Definitions
- the invention relates to a method for combining fibers or threads, in particular temperature-sensitive hollow fibers into a bundle.
- Hollow fibers can be used for carrying out membrane separation processes as a membrane, namely as a hollow fiber membrane. Such hollow fibers are therefore also referred to as membrane fibers. In particular, hollow fiber membranes are used in medical technology. But there are also various other applications known.
- Hollow fiber bundles are used in medical technology z.
- filters for extracorporeal blood treatment procedures e.g. B. used for hemodialysis, Hömo- filtration and hemodiafiltration.
- hollow fiber membranes for dialysis are produced by continuous hollow-fiber spinning plants. The continuously emerging from the hollow fiber spinning hollow fibers are usually batched z. B. on slow-rotating wrapped in bicycles.
- reel devices for receiving hollow fibers known, for. B. with fixed mandrels. The reel wheels have evenly distributed around winding mandrels on which the hollow fibers rest. As a result, the hollow fibers are stretched freely between the mandrels.
- the distances between the mandrels are selected so that between two mandrels a hollow fiber bundle is formed.
- These hollow fiber bundles are wound around by hand with a thin plastic wrapping film, so that the hollow fiber bundle is given a circular cross section with a previously defined, defined diameter.
- the wrapping film is placed around the hollow fiber bundle in such a way that it overlaps. In the overlap area, the wrapping film is then manually fixed with adhesive tape. Once the hollow fiber bundle is fixed in this way, it is again cut by hand with a cutter to the desired length. Finally, the hollow fiber bundle is introduced into a cylindrical filter cartridge. After insertion of the hollow fiber bundle, the winding film is removed from the hollow fiber bundle and disposed of.
- Such production processes are described, for example, in US Pat. No. 4,276,687.
- the object of the present invention is to automate the combination of hollow fibers into a bundle by means of a winding film. Another object of the present invention is to prevent damage to the delicate hollow fibers during automatic fixation of the wrapping film.
- this object is achieved by a method according to claim 1.
- This procedure consists of the following steps:
- the fixing by adhesive strips is replaced by an automatic welding process, preferably an automatic heat pulse welding process.
- the edge of the winding film is turned towards the hollow fiber bundle, which lies directly on the hollow fiber bundle.
- the winding film can be folded at its one edge region via a device which is incorporated into the winding device before the film is drawn in. But it is also possible to provide the wrapping film with already vorgefalteter edge.
- the welding of the winding film can be carried out by means of generally known plastic welding processes, preferably by heat impulse welding tools.
- the welding time may be in the range of ⁇ 10 s depending on the selected film materials and film thicknesses and may preferably be about 0.3 to 0.5 s during heat pulse welding. But there may also be other plastic welding methods, such. B. permanently heated tools or laser welding process can be used.
- the overlapping edge regions of the film can preferably be welded together only at spaced-apart points. However, it is also possible to weld the overlapping edge regions of the film together by means of a continuous weld seam or several continuous weld seam sections.
- Part of the invention is also a hollow fiber bundle, which is produced by the aforementioned method.
- a housing which can be, for example, a dialyzer housing
- a wrapping film is wound around the hollow fiber bundle, which is turned inwards towards the hollow fibers at its edge region resting on the hollow fiber bundle.
- FIG. 1 shows a schematic representation of a method step in the production of a hollow-fiber bundle
- FIG. 2 shows a representation according to FIG. 1 according to the method according to the invention
- FIG. 3 a schematic representation of a welding tool, as it can be applied in the inventive method
- Figure 4 a perspective view of a hollow fiber bundle.
- FIG. 1 shows a section through a wound-up membrane fiber strand 10 around which a winding film 12 is wound.
- the bundle resulting from the winding is compressed to a specific packing density.
- the bundle receives a defined bundle diameter, so that the bundle later in a not-shown here filter housing, for. B. can be formed in a dialyzer housing.
- the winding film 12 serves as an aid. After introducing the bundle into the dialyzer housing, the winding film is removed again. After winding the hollow fiber bundle, the wrapping film must be fixed.
- a welding tool 14 which is shown for example in Figure 3.
- This is a heat pulse welding tool in which an electrical conductor is heated. This heating up happens within a very short time.
- the welding time is in the range of about 0.3 to 0.5 seconds. In FIG. 3, the welding area is indicated at 16.
- the difficulty in welding thin foils with a heat pulse welding tool is that the welding process is parameterized correctly. If the welding process has not been set correctly or deviations in the boundary conditions underlying the adjustment arise, for example, a different welding process, as shown in FIG. 1, may result in various difficulties. For example, the overlapping area of the film can not be firmly welded. Furthermore, if the welding pulse is too strong, the membrane fibers may also be welded together and adhere to the wrapping film so that they are torn off when the bundle is molded into the dialyzer housing. Furthermore, the membrane fibers can be thermally damaged, so that no flow is possible. Finally, the membrane threads can be melted and solidify uncontrollably.
- welding noses can be formed by the melting of the film, on which the fibers can hang when pulling out the wrapping film or form loops.
- the wrapping film can be safely welded.
- the parameterization of the welding machine is not critical. In the method shown in Figure 1, 10 ° temperature deviation can affect the weld quality, that is, the fibers could be damaged or the weld could not have the required and desired strength.
- FIG. 4 shows a hollow fiber bundle in which the hollow fibers are wrapped by means of the winding film 12. This is welded in its edge region with three spaced welds 20.
