Smooth transfers
Matched belt heights, nose-bar geometry and side-guide transitions reduce shock and wobble as containers enter and leave the weigh conveyor.
Stable container handling
Bottle and jar checkweighers with controlled transfers and reliable rejection
Weigh filled bottles and jars at line speed while maintaining stable handling through the infeed, weigh section and reject station. The design can accommodate glass, plastic and metal containers across food, beverage, cosmetic, pharmaceutical and chemical applications.

System design
Container control matters as much as weighing performance
Upright containers need matched transfers, side guides and a reject action that removes the failed bottle or jar without destabilising adjacent products.
Correct spacing
Timing screws, spacing belts or gating can be considered when containers arrive touching or at an inconsistent pitch.
Appropriate rejection
Pusher, sweep and guided-divert arrangements can remove non-conforming containers without toppling adjacent product.
Fill-process insight
Net or gross-weight trends can identify filler drift, blocked nozzles or inconsistent dosing when tare variation is properly understood.
Specification
Information needed for bottle and jar weighing
- Container material, diameter, height and centre of gravity
- Full and empty weight range, including tare variation
- Cap or closure type and whether the pack may be wet
- Line speed, container pitch and accumulation pressure
- Guide-rail contact points and label protection
- Reject direction, containment and glass policy
- Filler feedback and upstream/downstream interlocks
Line integration
From filler discharge to final pack verification
Bottle and jar projects often sit alongside cap inspection, fill-level vision, label verification, code reading and leak detection. A coordinated control design can associate weight and visual checks with the same product flow, while a common reject philosophy helps operators investigate faults efficiently.

Combine weight with barcode, label and product verification
Gross weight can be combined with direct checks for cap presence, fill level, label position and printed codes, with each fault linked to the agreed line response.

Questions about bottles & jars
These answers explain how container material, tare variation, pitch and rejection affect a realistic acceptance test.
Can a checkweigher handle glass jars?
Yes, with transfers, guides and reject handling designed for the container. Your glass and breakage policy should be considered as part of the line risk assessment.
Can it distinguish a missing cap by weight?
It may be possible when cap weight is clearly greater than normal combined product and container variation. Vision inspection is often the more direct check for cap presence and position.
Can it send corrections to a liquid filler?
Yes, where the filler accepts suitable control signals. Feedback logic is based on a stable rolling trend rather than reacting to a single container.
What happens to an underweight bottle?
It is tracked to the selected reject point and diverted into the agreed containment area, with optional confirmation that the reject action completed.

Filler feedback
Turn downstream weight measurements into controlled adjustments at the filler. Rather than reacting to one pack, feedback logic evaluates a defined sample and applies bounded corrections when a genuine process trend is established.

Reject systems
A weight result only protects production when the correct item is removed and its removal is confirmed. We select the reject principle around pack behaviour, throughput, available length and the way your quality team needs to contain and reconcile non-conforming product.
