A device () for optical inspection of parisons () comprises: an illuminator () configured to emit a beam of light directed at a parison () located at an inspection position (); a detector () configured to capture an image () of the parison () interposed between the illuminator () and the detector (), where the illuminator () includes an emission-polarizing filter () configured to generate a polarized light beam, and where the detector () includes a receiving polarizing filter () configured to receive the polarized light beam.

Device for optical inspection of parisons

An apparatus () and a method for optical inspection of parisons () made of thermoplastic material comprises: a conveyor () comprising a pair of lateral, under-flange guidesA for holding each parison by its flange, and configured to transport the parisons () in succession along an inspection path; an inspection station (), located along the inspection path and including at least one inspection camera (), configured to capture image data of a parison () positioned in the inspection station (), wherein the conveyor () has a first operating configuration for transporting parisons () of a first size and a second operating configuration for transporting parisons () of a second size, different from the first size, the conveyor () including at least one adjustment actuator (), configured to move the conveyor () between the first and the second operating configuration.

Device for optical inspection of preforms

An apparatus () for optical inspection of plastic parisons () intended to be blow molded to form containers, comprises a conveyor () for transporting corresponding parisons () along a predetermined path; at an inspection station along the path, each parison () is positioned with its axis () aligned with a longitudinal reference axis. A stationary camera () is provided, with its viewing axis () coincident with the longitudinal reference axis, to view the interior of the parison (); an illuminator () is positioned around the viewing axis () of the camera (), to irradiate the outside surface of a mouth end () of the parison (). The camera () has a wide-angle lens, to capture an image of an inside surface of the mouth end () of the parison (), representing a screw thread () and the identification code () of the parison (), shown in transparency.

Apparatus and method for optical inspection of parisons

A method comprises projecting a light and shade pattern defined by preset optic parameters through a body, detecting an image of the light and shade pattern through the body to obtain a detected image, processing the detected image to highlight any irregularities of the light and shade pattern in the detected image; an apparatus comprises a light-source for projecting a light and shade pattern defined by preset optic parameters through a body, an image-detecting device for detecting an image of the light and shade pattern through the body to obtain a detected image and a processing device for processing the detected image in such a way as to highlight any irregularities of the light and shade pattern in the detected image.
