Problems solved by technology

[0008] However, in the packaging method and packaging device described in Patent Document 2, the length of the packaging sheet wound around the fiber bundle in the width direction is limited, and the packaging sheet of the fiber bundle wound with the packaging sheet cannot exceed The overlapping part of one circle is set to be longer than the specified length, and the overlapping part beyond one circle becomes relatively short
In this way, if the overlapping portion of the packaging sheet of the fiber bundle body wound with the packaging sheet beyond one turn is relatively short, there will be a disadvantage that the packaging sheet is easy to detach from the fiber bundle body.

Embodiment Construction

[0068] Hereinafter, embodiments according to the present invention will be described with reference to the drawings. In addition, the embodiment shown below is the example which actualized this invention, and does not have the property which limits the technical scope of this invention.

[0069] figure 1 It is a schematic block diagram showing an example of the manufacturing apparatus 10 of the hollow fiber bundle Bg concerning this embodiment.

[0070] The manufacturing apparatus 10 of the hollow fiber bundle Bg is a dry-type manufacturing apparatus for manufacturing the hollow fiber bundle Bg from the dry hollow fiber Ba, and the manufacturing apparatus 10 includes a bundling device 100, a packing device 200, a cutting device 300, and overall control of the manufacturing device 10. The control part 400 which manages.

[0071]In the manufacturing apparatus 10, several hundred (specifically, 512 to 768) dried hollow fibers Ba transported from the spinning unit 20 are collect...

Abstract

The present invention provides a packaging method and a packaging device for fiber bundles and a manufacturing method and device for hollow fiber bundles. The packaging method and packaging device for fiber bundles are used for winding packaging sheets around bundles of multiple fibers. The fiber bundle body can increase the overlapping portion of the packaging sheet beyond one turn of the fiber bundle body around which the packaging sheet is wound. Regarding the packaging method and packaging device (200) of the fiber bundle (Bd), the packaging sheet (S) is wound around the fiber bundle (Bb) in which a plurality of fibers (Ba) are bundled, and the packaging is With the sheet (S) covering the periphery of the fiber bundle body (Bd), the fiber bundle body (Bd) and the packaging sheet (S) are rotated in the predetermined rotation direction (A2) while the packaging sheet (S) is rotated. ) is wound around the fiber bundle body (Bd).

Description

technical field [0001] The present invention relates to a packaging method and packaging device for a fiber bundle body and a manufacturing method and device for a hollow fiber bundle, in particular to a hollow fiber type blood treatment device (for example, for hemodialysis, hemofiltration, hemodiafiltration, plasma components Production of hollow fiber bundles for hollow fiber type blood processing devices for differentiation, plasma separation, etc. Background technique [0002] Conventionally, a fiber bundle in which a plurality of fibers are bundled, for example, a hollow fiber bundle in which a predetermined number (specifically, about 10,000) of hollow fibers are bundled, has been used for hemodialysis, hemofiltration, and hemodiafiltration. , Plasma fractionation, plasma separation and other blood processing hollow fiber type blood processing device. [0003] A hollow fiber bundle formed by bundling a plurality of hollow fibers is produced by cutting a hollow aggreg...
