17,000 orders per hour sounds impressive — first ask how many times a day the line stops

Just saw a piece of news: a courier station installed an automated sorting machine, 17,000 parcels per hour, peak throughput up to 400,000 items, parcels running on a conveyor at 2.2 meters per second, high-speed cameras scanning the waybills, the system recognizing the three-segment code, and dropping them into the chutes automatically. The numbers are pretty intimidating.

But that wasn't my first reaction. I work in warehouse robotics myself and have dealt with sorting lines plenty of times. What I fear most is it stopping mid-run; not hitting peak throughput is secondary.

Tiangong's smart logistics sorting solution follows the same approach: cameras capture the waybill, parse the routing, and drive the chutes. Recognition itself isn't hard these days—what's hard is the waybill. The waybills I've seen in real warehouses: wrinkled ones, ones stuck on crooked, ones wrapped in a layer of reflective clear tape, and soft packages bulging and deforming the code. Standard items running 17,000 an hour is no surprise; when these items fall through, you need someone squatting by the chute picking them up.

AI visual sorting is indeed one direction for logistics upgrades—that's true—but the cost of the upgrade usually isn't written on the equipment quote.

Changeovers too. Different customers have different three-segment code rules, the chute layout needs rearranging, parameters need reconfiguring. I'm familiar with this work—I mentioned it before when talking about recipe management: once there are many points, every changeover requires re-teaching, and the cycle gets completely messed up. Same logic for sorting lines, just larger scale and more expensive downtime.

So my judgment is one sentence. When purchasing, don't just ask about peak throughput—ask them how many times a day the line stops, how long each stop lasts, and who handles the exception items. These numbers are what determine how many years it takes to pay back the money.

Equipment is bought to run; good-looking specs are useless.
