Method and apparatus for inspecting blow molded containers

   
   

A method and apparatus (16) for inspecting the thickness of conveyed blow molded containers (18) utilizes a laser source (22) for directing a laser beam (24) upwardly from the exterior of the conveyed containers toward the container bottoms so as to be reflected downwardly at both outer and inner surfaces (28, 30) of the container bottom. The downwardly reflected laser beams are detected by a detector (32) so as to measure the thickness of each container bottom along a predetermined path. The inspected blow molded containers (10) are conveyed upright and the inspection path is along a bottom (34) of the container while the containers are conveyed by a rotary wheel (40) that is driven at a constant speed.

Un método y un aparato (16) para examinar el grueso de envases moldeados soplo transportados que (18) utiliza una fuente de laser (22) para dirigir un rayo laser (24) ascendente del exterior de los envases transportados hacia el envase basa para para ser reflejado hacia abajo en las superficies externas e internas (28, 30) del fondo del envase. Los rayos laser hacia abajo reflejados son detectados por un detector (32) para medir el grueso de cada fondo del envase a lo largo de una trayectoria predeterminada. Los envases moldeados soplo examinados (10) son montante transportado y la trayectoria de la inspección está a lo largo de un (34) inferior del envase mientras que los envases son transportados por una rueda rotatoria (40) que se conduzca a una velocidad constante.
