Marathon SL

Introduction

MODULAR PLATFORM

The Marathon SL utilizes the in-line, roll-fed labeling concept invented by B & H, and B & H's patented Constant Velocity Starwheel System, to apply wrap-around labels to cylindrical containers at speeds up to 350 containers per minute (CPM). Modular in design, the SL offers a range of options and operating speeds to fit a wide range of applications in the food, beverage, and household product markets. A base model Marathon SL can also be upgraded in place to increase its operation speed or to add available options like a second roll stand that can increase productivity.

SMARTdrive® FOR HIGH PRODUCTIVITY AND LOW TOTAL COST OF OWNERSHIP

Accurate labeling of containers requires precise synchronization of all machine operations.
Marathon is the first labeler to feature SMARTdrive®, a digitally based timing control system using multi-axis, independent servomotors communicating on a high-speed bus. In other labelers, synchronization is achieved by mechanically linking and timing machine components using gears, belts or chains. Marathon's simplified SMARTdrive design also uses significantly fewer mechanical parts and delivers more consistent and accurate label application over the machine life. Other benefits include higher reliability and uptime, and lower total cost of ownership over the life of the labeler.

FAST, 15 MINUTE CHANGEOVERS

Key machine set-up parameters are stored in a "recipe" database and downloaded for each container and label combination. The PLC then automatically sets all key components to their zero position so labeling can begin. This eliminates the need for tedious machine
adjustments after replacing change parts. Marathon sets a new standard for container changeover time - less than 15 minutes from one full production speed to the next.

DESIGNED WITH THE OPERATOR IN MIND

Set-up and control is simplified with an operator HMI that swivels for easy viewing. Its color touchscreen interface offers intuitive features such as drop-down menus, graphics, and navigation bars.

Highlights

• Everyday production speeds up to 350 containers per minute
• Available in straight through conveyorconfiguration
• Siemens controls and drive train components standard
• 15 minute production speed to production speed size changeovers
• Patented constant velocity starwheel system delivers smooth, efficient container handling
• Advanced Registration Control system is standard
• Marathon SL PLC can be programmed to execute upstream and downstream line control functions to maximize productivity
• Lower maintenance requirements and lower spare parts consumption versus mechanical or rotary labelers
• Superior Total Financial Impact (TFI) versus other labelers based on higher productivity and lower total cost of ownership
• B & H's TFI model and process can calculate and compare the total financial impact of Marathon versus any competitive technology

Principles of Operation

Labels are supplied in the form of a continuous web, cut in precise registration with a printed graphic, and then a hot melt adhesive is applied to the label using a rotating glue wheel. Containers enter the machine via an infeed conveyer and are precisely metered and separated using a starwheel with pockets. The starwheel delivers the container to a rotating vacuum drum that is carrying the glued label. Precision label application is achieved by rolling the container across the label-bearing surface of the vacuum drum. The labeled container is then discharged from the vacuum drum and exits the machine via a discharge conveyor.
