Product transfer
Conveyor height, gaps, speed matching, guides and belt surfaces should keep packs settled through measurement.

Checkweigher installation and integration: plan the complete inspection point
A checkweigher can pass a workshop test and still underperform if the surrounding line creates unstable packs, vibration, poor spacing or ambiguous controls.

Short answer
What is included in checkweigher integration?
Integration connects the weighing machine to the physical line, product flow, reject system, guards, safety circuit, upstream and downstream equipment, recipes, alarms and production records. The scope should also define FAT, delivery, installation, SAT, training and production acceptance.
Project decisions
What the final scope needs to define
Spacing and tracking
Upstream gating or speed control may be needed to prevent touching packs and preserve reject identity.
Reject and guarding
Mechanism, containment, access and safety design must allow confirmed removal without a new hazard.
Line controls
Define ready, run, stop, fault, bypass and restart behaviour before software testing.
Data and recipes
Agree product identifiers, recipe ownership, result exchange, batch reporting and time synchronisation.
Maintenance access
Allow safe access for belt release, cleaning, checks, sensors and replacement of wear components.
Project route
From site survey to production handover
Application review
Confirm products, performance, layout, environment and the quality decision.
Engineering design
Issue layout, interface, guarding and control documents with responsibilities.
Factory acceptance
Test products, recipes, faults, rejection and records against agreed criteria.
Site preparation
Complete utilities, access, surrounding conveyors and production planning.
Installation and SAT
Prove the system in the real line at the required rate and challenge critical responses.
Training and handover
Provide settings, reports, drawings, spares information and training.
Application-led engineering
Review the line before the machine is specified.
A line video, layout and product sample set can expose transfer, spacing and access risks early.

Checkweigher integration FAQs
How much straight length is needed?
It depends on product length, speed, weigh-belt length, reject method and surrounding transfers. Use the actual application.
Can the checkweigher stop the line?
Yes. Stop conditions can include failed rejection, full bin, lost tracking, repeated weight faults or a machine fault.
What is the difference between FAT and SAT?
FAT tests agreed machine functions before delivery. SAT proves the installed system within the real production line.
