Description

異物除去装置Foreign matter removal device
　本発明は、異物除去装置に関する。 The present invention relates to a foreign matter removing device.
　従来、フィルムを複数枚重ねたワークの端面を、エンドミル等の切削加工することが知られているが、上記フィルムとして粘着剤層付のフィルムを用いた場合、切削加工後に異物（切削屑）が、被切削面に付着するという問題がある。従来は、このような異物が生じた場合、粘着テープ等を用いた手作業にて、異物の除去を行っているが、このような作業は、煩雑であり、効率性に問題がある。また、粘着テープを過剰に要するという点でも、不利である。 Conventionally, it is known that the end face of a work in which a plurality of films are stacked is cut by an end mill or the like, but when a film with an adhesive layer is used as the above film, foreign matter (cut dust) is generated after cutting. However, there is a problem that it adheres to the surface to be cut. Conventionally, when such a foreign substance occurs, the foreign substance is removed manually by using an adhesive tape or the like, but such a work is complicated and there is a problem in efficiency. It is also disadvantageous in that it requires excessive adhesive tape.

　保持ユニット１０は、ワークＷを保持する要素であり、ワークＷの外周面が露出するようにしてワークＷを保持する。ワークＷは、粘着剤層付フィルムを複数枚積層して構成された積層体の外周面を切削して得られる。当該積層体の外周面を切削して得られたワークＷは、その外周面に異物（切削屑）が多く付着している。本発明の異物除去装置１０は、保持ユニット１０に保持されたワークＷの外周面に、異物除去ユニット２０により走行し、任意の適切な粘着力を有する粘着テープ３０の粘着面を当該外周面に押し付けることにより、ワークＷの外周面に付着した異物を除去することができる。本発明の異物除去装置によれば、粘着テープ３０の粘着面の新しい部分（異物除去に供されていない部分が）を、順次、ワークＷの外周面の汚染部分に供給に供給することができ、上記異物を効率よく、自動的に除去することが可能になる。 The holding unit 10 is an element that holds the work W, and holds the work W such that the outer peripheral surface of the work W is exposed. The work W is obtained by cutting the outer peripheral surface of a laminated body formed by laminating a plurality of films with adhesive layers. The work W obtained by cutting the outer peripheral surface of the laminate has a large amount of foreign matter (cutting dust) attached to the outer peripheral surface thereof. In the foreign matter removing device 10 of the present invention, the adhesive surface of the adhesive tape 30 which is run by the foreign matter removing unit 20 and has any appropriate adhesive force on the outer peripheral surface of the work W held by the holding unit 10 is the outer peripheral surface. By pressing, the foreign matter attached to the outer peripheral surface of the work W can be removed. According to the foreign matter removing apparatus of the present invention, a new portion of the adhesive surface of the adhesive tape 30 (the portion that is not used for foreign matter removal) can be sequentially supplied to the contaminated portion of the outer peripheral surface of the work W for supply. The foreign matter can be efficiently and automatically removed.
　１つの実施形態においては、保持ユニット１０は、シャフト１１とシャフト１１の先端に配置された押し付け部１２とを有する２つの保持手段から構成される。ワークＷは、押し付け部１２を対向させるようにして配置された保持手段により押圧されて保持され得る。 In one embodiment, the holding unit 10 is composed of two holding means having a shaft 11 and a pressing portion 12 arranged at the tip of the shaft 11. The work W can be pressed and held by the holding means arranged so that the pressing portions 12 face each other.
　１つの実施形態においては、ワークＷは、当該ワークＷの垂直軸まわりに、回転させられ得る。本実施形態においては、ワークＷの外周全周を効率よく自動的に洗浄することができる。また、粘着テープ３０の粘着面の新しい部分（異物除去に供されていない部分）を、常に、ワークＷの外周面の汚染部分に供給することができる点でも有利である。 In one embodiment, the work W can be rotated about the vertical axis of the work W. In the present embodiment, the entire outer circumference of the work W can be efficiently and automatically cleaned. It is also advantageous in that a new portion of the adhesive surface of the adhesive tape 30 (a portion that has not been used for foreign matter removal) can always be supplied to the contaminated portion of the outer peripheral surface of the work W.
　異物除去ユニット２０は、長尺状の粘着テープ３０を連続的に走行させる機能を有し、繰り出しローラー２１と、巻き取りローラー２２と、当接ローラー２３とを有する。繰り出しローラー２１、巻き取りローラー２２および当接ローラー２３は、ひとつの台座２４上に配置され得る。 The foreign matter removing unit 20 has a function of continuously running the long adhesive tape 30, and has a feeding roller 21, a winding roller 22, and a contact roller 23. The feeding roller 21, the winding roller 22, and the contact roller 23 may be arranged on one pedestal 24.
　繰り出しローラー２１には、金属ローラーや、ゴムローラー、樹脂ローラー等のローラー部材（テープホルダー）を使用することができる。繰り出しローラー２１は、駆動源を有するローラーであってもよく、駆動源を有さないローラーであってもよい。１つの実施形態においては、繰り出しローラー２１は、それ自体では駆動源を持たず、粘着テープ３０の走行に伴い回転するように構成される。繰り出しローラー２１は、パウダーブレーキ等の手段によって、粘着テープ３０にバックテンションを付与するものであってもよい。 As the feeding roller 21, a roller member (tape holder) such as a metal roller, a rubber roller or a resin roller can be used. The delivery roller 21 may be a roller having a drive source or a roller having no drive source. In one embodiment, the feeding roller 21 does not have a drive source by itself, and is configured to rotate as the adhesive tape 30 runs. The feeding roller 21 may apply back tension to the adhesive tape 30 by means of a powder brake or the like.
　巻き取りローラー２２には、金属ローラーや、ゴムローラー、樹脂ローラー等のローラー部材を使用することができる。巻き取りローラー２２は駆動源を有し、回動して粘着テープ３０を巻き取る。１つの実施形態においては、巻き取りローラー２２は、回転するワークＷに押し付けられてつれ回りする当接ローラー２３によって繰り出され走行する粘着テープ３０を、その繰り出された分だけ巻き取る。このようにすれば、粘着テープ３０の使用量を低減することができる。巻き取りローラー２２は、パウダーブレーキ等の手段によって、粘着テープ３０にバックテンションを付与するものであってもよい。 As the winding roller 22, a roller member such as a metal roller, a rubber roller, or a resin roller can be used. The winding roller 22 has a drive source and rotates to wind the adhesive tape 30. In one embodiment, the take-up roller 22 winds up the adhesive tape 30 that is fed and run by the contact roller 23 that is pressed against the rotating work W and wraps around the work W. By doing so, the amount of the adhesive tape 30 used can be reduced. The take-up roller 22 may apply back tension to the adhesive tape 30 by means of a powder brake or the like.
　当接ローラー２３は、繰り出しローラー２１と巻き取りローラー２２との間（粘着テープ３０の走行経路途中）に配置される。当接ローラー２３は、当接ローラー２３により粘着テープ３０の走行方向が変化するように配置され得る。また、当接ローラー２３は、粘着テープ３０の抱き角が、４５°～２００°となるように配置されることが好ましく、９０°～１８０°となるように配置されることがより好ましい。 The contact roller 23 is arranged between the feeding roller 21 and the take-up roller 22 (on the way of travel of the adhesive tape 30). The contact roller 23 may be arranged such that the traveling direction of the adhesive tape 30 is changed by the contact roller 23. Further, the contact roller 23 is preferably arranged such that the wrapping angle of the adhesive tape 30 is 45° to 200°, and more preferably 90° to 180°.
　当接ローラー２３は、前後動可能に構成され得、異物除去動作前および異物除去動作後には、ワークＷから離間して位置し得、また、異物除去動作の際にはワークＷの外周面に当接するように移動することができる。また、当接ローラー２３は所定の駆動手段により付勢されて、ワークＷの形状および回転に追従して、当接ローラーが前後動可能なように構成される。このようにすれば、異物除去の際、ワークＷの回転最外軌跡に対応して、当接ローラーを位置させることができ、異物除去動作中常時、当接ローラー２３により粘着テープ３０をワークＷに押し付けることができる。当接ローラー２３は、駆動源を有さず、回転するワークＷに押し付けられてつれ回りするように構成され得る。当接ローラー２３は回転軸がワークＷの積層方向に延びるように配置され得る。 The contact roller 23 can be configured to be movable back and forth, can be positioned apart from the work W before and after the foreign matter removing operation, and can be positioned on the outer peripheral surface of the work W during the foreign matter removing operation. It can move to abut. Further, the contact roller 23 is biased by a predetermined driving means so that the contact roller can be moved back and forth in accordance with the shape and rotation of the work W. By doing so, the contact roller can be positioned corresponding to the outermost rotation locus of the work W when removing the foreign matter, and the contact roller 23 keeps the adhesive tape 30 attached to the work W during the foreign matter removing operation. Can be pressed against. The contact roller 23 does not have a drive source, and may be configured to be pressed against the rotating work W and rotate around. The contact roller 23 may be arranged such that the rotation axis extends in the stacking direction of the works W.
　当接ローラー２３の前後動は、任意の適切な手段で行うことができる。当接ローラー２３の前後動は、例えば、シリンダー（エアシリンダー、油圧シリンダー等）、バネ、モーター等の駆動手段を用いて行うことができる。好ましくは、繰り出しローラー２１、巻き取りローラー２２および当接ローラー２３をひとつの台座２４上に配置して、当該台座２４を前後動させることにより、当接ローラー２３を前後動させる。 The back-and-forth movement of the contact roller 23 can be performed by any appropriate means. The back-and-forth movement of the contact roller 23 can be performed by using a driving means such as a cylinder (air cylinder, hydraulic cylinder, etc.), a spring, a motor, or the like. Preferably, the feeding roller 21, the winding roller 22, and the contact roller 23 are arranged on one pedestal 24, and the pedestal 24 is moved back and forth, whereby the contact roller 23 is moved back and forth.
　１つの実施形態においては、図２に示すように、シリンダー２５とバネ２６とを組み合わせて、当接ローラー２３（または、ローラー２３が配置された台座２４）を前後動させる。１つの実施形態においては、バネ２６が、当接ローラー２３の前方移動（ワークＷに向かう移動）、および当接ローラー２３のワークＷへの押し付けに用いられ、シリンダー２５（好ましくはエアシリンダー）が当接ローラー２３の後方移動に用いられる。当接ローラー２３のワークＷへの押し付けに、バネ２６を用いてもよい。 In one embodiment, as shown in FIG. 2, a cylinder 25 and a spring 26 are combined to move the contact roller 23 (or the pedestal 24 on which the roller 23 is arranged) back and forth. In one embodiment, the spring 26 is used for moving the contact roller 23 forward (moving toward the work W) and pressing the contact roller 23 against the work W, and the cylinder 25 (preferably an air cylinder) is used. It is used for rearward movement of the contact roller 23. The spring 26 may be used to press the contact roller 23 against the work W.
　１つの実施形態においては、当接ローラー２３は、表面に弾性層を有する弾性ローラーである。弾性ローラーを用いれば、当接ローラー２３をワークＷに押し付ける際にローラー表面が変形して、ワーク外周面の微小な凹凸に当接ローラー２３を良好に追従させることができ、また、当接ローラー２３を傾いたワークに追従させることもできる。その結果、当接ローラー２３（実質的には粘着テープ３０）とワークＷとの間の隙間発生を防止し得る。 In one embodiment, the contact roller 23 is an elastic roller having an elastic layer on its surface. If an elastic roller is used, the roller surface is deformed when the contact roller 23 is pressed against the work W, and the contact roller 23 can be made to follow fine irregularities on the outer peripheral surface of the work well. 23 can be made to follow the inclined work. As a result, it is possible to prevent the occurrence of a gap between the contact roller 23 (substantially the adhesive tape 30) and the work W.
　当接ローラー２３の押し付け圧は、好ましくは０．２ＭＰａ～０．５ＭＰａであり、より好ましくは０．３ＭＰａ～０．４ＭＰａである。このような押し付け圧で、当接ローラー２３をワークＷに押し付け、当接ローラー２３とワークＷとの間に粘着テープ３０を走行させることにより、ワークＷの外周に付着した異物をより良好に除去することができ、また、外周面の品質を良好に維持することができる。 The pressing pressure of the contact roller 23 is preferably 0.2 MPa to 0.5 MPa, more preferably 0.3 MPa to 0.4 MPa. With such a pressing pressure, the contact roller 23 is pressed against the work W, and the adhesive tape 30 is run between the contact roller 23 and the work W, so that foreign matter adhering to the outer periphery of the work W is better removed. In addition, the quality of the outer peripheral surface can be favorably maintained.
　上記弾性層の硬度（ＪＩＳ　Ａ）は、好ましくは６０°未満であり、より好ましくは５０°未満であり、さらに好ましくは２０°～４０°であり、特に好ましくは２０°～４０°である。このような範囲であれば、ワークＷの外周に付着した異物をより良好に除去することができる。 The hardness (JIS A) of the elastic layer is preferably less than 60°, more preferably less than 50°, even more preferably 20° to 40°, and particularly preferably 20° to 40°. With such a range, foreign matter attached to the outer periphery of the work W can be removed more favorably.
　上記弾性層は、任意の適切な材料により形成され得る。弾性層を形成する材料としては、例えば、ブチルゴム、フッ素系ゴム、アクリルゴム、エチレンプロピレンゴム（ＥＰＤＭ）、ニトリルブタジエンゴム（ＮＢＲ）、アクリロニトリルブタジエンスチレンゴム、天然ゴム、イソプレンゴム、スチレン－ブタジエンゴム、ブタジエンゴム、エチレン－プロピレンゴム、エチレン－プロピレンターポリマー、クロロプレンゴム、クロロスルホン化ポリエチレン、塩素化ポリエチレン、ウレタンゴム、シンジオタクチック１，２－ポリブタジエン、エピクロロヒドリン系ゴム、シリコーンゴム、フッ素ゴム、多硫化ゴム、ポリノルボルネンゴム、水素化ニトリルゴム、熱可塑性エラストマー（例えばポリスチレン系、ポリオレフィン系、ポリ塩化ビニル系、ポリウレタン系、ポリアミド系、ポリウレア、ポリエステル系、フッ素樹脂系）、およびそれらの混合物等が挙げられる。 The elastic layer may be formed of any appropriate material. Examples of the material forming the elastic layer include butyl rubber, fluorine rubber, acrylic rubber, ethylene propylene rubber (EPDM), nitrile butadiene rubber (NBR), acrylonitrile butadiene styrene rubber, natural rubber, isoprene rubber, styrene-butadiene rubber, Butadiene rubber, ethylene-propylene rubber, ethylene-propylene terpolymer, chloroprene rubber, chlorosulfonated polyethylene, chlorinated polyethylene, urethane rubber, syndiotactic 1,2-polybutadiene, epichlorohydrin rubber, silicone rubber, fluororubber , Polysulfide rubber, polynorbornene rubber, hydrogenated nitrile rubber, thermoplastic elastomers (eg polystyrene, polyolefin, polyvinyl chloride, polyurethane, polyamide, polyurea, polyester, fluororesin), and mixtures thereof. Etc.
　上記弾性層の厚みは、好ましくは４ｍｍ以上であり、より好ましくは５ｍｍ以上であり、さらに好ましくは７ｍｍ以上である。このような範囲であれば、ワークＷの外周に付着した異物をより良好に除去することができる。 The thickness of the elastic layer is preferably 4 mm or more, more preferably 5 mm or more, and further preferably 7 mm or more. With such a range, foreign matter attached to the outer periphery of the work W can be removed more favorably.
　当接ローラー２３の外径は、好ましくは１０ｍｍ～１００ｍｍであり、さらに好ましくは２０ｍｍ～６０ｍｍである。当接ローラー２３の幅は、ワークＷの厚み以上であることが好ましい。 The outer diameter of the contact roller 23 is preferably 10 mm to 100 mm, more preferably 20 mm to 60 mm. The width of the contact roller 23 is preferably equal to or larger than the thickness of the work W.
Ｂ．異物除去方法
　本発明の異物除去方法は、上記異物除去装置を用いて、所定のワークの外周面に付着した異物を除去する方法である。 B. Foreign Material Removal Method The foreign material removal method of the present invention is a method of removing foreign material attached to the outer peripheral surface of a predetermined work by using the above foreign material removal device.
　本発明の異物除去方法は、上記ワークを異物除去装置の保持ユニットにセットすること、および、上記異物除去ユニットを走行する粘着テープを、該ワークの外周面に押し付けながら、該ワークの外周面に付着した異物を除去することを含む。 The foreign matter removing method of the present invention comprises setting the work on a holding unit of the foreign matter removing device, and pressing an adhesive tape running on the foreign matter removing unit against the outer circumferential surface of the work while pressing the outer circumferential surface of the work. This includes removing adhered foreign substances.
　上記ワークは、粘着剤層付フィルムを複数枚積層して構成された積層体の外周面を切削して得られたワークである。粘着剤層付フィルムとしては、任意の適切なフィルムが用いられ得る。例えば、粘着剤層付樹脂フィルム（例えば、光学フィルム）、粘着剤層付ガラスフィルム、これらの複合フィルム等が挙げられる。上記積層体は、ワーク形成に際し、代表的には任意の適切な形状に切断されている。具体的には、光学積層体は矩形形状に切断されていてもよく、矩形形状に類似する形状に切断されていてもよく、目的に応じた適切な形状（例えば、円形）に切断されていてもよい。 The above work is a work obtained by cutting the outer peripheral surface of a laminate formed by laminating a plurality of films with an adhesive layer. Any appropriate film can be used as the film with the pressure-sensitive adhesive layer. For example, a resin film with a pressure-sensitive adhesive layer (for example, an optical film), a glass film with a pressure-sensitive adhesive layer, a composite film of these and the like can be mentioned. The above-mentioned laminated body is typically cut into any appropriate shape when forming a work. Specifically, the optical laminated body may be cut into a rectangular shape, may be cut into a shape similar to the rectangular shape, or may be cut into an appropriate shape (for example, a circle) according to the purpose. Good.
　ワークの外周は、任意の適切な切削手段により切削されている。切削は、切削手段の切削刃を上記積層体の外周面に当接させることにより行われ得る。切削は、上記積層体の外周面の全周にわたって行ってもよく、所定の位置のみに行ってもよい。切削手段としては、例えば、エンドミルが挙げられる。１つの実施形態においては、上記ワークは、粘着剤層付フィルムを複数枚積層して構成された積層体を垂直軸まわりに回転させながら、切削手段を該積層体の外周面に当接させることにより得られたワークである。１つの実施形態においては、このような切削が、上記保持ユニットに上記積層体を保持して行われる。切削後に得られたワークは、当該保持ユニットに保持されたまま、異物除去装置に投入されて、異物除去工程に供され得る。 The outer periphery of the work is cut by any appropriate cutting means. The cutting can be performed by bringing the cutting blade of the cutting means into contact with the outer peripheral surface of the laminate. The cutting may be performed over the entire circumference of the outer peripheral surface of the laminate, or may be performed only at a predetermined position. An example of the cutting means is an end mill. In one embodiment, the work is such that the cutting means is brought into contact with the outer peripheral surface of the laminated body while rotating the laminated body constituted by laminating a plurality of films with adhesive layers around a vertical axis. It is the work obtained by. In one embodiment, such cutting is performed by holding the laminated body in the holding unit. The work obtained after cutting can be put into the foreign matter removing device while being held by the holding unit, and can be subjected to the foreign matter removing step.
　上記切削時のワークの回転速度（ｒｐｓ）は、例えば、０．０２ｒｐｓ～０．０４ｒｐｓである。 The rotation speed (rps) of the work during the cutting is, for example, 0.02 rps to 0.04 rps.
　１つの実施形態においては、上記ワークを保持ユニットにセットした後、上記のごとく、ワークを垂直軸まわりに回転させながら、前記異物除去ユニットを走行する粘着テープを、該ワークの外周面に押し付ける。代表的には、異物除去ユニットの当接ローラーを前方移動させて、当接ローラーを当該ワークに押し付ける。このとき、異物除去ユニットにおいては、異物除去ユニットが備える繰り出しローラーから巻き取りローラーにかけて、粘着テープがセットされており、当接ローラーの前方移動により、異物除去ユニットを走行する粘着テープがワークの外周面に押し付けられるようになる。これにより、ワークに接触した粘着テープの粘着面によって、ワークの外周面に付着した異物を除去することができる。１つの実施形態においては、粘着テープは、ワークの回転に合わせてつれ回りする当接ローラーにより走行する。 In one embodiment, after the work is set on the holding unit, the adhesive tape running on the foreign matter removing unit is pressed against the outer peripheral surface of the work while rotating the work around the vertical axis as described above. Typically, the contact roller of the foreign matter removing unit is moved forward to press the contact roller against the work. At this time, in the foreign matter removing unit, the adhesive tape is set from the feeding roller provided in the foreign matter removing unit to the take-up roller, and the forward movement of the contact roller causes the adhesive tape running in the foreign matter removing unit to move to the outer periphery of the work. It will be pressed against the surface. Thus, the adhesive surface of the adhesive tape that is in contact with the work can remove foreign matter attached to the outer peripheral surface of the work. In one embodiment, the adhesive tape is driven by a contact roller that rotates along with the rotation of the work.
　１つの実施形態においては、上記ワークの回転速度は、外周面を切削する際の積層体の回転速度よりも速い。ワークの回転速度（ｒｐｓ）は、例えば、０．０５ｒｐｓ～０．５ｒｐｓである。 In one embodiment, the rotation speed of the work is higher than the rotation speed of the laminate when cutting the outer peripheral surface. The rotation speed (rps) of the work is, for example, 0.05 rps to 0.5 rps.
　ワークの回転速度は、一定でなくてもよい。例えば、矩形状のワークを異物除去に供する場合、当該ワークの角部が粘着テープに接触する前後で、ワークの回転速度を遅くしてもよい。このようにすれば、ワークの回転最外軌跡の急な変化に、当接ローラーを追従させることが容易となる。特に、当接ローラーが急に前進する際、例えば、粘着テープの接触位置が短辺から長辺に切り替わる角部（異物除去ユニットが前進しながら角度が急激に変わる様に清掃する場合）において、ワークの回転速度を遅くすることが好ましい。１つの実施形態においては、ワークの角部が粘着テープに接触する際のワークの回転速度が、ワークの直線部分が粘着テープに接触する際のワークの回転速度に対して、５０％～９０％に設定される。 -The rotation speed of the work does not have to be constant. For example, when a rectangular work is used for removing foreign matter, the rotation speed of the work may be slowed before and after the corner of the work comes into contact with the adhesive tape. With this configuration, it becomes easy for the contact roller to follow a sudden change in the rotation outermost locus of the work. In particular, when the contact roller suddenly advances, for example, at the corner where the contact position of the adhesive tape switches from the short side to the long side (when cleaning the foreign matter removing unit so that the angle rapidly changes while advancing), It is preferable to reduce the rotation speed of the work. In one embodiment, the rotation speed of the work when the corner portion of the work contacts the adhesive tape is 50% to 90% with respect to the rotation speed of the work when the linear portion of the work contacts the adhesive tape. Is set to.
　上記当接ローラーのワークに対する押し付け圧は、好ましくは０．２ＭＰａ～０．５ＭＰａであり、より好ましくは０．３ＭＰａ～０．４ＭＰａである。このような押し付け圧で、当接ローラーをワークに押し付け、当接ローラーとワークとの間に粘着テープを走行させることにより、ワークの外周に付着した異物をより良好に除去することができ、また、ワークを構成するフィルムの層間剥離、粘着剤層の欠け等を防止して、外周面の品質を良好に維持することができる。 The pressing pressure of the contact roller against the work is preferably 0.2 MPa to 0.5 MPa, more preferably 0.3 MPa to 0.4 MPa. With such a pressing pressure, the contact roller is pressed against the work, and by running the adhesive tape between the contact roller and the work, it is possible to better remove foreign matter attached to the outer periphery of the work, and It is possible to prevent delamination of the film constituting the work, chipping of the pressure-sensitive adhesive layer, and the like, and maintain good quality of the outer peripheral surface.
　１つの実施形態においては、上記ワークの回転方向が、外周面を切削する際の積層体の回転方向とは、逆方向である、このようにすれば、より良好にワーク外周に付着した異物を除去することができる。 In one embodiment, the rotation direction of the work is opposite to the rotation direction of the laminated body when cutting the outer peripheral surface. By doing so, foreign matter adhering to the work outer periphery can be better removed. Can be removed.
　上記の異物除去方法において、異物除去動作開始から終了までのワークの回転数は、好ましくは１回転～１０回転であり、より好ましくは１回転～５回転であり、さらに好ましくは１回転である。本発明によれば、短時間でワーク外周の異物を除去することができる。ワークの端面（外周）を１周清掃してもよいし、２周清掃してもよいし、３周以上清掃してもよい。 In the above method of removing foreign matter, the number of rotations of the work from the start to the end of the foreign matter removal operation is preferably 1 to 10 rotations, more preferably 1 to 5 rotations, and further preferably 1 rotation. According to the present invention, it is possible to remove foreign matter on the outer circumference of a work in a short time. The end surface (outer circumference) of the work may be cleaned once, twice or three or more times.
　以下、実施例により本発明を具体的に説明するが、本発明はこれらの実施例には限定されない。 Hereinafter, the present invention will be specifically described by way of examples, but the present invention is not limited to these examples.
