Plastic bottle preform sorting process for blow molding plant involves centrifuging preforms on rotating table until they reach outer guide rail which aligns and separates them

Plastic preforms(1) are fed to a sorting unit with a rotating table(55). Centrifugal force created by the table rotation forces preforms radially outwards to a guide rail(62). Preforms are then individually spaced at the outer edge(63) of the table prior to feeding to a blow molding machine. Preforms are pre-sorted between the center point(59) of the table and the second guide rail(62) by a first guide rail(58). From the central area(56) of the table preforms pass through an opening(60) in the first guide rail into the sorting area which is bordered by the second guide rail. Centrifuged preforms(1) become aligned along the perpendicular second guide rail located above the rotating table(55). During alignment the preforms enter a gap between the second rail and the table equal to at least their body diameter. The second rail provides support until an output area(66) is reached at the outer table edge(63). On reaching the outer edge preforms may be supported, e.g. by an additional rail(68 ...

Device for removing and conveying injection-molded piece

A transparent thin bottle-shaped container is produced by means of a technology for biaxial orientation blow molding a cylindrical piece with a bottom from polyethylene terephthalate material. The pieces are molded in numerous large number in each injection molding process of an injection molding machine. The pieces thus formed immediately after the injection molding are held simultaneously in large number at the gates integrally projected therefrom by a base plate moved forward at the front of the mold in the injection molding machine. They are then conveyed to a gate cutting unit provided near the injection molding machine. The gates are cut from the pieces sequentially by the gate cutting unit and are conveyed onto a conveyor. The pieces are gradually cooled from the hot molded temperature during the conveyance and are additionally cooled while being conveyed on an oblique conveyor installed with a cooler to room temperature or lower predetermined temperature.
