BLOW MOLDING DEVICE AND BLOW MOLDING METHOD

摘要

A blow molding device and a blow molding method can implement a compact device, and can reduce cost. The blow molding device includes a heating section (20) that continuously transfers and heats a plurality of preforms (10) that respectively include a neck (11) along a heating transfer path (200) while supporting the plurality of preforms using a plurality of transfer members (210) in an inverted state in which the neck is positioned on the lower side, a blow molding section (40) that simultaneously blow-molds N (N is an integer equal to or larger than 2) preforms that have been heated by the heating section in an upright state in which the neck is positioned on the upper side to form N containers, and an intermittent transfer section (30) that intermittently transfers the N preforms from the heating section to the blow molding section. The intermittent transfer section includes a pitch conversion section (370) that converts the arrangement pitch of the N preforms from a first pitch P1 to a second pitch P2 (P2>P1), and an inversion section (340) that includes N inversion arms (343) that respectively invert the N preforms from the inverted state to the upright state.
