Cobot Palletizer vs Conventional Palletizer

Key differences

Cobot palletizers handle 5–12 cycles/min; conventional palletizers: 12–40+ cycles/min
Cobot palletizer installed cost: $50,000–$120,000; conventional: $100,000–$400,000+
Cobot palletizers use 3–5 m² of floor space; conventional systems require 10–30+ m²
Pallet pattern changes on a cobot palletizer take minutes (software); on a conventional system, hours to days
For throughput above 15 cycles/min continuous, a conventional palletizer is usually the better fit

Cobot palletizer: how it works

A cobot palletizer typically uses a 20–35 kg payload collaborative robot arm (Universal Robots UR20, FANUC CRX-25iA, or Doosan H2515) mounted on a pedestal beside the infeed conveyor. Cases arrive from upstream on a conveyor; the cobot picks each case and places it on a pallet according to a programmed pattern. A pallet dispenser feeds empty pallets; a pallet conveyor or forklift removes full pallets.

Programming pallet patterns: Modern cobot palletizing software (Robotiq's Palletizing Solution, Vention's palletizing module, and others) provides a graphical interface where the operator defines the pallet dimensions, case dimensions, and pattern type (column, brick, pinwheel). The software calculates all pick-and-place positions automatically. Changeover to a new SKU or pattern typically takes 5–15 minutes.

Gripper for palletizing: Vacuum grippers (single or multi-cup) are standard for cartons and cases with flat top surfaces. For bags, a clamp-style gripper or bag-specific suction system is used. Vacuum grippers for palletizing typically use 2–4 large (Ø100–150 mm) cups and a venturi vacuum generator. See the vacuum gripper guide for sizing.

Throughput reality check: A cobot picking a 15 kg case with a standard 1.4 m reach travels approximately 2–3 seconds per pick. Including gripper actuation and conveyor synchronisation, 6–8 cycles/minute is a realistic production rate. The marketed "12 cycles/min" is achievable only with small, light cases, short travel, and optimised path programming.

Conventional palletizer types

Conventional palletizers are dedicated industrial robot or conveyor-based systems engineered for high throughput on fixed line configurations:

Layer palletizer: Cases are arranged into a complete layer by infeed conveyors and then pushed onto the pallet as a unit. Very high throughput (20–60 layers/hour) but requires consistent case size and significant floor space and ceiling height.
Robotic palletizer (industrial arm): A large articulated robot (FANUC M-410, Yaskawa MPL series, ABB IRB 760) with purpose-built palletizing EOAT. Throughput: 15–30 cases/minute. More flexible than layer palletizers; lower footprint. Requires safety cage.
Mixed-case robotic palletizer: Vision-guided robotic palletizer for multiple case sizes. Highest integration cost ($250,000–$500,000+) but handles complex mixed-SKU loads automatically. Used in distribution centres rather than production lines.

The cobot palletizer cost advantage is real, particularly for small manufacturers who do not need 15+ cycles/minute. The conventional system pays for itself through higher throughput on high-volume, dedicated lines.

Decision framework

Choose a cobot palletizer if:

Throughput requirement is under 12 cycles/min
You run 3+ SKUs or frequently change pallet patterns
Floor space is limited (<6 m² available)
Capital budget is under $120,000
Line layout may change in the next 2–3 years
You want operators to manage changeovers without programmer support

Choose a conventional palletizer if:

Throughput exceeds 15 cycles/min consistently
You run one or two SKUs with rare changeovers
Cases are heavy (>30 kg)
The line is fully dedicated with no layout change expected
You need 24/7 uptime with minimal maintenance

Frequently asked questions

What payload cobot do I need for palletizing?

The cobot payload must exceed the case weight plus gripper weight at full extension. For 20 kg cases with a 3 kg vacuum gripper, you need at least 23 kg rated payload — the Universal Robots UR20 (20 kg, but check at full extension) or FANUC CRX-25iA (25 kg) or Doosan H2515 (25 kg) are appropriate. Always check the payload-reach curve, not just the rated payload at the wrist — payload capacity drops with reach distance. Run the robot manufacturer's payload calculator with your EOAT weight and centre-of-gravity offset.

Can a cobot palletizer run unattended overnight?

Yes, with appropriate staging. The key constraint is pallet supply and full-pallet removal: the cobot cannot move a full pallet away — it needs a pallet conveyor, AGV, or forklift to remove it. For overnight unattended operation, use a multi-pallet output conveyor (automatic full-pallet indexing) and a pallet dispenser with capacity for the expected run. Also ensure adequate infeed conveyor buffering and that the EOAT is designed for the cycle count without service interventions. Most cobot palletizer integrators can configure this — it adds $20,000–$40,000 to the system cost.

What is the difference between a cobot palletizer and a traditional robot palletizer?

A cobot palletizer uses a collaborative robot (force-limited, slower) which can operate with simplified guarding (area scanners rather than full cage) and allows operators to access the cell for pallet changes. A traditional robot palletizer uses a high-speed industrial robot that requires full safety caging and stops when the cage is opened. Practical differences: cobot allows manual intervention without cell shutdown; traditional robot is 2–3× faster and handles heavier cases; cobot costs less and installs faster. For most SME applications under 12 cycles/min, the cobot version is preferred.
