(54) | Cone type bobbin supplying device |
(57) The present invention provides a cone type bobbin supplying device that can separate
one cone type bobbin from a bobbin aggregate (10) in which a plurality of cone type
bobbins are laminated so that one bobbin is fitted into another, the cone type bobbin
supplying device enabling the separated cone type bobbin to be reliably conveyed.
A cone type bobbin supplying device supplies cone type bobbins (11,12,13...) to a
yarn winding device by separating one cone type bobbin from a bobbin aggregate in
which a plurality of cone type bobbins are laminated so that one bobbin is fitted
into another. A separating member (1) includes a round bar portion (1A) having a diameter
slightly smaller than the bore size of a small-diameter head portion of each of the
laminated cone type bobbins and a cradle (1D) that receives the small-diameter head
portion (11A) of the separated bobbin. The round bar portion of the separating member
is inserted into the bobbin aggregate from the small-diameter head portion of the
cone type bobbins so that the round bar portions will not contact with the cradle.
Furthermore, compressed air is jetted from a plurality of air jetting pores formed
in the round bar portion. |
