Abstract
A color monitoring device includes a mechanism for removing containers from a path and accurately positioning a preselected area with a color monitor. The color monitor produces an output signal representative of the area being monitored which is amplified and fed to a computer where it is compared with reference signals. If the output signal is outside prescribed limits, the container is rejected, and if it is within prescribed limits, the container is returned to the path. A shuttle mechanism is activated by the computer and automatically removes a container from the path while returning a previously inspected container to the path. Stepper motors are used to vertically and horizontally position a selected point in front of the colorimeter.
