Case Coding on Box Conveyor Packaging Lines

Conveyors, especially roller conveyors, can create vertical movement and vibration, causing the leading and trailing edges of a box to be at different levels. This misalignment can impact nozzle accuracy, resulting in head collisions, splashback, or clogging. Bump-turn systems attempt to correct orientation but require additional space and introduce points of failure. Inconsistent line speeds and mistimed sensors also lead to poor placement and distorted prints. On busy lines, that can mean unreadable barcodes, failed scans, and manual recoding.

The MSU, integrated into the KEYENCE CC-1000 Series, eliminates the challenges caused by uneven box levels, vertical movement, and vibration, ensuring consistent print alignment. The nozzle stays aligned even if the conveyor doesn’t. If conditions change beyond safe thresholds, the system alerts operators before problems occur. Paired with the built-in inspection camera, each print is instantly verified for position and content. This type of MSU conveyor stability ensures consistent print alignment on conveyors without requiring additional hardware.

MSU-enabled case coders handle a wide range of industrial packaging conveyor printing setups, including shipping cases, retail cartons, flat-packed trays, and pouches. Lines that run varying product sizes or operate at variable speeds benefit most as the MSU adjusts without slowing production. Whether used in food, pharma, or general packaging, the MSU ensures stability across varying workflows.
