A glassware inspection apparatus that includes an electronic control system and method for optimum control of indexing and inspecting glass containers. The control system generally includes a driver circuit for each servo motor of the apparatus, an electronic control unit, and an operator interface. Information about the apparatus and the particular containers being inspected is entered into the control system through the operator interface. The electronic control unit executes a recursive algorithm that utilizes the inputted information, as well as predetermined constraints of the apparatus, to develop an optimum motion profile for each servo motor. The optimum motion profiles provide the overall apparatus with coordinated control and increased container throughput speed, while efficiently distributing cycle time and thermal energy between the various servo motors.

Electronic control system for container indexing and inspection apparatus

An apparatus for inspecting articles of glassware at a plurality of angularly spaced inspection stations includes a conveyor that moves articles of glassware to and from inspection stations, a drive roller that rotates articles of glassware at at least one inspection station, and an inspection device spaced from an inspection station and adapted to inspect an article of glassware as it is moved by the conveyor and caused to pass by the inspection device. A method for inspecting articles of glassware at a plurality of angularly spaced inspection stations includes the steps of moving the articles of glassware to and from the inspection stations, rotating the articles of glassware about an axis at at least one inspection station, inspecting the articles of glassware while they are rotating, stopping the rotation about the axis of the articles of glassware, moving the articles of glassware away from said at least one inspection station without rotating the articles of glassware about said axis, and inspecting the articles of glassware as they are moved.
