Thermal Ink Jet Printer for Real-Time Egg Carton Coding

The patent replaces mechanical stampers and reciprocating ink printers with a thermal ink jet printer system. This substitution eliminates the need for physical type sets and mechanical indexing mechanisms, enabling variable data printing (dates, batch numbers, codes) without compromising print quality consistency. The thermal ink jet technology provides both the adaptability for variable content and the precision required for consistent print output.

The invention introduces a movable printhead that can dynamically adjust its position along the conveyor path. This dynamic positioning capability allows the printer to accommodate variable carton speeds and positions while maintaining precise print placement. The printhead can move to compensate for speed variations without requiring expensive encoder systems, thus providing both adaptability and manufacturing precision.

The patent employs a movable printhead that can dynamically adjust its position to track the moving carton. This dynamic positioning system allows the printer to maintain accurate print placement even when cartons move at variable speeds, eliminating the need for expensive encoder systems while preserving both productivity and measurement precision.

The invention introduces an intermediary positioning system between the printhead and the moving carton. This intermediary mechanism allows the printhead to independently adjust its position to compensate for carton speed variations, ensuring accurate print placement without requiring direct speed synchronization or expensive encoder feedback systems.

The patent creates a universal printer platform where a single thermal ink jet printer design can be deployed across multiple locations in the egg carton filling line. The standardized design with movable printhead and common control architecture allows multiple printers to be managed through a single control system, increasing productivity while minimizing the complexity increase that would normally accompany multiple devices.

The invention merges multiple printer control functions into a single centralized control system. This allows multiple printers to be coordinated and managed together, reducing the operational complexity that would otherwise result from having separate control systems for each printer. The merged control approach maintains high productivity while simplifying the overall system architecture.
