Central Palletizing: A Smarter Layout for Multi-Line Facilities

Most manufacturers think about palletizing the same way: one line, one robot, one pallet station at the end of that line. That model works, but it is not always the most efficient use of floor space, equipment, or labor. Central palletizing offers a different approach, and in 2026 it is becoming one of the smarter investments available to mid-sized facilities running multiple production lines.

What Central Palletizing Actually Means

Central palletizing combines two or more production lines by automating the transport of all products to one convenient location for robotic palletizing. Instead of a dedicated palletizer at the end of each line, products are conveyed or transported via AGV to a shared palletizing cell where one or more robots handle the full throughput of the facility.

This creates greater efficiency for the overall transport of product and needs fewer employees to manage end-of-line operations. Rather than staffing and maintaining three separate palletizing stations for three production lines, a facility can run all three through a single automated cell with centralized controls, centralized maintenance, and a smaller combined footprint.

Why Facilities Are Moving to Centralized Palletizing

The palletizing automation market in the US was valued at $874.5 million in 2025 and is projected to reach $1.36 billion by 2035. Robotic palletizers now account for nearly 60% to 64% of new installations, and automation improves operational efficiency by 30% to 38% while reducing manual handling errors by 20% to 25%. Central palletizing captures a larger share of those gains than line-dedicated systems because the economics compound across multiple lines.

The key advantages are straightforward. Fewer robots means fewer capital expenditures, fewer spare parts inventories, and fewer technicians needed for maintenance. A single palletizing cell is easier to monitor and troubleshoot than three separate ones. And because the cell is designed around the combined throughput of multiple lines, it can be sized to handle peak demand more effectively than individual line-end units that are each sized conservatively.

Centralized solutions are also scalable. Schneider's centralized palletizer approach, for example, is specifically designed to offer combined benefits including overall warehouse traffic reduction, better utilization of valuable space, increased uptime with reduced complexity, and the ability to meet changing demands as the business grows. That last point matters: a central cell can absorb a new production line by adding conveyor routing, while adding a new line-end palletizer means buying and commissioning an entirely new system.

How the System Is Laid Out

A central palletizing system typically consists of inbound conveyor lines from each production area, a staging and sequencing zone that manages product flow from multiple sources, one or more robotic palletizing cells, and outbound pallet handling including stretch wrapping and transport to storage or shipping.

Staging conveyors and sequencing logic manage product flow from the various inbound lines. Software algorithms calculate the best stacking patterns based on case dimensions, weight distribution, and pallet stability requirements. The robot handles products individually, by row, or by full layer depending on throughput requirements and product type. When a pallet is complete, it is conveyed directly to stretch wrapping, enabling continuous flow from the production floor to ready-to-ship pallets with minimal human involvement.

AGVs are increasingly used in place of fixed conveyors for the transport leg, particularly in facilities where production layouts change frequently. The CODI and Festo FlexStack Pro gantry palletizer, shown at MODEX 2026, was designed specifically for facilities where cobots are too slow or too limited in payload but a full industrial palletizer is more than the application requires. Gantry systems require less floor space than articulated arm setups because the handling system is directly above the work envelope, which makes them well-suited for tight central palletizing areas.

When Central Palletizing Makes Sense

Central palletizing is not the right answer for every facility. It makes the most sense when two or more production lines produce at moderate, manageable rates that a single robot or cell can absorb, when floor space near individual line ends is constrained, when reducing the total number of automation systems and maintenance contracts is a priority, and when the facility has a clear path to the central location for conveyor routing or AGV travel.

It is less well-suited to facilities where individual lines run at very high speeds that would overwhelm a shared cell, or where products from different lines are incompatible in terms of handling requirements. In those cases, line-dedicated palletizing remains the better answer.

At CES 2026, Universal Robots and Robotiq unveiled a next-generation palletizing solution in collaboration with Siemens, combining the UR20 cobot arm with Robotiq's PAL Ready palletizing cell and Siemens' Digital Twin Composer software. The digital twin capability is particularly relevant to central palletizing projects because it allows facilities to simulate the full cell, validate cycle times and layout, and confirm throughput before committing to infrastructure changes.

The Robot Arm at the Center

The robot arm is the core of any central palletizing cell. Articulated robots are projected to account for 39.2% of the robotic palletizers market in 2026, and for good reason: a six-axis arm can reach across a wide work envelope, serve pallet positions on multiple sides of the cell, and be reprogrammed for new product SKUs or pallet patterns without mechanical retooling. With a reach of 3.15 meters, arms like the ABB IRB 660 can stack high pallets and serve multiple lines from a single location at up to 2,190 cycles per hour.

For facilities where throughput is moderate and worker proximity is a factor, collaborative robot arms offer a compelling option. Cobot palletizers work without a fence or safety cage, dramatically reducing the cell footprint and allowing operators to work alongside the system. FlexLink's RC12 collaborative palletizer, for instance, reduces footprint by over 50% compared to industrial robot cells while handling up to 14 boxes per minute with double pick.

Conclusion

Central palletizing is not a separate category of automation from robotic palletizing. It is a smarter layout strategy that applies the same robotic technology more efficiently across multiple production lines. For facilities with two or more lines and the floor space to route product to a shared cell, it typically delivers better ROI, lower maintenance overhead, and a more scalable foundation than duplicating line-end equipment across the facility.
