上昇部３３から立ち上がり基端部３３ａに落ちてきた金属切削屑をもせん断できる。これにより、仮にせん断刃２３の下方側をせん断されずに流れた金属切削屑が上昇部３３の途中で上昇部３３の立ち上がり基端部３３ａまで落ち、後に搬送されてくるものと絡まり塊になった場合でもせん断装置２によってせん断でき、立ち上がり基端部３３ａで滞留してしまうようなことを防止できる。
【００１２】
【実施例】
以下、図面に基づき、本願発明の一実施例を説明する。
図１は、本願発明の金属切削屑処理装置の一実施例の概略図である。
【００１３】
本願発明の金属切削屑処理装置は、コンベア１と、コンベア１上の金属切削屑をせん断するせん断装置２とが備えられている。
【００１４】
コンベア１は、本体部３と、本体部３を可動する搬送部材４とを備えている。本体部３は、図２に示すように上面に搬送部材４を所定方向に案内するための長溝状の案内路３１が形成されている。この案内路３１は、図１に示すように前部側（図１における右側）に略水平状に形成された水平部３２と、水平部３２の後方側（図１における左側、以下図における右側が前方を、左側が後方を夫々示す。）に水平部３２から後方側に行くに従って漸次上方側に傾斜した上昇部３３とを備えている。そして、このコンベア１は、この水平部３２の前端側がＮＣ旋盤等の切削加工機等に接続され、又は単独で使用される。尚、このコンベア１の案内路３１は、水平部３２と上昇部３３とから構成されるものに限らず、例えば上昇部３３の後方側に更に水平部３２を付設するようにしても良い。
【００１５】
搬送部材４は、図２に示すように本実施例ではコンベア１の案内路３１と略同幅からなる複数の金網部材４１…４１を、順次、互いに回動自在に接続することにより無端環状に形成されたものから構成され、その上面が金属切削屑を載置する載置部をなしている。又、この搬送部材４の載置部上には、載置した金属切削屑の滑りを防止するための複数の滑り防止部材４３…４３が備えられている。これらの滑り防止部材４３…４３各々は、載置部４２と略同幅の板状のものから構成され、載置部４２の幅方向に渡されるようにして下端が載置部４２に固定されることにより所定高さをなして載置部上に突設されている。そして、各々が載置部の長手方向に沿って所定間隔毎に並設されることにより載置部を所定間隔毎に区画している。尚、この搬送部材４は、複数の金網部材４１…４１から構成されるものに限らず、例えば一枚のゴム板から無端環状に形成されたもの、あるいは複数の金属板を接続して無端環状に形成されたものであっても良く、適宜変更できる。
【００１６】
このように形成された搬送部材４は、図１に示すように本体部３の前部及び後部に回動自在に設けられた前部ホイール３４、後部ホイール３５に巻回されることによりコンベア１の案内路３１に沿って配設され、前部ホイール３４に回転伝達可能に接続されモーター３６の始動に伴い前部ホイール３４が回転することにより搬送部材４がコンベア１の前端から後端を循環して案内路３１を後方側（図示のＸ方向）に可動するようになされている。
【００１７】
せん断装置２は、コンベア１の搬送部材４上の搬送途中の金属切削屑をせん断するためのもので、コンベア１の本体部３における案内路３１の上昇部３３の前方側に設置される。本実施例では、水平部３２と上昇部３３との境界をなす上昇部３３の立ち上がり基端部３３ａに設置されている。
【００１８】
このせん断装置２は、図６に示すように回転軸２１と、回転軸２１に取り付けられた複数のせん断刃２３と、固定刃２４とを備えている。
【００１９】
回転軸２１は、本体部３の案内路３１の立ち上がり基端部３３ａにおける左側部及び右側部各々に設置された軸受（図示せず）に軸支されることにより、図６に示すように案内路３１を搬送する搬送部材４の上方側に回動自在に架け渡されている。又、回転軸２１には、せん断刃２３を取り付けるための筒状体２１ｂが固定されている。そして、この回転軸２１は、モーター（図示せず）に回転伝達可能に接続され、モーターの始動により回転軸２１が図７において反時計方向（図示のＹ方向）に回転するとともに、筒状体２１ｂもそれに伴って同方向に回転するようになされている。
【００２０】
せん断刃２３は、本実施例では、図３(A)(B)に示すように回転軸２１の筒状体２１ｂの外周における左部及び右部に左右対称をなすように取り付けられた左刃２３ａ、２３ａ及び右刃２３ｂ、２３ｂと、これらの間に取り付けられた中刃２３ｃ、２３ｃと、くの字形状をなすように取り付けられたくの字刃２３ｄ、２３ｄとを備えている。左刃２３ａ、２３ａ、右刃２３ｂ、２３ｂ及び中刃２３ｃ、２３ｃと、くの字刃２３ｄ、２３ｄとは、図３(A) において筒状体２１ｂの外周における上側と下側との二箇所ずつ、筒状体２１ｂの周方向に交互に配設されている。これらの各刃２３ａ、２３ｂ、２３ｃ、２３ｄは、先端に刃部２６を有し、下端が筒状体２１ｂの外周に固定されることにより、刃部２６が筒状体２１ｂの径方向側に所定高さで突設されている。又、左刃２３ａ、２３ａ、右刃２３ｂ、２３ｂ及びくの字刃２３ｄ、２３ｄ各々の刃部２６は、回転軸２１の軸芯２１ａに対して各々角度Ａ、Ｂ、Ｃ、Ｄをなしている。一方、これらの各刃２３ａ、２３ｂ、２３ｃ、２３ｄは、上述のように回転軸２１の筒状体２１ｂの外周に取付けられることによって図６に示すように搬送部材４の上方側に回動自在に配設されるが、刃部２６と案内路３１との間隔は、刃部２６が搬送部材４の滑り防止部材４３…４３の上端に当たらない程度とされ、滑り防止部材４３…４３と極接近して回転するようになされている。又、本実施例では、落下防止用カバーを設けていないが、落下防止用カバーを設けた場合、各刃２３ａ、２３ｂ、２３ｃ、２３ｄは、落下防止用カバーの下面より下方側に配設され、落下防止用カバーの高さ以上の金属切削屑と当たるようになされている。
【００２１】
又、これらの左刃２３ａ、２３ａ、右刃２３ｂ、２３ｂ及びくの字刃２３ｄ、２３ｄ各々の先端には、引っ掛け爪２５…２５が備えられている。これらの引っ掛け爪２５…２５は、回転方向側の側面に側方に突出するようにして設けられ、せん断刃２３の回転に伴い搬送部材４上の搬送途中の金属切削屑を引っ掛けて巻き込めるようになされている。
【００２２】
固定刃２４は、回転するせん断刃２３とで搬送部材４上の搬送途中の金属切削屑をせん断するもので、図４(A)(B)に示すように筒状体２１ｂと同長さの板状体から構成され、後端側に全長に渡って刃部２４ａが形成されている。又、上面から下面に貫通された小判形のボルト挿通孔２４ｂ…２４ｂが複数、長手方向に沿って設けられている。そして、この固定刃２４は、固定部材２７を介して回転軸２１を軸支した上記軸受に取り付けられる。詳しくは、固定部材２７は、図５(A)(B)に示すように左部と右部各々に軸受取付部２７ａ、２７ａを備えるとともに、それらの間に複数の固定刃取付用孔２７ｃ…２７ｃを有する固定刃取付部２７ｂを備えており、この固定部材２７の軸受取付部２７ａ、２７ａ各々が左右両軸受に取付けられることにより、図３(A) に示すように固定刃取付部２７ｂが筒状体２１ｂの前部側に回転軸２１の軸芯２１ａに沿って配設されるようになされている。そして、固定刃２４は、図６に示すように刃部２４ａがせん断刃２３と対向するようにして固定部材取付部２７の下面側に、ボルト挿通孔２４ｂ…２４ｂと固定刃取付用孔２７ｃ…２７ｃとを位置合わせして各々の孔２４ｂ、２７ｃ…２４ｂ、２７ｃに上方側からボルト２８を通して下方側からナット２９を螺合させることにより前後方向位置調整可能に固定され、固定刃２４の刃部２４ａが回転軸２１の軸芯２１ａと同じ高さ位置で軸芯２１ａに沿って配位される。これにより、固定刃２４の刃部２４ａとせん断刃２３の刃部２６…２６とがすくい角Ａ、Ｂ、Ｃ、Ｄを形成するようになされている。尚、この固定刃２４の固定方法は、この態様のものに限らず、適宜変更でき、例えば固定刃取付部２６ｂに溶接等により直接固定するようにしても良い。又、固定刃２４の数は、一つだけ設けるものに限らず、二つ以上設けるようにしても良い。一方、固定刃２４の配設位置についても、特に限定されない。
【００２３】
次に、この装置の機能について説明する。
まず、コンベア１を始動させて搬送部材４を案内部３１に沿って可動させるとともに、せん断装置２を始動させてせん断刃２３を回転させる。そして、この状態で、ＮＣ旋盤等の切削加工機から出された金属切削屑は、順次コンベア１の前端側から搬送部材４上に載せられ、案内部３１の水平部３２を後方側に搬送される。そして、金属切削屑がせん断装置２を通過する際、搬送部材４の滑り防止部材４３の上端より下方側になっている金属切削屑はせん断刃２３の下方を通過するが、滑り防止部材４３の上端より上方側に突出して載置された金属切削屑はせん断刃２３に当たる。その際、せん断刃２３が左刃２３ａ、右刃２３ｂ、中刃２３ｃ、くの字刃２３ｄからなる分断した複数の刃から構成されているため、せん断刃２３の回転に伴い金属切削屑が各々の刃に容易に巻き付けられる。しかも、左刃２３ａ、右刃２３ｂ及びくの字刃２３ｄに引っ掛け爪２５…２５が備えられているため、各刃に巻き付かない場合にも、引っ掛け爪２５…２５が確実に引っ掛けることができる。
【００２４】
そして、せん断刃２３に巻き付き、あるいは引っ掛け爪２５…２５に引っ掛けられた金属切削屑は、固定刃２４位置まで運ばれるとせん断刃２３と固定刃２４で短くせん断される。又、金属切削屑はカール状を呈し互いに絡みついている場合が多く、このような場合には、滑り防止部材４３より上方側に突出している一部の金属切削屑がせん断刃２３に巻き付たりすると、その下部側の金属切削屑も引っ張られ、塊になった金属切削屑全体がせん断されることになる。更に、せん断刃２３に当たることなく、せん断刃２３の下方側を流れた金属切削屑も、後に流れてくる金属切削屑がせん断刃２３に巻き付たりすると、その後の金属切削屑と一部が絡まっていたり、あるいは、後の金属切削屑がせん断刃２３に巻き付く等する際に絡まり、後の金属切削屑に引き戻されてせん断されることになる。
【００２５】
せん断された金属切削屑、あるいは、せん断されずにせん断刃２３の下方側を流れた金属切削屑は、上昇部３３に送られ、滑り防止部材４３に下方側から受けられながら上昇部３３を搬送される。又、仮にせん断刃２３の下方側を流れた金属切削屑が上昇部３３の途中で、何らかの理由で下方に落ちた場合には、上昇部３３の立ち上がり基端部３３ａで、後に流れてくる金属切削屑と絡まり塊になって滞留してしまい、再度上昇部３３を上がることができないが、この実施例のようにせん断装置２を、上昇部３３の立ち上がり基端部３３ａに設置しておくことにより、せん断刃２３が上昇部３３の立ち上がり基端部３３ａに滞留した金属切削屑が回転に伴って巻付け等でき、それらの金属切削屑をせん断できる。これにより、落ちてきた金属切削屑を、上昇部３３の立ち上がり基端部３３ａに溜めることなく、せん断でき、上昇部３３を円滑に搬送できるものとなる。従って、金属切削屑が上昇部３３から落ちてきても差し支えのないものにでき、従来のように上昇部３３に落下防止用カバーを設けることが不要となり、又、落下防止用カバーを設けた場合の上昇部３３における金属切削屑の詰まりも解消できる。
【００２６】
コンベア１の後端まで搬送されてきた金属切削屑は、コンベア１の後端から容器等の所定場所に落とされ、あるいは、他のせん断装置に落とされて更に細かくせん断される等されて処理される。
【００２７】
以上のようにして搬送することにより、ＮＣ旋盤等の切削加工機から出されたカール状を呈し互いに絡みついて塊となり易い金属切削屑をコンベア１の上昇部３３に入る前に細かくせん断するため、コンベア１の上昇部３３に円滑に入れることができ、又、前後に流れる金属切削屑同士が絡まることを防止でき、後の金属切削屑によって先の金属切削屑が引っ張られて下方側に落とされるようなことも防止できる。従って、塊となり易い金属切削屑を、コンベア１の上昇部３３を円滑に搬送できる。
【００２８】
尚、本実施例では、せん断装置２を、上昇部３３の立ち上がり基端部３３ａに設置しているが、水平部３２であれば金属切削屑を上昇部３３に入る前に細かくせん断でき、適宜変更できる。又、せん断装置２は一台だけ設けるものに限らず、立ち上がり基端部３３ａと、水平部３２の適宜位置に各一台設ける等、水平部３２に二台以上設けても良い。
【００２９】
又、本実施例では、せん断装置２におけるせん断手段として回転するせん断刃２３と固定刃２４とで行うようにしているが、この態様のものに限らず、例えば外周に複数の突起刃を有する回転部材を二つ、互いに反対方向に回転するに伴い突起刃同士が噛み合うように配設し、その突起刃同士が噛み合う際にせん断するようなものであっても良い。更に、本実施例においては、せん断装置２のせん断刃２３を複数の分断した刃２３ａ、２３ｂ、２３ｃ、２３ｄからすくい角を形成し、円滑にせん断できるようにするとともに、各刃に引っ掛け爪２５…２５を付設したものとしているが、例えば図７に示すように板状からなる複数のせん断刃２３…２３を、回転軸２１の軸芯に沿って放射状に配設するようにし、更には、それらのせん断刃２３…２３に側面に引っ掛け爪２５…２５を付設し、あるいは図８) に示すように螺旋状をなす複数のせん断刃２３…２３を取り付けてすくい角を形成するようにし、更には、それらのせん断刃２３…２３に側面に引っ掛け爪２５…２５を付設するようにしても良い。
【００３０】
一方、本実施例のコンベア１における上昇部３３には、落下防止用カバーを設けていないが、落下防止用カバーを設けた従来のものを利用しても良い。
【００３１】
【発明の効果】
本願第１の発明は、カール状をなす金属切削屑を上昇部に入るまでに予めせん断できる。これにより、金属切削屑同士が絡みつくようなことを防止でき、金属切削屑を塊になることなく上昇部に送り込むことができる。
【００３２】
本願第２の発明は、本願第１の発明の効果に加え、絡まってコンベア上に高く積まれた金属切削屑を回転しているせん断刃に当接させ、せん断刃の回転に巻き込んで固定刃位置まで運び、せん断刃と固定刃とでせん断できる。これにより、コンベア上に所定高さ以上で積まれた金属切削屑を上昇部に送り込む前にせん断でき、コンベアの上昇部に金属切削屑を所定高さ以下にして送りこむことができる。
【００３３】
本願第３の発明は、本願第２の発明の効果に加え、コンベア上に載置された金属切削屑をせん断刃の回転に伴い引っ掛け部に引っ掛けることができ、せん断刃と当接する金属切削屑を確実に固定刃位置まで運び、せん断刃と固定刃とで確実にせん断できる。
【００３４】
本願第４の発明は、本願第１、第２又は、第３の発明の効果に加え、せん断装置によって、前方からせん断装置に搬送されてくる金属切削屑だけでなく、コンベアの上昇部の途中から立ち上がり基端部に落ちてきた金属切削屑をもせん断できる。これにより、仮にせん断刃の下方側をせん断されずに流れた金属切削屑が上昇部の途中で、何らかの理由で下方に落ちて上昇部の立ち上がり基端部で絡まり塊になって滞留してしまうようなことを防止できる。従って、１台のせん断装置で、順次搬送されてくる金属切削屑を残らず、確実に上昇部を有するコンベアの後端まで搬送できる。

[Industrial application fields]
The present invention relates to an improvement of a metal cutting scrap conveying device.
[0002]
[Prior art]
When cutting with an NC lathe or the like, a large amount of metal cutting waste is produced. However, if the metal cutting waste is left as it is, it will interfere with cutting work and the like. For this reason, conventionally, a conveyor is connected to an NC lathe or the like, and the metal cutting waste discharged from the NC lathe or the like can be automatically conveyed to a predetermined position by this conveyor.
For example, as shown in FIG. 9, the conveyor includes a main body part a and an endless annular conveying member b that circulates from the front end to the rear end of the main body part a. And a rising prevention part a2 is attached to the ascending part a2, and the conveying member b protrudes upward along the width direction on the upper surface of the conveying member b. A plurality of plate-like anti-slip members b1... B1 provided at predetermined intervals in the longitudinal direction, and the metal that the conveying member b is placed on the conveying member b as the conveying member b is moved. When the cutting scrap is conveyed to the ascending portion a2 of the main body portion a and the conveying member b starts to rise along the ascending portion a2, the anti-slip member b1 receives the metal cutting scrap from the lower side so as not to slide down. In addition, the fall prevention cover a3 Offcut receiving laterally side so as not to fall from the anti-slip member b1 and thus the metal cutting chips along the rising portion a2 is conveyed from the lower position to the upper position.
However, there are many metal cutting scraps that come out of an NC lathe or the like that are curled and tend to be tangled with each other. In this state, when it comes to the ascending portion a2 of the conveyor a, the lump of metal cutting waste as shown in FIG. 9 hits the fall prevention cover a3 and does not enter the fall prevention cover a3 one after another. The metal cutting waste sent to the stagnation stays at the rising base end portion a4 of the rising portion a2. Moreover, even if the metal cutting waste flows in such a size that it does not hit the fall prevention cover a3, the metal cutting waste is often tangled and continuously connected back and forth. Even if it falls into the fall prevention cover a3 without hitting a3, if something that flows later hits the fall prevention cover a3, it will be pulled by the later one up to the one that has already entered the fall prevention cover a3. The metal cutting waste stays at the rising base end a4 of a2. When this happens, the entire metal cutting waste cannot be conveyed.
The fall prevention cover a3 is necessary to prevent the metal cutting waste from falling from the anti-slip member b1, while the metal cutting waste is raised by the fall prevention cover a3. There is a case where clogging occurs due to entanglement during the conveyance of a2. In such a case, the clogged portion cannot be determined from the outside, and each time the fall prevention cover a3 is removed, the clogged metal cutting waste must be removed. As a result, there is a problem that work efficiency is deteriorated.
[0003]
[Problems to be solved by the invention]
The present invention has been proposed in view of the above circumstances, and a first object thereof is to provide a metal cutting waste conveyance device capable of smoothly conveying a curled metal cutting waste having a rising portion. .
A second object of the present invention is to provide a metal cutting waste transporting apparatus that can smoothly transport metal cutting waste without providing a fall prevention cover at the rising portion of the conveyor.
[0004]
[Means for Solving the Problems]
By providing the conveyor 1 with a rising portion 33 that rises from the lower side to the upper side at an appropriate position from the front end to the rear end in the transport direction, the metal cutting waste placed on the conveyor 1 is moved downward as the conveyor 1 moves. This invention solves the said subject by providing what has the following characteristics in the metal cutting waste conveyance apparatus which enabled it to convey to an upper position from a position.
1st invention of this application is provided with the shearing apparatus 2 which has the shearing means 23 and 24 which can shear the metal cutting waste on the conveyor 1. As shown in FIG.

[0023]
Next, the function of this apparatus will be described.
First, the conveyor 1 is started to move the conveying member 4 along the guide portion 31 and the shearing device 2 is started to rotate the shearing blade 23. Then, in this state, the metal cutting waste discharged from a cutting machine such as an NC lathe is sequentially placed on the conveying member 4 from the front end side of the conveyor 1 and conveyed to the rear side through the horizontal portion 32 of the guide portion 31. The When the metal cutting waste passes through the shearing device 2, the metal cutting waste that is below the upper end of the slip prevention member 43 of the conveying member 4 passes below the shear blade 23, but the slip prevention member 43 The metal cutting waste placed so as to protrude upward from the upper end hits the shearing blade 23. At that time, since the shearing blade 23 is composed of a plurality of divided blades including a left blade 23a, a right blade 23b, a middle blade 23c, and a dogleg 23d, each of the metal cutting wastes is generated along with the rotation of the shear blade 23. Can be easily wrapped around the blade. Moreover, since the left blade 23a, the right blade 23b, and the dog-legged blade 23d are provided with the hooking claws 25 ... 25, the hooking claws 25 ... 25 can be reliably hooked even when they are not wound around the respective blades. .
[0024]
And the metal cutting waste wound around the shearing blade 23 or hooked on the hooking claws 25 ... 25 is sheared shortly by the shearing blade 23 and the fixed blade 24 when it is carried to the position of the fixed blade 24. Further, the metal cutting scraps are often curled and entangled with each other. In such a case, some of the metal cutting scraps protruding upward from the anti-slip member 43 are wound around the shearing blade 23. Then, the metal cutting waste on the lower side is also pulled, and the whole metal cutting waste in a lump is sheared. Furthermore, even if the metal cutting waste that flows below the shearing blade 23 without hitting the shearing blade 23 is wrapped around the shearing blade 23, a part of the subsequent metal cutting waste is entangled. Or entangled when the subsequent metal cutting wraps around the shearing blade 23, etc., and is pulled back and sheared by the subsequent metal cutting swarf.
[0025]
The sheared metal cutting waste or the metal cutting waste that has flowed below the shearing blade 23 without being sheared is sent to the rising portion 33 and conveyed to the rising portion 33 while being received by the anti-slip member 43 from below. Is done. Further, if the metal cutting waste that flows below the shearing blade 23 falls down for some reason in the middle of the rising portion 33, the metal that flows later at the rising base end portion 33 a of the rising portion 33. Although it becomes a lump of entanglement with cutting waste and stays, the ascending part 33 cannot be raised again, but the shearing device 2 should be installed at the rising base end 33a of the ascending part 33 as in this embodiment. Thus, the metal cutting waste accumulated in the rising base end portion 33a of the rising portion 33 by the shearing blade 23 can be wound with rotation, and the metal cutting waste can be sheared. As a result, the falling metal cutting waste can be sheared without accumulating in the rising base end portion 33a of the rising portion 33, and the rising portion 33 can be smoothly conveyed. Therefore, even if the metal cutting waste falls from the rising portion 33, it can be made safe, and it is not necessary to provide a falling prevention cover on the rising portion 33 as in the prior art, and when a falling prevention cover is provided. The clogging of metal cutting scraps in the rising portion 33 can be eliminated.
[0026]
The metal cutting waste conveyed to the rear end of the conveyor 1 is dropped from the rear end of the conveyor 1 to a predetermined place such as a container, or dropped to another shearing device and further finely sheared. The
[0027]
By carrying as described above, the metal cutting scraps that are curled out from a cutting machine such as an NC lathe and tend to be entangled with each other to form a lump are finely sheared before entering the ascending portion 33 of the conveyor 1, It can be smoothly put into the ascending portion 33 of the conveyor 1 and can prevent the metal cutting waste flowing back and forth from being entangled, and the previous metal cutting waste is pulled by the subsequent metal cutting waste and dropped downward. This can also be prevented. Therefore, the metal cutting waste which tends to become a lump can be smoothly conveyed through the rising portion 33 of the conveyor 1.
[0028]
In this embodiment, the shearing device 2 is installed at the rising base end 33a of the ascending portion 33. However, if the horizontal portion 32, the metal cutting waste can be finely sheared before entering the ascending portion 33. Can change. Also, the shearing device 2 is not limited to a single device, and two or more shearing devices 2 may be provided in the horizontal portion 32, such as one each at an appropriate position of the rising base end portion 33a and the horizontal portion 32.
[0029]
Further, in this embodiment, the shearing device 2 is operated with the shearing blade 23 and the fixed blade 24 that rotate as the shearing means. However, the present invention is not limited to this mode. For example, the rotation having a plurality of projecting blades on the outer periphery. Two members may be arranged so that the protruding blades mesh with each other as they rotate in opposite directions, and shear when the protruding blades mesh with each other. Furthermore, in the present embodiment, a rake angle is formed from the plurality of divided blades 23a, 23b, 23c, and 23d of the shearing blade 23 of the shearing device 2 so that the shearing can be smoothly performed and the hook 25 is hooked on each blade. 25 is provided, for example, as shown in FIG. 7, a plurality of plate-like shearing blades 23... 23 are arranged radially along the axis of the rotary shaft 21. Hook claws 25 ... 25 are attached to the side surfaces of the shear blades 23 ... 23, or a plurality of spiral shear blades 23 ... 23 are attached to form a rake angle as shown in FIG. The hooks 25... 25 may be attached to the side surfaces of the shear blades 23.
[0030]
On the other hand, the rising portion 33 of the conveyor 1 of this embodiment is not provided with a fall prevention cover, but a conventional one provided with a fall prevention cover may be used.
[0031]
【The invention's effect】
According to the first aspect of the present invention, the curled metal cutting waste can be sheared in advance before entering the rising portion. Thereby, it can prevent that metal cutting waste gets entangled, and can send metal cutting waste to a raise part, without becoming a lump.
[0032]
In addition to the effects of the first invention of the present application, the second invention of the present application brings the metal cutting waste tangled up and stacked high on the conveyor into contact with the rotating shearing blade, and is wound into the rotation of the shearing blade and fixed blade. It can be carried to a position and sheared with a shearing blade and a fixed blade. Thereby, it can shear before sending the metal cutting waste piled up on the conveyor more than predetermined height to a raise part, and can send metal cutting waste below a predetermined height to the raising part of a conveyor.
[0033]
In addition to the effect of the second invention of the present application, the third invention of the present application is capable of hooking the metal cutting waste placed on the conveyor onto the hooking portion with the rotation of the shearing blade and contacting the shearing blade. Can be securely carried to the fixed blade position and reliably sheared by the shear blade and the fixed blade.
[0034]
In addition to the effects of the first, second or third invention of the present application, the fourth invention of the present application is not only the metal cutting waste conveyed to the shearing device from the front by the shearing device, but also in the middle of the rising portion of the conveyor. It is possible to shear metal cutting scraps rising from the base end and falling to the base end. As a result, the metal cutting waste that flows without being sheared on the lower side of the shearing blade falls down for some reason in the middle of the ascending part and stays in a tangled mass at the rising base end of the ascending part. This can be prevented. Therefore, it is possible to reliably transport the metal cutting scraps that are sequentially transported to the rear end of the conveyor having the ascending portion with a single shearing device.
