Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は粘性液体の塗布方法に関する。Description: TECHNICAL FIELD The present invention relates to a method for applying a viscous liquid.
（従来の技術） 従来、この種の塗布方法としては、第４図に示す特開
昭49−21278号のように、接着剤の如き粘性液体の糸引
きに対し、横方向から熱風をあて、粘度を下げて切断す
る方法が良く利用されている。(Prior art) Conventionally, as this kind of coating method, as shown in Japanese Patent Application Laid-Open No. 49-21278 shown in FIG. 4, hot air is applied to stringing of a viscous liquid such as an adhesive from the lateral direction. A method of cutting with lower viscosity is often used.
また、連続塗布をする場合、第５図（ａ）（ｂ）に示
すように、ノズル１′を移動させつつ被塗布材４′に塗
布しているが、この場合、ノズル１′と被塗布材４′と
の間に若干の空間がある。In the case of performing continuous coating, as shown in FIGS. 5 (a) and 5 (b), the nozzle 1 'is moved and the coating is performed on the coating material 4'. There is some space between the material 4 '.
さらに、第６図（ａ）（ｂ）に示すように、ノズル
１′を被塗布材４′に近づけて塗布する方法がある。Further, as shown in FIGS. 6 (a) and 6 (b), there is a method in which the nozzle 1 'is applied close to the material 4' to be applied.
（発明が解決しようとする課題） しかしながら、前者の方法では、加熱装置が必要にな
るし、装置が大がかりになり、かつノズルの先端を小さ
くすることが難しい。(Problems to be Solved by the Invention) However, in the former method, a heating device is required, the device becomes large, and it is difficult to reduce the tip of the nozzle.
また、このようにして熱を加えて粘度低下させる方法
では、糸引き部だけではなく、ノズルおよびそれ以外の
場所も熱が加わる可能性があり、例えば熱硬化性の液体
などは、液体が時間とともにゲル化してしまう、等の問
題点があった。In addition, in the method of reducing the viscosity by applying heat in this manner, not only the stringing portion but also the nozzle and other places may be heated. However, there are problems such as gelation.
一方、後者の第６図の方法では、ノズル１′を被塗布
材４′になるべく近づけるため、第６図（ｂ）に示すよ

ーナ部などでは、第５図（ｂ）において破線の丸で囲ん
だ部分に示すように、塗布の遅れがあるあめ、アールが
ついてしまったりする、といった課題があった。On the other hand, in the latter method of FIG. 6, since the nozzle 1 'is brought as close as possible to the material 4' to be coated, the coating state is stabilized as shown in FIG. 6 (b), but the lower part of FIG. As shown in the figure, build-up occurs in which the viscous liquid adheres to the tip of the nozzle 1 '. However, as shown in FIG.
The farther the nozzle 1 'is released, the more delay occurs when the viscous liquid reaches the material 4' to be applied, and the applied state is not stable. In addition, in the corner portion or the like, a circle indicated by a broken line in FIG. As shown in the dashed part, there were problems such as candy with a delay in application and roundness.
この発明は上記のような問題点を解消するためになさ
れたもので、その目的とするところは、ノズル先端を小
さくでき、熱等の不安定要素を取り除き常温で塗布でき
るとともに、糸引きを小さくし、かつ連続塗布において
は安定した塗布状態が得られる粘性液体の塗布方法を提
供することにある。The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to make the tip of the nozzle small, remove unstable elements such as heat, and apply at normal temperature, and reduce stringing. Another object of the present invention is to provide a method for applying a viscous liquid which can obtain a stable application state in continuous application.
（課題を解決するための手段） 本発明では下記構成にて上記目的を達成している。(Means for Solving the Problems) In the present invention, the above object is achieved by the following constitution.
第１の手段として、ノズルに出し入れ自在なニードル
を設け、粘性液体を定量塗布した後、ノズルのみ所定の
位置に上昇させ、その後ニードルを上昇させることによ
り、糸引き部の粘性液体をニードルにつられて上昇さ
せ、糸引きを小さくすることを特徴としている。As a first means, a needle which can be taken in and out of the nozzle is provided, and after the viscous liquid is applied in a fixed amount, only the nozzle is raised to a predetermined position, and then the needle is raised, so that the viscous liquid in the threading portion is attached to the needle. It is characterized by lowering the stringing.
第２の手段として、ノズルに出し入れ自在なニードル
を設け、粘性液体を定量塗布した後、ノズルのみ所定の
位置に上昇させ、その後ニードルを、軸中心に回転させ
ながら上昇させることにより、糸引き部の粘性液体をニ
ードルにつられて上昇させ、糸引きを小さくすることに
特徴を有している。A second means is to provide a needle which can be taken in and out of the nozzle, apply a constant amount of the viscous liquid, raise only the nozzle to a predetermined position, and then raise the needle while rotating it around the axis, thereby obtaining a threading unit. It is characterized in that the viscous liquid is raised by the needle to reduce stringing.
第３の手段として、ノズルに出し入れ自在なニードル
を設け、粘性液体を連続塗布する時、突出させたニード
ルを塗布面に近づけ、かつニードルに沿わせて粘性液体
を連続塗布させることを特徴としている。A third means is to provide a needle which can be taken in and out of the nozzle, and to continuously apply the viscous liquid when the viscous liquid is continuously applied, the protruding needle is brought close to the application surface and the viscous liquid is continuously applied along the needle. .
（作用） 本発明では上記第１の手段のようにし、ニードルはノ
ズルに比べ、かなり細いため、細いニードルに付着する
粘性液体の量は僅かである。したがって、先ずノズル上
昇後、ニードルを上昇させ、糸引きを小さくしている。(Operation) In the present invention, as in the above-described first means, the amount of the viscous liquid adhering to the fine needle is small because the needle is considerably thinner than the nozzle. Therefore, first, after raising the nozzle, the needle is raised to reduce stringing.
また、第２の手段のようにし、ニードル上昇時に回転
させ、糸引きをネジ切るようにして糸引きを小さくして
いる。Further, as in the second means, the needle is rotated when the needle is raised, and the threading is threaded to reduce the threading.
さらに、連続塗布に際しては、ニードルを被塗布材の
塗布面に近づけて粘性液体を塗布するが、ニードルはノ
ズルに比べ細いため、その分ビルドアップ発生が少なく
なり、また、塗布面に近づけて塗布するため、粘性液体
塗布の遅れがなく、塗布が安定し、かつコーナー部にお
いても、ほぼ鋭角でもって粘性液体を塗布できるように
している。Furthermore, during continuous application, the viscous liquid is applied by moving the needle closer to the application surface of the material to be applied, but since the needle is thinner than the nozzle, build-up is reduced by that much, and the application is performed closer to the application surface. Therefore, there is no delay in the application of the viscous liquid, the application is stable, and the viscous liquid can be applied at an almost acute angle even at the corner.

A small-diameter needle whose tip is freely inserted into and taken out of the tip of the nozzle 1 is a viscous liquid such as an adhesive, and 4 is a material to be coated.

（ｄ）図に示すように、糸引きを速く切断することがで
きる。In this embodiment, first, the nozzle 1 is lowered to a predetermined position as shown in FIG. 1A, a predetermined amount of the viscous liquid is applied, and then the needle 1 is moved as shown in FIG. 2 is kept as it is, and only the nozzle 1 is raised. When the ascent is completed, the needle 2 is raised as shown in FIG. In this case, since the threading portion rises along the needle 2,
(D) As shown in the figure, the stringing can be cut quickly.

切断し得るようにしたことに特徴を有している。Embodiment 2 FIG. 2 shows a second embodiment of the present invention. In this embodiment, the needle 2 is raised from the state shown in FIG.
In the process of being housed in the nozzle 1, the needle 2 is raised while rotating in an appropriate direction, thereby further reducing the stringing and enabling quick cutting.
なお、ニードル２の回転は、例えばモータの出力軸と
歯車を介しニードル２と連結するなどの適宜の回転機構
によって達せられる。The rotation of the needle 2 can be achieved by an appropriate rotation mechanism such as coupling to the needle 2 via an output shaft of a motor and a gear.

な動作をしてやることにより、糸引きも小さくできる。That is, in the case of continuous application, the needle 2 must be brought close to the material to be applied as shown in FIG. 6 (a). However, as in this embodiment, the needle 2 is protruded and the adhesive 3 is applied along the needle. By applying the coating, a stable coating state can be obtained, and since the needle 2 is considerably thinner than the nozzle 1, build-up in which the liquid adheres to the tip of the nozzle is also eliminated. It should be noted that, at the final point, stringing can be reduced by performing the operations shown in FIGS. 1 (c) and 1 (d).
