Carton flow, also known as flow racking, roller racking, and gravity flow racking, is a dynamic storage solution that can dramatically improve space utilization and order picking efficiency within warehouses, order fulfillment centers, retail stores, and manufacturing facilities. Carton flow tracks are conveyors - either roller or wheel-based - that are cut to a size that will span the length of a bay of pallet racking. Carton flow tracks create storage lanes within pallet racking designed to increase material flow, enhance space utilization, and improve efficiency throughout a facility. Carton flow uses gravity to flow products through the rack, allowing for streamlined replenishment, storage, and order or part picking.
There are many different capacities and styles of carton flow, making it a very dynamic storage system that can meet the needs of operations across industries. That said, with the ability to create tailor-made solutions comes a set of important decisions like, what capacity do I need? Do I need carton flow rollers or wheel beds? What roller centers will work best? What are roller centers?! Well, lucky for you, you’ve come to the right place. As the makers of The Original Carton Flow Track, SpanTrack, our team of experts at UNEX are uniquely qualified to answer all the nitty gritty questions you have about carton flow. In this article, we will answer the question, “What are carton flow roller centers?” and provide some deeper details that will help you choose the right roller centers for your carton flow applications.
When someone mentions carton flow “roller centers,” they are referring to the spacing between each roller in a carton flow track. As products or cartons increase in length, additional space can be added between rollers to optimize flow. Other factors like humidity, condition of boxes, bottom surfaces of totes, the weight of your boxes, and more can influence your decision in choosing the correct roller centers for your carton flow tracks.
Selecting the correct roller centers may seem like a small detail, but it is not to be overlooked! Roller centers can impact how fast or slow objects roll along the tracks. Items that flow too fast can cause damage, whereas items that flow too slow - or not at all - well, they may not even reach the point of pick! The pitch of your tracks also plays a huge role in creating optimal flow, but it is pitch and roller centers that really allow you to fine-tune your carton flow tracks to work with the utmost precision.
Having closer roller centers will increase the conveying surface and make the system more flexible. Analyzing your inventory and throughput will allow you to identify the dimensions of your SKUs that need to be placed in carton flow and help you make the best choice for roller centers.
