Description

この発明は、工作機械の主軸の嵌合穴やその工具ホルダの工具チャッキング穴（取付穴）などの機械部品を清掃する工作機械部品用クリーナに関するものである。 The present invention relates to a cleaner for machine tool parts that cleans machine parts such as a fitting hole for a spindle of a machine tool and a tool chucking hole (mounting hole) for a tool holder thereof.

工作機械の主軸には、工具ホルダを介して各種の工具が取付けられる。その主軸への工具ホルダの取付けや工具ホルダへの工具の取付けは、主軸の嵌合穴に工具ホルダのシャンクを嵌め込んだり、工具ホルダの工具チャッキング穴に工具のシャンクを嵌め込んだりして行う。
このシャンクの嵌め込み方式として、図８（ｂ）に示すＢＴシャンク式（ＭＡＳ規格）等が一般的であるが、近年では、工作機械主軸と工具ホルダを結合する際の精度や剛性を高めるために、その結合部をテーパ面とフランジ面で拘束する２面拘束方式が採用されている。この方式のシャンクは中空シャンクと呼ばれ、中空・ショートテーパが特徴である。例えば、ＨＳＫ規格等がこれに該当する（図９〜図１１参照）。 Various tools are attached to the spindle of the machine tool via a tool holder. To attach the tool holder to the spindle or to the tool holder, insert the shank of the tool holder into the fitting hole of the spindle, or insert the shank of the tool into the tool chucking hole of the tool holder. conduct.
The BT shank type (MAS standard) shown in FIG. 8B is generally used as the shank fitting method, but in recent years, in order to improve the accuracy and rigidity when connecting the machine tool spindle and the tool holder. , A two-sided restraint method is adopted in which the joint portion is restrained by a tapered surface and a flange surface. This type of shank is called a hollow shank and is characterized by a hollow and short taper. For example, the HSK standard and the like correspond to this (see FIGS. 9 to 11).

その何れのシャンク式（規格）であっても、嵌合穴の内面や工具ホルダのシャンク外周面、工具チャッキング穴は、切削油や切削屑が入り込んだり付着したりするため、定期的に清掃する必要がある。
このため、従来から、様々な工作機械部品等に形成された空洞部（穴）等を清掃するための種々のクリーナ（清掃具）が提案されている。例えば、把持部とこれの先端に連設した棒状清掃部とを有し、その清掃部の外周面長さ方向に清掃体を設けたものがある（特許文献１、実用新案登録請求の範囲、第１図、第２図等参照）。
このクリーナは、例えば、主軸の嵌合穴に把持部を持って清掃部を挿入し、把持部をその軸回りに回転させて嵌合穴内面に清掃体を摺接することにより、清掃体で嵌合穴内面を清掃する。 Regardless of the shank type (standard), the inner surface of the fitting hole, the outer surface of the shank of the tool holder, and the tool chucking hole are cleaned regularly because cutting oil and cutting debris get in and adhere to them. There is a need to.
For this reason, various cleaners (cleaning tools) for cleaning cavities (holes) formed in various machine tool parts and the like have been conventionally proposed. For example, there is a case in which a grip portion and a rod-shaped cleaning portion connected to the tip of the grip portion are provided, and a cleaning body is provided in the direction of the outer peripheral surface length of the cleaning portion (Patent Document 1, Claims for Utility Model Registration, (See Fig. 1, Fig. 2, etc.).
This cleaner is fitted with the cleaning body by, for example, inserting the cleaning portion by holding the grip portion into the fitting hole of the spindle, rotating the grip portion around the shaft, and sliding the cleaning body against the inner surface of the fitting hole. Clean the inner surface of the hole.

特に、上記ＨＳＫ規格等の中空テーパシャンクの結合部（嵌合穴）のクリーナは、クランプ部品（例えば、図１０（ｂ）のドロバーＤ、コレットＣ_１参照）を回避しながら主軸の嵌合穴を清掃するために、薄肉で弾性当接する清掃部を備える必要がある（特許文献２、図1、図２、図３等参照）。
また、清掃体を清掃部から着脱可能としたクリーナもある（特許文献３図１〜図５参照）。 In particular, the HSK cleaner coupling portion of the hollow taper shank standard like (fitting hole) is clamped components (e.g., Doroba D, collet reference C ₁ in FIG. 10 (b)) the fitting hole of the spindle while avoiding It is necessary to provide a cleaning portion that is thin and elastically contacts in order to clean the surface (see Patent Document 2, FIG. 1, FIG. 2, FIG. 3, etc.).
There is also a cleaner in which the cleaning body can be attached to and detached from the cleaning portion (see Patent Documents 3 and 1 to 5).

上記クリーナの従来品は、清掃体がセーム皮等からなって、その清掃体を棒状清掃部の外面に接着で固定している。また、前記外面の溝に清掃体を嵌め込んでいるものもあるが、その嵌め込みは、清掃体の清掃部外周面への位置決めであり、清掃体は溝内に接着固定している（特許文献１明細書第２頁第３欄第２９〜３０行、第２図参照）。
清掃体は、損傷や汚れがひどいため、頻繁に取り替える必要がある。しかし、上記のように、従来は、セーム皮等の清掃体を接着等で固定しているため、容易に剥ぎ取ることができず、その交換が容易でなかった。
清掃体を着脱可能にしたクリーナは、その清掃体両端のフック（特許文献３図５の符号４５、５０参照）を清掃部に係止してその着脱を可能としているため、その取り付け強度が低い場合があり、清掃中に外れる恐れがある。 In the conventional cleaner, the cleaning body is made of chamois or the like, and the cleaning body is fixed to the outer surface of the rod-shaped cleaning portion by adhesive. In some cases, the cleaning body is fitted into the groove on the outer surface, but the fitting is positioning of the cleaning body on the outer peripheral surface of the cleaning portion, and the cleaning body is adhesively fixed in the groove (Patent Document). 1 Specification, page 2, column 3, lines 29 to 30, see FIG. 2).
The cleaning body is severely damaged and dirty and needs to be replaced frequently. However, as described above, conventionally, since the cleaning body such as chamois is fixed by adhesive or the like, it cannot be easily peeled off and its replacement is not easy.
The cleaner that makes the cleaning body removable has low mounting strength because the hooks at both ends of the cleaning body (see reference numerals 45 and 50 in FIG. 5 of Patent Document 3) are locked to the cleaning portion so that the cleaning body can be attached and detached. In some cases, it may come off during cleaning.

また、特に、ＨＳＫ規格等の主軸の嵌合穴においては、工具ホルダＴ_３の開口部内径ｓが１４ｍｍ程度から６７ｍｍの大小様々のものがあり（図１０参照）、その内径ｓに入るクランプ部品（上記図１０（ｂ）のドロバーＤ等）も同等の外径であるため、布やペーパーなどを使って手で拭く場合に指が入らず、さらに指が入る大きさの穴であっても、クランプ部品が穴の開口付近に存在するため、指が入らず清掃が困難である。さらに、そのクランプ部品を回避しながら主軸の嵌合穴を清掃するために、薄肉で弾性当接する清掃部を備える必要がある（特許文献２、図1、図２、図３等参照）。 In particular, in the fitting hole of the main shaft, such as HSK standard, opening the inner diameter s of the tool holder _{T 3} There are those from about 14mm of the various magnitudes of 67 mm (see FIG. 10), the clamp parts to enter the inner diameter s (Drobar D, etc. in FIG. 10 (b) above) has the same outer diameter, so even if the hole is large enough to hold a finger, it will not fit when wiped by hand with a cloth or paper. Since the clamp part is located near the opening of the hole, it is difficult to clean it because fingers cannot enter it. Further, in order to clean the fitting hole of the spindle while avoiding the clamp component, it is necessary to provide a cleaning portion that is thin and elastically contacts (see Patent Document 2, FIG. 1, FIG. 2, FIG. 3 and the like).

この発明は、以上の実状の下、清掃体の十分な取り付け強度を担保でき、かつ清掃体を容易に取り付け・取り外しし得るようにすることを課題とする。 It is an object of the present invention to ensure sufficient attachment strength of the cleaning body under the above-mentioned actual conditions, and to make it possible to easily attach / detach the cleaning body.

上記課題を解決するために、この発明は、棒状清掃体をクリーナ本体の開口幅狭の溝に嵌めて取り付けることとしたのである。棒状清掃体は溝に嵌った後は、幅狭の開口から抜け出なくなって取り付け強度が高いものとなる。
具体的には、円筒状（円錐状も含む）被清掃面のその周面に沿って清掃体を摺接させる工作機械部品用クリーナにおいて、前記清掃体は、清掃部となる棒状クリーナ本体の前記被清掃面に対向する清掃面にその軸方向の溝に嵌って取り付けられており、その溝の長さ方向の開口は内側より幅狭に形成されている構成としたのである。
清掃体は溝に嵌められることから棒状であり、その溝への嵌め込みは、溝の端面開口から清掃体を溝内に挿し通したり、幅狭の開口から清掃体を押し込んだり等して行う。
なお、この発明でいう「棒状」は、筒状の中空の棒状のみならず、無垢（中実）の棒状も含む。 In order to solve the above problems, in the present invention, the rod-shaped cleaning body is fitted and attached to the groove having a narrow opening width of the cleaner body. After the rod-shaped cleaning body is fitted in the groove, it cannot be pulled out from the narrow opening and the mounting strength is high.
Specifically, in a cleaner for machine tool parts in which a cleaning body is slidably contacted along the peripheral surface of a cylindrical (including conical) surface to be cleaned, the cleaning body is the rod-shaped cleaner main body serving as a cleaning portion. It is attached to the cleaning surface facing the surface to be cleaned by fitting it into a groove in the axial direction, and the opening in the length direction of the groove is formed to be narrower than the inside.
Since the cleaning body is fitted into the groove, it has a rod shape, and the cleaning body is fitted into the groove by inserting the cleaning body into the groove through the end face opening of the groove, pushing the cleaning body through the narrow opening, or the like.
The "rod shape" referred to in the present invention includes not only a cylindrical hollow rod shape but also a solid (solid) rod shape.

上記クリーナ本体は、同一太さの棒状体、例えば、円柱、円筒、角柱、角筒であったり、円錐状や角錐状のテーパ外周面を有する棒状体としたりすることができるが、その先端部が軸方向所要長さ（図３のＬ参照）同一太さとなってその同一太さ部分から後端に向かって徐々に太くなっている構成とすることができる。例えば、先端部が同一径の円柱状、その円柱状部分（前記所要長さ部分の後端）から後方に向かって徐々に径が大きくなる円錐柱状のテーパ面を有するものとすることができる。前記軸方向所要長さ及びテーパの角度（図１のθ参照）は、下記拭き取りが円滑に行われるように、被清掃面の形状や大きさ等に応じて実験などによって適宜に設定する。
なお、断面形状が円形以外の場合のクリーナ本体の先端部が軸方向所要長さ「同一太さとなっている」とは、クリーナ本体の外周面の各棒状清掃体が描く外周面（外接面、図６（ａ）（ｂ）のｒ_１参照）の径が同一の意であり、「徐々に太くなっている」とは、同各棒状清掃体が描く外周面の径が後側に向かって徐々に大きくなるテーパ面となる意である。 The cleaner body may be a rod-shaped body having the same thickness, for example, a cylinder, a cylinder, a prism, a square cylinder, or a rod-shaped body having a conical or pyramidal tapered outer peripheral surface. Is the required length in the axial direction (see L in FIG. 3), and the thickness can be gradually increased from the same thickness portion toward the rear end. For example, the tip portion may have a columnar shape having the same diameter, and may have a conical columnar tapered surface whose diameter gradually increases from the columnar portion (the rear end of the required length portion) to the rear. The required axial length and taper angle (see θ in FIG. 1) are appropriately set by experiments or the like according to the shape and size of the surface to be cleaned so that the following wiping can be performed smoothly.
When the cross-sectional shape is other than circular, the required length in the axial direction "the same thickness" means that the outer peripheral surface (circumscribed surface, outer contact surface) drawn by each rod-shaped cleaning body on the outer peripheral surface of the cleaner body. a meaning diameter identical in r reference ₁₎ in FIG. 6 (a) (b), the term "gradually becomes thicker", toward the diameter rear side of the outer peripheral surface of the respective rod-like cleaning element is drawn It is meant to be a tapered surface that gradually increases.

以上の構成において、上記棒状清掃体が弾性材からなれば、被清掃面に清掃体を強く押し当て回転させると、清掃体は収縮して溝内周面全体にその押し当て圧力でさらに密着度が増すため、円柱状等の棒状の清掃体であっても溝の中で回転するようなことがなく、取り付け強度はより高いものとなって、被清掃面に強く押し当てられて汚れを確実にとらえて剥ぎ取る。また、被清掃面に凹凸等があってその形状が歪（いびつ）であったり面にわずかな窪みがあったりしても、清掃体がその弾力によってその歪な形状などに倣うため、清掃が円滑に行われる。
このとき、清掃体が円柱状（円筒状も含む）であれば、円筒状被清掃面に対向する清掃面はほぼ線（状）当たりになる。この線当たりの弾性線状体は面状当たりの清掃体よりも被清掃面の形状にフィットし易い。このため、清掃効果も高いものとなる。
さらに、上記清掃体が被清掃面に線当たりとなれば、清掃体の間隔も自ずと広くなって（清掃体の間隔を十分確保することができ）、その間において、剥ぎ取ったゴミなどの汚れを一時的に貯めるスペースを大きく確保できる。また、清掃体をクリーナ本体（回転円周上）に配置する数を多く設置することができる。回転円周上に清掃体が多く配置されれば、回転角が小さくても全面を清掃でき、清掃効率が高いものとなる。 In the above configuration, if the rod-shaped cleaning body is made of an elastic material, when the cleaning body is strongly pressed against the surface to be cleaned and rotated, the cleaning body contracts and the pressing pressure further adheres to the entire peripheral surface of the groove. Even if it is a rod-shaped cleaning body such as a columnar shape, it will not rotate in the groove, and the mounting strength will be higher, and it will be strongly pressed against the surface to be cleaned to ensure dirt. Catch it and peel it off. In addition, even if the surface to be cleaned has irregularities and the shape is distorted or the surface has slight dents, the cleaning body follows the distorted shape due to its elasticity, so cleaning can be performed. It will be done smoothly.
At this time, if the cleaning body is cylindrical (including cylindrical), the cleaning surface facing the cylindrical surface to be cleaned is substantially in line (shape). The elastic linear body per wire is more likely to fit the shape of the surface to be cleaned than the cleaning body per surface. Therefore, the cleaning effect is also high.
Further, if the cleaning body comes into contact with the surface to be cleaned, the space between the cleaning bodies is naturally widened (the space between the cleaning bodies can be sufficiently secured), and in the meantime, dirt such as peeled dust is removed. A large space for temporary storage can be secured. In addition, a large number of cleaning bodies can be installed on the cleaner body (on the circumference of the rotation). If many cleaning bodies are arranged on the circumference of the rotation, the entire surface can be cleaned even if the rotation angle is small, and the cleaning efficiency becomes high.

棒状の弾性材は、上記円柱状、円筒状や角柱状、角筒状等と任意であるが、清掃体が筒状（中空）であれば、変形量の度合いが大きいため、被清掃面の形状へのフィット性も向上し、清掃効果もより高いものとなるとともに、径方向の伸縮が容易となって弾性体の清掃体を溝に押し込むことがより容易となる。さらに、清掃体は端面に開口する孔を有するものとなるため、端面の孔に棒材等を差し込み、その棒材を介して清掃体を溝から引き出せば、溝から清掃体を容易に取り出すことができる。この端面開口は、筒状の中空の物に限らず、無垢（中実）の棒状体であっても、その端面に棒材等の差し込み孔を別途に形成して設けるようにし得る。 The rod-shaped elastic material may be cylindrical, cylindrical, prismatic, square-cylindrical, or the like, but if the cleaning body is tubular (hollow), the degree of deformation is large, so that the surface to be cleaned The fit to the shape is also improved, the cleaning effect is enhanced, and the expansion and contraction in the radial direction becomes easy, and it becomes easier to push the cleaning body of the elastic body into the groove. Further, since the cleaning body has a hole that opens on the end face, if a bar or the like is inserted into the hole on the end face and the cleaning body is pulled out from the groove through the bar, the cleaning body can be easily taken out from the groove. Can be done. The end face opening is not limited to a hollow cylindrical object, and even if it is a solid (solid) rod-shaped body, an insertion hole for a rod material or the like may be separately formed on the end surface thereof.

ここで、穴内面からなる被清掃面が全長に亘って同一径の円筒状であると、通常、穴内面とクリーナ本体外面とに隙間が生じるため、クリーナをその軸心回りに回転させるだけではきれいに拭き取れない恐れがある。しかし、清掃体が弾性材からなれば、清掃体が膨縮して穴内面に倣い同径となるため、クリーナを穴に押し込むことができ、押し込めれば、回転させて綺麗に拭き取ることができる。このとき、上記のように、先端部が軸方向所要長さ同一太さとなってその同一太さ部分から後端に向かって徐々に太くなっていると、例えば、図３に示すクリーナＡ_２のように、テーパ面とストレート面が連続しているものにあっては、この作用による利点が顕著となる。 Here, if the surface to be cleaned consisting of the inner surface of the hole has a cylindrical shape having the same diameter over the entire length, a gap is usually generated between the inner surface of the hole and the outer surface of the cleaner body. Therefore, simply rotating the cleaner around its axis is sufficient. It may not be wiped clean. However, if the cleaning body is made of an elastic material, the cleaning body expands and contracts to follow the inner surface of the hole and have the same diameter, so the cleaner can be pushed into the hole, and if pushed in, it can be rotated and wiped clean. .. At this time, as described above, if the tip portion has the same thickness as the required length in the axial direction and gradually becomes thicker from the same thickness portion toward the rear end, for example, the cleaner A _{2 shown in FIG.} As described above, in the case where the tapered surface and the straight surface are continuous, the advantage of this action becomes remarkable.

さらに、溝の縦断面積に対し弾性材からなる棒状清掃体の縦断面積を大きくすれば、清掃体を溝に嵌める際、清掃体が収縮して溝内に押し込まれるため、嵌った後、清掃体は自身の弾力によって溝内周面全体に密着して十分な取り付け強度を有するものとなる。すなわち、溝の縦断面は開口が切り欠けた円形状であり、清掃体も縦断面円形状であり、溝の円形状径ｄと清掃体の円形状径ｒとの関係を（ｄ＜ｒ）とする。例えば、その比を、０．８５≦ｄ／ｒ≦０．９７とすることができる。ｄ／ｒが０．８未満であると、溝に清掃体を押し込みにくくなって作業性が悪くなり、一方、０．９７を超えると、溝に嵌った清掃体の反発弾力が十分でなく、十分な取り付け強度を担保できない場合がある。 Further, if the vertical cross-sectional area of the rod-shaped cleaning body made of an elastic material is increased with respect to the vertical cross-sectional area of the groove, the cleaning body contracts and is pushed into the groove when the cleaning body is fitted into the groove. Due to its own elasticity, it adheres to the entire peripheral surface of the groove and has sufficient mounting strength. That is, the vertical cross section of the groove has a circular shape with a notched opening, and the cleaning body also has a circular vertical cross section. And. For example, the ratio can be 0.85 ≦ d / r ≦ 0.97. If d / r is less than 0.8, it becomes difficult to push the cleaning body into the groove and workability deteriorates, while if it exceeds 0.97, the repulsive elasticity of the cleaning body fitted in the groove is not sufficient. Sufficient mounting strength may not be guaranteed.

上記各構成の工作機械部品用クリーナにおいて、円筒状被清掃面の端にその外側又は内側に延びる被清掃端面を有するものにあっては、上記清掃面の端に、前記被清掃端面に対向する清掃端面を有し、その清掃端面に前記外側又は内側に延びる溝に棒状清掃体が嵌って取り付けられており、その溝の長さ方向の開口は内側より幅狭に形成されている構成とすることができる。
このようにすれば、穴などの円筒状被清掃面のみならず、その清掃時に、その外側又は内側に延びる被清掃端面を清掃することができる。 In the cleaners for machine tool parts having each of the above configurations, in the case where the cylindrical cleaner to be cleaned has an end surface to be cleaned extending outward or inward, the end of the surface to be cleaned faces the end surface to be cleaned. It has a cleaning end face, and a rod-shaped cleaning body is fitted into the groove extending to the outside or inside of the cleaning end face, and the opening in the length direction of the groove is formed to be narrower than the inside. be able to.
In this way, not only the cylindrical surface to be cleaned such as a hole, but also the end surface to be cleaned extending to the outside or the inside can be cleaned at the time of cleaning.

また、上記クリーナ本体の外周面に起伏片を設け、その起伏片の外面に清掃体を設ければ、その起伏片の起伏度合いに応じた大きさ（径）の穴内面の清掃を行うことができる。このため、鍔Ｆ等のクランプ部品が穴の開口付近にあっても（図９参照）、起伏片の倒伏によってそのクランプ部品を回避できてその穴を清掃することができる。 Further, if an undulating piece is provided on the outer peripheral surface of the cleaner main body and a cleaning body is provided on the outer surface of the undulating piece, the inner surface of the hole having a size (diameter) according to the degree of undulation of the undulating piece can be cleaned. can. Therefore, even if a clamp component such as a collar F is near the opening of the hole (see FIG. 9), the clamp component can be avoided by the undulation of the undulating piece, and the hole can be cleaned.

上記クリーナ本体は棒状清掃部からなり、その清掃部に把持棒を取り外し可能に延設したものとすれば、把持棒を外すことによって、狭い場所に清掃部を導いて清掃することができ、例えば、清掃部をその後面を掌で押しながら回すことによって清掃作業を行うことができる。
その把持棒を筒状とすれば、その筒状内部に予備の清掃体や他の部材等を収納することができる。このとき、その収納スペースの開口はねじ込み式やビス止めなどとし得る蓋で閉じることができる。さらに、把持棒や蓋には磁石を内蔵したり、付着させたり、フックを設けたり、チェーン等のストラップを設けたり等して、工作機械周辺やその部品収納スペース、作業スペースにクリーナを設置し易い手段を設けることができる。 If the cleaner body is composed of a rod-shaped cleaning portion and the gripping rod is detachably extended to the cleaning portion, the cleaning portion can be guided to a narrow place for cleaning by removing the gripping rod, for example. The cleaning work can be performed by turning the cleaning unit while pushing the rear surface with the palm.
If the gripping rod has a cylindrical shape, a spare cleaning body, other members, and the like can be stored inside the cylindrical shape. At this time, the opening of the storage space can be closed with a lid that can be screwed or screwed. In addition, magnets are built into the grip rods and lids, attached to them, hooks are provided, straps such as chains are provided, and cleaners are installed around the machine tool, its parts storage space, and work space. Easy means can be provided.

この発明は、以上のように構成したので、清掃体の十分な取り付けを担保でき、かつ清掃体の取り付け・取り外しを容易に行うことができる。 Since the present invention is configured as described above, sufficient attachment of the cleaning body can be ensured, and attachment / detachment of the cleaning body can be easily performed.

この発明に係るクリーナの一実施形態を図１、図２に示し、この実施形態のクリーナＡ_１（以下、Ａ_２等を含めて、総称符号：Ａ）は、図８に示すマシニングセンターの主軸（main spindle）Ｍの工具ホルダ嵌合穴Ｈ等を清掃するものであり、円錐台状のクリーナ本体１０と、そのクリーナ本体１０の後端に連設される把持棒２０とからなる。クリーナ本体１０、把持棒２０は金属や樹脂製とする。嵌合穴Ｈは、通常、芯を取るため円錐台状である。 An embodiment of the cleaner according to the present invention is shown in FIGS. 1 and 2, and the cleaner A ₁ of this embodiment (hereinafter _{, generic reference numeral: A including A 2 and the} like) is the spindle of the machining center shown in FIG. It cleans the tool holder fitting hole H and the like of the main spindle) M, and includes a truncated cone-shaped cleaner main body 10 and a gripping rod 20 connected to the rear end of the cleaner main body 10. The cleaner body 10 and the gripping rod 20 are made of metal or resin. The fitting hole H is usually in the shape of a truncated cone for centering.

クリーナ本体１０は、前面開口１１ｃの中空円錐棒状であって、その外周面の周囲等間隔に長さ方向（軸方向）の溝１１が形成されている。清掃面となる外周面の傾斜度合い（テーパ度合θ）は、被清掃面となる穴内面の傾斜度合いに対応して適宜に設定すれば良いが、穴Ｈの円錐台状周面の傾斜度合と同じとすることができる。
溝１１の本数は任意であり、必ずしも等間隔である必要はない。要は、後述の清掃が円滑に行い得れば、その数や間隔は適宜であり、実験などによって適宜に決定すればよい。
溝１１は、縦断面一部（開口１１ｂ）欠如の円形をしている。このため、クリーナ本体１０の先端面の開口１１ａも一部が欠けた円状となって、同外周面の軸方向の開口１１ｂはその外周面全長に至っているとともに、その開口１１ｂの幅ｔ_１は円形溝１１の径ｔ_２より狭くなっている（ｔ_１＜ｔ_２）。その狭さ度合いは、下記の棒状清掃体１３を溝１１に嵌め込みし得る反面、摺動程度では抜け出ないように、実験等によって適宜に設定する。溝１１は、ドリル等で形成する。 The cleaner main body 10 has a hollow conical rod shape with a front opening 11c, and grooves 11 in the length direction (axial direction) are formed at equal intervals around the outer peripheral surface thereof. The degree of inclination of the outer peripheral surface to be the cleaning surface (tapering degree θ) may be appropriately set according to the degree of inclination of the inner surface of the hole to be cleaned, but it is the same as the degree of inclination of the truncated cone-shaped peripheral surface of the hole H. Can be the same.
The number of grooves 11 is arbitrary and does not necessarily have to be evenly spaced. In short, if the cleaning described later can be performed smoothly, the number and intervals thereof are appropriate, and may be appropriately determined by experiments or the like.
The groove 11 has a circular shape lacking a part of the vertical cross section (opening 11b). Therefore, a part opening 11a even in the distal end surface of the cleaner main body 10 is missing circular, with axial opening 11b of the outer peripheral surface is led to the outer peripheral surface entire length, width t ₁ of the opening 11b Is narrower than _{the diameter t 2} of the circular groove 11 _{(t 1} <t ₂ ). The degree of narrowness is appropriately set by an experiment or the like so that the following rod-shaped cleaning body 13 can be fitted into the groove 11 but does not come off by the degree of sliding. The groove 11 is formed by a drill or the like.

清掃体１３は、オレフィン系熱可塑性連続気泡の多孔質プラスチック製の円筒状の棒状部材からなり、図１に示すように、溝１１に押し込み嵌め込みで取り付ける。このとき、清掃体１３が多孔質プラスチックの弾性材からなるため、収縮変形し易くその嵌め込みは容易である（図１（ｃ）の実線から鎖線参照）。また、前記気泡は微細であり、かつ清掃体表面が平滑であることから、嵌め込みは容易である。
棒状清掃体１３を溝１１に嵌め込めば、図１（ｂ）に示すように、清掃体１３は溝１１内に隙間無く入り込んで、溝１１の開口幅ｔ_１が径ｔ_２より狭くなっているため、清掃体１３が容易に抜け出る事はない。このため、円筒の清掃体１３であっても溝１１の中で回転するようなことがなく、取り付け強度の高いものとなる。
清掃体１３の材質は熱可塑性連続気泡の多孔質プラスチックに限らず、棒状清掃体とし得る弾性体であれば、何れでも良い。また、円筒状に限らず、角筒状であったり、無垢（中実）の円柱状であったり、角柱状であったりとし得る。このとき、筒状の中空であればさらに収縮変形しやすく、上記溝内への嵌り込みや清掃時の押圧力がさらに得られる等の好ましい態様となる。 The cleaning body 13 is made of a cylindrical rod-shaped member made of porous plastic with olefin-based thermoplastic open cells, and is attached to the groove 11 by pushing and fitting as shown in FIG. At this time, since the cleaning body 13 is made of an elastic material made of a porous plastic, it is easily contracted and deformed, and its fitting is easy (see the solid line to the chain line in FIG. 1C). Further, since the bubbles are fine and the surface of the cleaning body is smooth, fitting is easy.
When the rod-shaped cleaning body 13 is fitted into the groove 11, as shown in FIG. 1 (b), the cleaning body 13 enters the groove 11 without a gap, and the opening width t ₁ of the groove 11 becomes narrower than the diameter t _2. Therefore, the cleaning body 13 does not easily come out. Therefore, even the cylindrical cleaning body 13 does not rotate in the groove 11, and the mounting strength is high.
The material of the cleaning body 13 is not limited to the porous plastic of thermoplastic open cells, and any elastic body that can be used as a rod-shaped cleaning body may be used. Further, the shape is not limited to a cylinder, and may be a square cylinder, a solid (solid) cylinder, or a prism. At this time, if the cylinder is hollow, it is more easily contracted and deformed, which is a preferable mode such that the fitting into the groove and the pressing force at the time of cleaning can be further obtained.

クリーナ本体１０の後部は棒状把持部１４となって、その表面に綾目等のローレット加工１５が施されて滑り止めがなされている。この把持部１４の長さ（軸方向）は、その後面を掌に当てて外周面を把持できる程度とする。
把持棒２０は、上記クリーナ本体１０の円筒状把持部１４に差し込み可能となっており、把持部１４の孔１６から取り付けねじ１７をねじ孔２７にねじ込むことによってクリーナ本体１０に一体となる。把持棒２０にもローレット加工２５が施されて滑り止めがなされている。 The rear portion of the cleaner main body 10 is a rod-shaped grip portion 14, and the surface thereof is knurled 15 such as twill to prevent slipping. The length (axial direction) of the grip portion 14 is such that the rear surface thereof can be brought into contact with the palm to grip the outer peripheral surface.
The grip rod 20 can be inserted into the cylindrical grip portion 14 of the cleaner main body 10, and is integrated with the cleaner main body 10 by screwing the mounting screw 17 into the screw hole 27 from the hole 16 of the grip portion 14. The gripping rod 20 is also knurled 25 to prevent slipping.

このクリーナＡ_１によって、例えば、図８（ｂ）に示す、ＢＴシャンクの工具ホルダＴ_１用主軸Ｍにあっては、同図（ａ）に示すように、従来と同様に、円錐台状の穴ＨにクリーナＡ_１を差し込んでその軸心周りに回転することによって清掃する。このとき、通常、主軸Ｍの前方は広いスペースがあるため、把持棒２０は装着した状態で行う（同図鎖線状態）。図中、Ｄはドロバー、ＣはそのドロバーＤ先端の工具ホルダＴ_１のプルスタットＰの把持用コレットである。
マシニングセンター等の工具ホルダ収納ポットの穴清掃の場合は、その作業が狭いスペースで行うこととなる場合が多いため、図８（ａ）実線に示すように、把持棒２０を外して清掃する。この場合は、把持部１４の後面を掌に当てて外周面を把持して清掃を行う。
クリーナＡ_１のクリーナ本体１０の傾斜度合（図１のθ参照）と穴Ｈの円錐台状周面の傾斜度合が異なれば、クリーナＡ_１を穴Ｈの軸心に対し傾け回転等して穴Ｈ内周面全域に清掃体１３を摺接してその全域の汚れを除去する。 This cleaner A _1, for example, shown in FIG. 8 (b), In the tool holder T ₁ spindle M of BT shank, as shown in FIG. 6 (a), similarly to the conventional frustoconical cleaning by rotating its axis around insert the cleaner a ₁ into the hole H. At this time, since there is usually a large space in front of the main shaft M, the gripping rod 20 is attached in the mounted state (chain line state in the figure). In the figure, D is Doroba, C is a gripping collet of Doroba D tip Purusutatto P of the tool holder T ₁ of the.
When cleaning holes in a tool holder storage pot such as a machining center, the work is often performed in a narrow space. Therefore, as shown by the solid line in FIG. 8A, the gripping rod 20 is removed for cleaning. In this case, the rear surface of the grip portion 14 is placed against the palm to grip the outer peripheral surface for cleaning.
Different inclination degree of the frustoconical circumferential surface of the inclined degree (see θ in Fig. 1) and the hole H of the cleaner main body 10 of the cleaner A _1, hole cleaner A ₁ rotates like inclined relative to the axis of the hole H The cleaning body 13 is slidably contacted over the entire inner peripheral surface of H to remove dirt from the entire area.

清掃体１３が摩耗などして交換する場合、その交換は、例えば、図２鎖線に示すように、棒材３０を清掃体１３の中心孔１３ａに差し込んで持ち上げることによって行う。溝１１から清掃体１３が取り外されれば、新たな清掃体１３を溝１１に嵌め込む。棒材３０は図示のように、二本を一体としたものとすれば、二本の清掃体１３、１３を同時に取り外すことができる。清掃体１３は中心孔１３ａを有しない無垢の弾性体とし得る。 When the cleaning body 13 is replaced due to wear or the like, the replacement is performed, for example, by inserting the rod 30 into the central hole 13a of the cleaning body 13 and lifting it as shown by the chain line in FIG. When the cleaning body 13 is removed from the groove 11, a new cleaning body 13 is fitted into the groove 11. As shown in the drawing, if the two rods 30 are integrated, the two cleaning bodies 13 and 13 can be removed at the same time. The cleaning body 13 may be a solid elastic body having no central hole 13a.

クリーナ本体１０の形状としては、上記実施形態に限らず、被清掃面の形状・大きさ等に応じて適宜に決定すれば良い。例えば、図３に示すように、把持部１４の形状を変えたり、図４に示すように、ＨＳＫシャンク(中空テーパシャンク）に対応する、テーパ筒状部分とその縁の鍔部１０ａとに清掃面を有する中空のクリーナ本体１０としたりし得る。このとき、鍔部１０ａの面（側面）の上記溝１１と同一形状（ｔ_１＜ｔ_２）の溝１１に清掃体１３を嵌め込み取り付けする。 The shape of the cleaner main body 10 is not limited to the above embodiment, and may be appropriately determined according to the shape and size of the surface to be cleaned. For example, as shown in FIG. 3, the shape of the grip portion 14 is changed, and as shown in FIG. 4, the tapered tubular portion and the flange portion 10a at the edge thereof corresponding to the HSK shank (hollow taper shank) are cleaned. It may be a hollow cleaner body 10 having a surface. At this time, the cleaning body 13 is fitted and attached to the _{groove 11 having the same shape (t 1} <t ₂ ) as the groove 11 on the surface (side surface) of the flange portion 10a.

図３に示す実施形態のクリーナＡ_２は、クリーナ本体１０の先端部が同一径の筒状となっているため、例えば、図９に示すように、工具ホルダＴ_２の同一形状工具取り付け穴Ｈ等に嵌めてその内周面を清掃する。
このクリーナＡ_２の場合、被清掃面（嵌合穴Ｈ内面）が全長に亘って同一径の円筒状であると、通常、穴内面とクリーナＡ_２外面とに隙間が生じるため、クリーナＡ_２をその軸心回りに回転させるだけではきれいに拭き取れない恐れがある。しかし、清掃体１３が弾性材からなる円筒状であれば、清掃体１３が膨縮して穴内面に倣い同径となるため、クリーナＡ_２を穴に押し込むことができ、押し込めれば、回転させて綺麗に拭き取ることができる。特に、図３に示すクリーナＡ_２のように、テーパ面とストレート面が連続しているものにあっては、この作用による利点が顕著となる。 _{In the cleaner A 2} of the embodiment shown in FIG. 3, since the tip of the cleaner main body 10 has a cylindrical shape having the same diameter, for example, as shown in FIG. 9, the tool holder T _{2 has} the same shape tool mounting hole H. Clean the inner peripheral surface by fitting it into a cylinder.
In the case of the cleaner A ₂ , if the surface to be cleaned (inner surface of the fitting hole H) is cylindrical with the same diameter over the entire length _{, a gap is usually generated between the inner surface of the hole and the outer surface of the cleaner A 2,} so that the cleaner A ₂ There is a risk that it cannot be wiped clean just by rotating it around its axis. However, if the cleaning body 13 has a cylindrical shape made of an elastic material, the cleaning body 13 _{expands and contracts to have the same diameter as the inner surface of the hole, so that the cleaner A 2} can be pushed into the hole, and if pushed in, it rotates. It can be wiped clean. In particular, as the cleaner A ₂ shown in FIG. 3, the apparatus having the tapered surface and the straight surface is continuous, advantage of this effect becomes remarkable.

図４に示す実施形態のクリーナＡ_３は、例えば、図１０（ｂ）に示す、ＨＳＫシャンクの工具ホルダＴ_３用主軸Ｍにあって、同図（ａ）に示すように、従来と同様に、その穴ＨにクリーナＡ_３を差し込んで回転することによって清掃する。図中、Ｃ_１はドロバーＤ先端の工具ホルダＴ_３のＨＳＫ用コレットである。
通常、この種のテーパ筒状部分と鍔部１０ａとに清掃面を有するクリーナによって、図１０に示す、テーパ面と端面の２面を有する嵌合穴Ｈのその両面を同時に清掃する場合、テーパ筒状部分の清掃面が嵌合穴Ｈのテーパ面に当たると、鍔部１０ａの清掃面と嵌合穴Ｈの端面との間には隙間が生じ易い。このとき、ドロバー等の機械的な機構による引っ張り力（例えば、５７００Ｎ）であれば、テーパ面に当たる筒状部分を変形させたり、鍔部を変形させたりして鍔部１０ａの清掃面を嵌合穴Ｈの端面に当てることができるが、この種の清掃は手作業で行うため、そのクリーナの変形は容易ではなく殆ど不可能である。すなわち、手作業の力ではクリーナ本体１０等は変形し得ず、両面に清掃面を強く当てることはできない。しかし、このクリーナＡ_３の清掃体１３は弾性材からなる中空の円筒状であるため、その変形量を多く得やすい。このため、テーパ面と端面の２面を有する嵌合穴Ｈのその両面に対し、前記テーパ面にクリーナ本体１０の円錐台状外面（テーパ面）、前記端面に前記外面端縁から立ち上がる端面（鍔部１０ａ側面）のそれぞれの清掃体１３がそれぞれ当接し、同時に強く当てて清掃することができる。なお、各清掃体１３の取付面（テーパ筒状部分外面及び鍔部側面）からの突出量は、弾性清掃体１３の縮径によりテーパ面の傾きに応じてテーパ面及び端面に同時に強く当接し得るように適宜に設定する。 Cleaner A ₃ of the embodiment shown in FIG. 4, for example, shown in FIG. 10 (b), In the tool holder T ₃ spindle M of HSK shank, as shown in FIG. 6 (a), similarly to the conventional , cleaned by rotating insert the cleaner a ₃ into the hole H. In the figure, C ₁ is an HSK collet of _{the tool holder T 3} at the tip of the drawer D.
Usually, when cleaning both sides of the fitting hole H having two surfaces, the tapered surface and the end surface, as shown in FIG. 10, by a cleaner having a cleaning surface on the tapered tubular portion and the flange portion 10a, the taper is used. When the cleaning surface of the tubular portion hits the tapered surface of the fitting hole H, a gap is likely to occur between the cleaning surface of the flange portion 10a and the end surface of the fitting hole H. At this time, if the pulling force is due to a mechanical mechanism such as a drawer (for example, 5700 N), the tubular portion corresponding to the tapered surface is deformed or the collar portion is deformed to fit the cleaning surface of the collar portion 10a. It can be applied to the end face of the hole H, but since this type of cleaning is done manually, the cleaner is not easy to deform and is almost impossible. That is, the cleaner main body 10 and the like cannot be deformed by manual force, and the cleaning surface cannot be strongly applied to both sides. However, the cleaning element 13 of the cleaner A ₃ is for a hollow cylindrical shape made of an elastic material, easily obtained much the amount of deformation. Therefore, with respect to both surfaces of the fitting hole H having two surfaces, a tapered surface and an end surface, the tapered surface is a truncated cone-shaped outer surface (tapered surface) of the cleaner main body 10, and the end surface is an end surface rising from the outer edge. Each cleaning body 13 (side surface of the flange portion 10a) comes into contact with each other, and at the same time, it can be strongly applied for cleaning. The amount of protrusion of each cleaning body 13 from the mounting surface (outer surface of the tapered tubular portion and the side surface of the flange portion) strongly abuts on the tapered surface and the end surface at the same time according to the inclination of the tapered surface due to the reduced diameter of the elastic cleaning body 13. Set appropriately to obtain.

また、図５に示すように、有底円筒クリーナ本体１０の内周面及び端面の溝１１に清掃体１３を嵌め込み取り付けしたクリーナＡ_４とすれば、例えば、図１１に示す、ＨＳＫシャンクの工具ホルダＴ_３のシャンク外周面に嵌めて回転することによってその外周面を清掃することができる。この場合も、清掃体１３は弾性材からなる中空の円筒状であるため、その変形量を多くして、テーパ面と端面の２面を有する嵌合穴Ｈのその両面を同時に強く当てて清掃することができる。 Further, as shown in FIG. 5, if the cleaner A ₄ were fitted fit the cleaning element 13 in the groove 11 of the inner peripheral surface and the end surface of the bottomed cylindrical cleaner main body 10, for example, shown in Figure 11, the HSK shank tool it is possible to clean the outer peripheral surface thereof by rotating is fitted to the shank peripheral surface of the holder T _3. Also in this case, since the cleaning body 13 has a hollow cylindrical shape made of an elastic material, the amount of deformation thereof is increased, and both sides of the fitting hole H having two surfaces, a tapered surface and an end surface, are strongly pressed at the same time for cleaning. can do.

さらに、クリーナ本体１０の態様としては、図６に示すように、断面三角形状とし、その各稜の溝１１に清掃体１３を嵌め込み取り付けし、さらに、平面部に起伏自在の起伏片１９を設け、その起伏片１９の外面に清掃体１３を上記溝１１と同一形状（ｔ_１＜ｔ_２）の溝１１を介して設けたものとすることができる。
起伏片１９は、基部１９ａをピン１９ｂを介して径方向に回転自動に取付け、バネ（図示せず）によって径方向外側に揺動可能としている。ピン１９ｂを設けず、起伏片１９自身の弾性によって径方向外側に起立可能とすることもできる。 Further, as an aspect of the cleaner main body 10, as shown in FIG. 6, the cross section is triangular, the cleaning body 13 is fitted and attached to the groove 11 of each ridge thereof, and the undulating piece 19 is provided on the flat surface portion. The cleaning body 13 may be provided on the outer surface of the undulating piece 19 _{via a groove 11 having the same shape (t 1} <t ₂ ) as the groove 11.
The undulating piece 19 is provided with a base portion 19a automatically rotated in the radial direction via a pin 19b, and can swing outward in the radial direction by a spring (not shown). It is also possible to make it possible to stand outward in the radial direction by the elasticity of the undulating piece 19 itself without providing the pin 19b.

この実施形態のクリーナＡ_５は、例えば、図９に示すように、ＨＳＫ規格の工具ホルダＴ_２のシャンク（ＨＳＫシャンク）のようにその穴Ｈの開口部に内方に突出する鍔Ｆ等の凸部がある場合、起伏片１９を鎖線のように倒伏させて穴Ｈ内に差し込み、その後、起伏片１９を起立させて起伏片１９の清掃体１３を穴Ｈの内面に摺動させて清掃する。このクリーナＡ_５は穴Ｈの全内周面を清掃し得る。このとき、前記鍔ＦやクーラントダクトＧの存在によって、穴Ｈ内に指も入らない場合にあっても、起伏片１９の起伏によって、クリーナＡ_５は穴Ｈの全内周面に嵌ってその全内周面を清掃し得る。すなわち、シャンク嵌合穴Ｈの内径が１４ｍｍ程度であっても、起伏片１９の倒伏時の外径が鍔Ｆ内を通り抜ける大きさであれば、その穴Ｈの全内周面を清掃することができる。 Cleaner A ₅ in this embodiment, for example, as shown in FIG. 9, the HSK standard for the tool holder T ₂ shank such flange F protruding inwardly into the opening of the hole H as (HSK shank) If there is a convex portion, the undulating piece 19 is laid down like a chain wire and inserted into the hole H, and then the undulating piece 19 is erected and the cleaning body 13 of the undulating piece 19 is slid on the inner surface of the hole H for cleaning. do. The cleaner A ₅ can clean the entire inner peripheral surface of the hole H. At this time, the presence of the flange F and coolant ducts G, even when the do not fall finger into the hole H, the undulations of the undulating strips 19, cleaner A ₅ are fitted to the entire inner peripheral surface of the hole H thereof The entire inner peripheral surface can be cleaned. That is, even if the inner diameter of the shank fitting hole H is about 14 mm, if the outer diameter of the undulating piece 19 at the time of lodging is large enough to pass through the collar F, the entire inner peripheral surface of the hole H should be cleaned. Can be done.

(D / r = 0.9), r: 2 mm, d / 1.8 (d / r = 0.9) were prototyped, and each groove was shown in FIG. 1 (c). When the cleaning body 13 was fitted into the cleaning body 13 and a cleaning test was performed on the cleaner body 10 having an appropriate thickness (diameter) and an appropriate size of the surface to be cleaned, the cleaning body 13 of the elastic body was firmly formed on the entire inner circumference of the groove 11. Smooth cleaning was possible without sticking and popping out (pulling out).

上記クリーナ本体１０と把持棒２０との連結は、着脱可能な態様であれば、種々の構造を採用することができる。例えば、図７に示すように、把持棒２０のボルト２１をクリーナ本体１０の雌ねじ孔１４ａにねじ込むことによって両者１０、２０を連結する。このとき、クリーナ本体１０と把持棒２０の対向面の少なくとも一方には、放射方向の凹凸条の（スジ目）ローレット加工１５ａをすることが好ましい。このローレット加工１５ａは、他の各実施形態のクリーナ本体１０において、把持部１４の把持棒２０との対向面の少なくとも一方に形成することができる。図７では、把持棒２０の対向面にローレット加工１５ａを施した。
また、図１２に示すように、把持棒２０を筒状とすれば、その筒状内部に予備の棒状清掃体１３や他の各種の部材等を収納することができる。その収納スペース２０ａの開口はねじ込み式やビス止めなどし得る蓋２８で閉じることが好ましい。さらに、把持棒２０や蓋２８には磁石Ｍを内蔵したり、付着させたり、フックを設けたり、チェーン等のストラップ２９を設けたり等して、工作機械周辺やその部品収納スペース、作業スペースにクリーナＡ（Ａ_１〜Ａ_５）を設置し易くする。 Various structures can be adopted for the connection between the cleaner body 10 and the gripping rod 20 as long as they are removable. For example, as shown in FIG. 7, the bolt 21 of the gripping rod 20 is screwed into the female screw hole 14a of the cleaner main body 10 to connect the two 10 and 20. At this time, it is preferable that at least one of the facing surfaces of the cleaner main body 10 and the gripping rod 20 is knurled (streaked) 15a with uneven stripes in the radial direction. This knurling 15a can be formed on at least one of the surfaces of the grip portion 14 facing the grip rod 20 in the cleaner main body 10 of each of the other embodiments. In FIG. 7, knurling 15a was applied to the facing surface of the gripping rod 20.
Further, as shown in FIG. 12, if the gripping rod 20 has a cylindrical shape, a spare rod-shaped cleaning body 13 and various other members can be stored inside the cylindrical shape. The opening of the storage space 20a is preferably closed by a lid 28 that can be screwed or screwed. Further, a magnet M is built in or attached to the gripping rod 20 and the lid 28, a hook is provided, a strap 29 such as a chain is provided, etc. Make it easier to install cleaner A (A _{1 to} A _5).

以上から、この発明は、ＨＳＫ規格の主軸Ｍや工具ホルダシャンクのような複雑な構造を有する穴であっても、弾性体の清掃体１３が溝１１の内周全面にしっかり密着して飛び出すこともなく清掃することができるとともに、清掃体１３を容易に取り付け・取外しを行うことができることが理解できる。
また、清掃体１３を容易に取り付け・取外しを行うことができれば、上記各実施形態において、溝１１の形状は、断面円形に限らず、溝１１の開口１１ａが幅狭となって、溝１１に嵌めた清掃体１３が抜け出なければ（飛び出なければ）、四角等の多角形や蟻溝形などでも良い。また、クリーナ本体１０の形状は、清掃対象物に応じて適宜に変更し得ることは勿論であり、その断面形状は、円形や三角形に限らず、楕円形、四角等の他の多角形とし得る。多角形の場合、正多角形が好ましい。
さらに、清掃体１３は、円筒状の棒材に限らず、上記各実施形態（Ａ_１〜Ａ_５）において、円柱状、角筒状、角柱状等と溝１１に嵌って抜け止めされ得る形状であれば、適宜に選択し得ることは言うまでもない。 From the above, according to the present invention, even in a hole having a complicated structure such as an HSK standard spindle M or a tool holder shank, the elastic cleaning body 13 firmly adheres to the entire inner circumference of the groove 11 and pops out. It can be understood that the cleaning body 13 can be easily attached and detached as well as being able to be cleaned without any problem.
Further, if the cleaning body 13 can be easily attached and detached, in each of the above embodiments, the shape of the groove 11 is not limited to a circular cross section, and the opening 11a of the groove 11 becomes narrower to form the groove 11. As long as the fitted cleaning body 13 does not come out (does not pop out), a polygon such as a square or a dovetail shape may be used. Further, the shape of the cleaner main body 10 can be appropriately changed according to the object to be cleaned, and the cross-sectional shape thereof is not limited to a circle or a triangle, but may be another polygon such as an ellipse or a square. .. In the case of a polygon, a regular polygon is preferable.
