Automation: Filling the gap between narrow aisle and AS/RS

For the last couple of years, AGVs and mobile robots have been getting all the automation love. Who doesn’t get a kick from watching those Kiva vehicles shuttle around the floor at ProMat and Modex. Better yet, there have been exciting new developments around trailer loading and unloading AGVs along with the introduction of automatic lift trucks. While end users are still figuring out how these technologies fit in their operations, they could make significant inroads in automating receiving and shipping docks.

Less noticed have been the innovations around automated storage and retrieval. Look closely at some of the solutions on display at the shows, and you see technologies that fill the gap between narrow-aisle storage and a fully automated mini-load or unit load AS/RS.

One of the first examples I saw was the AutoStore solution from Swisslog at the North American show back in 2009. The technology uses mobile carts that ride atop rails to deliver products to and from a storage unit. You can watch a YouTube Video here.

Earlier this month, I visited two booths at Modex that highlighted two other takes on automated unit load storage. Both were designed to work as semi- or fully-automated solutions and to work in otherwise conventional warehouses rather than high-bay warehouses.

The first was from Power Automation Systems, or PAS. The solution uses vertical lifts and automated carts to store pallets in storage racks. You can watch a YouTube Video here.

The second was automated storage with an Italian flair from Smoov. The system uses radio controlled carts that can move in multiple axis to make the most of pallet storage. As with the PAS system, a pallet can be inducted into the system with a conveyor and vertical lift or by a lift truck dropping it off at the right level. From there, the cart takes over the putaway and retrieval duties. Depending on the layout of the racks, the carts can move forward and backward but also side to side. You can watch a YouTube Video of the solution in action here. 

As with some of the new developments coming out of the AGV market, these solutions aren’t right for every operation. And, as with automated lift trucks, it’s still an open question as to whether end users will embrace them. But with the current focus on labor costs, productivity improvements and incentives to invest in capital equipment, they appear to be worth a second look.
