摘要： 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.

摘要： A method of inspecting wall thickness of blow-molded plastic containers includes providing a blow-molder having a plurality of molds and a plurality of associated spindles. The containers are inspected by impinging infrared light thereon and detecting the portion of the infrared light that passes through the container and converting the same into corresponding electrical signals which are delivered to a microprocessor. The microprocessor compares the electrical signals with stored information regarding desired wall thickness of the container and emits output thickness information. The microprocessor receives signals from sensors associated with the blow-molder relating to the position of the molds, the identity of the molds and the identity of the spindles in order that the wall thickness information that is determined by inspection can be associated with specific molds and spindles. The wall thickness information may be averaged over a period of time or a number of containers. The information may be visually displayed so as to provide feedback regarding the inspection process. In a preferred embodiment wall thickness measurements are taken at several vertically spaced positions simultaneously. Corresponding apparatus is provided.
