Palletizing Robot Selection Guide: Payload, Speed and Layout Configuration for 2026
Selecting the right palletizing robot comes down to four factors: total payload (robot arm plus EOAT plus product), required cycle rate in cases or bags per minute, available floor or overhead space, and whether you need a fixed industrial cell or a flexible cobot deployment. Match those four variables to a verified model spec and your configuration decision is largely made. This guide maps each variable to specific EVST QJAR and XR series options so you can move from requirement to quotation without detours.

Key Specifications That Actually Drive Palletizing Robot Selection
Payload: Including EOAT
The rated payload of a palletizing robot is the load the arm carries at the wrist flange. In practice, subtract your end-of-arm tooling (EOAT) weight from that figure to get actual product-handling capacity. A vacuum gripper with integral slip-sheet handler and product guide rails typically weighs 12–25 kg on its own. If you specify a robot rated at 130 kg and your EOAT weighs 20 kg, effective product payload is 110 kg, enough for a full layer of 25 kg bags but not a full stretch-wrapped pallet tier in a single pick.
Add a 15–20% margin above peak calculated load to protect joint bearings and gearboxes during acceleration at maximum reach. Underrating the payload is the single most common cause of premature gearbox failure in palletizing cells.
Reach
Standard end-of-line palletizing requires the robot to reach from a fixed conveyor pickup point to the far corner of a 1,200 × 1,000 mm or 1,200 × 800 mm pallet, typically at heights up to 1,800–2,200 mm. A minimum working radius of 2,400 mm covers single-pallet applications. Dual-pallet or high-bay tier stacking (above 2,400 mm) benefits from a pedestal mount or a linear robot track that extends envelope without requiring a longer-arm model.
Cycle Rate: Cases per Minute
Cycle rate is calculated as picks per minute (PPM) at rated payload through a full pick-and-place arc. Most FMCG end-of-line lines run 8–14 cases per minute; beverage and pet-food lines can demand 18–22 CPM. When we commission palletizing cells, we calculate worst-case cycle time using actual arc geometry (not the robot’s maximum TCP speed), because joint limits and deceleration phases at layer height change the real-world number significantly. Always request a simulation-validated cycle count, not a theoretical peak.
Repeatability
Palletizing does not demand the ±0.02 mm repeatability of precision assembly. A repeatability of ±0.5 mm is more than adequate for rigid cartons; ±1.0 mm is acceptable for bag palletizing where slight positional variation is absorbed by the product. Specifying tighter tolerances than needed drives cost up without operational benefit.
IP Rating for Palletizing Environments
Food and beverage plants typically require IP65 as a minimum for washdown resistance. Cold-chain facilities operating below 5°C need both IP65 and a certified low-temperature option. EVST QJAR series robots are available with IP65 standard and an extreme-temperature variant rated for operation down to -30°C, covering cold-store palletizing without auxiliary heating enclosures.
EVST Palletizing Robot Model Specifications
The following table covers the five EVST models most frequently specified for palletizing applications, spanning light cobot cells to heavy industrial end-of-line. All parameters are typical rated values; confirm exact specs with the EVST application team for your load and duty cycle.
| Model | Series | Payload (kg) | Max Reach (mm) | Repeatability | IP Rating | Typical CPM* | Footprint |
|---|---|---|---|---|---|---|---|
| XR12 | XR Cobot Palletizing Cell | 12 | 1,327 | ±0.05 mm | IP54 (IP65 opt.) | 5–8 | Compact cell, 2.4 × 2.4 m typ. |
| XR20 | XR Heavy Cobot | 20 | 1,750 | ±0.05 mm | IP54 (IP65 opt.) | 6–10 | Floor or pedestal mount |
| QJAR 130 | QJAR Industrial | 130 | 2,650 | ±0.5 mm | IP65 | 10–14 | Standard pedestal, 3.5 × 3.5 m cell |
| QJAR 180 | QJAR Industrial | 180 | 2,800 | ±0.5 mm | IP65 | 12–16 | Standard pedestal, 3.8 × 4.0 m cell |
| QJAR 300 | QJAR Industrial Heavy | 300 | 2,900 | ±0.5 mm | IP65/66 | 8–12** | Pedestal or overhead gantry, 4.5 × 4.5 m cell |
* Cases per minute at rated payload through a standard 180° pick-and-place arc. Dual-infeed configurations or partial-layer picks will differ. ** Lower CPM at max payload; lighter loads cycle faster.
According to the International Federation of Robotics (IFR) World Robotics 2025 report, palletizing and material-handling applications account for over 30% of industrial robot installations in the consumer goods and food-processing sectors globally. EVST addresses this demand with a full-range line from 12 kg cobot cells to 300 kg heavy-duty industrial palletizers, all shipping with CE, SGS, and TUV third-party certification.
Layout Configurations: Which Cell Architecture Fits Your Line?
Layout choice shapes cell cost, throughput ceiling, and changeover time as much as robot model selection does. The table below covers the four primary configurations.
| Configuration | Typical Robot | Infeed Lanes | Pallet Positions | Throughput Range (CPM) | Floor Area | Best Fit |
|---|---|---|---|---|---|---|
| Cobot compact cell | XR12 / XR20 | 1 | 1–2 | 5–10 | ~6 m² | SME, lights-out, mixed SKU |
| End-of-line single infeed | QJAR 130 / 180 | 1 | 2 | 10–16 | 12–16 m² | Single-SKU FMCG, beverage |
| Dual-infeed cell | QJAR 180 / 300 | 2 | 2–4 | 18–24 total | 18–25 m² | High-volume, two production lines |
| Overhead gantry / pedestal elevated | QJAR 300 on elevated base or linear track | 2–3 | 4–6 | 12–20 per lane | 30–50 m² | High-bay warehousing, wide pallet array |
Floor vs. Pedestal vs. Overhead Gantry
Floor-mounted robots occupy the most footprint but offer the lowest installation cost. Pedestal mounting raises the robot’s base height by 600–1,200 mm, extending effective vertical reach for high-stack tier configurations without a longer-arm model upgrade. Overhead mounting or a linear track allows one robot to serve multiple pallet positions along a travel axis, effective when floor space is constrained but vertical clearance is available. EVST’s QJAR 300 on a linear track has been deployed in cold-store environments precisely for this overhead arrangement, keeping the floor clear for forklift traffic.
Process Matching: Application Type Defines Configuration
Case Palletizing
Rigid corrugated cartons are the most common palletizing application. Vacuum gripper EOAT with two to four suction zones handles uniform case dimensions reliably. Pattern programming via a pallet pattern builder software module allows layer patterns (column stack, brick, pinwheel) to be configured without manual robot path teaching. The QJAR 130 and QJAR 180 are the standard specification for general case palletizing at 10–16 CPM.
Bag Palletizing
50 kg cement bags, 25 kg flour sacks, and 20 kg pet-food pouches all require a different EOAT strategy. A clamp-type bag gripper or a fork-style de-stacking head handles the deformation and weight distribution of filled flexible bags. The QJAR 180 and QJAR 300 cover typical bag-line payloads. Cycle rates are lower per pick because each pick covers a single bag or a paired two-bag grab; budget 8–12 CPM for bag lines.
Mixed SKU and Depalletizing
Mixed-SKU palletizing requires vision-guided pick selection. A 3D depth sensor mounted above the infeed conveyor identifies product type, orientation, and position, feeding pick coordinates to the robot controller in real time. EVST XR cobot cells with integrated vision support this workflow for SKU counts up to 30–40 varieties at modest throughput. Depalletizing (unloading inbound pallets for production feed) follows the same vision-guided approach but in reverse. The XR20 handles single-layer depalletizing of cartons up to 18 kg net product weight.
Robotic End-of-Line Integration
A complete end-of-line includes conveyor interlock, slip sheet handling, pallet dispensing, stretch-wrap turntable integration, and pallet transfer conveyors. EVST supplies turnkey cell integration (robot, EOAT, guarding, conveyor sections, and PLC/SCADA interface) as a single-source package. This avoids the interface gaps that appear when robot and peripheral suppliers are separate.
According to industry observations from CPG sector integrators, incomplete conveyor interlock design accounts for approximately 40% of palletizing cell stoppages in the first six months of operation. EVST addresses this through factory-acceptance testing (FAT) that runs the full conveyor-to-pallet sequence under simulated production conditions before shipment.
EVST Palletizing Solution Options
QJAR Series: 6-Axis Heavy-Payload Industrial Palletizers
The QJAR palletizing line covers 130 kg through 300 kg and above, designed for continuous-duty end-of-line operation. Key attributes for palletizing buyers:
- IP65 standard across the series; IP66 on QJAR 300 for washdown environments
- Extreme-temperature variant rated -30°C to 80°C for cold-chain palletizing without auxiliary heating
- IATF16949 automotive-grade manufacturing quality on QJAR production lines, with the same quality control applied to consumer-goods installations
- Built-in pallet pattern builder with 10-minute layer-pattern changeover
- EtherCAT fieldbus for direct PLC interlock and conveyor synchronization
- CE / TUV / SGS certified; ships with full documentation for customs and plant safety audits
For extended pallet arrays or high-bay stacking, pair any QJAR model with an EVST linear robot track to extend horizontal reach across two to four pallet positions without a larger footprint robot.
XR Cobot Series: Lights-Out Palletizing for SME Operations
The XR12 and XR20 cobot palletizing cells target small-to-medium manufacturers running mixed product lines at moderate throughput. The XR cell ships as a compact pre-integrated unit (robot, frame, integrated safety scanner, and plug-and-play pallet pattern software) deployable in under two days. No safety cage is required when operating in power-and-force-limiting mode, which reduces cell footprint to roughly 6 m².
In practice, XR cobot cells are well suited to lights-out overnight palletizing shifts where staffing is not available. The built-in force-limiting and collision detection mean the cell can run unattended without a full safety fence system, provided a proper risk assessment is completed per ISO 10218-2.
According to ISO 9283 (Manipulating Industrial Robots — Performance Criteria and Related Test Methods), repeatability testing under full payload at maximum reach is the authoritative method for comparing robot performance specifications. EVST’s QJAR and XR series are tested to ISO 9283 standards, and verified test reports are available on request for engineering evaluation.
Cycle Time Calculation Example
The following worked example shows how to validate a robot model against a real line requirement before ordering.
Scenario: Case Palletizing, Single Infeed, FMCG Plant
- Case dimensions: 400 × 300 × 250 mm, gross weight 12 kg
- EOAT weight: 18 kg (vacuum gripper with slip-sheet arm)
- Required throughput: 12 cases per minute (720 cases/hr)
- Pallet size: 1,200 × 1,000 mm, stack height to 1,800 mm
- Infeed conveyor pickup height: 900 mm
Step 1. Total payload: 12 kg (product) + 18 kg (EOAT) = 30 kg. Add 20% margin and specify a robot rated ≥36 kg. QJAR 130 provides 130 kg, giving large headroom for EOAT upgrades.
Step 2. Reach check: Pickup at 900 mm height, 800 mm from robot center. Pallet far corner at 1,900 mm from robot center, stack top at 1,800 mm. Required reach ≥ 2,200 mm. QJAR 130 at 2,650 mm reach is confirmed adequate.
Step 3. Cycle time: Using EVST simulation data for QJAR 130 at 30 kg payload through a 180° arc with 900 mm vertical travel: average pick-and-place cycle = 4.2 seconds. That yields 14.3 picks per minute, above the 12 CPM requirement, providing a 19% throughput buffer for conveyor accumulation delays.
Step 4. Conclusion: QJAR 130 on a standard pedestal mount with a single-infeed cell layout meets this specification. No track extension needed. Dual-pallet changeover handled by the pallet conveyor, not the robot.

Why EVST for Palletizing: Differentiation Factors
There are several areas where EVST’s palletizing offering differs from standard catalog-robot suppliers:
- Full-range payload coverage: 12 kg cobot cells through 300+ kg industrial palletizers from a single supplier, so scaling from pilot to full line does not require a supplier change.
- Cold-chain certified: The QJAR extreme-temperature variant operates at -30°C, covering frozen-food, pharmaceutical cold-store, and ice-cream palletizing without heated enclosures. That is an uncommon specification in the mid-market segment.
- IATF16949 manufacturing quality: EVST’s robot production lines carry IATF16949 automotive-grade certification. For food, pharma, and CPG buyers who run internal supplier audits, this provides an objective quality benchmark above standard ISO 9001.
- Turnkey cell integration: EVST supplies robot, EOAT, safety guarding, conveyor interface, and PLC programming as a single package. Buyers deal with one project manager, one warranty, and one after-sales contact rather than coordinating across three or four vendors.
- Global field service: With exports to 100+ countries and regional field engineers deployed across key markets, EVST supports installation, commissioning, and preventive maintenance on-site, not just remote ticket management.
- Third-party certification: CE, TUV, and SGS certificates ship with every unit. For import compliance in the EU, Southeast Asia, and the Middle East, this eliminates post-arrival certification delays.
For facilities that also run robotic welding, EVST’s welding positioners are compatible with QJAR series controllers, allowing coordinated multi-axis motion from a single control architecture if your plant runs both processes.

Frequently Asked Questions
How do I calculate the correct payload for a palletizing robot buying guide?
Add the gross product weight per pick to the EOAT weight (gripper, tooling plate, slip-sheet mechanism). Apply a 15–20% safety margin on top of that sum. The result is the minimum rated payload to specify. For example: a 15 kg case plus a 20 kg gripper assembly requires a robot rated at minimum 42 kg (35 kg × 1.20). Under-specifying payload is the primary cause of gearbox premature wear in palletizing applications.
What palletizing robot speed do I need for 15 cases per minute?
At 15 CPM you need a cycle time of 4.0 seconds or faster. For a standard 180° pick-and-place arc at typical palletizing heights, this requires a robot capable of 2,600–2,800 mm reach with a joint speed sufficient for 0.8–1.0 m/s average TCP velocity through the arc. EVST QJAR 130 and QJAR 180 meet this requirement at payloads up to 80 kg net (after EOAT deduction). Request a simulation report for your exact geometry before confirming the model.
Can a cobot handle palletizing, or do I need a full industrial robot?
For throughput below 10 CPM and product weights below 15 kg net, a cobot palletizing cell is a practical option. EVST XR20 at 20 kg rated payload and 1,750 mm reach covers most SME case-palletizing needs. The cobot cell’s advantage is a smaller footprint and no safety fence requirement in power-and-force-limiting mode. Above 15 kg per pick or above 10–12 CPM, a QJAR industrial model is the right choice for long-term duty-cycle reliability.
What IP rating is required for food and beverage palletizing robot configuration?
Most food and beverage end-of-line environments require IP65 minimum for high-pressure washdown. Chilled environments (0–5°C) need IP65 plus a low-temperature specification. Frozen or cold-store facilities below -10°C require the EVST QJAR extreme-temperature variant rated to -30°C. Confirm your facility’s cleaning protocol and ambient temperature range before specifying IP rating. Incorrect IP selection causes corrosion and electrical failures within 12–18 months of operation.
How long does it take to set up a palletizing robot cell for a new SKU or pallet pattern?
With a pallet pattern builder interface (standard on EVST QJAR and XR palletizing cells) a new layer pattern is configured by entering case dimensions and selecting a stacking pattern (column, brick, or pinwheel). No manual robot path teaching is required. Pattern changeover typically takes under 10 minutes. More complex multi-layer programs or slip-sheet insertion routines may take 20–30 minutes including test runs. This makes EVST palletizing cells viable for high-mix operations with frequent SKU changes.
