FEEDER

摘要

A feeder is provided with a pushing member that pushes the carrier tape against a rail, an engaging member engageable with indexing holes of the carrier tape, and an interlocking mechanism that moves an engaging member upwards by interlocking with the upwards movement of the pushing member. The engaging member engages with indexing holes of the carrier to restrict the movement of the carrier tape to the insertion section side. The interlocking mechanism separates the engaging member from the indexing holes of the carrier tape by interlocking upwards movement of the engaging member with upwards movement of the pushing member, allowing movement of the carrier tape in the conveyance direction.

主权项

1. A feeder comprising:
a sprocket that engages with indexing holes formed at regular intervals in a conveyance direction of carrier tape, the sprocket rotating so as to index the carrier tape inserted into an insertion section in the conveyance direction along a rail; a pushing member provided moveably in a vertical direction perpendicular to the conveyance direction that pushes the carrier tape against a rail from an initial position to an upstream position; an engaging member that engages with the indexing holes of the carrier tape at a position further to the insertion section side than a contact portion at which the pushing member contacts the carrier tape; and an interlocking mechanism that moves the engaging member up by interlocking with movement up of the pushing member; wherein the engaging member, when a leading end of the carrier tape is positioned at a position further to the insertion section side than the contact portion and the carrier tape is interposed between the engaging member and the rail, engages with the indexing holes of the carrier tape so as to restrict the movement of the carrier tape to the insertion section side, and the interlocking mechanism, when the pushing member is pushing the carrier tape against the rail, releases the engaging member from the indexing holes of the carrier tape, so as to allow movement of the carrier tape in the conveyance direction, by moving the engaging member up by interlocking with movement up of the pushing member.
