- the disclosed tape feeder setup system determines whether or not to automatically return the carrier tape to the reverse direction based on the future use plan and future use frequency of the parts, targeting the tape feeder placed on the placement table. Therefore, it is possible to select only carrier tapes containing parts that are not scheduled to be used and that have a low future use frequency and a low possibility of being used in the near future, and can be returned in the opposite direction. According to this, since the engagement state of the carrier tape with respect to the tape feeder is automatically released, the trouble of changing the setup for removing the reel can be reduced. On the other hand, the carrier tape containing components that are likely to be used in the near future, even if they are not scheduled to be used, is kept loaded in the tape feeder. This eliminates the need for re-setting of reels and re-loading of carrier tapes in the near future, thus reducing labor for setup changes.
