Abstract

Provided is a gripping device provided with a pair of gripping members that grip a fiber bundle, into which a plurality of fibers are bundled, from opposing sides in a gripping direction perpendicular to the long direction of the fiber bundle. Even if the fiber bundle is gripped with enough force to prevent the fiber bundle from slipping out from between the pair of gripping members and falling, this gripping device prevents fibers in the fiber bundle from being cut thereby. Also provided are a bundling device and a manufacturing device.

　本発明は、多数本の糸を束ねた糸束体を前記糸束体の長手方向に直交する把持方向の互いに対向する側から把持する一対の把持部材を備えた把持装置及びそれを備えた糸束体の集束装置並びに中空糸束の製造装置、特に、中空糸型血液処理装置（例えば、血液透析、血液濾過、血液透析濾過、血漿成分分画、血漿分離等の用途に用いられる中空糸型血液処理装置）用の中空糸束の製造に関する。 The present invention relates to a gripping device including a pair of gripping members for gripping a bundle of bundles of a large number of yarns from opposite sides in the gripping direction orthogonal to the longitudinal direction of the yarn bundle, and a thread including the gripping device Bundled bundling device and hollow fiber bundle manufacturing device, in particular, hollow fiber blood treatment device (for example, hollow fiber type used for hemodialysis, hemofiltration, hemodiafiltration, plasma component fractionation, plasma separation, etc.) The present invention relates to the manufacture of a hollow fiber bundle for a blood processing apparatus.
　多数本の糸を束ねた糸束は、例えば、予め定めた多数本（具体的には１万本程度）の中空糸を束ねた中空糸束として、従来から、血液透析、血液濾過、血液透析濾過、血漿成分分画、血漿分離等の血液処理を行う中空糸型血液処理装置に用いられている。 For example, a bundle of a large number of yarns has been conventionally used as a hollow fiber bundle of a large number of predetermined hollow fibers (specifically, about 10,000) as a hollow fiber bundle, hemodialysis, blood filtration, hemodialysis. It is used in a hollow fiber blood processing apparatus that performs blood processing such as filtration, plasma component fractionation, and plasma separation.
　多数本の中空糸を中空糸束に束ねる方法としては、従来から、連続的に製造されて長手方向に沿って移動してくる中空糸を集合させた中空集合糸束を、回転する多角形状のリール（例えば六角形のカセ枠）の周囲に掛け渡して環状の中空集合糸束を形成し、形成した中空集合糸束を所定長さに切断することで所定長さの中空糸束体に束ねる製造装置が知られている。 As a method of bundling a large number of hollow fibers into a hollow fiber bundle, conventionally, a hollow aggregate yarn bundle in which hollow fibers that are continuously manufactured and move along the longitudinal direction are assembled together is rotated into a polygonal shape. An annular hollow bundle bundle is formed around a reel (for example, a hexagonal cassette frame), and the formed hollow bundle bundle is cut into a predetermined length to be bundled into a hollow fiber bundle body of a predetermined length. Manufacturing equipment is known.

　ところで、糸束体（具体的には中空糸束体）を製造するにあたっては、例えば、糸束体の長手方向に直交する把持方向の互いに対向する側から把持する一対の把持部材を備えた把持装置によって糸束体を把持した状態で該糸束体を各工程に搬送したり、或いは、該糸束体に対して各種加工を行ったりすることがある。 By the way, when manufacturing a yarn bundle (specifically, a hollow fiber bundle), for example, a grip provided with a pair of gripping members that grip from opposite sides in the gripping direction orthogonal to the longitudinal direction of the yarn bundle. The yarn bundle body may be conveyed to each process while the yarn bundle body is gripped by the apparatus, or various processes may be performed on the yarn bundle body.
　この場合、一対の把持部材により糸束体を把持する把持力が弱すぎると、該糸束体が一対の把持部材からすり抜けて落下してしまうという不都合がある。一方、糸束体が一対の把持部材の間からすり抜けて落下することを回避できる程度の把持力で糸束体を把持すると、一対の把持部材による糸束体の把持部分で該糸束体における一部の糸を切断しやすいといった不都合がある。 In this case, if the gripping force for gripping the yarn bundle by the pair of gripping members is too weak, there is a disadvantage that the thread bundle passes through the pair of gripping members and falls. On the other hand, when the yarn bundle body is gripped with a gripping force that can prevent the thread bundle body from slipping through and dropping between the pair of gripping members, the thread bundle body is held by the gripping portion of the yarn bundle body by the pair of gripping members. There is an inconvenience that some yarns are easily cut.

It is an object of the present invention to provide a yarn bundle body converging device and a hollow fiber bundle manufacturing device.

In the gripping device having a pair of gripping members gripped from the two gripping devices, one of the pair of gripping members is provided with two one-side gripping portions provided at predetermined intervals in the longitudinal direction as one gripping member. And having a single other side gripping part positioned between the two one side gripping parts when gripping the yarn bundle with the two one side gripping parts as the other gripping member. If the part that grips the thread bundle body of the two one side gripping parts and the single other side gripping part is concave, the thread bundle body is between the pair of gripping members. Times to slip through and fall Also grips the yarn Tabatai by the gripping force enough to have found that the cutting of the part of the yarn can be suppressed in the yarn Tabatai.
