Description

本発明は、管体を筒状フィルムに挿入する挿入方法および挿入装置に関する。   The present invention relates to an insertion method and an insertion device for inserting a tubular body into a tubular film.

電子写真方式を採用した画像形成装置、いわゆる電子写真装置には、トナー像を電子写真感光体から中間転写体へ一次転写し、その後に中間転写体から転写材（紙やＯＨＰシートなど）へ二次転写する方式（中間転写方式）がある。中間転写体としては、無端状のベルトで形成された筒状フィルムが広く用いられている。
中間転写方式において、一次転写時および二次転写時に画質を悪化させないためには、トナーの飛び散りを小さくすることが重要であり、そのための重要なパラメータとして筒状フィルムの体積抵抗、表面抵抗が挙げられる。体積抵抗は筒状フィルムの材料に適量の導電材を添加することによって、表面抵抗は筒状フィルムの表面に塗布する材料に適量の導電材を添加することによって、所望の機能を付与する方法が知られている。 In an image forming apparatus adopting an electrophotographic system, so-called electrophotographic apparatus, a toner image is primarily transferred from an electrophotographic photosensitive member to an intermediate transfer member, and then transferred from the intermediate transfer member to a transfer material (paper, OHP sheet, etc.). There is a next transfer method (intermediate transfer method). As the intermediate transfer member, a cylindrical film formed of an endless belt is widely used.
In the intermediate transfer method, it is important to reduce toner scattering in order to prevent deterioration in image quality during primary transfer and secondary transfer, and volume resistance and surface resistance of the tubular film are important parameters for that purpose. It is done. Volume resistance is a method of imparting a desired function by adding an appropriate amount of conductive material to the material of the cylindrical film, and surface resistance is adding a suitable amount of conductive material to the material applied to the surface of the cylindrical film. Are known.

また、二次転写時にトナーの残留（以下「転写残トナー」とも記載する）が生じることがあり、この転写残トナーを除去するために、一般的な方法としてブレードによるブレードクリーニング方法が用いられている。このとき、筒状フィルムの表面とブレードとの間の摩擦が高いとブレードの先端が摩耗してしまい、転写残トナーがすり抜けてクリーニング不良となってしまう。そこで、ブレードの先端の摩耗を抑制するために筒状フィルムの表面をラッピングフィルム等で研磨してクリーニングブレードに直行する微細な形状の溝を付与する方法が知られている。このような方法によって、筒状フィルムの表面とブレードとの接触面積を少なくすることにより摩擦を下げることができる。   Further, toner may remain during secondary transfer (hereinafter also referred to as “transfer residual toner”), and a blade cleaning method using a blade is generally used to remove the transfer residual toner. Yes. At this time, if the friction between the surface of the tubular film and the blade is high, the tip of the blade is worn, and the transfer residual toner slips through, resulting in poor cleaning. Therefore, a method is known in which the surface of the cylindrical film is polished with a wrapping film or the like in order to suppress wear at the tip of the blade, thereby providing a finely shaped groove that goes straight to the cleaning blade. By such a method, friction can be reduced by reducing the contact area between the surface of the tubular film and the blade.

このような筒状フィルムの表面に塗料を塗布する工程や表面を研磨する工程を実現するためには、柔軟性のある筒状フィルムの状態では加工が困難なため、筒状フィルムを内面からバックアップして形状を固定する必要がある。一般的な方法として管体を筒状フィルムの内側に実装する方法がある。このとき、管体の外径が筒状フィルムの内径より小さくて、管体の内周面と筒状フィルムの外周面との間に隙間があると筒状フィルムをしっかりバックアップすることができない。そこで、筒状フィルムの周長にバラツキがあることを考慮して、管体の外径は筒状フィルムの最大内径より大きくすることにより筒状フィルムの周長にバラツキがあっても、筒状フィルムを内面から確実にバックアップする方法がとられている。   In order to realize the process of applying paint to the surface of such a cylindrical film and the process of polishing the surface, it is difficult to process in the state of a flexible cylindrical film, so the cylindrical film is backed up from the inner surface. It is necessary to fix the shape. As a general method, there is a method of mounting a tubular body inside a tubular film. At this time, if the outer diameter of the tubular body is smaller than the inner diameter of the tubular film and there is a gap between the inner peripheral surface of the tubular body and the outer peripheral surface of the tubular film, the tubular film cannot be firmly backed up. Therefore, in consideration of the variation in the circumferential length of the tubular film, the outer diameter of the tubular body is made larger than the maximum inner diameter of the tubular film, so that the tubular film can be obtained even if the circumferential length of the tubular film varies. A method of reliably backing up the film from the inner surface is taken.

筒状フィルムの管体への固定方法の一例としては、
テーパ状の呼込み部を具備した管体を垂直に立てた状態にしておき、かつ
円筒形状とした筒状フィルムを、筒状フィルムの中心軸と管体の中心軸とが同軸となる状態にして、管体の上部に配置し、
管体と筒状フィルムとがともに上記の状態から筒状フィルムの下端部の円周方向の数か所を把持して外周方向に拡径した状態において、その拡径されている筒状フィルムを下降させていき、テーパ状の呼込み部を具備した管体に装着する方法が知られている。（特許文献１参照） As an example of the method of fixing the tubular film to the tube,
Keep the tubular body with the taper-shaped drawing portion upright, and make the cylindrical film into the state where the central axis of the tubular film and the central axis of the tubular body are coaxial. Placed at the top of the tube,
In the state where both the tubular body and the tubular film are gripped from the above-mentioned state at several positions in the circumferential direction of the lower end portion of the tubular film and expanded in the outer circumferential direction, the expanded tubular film There is known a method of lowering and attaching to a tube body having a tapered drawing-in part. (See Patent Document 1)

筒状フィルムは薄膜のため取扱いが難しく、筒状フィルムを、筒状フィルムより径の大きい管体に装着する場合、些細な歪み等によって簡単に折れキズ等が発生して不良になってしまう。そのために挿入機構が精密および複雑になり挿入時間も多くかかってしまう。
たとえば、特許文献１で示しているように、筒状フィルムを掛止爪と称しているもので拡径させながら管体に装着する引込機構を用いた方法がある。しかし、掛止爪を外周方向に拡径させる機構が周方向に複数必要であり、またその機構全体を管体の軸方向に移動させる機構が必要であり、さらにはその機構が管体と接触しないようにする必要がある。また筒状フィルムの弾性変形領域を超えないように管体と筒状フィルムとの間に挿入する掛止爪の厚さや機構を設計する必要がある。

また、本発明の他の態様は、筒状フィルムを、当該筒状フィルムより径の大きい管体に、より容易に装着し得る、管体を筒状フィルムに挿入する装置の提供に向けたものである。 The tubular film is difficult to handle because it is a thin film, and when the tubular film is attached to a tubular body having a diameter larger than that of the tubular film, it is easily broken due to a slight distortion or the like and becomes defective. For this reason, the insertion mechanism becomes precise and complicated, and the insertion time is increased.
For example, as shown in Patent Document 1, there is a method using a pull-in mechanism in which a tubular film is called a latching claw and is attached to a tubular body while expanding its diameter. However, it is necessary to have a plurality of mechanisms for expanding the hooking claws in the outer circumferential direction in the circumferential direction, and a mechanism for moving the entire mechanism in the axial direction of the tubular body. Further, the mechanism is in contact with the tubular body. It is necessary not to do. Moreover, it is necessary to design the thickness and mechanism of the latching claw that is inserted between the tubular body and the tubular film so as not to exceed the elastic deformation region of the tubular film.
One embodiment of the present invention is directed to providing a method of inserting a tubular body into a tubular film, in which the tubular film is more easily attached to a tubular body having a diameter larger than that of the tubular film.
Another aspect of the present invention is directed to providing an apparatus for inserting a tubular body into a tubular film, which can be more easily attached to a tubular body having a diameter larger than that of the tubular film. It is.

テーパ部２−２の端部の外径ｄ２は、筒状フィルム１の内径ｄ１よりも小さい。
保持部２−１の外径ｄ３は、筒状フィルム１の内径ｄ１よりも大きい。
つまり、テーパ部２−２の端部の外径ｄ２、筒状フィルム１の内径ｄ１、及び保持部２−１の外径ｄ３は下記の関係を有する。
外径ｄ２＜内径ｄ１＜外径ｄ３ Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
1 A device for inserting a tubular body 2 into a tubular film 1 according to the present invention comprises a gripping tool 3 and a lifting mechanism 4. The tube body 2 includes an air supply port 5. The tube body 2 and the support column 7 are disposed on the mount 6. The support column 7 supports the lifting mechanism 4, and the lifting mechanism 4 supports the gripping tool 3.
(1) The tube body 2 has a holding part 2-1 and a taper part 2-2.
The tapered portion 2-2 has an outer diameter continuously reduced from the holding portion 2-1 toward the end portion.
The outer diameter d2 of the end portion of the tapered portion 2-2 is smaller than the inner diameter d1 of the tubular film 1.
The outer diameter d3 of the holding part 2-1 is larger than the inner diameter d1 of the tubular film 1.
That is, the outer diameter d2 of the end portion of the tapered portion 2-2, the inner diameter d1 of the tubular film 1, and the outer diameter d3 of the holding portion 2-1 have the following relationship.
Outer diameter d2 <Inner diameter d1 <Outer diameter d3

（２）把持具３は、筒状フィルム１の第１の端部側の内周面を把持可能である。
把持具３は、筒状フィルム１を把持した状態において、筒状フィルム１の第１の端部とは反対側の第２の端部が、管体２のテーパ部２−２の端部と対向するように、かつ、筒状フィルム１の中心軸と管体２の中心軸とがほぼ同軸になるように配置されている。 (2) The gripping tool 3 can grip the inner peripheral surface of the tubular film 1 on the first end side.
In the state where the gripping tool 3 grips the tubular film 1, the second end opposite to the first end of the tubular film 1 is the end of the tapered portion 2-2 of the tubular body 2. It arrange | positions so that the center axis | shaft of the cylindrical film 1 and the center axis | shaft of the tubular body 2 may become substantially coaxial so that it may oppose.

（３）昇降機構４は、把持具３を下降させることによって下記のことを可能にする。

筒状フィルム１の第１の端部とは反対側の第２の端部が、管体２のテーパ部２−２の端部と対向するように、かつ、
筒状フィルム１の中心軸と管体２の中心軸とがほぼ同軸になるように配置された状態を維持して、
管体２と把持具３とを相対的に接近させ、テーパ部２−２を筒状フィルム１に挿入させる。
（４）エアー供給口５から把持具３と筒状フィルム１と管体２とによって構成される空間の圧力を加圧させるためのエアーが供給される。 (3) The elevating mechanism 4 enables the following by lowering the gripping tool 3.
The cylindrical film 1 gripped by the gripping tool 3 is
The second end opposite to the first end of the tubular film 1 is opposed to the end of the tapered portion 2-2 of the tubular body 2, and
Maintaining the state where the central axis of the tubular film 1 and the central axis of the tubular body 2 are arranged substantially coaxially,
The tubular body 2 and the gripping tool 3 are relatively approached, and the tapered portion 2-2 is inserted into the cylindrical film 1.
(4) Air for increasing the pressure of the space formed by the gripping tool 3, the tubular film 1, and the tubular body 2 is supplied from the air supply port 5.

次に、具体的な工程について図１および図２を用いて示す。
把持具３を筒状フィルム１の第１の端部に挿入した状態にて、把持具３を外周方向に拡径させることで筒状フィルム１の内周面を円筒状に把持する。（図２（ａ）） Next, specific steps will be described with reference to FIGS.
With the gripping tool 3 inserted into the first end of the tubular film 1, the gripper 3 is expanded in the outer peripheral direction to grip the inner peripheral surface of the tubular film 1 in a cylindrical shape. (Fig. 2 (a))

筒状フィルム１の第１の端部とは反対側の第２の端部が管体２の該テーパ部２−２の端部と対向するように、かつ、筒状フィルム１の中心軸と管体２の中心軸とをほぼ同軸に配置する。次に、把持具３を昇降機構４によりテーパ部２−２に相対的に近接させて、筒状フィルム１の第２の端部側の端面を、管体２のテーパ部２−２に接触させる。（図２（ｂ））   The second end opposite to the first end of the tubular film 1 is opposed to the end of the tapered portion 2-2 of the tubular body 2, and the central axis of the tubular film 1 The central axis of the tube body 2 is arranged substantially coaxially. Next, the gripping tool 3 is moved relatively close to the taper portion 2-2 by the lifting mechanism 4, and the end surface on the second end side of the tubular film 1 is brought into contact with the taper portion 2-2 of the tubular body 2. Let (Fig. 2 (b))

次に、管体２に設けられたエアー供給口５から加圧エアーを供給して、把持具３と筒状フィルム１と管体２とによって構成される空間内の圧力を高めて、筒状フィルム１を拡径させる。（図２（ｃ））   Next, pressurized air is supplied from an air supply port 5 provided in the tubular body 2 to increase the pressure in the space constituted by the gripping tool 3, the tubular film 1 and the tubular body 2. The film 1 is expanded in diameter. (Fig. 2 (c))

また、拡径させる別の方法として、エアー供給口５を用いず、昇降機構４を下降するだけで空間の内部容積を圧縮させることにより空間の圧力を上昇させて筒状フィルム１を拡径させる方法がある。この方法においては、把持具が、把持具と筒状フィルムと管体とによって構成される空間を、実質的な閉空間とし得る形状を有することが必要である。   Further, as another method of expanding the diameter, the cylindrical film 1 is expanded by increasing the pressure of the space by compressing the internal volume of the space only by lowering the elevating mechanism 4 without using the air supply port 5. There is a way. In this method, it is necessary for the gripping tool to have a shape that can make the space formed by the gripping tool, the tubular film, and the tubular body a substantially closed space.

「実質的な閉空間」とは、下記のような密閉性を有する空間を意味する。
すなわち、管体のテーパ部を、筒状フィルムの第２の端部側に相対的に挿入し、該空間の体積を減少させることによって、該空間の圧力を、筒状フィルムの内径を円筒部の外径ｄ３よりも大きくし得るように上昇させられる程度の密閉性を有する空間である。完全に密閉された空間であることを要しない。 The “substantially closed space” means a space having the following sealing properties.
That is, by inserting the taper portion of the tubular body relatively to the second end side of the tubular film and reducing the volume of the space, the pressure of the space is changed to the inner diameter of the tubular film. It is a space having a sealing property to the extent that it can be raised to be larger than the outer diameter d3. It does not require a completely sealed space.

この空間内の圧力が上昇している状態において、筒状フィルム１の第２の端部を、管体２の保持部２−１方向に相対的に移動させることにより、筒状フィルム１に管体２を挿入し、筒状フィルム１を管体２の保持部２−１に装着する。
このとき、筒状フィルム１の下端部と管体２との境界では、空間内の上昇している圧力によって、筒状フィルム１の第２の端部と管体２のテーパ部２−２との間から該空間の加圧されたエアーの一部がリークしている状態となる。従って、筒状フィルム１の内周面と管体２の外周面との間には空気の層が存在し、筒状フィルム１の内周面と管体２の外周面とは非接触状態となっている。
そして昇降機構４によって把持具３を、管体２の保持部２−１に向けて相対的に移動させることにより、管体２を筒状フィルム１にスムーズに挿入することができる。（図２（ｄ）） In a state where the pressure in the space is rising, the second end portion of the tubular film 1 is moved relatively to the holding portion 2-1 direction of the tubular body 2, so that the tube is attached to the tubular film 1. The body 2 is inserted, and the tubular film 1 is attached to the holding part 2-1 of the tube body 2.
At this time, at the boundary between the lower end portion of the tubular film 1 and the tubular body 2, the second end portion of the tubular film 1 and the tapered portion 2-2 of the tubular body 2 are caused by the rising pressure in the space. A part of the pressurized air in the space is leaking from between. Therefore, an air layer exists between the inner peripheral surface of the tubular film 1 and the outer peripheral surface of the tubular body 2, and the inner peripheral surface of the tubular film 1 and the outer peripheral surface of the tubular body 2 are in a non-contact state. It has become.
The tube 2 can be smoothly inserted into the tubular film 1 by relatively moving the gripping tool 3 toward the holding portion 2-1 of the tube 2 by the lifting mechanism 4. (Fig. 2 (d))

内径がｄ１の筒状フィルムを用意し、前記の方法を用いてエンドレスベルト形状の基体を有する電子写真用ベルトを製造することができる。
具体的には、前記の方法を用いて管体を筒状フィルムに挿入した状態において、管体の外周面に装着された筒状フィルムの外周面に表面層形成用塗料の塗膜を形成することによってエンドレスベルト形状の基体を有する電子写真用ベルトを製造することができる。
また、管体の外周面に装着された筒状フィルムの外周面に表面層形成用塗料の塗膜を形成した後に、該塗膜の表面を処理するとしてもよい。
また、前記の方法を用いて管体を筒状フィルムに挿入した状態において、管体の外周面に装着された筒状フィルムの外周面に表面層形成用塗料の塗膜を形成することなく、管体の外周面に装着された該筒状フィルムの外周面を処理するとしてもよい。 A cylindrical film having an inner diameter d1 is prepared, and an electrophotographic belt having an endless belt-shaped substrate can be manufactured using the above-described method.
Specifically, in the state where the tubular body is inserted into the tubular film using the above method, a coating film of the surface layer forming paint is formed on the outer circumferential surface of the tubular film mounted on the outer circumferential surface of the tubular body. Thus, an electrophotographic belt having an endless belt-shaped substrate can be manufactured.
Moreover, after forming the coating film of the coating material for surface layer formation in the outer peripheral surface of the cylindrical film with which the outer peripheral surface of the tubular body was mounted | worn, you may process the surface of this coating film.
Further, in the state where the tubular body is inserted into the tubular film using the above method, without forming a coating film of the surface layer forming paint on the outer circumferential surface of the tubular film attached to the outer circumferential surface of the tubular body, You may process the outer peripheral surface of this cylindrical film with which the outer peripheral surface of the tubular body was mounted | worn.

管体２は、材質がアルミニウム、内部は中空構造、全長７００ｍｍ、テーパ部２−２の端部外径ｄ２ ２３０ｍｍ、保持部２−１の外径ｄ３ ２５１ｍｍ、テーパ部２−２の呼込み角６０°で構成されている。また、管体２は、中空内部に圧縮エアーを供給するためのエアー供給口５を具備している。   The tube 2 is made of aluminum, the inside is a hollow structure, the overall length is 700 mm, the outer diameter d2 of the tapered portion 2-2 is 230 mm, the outer diameter d3 of the holding portion 2-1 is 251 mm, and the pulling angle 60 of the tapered portion 2-2 is 60. It is composed of °. The tube body 2 includes an air supply port 5 for supplying compressed air to the hollow interior.

把持具３は、外周にＯリングを配置しており、また、Ｏリングの内側には、Ｏリングの外径を変化させる機構を有している。この機構は、Ｏリングの外径を縮径時２４８ｍｍから拡径時２５２ｍｍまで変化させることができ、この機構により筒状フィルム１を把持することができる。   The gripping tool 3 has an O-ring arranged on the outer periphery, and has a mechanism for changing the outer diameter of the O-ring inside the O-ring. With this mechanism, the outer diameter of the O-ring can be changed from 248 mm when the diameter is reduced to 252 mm when the diameter is enlarged, and the tubular film 1 can be gripped by this mechanism.

昇降機構４は、１軸ロボットを用いて、把持具３によって把持された筒状フィルム１を、管体２に対して相対的に上下に移動させることができる。昇降機構４は、筒状フィルム１を上下に移動させる際、筒状フィルム１の中心軸と管体２の中心軸とを一致させた状態を維持することができる。
該１軸ロボットの能力は、垂直可搬重量１２ｋｇ、最高速度３８５ｍｍ／秒であった。また、把持具３の停止位置として、あらかじめ下記の３つの位置Ｐ１〜Ｐ３を設定した。
位置Ｐ１：筒状フィルム１を装着する位置（図２（ａ））、
位置Ｐ２：筒状フィルム１の第２の端部側の端面と管体２のテーパ部２−２とが接触する位置（図２（ｂ））、
位置Ｐ３：筒状フィルム１に管体２が完全に挿入される位置（図２（ｄ））。
把持具３が位置Ｐ３に到達したとき、把持具３の下端部と管体２のテーパ部２−２の端部との隙間は０．２〜２ｍｍ程度である。 The elevating mechanism 4 can move the cylindrical film 1 held by the holding tool 3 up and down relatively with respect to the tubular body 2 using a single-axis robot. The elevating mechanism 4 can maintain a state in which the central axis of the tubular film 1 and the central axis of the tubular body 2 coincide with each other when the tubular film 1 is moved up and down.
The ability of the single-axis robot was a vertical load capacity of 12 kg and a maximum speed of 385 mm / sec. In addition, the following three positions P1 to P3 were set in advance as stop positions of the gripping tool 3.
Position P1: Position where the tubular film 1 is mounted (FIG. 2 (a)),
Position P2: a position where the end surface on the second end side of the tubular film 1 and the tapered portion 2-2 of the tubular body 2 are in contact (FIG. 2B),
Position P3: A position where the tubular body 2 is completely inserted into the tubular film 1 (FIG. 2D).
When the gripping tool 3 reaches the position P3, the gap between the lower end of the gripping tool 3 and the end of the tapered portion 2-2 of the tubular body 2 is about 0.2 to 2 mm.

また、図示しないエアー供給手段は、エアー供給口５より、管体２の内部にエアーを注入することができ、エアー供給量は最大６００Ｌ／分までの能力を有している。
次に図１および図２を用いて、管体を筒状フィルムに挿入する一連の工程の詳細を説明する。
まず、図２（ａ）に示すように、筒状フィルム１を装着するための位置Ｐ１に、把持具３を移動し、筒状フィルム１の第一の端部を把持具３に侵入させた状態にて、把持具３を拡径させて筒状フィルム１を円筒形状とし、その状態で担持する。 In addition, an air supply means (not shown) can inject air into the tube body 2 from the air supply port 5 and has a capacity of up to 600 L / min.
Next, details of a series of steps for inserting the tube body into the tubular film will be described with reference to FIGS. 1 and 2.
First, as shown in FIG. 2A, the gripping tool 3 is moved to the position P <b> 1 for mounting the tubular film 1, and the first end of the tubular film 1 is made to enter the gripping tool 3. In the state, the diameter of the gripping tool 3 is expanded to make the cylindrical film 1 into a cylindrical shape and supported in that state.

次に、図２（ｂ）に示すように、筒状フィルム１を担持した状態で把持具３を、位置Ｐ２まで移動させ、筒状フィルム１の第１の端部とは反対側の第２の端部を、管体２のテーパ部２−２に侵入および当接させる。このようにすることで筒状フィルム１と把持具３と管体２とによって一連の空間を形成する。   Next, as shown in FIG. 2B, the gripping tool 3 is moved to the position P <b> 2 in a state where the tubular film 1 is supported, and the second end opposite to the first end of the tubular film 1. Is intruded and brought into contact with the tapered portion 2-2 of the tubular body 2. In this way, a series of spaces is formed by the tubular film 1, the gripping tool 3, and the tubular body 2.

次に、図２（ｃ）に示すように、エアー供給口５より管体２の内部に圧縮エアーを１００Ｌ／分供給し、該空間を内部から外部に向かって加圧することで筒状フィルム１を周方向に拡径する。この状態において筒状フィルム１の内径は管体２の外径より大きい状態を維持している。このとき、筒状フィルム１の下端部と管体２のテーパ部２−２の端部との隙間から空気が排出される。   Next, as shown in FIG. 2 (c), the compressed air is supplied to the inside of the tubular body 2 from the air supply port 5 at 100 L / min, and the space is pressurized from the inside toward the outside to thereby form the tubular film 1. Is expanded in the circumferential direction. In this state, the inner diameter of the tubular film 1 is maintained larger than the outer diameter of the tube body 2. At this time, air is discharged from the gap between the lower end portion of the tubular film 1 and the end portion of the tapered portion 2-2 of the tubular body 2.

この状態において、図２（ｄ）に示すように、筒状フィルム１に管体２を完全に挿入する位置Ｐ３まで、把持具３を移動速度１００ｍｍ／秒にて移動させると、管体２を筒状フィルム１に挿入することができた。
実施例１において、筒状フィルム１の第一の端部を把持具３に侵入させた状態にて把持具３の拡径を開始してから、把持具３の位置Ｐ３への移動を完了するまでに要した時間は、１０秒であった。 In this state, as shown in FIG. 2D, when the gripping tool 3 is moved at a moving speed of 100 mm / second to the position P3 at which the tubular body 2 is completely inserted into the tubular film 1, the tubular body 2 is moved. It could be inserted into the tubular film 1.
In Example 1, after the diameter of the gripping tool 3 is started in a state where the first end of the tubular film 1 has entered the gripping tool 3, the movement of the gripping tool 3 to the position P3 is completed. It took 10 seconds to complete.

［実施例２］
また、筒状フィルム１を拡径させる別の方法として、エアー供給口５からエアーを供給せずに、昇降機構４を下降するだけで筒状フィルム１の内部空間の容積を圧縮することにより該空間の圧力を上昇させて筒状フィルム１を拡径させる方法がある。
この方法であれば実施例１の方法よりさらに高速に管体２を筒状フィルム１に挿入することができる。 [Example 2]
Further, as another method of expanding the diameter of the tubular film 1, the volume of the internal space of the tubular film 1 is compressed by simply lowering the elevating mechanism 4 without supplying air from the air supply port 5. There is a method of increasing the diameter of the tubular film 1 by increasing the pressure in the space.
With this method, the tubular body 2 can be inserted into the tubular film 1 at a higher speed than the method of the first embodiment.

図３に基いて、実施例２において用いられる装置の構成について説明する。
図３に示す装置の構成は、図１に示すエアー供給口５を廃止したことと、エアー排出口８を追加したこと以外は、図１に示す装置の構成と同様である。エアー排出口８は管体２の中空内部の圧力が所定値を超えないように、あらかじめ開口しておく、内部のエアーを排出するための排出口である。エアー排出口８は、開口面積を最大６４００ｍｍ２まで手動にて調整できる構造となっている。 Based on FIG. 3, the structure of the apparatus used in Example 2 is demonstrated.
The configuration of the apparatus shown in FIG. 3 is the same as that of the apparatus shown in FIG. 1 except that the air supply port 5 shown in FIG. 1 is eliminated and an air discharge port 8 is added. The air discharge port 8 is a discharge port that is opened in advance so as to discharge the internal air so that the pressure inside the hollow of the tube body 2 does not exceed a predetermined value. The air discharge port 8 has a structure in which the opening area can be manually adjusted up to 6400 mm 2 .

次に図４を用いて、筒状フィルムに管体を挿入する一連の工程の詳細について説明する。
まず、図４（ａ）に示すように、実施例１と同様に、筒状フィルム１を装着するための位置Ｐ１に、把持具３を移動し、筒状フィルム１の第一の端部を把持具３に侵入させた状態にて、把持具３を拡径させて筒状フィルム１を円筒形状とし、その状態で担持する。 Next, the details of a series of steps for inserting the tubular body into the tubular film will be described with reference to FIG.
First, as shown in FIG. 4A, as in Example 1, the gripping tool 3 is moved to the position P1 for mounting the tubular film 1, and the first end of the tubular film 1 is moved. In a state where the gripping tool 3 is invaded, the gripping tool 3 is expanded in diameter to form the cylindrical film 1 in a cylindrical shape and supported in that state.

次に、図４（ｂ）に示すように、昇降機構４により把持具３を移動速度３００ｍｍ／秒にて位置Ｐ１から位置Ｐ３まで移動させるために、把持具３の下降を開始した。このとき、筒状フィルム１に管体２を移動速度（相対速度）３００ｍｍ／秒で侵入させると、筒状フィルム１と把持具３と管体２とによって構成された空間の圧力は瞬時に高まり、筒状フィルム１の内径が管体２の外径より大きい状態に拡径される。このことにより、筒状フィルム１に管体２をスムーズに挿入することができた。   Next, as shown in FIG. 4 (b), in order to move the gripping tool 3 from the position P1 to the position P3 at a moving speed of 300 mm / second by the lifting mechanism 4, the gripping tool 3 starts to descend. At this time, when the tubular body 2 enters the tubular film 1 at a moving speed (relative speed) of 300 mm / second, the pressure in the space formed by the tubular film 1, the gripping tool 3 and the tubular body 2 increases instantaneously. The inner diameter of the tubular film 1 is expanded to be larger than the outer diameter of the tube body 2. As a result, the tubular body 2 could be smoothly inserted into the tubular film 1.

また、このとき、該空間の圧縮された空気は、筒状フィルム１の第二の端部（下端部）と管体２のテーパ部２−２の端部との隙間から排出されるが、筒状フィルム１の下降速度が速いと排出が間に合わなくなり該空間の圧力がさらに上昇する。そして、該空間の圧力が所定値を超えると昇降機構４に過剰な負荷がかかって停止してしまう。そこで、該空間の圧力が所定値を超えないように、あらかじめエアー排出口８を開口しておくことで、該空間の圧力を上昇させることと昇降機構４に過剰な負荷がかかることを回避することが両立できた。この時のエアー排出口８の開口面積は４００ｍｍ２であった。
実施例２において、筒状フィルム１の第一の端部を把持具３に侵入させた状態にて把持具３の拡径を開始してから、把持具３の位置Ｐ３への移動を完了するまでに要した時間は、４秒であった。 At this time, the compressed air in the space is discharged from the gap between the second end (lower end) of the tubular film 1 and the end of the tapered portion 2-2 of the tubular body 2, When the descending speed of the tubular film 1 is fast, the discharge cannot be made in time, and the pressure in the space further increases. When the pressure in the space exceeds a predetermined value, the lifting mechanism 4 is overloaded and stopped. Therefore, by opening the air discharge port 8 in advance so that the pressure in the space does not exceed a predetermined value, it is possible to avoid increasing the pressure in the space and applying an excessive load to the lifting mechanism 4. I was able to achieve both. The opening area of the air discharge port 8 at this time was 400 mm 2 .
In Example 2, after the diameter of the gripping tool 3 is started in a state where the first end portion of the tubular film 1 is inserted into the gripping tool 3, the movement of the gripping tool 3 to the position P3 is completed. It took 4 seconds to complete.

なお、筒状フィルム１を管体２より脱型させるときは、筒状フィルム１が管体２から離れる方向に移動する（管体２が停止した状態で、筒状フィルム１が上昇する）ため、筒状フィルム１と管体２と把持具３とによって構成された空間の体積が増加する。すると、該空間の圧力が減少して筒状フィルム１が内側に凹んで筒状フィルム１に折れキズが発生してしまう。そこで、エアー排出口８の開口面積を全開放の６４００ｍｍ２とすることで、該空間の圧力と大気圧との間に差が無くなり、筒状フィルム１が内側に凹んだりせず、円筒状を維持した状態で脱型することができた。 When the tubular film 1 is removed from the tubular body 2, the tubular film 1 moves in a direction away from the tubular body 2 (the tubular film 1 rises in a state where the tubular body 2 is stopped). The volume of the space formed by the tubular film 1, the tubular body 2, and the gripping tool 3 increases. Then, the pressure in the space decreases, the tubular film 1 is recessed inward, and the tubular film 1 is bent and scratched. Therefore, by setting the opening area of the air discharge port 8 to 6400 mm 2 that is fully open, there is no difference between the pressure of the space and the atmospheric pressure, the cylindrical film 1 is not recessed inside, and the cylindrical shape is It was possible to remove the mold while maintaining it.

［比較例］
比較例について、図１を基に補足を加えながら説明する。
従来の技術では、管体２を筒状フィルム１に挿入させるためには、筒状フィルム１の第二の端部（下端部）を把持して管体２側に引き込む機構が必要となる。
具体的には、筒状フィルム１の第二の端部を円筒状に保ちながら、外周方向に複数の位置において拡径するための拡径機構（以下「拡径機構」と記載する。）を配置しており、また、この拡径機構は、昇降機構によって筒状フィルム１の第二の端部とともに昇降する。
つぎに、管体を筒状フィルムに挿入する一連の工程を説明する。 [Comparative example]
A comparative example will be described with reference to FIG.
In the prior art, in order to insert the tubular body 2 into the tubular film 1, a mechanism for gripping the second end portion (lower end portion) of the tubular film 1 and drawing it into the tubular body 2 side is required.
Specifically, a diameter expansion mechanism (hereinafter referred to as “a diameter expansion mechanism”) for expanding the diameter at a plurality of positions in the outer circumferential direction while keeping the second end of the cylindrical film 1 in a cylindrical shape. Moreover, this diameter expansion mechanism raises / lowers with the 2nd edge part of the cylindrical film 1 by the raising / lowering mechanism.
Next, a series of steps for inserting the tubular body into the tubular film will be described.

拡径機構を筒状フィルム１の第二の端部の内側に侵入させて、筒状フィルム１の内径ｄ１が管体２の外径ｄ３よりも大きくなるように、筒状フィルム１を拡径する。
その状態にて、筒状フィルム１とともに、該拡径機構を管体２のテーパ部２−２方向に相対的に移動させる（下降させる）ことで筒状フィルム１に管体２を挿入した。
比較例において、筒状フィルム１の第一の端部を把持具３によって拡径を開始し、かつ第二の端部を拡径機構によって拡径を開始してから、把持具３の位置Ｐ３への移動を完了するまでに要した時間は、２０秒であった。
比較例では、筒状フィルム１の下端部が管体２のテーパ部２−２の端部よりも下方に位置している間、筒状フィルム１の内面と管体２の外面とは接触状態にあるため、挿入速度を４０ｍｍ／秒以上にすると筒状フィルム１の下端部が拡径機構から外れてしまった。このため、管体２の筒状フィルム１への挿入速度を４０ｍｍ／秒以上にすることはできなかった。 The diameter of the tubular film 1 is increased so that the inner diameter d1 of the tubular film 1 is larger than the outer diameter d3 of the tubular body 2 by allowing the diameter expanding mechanism to enter the inside of the second end of the tubular film 1. To do.
In this state, the tubular body 2 was inserted into the tubular film 1 by moving (lowering) the diameter expansion mechanism relative to the direction of the tapered portion 2-2 of the tubular body 2 together with the tubular film 1.
In the comparative example, the diameter of the first end of the tubular film 1 is started by the gripper 3 and the diameter of the second end is started by the diameter-expansion mechanism, and then the position P3 of the gripper 3 is set. The time required to complete the movement to was 20 seconds.
In the comparative example, the inner surface of the tubular film 1 and the outer surface of the tubular body 2 are in contact with each other while the lower end portion of the tubular film 1 is positioned below the end of the tapered portion 2-2 of the tubular body 2. Therefore, when the insertion speed is set to 40 mm / second or more, the lower end portion of the tubular film 1 has been removed from the diameter expansion mechanism. For this reason, the insertion speed of the tubular body 2 into the tubular film 1 could not be 40 mm / second or more.
