Inspection systems and methods for their use comprise: a movable carrier with spaced receptacles, each sized to accept a sample; a first pin positioned proximate to the movable carrier and connected to a first movable member capable of reciprocally moving the first pin alternately into and out of contact with a first end of a sample disposed in one of the spaced receptacles; a second pin positioned proximate to the movable carrier and connected to a second movable member capable of reciprocally moving the second pin alternately into and out of contact with a second end of the sample disposed in the one of the spaced receptacles; a measurement sensor capable of determining a value associated with the sample disposed in the one of the spaced receptacles; and an evaluation device in communication with the measurement sensor for receiving the value, the evaluation device providing a comparison between the value and a predetermined value.

Inspection systems and methods for multi-segment products

A method and apparatus for automatically inspecting transparent or translucent materials, especially plastic materials, the apparatus including a light container, at least one camera, a digital processor, and a reject mechanism, the method comprising conveying a particle of the material through the light container, capturing an image of the particle with the camera, identifying defects in the image with the digital processor, and separating out defective material by communication between the digital processor and the reject mechanism. The light container is an illumination device, preferably an integrating sphere, that has two opposing openings through which a particle can pass and one or more other openings or windows through which one or more cameras view the particle.

System, apparatus, and method for detecting defects in particles

A station optically inspects banded cigarette paper by directing an elongated beam of white light laterally across a web of the cigarette paper. The elongated beam impinges on the surface of the cigarette paper and forms reflections. A plurality of line scan camera containing linear CCD arrays receive the reflections and generate output signals. One or more processing units process the output signals to generate data indicative of the spacing between bands, the width of the bands, and the contrast of the bands. These calculations can be periodically transferred to a separate computer workstation over a network. The workstation generates statistical reports on the basis of the calculations, such as the band width, band spacing and band contrast as a function of lane number, and as a function of time. The statistical reports provide a convenient way of quickly detecting irregularities in application of the bands. According to exemplary embodiments, the inspection station is designed for installation in a cigarette paper manufacturing system.

Optical inspection system for the manufacture of banded cigarette paper

A rewinder machine optically inspects banded paper unwound from a first bobbin by directing an elongated beam of light laterally across the paper. The elongated beam impinges the surface of the paper and forms reflections. A line scan camera containing a linear CCD array receives the reflections and generates output signals. A line scan processor processes the output signals to generate data indicative of the spacing between bands, the width of the bands, and the contrast of the bands. These calculations may be periodically transferred to a separate computer workstation over a network. The workstation generates statistical reports on the basis of the calculations, such as the band width, band spacing and band contrast as a function of lane number, and as a function of time. After being inspected by the camera, the paper is rewound on a rewind bobbin. Various mechanical features of the rewind machine allow rapid mounting and removal of bobbins of paper, and provide for high speed operation.
