Description
この発明は、マシニングセンタや旋盤等の工作機械に用いられる切削液タンクに関する。 The present invention relates to a cutting fluid tank used in machine tools such as machining centers and lathes.
例えばマシニングセンタや旋盤のような切削加工を行う工作機械では、工具の潤滑および冷却ならびにスラッジの排出を目的として、切削液（クーラント）が一般的に用いられている。
切削液供給ポンプにより、ワークの切削加工が行われる工作機械の加工室（加工部）に向けて吐出された切削液は、ワークから削り取られた切粉などのスラッジとともに加工部から排出される。排出された切削液は、これに混入したスラッジのうち比較的大きなものがチップコンベアやフィルタによって分離除去された後、切削液タンクのタンク本体に流入して一時的に貯留され、ここから切削液供給ポンプにより再び加工部へ供給される。
ここで、チップコンベアやフィルタによって分離除去することができなかった比較的小さいスラッジは、切削液とともにタンク本体内に流入するが、スラッジが混入したままの切削液が切削液供給ポンプなどの機器に吸い込まれると、機器の損傷や故障を引き起こすだけでなく、スラッジが混入したままの切削液が加工部に供給されると加工不良が生じるおそれがあった。
また、切削液に混入したスラッジがタンク本体の底に堆積することにより、タンク本体の有効容積、すなわち切削液自体を貯留するための容積が低減するおそれ、また、切削液が腐敗して作業環境が損なわれるおそれがあった。
さらにスラッジは、沈殿してタンク本体の底部に堆積するため、一見しただけでは堆積の状態や量を把握するのが難しいうえ、堆積したスラッジを取り除く作業も多大な時間と労力を要するものであった。
For example, in machine tools that perform cutting, such as machining centers and lathes, cutting fluid (coolant) is generally used for the purposes of lubricating and cooling tools and discharging sludge.
The cutting fluid is discharged by a cutting fluid supply pump toward a processing chamber (processing section) of a machine tool where a workpiece is cut, and is discharged from the processing section along with sludge such as chips scraped from the workpiece. The relatively large sludge mixed in the discharged cutting fluid is separated and removed by a chip conveyor and filter, and then flows into the tank body of the cutting fluid tank where it is temporarily stored, from which the cutting fluid is extracted. It is again supplied to the processing section by the supply pump.
Here, the relatively small sludge that could not be separated and removed by the chip conveyor or filter flows into the tank body together with the cutting fluid, but the cutting fluid with the sludge mixed in is sent to equipment such as the cutting fluid supply pump. If the sludge is sucked in, it may not only cause damage or malfunction of the equipment, but also cause machining defects if the cutting fluid containing sludge is supplied to the machining section.
In addition, if sludge mixed into the cutting fluid accumulates at the bottom of the tank body, the effective volume of the tank body, that is, the volume for storing the cutting fluid itself, may decrease, and the cutting fluid may rot and cause the work environment to deteriorate. could be damaged.
Furthermore, since sludge settles and accumulates at the bottom of the tank body, it is difficult to grasp the state and amount of accumulation at first glance, and the work of removing accumulated sludge requires a great deal of time and effort. Ta.
そこで、例えば下記特許文献１、２に記載の通り、切削液タンクのタンク本体内に切削液を撹拌するスクリューを設置して、スラッジがタンク本体の底部に堆積するのを防止する切削液タンクが知られている。
Therefore, for example, as described in
しかしながら、上記特許文献１、２の切削液タンクのようにタンク本体内にスクリューを設置する場合、その効果はタンク本体内の一定範囲に限られタンク本体内の広い範囲にスラッジが堆積するのを効果的に防止することができなかった。また、モータの駆動や、スクリューの回転による切削液温度の上昇や消費電力の増加といった問題もあった。
However, when installing a screw inside the tank body as in the cutting fluid tanks of
この発明の目的は、上記の課題に鑑みてなされたものであって、切削液温度の上昇や消費電力の増加を抑制しながら、タンク本体内の広い範囲においてスラッジが堆積するのをより効果的に防止できる切削液タンクを提供することにある。 The purpose of this invention was made in view of the above-mentioned problems, and it is an object of the present invention to more effectively prevent sludge from accumulating in a wide range within the tank body while suppressing increases in cutting fluid temperature and power consumption.

上記１）の切削液タンクによれば、タンク本体内の切削液流路を流れるスラッジ含有切削液を汲み上げて一旦切削液流路外へ取り出して、スラッジを除去し、清浄化された切削液を再び切削液流路に戻すことで、切削液流路を流れる切削液に含有されるスラッジの量が低減され、タンク本体内の広い範囲においてスラッジが堆積するのを効果的に防止できるうえに、加工部へ供給される切削液に含有されるスラッジの量も低減される。さらに、タンク本体にモータやスクリューを設置する必要がないため、切削液温度の上昇や消費電力の増加を効果的に抑制することができる。 According to the cutting fluid tank described in 1) above, the sludge-containing cutting fluid flowing through the cutting fluid flow path in the tank body is pumped up and taken out of the cutting fluid flow path, the sludge is removed, and the cleaned cutting fluid is released. By returning the cutting fluid to the cutting fluid flow path, the amount of sludge contained in the cutting fluid flowing through the cutting fluid flow path is reduced, and it is possible to effectively prevent sludge from accumulating in a wide range within the tank body. The amount of sludge contained in the cutting fluid supplied to the processing section is also reduced. Furthermore, since there is no need to install a motor or screw in the tank body, increases in cutting fluid temperature and power consumption can be effectively suppressed.
上記２）の切削液タンクによれば、切削液清浄化装置が、切削液流路からスラッジ含有切削液を汲み上げる第２汲み上げポンプと、基端が第２汲み上げポンプに接続し、先端に切削液流路の第２汲み上げポンプ下流側に位置する第１吐出部が設けられたバイパス流路と、バイパス流路上に設けられたスラッジ除去部とを有していることで、スラッジ含有切削液から確実にスラッジを除去することができ、タンク本体内にスラッジが堆積するのをより効果的に防止できる。切削液清浄化装置の上記構成に加えて、切削液供給部が第１汲み上げポンプを有していることで、切削液温度の上昇や消費電力の増加を効果的に抑制することができる。 According to the cutting fluid tank of 2) above, the cutting fluid purifying device includes a second pump pump that pumps up the sludge-containing cutting fluid from the cutting fluid flow path, a base end connected to the second pump pump, and a tip end connected to the cutting fluid tank. By having a bypass flow path with a first discharge part located downstream of the second pump, and a sludge removal part provided on the bypass flow path, it is possible to reliably remove sludge-containing cutting fluid. This allows sludge to be removed more effectively, and sludge accumulation within the tank body can be more effectively prevented.

A flow is generated, and the sludge accumulated in the flow during normal use is washed away throughout the cutting fluid flow path. Then, the washed sludge is pumped up together with the cutting fluid by the second pumping pump, and is removed by the sludge removal section in the bypass channel. This makes it possible to more effectively prevent sludge from accumulating in a wide range within the tank body.

さらに、切削液清浄化装置(4)は、バイパス流路(C1)におけるスラッジ除去部(42)の下流側の箇所から分岐し、先端に汲み上げ箇所の近傍、すなわち、第１汲み上げポンプ(70)の近傍に清浄化された切削液を吐出する第２吐出部(44)を有する逆洗用分岐流路(C2)と、清浄化された切削液の流れを前記バイパス流路(C1)または前記逆洗用分岐流路(C2)に切り替える流路切替手段（この実施形態では、分岐したバイパス流路(C1)および逆洗用分岐流路(C2)それぞれの途中に設けられた開閉弁(45)(46)）とを有している。開閉弁(45)(46)は図示しない制御装置によって制御されている。流路切替手段は、開閉弁(45)(46)に限定されず、たとえば、バイパス流路(C1)および逆洗用分岐流路(C2)の分岐点に二方向切替弁を設けてもよい。 Furthermore, the cutting fluid cleaning device (4) branches from a location downstream of the sludge removal section (42) in the bypass channel (C1), and has a tip near the pumping location, that is, a first pumping pump (70). a backwashing branch flow path (C2) having a second discharge part (44) for discharging cleaned cutting fluid near the bypass flow path (C1) or the A flow path switching means (in this embodiment, an on-off valve (45 )(46)). The on-off valves (45) and (46) are controlled by a control device (not shown). The flow path switching means is not limited to the on-off valves (45) and (46), and for example, a two-way switching valve may be provided at the branch point of the bypass flow path (C1) and the backwash branch flow path (C2). .

(P2), a third part (P3) that flows straight from the first cutting fluid discharge port (43), and a tank body (10 ) and a fourth part (P4) that bends (in this embodiment, bends at right angles) along the wall of the tank body (10) and extends from the fourth part (P4) to the corner part (PC) of the tank body (10). A fifth part (P5) that bends along (in this embodiment, bends at right angles) The sixth part (P6) bends (in this embodiment, bends at right angles) and proceeds along the wall of the tank body (10) at the corner (PC) from the sixth part (P6). In this embodiment, it consists of a seventh portion (P7) that bends at a right angle) and reaches the installation position of the first pump (70). The cutting fluid flow path (P) has a plurality of (six in the illustrated example) corner portions (PC).
工作機械の加工部から排出されたスラッジ含有切削液は切削液流入部(2)からタンク本体（10）に流入し、切削液流路(P)内を第１汲み上げポンプ(70)に向かって流れる。そして、スラッジ含有切削液は切削液流路(P)の途中に設けられた第２汲み上げポンプ(41)によって汲み上げられ、一時的にバイパス流路(C1)へ取り出される。バイパス流路(C1)へ取り出されたスラッジ含有切削液は、スラッジ除去部(42)でスラッジを除去されて清浄化される。そして、制御装置によって、開閉弁(45)は開とされ、かつ、開閉弁(46)は閉とされ、清浄化された切削液は開閉弁(45)を通ってバイパス流路(C1)を流れ、第１切削液吐出口(43)から切削液流路(P)へ吐出される。再び切削液流路(P)へ戻された清浄化された切削液は切削液流路(P)を流れ、第１汲み上げポンプ(70)によって汲み上げられて加工部へ供給される。 The sludge-containing cutting fluid discharged from the machining section of the machine tool flows into the tank body (10) from the cutting fluid inlet (2), and flows through the cutting fluid channel (P) toward the first pump pump (70). flows. Then, the sludge-containing cutting fluid is pumped up by a second pump (41) provided in the middle of the cutting fluid flow path (P) and temporarily taken out to the bypass flow path (C1). The sludge-containing cutting fluid taken out to the bypass channel (C1) is cleaned by removing sludge in the sludge removal section (42). Then, the control device opens the on-off valve (45) and closes the on-off valve (46), and the cleaned cutting fluid passes through the on-off valve (45) and enters the bypass channel (C1). The cutting fluid flows and is discharged from the first cutting fluid discharge port (43) to the cutting fluid flow path (P). The cleaned cutting fluid returned to the cutting fluid flow path (P) flows through the cutting fluid flow path (P), is pumped up by the first pump (70), and is supplied to the processing section.
切削液流入部(2)から流入したスラッジ含有切削液はバイパス流路(C1)において清浄化され、再び切削液流路(P)へ戻される。なお、第２汲み上げポンプ(41)によってスラッジ含有切削液の全量を汲み上げることができずに一部のスラッジ含有切削液がそのまま切削液流路(P)を流れてしまった場合でも、第２汲み上げポンプ(41)および第１切削液吐出口(43)間に設けられたフィルタ(8)を通過する際にスラッジが除去されるため、第１切削液吐出口(43)から吐出される清浄化された切削液にスラッジが混入することはない。 The sludge-containing cutting fluid that has flowed in from the cutting fluid inlet (2) is cleaned in the bypass channel (C1) and returned to the cutting fluid channel (P) again. Note that even if the second pump (41) is unable to pump up the entire amount of sludge-containing cutting fluid and some of the sludge-containing cutting fluid flows through the cutting fluid flow path (P), the second pump Since sludge is removed when passing through the filter (8) provided between the pump (41) and the first cutting fluid outlet (43), the cleaning fluid discharged from the first cutting fluid outlet (43) No sludge gets mixed into the cutting fluid.
第１切削液吐出口(43)より下流側の切削液流路(P)における清浄化された切削液の流量が増加した場合、第１切削液吐出口(43)から吐出された切削液のうち一部は余剰となるが、余剰となった切削液はフィルタ(8)を通過して、再び第２汲み上げポンプ(41)で汲み上げられてバイパス流路(C1)へと取り出される。そのため、第１吐出部(43)からの切削液の吐出や第１汲み上げポンプ(70)へ向かう切削液の流れが余剰となった切削液によって妨げられることはない。 When the flow rate of the cleaned cutting fluid in the cutting fluid flow path (P) on the downstream side of the first cutting fluid outlet (43) increases, the amount of cutting fluid discharged from the first cutting fluid outlet (43) increases. A portion of the cutting fluid becomes surplus, but the surplus cutting fluid passes through the filter (8), is pumped up again by the second pumping pump (41), and is taken out to the bypass channel (C1). Therefore, the discharge of the cutting fluid from the first discharge portion (43) and the flow of the cutting fluid toward the first pumping pump (70) are not obstructed by the excess cutting fluid.
上記の通り、切削液タンクの通常使用時において、切削液は、切削液流入部(2)→切削液流路(P)→第２汲み上げポンプ(41)→バイパス流路(C1)→スラッジ除去部(42)→バイパス流路(C1)→第１切削液吐出口(43)→切削液流路(P)→第１汲み上げポンプ(70)の順で流れる。 As mentioned above, during normal use of the cutting fluid tank, the cutting fluid flows from the cutting fluid inlet (2) → cutting fluid flow path (P) → second pump pump (41) → bypass flow path (C1) → sludge removal. The fluid flows in the order of section (42) → bypass flow path (C1) → first cutting fluid discharge port (43) → cutting fluid flow path (P) → first pump pump (70).
〔逆洗時〕
次に、逆洗時の切削液の流れについて、図２の矢印を参照して説明する。なお、切削液流入部(2)から切削液流路(P)に流入したスラッジ含有切削液がスラッジ除去部(42)によって清浄化されるまでの行程は通常使用時と同様のため、省略する。
[When backwashing]
Next, the flow of cutting fluid during backwashing will be explained with reference to the arrows in FIG. 2. Note that the process until the sludge-containing cutting fluid that flows into the cutting fluid flow path (P) from the cutting fluid inflow section (2) is cleaned by the sludge removal section (42) is the same as in normal use, so it will be omitted. .
制御装置によって、開閉弁(45)は閉とされ、かつ、開閉弁(46)は開とされる。スラッジ除去部(42)で清浄化された切削液は開閉弁(46)を通って、逆洗用分岐流路(C2)を流れ、第２切削液吐出口(44)から切削液流路(P)の第１汲み上げポンプ(70)近傍へ吐出される。第２切削液吐出口(44)から第１汲み上げポンプ(70)近傍へ吐出された清浄化された切削液は、第１汲み上げポンプ(70)近傍に堆積したスラッジを洗い流した後、通常使用時の切削液の流れと逆方向の流れとなって切削液流路(P)を流れ、通常使用時に切削液流路(P)全体に堆積したスラッジを洗い流しながら、第２汲み上げポンプ(41)へ向かって流れる。洗い流したスラッジを含んだ切削液は、第２汲み上げポンプ(41)の手前に設けられたフィルタ(8)を通過する際にスラッジが除去された後、第２汲み上げポンプ(41)で汲み上げられてバイパス流路(C1)へと取り出される。バイパス流路(C1)へと取り出された切削液は、さらに、スラッジ除去部(42)によってスラッジが除去される。 The control device closes the on-off valve (45) and opens the on-off valve (46). The cutting fluid cleaned in the sludge removal section (42) passes through the on-off valve (46), flows through the backwashing branch channel (C2), and flows from the second cutting fluid outlet (44) to the cutting fluid channel ( P) is discharged near the first pump (70). The cleaned cutting fluid discharged from the second cutting fluid outlet (44) to the vicinity of the first pumping pump (70) washes away the sludge accumulated near the first pumping pump (70), and then, during normal use, It flows through the cutting fluid channel (P) in the opposite direction to the flow of the cutting fluid, and flows to the second pump (41) while washing away the sludge that has accumulated throughout the cutting fluid channel (P) during normal use. flowing towards. The cutting fluid containing the washed-out sludge has the sludge removed when it passes through a filter (8) provided in front of the second pump (41), and is then pumped up by the second pump (41). It is taken out to the bypass channel (C1). Sludge is further removed from the cutting fluid taken out to the bypass channel (C1) by the sludge removal section (42).
上記の通り、切削液タンクの逆洗時において、切削液は、切削液流入部(2)→切削液流路(P)→第２汲み上げポンプ(41)→バイパス流路(C1)→スラッジ除去部(42)という通常使用時と同様の流れを経た後、スラッジ除去部(42)→逆洗用分岐流路(C2)→第２切削液吐出口(44)→切削液流路(P)→フィルタ(8)→第２汲み上げポンプ(41)→バイパス流路(C1)→スラッジ除去部(42)という流れをループさせられる。 As mentioned above, when backwashing the cutting fluid tank, the cutting fluid flows through the cutting fluid inlet (2) → cutting fluid flow path (P) → second pump pump (41) → bypass flow path (C1) → sludge removal After passing through the same flow as during normal use, sludge removal section (42) → branch flow path for backwashing (C2) → second cutting fluid discharge port (44) → cutting fluid flow path (P) The flow is made into a loop: → filter (8) → second pumping pump (41) → bypass channel (C1) → sludge removal section (42).
逆洗によって、切削液流路(P)の清掃が終わると、制御装置によって開閉弁(45)が開、かつ、開閉弁(46)が閉とされ、切削液タンク(1)は再び通常使用に戻される。 Once the cutting fluid flow path (P) has been cleaned by backwashing, the control device opens the on-off valve (45) and closes the on-off valve (46), allowing the cutting fluid tank (1) to return to normal use. will be returned to.
切削液タンク(1)は、通常使用時において、タンク本体(10)内の切削液流路(P)を流れるスラッジ含有切削液を汲み上げて一旦切削液流路(P)外へ取り出して、スラッジを除去し、清浄化された切削液を再び切削液流路（P）に戻すことで、切削液流路(P)を流れる切削液に含有されるスラッジの量が低減され、タンク本体(10)内の広い範囲においてスラッジが堆積するのを効果的に防止できるうえに、加工部へ供給される切削液に含有されるスラッジの量も低減される。さらに、逆洗時において、汲み上げ箇所近傍に堆積したスラッジが洗い流されるだけでなく、通常使用時の流れと逆向きの流れによって、通常使用時に切削液流路(P)に堆積したスラッジが洗い流され、洗い流されたスラッジはフィルタ(8)およびスラッジ除去部(42)によって確実に除去される。こうして、タンク本体(10)内の広い範囲においてスラッジが堆積するのをより効果的に防止できるとともに、逆洗後の通常使用時には、加工部へ供給される切削液に含有されるスラッジの量をより確実に低減することができる。 During normal use, the cutting fluid tank (1) pumps up the sludge-containing cutting fluid flowing through the cutting fluid flow path (P) in the tank body (10), takes it out of the cutting fluid flow path (P), and removes the sludge. By removing the cleaned cutting fluid and returning the cleaned cutting fluid to the cutting fluid flow path (P), the amount of sludge contained in the cutting fluid flowing through the cutting fluid flow path (P) is reduced, and the tank body (10 ) It is possible to effectively prevent sludge from accumulating in a wide range within ), and the amount of sludge contained in the cutting fluid supplied to the processing section is also reduced. Furthermore, during backwashing, not only is the sludge that has accumulated near the pumping point washed away, but also the sludge that has accumulated in the cutting fluid flow path (P) during normal use is washed away by the flow in the opposite direction to the flow during normal use. The washed sludge is reliably removed by the filter (8) and the sludge removal section (42). In this way, it is possible to more effectively prevent sludge from accumulating in a wide area within the tank body (10), and to reduce the amount of sludge contained in the cutting fluid supplied to the machining section during normal use after backwashing. This can be reduced more reliably.
上記の実施形態によれば、切削液温度の上昇や消費電力の増加を抑制しながら、タンク本体(10)内の広い範囲においてスラッジが堆積するのをより効果的に防止できる。 According to the embodiment described above, it is possible to more effectively prevent sludge from accumulating in a wide range within the tank body (10) while suppressing increases in cutting fluid temperature and power consumption.
この発明は、例えば、工具の潤滑・冷却およびスラッジの排出を目的として切削液が用いられる工作機械に好適に用いられる。 The present invention is suitably used, for example, in machine tools in which cutting fluid is used for the purpose of lubricating and cooling tools and discharging sludge.
