Component supplying apparatus and component supplying method

摘要

A component supplying apparatus has a tape guide part for guiding a carrier tape, a blade for entering between a top tape and a base tape, and a first tape press part for facing the carrier tape on an upstream side of a top tape removing position. A first biasing part biases the first tape press part to have the carrier tape held between the tape guide part and the first tape press part and to attain positioning of the carrier tape in thickness direction thereof. A sprocket wheel wedges the carrier tape between the tape guide part and the first tape press part, and a second biasing part presses the carrier tape against the tape guide part by a second tape press part.

1. A component supplying apparatus for feeding in a tape length direction a carrier tape having a base tape having recesses for accommodating components, and a top tape pasted on the base tape so as to cover the recesses while allowing removal of the top tape from the carrier tape, the component supplying apparatus comprising:
a tape guide part for facing a reverse surface of the base tape that is opposed to a main surface on which the top tape is pasted and guiding the carrier tape toward a top tape removing position, a blade having an edge for entering between the top tape and the base tape from a front end side of the carrier tape fed in a tape feeding direction at the top tape removing position, a first tape press part positioned at an upstream side of the top tape removing position in the tape feeding direction and facing the carrier tape on the tape guide part, a first biasing part for directly or indirectly biasing the first tape press part together with the blade toward the tape guide part with the carrier tape held between the tape guide part and the first tape press part so as to allow the carrier tape to be moved in the tape feeding direction, the carrier tape entering from the side of an entrance of a facing region where the tape guide part and the first tape press part face each other on a tape path of the carrier tape, and attaining positioning of the carrier tape in a tape thickness direction relative to the edge of the blade biased together with the first tape press part toward the tape guide part, a sprocket wheel for rotating while engaging feed holes of the carrier tape so as to wedge the carrier tape in the tape feeding direction between the tape guide part and the first tape press part holding the carrier tape, a second tape press part positioned alongside the sprocket wheel and on the side of the entrance of the facing region between the tape guide part and the first tape press part that hold the carrier tape, and facing the main surface of the base tape on the tape guide part, and a second biasing part for biasing the second tape press part toward the tape guide part to press the carrier tape against the tape guide part so as to allow the carrier tape to be moved in the tape feeding direction; wherein the facing region between the tape guide part and the first tape press part includes a tape holding region in which the carrier tape is held between the tape guide part and the first tape press part and a tape introducing region in which a distance between the tape guide part and the first tape press part increases from the tape holding region toward the upstream side of the tape feeding direction; and wherein the sprocket wheel is configured such that teeth of the sprocket wheel start to engage with the feed holes of the carrier tape in the tape introducing region of the facing region where the tape guide part and the first tape press part face each other on the tape path, and disengage from the feed holes in the tape holding region on a downstream side of the tape introducing region in the tape feeding direction.
