Yarn bundling method, dressing method and device

The present invention relates to a method for more tightly bundling yarns composed of a large number of fibrous objects, a method for mounting the bundled body in a cylindrical container, and a device therefor. It is provided. In particular, the present invention provides an improved hollow fiber convergence method, an installation method, and an apparatus suitable for manufacturing a hollow fiber type fluid separator suitable for fluid separation.

Background art

Fluid separators are available in the form of a fluid separation membrane, such as a flat plate, a tube, a hollow fiber, etc., where Φ is the hollow fiber and the membrane area is as large as the size of the case. Because of its large size, the fluid separator itself is compact and has many advantages such as easy operability.In recent years, hollow fiber type fluid separators have become It is becoming mainstream.

The manufacturing process of the hollow fiber type fluid separator consists of (1) making a predetermined number of hollow bundles, (2) storing them in a plastic case, that is, in a cylindrical container, and (3) Using a resin such as urethane, a hollow fiber is bonded and fixed to both ends of the case, and both ends are cut to form a hollow fiber opening, and the fluid distribution plate ( Header (1) is fixed. Regarding the bundle of hollow fiber bundles and the storage in the case, manual methods have been the mainstream than before, and there is a tendency for product quality parachutes to occur, and production efficiency is low. The development of a new method was desired. In particular, it has been strongly desired to efficiently perform a bundle bundled in a compact for accommodating a large number of hollow fiber bundles in a case.

That is, in general, when a predetermined number of hollow fiber bundles are formed, the hollow fiber bundles obtained by the bundling method may have a flat cross-section, a round or square rod-like cross-section. Then, in order to mount the hollow bundle in the case, the cross-sectional shape of the hollow fiber bundle is stored, that is, the cross-sectional shape is almost the same as the cross-sectional shape of the inner surface of the case to be mounted, and the cross-sectional shape is circular. If the cross-sectional shape is elliptical or rectangular, the major and minor diameters or the vertical and horizontal dimensions are almost the same as or slightly smaller than the inner surface of the case. It is necessary to be.

When the hollow fiber bundle is formed, the above conditions are satisfied and the case can be mounted as it is. However, if the above conditions are not satisfied, the shape of the hollow fiber bundle is satisfactorily modified. Must .

Conventionally, the shape of the hollow fiber bundle has been usually corrected almost manually because it is difficult to implement by a machine. Then, the hollow fiber bundle, which has been manually corrected, is further slowly and carefully placed into a cylindrical plastic case by manual work. Was the usual method. But However, if it is performed manually, there are many factors that depend on the skills of the individual workers, so that not only productivity is high, but also the quality of the products must be uneven. The present invention solves the above problems.

Further, in the manufacture of hollow fiber type fluid separators such as hollow fiber type hemodialyzers, the method of mounting a selectively permeable hollow fiber bundle in a cylindrical container for a fluid separator is described as follows. The end of the hollow fiber bundle is tied with a tape, and one by one from one end of the cylindrical container is manually pushed in and out, and a longer string than the cylindrical container is used. After passing one end of the string through the tubular container and attaching one end of the string to the hollow fiber bundle, the other end of the string was pulled in by pulling in.

In these conventional methods, it is necessary for a skilled worker to manually adjust the form of the hollow fiber bundles one by one and insert each into a cylindrical container in a safe manner. However, the production of an efficient hollow fiber type fluid separator with high productivity has been a major issue. Also, when inserting, the bundle of hollow fibers is easily disturbed by friction with the wall of the container, which may cause deterioration such as breakage of the hollow fibers. This was one of the reasons for the decrease in productivity of container manufacturing.

More recently, before installing in a cylindrical container, it is necessary to wrap the hollow fiber bundle in a sheet in a specific state where one side is protruded and the other is protruded. Then, insert the sheet-wound hollow fiber bundle obtained from the bundle into the container from the side where the yarn was cut. A method of pulling out only the sheet from the opposite side (Japanese Patent Application Laid-Open No. 60-47171), or a method using a hollow cylindrical bag with a string attached to one end, and the end of the bundle of hollow yarn bundles at the other end. The operation of enclosing the hollow fiber bundle in a specific contact state was performed in advance, and the encased hollow fiber bundle was introduced into the protective outer cylinder from the person who attached the string, and then the bag was wrapped with the string. A method has been proposed in which only the hollow fiber bundle is removed and the hollow fiber bundle is attached to the outer cylinder (Japanese Patent Application Laid-Open No. 61-86906). However, the operation of wrapping the hollow fiber bundle in advance is complicated, and the process tends to become complicated especially when the hollow fiber bundle is efficiently loaded into the cylindrical container by an automated device. Further improvements are desired.

In particular, it is intended to improve the convergence method of hollow fiber bundles, which is a part of the manufacturing process of a hollow fiber type fluid separator that requires the storage of hollow fiber bundles at high density. .

Further, an object of the present invention is to improve the process of mounting the hollow fiber bundle on the cylindrical container to a method suitable for automatic mechanization, so that the hollow fiber can be more stably and with high productivity. It is intended to make it possible to manufacture mold fluid cones.

BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is a front view showing the structure of a yarn bundling apparatus according to an embodiment of the present invention, and FIG. 2 is a plan view, and a hollow fiber bundle であ as a yarn is a belt means. The endless belt 2, the squeezing jig 3 as squeezing means, and the focusing nozzle 4 as nozzle means are focused into a substantially appropriate shape and mounted in the case 5. It is a sign that it has been released. End lever 2 is driven by rollers 6, 7 or 8. The arrows in the figure indicate the direction of movement of the hollow fiber bundle, belt, or roller.

Immediately, the hollow fiber bundle 1 is supplied to the apparatus of the present invention by supplying the yarn 1 consisting of the hollow fiber bundle almost aligned in parallel to the endless belt 2. At the same speed as Endless Level 2. The endless belt 2 is narrowed down by the drawing jig 3 and the convergence gradually progresses.

As an initial supply method of the hollow fiber bundle 1, the hollow fiber bundle Ί may be gripped by a mouth pot (not shown) and brought near the drawing jig 3, or the roller 8 may be supplied. ₀ Ru possible der be operated synchronously with b Ra 8 rearward and end-less bell Bok 2 installed bell Bok conveyors running at the same speed (not shown) of

As the hollow fiber bundle 1 is converged from a wide state, it may bulge in the height direction, but the bulge is large and the endless belt 2 meshes with In this case, it is also possible to install a press roller or guide 10 as a press means above the yarn 1 at the position where the bundled yarn Ί is buried in the height direction to prevent bulging. . '

By passing through the squeezing jig 3, the endless belt 2 is rolled into a state like seaweed of rolled sushi.

Next, the hollow fiber bundle 1 converged by the drawing jig 3 is finally converged into an appropriate shape by the converging nozzle 4, and then into the case 5 placed in front thereof. It is, of course, necessary to design the shape of the focusing nozzle 4 appropriately for the inner shape of the case 5 in which the hollow fiber bundle 塡 is mounted.
