Português do Brasil7 Tips for Choosing a Pick And Place Robot?
Choosing the right Pick And Place Robot can determine whether an automation project runs smoothly or struggles daily. The decision is rarely based on speed alone. A robot may move 120 parts per minute, yet fail when components arrive slightly misaligned. Real production conditions matter: dusty trays, changing product sizes, tight workspaces, and operators who need simple adjustments.
This guide presents seven practical tips for evaluating a Pick And Place Robot. It considers payload, reach, cycle time, accuracy, tooling, vision systems, safety, maintenance, and supplier support. These factors should connect with your actual workflow, not only with figures printed in a brochure. During equipment reviews, technicians often discover that a smaller robot fits better and costs less to maintain. I have also seen teams prioritize maximum speed, then face vibration, poor gripping, or difficult programming. That mistake is easy to make.
Look closely.
Reliable selection requires measurable evidence. Request sample testing with your real parts, packaging, and production speeds. Check how the robot behaves after repeated cycles, not just during a short demonstration. Confirm electrical requirements, guarding expectations, spare-part availability, and training options with qualified professionals. Standards and local workplace rules should guide the final installation. No model is perfect for every factory, and that is worth admitting. The best choice balances performance, flexibility, safety, and long-term operating value. These seven tips will help turn a promising specification into a dependable automation decision.
Define Throughput Targets: Compare 30–200 Picks per Minute by Application
Choosing a pick-and-place robot starts with a realistic throughput target, not the highest advertised speed. Applications may range from 30 to 200 picks per minute. A 30-pick task may involve heavy items, long travel, or careful placement. A 200-pick task usually needs lightweight products, short movements, and consistent presentation.
Define whether one pick means one item or one complete handling cycle. Then measure product arrival, gripping, transfer, release, and return time. Include pauses caused by inspection, refilling, or conveyor gaps. In production trials, I have seen theoretical speed fall sharply when products arrive unevenly. That difference matters. A robot rated for 200 picks per minute may deliver only 150 in a stable operation.
Test the robot with real products and the intended gripper. Product texture, size variation, and orientation can change the result. Leave practical capacity for cleaning, minor stoppages, and operator adjustments. A useful target may be 70–85% of the laboratory maximum. I once treated a short test as representative, and the estimate was too optimistic. That mistake reinforced a simple rule: compare net throughput, not brochure speed. Record results across several shifts before selecting the final model.
| Application | Typical Throughput Target | Approximate Cycle Time | Common Product Characteristics | Recommended Robot Considerations | Throughput Risks to Check |
|---|---|---|---|---|---|
| Case Packing of Bottles or Cans | 30–60 picks/min | 1.0–2.0 seconds per pick | Rigid products, generally consistent dimensions, moderate-to-high unit weight | Payload capacity, grip reliability, carton pattern control, and reach across the case | Product collisions, unstable stacks, carton indexing delays, and gripper changeover time |
| Primary Food Packaging | 60–120 picks/min | 0.5–1.0 seconds per pick | Lightweight, hygienic, frequently changing product orientation | High-speed motion, food-compatible materials, washdown suitability, and gentle gripping | Irregular product spacing, damaged packaging, sanitation cycles, and product slippage |
| Bakery or Snack Collation | 80–140 picks/min | 0.43–0.75 seconds per pick | Light, delicate products with variable shapes and surface textures | Low-inertia tooling, vision guidance, soft contact surfaces, and accurate placement | Crushing, crumbs or debris affecting vacuum, inconsistent product presentation, and belt speed variation |
| Cartoning of Small Consumer Goods | 50–100 picks/min | 0.6–1.2 seconds per pick | Small packaged items with defined orientation and moderate presentation consistency | Compact work envelope, repeatability, synchronized infeed, and quick recipe changes | Open cartons, poor product separation, barcode or vision verification delays, and frequent format changes |
| Pharmaceutical or Medical Sorting | 30–80 picks/min | 0.75–2.0 seconds per pick | Small, lightweight products requiring traceability and controlled handling | Validated motion profiles, cleanable construction, vision inspection, and data logging | Inspection rejects, batch changeovers, serialization checks, and strict handling requirements |
| E-Commerce Item Picking | 40–100 picks/min | 0.6–1.5 seconds per pick | Mixed shapes, sizes, materials, and packaging formats | 3D vision, adaptive gripping, broad payload range, and software integration with order systems | Unknown product geometry, occlusion, reflective surfaces, failed grasps, and SKU variability |
| High-Speed Part Sorting | 120–200 picks/min | 0.30–0.50 seconds per pick | Small, lightweight parts presented in a controlled orientation | Fast delta-style motion, high-speed vision, short conveyor pitch, and optimized end-of-arm tooling | Insufficient spacing, vibration, missed detections, excessive acceleration, and tooling wear |
| Planning note: These are practical planning ranges rather than guaranteed robot ratings. Actual throughput depends on product weight and geometry, pick-point spacing, robot reach, conveyor speed, end-of-arm tooling, vision performance, placement accuracy, reject handling, changeovers, and required line availability. Validate the target with a time study using representative products and packaging. | |||||
