Description

本発明は、シート状や板状の被塗布物（基材）の表面に塗布液を塗布する塗布工具に関するものである。   The present invention relates to a coating tool for coating a coating liquid on the surface of a sheet-like or plate-like article (base material).

このような塗布工具としては、複数の横長のヘッド部材が、これらのヘッド部材の長手方向に延びる長側面を互いに対向させて取り付けられることにより工具本体が構成され、上記長側面に形成された長手方向に延びるマニホールドから工具本体の先端部に開口する溝を通して塗布液を吐出し、上記長手方向に直交する方向に工具本体と相対的に移動する被塗布物に塗布液を塗布して塗布膜を形成するものが知られている。工具本体の先端部にはヘッド部材の先端面から突出するリップ部が設けられ、このリップ部の内側面に上記溝の先端の内壁面が形成される。   As such an application tool, a plurality of horizontally long head members are attached with long side surfaces extending in the longitudinal direction of these head members facing each other to form a tool body, and the long side formed on the long side surface is formed. The coating liquid is discharged from the manifold extending in the direction through the groove opened at the tip of the tool body, and the coating liquid is applied to the coating object that moves relative to the tool body in the direction perpendicular to the longitudinal direction. What is formed is known. A lip portion protruding from the tip surface of the head member is provided at the tip portion of the tool body, and an inner wall surface at the tip of the groove is formed on the inner surface of the lip portion.

このような塗布工具において、例えば特許文献１には、リップ部から離れた位置で上記溝を形成するヘッド部材の側面の一部を弾性変形させて膨らませたり凹ませたりすることにより、溝を流れる塗布液の流量を調整するようにしたものが記載されている。また、特許文献２には、やはりリップ部から離れた位置で上記溝に臨ませて配設され、溝の長手方向に分割した複数個の分割バーと、分割バーごとに設けた進退調節具とを備え、各進退調節具で各分割バーを進退させることで溝の隙間量を調節するようにしたものが記載されている。   In such a coating tool, for example, Patent Document 1 discloses that a part of the side surface of the head member forming the groove is elastically deformed at a position away from the lip portion to be expanded or recessed to flow through the groove. The one in which the flow rate of the coating solution is adjusted is described. Patent Document 2 also discloses a plurality of divided bars which are arranged facing the groove at positions away from the lip portion and divided in the longitudinal direction of the groove, and an advance / retreat adjuster provided for each divided bar. , And the amount of groove clearance is adjusted by advancing and retracting each divided bar with each advance / retreat adjuster.

さらに、特許文献３、４には、リップ部近傍において切込部を長手方向に延設したヘッド部材と、この切込部を形成する両側部に各端部を嵌合した調節具の複数組とを備え、各調節具の両端部間に引張力または圧縮力を発生させることによりリップ部の変形量を調節して、溝の開口幅やリップ部と被塗布物との間隔を調整するようにしたものが記載されている。   Further, in Patent Documents 3 and 4, a plurality of sets of a head member in which a cut portion is extended in the longitudinal direction in the vicinity of the lip portion and an adjustment tool in which each end portion is fitted to both side portions forming the cut portion. The amount of deformation of the lip portion is adjusted by generating a tensile force or a compressive force between both end portions of each adjustment tool, so that the opening width of the groove and the gap between the lip portion and the object to be coated are adjusted. What is made is described.

特許第５７３２７３６号公報Japanese Patent No. 5732736 特開２００７−０４４６４３号公報JP 2007-044643 A 特許第２７８００１６号公報Japanese Patent No. 2780016 特開平６−０２３８２１号公報JP-A-6-023821

しかしながら、特許文献１、２に記載された塗布工具のように、リップ部から離れた位置で溝を形成するヘッド部材の側面を弾性変形させたり溝内に分割バーを進退させたりして塗布液の流量や溝の隙間量を調整するようにしたものでは、調整位置からリップ部の先端までの距離が長くなり、調整位置では流量が調整されてもリップ部の先端から吐出するまでの間に戻ってしまうため、調整位置における調整量を大きくしなければ実際に塗布される塗布液の流量を調整することはできない。また、特許文献２に記載されたように複数個の分割バーと分割バーごとに設けた進退調節具とを要するものでは、部品数が多くなって管理が煩雑となる。   However, like the coating tools described in Patent Documents 1 and 2, the coating liquid is formed by elastically deforming the side surface of the head member that forms the groove at a position away from the lip portion, or by moving the dividing bar back and forth in the groove. If the flow rate and groove clearance are adjusted, the distance from the adjustment position to the tip of the lip will be longer, and even if the flow rate is adjusted at the adjustment position, Therefore, the flow rate of the coating liquid to be actually applied cannot be adjusted unless the adjustment amount at the adjustment position is increased. Further, as described in Patent Document 2, in the case of requiring a plurality of division bars and an advance / retreat adjustment tool provided for each division bar, the number of parts increases and management becomes complicated.

一方、図６ないし図９は、特許文献３、４に記載された塗布工具をモデル化したものであり、これらの図において符号１は工具本体、符号２、３はヘッド部材、符号４はマニホールド、符号５は溝、符号６はリップ部、符号７は切込部、符号８は調整具（微調整機構）としての差動ネジ、符号９は溝５以外の部分でヘッド部材２、３の互いに対向する側面２Ａ、３Ａ間に介装されるシムであって、ヘッド部材２、３およびシム９は複数の取付ボルト１０によって締結されて工具本体１に組み立てられている。   On the other hand, FIGS. 6 to 9 are models of the coating tool described in Patent Documents 3 and 4. In these drawings, reference numeral 1 is a tool body, reference numerals 2 and 3 are head members, and reference numeral 4 is a manifold. Reference numeral 5 denotes a groove, reference numeral 6 denotes a lip portion, reference numeral 7 denotes a cut portion, reference numeral 8 denotes a differential screw as an adjustment tool (fine adjustment mechanism), and reference numeral 9 denotes a portion other than the groove 5 of the head members 2 and 3. The head members 2, 3 and the shim 9 are fastened by a plurality of mounting bolts 10 and assembled to the tool body 1.

ところが、このような特許文献３、４に基づく塗布工具において、例えば溝５の開口幅を狭くするように調整を行うと、図９に示すように切込部７と側面２Ａとの間の部分を中心としてヘッド部材２の切込部７よりも先端側（図７ないし図９において上側）の部分が大きく傾いてしまうため、このヘッド部材２側のリップ部６の先端面６Ａも傾いて、溝５の先端のリップ部６の刃先６Ｂとなるリップ部６の先端面６Ａと内側面６Ｃとの交差稜線の位置が後退してしまい、開口幅の調整量が大きくなるに従って溝５の深さ方向（図８および図９において上下方向）における刃先６Ｂの高さの変化量が大きくなってしまう。このため、上記溝５の深さ方向における刃先６Ｂの真直度が損なわれて均一な塗布膜を形成することが困難となるおそれがある。   However, in such an application tool based on Patent Documents 3 and 4, for example, when adjustment is performed so that the opening width of the groove 5 is narrowed, a portion between the cut portion 7 and the side surface 2A as shown in FIG. Since the portion on the tip side (the upper side in FIGS. 7 to 9) of the head member 2 is largely inclined with respect to the notch portion 7 of the head member 2, the tip surface 6A of the lip portion 6 on the head member 2 side is also tilted. The depth of the groove 5 increases as the position of the intersection ridge line between the tip surface 6A and the inner surface 6C of the lip 6 that becomes the cutting edge 6B of the lip 6 at the tip of the groove 5 recedes, and the adjustment amount of the opening width increases. The amount of change in the height of the cutting edge 6B in the direction (vertical direction in FIGS. 8 and 9) becomes large. For this reason, the straightness of the cutting edge 6B in the depth direction of the groove 5 may be impaired, and it may be difficult to form a uniform coating film.

また、このように溝５の開口幅を狭くするように調整を行った場合にリップ部６の刃先６Ｂが後退してしまって刃先６Ｂの高さの変化量が大きくなることにより、実際に被塗布物に塗布される塗布膜の厚さ（塗工厚み）の変化量は、溝幅の変化量に対して小さなものとなる。すなわち、上記特許文献３、４に基づく塗布工具では、溝幅の変化量に対する塗工厚みの変化量が鈍感で、実際の塗工厚みを調整するには溝幅をより大きく変化させなければならず、塗工厚みの調整が制限されざるを得ない。   In addition, when the adjustment is performed so that the opening width of the groove 5 is narrowed in this way, the cutting edge 6B of the lip portion 6 is retracted, and the amount of change in the height of the cutting edge 6B is increased. The amount of change in the thickness (coating thickness) of the coating film applied to the application is small relative to the amount of change in the groove width. That is, in the coating tool based on the said patent documents 3 and 4, the variation | change_quantity of the coating thickness with respect to the variation | change_quantity of a groove width is insensitive, and in order to adjust actual coating thickness, you have to change a groove width more largely. Therefore, the adjustment of the coating thickness must be limited.

本発明は、このような背景の下になされたもので、溝の開口幅を調整する際にリップ部の刃先が溝の深さ方向に後退することがなく、この深さ方向における刃先の真直度を維持して均一な塗布膜を形成することが可能であるとともに、溝幅変化量に対して塗工厚みの変化量を確実かつ大きく調整することができ、さらに必要以上に部品数が多くなることもない塗布工具を提供することを目的としている。   The present invention has been made under such a background, and when adjusting the opening width of the groove, the blade edge of the lip portion does not retract in the depth direction of the groove, and the straightness of the blade edge in this depth direction is achieved. It is possible to form a uniform coating film while maintaining the degree, and the amount of change in coating thickness can be adjusted reliably and largely with respect to the amount of change in groove width, and there are more parts than necessary. The object is to provide a coating tool that never happens.

上記課題を解決して、このような目的を達成するために、本発明は、複数の横長のヘッド部材が、このヘッド部材の長手方向に延びる互いの側面を対向させて取り付けられることにより工具本体が構成され、上記側面に形成された上記長手方向に延びるマニホールドから上記工具本体の先端部に開口する溝を通して塗布液を吐出して被塗布物に塗布する塗布工具であって、上記ヘッド部材における上記側面の先端部には、上記溝の深さ方向に垂直な底面と、この底面から上記ヘッド部材の先端側に向かう壁面とを有する凹部が上記長手方向に延びるように形成されていて、この凹部には、上記溝の先端部にリップ部を有するとともに上記底面に密着する着座面を備えたブロックが上記長手方向に延びるように配設されて取り付けられており、さらに上記ヘッド部材には、このブロックを上記溝の幅方向に押圧して弾性変形させる微調整機構が備えられていることを特徴とする。   In order to solve the above-mentioned problems and achieve such an object, the present invention provides a tool main body in which a plurality of horizontally long head members are mounted with their side surfaces extending in the longitudinal direction facing each other. Is a coating tool that discharges a coating liquid from a manifold that is formed on the side surface and extends in the longitudinal direction through a groove that opens to the tip of the tool body, and coats an object to be coated. A concave portion having a bottom surface perpendicular to the depth direction of the groove and a wall surface extending from the bottom surface toward the distal end side of the head member is formed at the distal end portion of the side surface so as to extend in the longitudinal direction. A block having a lip portion at the tip of the groove and a seating surface that is in close contact with the bottom surface is disposed and attached to the recess so as to extend in the longitudinal direction. The aforementioned head member in al, this block, characterized in that the fine adjustment mechanism to elastically deform by pressing in the width direction of the groove is provided.

このように構成された塗布工具では、溝の先端部にリップ部を有するブロックが、その着座面を溝の深さ方向に垂直な凹部の底面に密着させて取り付けられており、このブロックが微調整機構によって溝の幅方向に押圧されて弾性変形させられるので、ブロックおよびリップ部が大きく傾いて溝の深さ方向に変位することはなく、溝の幅だけが微調整される。このため、溝の深さ方向における刃先の真直度を維持して均一な塗布膜を形成することができるとともに、溝幅の変化量をそのまま確実に塗工厚みの変化量に反映させることが可能となる。しかも、ブロックは１つのヘッド部材に対して１つでよいので、部品数が必要以上に多くなることもない。   In the coating tool configured in this manner, a block having a lip portion at the tip of the groove is attached with its seating surface in close contact with the bottom surface of the recess perpendicular to the depth direction of the groove. Since the adjusting mechanism is pressed in the width direction of the groove to be elastically deformed, the block and the lip portion are not greatly inclined and displaced in the depth direction of the groove, and only the width of the groove is finely adjusted. Therefore, it is possible to form a uniform coating film while maintaining the straightness of the cutting edge in the depth direction of the groove, and it is possible to reliably reflect the change amount of the groove width to the change amount of the coating thickness as it is. It becomes. In addition, since one block is sufficient for one head member, the number of parts does not increase more than necessary.

ここで、上記ブロックは、引き込みボルトによって上記凹部の底面と壁面とが交差する隅角部に向けて上記底面と壁面とに斜めに交差する方向に引き込まれて上記凹部に取り付けられることにより、ブロックの取付安定性を確保して刃先の真直度を一層確実に維持することが可能となるとともに、微調整機構による溝幅の調整精度も向上させることができる。   Here, the block is pulled by a pull-in bolt toward a corner portion where the bottom surface and the wall surface of the recess intersect, and is attached to the recess by being pulled in a direction obliquely intersecting the bottom surface and the wall surface. In addition, it is possible to maintain the straightness of the cutting edge more reliably by securing the mounting stability, and it is possible to improve the adjustment accuracy of the groove width by the fine adjustment mechanism.

また、上記微調整機構は、内外周にピッチの異なるネジ部を有し、上記凹部の底面に平行に延びて上記溝を形成する側面とは反対側の上記ヘッド部材の側面から上記凹部の壁面に貫通するネジ孔にねじ込まれた円筒状ネジと、この円筒状ネジの内周の上記ネジ部にねじ込まれて上記壁面に対向する上記ブロックの側面に当接またはねじ込まれる円柱状ネジとを備えた差動ネジとすることにより、円筒状ネジの内外周のネジ部のピッチの差に応じてより細かい溝幅の微調整を行うことが可能となる。   In addition, the fine adjustment mechanism has screw portions with different pitches on the inner and outer circumferences, and extends in parallel to the bottom surface of the recess to form the groove from the side surface of the head member opposite to the side surface forming the groove. A cylindrical screw that is screwed into a screw hole that penetrates the cylindrical screw, and a cylindrical screw that is screwed into the screw portion on the inner periphery of the cylindrical screw and is in contact with or screwed into the side surface of the block facing the wall surface. By using the differential screw, it is possible to finely adjust the groove width more finely according to the difference in pitch between the screw portions on the inner and outer periphery of the cylindrical screw.

以上説明したように、本発明によれば、必要以上に部品数を増やすことなく、溝幅を調整した際に均一な塗布膜を形成することが可能となるとともに、溝幅の変化量に確実に塗工量の変化量を反映させることが可能となる。   As described above, according to the present invention, it is possible to form a uniform coating film when adjusting the groove width without increasing the number of parts more than necessary, and to ensure the amount of change in the groove width. It is possible to reflect the amount of change in the coating amount.

図１ないし図５は、本発明の一実施形態を示すものである。本実施形態の塗布工具において、工具本体１１は、鋼材等の金属材料によって形成された断面略方形で同形同大の横長ブロック状の複数（本実施形態では２つ）のヘッド部材１２、１３が、互いの１つの長側面１２Ａ、１３Ａを対向させるとともに、これらの長側面１２Ａ、１３Ａの間に同じく鋼材等の金属材料よりなる板状のシム１４を介装させ、取付ボルト１５によって締結されることにより構成されている。   1 to 5 show an embodiment of the present invention. In the application tool of the present embodiment, the tool body 11 is composed of a plurality of (two in the present embodiment) head members 12 and 13 in the form of horizontally-blocked blocks having a substantially rectangular cross section and the same shape formed of a metal material such as steel. However, the long side surfaces 12A and 13A are opposed to each other, and a plate-like shim 14 made of a metal material such as a steel material is interposed between the long side surfaces 12A and 13A and fastened by a mounting bolt 15. It is constituted by.

このうち、本実施形態では図３ないし図５における左側の一方のヘッド部材１２に、上記長手方向に直交する断面において半円形をなして長側面１２Ａに開口する溝状のマニホールド１６が、該長手方向に延びるとともにヘッド部材１２の長手方向の両端面には開口しないように形成されており、このマニホールド１６には図示されない塗布液の供給路が接続されている。また、シム１４は、このマニホールド１６の部分からヘッド部材１２、１３の先端面１２Ｂ、１３Ｂにかけて切り欠かれており、この切り欠かれた部分が工具本体１１において塗布液が流れる溝１７とされる。   Of these, in the present embodiment, a groove-like manifold 16 having a semicircular shape in a cross section perpendicular to the longitudinal direction and opening to the long side surface 12A is formed on the left head member 12 in FIGS. The head member 12 is formed so as not to open at both end surfaces in the longitudinal direction of the head member 12, and a coating liquid supply path (not shown) is connected to the manifold 16. The shim 14 is notched from the manifold 16 portion to the front end surfaces 12B and 13B of the head members 12 and 13, and the notched portion serves as a groove 17 through which the coating liquid flows in the tool body 11. .

さらに、この一方のヘッド部材１２の長側面１２Ａの先端部には、上記溝１７の深さ方向（図２ないし図５において上下方向）に延びる断面長方形状の凹所１２Ｃがヘッド部材１２の長手方向全長に亙って形成されている。この凹所１２Ｃには、ヘッド部材１２よりも硬度の高い超硬合金等の硬質材料よりなる断面長方形状のリップ部材１８がロウ付けやボルト止めによって取り付けられている。   Further, a recess 12C having a rectangular cross section extending in the depth direction (vertical direction in FIGS. 2 to 5) of the groove 17 is formed at the distal end of the long side surface 12A of the one head member 12. It is formed over the entire length. A lip member 18 having a rectangular cross section made of a hard material such as cemented carbide having a hardness higher than that of the head member 12 is attached to the recess 12C by brazing or bolting.

このリップ部材１８の溝１７側を向く内側面１８Ａはヘッド部材１２の長側面１２Ａと面一となるように研磨されて溝１７の先端側の一方の内壁面とされるとともに、リップ部材１８の先端面１８Ｂは内側面１８Ａと垂直に交差して一方のヘッド部材１２の先端面１２Ｂよりも僅かに突出させられている。このリップ部材１８が一方のヘッド部材１２におけるリップ部とされ、上記内側面１８Ａと先端面１８Ｂとの交差稜線部がこのリップ部の刃先１８Ｃとされる。   The inner side surface 18A facing the groove 17 side of the lip member 18 is polished so as to be flush with the long side surface 12A of the head member 12 to be one inner wall surface on the front end side of the groove 17, and the lip member 18 The front end surface 18B intersects the inner side surface 18A perpendicularly and protrudes slightly from the front end surface 12B of one head member 12. The lip member 18 is a lip portion in one head member 12, and the intersecting ridge line portion between the inner side surface 18A and the front end surface 18B is a cutting edge 18C of the lip portion.

一方、図３ないし図５における右側の他方のヘッド部材１３には、上記凹所１２Ｃよりも溝１７の深さ方向および幅方向（図１において上下方向、図３ないし図５においては左右方向）に大きな断面長方形状をなす凹部１９が形成されている。すなわち、この凹部１９は、溝１７の深さ方向に垂直な底面１９Ａと、この底面１９Ａから他方のヘッド部材１３の先端側に向かう壁面１９Ｂとを有していて、この壁面１９Ｂは本実施形態では底面１９Ａと他方のヘッド部材１３の先端面１３Ｂに垂直とされている。   On the other hand, in the other head member 13 on the right side in FIGS. 3 to 5, the depth direction and the width direction of the groove 17 (vertical direction in FIG. 1, horizontal direction in FIGS. 3 to 5) rather than the recess 12C. A concave portion 19 having a large rectangular cross section is formed. That is, the concave portion 19 has a bottom surface 19A perpendicular to the depth direction of the groove 17 and a wall surface 19B from the bottom surface 19A toward the tip side of the other head member 13, and the wall surface 19B is the present embodiment. Then, the bottom surface 19A and the front end surface 13B of the other head member 13 are perpendicular to each other.

また、上記長側面１２Ａとは反対側の他方のヘッド部材１３の長側面１３Ｃから凹部１９の底面１９Ａと壁面１９Ｂとが交差する隅角部に向けては、長側面１３Ｃ側が一段大径となる段付き孔１３Ｄが、本実施形態ではこの隅角部の２等分線方向に沿って他方のヘッド部材１３を貫通するように、上記長手方向に等間隔をあけて複数（本実施形態では８つ）形成されている。   Further, from the long side surface 13C of the other head member 13 opposite to the long side surface 12A to the corner where the bottom surface 19A and the wall surface 19B of the recess 19 intersect, the long side surface 13C side has a one-step larger diameter. In this embodiment, a plurality of stepped holes 13D are provided at equal intervals in the longitudinal direction so as to penetrate the other head member 13 along the bisector direction of the corner portion (in this embodiment, 8D). One) is formed.

さらに、この長側面１３Ｃから凹部１９の壁面１９Ｂにかけては、これら長側面１３Ｃおよび壁面１９Ｂおよび溝１７の深さ方向に垂直、すなわち底面１９Ａに平行に他方のヘッド部材１３を貫通するネジ孔１３Ｅが、上記長手方向において隣接する段付き孔１３Ｄの中間に位置するように等間隔をあけて複数（本実施形態では７つ）形成されている。このうち、上記長手方向中央のネジ孔１３Ｅは、他方のヘッド部材１３を長手方向に等分する位置に形成されている。   Further, from the long side surface 13C to the wall surface 19B of the recess 19, a screw hole 13E penetrating the other head member 13 perpendicular to the depth direction of the long side surface 13C, the wall surface 19B and the groove 17, that is, parallel to the bottom surface 19A. A plurality (seven in this embodiment) are formed at equal intervals so as to be located in the middle of the stepped holes 13D adjacent in the longitudinal direction. Among these, the screw hole 13E at the center in the longitudinal direction is formed at a position for equally dividing the other head member 13 in the longitudinal direction.

そして、この凹部１９には、鋼材等の金属材料によって形成された凹部１９の断面と略同形同大の断面長方形状で、他方のヘッド部材１３の長手方向の全長に亙って延びるブロック２０が、上記段付き孔１３Ｄに挿通された引き込みボルト２１がねじ込まれることによって、凹部１９の底面１９Ａと壁面１９Ｂとに斜めに交差する方向（本実施形態では、底面１９Ａと壁面１９Ｂとが交差する隅角部の２等分線方向）に引き込まれるようにして取り付けられている。   The recess 19 is a block 20 having a rectangular cross section that is substantially the same shape and the same size as the cross section of the recess 19 formed of a metal material such as steel, and extends over the entire length of the other head member 13 in the longitudinal direction. However, when the pull-in bolt 21 inserted through the stepped hole 13D is screwed, the direction in which the bottom surface 19A and the wall surface 19B of the recess 19 intersect obliquely (in this embodiment, the bottom surface 19A and the wall surface 19B intersect). It is attached so as to be drawn in the bisector of the corner).

従って、このようにブロック２０が凹部１９に取り付けられた状態においては、ブロック２０の後端面は凹部１９の底面１９Ａと密着して着座面２０Ａとされるとともに、凹部１９の壁面１９Ｂと対向する側面２０Ｂは図４に示すように該壁面１９Ｂと密着させられる。また、このような取付状態において、ブロック２０の先端面２０Ｃは他方のヘッド部材１３の先端面１３Ｂと面一とされるとともに、ブロック２０の溝１７側を向く側面２０Ｄの後端部は、この溝１７の内壁面を形成する他方のヘッド部材１３の長側面１３Ａと面一とされる。   Therefore, in the state in which the block 20 is attached to the recess 19 in this way, the rear end surface of the block 20 is in close contact with the bottom surface 19A of the recess 19 to be a seating surface 20A, and the side surface facing the wall surface 19B of the recess 19 20B is brought into close contact with the wall surface 19B as shown in FIG. In such an attachment state, the front end surface 20C of the block 20 is flush with the front end surface 13B of the other head member 13, and the rear end portion of the side surface 20D facing the groove 17 side of the block 20 is It is flush with the long side surface 13A of the other head member 13 that forms the inner wall surface of the groove 17.

さらに、このブロック２０の溝１７側を向く側面２０Ｄの先端部には、一方のヘッド部材１２の凹所１２Ｃと同形同大の凹所２０Ｅがブロック２０の長手方向全長に亙って形成されており、この凹所２０Ｅには、やはりヘッド部材１３やブロック２０よりも硬度の高い超硬合金等の硬質材料よりなる断面長方形状のリップ部材２２がロウ付けやボルト止めによって取り付けられている。   Furthermore, a recess 20E having the same shape and size as the recess 12C of one head member 12 is formed over the entire length in the longitudinal direction of the block 20 at the tip of the side surface 20D facing the groove 17 side of the block 20. In addition, a lip member 22 having a rectangular cross section made of a hard material such as a cemented carbide having a hardness higher than that of the head member 13 or the block 20 is attached to the recess 20E by brazing or bolting.

このリップ部材２２の溝１７側を向く内側面２２Ａは、ブロック２０の側面２０Ｄの上記後端部と面一となるように研磨されており、一方のヘッド部材１２のリップ部材１８の上記内側面１８Ａと対向して溝１７の先端側の他方の内壁面とされるとともに、リップ部材２２の先端面２２Ｂはブロック２０の先端面２０Ｃおよび他方のヘッド部材１３の先端面１３Ｂよりも僅かに突出させられている。このリップ部材２２が他方のヘッド部材１３におけるリップ部とされ、上記内側面２２Ａと先端面２２Ｂとの交差稜線部がこのリップ部の刃先２２Ｃとされる。   The inner surface 22A of the lip member 22 facing the groove 17 is polished so as to be flush with the rear end portion of the side surface 20D of the block 20, and the inner surface of the lip member 18 of one head member 12 is polished. The front end surface 22B of the lip member 22 is made to protrude slightly from the front end surface 20C of the block 20 and the front end surface 13B of the other head member 13 while facing the front end 18A. It has been. The lip member 22 is the lip portion of the other head member 13, and the intersecting ridge line portion between the inner side surface 22A and the tip surface 22B is the cutting edge 22C of the lip portion.

さらに、この他方のヘッド部材１３には、ブロック２０を溝１７の上記幅方向に押圧して弾性変形させる微調整機構２３が備えられている。この微調整機構２３は、本実施形態では複数の上記ネジ孔１３Ｅにそれぞれねじ込まれる差動ネジであり、すなわち内外周にピッチの異なるネジ部を有して上記ネジ孔１３Ｅにねじ込まれる円筒状ネジ２３Ａと、この円筒状ネジ２３Ａの内周のネジ部にねじ込まれるとともにブロック２０の上記側面２０Ｃにねじ込まれる円柱状ネジ２３Ｂとを備えている。なお、この円柱状ネジ２３Ｂは側面２０Ｃに当接しているだけでもよい。また、これら円筒状ネジ２３Ａと円柱状ネジ２３Ｂのヘッド部材１３における長側面１３Ｃ側の端部には、レンチ等の作業用工具に係合可能な係合孔２３Ｃがそれぞれ形成されている。   Further, the other head member 13 is provided with a fine adjustment mechanism 23 that presses the block 20 in the width direction of the groove 17 to elastically deform it. In the present embodiment, the fine adjustment mechanism 23 is a differential screw that is screwed into each of the plurality of screw holes 13E, that is, a cylindrical screw that is screwed into the screw hole 13E having screw portions with different pitches on the inner and outer circumferences. 23A, and a cylindrical screw 23B that is screwed into an inner thread portion of the cylindrical screw 23A and screwed into the side surface 20C of the block 20. Note that the cylindrical screw 23B may be in contact with only the side surface 20C. In addition, engagement holes 23C that can be engaged with a work tool such as a wrench are formed at the ends of the cylindrical member 23A and the columnar screw 23B on the side of the long side surface 13C of the head member 13, respectively.

このように構成された塗布工具では、上述のように引き込みボルト２１によって引き込まれてブロック２０が凹部１９に取り付けられた状態から、微調整機構２３の差動ネジにおける円筒状ネジ２３Ａをネジ孔１３Ｅにねじ込んでゆくと、円柱状ネジ２３Ｂは回転することなく円筒状ネジ２３Ａの内外周のピッチの差分で溝１７側に突出し、ブロック２０を溝１７の幅方向に押圧して弾性変形させるので、リップ部材１８、２２の刃先１８Ｃ、２２Ｃの間の溝１７の幅が微調整される。   In the coating tool configured as described above, the cylindrical screw 23A in the differential screw of the fine adjustment mechanism 23 is inserted into the screw hole 13E from the state in which the block 20 is attached to the recess 19 by the drawing bolt 21 as described above. Since the cylindrical screw 23B protrudes toward the groove 17 by the difference in pitch between the inner and outer circumferences of the cylindrical screw 23A without rotating, and the block 20 is pressed in the width direction of the groove 17 and elastically deformed. The width of the groove 17 between the cutting edges 18C and 22C of the lip members 18 and 22 is finely adjusted.

このとき、ブロック２０は、その着座面２０Ａを溝１７の深さ方向に垂直な凹部１９の底面１９Ａに密着させているので、ブロック２０の弾性変形は溝１７の深さ方向に垂直な方向、すなわち溝１７の上記幅方向だけの変形となり、ブロック２０やリップ部材２２が大きく傾いて刃先２２Ｃの位置が溝１７の深さ方向に変位することはない。従って、この溝１７の深さ方向における刃先２２Ｃの真直度を維持したまま溝１７の幅の微調整を行うことができ、均一な塗布膜を形成することができる。   At this time, since the seating surface 20A of the block 20 is in close contact with the bottom surface 19A of the concave portion 19 perpendicular to the depth direction of the groove 17, the elastic deformation of the block 20 occurs in a direction perpendicular to the depth direction of the groove 17, That is, the groove 17 is deformed only in the width direction, and the block 20 and the lip member 22 are not greatly inclined, and the position of the blade edge 22 </ b> C is not displaced in the depth direction of the groove 17. Accordingly, the width of the groove 17 can be finely adjusted while maintaining the straightness of the cutting edge 22C in the depth direction of the groove 17, and a uniform coating film can be formed.

また、このように刃先２２Ｃの位置が溝１７の深さ方向に変化することがないため、溝１７の幅の変化量をそのまま塗工厚みの変化量に反映させることができ、溝１７の幅の変化量に対して実際の塗工厚みの変化量が小さくなるのを防ぐことができ、幅広い塗工厚みの変化に対応することができる。しかも、溝１７の幅は塗布液が吐出される刃先１８Ｃ、２２Ｃの部分で微調整されるので、塗布液の流量や塗工厚みを確実に制御することが可能となる。   Further, since the position of the cutting edge 22C does not change in the depth direction of the groove 17 in this way, the change amount of the width of the groove 17 can be reflected in the change amount of the coating thickness as it is. Therefore, it is possible to prevent the actual amount of change in coating thickness from becoming small with respect to the amount of change in thickness, and to cope with a wide range of changes in coating thickness. Moreover, since the width of the groove 17 is finely adjusted at the portions of the cutting edges 18C and 22C from which the coating liquid is discharged, the flow rate of the coating liquid and the coating thickness can be reliably controlled.

さらに、微調整機構２３によって調整されるブロック２０およびリップ部材２２は、本実施形態では１つであるので、部品数が必要以上に多くなって管理が煩雑となることもない。ただし、本実施形態では、上記他方のヘッド部材１３に取り付けられるブロック２０およびリップ部材２２だけを弾性変形させているが、一方のヘッド部材１２にもブロックを介してリップ部材１８を取り付けてもよく、その場合でも部品数が必要以上に多くなることはない。   Furthermore, since the block 20 and the lip member 22 adjusted by the fine adjustment mechanism 23 are one in this embodiment, the number of parts is not increased more than necessary, and management is not complicated. However, in this embodiment, only the block 20 and the lip member 22 attached to the other head member 13 are elastically deformed. However, the lip member 18 may be attached to one head member 12 via the block. Even in that case, the number of parts does not increase more than necessary.

また、本実施形態では、ブロック２０が引き込みボルト２１によって凹部１９の底面１９Ａと壁面１９Ｂとに斜めに交差する方向に引き込まれて取り付けられており、これによってブロック２０の取付安定性を確保して刃先２２Ｃの真直度を一層確実に維持することができるとともに、微調整機構２３による溝１７の幅調整の精度の向上を図ることも可能となる。   Moreover, in this embodiment, the block 20 is pulled and attached to the bottom surface 19A and the wall surface 19B of the recess 19 in a direction obliquely intersecting with the pull-in bolt 21, thereby securing the mounting stability of the block 20. The straightness of the cutting edge 22C can be more reliably maintained, and the accuracy of the width adjustment of the groove 17 by the fine adjustment mechanism 23 can be improved.

なお、本実施形態では、この引き込みボルト２１が挿通される段付き孔１３Ｄが、底面１９Ａと壁面１９Ｂが交差する隅角部に向けて、この隅角部の２等分線方向に沿って形成されているが、段付き孔１３Ｄは底面１９Ａや壁面１９Ｂに開口していてもよく、また上記２等分線方向から傾いて形成されていてもよい。   In the present embodiment, the stepped hole 13D through which the pull-in bolt 21 is inserted is formed along the bisector direction of the corner portion toward the corner portion where the bottom surface 19A and the wall surface 19B intersect. However, the stepped hole 13D may open to the bottom surface 19A or the wall surface 19B, or may be formed to be inclined from the bisector direction.

さらに、本実施形態では、上記微調整機構２３が差動ネジであり、円筒状ネジ２３Ａの内外周のネジ部のピッチの差に応じて円柱状ネジ２３Ｂを微小に出没させてブロック２０を押圧することにより弾性変形させることができるので、より細かい溝１７の幅調整を行うことが可能となる。ただし、この微調整機構２３は、例えば油圧機構等によって凹部１９の壁面１９Ｂを部分的に膨らませてブロック２０を押圧するものでもよく、また塗工厚みを測定しつつリニアアクチュエータ等によって塗布作業中に自動でブロック２０を押圧するようなものでもよい。   Further, in the present embodiment, the fine adjustment mechanism 23 is a differential screw, and the cylindrical screw 23B is slightly protruded and depressed according to the pitch difference between the inner and outer peripheral screw portions of the cylindrical screw 23A to press the block 20. Since it can be elastically deformed by doing so, it becomes possible to adjust the width | variety of the groove | channel 17 finer. However, this fine adjustment mechanism 23 may be a mechanism that partially inflates the wall surface 19B of the recess 19 by a hydraulic mechanism or the like and presses the block 20, and during the coating operation by a linear actuator or the like while measuring the coating thickness. It may be such that the block 20 is automatically pressed.

次に、本発明の実施例を挙げて、本発明の効果について実証する。本実施例では、上記実施形態に基づき、一方のヘッド部材１２のリップ部材１８の厚さが約２．８ｍｍ、他方のヘッド部材１３におけるブロック２０のリップ部材２２の厚さが約２．８ｍｍ、溝１７の幅が約０．３ｍｍの塗布工具を製造し、この塗布工具において工具本体１１の長手方向中央部（図２におけるＢＢ断面位置）における微調整機構２３によってブロック２０を押圧して溝１７の幅方向に弾性変形させ、溝１７の幅を調整無しの状態から５μｍ、１７μｍ、３６μｍ狭めた際のリップ部材１８、２２の内側面１８Ａ、２２Ａと先端面１８Ｂ、２２Ｂおよび刃先１８Ｃ、２２Ｃの変化量を測定した。これを実施例１として図１０に示す。ただし、この図１０においては図３ないし図５とは逆に、右側が一方のヘッド部材１２であり、左側が他方のヘッド部材１３であり、横軸は他方のヘッド部材１３におけるリップ部材２２の内側面２２Ａとは反対側の側面からの溝幅方向の距離である。   Next, examples of the present invention will be given to demonstrate the effects of the present invention. In this example, based on the above embodiment, the thickness of the lip member 18 of one head member 12 is about 2.8 mm, the thickness of the lip member 22 of the block 20 in the other head member 13 is about 2.8 mm, A coating tool having a groove 17 width of about 0.3 mm is manufactured, and in this coating tool, the block 20 is pressed by the fine adjustment mechanism 23 in the longitudinal center portion (BB cross-sectional position in FIG. 2) of the tool body 11 to form the groove 17. The inner surfaces 18A and 22A of the lip members 18 and 22 and the tip surfaces 18B and 22B and the cutting edges 18C and 22C when the width of the groove 17 is narrowed by 5 μm, 17 μm and 36 μm from the state without adjustment. The amount of change was measured. This is shown in FIG. However, in FIG. 10, contrary to FIGS. 3 to 5, the right side is one head member 12, the left side is the other head member 13, and the horizontal axis is the lip member 22 of the other head member 13. The distance in the groove width direction from the side surface opposite to the inner side surface 22A.

また、この実施例１に対する比較例として、上述した図６ないし図９に基づく従来の塗布工具において、切込部７が形成されていない一方のヘッド部材２のリップ部６の厚さが３．０ｍｍ、切込部７が形成された他方のヘッド部材３のリップ部６の厚さが３．０ｍｍ、溝５の幅が０．５ｍｍの塗布工具を製造し、この塗布工具において工具本体１の長手方向中央部（図７におけるＡＡ断面位置）における微調整機構８（差動ネジ）によって一方のヘッド部材２の先端部を押圧して溝５の幅方向に弾性変形させ、実施例１と同様に調整無しの状態から溝５の幅を５μｍ、１７μｍ、３６μｍ狭めた際のリップ部６の先端面６Ａ、刃先６Ｂおよび内側面６Ｃの変化量を測定した。これを比較例１として図１１に示す。ただし、この図１１においても図８ないし図９とは逆に、右側が一方のヘッド部材２であり、左側が他方のヘッド部材３であり、横軸はヘッド部材２におけるリップ部６の内側面６Ｃとは反対側の側面からの溝幅方向の距離である。   As a comparative example with respect to the first embodiment, in the conventional coating tool based on the above-described FIGS. 6 to 9, the thickness of the lip portion 6 of one head member 2 in which the notch portion 7 is not formed is 3. A coating tool having a thickness of 3.0 mm and a width of the groove 5 of 0.5 mm of the lip portion 6 of the other head member 3 on which the cut portion 7 is formed is manufactured. The tip of one head member 2 is pressed by the fine adjustment mechanism 8 (differential screw) at the longitudinal center (AA cross-sectional position in FIG. 7) to be elastically deformed in the width direction of the groove 5. When the width of the groove 5 was narrowed by 5 μm, 17 μm, and 36 μm from the state without adjustment, the amount of change in the tip surface 6A, the blade edge 6B, and the inner surface 6C of the lip portion 6 was measured. This is shown in FIG. However, also in FIG. 11, contrary to FIGS. 8 to 9, the right side is one head member 2, the left side is the other head member 3, and the horizontal axis is the inner surface of the lip portion 6 in the head member 2. The distance in the groove width direction from the side surface opposite to 6C.

これら図１０および図１１の結果より、比較例１では溝５の幅を−５μｍ狭めたところで既に刃先６Ｂが溝５の深さ方向に約０．００１ｍｍ（１μｍ）後退し、溝５の幅を−３６μｍ狭めたところでは溝５の深さ方向に約０．００４ｍｍ（４μｍ）後退していたのに対し、実施例１では溝１７の幅を３６μｍ狭めても刃先２２Ｃの変化量は約０．００１ｍｍ（１μｍ）程度であった。従って、実施例１の方が比較例１よりも溝１７の深さ方向における刃先２２Ｃの真直度が高く、均一な塗布膜を形成できることが分かる。   From the results of FIGS. 10 and 11, in Comparative Example 1, when the width of the groove 5 is narrowed by −5 μm, the cutting edge 6 </ b> B has already receded by about 0.001 mm (1 μm) in the depth direction of the groove 5. Whereas −36 μm narrowed, the groove 5 receded by about 0.004 mm (4 μm) in the depth direction, whereas in Example 1, the amount of change in the cutting edge 22C was about 0. It was about 001 mm (1 μm). Therefore, it can be seen that the straightness of the cutting edge 22C in the depth direction of the groove 17 is higher in Example 1 than in Comparative Example 1, and a uniform coating film can be formed.

つぎに、これら実施例１と比較例１の塗布工具を用いて、実際に塗布を行い、その際の溝５、１７の幅の変化量と塗工厚み変化量の関係を測定した。これらを実施例２および比較例２として図１２に示す。なお、これら実施例２と比較例２における塗布工具の工具本体１、１１の長手方向の全長は４５０ｍｍ、溝５、１７の長さは３５０ｍｍ、塗工速度（工具本体１、１１と被塗布物との相対移動速度）は４０ｍｍ／ｓｅｃ、調整無しの状態の塗工厚みは０．１ｍｍ（１００μｍ）であり、塗布液としては粘度２０００ｃｐｓのリチウム電池用負極剤を用いた。   Next, application was actually performed using the application tools of Example 1 and Comparative Example 1, and the relationship between the change in the width of the grooves 5 and 17 and the change in the application thickness was measured. These are shown in FIG. 12 as Example 2 and Comparative Example 2. In addition, the overall length in the longitudinal direction of the tool bodies 1 and 11 of the coating tool in Example 2 and Comparative Example 2 is 450 mm, the length of the grooves 5 and 17 is 350 mm, and the coating speed (the tool bodies 1 and 11 and the object to be coated). Relative coating speed) was 40 mm / sec, the coating thickness without adjustment was 0.1 mm (100 μm), and a negative electrode agent for lithium batteries having a viscosity of 2000 cps was used as the coating solution.

この図１２の結果より、実施例２では溝５の幅を３０μｍ以上狭めても塗工厚みの変化量は１０μｍにも満たなかったのに対し、実施例２では溝１７の幅を１７μｍ狭めたところで塗工厚みの変化量は１０μｍを超え、溝１７の幅を３６μｍ狭めたところでは、約３５μｍと、比較例２の最大塗工厚み変化量の約４倍もの変化量を得ることができた。これにより、本発明の塗布工具では、より広い範囲の塗工厚み量の変化に対応することが可能であることが分かる。   From the result shown in FIG. 12, in Example 2, even if the width of the groove 5 was reduced by 30 μm or more, the change in coating thickness was less than 10 μm, whereas in Example 2, the width of the groove 17 was reduced by 17 μm. By the way, the change amount of the coating thickness exceeded 10 μm, and when the width of the groove 17 was narrowed by 36 μm, it was possible to obtain a change amount of about 35 μm, which is about four times the maximum change amount of the coating thickness of Comparative Example 2. . Thereby, in the coating tool of this invention, it turns out that it can respond to the change of the coating thickness amount of a wider range.
