この発明はシームレス缶のチャイム部の塗装方法、特に
ロールによる塗装方法およびそのための塗装装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of coating a chime portion of a seamless can, particularly to a coating method using a roll and a coating apparatus therefor.
（従来技術）
スチール製シームレス（ＳＤＩ）缶は発錆防止のため保
護塗料により完全に塗装されなければならない、しかし
、スリーピース缶と異なり、成形前に塗装・印刷を行う
こととは固層で、缶成形工程の終了後に行われる。その
工程は一般には以下のようになる。(Prior Art) Seamless steel (SDI) cans must be completely coated with a protective coating to prevent rusting, but unlike three-piece cans, painting and printing before forming is a solid layer; This is done after the can forming process is completed. The process is generally as follows.
ボディメーカーによる成形→トリミング→洗浄→外面の
塗装・印刷→缶底接地部のロールコート−ビンオーブン
による乾燥焼付け→内面スプレー及びドーム部外面スプ

装装置等のよごれ、それによる工程以上の多発、塗膜の
不均一、オーバースプレィによる塗料の無駄等の問題を
有するものであった。Molding by the body maker → Trimming → Cleaning → Painting and printing on the outside → Roll coating on the bottom of the can – Dry baking in a bottle oven → Spraying on the inside and outside of the dome → Drying baking in an oven This spray painting is done by spraying. This has caused problems such as staining of guides, coating equipment, etc. due to scattering of paint, resulting in frequent over-processing, uneven coating, and waste of paint due to overspray.
塗装ロールによるロールコート方式は、スプレィ方式に
よって生じる工程異常が皆無となり、塗膜の均一性の向
上、塗料使用量の減少によるコストの低下等の有利性を
持っている。The roll coating method using a paint roll has advantages such as eliminating process abnormalities caused by the spray method, improving the uniformity of the coating film, and lowering costs by reducing the amount of paint used.
しかし、ＳＤＩスタッカプル缶においては、缶朋下部は
テーパ一部を有し、このテーパ一部を経てドーム部に接

公昭５８−５７１２号、特開昭５８−１４９６９号、同
昭５８−２０５５５９号等の公報にその例が見られる。However, in SDI stacker-pull cans, the lower part of the can has a tapered part and is connected to the dome part through this taper part, but an attempt has also been proposed to paint this taper part using a roll coating method. Examples of such methods can be found in Japanese Patent Publications No. 58-5712, Japanese Patent Application Laid-Open No. 14969-1982, and Japanese Patent Application Laid-Open No. 58-205559.
しかし、前２者はコートロールは缶や他のロールとは傾
いた回転軸を持ち、塗装装置の機構が複雑となり、後者
は異形ロールを用いるため、塗膜の均一性を保つことが
難しいという問題を残していた。However, with the former two, the coat roll has a rotation axis that is tilted compared to cans and other rolls, making the mechanism of the coating equipment complicated, and with the latter, it is difficult to maintain uniformity of the coating because it uses irregularly shaped rolls. I was left with a problem.

。９はボトムガイドである。(Means for solving the problem) In this invention, the can 1 to be painted is shown in FIGS. 1 and 2.
As shown in the figure, the cans are transferred by a belt 3 with a V-guide and a fixed upper guide 4 whose contact surface with the can is made of a material with a high coefficient of friction such as urethane rubber. An applicator roll 5 extending in the transport direction is disposed along this transport path, and a paint pan 7 is provided by a metering roll 6.
The trim portion of can 1, to which paint is supplied from, is brought into contact with the trim guide 8 and its chime portion 2 is brought into contact with the applicator roll 5, whereby positioning in the direction perpendicular to the transport direction is performed and the chime portion is painted. be exposed. 9 is a bottom guide.
（実施例）
以下４図面を参照してこの発明の実施例を詳細に説明す
る。(Example) Examples of the present invention will be described in detail below with reference to four drawings.
第１図において、缶１は平ベルト３によって移送される

第２図矢印のように回転する。このとき、チャイム部２

がストレートな円筒状であると缶がロールから離れる瞬
間にローラーのゴムの弾性で塗料がはじき飛ばされ、そ
の端部の痕跡が塗膜上に残ってしまう、このため。In FIG. 1, a can 1 is conveyed by a flat belt 3, but its upper end contacts an upper guide 4 and is stopped, so that it rotates as indicated by the arrow in FIG. At this time, chime section 2
is in contact with the applicator roll 5, so the chime part 2 is painted, but if both ends of the applicator roll 5 are straight cylindrical, the paint will be blown off by the elasticity of the roller's rubber the moment the can leaves the roll. , because of this, traces of its edges remain on the coating.
アプリケーターロール５は第３図に示すように両端をテ
ーパー状にし、端部と缶１との接触を防止する。このた
めのテーパーは以下のように形成される。The applicator roll 5 has both ends tapered to prevent contact between the ends and the can 1, as shown in FIG. The taper for this purpose is formed as follows.
第４図を参照して１パスで塗装するためには、アプリケ
ーターロール５はＡＢだけの凹みを生じなければならな
い、チャイム部２の幅を１０ＩＩ１１．アプリケーター
ロール５の半径を５０ｍｍとすれば。Referring to FIG. 4, in order to paint in one pass, the applicator roll 5 must have a recess of AB, and the width of the chime portion 2 must be 10II11. If the radius of the applicator roll 5 is 50 mm.
この凹みは、
Ａ Ｂ ＝ ＯＢ −ＯＡ ＝５０− ｆｉ＊０．２５
となり、最低Ｑ、２５ｍ菖逃せば良いこととなる。This depression is AB = OB - OA = 50 - fi * 0.25
Therefore, it is enough to miss the minimum Q by 25m.
安全を見て、０．５＋＋−の逃げを１１５０のテーパー
で作れば、テーパー角θは約０．５７°となる。Considering safety, if we create a relief of 0.5++- with a taper of 1150, the taper angle θ will be about 0.57°.
アプリケーターロール５の回転方向は第１図矢印のよう

こととなり、摩擦を増大する。また、胴壁部への塗料の
たれやドーム部への塗料の流れ込みを防止する点からも
この方向が望ましい。The direction of rotation of the applicator roll 5 is preferably from the chime part 2 to the bottom part as shown by the arrow in Figure 1.The trim guide 8 on the trim side is made of tempered glass in consideration of slipperiness and durability. However, if the direction of rotation of the applicator roll 5 is reversed, the can 1 will be pressed against the trim guide 8 by the applicator roll 5, increasing friction. This direction is also desirable from the viewpoint of preventing paint from dripping onto the barrel wall or flowing into the dome.
コーティングを１バスで°行うことは容易であるために

る。It is desirable to coach the chime section 2 in two stages, that is, as shown in FIGS. 5(a) and 5(b).
The first coater coats the part a in FIG. 6, and then the second coater coats the part b with slight overlap.

ものである。(Effects of the Invention) As described above, this invention roll coats the charm part of a seamless can, so there are no problems caused by spray coating, and the coating applicator roll is approximately parallel to the direction of transport of one can. Since it extends in a straight line, it is easy to use the machine barrel as a coating device, and it is possible to stably obtain a uniform coating film. Furthermore, by selecting the direction of rotation of the rolls, the durability of the coating device can be increased, and significant effects can be achieved, such as preventing paint from dripping or flowing to unnecessary areas.
