High Speed Checkweighing

Plan high speed checkweighing around representative good, bad and marginal samples, line presentation, lighting, reject handling and challenge criteria. Discuss an optical feasibility trial with Oxford Vision Systems.

Speak directly with Oxford Vision Systems about checkweighing at high production rates.

In brief

Choose high speed checkweighing by defining visible defect or measurement definition for checkweighing at high production rates, good, bad and marginal sample range, optics, lighting and environmental conditions, and false-accept, false-reject and challenge criteria, then prove the preferred method using representative good, bad and marginal samples before the final system is specified.

Your final high speed checkweighing scope must also account for recipe, reject and line-control interfaces, false-accept, false-reject and challenge criteria, current regulations and the conditions at your site.

Quick answer

How do we assess checkweighing performance at our required line speed?

For high speed checkweighing, define visible defect or measurement definition for checkweighing at high production rates and collect good, bad and marginal sample range before choosing cameras. An optical trial should prove contrast, presentation and timing, followed by agreed checks for false-accept, false-reject and challenge criteria.

Six useful questions

Describe what you need from high speed checkweighing before choosing a solution

For in-line inspection using checkweighing at high production rates, share the normal condition, realistic range and difficult cases the finished system must handle.

Question 1

Visible Defect or Measurement Definition for Checkweighing At High Production Rates

For your initial enquiry about high speed checkweighing, describe the current position, required outcome, acceptable limits and known exceptions for visible defect or measurement definition for checkweighing at high production rates. That lets us compare options against your real production rather than one nominal value.

Question 2

Good, Bad and Marginal Sample Range

For your initial enquiry about high speed checkweighing, describe the current position, required outcome, acceptable limits and known exceptions for good, bad and marginal sample range. That lets us compare options against your real production rather than one nominal value.

Question 3

Part Presentation and Production Speed

For your initial enquiry about high speed checkweighing, describe the current position, required outcome, acceptable limits and known exceptions for part presentation and production speed. That lets us compare options against your real production rather than one nominal value.

Question 4

Optics, Lighting and Environmental Conditions

For your initial enquiry about high speed checkweighing, describe the current position, required outcome, acceptable limits and known exceptions for optics, lighting and environmental conditions. That lets us compare options against your real production rather than one nominal value.

Question 5

Recipe, Reject and Line-Control Interfaces

For your initial enquiry about high speed checkweighing, describe the current position, required outcome, acceptable limits and known exceptions for recipe, reject and line-control interfaces. That lets us compare options against your real production rather than one nominal value.

Question 6

False-Accept, False-Reject and Challenge Criteria

For your initial enquiry about high speed checkweighing, describe the current position, required outcome, acceptable limits and known exceptions for false-accept, false-reject and challenge criteria. That lets us compare options against your real production rather than one nominal value.

Applications

Two useful starting points for high speed checkweighing

The right choice changes with visible defect or measurement definition for checkweighing at high production rates, good, bad and marginal sample range, your line layout and required results.

What happens next

Your route from an initial enquiry to a working solution

You can review decisions about recipe, reject and line-control interfaces and false-accept, false-reject and challenge criteria at each stage.

  1. 01

    Define the Visible Decision and Collect Representative Samples

    Share representative good, bad and marginal samples, including the normal range for visible defect or measurement definition for checkweighing at high production rates and the difficult good, bad and marginal sample range cases.

  2. 02

    Prove Contrast, Presentation and Timing in an Optical Trial

    Compare suitable methods and use focused trials to show how each option performs against part presentation and production speed.

  3. 03

    Integrate Cameras, Controls, Reject Handling and Recipes

    Connect the equipment to your line, services and controls while resolving optics, lighting and environmental conditions for day-to-day operation.

  4. 04

    Challenge Marginal Cases and Document Agreed Results

    Confirm recipe, reject and line-control interfaces, then complete and record false-accept, false-reject and challenge criteria before your operating team takes over.

Important limits

Know what needs a separate check

Your final solution for checkweighing at high production rates must reflect the law, current standards and site-specific risks that apply to your installation.
