Small Bottle Checkweigher

This checkweigher enables stable conveyance and high‑precision weighing of products in small-diameter, slim bottles—such as eye drops, nasal drops, and cosmetics—that are prone to tipping over.

Achieving both stable conveyance and high-precision weight inspection.

This checkweigher enables stable conveyance and high‑precision weighing of products in small-diameter, slim bottles—such as eye drops, nasal drops, and cosmetics—that are prone to tipping over.

Stable transfer with side belt conveyor

A motor-driven side belt conveyor with a soft sponge belt supports smooth and stable transfer between conveyors.This ensures reliable conveyance of products in various shapes—square, round, or oval—that are difficult to transport while standing.The passage width can also be easily adjusted using the indicator.In the unlikely event that a product falls over, a sensor-based length detection function (optional) automatically detects the abnormality and force‑rejects the product.

Fall prevention with side belt conveyor with indicator

Supports FDA 21 CFR Part 11 (Optional)

Audit trail

Operations history, production-related actions, and operation check results are recorded internally. These records can be used to monitor unauthorized or incorrect operations and analyze their causes.

Eligibility authentication (User management)

Access levels can be set individually for each user to prevent unauthorized operations and operator errors.

Data encryption and decryption

Various data—including statistical data and parameter data compliant with data-integrity requirements—can be securely exported.
