Riverdale Global's innovative auto‑refill system eliminates downtime for switching drums and prevents uncolored product.

RG Infinity

We have developed a material handling system that automatically refills one or more liquid color drums during the molding or extrusion process.

Our RGInfinity™ auto‑refill system:
  • Eliminates need to replace drums when empty by refilling them from a large central container, or "tote."
  • Serves one machine or can be configured to refill multiple machines running same color.
  • Keeps liquid color sealed off from the workplace through sealed connections from tote to delivery tubes to drums to metering tubes.
Each drum is mounted on a Riverdale Gravimetric Stand (RGS), which monitors the weight of color in the drum and signals a pump valve on the tote when the drum is nearly empty and again when it is full. When the central container needs to be replaced with a full one, the sealed connectors enable a quick changeover.
Containers are available in various shapes and sizes. A typical example is a 200‑gallon rotomolded plastic vessel within a steel supporting framework, but it is possible to use a standard-size drum for refilling the on‑line drum, replacing the empty 'refill' drum with a full one while color metering continues uninterrupted.
Our technology eliminates downtime for switching drums and reduces the occurrence of transitional or off‑specification product with little or no color. Besides preventing downtime, the RGInfinity™ auto‑refill system eliminates the time and labor required for operators to monitor color levels, transport and prepare replacement drums, and wait until on-line drums are finally ready for replacement.

Riverdale Global can offer custom solutions for color metering and multiple machine processes that would otherwise be unavailable.
