Routing Without Risk: Why Divert & Merge Systems Matter More Than Ever in 2026
As South Africa’s online retail and logistics sectors grow, warehouses are handling more SKUs, more channels, and more delivery destinations than ever before.
The challenge is no longer just moving boxes. It’s about getting every carton to the right lane, at the right time, with minimum manual touch.
That’s where divert and merge systems come in.
The new complexity in SA distribution centres
A few realities are shaping South African operations:
- Online retail is now a major share of total retail, with forecasts that it will reach roughly 10% of all retail turnover in 2025.
- More players and platforms (Takealot, Amazon, Shein, Temu and others) are increasing parcel flows and delivery promise pressure.
- Logistics automation investment is rising, with SA’s logistics automation market expected to grow at around 9–13% CAGR this decade.
The result:
Single-line conveyor systems and manual sorting points quickly become bottlenecks.
Divert and merge systems give you fine-grained control over where product goes next.
What are divert & merge conveyor systems?
- A divert system automatically steers cartons or parcels off a main conveyor and into different lanes or zones (e.g. sortation lanes, carrier lines, or staging areas).
- A merge system combines product from two or more lines into a single, controlled flow.
According to leading conveyor manufacturers and integrators, divert systems:
- Increase throughput
- Reduce sorting errors
- Automate the directing of products to the correct destination
- Minimise congestion and downtime in the conveyor system
In plain language: they help make sure the right parcel goes to the right place at the right speed.
Why they matter more than ever in 2026
1. Mixed parcel sizes and multiple destinations
South African DCs and hubs are no longer dealing with uniform cases on pallets.
You’re probably handling:
- Different carton sizes and weights
- B2B and B2C flows in the same facility
- Multiple carriers and line-haul routes
- Store replenishment and home delivery next to each other
Divert and merge systems allow you to:
- Separate flows by destination, carrier, route, or priority
- Manage mixed product on the same belt without chaos
- Keep main lines moving while routing efficiently into branches
2. Reducing manual decision points
Every time a person has to:
- Read a label
- Decide where a carton should go
- Push, pull, or redirect a box
…you slow down flow and introduce error risk.
Automated diverts use barcode scanning or vision data to route cartons automatically. That:
- Reduces manual handling
- Lowers the risk of “wrong lane” errors
- Helps you maintain performance when labour is tight
3. Protecting throughput in peak
Peak season (Black Friday, festive, back-to-school) can easily double or triple daily volume in large SA operations. Without proper routing infrastructure, main conveyor lines get congested and stop-start.
Divert and merge systems help by:
- Dynamically balancing flow between lanes
- Feeding sorters or accumulation lanes at controlled rates
- Allowing surge volumes to be buffered in the right areas
This gives you more stable throughput, even when demand spikes.
4. Enabling phased automation
Many South African operators can’t switch to full automation in one step.
Divert and merge systems are a perfect phased upgrade because they:
- Plug into existing conveyor infrastructure
- Can be added at choke points where congestion is worst
- Prepare the system for future sorters or automated storage
Think of them as the “mid-brain” of your conveyor network.
Key questions to ask before investing in divert & merge systems
If you’re planning for 2026, consider:
- Where do queues or backlogs form now?
- Which destinations or carriers cause the most manual sorting work?
- Do you have clear data on volumes by lane or route?
- Can your existing conveyor speeds and widths support higher throughput?
- How will diverts integrate with scanners, WMS, and controls?
The answers will shape how many diverts you need, where to place them, and how to configure routing logic.
