Bead feeder

摘要

A single bead-shaped piece fed from a storage pipe storing therein a large number of bead-shaped pieces is carried not on a bearing plate but on a support member provided independently from the bearing plate. The support member is arranged movable on the bearing plate in conjunction with forward and backward movement of a feeding member, and also arranged to be moved relative to the feeding member at the time of the forward or backward movement thereof. The support member is provided with a clamping section for clamping the bead-shaped piece, which is adapted to clamp the bead-shaped piece in conjunction with the relative movement of the feeding member and the support member. This permits the bead-shaped piece to be delivered properly from the storage pipe to the sewing position in a stable manner, and hence a sewing machine can reliably sew the bead-shaped piece on a sewing material.

主权项

1. A bead feeder for delivering bead-shaped pieces, comprising:
a bearing plate; a storage pipe storing therein a large number of separate bead-shaped pieces in stacked relation; a feeding member adapted to be reciprocally moved on a top surface of the bearing plate so that the separate bead-shaped pieces are delivered one by one from the storage pipe to a position just beneath a sewing needle of a sewing machine in accordance with forward and backward movement of the feeding member; a support member for carrying, on the bearing plate, a single bead-shaped piece fed from the storage pipe, the support member arranged movable on the bearing plate in conjunction with the forward and backward movement of the feeding member, the support member arranged to be moved relative to the feeding member at the time of the forward or backward movement of the feeding member; and a clamping section comprising a pair of claws for clamping a single bead-shaped piece carried on the support member, the clamping section operative to clamp the bead-shaped piece in conjunction with the relative movement of the feeding member and the support member, the pair of claws being directly mounted on the support member so that the clamping section moves along with the support member in conjunction with the forward and backward movement of the feeding member section.
