20120018925 | INSPECTION SYSTEMS AND METHODS FOR BLOW-MOLDED CONTAINERS - Systems and methods for in-line inspection of plastic blow molded containers. The inspection system may comprise a plurality of emitter assemblies arranged in a vertical array. Each emitter assembly may cyclically emit light energy in at least two different narrow wavelength bands at a container as the container passes through an inspection area. The system may also comprise a plurality of broadband photodetectors arranged in a vertical array, each photodetector facing at least one of the emitter assemblies with the inspection area therebetween such that the photodetectors are capable of sensing light energy that passes through the container when it is in the inspection area. The system may also comprise a processor in communication with the photodetectors for determining a characteristic of the container based on signals from the photodetectors. | 01-26-2012 |

20080197542 | Apparatus and method for manufacturing and inspecting blow-molded plastic containers - A method and apparatus for manufacturing and inspecting plastic containers. The apparatus may comprise a blow-molder comprising a plurality of molds and spindles for forming a plastic container from a preform. The apparatus may also comprise an inspection device, located in the blow-molder, for inspecting the plastic container after formation by the blow-molder. The inspection device may comprise (i) two or more light energy sources for directing light energy from an exterior of the plastic container toward the plastic container after formation of the plastic container by the blow-molder, and (ii) two or more light energy sensors, each light energy sensor operatively associated with one of the light energy sources, wherein each light energy sensor is for sensing a portion of the light energy that passes through of the plastic container and generating a signal from the sensed portion of the light energy that passes through the plastic container that is related to the light energy absorbed by the plastic container. The apparatus may also comprise a transfer arm in the blow molder for transporting the plastic container along the transport path through the inspection device. The apparatus may also comprise a microprocessor in communication with the inspection device for (i) determining a container attribute of the plastic container based on the signals related to the light energy absorbed by the plastic container; and (ii) determining the mold involved in formation of the plastic container based on at least one signal received by the microprocessor. | 08-21-2008 |
