Abstract: A blow molding device of the invention includes a pair of blow cavity split molds (50A, 50B), a chuck member (80) that chucks a mouth portion (20) and conveys a preform (10A), a blow core mold (70) that includes a tubular portion (71) which surrounds circumferences of the mouth portion and a flange (25) and introduces blow air into the preform, and a pair of projecting members (60A, 60B) which have a halved ring shape and are provided detachably on each upper surface of the pair of blow cavity split molds. Each of the pair of projecting members includes an airtight sealing portion (61) which is in contact with a lower end face of the tubular portion of the blow core mold, and a positioning portion (62) which positions the flange of the preform.

Abstract: A preform conveying device (100) of the invention includes a control unit that detects an arriving time at which a conveyor jig arrives at a reference position based on an output of a first encoder, and commands a second motor to move a conveyor arm to a target position at regular intervals from the arriving time. The target position in each command is a position obtained by adding, to a current position of the conveyor jig which is obtained based on a latest output of the first encoder which was obtained when the command has been issued, a moving distance by which the conveyor jig has advanced during a delay time T which spans from a time when the latest output is outputted from the first encoder to a time when the command is received by the second motor.

Abstract: A preform has a flange that protrudes outward at a neck, and is supplied in an inverted state. A preform handling device includes a star wheel that is configured so that the preform is supplied to each of a plurality of depressions that are formed in an outer circumferential part of a wheel, and pushes the preform to rotationally transfer the preform from an upstream region to a downstream region, an end face guide member that is provided in the upstream region so as to be situated under the preform and that support and guide an open end face of the preform, and a pair of flange guide members that are provided in the downstream region and that support and guide a lower side of the flange of the preform.
