Glass container inspecting machine

摘要

The thickness of a formed glass container is evaluated around its wall periphery by making a selected sampling of voltage data. An encoder is used which displaces the periphery past a sensor and sampling is synchronized with the pulses of the encoder. When a seam is detected, sampled data is ignored for a chosen number of pulses prior to as well as following and the number of pulses is set by defining the diameter of the container.
