C3000 Checkweigher System
CV3770 Combination
Checkweighing and Optical Inspection
Prevent Label Mix-Up
The visual inspection station checks
products for the correct label, expiry
date, lot/batch numbers, and labeling
defects. It inspects top, front or back
surfaces on a wide range of label and
product sizes.
Dynamic Checkweighing
The checkweighing system verifies the
weight of the product, reliably rejecting
over and under-filled products. This helps
to significantly reduce product waste and
ensures compliance with global
regulatory standards.
Complete Product Control
Combining the visual inspection with the
checkweighing eliminates unnecessary
product handling components. This
results in an easy-to-integrate unit that
saves line space and delivers unmatched
inspection accuracy.
Unified User Interface
Both system components are accessed
via the same touchscreen interface with
a user-friendly navigation and simple
product setup. A statistics module
provides real-time data to help ensure
maximum production uptime.
CV3770
Two Guardians Combined
The CV3770 offers checkweighing with inspection for
inaccurate labeling and essential prints as part of a
single product inspection process. It continuously detects
defective products, ensuring accurate certified weights,
correct labeling, packaging and verification of critical
prints. Performing multiple inspections on three surfaces
over a wide range of product sizes and with an industry
leading, easy-to-use interface, the CV3770 operates
effectively in virtually any consumer product packaging line.
Manufacturers benefit from the CV3770 system as follows:
• Immediate detection of label mix-up, saving recovery
and rework costs and minimizing the risk of recall
• Control of labeling and print quality, maximizing product
sales and consumer satisfaction
• Unit is part of an overall quality control system, meeting
retailers' demands for certification
Get protected, with two state-of-the-art control points in a
single unit that help facilitate the implementation of BRC
and IFS quality assurance criteria.
