本発明は、パイプ、チューブなどのいわゆる管材の内壁
に粘着物質を塗布する粘着物質塗布方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of applying an adhesive substance to the inner wall of a so-called pipe material such as a pipe or a tube.
従来、パイプ、チューブなどの管内壁に粘着物質を塗布
する手段として、たとえば傾斜させた管材を回転させ、
その上方から粘着物質を流し込む方法がとられている。Conventionally, as a means of applying an adhesive substance to the inner wall of pipes, tubes, etc., for example, by rotating a tilted pipe material,
A method is used in which adhesive material is poured from above.
この方法は、粘着物質が比較的低粘度の場合は問題ない
が、粘着物質が高粘度の場合や、粘着物質を厚く塗布し
たいような場合には、管内全域を均一に塗布し得ない難
点がある。This method has no problems if the adhesive substance has a relatively low viscosity, but if the adhesive substance has a high viscosity or if you want to apply it thickly, it has the disadvantage that it cannot be applied uniformly to the entire area inside the pipe. be.
筐た、従来他の手段として、管内にスプレーガンを挿入
し、これによって管内壁に粘着物質を塗布する方法もと
られているが、この方法も前者と同様、粘着物質が低粘
度の場合か、薄い塗布層の場合に限られる。Another conventional method has been to insert a spray gun into the pipe and use it to apply a sticky substance to the inner wall of the pipe, but like the former method, this method also works if the sticky substance has a low viscosity. , limited to thin coated layers.
本発明の目的は、上記従来の問題点を解消し、高粘度の
粘着物質であっても、管内壁に所望厚さの粘着物質を均
一に塗布することのできるこの種方法を提供しようとす
るものである。An object of the present invention is to solve the above-mentioned conventional problems and provide a method of this type that can uniformly apply a desired thickness of adhesive substance to the inner wall of a pipe, even if the adhesive substance is highly viscous. It is something.

方向への不安定な動きを規制されている。Reference numeral 2b indicates a pipe inner wall contact guide provided protrudingly extending in the tube axis direction on the adhesive material rubbing surface 2a, and the adhesive material sliding member 2 contacts the pipe via the guides 2b provided in plurality in the circumferential direction The tube 1 is in contact with the inner wall of the tube 1, and unstable movement in a direction intersecting the axial direction of the tube 1 is restricted.
３は粘着物質摺擦部材２を矢印Ｘ方向に移動させるため
、この部材２の先端に取付けた牽引ワイヤで、ワイヤ３
の他端側は、図示しない巻取りドラムに巻取られるよう
になっている。3 is a pulling wire attached to the tip of the adhesive material rubbing member 2 in the direction of arrow X;
The other end side is adapted to be wound up on a winding drum (not shown).
４は管１内において、粘着物質摺擦部材２の進行方向前
方に充てんした粘着物質を示す。Reference numeral 4 indicates an adhesive substance filled in the tube 1 in front of the adhesive substance rubbing member 2 in the traveling direction.
そして、上記にわいて管１の内壁に粘着物質４を均一に
塗布するには、管１内に挿入した粘着物質摺擦部材２を
牽引ワイヤ３を介して矢印Ｘ方向に移動させればよい。In order to uniformly apply the adhesive substance 4 to the inner wall of the tube 1 in the above manner, the adhesive substance rubbing member 2 inserted into the tube 1 may be moved in the direction of the arrow X via the pulling wire 3. .
すなわち、粘着物質摺擦部材２には、管１の内壁との間

おり、また、上記摺擦面２ａには、管内壁接触ガイド２
ｂが突設されているから、このガイド２ｂを案内とする
部材２の移動はスムーズであり、管１内において不安定
彦揺動が生ずることはない。That is, the adhesive material rubbing member 2 has an adhesive material rubbing surface 2a formed thereon with an appropriate distance between it and the inner wall of the tube 1, and the sliding surface 2a has a surface that is in contact with the inner wall of the tube. Guide 2
Since the guide 2b is provided in a protruding manner, the movement of the member 2 using the guide 2b as a guide is smooth, and unstable swinging does not occur within the tube 1.
しかして、上記粘着物質摺擦部材２の移動に際し、管１
内に充てんされている粘着物質４は、この部材２の摺擦
面２ａ部分によって管内壁に摺擦展着されるから管内全
域には、均一厚さの粘着物質塗布層４０が形成される。Therefore, when the adhesive substance rubbing member 2 is moved, the pipe 1
The adhesive substance 4 filled inside the tube is rubbed and spread on the inner wall of the tube by the sliding surface 2a of this member 2, so that an adhesive substance coating layer 40 having a uniform thickness is formed over the entire inside of the tube.
本発明の実験例を下記する。Experimental examples of the present invention will be described below.
管１として、外径１２０ｔｒｒｒｎ、内径１００ｒｒｒ
ｍのクロロプレンゴムを用いた。As pipe 1, outer diameter 120trrrn, inner diameter 100rrr
m chloroprene rubber was used.
捷た、粘着物質４としては、粘度が５００００ｃＰ（セ
ンチポイズ）のエチレンコポリマを主体とする高粘度材
