摘要： 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.

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.

摘要： Systems and methods measure a thickness of a plastic article in two phases. In an initialization phase, a photosensor separately and sequentially measures incident light energy from a light source for each a plurality of spectral sub-regions within a total measurement range without the plastic article to be measured being present. A processor computes a baseline incident signal level for the initialization phase by summing the incident light energy for each of the plurality of spectral sub-regions within the total measurement range. In a measurement phase, the photosensor detects light energy that is incident on the photosensor after being transmitted by the light source through the plastic article. The processor computes the thickness of the plastic article based on at least (i) light energy detected by the photosensor and (ii) the computed baseline incident signal level.

摘要： Systems and methods for controlling the operation of a blow molder are disclosed. An indication of a crystallinity of at least one container produced by the blow molder may be received along with a material distribution of the at least one container. A model may be executed, where the model relates a plurality of blow molder input parameters to the indication of crystallinity and the material distribution and where a result of the model comprises changes to at least one of the plurality of blow molder input parameters to move the material distribution towards a baseline material distribution and the crystallinity towards a baseline crystallinity. The changes to the at least one of the plurality of blow molder input parameters may be implemented.

摘要： A method and apparatus are provided for inspecting glass containers for checks (56). The container finish is illuminated from the exterior and light reflected from a check is detected by the apparatus. In one embodiment, the glass container (4) finish is inspected for horizontal and related diagonal checks and, in another, the glass finish is inspected for vertical and related diagonal checks. The checks redirect the normal beam of light and thereby permit the reflected light to be delivered to a detector (12) which converts the received light into a corresponding electrical signal which is compared to a standard in order to determine whether the container should be rejected (22). The method eliminates incorrect inspection results due to reflection of light caused by threads, lugs, mold seams, takeout beads and the sealing surface of the container mouth. The vertical and horizontal embodiments may be combined into a single system which inspects for vertical, horizontal and diagonal checks.
