PREFORM HANDLING DEVICE, AND BLOW FORMING DEVICE

摘要

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.

1. A preform handling device to which a preform is consecutively supplied in line along a chute, the preform having a flange that protrudes outward at a position away from an open end face of a neck, and being supplied in an inverted state in which the open end face faces downward, the preform handling device comprising:
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 that is rotated, and pushes part of the preform that is situated above the flange 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 that is transferred along a transfer path, the end face guide member supporting and guiding the open end face of the preform that is pushed by the star wheel; and a pair of flange guide members that are provided in the downstream region on either side of the transfer path along which the preform is transferred, the pair of flange guide members supporting and guiding a lower side of the flange of the preform that is pushed by the star wheel.
