In brief

A useful specification for bottle checkweighers describes your operating range, line connections and required results while leaving room for the supplier to propose the best method.

Use this checklist for in-line inspection using dynamic weighing of filled bottles and separate confirmed facts, realistic ranges and items that need a trial.

On the production floor

Describe what the complete process needs to achieve — Bottle Checkweighers

Plan bottle checkweighers around representative good, bad and marginal samples, line presentation, lighting, reject handling and challenge criteria. Discuss an optical feasibility trial with Oxford Vision Systems. A clear brief should state the operating range for visible defect or measurement definition for dynamic weighing of filled bottles and your requirements for false-accept, false-reject and challenge criteria.

For Bottle Checkweighers, turn each checklist item into a range and a test

Requirement

State what the complete solution must achieve for in-line inspection using dynamic weighing of filled bottles, including your production pattern and who will review the result.

Range

Record normal and credible extremes for visible defect or measurement definition for dynamic weighing of filled bottles, good, bad and marginal sample range and part presentation and production speed; avoid relying on one nominal value.

Check

Define representative examples from in-line inspection using dynamic weighing of filled bottles, the method, repetitions, acceptable range and result record so you and the supplier share the same expectation.

For bottle checkweighers, use “shall” only for a requirement that can be demonstrated. Keep preferences, assumptions, provisional line connections and future options clearly separate.

Connected responsibilities

Be clear about what sits around your bottle checkweighers

Your final bottle checkweighers 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.
