VT-220 Online Checkweigher

Product Overview

The VT-220 Online Checkweigher is a versatile mid-range weight inspection system designed for larger pharmaceutical packages including multi-unit cartons, bulk bottles, kit boxes, and secondary packaging assemblies. With a 220mm-wide conveyor belt and a weighing range of 5g to 1500g, this checkweigher handles bigger and heavier packages than compact 150mm models while maintaining reliable accuracy of ±0.2g at up to 100 packages per minute. The VT-220 Checkweigher is ideally suited for secondary packaging lines, gift set assembly, multi-pack configurations, and larger-format nutraceutical and pharmaceutical products, serving both branded drug manufacturers and generic pharmaceutical producers worldwide.

Design and Construction

Built on a robust SUS304 stainless steel frame with four adjustable leveling feet, the VT-220 Online Checkweigher provides a stable weighing platform capable of handling packages up to 300mm in length and 220mm in width. The wider conveyor belt accommodates larger cartons and multi-pack configurations without product overhang, ensuring consistent weight readings across the full product footprint. The cantilevered frame design and open underside allow easy access for belt cleaning, inspection, and maintenance - essential for GMP-compliant production environments. The infeed and outfeed sections are designed for seamless integration with existing upstream and downstream conveyor systems, and the machine can be custom-configured with side guides, hold-down devices, and product orientation rails to match specific package types.

Weighing Performance and Rejection

The VT-220 Online Checkweigher uses a high-precision strain gauge load cell with digital filtering to deliver stable and repeatable weight measurements at conveyor speeds up to 60 meters per minute. Automatic weight compensation and dynamic zero tracking maintain calibration accuracy across extended production runs, minimizing drift and reducing the need for frequent manual recalibration. The system automatically identifies and rejects underweight and overweight packages using a pneumatic push-arm rejection mechanism - the standard configuration for cartoned and boxed products - with alternative rejection methods available upon request. Rejected packages are diverted into a lockable collection bin, providing physical segregation of non-conforming product and supporting quality assurance audit requirements.
