  • Patent number: 10829315
    Abstract: A molded product conveying device configures to suck a molded product to a rotator rotating about a predetermined rotary axis and to convey the molded product along a rotation orbit. The conveying device includes a pocket disposed along an outer circumference of the rotator, recessed inward and opened outward radially and perpendicularly to the rotary axis, and fed therein with negative pressure to suck the molded product, and a suction bore positioned to confront the pocket at a first end or a second end along the rotary axis of the rotator, opened toward the pocket to be at least partially overlapped with the pocket when viewed along the rotary axis, and fed therein with a negative pressure to suck the molded product.
