High-speed pick and place: specify sustained production rate

High-speed pick and place should be specified in good products delivered per scheduled hour, with the agreed mix and operating conditions. A robot's fastest repeated move does not include every delay in feeding, image processing, gripping, placement, and recovery. Buyers get a more useful comparison by defining the complete production window and asking suppliers to prove performance inside it.

Define the rate and the time window

State the normal production requirement, short-duration peak, product spacing, and permitted backlog. Include the largest part, heaviest part, and most delicate part; these may be different products. Identify how the process responds when arrivals exceed available picking capacity. Options might include a controlled upstream pause, a buffer, recirculation, or an agreed exception route.

For a hypothetical planning calculation, a one-second complete cycle offers 3,600 cycles per hour before interruptions. If the proposed schedule reserves twelve minutes each hour for replenishment and planned stops, only 2,880 such cycles remain. Product misses and rejected placements reduce good output further. This arithmetic is a planning example, not a robot benchmark.

Before fixing an arm architecture, compare motion requirements with our robot arm type guide. Part orientation, vertical travel, and available access can matter as much as the shortest nominal cycle.

Review conveyor timing as a system

For moving products, ask when position is measured, how movement is tracked, and when a pick becomes too late to execute. Define the usable picking region and how the system treats a product that exits it. Request behavior for conveyor acceleration, stopping, restart, and spacing changes.

ABB's PickMaster software combines picking workflows with vision and conveyor tracking. In a supplier review, ask for a timing diagram showing those functions in the quoted cell. A camera result must still correspond to the item at the time and place where the gripper acts.

The research paper Toward Fast and Optimal Robotic Pick-and-Place on a Moving Conveyor investigates how pick ordering affects efficiency. For purchasing, the practical inference is to test crowded and uneven arrival sequences, not only evenly spaced demonstration parts. Do not apply the paper's experimental gains to an unrelated production line.

Separate grip time from travel time

Build a cycle breakdown that includes approach, grip establishment, confirmation, transfer, placement, release confirmation, and return. Ask which operations overlap and which must finish before the next can start. A lightweight part may still require a slow approach if it deforms, tips, or sticks to its neighbor.

Use our pick-and-place vision guide to specify imaging. Cognex's guided pick-and-place example trains separate reference poses for picking and placement. That illustrates why a good pickup does not establish that the destination relationship is correct.

Choose a trial that exposes lost output

Measure supplied products, attempted picks, successful grips, acceptable placements, and recirculated or rejected items separately. Report elapsed time and reasons for all stops. Otherwise, a supplier can demonstrate a high cycle rate while silently leaving difficult products for an operator.

Include representative product finishes, natural spacing variation, packaging lots, and temperature conditions relevant to your process. Run with the actual destination fixture or conveyor. Test approved recovery scenarios under the integrator's procedures and measure the time until normal production resumes. Have qualified personnel assess the complete high-speed application and safeguards.

Compare scope and changeover effort

Request a complete quotation for feeding, conveyors, vision, robot, tooling, controls, guarding, integration, and training. Identify who owns tuning when a product or package changes. Ask for the time and skills required to move between the agreed recipes, plus the evidence that the new setup is ready to run.

Check FAIRINO against the sustained-rate requirement

Include a FAIRINO pick-and-place concept when its proposed motion and tooling can meet your sustained good-output target. Begin with the pick-and-place application requirements and FAIRINO model comparison, then require a complete cycle trial with representative product spacing. Request a FAIRINO pick-and-place quote using the measured arrival profile, part samples, and placement tolerance. Compare the resulting cell budget and tested rate with other handling architectures, including the feeding and recovery equipment each needs.
