This case study is compliments of Aloi Materials Handling and Automation. Aloi, one of Alba’s System Integrators, established in 1977, has six locations including their Corporate Headquarters in Rochester, New York.

The end user is a worldwide distributor of refrigerants for automotive, residential, commercial, industrial air conditioning, and cold storage refrigeration applications. They package and distribute pure refrigerants.


In this application, the end user was bringing a new plant expansion online and needed to robotically palletize cases of refrigerant for distribution.


Operation Sequence

The system begins with dispensing 40″ x 48″ GMA pallets one at a time from an Alba Pallet Dispenser. The pallets are picked up robotically and placed on one of four palletizing lanes of Alba CDLR Conveyor. Individual cases are brought to the robot on case conveyor (by others).

Once the product is palletized, the 2,000-lb., fully loaded pallets of refrigerant are conveyed to the end of the lane where a series of Thru-Frame and Thru-Drive Side (through the chain box) style transfers convey pallets across the line over to the end of the last lane. The pallets are then stretch wrapped. Wrapped pallets are then picked up by fork trucks for delivery to the shipping or loading docks.

Increased efficiency for the customer and, more important, increased worker safety.
