【発明の詳細な説明】 本発明は、熱可塑性合成樹脂製巻粋の製造方法に関する
ものであり、更に詳しくは、電線、鉄線、糸、モノフィ
ラメント等を巻回するのに好適な熱可塑性合成樹脂製巻
粋の製造法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a thermoplastic synthetic resin winding, and more specifically to a thermoplastic synthetic resin suitable for winding electric wire, iron wire, thread, monofilament, etc. This paper relates to a method of manufacturing seimakisui.

従来、この種巻枠としては、木製、金属製のものが多か
った。Conventionally, this type of winding frame has often been made of wood or metal.

しかし近年原料となる木材資源の不足、製造工程、製作
コストの面で問題があるため、熱可塑性合成樹脂製のも
のが多く用いられるようになった。However, in recent years, there have been problems with the lack of wood resources as raw materials, the manufacturing process, and production costs, so products made of thermoplastic synthetic resin have come to be used more frequently.

熱可塑性合成樹脂を原料として巻枠を製造する場合は、
射出成形法によるが、この方法により巻胴部とフランジ
部とが一体となったものを製造するためには複雑な射出
成形金型が必要となり、コスト高になることはさけられ
なかった。When manufacturing a winding frame using thermoplastic synthetic resin as raw material,
This method is based on injection molding, but in order to manufacture a product in which the winding trunk and flange are integrated by this method, a complicated injection mold is required, which inevitably increases costs.

このため、巻粋の筒状部と、フランジ部とを別別に製造
しておき筒状部の両端部に、外方からフランジ部を接着
して筒状部とフランジ部とを一体にする方法が提案され
ている。For this reason, there is a method in which the cylindrical part and the flange part of the roll are manufactured separately, and then the flange parts are glued from the outside to both ends of the cylindrical part to integrate the cylindrical part and the flange part. is proposed.

しかしながら、この方法で両者を接着する方法では、筒
状体とフランジ部との接着のために有機溶剤を使用する
必要があり、かかる有機溶剤は作業環境を悪化させて労
働衛生上好ましくないばかりでなく、引火し易いという
危険もあり、また、合成樹脂成形品へ悪影響を与えると
いった問題があった。However, in this method of bonding the two, it is necessary to use an organic solvent to bond the cylindrical body and the flange, and such organic solvents worsen the working environment and are not good for occupational health. However, there was a risk that it could easily catch fire, and there were also problems in that it had an adverse effect on synthetic resin molded products.

本発明者等はかかる状況に鑑み、筒状体とフランジ部と
の接着に、超音波溶着法が適用できないか否かを検討し
た。In view of this situation, the present inventors investigated whether an ultrasonic welding method could be applied to bonding the cylindrical body and the flange portion.

従来、熱可塑性合成樹脂同志を溶着する方法としては、
熱溶着、高周波溶着、超音波溶着等の方法が行なわれて
いるが、比較的低融点で剛性の大きい熱可塑性合成樹脂
成形物を溶着するには、溶融しろを取る必要がなく、溶
着後もパリと呼ばれる溶融カスを取除く必要もないこと
から超音波溶着法が好適に用いられている。Conventionally, methods for welding thermoplastic synthetic resins together include:
Methods such as heat welding, high frequency welding, and ultrasonic welding are used, but in order to weld thermoplastic synthetic resin molded products with relatively low melting points and high rigidity, there is no need to remove the melting margin, and even after welding, there is no need to remove the melting margin. The ultrasonic welding method is preferably used because there is no need to remove molten debris called sludge.

しかし、この超音波溶着法は、超音波発振機の電気振動
エネルギーを機械振動エネルギーに変換して、これを集
束させた振動子ホーンを溶着物に押圧することにより、
振動エネルギーを溶着物の溶着しようとする合せ目に集
中させ、局部的な温度上昇を惹起させ合成樹脂を軟化溶
融させて接着させるものであるから、振動方向に対して
直角方向の面の溶着は良好に行なわれるが、振動方向に
対して平行方向の面は良好に溶着し難かった。However, this ultrasonic welding method converts the electrical vibration energy of an ultrasonic oscillator into mechanical vibration energy, and presses a vibrator horn that focuses this energy onto the welded object.
Since vibrational energy is concentrated at the joint of the welding material to cause a local temperature rise and the synthetic resin is softened and melted, welding occurs on surfaces perpendicular to the direction of vibration. Although the welding was carried out well, it was difficult to weld well the surfaces parallel to the vibration direction.

本発明者等は超音波溶着方法のこのような欠点を解消し

発明を完成した。The inventors of the present invention have conducted various studies in order to solve these drawbacks of the ultrasonic welding method and obtain uniform and good welding of the combination of the cylindrical body and the fitting flange using the ultrasonic welding method. The inventors have discovered that the above problem can be solved by creating a special relationship between the structures of the cylindrical body and the flange, and by performing welding under special conditions, and have completed the present invention.

本発明の目的は、熱可塑性合成樹脂製巻枠を、安全に、
工業的に有利に製造する方法を提供することにある。The object of the present invention is to safely and efficiently make a thermoplastic synthetic resin winding frame.
The object is to provide an industrially advantageous manufacturing method.

存する。The gist of this article is that when manufacturing a thermoplastic synthetic resin winding frame using a thermoplastic synthetic resin cylindrical body and fitting flanges that are fitted over both ends of the cylindrical body from the outside, The fitting flange has a slightly smaller outer diameter than the inner diameter of the cylindrical body, and is composed of a plurality of interrupted tongue pieces that can be inserted into the cylindrical body with a slight gap. A protrusion is provided, the protrusion is inserted inside the end of the cylindrical body, the fitting flange is placed over the end of the cylindrical body, and then the central part of the fitting flange is pressed by a vibrator horn to close the fitting flange. The present invention resides in a method for manufacturing a thermoplastic synthetic resin roll, characterized in that the protrusions are brought into close contact with the inner surface of the cylindrical body, and the cylindrical body and the protrusions of the fitting flange are welded using ultrasonic waves.

行方向の面Ｂは全く溶着が行われないことになる。Even when the cylindrical body 1 and the fitting flange 2 are combined as shown in FIG. 1, the center part of the fitting flange 2 is not pressed as shown in FIG. If the surface in contact with the transducer horn 8 is smooth and the diameter of the transducer horn 8 is the same as or larger than the diameter of the cylindrical body 1, even if the transducer horn is pressed and ultrasonic waves are applied while it is in the pressed state, the tube will not move. The shaped body 1 and the fitting flange 2 should be welded only on the welding surface in the direction A in FIG. become.

振動子ホーン８の嵌合フランジ２に当接する面が突出す

定することが望ましい。The pressing force applied to the fitting flange 2 by the vibrator horn 8 is determined by the ratio of the inner diameter of the cylindrical body 1 and the diameter of the vibrator horn 8, and the ratio of the inner diameter of the cylindrical body 1 to the projection 3 provided on the fitting flange 2. It is desirable to determine it appropriately because it varies depending on the size of the gap formed between the outer diameter and the type of resin used to manufacture the cylindrical body and the fitting flange.

本発明方法においては、上記のように振動子ホーン８に
よって嵌合フランジ２の中央部分を押圧し、押圧状態を
継続したまま振動子ホーン８に超音波を印加する。In the method of the present invention, as described above, the central portion of the fitting flange 2 is pressed by the vibrator horn 8, and ultrasonic waves are applied to the vibrator horn 8 while the pressed state is continued.
