A blow molding apparatus comprises: a continuous transport section provided with a loop-shaped transport path for continuously transporting a preform; an intermittent transport section for intermittently transporting the preform to a blow molding section; and a delivery section for holding the preform being transported on the transport path, and delivering it to the intermittent transport section. The delivery section is equipped with a cooling means for jetting a cooling fluid from a first nozzle member onto an outer surface of the preform to cool the preform locally.

Blow molding apparatus

A blow molding apparatus includes: an injection molding section for injection molding a plurality of preforms at a time; a cooling section for cooling the preforms; a heating section for heating the preforms while continuously transporting them along a transport line; and a blow molding section for blow molding the preforms to form hollow containers. The blow molding section includes a primary blow molding section which is equipped with a heat-treating blow mold and blow molds the preforms moved from the transport line into the heat-treating blow mold to form intermediate molded products, and a secondary blow molding section which is equipped with a final blow mold and blow molds the intermediate molded products moved from the heat-treating blow mold into the final blow mold to form the hollow containers.

In various embodiments, a molded product delivery apparatus or a blow molding machine includes a first transfer member that includes first paired chucks that hold a portion of an outer wall of a neck portion of a molded product, and a second transfer member that includes second paired chucks that hold another portion of the outer wall of the neck portion of the molded product. From a state where the molded product is held by both of the first paired chucks and the second paired chucks simultaneously, by opening one of the first paired chucks and the second paired chucks without interfering with the other, the molded product is delivered between the first paired chucks and the second paired chucks.

Molded product delivery apparatus and blow molding machine

A blow molding machinehas a blow molding section, an ejection section, and a delivery unit. In order to deliver a plurality of containers B to a deviceof a post-process subsequent to the blow molding machine, the delivery unit includes a rail for holding, delivering and guiding the plurality of containers, and an elevation block raised and lowered relative to the rail. The elevation block includes a plurality of blades, an endless member to which the plurality of blades are fixed at a blow molding pitch, and a drive portion for driving the endless member to run.

Blow molding machine

In an embodiment, an injection stretch blow molding device includes an injection molding section that produces N (N is an integer equal to or larger 2) preforms by injection molding, a cooling section that subjects the N preforms transferred from the injection molding section to forced cooling, a heating section that continuously transfers and heats the N cooled preforms, and a blow molding section that subjects the N heated preforms to stretch blow molding in n (n is an integer equal to or larger than 2) operations, the blow molding section simultaneously stretch blow molding M (M=N/n, M is a natural number) preforms among the N preforms into M containers.
