Japanese Patent Laid-Open No. 2001-62409

一つの洗浄槽内にて洗浄と乾燥を行うようにすると、洗浄装置をコンパクトにすることができる。しかし、このようにしても、洗浄エアと乾燥エアの各ノズルが別体になっていると、エア供給部の構造及び配管が複雑となり、洗浄装置も比較的大型になるので、さらにコンパクト化することが望まれる。
また、洗浄液の表面には洗い落とされた不純物が層状をなしているため、洗浄後、洗浄液を下方の洗浄液タンクへ排水エア形式では、被洗浄物の外表面に不純物が縞状に付着してしまう。そこでこのような縞状の不純物が付着することを回避することも望まれている。本願は、このような要請の実現を目的とする。
If washing and drying are performed in one washing tank, the washing apparatus can be made compact. However, even in this case, if the nozzles for the cleaning air and the drying air are separated, the structure and piping of the air supply unit become complicated, and the cleaning device becomes relatively large. It is desirable.
In addition, since the washed-off impurities are layered on the surface of the cleaning liquid, after cleaning, the cleaning liquid is drained to the lower cleaning liquid tank. End up. Therefore, it is also desired to avoid such striped impurities from adhering. The present application aims to realize such a request.

上記課題を解決するため、洗浄装置に係る請求項１の発明は、洗浄槽と、この洗浄槽へ接続する洗浄液タンクとを備え、被洗浄物の洗浄後、洗浄槽から洗浄液タンクへ排水してから洗浄槽を共通にして被洗浄物を乾燥するようにした洗浄装置において、
洗浄槽中にノズルを設け、このノズルから洗浄液とエアを供給してキャビテーション現象により被洗浄物を洗浄するとともに、
洗浄槽から排水する際、ノズルからエアのみを噴出し、洗浄液を対流させながら排水することを特徴とする。 In order to solve the above-mentioned problems, the invention of claim 1 relating to a cleaning apparatus includes a cleaning tank and a cleaning liquid tank connected to the cleaning tank, and after washing the object to be cleaned, drains the cleaning tank from the cleaning tank to the cleaning liquid tank. In a cleaning device that uses a common cleaning tank to dry the objects to be cleaned,
A nozzle is provided in the cleaning tank, and cleaning liquid and air are supplied from this nozzle to clean the object to be cleaned by the cavitation phenomenon.
When draining from the cleaning tank, only air is ejected from the nozzle, and the drainage is performed while the cleaning liquid is convected.

請求項２の発明は上記請求項１において、排水後、ノズルから乾燥エアのみを噴出することにより、洗浄と共通のノズルを用いて被洗浄物の乾燥を行うことを特徴とする。   The invention of claim 2 is characterized in that, in the above-mentioned claim 1, after the drainage, only the dry air is ejected from the nozzle, whereby the object to be cleaned is dried using the nozzle common to the cleaning.

請求項３の発明は上記請求項１又は２において、ノズルを上下動させながら、ミックス噴流又はエアを噴出することを特徴とする。
A third aspect of the invention is characterized in that, in the first or second aspect, a mixed jet or air is ejected while moving the nozzle up and down.

請求項１の発明によれば、排水時にノズルからエアを噴出するので、洗浄槽内の洗浄液が常に対流するようになっている。このため液内の不純物は撹拌されるため、被洗浄物の外表面へ不純物が縞状に付着することを防止できる。   According to the first aspect of the present invention, air is ejected from the nozzle during drainage, so that the cleaning liquid in the cleaning tank always convects.

For this reason, since a nozzle can be used in common in each process of washing | cleaning and drying, the structure and piping of an air supply part become simple and a washing | cleaning apparatus can be made more compact.

請求項３の発明によれば、ノズルを上下動させながら、ミックス噴流又はエアを噴出するので、洗浄や乾燥を効率よくかつ均一に行うことができる。
According to invention of Claim 3, since a mixed jet or air is ejected, moving a nozzle up and down, washing | cleaning and drying can be performed efficiently and uniformly.

以下、図面に基づいて一実施例を説明する。図１は洗浄装置全体の概略図である。この洗浄装置は、洗浄槽１と、その下に配置された洗浄液タンク２とを備え、洗浄槽１内には、被洗浄物であるワーク３を支持するため支持治具４が昇降自在に設けられ、かつキャビテーション現象によりワーク３を洗浄するためのノズルユニット５も昇降自在に設けられている。   An embodiment will be described below with reference to the drawings. FIG. 1 is a schematic view of the entire cleaning apparatus. The cleaning apparatus includes a cleaning tank 1 and a cleaning liquid tank 2 disposed below the cleaning tank 1, and a support jig 4 is provided in the cleaning tank 1 so as to be movable up and down in order to support a workpiece 3 as an object to be cleaned. In addition, a nozzle unit 5 for cleaning the workpiece 3 by a cavitation phenomenon is also provided so as to be movable up and down.

この洗浄装置は、洗浄及び乾燥の各工程において、共通の洗浄槽１とノズルユニット５を使用できるようにしたものであり、洗浄液タンク２から洗浄槽１内へ洗浄液６を送水して満たし、ノズルユニット５から気泡と洗浄液が混合されたジェット流を噴射することにより洗浄し、その後、洗浄槽１内の洗浄液６を洗浄液タンク２へ排水してから、洗浄槽１内にてノズルユニット５からエアを噴出させてワーク３を乾燥するようになっている。   This cleaning apparatus is configured so that a common cleaning tank 1 and nozzle unit 5 can be used in each process of cleaning and drying. The cleaning liquid 6 is supplied from the cleaning liquid tank 2 into the cleaning tank 1 to fill the nozzle. Cleaning is performed by jetting a jet stream in which bubbles and cleaning liquid are mixed from the unit 5, and then the cleaning liquid 6 in the cleaning tank 1 is drained to the cleaning liquid tank 2, and then air is discharged from the nozzle unit 5 in the cleaning tank 1. Is ejected to dry the work 3.

洗浄槽１は、ワーク３の洗浄に十分な容量を有するものであり、その下部に切り粉受け７が設けられている。この切り粉受け７はメッシュ状のスクリーンを備え、洗浄されて洗浄槽１内を沈降する比較的大きな切り粉等の不純物を除去できるようになっている。切り粉受け７全体は引出し状に形成され、洗浄槽１の側方へ引出すことにより、切り粉等の不純物を廃棄できる。
洗浄槽１の底部近傍には、排水口（図示省略）と注水口８が設けられている。 The cleaning tank 1 has a capacity sufficient for cleaning the workpiece 3, and a chip receiver 7 is provided in the lower part thereof. The chip receiver 7 includes a mesh-like screen so that impurities such as relatively large chips that are cleaned and settle in the cleaning tank 1 can be removed. The entire chip receiver 7 is formed in a drawer shape, and by drawing it to the side of the cleaning tank 1, impurities such as chips can be discarded.
In the vicinity of the bottom of the cleaning tank 1, a drain port (not shown) and a water inlet 8 are provided.

支持治具４は、ワーク３に応じて適宜な形状及び構造のものが設けられる。本実施例では、洗浄槽１の外部に配置された上下方向の支柱４ａに対して、洗浄槽１内を昇降自在の支持部４ｂが片持ち支持されている。支持部４ｂはワーク３を支持する部分であり、上下方向の縦枠４ｃ及び底枠４ｄを備え、洗浄効率を低下させないように間隙を大きくするため、枠状もしくは網状にすることが好ましい。縦枠４ｃはワーク３及びノズルユニット５を支持する。   The support jig 4 has an appropriate shape and structure according to the workpiece 3. In the present embodiment, a support portion 4b that can move up and down in the cleaning tank 1 is cantilevered with respect to a support column 4a arranged in the vertical direction outside the cleaning tank 1. The support portion 4b is a portion that supports the workpiece 3, and includes a vertical frame 4c and a bottom frame 4d in the vertical direction. In order to increase the gap so as not to reduce the cleaning efficiency, the support portion 4b is preferably formed in a frame shape or a net shape. The vertical frame 4 c supports the work 3 and the nozzle unit 5.

洗浄液タンク２は、洗浄槽１内を満たす量の洗浄液６を収容できる容量のタンクであり、洗浄槽１よりも横長にすることによって高さ方向を低く抑制している。洗浄液タンク２の横幅方向一端側には、洗浄槽１の排水口と洗浄液タンク２の入り口９との間には、排水バルブ１０及び排水側フィルタ１１が設けられている。排水側フィルタ１１は１００μ程度のものであり、洗浄槽１から流出される排水中から切り粉受け７を通過した切り粉等の不純物を除去する。   The cleaning liquid tank 2 is a tank having a capacity capable of storing the cleaning liquid 6 in an amount that fills the cleaning tank 1, and the height direction is suppressed to be lower than that of the cleaning tank 1. A drain valve 10 and a drain side filter 11 are provided on one end side in the width direction of the cleaning liquid tank 2 between the drain port of the cleaning tank 1 and the inlet 9 of the cleaning liquid tank 2. The drain-side filter 11 is about 100 μm, and removes impurities such as chips that have passed through the chip receiver 7 from the waste water flowing out from the cleaning tank 1.

洗浄液タンク２の横幅方向他端側となる、洗浄槽１の注水口８近傍には、送水ポンプ１２から送水管１３を介して洗浄液が洗浄槽１の注水口８へ送水される。送水管１３の出口側には送水側フィルタ１４が設けられ、さらに送水バルブ１５を介して注水口８へ接続される。送水側フィルタ１４は５μ程度の細かいものであり、洗浄槽１内への不純物還流を極力阻止するようになっている。なお、各フィルタの目の粗さは、
切り粉受け７のスクリーン＞排水側フィルタ１１＞送水側フィルタ１４
の順になっている。 In the vicinity of the water inlet 8 of the cleaning tank 1, which is the other end in the width direction of the cleaning liquid tank 2, the cleaning liquid is supplied from the water pump 12 to the water inlet 8 of the cleaning tank 1 through the water supply pipe 13. A water supply filter 14 is provided on the outlet side of the water supply pipe 13, and is further connected to the water inlet 8 through a water supply valve 15. The water supply side filter 14 is as fine as about 5 μm, and prevents impurities from flowing back into the cleaning tank 1 as much as possible. The coarseness of each filter is
Screen of chip receiver 7> Drainage side filter 11> Water supply side filter 14
It is in order.

ノズルユニット５は複数のノズル１６を備えて上下移動自在であり、ノズル１６から噴出されるエアや洗浄液が混合されたミックス噴流又はエアを単独でワーク３の表面へ噴射するようになっている。ワーク３に対するミックス噴流等の噴射角度、すなわちノズル１３の噴出軸線がワークと傾斜するノズル角度は任意に調整できる。ノズルユニット５の上下機構は適宜可能であるが、例えば、支持治具４の上下枠４ｃを利用して上下へスライド移動可能に支持させることができる。もちろん支持治具４と別個に移動させるようにしてもよい。   The nozzle unit 5 includes a plurality of nozzles 16 and is movable up and down. The nozzle unit 5 is configured to inject a mixed jet or air mixed with air or a cleaning liquid ejected from the nozzles 16 alone onto the surface of the workpiece 3. The injection angle of the mixed jet or the like with respect to the workpiece 3, that is, the nozzle angle at which the ejection axis of the nozzle 13 is inclined with respect to the workpiece can be arbitrarily adjusted. Although the vertical mechanism of the nozzle unit 5 is possible as appropriate, it can be supported so as to be slidable up and down using the vertical frame 4c of the support jig 4, for example. Of course, it may be moved separately from the support jig 4.

図２はノズルユニット５の概略的な上面視である。ノズルユニット５は共通送水管１７に複数の枝管１８を設け、それぞれにノズル１６を接続するとともに、各ノズル１６は連結部材１９により相互に連結され、かつ連結部材１９が共通送水管１７と連結一体化されることにより全体が単一ユニットとなっている。ノズル１６の数や噴射能力等は任意に設定できる。   FIG. 2 is a schematic top view of the nozzle unit 5. In the nozzle unit 5, a plurality of branch pipes 18 are provided in the common water supply pipe 17, the nozzles 16 are connected to each of them, the nozzles 16 are connected to each other by a connection member 19, and the connection member 19 is connected to the common water supply pipe 17. By being integrated, the whole becomes a single unit. The number of nozzles 16 and the jetting capacity can be arbitrarily set.

各ノズル１６には高圧エアパイプ２０が接続され、この高圧エアパイプ２０は、ノズルユニット５の上下動等に応じて追従変形自在であり、それぞれは図示しないコンプレッサ等より高圧エアが供給され、各ノズル１６からエアを単独又はミックス噴流として噴出させるようになっている。共通送水管１７には図示しないポンプにより洗浄液が加圧供給される。   A high-pressure air pipe 20 is connected to each nozzle 16, and the high-pressure air pipe 20 can be freely deformed according to the vertical movement of the nozzle unit 5, and is supplied with high-pressure air from a compressor (not shown). The air is jetted out as a single or mixed jet. A cleaning liquid is pressurized and supplied to the common water pipe 17 by a pump (not shown).

図３は、ノズル１６部分の模式的断面を示す。ノズル１６の軸方向中間部側面には高圧エアパイプ２０が接続されるエア通路２１が突出形成され、このエア通路２１は斜めに形成されて、ノズル１６の軸方向に貫通形成されている主通路２２と斜めに合流する。   FIG. 3 shows a schematic cross section of the nozzle 16 portion. An air passage 21 to which the high pressure air pipe 20 is connected is formed on the side surface in the axial direction of the nozzle 16 so as to project, and the air passage 21 is formed obliquely so as to penetrate through the nozzle 16 in the axial direction. And joins diagonally.

ノズル１６の主通路２２へ軸方向一端側から送水された加圧水とエア通路２１からの高圧エアとがノズル１６内で混合し、気液の混合体がノズル１６の軸方向他端の噴出口２３よりミックス噴流２４となってノズル１６の軸線方向へ噴出される。このとき、多数の気泡２５が発生し、キャビテーション現象を生じさせる。   The pressurized water fed to the main passage 22 of the nozzle 16 from one end side in the axial direction and the high-pressure air from the air passage 21 are mixed in the nozzle 16, and a gas-liquid mixture is a jet outlet 23 at the other end in the axial direction of the nozzle 16. The mixed jet flow 24 is jetted in the axial direction of the nozzle 16. At this time, a large number of bubbles 25 are generated, causing a cavitation phenomenon.

洗浄液の吐出圧及び高圧エアの圧力等は、使用条件等により適宜設定され、以下に一例を示す。ただしこれらの数値はあくまで一例であり、洗浄目的等に応じて任意に設定できることは当然である。
洗浄液吐出圧 ０．９Ｍｐａ
高圧エア圧力 ０．５Ｍｐａ
ノズル角度 １５°
照射範囲（半径）２０ｍｍ
照射距離 最大２００ｍｍ The discharge pressure of the cleaning liquid, the pressure of the high-pressure air, and the like are appropriately set depending on the use conditions and the like, and examples are shown below. However, these numerical values are merely examples, and can be arbitrarily set according to the purpose of cleaning.
Cleaning liquid discharge pressure 0.9Mpa
High pressure air pressure 0.5Mpa
Nozzle angle 15 °
Irradiation range (radius) 20mm
Irradiation distance up to 200mm

次に、本実施例の作用を説明する。この洗浄装置における洗浄は、図１において、まずワーク３を支持治具４に乗せて洗浄槽１内へ入れる。このとき、洗浄槽１内へ予め送水バルブ１５を開いて洗浄液タンク２から洗浄液６供給して満たしておくか、ワーク３のセット後に供給する。洗浄液タンク２から洗浄槽１へ供給される洗浄液は、送水側フィルタ１４により不純物が可及的に除去されている。   Next, the operation of this embodiment will be described. In the cleaning in this cleaning device, in FIG. At this time, the water supply valve 15 is opened in advance into the cleaning tank 1 and the cleaning liquid 6 is supplied from the cleaning liquid tank 2 to fill it, or supplied after the work 3 is set. Impurities of the cleaning liquid supplied from the cleaning liquid tank 2 to the cleaning tank 1 are removed as much as possible by the water supply side filter 14.

次に、洗浄液６中に浸漬されたワーク３に対して、ノズルユニット５のノズル１６から高圧エアと洗浄液を混合したミックス噴流をワーク３へ噴射する。これにより、ノズル１６から噴出される高圧エアで多量の気泡が発生し、この気泡によるキャビテーション現象により、洗浄効果を大きくする。
キャビテーションの効果は一般に大気中におけるエアーブローの１０倍程度以上を期待できるものとされ、高効率でかつ小さな穴や凹部等の細部まで万遍なく洗浄できる。また、ノズルユニット５を上下動することにより、ワーク３全体を均一に洗浄できる。 Next, with respect to the work 3 immersed in the cleaning liquid 6, a mixed jet obtained by mixing high-pressure air and the cleaning liquid is sprayed from the nozzle 16 of the nozzle unit 5 to the work 3. As a result, a large amount of bubbles are generated by the high-pressure air ejected from the nozzle 16, and the cleaning effect is increased by the cavitation phenomenon caused by the bubbles.
The effect of cavitation is generally expected to be about 10 times or more that of air blow in the atmosphere, and it is highly efficient and can clean even details such as small holes and recesses. Moreover, the whole workpiece | work 3 can be wash | cleaned uniformly by moving the nozzle unit 5 up and down.

洗浄が終わると、排水バルブ１０を開いて洗浄槽１内の洗浄液６を洗浄液タンク２へ排水する。このとき、比較的大きな不純物は切り粉受け７のスクリーンにより分別される。切り粉受け７を通過した不純物は排水側フィルタ１１にて除去される。   When the cleaning is completed, the drain valve 10 is opened to drain the cleaning liquid 6 in the cleaning tank 1 into the cleaning liquid tank 2. At this time, relatively large impurities are separated by the screen of the chip receiver 7. Impurities that have passed through the chip receiver 7 are removed by the drainage filter 11.

この排水の際は、ノズルユニット５には洗浄液の供給が停止されて高圧エアのみが供給されるため、ノズル１６から高圧エアのみを噴出継続する。これにより、洗浄槽１内の洗浄液６が対流し、不純物を撹拌するため、不純物は液面へ層状に浮遊しにくくなり、不純物がワーク３の表面へ縞状に付着することを阻止し、洗浄をより確実かつ効果的にすることができる。ノズルユニット５は液面の下降に連動して下降させるか、最初から下方へ配置しておくようにすることが好ましい。   At the time of this drainage, since the supply of the cleaning liquid is stopped and only the high-pressure air is supplied to the nozzle unit 5, only the high-pressure air is continuously ejected from the nozzle 16. As a result, since the cleaning liquid 6 in the cleaning tank 1 is convected and the impurities are stirred, the impurities are less likely to float in layers on the liquid surface, and the impurities are prevented from adhering to the surface of the work 3 in a striped manner. Can be made more reliable and effective. It is preferable that the nozzle unit 5 is lowered in conjunction with the lowering of the liquid level or arranged downward from the beginning.

排水が終了すると、洗浄槽１内にはワーク３が残される。この状態でノズルユニット５には洗浄液の供給が停止されたままで乾燥エアのみが供給される。ノズル１６から乾燥エアのみをワーク３へ向かって噴出させてワーク３を乾燥する。このとき、ノズルユニット５を上下動させれば、ワーク３の乾燥を迅速かつ均一化できる。また、高圧エアを熱風にすれば、さらに効率的に乾燥できる。乾燥後、支持治具４を上昇させてワーク３を交換し、以後反復することにより、連続的に洗浄ができる。   When the drainage is completed, the work 3 is left in the cleaning tank 1. In this state, only the dry air is supplied to the nozzle unit 5 while the supply of the cleaning liquid is stopped. Only the dry air is ejected from the nozzle 16 toward the work 3 to dry the work 3. At this time, if the nozzle unit 5 is moved up and down, the workpiece 3 can be dried quickly and uniformly. Moreover, if high pressure air is used as hot air, it can dry more efficiently. After drying, the support jig 4 is raised, the workpiece 3 is replaced, and the process is repeated thereafter, whereby continuous cleaning can be performed.

このように、洗浄工程と乾燥工程において、洗浄槽１とノズルユニット５を共通化できるので、従来のように、ワーク脱着、洗浄、乾燥等の各工程を分離し、工程間にワーク３を移送しながら作業する必要がないので、洗浄作業及び設備を簡単化できる。また、ノズルユニット５を上下動させながら、ミックス噴流又はエアを噴出することにより、洗浄や乾燥を効率よくかつ均一に行うことができる。   As described above, since the cleaning tank 1 and the nozzle unit 5 can be used in common in the cleaning process and the drying process, each process such as workpiece removal, cleaning, and drying is separated as in the prior art, and the workpiece 3 is transferred between processes. However, since it is not necessary to work, cleaning work and equipment can be simplified. Moreover, washing and drying can be performed efficiently and uniformly by ejecting the mixed jet or air while moving the nozzle unit 5 up and down.

しかも、洗浄と乾燥におけるノズルユニット５を共通化することにより、ノズルユニット５の配置を単一にでき、配管も一つのノズルユニット５に対するものだけで足りるので、キャビテーション効果と乾燥に必要なノズルユニット５等におけるエア供給部の配置及び配管を簡単にでき、かつ小型化できる。
そのうえ、洗浄槽１と洗浄液タンク２を上下に重ねただけの構造であるから、洗浄装置全体を、構造簡単かつコンパクト化できる。
In addition, by sharing the nozzle unit 5 for cleaning and drying, the nozzle unit 5 can be arranged in a single unit, and only one nozzle unit 5 is required for piping, so the nozzle unit necessary for cavitation effect and drying. The arrangement and piping of the air supply unit in 5 etc. can be simplified and downsized.
In addition, since the cleaning tank 1 and the cleaning liquid tank 2 are simply stacked one above the other, the entire cleaning device can be simplified and made compact.
