Abstract

PURPOSE:To load a hollow yarn in a case in a sterilized state without damaging the hollow yarn by turning the inserting port of a cylindrical case upward, supplying a bundle of hollow yarns, and oscillating the case. CONSTITUTION:A case K is placed on a case supporting part 1 so that the case may not be turned. A guiding part 2 for the bundle of hollow yarns is lowered so that a sealing part 5 may be brought into contact with the upper edge of the case K, and a bundle Y of hollow yarns is supplied. The bundle Y of hollow yarns is slowly moved downward by oscillating the whole body of the case K and the guiding part 2 for the bundle of hollow yarns with an oscillating part 3. After the bundle Y of hollow yarns is inserted in the case K, the oscillation by the oscillating part 3 is completely stopped and the case K wherein the bundle Y of hollow yarns is inserted is removed from the apparatus. A vibrator in common use can be used as the oscillating part 3.

Description

DETAILED DESCRIPTION OF THE INVENTION When manufacturing a hollow fiber membrane separator, the present invention efficiently transmits a hollow light beam having an outer diameter equal to or larger than the inner diameter of the cylindrical case into the cylindrical case. It concerns the method of loading.

Among the steps for manufacturing a hollow fiber membrane separator, such as the 1 artificial kidney, the step of loading the hollow fiber bundle into the case is usually shown in Figures 1 to 3. It was done manually as shown here.

Here, Fig. 1 is a plan view of a hollow luminous flux wrapped around the outer periphery, Fig. 2 is a sectional view of Fig. 1, and Fig. 3 is a cross-sectional view of Fig. 1. FIG. 2 is a longitudinal sectional view showing a state in which a bundle of hollow fibers wrapped around a notebook is loaded into a case. That is, the hollow fiber bundle Y has ends Y/ and Y as shown in Figure 1.2.
// is focused using adhesive tape T, etc., but in conventional chestnut production.

Furthermore, using a sheet S having a width wider than the outer circumference of the hollow fiber bundle Y, one end Y' is left and one end S' of the sheet S protrudes beyond the other end Y'', and the outer circumference is Wrap it around the case shown in Figure 3 so that it is slightly smaller than the inner circumference, and /
- Roll f' - Rub 1 hollow fiber bundle t. Then, the sheet is wrapped around one end of the case from 7' to 7'S' of the hollow fiber bundle.
By inserting the protruding side end portion and gradually advancing the notebook winding 1τ1 inside wall yarn bundle into the case, the hollow fiber bundle Y
is loaded into the case at the desired position of the circle, and then, while holding the end Y' of the hollow fiber bundle Y with one hand, pick one end S' of the sheet S with the other hand, pull the sheet Se, and pull the sheet S.
Finish the job by pulling it out from inside the case. These tasks are usually done manually, so no)
When winding S around the hollow fiber bundle Y, if it is wrapped too tightly, the hollow fibers forming the hollow fiber bundle Y will be deformed, bent, or cut, and if it is wrapped too weakly, it will be forced into the case when inserted into the case. In this case as well, the hollow fibers forming the hollow fiber bundle Y are deformed, bent, and cut, so the work requires a high degree of perpendicularity, which not only reduces work efficiency but also results in many defective products. There was a pause. In addition, in the conventional method 1d above, since everything is done manually, 1) consideration must be given to maintaining sterile conditions, which is required, for example, in the case of a hollow fiber hemodialysis device used as an artificial kidney, i.e. Diagnosis of the health condition of workers before work;
It requires complex steps such as changing clothes upon entry and sterilizing exposed body parts, especially hands.Furthermore, although workers wear thin gloves during work, they must be disinfected at regular intervals and every time they touch other objects. It is necessary to sterilize gloves, and further improvements in operational and sanitary efficiency have been desired.

Therefore, the present inventors solved the drawbacks of the conventional method described above, omitted the manual work as much as possible when loading the hollow fiber bundle into the case, and performed the above work automatically instead of focusing on machine work. As a result of intensive studies with the aim of this, we found that a method of loading the hollow fiber bundle by applying vibration to the hollow case would not damage the hollow fibers or cause fiber breakage, and would facilitate handling under sterile conditions. The inventors have discovered that efficient work can be achieved, and have arrived at the present invention.

That is, when loading a hollow fiber bundle into the cylindrical case of a hollow fiber type membrane separator, the present invention holds the case 111 approximately vertically so that the hollow fiber bundle insertion port faces upward, and inserts the hollow fiber bundle into the hollow fiber bundle. 1lllj of a hollow fiber type membrane separator characterized in that a hollow fiber bundle is supplied to the mouth and vibration is applied to the case.
The present invention will be described below with reference to the drawings.

FIG. 4 is a partial longitudinal sectional side view of the apparatus used in the inventive method. 5 to 7 are partial vertical sectional side views showing the process of implementing the present invention using the apparatus shown in FIG. 4.

The symbols for each part in FIGS. 4 to 7 are common,
1 is a case holding part, 2 is a hollow light guide part, 5 is an oscillation part,
4.5 is a /-ru part, 6 is a positioning part, 7 is a support,
8 is a gear, 9 is a handle, 1o and 11 are anti-rotation holding parts, and 12 is a base. In addition, K in FIGS. 5 to 7 indicates a case, which is a part of the hollow fiber membrane separator, and K / and K / / indicate the ends of the case,
B%B' indicates the separation liquid conduit in case K. Furthermore, Y in Figure 6.7 indicates a hollow fiber bundle, and y/
, x / / indicates the end of the hollow fiber bundle Y.

In the apparatus t shown in FIGS. 4 to 7, a case K is shown below.
A case holding section 1 that holds the case by placing it in a substantially vertical state.
A hollow light guide part 2 is provided above the case holding part 1. Hollow fiber guide section 2 is connected to case holding section 1
It is provided opposite to the case holding part 1 so that the center thereof coincides with the upper end of the case that is left still, and is configured to be movable up and down along the support column 7.

When carrying out the method of the present invention, the case K is first placed on the case holding part 1, and the gear 8 is rotated by moving the handle 9 upward, and the hollow This is done by moving the light beam guide section 2 upward. In the embodiment shown in FIG. 5, the case K is placed on the case holding part 1 with the hollow fiber bundle guide part 2 moved upward.

When the case K is placed on the case holding part 1, the separation liquid conduits B and E' to the case are brought into contact with the anti-rotation holding part 10.11.

Next, by moving the handle 9 downward and rotating the gear 8, the hollow fiber bundle guide part 2 is lowered, and the seal part 5 touches the upper end of the case at ``, and the lower end of the case holds the case. It is pressed against the seal part 4 in the part 1tr-.

between the seal part 5 and the upper end of the case, the seal part 4 and the lower end of the case/, the separated liquid conduits B and E' and the anti-rotation holding part 1o,
11, the hollow fiber bundle Y is placed in the hollow fiber bundle guide section 2.
The embodiment shown in FIG. 6 provides the following.

Thereafter, by transmitting vibration to the entire case and the hollow fiber bundle guide section 2 by the oscillating section 3, the hollow fiber bundle Y inserted into the hollow fiber bundle guide section 2 gradually moves downward. The thing to be careful about when vibrating is that if there is a sudden and significant vibration, one end Y' of the hollow fiber bundle Y will strongly collide with the positioning part 6 provided in the case holding part 1, and the hollow fibers forming the hollow fiber bundle Y will collide. The yarn may be cut, so it is desirable to adjust the vibration inspection depending on the thickness of the case, the number of hollow fibers, and the thickness of the bundle relative to the inner circumference of the case. More preferably, the hollow fiber bundle Y vibrates strongly when it starts to fall, and weakens when the end Y' of the hollow fiber bundle Y approaches the positioning part 6t (or if it is interrupted, the hollow fiber bundle Y vibrates strongly).
reaches the positioning portion 6 without receiving a strong impact due to downward inertia.

Note that the positioning unit 6 is used to determine how far the hollow luminous flux Y inserted into the case K should reach.
It is constituted by a groove provided in the case holding part 1 at a desired depth.

After the hollow fiber bundle Y is inserted into the case as shown in Fig. 7, the vibration by the oscillating part 3 is completely stopped, and the handle 9 is raised upwards to move the hollow fiber bundle guide part 2 to the upper end of the case. Then, the case K into which the hollow fiber bundle Y has been inserted is removed from the apparatus (1), thereby completing the loading operation of the hollow fiber bundle.

Note that the base 12 in Figs. 4 to 7 can be applied to a wide variety of products with one device by replacing it with another base when the specifications of the case or the hollow fiber bundle Y change. However, it is not intended to be easy to switch.

Note that the inner diameter of the yarn bundle guide section 2 is preferably shaped like a case, and the minimum diameter is 1 to 2M smaller than that of the case 2.

The oscillator filter is a general-purpose generator such as an electromagnetic type ebrake or a rotary pipe rake, which generates minute vibrations to the case and the entire thread bundle guide section 2.
Preferably something that can.

In Figs. 4 to 7, the oscillating part 3 is provided in the case holding part 1, but in the case of 10-10, the oscillating part is provided in the support 7, and the oscillating part 3 is provided in the case holding part 1U directly or via the anti-rotation holding part 1U. It is also possible to apply vibration to the hollow fiber bundle guide section 2.

As explained above, according to the present invention, in addition to the conventional method of manufacturing a hollow fiber type membrane 1'ffi device, which was performed manually, a hollow fiber bundle that is slightly thicker than the inner circumference of the case is inserted into the case. The work can be changed to machine work, which significantly improves productivity and homogenizes the quality of the resulting product.Furthermore, the most important work, the work of directly inserting the hollow fiber bundles by hand, improves productivity significantly. It is possible to eliminate the extremely negative effect of maintaining sterile conditions, which is a concern in the case of sterile conditions, and it is also possible to create an unmanned factory by combining it with automated machinery.
