When winding the hollow fiber bundle Yf around the hollow fiber bundle Yf, if it is wrapped too tightly, the hollow fibers forming the hollow fiber bundle Y will be bent, bent, or cut. In this case as well, the hollow fibers forming the hollow fiber bundle Y may be deformed, bent, or cut, so the work requires a high degree of skill, and not only is the work ability inferior, but also the There was a problem in that defective products were produced.Furthermore, in the conventional method described above, since everything is done manually, it is difficult to maintain sterility, which is required in the case of a hollow fiber hemodialysis machine used as an artificial kidney, for example. This process requires complex steps such as diagnosing the worker's health condition during work e+1, changing clothing when entering and exiting the production area, and sterilizing exposed body parts such as hands. Shisara 1
Although workers wear thin gloves during this work, it is necessary to sterilize the gloves at regular intervals and each time they touch other objects. was.

Therefore, the inventors of the present invention have solved the above-mentioned drawbacks of the conventional method, omitted the manual work as much as possible when loading the hollow light beam into the case, and performed the above work automatically, mainly using mechanical work. As a result of intensive research with the aim of They discovered that it was easy to handle the work in various conditions, and they also developed a device to efficiently carry out the work.

That is, when loading a hollow fiber bundle into a cylindrical case of a hollow fiber type membrane separator, the present invention holds the case substantially vertically so that the hollow fiber bundle insertion port faces upward, and inserts the hollow fiber bundle in the order of li+J. The hollow fiber bundle is supplied to the hollow fiber bundle guide section located above the mouth, and the pressure is reduced in the case described in 1iiJ, and vibration is applied to the case and the hollow fiber guide section to A method for manufacturing a hollow fiber membrane separator (first invention) characterized by inserting the case into a case, and an apparatus for carrying out the above method, wherein the case is inserted into a case with a hollow fiber bundle insertion port. 11 to be upward?

As shown in FIG. 4, the apparatus according to the present invention includes a case holding section 2 that holds a case K substantially vertically in a main body 1. Further, a hollow light beam guiding section 4 is provided above the case holding section 2 via a support 6. By operating the handle 9 and rotating the gear 8, the hollow fiber bundle guide section 4 is moved up and down approximately parallel to the column 3, and the case holding section 2 and the lower end 4' of the hollow light beam guide are moved up and down. You can change or adjust the spacing.

Reference numeral 7 denotes a blind plug provided on the support column 3, which closes the separation liquid conduit P to the case while the case K is held in the recess 10 of the case holding portion 2. The blind stopper 7 is used when the device according to the present invention is used in a case where the separation liquid conduit P having a length of 1 is installed in a different position in the case in which the hollow fiber bundle Y is loaded.
+Position is changed. That is, the four positions of the blind stopper 70 can be changed, thereby providing versatility.

The suction section 5 is operated when the case K is held in the case holding section 2 and air is sucked into the case to reduce the pressure, and is preferably provided at a position communicating with the separated liquid conduit P' below the case. . The suction s5 may be formed by opening a part of the case holding part 2 so as to communicate with the case K at the lower end of the case while holding the case K in the case holding part 2.

In this case, care must be taken not to suck the single fibers forming the hollow fiber bundle Y into the suction section 5.

The case holding section 2 and the hollow fiber bundle guide section 4 described in 01J are connected to the oscillating section 6 or integrated through other parts so that they vibrate regularly or irregularly due to the vibrations generated by the oscillating section 6. It becomes. The oscillating section 6 is preferably a general-purpose vibrator such as an electromagnetic vibrator or a rotary vibrator, which gives slight vibrations to the case and the hollow fiber bundle guide section 4. Note that the oscillation section 6
can also be provided on the support 7.

Next, an example of carrying out the method of the present invention using the apparatus shown in FIG. 4 will be described in detail.

First, the handle 9 in FIG. 4 is rotated upward to rotate the gear 8 to move the hollow fiber bundler interior 4 upward, and then
As shown in FIG. 5, the case K of the hollow fiber membrane separator is placed on the case holding part 2. In this case, the lower end of the case should be
It is desirable to form the case holding part 1 part 2 so as to surround the outer periphery of the case holding part 2.

In the case placed on the case holding part 2, the separation liquid conduit P is inserted into the blind stopper 7 and closed. Although the separation liquid conduit P is generally sealed, outside air may be allowed to flow in depending on the strength with which the suction unit 5 sucks the air inside the case and the falling speed of the hollow fiber bundle Y.

Separate liquid conduit P installed near the bottom end of the case
' is connected to the suction part 5 and is in a state where the air inside the case can be sucked.

After that, the handle 9 is rotated to lower the hollow light guide part 4 and the hollow light guide part ψ1ili4' is fitted into the upper end (hollow fiber bundle insertion opening) K'' of the case, and the hollow fiber bundle Y is inserted into the hollow fiber bundle Y. l+13 is supplied and inserted into the hollow light beam guide section 4 vertically, resulting in the state shown in FIG.
Since it is thicker than the inside of the case, it cannot be easily loaded into the case.Next, the suction part 5e sucks the air inside the case to reduce the pressure inside the case, and the oscillation part 6 suppresses vibration. The case K is attached to the case K via the case holding part 2, and the case K is attached to the support column 3.
By vibrating the hollow fiber bundle guide section 4 via the hollow fiber guide section 4, the hollow fiber bundle Y in the hollow light guide section 4 is gradually lowered into the case without disturbing or damaging each single fiber. The lower end Y' of the inner wall yarn bundle Y reaches the recess 1qt of the case holding portion 2, resulting in the state shown in FIG. The suction part 5 sucks the internal air into the case when the lower end Y' of the hollow fiber bundle Y is d.
It is preferable to stop at the same time when the current reaches 10 mJ or at the reached mJ. This is to prevent the single fibers forming the hollow fiber bundle Y from being sucked into the suction unit 5 by continuing suction even after reaching the point, causing disturbance or damage to the single fibers. The vibration by the oscillator 6 is stopped at the same time or after the lower end Y' of the hollow fiber bundle Y reaches the 1° depression.

As shown in Fig. 7, after loading the hollow fiber bundle Y into the case, turn the handle 9 upward to raise the set hollow fiber bundle guide part 4 and attach it to the upper end of the case. After untying, remove the case K from the blind plug 7, suction part 5, and case holding part 2, and transfer it to another place.

The effects of the present invention are further enhanced by using the hollow fiber bundle guide section 4 as a constriction mechanism such as a conical tube shape and constricting the hollow fiber bundle Y immediately before loading it into the case.

According to the uninvented method and device as described above, the suction section 5
The air inside the case is suctioned to reduce the pressure.
The hollow fiber bundle guide section 4t provided above sucks the supplied hollow fiber bundle Y into the case and lowers it, and also applies vibration to the case K from the first oscillating section 6 to separate the hollow fiber bundle Y and the hollow fiber bundle. Frictional resistance between the yarn bundle guide 4 and the case is reduced, and furthermore, a synergistic effect with the lowering of the yarn's own weight occurs, so the single fibers forming the hollow fiber bundle Y are not damaged and are prevented from bending or bending. Hollow fiber membrane separators can be produced smoothly without any such occurrence.

The present invention is a hollow fiber membrane separator used in artificial kidneys that are used for hemodialysis in living organisms and require extremely high quality accuracy.
1! It is suitable for AT, and has remarkable effects such as significantly reducing the defective rate and significantly improving productivity and quality.
