It is possible to deal with various coating conditions, and the intermediate part 22 to be prepared is smaller than the whole of the other (lower) part 7, and thus when preparing a plurality of conventional large other parts Compared to the above, manufacturing cost and storage cost can be reduced.

前記他方（下方）の分割部７は、図５及び図６に示す如く、本例では保持部２１の挿着用凹部２１ｂの底面と挿着するマニホールド形成用中間部２２との間に中間部用離接調節板２３を介装して、一方の分割部５に対して中間部２２を離接調節することで、塗工液流路１３の上流側となるマニホールド１０の深さ寸法を変更できるようにしてある。中間部用離接調節板２３は、ボルト１８用のボルト挿通孔２３ａ及びボルト１６用のボルト挿通孔２３ｂ（図６及び図７（Ｃ）参照）が穿設されている。他方（下方）の分割部７は、図５及び図６に示す如く、本例では挿着したマニホールド形成用中間部２２と一方（上方）の分割部５との境界部分に埋込み板２４を介装して、マニホールド１０及び塗工液流路１１以外の隙間を埋めて不要な隙間を生じさせないようにしてある。これら挿着用凹部２１ｂ、マニホールド形成用中間部２２、中間部用離接調節板２３及び埋込み板２４は、マニホールド形成用中間部２２の厚み寸法Ｔ１と、中間部用離接調節板２３の板厚み寸法Ｔ２と、埋込み板２４の板厚み寸法Ｔ３との総和が、挿着用凹部２１ｂの深さ寸法Ｄ（図６参照）となるようにしてある。中間部用離接調節板２３及び埋込み板２４は、組み合わせる板厚み寸法Ｔ２（Ｔ３）の異なる複数組みが予め準備され、組み合わせを変更することで、塗工条件に適した調節塗工液流路１１の上流側１１ａの厚み寸法及びマニホールド１０の深み寸法を得ることができるようになる。埋込み板２４は、図７（Ｅ）に示す如く、ボルト１６用のボルト挿通孔２４ａが穿設されていると共に、中間部２２（同図（Ｃ）参照）に形成したマニホールド用凹部１０ａの開口周縁部１０ｂに隣接する周縁部２４ｂの形状が、該開口周縁部１０ｂと同一形状となっている。 As shown in FIGS. 5 and 6, the other (lower) divided portion 7 is used for the intermediate portion between the bottom surface of the insertion recess 21 b of the holding portion 21 and the manifold forming intermediate portion 22 to be inserted. The depth dimension of the manifold 10 on the upstream side of the coating liquid channel 13 can be changed by adjusting the separation / contact of the intermediate portion 22 with respect to the one divided portion 5 with the separation / contact adjustment plate 23 interposed therebetween. It is like that. The intermediate portion separation / attachment adjusting plate 23 has a bolt insertion hole 23a for the bolt 18 and a bolt insertion hole 23b for the bolt 16 (see FIGS. 6 and 7C). As shown in FIGS. 5 and 6, the other (lower) dividing portion 7 has an embedded plate 24 at the boundary portion between the manifold forming intermediate portion 22 inserted and the one (upper) dividing portion 5 in this example. The gaps other than the manifold 10 and the coating liquid flow path 11 are filled so as not to generate unnecessary gaps. The insertion recess 21b, the manifold forming intermediate portion 22, the intermediate portion separation / adjustment adjustment plate 23, and the embedding plate 24 have a thickness dimension T1 of the manifold formation intermediate portion 22 and a plate thickness of the intermediate portion separation / adjustment adjustment plate 23. The sum of the dimension T2 and the plate thickness dimension T3 of the embedded plate 24 is set to the depth dimension D (see FIG. 6) of the insertion recess 21b. The intermediate part separation / adjustment adjusting plate 23 and the embedding plate 24 are prepared in advance with a plurality of sets having different plate thickness dimensions T2 (T3) to be combined, and by changing the combination, an adjusted coating liquid flow path suitable for coating conditions 11, the thickness dimension of the upstream side 11 a and the depth dimension of the manifold 10 can be obtained. As shown in FIG. 7E, the embedded plate 24 is provided with a bolt insertion hole 24a for the bolt 16, and an opening of the manifold recess 10a formed in the intermediate portion 22 (see FIG. 7C). The shape of the peripheral edge 24b adjacent to the peripheral edge 10b is the same as that of the opening peripheral edge 10b.

Will be able to.

本発明塗工装置１は、図６に示す如く、本例では他方（下方）の分割部７の保持部２１及び一方（上方）の分割部５の本体部６の合わせ面６ａ，２１ｅの突き合わせ部分間に流路厚み調節板２５を介装して、両者を複数本のボルト１６，１７で接合してある。流路厚み調節板２５は、リップ部１４，１５の間まで延設して、吐出口１2 の左右両側を形成してある。本発明塗工装置１は、他方（下方）の分割部７の保持部２１と（上方）の分割部５の本体部６の上記突き合わせ部分間に流路厚み調節板２５を介装せずに両者２１，６を合わせたときに、塗工液流路１１の下流側１１ｂの厚みがゼロ（保持部２１の合わせ面２１ｅと本体部６の合わせ面６ａとが密着する状態）となようにしてあり、塗工液流路１１の下流側１１ｂの厚み寸法を流路厚み調節板２５の板厚み寸法で決定するようにしてある。各種塗工条件に対応させるために、流路厚み調節板２５は、板厚みＴ４の異なる複数枚が予め準備され、塗工条件に適したものを選択しすることで、塗工液流路１１の下流側１１ｂ及びマニホールド１０の厚み寸法を調節することができる。なお、マニホールド１０は、その厚み寸法が塗工液流路１１の下流側１１ｂの厚み寸法より非常に大きいため、流路厚み調節板２５の板厚みＴ４で変化する割合が塗工液流路１１の下流側１１ｂに比べて非常に小さくなり、流路厚み調節板２５の板厚みＴ４の変化による影響を無視できるときがある。流路厚み調節板２５は、図８（Ｂ）に示す如く、ボルト１７用のボルト挿通孔２５ｃ及びボルト１６用のボルト挿通孔２５ａが穿設されていると共に、中間部２２（同図（Ａ）及び図７（Ｄ）参照）に形成したマニホールド用凹部１０ａの開口周縁部１０ｂに隣接する周縁部２５ｂの形状が、該開口周縁部１０ｂと同一形状となっている。更に、前記埋込み板２４を用いる場合には、流路厚み調節板２５は、図８に示す如く、中間部２２に形成したマニホールド用凹部１０ａの開口周縁部１０ｂに隣接する周縁部２５ｂの形状を、該開口周縁部１０ｂと同一形状とし、埋込み板２４に重ね合わすことができる形状となっており、埋込み板２４との間に不要な空間（塗工液が滞留するデッド空間）を形成させることなく、安定した塗工状態の維持を図ることができるようにしてある。
As shown in FIG. 6, the coating apparatus 1 of the present invention, in this example, abuts the holding surfaces 21 of the other (lower) dividing portion 7 and the mating surfaces 6 a and 21 e of the main body 6 of one (upper) dividing portion 5. The flow path thickness adjusting plate 25 is interposed between the parts, and both are joined by a plurality of bolts 16 and 17. The channel thickness adjusting plate 25 extends between the lip portions 14 and 15 to form both the left and right sides of the discharge port 12. The coating apparatus 1 of the present invention is configured such that the flow path thickness adjusting plate 25 is not interposed between the abutting portions of the holding portion 21 of the other (lower) dividing portion 7 and the main body portion 6 of the (upper) dividing portion 5. When both 21 and 6 are combined, the thickness of the downstream side 11b of the coating liquid flow path 11 is zero (the state where the mating surface 21e of the holding part 21 and the mating surface 6a of the main body part 6 are in close contact). The thickness dimension of the downstream side 11b of the coating liquid channel 11 is determined by the plate thickness dimension of the channel thickness adjusting plate 25. In order to correspond to various coating conditions, the flow path thickness adjusting plate 25 is prepared in advance with a plurality of sheets having different plate thicknesses T4, and by selecting the one suitable for the coating conditions, the coating liquid flow path 11 is selected. The thickness dimension of the downstream side 11b and the manifold 10 can be adjusted. In addition, since the thickness dimension of the manifold 10 is much larger than the thickness dimension of the downstream side 11b of the coating liquid flow path 11, the ratio which changes with plate | board thickness T4 of the flow path thickness adjustment board 25 is the coating liquid flow path 11. There is a case where the influence of the change in the plate thickness T4 of the flow path thickness adjusting plate 25 can be ignored. As shown in FIG. 8B, the flow path thickness adjusting plate 25 has a bolt insertion hole 25c for the bolt 17 and a bolt insertion hole 25a for the bolt 16, and an intermediate portion 22 (FIG. 8A). ) And the shape of the peripheral edge portion 25b adjacent to the opening peripheral edge portion 10b of the manifold recess 10a formed in FIG. 7D is the same shape as the opening peripheral edge portion 10b. Further, when the embedded plate 24 is used, the flow path thickness adjusting plate 25 has a shape of a peripheral portion 25b adjacent to the opening peripheral portion 10b of the manifold recess 10a formed in the intermediate portion 22, as shown in FIG. The opening peripheral edge portion 10b has the same shape and can be superimposed on the embedded plate 24, and an unnecessary space (dead space in which the coating liquid stays) is formed between the embedded plate 24 and the embedded plate 24. In this way, it is possible to maintain a stable coating state.
