ABSTRACT:
A method and apparatus for trimming molded hollow plastic articles having flash and a finish for a closure. Articles are moved in succession through the load, deflashing, facing, inspection, rejection and unload stations of a trimming apparatus by vacuum heads. The articles are picked up by vacuum heads and transferred through the stations by intermittent rotation of a turret carrying the vacuum heads. To ensure proper location, each article is picked up in the load station by a vacuum head and continuously engaged by this vacuum head throughout the deflashing, facing and inspection stations and into the unloading station unless rejected and released in the rejection station.
To facilitate loading, unloading and operations in the work stations on the articles, their orientation can be changed from one station to another. To enable variation of the cycle time of the apparatus, the turret and the operating mechanism in the various stations is driven by a common variable speed drive. To enable the apparatus to trim runs of articles of different sizes, the position of the operating mechanism of the various work stations with respect to the vacuum heads for carrying articles can be adjusted.
