Description

本発明は、清浄作業空間をクリーンベンチの外部空間と仕切るため垂直方向に上下動する開閉扉上部を、前記清浄作業室内において内側に傾斜させることを可能にした気流垂直形クリーンベンチに関する。   The present invention relates to a vertical airflow clean bench that allows an upper part of an open / close door that moves up and down in a vertical direction to partition a clean work space from an external space of a clean bench, and to be inclined inward in the clean work chamber.

気流垂直形クリーンベンチは、作業台を構成する作業空間内に無塵無菌空気を供給し、該空間を清浄に保った作業空間とする。作業空間を陽圧とし、作業空間に外部汚染空気の流入を防止するために、作業空間の前面に垂直方向に上下動する開閉扉を設け作業者の手の入る範囲２０ｃｍ〜５０ｃｍの高さを扉開口範囲としている。
開閉扉は装置不使用時には作業空間の汚染を防止するために閉とするのが好ましい（特許文献１，２参照）。 The airflow vertical clean bench supplies dust-free aseptic air into the work space that constitutes the workbench to make the work space clean. In order to prevent the outside contaminated air from flowing into the work space with positive pressure in the work space, an opening / closing door that moves vertically up and down is provided on the front surface of the work space so that the operator can reach a height of 20 to 50 cm. The door opening range.
The open / close door is preferably closed to prevent contamination of the work space when the apparatus is not used (see Patent Documents 1 and 2).

然し、上記装置にあっては、作業者の目の前に開閉扉が位置するため作業者の作業に差し障りが生じることがあり、また作業者の呼気による開閉扉の曇りの発生を見ることがあった。
そこで、開閉扉の上部を作業空間側に倒し、開閉扉を傾斜させることによって、作業を容易にすると共に、作業者の呼気による開閉扉の曇りを防止するようにした装置が考えられた（特許文献３，４参照）。 However, in the above apparatus, since the opening / closing door is located in front of the operator's eyes, the operator's work may be disturbed, and the opening / closing of the opening / closing door due to the expiration of the operator may be observed. there were.
In view of this, an apparatus has been devised that makes the work easier by tilting the top and bottom of the door to the work space and tilting the door, and prevents the door from being fogged by the exhalation of the operator (patent) References 3 and 4).

図２にその一例を示すと、クリーンベンチ５１は作業空間５２を有し、その上部にファン５３，ヘパフィルター５４を有する陽圧室５５を載置し、陽圧室５５はプレフィルター５６を介して外気を取り込み作業空間５２は清浄空気を放出することを可能にしている。作業空間５２の前面には上部が陽圧室５５側に傾斜したガイド５７によって開閉扉５８が上下に摺動可能に支持されている。   As shown in FIG. 2, the clean bench 51 has a work space 52, and a positive pressure chamber 55 having a fan 53 and a hepa filter 54 is placed on the clean bench 51, and the positive pressure chamber 55 passes through a prefilter 56. Thus, the work space 52 can take in outside air and discharge clean air. An open / close door 58 is supported on the front surface of the work space 52 by a guide 57 whose upper portion is inclined toward the positive pressure chamber 55 so as to be slidable in the vertical direction.

このような構成の場合、開閉扉５８の傾斜のために作業空間５２の床面積より天井部分の面積は減少することになり作業空間への供給空気量が減少し、かつ、天井と開閉扉とが交差する付近では乱流が発生し、空気溜りが出来汚染粒子が停滞する事態も生ずる。
特開平９−１５５２０９号公報 特開２００５−２１８９２５号公報 特開２００４−１８１４３４号公報 特開２００７−１７０７６３号公報 In such a configuration, because of the inclination of the opening / closing door 58, the area of the ceiling portion is smaller than the floor area of the working space 52, the amount of air supplied to the working space is reduced, and the ceiling, the opening / closing door, In the vicinity of the crossing, turbulent flow occurs, causing a situation where air is trapped and the polluted particles stagnate.
Japanese Patent Laid-Open No. 9-155209 JP 2005-218925 A JP 2004-181434 A JP 2007-170763 A

本発明は、上記の点に鑑みて、作業者の目の前に開閉扉が位置しないようにして作業を行う上での障害をなくし、また、清浄作業空間への清浄空気を供給量を減少することなく、かつ清浄作業空間内における空気溜りの発生をなくし、作業者の呼気により開閉扉が曇る事態の発生を見ることのないクリーンベンチを得ることを目的としている。   In view of the above-mentioned points, the present invention eliminates the obstacles in performing the work so that the door is not positioned in front of the operator's eyes, and reduces the supply amount of clean air to the clean work space. An object of the present invention is to provide a clean bench that eliminates the occurrence of air pockets in the clean work space and does not see the occurrence of a situation where the opening and closing doors are clouded by the exhalation of the worker.

請求項１の発明にあっては、ファン及びヘパフィルターを有する陽圧室に連なり、前面に開閉扉を有する清浄作業空間を有するクリーンベンチにおいて、前記開閉扉は、清浄作業空間前面を垂直に上下するようガイドされ、かつ、上端が清浄作業空間内部側に倒れ込むよう軸支されたスイスルーシャッターを外枠体に設けた。
請求項２の発明にあっては、請求項１の発明において清浄作業空間内部側に倒れ込んだスイスルーシャッターの頂部と当接するガイド板を有し、該ガイド板は、スイスルーシャッターの上昇時スイスルーシャッターを起立させるものであるとした。
請求項３の発明にあっては、開閉扉は、スイスルーシャッターとスイスルーシャッターを囲んで設けた外枠体とよりなり、スイスルーシャッターは外枠体に対し揺動可能に軸支した。
請求項４記載の発明にあっては、スイスルーシャッターの側部にスイスルーシャッターと係合するガイドレールを設け、ガイドレールに設けたガイド溝とスイスルーシャッターを係合することによりスイスルーシャッターの昇降時スイスルーシャッターを開閉する。 According to the first aspect of the present invention, in the clean bench having a clean working space which is connected to a positive pressure chamber having a fan and a hepa filter and has an open / close door on the front surface, the open / close door vertically moves the front of the clean work space vertically. The Swiss frame shutter is provided on the outer frame body so that the upper end of the frame is supported and pivotally supported so that the upper end falls into the clean work space.
The invention according to claim 2 has a guide plate that contacts the top of the Swiss-Lu shutter that has fallen into the clean work space inside in accordance with the invention of Claim 1, and the guide plate is Swiss when the Swiss-Lu shutter is raised. It was supposed to raise the roux shutter.
In the invention of claim 3, the open / close door is composed of a Swiss-Lu shutter and an outer frame body provided surrounding the Swiss-Lu shutter, and the Swiss-Lu shutter is pivotally supported with respect to the outer frame body.
In the invention according to claim 4, a guide rail that engages with the Swiss-Lu shutter is provided on the side of the Swiss-Lu shutter, and the Swiss-Lu shutter is engaged by engaging the guide groove provided in the guide rail with the Swiss-Lu shutter. Open and close the Swiss Lou Shutter when lifting and lowering.

本発明は、前面に開閉扉を有し、天井部において陽圧室に連なる作業空間の前記開閉扉を、作業空間前面を垂直に上下動するよう支持すると共に、開閉扉には上端が清浄作業空間内部に倒れ込むよう軸支されたスイスルーシャッターを設けているために、清浄作業空間の床面積より天井部分の面積を減少させることがなく、即ち、傾斜した開閉扉を有するクリーンベンチに比較して清浄作業空間の天井部を狭くすることなく清浄作業空間の天井及び床面積を確保することが出来、供給する清浄作業空気量を減少させることはない。また、作業者の目の前に開閉扉が位置しない為、作業性が向上する。
天井部の陽圧室より清浄作業空間内に流出した清浄空気は室内側に倒れ込んだスイスルーシャッターにより案内された状態で外部に流出することになるから、スイスルーシャッターの両面は常に流出空気の流れの中に位置することになり作業中にシャッターが曇ることがない。 The present invention has an open / close door on the front surface, and supports the open / close door of the work space connected to the positive pressure chamber in the ceiling so that the front surface of the work space moves vertically up and down. Since the Swiss Lou shutter that is pivotally supported so as to fall into the space is provided, the area of the ceiling part is not reduced compared to the floor area of the clean work space, that is, compared with a clean bench having an inclined open / close door. Thus, the ceiling and floor area of the clean work space can be secured without narrowing the ceiling of the clean work space, and the amount of clean work air supplied is not reduced. Moreover, since the door is not located in front of the operator's eyes, workability is improved.
Clean air that has flowed into the clean working space from the positive pressure chamber on the ceiling will flow out to the outside in a state guided by the Swiss roux shutter that has fallen into the indoor side, so both sides of the Swiss roo shutter are always free of outflow air. It will be located in the flow and the shutter will not fog during work.

本発明の実施の一例を図面と共に次に説明する。図１は本発明クリーンベンチ１の縦断側面図である。クリーンベンチ１は清浄作業空間２の上部に陽圧室３を、前面に開閉扉４をそれぞれ設け、陽圧室３に取り込んだ外気を、清浄作業空間２の天井部から清浄作業空間２内に流下させ、清浄作業空間内２の前面に設けた開閉扉４を通過させ、加えて上昇している開閉扉４の下位に出来た前面開口部９からクリーンベンチ外に放出している。陽圧室２は外函５内部にファン６ヘパフィルター７を設けてなり、函外からプレフィルター８を介して外気を函内に吸引する。ヘパフィルター７を通過し清浄化された空気は、清浄作業空間２の天井部から同空間２に放出される。   An example of the implementation of the present invention will now be described with reference to the drawings. FIG. 1 is a longitudinal side view of a clean bench 1 of the present invention. The clean bench 1 is provided with a positive pressure chamber 3 in the upper part of the clean work space 2 and an open / close door 4 on the front surface, and the outside air taken into the positive pressure chamber 3 is transferred from the ceiling of the clean work space 2 into the clean work space 2. The open / close door 4 provided on the front surface of the clean working space 2 is allowed to flow down, and is further discharged out of the clean bench through the front opening portion 9 formed below the open / close door 4 rising. The positive pressure chamber 2 is provided with a fan 6 hepa filter 7 inside the outer box 5 and sucks outside air into the box through the prefilter 8 from outside the box. The air that has passed through the hepa filter 7 and has been purified is discharged from the ceiling of the clean work space 2 into the space 2.

清浄作業空間２の前面開口部９を覆うように設けた開閉扉４は、垂直に立てたガイドレール１０，１０に案内され、垂直方向に上下動可能とし、後述する支持手段２０により適宜位置に静止させ得る。開閉扉４は図３に示す如く外枠体１１とその内側に軸１２で支持された透明体よりなるスイスルーシャッター１３とよりなり、両者は連杆１４で連結され、軸１２を中心に所定角度開き開角度を一定に出来るよう図１に示す如くスイスルーシャッター１３の両側縁に接するよう開扉時ストッパー１５を設けている。図３に示す１６はつまみ、１７は閉扉時ストッパーである。   The open / close door 4 provided so as to cover the front opening 9 of the cleaning work space 2 is guided by guide rails 10 and 10 standing vertically, and can be moved up and down in the vertical direction. Can be stationary. As shown in FIG. 3, the open / close door 4 includes an outer frame body 11 and a Swiss Lou shutter 13 made of a transparent body supported by a shaft 12 on the inner side thereof. As shown in FIG. 1, the door opening stopper 15 is provided so as to be in contact with both side edges of the Swiss-Lo shutter 13 so that the angle opening angle can be made constant. In FIG. 3, 16 is a knob, and 17 is a stopper when the door is closed.

清浄作業空間２で作業を行うときは、図１に示す如く作業者は開閉扉４を上昇させ清浄作業空間２の前面開口部９に作業者の手を挿入出来る間隙を作り、手を清浄作業空間２内に挿入して作業を行なっている。このとき、開閉扉４のスイスルーシャッター１３は図１に示す如く上部を清浄作業空間２内に押し込まれており、スイスルーシャッター１３はヘパフィルター７からの清浄空気流の中に位置することになり、例えば作業者の顔が開閉扉４に近づいて、作業者の呼気がスイスルーシャッター１３に当たり、シャッター面が曇るというようなことは生じない。また、ヘパフィルター７から送出された天井近くの気流も、渦流となって該部に滞溜するようなこともない。   When working in the clean work space 2, as shown in FIG. 1, the worker raises the door 4 to create a gap in which the operator's hand can be inserted into the front opening 9 of the clean work space 2 to clean the hand. It is inserted into the space 2 for work. At this time, the Swiss Lou shutter 13 of the door 4 is pushed into the clean working space 2 as shown in FIG. 1 and the Swiss Lou shutter 13 is positioned in the clean air flow from the hepa filter 7. Thus, for example, it does not occur that the operator's face approaches the open / close door 4 and the operator's exhalation hits the Swiss shutter 13 and the shutter surface becomes cloudy. Further, the air current near the ceiling sent out from the hepa filter 7 does not become a vortex and stay in the portion.

上記開閉扉４は、上述の如くスイスルーシャッター１３を有し、作業中はその上端を図１に示す如く清浄作業空間２側に倒して作業をしているが、何等かの都合で更に前部開口部９の開口程度を大きくしたい場合が生ずる。その際にスイスルーシャッター１３の上部が、清浄作業空間２内に倒れ込んだままの状態で開閉扉３を上昇するとスイスルーシャッター１３が周囲の装置等と当接して障害を生ずる恐れがある。そこで、スイスルーシャッター１３を開いたまま開閉扉４を上昇してもスイスルーシャッター１３は開閉扉４の外枠体１１内に自動的に収納された状態となって開閉扉４が上昇出来るようにしたのがスイスルーシャッター安全機構１８である。   The opening / closing door 4 has the Swiss shutter 13 as described above, and the upper end of the opening / closing door 4 is tilted toward the clean work space 2 as shown in FIG. There is a case where it is desired to increase the degree of opening of the opening 9. At that time, if the upper part of the Swiss-Lu shutter 13 is raised in the clean work space 2 and the door 3 is raised, the Swiss-Lu shutter 13 may come into contact with surrounding devices and cause a failure. Therefore, even if the open / close door 4 is lifted with the Swiss-Lu shutter 13 open, the Swiss-Lu shutter 13 is automatically stored in the outer frame 11 of the open / close door 4 so that the open / close door 4 can be raised. The Swiss-Lou shutter safety mechanism 18 is used.

スイスルーシャッター安全機構１８は、開閉扉４のスイスルーシャッター１３の両側縁上端部の昇降軌跡に添って設けられ、スイスルーシャッター１３の側縁上端に当接するガイド板１９よりなる。図５に清浄作業空間２側に上部先端を倒したスイスルーシャッター１３（開閉扉の外枠体１１の上部は省略して示す）の上昇過程を示している。   The Swiss-Leu shutter safety mechanism 18 includes a guide plate 19 that is provided along the up-and-down trajectory of the upper ends of both side edges of the Swiss-Lu shutter 13 of the open / close door 4 and abuts on the upper side edge of the Swiss-Lu shutter 13. FIG. 5 shows the ascending process of the Swiss Lou shutter 13 (the upper part of the outer frame 11 of the opening / closing door is omitted) with the upper end tilted toward the cleaning work space 2 side.

図５に実線で示すスイスルーシャッター１３ａがその上部先端部を清浄作業空間２側に倒した状態のときに開閉扉４の外枠体１１を引き上げると外枠体１１の引き上げによってスイスルーシャッター１３ａの頂部はガイド板１８に当接する（１３ｂ）。そして更に外枠体１１の上昇によりスイスルーシャッター１３は１３ｃ，１３ｄと次第に直立し外枠体１１と同一平面状態となって陽圧室３の前面の収納部位に収まり清浄作業空間２の前面開口部９を開くことになる。   When the Swiss frame shutter 13a shown by the solid line in FIG. 5 is in a state in which the upper end portion thereof is tilted toward the cleaning work space 2 side, when the outer frame body 11 of the opening / closing door 4 is pulled up, the Swiss frame shutter 13a is lifted by the lifting of the outer frame body 11. The top of the abuts against the guide plate 18 (13b). Further, as the outer frame body 11 rises, the Swiss shutter 13 gradually rises up to 13c and 13d and becomes flush with the outer frame body 11 so that it fits in the storage part on the front surface of the positive pressure chamber 3 and opens to the front surface of the clean work space 2. Part 9 will be opened.

図６，図７に開閉扉４を上昇し、前面開口部９（図１に記載）を開いた際に、スイスルーシャッター１３が開閉扉４の上昇と共に清浄作業空間２側に傾斜して開くことを可能とした機構について説明する。前述の例と同一構造の部分は同一の符号を付して説明する。開閉扉４は、その両側に設けられた断面コ字状のガイドレール１０，１０に挟持されて上下動可能に支持されている。そして該開閉扉４の清浄作業空間２側には、清浄作業空間２側に傾斜したスイスルーシャッター１３の両側面に対向する位置にガイド溝２１を有するガイドレール２２を設け、スイスルーシャッター１３の側面に設けた支持部材２３から突出するピン２４を前記ガイド溝２１に嵌合している。   6 and 7, when the open / close door 4 is raised and the front opening 9 (described in FIG. 1) is opened, the Swiss shutter 13 is tilted and opened to the clean work space 2 side as the open / close door 4 is raised. The mechanism that made this possible will be described. Parts having the same structure as in the above-described example will be described with the same reference numerals. The open / close door 4 is sandwiched between U-shaped guide rails 10 and 10 provided on both sides of the door 4 so as to be vertically movable. A guide rail 22 having guide grooves 21 is provided on the clean work space 2 side of the open / close door 4 at positions facing both side surfaces of the Swiss Lou shutter 13 inclined to the clean work space 2 side. A pin 24 protruding from a support member 23 provided on the side surface is fitted in the guide groove 21.

前記ガイド溝２１は、ガイドレール２２に直線状に垂直に設けられているが、下位の一部は屈曲し清浄作業空間２側に突出し、突出部分２１ａを構成している。突出部分２１ａは、図７に示す如く直線状のものでもカーブを画いた屈曲線でも良い。前記突出部分２１ａの長さが長い程スイスルーシャッター１３の開いている部分が長いという事になる。   The guide groove 21 is linearly perpendicular to the guide rail 22, but a lower part of the guide groove 21 is bent and protrudes toward the cleaning work space 2 to constitute a protruding portion 21 a. The protruding portion 21a may be a straight line as shown in FIG. The longer the length of the protruding portion 21a, the longer the open portion of the Swiss roux shutter 13 is.

その動きについて次に説明する。開閉扉４の上昇により開閉扉４の外枠体１１にピン１２より枢支されているスイスルーシャッター１３は、上昇すると共にガイド溝２１に嵌合したピン２４も上昇しピン２４がガイド溝の突出部分２１ａに来るとスイスルーシャッター１３ｂは軸１２を中心にして頂部を清浄空間２方向に旋回して倒し、突出部分２１ａを通過するとスイスルーシャッター１３ｃは元位置に直立する。上記スイスルーシャッター１３の直立により開閉扉４は閉じクリーンベンチ１の外函５前面に収納される。   The movement will be described next. When the door 4 is raised, the Swiss shutter 13 pivotally supported by the outer frame 11 of the door 4 from the pin 12 is raised, and the pin 24 fitted in the guide groove 21 is also raised, so that the pin 24 is a guide groove. When it comes to the protruding portion 21a, the Swiss Lou shutter 13b turns around the axis 12 in the direction of the clean space 2 and falls down, and when passing through the protruding portion 21a, the Swiss Lou shutter 13c stands upright at its original position. The open / close door 4 is closed by the upright position of the Swiss Lou shutter 13 and stored in the front surface of the outer box 5 of the clean bench 1.

前記開閉扉４の昇降に際し、開閉扉４を適宜任意の位置に停止させ得るようにするために、開閉扉４の重量に見合ったスプリングの弾性を利用する例を図８に示す。
２５は帯状のコンストンバネで、軸支された巻取ロール２６に端部を固定し巻き取られ、コンストンバネ収容ボックス２７内に巻き込まれた状態で、引き出し可能に収容されている。コンストンバネ収容ボックス２７は、清浄作業空間２の前面上部天井部に設けられている。コンストンバネ２５の引き出し側先端には縦断面ほぼＵ字状の受け金具２８を設けている。受け金具２８は、開閉扉４の下縁に係止している。コンストンバネ２５のバネ力は開閉扉４の重量とバランスを取ってあり、扉４の開閉時には扉４に手を添えることで容易に開閉動させることが出来る。尚、開閉扉４が最上昇したときには、受け金具２８がコンストンバネ収容ボックス２７に当接し、収容ボックス２７がストッパーの役目をすることで開閉扉４の上昇を停止させる。 FIG. 8 shows an example in which the elasticity of the spring corresponding to the weight of the open / close door 4 is used so that the open / close door 4 can be appropriately stopped at an arbitrary position when the open / close door 4 is raised and lowered.
Reference numeral 25 denotes a belt-shaped conston spring which is wound around with its end fixed to a winding roll 26 that is pivotally supported, and accommodated in a conston spring accommodating box 27 so that it can be pulled out. The conston spring accommodating box 27 is provided in the upper front ceiling portion of the cleaning work space 2. A receiving metal fitting 28 having a substantially U-shaped longitudinal section is provided at the leading end of the conston spring 25. The catch 28 is locked to the lower edge of the open / close door 4. The spring force of the conston spring 25 balances the weight of the door 4 and can be easily opened and closed by putting the hand on the door 4 when the door 4 is opened and closed. When the opening / closing door 4 is raised to the maximum, the metal fitting 28 comes into contact with the conston spring accommodation box 27, and the accommodation box 27 serves as a stopper to stop the raising of the opening / closing door 4.

本発明のクリーンベンチにあっては上記の如く清浄作業空間２における作業時に開閉扉４のスイスルーシャッター１３の頂部を清浄作業空間２の内部側に倒すことによって、陽圧室３からヘパフィルター７を通過して吹き出された清浄空気を、前記スイスルーシャッターに案内させてクリーンベンチ外に導くことになるので、清浄作業空間２の上部空間の一部に渦流状の滞溜の生ずるのを防ぐことになり、またスイスルーシャッターの内外の面に添って清浄空気は流れることになりシャッター面の曇りなど生ずることもない。   In the clean bench according to the present invention, the top of the Swiss shutter 13 of the open / close door 4 is tilted to the inside of the clean work space 2 when working in the clean work space 2 as described above, whereby the hepa filter 7 is moved from the positive pressure chamber 3. Since the clean air blown out through the air is guided to the outside of the clean bench by being guided by the Swiss Lou shutter, it is possible to prevent the occurrence of swirling stagnation in a part of the upper space of the clean work space 2. In addition, clean air will flow along the inner and outer surfaces of the Swiss Lou shutter, and there will be no fogging of the shutter surface.
