Problems solved by technology

[0017] However, in the methods of Patent Documents 1 and 2, measurement and inspection are automatically carried out while the thread is running, thereby eliminating the need for professional workers and cutting off defective parts. However, these methods assume that one thread runs on one line condition
That is, when two or more threads are running on one thread, if only the defective portion of one thread is cut off, the length of the other threads will change, so it cannot be wound on the same rotating bobbin
Assuming that it is to be wound on the same bobbin no matter what, when cutting off a defective part from a certain thread, it is sufficient to cut off the normal part at the same length from a thread that does not contain defects produced at the same time, but in In this method, manufacturing yield decreases
In addition, Patent Documents 1 and 2 do not propose a method of correcting the final management amount generated in the hollow fiber membrane bundle after cutting off the defective portion.
[0018] In Patent Document 3, although the paper sheet is not manipulated by the thread, the length of the cut-off part is obtained from the roll diameter before and after the removal of the defective part, and the winding amount is corrected so that the length of the paper sheet included in the final product is Become a specification or so
However, like Patent Documents 1 and 2, it is still difficult to apply the method in the case of simultaneously manufacturing a plurality of products with one line.
In addition, the management amount in Patent Document 3 is only the length of the paper sheet, but when manufacturing a high-function final product such as a hollow fiber membrane bundle, as mentioned above, the outer diameter, surface area, weight, etc. must also be managed

Embodiment approach 1

[0068] The first embodiment of the manufacturing apparatus of bundle-shaped products according to the present invention includes an inspection unit, a winding collection unit, a cutting unit, and a collection amount adjustment unit. figure 1 (a) (b) illustrate the embodiment of the inspection unit, the winding recovery unit, and the recovery amount adjustment unit by way of example, figure 2 (a)(b)(c) illustrate the embodiment of the cutting unit.

[0069] exist figure 1 (a) In (b), 10 is a monofilament of the hollow fiber membrane, 11 is a parallel-filament hollow fiber membrane formed by combining multiple monofilaments, 12 is a recovered parallel-filament hollow fiber membrane bundle, and 20 is measurement / inspection 21 is a measuring / checking control mechanism, 22 is a winding recovery device, 23 is a bobbin, 231, 232, and 233 are respectively the No. 1 position of the bobbin, the No. 2 position of the bobbin, and the No. 3 position of the bobbin. Winding recovery contr...

Embodiment approach 2

[0113] The second embodiment of the manufacturing apparatus of bundle-shaped products according to the present invention includes an inspection unit, a cut collection unit, and a collection amount adjustment unit. Figure 7 (a) and (b) illustrate the second embodiment. The inspection unit is composed of a measurement / inspection head 20 and a measurement / inspection control mechanism 21 similarly to the first embodiment. In addition, as will be described later, the recovery amount adjustment unit is constituted by the cut recovery control mechanism 32, and as the cut recovery unit, constitutes a cut recovery unit that cuts and recovers the thread while cutting it to a certain length.

[0114] Such as Figure 7 (a) As shown in (b), it is also possible to use a cut recovery device instead of the winding recovery device of the first embodiment as a recovery component. The doubling hollow fiber membrane 11 is cut into a given length by the cutting tool 31 and recovered to the reco...

Embodiment approach 3

[0120] The third embodiment of the manufacturing apparatus of bundle-shaped products of the present invention includes an inspection unit, a folding collection unit, a cutting unit, and a collection amount adjustment unit. Figure 8 (a) (b) The 3rd Embodiment is illustrated. The inspection unit is composed of a measurement / inspection head 20 and a measurement / inspection control mechanism 21 similarly to the first embodiment. In addition, as will be described later, the recovery amount adjustment unit is constituted by the return and return control mechanism 36, which serves as the return and return unit as a return and return unit that returns and returns the thread while returning it by a certain length.

[0121] Such as Figure 8 (a) As shown in (b), it is also possible to use a folding recovery device instead of the winding recovery device of the first embodiment as a recovery element. The doubling hollow fiber membranes 11 are returned to the rotating turnback gear 34 wi...

Abstract

A manufacturing method for a bundle product (13) comprises: a step for inspecting a plurality of traveling threads (10) by a measurement / inspection head (20) such as a digital camera; a step for winding the threads (10) around a reel (23); and a step for cutting the wound threads (12) by a cutter (40) to obtain the bundle product (13). A measurement / inspection control mechanism (21) such as an image inspection system finds the total surface area of the traveling threads (10) on the basis of the result of the inspection by the measurement / inspection head (20). A winding and collection control mechanism (24) continues winding until the total surface area of the threads (12) wound around the reel (23) exceeds a standard value. The thread (10) is a hollow fiber. A hollow fiber membrane bundle (13) having a total surface area exceeding the standard value can be obtained by this method. The hollow fiber membrane bundle (13) is incorporated in a module for filtering water. This module has sufficient filterability.

Description

technical field [0001] The present invention relates to a method and an apparatus for manufacturing a bundle-shaped product obtained by collecting and winding a yarn continuously running in a longitudinal direction while adjusting the winding amount so as to finally obtain a predetermined amount or more. Background technique [0002] Threads such as fibers, optical fibers, and hollow fiber membranes (hereinafter sometimes simply referred to as "threads") have been used as thread products alone or as final products manufactured with thread as the main component. Utilize and effectively use in various fields and purposes. In particular, many wire bundles obtained by bundling a plurality of wires can greatly increase the performance as a product compared with the case of a single wire, and the wire bundle itself is mainly used as a bundle product or as a bundle product. It is widely used in the final products manufactured from the constituent parts. [0003] Here, as the thre...
