At Pack Expo, B and H Labeling Systems will introduce the next generation of Marathon roll-fed labellers.

This latest generation of Marathon SLA, XLA and XLUA labellers includes over two dozen new design features that are said to enhance Marathon’s ease of operation and speed of changeovers.

The latest generation of Marathon labellers includes new design features that impact every key functional component of the machine, from container infeed to container discharge.

Machine components including the label unwind system, the roll-on belt system, the feedscrew assembly and the feed roller/pressure roller system all include new design features and upgrades.

Popular options including extended infeed and discharge conveyor, and one-touch hand valves for the label unwind core chucks have also been added as standard features.

B and H offers three models of Marathon labellers, all designed for ease of use, low maintenance and high operating efficiencies with fast size changeovers and high reliability.

The Marathon series of labellers can label containers from 8oz to 3 litres in size.

Ideal for low- to mid-speed operations, the Marathon SLA labels up to 450 containers per minute (cpm).

The Marathon XLA achieves speeds up to 650cpm.

The high-speed Marathon XLUA features a 180deg U-shaped conveyor that maximises container stability at speeds up to 650cpm.

Featuring B and H’s Smartdrive, a four- or five-axis servomotor drive-train with automatic label registration and timing, Marathon achieves extreme positional accuracy over the life of the machine.

With up to five independent servomotors communicating on a high-speed digital bus to synchronise labelling operations, Smartdrive eliminates the gears, belts and chains found in traditional labellers.

The complete Allen-Bradley drive-train and controls platform consists of Allen-Bradley servo drives, servomotors, programmable logic controller (PLC) and human machine interface (HMI).

With its advanced digital design and recipe-driven repeatability, Marathon labellers achieve a changeover time of less than 15min from one full production speed to another, including the replacement of change parts, by eliminating time-consuming manual adjustments.

Production parameters for every container and label combination can be stored as recipes in the PLC and downloaded to set all servo axes to the appropriate positions.

Lightweight, colour-coded RCO (Rapid Changeover) change parts further ease changeover.
