Description

【0001】
【発明の属する技術分野】
本発明は、洗浄装置に関する。さらに詳述すると、本発明は、機械部品等の被洗浄物を洗浄槽、乾燥槽を経て自動洗浄する装置の構造の改良に関する。
【0002】
【従来の技術】
機械部品等のワークを加工、組立等する過程で自動洗浄するための装置として、アームで保持したワークを洗浄槽から乾燥槽へと移動させて洗浄・乾燥するようにした洗浄装置が利用されている。また、洗浄されたワークの清浄度を維持できるように、洗浄・乾燥作業エリアに清浄空気を供給してエリア内のクリーン度を保つようにした洗浄装置も利用されている。
【0003】
【発明が解決しようとする課題】
しかしながら、清浄装置における洗浄・乾燥作業エリアの全てをクリーンに保とうとすれば大型の清浄空気供給装置が必要となり装置全体の大型化を招く。また、かかる作業エリアの全てをクリーンに保つことは効率面で劣る。
【0004】
そこで、本発明は、洗浄・乾燥作業エリア中にクリーンエリアを効率良く形成することができ、小型化しやすい洗浄装置を提供することを目的とする。
【0005】
【課題を解決するための手段】
かかる目的を達成するため本件発明者は種々検討した。洗浄装置においては、洗浄槽や乾燥槽は水はね防止等のために隣り合う各槽がそれぞれ仕切られていることが一般的であるが、槽外のエリアは何ら仕切られておらず全領域がクリーンに保たれるような構造となっている。ところが、洗浄・乾燥後のワークをクリーンに保つという観点からすれば洗浄・乾燥作業エリアの全てがクリーンとされている必要はなく、少なくともある工程以降のエリアがクリーンとされていれば十分であることが知見された。
【0006】
本願発明はかかる知見に基づくものであり、請求項1記載の発明は、被洗浄物を搬入する搬入装置と、被洗浄物を洗浄する洗浄槽と、洗浄後に被洗浄物を乾燥させる乾燥槽と、被洗浄物を乾燥槽から取り出し搬出する搬出装置と、搬入装置により搬入された被洗浄物を保持して洗浄槽及び乾燥槽内に移動させる洗浄用アームとを備えてなる洗浄装置において、搬入側エリアと搬出側エリアとの間に仕切り部材を設置しこれにより仕切られた搬出側のエリア内のクリーン度を維持するようにしたことを特徴としている。
【0007】
洗浄・乾燥後の被洗浄物のクリーン度を保つ場合、洗浄前のエリアは必ずしもクリーンとされている必要はなく、少なくともある洗浄工程(あるいは乾燥工程)以降のエリアがクリーンとされていれば十分である。そこで本願発明においては、仕切り部材によって搬出側の所定のエリアを搬入側から仕切り、搬出側に局所的なクリーンエリアを形成するようにして、ある工程以降の被洗浄物をクリーンに保つようにしている。この場合、仕切り部材によって区切られたエリアのみをクリーンとすれば足りる。
【0008】
請求項2記載の発明は、請求項1記載の洗浄装置において、仕切り部材に洗浄用アームが通過可能な切り欠きを設けたことを特徴としている。例えば各槽が周状配置されたロータリー式の洗浄装置において仕切り部材により各槽をクリーンエリア側とそうでないエリア(以下、「一般環境エリア」という)側とに仕切ったような場合、各槽間で被洗浄物を移動させるための洗浄用アームは両エリア間を行き来する必要が生じるが、この洗浄装置によれば、洗浄用アームは切り欠きを通過して両エリア間を行き来することが可能である。また、クリーンエリアに供給された清浄空気はこの切り欠きを通過して一般環境エリア側に流れ込む。
【0009】
請求項3記載の発明は、請求項1または2記載の洗浄装置において、フィルタを通過した清浄空気を供給する清浄空気供給装置を搬出側のクリーンエリアの上部に設け、このクリーンエリアが搬入側エリアより正圧である状態を維持することによりクリーンエリア内のクリーン度を保持するようにしたものである。この場合、塵埃がクリーンエリア内に侵入するのを防ぎやすくなる。
【0010】
【発明の実施の形態】
以下、本発明の構成を図面に示す実施の形態の一例に基づいて詳細に説明する。
【0011】
図1〜図5に、本発明の一実施形態を示す。本発明にかかる洗浄装置10は、被洗浄物たる機械部品等(以下「ワーク」という)8を搬入する搬入装置11と、ワーク8を洗浄する洗浄槽1〜4と、洗浄後にワーク8を乾燥させる乾燥槽5〜7と、ワーク8を乾燥槽5〜7から取り出し搬出する搬出装置12と、搬入装置11により搬入されたワーク8を保持して洗浄槽1〜4及び乾燥槽5〜7内に移動させる洗浄用アーム13とを備えてなる装置である。本実施形態では、搬入装置11と搬出装置12との間に仕切り部材14を設置し、これにより仕切られた搬出側のエリア(本明細書ではこのエリアを「クリーンエリア」といい、図中において符号CAで示す)内のクリーン度を維持するようにしている。
【0012】
本実施形態の洗浄装置10は、例えば6個の槽が図1に示すように周状に等間隔配置されたロータリー式洗浄槽9を備えた装置で、その中心に配置された洗浄用アーム13がワーク8を保持して各槽1〜6へ順に搬送するように設けられている。6個の槽をいかなる槽とするかはワーク8の種別や洗浄剤として有機溶媒を用いるかどうか等により変わってくるが、例えば本実施形態の場合は1番目の槽を洗浄槽(以下「洗浄槽1」とする)、2番目から4番目までの槽をすすぎを行う洗浄槽(以下「洗浄槽2」「洗浄槽3」「洗浄槽4」とする)、5番目と6番目の槽を水切りを行うエアー乾燥槽(以下「乾燥槽5」「乾燥槽6」とする)としている。また、ロータリー槽の近傍に最終乾燥槽としての真空乾燥槽(以下「乾燥槽7」とする)を設けている。
【0013】
洗浄槽1は例えば水及び水系洗浄剤を使用した槽であり、その中に浸されたワーク8に付着した汚れを取り除いて洗浄する。水及び水系洗浄剤の代わりとして、準水系洗浄剤や非水系洗浄剤などが洗浄剤として用いられる場合もある。洗浄槽2は洗浄槽1で洗浄されたワーク8を粗すすぎする槽である。本実施形態の場合、図示するようにこれら2つの洗浄槽1,2と他の槽3〜6の間を通過するように仕切り部材14を設け、洗浄槽1,2と他の槽3〜6とを仕切っている。また洗浄槽3は2次すすぎを行う槽、洗浄槽4は3次すすぎ(最終の仕上げすすぎ)を行う槽である。乾燥槽5,6はすすぎ後のワーク8に対しエアーを吹き付けて乾燥させる槽である。さらに乾燥槽7は、槽内を真空引きしてワーク8の最終乾燥を行う槽である。
【0014】
搬入装置11は洗浄槽1の手前まで搬送されたワーク8を洗浄用アーム13に受け渡す装置で、例えば旋回可能かつ直線移動可能なアームでワーク8を保持し移動させるワーク搬入ロボットによって構成されている。本実施形態では、ワーク8をワーク搬送パレット15によってワーク搬入口16から一般環境エリア(図中では符号GAで示す)内に運び込み、搬入装置11でこのワーク8を洗浄槽1側に移動させるようにしている。本明細書では詳しくは説明しないが、ワーク搬送パレット15は搬送レール16上を自走しワーク8を搬送する台車であり、ワーク搬入口17から一般環境エリア内に入る。
【0015】
搬出装置12は乾燥を終えたワーク8を受け取り搬出側のワーク搬送パレット15に載せる装置であり、例えば搬入装置11と同様、旋回可能かつ直線移動可能なアームでワーク8を保持し移動させるワーク搬入ロボットからなる。また、ワーク搬送パレット15は搬入側の装置と同様、搬送レール16上を自走しワーク8を搬送する台車からなり、ワーク搬出口18を通過して洗浄装置10の外部にワーク8を運び出す。
【0016】
洗浄用アーム13は搬入されたワーク8を保持して洗浄槽1〜4及び乾燥槽5〜7内を順次移動させるためのアームで、本実施形態の場合は図2に示すようにクランク形状の6本の洗浄用アーム13がアーム支持軸19に周状に等間隔配置されている。アーム支持軸19は6つの槽1〜6の中心位置で回転可能かつ昇降可能な軸で、6本の洗浄用アーム13を各槽1〜6内で同時に上げ下げし、回転して次槽に移動させる。各洗浄用アーム13の先端部は、例えばワーク8を載せた状態で移動させることができるように二股形状とされ(図2参照)、あるいはワーク8の底面を支えるための保持治具が取り付けられるなどしている。本実施形態では各洗浄用アーム13を2本1組としてアーム支持軸19に取り付けることとしているが(図2参照)、各洗浄用アーム13を個別にアーム支持軸19に取り付ける構造としても構わない。
【0017】
仕切り部材14は例えば搬入装置11と搬出装置12との間に設けられた仕切り板からなり、少なくともクリーン度が保たれるべき搬出側の所定エリアを搬入側のエリア(一般環境エリア)から仕切って局所的なクリーンエリアを形成する。本実施形態の場合、洗浄槽3以降の工程をクリーン環境とするように、槽1,2側と槽3〜7側とを仕切り部材14によって仕切り、搬出側に局所的クリーンエリアを設けている(図3参照)。ただしこの仕切り方は一例であって、例えば乾燥槽4等以降をクリーンエリアとしてもよく、いずれの領域をクリーンエリアとするかによって仕切り位置を適宜変更することができる。また図3などに示すように、仕切り部材14は、アーム支持軸19を避けつつ洗浄槽2と洗浄槽3の間および洗浄槽1と乾燥槽6の間を通過するように途中で適宜折り曲げられた形状となっている。
【0018】
仕切り部材14によって仕切られたクリーンエリアの上部にはフィルタ(図示省略)を通過した清浄空気を供給する清浄空気供給装置20が設けられている(図4参照)。清浄空気供給装置20は例えばHEPA(High Efficiency Particulate Air)フィルタを通過した清浄空気をクリーンエリアに向けてダウンフローさせるファンモータユニットからなる。
【0019】
また仕切り部材14には、回転し昇降する洗浄用アーム13が通過可能な切り欠き21が設けられている。すなわち、槽1,2と槽3〜7とを仕切り部材14で仕切った本実施形態の洗浄装置1においては、洗浄槽2から洗浄槽3へと移動する洗浄用アーム13、および乾燥槽6から洗浄槽1へと戻る洗浄用アーム13が仕切り部材14を通過できるように切り欠き21を設けるようにしている。この切り欠き21の形状や大きさは特に限定されるものではないが、クリーンエリア内のクリーン度を保つ観点からすれば切り欠き面積が小さいことが好ましい。こうした場合、クリーンエリア側から一般環境エリア側への連通域が抑えられることによって流れ込む空気量を抑えられ、これによってクリーンエリア内を正圧(陽圧)に保持しやすくなることから塵埃などがクリーンエリア内に侵入するのを防ぎやすくなる。本実施形態では、図5に示すように、回転したときの洗浄用アーム13が通過可能な左右対称のクランク形状の切り欠き21aと、洗浄槽1,2内にワーク8を降下させるときの洗浄用アーム13が通過可能な縦溝形状の切り欠き21bとで切り欠き21を構成している。
【0020】
以上説明したように、本実施形態の洗浄装置10によれば、仕切り部材14が洗浄・乾燥作業エリアを一般環境エリアとクリーンエリアとに区切り、クリーンエリア内に塵埃等が入り込むのを防止する防護壁として機能する。このため、局所的なクリーンエリア内をクリーンにして洗浄・乾燥後のワーク8をクリーンに保つことができる。また、洗浄用アーム13が通過する部分のみ切り欠き21が設けられていることから、この切り欠き21を通じて排気しクリーンエリアを正圧に保持することができる。
【0021】
なお、上述の実施形態は本発明の好適な実施の一例ではあるがこれに限定されるものではなく本発明の要旨を逸脱しない範囲において種々変形実施可能である。例えば本実施形態ではロータリー式洗浄槽9を備えた洗浄装置10に仕切り部材14を設けた形態について示したがこれは一例に過ぎず、本発明の適用が可能な洗浄装置10はこのようなロータリー式洗浄装置に限らない。
【0022】
【発明の効果】
以上の説明より明らかなように、請求項1記載の洗浄装置によると、仕切り部材によって仕切られたクリーンエリア内のクリーン度を保つことによって洗浄・乾燥後のワークをクリーンのまま搬出することができる。この場合、局所的エリア内のみクリーンとすれば足り、洗浄・乾燥作業エリアの全てをクリーンに保つ必要がないのでクリーン環境を形成する際の効率を向上させることができる。また、清浄空気供給装置が大型のものでなくても済むことから装置全体の小型化を達成しやすくなる。
【0023】
請求項2記載の洗浄装置によると、仕切り部材に洗浄用アームが通過可能な切り欠きを設けたことから、この切り欠きを通過するようにして洗浄用アームを両エリア間で行き来させることが可能となる。また、クリーンエリアに供給された清浄空気をこの切り欠きを通して一般環境エリア側に排気することで、クリーンエリア内に塵埃等が入り込むのを防止することができる。
【0024】
請求項3記載の洗浄装置によると、清浄空気供給装置を搬出側クリーンエリアの上部に設け、このクリーンエリアが搬入側エリアより正圧である状態を維持することによりクリーンエリア内のクリーン度を保持することができる。この場合、塵埃がクリーンエリア内に侵入するのを防ぎやすい。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cleaning device. More specifically, the present invention relates to an improvement in the structure of an apparatus for automatically cleaning an object to be cleaned such as a mechanical part through a cleaning tank and a drying tank.
[0002]
[Prior art]
As a device for automatic cleaning in the process of processing and assembling a work such as a mechanical part, a cleaning device that moves and holds a work held by an arm from a cleaning tank to a drying tank and performs cleaning and drying is used. I have. Further, in order to maintain the cleanliness of the cleaned work, a cleaning device that supplies clean air to a cleaning / drying work area to maintain the cleanness in the area is also used.
[0003]
[Problems to be solved by the invention]
However, if all of the cleaning and drying work areas in the cleaning device are to be kept clean, a large-sized clean air supply device is required, resulting in an increase in the size of the entire device. Also, keeping all such work areas clean is inefficient.
[0004]
Therefore, an object of the present invention is to provide a cleaning device that can efficiently form a clean area in a cleaning / drying work area and that can be easily reduced in size.
[0005]
[Means for Solving the Problems]
In order to achieve such an object, the present inventors have studied variously. In cleaning equipment, the cleaning tank and drying tank are generally separated from each other in order to prevent splashing, but the area outside the tank is not partitioned at all, Is kept clean. However, from the viewpoint of keeping the work after washing and drying clean, it is not necessary that the entire washing and drying work area be clean, and it is sufficient if at least the area after a certain process is clean. It was found that
[0006]
The invention of the present application is based on such knowledge, and the invention according to claim 1 includes a carrying-in device for carrying in an object to be cleaned, a cleaning tank for cleaning the object to be cleaned, and a drying tank for drying the object to be cleaned after cleaning. , A carry-out device for taking out the object to be cleaned from the drying tank and carrying out the same, and a cleaning arm that holds the object to be cleaned carried in by the carry-in device and moves the cleaning object into the cleaning tank and the drying tank. It is characterized in that a partition member is provided between the side area and the carry-out side area, thereby maintaining the cleanliness in the partitioned-out area on the carry-out side.
[0007]
In order to maintain the cleanness of the object to be cleaned after cleaning and drying, the area before cleaning does not necessarily have to be clean, and it is sufficient if at least the area after a certain cleaning step (or drying step) is clean. It is. Therefore, in the present invention, a predetermined area on the carry-out side is partitioned from the carry-in side by the partition member, so that a local clean area is formed on the carry-out side, and the object to be cleaned after a certain process is kept clean. I have. In this case, it is sufficient that only the area partitioned by the partition member is clean.
[0008]
According to a second aspect of the present invention, in the cleaning apparatus according to the first aspect, a notch through which a cleaning arm can pass is provided in the partition member. For example, in a rotary type washing apparatus in which each tank is arranged circumferentially, when each tank is partitioned into a clean area side and a non-clean area side (hereinafter, referred to as a “general environment area”) side by a partition member, It is necessary to move the cleaning arm for moving the object to be cleaned between the two areas, but according to this cleaning device, the cleaning arm can move between the two areas through the notch. It is. The clean air supplied to the clean area passes through the notch and flows into the general environment area.
[0009]
According to a third aspect of the present invention, in the cleaning device according to the first or second aspect, a clean air supply device for supplying clean air that has passed through the filter is provided above the clean area on the carry-out side, and the clean area is a carry-in area. By maintaining a more positive pressure state, the degree of cleanness in the clean area is maintained. In this case, it is easy to prevent dust from entering the clean area.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the configuration of the present invention will be described in detail based on an example of an embodiment shown in the drawings.
[0011]
1 to 5 show one embodiment of the present invention. The cleaning device 10 according to the present invention includes a carry-in device 11 for carrying a mechanical part or the like (hereinafter, referred to as a “work”) 8 as an object to be cleaned, cleaning tanks 1 to 4 for cleaning the work 8, and drying the work 8 after the cleaning.

In the present embodiment, a partition member 14 is installed between the carry-in device 11 and the carry-out device 12, and the area on the carry-out side partitioned by this (this area is referred to as a "clean area" in the present specification; (Indicated by reference numeral CA).
[0012]
The cleaning apparatus 10 of the present embodiment is an apparatus provided with a rotary cleaning tank 9 in which six tanks are arranged at equal intervals around the circumference as shown in FIG. Are provided so as to hold the work 8 and transport it to the tanks 1 to 6 in order. The type of the six tanks depends on the type of the work 8 and whether or not an organic solvent is used as a cleaning agent. For example, in the case of the present embodiment, the first tank is a cleaning tank (hereinafter referred to as “cleaning tank”). Washing tanks for rinsing the second to fourth tanks (hereinafter referred to as “washing tank 2”, “washing tank 3” and “washing tank 4”), and the fifth and sixth tanks An air drying tank (hereinafter referred to as “drying tank 5” and “drying tank 6”) for draining water is used. In addition, a vacuum drying tank (hereinafter, referred to as “drying tank 7”) as a final drying tank is provided near the rotary tank.
[0013]
The cleaning tank 1 is a tank using, for example, water and a water-based cleaning agent, and removes dirt attached to the work 8 immersed therein to perform cleaning. A quasi-aqueous detergent or a non-aqueous detergent may be used as a detergent instead of water and an aqueous detergent. The cleaning tank 2 is a tank for roughly rinsing the work 8 cleaned in the cleaning tank 1. In the case of the present embodiment, a partition member 14 is provided so as to pass between these two cleaning tanks 1 and 2 and the other tanks 3 to 6 as shown in the figure, and the cleaning tanks 1 and 2 and the other tanks 3 to 6 are provided. And partition. The cleaning tank 3 is a tank for performing secondary rinsing, and the cleaning tank 4 is a tank for performing tertiary rinsing (final rinsing). The drying tanks 5 and 6 are tanks for drying the work 8 after rinsing by blowing air. Further, the drying tank 7 is a tank for performing final drying of the work 8 by evacuating the inside of the tank.
[0014]
The carry-in device 11 is a device that transfers the work 8 conveyed to the position just before the cleaning tank 1 to the cleaning arm 13, and is configured by, for example, a work carry-in robot that holds and moves the work 8 with a pivotable and linearly movable arm. I have. In the present embodiment, the work 8 is carried by the work transfer pallet 15 from the work carry-in entrance 16 into a general environment area (indicated by GA in the drawing), and the carry-in device 11 moves the work 8 to the cleaning tank 1 side. I have to. Although not described in detail in the present specification, the work transport pallet 15 is a carriage that travels on the transport rail 16 and transports the work 8, and enters the general environment area from the work entrance 17.
[0015]
The unloading device 12 is a device that receives the dried work 8 and places it on the work transfer pallet 15 on the unloading side. For example, similarly to the loading device 11, a work transfer that holds and moves the work 8 with a pivotable and linearly movable arm. Consists of robots. Further, the work transport pallet 15 is composed of a carriage that travels on the transport rail 16 and transports the work 8 similarly to the apparatus on the loading side, and carries the work 8 to the outside of the cleaning device 10 through the work outlet 18.
[0016]
The cleaning arm 13 is an arm for holding the loaded work 8 and sequentially moving it in the cleaning tanks 1 to 4 and the drying tanks 5 to 7. In the case of the present embodiment, as shown in FIG. Six cleaning arms 13 are circumferentially arranged on the arm support shaft 19 at equal intervals. The arm supporting shaft 19 is a rotatable and vertically movable shaft at the center position of the six tanks 1 to 6, and simultaneously raises and lowers the six cleaning arms 13 in each of the tanks 1 to 6, rotates and moves to the next tank. Let it. The distal end of each cleaning arm 13 has a forked shape (see FIG. 2) so that it can be moved with the work 8 placed thereon, or a holding jig for supporting the bottom surface of the work 8 is attached. And so on. In the present embodiment, each cleaning arm 13 is attached to the arm support shaft 19 as a set of two (see FIG. 2), but each cleaning arm 13 may be individually attached to the arm support shaft 19. .
[0017]
The partition member 14 is composed of, for example, a partition plate provided between the carry-in device 11 and the carry-out device 12, and separates a predetermined area on the carry-out side where at least cleanness is to be maintained from a carry-in side area (general environment area). Form a local clean area. In the case of the present embodiment, the tanks 1 and 2 and the tanks 3 to 7 are partitioned by the partition member 14 so that a local clean area is provided on the unloading side so that the processes after the cleaning tank 3 are set as a clean environment. (See FIG. 3). However, this partitioning method is merely an example. For example, the area after the drying tank 4 or the like may be used as a clean area, and the partition position can be appropriately changed depending on which area is used as the clean area. Further, as shown in FIG. 3 and the like, the partition member 14 is appropriately bent halfway so as to pass between the cleaning tank 2 and the cleaning tank 3 and between the cleaning tank 1 and the drying tank 6 while avoiding the arm support shaft 19. Shape.
[0018]
Above the clean area partitioned by the partition member 14, a clean air supply device 20 that supplies clean air that has passed through a filter (not shown) is provided (see FIG. 4). The clean air supply device 20 includes, for example, a fan motor unit that downflows clean air that has passed through a HEPA (High Efficiency Particulate Air) filter toward a clean area.
[0019]
Further, the partition member 14 is provided with a notch 21 through which the cleaning arm 13 that rotates and moves up and down can pass. That is, in the cleaning apparatus 1 of the present embodiment in which the tanks 1 and 2 and the tanks 3 to 7 are partitioned by the partition member 14, the cleaning arm 13 that moves from the cleaning tank 2 to the cleaning tank 3, and the drying tank 6 A notch 21 is provided so that the cleaning arm 13 returning to the cleaning tank 1 can pass through the partition member 14. The shape and size of the notch 21 are not particularly limited, but it is preferable that the notch area be small from the viewpoint of maintaining the cleanness in the clean area. In such a case, the communication area from the clean area side to the general environment area side is suppressed, so that the amount of air flowing in is suppressed, and this makes it easier to maintain the clean area at a positive pressure (positive pressure). It becomes easier to prevent intrusion into the area. In the present embodiment, as shown in FIG. 5, a symmetrical crank-shaped notch 21 a through which the cleaning arm 13 can pass when rotated, and cleaning for lowering the work 8 into the cleaning tanks 1 and 2. The notch 21 is constituted by a notch 21b having a vertical groove shape through which the arm 13 can pass.
[0020]
As described above, according to the cleaning device 10 of the present embodiment, the partition member 14 divides the cleaning / drying work area into the general environment area and the clean area, and prevents the dust and the like from entering the clean area. Functions as a wall. Therefore, the work 8 after cleaning and drying can be kept clean by cleaning the local clean area. Further, since the notch 21 is provided only in the portion where the cleaning arm 13 passes, exhaust can be performed through the notch 21 and the clean area can be maintained at a positive pressure.
[0021]
The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention. For example, in the present embodiment, the form in which the partition member 14 is provided in the cleaning apparatus 10 including the rotary cleaning tank 9 is shown, but this is merely an example, and the cleaning apparatus 10 to which the present invention can be applied is such a rotary apparatus. It is not limited to the type cleaning device.
