  • Publication number: 20230405838
    Abstract: A suction nozzle device includes a large-diameter pipe, a large-diameter nozzle, a small-diameter pipe, a small-diameter nozzle, and a support mechanism for supporting the large-diameter and small-diameter pipes so as to be movable relative to each other. As the large-diameter and the small-diameter pipes move relative to each other, the large-diameter nozzle and the small-diameter nozzle selectively protrude. A nozzle can be selected from nozzles having different diameters, and the flow rate can be varied in accordance with the selection of the nozzle.

  • Patent number: 11564341
    Abstract: A reel holding device includes a first reel support member that includes a first placement member that rotatably supports a first reel and a second reel support member that supports a second reel. The first reel support member is rotatable between a reference position at which a carrier tape of the first reel is supplied to the mounter, and a discharge position for discharging the first reel. By rotating the first reel support member from the reference position toward the discharge position, the first reel drops through an opening of the first placement member and is discharged. When the first reel support member returns from the discharge position to the reference position, the second reel moves through the opening and into the interior of the first placement member.
