Abstract
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.
Claims9
A blow molding apparatus including a blow molding section for blow-molding a preform to form a hollow container, comprising:
- a continuous transport section provided with a loop-shaped transport path for continuously transporting the preform;
- an intermittent transport section for intermittently transporting the preform to the blow molding section, the intermittent transport section being provided above the continuous transport section and apart from the continuous transport section;
- and
- a delivery section for holding a plurality of preforms being transported on the loop-shaped transport path, and delivering the preforms to the intermittent transport section, the delivery section raising the preforms when the delivery section delivers the preforms from the continuous transport section to the intermittent transport section, wherein
- the delivery section is equipped with a cooling device having a plurality of first nozzle members, the respective first nozzle members cooling the respective preforms locally by jetting a cooling fluid from the respective first nozzle members onto an outer surface of the respective preforms such that a single first nozzle member cools a single preform, and
- in the delivery section, while the preforms and the first nozzle members are being raised by the delivery section in synchronization with each other in the same direction, the respective first nozzle members cool the respective preforms such that a predetermined site of each preform is maintained cooled.
