Automatic Carton Weight Inspection System for Macaroni and Pasta Packaging Lines

Custom Attributes

Product Overview

The Macaroni Box Checkweigher is designed for automatic weight verification of boxed macaroni, pasta products, and dry food cartons. Installed after the cartoning machine, the system performs real-time dynamic weighing to identify underweight, overweight, or incomplete packages before case packing and palletizing operations.

Using a high-precision weighing sensor and intelligent control system, the machine helps food manufacturers maintain packaging consistency and product quality throughout the production process.

Why Do Pasta Manufacturers Need a Checkweigher?

As packaging lines become increasingly automated, product weight verification is an important quality control step.

Common challenges include:

1. Missing Product Detection

Missing pasta pouches or seasoning sachets can result in customer complaints and product returns.

2. Underweight Cartons

Weight deviations may lead to non-compliant retail packaging.

3. Overfilled Products

Excessive filling increases product giveaway and production costs.

4. Quality Assurance Requirements

Food manufacturers require reliable in-line inspection before products enter the distribution chain.

How the Macaroni Box Checkweigher Works

Carton Infeed

Finished cartons are automatically transferred onto the weighing conveyor.

Dynamic Weight Measurement

Each carton is weighed while moving through the inspection section.

Weight Comparison

The actual weight is compared with preset tolerance limits stored in the control system.

Automatic Rejection

Non-conforming cartons are automatically removed through a pusher reject mechanism.

Qualified Product Discharge

Accepted cartons continue to downstream case packing and palletizing systems.

Core Features

High-Precision Weighing

Equipped with a Mettler Toledo high-precision load cell for dynamic weighing applications.

High-Speed Inspection

Supports inspection speeds exceeding 75 cartons per minute for continuous production environments.

Automatic Reject System

The pusher reject mechanism automatically removes products outside the acceptable weight range.

Food-Grade Construction

The machine adopts SUS304 stainless steel construction and wear-resistant PU conveyor belts.

Data Connectivity

MODBUS TCP communication enables integration with packaging lines and factory automation systems.
