Fully Automatic Operation
The B & H GES 2.0 is designed to automate the adhesive application process by eliminating mechanical components that require manual set-up processes, constant adjustment and routine maintenance.
How is fully automatic operation possible?
Let’s start with set-up tasks.
Traditional glue wheel systems employ a high rpm rotating glue wheel that is open to the environment. This rotating glue wheel requires other mechanical components to control the flow and application of glue to labels. Each and every mechanical component must be must be set-up correctly for the system to function. With the GES, there is no glue bar, no glue roller, no guitar strings, no doctor blade and no glue pan. By eliminating these components, and replacing them with a PLC controlled and recipe driven system, all traditional glue wheel set-up tasks simply go away.
Manual set-up is replaced a fixed position pattern nozzle and preprogrammed recipes and system parameters that automatically execute all GES set-up requirements. When a recipe is selected, the system sets itself to the correct labeling position, and the GES program controls the application of glue to labels. This includes the adhesive laydown weight, the dimensions of adhesives patterns and the position of the adhesive patterns on the label.
The time consuming manual set-up required by traditional glue wheels, glue bars, doctor blades and glue wires are eliminated by the closed GES design.
Now let’s talk about hands-off operation during production.
Eliminating the mechanical glue wheel system components mentioned above eliminates all the manual operator adjustments associated with these mechanical components.
Replacing the open design of the glue wheel system with the closed design of the GES eliminates other issues that create the need for manual operator adjustments.
The open, mechanical design of the glue wheel system exposes melted glue to the labeling environment and then recirculates and reheats the melted glue repeatedly throughout the labeling process. During this process adhesive temperatures fluctuate on the glue wheel system because hot glue is deposited on a rotating glue wheel that is exposed to the atmosphere where the glue cools, and unused glue is scraped off into a glue pan that is also exposed to the atmosphere. Fluctuating glue temperatures contribute to glue pan overflows, glue stringing, and glue slinging which require operator adjustments.
All the excess glue scraped from the glue roller by the doctor blade, along with glue char, label debris and other contaminates are then recirculated through the glue tank which completes the reheating cycle. Recycled, burnt and contaminated glue can then inhibit the glue application process, which in turn requires adjustments by the operator.
The closed GES only exposes glue to the environment at the point of application. This eliminates opportunities for contamination. The GES also maintains glue temperature plus or minus 1 degree F, and glue recirculation is reduced by over 90%.
