Semi-automatic equipment is also a possibility with GTD. This machine bowl-feeds a plastic holder into an in-line walking beam mechanism. As these parts are indexed down the line an operator manually loads another metal part into each one. The two parts are pressed together automatically, inspected by a vision system, and good parts are loaded into shipping tubes, 50 to a tube. Filled tubes are automatically shuttled out to an accumulation table where the operator "caps" the tubes and boxes them.
This machine takes parts manually loaded by the operator and assembles them. A bar code scanner reads the bar code and sets the machine parameters. Indicator lights offer feedback to the operator at each step of the loading process. Once the correct parts are loaded, the parts are pressed together automatically. We have modified this machine to add additional assemblies two years after first going into production.
