従来より知られている。A method of fixing the ends of hollow fibers with a fixing member, particularly a method of bundling a large number of hollow fibers and loading them into a cylindrical member, and fixing the ends of the hollow fiber bundle at a predetermined position within the cylindrical member with a fixing member. In this process, liquid raw resin for forming the fixing member is injected into the space 1 formed between each bundled hollow fiber and between the hollow fiber and the inner wall of the cylindrical member, and the raw resin flows out from a predetermined fixing position. Conventionally, a method of fixing the hollow fiber bundle with resin while preventing this by applying centrifugal force to the end of the hollow fiber bundle to be fixed has been known.

液肥または気密に固定する方法である。Specifically, in this centrifugal resin fixing method, for example, a cylindrical member loaded with a hollow fiber bundle is fixed to a horizontally or vertically rotating rotor or its arm, and the end of the hollow fiber bundle is fixed with a resin. In order to prevent the liquid raw material resin from leaking from the end of the cylindrical member, a fixing jig is installed to prevent the liquid resin from leaking from the end of the rotor. The resin container passed through the pipe is filled with liquid raw material resin, the rotor is rotated in this state, and by the action of centrifugal force accompanying this rotation, each hollow at the end of the hollow fiber where the liquid raw material resin is to be fixed from the resin container is moving the resin between the fibers and between the hollow fiber and the inner wall of the cylindrical member, and holding the resin there until the resin is cured and formed as a fixed member;
This is a method in which the ends of the hollow fiber bundle are fixed in a predetermined position within a cylindrical member using a fixing member in a liquid or airtight manner.
しかしながら、上述した遠心式樹脂固定法は、次のよう
な問題点を有している。However, the above-described centrifugal resin fixation method has the following problems.

こ困難である。That is, the cylindrical members are stacked and attached to the rotor,
Alternatively, when carrying out this centrifugal resin fixing method by arranging cylindrical members radially around the rotor's rotation axis, the centrifugal resin obtained by rotation of the rotor is Supplying a fixed amount of liquid raw resin to each of the genus of cylindrical members through the resin supply pipes due to the action of force may cause variations in the length of each supply pipe or the mounting position of the cylindrical members, etc. Due to variations in the centrifugal force acting on the main raw material resin due to errors in
This is difficult.

とされる。Moreover, if a liquid type resin that solidifies over time is used as the raw material resin for the fixing member, the resin will solidify and remain in the resin supply pipe, so the resin will solidify and remain in the resin supply pipe. A complicated work to remove the resin is required.
また、該パイプにはある程度の長さが必要とされるため

因となっている。In addition, since the pipe requires a certain length, a large amount of resin solidifies and remains in the vibrator and is discarded, and furthermore, the resin supply pipe must be disposable. This is one of the reasons for the increase in product costs.

状態が得られないという欠点もある。On the other hand, when performing the centrifugal resin fixing method by rotating the cylindrical member in the horizontal direction, the end face of the liquid resin filled in the cylindrical member on the rotation center axis side where the end of the hollow fiber bundle to be fixed is located. However, from the relationship between gravity and centrifugal force, the following formula 1: % formula % () W: Vector of gravity (kg) Day: Vector of centrifugal force (kg) It solidifies with an inclination of 0 degrees, and in that state. There is also a drawback that a fixing member is formed and the hollow fiber cannot be properly fixed by the fixing member.

To make it as small as possible, increase the rotation speed of the rotor and increase the centrifugal force, but this requires further increasing the strength of the machine, and if too much centrifugal force is applied, the The raw material resin easily enters the interior of the hollow fibers, and the raw material resin that can be used is limited.

＋２ｂを常に形成することができる。During this centrifugal treatment in the method of the present invention, the buckets Ha and Ilb rotate while freely tilting at an angle depending on the balance between centrifugal force and gravity, so that the liquid raw resin 12a that has moved into the case 2 is The force acting on the surface 4a facing the rotation center is always perpendicular to the resin surface, so that the fixing member +2b having an end surface perpendicular to the direction in which the hollow fibers 1 are arranged can always be formed.

脂の選択性は大きく拡大されている。Therefore, in the method of the present invention, there is no need to use a large centrifugal force in order to reduce the inclination angle θ in the two-stroke as described above. Instead, it can be carried out using, for example, a commercially available general centrifuge, and the selectivity of the liquid raw material resin that can be used has been greatly expanded.

ース２を得ることができる。When the desired hardening state of the liquid raw material resin 12a is obtained in the case 2, the centrifugation process is completed, and the case 2 is taken out from the buckets Ila and 11b while being integrated with the fixing jig 3. While the resin is sufficiently cured by leaving it alone for a period of time, remove the case 2 from the fixing jig, and fix the hollow fiber bundle end with the fixing member +2b as shown in Fig. 1(e). A cylindrical case 2 fixed to the inner surface can be obtained.

業が非常に簡略化されており、能率良〈実施できる。The method of the present invention described above can be carried out with a simple device such as a centrifuge with a simple configuration, and can be carried out by attaching a case loaded with hollow fibers to a fixing jig, or by attaching a case loaded with hollow fibers to a fixing jig. The work involved in the process is extremely simplified and can be carried out efficiently, as it is very easy to store it inside.

材形成用の原料樹脂を使用することができる。In particular, the fixing jig used in the present invention has a resin reservoir part,
They are provided independently in close proximity to the ends of the hollow fiber bundles to be fixed, and therefore, in snowmaking using the conventional method, the ends of the hollow fiber bundles to be fixed from the resin container are In contrast, in the method of the present invention, it is extremely difficult to supply a fixed amount of liquid raw material resin to each of the hollow fiber bundle ends from a pair of independent resin reservoirs provided at the ends of the hollow fiber bundle. It is possible to constantly supply a predetermined amount of liquid raw material resin, and resin fixation can be carried out with high precision. In addition, since the distance between the resin reservoir and the end of the hollow fiber bundle to be fixed is extremely shortened, the resin is solidified in the small hole that communicates between the resin reservoir and the case mounting part. The amount of residual resin is also extremely small, and the method of the present invention allows efficient use of the raw material resin for forming the fixing member.

のパイプを使い捨てにするようなことはなくなった。Moreover, the small hole for supplying the raw material resin is short and has a relatively simple shape, and moreover, the small hole surface is preferably made of a material with good peelability, so that it solidifies inside the small hole. The fixing jig can be reused by simply pulling out the residual resin from inside the fixing jig using a tool such as a bench, which greatly simplifies the work for reusing the device. In addition, pipes for supplying raw material resin are no longer disposable as in the conventional method.
更に、固定部材の遠心処理における回転中心に向いた端

糸を良好にケース内に保持固定することかできる。Furthermore, the end face of the fixing member facing the center of rotation during centrifugal processing is formed perpendicular to the direction in which the neutral system is arranged, so that the hollow fibers can be well held and fixed within the case.
