Abstract

複数コンポーネント材料のためのミキサを改良し、混合し難い材料にも対応できるようにする。
【解決手段】
複数コンポーネントの計量及び混合のためのシステム（１２）において、従来のエアーレスチップ（１８）がスタティックミキサ（１６）の直近の下流側に位置する流体ライン（２０）内に直列配置されている。スプレーチップ（１８）の両端における１０から３０バール（１０×１０５から３０×１０５ Ｐａ）の圧力低下によって、水性及びその他の混合し難い複数のコンポーネント材料の混合性が向上される。Improve mixers for multi-component materials to accommodate materials that are difficult to mix.
[Solution]
In a system (12) for multi-component metering and mixing, a conventional airless tip (18) is placed in series in a fluid line (20) located immediately downstream of a static mixer (16). A pressure drop of 10 to 30 bar (10 × 10 5 to 30 × 10 5 Pa) at both ends of the spray tip (18) improves the mixing of the aqueous and other hard-to-mix component materials.

背景技術
環境上の理由や処理品質上の理由から、近年、複数コンポーネントの塗料その他の材料が増加普及してきている。多くの製造業者が種々の基材に適用するための複数のコンポーネントを計量及び混合するための装置を製造している。特に、水性材料はそれらの材料の混合及びブレンドに関して特別な問題点を抱えている。グラコ（Ｇｒａｃｏ）の「ＰＲＥＣＩＳＩＯＮＭＩＸ」という商標名の複数コンポーネント用の装置などのデバイスはそのような材料を混合するために産業界において数多く採用されてきたけれども、最終混合に際しての扱い難さが一部で判明している。ベイヤー（Ｂａｙｅｒ）によって製造されているジェット分散デバイスはそのような材料の混合が可能であることが実証されているけれども、幾分複雑で、フラッシュが比較的困難である。
【０００３】
発明の開示
したがって、この発明の目的は、混合し難いコンポーネントを使用した場合であっても、均一に混合された材料を生成することのできるミキサを開発することである。そのために、上記の「ＰＲＥＣＩＳＩＯＮＭＩＸ」などの典型的な連続計量デバイスは、混合を達成するために、スタティックミキサの上流側に配置された積算器を使用してしている。この発明においては、スタティックミキサのアウトレットはスプレーガンその他のアプリケーションデバイスへ続くライン上に直列配置された従来のエアーレスチップに接続されている。エアーレスチップの寸法は、１０から３０バール（１０×１０５から３０×１０５ Ｐａ）の圧力低下がそのチップを通じて維持され、適正な圧力低下が得られるように設定されている。その一例として、５ｍｍの流体ライン内において０．８ｍｍのチップが使用されている。

2. Description of the Related Art In recent years, paints and other materials of a plurality of components have been increasing and spreading for environmental reasons and processing quality reasons. Many manufacturers make devices for metering and mixing multiple components for application to various substrates. In particular, aqueous materials have particular problems with mixing and blending those materials. Although devices such as Graco's "PrecisionMIX" multi-component device have been widely employed in the industry to mix such materials, there are some difficulties in final mixing. Is known. Although jet dispersion devices manufactured by Bayer have demonstrated the ability to mix such materials, they are somewhat complex and relatively difficult to flush.
[0003]
DISCLOSURE OF THE INVENTION Accordingly, it is an object of the present invention to develop a mixer that can produce a homogeneously mixed material, even when using components that are difficult to mix. To that end, typical continuous metering devices, such as the above "PRECISIONMIX", use an integrator located upstream of a static mixer to achieve mixing. In the present invention, the outlet of the static mixer is connected to a conventional airless tip which is arranged in series on a line leading to a spray gun or other application device. The dimensions of the airless tip are such that a pressure drop of 10 to 30 bar (10 × 10 5 to 30 × 10 5 Pa) is maintained through the tip and a proper pressure drop is obtained. As an example, a 0.8 mm tip is used in a 5 mm fluid line.
[0004]
These and other objects and advantages of the present invention will become more fully apparent from the following description made with reference to the accompanying drawings. In the accompanying drawings, the same or similar members are denoted by the same reference numerals throughout.
[0005]
DETAILED DESCRIPTION OF THE INVENTION The present invention, designated by reference numeral 10, includes a multi-component mixer 12. This mixer 12 has an integrator 14 and a static mixer 16 arranged behind it. The outlet 16 a of the static mixer 16 is connected to the spray tip 18. Spray tip 18 is a conventional airless spray tip and is manufactured by Graco, Inc. and many other manufacturers. The airless spray tip 18, on the other hand, is connected to a fluid line 20. In addition, the fluid line, on the other hand, is connected to an application device such as a spray gun.
[0006]
Various changes and modifications may be made to the multi-component material mixer of the present invention without departing from the spirit and scope of the invention. The spirit and scope of the invention is limited by the appended claims.
