Description

本発明は、タンク内の洗浄液を濾過処理する濾過装置が排出する汚液を受け取る汚液受取装置及び汚液受取方法に関する。   BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a waste liquid receiving apparatus and a waste liquid receiving method for receiving waste liquid discharged by a filtering device that filters a washing liquid in a tank.

工作機械は工具を自動交換することで多種類の加工を実行する。工作機械は工具収納部と工具交換装置を備えている。工具収納部は複数種類の工具を工具ホルダに保持した状態で収納し、必要な工具を交換位置に送り出す。工具交換装置は交換位置で工具を受け取って次に主軸に装着する工具を交換位置に搬送し、該工具を工作機械の主軸に取付ける。   A machine tool carries out various types of machining by automatically changing tools. The machine tool comprises a tool storage and a tool changer. The tool storage unit stores a plurality of types of tools in a state of being held by the tool holder, and sends out the necessary tools to the replacement position. The tool changer receives the tool at the change position, and then conveys the tool to be mounted on the spindle to the change position and mounts the tool on the spindle of the machine tool.

主軸は加工室の内部に位置している。加工室の内部には加工によって発生した切粉が存在する。切粉は主軸に取付ける前の工具ホルダに付着することがある。この場合、切粉の影響で、工具は主軸に対して正しく位置決めできない。例えば、工具は偏心した状態で回転し、加工精度が低下する。切粉の付着量が多い場合、工具は主軸に取付けできない。   The spindle is located inside the processing chamber. Chips generated by processing exist inside the processing chamber. Chips may stick to the tool holder prior to mounting on the spindle. In this case, the tool can not be positioned correctly with respect to the spindle due to the influence of chips. For example, the tool rotates in an eccentric state, and the processing accuracy decreases. The tool can not be mounted on the spindle when there is a large amount of attached chips.

このような問題を解決する為、工作機械は洗浄液（冷却液）を用いて工具を洗浄する。工作機械は、加工作業と工具交換の時、工具の内側と外側に洗浄液を噴出する。これによって、工具に付着している切粉を洗い落とす。工作機械は、使用済みの洗浄液を貯留するタンクを備え、タンク内の洗浄液を濾過処理した後、再び工具の洗浄に用いる。   In order to solve such a problem, the machine tool cleans the tool using a cleaning solution (coolant). The machine tool ejects a cleaning solution to the inside and the outside of the tool at the time of machining operation and tool change. By this, the chips adhering to the tool are washed away. The machine tool is provided with a tank for storing used cleaning fluid, and after filtering the cleaning fluid in the tank, it is used again for tool cleaning.

例えば、特許文献１のクーラント清浄装置では、いわゆるトルネード式浄化装置を用いて浄化済クーラントの清浄度を向上させると共に、クーラント清浄装置本体への脱着が自在である密封容器に微小な異物を収容することで、当該異物の破棄作業を容易にすることが開示されている。   For example, in the coolant cleaning device of Patent Document 1, the so-called tornado type cleaning device is used to improve the cleanliness of the purified coolant, and the minute foreign matter is accommodated in the sealed container which can be freely desorbed to the coolant cleaning device main body. It is disclosed that the foreign material disposal operation is facilitated.

特開２００５−３４９３０号公報JP 2005-34930 A

しかし、特許文献１のクーラント清浄装置においては、トルネード式浄化装置が濾過する異物は液体を多く含むので、異物を収容する密封容器がすぐ満杯になる。従って、ユーザは頻繁に密封容器を手入れする必要があるので、メンテナンスが煩わしい。   However, in the coolant cleaning device of Patent Document 1, since the foreign matter to be filtered by the tornado type purification device contains a large amount of liquid, the sealed container for containing the foreign matter is immediately filled up. Therefore, the user is required to frequently maintain the sealed container, which makes maintenance difficult.

また、特許文献１のクーラント清浄装置においては、トルネード式浄化装置から吐出した清浄度の低いクーラントを分離槽が収容し、油分を浮遊させつつスラッジを沈殿させることによって、清浄度の高いクーラントを回収している。   Further, in the coolant cleaning device of Patent Document 1, the coolant having a low degree of cleanliness discharged from the tornado type purification device is contained in the separation tank, and the coolant having a high degree of cleanliness is recovered by suspending sludge while suspending oil components. doing.

しかしながら、トルネード式浄化装置から吐出する低い清浄度のクーラントは勢い強く分離槽に流れ込むので、分離槽内でスラッジが舞い上がる。従って、清浄度の高いクーラントの回収は容易でない。   However, since the low cleanliness coolant discharged from the tornado type purification device flows vigorously into the separation tank, the sludge rises in the separation tank. Therefore, recovery of a highly clean coolant is not easy.

本発明は、斯かる事情に鑑みてなされたものであり、濾過処理の汚液を収容する収容部内の沈殿物が収容部に流れ込む汚液によって舞い上がることに起因する弊害を防ぐことができる汚液受取装置及び汚液受取方法を提供することを目的とする。また、収容部のメンテナンスの手間を軽減でき、かつ簡単な構造にて汚液から洗浄液を回収できる汚液受取装置及び汚液受取方法を提供することを目的とする。   This invention is made in view of such a situation, and can prevent the bad effect resulting from the precipitate in the accommodating part which accommodates the contaminated liquid of filtration processing soaring by the contaminated liquid which flows in into an accommodating part. The purpose is to provide a receiving device and a method for receiving a waste liquid. Another object of the present invention is to provide a waste liquid receiving apparatus and a waste liquid receiving method capable of reducing the time and effort of maintenance of the storage unit and recovering the washing liquid from the waste liquid with a simple structure.

Therefore, it is possible to reduce the time and effort of maintenance for disposing of the contaminated fluid accumulated in the storage portion.

本発明に係る汚液受取装置は、前記濾過装置からの汚液を前記収容部内に案内する案内部を備えることを特徴とする。   The waste liquid receiving apparatus according to the present invention is characterized by including a guide portion for guiding the waste liquid from the filtering device into the storage portion.

本発明にあっては、前記案内部が前記濾過装置からの汚液を前記収容部内に案内する。   In the present invention, the guide portion guides the dirty fluid from the filtration device into the storage portion.

本発明に係る汚液受取装置は、前記案内部は、前記収容部の上方に位置し、筒状をなしており、内側面に沿って汚液を流して前記収容部に案内することを特徴とする。   In the waste liquid receiving apparatus according to the present invention, the guide part is located above the storage part, has a cylindrical shape, and flows the waste liquid along the inner side to guide it to the storage part. I assume.

本発明にあっては、前記濾過装置からの汚液が前記案内部の内側面に沿って流れ、前記収容部内に流れ込む。   In the present invention, the dirty fluid from the filtration device flows along the inner side surface of the guide portion and flows into the storage portion.

（実施の形態１）
図１は実施の形態１に係る工具洗浄装置の要部構成図である。実施の形態１に係る工具洗浄装置１００は、タンク１１と、スーパークリーンタンク（以下、ＳＣタンクと言う）１１０と、第１ポンプ６１と、第２ポンプ６０とを備える。 Embodiment 1
FIG. 1 is a main part configuration diagram of a tool cleaning device according to a first embodiment. The tool cleaning apparatus 100 according to the first embodiment includes a tank 11, a super clean tank (hereinafter, referred to as an SC tank) 110, a first pump 61, and a second pump 60.

タンク１１は、工具の洗浄に供給すべき洗浄液、又は使用済みの洗浄液を貯留する。ＳＣタンク１１０は、タンク１１の洗浄液に濾過処理を施した高精度洗浄液を貯留する。   The tank 11 stores the cleaning solution to be supplied for cleaning the tool or the used cleaning solution. The SC tank 110 stores a high precision cleaning liquid obtained by filtering the cleaning liquid of the tank 11.

工具洗浄装置１００は、タンク１１内の洗浄液に対して一次的に濾過処理を施す第１フィルタ６２を備えている。第１ポンプ６１は、タンク１１内の洗浄液を吸い上げ、第１フィルタ６２に送る。   The tool cleaning apparatus 100 is provided with a first filter 62 that primarily performs a filtering process on the cleaning liquid in the tank 11. The first pump 61 sucks up the cleaning liquid in the tank 11 and sends it to the first filter 62.

第２ポンプ６０はＳＣタンク１１０内の高精度洗浄液を吸い上げ、加工室４０内に送り出す。第２ポンプ６０の吐出側は、加工室４０内側の洗浄液ノズル３０に接続している。第２ポンプ６０は、ＳＣタンク１１０内の高精度洗浄液を吸い上げ、洗浄液ノズル３０から加工中の工具と加工物に噴射する。洗浄液は加工室４０内で加工中の工具と加工物を洗浄・冷却する。   The second pump 60 sucks up the high precision cleaning fluid in the SC tank 110 and sends it out into the processing chamber 40. The discharge side of the second pump 60 is connected to the cleaning solution nozzle 30 inside the processing chamber 40. The second pump 60 sucks up the high precision cleaning liquid in the SC tank 110 and jets it from the cleaning liquid nozzle 30 to a tool and a workpiece being processed. The cleaning solution cleans and cools the tool and the workpiece being processed in the processing chamber 40.

例えば、第１フィルタ６２はサイクロン式濾過装置である。第１フィルタ６２は、遠心分離処理によって洗浄液内の切粉等の汚物を取り除く。第１フィルタ６２は、遠心分離処理を経て濾過された洗浄液を、第１流路８１を介して貯留槽５０に送る。第１流路８１は、一端が第１フィルタ６２に接続しており、他端が貯留槽５０に接続している。第１流路８１は、第２フィルタ６６を有している。第１流路８１は、第２フィルタ６６と貯留槽５０の間に逆止弁６７を有している。第２フィルタ６６は、第１フィルタ６２で濾過された洗浄液に対して再び濾過処理を施す。   For example, the first filter 62 is a cyclone type filtration device. The first filter 62 removes dirt such as chips in the washing solution by centrifugation. The first filter 62 sends the cleaning liquid filtered through the centrifugal separation process to the reservoir 50 via the first flow path 81. One end of the first flow path 81 is connected to the first filter 62, and the other end is connected to the storage tank 50. The first flow path 81 has a second filter 66. The first flow path 81 has a check valve 67 between the second filter 66 and the storage tank 50. The second filter 66 filters the cleaning liquid filtered by the first filter 62 again.

従って、タンク１１の洗浄液は、第１フィルタ６２での一次濾過処理後、第２フィルタ６６にて二次濾過処理を経て貯留槽５０に流れ込む。貯留槽５０は、一次濾過処理と二次濾過処理を経た洗浄液（高精度洗浄液）を貯留する。   Therefore, after the primary filtration process by the first filter 62, the cleaning liquid in the tank 11 flows through the secondary filtration process by the second filter 66 and flows into the storage tank 50. The storage tank 50 stores the cleaning liquid (high precision cleaning liquid) that has undergone the primary filtration process and the secondary filtration process.

第１流路８１には第２流路８２が接続している。第２流路８２は、一端が逆止弁６７と貯留槽５０の間に接続しており、他端が加工室４０内の一方のノズル３０に接続している。前記ノズル３０は、第２フィルタ６６での濾過処理を経た高精度洗浄液を工具と加工物に噴射する。第２流路８２は第２流路弁６９を備えている。従って、第２流路弁６９を開けることによって、前記ノズル３０へ高精度洗浄液を送ることができる。   A second flow passage 82 is connected to the first flow passage 81. One end of the second flow path 82 is connected between the check valve 67 and the storage tank 50, and the other end is connected to one nozzle 30 in the processing chamber 40. The nozzle 30 jets the high-precision cleaning liquid, which has been subjected to the filtering process by the second filter 66, to the tool and the workpiece. The second flow passage 82 is provided with a second flow passage valve 69. Therefore, by opening the second flow path valve 69, high precision cleaning liquid can be sent to the nozzle 30.

貯留槽５０は高精度洗浄液を貯留する。例えば、貯留槽５０が満杯になると、高精度洗浄液は第４流路８３を介してＳＣタンク１１０に流れ込む。第４流路８３は、一端が貯留槽５０に接続しており、他端がＳＣタンク１１０にて開口している。第４流路８３は第４流路弁５１を備えている。従って、第４流路弁５１を開けることによって、貯留槽５０からＳＣタンク１１０へ高精度洗浄液を送ることができる。   The storage tank 50 stores the high precision cleaning liquid. For example, when the storage tank 50 is full, the high-precision cleaning solution flows into the SC tank 110 via the fourth flow path 83. One end of the fourth flow path 83 is connected to the storage tank 50, and the other end is open at the SC tank 110. The fourth flow path 83 is provided with a fourth flow path valve 51. Therefore, by opening the fourth flow path valve 51, the highly accurate cleaning liquid can be sent from the storage tank 50 to the SC tank 110.

第２ポンプ６０はＳＣタンク１１０内の高精度洗浄液を吸い上げ、第５流路８４を介して、加工室４０に送る。第５流路８４は、一端が第２ポンプ６０に接続しており、他端が加工室４０内の他のノズル３０に接続している。前記ノズル３０は、第２ポンプ６０が吸い上げた高精度洗浄液を工具と加工物に噴射する。第５流路８４は第５流路弁６８を備えている。従って、第５流路弁６８を開けることによって、前記ノズル３０へ高精度洗浄液を送ることができる。   The second pump 60 sucks up the high precision cleaning fluid in the SC tank 110 and sends it to the processing chamber 40 via the fifth flow path 84. One end of the fifth flow path 84 is connected to the second pump 60, and the other end is connected to another nozzle 30 in the processing chamber 40. The nozzle 30 jets the high-precision cleaning solution sucked by the second pump 60 to the tool and the workpiece. The fifth flow passage 84 is provided with a fifth flow passage valve 68. Therefore, by opening the fifth flow path valve 68, high precision cleaning liquid can be sent to the nozzle 30.

加工室４０は内部に、加工物を加工するための加工テーブル（図示略）を備えている。加工室４０は内側に複数の前記ノズル３０を備えており、ノズル３０は第２流路８２又は第５流路８４が送る高精度洗浄液を加工室４０内で加工中の工具と加工物に噴射する。洗浄液は工具と加工物を洗浄・冷却する。   The processing chamber 40 internally includes a processing table (not shown) for processing a workpiece. The processing chamber 40 is provided with the plurality of nozzles 30 inside, and the nozzle 30 sprays the high-precision cleaning liquid delivered by the second flow path 82 or the fifth flow path 84 to the tool and workpiece being processed in the processing chamber 40. Do. The cleaning solution cleans and cools the tool and the workpiece.

第１フィルタ６２は、遠心分離処理にて取り除いた汚物を含む汚液をドレンポッド６３に送る。ドレンポッド６３は、例えば、円筒形状をなしており、第１フィルタ６２に接続する流入口６３１を有している。ドレンポッド６３は流入口６３１を介して第１フィルタ６２が吐出する汚液を受け入れて一時的に収容する。ドレンポッド６３は、排出口６３２を介して汚液を排出する。ドレンポッド６３の下側には汚液受取装置７０が位置している。ドレンポッド６３の排出口６３２は排出路８５に接続している。排出路８５は、一端がドレンポッド６３の排出口６３２に接続しており、他端が汚液受取装置７０に延びている。排出路８５は排出口弁６４を備えている。従って、排出口弁６４を開けることによって、ドレンポッド６３から汚液受取装置７０へ汚液を排出できる。   The first filter 62 sends to the drain pod 63 the filth containing the filth removed by the centrifugal separation process. The drain pod 63 has, for example, a cylindrical shape, and has an inlet 631 connected to the first filter 62. The drain pod 63 receives and temporarily stores the waste fluid discharged by the first filter 62 through the inlet 631. The drain pod 63 drains the dirty fluid through the outlet 632. Below the drain pod 63, the waste liquid receiving device 70 is located. The discharge port 632 of the drain pod 63 is connected to the discharge passage 85. One end of the discharge path 85 is connected to the discharge port 632 of the drain pod 63, and the other end extends to the dirty water receiving device 70. The discharge passage 85 is provided with a discharge valve 64. Therefore, by opening the outlet valve 64, the dirty fluid can be discharged from the drain pod 63 to the dirty fluid receiving device 70.

図２は実施の形態１に係る汚液受取装置７０の付近を拡大して表示した模式図である。汚液受取装置７０は排出路８５から流れ込む汚液を収容する収容部７１を備えている。収容部７１は切粉より小さい孔を有する網筒体である。例えば収容部７１は円筒形状をなしており、上部の一面が開放口７２であり、下部に底面７３を有している。収容部７１は、少なくとも下部がタンク１１の洗浄液中に浸かっている。望ましくは、収容部７１の全体がタンク１１の洗浄液中に浸かっていれば良い。   FIG. 2 is a schematic view showing the vicinity of the waste liquid receiving apparatus 70 according to the first embodiment in an enlarged manner. The liquid receiving apparatus 70 is provided with a container 71 for containing the liquid flowing from the discharge passage 85. The housing portion 71 is a mesh cylinder having a hole smaller than the chips. For example, the housing portion 71 has a cylindrical shape, one surface of the upper portion is an opening 72, and the lower surface has a bottom surface 73. At least the lower portion of the housing portion 71 is immersed in the cleaning liquid of the tank 11. Desirably, the entire storage unit 71 may be immersed in the cleaning liquid of the tank 11.

第１フィルタ６２が吐出した汚液は、排出路８５を介して汚液受取装置７０（収容部７１）に流入する。排出路８５の他端８５１は収容部７１の開放口７２の付近にて開口しており、第１フィルタ６２からの汚液は適確に収容部７１内に入る。斯かる汚液は収容部７１の底面７３上に沈殿し、汚液が含む洗浄液は収容部７１の網を介してタンク１１内に流れる。従って、汚液中の洗浄液を回収できる。   The dirty fluid discharged by the first filter 62 flows into the dirty fluid receiving device 70 (storage part 71) through the discharge passage 85. The other end 851 of the discharge path 85 is opened in the vicinity of the opening 72 of the accommodating portion 71, and the dirty fluid from the first filter 62 appropriately enters the accommodating portion 71. Such waste solution is deposited on the bottom surface 73 of the storage unit 71, and the cleaning solution contained in the waste solution flows into the tank 11 through the mesh of the storage unit 71. Therefore, the cleaning liquid in the contaminated fluid can be recovered.

汚液から回収できた洗浄液はタンク１１に溜まり、第１ポンプ６１が再び工具の洗浄・冷却に供給する。従って、収容部７１に溜まった汚液を廃棄するメンテナンスの手間を軽減できる。   The cleaning solution which can be recovered from the waste liquid is accumulated in the tank 11, and the first pump 61 supplies the cleaning and cooling of the tool again. Therefore, it is possible to reduce the time and effort of maintenance for disposing of the contaminated fluid accumulated in the accommodating portion 71.

上述したように、収容部７１は、一部又は全部がタンク１１の洗浄液中に浸かっている。従って、排出路８５の他端８５１から汚液が収容部７１に流入する際、汚液の勢いを抑えることができ、収容部７１内の沈殿物が舞い上がることを防止できる。従って、収容部７１内の沈殿物が舞い上がることにより、タンク１１内の洗浄液が汚れる等の弊害を防止できる。   As described above, the container 71 is partially or entirely immersed in the cleaning liquid of the tank 11. Therefore, when the waste liquid flows into the storage part 71 from the other end 851 of the discharge path 85, the momentum of the waste liquid can be suppressed, and the precipitate in the storage part 71 can be prevented from rising. Therefore, it is possible to prevent an adverse effect such as the cleaning liquid in the tank 11 becoming dirty when the precipitate in the storage portion 71 soars.

FIG. 3 is a schematic view showing the waste liquid receiving apparatus 70 according to the second embodiment. FIG. 3A is a schematic perspective view of the waste fluid receiving device 70, and FIG. 3B is a view of the waste fluid receiving device 70 as viewed from the white arrow direction of FIG. 3A.

汚液受取装置７０は排出路８５から流れ込む汚液を収容する収容部７１と、案内部７４を備えている。案内部７４は、第１フィルタ６２からの汚液を収容部７１に案内する。収容部７１は切粉より小さい孔を有する網筒体である。例えば収容部７１は円筒形状をなしており、上部の一面が開放口７２であり、下部に底面７３を有している。収容部７１は、少なくとも下部がタンク１１の洗浄液中に浸かっている。望ましくは、収容部７１の全体がタンク１１の洗浄液中に浸かっていれば良い。   The liquid receiving apparatus 70 includes a container 71 for containing the liquid flowing from the discharge passage 85 and a guiding part 74. The guiding unit 74 guides the dirty fluid from the first filter 62 to the storage unit 71. The housing portion 71 is a mesh cylinder having a hole smaller than the chips. For example, the housing portion 71 has a cylindrical shape, one surface of the upper portion is an opening 72, and the lower surface has a bottom surface 73. At least the lower portion of the housing portion 71 is immersed in the cleaning liquid of the tank 11. Desirably, the entire storage unit 71 may be immersed in the cleaning liquid of the tank 11.

案内部７４は、収容部７１と同一径を有する円筒形状であり、上下の面を開放している。案内部７４は収容部７１の上方に位置し、案内部７４と収容部７１は同軸上に位置している。案内部７４の下端縁は、収容部７１の開放口７２に連設している。案内部７４は、内外を貫通する貫通孔７５を設けており、貫通孔７５に排出路８５の他端８５１が接続している。   The guide part 74 is a cylindrical shape which has the same diameter as the accommodating part 71, and opens the upper and lower surfaces. The guiding portion 74 is located above the housing portion 71, and the guiding portion 74 and the housing portion 71 are coaxially located. The lower end edge of the guide portion 74 is continuous with the opening 72 of the housing portion 71. The guide portion 74 is provided with a through hole 75 penetrating inside and outside, and the other end 851 of the discharge path 85 is connected to the through hole 75.

第１フィルタ６２が吐出した汚液は、排出路８５の他端８５１から案内部７４内に流れ込み、案内部７４は汚液を収容部７１に案内する。図３Ｂにおける矢印は案内部７４内における汚液の流れを示す。汚液は案内部７４の内側面に沿って案内部７４の周方向に流れ初め、徐々に収容部７１に流れる。従って、排出路８５の他端８５１から汚液が勢い強く収容部７１内の沈殿物に落ちることを未然に防ぎ、収容部７１内の沈殿物が舞い上がることを防止できる。   The dirty fluid discharged by the first filter 62 flows into the guide 74 from the other end 851 of the discharge path 85, and the guide 74 guides the dirty fluid to the storage 71. Arrows in FIG. 3B indicate the flow of dirty fluid in the guide portion 74. The filth liquid begins to flow in the circumferential direction of the guide portion 74 along the inner side surface of the guide portion 74 and gradually flows to the containing portion 71. Therefore, it is possible to prevent the waste liquid from falling strongly to the precipitate in the storage unit 71 from the other end 851 of the discharge path 85 and to prevent the precipitate in the storage unit 71 from rising.

汚液は案内部７４の内側面に沿って流れ込んで収容部７１の底面７３上に沈殿し、汚液が含む洗浄液は収容部７１の網を介してタンク１１内に流れる。従って、汚液中の洗浄液を回収できる。汚液から回収した洗浄液はタンク１１に溜まり、第１ポンプ６１が再び工具の洗浄・冷却に供給する。従って、収容部７１に溜まった汚液を廃棄するメンテナンスの手間を軽減できる。   The filth liquid flows along the inner side surface of the guide portion 74 and precipitates on the bottom surface 73 of the housing portion 71, and the cleaning solution contained in the filth liquid flows into the tank 11 through the mesh of the housing portion 71. Therefore, the cleaning liquid in the contaminated fluid can be recovered. The cleaning liquid collected from the dirty liquid is collected in the tank 11, and the first pump 61 supplies the cleaning and cooling of the tool again. Therefore, it is possible to reduce the time and effort of maintenance for disposing of the contaminated fluid accumulated in the accommodating portion 71.

上述したように、収容部７１は、一部又は全部がタンク１１の洗浄液中に浸かっている。従って、排出路８５の他端８５１から汚液が収容部７１に流入する際、汚液の勢いを抑えることができ、収容部７１内の沈殿物が舞い上がることを防止できる。   As described above, the container 71 is partially or entirely immersed in the cleaning liquid of the tank 11. Therefore, when the waste liquid flows into the storage part 71 from the other end 851 of the discharge path 85, the momentum of the waste liquid can be suppressed, and the precipitate in the storage part 71 can be prevented from rising.

図４は実施の形態３に係る汚液受取装置７０を表す模式図である。汚液受取装置７０は排出路８５から流れ込む汚液を収容する収容部７１と、案内部７４Ａを備えている。案内部７４Ａは、第１フィルタ６２からの汚液を収容部７１に案内する。 Third Embodiment
FIG. 4 is a schematic view showing the waste liquid receiving apparatus 70 according to the third embodiment. The liquid receiving apparatus 70 includes a container 71 for containing the liquid flowing from the discharge passage 85, and a guiding part 74A. The guide portion 74A guides the dirty fluid from the first filter 62 to the storage portion 71.

案内部７４Ａは板形状をなしており、収容部７１の上部の内側に位置している。案内部７４Ａは収容部７１の底面７３に対して傾けている。第１フィルタ６２からの汚液は、排出路８５の他端８５１から案内部７４Ａ内に向けて流れ落ちる。案内部７４は斯かる汚液をその上面７４１に沿って下方（収容部７１）に流すことにより、収容部７１に案内する。図４における矢印は案内部７４Ａの案内による汚液の流れを示す。従って、排出路８５の他端８５１から汚液が勢い強く収容部７１内に落ちることを未然に防ぎ、収容部７１内の沈殿物が舞い上がることを防止できる。   The guide portion 74A has a plate shape and is located inside the upper portion of the housing portion 71. The guide portion 74A is inclined with respect to the bottom surface 73 of the housing portion 71. The dirty fluid from the first filter 62 flows down from the other end 851 of the discharge passage 85 into the guide portion 74A. The guiding portion 74 guides the waste liquid to the containing portion 71 by flowing the dirty liquid downward (the containing portion 71) along the upper surface 741. The arrows in FIG. 4 indicate the flow of the dirty liquid by the guidance of the guiding portion 74A. Therefore, it is possible to prevent the waste liquid from falling vigorously into the storage portion 71 from the other end 851 of the discharge path 85 and to prevent the precipitate in the storage portion 71 from rising.

収容部７１は切粉より小さい孔を有する網筒体である。例えば収容部７１は円筒形状をなしており、開放口７２と底面７３を有している。収容部７１は、少なくとも下部がタンク１１の洗浄液中に浸かっている。望ましくは、収容部７１の全体がタンク１１の洗浄液中に浸かっていれば良い。   The housing portion 71 is a mesh cylinder having a hole smaller than the chips. For example, the housing portion 71 has a cylindrical shape, and has an opening 72 and a bottom surface 73. At least the lower portion of the housing portion 71 is immersed in the cleaning liquid of the tank 11. Desirably, the entire storage unit 71 may be immersed in the cleaning liquid of the tank 11.

第１フィルタ６２が吐出した汚液は、排出路８５を介して汚液受取装置７０に流入する。排出路８５の他端８５１は収容部７１の開放口７２の付近であって、案内部７４Ａの上方にて開口している。第１フィルタ６２からの汚液は排出路８５の他端８５１から案内部７４Ａの上面７４１上を流れて収容部７１内に貯まる。汚液は収容部７１の底面７３上に沈殿し、汚液が含む洗浄液は収容部７１の網を介してタンク１１内に流れる。従って、汚液中の洗浄液を回収できる。回収した洗浄液はタンク１１に溜まり、第１ポンプ６１が再び工具の洗浄・冷却に供給する。従って、収容部７１に溜まった汚液を廃棄するメンテナンスの手間を軽減できる。   The waste fluid discharged by the first filter 62 flows into the waste fluid receiving device 70 through the discharge passage 85. The other end 851 of the discharge path 85 is in the vicinity of the opening 72 of the housing portion 71 and opens above the guide portion 74A. The dirty fluid from the first filter 62 flows from the other end 851 of the discharge path 85 onto the upper surface 741 of the guide portion 74A and is stored in the storage portion 71. The contaminated solution is deposited on the bottom surface 73 of the storage unit 71, and the cleaning solution contained in the contaminated solution flows into the tank 11 through the mesh of the storage unit 71. Therefore, the cleaning liquid in the contaminated fluid can be recovered. The collected cleaning solution is accumulated in the tank 11, and the first pump 61 supplies the cleaning and cooling of the tool again. Therefore, it is possible to reduce the time and effort of maintenance for disposing of the contaminated fluid accumulated in the accommodating portion 71.

上述したように、収容部７１は、一部又は全部がタンク１１の洗浄液中に浸かっている。従って、排出路８５の他端８５１から汚液が収容部７１に流入する際、汚液の勢いを抑えることができ、収容部７１内の沈殿物が舞い上がることを防止できる。   As described above, the container 71 is partially or entirely immersed in the cleaning liquid of the tank 11. Therefore, when the waste liquid flows into the storage part 71 from the other end 851 of the discharge path 85, the momentum of the waste liquid can be suppressed, and the precipitate in the storage part 71 can be prevented from rising.

FIG. 5 is a schematic view showing the waste liquid receiving apparatus 70 according to the fourth embodiment. FIG. 5A is a schematic perspective view of the waste fluid receiving device 70, and FIG. 5B is a view of the waste fluid receiving device 70 as viewed in the direction of the white arrow in FIG. 5A. In FIG. 5B, the discharge path 85 is indicated by an alternate long and short dash line for convenience.

汚液受取装置７０は排出路８５から流れ込む汚液を収容する収容部７１と、案内部７４Ｂを備えている。案内部７４Ｂは、第１フィルタ６２からの汚液を収容部７１に案内する。収容部７１は切粉より小さい孔を有する網筒体である。収容部７１は開放口７２と底面７３を有している。収容部７１は、少なくとも下部がタンク１１の洗浄液中に浸かっている。望ましくは、収容部７１の全体がタンク１１の洗浄液中に浸かっていれば良い。   The liquid receiving apparatus 70 includes a container 71 for containing the liquid flowing from the discharge passage 85, and a guiding part 74B. The guide portion 74B guides the dirty fluid from the first filter 62 to the storage portion 71. The housing portion 71 is a mesh cylinder having a hole smaller than the chips. The housing portion 71 has an opening 72 and a bottom surface 73. At least the lower portion of the housing portion 71 is immersed in the cleaning liquid of the tank 11. Desirably, the entire storage unit 71 may be immersed in the cleaning liquid of the tank 11.

案内部７４Ｂは、下端縁が収容部７１と同一径を有し、上方から下方に向けて径が拡大する円筒形状である。すなわち、案内部７４Ｂは漏斗形状であり、上下の面を開放している。案内部７４Ｂは収容部７１の上方に位置し、案内部７４Ｂと収容部７１は同軸上に位置している。案内部７４Ｂの下端縁は、収容部７１の開放口７２に連設している。案内部７４Ｂは内外を貫通する貫通孔７５を中上部に設けており、貫通孔７５に排出路８５の他端８５１が接続している。   The guide portion 74B has a cylindrical shape whose lower end edge has the same diameter as the accommodation portion 71 and whose diameter increases from the upper side to the lower side. That is, the guide portion 74B has a funnel shape and opens the upper and lower surfaces. The guiding portion 74B is located above the housing portion 71, and the guiding portion 74B and the housing portion 71 are coaxially located. The lower end edge of the guide portion 74 </ b> B is continuous with the opening 72 of the housing portion 71. The guide portion 74 </ b> B is provided with a through hole 75 passing through the inside and the outside at the middle upper portion, and the other end 851 of the discharge path 85 is connected to the through hole 75.

第１フィルタ６２が吐出した汚液は、排出路８５の他端８５１から案内部７４Ｂ内に流れ込み、案内部７４Ｂは汚液を収容部７１に案内する。図５Ｂにおける矢印は案内部７４Ｂ内における汚液の流れを示す。汚液は案内部７４Ｂの内側面に沿って案内部７４Ｂの周方向に流れ初め、図５Ｂに示すように渦巻き状に収容部７１方に流れる。従って、排出路８５の他端８５１から汚液が勢い強く収容部７１内に落ちることを未然に防ぎ、収容部７１内の沈殿物が舞い上がることを防止できる。   The dirty fluid discharged by the first filter 62 flows into the guide part 74B from the other end 851 of the discharge path 85, and the guide part 74B guides the dirty liquid to the storage part 71. Arrows in FIG. 5B indicate the flow of the dirty fluid in the guide portion 74B. The filth liquid begins to flow in the circumferential direction of the guiding portion 74B along the inner side surface of the guiding portion 74B, and flows toward the containing portion 71 in a spiral as shown in FIG. 5B. Therefore, it is possible to prevent the waste liquid from falling vigorously into the storage portion 71 from the other end 851 of the discharge path 85 and to prevent the precipitate in the storage portion 71 from rising.

汚液は案内部７４Ｂの内側面に沿って流れ込んで収容部７１の底面７３上に沈殿し、汚液が含む洗浄液は収容部７１の網を介してタンク１１内に流れる。従って、汚液中の洗浄液を回収できる。汚液から回収した洗浄液はタンク１１に溜まり、第１ポンプ６１が再び工具の洗浄・冷却に供給する。従って、収容部７１に溜まった汚液を廃棄するメンテナンスの手間を軽減できる。   The dirty fluid flows along the inner side surface of the guiding part 74 B and precipitates on the bottom surface 73 of the containing part 71, and the cleaning solution contained in the dirty fluid flows into the tank 11 through the net of the containing part 71. Therefore, the cleaning liquid in the contaminated fluid can be recovered. The cleaning liquid collected from the dirty liquid is collected in the tank 11, and the first pump 61 supplies the cleaning and cooling of the tool again. Therefore, it is possible to reduce the time and effort of maintenance for disposing of the contaminated fluid accumulated in the accommodating portion 71.

収容部７１は、一部又は全部がタンク１１の洗浄液中に浸かっているので、排出路８５の他端８５１から汚液が収容部７１に流入する際、収容部７１内の沈殿物が舞い上がることを防止できる。   Since the storage portion 71 is partially or entirely immersed in the cleaning liquid in the tank 11, the sediment in the storage portion 71 soars when the dirty fluid flows into the storage portion 71 from the other end 851 of the discharge path 85 Can be prevented.

以上においては、収容部７１が円筒形状である場合を例に挙げて説明したが、これに限るものでない。例えば、四角筒形状であっても良く、三角筒形状であっても良い。この際、案内部７４，７４Ｂは、収容部７１と同形状にすれば良い。   In the above, although the case where the accommodating part 71 was cylindrical shape was mentioned as the example and demonstrated, it does not restrict to this. For example, it may be in the form of a square cylinder or in the form of a triangular cylinder. At this time, the guide portions 74 and 74B may have the same shape as the housing portion 71.

図６は実施の形態５に係る汚液受取装置７０を表す模式図である。 Fifth Embodiment
FIG. 6 is a schematic view showing the waste liquid receiving apparatus 70 according to the fifth embodiment.

汚液受取装置７０は排出路８５から流れ込む汚液を収容する収容部７１と、案内部７４Ｃを備えている。案内部７４Ｃは、第１フィルタ６２からの汚液を収容部７１に案内する。収容部７１は切粉より小さい孔を有する網筒体である。例えば収容部７１は四角筒形状をなしている。収容部７１は上部の一面を開放しており、下部に底面７３を有している。収容部７１は、少なくとも下部がタンク１１の洗浄液中に浸かっている。望ましくは、収容部７１の全体がタンク１１の洗浄液中に浸かっていれば良い。   The liquid receiving apparatus 70 includes a container 71 for containing the liquid flowing from the discharge passage 85, and a guiding part 74C. The guide portion 74C guides the dirty fluid from the first filter 62 to the storage portion 71. The housing portion 71 is a mesh cylinder having a hole smaller than the chips. For example, the housing portion 71 is in the form of a square tube. The housing portion 71 is open at one side at the top, and has a bottom surface 73 at the bottom. At least the lower portion of the housing portion 71 is immersed in the cleaning liquid of the tank 11. Desirably, the entire storage unit 71 may be immersed in the cleaning liquid of the tank 11.

汚液受取装置７０は蓋７７を備えている。蓋７７は矩形の板形状をなしており、収容部７１の上方の一面を覆っている。蓋７７は厚み方向に貫通する矩形の流入開口７７１を有している。蓋７７の上方には排出路８５の他端８５１が位置しており、流入開口７７１を介して汚液が収容部７１内に流れ込む。流入開口７７１の下方には案内部７４Ｃが位置している。尚、排出路８５の他端８５１と蓋７７が接続し、流入開口７７１は排出路８５（他端８５１）の水平断面と同形状に形成し、排出路８５の他端８５１と流入開口７７１の間の隙間を塞ぐように形成するのが望ましい。   The liquid receiving device 70 is provided with a lid 77. The lid 77 has a rectangular plate shape and covers one surface above the housing portion 71. The lid 77 has a rectangular inflow opening 771 penetrating in the thickness direction. The other end 851 of the discharge path 85 is located above the lid 77, and the dirty fluid flows into the accommodation portion 71 through the inflow opening 771. The guide portion 74C is located below the inflow opening 771. The other end 851 of the discharge path 85 and the lid 77 are connected, the inflow opening 771 is formed in the same shape as the horizontal cross section of the discharge path 85 (the other end 851), and the other end 851 of the discharge path 85 and the inflow opening 771 It is desirable to form so as to close the gap between them.

案内部７４Ｃは対向する２つの開口端７４４，７４４を有する樋形状を有している。案内部７４Ｃは蓋７７と略平行である矩形の扁平板部７４１を有する。扁平板部７４１は流入開口７７１に対応する大きさを有する。案内部７４Ｃは扁平板部７４１の対向する２つの辺から扁平板部７４１に交差する方向の上向きに延びる一対の対向板部７４２，７４２を有している。対向板部７４２，７４２は内側面が相互対向している。対向板部７４２，７４２の下部縁は扁平板部７４１に連設しており、対向板部７４２，７４２の上部縁は流入開口７７１に連設している。   The guide portion 74C has a wedge shape having two opposite open ends 744 and 744. The guide portion 74C has a rectangular flat plate portion 741 substantially parallel to the lid 77. The flat plate portion 741 has a size corresponding to the inflow opening 771. The guide portion 74C has a pair of opposing plate portions 742 and 742 extending upward from the two opposing sides of the flat plate portion 741 in the direction intersecting the flat plate portion 741. The opposing plate portions 742 and 742 have their inner side surfaces facing each other. The lower edges of the opposing plates 742 and 742 are connected to the flat plate 741, and the upper edges of the opposing plates 742 and 742 are connected to the inflow opening 771.

第１フィルタ６２が吐出した汚液は、排出路８５の他端８５１から流入開口７７１を介して案内部７４Ｃ内に流れ込み、案内部７４Ｃは汚液を収容部７１に案内する。図６における矢印は案内部７４Ｃの案内による汚液の流れを示す。汚液は案内部７４Ｃの扁平板部７４１に当たって扁平板部７４１に沿って流れ、開口端７４４，７４４を介して案内部７４Ｃの外側に流れ出る。従って、排出路８５の他端８５１からの汚液の落下距離を減らす。これにより、汚液が勢い強く収容部７１内に落ちることを未然に防ぎ、収容部７１内の沈殿物が舞い上がることを防止できる。   The dirty fluid discharged by the first filter 62 flows into the guide portion 74C from the other end 851 of the discharge path 85 through the inflow opening 771, and the guide portion 74C guides the dirty fluid to the storage portion 71. The arrows in FIG. 6 indicate the flow of the dirty liquid by the guidance of the guiding portion 74C. The waste liquid strikes the flat plate portion 741 of the guide portion 74C and flows along the flat plate portion 741 and flows out to the outside of the guide portion 74C through the open ends 744 and 744. Therefore, the falling distance of the waste fluid from the other end 851 of the discharge path 85 is reduced. As a result, it is possible to prevent the septic fluid from falling into the container 71 vigorously and prevent the precipitate in the container 71 from rising.

汚液は案内部７４Ｃを介して流れ込んで収容部７１の底面７３上に沈殿し、汚液が含む洗浄液は収容部７１の網を介してタンク１１内に流れる。従って、汚液中の洗浄液を回収できる。汚液から回収した洗浄液はタンク１１に溜まり、第１ポンプ６１が再び工具の洗浄・冷却に供給する。従って、収容部７１に溜まった汚液を廃棄するメンテナンスの手間を軽減できる。   The dirty fluid flows into the tank 11 through the guiding part 74C and precipitates on the bottom surface 73 of the container 71, and the cleaning solution contained in the dirty fluid flows into the tank 11 through the mesh of the container 71. Therefore, the cleaning liquid in the contaminated fluid can be recovered. The cleaning liquid collected from the dirty liquid is collected in the tank 11, and the first pump 61 supplies the cleaning and cooling of the tool again. Therefore, it is possible to reduce the time and effort of maintenance for disposing of the contaminated fluid accumulated in the accommodating portion 71.

収容部７１は、一部又は全部がタンク１１の洗浄液中に浸かっているので、排出路８５の他端８５１から汚液が収容部７１に流入する際、収容部７１内の沈殿物が舞い上がることを防止できる。   Since the storage portion 71 is partially or entirely immersed in the cleaning liquid in the tank 11, the sediment in the storage portion 71 soars when the dirty fluid flows into the storage portion 71 from the other end 851 of the discharge path 85. Can be prevented.

収容部７１は案内部７４Ｃの対向板部７４２，７４２の外側面と斜めに対向する位置に流通開口７６を夫々有している。収容部７１内の沈殿物は流通開口７６，７６を介して収容部７１の外側に流れ出すことが可能である。例えば、収容部７１に沈殿物が過剰沈殿している場合、沈殿物は流通開口７６，７６を介して収容部７１の外側にオーバーフローする。従って、過剰沈殿によって沈殿物が流入開口７７１を介して蓋７７上に盛り上がることにより、作業場が汚れる等の弊害を防止できる。   The housing portion 71 has a flow opening 76 at a position obliquely facing the outer side surfaces of the opposing plate portions 742 and 742 of the guide portion 74C. The precipitate in the storage portion 71 can flow out of the storage portion 71 through the flow openings 76, 76. For example, when the precipitate is excessively precipitated in the accommodating portion 71, the precipitate overflows to the outside of the accommodating portion 71 through the flow openings 76 and 76. Therefore, when the precipitate is raised on the lid 77 through the inflow opening 771 due to the excessive precipitation, it is possible to prevent an adverse effect such as soiling of the work place.
