Description

本発明は、シート状部材やパネル状部材などの被塗布物の表面に、塗布液を塗布する際に使用される塗布工具に関するものである。 The present invention relates to a coating tool used when a coating solution is applied to the surface of an object to be coated such as a sheet-like member or a panel-like member.

従来、この種の塗布工具として、例えば下記特許文献１の図４等に示されるような、一対のヘッド部材が隣接配置され、これらヘッド部材同士の間に形成されたマニホールド、及び該マニホールドに連通するとともにヘッド部材の先端側に向けて開口されたスリットを通して、被塗布物に塗布液を塗布する構成のスロットダイが知られている。塗布工具に供給される塗布液は、ヘッド部材内（ヘッド部材同士の突き合わせ面部分）のマニホールドに一時的に保持され、該マニホールドからスリットへと流通し、スリットからヘッド部材の先端部（刃先エッジ）を介して被塗布物に塗布される。このようにマニホールドからスリットを通して塗布液が吐出されることで、被塗布物に塗布液が均一に塗布されるようになされている。 Conventionally, as a coating tool of this type, for example, a pair of head members as shown in FIG. 4 of the following Patent Document 1, for example, are arranged adjacent to each other, and communicated with the manifold. In addition, there is known a slot die having a configuration in which a coating liquid is applied to an object to be coated through a slit opened toward the front end side of the head member. The coating liquid supplied to the coating tool is temporarily held in the manifold in the head member (abutting surface portion between the head members), flows from the manifold to the slit, and from the slit to the tip of the head member (edge edge) ) To be applied to the object to be coated. As described above, the coating liquid is discharged from the manifold through the slit, so that the coating liquid is uniformly applied to the object to be coated.

このような塗布工具においては、塗布液の粘度が、例えば中高粘度である場合などに、マニホールドからスリットへと塗布液が均一に供給されにくくなり、塗布精度が確保できないことがある。具体的に、塗布液の粘度が高い場合には、マニホールドの内圧がばらつきやすくなるとともに、スリットの延在する方向の中央部から被塗布物に塗布される塗布液の膜（層）厚が、該スリットの両端部から塗布される塗布液の膜厚よりも厚くなりやすい。このような現象を抑制して塗布精度を確保するため、ヘッド部材のマニホールドを切削等により加工して、その形状を塗布液に合わせて適宜変更することが行われている。 In such a coating tool, when the viscosity of the coating solution is, for example, medium to high viscosity, it is difficult to uniformly supply the coating solution from the manifold to the slit, and thus the coating accuracy may not be ensured. Specifically, when the viscosity of the coating liquid is high, the internal pressure of the manifold is likely to vary, and the film (layer) thickness of the coating liquid applied to the coating object from the center in the direction in which the slit extends, It tends to be thicker than the film thickness of the coating solution applied from both ends of the slit. In order to suppress such a phenomenon and ensure application accuracy, the manifold of the head member is processed by cutting or the like, and the shape thereof is appropriately changed according to the application liquid.

特開２００２−０１８３３９号公報JP 2002-018339 A

しかしながら、前述した従来の塗布工具においては、下記の課題を有していた。
すなわち、塗布液に対応してヘッド部材のマニホールド形状を変更するには、切削（フライス）加工、磨き加工及び研磨加工等が必要であり、加工が煩雑で多くの時間を要し、製作コストが嵩んでいた。 However, the above-described conventional coating tool has the following problems.
That is, in order to change the manifold shape of the head member corresponding to the coating liquid, cutting (milling) processing, polishing processing, polishing processing, and the like are necessary, and processing is complicated and requires a lot of time, and the manufacturing cost is high. It was bulky.

また、ヘッド部材のマニホールド形状を変更した後、異なる塗布液の塗工に当該ヘッド部材を用いると、塗布精度が確保できないおそれがある。つまり、ヘッド部材を種々の塗布液の塗工において共用することは難しく、各塗布液に応じて、高価なヘッド部材を多数用意しなければならなかった。 Further, if the head member is used for coating different coating liquids after changing the manifold shape of the head member, there is a possibility that the coating accuracy cannot be ensured. That is, it is difficult to share the head member in various coating liquid coatings, and it is necessary to prepare a large number of expensive head members for each coating liquid.

本発明は、このような事情に鑑みてなされたものであって、塗布液に応じてマニホールド形状を容易に変更でき、これにより塗布精度を安定して高めることができ、かつ、コストを削減できる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 in view of such circumstances, and the manifold shape can be easily changed in accordance with the coating liquid, whereby the coating accuracy can be stably increased and the cost can be reduced. The object is to provide a coating tool.

このような課題を解決して、前記目的を達成するために、本発明は以下の手段を提案している。
すなわち、本発明は、複数のヘッド部材が隣接配置され、隣り合う前記ヘッド部材同士の間に形成されたマニホールド、及び該マニホールドに連通するとともに前記ヘッド部材の先端側に向けて開口されたスリットを通して、被塗布物に塗布液を塗布する塗布工具であって、前記マニホールドは、前記ヘッド部材に形成される本体部と、該本体部の前記先端側に隣接配置される調整部と、を備え、前記調整部は、前記ヘッド部材に着脱可能に装着された換装部材に形成され、前記換装部材は前記ヘッド部材の長手方向に延びた形状を有し、前記ヘッド部材を長手方向に貫通する溝部に対して、前記ヘッド部材の長手方向の端面から出し入れ可能であることを特徴とする。 In order to solve such problems and achieve the above object, the present invention proposes the following means.
That is, according to the present invention, a plurality of head members are arranged adjacent to each other, and through a manifold formed between the adjacent head members, and a slit that opens to the leading end side of the head member while communicating with the manifold. An application tool for applying a coating liquid to an object to be coated, wherein the manifold includes a main body portion formed on the head member, and an adjustment portion disposed adjacent to the distal end side of the main body portion, The adjustment portion is formed in a replacement member that is detachably attached to the head member, the replacement member has a shape extending in a longitudinal direction of the head member, and a groove portion that penetrates the head member in the longitudinal direction. On the other hand, the head member can be taken in and out from the end face in the longitudinal direction .

本発明の塗布工具によれば、マニホールドが本体部と調整部とを備えており、本体部はヘッド部材に形成されている一方、調整部は該ヘッド部材に着脱可能に装着された換装部材に形成されている。この構成により、マニホールドのうちヘッド部材のスリット開口部（刃先エッジ）に近く、塗布精度に影響しやすい調整部の形状を、換装部材を交換することで容易に、かつ迅速に変更することができる。 According to the coating tool of the present invention, the manifold includes the main body portion and the adjustment portion, and the main body portion is formed on the head member, while the adjustment portion is attached to the replacement member that is detachably attached to the head member. Is formed. With this configuration, the shape of the adjustment unit that is close to the slit opening (blade edge) of the head member and easily affects the coating accuracy of the manifold can be easily and quickly changed by replacing the replacement member. .

具体的に、本発明によれば、塗布液に応じてマニホールド形状を変更するにあたり、従来のようにヘッド部材を切削等により加工する必要はなく、ヘッド部材に装着された換装部材を取り外すとともに、前記塗布液に適した調整部の形状を有する他の換装部材に交換することで、簡便に対応することができる。従って、例えば中高粘度の塗布液を用いて塗工するような場合であっても、被塗布物に塗布される塗布液の膜（層）厚を、スリットが延在する方向に沿って簡単に均一にすることができる。
そして、この構成によれば、性質の似た異なる塗布液の塗工に同一のヘッド部材を用いることが比較的簡単に行え、高価なヘッド部材を種々の塗布液に応じて多数（複数種類）用意しなければならないという事態を回避しやすい。 Specifically, according to the present invention, when changing the manifold shape according to the coating liquid, it is not necessary to process the head member by cutting or the like as in the prior art, while removing the replacement member attached to the head member, By replacing with another replacement member having the shape of the adjustment unit suitable for the coating liquid, it is possible to easily cope with it. Therefore, for example, even when coating is performed using a medium-high viscosity coating liquid, the film (layer) thickness of the coating liquid applied to the object to be coated can be easily adjusted along the direction in which the slit extends. It can be made uniform.
According to this configuration, it is relatively easy to use the same head member for coating different coating liquids having similar properties, and many (a plurality of types) of expensive head members can be used according to various coating liquids. It is easy to avoid the situation that you have to prepare.

さらに、換装部材には、マニホールド全体のうち調整部の形状のみが付与されていればよいことから、該換装部材の外形を小さくできる。従って、塗布液に合わせて複数種類の換装部材を用意する場合であっても、部品の維持管理や交換作業時の取り扱いが容易である。 Furthermore, since only the shape of the adjustment portion of the entire manifold needs to be given to the replacement member, the outer shape of the replacement member can be reduced. Accordingly, even when a plurality of types of replacement members are prepared in accordance with the coating liquid, it is easy to maintain and manage parts and handle them during replacement work.

また、換装部材は、製造時の加工精度が被塗布物に塗布液を塗布するヘッド部材ほどには要求されないため、安価に製造できる。また、ヘッド部材のような剛性も必要とされないため、例えば、換装部材として重量（比重）が軽く取り扱いやすい材料（アルミニウムや樹脂材料等）を選択することも可能であり、この場合、換装部材の交換作業をより簡便に行うことができる。 In addition, the replacement member can be manufactured at low cost because the processing accuracy at the time of manufacture is not as high as that of the head member that applies the coating liquid to the object to be coated. Further, since rigidity as in the head member is not required, for example, it is possible to select a material (aluminum, resin material, etc.) having a light weight (specific gravity) and easy to handle as the replacement member. Exchange work can be performed more simply.

このように、本発明の塗布工具によれば、塗布液に応じてマニホールド形状を容易に変更でき、これにより塗布精度を安定して高めることができ、かつ、コストを削減できる。そして、低粘度から中高粘度まで幅広い塗布液の塗工に容易にかつ廉価に対応できる。 As described above, according to the coating tool of the present invention, the manifold shape can be easily changed according to the coating solution, whereby the coating accuracy can be stably increased and the cost can be reduced. And it can respond easily and inexpensively to coating of a wide range of coating solutions from low viscosity to medium and high viscosity.

また、本発明の塗布工具において、前記調整部から前記スリットの開口部までの距離が、該スリットが延在する方向に沿って変化するように構成されることとしてもよい。 Moreover, the coating tool of this invention WHEREIN: It is good also as a structure from which the distance from the said adjustment part to the opening part of the said slit changes along the direction where this slit extends.

この場合、マニホールドの調整部からスリットの開口部までの距離に応じて、該スリットから被塗布物に塗布される塗布液の膜厚が調整される。具体的に、スリットの延在方向において、塗布液の膜厚が薄くなりやすい箇所（例えばスリットの延在方向に沿う両端部など）については、調整部からスリットの開口部までの距離を短く設定することで、塗布液が吐出されやすくなるとともに、膜厚を所定範囲に確保しやすくなる。また、塗布液の膜厚が厚くなりやすい箇所（例えばスリットの延在方向に沿う中央部など）については、調整部からスリットの開口部までの距離を長く設定することで、塗布液が吐出されにくくなるとともに、膜厚を所定範囲に確保しやすくなる。 In this case, the film thickness of the coating liquid applied from the slit to the coating object is adjusted in accordance with the distance from the manifold adjustment portion to the slit opening. Specifically, in locations where the coating film thickness tends to be thin in the slit extension direction (for example, both ends along the slit extension direction), the distance from the adjustment portion to the slit opening is set short. By doing so, the coating liquid can be easily discharged and the film thickness can be easily secured within a predetermined range. In addition, at locations where the coating solution tends to be thick (for example, the central portion along the slit extending direction), the coating solution is discharged by setting the distance from the adjustment unit to the opening of the slit long. It becomes difficult and it becomes easy to ensure a film thickness in a predetermined range.

すなわち、上記構成によれば、塗布液の性質（粘度など）や塗工条件に応じて、スリットの延在する方向に沿う各部位において、調整部からスリットの開口部までの距離を適宜設定することにより、前述した塗布精度を安定して高めるという効果を簡単に、かつ顕著に得ることができるのである。 That is, according to the said structure, according to the property (viscosity etc.) and application conditions of a coating liquid, in each site | part along the direction where a slit extends, the distance from an adjustment part to the opening part of a slit is set suitably. As a result, the above-described effect of stably increasing the coating accuracy can be obtained easily and significantly.

また、本発明の塗布工具において、前記調整部のうち、前記スリットが延在する方向に沿う両端部は、該両端部の間に位置する中間部よりも前記先端側に配置されていることとしてもよい。 Moreover, in the coating tool of the present invention, among the adjustment portion, both end portions along the direction in which the slit extends are arranged closer to the tip side than an intermediate portion located between the both end portions. Also good.

一般に、例えば、中高粘度の塗布液を用いて塗工する際には、低粘度の塗布液を用いる場合に比べて、マニホールドの内圧がばらつきやすくなるとともに、スリットの開口部のうち、該スリットの延在する方向の両端部から被塗布物に塗布される塗布液の膜厚が、前記両端部の間に位置する中間部から塗布される塗布液の膜厚よりも薄くなりがちである。
従って、本発明の上記構成とすることにより、スリットの開口部のうち、特に該スリットの両端部から吐出される塗布液の膜厚が十分に確保されて、被塗布物に対して塗布液がより均一に塗布されることとなる。 In general, for example, when coating with a medium-high viscosity coating liquid, the internal pressure of the manifold is more likely to vary than in the case of using a low-viscosity coating liquid, and among the slit openings, the slit The film thickness of the coating liquid applied to the object to be coated from both ends in the extending direction tends to be thinner than the film thickness of the coating liquid applied from the intermediate part located between the both ends.
Therefore, by adopting the above-described configuration of the present invention, a sufficient thickness of the coating liquid discharged from both ends of the slit, in particular, of the opening of the slit is sufficiently secured, so that the coating liquid is applied to the object to be coated. It will be applied more uniformly.

また、本発明の塗布工具において、隣り合う前記ヘッド部材同士のうち、一方のヘッド部材に装着された前記換装部材の前記調整部は、他方のヘッド部材側に向かうに従い前記先端側に向けて傾斜するテーパ面を有することとしてもよい。 Moreover, in the coating tool of the present invention, among the adjacent head members, the adjustment portion of the replacement member attached to one head member is inclined toward the distal end side toward the other head member side. It is good also as having a taper surface to do.

この場合、マニホールドの本体部から調整部を通ってスリットに供給される塗布液が、該調整部において乱流を生じるようなことが抑制される。これにより、調整部の形状に応じて、塗布液がスリットの延在方向に沿う各部位において狙った膜厚の範囲内となるように吐出されやすくなって、塗布精度をさらに安定的に高めることができる。 In this case, it is suppressed that the coating liquid supplied from the main body portion of the manifold to the slit through the adjustment portion causes turbulence in the adjustment portion. As a result, according to the shape of the adjusting portion, the coating liquid can be easily discharged so as to be within the targeted film thickness range at each site along the extending direction of the slit, and the coating accuracy can be further stably improved. Can do.

本発明の塗布工具によれば、塗布液に応じてマニホールド形状を容易に変更でき、これにより塗布精度を安定して高めることができ、かつ、コストを削減できる。 According to the coating tool of the present invention, the manifold shape can be easily changed in accordance with the coating solution, whereby the coating accuracy can be stably increased and the cost can be reduced.

以下、本発明の一実施形態に係る塗布工具１について、図面を参照して説明する。
本実施形態の塗布工具１は、例えば可撓性を有するシート状部材やパネル状部材などの被塗布物の表面に、塗布液を所定の膜（層）厚となるように塗布するスロットダイである。この塗布工具１は、低粘度から中高粘度まで種々の塗布液に適用可能であるが、例えば二次電池用途など、特に中高粘度のスラリー（塗布液）を被塗布物に塗工する場合に適している。 Hereinafter, application tool 1 concerning one embodiment of the present invention is explained with reference to drawings.
The application tool 1 of the present embodiment is a slot die that applies an application liquid to a surface of an object to be applied such as a flexible sheet-like member or panel-like member so as to have a predetermined film (layer) thickness. is there. This coating tool 1 can be applied to various coating liquids from low viscosity to medium and high viscosity, and is particularly suitable for application of a medium and high viscosity slurry (coating liquid) to an object to be coated, such as for secondary batteries. ing.

図１及び図２に示すように、本実施形態の塗布工具１は、対向配置される一対のヘッド部材２と、これらヘッド部材２同士の間に形成されたマニホールド４と、該マニホールド４に連通するとともにヘッド部材２の先端側に向けて開口されたスリット３と、ヘッド部材２に着脱可能に装着されてマニホールド４の一部（後述する調整部１２）を構成する換装部材５と、を備えている。
ここで、ヘッド部材２は、長尺の矩形板状又はブロック状をなしており、上記一対のヘッド部材２同士は、その厚さ方向に隣接するように対向配置されている。本明細書においては、ヘッド部材２の延在する方向を塗布工具１の長手方向Ｌといい、ヘッド部材２の厚さ方向を塗布工具１の幅方向Ｗといい、これら長手方向Ｌ及び幅方向Ｗに垂直な方向を塗布工具１の高さ方向Ｈという。また、高さ方向Ｈのうち、ヘッド部材２間からスリット３が外部に開口される向き（被塗布物に塗布液が吐出される向き）を先端側（ヘッド部材２の先端側であり、図１及び図２における上側）といい、上記スリット３が外部に開口される向きとは反対側を基端側（ヘッド部材２の基端側であり、図１及び図２における下側）という。 As shown in FIG. 1 and FIG. 2, the application tool 1 of the present embodiment includes a pair of head members 2 arranged opposite to each other, a manifold 4 formed between the head members 2, and a communication with the manifold 4. In addition, a slit 3 opened toward the front end side of the head member 2 and a replacement member 5 that is detachably attached to the head member 2 and constitutes a part of the manifold 4 (adjustment portion 12 described later). ing.
Here, the head member 2 has a long rectangular plate shape or block shape, and the pair of head members 2 are arranged to face each other so as to be adjacent to each other in the thickness direction. In this specification, the direction in which the head member 2 extends is referred to as the longitudinal direction L of the coating tool 1, and the thickness direction of the head member 2 is referred to as the width direction W of the coating tool 1. A direction perpendicular to W is referred to as a height direction H of the coating tool 1. Further, in the height direction H, the direction in which the slit 3 is opened to the outside from between the head members 2 (the direction in which the coating liquid is discharged to the application object) is the front end side (the front end side of the head member 2, 1 and the upper side in FIG. 2, and the side opposite to the direction in which the slit 3 is opened to the outside is called the base end side (the base end side of the head member 2, the lower side in FIGS. 1 and 2).

この塗布工具１は、ヘッド部材２の先端（刃先エッジ）を被塗布物に対向配置させるとともに、ヘッド部材２間に開口するスリット３の延在方向（ヘッド部材２の長手方向Ｌ）を被塗布物の幅方向に一致させるようにして不図示の塗布装置に装着される。そして、塗布液タンクから供給ポンプによってマニホールド４内に供給される塗布液が、該マニホールド４からスリット３内を流通してヘッド部材２の先端（スリット３開口部）から吐出されることにより、この塗布工具１の幅方向Ｗに沿うように移動する被塗布物の表面に対して、塗布液が所定の膜厚（層厚）となるように塗布される。 The coating tool 1 places the tip end (blade edge) of the head member 2 opposite to the object to be coated and applies the extending direction of the slit 3 (longitudinal direction L of the head member 2) opened between the head members 2. It is attached to a coating apparatus (not shown) so as to coincide with the width direction of the object. Then, the coating liquid supplied from the coating liquid tank into the manifold 4 by the supply pump flows through the slit 3 from the manifold 4 and is discharged from the tip of the head member 2 (slit 3 opening). The coating liquid is applied so as to have a predetermined film thickness (layer thickness) on the surface of the object to be applied that moves along the width direction W of the application tool 1.

ヘッド部材２は、ステンレス鋼等の金属材料からなり、図１に示される縦断面視（側断面視）で、台形状をなしている。ヘッド部材２において、前記台形の上底をなすとともに幅方向Ｗの外側を向く外面７、及び、前記台形の下底をなすとともに幅方向Ｗの内側を向く内面（突き合わせ面）８は、それぞれ幅方向Ｗに垂直な平面状をなしている。隣り合う一対のヘッド部材２の内面８同士は、隙間をあけて対向配置されており、前記隙間にスリット３が画成されている。 The head member 2 is made of a metal material such as stainless steel, and has a trapezoidal shape in a longitudinal sectional view (side sectional view) shown in FIG. In the head member 2, the outer surface 7 that forms the upper base of the trapezoid and faces the outer side in the width direction W, and the inner surface (butting surface) 8 that forms the lower base of the trapezoid and faces the inner side of the width direction W are respectively wide. A planar shape perpendicular to the direction W is formed. The inner surfaces 8 of a pair of adjacent head members 2 are opposed to each other with a gap, and a slit 3 is defined in the gap.

スリット３は、一対のヘッド部材２の内面８（後述するエッジ部材６の内面８を含む）と、該ヘッド部材２同士の間に配設された不図示のシムとによって画成された塗布液の流通空間（隙間）であり、ヘッド部材２間においてマニホールド４に対応する部位から先端側の領域に形成されているとともに、ヘッド部材２の先端側に向けて開口されている一方、ヘッド部材２の基端側及び長手方向Ｌの両側に向けては開口されていない。 The slit 3 is a coating liquid defined by inner surfaces 8 (including inner surfaces 8 of edge members 6 described later) of the pair of head members 2 and shims (not shown) disposed between the head members 2. And is formed in a region on the front end side from a portion corresponding to the manifold 4 between the head members 2 and opened toward the front end side of the head member 2. It is not opened toward the base end side and both sides in the longitudinal direction L.

また、ヘッド部材２において基端側を向く基端面９は、高さ方向Ｈに垂直な平面となっている。ヘッド部材２において先端側を向く先端面１０は、図１の縦断面視で、幅方向Ｗの内側（つまり幅方向Ｗの中央側、スリット３側）に向かうに従い漸次先端側に向かって傾斜している。 Further, the base end surface 9 facing the base end side in the head member 2 is a plane perpendicular to the height direction H. The front end surface 10 facing the front end side in the head member 2 is gradually inclined toward the front end side as it goes to the inner side in the width direction W (that is, the center side in the width direction W, the slit 3 side) in the longitudinal sectional view of FIG. ing.

本実施形態では、一対のヘッド部材２の先端部に、超硬合金等の硬質材料からなるエッジ部材６がそれぞれ配設されており、これらエッジ部材６同士はスリット３を画成する隙間をあけて対向配置されている。エッジ部材６は、長手方向Ｌに長尺とされた矩形板状をなしており、図示の例では、ヘッド部材２の先端面１０から先端側に突出している。そして、エッジ部材６の先端部（刃先エッジ）同士の間に、スリット３の開口部が形成されている。尚、エッジ部材６は設けられていなくてもよく、この場合、ヘッド部材２において先端面１０と内面８とがなす稜線部分が、該ヘッド部材２の刃先エッジとされる。 In the present embodiment, edge members 6 made of a hard material such as cemented carbide are respectively disposed at the distal ends of the pair of head members 2, and the edge members 6 form a gap that defines the slit 3. Are opposed to each other. The edge member 6 has a rectangular plate shape elongated in the longitudinal direction L. In the illustrated example, the edge member 6 protrudes from the distal end surface 10 of the head member 2 toward the distal end side. And the opening part of the slit 3 is formed between the front-end | tip parts (blade edge) of the edge member 6. FIG. Note that the edge member 6 may not be provided, and in this case, a ridge line portion formed by the tip surface 10 and the inner surface 8 in the head member 2 is a cutting edge of the head member 2.

一対のヘッド部材２のうち、一方のヘッド部材２Ａにおける高さ方向Ｈの中央部には、マニホールド４及び換装部材５が配置されている。本実施形態では、一対のヘッド部材２のうち、一方のヘッド部材２Ａにのみ、マニホールド４及び換装部材５が設けられている。 Among the pair of head members 2, a manifold 4 and a replacement member 5 are disposed in the center portion in the height direction H of one head member 2 A. In the present embodiment, the manifold 4 and the replacement member 5 are provided only on one head member 2 A of the pair of head members 2.

マニホールド４は、ヘッド部材２Ａに形成される本体部１１と、該本体部１１の先端側に隣接配置される調整部１２と、を備えている。換装部材５は、ヘッド部材２Ａにおいてマニホールド４の本体部１１の先端側に隣接して形成される溝部１３内に着脱可能に配設されており、マニホールド４の調整部１２は、該換装部材５に形成されている。 The manifold 4 includes a main body portion 11 formed on the head member 2 A and an adjustment portion 12 disposed adjacent to the distal end side of the main body portion 11. The replacement member 5 is detachably disposed in a groove portion 13 formed adjacent to the distal end side of the main body portion 11 of the manifold 4 in the head member 2A, and the adjustment portion 12 of the manifold 4 is connected to the replacement member 5. Is formed.

マニホールド４の本体部１１は、ヘッド部材２Ａの内面８に開口しているとともに、該内面８から窪まされて形成されている。本体部１１は、長手方向Ｌに長い直方体穴状をなしており、該本体部１１の長手方向Ｌの長さは、スリット３の長手方向Ｌの長さに対応している。 The main body 11 of the manifold 4 is open to the inner surface 8 of the head member 2 A and is formed to be recessed from the inner surface 8. The main body 11 has a rectangular parallelepiped hole shape that is long in the longitudinal direction L, and the length of the main body 11 in the longitudinal direction L corresponds to the length of the slit 3 in the longitudinal direction L.

ヘッド部材２Ａには、外面７に開口してマニホールド４の本体部１１に連通する液供給路１４が形成されている。液供給路１４は、不図示の上記供給ポンプに接続されている。尚、液供給路１４は、塗布工具１の外部に設置された上記供給ポンプとマニホールド４内とを連通可能にヘッド部材２Ａに形成されていればよいことから、その形状や配置は本実施形態で説明したものに限定されない。具体的に、例えば液供給路１４が、他方のヘッド部材２Ｂに形成されて、マニホールド４内に連通していても構わない。 The head member 2 A is formed with a liquid supply path 14 that opens to the outer surface 7 and communicates with the main body 11 of the manifold 4. The liquid supply path 14 is connected to the supply pump (not shown). The liquid supply path 14 only needs to be formed in the head member 2A so that the supply pump installed outside the application tool 1 and the manifold 4 can communicate with each other. It is not limited to what was described in. Specifically, for example, the liquid supply path 14 may be formed in the other head member 2 B and communicated with the inside of the manifold 4.

溝部１３は、ヘッド部材２Ａの内面８に開口しているとともに、長手方向Ｌに沿って延びており、図示の例では、ヘッド部材２Ａを長手方向Ｌに貫通して形成されている。溝部１３の内壁面のうち、先端側（図２における上側）を向く壁面における長手方向Ｌの両端部以外の部位は切り欠かれており、該切り欠き部分を通して、溝部１３内とマニホールド４の本体部１１内とが連通している。 The groove portion 13 is open on the inner surface 8 of the head member 2A and extends along the longitudinal direction L. In the illustrated example, the groove portion 13 is formed through the head member 2A in the longitudinal direction L. Of the inner wall surface of the groove portion 13, portions other than both end portions in the longitudinal direction L on the wall surface facing the front end side (upper side in FIG. 2) are cut out, and the inside of the groove portion 13 and the main body of the manifold 4 are passed through the cutout portions. The inside of the part 11 communicates.

図１において、溝部１３の内壁面のうち、幅方向Ｗの内側（スリット３側）を向く壁面（底面）には、ヘッド部材２Ａをその厚さ方向（塗布工具１の幅方向Ｗ）に貫通する貫通孔１５が形成されている。貫通孔１５は、多段円孔状をなしており、該貫通孔１５の外面７に開口する部分（大径部分）の内径は、溝部１３の前記壁面（底面）に開口する部分（小径部分）の内径よりも大きくなっている。特に図示しないが、貫通孔１５は、ヘッド部材２Ａに長手方向Ｌに間隔をあけて複数穿設されている。 In FIG. 1, among the inner wall surfaces of the groove 13, the head member 2 A is penetrated in the thickness direction (the width direction W of the coating tool 1) through the wall surface (bottom surface) facing the inner side (slit 3 side) in the width direction W. A through-hole 15 is formed. The through hole 15 has a multistage circular hole shape, and the inner diameter of the portion (large diameter portion) that opens to the outer surface 7 of the through hole 15 is the portion (small diameter portion) that opens to the wall surface (bottom surface) of the groove portion 13. It is larger than the inner diameter. Although not particularly illustrated, a plurality of through holes 15 are formed in the head member 2A at intervals in the longitudinal direction L.

換装部材５は、ステンレス鋼等の金属材料からなる。尚、換装部材５は、前記ステンレス鋼等の金属材料に代えて、ステンレス鋼よりも比重が軽い例えばアルミニウムなどの軽金属や、６ナイロンなどの樹脂材料等から形成されていてもよい。 The replacement member 5 is made of a metal material such as stainless steel. The replacement member 5 may be made of a light metal having a specific gravity lower than that of stainless steel, such as aluminum, or a resin material such as 6 nylon, instead of the metal material such as stainless steel.

換装部材５は、図１に示す縦断面視で矩形状をなしており、図２に示すように長手方向Ｌに延びて形成されている。換装部材５は、溝部１３に対応する形状とされており、該溝部１３内に収容可能に形成されている。本実施形態では、溝部１３がヘッド部材２Ａを長手方向Ｌに貫通して形成されているのに対応して、換装部材５は、ヘッド部材２Ａの長手方向Ｌの端面から溝部１３内に挿入可能とされ、また溝部１３内から長手方向Ｌに取り外し可能とされている。 The replacement member 5 has a rectangular shape in a longitudinal sectional view shown in FIG. 1, and is formed to extend in the longitudinal direction L as shown in FIG. The replacement member 5 has a shape corresponding to the groove 13 and is formed so as to be accommodated in the groove 13. In the present embodiment, the replacement member 5 can be inserted into the groove portion 13 from the end surface in the longitudinal direction L of the head member 2A, corresponding to the groove portion 13 being formed through the head member 2A in the longitudinal direction L. In addition, it can be removed in the longitudinal direction L from the inside of the groove 13.

換装部材５において、幅方向Ｗの内側を向く端面と基端側を向く端面との交差部分は、面取り形状に切り欠かれており、この切り欠き部分がマニホールド４の調整部１２とされている。具体的に、換装部材５の調整部１２は、幅方向Ｗの内側（他方のヘッド部材２Ｂ側）に向かうに従い先端側に向けて傾斜するテーパ面１６を有している。 In the replacement member 5, the intersection of the end surface facing the inner side in the width direction W and the end surface facing the base end side is notched in a chamfered shape, and the notched portion serves as the adjusting portion 12 of the manifold 4. . Specifically, the adjustment portion 12 of the replacement member 5 has a tapered surface 16 that is inclined toward the distal end side toward the inner side in the width direction W (the other head member 2B side).

図２において、換装部材５のテーパ面１６は、マニホールド４の本体部１１に臨んでいるとともに、該本体部１１から先端側に向けた深さ（高さ方向Ｈに沿う長さ）が、スリット３が延在する方向（つまり塗布工具１の長手方向Ｌ）に沿って変化するように形成されている。また、これに伴い、マニホールド４の調整部１２からスリット３の開口部（刃先エッジ）までの距離が、該スリット３が延在する方向に沿って変化するように構成されている。 In FIG. 2, the tapered surface 16 of the replacement member 5 faces the main body portion 11 of the manifold 4, and the depth (length along the height direction H) from the main body portion 11 toward the distal end is a slit. 3 is formed so as to change along the extending direction (that is, the longitudinal direction L of the coating tool 1). Accordingly, the distance from the adjustment portion 12 of the manifold 4 to the opening (blade edge) of the slit 3 is changed along the direction in which the slit 3 extends.

本実施形態では、テーパ面１６のうち、長手方向Ｌの両端部における先端側へ向けた深さが、該両端部の間に位置する中間部の前記深さよりも大きくされている。具体的には、テーパ面１６は、長手方向Ｌの両端部から長手方向Ｌの内側（中央部）に向かうに従い漸次先端側へ向けた深さが浅くなるように形成されている。 In this embodiment, the depth toward the front end side at both end portions in the longitudinal direction L of the taper surface 16 is made larger than the depth of the intermediate portion located between the both end portions. Specifically, the taper surface 16 is formed so that the depth from the both end portions in the longitudinal direction L toward the distal end side gradually decreases toward the inner side (center portion) in the longitudinal direction L.

また、これに伴って、マニホールド４の調整部１２のうち、スリット３が延在する方向（長手方向Ｌ）に沿う両端部は、該両端部の間に位置する中間部よりも先端側に配置されている（先端側に向けて窪んでいる）。具体的には、調整部１２からスリット３の開口部までの距離は、長手方向Ｌの両端部における距離Ｄ１が最も小さく、該両端部から長手方向Ｌの内側（中央部）に向かうに従い漸次大きくなっていき、長手方向Ｌの中央部における距離Ｄ２が最大となっている。 Accordingly, both ends of the adjusting portion 12 of the manifold 4 along the direction in which the slit 3 extends (longitudinal direction L) are arranged on the tip side of the intermediate portion located between the both ends. (It is depressed toward the tip side.) Specifically, the distance from the adjustment unit 12 to the opening of the slit 3 is the smallest distance D1 at both ends in the longitudinal direction L, and gradually increases from the both ends toward the inside (center) of the longitudinal direction L. The distance D2 at the center in the longitudinal direction L is the maximum.

図１において、本実施形態では、テーパ面１６は、換装部材５において幅方向Ｗの内側を向く端面から幅方向Ｗの外側へ向けた深さ（幅方向Ｗに沿う長さ）についても、長手方向Ｌに沿って変化するように形成されている。また、これに伴い、マニホールド４の調整部１２における幅方向Ｗの外側へ向けた深さが、長手方向Ｌに沿って変化するように構成されている。 In FIG. 1, in the present embodiment, the tapered surface 16 has a longitudinal length (length along the width direction W) extending from the end surface facing the inner side in the width direction W to the outer side in the width direction W in the replacement member 5. It is formed so as to change along the direction L. Accordingly, the depth of the adjusting portion 12 of the manifold 4 toward the outside in the width direction W is configured to change along the longitudinal direction L.

具体的には、テーパ面１６のうち、長手方向Ｌの両端部における幅方向Ｗの外側へ向けた深さが、該両端部の間に位置する中間部の前記深さよりも大きくされている。図示の例では、テーパ面１６は、長手方向Ｌの両端部から長手方向Ｌの内側（中央部）に向かうに従い漸次幅方向Ｗの外側へ向けた深さが浅くなるように形成されている。 Specifically, in the tapered surface 16, the depth in the width direction W at both ends in the longitudinal direction L is greater than the depth of the intermediate portion located between the both ends. In the illustrated example, the tapered surface 16 is formed so that the depth from the both ends in the longitudinal direction L toward the outside in the width direction W gradually decreases toward the inside (center) in the longitudinal direction L.

また、これに伴って、マニホールド４の調整部１２のうち、長手方向Ｌに沿う両端部は、該両端部の間に位置する中間部よりも幅方向Ｗの外側に配置されている（幅方向Ｗの外側に向けて窪んでいる）。具体的には、調整部１２における幅方向Ｗの外側へ向けた深さは、長手方向Ｌの両端部において最大とされ、該両端部から長手方向Ｌの内側（中央部）に向かうに従い漸次小さくなっていき、長手方向Ｌの中央部において最も小さくされている。 Accordingly, both end portions along the longitudinal direction L of the adjustment portion 12 of the manifold 4 are disposed outside the intermediate portion located between the both end portions in the width direction W (width direction). It is recessed toward the outside of W). Specifically, the depth toward the outside in the width direction W in the adjustment unit 12 is maximized at both end portions in the longitudinal direction L, and gradually decreases from the both end portions toward the inside (center portion) in the longitudinal direction L. It becomes the smallest in the central part in the longitudinal direction L.

また、換装部材５には、その幅方向Ｗの外側を向く端面に開口するとともに幅方向Ｗに沿って延びるねじ穴１７が形成されている。ねじ穴１７は、ヘッド部材２Ａの貫通孔１５に対応する位置にそれぞれ穿設されており、換装部材５における幅方向Ｗの外側を向く端面に開口する一方で、該換装部材５における幅方向Ｗの内側を向く端面には開口されない止め穴となっている。ねじ穴１７には、雌ねじ加工が施されている。 In addition, the replacement member 5 is formed with a screw hole 17 that opens in an end surface facing the outside in the width direction W and extends along the width direction W. The screw holes 17 are respectively formed at positions corresponding to the through holes 15 of the head member 2 A, and open to the end face of the replacement member 5 facing the outside in the width direction W, while the width direction W of the replacement member 5. It is a stop hole that is not opened on the end face facing the inside. The screw hole 17 is subjected to female thread processing.

ヘッド部材２Ａ及び換装部材５は、貫通孔１５に挿通したボルト１８をねじ穴１７に螺着することによって、互いに固定されている。本実施形態では、ボルト１８の頭部（雄ねじ加工が施されたねじ部よりも大径の部分）は、貫通孔１５の外面７に開口する大径部分内に収容されている。 The head member 2 A and the replacement member 5 are fixed to each other by screwing bolts 18 inserted through the through holes 15 into the screw holes 17. In the present embodiment, the head portion of the bolt 18 (portion having a larger diameter than the threaded portion subjected to male screw processing) is accommodated in a large diameter portion that opens to the outer surface 7 of the through hole 15.

また、ヘッド部材２Ａの内面８において、マニホールド４の基端側に位置する部位には、長手方向Ｌに間隔をあけて複数のねじ穴１９が開口している。これらのねじ穴１９は、幅方向Ｗに延びて穿設されており、図示の例では、長手方向Ｌに配列されている。ねじ穴１９は、ヘッド部材２Ａの内面８のみに開口された止め穴となっている。ねじ穴１９には、雌ねじ加工が施されている。 In addition, a plurality of screw holes 19 are opened at intervals in the longitudinal direction L at a portion of the inner surface 8 of the head member 2 A located on the proximal end side of the manifold 4. These screw holes 19 extend in the width direction W and are arranged in the longitudinal direction L in the illustrated example. The screw hole 19 is a stop hole opened only in the inner surface 8 of the head member 2A. The screw hole 19 is subjected to female threading.

一対のヘッド部材２のうち、他方のヘッド部材２Ｂには、該ヘッド部材２Ｂをその厚さ方向（塗布工具１の幅方向Ｗ）に貫通する貫通孔２０が形成されている。貫通孔２０は、多段円孔状をなしており、該貫通孔２０においてヘッド部材２Ｂの外面７に開口する部分（大径部分）の内径は、該ヘッド部材２Ｂの内面８に開口する部分（小径部分）の内径よりも大きくなっている。貫通孔２０は、ヘッド部材２Ａのねじ穴１９に対応する位置に配置されているとともに、ヘッド部材２Ｂに長手方向Ｌに間隔をあけて複数穿設されている。 Of the pair of head members 2, the other head member 2 B is formed with a through hole 20 that penetrates the head member 2 B in the thickness direction (width direction W of the coating tool 1). The through hole 20 has a multi-stage circular hole shape, and the inner diameter of the portion (large diameter portion) that opens to the outer surface 7 of the head member 2B in the through hole 20 is the portion that opens to the inner surface 8 of the head member 2B ( It is larger than the inner diameter of the small diameter part. The through holes 20 are disposed at positions corresponding to the screw holes 19 of the head member 2A, and a plurality of through holes 20 are formed in the head member 2B at intervals in the longitudinal direction L.

ヘッド部材２Ａ及びヘッド部材２Ｂは、貫通孔２０に挿通したボルト２１をねじ穴１９に螺着することによって、互いに固定されている。本実施形態では、ボルト２１の頭部（雄ねじ加工が施されたねじ部よりも大径の部分）は、貫通孔２０の外面７に開口する大径部分内に収容されている。 The head member 2 A and the head member 2 B are fixed to each other by screwing a bolt 21 inserted through the through hole 20 into the screw hole 19. In the present embodiment, the head portion of the bolt 21 (the portion having a larger diameter than the threaded portion subjected to male screw processing) is accommodated in the large diameter portion that opens to the outer surface 7 of the through hole 20.

以上説明した本実施形態の塗布工具１によれば、マニホールド４が本体部１１と調整部１２とを備えており、本体部１１はヘッド部材２（２Ａ）に形成されている一方、調整部１２は該ヘッド部材２に着脱可能に装着された換装部材５に形成されている。この構成により、マニホールド４のうちヘッド部材２のスリット３開口部（刃先エッジ）に近く、塗布精度に影響しやすい調整部１２の形状を、換装部材５を交換することで容易に、かつ迅速に変更することができる。 According to the coating tool 1 of the present embodiment described above, the manifold 4 includes the main body 11 and the adjustment unit 12, and the main body 11 is formed on the head member 2 (2A), while the adjustment unit 12 is provided. Is formed on a replacement member 5 detachably mounted on the head member 2. With this configuration, the shape of the adjusting unit 12 that is close to the slit 3 opening (blade edge) of the head member 2 in the manifold 4 and easily affects the coating accuracy can be easily and quickly replaced by replacing the replacement member 5. Can be changed.

具体的に、本実施形態によれば、塗布液に応じてマニホールド４形状を変更するにあたり、従来のようにヘッド部材を切削等により加工する必要はなく、ヘッド部材２に装着された換装部材５を取り外すとともに、前記塗布液に適した調整部１２の形状を有する他の換装部材５に交換することで、簡便に対応することができる。従って、例えば中高粘度の塗布液を用いて塗工するような場合であっても、被塗布物に塗布される塗布液の膜（層）厚を、スリット３が延在する方向（塗布工具１の長手方向Ｌ）に沿って簡単に均一にすることができる。
そして、この構成によれば、性質の似た異なる塗布液の塗工に同一のヘッド部材２を用いることが比較的簡単に行え、高価なヘッド部材２を種々の塗布液に応じて多数（複数種類）用意しなければならないという事態を回避しやすい。 Specifically, according to the present embodiment, when changing the shape of the manifold 4 according to the coating liquid, there is no need to process the head member by cutting or the like as in the prior art, and the replacement member 5 attached to the head member 2. It is possible to easily cope with the problem by replacing the other replacement member 5 having the shape of the adjustment unit 12 suitable for the coating liquid. Therefore, for example, even when coating is performed using a medium-high viscosity coating liquid, the thickness of the coating liquid (layer) applied to the object to be coated is set in the direction in which the slit 3 extends (the coating tool 1). Can be easily made uniform along the longitudinal direction L).
According to this configuration, it is relatively easy to use the same head member 2 for coating different coating liquids having similar properties, and a large number of expensive head members 2 can be used according to various coating liquids (multiple (multiple). Kind) It is easy to avoid the situation that you have to prepare.

さらに、換装部材５には、マニホールド４全体のうち調整部１２の形状のみが付与されていればよいことから、該換装部材５の外形を小さくできる。特に、本実施形態のように、調整部１２における塗布液の容量が本体部１１における塗布液の容量に比べて十分に小さく設定されている場合には、換装部材５の小型化がより簡単に行える。従って、塗布液に合わせて複数種類の換装部材５を用意する場合であっても、部品の維持管理や交換作業時の取り扱いが容易である。 Furthermore, since only the shape of the adjustment portion 12 of the entire manifold 4 needs to be given to the replacement member 5, the outer shape of the replacement member 5 can be reduced. In particular, when the volume of the coating liquid in the adjustment unit 12 is set to be sufficiently smaller than the volume of the coating liquid in the main body unit 11 as in the present embodiment, the replacement member 5 can be more easily downsized. Yes. Therefore, even when a plurality of types of replacement members 5 are prepared in accordance with the coating liquid, the parts can be easily maintained and handled during replacement work.

また、換装部材５は、製造時の加工精度が被塗布物に塗布液を塗布するヘッド部材２ほどには要求されないため、安価に製造できる。また、ヘッド部材２のような剛性も必要とされないため、例えば、換装部材５として重量（比重）が軽く取り扱いやすい材料（アルミニウムや樹脂材料等）を選択することも可能であり、この場合、換装部材５の交換作業をより簡便に行うことができる。 Further, the replacement member 5 can be manufactured at low cost because the processing accuracy at the time of manufacture is not required as much as the head member 2 that applies the coating liquid to the object to be coated. Further, since the rigidity as in the head member 2 is not required, for example, a material (aluminum, resin material, etc.) having a light weight (specific gravity) and easy to handle can be selected as the replacement member 5. The replacement work of the member 5 can be performed more easily.

このように、本実施形態の塗布工具１によれば、塗布液に応じてマニホールド４形状を容易に変更でき、これにより塗布精度を安定して高めることができ、かつ、コストを削減できる。そして、低粘度から中高粘度まで幅広い塗布液の塗工に容易にかつ廉価に対応できる。 As described above, according to the application tool 1 of the present embodiment, the shape of the manifold 4 can be easily changed according to the application liquid, whereby the application accuracy can be stably increased and the cost can be reduced. And it can respond easily and inexpensively to coating of a wide range of coating solutions from low viscosity to medium and high viscosity.

また、マニホールド４の調整部１２からスリット３の開口部までの距離が、該スリット３が延在する方向（長手方向Ｌ）に沿って変化するように構成されているので、下記の効果を奏する。
本実施形態によれば、マニホールド４の調整部１２からスリット３の開口部までの距離に応じて、該スリット３から被塗布物に塗布される塗布液の膜厚が調整される。具体的に、スリット３の延在方向において、塗布液の膜厚が薄くなりやすい箇所（例えばスリット３の延在方向に沿う両端部など）については、調整部１２からスリット３の開口部までの距離を短く設定することで、塗布液が吐出されやすくなるとともに、膜厚を所定範囲に確保しやすくなる。また、塗布液の膜厚が厚くなりやすい箇所（例えばスリット３の延在方向に沿う中央部など）については、調整部１２からスリット３の開口部までの距離を長く設定することで、塗布液が吐出されにくくなるとともに、膜厚を所定範囲に確保しやすくなる。 Moreover, since the distance from the adjustment part 12 of the manifold 4 to the opening part of the slit 3 changes along the direction (longitudinal direction L) in which the slit 3 extends, the following effects are produced. .
According to the present embodiment, the film thickness of the coating liquid applied from the slit 3 to the coating object is adjusted according to the distance from the adjustment unit 12 of the manifold 4 to the opening of the slit 3. Specifically, in the extending direction of the slit 3, the portion of the coating liquid that tends to be thin (for example, both end portions along the extending direction of the slit 3) is from the adjusting unit 12 to the opening of the slit 3. By setting the distance short, the coating liquid can be easily discharged and the film thickness can be easily secured within a predetermined range. Moreover, about the location (for example, the center part in alignment with the extension direction of the slit 3 etc.) where the film thickness of the coating liquid tends to increase, the coating liquid can be set by setting the distance from the adjustment unit 12 to the opening of the slit 3 long. Becomes difficult to be discharged, and the film thickness is easily secured within a predetermined range.

すなわち、上記構成によれば、塗布液の性質（粘度など）や塗工条件に応じて、スリット３の延在する方向に沿う各部位において、調整部１２からスリット３の開口部までの距離を適宜設定することにより、前述した塗布精度を安定して高めるという効果を簡単に、かつ顕著に得ることができるのである。 That is, according to the said structure, according to the property (viscosity etc.) of coating liquid, and coating conditions, in each site | part along the direction where the slit 3 is extended, the distance from the adjustment part 12 to the opening part of the slit 3 is set. By setting appropriately, the above-described effect of stably increasing the coating accuracy can be obtained easily and significantly.

また、マニホールド４の調整部１２のうち、スリット３が延在する方向に沿う両端部が、該両端部の間に位置する中間部よりも先端側に配置されているので、下記の効果を奏する。
一般に、例えば、中高粘度の塗布液を用いて塗工する際には、低粘度の塗布液を用いる場合に比べて、マニホールドの内圧がばらつきやすくなるとともに、スリットの開口部のうち、該スリットの延在する方向の両端部から被塗布物に塗布される塗布液の膜厚が、前記両端部の間に位置する中間部から塗布される塗布液の膜厚よりも薄くなりがちである。
従って、本実施形態の上記構成とすることにより、スリット３の開口部のうち、特に該スリット３の両端部から吐出される塗布液の膜厚が十分に確保されて、被塗布物に対して塗布液がより均一に塗布されることとなる。 Moreover, since the both ends along the direction where the slit 3 extends are arrange | positioned among the adjustment parts 12 of the manifold 4 in the front end side rather than the intermediate part located between these both ends, there exists the following effect. .
In general, for example, when coating with a medium-high viscosity coating liquid, the internal pressure of the manifold is more likely to vary than in the case of using a low-viscosity coating liquid, and among the slit openings, the slit The film thickness of the coating liquid applied to the object to be coated from both ends in the extending direction tends to be thinner than the film thickness of the coating liquid applied from the intermediate part located between the both ends.
Therefore, by adopting the above-described configuration of the present embodiment, a sufficient film thickness of the coating liquid discharged from both ends of the slit 3 among the openings of the slit 3 is sufficiently secured, so The coating solution is applied more uniformly.

また、隣り合う一対のヘッド部材２同士のうち、一方のヘッド部材２Ａに装着された換装部材５の調整部１２が、他方のヘッド部材２Ｂ側（幅方向Ｗの内側）に向かうに従い先端側に向けて傾斜するテーパ面１６を有しているので、下記の効果を奏する。
すなわち、この構成によれば、マニホールド４の本体部１１から調整部１２を通ってスリット３に供給される塗布液が、該調整部１２において乱流を生じるようなことが抑制される。これにより、調整部１２の形状に応じて、塗布液がスリット３の延在方向に沿う各部位において狙った膜厚の範囲内となるように吐出されやすくなって、塗布精度をさらに安定的に高めることができる。 Moreover, the adjustment part 12 of the replacement | exchange member 5 with which one head member 2A was mounted | worn among a pair of adjacent head members 2 goes to the front end side as it goes to the other head member 2B side (inner side of the width direction W). Since it has the taper surface 16 which inclines toward, there exists the following effect.
That is, according to this configuration, the application liquid supplied from the main body portion 11 of the manifold 4 through the adjustment portion 12 to the slit 3 is suppressed from causing turbulent flow in the adjustment portion 12. Thereby, according to the shape of the adjustment part 12, it becomes easy to discharge a coating liquid so that it may become in the range of the target film thickness in each site | part along the extension direction of the slit 3, and coating accuracy is further stabilized. Can be increased.
