着材へ塗布する方法に関するものであり、特に１８を金
属缶等の容器の接着による製造においで有効な粉末状接
着剤の塗布方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for efficiently applying powdered adhesive to an adherend without contaminating areas other than the adhesive-applied area of the adherend by scattering adhesive particles. In particular, No. 18 relates to a powder adhesive application method that is effective in manufacturing containers such as metal cans by adhesion.
従来、粉末状接着剤は、フィルム状接着剤に比べ、任意
の形状に、容易に塗布できるため、塗布作業に有利な接
着剤として、洋服の芯地の接着等に多く利用されている
。Conventionally, powdered adhesives can be applied to arbitrary shapes more easily than film-like adhesives, so they have been widely used for bonding interlinings of clothes, etc., as adhesives that are advantageous in application work.
しかしながら、芯地等の平面に均等にバラ散布するよう
な場合には、スクリーンを通して粉体粒子を落下させる
事により、容易に接着剤を被着体へ塗布することができ
るが、部分的に特定の形状に粉体粒子を塗布したい場合
、例えば１８Ｌ金属缶の接−による製造において、缶胴
板の端縁部のみに接着剤を塗布したいという様な場合に
は以下のような問題を有していた。However, when dispersing the adhesive evenly on a flat surface such as interlining, it is possible to easily apply the adhesive to the adherend by dropping the powder particles through a screen, but it is difficult to When it is desired to apply powder particles in the shape of a metal can, for example, in the production of 18L metal cans by bonding, when it is desired to apply adhesive only to the edge of the can body plate, the following problems arise. was.
■接着剤粒子が、意図した場所以外（非塗布部分）へ塗
布時に付着する事。■Adhesive particles may adhere to areas other than the intended areas (non-applied areas) during application.
被着体の非塗布部分への付着を防止するのにマ 。Useful to prevent adhesion to non-coated parts of the adherend.
スキング材を用いる事は広く行なわれている手段である
が、被着体ごとにマスキング材を取り付け、取り外しを
行わねばならず、接着剤塗布の連続化、高速化を阻害す
るうえに、工業的に省エネルギー上マスキング材を繰返
し使用することが多いが、マスキング材に付着した接着
剤の除去は、以下に述べる■の問題点とも関連しており
■の問題点を解決しようとすればする程、困難になる。Using a masking material is a widely used method, but the masking material must be attached and removed for each adherend, which not only hinders continuous and high-speed adhesive application, but also makes it difficult to apply industrially. Masking materials are often used repeatedly to save energy, but the removal of adhesive adhered to the masking materials is also related to the problem (■) described below, and the more we try to solve the problem (■), the more It becomes difficult.
完全に接着剤を取り除いたマスキング材を使用しなけ゛
れば、マスキング材を用いることにより被着体をむしろ
汚染してしまう結果になり、マスキング材を用いる意味
が失なわれる結果になる。If a masking material from which the adhesive has been completely removed is not used, the use of the masking material will end up contaminating the adherend, and the purpose of using the masking material will be lost.
（巧塗布後の被着体を、加熱融着等の次の工程への移送
中に、移送により発生する気流・振動等により、塗布形
状の崩れ、接着剤粒子の飛散が発生し、汚染や接着不良
の原因となる事。(When the adherend is transferred to the next process such as heat-sealing after being coated, the air currents and vibrations generated by the transfer may cause the coated shape to collapse and the adhesive particles to scatter, resulting in contamination and This may cause poor adhesion.

程（接着及びその他の工程）を１秒以下にしなければな
らず、高速で接着剤を塗布しなければならないが、上記
■及び■の問題がからんで高速塗布が困難である事。■In order to increase productivity, there has recently been a demand for faster speeds, especially in all processes. For example, in the production of first metal cans, it is required to produce more than 60 cans per minute, which is 1 second per second. Processing of more than one can, that is, the process per can (adhesion and other processes) must be less than 1 second, and the adhesive must be applied at high speed, but the problems of Difficult to apply.
以上の様な問題により、粉末状接着剤を用いる事が、塗
布方法等にメリットが多くありながら、困難な場合が多

。In the figure, 1 is the ground 3 on which the adherend is placed. Shows a conductive belt with a conductive belt. It is sent from the previous process and is coated with adhesive powder 5. At this time, parts of the adherend 2 other than those to which the adhesive is applied are covered with a conductive belt-shaped masking material 6 having a ground (not shown) to prevent adhesive powder from adhering. If the coating capacity of the electrostatic coating device 4 is insufficient, a plurality of electrostatic coating devices 4' may be installed in parallel depending on the required coating amount. The adherend 2' coated with adhesive is
The belt 1 sends it to the next process such as a heat fusion process. The belt and masking material are brushed by rotating brushes 7 and 8, respectively, to remove adhering adhesive powder. The fallen adhesive powder is collected in hopper 9,
It will be collected on 10th. The recovered powder can be reused. In addition, the adhesive can be applied while the belt truck is continuously moving to convey the adherend, or the belt truck can be moved intermittently and the electrostatic coating device can be moved and applied to the adherend when it is stopped. , or a combination thereof.
本発明の効果を発現するためには、被着体２はベルト及

のわずかな空隙ヲ鰻ければよい。As an insulation method, if the adherend is a coated metal plate used in manufacturing metal cans, etc., the coating material can often be used as an insulating material, so it can be used as is without considering any particular insulation measures. In the case of an adherend whose surface is not electrically insulated, a thin insulating sheet large enough to be completely covered by the adherend should be pasted on the belt surface between the belt and the adherend. Just attach it. Further, for insulation from the masking material, it is sufficient to similarly affix an insulating sheet to the adherend side of the masking material, or to create a small gap that does not distort the applied shape.

とができるものである。In addition, any conductive material can be used for the belt and masking material, but considering strength and long-term use, it is preferable to use steel belts such as stainless steel, which has strong strength and high corrosion resistance. Commonly used powder adhesives can be used in the invention method, but from the viewpoint of chargeability, nylon adhesives, polyester adhesives, and copolymers of these can be used as the main ingredients. It is preferable to do so. In addition, the particle size of these powder adhesives is preferably 60 to 250 μm from the viewpoint of preventing secondary agglomeration. The method of the present invention uses an electrostatic coating device as a means for applying the powder adhesive. It has one characteristic in particular. Static coating is a method in which adhesive particles are charged and then sprayed onto the adherend (1) to uniformly coat the adhesive particles.In the present invention, an insulated adherend is used. In addition, after the adhesive particles are applied, the applied adhesive particles may be removed from the adherend due to vibrations or air currents that occur during transport of the adherend to the next process such as heat fusion. This can prevent the paint from falling off and the shape of the coating from collapsing.

有効である。When applying adhesive particles to an adherend using an electrostatic coating device, adhesive particles inevitably adhere to the masking material and the belt, contaminating them; however, the masking material and belt are electrically conductive. And because it is grounded,
The electric charge held by the adhesive particles disappears quickly and can be easily removed by brushing or the like, allowing continuous use of the masking material and belt, as well as use in high-speed application. Note that it is even more effective to use a vacuum hopper or the like, and it is also effective for reusing adhesive particles.
