Fiber Bundle Supply Device

Abstract

This fiber bundle supply device ( 32 ) is provided with: plural bobbin holder shafts each of which supports a bobbin (B) around which a fiber bundle (F) is wound; and a turntable ( 323 ) on which the bobbin holder shafts are arranged in a concentric pattern and which rotates around the central axis (C) of said concentric circle, wherein the bobbin holder shafts are configured from at least a first bobbin holder shaft ( 321 ) which supports a first bobbin (B 1 ), and a second bobbin holder shaft ( 322 ) which supports a second bobbin (B 2 ). If the fiber bundle (F) wound around the first bobbin (B 1 ) has been unwound and little remains, by rotating the turntable ( 323 ) and splicing the fiber bundle (F) of the first bobbin (B 1 ) and the fiber bundle (F) of the second bobbin (B 2 ), unwinding of the fiber bundle (F) wound around the second bobbin (B 2 ) is started.

1 . A fiber bundle supply device comprising:
 plural bobbin holder shafts each of which supports a bobbin around which a fiber bundle is wound; and   a turntable on which the bobbin holder shafts are arranged in a concentric pattern and which rotates around the central axis of said concentric circle,   characterized in that   the bobbin holder shafts are configured from at least a first bobbin holder shaft which supports a first bobbin, and a second bobbin holder shaft which supports a second bobbin, wherein   if the fiber bundle wound around the first bobbin has been unwound and little remains, by rotating the turntable and splicing the fiber bundle of the first bobbin and the fiber bundle of the second bobbin, unwinding of the fiber bundle wound around the second bobbin is started.   
     
     
         2 . The fiber bundle supply device according to  claim 1 , characterized in comprising a first fiber bundle guide and a second fiber bundle guide which are installed on the turntable and which rotate with the turntable, wherein
 when the turntable starts rotation, the first fiber bundle guide guides the fiber bundle unwound from the first bobbin to be restricted in a prescribed trajectory,   and when the rotation of the turntable is terminated, the second fiber bundle guide superposes the end portion of the fiber bundle wound around the second bobbin on the fiber bundle unwound from the first bobbin.   
     
     
         3 . The fiber bundle supply device according to  claim 1  characterized in comprising a splicing device which splices the fiber bundle of the first bobbin and the fiber bundle of the second bobbin together, wherein
 the splicing device splices the overlapped portion of the fiber bundle of the first bobbin and the fiber bundle of the second bobbin. 
 
     
     
         4 . The fiber bundle supply device according to any one of  claim 1 , characterized in comprising a cutter device which cuts the fiber bundle unwound from the first bobbin, wherein
 the cutter device cuts the fiber bundle unwound from the first bobbin such that necessary and sufficient bonding strength is obtained when all of the overlapped portion of the fiber bundle is spliced.
