- FIG. 3 is a diagram showing the separation device 26 and the storage device 28 with the cover 52 open.
- the cover 52 may have a protrusion 68 protruding from the bottom surface of the cover 52.
- the protrusion 68 limits the level of the liquid, such as coolant, stored in the storage container 50.

This allows the processing debris stored in the storage container 50 to be removed from the storage container 50 without removing the separation device 26. As a result, cleaning workability can be improved.
- the opening 64 can be opened without separating the cover 52 from the storage container 50.

- a drain section 54 is provided in the storage container 50 so as to be in communication with the inside of the storage container 50.

- the guide section 78 disperses the machining waste discharged from the separation device 26 by using the top section 78A and the outer peripheral section 78B. This makes it possible to prevent the machining waste from being concentrated and accumulated inside the storage container 50. It also makes it possible to reduce the swirling up of the machining waste accumulated inside the storage container 50.

本開示は、工作機械(12)の加工により生じた加工屑を含む液体である第1液から前記加工屑を分離し、前記加工屑が分離された前記液体である第2液を前記工作機械に供給するクーラントシステム(10)である。本開示のクーラントシステムは、前記第1液を貯留する第1液槽(14)から汲み上げられた前記第1液に含まれる前記加工屑を前記第1液から分離する分離装置(26)と、前記分離装置によって分離された前記加工屑を貯留する貯留装置(28)と、を備える。前記貯留装置は、基礎上に配置され、前記加工屑が貯留される貯留容器(50)と、前記分離装置が接続され、前記貯留容器の開口部(64)を覆うカバー(52)と、を備える。
付記1に記載のクーラントシステムであって、前記貯留容器に対して前記カバーを移動可能に支持して、前記開口部を開閉する支持部材(53)を備えてもよい。これにより、カバーを移動する負荷を軽減することができる。
付記1または2に記載のクーラントシステムであって、前記カバーは、回転可能に前記貯留容器に取り付けられてもよい。これにより、貯留容器からカバーを外すことなく開口部を開閉することができる。その結果、カバーを外す作業がなくなり、作業負荷を軽減することができる。
付記1または2に記載のクーラントシステムであって、前記カバーは、前記開口部の開口面に沿ってスライド可能に前記貯留容器に取り付けられてもよい。これにより、貯留容器からカバーを外すことなく開口部を開閉することができる。その結果、カバーを外す作業がなくなり、作業負荷を軽減することができる。また、カバーと貯留容器とが蝶番等を介して連結される場合に比べて、カバーの重量が大きくても、カバーの開閉を滑らかにすることができる。
付記1に記載のクーラントシステムであって、前記カバーは、前記開口部の開口面に直交する方向に移動可能に取り付けられてもよい。これにより、貯留容器からカバーを外すことなく開口部を開閉することができる。その結果、カバーを外す作業がなくなり、作業負荷を軽減することができる。また、カバーと基礎との間から貯留容器の出し入れが可能となる。
付記1~付記5のいずれかに記載のクーラントシステムであって、前記カバーは、前記カバーの底面から突出する凸部(68)を有し、前記凸部は、前記開口部が閉じられている状態において前記貯留容器の側壁(62)における内周面の上部に向いていてもよい。これにより、貯留容器内がクーラント等の液体で満たされた状態でカバーを開けた際、クーラント等の液体が開口部から漏れることを防止することができる。
付記1~付記6のいずれかに記載のクーラントシステムは、前記貯留容器の内部と連通可能に前記貯留容器に設けられるドレン部(54)と、前記ドレン部を開閉可能なバルブ(56)とを備えてもよい。これにより、分離装置の作動中に貯留容器から加工屑およびクーラントが流出することを回避することができる。また、貯留容器の洗浄、メンテナンス作業等の期間に限って貯留容器から加工屑およびクーラント等を排出することができる。
付記1~付記7のいずれかに記載のクーラントシステムは、前記貯留容器の内部から取り出し可能に前記貯留容器の内部に配置され、前記加工屑を入れる袋(72)を備えてもよい。これにより、貯留容器から加工屑を容易に取り出すことができ、また、貯留容器の内部を清潔に保つことができる。
付記1~付記8のいずれかに記載のクーラントシステムは、前記貯留容器の内部から取り出し可能に前記貯留容器の内部に配置され、前記加工屑を捕捉する多孔性フィルタ部材(76)を備えてもよい。これにより、清掃時等にドレン部から貯留容器内の液体を抜くことで、加工屑を効率よく収集することができる。
付記1~付記9のいずれかに記載のクーラントシステムであって、前記貯留容器は、前記貯留容器の内部を前記貯留容器の外部から視認可能に形成されてもよい。これにより、カバーを開けなくても貯留容器の貯留状態を確認することができる。
付記1~付記10のいずれかに記載のクーラントシステムであって、前記分離装置から供給される前記第2液が貯留される第2液槽(16)から前記工作機械に前記第2液を圧送する第2液圧送ポンプ(22)を備えてもよい。これにより、第2液を工作機械に適切に供給することができる。
