BACKGROUND OF THE INVENTION
The present invention relates to a yarn bundle forming apparatus and a forming method for converging and forming a yarn into a long yarn bundle. Forms a hollow fiber filtration membrane assembly (hereinafter referred to as a hollow fiber bundle) of a hollow fiber filtration membrane separator used for an artificial kidney or the like that removes waste products in blood by dialysis or filtration, or a drinking water purification device. The present invention relates to a yarn bundle forming apparatus and a forming method.

[Prior art]
A method for forming a bundled yarn bundle in a yarn bundle module in which a yarn guided by a reciprocating movement of a yarn guide portion is wound as a linear yarn bundle between a pair of yarn holding bars arranged in parallel is disclosed in Japanese Patent Laid-Open No. 2001-2001. 252535 publication. As shown in FIG. 6, the yarn holding bar is arranged in a cross shape and is rotated intermittently to continuously perform bundling, yarn bundle module formation, yarn end processing, and end yarn waste processing. The converged yarn bundle wound around the yarn holding bar is allowed to be placed in the yarn holding means while being held by the yarn holding bar at a position opposite to the yarn guide portion, and the tension is relaxed. After being converged by being held by the yarn bundle module transfer means, the yarn bundle module forming means forms the yarn bundle module. After forming the yarn bundle module, the yarn bundle module is transferred to the conveying means by the transfer means that holds the converged yarn bundle. In addition, the end scrap yarn remaining on the yarn holding bar regulates the winding width fitted to the yarn holding bar at a point where the yarn bundle holding bar is rotated 1/4 from the yarn bundle module forming point. A method has been proposed in which the guide plate is removed and the end yarn waste is pulled out from the yarn holding bar.
[0003]
According to this method, the bundled bundle bundle wound around the yarn holding bar is formed on the yarn holding bar and the yarn bundle module is formed, and the bundled and module-formed yarn bundle is transferred without re-holding. By doing so, it is possible to form a high-quality yarn bundle module without any distortion or deformation of the yarn, and it is possible to form a yarn bundle with few end scrap yarns. In addition, by arranging the yarn holding bar in a cross shape and rotating it intermittently, it is possible to continuously perform bundling, module formation, yarn end treatment, end yarn waste treatment at the same place, small installation There is an advantage that productivity can be improved in space.
[0004]
[Problems to be solved by the invention]
However, in the above-described yarn bundle forming method, the productivity can be improved stably when forming the bundle yarn bundle wound as a linear yarn bundle between the pair of yarn holding bars in the yarn bundle module. There were the following problems to plan.
[0005]
In order to form the yarn bundle module in a state where the bundled yarn bundle wound around the yarn holding bar is held on the yarn holding bar, if a trouble occurs in the yarn bundle module forming means and the machine stops, the focusing means must also be stopped. Therefore, the yarn continuously supplied from the previous step to the yarn guide portion while being stopped has a problem that the yarn becomes waste yarn and the yield is poor.
[0006]
In addition, when the tension is relaxed after being deposited on the yarn bundle receiving means while being held by the yarn holding bar, residual stress is generated in the bundled yarn bundle due to friction resistance with the yarn bundle receiving means, which is determined by the yarn bundle module forming means. When cut into dimensions, there is a problem in that the module dimensions vary in the vicinity of the yarn holding bar and in the center between the yarn holding bars.
[0007]
Furthermore, as a method of removing the end waste yarn remaining on the pair of yarn holding bars, after removing the guide plate that regulates the winding width fitted to the yarn holding bar, the end waste yarn is removed from the yarn holding bar. Although it was pulled out by the chuck, there was a problem that the yarn was unwound when pulling out, the guide plate and the chuck were entangled and the guide plate was attached and detached, and the machine stopped frequently.
[0008]
In view of the above problems, the object of the present invention is to form a module having a stable shape and dimensions continuously without causing yarn disturbance or mold deformation in forming a yarn bundle module of a long yarn bundle. And a yarn bundle forming device and a yarn bundle forming method that are highly productive and reliable, minimizing waste yarn generated at a stoppage due to trouble with the end waste yarn means, and a hollow fiber bundle forming device and It is to provide a forming method.

After transfer, one of the yarn holding bars was moved 20 mm to relax the winding tension. Next, the yarn bundle receiving unit was raised and deposited in the yarn bundle receiver, and both ends of the converged yarn bundle were grasped by the grasping chuck at a position 20 mm from the inner ends of the pair of yarn holding bars. Here, the gripping minimum diameter of the gripping chuck was 42 mm at the end bundle diameter, and the gripping force was 700 g.
