Bobbin changing method and apparatus

摘要

A bobbin changing apparatus for a flyer frame which allows works to freely be performed by attendants at a front side of the flyer frame at any time during the operation of the flyer frame, while eliminating need for providing independent rails for transporting full bobbins and empty bobbins, respectively. Disposed at a front side of a flyer frame (2) is a work platform (35) on which the number of pegs (49) which is twice as large as that of bobbin wheels are mounted with a pitch equal to a half of that of the bobbin wheels (4). Each of the pegs (49) can selectively be disposed at an operative position on a top surface of a cover plate (41) and to a retracted position retracted from the top surface. Further, the pegs can be driven reciprocatively over a distance corresponding to one pitch of the peg array. A bobbin changing mechanism 13 is disposed at a rear side of a bobbin rail 3, while supporting rails are disposed above the flyer frame 2 at the front side thereof so as to be moved up and down by a lift mechanism 7. Bobbin transporting carriers 10 having empty bobbins E for one flyer frame suspended thereof are supported on supporting rails (5, 6). Upon bobbin changing operation, the pegs (49) are disposed at the operative position which allow the full bobbins (F) and the empty bobbins (E) to be exchanged between the bobbin transporting carrier (10) and the bobbin rail by way of the pegs on the work platform (35).
