本発明は回転摩擦接着法によ′る中空浮子の製造方法に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing hollow floats by rotary friction adhesive method.
中空浮子は、漁網用の浮子として使用されるものであり
、プラスチック製の中空体の中央にロープ挿通用の透孔
を有するものである。このような中空浮子は、先ず２つ

製造されている。接着方法としては、溶剤接着、熱板溶
融接着、回転摩擦接着など種々の方法が知られているが
、作梨効率の良い点、溶剤、接着剤などの副資材を必要
としない点などで回転摩擦接着法が優れている。A hollow float is used as a float for fishing nets, and has a through hole in the center of a hollow body made of plastic for passing a rope through. Such hollow floats are manufactured by first molding the two halves separately and then gluing the halves together. Various bonding methods are known, such as solvent bonding, hot plate melt bonding, and rotary friction bonding, but rotary bonding has the advantage of being more efficient and not requiring secondary materials such as solvents and adhesives. Friction adhesion method is superior.

十分に出す条件で接着し、ロープの挿通孔となる透孔柱
部の接合強度を犠牲にしているのが現状であった。In order to create a complete hollow float using the rotary friction adhesive method, as shown in FIG.
first and second bowl-shaped bodies 10.12'i having 12a;
, by rotating friction adhesive method υ, edge part 1 of bowl-shaped body 10.12
The end faces of the through-hole columns 10a and 12a are bonded together and integrated. However, the edge portion 10
Since the diameters of b and 12b and the end face of the through-hole column are different, the circumferential speeds are also different. Therefore, even if two bowl-shaped bodies 10.12'i are friction bonded under constant pressure and constant friction time, it is difficult to obtain uniform adhesive strength between the edge portion and the through-hole column portion. In other words, the edge strength is 1! l:'a: If the pressure is raised sufficiently, the adhesion of the through-hole column will be weak.On the other hand, if the through-hole column is bonded with sufficient strength, the outer periphery will become weak. Currently, bonding is performed under conditions that provide sufficient bonding strength at the edge portions that form the outer periphery, while sacrificing the bonding strength at the through-hole column portions that serve as the rope insertion holes.
本発明はこのような従来技術の問題点全解決するために
なされたものであシ、回転摩擦接着法によｐ１樹脂材料
のもっている強度を十分に引きだして接着し、強度に優
れた中空浮子を得る方法を提供することを目的とする。The present invention has been made in order to solve all of the problems of the prior art, and it is possible to create a hollow float with excellent strength by fully drawing out the strength of the P1 resin material and adhering it using a rotational friction adhesive method. The purpose is to provide a method to obtain.
すなわち、本発明の中空浮子の製造方法は、中央に透孔

接着し、ついで、この透孔柱に円筒体が嵌装された第１
の椀状体と、中央に透孔柱を有する第２の椀状体とを、
互いの椀状体端縁部全台わせるようにして回転摩擦接着
することを特徴とする。That is, in the method for manufacturing a hollow float of the present invention, a cylindrical body is fitted and bonded to a through-hole column of a first bowl-shaped body having a through-hole column at the center, and then the cylindrical body is attached to this through-hole column. The first
a bowl-shaped body, and a second bowl-shaped body having a through-hole column in the center,
It is characterized in that the end edges of each bowl-shaped body are all rotated and friction-adhered so that they are aligned.
以下、添付図面に沿って本発明をさらに詳細に説明する
。Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
先ず第２−Ａ図、第２−Ｂ図に示すように、中央に透孔
柱１０ａを有する第１の椀状体１０の透孔柱１０ｍの外
周側に円筒体１４ｔその一部を残して嵌入し、接着する
。この接着は接着剤による接着など適宜の方法が採れる
が、次工程とともに回転摩擦接着（溶接）によるのが至
便である。第１の椀状体１０の透孔柱１０ａの外周面と
円筒体１２の内周面とが溶接され、両者は一体化する。First, as shown in Figures 2-A and 2-B, a portion of the cylindrical body 14t is left on the outer circumferential side of the through-hole column 10m of the first bowl-shaped body 10 having the through-hole column 10a in the center. Insert and glue. This bonding can be done by any suitable method such as bonding with an adhesive, but it is most convenient to use rotational friction bonding (welding) together with the next step. The outer circumferential surface of the perforated column 10a of the first bowl-shaped body 10 and the inner circumferential surface of the cylindrical body 12 are welded, and the two are integrated.
次いで、この円筒体１４が嵌装嘔れた第１の椀状体ｌＯ
と、第２の椀状体１２（半割体）とを、それぞれの椀状
体の端縁部１０ｂと１２ｂが、透孔柱１０ａと１２ａの
端面が合うようにして、椀状体を回転して摩擦接Ｎ（溶
接）する。端縁部同志が溶接されて外周面を形成し、透
孔柱は端面同志が溶接される他、その外周面が円筒体の
内周面と溶接されて、ロープ挿通孔１６が形成される。Next, the cylindrical body 14 is inserted into the first bowl-shaped body lO.
and the second bowl-shaped body 12 (half-split body), and rotate the bowl-shaped body so that the end edges 10b and 12b of each bowl-shaped body are aligned with the end faces of the through-hole columns 10a and 12a. and friction weld N (welding). The end edges of the through-hole column are welded together to form an outer circumferential surface, and the end surfaces of the through-hole column are welded together, and the outer circumferential surface is welded to the inner circumferential surface of the cylindrical body to form a rope insertion hole 16.
また、この２つの椀状体（半割体）の回転摩擦接着に際
し、円筒体１４は第２の椀状体１２の透孔柱１２ａのガ
イドとして働くため、透孔柱が多少偏心していても接着
が可能である。Furthermore, when the two bowl-shaped bodies (half bodies) are bonded by rotational friction, the cylindrical body 14 acts as a guide for the through-hole column 12a of the second bowl-shaped body 12, so even if the through-hole column is slightly eccentric, Adhesion is possible.
なお、以上の例において円筒体を透孔柱の外周面に接着
する場合について説明したが、小径の円筒体音用い、こ
れ全透孔に内挿するようにして透孔柱の内周面に接着す
ることも可能である。また、本発明によれば、透孔柱は
円筒体全弁して接着されるので、必ずしも透孔柱の端面
同志が接着される必要がない。In the above example, we have explained the case where a cylindrical body is glued to the outer circumferential surface of a through-hole column, but by using a small-diameter cylindrical body and inserting it into all the through-holes, it can be attached to the inner circumferential surface of a through-hole column. It is also possible to glue. Further, according to the present invention, since the through-hole column is bonded to the entire cylindrical body, it is not necessarily necessary to bond the end surfaces of the through-hole column together.
以上説明したように本発明によれば、円筒体を用いるこ
とにより、透孔柱部が広い面積で接着されてその強度？
大きくすることができ、回転摩擦法により簡便に優れた
強度の中空浮子を製造することが可能となり、中空浮子
のロープ挿通孔部よりの剥離、浸水が大幅に改善された
。As explained above, according to the present invention, by using a cylindrical body, the through-hole column part is bonded over a wide area, and its strength increases.
It has become possible to easily manufacture a hollow float with excellent strength using the rotary friction method, and the peeling of the hollow float from the rope insertion hole and water intrusion have been greatly improved.
また、射出成形により得られる椀状体の透孔柱が多少偏
心しても、透孔柱部の接着面積が増大することから強度
的な問題がない。さらに従来は、透孔柱部の長さがその
接着強度に影曽することから、厳密にその長さ全規定し
ていたが、本発明によればその必要もない。このように
本発明によれは部品の許容度が大幅に増すとともに作業
性が良好となり、生産性が向上する。Further, even if the through-hole pillars of the bowl-shaped body obtained by injection molding are slightly eccentric, there is no problem in terms of strength because the bonding area of the through-hole pillars increases. Furthermore, in the past, since the length of the through-hole column affected its adhesive strength, the entire length was strictly regulated, but according to the present invention, this is not necessary. As described above, according to the present invention, the tolerance of parts is greatly increased, workability is improved, and productivity is improved.
また、浮子の外周部およびロープ挿通孔部ともに接着強
度を向上することができるので、従来は接着性が十分で
ないため使用不能とされていた樹脂も用いることができ
、材料選択の自由度が大きくなった。In addition, the adhesive strength of both the outer periphery of the float and the rope insertion hole can be improved, allowing the use of resins that were conventionally considered unusable due to insufficient adhesive properties, giving greater freedom in material selection. became.
