Marathon SLA

Introduction

SPEED AND FLEXIBILITY FOR MULTIPLE APPLICATIONS

The Marathon SLA utilizes the in-line roll-fed labeling concept invented by B & H to apply wrap-around labels to cylindrical containers at speeds up to 450 containers per minute. Container handling is performed by B & H's patented Constant Velocity Starwheel System that accomodates both flattop and air conveyor systems. The SLA also offers a variety of available options to help it run a wide range of applications in the food, beverage, and household product markets.

HIGH PRODUCTIVITY AND LOW TOTAL COST OF OWNERSHIP

Accurate labeling of containers requires precise synchronization of key 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 to achieve accurate, repeatable synchronization. In other labelers, synchronization is achieved by mechanically linking and timing key components using gears, belts or chains. As these components wear, synchronization becomes harder to achieve and maintain.

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, graphs, and navigation bars.

• Invation passive starwheel with secondary roll-on belt system can increase speeds up to 450 containers per minute
• Intelligent Registration Control system is standard
• Marathon SLA 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

Principles of Operation

Roll-fed labels are supplied from a roll in the form of a continuous web, fed in precise registration with a printed graphic, cut in precise registration, transferred to a rotating vacuum drum, and then a hot melt adhesive is applied to the label using a rotating glue wheel. Cut labels with adhesive are then applied to individual containers which are rotated to complete the label application process. During this process, containers enter the labeler via an infeed conveyor, and are then metered and separated by a rotating feed screw and pocketed starwheel or by a rotating constant velocity starwheel. The starwheel delivers containers to a rotating vacuum drum that transports the label from the cutter, to the glue wheel, and then onto the container as described above. Precise label application is achieved by rolling the container across the label-bearing surface of the vacuum drum. The labeled container then ends contact with the vacuum drum, and it exits the labeler via a discharge conveyor.
