Abstract
A glass container inspection machine including a bottle handling mechanism which presents glass containers to a capacitive sensor which provides a voltage signal representative of the thickness of the glass container, a computer which receives the voltage signals, a keyboard for inputting data into the computer, and a display. The thickness of a glass container is measured at four points, and as each point is presented to the sensor, the measured thickness in input into the computer, which stores the sensed voltages, correlates them to the input thicknesses, and calculates a curve used to determine glass thickness from sensed voltage. Alternatively, the minimum and maximum thicknesses of a glass container are measured, input into the computer, the container is passed through the machine, and the computer correlates the lowest and highest voltages sensed with the minimum and maximum thicknesses respectively, and uses this data to generate the calibration curve. The measured data is input by aligning a cursor with a data category on the display screen and entering the data via the keyboard. The computer senses the voltage(s) on the next bottle presented to the sensor and displays them on the screen in the selected data category.
