Description

本発明は容器中の塗料等の攪拌装置に関する。 The present invention relates to an agitation device for a paint in a container.

角缶型容器や円筒型容器単位で販売されている塗料を使用する場合には、容器内の塗料をよく攪拌する必要がある。しかしながら、塗料の注ぎ口は直径５０ｍｍ程度の小さなものが多く、その注ぎ口から棒などを差し込んで塗料を攪拌しようとしても十分に攪拌できない課題を抱えていた。このため、容器の上面を全面切り取るなどすることにより大きく開口して、棒でかき回したり、先端にプロペラを備えた攪拌装置で攪拌したりすることが一般的である。攪拌装置に関しては、特開平２００１−３５３４３３（特許文献１）、特開平５−１１５７６５（特許文献２）、特開平７−２３２７４０（特許文献３）などで示されている。
特開２００１−３５３４３３特開平５−１１５７６５特開平７−２３２７４０ When using paint sold in units of square cans or cylindrical containers, it is necessary to stir the paint in the container well. However, many paint spouts have a diameter of about 50 mm, and even if a stick is inserted through the spout to stir the paint, there is a problem that the paint cannot be sufficiently stirred. For this reason, it is common to open a large opening by, for example, cutting the entire upper surface of the container and to stir it with a stick or to stir it with a stirrer equipped with a propeller at the tip. With respect to the stirring device, JP-A-2001-353433 (Patent Document 1), JP-A-5-115765 (Patent Document 2), JP-A-7-232740 (Patent Document 3) and the like are shown.

従来の攪拌方法では容器の上面を切り取って開口する場合が多く、その容器内に使い残しの塗料があっても、それを保管する方法に苦労していた。保管が大変なのでそのまま廃棄することもあり、材料の無駄遣いだけでなく、地球に対する負荷という観点でも改善が求められる状況であった。塗料を残したい場合には、上面の部分にビニール袋を被せてガムテープで封じるようにするが、手間がかかり、積んで保管することも難しく、また、封じ方が完全でない場合には塗料の溶剤が揮発して硬化して使い物にならないという問題も抱えている。 In the conventional stirring method, the upper surface of the container is often cut and opened, and even if there is paint left over in the container, it has been difficult to store it. Since storage is difficult, it can be discarded as it is, and not only wasted material but also improved from the viewpoint of the burden on the earth. If you want to leave the paint, cover it with a plastic bag and seal it with gummed tape. However, it takes time, it is difficult to store it, and if it is not completely sealed, the solvent of the paint There is also a problem that volatilizes and hardens and cannot be used.

本発明の攪拌装置は、所定長さの軸部材の回転軸の先端部に攪拌翼が取付けられている攪拌装置という特徴に加えて、前記回転軸が回転中には前記攪拌翼が広がっており、前記回転軸が回転を停止している時には前記攪拌翼が軸方向に寄せられた姿勢となっていることを第１の特徴として、
第２に、前記第１の特徴に加えて、重力方向から傾いた姿勢の前記回転軸に取り付けられた複数の攪拌翼が互いに軸対象の姿勢を維持する姿勢制御ストッパーが備えられていることを特徴とする。In addition to the feature of the stirring device in which the stirring blade is attached to the tip of the rotating shaft of the shaft member having a predetermined length, the stirring device of the present invention has the stirring blade spread while the rotating shaft is rotating. The first feature is that when the rotating shaft stops rotating, the agitating blade is in a posture brought close to the axial direction.
Second, in addition to the first feature, a plurality of stirring blades attached to the rotary shaft in a posture inclined from the direction of gravity are provided with a posture control stopper that maintains the posture of the shaft object with respect to each other. Features.

本発明の攪拌装置を使用すると、１６キログラム程度の分量の塗料の一般的な販売容器である角缶の上面を切り開かなくても、角缶容器の約５０ミリメートル直径の注ぎ口から、本発明の攪拌装置を挿入し、挿入後に回転軸を回転させることで効果的に前記角缶容器内部の塗料を均一に攪拌することができる。攪拌作業を完了後、前記攪拌装置は前記注ぎ口から引き戻すことができる。このため、攪拌後の塗料を必要なだけ注ぎ口から取り出した後に、もともと容器に取付けてあった前記角缶の注ぎ口の蓋を閉めることで、残りの塗料を簡単に保管することができる。ある程度時間が経過した後に、再攪拌を行いたい場合でも、前記攪拌装置を挿入、回転、引き抜きの一連の作業を再度行うことで容易に再攪拌を行える。本発明は前記角缶容器内の塗料の攪拌に限らず、容器の口が細くて内部が広がっている容器内部の塗料などの流体を効果的に攪拌することにも効果がある。 When the stirring device of the present invention is used, it is possible to remove from the spout having a diameter of about 50 mm of the square can container without opening the top surface of the square can, which is a general sales container for a coating amount of about 16 kilograms. By inserting the stirring device and rotating the rotary shaft after the insertion, the paint inside the square can container can be effectively stirred uniformly. After completing the stirring operation, the stirring device can be pulled back from the spout. For this reason, after taking out the paint after stirring from the spout as much as necessary, the remaining paint can be easily stored by closing the spout lid of the square can originally attached to the container. Even when re-stirring is desired after a certain amount of time has elapsed, re-stirring can be easily performed by performing a series of operations of inserting, rotating, and pulling out the stirrer again. The present invention is not limited to the stirring of the paint in the square can container, and is effective in effectively stirring the fluid such as the paint in the container whose mouth is narrow and the inside is widened.

本発明の攪拌装置について、図１から図６の６つの図面を用いて説明する。図１は角缶１００中の塗料１０１の中に攪拌装置１を浸して静止している第１の状態を示している。攪拌装置は回転していない状態である。攪拌翼２が回転軸３に取付けられている。この取付けられ方の詳細について説明する。図に描いてある前記回転翼は同じ形状の２枚の翼で構成されている。１枚の翼の形状は左右が互いに反対方向に折り曲げられたシャモジ形の形状に近い形状である。この回転翼は厚み３ｍｍのステンレス板でできている。前記小さな円の中心位置には穴径５ｍｍの貫通穴が設けられている。前記貫通穴を支点としてバランスをとると前記攪拌翼は前記大きな円を鉛直方向に向けた姿勢となっている。一方、前記回転棒は太さが１０ｍｍで長さが１０００ｍｍの円柱形である。この回転棒の先端部分の側面に穴径５ｍｍの貫通穴が空けられている。前記攪拌翼２枚と前記回転棒に設けられた貫通穴を貫くピン５によってこの３つの部品は留められている。前記攪拌翼は回転が自由な状態でピン留めされているので、大きな円部分を下方にした姿勢となる。前記回転軸は前記攪拌翼が取付けられた先端以外の部分が円筒形の固定軸６でカバーされた状態となっている。前記固定軸の他端には電動ドリル７が取り付けられている。このドリルの回転棒には前記回転軸が接続されている。前記固定軸の中間位置には鍔９が配置されている。この鍔は攪拌装置の下方先端部分が前記角缶の底面に接触しないわずか上方に位置するように位置を調整できるように半固定の状態となっている。 The stirring device of the present invention will be described with reference to the six drawings of FIGS. FIG. 1 shows a first state in which the stirrer 1 is immersed in the paint 101 in the square can 100 and is stationary. The stirrer is not rotating. A stirring blade 2 is attached to the rotating shaft 3. The details of the mounting method will be described. The rotor blade illustrated in the figure is composed of two blades having the same shape. The shape of one wing is a shape close to the shape of a camouflage shape in which the left and right sides are bent in opposite directions. This rotor blade is made of a stainless steel plate having a thickness of 3 mm. A through hole having a hole diameter of 5 mm is provided at the center of the small circle. When balanced with the through hole as a fulcrum, the stirring blade is in a posture in which the large circle is directed in the vertical direction. Meanwhile, the rotating rod has a cylindrical shape with a thickness of 10 mm and a length of 1000 mm. A through hole having a hole diameter of 5 mm is formed on the side surface of the tip portion of the rotating rod. These three parts are fastened by two stirring blades and a pin 5 that penetrates a through hole provided in the rotating rod. Since the agitating blade is pinned in a freely rotating state, it has a posture in which a large circular portion is directed downward. The rotating shaft is in a state where a portion other than the tip to which the stirring blade is attached is covered with a cylindrical fixed shaft 6. An electric drill 7 is attached to the other end of the fixed shaft. The rotary shaft is connected to the rotary rod of the drill. A flange 9 is disposed at an intermediate position of the fixed shaft. This bowl is in a semi-fixed state so that the position can be adjusted so that the lower tip of the stirring device is positioned slightly above the bottom of the square can.

図２には図１で示した攪拌装置１を塗料１０１が入った角缶１００の注ぎ口から出し入れする状態を示した。この出し入れする状態を第２の状態と呼ぶ。第２の状態では、攪拌装置は図１で示した第１の状態と同じ姿であり、直径５０ｍｍの注ぎ口の狭い穴を通り抜けられる。 FIG. 2 shows a state in which the stirring device 1 shown in FIG. 1 is put in and out from the spout of the square can 100 containing the paint 101. This state of taking in and out is referred to as a second state. In the second state, the stirrer is the same as in the first state shown in FIG. 1, and can pass through a narrow hole in the spout having a diameter of 50 mm.

図３は図１および図２で示した攪拌装置１を使って角缶１００の中の塗料１０１を攪拌している第３の状態について描いたものである。回転軸３をドリル７によって回転させている。この回転軸の回転によって、攪拌翼２が塗料の流体としての力に押し出されて横方向に広がっている状態である。前記攪拌翼は回転時にきれいに開くように、静止状態における各攪拌翼の外側、回転状態における上部が、回転方向にひねり曲げた状態になっている。その結果、図１の姿勢で回転軸を回転させると塗料の流体としての力によって、攪拌翼の大きな円の部分が軸中心から軸の周囲の方向に広がり、幅広い部分をこの攪拌翼で攪拌できるようになっている。図３に示した第３の状態では前記注ぎ口は通過できない。図３において攪拌装置はその回転軸が重力方向から傾いている。この状態で攪拌翼は前記回転軸を対称軸として回転している。 FIG. 3 illustrates a third state in which the paint 101 in the square can 100 is being stirred using the stirring device 1 shown in FIGS. 1 and 2. The rotating shaft 3 is rotated by a drill 7. By this rotation of the rotating shaft, the stirring blade 2 is pushed out by the force as the fluid of the paint and spreads in the lateral direction. The stirrer blades are twisted in the direction of rotation so that the stirrer blades open cleanly when rotated, the outside of each stirrer blade in a stationary state and the upper portion in the rotated state. As a result, when the rotary shaft is rotated in the posture shown in FIG. 1, the large circular portion of the stirring blade spreads from the shaft center to the periphery of the shaft due to the force as the fluid of the paint, and a wide portion can be stirred by this stirring blade. It is like that. In the third state shown in FIG. 3, the spout cannot pass. In FIG. 3, the rotating shaft of the stirring device is inclined from the direction of gravity. In this state, the stirring blade rotates with the rotation axis as the axis of symmetry.

図４から図６にはそれぞれの状態の本発明の攪拌装置の先端部分を描いた。図４には、攪拌翼２を取り付ける前の状態を描いている。回転軸３の先端にはＵ字金具１０が取り付けられている。このＵ字金具にはピン１１が通されている。攪拌翼２の形状はシャモジ型の形状であり、図に描くように突起が出ている。これをストッパー１２と呼ぶこととする。図５には攪拌翼２が取り付けられた攪拌装置１を塗料１０１の中に浸して静止している第１の状態を描いてある。（２つの攪拌翼はＵ字金具１０のピンを軸としてＸ字型に取り付けられている。図に描くようにストッパー１２がＵ字金具の異なる辺と接している。この状態で角缶開口部１０２を通過することができる。図６は回転軸３を回転した状態（第３の状態）である。攪拌翼２が広がっている様子がわかる。 4 to 6 show the tip of the stirring device of the present invention in each state. FIG. 4 shows a state before the stirring blade 2 is attached. A U-shaped bracket 10 is attached to the tip of the rotating shaft 3. A pin 11 is passed through the U-shaped metal fitting. The shape of the stirring blade 2 is a chamo-ji type shape, and protrusions are projected as shown in the figure. This is called a stopper 12. FIG. 5 illustrates a first state in which the stirring device 1 to which the stirring blade 2 is attached is immersed in the paint 101 and is stationary. (The two stirring blades are attached in an X shape with the pin of the U-shaped bracket 10 as an axis. As shown in the figure, the stopper 12 is in contact with different sides of the U-shaped bracket. 6 shows a state (third state) in which the rotating shaft 3 is rotated, and it can be seen that the stirring blades 2 are spread.
