Abstract:
The invention provides for a graphical user interface which provides for very simple and intuitive ways of changing single or multiple inspection parameters. The graphical display immediately shows what the monitoring or inspection result would have been if the effected change had been in place during the inspection of the last "N" parts. This retrospective graphical "look-back" invokes immediate re-inspection facilitating an estimation of what the future inspection or process monitoring results will be if future production looks similar to the recent past production. The re-inspection results are immediately shown with a combination of visualization for ease of understanding and settings optimization. The visualization also shows selected other associated data to each specific inspection for ease of tracking and optimizing production processes.
Abstract:
A stretch blow molding system that condition preforms such that the temperature distribution within the cross-section of each preform (10) is optimized prior to blow molding operations is provided. The system has a temperature measurement (20) and control system (30) capable of directly monitoring both the outside as well as inside surface temperature of preforms at different stages of transport throughout the thermal conditioning section (100) of the system.
Abstract:
A system for illumination of discrete specimens in an optical inspection system (A) include an image acquisition system (C) and corresponding illumination system (B). A beam splitter (16) intercepts light from a light source (10) and communicates a portion of it to field lens (20). A field lens (20), in turn, communicates light to a specimen (24) disposed in a viewing area (22). Light reflected from the specimen (24) is communicated back through the field lenses (20), through the beam splitter (16) and ultimately to a video camera (34) from which a digitized image is obtained. In another embodiment, light reflected from the specimen (24) and propagated through the beam splitter (16) has communicated to a second beam splitter (30). Separated light therefrom is communicated to first and second video cameras (34, 36), thus allowing for imaging of separate portions of the specimen (24).
Abstract:
A parcel detection system (A) works in connection with a stream of parcels (B), such as might be encountered in connection with bulk mail sorting apparatus. A presence of multiple parcels traveling adjacent one another is detected with a line scan charge coupled device (34). A transducer array is disposed perpendicularly to the stream flow. Specular illumination of edges of the parcels is completed to facilitate capturing an image in the CCD array (34). An analog signal, obtained from the array, includes information representative of a number of adjacent parcels. This information is processed to provide a signal representative of a number of parcels traveling adjacent to one another in the stream.
Abstract:
A system for direct injection of selected thermal-infrared (IR) wavelength radiation or energy into food items for a wide range of processing purposes is provided. These purposes may include heating, raising or maintaining the temperature of the food articles. The system is especially applicable to operations that require or benefit from the ability to irradiate at specifically selected wavelengths or to pulse or inject the radiation. The system is particularly advantageous when functioning at higher speeds and in a non-contact environment with the target.
Abstract:
An engineered video inspection system for high speed video inspection includes an array of light emitting diodes including light emitting diodes for use in time delay integration (TDI) inspection of web materials. The light emitting diodes of the array are selectively controllable to accomplish sequential illumination and carefully controllable imaging of a specified section of a continuously moving specimen or specimens. LEDs with different wavelength light output, or multi-wavelength light LEDs are utilized of rapid and reliable inspection of surfaces with varying color or contour or detect characteristics. The system also includes an array of optional backlighting elements to aid in illumination of semi-opaque specimens to accomplish inspection thereof.

Abstract:
This invention relates to an apparatus and method for inspecting multi-layer plastic containers (10). More particularly, the invention relates to such an apparatus and method whereby optical energy absorbing compounds are added to the materials comprising the layer(s) of the container (10) to facilitate inspection thereof. Apparatus comprises a sensor unit (40), an illumination unit (30) for illuminating a portion of electromagnetic spectrum at a near IR wavelength to an inspection zone (20) which is located between the sensor unit (40) and the illumination unit (30). A processing unit (50) which receives an output of the sensor unit (40) and determines the attributes of the multi-layer plastic containers (10).
Abstract:
This invention relates to a method and apparatus for handling parts ejected from an injection molding machine (10). More particularly, in one aspect, the invention is directed to a system (20) whereby data molded into the ejected part is used to provide useful feedback for the molding process. In another aspect, molded parts formed in a multiple molding die (12) are ejected from the die in a manner to maintain the relative sequential or matrix organization so that useful feedback information can be generated. This system is particularly useful with subsequent machine vision and inspection applications.
Abstract:
A system for automated inspection of article exteriors includes a plurality of video cameras (32). One or more of these video cameras (32) is black and white while at least one is color capable. A strobe light for illuminating a specimen (22) disposed in a specimen area (24) onto which all of the cameras (32) are focused. The strobe allows for each camera (32) to capture a still image of the specimen (22), The black and white cameras (32) capture images which allow determining whether the exterior layout is acceptable. The color camera or cameras (30) captures an image which allows determining whether the coloration of the specimen (22) is acceptable. Specimens (22) are selectively rejected on the basis of these acquired images. The system is particularly useful in inspection of beverage container (22) and their associated labelling.
